Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a pillow. Background Art

[0002] Existing pillows consist of a pillow core and a pillowcase that wraps the core. The core is filled with a filling component. Because the filling component is made of soft fiber material, the pillow core provides only limited support and cannot provide multiple comfort levels. Furthermore, the pillow core is too soft, resulting in reduced comfort and a poor user experience. Furthermore, existing pillow cores only provide vertical support for the user's head and neck, resulting in a limited functionality. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model provides a pillow in which a vertically stacked upper core plate and a lower core plate are arranged in the pillow core, which can not only provide the user with multiple body-sensing vertical support, but also utilize the upper core plate to generate horizontal traction, thereby improving the comfort of use.

[0004] The present invention is implemented as follows: a pillow comprising a pillow core and a pillowcase encasing the pillow core, wherein the pillow core comprises a vertically stacked upper core plate and a lower core plate, wherein the upper core plate has a lower hardness than the lower core plate, so that the pillow core forms two levels of support with differentiated strength when subjected to vertical compression and deformation. The vertically stacked upper and lower core plates are disposed within the pillow core, each having different hardnesses, thereby providing the user with multiple levels of vertical support and enhancing user comfort by utilizing the upper core plate to generate horizontal traction.

[0005] Preferably, the bottom surface of the upper core plate matches the top surface of the lower core plate, ensuring a tight fit between the upper and lower core plates. This ensures effective force transfer and ensures that each area of ​​the upper pillow core receives support from the corresponding area of ​​the lower pillow core, ensuring that each area of ​​the upper core plate's top surface provides a consistent feel.

[0006] Preferably, the bottom surface of the upper core plate and the top surface of the lower core plate are bonded and fixed so that the upper core plate and the lower core plate have differentiated hardness. The upper core plate and the lower core plate are independently processed and bonded and fixed, which is convenient for setting differentiated hardness of the upper core plate and the lower core plate and improving processing convenience. It also ensures that the relative position is fixed through bonding and fixing, providing users with a double support feeling.

[0007] Preferably, the upper and lower core plates are integrally formed and have differentiated densities, so that the upper and lower core plates have differentiated hardnesses. Differentiated hardnesses are obtained by setting differentiated densities, thereby providing the user with a dual support sensation.

[0008] Preferably, the upper and lower core panels are stacked vertically and enclosed by a central inner sleeve to limit force offset between the upper and lower core panels. The central inner sleeve secures the upper and lower core panels relative to each other, providing a dual support experience for the user.

[0009] Preferably, an outer opening for installing the pillow core is provided at the edge of the pillowcase, and an inner opening for installing and removing the upper and lower core plates is provided at the edge of the central inner case. The outer and inner openings are overlapped and sewn shut. The pillow core is inserted into the pillowcase through the outer opening, and the overlapped upper and lower core plates are inserted into the central inner case through the inner opening. The outer and inner openings are overlapped and uniformly sewn shut. This not only seals the outer and inner openings, but also effectively simplifies the processing steps and improves processing efficiency.

[0010] Preferably, the upper core plate includes a first support portion and a second support portion that are separated into front and back parts. The first support portion is arranged higher than the second support portion. The top surface of the first support portion forms a first support surface, and the top surface of the second support portion forms a second support surface. The first support surface and the second support surface are connected by a recessed connecting surface. The supported object slides from the first support portion to the second support portion by its own weight and generates a horizontal traction force. The upper core plate includes a first support portion and a second support portion with a height difference. The user's head can slide from the first support portion to the second support portion along the connecting surface by its own weight and generate a traction force for horizontally stretching the neck, and ensure that the user's head and neck can be supported by the second support portion and the first support portion respectively, effectively improving the comfort of use. The first support surface and the second support surface can support the neck and the top respectively.

[0011] Preferably, the front and rear edges of the upper core plate are recessed to form neck support grooves. The groove walls conform to the surface of the user's neck, enhancing neck support comfort. The neck support grooves on both the front and rear edges of the upper core plate allow the pillow to be used in multiple orientations, enhancing the user experience.

[0012] Preferably, the first support surface and the second support surface are partially upwardly raised arc surfaces, which not only limit the corresponding parts of the user, but also effectively improve the fit, thereby enhancing the effective support.

[0013] Preferably, the pillow core includes a lower filling layer disposed below the lower core plate and an upper filling layer disposed above the upper core plate. The bottom surface of the upper filling layer and the top surface of the upper core plate, as well as the top surface of the lower filling layer and the bottom surface of the lower core plate, are matched and fitted together, so that when the pillow core is vertically compressed and deformed, it forms multi-level support with differentiated strength. The upper and lower filling layers vertically clamp the upper and lower core plates. The upper filling layer acts as a buffer, using its own deformation to fill the gap between the upper core plate and the user's body, providing the user with a multi-level support experience. It also improves user comfort by reducing the foreign body sensation caused by the upper core plate.

