Description

Pillow with a cell structure

[0001] The present invention relates to a pillow having a cell structure, and more specifically, to a pillow having a cell structure composed of a plurality of through holes through which air can pass and vertical side walls formed between said through holes, which provides a cushioning effect while allowing for smooth ventilation.

[0002] Generally, pillows are used to comfortably support the head while sleeping, and most people use cotton pillows with cotton filling.

[0003] Cotton pillows provide a soft cushioning feel and support the head to prevent it from moving easily, offering a sense of stability during sleep. This cushioning is due to the fibers of the cotton filling forming a net-like structure, which provides resilience as air is continuously supplied into it.

[0004] However, a correspondingly large amount of cotton is required to provide good cushioning. Furthermore, as a cotton pillow is used continuously, its thickness thins due to the weight of the head, causing the cushioning to deteriorate easily and breathability to decrease.

[0005] In order to compensate for the problems of such cotton pillows, cushioned pillows are being developed recently using elastic materials such as latex rubber and polyethylene.

[0006] However, in the case of conventional pillows made of latex rubber, the breathability is poor, and as a result, heat is not dispersed, causing discomfort due to the hot and sweaty conditions.

[0033] The following detailed description of the present invention refers to the accompanying drawings, which illustrate specific embodiments in which the present invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present invention. It should be understood that various embodiments of the present invention are different but need not be mutually exclusive. For example, specific shapes, structures, and characteristics described herein in relation to one embodiment may be implemented in other embodiments without departing from the spirit and scope of the present invention. Furthermore, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the present invention. Accordingly, the following detailed description is not intended to be limiting, and the scope of the present invention is limited only by the appended claims, including all equivalents to those claimed therein, provided appropriately described. Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0034] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0035] As illustrated in FIGS. 1 to 6, a pillow having a cell structure according to an embodiment of the present invention is composed of a first cushion part (100), a band part (200), and a second cushion part (300).

[0036] The first cushion part (100) is placed on the bottom part of the pillow to support the second cushion part (300) and is made of a TPE material having elasticity.

[0037] TPE (Thermoplastic Elastomer) is a thermoplastic elastomer that possesses more flexible elasticity than rubber, enabling it to provide a rich cushioning feel, and its low price allows for reduced production costs.

[0038]

[0039] In addition, the first cushion portion (100) is composed of a plurality of first through holes (110) and a first side wall (120) formed between the first through holes (110).

[0040] The first through hole (110) is formed with a cross-section in the shape of a regular rhombus, and the first side wall (120) is formed in a shape in which a rhombus profile that surrounds the edge of the first through hole (110) is continuously arranged.

[0041] That is, the first side wall (120) is formed in a rhombus-shaped honeycomb structure.

[0042] In addition, the lower part of the first cushion part (100) is formed flat so as to provide fixing power so as not to easily slip when in contact with the floor surface.

[0043] The upper part of the first cushion part (100) is formed in a curved shape to correspond to the second cushion part (300) to be described later.

[0044] That is, on the upper part of the first cushion part (100), a first protrusion (150) protruding upwardly in a convex manner to support the head support part (350) to be described later, and a second protrusion (160) protruding upwardly in a convex manner to support the guide part (370) to be described later are formed.

[0045]

[0046] Meanwhile, the band portion (200) wraps around the edge of the first cushion portion (100) and functions to gather the first cushion portion (100).

[0047] The band portion (200) is made of TPE material, just like the first cushion portion (100), and is formed in a strip shape to wrap around the edge of the first cushion portion (100).

[0048] Additionally, it is preferable that the band portion (200) be spaced apart from the lower part of the first cushion portion (100) at a certain distance. For example, the distance from the lowest end of the first cushion portion (100) to the lowest end of the band portion (200) may be spaced 5 to 10 mm apart.

[0049] In this way, by positioning the lower end of the band portion (200) so as to be spaced apart from the lower end of the first cushion portion (100), air can be allowed to pass through the lower part of the first cushion portion (100), thereby facilitating air circulation.

