Description

Technical Field

[0001] This utility model relates to the field of bedding, and in particular to an adjustable-firm pillow with adjustable zones. Background Technology

[0002] Common pillows use a variety of materials with different levels of firmness, such as memory foam, latex, down, buckwheat, and polyester fiber. Even pillows made from the same material can be further subdivided in height and firmness, making it difficult for consumers to choose the right pillow from the start. Furthermore, consumers may change their preferences for pillow firmness over time. Currently, once the pillow filling is determined, the firmness cannot be changed. This is especially true if the area supporting the neck on the side of the pillow uses the same material as the rest of the pillow, meaning the firmness cannot be adjusted. Long-term use of such pillows may cause discomfort. Using an unsuitable pillow for an extended period can disrupt the normal physiological curvature of the cervical spine, even exacerbating strain and potentially causing or worsening cervical spondylosis. The firmness of the area supporting the neck on the side of the pillow cannot be adjusted. Utility Model Content

[0003] To address the technical problem of existing pillows having no adjustable firmness, which cannot adjust the firmness of the headrest area supporting the neck according to changes in usage needs, and which may affect health or even cause cervical spine diseases with long-term use, this utility model provides a pillow with adjustable firmness in different zones. The pillow can adjust the firmness of the neck support area to adapt to individual consumer needs, help protect the normal physiological curvature of the cervical spine, and avoid the health risks of cervical spine diseases caused or aggravated by sleeping on an uncomfortable pillow for a long time.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A pillow with adjustable zone firmness, comprising a pillow core and a pillowcase, characterized in that the pillow core has adjacent head and neck zones, both extending along the length of the pillow. When the pillow is in use, the head and neck zones respectively support the head and neck, so the firmness of the neck zone can be adjusted. This utility model provides different support effects for the head and neck by setting different zones on the pillow core, and the firmness of the neck zone can be adjusted, providing users with different neck support effects. Users can choose and assemble a pillow suitable for their needs, protecting the normal physiological curvature of the cervical spine and preventing the risk of cervical spine diseases caused or aggravated by sleeping on an uncomfortable pillow for a long time.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the pillowcase is provided with an openable and closable opening structure for taking out and putting in the pillow core. The pillow core is composed of a split head pillow core and several independent neck pillow cores. Each neck pillow core has the same shape and different softness and hardness. Each neck pillow core can be selected and combined on one side of the head pillow core and wrapped and shaped by the pillowcase. The combined neck pillow core and head pillow core form a head section and a neck section respectively. When a neck pillow core is combined with a head pillow core, the remaining neck pillow core is placed outside the pillowcase, or the remaining neck pillow core is placed on the other side of the head pillow core and wrapped and shaped together with the combined head pillow core and neck pillow core by the pillowcase. By disassembling the pillow core into independent head pillow cores and multiple neck pillow cores, each neck pillow core can be used as an independent module in combination with the corresponding head pillow core. Users can select the appropriate firmness of the neck pillow core to combine with the head pillow core according to their needs. The selected two modules combine to form corresponding neck and head sections. The head pillow core containing the head section is not adjustable, while the neck pillow core containing the neck section can be selected and replaced from among the neck pillow cores. After the selected neck and head pillow cores are combined, they are wrapped in a pillowcase to form a pillow. Other unselected neck pillow cores can be placed outside the pillowcase or placed on the other side of the head pillow core and wrapped together with the pillowcase to form a pillow. When changing or replacing the neck pillow core, the opening structure on the pillowcase can be used to remove the original combination of neck pillow cores for replacement. The shape of the pillowcase and the internal cavity space are different in the two cases: when some neck pillow cores are placed outside the pillowcase and when all neck pillow cores are wrapped together in the pillowcase. The pillow core material is usually an elastic material such as sponge or latex, which can be squeezed and deformed to be reinserted into the pillowcase or removed from the pillowcase.

[0006] The neck pillow core has an arc-shaped surface extending in the same direction as its length as a working surface to support the neck. The neck pillow core provides comfortable support for the neck by using its arc-shaped surface as a working surface to support the neck.

