Description

Technical Field

[0001] This invention relates to the field of escape door and window technology, and more specifically, to an automatic opening system for escape doors and windows. Background Technology

[0002] In the existing field of building safety, escape doors and windows serve as key evacuation routes in emergency scenarios such as fires and earthquakes, and their ease of opening and reliability are directly related to the safety of people's lives.

[0003] Traditional escape doors and windows rely on conventional locks and handles to open. In emergencies, people may panic and not be able to find the unlocking point, or the lock may become stuck due to high temperature or deformation, making it difficult to open quickly.

[0004] Although some doors and windows have been equipped with emergency opening mechanisms, they are mostly of a single type, such as an emergency lock only installed on one side of the door panel. This is not only cumbersome to operate, but also not user-friendly for the elderly, children and other people with mobility difficulties, making it difficult to quickly complete the opening action.

[0005] Meanwhile, most escape doors and windows lack adjustable observation and ventilation structures, making it difficult for people to observe the external fire and smoke conditions in advance during emergencies. Blindly opening the door can easily lead to danger. Summary of the Invention

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides an automatic opening system for escape doors and windows, so as to solve the technical problems mentioned in the background art that it is difficult to quickly complete the opening action and difficult to observe the external fire and smoke conditions in advance.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: An automatic opening system for escape doors and windows includes a door panel with a door frame on its outer side. A handle is provided on one side of the door panel and the door frame. An emergency door is located at the lower end of the door panel and is connected to the door panel via a hinge. A fixing groove is provided on the other side of the emergency door, and a slider is installed within the fixing groove. Two sets of symmetrically arranged springs are installed between the slider and the side wall of the fixing groove. A locking rod is located at the center of the slider, passing through and slidably connected to the fixing groove. A lock hole is provided on the side of the door panel near the fixing groove, and the locking rod passes through and slidably connects to the lock hole. A hand-held block is provided on one side of the slider, and an escape window assembly is located at the upper end of one side of the door panel.

[0008] The invention is further configured such that the escape window assembly includes a transparent window, a sliding rail, a sliding strip, and a latch. An opening is provided on the door panel, and a groove is provided on one side of the opening. The transparent window is adapted to and slidably connected to both the opening and the groove. The sliding strip is symmetrically arranged on the upper and lower side walls of the transparent window. The sliding rail is symmetrically arranged on the upper and lower side walls of the opening and the groove. The sliding strip passes through the sliding rail and is slidably connected to it. A fixing plate is provided on the side of the opening near the groove, and a fixing hole is provided on the fixing plate. Multiple sets of evenly distributed sliding holes are provided at the lower end of the transparent window. The fixing hole and the sliding hole can overlap. The latch passes through the fixing hole and the sliding hole, allowing for flexible adjustment of the opening range and locking, adapting to different needs such as observation, ventilation, or escape.

[0009] The invention is further configured such that symmetrical mounting plates are provided at both ends of the spring, and screws are provided at the four corners of the mounting plates. The screws pass through the mounting plates, the fixing grooves, and the sliders, so that the spring can be installed and disassembled securely and conveniently, and the spring can be prevented from shifting or falling off.

[0010] The present invention is further configured such that the sidewall of the transparent window is provided with symmetrical push-pull handles, which facilitates the use of both hands to easily push the transparent window to slide.

[0011] The invention is further configured such that a protective plate is provided on the front side wall of the fixing groove, and the protective plate is detachably connected to the fixing groove, which facilitates later maintenance and does not affect quick operation in emergency situations.

[0012] The invention is further configured such that the surface of the protective plate is provided with an emergency activation mark, the mark being coated with a fluorescent coating, which is conspicuous in emergency situations and quickly indicates the location of the protective plate.

[0013] The present invention is further configured such that a sealing strip is provided between the door panel and the door frame to enhance the sealing performance between the door panel and the door frame and prevent external smoke, rainwater or dust from entering.

[0014] The present invention is further configured such that an anti-corrosion layer is provided on the surface of the door panel, the anti-corrosion coating comprising the following components: 54.5-68.1% resin, 9.5-14.8% curing agent, 10-15% self-made titanium-molybdenum alloy nanopowder, 10-15% self-made modified wear-resistant and anti-friction filler, and 0.5-0.8% additives; the percentages are by mass. (III) Beneficial Effects Compared with the prior art, the present invention provides an automatic opening system for escape doors and windows, which has the following advantages: 1. In terms of the core needs of emergency evacuation, the emergency door at the bottom of the door panel can be opened and closed flexibly through the hinge. When locked, the slider drives the locking rod to insert into the lock hole. Two sets of symmetrical springs provide stable elasticity for locking, ensuring that the emergency door is firmly closed under normal conditions. In an emergency, simply pull the hand block to drive the slider to compress the spring, so that the locking rod is disengaged from the lock hole and the emergency door can be opened quickly. It is especially suitable for the rapid evacuation of the elderly, children and other people with mobility difficulties or when carrying items.

