Abstract
Description
Technical Field
[0001] The utility model generally relates to an inflatable product, and more particularly to an inflatable mattress for outdoor camping. Background Art
[0002] When camping in the wild, because the ground is cold and hard, and the temperature drops significantly especially at night, campers often need an easy-to-carry inflatable mattress to insulate and provide cushioning.
[0003] Figure 1 The structure of a conventional air mattress 1 is shown. The air mattress 1 includes a top sheet 2 and a bottom sheet 3 connected to each other to form an air chamber. Generally speaking, a human body sleeps on the top sheet 2, and the ground is located below the bottom sheet 3. The air mattress 1 can reduce the heat transfer between the top sheet 2 and the bottom sheet 3 of the air mattress 1, and prevent the contact surface between the human body and the top sheet 2 from being affected by the low temperature of the ground, so as to allow the human body to retain enough heat, thereby enjoying a comfortable sleep and being fully prepared for the activities of the next day.
[0004] The air mattress 1 also includes a plurality of tension members 4, which are arranged in the air chamber at intervals, and the top and bottom ends of each tension member 4 are welded to the top sheet 2 and the bottom sheet 3, respectively, to ensure that the air mattress 1 maintains a predetermined shape in the inflated state. For this type of air mattress 1, during the manufacturing process, it is necessary to manually place the plurality of tension members 4 in appropriate positions relative to the top sheet 2 and the bottom sheet 3, and then weld the plurality of tension members 4 to the top sheet 2 and the bottom sheet 3, respectively, which requires a lot of manual labor and time, resulting in low production efficiency of the air mattress. In addition, when manually positioning and placing the plurality of tension members 4, position errors of the tension members are easily generated, resulting in poor consistency of the air mattress product and unstable yield rate.

After the pressure of the gas (e.g., air) in the inflatable chamber 106 reaches a desired value, the inflatable product 10 is in an inflated state and maintains a preset shape; and when the gas in the inflatable chamber 106 is discharged, the inflatable product 10 is in a deflated state, and the volume of the inflatable product 10 is greatly reduced relative to that when it is in the inflated state, thereby facilitating the storage of the inflatable product 10.
[0050] A sheet-like tensioning member 108 is provided in the inflation chamber 106 of the inflatable product 10. The sheet-like tensioning member 108 is connected to the first wall 102 and the second wall 104 by welding, for example. In this specification, the welding method mentioned includes high-frequency welding, hot pressure welding and any other suitable welding method. After being tensioned, the sheet-like tensioning member 108 provides a pulling force to the first wall 102 and the second wall 104 to limit the deformation of the inflatable product 10, so that the inflatable product 10 can maintain a preset shape after being inflated.
[0051] In the following, taking an inflatable mattress as an example, several non-limiting embodiments of the inflatable product according to the utility model are introduced.
[0052] First embodiment

[0056] The periphery of the first wall 102 and the periphery of the second wall 104 are connected to each other, for example, by welding, to jointly define an inflatable chamber 106. The first wall 102 is used for a user to sit or lie down (the first wall 102 may also be referred to as a top wall or a top sheet), and the second wall 104 is used to contact the ground (the second wall 104 may also be referred to as a bottom wall or a bottom sheet). The first wall 102 and the second wall 104 may have substantially the same shape and size. The first wall 102 and the second wall 104 are substantially parallel. The air valve 110 may be disposed at one end of the inflatable mattress 10 and welded to the first wall 102 as shown in the figure, or may be welded to the second wall 104.

