(Embodiment 1)
FIG. 1 is a perspective view showing the surface side of a magnet-attached binder according to Embodiment 1 of the present invention. FIG. 2 is a perspective view showing the back side of the binder. In addition, the perspective view attached to this specification is expressed in consideration of perspective. This binder 101 with a magnet also corresponds to an embodiment of the magnet holder of the present invention. The binder with magnet 101 has a magnet holding base 1, a ring binder 2, and a magnet 3 as basic components. The binder 101 with a magnet has a magnet holding base 1 attached to a magnetic wall (not shown) such as a steel wall by the magnetic force of the magnet 3 while a paper sheet such as a calendar or memo paper is suspended from the ring binder 2. By adsorbing, it is possible to hold these sheets on the magnetic wall and post them, for example. 1 and 2 also show the posture of the binder 101 with magnet in such a normal use state. The magnet holding base is abbreviated as “base” as appropriate.

  As an example, the base 1 is a plate having a long rectangular main surface in a direction along one side, that is, a long rectangular plate, and has a scale 11, a pair of hanging holes 12, and a magnet 3. And an opening 13 for receiving the. The base 1 is formed, for example, by molding plastic. Plastic has moderate rigidity. The scale 11 is formed along the upper side which is one of the long sides of the base 1 in FIG. 1, and allows the base 1 to be used as a ruler. The pair of suspension holes 12 are formed so as to penetrate from the front surface to the back surface of the base 1 near the upper side of the base 1 and near both left and right ends. The pair of suspension holes 12 allows the binder 101 with magnet to be suspended from a wall or the like by passing a suspension strap (not shown). The opening 13 is formed so as to be located at a central portion in the left-right direction of the base 1 and close to the upper side when the binder 101 with magnet is in the posture shown in FIGS. 1 and 2, that is, the posture in a normal use state. And is formed so as to form a long rectangle extending in the left-right direction. The opening 13 accommodates the magnet 3 and holds the magnet 3 so as not to fall off.

  The ring binder 2 is fixed to the surface of the base 1 (main surface shown in FIG. 1), and includes a ring support portion 21, a pair of rings 22, a pair of levers 23, and a pair of caulking 24. Yes. The ring support portion 21 supports the pair of rings 22 so that they can be opened and closed. The lever 23 opens the pair of rings 22 by being pushed down manually. The caulking 24 is a fastening member, and the ring support portion 21 is fixed to the base 1 by being caulked. As will be described in detail later, the ring support portion 21 has a closed maintaining mechanism that maintains the closed state once the pair of rings 22 are once closed manually. Each member of the ring binder 2 is made of, for example, metal so as to have a certain degree of rigidity and strength.

  Each of the pair of rings 22 has an upper arm portion located on the upper side and a lower arm portion located on the lower side in the original use posture, and is rotated so that they are separated from each other or connected to each other. Open and close by. The lower arm portion has a linear portion 28 that rises obliquely upward as it gets farther from the ring support portion 21 in the closed state and approaches the tip end portion of the lower arm portion. Thereby, even when there are a plurality of paper sheets (not shown) suspended from the pair of rings 22, the plurality of paper sheets are in close contact with each other and are stably supported on the magnetic wall side. In addition, the upper arms of the pair of rings 22 have a linear portion 29 that rises obliquely upward as it gets farther from the ring support 21 in the closed state and approaches its own tip. Thereby, a writing instrument (not shown) such as a pencil can be stably placed on the pair of rings 22.

  The magnet 3 is a plate-like permanent magnet having a long rectangular main surface in a direction along one side, that is, a long rectangular plate-like magnet. The magnet 3 is attracted to a magnetic body wall (not shown), whereby the binder 101 with a magnet is attached. It is held on the magnetic wall. The magnet 3 desirably has a strong magnetic force such as a neodymium magnet. The binder 101 with magnet is held so that the back surface (main surface shown in FIG. 2) of the base 1 faces the magnetic wall. As a result, one or a plurality of paper sheets (not shown) are suspended from the pair of rings 22 of the ring binder 2 attached to the magnetic binder 101 held on the magnetic wall and held on the magnetic wall. For example, it can be posted. In addition, since the paper sheet is suspended by passing the pair of rings 22 through the pair of holes formed in the paper sheet, there are a plurality of paper sheets to be held, and when the attachment / detachment and replacement are performed The paper sheets are difficult to be scattered, and a plurality of paper sheets can be easily formed into pages and bound. Since the magnet 3 is a plate-like body whose main surface is a simple rectangle, it is easy to manufacture. Furthermore, since the magnet 3 is a long rectangular plate-like body extending in the direction along one side, the volume of the magnet 3 is reduced and the magnet 3 is attracted to the magnetic body wall on the magnetic wall surface of the binder with the magnet. Inadvertent rotation can be effectively suppressed.

  FIG. 3 is a partial cross-sectional view of the magnet-attached binder 101 and shows a state in which the magnet 3 is accommodated in the opening 13. 3A is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 3B is a cross-sectional view taken along the line BB in FIG. 4 shows the vicinity of the opening 13 of the base 1, FIGS. 4 (a) and 4 (b) are partial plan views, and FIG. 4 (c) is a partial bottom view. FIG. 4A particularly shows a state before the magnet 3 is accommodated. The opening 13 is formed so as to communicate from the front surface of the base 1 to the back surface. A pair of projecting portions 16 projecting inward of the opening portion 13 are formed at the left and right direction end edges on the surface side of the opening portion 13, that is, the long side direction end edges. The protrusion 16 can be retracted outwardly of the opening 13 and can widen the entrance of the opening 13, thereby allowing the magnet 3 to be inserted into the opening 13. Further, the protruding portion 16 locks the magnet 3 so as to prevent the magnet 3 once inserted from returning backward, that is, from falling off to the surface side.

