Description

A mattress of static pressure sensing type

The present invention relates to a static pressure-sensitive mattress, and to a static-pressure-sensitive mattress capable of adjusting a cushion by filling the inside of the mattress with air.

A commonly used mattress provides a mattress including a spring or a structure made of latex or memory foam to provide a cushion. These mattresses are usually in the form of products used by two people, but they are also made in the size for one person.

On the other hand, the mattress structure including the air cell is composed of a structure that provides a cushion by filling air in the air chamber provided therein to maintain a constant pressure.

In a mattress including such an air cell, the pressure of the air cell can be easily adjusted by filling the inside of the air cell with air according to the user's preference, and even if the cushion is degraded due to air leakage, the user can simply fill the air to maintain the original cushion. There are advantages that can be Accordingly, as the number of consumers looking for mattresses including these air cells increases, mattresses including various air cells are being developed.

Since the mattress structure including such an air cell has a limited structure to increase the size of the mattress, a method of using a plurality of mattresses facing each other is generally provided.

However, as a large error occurs in adjusting the set pressure or cushion of each mattress, a gap occurs due to the difference between the set value and the adjusted value of the mattress cushion pressure, and the cushion pressure must be readjusted several times, or due to the user's weight difference. Due to this, there is a problem that an error occurs during the leveling process.

When such a cell structure is provided, each of the mattresses 110 and 120 may adjust the amount of air filling to have different air pressures of different sizes 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 the cushions between the mattresses.

The reinforcing part 130 may be disposed so that 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 first mattress 110 and the second mattress 120 protruding to form a curved surface by the air pressure or the user's pressure, both sides of the reinforcing part 130 can be made of a concave curved surface. have.

In this way, when both sides of the reinforcing unit 130 have concave curved surfaces, the space between the reinforcing unit 130 and the first mattress 110 and the second mattress 120 can be minimized, respectively, 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.

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 occurs less due to elastic restoration than a mattress will be described as an example.

In addition, the fluid 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 fluid 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 fluid supply module 150 may be arranged to be separately accommodated outside the housing 140 .

3 is a plan view excluding the housing of the static pressure sensing type mattress shown in FIG. 1 , FIG. 4 is a partial enlarged view showing only the first mattress of the static pressure sensing type mattress shown in FIG. 3 , and FIG. 5 is shown in FIG. It is a reference diagram showing an enlarged controller of the static pressure sensing type mattress.

The first mattress 110 and the second mattress 120 are provided with inlets 111 and 121 on the side adjacent to the fluid supply module 150, respectively, and first on the side disposed far from the fluid supply module 150, respectively. An outlet (112, 212) is provided. That is, each of the mattresses (110, 120) is preferably inlet (111, 211) and the first outlet (112, 212) are located at a long distance from each other, more preferably arranged on the opposite side to each other. This is to minimize the pressure change of the air discharged through the first outlet 112 by the air pressure supplied to the inside of the mattress 110 through the inlet 111.

In FIG. 4 , the position and arrangement relationship of the inlet 111 and the outlet 112 in the first mattress 110 are shown in more detail.

When a reference line is set in the x-axis and the y-axis with respect to the inner central position C of the first mattress 110 , the first regions A1 to A4 having the same size are formed. The first mattress 110 has a second area A2 , a third area A3 , and a fourth area A4 arranged in a clockwise direction based on the first area A1 in which the injection hole 111 is provided on the side surface. In this case, the second area A2 and the third area A3 may have two adjacent side surfaces.

Accordingly, the first area A1 includes the first side S1, the second area A2 includes the second side S2 and the third side S3, and the third area A3 includes The fourth side surface S4 and the fifth side surface S5 are included, and the fourth area A4 includes the sixth side surface S6.

The first side (S1) and the second side (S2) form the lower side of the first mattress in parallel with each other, and the third side (S3) and the fourth side (S4) are the left side of the first mattress (110) The fifth side (S5) and the sixth side (S6) form the upper side of the first mattress (110).

