Description

Technology Field

[0001] The present invention relates to a foldable bed comprising a left frame, a right frame, and two or more support frames connected between them and coupled to the lower side so as to be foldable, and a cover that supports a user while coupled to the left frame and the right frame, wherein the load support of the user is reinforced at the front and rear ends of the cover using a reinforcing band, and tension is applied to maintain the unfolded state of the cover using an extension band extending outward from the corner side of the cover. Background Technology

[0003] As the number of single-person households increases and individual activities become more frequent, folding beds are being widely used for rest or sleeping both indoors and outdoors.

[0004] Foldable beds, which can be stored folded and unfolded for rest or sleep, are gaining popularity as essential household items or leisure products for outdoor activities due to their advantages of not taking up much space and being easy to use as a bed.

[0005] FIG. 6 is a partial perspective view of a foldable bed according to an example of the prior art, and FIG. 7 is a schematic diagram illustrating the usage state of a foldable bed according to an example of the prior art.

[0006] A conventional foldable bed comprises two longitudinal frames (1200), two transverse frames (1300) respectively provided at one end and the other end of the two longitudinal frames (1200), two or more support frames (1400) connected to the lower side so as to be foldable between the longitudinal frames (1200), and a rectangular cover (1100) configured to support a user while connected to the transverse frames (1300) and the longitudinal frames (1200).

[0007] As shown in FIG. 6, the two longitudinal frames (1200) and two transverse frames (1300) may be configured such that a coupling projection (1210) formed on the longitudinal frame (1200) is inserted into a coupling hole (1310) formed on the longitudinal frame (1300) to fix each frame, and the longitudinal frame (1200) and the transverse frame (1300) may be fixed by mutual contact alone due to pulling by the tension of the cover (1100) through which the two longitudinal frames (1200) and the two transverse frames (1300) are inserted.

[0008] The above longitudinal frame (1200) is combined with the above transverse frame (1300) and support frame (1400) respectively to support the user as a whole, and the above transverse frame (1300) is configured to minimize the cover (1100) sinking due to the user's weight at the center, particularly including the user's head side and leg side.

[0009] In one embodiment of the present invention, the folding bed is folded while the transverse frame (1300) is separated.

[0010] As shown in FIG. 7, when the foldable bed is in a folded state, first the folded part of the longitudinal frame (1200) is unfolded (A1), and then the support frame (1400) is unfolded while spreading the two longitudinal frames (1200) apart (A2) (A3), the foldable bed is unfolded, and then the transverse frame (1300) is attached to the cover (1100) to complete the state that the user can use.

[0011] However, the conventional folding bed exemplified above had the inconvenience that, during the process of connecting the transverse frame (1300) to the cover (1100) and finally connecting it to the longitudinal frame (1300), the user had to apply a large amount of force due to the pulling caused by the tension of the cover (1100) to ensure smooth installation. In particular, when initially installing the transverse frame (1300) on one side (e.g., foot side), there is no tension in the cover (1100), but when finishing installing the transverse frame (1300) on the other side (e.g., head side), the tension in the cover (1100) is significant, so there was a problem that the installation process was not easy for women or children with weak strength.

[0031] Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the attached drawings.

[0032] FIG. 1 is a perspective view of a foldable bed according to an embodiment of the present invention, FIG. 2 is a bottom perspective view of a foldable bed according to an embodiment of the present invention, FIG. 3 is a bottom plan view of a cover according to an embodiment of the present invention, FIG. 4 is a schematic diagram for explaining the usage state of a foldable bed according to an embodiment of the present invention, and FIG. 5 is another schematic diagram for explaining the usage state of a foldable bed according to an embodiment of the present invention.

[0033] The foldable bed (10) of the present embodiment is provided with a left frame (201), a right frame (202), and two or more support frames (300) connected between them and connected to the lower side so as to be foldable, and includes a cover (100) that supports a user while connected to the left frame (201) and the right frame (202), wherein the load support of the user is reinforced at the front and rear ends of the cover (100) using a reinforcing band, and tension is applied to maintain the unfolded state of the cover (100) using an extension band extended outward from the corner side of the cover (100).

[0034] The above-mentioned left frame (201) and right frame (202) are spaced apart from each other and arranged along the front-rear direction (FB), and each is provided with a protruding connecting pin (P) at the front end and rear end.