  A groove 17 is formed in the base 1 on the rear side of the protruding portion 16 when viewed from the opening 13. As shown in FIG. 3A, the protruding portion 16 is connected to the remaining portion of the base 1 through the connecting portion 93. The connecting portion 93 has a peninsular shape and is connected to the remaining portion of the base 1 at the bottom. When the connecting portion 93 is elastically deformed toward the groove 17, the projecting portion 16 is retracted outward from the opening portion 13, thereby expanding the entrance of the opening portion 13. That is, the protrusion 16 and the connecting portion 93 enable the magnet 3 to be inserted into the opening 13 and prevent the permanent magnet 3 once inserted from returning backward, that is, falling off to the surface side. It corresponds to an example of the “detent member” of the invention. In the example shown in FIGS. 4A and 4B, the connecting portion 93 is provided with a gap with the remaining portion of the base 1 not only on the rear side facing the groove 17 but also on the side. Yes. On the other hand, although the side of the connecting portion 93 is separated from the remaining portion of the base 1 without being connected, it is possible to implement a form in which there is no gap between the remaining portion and the remaining portion.

  The protrusion 16 has a guide surface 218 that is inclined so as to narrow the entrance of the opening 13 as it descends from the upper surface of the base 1 to the opening 13. In the example of FIG. 3A, the guide surface 218 is formed as an arc surface or a substantially arc surface. When the magnet 3 is inserted into the opening 13 from the front side of the base 1, the guide surface 218 pushes the edge of the magnet 3 against the guide surface 218, thereby retreating the projecting portion 16, and entering the entrance of the opening 13. It is possible to expand. The guide surface 218 can be formed as a flat surface or a curved surface other than a substantially arc surface.

  In the vicinity of the back surface side of the side wall of the opening 13, an overhanging portion 18 that protrudes inward of the opening 13 is formed. The overhanging portion 18 is formed so as to form a slope at the edge of the opening 13 in the long side direction. The overhanging portion 18 functions as a locking member that locks the magnet 3 so as to prevent the magnet 3 from falling off from the opening 13 to the back surface side. A receding portion 31 for allowing the overhanging portion 18 to escape is formed on the edge of the back surface of the magnet 3 in the long side direction. In the example of FIG. 3, the receding portion 31 is formed as an inclined surface that is inclined so as to go inward of the back surface as it approaches the back surface side of the magnet 3. Corresponding to this, the overhanging portion 18 provided on the base 1 is formed so as to have a slope facing the retreating portion 31 of the magnet 3. Since the retracted portion 31 is formed in the magnet 3, the thick magnet 3 can be accommodated in the opening 13.

  The magnet 3 is accommodated in the opening 13 with a certain amount of play in the left-right direction of the opening 13, that is, in the direction along the long side and in the depth direction. This makes it easier to insert the magnet 3 into the opening 13 described below. 4B and 4C show an example in which the magnet 3 is accommodated in the opening 13 with some play in the vertical direction of the opening 13, that is, the direction along the short side. ing. The magnet 3 may or may not be fixed in the opening 13 with an adhesive after being inserted into the opening 13. From the viewpoint of simplification of the manufacturing process, it is desirable that the adhesive is not fixed. Since the base 1 has a structure for holding the magnet 3 in the opening 13 even without an adhesive, the magnet 3 can be held with a long durability regardless of whether or not the adhesive is fixed. When the magnet 3 is fixed to the opening 13 with an adhesive, it is preferable that the magnet 3 is fixed in a state where the back surface of the magnet 3 is slightly advanced from the back surface of the base 1.

  FIG. 5 is a process diagram showing a process of inserting the magnet 3 into the opening 13 of the base 1 in the process of manufacturing the binder 101 with magnet. In order to insert the magnet 3 into the opening portion 13, as shown in FIG. 5A, first, one of the end portions in the long side direction of the magnet 3 is inserted between the protruding portion 16 and the overhang portion 18. . Next, the one end of the magnet 3 is pressed against the connecting portion 93 so that the one projecting portion 16 (the left projecting portion 16 in FIG. 5A) is retracted toward the rear groove 17 side. Let As a result, the left and right widths of the opening 13 can be increased. Next, while keeping this state, the other end of the magnet 3 is pushed down, and the other protrusion 16 is pushed open to the rear side of the groove 17. Since the guide 16 is formed on the protrusion 16, the protrusion 16 can be easily retracted by pressing the end of the magnet 3. The fact that the retreating portion 31 on the back surface of the magnet 3 is formed as an inclined surface also makes the retreating portion 16 easier to retreat. By doing so, the other end portion of the magnet 3 can be placed on the overhanging portion 18 positioned below the projecting portion 16 through the other projecting portion 16. Thereby, the magnet 3 is stored in the opening 13.

