Abstract

PURPOSE:To provide a mattress giving a feeling of flatness, which has springs therein and has vibrators put in a container held by the springs to reduce projections formed by the vibrators. CONSTITUTION:This mattress is formed into a flat plate by arranging many springs therein and then connecting the springs lengthwise and crosswise with connective rings. In the mattress, vibrators 12 and laid under some parts of the mattress where the fatigable part of a human body, such as shoulders, a waist or calves of a person of average height will be laid. Each vibrator 12 adheres to the bottom of a chamber 13a in a thick sheet 13 as a container with an adhesive tape 14. A metal plate 17 is screwed on the surface of the vibrator 12 through a fabric sheet 16. Both ends of a band 18 made of a polypropylene intervening between the metal plate 17 and the fabric sheet 16 are held by springs 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress that generates vibration and contributes to recovery of body fatigue.

[0002]

2. Description of the Related Art As a conventional technique of this kind, Japanese Patent Laid-Open No.
The technique disclosed in JP-A-1-87560 is known. In this, a spring is connected in a flat plate shape in a mattress softly placed on a bed base, and a vibration generator is arranged on the spring via a hard fiber pad. Further, an elastic material such as urethane foam and an exterior body cover the vibration generator. Further, the above-described vibration generator is a DC motor, an eccentric weight attached to the shaft of the motor, a box body for holding the motor, and a flange portion of the box body fixed to the mattress and continuously arranged around the mattress. The eccentric weight is rotated by rotating the motor to vibrate the motor, the box body, and the diaphragm.

[0003]

In the above-mentioned conventional technique, since the vibration generator including a motor and the like is arranged on the spring, the box portion of the vibration generator is projected during use. It felt like something was wrong.

A technical object of the present invention is to provide a mattress that does not feel uncomfortable due to a vibration generator.

[0005]

Means for Solving the Problems In order to solve the above-mentioned technical problems, the technical means taken by the present invention is a mattress having a spring inside, a vibration generating device arranged in the mattress, and a spring. And a storage member that forms a storage space that is held by the storage device and that can store the vibration generator.

[0006]

The operation of the invention of claim 1 will be described. Since the vibration generator is stored and fixed in the storage space of the storage member, the protrusion of the vibration generator can be reduced or eliminated by forming the storage space below the upper surface of the spring. A mattress that does not feel a sense of discomfort is provided.

The operation of the invention of claim 2 will be described. Since the vibration generator is held by the spring by the holding member, it is possible to prevent the vibration generator from being displaced when the mattress is placed horizontally, vertically, and turned upside down.

[0008]

Embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, springs 11 are arranged in the mattress 10 and are connected to each other by a connecting ring 11a (FIG. 4) to form a flat plate.

Further, in the mattress 10, vibration generating devices 12 are arranged at the shoulders, hips and calves of a person having an average height (set to 171 cm in this embodiment) (portions where fatigue is likely to accumulate). .

As shown in FIGS. 3 and 4, the vibration generator 12 is a storage space 1 for a thick sheet 13 which is a storage member.
3a is adhered to the bottom of the thick sheet 13 with a velcro tape 14, and a hard fiber pad 15 is sandwiched between the thick sheet 13 and the flange portion 12a of the vibration generator 12, and a hole is formed in the thick sheet 13 due to abrasion. Even when it is opened, the spring 11 and the vibration generator 12 are in contact with each other so that no abnormal noise is generated. Also, the vibration generator 12
A metal plate 17 is screwed to the upper surface of the metal plate 17 via a cloth sheet 16, and the metal plate 17 and the cloth sheet 16 are further connected.
A polypropylene band 18 is interposed between and, and both ends of the band 18 are held by the springs 11. A connector 12b connected to a control circuit (not shown) extends from the vibration generator 12. On the other hand, the upper surface of the metal plate 17 is covered with an exterior 20 via an elastic body 19 such as urethane foam.

Next, the operation of this embodiment will be described. Since the vibration generator 12 is housed in the storage space 13a of the thick sheet 13 serving as a storage member, and the storage space 12a is formed below the upper surface of the spring 11, the protrusion of the vibration generator 12 is reduced. A mattress that can be made comfortable is provided. In addition, band 18
Since the vibration generator 12 is held by the spring 11, the vibration generator 12 can be prevented from being displaced when the mattress 10 is placed horizontally, vertically, and turned upside down.

Next, a modified embodiment according to the present invention will be described with reference to FIGS. In both figures, only the differences from the above embodiment will be described. On the metal plate 17,
A sheet 21 made of the same material as the thick sheet 13 is provided and fixed to the thick sheet 13 with pins 21a.
With this, as in the above-described embodiment, the mattress 10
It is possible to prevent the vibration generator 12 from being displaced when it is placed horizontally, vertically, or turned upside down.

[0014]

The effect of the invention of claim 1 will be described. Since the vibration generator is stored and fixed in the storage space of the storage member, the protrusion of the vibration generator can be reduced or eliminated by forming the storage space below the upper surface of the spring. It is possible to provide a mattress that does not feel a sense of discomfort and does not make you feel a protrusion.

The effect of the invention of claim 2 will be described. Since the vibration generator is held by the spring by the holding member, it is possible to prevent the vibration generator from being displaced when the mattress is placed horizontally, vertically, and turned upside down.
