[0002] In the elevator industry, safety windows are often installed on the top of the car. When people are trapped in the car, rescuers can open the safety windows from the outside and rescue the trapped people, allowing them to escape through the safety windows.

[0003] However, the safety window is too high to allow trapped people to quickly climb up to the window and escape. At the same time, as many rescue workers as possible are required to carry out the rescue, which makes it difficult to apply to cars with insufficient standing area on the roof. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an efficient elevator emergency escape device, which can achieve rapid escape by forming steps. At the same time, it is very suitable for cars with insufficient standing area on the car roof.

[0024] The present invention will be further described below through specific embodiments with reference to the accompanying drawings.

[0025] Example 1: An efficient elevator emergency escape device, such as Figure 1-3 As shown, it includes a safety window arranged on the top of the car, and the safety window includes a window frame 1 and a window plate 2.

[0026] Unlike the prior art, the window panel 2 includes multiple window panel bodies 21, each of which is connected to a suspension chain 3 that passes upward through the window frame 1 on both sides. The window frame 1 is correspondingly provided with multiple chain through holes 11, and each chain through hole 11 is provided with a chain suspension device 4 installed on the upper surface of the window frame 1. Each chain suspension device 4 can be connected to a different part of the corresponding suspension chain 3. Rescuers can arrange the multiple window panel bodies 21 at different heights and form a ladder by adjusting the connection position of each chain suspension device 4 and its corresponding suspension chain 3 on the car roof. The ladder makes it easy for trapped people to reach the window and facilitates quick escape. At the same time, there is no need for multiple rescuers on the car roof. This escape device is very suitable for cars with insufficient standing area on the car roof.

[0027] The chain suspension device 4 specifically includes a latch seat 41 and a latch 42 arranged on the latch seat 41 ; the suspension chain 3 is provided with a latch hole 318 that cooperates with the latch 42 .

[0028] A plurality of reinforcing ribs 22 are provided at the bottom of the window panel body 21 so that the window panel body 21 can bear the weight of a human body without deformation.

[0029] Better, such as Figure 4-6 As shown, the suspension chain 3 includes a plurality of chain links 31 connected to each other at the end, the top of the chain link 31 is provided with a hinge seat 311, the bottom of the chain link 31 is provided with a hinge part 312 connected to the hinge seat 311, the hinge part 312 is installed in the hinge hole 31-2 on the hinge seat 311 through the hinge shaft 31-1, the bottom of the hinge part 312 is provided with an upwardly concave mounting groove 313, the mounting groove 313 is slidably provided with an insertion rod 314, the insertion rod 314 is connected to the bottom of the mounting groove 313 through a spring 309, the top of the chain link 31 is provided with a socket 315 that can cooperate with the insertion rod 314, a pair of repelling magnets 316 are provided in the insertion rod 314 and the socket 315, and the bottom of the mounting groove 313 is provided with a rope hole 317 extending upward to the top of the chain link 31;

[0030] The suspension chain 3 further includes a connecting rope 32 , which passes through the rope hole 317 and connects the insertion rods 314 on all the chain links 31 ;

[0031] The window panel body 21 includes a lower base plate 211, a pedal board 212 arranged above the lower base plate 211, and a plurality of springs 213 arranged between the lower base plate 211 and the pedal board 212 to connect the lower base plate 211 and the pedal board 212. The pedal board 212 is connected to the lower end of the connecting rope 32.

[0032] The above-mentioned special structure of the window panel body 21 and the suspension chain 3, on the one hand, when the safety window is used normally {i.e., it does not need to be opened to form a ladder}, when the window panels 21 are folded and stacked together, due to the repulsive effect of the magnet 316 and the tension of the spring 309, the insertion rod 314 is in the installation groove 313, and the two adjacent chain links 31 can rotate with each other. Therefore, the part of the suspension chain 3 located above the car roof can change direction by rotating the chain link 31, so that it can be spread flat on the car roof or folded up, without occupying the vertical space on the car roof and without affecting the normal use of the elevator. When the ladder is folded, auxiliary equipment such as cable ties can be used to fix it. More importantly, when the trapped person steps on the pedal 212, the pedal 212 is stepped on, and the connecting rope 32 pulls down the rods 314 on all the chain links 31. At this time, the rods 314 are inserted into the corresponding sockets 315, making the suspension chain 3 a rigid structure, greatly reducing the shaking of the ladder, and further facilitating rapid escape. At the same time, the stable ladder will not collide with other people in the car, so there is little safety hazard for both the escaping person himself and other trapped people in the car.

[0033] The magnet 316 is an annular structure with an annular through hole, and the connecting rope 32 passes through the annular through hole. The chain link 31 is a plastic structure.

[0034] Preferably, the hinge seat 311 includes two parallel hinge ears 3111. A side stop 3112 connected to the top of the chain link 31 is disposed between the two hinge ears 3111. A magnet 310 is embedded in the side of the side stop 3112 facing the insertion rod 314, which is attracted to the magnet 316 on the insertion rod 314. The magnet 310 is flush with the side of the side stop 3112 facing the insertion rod 314. When the portion of the suspension chain 3 located above the car roof changes direction due to the rotation of the chain link 31, the magnet 316 rotates to a position facing the magnet 310. The magnet 310 and the magnet 316 on the insertion rod 314 are attracted to each other, which helps maintain the rotated state of the chain link 31 and prevents it from easily flipping back to an upright state. This prevents the portion of the suspension chain 3 located above the car roof from standing upright and occupying the vertical space on the car roof.

[0035] Preferably, two latch holes 318 are symmetrically provided on each link 31, and two latch pins 42 are correspondingly provided on each latch pin seat 41. By inserting the two latch pins 42 into the two latch holes 318, the suspension chain 3 can be stably suspended.

[0036] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