  In the process of FIG. 5A, the magnet 3 rotates with a certain angle around one end (left end in FIG. 5A) as an axis. Since there is play in the left-right direction and the depth direction between the magnet 3 and the opening 13, this rotation is facilitated, so that the magnet 3 can be easily inserted into the opening 13. As shown in FIG. 5B, when the magnet 3 is accommodated in the opening 13, the pair of protrusions 16 that have been retracted toward the groove 17 are both released from the pressing force from the magnet 3. Thus, the original position is restored by the elastic restoring force of the connecting portion 93. As a result, the magnet 3 is supported without coming out of the opening 13 in any direction. Furthermore, the back surface of the magnet 3 can protrude slightly from the back surface of the base 1 outward. That is, it is possible to cue the back side of the magnet 3, that is, the part including the back side of the magnet 3 from the back side of the base 1 while leaving most of the magnet 3 in the opening 13. Thereby, the magnet 3 can be attracted to the magnetic body wall 5 without being hindered by the base 1 and floating from the magnetic body wall 5. That is, the magnetic force of the magnet 3 is effectively used for the attractive force to the magnetic body wall 5 while making the magnet 3 compact so that the magnet 3 is approximately within the thickness range of the base 1.

  If the magnet 3 is not fixed to the opening 13 by a fixing means other than the protrusion 16, for example, by using an adhesive, the magnet 3 is retracted by a finger so as to widen the entrance of the opening 13. It is possible to remove from the opening 13. As described above, the magnet 3 can be attached to and detached from the opening 13 unless a fixing means other than the protruding portion 16 is used. Therefore, the user can attach the magnet 3 to the opening 13 or remove it from the opening 13 as necessary. Thereby, for example, it becomes possible to use the binder 101 with a magnet for use on a desk in the state which removed the magnet 3 from the opening part 13. FIG.

  FIG. 6 is a diagram showing the configuration of the ring binder 2, FIG. 6 (a) is a front view of the binder 101 with magnet, and FIG. 6 (b) is a bottom view of the ring binder 2. The ring binder 2 is formed by engaging and disposing in parallel two elongated metal spring plates 26 to which a pair of metal rings 22 arranged along the longitudinal direction are fixed, so that they are not decomposed in the air. It has a structure of being wrapped with a cover 25 made of metal. That is, the ring support portion 21 has two jump plates 26 and a cover 25. The metal lever 23 is configured to tilt around the fulcrum by the lever principle with both ends of the cover 25 as fulcrums. A cylindrical eyelet 92 having a through hole through which the caulking 24 is inserted is fixed at two locations along the longitudinal direction of the cover 25. A hole (not shown) is formed in a corresponding portion of the spring plate 26, and the eyelet 92 is inserted through this hole. For this reason, the operation of the jump plate 26 is not interfered by the eyelet 92. Further, the base 1 is also formed with through holes 14 at corresponding portions. The cover 25 is fixed to the base 1 by caulking 24 inserted through the through hole 14 and the eyelet 92. The eyelet 92 ensures the normal operation of the jump plate 26 by holding the cover 25 at a certain height from the base 1 against the fastening force of the caulking 24.

  7A and 7B are cross-sectional views for explaining the usage of the binder 101 with magnet together with the operation of the ring binder 2. FIG. 7A shows a state in which the ring is opened, and FIG. 7B shows a state in which the binder is closed. Represents. Both FIG. 7A and FIG. 7B correspond to cross-sectional views of the binder 101 with magnet along the CC cutting line of FIG. 6B. As shown in FIGS. 7A and 7B, when the binder 101 with magnet is held on the magnetic body wall 5 so as to maintain the original posture, the arrangement direction of the pair of rings 22 becomes the horizontal direction. When one end of the lever 23 exposed from both ends in the longitudinal direction of the cover 25 (see FIGS. 6A and 6B) is pressed with a finger, the action portion 27 as the other end jumps up, thereby The joint between the two spring plates 26 is pushed up. As a result, the pair of rings 22 in the closed state are simultaneously displaced to the open state. FIG. 7A shows this open state. The pair of rings 22 in the open state can be returned to the closed state at the same time by pinching one or both of them with a finger. The pair of rings 22 that have once shifted to the closed state are maintained in the closed state by the elastic force of the two spring plates 26. That is, the ring support portion 21 is provided with a closed maintaining mechanism that holds the pair of rings 22 that are once closed in a closed state.

  Since the above mechanism of the ring binder 2 is well known as a loose-leaf file binder, further explanation is omitted. In addition, it is also possible to take the form which does not provide the lever 23 as the ring binder 2. FIG. In this case, the pair of rings 22 can be simultaneously displaced to the open state by pushing one or both of the pair of rings 22 in the closed state with a finger with a certain amount of force.

  Each of the pair of rings 22 has an inclined linear portion 28 in the lower arm portion and an inclined linear portion 29 in the upper arm portion. Even when there are a plurality of paper sheets 51 hung on the pair of rings 22 by the linear portion 28, the plurality of paper sheets 51 are in close contact with each other and stably supported on the magnetic body wall 5 side. In addition, the linear portion 29 allows the writing tool 52 such as a pencil to be stably placed on the pair of rings 22. That is, a place for the writing instrument 52 is secured in the binder 101 with magnet itself. This configuration is particularly useful when the paper sheet 51 is a memo paper, or when it also serves as a memo paper.

  As described above, a file binder is known as a binding tool for storing the paper sheet 51 in the form of a book or a notebook. A file binder is an instrument that binds a paper sheet by passing a plurality of rings through a plurality of holes provided at the end of the paper sheet. The plurality of rings can be opened and closed, and once closed, the closed state is maintained. For this reason, the file binder holds the paper sheet in a replaceable manner, and once replaced, the file binder can be stored for a long time like a book or a notebook. Thus, the file binder has been widely regarded as a file application exclusively because of its characteristics. The binder 101 with magnet pays attention to the characteristic of a file binder, and changes the said file binder into the wall surface holding use of the paper sheet 51 exceeding the conventional common sense. Furthermore, the shape of the ring 22 having the inclined straight portions 28 and 29 is unique to the binder 101 with magnet, and is unnecessary for conventional file applications. That is, the conventional shape that the file binder is used for a file cannot be derived from the shape of the ring 22.

