Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and in particular to an air bag assembly for a massage leg wrap. Background Technology

[0002] Currently, most airbag products on the market use single-layer or multi-layer airbags. When using these products, the gaps between the layers cause a discontinuity between the airbags, creating a noticeable "step-like" feeling on the surface where the body contacts the airbag. Users will frequently experience localized discomfort, uneven pressure distribution, and an overall lack of fit, resulting in a poor user experience. Furthermore, the noticeable discontinuity on the surface after the airbag is inflated affects its appearance. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an air bag component for a massage leg wrap, which aims to fill the gaps between air bags, better connect them, and improve massage comfort.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An airbag assembly for a massage leg wrap is used to wrap around a user's legs and massage the legs by inflating and deflating them. It is connected to an air valve and an air pump via an air tube. The assembly includes an inner wall, an outer wall, and a partition. The inner and outer walls are connected to each other to form a cavity for containing gas. The partition is inclinedly disposed in the cavity and divides the cavity into several non-communicating support areas. Each support area is provided with an air nozzle. The air nozzle is connected to the air valve and the air pump via an air tube. When two adjacent support areas are inflated, they overlap in the direction facing the user's legs, so that the support surfaces of two adjacent support areas transition smoothly.

[0006] Furthermore, it also includes a zipper, which is located at the junction of the inner and outer walls. When the zipper is closed, the inner and outer walls can wrap around the user's legs.

[0007] Furthermore, the partitions between each pair of adjacent support zones are set obliquely in the same direction.

[0008] Furthermore, the area of ​​the inner wall is larger than the area of ​​the outer wall, so that when inflated, the support area expands more towards the user's legs.

[0009] Furthermore, several of the support regions are arranged along a straight line or a curve.

[0010] Furthermore, after the several support areas are inflated, the support surfaces of the support areas are in the same plane or form a smooth curved surface.

[0011] Furthermore, each of the aforementioned support areas is provided with an inflation / deflation port.

[0012] Furthermore, the air bag is made of a flexible material, including thermoplastic polyurethane or polyvinyl chloride.

[0013] The beneficial effects of this utility model are:

[0014] 1. The present invention proposes an air bag assembly for a massage leg wrap. By setting a smooth transition of the support surface of the support area, it completely eliminates the gap and depression between the traditional parallel air bags. When the air is inflated sequentially in a predetermined direction, the non-overlapping area of ​​the later inflated support area can fill the gap of the overlapping area of ​​the earlier inflated support area, forming a smooth support plane, better connection, and improving massage comfort.

[0015] 2. The air bag assembly for a massage leg wrap proposed in this utility model, through the alternating superposition of support areas, allows pressure to be transmitted to adjacent air bags along the oblique partition, dispersing the concentrated stress points. After inflation, the air bags in the covered area lock each other, suppressing overall lateral deformation.

[0016] 3. The present invention proposes an air bag assembly for a massage leg wrap, wherein each support area is provided with an independent inflation / deflation port, and the user can adjust the air pressure of each chamber individually, thereby adjusting the shape of the support surface.

[0023] The following is combined with Figure 1-4 This utility model will be described in detail.

[0024] An airbag component for a massage leg wrap, such as Figure 1-2 As shown, this device is used to wrap around the user's legs and massage them by inflating and deflating air. It is connected to an air valve and an air pump via an air tube and includes an inner wall, an outer wall 201, and a partition 202. The inner wall and outer wall 201 are connected to each other to form a cavity for containing gas. The partition 202 is inclinedly disposed in the cavity and divides the cavity into several non-communicating support areas. Each support area is provided with an air nozzle, which is connected to an air valve and an air pump via an air tube. When two adjacent support areas are inflated, they overlap in the direction towards the user's legs, so that the support surfaces 40 of two adjacent support areas transition smoothly.

[0025] The airbag assembly comprises an inner wall and an outer wall 201 made of flexible material, which are heat-sealed at their edges to form a sealed cavity. Multiple inclined partitions 202 are arranged within the cavity, dividing it into several independent support areas, each with its own air nozzle. When the air pump inflates a specific support area through the air tube, the airbag expands towards the leg. Due to the inclined design of the partitions 202, the expanded portions of adjacent support areas overlap vertically on the leg, resulting in a stepped overlap of the contact surfaces of the two support areas. This eliminates gaps or sharp edges between the support surfaces 40, achieving a smooth transition of massage pressure on the leg.

