Description

A mattress having a control box built-in}

The present invention relates to a mattress with a built-in control box, and to a mattress with a built-in control box in which a mattress control box that adjusts the cushion by filling the mattress with air can be installed inside the mattress structure.

Commonly used mattresses either include springs to provide cushioning, or have a structure made of latex or memory foam. These mattresses are usually designed to be used by two people, but they can also be made in sizes for one person.

In contrast, the mattress structure including air cells is structured to provide a cushion by filling an air chamber provided inside with air to maintain a certain pressure.

Mattresses containing such air cells can simply adjust the pressure of the air cells by filling the air cells to suit the user's preference, and even if the cushion deteriorates due to air leakage, the user can simply fill the air cells to maintain the original cushion. There are advantages to this. Accordingly, as the number of consumers looking for mattresses containing such air cells increases, mattresses containing various air cells are being developed.

However, in order to adjust the pressure or cushion set on the mattress, equipment such as a controller or actuator is required, but since these equipment must be installed separately outside the mattress, a problem has been raised that an installation space separate from the mattress must be provided.

Korea Registered Utility Model Publication No. 20-0388951 (registered on June 28, 2005)

The present invention is intended to solve this problem, and more specifically, its purpose is to provide a mattress built into a control box that can simultaneously install a fluid supply module that supplies fluid within the installation area of the mattress.

The present invention for achieving this purpose is a mattress; a support portion that elastically supports the lower portion of the mattress; and a fluid supply module disposed at or inside one end of the support unit to supply fluid to the mattress at a set pressure and stored in a control box. It provides a control box built-in mattress, characterized in that it includes.

The support portion may include an upper support layer supporting the lower portion of the mattress, and a lower support layer disposed below the upper support layer.

In the support part, the lower support layer is molded from a polyolefin-based polymer foam, and the upper support layer can provide a relatively soft cushioning feeling compared to the lower support layer.

The control box includes an outer case and an inner case that is selectively mounted inside the outer case and stores the fluid supply module inside, and the outer case is centered on the upper support layer with a receiving space located inside the lower support layer. It may include a flange member that supports the upper and lower surfaces, respectively, and a cover member that can be opened and closed in the downward direction of the lower support layer.

The control box may include a vibration isolation member interposed between the fluid supply module and the internal case.

The support unit has a first cut area where one end of the upper support layer is cut so that the hose can be pulled out from the side of the control box in the direction of the mattress, and one end of the lower support layer is cut to correspond to the first cut area. It may include an incised second incision area.

The fluid supply module includes a pump that generates pressure of the fluid to be supplied to the mattress inside the control box, a storage chamber that temporarily stores the pressure of the fluid generated by the pump, and an inlet provided in the mattress on the storage chamber. A controller including a valve that selectively opens and closes the connected hose, a pressure sensor that measures the pressure inside the mattress to supply or distribute fluid at a set pressure, and a connection between the first outlet provided in the mattress and the pressure sensor. It may include a static pressure line.

According to the control box built-in mattress according to the present invention,

First, since the fluid supply module can be installed within the mattress installation area, there is no need for a separate installation space for the fluid supply module.

Second, the transmission of noise or vibration can be minimized during the process of adjusting the pressure of the mattress.

Third, the control box inside the support part at the bottom of the mattress can be selectively opened and closed, making it easy to attach and detach the fluid supply module, which is advantageous in terms of maintenance.

Figure 1 is a perspective view showing a bed structure with a control box built-in mattress installed according to an embodiment of the present invention, and Figure 2 is an exploded perspective view showing the box built-in mattress shown in Figure 1 separated.

Referring to Figures 1 and 2, the control box built-in mattress 100 according to an embodiment of the present invention includes a first mattress 110, a second mattress 120, a support portion 130, and a housing 140. ) and a fluid supply module 150.

First, it will be explained as an example that the first mattress 110 and the second mattress 120 have the same structure. For example, the first mattress 110 and the second mattress 120 may be detachably connected to each other, and a separate reinforcement portion (not shown) may be provided between them and arranged symmetrically around this.

Although not shown in the drawings, the first mattress 110 and the second mattress 120 may have different sizes, heights, or internal structures, or may be applied as one mattress.

Each mattress 110, 120 may be formed to be long along the direction in which the user lies down. For example, the first mattress 110 and the second mattress 120 may be made of a single size, and the width*length may be approximately 1000*2000 mm. Each mattress is made of synthetic resin including rubber, vinyl, PVC, polyurethane film, and silicone, and can be modified in volume or size. An outer skin layer made of fiber material is laminated on the surface of each mattress, so that the volume of the mattress can be adjusted. I can limit the size from expanding indefinitely.

Although not shown in the drawings, each mattress 110, 120 may have a cell structure inside which divides one internal chamber into a plurality of areas. When such a cell structure is provided, the filling amount of air may be adjusted so that each mattress 110, 120 has a different air pressure of a set size for each cell area.

