As described above, the moving partition device is used as one that can change the size and shape of the room according to the situation. The moving partition device is configured such that a panel is suspended and supported by a runner that moves in a rail supported by a ceiling via a fixing member. The panel is moved by a person holding the panel, pushing and pulling it, and applying a driving force in the moving direction to the panel. By applying a driving force to the panel, the runner moves along the rail, so that the panel can be moved to a desired position along the rail.

  On the other hand, since the runner moves in the rail in the moving partition device, there is a problem that the vibration generated by the runner is transmitted to the upper floor or the like through the fixing member. In order to solve this problem, some moving partition devices have an anti-vibration mechanism. For example, as such a moving partition device, a spacer is provided between the hanger rail and the fixed member, a flat plate is provided inside the fixed member via a vibration isolator, and the flat plate is brought into pressure contact with the vibration isolator. A technique described in Patent Document 1 below is known. According to this, vibration generated by the partition moving on the hanger rail is transmitted from the hanger rail to the flat plate via the bolt and absorbed by the vibration isolator, or absorbed from the hanger rail via the spacer by the vibration isolator. The transmission of the vibration to the fixing member is reduced.

<Embodiment 1>
Hereinafter, Embodiment 1 according to the present invention will be described with reference to FIGS. In addition, about the component which has the substantially same function in this specification and drawing including Embodiment 1 and Embodiment 2 mentioned later, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

(Device configuration)
First, the structure of the movement partition apparatus which concerns on this Embodiment is demonstrated. As shown in FIG. 1, the moving partition device 1 according to the present embodiment includes a moving partition 10 and a vibration isolator 20. Hereinafter, each structure of the movement partition apparatus 1 is demonstrated in detail.

(Moving partition 10)
The moving partition 10 is fixed to the lower plate 26 of the vibration isolator 20 via a fastener 32 made of bolts and nuts, and a rail 102 on which the edge of the ceiling panel 120 is placed at the lower end thereof, and the rail 102. A runner 104 that can move along the inner wall of the first and second panels 106 is suspended and supported by the runner 104. The rail 102 forms a travel route on which the runner 104 can travel, and the arrangement position of the panel 106, that is, the size and shape of the space partitioned by the panel 106 are determined by the arrangement of the rail 102.

(Vibration isolator 20)
The vibration isolator 20 is attached to the base member 50, which is a lip groove steel having a C-shaped cross section, which is fixed to a hole anchor embedded in a ceiling wall (not shown) or a slab on an upper floor through a suspension bar 40 by welding. Are attached via fasteners 34 made of bolts and nuts, and support the moving partition 10 so as to be horizontally movable and swingable, and to the upper floor of vibration when the runner 104 moves and when it collides with the inner wall of the rail 102. It is a so-called indirect material that reduces transmission of light. Specifically, the vibration isolator 20 is disposed below the upper plate 24, an attachment member 22 that can be detachably attached to the base member 50, an upper plate 24 whose upper surface is in contact with the base member 50, and the upper plate 24. The lower plate 26 and a locking tool 28 that supports the lower plate 26 at a position separated from the upper plate 24 are provided.

(Mounting member 22)
As shown in FIGS. 2 and 3, the mounting member 22 is formed from two sides of a substantially rectangular bottom wall 222 having one corner cut out and a bottom wall 222 orthogonal to each other forming the corner. This is an angle member in which two side walls 224 and 224 erected are integrated. In the present embodiment, two insertion holes 224a and 224a into which the bolts of the fasteners 34 can be inserted are provided along the diagonal lines on the side walls 224 and 224, and the side wall 224 and the side wall of the base member 50 are connected to each other. The attachment member 22 can be fixed to the base member 50 by abutting and inserting and fastening the fastener 34 into the insertion hole 224a. The number of the insertion holes 224a and the positions to be provided are not limited to this, and may be set as appropriate according to the loads of the moving partition 10 and the vibration isolator 20. The bottom wall 222 is formed with an insertion hole (not shown) through which the bolt 282 of the locking tool 28 can be inserted. The upper plate 24 is locked to the mounting member 22 by inserting a bolt 282 of the locking tool 28 into this insertion hole and fastening a nut 284 described later. In addition, it is preferable that the contact surfaces of the attachment member 22 and the upper plate 24 are fixed by welding or an adhesive so as not to move relative to each other.

