Description

The present invention relates to the technical field of structures for attaching gripping members, such as handles and handrails, to panel bodies that constitute wall panels or partition panels.

In general, a partition for dividing a wall surface of a building frame or an interior space may be a wall panel or partition panel formed by adjacent panel bodies on the left and right (or top and bottom), and when it is required to attach a gripping member such as a handle or a handrail to such a panel body, a method has been proposed in which the base of the gripping member is directly attached to the panel body itself via a screw material (screw) (see Patent Documents 1 and 2). However, some of such gripping members need to support the weight of a person and therefore require a certain level of attachment strength, but many panel bodies do not have the strength to support the gripping member, and not only is it practically impossible to attach the gripping member directly to such a panel body, but there is also the problem that an attachment hole is formed in the panel body.
A known structure is therefore known in which the bottom of a groove-shaped joint between adjacent panel bodies is formed from a support (base material), and a gripping member is attached to the support by screwing a screw material into the base end of the gripping member, which is supported by the surface plate of the panel body (see, for example, Patent Document 3).

JP 2004-3281 A JP 2015-94092 A Japanese Patent Application Publication No. 10-273957

However, among the conventional configurations in which the gripping member is attached to the support via a screw material, there is a configuration in which the screw material is simply screwed in while passing between the base end of the gripping member and the support that becomes the bottom of the joint groove (see Figure 2 of Patent Document 3).However, with this configuration, there is no material that directly reinforces the area between the joint material and the support, so there is still a problem in that it is difficult to firmly attach the gripping member.
For this reason, one proposed structure is to provide a reinforcing member on the support that forms the bottom of the groove of the joint, extending to the open end of the joint, and to screw a screw into the reinforcing member, thereby ensuring the attachment strength of the gripping member (see Figures 8 and 10 of Patent Document 3).
However, with this method, if one tries to retrofit a gripping member to a support that does not have a reinforcing member, the support itself must be replaced with one that has a reinforcing member, or additional work (construction) must be required to attach a reinforcing member to the support, resulting in poor workability. These are the issues that the present invention aims to solve.

The present invention has been made in view of the above-mentioned circumstances and with the objective of solving these problems. The invention of claim 1 provides a method for attaching a gripping member via a mounting fixture to adjacent panel bodies flush with each other via a groove-shaped joint, the gripping member having a base end portion widened so as to span between the surface sheets of the adjacent panel bodies via the joint, the mounting fixture having a mounting portion that abuts against the surface sheets in a state spanning between the surface sheets of the adjacent panel bodies via the joint and that is widened so that the base end portion can be attached, and a mounting portion that is fitted into the joint in a state protruding from the mounting portion and attached. and an insertion portion attached to the mounting portion via a screw member for the insertion portion screwed into the base material supporting the back surface side of the panel body, the insertion portion inserted into the joint is attached and fixed to the base material together with the mounting portion in a state of abutting against the surface panel of the adjacent panel body via the joint by screwing a screw member for the base material penetrating the insertion portion from the mounting portion side into the base material supporting the back surface side of the panel body, and the gripping member is attached and fixed to the mounting fitting by screwing the screw member for the mounting portion into the mounting portion from the base end side.
The invention of claim 2 provides a structure for attaching a gripping member to a panel body according to claim 1, characterized in that the fitting portion is adapted to allow the screw member to fit loosely therein and has a tip that abuts against the base material.
The invention of claim 3 is a mounting structure for a gripping member to a panel body described in claim 1 or 2, characterized in that the insertion portion is configured elongated to correspond to the longitudinal direction of the joint portion, and the mounting hardware is screwed to the base material at at least two points in the longitudinal direction of the insertion portion.
The invention of claim 4 is a mounting structure for a gripping member to a panel body described in any one of claims 1 to 3, characterized in that the gripping member is elongated and both end edges are attached via mounting fittings.
The invention of claim 5 is a structure for attaching a gripping member to a panel body described in any one of claims 1 to 4, characterized in that the panel body is a panel body that constitutes a partition panel, and the base material is erected in the indoor space and supports the back side of the panel body.
The invention of claim 6 is a structure for mounting a gripping member to a panel body described in any one of claims 1 to 4, characterized in that the panel body is a panel body whose back side is supported by a base material provided on the main body side to form a wall panel.
The invention of claim 7 is an attachment structure for a gripping member to a panel body described in any one of claims 4 to 6, characterized in that the long-shaped gripping member is attached via mounting fittings to joints whose both end edges are spaced apart on the left and right.
The invention of claim 8 is an attachment structure for a gripping member to a panel body described in any one of claims 4 to 6, characterized in that both end edges of the long gripping member are attached above and below the same joint portion via mounting fittings.

