  An object of the present invention is to prevent the visibility of a posted pattern or the like written on the surface of the sheet from being significantly reduced by suppressing the sheet from being bent and deformed.

  In the present application, a posting pattern (hereinafter referred to as a posting pattern or the like) is described on one surface of the sheet (3), and further, a posting pattern or the like is described on the sheet (3). It is wound around the drum (5) so that the front surface faces the outer peripheral side from the back surface on which the posting pattern or the like is not described.

Here, “posted pattern etc.” means not only so-called patterns such as ○ and Δ, but also patterns having an information transmission function such as characters.
By the way, when the sheet (3) is wound around the drum (5), the sheet generally tends to bend and deform so that the surface on the drum (5) side is recessed. And if a sheet | seat (3) bends so that the surface side may be dented, there exists a possibility that visibility, such as a posting pattern described on the surface, may fall remarkably.

  On the other hand, in the present application, the sheet (3) is wound around the drum (5) such that the surface on which the posting pattern or the like is described faces the outer peripheral side from the back surface on which the posting pattern or the like is not described. Therefore, the sheet (3) is easily bent and deformed so that the back surface on which the posting pattern or the like is not described is recessed.

  Therefore, in this application, since it can suppress that a sheet | seat (3) will bend and deform | transform so that the surface side may be dented, it can prevent that the visibility of the posting pattern etc. which were described on the surface falls remarkably.

  Note that the surface of the flange portion 5B on the drum main body 5A side is such that the distance W1 between the pair of flange portions 5B increases as the distance from the drum main body 5A increases (radially outward). It is comprised by the taper surface inclined with respect to the direction (radial direction) orthogonal to the direction of L1.

  Further, as shown in FIG. 3, the drum body 5A is provided with an assembly hole 5D in which one end side in the longitudinal direction of the sheet 3 is assembled. The assembly hole 5D extends from the outer peripheral surface of the drum body 5A to the axis L1 (drum 5 is formed in a slit shape extending in the direction of the axis L1.

  Then, the slit width W2 on the outer peripheral side of the assembly hole 5D is set to be smaller than the slit width W3 on the axis L1 side (hereinafter, this portion is referred to as a locking portion 5E of the assembly hole 5D). The slit width refers to an inner diameter dimension in a direction orthogonal to the depression direction of the assembly hole 5D.

  On the other hand, one end in the longitudinal direction of the sheet 3 is provided with an annular part (annular part) 3A which is a part of the sheet 3 folded back as shown in FIG. 7, and the annular part 3A has an outer dimension larger than the slit width W2.

  The hanger pin 9B is assembled to the sheet holder 9A at one end in the longitudinal direction (the upper end side in FIG. 8A), and the other end in the longitudinal direction (the lower end side in FIG. 8A) is the sheet holder 9A. Is not assembled. For this reason, the hook portion 9 is configured in a rectangular ring shape that is cut and opened at the other end in the longitudinal direction (the lower end side in FIG. 8A), that is, in a substantially U-shape that is opened at the lower end side. ing.

  Further, as shown in FIG. 8B, the sheet holder 9A includes a first holder plate 9C disposed on one end side in the thickness direction with the sheet 3 interposed therebetween, and a second holder plate disposed on the other end side in the thickness direction. The sheet holder 9A is assembled to the front end side of the sheet 3 by sandwiching the sheet 3 from the thickness direction with these holder plates 9C and 9D.

  As shown in FIG. 9, the first and second holder plates 9C and 9D are connected by a thin portion 9E that is thinner than other portions, and the sheet holder 9A is connected by this thin portion 9E. After being bent, the holder plates 9C and 9D are fixed by screws 9F (see FIG. 2) so that they are in close contact with each other. Thereby, the state where the sheet 3 is sandwiched (clamped) by the sheet holder 9A is maintained.

  The hanger pin 9B is made of a material having excellent elasticity such as spring steel, and the hanger pin 9B is attached to the sheet holder 9A on one end side in the longitudinal direction (the upper end side in FIG. 9A). A hanger part 9G for assembling is provided, and a curved part 9H that is curved so as to protrude toward the sheet holder 9A is provided on the other end side in the longitudinal direction. Incidentally, a portion 9K that is curved so as to protrude to the opposite side of the curved portion 9H is a curve for facilitating attachment of a color navigation or a string.

