      The technical field to which the present invention pertains relates to a method of arranging signal generating sensors for starting a driving motor of an automatic height-adjustable pillow that can automatically adjust the height of a pillow according to a posture according to a change in the posture of a sleeper during sleep.

A lot of pillows have been produced so far, but the pillows that can automatically change the height of the pillow according to the change of sleeping posture have not been fully developed.

Related technologies are as follows.

Self-adjusting pillow (notice thread 1991-0000982)

Health Pillow for Automatic Height Adjustment (Application No. 20-2001-0010090)

Pillow that is transformed according to the human body posture by the sleep posture detection sense

                                         (Application No. 10-2001-0061080)

Pillow height adjustment device (application number 20-2004-0034370)

The above are the techniques known to date.

By the way, the automatic height adjustment pillow (notification thread 1991-0000982) is a distance between the pursuit of the present invention to adjust the height of the pillow by driving the motor by the user manually operating the switch before sleep, so only refer to the mechanism portion Let's reduce the amount of further discussion.

The automatic height adjustment health pillow (application number 20-2001-0010090) by installing a plurality of touch sensors or infrared sensor sensors arranged in order to detect a person lying down to detect a person lying down By sending a signal, the received microcomputer compares the input value and the received signal to determine the sleeping posture.

However, in this method, the sensor unit arranged under the shoulder of the sleeper may have a height difference from the floor due to its thickness, which may cause inconvenience to the sleeper's shoulder, and thus may interfere with sleep.

If you need to modify the yona mattress to solve this problem, it will be more complicated.

In addition, there is a possibility of malfunction due to difficulty in running out of water in the case of various posture changes occurring during sleep due to the simple arrangement of the sensors.

For example, if you cover your sensors with your arms extended in a sideways position, the sensors will recognize that you are lying directly and will not adjust height even if you are lying on your side.

In addition, the purchase price of a large number of expensive sensors and the development cost of the software will make the purchase price of the pillow much higher than usual.

In the pillow (Application No. 10-2001-0061080) that is transformed according to the human sleeping posture by the sleeping posture detection sense

When the sleeper wears a sleeping posture detection sensor for detecting a sleeping posture using a soft belt or the like on a part of the sleeping body, the sleeping posture sensor sends the sleeping posture information to the controller of the pillow by wire or wirelessly. Chooses how to determine sleeping posture

However, this method also requires the sleeper to wear a belt with a sensor attached to the torso, which may cause more inconvenience, especially in the hot summer months, and may also malfunction if the belt slips during sleep and the belt moves.

In order for the adopted sensor to be put into practical use in the above-mentioned abstract, the stability and performance must be verified through prototype production and numerous experiments.

In the pillow height adjustment device (application number 20-2004-0034370)

The sleep posture detection means is a transmission control unit worn on the user's head, and consists of a headband worn on the user's head and side switches respectively installed on both sides of the headband and a rear switch installed at the bottom to send a signal to the reception control unit. The reception control unit is configured to determine the sleeping posture of the sleeper.

However, this case also requires sleepers to wear bands on their foreheads, which is also causing discomfort to sleep disorders, and it may be more difficult in the hot summer season.

In addition, during sleep, the band may rotate or escape from the forehead, which can cause the malfunction.

As a method of transmitting and receiving signals wirelessly, transmission and reception devices inevitably increase the size of equipment and increase the cost.

As mentioned above, only incomplete technologies with these difficulties have been proposed.

        Until now, the automatic height adjustment pillow has not been fully developed because the sleeper's posture information could not be effectively obtained during sleep.

       In order to solve this problem, prior arts have attempted to obtain sleep posture information by forcing the sensor to sleepers.

But this created new, more difficult problems, which left them incomplete.

      The present invention is to obtain a new sleep information sleep position information by using this to replace the conventional sleeping posture information to automatically adjust the height of the pillow during sleep, through which a number of conventional problems are solved and automatic with sufficient practicality Create height-adjustable pillows to contribute to national sleep health and to enhance national competitiveness with technology

 Hereinafter, the accompanying drawings will be described in detail as an example.

        1 shows an example of a known automatic height adjustment pillow.

        (Notice thread 1991-0000982)

        Figure 2 also shows another example of a known automatic height adjustment pillow.

