Description

Electric mattress

Technical Field

The present invention relates to the field of mattresses, and more particularly, to an electric mattress that can improve user convenience by changing the shape of a mattress body itself to suit the body type of a user to rest.

Background

Generally, a bed is mainly of a fixed type having a fixed shape, height, and the like. In the case of such a fixed-type bed, although the prior art discloses a bed in which the inclination is implemented in such a manner as to fit a part of the body, there is a problem in that the upper height of the bed as a whole cannot be adjusted according to the height or body shape of the user. To compensate for these problems of the fixed-type beds, electric beds with adjusted heights are recently being sold in the market. The conventional electric bed for adjusting the height is not implemented to adjust the height of a part to fit the user's body shape, but is implemented only to vertically raise or lower the entire body of the user. In general, such an electric bed adopts a principle that a separate elevating device is provided at a lower side to elevate a bed frame itself or a part thereof on which a mattress main body is placed. However, the conventional height-adjustable electric beds are sold at a considerably higher price than the above-mentioned fixed beds, so that consumers have a heavy purchase burden, and the hospital beds currently used in hospitals or nursing facilities are fixed beds, which require replacement of the entire bed due to a height problem.

For example, korean patent laid-open No. 10-0732713 discloses a height adjusting apparatus for an electric bed. This issued patent discloses a height adjustment device that can be raised and lowered by electric power in such a manner as to raise and lower the height of the bed to near vertical. However, there is a problem in that only the height adjusting apparatus of the electric bed is improved and cannot be applied to the existing fixed bed. Also, korean granted Utility model No. 20-0255702 discloses an electric angle adjusting bed. The above utility model discloses a user can adjust the technique of the angle of bed easily through simple manipulation controller.

However, the above-mentioned granted patent and granted utility model disclose only that the height of the bed can be adjusted and lifted to a certain extent, and there is a problem that the whole bed including the height adjusting means must be additionally purchased and the fixed type bed used in the past must be discarded.

Therefore, a device capable of overcoming the above-mentioned drawbacks is yet to be proposed.

The first to fourth underlying materials 121 to 124 may include: a lower bed monolayer 120a; an upper bed monolayer 120b positioned at an upper side with a predetermined distance from the lower bed monolayer 120a; and a vertical filament layer 120c connecting the lower bed single layer 120a and the upper bed single layer 120 in a woven manner.

The mattress cover 110, which forms a space filling the plurality of cushion parts 120, may be made of a fabric material woven in a triple jacquard weaving method. In addition, the upper pad material 113 in the plurality of pads 120 may be a cushion foam made of a Polyurethane (PU) material. Accordingly, the pad portion 120 using the vertical filament layer 120c may be defined by the first to fourth lower pad materials 121 to 124 positioned under the upper pad material 113.

The lower bed monolayer 120a and the upper bed monolayer 120b may be respectively provided as a sandwich in which a plurality of sheets are stacked. Preferably, four layers may be overlapped in a direction spaced apart from the vertical filament layer 120 c. The middle two layers constituting the lower bed single layer 120a and the upper bed single layer 120b may be provided as a PVC sheet made of a polyvinyl chloride (PVC) material, and a PVC coating coated with liquid PVC may be provided between the PVC sheet and the vertical thread layer 120c, and an EF polymer layer may be laminated on the outer side of the PVC sheet.

The vertical filament layer 120c, which is disposed between and woven to connect the lower bed monolayer 120a and the upper bed monolayer 120b, may be woven by means of three-dimensional yarns (3D String). For example, although not shown in the drawings, a plurality of vertical filament weaving needles are provided between the lower bed single layer 120a and the upper bed single layer 120b in such a manner as to be capable of reciprocating between the lower bed single layer 120 and the upper bed single layer 120b, and the vertical filament weaving needles may weave in a zigzag form to connect the lower bed single layer 120a and the upper bed single layer 120b.

Among them, the vertical wires forming the vertical wire layer 120c are preferably core wires that substantially maintain the interval between the lower bed single layer 120a and the upper bed single layer 120b to be 50 to 500 mm. Therefore, even if air is not injected through an air packing portion (not shown in the drawings) which will be described below, the interval between the lower bed single layer 120a and the upper bed single layer 120b can be maintained at 50mm, and when air is injected through the air packing portion, the interval between the lower bed single layer 120a and the upper bed single layer 120b can be maintained within the above-described interval range according to the injection amount of air.

