Description

Technical Field

[0001] This invention relates to an inflatable mat and a method for manufacturing an inflatable mat. Background Technology

[0002] Modern sleeping mats (such as those used for camping) typically consist of an upper and lower layer defining a closed volume. Sleeping mats include valves or openings for inflating the mat, enhancing comfort. It is well known that reflective layers are included within the internal volume of the sleeping mat to improve its thermal performance. These insulating layers help trap heat and reflect it back to the user. Because less heat is transferred through the mat to the ground, its thermal efficiency is increased.

[0003] Beyond achieving the desired thermal performance in a sleeping pad, it's crucial to provide optimal comfort for a restful sleep. Designing a sleeping pad that effectively insulates while also offering user comfort presents a significant challenge in manufacturing bedding solutions. Because the upper and lower layers, as well as the reflective layer, are made of different materials, the insulation layer cannot be heat-sealed or welded to the upper and lower layers.

[0004] The present invention seeks to overcome or at least mitigate one or more problems associated with the prior art. Summary of the Invention

[0005] A first aspect of the invention provides an inflatable pad comprising: an upper outer layer and a lower outer layer defining a substantially enclosed internal volume; and / or at least one valve in selectable fluid communication with the internal volume; and / or at least one insulation layer disposed between the upper and lower outer layers; and / or a plurality of straps, each of the plurality of straps extending between the upper and lower outer layers and directly connected to the upper and lower outer layers; and / or a plurality of strip members, each of the plurality of strip members configured to secure the insulation layer to one of the upper or lower outer layers.

[0006] Advantageously, providing an insulation layer helps to capture heat and reflect it back to the user, thereby improving insulation against the ground. Since the amount of heat energy transferred through the mat is reduced, the thermal efficiency of the inflatable mat is increased.

[0007] When the inflatable mat is in its inflatable configuration, multiple tie elements help maintain the desired spacing between the upper outer layer and the lower outer layer to maintain its approximate planar shape with the desired thickness. Strip-shaped components help secure the insulation layer relative to the upper and lower outer layers, thus holding the insulation layer in the proper position where it effectively suppresses heat loss when the mat is in its inflatable configuration.

[0008] Providing tie-in and strip components to perform the above functions can help improve manufacturing simplicity while maintaining the ideal shape and positioning of the insulation layer of the inflatable pad in the inflatable configuration.

[0009] Optionally, the multiple assemblies are each separate from each other. Optionally, the multiple strip components are each separate from the multiple assemblies and are also separate from each other.

[0017] Optionally, each of the plurality of components is connected to the upper outer layer at an upper connection point and to the lower outer layer at a lower connection point, wherein the upper connection point and the lower connection point are laterally aligned.

[0018] Advantageously, the laterally aligned connection points provide support and shape in the lateral direction relative to the upper and lower outer layers, which helps to support the user's weight.

Optionally, each strip member extends through more than one of the plurality of holes in the at least one insulation layer.

[0035] Optionally, at least one insulation layer includes an upper insulation layer and a lower insulation layer, the upper insulation layer being connected to an upper outer layer via a plurality of upper strip members, and the lower insulation layer being connected to a lower outer layer via a plurality of lower strip members.

[0036] Advantageously, providing more than one insulation layer helps to facilitate additional heat capture and reflect heat back to the user, thereby reducing the thermal energy transferred through the inflatable pad and improving the thermal efficiency of the inflatable pad.

[0037] Optionally, the first connection point and the second connection point of each of the plurality of upper strip components are located between the upper outer layer and the upper insulation layer, and / or the first connection point and the second connection point of each of the plurality of lower strip components are located between the lower outer layer and the lower insulation layer.

[0041] Optionally, the hole defines the width, and the minimum width of the neck is substantially equal to the width of the hole.

[0042] Optionally, the fitting includes a general hourglass shape defining the neck.