(Upper plate 24, lower plate 26)
The upper plate 24 is a rectangular flat plate-shaped steel plate whose upper surface (here, substantially central surface) is in contact with the lower surface of the base member 50 and is locked to the mounting member 22 by the locking tool 28 as described above. There are formed through holes (not shown) through which the bolts 282 of the locking tool 28 can be inserted. The lower plate 26 is a box-shaped steel plate (see FIG. 4) that is open at the top of a rectangle and is disposed below the upper plate 24 at a predetermined interval (for example, 30 mm), and has four corners on its bottom wall. An insertion hole (not shown) is formed at a position facing the insertion hole of the upper plate 24 in FIG. Hereinafter, when the upper plate 24 and the lower plate 26 are not distinguished from each other, they will be referred to as “plates”. It is preferable that the insertion hole formed in each of these plates has a diameter larger than the diameter of the bolt 282. The lower plate 26 is provided with a plurality of screw holes (not shown) into which the bolts of the fasteners 32 can be screwed. The upper surface of the rail 102 of the moving partition 10 is in contact with the lower surface of the lower plate 26. The moving partition 10 can be fixed to the lower plate 26 by screwing the bolts of the fasteners 32 to each other.

  As shown in FIG. 4, in a space defined between the upper plate 24 and the lower plate 26, at least at a position located below the base member 50, a sound absorbing material 25 such as glass wool having sound absorbing properties. Is arranged. The sound absorbing material 25 reduces transmission of noise such as vibration noise generated by the runner 104 in the rail 102 to the upper floor. In the present embodiment, the lower plate 26 is formed to be slightly larger than the upper plate 24, but may have the same shape as the upper plate 24 or a smaller shape.

(Locking tool 28)
As shown in FIG. 2, the locking tools 28 are disposed at the four corners of the vibration isolator 20 to lock the lower plate 26 with respect to the upper plate 24, and a predetermined amount of the upper plate 24 and the lower plate 26. It is a so-called regulating member that prevents the above separation. As shown in FIGS. 1, 3, and 4, the locking member 28 is inserted through the insertion holes of the attachment member 22, the upper plate 24, and the lower plate 26. A bolt 282, a nut 284 that can be screwed onto the bolt, and a hollow cylindrical coil spring 286 disposed between the upper plate 24 and the lower plate 26 are configured.

  Specifically, the locking tool 28 inserts the bolt 282 into each insertion hole from the upper surface of the upper plate 24, and the bolt 282 from the opposite surface (here, the lower surface) of the lower plate 26 facing the upper plate 24. The nut 284 is fastened and disposed. Thereby, the locking tool 28 prevents the upper plate 24 and the lower plate 26 from being separated by a predetermined amount or more, that is, the lower plate 26 cannot be moved downward, and the lower plate 26 is moved away from the upper plate 24. It can be locked in such a manner that it can move upward within the distance, move horizontally in the distance between the insertion hole of the lower plate 26 and the bolt 282, and tilt. In addition, according to this locking tool 28, when adjusting the space | interval which leaves | separates, since it is only necessary to rotate the nut 284 so that it may advance or retract along the volt | bolt 282, the increase in the amount of the sound-absorbing material 25 and the addition of a soundproof material are sufficient. Such operations can be performed by a simple method.

  Further, the head 282a and the nut 284 of the bolt 282 have a larger diameter than the insertion holes formed in the mounting member 22 and each plate, and the contact surfaces 282b and 284b that contact the mounting member 22 and the lower plate 26 are spherical surfaces (curved surfaces). ) It has a shape. As a result, the peripheral edges of the insertion holes of the mounting member 22 and the lower plate 26 facing the head 282a and the nut 284 and the contact surfaces 282b and 284b come into line contact, and the head 282a and the nut 284 are slid against the peripheral edge. It is possible to move. Therefore, the locking tool 28 itself can swing with respect to each plate, and a displacement such as upward movement, horizontal movement, and rocking of the lower plate 26 in a wider range is realized.

  The coil spring 286 is disposed between the upper plate 24 and the lower plate 26 in a state of being wound around the bolt 282, and the plates are respectively separated from the inner side (sides on which the plates face each other). Energized. In addition to preventing displacement of the coil spring 286 itself, the biasing can absorb the vibration of the moving partition 10 including the displacement of the lower plate 26 and push the displaced lower plate 26 back downward. Note that the coil spring 286 does not necessarily have to be wound around the bolt 282 and may be disposed in or around the sound absorbing material 25. However, by arranging the coil spring 286 around the bolt 282, the coil spring 286 itself can be prevented from moving or dropping in the horizontal direction, and the coil spring 286 is attached at the same time when the locking tool 28 is attached. Therefore, the construction is also easy. In addition, it is not limited to the coil spring 286, You may use instead the elastic body which show | plays the effect similar to a coil spring, such as a leaf | plate spring and a rubber material.

