Description

Technical Field

[0001] This invention belongs to the field of elevator technology, specifically, it relates to an integrated structure for the decorative top of an elevator car. Background Technology

[0002] As a means of transporting passengers in high-rise buildings, elevators are bound to malfunction. If there are no passengers in the elevator, the elevator can resume normal operation after the maintenance personnel resolve the issue. However, if there are passengers trapped inside the elevator car when a malfunction occurs, the passengers need to be rescued as quickly as possible to avoid more serious consequences.

[0003] Currently, when an elevator malfunctions and cannot move to a nearby floor, passenger rescue is often carried out using the safety window on the car top. However, passenger elevators typically have a decorative ceiling structure for aesthetic purposes; this structure, located below the elevator car top, is used to decorate the car's ceiling. Rescue operations require opening both the safety window and the decorative ceiling structure to extricate the passengers. Therefore, quickly and conveniently opening a safety passage from outside the car to inside becomes crucial for rapid rescue.

[0004] For aesthetic purposes, elevator ceiling decorations often feature a layered metal frame structure, complemented by non-metallic materials such as translucent panels and various lighting fixtures. When an elevator malfunctions and rescue is required via the car's safety window, it's typically necessary to open the safety passage cover from inside the car before opening the safety window. However, due to limitations in lighting fixtures and structure, trapped passengers may not be able to open the safety passage cover from inside the car, and opening it through a small safety window from outside the car can also be extremely difficult. In such cases, the rescue operation will be delayed.

[0005] While some car roofs allow for externally opening safety access covers, structural limitations still present certain safety hazards and do not completely solve the problem of rapid rescue. For example... Figure 1 The decorative ceiling structure in the middle has the following problems:

[0006] (1) Below the car top 1 is the decorative top 2. The safety passage cover 3 is fixed to the decorative top 2 by the pin assembly 4. However, the pin assembly 4 can be touched inside the car, which can easily cause misoperation.

[0007] (2) Each safety passage cover 3 is fixed by two pin assemblies. The pin assemblies are located on both sides of the safety passage cover 3 and are controlled separately. In this case, if you want to open the safety passage cover 3 by moving the safety passage opening lever 15 from the outside of the car, you need to operate the safety passage opening lever 15 separately to open the safety passage cover 3. Therefore, it is impossible to open quickly.

[0008] (3) The safety passage opening lever 15 extends from the outside of the car and is fixed on the latch assembly. Due to its large length, it is difficult to move the opening lever outside the car, and sometimes it may even get stuck, which delays the rescue. Summary of the Invention

[0009] To address the above problems, this application provides an integrated structure for the decorative ceiling of an elevator car top, comprising:

[0010] Car roof;

[0011] The decorative roof includes a decorative roof frame, a safety passage cover, and a safety passage opening mechanism. The decorative roof frame is connected to the lower end of the car roof and includes an outer frame and a cover mounting frame connected within the outer frame.

[0012] A pair of safety passage covers are installed longitudinally within a cover mounting frame. A locking plate is provided on the inner side of each safety passage cover. The safety passage opening mechanism is mounted on the cover mounting frame and located between the pair of safety passage covers.

[0013] The safety passage opening mechanism includes a locking mechanism and a pair of symmetrically arranged lever mechanisms. The locking mechanism, in conjunction with the corresponding lever mechanisms, unlocks the safety passage opening mechanism.

[0014] Optionally, the locking mechanism is a triangular lock mechanism. Each locking mechanism includes a latch that cooperates with the corresponding lock plate. By rotating the triangular lock mechanism clockwise, one locking mechanism drives the latch to open one safety passage cover. By rotating the triangular lock mechanism counterclockwise, another locking mechanism drives the latch to open another safety passage cover.

[0015] Optionally, the safety passage opening mechanism further includes a support plate, the two ends of which are respectively fixed to the lateral ends of the cover plate mounting frame, and any locking mechanism satisfies:

[0016] The device includes a safety exit opening lever, a bracket, a connecting rod, a pull rod, and an elastic element. At least one bracket is installed laterally at intervals on the support plate. The bracket is cylindrical, and a connecting rod passes through each bracket laterally. An elastic element is sleeved on the rod body inside the bracket. A locking tongue is fixed to one end of the connecting rod extending out of the bracket, and the other end of the connecting rod is connected to the lateral pull rod.

