Description

Technical Field

[0001] This invention relates to the field of vest technology, and in particular to a fully enclosed thermal vest. Background Technology

[0002] A vest is a sleeveless, short top that primarily covers the front and back of the wearer's torso, providing basic warmth while freeing the arms for movement. Common types include suit vests, cotton vests, down vests, and knitted vests. With technological advancements, vests with specific functions have also emerged, such as vests with heating elements (graphene) or vests with integrated protective airbags.

[0003] However, due to structural limitations, the biggest drawback of traditional vests is their open armholes (cuffs). When worn in cold environments, cold air can easily enter through these areas, directly affecting the wearer's armpits, sides, and core abdominal area, causing significant heat loss and severely weakening the vest's overall warmth retention.

[0004] While some existing designs attempt to add thermal sleeves or detachable shawl-like components to the shoulder and sleeve areas, these solutions typically suffer from the following shortcomings: 1) The added components often need to be stored completely separately, which makes them easy to lose and inconvenient to retrieve and connect; 2) The fixation and wrapping methods are mostly simple sleeves or straps, which do not fit the arm well, and there are still gaps that cause air leakage, or excessive binding affects the blood circulation and flexibility of the arm. 3) When not in use, external parts usually cannot be neatly stored together with the main body of the vest, affecting the appearance of the garment and reducing the convenience and aesthetics of daily wear.

[0005] Therefore, how to design a warm vest that can effectively solve the problem of air getting into the cuffs and achieve efficient dynamic sealing, while also allowing for convenient and neat switching between warm and regular modes, has become a pressing technical problem in this field. Summary of the Invention

[0006] Therefore, it is necessary to address the aforementioned technical issues by providing a fully enclosed thermal vest. This vest features an innovative "inflatable cuff wrap unit" design, which can be pulled out from the storage unit at the cuff and unfolded to cover the upper arm area when needed. Independent inflation units (such as manually inflatable bladders) inflate the internal folded storage sleeve loop and cuff wrap loop, expanding them into a ring-shaped air chamber that adaptively conforms to the arm's contours. This inflatable fit tightly wraps around users with different arm sizes, maintaining a good dynamic seal even during arm movement, fundamentally preventing cold air from entering through the cuffs and significantly improving the warmth retention efficiency of the core torso area.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A fully enclosed thermal vest includes a vest body, with cuffs on both sides of the vest body. A storage unit is connected to the cuff, and a cuff wrapping unit is provided inside the storage unit. Inflatable units are distributed at the bottom of both sides of the front of the vest body. The cuff wrapping unit includes a folding and storage sleeve loop and a cuff wrapping loop connected to the end of the folding and storage sleeve loop, and the folding and storage sleeve loop and the cuff wrapping loop are internally connected to each other. The cuff wrapping ring has a first drawstring inside, and both ends of the first drawstring pass through the outside of the cuff wrapping ring and are connected to a first drawstring fixing buckle. Under the action of the inflation unit, the folded storage cuff ring and the cuff wrapping ring can be inflated and wrapped around the upper arm to form a seal.

[0008] Furthermore, a first storage part is fixed at the outer edge of the cuff, and a second storage part is fixed at the inner edge of the cuff. A male Velcro patch is fixed on the inner side of the first storage part, and a female Velcro patch is fixed on the outer side of the second storage part. The first and second storage parts can be glued together by the male and female Velcro patches to form a wrap around the stored cuff wrapping unit.

[0009] Furthermore, the cuff portion has a storage cavity on one side, the inner end of the folded storage sleeve ring portion is located between the first storage portion and the second storage portion and is fixed in the storage cavity, and an annular inflation tube is also provided inside the cuff portion, the annular inflation tube being interconnected with the end of the folded storage sleeve ring portion.

[0010] Furthermore, the storage cavity is also provided with a second drawstring, which is distributed in a ring around the circumference of the cuff and has both ends extending outward through the cuff and connected to a second drawstring fixing buckle.

[0011] Furthermore, the surface of the cuff is provided with an extension groove, and the second drawstring fixing buckle extends out of the outside of the cuff through the extension groove; The first drawstring fixing buckle and the second drawstring fixing buckle have the same structure.

[0012] Furthermore, the middle of the front of the vest is connected by a zipper assembly, which divides the vest into a left vest section and a right vest section. The cuffs of the left vest section and the right vest section are respectively set to correspond to the inflation unit below.

