Abstract

Safety apparatus for lowering one or more persons from a window or a hotel room or the like characterized by structural framework that is affixed inside the room and disposed adjacent the window, an extensible arm that is pivotally connected with the structural framework and having a free end that is pivotally moveable exteriorly of the window, a rotating drum having a lineal member disposed thereabout and connected therewith for controllably dispensing the member and any person at the end of the lineal member, sheaves suitably mounted with the lineal member traversing thereover, body harness means for holding the person or persons and connected with the lineal member, such as the cable, and means for controlling the rate of descent of the person without requiring a separate control cable, radio control with elaborate receiving equipment inside the room or the like.

Claims

1. Safety window apparatus for lowering at least one person from a window of a hotel room or the like comprising:

a. structural framework disposed and affixed interiorly of the room and disposed adjacent the window;

b. extensible arm pivotally connected at its first end with said structural framework and having a free end that is pivotally moveable exteriorly of said window;

c. rotatable drum journalled in said structural framework for rotating and controllably playing out a lineal member for lowering the person;

d. lineal member disposed about and connected with said rotatable drum means;

e. at least one sheave mounted at the free end of said arm and having said lineal member traversing thereover;

f. body harness means for holding said person, said body harness means being connected with said lineal member; and

g. means controlling the rate of rotation of said rotatable drum means and hence the rate of descent of said person;

said means controlling the rate of rotation comprising a brake means;

said arm having a brake applying means for applying a braking force proportional to the weight of said at least one person being lowered by said lineal member from the end of said arm.

2. The safety apparatus of claim 1 wherein said apparatus is stored within a cabinet lower than said window and said structural framework includes an upwardly extensible means for raising said arm above the bottom of said window for extending said arm exteriorly of said room.

3. The safety apparatus of claim 2 wherein said rotatable drum is disposed adjacent the floor in said room and a second sheave is disposed adjacent the top of said extensible means;

said second sheave having said lineal member traversing thereover.

4. The safety apparatus of claim 1 wherein said brake means comprises a hydraulically operated brake and said brake applying means comprises a hydraulic cylinder and ram with an actuating member for applying pressure via said hydraulic cylinder and ram;

said hydraulic cylinder being fluidly connected with said brake means via hydraulic brake line.

5. The safety apparatus of claim 4 wherein said hydraulic brake line includes a section that is sufficiently long and flexible to allow pivotal movement and extension of said arm outside of said window.
