Description

Technical Field

[0001] This utility model belongs to the field of elevator safety window technology, specifically relating to a four-fold safety window for a gantry-type car. Background Technology

[0002] Elevator cars have emergency exits located on the top of the car. During normal operation, these exits are sealed with safety windows. In the event of an accident, passengers trapped inside can open the safety windows and escape through the exit. However, most safety windows in current elevator cars are currently integrated units. This can be problematic when the car is shallow or the top floor is low. Figure 1 As shown, when the integrated safety window 1 is opened, it may be blocked by components above the car roof panel 2, such as the upper beam or lifting mechanism. Therefore, in reality, safety window 1 cannot be fully opened, resulting in insufficient opening and making it difficult for people to climb out of the car. Furthermore, there is a risk that the safety window may fall down and injure people, increasing the overall danger.

[0003] In view of the aforementioned existing technology, it is necessary to make reasonable improvements to the existing safety window structure for car use. To this end, the applicant has made beneficial designs, and the technical solution described below arises from this background. Utility Model Content

[0004] The objective of this invention is to provide a four-fold safety window for a gantry-type car, which can achieve four-fold folding, opens to a lower height than normal, saves space, solves the interference problem, and is easy to process and manufacture.

[0005] The present invention accomplishes its objective as follows: a four-fold safety window for a gantry-type car is installed at the window position on the car roof panel on the upper side of the car. The safety window comprises four separate window units: a first window unit, a second window unit, a third window unit, and a fourth window unit, which are sequentially connected by hinges. The end of the fourth window unit furthest from the third window unit is rotatably connected to the car roof panel via a hinge. The first window unit cooperates with a switch baffle fixed to the car roof panel. A rotary latch is installed on the main body of the first window unit. When the rotary latch rotates into or out of the intersecting lock hole on both the first window unit and the switch baffle, the rotary latch stops or releases the first window unit from opening upwards.

[0006] In a specific embodiment of this utility model, the hinges for connecting the second window and the third window, as well as the hinges for connecting the fourth window and the car roof, are all installed on the outside of the car, i.e. above the car roof.

[0007] In another specific embodiment of this utility model, the hinges for connecting the first window and the second window, as well as the hinges for connecting the third window and the fourth window, are all installed on the inner side of the car, that is, below the car roof.

[0008] In another specific embodiment of this utility model, the connecting ends of the first window, the second window, the third window and the fourth window are all bent.

[0009] In another specific embodiment of this utility model, the first window, the second window, and the third window are all bent into a "[" shape or a right-angle shape.

[0010] In another specific embodiment of this utility model, the rotating tongue lock includes a lock seat and a tongue plate. The lock seat is installed on the mounting hole of the first window body. One end of the lock seat extends into the car and a rotating operating component is provided at that end. The other end of the lock seat is located outside the car and a tongue plate is fixedly installed at that end. Rotating the rotating operating component can enable the tongue plate to be rotated into or out of the lock hole through which the first window body connection end and the switch baffle pass.

[0011] In a further specific embodiment of this utility model, the end of the lock seat that extends into the car is provided with a keyhole for key insertion. Under normal circumstances, the rotating operating component is locked. When a key is inserted into the keyhole to unlock, rotating the rotating operating component can realize the screw plate being screwed in and out.

[0012] The present invention, due to the adoption of the above-mentioned structure, has the following beneficial effects: First, the safety window described in this technical solution is composed of a window body made of four sheet metal parts, a hinge connecting the two window bodies in pairs, and a set of rotary latches, which can achieve four-fold folding. The opening height is lower than that of normal windows, saving space and solving the problem of interference with the components above the car. Second, the safety window can close off larger safety exits, that is, the size of each window can be changed to meet different safety exit size requirements. Third, the rotary latches used are easy to replace after long-term use due to aging. The entire safety window is simple to process and manufacture, and the opening operation is also simple in an emergency, helping to achieve rapid evacuation. Attached Figure Description

[0015] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, the applicant's description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes based on the concept of this utility model should be considered within the scope of protection of this utility model.