[0017] The safety passage opening lever is installed at the end of the pull rod, and the triangular locking mechanism is installed on the support plate. The output end of the triangular locking mechanism is fixedly connected to a longitudinal pull bar, and the two ends of the pull bar respectively contact the rod body extending from the surface of the pull rod of the safety passage opening lever.

[0018] Optionally, a waist-shaped hole is provided on the car top along the lateral direction, and the upper end of the safety passage opening lever extends upward out of the waist-shaped hole.

[0019] Optionally, both ends of the pull bar contact the rod body extending from the lower surface of the safety passage opening lever.

[0020] Optionally, the locking port of the triangular lock mechanism is located inside the car.

[0021] Optionally, the pull rod is installed on the upper end of the bracket, and a groove is provided on the upper end of the bracket, in which the pull rod is slidably installed laterally.

[0022] Optionally, a safety window is also provided at the top of the car roof, which is used to close the safety passage corresponding to one of the safety passage cover plates.

[0023] Optionally, hinges are provided at both ends of the cover plate mounting frame, and the outer side of the safety passage cover plate is mounted on the cover plate mounting frame via the hinges.

[0024] Optionally, a decorative surface may be provided in the area outside the cover plate mounting frame.

[0025] In existing technologies, elevator decorative ceilings, for aesthetic purposes, are mostly integral metal frame structures supplemented with non-metallic materials such as translucent and color-changing materials. When an elevator malfunctions and rescue is required via the car roof safety window, it is usually necessary to open the safety passage cover from inside the car first, and then open the safety window. However, due to limitations such as lighting fixtures and structure, trapped passengers inside the elevator may not be able to open the safety passage cover from inside the car, and opening the safety passage cover from outside the car through the small safety window is also very difficult. This application allows for the simple and quick opening of the safety passage cover from outside the car using a safety passage opening lever, creating a safety passage for rescue, preventing passengers from being trapped in the elevator for extended periods, and reducing risks.

[0026] Furthermore, the horizontal sliding opening method of this application can effectively prevent the safety passage cover from being opened due to accidental operation from top to bottom, such as stepping or parts falling.

[0027] Furthermore, this application also allows the engagement of two locking tongues and locking plates to be controlled within the car via a triangular locking mechanism, enabling the opening of a safety passage cover with just one operation. Attached Figure Description

Detailed Implementation

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 2 to 3 As shown, the integrated structure of the elevator car top decorative top in this embodiment includes a car top 1 and a decorative top 2 connected below the car top 1. The decorative top 2 includes a safety passage cover 3, a safety passage opening mechanism 14, and a decorative top frame 5. The decorative top frame 5 is connected to the lower surface of the car top 1 and includes a square outer frame 51 and a cover plate mounting frame 50 connected within the outer frame 51. A decorative surface 52 is provided in the area outside the cover plate mounting frame 50, and the decorative surface 52 can be flush with the safety passage cover 3 when it is in the closed state.

[0037] A pair of safety passage covers 3 are respectively installed within the cover mounting frame 50 via hinges 53, allowing them to open downwards. Specifically, hinges 53 are provided at both longitudinal ends of the cover mounting frame 50, and the outer sides of the safety passage covers 3 are installed on the cover mounting frame 50 via hinges, allowing the inner sides of the pair of safety passage covers 3 to open or close the safety passage. A locking plate 8 is provided on the inner side of the safety passage cover 3, and the locking plate 8 has a notch (not shown) that cooperates with the locking tongue 11, thereby opening and closing the safety passage cover 3.

[0038] The safety passage opening mechanism 14 is installed between a pair of safety passage covers 3 and is used to control the opening of the pair of safety passage covers 3 respectively.

[0039] like Figure 3 As shown, the safety passage opening mechanism 14 includes a pair of symmetrically arranged locking mechanisms, a support plate 12 and a triangular lock mechanism 13. The two ends of the support plate 12 are respectively fixed to the two transverse ends of the cover plate mounting frame 50. The locking mechanisms have the same structure, and only one of them will be used as an example for explanation below.