[0043] Advantageously, the hourglass shape allows the neck to hold the insulation layer in the correct position when the air mattress is in the intended use orientation and when the air mattress is inverted. Furthermore, the hourglass structure is easy to manufacture and assemble.

[0044] Optionally, at least one insulation layer includes a plurality of holes, each of which is configured to receive the neck of a corresponding fitting.

[0052] Advantageously, the upper outer layer, lower outer layer, and at least one insulation layer are made of different materials, which means that these layers can serve the dual function of improving the thermal efficiency of the inflatable pad and providing support for the user during use.

[0053] Furthermore, because the upper and lower insulation layers are made of different materials than the upper and lower outer layers, they cannot be heat-sealed or welded to their respective upper or lower outer layers. Thus, tie-on and strip components help overcome the problem of how to connect / position the insulation layers to the upper and lower outer layers.

[0060] Optionally, the neck is defined with a minimum width, and the minimum width is positioned at intervals between the upper and lower ends of the fitting.

[0068] Optionally, the inflatable pad includes multiple straps, each of which extends between the upper outer layer and the lower outer layer and is directly connected to the upper outer layer and the lower outer layer.

[0072] Advantageously, providing multiple separate ties and / or separate strips improves the ease of manufacturing the inflatable pad compared to a continuous arrangement of, for example, ties and / or strips.

[0073] Alternatively, the tie element is oriented substantially laterally relative to the strip component.

[0074] Advantageously, providing tie elements transverse to the strip member helps to provide support and shape for the inflatable pad in more than one direction.

[0075] Alternatively, when the inflatable pad is in the inflatable configuration, the multiple components are generally laterally oriented relative to the upper and lower outer layers.

[0079] Optionally, each of the plurality of components is connected to the upper outer layer at an upper connection point and to the lower outer layer at a lower connection point, wherein the upper connection point and the lower connection point are laterally aligned.

Optionally, the first connection point and the second connection point are longitudinally aligned.

[0082] Advantageously, the first and second connection points allow at least one insulation layer to be connected to the upper or lower outer layer. Furthermore, the longitudinally aligned connection points provide support and shape in the longitudinal direction.

[0083] Optionally, multiple components are arranged in a multi-row array. Optionally, each row extends in a direction substantially perpendicular to the central longitudinal axis of the inflatable pad.

[0084] Advantageously, providing multiple rows of arrays offers uniform support and helps maintain the shape of the inflatable pad along each row. Furthermore, the rows are easy to manufacture.

[0115] Figures 5A to 5C This is an exploded view showing an alternative embodiment of the inflatable pad according to the present invention. Detailed Implementation

[0116] First refer to Figure 1 The inflatable pad according to the present invention is generally designated as 10. The term "upper" refers to the side of the inflatable pad facing away from the ground (i.e., substantially upward) when the inflatable pad 10 is in the intended orientation for user use. The term "lower" refers to the side of the inflatable pad facing the ground (i.e., substantially downward) when the inflatable pad 10 is in the intended orientation for user use. For ease of understanding, the following description is based on the inflated state of the inflatable pad 10. It should be understood that the relative positions of the following components may change when deflated for storage or transportation.

[0117] The inflatable cushion 10 includes an upper outer layer 12a and a lower outer layer 12b defining a substantially enclosed internal volume; at least one valve 14 in selective fluid communication with the internal volume; at least one thermal insulation layer 16a-c disposed between the upper outer layer 12a and the lower outer layer 12b; a plurality of straps 18 extending between and directly connected to the upper outer layer 12a and the lower outer layer 12b; and a plurality of strip members 20a, 20b, each of which is configured to connect at least one thermal insulation layer 16a, 16c to one of the upper outer layer 12a or the lower outer layer 12b. It should be understood that in some embodiments, the strip members 20a, 20b may be omitted, as will be described in more detail below.

