Description

Technical Field

[0001] This utility model relates to the field of thermal insulation technology, specifically to an ergonomically designed heated sock with an inner lining. Background Technology

[0002] During cold seasons, people with leg disabilities are prone to slowed blood flow and insufficient peripheral blood supply in their lower limbs due to nerve damage or reduced muscle activity. At the same time, limited mobility can significantly reduce muscle heat production and lower basal metabolic rate, all of which make them more susceptible to frostbite on their feet.

[0003] People with disabilities who rely heavily on wheelchairs are particularly prone to frostbite in cold environments due to limited leg movement. Traditional heating wires, due to their thickness, can be uncomfortable to wear. Therefore, we propose an ergonomically designed heated sock with an inner lining. Utility Model Content

[0004] The purpose of this invention is to provide an ergonomically designed heated sock with an inner lining to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ergonomically designed heated sock with an inner lining, comprising an inner lining, wherein a heating wire for foot heating is fixedly connected to one side of the inner lining, the heating wire comprising a foot arch segment located in the arch of the foot, the other end of the foot arch segment being fixedly connected to a sesamoid bone avoidance segment that avoids the sesamoid bone of the first metatarsal bone, the other end of the sesamoid bone avoidance segment being fixedly connected to a sesamoid bone arch segment passing through the distal joint of the first metatarsal bone and the distal joint of the second metatarsal bone, the other end of the sesamoid bone arch segment being fixedly connected to a middle phalanx segment, the other end of the middle phalanx segment being fixedly connected to a middle phalanx loop segment, the other end of the middle phalanx loop segment being fixedly connected to a lateral loop segment, the foot arch segment and the lateral loop segment being joined together to form a converging segment.

[0006] Preferably, the middle phalanx segment and the middle phalanx loop segment are distributed along the middle phalanx on the first to fifth metatarsal bones.

[0007] Preferably, the confluence segment extends along the inner side of the arch to the medial malleolus, and the other end of the confluence segment is fixedly connected to a plug for electrical connection.

[0008] Preferably, the plug is electrically connected to a plug port, one side of which is fixedly connected to a battery casing, and the plug port is located on the inner wall of one side of the battery casing. The plug passes through one side of the battery casing and is electrically connected to the plug port.

[0009] Preferably, a battery pack is fixedly connected to the inner wall of the other side of the battery casing, and the battery pack is electrically connected to the plug-in port.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution: such as Figures 1-5 The illustrated ergonomic heated sock includes an inner lining 1. A heating wire for foot heating is fixedly connected to one side of the inner lining 1. The heating wire includes a foot socket segment 2 located in the arch of the foot. The other end of the foot socket segment 2 is fixedly connected to a sesamoid bone avoidance segment 3 that avoids the sesamoid bone of the first metatarsal. The other end of the sesamoid bone avoidance segment 3 is fixedly connected to a sesamoid bone socket segment 4 passing between the distal joints of the first and second metatarsals. The other end of the sesamoid bone socket segment 4 is fixedly connected to a middle phalanx segment 5. The other end of the middle phalanx segment 5 is fixedly connected to a middle phalanx loop segment 6. The other end of the middle phalanx loop segment 6 is fixedly connected to a lateral loop segment 7. The foot socket segment 2 and the lateral loop segment 7 are joined together to form a confluence segment 8. During manufacturing, the inner lining 1 is sewn to the inner wall of the shoe, and the side of the heating wire away from the inner lining 1 is fixed to the inner wall of the bottom of the shoe sole. In use, it is electrically connected to a plug 18 via a connector 17, and the heating wire heats up when energized. The battery casing 9 is held at the edge of the shoe's inner ankle by a back clip 12: pressing the pinch plate 13 overcomes the force of the retaining spring 15, causing the back clip 12 to move closer to the battery casing 9, separating its clamping part from the outer wall of the battery casing 9; after inserting the clamping part into the inner ankle near the shoe opening, the retaining spring 15 releases potential energy, causing the back clip 12 to move closer to the battery casing 9, thus clamping it to the side of the shoe opening. Note that the user still needs to wear well-fitting warm socks, and these lining heated socks are not washable.

[0023] like Figure 1 and Figure 2 As shown, the middle phalanx segment 5 and the middle phalanx loop segment 6 are distributed along the middle phalanx from the first metatarsal to the fifth metatarsal.

[0024] like Figure 1 and Figure 2 As shown, the confluence segment 8 extends along the inner side of the foot socket to the medial malleolus, and the other end of the confluence segment 8 is fixedly connected to a plug 18 for electrical connection.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, plug 18 is electrically connected to plug port 17. A battery casing 9 is fixedly connected to one side of plug port 17, and plug port 17 is located on the inner wall of one side of battery casing 9. Plug 18 passes through one side of battery casing 9 and is electrically connected to plug port 17. The foot socket section 2 of the heating wire is routed in the concave area of ​​the sole of the foot, which can both heat and keep the foot warm and prevent foot discomfort. The sesamoid section 3 avoids the protruding part of the sesamoid bone to prevent the heating wire from compressing the sesamoid bone, improving foot comfort. Because the proximal and distal phalanges of humans protrude upwards through the middle phalanx, forming a continuous concave area between the sole and toes, the middle phalanx section 5 and the middle phalanx loop section 6 are routed in this concave area, which can both heat and keep the toes warm and prevent the heating wire from compressing the toes, further improving comfort.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a battery pack 16 is fixedly connected to the inner wall of the other side of the battery casing 9, and the battery pack 16 is electrically connected to the plug-in port 17.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, a hinge seat 10 is fixedly connected to one side of the battery casing 9. A fixed shaft 11 is fixedly connected inside the hinge seat 10. A back clip 12 is rotatably connected to the side surface of the fixed shaft 11. A pinch plate 13 is fixedly connected to the opposite side of the two back clips 12. A protrusion 14 is fixedly connected to one side of one of the back clips 12. A retaining spring 15 is sleeved on the outside of the fixed shaft 11. The two claws of the retaining spring 15 abut against the outer wall of the protrusion 14 and one side of the battery casing 9, respectively. Through the back clip 12 and the battery casing 9, the battery pack 16 can be fixed to the shoe opening, so that the battery pack 16 can be removed and charged through the plug port 17, thereby improving convenience.

[0028] Working principle: During processing, the lining 1 is sewn to the inner wall of the shoe, and the heating wire is fixed to the inner wall of the bottom of the sole on the side away from the lining 1. In use, it is electrically connected to the plug 18 through the insertion port 17, and the heating wire heats up when energized. The battery casing 9 is held at the edge of the shoe's inner ankle by the back clip 12: pressing the pinch plate 13 overcomes the force of the retaining spring 15, causing the back clip 12 to move closer to the battery casing 9, separating its clamping part from the outer wall of the battery casing 9; after inserting the clamping part into the inner ankle near the shoe opening, the retaining spring 15 releases potential energy, causing the back clip 12 to move closer to the battery casing 9, thus clamping it to the side of the shoe opening. Note that the user still needs to wear well-fitting warm socks, and these lining-type heated socks are not washable.
