Description

Technical Field

[0001] The present invention relates to the technical field of a door body support structure of a panel body provided when installing a toilet booth or the like.

Background Art

[0002] Generally, for example, when installing a toilet booth, there is a structure in which a hinged door body is attached to a front panel body via upper and lower hinge fittings so as to be openable and closable. In such a case, an upper space (inter-column space) is often provided between the ceiling surface and the upper edge of the panel body and the door body. Recently, however, there have been many improper acts such as peeping through this upper space or secretly photographing using a camera or video, which has become a social problem. Therefore, in order to avoid this, for the panel body, a configuration has been proposed in which a concave groove-shaped portion is formed at the upper end portion of the panel body, and a hanging piece from a ceiling rail provided on the ceiling surface is inserted into the concave groove-shaped portion to close it (see, for example, Patent Document 1). However, for the door body, a configuration is adopted in which the door body is supported via upper and lower hinge fittings (for example, gravity hinges) on the side edge portion on the opening side of the panel body so as to be openable and closable about a vertical axis (see, for example, Patent Document 2). For this reason, a gap remains between the upper edge portion of the door body and the ceiling surface, and it has been impossible to prevent improper acts such as peeping through this gap.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when the door body is supported so as to be openable and closable using a hinge fitting as in the prior art, the upper hinge fitting is an inverted L-shaped one having a vertical piece portion and an upper piece portion, and the vertical piece portion is attached to the hanging-side edge portion of the panel body. A hinge shaft protruding downward from the upper piece portion is rotatably supported around a vertical axis by a hinge receiver provided at the upper edge portion of the door body. And when attaching the upper edge portion of the door body to the panel body using such an inverted L-shaped upper hinge fitting, assuming that the upper edge of the panel body has an upper space separated from the ceiling surface and the upper space is covered by a ceiling rail, the panel body is arranged lower than the ceiling surface. Therefore, for the door body as well, an upper space with the upper edge separated from the ceiling surface must be provided. However, since the door body moves open and closed, it is impossible to block the upper space with a ceiling rail like the panel body, and it remains open, making it difficult to prevent improper acts such as peeping. These are the problems to be solved by the present invention.

Means for Solving the Problems

[0005] The present invention was created for the purpose of solving these problems in view of the above circumstances. The invention according to claim 1 is a door body support structure for a panel body in which a door body is rotatably supported around a vertical axis via upper and lower hinge fittings at the hanging-side edge portion of the panel body standing upright between the floor surface and the ceiling surface.

As a result, the upper piece portion can be attached in a state where it is close to the ceiling surface, the upper edge portion of the door body is made to face the ceiling surface in proximity, and the gap between the upper piece portion and the ceiling surface is narrowed, thereby preventing improper behaviors such as peeping. Moreover As a result of the upper half portion of the upper hinge fitting protruding upward from the upper edge of the attachment surface portion provided on the panel body being attached to the attachment piece portion of the auxiliary fitting provided on the panel body, the attachment of the upper hinge fitting to the panel body side is ensured, and it is possible to avoid the attachment strength being impaired. Furthermore The auxiliary fitting is fixed to the straddle piece portion of the upper frame provided on the panel body. As a result, the upper hinge fitting is attached not only to the attachment surface portion of the panel body but also to the upper frame of the panel body via the auxiliary fitting, and thus the attachment with increased strength is achieved.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, 1 is a toilet booth, and a plurality of the toilet booths 1 are connected in series on the left and right, and include a front panel body (corresponding to the "panel body" of the present invention) 2 that surrounds the toilet T, a depth panel body 3, and a door body 4 that opens and closes an opening E formed between the left and right front panel bodies 2. The door body 4 is attached to the suspension side edge of the front panel body 2 so as to be freely openable and closable. The front panel body 2 has a core material 2b such as a honeycomb core material filled between the front and back plates 2a, and is framed in a state where it is surrounded on all four sides by left and right vertical frames in the vertical direction (only the vertical frame 2c on the suspension side is shown in the drawing) and upper and lower frames in the horizontal direction (only the upper frame (upper horizontal frame) 2d is shown in the drawing). Regarding the lower edge of the front panel body 2, the gap (lower space) between it and the floor surface F is blocked by a floor rail (lower rail) 7 attached to the floor surface F. This structure is known (see, for example, the above-mentioned Patent Document 1), and its details are not directly related to the present invention, so they are omitted.

