Description

TECHNICAL FIELD

[0001] The present disclosure relates to a mattress assembly.BACKGROUND ART

[0002] A mattress assembly can support a user who is lying down or sitting thereon. The mattress assembly may include a mattress for supporting a user and a main body for supporting the mattress. In addition, the mattress can be formed with varying levels of firmness to provide comfort to the user. However, conventional mattresses have a drawback in that their firmness cannot be adjusted to suit the body shape of every user supported by the mattress.

[0003] As a technique for controlling the firmness of a mattress, Korean Patent Application Publication No. 10-2018-0079957 entitled “Sleep care mattress” (Patent Document 1) of the present applicant discloses a mattress including a foam mattress for supporting a user, an air cell body part disposed below the foam mattress and provided with a plurality of air cells, and a control unit that supplies air to the plurality of air cells to control the firmness of the plurality of air cells.

[0004] However, although the sleep care mattress disclosed in Patent Document 1 can change the firmness of the plurality of air cells by inflating or deflating the plurality of air cells in order to provide firmness suitable for a user's body shape, Patent Document 1 as a whole does not present any awareness, implication, or motivation for the upward movement of the user's body. In other words, when air is injected into the plurality of air cells of the sleep care mattress in Patent Document 1, certain areas of the foam mattress cannot move upward to stretch the user's body.

[0005] As a technique for providing mattress firmness suitable for a user's body shape, Korean Patent Application Publication No. 10-2016-0002484 entitled “Mattress with adjustable firmness” (Patent Document 2) of the present applicant discloses a mattress including a firmness adjustment unit including an elastic body and an airbag, a mesh-type support positioned on the firmness adjustment unit, and an air injector for injecting air into the airbag.

[0006] However, in the mattress of Patent Document 2, the airbag can adjust the firmness of the mattress by increasing its volume depending on the amount of air injected into it and decreasing its volume depending on the amount of air discharged, but the increase or decrease in volume does not affect the upper portion of the mattress. In other words, Patent Document 2 does not disclose or suggest that a specific area of the support moves upward to stretch the user's body when air is injected into the airbag.DETAILED DESCRIPTION OF INVENTIONTechnical Problems

[0044] Hereinafter, a mattress assembly 1 according to one embodiment of the present disclosure will be described.

[0045] Referring to FIGS. 1 to 4, the mattress assembly 1 according to one embodiment of the present disclosure can support a user who is lying down or sitting thereon. The mattress assembly 1 may have a shape in which its length in a front-rear direction is longer than its length in a left-right direction. The mattress assembly 1 may include a main body unit 100, an air pocket unit 200, a topper 300, a cell unit 400, a pump 500, a controller 600, and a tube 700.

[0046] The main body unit 100 may be disposed below the cell unit 400 and accommodate the air pocket unit 200, the pump 500, and the controller 600. The main body unit 100 may be a housing that forms the outer appearance of the mattress assembly 1. In addition, a main body groove 110 may be formed in the main body unit 100.

[0047] The main body groove 110 may be a groove formed in the main body unit 100 to allow insertion of the tube 700 that provides a passage through which air flows to at least one of the air pocket unit 200 and the cell unit 400. The tube 700 may be placed inside the main body unit 100 by inserting the tube 700 into the main body groove 110, so that the tube 700 can be prevented from being damaged due to excessive expansion or pressurization even when air flows inside the tube 700.

[0048] For example, at least a portion of the main body groove 110 may be recessed downward from the bottom surface of the main body unit 100 and may extend in a direction inclined with respect to the front-rear direction. In addition, the main body groove 110 may be provided as a plurality of main body grooves. For example, one of the plurality of main body grooves 110 may be a groove into which at least a portion of a tube 700 providing a passage for air supplied to the air pocket unit 200 is inserted, and another one may be a groove into which at least a portion of a tube 700 providing a passage for air discharged from the air pocket unit 200 is inserted. As another example, one of the plurality of main body grooves 110 may be a groove into which at least a part of a tube 700 providing a passage for air to flow into one of a plurality of air receiving parts 411 of the cell unit 400, which will be described later, is inserted, and another one may be a groove into which at least a portion of a tube 700 providing a passage for air to flow into another one of the plurality of air receiving parts 411 is inserted.

[0049] The air pocket unit 200 is accommodated in the main body unit 100 and may be configured to change its firmness as air is introduced or discharged. The firmness of the air pocket unit 200 may be adjusted to suit a user's body supported by the mattress assembly 1 or may be changed to massage the user. The air pocket unit 200 may be formed to have an area larger than that of a plurality of cell members 410, which will be described later. The air pocket unit 200 may include a plurality of air pockets 210 and an air pocket support member 220.

