1 is a perspective view illustrating a structure in which a mattress core capable of adjusting a personalized sleeping environment according to an embodiment of the present invention is installed, and FIG. 2 is a plurality of mattresses and the reinforcement unit 130 shown in FIG. 1 in the housing 140. It is an exploded perspective view showing in isolation.

1 and 2 , the mattress core capable of adjusting a personalized sleeping environment according to an embodiment of the present invention includes a first mattress 110 , a second mattress 120 , a reinforcement part 130 , and a housing. 140 and an air supply module 150 .

First, it will be described as an example that the first mattress 110 and the second mattress 120 have the same structure as each other. Although not shown in the drawings, the first mattress 110 and the second mattress 120 may have different sizes or heights, or different internal structures.

Each of the mattresses 110 and 120 may be formed to be elongated along the direction in which the user lies. For example, the first mattress 110 and the second mattress 120 may be formed in a single size, and approximately horizontal*vertical length may be 1000*2000 mm. Each mattress is made of a synthetic resin including rubber, vinyl, PVC or polyurethane film and silicone, and can be provided to be deformable in volume or size. may be restricted from expanding indefinitely.

Although not shown in the drawings, each mattress may have a cell structure in which one inner chamber is divided into a plurality of regions. When such a cell structure is provided, the amount of air filling may be adjusted so that each mattress has an air pressure of a different set size for each cell area.

A reinforcing part 130 is disposed in a region between the first mattress 110 and the second mattress 120 . The reinforcing unit 130 provides a cushion similar to that of each mattress in the region between the first mattress 110 and the second mattress 120 is connected, thereby contributing to reducing the sense of heterogeneity between mattresses.

A detailed description of the reinforcing part 130 will be described later.

A housing 140 is provided outside the first mattress 110 and the second mattress 120 .

The housing 140 has an accommodating space 141 formed therein to cover the outer and rear surfaces of the first mattress 110 and the second mattress 120 , and the first mattress 110 in the accommodating space 141 . ) and the second mattress 120 may be accompanied by a function of preventing them from being pushed in the horizontal direction while being accommodated.

The housing 140 may have a structure in which air is filled, such as a mattress, or a cushion structure having a predetermined elasticity. Of course, it may be made of a structure made of an inelastic material such as a bed frame. In this embodiment, the housing 140 is made of a cushion structure having a predetermined elasticity, but is applied to a structure in which external deformation due to elastic restoration is less than that of a mattress will be described as an example.

In addition, the air supply module 150 is installed to be accommodated in the receiving space of the housing 140 , and supplies air to provide a set pressure to the first mattress 110 and the second mattress 120 . In addition, the air supply module 150 may have a function of constantly maintaining a set pressure of the air supplied to the inside of the first mattress 110 and the second mattress 120 .

Although not shown in the drawings, the air supply module 150 may be arranged to be separately accommodated outside the housing 140 .

3 is a cross-sectional view illustrating a cross section II' of the mattress shown in FIG. 1 , and FIG. 4 is a partially enlarged perspective view illustrating an enlarged area A of the mattress shown in FIG. 3 . Hereinafter, the same reference numerals as the aforementioned reference numerals denote the same components.

Referring to FIG. 3 , the first mattress 110 and the second mattress 120 are preferably disposed at the same height. In addition, it is preferable that the first mattress 110 and the second mattress 120 are disposed to be spaced apart from the inner wall of the housing 140 by a predetermined distance. For example, in the space IA in which the first mattress 110 and the second mattress 120 are spaced apart from the inner wall of the housing 140 , the outer shape of each mattress is horizontally deformed while the pressure is increased by the user. It can provide a spatial margin that can be In addition, this separation space IA can contribute to preventing noise from being generated by friction with the inner wall of the housing 140 facing the outer shape of the mattress is deformed.