[0014] Preferably, the lower filling layer comprises multiple lower sections of varying thickness and a lower inner sleeve that wraps and secures the lower sections. The bottom surfaces of the lower sections are arranged at the same height and horizontally, ensuring that the top surface of the lower filling layer matches and fits the bottom surface of the lower core plate. The differentiated thickness of each lower section ensures a consistent fit between the top surface of the lower filling layer and the bottom surface of the lower core plate, prevents unevenness on the pillow core bottom surface due to shifting of filling material between sections, and ensures that the upper and lower core plates maintain their pre-set positions. The lower inner sleeve wraps and secures the lower sections, ensuring that the relative positions of the lower sections are fixed.

[0015] Preferably, the upper filling layer comprises multiple upper sections of varying thickness and an upper inner sleeve that wraps and secures the upper sections. The upper sections are arranged at the same height and arranged horizontally, ensuring that the bottom surface of the upper filling layer aligns with the top surface of the upper core plate. The differentiated thickness of each upper section ensures a consistent fit between the bottom surface of the upper filling layer and the top surface of the upper core plate, while also preventing unevenness on the pillow core surface due to shifting of filling material between the upper sections. The upper inner sleeve wraps and secures the upper sections, ensuring that the upper sections are fixed relative to each other.

[0016] The beneficial effects of the present invention are as follows: an upper core plate and a lower core plate stacked vertically are arranged in the pillow core, and the upper core plate and the lower core plate have different hardnesses, which can not only provide the user with multiple body-sensing vertical support, but also utilize the upper core plate to generate horizontal traction, thereby improving the comfort of use.

DETAILED DESCRIPTION

[0024] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0025] like Figure 1 and 2 A pillow shown includes a pillow core and a pillowcase 1 that wraps the core. The pillow core includes a vertically stacked upper core plate 2 and a lower core plate 3. The upper core plate 2 has a lower hardness than the lower core plate 3, so that the pillow core forms two levels of support with differentiated strength when subjected to vertical compression and deformation. The vertically stacked upper and lower core plates 2, 3, are arranged within the pillow core. The upper and lower core plates 2, 3 have different hardnesses, providing the user with multiple levels of vertical support and enhancing comfort by utilizing the upper core plate 2 to generate horizontal traction.

[0026] In actual operation, the bottom surface of the upper core plate 2 matches the top surface of the lower core plate 3, so that the upper core plate 2 and the lower core plate 3 are tightly stacked. The upper core plate 2 is placed on the lower core plate 3, and the vertical projections of the two overlap, ensuring that each area of ​​the upper core plate 2 is supported by the corresponding area of ​​the lower core plate 3, providing a variety of support for the user's head and neck.

[0027] In actual operation, the hardness of the upper core plate 2 is less than that of the lower core plate 3, making the upper core plate 2 easier to deform, ensuring that the upper core plate 2 can fit the surface of the user's head and neck through deformation, and can also transfer the gravity of the user's head and neck downward to the lower core plate 3, ensuring that the lower core plate 3 and the upper core plate 2 can provide the user with differentiated support feeling, thereby improving support comfort.

[0028] In actual operation, the upper core plate 2 and the lower core plate 3 are independently arranged, which is convenient for forming differentiated hardness through independent processing, and also ensures that the relative position is fixed by stacking and fixing each other, providing users with a stable and reliable double support experience.

[0029] During production, the upper core plate 2 and the lower core plate 3 are integrally formed and have differentiated densities. The upper core plate 2 and the lower core plate 3 are integrally formed by polyurethane foaming, so that the upper core plate 2 and the lower core plate 3 have differentiated hardness. In addition, the upper core plate 2 and the lower core plate 3 can also be formed by 3D printing of materials, and a predetermined hardness is obtained by setting differentiated densities, which should also be considered as a specific implementation method of this embodiment.

[0030] During assembly, the upper core plate 2 and the lower core plate 3 can be fixedly connected by various methods, including but not limited to bonding, wrapping with an intermediate inner sleeve 4, etc., to limit the force offset between the upper core plate 2 and the lower core plate 3, all of which should be considered as specific implementation methods of this embodiment. Specifically, the bottom surface of the upper core plate 2 and the top surface of the lower core plate 3 are fixedly connected by bonding.

