Description

Technical Field

[0001] The utility model relates to the field of swimming auxiliary equipment, in particular to buoyancy auxiliary equipment. Background Art

[0002] Swimming, as a sport that combines leisure and exercise, has gradually gained popularity. Beginners (especially children) often need to wear buoyancy aids when learning to swim. Buoyancy aids provide buoyancy to the wearer (i.e., beginners, hereinafter referred to as the wearer for ease of description) to assist with swimming practice.

[0003] Buoyancy aids primarily consist of a chest support that fits over the wearer's chest and arm loops that fit over the wearer's arms, providing buoyancy to the wearer's upper body. However, current buoyancy aids are limited in their use cases and are not suitable for further development as swimming training progresses. Utility Model Content

[0004] The present invention aims to address the limited application scenarios of current buoyancy aids, which are not suitable for various stages of swimming learning. The present invention provides a buoyancy aid with an arm loop liner that can be removed from the buoyancy aid and worn separately on the wearer's arm, allowing the wearer to use it at different stages of swimming learning.

[0005] In order to solve the above technical problems, the embodiment of the present utility model discloses a buoyancy assist device, comprising:

[0006] chest support;

[0007] The arm ring is connected to the chest support and includes:

[0008] Arm loop jacket, including:

[0009] external film;

[0010] An inner sheet connected to the outer sheet and defining an inner container accommodating space with the outer sheet;

[0011] a side panel connected to the inner panel and the outer panel, and defining an opening with the inner panel or the outer panel, wherein the inner container accommodation space communicates with the outside through the opening;

[0012] The arm ring liner is arranged in the liner accommodating space, including:

[0013] a first liner connection portion, provided at a first end of the arm loop liner;

[0014] a second liner connecting portion, disposed at the second end of the arm loop liner and detachably connected to the first liner connecting portion;

[0015] The arm loop airbag includes an arm loop air valve, which is arranged between the first inner liner connecting part and the second inner liner connecting part.

[0016] Using the above technical solution, an arm loop is provided on each side of the chest support. Each arm loop includes an arm loop outer shell and an arm loop inner shell. A first and a second inner shell connector are provided at each end of the arm loop inner shell, and an arm loop airbag is provided in the portion of the arm loop inner shell located between the first and second inner shell connectors. The first and second inner shell connectors are detachably connected to define a liner gap within the arm loop inner shell. The liner gap allows the wearer's arm to pass through, allowing the arm loop inner shell to be placed over the wearer's arm, and the arm loop airbag provides buoyancy to the wearer's arm. An opening is also provided in the arm loop outer shell for the arm loop inner shell to pass through. When the arm loop airbag within the arm loop inner shell is in a non-inflated state, the arm loop inner shell is small in size, allowing it to be easily inserted into the liner storage space of the arm loop outer shell through the opening, or removed from the liner storage space of the arm loop outer shell through the opening for separate wearing on the wearer's arm.

[0017] In other words, the present invention provides a buoyancy aid device with a detachable armband liner that can be used independently. Thus, when the wearer is just starting to learn to swim, they can wear the buoyancy aid device (i.e., including a chest support and armbands) to achieve a stronger buoyancy aid effect. When the wearer reaches the next stage of learning (the next stage is the stage where the chest support is no longer needed), the armband liner located inside the armband outer shell can be removed and the armband liner can be directly placed on the arm to provide buoyancy assistance to the wearer. In other words, the buoyancy aid device provided in the embodiment of the present application can be used by the wearer at multiple stages in the process of learning to swim, increasing the application scenarios of the buoyancy aid device and meeting the needs of different swimming learning stages.

[0018] According to a specific embodiment of the present invention, the arm loop liner includes a plurality of arm loop airbags, and the plurality of arm loop airbags are distributed along the length direction of the arm loop liner;

[0020] According to a specific embodiment of the present invention, the first liner connecting portion includes a first hook and loop fastener;

[0021] The second liner connecting portion includes a second Velcro, and the second Velcro is detachably connected to the first Velcro.

[0022] By adopting the above technical solution, the first liner connecting portion and the second liner connecting portion are configured as Velcro, which has a simple and effective structure and low cost.

[0023] According to a specific embodiment of the present invention, the arm ring further includes:

[0024] a connecting piece, one side of the connecting piece being connected to one side of the arm loop coat, and the other side of the connecting piece being connected to the other side of the arm loop coat;

[0025] Wherein, the inner sheet and the connecting sheet define an outer shell gap.

[0026] According to a specific embodiment of the present invention, an elastic sheet is further included, and the elastic sheet includes:

[0027] a first end connected to the outer sheet;

[0028] The second end is provided with a first elastic connection portion, and the first elastic connection portion extends along the length direction of the elastic sheet;

[0029] The outer sheet also includes:

[0030] A second elastic connection portion is detachably connected to the first elastic connection portion, and the connecting piece is located between the first end of the elastic piece and the second end of the elastic piece.

