[0002] Specifically, the invention relates to a retractable bed that can be reduced and expanded in width through a drawer-type operating configuration, thereby enabling it to be provided economically through structural simplification and improving ease of operation. Background Technology

[0003] Generally, due to the modernization of lifestyles and the shift toward communal housing, most households use bedding such as beds and sofas.

[0004] The bed mentioned above is a type of bedding designed to provide cushioning to the user on its upper surface, allowing them to lie down and sleep comfortably.

[0005] The sofa mentioned above is a type of bedding designed to provide cushioning when configuring the seat, allowing the user to sit comfortably and rest.

[0006] Such beds or sofas are furniture used for a user to sit or lie down comfortably for rest and sleep, and consist of a main body that forms a certain height from the floor and provides space, and a mattress installed on the main body to provide cushioning to the user.

[0007] The mattress described above is formed by creating a sheet with a shock-absorbing material inside, such as coil springs, sponge, or other elastic materials, and covering the outer surface with a cover made of natural or artificial leather and fiber materials.

[0008] Recently, with the spread of bed culture, various sofas and beds designed to be used as a combined unit are being proposed to address issues such as limited space utilization resulting from the use of beds in small spaces, as well as the inability to install and use other furniture like sofas. These products aim to double the efficiency and cost-effectiveness of use along with space utilization.

[0009] One example is Korean Utility Model Application No. 20-2007-0005179 (Title: Bed with sofa function / March 29, 2007), which describes a conventional bed comprising a flat base and a mattress installed on top of the base, wherein the base and the mattress form a divided body by dividing a portion along the longitudinal direction, and the divided body is equipped with an angle adjustment mechanism on both sides to selectively support the rotating divided body at various angles while adjusting the upward rotation of the divided body.

[0010] In addition, Korean Patent Application No. 10-2015-0140895 (Title: Bed for sofa use / October 7, 2015), as disclosed in the publication, comprises: legs supported on the ground and having a bent portion formed therein; a seat plate to which the legs are connected on both sides; a backrest positioned vertically on one long side of the seat plate and unfolded horizontally while rotating; a hinge connecting the seat plate and the backrest rotatably; and a fixing means to maintain the backrest horizontally when it is unfolded horizontally. The seat plate is composed of a cushion formed between the two side frames, with an insertion groove formed therein into which the bent portion of the leg is inserted. The side frames are formed with an arc-shaped end protruding on one side and an insertion groove formed on the other side, and a slit formed inside the insertion groove.

[0011] Meanwhile, Korean Patent Application No. 10-2001-0011296 (Title: Sofa and Bed / March 5, 2001) describes a sofa configured such that, as disclosed in the publication, the two middle panels, back panel, front panel, top panel, and back panel are assembled by bolts and screws via hinges, and there are two armrests on the cushion back panel and two cushion seat cushions, and a bed is installed inside the sofa with cushions inside, and when pulled and unfolded, it becomes a bed.

[0012] In addition, Korean Utility Model Application No. 20-1997-0008231 (Title: Double Bed for Sofa Use / Apr. 19, 1997) describes a bed comprising, as disclosed in the publication, armrest members installed upright on both sides of a main body frame while maintaining a certain width; a horizontal cushion member having a cushion spring built between the armrest members and a means for forward and backward sliding; a backrest member at the rear end of the horizontal cushion member that is foldable when the horizontal cushion member slides forward and backward; and an auxiliary cushion member on the rear side of the backrest member that slides forward and backward on a guide support bar depending on whether a locking member is fixed or released.

[0014] However, conventional sofa beds such as the above had structurally complex and structurally weak problems that would be damaged if the load was concentrated on the folding hinge area.

[0015] In addition, there was a problem with reduced workability as the user had to exert a lot of force during the folding process.

[0016] The present invention is proposed to solve the aforementioned conventional problems, and the objective of the present invention is to provide a retractable bed that can be economically provided through structural simplification and improved convenience of operation, by allowing the width to be reduced to form a small single bed or sofa or expanded to form a large double bed depending on the user's choice. means of solving the problem

[0017] A retractable bed according to the present invention for achieving the above-described objective comprises: a bed body having a support member positioned at a height relative to the floor and main body supports supporting the support member relative to the floor; a movable body having movable supports connected to the bed body so as to be linearly movable in the width direction, with one end spanning the bed body and the other end supporting the floor; and a foldable mattress having a width that fits the upper part of the bed body when folded, and a width that fits the upper part of the bed body and the unfolded movable body when unfolded; wherein a plurality of guide portions having a length in the width direction and spaced apart from each other are formed on the upper surface of the support member; and wherein the movable body is provided with guide support links having a length in the width direction and spaced apart from each other, which are fitted into and connected to the respective guide portions to be guided.

