DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] With reference to FIGS. 1 to 8 for an ergonomic dual-purpose pillow for back sleeping and side sleeping in accordance with the present invention, the pillow 100 comprises a plurality of breathable pores 10 spaced from one another and disposed at the middle of the thickness of the pillow 100, and an elastic support column 20 formed between every two adjacent breathable pores 10; the plurality of elastic support columns 20 are disposed at the middle of the pillow 100 to constitute a central support section 101 capable of supporting the back of the neck and the back of the head of a user, so that both sides of the pillow 100 separately constitute a side support section 102 capable of stably supporting both sides of the head of the user.

[0030] In an embodiment disclosed in the figure, the plurality of breathable pores 10 and elastic support columns 20 spaced from one another and disposed in positions of the thickness of the pillow 100 are configured to be relative to the two side support sections 102, and the supporting forces of the breathable pores 10 and the elastic support columns 20 are assigned after a weight calculation. For example, the quantity, the width, the installation density, the depth of the pore or and the height of the support column of the breathable pores 10 and/or the elastic support column 20 can be fine-tuned by the weight calculation, so as to provide the supporting force for a corresponding head curvature profile and set the supporting force fed back by the central support section 101 to be smaller than that of the side support section 102. Regardless of back sleeping, side sleeping, or stomach sleeping, when a user changes the sleeping position, the user's cervical spine can substantially conform to a natural curve when no force is exerted and also can conform to ergonomics and naturally relax relevant parts of the muscle.

[0031] With reference to FIGS. 1 to 4 for the implementation of the breathable pores 10 and the elastic support columns 20, the pillow 100 can be integrally formed or comprised of a lower pad 30, and an upper pad 40 stacked on a top surface of the lower pad 30, and the of the upper pad 40 is an outer layer 50 provided for lying the user's head on the pillow 100.

[0032] The plurality of breathable pores 10 are formed by a plurality of parallel cut grooves 11 as shown in FIG. 1. When the pillow 100 is integrally formed, a slider (not shown) can be installed in a mold and used for mold opening after the cut grooves are formed and the slider is moved, so as to form the breathable pore 10 and the elastic support columns 20 in the thickness of the integrally formed pillow 100. In FIG. 2, the parallel cut grooves 11 are disposed on the bottom surface or the top surface of the upper pad 40 and/or the lower pad 30 respectively. After the upper pad 40 is stacked on the lower pad 30, the central support section 101 and two side support sections 102 are formed.

[0033] The plurality of cut grooves 11 of the central support section 101 and the plurality of cut grooves 11 of the two side support sections 102 are disposed on the same pad as shown in FIG. 2, or formed separately on the upper pad 40 and the lower pad 30 as shown in FIG. 4. In other words, the plurality of cut grooves 11 corresponding to the central support section 101 of the pillow 100 are disposed on the top surface of the middle of the lower pad 30, and the plurality of cut grooves 11 corresponding to the side support section 102 of the pillow 100 are disposed on the bottom surface of both sides of the upper pad 40.

[0034] In an embodiment, the upper pad 40 and the lower pad 30 can be flat sheets with an appropriate thickness, or a lower protrusion 41 is formed on a bottom surface of the middle of the upper pad 40 and a lower recession 31 is formed on a top surface of the middle of the lower pad 30 and engaged with the lower protrusion 41 as shown in FIG. 2; or an upper recession 42 is formed on a bottom surface of the middle of the upper pad 40 and an upper protrusion 32 is formed on a top surface of the middle of the lower pad 30 and engaged with the upper recession 42 as shown in FIG. 4, wherein the plurality of cut grooves 11 corresponding to the central support section 101 of the pillow 100 are disposed on the bottom surface of the upper recession 42 of the upper pad 40 or the top surface of the upper protrusion 32 of the lower pad 30.

