Description

Technical Field

[0001] This invention relates to the technical field of escape devices, and more particularly to a pop-out device for an escape railing on an escape window. Background Technology

[0002] An escape window is a window installed inside a building, usually located on a security grille, and has specific dimensions and opening mechanisms to provide an escape route in an emergency.

[0003] For example, Chinese patent application number 202310704057.9, entitled "A Glass Railing Hidden Escape Device," describes an escape device that "includes a railing frame and a glass block covering the railing frame. The railing frame and at least one glass block are connected by a locking structure, and the railing frame is connected to an escape railing via a wire-laying mechanism. The escape railing has a folded form and an unfolded form. The folded form is used for storage within the railing frame, and the unfolded form is used for escape." Existing escape railings are stored inside the storage cavity of the escape window. In the event of a fire, the escapee needs to unlock the escape window and then manually push the escape railing out of the storage cavity for it to unfold and be used for escape. However, every minute is crucial in a fire, and every minute saved in escaping makes the escapee safer. Existing escape railings have too many steps, significantly slowing down the escapee's escape time.

[0004] Existing escape windows all use a hinged lever as the support rod after the escape barrier is deployed. This lever needs to bear the combined weight of the escapee and the escape barrier. However, because the lever needs to be hinged to fit into the escape window, when the escape barrier is deployed, the hinge point of the lever almost has to bear the combined weight of the escapee and the escape barrier. This makes the hinge point of the lever prone to breaking due to the inability to withstand such a heavy weight. Since escape windows are used at heights, if the hinge point of the lever breaks, the escapee will be at risk of falling. Summary of the Invention

[0005] The purpose of this invention is to provide a pop-out device for an escape railing on an escape window.

[0006] To achieve the above objectives, the present invention adopts the following solution:

[0007] An escape window pop-out device includes a window frame, a storage cavity on the top crossbeam of the window frame, and symmetrically hinged swing rods within the storage cavity. The swing rods are hollow, and a hanging plate is provided within the storage cavity to hold the swing rods.

[0008] A triggering mechanism is provided between the storage cavity and the hanging plate, which can drive the hanging plate to pop out of the swing arm;

[0009] The swing arm consists of a fixed base and a rotating rod. The fixed base is symmetrically fixed to the top of the storage cavity, and the rotating rod is rotatably set at the bottom of the fixed base. A suspension rope assembly for connecting the escape rail is provided at the front end of the swing arm.

[0010] A reinforcing structure is provided on the inner wall of the storage cavity and at the front end of the rotating rod to increase the load-bearing capacity of the swing rod.

[0011] As a further embodiment of the present invention, the hanging plate includes a base plate symmetrically arranged between the swing rods within the storage cavity, a hanging plate in front of the base plate for hanging the swing rods, a storage spring between the base plate and the hanging plate, a C-shaped groove on one side of the hanging plate for hanging the swing rods, and screw holes at the four corners of the base plate.

[0012] As a further embodiment of the present invention, the triggering mechanism includes a first buckle fixed on the hanging plate, a second buckle fixed on the base plate that can cooperate with the first buckle, and a pull rope provided at the bottom of the second buckle.

[0013] As a further embodiment of the present invention, one end of the first buckle is provided with a first inclined surface, and one end of the second buckle is provided with a second inclined surface. The fastening end of the second buckle extends upward, and the fastening end of the first buckle extends downward. The second buckle is made of a material with elasticity and resilience. Through holes are symmetrically provided on both sides of the inner wall of the storage cavity. One end of the pull rope passes through the through hole and is fixed to the unfolding structure of the escape window.

[0014] As a further embodiment of the present invention, the fixing base includes a fixing shaft symmetrically fixed to the top of the storage cavity, a limiting plate fixed to the bottom of the fixing shaft, and a bearing sleeved on the fixing shaft.

[0015] As a further embodiment of the present invention, the fixed shaft is designed to be inclined, with one end of the fixed shaft extending inclinedly into the storage cavity.

[0016] As a further embodiment of the present invention, the rotating rod includes a rotating sleeve disposed at the bottom of the fixed shaft and covering the limiting plate and the bearing, and a load-bearing rod is fixed at the bottom of the rotating sleeve, the load-bearing rod being L-shaped.

