Description

Technical Field

[0001] This utility model relates to the field of bedding technology, and in particular to a partitioned pillow. Background Technology

[0002] The head is the key piece of bedding for maintaining the natural physiological curvature of the cervical spine during sleep. An ideal pillow should provide differentiated support for different parts of the head and neck to accommodate different sleeping positions such as lying on your back and side.

[0003] Most mainstream pillows on the market are made from a single piece of materials such as latex or memory foam, or filled with down or ordinary foam blocks. However, these traditional structures make it difficult to achieve precise zoning design for support firmness, resulting in significant limitations.

[0004] Specifically, one-piece molded latex or foam pillows have their firmness and density fixed during production, making it impossible to provide a scientifically effective difference in firmness for the neck, which requires strong support, and the head, which requires soft support, on the same pillow surface. Furthermore, everyone's body shape and sleeping posture are different, and their needs for the height and firmness of different areas of the pillow also vary. The homogeneous support characteristics of traditional pillows cannot meet these personalized needs. While filled pillows are initially more malleable, the internal filling is prone to shifting and collapsing during sleep, resulting in an unstable support structure and an inability to provide lasting and effective zoned support.

[0005] Therefore, existing pillows need to be improved to address their inability to provide sustained and effective zoned support.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a zoned pillow that solves the problem that existing pillows cannot provide lasting and effective zoned support.

[0008] To achieve the above objectives, this utility model provides a partitioned pillow, including a top layer, a bottom layer below the top layer, and a plurality of spring support modules located between the two layers.

[0009] The support stiffness is different between two adjacent spring support modules.

[0010] Optional features also include:

[0011] A spring base plate, the bottom surface of which is in contact with the top surface of the bottom pad, and each spring support module includes a plurality of spring cylinders, each spring cylinder being laid flat on the top surface of the spring base plate.

[0012] The bottom of each of the spring cylinders may be magnetically, snap-fit, or threadedly connected to the spring base plate.

[0013] Optionally, the bottom surface of the top layer pad is provided with several transverse limiting grooves parallel to the width of the bed; the upper part of each spring cylinder is inserted into the corresponding transverse limiting groove.

[0014] The spring support module within the two lateral limiting grooves at the optional edge position is a neck area support module;

[0015] There are three spring support modules between the two neck area support modules, including the fossa area support module in the middle and two side sleeping area support modules arranged on both sides of the fossa area support module along the width of the bed.

[0016] The spring wire diameters of the three components—the fossa support module, the side-sleeping support module, and the neck support module—increase sequentially.

[0017] Optionally, the bottom surface of the top layer pad is provided with several longitudinal buffer grooves perpendicular to the transverse limiting grooves at the very center position of the fossa support module; all the spring sleeves of the fossa support module and the spring sleeves of the neck support module that are aligned with the fossa support module along the length of the bed are inserted into the longitudinal buffer grooves.

[0018] The depth of each of the longitudinal buffer grooves is greater than the depth of each of the transverse limiting grooves, such that the distance a from the bottom of the longitudinal buffer groove to the corresponding spring cylinder is greater than the distance b from the bottom of the transverse limiting groove to the corresponding spring cylinder.

[0019] Optionally, the top layer mattress has a horizontal groove parallel to the width of the bed at both the head and foot positions. Each of the top layer edge grooves is provided with a spring support module.

[0020] The bottom layer of the pad has a bottom horizontal groove parallel to the width of the bed at the middle position of the top surface, and at least one spring support module is provided in the bottom horizontal groove.

[0021] Optionally, the spring support module within the transverse groove at the top edge can be a neck area support module;

[0022] The number of spring support modules in the bottom horizontal groove is three, including a fossa support module located in the middle area and two side sleeping area support modules arranged on both sides of the fossa support module.

[0023] The spring wire diameters of the three components—the fossa support module, the side-sleeping support module, and the neck support module—increase sequentially.

[0024] Optionally, the bottom surface of the top layer pad is provided with an intermediate buffer transverse groove located directly above the bottom transverse groove.

[0025] Optionally, the edges of the top layer and the bottom layer can be fixed by adhesive bonding, ultrasonic welding, or thermo-press welding.

[0026] Alternatively, the edges of the top and bottom pads can be connected by a detachable structure using magnetic attraction, snap-fit, or Velcro.

[0027] The beneficial effects of this invention are as follows: It provides a zoned pillow where, when the user uses the pillow, the head and neck contact the top layer of the pillowcase, and spring support modules are located between the top and bottom layers. Due to the different support firmness between adjacent spring support modules, the pillow core provides differentiated support in different areas. For example, a firmer spring support module is used in the neck area to provide strong support, while a softer spring support module is used in the head area to provide gentle support. When the user is lying on their back or side, the spring support modules automatically adjust according to the pressure, adapting to the head and neck curve to achieve zoned support.