[0035] The above left frame (201) and right frame (202) may be configured to be separated into front and rear ends, respectively, so that the foldable bed (10) according to the present embodiment can be folded around the center of the front-rear direction (FB), and may be combined by means of a bracket (not shown) and a hinge (not shown), etc., to enable folding.

[0036] The support frame (300) is connected between the left frame (201) and the right frame (202) and is connected to the lower side so as to be foldable, and two or more are installed with a gap in the front-rear direction (FB). In the case of this embodiment, a total of three support frames (300) are installed, and each support frame (300) is configured such that two frame beams are connected so as to be foldable in a scissor shape around a central hinge. One of the two frame beams is connected to the left frame (201), and the other is connected to the right frame (202).

[0037] The above cover (100) is configured to support the user while connected to the left frame (201) and the right frame (202).

[0038] In a preferred example, the cover (100) has a cover body (101) having a rectangular flat shape in the unfolded state.

[0039] Additionally, the cover (100) is provided with left and right edge portions (S1, S2) formed along the front-rear direction (FB) on the left and right edge sides and into which the left frame (201) or the right frame (202) is inserted, and left and right exposed portions (N1, N2) formed respectively in the middle of the left and right edge portions (S1, S2) so that the left connecting portion between the left frame (201) and the support frame (300) and the right connecting portion between the right frame (202) and the support frame (300) are exposed respectively.

[0040] In a preferred example, the cover (100) is provided with a front reinforcing band (111) and a rear reinforcing band (112) that are integrally attached across the left-right direction (LR) at the front position (FE) and rear position (BE) of the cover body (101). In an example, the front reinforcing band (111) and the rear reinforcing band (112) may be attached to the bottom side of the cover (100).

[0041] For example, the front reinforcing band (111) and the rear reinforcing band (112) are attached integrally to the cover (100) through sewing.

[0042] The above front reinforcing band (111) and rear reinforcing band (112) function to minimize the sinking of the cover (100) by the user's load from the center side, including the user's head side and leg side, by replacing the transverse frame of the existing folding bed.

[0043] The foldable bed (10) of this embodiment does not include the lateral frame of a conventional foldable bed, so there is no need to insert or remove the lateral frame during installation and removal.

[0044] To this end, preferably, the front reinforcing band (111) and the rear reinforcing band (112) are made of a material with less elasticity than the cover body (101).

[0045] The term 'material' as used in the present invention may refer to a raw material used to make something, or an intermediate processed material made from the raw material.

[0046] For example, the fact that the second material has 'less elasticity' than the first material may mean that a raw material with less elasticity was used for the second material, or that the same raw material was processed to have less elasticity.

[0047] For example, the cover and reinforcing band of the present embodiment may be made of synthetic fiber materials such as polyester or polypropylene. For example, processing the fiber material to have less elasticity can be achieved by making the weaving structure more rigid or by increasing the weaving density.

[0048] In a preferred example, the cover (100) is attached based on the front reinforcing band (111) or the rear reinforcing band (112) and has first to fourth extension bands (121 to 124) that extend outward from each corner side of the cover body (101) and each have a coupling hole (H) formed in the extended portion.

[0049] The fact that the first to fourth extension bands (121 to 124) are attached based on the front reinforcing band (111) or the rear reinforcing band (112) can be understood to mean that the first to fourth extension bands (121 to 124) have a portion that overlaps and is sewn with the front reinforcing band (111) or the rear reinforcing band (112). In this sewn state, the tension applied to the first to fourth extension bands (121 to 124) is transmitted to the cover (100) through the reinforcing function of the front reinforcing band (111) or the rear reinforcing band (112), so a robust usage state can be provided compared to the case where the first to fourth extension bands (121 to 124) directly transmit tension to the cover (100) without being reinforced by the front reinforcing band (111) or the rear reinforcing band (112).

[0050] Preferably, the first to fourth extension bands (121 to 124) are made of a material with less elasticity than the cover body (101).

[0051] Through the above configuration, the cover (100) is configured such that a protruding coupling pin (P) at a corresponding position among the protruding coupling pins provided at the front or rear end of the left frame (201) or the right frame (202) is inserted and coupled into each coupling hole (H) formed in the first to fourth extension bands (121 to 124), thereby providing tension to maintain the unfolded state of the cover (100). Through this, the cover (100) can minimize sagging even when a user's load is applied.

