Abstract

PROBLEM TO BE SOLVED: To apply even pressure to a head, a neck and shoulders of a urer for preventing the stiffness thereof by providing height adjustment means for adjusting the curved form of a sheet layed on a frame plate on which the head, neck and shoulders rest. SOLUTION: Height adjustment means 6 comprises a pair of opposite rotary plates 7 mounted on the inside of a frame plate; a rotary shaft 8 fixed between the paired plates 7; and a handle 9 rotating the shaft 8 together with the paired shafts 7 from the outside. The rotary plate 7 has a plurality of protrusions 7A, 7b protruding from the plate 3, and an upper end of the plate 7 is formed into a circuit arc shaped for curving the sheet 4 smoothly. The heights of the protrusions 7A, 7B, 7C are respectively different, and they are formed to be gradually made lower in this order. The back shapes of heads, necks and shoulders of persons are different from each other, and therefore, the height of projection 5 of the frame plate 3 is adjusted by turning the handle 9 by hand, thereby properly controlling the curved condition of the sheet 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pressure equalizing pillow,
When the head, neck and shoulders are placed on the seat while lying on the back which is considered healthy, the seat curves to the back of the head, neck and shoulders , Pressure is evenly applied from the seat to the head, neck and shoulders,
Thus, the present invention relates to a pressure-equalizing pillow that can prevent neck stiffness, shoulder stiffness, and the like, and can ensure a good sleep.

[0002]

2. Description of the Related Art Conventionally, pressure equalizing pillows have been disclosed in
No. 858 discloses this. Hereinafter, this pressure equalizing pillow is referred to as a conventional technology. Hereinafter, this conventional technique will be described with reference to the drawings.

FIG. 3 is a perspective view showing the prior art. As shown in FIG. 3, the prior art is formed by stretching a sheet 2 made of cloth over an installation frame 1 and has advantages such as light weight and excellent cushioning and ventilation. .

[0004]

However, the above-mentioned prior art has the following problems. That is,
Since only the head is on the seat 2, when lying down on the back, the seat 2 and the neck and shoulders do not adhere to each other, resulting in a level difference. Sleep is not promised.

Accordingly, an object of the present invention is to provide a head-side, neck-side, and head-side neck and a shoulder when the head, neck, and shoulders are placed on a seat while lying on the back which is considered to be preferable for health. An object of the present invention is to provide a pressure-equalizing pillow in which shoulders are evenly pressed, thus preventing neck stiffness, shoulder stiffness, etc., and ensuring a good night's sleep.

[0006]

According to the first aspect of the present invention,
U whose height is formed to be lower from the curved end toward the open end, and a convex portion is formed at an upper portion between the curved end and the open end
A character-shaped frame plate, a sheet stretched on the frame plate, a seat on which a head, a neck, and a shoulder portion are placed, and adjusting the height of the convex portion of the frame plate to adjust the curved shape of the sheet. It is characterized by comprising height adjustment means for adjustment.

According to a second aspect of the present invention, the height adjusting means comprises: a pair of rotary plates attached to the inside of the frame plate so as to face each other; a rotary shaft fixed between the pair of rotary plates; The rotating shaft comprises a handle for rotating the rotating shaft together with the pair of rotating plates, wherein the rotating plate has a plurality of projecting pieces projecting from the frame plate and having different heights. Things.

[0008] The invention according to claim 3 is characterized in that the sheet is a cloth or a net.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the pressure equalizing pillow of the present invention will be described with reference to the drawings. FIG. 1 is an assembled perspective view showing an equalizing pillow of the present invention, and FIG. 2 is a front view showing a use state of the equalizing pillow of the present invention.

In FIGS. 1 and 2, reference numeral 3 denotes a wooden or resin frame plate formed in a U-shape. 4 is a frame plate 3
Is a cloth or a net-made sheet stretched on the upper surface. The lower surface of the frame plate 3 is formed horizontally, and the height decreases from the curved end A of the frame plate 3 toward the open end B.
A convex portion 5 is formed substantially at the upper center of the open end B. This means that when the head, neck, and shoulders are placed on the seat 4, the seat 4 is curved to conform to these back shapes, and pressure is evenly applied from the seat 4 to the head, neck, and shoulders. This is to make it take.

6 is to adjust the height of the convex portion 5 of the frame plate 3,
It is height adjusting means for adjusting the curved shape of the seat 4. The height adjusting means 6 includes a pair of rotating plates 7 attached to the inside of the frame plate 3 to face each other, a rotating shaft 8 fixed between the pair of rotating plates 7, and the rotating shaft 8. It comprises a handle 9 for rotating with a pair of rotating plates 7 from outside. The rotating plate 7 has a plurality of projecting pieces 7A, 7B, 7C protruding from the frame plate 3. Protrusions 7A, 7B, 7C
Is formed in an arc shape in order to smoothly curve the sheet 4. The heights of the protruding pieces 7A, 7B, 7C are different from each other, and are gradually reduced in this order. It is needless to say that the number of protruding pieces is not limited to three.

Since the equalizing pillow of the present invention is configured as described above, as shown in FIG. 2, the equalizing pillow of the present invention is placed on a rug 10 such as a futon or a mat, and If you sleep on your back with your head, neck and shoulders on top,
Since the seat 4 is curved in the back shape of the head, neck and shoulder, pressure is equally applied to the head, neck and shoulder from the seat 4. Thus, neck stiffness, stiff shoulders, etc. can be prevented,
A good night's sleep is promised. In particular, since the head is very heavy, if the pressure is not evenly applied to the entire occiput from the seat, an uneven load is applied to the neck and shoulders, causing neck stiffness and stiff shoulders. According to this, since pressure is equally applied from the seat to the neck and shoulders, as well as to the back of the head, neck stiffness and shoulder stiffness do not occur.

The back shape of the head, neck and shoulders differs depending on the person who sleeps.
The height of the convex portion 5 is adjusted, whereby the bending degree of the sheet 4 is appropriately adjusted.

It is noted that a person turns over several tens of times a night. It is said that this is to avoid blood circulation when sleeping for a long time in a certain shape, which worsens blood circulation. However, for health reasons, sleeping on the back is most preferred. According to the present invention, as described above, the head, neck, and shoulders are evenly pressured from the sheet, so that blood circulation does not deteriorate in these parts, and sleep in a supine position. Can be maintained. For this reason, the present invention is particularly suitable for pregnant women who need to sleep on their backs.

[0015]

As described above, according to the present invention, the height is reduced from the curved end toward the open end.
A sheet on which a head, a neck, and a shoulder are placed is placed on a U-shaped frame plate having a convex portion formed at an upper portion between a curved end and an open end, and the height of the convex portion can be adjusted. As a result, the advantages of the prior art, such as light weight and excellent cushioning and breathability, are provided as they are, and further, the following useful effects are provided. That is, the seat is the head,
Being able to curve to the back of the neck and shoulders, the seat can evenly apply pressure from the seat to the back of the head, neck and shoulders, allowing the head to stay in the head even after prolonged sleep. The neck, neck and shoulders are not overly stiff, no neck stiffness, no stiff shoulders, etc., and a good night's sleep is promised.
