Description

Technical Field

[0001] The invention relates to the technical field of fire safety escape, and in particular to an aging-friendly flexible escape mechanism. Background Art

[0002] In emergencies such as fires, disabled elderly people are the most vulnerable and the most difficult to evacuate, and often become the main source of casualties in fire accidents in related facilities.

[0003] The evacuation passage has limited traffic capacity, and it is very likely that all personnel in large buildings will not be able to evacuate in the first place. Therefore, existing related research and technical inventions have proposed to set up an evacuation slide located outside the building to assist personnel in evacuating (high-rise building conjoined escape slide, CN201910386377.8, a high-rise escape slide, CN201910110304.6, a high-rise building escape system, CN201410284125.1). However, disabled elderly people do not have the ability to take care of themselves or even the ability to perceive, and it is impossible to independently complete the entire process of going to the slide position, using the slide, and leaving the slide. Even if you reluctantly enter the slide with the assistance of a caregiver, you are likely to be injured during use and after leaving the slide, and the time and physical strength consumed by the caregiver to assist the elderly in moving and using the slide may be equivalent to the consumption of direct evacuation. Therefore, it is urgent to propose an aging-friendly improvement plan for a flexible escape slide to solve the problem of insufficient efficiency and safety when the disabled elderly group uses the slide.

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0044] Referring to Figures 1-7 , the present invention provides an aging-friendly flexible escape mechanism, including:

[0045] An accommodation box 1, which is arranged on the building wall;

[0046] An expandable escape slide 2, which is arranged in the accommodation box 1, and the escape slide 2 can extend out of the accommodation box 1 to form a continuous descending channel when unfolded;

[0047] A protective stretcher 3, which can carry disabled elderly people and slide through the escape slide 2;

[0048] An expandable buffer air cushion 4, which is arranged at the outlet end of the escape slide 2, and the buffer air cushion 4 is used to receive and protect the protective stretcher 3 and the disabled elderly people;

[0049] An inflation mechanism, which can quickly inflate and expand the buffer air cushion 4;

[0050] Multiple extension rings 5 are arranged at intervals on the escape slide 2. The extension rings 5 are used to provide rigid support and stabilize the shape of the escape slide 2 after the escape slide 2 is deployed, and play a role in providing rigid support for the entrance position and the end position of the inclined escape area 201 to avoid stretcher jamming, shaping the shape of the escape slide 2 to stabilize the descent speed after the escape slide 2 is released, and serving as the fixed points of the escape slide 2 in the storage state.

[0051] A control release mechanism is in transmission cooperation with multiple extension rings 5 and an inflation mechanism. The control release mechanism is used to gradually release the escape slide 2 for deployment and activate the inflation mechanism when the escape slide 2 is deployed.

[0052] By gradually releasing the escape slide 2 through the control release mechanism and simultaneously activating the inflation mechanism to inflate the buffer air cushion 4, the escape slide 2 and the buffer air cushion 4 can quickly form a flexible escape structure. Together with the protective stretcher 3, it can be used for the rapid transfer and escape of disabled elderly people in scenarios such as hospitals and nursing homes, saving the physical strength and time of rescue personnel such as nursing workers, and completing the evacuation of disabled elderly people as efficiently and safely as possible.

[0053] Furthermore, the escape slide 2 is divided into a multi-layer structure. The outermost layer is a fireproof and wear-resistant layer, made of a composite material of ceramic fiber and basalt coating. The second layer is a structure strengthening layer, composed of an aramid fiber woven mesh. The third layer is an impact-resistant buffer layer, preferably made of a composite material of silica gel and memory foam. The inner layer is an anti-slip layer, preferably made of thermoplastic polyurethane material.

[0054] In an embodiment of the present invention, the control release mechanism includes:

[0055] A control connecting rod 6 is rotatably connected in the accommodation box 1 through a fixing member 7. One end of the control connecting rod 6 close to the inlet end of the accommodation box 1 is provided with a rotating grip 8.

[0056] Multiple first buckles 9 are fixedly connected to the control connecting rod 6. The multiple first buckles 9 correspond to the multiple extension rings 5 one by one. First slots for engaging with the first buckles 9 are formed on the extension rings 5.

[0057] By operating the rotating grip 8 to rotate the control connecting rod 6, multiple extension rings 5 can be quickly and gradually released through the cooperation of the first buckles 9 and the first slots, thus simplifying the emergency process and enabling even untrained personnel to quickly complete the release of the escape slide 2.

[0058] In an embodiment of the present invention, the inflation mechanism includes:

[0059] The compressed gas cylinder 10 is arranged on the expansion ring 5 at the outlet end of the escape slideway 2. The compressed gas cylinder 10 is communicated with the buffer air cushion 4 through an ejector 11 and an inflation valve 12;

[0060] The cover plate 13 is rotatably arranged at the outlet end of the accommodation box 1 through a hinge 14. A second clamping groove is formed on the cover plate 13;

[0061] The second buckle 15 is fixedly connected to the control link 6. The second buckle 15 is used for clamping with the second clamping groove;

[0062] The first plug pin 16 is arranged on the cover plate 13. The first plug pin 16 is used for plugging into the air outlet of the compressed gas cylinder 10.