[0052] In order to provide tension for maintaining the unfolded state of the cover (100) in a state where the protruding coupling pin (P) at a position corresponding to each coupling hole (H) is inserted and coupled, the spacing between the coupling holes (H) in the unfolded state of the cover (100) is configured to be equal to or slightly smaller than the spacing between the protruding coupling pins (P) in the unfolded state of the left frame (201) and the right frame (202). Since the cover (100) is typically made of a fiber material or a synthetic resin sheet material having some elasticity, when the user unfolds and installs the foldable bed (10), the user can apply tension by pulling the first to fourth extension bands (121~124) with their hand to tension the cover (100) and / or the first to fourth extension bands (121~124), insert and coupled the protruding coupling pin (P) at a position corresponding to each coupling hole (H), and release the tension.

[0053] Additionally, the first to fourth extension bands (121 to 124) are configured such that, when a protruding coupling pin (P) at a corresponding position among the protruding coupling pins (P) provided at the front or rear end of the left frame (201) or the right frame (202) is inserted and coupled into each coupling hole (H), the band-side Velcro (V1) provided at each end of the first to fourth extension bands (121 to 124) is attached and coupled to the main body-side Velcro (V2) provided at each corner of the cover main body (101). This Velcro coupling allows for more robust tension to be applied to maintain the unfolded state of the cover (100) and keeps the ends of the first to fourth extension bands (121 to 124) attached in an aesthetically pleasing manner in the installed state.

[0054] For example, the cover (100) is provided with a first reinforcing band (131) that is integrally attached across the left-right direction (LR) of the cover body (101) at a position spaced rearward from the front reinforcing band (111).

[0055] The first extension band (121) extends outward from the corner side of the cover body (101) by passing through the left position of the shear reinforcement band (111) from the center side of the first reinforcement band (131), and the second extension band (122) extends outward from the corner side of the cover body (101) by passing through the right position of the shear reinforcement band (111) from the center side of the first reinforcement band (131).

[0056] For example, a second reinforcing band (132) is provided that is integrally attached across the left-right direction (LR) of the cover body (101) at a position spaced forward from the rear reinforcing band (112).

[0057] The third extension band (123) is configured to extend outward from the corner side of the cover body (101) by passing through the left position of the rear reinforcement band (112) from the center side of the second reinforcement band (132), and the fourth extension band (124) is configured to extend outward from the corner side of the cover body (101) by passing through the right position of the rear reinforcement band (112) from the center side of the second reinforcement band (132).

[0058] In a preferred example, the first and second extension bands (121-122) are attached based on the first reinforcing band (131), and the third and fourth extension bands (123-124) are attached based on the second reinforcing band (132).

[0059] Through the above configuration, in order to maintain the unfolded state of the cover (100) in the unfolded state, the front reinforcing band (111) and the rear reinforcing band (112) provide tension in the left-right direction (LR) at the front position (FE) and rear position (BE) of the cover body (101), and the first to fourth extension bands (121 to 124) provide tension directed toward the outer direction (A) at each corner position of the cover body (101). Here, the 'outer direction (A) at the corner position' can be seen as a direction extending approximately radially from the center point of the cover body (101) having a rectangular planar shape.

[0060] Preferably, additional reinforcing bands (141, 142) may be further attached to the middle side of the cover (100).

[0062] The installation process of a foldable bed (10) according to one embodiment of the present invention is described.

[0063] As shown in FIG. 4, when the foldable bed (10) is in a folded state, the folded parts of the left frame (201) and the right frame (202) are first unfolded (A1), and then the support frame (300) is unfolded (A3) while spreading the left frame (201) and the right frame (202) apart.

[0064] Afterwards, a protruding coupling pin (P) at a corresponding position among the protruding coupling pins provided at the front or rear end of the left frame (201) or the right frame (202) is inserted and coupled into each coupling hole (H) formed in the first to fourth extension bands (121 to 124), thereby applying tension to maintain the unfolded state of the cover (100).

[0065] Afterwards, the installation is completed by attaching the band-side Velcro (V1), provided at each end of the first to fourth extension bands (121 to 124), to the main body-side Velcro (V2), provided at each corner of the cover main body (101).

[0066] The removal of the folding bed (10) can be done by reversing the installation process described above.

[0068] Although the present invention has been described with reference to preferred embodiments with reference to the attached drawings, it is evident to those skilled in the art that many diverse and obvious variations are possible from this description without departing from the scope of the present invention. Accordingly, the scope of the present invention should be interpreted by the claims described to include such many variations. Explanation of the symbols