(Embodiment 2)
8A and 8B are perspective views showing the configuration of the binder with magnet according to the second embodiment of the present invention. FIG. 8A shows the front side of the binder with magnet, and FIG. 8B shows the back side. . Moreover, FIG. 9 is sectional drawing of the said binder with a magnet along the DD cut line of FIG.8 (b). This binder 102 with a magnet has the base 6, the ring binder 2, and the magnet 3 as a basic component similarly to the binder 101 with a magnet by Embodiment 1 of this invention. The binder with magnet 102 also corresponds to an embodiment of the magnet holder of the present invention. The base 6 has a region on the upper side of the ring binder 2 when the binder 102 with magnet is held on a magnetic wall (not shown) so as to maintain the original posture shown in FIG. It is wider than the base 1 which the binder 101 with a magnet has. A punch mechanism 4 is fixed on the surface of the widened region so as to be aligned with the ring binder 2. The punch mechanism 4 is a punching mechanism that forms punch holes in the paper sheet in the same number and the same interval as the pair of rings 22 of the ring binder 2, that is, a punching mechanism.

  By using the punch mechanism 4, punch holes are formed on the paper sheet (not shown) to be suspended from the pair of rings 22 of the magnet-attached binder 102 held on the magnetic material wall, and the pair of rings are immediately formed. It can be suspended. That is, there is no need to search for an independent punching machine placed on a desk or the like. In the original use posture, the ring binder 2 is positioned below the punch mechanism 4, so that the paper sheet can be suspended from the pair of rings 22 without being affected by the punch mechanism 4. Further, in addition to the binder 102 with magnet, when the binder 101 with magnet according to the first embodiment of the present invention is held at another place on the magnetic body wall, a paper sheet is suspended from the binder 101 with magnet. Sometimes, the punch hole can be made by using the punch mechanism 4 of the binder 102 with magnet held on the magnetic body wall. That is, by using the binder 102 with magnet as a master unit and the binder 101 with magnet as a slave unit, the punch mechanism 4 included in the binder 102 with magnet can be used effectively.

  The punch mechanism 4 includes a pedestal 41, a handle support 42, a handle 43, and a pair of punch bars 48 as main elements. The pedestal portion 41 has a shape like a lid, and is fixed to the surface of the base 6 so as to cover the surface of the base 6 and form a cavity 40 therein. The cavity 40 functions as a storage space for storing punch scraps 96. The base 6 is formed with a discharge port 61 that communicates with the cavity 40 and discharges punch scraps 96. The discharge port 61 is formed as a through hole that penetrates the base 6 from the front surface to the back surface. The discharge port 61 is formed so as to be positioned on the upper end or near the upper end of the cavity 40 in the original use posture, that is, on the side far from the ring binder 2 so that the punch scraps 96 do not leak unnecessarily. In FIG. 9, the outlet 61 that does not appear on the cut surface along the cutting line DD is also drawn for convenience.

  The handle support portion 42 is fixed to the pedestal portion 41 by being caulked so as to form caulking holes 47 at a plurality of locations of the pedestal portion 41. In other words, the caulking 45 is inserted and caulked through the through holes 46 provided at a plurality of locations of the pedestal portion 41 and through holes 65 provided at the corresponding portions of the handle support portion 42. As a result, the handle support portion 42 is fastened to the pedestal portion 41. As a result, caulking holes 47 are formed in a plurality of fastening portions between the base portion 41 and the handle support portion 42. A through hole 64 is formed in the portion of the base portion 6 corresponding to the caulking hole 47. The pedestal 6 is fixed to the base 6 by inserting, for example, a screw 44 into each of the plurality of caulking holes 47 and the through holes 64 and screwing and tightening a nut 94 to the tip thereof.

  The handle 43 is rotatably attached to the handle support portion 42. As the handle 43 rotates, the handle 43 enters and retracts into a pair of through holes 91 formed in the handle support portion 42 and a pair of through holes 49 formed in the corresponding pedestal portion 41. A pair of possible punch bars 48 are connected. The distance between the pair of punch bars 48 matches the distance between the pair of rings 22 of the ring binder 2. As the pair of punch bars 48 advance and retract through the through holes 49 and 91, punch holes can be formed in the paper sheet inserted in the gap 95 formed between the pedestal portion 41 and the handle support portion 42. . The handle 43 is urged by an elastic member (not shown) such as a spring so that the position where the pair of punch bars 48 are retracted from the through holes 49 and 91 is a standby position.

  As described above, the punch mechanism 4 used for the binder 102 with magnet has the same structure as a conventionally known punch machine. That is, the binder 102 with a magnet enables diversion of a conventionally known punching machine. Thereby, the cavity 40 which accommodates punch scraps can be easily formed between the pedestal 41 and the base 6 of the conventionally known punching machine. Further, the base 6 is fixed to the base 6 by fastening through a fastening member such as a screw 44 to a plurality of caulking holes 47 of a conventionally known punching machine and a through hole 64 formed in the base 6. Can do.

