Description

Technical Field

[0001] This utility model relates to the field of workwear technology, and in particular to a body-fitting one-piece workwear suitable for operation in confined spaces. Background Technology

[0002] In work scenarios requiring frequent bending, such as ship welding and equipment maintenance, one-piece protective suits have become the mainstream choice due to their overall sealing properties. However, traditional one-piece suits often use a single elastic fabric or a fixed pleat design to accommodate waist movement, which has significant drawbacks:

[0003] Elasticity decay and protection conflict: Although the waistband, which relies on elastic fabric, can provide basic stretchability, long-term stretching can easily lead to material fatigue and decreased elasticity. In addition, high-elastic fabrics usually have insufficient flame retardant properties, making it difficult to meet the protection requirements of high-temperature operations.

[0004] Insufficient dynamic fit: Although the horizontal pleat design with fixed pleat amount can provide limited extension, its distribution density and pleat amount are not adapted to the maximum elongation of the waist skin when the human body bends over (usually 7-12cm), resulting in tightness at the waist when bending over and redundant accumulation of clothing pleats after standing up, affecting the smoothness of movement and the speed of clothing recovery.

[0005] Multi-layer structure interference: Some solutions attempt to lining the waist with an independent elastic band, but the extra structure increases the thickness of the clothing, creating interlayer friction when bending over, which in turn exacerbates the feeling of restriction during movement.

[0006] Therefore, there is an urgent need for a waist structure design that takes into account protection, dynamic fit, and rapid recovery capability, in order to overcome the bottleneck of adaptability of one-piece protective suits under extreme working postures. Utility Model Content

[0007] The purpose of this invention is to solve the problems existing in the prior art by proposing a body-fitting one-piece workwear suitable for operation in confined spaces.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A body-fitting onesie suitable for operation in confined spaces includes a main body of the workwear. The back waist of the main body of the workwear has several parallel horizontal accordion pleats. Each horizontal accordion pleat extends horizontally along the lumbar spine axis of the human body. The pleats are integrally formed by hot pressing and bonding an outer aramid protective fabric layer and an inner high-elastic knitted fabric layer.

[0010] Preferably, there are 7 horizontal accordion pleats, and the pleat of a single horizontal accordion pleat is 1.5cm, with a total extension length of 10.5cm.

[0011] Preferably, the back area of ​​the workwear body is symmetrically provided with two sets of longitudinal accordion pleats along the direction of movement of the two scapulae, and the pleat of a single longitudinal accordion pleat is 6cm.

[0012] Preferably, the collar of the work uniform body adopts an adjustable stand-up collar structure, and a drawstring assembly is embedded in the collar to achieve tightness adjustment.

[0013] Preferably, the height of the adjustable stand-up collar structure is 6.5cm.

[0014] Preferably, reflective strips are provided on the cuffs, lower back, shoulders, upper chest, and trouser legs of the main body of the work uniform.

[0015] Preferably, the main body of the workwear adopts a front-part design, with the parted areas set along the front center line of the human body to form an openable placket. The upper end of the openable placket starts at the top of the adjustable stand-up collar structure and the lower end ends at the crotch. The openable placket is fixed by Velcro.

[0016] Preferably, the knee area of ​​the workwear body is provided with a removable cushioning pad, which is connected to the knee area of ​​the workwear body by Velcro, and the cushioning pad is filled with fire-retardant sponge.

[0017] Preferably, the outer end of the trouser leg of the work uniform body is closed by a zipper structure, and the outer side of the trouser leg is provided with a Velcro closure for adjusting the tightness of the trouser leg.

[0018] Preferably, the trouser legs of the work uniform body are designed with an arc-shaped front cuff.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention, through a composite design of horizontal accordion pleats and a high-elastic lining, maintains the slim fit of the bodysuit while dynamically matching the skin deformation trajectory of the waist during bending and stretching. This completely solves the problems of movement stagnation and redundant clothing pleats caused by rigid waist size limitations, while also taking into account protection, dynamic fit, and quick recovery capability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-3 A body-fitting onesie workwear suitable for operation in confined spaces includes a workwear body 1. The back waist of the workwear body 1 is provided with several parallel horizontal accordion pleats 2. Each horizontal accordion pleat 2 extends horizontally along the lumbar spine axis of the human body. The horizontal accordion pleats 2 are integrally formed by hot pressing and bonding an outer aramid protective fabric layer 3 and an inner high-elastic knitted fabric layer 4.

[0027] The horizontal accordion pleats 2 are provided with 7 pleats, and the pleat amount of each horizontal accordion pleat 2 is 1.5cm, with a total extension length of 10.5cm.

[0028] This application features 7 transverse folds covering the key active area from the lumbar spine to the ilium. The design of 1.5cm per fold precisely matches the average elongation requirement of the lumbar skin when bending over (approximately 1.2-1.8cm / fold), and the total extension of 10.5cm can fully meet the lumbar expansion space under the maximum working posture.