[0057] Optionally, the first wall 102 may include an outer layer away from the inflatable chamber 106 and an inner layer facing the inflatable chamber 106. The inner layer of the first wall 102 contacts the gas in the inflatable chamber, and the outer layer of the first wall 102 faces the outside of the inflatable chamber, that is, contacts the gas outside the inflatable chamber. The outer layer is a fabric layer in contact with the human body, and the inner layer is a polymer material layer. The fabric layer is, for example, made of one or more of cotton fiber, wool fiber, silk fiber, hemp fiber, regenerated fiber, polyester fiber, polyamide fiber, polyacrylonitrile fiber, polyvinyl alcohol fiber, polypropylene fiber, polyurethane fiber and inorganic fiber, and the polymer material layer is, for example, made of one or more of polyvinyl chloride (PVC), thermoplastic polyurethane elastomer (TPU), polyurethane (PU), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), ethylene-vinyl acetate copolymer (EVA), polyamide (PA) and other suitable polymer materials. The second wall 104 may have the same structure as the first wall 102, that is, the second wall 104 may include an outer layer facing away from the air-filled chamber 106 and an inner layer facing the air-filled chamber 106. The inner layer of the second wall 104 contacts the gas in the air-filled chamber, and the outer layer of the second wall 104 faces the outside of the air-filled chamber, that is, contacts the gas outside the air-filled chamber. The outer layer is, for example, a fabric layer made of the above-mentioned material, and the inner layer is, for example, a polymer material layer made of the above-mentioned material, so that the air mattress 10 can be used on both sides. Optionally, the second wall 104 may have a different structure from the first wall 102, for example, the second wall 104 may only include a polymer material layer.
[0058] The sheet-like tension member 108 is disposed in the air-filled chamber 106. The sheet-like tension member 108 may have a single-layer structure or a multi-layer composite structure according to actual needs.
[0059] The sheet-like tension member 108 of the single-layer structure can be a polymer sheet made of a polymer material by processes such as extrusion, blow molding, calendaring, casting or stretching.

The density of the PVC film can be 1.0 g / cm 3 Up to 1.5g / cm 3 In the range of 1.20 g / cm 3 Up to 1.35g / cm 3More preferably, it is about 1.25 g / cm 3 When the single-layer sheet-like tension member 108 is a TPU film, the thickness of the TPU film may be in the range of 0.05 mm to 0.5 mm, preferably in the range of 0.1 mm to 0.3 mm, and more preferably about 0.14 mm. The density of the TPU film may be 1.0 g / cm 3 Up to 1.5g / cm 3 In the range of 1.20 g / cm 3 Up to 1.35g / cm 3 In the range of about 1.20 g / cm 3 . Optionally, the polymer material of the sheet-like tension member 108 may be the same as the material of the polymer material layer of the first wall 102 and / or the second wall 104, so as to facilitate welding of the sheet-like tension member 108 to the first wall 102 and the second wall 104. The sheet-like tension member 108 of a single-layer structure may also be made of a fabric or a non-woven fabric. The fabric may optionally be finely woven or formed into a mesh structure. The fabric may be made of one or more of polyester fibers, polyamide fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, polypropylene fibers, and polyurethane fibers. Non-woven fabrics may include hot-pressed non-woven fabrics, spunlace non-woven fabrics, and needle-punched non-woven fabrics according to the manufacturing process. The non-woven fabric may be made of one or more of polypropylene (PP), polyethylene (PE), and polyester fibers.
[0060] The sheet-like tension member 108 of the multi-layer composite structure can be formed by bonding / combining two or more layers of sheets by gluing, welding or other methods, and the sheet material of each layer can be the polymer sheet, fabric or non-woven fabric as described above. Optionally, the sheet-like tension member 108 of the multi-layer composite structure can be made of cloth-surfaced laminated material or mesh material, wherein "cloth-surfaced laminated material" refers to a double-layer material formed by bonding the fabric or non-woven fabric as described above and the polymer sheet as described above, and "mesh material" refers to a three-layer material formed by bonding two polymer sheets as described above and a mesh cloth sandwiched therebetween.

Thermal convection and thermal radiation are the main heat transfer modes in the air mattress, and the sheet-like tension member with metal plated on the surface has a good function of reflecting thermal radiation, which can reflect the heat radiated by the human body back to the human body, reduce heat loss, and improve the thermal insulation effect of the air mattress. Optionally, both sides of the sheet-like tension member 108 may be plated with metal to further improve the thermal insulation effect of the air mattress. Optionally, the sheet-like tension member 108 with metal plated on the surface includes non-woven fabric or fabric, so as to form a non-dense metal coating on the surface of the sheet-like tension member 108, thereby facilitating welding the sheet-like tension member 108 to the first wall 102 and the second wall 104 by welding. For example, the sheet-like tension member 108 may include one layer made of non-woven fabric or fabric, or the sheet-like tension member 108 may be made of only non-woven fabric or fabric.
[0062] In the illustrated embodiment, the sheet-like tension member 108 is a continuous sheet of material. The sheet-like tension member 108 has a wavy cross-section. The sheet-like tension member 108 is welded alternately to the first wall 102 and the second wall 104 along the length direction L of the air mattress 10. The sheet-like tension member 108 includes a plurality of first sections 112, a plurality of second sections 114, and a plurality of tension sections 116. The plurality of first sections 112 are welded to the first wall 102 in sequence. The plurality of second sections 114 are welded to the second wall 104 in sequence. The plurality of tension sections 116 extend between the corresponding first sections 112 and second sections 114.

