Abstract

It is an escaping device from a high building, whereby an escapee can descend slowly along a rope from a high building; an escapee merely holds the grips (2) of the device to push up or down so as to have the clamping blocks (7, 8) turned so as to clamp or release the rope (10); then, the device can move downwards quickly or slowly, or stop so as to let an escapee hooked on the device descend to the ground safely. <IMAGE>

Description

A SAFETY CONTROLLER FOR HIGH-BUILDING ESCAPEE The present invention relates to escape device of the type which for high-building escapee to use.

In the present industrial society, many high buildings have been constructed. In case of fire taking place in the high building, people in the building would usually have difficulty to escape through an extension type ladder because of the height of the ladder being limited, or having too many escapees to escape; as result, some of the escapees would jump from the building to cause injuries or casualties. Some buildings have been provided with laddders or life net, but they are deemed not an ideal equi pment because of not lowering the casualties. Further, the feature of most of the conventional escape devices comprises mainly two clamping blocks to hold a rope therebetween; when the grips on the blocks are pushed up or down, the two clamping blocks would clamp or release the rope. Such a clamping device has the drawback of.

causing the rope to slide, and the space between the two clamping blcoks usually does not adapt to the diameters of some ropes; therefore, the aforesaid drawbacks in operation should be improved.

L1The present invention relates to a safety controlling device for high-building escapee, and particularly to a device which can slide downwards along a rope to convey an escapee from a high building to the ground. The device mainly comprises clamping blocks having round holes respectively to let a rope pass through. Each of the clamping blocks is mounted with a grip so as to let an escapee push the grip up or down for turning blocks to release or clutch a rope to stop the device to move downwards. When the round holes of the two blocks are in alignment and in parallel with the rope, the controller can move downwards quickly; then, the escapee belt can be hooked with a hook on the controller to move downwards so as to escapee to the ground safely.

Another feature of the present invention is to provide a controller, in which the grips thereof can be pushed up or down to ocntrol the descending speed of the controller, or to stop it for a while.

A further feature of the present invention is to provide a controller, in which there are several braking point to clutch a rope by bending the rop at an angle of 90" so as to have the controller moved downwards slowly; in that case, an escapee would not fall too quick to endanger his (or her) safety.

A preferred embodiment of the present invention will now be described. By way of example only, with reference to the accompanying diagrammatic drawings in which: FIG.1 is a perspective view of the present invention, showing the inner structure thereof.

FIG.2 is a perspective view of the present invention, showing a loose state between the clamping blocks and the rope.

FIG.6 is a perspective view of embodiment-2 according to the present invention, showing the inner structure thereof.

FIG.6-1 is a front view of the inner structure of embodiment-2 according to the present invention (showing a closely catching state between the clamping blocks and the rope).

FIG.6-2 and FIG.6-3 are front view and perspective view of the actuating bar.

FIG.7 is a perspective view of embodiment-2 according to the present invention, showing the inner structure thereof.

FIG.7-1 is a front view of the inner structure of embodiment-2 according to the present invention(showing a loose state between the clamping blocks and the rope).

FIG.7-2 and FIG.7-3 are front view and perspective view of the actuating bar.

Referring to FIG.1, there shows a perspective view of the inner structure of the present invention, in which both sides of the speed controller 1 are mounted with two speed-adjusting grips 2 respectively. The front end of each grip 2 is connected with a clamping block 3. One side of the clamping block 3 is furnished with a braking strip 5. The upper side of the clamping block 3 is mounted with a bent connecting rod 6, whereby the upper and lower clamping blocks 7 and 8 are connected and coupled with the clamping block 3-for movement. Both the upper clamping block 7 and the lower clamping block 8 are furnished with two alignedthrough-round holes 9 so as to facilitate a rope to pass therethrough. The lower part of the controller 1 has fixed pin 11 with a hook 12 extended out of the controller so as to hook an escapee there on.FIG.2 illustrates the claping blocks and the rope being set in a loose state, i.e., the rope 10 and the round hole 9 being in parallel, and the two clamping blocks 3 not clamping the rope 10; in that case, an escapee can slide downwards. Referring to FIG.3 and 4, there shows only one connecting rod 6 being connected between the upper clamping blocK 7 and the clamping blcok 3.

F1G.5 is an outer perspective view of the present invention. In case of using the present invention, tie escapee should tie one end of the rope 10 to a strong post or the like, and huve the other end OL the rope passed through the speed controller i and thrown outside of the high building; then, the hook 12 is hooked on the escapee's body. The rope 10 has to pass through th round hole 9 and the space between the two clamping blocks 3; the escapee should hole the grips 2, and then the escapee's body weight would cause the braking strips of the clamping blocks 3 to engage with the rope 10.Simultaneously, the upper and lower clamping blcoks 7 and 8 will rotate, as a result of the connecting rods 6, to bend the rope 10 to be stopped to move; the escapee can descend slowly by pushing the grips 2 upwards so as to let the braking strips 5 of the two clamping blocks 3 release the rope 10; in taht case, the round holes 9 of the upper and lower clamping blocks 7 and 8 become parallel with the rope 10, and the escapee can comfortably and safely move downwards at a controlled speed. Since the upper and lower clamping blocks 7 and 8, and the braking strips 5 can provide a double safety to the escapee.

FIG.6 and 7 illustrate embodiment-2 according to the present invention, in which the grips 2 can be connected with the grip rods 13 respectively by means of threads thereon When not in use, the grips 2 may be unscrewed and removed so as to facilitate the controller 1 to be put in a box. Each of the grip rods 13 is provided with a spring 19 thereunder so as to have the grip 2 returned to its original position after each pushing operation.

The lower sides of the fixed clamping blocks 14 and 24 are furnished with zigzag surfaces 15 and 25 to increase the friction clutch to the rope. There is a movable clamping block 16 being installed under the clamping blocks 3, which is connected with a clamping block 3 by means of a bent connecting rod 6. The center of the movable clamping block 16 has a round recess, in which an actuating bar 21 is installed to be connected with one end of the bent connecting rod 6, and whenever the connecting rod 6 is moved, the actuating bar 21 will be turned at an angle of 90 . The central part of the actuating bar has an elongate groove 20 to let the rope 10 pass through (as shown in FIG.6-2, 7-2, 6-3 and 7-3).

The lower end of the controller 1 is installed with a hanging bar 17, on which an escapee hook is to be hooked up. Under the hanging bar 17, there is rope shaft 18 for winding the rope thereon.

Referring to FIGS.6-1 and 7-1, there shows the speed controller in descending state and in friction-clutch state respectively.

After the grips 2 being pushed downwards, the clamping blocks 3 will be rotated, and simultaneously the actuating bar 21 in the movable clamping block 16 will also be turned at an angle of 90" as a result of the connecting rod 6: then, the rope that is put through the movable clamping block 16 will be bent to a frictionclutch state; the speed controller 1 is in stop condition. As soon as the grips 2 are released and lifted up by the spring, the clamping blocks 3 and the actuating bar 21 of the movable clamping block 16 actuated by the connecting rod 6 will turn reversely at an angle of 900, and then the rope 10 is released from actuating bar 21 of the clamping blocks (becoming loose). The speed controller 2 will descend again. The lower sides of the fixed clamping blocks 14 and 24 are furnished with zigzag surfaces 15 and 25 respectivly, which are opposite to the braking strips 5 on the clamping block 3 respectively so as to clutch the rope 10, and to let the controller move slowly to provide the user with an absolute safety.