[0015] 2. The escape window assembly at the top of the door panel forms a supplementary evacuation channel. The transparent window can be slid along the slide rail on the upper and lower sides to precisely control the opening size. It can be opened slightly when only observing the external fire situation is needed, and the opening can be increased when ventilation or evacuation is required. The sliding process is smooth and not easy to jam. By inserting a pin through the fixing hole of the fixing plate and the different sliding holes of the transparent window, the transparent window can be stably locked in the target opening position to prevent the window from moving randomly during evacuation and affecting passage.

[0016] 3. The device combines sealing and protection performance. The sealing design of the door panel and door frame can effectively block the intrusion of external rainwater, dust and smoke, making it cleaner for daily use and reducing the risk of toxic fumes entering in emergencies.

[0022] Please see Figure 1-5 An automatic opening system for escape doors and windows includes a door panel 1, a door frame 2 on the outer side of the door panel 1, a switch handle 3 on one side of the door panel 1 and the door frame 2, an emergency door 4 at the lower end of the door panel 1, the emergency door 4 being connected to the door panel 1 by a hinge 5, a fixing groove on the other side of the emergency door 4, a slider 6 within the fixing groove, two sets of symmetrically arranged springs 7 between the slider 6 and the side wall of the fixing groove, a locking rod 8 at the center of the slider 6, the locking rod 8 passing through the fixing groove and slidably connected thereto, a lock hole 9 on the side of the door panel 1 near the fixing groove, the locking rod 8 passing through the lock hole 9 and slidably connected thereto, a hand-held block 10 on one side of the slider 6, and an escape window assembly on the upper end of one side of the door panel 1.

[0023] The escape window assembly includes a transparent window 11, a sliding rail 12, a sliding strip 13, and a latch 14. The door panel 1 has an opening, and a groove is provided on one side of the opening. The transparent window 11 is adapted to and slidably connected to the opening and the groove. The sliding strip 13 is symmetrically arranged on the upper and lower side walls of the transparent window 11. The sliding rail 12 is symmetrically arranged on the upper and lower side walls of the opening and the groove. The sliding strip 13 passes through the sliding rail 12 and is slidably connected to it. A fixing plate 15 is provided on the side of the opening near the groove. The fixing plate 15 has fixing holes. The lower end of the transparent window 11 has multiple sets of evenly distributed sliding holes. The fixing holes and the sliding holes can coincide. The latch 14 passes through the fixing holes and the sliding holes.

[0024] The transparent window 11 has symmetrical push-pull handles 18 on its side wall. In this embodiment, under normal conditions, the door panel 1 is locked to the door frame 2 by the switch handle 3, and the emergency door 4 is in a closed state. The two sets of symmetrical springs 7 in the fixing groove remain naturally extended. Pushing the slider 6 causes the locking rod 8 to pass through the lock hole 9, thus firmly locking the emergency door 4. The transparent window 11 of the escape window assembly is embedded in the opening of the door panel 1. The pin 14 passes through the fixing hole of the fixing plate 15 and the sliding hole of the transparent window 11, so that the transparent window 11 is stably closed without affecting indoor lighting and sealing. When it is necessary to observe the external situation or to ventilate slightly, pull out the pin 14 of the escape window, hold the symmetrical push-pull handles 18 on the side wall of the transparent window 11 with both hands, and push the transparent window 11 to slide along the upper and lower sliding strips 13 and the sliding rails 12. The sliding strips 13 move smoothly in the sliding rails 12, causing the transparent window 11 to slide towards the groove. Control the opening size according to the needs. After adjusting to the appropriate position, re-pass the pin 14 through the corresponding fixing hole and sliding hole to lock the transparent window 11.

[0025] More specifically, in case of an emergency requiring evacuation through emergency door 4, the operator holds the handle 10 of emergency door 4 and pulls it outward, causing slider 6 to compress spring 7 in the fixing groove. Simultaneously, slider 6 causes locking rod 8 to disengage from lock hole 9 of door panel 1. After unlocking, emergency door 4 opens by rotating around door panel 1 via hinge 5, allowing personnel to quickly evacuate through emergency door 4. After evacuation, push emergency door 4 to close, slider 6 resets under the elastic force of spring 7, causing locking rod 8 to re-insert into lock hole 9, completing the locking of emergency door 4. If evacuation through escape window is required, pull out bolt 14 and push transparent window 11 along slide rail 12 to the maximum opening range to ensure unobstructed evacuation passage. After personnel evacuate, push transparent window 11 to reset and insert bolt 14 to lock. In daily use, if door panel 1 needs to be fully opened, turn switch handle 3 to unlock door panel 1 and door frame 2, achieving full door opening.

