Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pillow whose height automatically and slowly changes according to the sleeping posture.

[0002]

[Prior art]

 Conventionally, the height of the pillow is constant, and if you lie down on your back in a supine or sideways position during sleep, the height is just right in the supine position, but it is too low when lying sideways, or vice versa. Is too high, causing discomfort. Therefore, a pillow with a different height was developed, but this pillow is always kept at a constant height by the force of the spring.If the load applied to the pillow is large, the pillow will be low, and if the load is small, the pillow will be low. Is high.

However, although the height of pillows using these springs changes depending on the magnitude of the load, the weight of the head in the lateral or supine position generally does not change much to the left. Therefore, the height of the pillow does not change depending on the posture. Also, even if it changes, the height of the pillow changes abruptly, so it is possible to prevent sleep by receiving an impulse during sleep.

Then, the one of Japanese Utility Model Laid-Open No. 3-35772 was developed. This is provided with a substantially horizontal head mounting plate that is supported slidably in the vertical direction above the base, and a cylindrical body whose tip is opened from either of the base and the head mounting plate facing each other. To the other side, insert and fit the tip of the cylinder protruding from the other side into this cylinder to create a sealed chamber with these cylinders, and provide a small-diameter exhaust hole in this sealed chamber. Further, a frustoconical constant load spring spring is provided between the base and the headrest plate.

[0005]

[Problems to be solved by the device]

 However, when the head rest plate moves up and down with respect to the base, this pillow tilts the head rest plate up and down when the load is applied to the end of the head rest plate, and remains in that state. You may not be able to rest your head. Also, in order to loosen the vertical movement speed of the head mounting plate with respect to the base, the upper and lower cylinders are slidably fitted together to create a closed chamber, but it is extremely difficult to adjust the speed with this cylinder. .

According to this invention, the position of the head changes due to such changes in the posture of the supine or sideways during sleep, but the height of the pillow changes slowly according to the change in the position of the head. The purpose is to provide.

[0007]

[Means for Solving the Problems]

 Therefore, the idea is to put a lid on the box and fit them together, and arrange a packing material in this fitting gap to provide a vertically expandable and contractible sealed box, and the rotatable box is rotatable on both sides. An X-shaped frame body is provided, and slide guides are provided between the corresponding tips of the X-shaped frame bodies on both sides by means of horizontal rails, and a conical trapezoidal shape for biasing the lid body upward in this closed box. The fixed load springs are installed, and the upper and lower edges of the sealing cover that loosely covers the fitting edges of the box and lid are fixed to the outer periphery of the lid and the box, respectively. An exhaust hole is provided. In the above constant load spring, the change in load and the amount of spring deflection are not proportional, and when the change in load is small, the amount of deflection does not change much.

Further, in the above structure, a clock is provided at an appropriate location on the box or lid, and the clock instantly outputs a time instant with each operation of the switch. Further, the clock is provided at an appropriate location on the box or lid. There may be a case where the above-mentioned clock switch is provided.

[0009]

[Action]

Now this pillow is unloaded, the constant load spring is extended, and the headrest is at a high position with respect to the base. Then, when the user of this pillow lays down and puts his head on the pillow and turns sideways, the weight of the head, for example, a load of about 5 Kg causes the spring to contract, and as shown in FIG. Thus, the head (a) becomes almost horizontal, and the height of the pillow (b) becomes α ₁ and becomes stable. From this position, when the user (C) is in the supine position as shown in FIG. 1 (B), the pillow (B) is raised and the neck is bent, and the weight of the head (A) becomes heavier and the pillow ( The spring spring in (b) is further contracted, and as shown in FIG. 1 (C), the head mounting plate is gradually lowered so that the head (a) becomes substantially horizontal. Here, the height of the pillow (b) is α ₂ . Then, when the user (c) is turned sideways again, as shown in (D) of FIG. 1, the pillow (b) is low and the tip of the head (a) is lowered. In this state, the weight of the head (a) is lowered. Since the pillow (b) is slightly lighter, the pillow (b) gradually pushes up the head (a) by the force of the spring bane, and stops when the head (a) is in a substantially horizontal position, as shown in Fig. 1 (A). Like The difference in height of pillows under a constant load, α ₁ −α ₂ = α, is about 50 to 60 mm.

Further, when the height of these pillows changes, air is filled in the closed box composed of the lid and the box, but when the lid is lowered by the load, the air is filled with the lid. The air gradually leaks from the fitting gap between the box and the box body, enters the airtight cover, and the air is filled in the airtight cover, and the air gradually leaks to the outside through the small-diameter exhaust hole provided in the airtight cover. Therefore, the lowering speed of the lid becomes very slow. Further, when the lid is raised, air is sucked from the small-diameter exhaust hole and gradually rises as described above.

Further, when the lid body moves up and down with respect to the box body, since the lid body is supported by the slide guide, the X-shaped frame body of the slide guide rotates integrally, and the lid body moves smoothly. It goes up and down and is always horizontal.

Further, in the case where a clock is provided, when the user presses the switch or touches it lightly, the clock utters the time, and the user does not look at the clock and outputs the voice in the same posture. You can know the listening time.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 2 to 7 show an embodiment of the present invention, in which a box body 1 having an open upper end is covered with a lid body 2 and fitted together, and a packing material 3 is provided along the outer periphery of the upper edge of the box body 1. By this, the fitting gap between the box body 1 and the lid body 2 is closed, and a vertically expandable / contractible closed box 4 is provided, and a central shaft 5 is provided on both sides in the closed box 4 so as to be rotatable. A frame body 6 is provided, and slide guides 8 are provided between the corresponding ends of the X-shaped frame bodies 6 on both sides thereof by providing a cross rail 7 respectively.