In addition, the reinforcing part 130 may be disposed so that the surfaces facing each other between the first mattress 110 and the second mattress 120 are in close contact with each other. For example, the side surface of the reinforcing part 130 may be formed to have a shape corresponding to the side shape of the first mattress 110 and the second mattress 120 facing each other. That is, in contrast to the side surfaces of the first mattress 110 and the second mattress 120 protruding to form a curved surface by air pressure or a user's pressure, both sides of the reinforcing unit 130 may be formed of a concave curved surface. there is. In this way, when both sides of the reinforcing unit 130 have concave curved surfaces, the space in which the reinforcing unit 130 is spaced apart between the first mattress 110 and the second mattress 120, respectively, can be minimized, and the interior of each mattress Since the internal pressure of the reinforcing unit 130 may also be increased in response to an increase in pressure, the mattress and the reinforcing unit 130 maintain a similar pressure to each other, thereby reducing the sense of heterogeneity between the cushions.

The air supply module 150 includes a pump (or a compressor) 151 , a controller 152 and a hose 153 .

The pump 151 may create pressure in the fluid to be supplied to each mattress 110 , 120 . For example, when the pump 151 has a structure for supplying air, it can be applied as an air compressor, and when the pump 151 has a structure for supplying a liquid such as water, it can be applied as a water pump. Hereinafter, it will be described as an example that the pump 151 is applied as an air compressor for supplying air.

The controller 152 distributes and supplies the air generated from the pump 151 to each mattress, and may control the air to be supplied at different pressures to each mattress. Although not shown in the drawings, the controller 152 may be provided with an opening/closing device such as a valve for selectively transferring the air generated by the pump 151 to the hose 153 .

In addition, the controller 152 may include a communication means having at least one of a Wi-Fi or Bluetooth module so that the user can conveniently control the cushion through the mattress control application of the mobile terminal, and , or may include an infrared module to be controlled through a remote controller. That is, the user can control the pressure of each mattress or reinforcement by transmitting a control signal to the controller 152 using a mobile terminal or a remote controller.

In addition, by storing pressure set values according to the separate mode to be occupied by one person and the separation mode to be occupied by one person in the mobile terminal or the remote controller, respectively, it is possible to set a cushion corresponding to a mode change in a one-touch method.

For example, when the first mattress 110 is used by a user A weighing 80 kg and the second mattress 120 is used by a user B weighing 50 kg, the amount of air supplied to the first mattress 110 is reduced and the second mattress By increasing the amount of air supplied to 120 , the first mattress 110 and the second mattress 120 may be controlled to maintain a similar height to each other or to provide an appropriate cushion.

Of course, the controller 152 is provided with a separate pressure sensor (not shown), and when the first mattress 110 and the second mattress 120 are occupied by the user B and the user A, respectively, the air supplied to each mattress It is also possible to provide an appropriate cushion that responds to the user by increasing or decreasing the amount in the opposite direction.

Although FIG. 3 illustrates a structure in which the first mattress 110 and the second mattress 120 are connected as an example, the same control may be performed in a structure in which three or more mattresses are connected.

In addition, referring to FIG. 4 , the upper surface 131 and the lower surface 132 of the reinforcing part 130 may be made of a harder material than both side surfaces 133 . That is, the upper surface 131 and the lower surface 132 of the reinforcing part 130 are made of a harder or tougher material than the side 133 and are reinforced according to the pressure change of the first mattress 110 and the second mattress 120 . The shape of both side surfaces 133 of the part 130 may be implemented to be more easily deformed. Of course, the upper surface 131 and the lower surface 132 of the reinforcing part 130 may also be elastically deformed, but the first mattress 110 and the second mattress 120 because the degree of deformation is less than that of the side surface 133 . ), there is little deformation due to pressure change, so it is possible to relieve the sense of heterogeneity while providing a cushion when in contact with the user.

And, as shown in Figure 4, each mattress is provided with a coupling portion 160 in the portion facing each other.

