Description

[Detailed description of the invention] The present invention relates to a support leg device used for desk furniture, tables, etc. In particular, the support leg device is formed of a synthetic resin that is easy to mold and can be designed into any shape, and is compatible with the frame. In addition to sufficiently reinforcing the screw fixing portion, sink marks occurring on the outer surface of the support leg are reduced.

Recently, so-called furniture-style kotatsu have been commercialized, and these kotatsu are made of solid wood with a rich tone, such as plain wood, giving it a luxurious feel.

However, as mentioned above, the use of expensive solid wood not only increases the product price, but also increases the weight and makes handling difficult.

For this reason, frames and support legs made of synthetic resin using white, black, or brown dyes have been proposed, aiming for a wood grain effect, and are characterized by light weight and a high class quality similar to that of solid wood. However, in the case of excessive weight, the support leg is made of synthetic resin and may break at the threaded fixation part with the frame, or the multiple reinforcing bars provided to reinforce the threaded boss part of the support leg may break. Sink marks appeared on the outer surface of the support legs, creating an unsightly defect.

The present invention improves the above points and will be explained with reference to the drawings. 1 is a frame 3 made of synthetic resin or wood and having right-angled corners 2 on one side (four corners);
is a triangular mounting bracket screwed and fixed to the lower surface of the corner portion 2 with machine screws 4, 4, etc., which will be described later and extends between the frames of the corner portion 2 and protrudes inward from the frame. A mounting piece 5 for mounting the support leg is formed. Further, this mounting piece 5 has a hole 5' formed therein. Reference numeral 6 denotes a prismatic supporting leg made of synthetic resin that supports the corner portion of the frame 1, and four side walls 6a, 6 forming a prismatic shape.
b, 6c, 6d and upper surface corner portions 6e, 6f,
A boss 7 corresponding to the mounting piece 5 is provided at an eccentric position near one corner 6e of 6g and 6h, and a screw 8 projecting upward is fixed to the boss. 9, 9, 9, 9... are the boss 7 and the side wall 6
A, 6b, 6c, and 6d have a plurality of reinforcing bars that integrally connect the corner portion sides, and the boss side of the reinforcing bars is thick and the side wall side is thin. The closer corner 6e side has more, and the relatively far opposite corner 6g has less.
Furthermore, the leading end side of the reinforcing bar connected to the surface side of the side wall is connected at right angles to the side wall. 1
0, 10, and 10 are pins integrally provided on the upper surface of the reinforcing beam at appropriate locations, and 11 is a bottom wall 12 and an L-shaped cover piece 13 on the top surface that is connected to the bottom wall and extends perpendicularly.
13, the bottom wall is provided with a through hole 14 at an eccentric position through which the boss 7 passes, and small holes 15, 15 through which the pins 10, 10, 10 pass. 15 are drilled.
16 is a nut, and 17 is a washer.

Regarding the assembly order and operation,
First, attach the mounting bracket 3 to the corner 2 on the bottom of the frame 1.
While fixing the leg seat plate 11 to the upper surface of the support leg 6, insert the screw 8 and boss 7 into the through hole 14, and insert the pins 10, 10, 10 into the small holes 15, 15, 1.
Penetrates 5. After melting the pins 10, 10, 10, the corner portion 2 of the frame 1 is positioned on the upper surface of the leg seat plate 11, and the screw 8 is inserted through the washer 17 into the hole 5' of the mounting piece. At the same time, the two side walls of the frame body 1 are covered by the cover pieces 13, 13. Next, the nut 16 is screwed onto the screw 8. The support leg 6 and the frame 1 are fixed by this screwing, but as shown in FIGS. 1 and 3, the threaded part of the screw 8 is inside the corner 2 of the frame 1. The corner portion side of the support leg with many reinforcing bars is located inside the frame 1.

A cross-shaped frame having a right-angled corner on one side, and fixed to the lower surface of the corner of the frame, straddling the frames at the corner and protruding inward from the frame. It consists of a mounting bracket formed with a mounting piece, and a square support leg made of synthetic resin that is screwed and fixed to the mounting piece of the mounting bracket to support the corner portion of the frame, and the support leg has a side wall; A boss to which a screw for screwing into the mounting piece of the mounting bracket is fixed is provided at an eccentric position near the corner of the top surface, and the boss and the inner wall of the support leg are connected by a plurality of reinforcing bars that are thicker on the boss side and thinner on the inner wall side. The reinforcing bars are provided with more corners near the boss and fewer corners relatively far away, and since the bosses, reinforcing bars, and side walls are integrally molded, the reinforcing bars are attached to the frame. The boss portion of the supporting leg to be fixed is reinforced by a plurality of reinforcing bars. In addition, because the reinforcing bars have more corners near the boss and fewer corners relatively far away, and are thicker on the boss side and thinner on the inner wall leg side of the support leg, sink marks peculiar to synthetic resins are almost eliminated. Since the outer side (outer surface) of the support leg, which is prevented and is easily visible to the human eye, has a small number of reinforcing bars, even if a slight sink mark occurs, it does not cause unsightliness.