[0050] The plurality of air pockets 210 may be configured to receive air pressurized by the pump 500. In addition, the plurality of air pockets 210 may be arranged horizontally. At least some of the plurality of air pockets 210 may be configured to independently receive and discharge air, allowing them to have different levels of firmness. In other words, the plurality of air pockets 210 may provide different cushioning sensations for different parts of the user's body. For example, the cushioning sensation provided by some of the plurality of air pockets 210 to the user's head and back, the cushioning sensation provided by others of the plurality of air pockets 210 to the user's waist and hips, and the cushioning sensation provided by still others of the plurality of air pockets 210 to the user's legs and feet may be different from each other. In addition, each of the plurality of air pockets 210 may be formed smaller than the left-right length and the front-back length of the air receiving part 411 to be described later.

[0051] The air pocket support member 220 may be disposed below the plurality of air pockets 210 to support the plurality of air pockets 210. In other words, the air pocket support member 220 may be extended horizontally and formed to have the same size as that of the plurality of air pockets 210. With the air pocket support member 220, the plurality of air pockets 210 can expand upward from the air pocket support member 220 as air is introduced therein, or contract toward the air pocket support member 220 as air is discharged therefrom. In addition, the air pocket support member 220 may be formed with a pocket groove 221 in which at least a portion of a tube 700 providing a passage through which air flows to the plurality of air pockets 210 or through which air discharged from the plurality of air pockets 210 flows. The pocket groove 221 may be recessed downward from an upper surface of the air pocket support member 220 and extend in the front-rear direction.

[0052] The topper 300 can support the user's body. In other words, the user can lie down or sit on the topper 300. The topper 300 may be disposed on top of the cell unit 400. The length of the topper 300 in the front-rear direction may be greater than the length in the left-right direction.

[0053] Referring further to FIGS. 5 and 6, the cell unit 400 can move a portion of the topper 300 in the up-down direction to stretch the user's body supported on the topper 300. For example, the cell unit 400 can move a region of the topper 300 where the user's waist is located upward and then downward to stretch the user's waist. When a portion of the topper 300 is moved upward by the cell unit 400, the portion of the topper 300 can be positioned higher than other portions of the topper 300. In addition, the cell unit 400 can move a portion of the topper 300 upward and downward multiple times. The cell unit 400 may include a cell member 410, a cell support part 420, a fixing part 430, and a Velcro 440.

[0054] The cell member 410 can receive or discharge air to move a portion of the topper 300 in the up-down direction. The cell member 410 may be provided as a plurality of cell members. The plurality of cell members 410 may be arranged to be spaced apart from each other in the front-rear direction. Further, at least some of the plurality of cell members 410 may expand to different heights when inflated by air introduced therein. In addition, the height of the expanded cell members 410 may be greater than the thickness of the topper 300 in the up-down direction. The plurality of cell members 410 may include a first cell member, a second cell member, and a third cell member.

[0055] The first cell member may be positioned forward of the second cell member and the third cell member. Here, the forward may refer to the direction in which the user's head is located when the user lies down on the mattress assembly. For example, when viewed from above, the first cell member may be arranged to correspond to a region of the topper 300 where the user's cervical spine and head are supported so that the user's cervical spine and head are stretched. Further, the height of the first cell member when expanded may be lower than the heights of the second cell member and the third cell member when they are expanded. For example, the height of the first cell member when expanded may be between 90 mm and 100 mm. In addition, the height of the first cell member when expanded may be greater than the thickness of the topper 300.

[0056] The second cell member may be positioned between the first cell member and the third cell member. For example, when viewed from above, the second cell member may be arranged to correspond to a region of the topper 300 where the user's back and waist are supported so that the user's back and waist are stretched. The height of the second cell member when expanded may be greater than the height of the first cell member when expanded and less than the height of the third cell member when expanded. For example, the height of the second cell member when expanded may be between 150 mm and 170 mm.

[0057] The third cell member may be positioned rearward of the first cell member and the second cell member. Here, the rearward may refer to the direction in which the user's feet are located when the user lies down on the mattress assembly. For example, when viewed from above, the third cell member may be arranged to correspond to a region of the topper 300 where the user's legs and feet are supported so that the user's legs and feet are stretched. In addition, the height of the third cell member when expanded may be greater than the heights of the first cell member and the second cell member when they are expanded. For example, the height of the third cell member when expanded may be between 180 mm and 200 mm.

[0058] Referring further to FIGS. 7 and 8, the cell member 410 may include an air receiving part 411, an air flow channel 412, and a nipple 413.

[0059] The air receiving part 411 may provide a receiving space for air that is introduced therein. The air receiving part 411 can be expanded upward by the air introduced therein or contracted by discharging the air to move a portion of the topper 300 up and down. The air receiving part 411 may be disposed between the topper 300 and the cell support part 420. The left-right length and front-rear length of the air receiving part 411 may differ, with one being smaller than the other. In addition, the front-rear length of the air receiving part 411 may be smaller than the front-rear length of the air pocket unit 200. The air receiving part 411 may include an upper sheet 411a and a lower sheet 411b.