For example, the coupling part 160 may be provided at one end of the outer shell of the first mattress 110 and the second mattress 120 . The coupling unit 160 includes a left first zipper 161 provided on the first mattress 110 and a right first zipper 162 provided on the second mattress 120 , and a left first zipper 161 . ) and the right first zipper 162 are engaged, the upper surfaces of the first mattress 110 and the second mattress 120 are combined into one structure. Of course, the coupling unit 160 may be implemented through various fastening structures such as Velclo, buttons, strings, etc. in addition to the zipper coupling. In addition, the area outside the edges of the first mattress 110 and the second mattress 120 may also be coupled to the housing 140 through the zipper coupling.

FIG. 5 is a cross-sectional view showing a cross section of the mattress shown in FIG. 3 along area A; FIG.

Referring to FIG. 5 , a left first zipper 161 is provided at the upper end of the first mattress 110 , and a right first zipper 161 is provided at the upper end of the second mattress 120 , and the second A left second zipper 163 may be provided at the lower end of the mattress 120 , and a right second zipper 164 may be provided at the lower end of the second mattress 120 , respectively. In this embodiment, the first zipper (160a) and the second zipper (160b) will be described as an example that is provided on both the upper surface and the lower surface of the mattress, respectively.

When the first zipper 160a and the second zipper 160b are fastened in this way, the storage or mounting of the reinforcing unit 130 in the area between the first mattress 110 and the second mattress 120 is completed, and the housing 140 . A single mattress structure can be implemented even in a structure without two.

Although not shown in the drawings, a fabric cover (not shown) may be provided on the upper surfaces of the first mattress 110 and the second mattress 120 to respectively or simultaneously cover the upper surfaces of the first zipper 160a. The fabric cover may be applied with the same material as the mattress, and provides an effect of preventing a user from directly contacting the first zipper 160a in the region between them. Of course, the fabric cover may be selectively attached so that the first zipper 160a is not easily exposed on the first mattress 110 or the second mattress 120 through a separate attachment structure.

The coupling part 160 includes a first attachment part 160c and a second attachment part 160d.

The first attachment part 160c may be detachably attached between the inner surface (or rear surface) of the first zipper 160a and the upper surface of the reinforcing part 130 . The first attachment part 160c includes a female Velcro 165 disposed on the inner surface of the first zipper 160a and a male Velcro 166 disposed on the upper surface of the reinforcing part 130 . In this embodiment, it will be described as an example that female Velcro 165 is provided on both sides of the rear surface of the first zipper 160a, and male Velcro 166 is provided on the upper surface of the reinforcing part 130 to correspond thereto. Of course, a female Velcro may be provided only on one rear surface of the first zipper 160a, or a male Velcro may be provided entirely on the upper surface of the reinforcing part 130 .

The second attachment portion 160d may be detachably attached between the inner surface (or rear surface) of the second zipper 160b and the lower surface of the reinforcing portion 130 . The second attachment part 160d includes a female Velcro 167 disposed on the inner surface of the second zipper 160b and a male Velcro 168 disposed on the upper surface of the reinforcing part 130 .

In this embodiment, as an example, female Velcro is provided on both sides of the rear surface of the second zipper 160b, and male Velcro is provided on the lower surface of the reinforcing part 130 to correspond thereto. Of course, female Velcro may be provided only on one side rear surface of the second zipper 160b, or male Velcro may be provided entirely on the lower surface of the reinforcing part 130 .

6 is an enlarged reference view illustrating various embodiments of the reinforcement unit shown in FIG. 2 .

Referring to FIG. 6( a ), the reinforcing part 130 has a substantially rectangular shape in one cross-section and provides a structure in which the inside is completely filled. Of course, the reinforcing part 130 may be made of a material that is deformable in appearance due to elastic deformation. The structure of the reinforcing part 130 may be selectively applied to a user who prefers to support the mattress relatively firmly.

Referring to FIG. 6(b) , the reinforcing part 230 is made of an elastic material having a hollow region 231 formed therein, and is deformed between the first mattress 110 and the second mattress 120 due to a change in their pressure. This provides an easy structure. This structure can be selectively applied to a user who prefers a soft mattress with relatively good cushioning because it is easy to deform outwardly compared to the structure of the reinforcing part 130 of FIG. 6( a ).

