Description

Technical Field

[0001] This invention relates to the field of protective and support equipment for workers, specifically to a portable inflatable support device for workers and its usage method. Background Technology

[0002] Currently, workers who stand for extended periods, such as in assembly line operations or high-altitude installations, experience continuous weight-bearing stress on their lower back, abdomen, and lower limbs, leading to muscle fatigue and excessive pressure on the lumbar spine. Over time, this can result in conditions like lumbar muscle strain and varicose veins in the lower extremities. Existing support devices are mostly rigid structures, which are inconvenient to carry, lack adaptability, cannot be adjusted for different body types, and offer low comfort. Some inflatable devices only target a single area, such as the lower back, providing insufficient stability and using rudimentary fixing methods that are prone to shifting during operation, failing to meet actual work requirements.

[0003] Therefore, a portable inflatable support device for workers and its usage method are provided. Summary of the Invention

[0004] The purpose of this invention is to provide a portable inflatable support device for workers and its usage method, so as to overcome the shortcomings of the prior art which only fixes a single part and has insufficient support stability and is prone to displacement during operation.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: In a first aspect, the present invention provides a portable inflatable support device for workers, comprising an inflatable support body, a human body fixing component, and an inflation component. The inflatable support body is a flexible, sealed structure. The human body fixing component consists of at least two sets, each connected to the edge region of the inflatable support body. At least one set of the human body fixing component is used to connect with the torso of the worker, serving to fix the torso and prevent displacement of the torso relative to the support device. At least one set of the human body fixing component is used to connect with the lower limbs of the worker, serving to fix the lower limbs and prevent displacement of the lower limbs relative to the support device. The inflation component is detachably connected to an air passage interface for inflating the inflatable support body. An air plug is provided at the air passage interface to seal the air passage after inflation, preventing gas leakage from the inflatable support body.

[0006] Furthermore, the human body fixation component includes a first buckle, a second buckle, a third buckle, and a fourth buckle; the first and second buckles constitute a first fixation group for connecting with the torso of the worker, and are symmetrically arranged on one side of the length direction of the inflatable support body; the third and fourth buckles constitute a second fixation group for connecting with the lower limbs of the worker, and are symmetrically arranged on the other side of the length direction of the inflatable support body.

[0007] Furthermore, the first, second, third, and fourth buckles are all self-adhesive buckles. Each self-adhesive buckle includes a strap body, a male adhesive surface at one end of the strap body, and a female adhesive surface at the other end. The male and female adhesive surfaces can be bonded together to achieve fixation. Through the bonding and separation of the male and female adhesive surfaces, the buckle can be quickly tightened and loosened, facilitating the quick fixation of the worker's body or the release of fixation.

[0008] Furthermore, the first, second, third, and fourth buckles are connected to the inflatable support body by sewing.

[0009] Furthermore, the four corners of the inflatable support body are all provided with rounded corner structures.

[0010] Furthermore, the inflation assembly is a manual air pump, which includes a cylinder, a piston rod, a piston, and an inflation connector. The outer diameter of the inflation connector is adapted to the inner diameter of the air passage interface, and the inflation connector and the air passage interface are detachably connected by an interference fit.

[0011] Furthermore, the air passage interface is made of copper or hard plastic, and the connection between the air passage interface and the inflatable support body is an embedded heat-sealing connection.

[0012] Furthermore, the surface of the inflatable support body is provided with an anti-slip texture.

[0013] Secondly, the present invention provides a method for using a portable inflatable support device for workers, which includes the following steps: The operator stands with the inflatable support body attached to the lower abdomen and front of the thighs. The upper part of the inflatable support body is fixed to the waist by at least one set of human fixation components for connecting the torso, and the lower part of the inflatable support body is fixed to the thighs by at least one set of human fixation components for connecting the lower limbs. Connect the inflation component to the air passage interface of the inflatable support body, start the inflation component to inflate the inflatable support body with gas until the inflatable support body expands to a state with supporting strength, disconnect the inflation component from the air passage interface and close the air plug at the air passage interface.