[0060] The upper sheet 411a may be connected to the lower sheet 411b to provide the receiving space together with the lower sheet 411b. Further, when the air receiving part 411 is expanded, the upper sheet 411a can contact a lower surface of the topper 300 to move the topper 300 upward. In addition, when the air receiving part 411 is contracted, the upper sheet 411a can be positioned below an upper surface of the cell support part 420 to move the topper 300 downward.

[0061] The lower sheet 411b may have edges connected to edges of the upper sheet 411a to provide the receiving space for air together with the upper sheet 411a. The lower sheet 411b may be supported by the cell support part 420. When the air receiving part 411 is expanded, the central portions of the lower sheet 411b and the upper sheet 411a may be spaced apart from each other. In addition, when the air receiving part 411 is contracted, the distance between the central portions of the lower sheet 411b and the upper sheet 411a may decrease, allowing them to come into close contact with each other.

[0062] Referring further to FIGS. 9 and 10, the air receiving part 411 may be provided as a plurality of air receiving parts, and one of the plurality of air receiving parts 411 may be disposed above another. For example, the third cell member may include a plurality of air receiving parts 411 arranged one above another. A communication hole 411c through which air flows may be formed between the plurality of air receiving parts 411. In other words, air may flow into the lower air receiving part 411 among the plurality of air receiving parts 411 and then flow to the upper air receiving part 411 through the communication hole 411c.

[0063] Further, the cell member 410 may include a plurality of air receiving parts 411 arranged in the left-right direction. The horizontal area of each of the plurality of air receiving parts 411 may be smaller than the horizontal area of the air pocket 210, but the idea of the present disclosure is not necessarily limited thereto. In addition, the plurality of air receiving parts 411 may be expanded simultaneously upon air inflow or contracted simultaneously to discharge air to move a portion of the topper 300 in the up-down direction.

[0064] Furthermore, when viewed from above, the cell member 410 may be positioned within the entire region of the cell support part 420. In other words, the cell member 410 may be formed to have a horizontal area smaller than that of the air pocket unit 200, and may be disposed within a cell-member arrangement region, which is a portion of the entire region of the cell support part 420, when viewed from above. The cell member 410 disposed within the cell-member arrangement region may include a plurality of air receiving parts 411 that are positioned in contact with each other.

[0065] In addition, the cell-member arrangement region may be provided as a plurality of cell-member arrangement regions, and the plurality of cell-member arrangement regions may be arranged to be spaced apart from each other in the front-rear direction within the entire region of the cell support part 420. In other words, when viewed from above, the plurality of cell members 410 may be arranged to be spaced apart from each other in the front-rear direction within the entire region of the cell support part 420. The spacing between the plurality of cell-member arrangement regions in the front-rear direction may be greater than the average length of the plurality of cell-member arrangement regions in the front-rear direction. Further, some of the plurality of cell-member arrangement regions may be arranged outside the area of the air pocket unit 200 when viewed from above.

[0066] The air flow channel 412 is disposed inside the air receiving part 411 and extends toward both sides of the air receiving part 411 to provide a passage through which air introduced into the air receiving part 411 flows toward both sides of the air receiving part 411. For example, the air receiving part 411 may extend in the left-right direction. Through the air flow channel 412, air introduced into the air receiving part 411 can flow smoothly in the left-right direction. In addition, the air flow channel 412 can guide air circulation in the left-right direction within the air receiving part 411 when the air receiving part 411 is in an expanded state. By means of the air flow channel 412, even when a portion of the air receiving part 411 is compressed by the user's body, air can be circulated inside the air receiving part 411, which prevents a localized increase in pressure compared to other areas within the air receiving part 411.

[0067] The nipple 413 may be connected to the air receiving part 411 and the tube 700 to provide a passage through which air flowing in the tube 700 flows into the air receiving part 411 or air discharged from the air receiving part 411 flows to the tube 700. The nipple 413 may be connected to a lower surface of the air receiving part 411. In other words, the nipple 413 may be fusion-bonded and fixed to the lower sheet 411b.

[0068] The cell support part 420 may be disposed between the topper 300 and the air pocket unit 200 to support the cell member 410. For example, the cell member 410 may be a mattress. A cell groove 421 may be formed in the cell support part 420, into which the cell member 410 can be inserted and seated. The cell groove 421 may be recessed downward from the upper surface of the cell support part 420 and may extend in the left-right direction. In addition, the cell groove 421 may form a gap with the cell member 410 when the cell support part 420 is viewed from above. In other words, the length of the cell groove 421 in the front-rear direction may be greater than the length of the cell member 410 in the front-rear direction. In addition, due to the cell groove 421, when air is discharged from the cell member 410 beyond a predetermined amount, the upper surface of the air receiving part 411 can be positioned below the upper surface of the cell support part 420.

