In one embodiment, referring to fig. 1 and 3, an escape apparatus 100 for use in a facade comprises: a column 110 and a first pedal assembly 120. The first pedal assembly 120 includes a first pedal 121 and a first support 122. The first pedal 121 is rotatably mounted on the upright 110. The first supporting member 122 is disposed between the first pedal 121 and the upright 110. The first support 122 can be folded or unfolded on the column 110. When the first support 122 is opened on the upright 110, the first step 121 can be supported on the upright 110 by the first support 122.

In the assembly process of the escape device 100 for the facade, the upright post 110 is firstly arranged on the facade of the building; the first pedal 121 assembly is then mounted on the upright 110. The first pedal assembly 120 is folded and leaned on the upright post 110 in a normal state, so that the first pedal assembly does not occupy extra space, is beneficial to reducing the occupied area in a building and expanding the escape or rescue space. When a fire or other accident occurs, the first step 121 is fallen down by its own weight or by electric driving. Meanwhile, the first supporting member 122 is unfolded from the upright 110 such that one end thereof is supported on the first step 121 and the other end thereof is supported on the upright 110, thereby ensuring that the first step 121 can be stably supported on the upright 110 and providing a climbing and stepping passage for the evacuee. Because the outer vertical face escape device 100 is simple in structural design, quick to open and convenient to operate, more precious escape time is won for an escaper, and the life safety of the escaper is effectively guaranteed.

Specifically, the upright post 110 is arranged on the outer facade of the building, which is beneficial to saving the inner space of the building, so that the escape passage cannot be blocked due to the accumulation of sundries. On the other hand, the upright post 110 is arranged on the outer facade of the building, which is also beneficial to keeping away from the fire source when a fire disaster occurs, and is convenient for firefighters to assist in escape operation.

It should be noted that folding is understood as: after rotating, the first support 122 can be stacked on the upright 110 to reduce the lateral space of the upright 110. Meanwhile, the first pedal 121 and the first support 122 may be directly mounted or indirectly mounted on the upright 110. When the first pedal 121 and the first support 122 are indirectly mounted on the upright 110, an intermediate structure is provided between the first pedal 121 and the first support 122 and the upright 110.

Further, referring to fig. 1, the first step 121 is mounted on the upright 110 in a hinged manner. Therefore, the first pedal 121 is rotated and lowered around the hinge at the joint with the upright post 110, so that the lowering action of the first pedal 121 is smoother and more stable, and the starting time of the facade escape apparatus 100 is shortened.

It should be noted that, the first supporting member 122 disposed between the first pedal 121 and the upright 110 is understood as: the first support 122 has one end connected to the first step 121 and the other end connected to the upright 110. Therefore, the upright column 110, the first pedal 121 and the first supporting member 122 form a stable triangular structure, and when the first supporting member 122 is opened on the upright column 110, the first pedal 121 can be stably supported on the upright column 110 through the first supporting member 122.

In one embodiment, referring to fig. 1, one of the first pedal 121 and the upright 110 is rotatably connected to the first supporting member 122, and the other is slidably connected to the first supporting member 122.

It should be noted that, in both the first pedal 121 and the upright 110, one of them is rotatably connected to the first support 122, and the other is slidably connected to the first support 122, which should be understood as: the first support member 122 is connected between the first pedal 121 and the upright 110 in two ways, i.e., the first pedal 121 is rotatably connected with the first support member 122, and the upright 110 is slidably connected with the first support member 122. Thus, when the first support 122 is opened on the upright 110, one end of the first support 122 rotates around the connection with the first pedal 121, and the other end of the first support 122 is connected with the upright 110 and slides downwards, so that the first pedal 121 can be lowered; second, the first pedal 121 is slidably connected to the first supporting member 122, and the upright 110 is rotatably connected to the first supporting member 122. When the first supporting member 122 is opened on the upright 110, one end of the first supporting member 122 rotates around the joint with the upright 110, and the other end of the first supporting member 122 connected with the first pedal 121 slides in a direction away from the upright 110, so that the first pedal 121 is stably lowered.

