Description

  The present invention relates to a member mounting structure in which options and the like can be appropriately mounted directly or via a bracket in a narrow space existing in existing furniture or the like.

  It is common in offices to attach brackets to furniture to support options. At that time, for example, the mounting structure shown in Patent Document 1 is generally employed. Although the thing of the literature is an example which attaches a shelf support and an arm member to a shelf support | pillar, since such an attachment structure is used also for another attachment use, it is taken up here.

FIGS. 1 to 10 of the same document show that a tip claw portion provided on a bracket is inserted into an opening of a shelf column and this tip claw portion is engaged with the opening by a rotating operation. At the moving end, the base end is fitted to the opening edge so that the shelf load can be supported. On the other hand, what is shown in FIG. 11 is that the two claw portions protruding in parallel from the abutment surface of the bracket are inserted into the openings provided at the two corresponding positions of the shelf column, and are dropped as they are to open the claw portion to the opening edge. In this state, the contact surface is brought into contact with the mounting surface to support the shelf load.
Japanese Patent Publication No. 1-48006

However, in the case of the former mounting structure, since the bracket is basically engaged with the shelf column only by the rotation operation, a large inclination angle is necessary at first, and a sufficient operation space is indispensable around the periphery. For this reason, for example, when the shelf is arranged on the top plate in an integrated or combined state and it is necessary to attach the bracket to the narrow space existing between the top plate and the shelf and support the drawer, etc. Structure.

On the other hand, in the case of the latter mounting structure, since the bracket is basically engaged with the shelf column only by a sliding operation, rattling is unavoidable in the mounted state, and the claw portion is bitten into the opening to eliminate this. If the structure is combined, an operation force is required, and the extraction work is difficult.

In addition, each mounting structure uses a shelf load to prevent the bracket from being detached from the shelf column, so the bracket is limited to the mounting orientation that receives the shelf load, and the bracket is suspended from the bottom surface of the shelf. The mounting orientation to be attached cannot be adopted.

An object of the present invention is to solve these problems all at once.

In order to achieve this object, the present invention takes the following measures.

That is, in the member mounting structure of the present invention, a part of the member is engaged with the opening provided on the mounting surface, and the corresponding part of the member is fixed to the other part of the mounting surface so that the engagement is not released. A part of the member is formed with a base end portion that is tightly inserted into the opening and a tip claw portion that passes through the opening and contacts the back surface of the mounting surface. After inserting the claw part into the opening provided on the mounting surface and making it enter obliquely, the claw part is rotated in a direction in which the inclination becomes shallow, so that the tip claw part is brought into contact with the back surface of the mounting surface and the base end part is placed in the opening. It can be accommodated in a state where it cannot move to the mounting surface, and the corresponding part of the member is fixed to the other part of the mounting surface, thereby preventing the tip claw part from tilting. .

If comprised in this way, after inserting a front-end | tip nail | claw part into an opening, since the operation | movement which makes it approach diagonally can be performed substantially straightly, subsequent rotation operation | movement is required in order to accommodate a base end part in an opening. A small amount is enough. For this reason, the required operation space is much smaller than when the whole is rotated largely. In addition, the base end portion is closely accommodated in the opening to obtain a state in which the member does not rattle. In this state, by fixing other parts of the member, the mounting orientation is also limited in order to maintain the state. There is nothing to do. In addition, since the overall movement is small and the feeling of wearing is obtained when the base end portion enters the opening, it is possible to easily and reliably attach the member to the target site even by groping. It becomes possible.

In particular, the member is provided with an abutting surface that abuts the mounting surface, the base end is raised in a direction to be inserted into the opening from the mounting surface, and the distal end from the displaced part of the base end toward the back surface of the mounting surface What has extended the nail | claw part is suitable. In this case, an interference that allows the base end portion of the member to be inserted into the opening while rotating the base end portion of the member at the corner portion of the base end portion is provided so as to substantially match the inner dimension of the opening. It is preferable to provide an avoidance unit.

In order to ensure the smooth behavior of the tip claw portion with respect to the opening, the tip claw portion in contact with the back surface of the mounting surface extends the inner edge from the end of the base end portion along the back surface, and the outer edge is It is desirable that the base end portion is raised in a direction once away from the rear surface from the displaced portion, and then connected to the inner edge of the tip claw portion while drawing an arc.

As a specific embodiment, the member is a bracket for attaching an option to the attachment surface, or the member is the option itself when the option is directly attached to the attachment surface.