[0013] Furthermore, the inflation unit includes a detachable air bladder embedded inside the left or right vest section and an air supply pipe connected to the detachable air bladder, with one end of the air supply pipe extending into the corresponding storage unit and connected to the storage unit.

[0014] Furthermore, the second drawstring fixing buckle includes a housing and a movable cavity opened inside the housing. A locking seat is slidably provided in the movable cavity. Two parallel locking holes are opened on the surface of the locking seat, and the second drawstring passes through the locking holes. The housing has a clearance groove at one end, a push-button movably disposed within the clearance groove, a locking seat fixed to the push-button via a connecting rod, and a spring connected to the side wall of the housing at one end.

[0015] Furthermore, the surface of the housing is provided with an external locking hole corresponding to the locking hole. Under the action of the spring, the locking hole and the external locking hole can be staggered to form a positioning of the second pull rope. The protruding groove is adapted to the shape of the housing.

[0016] Furthermore, the vest body includes an inner layer, a filling layer, and an outer layer, which are stacked sequentially and sewn together at the edges; The inner layer, filling layer and outer layer are made of synthetic fiber, down and nylon fiber blend, respectively. The folding storage sleeve loop and the cuff wrapping loop are made of the same material; The foldable storage sleeve includes an outer layer, a middle layer, and an inner layer. The outer layer is made of thermoplastic polyurethane, the middle layer is made of a mesh fabric woven from high-strength polyester or nylon fibers, and the inner layer is made of TPU or PVC.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a full-coverage thermal vest with an innovative "inflatable cuff wrap unit" design. When needed, it can be pulled out from the storage unit at the cuff and unfolded to cover the upper arm area. An independent inflation unit (such as a manually inflatable bladder) inflates the internal folded storage sleeve loop and cuff wrap loop, expanding them into a ring-shaped air chamber that adaptively conforms to the arm's contours. This inflatable fit tightly wraps around users with different arm sizes, maintaining a good dynamic seal even during arm movement. It fundamentally eliminates the pathway for cold air to enter through the cuffs, significantly improving the warmth retention efficiency of the core torso area.

[0018] When not in use, the inflatable sleeves of this invention can be completely folded and stored in a specially designed interlayered storage cavity at the cuff of the vest. Through the Velcro fastening of the first and second storage sections, and the tightening of the second drawstring built into the cuff, the stored components can be securely and neatly fixed inside the cuff, restoring the vest to a standard, clean, and conventional appearance with virtually no extra protrusions. This design achieves a quick and convenient switch between a "fully enclosed, warm mode" and a "conventional vest mode" without requiring the separation and storage of any parts, greatly improving ease of use and the versatility and aesthetics of everyday wear.

[0019] The cuff wrapping loop has a first drawstring at its end, which can be finely adjusted and locked at the inflated upper arm wrapping port to prevent slippage. The cuff itself has a second drawstring, which can tighten the cuff for wind protection in the normal state, and in the stored state, it acts as a "tightening strap". It works with the extension slot and the external second drawstring fixing buckle acts as a limiting buckle to form a firm restraint on the stored sleeve. One drawstring serves multiple purposes.

[0020] The inflation unit combines a detachable air bladder with an air delivery tube, integrated on both sides of the vest's hem. The placement is logical and the operation is convenient. The detachable air bladder facilitates maintenance and replacement. The air delivery tube connects to the inner cavity of the sleeve via a ring-shaped inflation tube at the cuff, ensuring even and efficient inflation. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] Example 1 Please refer to Figures 1-11 A fully enclosed thermal vest includes a vest body 1, with cuffs 11 on both sides of the vest body 1, a storage unit 2 connected to the cuffs 11, a cuff wrapping unit 3 inside the storage unit 2, and an inflation unit 4 distributed at the bottom of both sides of the front of the vest body 1. The cuff wrapping unit 3 includes a folding and storage sleeve loop portion 31 and a cuff wrapping loop portion 32 connected to the end of the folding and storage sleeve loop portion 31. The folding and storage sleeve loop portion 31 and the cuff wrapping loop portion 32 are internally connected to each other. The cuff wrapping ring 32 is provided with a first drawstring 33 inside. Both ends of the first drawstring 33 pass through the outside of the cuff wrapping ring 32 and are connected to a first drawstring fixing buckle 5. Under the action of the inflation unit 4, the folded storage cuff ring 31 and the cuff wrapping ring 32 can be inflated and wrapped around the upper arm to form a seal.