By adopting the invention of claim 1, when the gripping member is attached to the panel body using a mounting bracket, the insertion portion protruding from the mounting part to which the base end of the gripping member is attached is inserted into a groove-shaped joint portion, and the mounting bracket is attached and fixed to the base material via a screw material inserted into the insertion portion. As a result, the insertion portion becomes a reinforcing member and can be firmly supported on the base material that supports the back side of the panel body. Even when the gripping member is attached as an add-on, the gripping member can be firmly attached using the existing base material as it is, without the need to perform work such as replacing the base material.
By adopting the invention as defined in claim 2, the gripping member can be attached with the tip of the insertion portion in contact with the base material, thereby making it possible to easily attach the gripping member in a state of superior strength.
By adopting the invention of claim 3, the insertion portion is elongated in correspondence with the length of the joint portion, and is fixed with screws at least at two points in the longitudinal direction, so that the insertion portion can be reliably attached without being displaced.
According to the invention as defined in claim 4, even if the gripping member is long, it is possible to reliably achieve a strong attachment by effectively utilizing the base material.
According to the invention as defined in claim 5, the gripping member can be securely attached even when the panel body is a partition panel that divides an interior space.
According to the sixth aspect of the present invention, the gripping member can be attached reliably even if the panel body is a wall panel.
By adopting the inventions of claims 7 and 8, when the gripping member is long, it can be attached to joints spaced apart on the left and right, or above and below the same joint, making it possible to accommodate a variety of attachment methods for the gripping member.

FIG. 1A, 1B, 1C, and 1D are a front view, a side view, a plan view, and an exploded side cross-sectional view of the mounting bracket. 13A and 13B are a front view and an enlarged cross-sectional side view of a partition panel showing a vertical handrail attached thereto.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a partition panel provided to separate an indoor space, and the partition panel 1 is constructed using front and back panel bodies 2 which become the front and back (front and back) panels of the partition panel 1. The panel bodies 2 are arranged so that adjacent ones on the front and back surfaces are connected flush (in a continuous manner) in the left-right direction with groove-shaped joints M as described later.
The panel body 2 is constructed using a surface plate 3 and a board plate 4 made of a material such as gypsum, calcium silicate, calcium carbonate, etc., which is fixed (glued) to the inner surface (rear surface) of the surface plate 3. The pair of front and back panel bodies 2 are arranged opposite each other with a gap between them in the front and back (front to back) directions, and their rear surfaces are attached and supported by a base material 5 which acts as a vertical support provided in the gap.

Specifically, the surface plate 3 of the panel body 2 has edge portions 3a that are folded back inward in the front-back direction in a U-shape at the left and right edge portions of the panel body 2, and a locking hole 3c is formed in the inner piece 3b of the edge portion 3a, and the locking hole 3c is configured to lock in place by fitting one end 6c of the locking metal fitting 6 in a freely insertable and removable manner.

The base material 5 has a C-shape with a straddling portion 5a, a leg portion 5b, and a tip portion 5c bent from the leg portion 5b toward the opposite side, and is erected between the floor and ceiling surfaces with the leg portion 5b facing in the front-to-back direction. The other end portion 6b of the locking fitting 6 is inserted freely into the locking hole 5d formed in the leg portion 5b, and is configured to lock into the locking groove 6a.

