Description

bed

[0001] The present invention relates to a bed.

[0002] Typically, beds can be provided as standard beds with a fixed length, or as extendable beds with adjustable lengths. Extendable beds can be extended by rotating the leg rests, which support the user's legs, around the upper body rest, or by sliding them forward and backward.

[0003] Meanwhile, massage devices provide physical stimulation or pressure to the entire body or specific areas, promoting blood circulation and facilitating metabolism. Furthermore, massage devices apply pressure to muscles, relieving tension and thus relieving physical and mental fatigue, and contributing to fatigue recovery, disease prevention, and beauty. Conventional massage beds, which incorporate massage devices, are sometimes provided. These beds can massage the user's body while lying down or sitting.

[0004] In this regard, applicant Jeong Chan-in's Korean Patent Publication No. 10-2003-0087599, "Multifunctional bed with massage device" (Patent Document 1), discloses a bed equipped with a massage device so that a user can receive a massage function while lying down.

[0005] However, the multifunctional bed with a massage device of Patent Document 1 is composed of a single frame, so the bed must always be unfolded. In other words, the multifunctional bed of Patent Document 1 has the problem of taking up a lot of space when the user is not using the massage device, as well as when the bed is unfolded.

[0006] In addition, with regard to an expandable bed, Korean Patent Publication No. 10-1206967 "Sliding-type thermal therapy device" (Patent Document 2) of the applicant, Seragem Co., Ltd., discloses a thermal therapy device that provides a therapeutic function to a user and a lower bed member that can slide relative to the body to cover the thermal therapy device. The thermal therapy device of Patent Document 2 is configured to have a reduced volume as the lower bed member slides.

[0007] However, in the sliding type thermal therapy device of Patent Document 2, when the lower bed member is deployed by sliding horizontally along the guide groove formed in the body, the guide groove is exposed to the outside, so that parts of the user's body or objects, etc., may get caught in the guide groove or foreign substances may be inserted. In other words, when the lower bed member is deployed by sliding, damage may occur due to the guide groove exposed to the outside.

[0008] One embodiment of the present invention was invented with the above background in mind, and aims to provide a bed capable of limiting the link accommodation space in which a link bar is accommodated from being exposed to the outside.

[0009] According to one embodiment of the present invention, a bed comprises: a main body; a main frame supporting the main body; and a subframe provided to be relatively movable with respect to the main frame so as to be in a first state in which a center portion thereof is disposed above the main frame so as to overlap the main frame or in a second state in which the center portion thereof is disposed further forward than the first state; and a link bar connecting the subframe to the main frame so as to be relatively movable, wherein the main body includes a link accommodation space in which the link bar is accommodated when the subframe is in the first state, and a cover assembly configured to be rotatable about an axis parallel to a longitudinal direction of the main body, so as to open the link accommodation space when the subframe is in the first state, and to close the link accommodation space when the subframe is in the second state.

[0010] In addition, the cover assembly may include a link cover that closes or opens the link receiving space; an elastic member that applies elastic force to the link cover; and a rotation bracket that rotates the link cover against the elastic force of the elastic member by the pressure of the subframe.

[0011] In addition, the link cover may include a cover part; a cover shaft part that provides a rotation axis so that the cover part can rotate; and a cover support part that is formed to be curved at the lower portion of the cover part so that the cover part opens the link receiving space by the pressure of the rotation bracket.

[0012] In addition, the rotating bracket may include a bracket shaft portion; a bracket support portion that is formed protrudingly on one side of the bracket shaft portion and rotates about the bracket shaft portion as an axis by the pressure of the subframe when the subframe is placed in the second state; and a bracket push portion that is formed protrudingly on the other side of the bracket shaft portion and pushes the link cover when the bracket support portion is pressed by the subframe.

[0013] In addition, a bed according to one embodiment of the present invention includes a bed frame including a main body; a main frame supporting the main body; and a subframe provided to be movable relative to the main frame so as to be in a first state in which a center portion thereof is disposed above the main frame so as to overlap the main frame or a second state in which the center portion thereof is disposed further forward than the first state; and a link bar that connects the subframe to the main frame so as to be movable relative to the main frame, wherein the main body includes a link receiving space in which the link bar is received when the subframe is placed in the first state, and the main body may further include a shutter assembly configured to be slidably moved, and to close at least a portion of the link receiving space when the subframe is switched between the first state and the second state.

