The present invention proposes a new pillow that can easily and finely adjust the height of the back of the pillow (head) and cervical spine (neck).

The height adjustment pillow of the present invention controls the height by the position of the pillow by adjusting the height through the horizontal movable body and the lifting bar without complicated mechanical design or power generating means. In particular, the height of the elevating bar can be adjusted at a minute vertical interval by the minute horizontal movement of each horizontal movable body, so even a user who is sensitive to the height of the pillow can take a good night's sleep without feeling any change in the height of the pillow.

In addition, the height can be adjusted by the horizontal movable body and the lifting bar separately in the areas corresponding to the back of the pillow and the cervical spine, so that the height of the pillow can be controlled for each part according to the user's body shape or sleeping habit.

The functional pillow of the present invention includes a plurality of cushioning portions and a lift for height adjustment. Referring to the external perspective view of FIG. 1, the pillow 100 according to the present invention includes an upper cover 110, a first side wall and a second side wall 120a and 120b and a base plate 130, and a first side wall as necessary. And an auxiliary cushion 140 inserted between the second side wall and the second side wall. As shown in FIG. 2, a rotation knob 210 for controlling the height adjustment is exposed on the first and second side wall surfaces. The shape of the base plate 130 is preferably a rectangular structure having a predetermined thickness, whereas the upper surface of the first side wall and the second side wall and the structure of the upper cover may be formed in a wavy form so that the user can comfortably cut and lie down. have.

Meanwhile, although not shown, the outer surface of the pillow may cover the finishing fabric to protect the aesthetic effect and the internal components.

In the present invention, the first side wall and the second side wall (120a, 120b) are respectively disposed on the upper left and right side of the base plate, as shown in the cross-sectional view of Figure 3 and the cross-sectional view of Figure 4, respectively, two tunnels upwards The guides 125a and 125b are partially spaced apart from each other. That is, a pair of tunnel guides are formed on the first side wall and the second side wall, respectively, and the first tunnel guide 125a formed on the first side wall and the second side wall is functionally associated with each other, and the first side wall and The second tunnel guides 125b respectively formed on the second side walls are functionally associated with each other. The tunnel guide provides a passage in which the horizontal movable bodies 300a and 300b are inserted to move in the left and right directions, and guides the movement of the horizontal movable bodies. The tunnel guide may be formed over the entire horizontal length of the first side wall and the second side wall, or may be partially formed on the first side wall and the second side wall in consideration of the horizontal moving distance of the horizontal moving body.

The base plate, the first side wall and the second side wall, the upper cover may be formed of a cushioning material such as sponge, urethane foam, silicone foam, etc., and may vary the strength or density of each part as necessary. Natural materials (cotton, duck, goose down, buckwheat, crude, cypress, pine artifacts, etc.) can also be used. In the functional pillow according to the present invention, the first side wall and the second side wall fix and support the position of the rotation bar as described below, and guide the movement of the horizontal movable body, so that the first side wall and the second cover are lower than the base plate and the upper cover. It is preferable that the side wall is formed of a material having high strength or density.

First and second rotation bars are disposed in the two tunnel-shaped guides 125a and 125b formed upwardly from lower surfaces of the first and second side walls 120a and 120b, respectively. The center of the two rotation bar is exposed to the upper base plate. In addition, both ends of the first rotation bar and the second rotation bar penetrate through the first side wall and the second side wall to be exposed to the outer surfaces of the first side wall and the second side wall and are coupled to the rotation knob 210 described above.

On the other hand, between the first side wall and the second side wall, the base plate and the upper cover inner space (S) corresponds to the vertical movement space of the first rotation bar and the second rotation bar, where a sponge, cotton, or other cushion member is inserted Even if the height of the pillow is adjusted, the cushioning in the center of the pillow can be kept constant.