  At least one of the first and second holder plates 9C and 9D is provided with a groove portion (not shown) that fits in a state where the hanger portion 9G is positioned, and the hanger portion 9G is provided in the groove portion. In the fitted state, it is sandwiched between the first and second holder plates 9C and 9D and fixed to the sheet holder 9A.

  Further, as shown in FIG. 2, a permanent magnet 9J is disposed on the same side (second holder plate 9D) as the plate portion (7C) of the sheet holder 9A. Is fixed to the sheet holder 9A by a mechanical fastening means such as a screw in a state of being fitted in a recess provided in the. For this reason, the permanent magnet 9J does not protrude from the sheet holder 9A, and the both 9A and 9J are substantially flush.

The sheet holder 9A is provided with a through hole 9L, and the hook portion 9 can be attached to the attachment target body by passing a string or a wire through the through hole 9L.
1.4 Structure of Holding Casing 1.4.1 Outline of Holding Casing As shown in FIG. 2, the holding casing 7 is formed in a substantially U shape by a first support portion 7A, a second support portion 7B, and a plate portion 7C. As shown in FIG. 4, the first support portion 7A is provided on one end side in the axial direction (the upper end side in FIG. 4) and rotatably supports the drum shaft 5C, and the second support portion 7B. Is provided on the other axial end side (the lower end side in FIG. 4) and rotatably supports the drum shaft 5C.

  As shown in FIG. 2, the plate portion 7C is a frame material that extends in the axial direction so as to connect the first support portion 7A and the second support portion 7B, and holds both the support portions 7A and 7B. The plate portion 7C according to the embodiment is made of a ferromagnetic material such as SPHC. Since the first support part 7A and the second support part 7B are made of a resin material such as ABS, the plate part 7C and the support parts 7A and 7B are connected by a fastening means such as a screw. .

  Further, the plate portion 7C is provided with a permanent magnet 7D as attachment means for attaching the seat reel 1 (holding casing 7) to an attachment object such as a wall or a column. The permanent magnet 7D is provided with the plate portion 7C. It is fixed to the plate portion 7C by fastening means such as a screw in a state of being fitted in a recess provided in the plate. For this reason, permanent magnet 7D does not protrude from plate part 7C, and both 7C and 7D are substantially flush.

The plate portion 7C is provided with a through hole 7E, and the seat reel 1 can be attached to the attachment target body by passing a string, a wire or the like through the through hole 7E.
Further, in the second support portion 7B, as shown in FIG. 4, a take-up spring (in this embodiment, a spring spring) that applies an elastic force in a direction to take up the sheet 3 to the drum 5 (drum shaft 5C). 11 is stored.

  The winding spring 11 is locked at the center side of the spiral by the drum shaft 5C and locked at the outer side by the second support portion 7B. Therefore, when the sheet 3 is extended and the drum 5 is rotated, the winding spring 11 is wound so that the winding spring 11 is tightened. Therefore, the winding spring 11 rotates the drum 5 in the winding direction as its restoring force. Try to.

  On the other hand, a rotation suppression mechanism 13 that suppresses the rotation of the drum 5 is provided in the first support portion 7A. The rotation suppression mechanism 13 is configured so that the drum 5 is wound by the elastic force of the winding spring 11. When the angular velocity exceeds a preset angular velocity, the drum 5 is prevented from rotating.

  Further, the first support portion 7A has a seat lock mechanism 15 (see FIG. 5) that prevents the drum 5 from rotating and fixes the position of the assembly hole 5D to a preset position with respect to the holding casing 7 (first support portion 7A). 10).

  Further, as shown in FIG. 3, the first support portion 7 </ b> A is provided with a locked hole 7 </ b> G capable of locking the hook portion 9 by inserting the hanger pin 9 </ b> B. By inserting (hanger pins 9B) into the locked holes 7G of the other sheet reels 1 and locking them, the plurality of sheet reels 1 (sheets 3) can be connected in a daisy chain.

  And the sheet | seat entrance / exit 7H in which the sheet | seat 3 comes in / out with rotation of the drum 5 is set to the plate part 7C side among the holding casings 7, and this sheet entrance / exit 7H is orthogonal to the drum shaft 5C, and It opens toward the direction parallel to the plate portion 7C (right side in FIG. 3) and is set on the plate portion 7C side from the axis of the drum 5 (drum shaft 5C).