[0014] In addition, the shutter assembly includes a guide rail arranged in the link receiving space; a sliding shutter configured to be slidably moved along the guide rail; and the sliding shutter can slide along the guide rail in conjunction with the link bar when the link bar is rotated.

[0015] In addition, the sliding shutter may include a first sliding shutter configured to be slidably moved along the guide rail; and a second sliding shutter configured to be slidably moved along the first sliding shutter.

[0016] Additionally, the shutter assembly may include a plurality of rollers that contact the link bar so that the sliding shutter slides in conjunction with the rotation of the link bar while the link bar rotates.

[0017] In addition, the second sliding shutter may include a second shutter portion movable along the guide rail and the first sliding shutter; a second rail surface portion providing a path along which the first sliding shutter can slide to the second shutter portion; and a second stopper configured to engage the first sliding shutter so that the first sliding shutter can slide together with the first sliding shutter in at least a portion of the section.

[0018] In addition, the link bar includes a main link; and a sub link that is spaced apart from the main link and rotatably connects the sub frame to the main frame, the main link includes a main link bending portion having a curved shape, and the main link bending portion can be disposed on an upper portion of the main frame when the sub frame is in the second state and can be disposed on a lower portion of the main frame when the sub frame is in the first state.

[0019] One embodiment of the present invention has the effect of limiting exposure of the link bar to the outside or allowing rotational movement of the link bar by closing or opening a link receiving space in which the link bar is received when the subframe rotates and moves relative to the main frame.

[0020] In addition, one embodiment of the present invention has the effect of preventing a part of the user's body or an object from being caught or inserted into the link receiving space by closing the link receiving space through rotation of the link cover due to the pressure of the subframe when the subframe rotates and moves relative to the main frame.

[0021] In addition, one embodiment of the present invention has the effect of preventing the exposure of a gap in which a part of the user's body or an object may be caught or inserted into the link receiving space when the subframe rotates and moves relative to the main frame, by sliding the sliding shutter in conjunction with the link bar.

[0022] In addition, one embodiment of the present invention has the effect that when the subframe rotates and moves relative to the mainframe, the subframe can be placed in a first state in which it overlaps the upper side of the mainframe, and a second state in which the subframe is positioned further forward than the first state, so that the subframe can be overlapped or unfolded in an overlapping state with respect to the mainframe.

[0023] In addition, one embodiment of the present invention has the effect of preventing friction between the subframe and the mainframe when the subframe rotates and moves relative to the mainframe, thereby preventing noise and damage caused by friction.

[0024] In addition, one embodiment of the present invention has the effect that the sublink and the main link can stably induce relative movement of the subframe with respect to the mainframe by rotatably connecting the sublink and the main link between the mainframe and the subframe for relative movement of the subframe with respect to the mainframe.

[0025] In addition, one embodiment of the present invention has the effect of connecting the main frame and the sub frame through the main link and the sub link formed to form a predetermined angle smaller than the horizontal angle, so that when the sub frame rotates and moves relative to the main frame, the sub frame can be placed in a first state in which it overlaps the upper side of the main frame and a second state in which the sub frame is placed forward of the first state.

[0040] Hereinafter, specific embodiments for implementing the idea of ​​the present invention will be described in detail with reference to the drawings.

[0041] In addition, when explaining the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description is omitted.

[0042] The terminology used herein is intended solely to describe specific embodiments and is not intended to limit the invention. Singular expressions include plural expressions unless the context clearly dictates otherwise.

[0043] Additionally, please note that the terms "upper side," "lower side," and "side" in this specification are based on the illustrations in the drawings and may be expressed differently if the orientation of the subject changes. For the same reason, some components in the attached drawings are exaggerated, omitted, or schematically depicted, and the sizes of each component do not fully reflect the actual size.

