Description

Technical Field

[0001] This utility model relates to bedding, specifically a portable cervical pillow. Background Technology

[0002] In modern society, with changes in people's lifestyles, bad habits such as prolonged desk work and looking down at electronic devices are becoming increasingly common, making cervical spine problems a health hazard that plagues many people. As an important part of the human spine, the cervical spine plays a crucial role in supporting the weight of the head and ensuring flexible neck movement. Its normal physiological curvature is essential for maintaining the biomechanical balance of the neck and even the entire spine.

[0003] Cervical pillows have emerged to address this need, meticulously designed based on the anatomical characteristics and physiological curvature of the human cervical spine. A high-quality cervical pillow's height and curvature precisely match the natural shape of the cervical spine. When the user lies on it during sleep, it provides just the right amount of support for the cervical spine, effectively distributing pressure on the head and helping the cervical spine maintain its normal physiological position. This slows down the degenerative process of the cervical spine caused by accumulated poor posture, inhibits the occurrence and worsening of conditions such as changes in the physiological curvature of the cervical spine, and provides a certain degree of relief for patients with cervical spondylosis, helping them improve sleep quality and reduce discomfort such as neck pain and stiffness.

[0004] However, with people traveling frequently these days, especially for business trips or leisure travel, accommodation is mostly found in hotels. But the hotel industry generally follows a standardized room configuration model, typically providing only regular flat pillows as bedding. These pillows are not specially designed for cervical spine health and cannot meet the needs of people accustomed to using cervical pillows. This puts travelers who normally rely on cervical pillows for good sleep and relief from neck discomfort in a dilemma when checking into a hotel: using the hotel's regular pillows doesn't provide effective support for the cervical spine during sleep, making it difficult to enter deep sleep and potentially worsening cervical problems during the trip; bringing their own cervical pillows from home presents numerous inconveniences.

[0005] Existing cervical pillows, in order to achieve good support in the home environment, often use relatively thick and hard internal filling structures, resulting in a large overall volume and a lack of portability design considerations. Their large size takes up a lot of valuable space in suitcases, which is undoubtedly a heavy burden for modern people who pursue lightweight travel; moreover, their irregular shape is also prone to being squeezed and deformed during transportation, affecting their performance.

[0006] Meanwhile, U-shaped pillows, popular in the market for their portability and ability to wrap around the neck, have become a common sleep aid during long journeys, favored by many travelers. However, to balance folding and storage with wearing comfort, U-shaped pillows are often filled with soft materials such as sponge and down, whose support strength is far inferior to that of professional cervical pillows. For patients with cervical spondylosis, these soft U-shaped pillows cannot form a stable and strong support surface on the back of the neck, making it difficult to maintain the correct posture of the cervical spine. Prolonged wear may even exacerbate cervical fatigue and damage, failing to truly meet their urgent need for cervical spine care during travel. Utility Model Content

[0007] In view of the above-mentioned defects or one of the defects in the existing technology, this utility model aims to provide a new type of cervical pillow product that can not only meet the physiological needs of the cervical spine and effectively protect cervical spine health, but also has excellent portability and can be easily used by people in mobile scenarios such as travel and business trips, so as to fill this market gap and provide a comprehensive and comfortable sleep solution for the majority of people suffering from cervical spine problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A portable cervical pillow includes a left support body, a right support body, and several bamboo strips of the same size. The bamboo strips are connected by at least two elastic bands near their ends, so that the sides of two adjacent bamboo strips are close to each other and the whole bamboo strips are gathered into a cylindrical shape. The circumference of the elastic bands in their natural state is less than the circumference of the cylindrical shape formed by the bamboo strips. The insertion parts of the left and right support bodies are respectively inserted into the two ends of the cylindrical shape formed by the bamboo strips. The circumference of the insertion part is greater than the circumference of the cylindrical shape formed by the bamboo strips in their natural state.

[0010] Furthermore, several bamboo strips serve as warp and at least two rubber band loops serve as weft, with the weft interlacing with the warp in an inner-outer pattern.