[0069] In addition, a cell hole 422 through which the tube 700 passes may be formed in the cell support part 420. Through the cell hole 422, the tube 700 may be connected to the nipple 413 while passing through the cell support part 420. The cell hole 422 may be formed in the cell groove 421.

[0070] The fixing part 430 is disposed in the cell groove 421, has a sheet shape, and can fix the cell member 410 to the cell support part 420. For example, the fixing part 430 can be hot-melt bonded to the cell groove 421. With the fixing part 430, when air is introduced in the cell member 410, the cell member 410 can expand upward while being supported on the cell support part 420.

[0071] The Velcro 440 may be disposed on the lower surface of the air receiving part 411 and attached to the fixing part 430. In other words, the Velcro 440 may extend in the left-right direction and be attached to the lower surface of the lower sheet 411b. By means of the Velcro 440, the cell member 410 can be fixed to the fixing part 430.

[0072] The pump 500 may be operated to inject air into one or more of the air receiving part 411 and the air pocket unit 200, or to discharge air from the air receiving part 411. In other words, the pump 500 may inflate one or more of the plurality of air pockets 210 of the air pocket unit 200 to expand the plurality of air pockets. In addition, the pump may inflate one or more of the plurality of cell members 410 to expand one or more of the plurality of cell members 410, or deflate one or more of the plurality of cell members 410 to contract one or more of the plurality of cell members 410.

[0073] The controller 600 may control the pump 500 so that air is injected into one or more of the air receiving part 411 and the air pocket unit 200, or so that air is discharged from the air receiving part 411.

[0074] The aforementioned controller 600 may be implemented by a computing device including a microprocessor, a measuring device such as a sensor, and a memory, and since the implementation method thereof is obvious to those skilled in the art, a more detailed description thereof will be omitted.

[0075] The tube 700 can provide a passage for air to flow by connecting the pump 500, the air receiving part 411, and the air pocket unit 200. A portion of the tube 700 may be arranged in the pocket groove 221 to be connected to the air pocket unit 200. In addition, another portion of the tube 700 may be inserted into the main body groove 110 to be connected to the nipple 413, and may pass through the cell hole 422.

[0076] Hereinafter, the operation and effects of the mattress assembly 1 according to one embodiment of the present disclosure will be described.

[0077] The air receiving part 411 of the mattress assembly 1 according to one embodiment of the present disclosure can be expanded by air introduced therein or contracted by discharging the air to move a portion of the topper 300 in the vertical direction, so that a portion of the user's body supported by the topper 300 can be stretched while moving in the vertical direction. The vertical direction may refer to the up-down direction perpendicular to the ground or the upper surface of the topper 300.

[0078] Further, since the cell member 410 can be supported on the cell support part 420 by the fixing part 430 and the Velcro 440, the air receiving part 411 can be effectively expanded while maintaining its horizontal position.

[0079] Furthermore, when air is discharged from the air receiving part 411, the upper surface of the air receiving part 411 can be positioned below the upper surface of the cell support part 420 and spaced apart from the lower surface of the topper, so that the topper 300 can return to a state where it is not protruded upward.

[0080] In addition, since air can flow in the left-right direction inside the air receiving part 411 through the air flow channel 412, the center and the left and right sides of the air receiving part 411 can be expanded uniformly when the air receiving part 411 is inflated.

[0081] Further, when the plurality of cell members 410 are expanded, at least some of the plurality of cell members 410 can be expanded to different heights, so that the stretching intensity can be set differently for each part of the user's body.

[0082] Although the embodiments of the present disclosure have been described as specific embodiments, this is merely an example, and the present disclosure should be construed as having the broadest scope according to the technical idea disclosed herein without being limited thereto. Those skilled in the art may implement a pattern of a shape not indicated herein by combining / substituting the disclosed embodiments, but this also does not deviate from the scope of the present disclosure.

TECHNICAL FIELD

[0001] The present disclosure relates to a mattress assembly.BACKGROUND ART

[0002] A mattress assembly can support a user who is lying down or sitting thereon. The mattress assembly may include a mattress for supporting a user and a main body for supporting the mattress. In addition, the mattress can be formed with varying levels of firmness to provide comfort to the user. However, conventional mattresses have a drawback in that their firmness cannot be adjusted to suit the body shape of every user supported by the mattress.

[0003] As a technique for controlling the firmness of a mattress, Korean Patent Application Publication No. 10-2018-0079957 entitled “Sleep care mattress” (Patent Document 1) of the present applicant discloses a mattress including a foam mattress for supporting a user, an air cell body part disposed below the foam mattress and provided with a plurality of air cells, and a control unit that supplies air to the plurality of air cells to control the firmness of the plurality of air cells.