  Specifically, the sheet entrance / exit 7H is configured by a rectangular opening surrounded by the guide roller 7J, the plate portion 7C, and the first and second support portions 7A and 7B. The guide roller 7J extends from the first support portion 7A side to the second support portion 7B side, and rotates while contacting the surface of the sheet 3 when the sheet 3 enters and exits, thereby guiding the movement of the sheet 3. To do.

1.4.2 Structure and Operation of Rotation Suppression Mechanism As shown in FIG. 5, the rotation suppression mechanism 13 is composed of a locking member 13A, a return spring 13B, a locking projection 13C, and the like. A locking claw for locking that is swingably assembled to the flange portion 5B of the drum 5 through a shaft member such as a P screw 13D.

  And the rocking | swiveling center (position of P screw 13D) of 13 A of locking members is set to the position which shifted | deviated from the drum shaft 5C to the outer diameter side. For this reason, the locking member 13A rotates integrally with the drum 5 around the axis L1 (drum shaft 5C) and swings and displaces in a direction approaching or separating from the axis L1 (drum shaft 5C). it can.

  The return spring 13B is a return spring that displaces the locking member 13A in a direction that brings the locking member 13A close to the axis (the state shown in FIG. 5A), and the return spring 13B according to the present embodiment has a P on the coil portion. A torsion coil spring into which the screw 13D is inserted is employed.

  When the locking member 13A is displaced in a direction away from the axis L1 (the state shown in FIG. 5B), the locking protrusion 13C is engaged so that the locking member 13A is hooked. 13 </ b> A is locked, and the locking protrusion 13 </ b> C is provided on the first support portion 7 </ b> A constituting a part of the holding casing 7.

  That is, as shown in FIG. 5A, the locking protrusion 13C is a protrusion protruding toward the drum shaft 5C from a position shifted to the outer diameter side from the drum shaft 5C, and the axis L1 (drum shaft 5C ) Is provided around.

  Of the slopes 13F and 13G extending from the vertex 13E to the outer diameter side of the locking projection 13C, the slope 13F positioned on the extension direction side with respect to the vertex 13E is parallel to the radial direction (radial direction) or on the outer diameter side. It is inclined so as to be positioned closer to the winding direction than the radial direction as it goes to. On the other hand, the slope 13G positioned on the winding direction side with respect to the apex 13E is inclined toward the winding direction side from the radial direction toward the outer diameter side.

  For this reason, when the angular velocity of the drum 5 is equal to or lower than the preset angular velocity, the locking member 13A is in the retracted state shown in FIG. 5A by the elastic force Fs of the return spring 13B, so that the drum 5 is free. Can be rotated.

  When the angular velocity of the drum 5 exceeds a preset angular velocity, the centrifugal force Fc acting on the locking member 13A increases, and the locking member 13A is displaced in a direction away from the axis L1 side, and the locking member 13A. And the locking projection 13C are displaced to the locked state.

  At this time, when the drum 5 is rotating in the winding direction, the inclined surface 13F of the locking projection 13C is inclined so as to be positioned on the winding direction side from the radial direction toward the outer diameter side. Therefore, after the locking member 13A and the locking projection 13C collide, both 13A and 13C are engaged. Therefore, after the rotation of the drum 5 is decelerated (suppressed), the rotation of the drum 5 is stopped when the locking member 13A is engaged with the locking protrusion 13C.

  On the other hand, when the angular velocity of the drum 5 exceeds a preset angular velocity and the drum 5 rotates in the extending direction, the more inclined surface 13G is directed toward the outer diameter side, the more the winding direction is closer to the winding direction. Since it is inclined, after the locking member 13A and the locking projection 13C (slope 13G) collide, the locking member 13A gets over the apex 13E and reaches the adjacent locking projection 13C (slope 13G). Therefore, the drum 5 rotates in the extending direction as the sheet 3 extends without stopping.

1.4.3 Seat Lock Mechanism As shown in FIG. 10, the seat lock mechanism 15 is configured by inserting the lock rod 5G provided on the first support portion 7A into the cylinder portion 5F provided on the flange portion 5B. The rotation of the drum 5 is restricted, and the lock rod 5G is assembled to the first support portion 7A so that it can be displaced in the axial direction of the cylindrical portion 5F.

  That is, the cylindrical portion 5F is provided at a position shifted from the axis L1 to the outer diameter side of the flange portion 5B so that the axial direction thereof is parallel to the direction of the axis L1, and the lock rod 5G has a male screw on the outer peripheral portion. It is formed and inserted into the female screw hole formed in the first support portion 7A.