Specifically, referring to fig. 1, the sliding distance of the first support 122 on the first pedal 121 is a fixed distance. Thus, when the first supporting member 122 is opened from the upright 110, the first supporting member 122 will rotate around the connecting fulcrum on the upright 110, and at this time, one end of the first supporting member 122 will slide on the first pedal 121 accordingly. When the first pedal 121 is rotated to a certain angle, the position of one end of the first supporting member 122 on the first pedal 121 is just located at one end of the fixed distance, so that one end of the first supporting member 122 cannot slide on the first pedal 121, and thus the first pedal 121 is fixed at a certain angle and does not rotate downwards, and the first pedal 121 is stably supported on the upright 110.

Further, the sliding distance of the first support 122 on the upright 110 is a fixed distance. Thus, when the first supporting member 122 is opened on the upright 110, the first supporting member 122 will rotate around the connecting fulcrum of the first pedal assembly 121, and at this time, one end of the first supporting member 122 will slide on the upright 11 accordingly. When the first pedal 121 is rotated to a certain angle, the position of one end of the first supporting member 122 on the upright 110 is just located at one end of the fixed distance, so that one end of the first supporting member 122 cannot slide on the upright 110, and the first pedal 121 is fixed at a certain angle and does not rotate downwards, and the first pedal 121 is stably supported on the upright 110.

In one embodiment, referring to fig. 3, the escape apparatus 100 further includes a first guide 130, the first guide 130 is disposed along the height direction of the vertical column 110. The first supporting member 122 is disposed between the first pedal 121 and the first guide rail 130, and one of the first pedal 121 and the first guide rail 130 is rotatably connected to the first supporting member 122, and the other is slidably connected to the first supporting member 122. Therefore, the first guide rail 130 is provided to facilitate the first supporting member 122 to slide on the first guide rail 130 more smoothly, so that the opening process of the first pedal assembly 120 is smoother, which is beneficial to saving the starting time of the facade escape apparatus 100, thereby providing more precious escape time for the evacuees.

It should be noted that, in both the first pedal 121 and the first guide rail 130, one of them is rotatably connected with the first support 122, and the other is slidably connected with the first support 122, it should be understood that: there are two ways of connecting the first support 122 between the first step 121 and the first rail 130. The first is that the first pedal 121 is rotatably connected to the first support 122, and the first guide 130 is slidably connected to the first support 122. Thus, when the first supporter 122 is opened on the upright 110, one end of the first supporter 122 rotates around the connection with the first step 121, and the other end of the first supporter 122 connected to the first rail 130 slides downward, so that the first step 121 is lowered. The second is that the first pedal 121 is slidably connected to the first support 122, and the first guide 130 is rotatably connected to the first support 122. Thus, when the first supporting member 122 is opened on the upright 110, one end of the first supporting member 122 rotates around the connection with the upright 110, and the other end of the first supporting member 122 connected with the first pedal 121 slides away from the first guide 130, so that the first pedal 121 is lowered.

In one embodiment, referring to fig. 3, in both the first pedal 121 and the first guide rail 130, the first pedal 121 is slidably connected to one end of the first supporting member 122, and the other end of the first supporting member 122 is rotatably connected to the first guide rail 130. Therefore, the first pedal assembly 120 can be smoothly unfolded, and the starting time of the facade escape device 100 can be shortened, so that more precious escape time can be provided for the evacuees.

Specifically, the first pedal 121 is slidably connected to the first support 122 by providing a guide groove on the first pedal assembly 120 and a positioning pin on the first support 122. Thus, the opening of the first step assembly 120 on the upright 110 is completed by the matching sliding of the positioning pin and the guide groove.

Further, referring to fig. 3, in the present embodiment, the length of the guiding groove is smaller than the length of the first step 121. Therefore, when the first pedal 121 is opened on the upright post 110, the first pedal 121, the first guide rail 130 and the first supporting member 122 form a triangular stable structure, which is beneficial for the first pedal 121 to be stably supported on the guide rail, and improves the safety of the facade escape apparatus 100.

In one embodiment, referring to fig. 3, the number of the first pedal assemblies 120 is two or more, and the two or more first pedal assemblies 120 are spaced apart from each other in the height direction of the first guide rail 130. Therefore, more than two first pedal assemblies 120 are arranged on the upright post 110 to form a ladder stand structure, so that rescue workers trapped at high buildings climb downwards to escape, and a fire fighter is prevented from entering a fire scene to rescue the trapped workers.