[0118] The inflatable pad 10 is inflated into its inflatable configuration by supplying air to the enclosed internal volume through valve 14. Valve 14 can be connected to a pressurized air source, such as a pump, or air can be supplied to valve 14 by the user manually blowing air into the inflatable pad 10. Figure 1 In one embodiment, valve 14 is located on the upper outer layer 12a, facing the periphery; however, in an alternative embodiment, valve 14 may be located on the lower outer layer 12b, or on the seam between the upper outer layer 12a and the lower outer layer 12b. It should be understood that valve 14 may be any suitable valve, such as a Boston valve or a pinch valve, or valve 14 may be any form of closable opening.

[0119] The upper outer layer 12a and the lower outer layer 12b are made of a composite material of a flexible textile sheet material (e.g., nylon or polyester material disposed on the outermost layer) and a flexible, airtight plastic sheet material (e.g., thermoplastic polyurethane (TPU) material) on the innermost layer. These materials provide both user comfort and durability and lightweight. The upper outer layer 12a and the lower outer layer 12b can be joined together using any suitable manufacturing process, such as ultrasonic welding, heat sealing, or the use of adhesives. It should be understood that in other embodiments, the upper outer layer 12a and the lower outer layer 12b can be made of any suitable material known in the art.

[0120] The upper outer layer 12a defines a substantially flat surface for directly supporting the user's weight when the user lies on the inflatable mat. The lower outer layer 12b defines a substantially flat surface for contacting the ground during use. When the inflatable mat 10 is in its inflated configuration, the upper outer layer 12a and the lower outer layer 12b are substantially parallel.

[0121] The upper outer layer 12a and the lower outer layer 12b extend along the longitudinal axis aa of the inflatable mat 10. This roughly conforms to the proportions / shape of the user (i.e., a human), thus providing the user with a comfortably shaped inflatable mat 10 for sleeping. It should be understood that in some embodiments, the upper outer layer 12a and the lower outer layer 12b may be formed from multiple upper outer layers and multiple lower outer layers, respectively. For example, the upper outer layer 12a and / or the lower outer layer 12b may each be formed from two or more upper outer layers 12a or two or more lower outer layers 12b, for example, from three or more upper outer layers 12a or three or more lower outer layers 12b.

[0122] At least one insulation layer 16a-c is made of a different material than the upper outer layer 12a and the lower outer layer 12b to insulate against radiant heat. The insulation layer also helps reduce heat loss due to convection. Figures 1 to 4 In one embodiment, at least one insulation layer is made of a material that reflects radiant heat, such as a woven or nonwoven fabric substrate coated with a metallic material (e.g., aluminum or titanium), such as a proprietary “TILT” (thermal ion lining technology) material. In an alternative embodiment, at least one insulation layer 16a-c can be any suitable sheet of insulating material, for example, a sheet of foam material if a less compact pad is acceptable when deflated.

[0123] These insulation layers 16a and 16c are made of materials that cannot be heat-sealed or welded to the corresponding upper outer layer 12a or lower outer layer 12b. For example, even if the substrate can be heat-sealed, the metallic coating typically hinders interlayer fusion. Thus, the tie 18 and the strip members 20a and 20b help to properly position the upper insulation layer, the lower insulation layer, and the intermediate insulation layer 16a-c relative to the upper outer layer 12a and the lower outer layer 12b.

[0124] exist Figures 1 to 4 In the illustrated embodiment, at least one insulation layer 16a-c includes an upper insulation layer 16a, a lower insulation layer 16c, and a middle insulation layer 16b. The upper insulation layer 16a is secured to the upper outer layer 12a by a plurality of upper strip members 20a, the lower insulation layer 16c is secured to the lower outer layer 12b by a plurality of lower strip members 20b, and the middle insulation layer 16b is located between the upper insulation layer 16a and the lower insulation layer 16c. Providing multiple insulation layers 16a-c helps to promote additional heat reflection back to the user and reduce heat loss through convection, thereby reducing the thermal energy transferred through the inflatable pad 10 and improving the thermal efficiency of the inflatable pad 10. In this embodiment, the insulation layers 16a-c are made of substantially the same material, but this is not necessary in other embodiments.