[0050] In addition, the band portion (200) is integrally formed with the same material as the first cushion portion (100).

[0051] Of course, depending on the case, the band portion (200) may be made of a material different from the first cushion portion (100), for example, an elastic rubber band, or may be made of non-elastic leather or synthetic resin cord.

[0052] If made of non-elastic leather or string, the first cushion part (100) is prevented from spreading outward, thereby enabling a firmer cushioning sensation.

[0053] Thus, by providing the band portion (200) that wraps around the edge of the first cushion portion (100), the first cushion portion (100) is guided to gather towards the center, thereby preventing the first cushion portion (100) from spreading outward due to load, and thereby providing the effect of improving the elasticity of the first cushion portion (100).

[0054]

[0055] Meanwhile, the second cushion part (300) is positioned on the upper part of the first cushion part (100) and functions to support the user's head and neck, and has a firmer cushioning feel than the first cushion part (100).

[0056] Specifically, the second cushion portion (300) is composed of a plurality of second through holes (310) and a second side wall (320) formed between the second through holes (310).

[0057] The second through hole (310) is formed in a rhombus shape, excluding the head support part (350) to be described later, and is formed to be smaller, with a size that is 1 / 4 the size of the first through hole (110).

[0058] That is, since the second cushion part (300) has the second through holes (310) formed more densely than the first cushion part (100), the cross-sectional area of ​​the second side wall (320) is widened, and as a result, it has a firmer cushioning feel than the first cushion part (100).

[0059]

[0060] Additionally, the second cushion part (300) includes the headrest part (350), neckrest part (360), guide part (370), and earrest part (380).

[0061] The head support portion (350) is formed in the center of one end of the second cushion portion (300) and is formed in a downwardly concave curved shape to support the back of the head.

[0062] Additionally, the second through hole (310) of the head support portion (350) is formed with a hexagonal cross-section, and the second side wall (320) is also formed with hexagonal profiles arranged in succession, similar to a honeycomb structure.

[0063] The above head support portion (350) provides the effect of supporting the head more softly and stably by widening the cross-sectional area of ​​the second side wall (320).

[0064] The neck support portion (360) is connected to the head support portion (350) and is formed at the other end of the second cushion portion (300), and is formed to extend long to the left and right in an upwardly convex curved shape to support the neck.

[0065] In addition, the neck support (360) is formed in a concave, curved shape with the middle part being slightly lower than the left and right ends.

[0066] Here, as shown in FIG. 3, it is preferable that the lowest height (H1) of the neck support (360) be formed at 50-60% of the lowest height (H2) of the head support (350).

[0067] If the height of the neck support (360) is too high, the neck will be bent excessively, causing muscle fatigue to accumulate, and if the height of the neck support (360) is too low, the head will be bent forward, making breathing uncomfortable and disrupting deep sleep.

[0068] Therefore, it is preferable that the lowest height (H1) of the neck support part (360) be formed to be 55~65%, for example 60%, of the lowest height (H2) of the head support part (350).

[0069] The above-mentioned neck support (360) can help correct forward head posture by filling the empty space at the back of the neck to create a natural C-cover on the neck.

[0070] In addition, the neck support part (360) is formed such that the cross-sectional shape of the second through hole (310) is shaped like a rhombus, and its size is formed to be 1 / 4 the size of the first through hole (110).

[0071] Here, it is preferable that the maximum inner diameter of the second through hole (310) of the head support part (350) and the maximum inner diameter of the second through hole (310) of the neck support part (360) be formed to be the same.

[0072] The above-mentioned guide member (370) is positioned on both sides of the head support member (350) to prevent the head from moving left and right, and is formed in the shape of an upwardly convex curved surface.

[0073] Here, the maximum height of the induction part (370) is formed to be lower than the height of the neck support part (360).

[0074] The ear support portion (380) is formed between the neck support portion (360) and the guide portion (370) and is formed as a downwardly concave curved surface.

[0075] The above ear support (380) allows the user to sleep comfortably without discomfort by inserting and positioning the ear when lying on their side.

