Description

[Detailed description of the invention] [Field of industrial application] This invention relates to desks, tables, chairs, etc. (collectively referred to as "stands" in this specification) that have legs, and in particular, the structure of the legs. Regarding.

[Summary of the idea]

This idea is based on a pedestal with leg members fixed to the pedestal, in which a pair of inverted L-shaped members consisting of a horizontal part and a vertical part are slidably fitted to the end of a horizontal contact member at each horizontal part. A plurality of leg members are rotatably connected to each other by intersecting the horizontal abutment member, and each of the plurality of leg members is adjusted to the shape of the pedestal to adjust the intersecting angle and the horizontal contact with the horizontal part. By adjusting the amount of fitting with the members and fixing each horizontal abutting member to the horizontal portion of the base, the same leg member can be commonly used for various types of bases with different base shapes.

[Conventional technology]

A stand with legs, such as a desk, table, or chair, generally consists of a pedestal (top plate) and dedicated leg members that support it.

For example, as shown in FIG. 4, a pair of inverted U-shaped legs 2, 2 that match the shape and size of the pedestal 1
Leg assemblies 4 are fixed and held in parallel by reinforcing rods 3, 3 of predetermined dimensions, and are secured by mounting fittings 5.

Also, as seen in Utility Model Publication No. 40-10042, for example, a pair of inverted U-shaped stands as shown in Fig.
The reinforcing rods 3, 3 connecting the letter-shaped legs 2, 2 are configured to be expandable and retractable by hollow tubes and tube rods that fit together, and the length thereof is the length of the pedestal (dining table board). There are also some that can be adjusted to suit your needs.

Alternatively, as seen in, for example, Japanese Utility Model Application Publication No. 54-87101, as shown in FIG.
The two inverted U-shaped legs 11 and 12 consisting of b are crossed at the center, and screws 1 are attached to the pedestal (top plate) 10.
There is also a table, etc., which is attached to the pedestal 10 by fitting the respective horizontal portions into the fixing members 15.

[Problem that the invention attempts to solve]

However, in the conventional pedestal as shown in FIG. It could not be used on a pedestal due to its size or shape.

Furthermore, if the length of the reinforcing rod 3 is made adjustable, it can be used for pedestals that differ only in length, but cannot be used for pedestals that differ in width.

Furthermore, in the conventional stand as shown in Fig. 5,
By changing the intersection angle of the two inverted U-shaped legs 11, 11,
It has not been considered to use it for pedestals of different shapes, but even if it were done, it could be used commonly for pedestals with the same diagonal length and different length-to-width ratios. It cannot be used commonly for large and small pedestals with different diagonal lengths.

Therefore, in any case, with the conventional structure,
There is a lack of variation in combinations of pedestals and legs, and if you try to increase the number of variations, there is a problem that not only will the number of types of leg parts increase, resulting in higher costs, but also the risk of holding up a large amount of inventory in the manufacturing and sales channels. Ta.

This idea was made in view of the above points, and allows the same leg member to be commonly used for a variety of pedestals with different sizes and shapes, allowing for variations in the pedestal without increasing the types of leg members. The aim is to increase it significantly.

[Means for solving problems]

In order to achieve the above object, the table with legs according to this invention is constructed according to the following (a), (b), and (c).

(a) a pedestal; (b) a horizontal abutting member; and a set of inverted L-shaped members comprising a horizontal part and a vertical part, the horizontal part of which is slidably fitted to an end of the horizontal abutting member; (c) a fixing means for fixing each horizontal abutting member of the plurality of leg members to the horizontal portion of the pedestal; [Function] The table having legs according to this invention has the above-mentioned structure, and the intersection angle of each horizontal abutment member of the plurality of leg members and the horizontal part of each horizontal abutment member and each inverted L-shaped member are determined. By adjusting the amount of fitting, a common leg member can be used for various types of tables with different sizes and shapes, so the variations of the table can be greatly increased without increasing the types of leg members. I can do it.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

FIG. 1 is an exploded perspective view showing a first embodiment of this invention, which is applied to a chair for an electronic keyboard musical instrument such as an electronic organ.

The pedestal 30 in this embodiment has a frame portion 3 on the bottom surface.
0a, and inverted U-shaped legs 3, which are leg members of a leg assembly 34 to be described later, are provided at each of its four corners.
A U-groove-shaped leg fitting portion 30b into which the legs 3 and 33 are fitted is formed.

On the other hand, the leg assembly 34 includes a pair of inverted U-shaped legs 31 and 32, and their respective horizontal contact members 31a and 3.
Wood screws 33 that intersect and rotatably connect 2a.
It is composed of:

The inverted U-shaped leg 33 consists of one horizontal abutment member 3
1, and a set (two) of inverted L-shaped members 32, 32, each comprising a horizontal part 32a and a vertical part 32b, which are slidably fitted to both ends of the horizontal part 32, and the horizontal abutting member 31 The horizontal portions 32a of the pair of inverted L-shaped members 32 collectively form a horizontal abutting portion that can be expanded and contracted.

Both the horizontal abutting member 31 and the inverted L-shaped member 32 of this inverted U-shaped leg 33 are made of pipe, and each of the horizontal abutting members 31, 32 of the pair of inverted U-shaped legs 33,
31, the mutually contacting sides are pressed into a flat shape so that the cross-sections become semicircular as shown in Fig. 2, and a common screw hole 31a is drilled in the center. It has been done.

According to this embodiment, before assembly, each horizontal contact member 31 of a pair of inverted U-shaped legs 33, 33 and horizontal portion 32a of inverted L-shaped member 32 are deeply fitted, and the overall Shrink the horizontal contact part, and first
The leg 33 is connected to its pair of inverted L-shaped members 32, 32.
While adjusting the fitting length of the horizontal part 32a to the horizontal abutting member 31, fit it into the pair of leg fitting parts 30b, 30b located diagonally on the pedestal 30, and then the other inverted U-shaped leg 33. Similarly, a set of inverted L-shaped members 3
2 and 32 are fitted into the other pair of diagonal leg fitting parts 30b and 30b of the base 30.

In this state, the pedestal 30 and the two inverted U-shaped legs 33,