[0125] It should be understood that, in alternative embodiments, any suitable number of insulation layers 16a-c can be used, such as one, two, or four insulation layers 16a-c. The number of insulation layers 16a-c can depend on the season in which the air mattress 10 is expected to be used. An air mattress 10 for summer use may have fewer insulation layers 16a-c, such as one insulation layer 16a-c, while an air mattress 10 for winter use may have more insulation layers 16a-c, such as three or four insulation layers 16a-c.

[0126] The insulation layers 16a-c extend over most of the area covering the inflatable pad 10, for example, over essentially the entire area covering the inflatable pad 10. This helps to improve the uniformity of insulation of the inflatable pad 10. When the inflatable pad 10 is in an inflated configuration, the intermediate layer 16b is approximately equidistant from the upper outer layer 12a and the lower outer layer 12b, as will be described in more detail below.

[0127] The upper insulation layer 16a and the lower insulation layer 16c each include a plurality of fastener holes 22, each fastener hole 22 being configured to accommodate a fastener 18 passing through it, such as Figure 2 and 3 As shown. Furthermore, in Figures 1 to 4 , Figure 5A and Figure 5B In one embodiment, the upper insulation layer 16a and the lower insulation layer 16c each include a plurality of strip-shaped holes 24 configured to accommodate corresponding strip-shaped components 20a, 20b passing through them. The intermediate insulation layer 16b includes a plurality of holes 26 configured to accommodate fasteners 18 passing through it. In this embodiment, the fastener holes 22 of the upper insulation layer 16a and the lower insulation layer 16c are each laterally aligned, and each hole 26 in the intermediate insulation layer 16b is laterally aligned with each fastener hole 22 of the upper insulation layer 16a and the lower insulation layer 16c to accommodate vertically arranged fasteners 18. In other embodiments, the fasteners 18 may be at an angle, and in this case, the holes 22 and 26 may not be aligned. The arrangement of the fasteners 18 and strip-shaped components 20a, 20b passing through the holes will be described in more detail below.

[0128] Each of the multiple ties 18 is separate from each other. Each of the multiple strip components 20a, 20b is separate from each other and also separate from each of the multiple ties 18. In other words, each of the multiple ties 18 and each of the multiple strip components 20a, 20b is an independent entity. For example, providing multiple separate ties 18 and separate strip components 20a, 20b helps to improve the ease of manufacturing the inflatable pad 10 compared to a continuous arrangement of ties 18 and / or strip components 20a, 20b. This arrangement also increases structural flexibility, such as changing the number and position of the insulation layers 16a-c.

[0129] like Figure 1 and Figure 4 As shown, multiple tie members 18 and multiple strip members 20a, 20b are arranged in a multi-row array. In this embodiment, each row of tie members 18 extends along a direction substantially perpendicular to the central longitudinal axis aa of the inflatable pad 10, and the multiple rows of strip members 20a, 20b extend longitudinally along the inflatable pad 10 in an alternating manner. Providing a multi-row array provides uniform support and helps maintain the shape of the inflatable pad 10 along each row. Furthermore, rows are a structure that is easy to manufacture. Figures 1 to 4 In this embodiment, 25 rows of ties 18 and 5 rows of strips 20a, 20b are provided. However, it should be understood that any suitable number of rows can be provided, each row having any suitable number of ties 18 and / or strips 20a, 20b, for example, depending on the length or width of the inflatable pad 10. Adjacent rows of ties 18 are longitudinally offset. Adjacent rows of strips 20a, 20b are laterally offset. This helps to provide support over a larger surface area of ​​the inflatable pad 10 for a given number of ties 18 or strips 20a, 20b.

