Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a side leg portion of a desk or the like which is disposed on at least one side portion of a desk or a table and supports a top plate.

[0002]

[Prior art]

 The side legs of conventional desks and the like are often made of either metal or wood, but some of them are made of metal, for example, in order to maintain both strength and aesthetic appearance. There is one in which a decorative plate made of wood or synthetic resin is attached to a frame material made of wood.

[0003]

[Problems to be solved by the device]

 However, conventional components using different materials are fixed to each other by adhesives, welding, or other fixing means that is difficult to separate. There is a problem that it is difficult to separate and it cannot contribute to recycling for effective use of resources in recent years.

In view of the above problems of the prior art, the present invention makes it possible to easily assemble the decorative plate and the leg frame and to separate them easily so that they are different from each other. It is an object of the present invention to provide a structure of a side leg portion of a desk or the like that can contribute to recycling of resources when it is formed of a material.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a structure of a side leg portion of a desk or the like, which is disposed on at least one side portion of the desk or the like and supports a top plate, and has a horizontal leg rod downward facing in the front-back direction. A rectangular leg frame is formed by sandwiching a pair of front and rear intermediate columns between the rear part of the arm and the rear part of a horizontal upper arm facing in the front-rear direction, and bolting it to the inner surface of the leg frame. The edge portion of the decorative plate is fitted in the fitting groove.

[0006]

[Action]

 The edge of the decorative plate fits into the fitting groove, and the front and rear of the decorative plate are sandwiched by a pair of intermediate columns, and the upper and lower parts of the decorative plate are sandwiched by the arm and the horizontal leg rods. The side leg of a desk or the like can be easily assembled by tightening the bolt and the horizontal leg rod, and the decorative plate and other components can be easily separated by removing the bolt. It can contribute to the recycling of resources.

【Example】

 The drawing shows an embodiment of the present invention. As shown in FIG. 2, the desk has a top plate (1) between the upper ends of a pair of left and right side legs (A) which are parallel to each other. It is mounted and the curtain plate (2) is stretched between the rear ends.

At the lower end of the side leg (A), a horizontal leg rod (3) made of aluminum light alloy which faces the front-rear direction is provided at the rear portion of the upper surface with a pair of short standing front and rear portions having an insertion protrusion (4a) at the upper end. The upper portion (4) is connected to form a flat U-shaped portion (5), and two left and right first fitting grooves (6) are formed on the inner surface thereof.

A pair of left and right short arms having an insertion protrusion (8a) at the lower end are provided at the rear portions of the lower surfaces of the pair of left and right aluminum light alloy arms (7) which support the top plate (1) and which face in the front-back direction. The hanging part (8) is connected, and the downward U-shaped part (9) having the same shape and the same size as the U-shaped part (5) is vertically symmetrically formed, and the first fitting groove (6) is also formed on the inner surface thereof. A fitting groove (not shown) of the same shape and size is formed.

The horizontal leg rod (3) and the arm (7) on the same side are provided with a pair of front and rear aluminum light alloys between the front and rear rising parts (4) and the hanging parts (8) facing each other. Insert the intermediate support columns (10) and (11) into the upper and lower ends so that the protrusions (4a) and (8a) fit together, and set up the upright section (4) and both intermediate support columns (10) and (11). The U-shaped part (5) and the downward U-shaped part which are connected to each other by fastening the nut (13) to the long bolt (12) which penetrates the hanging part (8) and are connected in this way. A square leg frame (14) is formed by (9) and the front and rear intermediate columns (10), (11).

Two opposing second fitting grooves (15) having the same cross-sectional shape as the first fitting groove (6) are also formed on the facing surfaces of both the intermediate columns (10) and (11), and the upper and lower first fitting grooves (15) are formed. Two rectangular annular grooves (16) are formed on the inner peripheral surface of the leg frame (14) so as to be continuous with one fitting groove (6).

A locking groove (17) oriented in the up-down direction is formed on the facing surface of the rear intermediate column (11) facing left and right.

At the time of assembly, the leg frames (14) are closed by incorporating a wooden decorative plate (18) in the outer annular groove (16), and the inner annular groove (16) is closed in the outer plate (18). ), A wooden decorative plate (19) having a shorter vertical length is incorporated, and an arcuate notch (20) is cut from the bottom at the center of the lower end of the inner decorative plate (19).

In the side leg portion (A) of the present invention having the above-mentioned structure, the upper end is connected by the connecting rod (21), the top plate (1) is mounted, and the locking groove of the rear intermediate support column (11). A curtain plate (2) is locked between (17) to form a desk.

In the above-mentioned embodiment, the leg frame (14) is made of aluminum light alloy, but the leg frame (14) can be made of other metal, synthetic resin or wood, and the decorative plate ( 18) (19) can be made of synthetic resin, metal or the like in addition to wood.

Since the inner decorative plate (19) can be raised and lowered in a short size, the cords such as the electronic devices and the lighting fixtures on the top plate (1) can be attached to the internal and external decorative plates ( 19) It can be passed through between (18) and can be wired neatly, can store extra length cords, etc., and if a large connector is attached to the cords, the inside decorative board ( Wiring can be done using the arcuate notch (20) in 19).

In some cases, the present invention may incorporate only the outer plate 18 with one annular groove 16.

[0018]

[Effect of device]

 According to the present invention, the following effects can be achieved. (a) With the decorative plate at the center, the front and rear of the plate are sandwiched by the intermediate stanchions, and the upper and lower parts are sandwiched by the arm and the horizontal leg rod. It can be assembled and each component can be easily separated simply by removing the bolt.

(B) Therefore, even if the decorative plate and the member forming the leg frame are made of different materials, each component can be easily separated from each other by simply removing the bolt when the desk or the like is discarded. Since the materials can be sorted according to the material, it can contribute to recycling and effective use of resources.

(C) Further, when the decorative plate is damaged or dirty, it can be easily replaced with a new one.

(D) By disposing a pair of left and right decorative plates in the leg frame, the cords of electric equipment can be housed therein (invention according to claim 2).

(E) In the case of the above (d), if the inner decorative plate can be slid up and down with respect to the leg frame, the cord can be taken in and out more easily (the invention according to claim 3). .