  With these bolts 282, nuts 284, and coil springs 286, the locking tool 28 is moved from the stable state in which no external force is applied to the moving partition 10 as shown in FIG. 5 (a) to FIG. 5 (b). As shown, even when an external force is applied and the lower plate 26 is tilted, the contact surfaces 282b and 284b of the head 282a and the nut 284, particularly the contact surfaces 282b of the head 282a, are spherical. The locking tool 28 itself can tilt according to the tilt. Further, the coil spring 286 is compressed in accordance with the inclination of the lower plate 26 to absorb the stress, and the lower plate 26 can be pushed back by the restoring force. When the lower plate 26 is pushed back, the contact surfaces 282b and 284b have a spherical shape, so that the peripheral edge of the insertion hole of the mounting member 22 and the lower plate 26 is also slid on the spherical surface. It is possible to return to a stable state.

  Since the contact surfaces 282b and 284b of the bolt 282 and the nut 284 are in line contact with the peripheral edges of the insertion holes of the mounting member 22 and the lower plate 26, a load is applied to the contact portion. Therefore, when the locking tool 28 tilts, the contact surfaces 282b and 284b slide with respect to the periphery of the insertion hole. Further, when the lower plate 26 is pushed upward by the movement of the movement partition 10, the lower plate 26 and the nut 284 collide with each other by being pushed back downward by the restoring force of the coil spring 286. In such a case, since the attachment member 22 and the lower plate 26 according to the present embodiment are metal members, there is a possibility that a metal sound is generated due to the contact or collision. Therefore, as shown in FIG. 6A, the peripheral edge of the insertion hole that contacts the head 282a and the nut 284 of the bolt 282, that is, the contact surfaces 282b and 284b of the bottom wall 222 of the mounting member 22 and the lower plate 26. It is preferable to process the peripheral edge of each insertion hole in contact with the taper. Further, the contact surfaces 282b and 284b may be brought into surface contact by curving a tapered surface corresponding to the spherical shape. By processing in this way, it is possible to disperse the load applied to the contact surfaces 282b and 284b and reduce the metal sound generated by the contact.

  Further, as shown in FIG. 6 (b), cushioning materials 282c and 284c are provided on the contact surfaces 282b and 284b, the contact surfaces 282b and 284b of the head 282a and the nut 284, the mounting member 22 and the lower plate 26. You may make it prevent the contact itself with the periphery of each insertion hole. Thereby, generation | occurrence | production of the said metallic sound can be prevented. The buffer materials 282c and 284c may be provided not only on the contact surfaces 282b and 284b but also on the periphery of the insertion hole, or on the inner wall surface of the insertion hole or the bolt 282. Further, the taper processing and the cushioning materials 282c and 284c may be used in combination.

  Next, the function of the movement partition device 1 according to the present embodiment will be described more specifically with reference to FIGS. For the sake of explanation, the lower plate 26 in FIGS. 7 and 8 is shown in cross section. According to the moving partition device 1 including the vibration isolator 20 having the above-described configuration, for example, as illustrated in FIG. 7, the moving partition 10 is in the horizontal direction (the direction perpendicular to the horizontal direction with respect to the moving direction of the runner 104: Since the lower plate 26 is locked so as to be movable upward as described above when it swings in the right direction as viewed in the drawing, the end of the lower plate 26 on the right side of the figure is moved upward according to the swing. Can be displaced. At this time, the stress is applied to the coil spring 286, and the coil spring 286 is compressed accordingly to be attenuated, and the swing of the lower plate 26 is absorbed. Thereby, the oscillation is not transmitted to the upper plate 24, and the transmission of the vibration caused by the oscillation to the upper floor can be reduced.