By adopting the above bracket-type mounting structure, it can be effectively applied to the following fixtures.

A shelf board is arranged on the top board in an integrated or coupled state, and a space is formed between the top board and the shelf board. A bracket is attached in the space with the lower surface of the shelf board as a mounting surface, and the bracket is pulled out to the bracket. Furniture with a top plate that supports options such as trays.

A storage part such as a sleeve or a rack is disposed under the top plate in an integrated or combined state, and a space is formed between the top plate and the storage part. A bracket is formed in the space with the lower surface of the top plate as a mounting surface. A furniture with a top board that supports the options such as drawers and trays.

A shelf device in which brackets are mounted in the space between the shelf plates with the lower surface of the shelf plate as the mounting surface, and options such as drawers and trays are supported on the brackets.

Since the present invention is configured as described above, the bracket and other members can be easily and securely attached even in a narrow space, the mounting state is not loose, and the mounting orientation can be freely selected. It is possible to provide a new and useful member mounting structure.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In the member mounting structure of this embodiment, as shown in FIG. 1, the shelf 2 is arranged in a coupled state on the ceiling 1, and a space S is formed between the ceiling 1 and the shelf 2. This is applied to the shelf A as a furniture. The top plate 1 is arranged facing each other, and the shelf plate 2 is installed between the side plates 3 arranged at the boundary portion as a shared one.

As shown in FIGS. 2 and 4, a slit 21 a that opens is provided on the lower surface 21 of the shelf 2 that is a mounting surface, and a part of the bracket 4 is engaged with the slit 21 a and the engagement is released. The corresponding portion of the bracket 4 is fixed to the fastener mounting hole 21b provided in the other portion of the mounting surface 21 by using the fastener 5 so that the rail 7 is attached to the bracket 4 and the optional drawer 6 is provided. (See FIGS. 1 and 8).

The shelf board 2 is made of steel, and is attached in a coupled state between the side plates 3 and 3 fixed on the top board 1, and the slits are formed on the lower surface near the end in the width direction and the lower surface at the center. 21a and a rectangular fastener mounting hole 21b are provided at a predetermined distance in the depth direction.

The bracket 4 has a contact surface 41 arranged in a horizontal state and a rail mounting surface 42 arranged in a vertical state by plastically deforming a sheet metal material as shown in FIGS. In the mounted state, the contact surface 41 is brought into contact with the lower surface 21 of the shelf board 2 as shown by a solid line in FIG. Then, integrally with the contact surface 41, a base end portion 43 that is tightly inserted into the punched portion of the slit 21a, and a tip claw portion that passes through the slit 21a and contacts the back surface 21x of the mounting surface 21 44 is formed by plastic deformation. In the case of this embodiment, the tip claw portions 44 are provided in pairs at two locations on the bracket 4, whereas the base end portion 43 is closely attached so as to be fitted to the slit 21 a. In order not to increase the accuracy or the assembly accuracy, it is provided only on one of the front end claw portions 44. That is, in the predetermined mounting state shown in FIG. 6B, the base end portion 43 rises in the direction to be inserted into the slit 21 a from the mounting surface 21, that is, the portion displaced from the base end portion 43 to the bracket end side. Further, the tip claw portion 44 is extended along the back surface 21x of the mounting surface 21. The dimension X of the base end portion 43 shown in FIG. 2 substantially matches the internal dimension Y of the slit 21a, and an R portion 43a serving as an interference avoiding portion is provided at the corner portion of the base end portion 43.

That is, the bracket 4 has the tip claw portion 44 inserted into the slit 21a of the mounting surface 21 and the inner edge (lower edge) 44a as the opening edge of the slit 21a, as shown in phantom lines in FIGS. 4 and 6A. The upper edge of the base end portion 43 is applied to the opening edge on the opposite side of the slit 21a, and the neck portion of the tip claw portion 44 from the imaginary line position toward the solid line position (as indicated by the arrow in the figure) In other words, after entering obliquely to the position where the front end of the base end portion 43) abuts, as shown in FIGS. 5 and 6B, the R portion 43a is entered into the slit 21a and is imagined as indicated by an arrow in the figure. By rotating the entire bracket 4 in a direction in which the inclination becomes shallower from the line position toward the solid line position, the lower edge 44a of the tip claw portion 44 comes into contact with the back surface 21x of the mounting surface 21, and at the same time, the base end portion 43 is slit. Within 21a And thus it is closely housed in a state that can not be dynamic.

