Definitions
- the present invention relates to a rescue system for use when evacuating high buildings or the like.
- the rescue system consists of a rope and a lowering mechanism, a fastening device to the building, and a housing.
- means of escape can be provided either by ladders put up by people outside the building, or ladder trucks, or ladders mounted on the building itself, and which can be released from the desired height by the people preparing to evacuate the building.
- Another common piece of equipment is a rescue rope consisting of a lowering mechanism, a harness which the person can slip into, and a suspension system. This type of rescue rope is normally hanging on a hook by a window on the inside of the building, and it can be let out of the window when needed.
- One object of the present invention is to provide a complete rescue system with a secure mounting to the building, maintenance-free storage after installation, and a reliable lowering and braking function. It is a further object of the present invention to combine a maintenance-free device with the possibility of lowering people alternately at both ends of the rope for optimum capacity.
- Fig. 1 is a cross-sectional view of the lowering and braking mechanism.
- Fig. 2 is a cross-sectional view of the same mechanism taken along the line A-A of Fig. 1.
- Fig. 3 illustrates the principle of a loop rope between harnesses.
- Fig. 4a is a front view of the fastening bracket for the rope housing.
- Fig. 4b is a cross-sectional view of the fastening bracket of Fig. 4a.
- This invention is composed of a rope housing 1 containing a braking mechanism.
- the rope housing 1 acts also as suspension device for the entire system, its upper extremity being provided with a suspension hole 2 which is used to suspend the device of this invention to a wall.
- a space 3 for the mechanism is provided, having an upper part of a semi-circular shape and a lower part approximately in the shape of a rectangle.
- an opening 4 is provided perpendicular to that side.
- a circular pulley 5 is provided, the centre axis 6 of which is part of the rope housing 1.
- a locking pin 7 is placed between the pulley 5 and the centre axis 6 to prevent the pulley 5 from rotating.
- the pulley 5 is designed with a V-groove 8 in which a rope 9 lies.
- the surface of the groove 8 is corrugated or has any other appropriate surface providing the necessary roughness to increase friction.
- the rope 9 is threaded into the space 3 for the mechanism through the opening 4, runs over the pulley 5, and runs out again through the opening 4 parallel with the incoming length of rope.
- the opening 4 is funnel shaped and its inside face can be provided with a rough surface. Moreover, the narrowest end of the funnel-shaped opening has such a diameter that the incoming and outgoing lengths of the rope 9 will be somewhat squeezed together, and a further friction effect is therefore obtained in addition to the friction between the rope 9 and the pulley 5, thus giving further braking effect.
- the force with which the rope 9 is being pulled upon determines the depth of the rope 9 inside the groove.
- a friction mechanism is therefore obtained where the amount of friction is determined by the person's weight, and the velocity of descent will be the same for any person, regardless of their weight.
- the next person can use the other end of the rope to lower themselves.
- the device of the present invention can therefore be used at optimal capacity when a harness is attached at each end of the rope 9.
- the device of the present invention also offers the possibility of attaching a baby harness or a carrying bag for babies to the adult harness, thus increasing the capacity.
- the device of the present invention comprises no moving part requiring maintenance to ensure reliable function.
- Figure 3 shows the principle by which the rope 9 is prolonged between harness S 1 and harness S2 to give a person lowering himself or herself in one of the harnesses the possibility to regulate and decrease their speed of descent by holding the rope on the opposite side of the pulley 5. Holding the opposite extremity of the rope 9 will cause the rope 9 to slide deeper into the groove 8 of the pulley 5 and thus increase the braking effect.
- Figure 2 illustrates also a housing cover 10 placed in front of the rope housing 1, covering the pulley 5, and slightly wider than the rope housing 1. The wider edges are used to attach the outer cover so that the rescue system becomes a closed unit.
- a suspension hole 2 is provided in the rope housing 1.
- This allows the rope housing 1 to be connected to a fastening bracket 11 illustrated on figures 4a and 4b.
- a corresponding rope housing hole 12 is provided in the lower half of the fastening bracket 11. Such a connection permits the rope housing 1 to effect a sideways swinging motion about the suspension point for the fastening bracket 11.
- the upper half of the fastening bracket 11 has several types of holes for mounting the bracket itself and the rescue system to a wall or the like.
- the mounting holes 13 are provided for mounting the fastening bracket 11 to a timber wall or structure. The position of the mounting holes 13 relative to one another prevents the timber from splitting during mounting, as a vertical alignment of the holes is thus avoided.
- the central fastening hole 14 is used to suspend the rescue system from a hook when such a hook is available.
- the upper and the lower halves of the fastening bracket 11 are positioned in such a manner that they stand each in their individual plane, both planes being parallel to each other. These planes are also approximately parallel to the plane of any wall on which the rescue system may be mounted.