[0016] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the positions shown in the corresponding figures, and therefore should not be construed as a special limitation on the technical solution provided by this utility model.

[0017] Please see Figures 2 to 6 This utility model relates to a four-fold safety window for a gantry-type car, which is... Figure 2 The safety window 1 is installed at the window of the car roof panel 2 on the upper side of the car. Specifically, it includes four foldable individual windows, namely the first window 11, the second window 12, the third window 13, and the fourth window 14, which are connected together in sequence by hinges 3. One side of the fourth window 14 is rotatably connected to the car roof panel 2 by hinges 3, and the other side of the fourth window 14 is rotatably connected to one side of the third window 13 by hinges 3. The other side of the third window 13 is rotatably connected to one side of the second window 12 by hinges 3, and the other side of the second window 12 is rotatably connected to one side of the first window 11 by hinges 3. The other side of the first window 11 cooperates with the switch baffle 4 fixed on the car roof panel 2.

[0018] The hinges 3 used to connect the second window 12 and the third window 13, and the hinges 3 used to connect the fourth window 14 and the car roof 2, are all installed on the outside of the car, above the car roof 2. Figure 5 As shown, the fourth window 14 is flipped outward relative to the car roof panel 2, and the second window 12 is flipped outward relative to the third window 13.

[0019] The hinges 3 used to connect the first window 11 and the second window 12, as well as the hinges 3 used to connect the third window 13 and the fourth window 14, are all installed on the inside of the car, that is, below the car roof 2. Figure 5 As shown, the first window 11 is flipped inward relative to the second window 12, and the third window 13 is flipped inward relative to the fourth window 14.

[0020] like Figure 5As shown, the connecting ends of the first window 11, the second window 12, the third window 13, and the fourth window 14 are all bent to enhance the strength of the window connection. Specifically, they can be bent into a "[" shape or a right angle shape. In this embodiment, the connecting ends of the first window 11, the second window 12, and the third window 13 are all bent into a "[" shape or a right angle shape, while one end of the fourth window 14 is bent, and the other end is not bent.

[0021] like Figure 2 , Figure 5 As shown, a rotary latch 5 is installed on the main body plate of the first window 11. When the rotary latch 5 rotates and inserts into the lock hole through which the connecting end of the first window 11 and the switch baffle 4 pass, the rotary latch 5 stops the first window 11 from opening upward.

[0022] The rotary latch 5 includes a lock base 51 and a latch plate 52. The lock base 51 is installed on the mounting hole of the first window 11. One end of the lock base 51 extends into the car and has a rotary operating component 511 at that end. The other end of the lock base 51 is located outside the car and has the latch plate 52 fixedly installed at that end. Rotating the rotary operating component 511 allows the latch plate 52 to be screwed into or out of the lock hole that connects the bent end of the first window 11 and the switch baffle 4. Furthermore, the end of the lock base 51 extending into the car has a keyhole 512 for inserting a key. Under normal circumstances, the rotary operating component 511 is locked and cannot be rotated. The rotary operating component 511 can only be operated when a key is inserted into the keyhole 512 to unlock it. Alternatively, the key itself can be the rotary operating component 511, and rotating the key allows the latch plate 52 to be screwed in and out.

[0023] Please continue reading. Figure 5 and Figure 6 The operation process of the four-fold safety window of the gantry-type car described in this utility model is as follows: First, use the key to open the rotary latch 5, so that the rotary latch 5 can be rotated, and the latch plate 52 can be rotated out of the lock hole through which the first window 11 bend and the switch baffle 4 pass.

[0024] Next, push the connection between the first window 11 and the second window 12 to fold the two windows upwards.

[0025] Next, push the connection between the third window 13 and the fourth window 14 to fold the two windows upwards.

[0026] Then, rotate the hinge 3 between the second window 12 and the third window 13 to fold all the windows together.

[0027] Finally, rotate the hinge 3 between the fourth window 14 and the car roof 2 to open the safety window and make way for the safety exit.

[0028] When the safety window is folded, its height h is reduced by about half compared to the height H of a non-foldable safety window when it is open, which can effectively prevent interference between the safety window and the components above when it is open.