[0017] As a further embodiment of the present invention, the suspension rope assembly includes a fixing plate fixed inside the storage cavity and located on one side of the fixing seat. A suspension rope is fixed on the fixing plate. A rotating shaft is provided at the front end of the load-bearing rod for lateral rotation. One end of the suspension rope passes through the fixing shaft, passes around the rotating shaft, and extends out of the load-bearing rod. The end of the suspension rope extending out of the load-bearing rod is connected to the escape barrier. Screw holes are provided on the fixing plate and the storage cavity. The fixing plate is fixed to the storage cavity by screws.

[0018] As a further embodiment of the present invention, the suspension rope assembly includes a fixing plate fixed inside the storage cavity and located on one side of the fixing seat. A suspension rope is fixed on the fixing plate. A rotating shaft is provided at the front end of the load-bearing rod for lateral rotation. One end of the suspension rope passes through the fixing shaft, passes around the rotating shaft, and extends out of the load-bearing rod. The end of the suspension rope extending out of the load-bearing rod is connected to the escape barrier. Screw holes are provided on the fixing plate and the storage cavity. The fixing plate is fixed to the storage cavity by screws.

[0019] As a further embodiment of the present invention, the reinforcing structure includes a first ring fixedly disposed at the bottom of the storage cavity at the front end of the fixed shaft, a second ring fixedly disposed at the front end of the load-bearing rod, and a steel rope connected between the first ring and the second ring.

[0020] In summary, the beneficial effects of the invention compared to the prior art are: when a fire occurs, as the escapee opens the escape window, the escape railing automatically pops out from the storage cavity inside the escape window under the action of the triggering mechanism. This eliminates the escapee's operation steps, greatly shortens the escape time, allows the escapee to get out of the fire more quickly, and improves the escapee's survival rate.

[0021] In the event of a fire, when the escape window is opened, the reinforcing structure between the inner wall of the storage cavity and the front end of the rotating rod will distribute part of the weight to the connection point between the fixed seat and the rotating rod on the swing rod. This prevents the total weight of the escape window and the escape window from being entirely applied to the connection point, thereby increasing the maximum weight the escape window can withstand and preventing the connection point from breaking and causing the escapee to fall. The fixed shaft on the swing rod is set at an angle, so when the escape window is opened, the rotating rod will automatically unfold under the weight of the swing rod itself. After the rotating rod is unfolded, it will not close on its own without external force and will remain in the unfolded state. Attached Figure Description

[0045] In use: In the event of a fire, the person escaping unlocks the escape window, opening it. Initially, the swing arm 3 is hooked into the mounting plate 4 and retracted into the storage cavity 2 of the window frame 1. The first latch 21 and the second latch 22 are engaged, and the storage spring 6 is compressed. One end of the pull rope 23 passes through the through hole 32 and is fixed to the escape window's unfolding structure 200. When a fire occurs, the person escaping unlocks the escape window, opening it. Simultaneously, the unfolding structure 200 on the escape window... When the escape window is fully opened by the unfolding structure 200, the pull rope 23 will be pulled, and the second buckle 22 will be deformed. After the second buckle 22 is deformed, the first buckle 21 will separate from the second buckle 22, and the storage spring 6 will be released. Under the action of the spring force of the storage spring 6, the swing arm 3 will be pushed to unfold, and at the same time, the escape rail will pop out of the escape window's storage cavity and unfold. This eliminates the escaper's operation steps and greatly shortens the escape time. Figure 2 and Figure 5 As shown in the figure, the fixed shaft 111 is designed with an inclination. One end of the fixed shaft 111 extends inward into the storage cavity 2. Therefore, when a fire occurs and the escape window is opened, the rotating rod 120 will automatically unfold along the axis of the fixed shaft 111 under its own weight. Because the front end of the rotating rod 120 is inclined downward after unfolding, it will not close on its own without external force and will remain in the unfolded state. This can prevent the escaper from accidentally closing the rotating rod 120 during escape. Because the fixed shaft 111 is designed with an inclination, the rotating rod 120 will also automatically unfold. This prevents the escape barrier from being accidentally opened during escape due to the rotating rod 120 not being fully unfolded. The reinforcing structure 140 can share part of the weight of the connection point between the fixed seat 110 and the rotating rod 120 after the escape barrier is fully unfolded, so that the total weight of the escaper and the escape barrier is not entirely applied to the connection point between the fixed seat 110 and the rotating rod 120.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the invention. Those skilled in the art should understand that the invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made without departing from the spirit and scope of the invention, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection of the invention is defined by the appended claims and their equivalents.