For the convenience of clearly understanding the height direction of the first guide rail 130 of the present embodiment, taking fig. 1 as an example, the height direction of the first guide rail 130 is S in fig. 1₁The direction indicated by any arrow.

In one embodiment, referring to fig. 1 and 3, the facade escape apparatus 100 further includes a second step assembly 140. The first pedal assembly 120 and the second pedal assembly 140 are respectively located at two opposite sides of the upright 110, and the second pedal assembly 140 can be folded or unfolded on the upright 110. Therefore, the first pedal assembly 120 and the second pedal assembly 140 are respectively arranged at two opposite sides of the upright post 110, which is beneficial for the escape personnel to more stably climb and escape; meanwhile, the escape personnel can climb on the two sides of the upright post 110 for escape, so that the escape time is saved, and the rescue process is accelerated.

Further, referring to fig. 3, the second pedal assembly 140 includes a second pedal 141 and a second supporting member 142, the second pedal 141 is rotatably mounted on the upright 110, the second supporting member 142 is disposed between the second pedal 141 and the upright 110, the second supporting member 142 can be folded or unfolded on the upright 110, and when the second supporting member 142 is unfolded, the second pedal 141 can be supported on the upright 110 through the second supporting member 142. Thus, the second pedal assembly 140 has the same structure and function as the first pedal assembly 120, which is beneficial to improving the use effect of the facade escape apparatus 100. Under a normal state, the second pedal assembly 140 is folded and leaned on the upright post 110, so that extra space is not occupied, the occupied area in a building is reduced, and the escape or rescue space is enlarged. When a fire or other accidents happen, the first pedal 121 falls down by its own weight, and meanwhile, the second supporting member 142 is opened on the upright post 110, one end of which is supported on the second pedal 141 and the other end of which is supported on the upright post 110, so that the first pedal 121 can stably maintain the falling state, which is beneficial to striving for more precious escape time for evacuees.

In one embodiment, referring to fig. 3, the escape apparatus 100 further includes a second guide rail 150, the second guide rail 150 is disposed along the height direction of the upright 110, the second guide rail 150 and the first guide rail 130 are disposed at two opposite sides of the upright 110, and the second pedal assembly 140 is disposed on the second guide rail 150. Therefore, the second guide rail 150 is additionally arranged between the upright post 110 and the second pedal assembly 140, so that the second supporting member 142 can slide more smoothly, the opening process of the second pedal assembly 140 can be smoother, the starting time of the facade escape device 100 can be saved, and more precious escape time can be provided for the evacuees.

In order to facilitate clear understanding of the height direction of the second guide rail 150 of the present embodiment, taking fig. 1 as an example, the height direction of the second guide rail 150 is S in fig. 1₂The direction indicated by any arrow.

Further, referring to fig. 3, between the second pedal 141 and the second guide rail 150, one is rotatably connected to the first supporting member 122, and the other is slidably connected to the second supporting member 142. Therefore, the starting time of the escape device 100 for the facade is saved, and more valuable escape time is provided for the evacuees.

It should be noted that, between the second pedal 141 and the second guide rail 150, one of them is rotatably connected to the second support 142, and the other is slidably connected to the second support 142, which should be understood as: the second supporter 142 is connected between the second step 141 and the second rail 150 in two ways. The first is that the second pedal 141 is rotatably connected to the second support 142, and the second rail 150 is slidably connected to the second support 142. Thus, when the second supporter 142 is opened on the pillar 110, one end of the second supporter 142 rotates around the connection with the second step 141, and the other end of the second supporter 142, which is connected with the second rail 150, slides downward, so that the second step 141 is lowered. The second is that the second pedal 141 is slidably connected to the second support 142, and the second rail 150 is rotatably connected to the second support 142. Thus, when the second supporter 142 is opened on the upright 110, one end of the second supporter 142 rotates around the connection with the upright 110, and the other end of the second supporter 142 connected to the second step 141 slides away from the second rail 150, so that the second step 141 is lowered.

In one embodiment, referring to fig. 1 and fig. 3, the first pedal 121 is provided with a first positioning portion 123, the upright column 110 is provided with a second positioning portion 112, and when the first pedal 121 rotates to the upright column 110, the first positioning portion 123 is in positioning fit with the second positioning portion 112. Thus, when the first pedal assembly 120 is folded, the first positioning portion 123 and the second positioning portion 112 are positioned and matched to ensure that the first pedal 121 is stably folded on the upright column, which is beneficial to saving building space; meanwhile, the outer facade of the building is more attractive.

