Abstract
Description
Technical Field
[0001] This utility model relates to pillows, specifically to a pillow that can automatically adjust its height when the sleeping position changes from side to back, and is a pillow that instantly conforms to the different requirements of pillow height when the sleeping position changes from side to back during sleep. Background Technology
[0002] With the ever-accelerating pace of life, there is a growing emphasis on improving sleep quality at night to alleviate daytime fatigue. This is especially true after the age of thirty, when the flexibility of the neck and shoulder bones, ligaments, and muscles begins to decline, leading to a rise in ailments caused by improper pillow use. Around the age of fifty, neck and shoulder degeneration accelerates, making shoulder problems particularly prevalent. With the introduction of ergonomics and research into the alternating side-lying and supine sleeping positions during sleep, optimal pillow heights for different shoulder widths and heights have been proposed. For example, for a standard height and shoulder width, a pillow height of 12cm is suitable for side-lying and 5cm for supine positions. Furthermore, considering the practical need to turn over approximately 20 times per night to ensure relatively unobstructed blood flow to the blood vessels under the body, the development of an ideal bedding pillow that instantly conforms to the ergonomic changes in side-lying and supine sleeping positions has become a priority.
[0003] Over the years, various technical solutions have been developed to automatically adjust the height of a pillow. However, most solutions involve incorporating a support and lifting mechanism within the pillow core, consisting of rods connected at different angles and elastic elements such as tension and torsion springs. Due to the change in the angle of the support rods and the action of the elastic elements during lifting and lowering, the support force is slightly greater than the weight of the head when lying on one's side, allowing the pillow to remain in a higher position. Conversely, when lowered to a lower position, the support force is significantly less than the weight of the head, allowing the pillow to remain in a lower position. The Ruyi Pillow-ZL93242877.0, developed by the applicant many years ago, is one such example. While it met basic technical requirements and possessed certain functionalities, it did not achieve these goals.
[0004] However, many things happen unconsciously when people use pillows during sleep. For example, when lying on your side, the pillow surface is high, and the support mechanism provides slightly more support than the weight of your head, achieving the ideal balance of being in a high position. If you unconsciously place a hand and upper arm on the pillow surface, the balance is broken, the pillow position drops, and the expected effect is lost. Adjusting the support force slightly greater will directly affect the pillow's ability to smoothly drop to a low position when lying on your back. Similarly, when lying on your back, the pillow surface is low, and the support mechanism provides more support than the weight of your head, achieving the ideal balance of being in a low position. If you unintentionally cough or raise your head, the pillow surface, no longer supporting the weight of your head, will rise to a high position. In this case, the support force in the high position is slightly greater than the weight of your head. If you sleep very soundly, sometimes your head will get stuck in the high position, failing to achieve the ideal balance of being in a low position, affecting the realization of the expected effect, and significantly impacting comfort. Therefore, there are significant technical flaws and gaps in usability.
[0005] After discovering the above problems, the inventor, like other people who are concerned about this technology, has designed a variety of technical solutions and carried out research and development practices over the years. However, he was unable to extricate himself from the single idea of head gravity and support mechanism, and did not achieve the expected results. The technology seemed to have reached a bottleneck. Summary of the Invention
[0006] The purpose of this invention is to overcome the defects of the existing technology and provide a pillow that can automatically adjust its height when the sleeping position changes from side to back.
[0007] The technical solution of this utility model is as follows: a pillow that can automatically adjust its height when alternating between side-lying and supine sleeping positions, comprising a main body, the middle of which is concave, and a last at each of the left and right ends of the main body. A cross-shaped lifting frame is provided at the adjacent last on both sides of the concave left and right sides. The lower end of each cross-shaped lifting frame is mounted on a corresponding lower support rod on the main body, and the upper end of each cross-shaped lifting frame is provided with a corresponding upper support rod. Multiple grooved support rods are provided between the two upper support rods to form a concave depression for placing a small pillow core. Torsion springs are provided next to the two lasts, one end of each torsion spring is connected to the corresponding upper support rod, and the other end of each torsion spring is connected to the corresponding lower support rod. Two bracket plates are hinged to one end of each cross-shaped lifting frame, and bracket support rods are hinged between the two bracket plates at the left and right ends.