[0004] However, although the sleep care mattress disclosed in Patent Document 1 can change the firmness of the plurality of air cells by inflating or deflating the plurality of air cells in order to provide firmness suitable for a user's body shape, Patent Document 1 as a whole does not present any awareness, implication, or motivation for the upward movement of the user's body. In other words, when air is injected into the plurality of air cells of the sleep care mattress in Patent Document 1, certain areas of the foam mattress cannot move upward to stretch the user's body.

[0005] As a technique for providing mattress firmness suitable for a user's body shape, Korean Patent Application Publication No. 10-2016-0002484 entitled “Mattress with adjustable firmness” (Patent Document 2) of the present applicant discloses a mattress including a firmness adjustment unit including an elastic body and an airbag, a mesh-type support positioned on the firmness adjustment unit, and an air injector for injecting air into the airbag.

[0006] However, in the mattress of Patent Document 2, the airbag can adjust the firmness of the mattress by increasing its volume depending on the amount of air injected into it and decreasing its volume depending on the amount of air discharged, but the increase or decrease in volume does not affect the upper portion of the mattress. In other words, Patent Document 2 does not disclose or suggest that a specific area of the support moves upward to stretch the user's body when air is injected into the airbag.DETAILED DESCRIPTION OF INVENTIONTechnical Problems

[0037] Hereinafter, specific embodiments for implementing the technical idea of the present disclosure will be described in detail with reference to the drawings.

[0038] In addition, in describing the present disclosure, when it is determined that detailed descriptions of known configurations or functions may obscure the gist of the present disclosure, the detailed descriptions will be omitted.

[0039] Moreover, it should be understood that when a component is referred to as being ‘contacted with’, ‘supported by’, or ‘connected to’ another component, it may be directly contacted with, supported by, or connected to another component, but other components may exist between the components.

[0040] The terms used in the present specification are only used for describing the specific embodiments and are not intended to limit the present disclosure. Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0041] In addition, in the present specification, expressions such as upper, lower, side, etc. are described based on the drawings, and it is made clear in advance that they may be expressed differently if the direction of the object is changed. For the same reason, some components in the accompanying drawings are exaggerated, omitted, or schematically illustrated, and the size of each component does not entirely reflect the actual size.

[0042] Further, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but the components are not limited by these terms. These terms are only used to distinguish one component from another.

[0043] The meaning of “including” used in the present specification specifies specific features, regions, integers, steps, operations, elements and / or components, and does not exclude the presence or addition of other specific features, regions, integers, steps, operations, elements, components, and / or groups.

[0044] Hereinafter, a mattress assembly 1 according to one embodiment of the present disclosure will be described.

[0045] Referring to FIGS. 1 to 4, the mattress assembly 1 according to one embodiment of the present disclosure can support a user who is lying down or sitting thereon. The mattress assembly 1 may have a shape in which its length in a front-rear direction is longer than its length in a left-right direction. The mattress assembly 1 may include a main body unit 100, an air pocket unit 200, a topper 300, a cell unit 400, a pump 500, a controller 600, and a tube 700.

[0046] The main body unit 100 may be disposed below the cell unit 400 and accommodate the air pocket unit 200, the pump 500, and the controller 600. The main body unit 100 may be a housing that forms the outer appearance of the mattress assembly 1. In addition, a main body groove 110 may be formed in the main body unit 100.

[0047] The main body groove 110 may be a groove formed in the main body unit 100 to allow insertion of the tube 700 that provides a passage through which air flows to at least one of the air pocket unit 200 and the cell unit 400. The tube 700 may be placed inside the main body unit 100 by inserting the tube 700 into the main body groove 110, so that the tube 700 can be prevented from being damaged due to excessive expansion or pressurization even when air flows inside the tube 700.

[0048] For example, at least a portion of the main body groove 110 may be recessed downward from the bottom surface of the main body unit 100 and may extend in a direction inclined with respect to the front-rear direction. In addition, the main body groove 110 may be provided as a plurality of main body grooves. For example, one of the plurality of main body grooves 110 may be a groove into which at least a portion of a tube 700 providing a passage for air supplied to the air pocket unit 200 is inserted, and another one may be a groove into which at least a portion of a tube 700 providing a passage for air discharged from the air pocket unit 200 is inserted. As another example, one of the plurality of main body grooves 110 may be a groove into which at least a part of a tube 700 providing a passage for air to flow into one of a plurality of air receiving parts 411 of the cell unit 400, which will be described later, is inserted, and another one may be a groove into which at least a portion of a tube 700 providing a passage for air to flow into another one of the plurality of air receiving parts 411 is inserted.

