Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a support rod for supporting optional parts such as a shelf board and a pin-up board on a desk.
The present invention relates to a structure for mounting a supporting rod on a desk, which is mounted so that height can be adjusted.

[0002]

2. Description of the Related Art Conventionally, when mounting the above-mentioned optional parts on a desk, in order to cope with the type of the optional parts, the required load resistance, and the surrounding conditions,
There are cases where a plurality of types of rods having different lengths and the like are prepared as supporting rods for supporting the optional components.

Further, as a means for adjusting the height of optional parts, for example, as disclosed in Japanese Unexamined Patent Publication No. 11-123109, a lower plate-like member facing upward is fixed to a top plate of a desk. Then, the upper plate-like body was mounted so as to be vertically movable via a pair of rails fitted so as to be vertically slidable with each other, and a state in which the sliding of both rails was stopped was provided. There is something.

Further, like adjusting the height of a hanger stand or the like, by loosening the screw ring, the movable side pipe can be freely taken in and out of the fixed side pipe, and by tightening the screw ring, both pipes can be locked. There is something I did.

[0005]

However, it is not preferable to prepare a plurality of support rods having different lengths, etc., because management and storage of unused parts are troublesome and economically unfavorable. In the described device, the rail, the device for stopping the sliding of the rail, and the like are large and complicated, and are expensive.

Further, in the case of using the screw ring, it is difficult to evenly move the pair of left and right supporting rods connected to each other up and down, and when a large load is applied, the screw ring is loosened and the movable pipe suddenly moves. May contract.

In view of the above-mentioned problems of the prior art, the present invention has a simple structure with a small number of parts and can easily adjust the height of the support bar for supporting optional parts and the like. It is an object of the present invention to provide a structure for mounting a supporting rod on a desk, which has a good appearance and which can strongly support.

[0008]

According to the present invention, the above problems can be solved as follows. (1) A plurality of engaging holes are provided on the outer periphery of the supporting rod facing up and down.
A pair of substantially semi-cylindrical shapes that are formed in the longitudinal direction of the support rod at a required interval and are formed so as to face each other and unite to form a sleeve with an enlarged diameter flange that faces in the vertical direction. The support rod is sandwiched from both sides by the sleeve divided pieces of, and a projection that can be selectively engaged with the engagement hole is provided on the inner surface of at least one of the sleeve divided pieces. Fitting in the engagement hole, both sleeve divided pieces together with the supporting rod are fitted from above into a downward fitting hole provided on the upper surface of the desk, and the expanded flange is attached to the fitting hole. Abut the upper edge so that the supporting rod is supported on the desk in an upright state.

(2) In the above item (1), a projection is provided on one of the facing surfaces of the pair of sleeve divided pieces, and a recess into which the projection is fitted is provided on the other surface.

[0010]

1 to 6 show one embodiment of the present invention. The desk (1) comprises a top plate (2) and a top plate support (3) supporting the top plate (2). The top plate support (3) has cylindrical vertical legs (4) at front and rear ends. ) Of the side connecting rods (5) (5) consisting of square tubes facing the front-rear direction with the upper end fixed by welding or the like, and connecting the middle parts with the intermediate connecting rods (6) facing the left-right direction. ing.

The upper ends of the left and right rear legs (4), (4) are opened upward, and the hollow portions extending from the upper ends to the lower ends of the rear legs (4), (4) are used to support later-described optional member supporting members ( Fitting hole (7) into which a pair of left and right supporting rods (15) (15) in 14) can be fitted
(7) is formed.

Bolt insertion holes (8) are provided at two front and rear positions of each side connecting rod (5) so as to vertically pass therethrough, and the lower surface of the top plate (2) is shown in FIG. As shown by the solid line, when the top plate (2) is at the rear position covering the upper end openings of the fitting holes (7) and (7) at its rear portion, the top plate (2) is aligned with the respective bolt insertion holes (8). The four embedded nuts (9) and the top plate (2), as shown by the phantom line in FIG. 2, have their rear ends located in front of the fitting holes (7). There are four embedded nuts (10) that are aligned with the respective bolt insertion holes (8) when the front position is such that the upper end opening is exposed.

Therefore, the upper ends of the bolts (11) inserted through the respective bolt insertion holes (8) from below are attached to the front embedded nuts.
