AI Technical Summary
Conventional anti-fall devices fail to prevent panel bodies from falling off at their free ends, especially when there is no adjacent panel body, such as those positioned next to a wall or in a free end state, due to inadequate design.
A fall prevention structure comprising a projection piece and a fall prevention piece that restricts the upward movement of panel bodies attached to support posts, including a bent piece inserted between the ceiling rail and panel body to prevent upward movement, and a projection piece fixed to the support post to secure the panel body, ensuring it does not fall off.
The structure effectively prevents panel bodies from falling off during earthquakes by restricting upward movement, especially at free ends, and can be applied to both sides of a support post, enhancing design aesthetics by covering exposed parts with a corner post.

Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of a falling-off prevention structure for a panel body such as a partition panel. [Background technology]
[0002] Currently, there are panel bodies used for partition panels, etc., that are attached to supports that are erected between the ceiling and floor. In this case, a configuration has been proposed in which mounting hardware is engaged with multiple locking holes provided in the support in the vertical direction, and the panel body is lowered with the mounting hardware engaged with the slits provided in the panel body, thereby locking the panel body in a non-detachable manner, thereby making it easy to attach and support the panel body to the support (see, for example, Patent Document 1). In this case, the slits are simply fitted and locked onto the mounting brackets from above, so if the panel body is inadvertently lifted due to vibrations from an earthquake or the like, it is anticipated that the slits will no longer be locked onto the mounting brackets and the panel body will fall off the support. Therefore, in the conventional case, a fall prevention device fixed with screws to a ceiling rail installed on the ceiling surface is used to restrict the lifting of the panel body, thereby preventing the panel body from falling off.

[0003] [Patent Document 1] Patent No. 6892304 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the conventional anti-fall devices are designed to prevent falling off by restricting the upward movement of panel bodies that are attached adjacent to the left and right of the support posts, but they do not prevent falling off of the free end edge of panel bodies that are attached without an adjacent panel body, such as panel bodies that end up next to a wall or in a free end (tip) state.Therefore, there are problems such as the inability to impart an effective anti-fall function to such panel bodies, and these are the issues that the present invention aims to solve. [Means for solving the problem]
[0005] The present invention was created in view of the above-mentioned circumstances and with the aim of solving these problems. The invention of claim 1 relates to a panel body that is attached to a support pole with its upper edge facing the visible surface of a ceiling rail attached to the ceiling surface by engaging a slit on the back surface of the panel body with a mounting bracket that is engaged with a plurality of engaging holes drilled in the vertical direction on the visible surface of the support pole, and that is provided with a fall prevention device for preventing the panel body from falling off the support pole when the panel body moves upward and the slit comes out of the mounting bracket, and that device comprises: This is a fall prevention structure for a panel body, which prevents the panel body attached to a support post that serves as the free end from falling off, and is composed of a projection piece that abuts the projection surface that serves as the free end of the upper end of the support post, a projection piece that is bent from the projection direction edge of the projection piece and inserted between the projection surface of the ceiling rail and the back surface of the panel body, and a fall prevention piece that is bent from the upper edge of the projection piece so as to abut the upper edge of the panel body, and is configured so that the fall prevention piece restricts the upward movement of the panel body by fastening the projection piece to the support post, thereby preventing the panel body from falling off. The invention of claim 2 is a fall prevention structure for a panel body described in claim 1, characterized in that the panel bodies are a pair attached to both front and rear visible surfaces of the support, the fall prevention device comprises a pair of front and rear visible piece portions bent from both end edges in the visible direction of the visible piece portion, and a pair of front and rear fall prevention piece portions bent from each of the visible piece portions, and the pair of front and rear fall prevention piece portions are configured to prevent the pair of panel bodies attached to both visible surfaces of the support from falling off. The invention of claim 3 is a fall prevention structure for a panel body described in claim 1 or 2, characterized in that the support is attached with a projecting piece portion exposed from the panel body of the fall prevention device, a projecting surface which becomes the free end of the support including the projecting piece portion, and a corner post which covers the projecting surface. [Effects of the Invention]
[0006] By adopting the invention of claim 1, the panel body that is attached to the support post at the free end in a freely detachable manner can be reliably prevented from falling off using a fall prevention device, thereby avoiding the problem of the panel body attached to the free end falling off in the event of an earthquake. By adopting the invention of claim 2, it is possible to prevent the panel body from falling off not only in cases where the panel body can be attached to one of the visible surfaces of the support, but also in cases where the panel body is attached to both the front and rear visible surfaces, with a single fall prevention device, making it highly convenient. By adopting the invention of claim 3, the projected surface and the visible surface that become the free end of the support, including the projected piece portion and the visible piece portion that are exposed from the panel body of the anti-fall-off device, are covered by the corner post, thereby improving the design of the free end portion.

