[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk used for a work table or the like using a foldable pipe leg.

[0002]

2. Description of the Related Art Many conventional desks with folding legs require time and effort for raising and lowering, poor stability when standing up, and poor appearance when folded.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to obtain a table with a pipe leg which can be easily turned upside down, has good stability when standing up, and has a good appearance when folded. .

[0004]

In order to achieve the above object, a folding table with folding legs according to the present invention is provided on the lower surface of both ends of a front and rear U-shaped shaft rod held up and down on the left and right sides of the table board. The upper ends of the pipe legs are fixed to each other, and the middle part of the V-shaped support rod is held near the center of the table board, and the left and right ends of the rod are provided on a horizontal frame provided between the front and rear pipe legs. It is formed by being inserted into

[0005]

[Work] When the pipe legs of the desk of the present invention are raised, the front and rear pipe legs are united to stand upright on the lower surface of the desk via a U-shaped shaft, and both ends of the V-shaped support rod are placed on the horizontal frame. When it is inserted into the seat, the upright position of each leg is secured.

When the V-shaped support rod is removed from the seat and the left and right pipe legs are tilted, the U-shaped shaft is raised, and each pipe leg is held on the lower surface of the table board in a state parallel to the table board.

FIG. 1 (A) is a front view of the right half of a folding table with folding legs according to the present invention (the left half is symmetrical with the right half). 1B is a bottom view, FIG. 2 is a right side view, and FIG. 3 is a front view when the pipe legs are folded.

In the drawing, reference numeral 1 denotes a table board, and a bearing 2 having an axis in the front-rear direction is mounted in the vicinity of the front, rear, left and right corners of the board, and both ends a, a of a round bar are formed between the front and rear bearings to be bent to one side. The intermediate portion b of the U-shaped shaft bar 3 is rotatably held, and the upper end of the pipe leg 4 is fixed to the outer end of the lower surface of each shaft bar by means such as welding or soldering. The middle part is connected by a horizontal rod 5.

Separately, a small bearing 6 having a longitudinal axis is mounted near the center of the lower surface of the table 1, and the intermediate portion c of the V-shaped support rod 7 is rotatably held by the bearing. d, d are inserted into front and rear receiving holes provided at both ends of the U-shaped receiving seat 8 attached to the upper surface of the horizontal rod 5, and the inserted state is confirmed by the pressure to expand to the outside of the end of the supporting rod. It is made to carry.

In particular, a double pipe 11 having an adjusting hole 12 as shown in FIG. 1C is used as a pipe leg, and the applicant has filed a utility model registration on April 27, 1993 with the adjusting hole. When the round bar bent body 13 in which the engagement portion b with the outer tube is formed at the outer end of the linear insertion portion a used for the locking device of the pipe leg is used, the height of the leg can be easily adjusted and the leg can be folded. The shape of is adjusted and it is more favorable.

[0011]

[Effects of the Invention] The folding leg desk of the present invention makes it easy to raise and lower the pipe legs easily and accurately, and maintains a strong three-dimensional structure in the standing position. And so on are accommodated inside the left and right U-shaped shaft bars which are in the upright state.
