Description

[Detailed Description of the Invention] The present invention relates to a support leg mounting structure for a table or the like.
In other words, the upper part of the supporting leg can be reliably, quickly and easily assembled to a table or chair, etc., and even if the supporting leg has a variety of shapes such as square or round cross sections, it can be easily assembled. The object of the present invention is to provide a device that is robust, can be easily disassembled and assembled, has a simple structure, is easy to manufacture, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a perspective view of the table, with 4 on deck 2.
Connecting metal fittings A are installed on the lower surface of each corner side, and the thin upper surface 8 formed above each connecting metal fitting A made of zinc die-casting is joined to the lower surface of the deck 2, and a screw is inserted through the upper surface 8. 9 into the deck 2 to fix the connecting fittings A, and each connecting fitting A
Both ends of the connecting pipe 11 are connected to the lower surface of the deck 2 to the opposing connecting rods 10, 10 of the adjacent connecting fittings A, A, with both connecting rods 10, 10 integrally protruding from both sides of the connecting fittings A, 10 in the right angle direction. are configured by fitting and fixing them.

The connecting fitting A has a triangular hole 3 in the shape of a regular square with three corners A, B, and C, and a cross-sectional shape in which one corner and a portion of both sides thereof are missing. A concave portion 4 is formed in a row on the side of the cut-out side of the triangular hole portion 3 and the concave portion 4 is opened downward, and a tapered surface 5 is formed on the inner surface of the concave portion 4. , the upper surface 8 above the end side in the recess 4
A screw hole 12 penetrating in the vertical direction is formed in the thick wall portion 8a on the end side.

The upper part of the support leg 1a made of a perfect circular pipe is fitted into the triangular hole 3 of the connecting fitting A from below, and the tightening body B is fitted into the recess 4 from below, but the tightening A supporting leg 1 is attached to the side surface on one side of the body B.
A curved concave surface 7 that can be bonded to the outer peripheral surface of the clamping body B is formed, and a tapered surface 6 that can be bonded to the tapered surface 5 of the concave portion 4 is formed on the side surface of the clamping body B excluding the concave surface 7. A hollow-shaped insertion hole 13 into which the bolt C can be inserted with some play is formed inside the bolt C in the vertical direction, and the head 14 of the bolt C is fitted into the lower part of the tightening body B below the insertion hole 13. A hole 15 with a large diameter that can be fitted is formed, and the height of the tightening body B is formed to be shorter than the depth of the recess 4.

Figures 9 to 11 show another embodiment in which the supporting leg 1b is made of a regular square square pipe, and the clamping body B is formed in the same manner as the previous one as indicated by the same reference numerals. , the concave surface 7 is formed into a square shape so as to fit into the corner surface of the support leg 1b.

Moreover, FIGS. 12 to 14 show still another embodiment, in which the support leg 1C is made of a circular pipe, and the clamping body B is formed in the same manner as the above one, as indicated by the same reference numerals. However, the concave surface 7 is formed into a deep concave curve so that it can fit into the curved outer peripheral surface of the supporting leg 1b.

Therefore, when attaching the support leg 1a made of a perfect circular pipe, the upper part of the support leg 1a is fitted into the hole of the connecting fitting A, and the concave surface 7 is joined to the outer peripheral surface of the support leg 1a, and the tapered surface 6 is Fit the tightening body B into the recess 4 so as to join it to the tapered surface 5, screw the tip of the bolt C inserted into the insertion hole 13 into the screw hole 12, and rotate the bolt C from below using a tool. Then, while the bolt C moves inside the screw hole 12 with the head 14 of the bolt C fitted in the hole 15, the tightening body B gradually enters the recess 4 and is tightened by sliding on the tapered surface 6. The attachment body B is fitted in a wedge shape, and the concave surface 7 strongly presses the support leg 1a, so that the support leg 1a
The two outer circumferential surfaces of a are pressed against the surface between the corners A and B of the triangular hole 3 and the surface between the corners B and C and are fastened and fixed, so that each supporting leg 1a The upper part of can be attached to the connecting fitting A.

Further, the support leg 1a can be removed by simply loosening the bolt C.

In the case of another embodiment shown in FIGS. 9 to 11, the concave surface 7 of the clamping body B is fitted into the corner of the support leg 1b, and the outer peripheral surface of the support leg 1b is connected to the triangular hole of the connecting fitting A. In the case of other embodiments shown in FIGS. 12 to 14, the concave surface 7 is fitted to the outer peripheral surface of one side of the support leg 1C, and the outer peripheral surface of the other side is fitted to the triangular hole. It can be attached in contact with two surfaces of the section 3.

In this way, the present invention uses a connecting fitting that is fixed to the lower part of the deck of a table or the lower part of the seat of a chair. A hole is formed in the vertical direction, and a tightening body is fitted in a concave portion extending to the side of the triangular hole that is the missing side so that the bolt can be tightened. Since the clamping body is installed and configured so that it can be assembled and fixed by pressure contacting the side surface of the upper part of the supporting leg, the upper part of the supporting leg is fitted into the triangular hole and the tightening body is tightened with bolts. The support leg can be assembled to the connecting fitting reliably, quickly and easily by pressing the support leg, and even if the support leg has a variety of shapes such as square or round cross sections, it will fit securely into the triangular hole. It can be easily assembled by pressing the clamping body together, supporting legs of various shapes can be assembled using the same connecting metal fittings, it is robust and can be assembled easily by disassembly, and the structure is simple and easy to manufacture. It has the advantage of being easy and suitable for implementation.