  FIG. 10 is a perspective view showing a usage example of the binder 102 with magnet. A plurality of paper sheets 51 that are, for example, calendars or memo papers are suspended from a pair of rings 22 of the binder 102 with magnet held on the magnetic wall (not shown). A writing instrument 52 such as a pencil is placed on the pair of rings 22. The scale 11 is convenient for determining the center position of one side of the paper sheet 51 in order to open a punch hole at the correct position of the paper sheet 51. In order to be more suitable for this purpose, the scale is determined so that one end of the base 6 becomes the starting point “0 (zero)” of the scale. That is, the scale is formed so as to cover the entire side of the base 6 without providing a margin at both ends. The writing tool 52 placed on the pair of rings 22 is convenient for marking the center position specified by the scale 11. By aligning the center position of one side of the paper sheet 51 marked with the writing tool 52 with, for example, a center position mark embossed on the base 41 of the punch mechanism 4 (illustrated as a triangular mark in FIG. 10), A punch hole can be formed at the correct position of the paper sheet 51. Suspension straps 53 are attached to a pair of suspension holes 12 formed near the upper end of the base 6 and near both left and right ends. This string 53 makes it possible to use the binder 102 with magnet suspended from a magnetic wall as well as a normal wall.

(Other embodiments)
(1) FIG. 11 is an external perspective view illustrating the shape of a magnet that can be used in the binder with magnet of the present invention. FIG. 11A illustrates the magnet 3 used in the binder 101 with magnet of the first embodiment and the binder 102 with magnet of the second embodiment. The magnet 8 illustrated in FIG. 11B is formed in a long rectangular plate shape like the magnet 3. However, the receding portion 81 formed at the edge in the long side direction on the back surface of the magnet 8 is formed in a step shape instead of a slope. A magnet 97 illustrated in FIG. 11C is formed in a circular plate shape, and a receding portion 82 is formed over the entire circumference of the back surface thereof. In the example of FIG. 11C, the receding portion 82 is formed in a conical surface shape whose diameter decreases as it approaches the back surface. As an example, a circular opening is formed in the base, and protrusions 16 and grooves 7 are formed in two locations that are centrally symmetric among the opening edge on the surface side of the base, and the opening edge on the back side of the base By providing a projecting portion similar to the projecting portion 18 over the entire circumference, the magnet 97 can be held in the opening. The magnet 97 is particularly suitable for an application in which the base held on the magnetic body wall 5 by the magnetic force of the magnet 97 does not interfere with the rotation around the magnet 97, or an application in which it is desirable to rotate the magnet 97. . The magnet 403 illustrated in FIG. 11D is formed in a long rectangular plate shape like the magnet 3. However, not only the sloped receding part 431 is formed at the edge in the long side direction of the back surface of the magnet 403 but also the sloped receding part 432 is formed on the surface. This magnet 403 is particularly suitable for use in a magnet holder 112 described later.

  (2) FIG. 12 is a partial sectional view of a binder with magnet according to another embodiment of the present invention, and corresponds to FIG. The binder 103 with magnet is different from the base 1 and the magnet 3 shown in FIG. 3 in the shape of the opening 73 formed in the base 7 and the shape of the magnet 8. The magnet 8 is the magnet 8 illustrated in FIG. 11B, and the retreating portion 81 is formed in a step shape. The overhanging portion 78 formed at the edge in the long side direction on the back surface side of the long rectangular opening 73 is formed in a step shape corresponding to the shape of the receding portion 81 of the magnet 8. Also in this binder 103 with a magnet, since the retreat part 81 is formed in the magnet 8, the thick magnet 8 can be accommodated in the opening part 73. FIG. Furthermore, the back surface of the magnet 8 can protrude somewhat outward from the back surface of the base 7. In addition, the binder 103 with a magnet corresponds also to one Embodiment of the magnet holder of this invention.

  (3) FIG. 13 is a partial cross-sectional view showing a binder with magnets according to two further embodiments of the present invention. FIGS. 13 (a) and 13 (b) both show the binder 101 with magnets. This corresponds to FIG. In the binder 104 with magnet shown in FIG. 13A, the protruding portion 16 formed at the long-side end edge on the surface side of the long rectangular opening 213 of the base 201 is upward from the main surface on the front side of the base 201. It differs from the binder 101 with a magnet by the point which does not protrude. The groove 217 formed behind the projecting portion 16 when viewed from the opening 213 is formed so that the connecting portion 293 supporting the projecting portion 16 has a depth enough to bend toward the groove 293. The binder 105 with magnet shown in FIG. 13B is located behind the projecting portion 15 which is one of the projecting portions 16 and 15 formed on the edge in the long side direction on the surface side of the long rectangular opening 214 of the base 202. Is different from the magnet-attached binder 104 shown in FIG. 13A in that the groove 217 is not formed. If the other protrusion 16 can be sufficiently retracted in the direction of the groove 217, the groove 217 does not need to be formed in two places as illustrated in FIG. In addition, both the binders 104 and 105 with a magnet correspond also to one Embodiment of the magnet holder of this invention.

  Various detent members other than the forms illustrated in FIGS. 3 and 13 can be employed. For example, the connecting portions 93 and 293 that support the protruding portion 16 may be connected to the bases 1, 6, 7, and 202 through side surfaces instead of the bottom surfaces. Further, the protrusions 15 and 16 are arranged at various parts such as three or four in addition to the two parts opposed to each other among the edges of the openings 13, 73, 213, and 214. It is also possible to adopt. For example, when arranged in three places, one of them can be a fixed protrusion 15 and the other two can be movable protrusions 16, or all three can be protrusions 16. .