[0018] The lower part of the support member in the above-mentioned bed body is characterized by being provided with storage containers that guide storage drawers to move in the width direction. Effects of the invention

[0019] The expandable bed according to the present invention, formed in this manner, has the effect of improving space utilization efficiency and usability by allowing the user to choose to fold the movable body relative to the bed body to reduce its overall width and stack the folded mattress on top of the bed body in a folded state to form a small single bed or sofa, or to move the movable body relative to the bed body in the width direction to expand its overall width and form a large two-person bed.

[0020] At this time, by implementing a 'drawer-type operating configuration' in which the guide support links of the movable body are inserted into the guide parts provided on the bed body to enable linear movement and guidance, the overall width is reduced and expanded, thereby enabling economical provision through structural simplification as well as having the effect of improving convenience of operation.

[0021] In addition, fixtures are stored through individual storage drawers that are custom-fitted, accommodated, and combined with the storage containers provided in the bed frame, thereby maximizing usability. Brief explanation of the drawing

[0023] Hereinafter, a retractable bed according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0024] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that in each drawing, identical components may be depicted with the same reference numeral. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0026] FIGS. 1 to 8 are drawings showing a retractable bed (1) according to an embodiment of the present invention. The retractable bed (1) according to the present embodiment comprises: a bed body (2) having a support member (21) positioned at a height relative to the floor and main body supports (22) supporting the support member (21) relative to the floor; a movable body (3) having movable supports (31) that are connected to the bed body (2) so as to be linearly movable in the width direction, with one end spanning the bed body (2) and the other end supporting the floor; and a foldable mattress (4) having a width that fits the upper part of the bed body (2) when folded, and a width that fits the upper part of the bed body (2) and the unfolded movable body (3) when unfolded.

[0027] That is, depending on the user's choice, the movable body (3) is folded over the bed body (2) to reduce its overall width, and the foldable mattress (4) is stacked on top of the bed body (2) in a folded state to form a 'small single bed' or 'sofa'.

[0028] In addition, depending on the user's choice, the movable body (3) is moved to unfold in the width direction relative to the bed body (2) to expand its overall width and form a 'large bed for two people,' thereby improving space utilization efficiency and usability.

[0030] When the movable body (3) is extended as described above, one end is positioned over the bed body (2), so that the width of movement in the width direction relative to the bed body (2) is formed to be smaller than the width of the bed body (2).

[0031] At this time, when the above-mentioned folding mattress (4) is unfolded, it forms a width that matches the total width of the unfolded state of the bed body (2) and the movable body (3).

[0032] To this end, the foldable mattress (4) may include: a main body mattress (41) having a width that fits the upper part of the bed body (2); an extension mattress (42) having a width that fits the movement width of the movable body (3) and is connected to the front end of the main body mattress (41) so as to be foldable and rotatable; and a protruding mattress (43) formed protrudingly in the unlayered area when the extension mattress (42) is folded from the main body mattress (41) and stacked upward.

[0033] That is, regarding the upper part of the main body mat (41), the unlaid portion resulting from the folding of the extension mat (42) is corrected through the protruding mat (43) to form a flat surface on which the user rests, thereby enabling stability in use.

[0035] In the expandable bed (1) according to this embodiment, a plurality of guide portions (23) are formed on the upper surface of the support member (21), having a length in the width direction and spaced apart from each other; and the movable body (3) is provided with guide support links (32) that have a length in the width direction and spaced apart from each other, fitted into and connected to the guide portions (23) to guide each other.

[0036] That is, when the movable body (3) moves in a linear motion in the width direction relative to the bed body (2) to extend and retract its entire width, the guide support links (32) of the movable body (3) are guided in a state where they are fitted into the guide portions (23), so that linear motion is performed in a normal position, thereby increasing operational stability.

[0037] In addition, the overall width is reduced and expanded by implementing a 'drawer-type operating configuration' in which the guide portions (23) of the bed body (2) and the guide support links (32) of the movable body (3) are inserted and guided so as to be capable of linear movement.