        (Application No. 20-2001-0010090)

        Figure 3 also shows another example of a known automatic height adjustment pillow.

        (Application No. 10-2001-0061080)

        Figure 4 also shows a fourth alternative example of the known automatic height adjustment pillow.

        (Application number 20-2004-0034370)

        The above techniques have already been examined in the technical field to which the invention pertains and the prior art in that field.

        Figure 5 shows a longitudinal cross-sectional view and a partially enlarged view of an example of the arrangement of the signal transmission sensor 5 for starting the drive motor of the automatic height adjustment pillow according to the present invention.

        In this example, the sensor 5 is disposed on the lower plate 2 so that the hinged cover plate 3 receives and transmits the information to the wide side to operate the sensor.

        The sensor placement of the pillow consists of a buffer port (1), a bottom plate (2), a hinged cover plate (3), a spring (4) and a sensor (5). As long as the posture is not disturbed, the person sleeps in the same posture as in the above figure, and the left and right sensor arrangements remain in the standby state without any influence.

       Figure 6 shows the posture of lying sideways, as shown in the figure, the hinged cover plate (3) lifted from the bottom of the buffer hole by the head falls down and comes into contact with the lower plate (2), which causes the sensor to operate. The control signal is sent to the controller, and the controller adjusts the height of the pillow by rotating the driving motor forward.

        At this time, the sensor arrangement on the right side remains in standby without any change.

        In this state, when the sleeping person turns to the right posture and head is returned to the center of the pillow, the sensor (5) in the sensing state returns to the termination state with the help of the spring (4) restoring force. Is a sensor placement method that adjusts the pillow height by rotating the drive motor in reverse.

        7 shows the state graphically.

        Fig. 8 shows the planar state of the pillow with some of the cushioning holes removed, and shows the arrangement of the hinged cover plate 3.

        Fig. 9 shows a planar state of another arrangement of the motor starting signal generating sensor 7 and is an example of a method of arranging the sensor inside the buffer opening.

        FIG. 12 shows the state of displacement of the sensor when the sleeper lies sideways in FIG.

        The sensor arrangement unit is operated by the shock absorber 1 itself or the sensor directly by the sleeper's head, and can be pressed and moved together like the shock absorber so that foreigners do not feel foreign body feelings.

        In addition, since the pillow cover is used on the surface of the buffer hole when the seal is used, there is almost no sense of foreign matter.

        The sensor allows small sensors to work together to respond to changes in the shape of the pillow and to form a common circuit to function as a single sensor.

        Fig. 10 is a plan view in which a portion is cut away, showing the front state of the sensor arrangement.

        FIG. 11 illustrates an enlarged state of the sensor unit of FIG. 10 and is a state diagram of the sensor when the sleeper is lying in a correct posture.

        Fig. 13 shows an example of another arrangement state of the motor starting signaling sensor 9, in which the arrangement 9 is arranged on the lower plate 2 and the associated fluid bag 8 has a buffer port and a lower plate. Is an example placed between

 When the fluid bag 8 connected to the sensor 9 is pressed due to the weight of the sleeper's head, the pressure inside the fluid bag is increased and the increased pressure is transmitted to the sensor so that the sensor detects this and emits a signal to the controller. When the pressure is returned to the original pressure when the pressure is removed, the sensor will signal again to start the control-drive motor again. The following operation procedure is the same as the above.

This sensor has a characteristic of operating mode that senses the pressure that is increased or decreased through the fluid and generates a signal as compared to the direct method of operation without medium.

Figure 14 shows a plan view of the pillow removed a portion of the buffer port can be confirmed the arrangement of the fluid bag

In addition, when the motor is stopped, the limit switch installed inside the pillow detects the position information of the moving part and sends a signal to the controller to stop the motor.The limit switch allows the maximum stroke of the pillow height adjusting means to be allowed. Up and down position movement is possible inside

       The present invention has solved the problems of the prior art

       This makes it possible to produce practical and competitive automatic height adjustment pillows.

The longer the period of use of the pillow, the more familiar you can put your head in the desired position during sleep, and the comfort and satisfaction can be added more and more, the automatic height adjustment pillow according to the present invention will be widely used in the future.
