JPH01270818A - Snore and bruxism preventing pillow - Google Patents

Abstract

PURPOSE:To present a snore preventing pillow without malfunction by detecting the oscillating wave of a body to be generated in case of the snore and bruxism and changing the inclining angle of the pillow. CONSTITUTION:When the pillow is used, the cum surface heights of a pair of interlocking cum mechanisms 4 are made almost equal and the upper surface of the pillow is made flat. When the snore or bruxism of a sleeper is generated, the fine oscillating wave is generated in the body, detected and converted to an electric signal by an oscillating wave converting means 14. Then, a driving device 3 is operated by a board electric circuit 15 and a driving shaft 9 is revolved. After that, the revolution is transmitted to a revolving shaft 7 by a worm 10 and a gear 8. Then, one of a pair of decentering cums 6 rises in an upper direction and simultaneously, the other one falls down in a lower direction gradually. The inclining angle between the cum surface of the cum mechanism 4 and an upper frame 1b, which is supported by a strut 2a of a lower frame with being slidable, is changed. Thus, the direction of the head part of the sleeper is changed and the nose and throat are opened. When an attitude is obtained to well pass through breathing air, the snore, etc., is erased and a transmitting device is stopped.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a pillow that prevents snoring, teeth grinding, etc., and in particular detects the vibration waves of the sleeper's body that occur due to snoring and teeth grinding, and uses the detected signals as This invention relates to a pillow that mechanically changes the inclination of the pillow, thereby promoting circulation of breathing air of a sleeper and stopping snoring, etc.

[Problem that the invention attempts to solve]

Snoring, teeth grinding, and the like not only cause unpleasant noises that annoy people sleeping in the same room, but also have the potential to adversely affect internal organs such as the heart, and various measures have been attempted to suppress them. One example of this is the development of a pillow that collects the sounds of snoring and teeth grinding using a microphone, converts the sounds into electrical signals, and uses this to control a motor built into the pillow to change the head support inclination angle. There is.

However, if a device that detects sounds such as snoring and prevents sleepers from snoring uses a highly accurate sound collection device, the device will be activated by the sound of an air conditioner operating or other small noises in the surroundings. If the precision of the sound device is lowered, there is a problem in that the device will not operate even if snoring sounds occur, resulting in reliability problems.

Furthermore, since the conventional device has a structure in which the inclination angle of the pillow in the vertical direction is changed by an electric signal of the snoring sound, the range of change in the state of the head is small and sufficient effectiveness cannot be expected.

The present invention was made to solve the above problems,
The main purpose is to detect body vibration waves generated during snoring and teeth grinding and change the inclination angle of the pillow.
The purpose is to provide a snoring suppressing pillow that does not malfunction.

Another object of the present invention is to make it easier to open the 6A pharynx of a person by shaking the pillow in the left and right directions using a detection signal of body vibration waves.

[Means to solve the problem]

The above-mentioned object of the present invention is to provide a pile lower frame having an upward supporting column in the central part, and to engage the central part with the column of the lower frame so as to be able to swing to the upper part of the lower frame using the engaging part as a fulcrum. A supported pillow lower frame and a pair of interlocking cam mechanisms that are moved up and down in opposite directions by a drive device are arranged on both sides of the pillars of the lower frame, and the vertical movement of the pair of interlocking cam mechanisms creates a -L two-part frame. It has a transmission device that swings like a seesaw, and a vibration wave converting means that detects the vibration waves of the sleeper's body caused by snoring or teeth grinding and converts them into electrical signals, and based on the output signal of the vibration wave conversion means. This can be achieved by a pillow adapted to control the drive of the transmission.

The other objects of the present invention can be achieved by arranging the pair of interlocking cams a of the transmission device on both the left and right sides of the struts of the lower frame.

[Action of the invention]

When snoring or teeth grinding, vibration waves are generated in the sleeper's body. A vibration wave converting means such as a piezoelectric element that converts vibration waves into electrical signals is provided on the surface of the two-part frame of the pillow, that is, at the position where the head of the body contacts or at the position of the head. When vibration waves are generated in the body, such as when snoring occurs, the vibration wave conversion means senses the waves and converts them into electrical signals.

The detection output signal of the conversion means is subjected to necessary processing such as amplification in a desired electric circuit, and then used as a control signal for a drive device such as a motor that operates a pair of interlocking cam mechanisms.

When the drive device operates based on a signal from the vibration wave converting means, the pair of interlocking cam mechanisms move up and down in opposite directions, and the change in height changes the inclination angle of the pillow lower frame. In this way, changes in the angle of inclination of the pillow change the direction of the sleeper's head, which can reduce snoring and teeth grinding.

If a pair of interlocking cam mechanisms of the transmission device are placed on both sides of the fulcrum of the upper and lower frames, the sleeper's head will be swung left and right over a wide range due to the change in the angle of inclination of the upper frame, which will more reliably stop snoring, etc. Become.

[Embodiments of the invention]

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

The pillow body 1 is a lower frame 1 incorporating a transmission device to be described later.
a, tf above the lower frame, and an upper frame 1b movably supported.