Although not shown in the drawings, a reinforcing part (not shown) may be further provided in the area between the first mattress 110 and the second mattress 120. The reinforcement part may provide a cushion similar to the cushion of each mattress in the area between the first mattress 110 and the second mattress 120, thereby contributing to reducing the feeling of heterogeneity in cushions between mattresses.

The reinforcement portion may be disposed between the first mattress 110 and the second mattress 120 so that opposing surfaces are in close contact with each other. For example, the side surface of the reinforcement portion may be formed to have a shape corresponding to the shape of the side surface of the first mattress 110 and the second mattress 120 facing each other. That is, in contrast to the fact that the first mattress 110 and the second mattress 120 protrude to form a curved side surface due to air pressure or the user's pressure, both sides of the reinforcement portion may be formed as a concave curved surface.

In this way, if both sides of the reinforcement part are made of concave curved surfaces, the separation space between the first mattress 110 and the second mattress 120 can be minimized, and in response to the increase in the internal pressure of each mattress, the reinforcement part Since the internal pressure can also be increased, the mattress and reinforcement can maintain similar pressure to each other, reducing the feeling of cushion heterogeneity in the area between them.

In addition, the support portion 130 provides a function of elastically supporting the lower portions of the first mattress 110 and the second mattress 120 from the installation surface.

The support portion 130 includes an upper support layer 130a disposed on the bottom of the first mattress 110 and the second mattress 120, and a lower support layer 130b disposed below the upper support layer 130a.

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

The housing 140 may be configured to surround each outer surface of the first mattress 110 and the second mattress 120 or cover the back thereof, but are detachable from each other.

Alternatively, the housing 140 may be provided as a single configuration in which an internal space is formed to cover each outer or rear surface of the first mattress 110 and the second mattress 120, and the first mattress ( 110) and the second mattress 120 may be accommodated and have a function of preventing them from being pushed in the horizontal direction.

The housing 140 may be made of a structure filled with air, like a mattress, or may be made of a cushion structure with a certain elasticity, or may be made of a prefabricated structure that is detachable from each other. Of course, it may be made of a non-elastic material, such as a bed frame structure. In this embodiment, the housing 140 is made of a cushion structure with a certain elasticity, but the external deformation due to elasticity restoration is less than that of a mattress.

In addition, the fluid supply module 150 is installed in the lower space of the first mattress and the second mattress in the inner space of the housing 140 and supplies air to provide a set pressure to the first mattress 110 and the second mattress 120. supply. Additionally, the fluid supply module 150 may have the function of maintaining a constant set pressure of the air supplied inside the first mattress 110 and the second mattress 120.

101 and 102, which are not described in FIG. 2, may be topper mattresses provided to integrally connect the upper portions of the first mattress 110 and the second mattress 120. Topper mattresses can be optionally provided in one or multiple pieces.

FIG. 3 is a reference diagram showing the fluid supply module and control box of the control box built-in mattress shown in FIG. 1 separated, and FIG. 4 is a block diagram showing the internal configuration of the fluid supply module of the control box built-in mattress shown in FIG. 3. am.

Referring to Figures 3 and 4, the control box built-in mattress 100 includes a control box 160 inside the support portion 130. And, the control box 160 includes an outer case 160a and an inner case 160b.

The inner case 160b can be detachably stored inside the outer case 160a.

Here, the outer case (160a) protects the inner case (160b) from external shock applied from the mattress and stably connects the static pressure line (L1) and hose (L2) connected between the mattress and the fluid supply module 150. Provides protection.

The outer case 160a has a receiving space 161 in which the inner case 160b is installed, located on the lower support layer 130b, and a flange member 162 is provided in the upper area to support the upper and lower surfaces of the upper support layer 130a. By combining them, it is possible to achieve a step-by-step balance of the mattress cushion. In addition, the outer case 160a is provided with a cover member 163 so that it can be opened and closed in the downward direction of the lower support layer 130b. The cover member 163 can selectively open and close the receiving space of the external case 160a. For example, when maintenance of the inner case 160b or the fluid supply module 150 is required from the outer case 160a, the control box 160 is opened by opening the cover member 163 without dismantling the mattress, and the fluid supply module ( 150) can be easily removed and maintenance and assembly can be simplified.

A fluid supply module 150 is disposed inside the inner case 160b. Additionally, a vibration isolation member (see FIG. 6, 164) may be provided between the areas where the fluid supply module 150 is installed on the inner case 160b. For example, the vibration isolation member 164 may be made of a vibration isolation pad or a damper structure that absorbs noise or vibration.

And, 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 generate pressure of fluid to be supplied to each mattress (110, 120). For example, if the pump 151 has a structure that supplies air, it can be applied as an air compressor, and if it has a structure that supplies liquid such as water, it can be applied as a water pump. Hereinafter, it will be explained as an example that the pump 151 is applied as an air compressor that supplies air.

The storage chamber 152 may temporarily store air generated from the pump 151. The storage chamber 152 can absorb at least part of the pulsation generated by the pump 151 and supply the stored air at a constant pressure in the direction of the inlet formed in each mattress.