[0011] Furthermore, two adjacent rubber band loops are staggered inside and outside at the same bamboo strip.

[0012] Furthermore, the bamboo strips are 500mm long, 20mm wide, and 8mm thick, and there are 14 of them.

[0013] Furthermore, the insertion part of the left support is barrel-shaped, with its outer end extending outward to form a left-hand flange that abuts against the left end face of several bamboo strips; the insertion part of the right support is also barrel-shaped, with its outer end extending outward to form a right-hand flange that abuts against the right end face of several bamboo strips; the insertion parts of the left and right supports have the same shape and the same circumference.

[0014] Furthermore, the outline of the insertion part at any point is a bun shape formed by a superior arc and a straight line; the bottom of the insertion part transitions to the barrel wall with a rounded arc.

[0015] Furthermore, the length of the insertion part is 80mm, and the diameter of the superior arc is 120mm.

[0016] Furthermore, the left fold edge can be inserted into the right fold edge.

[0017] Furthermore, an iron ring is fixed to the end face of the left flange, and multiple magnets are fixed to the inner end face of the right flange.

[0018] Furthermore, on the lower plane of the insertion part corresponding to the straight outline, two positioning grooves extend outward to accommodate the insertion of both ends of the bamboo strip.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. Like a high-quality cervical pillow meticulously designed based on the anatomical characteristics and physiological curvature of the human cervical spine, this portable cervical pillow precisely conforms to the natural shape of the cervical spine during use. Through a cylindrical structure formed by several bamboo strips and the coordinated action of the left and right support bodies, it provides just the right amount of support for the cervical spine, effectively distributing pressure on the head, promoting the cervical spine to maintain its normal physiological position, and thus effectively slowing down the degenerative process of the cervical spine caused by poor daily posture, inhibiting the worsening of symptoms such as changes in the physiological curvature of the cervical spine, effectively relieving symptoms of cervical spondylosis, reducing neck pain, stiffness, and other discomfort, ensuring the user's cervical health, and improving sleep quality.

[0021] 2. The innovative design combining bamboo strips and elastic bands overcomes the drawbacks of traditional cervical pillows, which are thick, bulky, and inconvenient to carry. When not in use, the bamboo strips are connected by elastic bands, allowing for flexible shape adjustment. Furthermore, the circumference of the elastic bands in their natural state is smaller than the circumference of the bamboo strips when bound together, resulting in a more compact overall structure that is easy to store without taking up too much valuable space in your suitcase. At the same time, the regular shape of the bamboo strips and elastic bands, compared to the irregular shape of traditional cervical pillows, makes them less prone to deformation during transportation, ensuring consistent performance with each use, perfectly meeting the modern desire for lightweight travel.

[0022] 3. Filling a market gap, this product not only resolves the issue of ordinary flat pillows in hotels failing to meet cervical health needs, but also overcomes the shortcomings of traditional cervical pillows, such as inconvenience in portability and insufficient support strength of U-shaped pillows, which are inadequate for cervical spine patients. It is a comprehensive and comfortable sleep solution tailored for people suffering from cervical spine problems and frequent travelers. Whether it's a short nap during business trips or a restful night's sleep while traveling, users can enjoy the same comfortable experience as using a professional cervical pillow at home, protecting their cervical spine health anytime, anywhere.

Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] like Figure 1-9 As shown, this portable cervical pillow mainly consists of a left support body 1, a right support body 2, and 14 bamboo strips 3 of the same size.