[0130] Each of the multiple strip components 20a, 20b is located between adjacent tie components 18. Some strip components 20a, 20b are located between longitudinally adjacent tie components 18, and some strip components 20a, 20b are located between laterally adjacent tie components 18.

[0131] It should be understood that the arrangement of the tie 18 and the strip components 20a, 20b shown in the figure (e.g.) Figure 1 and 4 The arrangement shown is exemplary. In alternative embodiments, each row of strip members 20a, 20b and / or tie members 18 may extend in a direction substantially parallel to the longitudinal axis aa of the inflatable pad 10. It should be understood that in alternative embodiments, the tie members 18 and / or strip members 20a, 20b may be arranged in any suitable manner, such as a diamond arrangement of the tie members 18 and / or strip members 20a, 20b.

[0132] When the air mattress 10 is in its inflatable configuration, the fastener 18 helps to support the upper outer layer 12a relative to the lower outer layer 12b. It should be understood that the fastener 18 is located within the enclosed internal volume of the air mattress 10, specifically connecting the inner surfaces of the upper outer layer 12a and the lower outer layer 12b. When the air mattress 10 is inflated, the upper outer layer 12a and the lower outer layer 12b are forced apart by the air pressure within the enclosed volume. The fastener 18 acts in a tension manner, maintaining the upper outer layer 12a and the lower outer layer 12b at the desired distance from each other, thereby providing a comfortable and stable shape for the user to lie on. Thus, when the air mattress 10 is in its inflatable configuration, the fastener 18 is under tension.

[0133] The tie 18 makes the surfaces of the upper outer layer 12a and the lower outer layer 12b substantially flat, so that the user can comfortably sleep on the upper outer layer 12a and the lower outer layer 12b can be supported by the ground.

[0134] In this embodiment, component 18 is provided as a single sheet of flexible heat-welding material. This can be a plastic sheet—for example, thermoplastic polyurethane (TPU) material. Component 18 extends between the upper outer layer 12a and the lower outer layer 12b. Figure 2 As shown, the tie 18 is generally oriented laterally relative to the strip members 20a and 20b. Furthermore, when the mat is in an inflatable configuration, the tie 18 is generally oriented laterally relative to the upper outer layer 12a and the lower outer layer 12b. This lateral orientation of the tie 18 helps to provide support and shape for the inflatable mat 10 in a direction generally lateral to the upper outer layer 12a and the lower outer layer 12b (i.e., in use, in the direction opposite to the load applied by the user to the upper outer layer 12a). For example, the tie 18 can be a beam member or a column member.

[0135] Each component 18 is directly connected to the upper outer layer 12a at the upper connection point 28a, and directly connected to the lower outer layer 12b at the lower connection point 28b, such as Figure 3 As shown. The upper connection point 28a and the lower connection point 28b are formed in the folded lip or flange 29a, 29b at the free end of the assembly 18, and they form a surface contact relationship with the inner surface of the corresponding outer layers 12a, 12b.

[0136] Thus, the upper connection point 28a and the lower connection point 28b connect the opposite upper and lower ends of the assembly 18 to the corresponding upper outer layer 12a or lower outer layer 12b. The assembly 18 is heat-sealed or welded at the upper connection point 28a and the lower connection point 28b. The upper connection point 28a and the lower connection point 28b can be strip-shaped or line-shaped connection points, as shown in the figure.

[0137] When the air cushion 10 is inflated, the upper connection point 28a and the lower connection point 28b are laterally aligned. The upper connection point 28a and the lower connection point 28b are aligned with the fastening holes 22 of the upper insulation layer 16a and the lower insulation layer 16c, and with the hole 26 of the middle insulation layer 16b. Thus, each fastener 18 extends laterally from the upper connection point 28a, through the fastening hole 22 of the upper insulation layer 16a, through the hole 26 of the middle insulation layer 16b, and through the fastening hole 22 of the lower insulation layer 16c to reach the second connection point 18b. The size of the fastening holes 22 is designed to provide adequate clearance around the lip 29a for assembly, but not so large as to compromise the insulation quality.