[0026] In this embodiment, a zipper is also included. The zipper is located at the connection between the inner wall and the outer wall 201. When the zipper is closed, the inner wall and the outer wall 201 can wrap around the user's legs.

[0027] A zipper is added at the side connection between the inner wall and the outer wall 201. When the zipper is open, the air bag is flat and easy to wear. When the zipper is closed, the inner wall wraps around the legs to form a cylindrical structure, while the outer wall 201 forms an external restraint layer. The two maintain a close fit to the legs through the tension of the zipper, while ensuring that the shape of the air bag is stable and does not shift when inflated.

[0028] In this embodiment, the partitions 202 between each pair of adjacent support areas are obliquely arranged in the same direction. The oblique partitions 202 are arranged in a uniform direction, and all partitions 202 are parallel to each other with a fixed tilt angle. When the controller activates the support areas in sequence, the inflated airbags form a continuous directional wave along the leg axis.

[0029] In this embodiment, the area of ​​the inner wall is larger than the area of ​​the outer wall 201, so that during inflation, the support area expands more towards the user's legs. The inner and outer walls 201 of the air bag adopt an asymmetrical design: the inner wall has a large area, while the outer wall 201 has a rectangular, conventional area. After the two are connected, the inner wall forms a reserve of excess material. During inflation, the inner wall, due to its greater material redundancy, preferentially expands towards the legs to form a deep-pressure massage surface, while the outer wall 201, with its taut material, restricts outward expansion, forcing the expansion force to act on the muscle tissue.

[0030] In this embodiment, a plurality of air bags are connected in sequence, and each air bag constitutes the support area; or, the air bags are arranged in sequence with a plurality of air cavities, and a partition layer 202 is obliquely disposed between two adjacent air cavities, and each air cavity constitutes the support area.

[0031] In one embodiment, the airbag assembly consists of a single flexible airbag body made of thermoplastic polyurethane (TPU) film formed by high-frequency compression. Multiple independent air chambers are arranged along the length of the airbag body, each forming an independent support area. Adjacent air chambers are separated by flexible partitions 202 that are inclined in the same direction, with all partitions 202 maintaining the same inclination.

[0032] It is equipped with five independent air chambers, which are arranged in sequence along a predetermined direction as air chamber A101, air chamber B102, air chamber C103, air chamber D104, and air chamber E105;

[0033] When air chamber B102 is inflated, its non-overlapping area at least partially fills the fault in the overlapping area when air chamber A101 is inflated.

[0034] When air chamber C103 is inflated, its non-overlapping area at least partially fills the fault in the overlapping area when air chamber B102 is inflated;

[0035] When air chamber D104 is inflated, its non-overlapping area at least partially fills the fault in the overlapping area when air chamber C103 is inflated;

[0036] When air chamber E105 is inflated, its non-overlapping area at least partially fills the fault in the overlapping area when air chamber D104 is inflated.

[0037] In this embodiment, as Figure 3 As shown, the partitions 202 between each pair of adjacent air chambers are arranged obliquely in the same direction. The oblique partitions 202 cause the adjacent air chambers to partially overlap along the arrangement direction after inflation.

[0038] In this embodiment, along the arrangement direction, the Nth support region at least partially fills the fault when the N-1th support region is inflated.

[0039] Adjacent airbags are physically separated by an oblique partition 202, which is integrally formed with the airbag body through high-frequency pressing, creating a non-perpendicular oblique separation interface. The design of the oblique partition 202 results in partially overlapping and non-overlapping areas after adjacent airbags are inflated. The overlapping part forms a stable layered structure, while the non-overlapping area becomes the key space for subsequent airbag filling.