[0031] Using the above technical solution, a second elastic connection portion and an elastic sheet are provided on the outer panel of the armband jacket, and a first elastic connection portion is provided at the end of the elastic sheet away from the armband. The first elastic connection portion and the second elastic connection portion are detachably connected. When the wearer needs to adjust the tightness of the armband, the first elastic connection portion can be separated from the second elastic connection portion and the elastic sheet can be pulled to move the first elastic connection portion circumferentially relative to the second elastic connection portion to adjust the tightness of the armband. After the adjustment is completed, the wearer only needs to maintain the tightness and connect the first elastic connection portion to the second elastic connection portion, effectively improving the versatility of the armband.

[0032] According to a specific embodiment of the present invention, the first elastic connection portion includes a third hook and loop fastener;

[0033] The second elastic connection portion includes a fourth hook and loop fastener, and the third hook and loop fastener are detachably connected to the fourth hook and loop fastener.

[0034] According to a specific embodiment of the present invention, the chest support further includes:

[0035] Chest support body;

[0036] A first connecting portion is provided on one side of the chest support body;

[0037] a second connecting portion, provided on the other side of the chest support body and detachably connected to the first connecting portion;

[0038] A wearing space is defined by the chest support body, the first connecting part and the second connecting part.

[0039] By adopting the above technical solution, a wearing space is defined by the chest support body, the first connecting part and the second connecting part, so that the wearer can wear the buoyancy assistance equipment to provide buoyancy assistance to the wearer.

[0040] According to a specific embodiment of the present invention, the chest support body further includes:

[0044] According to a specific embodiment of the present invention, the chest support further includes:

[0045] The buoyancy sheet is arranged in the chest support accommodating space and is located between the chest support airbag and the wearing space.

[0046] By adopting the above technical solution, a buoyancy plate is set between the wearing space and the chest support airbag, which can prevent the chest support airbag from directly pressing against the wearer's chest, effectively improving the wearer's comfort when wearing the chest support. When the airbag leaks, it can also provide a certain amount of buoyancy to avoid the complete loss of buoyancy and the danger.

[0047] According to a specific embodiment of the present invention, the buoyancy sheet is made of EPE.

[0048] EPE (Expandable Polyethylene) has the advantages of light weight and strong toughness. Adopting the above technical solution and using EPE as the material of the buoyancy sheet can improve the wearer's comfort while avoiding affecting the performance of the buoyancy assist equipment.

[0054] A connecting end connected to the chest support body;

[0055] Wherein, the maximum length of the hanging strap is not less than the distance from the connecting end to the air valve port.

[0056] By adopting the above technical solution, a hanging strap is provided on the chest support main body. When the buoyancy assist device is not in use, the air valve can be hung on it to limit the air valve to prevent the air valve from shifting to the inside of the chest support when it is used next time, making it inconvenient to inflate; the hanging strap can also be hung on a hook or other storage place for easy storage; when the wearer wears the buoyancy assist device, the hanging strap can be hung on the chest support air valve to prevent the hanging strap from hooking foreign objects and causing danger.

[0057] According to a specific embodiment of the present invention, the chest support airbag includes:

[0058] A plurality of welding lines are distributed along the length direction of the chest support airbag;

[0059] Each of the plurality of welding lines extends along a width direction of the chest support airbag.

[0060] Using this technical solution, the chest support airbag is welded at multiple locations along its length, and the welding direction is along its width, forming multiple weld lines. These weld lines can limit the maximum expansion height of the chest support airbag when inflated, making the chest support airbag relatively flat after inflation, and thus making the chest support body relatively flat when worn, improving wearing comfort.

[0083] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0084] refer to Figure 1 and Figure 2 This embodiment provides a buoyancy aid device 10 for use by a wearer learning to swim, providing buoyancy and assisting the wearer in swimming practice. Specifically, the buoyancy aid device 10 includes a chest support 100 and two arm loops 200 . One arm loop 200 is connected to one side of the chest support 100 , and the other arm loop 200 is connected to the other side of the chest support 100 .

[0085] The chest support 100 includes a chest support body 110, a first connection portion 120, and a second connection portion 130. The chest support body 110 includes a first side 111 and a second side 112. The first connection portion 120 is provided on one side of the chest support body (i.e., the first side 111), and the second connection portion 130 is provided on the other side of the chest support body (i.e., the second side 112). The first connection portion 120 and the second connection portion 130 are detachably connected so that the chest support body 110, the first connection portion 120, and the second connection portion 130 define a wearing space 140 for the wearer to wear. Specifically, when the wearer wears the buoyancy aid 10, the wearing space 140 accommodates a portion of the wearer's upper body.

[0086] When the wearer wears the above-mentioned buoyancy assist device 10, the two arms are respectively extended into an arm loop 200, that is, each arm loop 200 is mounted on one arm of the wearer, and the chest support body 110 is located in front of the wearer's chest to provide buoyancy for the wearer.

