Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

Referring to FIGS. 1 to 7, the height-adjustable cervical pillow 200 using the height-adjustable mechanism 100 according to the present invention is shown in FIG. 1, and the height-adjustable mechanism 100 is the height-adjustable cervical pillow 200. The internally mounted appearance is shown in Figure 2.

As shown, the height adjustment mechanism 100 according to the present invention has an elastic plate portion 110 and a height adjustment portion 150 for adjusting the height of the elastic plate portion 110.

The elastic plate portion 110 has an elastic plate 111. Preferably, the elastic plate 111 is made of plastic, and through holes 113 are formed at intervals to bend in one direction. The through hole 113 is formed to be longer in a direction perpendicular to the bending direction rather than in the bending direction and also serves to reduce weight.

Reinforcement spokes 115 arranged in a direction perpendicular to the direction in which the elastic plate 111 is bent (hereinafter also referred to as the transverse direction) are formed on the elastic plate 111. The reinforcing spokes 115 increase the lateral strength and serve to reinforce the wings 117 protruding to both sides at both edges. Preferably, the reinforcing spokes 115 are also formed in the longitudinal direction.

As shown, mounting grooves 119 are formed in the elastic plate 111 in parallel at intervals in the transverse direction and arranged in the longitudinal direction. Each mounting groove 119 is equipped with an auxiliary elastic piece 120 made of metal. This auxiliary elastic piece 120 serves to reinforce the elastic plate 111 made of plastic and add elastic force. This auxiliary elastic piece 120 allows the elasticity of the elastic plate portion 110 to be appropriately adjusted to suit the intended use of the product. This elastic plate 111 can form the elastic plate portion 110 without the help of the frame 180, which will be described later. The reason is that the height adjustment unit 150 can adjust the degree of bending of the elastic plate 111 by pulling or releasing one end of the elastic plate 110 made of only the elastic plate 111, and the bending degree of the elastic plate 111 can be adjusted. This is because the height of the elastic plate 111 is also adjusted depending on the degree.

However, the height adjustment mechanism 100 according to the present invention is preferably configured to include a frame 180. The frame 180 helps the elastic plate 111 bend or unfold smoothly. The frame 180 has a guide portion 182 that guides the movement of the first end 111a of the elastic plate 111 and a rotation support portion 184 that rotatably supports the second end 111b. As shown in FIG. 3, the frame 180 is preferably formed by bending a metal rod member into a rectangular shape with an opening on one side. A rotation support portion 184 is installed inside the open side of the square to connect and support the guide portions 182 on both sides. The central portion of the rotation support portion 184 has a bent shape that protrudes toward the first end 111a.

Accordingly, the elastic plate portion 110 is preferably configured to have a portion coupled to the frame 180.

Preferably, rotational coupling portions 122 and 123 are formed at both ends of the elastic plate 111 constituting the elastic plate portion 110. The elastic plate portion 110 has a moving piece 125 coupled to be movable along the guide portion 182. Preferably, the guide parts 182 provided on the frame 180 are arranged in parallel with an interval left and right, and one moving piece 125 is installed on each guide part 182.

The elastic plate portion 110 has a moving axis 127. The moving shaft 127 is coupled to the rotational coupling portion 123 at one end. Both ends of the moving shaft 127 are coupled to both moving pieces 125 and are moved along the guide portion 182 together with the moving pieces 125.

A connecting piece 128 for connecting the first connecting member 152 is installed on the moving shaft 127, supports the first connecting member 152 at the center of the rotation support portion 184, and supports the first connecting member 152. A support piece 129 is installed to limit the movement path. The first connection member 152 is connected to the pulling operation unit 155 via this support piece 129. A metal wire that has high tensile strength and can be bent is suitable as the first connecting member 152. Any other metal wire may be used in place of the metal wire as long as it has a high tensile strength that can sufficiently withstand the degree of pulling in the present invention.

The pulling operation unit 155 adjusts the degree to which at least one of the first end 111a and the second end 111b of the elastic plate 110 is pulled toward each other, thereby adjusting the height according to the degree of bending of the elastic plate 111. It serves to adjust the .

In this embodiment, the height adjustment unit 150 connects the first end 111a to the second end 111b through the first connection member 152 and the first connection member 152 connected to the first end 111a. This is to pull towards or slow down the pulling on the first end (111a).

The pulling operation unit 155 is a part that can be configured in various ways because it can pull the first connecting member 152. The pulling operation unit 155 can adjust the degree of pulling by pulling or releasing the wire, which is the first connecting member 152, using a rack and pinion, etc., and allows the wire to be wound around the rotating body or by using a handle (as shown in FIG. 4). The degree of pulling of the first connecting member 152 can be adjusted by adjusting the degree of screw connection of the female threaded member 157 connected to the female threaded member 156) and the male threaded member 158 connected to the female threaded member 157. Depending on the direction in which the handle 156 is rotated, the distance between the first end (111a) and the second end (111b) of the elastic plate 111 decreases or increases, and the bending of the elastic plate 111 also increases or decreases accordingly. do. Accordingly, the height of the elastic plate 111 also changes.

In some cases, the degree of pulling may be adjusted by wrapping or unwinding the wire, which is the first connecting member 152, around the rotating body using a motor and a reduction gear. If it has a high tensile strength that can sufficiently withstand the degree of pulling, a fiber string, a synthetic resin string, or any other material made by mixing metal strings and fiber materials can be used instead of a metal wire.