[0008] To further ensure that the cross-shaped lifting frames on both sides lift synchronously, parallel rods are connected to the ends of the two cross-shaped lifting frames away from the bracket struts.
[0009] Both ends of the multiple grooved shed poles are fixed to the upper support pole by corresponding shed pole fixing strips.
[0010] Multiple connecting straps are provided on the grooved shed rod.
[0011] To prevent friction noise from occurring when the upper carrying pole comes into contact with the lower carrying pole after it falls, shock-absorbing pads are installed on the two lower carrying poles respectively.
[0012] Pillow cores are installed on the trough-shaped shed poles.
[0013] This utility model, employing the aforementioned technical solution, designs a pillow whose height automatically adjusts to alternating side-lying and supine sleeping positions. It rationally utilizes the pushing force generated by the shoulder against the corresponding position on the side of the pillow during side-lying sleep, and employs a support mechanism connected by a central strut with two "cow legs" to convert the lateral force generated by the shoulder into a multiplied vertical support force. This ensures that the pillow surface remains stably and reliably at a high position during side-lying sleep. Even if the hands or upper arms are inadvertently placed on the pillow surface, it will not cause the pillow to drop to a low position, guaranteeing that the head, cervical spine, and spine are aligned in a straight line parallel to the bed surface during side-lying sleep. This meets the ergonomic requirements for pillow height during side-lying sleep, greatly improving the overall softness and comfort of the pillow. It achieves a "Zhuge Living Pillow" that instantly adapts to the different pillow height requirements during alternating side-lying and supine sleeping positions. Attached Figure Description

Detailed Implementation
[0018] The following description, in conjunction with the accompanying drawings, details a pillow of this invention that automatically adjusts its height to accommodate alternating side-lying and supine sleeping positions.
[0019] Through exploration of existing technologies, the inventors have gradually discovered the existence of a pushing force exerted by the shoulder on the corresponding part of the pillow when lying on one's side. They attempted to introduce this lateral pushing force into the support system to resolve the contradiction between the diverse changes in pillow surface gravity and the singular upward support. After testing various technical solutions, inspired by the "Wooden Ox and Flowing Horse" and the "ox-leg" force-enhancing support, and combining this with the structural characteristics of the support mechanism, they designed a force-enhancing main support mechanism connected by "ox-leg" struts at appropriate support points. This reduced the support force of the original elastic support mechanism by half, significantly improving the overall softness and comfort of the pillow. Through trials and use, the expected results were achieved, the technical bottleneck was overcome, and a truly functional "Zhuge Living Pillow" was realized that instantly adapts to the different pillow height requirements of side-lying posture changes during sleep.
[0020] This utility model relates to a pillow that automatically adjusts its height depending on whether the user is sleeping in a side-lying or supine position. See also... Figures 1 to 3The system includes a pillow body 1 (mother pillow). A lower frame crossbar 12 is located at the front bottom of the body 1, a lower frame middle crossbar 13 is located in the middle of the bottom of the body 1, and a lower frame main support plate 23 is located at the rear of the body 1. The middle of the body 1 is a hollow frame shape. The left and right ends of the body 1 are respectively lasts 7. A front last support plate 9 is located in front of the last 7, and a middle last support plate 14 is located in the middle of the last 7. Cross-shaped lifting frames are respectively provided on the left and right sides of the cavity of the body 1 at adjacent lasts 7. Each cross-shaped lifting frame includes an inner crossbar 18 and an outer crossbar 19 hinged together. The lower end of the outer crossbar 19 is hinged to a lower support rod 10. A pivot located at the lower end of the inner crossbar 18 extends into a groove opened on the lower support rod 10. The lower support rod 10 is located at the corresponding last 7 of the body 1. The upper end of the inner cross support rod 18 is hinged to the upper support rod 8. The pivot at the upper end of the outer cross support rod 19 extends into the sliding groove opened on the upper support rod 8. The inner cross support rod 18 and the outer cross support rod 19, which are hinged together, allow the upper support rod 8 to be raised and lowered. Multiple grooved cantilever rods 6 are provided between the left and right upper support rods 8. If the body 1 is wide, multiple straight cantilever rods 4 can also be provided between the rear ends of the left and right upper support rods 8. The multiple grooved cantilever rods 6 and the multiple straight cantilever rods 4 are pressed against the corresponding upper support rods 8 by the corresponding cantilever rod fixing strips 5. Torsion springs 15 are respectively provided in the two end heads 7. One end of each torsion spring 15 is connected to the corresponding upper support rod 8, and the other end of each torsion spring 15 is connected to the corresponding lower support rod 10. The function of the torsion springs 15 is to apply elastic tension to the cross-shaped lifting frame after it is raised. At the front end of the main body 1, the upper end of the inner cross support rod 18 of each cross-shaped lifting frame is hinged to the upper support plate 16 of the bracket, and the lower end of the outer cross support rod 19 of each cross-shaped lifting frame at the front end of the main body 1 is hinged to the lower support plate 17 of the bracket. The other end of the upper support plate 16 of the bracket is hinged to the other end of the lower support plate 17 of the bracket. The upper support plate 16 of the bracket and the lower support plate 17 of the bracket are connected to the bracket struts 11 at the hinge points on the left and right sides. The lifting and lowering of the cross-shaped lifting frame can move the bracket struts 11 into or out of the main body 1.