[0138] It should be understood that in embodiments where the upper insulation layer 16a and the lower insulation layer 16c are omitted, each component 18 can extend laterally from the upper connection point 28a through the hole 26 in the middle insulation layer 16b and reach the lower connection point 28b.

[0139] like Figure 3 As shown, in this embodiment, each of the plurality of ties 18 includes a neck 30. The neck 30 defines a minimum width of the corresponding tie 18, and this minimum width is positioned spaced apart from the upper and lower ends of the tie 18. Figure 3 In this embodiment, the minimum width is substantially located at the center of the strip member 18 in the lateral direction. In other words, the minimum width is equidistant from the upper and lower ends of the tie member 18, or equidistant from the upper outer layer 12a and the lower outer layer 12b. The tie member 18 is substantially planar. In this embodiment, the tie member 18 has a generally hourglass shape defining the neck 30. In other words, the tie member 18 tapers inward from the upper end (or upper connection point 28a) and the lower end (or lower connection point 28b) toward the neck 30. The taper is substantially linear.

[0140] It should be understood that, in alternative embodiments, the tie 18 can be any suitable shape defining the neck 30, such as curved or stepped. In some embodiments, the tie 18 may include more than one neck 30 for laterally positioning more than one intermediate thermal insulation layer 16b. The tie 18 may taper inward and outward to define more than one neck 30. It should be understood that the tie 18 may be configured as more than one, for example, as two pieces. These two pieces may be heat-sealed or welded together, for example, at the neck 30.

[0141] The aperture 26 of the intermediate heat insulation layer 16b is sized to be fixed around the neck 30, thereby positioning the intermediate layer 16b relative to the tie 18 in a direction substantially transverse to the upper outer layer 12a and the lower outer layer 12b when the inflatable pad 10 is in an inflatable configuration. It should be noted that in embodiments where only the intermediate heat insulation layer 16b is provided, the intermediate heat insulation layer 16b may also be alternatively referred to as the heat insulation layer 16b. The aperture 26 defines a width, the minimum width of the neck 30 being substantially equal to the width of the aperture 26. This can be understood as the width of the aperture 26 being up to 20% larger than the minimum width of the neck 30, for example, up to 10% larger. Because the minimum width of the neck 30 is spaced apart from the upper and lower ends of the tie 18, the intermediate layer 16b is positioned relative to the tie 18 regardless of the orientation of the inflatable pad 10 (i.e., regardless of whether the upper outer layer 12a and the lower outer layer 12b are reversed).

[0142] It should be understood that in embodiments where the upper insulation layer 16a and / or the lower insulation layer 16c are omitted, only the upper strip member 20a, only the lower strip member 20b, or both the upper strip member 20a and the lower strip member 20b may be omitted. Therefore, some embodiments of the inflatable cushion 10 may only include the tie 18. The upper strip member 20a and the lower strip member 20b have substantially the same structure. Therefore, the term "strip member" will be used below to refer to the upper strip member 20a and the lower strip member 20b.

[0143] When the inflatable pad 10 is in its inflatable configuration, the strip members 20a and 20b help support the upper insulation layer 16a and the lower insulation layer 16c relative to the upper outer layer 12a and the lower outer layer 12b. It should be understood that the strip members 20a and 20b are located within the enclosed internal volume of the inflatable pad 10, i.e., connected to the inner surfaces of the upper outer layer 12a and the lower outer layer 12b. Each of the plurality of strip members 20a and 20b extends from the corresponding upper outer layer 12a or lower outer layer 12b through at least one insulation layer 16a or 16c and returns to the corresponding upper outer layer 12a or lower outer layer 12b of the corresponding upper outer layer 16a or lower outer layer 16c to connect the upper insulation layer 16a or lower insulation layer 16c to the corresponding upper outer layer 12a or lower outer layer 12b. It should be understood that when the inflatable pad 10 is in the inflatable configuration, the strip members 20a, 20b typically extend from the upper outer layer 12a or the lower outer layer 12b in a shallow U-shape and pass through the upper insulation layer 16a or the lower insulation layer 16c, thereby holding the respective insulation layer in its desired position.