In the state shown in FIGS. 2, 3, and 5, when the handle 156 is rotated in one direction and the first connecting member 152 is pulled, the first connecting member 152 rotates the moving shaft 127 to the rotation support ( 184). Accordingly, the moving axis 127 and the moving piece 125 move toward the rotation support part 184 along the guide part 182, and the distance between both ends of the elastic plate 111 is reduced. As the moving axis 127 moves toward the rotation support unit 184, the elastic plate 111 becomes increasingly bent, and the height of the elastic plate 111 increases as shown in FIGS. 6 and 7.

That is, when using the height adjustment mechanism 100 according to the present invention, the height of the cervical region of the height-adjustable cervical pillow 200 can be increased.

In the state shown in FIGS. 6 and 7, when the handle 156 is reversely rotated, the first connecting member 152 is released, and the moving shaft 127 is moved by the elasticity of the elastic plate 111 to the rotation support portion 184. move away from the side Accordingly, the moving shaft 127 and the moving piece 125 move in a direction away from the rotation support part 184 along the guide part 182, and the distance between both ends of the elastic plate 111 increases. As the moving axis 127 moves away from the rotational support 184, the elastic plate 111 gradually unfolds and the height of the elastic plate 111 decreases as shown in FIGS. 2 and 5.

Referring to Figures 8 to 10, depending on the case, the height adjustment mechanism 100 according to the present invention may be configured to pull or release both ends of the elastic plate 111 toward each other. As can be seen in FIGS. 8 and 9, the elastic plate portion 110 has an elastic plate 111 having rotational coupling portions 122 and 123 formed at both ends. The moving shafts 127 are respectively coupled to the rotational coupling portions 122 and 123 at both ends, and both ends of each moving shaft 127 are respectively coupled to the moving pieces 125 so as to be movable along the guide portion 182. It is combined. Accordingly, the two moving axes 127 can move along the guide portion 182 while being coupled to the moving piece 125. This embodiment illustrates that the first end 111a and the second end 111b of the elastic plate 111 move along the guide portion 182.

The height adjustment unit 150 of this embodiment has a first connection member 152 connected to the first end 111a and a second connection member 153 connected to the second end 111b. Metal wire is suitable for the first and second connecting members 152 and 153. As described above, the first and second connecting members 152 and 153 may be made of other materials. Referring to FIG. 8, the first connection member 152 starts from the pulling operation unit 155, passes through the second end 111b, and passes through the moving axis 127 of the first end 111a to the first end 111a. ), and the second connecting member 153 is carried out from the pulling operation unit 155, passes through the first end 111a, and passes through the moving axis 127 of the second end 111b to the second end 111b. is connected to The pulling operation unit 155 of this embodiment connects the first end 111a and the second end 111b from both sides of the elastic plate 111 through the first connection member 152 and the second connection member 153. It is meant to pull them towards each other or to slow down their pull towards each other.

Referring to Figure 10, the pulling operation unit 155 of this embodiment includes a first bevel gear 159 installed on the rotatable handle 156, and a second bevel gear engaged with the first bevel gear 159 on the outer peripheral surface. The gear 162 is formed and connected to the hollow shaft gear 160 and the first connection member 152 and the second connection member 153 in which a female spiral is formed on the inner peripheral surface, and is coupled to the hollow shaft gear 160 to form a hollow shaft. It is comprised of a male screw member 164 that pulls or loosens the first and second connecting members 152 and 153 according to the rotation direction of the gear 160.

That is, the height adjustment mechanism 100 shown in FIGS. 8 and 10 pulls the first end 111a and the second end 111b of the elastic plate 111 toward each other according to the rotation direction of the handle 156. The tension on each other can be released, and the height of the elastic plate portion 110 can be adjusted accordingly by adjusting the degree of bending of the elastic plate portion 110.

The rest is the same as described previously.

Referring to Figure 11, which shows another example of the pulling operation unit, in some cases, the pulling operation unit 155 connects the cylindrical drum 156a to the rotatable handle 156, and rotates the handle 156 to make the first connection. The member 152 can be pulled or released. If necessary, the second connecting member described above can be pulled together or released.

The rest is the same as described previously.

In the above embodiment, one height adjustment mechanism 100 according to the present invention is installed in a pillow as an example, but two height adjustment mechanisms 100 according to the present invention are installed on a pillow, bedsore prevention mat, cushion, backrest, etc. With more than one installed, the height can be adjusted for each part.

In addition, the pulling operation unit 155 can adjust the degree of pulling by pulling or releasing the connecting member using a rack and pinion, etc., and can use other methods such as winding the wire around the rotating body or using a female screw member connected to the rotating handle. The degree of pulling of the connection member can be adjusted by adjusting the degree of screw connection of the male thread member coupled to the female thread member. In some cases, the motor may be driven to pull or release the first connection member and/or the second connection member.

The height adjustment mechanism according to the present invention can be used to make pillows, bedsore prevention mats, cushions, backrests, etc. using air pockets or air bags. In addition, the present invention has the potential to be used to make other products that need to provide solid support while adjusting the height in a gently curved shape. The present invention has the potential to be used in products that help stretch or lengthen other body parts other than the cervical spine or change posture.