Each of the plurality of second segments 114 extends generally parallel to / along the second wall 104. Each of the plurality of tensioning segments 116 extends between the first segment 112 and the second segment 114 adjacent to the tensioning segment.
[0064] When air mattress 10 is inflated, multiple tension sections 116 of sheet-like tension member 108 are tensioned and provide tension to first wall 102 and second wall 104 to limit deformation of air mattress 10 , thereby allowing air mattress 10 to maintain a predetermined shape.
[0065] In the illustrated embodiment, air mattress 10 includes only one sheet-like tension member 108. Optionally, in the inflated state of air mattress 10, the length of sheet-like tension member 108 having a corrugated cross-section is 80% to 100% of the length of air mattress 10, and the width of sheet-like tension member 108 is 50% to 100% of the width of air mattress 10, so as to allow the use of only one sheet-like tension member 108 to provide uniform tension at multiple locations distributed substantially throughout air mattress 10.
[0066] In the illustrated embodiment, a plurality of first segments 112 are arranged at intervals along the length direction L of the air mattress 10, and a plurality of second segments 114 are arranged at intervals along the length direction L of the air mattress 10. The plurality of first segments 112 and the plurality of second segments 114 are arranged alternately in the length direction L of the air mattress 10, and each first segment 112 is connected to two adjacent second segments 114 by two tensioning segments 116.

It is also conceivable that in other embodiments not shown, the sheet-like tension member may be welded alternately to the first wall and the second wall along the width direction W of the air mattress, so that a plurality of first sections are arranged at intervals along the width direction W of the air mattress, and a plurality of second sections are arranged at intervals along the width direction W of the air mattress.
[0068] In the illustrated embodiment, the plurality of first segments 112 are welded to the first wall 102 along a plurality of first weld areas 118. Each of the plurality of first segments 112 is welded to the first wall 102 along a respective one of the first weld areas 118. The plurality of second segments 114 are welded to the second wall 104 along a plurality of second weld areas 120. Each of the plurality of second segments 114 is welded to the second wall 104 along a respective one of the second weld areas 120.

The first segment 112 is partially welded to the first wall 102. The second segment 114 is partially welded to the second wall 104. In this way, the welding area can be avoided from being too large, and the risk of damage to the first wall 102 or the second wall 104 during the welding process is reduced.

Each second welding region 120 includes two linear second welding seams 124, which are located at opposite sides of the second section 114 in the length direction L of the air mattress 10. The first welding seams 122 and the second welding seams 124 are both linear and extend along the width direction W of the air mattress 10.

The width LW2 of each second welding seam 124 accounts for 0.5% to 25% of the width S2 of the second section 114 in the length direction L of the air mattress 10. In some embodiments, the width LW1 of the first welding seam 122 is equal to the width LW2 of the second welding seam 124.