[0144] When the air cushion 10 is in the inflatable configuration, each of the multiple strip components 20a and 20b is oriented substantially parallel to the central longitudinal axis aa of the air cushion 10.

[0145] Each of the multiple strip-shaped components 20a, 20b is formed of a flexible sheet and defines opposing planes. One plane faces the upper outer layer 12a, and the other plane faces the lower outer layer 12b. Figure 4 As shown, when viewed in a plan view, each of the multiple strip components 20a and 20b is essentially linear.

[0146] Multiple strip-shaped components 20a, 20b are directly connected to the corresponding upper outer layer 12a or lower outer layer 12b at a first connection point 32a and a second connection point 32b, with the second connection point 32b spaced apart from the first connection point 32a. When the inflatable cushion 10 is configured for use, the first connection point 32a can be axially aligned with the second connection point 32b, such as... Figure 4As shown. The first connection point 32a and the second connection point 32b can be dots or dashed lines. In an alternative embodiment, the first connection point 32a and the second connection point 32b can be aligned in any suitable direction, such as laterally aligned. The first connection point 32a and the second connection point 32b are located at opposite ends of each strip member 20a, 20b. In other words, the ends of the strip members 20a, 20b are connected to the upper outer layer 12a and the lower outer layer 12b.

[0147] The strip components 20a and 20b are heat-sealed or welded to the corresponding upper outer layer 12a or lower outer layer 12b at the first connection point 32a and the second connection point 32b. In this way, the first connection point 32a and the second connection point 32b firmly fix the upper insulation layer 16a and the lower insulation layer 16c to the corresponding upper outer layer 12a and lower outer layer 12b without heat-sealing or welding the upper insulation layer 16a or the lower insulation layer 16c to the upper outer layer 12a or the lower outer layer 12b.

[0148] The first connection point 32a and the second connection point 32b are at least partially laterally aligned with the strip-shaped holes 24 of the corresponding upper insulation layer 16a or lower insulation layer 16c. This facilitates manufacturing because the strip-shaped components 20a, 20b can be heat-sealed or welded to the upper outer layer 12a or lower outer layer 12b through the strip-shaped holes 24, thereby connecting the upper insulation layer 16a or lower insulation layer 16c to the corresponding upper outer layer 12a or lower outer layer 12b via the strip-shaped components 20a, 20b.

[0149] Each strip component 20a, 20b extends through more than one of the plurality of strip holes 24 in the corresponding upper insulation layer 16a or lower insulation layer 16c. For example, each strip component 20a, 20b may extend through adjacent strip holes 24. Thus, each strip component 20a, 20b extends from the first connection point 32a, through the strip holes 24, and is located below the corresponding upper insulation layer 16a or lower insulation layer 16c, then through adjacent holes 24 in the upper insulation layer 16a or lower insulation layer 16c, and returns to the second connection point 32b. It should be understood that in some embodiments, the strip component 24 may extend through more than two strip holes 24. Each strip component 20a, 20b extends only through the upper insulation layer 16a or lower insulation layer 16b. This differs from the tie 18, which may extend through multiple insulation layers 16a-c.

[0150] The manufacturing method of the inflatable cushion 10 will now be described. An upper outer layer 12a and a lower outer layer 12b are provided. As described above, the upper outer layer 12a and the lower outer layer 12b can be formed from more than one layer. At least one heat insulation layer 16a-c is provided, such as an upper heat insulation layer 16a, a lower heat insulation layer 16c, and a middle heat insulation layer 16b. A plurality of tie members 18 and a plurality of strip members 20a, 20b are provided, such as an upper strip member 20a and a lower strip member 20b, having substantially the same structure as described above.