[0049] The air pocket unit 200 is accommodated in the main body unit 100 and may be configured to change its firmness as air is introduced or discharged. The firmness of the air pocket unit 200 may be adjusted to suit a user's body supported by the mattress assembly 1 or may be changed to massage the user. The air pocket unit 200 may be formed to have an area larger than that of a plurality of cell members 410, which will be described later. The air pocket unit 200 may include a plurality of air pockets 210 and an air pocket support member 220.

[0050] The plurality of air pockets 210 may be configured to receive air pressurized by the pump 500. In addition, the plurality of air pockets 210 may be arranged horizontally. At least some of the plurality of air pockets 210 may be configured to independently receive and discharge air, allowing them to have different levels of firmness. In other words, the plurality of air pockets 210 may provide different cushioning sensations for different parts of the user's body. For example, the cushioning sensation provided by some of the plurality of air pockets 210 to the user's head and back, the cushioning sensation provided by others of the plurality of air pockets 210 to the user's waist and hips, and the cushioning sensation provided by still others of the plurality of air pockets 210 to the user's legs and feet may be different from each other. In addition, each of the plurality of air pockets 210 may be formed smaller than the left-right length and the front-back length of the air receiving part 411 to be described later.

[0051] The air pocket support member 220 may be disposed below the plurality of air pockets 210 to support the plurality of air pockets 210. In other words, the air pocket support member 220 may be extended horizontally and formed to have the same size as that of the plurality of air pockets 210. With the air pocket support member 220, the plurality of air pockets 210 can expand upward from the air pocket support member 220 as air is introduced therein, or contract toward the air pocket support member 220 as air is discharged therefrom. In addition, the air pocket support member 220 may be formed with a pocket groove 221 in which at least a portion of a tube 700 providing a passage through which air flows to the plurality of air pockets 210 or through which air discharged from the plurality of air pockets 210 flows. The pocket groove 221 may be recessed downward from an upper surface of the air pocket support member 220 and extend in the front-rear direction.

[0052] The topper 300 can support the user's body. In other words, the user can lie down or sit on the topper 300. The topper 300 may be disposed on top of the cell unit 400. The length of the topper 300 in the front-rear direction may be greater than the length in the left-right direction.

[0053] Referring further to FIGS. 5 and 6, the cell unit 400 can move a portion of the topper 300 in the up-down direction to stretch the user's body supported on the topper 300. For example, the cell unit 400 can move a region of the topper 300 where the user's waist is located upward and then downward to stretch the user's waist. When a portion of the topper 300 is moved upward by the cell unit 400, the portion of the topper 300 can be positioned higher than other portions of the topper 300. In addition, the cell unit 400 can move a portion of the topper 300 upward and downward multiple times. The cell unit 400 may include a cell member 410, a cell support part 420, a fixing part 430, and a Velcro 440.

[0054] The cell member 410 can receive or discharge air to move a portion of the topper 300 in the up-down direction. The cell member 410 may be provided as a plurality of cell members. The plurality of cell members 410 may be arranged to be spaced apart from each other in the front-rear direction. Further, at least some of the plurality of cell members 410 may expand to different heights when inflated by air introduced therein. In addition, the height of the expanded cell members 410 may be greater than the thickness of the topper 300 in the up-down direction. The plurality of cell members 410 may include a first cell member, a second cell member, and a third cell member.

[0055] The first cell member may be positioned forward of the second cell member and the third cell member. Here, the forward may refer to the direction in which the user's head is located when the user lies down on the mattress assembly. For example, when viewed from above, the first cell member may be arranged to correspond to a region of the topper 300 where the user's cervical spine and head are supported so that the user's cervical spine and head are stretched. Further, the height of the first cell member when expanded may be lower than the heights of the second cell member and the third cell member when they are expanded. For example, the height of the first cell member when expanded may be between 90 mm and 100 mm. In addition, the height of the first cell member when expanded may be greater than the thickness of the topper 300.

[0056] The second cell member may be positioned between the first cell member and the third cell member. For example, when viewed from above, the second cell member may be arranged to correspond to a region of the topper 300 where the user's back and waist are supported so that the user's back and waist are stretched. The height of the second cell member when expanded may be greater than the height of the first cell member when expanded and less than the height of the third cell member when expanded. For example, the height of the second cell member when expanded may be between 150 mm and 170 mm.

[0057] The third cell member may be positioned rearward of the first cell member and the second cell member. Here, the rearward may refer to the direction in which the user's feet are located when the user lies down on the mattress assembly. For example, when viewed from above, the third cell member may be arranged to correspond to a region of the topper 300 where the user's legs and feet are supported so that the user's legs and feet are stretched. In addition, the height of the third cell member when expanded may be greater than the heights of the first cell member and the second cell member when they are expanded. For example, the height of the third cell member when expanded may be between 180 mm and 200 mm.