  Further, as shown in FIG. 8, when the movement partition 10 is translated in the horizontal direction, the lower plate 26 is locked so as to be movable in the horizontal direction as described above, and the bolts of the locking tool 28. Since the contact surfaces 282b and 284b of the head 282a of the 282 and the nut 284 are spherical, the locking tool 28 can be tilted and displaced laterally in accordance with the parallel movement. At this time, the stress is applied to the coil spring 286, and the coil spring 286 is accordingly displaced in the lateral direction to be attenuated, and the lateral displacement of the lower plate 26 is absorbed. Thereby, the said parallel movement is not transmitted to the upper plate 24, and it can reduce that the vibration resulting from this transmits to an upper floor. After the lower plate 26 is displaced as shown in FIGS. 7 and 8, as described above, due to the spherical shape of the contact surfaces 282b and 284b of the head 282a and the nut 284 and the restoring force of the coil spring 286, The swing-back function works to return the lower plate 26 to the original stable position.

  Further, in the vibration isolator 20, since the mounting member 22 has two side walls 224 and 224, the rail 102 arranged along the base member 50 is connected in an F shape as shown in FIG. Even if it is the case, the side wall 224 is made to contact | abut to the side wall of the base member 50 irrespective of connection structures, such as each linear part 102a, the joint part 102b, the L-shaped part 102c, and the T-shaped part 102d. Can be installed easily. As shown in FIG. 10, the same applies to a portion where the rails 102 arranged along the base member 50 are connected in a cross shape and a cross portion 102e is formed. Moreover, although the arrangement | positioning space | interval of the vibration isolator 20 is appropriate, it is preferable to provide at intervals shorter than the length of the panel 106 in the longitudinal direction.

  As described above, according to the present embodiment, transmission of displacement of the moving partition 10 to the upper floor including vibration generated when the runner 104 of the moving partition 10 collides with the inner wall of the rail 102 is reduced. Can do. Further, the vibration isolator 20 includes a mounting member 22, an upper plate 24, a lower plate 26, and a locking tool 28 and is unitized. Therefore, it is only necessary to arrange an appropriate number of the vibration isolator 20 between the base member 50 and the rail 102 of the moving partition 10, the construction is easy, and the connection structure of the base member 50 and the moving partition 10 is achieved. It can be installed accordingly. Moreover, since the vibration isolator 20 is comprised from the attachment member 22, the upper plate 24, the lower plate 26, and the latching tool 28, it is cheap and highly durable. Furthermore, when the housing shakes due to an earthquake or the like, it is possible to reduce the load on the moving partition 10, particularly the rail 102 and the runner 104, transmitted through the base member 50.

  In the present embodiment, the contact surfaces 282b and 284b of both the head 282a and the nut 284 of the bolt 282 are spherical, but only the contact surface 282b of the head 282a may be spherical. Further, the coil spring may be fixed to the upper plate 24 and the lower plate 26 without using the locking tool 28. In such a case, since the load of the moving partition 10 is applied only to the coil spring, an adverse effect such as deterioration of the restoring force of the coil spring occurs, but the effect of improving vibration isolation and ease of construction can be realized.

(Application examples)
With respect to the moving partition device 1 according to the present embodiment, by providing the roller cushioning material and the support shaft cushioning material according to the inventors' invention in the rail 102, the effects of vibration and sound insulation can be further improved. . FIG. 11 shows a moving partition device 1 ′ provided with these roller cushioning material and support shaft cushioning material. Specifically, the moving partitioning device 1 ′ faces the peripheral surface of the roller 104 a of the runner 104 on the inner wall of the rail 102. A recess is provided at a location, and a roller cushioning material 62, which is an elastic body that cushions the impact caused by the contact and the impact sound when the roller 104a contacts, is fitted into the recess. On the other hand, a recess is provided in the rib of the rail 102 at a location facing the peripheral surface of the support shaft 104b of the runner 104. When the support shaft 104b comes into contact with this recess, the impact caused by the contact and the impact sound thereof. A support shaft cushioning material 64, which is an elastic body that cushions, is fitted.

  According to the moving partition device 1 ′ having such a configuration, the impact and sound caused by the contact between the roller 104 a of the runner 104 and the support shaft 104 b with respect to the rail 102 can be mitigated by the roller cushioning material 62 and the support shaft cushioning material 64. Since the vibration and noise can be further reduced by the vibration isolator 20, vibration and noise transmission to the upper floor can be more reliably reduced.

