Description

Technical Field

[0001] This application generally relates to inflatable beds. More specifically, this application relates to an inflatable bed configured to limit the expansion or deformation of the inflatable bed during use. Background Art

[0002] Inflatable beds are well known in the art and have proven to be very useful. On the one hand, when the inflatable bed is not needed, the user can simply deflate the inflatable bed (i.e., release all the air), fold it up, and then store it in a storage box. On the other hand, when guests arrive or the user of the inflatable bed travels to a place where there is no bed to sleep, the user can simply inflate the inflatable bed and sleep on it.

[0003] Current inflatable mattresses typically use polyvinyl chloride (PVC) to manufacture the top plate, bottom plate, side plates, and the connecting parts between the top plate and the bottom plate. However, current inflatable beds are relatively heavy, not easy to carry, and at the same time, the cost is relatively high. Summary of the Utility Model

[0004] The purpose of this application is to provide an improved inflatable bed that overcomes some defects in the prior art.

[0005] The inflatable bed according to an embodiment of this application includes a top plate, a bottom plate, and a drawstring connecting the top plate and the bottom plate. First connection parts are provided at the upper and lower ends of the drawstring, and second connection parts are provided at the left and right ends of the drawstring. The drawstring is a fabric drawstring; the first connection parts fix the drawstring between the top plate and the bottom plate, and the upper and lower ends of the second connection parts are fixed to the top plate and the bottom plate.

[0006] The inflatable bed of this application is relatively light, easy to carry, and at the same time, the cost is relatively low. Description of the Drawings

[0010] In the following description, different embodiments of the present application will be described. For the purpose of explanation, specific structures and details are presented to provide a thorough understanding of the embodiments. However, the present application can be implemented without specific details for those skilled in the art. In addition, well-known features will be omitted or simplified to make the described embodiments clear.

[0011] First Embodiment

[0012] Reference Figure 1 , the inflatable bed 10 of the first embodiment of the present application includes a top plate 12, a bottom plate 14, and side plates (not shown in the figure). Generally, the top edge of the side plates is connected to the edge of the top plate 12, and the bottom edge of the side plates is connected to the edge of the bottom plate 14, so that an air chamber is formed when the inflatable bed 10 is inflated.

[0013] A drawstring 16 is provided between the top plate 12 and the bottom plate 14. First connection portions 18 are provided at the upper and lower ends of the drawstring 16 (the connection portion at the upper end is not shown). At least one through hole is distributed on the drawstring 16, aiming to reduce the weight of the drawstring structure. Furthermore, the weight of the inflatable bed using this drawstring structure will also be reduced, thereby reducing the burden of carrying. In this embodiment, preferably, the holes 20 on the drawstring 16 penetrate the drawstring 16 along the thickness direction of the drawstring 16, so as to achieve weight reduction. Among them, the drawstring 16 can preferably be a fabric with mesh holes, such as mesh cloth. The mesh holes can be circular, hexagonal, rhombic, etc. Of course, they can also be other regular or irregular hole shapes.

[0014] The first connection portion 18 can be composed of a single hot melt layer, or can be formed by laminating a hot melt layer and a fabric layer. For example, it can be a fabric with a hot melt layer backing, or can be formed by laminating a top layer and a bottom layer of hot melt layer with an intermediate fabric layer. The hot melt layer can be, for example, PVC (polyvinyl chloride), TPU (thermoplastic polyurethane rubber), PU (polyurethane), PEVA (polyethylene-vinyl acetate), etc. The fabric layer can preferably adopt a mesh fabric.

[0015] In one embodiment, the first connection portion 18 is bonded to one side of the edges at the upper and lower ends of the drawstring 16, and the first connection portion 18 penetrates through the holes 20 of the drawstring 16 and is welded to the top plate 12 or the bottom plate 14 on the other side of the drawstring 16, thereby fixing the drawstring 16 inside the inflatable bed 10. In another embodiment, when the first connection portion 18 is formed by laminating a hot melt layer and a fabric layer, the first connection portion 18 can be connected to the drawstring 16 by sewing, and then the first connection portion 18 is welded to the top plate 12 or the bottom plate 14 alone.

[0016] The left and right ends of the drawstring 16 are provided with second connecting portions 22. The second connecting portion 22 can be composed of a single heat-melt layer, or can be composed of a composite of a heat-melt layer and a fabric layer. For details, reference can be made to the first connecting portion 18. Optionally, the second connecting portion 22 is configured to clamp the drawstring on both sides of the drawstring 16 so as to be fixedly connected to the drawstring 16. In one embodiment, the second connecting portion 22 can be a single piece. When connecting, the single-piece second connecting portion 22 is folded in half, and the two folded parts are welded to each other through the holes 20 of the drawstring 16, so as to fixedly connect the second connecting portion 22 to the drawstring 16. In another embodiment, the second connecting portion 22 can be two pieces. When connecting, the two second connecting portions 22 are respectively placed on both sides of the drawstring 16, and the two second connecting portions 22 are welded through the holes 20 of the drawstring 16, so as to fixedly connect the second connecting portion 22 to the drawstring 16. Optionally, when the second connecting portion 22 is composed of a composite of a heat-melt layer and a fabric layer, the second connecting portion 22 and the drawstring 16 can also be connected by sewing.

