a and an annular lower base 4b facing the upper base 3.

Reference numeral 5 denotes a fan-shaped notch extending 90 degrees from the center of the plane of the head 4, and the notch has vertical side walls sandwiching the center of the notch to form a drawing wall 5a, and a bottom portion. is formed on the catch seat 6 having a horizontal surface.

7 is a screw that connects and holds the main body 1 and the head 4 fitted to the main body 1;
It is planted between the lower part 4b of the.

Incidentally, the manner in which the script body 1 and its head 4 are connected is not limited to this embodiment, and may take any other arbitrary structure.

Reference numeral 7a denotes a support piece provided on the same plane as the planar seat 6 and radially outward of the notch 5, and 7b is a bolt hole provided through the support piece.

The leg 1A according to the present invention configured as described above is used as a leg of a table or a chair in a planar form as shown in FIG.

That is, the four legs 1A are, in principle, erected with their notches 5 aligned with the four corners of the virtual rectangular body, and have the same planar shape as the virtual rectangular body and a slightly larger maximum depth than the maximum depth of the notch 5. A rectangular plate 8 as a top plate or a seat plate formed with a thickness is supported at its four corners 8a to 8d by the surface supports 6 of the cutout portions 5 of each leg, so that a table or a chair with legs, etc. It is composed of furniture.

Incidentally, the rectangular plate 8 is fixed to each leg 1A by implanting bolts or the like through the bolt holes 7b of the support piece 7a on the back surface thereof.

In this way, when four legs 1A of the present invention are used, each leg 1A can be made to function as a furniture leg by placing each leg 1A on the four corners 8a to 8d of the rectangular plate 8. No matter how the size of the rectangular plate 8 is changed, the difference in size of the rectangular plate 8 can be accommodated by simply changing the standing position of each RIA according to the size of the rectangular plate 8. be able to.

In addition, when the legs 1A are used as the legs of a table, the legs 1A may be formed to have a total height corresponding to the height of the top plate of the table.

Furthermore, since the above-mentioned leg 1A of the present invention is provided with a notch 5 with a plane angle of 90 degrees, the top plate or seat plate mounted on the leg 1A is not limited to a simple plane-fitting shape; Any shape may be used as long as it has an irregular polygonal shape in plan view having at least three corner portions formed therein.

FIG. 5 shows an example in which a polygonal plate 81 having three corners 81a to 81c formed at 90 degrees in plane is used as a seat plate or a top plate.

The leg 1A of the above embodiment has a structure in which the script body 1 and the leg head 4 are formed separately and then integrated later, but the main body 1 and the leg head 4 are formed integrally from the beginning. It may be something you have done.

FIG. 6 is a side sectional view showing an example of the body 1 and the head 4 having an integral structure from the beginning. In this case, the annular seat 2, the upper base 3, and the connecting The bolt 7 can be omitted.

In FIG. 6, the same reference numerals as in FIG. 1 indicate the same parts.

Since the leg of the present invention has the above-described structure, the cast region is suitable for molding with synthetic resin, etc., and can be manufactured relatively easily, and is also suitable for mass production. suitable.

Moreover, when a table or chair is constructed using the legs of the present invention, each leg is positioned so as to protrude from the four corners of the top plate or seat plate, and the legs themselves have a structure that allows them to stand on their own, making the installation extremely stable. Furniture with high quality can be obtained, and the parts protruding from the top and seat boards, especially the heads of the legs, are formed into a rounded dome shape, making the furniture excellent in terms of safety. For example, it has many advantages, such as being able to form benches and tables for outdoor installation.

Next, in the legs of the present invention, the cutout angles of the cutout portions 5 are formed at 180 degrees (some have continuous 90 degree cutouts 5 and others have back to back) and 270 degrees, and connections that share the legs are formed. Since furniture can be constructed, this connection structure will be explained with reference to FIGS. 7 to 9.

When connecting tables or chairs, as shown in Figure 7 or Figure 9, adjacent ones are connected in such a way that their top plates or seat plates share part of the legs, so they become the top plate or seat plate. In the leg supporting two or more rectangular plates 8, the notch angle of the notch 5 is different from that of the leg 1A of the above embodiment.

That is, when supporting the corners of two rectangular plates 8 with one leg, the leg 1B has the notch 5 cut out at 180 degrees, or 502 notches at 90 degrees are symmetrically arranged. Formed leg 1C
In addition, when supporting three rectangular plates 8 with one leg, the leg 1D with the notch 5 formed at a notch angle of 270 degrees is used.
Use.

As shown in FIG. 9, the legs supporting the portion where the corners are gathered radially include a leg 1E having a flat leg head 4;
In other words, the leg of the present invention, which uses the notch 5 formed over 360 degrees, has an extremely simple structure, so the angle of the notch is changed in 90 degree increments. 1
41A to 1E and those with different heights, a top plate or a seat plate with corners formed at 90 degrees can be inserted into the notches 5 of the legs.
By simply mounting and fixing the legs on a rack, it is possible to obtain tables and chairs that are individually independent, or tables and chairs that are connected in various ways. If the structure is configured as described below, different types of furniture such as tables and chairs can be connected.