[0031] In actual operation, the upper core plate 2 includes a first support portion 7 and a second support portion 8 (such as Figure 3 As shown), the first support portion 7 is higher than the second support portion 8, the top surface of the first support portion 7 forms a first support surface, the top surface of the second support portion 8 forms a second support surface, and the first support surface and the second support surface are connected by a concave connecting surface 9 (as shown). Figure 4 As shown), the supported object utilizes its own gravity to slide from the first support portion 7 to the second support portion 8 and generates a horizontal traction force. A recessed connecting surface 9 is provided between the first supporting surface of the first support portion 7 and the second supporting surface of the second support portion 8. The first supporting surface is higher than the second supporting surface and is connected by a smooth connecting surface 9. When in use, the user's head and neck lie on the pillow. The head and neck will first contact the filling component. The filling component responds to the weight of the user's head and neck through its own vertical compression deformation, and utilizes the upper core plate 2 and the lower core plate 3 to provide vertical support force to the user's head and neck, so that the user's head and neck can obtain multiple vertical forces, ensuring that the user's head and neck can be supported by the upper core plate 2 and the lower core plate 3, and also ensuring that the user's head and neck can fit with the compression-deformed filling component. By increasing the contact area between the user and the pillow, the weight is dispersed, thereby improving the support comfort and preventing discomfort caused by localized concentrated force on the head and neck. In addition, when the user's head is vertically overlapped on the first support surface or the connecting surface 9, the head's own gravity will drive it to slide along the connecting surface 9 to the second support surface. The inclined connecting surface 9 is used to convert the head's gravity into horizontal traction, stretching the user's neck, thereby improving the user experience by increasing the function of the pillow.

[0032] In actual operation, the front and rear edges of the middle portion of the upper core plate 2 are both recessed to form a neck support groove 10 (such as Figure 5The neck support groove 10 is formed by a depression and matches the surface contour of the neck. When in use, the neck is embedded in the neck support groove 10, which improves support comfort by increasing the contact area. The two neck support grooves 10 are located at the front and rear edges of the upper core plate 2, allowing the pillow to be rotated front and back, increasing the variety of usage options.

[0033] In actual operation, the first support surface and the second support surface are partially curved surfaces that bulge upward, which effectively improves the fit between the top surface of the upper core plate 2 and the surface of the user's head and neck.

[0034] In actual operation, the pillow core includes a lower filling layer 11 arranged below the lower core plate 3 and an upper filling layer 12 arranged above the upper core plate 2. The bottom surface of the upper filling layer 12 and the top surface of the upper core plate 2, and the top surface of the lower filling layer 11 and the bottom surface of the lower core plate 3 are matched and fitted, so that the pillow core forms a multi-level support with differentiated strength when it is vertically compressed and deformed. The upper filling layer 12 is arranged above the upper core plate 2 to play a buffering role, preventing the user's head and neck from directly contacting the top surface of the upper core plate 2, effectively improving contact comfort. The lower filling layer 11 supports the lower core plate 3 and the upper core plate 2, ensuring that the upper core plate 2 always maintains a posture in which the first support part 7 is higher than the second support part 8, thereby providing comfortable support and appropriate traction for the user.

[0035] In actual operation, the upper filling layer 12 and the lower filling layer 11 vertically clamp the upper core plate 2 and the lower core plate 3 and are wrapped and limited by the pillowcase 1. The outer opening 5 for installing the pillow core is provided at the edge of the pillowcase 1 (such as Figure 6 As shown), the edge of the central inner sleeve 4 is provided with an inner opening 6 for disassembly and assembly of the upper core plate 2 and the lower core plate 3, and the outer opening 5 and the inner opening 6 are overlapped and sealed by sewing.

[0036] In actual operation, the lower filling layer 11 includes a plurality of lower partitions with differentiated thicknesses and a lower inner sleeve that wraps and fixes the lower partitions. The bottom surfaces of the lower partitions are arranged at the same height and arranged horizontally, so that the top surface of the lower filling layer 11 matches and fits with the bottom surface of the lower core plate 3. The upper filling layer 12 includes a plurality of upper partitions with differentiated thicknesses and an upper inner sleeve that wraps and fixes the upper partitions. The top surfaces of the upper partitions are arranged at the same height and arranged horizontally, so that the bottom surface of the upper filling layer 12 matches and fits with the top surface of the upper core plate 2. Both the upper filling layer 12 and the lower filling layer 11 have a partitioned structure. The fillings in each partition do not flow into each other, ensuring that the thickness of each partition remains constant, thereby ensuring that the thickness of each area of ​​the pillow body remains consistent, improving support comfort and reliability. The fillings in the upper filling layer 12 and the lower filling layer 11 can be fluffy down or fiber materials, which effectively improves user comfort and should be considered as specific embodiments of the present invention.
