When people sleep, they don't sleep right away, they just lie on their side. When sleeping and lying down on the pillow and lying on the side, the height of the head and neck of the user in contact with the pillow from the bottom of the structure of the human body is changed. In order to ergonomically straighten the user's head with the body, the height of the pillow itself should be low when lying down and the height of the pillow should be high when lying on its side. However, it is impossible to raise or lower the pillow while you sleep.

Looking at the prior art in this field, the prior art (utility model registration application No. 95-29130) has already been disclosed by the applicant of the present invention. The height conversion pillow according to the prior art was to simply support the head through the height conversion function structure without the distinction between the neck and the head.

However, such a conventional pillow is not only provided with a structure that can maintain and protect the cervical spine C shape of the user's neck, but also the rigidity of the structure is transmitted to the back of the user's head, so that the user can use the pillow. There was an uncomfortable problem that can not relieve fatigue.

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to automatically convert the height of the site in contact with the human body ergonomically adaptive to the human body of the lying posture when the user lays on a pillow It is to provide a pillow with a built-in height conversion elastic device.

According to an embodiment of the present invention for achieving the object as described above, in the pillow with a built-in automatic height conversion elastic device, the pillow is a cushion cushion having a cushion function of a memory foam (foam) material with a predetermined thickness A pair of fixing shape members having a predetermined height therein are formed apart from a predetermined interval to form a pillow as a whole, and the height automatic conversion device is built between the fixing shape members. Between the lower plate portion and the upper plate portion integrally coupled with the cushion portion, the hinge pins are cross-coupled with each other to be rotatable to form a pair of X-shaped levers, and one side end is hinged to the guide portion integrally formed with the upper and lower plate portions. Is fixed in place by a pin rotatably, the other end is moved along the guide groove of the guide portion formed integrally with the upper and lower plate portion The lever members coupled to the guide member, and the U-shaped support portions and one end portion are fixed to the hinge pin connecting the flow end of the lever member so as to extend from the widthwise side of the upper and lower plate portions to support the head of the human body. And a return spring having a constant spring constant and a spring position fixed to the other end of the return spring to change the position of the return spring, the variable end being configured, and the spring position varying the positions of both ends of the return spring through the variable end.

5A and 5B are conceptual views schematically showing an operation state of lever members forming a pair of X-type levers of a pillow having a height automatic conversion elastic device according to the present invention.

Looking at the operation of the present invention.

According to the present invention, one end of the lever members forming a pair of X-shaped levers are fixed to the fixed end and the other end is the flow end, and the one end 136b of the return spring 136 is fixed to the flow end. In the state (see FIG. 3), as shown in FIG. 5A, the lever members maintain a constant height h1 and an angle ?? 1, and when the upper plate portion 120 is loaded with a predetermined level or more, the upper plate portion 120 is applied. As the height h1 decreases toward the lower plate 110, the return spring 136, which is caught on the flow stage of the lever members, is pulled out, thereby increasing the restoring force of the return spring 136, but the return spring 136 is increased. The restoring force of the upper plate part 120 is distributed toward the fixed end direction and the upper plate part 120 is pushed up so that the restoring force of the upper plate part 120 is maintained without a great change in the initial load. As shown in FIG. 5B, the lever member forming the pair of X-shaped levers together with the lower plate part 110 may be formed at both ends of the return springs 136 so as to reach a predetermined level of angle ?? 2 and height h2. By changing the position, the restoring force of the return spring 136 itself becomes very strong.

On the other hand, if it is assumed that the lever members are almost horizontal, the restoring force of the return spring 136 itself is the highest, but the restoring force is applied to the 100% fixed end, so that the force to push up the upper plate portion 120 becomes zero, In the present invention, when the upper and lower plate parts 110 and 120 are in contact with each other, the force to push up the upper plate part 120 does not become zero, and the upper and lower plate parts 110 and 120 are paired with the upper and lower plate parts 110 and 120 so that a slight force remains. When the lever members constituting the lever are not horizontal and are mounted at a slight acute angle, the pressing members are removed when the side members are turned sideways to restore the upper plate portion 120. Under these conditions, the height is automatically converted to the person's lying position.

The following settings are required to meet the above conditions.

When the upper plate portion 120 is in the upper limit (not shown, refers to a state defined in height as shown in Fig. 5a or 5b), the supporting force should be set to be weaker than the weight of the head when lying right, and sideways It should be set stronger than the weight when lying down.

In addition, when the upper plate portion 120 is at the lower limit (which means no more lever members are lowered) it is necessary to mount so that the force to push up the upper plate portion 120 remains.

When the upper and lower plate portions 110 and 120 are in contact with each other, the force for pushing up the upper plate portion 120 does not become zero and the force for pushing up the upper plate portion 120 remains slightly. When the fixed end and the intersection point is not horizontal and the intersection is set slightly higher than the fixed end, the force to push up the upper plate portion 120 remains.

When lying on the side, the weight of the head on the pillow is only half the weight of the actual head, so the body and the head are in a straight line for a comfortable sleep. When the upper plate part 120 and the lower plate part 110 are almost in contact with each other (see FIG. 6), the body 120 forms a straight line when the person is directly lying down, and the force to push up the upper plate part 120 is the head. It is possible to take a comfortable sleep in a stable state without being affected by the strong restoring force of the return spring 136 because it does not reach the weight of.

When the user is lying on the side again, the weight of the head applied to the upper plate portion 120 is reduced or almost eliminated, and at the same time the tension of the return spring 136 is eliminated, so that the upper plate portion 120 reaches the upper limit.

6 and 7 are use state diagrams showing the use states of FIG.

Referring to Figures 6 and 7, the user can see the state of the user lying directly on the pillow 500, lying on the ground, and can also see the state of the user lying on the ground side lying on the pillow 500.

Through this, the height of the automatic height conversion elastic device 100 is automatically converted state, it can be seen that the difference between each other h3, h4. In this way, the pillow 500 according to the present invention is automatically converted in height according to the user's use state.

As described above, the pillow with a built-in automatic height conversion elastic device according to the present invention has the effect that the user can take a comfortable sleep by converting the height of the pillow by adapting itself to the weight of the head according to the person's lying position There is.

When the pillow with built-in automatic height resiliency device of the present invention is laid down, the pillow protrudes toward the neck and is extended at right angles as the pillow is raised so that the upper part of the human shoulder can push the pillow out. There is no effect and thus the pillow does not fall off.