[0028] Therefore, the partitioned pillow provided by this utility model can solve the problem that existing pillows cannot provide lasting and effective partitioned support. Attached Figure Description

[0048] This invention provides a partitioned pillow that solves the problem that existing pillows cannot provide lasting and effective partitioned support.

[0049] The partitioned pillow provided in this embodiment includes a top layer, a bottom layer below the top layer, and a plurality of spring support modules between the two layers.

[0050] The support stiffness is different between two adjacent spring support modules.

[0051] When a user uses this zoned pillow, the head and neck contact the top layer of the pillowcase, while the spring support modules are located between the top and bottom layers. Because of the varying firmness between adjacent spring support modules, the pillow core provides differentiated support in different areas. For example, a firmer spring support module is used in the neck area to provide strong support, while a softer spring support module is used in the head area to provide gentle support. When the user is lying on their back or side, the spring support modules automatically adjust according to the pressure, adapting to the curve of the head and neck to achieve zoned support.

[0052] Therefore, the partitioned pillow provided by this utility model can solve the problem that existing pillows cannot provide lasting and effective partitioned support.

[0053] Optionally, both of the pads are made of soft materials such as latex or memory foam.

[0054] Furthermore, the edges of the top layer pad and the bottom layer pad are fixedly joined by adhesive, ultrasonic welding, or hot-press welding.

[0055] Alternatively, the edges of the top and bottom pads can be connected by a detachable structure using magnetic attraction, snap-fit, or Velcro.

[0056] The fixed structure ensures the overall sturdiness and durability of the pillow core; the detachable connection structure greatly facilitates the daily cleaning and maintenance of the pillow core, as well as the personalized adjustment of the internal support module, improving the product's hygiene and user experience.

[0057] The following details two optional arrangement methods for the spring support module.

[0058] (1) Spring support modules are laid out flat on the same layer.

[0059] See Figures 1-3 The partitioned pillow also includes a spring base plate 4. The bottom surface of the spring base plate 4 is in contact with the top surface of the bottom pad 2. Each spring support module 3 includes a plurality of spring cylinders 301, and each spring cylinder 301 is laid flat on the top surface of the spring base plate 4.

[0060] The bottom surface of the spring base plate 4 is in contact with the top surface of the bottom pad 2. Each spring support module 3 contains several spring cylinders 301, and each spring cylinder 301 is laid flat on the top surface of the spring base plate 4. When pressure is applied to the top pad 1, the pressure is transmitted to the spring base plate 4 and the bottom pad 2 through the spring cylinders 301. The spring cylinders 301 provide rebound force according to their hardness. The spring base plate 4 serves as a base platform to ensure that the spring cylinders 301 are evenly distributed.

[0061] Optionally, the bottom of each spring sleeve 301 is magnetically, snap-fit, or threadedly connected to the spring base plate 4. During installation or maintenance, the spring sleeve 301 can be easily disassembled or replaced. This improves the maintainability and customizability of the pillow core, allowing users to adjust the spring support module 3 as needed.

[0062] In this embodiment, the bottom surface of the top layer mattress 1 is provided with several transverse limiting grooves 101 parallel to the width direction of the bed; the upper part of each spring cylinder 301 is inserted into the corresponding transverse limiting groove 101. When the user lies down, the transverse limiting groove 101 constrains the upper part of the spring cylinder 301, preventing the spring cylinder 301 from shifting or tilting along the length direction of the bed, and maintaining the vertical support direction.

[0063] Furthermore, the spring support module 3 within the two lateral limiting grooves 101 at the edge position is a neck area support module 3a;

[0064] There are three spring support modules 3 between the two neck area support modules 3a, including the fossa area support module 3b located in the middle, and two side sleeping area support modules 3c arranged on both sides of the fossa area support module 3b along the width of the bed.

[0065] The spring wire diameters of the three components—the fossa support module 3b, the side-sleeping support module 3c, and the neck support module 3a—increase sequentially.

[0066] When the user lies on their back, the neck area provides firm support for the neck, while the fossa area provides soft support to accommodate the head; when lying on their side, the side-sleeping area provides moderate support. Optionally, the spring wire diameters of the fossa support module 3b, the side-sleeping area support module 3c, and the neck support module 3a are 0.8cm, 1.0cm, and 1.2cm, respectively. With the same spring height, number of coils, waist diameter, and material, a larger wire diameter results in a firmer spring. By using springs with different wire diameters, precise zoned support is achieved: strong support in the neck area to maintain the cervical curvature, soft support in the fossa area to reduce head pressure, and the side-sleeping area to adapt to the side-sleeping position. This design scientifically matches ergonomic needs, improving sleep quality and support effectiveness.

