Description

  The present invention relates to a bag retainer.

  Conventionally, when a cylindrical cage is attached to a building, a pair of members curved in a circular arc shape and a movable arm are connected to each other by one hinged end so as to be freely rotatable. A holding tool is used in which the opposite end is freely detachable (see, for example, Patent Document 1).

  At the time of mounting, the support and the movable arm are annularly surrounded by the arc-shaped support surface of the support fixed to the wall surface of the building by the integrally provided legs and the movable arm, and are pressed against the outer peripheral surface of the rod. Is locked at the opposite end opposite to the hinge portion.

  However, in the conventional holder, the hinge part at one end of the support and the locking means of the movable arm locked by the locking part at the other end are located on both side ends in front view. For this reason, when viewed from the front, they protrude from the side and are visually recognized, so that there is a problem that the appearance in the mounted state is not clean.

  In patent document 2, the technique which improves the external appearance in an attachment state is proposed. In this technique, the hinge part and the locking part of the support body are provided so as to be closer to the support body side than the central axis in the locked state. Thereby, the hinge part at one end of the support and the locking means of the movable arm locked to the locking part at the other end are made difficult to visually recognize in front view, thereby improving the appearance. .

  A flat plate portion 24 is provided at the tip of one arcuate support surface 21b of the support 2 so as to face the front in an attached state and extend outward. The locking portion 6 is constituted by a locking hole 25 formed in the flat plate portion 24. The outer end of the flat plate portion 24 is bent vertically rearward toward the wall surface of the building to form a bent portion 24a.

  And the part by the side of the latching | locking part 6 of the support body 2 in the attachment state in the movable arm 3 is provided with the 1st piece part 32 and the 2nd piece part 34. As shown in FIG. The first piece 32 extends linearly away from the flange 40 toward the tip. The first piece 32 has a central axis A in FIG. 5, that is, a position where it becomes the center of the arc shape of the movable arm 3 and becomes the central axis of the eaves 40, and then moves backward toward the wall surface of the building. It extends straight. A range indicated by a left arrow in FIG. 5 constitutes a rectangular plate-shaped first piece portion 32.

  The first piece portion 32 is formed with a bullet piece 35 projecting inward from the inner surface thereof. The bullet piece 35 is formed integrally with the first piece portion 32 and has a tongue-like shape with one base end as a fulcrum, and extends from the base end side of the first piece portion 32 to the tip side. It protrudes inward from the inner surface of the piece 32.

  The elastic piece 35 can be elastically deformed. When the hook 40 is inserted and supported by locking the movable arm 3 to the support body 2, the elastic piece 35 is formed on the outer peripheral surface of the hook 40. Are supported by elastic pressure. Further, when the hook 40 is inserted and supported by the elastic force of the bullet piece 35, an outward pressing force is applied to the first piece portion 32, and the outward pressing force causes the distal end of the support body 2 to move. The locking claw 5 can be locked to the outer side 25a of the locking hole 25 provided.

  The second piece 34 is bent so as to form an obtuse angle from the first piece 32 toward the flange 40 and extends linearly. That is, it is bent inward from the bent portion 33 to form a rectangular plate-like second piece portion 34.

  At the tip of the second piece portion 34, there is a locking claw 5 that faces outward from the bent side of the second piece portion 34 via a constricted portion 36. The movable arm 3 is locked by a locking claw 5 coming into contact with an outer side 25 a of a locking hole 25 provided in the support 2.

  In the movable arm 3, it is preferable that the locking claw 5 is located on the inner side of the side end 32 a on the first piece portion 32 side in a front view. If it does in this way, in the front view in an attachment state, as shown in FIG. 5, the hook front-end | tip 5a of the latching claw 5 will be located in the center axis | shaft A side rather than the side end 32a in a latching state. Therefore, as shown in FIG. 2, it is possible to prevent the locking claws 5 from being seen at all, and the appearance is clean and good.

  Further, as shown in FIG. 5, a bent portion 24 a that is bent vertically is provided at the outer end of the flat plate portion 24 provided with the locking hole 25 of the support 2. Therefore, in the locked state, the locking claw 5 can be hidden from the outside by the bent portion 24a so that the locking claw 5 cannot be seen at all. In addition, since the bent portion 24a is substantially collinear with the side end 32a on the first piece portion 32 side in a front view, the appearance is clearer and better.

  With the bag holder 1 configured as described above, the bag 40 is fixed along the wall surface of the building as follows.

  On the wall surface of the building where the bag 40 is to be installed, a plurality of bag holders 1 are installed in series for each predetermined portion in the length direction. Thereafter, the support body 2 and the movable arm 3 of each bag retainer 1 are supported so as to embrace a predetermined portion of the bag 40.

