It is fixed to 2 and the bottom plate 1. The support column 9 can prevent the upper surface plate 2 from tilting left and right under the influence of the height adjustment of the height adjustment devices 10F and 11R.

With such a structure, when the user adjusts the height of the pillow surface 20, the knob 53 is manually gripped and the rotating shaft 50 is pushed, so that the drive gear 5 moves backward against the elastic direction of the spring 7. 4 toward the imaginary line position shown by the chain double-dashed line in FIG. 4, releasing the engagement between the front end 80 of the stop ring 8 and the drive gear 5 to drive the rear drive gear 5 To be able to rotate.

By pushing the knob 53 by hand, the distance that the rotary shaft 50 slides rearward is small, and the tip 80 of the stop ring 8 can be disengaged from the rear drive gear 5. The drive gear 5 never disengages from the mesh with the racks 3 and 4.

At this time, when the knob is turned along the direction of the hands of the timepiece, as shown by the arrow in FIG. 3, the rack stages 32, 42 of the first and second rack members 3, 4 meshing with the drive gear 5 are , And at the same time, slide toward the left side or the right side in the figure, respectively. By the upward guides of the curved outer step portions 301, 401 of the two conduits 30, 40, the upper step portions 31, 41 of both rack members 3, 4 are pushed upward in an oblique direction, and the upper surface plate 2 is lifted. Therefore, the height of the pillow surface 20 becomes high as shown by the imaginary line indicated by the chain double-dashed line in FIG.

On the other hand, when the knob 53 is rotated in the direction opposite to the hands of the clock, the rotary shaft 50 and the drive gears 5 also rotate in the direction opposite to the hands of the clock, and the first and second rack members 3, 3. 4 rack stages 32 and 42 move to the left and right sides respectively in the figure, and at the same time, the upper stages of both rack parts 3 and 4 are guided by the lower guides of the curved outer step portions 301 and 401 of the two guide tubes 30 and 40. The parts 31 and 41 slide in the downward oblique direction, and the upper surface plate 2 is pulled down. Therefore, the height of the pillow surface 20 becomes low as shown by the solid line in FIG.

When the user adjusts the pillow surface 20 to the desired height and releases the knob 53, the panel 7 moves forward by pressing the rear drive gear 5, so that the tip of the stop ring 8 is moved. The part 80 returns to the position where it engages the gear of the drive gear 5. Under this condition, the tip 80 of the stopper ring 8 is engaged with the gear of the rear drive gear 5, so that the drive gear 5 cannot move. Therefore, the first and second rack members 3 and 4 cannot move, so that the height of the adjusted pillow surface is maintained at a predetermined height.

As described above, according to the above-described structure, the user can raise and lower the pillow surface 20 and adjust the height by simply turning the knob 53.

FIG. 5 is a view of a main portion of a pillow with a height adjusting device according to another embodiment of the present invention.

With reference to FIG. 5, this embodiment is a modification of the embodiment shown in FIGS. 1 to 4 that can be performed by electric operation. Therefore, only the relevant parts in terms of electric operation are shown, and the description of the first and second rack members and the like will be omitted.

With reference to FIG. 5, a stop ring 8 is provided near the drive gear 5 to allow its tip 80 to bite into or away from the gear of the drive gear 5. That is, the stopper ring 8 swings counterclockwise by the action of the pulled spring 7, and the tip 80 normally holds down the drive gear 5. An electromagnetic coil 80 is provided behind the stopper 8, and when a current flows through the electromagnetic coil 80 to generate a magnetic field, the stopper 8 uses a magnetic force that works against the pulling force of the spring 7 to cause the electromagnetic coil 80 to move. When it is sucked in the direction of, the tip portion 80 is separated from the drive gear 5.

On the other hand, a gear 54 having a large diameter is provided above the rotary shaft 50, and the gear 54 meshes with a gear 55 having a small diameter provided on the output shaft of the motor 12M. A bidirectional switch (not shown) for rotating the motor 12M in both directions is interlocked with the circuit of the electromagnetic coil 81, and when the motor 12M is started, the electromagnetic coil 81 also produces a magnetic field.

With such a configuration, when the user adjusts the pillow surface, the motor 12M is rotated in a desired direction only by turning on the bidirectional rotation switch (not shown), and the electromagnetic coil 81 is also moved. At the same time, since a magnetic field is generated, the stop ring 8 is prevented from swinging to the left due to the tension of the spring 7, and the tip portion 80 can disengage the drive gear 5. Therefore, the drive gears 5, 5 and the rotary shaft 50 are driven by the motor 12M via the gears 54, 55 as shown by the phantom line shown by the two-dot chain line in FIG.

When the drive gears 5 and 5 rotate, the first rack member 3 and the second rack member 4 meshing with the drive gears 5 and 5 move up and down by the method in the embodiment shown in FIGS. 1 to 4. Therefore, the pillow surface 20 is adjusted to the height desired by the user. After that, if a switch (not shown) is turned off, the motor 12M stops rotating, so that the magnetic field of the electromagnetic coil 81 disappears, and the stopper 8 is immediately pulled by the spring 7 and swings counterclockwise. The tip portion 80 meshes with the gear of the drive gear 5 to prevent the drive gear 5 from rotating, so that the pillow surface 20 is maintained at a predetermined height.

It should be noted that the above description is merely an explanation of the embodiment, and the height of the pillow, which is the object of the present invention, is adjusted by using a similar technique.

[0032]

As described above, according to the present invention, the drive gear that meshes with the racks of the first rack member and the second rack member is provided only when the user wants to change the height of the pillow. Since the upper plate that forms the pillow cushion can be raised and lowered by rotating it, the user can change the height of the pillow according to his mood.
