Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cushion body used for pinerests and the like.

(Prior art) Cushion bodies generally used for pinerests, etc., are formed by connecting a large number of springs in a flat plate shape with helical wires to form a spring unit. The spring unit is constructed by polymerizing a protective material such as sisal or an elastic material such as urethane foam, covering the spring unit with a cloth, etc., and securing the spring unit with tags around the periphery of the spring unit. The pine tress is then covered with an exterior material sewn into a bag shape.

By the way, when the above cushioning body is used for a pine tress, the protective layer such as sisal and the elastic body such as urethane foam are not integrated with the spring unit, so the protective layer rubs against the spring unit during use. In addition, there are problems in that the protective layer and the elastic body move, causing damage to the protective layer and the elastic body, and that unpleasant noises are generated, making it uncomfortable to sleep.

Furthermore, when a human body falls down on a pinerest using the cushion body, the springs are compressed and deformed to elastically support the human body, but the amount of deformation of each spring differs depending on the load they receive. In other words, since the human body is heaviest at the waist, the amount of deformation of the spring that supports this waist is greater than for other parts.As a result, the waist of the human body is supported in a state where it is largely sunk within the spring unit. The sleeping position of the human body is such that the back muscles are bent, which makes sleeping uncomfortable.In order to solve this problem, it is possible to increase the elasticity of the springs. Since the hardness is transmitted to the human body, there is a problem in that the soft feel, which is important for performance, is lost.

(Problems to be Solved by the Invention) The present invention has been made based on the above circumstances, and its object is to integrally connect a spring unit, a protective sheet, and an elastic body, and furthermore, to By providing a reinforcing body made of an elastic material approximately in the center, it prevents unpleasant noises during use, prevents early loss of the elastic body, and improves the cushioning properties of the spring unit and the cushioning properties of the elastic body and the reinforcing body. For pine tresses, etc., which exhibit an integrally coordinated spring action and can be made hard without compromising good cushioning properties and a soft feel.
The object of the present invention is to provide a cushion body that can be worn.

(Structure of the Invention) In order to solve the above problems, the present invention comprises a spring unit formed by connecting a large number of springs in a flat plate shape, and an elastic phase provided at least approximately in the center of the spring unit. A reinforcing body, a protective sheet laid on the upper and lower surfaces of the spring unit, and a foamed elastic material (e) is foamed on the protective sheet and integrally combined with the protective sheet and the spring unit.・Equipped with an elastic body provided at a predetermined thickness on top.

And the above spring unit!・It exhibits a spring action that works together with the elastic body, and the reinforcement body makes it hard with a soft feel.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, 1 indicates a large number of springs 2... and a helical wire 3...
This is a spring unit formed by connecting the springs in a flat plate shape and connecting frame lines 4, 4 around the upper and lower surfaces thereof. A mesh 5aK made of a material such as a synthetic resin is formed on the lower surface of the spring unit 1 at an angle of 1°, and a protective sheet 5 is laid thereon. A large number of through holes 6 are formed in a predetermined thickness, and an elastic body 7 is provided which covers the protective sheet 5 and the end of the spring 2 of the spring unit 1 and is integrally coupled with the protective sheet 5 .

At approximately the center in the longitudinal direction of the spring unit 1, a space 8 formed between adjacent springs 2 of the spring unit 1 extends in the width direction of the spring unit 1. A plurality of reinforcing bodies 9 made of an elastic material such as urethane foam formed into a prismatic shape,
The upper and lower end surfaces thereof are integrally connected to the elastic body 7 to form a cushion body M.

By the way, the cushion body N1 is formed as shown in FIG. That is, a protective sheet 5 is laid on the upper and lower surfaces of the splinter unit 1, and several places around the protective sheet 5 are placed with one clip 10 on the frame line 4°4 of the spring unit 1.
...I'm stopping.

Then, a plurality of reinforcing bodies 9 are sandwiched between the upper and lower end surfaces of the springs 2 in the space 8 between the adjacent springs 2 in the longitudinal center of the spring unit 1. Let's set it up.