  At this time, the movable arm 3 that is rotatably attached to the support 2 in the horizontal direction releases the lock between the lock claw 5 at the tip and the lock hole 25 at the tip of the support 2. Then, it is released from the support 2 as shown in FIG.

  In this opened state, the outer peripheral surface of the collar 40 is fitted into the movable arm 3. The outer peripheral surface of the flange 40 is supported by being pressed against the movable arm 3 by the elastic force of the bullet piece 35. Thereby, a part of outer peripheral surface of the collar 40 is elastically supported.

  In this state, the opened movable arm 3 is rotated by the hinge portion 4, and the outer peripheral surface on the back side of the heel 40 not supported by the movable arm 3 is fitted into the support 2.

  Then, the locking claw 5 at the tip of the movable arm 3 is locked in the locking hole 25 provided at the tip of the support 2. As a result, the heel 40 is inserted into the annular space formed by the curved support surface 31 of the movable arm 3 and the arc-shaped support surfaces 21a and 21b of the support 2, and the support 2 and It is fixed so as to be held by the movable arm 3.

  At this time, the collar 40 is pressed by the bullet 35 along the inner surface of the first piece 32 of the movable arm 3. The elastic piece 35 is elastically bent outward and deformed, and the flange 40 is supported along the curved support surface 31 of the movable arm 3 and the arc-shaped support surfaces 21 a and 21 b of the support 2. The first piece 32 is locked to the outer side 25 a of the locking hole 25 provided at the tip of the support body 2 by the outward pressing force due to the elastic force of the bullet 35. The claw 5 can be locked.

  When the collar 40 is fitted into the movable arm 3 in the opened state of FIG. 3 and is pressed against the support 2, the locking claw 5 is attached to the outer edge of the locking hole 25 in the flat plate portion 24 of the support 2. It hits the 25a side. When further pushed in, the locking claws 5 enter the locking holes 25 and are locked by the elastic force of the first piece portion 32 and the second piece portion 34 while the outer side portion 25a contacts and slides.

  In this attached state, as shown in the front view of FIG. 2, the hinge part 4 at one end of the support 2 is hidden behind the movable arm 3 and cannot be seen. Since the locking portion 6 and the locking claw 5 at the other end are also on the inner side of the first piece portion 32 extending straight toward the wall surface of the building, they are hidden behind the outer edge portion 25a of the movable arm 3 and are not visible.

  That is, since the second piece 34 bent inward is formed, the second piece 34 is locked closer to the central axis A than the first piece 32 in a front view. Therefore, the locking portion 6 and the locking claw 5 are hidden behind the movable arm 3 and are not visible, and the appearance is clean. Further, the outer side of the flat plate portion 24 provided with the locking portion 6 is bent to form a bent portion 24a. The bent portion 24a covers the locking claw 5 of the movable arm 3 from the outside, and the width in the direction toward the wall surface of the building is matched with the first piece portion 32, so the appearance is clearer.

  In other words, as shown in FIG. 5, the first piece 32 that is further away from the flange 40 is formed toward the tip, so that a gap 50 is formed between the movable arm 3 and the flange 40. Thereby, at the front end side of the 1st piece part 32, the margin which can be bent inward so that the latching | locking part 6 and the latching claw 5 may become difficult to see is made. Therefore, the 2nd piece part 34 which accept | permits the elastic movement in the case of engagement / disengagement can be provided. Therefore, even if the locking claw 5 protruding outward is provided, the second piece 34 facing inward is inward of the side end 32a of the movable arm 3 in the front view, and is almost identical to the first piece 32. It can be accommodated in the bent portion 24a on the line.

  When removing the heel 40 from the heel holder 1, the first piece 32 is pushed inward to release the engagement by narrowing the gap 50, and the movable arm 3 is pulled back to open the movable arm 3. Can take out the basket 40.

  The bag retainer 1 of the present embodiment is provided with the first piece portion 32 and the second piece portion 34 on the movable arm 3 to form the gap 50 in FIG. It is made to lock in the locking hole 25 of the support body 2. Therefore, the outer diameter dimension of the flange 40 and the inner diameter dimension of the retainer 1 (the inner diameter dimension of the annular space formed by the curved support surface 31 of the movable arm 3 and the arc-shaped support surfaces 21a and 21b of the support body 2). Even if there is an error, the locking force is absorbed and stabilized by the first piece 32 and the second piece 34, and the influence of the locking claw 5 on the locking hole 25 is small. Therefore, even when the outer diameter of the flange 40 is slightly smaller than the design dimension, or when the inner diameter of the retainer 1 is slightly larger than the design dimension, the support body 2 and the movable arm are also provided. It is possible to suppress the occurrence of rattling in the heel 40 supported by 3 and to support stably. On the other hand, even if the outer diameter of the flange 40 is larger than the design dimension, or the inner diameter of the retainer 1 is smaller than the design dimension, it is difficult to lock the support 2 and the movable arm 3. It is suppressed. Thus, the bag holder 1 of this embodiment is excellent in tolerance of dimensional accuracy, and can ensure the accuracy of fitting with the bag 40.