[0036] During the manufacturing process, the bamboo strips 3 are first pre-treated to ensure uniform size, smooth surface without burrs, and precise settings for parameters such as length, width, and thickness based on the human cervical spine support requirements and portability considerations. For example, the length of bamboo strip 3 can be 500mm, the width 20mm, and the thickness 8mm. Next, 16 elastic band loops 4 are combined with the bamboo strips 3 using a specific weaving method. Specifically, 14 bamboo strips 3 are used as warp, and the 16 elastic band loops 4 are used as weft. The weft loops are interwoven with the warp loops, one inside and one outside, and adjacent elastic band loops 4 are staggered inside and outside the same bamboo strip 3. This weaving operation ensures that the sides of adjacent bamboo strips 3 are closely close together, forming a cylindrical shape. It is important to emphasize that the circumference of the elastic band loops 4 in their natural state is designed to be smaller than the circumference of the cylindrical shape formed by the 14 bamboo strips 3. This ingenious design offers multiple advantages. On the one hand, this lays the groundwork for convenient storage later on; on the other hand, when the left support 1 and right support 2 are inserted into the cylindrical shape formed by 14 bamboo strips 3, the contraction of the elastic band 4 causes the cylindrical shape to exert a continuous wrapping force on the left support 1 and right support 2. This wrapping force ensures that the left and right supports fit tightly against the bamboo strips 3, so that even if the pillow is squeezed or shaken by external forces during use, the left support 1 and right support 2 will not easily fall off, ensuring the stability of the pillow structure and guaranteeing that the user can continuously receive reliable cervical spine support.

[0037] Next, left support 1 and right support 2 are prepared. The insertion part 10 of both is barrel-shaped and has the same shape and circumference. The outer end of the insertion part 10 of the left support 1 extends outward to form a left flange 12, and the outer end of the insertion part 10 of the right support 2 extends outward to form a right flange 22.

[0038] When assembly is required, since the eight elastic bands 4 are pre-woven into the 14 bamboo strips 3, the user only needs to perform a simple operation. Insert the left barrel 11 of the left support body 1 into the left end of the 14 bamboo strips 3, so that the left flange 12 precisely abuts against the left end face of the bamboo strip 3. Then insert the right barrel 21 of the right support body 2 into the right end of the 14 bamboo strips 3, so that the right flange 22 firmly abuts against the right end face of the bamboo strip 3. In this way, the 14 bamboo strips 3 quickly form a neat cylindrical shape. Thus, a portable cervical pillow that can be used is efficiently assembled. When using the pillow, to further improve comfort and hygiene, the user can cover it with a towel, pillowcase, or pajamas according to personal needs and actual scenarios. The soft texture of a towel increases the skin-friendly feel and also has a certain sweat-absorbing function, effectively absorbing sweat that may be produced on the head or neck during sleep and keeping the area dry. A pillowcase serves a dual purpose of decoration and protection, enriching the pillow's appearance while preventing stains from directly getting on it, and making it easy to wash and change daily. Pajamas are usually made of loose and soft materials, creating a familiar and cozy sleeping atmosphere when placed on the pillow, allowing for quick relaxation even in unfamiliar environments (such as staying in a hotel while traveling). The cylindrical shape formed by bamboo strips, along with left and right support bodies, provides solid and reliable support for the cervical spine, effectively distributing head pressure and maintaining the normal physiological position of the cervical spine, thus ensuring cervical spine health during sleep and allowing users to enjoy a comfortable sleep experience.

[0039] When it's time to put away after use, the portability of this invention becomes readily apparent. Users don't need to spend time and effort disassembling the elastic band 4 and the bamboo strip 3; they simply pull the left support 1 from the left end of the bamboo strip 3 and the right support 2 from the right end, then neatly arrange the bamboo strip 3, left support 1, and right support 2 together. Thanks to the aforementioned structural design, the bamboo strip 3, bound by the elastic band 4, can naturally converge and compress according to the circumference of the elastic band 4, resulting in a more regular and compact storage form. The insertion parts 10 of the left and right supports and the folded edge design also contribute to portability; their regular shape makes them easy to organize and arrange after disassembly, and together with the compressed bamboo strip 3, they can be easily placed in suitcases or other spaces with limited space for carrying or storage. When needed again, following the previous assembly steps, the pillow can be quickly reassembled, ready to begin another round of comfortable sleep.

[0040] Through the meticulous design and ingenious coordination of the above-mentioned components, this utility model successfully achieves the dual goals of both meeting the physiological needs of the cervical spine and possessing excellent portability, providing an ideal sleep aid for those suffering from cervical spine problems during travel and effectively filling a market gap.