[0044] The term "comprising" as used in the specification means specifying a particular characteristic, region, integer, step, operation, element and / or component, but does not exclude the presence or addition of other particular characteristics, regions, integers, steps, operations, elements, components and / or groups.

[0045] Hereinafter, a bed according to one embodiment of the present invention will be described with reference to the drawings.

[0046] Referring to FIGS. 1 to 9, in the first embodiment of the present invention, the bed (1) may be provided as an expandable bed capable of changing length. This bed (1) may include a main body (100), a bed frame (200), and a link bar (300).

[0047] The main body (100) can support a bed frame (200), a bed frame (200), and a link bar (300). The main body (100) can include an upper mattress on which the user's upper body can lie and a lower mattress on which the user's legs can be placed. In addition, the main body (100) can include a link receiving space (110) and a cover assembly (120).

[0048] The link receiving space (110) may be a space through which at least a portion of the link bar (300) passes while the subframe (220) described below transitions between a first state and a second state. The link receiving space (110) may receive the link bar (300) when the subframe (220) is placed in the first state. In the present embodiment, the first state may be a state in which the center of the subframe (220) is positioned above the main frame (210) so as to overlap with the main frame (210), and the second state may be a state in which the center of the subframe (220) is positioned further forward than in the first state. These first and second states may be referred to as an overlapping state and an extended state, respectively.

[0049] The cover assembly (120) can selectively close or open the link receiving space (110) when the subframe (220) moves relative to the main frame (210). For example, the cover assembly (120) can open the link receiving space (110) when the subframe (220) is in a first state, and can close the link receiving space (110) when the subframe (220) is in a second state. The cover assembly (120) can be configured to rotate around an axis parallel to the longitudinal direction of the main body (100). The cover assembly (120) can include a link cover (121), an elastic member (122), and a rotation bracket (123).

[0050] The link cover (121) can prevent a part of the user's body or an object from being caught or inserted into the link receiving space (110) by closing the link receiving space (110). In addition, the link cover (121) can provide a space through which at least a part of the link bar (300) passes when the subframe (220) moves between the first state and the second state by opening the link receiving space (110).

[0051] The link cover (121) may include a cover part (121-1), a cover shaft part (121-2), and a cover support part (121-3). The cover part (121-1) may be a door that can close or open the link receiving space (110). The cover part (121-1) may be rotated with the cover shaft part (121-2) as a rotation axis. The cover shaft part (121-2) and the cover support part (121-3) may be formed at the lower portion of the cover part (121-1). The cover shaft part (121-2) may be provided as the rotation axis of the cover part (121-1). The cover shaft part (121-2) may be formed at one side of the lower portion of the cover part (121-1), thereby allowing the cover part (121-1) to rotate eccentrically. The cover support portion (121-3) may be formed to be curved on one side of the lower portion of the cover piece portion (121-1). When the cover support portion (121-3) is pressed by the rotation bracket (123), the cover piece portion (121-1) may open the link receiving space (110).

[0052] The elastic member (122) can apply elastic force to the link cover (121). When the pressure by the rotating bracket (123) is released, the elastic member (122) can be restored to its original shape, thereby providing elastic force to the link cover (121) that can move the link cover (121) to its original position.

[0053] The rotating bracket (123) can selectively rotate the link cover (121). For example, when the rotating bracket (123) is pressed by the subframe (220), the link cover (121) can be rotated against the elastic force of the elastic member (122). The rotating bracket (123) can be rotatably arranged on the main frame (210) and can maintain a state in which it receives elastic force from the elastic member (122). The rotating bracket (123) can include a bracket shaft portion (123-1), a bracket support portion (123-2), and a bracket push portion (123-3). The bracket shaft portion (123-1) can be a rotation axis of the rotating bracket (123).

[0054] The bracket shaft portion (123-1) may be arranged between the bracket support portion (123-2) and the bracket push portion (123-3). The bracket support portion (123-2) may be formed to protrude on one side of the bracket shaft portion (123-1). The bracket shaft portion (123-1) may be arranged between the bracket support portion (123-2) and the bracket push portion (123-3). When the bracket support portion (123-2) is pressed by the subframe (220), the bracket shaft portion (123-1) may transmit the pressing force of the subframe (220) in a seesaw shape from the bracket support portion (123-2) to the bracket push portion (123-3).

