Abstract

A bed according to an embodiment may include a topper, at least one firmness adjuster provided under the topper, and a bedframe configured to have an adjustable position and to support the firmness adjuster. There may be a plurality of firmness adjusters corresponding to a plurality of areas of the bed, and each firmness adjuster may include a plurality of cushions provided in a cushion case and a drive to adjust the firmness of the plurality of cushions. The drive may change a position of a first spring relative to a second spring in each of the cushions to change a perceived firmness by a user lying on top of the topper and the firmness adjusters. A dryer may be provided under the bedframe to keep the cushions and topper dry.

First claim

What is claimed is:

1 . A bed, comprising:
a main frame; and a mattress provided on the main frame, the mattress including a plurality of cases, each case having a plurality of cushions and a motor configured to adjust a firmness of the plurality of cushions, wherein the main frame includes:
a first frame configured to support an upper body, the first frame having a plurality of first slats to support the mattress, wherein at least one case is coupled to the plurality of first slats,
a second frame configured to support a lower body, the second frame having a plurality of second slats to support the mattress, wherein at least one case is coupled to the plurality of second slats, and
a first drive configured to move the first frame relative to the second frame.

2 . The bed of claim 1 , wherein the first frame includes:
a first section; a second section hinged to the first section; and a linkage coupling the first section to the first drive.

3 . The bed of claim 2 , wherein the first drive includes a motor and a shaft, the shaft fixed to the linkage such that, when the motor rotates the shaft, at least a portion of the linkage is rotated with the shaft.

4 . The bed of claim 3 , wherein the linkage is coupled to the first section and the second section.

5 . The bed of claim 3 , wherein the linkage includes a first link coupled to the first section and a second link coupled to the first link and the shaft.

6 . The bed of claim 3 , wherein:
the first section includes a pair of first side frames, at least one first slat extending between the pair of first side frames, the second section includes a pair of second side frames, at least one first slat extending between the pair of second side frames, and the linkage includes a pair of links parallel to each other.

7 . The bed of claim 6 , wherein each link in the pair of links includes:
a pair of first links coupled to the pair of first side frames, respectively, and a pair of second links coupled to the pair of first links, respectively, and the shaft.

8 . The bed of claim 1 , further comprising a second drive configured to move the second frame relative to the first frame, wherein the second drive includes a motor and a shaft, and the second frame includes a first section, a second section hinged to the first section, and a linkage coupling the first and second sections to the shaft.

9 . The bed of claim 8 , wherein the linkage includes:
a first link coupled to the shaft, and a second link coupled to the second section and the first link.

10 . The bed of claim 9 , wherein the second link is coupled to the first link via a connection link, and at least one of the couplings between the second link and the second section, the connection link and the second link, or the connection link and the first link is a hinge coupling.

11 . The bed of claim 9 , wherein the first link is coupled to the shaft via a bracket, the bracket being fixed to the shaft and rotatably coupled to the first link.

12 . The bed of claim 11 , wherein the linkage further includes an arm link fixed to the bracket and configured to rotate with a rotation of the shaft so as to maintain contact with a bottom of the rear section.

13 . The bed of claim 9 , wherein:
the first section includes a pair of first side frames, at least one first slat extending between the pair of first side frames, the second section includes a pair of second side frames, at least one first slat extending between the pair of second side frames, the first link includes a pair of first links coupled to the shaft, and the second link includes a pair of second links coupled to the pair of second side frames and the pair of first links.

14 . The bed of claim 1 , further comprising an elastic foam layer seated on top of the mattress to be detachable.

15 . The bed of claim 1 , further comprising:
a guard configured to support the main frame and surround an outer side of the main frame, a plurality of legs to support the guard and to space the main frame apart from a floor surface.

16 . The bed of claim 15 , further comprising a first blocking sheet coupled to a front of the guard and a front of the main frame and a second blocking sheet coupled to a rear of the guard and a rear of the main frame, wherein the first and second blocking sheets cover gaps formed during a movement of the main frame.

17 . The bed of claim 1 , further comprising a dryer coupled to a bottom of the main frame, the dryer having a fan to suction air and discharge air toward the mattress.

18 . A bed, comprising:
a main frame having a plurality of slats extending in a first direction, a first frame, and a second frame adjacent to the first frame in a second direction perpendicular to the first direction, the first and second frames being rotatable relative to each other; a mattress provided on the main frame, the mattress including a plurality of cases, each case having a plurality of cushions and a drive configured to adjust a firmness of the plurality of cushions, wherein the plurality of cases are coupled to the plurality of slats; and a dryer coupled to a bottom of the main frame, the dryer having:
a fan configured to suction air,
a supply duct extending in the second direction and coupled to an outlet of the fan, and
a plurality of discharge ducts extending in the second direction, each discharge duct having an outlet through which air is discharged through the plurality of slats and toward the mattress.

19 . The bed of claim 18 , further comprising:
a plurality of legs to support the main frame and to space the dryer apart from a floor surface, and a partition provided between adjacent cases and the first and second frames to prevent collision of the cushions during a movement of the first or second frames, the partition being made of an elastic material and having a plurality of holes through which air discharged from the dryer flows, wherein the fan is configured to suction air in an axial direction and discharge air in a radial direction.

20 . A bed, comprising:
a main frame having a plurality of frames hinged to each other so as to be rotatable relative to each other, a plurality of cases coupled to the plurality of frames, each case having a plurality of cushions and a drive configured to adjust a firmness of the plurality of cushions, and at least one partition provided between adjacent of cases at a position aligned with a rotation axis of the plurality of frames so as to prevent collision between cushions during rotations of the plurality of frames, the partition being made of an elastic material and including a plurality of fins formed in an upper section.