Alternatively, the first positioning portion 123 and the second positioning portion 112 may be engaged by a snap fit, a hole-shaft interference fit, a magnetic attraction fit, or other engagement methods.

Further, referring to fig. 1, in the present embodiment, the first positioning portion 123 and the second positioning portion 112 are magnetically coupled. The first positioning portion 123 is made of a ferromagnetic material. The second positioning portion 112 is an electromagnet. Thus, in the normal state, the electromagnet is energized, so that the first pedal assembly 120 is kept in the state of being folded on the upright post 110; when a fire disaster or other conditions occur, the electromagnet is powered off, the first pedal 121 is opened on the upright post 110 by means of self weight, the structure is simple, the response time is short, and escape personnel can be enabled to break away from the fire scene more quickly. The first positioning portion 123 and the second positioning portion 112 are matched with the first pedal assembly 120 to open, but the present embodiment provides a simpler manner, and is not limited thereto.

Further, referring to fig. 1 and fig. 3, the second pedal 141 is also provided with a first positioning portion 123, the upright column 110 is provided with a second positioning portion 112, and when the second pedal 141 rotates to the upright column 110, the first positioning portion 123 is in positioning fit with the second positioning portion 112. Thus, when the second pedal assembly 140 is folded, the first positioning portion 123 and the second positioning portion 112 are also used for positioning and matching, which is beneficial to saving building space; meanwhile, the outer facade of the building is more attractive.

In one embodiment, referring to fig. 2, a drainage channel 111 is provided in the column 110. Therefore, in a conventional state of the escape device 100 for the facade, the drainage channel 111 can be used as a drainage pipeline for the facade, and has a normal drainage function, so that the utilization rate of the building space is improved, and the internal space of the building is saved.

In one embodiment, referring to fig. 1-4, a facade escape system includes a trigger, a controller and a facade escape apparatus 100 according to any of the above embodiments. The trigger piece is electrically connected with the controller and used for sending a working signal to the controller. The controller is used for controlling the first pedal 121 to be supported on the upright 110 through the first support 122 after acquiring the working signal.

In the escape system for the outer vertical surface, in the assembling process, the upright post 110 is firstly arranged on the outer vertical surface of the building; the first pedal 121 assembly is then mounted on the upright 110. The first pedal assembly 120 is folded and leaned on the upright post 110 in a normal state, so that the first pedal assembly does not occupy extra space, is beneficial to reducing the occupied area in a building and expanding the escape or rescue space. When a fire or other accident occurs, the first step 121 is fallen down by its own weight or by electric driving. Meanwhile, the first supporting member 122 is unfolded from the upright 110 such that one end thereof is supported on the first step 121 and the other end thereof is supported on the upright 110, thereby ensuring that the first step 121 can be stably supported on the upright 110 and providing a climbing and stepping passage for the evacuee. Because the outer vertical face escape device 100 is simple in structural design, quick to open and convenient to operate, more precious escape time is won for an escaper, and the life safety of the escaper is effectively guaranteed.

In particular, the trigger may be a sensor switch or a manual switch. Thus, the escape system for the facade comprises two triggering modes: the first is that the sensor is electrically connected with the controller. The sensor is used for sending an operating signal to the controller. After receiving the working signal, the controller starts the facade escape device 100, so that the first pedal assembly 120 and/or the second pedal assembly 140 is changed from the folding state to the opening state; the second is that the manual switch is electrically connected to the controller, the manual switch is used to send a working signal to the controller, and the controller starts the facade escape apparatus 100 after receiving the working signal, so that the first pedal assembly 120 and/or the second pedal assembly 140 is changed from the folded state to the opened state.

It should be noted that the controller, upon receiving the operation signal, activates the facade escape apparatus 100 such that the first step assembly 120 and/or the second step assembly 140 changes from the folded state to the open state, should be understood as: there are three ways for the controller to activate the facade escape apparatus 100 after receiving the operation signal. The first is to change the first pedal assembly 120 from the folded state to the open state. The second is to change the second pedal assembly 140 from the folded state to the open state. The third is to change the first pedal assembly 120 and the second pedal assembly 140 from the folded state to the open state.
