Description

{Height-Adjustable Pillow}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pillow, and more particularly, to a height-adjustable pillow capable of varying the height.

The pillow is configured to support the user's head to maintain a comfortable posture when the user is lying down or sleeping, and is generally configured to have a constant height and proper cushioning.

People take sleep in various postures. He lays down on a regular basis, lays down on his side, and falls down. In the case of cutting a pillow at a normal time, the back, the cervical spine, and back part of the human body form a straight line. Therefore, even if a relatively high pillow is used, the pillow will not feel a great inconvenience. The shoulder of one side and the side of the other side of the face, the cervical vertebrae are distorted due to the difference in distance. On the contrary, if a relatively high pillow is used, it may be relatively comfortable to sit on the side, but when laying on the bedside, it is difficult to expect a comfortable sleep because the head is lifted.

An embodiment of the present invention is to provide a height-adjustable pillow that can be adjusted to a height at which the user can feel comfortable.

The problems to be solved are not limited thereto, and other matters not mentioned can be clearly understood by those skilled in the art from the following description.

According to an embodiment of the present invention, An upper member disposed on the upper side of the lower member so as to be movable in a vertical direction; And a lift device for adjusting the height of the upper member by moving the upper member in the vertical direction between the upper and lower members, wherein the lift device is configured to move the upper and lower axes And at least one driven rotary member rotatably mounted to the drive rotary member; A driving shaft disposed so as to intersect the shaft for the drive circuit member; A gear type transmission mechanism for transmitting the rotational force of the drive shaft to the drive rotational member; A belt type transmission mechanism or a chain type transmission mechanism for transmitting the rotational force of the drive rotational member to the driven rotational member; And a lifting and lowering operation mechanism for lifting and lowering the upper member while performing linear motion in the up and down direction with respect to the other of the upper and lower members by converting the rotational motion of the driven rotary member.

The lower member includes: a bottom plate; And a side wall erected along an edge of the bottom plate. The driving rotational member and the driven rotational member may be mounted on the bottom plate and received in the inner space of the lower member. The drive shaft may pass through the side wall so that one end of the drive shaft can be directly operated by the user, and the end of the drive shaft may be exposed to the outside.

Wherein the elevating operation mechanism includes an inclined portion provided at a portion of the driven rotation member opposite to the other of the upper member and the lower member and provided so as to incline upward in one direction along the circumferential direction about the axis for the driven rotation member, An elevation guide member continuously provided on the inclined portion in the longitudinal direction of the inclined portion and having a plurality of engagement protrusions arranged at different heights; And a contact member protruding from the other of the lower member and the upper member and arranged to contact any one of the plurality of latching jaws according to the rotation angle of the driven rotation member. The plurality of locking protrusions may be formed as a stepped surface and a connecting surface, respectively. The stepped surfaces are spaced apart from each other along the longitudinal direction of the inclined portion and are spaced apart from each other and located at different heights. The connecting surfaces are formed as inclined surfaces connecting stepped surfaces having different heights, When the driven rotatable member is rotated, it can be moved up and down along the connecting surface to be displaced to another adjacent stepped surface.

Here, the stepped surfaces may be inclined downward in one direction along the circumferential direction about the axis for the driven rotary member.

The elevation control pillow according to an embodiment of the present invention may further include a height display device for displaying the elevation of the upper member as the elevation device moves.

The display device includes a rack extending downward along the vertical direction from the upper member; A pinion engaged with the rack; And a display member provided outside the lower member and rotatable together with the pinion and having a height display portion.

Means for solving the problems will be more specifically and clarified through the embodiments, drawings, and the like described below. In addition, various solution means other than the above-mentioned solution means may be further proposed.

According to the embodiment of the present invention, since the height of the pillow can be adjusted to a height at which the user can feel comfortable, the user can take a more comfortable sleep.

In addition, when applied to a multi-use facility such as a hospital, a hotel or a condominium, the user can adjust the height of the pillow according to his / her preference, thereby greatly improving the customer satisfaction.

Preferably, such power transmission mechanisms 822, 824, and 826 are configured so that the rotational directions of the driven pulleys 824 are all the same.

The elevating device 800 includes elevating operation mechanisms 832 and 834 for elevating and lowering the elevating panel 30 while converting the rotational motion of the driven rotary disks 814 to linear motion in the vertical direction with respect to the elevating panel 30 .

The lifting and lowering operating mechanisms 832 and 834 are provided with a lifting guide member 832 provided at the upper portion of the driven rotary disks 814 and adapted to rotate together with the driven rotary disks 814 respectively from the lower portion of the lifting panel 30, And a contact member 834 protruding toward the guide members 832.

Each lifting guide member 832 has an inclined portion 832a provided at an upper portion thereof and inclined upwards in one direction (counterclockwise with respect to FIG. 4) along the circumferential direction about the axis for the driven rotating disk 814 at the lower portion thereof, . The elevating guide members 832 have hooking protrusions 832b continuously provided along the longitudinal direction of the inclined portion 832a on the inclined portion 832a. Thus, the latching jaws 832b are disposed at different heights.

Each of the contact members 834 is in contact with one end of the engaging jaws 832b in accordance with the rotation angle of the lifting guide member 832 rotated together with the driven rotation disk 814. [ Preferably, the end of each contact member 834 is formed to be sharp.

Each of the latching jaws 832b is composed of a stepped surface 832c and a connecting surface 832d. The step surfaces 832c are spaced apart from each other at regular intervals along the longitudinal direction of the inclined portion 832a and are located at different heights. The connecting surfaces 832d are formed as inclined surfaces connecting stepped surfaces 832c having different heights. The contact member 834 can be moved up and down along the connecting surface 832d when the elevating guide member 832 is rotated together with the driven rotary disk 814 so as to be brought into contact with the adjacent other stepped surface at the present stepped surface.

In order to prevent the contact member 834 from being inadvertently moved up and down along the connecting surface 832d, the stepped surfaces 832c are moved along the circumferential direction about the axis of the driven rotary disk 814, (A counterclockwise direction with reference to Fig. 4).

The elevating device 800 includes a rotatable drive shaft 840, a drive shaft 840, and a drive shaft 840. The drive shaft 840 is disposed on the drive rotation disk 812 in a horizontal direction (for example, And a second power transmission mechanism 852, 854 for transmitting the rotational force of the drive rotation disc 812 to the drive rotation disc 812.