[0074] It is understood that, although in the illustrated embodiment, the first section 112 is welded to the first wall 102 along two linear first weld seams 122, in other embodiments not shown, the first section may be welded to the first wall along more than two linear first weld seams. Although in the illustrated embodiment, the second section 114 is welded to the second wall 104 along two linear second weld seams 124, in other embodiments not shown, the second section may be welded to the second wall along more than two linear second weld seams.
[0075] Since the sheet-like tension member 108 is welded to the first wall 102 along the plurality of first weld seams 122 and welded to the second wall 104 along the plurality of second weld seams 124, stripes are formed on the first wall 102 and the second wall 104. It is contemplated that the spacing between two adjacent first weld seams 122 may be the same or different, thereby forming uniform or non-uniform stripes on the first wall 102. Similarly, the spacing between two adjacent second weld seams 124 may be the same or different, thereby forming uniform or non-uniform stripes on the second wall 104.
[0076] In the illustrated embodiment, each of the plurality of tensioning sections 116 extends between the first wall 102 and the second wall 104. More specifically, each tensioning section 116 extends from a first weld seam 122 of an adjacent first section 112 to a second weld seam 124 of an adjacent second section 114, and the spacing between the first weld seam 122 and the second weld seam 124 determines the height S3 of the tensioning section 116.
[0077] When the air mattress 10 is in an inflated state, the tensioning section 116 and the adjacent first section 112 and the second section 114 together form a substantially Z-shaped structure. The tensioning section 116 and the adjacent first section 112 form a first angle α with each other, and the first angle α is an acute angle. Optionally, the first angle α is greater than or equal to 60° and less than 90°, preferably, greater than or equal to 70° and less than 90°, and more preferably, approximately 85°. The tensioning section 116 and the adjacent second section 114 form a second angle β with each other, and the second angle β is an acute angle. Optionally, the second angle β is greater than or equal to 60° and less than 90°, preferably, greater than or equal to 70° and less than 90°, and more preferably, approximately 85°. The height S3 of the tensioning section 116 together with the first angle α and the second angle β determine the thickness of the air mattress 10 in the inflated state.
[0078] In addition, the first weld seam 122 and the second weld seam 124 adjacent to the tensioning section 116 may be substantially aligned in the thickness direction T of the air mattress 10. The first distance NW1 between the two first weld seams 122 of one first section 112 and the second distance NW2 between the two first weld seams 122 adjacent to each other on two adjacent first sections 112 may be substantially equal. In the inflated state of the air mattress 10, the first wall 102 forms a bulge 113a between the two first weld seams 122 of one first section 112, and the first wall 102 forms a bulge 113b between the two first weld seams 122 adjacent to each other on two adjacent first sections 112. The sizes of the bulge 113a and the bulge 113b may be substantially the same. The third distance NW3 between the two second weld seams 124 of one second section 114 and the fourth distance NW4 between the two second weld seams 124 adjacent to each other on two adjacent second sections 114 may be substantially equal. When the air mattress 10 is inflated, the second wall 104 forms a raised portion 115b between two second weld seams 124 of one second section 114, and the second wall 104 forms a raised portion 115a between two second weld seams 124 that are located in and close to two adjacent second sections 114. The raised portion 115a and the raised portion 115b may be substantially the same size.
[0079] During the manufacturing process of the air mattress 10, the first wall 102, the second wall 104 and the sheet-like tension member 108 can be automatically fed, and then the sheet-like tension member 108 can be alternately welded to the first wall 102 and the second wall 104. By controlling the welding spacing and / or welding position, for example, the spacing between the two adjacent first welding seams 122, the spacing between the two adjacent second welding seams 124, the spacing between the adjacent first welding seams 122 and the second welding seams 124, and the first angle and the second angle can be controlled, thereby controlling the spacing of the stripes formed on the first wall 102 and the second wall 104 and the thickness of the air mattress 10. Compared with the existing air mattresses including multiple drawstrings, during the manufacturing process of the air mattress 10, it is not necessary to manually place the multiple drawstrings in the correct position, thereby improving the production efficiency, and effectively overcoming the phenomenon of drawstring leakage welding and over-welding in the manufacturing process of the existing air mattresses including multiple drawstrings, thereby reducing the product defect rate.
[0080] In some embodiments, the sheet-like tension member 108 can be welded to the first wall 102 and the second wall 104 by high frequency welding. The operating frequency of the high frequency welding can be in the range of 5 MHz to 40 MHz, preferably in the range of 10 MHz to 20 MHz, and more preferably about 15 MHz. The operating pressure of the high frequency welding can be 5 kgf / cm 2 Up to 70kgf / cm 2 In the range of 10 kgf / cm 2 Up to 50kgf / cm 2 More preferably, it is about 32kgf / cm 2 .
[0081] In other embodiments, the sheet-like tension member 108 may be welded to the first wall 102 and the second wall 104 by means of thermocompression welding. The working pressure of the thermocompression welding may be 5 kgf / cm 2 Up to 70kgf / cm 2 In the range of 10 kgf / cm 2 Up to 50kgf / cm 2 More preferably, it is about 32kgf / cm 2 .
[0082] It is understood that the sheet-like tension member 108 can be unfolded to extend substantially along a plane before being welded to the first wall 102 and the second wall 104. In this document, the area of the sheet-like tension member in the aforementioned unfolded state is referred to as the unfolded area of the sheet-like tension member. The ratio of the unfolded area of the sheet-like tension member to the area of the first wall can be in the range of 1.2 to 10, preferably in the range of 1.5 to 5, and more preferably about 2. The ratio of the unfolded area of the sheet-like tension member to the area of the second wall can be in the range of 1.2 to 10, preferably in the range of 1.5 to 5, and more preferably about 2.
[0083] In this context, the sheet-like tension member 108 in the inflatable product 10 is considered to be bent once each time the first angle α or the second angle β is formed. Figure 4B For example, the sheet-like tension member 108 is Figure 4B The portion shown in FIG. 1 is bent 6 times. The ratio of the number of bends of the sheet-like tension member to the length of the inflatable product (i.e., the dimension of the inflatable product in the length direction L) can be in the range of 18 times / m to 66 times / m, preferably in the range of 28 times / m to 56 times / m, preferably about 45 times / m.