[0087] The specific structure of the first connecting portion 120 and the second connecting portion 130 is not limited in the present embodiment, as long as the wearing space 140 can be formed for the wearer to wear. Figure 1 and Figure 2 In this embodiment, the first connecting portion 120 includes a first connecting strap 121 and a first buckle 122, and the second connecting portion 130 includes a second connecting strap 131 and a second buckle 132. Specifically, one end of the first connecting strap 121 is connected to the first side 111 of the chest support body, and the other end is connected to the first buckle 122. One end of the second connecting strap 131 is connected to the second side 112 of the chest support body, and the other end is connected to the second buckle 132. The first buckle 122 and the second buckle 132 are detachably connected, so that the chest support body 110, the first connecting strap 121 and the second connecting strap 131 define the above-mentioned wearing space 140. In other possible embodiments, the first connecting portion 120 and the second connecting portion 130 can also be Velcro.

[0088] In one possible embodiment, the first side 111 of the chest support body extends outward to form a right wing 113, and the second side 112 of the chest support body extends outward to form a left wing 114. The aforementioned first connecting strap 121 is connected to the right wing 113, and the second connecting strap 131 is connected to the left wing 114. When worn by the wearer, the left wing 114 covers the wearer's left underarm and supports the wearer's left arm to provide buoyancy. The right wing 113 covers the wearer's right underarm and supports the wearer's right arm to provide buoyancy.

[0089] Continue to refer Figure 1 and Figure 2 One of the two arm loops 200 is connected to the first side 111 of the chest support body, and the other arm loop 200 is connected to the second side 112 of the chest support body. Optionally, each arm loop 200 is connected to the chest support body 110 via an arm loop connecting belt 101.

[0090] In the embodiment of the present application, the arm loop connecting belt 101 is made of cloth, that is, the arm loop connecting belt 101 is a cloth strip. In other embodiments, the arm loop connecting belt 101 is made of other materials (for example, but not limited to, PVC, TPU, nylon, etc.).

[0091] The embodiment of the present application does not impose any specific restrictions on the connection method of the arm loop connecting strap 101 to the chest support body 110 and the arm loop 200. For example, in the embodiment of the present application, the arm loop connecting strap 101 is connected to the chest support body 110 and the arm loop 200 by sewing, but is not limited to this. In other possible embodiments, the arm loop connecting strap 101 can also be connected to the chest support body 110 and the arm loop 200 by welding or other methods.

[0092] refer to Figures 1 to 4 , the chest support body 110 also includes: a chest support wall 102, a chest support airbag 170, three buoyancy sheets 180 and a strap 190. The chest support wall 102 includes a first piece 150 and a second piece 160 that are connected to each other, and define a chest support accommodating space 1101. Optionally, the first piece 150 and the second piece 160 are connected by sewing. The chest support airbag 170 and the three buoyancy sheets 180 are arranged in the chest support accommodating space 1101, and the three buoyancy sheets 180 are located between the chest support airbag 170 and the wearing space 140. The chest support airbag 170 is used to provide buoyancy for the wearer, so as to provide buoyancy assistance when the wearer is learning to swim. In other embodiments, the chest support wall 102 may also be composed of a single piece or more than three pieces.

[0093] The embodiment of the present application does not impose any specific limitation on the connection method between the first piece 150 and the second piece 160. In other possible implementations, the first piece 150 and the second piece 160 may also be connected by welding or other methods.

[0094] For example, when a wearer wears the buoyancy aid device 10, the first sheet 150 rests against the wearer's chest, while the second sheet 160 lies away from the wearer's chest. The three buoyancy sheets 180 are positioned between the first sheet 150 and the chest support airbag 170 to prevent the chest support airbag 170 from directly pressing against the wearer's chest, effectively improving the comfort of the buoyancy aid device 10. Accordingly, the chest support airbag 170 is positioned between the buoyancy sheets 180 and the second sheet 160.

[0095] In some possible embodiments, the buoyancy sheet 180 is made of EPE (Expandable Polyethylene), which has advantages such as light weight and high toughness. However, the present invention is not limited thereto. In other possible embodiments, the buoyancy sheet 180 may be made of other materials, such as PVC (Polyvinyl chloride).

[0096] The embodiment of the present application does not limit the specific number of buoyancy sheets 180. In other possible implementations, the number of buoyancy sheets 180 can also be one, two, four, five, or other multiple sheets.

[0097] In some possible implementations, refer to FIG3 and combine Figure 1 and Figure 2 A chest support air valve 171 is provided on the side of the chest support air bag 170 facing the second piece 160, that is, the chest support air valve 171 is provided on the side of the chest support air bag 170 away from the wearing space 140. The chest support air valve 171 is configured to inflate or deflate the chest support air bag 170. The wearer can inflate the chest support air bag 170 through the chest support air valve 171 to expand the volume of the chest support air bag 170 and provide buoyancy for the wearer. Alternatively, the wearer can deflate the chest support air bag 170 through the chest support air valve 171 to reduce the volume of the chest support air bag 170 so as to facilitate the storage of the buoyancy aid equipment 10.

