Description

Technical Field

[0001] The invention relates to a building escape facility, in particular to an escape ladder on a building exterior wall and a combined window containing the escape ladder. Background Art

[0002] At present, buildings are generally more than three stories high, whether they are residential houses, shopping malls, factories or office buildings. Once a fire occurs, the corridors are blocked by fire and smoke, and people in the buildings above the flames are basically in a state of seeking help. During the time it takes for the fire truck to arrive, many people may die. Even if the fire truck finally arrives, they may not be rescued if the fire is too big. Some people even choose to jump off the building to survive and die. Once such an unfortunate situation occurs, the scene is horrific and causes serious harm to many families.

[0003] Therefore, the most critical thing is to quickly and safely leave the building at the onset of a fire. Some floors are currently equipped with escape ladders, portable ladders designed to rescue and evacuate people trapped in a fire. These stowable ladders are effective life-saving tools in critical situations where stairways are blocked during a fire or accident. Conventional escape ladders are simple in structure, relying solely on two metal hooks at the top to attach to a raised surface such as a roof or window sill. Furthermore, the ladder itself clings tightly to the wall, making it difficult for trapped people to place their mid-foot on the ladder as they climb down. They can only touch the ladder with their toes, making it difficult to grasp the ladder with their hands. Climbing down is slow, and the intense pressure can easily lead to falls. In large crowds, the risk of falling is even greater, creating a significant risk of trampling and falling. Furthermore, if the wall is heated by fire, contact with it can cause burns, making it impossible to climb down and resulting in a fall.

[0004] For these reasons, the applicant previously developed and patented an escape facility, patent number ZL201821846595.2, entitled "An escape ladder for a building's exterior wall window and a combined casement window incorporating an escape ladder." This facility achieved excellent technical results during trials. However, some drawbacks remain. For example, when the user group is the elderly and children, due to their fear and poor physical fitness, these two groups may become nervous and unable to climb out of the window, or may fall in the process. Therefore, further upgrades and improvements are necessary. Summary of the Invention

[0005] In response to the above problems, the present invention aims to provide an escape ladder on the exterior wall of a building and a combination window including an escape ladder.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the present invention provides an escape ladder for the exterior wall of a building, comprising a frame 2 fixedly mounted in a wall 1, wherein the bottom surface of the frame 2 corresponds to the ground height of the floor, the inner and outer sides of the frame 2 are respectively located indoors and outdoors, and the inner bottom of the inner side of the frame 2 is hinged with an inner panel 3 that opens inwards, and the top of the inner panel 3 is detachably connected to the top of the frame 2, and the outer bottom of the outer side of the frame 2 is hinged with an outer panel 4 that opens outwards, and both the inner panel 3 and the outer panel 4 are opened from the inside; the outer panel 4 comprises an upper sealing plate 41 and a lower connecting plate 42 that are hinged to each other, the top of the upper sealing plate 41 is detachably connected to the top of the frame 2, and the bottom of the lower connecting plate 42 is hinged to the bottom of the frame 2, and a soft ladder 5 is arranged in the frame 2.

[0027] On the basis of the above scheme, a descender 6 is provided on the top of the frame 2, and a soft rope 7 for tying around the waist is connected to the descender 6. A soft rope self-locking buckle 17 is provided at the end of the soft rope 7. After the soft rope 7 is wrapped around the waist, it is locked with the soft rope self-locking buckle 17, which makes assembly and disassembly quick.

[0028] Preferably, the bottom of the frame 2 is laterally connected to mutually parallel metal fixing rods 8 near the inside and outside, respectively. The inner panel 3 is hinged to the inner metal fixing rod 8 via hinge 1 9, and the lower connecting plate 42 is hinged to the outer metal fixing rod 8 via hinge 2 10. The two ends of the metal fixing rod 8 pass through the frame 2 and are located within the wall. The metal fixing rod 8 near the outside is particularly important as it primarily bears weight during use and therefore requires high strength and rigidity. The flexible ladder 5 is connected to the metal fixing rod 8 near the outside of the bottom of the frame 2. The inner top of the lower connecting plate 42 is laterally connected to connecting rod 1 11, and the inner bottom of the upper sealing plate 41 is laterally connected to connecting rod 2 12. The connecting rod 1 11 and connecting rod 2 12 are hinged together via a hinge kit 13 to ensure the reliability and strength of the connection between the upper sealing plate 41 and the lower connecting plate 42.

[0029] Furthermore, the height of the lower connecting plate 42 is 15cm-20cm, which ensures that after the outer panel 4 is opened outward, the lower connecting plate 42 is spread outward on the ground and the upper sealing plate 41 remains in a free vertical state downward. When the soft ladder 5 is lowered, the gap from the outer wall is 15cm-20cm. When the user climbs down, the toes can just touch the wall surface of the outer wall when climbing the next soft ladder step, which can give the user a safe auxiliary positioning in his mind, increase the psychological sense of security, and try to eliminate the possibility of stepping on air due to nervousness during actual use.