The first rotating bar and the second rotating bar are respectively inserted into a pair of the first horizontal moving body and the second horizontal moving body, and the rotating bar and the horizontal moving body are connected to each other by screwing. Since the first and second rotating bars and the pair of first and second horizontal moving bodies inserted therein have similar shapes and functions, the following description is directed to one rotating bar and a pair of horizontal moving bodies. And operation will be described.

Referring to FIG. 5, a pair of horizontal moving bodies 300a and 300b are inserted into the outer circumferential surface of the rotation bar 200. The rotating bar is a pipe-shaped structure extending in one direction, and the threads 220a and 220b are partially formed on the outer circumferential surface thereof. The pair of horizontal moving members 300a and 300b have a cylindrical through hole into which the rotating bar is inserted, and a thread is formed on the inner surface of the pair of horizontal moving bodies 300a and 300b. Therefore, when the rotary bar is rotated by rotating the rotary knob 210 coupled to both ends of the rotary bar, the screw is coupled to the outer circumferential surface of the rotary bar and disposed in the aforementioned tunnel type guides 125a and 125b to move vertically. The limited horizontal movable bodies 300a and 300b are movable horizontally, that is, in the longitudinal direction M of the rotation bar. The horizontal movement of the pair of horizontal moving bodies enables vertical movement of the lifting bar as described later. That is, in the functional pillow according to the present invention, the rotation of the rotary bar causes the horizontal movement of the horizontal movable body, and thus the vertical movement of the elevating bar occurs at the same time, thereby enabling partial height adjustment according to the position of the pillow.

The spacing of the threads of the rotating bar plays a very important role in the height adjustment of the pillow. When the thread spacing is small, the horizontal moving distance of the horizontal movable body can be finely controlled by the rotation of the rotation bar. In a preferred embodiment of the present invention, the thread spacing of the rotating bar is formed to be 1 mm or less so that the horizontal moving distance of the horizontal movable body can be finely adjusted to 1 mm or less, for example, 0.5 mm level when the rotating bar is rotated once.

In the present invention, the threads 220a, 220b are formed on the outer circumferential surface of the rotating bar in opposite directions. A pair of horizontal moving bodies inserted into the rotating bar also have internal threads formed to face each other in opposite directions of rotation. Due to the structure of the thread, the pair of horizontal moving members (300a, 300b) are moved in the opposite direction by the rotation of the rotary bar. For example, when the rotating bar is rotated in one direction, one horizontal moving object and the other horizontal moving object facing each other may be gathered close to each other, or when the rotating bar is rotated in the opposite direction, the two horizontal moving objects facing each other may be far from each other. According to a horizontal movement operation in which the first horizontal movable body and the second horizontal movable body are gathered or distant from each other, a lifting bar to be described later may move upward or downward.

The threads 220a and 220b of the rotating bar may be formed on the outer circumferential surface of the rotating bar as a whole, or may be partially formed on both sides of the outer circumferential surface of the rotating bar in consideration of the horizontal moving distance of the horizontal moving body.

In the present invention, a pair of horizontal moving bodies inserted into one rotating bar moves horizontally in association with rotation of the rotating bar, and inclined surfaces are formed in directions facing each other. 6A to 6C, the horizontal movable body 300 is formed in a structure in which the top surface is inclined with respect to the bottom surface, and the inclined top surface has two side walls 310a and 310b and the vertical movement of the lifting bar in the center thereof. The inclined movement guide 320 which guides is formed. The side wall and the inclined movement guide allow the movement path to be smoothly moved without moving away when the elevating bar moves in the vertical direction while sliding along the inclined surface in contact with the inclined surface of the horizontal moving body. In addition, a cylindrical through-hole 305 is formed at the lower side of the horizontal movable body to allow the above-described rotation bar to be inserted, and the horizontally movable horizontal movable body is interlocked according to the coupling with the rotary bar and the movement of the rotary bar. Threads are formed to enable this. The through hole is formed through the horizontal moving body rear and front, it can be formed on either or both sides with respect to the inclined movement guide.