[0098] Accordingly, continue to refer to Figure 3 and combine Figure 1 and Figure 2 The second piece 160 is provided with an air valve port 161, through which the chest support air valve 171 passes to expose the chest support air valve 171, so that the wearer can inflate or deflate the chest support airbag 170 through the chest support air valve 171. For example, in some other possible embodiments, the chest support air valve 171 is located in the air valve port 161 (not shown), so that the wearer can inflate or deflate the chest support airbag 170 through the chest support air valve 171.

[0099] In other possible embodiments, when the wearer wears the buoyancy aid device 10, the second sheet 160 is against the wearer's chest, and the first sheet 150 is away from the wearer's chest. The three buoyancy sheets 180 are located between the second sheet 160 and the chest support airbag 170 to prevent the chest support airbag 170 from directly squeezing the wearer's chest, effectively improving the comfort of the buoyancy aid device 10. Accordingly, the chest support airbag 170 is located between the buoyancy sheets 180 and the first sheet 150. A chest support air valve 171 is provided on the side of the chest support airbag 170 facing the first sheet 150. That is, the chest support air valve 171 is provided on the side of the chest support airbag 170 away from the wearing space 140. An air valve port 161 is provided on the first sheet 150. The air valve port 161 allows the chest support air valve 171 to pass through, exposing the chest support air valve 171 and facilitating the wearer to inflate or deflate the chest support airbag 170 through the chest support air valve 171.

[0100] Exemplarily, the air valve opening 161 is circular, but not limited thereto. In other possible implementations, it may be rectangular, elliptical, or other shapes, as long as the chest support air valve 171 can pass through.

[0101] In some possible implementations, reference Figure 3b and combined Figure 2The chest support airbag 170 includes two welding lines 172. Exemplarily, the two welding lines 172 are spaced apart along the length direction U of the chest support airbag 170, and each of the two welding lines 172 extends along the width direction V of the chest support airbag 170. The welding lines 172 are formed by welding the side of the chest support airbag 172 facing the first sheet 150 and the side facing the second sheet 160.

[0102] It should be noted that, along the width direction V of the chest support airbag 170, there is a gap between each welding line 172 and the top of the chest support airbag 170, and there is a gap between each welding line 172 and the bottom of the chest support airbag 170, so that the air chambers on both sides of each welding line 172 (not shown in the figure) are conductive.

[0103] This arrangement enables the welding line 172 to limit the maximum expansion height of the chest support airbag 170 when inflated, so that the chest support airbag 170 is relatively flat after inflation, and further makes the chest support body 110 relatively flat when worn, thereby improving wearing comfort.

[0104] The number of welding lines 172 is not specifically limited in this embodiment and can be adjusted according to the actual length of the chest support airbag 170. For example, in other possible embodiments, the number of welding lines 172 of the chest support airbag 170 can be three, four, five, or more.

[0105] In some possible implementations, continue to refer to Figure 3b and combined Figure 2 An airbag connection portion 173 is provided at the top of the chest support airbag 170 along the width direction V of the chest support airbag 170. The airbag connection portion 173 is connected to the chest support wall 102 by sewing, so that the chest support airbag 170 and the chest support wall 102 have a relatively stable position relationship, preventing the chest support airbag 170 from moving within the chest support accommodating space 1101, and further improving wearing comfort.

[0106] The embodiment of the present application does not impose any specific restrictions on the connection method between the airbag connecting part 173 and the chest support wall 102. Optionally, the airbag connecting part 173 and the chest support wall 102 can also be connected by welding, gluing, etc.

[0107] In some possible implementations, reference Figure 1 and Figure 2In conjunction with Figure 3 , one end of the sling 190 is a connecting end 191, which is connected to the first piece 150 by sewing. The maximum length of the sling 190 is no less than the distance from the air valve opening 161 to the connecting end 191, so that the sling 190 can be hooked onto the air valve 171. When the sling 190 is made of a non-elastic material and is straightened, the distance from the connecting end 191 to the other end of the sling 190 is the maximum length of the sling 190. When the sling 190 is made of an elastic material and is stretched to its maximum length, the distance from the connecting end 191 to the other end of the sling 190 is the maximum length of the sling 190.

[0108] Specifically, when the wearer wears the buoyancy aid device 10, the other end of the strap 190 (i.e., the end of the strap 190 away from the connection end 191) can be hung on the chest support valve 171, which can effectively prevent the strap 190 from hooking foreign objects during swimming and causing danger to the wearer; when the wearer is not wearing the buoyancy aid device 10, the other end of the strap 190 can be hung on a hook or other storage place to facilitate the storage of the buoyancy aid device 10.

[0109] In other possible implementations, one end of the hanging strap 190 may also be connected to the second piece 160 , or the connection between the first piece 150 and the second piece 160 .

[0110] refer to Figure 5 and combined Figure 1 and Figure 2 In the embodiment of the present application, each arm loop 200 of the buoyancy assist device 10 includes an arm loop outer shell 210 and an arm loop liner 220. The arm loop outer shell 210 is connected to the chest support 100, and the arm loop liner 220 is detachably arranged inside the arm loop outer shell 210. Moreover, the arm loop liner 220 can be separately mounted on the wearer's arm to provide buoyancy to the wearer.

