Definitions

  • the invention relates to a novel method and device for providing a rescue parachute capable of fully deploying prior to the user diving off elevated locations and for allowing a safe parachutist jumping from any altitude.
  • Parachutes have been used for years by parachutists for safely diving off airplanes. Occasionally stuntmen and daredevils attempt diving off very high structures, such as bridges dams, or skyscrapers. Many parachutes are designed with round or square canopies, which when deployed slow down the user's free fall, thus facilitating safe landing on the ground.
  • a typical sky-diving or an airplane parachute is tucked away inside a bag worn by the parachutist and is deployed when the activating string is pulled, opening the bag and causing the parachute to deploy.
  • the response time of such a parachute is in the order of a few seconds, and requires initial high-velocity for successful deployment, which is good enough for sky-divers, but may prove fatal for persons diving off tall buildings.
  • Both air-balloon sections are filled with lighter-than-air gas and thus provide an active lift to the parachute.
  • the sections are filled either manually, in accordance with a predetermined scheme, by the parachutist himself or automatically after the main canopy opens up.
  • the characteristics of this device inter-alia the arrangement of the inflatable member in sections as well as the manual inflation option, suggest that the device is not designed for rapid fully deployment prior to the user diving off elevated locations. It is an object of the present invention to provide a rescue parachute device and method including a rapid deploying mechanism for fully deploying the canopy prior to a hasty escape from any elevated location or building. Another object of the present invention is to provide such rescue parachute device that provides stability to the parachutist during the inflation procedure of the parachute.
  • Another object of the present invention is to provide such rescue parachute device that is comfortable to wear and adjust and is easily handled.
  • Another object of the present invention is to provide such parachute device that by being able to deploy before jumping, can be used as a safer alternative for the sport of jumping of tall structures (known as BASE jumping).

  • a stabilizer support is provided, for enhanced stability of the user during inflation of the canopy.
  • the stabilizer support comprises a foldable support frame.
  • the pressurized gas comprises gas that is lighter than air.
  • the pressurized gas comprises helium.
  • the harness comprises straps for accoutering the device around the waist and under the legs of the user.
  • the piping comprises pipes provided on two opposing sides of the housing, so as to facilitate balanced symmetric deployment of the inflatable canopy.
  • more than one pipe is provided on either of the two opposite sides.
  • the piping is aligned with a direction in which the canopy is deployed when inflated.
  • strings are provided to hold the canopy in a desired position.
  • the strings are connected to a bar held by strings to the harness.
  • the strings are connected to a bar held by strings to the housing.
  • the housing is coupled to the harness at a position, which is over the head of the user.

  • the sleeves and the canopy are made from a flexible impervious and impermeable material.

  • Yet another aspect of the present invention is the provision of a rescue parachute device that allows the user to dive off any elevation, since the parachute deploys prior to the jump, eliminating the need for minimal deployment altitude .
  • the novel rescue parachute device of the present invention comprises a main inflatable canopy, a gas tank filled with pressurized gas (lighter than air to hold the inflated canopy above the jumper prior to jump) for inflating the parachute, inflation tubes connected to the inflatable canopy, a housing for housing the inflatable canopy in its deflated state and means for accoutering the device to the user's body.

  • the inert force of the pressurized gas is efficiently utilized for fast and appropriate inflation of the canopy by installing the sleeves of the inflatable canopy over the inflating pipes, preferably aligning the inflatable canopy with the inflating pipes.
  • the stabilizer frame 18 not only serves for support but also causes the user to bend over the sill into a desired position, preferably defining about 45 degrees between his back and the wall, allowing the canopy to deploy outside the window, preventing deployment inside the room, which might lead to the user being captured inside and unable to rescue himself.

  • the flexible air sleeves 30, as well as the inflatable canopy itself are preferably made of a gas impermeable material, for example durable plastic nylon or polymer. Positioning the parachutist in the optimal bending position, as proposed, is provided to absorb the blast and resisting forces, which result from the expansion of the helium gas and the inflation of the canopy.
  • the parachutist climbs over the window and pushes off the wall, straightening himself up from his bending position and descending to safety.
  • the inflating pipes are preferably aligned with the direction in which the inflatable canopy deploys, as this is important for fast deployment of the parachute. This maximizes efficiently the thrust provided by the errupting gas from the canister (and pyrotechnic means if these are used) to deploy the canopy in the right position over the user's head.
  • the lift forces of the lighter-than-air gas facilitate prolonged suspension of the canopy over the user before he dives off.
  • the rescue parachute device of the present invention can be used at any elevation, since it is fully deployed prior to diving.