  For this reason, by turning the knob 5H provided on the distal end side of the lock rod 5G, the lock position (see FIG. 10B) in which the lock rod 5G is inserted into the cylinder portion 5F and the lock rod 5G are It can be displaced between the unlocked position (see FIG. 10A) separated from the portion 5F, and the lock bar 5G can be held at the locked position or the unlocked position.

  As shown in FIG. 3, the cylindrical portion 5F is provided in the first support portion 7A when the center of the cylindrical portion 5F coincides with the center of the lock rod 5G when viewed from the direction parallel to the axis L1. The set sheet insertion slit hole 7F and the assembly hole 5D are set to coincide with each other. Therefore, by setting the lock rod 5G to the lock position, the drum 5 can be stopped in a state where the sheet insertion slit hole 7F is aligned with the assembly hole 5D.

2. Specific example of how to use the sheet reel 2.1 The territory Since the drum 5 is always elastically acted by the winding spring 11, the sheet 3 is stored in the sheet reel 1 while being wound around the drum 5, And the hook part 9 (sheet | seat holder 9A) is accommodated in the state fitted in the recessed part 7K provided in the 1st, 2nd support part 7A, 7B, as shown in FIG.

  And when territory, after extending the sheet 3 by pulling the hook portion 9 away from the holding casing 7 in a state where the plate portion 7C of the holding casing 7 is fixed to an attachment object such as a wall or a column, The hook portion 9 is fixed to the attachment target body.

  At this time, the fixing method of the holding casing 7 is (1) a method of fixing to the mounting object with the permanent magnet 7D embedded in the plate portion 7C, or (2) binding to the through hole 7E provided in the plate portion 7C. There is a method of fixing to an attachment object through a band or a wire.

  In addition, the hook portion 9 can be fixed by (1) a method of fixing to the attachment object with a permanent magnet 9J embedded in the sheet holder 9A, and (2) a binding band or the like in a through hole 9L provided in the sheet holder 9A. (3) A method of inserting the hanger pin 9B into the locked hole 7G provided in the other seat reel 1 and connecting it to the other seat reel 1 (FIG. 11), Or (4) By passing the sheet 3 between the hanger pin 9B and the sheet holder 9A, as shown in FIG. 12, the front end side of the sheet 3 is looped (annular) and wrapped around a pillar or a load cone (pylon). There are ways to do this.

2.2 Sheet Replacement As shown in FIG. 3, the sheet inlet / outlet port 7H is set on the plate portion 7C side from the drum 5 axis (drum shaft 5C) when viewed from the opening direction. When the sheet 3 is extended in the opening direction (toward the right side in FIG. 3) until the sheet stops, the sheet insertion slit hole 7F and the assembly hole 5D are brought into a coincident state. In this state, the lock rod 5G is set to the lock position.

Thereafter, the sheet 3 can be detached from the drum 5 by moving the sheet 3 in the direction of the axis L1 so as to remove the sheet 3 from the drum 5 (see FIG. 7A).
When the sheet 3 is assembled to the drum 5, the sheet 3 is inserted into the assembly hole 5 </ b> D and then the lock rod 5 </ b> G is set to the unlocking position, as opposed to removing the sheet 3 from the drum 5. Since the drum 5 is rotated in the winding direction by the elastic force of the spring 11, the sheet 3 is automatically wound around the drum 5.

  At this time, if the angular velocity of the drum 5 exceeds a preset angular velocity, the engaging member 13A and the engaging protrusion 13C are engaged to stop the rotation of the drum 5, so that the angular velocity of the drum 5 is preset. It is desirable to apply a force in the extending direction to the seat 3 or the hook portion 9 so that the angular velocity is less than the predetermined angular velocity.

2.3 Assembly of the hook portion For example, when damage occurs on the front end side of the sheet 3, the damaged portion is cut and removed, and the hook portion 9 is assembled to the front end of the sheet 3 after cutting and removal. The reel 1 can be recycled.

  At this time, in the present embodiment, the sheet holder 9A includes first and second holder plates 9C and 9D that sandwich the sheet 3 in the thickness direction, and screws 9F for fixing both the holder plates 9C and 9D. Therefore, if the screw 9F is loosened and the existing hook portion 9 is removed from the sheet 3, and the screw 9F is tightened with the removed sheet 3 being sandwiched by the removed hook portion 9, the hook portion can be easily 9 can be attached to the seat 3.