On the other hand, although not shown in the drawings, the motorized mattress 100 according to an embodiment of the present invention may further include an air filling part configured to selectively inject air into the inside of at least one of the first and fourth lower cushion materials 121 to 124 woven in the three-dimensional space yarn manner as described above.

In the first to fourth lower mat materials 121 to 124, air flows into the inner space, which is the space between the lower bed single layer 120a and the upper bed single layer 120b, through the air-packing portion, and thus the upper bed single layer 120b is split and expanded within the above-described interval range so as to be spaced apart from the lower bed single layer 120a, so that a comfortable elastic feeling can be given to the user.

The air filling unit may further include a pressure gauge (not shown) that measures a filling pressure (air pressure) of the air filled in the first to fourth lower pad materials 121 to 124. The operation of the air-filled portion is controlled according to the filling pressure measured by the pressure gauge and the load applying position according to the weight of the user and the change of the sleep state, so that the user can maintain the optimal sleep state.

In the electric mattress 200 according to an embodiment of the present invention, the second lower mattress material 122 of the second area 102 and the third lower mattress material 123 of the third area 103 among the plurality of mattress mats 120 provided inside the mattress cover 110 can be turned obliquely centering on the first lower mattress material 121 of the first area 101 by the activation of the electric part 200.

More specifically, when the upper body driving part 225 of the upper body actuator part 220 rotatably provided at one side of the center fixing frame part 210 in the assembly of the electric part 200 is activated, the upper body main frame 221 corresponding to the second region 102 may tilt and rotate the second under-pad material 122 in one side direction. At this time, the upper body main frame 221 may be tilted at most 90 degrees around the hinge fixing portion 226a of one side end of the center main frame 211.

In addition, when the lower body driving part 235 of the lower body actuator part 230 rotatably provided at the other side of the center frame part 210 in the assembly of the electric part 200 is activated, the lower body main frame 231 corresponding to the third region 103 may tilt and rotate the third lower cushion member 123 in the other side direction. At this time, the lower body main frame 231 may be tilted at most 90 degrees around the hinge fixing portion 236a of the other side end of the center main frame 211.

On the other hand, the fourth underlying material 124 corresponding to the fourth region 104 may be inclined and rotated in one side direction by its own weight. Further, since the rotation direction of the fourth under-pad material 124 corresponding to the fourth region 104 is not limited separately, it can be rotated by 90 degrees or more in either one direction or the other direction without being filled with air by the air filling part.

The inclination rotation of the mat materials shown in the sections (b) and (c) may be performed independently, or may be performed simultaneously or sequentially. Accordingly, the user can change the appearance of the plurality of mats 120 into a desired appearance shape, thereby resting or sleeping in a more comfortable posture.

In addition, the external shape of the electromotive mattress 100 according to an embodiment of the present invention is changed in a manner suitable for the body shape of the user, so that the user can take a rest in a more stable and comfortable posture.

Also, according to the electric mattress 100 of an embodiment of the present invention, all components of the electric part 200 are inserted into the inner space disposed at the mattress cover 110, so that it is possible to prevent a user from being injured by the electric part 200 exposed to the outside in advance.

Further, although not shown in the drawings, at least one acceleration sensor is installed inside the mattress cover 110 (preferably, in the center portion of the upper mattress material 113 in the plurality of mattress parts 120) to be able to detect whether the user is sleeping and whether there is an action during the sleeping, and thus the detected values are transmitted to the remote controller 70 provided as the internet of things control block as described above to generate data on the sleeping habits of the user.

In the motorized mattress 100 according to an embodiment of the present invention, the upper body actuator part 220 and the second lower cushion material 122 may be rotated 90 degrees in one direction with respect to the central holder part 210 and the first lower cushion material 121, and the lower body actuator part 230 and the third lower cushion material 123 may be rotated 90 degrees in the other direction with respect to the central holder part 210 and the first lower cushion material 121, thereby having an advantage of being easily accommodated in the distribution package 300.

The remaining portion of the second lower pad 122, which is not supported by the upper body actuator 220, may be further rotated in the same direction as the second lower pad 122, i.e., in the inner direction, and the fourth lower pad 124 may be further rotated in the same direction as the third lower pad 123, i.e., in the inner direction, so that it may be folded and rotated to fit the inner space of the dispensing package 300 having the hexahedral inner space.

In the electric mattress 100 according to an embodiment of the present invention, since the electric part 200 is inserted and disposed together in the inner space of the mattress cover 110, there is an advantage in that all components including the electric part 200 are received and distributed at the same time in the distribution packing box 300 as described above.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