[0111] Thus, when a wearer is just learning to swim, they can wear the buoyancy aid device 10 (i.e., comprising the chest support 100 and the arm loops 200) to achieve a stronger buoyancy aid effect. When the wearer reaches the next stage of learning (the next stage is the stage where the chest support 100 is no longer needed), the arm loop liner 220 located inside the arm loop outer shell 210 can be removed and the arm loop liner 220 can be directly placed on the arm. In other words, the buoyancy aid device 10 provided in this embodiment of the application can be used by the wearer at multiple stages of the swimming learning process, increasing the application scenarios of the buoyancy aid device 10 and meeting the needs of different swimming learning stages.

[0112] In addition, the arm loop liner 220 can be reinstalled into the arm loop outer shell 210 so that the buoyancy aid device 10 can be reused to avoid waste.

[0113] The specific structure of the arm ring 200 will be described in detail below with reference to the accompanying drawings.

[0114] In one possible implementation, reference Figure 5 and combined Figure 6 The armband 200 includes an armband outer shell 210 and an armband liner 220. The armband liner 220 includes an armband airbag 224, which is used to provide buoyancy to the wearer's arms. The armband liner 220 is detachably mounted inside the armband outer shell 210. When the armband liner 220 is detached from the armband outer shell 210, the armband liner 220 can be worn by the wearer alone to provide buoyancy to the wearer's arms.

[0115] refer to Figure 6 and combined Figure 5 In one possible embodiment, an inner liner accommodating space 2101 is provided inside the arm ring jacket 210, and the inner liner accommodating space 2101 is used to accommodate the arm ring liner 220, so that the arm ring 200 can provide buoyancy to the wearer's arm.

[0116] Specifically, an opening 211 is provided on the outer surface of the arm ring jacket 210, and the opening 211 is connected to the inner liner accommodating space 2101. The opening 211 is for the arm ring airbag 224 of the above-mentioned arm ring inner liner 220 to pass through in a non-inflated state, so as to take out the arm ring jacket 210 from the inner liner accommodating space 2101 for separate use, or put it into the inner liner accommodating space 2101 from the outside.

[0117] Furthermore, the arm loop outer shell 210 is formed into a generally annular structure to define an outer shell gap 212 for the wearer's arms to pass through, so that the arm loop 200 provides buoyancy to the wearer's arms.

[0118] like Figure 9 As shown, when the arm loop airbag 224 of the arm loop liner 220 is in a non-inflated state, the arm loop liner 220 is in a sheet-like shape (small in volume), and the arm loop liner 220 can pass through the opening 211 to enter the liner storage space 2101 or leave the liner storage space 2101 for individual use by the wearer. However, this is not limiting. In other possible embodiments, when the arm loop airbag 224 of the arm loop liner 220 is in a non-inflated state, the arm loop liner is not in a sheet-like shape, as long as the volume of the arm loop liner 220 allows the arm loop liner 220 to pass through the opening 211 to enter or leave the liner storage space 2101.

[0119] Specifically, when a wearer is just learning to swim, they can wear the buoyancy aid 10, with the arm loop liner 220 located in the liner storage space 2101 and the arm loop airbags 224 of the arm loop liner 220 inflated. As the wearer's swimming proficiency improves and they reach the next stage (a stage where they no longer need to use the chest support 100), they can first switch the arm loop airbags 224 of the arm loop liner 220 to a non-inflated state, so that the arm loop liner 220 is in sheet form, and then remove the sheet-shaped arm loop liner 220 from the liner storage space 2101 of the arm loop jacket 210 through the opening 211 (i.e., the arm loop liner 220 passes through the opening 211 to leave the liner storage space 2101). Next, the arm ring airbag 224 of the arm ring liner 220 is inflated to put it in an inflated state. At this time, there is no need to wear the chest support 100. The arm ring liner 220 can be worn alone on the arm to carry out the next stage of swimming learning.

[0120] After the next stage (the stage where the chest support 100 is not required) of learning is completed, the arm loop airbags 224 of the arm loop liner 220 can be deflated, switching the arm loop airbags 224 from an inflated state to a non-inflated state, so that the arm loop liner 220 is in a sheet-like shape. The sheet-like arm loop liner 220 is then placed into the liner accommodation space 2101 of the arm loop jacket 210 through the opening 211 (i.e., the arm loop liner 220 passes through the opening 211 to enter the liner accommodation space 2101). The arm loop airbags 224 of the arm loop liner 220 are then inflated, switching the arm loop airbags 224 from a non-inflated state to an inflated state, so that the arm loop liner 220 is confined within the liner accommodation space 2101. In this way, the buoyancy aid 10 can be used by the wearer to subsequently relearn the previous stage (the stage where both the chest support 100 and the arm loops 200 are required to be worn simultaneously), or by other swimming beginners for reuse to avoid waste.

[0121] Continue to refer Figure 6 and combined Figure 5 In one possible embodiment, the armband jacket 210 includes an outer panel 213, an inner panel 214, two side panels 215, and a connecting panel 216. The inner panel 214 is connected to the outer panel 213 to define the aforementioned liner storage space 2101. Each of the two side panels 215 defines an opening 211 with the outer panel 213. A portion of each of the two side panels 215 overlaps a portion of the outer panel 213 and is located inside the outer panel 213.