  (4) FIG. 14 is a process diagram showing a process of inserting the magnet 3 into the opening 214 of the base 202 in the process of manufacturing the binder 105 with magnet shown in FIG. In order to insert the magnet 3 into the opening 214, first, one of the long side end portions of the magnet 3 is inserted between the protruding portion 15 and the overhanging portion 18 as shown in FIG. Next, as shown in FIG. 14B, by pushing down the other end of the magnet 3, the other protrusion 16 is pushed open toward the groove 217. Thereby, the other end of the magnet 3 is placed on the overhanging portion 18 positioned below the protruding portion 16 through the protruding portion 16. As a result, the magnet 3 is accommodated in the opening 214. As shown in FIG. 5C, when the magnet 3 is accommodated in the opening 214, the protruding portion 16 that has been retracted toward the groove 217 returns to the original position by the elastic restoring force of the connecting portion 293. Return. As a result, the magnet 3 is supported without coming out of the opening 214 in either the front or back direction.

  (5) FIG. 15 is a diagram showing a configuration of a magnet holding base and a magnet holder according to another embodiment of the present invention. The magnet holding base 106 illustrated in FIG. 15A is a plate-like body made of, for example, a resin, and has an opening 13, similarly to the base 1 of the magnet-attached binder 101 according to the first embodiment. ing. The openings 13 are formed at the four corners. Similarly to the opening 13 included in the magnet-attached binder 101 according to the first embodiment, the opening 13 has a groove 17 and an overhanging portion 18 (see FIGS. 15A to 15D) in addition to the protruding portion 16. Is not shown). For example, by attaching the magnet 3 illustrated in FIG. 11A to the opening 13, the magnet holding base 106 can be used as a magnet holder. The magnet holding base 106 is, for example, the size of a business card or a bank card. Since the magnet 3 can be accommodated in the opening 13, the thickness does not change even after the magnet is mounted, and can be suppressed to a thickness of, for example, several mm. For example, the magnet holding base 106 can be used in such a manner that a large number of displays displaying various information are prepared, and the magnet 3 is attached to what should be posted and posted on the magnetic body wall. . As a form of displaying information, for example, characters such as name and affiliation are described on the magnet holding base 106, the color of the magnet holding base 106 is changed variously, and the shape of the magnet holding base 106 is changed variously. It can take the form of changing.

  A magnet holder 107 illustrated in FIG. 15B includes a magnet holding base (hereinafter simply referred to as “base”) 9 and a magnet 3 attached to the base 9. Similarly to the base 1, the base 9 is made of, for example, resin, and has an opening 13 that accommodates the magnet 3. The base 9 has a band plate shape, and the openings 13 are formed in the vicinity of both ends in the longitudinal direction of the base 9. The long side direction of the long rectangular opening 13 is along the longitudinal direction of the strip-like base 9. On the surface side of the base 9, a projecting portion 16 is provided at the end of the long rectangular opening 13 in the long side direction. As with the binder 101 with magnet, it is possible that the back surface of the magnet 3 protrudes somewhat outward from the back surface of the base 9, that is, the back surface side of the magnet 3 can cue from the back surface of the base 9. The magnet holder 107 configured as described above can be used as a so-called magnet bar that presses and stops a paper sheet or the like against a magnetic body wall by a magnetic force.

  In the magnet holder 107, the openings 13 can be formed not only at two locations on the base 9, but also at three or more locations. For example, it is possible to form a group of the openings 13 so as to form a row such as four or eight along the longitudinal direction of the base 9. A series of magnetic holders 107 having different attractive forces are prepared as a product lineup by using the common base 9 by changing the number of the openings 13 for holding the magnets 3 among the many openings 13. It is also possible. Further, as already described, if no fixing means other than the protruding portion 16 is used, such as bonding with an adhesive, the opening portion can be opened by retreating the protruding portion 16 with a finger so as to widen the entrance of the opening portion 13. 13 can be removed. In this way, since the magnet 3 can be detachably attached to the opening 13, by attaching the magnet 3 to a thing selected from a large number of openings 13 as required by the user, It is also possible to use the magnet holder 107 for use. For example, the number of magnets 3 can be adjusted in accordance with the thickness of the paper sheet to be held against the magnetic wall with the magnet holder 107. Even in the binders 104 and 105 with magnets having the protruding portions 15 and the protruding portions 16, the magnet 3 can be attached and detached without using other fixing means such as adhesion.

  A magnet holder 108 illustrated in FIG. 15C includes a base 99, a magnet 3 attached to the base 99, and a clip 98 attached to the base 99. Similarly to the base 1, the base 99 is made of resin, for example, and has an opening 13 that accommodates the magnet 3. On the surface side of the base 99 to which the clip 98 is attached, a protruding portion 16 is provided at the edge in the long side direction of the long rectangular opening 13. Similar to the binder 101 with magnet, the back surface of the magnet 3 can protrude somewhat outward from the back surface of the base 99. As illustrated in FIG. 15C, the opening 13 is desirably provided on the upper portion of the base 99 in the original use posture. The clip 98 can be opened and closed by a finger or the like, and is biased to a closed state by an elastic member such as a spring. By using the magnet holder 108 configured as described above, a paper sheet or the like can be held between the clips 98 and held on the magnetic body wall.