[0008] An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a partition panel, 2 denotes a support post for attaching said panel 1, and said support post 2 has its lower end attached to a floor rail 3 provided on floor surface F. Support bracket 4 is fitted into the upper end of support post 2 so that it can be adjusted up and down. The upper end of support bracket 4 is fitted into leg piece 5b of U-shaped ceiling rail 5 provided on ceiling surface C, and tongue piece 4a provided on the upper edge of support bracket 4 is fastened to straddling piece 5a, which forms the visible surface of ceiling rail 5, with screws 4b. With this configuration, support post 2 including support bracket 4 functions as a frame-side member attached to the frame together with floor rail 3 and ceiling rail 4. On both the left and right sides of the visible surface (front and back surfaces) 2a of the support 2, locking holes (slits) 2b are drilled at appropriate intervals in the vertical direction, and one piece 6a of a roughly H-shaped mounting bracket 6 is fitted into the support 2, while the other piece 6b protrudes from the front and back surfaces of the support 2, and the mounting bracket 6 is assembled to the support 2 in such a manner that the lower edge of the neck-shaped body 6c is locked onto the lower edge of the locking hole 2b.
[0009] Meanwhile, slits (locking holes) 1a corresponding to the locking holes 2b are provided on the rear surface of the panel at both left and right ends of the panel body 1. Then, by lifting the panel body 1 slightly above the mounting position and fitting it into the other piece 6b of the mounting bracket 6, and then lowering it, the other piece 6b fits into the panel body 1, and the upper edge of the body part 6c becomes locked into the upper end of the slit 1a, and the panel body 1 is attached to the support 2 with its upper and lower ends overlapping the ceiling rail 5 and the floor rail 3.
[0010] 7 and 8 are first and second fall prevention devices for preventing the attached panel body 1 from falling off, and the first fall prevention device 7 regulates the upward movement of the adjacent side edge of one of the panel bodies 1 when the panel bodies 1 are adjacent on the left and right, thereby preventing the one panel body 1 from falling off, and the second fall prevention device (corresponding to the ``fall prevention device'' of this invention) 8 regulates the upward movement of the free end side edge of the panel body 1, which is the free end, thereby preventing the panel body 1 from falling off.
[0011] The first fall prevention device 7 is composed of a vertical plate-shaped sight piece 7a that is long in the left-right direction, a fall prevention piece 7b that is bent into a horizontal plate shape (inverted L-shape) from the upper edge of one half of the left-right half (tip) of the sight piece 7a, and a hanging piece 7c that hangs down and extends downward from the other left-right end (base end) of the sight piece 7a, and in a structure in which left and right panel bodies 1 are attached adjacent to a support 2, the first fall prevention device 7 is attached to one panel body 1 that has been attached to the support 2 first, at a stage before the other panel body 1 is attached to the support 2, thereby preventing the one panel body 1 from falling off.
[0012] In this case, the first anti-fall-off device 7 first has its sight piece portion 7a facing the sight surface 2a of the support 2, and the tip portion where the anti-fall-off piece portion 7b is formed is inserted between the leg piece portion 5b of the ceiling rail 5 and the back surface of the panel body 1, and then the anti-fall-off piece portion 7b comes into contact with the upper edge portion 1b of the adjacent side edge portion of the panel body 1 that was previously installed, and then the hanging piece portion 7c is bent to form a bent piece portion 7d, and the edge of this bent piece portion 7d is set in a state where it is in contact with the edge of the sight surface 4c of the support bracket 4 (or the bent surface 4d if the bent surface 4d is on that side). Next, the portion of the visible piece 7a that is exposed from the panel body 1 is fixed to the ceiling rail 5 via a screw 7e, and the first anti-fall-off device 7 is fixed to the ceiling rail 5, which is a member on the main body side.By configuring it in this way, when the panel body 1 that has been attached to the support 2 in advance attempts to move upward due to vertical shaking caused by an earthquake, the upward movement of the adjacent side edge of the panel body 1 is restricted by the anti-fall-off piece 7b, thereby preventing the panel body 1 that has been attached in advance from falling off.
[0013] In this way, after the first anti-fall-off device 7 is attached to the ceiling rail 5 to prevent the previously installed panel body 1 from falling off, an adjacent panel body 1 is subsequently attached to the same support pillar sight surface 2a, so that the adjacent panel bodies 1 are attached in a continuous left-right direction via the support pillar 2, and most of the exposed part of the sight piece 7a from the previously installed panel body 1, including the screws 7e used to attach and fix the first anti-fall-off device 7, is covered by the subsequently installed panel body 1, so that only the gap between adjacent panels 1 can be seen.
