Description

Technical Field

[0001] This invention relates to the field of air cushions, and more specifically, to an easily retractable air cushion. Background Technology

[0002] Air mattresses are popular and widely accepted by consumers because they are easy to inflate and easy to store after deflation. They are also widely used in cars, where they can be taken outdoors to be used on grass or placed in the car for resting.

[0003] Ordinary air mattresses, after deflation, simply lie flat in their original position and need to be unfolded and folded for storage, which is time-consuming and laborious, causing inconvenience for consumers. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an air cushion that is easy to store and retract, in order to address the above-mentioned defects of the prior art that require folding during storage and retraction.

[0005] The technical solution adopted by the present invention to solve its technical problem is: to construct an easily deployable air cushion, including an air bladder and a support structure;

[0006] The airbag is provided with an air port to inflate or deflate the airbag.

[0007] The support structure is arranged inside the airbag along a first direction and can extend and retract in the first direction;

[0008] The support structure has a first clearance opening and a second clearance opening arranged on two opposite sides along the first direction, so that when the airbag is deflating, the two opposite sidewalls of the airbag contract and embed into the first clearance opening and the second clearance opening, and drive the support structure to fold in the first direction, closing the first clearance opening and the second clearance opening, so that the airbag contracts in the first direction, and when the airbag is inflated, the support structure extends in the first direction, and the first clearance opening and the second clearance opening open.

[0009] In some embodiments, the support structure includes a first support wall and a second support wall arranged at an angle, and a third support wall and a fourth support wall arranged at an angle, wherein a first clearance opening is formed between the first support wall and the second support wall, and a second clearance opening is formed between the third support wall and the fourth support wall.

[0010] In some embodiments, the outer edges of the first and second support walls adjacent to each of the first clearance openings are movably connected or abut against each other, and the outer edges of the third and fourth support walls adjacent to each of the second clearance openings are movably connected or abut against each other.

[0011] In some embodiments, the first clearance opening and the second clearance opening are staggered in the first direction to form a support structure with a sawtooth or wavy cross-section.

[0012] In some embodiments, the first support wall, second support wall, third support wall, and fourth support wall of the first clearance opening and the second clearance opening corresponding to the position in the first direction are movably connected to each other.

[0013] In some embodiments, a support base capable of folding or unfolding along the first direction is further provided between the first clearance opening and the second clearance opening on both sides to achieve telescopic movement; or,

[0014] A contraction hole is formed between the first and second clearance openings on both sides, which can be folded or unfolded along the first direction to achieve expansion and contraction.

[0015] In some embodiments, a plurality of contraction holes are formed on the support base, and the extension direction of the contraction holes is the same as the extension direction of the first clearance opening and the second clearance opening, so as to contract in the first direction.

[0016] In some embodiments, the width of the contraction hole in the first direction is smaller than the width in the direction from the first clearance opening to the second clearance opening.

[0017] In some embodiments, the support structure includes a plurality of support units arranged side by side along a first direction, and each support unit is provided with a first clearance opening and a second clearance opening.

[0018] In some embodiments, the sidewall of the support structure is provided with a flow hole along the first direction.

[0019] The easily retractable air cushion of the present invention has the following beneficial effects: When the air cushion is deflated and contracted, the first and second clearance openings naturally segment the sidewalls, and the two opposite sidewalls of the air cushion can retract and embed into the first and second clearance openings. During the continued deflating process, the sidewalls of the airbag continue to contract in the first direction, further driving the support structure to fold together in the first direction until the gas inside the airbag is emptied. The sidewalls of the airbag will fold regularly according to the distribution of the first and second clearance openings of the support structure. The contraction ratio in the first direction is large after deflating. When inflating, the unfolding of the sidewalls of the airbag will drive the support structure to unfold again, which facilitates the storage and unfolding of the air cushion and makes it more convenient to use.

[0026] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the air cushion includes an air bladder 1 and a support structure 2. The air bladder 1 is provided with an air port 11 for inflating or deflating gas. Inflating or deflating can be done using an inflation / deflation device, allowing gas to be quickly inflated or deflated. The support structure 2 is disposed inside the air bladder 1 along a first direction A and can extend and retract in the first direction A. The first direction A is usually the length direction, but it can also be the width direction. The air cushion can be an air mattress, an air cushion pillow, an air cushion seat cushion, etc.

[0028] Preferably, in the inflated state, the airbag 1 can be located around the deployed support structure 2, and the support structure 2 can be connected to or separated from the inner wall of the airbag 1. In other embodiments, the length of the airbag 1 in the first direction A can also be greater than the length of the support structure 2 in the first direction A, and after deflation, the two ends of the airbag 1 can be attached to the two ends of the support structure 2.

[0029] In some embodiments, the two opposite sides of the support structure 2 are respectively provided with a first clearance opening B and a second clearance opening C along the first direction A, so that when the airbag 1 is deflating, the two opposite sidewalls of the airbag 1 contract and embed into the first clearance opening B and the second clearance opening C, and drive the support structure 2 to fold in the first direction A, and close the first clearance opening B and the second clearance opening C, so that the airbag 1 contracts in the first direction A, and when the airbag 1 is inflated, the support structure 2 extends in the first direction A, and the first clearance opening B and the second clearance opening C open.

[0030] After the air cushion is inflated, the support structure 2 is located inside and does not affect the use of the air cushion. When the air cushion is deflated and contracted, the first clearance port B and the second clearance port C naturally segment the side wall. The two opposite side walls of the air cushion can then contract and embed into the first clearance port B and the second clearance port C. During the continued deflating process, the side wall of the airbag 1 continues to contract in the first direction A, further driving the support structure 2 to fold together in the first direction A until the gas in the airbag 1 is emptied. The side wall of the airbag 1 will fold regularly according to the distribution of the first clearance port B and the second clearance port C of the support structure 2. The contraction ratio in the first direction A is large after deflating. When inflating, the unfolding of the side wall of the airbag 1 will drive the support structure 2 to unfold again, making it easier to store and unfold the air cushion, making it more convenient to use.