[0021] To further ensure the synchronous lifting of the cross-shaped lifting frames on both sides, this utility model has an upper parallel rod 21 connected between the upper ends of the two outer cross support rods 19 and a lower parallel rod 22 connected between the lower ends of the two inner cross support rods 18. Due to the linkage between the upper parallel rod 21 and the lower parallel rod 22, the cross-shaped lifting frames on both sides lift synchronously and move in a coordinated manner.
[0022] This invention features multiple connecting straps 3 on multiple grooved canopy poles 6 and multiple straight canopy poles 4, thus improving the stability of the multiple grooved canopy poles 6 and multiple straight canopy poles 4. This invention also features a pillow core 2 (sub-pillow) on the grooved canopy pole 6.
[0023] When the pillow surface descends to the lowest position, the upper support 8 will come into contact with the lower support 10 after it falls. In order to prevent friction noise from occurring when the upper support 8 comes into contact with the lower support 10 after it falls, this utility model provides anti-vibration pads 24 on the two lower support 10 respectively.
[0024] When in use, when sleeping on your back, the shoulder's pushing force on the side of the pillow disappears due to the change in sleeping position. At this time, the only support for the pillow surface is the upward support force of the torsion springs 15 at both ends. Since the pillow position is high when lying on your back, there is a strong double-cog leg force-increasing mechanism. The support force of the torsion springs 15 at both ends is only designed to be half of the head's weight. The torsion springs 15 cannot support the head on the high pillow position on their own. Instead, the head can only slowly fall to the low position as the head and pillow surface descend, which plays a certain role in elastic cushioning. At this point, the double cow-leg support boards (upper cow-leg support board 16 and lower cow-leg support board 17) lose the support from the shoulders of the cow-leg support rod 11, causing the pillow surface to drop. Like a cow kneeling, this pushes the cow-leg support rod 11 forward and downward, stopping at the empty position below the neck when lying on the side. This helps to support the neck. At the same time, the downward vertical force exerted by the neck on the cow-leg support rod 11 not only helps to keep the pillow surface stable in a low position when lying on the back through the lateral transmission of the double cow-leg support boards, but also prevents the pillow surface from rising rapidly to a high position due to unintentional slight head movement, thus ensuring the beneficial effect of ergonomic low position comfort and stability when lying on the back.
[0025] When changing from supine to lateral position, as the upper body moves towards the center line of the supine bed, the head and neck naturally lift off the pillow surface. The downward pressure of the head on the pillow surface and the neck on the grooved support rod 6 disappears. The torsion springs 15 at both ends lift the pillow surface back to its original high position. The middle support rod mechanism of the double-leg support plate also returns to the high support state. The completion of the side-lying turning and movement, the shoulder on the side of the pillow also transmits a small horizontal pushing force to the cross-shaped lifting frame at both ends through the corresponding position of the double-leg support rod 11. Through the conversion and amplification of the force of the double-leg joint, the pillow surface is stabilized at the comfortable height position indicated by ergonomics when lying on the side. Even if you lift your head to apply pressure or place both upper arms and head on the pillow at the same time, the height cannot be changed. Stability, reliability and comfort are greatly guaranteed.