[0067] Optionally, the bottom surface of the top layer pad 1 is provided with a plurality of longitudinal buffer grooves 102 perpendicular to the transverse limiting grooves 101 at the very center position of the fossa region support module 3b; all the spring sleeves 301 of the fossa region support module 3b and the spring sleeves 301 of the neck region support module 3a that are aligned with the fossa region support module 3b along the length of the bed are inserted into the longitudinal buffer grooves 102.

[0068] The depth of each longitudinal buffer groove 102 is greater than the depth of each transverse limiting groove 101, such that the distance 'a' between the bottom of the longitudinal buffer groove 102 and the corresponding spring cylinder 301 is greater than the distance 'b' between the bottom of the transverse limiting groove 101 and the corresponding spring cylinder 301. For example, 'a' is 1cm-1.5cm, and 'b' is 0.5cm-0.8cm.

[0069] The longitudinal buffer groove 102 creates additional cushioning space in the pituitary region and adjacent neck area, which require softer support. This allows the spring sleeves 301 to have a larger initial range of motion in these areas, resulting in better cushioning and a softer feel. At the same time, the larger gap reduces the likelihood and force of direct contact between the top of the spring sleeve 301 and the bottom of the groove, effectively reducing potential noise.

[0070] (2) Spring support modules are arranged in staggered layers.

[0071] See Figure 4 and Figure 5 Specifically, the top layer mattress 1 is provided with a top edge groove 103 parallel to the width of the bed at the position near the head and the position near the foot of the bed, and a spring support module 3 is provided in each top edge groove 103.

[0072] The bottom pad 2 has a bottom horizontal groove 201 parallel to the width of the bed at the middle position of the top surface, and at least one spring support module 3 is provided in the bottom horizontal groove 201.

[0073] The spring support modules 3 are arranged in staggered, layered configurations in the vertical direction. This staggered, layered layout provides another effective way to achieve zoned support, allowing the support modules to be distributed offset in vertical space. This can accommodate more complex support needs and provides greater flexibility and versatility for pillow design.

[0074] Optionally, the spring support module 3 within the top edge transverse groove 103 is a neck area support module 3a;

[0075] The number of spring support modules 3 in the bottom horizontal groove 201 is three, including a fossa support module 3b located in the middle area and two side sleeping area support modules 3c arranged on both sides of the fossa support module 3b.

[0076] The spring wire diameters of the three components—the fossa support module 3b, the side-sleeping support module 3c, and the neck support module 3a—increase sequentially.

[0077] Optionally, the spring wire diameters of the three modules—the fossa support module 3b, the side-sleeping support module 3c, and the neck support module 3a—are 0.8cm, 1.0cm, and 1.2cm, respectively.

[0078] Placing the neck support module 3a, which provides the highest level of support, on the upper front layer allows for direct and efficient neck support. Placing the head support module on the lower layer enables a precise spatial distribution of support functions, achieving the same scientific zoning support effect and enriching the product's form factor.

[0079] Furthermore, the bottom surface of the top layer pad 1 is provided with an intermediate buffer transverse groove 104 located directly above the bottom layer transverse groove 201. The intermediate buffer transverse groove 104 provides additional deformation space for the lower support modules, especially the fossa support module 3b, making its buffering effect more significant, further optimizing the head support experience, and reducing friction and collision noise.

[0080] In summary, the partitioned pillow provided in this embodiment has the following advantages:

[0081] ① By setting adjacent spring support modules 3 with different support hardness, the pillow core achieves zoned differentiated support, which can accurately adapt to the physiological curve of the head and neck.

[0082] ② By setting a transverse limiting groove 101 on the bottom surface of the top layer pad 1, the displacement of the upper part of the spring cylinder 301 is constrained, and the stability of the vertical support is maintained; further setting a longitudinal buffer groove 102 with a larger groove depth provides additional buffer space for key areas such as the fossa area, enhances the soft touch and reduces noise.

[0083] ③ By adopting a staggered layered arrangement of spring support modules 3, the support function is precisely allocated in the vertical space, enriching the product form and adaptability. Furthermore, a middle buffer horizontal groove 104 is set on the bottom surface of the top layer pad 1, providing additional deformation space for the lower support module, optimizing the head support experience and reducing noise.

[0084] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