[0038] At this time, the above-mentioned folding mattress (4) is supported by being supported through the above-mentioned guide support links (32), thereby ensuring structural stability.

[0039] Accordingly, structural simplification enables not only economical provision but also improved ease of operation.

[0041] In the above, the support member (21) in the bed body (2) may be formed as a 'plate' shaped 'plate' having a width or a 'frame structure' in which a plurality of tubular frames are connected in a 'frame' shape; the guide portions (23) may be formed on the upper surface of the support member (21) with a length in the width direction, or a plurality of guide rails (24) may be combined to form the guide portions (23) through the gaps formed between them while having a length in the width direction on the upper surface of the support member (21).

[0042] In addition, the main body supports (22) may be each connected to the corner portions of the bottom surface of the support member (21) to support the support member (21) against the floor.

[0043] In addition, side plate members (25) configured to block the lower space from the outside are provided at each end of the support member (21) to enhance the decorative aesthetic sense; the side plate members (25) may be made of a 'plate' shaped 'plate material'.

[0045] In the above, the depth of the guide portion (23) is made equal to the height of the guide support link (32), so that when they overlap each other, the upper surface is formed flat, so that no bending occurs when the foldable mattress (4) is stacked, thereby ensuring structural and usage stability.

[0047] The above-described movable body (3) may include a movable frame (34) having a connecting portion (33) formed such that the ends of the guide support links (32) are joined with a gap between them; and movable supports (31) that are joined to the bottom surface of the movable frame (34) and support the movable frame (34) against the floor.

[0048] That is, the above-mentioned movable frame (34) is supported with height relative to the floor through the above-mentioned movable supports (31), and the above-mentioned guide support links (32) are connected and assembled to form the above-mentioned movable body (2).

[0049] At this time, the height of the movable frame (34) relative to the floor is such that the guide support link (32) fits into the guide portion (23) of the bed body (2), thereby ensuring operational stability.

[0051] In the expandable bed (1) according to the present embodiment, the lower part of the support member (21) in the bed body (2) is provided with storage containers (5) that guide storage drawers (51) to move in the width direction.

[0052] That is, each of the storage drawers (51) is fitted and accommodated in the storage containers (5) provided in the bed body (2), and combined so that equipment is stored inside, thereby maximizing the quality of use.

[0054] The configuration and structure of the storage containers (5) and the storage drawers (51) described above may be appropriately applied according to the configuration and structure selected by the user.

[0056] Meanwhile, the expandable bed (1) according to the present embodiment may include an elastic locking means (6) configured to elastically hook and support the movable body (3) to lock it to the bed body (2) so as to maintain a folded state and an unfolded state.

[0057] That is, the movable body (3) can be elastically locked to the bed body (2) through the elastic locking means (6).

[0058] Accordingly, the folded and unfolded states of the above-mentioned movable body (3) are maintained, thereby ensuring stability in use.

[0060] The elastic locking means (6) above may include: a locking rod (62) that is movably fitted into and secured in a guide groove (61) formed in the side wall member (25) at a position close to the side wall member (25); and a locking clip body (64) provided at both inner ends of the guide groove (61) in the side wall member (25), wherein elastic pieces (63) are formed at both ends such that the openings expand and contract elastically while the locking rod (62) enters and exits, and the locking rod (62) is received and secured by connecting the elastic pieces (63).

[0061] That is, the locking rod (62) is inserted into the guide groove (61) and secured, so that when the movable body (3) moves relative to the bed body (2) and its entire width is extended, the locking rod (62) is guided in the guide groove (61), allowing the movement to be performed in a fixed position.

[0062] Accordingly, operational stability can be ensured.

[0063] In addition, when the movable body (3) reaches the position where it forms the maximum and minimum widths with respect to the bed body (2), the locking rod (62) is elastically caught on each of the locking clip bodies (64) and is captured and fixed.

[0064] Accordingly, the above-mentioned movable body (3) is prevented from moving unintentionally, thereby ensuring safety in use.

[0066] The extendable bed (1) according to the present embodiment, as described above, is characterized by a technical configuration in which the guide support links (32) of the movable body (3) are inserted into the guide portions (23) provided on the bed body (2) to allow for linear movement and are guided, thereby reducing and expanding its overall width.