It can be understood that the inflatable mattress of the second embodiment has a similar structure to the inflatable mattress of the first embodiment, so the similarities with the inflatable mattress of the first embodiment can be understood with the help of the above detailed description, and no further description is given.

The first section 112 and the second section 114 may have the same width. The first distance NW1 between the two first weld seams 122 of one first section 112 may be smaller than the second distance NW2 between the two first weld seams 122 that are adjacent to each other on two adjacent first sections 112. When the air mattress 10 is inflated, the bulge 113a formed between two first weld seams 122 of one first section 112 of the first wall 102 may be smaller than the bulge 113b formed between two first weld seams 122 of the first wall 102 that are located in and adjacent to two adjacent first sections 112. The third distance NW3 between two second weld seams 124 of one second section 114 may be smaller than the fourth distance NW4 between two second weld seams 124 that are located in and adjacent to two adjacent second sections 114. When the air mattress 10 is inflated, the bulge 115b formed between two second weld seams 124 of the second wall 104 in one second section 114 may be smaller than the bulge 115a formed between two second weld seams 124 of the second wall 104 that are located in and adjacent to two adjacent second sections 114.

The second section 114 is welded to the second wall 104 along the second welding area 120, and the second welding area 120 includes an annular second welding seam 124. In the illustrated embodiment, the first welding seam 122 extends along the periphery of the first section 112, and the second welding seam 124 extends along the periphery of the second section 114.
[0093] It is conceivable that in other embodiments not shown, each first welding area may also include two or more annular first welds, for example, the first welding area includes two annular first welds, one of which surrounds the other annular first weld; similarly, the second welding area may also include two or more annular second welds.
[0094] Fifth embodiment

It can be understood that the inflatable mattress of the fifth embodiment has a similar structure to the inflatable mattress of the first embodiment, so the similarities with the inflatable mattress of the first embodiment can be understood with the help of the above detailed description, and no further description is given.
[0096] Reference Figure 8 and Fig. 9, the difference from the inflatable mattress of the first embodiment is that in the inflatable mattress of the fifth embodiment, the inflatable mattress 10 further includes a heat preservation layer 126 and a connecting sheet 128 disposed in the inflatable chamber 106, and the heat preservation layer 126 and the connecting sheet 128 are disposed between the first wall 102 and the sheet-like tensioning member 108. The heat preservation layer 126 and the connecting sheet 128 may have substantially the same shape and size as the first wall 102 and the second wall 104. The heat preservation layer 126 may be a whole piece of flocculent sheet material and made of fiber. The heat preservation layer 126 may be made of one or more of cotton fiber, wool fiber, viscose fiber, acetate fiber, polyester fiber, polyamide fiber, polyacrylonitrile fiber, polyvinyl alcohol fiber, polypropylene fiber, and polyurethane fiber. The material of the connecting sheet 128 may be the same as the polymer material layer of the first wall 102.

