Description

[Technical field]

[0001] The present invention relates to a foldable cot. [Background technology]

[0002] When lying down on the ground during outdoor camping trips, even with a sleeping bag or sheet, it may be difficult to get a comfortable sleep due to factors such as the hardness of the ground, the cold air and humidity coming from the ground, etc.

[0003] In contrast, a camping simple sleeping platform, commonly known as a cot, separates the user from the ground, protecting them from the hardness of the ground and the cold and humidity that can come from the ground, and provides a comfortable place to sleep.

[0004] Considering use as camping equipment, it is preferable that the cot can be easily assembled and disassembled, and can be stored compactly.

[0005] For example, Patent Document 1 proposes a cot that is easy to store because the parts do not fall apart when disassembled, and is convenient to carry because its volume becomes significantly smaller after storage. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3229622 Summary of the Invention [Problem to be solved by the invention]

[0007] However, when storing the cot described in Patent Document 1, the leg pipe assembly is rotated and folded in a direction in which the pair of bed support pipes move away from each other, which requires the adjustment part (such as a zipper) to be operated each time in order to fold it without removing the fabric main body, making the storage operation cumbersome.

[0008] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a folding bed that is easy to use and can be assembled and stored more simply. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention provides: A foldable bed surface, a pair of support beams provided on two opposing sides of the bed surface, and a plurality of support legs each supporting both of the pair of support beams, The bed surface, the pair of support beams, and the plurality of support legs are integrally formed, Each of the pair of support beams has a plurality of beam bodies and a plurality of beam joints that connect the plurality of beam bodies to configure the pair of support beams to be foldable, Each of the plurality of support legs has a plurality of leg bodies and a leg joint that configures the plurality of support legs to be foldable by connecting the plurality of leg bodies, Each of the multiple support legs is configured to be foldable around the leg joint as an axis in a direction in which the pair of support beams approach each other.

[0010] The present invention having the above-mentioned configuration is easy to store and keep, since each part is integrally constructed. In addition, since the support legs can be folded in the direction in which the pair of support beams approach each other, the assembly and storage operations can be performed more easily without removing the bed surface and without adding any other structure to the bed surface. Furthermore, since there is no need to add any other configuration to the bed surface, the comfort of the user lying on the bed surface is improved.

[0011] In a preferred embodiment of the present invention, the leg body and the leg joints form a stopper mechanism capable of controlling whether or not the plurality of support legs can be folded.

[0012] According to the above configuration, the multiple support legs are prevented from being folded at a time unintended by the user, and stability during use is improved.

[0013] In a preferred embodiment of the present invention, the leg joint includes a leg covering portion that limits the folding direction of the plurality of support legs to a direction in which the pair of support beams approach each other.

[0014] According to the above configuration, the multiple support legs are prevented from folding in unintended directions, improving stability during use and convenience during assembly and storage.

[0015] In a preferred embodiment of the present invention, each of the plurality of support legs is connected to the pair of support beams via each of the plurality of beam joints.

[0016] According to the above configuration, during assembly, the support beam and support leg are unfolded starting from the beam joint, and during storage, the support beam and support leg are folded so that the beam body and leg body are gathered at the beam joint, making assembly and storage even easier.

[0017] In a preferred form of the present invention, the multiple beam joints include a beam covering portion extending toward the end of the support beam 2, and the length of the beam covering portion is equal to the sum of the widths of the beam main body and the leg main body located toward the end of the support beam relative to the beam covering portion.

[0018] According to the above configuration, when stored, the beam body and the leg bodies folded so as to come together at the beam joint are less likely to interfere with each other, making storage easy and compact.

[0019] In a preferred embodiment of the present invention, each of the plurality of support legs has a ground contact portion and a non-ground contact portion, the ground contact portion and the non-ground contact portion form an arch shape, and the leg joint is provided in the non-ground contact portion.

[0020] According to the above configuration, the arch shape ensures the strength of the support leg, and since the leg joint is located in a non-grounded area, the risk of failure of the leg joint due to clogging with pebbles, sand, etc. is reduced. Effect of the Invention

[0021] According to the present invention, the support legs can be folded in the direction in which the pair of support beams approach each other, so that assembly and storage operations can be performed more easily without removing the bed surface and without adding any other structure to the bed surface.

[0023] Hereinafter, a folding bedding according to an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the embodiment shown below is an example of the present invention, and the present invention is not limited to the following embodiment. In the following description, the symbol X denotes a folding bed according to an embodiment of the present invention.

[0024] As shown in FIG. 1, the folding bed X includes a bed surface 1, a pair of support beams 2, and a plurality of support legs 3.