If it adds about the shape of the front-end | tip nail | claw part 44, the inner edge (lower edge) extended along the back surface 21x from the edge of the base end part 43 in the state of FIG.6 (b) attached to the back surface 21x of the attachment surface 21. FIG. 44a, the outer edge (upper edge) 44b of the tip claw 44 rises in a direction once away from the rear surface 21x from the displaced part of the base end 43, and draws a circular arc while drawing the inner edge (lower edge) of the tip claw 44. The inner edge (lower edge) 44a of the tip claw 44 is smoothly curved upward and is continuous with the outer edge (upper edge) 44b. Since the tip claw portion 44 as a whole has a rounded shape as described above, the upper edge 44b of the tip claw portion 44 is located on the right side of the slit 21a in the initial stage of the operation even more than the imaginary line state of FIG. The operation of smoothly entering the interior of the slit 21a is performed while sliding the opening edge positioned, and the lower edge 44a of the passed claw portion 44 slides the opening edge positioned on the left side of the slit 21a in the drawing. The operation of entering the back surface 21x of the mounting surface 21 from the position of the imaginary line toward the position of the solid line in FIG.

Thus, if the contact surface 41 is closely arranged along the mounting surface 21, the fastener 5 is inserted into the fastener mounting hole 21 b of the mounting surface 21 and the fastener mounting hole 41 b provided at the corresponding position of the bracket 4. The other part of the bracket 4 is fixed to the mounting surface 21, and the operation of the tip claw portion 44 being removed from the slit 21a is prohibited. The fastener 5 is made of resin. As shown in FIGS. 2 and 7, the base 51 is provided with a standing piece 52, and an elastic claw 53 is continuously provided at the tip of the standing piece 52. The elastic claw 53 is gradually brought closer to the standing piece 52 while sliding the gently curved surface 53x provided on the bracket 4 so that the fastener mounting hole 41b of the bracket 4 and the fastener mounting hole 21b of the abutting surface 21 are passed. By restoring the elastic claw 43 at the position, the engagement piece 52a provided on the standing piece 52 is brought into contact with the back surface of the mounting surface, and the base 51 is brought into contact with the lower surface of the contact surface 41 of the bracket 4 to be elastic. The claw portion 53 a provided on the claw 53 is engaged with the back surface 21 x of the mounting surface 21. When releasing, the finger can be pulled out from the fastener mounting holes 21b and 41b by placing the finger on the free end side of the elastic claw 53 and elastically deforming it toward the standing piece 52 side.

Then, the suspension type rail 7 is attached to the rail attachment surface 42 of the bracket 4 attached to the attachment surface 21 of the shelf board 2 as shown in FIG. 8, and the drawer 6 is supported by the rail 7. . Although not shown in detail, the rail 7 is a general rail that can be expanded and contracted by connecting a base end rail, an intermediate rail, and a front end rail in a telescope shape, and is attached to the rail mounting surface 42 of the bracket 4 by retrofitting. After that, the drawer 6 can be supported.

As described above, in the member mounting structure of the present embodiment, a part of the bracket 4 is engaged with the slit 21a that is an opening provided in the mounting surface 21, and the other of the mounting surface 21 is prevented from being released. The corresponding part of the bracket 4 is fixed to this part. Then, a base end portion 43 that is tightly inserted into the slit 21a and a front end claw portion 44 that passes through the slit 21a and contacts the back surface 21x of the mounting surface 21 are formed in a part of the bracket 4. After inserting the claw portion 44 into the slit 21a provided on the mounting surface 21 and entering it obliquely, the claw portion 44 is brought into contact with the back surface 21x of the mounting surface 21 by rotating in a direction in which the inclination becomes shallower. The base end portion 43 is accommodated in a state where it cannot move into the slit 21a, and the corresponding portion of the bracket 4 is fixed to the other portion of the mounting surface 21 on the base end portion 43. I am doing so.