[0025] This embodiment features an innovative "inflatable cuff wrap unit" design. When needed, it can be pulled out and unfolded from the storage unit 2 in the cuff section 11 to cover the upper arm area. An independent inflation unit 4 inflates the internal folded storage sleeve loop 31 and cuff wrap loop 32, expanding them into a ring-shaped air chamber that adaptively conforms to the arm's contour. This inflatable fit tightly wraps around users with different arm sizes, maintaining a good dynamic seal even during arm movement. This fundamentally eliminates the pathway for cold air to enter through the cuff, significantly improving the warmth retention efficiency of the core torso area.

[0026] Example 2 The full-coverage thermal vest provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 4 As shown, a first storage part 110 is fixed at the outer edge of the cuff portion 11, and a second storage part 111 is fixed at the inner edge of the cuff portion 11. A male Velcro patch is fixed to the inner side of the first storage part 110, and a female Velcro patch is fixed to the outer side of the second storage part 111. The first storage part 110 and the second storage part 111 can be glued together by the male and female Velcro patches to form a wrapping and storage of the stored cuff wrapping unit 3.

[0027] The cuff portion 11 has a storage cavity 113 on one side. The inner end of the folded storage sleeve ring portion 31 is located between the first storage portion 110 and the second storage portion 111 and is fixed in the storage cavity 113. An annular inflation tube 112 is also provided inside the cuff portion 11. The annular inflation tube 112 is connected to the end of the folded storage sleeve ring portion 31.

[0028] In this embodiment, the cuff wrapping unit 3 can be completely folded and stored in the specially designed interlayered storage cavity 113 of the vest cuff 11 when not in use. Through the Velcro fastening of the first storage part 110 and the second storage part 111, the stored components can be securely and neatly fixed inside the cuff, instantly restoring the vest to a standard, neat, and conventional appearance with almost no extra protrusions. This design achieves a quick and convenient switch between a "fully wrapped warming mode" and a "conventional vest mode" without the need to separate any parts for storage, greatly improving ease of use and the versatility and aesthetics of everyday wear.

[0029] Example 3 The full-coverage thermal vest provided in Embodiment 1 or 2 has been further optimized, such as... Figure 9 As shown, the storage cavity 113 is also provided with a second drawstring 114. The second drawstring 114 is distributed in a ring along the circumference of the cuff portion 11, and both ends extend through the cuff portion 11 to the outside and are connected to a second drawstring fixing buckle 6.

[0030] The cuff portion 11 has an extension groove 115 on its surface, and the second drawstring fixing buckle 6 extends out of the outside of the cuff portion 11 through the extension groove 115. The first drawstring fixing buckle 5 and the second drawstring fixing buckle 6 have the same structure.

[0031] The cuff wrapping loop 32 has a first drawstring 33 at its end, which can be finely adjusted and locked at the inflated upper arm wrapping port to prevent slippage. The cuff itself has a second drawstring 114, which can tighten the cuff 11 for wind protection in the normal state, and acts as a "tightening strap" in the stored state. It cooperates with the extension slot 115 to use the external second drawstring fixing buckle 6 as a limiting buckle to form a stable constraint on the stored cuff wrapping unit 3. One rope serves multiple purposes.

[0032] Example 4 The full-coverage thermal vest provided in Embodiment 3 has been further optimized, such as... Figure 1 The vest body 1 shown is connected in the middle of the front by a zipper assembly 12. The zipper assembly 12 causes the vest body 1 to be divided into a left vest part 13 and a right vest part 14. The cuffs 11 on the left vest part 13 and the right vest part 14 are respectively set to correspond to the inflation unit 4 below.

[0033] The inflation unit 4 includes a detachable airbag 41 embedded inside the left vest 13 or the right vest 14 and an air supply pipe 42 connected to the detachable airbag 41. One end of the air supply pipe 42 extends into the corresponding storage unit 2 and is connected to the storage unit 2.

[0034] The air supply tube 42 and the detachable air bladder 41 are detachably connected. Pressing the detachable air bladder 41 allows the gas inside to be supplied to the storage unit 2 through the air supply tube 42, so that the folded storage sleeve loop 31 and the cuff wrapping loop 32 are both inflated. The inflated folded storage sleeve loop 31 and the cuff wrapping loop 32 can adapt to the shape of the upper arm and fit accordingly, thereby achieving wrapping in that area and providing an overall sealing and warmth effect.

