Claims
- 1. A window propelling system, the system comprising:
- a cylinder assembly having a piston movably disposed therein;
- a forced fluid source connected to the cylinder assembly;
- a piston cable in communication with the piston, wherein the piston cable extends from the cylinder assembly;
- a lift cable having first and second ends for attachment at opposite sides of a window;
- a lift pulley assembly connected to the piston cable and supporting the lift cable, the lift pulley assembly transposing a force placed on the piston cable into a force on both ends of the lift cable to open the window to which the lift cable is attached; and
- a guide assembly for opening a lock on the window to which the lift cable is attached, the guide assembly comprising:
- a frame receiving an end of the lift cable;
- a slide block selectively disposed within the frame, wherein the side block is attached to an end of the lift cable and is configured to lock within the frame;
- a window unlock cable attached to an end of the slide block, opposite the lift cable; and
- a pulley disposed within the slide block assembly directing the window unlock cable to the lock.
- 2. A window propelling system, a window, the system comprising:
- a cylinder assembly having a piston movably disposed therein;
- a forced fluid source connected to the cylinder assembly;
- a piston cable in communication with the piston, wherein the piston cable extends from the cylinder assembly, the piston including a central passage selectively receiving the piston cable;
- a lift cable having first and second ends for attachment at opposite sides of a window;
- a lift pulley assembly connected to the piston cable and supporting the cable for transposing a force placed on the piston cable into a lifting force on both ends of the lift cable for opening the window to which the lift cable is attached; and
- a takeup pulley assembly in communication with the piston cable opposite the lift pulley assembly to tension the piston cable as the window to which the lift cable is attached is opened.
- 3. The window propelling system of claim 2 further comprising:
- a takeup cable attached to the piston cable, wherein the takeup cable extends from the cylinder assembly opposite the piston cable to the takeup pulley assembly; and
- a crimp seal attaching the piston cable to the takeup cable, wherein the crimp seal has a diameter larger than a diameter of the central passage of the piston for sealing the central passage of the piston.
- 4. The window propelling system of claim 3 wherein the piston cable is loosely coupled to the piston so that the piston cable is moveable to permit manual opening of the window to which the lift cable is attached and the crimp seal seals the piston cable when the force fluid source is operated.
- 5. The window propelling system of claim 2 wherein the takeup pulley assembly includes:
- a fixed pulley block;
- a free pulley block in communication with the fixed pulley block; and
- a takeup spring attached to the free pulley block, wherein the takeup pulley is disposed about the fixed pulley block and the free pulley block, and further wherein the takeup spring tensions the free pulley block away from the fixed pulley block to prevent slack in the piston cable as the window to which the lift cable is attached is opened.
- 6. The window propelling system of claim 2 wherein the lift pulley assembly includes an equalizer pulley connected to the piston cable for equalizing the lifting force at both ends of the lift cable.
- 7. A window propelling system, the system comprising:
- a cylinder assembly having a piston movably disposed therein;
- a forced fluid source connected to the cylinder assembly;
- a piston cable in communication with the piston, wherein the piston cable extends from the cylinder assembly;
- a lift cable having first and second ends for attachment opposite sides of a window; and
- a lift pulley assembly connected to the piston cable and supporting the lift cable for transposing a force placed on the piston cable into a lifting force on both ends of the lift cable for opening the window to which the lift cable is attached; and
- a firing assembly controlling supply of forced fluid from the forced fluid source to the cylinder assembly.
- 8. The window propelling system of claim 1, wherein the firing assembly comprises:
- a lever arm for receiving a firing signal from a user;
- a puncture pin associated with the lever arm;
- a supply block for maintaining the forced fluid source and for guiding the puncture pin, wherein the supply block includes a port for directing fluid from the forced fluid source to the cylinder assembly;
- a motivator positioned between the lever arm and the supply block for biasing the lever arm toward the forced fluid source; and
- a puncture indicator associated with the puncture pin for indicating release of fluid from the forced fluid source.
- 9. The window propelling system of claim 8, wherein the puncture indicator is attached to the lever arm.
- 10. The window propelling system of claim 8, wherein the motivator is a spring.
- 11. The window propelling system of claim 8 further comprising a hammer assembly for generating the firing signal.
- 12. The window propelling system of claim 11, wherein the hammer assembly comprises:
- a fixed directional block;
- a hammer shaft, having a cocking end, a retaining portion and a tip, movably disposed within the directional block;
- a spring maintained along the hammer shaft such that the spring is compressed between the retaining portion and the directional block;
- a pawl in communication with the hammer shaft, wherein the pawl is attached to a trigger for receiving the firing signal from a user; and
- a lanyard attached to the cocking end of the hammer shaft for directing the hammer shaft into a cocked position with respect to the firing assembly.
- 13. The window propelling system of claim 7 further comprising:
- a secondary trigger assembly for releasing the firing assembly, wherein the secondary trigger assembly is configured to signal the firing assembly upon sensing an emergency.
- 14. The window propelling system of claim 13 wherein the secondary trigger assembly comprises:
- a crank member having a first and second end;
- a motivator biasing a first end of the crank member in response to a signal from a user;
- a pin connected to the second end of the crank member;
- a heat sensor communicating with the pin, wherein the heat sensor alters position of the pin in response to reaching a particular temperature; and
- a trigger cable connected between the second end of the crank member and the firing assembly, wherein the trigger cable is configured to release the firing assembly in response to movement of the crank member.