[0031] In some embodiments, the support structure 2 includes a first support wall 21 and a second support wall 22 arranged at an angle, and a third support wall 23 and a fourth support wall 24 arranged at an angle. A first clearance opening B is formed between the first support wall 21 and the second support wall 22, and a second clearance opening C is formed between the third support wall 23 and the fourth support wall 24. The angled first support wall 21 and the angled third support wall 23 and the angled fourth support wall 24 can be distributed on both sides of the airbag 1 to form support, and the sidewall of the airbag 1 is segmented in the first direction A, so that the airbag 1 can contract inward and then fold when deflated, thereby increasing the contraction ratio of the airbag 1. Specifically, in some embodiments, the first support wall 21 and the second support wall 22 can be rotatably connected so as to open to form the first clearance opening B and close to achieve contraction, and the third support wall 23 and the fourth support wall 24 can be rotatably connected so as to open to form the second clearance opening C and close to achieve contraction. Of course, other non-rotational connection methods can also be used, as long as rotation and swing can be achieved.

[0032] Furthermore, in this embodiment, the first support wall 21, the second support wall 22, the third support wall 23, and the fourth support wall 24 corresponding to the first clearance opening B and the second clearance opening C on the first direction A are movably connected to each other, allowing the support structure 2 to extend and retract smoothly and reducing the resistance when the airbag 1 is inflated and deflated. Specifically, the first support wall 21, the second support wall 22, the third support wall 23, and the fourth support wall 24 can be rotatably connected at the joint position, or other non-rotational connection methods can be used, as long as rotation and swing can be achieved.

[0033] In some embodiments, the outer edges of the adjacent first support walls 21 and second support walls 22 at each first clearance opening B are movably connected or abut against each other, and the outer edges of the adjacent third support walls 23 and fourth support walls 24 at each second clearance opening C are movably connected or abut against each other, allowing the adjacent first clearance openings B and second clearance openings C of the support structure 2 to fold in the first direction A, making the folding action smoother. The movable connection can be a rotational connection or a non-rotational connection, as long as it can achieve rotation and swing.

[0034] Furthermore, a contraction hole D is formed between the first clearance opening B and the second clearance opening C on both sides, which can be folded or unfolded along the first direction A to achieve expansion and contraction. In some embodiments, the contraction hole D can be formed by two adjacent first clearance openings B on one side and two adjacent second clearance openings C on the other side, or it can be located between the opposite first clearance openings B and second clearance openings C. In some embodiments, the cross-section of the contraction hole D can be at least square, rhomboid, or elliptical, as long as it can contract in the first direction during air extraction.

[0035] like Figure 3 As shown, in other embodiments, when there is no contraction hole D between the first clearance opening B and the second clearance opening C, the first clearance opening B and the second clearance opening C can be staggered in the first direction A to form a support structure 2 with a serrated or wavy cross section, so that the support structure 2 can be folded in the first direction A.

[0036] Combination Figure 4 As shown, in other embodiments, a support base 25 is provided between the first clearance opening B and the second clearance opening C on both sides, which can be folded or unfolded along the first direction A to achieve telescopic movement. The first support wall 21, the second support wall 22, the third support wall 23, and the fourth support wall 24 can be formed on the support base 25, or they can be respectively set on the support base 25, as long as they can form a structure that can be folded and unfolded in the first direction A.

[0037] Furthermore, a plurality of contraction holes D are formed on the support 25. The extension direction of the contraction holes D is the same as the extension direction of the first clearance port B and the second clearance port C, so that when the airbag 1 is pumped outward, the contraction holes D can be compressed in the first direction A, thereby enabling the support 25 to contract in the first direction A and providing assistance for the airbag 1 to contract in the first direction A.

[0038] Preferably, in this embodiment, the width of the contraction hole D in the first direction A is smaller than the width in the direction from the first clearance opening B to the second clearance opening C, so that when the airbag 1 is deflating, it first contracts in the first direction A, and then the support structure 2 contracts in the first direction A.

[0039] In some embodiments, the first support wall 21, the second support wall 22, the third support wall 23, the fourth support wall 24, and the support base 25 of the support structure 2 can be made of a soft material with a certain thickness and strength, which can provide support for the side walls of the airbag 1 when the airbag 1 is deflated, preventing it from being crushed. Preferably, it can be made of foam or plastic material, so that the support structure 2 will not be crushed when the airbag 1 is deflated, causing failure to contract in the first direction A. After the airbag 1 is inflated and deployed, the support structure 2 can also extend with the airbag 1 and maintain a set shape, forming a first clearance opening B and a second clearance opening C on both sides, respectively, so that the aforementioned contraction action can be repeated when the airbag 1 is deflated.

[0040] Support structure 2 can be an integral structure, such as Figure 5 As shown, in other embodiments, the support structure 2 can also be segmented. The support structure 2 includes a plurality of support units 26 arranged side by side along the first direction A. Each support unit 26 is provided with a first clearance opening B and a second clearance opening C. The support units 26 are spliced ​​and arranged along the first direction A.

[0041] In order to ensure smooth airflow in the spaces separated by the support structure 2, flow holes (not shown) can be provided on the side wall of the support structure 2 along the first direction A, so that the contraction at each position in the first direction A can be synchronized.

[0042] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0043] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
