Description

Technical Field

[0001] This utility model relates to the field of rescue clothing technology, specifically to a rope-rappelling one-piece suit. Background Technology

[0002] During rappelling operations, workers must utilize specialized equipment such as rappelling harnesses and ropes to perform complex maneuvers including suspension, climbing, turning, and material transfer at high altitudes. The unique working environment and the complexity of these movements place extremely high demands on the comprehensive performance of the coveralls worn. Coveralls not only need to provide basic protection but also must be well-fitted to the rappelling equipment to ensure its stable operation. Simultaneously, they must balance structural robustness with flexibility of movement to avoid design flaws that could affect work efficiency or create safety risks. Therefore, the structural design and performance of the coverall directly impact the worker's operational safety and ease of use.

[0003] To meet the basic protection requirements during rappelling operations, existing coveralls are mostly made of fabrics with a certain degree of abrasion resistance to reduce friction and wear between the clothing and ropes / equipment during operations, thus extending the garment's lifespan. Some products have pockets in the chest and hip areas for storing small tools, work records, and other items, improving the ease of access during operations. Additionally, some coveralls have elasticated cuffs and waistbands to improve the fit and reduce the entry of external debris, providing a relatively comfortable wearing experience for workers. These designs, to a certain extent, meet the basic requirements of rappelling operations, providing necessary protection and convenience for workers.

[0004] However, existing rappelling bodysuits lack in-depth structural design optimization specifically for the characteristics of rappelling operations, and still have many shortcomings, failing to adequately meet the professional needs of rappelling special operations. Firstly, existing bodysuits lack a structure designed to adapt to rappelling safety harnesses; workers typically wear the harness directly on the outside of the bodysuit, which not only affects operational flexibility but may also cause safety hazards due to harness displacement under stress. Secondly, regarding limb movement adaptability, existing bodysuits do not consider the need for workers to perform large-amplitude movements such as bending over, leaning back, and raising arms, resulting in a feeling of tightness in the back fabric during operations, restricting limb movement and hindering the smooth completion of complex movements. These shortcomings make it difficult for existing rappelling bodysuits to fully play their role in assisting operations and ensuring safety in practical applications. Utility Model Content

[0005] To address the technical problem that existing engineering work suits lack a design that adapts to safety belts and easily restricts the range of motion of workers' limbs, thus failing to meet the technical requirements of rappelling operations, this utility model provides a rappelling-style coverall. This rappelling coverall is compatible with rappelling safety belts, allowing workers to easily adjust the position of equipment and clothing while reducing the restriction of limb movement by clothing. This helps to improve the ease of operation, flexibility of movement, and safety of rappelling.

[0006] The technical solution of this utility model is as follows: A rappelling-style bodysuit includes a front upper body, a front lower body, a back upper body, a back lower body, and two sleeves connected to each other. The front upper body has symmetrical under-shoulder openings on both sides, and the front lower body has symmetrical under-waist openings on both sides. The front upper body has a safety belt exit, which includes a left chest belt exit, a right chest belt exit, a left waist belt exit, and a right waist belt exit. The front upper body has a waist metal ring exit on each side, and the back upper body has a back metal ring exit. The back upper body is spliced ​​with an elastic fabric piece, which is located below the back metal ring exit, and the inside of the elastic fabric piece has a corresponding movable pleat structure.

[0007] Furthermore, the front upper body includes a left placket and a right placket, which are closed by a zipper.

[0008] Furthermore, a windproof structure is provided at the zipper location.

[0009] Furthermore, the windproof structure is located on one side of the left and right plackets, and is attached to the other side of the left and right plackets by Velcro.

[0010] Furthermore, a shielding structure, such as a flip cover, is provided at the opening below the shoulder.

[0011] Furthermore, flap pockets with flaps are provided on the front upper body, back lower body, and / or sleeves.

[0012] Furthermore, elastic band channels are provided around the cuff of the sleeve, and elastic bands are fixed in the elastic band channels, so that the cuff is tightened by the elastic bands.

