Description

Technical Field

[0001] The present application relates generally to air mattresses and, more particularly, to an air mattress configured to limit expansion or deformation of the air mattress 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 airbed is no longer needed, the user can simply deflate it (i.e., let out all the air), fold it up, and store it in its storage container. On the other hand, when guests arrive or the airbed user travels to a location where no other bed is available, the user can simply inflate the airbed and sleep on it.

[0003] Current air mattresses are usually made of polyvinyl chloride (PVC) to make a top plate, a bottom plate, side plates and the connecting portion between the top plate and the bottom plate. However, current air mattresses are heavier, are not easy to carry, and are also more expensive. Utility Model Content

[0004] The purpose of this application is to provide an improved inflatable bed, which overcomes some of the shortcomings of the prior art.

[0005] The inflatable bed of an embodiment of the present application includes a top plate, a bottom plate and a plurality of mesh pull straps connecting the top plate and the bottom plate; the mesh pull straps include a plurality of groups of spaced-apart and parallel longitudinal lines extending in the longitudinal direction and a plurality of groups of spaced-apart and parallel transverse lines extending in the transverse direction, the longitudinal lines and the transverse lines intersect with each other to form a plurality of square meshes, and the transverse lines are configured to expand outward in the transverse direction under force.

[0006] As in the inflatable bed of the above embodiment, the expansion rate of the horizontal line that can expand outwards is greater than 5%.

[0007] As in the inflatable bed of the above embodiment, the transverse lines are made of untwisted multifilaments made of non-elastic filaments, and the part of the transverse lines between two adjacent groups of longitudinal lines is loose when there is no force, and when there is force, the part of the transverse lines can be stretched to a compact state.

[0008] As in the inflatable mattress of the above embodiment, the horizontal threads are made of multiple strands of yarn, and the multiple strands of yarn twisted to form the horizontal threads include elastic yarn and non-elastic yarn.

[0009] As in the air mattress of the above embodiment, the elastic yarn serves as the core yarn of the multi-strand yarn.

[0010] As in the air mattress of the above embodiment, the horizontal threads are double-stranded threads, and the two strands of yarn making up the horizontal threads are loosely wound when not under stress, and can be stretched to a compact state when under stress.

[0011] The inflatable bed of the present application is light in weight, easy to carry, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In the following description, different embodiments of the present application will be described. For the purpose of explanation, specific structures and details are proposed in order to provide a thorough understanding of the embodiments. However, for those skilled in the art, the present application can be implemented without the need for specific details. In addition, in order to make the described embodiments clear, known features will be omitted or simplified.

[0022] refer to Figure 1In an exemplary embodiment, the inflatable bed of the present application includes a top plate 11, a bottom plate 12, and side plates (not shown). Typically, the top edges of the side plates are connected to the edges of the top plate 11, and the bottom edges of the side plates are connected to the edges of the bottom plate 12, so that the inflatable bed forms an air chamber when inflated.

[0023] like Figure 1 As mentioned above, the inflatable bed 10 is equipped with a mesh pull strap, an upper fixing plate 31, and a lower fixing plate 32. The mesh pull strap is distributed throughout with multiple square mesh holes, which aims to reduce the weight of the pull strap structure, thereby reducing the weight of the inflatable bed using this pull strap structure, thereby reducing the burden of carrying. The upper fixing plate 31 is attached to the top plate 11 and fixes the upper end 21 of the mesh pull strap in the longitudinal direction between the upper fixing plate 21 and the top plate 11. The lower fixing plate 32 is attached to the bottom plate 12 and fixes the lower end 22 of the mesh pull strap in the longitudinal direction between the lower fixing plate 32 and the bottom plate 12.

[0024] Typically, the sheet materials such as the top plate 11, the bottom plate 12, the side plates, the upper fixing plate 31 and the lower fixing plate 32 can be made of any suitable soft material, such as PVC (polyvinyl chloride), waterproof cloth (laminated with top and bottom PVC films and a nylon mesh in the middle), PE (polyethylene), PEVA (polyethylene-vinyl acetate), EVA (ethylene-vinyl acetate), fabric with PVC backing, fabric with PEVA backing, etc.