Although not shown in the drawings, in the case of the reinforcing part 230 in which the hollow region 231 is formed, air may be supplied to the hollow region 231 through the air supply module 150 of FIG. 2 . That is, when the air supply module 150 and the reinforcing unit 230 are connected, the cushion of the reinforcing unit 230 may be adjusted by filling the hollow region 231 with air at a preset pressure.

Referring to FIG. 6(c) , the reinforcing part 330 includes an elastic spring 332 in the hollow region 331 therein. Since the elastic spring 332 can adjust its elastic modulus, it can provide an elastic restoring force corresponding to the middle of FIGS. 6 (a) and 6 (b).

At this time, although not shown in the drawings, the elastic spring 332 located inside the reinforcing part 330 may be formed so that the diameter of the central region 333 is smaller than the diameter of the upper or lower portion along the height direction. This is a predetermined gap between the reinforcing part 330 and the elastic spring 332 so that the outer shape of the reinforcing part 330 can be deformed in response to the pressure change of the first mattress 110 and the second mattress 120 . There are advantages to be given.

Referring to FIG. 6( d ), an elastic spring 431 may be provided below the reinforcing part 430 in the region between them. That is, the reinforcing part 430 is disposed in the upper region in contact with the user to reduce the contact heterogeneity, and an elastic spring 431 is placed in the lower region to provide a structure for firmly supporting the reinforcing part 430 . . In addition, since the elastic spring 431 can adjust the elastic modulus, the elastic restoring force required by the user can be selected, and thus can be implemented by customizing for each user.

7 is a flowchart illustrating a process in which the user selectively controls the mattress shown in FIG. 2 or FIG. 3 .

Referring to FIG. 7 , the mattress core capable of adjusting a personalized sleeping environment according to the present invention can selectively adjust the pressures of the first mattress and the second mattress.

First, depending on how one or two people occupy the mattress, it is divided into a single mode and a separate mode, respectively.

For example, single mode can be used so that one person can occupy all of each mattress, or when two people use but prefer the same mattress pressure. In addition, the separation mode may be used when two people each occupy one mattress and the pressures of the mattresses preferred by each other are different.

If you choose the single mode, you can select the pressure of the entire mattress. As described above, it is possible to set the pressure of the entire mattress in a one-touch method by selecting a button (eg, memory 1 button) for a preset pressure in the mobile terminal or remote controller. When the pressure setting is completed, air is supplied to each mattress at the same pressure, and after determining whether the set pressure is appropriate by checking the cushion, the user can reset the pressure or end the setting.

In addition, when the separation mode is selected, the pressure of the mattress to be occupied by each user can be selected. Again, it is possible to set the pressure of each mattress in a one-touch method by selecting a button (eg, a memory 2 button) for a preset pressure in the mobile terminal or remote controller according to the separation mode. When the pressure setting is completed, air is supplied to each mattress at different pressures, and after the user checks the cushions of each mattress to determine whether the set pressure is appropriate, the pressure can be reset or the setting can be terminated.

Although not shown in the drawings, the preferred pressure of each mattress may be set and stored in a plurality of memory buttons before the mode selection step.

Therefore, according to the mattress core capable of controlling a personalized sleeping environment according to the present invention, it is possible to easily connect a plurality of mattresses, and by providing a reinforcing part in the area between each mattress, it is possible to remove the sense of heterogeneity due to the cushion, Depending on the cushion, the cushion of the reinforcing part can also be adjusted, so it can be customized. As the part is provided, there is an effect that can support a part of the user's body so as not to fall into the interspace.

In the above, specific embodiments have been shown and described to illustrate the technical spirit of the present invention, but the present invention is not limited to the same configuration and operation as the specific embodiments as described above, and various modifications do not depart from the scope of the present invention. can be carried out within Accordingly, such modifications should also be considered to fall within the scope+ of the present invention, and the scope of the present invention should be determined by the following claims.