The upper and lower horizontal rails 7 on one side of the slide guide 8 are rotatably fixed to the box body 1 and the lid body 2 by means of a key type fixing tool 9, and the upper and lower horizontal rails 7 on the other side have a long width. It is rotatably fixed by a fixture 10, and each horizontal rail 7 is fixed in the long-width fixture 10 so as to be slidable by a certain width. Therefore, the lid body 2 is supported by this slide guide 8, and the vertical movable width of the lid body 2 with respect to the box body 1 is regulated by this slide guide 8.

Further, in the closed box 4, an appropriate number of frustoconical constant-load spring springs 11 having an upper end fixed to the lid body 2 and a lower end fixed to the box body 1 are provided. The load spring 11 always pushes the lid 2 upward. In this constant load load spring guide 11, the change in load and the amount of spring deflection are not proportional, and the amount of deflection does not change much when the change in load is small.

Further, there is provided a sealing cover 12 made of rubber or the like which loosely covers the fitting edges of the side surfaces of the box body 1 and the lid body 2, and the upper and lower edges 12a and 12b of the sealing cover 12 are respectively provided in the box body. It is fixed to the outer periphery of the lower surface of 1 and the outer periphery of the upper surface of the lid 2, and a small-diameter exhaust hole 13 is provided at an appropriate position of the hermetic cover 12 which is not adhered to the box 1 or the lid 2.

Further, a clock portion 15 is provided in the recess 14 provided on the lower surface of the box body 1. Further, a speaker 16, a micro switch 17 and a lever 18 of the switch 17 are provided on a side surface of the lid body 2 inside the closed cover 12. As shown in FIGS. 5 and 6, one end of the lever 18 is supported by a fulcrum pin 19, and the other end is always pulled up with a spring 20 interposed at the other end. The lever 18 resists the force of the spring 20. When is pressed, the actuating rod of the micro switch 17 provided adjacently is pressed, whereby the timepiece unit 15 is operated, and the time at that time is sounded by the speaker 16. Further, the clock of the clock unit 15 displays the time, and the time can be known visually from the outside.

Further, an appropriate cushion material 21 is provided so as to cover the side surface and the upper surface of the closed box 4, and the exterior material 22 covers the entire outer circumference of the closed box 4 from above the cushion material 21. The exterior material 22 is provided with a window 23 through which the timepiece portion 15 can be seen. The cushion material 21 and the exterior material 22 are made of air-permeable material.

In the case of this embodiment, the lid body 2 is located at the uppermost position by the constant load spring 11 when no load is applied. Therefore, when the user uses this as a pillow, if the user lies down on his back and places his head on the pillow, the lid body 2 is lowered against the force of the constant load spring 11. At that time, the air filled in the closed box 4 flows into the space 24 between the closed cover 12 and the closed box 4 from the fitting gap between the box 1 and the lid 2. At that time, since the packing material 3 exists in the fitting gap, the air flows only little by little. Moreover, the space 24 in the closed cover 12 is small, and the air is immediately filled with the air, and the air is exhausted little by little from the small-diameter exhaust hole 13 of the closed cover 12.

Therefore, the lowering of the lid body 2 is performed very gently. Then, when the user turns over and turns sideways, the load slightly changes, and the lid body 2 is slightly lifted by the force of the constant load spring 11. However, at that time, the lid 2 cannot be lifted unless air is put into the closed box 4. Therefore, the outside air is sucked little by little from the exhaust hole 13 of the hermetic cover 12, and the air in the space 24 of the hermetic cover 12 is further sucked from the fitting gap to inflate the hermetically sealed box 4, but these move only little by little. As it has a structure that does not break, the rising speed is extremely slow.

Further, in the above-described embodiment, since the lid body 2 is supported by the slide guide 8 with respect to the box body 1, when the lid body 2 is moved up and down, it is guided by the movement of the slide guide 8 and smoothly. In addition, even if a load is applied to the end portion of the lid body 1, the lid body 2 always moves up and down while being kept substantially horizontal. Thus, in this embodiment, when the user of this pillow turns over and turns around, the height of the pillow changes slowly, so that the user can always sleep comfortably.

When the user of this pillow wants to know the time, he / she presses the lever 20 on the side of the pillow to turn on the micro switch 17, and the clock unit 15 is activated to display the time from the speaker 16 at that time. Promptly utters a voice so that the user can know the time in the same posture. When the pillow is turned upside down, the time display of the clock section 15 can be seen through the window 23 of the exterior material 22.

In the above embodiment, both ends of each truncated cone are directly fixed to the box body 1 and the lid body 2. However, the present invention is not limited to this, and as shown in FIG. A pantograph-shaped slide guide 25 that can be connected to and connected to each other is provided, and both ends of the constant load spring spring 11 are connected to the left and right sides of this slide guide, and the same effect as in the above embodiment is obtained. Further, the number of the constant load spring 11 and the number of the speakers 16, the micro switches 17 and the levers 20 are arbitrary.

[0024]

[Effect of device]

 The present invention is configured as described above, and the height of the pillow changes slowly when the user of the pillow turns over and turns, so that the user can always use a pillow of a suitable height and not be in an uncomfortable position. I can sleep comfortably.

In addition, when the height of the pillow changes in this way, it changes very slowly, and moreover, even when a load is applied to the end of the pillow, the upper surface of the pillow always changes while maintaining a substantially horizontal direction. The head is always stable, does not give unnecessary irritation to the user, and can sleep well.

In addition, the one provided with a clock that outputs the time by voice can be known in its posture by simply pressing the switch while sleeping, which is extremely convenient and allows the voice to be output inside the pillow. Therefore, it can be heard even at an extremely low volume and can be kept out of the way of others.
