Description

[Detailed description of the invention] The present invention relates to a pine tress, which is used in beds, etc., and has a large number of coil springs arranged in a row. The purpose is to eliminate the

Conventionally, pine tresses with coil springs interposed between both sides as elastic bodies are usually constructed with identical coil springs arranged evenly in the vertical and horizontal directions, so when a load is applied to the ends of the pine tress, However, the number of springs supporting the load is small, and the amount of compression of the coil spring becomes large, causing the edge to slump.

For this reason, as a technique to harden the edges of the pinerest, the elasticity of the coil springs at the periphery is made stronger than the coil springs at other parts. It was desired to obtain sufficient hardness because rubbing would make the feeling of use worse, but the present invention has been developed by inserting other coil springs between the coil springs of the side line row to increase the elastic strength of the edges. The spring is housed in a cylindrical body, such as a non-woven fabric, to eliminate the contact noise between the springs, and at the same time, the upper and lower ends of the cylindrical body are wound around a part of the provided spring assembly and installed. It is something to do.

Hereinafter, the present invention will be explained in more detail with reference to the drawings showing an embodiment of the present invention. Fig. 1 is a partially cutaway plan view of a pinerest, and Fig. 2 is a front view thereof.

The pine tress has coil springs 1 and 1' arranged side by side adjacent to each other in the horizontal direction and spaced apart from each other by a certain distance in the vertical direction, and stretched between the respective longitudinal frames of border wires 2 and 2 forming the outer edges of both the upper and lower surfaces. Racing helical line 3, 3...
..., and the border wire 2 and the coil springs 1, 1' are loosely connected by a path load clip 4.

5 is a connecting pipe connecting the ends of the border wire 2.

As shown in FIG. 1, a coil spring body 6 is inserted between each coil spring 1' at the side edge of the group of coil springs arranged in parallel, and the coil spring body 6 is inserted as shown in FIG. The coil spring 7 is housed in a cylindrical body 8 made of breathable non-woven fabric such as polypropylene, and the side frame part A1 of the border wire 2 shown in the first figure, the part B of the racing helical wire 3 or the coil The cylindrical body 8 is attached to the end C# of the spring 1' as shown in
The end portion 8a of is wrapped around and fixed to a stopper 9.

Although the space between the two coil springs i' and i' is narrower than the outer diameter of the inserted coil spring T, by positioning the springs so that the pitches of the springs engage with each other, it is possible to install the springs sufficiently.

A sheet member 10 made of polyurethane or the like is placed on the upper and lower surfaces of the spring assembly having the above structure, and a surface member 11 made of quilted fabric or the like is completely covered to form a pinerest.

The above-mentioned structure (this pine brace has the elasticity of the coil spring 7 supplemented in the side line part) increases the total amount of surface pressure and eliminates depression of the edge of the pine brace, and furthermore, the coil spring body 6 Since the cylindrical body 8 is placed over the coil spring 7, even if the coil spring 7 is engaged with the adjacent coil spring 1', the cylindrical body 8 is inserted between the two members and there is no contact. In addition to preventing the generation of noise, etc., it can be easily installed by wrapping the end 8a of the cylindrical body 8 around other members.

It goes without saying that the cylindrical body 8 can be made of not only non-woven fabric but also woven fabric etc. to achieve the same effect.

As explained above, this invention can increase the elasticity of the side edges of the pine brace and prevent it from falling, and by simply adding one spring between the edge coil springs of the conventional spring assembly. It has extremely high practical effects, such as sufficient effects.