  A magnet holder 109 illustrated in FIG. 15D includes a base 90, a magnet 3 attached to the base 90, and a hook 190 attached to the base 90. Similarly to the base 1, the base 90 is made of, for example, resin and has an opening 13 that accommodates the magnet 3. On the surface side of the base 90 to which the hook 190 is attached, a projecting portion 16 is provided at the edge of the long rectangular opening 13 in the long side direction. Similar to the binder 101 with magnet, the back surface of the magnet 3 can protrude somewhat outward from the back surface of the base 90. As illustrated in FIG. 15D, it is desirable that the opening 13 is provided in the upper part of the base 90 as much as possible in the original use posture. By using the magnet holder 109 configured as described above, an accessory or the like can be suspended from the hook 190 and held on the magnetic body wall. Instead of the opening 13, a circular opening may be formed in the base 90, and the circular plate-shaped magnet 97 illustrated in FIG. 11C may be attached to the circular opening.

  (6) FIG. 16 is a partial cross-sectional view of a magnet holder and a binder with a magnet according to still another embodiment of the present invention, and also shows a step of inserting the magnet into the opening of the magnet holding base. . The binder 111 with a magnet has the magnet holder 110 and the ring binder 2 (refer Fig.16 (a) and FIG.16 (f)). The magnet holder 110 has a base 301 having an opening 313 and a permanent magnet 313 held in the opening 313. The ring binder 2 is attached to the surface side of the base 301. The base 301 is formed of, for example, a synthetic resin having appropriate rigidity, like the base 1 (FIG. 1). Unlike the binder 101 with a magnet (refer FIG. 3), the binder 111 with a magnet is formed with the protrusions 315 and 316 instead of the pair of protrusions 16, and the groove 17 is not formed. Although the presentation of the plan view of the magnet holder 110 is omitted, the opening 313 is formed so as to open in a long rectangle like the opening 13 (FIG. 4). Two protrusions 315 and 316 that protrude inward of the opening 313 are formed at the edge in the long side direction on the surface side of the opening 313. In the paper surface of FIG. 16A, the front side and the back side of the protruding portions 315 and 316 are connected to the remaining portion of the base 301. The protrusions 315 and 316 formed in this manner allow the magnet 3 to be inserted into the opening 313 and lock the magnet 3 to prevent the magnet 3 once inserted from returning backward, that is, from falling off to the surface side. To do. That is, the protrusions 315 and 316 correspond to an example of the “detent member” of the present invention.

  In the vicinity of the back surface side of the side wall of the opening 313, overhanging portions 318 and 319 that protrude inward of the opening 313 are formed in the same manner as the overhanging portion 18 of the opening 3 (FIG. 3). The overhang portions 318 and 319 are formed so as to form an inclined surface at the edge in the long side direction of the opening 313. The overhang portions 318 and 319 function as a locking member that locks the magnet 3 in order to prevent the magnet 3 from falling off from the opening portion 313 to the back surface side, similarly to the overhang portion 18 (FIG. 3). A recess 351 is formed on the side wall located at one of the pair of long side edges of the opening 313 by the protrusion 316 and the overhang 318. Similarly, a recess 352 is formed on the side wall located at the other of the pair of long side edges of the opening 313 by the protrusion 315 and the overhang 319. Both of these recesses 351 and 352 are continuously narrower toward the back because of the slopes of the overhang portions 318 and 319. Further, the recess 351 is formed deeper than the recess 352.

  In order to insert the magnet 3 into the opening 313, as shown in FIG. 16B, first, one of the end portions in the long side direction of the magnet 3 is placed between the protruding portion 316 and the overhanging portion 318, that is, the depth. Is inserted into the deeper recess 351. Next, as shown in FIG. 16C, by applying a finger force to the magnet 3, the end of the magnet 3 is pushed into the recess 351. Since the end of the magnet 3 is wedge-shaped for the retreating portion 31 and the recess 351 is continuously narrowed toward the back, the protruding portion 316 and the overhanging portion 318 are elastically deformed. Alternatively, the width of the concave portion 351 is expanded by elastic deformation of any of them. Thereby, the end of the magnet 3 can be inserted into the recess 351, and the end of the magnet 3 opposite to the pushed-in side is allowed to escape from the protrusion 315 so as not to interfere with the protrusion 315. It can be led into 313 (FIG. 16 (d)). As a result, the entire magnet 3 can be inserted into the opening 313. Since the retracted portion 31 is also formed at the end portion of the magnet 3 facing the protruding portion 315, the end portion is thin. This also makes it easy for the magnet 3 to fit in the opening 313 while avoiding interference with the protrusion 315.

  Since the finger force is released after the magnet 3 is inserted into the opening 313, the width of the recess 351 expanded by elastic deformation returns to the original width. As a result, the magnet 3 can no longer pass between the two protrusions 315 and 316 and escape from the opening 313 to the front side of the base 301. Since the concave portion 352 that does not need to be elastically deformed so as to increase the width is formed shallower than the concave portion 351, the base 301 can be easily manufactured. In particular, when the base 301 is formed by molding a resin using a mold, the operation of the mold becomes easy.

  If the base 301 is made of a material having an appropriate rigidity so that the protruding portion 316 or the overhanging portion 318 can be elastically deformed to accept the retracted portion 31 of the magnet 3, as shown in FIG. Thus, the magnet 3 can be easily removed to the front side by applying a bending deformation along the long side direction of the opening 313 with the force of fingers. That is, the base 301 holds the magnet 3 detachably in the opening 313 in the same manner as the base 1 (FIG. 1), etc., if fixing means other than the protrusions 315 and 316, for example, adhesion by an adhesive is not used. To do. As shown in FIG. 16F, when the ring binder 2 is attached to the base 301, the rigidity of the ring binder 2 prevents the base 301 from being bent and deformed. For this reason, it is difficult to remove the magnet 3 from the opening 313 by bending the base 301 with fingers. However, by pressing the magnet 3 against the concave portion 351 while sandwiching the magnet 3 using a certain jig, a process opposite to the insertion process of the magnet 3 is performed (FIGS. 16D to 16D). b)) The magnet 3 can be removed.