[0041] In another preferred embodiment, the bamboo strip 3 is 500mm long, 20mm wide, and 8mm thick. The 500mm length ensures sufficient support for the cervical spine and part of the head after being assembled into a cylindrical cervical pillow. This length covers the main part of the cervical spine, providing ample support and allowing for complete and continuous support during sleep, helping to maintain the normal physiological curvature of the cervical spine. The 500mm length is relatively moderate while maintaining the pillow's function, avoiding excessive length that would make it difficult to pack in luggage or other travel gear. Furthermore, when disassembled from other components, the bamboo strips can be neatly arranged, occupying a reasonable amount of space and facilitating portability. The 20mm width prevents the bamboo strips from being too narrow after assembly, thus avoiding insufficient support or localized pressure on the cervical spine. This width ensures stable support while distributing pressure on the head, preventing pressure concentration at a single point or in a small area, thus improving user comfort. The 8mm thickness helps the bamboo strips provide sufficient support strength. This thickness ensures the bamboo strips possess sufficient rigidity to prevent easy deformation under the weight of the head when supporting the cervical spine, effectively maintaining its correct position and positively impacting cervical spine pressure and preventing deformation. The 20mm width and 8mm thickness make the bamboo strips easy to handle during assembly, avoiding difficulties caused by excessive thickness or width. Users can easily insert the left and right supports into both ends of the bamboo strips to assemble the pillow quickly and easily. These dimensional parameters work together to ensure good overall stability after the bamboo strips are connected by elastic bands to form a cylindrical structure. The width and thickness provide the bamboo strips' inherent strength, while the length ensures structural continuity. This allows the pillow to maintain a stable shape under head pressure, preventing it from easily falling apart or deforming, thus guaranteeing product quality and lifespan.

[0042] In another preferred embodiment, the outline of the insertion part 10 at any point is a dome shape formed by an arc and a straight line; the bottom of the insertion part 10 transitions to the wall of the dome with a rounded transition. The straight line segment in the dome-shaped outline plays a unique role. The plane it forms has a practical placement stability function. When the pillow is placed on the bed, this plane has a large contact area with the bed surface and fits tightly, effectively resisting the tendency to roll due to external forces or its own shape characteristics. In daily use scenarios, such as turning over or adjusting sleeping position during sleep, or storing the pillow when not in use, the pillow can maintain a relatively fixed position with the help of this plane, and is not prone to displacement or rolling, providing users with continuous convenient and stable cervical spine support. The rounded transition design eliminates right angles or sharp edges between the bottom and the wall of the dome. When inserting the left dome 11 and the right dome 21 into the bamboo strip 3, this smooth transition makes it easier for the dome to enter the space between the bamboo strips, reducing friction and jamming during insertion. Compared with shapes with sharp edges, there is no situation where the bamboo strip is jammed due to sharp edges, causing difficulty in insertion. The rounded shape acts as a guide, helping users insert the tube along the axial direction of the bamboo strips more accurately, reducing the difficulty of insertion and making the assembly process smoother and more efficient. The absence of sharp edges effectively prevents scratches, splits, or other damage to the bamboo strips during insertion. Maintaining the integrity of the bamboo strips is crucial for ensuring the pillow's lifespan and performance, as damaged bamboo strips can affect the pillow's support and overall stability.

[0043] In another preferred embodiment, the left folding edge 12 can be inserted into the right folding edge 22. By inserting the left folding edge 12 into the right folding edge 22, the components originally intended as a cervical pillow can be cleverly combined to form a relatively enclosed space, transforming into a toiletries storage box, thereby increasing the product's functionality. In scenarios such as travel, people often need a convenient container to store toiletries such as towels and toothbrushes. This deformable design perfectly meets this need, eliminating the need to carry a separate storage container and saving luggage space. It provides a centralized space for small toiletries such as towels and toothbrushes, preventing these items from being scattered in suitcases, making it easier for users to organize and find them, and making travel items more organized and orderly, improving the convenience and efficiency of storage. By modifying the pillow's components to form a storage box, the value of each component is fully utilized, achieving multiple uses for one item, maximizing the use of the space occupied by the product, making the entire travel gear more compact and reasonable, and meeting people's needs for lightweight travel and efficient space utilization. The structure of the storage box can protect items such as towels and toiletries placed inside, preventing them from being squeezed or bumped by external forces, reducing the possibility of damage to the items, and ensuring that these toiletries can remain intact and usable at any time during the trip.