[0009] On the other hand, an upper frame 2d is provided at the upper edge of the front panel body 2 as described above. The upper frame 2d is formed with a concave groove portion 2e by a spanning piece portion 2f and leg piece portions 2g whose front and rear edge portions of the spanning piece portion 2f extend upward. The edge portion on the suspension side of the upper frame 2d is formed in a frame structure in a state of abutting against the upper edge portion of the vertical frame 2c on the suspension side from the inner side in the left-right direction. In this case, the vertical frame 2c is set so that its upper edge is at the same height as the upper edge of the front and rear leg piece portions 2g of the upper frame 2d. Incidentally, the front and rear leg piece portions 2g of the upper frame 2d in the present embodiment are in an inverted L shape with the upper edge portion bent inward in the front-rear direction, and the front and back plates 2a are bent so as to reach the bent upper edge portion of the leg piece portions 2g. The surface portion bent so as to reach the upper edge portion of the leg piece portions 2g of the front and back plates 2a constitutes the upper edge 2h of the front panel body 2. There is a gap (inter-column space, upper space) S between the upper edge 2h of the front panel body 2 and the ceiling surface H. On the ceiling surface H, the spanning piece portion 8a of the U-shaped ceiling rail 8 is attached via screws 8b, and the hanging piece 8c hanging from the spanning piece portion 8a fits into the concave groove portion 2e to block the gap S. By doing so, it is configured so that improper acts such as peeping through the gap S between the front panel body 2 and the ceiling surface H cannot be carried out.

[0010] On the other hand, the vertical frame 2c has a U-shaped cross-section with an opening on the inner side in the left-right direction and a cross-piece portion 2i on the outer side. At the suspension end side, on the vertical frame 2c on that side, the left and right edge plate portions 2j of the front and rear panel plates 2a protrude toward the door body 4 side (outer side in the left-right direction) from the vertical frame 2c, and are inclined inward in the left-right direction from the left and right edge plate portions 2j, and a central plate portion 2k is formed to face the vertical frame cross-piece portion (Corresponding to the "attachment surface" of the present invention.) 2i in a parallel state with a gap therebetween. By doing so, the edge portion of the suspension end edge of the front panel body 2 is formed. However, an opening 2l is notched and formed at the upper end portion of the central plate portion 2k. On the other hand, the cross-piece portion 2i of the suspension end vertical frame 2c is notched so that the upper end edge 2n is at the same height as or slightly lower than the upper frame cross-piece portion 2f (in a state where it does not protrude above the upper frame cross-piece portion 2f), thereby forming a notch portion 2m. A reinforcing plate 9 is provided at a portion below the notch portion 2m of the cross-piece portion 2i in a state where the upper end edge does not protrude above the upper frame cross-piece portion 2f. The outer surfaces in the left-right direction of the reinforcing plate 9 serve as the attachment surfaces of the vertical piece portions 5a (corresponding to the "attachment surfaces" of the present invention).

[0011] Reference numeral 10 denotes an auxiliary fitting for attaching the upper hinge fitting 5 to the suspension end portion of the front panel body 2. The auxiliary fitting 10 is incorporated into the concave groove portion 2e in a state where the fixing piece portion 10a, which is the lower piece of the auxiliary fitting 10, abuts against the upper frame cross-piece portion 2f, and the fixing piece portion 10a is attached to the upper frame cross-piece portion 2f via a screw 10b, thereby being attached to the upper end edge portion of the front panel body 2. The fixing piece portion 10a extends outward in the left-right direction (suspension end side), and from the extended end edge portion 10c, a first attachment piece portion 10d is bent upward in a state where it is flush with the reinforcing plate 9, protruding outward in the left-right direction from the notch portion 2m of the vertical frame cross-piece portion 2i. In the present embodiment, the upper end edge of the first attachment piece portion 10d is set to be substantially at the same height as the upper end edge 2h of the front panel body 2 (in the present embodiment, the attachment piece portion 10d is slightly higher).

[0012] On one hand, the upper hinge fitting 5 has an inverted L shape with a vertical piece 5a and an upper piece 5b. The vertical piece 5a is attached to the front panel body 2 side, and the hinge shaft 5c provided on the upper piece 5b is incorporated into the hinge receiver 11 provided on the upper end face portion 4b of the door body 4. With this attachment configuration, the door body 4 is pivotally supported such that the upper end side is rotatable about the hinge shaft 5c as the vertical axis. And the attachment of the vertical piece 5a to the front panel body 2 side in this case is executed as follows.