[0122] Specifically, refer to Figure 7 and combined Figure 5 and Figure 6 , Figure 7The arm loop 200 is shown in a schematic diagram of an exploded structure, wherein the outer sheet 213, the inner sheet 214 and the side sheet 215 are all in a flattened state, and Figure 7 In the figure, the length directions of the outer panel 213, the inner panel 214 and the side panel 215 are the same as the length direction X of the arm ring liner 220, and the width directions of the outer panel 213, the inner panel 214 and the side panel 215 are the same, which are the width direction Y, and the width direction Y is perpendicular to the length direction X.

[0123] It should be noted that the reference Figure 7 and Figure 8 When the arm loop liner 220 is flattened (the first liner connecting portion 222 is not connected to the second liner connecting portion 223), the arm loop airbags 224 are distributed along the straight line direction X (such as Figure 9 As the arm loop liner 220 defines the liner gap 221 (ie, the first liner connection portion 222 is connected to the second liner connection portion 223), the arm loop airbags 224 are distributed along the circumferential direction R (as shown). Figure 10 As shown, the circumferential direction R surrounds the inner tank gap 221).

[0124] For example, continue to refer to Figure 7 and combined Figure 5 and Figure 6 The two side panels 215 are connected to the outer panel 213 and the inner panel 214 on both sides along the length direction X, with one side ( Figure 7 The left side in the figure is used as an example to illustrate the connection relationship between the outer piece 213, the inner piece 214 and the side piece 215.

[0125] refer to Figure 7 and combined Figure 5 and Figure 6 For example, the outer sheet 213 includes a side edge 213a, a side edge 213b and a side edge 213c. Figure 7 Taking the middle perspective as an example, side edge 213c is the left side of outer sheet 213. Side edge 213a and side edge 213b are located on both sides of outer sheet 213 along width direction Y, and side edge 213a and side edge 213b are located between dotted line a (dotted line a is for illustration only and is parallel to width direction Y) and side edge 213c along length direction X.

[0126] Exemplarily, the inner sheet 214 includes a side edge 214a, a side edge 214b, and a side edge 214c. Figure 7 Taking the middle perspective as an example, side edge 214c is the left side of inner panel 214. Side edge 214a and side edge 214b are located on both sides of inner panel 214 along width direction Y, and side edge 214a and side edge 214b are located between dotted line b (dotted line b is for illustration only and is parallel to width direction Y) and side edge 214c along length direction X.

[0127] Exemplarily, the side panel 215 includes a side edge 215a, a side edge 215b and a side edge 215c. Figure 7 Taking the middle perspective as an example, the side edge 215c is the left side of the side panel 215. The side edge 215a and the side edge 215b are located on both sides of the side panel 215 along the width direction Y.

[0128] Specifically, the side edge 213a of the outer sheet 213 is connected to the side edge 214a of the inner sheet 214 and the side edge 215a of the side sheet 215, the side edge 213b of the outer sheet 213 is connected to the side edge 214b of the inner sheet 214 and the side edge 215b of the side sheet 215, and the side edge 215c of the side sheet 215 is connected to the side edge 214c of the inner sheet 214. In other words, the side edge 213c of the outer sheet 213 is not connected to the side sheet 215 and the inner sheet 214, and the side edge 213c of the outer sheet 213 and the side sheet 215 form the aforementioned opening 211. When the arm loop airbag 224 of the arm loop liner 220 is in a non-inflated state (at this time, the arm loop liner 220 is in a sheet-like state), the arm loop liner 220 can be removed from the opening 211 for separate use, or placed into the liner accommodating space 2101 through the opening 211.

[0129] refer to Figure 8 Combined with Figure 5 When the arm loop liner 220 is located in the liner accommodating space 2101 , the first end 2201 and the second end 2202 of the arm loop liner 220 are respectively folded inward and closely attached to the arm loop liner 220 .

[0130] For example, refer to Figure 5 The side panels 215 further include overlapping portions 2151 that overlap with a portion of the outer panel 213 and are located on the inner side of the outer panel 213. When the arm loop airbags 224 of the arm loop liner 220 are inflated, the arm loop airbags 224 of the arm loop liner 220 abut against the overlapping portions 2151 of the side panels 215, so that the overlapping portions 2151 are closely attached to the inner side of the outer panel 213, thereby confining the arm loop liner 220 within the liner accommodating space 2101. That is, the arm loop airbags 224 of the arm loop liner 220 cannot be removed from the arm loop jacket 210 when inflated.

[0131] In one possible implementation, continue with reference to Figure 7 and combined Figure 5 and Figure 6The connecting piece 216 is connected to the side edge 214c of the inner sheet 214 along one side of the longitudinal direction X, and is connected to the side edge 214d of the inner sheet 214 along the other side of the longitudinal direction X. The side edge 214d and the side edge 214c are respectively located on both sides of the inner sheet 214 along the longitudinal direction X. The connecting piece 216 and the inner sheet 214 define the aforementioned outer sleeve gap 212, which is for the wearer's arm to pass through, so that the armband 200 is placed on the wearer's arm.