[0029] Meanwhile, the outer aramid fabric maintains flame-retardant protection performance, while the inner high-elastic knitted fabric layer 4 provides radial rebound force through its high breaking elongation. When bending over, the pleats are allowed to unfold and release tension, and when standing up, the inner elasticity is used to quickly pull the pleats back to their original position, avoiding redundant deformation of the garment.

[0030] The aforementioned composite structure avoids the cutting effect of traditional sewing seams on elastic surfaces, ensuring coordinated deformation of inner and outer layers during pleat unfolding / resetting, and reducing motion interference caused by interlayer friction;

[0031] In addition, the waist of the work clothes can be designed with an elastic band to facilitate work in small spaces;

[0032] Compared to existing technologies, this application, through the composite design of horizontal accordion pleats 2 and high-elastic lining, maintains the slim fit of the bodysuit while dynamically matching the skin deformation trajectory of the waist bending and stretching. This completely solves the problems of movement jamming and redundant clothing pleats caused by the rigidity of waist size, while taking into account protection, dynamic fit and quick recovery ability.

[0033] In this embodiment, the back area of ​​the workwear body 1 is symmetrically provided with two sets of longitudinal accordion pleats 5 along the movement direction of the two scapulae. The material of the longitudinal accordion pleats 5 is the same as that of the transverse accordion pleats 2, and the pleat amount of a single longitudinal accordion pleat 5 is 6cm.

[0034] In this embodiment, the collar of the work uniform features an adjustable stand-up collar structure 6 with an embedded drawstring assembly 7. The drawstring is elastic, with both ends extending from inside the collar to the outer back of the collar and tied together. The tightness is adjusted by pulling the ends of the drawstring. The height of the adjustable stand-up collar structure 6 is 6.5cm. When tightened, the adjustable stand-up collar structure 6 forms a sealed protective interface with the neck skin, preventing welding sparks and dust from entering. This solves the risk of neck burns caused by the incomplete closure of the collar in traditional welding uniforms, while also ensuring flexibility and safety during high-risk upward-facing operations.

[0035] In this embodiment, reflective strips 8 are provided on the cuffs, back waist, shoulders, upper chest, and trouser legs of the workwear body 1, forming a warning area without blind spots in dark environments and improving passive visual safety when working in confined spaces.

[0036] In this embodiment, the workwear body 1 adopts a front split design and a back one-piece design. The split area is set along the front center line of the human body to form an openable placket 9. The upper end of the openable placket 9 starts from the top of the adjustable elastic stand-up collar structure 6 and ends at the crotch. The openable placket 9 is fixed by Velcro (not shown in the figure). The workwear body 1 adopts an integrated design of front split and back one-piece. While ensuring the continuity of the overall protection of the garment, the single-sided split greatly reduces the range of motion for putting on and taking off: the worker only needs to unfasten one side of the openable placket 9 to quickly put on and take off the garment, avoiding the cumbersome operation of traditional one-piece garments that require the whole body to be crawled into.

[0037] In this embodiment, a removable cushioning pad 10 is provided in the knee area of ​​the workwear body 1. The cushioning pad 10 is connected to the workwear body 1 via Velcro (the Velcro side is on the surface of the workwear body 1, and the Velcro side is at the rear of the cushioning pad 10 (not shown in the figure)). The cushioning pad 10 is filled with fire-retardant sponge (not shown in the figure). The removable cushioning pad 10, connected by Velcro, allows workers to flexibly replace or adjust the protection level according to actual working conditions. The fire-retardant sponge inside forms a heat-insulating cushioning layer in high-temperature environments, effectively absorbing the impact force when the knee comes into contact with hard objects, while blocking external heat from being conducted to the skin. Its modular design facilitates disassembly, cleaning, or replacement of damaged parts, significantly improving the maintenance efficiency and economy of the protective components.

[0038] In this embodiment, the outer end of the trouser leg of the workwear body 1 is closed by a zipper structure 11, and a Velcro fastener 12 is provided on the outer side of the trouser leg to adjust the tightness of the trouser leg. The combined design of the zipper closure structure and the Velcro fastener 12 achieves a tight fit between the trouser leg and the work boot through the zipper, preventing metal fragments or sparks from entering through the gaps in the trouser leg. The outer Velcro fastener 12 provides a graded tightness adjustment function (the Velcro fastener 12 has a Velcro loop side, one end of which is sewn to the trouser leg, and the corresponding Velcro bar side is sewn to the other side of the trouser leg), adapting to different boot heights and leg circumference sizes. While ensuring airtightness, it avoids poor blood circulation caused by the trouser leg being too tight, taking into account both protective safety and wearing comfort.

[0039] In this embodiment, the trouser legs of the workwear body 1 are designed with an arc-shaped front opening. After the zipper is opened, the size of the trouser leg increases. The arc-shaped front opening can cover the shoe opening more completely, preventing welding sparks or dust from entering the workwear body 1 or the inside of the shoes.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
