Technical Field

[0001] The invention relates to the field of shoes, in particular to an improved air bag life-saving shoe. Background Art

[0002] Shoes are an indispensable item in people's lives. People use shoes to protect their feet from external injuries. With the improvement of people's living standards, people are no longer satisfied with traditional functions such as wearing comfortably, but hope that shoes can have more functions.

[0003] Most shoes on the market do not have the function of lifesaving when falling into water. A few lifesaving shoes with buoyancy airbags have the problem that the airbags are arranged at the heels. When the airbags are inflated, they are located at the back of the human body and are not easy for the drowning person to grasp. This has a poor lifesaving effect.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned defects in the prior art, which resulted in the present case. Summary of the invention

[0005] The main purpose of the present invention is to provide an improved air bag life-saving shoe, which has the characteristics of good life-saving effect and is convenient for people who fall into the water to grab.

[0006] In order to achieve the above object, the solution of the present invention is:

[0007] An improved air bag life-saving shoe, comprising a sole and an upper connected to the sole, wherein an air tank and a trigger switch are arranged in the sole, and the air tank and the trigger switch are arranged in the sole at the corresponding heel; a cover portion is formed on the upper at the instep, and the cover portion is connected to the upper through an easy-to-open point breaking line, and a main air bag is arranged on the inner side of the cover portion, and the main air bag is connected to the air tank through a first pipe and a trigger switch; a neck connection portion is formed at the connection of the main air bag close to the upper, and the main air bag is fixedly connected to the first pipe on the sole through the neck connection portion.

[0008] Furthermore, the main airbag is provided with an embracing hole for the arm to pass through, and the embracing hole is arranged through the center of the upper part of the main airbag.

[0009] Furthermore, a handle is provided on the upper portion of the main airbag.

[0010] Furthermore, the trigger switch is a button switch, and the button switch is exposed outside the sole through an opening on the side of the sole.

[0011] Furthermore, the trigger switch is a pressure switch, and a receiving hole connected to the outside is provided on the side of the sole. The pressure switch is located in the receiving hole, and the triggering threshold of the pressure switch is the water pressure at a depth of 1 meter.

[0012] Furthermore, an annular airbag is provided at the ankle opening of the shoe upper, and the annular airbag is connected to a main airbag; the annular airbag is provided on the outer side of the shoe upper at the ankle opening; the annular airbag is connected to the main airbag through a second pipe; and the annular airbag can be placed on the thigh of a person who falls into the water after being inflated.

[0013] Furthermore, an annular limiting groove is formed on the outer side of the shoe upper at the ankle opening, and the annular airbag is fixedly arranged in the annular limiting groove.

[0014] Furthermore, the main airbag is connected to the first pipe on the sole through a connecting assembly, and the connecting assembly includes an air inlet nozzle, a one-way valve and a connecting seat. The air inlet nozzle is fixedly arranged on the main airbag, and a one-way valve is arranged inside the air inlet nozzle; the connecting seat is fixedly connected to one end of the first pipe close to the main airbag, and the main airbag is detachably connected to the connecting seat through the air inlet nozzle.

[0031] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0032] like Figures 1 to 5 As shown, it is an improved air bag life-saving shoe involved in the present invention, comprising a sole 1 and an upper 2 connected to the sole 1, wherein an air tank 11 and a trigger switch 12 are arranged in the sole 1, and the air tank 11 and the trigger switch 12 are arranged in the sole 1 at the corresponding heel; a cover portion 21 is formed on the upper 2 at the instep, and the cover portion 21 is connected to the upper 2 through an easy-to-open point breaking line 211, and a main air bag 22 is arranged on the inner side of the cover portion 21, and the main air bag 22 is connected to the air tank 11 through a first pipe 13 and the trigger switch 12; a neck connection portion 221 is formed at the connection of the main air bag 22 close to the upper 2, and the main air bag 22 is fixedly connected to the first pipe 13 on the sole 1 through the neck connection portion 221.

[0033] Thus, the improved airbag lifesaving shoe of the present invention is that when the user falls into the water, the trigger switch 12 turns on the gas tank 11 to quickly inflate the main airbag 22, the volume of the main airbag 22 increases, and the buoyancy generated by the main airbag 22 in the water is greater than the gravity of the person who falls into the water. The inflated main airbag 22 breaks the easy-opening point break line 211 of the cover part, and because the main airbag 22 is arranged at the position of the upper 2 corresponding to the instep, the main airbag 22 is formed on the front side of the body of the person who falls into the water, which is convenient for the person who falls into the water to grab.