[0007] The head pillow core has a recessed mounting platform on one side along its long side for placing the neck pillow core. The mounting platform has two connected mounting surfaces, and the neck pillow core has two mating surfaces that match the two mounting surfaces. When the neck pillow core is placed on the mounting platform, the two mating surfaces are in close contact with the two mounting surfaces, with the curved surface of the neck pillow core facing upwards. The neck pillow core and the head pillow core are flush at their adjacent edges. The mounting platform positions the neck pillow core in conjunction with the head pillow core, and the portion of the head pillow core on the mounting platform supports the neck pillow core. When the neck pillow core and head pillow core are assembled, the two mating surfaces are in close contact with their corresponding mounting surfaces, with the curved surface of the neck pillow core facing upwards. The adjacent edges of the neck pillow core and head pillow core remain flush, preventing unevenness at the assembly points. Unevenness would affect the comfort of the pillow and cause it to press against the pillowcase after being wrapped.

[0008] There are three neck pillow cores of different firmness. The mounting platform has two perpendicularly intersecting mounting surfaces: a horizontal plane and a vertical plane. The mounting platform and the neck pillow cores placed on it are symmetrical in cross-section along the length of the pillow. The head pillow core has a vertical wall on the side away from the mounting platform. Two neck pillow cores are stacked symmetrically against this wall. There are three neck pillow cores in total. One is placed on the mounting platform, and the cross-section of the placed neck pillow core and the mounting platform are symmetrical. The remaining two neck pillow cores are also stacked symmetrically, forming a similar combination to the mounting platform and the neck pillow cores, against the vertical wall of the head pillow core, making the entire combination symmetrical on both sides.

[0009] The pillowcase features an opening structure formed by a zipper. This zipper opening allows for easy opening and closing, facilitating the removal and adjustment of the head and neck pillow inserts. Since most pillow inserts are made of elastic materials, the head and neck pillow inserts can be removed and adjusted even with only one zipper opening.

[0010] The pillowcase has two zippered openings, both extending along the long side of the pillow. These zippers form an adjustment area on the side corresponding to the mounting platform and a replacement area on the side where the neck pillow insert is stacked. The adjustment and replacement zippers allow for faster adjustment and replacement of the neck pillow insert, eliminating the need to remove the head pillow insert from the pillowcase, thus improving the ease of adjustment. Unzipping the replacement area allows for the removal of two stacked spare neck pillow inserts for selection, while unzipping the adjustment area allows for the rearrangement of the neck pillow inserts on the mounting platform. Once the newly selected neck pillow insert is placed on the platform, the replaced and unused neck pillow inserts are returned to their original positions and stacked again.

[0011] The adjustment area zipper is located on the outer edge of the pillowcase, corresponding to the horizontal plane. The replacement area zipper is located on the other side of the pillowcase at the same height as the adjustment area zipper. The placement of both zippers allows for quick removal or insertion of the corresponding neck pillow core, improving ease of use.

[0012] The head pillow and neck pillow are each encased in an inner sleeve. Encasing the head pillow and neck pillow separately in an inner sleeve reduces friction during assembly and disassembly, facilitates operation, and effectively prevents the two pillows from coming into contact with each other and sticking together over time.

[0013] Both the head pillow core and the neck pillow core are made of sponge material. It is very convenient to process head pillow cores and neck pillow cores of different firmness using sponge material, and the cost is easy to control.

[0014] The beneficial technical effects of this utility model are as follows: The pillow core is divided into two sections, providing different support effects for the head and neck respectively. The firmness of the neck section can be adjusted, providing users with different levels of neck support. Users can choose and assemble a pillow that suits their individual needs to protect the normal physiological curvature of the cervical spine and prevent the risk of cervical spine diseases caused or aggravated by sleeping on an uncomfortable pillow for a long time. The pillow core has been changed from a single-piece structure to a combination of a head pillow core and multiple neck pillow cores. Each neck pillow core can be combined with the head pillow core as an independent module and wrapped in a pillowcase to form a pillow. Changing different neck pillow cores allows adjustment of the firmness of the neck section on the pillow. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-3 As shown, Embodiment 1 is an adjustable-firm pillow with adjustable sections, including a pillow core and a pillowcase 1. The pillow core has adjacent head sections 9 and neck sections 10, both of which extend along the length of the pillow. When the pillow is in use, the head sections 9 and neck sections 10 are used to support the head and neck, respectively. The firmness of the neck section 10 can be adjusted by replacing the part containing the neck. The pillowcase 1 has an openable structure for taking out and putting in the pillow core. The pillow core consists of a split head pillow core 4 and several independent neck pillow cores. Each neck pillow core has the same shape but different firmness. The neck pillow core has an arc-shaped surface 5 extending in the same direction as its length as a working surface for supporting the neck. During operation, one of the neck pillow cores can be selected and combined with one side of the head pillow core 4 and wrapped and shaped by the pillowcase 1. The combined neck pillow core and head pillow core 4 form the head section 9 and the neck section 10 respectively. When one neck pillow core is combined with the head pillow core 4, the remaining neck pillow core is placed on the other side of the head pillow core 4 and wrapped and shaped together with the combined head pillow core 4 and neck pillow core by the pillowcase 1.