[0055] The bracket support portion (123-2) may be formed to protrude on one side of the bracket shaft portion (123-1). The bracket support portion (123-2) may be arranged to extend in the same direction as the bracket push portion (123-3) with the bracket shaft portion (123-1) interposed therebetween. When the subframe (220) is placed in the second state, the bracket support portion (123-2) may be rotated around the bracket shaft portion (123-1) as the rotation axis by the pressure of the subframe (220).

[0056] The bracket push unit (123-3) can selectively push the link cover (121). For example, when the bracket support unit (123-2) is pressed by the subframe (220), the bracket push unit (123-3) can push the link cover (121) by the rotation of the bracket shaft unit (123-1). The bracket push unit (123-3) can be formed to protrude on the other side of the bracket shaft unit (123-1). The bracket push unit (123-3) can be arranged to extend in the same direction as the bracket support unit (123-2) with the bracket shaft unit (123-1) therebetween.

[0057] The bed frame (200) can support an upper mattress and a lower mattress. The bed frame (200) can also support a massage module. The bed frame (200) can include a main frame (210) and a subframe (220).

[0058] The main frame (210) can support an upper mattress that can support the user's upper body. The main frame (210) can be connected to the subframe (220) via the main link (310) and the sublink (320). The ends of the main link (310) and the sublink (320) can be rotatably connected to the lower part of the main frame (210).

[0059] The subframe (220) can support a lower mattress on which the user's legs can be placed. The subframe (220) can be rotated and moved relative to the main frame (210). When viewed from the side, the subframe (220) can be formed to extend and bend from a horizontal direction to a vertical direction. The subframe (220) can be rotatably connected to the main frame (210) via a main link (310) and a sub link (320).

[0060] The subframe (220) may be provided to be relatively movable with respect to the mainframe (210). For example, when the subframe (220) is moved by the rotation of the main link (310) and the sublink (320), the subframe (220) may be placed in a first state or a second state. The first state may be a state in which the center of the subframe (220) is positioned above the mainframe (210) so as to overlap with the mainframe (210), and the second state may be a state in which the center of the subframe (220) is positioned further forward than in the first state. These first and second states may be referred to as an overlapping state and an extended state, respectively.

[0061] A link bar (300) can be connected between the main frame (210) and the sub frame (220) to enable relative movement of the sub frame (220) with respect to the main frame (210). The link bar (300) can include a main link (310), a sub link (320), a main sink bar (330), and a sub sink bar (340).

[0062] The main link (310) can connect the subframe (220) to the front portion of the main frame (210) so as to be relatively movable. The main link (310) can be bent to form a predetermined angle that is greater than a right angle and less than a flat angle. The main link (310) can be provided in multiple pieces, and the multiple main links (310) can include a left main link (310a) arranged on the left side of the main frame (210) and a right main link (310b) arranged on the right side of the main frame (210). The left main link (310a) and the right main link (310b) can include a first main link portion (311), a second main link portion (312), and a main link bend portion (313), respectively. Meanwhile, in the drawing according to the present embodiment, the left main link (310a) and the right main link (310b) are depicted as having the same shape, but the spirit of the present invention is not necessarily limited thereto, and the left main link (310a) and the right main link (310b) may have different shapes.

[0063] The first main link portion (311) can be rotatably connected to the main frame (210). The first main link portion (311) can extend in a different direction from the second main link portion (312). The first main link portion (311) can be connected to the second main link portion (312) to form a predetermined angle with each other. For example, the first main link portion (311) can be connected to the second main link portion (312) in the front-rear direction through the main link bending portion (313) so that the angle formed with the second main link portion (312) is less than a parallel angle and greater than a right angle. The first main link portion (311) can extend forward when the subframe (220) is placed in the second state. When the subframe (220) is placed in the second state, the upper side of the first main link portion (311) may be arranged to be inclined toward the front so that the first sublink portion (321) of the sublink (320) forms a third angle smaller than the first and second angles described later with respect to an imaginary line extending in the vertical direction.