[0025] Typically, the bed surface 1 is made of a cloth-like material so that it can be folded when stored. In addition, the bed surface 1 may be made of a member such as an air mattress that can be folded by discharging the injected air. Furthermore, if the bed surface 1 is made of a water-repellent material, it is even more suitable for use outdoors.

[0026] The support beams 2 are provided in pairs on two opposing long sides of the bed surface 1. The support legs 3 are shaped like an inverted arch, and each supports both of the pair of support beams 2.

[0027] The bed surface 1, the pair of support beams 2, and the multiple support legs 3 are integrally formed. The folding bed X is configured so that each part does not separate even during the storage process, that is, each part can be stored without being separated.

[0028] As shown in FIG. 2, each of the pair of support beams 2 has a plurality of beam bodies 21 and a plurality of beam joints 22.

[0029] The multiple beam bodies 21 are connected via beam joints 22 . The beam joints 22 connect each of the multiple beam bodies 21 so that each of the multiple beam bodies 21 can be bent inward (toward the side where the bed surface 1 is located). That is, each of the pair of support beams 2 is configured to be foldable by bending the beam body 21 around the beam joint 22 as an axis.

[0030] As shown in FIG. 3, each of the plurality of support legs 3 has a plurality of leg bodies 31 and leg joints 32. In addition, the multiple leg bodies 31 and leg joints 32 are connected together to form a large inverted arch shape including the ground contact portion 33 and the non-ground contact portion 34, while the ground contact portion 33 and the non-ground contact portion 34 form a small arch shape.

[0031] In addition, the multiple leg bodies 31 are connected to the beam body 21 forming the pair of support beams 2 via beam joints 22. That is, the multiple support legs 3 formed of the multiple leg bodies 31 and the leg joints 32 are connected to the pair of support beams 2 via the beam joints 22.

[0032] The leg joints 32 rotatably connect the multiple leg bodies 31 together, thereby making the multiple support legs 3 formed by the multiple leg bodies 31 and the leg joints 32 foldable.

[0033] As shown in Figure 3, the leg joints 32 rotatably connect the multiple leg bodies 31 in a direction in which the beam bodies 21 that form a pair of support beams 2 approach each other, and the multiple support legs 3 formed by the multiple leg bodies 31 and the leg joints 32 are configured to be foldable in that direction.

[0034] Fig. 4 is a diagram showing the periphery of leg joint 32 from above in support leg 3 shown in Fig. 3. The areas indicated by dotted lines in Fig. 4 are transparent parts. As shown in FIG. 4, the leg joint 32 includes a leg covering portion 32a and a pin P.

[0035] The leg covering portion 32a covers the leg main body 31 fixed to the leg covering portion 32a by a pin P in a manner that leaves one direction perpendicular to the pin P open. As a result, the leg covering portion 32a restricts the rotation direction of the leg body 31 fixed by the pin P to a direction in which the beam bodies 21 forming the pair of support beams 2 approach each other. In addition, the leg covering portion 32a covers the entire circumference of the other leg body 31 fixed to the leg covering portion 32a, preventing the leg body 31 from rotating, thereby improving stability during use.

[0036] Fig. 5 is a schematic perspective view of the leg covering part 32a of the leg joint 32. The areas indicated by dotted lines in Fig. 5 indicate see-through parts. 4, the leg body 31 includes a button B and a leaf spring L, and as shown in Fig. 5, the leg covering portion 32a includes a through hole H. The button B, the leaf spring L, and the through hole H constitute a stopper mechanism S.

[0037] The stopper mechanism S controls whether the leg main body 31 fixed to the leg covering portion 32a by the pin P can rotate. In other words, the stopper mechanism S controls whether the multiple support legs 3 formed of the multiple leg main bodies 31 fixed to the leg covering portion 32a by the pins P can be folded.

[0038] Specifically, the user can release the engagement between the through hole H and the button B by pushing in the button B, which is engaged in the through hole H, using the elastic force of the leaf spring L, thereby making the leg body 31, which is fixed to the leg covering portion 32a by the pin P, rotatable.

[0039] Further, the leg covering part 32a is provided with a guide groove G provided above the through hole H (on the bed surface 1 side) and the width of which gradually decreases from the top (on the bed surface 1 side) to the bottom (on the ground side). When the support leg 3 is unfolded, the guide groove G naturally pushes in the button B of the leg body 31 approaching the opening direction of the leg covering portion 32a, and guides the through hole H into the button B, thereby making the unfolding operation of the support leg 3, i.e., the assembly operation of the folding bed X, even easier.

[0040] On the other hand, since the width of the guide groove G gradually decreases from top to bottom, it assists in pressing the button B when the button B moves from top to bottom (e.g., during an unfolding operation), but does not assist in pressing the button B when the button B moves from bottom to top (e.g., during a storage operation). That is, the stability of the multiple support legs 3 during use is improved.