[0030] In addition, an operating handle 14 is provided on the top of the inner panel 3, and a door lock 15 is provided at the operating handle 14. The door lock 15 can be locked at ordinary times to prevent people from opening it and playing with the facilities inside, thereby increasing the safety of the facilities. In addition, the keys can be uniformly planned and placed in a designated place near the facilities. In case of emergency, the key can be taken out to open the door lock 15 and open the facility by operating the handle 14.

[0031] In addition, a safety hammer 16 for breaking glass windows is provided on the inner side of the frame 2. People can carry the safety hammer with them when climbing down. When they climb down to a floor below the height of the fire, they can break the glass of other people's houses and enter other people's rooms. In this case, it can constitute emergency avoidance and the person does not need to bear criminal responsibility, and can escape down the stairs.

[0032] Finally, the top of the outer plate 4 is connected to a locking block 18 with an inner hole, and a limit block 19 is correspondingly provided on the top of the inner plate 3. A hinged rod 20 is fixed to the lower surface of the top of the frame 2, and the lower end of the hinged rod 20 is hinged to a connecting rod 3 21. The connecting rod 3 21 is provided with a card column 22 extending into the inner hole of the locking block 18 near the outer end. The lower surface of the top of the frame 2 is connected to a spring mounting seat 23, and a compression spring 24 is installed in the spring mounting seat 23. The other end of the compression spring 24 abuts against the connecting rod When the inner panel 3 is closed, the compression spring 24 presses the inner end of the connecting rod 3 21 so that the inner end of the connecting rod 3 21 abuts against the limit block 19. At this time, the clamping column 22 of the outer end of the connecting rod 3 21 is engaged with the inner hole of the locking block 18. When the inner panel 3 is opened, the limit block 19 opens with the inner panel 3, and the compression spring 24 pushes the inner end of the connecting rod 3 21 away. The connecting rod 3 21 rotates around the central hinge rod 20, and the outer end of the connecting rod 3 21 disengages from the inner hole of the locking block 18, and the outer panel 4 automatically opens. Ultimately, when the inner panel 3 is opened, the outer panel 4 is opened in conjunction with it, thereby increasing the speed at which the outer panel 4 opens. In addition, a bevel is provided at the inner end of the connecting rod three 21, and the inclination direction is close to the limit block 19. When the inner plate 3 is closed, the limit block 19 squeezes the bevel to make the connecting rod three 21 rotate, and finally makes the clamping column 22 at the outer end of the connecting rod three 21 extend into the inner hole of the locking block 18 and lock it.

[0033] In addition, the present invention also provides a combination window including an escape ladder, including a frame 2 fixedly installed in the wall 1, the bottom surface of the frame 2 corresponds to the ground height of the floor, the inner and outer sides of the frame 2 are respectively located indoors and outside, the inner bottom of the frame 2 is hinged with an inner panel 3 that opens inward, the top of the inner panel 3 is detachably connected to the top of the frame 2, and the outer bottom of the frame 2 is hinged with an outer panel 4 that opens outward, and both the inner panel 3 and the outer panel 4 are opened from the inside; the outer panel 4 includes an upper sealing plate 41 and a lower connecting plate 42 that are hinged to each other, the top of the upper sealing plate 41 is detachably connected to the top of the frame 2, and the bottom of the lower connecting plate 42 is hinged to the bottom of the frame 2, a soft ladder 5 is arranged in the frame 2, the top of the frame 2 is connected to the window outer frame, the inner and outer sides of the window outer frame pass through the wall, and the lower end of the window outer frame is fixedly connected to the frame 2.

[0034] Based on the above solution, an outward-opening window or a casement window is provided in the window outer frame.

[0035] The escape ladder can be installed alone in places without windows, or it can be installed in combination with windows. When in use, take out the key on the floor, open the inner panel 3 inward and lay it flat on the ground, reach into the frame to open the outer panel 4, and open the upper sealing plate 41 and the lower connecting plate 42 outward. The lower connecting plate 42 is spread flat on the ground and extends horizontally outward, while the upper sealing plate 41 remains in a vertical state. Push the soft ladder 5 outward and let it fall freely. Tie the soft rope on the descender 6 around your waist, bring a safety hammer, lie on the ground with your feet outward, slowly exit outside, step on the soft ladder 5 and slowly climb down. If the floor is lower, you can directly climb to the bottom to escape. If the floor is higher, climb below the fire floor and break the glass windows of other people's houses to enter the room and escape from the stairs. It is especially suitable for the safe escape of vulnerable groups such as the elderly and children.

[0036] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the invention. Any simple modification, equivalent change or modification made to the above embodiment based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