The procedure for attaching the panel body 2 to the base material 5 may be, for example, to engage the fastening fitting 6 with the fastening hole 5d provided in the base material 5, and then to fit the fastening fitting 6 into the fastening hole 3c provided in the surface material 3 of the panel body 2, thereby assembling the partition panel 1 with the back side of the front and back panel body 2 supported on the base material 5. It goes without saying that the mounting structure of the panel body 2 to the base material 5 is not limited to that of this embodiment, and any commonly known mounting structure may be appropriately adopted as necessary.
When the panel bodies 2 are attached adjacent to each other on the front and back sides in this manner, a vertically long concave groove-shaped joint portion M is formed between the edge portions of the panel bodies 2 adjacent to each other, with the leg portion 5b of the base material 5 forming the bottom surface of the groove and the tip piece portion 3d of the edge portion 3a of the front panel forming the side surface of the groove, which can be seen (visually recognized) from the outside.

An example will be described in which a handrail 7 that is long in the left-right direction is attached to the panel body 2 on the front side (one of the front or back surfaces) of a partition panel 1 constructed in this manner using a mounting bracket (fixing device) 8.In this case, a flange-like base end 7a with an arc (disk) shape is formed on both the left and right ends of the handrail 7, and the base end 7a is wide enough to span (reach) between the surface panels 3 of adjacent panel bodies 2 via the joint portion M.
Meanwhile, the mounting bracket 8 is configured with an attachment portion 8a corresponding to the shape of the base end portion 7a of the handrail 7, and the attachment portion 8a is configured so that it can abut the handrail base end portion 7a and be attached and fixed via a screw material (screw : screw material for attachment portion ) 9. In this embodiment, the work of attaching the handrail 7 to the mounting bracket 8 is carried out after the mounting bracket 8 is attached to the partition panel 1, as described later.

The fitting 8 is provided with an insertion portion 8b protruding from the rear surface of the mounting portion 8a, and the insertion portion 8b is formed with dimensions that fit into the mounting portion 8a (and do not protrude from the mounting portion 8a), and has a rectangular prism shape that is long and has a width that fits into the joint portion M along the long groove direction (up-down direction) of the joint portion M. The insertion portion 8b is configured so that both end portions in the long direction can be detachably attached and fixed to the mounting portion 8a via a screw material (insertion portion screw material) 10 screwed into the mounting portion 8a, and thus the insertion portion 8b can be replaced with one that corresponds to the groove depth and groove width of the joint portion M so that the tip 8c abuts against the base material leg portion 5b that becomes the groove bottom of the joint portion M, as described below.

The mounting bracket 8 is then attached to the base material 5 with the insertion portion 8b inserted into the joint portion M and the mounting portion 8a abutting against the surface plate 3 of the panel body 2. In this case, the back surface of the mounting portion 8a abuts (makes surface contact with) both surface plates 3 of the adjacent panel bodies 2 with the joint portion M between them. When this is done, the tip 8c of the insertion portion 8b abuts against the leg portion 5b of the base material 5, i.e., the bottom of the groove of the joint portion M, so that the insertion portion 8b of the mounting bracket 8 is received and supported by the base material 5. In this state, the screw material (screw : screw material for base material) 11 inserted from two upper and lower screw holes (formed in series in the mounting portion 8a and the insertion portion 8b) 8d arranged between the screw material 10 is loosely fitted and screwed into the base material 5, thereby allowing the mounting bracket 8 to be attached and fixed to the base material 5. Needless to say, the number and positions of these screws 10 and 11 can be appropriately changed as required.
Then, by attaching the base end 7a of the handrail 7 to the mounting bracket 8 installed in this manner via the screw material 9, as described above, the handrail 7 can be attached to the panel body 2 while being attached and supported by the base material 5.
In the drawing, reference numeral 12 denotes an upper rail attached to the ceiling surface H, and 13 denotes a lower rail provided on the floor surface F, and the base material 5 is attached in a state in which it is supported by these upper and lower rails 12 and 13. Reference numeral 14 denotes a horizontal support provided between the left and right base materials 5.

