Abstract
A tall building escape apparatus includes two upright sliding rails on one side of a building where two escape exits are located. The sliding rails are cylindrical rods extended from the ground floor to the top floor of the building corresponding to hanging racks located on the top floor. The hanging racks have pulleys mounted thereon to wind a rope between the two hanging racks. The rope has two ends fastened respectively to an escape case. The escape case has retaining rollers with curved periphery to clamp the sliding rails, buffer members on the bottom side, and an entrance/exit opening on one side directing to the escape exit. When a user escapes by descending through one escape case, another escape case is pulled by the rope upwards to enable another user to escape. Thus escape speed is faster, and safety is enhanced and there is no limitation of the applicable height.
Description
- The present invention relates to a tall building escape apparatus and particularly to an escape apparatus to provide rapid escape without using power equipment.
- Public building has to provide fire fighting and escape facilities. The most commonly used escape facility is the slow descending apparatus which includes a hanging rack fixedly installed on each floor of the building and a slow descending device located nearby. In the event of fire breaking, the slow descending device is hung on the hanging rack, and a loop strap of the slow descending, device is hitched on the user. The user may descend slowly to the ground floor by means of user's own weight from the high rise building.
- However such a slow descending apparatus has drawbacks, such as the escape speed is slow, poor safety, and has limitation on the applicable height. Details of these drawbacks are elaborated as follow:
-
- 1. Slow escape speed:
- When the user has descended on the ground floor, the loop strap has to be rewound to enable the next user to descend. Not only the descending speed is slow, the winding of the loop strap is a waste of time.
- 2. Poor safety:
- During descending, the user is hitched by the loop strap and hanged in a suspended manner in the air without any traction in the surrounding. The user tends to dangle or swivel under external forces.
- 3. Limitation of applicable height:
- Because of the potential risks mentioned above, it is suitable only in the low or medium height floors.
- In view of the aforesaid disadvantages, the invention aims to provide a tall building escape apparatus that can provide rapid escape without using power equipment. The escape apparatus according to the invention includes two escape exits on one side of a building and two upright sliding rails abutting the escape exits. The sliding rails are cylindrical rods extended from the ground floor to the top floor of the building. There are hanging racks on the top floor corresponding to the sliding rails. There are pulleys fixedly mounted on the hanging racks to wind a rope. The rope has two ends each is fastened to an escape case. The escape case has retaining wheels that have a curved periphery to clamp the sliding rail. The bottom side of the escape case has buffer members. There is an entrance/exit opening located on one side of the escape case directing to the escape exit. When a user descends through one escape case, another escape case is lifted by the rope at the same time to enable another user to escape. Thus not only escape speed is faster, safety is enhanced, and there is not applicable height limitation.
- By means of the structure set forth above, the invention can provide the following advantages:
-
- 1. Faster escape:
- As there are two sets of pulleys located on the top floor of the building to wind the rope, and two escape cases are fastened to two ends of the rope, when one escape case is descended to convey an user, the rope pulls another escape case upwards at the same time to enable another user to escape. There is no waiting or waste of time.
- 2. Greater safety:
- The escape case slides downwards along the sliding rails, and the bottom side of the escape case has buffer members to provide cushion so that users may be prevented from injury when the escape case drops to the ground floor.
- 3. No height limitation:
- The two escape cases are linked by the rope and slide along the sliding rails, hence they may be used securely without height limitation. Moreover, descending and lifting of the escape cases are steadier.
- The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
-
FIG. 1 is a front view of the present invention. -
FIG. 2 is a side view of the present invention. -
FIG. 3 is a top view of the present invention. -
FIG. 4 is a cross section of the escape case of the invention. -
FIG. 5 is a fragmentary cross section of the brake device of the invention. -
FIG. 6 is a schematic view of an embodiment of the invention. - Please referring to
FIGS. 1, 2 and 3, the tall building escape apparatus according to the invention includes at least two escape exits on each floor of abuilding 10 that may be escapedoors 11, or escape windows or balconies. The drawings show theescape doors 11 as an example. On one side of theescape door 11, there are two upright and parallel slidingrails 23 that are extended from the ground floor to the top floor of thebuilding 10. The slidingrails 23 are cylindrical rods. The top floor of thebuilding 10 has two hangingracks 20 on the edge corresponding to thesliding rails 23 that are extended outside the edge of thebuilding 10. The bottom side of the hanging rack has twopulleys 21 fastened thereon in a front and a rear manner. Thepulleys 21 at the front side are wound by arope 22. Thepulleys 21 at the rear side also are wound by anotherrope 22. Therope 22 winds thepulleys 21 at least one time. Therope 22 has two ends fastened respectively the twoescape cases 30. - Referring to
FIG. 4 , theescape case 30 has a plurality pairs ofretaining rollers 33 which have a curved periphery to clamp the cylindrical slidingrail 33 without moving away. The bottom side of theescape case 30 hasbuffer members 36 for damping purpose. In the drawings, thebuffer members 36 are springs. Theescape case 30 is hollow and has an entrance/exit opening 31 directing to theescape door 11. The bottom edge of the entrance/exit opening 31 is extended to form anextension board 32. Referring toFIG. 5 , theescape case 30 further has at least twobrake devices pivotal clamp member rail 23. Theclamp member braking pad rail 23, and an inner end bridged by anelastic member braking pads rail 23 constantly. When the inner end of theclamp member 341 is subjected to a clamping force, the outer end may be extended to make thebraking pad 342 moving away from the slidingrail 23 to release the compression. One inner end of theclamp member 351 of onebrake device 35 has abrake line 354 which is connected to apedal 355. When thepedal 355 is stepped and depressed, the outer ends of theclamp member 351 are extended to release thebraking pad 352 from compressing the slidingrail 23. - Referring to
FIG. 6 , when in use, people on each floor of thebuilding 10 may enter theescape case 30 through theescape door 11 and theextension board 32. Once entered the escape case, user can use hands to extend the outer ends of thebrake device 34 and use one foot to step thepedal 355 of anotherbrake device 35 to extend the outer ends of theclamp member 351 so that the twobraking pads brake devices rail 23, and theescape case 30 may slide downwards. During descending, user can control the sliding speed of theescape case 30 through thebrake devices escape case 30 drops to the ground floor, thebuffer members 36 provide a damping and shock absorbing effect to prevent the user from injury. Meanwhile, anotherescape case 30 is pulled by therope 22 and lifted upwards to enable another user to escape rapidly.