[0151] The upper insulation layer 16a is secured to the upper outer layer 12a by a plurality of upper strip members 20a. The lower insulation layer 16b is secured to the lower outer layer 12b by lower strip members 20b. The strip members 20a and 20b are located in strip holes 24 and are heat-sealed or welded to the upper outer layer 12a or the lower outer layer 12b at a first connection point 32a and a second connection point 32b. The intermediate insulation layer 16b is located on a neck 30 such that a hole 26 accommodates a neck 30 of a tie member 18. Each tie member 18 is connected to both the upper outer layer 12a and the lower outer layer 12b such that each tie member 18 extends between the upper outer layer 12a and the lower outer layer 12b, and the insulation layer 16b is located between the upper outer layer 12a and the lower outer layer 12b. The tie members 18 are heat-sealed or welded at upper connection points 28a and lower connection points 28b. The upper outer layer 12a and the lower outer layer 12b can then be secured, for example, by heat sealing, welding or adhesive at their periphery, to form the inflatable cushion 10.

[0152] Figures 5A to 5C An alternative embodiment of the inflatable pad 10 with an alternative number of insulation layers 16a-c is shown. Figure 5A In this embodiment, an upper insulation layer 16a and a lower insulation layer 16b are provided (i.e., there are two insulation layers 16a and 16c). Therefore, in this embodiment, there is no insulation layer 16b around the neck 30. Therefore, it is conceivable that the neck 30 can be omitted.

[0153] exist Figure 5B In this embodiment, an upper insulation layer 16a and a middle insulation layer 16b are provided. In this embodiment, "middle" means that the insulation layer 16b is located on the neck 30, or does not include the strip-shaped members 20a, 20b extending through it. Therefore, in this embodiment, the lower strip-shaped member 20b is omitted. It should be understood that in other alternative embodiments, only the middle insulation layer 16b and the lower insulation layer 16c may be provided, while the upper strip-shaped member 20b may be omitted.

[0154] Figure 5C An alternative embodiment in which only one insulation layer 16a is provided is shown. As described above, the inflatable pad 10 of this embodiment can be used in summer / higher temperatures. Figure 5CThe implementation includes: an upper outer layer 12a and a lower outer layer 12b, the upper outer layer 12a and the lower outer layer 12b defining a substantially enclosed internal volume; at least one valve, the at least one valve being in selective fluid communication with the internal volume; at least one thermal insulation layer 16b, the at least one thermal insulation layer 16b being disposed between the upper outer layer 12a and the lower outer layer 12b; and a plurality of straps 18, each of the plurality of straps 18 extending between the upper outer layer 12a and the lower outer layer 12b and being directly connected to the upper outer layer 12a and the lower outer layer 12b, wherein each strap 18 includes a neck 30, and wherein at least one thermal insulation layer 16b includes an aperture 24, the aperture being sized to be fixed around the neck 30 so as to position the thermal insulation layer 16b relative to the straps 18 in a direction substantially transverse to the upper outer layer 12a and the lower outer layer 12b when the inflatable pad 10 is configured for use.

[0155] It should be understood that the above regarding Figures 1 to 4 The teachings described are applicable Figures 5A to 5C The implementation method.

[0156] Although the teachings have been described above with reference to one or more preferred embodiments, it should be understood that various changes or modifications may be made without departing from the scope defined in the appended claims. For example, the lengths of the fasteners may not be equal. For example, the fasteners at the sides may be longer than the fasteners in the middle. This makes the sides of the mat thicker than the middle, thus helping to position the user on the mat during sleep. Although a sleeping mat has been described, the above-described structure can also be used for other articles, such as pillows or cushions, which should also be understood to be included in the term "inflatable mat".