[0063] When the control link 6 rotates, first, the second buckle 15 is separated from the second clamping groove, so that the cover plate 13 flips to open the outlet end of the accommodation box 1. When the cover plate 13 flips, it drives the first plug pin 16 to disengage from the compressed gas cylinder 10, so as to quickly inflate and deploy the buffer air cushion 4 through the ejector 11 and the inflation valve 12.

[0064] Furthermore, in the initial state, the control link 6 extends several first buckles 9 and second buckles 15 to provide fixed points (the widths of several first buckles 9 and second buckles 15, or rather, the central angle of the control link 6 corresponding to them, increase proportionally with the increase of the distance from the cover plate 13). After the device is enabled, by rotating the rotating grip 8, several first buckles 9 and second buckles 15 will be disengaged one by one, achieving the effect of releasing from the cover plate 13 to each expansion ring 5 one by one, and avoiding entanglement and blockage caused by instantaneous release.

[0065] In an embodiment of the present invention, a support plate 17 is arranged at the outlet end of the accommodation box 1. The support plate 17 is used for supporting the cover plate 13.

[0066] The support plate 17 can limit the flipping angle of the cover plate 13 and cooperate with the accommodation box 1 to form an inclined landslide structure.

[0067] In an embodiment of the present invention, after the buffer air cushion 4 is deployed, it can form a steering air cushion area 401 and a deceleration air cushion area 402. The steering air cushion area 401 is located between the escape slideway 2 and the deceleration air cushion area 402.

[0068] The steering air cushion area 401 is used for guiding the protective stretcher 3 to change from an inclined state to a horizontal state.

[0069] The deceleration air cushion area 402 is provided with a plurality of protrusions to enhance the deceleration effect.

[0070] In an embodiment of the present invention, after the escape slide 2 is deployed, it can form an inclined escape area 201 and a vertical escape area 202, and the vertical escape area 202 is located between the inclined escape area 201 and the buffer air cushion 4.

[0071] In an embodiment of the present invention, a flip door 18 is provided at the inlet end of the accommodation box 1, and a second bolt is provided on the flip door 18, and the second bolt is inserted into the side wall of the accommodation box 1.

[0072] After pulling out the second bolt and opening the flip door 18 after an emergency occurs, the escape slide 2 can be activated by operation.

[0073] In an embodiment of the present invention, a preparation board 22 is detachably connected to the inlet end of the accommodation box 1 through a limit block 20 and a fixed buckle 21, and the preparation board 22 is used to place the protective stretcher 3.

[0074] The preparation board 22 is a detachable structure to solve the daily space. It can be installed outside the flip door 18 for a long time, or inserted into the accommodation box 1 when an emergency occurs and locked in position through the limit block 20 and the fixed buckle 21 in the card slot below the flip door 18.

[0075] In an embodiment of the present invention, the accommodation box 1 includes an inclined bottom plate and a housing covering the bottom plate, and the bottom plate is connected to the building wall through a support rod.

[0076] In an embodiment of the present invention, the protective stretcher 3 includes a frame body 301, a five-point seat belt 302 provided on the frame body 301, and a plurality of protective air bags 303 provided on the frame body 301.

[0077] Protective air bags 303 are added at both ends of the frame body 301, and a five-point seat belt 302 is added in the middle. The protective air bags 303 are used to prevent the elderly from directly colliding with structures such as the bottom plate, the expansion ring 5, and the buffer air cushion 4 during the use of the escape slide 2, and directly rubbing against the inner wall of the escape slide 2 to avoid skin damage. The protective air bags 303 should also adopt a rapid inflation design, and a gas cylinder is used in combination with an ejector to achieve rapid and efficient inflation. The five-point seat belt 302 is used to completely fix the disabled elderly to prevent people from slipping off the stretcher during the use of the evacuation slide and losing protection.

[0078] The control link 6 is fully opened after rotating 180°, and all the expansion rings 5 are released. During this period, the inflation of the buffer air cushion 4 is also completed through the high-pressure and high-speed gas ejection effect. At this time, the evacuation slide can be used for evacuation. At this moment, the first expansion ring 5 is located at the entrance position of the accommodation box 1, and its width should be slightly larger than the diameter of the buffer air cushion 4 and the width of the protective stretcher 3 to provide a loose slide entrance. The second expansion ring 5 is exactly located at the end of the opened rear cover plate 13 to prevent the escape slide 2 from closing under the action of gravity here, and combines with the first expansion ring to form an initial inclined escape area 201 as a transition section of the escape slide 2. After leaving the escape slide 2, the protective stretcher 3 is first rotated to the horizontal state under the guidance of the steering air cushion area 401, and then enters the deceleration air cushion area 402 to gradually decelerate and stop, waiting for the ground support personnel to assist in the handling to complete the entire escape process.

[0079] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0080] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