[0013] The upper hinge fitting 5 is attached to the reinforcing plate 9 and the first attachment plate portion 10d via screws 5d in a state where the lower half side portion (lower side portion, lower half portion) of the vertical piece 5a abuts against the reinforcing plate 9 and the upper half side portion (upper side portion, upper half portion) abuts against the first attachment piece portion 10d. By attaching the upper hinge fitting 5 in this way, the upper piece 5b of the upper hinge fitting 5 is attached in a state of being located above the upper end edge 2h of the front panel body 2 and being close to and facing the ceiling surface H. As a result, the gap (upper space) X between the ceiling surface H and the upper end face portion 4b of the door body 4 is made narrower to prevent peeping and other improper acts.

[0014] Furthermore, on the auxiliary fitting 10, a second attachment piece portion 10e is bent and formed upward from one end edge portion in the front-rear direction of the fixed piece portion 10a. The second attachment piece portion 10e extends above the panel body upper end edge 2n in a state of abutting against the inner surface of one of the pair of hanging pieces 8c fitted in the concave groove-shaped portion 2e, and is configured to be attached to the hanging piece 8c via a screw 10f at the protruding portion of the second attachment piece portion 10e.

[0015] In the present embodiment configured as described above, when the door body 4 is pivotally supported on the front panel body 2 via the upper and lower hinge fittings 5 and 6 so as to be openable and closable, for the upper hinge fitting 5, a vertical piece portion 5a attached to a reinforcing plate 9 which is an attachment surface at the hanging end edge portion of the front panel body 2, an upper piece portion 5b bent upward from the upper end of the vertical piece portion 5a toward the upper end surface portion 4b of the door body 4, and a hinge shaft 5c protruding downward from the upper piece portion 5b are provided. Then, the upper end portion of the door body 4 is incorporated into a hinge receiver 11 provided on the door body 4, and is supported so as to be rotatable about the vertical axis. In this case, by attaching the lower half portion of the vertical piece portion 5a to the reinforcing plate 9 in a state where the upper half portion of the vertical piece portion 5a protrudes above the upper end edge of the reinforcing plate 9 which is the attachment plate surface, the upper piece portion 5b can be brought close to and opposed to the ceiling surface H, and the gap X between the upper end surface portion 4b of the door body 4 and the ceiling surface H can be made narrower. As a result, it is possible to prevent improper acts such as peeping through the gap X.

[0016] Moreover, in this case, an auxiliary fitting 10 having a first attachment piece portion 10d protruding above the upper end edge of the reinforcing plate 9 is attached to the panel body 4. As a result of the upper half portion of the vertical piece portion 5a being attached to the first attachment piece portion 10d, the attachment of the upper hinge fitting 5 to the panel body 4 side is ensured, and although the lower half portion of the vertical piece portion 5a is attached to the front panel body 2 via the reinforcing plate 9 and the door body 4 is attached at a high position, it is possible to avoid the attachment strength being impaired.

[0017] Moreover, the auxiliary fitting 10 in which the first attachment piece portion 10d is formed has a fixing piece portion 10a attached and fixed to the straddle piece portion 2f of the upper frame 2d of the front panel body 2. Since the first attachment piece portion 10d is erected and formed from the hanging end edge portion 10c of the fixing piece portion 10a, the upper hinge fitting 5 is not only attached to the vertical frame 2c of the front panel body 2 via the reinforcing plate 9, but also attached to the upper frame 2d of the front panel body 2 via the auxiliary fitting 10, and thus an attachment with increased strength is achieved. The reinforcing plate 9 provided on the vertical frame 2c and the first attachment piece portion 10d of the auxiliary fitting 10 provided on the upper frame 2d are configured such that the outer surfaces for attaching the vertical piece portion 5a are flush with each other. As a result, even when the vertical piece portion 5a is attached to members with different vertical and horizontal directions, such as the vertical frame 2c side and the upper frame 2d side, there will be no hindrance to the attachment of the vertical piece portion 5a.

[0018] And the door body 4 is attached to the front panel body 2 via the upper hinge fitting 5 in this way. In this case, the hanging piece 8c of the ceiling rail 8 attached to the ceiling surface H fits into the groove-shaped portion 2e formed in the upper frame 2d, so that the gap S between the ceiling surface and the upper edge of the panel body is closed. In this case, furthermore, as a result of the second attachment piece portion 10e formed to stand up from at least one edge portion in the front-rear direction of the auxiliary fitting fixing piece portion 10a being attached to the hanging piece 8c, the auxiliary fitting 10 is also attached to the housing side via the ceiling rail 8, and the attachment strength of the door body 4 can be further improved. Moreover, in this case, the second attachment piece portion 10e is attached to the hanging piece 8c in a state where the hanging piece 8c abuts against the outer side in the front-rear direction. As a result, it is possible to avoid the visibility being impaired due to the second attachment piece portion 10e being hidden by the hanging piece 8c.
