Height adjustment pillow with bottom-mounted handle

Abstract

The present invention provides a height adjustment pillow including a lifting device for adjusting the height of an upper member with respect to a lower member, the lifting device comprising: a driveshaft having a lower end, which is penetrated through the lower member and protruded from the bottom of the lower member, and an operation handle provided on a lower end thereof; at least one or morerotation members mounted on the lower member so as to be rotatable around a vertical directional shaft; a power train equipment for transmitting the rotation force of the drive shaft to the rotation members; and a lifting operation equipment for converting the rotational motion of the rotation members into the linear motion in the vertical direction so as to lift the upper member.

Description

technical field [0001] Embodiments of the present invention relate to pillows utilized primarily to support the head while lying down. Background technique [0002] Disclosed in China Utility Model Grant Gazette No. 201822426 (CN201822426U), Republic of Korea Patent Gazette No. 10-1520430 (KR10-1520430B1), No. 10-1607997 (KR10-1607997B1) and No. 10-1645636 (KR10-1645636B1) There are user-adjustable height pillows. [0003] These height-adjustable pillows include a pillow body and a pillow cushion on the pillow body. The pillow body includes an upper part, a lower part, and a lifting device. The pillow cushion is arranged on the upper side of the upper part. Movement so that through the height adjustment of the upper part relative to the lower part, the user can adjust the height of the pillow to an extent that facilitates use or guides correct posture.

AI Technical Summary

Problems solved by technology

[0004] But this height adjustment pillow needs the user to operate directly, thereby should the operating handle of the lifting device (referring to the externally exposed) figure 1 The reference sign H) is arranged in the front or rear of the pillow main body, so it is impossible to cover the area where the operating handle is arranged with the pillow cushion. Because of this, if an impact is applied to the operating handle side, the impact will only be Issues that can be passed directly to the main body of the pillow

Of course, it may also cause the user to collide with the side part of the handle and be injured during use.

[0005] In addition, to put the pillowcase on the upper height adjustment pillowcase, which is generally made of fabric, so that the operating handle is exposed, it is necessary to cut or cut a part of the pillowcase so that the pillowcase is formed for the operating handle to pass through. Therefore, the above height adjustment pillow is required to perform the work of forming a hole or gap for exposing the operating handle, and there is a process aspect that needs to finish the edge of the hole or gap in order to prevent aesthetic deterioration, damage, etc. the cumbersome

[0006] Furthermore, since the operating handle is configured to rotate around a horizontal axis perpendicular to the vertical direction, there is a problem that the structure for transmitting the rotational force of the operating handle to the upper member to raise and lower the upper member is complicated.

[0007] On the other hand, since the height adjustment pillow as above has the strength that the lower part can protect the elevating device arranged between the upper part from the outside, if it is used on an uneven position such as a ground with a difference in height, it will figure 1 sloping to one side as in (a) or as figure 1 (b) is always moving, so there is a limitation in terms of use that can only be used stably and conveniently in a flat position

[0008] Moreover, there is the inconvenience that the height of the pillow needs to be directly adjusted one by one to a height suitable for the changed posture whenever the posture is changed from lying on the back to rolling over or the like during use.

As an example, it is troublesome to increase the height of the pillow when changing from a supine position to a side lying position, and to lower the height of the pillow when changing the position inversely.