[0132] In another possible implementation, continue to refer to Figure 7 The connecting piece 216 is connected to the side 214c or side 214d of the inner piece 214 on one side along the length direction X, and is connected to the side piece 215 on the other side, so that the inner piece 214, a part of a side piece 215 and the connecting piece 216 define the aforementioned coat gap 212, and the coat gap 212 is for the wearer's arm to pass through, so that the arm loop 200 is placed on the wearer's arm.

[0133] In other possible implementations, continue to refer to Figure 7 Alternatively, the connecting piece 216 may be connected to one of the two side pieces 215 on both sides along the length direction X, that is, the connecting piece 216, a portion of each of the two side pieces 215 and the inner piece 214 define the aforementioned coat gap 212, and the coat gap 212 is for the wearer's arm to pass through so that the arm loop 200 is placed on the wearer's arm.

[0134] The number of the connecting pieces 216 is not specifically limited in this embodiment of the application. For example, Figure 7 In the embodiment of the present application, the number of connecting pieces 216 is two to enhance the structural strength of the armband jacket 210 while also improving the comfort of the wearer. However, this is not limiting. In other possible embodiments, the number of connecting pieces 216 may be one, three, four, five, or more.

[0135] The embodiment of the present application does not limit the connection method between the outer sheet 213, the inner sheet 214, the side sheet 215 and the connecting sheet 216. For example, in the embodiment of the present application, the outer sheet 213, the inner sheet 214, the side sheet 215 and the connecting sheet 216 are connected by sewing, but are not limited to this. In other possible embodiments, the outer sheet 213, the inner sheet 214, the side sheet 215 and the connecting sheet 216 can also be connected by welding or other methods. For example, in other possible embodiments, the outer sheet 213, the inner sheet 214, the side sheet 215 and the connecting sheet 216 can also be integrally formed.

[0136] It should be noted that the number of openings 211 of the arm loop jacket 210 is not specifically limited in the present embodiment. For example, Figure 5 In the embodiment of the present application, the number of openings 211 is two, but it is not limited thereto. In other possible implementations, the number of openings 211 may also be one (not shown). Figure 7 For example, when the number of openings 211 is one, along the length direction X, there is no side panel 215 on the right side of the outer panel 213 (it can also be the left side, the right side is taken as an example here), and the side edge 213d of the outer panel 213 (along the length direction X, the side edge 213d and the side edge 213c are respectively located on both sides of the outer panel 213) is directly connected to the inner panel 214d.

[0137] refer to Figure 6 and combined Figure 7 The arm ring 200 also includes an elastic structure, which is used to adjust the tightness of the arm ring 200 to adapt to the wearer's arm, thereby improving the versatility of the arm ring 200. Specifically, the elastic structure includes: an elastic sheet 217, a first elastic connection portion 218 and a second elastic connection portion 219. The elastic sheet includes: a first end 2171 and a second end 2172. The first end 2171 of the elastic sheet 217 is connected to the outer sheet 213. The first elastic connection portion 218 is provided at the second end 2172 of the elastic sheet 217, and the first elastic connection portion 218 is arranged along the length direction X (such as Figure 7 As shown, the length direction of the elastic sheet 217 is the same as the length direction of the outer sheet 213).

[0138] Exemplarily, the second elastic connection portion 219 is provided on the outer plate 213, and along the circumferential direction R of the arm ring 200 (the circumferential direction R surrounds the jacket gap 212), the connecting piece 216 is located between the first end 2171 and the second end 2172 of the elastic piece 217, and the first elastic connection portion 218 can be detachably connected to the second elastic connection portion 219. When the first elastic connection portion 218 is connected to the second elastic connection portion 219, the extension direction of the first elastic connection portion 218 is the same as the extension direction of the second elastic connection portion 219.

[0139] The specific types of the first elastic connection portion 218 and the second elastic connection portion 219 are not particularly limited in this embodiment of the present application, as long as the first elastic connection portion 218 can be detachably connected to the second elastic connection portion 219 to adjust the tightness of the armband 200. Optionally, the first elastic connection portion 218 includes a third velcro 2181, and the second elastic connection portion 219 includes a fourth velcro 2191, and the third velcro 2181 and the fourth velcro 2191 are detachably connected.

[0140] When the wearer needs to adjust the tightness of the arm ring 200, the third Velcro 2181 can be separated from the fourth Velcro 2191, and the elastic sheet 217 can be pulled to move the third Velcro 2181 relative to the fourth Velcro 2191 along the circumferential direction R to adjust the tightness of the arm ring 200. After the adjustment is completed, it is only necessary to maintain the tightness and connect the third Velcro 2181 to the fourth Velcro 2191.

[0141] In one possible implementation, reference Figure 9 and Figure 10 and combined Figure 8 The arm loop liner 220 includes: a first liner connecting portion 222 , a second liner connecting portion 223 and two arm loop airbags 224 .