[0014] Furthermore, the inflation component is a manual air pump. The connection operation is as follows: insert the inflation connector of the manual air pump into the air passage interface, and achieve a sealed connection between the two through interference fit; the inflation operation is as follows: reciprocately push the piston rod of the manual air pump, so that gas enters the interior of the inflatable support body through the inflation connector and the air passage interface.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides a portable inflatable support device specifically for workers. The inflatable support body adopts a flexible, sealed structure, and can be folded and stored after deflation, significantly reducing its size, light weight, and ease of carrying. This solves the problem of poor portability of traditional rigid support devices, making it particularly suitable for mobile operations or scenarios requiring frequent movement, thus improving the portability for workers. At least two sets of body fixation components are respectively fixed to the worker's torso and lower limbs, providing targeted support for the lower abdomen and the front of the thighs, effectively distributing body pressure. This addresses the shortcomings of traditional devices that only fix a single area, lack sufficient support stability, and are prone to displacement during operation.

[0016] Specifically, the self-adhesive strap design allows for flexible length adjustment to fit workers of different body types, ensuring stable support and a close fit to the body, thus improving support effectiveness and wearing comfort. The wearing and inflation procedures are simple and clear, allowing workers to independently complete the entire process of securing, inflating, and storing the device without professional training, lowering the barrier to entry and improving work efficiency.

[0030] See Figure 1 and Figure 2 This invention provides a portable inflatable support device specifically for workers. The device includes an inflatable support body 2, a human body fixation component, and an inflation component. The inflatable support body 2 is a flexible, sealed structure used to form a supportive structure after inflation, providing a body support base for the worker. The human body fixation component consists of at least two sets, each connected to the edge area of ​​the inflatable support body 2. At least one set of the human body fixation component is used to connect to the worker's torso, fixing the torso and preventing displacement of the torso relative to the support device. At least one set of the human body fixation component is used to connect to the worker's lower limbs, fixing the lower limbs and preventing displacement of the lower limbs relative to the support device. The inflation component is detachably connected to an air passage interface 9, used to inflate the inflatable support body 2, causing it to expand and form a support structure. An air plug is provided at the air passage interface 9 to seal the air passage after inflation, preventing gas leakage from the inflatable support body 2.

[0031] In this embodiment, the inflation component is a manual air pump 1, which includes a cylinder, a piston rod, a piston, and an inflation connector 8. The outer diameter of the inflation connector 8 is adapted to the inner diameter of the air passage interface 9. The inflation connector and the air passage interface 9 are connected by an interference fit to achieve a detachable connection. The inflation connector 8 is used to connect with the air passage interface 9. The reciprocating motion of the piston rod and piston of the manual air pump 1 forces air into the inflatable support body 2 to achieve the inflation function.

[0032] In a more specific embodiment of the present invention, the human body fixation component includes a first buckle 3, a second buckle 4, a third buckle 5, and a fourth buckle 6; the first buckle 3 and the second buckle 4 constitute a first fixation group for connecting with the torso of the worker, symmetrically arranged on one side end of the length direction of the inflatable support body 2, and work together to surround and fix the torso of the worker; the third buckle 5 and the fourth buckle 6 constitute a second fixation group for connecting with the lower limbs of the worker, symmetrically arranged on the other side end of the length direction of the inflatable support body 2, and work together to surround and fix the lower limbs of the worker.

[0033] In a more specific embodiment of the present invention, the first buckle 3, the second buckle 4, the third buckle 5 and the fourth buckle 6 are all self-adhesive buckles. The self-adhesive buckle includes a belt body and a male adhesive surface at one end of the belt body and a female adhesive surface at the other end. The male adhesive surface and the female adhesive surface can be glued to each other to achieve fixation. Through the adhesion and separation of the male and female adhesive surfaces, the buckle can be quickly tightened and loosened, which facilitates the quick fixation of the worker's body or the release of fixation.

[0034] In a more specific embodiment of the present invention, the first buckle 3, the second buckle 4, the third buckle 5 and the fourth buckle 6 are connected to the inflatable support body 2 by sewing, which is used to firmly fix each buckle to the inflatable support body 2, ensuring that the buckles will not fall off when subjected to tension, and ensuring the fixing effect.

[0035] In a more specific embodiment of the present invention, the four corners of the inflatable support body 2 are provided with rounded corner structures to eliminate sharp corners and prevent the support device from scratching the skin of the worker 7 or snagging on clothing or equipment during use.