[0041] Hereinafter, the stowing operation of the folding bed X according to the embodiment of the present invention will be described with reference to the attached drawings.

[0042] First, as shown in FIG. 6(a), the user folds the support legs 3 in order from the unfolded state of the foldable bed X (FIG. 1) to bring the pair of support beams 2 closer to each other. Although the bed surface 1 is not shown in Figure 6(a), during the above-mentioned storage operation, the distance between the pair of support beams 2 does not exceed the width of the bed surface 1, and there is no need to remove the bed surface 1 or perform operations such as adjusting the width. FIG. 6(b) shows the actual folding bed X including the bed surface 1 in the state during the above-mentioned storage operation.

[0043] Next, as shown in FIG. 7, the user folds the support leg 3 and the beam body 21 inwardly starting from the end of the support beam 2, with the pin P provided at the beam joint 22 acting as the pivot axis.

[0044] As shown in Figure 8, the length of the beam covering portion 22a extending toward the end of the support beam 2 is equal to the sum of the widths of the beam body 21 and the leg body 31 (or the support leg 3 including the leg body 31 and the leg joint 32) located toward the end of the support beam 2 than the beam covering portion 22a. In addition, the area indicated by the dotted line in FIG. 8 indicates the beam body 21, the leg main body 31, and the supporting leg 3 including the leg joint 32 in the folded state.

[0045] Specifically, the length L1 of the beam covering portion 22a(1) is equal to the sum of the widths of the beam main body 21 and the leg main body 31 located on the end side of the support beam 2 from the length L1. Further, the length L2 of the beam covering portion 22a(2) is equal to the sum of the widths of the two beam main bodies 21 and the two leg main bodies 31 located on the end side of the support beam 2 from the length L2.

[0046] By doing this, when performing the storage operation shown in Figure 7, the beam body 21 and the leg body 31 folded together at the beam joint 22 are less likely to interfere with each other, making storage easy and compact.

[0047] FIG. 9 shows the folding bed X according to the embodiment of the present invention folded by the storage operation shown in FIGS. 9(a) shows the folding bed X without the bed surface 1, and FIG. 9(b) shows the actual folding bed X including the bed surface 1 after the above-mentioned storage operation.

[0048] After folding the folding bed X into the form shown in FIG. 9, the user can store the folding bed X in a dedicated storage bag or the like and transport the folding bed X to any desired location.

[0049] According to this embodiment, each of the multiple support legs 3 is configured to be foldable around the leg joint 32 as an axis in a direction in which the pair of support beams 2 approach each other, making it easier to assemble and store the bed without removing the bed surface 1. Furthermore, since there is no need to add any other configuration to the bed surface 1, the comfort of the user lying on the bed surface 1 is improved.

[0050] In addition, the leg body 31 and the leg joints 32 form a stopper mechanism S that can control whether the multiple support legs 3 can be folded, thereby preventing the multiple support legs 3 from being folded at a time not intended by the user, thereby improving stability during use.

[0051] In addition, the leg joint 32 includes a leg covering portion 32a that limits the folding direction of the multiple support legs 3 to a direction in which the pair of support beams 2 approach each other, thereby preventing the multiple support legs 3 from folding in an unintended direction, improving stability during use and convenience when assembling and storing.

[0052] In addition, since each of the multiple support legs 3 is connected to a pair of support beams 2 via each of the multiple beam joints 22, the support beam 2 and the support legs 3 are unfolded starting from the beam joints 22 during assembly, and the support beam 2 and the support legs 3 are folded so that the beam body 21 and the leg body 31 are gathered at the beam joints 22 during storage, making assembly and storage even easier.

[0053] In addition, the multiple beam joints 22 include a beam covering portion 22a extending toward the end portion of the support beam 2, and the length of the beam covering portion 22a is equal to the sum of the widths of the beam main body 21 and the leg body 31 that are located closer to the end portion of the support beam 2 than the beam covering portion 22a.Therefore, when stored, the folded beam main body 21 and leg body 31 are less likely to interfere with each other, and storage can be made easy and compact.

[0054] In addition, each of the multiple support legs 3 has a grounding portion 33 and a non-grounding portion 34, the grounding portion 33 and the non-grounding portion 34 forming an arch shape, and the leg joint 32 is provided in the non-grounding portion 34. Therefore, the arch shape ensures the strength of the support legs 3, and since the leg joint 32 is provided in the non-grounding portion 34, the risk of failure of the leg joint 32 is reduced.

[0055] The configurations and functions shown in the above embodiments are merely examples, and various modifications are possible based on design requirements, etc. [Explanation of symbols]