[0058] Referring further to FIGS. 7 and 8, the cell member 410 may include an air receiving part 411, an air flow channel 412, and a nipple 413.

[0059] The air receiving part 411 may provide a receiving space for air that is introduced therein. The air receiving part 411 can be expanded upward by the air introduced therein or contracted by discharging the air to move a portion of the topper 300 up and down. The air receiving part 411 may be disposed between the topper 300 and the cell support part 420. The left-right length and front-rear length of the air receiving part 411 may differ, with one being smaller than the other. In addition, the front-rear length of the air receiving part 411 may be smaller than the front-rear length of the air pocket unit 200. The air receiving part 411 may include an upper sheet 411a and a lower sheet 411b.

[0060] The upper sheet 411a may be connected to the lower sheet 411b to provide the receiving space together with the lower sheet 411b. Further, when the air receiving part 411 is expanded, the upper sheet 411a can contact a lower surface of the topper 300 to move the topper 300 upward. In addition, when the air receiving part 411 is contracted, the upper sheet 411a can be positioned below an upper surface of the cell support part 420 to move the topper 300 downward.

[0061] The lower sheet 411b may have edges connected to edges of the upper sheet 411a to provide the receiving space for air together with the upper sheet 411a. The lower sheet 411b may be supported by the cell support part 420. When the air receiving part 411 is expanded, the central portions of the lower sheet 411b and the upper sheet 411a may be spaced apart from each other. In addition, when the air receiving part 411 is contracted, the distance between the central portions of the lower sheet 411b and the upper sheet 411a may decrease, allowing them to come into close contact with each other.

[0062] Referring further to FIGS. 9 and 10, the air receiving part 411 may be provided as a plurality of air receiving parts, and one of the plurality of air receiving parts 411 may be disposed above another. For example, the third cell member may include a plurality of air receiving parts 411 arranged one above another. A communication hole 411c through which air flows may be formed between the plurality of air receiving parts 411. In other words, air may flow into the lower air receiving part 411 among the plurality of air receiving parts 411 and then flow to the upper air receiving part 411 through the communication hole 411c.

[0063] Further, the cell member 410 may include a plurality of air receiving parts 411 arranged in the left-right direction. The horizontal area of each of the plurality of air receiving parts 411 may be smaller than the horizontal area of the air pocket 210, but the idea of the present disclosure is not necessarily limited thereto. In addition, the plurality of air receiving parts 411 may be expanded simultaneously upon air inflow or contracted simultaneously to discharge air to move a portion of the topper 300 in the up-down direction.

[0064] Furthermore, when viewed from above, the cell member 410 may be positioned within the entire region of the cell support part 420. In other words, the cell member 410 may be formed to have a horizontal area smaller than that of the air pocket unit 200, and may be disposed within a cell-member arrangement region, which is a portion of the entire region of the cell support part 420, when viewed from above. The cell member 410 disposed within the cell-member arrangement region may include a plurality of air receiving parts 411 that are positioned in contact with each other.

[0065] In addition, the cell-member arrangement region may be provided as a plurality of cell-member arrangement regions, and the plurality of cell-member arrangement regions may be arranged to be spaced apart from each other in the front-rear direction within the entire region of the cell support part 420. In other words, when viewed from above, the plurality of cell members 410 may be arranged to be spaced apart from each other in the front-rear direction within the entire region of the cell support part 420. The spacing between the plurality of cell-member arrangement regions in the front-rear direction may be greater than the average length of the plurality of cell-member arrangement regions in the front-rear direction. Further, some of the plurality of cell-member arrangement regions may be arranged outside the area of the air pocket unit 200 when viewed from above.

[0066] The air flow channel 412 is disposed inside the air receiving part 411 and extends toward both sides of the air receiving part 411 to provide a passage through which air introduced into the air receiving part 411 flows toward both sides of the air receiving part 411. For example, the air receiving part 411 may extend in the left-right direction. Through the air flow channel 412, air introduced into the air receiving part 411 can flow smoothly in the left-right direction. In addition, the air flow channel 412 can guide air circulation in the left-right direction within the air receiving part 411 when the air receiving part 411 is in an expanded state. By means of the air flow channel 412, even when a portion of the air receiving part 411 is compressed by the user's body, air can be circulated inside the air receiving part 411, which prevents a localized increase in pressure compared to other areas within the air receiving part 411.

[0067] The nipple 413 may be connected to the air receiving part 411 and the tube 700 to provide a passage through which air flowing in the tube 700 flows into the air receiving part 411 or air discharged from the air receiving part 411 flows to the tube 700. The nipple 413 may be connected to a lower surface of the air receiving part 411. In other words, the nipple 413 may be fusion-bonded and fixed to the lower sheet 411b.