[0013] Furthermore, the pleated structure allows for an 8-10 cm pleat allowance.

[0014] The beneficial effects of this utility model are as follows: The rappelling bodysuit provided by this utility model features symmetrically arranged under-shoulder and under-waist openings, allowing workers to easily reach inside the bodysuit to adjust the safety belt and inner clothing, thus improving operational convenience. The safety belt insertion and securing mechanisms, corresponding to the location of the rappelling safety belt, enable precise insertion and securing of the safety belt, further enhancing safety during rappelling operations. The elastic fabric panel on the back upper body, combined with the inner pleated structure, allows for flexible expansion and contraction with the movement of the back, reducing the restriction of limb movement by the clothing. Overall, this improves the flexibility of movement and equipment adaptability during operations, meeting the comprehensive requirements of safety, convenience, and flexibility for rappelling operations.

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Example 1 like Figure 1 , Figure 2As shown, a rappelling-style bodysuit includes a front upper body 1, a front lower body 12, a back upper body 15, a back lower body 11, and two sleeves 13, all connected by double-stitched seams to ensure structural strength. The front upper body 1, front lower body 12, back upper body 15, back lower body 11, and two sleeves 13 are all made of anti-static and flame-retardant fabric. This fabric primarily uses cotton, cotton-polyester blends, and cotton-nylon blends as its base layer, and achieves double protection through a composite structure of conductive and flame-retardant fibers. Anti-static and flame-retardant fabric is existing technology and can be procured according to actual needs.

[0021] The front upper body 1 of the rappelling jumpsuit includes a left placket and a right placket, which are closed by a resin zipper. A windproof structure 7 is installed at the zipper, located on one side of the left or right placket and attached to the other side of the left or right placket with Velcro. This effectively prevents external airflow from entering the garment through the zipper gaps. At the same time, the windproof structure 7 further enhances the sealing effect at the zipper, preventing rainwater, snow particles, and other liquid or solid debris from seeping in through the zipper gaps, keeping the inner garments dry, and ensuring that workers can maintain a good working condition in complex weather conditions, reducing the impact of environmental factors on work efficiency. In addition, the windproof structure 7 also protects the zipper, preventing friction from the working environment that could damage it.

[0022] The front upper body panel 1 of the rappelling suit has symmetrical under-shoulder openings on both sides, allowing workers to easily adjust the position of the chest strap of the rappelling harness while wearing the suit without removing it. This improves the convenience of harness adjustment and reduces downtime. The edges of the under-shoulder openings are bound to prevent fabric from fraying. Correspondingly, a cover structure, such as a flap 2, is provided at the under-shoulder openings to prevent external dust, debris, rainwater, etc., from entering the suit through the openings. This also prevents the fabric edges at the openings from wearing out or fraying due to long-term exposure, extending the service life of the openings. The front upper body 1 is provided with a safety belt insertion outlet 4. The edges of the safety belt insertion outlet 4 are edge-bound and the ends are additionally knotted. The safety belt insertion outlet 4 includes two chest belt insertion outlets (left chest belt insertion outlet and right chest belt insertion outlet) symmetrically located at the chest position of the front upper body 1, and two waist belt insertion outlets (left waist belt insertion outlet and right waist belt insertion outlet) symmetrically located at the waist position of the front upper body 1. Each of the two waist belt insertion outlets is also provided with a waist metal ring insertion outlet 5 on its outer side. The edges of the waist metal ring insertion outlet 5 are edge-bound and the ends are additionally knotted. The chest belt, waist belt and metal ring of the rappelling safety belt can be passed through the corresponding insertion outlets, which helps to improve the fit between the rappelling safety belt and the human body, thereby improving the safety of rappelling operations. Preferably, a reinforcing loop can also be provided at the waist metal ring insertion outlet 5. The end of the reinforcing loop is glued and fixed with high-strength Velcro, which can play a role in fixing the waist metal ring. The front upper body 1 also features two symmetrically positioned front chest pockets 3, which are covered pockets that provide storage space.