[0036] In a more specific embodiment of the present invention, the air passage interface 9 is made of copper or hard plastic. The air passage interface 9 is connected to the inflatable support body 2 by an embedded heat seal connection. The air passage interface 9 is used to provide an inflation channel and also serves as a connection interface for the inflation component. The embedded heat seal connection method can ensure the sealing and firmness of the connection between the air passage interface 9 and the inflatable support body 2.

[0037] In a more specific embodiment of the present invention, the surface of the inflatable support body 2 is provided with anti-slip texture to increase the friction between the operator's body and the surface of the support body, prevent the operator from sliding on the support device, and improve the stability of use.

[0038] The present invention also provides a method for using a portable inflatable support device for workers, which includes the following steps: The worker 7 maintains a standing posture, placing the inflatable support body 2 against their lower abdomen and the front of their thighs. The inflatable support body 2 is a flexible, sealed structure designed to provide support after inflation. The upper part of the inflatable support body 2 is secured to the waist via at least one set of body fixation components connecting to the torso, which secure the worker's torso and prevent displacement relative to the support device. Similarly, the lower part of the inflatable support body 2 is secured to both thighs via at least one set of body fixation components connecting to the lower limbs, which secure the worker's lower limbs and prevent displacement. The function of the support device displacement is as follows: The inflation component is connected to the air passage interface 9 of the inflatable support body 2. The air passage interface 9 is used to provide an inflation channel and serve as the connection interface of the inflation component; The inflation component is started to inflate the inflatable support body 2 with gas. The inflation component is used to inflate the inflatable support body 2 until the inflatable support body 2 expands to a state with supporting strength. The connection between the inflation component and the air passage interface 9 is disconnected and the air plug at the air passage interface 9 is closed. The air plug is used to seal the air passage and prevent gas leakage inside the inflatable support body 2. Finally, the inflatable support body 2 forms a stable support structure to provide body support for the workers.

[0039] Worker 7 maintains a standing posture, placing the inflatable support body 2 against the lower abdomen and front of the thighs. The inflatable support body 2 is a flexible, sealed structure designed to form a supportive structure after inflation. The upper part of the inflatable support body 2 is fixed to the waist via at least one set of body fixation components for connecting the torso, which secures the worker's torso and prevents displacement of the torso relative to the support device. The lower part of the inflatable support body 2 is fixed to both thighs via at least one set of body fixation components for connecting the lower limbs, which secures the worker's lower limbs and prevents displacement of the lower limbs relative to the support device. During breaks, worker 7 leans back, resting their buttocks against the inflated inflatable support body 2, using its support to achieve a seated rest. During rest, the body fixation components maintain the relative fixation between the inflatable support body 2 and the worker. Connect the inflation component to the air passage interface 9 of the inflatable support body 2. The air passage interface 9 is used to provide an inflation channel and serve as the connection interface of the inflation component. Start the inflation component to inflate the inflatable support body 2 with gas. The inflation component is used to inflate the inflatable support body 2 until the inflatable support body 2 expands to a state with supporting strength. Disconnect the inflation component from the air passage interface 9 and close the air plug at the air passage interface 9. The air plug is used to seal the air passage and prevent gas leakage inside the inflatable support body 2. Finally, the inflatable support body 2 forms a stable support structure to provide body support for the workers.

[0040] This invention utilizes the flexible, sealed structure of the inflatable support body 2. Gas is injected into its interior using an inflation component, causing the originally foldable and retractable flexible body to expand and form a support structure with a certain rigidity and support strength. The air passage interface 9 serves as the inflation channel and connection interface, working with an air plug to achieve sealing and pressure retention after inflation, ensuring the inflatable support body 2 maintains a stable inflated state. Multiple sets of human fixation components secure the inflated support body to the worker's body: the upper fixation component connects to the torso, and the lower fixation component connects to the lower limbs. The binding force of the human fixation components prevents relative displacement between the inflatable support body 2 and the worker's body. The inflated inflatable support body 2 forms a reliable support surface below the waist and abdomen and in front of the thighs, distributing local pressure on the worker's body, assisting in maintaining body posture, reducing the load on the waist and leg muscles during work, and achieving effective support for the worker, while also being portable and flexible in use.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