Here, when the inlet 111 is positioned on the first side S1, it is preferable that the first outlet 112 is disposed on the fifth side S5. That is, the first side (S1) is the side disposed diagonally farthest from the fifth side (S5), and the inlet 111 and the first outlet 112 are disposed at the maximum distance from each other on the first mattress 110 . structure that can be Of course, although not shown in the drawing, if the inlet 111 is located on the second side (S2), the first outlet 112 may be disposed on the sixth side (S6).

The first mattress 110 includes a second outlet 113 . The second outlet 113 is also preferably disposed in an area adjacent to the first outlet 112 . And, it is preferable that the second outlet 113 is positioned on a different side from the fifth side S5 on which the first outlet 112 is positioned. Accordingly, the second outlet 113 will be described as being located on the fourth side S4 as an example, and may be located on other sides other than the second side S2, and the second outlet 113 may be different from each other. A plurality of each may be located on a plurality of side surfaces.

One side of the positive pressure line L1 is connected to each of the outlets 112 and 113 , and the other side of the positive pressure line L1 is connected to a pressure sensor 155 provided in the fluid supply module 150 .

In addition, the fluid supply module 150 includes a pump (or compressor) 151 , a storage chamber 152 , a valve 153 , a controller 154 , and a static pressure line L1 .

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 may be applied as an air compressor, and when the pump 151 has a structure for supplying a liquid such as water, it may be applied as a water pump. Hereinafter, the pump 151 applied as an air compressor for supplying air will be described as an example.

The storage chamber 152 may temporarily store the air generated from the pump 151 . The storage chamber 152 may absorb at least a part of the pulsation generated by the pump 151 , and may supply the stored air to the inlet 111 with a constant pressure.

The valve 153 may be a solenoid valve. The valve 153 may be opened and closed in a direction perpendicular to the direction in which air is discharged from the storage chamber toward the inlet.

The controller 154 may control the air stored in the storage chamber 152 to be supplied to each mattress 110 and 120 or to be discharged from each mattress again. In addition, the controller 154 may control each mattress to be supplied with air at the same pressure or different pressures.

The controller 154 may have a single substrate structure. For example, as shown in FIG. 5 , the controller 154 may control opening and closing of a valve 153 that is provided with a plurality of pressure sensors 155 and controls the flow of air in the inlet 111 direction.

That is, since the controller 154 has a structure in which the internal pressure of the first mattress 110 is serially connected through the static pressure line L1, more accurate pressure measurement compared to a structure in which a pressure sensor is provided between the inlet and the valve. value can be derived.

In addition, the controller 154 connects the positive pressure line L1 to connect each of the outlets 112 and 113 with the pressure sensor 155 at a location far from the inlet 111 through which air is supplied to the inside of the first mattress 110 . By doing so, even if a pressure change occurs inside the first mattress 110, it is possible to minimize the pressure change in the inner periphery of each outlet 112, 113, so that the pressure can be relatively balanced inside the static pressure line L1 effect can be expected.

Although not shown in the drawing, the controller 154 includes at least one communication means of a Wi-Fi or Bluetooth module so that the user can conveniently control the cushion through the mattress control application installed in the mobile terminal. Alternatively, it may include an infrared module to be controlled through a remote controller.

That is, the user can configure the controller to control the pressure of each mattress or reinforcement by transmitting a control signal to the controller 154 using a mobile terminal or a remote controller. In addition, the pressure setting values according to the single mode to be occupied by one person and the separate mode to be occupied by two people are stored in the mobile terminal or the remote controller, respectively, and the corresponding cushion can be set by changing the mode in a one-touch method. .

Therefore, according to the static pressure sensing type mattress according to the present invention, it is possible to connect a plurality of mattresses connected by at least two or more, and by providing a reinforcing part in an area between each mattress, it is possible to remove the sense of heterogeneity according to the cushion, and the user setting of each mattress Therefore, the internal pressure or the strength of the cushion can be adjusted to be the same or different from each other, and the inlet through which air is supplied from the fluid supply module and the static pressure line that transmits the internal pressure of the mattress to the pressure sensor are arranged farthest from each other on the mattress. Relatively accurate pressure measurement is possible even in a state where the pressure inside the mattress changes, and since the accurate pressure measurement of the mattress is made, the user can easily adjust the pressure or cushion of the mattress.

In the above, specific embodiments have been shown and described to illustrate the technical idea 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.