[0023] The back upper body 15 of the rappelling suit is provided with a back metal ring outlet 9, which facilitates the metal ring of the rappelling harness strap to pass through. The edge of the back metal ring outlet 9 is edged and the end is additionally knotted. Preferably, a reinforcing loop can also be provided at the back metal ring outlet 9. The end of the reinforcing loop is glued and fixed with high-strength Velcro, which can fix the back metal ring. Below the metal ring exit 9 on the back, there is an elastic fabric piece 8 on the upper back panel 15. This piece can elastically deform with the back movements of the worker, such as bending over or leaning back, reducing the restriction of the clothing on the back muscles and allowing for more freedom of movement. The inner side of the elastic fabric piece 8 has a corresponding pleated structure with a pleat allowance of 8-10 cm. This pleat allowance is further coordinated with the stretching and contraction of the elastic fabric piece 8. When the range of motion is large, the pleat allowance is released to prevent the fabric of the upper back panel 15 from becoming too tight due to excessive stretching. This ensures that the limbs can move freely without restricting the range of motion. When the movement returns to normal, the pleat allowance is reduced to keep the garment's appearance flat.

[0024] The lower front panel 12 of the rappelling suit has symmetrical waist openings 6 on both sides, which makes it easy for workers to reach out and adjust the position of the rappelling safety belt or the position of the inner clothing. The edges of the waist openings 6 are bound to prevent the fabric from coming loose.

[0025] The lower back panel of the rappelling bodysuit has two hip pockets 10 at the hip position. The hip pockets 10 are flap pockets with lids, providing storage space.

[0026] The sleeves 13 of the rappelling bodysuit have elastic band channels around their cuffs, with elastic bands fixed within these channels. The cuffs are tightened by these elastic bands, and the elasticity of the bands allows the cuffs to adapt to workers with different wrist sizes, ensuring a snug and comfortable fit. The tightened cuffs prevent the sleeves 13 from slipping upwards during work due to large movements, ensuring that the sleeves 13 always cover the arms and prevent friction damage from direct contact between the skin and ropes / equipment. They also prevent external debris such as dust, gravel, and rainwater from entering the sleeves 13 through the cuffs. Preferably, the elastic bands are wide, high-elasticity elastic bands with an elastic recovery rate of ≥95%. An arm pocket 14 with a flap is located at the upper arm position of one of the sleeves 13, providing storage space.

[0027] The method of using the rappelling bodysuit and rappelling safety harness of this utility model is as follows: A rappelling harness includes a back strap, a chest strap, and a waist belt. There are two back straps, which cross at the back with metal loops at the crossover point. The front ends of the two back straps are connected to the left and right sides of the front of the waist belt, respectively, and the rear ends are connected to the left and right sides of the rear of the waist belt, respectively. The waist belt has metal loops on both sides. The two ends of the chest strap connect to the front of the two back straps. Both the chest strap and the waist belt are adjustable in length. The back and waist metal loops are used to connect to rappelling equipment. In some cases, the rappelling harness may also include two leg straps, each connected to the waist belt via two cross straps.

[0028] The worker first puts on the rappelling harness, then on the rappelling bodysuit. The two ends of the chest strap of the rappelling harness are threaded through the two chest strap openings located at the chest position on the front upper body 1 of the rappelling bodysuit, and then the buckles at both ends of the chest strap are fastened. The two ends of the waist belt of the rappelling harness are threaded through the two waist belt openings located at the waist position on the front upper body 1 of the rappelling bodysuit, and then the buckles at both ends of the waist belt are fastened. The waist metal loop of the rappelling harness is threaded through the two waist metal loop openings 5 ​​located at the waist position on the front upper body 1 of the rappelling bodysuit. The back metal loop of the rappelling harness is threaded through the back metal loop opening 9 located on the back upper body 15 of the rappelling bodysuit.