In such a case, the outer shape of the leg 1F is a cylinder or a cone shape close to a prism, and the head part of the script body is formed to have a thickness large enough to be able to stand on its own. The head part is cut out radially in 90 degree increments from the center of the plane, and the wall surface on the back side of the cutout is cut out from the center of the plane at the middle of the height direction of the script body. A 90-degree flat surface AAA is cut 180 degrees to form two notches having a continuous vertical wall and a flat surface, sandwiching the centers of the two notches, and each of the above-mentioned walls and the flat surface. A top plate, a seat board, etc., whose corners are 90 degrees flat and whose thickness is approximately equal to the maximum height of each of the above-mentioned walls, is placed on both cut-out portions including the surface, and the corners are placed on both cut-out portions. The device is characterized in that it is mounted and fixed in close contact with a vertical wall and a flat surface.

Next, an example of the leg 1F having the above structure and connected furniture using this leg will be explained with reference to FIG. 10.

That is, the upper main body 10A of the leg has the same configuration as the leg 1A of the above embodiment, but the upper main body 10A has a portion located below the upper main body 10A and approximately in the middle in the overall height direction.
A lower body having a notch 51 formed in the opposite direction to the notch 50 of the lower body.

By connecting and forming 11A, an example of leg 1F is constructed.

In addition, 40 is a leg head, and 70a. 71a is the cutout portion 50, 51
It is a support piece formed continuously on the bottom of the.

FIG. 11 shows the state seen from the plane of the side where the table and chair are combined using the leg 1F. In order to construct the combined furniture using this leg 1F, first, The four legs 1F are oriented on the ground or the like so that the notches 50 of the upper body 10A are located at the four corners of the virtual rectangular body.

Here, since the notches 51 of the lower body 11A of each leg 1F are positioned facing the outside of the virtual rectangular body, two notches 5L51 facing the same direction form a set of corners. Assuming a virtual rectangular body, the notches 5 are adapted to the other two sets of corners of this rectangular body, and the legs 1A are made into 4 pieces.
When fully erected, the legs for this combined furniture will be formed, and each of the eight previously installed legs will have four notches 5.
0 is a rectangular plate 80 that will be the top of the table, with its four corners 80
A to 80d are fixedly placed on the racks, and rectangular bodies 82 and 82, which will become the seat plates of the chairs, are placed in the notches 5°5.
If a to 82d are fixed on a rack and installed, it can be configured as combined furniture consisting of a table and a chair that share the legs 1F.

Even in the combined furniture of the above embodiment, even if the size of the rectangular bodies 80 and 82 that become the top plate and the seat plate changes, the standing position of each leg can be simply changed in accordance with the positions of their four corners. In addition, when connecting these combined furniture pieces, each leg IA may be adjusted according to the connection direction.

If you use the one with the plane cutout angles of the cutouts 5, 50, and 51 on the 1st floor set, the difference in the size of the top plate and seat plate, or
It can correspond to the connection direction.

Further, in the above embodiment, the leg 1F has a structure in which the upper main body 10A and the lower main body 11A are constructed separately and the two are connected later.

The leg 11A may be integrally molded from the beginning as in the case of the leg 1A described above.

The present invention is as described above, and the legs of furniture are formed in the shape of a cone having a thickness large enough to be able to stand on its own, and the head is formed in the shape of a dome-like hemispherical cap. 11 in that plane. By making radial notches in units of 90 degrees from %, notches with vertical wall-like walls and flat receiving seats sandwiching the center of the notch have notch angles of 90 degrees, 180 degrees, and 270 degrees, respectively. By supporting the four corners of a rectangular plate having a thickness corresponding to the maximum depth of the notch in close contact with the picture wall and the seat of the notch, a notch with a notch angle of 90 degrees can be formed. Legs with a cutout angle can be used to extremely easily construct independent tables, benches, and other furniture, and legs with a cutout angle of 180 degrees or 270 degrees can be used with separately manufactured connectors, etc. not required, and
There is an advantage that the legs of adjacent parts can be shared, making it possible to easily and rationally configure the connected furniture of the table or bench,
Furthermore, the legs of the present invention incorporated in the above-mentioned table, etc., are sufficiently thick to stand on their own, and are positioned so as to overhang from the corner of the top plate, etc., which is supported by areas other than those in which the notch is formed. Even if the connection between the top plate, etc. and the legs is simple, it is not only highly stable in terms of connection and installation, but also the leg heads protruding from the corners of the top plate, etc. are formed in a dome shape. It has advantages not seen in conventionally known furniture legs, such as no sharp parts and high safety.

In particular, the above-mentioned high stability and safety bring about remarkable effects when the legs of the present invention are used for outdoor benches and tables.
