Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spring structure provided with an auxiliary spring for reinforcing the periphery.

Conventionally, the periphery of the pine tress has been made hard to increase the effective usable area of the pine tress surface or to prevent the pine tress from losing its shape.

As a means for stiffening the periphery of the pinerest, an auxiliary spring is fitted between the upper and lower ends of a row of springs located at the periphery of a spring structure constituting the pinerest.

However, by inserting an auxiliary spring into the spring row,
When used in a pinerest, the auxiliary spring hits the helical wire connecting the spring rows, the frame line, or the spring, causing an unpleasant metallic sound that disturbs a good night's sleep.

In addition, in order to fit the auxiliary springs into the spring array without producing unpleasant noises, each auxiliary spring must be surrounded by a protective cloth, which is time-consuming and increases manufacturing costs. there were.

The present invention was developed based on the above circumstances, and its purpose is to harden the periphery of the spring structure through simple work without increasing manufacturing costs, and to stiffen the periphery of the auxiliary spring and the spring structure. To provide a spring structure which prevents unpleasant noise from being generated due to contact with a spring frame line located therein.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is a spring structure.

This spring structure 1 consists of long springs AI, A2, etc., each of which has continuous coil parts 10a, 10b, etc. formed from one wire, which are arranged side by side. are connected in a rectangular plate shape by a helical wire C...
At the upper and lower periphery, there is a frame line, D is clipped 4...
Spring A1 located on the periphery at...
It is connected to.

Then, clip the appropriate places on each of the above frame lines and D.
The auxiliary spring B is secured at one end, and the protective cloth 6, 6, such as a non-woven fabric, which is free at the other end, is sandwiched between the springs located around the periphery.
・is inserted between the upper and lower ends of the spring row located in the above-mentioned periphery, and the auxiliary spring B is fixed to the frame line with the clip 4 to D. There is.

To explain the structure of each of the springs A1..., the spring A1 is a connecting rod that connects the coil parts lea, 10b and the upper and lower ends of the adjacent coil parts 10a, 10b... 11a, 11b...
are continuously formed.

That is, the wire is wound in a downward direction to form the first coil portion 10a.

A lower connecting rod 11a having one end connected to the trailing end of the first coil portion 10a is led out in a substantially U-shape.

A wire is raised up from the other end of the lower connecting rod 11a and wound to form a second coil portion 10b in which a portion of the coil portion is engaged with the first coil portion 10a.

From the rising terminal end of the second coil section 10b, a wire is wound downwardly from the other end of the upper connecting rod 11b, one end of which is continuous with this terminal end, and a part of the coil section is wound around the second coil section.
The third coil portion 10C engaged with the coil portion 10b of
form.

In this way, by sequentially forming the coil parts 10a, 10b... and the upper and lower connecting rods 11a, llb..., these coil parts 10a...
A connecting rod 11a that connects the upper and lower ends of...

11b...A spring A in which 11b and 11b are continuous in a straight line.
1 is formed.

The springs AI, A2... are arranged in parallel, and the adjacent ends of the connecting rod located on the upper side and the connecting rod located at the lower end of each spring AI, A2... are helical. They are connected by line C...

Also, spring B... is spring A1, A2...
. . . Similarly, the coil portions 20 a to 20 b . . .
Each adjacent coil part 20a, 20b...
Connecting rods 21a and 21b that connect the upper and lower ends of...
. . . are continuously formed with one wire.

Further, as shown in FIG. 2, in this embodiment, the auxiliary spring B is auxiliary so that each terminal end of each coil portion 20a is positioned approximately at the center of the helical line C. A spring B is provided.

According to the spring structure having the above structure, the peripheral portion of the spring structure can also be made hard.

Also, when a load is applied to this spring structure, each spring A1
When the auxiliary spring B .
The coil portions located at both the upper and lower ends of 0b... are elastically deformed and collide with the helical wire C..., etc.

However, the auxiliary spring B and the helical wire C.
Since protective cloths 6, 6 such as non-woven fabrics are interposed between the auxiliary spring B and the helical wire C...
There is no direct contact between the auxiliary spring B and the helical wire C, and the protective cloth 6.6 can prevent the generation of unpleasant metallic sounds caused by direct contact between the auxiliary spring B and the helical wire C.

This unpleasant noise can be prevented by simply clipping one end of the protective cloths 6, 6 to the frame line D provided around the spring structure, which saves time and effort. Therefore, there is no increase in manufacturing costs.

Furthermore, since the connecting rod and the coil part of the auxiliary spring B are continuously formed by a single wire, it is only necessary to clip them to the frame line D at appropriate points, which saves time and effort.

As described above, since the present invention has the above-described configuration, it is possible to harden the peripheral portion of the spring structure without generating unpleasant noise, without requiring much effort, and without causing an increase in manufacturing costs.
