Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a three-sided structure, particularly to a three-sided structure in which a cylindrical base leg is separable for folding. In this specification, the word "sampo" in relation to the present invention is used in a broad sense including the description of the claims section of the utility model registration, and includes four directions and offerings.

Sankata is a type of chuju, that is, a cylindrical (usually square-cut cylindrical) pedestal attached to the bottom of the fold, but modern Sankata has a cylindrical base attached to the bottom of the fold to make it convenient for storage. Many are seen with detachable legs.

Conventional technology and its problems However, even with such a separate type, it was not always convenient to store the conventional three sides. In other words, in the past, for three sides of the same size, the cylindrical base legs had the same body diameter, so two cylindrical base legs could not be fitted together, and multiple sets of three sides could not be fitted together. When storing and transporting them, they were forced to take up a considerable amount of space.

The purpose of the present invention is to provide a three-sided system with separable cylindrical base legs for folding and folding, which requires approximately half the space occupied during storage and transportation for multiple sets of the same type of folding. be.

Furthermore, in the present invention, even when assembling the cylindrical pedestal leg to the folding table using a tight fit without play, the assembly can be easily performed by appropriately designing the contact surface of the tight fit. It aims to provide three sides.

Means for Solving the Problems The object of the present invention is to combine a folding pedestal and one of two mating cylindrical pedestals, and the pedestal and cylindrical pedestal can be separated. A recessed portion is formed at a portion of the lower surface of the folding bed corresponding to the upper end of the cylindrical pedestal, and a convex portion that fits into the recessed portion is formed at the upper end of the cylindrical pedestal. The recess is achieved by three sides having a width that allows the two cylindrical base legs to fit into each other and adjacent convex parts on the inside and outside of the upper ends of the base legs to fit into the convex parts.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a folding base, 2 and 3 are cylindrical base legs, and the cylindrical base legs 2 and 3 have similar cross sections that fit together, and which of these cylindrical base legs 2 and 3 The combination of the katakashiki 1 and the keshiki 1 constitutes three sides.

recessed portions 4, 5, 6, 7 are provided on the lower surface of the folding bed 1 at locations corresponding to the upper ends of the cylindrical base legs 2, 3;
The recessed portions 4, 5, 6, 7 are located at the upper ends of the cylindrical base legs 2, 3.
Convex portions 8, 9, 10, 11, 12, 1 that fit into
3, 14, and 15 are formed. The recessed portions 4, 5,
The width a of 6 and 7 is determined by the convex portions 8, 12, 9, which are adjacent to each other on the inside and outside (thickness direction) of the upper ends of the two cylindrical base legs 2 and 3 when they are fitted together. 13,1
The width is such that 0, 14, 11, and 15 fit.

16 shows the molded shape of the cylindrical base legs 2 and 3.

The convex parts 8, 9, 10, 11 on the upper end of the cylindrical base leg 2 or the convex parts 12, 13, 14, 15 on the upper end of the cylindrical base leg 3 are placed in the concave parts 4, 5, 6, 7 on the lower surface of the folding bed 1. Fit,
Thus, the folding bed 1 and the cylindrical base leg 2 or 3 are assembled so that the three sides can be separated. In this case, if one of the two mating cylindrical base legs 2, 3 that corresponds to the external fit is applied, the convex portions 8, 9, 1 at the upper end of the base leg 2
0 and 11 fit into the outer half of the recesses 4, 5, 6, and 7 on the lower surface of the folding bed 1, and when a cylindrical base leg corresponding to internal fitting is selected, the convex parts 12 and 1 on the upper end of the base leg 3 are selected.
3, 14, and 15 fit into the inner half portions of the recesses 4, 5, 6, and 7. That is, the recessed portions 4, 5, 6,
Since the width a of 7 is the specific width shown above, the convex parts 8, 9, 10, 11 of the cylindrical base leg 2 and the convex parts 12, 13, 14, 15 of the cylindrical base leg 3 are Not only does it contribute to the fitting of both, but also the concave portions 4, 5,
The inner or outer half of 6 and 7 will be empty.

If necessary, the concave portions 4, 5, 6, 7 and the convex portion 8,
9, 10, 11 or 12, 13, 14, 15 by fitting the cylindrical table leg 2 or 3 to the folding bed 1
The assembly may be such that the fitting is a tight fit and there is no looseness. Even when such an assembly method of the folding pad 1 and the cylindrical base leg 2 or 3 is adopted by such a tight fit, the recessed portions 4, 4, 6, and 7 are places where the inner or outer half is open as described above. Therefore, the concave portions 4, 5, 6, and 7 are formed, and the convex portions 8,
For 9, 10, 11, the outer surface, convex portion 1
2, 13, 14, and 15, by appropriately designing the abutment surfaces of the tight fitting so that the recesses 4, 5, and 6 are in contact with only the inner surfaces thereof. , 7 with convex portions 8, 9, 10, 1
1 or the convex parts 12, 13, 14, 15 can be easily fitted, and the folding bed 1 and the cylindrical table leg 2 or 3 can be easily assembled. The simplicity of this assembly is due to the fact that the outer wall surface 17 and the inner wall surface 1 of the recessed portions 4, 5, 6, 7
8 Chamfer the lower corner diagonally or in a rounded shape 19
If you do that, it will get even better. The outer wall surface 17 and the inner wall surface 18 are spaced apart from each other by the recessed portion 4,
It may be a tapered type that becomes slightly narrower toward the back (upper side) of 5, 6, and 7, or it may be a parallel type that is not such a tapered type.

When storing or transporting the cylindrical base legs 2 and 3, as shown in FIG. In terms of the size of the folding floor 1, for multiple sets of three sides of the same type, the space occupied during storage and transportation is approximately half that of the conventional three sides.

Effects of the invention As described above, according to the present invention, the cylindrical base leg is separable from the folding table, and the space occupied during storage and transportation is approximately half that of the conventional one for multiple sets of the same type of folding plate in terms of dimensions. In addition, even if the cylindrical base leg is assembled with a tight fit without play, the assembly can be easily achieved by appropriately designing the contact surface of the tight fit. It can be done simply.