[0064] The second main link portion (312) can be rotatably connected to the subframe (220). The second main link portion (312) can extend in a different direction from the first main link portion (311). The second main link portion (312) can be connected to the first main link portion (311) through the main link bend portion (313) so as to form an angle that is less than a parallel angle and greater than a right angle. The second main link portion (312) can be arranged parallel to the horizontal direction when the subframe (220) is in the second state.

[0065] The main link bending portion (313) can be bent and connected between the first main link portion (311) and the second main link portion (312). The main link bending portion (313) can have a curved shape with a curvature. When the subframe (220) is placed in the second state, the main link bending portion (313) can be placed on the upper portion of the main frame (210), and when the subframe (220) is placed in the first state, the main link bending portion (313) can be placed on the lower portion of the main frame (210). Although the main link bending portion (313) is illustrated in the drawing according to the present embodiment, the main link bending portion (313) can also be omitted. In other words, the first main link portion (311) and the second main link portion (312) can also be directly connected while forming a corner.

[0066] The sub-link (320) can be connected to the rear portion of the main frame (210) so as to be relatively movable. The sub-link (320) can be spaced apart from the main link (310) and rotatably connected to the main frame (210) and the sub-frame (220). When the main link (310) rotates, the sub-link (320) can rotate in the same direction as the main link (310). Depending on the position where the sub-link (320) is arranged in the main frame (210), the sub-link (320) can include a left sub-link (320a) arranged on the left side of the main frame (210) and a right sub-link (320b) arranged on the right side of the main frame (210). Each of the left sub-link (320a) and the right sub-link (320b) can include a first sub-link portion (321), a second sub-link portion (322), and a sub-link bending portion (323).

[0067] The first sub-link unit (321) can be rotatably connected to the main frame (210). The first sub-link unit (321) can extend in a different direction from the second sub-link unit (322). The first sub-link unit (321) can have a longer length than the second sub-link unit (322), the first main link unit (311), and the second main link unit (312). The first sub-link unit (321) can be connected to the second sub-link unit (322) to form a predetermined angle with respect to each other. For example, the first sub-link unit (321) can be connected to the second sub-link unit (322) to form a predetermined angle that is greater than a right angle and less than a parallel angle. When the sub-frame (220) is placed in the second state, the first sub-link unit (321) can be arranged so that its upper side is inclined forward so as to form a first predetermined angle with respect to an imaginary line extending in the vertical direction.

[0068] The second sub-link unit (322) may be rotatably connected to the sub-frame (220). The second sub-link unit (322) may extend in a different direction from the first sub-link unit (321). The second sub-link unit (322) may be connected to the first sub-link unit (321) to form a predetermined angle that is greater than a right angle and less than a parallel angle. When the sub-frame (220) is in the second state, the second sub-link unit (322) may be arranged with its upper side tilted forward to form a second angle that is smaller than the first angle described above with respect to an imaginary line extending in the vertical direction.

[0069] The sub-link bending portion (323) can be bent and connected between the first sub-link portion (321) and the second sub-link portion (322) so that the first sub-link portion (321) and the second sub-link portion (322) are arranged to be misaligned from each other. The sub-link bending portion (323) can have a curved shape. When the sub-frame (220) is placed in the second state, the sub-link bending portion (323) can be arranged on the upper part of the main frame (210), and when the sub-frame (220) is placed in the first state, the sub-link bending portion (323) can be arranged on the upper part of the main frame (210). Although the sub-link bending portion (323) is illustrated in the drawing according to the present embodiment, the sub-link bending portion (323) can also be omitted. In other words, the first sub-link portion (321) and the second sub-link portion (322) can also be directly connected to form a corner.

[0070] The main sink bar (330) can be connected to the left main link (310a) and the right main link (310b). For example, both ends of the main sink bar (330) can be connected to the lower portion of the left main link (310a) and the lower portion of the right main link (310b). When both ends of the left main link (310a) and the right main link (310b) are respectively connected to the main frame (210) and the subframe (220), the both ends of the main sink bar (330) are connected to the lower portion of the left main link (310a) and the lower portion of the right main link (310b), thereby preventing the subframe (220) from being twisted when the subframe (220) moves relative to the main frame (210).