[0026] Please see Figures 1-5 As one embodiment of the mounting plate 16: symmetrical mounting plates 16 are provided at both ends of the spring 7, and screws 17 are provided at the four corners of the mounting plate 16. The screws 17 pass through the mounting plate 16, the fixing groove, and the slider 6. A protective plate 19 is provided on the front side wall of the fixing groove, and the protective plate 19 is detachably connected to the fixing groove.

[0027] Specifically, the removable protective plate 19 on the front and side walls of the fixed groove provides protection for the internal structure.

[0028] Please see Figures 1-5 As one embodiment of the mark 20: the surface of the protective plate 19 is provided with an emergency opening mark 20, and the mark 20 is coated with a fluorescent coating.

[0029] Specifically, in emergency situations, the fluorescent marker 20 conspicuously indicates the location of the protective panel 19 in dim light or dense smoke.

[0030] Please see Figures 1-5 As one embodiment of the sealing strip: a sealing strip is provided between the door panel 1 and the door frame 2.

[0031] Specifically, the sealing strips between door panel 1 and door frame 2 are tightly fitted to ensure airtightness.

[0032] In summary, when using the overall equipment: During daily use, the entire unit is in a stable closed state. The door panel 1 is locked to the door frame 2 via the switch handle 3 on one side. The sealing strip between the door panel 1 and the door frame 2 is tightly fitted, which can effectively prevent external rainwater, dust and odors from entering the room, ensuring the airtightness and comfort of daily use.

[0033] At this time, the emergency door 4 at the lower end of the door panel 1 is also in a firmly locked state, and the escape window assembly at the upper end of the door panel 1 is also in a closed and locked state. The transparent window 11 is embedded in the opening of the door panel 1, and the pin 14 passes through the fixing hole of the fixing plate 15 on one side of the opening and the sliding hole at the lower end of the transparent window 11, so that the transparent window 11 is stably fixed and does not affect the indoor lighting.

[0034] When you need to open or close the doors and windows, simply operate the switch handle 3 on one side of the door panel 1 and the door frame 2 to easily unlock and lock them. The operation is convenient and in line with conventional usage habits.

[0035] If you need to observe the external environment or perform minor ventilation, there is no need to open the main door or emergency door 4. You can directly pull out the latch 14 of the escape window, hold the symmetrical push-pull handles 18 on the side wall of the transparent window 11 with both hands, and push the transparent window 11 to slide along the slide bars 13 and slide rails 12 on the upper and lower sides. The slide bars 13 move smoothly in the slide rails 12, causing the transparent window 11 to slide towards the groove on the opening side. Control the opening size according to the observation or ventilation needs. After adjusting to the appropriate position, re-thread the latch 14 through the corresponding fixing hole and sliding hole to lock the transparent window 11 stably in the target open state. After ventilation or observation, pull out the latch 14, push the transparent window 11 back to its original position, and then insert the latch 14 to lock it.

[0036] In case of emergencies such as fire or earthquake, if the main door cannot be opened normally by the switch handle 3 due to lock jamming or deformation, the emergency door 4 can be used for evacuation. At this time, even in a smoke-filled and dimly lit environment, the fluorescent coating marking 20 on the surface of the protective plate 19 can clearly indicate its location, and the operator can quickly find the handheld block 10.

[0037] Hold the hand block 10 and pull it away from the door panel 1. This will cause the slider 6 to compress the two sets of springs 7 in the fixing groove. Simultaneously, the slider 6 will cause the locking rod 8 to disengage from the lock hole 9 of the door panel 1, thus releasing the lock of the emergency door 4. Then push the emergency door 4. The emergency door 4 will open by rotating around the door panel 1 through the hinge 5, forming a clear evacuation passage for people to evacuate quickly.

[0038] If the emergency door 4 has insufficient opening space or requires auxiliary evacuation, the escape window assembly can also be operated at the same time. After pulling out the latch 14, push the transparent window 11 along the slide rail 12 to the maximum opening range to further expand the evacuation or ventilation space. After evacuation, the transparent window 11 and the latch 14 can be reset.

[0039] If spring 7 needs to be replaced, remove the protective plate 19, remove the screws 17, remove the old spring 7 and mounting plate 16, install the new spring 7 and mounting plate 16, fix it with screws 17, and finally install the protective plate 19.