(Example)
In order to ensure the effectiveness of the vibration isolation (seismic resistance) of the moving partition device 1 according to the present embodiment, the moving partition device 1 and the comparison in which the moving partition 10 is directly fixed to the base member 50 without providing the vibration isolating device 20. A vibration test was performed by comparing with the target moving partition device. As test conditions, the rails 102 are connected in an F shape along the base member 50 arranged as shown in FIG. 12, and vibration meters A to D, which are measuring instruments capable of measuring vibration, are arranged on the rail 102. did. Specifically, the vibrometer A is disposed directly on the lower surface of the base member 50, and the vibrometer B is disposed on the side surface of the secondary base member that is disposed above the base member 50 and supports the base member 50. Moreover, the vibrometer C was disposed on the convex surface of the deck plate of the slab that supports the base member 50, and the vibrometer D was disposed on the lower surface of the L-shaped angle, which is a suspension material constituting the upper floor. Therefore, it can be said that the moving partition device 1 is effective if the vibration reducing effect derived from the measurement result of the vibration meter D closest to the upper floor is high. As shown in FIG. 12, the moving partition device 1 is provided with an anti-vibration device 20 at a key point, and the moving partition device to be compared is a base member without the anti-vibration device 20 being provided. The rail 102 was fixed to 50.

  Under the above-mentioned conditions, the panel 106 was moved together with the runner 104, and acceleration measurement with each vibrometer was performed five times. The measurement results are shown in FIG. “None” shown in FIG. 13 indicates the measurement result of the comparison moving partition device that does not include the vibration isolator 20, and “Yes” indicates the measurement result of the movement partition device 1. As shown in this, it can be seen from the measurement results of the vibration meters A to D that the vibration isolator 20 is uniformly provided has a vibration reducing effect. In particular, the effect of reducing the vibration meter D appears remarkably. From the above, it can be seen that by providing the vibration isolator 20, the moving partition device 1 has extremely high vibration isolation and earthquake resistance.

<Embodiment 2>
Hereinafter, Embodiment 2 according to the present invention will be described with reference to FIGS. The moving partition device according to the present embodiment has an anti-vibration device 20 ′ having a different structure instead of the anti-vibration device 20 as compared with the moving partition device 1 described in the first embodiment.

(Vibration isolation device 20 ')
As shown in FIGS. 14 and 15, the vibration isolator 20 ′ included in the moving partition device according to the present embodiment includes an attachment member 22 ′ that can be detachably attached to a base member (not shown), and an attachment member 22 ′. The lower plate 26 'disposed below the lower plate 26, and a locking member 28 for supporting the lower plate 26' at a position spaced from the mounting member 22 '. Therefore, as compared with the vibration isolator 20 of the moving partition device 1 in the first embodiment described above, the vibration isolator 20 ′ is provided with the attachment member 22 ′ instead of the attachment member 22, and the lower plate 26 ′ instead of the lower plate 26. Each has.

(Mounting member 22 ')
The attachment member 22 ′ is an integration of the attachment member 22 and the upper plate 24 described in the first embodiment, and an upper plate formed with an insertion hole (not shown) through which the bolt 282 of the locking tool 28 can be inserted. The rectangular bottom wall 222, a side wall 226a standing substantially perpendicular to one side of the bottom wall 222, and extending parallel to the bottom wall 222 from the upper end of the side wall 226a toward the opposing mounting member 22 ′ This is a so-called crank-shaped angle member formed integrally with the upper wall 226b. A protruding piece 226c that protrudes downward is formed at the end of the upper wall 226b, and a locking portion 226 that can be locked to the base member is formed by the side wall 226a, the upper wall 226b, and the protruding piece 226c. . Specifically, the locking portion 226 can be in a state in which the protruding piece 226c is caught by the groove edge formed on the upper portion of the base member by the side wall 226a and the upper wall 226b coming into contact with the base member. It can be locked to the member so as to cover a part of the member.

  Further, in the present embodiment, one mounting member 22 ′ is disposed corresponding to one locking tool 28, and the coil spring 286 of the locking tool 28 directly contacts the back surface of the bottom wall 222. Has been. As a result, the mounting member 22 ′ can swing around the locking tool 28, and even when the mounting member 22 swings, the restoring force of the coil spring 286 functions to return and the original stable state can be achieved. It is possible to return to a position (for example, the position shown in FIG. 14). Therefore, the vibration isolator 20 ′ can have a vibration isolating function equivalent to that of the vibration isolator 20. Further, since the bottom wall 222 of the mounting member 22 ′ is not immovably fixed to any element of the locking member 28, the mounting member 22 ′ itself is not attached to the lower plate 26 ′ as shown in FIG. Thus, the relative rotation is possible, and the direction of the locking portion 226 can be made variable.