[0071] The sub sink bar (340) can be connected to the left sub link (320a) and the right sub link (320b). For example, both ends of the sub sink bar (340) can be connected to the lower portion of the left sub link (320a) and the lower portion of the right sub link (320b). When both ends of the left sub link (320a) and the right sub link (320b) are connected to the main frame (210) and the sub frame (220), respectively, the both ends of the sub sink bar (340) are connected to the lower portion of the left sub link (320a) and the lower portion of the right sub link (320b), thereby preventing the sub frame (220) from being twisted when the sub frame (220) moves relative to the main frame (210).

[0072] Meanwhile, in addition to these configurations, a bed (1) according to a second embodiment of the present invention may be provided. The second embodiment of the present invention will be described with reference to FIGS. 10 to 14. In describing the second embodiment, compared to the first embodiment described above, there is a difference in that the main body (100) includes a shutter assembly (130). Therefore, the following description will focus on the differences, and the same descriptions and drawing references will be used.

[0073] Referring to FIGS. 10 to 14, in the second embodiment of the present invention, in the bed (1), the shutter assembly (130) can selectively close at least a portion of the link receiving space (110). For example, when the subframe (220) switches between the first state and the second state, the shutter assembly (130) can close at least a portion of the link receiving space (110). The shutter assembly (130) can be arranged to slide along the longitudinal direction of the main frame (210). The shutter assembly (130) can include a guide rail (131), a sliding shutter (132), and a roller (133).

[0074] The guide rail (131) can provide a movement path of the sliding shutter (132) along which the sliding shutter (132) can move. The guide rail (131) can extend along the length of the main frame (210) so as to be parallel to the link receiving space (110).

[0075] The sliding shutter (132) may be arranged to be able to slide along the guide rail (131). When the link bar (300) rotates, the sliding shutter (132) may be linked to the link bar (300) and slide along the guide rail (131). The sliding shutter (132) may include a first sliding shutter (132-1) and a second sliding shutter (133-2).

[0076] The first sliding shutter (132-1) can slide along the guide rail (131) in conjunction with the rotation of the link bar (300). The first sliding shutter (132-1) can include a second shutter portion (132-11), a first rail surface portion (132-12), and a first sliding groove portion (132-13). The first shutter portion (131-21) can move along the guide rail (131). The first shutter portion (132-11) can contact the outer surface of the guide rail (131) through the first rail surface portion (132-12). The first shutter portion (132-11) can move along the guide rail (131) through a roller. The first rail surface portion (132-12) can provide a rail surface that can slide on the outer surface of the guide rail (131). The first sliding groove (132-13) can provide a slit in which the second sliding shutter (132-2) can be caught in at least a portion of the first sliding shutter (132-1). The second stopper portion (132-23) of the second sliding shutter (132-2) can be maintained inserted into the first sliding groove (132-13).

[0077] The second sliding shutter (132-2) may be arranged to be able to slide along the guide rail (131) and the first sliding shutter (132-1). The second sliding shutter (132-2) may include a second shutter portion (132-21), a second rail surface portion (132-22), and a second stopper portion (132-23). ​​The second shutter portion (132-21) may be a movable body that may move along the guide rail (131) and the first sliding shutter (132-1). The second shutter portion (132-21) may contact the outer surface of the first sliding shutter (132-1) through the second rail surface portion (132-22). The second rail surface portion (132-22) may provide the second shutter portion (132-21) with a path along which the first sliding shutter (132-1) may slide. The second stopper portion (132-23) may be formed to protrude from the second shutter portion (132-21) so that it can be moved while being caught in the first sliding groove portion (132-13) of the first sliding shutter (132-1). The second stopper portion (132-23) may be caught in the first sliding shutter (132-1) in at least a portion of the first sliding shutter (132-1) and may be moved together with the first sliding shutter (132-1).