[0022] Furthermore, the head pillow core 4 has a recessed mounting platform 41 on one side along its long side for placing the neck pillow core. The mounting platform 41 has two connected mounting surfaces. In this embodiment, the two mounting surfaces of the mounting platform 41 are a horizontal surface 43 and a vertical surface 42 that intersect perpendicularly. The neck pillow core has two mating surfaces that match the two mounting surfaces respectively. When the neck pillow core is placed on the mounting platform 41, the two mating surfaces are in close contact with the two mounting surfaces respectively. The arc-shaped surface 5 of the neck pillow core faces upward, and the neck pillow core and the head pillow core 4 are flush at their adjacent edges.

[0023] In this embodiment, there are three neck pillow cores with different firmness, namely the first neck pillow core 6, the second neck pillow core 7, and the third neck pillow core 8 shown in the figure. The three pillow cores have the same shape but different firmness. The mounting platform 41 and the neck pillow cores placed on it are symmetrical in the cross section along the vertical length direction of the pillow. The head pillow core 4 has a vertical wall on the side away from the mounting platform 41. The two neck pillow cores are stacked symmetrically on top of each other and attached to the vertical wall.

[0024] Pillowcase 1 has an opening structure formed by zippers. In this embodiment, for convenient and quick access to spare neck pillow cores and adjustment / replacement, pillowcase 1 has two opening structures formed by zippers. Both zippers extend along the long side of the pillow and respectively form an adjustment area zipper 2 on one side of the mounting platform 41 and a replacement area zipper 3 on the side where the folded neck pillow cores are placed. The adjustment area zipper 2 is located at the outer edge of the horizontal plane 43 on one side of the pillowcase 1, and the replacement area zipper 3 is located at the same height as the adjustment area zipper 2 on the other side of the pillowcase 1. By opening the zippers of both areas, three neck pillow cores can be taken out for replacement and adjustment. After adjustment, the two neck pillow cores are put back into the storage position inside the replacement area zipper for later use. The selected neck pillow cores and head pillow cores are combined to provide neck and head support.

[0025] Furthermore, the head pillow core 4 and the three neck pillow cores are each encased in an inner sleeve. The inner sleeve effectively prevents the two pillow cores from sticking together and reduces friction during disassembly and replacement, facilitating operation. In this embodiment, the head pillow core and each neck pillow core are made of sponge material. Sponge allows for the production of pillow cores with varying firmness to meet practical needs, and the cost is controllable.

[0026] This embodiment features two sections on the pillow core, providing different support for the head and neck. The firmness of the neck section can be adjusted by replacing the neck pillow core, offering users varying degrees of neck support. Users can choose and assemble a pillow that suits their individual needs, protecting the normal physiological curvature of the cervical spine and preventing the risk of cervical spine diseases caused or aggravated by sleeping on an uncomfortable pillow for a long time. The pillow core has been changed from a single-piece structure to a combination of a head pillow core and multiple neck pillow cores. Each neck pillow core can be combined with the head pillow core as an independent module, and then wrapped in a pillowcase to form a pillow. Changing different neck pillow cores allows adjustment of the firmness of the neck section on the pillow.

[0027] Furthermore, in this embodiment, when one of the three neck pillow cores is used in combination with the head pillow core 4, the remaining two neck pillow cores can also be placed outside the pillowcase 1, becoming as follows: Figure 4 In Embodiment 2, the pillowcase 1 only covers the combined head pillow core 4 and the selected neck pillow core. The figure uses the first neck pillow core 6 as an example. The pillowcase 1 has only one adjustment zipper 2. In Embodiment 2, the adjustment zipper 2 also needs to be unzipped to replace the neck pillow core and adjust the neck support.