[0068] The cell support part 420 may be disposed between the topper 300 and the air pocket unit 200 to support the cell member 410. For example, the cell member 410 may be a mattress. A cell groove 421 may be formed in the cell support part 420, into which the cell member 410 can be inserted and seated. The cell groove 421 may be recessed downward from the upper surface of the cell support part 420 and may extend in the left-right direction. In addition, the cell groove 421 may form a gap with the cell member 410 when the cell support part 420 is viewed from above. In other words, the length of the cell groove 421 in the front-rear direction may be greater than the length of the cell member 410 in the front-rear direction. In addition, due to the cell groove 421, when air is discharged from the cell member 410 beyond a predetermined amount, the upper surface of the air receiving part 411 can be positioned below the upper surface of the cell support part 420.

[0069] In addition, a cell hole 422 through which the tube 700 passes may be formed in the cell support part 420. Through the cell hole 422, the tube 700 may be connected to the nipple 413 while passing through the cell support part 420. The cell hole 422 may be formed in the cell groove 421.

[0070] The fixing part 430 is disposed in the cell groove 421, has a sheet shape, and can fix the cell member 410 to the cell support part 420. For example, the fixing part 430 can be hot-melt bonded to the cell groove 421. With the fixing part 430, when air is introduced in the cell member 410, the cell member 410 can expand upward while being supported on the cell support part 420.

[0071] The Velcro 440 may be disposed on the lower surface of the air receiving part 411 and attached to the fixing part 430. In other words, the Velcro 440 may extend in the left-right direction and be attached to the lower surface of the lower sheet 411b. By means of the Velcro 440, the cell member 410 can be fixed to the fixing part 430.

[0072] The pump 500 may be operated to inject air into one or more of the air receiving part 411 and the air pocket unit 200, or to discharge air from the air receiving part 411. In other words, the pump 500 may inflate one or more of the plurality of air pockets 210 of the air pocket unit 200 to expand the plurality of air pockets. In addition, the pump may inflate one or more of the plurality of cell members 410 to expand one or more of the plurality of cell members 410, or deflate one or more of the plurality of cell members 410 to contract one or more of the plurality of cell members 410.

[0073] The controller 600 may control the pump 500 so that air is injected into one or more of the air receiving part 411 and the air pocket unit 200, or so that air is discharged from the air receiving part 411.

[0074] The aforementioned controller 600 may be implemented by a computing device including a microprocessor, a measuring device such as a sensor, and a memory, and since the implementation method thereof is obvious to those skilled in the art, a more detailed description thereof will be omitted.

[0075] The tube 700 can provide a passage for air to flow by connecting the pump 500, the air receiving part 411, and the air pocket unit 200. A portion of the tube 700 may be arranged in the pocket groove 221 to be connected to the air pocket unit 200. In addition, another portion of the tube 700 may be inserted into the main body groove 110 to be connected to the nipple 413, and may pass through the cell hole 422.

[0076] Hereinafter, the operation and effects of the mattress assembly 1 according to one embodiment of the present disclosure will be described.

[0077] The air receiving part 411 of the mattress assembly 1 according to one embodiment of the present disclosure can be expanded by air introduced therein or contracted by discharging the air to move a portion of the topper 300 in the vertical direction, so that a portion of the user's body supported by the topper 300 can be stretched while moving in the vertical direction. The vertical direction may refer to the up-down direction perpendicular to the ground or the upper surface of the topper 300.

[0078] Further, since the cell member 410 can be supported on the cell support part 420 by the fixing part 430 and the Velcro 440, the air receiving part 411 can be effectively expanded while maintaining its horizontal position.

[0079] Furthermore, when air is discharged from the air receiving part 411, the upper surface of the air receiving part 411 can be positioned below the upper surface of the cell support part 420 and spaced apart from the lower surface of the topper, so that the topper 300 can return to a state where it is not protruded upward.

[0080] In addition, since air can flow in the left-right direction inside the air receiving part 411 through the air flow channel 412, the center and the left and right sides of the air receiving part 411 can be expanded uniformly when the air receiving part 411 is inflated.

[0081] Further, when the plurality of cell members 410 are expanded, at least some of the plurality of cell members 410 can be expanded to different heights, so that the stretching intensity can be set differently for each part of the user's body.

[0082] Although the embodiments of the present disclosure have been described as specific embodiments, this is merely an example, and the present disclosure should be construed as having the broadest scope according to the technical idea disclosed herein without being limited thereto. Those skilled in the art may implement a pattern of a shape not indicated herein by combining / substituting the disclosed embodiments, but this also does not deviate from the scope of the present disclosure. In addition, those skilled in the art may easily change or modify the disclosed embodiments based on the present specification, and it is clear that such changes or modifications also fall within the scope of the present disclosure.