[0078] The roller (133) can be brought into contact with the link bar (300) so that when the link bar (300) rotates, the sliding shutter (132) moves along the guide rail (131) in conjunction with the rotation of the link bar (300). The rollers (133) may be provided in multiples. For example, the rollers (133) may be provided as a pair spaced apart from each other with the link bar (300) in between.

[0079] Hereinafter, the operation and effect of the bed according to one embodiment of the present invention will be described.

[0080] Referring back to FIGS. 1 and 2, the subframe (220) can be placed in a first state in which its center overlaps with the mainframe (210). When the subframe (220) is placed in the first state, the link bar (300) can be accommodated in the link accommodation space (110). In the first state, the subframe (220) is placed on the upper side of the mainframe (210) so that its center overlaps with the mainframe (210), so that the bed (1) can be in a small volume state that is easy to store and can be in an unusable state.

[0081] Referring back to FIGS. 3 and 4, the center of the subframe (220) may be positioned above the mainframe (210) to transform from the first state to the second state. When the subframe (220) transforms from the first state to the second state, the left main link (310a) and the right main link (310b) may rotate and move relative to each other in conjunction with the left sublink (320a) and the right sublink (320b).

[0082] Referring again to FIGS. 5 to 7, the subframe (220) can be placed in a second state in which the mainframe (210) and the subframe (220) are flat. When the subframe (220) is placed in the second state, the link cover (121) due to the pressure of the subframe (220) can close the link receiving space (110). Since the mainframe (210) and the subframe (220) are placed in a flat state in the second state, the bed (1) can be in a state in which it can be used by a user.

[0083] Meanwhile, the bed (1) according to one embodiment of the present invention can limit the link bar (300) from being exposed to the outside by closing the link receiving space (110) in which the link bar (300) is received when the subframe (220) rotates and moves relative to the main frame (210), and can allow the rotational movement of the link bar (300) by opening the link receiving space (110).

[0084] In addition, when the subframe (220) rotates and moves relative to the mainframe (210), the link receiving space (110) can be closed through the rotation of the link cover (121) due to the pressure of the subframe (220), so that the phenomenon of a part of the user's body or an object being caught or inserted into the link receiving space (110) can be prevented.

[0085] In addition, when the subframe (220) rotates and moves relative to the mainframe (210), the sliding shutter (132) slides in conjunction with the link bar (300), so that when viewed from above, the exposure of a gap in which a part of the user's body or an object can be caught or inserted into the link receiving space can be prevented.

[0086] In addition, when the user wants to take a rest or use the massage module, the subframe (220) can be moved relatively from a first state where it overlaps the upper side of the mainframe (210) to a second state where the subframe (220) is positioned more forward than the first state, thereby converting the mainframe (210) and the subframe (220) into a flat state.

[0087] In addition, when the subframe (220) rotates and moves relative to the mainframe (210), the subframe (220) can be placed in a first state in which it overlaps the upper side of the mainframe (210), and a second state in which the subframe (220) is positioned further forward than the first state, so that the subframe (220) can overlap or unfold with respect to the mainframe (210).

[0088] In addition, since the sub-link (320) is rotatably connected between the main frame (210) and the sub-frame (220) together with the main link (310), when the sub-frame (220) moves relative to the main frame (210), the sub-link (320) and the main link (310) can stably induce the relative movement of the sub-frame (220) with respect to the main frame (210).

[0089] In addition, the main link (310) and the sub link (320) are formed to form a predetermined angle smaller than a flat angle, thereby connecting the main frame (210) and the sub frame (220), thereby preventing the main link (310) or the sub link (320) from being exposed to the outside of the bed (1) when the bed (1) is viewed from the side in a second state in which the sub frame (220) is positioned more forward than in the first state.

[0090] Although the embodiments of the present invention have been described as specific embodiments, these are merely examples, and the present invention is not limited thereto, but should be construed to have the broadest scope in accordance with the technical concepts disclosed in this specification. Those skilled in the art may combine / substitute the disclosed embodiments to implement patterns of shapes not specified, but this also does not depart from the scope of the present invention. In addition, those skilled in the art may easily modify or alter the disclosed embodiments based on this specification, and it is clear that such modifications or alterations also fall within the scope of the present invention.