  The side wall 226a of the locking portion 226 is provided with four insertion holes 226d through which the bolts of the fastener 34 can be inserted. The side wall 226a and the side wall of the base member are in contact with each other, and are fastened to the insertion hole 226d. When the tool 34 is inserted and fastened, the attachment member 22 ′ can be fixed to the base member so as not to move. The number and positions of the insertion holes 226d are not limited to this, and may be set as appropriate according to a moving partition (not shown) or the load of the vibration isolator 20 '.

  Further, as shown in FIG. 17, the edge of the insertion hole formed in the bottom wall 222 of the mounting member 22 ′, specifically, the bolt 282 of the locking tool 28 and the portion that comes into contact with the head 282a, It is preferable to perform burring so as to fall downward and be positioned within the diameter of the coil spring 286. Further, it is more preferable that the surface of the locking tool 28 that directly contacts the bolt 282 and its head 282a is tapered or curved. By performing such processing, it is possible to improve the followability of the bolt 282 and to prevent the rampage including the displacement of the coil spring 286 and the like.

  This burring process is preferably performed on an insertion hole (not shown) facing the insertion hole of the bottom wall 222 of the mounting member 22 ′ in the lower plate 26 ′. The lower plate 26 ′ has the same configuration as that of the lower plate 26 described in the first embodiment except that the insertion hole is subjected to burring, and therefore the details thereof are omitted.

  A method of attaching the vibration isolator 20 'to the base member will be described with reference to FIGS. First, after the vibration isolator 20 ′ is brought close to the base member 50, as shown in FIG. 18, the direction in which one of the two attachment members 22 ′ positioned on the left and right sides of the base member 50 is separated from each other. And the locking portion 226 is hooked on one side of the groove edge of the base member 50. Next, the other mounting member 22 ′ is similarly swung and hooked on the other side of the groove edge, so that the vibration isolator 20 ′ can be easily locked to the base member 50. At this time, each of the locking portions 226 abuts against the side wall surface and the upper wall surface of the base member 50, and the protruding pieces 226 c are respectively caught on the edges of the upper walls, so that the base member 50 is firmly locked. Therefore, the vibration isolator 20 ′ is not easily dropped. After the vibration isolator 20 ′ is locked to the base member 50, as shown in FIG. 19, the fastener 34 is inserted into each insertion hole 226d of the attachment member 22 ′ and fastened, whereby the base member 50 is fixed. On the other hand, the vibration isolator 20 ′ can be fixed so as not to move through the mounting member 22 ′.

  According to the present embodiment described above, by providing the locking portion 226 on the mounting member 22 ′, the vibration isolator 20 ′ can be easily locked to the base member 50 while having a vibration isolation function. be able to. Thereby, since the base member 50 and the attachment member 22 'can be easily fastened by the fastener 34, the workability when attaching the vibration isolator 20' can be remarkably improved.

  Further, as described above, the attachment member 22 'is provided to be rotatable relative to the lower plate 26'. Therefore, as shown in FIG. 20, the base member 50 as shown in FIG. 21 is assembled in a T shape as well as the locking portion 226 can be locked to the linear base member 50. Even if it is a case, the attaching part 22 'can be rotated and the direction of the latching | locking part 226 can be changed, and the latching | locking part 226 can be latched to the coupling | bond part suitably. This change in direction of the locking portion 226 prevents the locking portion 226 from being locked by a structure, such as a hanging bar 40 (see FIGS. 18 and 19) provided on one base member 50 of the coupling portion. This is particularly effective when the mounting member 22 ′ only needs to be rotated so that the locking portion 226 faces the other base member 50 that does not interfere with the hanging bar 40, and extremely versatility is realized. Needless to say, this is the same even if the connecting portion has a shape other than the T-shape, such as a cross.

  In the present embodiment, the attachment member 22 ′ is formed in a crank shape, but is not limited to this. The side wall 226a of the mounting member 22 ′ is provided on the opposite side of the bottom wall 222, and the upper wall 226b is further increased to form a substantially U shape. The locking portion 226 does not contact the side surface of the base member 50. You may make it contact | abut only to an upper surface. In this case, the insertion hole 226d may be formed in the upper wall 226b. Further, the mounting member 22 ′ is provided with a protruding piece 226 c, but this is removed, and the locking portion 226 is locked only by contact between the upper wall 226 b of the mounting member 22 ′ and the upper surface of the base member 50. You may do it. In this case, it is temporarily locked, but if the insertion hole 226d is provided in the upper wall 226b, it can be fastened by the fastener 34.