[0040] When air chamber A101 is inflated alone, its top surface is restricted by the oblique partition 202, forming a stepped fault on its right edge. This fault needs to be filled by the uncovered area of ​​the adjacent air chamber B102: when air chamber B102 is inflated, its unoverlapping area on the left expands upward, precisely embedding into the fault space of air chamber A101. At the same time, a new fault is generated on the right side of air chamber B102 itself, which is subsequently filled by air chamber C103. This process forms a cascading filling effect, eliminating gaps in the support surface 40. When all air chambers are inflated, the bottom of the upper air chamber naturally covers the edge of the lower air chamber, and the deformation of the flexible material allows the support surfaces 40 of adjacent support areas to connect seamlessly, forming a smooth supporting surface.

[0041] In this embodiment, several of the support areas are arranged along a straight line or a curve.

[0042] In this embodiment, after the several support areas are inflated, the support surfaces 40 of the support areas are in the same plane or form a smooth curved surface.

[0043] Each partition 202 is an inclined plane, the inclination angle of which causes adjacent air chambers to misalign in a stepped manner during inflation. For example, the partition 202 between air chamber A101 and air chamber B102 causes the edge of A to cover the top of air chamber B102. The partition 202 between air chamber B102 and air chamber C103 causes air chamber C103 to cover the upper right side of air chamber B102, and so on, forming a continuous covering chain.

[0044] Furthermore, each of the aforementioned support areas is provided with an inflation / deflation port. Each air chamber is equipped with a dedicated inflation port 30, which is connected to an external air pump via an independent air path. The inflation sequence is triggered by the controller in the order of air chamber A101, air chamber B102, air chamber C103, air chamber D104, and air chamber E105, ensuring that the subsequent air chamber begins to expand after the preceding air chamber has formed a stable structure.

[0045] The air chamber A101 is inflated to a predetermined pressure, and a local support surface 40 is formed on its top surface. However, a downwardly tilted fault region is formed on the right side due to the constraint of the inclined partition 202.

[0046] Inflation of air chamber B102: The uncovered area on the left side is pushed upwards, completely filling the fault in air chamber A101, while a new fault is formed on its right side.

[0047] Inflate air chamber C103: Fill the fault in air chamber B102 and transfer the fault to the subsequent air chambers on the right side, activating them sequentially according to the same mechanism, until air chamber E105 fills the fault in air chamber D104.

[0048] After all air chambers are inflated, the covered areas of the preceding air chambers and the filled areas of the subsequent air chambers interlock to form a continuous plane or a smooth arc surface with no height difference on the top of the air chamber body.

[0049] Furthermore, the air cavity is made of a flexible material, including thermoplastic polyurethane or polyvinyl chloride.

[0050] In other embodiments, when the air cavities are arranged along the curve, the tilt angle of the oblique partition 202 is dynamically adjusted with the curvature of the curve, so that the expansion direction of each air cavity is always perpendicular to the tangent of the target surface, and finally a seamless surface is synthesized.

[0051] The present invention discloses an air chamber component for a massage leg bandage, the manufacturing method of which is as follows:

[0052] like Figure 4 As shown, it is made of three materials: TPU-A, TPU-B, and TPU-C. TPU-A and TPU-B are high-frequency laminated to form the upper half of air cavity A101, and TPU-C and TPU-B are high-frequency laminated to form the lower half of air cavity A101. Finally, the upper and lower parts are high-frequency laminated together to form air cavity A101. Similarly, TPU-A and TPU-B are high-frequency laminated to form the upper half of air cavity B102, and TPU-C and TPU-B are high-frequency laminated to form the lower half of air cavity B102. Finally, the upper and lower parts are high-frequency laminated together to form air cavity B102. Finally, TPU-A and TPU-B are high-frequency laminated to form the upper half of air cavity C103. In the first half, TPU-C and TPU-B are high-frequency pressed together to form the lower half of air cavity C103. Finally, the upper and lower parts are high-frequency pressed together to form air cavity C103. In the second half, TPU-A and TPU-B are high-frequency pressed together to form the upper half of air cavity D104. TPU-C and TPU-B are high-frequency pressed together to form the lower half of air cavity D104. Finally, the upper and lower parts are high-frequency pressed together to form air cavity D104. In the third half, TPU-A and TPU-B are high-frequency pressed together to form the upper half of air cavity E105. TPU-C and TPU-B are high-frequency pressed together to form the lower half of air cavity E105. Finally, the upper and lower parts are high-frequency pressed together to form air cavity E105.