[0035] Example 5 The full-coverage thermal vest provided in Example 4 has been further optimized, such as... Figure 11As shown, the second drawstring fixing buckle 6 includes a housing 61 and a movable cavity 62 opened inside the housing 61. A locking seat 63 is slidably provided in the movable cavity 62. Two parallel locking holes 64 are opened on the surface of the locking seat 63. The second drawstring 114 passes through the locking holes 64. The housing 61 has a clearance groove 65 at one end, and a push buckle 66 is movably disposed in the clearance groove 65. The locking seat 63 is fixed to the push buckle 66 by a connecting rod 67, and a spring 68 connected to the side wall of the housing 61 is connected to one end of the locking seat 63.

[0036] Press the snap fastener 66 to engage it and place it inside the corresponding clearance groove 65. This allows the locking seat to slide inside the housing 61, compressing the spring 68. This aligns the locking hole 64 with the outer locking hole 69 on the surface of the housing 61, allowing the second pull rope 114 to be freely pulled and its length to be adjusted. Similarly, the adjustment method for the first pull rope fixing buckle 5 is the same.

[0037] The surface of the housing 61 is provided with an outer locking hole 69 corresponding to the locking hole 64. Under the action of the spring 68, the locking hole 64 and the outer locking hole 69 can be staggered to form a positioning of the second pull rope 114. The protrusion groove 115 is adapted to the shape of the housing 61.

[0038] The specific application methods for the storage unit and cuff wrapping unit 3 are as follows: like Figure 1 , Figure 7 and Figure 8 As shown in the conventional form: the cuff wrapping unit 3 is folded and stored in the storage cavity 113 of the cuff part 11, and is sealed by the Velcro fasteners of the first storage part 110 and the second storage part 111. The second drawstring 114 is pulled out of the outside of the cuff part 11, thereby achieving a further invisible positioning effect for the stored cuff wrapping unit 3, so that the vest maintains a neat appearance.

[0039] like Figure 2 , Figure 3 and Figure 4 To convert to full-coverage mode: Open the male / female Velcro straps, press the snap 66 to move it into the clearance groove 65. At this time, the shell 61 can completely pass through the extension groove 115, allowing it to be moved into the storage cavity 113. Then, pull out the cuff wrapping unit 3 from the storage cavity 113, unfold it, and put it on the upper arm. Adjust the first pull cord 33 to make the cuff wrapping ring 32 fit the arm. Then, press the detachable air bladder 41 in the inflation unit 4. Gas enters the sleeve through the air supply tube 42 and the annular inflation tube 112, inflating and expanding it to tightly wrap the arm, forming a windproof and sealed structure.

[0040] To restore the normal shape: Press the exhaust valve (not shown in the figure) on the inflatable bladder to release the gas, remove the cuff wrapping unit 3 from the arm, fold it and put it back into the storage cavity 113. Close the Velcro of the first storage part 110 and the second storage part 111, tighten the second drawstring 114 and snap the second drawstring fixing buckle 6 into the extension slot 115 to complete the storage.

[0041] This invention cleverly combines inflatable sleeves with concealed storage, achieving excellent dynamic sealing and warmth while maintaining the vest's lightweight and flexible characteristics. It can also be quickly and neatly switched between two usage modes, making it suitable for various scenarios such as outdoor activities and daily commutes.

[0042] Example 6 The full-coverage thermal vest provided in Example 5 has been further optimized, such as... Figure 10 As shown, the vest body 1 includes an inner layer 15, a filling layer 16 and an outer layer 17, which are stacked in sequence and sewn together at the edges; The inner layer 15, the filling layer 16 and the outer layer 17 are made of synthetic fiber, down and nylon fiber blend, respectively. The folding storage sleeve loop 31 and the cuff wrapping loop 32 are made of the same material; The foldable storage sleeve 31 includes an outer layer, a middle layer, and an inner layer. The outer layer is made of thermoplastic polyurethane, the middle layer is made of a mesh fabric woven from high-strength polyester or nylon fibers, and the inner layer is made of TPU or PVC.

[0043] Based on any previous embodiment, this embodiment specifically describes the material structure of the vest body and sleeves. The vest body 1 includes an inner layer 15, a filling layer 16, and an outer layer 17, which are stacked sequentially and sewn together at the edges. The inner layer 15 is made of synthetic fiber, the filling layer 16 is made of down, and the outer layer 17 is made of a nylon fiber blend fabric, which combines skin-friendliness, lightness, warmth, and abrasion resistance.

[0044] The folding storage sleeve loop 31 and the cuff wrapping loop 32 are made of the same material, both being composite laminate structures. The inner layer uses TPU or PVC, thereby ensuring airtightness and flexibility while enhancing its tensile and fatigue resistance.
