摘要:
An inflation device mechanism (10) for inflation of an inflatable article comprises a housing (11) for supporting a container (18) of pressurized fluid and a piercing device (16) displaceable from a retracted position to penetrate the container to release pressurized fluid, bias means (22) to move the piercing device to penetrate the container, and actuation means comprising co-operating latching elements (26, 30) which, in an engaged, latched configuration, retain the piercing device retracted, said actuation means being actuable by either a first (35) or a second (36) control member to allow the latching elements to disengage and permit the piercing device to penetrate the container under action of the bias means, the first control member (35) comprising a water sensitive member which surrounds the latching elements and has a strength sufficient normally to support the latching elements in the engaged configuration but to allow the elements to disengage when reduced in strength by exposure to water, and the second control member (36) comprising a member which surrounds the co-operating elements and is removable manually (38) whereby the latching elements are free to disengage.
摘要:
An inflator used for inflation of an object such as life jackets, life boats, etc is revealed. A needle-shaped shaft is driven by a transmission arm to pierce a seal of a gas cylinder on the inflator. Thus compressed gas in the gas cylinder is released and flowing through the inflator to inflate the object. The needle-shaped shaft is arranged with two color areas for representing state of the inflator. The color area is displayed through windows of the inflator to show the state now. The inflator features on simple structure, convenience in use, reduced cost and precise movement.

A device for increasing the buoyancy of a human body in water includes an inflatable tube member (1), a coupling unit (4) including a first part (8) and a second part (11), the coupling unit together with the tube member being arranged to form an endless float ring when the device is in the active state, a gas cartridge (6) having a punctureable membrane, a penetration element (23) arranged to puncture the membrane, a gas duct extending between the first part of the coupling unit and the tube member, wherein the gas cartridge and the penetration element are mutually displaceable in the direction towards each other. A first coupling member (20) of the first part is pivotally arranged about a pivot between an inactive position and an actuating position, in which the first coupling member, direct or indirect, causing the mutual displacement of the gas cartridge and the penetration element.
摘要:
Disclosed is an inflator assembly. The assembly operates by puncturing a diaphragm of an associated container to thereby releasing a volume of pressurized gas. The pressurized gas, in turn, is used to inflate an article, such as a life raft. The inflator assembly is adapted to be either manually or automatically actuated. The various details of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.

An inflation device 10 for an inflatable article comprises a housing 11 for supporting a container 15 of pressurised fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurised fluid, said container being contained within a protected casing 20 which is secured non-releasably to the housing thereby to prevent removal of the pressurised container.
摘要:
A manual inflator having a status indicator that indicates whether a fully-charged, unspent gas cylinder has been installed on the inflator. The status indicator comprises a “single point” indicator having an indicator window that displays the color “green” when the automatic inflator is fully operational or the color “red” when the inflator is at least partially inoperable automatically due to the removal of the gas cylinder or due to the firing of the inflator resulting in a spent gas cylinder.
摘要:
There is provided an inflatable safety apparatus (10, 10′) which is manually or automatically operated having a compressed gas bottle (17, 20) with an operation rod (25, 54) in combination with an inflatable element (15, 18) which is initially folded upon itself as an open ring and housed in a ribbon-shaped case (13, 26) secured to the user's waist. The inflatable element (15, 18) is connected to the ribbon-shaped case (13, 26) by extensible tapes (27, 60) or ducts (14, 14′, 16, 16′) whose extension allows positioning the inflatable element at the height of the user's armpit.
摘要:
A trigger device enabling a larger actuating force to be restrained by a smaller control force comprises a housing in which is rotatably mounted a primary lever biased to rotate from a cocked position to a firing position by a tension spring. The tension spring is located such that the rotational bias to the primary lever is significantly greater in the firing position than in the cocked position. The trigger device is typically used for both automatic and manual release of compressed gas from a bottle to an inflatable life-saving aid by way of a piercing pin moved by a cam surface on a secondary lever which can be manually rotated by a toggle or automatically by the primary lever on the dissolving of a water-soluble tablet restraining the primary lever in the cocked position.
摘要:
The present invention relates to improved personal flotation devices and their methods of use. Advantageously, the devices and methods of the invention eliminate the need for a pyrotechnical firing mechanism, and compared to current devices, are less apt to be spontaneously activated by deterioration that is caused by storage in a humid environment or the passage of time. Instead, the devices and methods of use of the present invention incorporate electronic circuitry to activate automatic operation.
摘要:
An inflation device is provided including a shell, a pin, a restraining element, and a barrier. The shell may be coupled to an inflation canister. The pin is positioned within the shell in order to open a seal of the inflation canister. The restraining element is positioned within the shell and is positioned to prevent the pin from opening the seal of the inflation canister. The restraining element is dissolvable. The barrier is positioned within the shell. The barrier includes a fluid resistant skin and a heating element coupled to the fluid resistant skin. The heating element may open a portion of the barrier responsive to an electrical current running through the heating element.