  The magnet 3 is accommodated in the opening 313 with a certain amount of play in the direction along the long side of the opening 313 and in the depth direction. This makes it easier to insert the magnet 3 illustrated in FIGS. 16B and 16C into the opening 313. That is, in the process of FIG. 16B and FIG. 16C, the magnet 3 rotates at a certain angle with the end inserted into the recess 351 as an axis. If there is play in the left-right direction and the depth direction between the magnet 3 and the opening 313, this rotation is facilitated, so that the magnet 3 can be easily inserted into the opening 313.

  (7) FIG. 17 is a partial cross-sectional view of a magnet holder according to still another embodiment of the present invention, and also shows a process of inserting the magnet into the opening of the magnet holding base. The magnet holder 112 includes a base 401 having an opening 413 that opens in a long rectangle, and a long rectangular plate-like permanent magnet 403 that is held in the opening 413. As with the base 1 (FIG. 1), the base 401 is formed of, for example, a synthetic resin having appropriate rigidity. The magnet holder 112 is different from the magnet holder 110 (see FIG. 16) in the shapes of the protrusions 416 and 415. That is, the protrusions 416 and 415 are formed so that the width is large at the base and narrows toward the tip. Also in this embodiment, a concave portion 451 is formed by the protruding portion 416 and the protruding portion 418 on the side wall of the opening 413, and a concave portion 352 is formed by the protruding portion 415 and the protruding portion 419. Both of these recesses 451 and 452 are continuously narrower toward the back. Further, the recess 451 is formed deeper than the recess 452.

  The magnet 403 illustrated in FIG. 11D is applied to the opening 413 so as to conform to the shape of the opening 413. The magnet 403 has sloped retreat portions 431 and retreat portions 432 formed at the edges in the long side direction on both the back surface and the front surface. As illustrated in FIGS. 17B to 17E, the magnet 403 is opened by performing a process similar to the process of inserting the magnet 3 illustrated in FIGS. 16B to 16D. It can be inserted into the part 413. That is, by applying a finger force to the magnet 403, the protrusion 416 and the overhanging portion 418 can be elastically deformed, or any one of them can be elastically deformed, so that the width of the concave portion 451 can be expanded. As a result, the end of the magnet 403 can enter the back of the recess 451, and the other end of the magnet 403 can be accommodated in the opening 413 without interfering with the protrusion 415. The protrusions 415 and 416 function as the “detent member” of the present invention, like the protrusions 315 and 316 (FIG. 16). Similarly to the base 301 (FIG. 16E), the base 401 can be easily removed from the front side by applying a bending deformation along the long side direction of the opening 413 with the force of fingers. Is possible. As clearly illustrated in FIG. 17E, the magnet 403 is accommodated in the opening 313 with some play in the direction along the long side of the opening 313 and in the depth direction. This makes it easier to insert the magnet 403 illustrated in FIGS. 17B and 17C into the opening 413.

  (8) The ring binder used in the binder with magnet of the present invention is not limited to the ring binder 2 shown in FIG. For example, the number of rings 22 is not limited to two, and may be generally plural. Further, the closing maintaining mechanism for maintaining the closed state of the ring 22 is not limited to the form illustrated in FIG. As long as it has a plurality of rings that can be opened and closed and has a closed maintenance mechanism that holds the closed state once the plurality of rings are closed, it can be used as a ring binder that the magnet-attached binder of the present invention has. is there.

  (9) In the opening portion 13 illustrated in FIG. 3, the overhang portions 18 are formed at both ends in the long side direction on the back surface side of the opening portion 13. On the other hand, the overhanging portion 18 may be formed over the entire circumference of the edge on the back surface side of the opening 13, and within a range in which the magnet 3 does not fall off from the back surface side, for example, a short portion. Overhangs 18 may be formed at both edges in the side direction. Correspondingly, the retreating portion 31 of the magnet 3 may be formed over the entire circumference of the rear surface side edge, or may be formed in a part of the entire circumference.

  (10) In FIG. 3, a receding portion may be provided on the surface of the magnet 3 at a portion facing the pair of protruding portions 16. Thereby, the magnet 3 can be made thicker. The receding portion may be formed to form a slope like the receding portion 432 of the magnet 403 illustrated in FIG. 11D, for example, and may be formed on the back side of the magnet 8 illustrated in FIG. Similar to the receding portion 81, it may be formed in a stepped shape.

  (11) Instead of the caulking 24 illustrated in FIG. 6, other fastening members such as screws, bolts and nuts may be used. In addition, other fastening members such as caulking can be used instead of the screws 44 shown in FIG. Caulking has the advantage of being inexpensive and easily allowing semi-permanent fixing.

  (12) In the above embodiment, the example in which the punch rods 48 of the punch mechanism 4 are arranged in the same number and at the same intervals as the rings 22 of the ring binder 2 has been described. On the other hand, when the number of the rings 22 of the ring binder 2 is three or more, it is possible to use the punch mechanism 4 in which the punch rods 48 are at the same interval as the rings 22 but less than the number of the rings 22. Is possible. For example, when the number of the rings 22 is 3 and the punch mechanism 4 having two punch rods 48 is used, two punch holes are formed in the paper sheet by one operation of the punch mechanism 4. The third punch hole can be made by operating the punch mechanism 4 again after shifting the paper sheet so that the other punch rod passes through the one punch hole.