The top surface is open and a large number of pins 11 protrude upward.
... is provided, and in a frame-shaped mold 12, the pin 11 of the mold 12 is passed through the mesh 5a of the protective sheet 5, and the tip of the pin 11 is located in the middle of the spring 2. Then, the spring unit 1 is suspended by an appropriate method (not shown) while maintaining a predetermined distance from the inner surface 13 of the mold 12. Then, a predetermined amount of foamed elastic material such as urethane foam is injected into the mold 12 from the foaming machine 14 and foamed, and then the mold 12 is used as a template to form the elastic body 7. As shown in FIG. 3, this foamed elastic body 7 passes through the mesh 5a of the protective sheet 5, enters the spring unit 1, covers the end of the spring 2, and is integrated with the reinforcement body 9. Join. Therefore, the reinforcement body 9 is integrally connected to the elastic body 7 and the spring unit 1. In addition, the elastic body 7 has the mold 1
A large number of through holes 6 are formed by the bottles 11 provided in 2.

Then, the cushion body 11v1 having the above structure is covered with an exterior fabric (not shown), or stuffing such as cotton is laid on the upper and lower surfaces of the cushion body M to cover the exterior fabric,
Configure pine tress. According to the cushion body M having the above configuration, the spring unit 1 and the protective sheet 5
Since the elastic body 7 and the elastic body 7 are integrally connected, the protective sheet 5 and the spring unit 1 will not rub against each other during use, and no unpleasant noise will be generated.

Furthermore, since the elastic body 7 and the protective sheet 5 do not rub against each other, damage to both can be prevented. Furthermore, among the loads applied to the cushion body N1, the largest load on the lower back is caused by the elastic body 7 and the spring unit 1.
A large number of springs 2 constituting the spring unit 1 and a reinforcing body 9 provided over the entire length of the spring unit 1 in the width direction in the space 8 formed between adjacent springs cooperate integrally. It undergoes elastic deformation. That is, since the load is distributed among the elastic body 7, the springs 2, and the reinforcing bodies 9, the spring unit 1 is in a state where the amount of deformation is small relative to the load, that is, it becomes hard. therefore,
Even when the human body is soaked, the heavy lower back part does not sink into the spring unit 1, and the user can maintain a sleeping posture with a straight back, and the body becomes stiffer without losing its soft feel.
Get a good cushion body.

Furthermore, since the reinforcing body 9 is integrally connected to the elastic body 7 and the spring unit 1, it will not shift during use and can reliably receive the load. In addition, since the elastic body 7 is provided with a large number of through holes 6, it is possible to ventilate the inside of the spring unit 1, thereby preventing moisture from accumulating inside the spring unit 1. Therefore, it is extremely hygienic.

Note that the present invention is not limited to the above-mentioned example,
For example, as shown in FIG. 4, the reinforcing body 9 may be provided over the entire cushion body.

Further, in the above embodiment, the reinforcing body 9 is provided integrally with the elastic body 7, but after the elastic body 7 is foam-molded, the reinforcing body 9 is inserted from the side of the spring unit 1 into the spring unit l. It may also be provided so as to be inserted inside. Further, the hardness of the reinforcing body is not limited at all, and may be any hardness that does not impart stiffness to the human body.

Further, the maintenance μ sheet 5 does not necessarily require rigidity.

If the cushion body N1 has a certain degree of rigidity, the cushion body N1 will become even harder, and the effect will be even greater.

(Effects of the Invention) As described above, the present invention connects a large number of springs in a flat plate shape to form a spring unit, lays a protective sheet on the upper and lower surfaces of this spring unit, and places a protective sheet on the upper and lower surfaces of the spring unit. A foamed elastic material is foamed and integrally combined with the protective sheet and the spring unit, and an elastic body having a predetermined thickness is provided, and the elastic body is provided at least approximately in the longitudinal center of the spring unit and between adjacent springs. Since the reinforcing body made of an elastic material is provided in the space, the protective sheet and the spring unit do not rub against each other, so that no unpleasant noise is generated and the sleeping comfort is not made worse. Further, since the elastic body deforms integrally with the protective sheet and the spring unit, it does not rub against or move against the protective sheet or the elastic body, so that early damage can be prevented. In addition, since the elastic body, spring unit, and reinforcing body are elastically deformed as one unit, the lower back of the human body does not sink significantly, allowing a person to maintain a sleeping posture with a straight back, without sacrificing the soft feel. It can be made hard and has good cushioning properties.