[0014] In contrast, the second anti-fall-off device 8 restricts the upward movement of the free end edge of the panel body 1 which is attached to the support 2, which serves as the free end when there is no body side component such as a wall W, thereby preventing the panel body 1 from falling off.It is configured with a projecting piece 8a which abuts the upper edge of the projecting surface 2d of the support 2, a visible piece 8b which is bent from both end edges in the projecting direction (front-to-back direction) of the projecting piece 8a to form the leg piece of the second anti-fall-off device 8, and a fall-off prevention piece 8c which is bent from the upper edge of the visible piece 8b outward in the front-to-back direction and abuts against the upper edge 1b of the panel body 1, thereby restricting the upward movement of the panel body 1 in the direction in which the slit 1a comes out of the mounting bracket 6, thereby preventing the panel body 1 from falling off the support 2.
[0015] In this case, the second captive device 8 has a visible piece 8b formed in an inverted L shape by a vertical piece 8d and an upper piece 8e, and a captive piece 8c bent and formed at the upper edge of the front half of the upper piece 8e, and is attached to the support 2 which serves as the free end of the panel body 1. In this case, the upper edge of the front half of the upper piece 8e is inserted between the panel body 1 and the leg piece 5b of the ceiling rail 5, and the captive piece 8c is set so that it abuts the upper edge 1b of the edge of the free end of the panel body 1. In this set state, the visible piece 8a is attached and fixed to the visible surface 2d which serves as the free end of the support 2 with a screw 10, allowing the second captive device 8 to be attached to the support 2.
[0016] The support 2, which becomes the free end in this way, has the half of the front, visible surface 2a, on the side where the panel body 1 is assembled, covered by the panel body 1, but the free end half of the visible surface 2a and the visible surface 2d are exposed, along with the visible piece 8a of the second anti-fall-off device 8 and the visible piece 8b of the part not covered by the panel body 1.Therefore, in this embodiment, a corner post 11 which is U-shaped in plan view and whose upper edge reaches the ceiling surface C is attached to cover the exposed part, and the tip (free end) of the ceiling rail 5 is also covered with a cover material 5c, thereby improving the design.
[0017] In addition, in this embodiment, a third anti-fall device 12 is used to regulate the upward movement of the free end edge of the panel body 1 attached to the support 2 at the part close to the wall W (wall edge part), thereby preventing the panel body 1 from falling off. This third anti-fall-off device 12 is L-shaped and includes an anti-fall-off piece portion 12a that abuts against the upper edge portion 1b of the free end edge portion of the panel body 1 when the panel body 1 is attached to the support 2, and a fixed piece portion 12b that is bent upward from the anti-fall-off piece portion 12a and fixed to the leg piece portion 5b of the ceiling rail 5 via a screw 12c. In this case, the third fall prevention device 12 prevents the panel body 1 attached to the support 2 from falling off due to upward movement, and the part of the support 2 on the wall W side is fitted into a wall rail 13 which is U-shaped in plan view and is configured to close the gap between the panel body 1 and the wall W.
[0018] In the present embodiment configured as described above, when the panel body 1 is attached to the support 2, which is the free end and has no wall W, the second fall-off prevention device 8 is used to prevent the panel body 1 from falling off the support 2 when the panel body 1 moves upward and the slit 1a comes out of the mounting bracket 6. The second fall-off prevention device 8 has a projection piece 8a that abuts the upper edge of the projection surface 2d of the support 2, which is the free end, and a projection piece 8b that is clamped between the leg piece 5b of the ceiling rail 5 and the back surface of the panel body 1, and the projection piece 8b The anti-fall piece 8c bent from the upper edge is assembled so as to abut against the upper edge 1b of the panel body 1, and if the support 2 is an independent free end without a wall W or the like, by fastening the projected piece 8a to the projected surface 2d of the support 2 with a screw 10, when the panel body 1, which is a free end, tries to move upward due to earthquake vibrations, the upward movement is restricted by the anti-fall piece 8c, and as a result, the panel body 1, which is attached to the support 2 in a free end state, can be prevented from falling off using the second anti-fall device 8.
[0019] In this embodiment, the second anti-fall-off device 8 for preventing such a free end of the panel body 1 from falling off the support 2 is configured to accommodate a pair of front and rear panel bodies 1 attached to both front and rear facing surfaces 2a of the support 2, and is therefore equipped with a pair of front and rear facing pieces 8b bent from both front and rear end edges of the facing piece 8a, and a pair of front and rear anti-fall-off pieces 8c bent from the upper end edges of each of the facing pieces 8b.As a result, a single second anti-fall-off device 8 can be used to prevent the pair of panel bodies 1 attached to both front and rear facing surfaces 2a of the support 2 from falling off, thereby reducing the number of parts.
[0020] Furthermore, in this device, the projected surface 2d, which is the free end of the support 2, including the projected piece portion 8a and the visible piece portion 8b exposed from the panel body 1 of the second anti-fall-off device 8, and the visible surface 2a, which is the free end of the support 2, are covered with a corner post 11, so that the appearance of the part becomes that of the corner post 11, improving the design. [Industrial Applicability]
[0021] The present invention can be used as a structure for preventing a panel body such as a partition panel from falling off. [Explanation of symbols]