[0025] In an embodiment of the present application, the mesh pull belt includes multiple sets of spaced-apart, parallel longitudinal lines extending in the longitudinal direction and multiple sets of spaced-apart, parallel transverse lines extending in the transverse direction, wherein the longitudinal lines and the transverse lines intersect to form a plurality of square meshes. The transverse lines are configured to expand or stretch outward in the transverse direction under load. Specifically, the transverse lines have a first length L1 when not under load and a second length L2 when under load, wherein L2>L1. This is intended to ensure that when the inflatable bed is inflated, the top plate 11 and the bottom plate 12 expand outward in the transverse direction, which in turn causes the longitudinal lines to expand outward in the transverse direction simultaneously. If the transverse lines cannot expand outward, the longitudinal lines will break under the pull of the top plate 11 and the transverse lines, or the bottom plate 12 and the transverse lines, or the longitudinal lines will tear the top plate 11 or the bottom plate 12. The ability of the transverse lines to expand outward under load avoids this situation. In this embodiment of the present application, the transverse expansion ratio of the transverse lines is defined as (L2-L1) / L1, and the transverse expansion ratio is preferably greater than 5%.

[0026] In other embodiments, the longitudinal lines may also be configured to expand or stretch outward in the longitudinal direction under load.

[0027] refer to Figure 2 and Figure 3, the first embodiment of the mesh pull belt (only part of the repeating units of the mesh pull belt are shown in the figure). In this embodiment, the longitudinal threads 41 and transverse threads 42 of the mesh pull belt are both made of untwisted multifilaments made of non-elastic filaments. Multiple groups of spaced and parallel longitudinal threads 41 and multiple groups of spaced and parallel transverse threads 42 intersect with each other to form an array of evenly spaced square meshes 43. Specifically, the mesh pull belt of this embodiment can be woven by weaving or knitting. The portion of the transverse threads 42 between two adjacent groups of longitudinal threads 41 is loose when there is no force (refer to Figure 2 ), which can be stretched to a compact state when subjected to force (refer to Figure 3 ), which allows the transverse lines 42 to expand outwardly in the transverse direction. The longitudinal lines 41 can also be expanded outwardly in the longitudinal direction in a similar manner.

[0028] refer to Figure 4 and Figure 5 , a second embodiment of the mesh pull strap (only some repeating units of the mesh pull strap are shown in the figure). In this embodiment, the longitudinal threads 51 and transverse threads 52 of the mesh pull strap are both made of multi-strand yarns. Multiple groups of spaced-apart and parallel longitudinal threads 51 and multiple groups of spaced-apart and parallel transverse threads 52 intersect with each other to form an array of evenly spaced square meshes 53. Specifically, the mesh pull strap of this embodiment can be woven by weaving or knitting. The multi-strand yarns twisted to form the transverse threads 52 include elastic yarns and inelastic yarns. The elastic yarns usually serve as the yarn core of the multi-strand yarns, which makes the transverse threads 52 elastic and can expand outward in the transverse direction. The elastic yarn can be, for example, spandex yarn. The longitudinal threads 51 can also include elastic yarns and inelastic yarns so that they can expand outward in the longitudinal direction.

[0029] refer to Figure 6-Figure 8 , the third embodiment of the mesh pull belt (only some repeating units of the mesh pull belt are shown in the figure). In this embodiment, the longitudinal threads 61 and transverse threads 62 of the mesh pull belt are both made of double-stranded yarns made of non-elastic filaments. Multiple groups of spaced and parallel longitudinal threads 61 and multiple groups of spaced and parallel transverse threads 62 intersect with each other to form an array of evenly spaced square mesh holes 63. Specifically, the mesh pull belt of this embodiment can be woven by weaving or knitting. The two strands of yarn that make up the transverse threads 62 are loosely wound when not under stress (refer to Figure 7 ), when subjected to force, the two yarns can be stretched to a compact state (refer to Figure 8 ), which allows the transverse line 62 to expand outwardly in the transverse direction. The longitudinal line 61 can also be expanded outwardly in the longitudinal direction in a similar manner.