[0076]

[0077] Meanwhile, depending on the case, an air filter (400) may be further provided between the first cushion part (100) and the second cushion part (300).

[0078] As shown in FIGS. 5 and 6, a ventilation passage (390) is formed in the lower part of the second cushion part (300) to insert and place the air filter (400) into the second cushion part (300).

[0079] The above ventilation passage (390) is formed open at the lower part of the second cushion part (300) and is connected to a plurality of the second through holes (320).

[0080] Additionally, the above-mentioned ventilation passage (390) is positioned at the lower part of the headrest (350) and is formed to be long and open on both the left and right sides.

[0081] When the head is placed on the head support (350), an upward airflow is formed from the ventilation passage (390) to the second through hole (320) of the head support (350) due to the heat of the head.

[0082] The above air filter (400) is formed as a mesh-shaped cartridge filled with cypress wood chips.

[0083] The above air filter (400) is inserted into the air passage (390) and functions to absorb harmful substances in the air passing through the air passage (390).

[0084] That is, when air is introduced into the ventilation passage (390) from both sides of the second cushion part (300), it has a circulation structure in which air is discharged to the upper part of the headrest part (350) through the air filter (400), and at this time, harmful substances are absorbed as the air passes through the air filter (400).

[0085] In this way, the air passage (390) is formed in the lower part of the second cushion part (300), and the air filter (400) is provided in the air passage (390), thereby promoting air circulation so that heat is easily dispersed and absorbing harmful substances in the air to make the sleeping environment comfortable and provide the effect of improving the quality of sleep.

[0086]

[0087] Meanwhile, as shown in FIG. 7, an acupressure ball (500) may be provided on the upper part of the second cushion part (300).

[0088] The above acupressure ball (500) is formed in a hemispherical shape, and a connecting part (510) is provided at the bottom to be coupled to the second side wall (320).

[0089] Here, the above-mentioned acupressure ball (500) is made of an eco-friendly ceramic material, and the above-mentioned connecting part (510) is made of a plastic material having some elasticity.

[0090] In some cases, the above acupressure ball (500) may be made of silicone or wood.

[0091] The above coupling part (510) is for fixing the pressure ball (500) to the second side wall (320), and a fixing projection (511) is formed at the top of the coupling part (510) to fix the pressure ball (500), and a coupling groove (512) is formed at the bottom to insert and connect the top of the second side wall (320).

[0092] The above coupling groove (512) is formed such that its bottom width is narrower than the thickness of the second side wall (320).

[0093] Accordingly, when the above-mentioned coupling part (510) is coupled to the second side wall (320), force is applied to the coupling groove (51) to cause the coupling groove (512) to open due to elasticity, and after the second side wall (320) is inserted, the bottom of the coupling groove (512) narrows again due to elastic restoring force, and the second side wall (320) is pressurized and coupled to the coupling groove (512) so as not to easily come out again.

[0094] The above-mentioned acupressure ball (500) is provided on the upper part of the second cushion part (300) and can help with fatigue recovery and deep sleep by applying pressure to the head or neck to promote blood circulation.

[0095]

[0096] Additionally, depending on the case, as shown in FIGS. 5 and 6, a reinforcing member (600) may be further provided at the lower part of the first cushion portion (100).

[0097] The reinforcing member (600) is formed in the form of a thin sheet and may be made of polyester material.

[0098] The reinforcing member (600) is combined with the lower surface of the first cushion part (100) to support the edge of the first cushion part (100) so that it does not curl.

[0099] That is, when using the pillow, the load is concentrated around the headrest (350), and the edge portion bends in the direction of the headrest (350) due to the reaction. The reinforcing member (600) supports the lower surface of the first cushion (100) so that it does not curl up, thereby preventing the shape of the first cushion (100) from being deformed.

[0100]

[0101] The present invention is not limited thereto and may be modified in various forms by those skilled in the art without departing from the spirit and scope of the following appended claims; therefore, such modifications should be interpreted as being within the scope of the present invention.