The lower frame 1a is a frame body with an open upper part, and a pillar 2a for swingably supporting the upper frame 1b is integrally provided in the center thereof, facing upward, and an engaging part that engages with the tip of the pillar 2a of la. 2b, and is swingably supported by the pillars 2a of the lower frame la using the engaging portions 2b as fulcrums.

In the illustrated embodiment, each frame l
The upper frame 1b is generally cut at one or two places along the vertical direction of the a and lb, that is, along the axial direction of the sleeper's head, so that the upper frame 1b swings horizontally in a seesaw-like manner. It is composed.

A transmission device 5 is built into the lower frame 1a on both left and right sides of the support column 2a, and includes a pair of interlocking cam mechanisms 4°4 that are moved up and down in opposite directions by a drive device 3 such as a motor. ing.

In the illustrated embodiment, the pair of interlocking cam mechanisms 4.4 is an eccentric cam 6.
The cam's rotating shaft 7 is fixed to each rotating shaft at a different angle of 180 degrees, and a drive device 3 such as a motor drives the cam's rotating shaft 7.
By rotating the left and right eccentric cams, the height of the second dead center of the pair of left and right eccentric cams (6.6 force surfaces) can be raised and lowered alternately.

Incidentally, in the illustrated embodiment, a gear 8 is fixed to the rotating shaft 7 of each eccentric cam 6, and this gear 8 is connected to a common drive shaft 9.
At the same time as meshing with the worms 10 provided on both sides of the
By meshing the drive shaft 9 with the rotating shaft 11 of the motor 3 via the gear 12, the pair of interlocking cam mechanisms are operated simultaneously by the common drive device 3.

However, the transmission device 5 of the present invention is not limited to the illustrated embodiment; for example, a pair of interlocking cam mechanisms 4.4 may be directly fixed to both ends of the common drive shaft 9, or a pair of interlocking cam mechanisms 4. The cam mechanisms 4, 4 may be operated by separate drive devices.

Preferably, one end of the drive shaft 9 is protruded outside the lower frame, and an operating section such as a knob 7 or a crank is provided at the tip thereof, and the drive shaft 9 is rotated from the outside to connect a pair of interlocking cams. By returning the height of the cam surfaces of the mechanisms 4, 4 to the horizontal level, the -1: part frame 1b of the pillow can be adjusted to be flat.

14 is a vibration wave conversion means such as a piezoelectric element that is placed in contact with or close to the sleeper's head and senses the vibration waves of the sleeper's body, especially the head, generated when snoring or teeth grinding, and converts it into an electrical signal. In the illustrated embodiment, a desired number of these are provided at positions where they abut against the head of the pillow upper frame 1b. Of course, this vibration wave converting means 14 may be located inside or within the thickness of the upper frame la as long as it is at a position where vibration waves can be detected.

Alternatively, it may be brought into direct contact with the head of the Q person.

In addition, 15 in the figure is a drive device (
A printed board for an electric circuit output as a control signal for the motor) 3, and 16 a storage box for a power source (dry cell, etc.) for the drive device 3. Of course, the converting means 14, the electric circuit 15, the power source 16, and the drive device 3 are wired in a predetermined electric circuit.

Next, the operation of the above embodiment of the present invention will be explained.

In use, the drive shaft 9 of the transmission device 3 is operated by the external operating member 13 to set the height of the cam surfaces of the pair of interlocking cam mechanisms 4.4 to a height such as the gap, so that the top surface of the pillow is flattened.

When a person snores or grinds their teeth, minute vibration waves are generated in the body. This vibration wave is sensed by a vibration wave conversion means 14 such as a piezoelectric element and converted into an electric signal, which is amplified and other necessary processing is performed by a printed circuit board electric circuit 15, and serves as a control signal to operate the motor of the drive device 3. .

Thus, when a vibration wave is detected, the drive device 3 of the transmission device 5
operates, the drive shaft 9 rotates, and this rotational force is applied to the eccentric cam 6 by the worm 10 and gear 8 at both ends.
A pair of left and right interlocking cam mechanisms 4.4
Rotate.

The pair of left and right eccentric cams 6°6 of the interlocking cam mechanisms 4, 4 is 18
Since they are attached to each shaft 7 at different angles of 0°, one of the pair of eccentric cams 6.6 is tilted upward and at the same time the other is gradually lowered downward.

The upper frame 1b of the pillow is swingably supported by the cam surface of the interlocking cam mechanism 4 and the column 2a of the lower frame la, so that the heights of the left and right cam surfaces of the interlocking cam mechanism 4 move up and down in opposite directions. As a result, the horizontal inclination angle of the upper frame 1b of the pillow changes.

Therefore, the direction of the sleeper's head supported on the upper frame 1b changes. When you move, the inventive hole opens and you can breathe easily (in this position, snoring, etc. will disappear and the transmission will stop).

Even if snoring occurs again, you can immediately stop snoring by performing the same operations as above.

〔Effect of the invention〕

Since the present invention has the above-described configuration, it is possible to effectively eliminate snoring, which is not only good for the person's health but also prevents sleeplessness of the person in the same room. Since the pillow is operated by detecting the vibration waves of the body, there is no malfunction and a highly reliable anti-snoring pillow can be obtained.

In addition, by arranging the interlocking cam mechanism on both the left and right sides of the center of the pillow, the position of the head can be greatly changed from side to side. The effect is even more the same.
