JP 2002-291537 A JP 2003-135213 A Japanese Patent No. 3488750 (FIGS. 11 and 12)

  The horizontal bar (frame) of the support device described in Patent Document 1 is made of a square pipe material having a quadrangular cross section, and an option fixture is fixed using three surfaces of the upper surface, one side surface, and the lower surface. Therefore, there are few fixed surfaces of an option fixture, and the support area of the load of a functional member is also small.

  For this reason, a reinforcing beam is installed between the two front and rear frames, and an optional fixture is screwed to the reinforcing beam to increase the mounting strength and the support strength of the offset load applied from the functional member. There are increasing problems.

  Since the recumbent described in Patent Document 2 is made of a pipe material having a circular cross section, the mounting portion of the seat rotates around the recumbent when a large offset load is applied to the seat supported by the reed. There is a risk of moving. In order to prevent this, brackets for supporting the seat body are welded to the front and rear reeds, increasing the number of parts and the number of assembly steps.

Since the recumbent described in Patent Document 3 has a rectangular cross section and is mounted with its opposite corners facing up and down, the up and down dimensions of the recumbent and the fixing member sandwiching it from above and below Becomes large, the degree of freedom in designing the seat supported by the reed is restricted, and the space below the reed is also reduced.
In addition, since there is no flat surface on the upper surface of the reed, it is troublesome to position and attach the seat body horizontally.

  The present invention has been made in view of the above-described problems, and can increase the fixing surface of the mounting member to which the functional member can be mounted and the support area of the load, thereby firmly fixing the mounting member, and mounting after fixing. It is an object of the present invention to provide a furniture support device and a fixing structure for attaching a functional member mounting member to a side wall thereof, in which the vertical dimension of the member is small and the mounting member can be easily positioned and mounted horizontally. Yes.

According to the present invention, the above problem is solved as follows.
(1) In a furniture support device in which a plurality of portions of a horizontal surface facing in the left-right direction are supported by legs, and a functional member such as a top plate is attached to the horizontal surface with an attachment member, the cross-section of the horizontal surface The shape is a hexagon or octagon where the upper and lower surfaces form a horizontal plane.

(2) In the above item (1), the horizontal rod is a hexagonal or octagonal cross-section tube, and the upper and lower opposing surfaces in the inside are formed by at least a pair of vertical flat reinforcing ribs facing in the left-right direction. Join.

(3) A fixing structure for fixing a mounting member for attaching a functional member to a reed of the furniture support device according to the above (1) or (2), wherein the mounting member is made up of a pair of upper and lower fixing plates. These two fixing plates are fitted to the side wall from above and below and fixed by fastening means.

(4) In the above item (3), at least two recumbent ribs are provided so as to be parallel to each other, and a pair of upper and lower fixing plates in a mounting member having a large front-rear dimension are vertically mounted on the front and rear reeds It is more fitted and fixed by the tightening means.

According to the first aspect of the present invention, since the reed supported by the left and right legs has a hexagonal or octagonal cross section in which the upper and lower surfaces are flat, the fixing surface when the functional member is attached thereto is 6 Since the load supporting area of the load acting on the mounting member is also increased, the mounting strength and load bearing strength of the mounting member can be increased.
In addition, since the upper and lower surfaces of the recumbent are horizontal surfaces, the vertical dimension of the recumbent can be reduced as well as the mounting member attached to the reed and the functional member attached to the mounting member. Can be easily positioned horizontally and attached.

  According to the second aspect of the present invention, since the bending strength and torsional rigidity of the reed are increased, it is possible to support a larger load of the functional member and to function in a state where the mounting member protrudes in the front-rear direction. Even if a member is attached, the risk of twisting the reed is reduced.

  According to the invention of claim 3, the fixing work of the mounting member to the recumbent can be easily performed with the legs attached, and the recumbent is subjected to processing for fixing the mounting member. Since it is not necessary to apply anything, the attachment member and the functional member attached thereto can be easily moved in the left-right direction and adjusted by simply loosening the tightening means.

According to the invention described in claim 4, since the mounting member is fixed to the two front and rear ridges, the functional member can be stably mounted on the mounting member even in a state where the mounting member protrudes greatly in the front-rear direction. it can.
In addition, since the attachment strength of the attachment member to the recumbent arm is high, it is not necessary to connect the middle portions of the front and back recumbent members between the left and right legs with a reinforcing beam or the like, and the number of parts can be reduced.

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

  As described above, the auxiliary top plate (63) of the side table (62) is placed on the side of the top plate (26) at the upper end of the pedestal (2b) of the leg (2), that is, the support member (5). If the upper surface is provided so as to be horizontally rotatable, the auxiliary top plate (63) can be independently rotated, and the rotation range becomes large.

  That is, when the left and right auxiliary top plates (63) are largely rotated to the side, the side table (62) becomes longer in the left-right direction, so that they can be used as a work table by a plurality of workers.

  Also, if the top surface of the top plate (26) is horizontally level and flush with the top surface of the auxiliary top plate (63), it is turned inward of the auxiliary top plate (63) to the maximum position. Since the plate surface is formed, it is possible to secure a wide working area and to enlarge a mounting space for OA equipment and the like.

The present invention is not limited to the above embodiment.
A functional member may be attached to the support member (5) or the support bracket (15) as an attachment member.
