The present invention relates to a pillow, and more particularly to an adjustable pillow.
The cervical spine structure of a normal human body presents a C-shaped lordotic state. When people who look down to look at their mobile phones for a long time, the C-shaped arc of the cervical spine disappears and forms a straight line, which is prone to many discomfort symptoms such as soreness and numbness in the neck, shoulders and arms. When the natural curvature of the cervical spine disappears, the arrangement of the upper and lower vertebral bodies of a certain segment of the cervical spine is abnormal, resulting in: 1. The surrounding soft tissues are distorted, causing pain in the segmental vertebral body. 2. The nearby vertebral facet joints are under torsional pressure, which causes pain near the vertebral body. 3. The compression of the intervertebral disc between the upper and lower ends of the segment is uneven, which will cause the pressure at the front end of the intervertebral disc to be greater than that at the back end, so that the intervertebral disc protrudes backward and compresses the spinal nerve root on either side, and the dermatome innervates also feels numbness and pain, which is why cervical spondylosis can also cause soreness, numbness and pain in the shoulders, upper back, upper limbs, and fingers.
However, the so-called neck supporting pillow generally only emphasizes that the curvature of the cervical spine, so the material used at the contact point of the cervical spine is often soft and has no supporting effect, let alone correcting effect. In addition, some pillows may employ harder materials to emphasize the support function, but arc degree required by each person is different, if the support strength is not properly adjusted, the user might feel uncomfortable or even get injured, therefore, there is a need for improvement.
Therefore, it is desirable to provide an adjustable pillow accessory to mitigate and/or obviate the aforementioned problems.
An objective of the present invention is to provide an adjustable pillow which can provide more support and correction.
In order to achieve the above mentioned objective, an adjustable pillow has: a lower member, an upper member, and a lifting mechanism; the lower member having a neck supporting section at one end and an assembly space adjacent to the neck supporting section, the upper member having an assembly protrusion and a head supporting section extending from the assembly protrusion; wherein the assembly protrusion is capable of being correspondingly disposed in the assembly space such that the head supporting section is lower than the neck supporting section, and the assembly protrusion further comprises an accepting space at a bottom side for accepting the lifting mechanism for mounting between the lower member and the upper member.
Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
First, please refer to
Moreover, the assembly space 12 of the lower member 10 and the assembly protrusion 21 of the upper member 20 have corresponding concave-convex structures. Two opposite inner sidewalls of the assembly space 12 have a plurality of vertical engaging grooves 121, and another two inner sidewalls have at least one positioning rib 122 and two positioning grooves 123 on each side of the positioning rib 122. One side of the positioning rib 122 is connected to a reinforcing column 124. Two opposite outer sidewalls of the assembly protrusion 21 have a plurality of engaging ribs 21 corresponding to the engaging grooves 121, and another two outer sidewalls have at least one positioning notch 213 and two positioning nodes 214 on each side of the positioning notch 213. The positioning notch is configured for engaging with the positioning rib 122, and the positioning node 214 is configured for engaging with the positioning groove 123. Therefore, the assembly protrusion 21 can fit into the assembly space 12 by a straight up and down movement.
The lifting mechanism 30 has a lower base 31, a top base 32 and two X-shaped support frames 33. Two opposite sidewalls of the lower base 31 have two parallel lower guiding slots 311, two opposite sidewalls of the top base 32 have two parallel upper guiding slots 321, and the two X-shaped support frames 33 are connected via a center link rod 331, two lower link rods 332, and the two upper link rods 333. Two ends of one of lower link rods 332 are respectively secured onto one end of the two lower guiding slots 311 of the lower base 31, and two ends of another lower link rod 332 are configured to be connected to the lower base 31 by sliding along the two lower guiding slots 311. Furthermore, two ends of one of the upper link rods 333 are respectively secured onto one end of the two upper guiding slots 321 of the top base 32, two ends of another upper link rod 333 are configured to be connected to the top base 32 by sliding along the two upper guiding slots 321. In addition, a control screw 34 is installed between the two upper link rods 333 for controlling movement of the lifting mechanism 30.