(= tan30°) 수준으로 줄어들게 되어 보다 미세하게 베개 높낮이를 조절할 수 있게 된다. The inclination angle of the horizontal movable body inclined surface plays a very important role in the height adjustment of the pillow of the present invention. For example, if the inclination angle of the inclined surface is 45 °, the horizontal moving distance of the horizontal moving object and the vertical moving distance of the lifting bar inclined along the horizontal moving object inclination are the same (tan45 ° = 1), but the inclination angle of the inclined surface is set to 30 °. When lowered, the vertical movement distance of the lifting bar relative to the horizontal movement distance of the horizontal moving object

(= tan30 °) will be reduced to more finely adjust the height of the pillow.

The present invention is also inserted into the first tunnel guide (125a) and the second tunnel guide (125b) of the first side wall and the second side wall shown in Figure 3 horizontal of the first horizontal movable body and the second horizontal movable body It may further include a tunnel-type guide tube (see Fig. 7, 126) to guide the movement. The tunnel-shaped guide tube 126 is a rectangular cross-sectional structure having an empty interior having the same appearance as the tunnel-type guide, and a horizontal moving body is inserted therein to allow horizontal movement. The horizontal length of the tunnel type guide tube may be the same as the tunnel type guide, for example, and preferably does not exceed the horizontal length of the first side wall and the second side wall.

The tunnel guide tube may be formed of, for example, a thin metal plate and a plate, or a plastic of PE, PET, acetal, or ABS series, and the user's head inserts the pillow by inserting the inside of the tunnel guide on the first and second side walls. Even when pressed, the horizontal movable body is guided to allow stable horizontal movement.

The guide rails 126a and 126b linearly protruding along the moving direction of the first horizontal movable body or the second horizontal movable body may be formed on the inner wall of the tunnel-type guide tube. In addition, a protective wall 126c may be formed behind the tunnel-type guide tube to prevent the horizontal movable body from escaping to the outside. A through hole 126d is formed in the protective wall to allow insertion of the rotation bar, and the through hole 126d. It facilitates the rotation of the rotating bar and prevents the phenomenon that the horizontal movable body is biased to either the first side wall or the second side wall.

In this case, it is preferable that the horizontal moving body has a horizontal moving guide 330 linearly indented to correspond to the guide rail as shown in FIG. 8. The guide rail and the horizontal movement guide serve as a guide that allows the horizontal movable body to move more flexibly horizontally without any intervention inside and outside the tunnel type guide tube in engagement with each other.

As described above, the functional pillow according to the present invention includes a lifting bar which is mounted at both ends on the inclined surfaces of the pair of horizontal movable bodies and moves in the vertical direction according to the horizontal movement of the horizontal movable body.

These lifting bars are disposed on the inclined surfaces of the pair of first horizontal movable bodies and the pair of second horizontal movable bodies, respectively, and for the convenience of description, the structure and operation of the elevating bars will be described below. 9, the lifting bar 400 is disposed on the inclined surfaces of the pair of horizontal moving bodies 300a and 300b inserted on the outer circumferential surface of the rotating bar so as to face each other. The lifting bar moves along the inclined surface in conjunction with the horizontal movement (M) of the horizontal movable body by contacting the tip of the inclined movement guide (320 of FIG. 6A) formed on the inclined surface of the horizontal movable body, and as a result, in the vertical direction (H). Done.

Both ends of the elevating bar only need to be in contact with the pair of horizontal moving object inclined surfaces, and no separate coupling means is required. However, both ends of the lifting bar are inclined at the same angle as the horizontal moving body inclined plane so that mutual movements can be smoothly interlocked while maintaining both contact surfaces of the inclined plane of the horizontal moving body and the lifting bar. It is desirable to have a portion 410.