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 152 toward the inlet.

The controller 154 can control the air stored inside the storage chamber 152 to be supplied to each mattress 110 and 120 or to be discharged from each mattress. Additionally, the controller 154 can control air to be supplied to each mattress at the same pressure or different pressures.

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

That is, since the controller 154 has a structure in which the internal pressure of the first mattress 110 is connected in series through the static pressure line (L1), it measures pressure more accurately than a structure in which a pressure sensor is provided between the inlet and the valve. The value can be derived.

In addition, the controller 154 connects the static pressure line (L1) to connect each outlet to the pressure sensor 155 at a location far from the inlet through which air is supplied to the inside of the first mattress 110. Even if a pressure change occurs, the pressure change around the inside of each outlet (112, 113) can be minimized, so the effect of maintaining relative pressure balance within the static pressure line (L1) can be expected.

Although not shown in the drawing, the controller 154 includes at least one communication means (156) of a Wi-Fi or Bluetooth module so that the user can conveniently control the cushion through a mattress control application installed on the mobile terminal. ), or it may include an infrared module so that it can be controlled through a remote controller.

That is, the user can configure the controller 154 to control the pressure of each mattress or reinforcement section by transmitting a control signal to the controller 154 using a mobile terminal or remote controller. In addition, the mobile terminal or remote controller stores the pressure settings according to the single mode for one person to occupy the mattress and the separate mode for two people to occupy the mattress, and the corresponding cushion can be set by changing the mode with one touch. .

Figure 5 is a partial enlarged view showing a portion of the support portion of the control box built-in mattress shown in Figure 2, and Figure 6 is a cross-sectional view showing the control box of the control box built-in mattress shown in Figure 1 in an open state. .

Referring to Figures 5 and 6, the upper support layer 130a can be formed by heat-sealing a plurality of soft polyurethane foam sheets. Accordingly, the upper support layer 130a may have relatively less elastic restoring force than the lower support layer 130b, or may be made of a material that provides a soft cushioning feeling. In addition, the upper support layer 130a supports the original cushioning of each mattress so that it does not deteriorate, and can be applied as a replaceable structure.

The lower support layer 130b can be formed by heat-sealing polyolefin-based polymer foam in a plurality of layers in the form of a sheet. Accordingly, the lower support layer 130b has a relatively superior support force than the upper support layer 130a and can firmly protect the control box and fluid supply module to be installed therein.

If the lower support layer is made of general soft foam, soft polyurethane foam, or soft slab foam, it is too soft to properly support the control box.

Additionally, if the lower support layer is made of a material that is too hard, such as plastic, resin, wood, or metal, vibration and noise generated from the control box may be transmitted and cause discomfort to the user.

Therefore, it is desirable to use polyolefin-based polymer foam in the lower support layer 130b to obtain a certain degree of support and vibration/noise absorption.

In addition, the upper support layer 130a can be coupled to the control box 160, and can prevent noise or vibration generated from the fluid supply module 150 mounted inside the control box 160 from being transmitted toward the mattress. there is.

The upper support layer 130a includes a first cut area 131 so that the static pressure line L1 and the hose L2 can be extracted from the side of the control box 160 toward the mattress. Additionally, the lower support layer 130b includes a second cut area 132 corresponding to the first cut area 131. The first incision area 131 and the second incision area 132 may be arranged to overlap each other in the vertical direction.

The upper support layer 130a is penetrated along the thickness direction to form a first mounting area 133 where the flange member 162 of the control box 160 is installed, and the lower support layer 130b is a first mounting area 133. A second mounting area 134 may be formed in which the control box 160 is installed to be inserted or recessed at a position corresponding to .

Additionally, the fluid supply module 150 is preferably disposed adjacent to one end along the longitudinal direction of each mattress on the support portion 130. Although not shown in the drawing, it is more preferable that the fluid supply module 150 is disposed in the opposite direction to the head area of the mattress. For example, when the user lies down with his head facing the head area, the fluid supply module 150 and the first incision area 131, second incision area 132, and A first mounting area 133 and a second mounting area 134 may be disposed. This is so that the user can feel the minimum noise or vibration generated from the fluid supply module 150.

Therefore, according to the control box built-in mattress according to the present invention, it is possible to connect a plurality of mattresses connected in at least two or more ways, and by providing a reinforcing part in the area between each mattress, the feeling of heterogeneity due to the cushion can be eliminated, and the user of each mattress can Depending on the setting, the internal pressure or cushion strength can be adjusted equally or differently, and the inlet where 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 placed at the furthest distance from each other on the mattress. Therefore, relatively accurate pressure measurement is possible even when the pressure inside the mattress changes, and by accurately measuring the pressure of the mattress, 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 may be made without departing from the scope of the present invention. It can be carried out within. Accordingly, such modifications should also be considered as falling within the scope+ of the present invention, and the scope of the present invention should be determined by the claims described below.
