Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a table leg attachment device that has a simple structure and can be easily and firmly attached to a table.

A conventional table leg attachment device is shown in Fig. 1, in which the top surface C of leg B is attached to the corner of table
was exposed and looked unsightly.

This proposal was devised in view of the above points.According to this proposal, a leg base having a vertical plate connected to a top plate, a bottom plate, and a double-sided plate is fitted into the four corners of the table, and the top plate is fastened. A hole and a cushion support hole are provided, and an opening is provided in the bottom plate. Leg mounting brackets are fixed to the lower surfaces of both side plates at the four corners of the table, a bolt hole is provided in the center, and the bolt holes and the openings are arranged coaxially, and the tips of the legs attached to the four corners are A bolt that fits into the bolt hole and a bolt support tube that surrounds the bolt and fits into the opening are provided.

By doing this, the unsightly appearance shown in Figure 1 is avoided, and it is convenient because the cushion can be attached at the same time as the leg base is attached.The finishing of the side panels can be relatively rough because they are covered with the leg base, and the legs It has many advantages, such as better positioning, the legs can be firmly attached, and the legs themselves can be shorter.

An embodiment of the present invention will be described below with reference to the drawings.
1 and 2 indicate the side plates at one of the four corners, and both side plates are naturally assembled at right angles. 3 and 4 are grooves drilled on the inside of each side plate at positions slightly lower than the top surface.
indicates an auxiliary plate whose edges fit into each groove. Therefore, the top surface of this auxiliary plate is slightly lower than the top surface of each side plate. Reference numeral 6 denotes a sector-shaped mounting bracket with right-angled corners and is fixed to the lower surface of each side plate with screws S (only one is shown). However, there are four screws in two locations on each side plate. The mounting bracket 6 has a bolt hole 7 approximately in the center.

The leg base 8 consists of an upper plate 9, a lower plate 10, and both vertical plates 11 and 12. and both vertical plates 1
The intersections of numbers 1 and 12 form a right angle. However, the distance between the inner surface of the upper surface plate 9 and the upper surface of the lower surface plate 10 is slightly larger than the distance from the upper surface of both side plates 1 and 2 to the mounting bracket 6.

Screw holes 13 and 14 in the top plate 9 of the leg base 8
and a cushion support hole 15. A cushion 15A is fitted into this support hole 15.

The respective screw holes 13 and 14 are the mounting screw holes 1 on the upper surfaces of both side plates 1 and 2 when the leg base 8 is attached to both side plates.
6 and 17 are facing each other. Bottom plate 1
0 has an opening 18 facing the bolt hole 7 of the mounting fitting 6.

Numerals 19 and 20 are grooves similarly provided in the lower plate 10, which are not shown, but serve as relief grooves for mounting screws on the side plate of the mounting bracket 6.

Reference numeral 21 denotes a leg, and a bolt 22 is provided protruding from approximately the center of the leg, and this bolt is opposed to the bolt hole 7. A support cylinder 23 is provided around the bolt 22,
This support tube faces the opening 18 and is adapted to fit into the inner periphery of this opening.

Since the leg attachment device of the proposed table is constructed as described above, first, the attachment fittings 6 are fixed to the lower side of the side plates 1 and 2 with screws. Next, the leg bases 8 are fitted into the four corners of the table so that the inner surfaces of the upper plates 9 are in contact with the upper surfaces of the side plates, and the upper surfaces of the lower plates 10 are in contact with the lower surfaces of the mounting brackets 6. At this time, although not shown, the screws near the corners for attaching the mounting bracket 6 to the side plate fit into the clearance grooves 19 and 20, and the screws do not interfere with the attachment of the leg base 8 in any way. Further, the inner surfaces of both vertical plates 11 and 12 of the leg base 8 are in close contact with the outer surfaces of the both side plates.

After fitting the leg base 8 in this way, screw 2
4 and 25 through the screw holes 13 and 14 to the side plates 1 and 2.
The leg bases are screwed into the screw holes 16 and 17 on the upper surface of the base plate to fix the leg bases to the side plates 1 and 2.

When the leg base 8 is fixed to both side plates, the cushion 15A fitted in the cushion support hole 15 in advance
The bottom surface of the auxiliary plate 5 contacts the top surface of the auxiliary plate 5, and the top surface thereof protrudes from the top surface of the top plate 9 of the leg base 8 to receive a top plate (not shown).

Further, the openings 18 in the lower plate 10 are aligned with the bolt holes 7 in the mounting bracket 6 in the axial direction.

When attaching the leg 21 to the mounting fitting 6 in this state, the bolt 22 is fitted into the bolt hole 7 through the opening 18 and projected, and is tightened and fixed with the nut 26. At this time, the support cylinder 23 surrounding the bolt 22 fits into the opening 18 of the lower plate 10 of the leg base 8, and the leg 21
is firmly attached to the mounting bracket 6 via the leg base 8. It goes without saying that such leg bases and legs are attached to the four corners of the table.