[0142] refer to Figure 10 and combined Figure 9 Specifically, the arm loop liner 220 has a first end 2201 and a second end 2202. A first liner connection portion 222 is provided at the first end 2201 of the arm loop liner, and a second liner connection portion 223 is provided at the second end 2202 of the arm loop liner. Furthermore, along the length direction X of the arm loop liner 220, two arm loop airbags 224 are located between the first liner connection portion 222 and the second liner connection portion 223. The arm loop airbags 224 are used to provide buoyancy to the wearer's arms, providing buoyancy assistance when the wearer is learning to swim. The second liner connection portion 223 is detachably connected to the first liner connection portion 222, so that the arm loop liner 220 defines an liner gap 221. The liner gap 221 allows the wearer's arm to pass through, allowing the arm loop liner 220 to be worn directly on the wearer's arm.

[0143] In some possible embodiments, the first liner connection portion 222 includes a first velcro 226, and the second liner connection portion 223 includes a second velcro 227. The second velcro 227 and the first velcro 226 are respectively located on opposite sides of the arm loop liner 220, so that the arm loop liner 220 defines an inner liner gap 221, and the first velcro 226 is detachably connected to the second velcro 227. However, the present invention is not limited thereto. In other possible embodiments, the first liner connection portion 222 and the second liner connection portion 223 may be connected by a snap fastener or other connection method, as long as the second liner connection portion 223 can be detachably connected to the first liner connection portion 222, so that the arm loop liner 220 defines an inner liner gap 221.

[0144] For example, refer to Figure 9 The two arm loop airbags 224 are spaced apart along the length direction X of the arm loop liner 220 so that the arm loop liner 220 can define an inner liner gap 221 , and the portion between the two arm loop airbags 224 is a connecting portion 228 .

[0145] For example, refer to Figures 8 to 10 The arm loop airbags 224 have inflated and deflated states. Each arm loop airbag 224 is provided with an arm loop air valve 225 on its outer surface. The arm loop air valve 225 is used to inflate the arm loop airbag 224 to switch from the deflated state to the inflated state, or to deflate the arm loop airbag 224 to switch from the deflated state to the inflated state. When the arm loop airbags 224 are in the deflated state, the arm loop liner 220 is in a sheet-like shape, making it easy to remove from or insert into the liner storage space 2101 of the arm loop outer garment 210. When the arm loop airbags 224 are in the inflated state, the arm loop liner 220 expands, confining the arm loop liner 220 within the liner storage space 2101 of the arm loop outer garment 210, thereby providing buoyancy to the wearer's arms.

[0146] For example, refer to Figure 9 The two arm loop airbags 224 are located on the same side of the arm loop liner 220 , but the present invention is not limited thereto. In other possible implementations, the two arm loop airbags 224 can also be located on opposite sides of the arm loop liner 220 .

[0147] The present embodiment does not specifically limit the number of arm loop airbags 224 in the arm loop liner 220. For example, in other possible embodiments, the number of arm loop airbags 224 can be one, three, four, five, or more. When there are multiple arm loop airbags 224, each adjacent pair of arm loop airbags 224 is spaced apart along the length direction X of the arm loop liner 220, so that the arm loop liner 220 defines an inner liner space 221. The number of arm loop air valves 225 corresponds to the number of arm loop airbags 224.

[0148] In some possible implementations, reference Figure 11 and combined Figure 9 The arm loop liner 220 includes a bottom sheet 2203 and an upper sheet 2204. The upper sheet 2204 includes two airbag portions 2204a and three non-airbag portions 2204b. The non-airbag portions 2204b are connected to the bottom sheet 2203 by welding, so that the airbag portions 2204a and the bottom sheet 2203 form the arm loop airbag 224.

[0149] In some other possible implementations, reference Figure 12 and combined Figure 9 The arm loop liner 220 includes a bottom film 2203 and two airbag sheets 2205 , and both ends of each airbag sheet 2205 are connected to the bottom film 2203 by welding to form an arm loop airbag 224 .

[0150] In summary, the buoyancy aid device 10 provided in the embodiment of the present application includes a chest support 100 and arm loops 200, each of which provides buoyancy to the wearer to ensure the wearer's safety while learning to swim. When the wearer reaches the next stage of learning (a stage where the chest support 100 is no longer needed), the arm loop liner 220 within the arm loop 200 can be removed and worn separately on the wearer's arm to provide buoyancy to the wearer's arm while learning to swim. This avoids the wearer having to purchase auxiliary equipment multiple times at different stages, saving the wearer the cost of learning to swim.

[0151] Thus far, this application has satisfactorily described the structures of the arm loop liner, arm loop, and buoyancy aid. These embodiments expand the use scenarios of the buoyancy aid and are applicable to multiple stages of learning to swim. The exemplary embodiments disclosed in this application are subject to various substitutions, combinations, and modifications. All such variations remain within the scope of this application and fall within the scope of protection defined by the claims of this application without departing from the essence of this application.