[0017] The upper and lower ends of the second connecting portion 22 are respectively welded to the top plate 12 and the bottom plate 14, so as to fixedly connect the second connecting portion 22 inside the inflatable bed 10. The outer edge of the second connecting portion 22 relative to the drawstring 16 is configured to be concave toward the drawstring 16, so as to prevent the edge of the second connecting portion 22 from being damaged by force when the inflatable bed 10 is inflated, resulting in air leakage of the top plate 12 or the bottom plate 14.

[0018] Second Embodiment

[0019] Reference Figure 2 , the inflatable bed 30 of the second embodiment of the present application includes a top plate 32, a bottom plate 34 and side plates (not shown in the figure). Usually, the top edge of the side plate is connected to the edge of the top plate 32, and the bottom edge of the side plate is connected to the edge of the bottom plate 34, so that an air chamber is formed when the inflatable bed 30 is inflated.

[0020] A drawstring 36 is arranged between the top plate 32 and the bottom plate 34. At least one through hole is distributed on the drawstring 36, and the purpose is to reduce the weight of the drawstring structure. Furthermore, the weight of the inflatable lathe using the drawstring structure will also be reduced, thereby reducing the burden of carrying. In this embodiment, preferably, the hole 38 on the drawstring 36 penetrates the drawstring 36 along the thickness direction of the drawstring 36, so as to achieve weight reduction. Among them, the drawstring 36 can be preferably a fabric with mesh holes, such as mesh cloth. The mesh holes can be circular, hexagonal, rhombic, etc. Of course, they can also be other regular or irregular hole shapes.

[0021] The upper and lower ends of the drawstring 36 are provided with first connecting portions 40, and the left and right ends are provided with second connecting portions 42. The first connecting portion 40 or the second connecting portion 42 can be composed of a single hot-melt layer, or can be composed of a composite of a hot-melt layer and a fabric layer. For example, it can be a fabric with a hot-melt layer backing, or can be formed by laminating a top and bottom hot-melt layer with an intermediate fabric layer. The hot-melt layer can be, for example, PVC (polyvinyl chloride), TPU (thermoplastic polyurethane rubber), PU (polyurethane), PEVA (polyethylene-vinyl acetate), etc. The fabric layer can be, for example, a mesh fabric.

[0022] Optionally, the first connecting portion 40 and the second connecting portion 42 are configured to clamp the drawstring 36 on both sides of the drawstring 36 so as to be fixedly connected to the drawstring 36. In one implementation, the first connecting portion 40 or the second connecting portion 42 can be a single piece. When connecting, the single-piece first connecting portion 40 or the second connecting portion 42 is folded in half, and the two folded parts are welded to each other through the hole 38 of the drawstring 36, so as to fixedly connect the first connecting portion 40 or the second connecting portion 42 to the drawstring 36. In another implementation, the first connecting portion 40 or the second connecting portion 42 can be two pieces. When connecting, the two first connecting portions 40 or the second connecting portions 42 are respectively placed on both sides of the drawstring 36, and the two first connecting portions 40 or the second connecting portions 42 are welded through the hole 38 of the drawstring 36, so as to fixedly connect the first connecting portion 40 or the second connecting portion 42 to the drawstring 36. The two pieces of the first connecting portion 40 or the second connecting portion 42 can be inconsistent in size and shape. For example, as Figure 2 shown, the width dimension of one of the first connecting portion 40' or the second connecting portion 42' is much smaller than the width dimension of the other first connecting portion 40 or the second connecting portion 42, which can further reduce the weight of the inflatable bed. Optionally, when the first connecting portion 40 or the second connecting portion 42 is composed of a composite of a hot-melt layer and a fabric layer, the first connecting portion 40 or the second connecting portion 42 can also be connected to the drawstring 36 by sewing.

[0023] The first connecting portions 40 at the upper and lower ends are respectively welded to the top plate 32 or the bottom plate 34, and the upper and lower ends of the second connecting portion 42 are respectively welded to the top plate 32 or the bottom plate 34, so as to fixedly connect the first connecting portion 40 and the second connecting portion 42 to the inside of the inflatable bed 30. The second connecting portion 42 is configured to be concave inward toward the drawstring 36 relative to the outer edge of the drawstring 36, so as to prevent the edge of the second connecting portion 42 from being damaged by force when the inflatable bed 30 is inflated, resulting in air leakage of the top plate 32 or the bottom plate 34.