At the location of each first welding region 118, the first wall 102, the connecting piece 128, the thermal insulation layer 126, and the first section 112 of the sheet-like tension member 108 can be welded together from top to bottom. In other words, during welding, the first wall 102, the connecting piece 128, the thermal insulation layer 126, and the sheet-like tension member 108 can be welded together simultaneously along the first welding region 118, so that the thermal insulation layer 126 can be firmly fixed to the first wall 102. It is understood that the thickness of the insulation layer 126 can be compressed after welding at the locations of these first welding areas 118. It is understood that the structure of the sheet-like tension member 108 and the structure of the sheet-like tension member 108 welded to the first wall and the second wall in the above-mentioned embodiment can be applied to this embodiment.

[0100] Sixth embodiment
[0101] Fig.10 and Fig.11 The inflatable product according to the sixth embodiment of the utility model is shown, namely, the inflatable mattress 10. It can be understood that the inflatable mattress of the sixth embodiment has a similar structure to the inflatable mattress of the first embodiment, so the similarities with the inflatable mattress of the first embodiment can be understood with the help of the above specific description, and no further description is given.
[0102] Reference Fig.10 and Fig.11 , the difference from the inflatable mattress of the first embodiment is that the inflatable mattress 10 of the sixth embodiment further includes a third wall 130, and the periphery 103 of the first wall 102 and the periphery 105 of the second wall 104 are connected through the third wall 130. Specifically, the periphery 103 of the first wall 102 is welded to the top edge 131 of the third wall 130, and the periphery 105 of the second wall 104 is welded to the bottom edge 132 of the third wall 130, so that the first wall 102, the second wall 104 and the third wall 130 jointly define the inflation chamber 106. In the illustrated embodiment, the air valve 110 is welded to the first wall 102. In other embodiments not shown, the air valve 110 may also be welded to the second wall 104 or the third wall 130.
[0103] The material of the third wall 130 may be, for example, the same as the polymer material layer of the first wall 102. For example, the third wall 130 may be made of one or more of polyvinyl chloride (PVC), thermoplastic polyurethane elastomer (TPU), polyurethane (PU), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), ethylene-vinyl acetate copolymer (EVA), polyamide (PA) and other suitable polymer materials.
[0104] It can be understood that the structure of the sheet-like tension member 108 in the aforementioned embodiment and the structure in which the sheet-like tension member 108 is welded to the first wall 102 and the second wall 104 can be applied to the present embodiment.

[0106] It can be understood that the various embodiments described above are not exhaustive, and based on the disclosures of the first to sixth embodiments, the present invention also covers a variety of implementation variations that can be easily conceived by those skilled in the art.
[0107] For example, the sixth embodiment is equivalent to adding a third wall on the basis of the first embodiment. It can be understood that the third wall can also be added on the basis of the second to fifth embodiments to form other embodiments not shown.
[0108] For example, in the illustrated embodiment, the first welding region and the second welding region (collectively referred to as welding regions) both include welding seams. It is conceivable that, in addition to the straight and wavy first and second welding seams in the first and third embodiments, welding seams of other shapes, such as broken line welding seams, may also be used. In addition, it is conceivable that, in some embodiments not shown, the welding region may only include a plurality of welding points, and the plurality of welding points may be evenly distributed on the first section or the second section. It is also conceivable that, in other embodiments not shown, the welding region may include a combination of welding seams and welding points.
[0109] For another example, in the illustrated embodiment, the first welding area and the second welding area have the same form, for example, both include a straight welding seam, a wavy welding seam, or an annular welding seam. It is conceivable that in some embodiments not shown, the first welding area and the second welding area may have different forms, for example, the first welding area includes a straight welding seam and the second welding area includes a wavy welding seam, or for another example, the first welding area includes an annular welding seam and the second welding area includes a wavy welding seam, etc. This allows the user to easily distinguish the first wall from the second wall, that is, to easily distinguish the top wall and the bottom wall of the inflatable mattress.
[0110] For another example, although the first to sixth embodiments are all inflatable mattresses, it is conceivable that the concept of the present invention can also be applied to other inflatable products such as inflatable pools, inflatable seats, etc.

However, it is understandable that under the creative idea of the utility model, those skilled in the art can easily make modifications, variations and equivalents of these embodiments according to the disclosed content. For example, a feature shown or described as part of an embodiment can be used together with another embodiment to produce another embodiment.