Also, the control screw 30 is configured to be operated manually or electrically.
Additionally, an end of the control screw 34 has a knob 341, another end of the lower member 10 has a through slot 13 connected to the assembly space 12, one sidewall of the accepting space 211 has a through groove 215 connected to the through slot 13. The lower base 31 of the lifting mechanism 30 abuts against the bottom surface of the assembly space 12, while the top base 32 abuts against the top surface of the accepting space 211. The knob 341 of the control screw 34 passes through the through slot 13 and the through groove 215.
Also, the lower member 10 further has a limiting recess 14 around an outer end of the through slot 13, and a hollow tube 23 is disposed in front of the through groove 215 of the upper member 20 for accepting the knob 341 and the control screw 34. The hollow tube 23 is jacketed by an external sleeve 24, an end of the external sleeve 24 has a socket 241 corresponding to the knob 341, and another end has an enlarged end 242 abutting the hollow tube 23. Moreover, when the upper member 20 completely descends the hollow tube 23 is embedded in the limiting recess 14.
When the user's neck bends forward too much, the front edges of the upper and lower cervical vertebrae become to close to each other, which not only makes the C-shaped arc of the cervical vertebrae smaller (that is, the entire cervical vertebrae becomes straighter), but also causes the semi-fluid (nucleus pulposus) in the intervertebral disc between the upper and lower cervical vertebrae pushes back to the tight posterior annular fiber, and finally causes the posterior protrusion of the posterior annular fiber, which compresses the adjacent cervical nerve, causing shoulder and neck, even upper arm pain and soreness. Therefore, as long as the front edges of the upper and lower cervical vertebrae are separated, the straightened C-shaped arc of the cervical vertebrae returns to the original C-shape and the posterior annular fibers will not be affected and the herniation of the intervertebral disc will naturally subside. On the other hand, the two cervical vertebrae that have problems must also be the tender points of the cervical vertebrae. Therefore, by using the neck supporting section 111 of the functional pillow to directly compress the pain points, and it can make the upper and lower cervical vertebrae to be separated to achieve immediate relief of cervical pain.
Therefore, when the user rests on the adjustable pillow of the present invention, please refer to
In addition, due to the long-term use of mobile phones with looking down, the upper and lower cervical vertebrae lose the original natural curvature of the cervical vertebrae due to abnormal alignment, resulting in frequent soreness and discomfort in the neck, shoulders, arms, and upper back. The pillow is able to relieve cervical pain, because the neck supporting section 11 is a hard curved plate, it can directly massage and compress the painful part of the neck by using the body's own gravity weight when lying down, so that the abnormal cervical spine can be aligned, and it can immediately relieve the pain and discomfort of the cervical spine. In addition, the height of the head supporting section 22 can be adjusted through the lifting mechanism 30, so that the painful parts of the cervical spine can be contacted by the head supporting section 22 to moderately compress and massage the pain points of the cervical spine, which gradually improves the pain caused by abnormal alignment of the cervical spine, and also has the correction effect of reproducing the C-shaped curvature of the cervical spine.
With the structure of the above-mentioned specific embodiment, the following benefits can be obtained: the functional pillow of this present invention can be used as a daily pillow, the neck supporting section 11 can provide better support to the neck to achieve the effects of cervical spine health care and natural arc correction and avoid discomfort symptoms caused by abnormal alignment of the cervical spine while maintaining the comfort of use; when the cervical spine is painful and uncomfortable due to improper alignment of the cervical spine caused by improper daily posture, by resting on the adjustable pillow to massage and compress the painful parts of the cervical spine through the neck supporting section 11, and then the lifting mechanism 30 adjusts the height of the upper member 20 in a timely manner, so that the pain points of the cervical spine can be alleviated and improved with moderate, compression and massage force, and further correct the abnormally arranged cervical spine to restore the natural curvature of the cervical spine.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
