Life-saving Bracelet

Abstract

A life-saving bracelet includes a ring body being able to be tightened to a user's arm, a casing connected to the ring body, an air bag folded inside the casing, an air cylinder disposed inside the casing, a control valve connected between the air bag and the air cylinder, and a protective cover pivotally disposed on the casing. When the protective cover pivotally rotates to an open position, the control button of the control valve exposes to the outside. After the control button is pressed, the control valve communicates the air bag and the air cylinder, and the air in the air cylinder immediately inflates the air bag. The air bag expands to break the casing and extends to outside. Thus, the life-saving bracelet is convenient to carry, easy to use, and not affecting the agility of the user when doing water activities.

DETAILED DESCRIPTION

[0023] Referring to FIGS. 1-7, a preferred embodiment of the life-saving bracelet 100 includes a ring body 10, a casing 20, an air bag 30, an air cylinder 40, a control valve 50, and a protective cover 60.

[0024] Referring to FIGS. 1-3, the ring body 10 is connected to the casing 20. The ring body 10 can be a hard or a flexible material for being fastened to the user's body, such as wrist or arm. The material can be a braid or a plastic band. In the present embodiment, the ring body 10 has a strip 11, a first connecting portion 12 at an end of a front side of the strip 11, and a second connecting portion 13 at another end of a back side of the strip 11. The first connecting portion 12 is the fabric hook surface of the Velcro, and the second connecting portion 13 is the loop fastener. The first connecting portion 12 and the second connecting portion 13 can repeatedly attach or detach to each other.

[0025] Moreover, the first connecting portion 12 and the second connecting portion 13 can also be other types of buckling device. Besides, the ring body 10 (or strip 11) can also be two strips 11. On end of each of the two strips 11 is attached to the casing 20, and another end of each of the two strips 11 is connected or detached by the Velcro or other buckle equipment. (not shown in the FIG.)

[0026] Referring to FIGS. 1-3, the casing 20 can accommodate other aforementioned elements. The casing 20 connects to one side of the ring body 10. In the present embodiment, the casing 20 is connected to the outer middle segment of the strip 11 of the ring body 10. A part of the casing 20, such as an outer side surface, is covered by a cover 21. The cover 21 can be broken or opened by a predetermined pressure. Therefore, the material of the cover 21 can be glass or plastic which is easy to break, so that the cover 21 can break when being under pressure. Moreover, the cover 21 can also be positioned on the casing 20 by latching. The cover 21 can be pressed to open due to the elasticity of the plastic cover 21 (not shown in the FIG.). Besides, one side of the casing 20 is formed with a through hole 22 communicating inside and outside of the casing 20.

[0027] Referring to FIGS. 1-3, the air bag 30 can accommodate air, and the air bag 30 is folded and stored inside the casing 20. The air bag 30 can be inflated by air.

[0028] Referring to FIGS. 1-3, the air cylinder 40 is stored with compressed air, such as air, nitrogen, or other inert gas. The air cylinder 40 is fixed inside the casing 20 and is able to release the air or gas under control by the user.

[0029] Referring to FIGS. 1-3, the control valve 50 is connected between the air bag 30 and the air cylinder 40. The control valve 50 has a control button 51 extending outside of the through hole 22 of the casing 20. The control button 51 can be a button or a knob. When the control button 51 is not under outer force, the control valve 50 stops the communication of the air bag 30 and the air cylinder 40. When the control button 51 is under outer force or being pressed by the user, the control valve 50 will be opened to communicate the air bag 30 and the air cylinder 40, so as to release the gas or air in the air cylinder 40 to the air bag 30.

[0030] Referring to FIGS. 1-3, the protective cover 60 is pivotally installed on the casing 20 and being able to reciprocally and pivotally rotate between the open position and the protective position. When the protective cover 60 is in the protective position, the protective cover 60 covers the control button 51 of the control valve 50 to prevent outer force from pushing the control button 51. When the protective cover 60 is in the open position, the control button 51 can be exposed to outside to allow outer force pushing the control button 51.

[0031] Therefore, the aforementioned is the detail structure and the assembling method of the preferred embodiment of a life-saving bracelet 100. The feature of using is illustrated as follows:

[0032] First, when the user swims or does other water activities, the user can fasten the ring body 10 on the arm, which is wrapping the strip 11 around the arm and then attaching or buckling the first connecting portion 12 to the second connecting portion 13 so that the ring body 10 can be fixed to the arm, and thus completing the wearing process of the preferred embodiment of the present invention.

[0033] And then, when the user goes into spasm, lacks physical strength, or is under other accident, such as falling into water, the user can switch the protective cover 60 to the open position as soon as possible, and press the control button 51 of the control valve 50 to release the air in the air cylinder 40 to the air bag 30 immediately. Thus, the air bag 30 will be inflated to break or open the cover 21 of the casing 20 to further extend out of the casing 20 (as shown in FIGS. 4-6), and the user can float on the water surface (as shown in FIG. 7) by the air in the air bag 30. As such, the drowning can be prevented, and the user can also have more time to recover the physical strength, as well as prolonging the time to wait for rescue.

[0034] The embodiment shown in FIG. 7 only demonstrates wearing one life-saving bracelet 100. The user can also wear two life-saving bracelets 100 on both arms, which makes the user feel more comfortable and is safer as well.

[0035] The life-saving bracelet 100 of the preferred embodiment of the present invention is light weighted and thus is very easy to carry for the people doing water activities. Moreover, since the air bag 30 is folded and stored inside the casing 20 before being inflated, the life-saving bracelet 100 will not influence the agility of the user when doing water activities, which is very convenient for boat traveling or working

[0036] Besides, the life-saving bracelet 100 of the preferred embodiment of the present invention is further provided with a global positioning system module (GPS module) 70, which facilitates the person falling into the water to be quickly rescued. The GPS module 70 is a conventional technique, and thus not described hereinafter.

[0037] Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