[0034] The air tank 11 is arranged at the position of the sole 1 corresponding to the heel, making full use of the thickness of the sole 1 at the heel, and reducing the thickness of the sole 1 that needs to be increased due to the arrangement of the air tank 11. By arranging the neck connection part 221, when the main air bag 22 is inflated, the main air bag 22 can be conveniently swung so that the drowning person can grasp the main air bag 22. The cover part 21 has the effect of covering the main air bag 22. When the main air bag 22 is inflated, the easy-open point breaking line 211 is disconnected due to the expansion of the main air bag 22, and the main air bag 22 is fully released. When the main air bag 22 is not inflated, the main air bag 22 is not visible from the outside due to the arrangement of the cover part 21, thereby maintaining the integrity of the upper 2.

[0035] Preferably, the main airbag 22 is provided with an embracing hole 222 for the arm to pass through, and the embracing hole 222 is arranged through the center of the upper part of the main airbag 22. The arm of the drowning person passes through the embracing hole 222, so that the main airbag 22 can be embraced in front of the drowning person. The formation of the embracing hole 222 in the main airbag 22 is similar to the formation of the center hole of a life buoy, and will not affect the normal inflation of the main airbag 22.

[0036] Preferably, a handle 223 is provided on the upper portion of the main airbag 22. The handle 223 serves to facilitate the gripping of the hands of the drowning person.

[0037] Preferably, the trigger switch 12 is a button switch, and the button switch is exposed outside the sole 1 through an opening on the side of the sole 1. After the user falls into the water, the gas tank 11 is triggered to quickly supply gas by pressing the button switch.

[0038] Preferably, the trigger switch 12 is a pressure switch, and a receiving hole communicating with the outside is provided on the side of the sole 1, the pressure switch is located in the receiving hole, and the triggering threshold of the pressure switch is the water pressure at a depth of 1 meter. In this way, when the user falls into water deeper than 1 meter, the water pressure acts on the pressure switch through the receiving hole, thereby triggering the pressure switch to enable the gas tank 11 to quickly supply gas.

[0039] Preferably, an annular airbag 3 is provided at the ankle opening of the upper 2, and the annular airbag 3 is connected to the main airbag 22; the annular airbag 3 is provided on the outer side of the upper 2 at the ankle opening; the annular airbag 3 is connected to the main airbag 22 through a second pipe 31; the annular airbag 3 can be set on the thigh of the drowning person after being inflated. The gas in the main airbag 22 enters the annular airbag 3 through the pipe, and when the annular airbag 3 is inflated, the inner and outer circles of the annular airbag 3 expand outward at the same time, and the diameter of the inner circle increases until it exceeds the thigh; with the expansion of the main airbag 22 and the annular airbag 3, the annular airbag 3 slides upward from the ankle to the groin of the thigh, and the annular airbags 3 of the two shoes correspond to the two sides of the thigh of the drowning person respectively, and the main airbag 22 pulls the annular airbag 3 upward, and the annular airbag 3 pulls the drowning person upward to form a stable state.

[0040] Preferably, an annular limiting groove 23 is formed on the outer side of the upper 2 at the ankle opening, and the annular airbag 3 is fixedly arranged in the annular limiting groove 23. The annular limiting groove 23 provides a placement space for the annular airbag 3, and the annular airbag 3 is limited in the annular limiting groove 23 during normal use.

[0041] Preferably, the main airbag 22 is connected to the first pipe 13 on the sole 1 through a connecting component 4, and the connecting component 4 includes an air inlet nozzle 41, a one-way valve 42 and a connecting seat 43. The air inlet nozzle 41 is fixedly arranged on the main airbag 22, and a one-way valve 42 is arranged inside the air inlet nozzle 41; the connecting seat 43 is fixedly connected to one end of the first pipe 13 close to the main airbag 22, and the main airbag 22 is detachably connected to the connecting seat 43 through the air inlet nozzle 41.

[0042] When the gas tank 11 is inflated, the gas enters the main airbag 22 through the air inlet nozzle 41 and the one-way valve 42 in the air inlet nozzle 41. When the inflation is completed, the main airbag 22 together with the air inlet nozzle 41 can be removed from the connecting seat 43, and the drowning person can hold the main airbag 22 for lifesaving.

[0043] Preferably, an inner layer 24 is formed on the upper 2 inside the cover surface 21, and the main air bag 22 is arranged between the cover surface 21 and the inner layer 24. The inner layer 24 serves to isolate the main air bag 22 from the user's instep. In this way, when the main air bag 22 expands, the impact on the instep is relatively small, and the sole of the foot can be effectively prevented from being exposed outside the upper 2 along the air bag.

[0044] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