[0035] Regardless of the plurality of cut grooves 11 disposed on the bottom surface or the top surface of the upper pad 40 and/or the lower pad 30, after the upper pad 40 is stacked on the lower pad 30, an elastic support column 20 is formed between the two adjacent cut grooves 11, so as to form the central support section 101 and two side support sections 102

[0036] Each support section can provide a different supporting force by changing the quantity, width, density, and height of the plurality of cut grooves 11 and elastic support columns 20. For example, the distance between two adjacent cut grooves 11 defines the thickness of the elastic support column 20, and if the widths of all cut grooves 11 are the same and the distance between two cut grooves 11 is reduced, then the thickness of the elastic support column 20 will be decreased, and the supporting force will be weaker.

[0037] On the other hand, if the distance between two adjacent cut grooves 11 in each support section is increased, then the arranged density will be less, the thickness of each elastic support column 20 in each support section will be increased, the supporting force will be stronger, and the overall supporting force of each support section will be increased.

[0038] Further, if the pillow 100 has a width of 65 cm, and the central support section 101 has a width of 33 cm, the widths of all cut grooves 11 in the central support section 101 are fixed, and the distance between two cut grooves 11 is 1.5 cm which is equivalent to that the thickness of each elastic support column 20 is 1.5 cm, then two units of supporting force will be obtained.

[0039] If the distance between every two of all cut grooves 11 in the central support section 101 is 1 cm, the thickness of each elastic support column 20 is reduced to 1 cm, and the arranged density is greater to reduce the overall supporting force of the central support section 101, then one unit of supporting force will be obtained.

[0040] On the other hand, if the distance between every two of all cut grooves 11 in the central support section 101 is 2 cm, and the arranged density is less, then the thickness of each elastic support column 20 in the central support section 101 will be increased to 2 cm, and the supporting force will be increased, and three units of supporting force will be obtained.

[0041] In addition, different supporting force of each support section can be set by the depth of the cut groove 11 and the height of the elastic support column 20. If the widths of all cut grooves 11 are the same and the depth of two adjacent cut grooves 11 becomes greater, then the height of the elastic support column 20 between two cut grooves 11 will become greater. When a user sleeps on the pillow, the elastic support column 20 provides a weaker supporting force, so that the support section will be sunken by weight. On the other hand, if the depth between two adjacent cut grooves 11 is smaller, then the height of the elastic support column 20 between two cut grooves 11 is smaller, and a stronger supporting force will be provided.

[0042] For example, if the widths of all cut grooves 11 in the central support section 101 are fixed, the distance between two cut grooves 11 is fixed, the depth of each cut groove 11 is 1.5 cm, which are equivalent to that each elastic support column 20 has a height of 1.5 cm, then two units of supporting force will be obtained.

[0043] If the depths of all cut grooves 11 in the central support section 101 are changed to 2 cm, then the height of each elastic support column 20 will be increased to 2 cm, and the supporting force of the central support section 101 will be weakened, and one unit of supporting force will be obtained.

[0044] On the other hand, if the depths of all cut grooves 11 in the central support section 101 are 1 cm, and the height of each elastic support column 20 is decreased to 1 cm, then the supporting force of the central support section 101 will be increased, and three units of supporting force will be obtained.

[0045] Similarly, the side support section 102 can have a supporting force different from that of the central support section 101 by fine-tuning the quantity, the width, and the density of the cut grooves 11 and the elastic support columns 20, the depth of the cut groove 11 or the height of the elastic support column 20 according to the aforementioned principle, and thus their description will not be repeated.

[0046] After the quantity, the width and the density of the cut grooves 11 and the elastic support columns 20, the depth of the pores or the height of the support column heights in each support section are configured according to a weight calculation, the supporting force fed back by the central support section 101 is set to be smaller than that of the side support section 102, and an appropriate supporting force can be fine-tuned to fit different users, so that when the users sleep on the pillow 100, the pillow 100 can produce recessions of different levels by different supporting forces to achieve the effects of covering the user's head and providing stable support to the head.

[0047] For example, when the user's sleeping position is a side sleeping position, and the user's head is situated at the top of the side support section 102, the side support section 102 will provide a larger supporting force and a smaller recession of the pillow 100, and the user's arm will not be pressed, since the side support section 102 and the central support section 101 will not have the large slope of the general side sleeping pillow, and the back of the head will not slip to the central support section 101 and will not let the user's neck to be unconsciously pushed back by force.