[0044] In another preferred embodiment, a ring 13 is fixed to the end face of the left flange 12, and multiple magnets 23 are fixed to the inner end face of the right flange 22. The cooperation of the ring 13 and the magnets 23 makes the connection between the left flange 12 and the right flange 22 more secure. Compared with a simple insertion connection, this magnetic connection provides additional attraction, allowing the box to remain closed better when used as a toiletry storage box, effectively preventing accidental opening and avoiding the falling out of items such as towels and toothbrushes. This connection method is convenient for users. When it is necessary to open the storage box to retrieve items, simply apply appropriate force to separate the left flange 12 and the right flange 22; when closing the storage box, the ring 13 and the magnets 23 will automatically attract each other, eliminating the need for complex alignment or fixing operations, making it easier and more efficient to use. Compared with some mechanical buckles or other connection methods, the magnetic connection does not suffer from mechanical wear due to frequent opening and closing. This helps extend the product's lifespan and ensures that the connection between the left and right folding edges 12 and 22 remains intact during long-term use, enabling the storage box to function stably and continuously.

[0045] In another preferred embodiment, at least one positioning plate 14 extends outward from the lower plane of the left barrel 11 and the right barrel 21, which can be inserted between the same two adjacent bamboo strips 3. During the insertion of the left barrel 11 and the right barrel 21 into the bamboo strips 3, the positioning plate 14 provides precise positioning. This allows the user to more easily align the barrels with the bamboo strips, determine the insertion position, reduce the time spent on trial and error during assembly, and make the assembly operation more efficient and convenient. By inserting between adjacent bamboo strips 3, the positioning plate 14 helps the left barrel 11 and the right barrel 21 to be in the correct position within the bamboo strip structure. This helps ensure the structural stability of the entire cervical pillow after assembly, making the connection between the bamboo strips, the left support body, and the right support body tighter and more reasonable, and preventing the pillow's support effect from being affected by component misalignment during use.

[0046] In another preferred embodiment, the length of the insertion part 10 is 80mm, and the diameter of the curved section is 120mm. From the perspective of conforming to the cervical spine's physiology, a curved section diameter of 120mm can accurately simulate the normal physiological curvature range of the human cervical spine. When the user places their head on the pillow, this size of curved section can closely conform to the curved part of the cervical spine, providing just the right amount of support and preventing the cervical spine from being unsupported or excessively compressed. This effectively maintains the natural shape of the cervical spine and helps relieve cervical spine pressure caused by accumulated poor posture in daily life, which is of positive significance for the prevention and improvement of cervical spine diseases. Regarding structural stability, the 80mm insertion part length is also ingeniously designed. On the one hand, this length ensures that when the insertion part 10 is assembled with the bamboo strip 3, it can penetrate deep into the bamboo strip to reach a suitable depth, forming a stable connection with the bamboo strip. This makes it less likely for the various components to loosen or shift when the entire pillow bears the weight of the head, ensuring the reliability of the pillow structure. On the other hand, this length is perfectly matched with the diameter of the optimal arc, ensuring support and fit while avoiding mechanical imbalance caused by excessive length or length. This further enhances the overall stability of the pillow, ensuring consistent performance over long-term, repeated use. Considering portability, this size combination is also advantageous. The 80mm length is relatively moderate, meeting support requirements without taking up too much space when storing the insertion part 10, making it easy to organize and store with other components. Simultaneously, the regular size design makes the pillow easier to arrange neatly during transportation and carrying, reducing the risk of collisions and compression caused by irregular parts, helping to maintain the pillow's integrity and effectively meeting users' portability requirements in travel scenarios.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
