  • Patent number: 7004287
    Abstract: An improved safety ladder and safety window as well as a method for use are disclosed. The ladder is discrete and compact, for convenience. The ladder is stored in a hidden container that is an extension or an addition to a normal window, or made part of an existing window, for example by being housed in a box associated with the window. The inventive built-in safety ladder provides for an easy escape in the case of an emergency. The window may be employed in a double-hung window, casement window, awning, hopper, or any operating window which can be used for egress. The fire escape can be incorporated in wood, vinyl, aluminum, steel, and other types of windows. The box may also be used for housing other items such as emergency escape smoke hoods that are used as breathing apparatus, or as a hidden wall safe to store valuables and can be accessed using a security code.

  • Patent number: 6102155
    Abstract: An emergency escape system (16) for a window (13) of a building (10) includes an escape ladder (36) stored within a window frame (21). A sill part (23) covers a recess (32) containing the escape ladder and allows a window part (22) to form a normal seal with the sill as if no escape ladder system were present. In an emergency, the escape ladder can be quickly deployed to allow a person to exit the building safely through the window. Spacers (88) can be used to provide a more stable escape ladder. A removable cartridge (81) can also be used to easily replace the escape ladder system after the escape ladder has been used or damaged.

  • Patent number: 5893431
    Abstract: A basement emergency exit assembly has a ladder for exiting from a basement window. The window is held within tracks mounted at the interior of the window frame. By moving the bottom of the ladder away from the wall, the window is permitted to slide down the track out of its frame and the ladder is positioned at an angle for easy egress. The window can either fall directly into a pocket within a wall, or, the tracks can be swung out as the ladder is moved thereby pulling the window out of frame and causing it to slide along the tracks until it is clear of the window opening.

  • Patent number: 5785147
    Abstract: The subject invention relates to a type of escape ladder structural improvement (1), comprising a housing, an inside ladder, an outside ladder, an outside cover and a gear transmission; the hollow interior of the housing comprising an escape channel; the inside ladder, the outside ladder and the outside cover being respectively installed on the rear and front openings of the hollow interior in the housing; said inside ladder can swing backwards to extend itself by way of its own gravitational weight when a handle is pulled, and via the gear transmission mechanism, it in turn drives the outside cover and the outside ladder to swing forwards to extend themselves, so that the escapee will be able to climb the inside ladder, to the hollow interior of the housing, then to the outside ladder, and escape from the scene by means of the escape device on the outside cover; said mechanism will enable easy operation to create a best escape channel without causing bad effects on the appearance of a building.

  • Patent number: 4237654
    Abstract: A fire escape window system has a fixed outer, peripheral frame set permanently into a window opening of a wall. An inner frame carrying sash units, screens, storm glass, and the like is mounted in the outer frame on a hinge axis. The inner frame pivots from a position weather-sealed across the outer frame to an open position where the opening in the outer frame is unobstructed for emergency personal egress. A latch retains the inner frame in a closed, sealed position but is quickly releasable for swinging of the inner frame to the open position. A spring may be used to bias the inner frame to move automatically to the open position upon release of the latch. A safety alarm signals upon opening of the inner frame. The latch may be electrically operated and, if so, it may be connected for opening the inner frame selectively in conjunction with a smoke or other fire detector which is activated by an emergency condition.

  • Patent number: 4164990
    Abstract: An apparatus for evacuating passengers from a passenger-carrying cabin having a floor suspended above the ground comprises upper and lower plates engageable over the upper and lower sides of a vertical hole through the floor. These plates are both secured tightly in place on the respective sides of the floor in a normal position and are released in an emergency position, with the lower plate dropping away from the car. A tubular life-saving chute is secured to the floor between the sides in the hole and is folded up between the plates in the normal position, but extends from the floor toward the ground in the emergency position to allow persons to be saved to slide down through this chute. A linkage normally rigidly interconnects the two plates together, but is operated in case of fire or the like to disconnect them.