  According to the bag retainer 1 of the present embodiment described above, the first piece 32 and the second piece 34 are formed, so that the gap in FIG. 50, the locking claw 5 of the movable arm 3 can be locked in the locking hole 25 of the support 2. Therefore, the hinge part 4 at one end of the support 2 and the locking part 6 at the other end and the locking claw 5 of the locked movable arm 3 are not visible from the front in the mounted state. Can be fixed to. Therefore, the appearance is clean and good. Furthermore, since the locking force is absorbed and stabilized by the gap 50 formed between the first piece portion 32 and the second piece portion 34, the tolerance of dimensional accuracy is excellent. The accuracy of the fitting with the flange 40 can be ensured.

  Furthermore, the locking claw 5 of the movable arm 3 is located on the inner side of the side end 32a on the first piece portion 32 side in a front view. Thereby, the latching claw 5 becomes difficult to visually recognize, and the appearance is improved more clearly.

  Further, the first piece portion 32 is formed with a bullet piece 35 protruding inward from the inner side surface thereof. As a result, when the collar 40 is inserted and supported by locking the movable arm 3 to the support body 2, the outer peripheral surface of the collar 40 can be supported by pressing with an elastic force. Further, when the hook 40 is inserted and supported by the elastic force of the bullet piece 35, an outward pressing force is applied to the first piece portion 32, and the outward pressing force causes the distal end of the support body 2 to move. The locking claw 5 can be locked to the outer side 25a of the locking hole 25 provided.

  The mounting plate portion 26b is provided at the distal end of a long rectangular plate portion 26a that extends from the base end on the support 2 side toward the wall surface of the building in the mounted state.

  The mounting plate portion 26 b extends vertically from the rectangular plate portion 26 a and is formed in a direction along the longitudinal direction of the flange 40. The front end of the mounting plate portion 26b projects from the end in the width direction of the movable arm 3 when viewed from the front, and a mounting hole 26c such as a screw or screw is provided at the center of the flat plate.

  With the bag holder 1 configured as described above, the bag 40 is fixed along the wall surface of the building as follows. Similar to the above-described embodiment, the support 2 and the movable arm 3 of each scissors holder 1 are supported so as to embrace a predetermined portion of the scissors 40.

  A plurality of scissors holders 1 are installed in series for each predetermined portion in the longitudinal direction of the scissors 40. The mounting plate portion 26b provided at the tip of the leg portion 26 of the bag retainer 1 is fixed to the wall surface of the building through the mounting hole 26c with a screw, a screw or the like with its outer surface abutting against the wall surface of the building. As shown in FIG. 7, the leg portion 26 protrudes from the end in the width direction of the movable arm 3 in a front view. However, since it is formed in a direction along the longitudinal direction of the flange 40, only the movable arm 3 is visible in front view. Similarly to the above-described embodiment, the hinge part 4 at one end of the support 2, the locking part 6 at the other end, and the locking claw 5 of the locked movable arm 3 are also hidden from the front in the mounted state. Invisible.

Therefore, the hinge part 4 at one end of the support 2 and the locking claw 5 of the movable arm 3 locked with the locking part 6 at the other end are not visible from the front in the mounted state. It can be fixed on the wall and the appearance is clean. In addition, since the locking operation is absorbed by the gap 50 formed between the first piece portion 32 and the second piece portion 34 and the flange 40, the tolerance of dimensional accuracy is excellent. The accuracy of fitting can be ensured.

  Furthermore, according to the collar holder 1 of the present embodiment, the leg portion 26 protrudes from the end in the width direction of the movable arm 3 in front view, but is formed in a direction along the longitudinal direction of the collar 40. Therefore, only the movable arm 3 is visible in front view. And the hinge part 4 in the one end of the support body 2, the latching | locking part 6 in the other end, and the latching claw 5 of the latching movable arm 3 will also be in a state hidden and hidden from the front in the attachment state. Therefore, in the above-described embodiment, the same clean appearance as when the round bar-shaped leg portion 26 having a sharp tip is used is obtained. In addition, the leg portion 26 having the mounting plate portion 26b can be fixed to the wall surface of the building through the mounting hole 26c using screws or screws, so that the mounting to the wall surface of the building is not impaired.