As described above, after the distal claw portion 44 is inserted into the slit 21a, the operation of entering obliquely can be performed in a substantially straight line, so that the subsequent rotation operation is performed when the base end portion 43 is accommodated in the slit 21a. Therefore, a small amount indicated by an arrow in FIG. 5 is sufficient. For this reason, the required operation space is much smaller than when the whole is rotated largely, and even when the gap between the top plate 1 and the shelf 2 is extremely narrow in the existing shelf table or the like as shown in the figure. The drawer 6 can be effectively attached to the space S by retrofitting. Then, the base end portion 43 is closely accommodated in the slit 21a, so that a state in which the bracket 4 is not rattled is obtained. In this state, it is possible to maintain the state by fixing other portions of the bracket 4. Therefore, the mounting orientation is not limited to the illustrated embodiment. In particular, in the portion a shown in FIG. 6C, a substantially right-angled corner located at the boundary portion between the base end portion 43 and the tip claw portion 44 is an opening edge located at one end side in the longitudinal direction of the slit 21a. A corner portion that is in close contact with the corner portion from the back side and is positioned at the boundary portion between the base end portion 43 and the contact surface 41 in the portion b in FIG. Since it closely adheres to the corner portion of the opening edge from the front side, the bracket 4 has a high positioning action along the longitudinal direction. Further, as described above, the movement of the bracket 4 as a whole is small, and a feeling of wearing is obtained when the base end portion 43 enters the slit 21a. Even if the work is performed, it is possible to complete the work of attaching the bracket 4 to the target site easily and reliably.

In particular, the bracket 4 is provided with a contact surface 41 that contacts the mounting surface 21, and the base end 43 is raised from the contact surface 41 in a direction to be inserted into the slit 21 a of the mounting surface 21. The tip claw portion 44 extends from the portion thus formed toward the back surface 21x of the mounting surface 21, the size of the base end portion 43 is substantially matched to the internal dimension of the slit 21a, and the bracket is attached to the corner portion of the base end portion 43. 4 is provided with an R portion 43a that allows the base end portion 43 to be inserted into the slit 21a while rotating, so that the dimension Z (see FIG. 2) of the tip claw portion 44 is the inner dimension Y of the slit 21a. Thus, it is possible to allow the tip claw portion 44 to enter the slit 21a in a substantially straight direction from an oblique direction instead of turning. And by providing the R part 43a in the base end part 43, it is possible to make it compatible with the operation | movement rotated after an approach, and the state which closely attached the base end part 43 in the slit 21a after rotation. Become.

In particular, in a state in which the tip claw 44 is in contact with the back surface 21x of the mounting surface 21, the inner edge 44a of the tip claw portion 44 extends along the back surface 21x from the end of the base end portion 43, and the outer edge 44b of the tip claw portion 44 is obtained. Is formed in a shape connected to the inner edge 44a of the tip claw portion 44 while drawing a circular arc after rising from the displaced portion of the base end portion 43 in a direction once away from the back surface 21x. It becomes difficult to get caught on the edge, and workability can be further improved by smoothly performing the insertion / removal operation.

Further, since the bracket 4 is attached first, and then the rail 7 is attached to the bracket 4 so that the drawer 6 is supported later, not only the work is simplified but also the bracket 4 is shared or Other options such as a tray can be attached by changing the type of the bracket 4, and various functions can be added to the shelf-equipped desk A.

The specific configuration of each unit is not limited to the above-described embodiment. For example, the member to which the present invention can be applied is not limited to a bracket, and if there is no difficulty in processing etc., for example, an option itself is provided with a tip claw portion, a base end portion, etc. to prevent the mode of engaging with the slit on the mounting surface is not.

In addition, as shown in FIG. 9, a storage portion 8 such as a sleeve or a rack is disposed under the top plate 1 in an integrated or coupled state, and a relatively narrow space S <b> 2 exists between the top plate 1 and the storage portion 8. In the case of furniture B, the bracket 4 is attached in the space S2 with the lower surface 11 of the top plate 1 as an attachment surface, and the option S1 such as a drawer or a tray is supported on the bracket 4 to thereby reduce the space S2. It can be used effectively.

Furthermore, as shown in FIG. 10, even when the interval between the shelf plates 9 constituting the shelf device C is relatively narrow, the space between the shelf plates 9 and 9 with the lower surface 91 of the shelf plate 9 as the mounting surface. A new function can be easily added to the shelf space of the shelf device C by attaching the bracket 4 in S3 and supporting the option O2 such as a drawer or a tray on the bracket 4.

Furthermore, although the said embodiment illustrated the case where a member was attached by using the lower surface of a top plate or a shelf as an attachment surface, even if it is an attachment azimuth | direction where an attachment surface is a standing surface, this invention is applied effectively. The same effect as described above can be obtained.

Other configurations can be variously modified without departing from the spirit of the present invention.
