Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a pinerest device equipped with a vibration generator.

(Prior Art) Some pinerest devices have a built-in vibration generator and are designed to pine-surge a user lying on the pinerest device.

The means for vibrating the vibration generator includes dividing the electric signal from the music from the sound generator,
The middle and high frequency range of one of them is subjected to electro-acoustic conversion by a speaker, and only the low frequency range of approximately 150Hz or less from the other is extracted using a low-pass filter. This low-frequency electric signal is then amplified by an amplifier, and the amplified signal is used to vibrate the vibration generator. When the vibration generator is vibrated in this manner, the vibrations become so-called rhythmic vibrations corresponding to the music, so that the user can be given not only physical pleasure but also psychological pleasure.

(Problems to be Solved by the Invention) By the way, when applying vibration to the pinerest device using a vibration generator, it is desirable to be able to transmit the vibration to as wide an area as possible. However, simply providing a vibration generator in the above-mentioned mattress device does not allow a large transmission area for the vibrations. Therefore, a large number of vibration generators are required to vibrate a large area of the pinerest device, which not only increases costs, but also
The hardness of the numerous vibration generators has caused a significant loss of the soft feel of the pinerest device.

This invention was made based on the above circumstances, and its purpose is to provide a pine stress device that can transmit vibrations over a wide area using a single vibration generator. shall be.

(Means and effects for solving the problem) This invention consists of a spring unit formed by connecting a large number of springs in a pattern, an elastic material superposed on at least the upper surface of the upper and lower surfaces of the spring unit, and An exterior covering made of a polymer of elastic material and a spring unit, and a non-stretchable and flexible material stretched over the upper surface of the spring unit with both ends connected to a frame line connected to the periphery of the spring unit. and a vibration generator attached to the belt-shaped sheet with the axis of the rotating shaft substantially perpendicular to the longitudinal direction of the belt-shaped sheet. Then, the vibration of the vibration generator is transmitted through the belt-shaped sheet.

(Example) An example of this invention will be described below with reference to the drawings. 2 and 3 show a mattress device 1 as a cushion device. This pine stress device 1 connects a large number of coil springs 2 with helical wires 2a.
Spring units 3 connected in a matrix by
It is equipped with A frame line 4 is connected to the periphery of the upper and lower surfaces of the spring unit 3 over the entire circumference. Further, elastic materials 6 such as urethane foam are superposed on the upper and lower surfaces of the spring unit 3 through protective materials 5 such as sisal or pressed palm. This polymer is then covered with an exterior material 7.

A vibration generator 8 is provided approximately at the center of the upper surface of the spring unit 3 in the longitudinal direction. This vibration generator 8 has a vibration generator 9 as shown in FIG. This vibration generator 9 is the tsuba 11
A motor 13 is elastically held in a case 12 by packing 14. The motor 13 is a two-axis motor, and a weight 16 is eccentrically attached to each rotating shaft 15. Therefore, when the weight 16 is eccentrically rotated by the motor 13, the entire vibration generator 9 vibrates.

The vibration generator 9 is attached to the belt-shaped sheet 17. This belt-shaped sheet 17 is made of a flexible but non-stretchable material. As the belt-shaped sheet 17, for example, as shown in FIG. 4, a sheet of cloth 18 with rubber 19 coated on both sides is used. A notch 21 is formed along the width direction approximately at the center of the belt-shaped sheet 17 in the longitudinal direction. As shown in FIG. 1, the vibration generator 9 is dropped into the notch 21 with the axis of its rotating shaft 15 perpendicular to the longitudinal direction of the strip sheet 17, and is fixed to the strip sheet 17 by adhesive. It is held by a pressed presser cloth 22. and,
The vibration generating device 8 configured in this manner is configured so that when the user lies down on the mattress device 1, the belt-shaped sheet 17 runs along the width direction of the spring unit 3 at a position corresponding to the buttocks of the user. and its both ends are connected to the frame line 4.

In the pinerest device 1 having such a structure,
When the motor 13 of the vibration generator 8 is energized to operate the vibration generator 9, the vibration generator 9 is activated by the weight 1.
By eccentric rotation of 9, the X direction and Y direction shown in FIG.
It vibrates in both directions. That is, the vibration generator 9 vibrates in the vertical direction, which is the Y direction, and in the horizontal direction, which is the X direction along the width direction of the mattress device 1. When the vibration generator 9 vibrates in this way, the belt-shaped sheet 17 is interlocked with the vibration. Among the vibrations in the X direction and the Y direction, vibrations undulating in the Y direction are difficult to propagate to far positions, while vibrations in the X direction are transmitted effectively. In other words, although the belt-shaped sheet 17 is flexible, it is not stretchable, so the vibration in the X direction is transmitted to a distant position without being attenuated midway. Therefore, the vibration of the vibration generator 9 can be transmitted to the entire length of the mattress device in the width direction. Further, since both longitudinal ends of the band-shaped sheet 17 are connected to the frame line 4, its vibrations are transmitted to the frame line 4. Frame line 4
is made of hard steel wire, and has elasticity when connected to the spring unit 3. And this frame line 4
is connected to the periphery of the spring unit 3, so vibration in the X direction pulls the frame line 4 and causes it to vibrate. Therefore, vibrations are transmitted to the entire spring unit 3. That is, since the belt-shaped sheet 17 and the entire spring unit 3 to which this belt-shaped sheet 17 is connected can be vibrated by one vibration generator 9, the buttocks of the user lying on the mattress device 1 can be vibrated by the belt-shaped sheet 17. The seat 17 allows the user to receive a strong massage, and the vibrating spring unit 3 allows the user to receive a massage all over the body. Further, since the band-shaped sheet 17 has flexibility, it does not cause discomfort to the user who lies supine on the mattress device 1.

In the above embodiment, if the vibration generator is caused to vibrate in a so-called rhythm, it is possible to give the user not only a physical pleasure but also a necessary pleasure.

In addition, the belt-shaped sheet 17 to which the vibration generator 9 is attached is not limited to those mentioned in the above embodiments, but may also be a synthetic resin sheet or a foil-like metal sheet, which is essentially non-stretchable and flexible. It suffices if it has gender.

(Effects of the invention) As described above, this invention consists of stretching a non-stretchable and flexible belt-like sheet around the upper frame of the spring unit, and rotating the belt-like sheet in the longitudinal direction. Since the vibration generator is installed with the axes of the shafts almost perpendicular to each other, when the vibration generator is operated, the vibration is transmitted to the entire length of the belt-shaped sheet and is transmitted from the belt-shaped sheet to the spring unit via the frame line. It can be communicated to the whole. Therefore, according to the pinerest device equipped with the vibration generator of the above configuration, since vibration can be propagated over a wide area with one vibration generator, a large number of vibration generators must be used. It is more economical than the conventional method, and does not significantly impair the feel of the pinerest device.
