Abstract
An inflatable water flotation device for remote rescue of a victim in peril of drowning. The device has one or more elongate, closed tubular members constructed of a flexible, air-impervious material permitting compact folding and storage of the device in a deflated configuration. Elongate tubular members are stored in a compact, water-tight case. Upon inflation by a gas, the tubular members are deployable as a unit to an elongate, generally linear, semi-rigid device, one end of which is remotely maneuverable to a distant victim. A self-contained gas supply associated with the device is operable for rapid inflation of the tubular members at time of emergency. A safety line is contiguous with the length of the device and facilitates grasping by the victim to expedite recovery of the victim.
Claims22
A safety device to enable a rescuer person to lend assistance to a remote imperiled victim comprising:
- elongate tubular means inflatable to form a substantially linear semi-rigid elongate, floatable unit having a first end that, when inflated, can be maneuvered toward an imperiled victim, and a second end that can be manipulated by a rescuer person for maneuvering the first end, and deflatable for folding into a compact bundle, said tubular means having at least a first tubular member and a second tubular member, and means having a restricted orifice connecting the first tubular member with the second tubular member to allow gas to flow from the first tubular member to the second tubular member to inflate the second tubular member after the first tubular member has been inflated and elongated by gas, gas supply means for storing a supply of gas, and releasable valve means connecting the gas supply means with the first tubular member and operable for selective rapid release of gas from the gas supply means to the first tubular member, said means having a restricted orifice defining an orifice of a size to restrict flow of gas from the first tubular member to the second tubular member such that rapid release of gas from the gas supply means first inflates the first tubular member to a semi-rigid elongate shape and then inflates the second tubular member.
A safety device comprising:
- elongate tubular means inflatable to form a substantially linear semi-rigid elongate, floatable unit, and deflatable for folding into a compact bundle, said tubular means having a first tubular member, a second tubular member, and a third tubular member, and means having a restricted orifice connecting the first tubular member with the second tubular member to allow gas to flow from the first tubular member to the second tubular member to inflate the second tubular member after the first tubular member has been inflated, said third tubular member located adjacent the second tubular member, said first tubular member being connected to the third tubular member to allow gas to flow from the first tubular member to the third tubular member to inflate the third tubular member after the first tubular member has been inflated and elongated by gas, said first, second and third tubular members when inflated and elongated, being arranged in a triangular pattern with each member having a portion in engagement with each other, gas supply means for storing a supply of gas, and releasable valve means connecting the gas supply means with the first tubular member and operable for selective release of gas from the gas supply means to the first tubular member for first inflating the first tubular member to a semi-rigid elongate shape and then inflating the second and third tubular members.
A safety device to enable remote rescue of an imperiled victim comprising:
- elongate tubular means inflatable to form a substantially linear semi-rigid elongate floatable unit having a first end that, when inflated, can be maneuvered toward an imperiled victim, and a second end that can be manipulated by a rescuer person for maneuvering the first end, said tubular means being deflatable for folding into a compact bundle, said tubular means having a plurality of elongatable tubular members, cover means surrounding said tubular members, gas supply means for storing a supply of gas, releasable valve means for selective rapid release of gas from the gas supply means to a first of the tubular members for inflating said tubular members to form a semi-rigid elongated shape and means interconnecting the first tubular member with the other tubular members and restricting flow of gas from the first tubular member to the other tubular members such that upon release of gas from the gas supply means, the first tubular member is rapidly inflated and then the remaining tubular members are inflated.