As such, in the present invention, the rotational movement (of the rotary knob and the rotation bar), the horizontal movement (of the horizontal movable body), and the vertical movement (of the lifting bar) are integrated at the same time to adjust the height of the pillow, and all such movements occur at the same time. It is possible with the manual operation by the user to rotate the rotary knob in one direction. In addition, by effectively designing the diameter of the rotation bar, the spacing of the threads formed on the outer circumferential surface of the rotation bar, the inclination angle of the inclined plane of the horizontal moving body, it is possible to make the height change of the lifting bar less with respect to the rotation of the rotation knob. As a result, the final pillow height adjustment is very finely controlled and can be adjusted so that the height of the pillow is not recognized by a user who is sensitive to the pillow height or a patient who has a head or face wound.

In the functional pillow of the present invention, the position of the first rotation bar and the second rotation bar is very important for partially adjusting the height of the pillow. 11 is a plan view showing the inside of the pillow according to an embodiment, the first rotating bar (200a) and the first lifting bar (400a) is disposed in the area corresponding to the cervical spine, the neck support portion of the pillow, the second rotation The bar 200b and the second elevating bar 400b can be seen to be disposed in an area corresponding to the back of the head, the back of the head. As such, by placing the first and second rotary bars on the cervical spine and the back of the head, the height of the pillow can be adjusted in response to various tastes and sleeping habits of the user.

On the other hand, in the center of the base plate between the first side wall (120a) and the second side wall (120b) in contact with or coupled to the first elevating bar (400a) and the second elevating bar (400b), the first elevating bar and the second elevating bar According to the vertical movement of the bar, the first lifting plate 410a and the second lifting plate 410b which move together in the vertical direction may be further disposed. The elevating plate moves vertically with the elevating bar while the elevating bar is balanced without biasing either the first side wall or the second side wall. In addition, the elevating plate may improve the contact feeling when the head touches the pillow by dispersing the pressure applied to the elevating bar in a larger area when the user uses the pillow. In addition, when the cushion member is additionally disposed between the elevating plate and the upper cover, the vertical movement of the elevating bar may also enable smooth vertical movement.

As described above, the functional pillow of the present invention may allow the head and cervical spine to be changed separately or simultaneously. For example, referring to FIG. 12, the height may be independently adjusted in the X region corresponding to the cervical spine and the Y region corresponding to the larynx.

According to the rotation of the rotary bar, a pair of horizontal moving objects gather together, and as a result, the lifting bar is raised upward, so that both the X area and the Y area are adjusted high, the user's cervical spine and the back contact area are all high. On the other hand, by rotating the rotation bar in the opposite direction so that the pair of horizontal moving objects away from each other it may be to lower both the contact surface of the cervical spine and the head of the user. In addition, the area where the cervical contact is lowered by lowering the X area is lowered and the surface contacted by the back of the head is increased by increasing the area of Y, or conversely, the area where the cervical spine is contacted by the height of the X area is lowered by lowering the Y area. As described above, the functional pillow of the present invention provides a pillow that is most suitable for the user's body by adjusting the height of the height of the cervical spine and the back of the head depending on the condition of the cervical spine and the head, the pillow usage habits, and the like. You can also correct the position of the cervical spine.

In the present invention, it is possible to change the height difference to a level of less than 1mm in adjusting the height of each position of the pillow. Therefore, even a user who is sensitive to pillow height may naturally experience a height change of 3 cm over a period of one month, for example, with a level change of 1 mm or less per day. In particular, it is very suitable for fine adjustment of the pillow height in patients who need treatment of the head or neck area.

Meanwhile, in the present invention, the upper cover may have cutouts 112a and 112b formed at the boundary points between the first side wall and the second side wall and the base plate center, respectively, as shown in FIG. 1 or 12. Such incision allows easier operation when the heights of the cervical vertebrae and the occipital region (X region and Y region) at the same time or separately are adjusted at the center of the pillow. In addition, by dividing the height adjustment area and the side wall area, the side wall is no longer face side when the user turns the pillow You can prevent it from running. As a result, for example, patients with scars or surgery on the face can unconsciously turn their heads when using the pillow to protect the wound or surgery from touching the pillow.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modified, modified, or improved.