3. Features of the Seat Reel According to the Present Embodiment In the present embodiment, as shown in FIG. 11, a plurality of seat reels are obtained by engaging the hook portion 9 (hanger pin 9B) with the holding casing 7 of the other seat reel 1. Therefore, a large range can be partitioned without making the sheet excessively long. Therefore, it is possible to partition a large range while suppressing the deterioration of the winding property of the sheet 3 and the enlargement of the sheet reel 1.

  Further, since the hook portion 9 is formed in an annular shape in which a part thereof is cut and opened, as shown in FIG. 12, by passing the sheet 3 through the hook portion 9, the front end side of the sheet 3 can be easily formed. It can be annular (annular).

  Therefore, in this embodiment, after the front end side of the sheet 3 is wound around an existing column or the like, the front end side of the sheet can be easily formed by passing the sheet 3 through the hook portion 9 configured in an annular shape and making the front end side annular. While being able to tie to the existing support | pillar etc., the tying can also be cancelled | released easily.

  By the way, since the winding spring 11 causes the elastic force (winding force) in the direction of winding the sheet 3 to act on the drum 5, the winding force becomes larger as the sheet 3 is extended longer, and the usability becomes inconvenient. However, in this embodiment, since the rotation suppression mechanism 13 is provided, it is possible to suppress an excessive increase in the winding force, and it is possible to improve usability.

  By the way, when the sheet 3 is wound around the drum 5, normally, the sheet 3 is in a zigzag state in the direction of the axis L1, as shown in FIG. The end portion (vertical direction) is pulled to the drum 5 side by the tension generated in the sheet 3 with the winding force, and the sheet 3 is bent and deformed so that the surface on the drum 5 side is recessed.

And if the sheet | seat 3 bends so that the surface side may be dented, there exists a possibility that visibility, such as a posting pattern described on the surface, may fall remarkably.
On the other hand, in the present embodiment, the sheet 3 is wound around the drum 5 so that the surface on which the posting pattern or the like is described faces the outer peripheral side from the back surface on which the posting pattern or the like is not described. The sheet 3 is easily bent and deformed so that the back surface on which the posting pattern or the like is not described is recessed. Therefore, in this embodiment, since it can suppress that the sheet | seat 3 will bend and deform | transform so that the surface side may be dented, it can prevent that the visibility of the posting pattern etc. which were described on the surface falls remarkably.

  Further, in the present embodiment, the sheet inlet / outlet port 7H is set on the plate portion 7C side when viewed from the opening direction (right side in FIG. 3), so that when the sheet 3 is extended, the hook portion 9 and the plate It is possible to suppress the stretched sheet 3 from being largely inclined with respect to a virtual tangent line connecting the portion 7C.

  That is, since the plate portion 7C of the seat reel 1 (holding casing 7) is fixed to an attachment object such as a wall or a pylon, when the seat 3 is extended, the back surface of the sheet 3 is placed on the plate portion 7C side (attachment). It is desirable that the surface of the sheet 3 faces the side opposite to the plate portion 7C (hereinafter referred to as the front side). For this reason, it is necessary to set the sheet entrance 7H on the right side of FIG.

  However, if the sheet inlet / outlet port 7H is set on the opposite side of the plate portion 7C with respect to the axis L1 when viewed from the opening direction (right side in FIG. 3), the hook portion 9 is locked in the other seat reel 1 to be locked. When the plurality of sheet reels 1 are connected to each other by being locked to 7G, when the plurality of connected sheets 3 are viewed from the direction of the axis L1 (vertical direction), these sheets 3 become saw-toothed, It is not preferable.

  On the other hand, when the sheet entrance / exit 7H is set on the plate portion 7C side when viewed from the opening direction (the right side in FIG. 3), the sheet entrance / exit 7H extends with respect to a virtual tangent line connecting the hook portion 9 and the plate portion 7C. The sheet 3 can be prevented from being greatly inclined, and when the plurality of connected sheets 3 are viewed from the direction of the axis L1 (up and down direction), these sheets 3 are substantially linear, which is a preferable state.

  Further, in the present embodiment, a guide roller 7J that guides the movement of the sheet 3 while rotating is provided at a portion of the sheet entrance / exit 7H that contacts the surface of the sheet 3, so that it is described on the surface of the sheet 3. It is possible to suppress the display pattern or the like from disappearing due to rubbing.