[0048] In addition, when the user switches from side sleeping or stomach sleeping to back sleeping, the natural deflection of the user's head lets the neck and the back of the head naturally roll to the top of the central support section 101 to obtain a moderate support from the central support section 101 without requiring to lift and move the head to another position, and it will not cause the formation of recessions by the slipping of the head.

[0049] When the user sleeps on the side as shown in the figure, the supporting force of the central support section 101 required for heightening the cervical spine by the shoulder is smaller, so that the central support section 101 still can appropriately support the cervical spine overcome the central recession of the conventional side sleeping pillow that is likely to cause the head to slip off and the neck to be pulled back by force, resulting in that the user cannot really relax.

[0050] Since the central support section 101 and the side support section 102 are not like the traditional pillow that uses the height difference to provide different supporting forces, therefore a greater slope will not be produced between the central support section 101 and the side support section 102. When a user lies the head on the central support section 101 switches the back sleeping or stomach sleeping to the side sleeping, the user's head can be deflected naturally and laid on the top of the side support section 102 without applying a force to lift and move the head to the side support section 102. In this way, it will not cause sleep interference or interruption.

[0051] In an embodiment, the outer layer 50 disposed at the top of the upper pad 40 can be integrally formed with the surface of the upper pad 40, or separately manufactured and then stacked onto the upper pad 40. In addition, the outer layer 50 can be designed with a curvature, so that from the perspective view of both sides of the pillow 100, the front section is relatively convex and attached to the back of the neck, and the middle section is relatively concave and attached to the back of the head, and such design is suitable for users using a soft mattress and/or having narrow shoulders.

[0052] In FIGS. 5 and 6, the pillow 100 further comprises an auxiliary pad 60 stacked onto the front of the upper pad 40, and the top surface or the bottom surface of both sides of the auxiliary pad 60 has a plurality of parallel cut grooves 11, so that the auxiliary pad 60 has a shoulder support section 61 formed relative to both sides of the pillow 100, and the plurality of cut grooves 11 of the auxiliary pad 60 and the plurality of cut grooves 11 on both sides of the upper pad 40 are aligned with one another respectively to allow the shoulder support section 61 of the auxiliary pad 60 to provide the same supporting force to both sides of the upper pad 40, and a neck support section 62 corresponding to a human cervical spine is formed at the middle of the auxiliary pad 60 to allow the user to have an appropriate support to the back of the neck when the user is lying on the pillow.

[0053] To improve the covering and supporting effects of the head by the pillow 100, the outer layer 50 of the pillow 100 is designed with the top surfaces of the two side support sections 102 facing the central support section 101 and tilting downwardly to form a structure with a greater thickness on both sides and a smaller thickness at the middle as shown in FIGS. 6 to 8, so that the user's is wrapped and supported when the user lies the head on the pillow, and such design is suitable for users using a hard mattress and/or having broad shoulders.

[0054] In FIGS. 7 and 8, the lower pad 30 and/or the outer layer 50 can be designed with a greater thickness on both sides and a smaller thickness in the middle, so that the upper pad 40 is in form of a flat sheet. After the outer layer 50 or lower pad 30 is stacked, the structure having the side support section 102 with a thickness greater than that of the central support section 101 still can be formed.

[0055] The central support section 101 and the plurality of breathable pores 10 of the side support section 102 can be configured to be parallel longitudinally or transversally or arranged in dot matrix on the pillow 100. In the figure, the longitudinal configuration is used for the illustration, and the front side and/or rear side of the longitudinal breathable pore 10 are penetrated through the thickness of the pillow 100, so that when a user lies on the pillow 100, each support section provides a supporting force, while compressing a plurality of breathable pores 10, and the air in each breathable pore 10 is compressed to produce a wind tunnel effect and discharged from the front side and/or the rear side of the pillow 100 to achieve breathable ventilation, and reduced sultry, and the pad and the outer layer can be a memory foam, a latex, a sponge, or a material with binchotan.

[0056] While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention as set forth in the claims.