In the present embodiment configured as described above, when a handrail 7 long in the left-right direction is attached to the panel body 2 constituting the partition panel 1 using the mounting bracket 8, the fitting portion 8b, which is a component of the mounting bracket 8, is fitted into the groove-shaped joint portion M, and the mounting portion 8a is set in a state in which it abuts against the surface plate 3 of the panel body 2 adjacent to the left and right, so that the tip 8c of the fitting portion 8b abuts against the leg portion 5b of the base material 5, which forms the bottom surface of the groove of the joint portion M. In this state, the screw material 11 is loosely fitted into the screw hole 8d and screwed into the base material 5, so that the mounting bracket 8 can be attached and fixed to the joint portion M, and the base end portion 7a of the handle 7 is attached and fixed to the mounting portion 8a of the attached mounting bracket 8 via the screw material 9, so that the handrail 7 can be attached.

In this way, when the handrail 7 is attached using the mounting bracket 8, the fitting 8b on the mounting bracket 8 can be fitted into the joint M to attach and fix the handrail 7 to the base material 5. As a result, the fitting 8b acts as a reinforcing member and can be firmly supported by the base material 5 that supports the back side of the panel body 2. Even when the handrail 7 is attached later, there is no need to replace or reinforce the base material 5, and the handrail 7 can be firmly attached using the existing base material 5 as is.

Moreover, in this case, since the tip 8c of the insertion portion 8b abuts against the leg portion 5b of the base material 5, the gripping member can be easily attached in a state with superior strength.
Furthermore, the insertion portion 8b is configured to be elongated to correspond to the longitudinal direction of the joint portion M, and the mounting bracket 8 is fixed to the base material 5 at two points in the longitudinal direction of the insertion portion 8b via screw material 11, so that the insertion portion 8b can be securely attached without shifting out of position.
In this case, even if the handrail 7 is long, both end edges are attached via mounting brackets 8, which ensures strong attachment by making effective use of the base material.

Furthermore, in the above embodiment, the handrail 7 is long and has both ends attached to the joints M spaced apart on the left and right sides via mounting brackets 8, but this is not limited to this configuration, and it goes without saying that it can also be installed in a vertical position with both ends attached above and below the same joint M via mounting brackets 8, as in the second embodiment shown in Figure 9.

Furthermore, in the above embodiment, the long handrail 7 is attached to the panel body 2 in a horizontal or vertical position, but the long gripping member is not limited to being attached in two places, but may be attached in three or more places, including an intermediate portion, and the gripping member is not limited to the handrail 7, but may be a long, long object such as a handrail, handle, or armrest, and furthermore, the present invention can be implemented with a gripping member that is not limited to such long objects, but is provided in a scattered (single-point) manner, such as a grip (knob).

In the above embodiment, the panel body 2 is described as a panel body 2 for constituting a partition panel 1, and the base material 5 is described as a vertical support that is erected in the indoor space and supports the back side of the panel body 2. However, this is not limited to this, and it goes without saying that the present invention can be similarly embodied even if the panel body is a panel body for forming a wall panel by having its back side supported by a base material (vertical support or horizontal support) provided on the side wall surface of the main body.
Furthermore, when such a panel body is provided in a place with a flat floor such as a corridor or a room, and the gripping member can be attached horizontally or vertically, the present invention can be implemented as in the above-described embodiment. However, when it is necessary to attach the gripping member at an incline, for example in a staircase or entrance door, it goes without saying that the present invention can be implemented to attach the gripping member along the incline.
Moreover, the panel bodies used to form partition panels or wall panels in this manner are not limited to those with vertical joints, and the present invention can of course be implemented with those with horizontal joints.

The present invention can be used as a structure for attaching a gripping member such as a handle or handrail to a panel body constituting a wall panel or partition panel.
