TECHNICAL FIELD

The present disclosure relates to a mattress assembly and furniture including the same.

BACKGROUND ART

Furniture may include chairs, beds, sofas, recliners, etc. on which users can sit or lie. Such furniture may include a mattress to support the body weight of a user lying or sitting thereon and a backrest to support the back or lower back of a user sitting on the mattress. Additionally, air cells for providing a cushion to a user, a pump for pressurizing air into the air cells, and a controller for controlling the pump may be accommodated inside a mattress.

However, a pump or a controller of conventional furniture is accommodated inside a mattress, and thus the mattress needs to be opened while being damaged when maintenance is necessary, making maintenance inconvenient and leaving traces of the openness on the exterior.

In this regard, the applicant's Korean Patent No. 10-2018-0079957, “Sleep care mattress” (Patent Document 1) discloses a mattress including an air cell body having a plurality of air cells and a controller that supplies air to control the plurality of air cells.

However, in Patent Document 1, since the controller is accommodated inside the mattress, there is a problem that the mattress needs to be disassembled and torn to open the interior of the mattress when maintenance of the controller is required. In other words, there is an inconvenience in that the controller in Patent Document 1 is not exposed to the outside without damaging the mattress.

In addition, Korean Patent No. 10-2020-0036469, “Mattress system” (Patent Document 2) by Irvine Co., Ltd. discloses a mattress system including an air pocket unit in which air pockets are divided into multiple zones, an air pump that supplies air to the air pockets, and a mattress controller that controls the air pump.

However, since the mattress controller and the air pump in Patent Document 2 are accommodated in a body forming a mattress shape, there is a problem that the body needs to be torn when maintenance of the controller and the air pump is required. In other words, there is an inconvenience in that the mattress controller and the air pump in Patent Document 2 are not exposed to the outside without damaging the body.

The air pocket unit 100 may include a plurality of air pockets 110.

The air pockets 110 may be configured to receive or discharge air pressurized by a pump 210 of the pressure regulator 200, which will be described later. Additionally, the plurality of air pockets 110 may be arranged in the horizontal direction. The plurality of air pockets 110 may have different hardness by containing or discharging air. In other words, the plurality of air pockets 110 may provide different cushions for respective parts of the user's body.

The pressure regulator 200 is accommodated in the body unit 300 and may control the pressure of the air pocket unit 100. The pressure regulator 200 may include the pump 210 and a controller 220.

The pump 210 may inject air into the air pocket unit 100. Additionally, the pump 210 may be connected to the air pocket unit 100 through a flow path through which air can flow. In other words, the pump 210 may pressurize air into the air pocket unit 100. The hardness of the air pocket unit 100 may be changed by the pump 210.

The controller 220 may control the pump 210 such that the pressure of the air pocket unit 100 is adjusted. In other words, the controller 220 may change the hardness of the air pocket unit 100 by controlling the pump 210 on the basis of the pressure of the air pocket unit 100. The controller 220 may be implemented by an arithmetic device including a microprocessor, a measuring device such as a sensor, and a memory, and the implementation method is obvious to those skilled in the art and thus further detailed description will be omitted.

For example, the topper unit 400 may be composed of multiple layers of cushion reinforcement, memory foam, etc. Additionally, the topper unit 400 may be disposed on the body unit 300. The topper unit 400 may be used to prevent or remove contamination that may occur on the body unit 300, and if the topper unit 400 is contaminated, the topper unit 400 can be replaced. Additionally, the topper unit 400 may include a first topper member 410, a second topper member 420, and a topper adhesive part 430.

The first topper member 410 may be disposed on the cover part 320. Additionally, a first embossed part 411 in which a plurality of ridges and valleys are alternately and repeatedly formed may be formed in the first topper member 410. The ridges of the first topper member 410 may be formed toward the cover part 320, and the valleys may be recessed in a direction away from the cover part 320 (for example, upward). The first embossed part 411 may be in contact with the upper surface of the cover part 320 to prevent the first topper member 410 from slipping. Additionally, the first embossed part 411 may provide cushion to the user supported by the mattress assembly 10.

The second topper member 420 may be disposed on the first topper member 410 and may be in contact with an upper surface of the first topper member 410. Additionally, a second embossed part 421 in which a plurality of ridges and valleys are alternately and repeatedly formed may be formed in the second topper member 420. The ridges of the second embossed part 421 may be formed toward the first topper member 410, and the valleys may be recessed in a direction away from the first topper member 410 (for example, upward). The second embossed part 421 may be in contact with the upper surface of the first topper member 410 to prevent the second topper member 420 from slipping. Additionally, the second embossed part 421 may provide cushion to the user supported by the mattress assembly 10.

The topper adhesive part 430 may attach the second topper member 420 to the first topper member 410. The topper adhesive part 430 may be an adhesive applied to the ridges of the second embossed part 421 such that the ridges of the second embossed part 421 are attached to the upper surface of the first topper member 410. The topper adhesive part 430 may not be applied to the valleys. In addition, since the topper adhesive part 430 is disposed on the ridges of the second embossed part 421, the valleys of the second embossed part 421 can be prevented from being attached to the first topper member 410 when the second topper member 420 is pressed by the user's weight.

The backrest 20 is disposed on one side of the mattress assembly 10 to support the user's back when the user sits on the mattress assembly 10. By using the backrest 20, the second area 322 can be disposed to face the other side of the upper edge of the frame part 310 instead of one side thereof when covering the pressure regulator 200.

Hereinafter, the operation and effects of the furniture 1 according to the embodiment of the present disclosure will be described.

Since the second area 322 of the cover part 320 of the furniture 1 according to the embodiment of the present disclosure can be moved with respect to the frame part 310, the pump 210 and the controller 220 can be easily exposed to the outside. In other words, an operator can repair the pump 210 and the controller 220 exposed to the outside without damaging the body unit 300 of the mattress assembly 10.

In addition, even if the mattress assembly 10 is moved, the pressure regulator 200, the air pocket unit 100, and the frame part 310 can be prevented from colliding with each other by the damage prevention part 340, and thus the pressure regulator 200 and the air pocket unit 100 can be prevented from being damaged.

In addition, since the topper adhesive part 430 is applied to the ridges rather than the valleys of the second embossed part 421, even if the second topper member 420 is pressed by the user's weight, the valleys of the second embossed part 421 can be prevented from being attached to the first topper member 410.

The examples of the present disclosure have been described above as specific embodiments, but these are only examples, and the present disclosure is not limited thereto, and should be construed as having the widest scope according to the technical spirit disclosed in the present specification. A person skilled in the art may combine/substitute the disclosed embodiments to implement a pattern of a shape that is not disclosed, but it also does not depart from the scope of the present disclosure. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on the present specification, and it is clear that such changes or modifications also belong to the scope of the present disclosure.