[0040] like Figures 3 to 4 In the middle, the locking mechanism includes a safety passage opening lever 15, brackets 7, a pull rod 9, an elastic element 10, and a locking tongue 11. Multiple brackets 7 are installed at intervals on the support plate 12 along the length direction (i.e., laterally). Figure 3 One of the locking mechanisms employs two supports 7, each support 7 being cylindrical, preferably square-shaped, with through holes 71 on a pair of opposite side walls. Each support 7 has a connecting rod 72 that passes through the two through holes 71. An elastic element 10 is fitted onto the rod body within the square-shaped support 72. A locking tongue 11 is fixed to one end of the connecting rod 72 extending out of the support 7, for engaging with the locking plate 8 of the safety passage cover 3. When the locking tongue 11 is inserted into the locking plate 8, the safety passage cover 3 closes; when the locking tongue 11 is disengaged from the locking plate 8, the safety passage cover 3 opens. The elastic element 10 can be, for example, a spring.

[0041] The connecting rod 72 extends out of the bracket 7 and is connected to the pull rod 9. By pulling the pull rod 9 laterally, the latch 11 can be disengaged from the locking plate 8, thereby opening the safety passage cover 3. Furthermore, due to the action of the elastic element 10, after the latch 11 is pulled away from the locking plate 8 and the safety passage cover 3 is opened, the latch 11 will automatically reset under the force of the elastic element, preparing for the next locking of the latch and the locking plate.

[0042] The pull rod 9 is installed on the upper end of the bracket 7, and preferably, a groove with the same width as the pull rod 9 can be provided on the upper end of the bracket 7. The pull rod 9 is installed in the groove to restrict the pull rod 9 to move only along the length direction of the support plate 12.

[0043] The safety passage opening lever 15 is installed at the end of the pull rod 9, and its upper end extends upward out of the transverse waist-shaped hole 21 on the car roof 1, thereby allowing the safety passage opening lever 15 to be moved transversely to open the safety passage cover 3.

[0044] The lower end of the safety passage opening lever 15 extends from the lower surface of the pull rod 9. The triangular lock mechanism 13 is mounted on the support plate 12, for example, at the middle position in the width direction. The triangular lock opening can be located inside the car, allowing for easy opening of the triangular lock with a triangular key from inside the car. A pull bar 131 is fixedly connected to the output end of the triangular lock mechanism 13. The two ends of the pull bar 131 are respectively in contact with the rod body of the safety passage opening lever 15 below the lower surface of the pull rod 9. By rotating the triangular lock mechanism 13 clockwise or counterclockwise, the pull rods 9 on both sides can be driven to move linearly, simultaneously causing the latch 11 to disengage from the lock plate 8, thereby opening the safety passage cover 3. For example, if the triangular lock mechanism 13 is rotated clockwise, one end of the pull bar 131 pushes the pull rod 9 on that side to move laterally, thereby opening the safety passage cover 3 on that side, while the safety passage cover 3 on the other side remains closed. When the triangular locking mechanism 13 rotates counterclockwise, the other end of the pull bar 131 pushes the pull rod 9 on the other side to move laterally, thereby opening the safety passage cover 3 on the other side.

[0045] A safety window 20 is also provided at the upper end of the elevator car top 1. The safety window 20 is installed on the elevator car top 1 via hinges and is used to cover one of the safety passages of the elevator car top 1. It can be opened upwards. After the safety window and the safety passage cover plate 3 below it are opened, the safety passage can be opened. It should be noted that although there are two safety passage cover plates 3, only one is opened in use. The position of the safety window 20 above it determines which safety passage cover plate 3 is opened.

[0046] The integrated structure of the elevator car top decorative ceiling in this embodiment allows the safety passage cover 3 to be opened on the car top, forming a safety passage. For example, when rescuers reach the upper part of the car top and need to open the rescue passage, they first open the safety window 20, and then move the safety passage opening lever 15 on the car top 1. This causes the safety passage opening lever 15 to push the pull rod 9, which in turn drives the locking tongue 11. The locking tongue 11 then disengages from the locking plate 8, opening the safety passage cover 3 below the safety window 20. At this point, the safety passage is formed, allowing for rescue. Due to the linkage of the pull rod mechanism, the safety passage cover 3 can be opened by simply moving the safety passage opening lever 15 once.

[0047] For example, when it is necessary to open the safety passage cover in the car, the triangular lock mechanism 13 can be rotated clockwise, which will drive the pull rod 9, which will drive the locking tongue 11. Then the locking tongue 11 will disengage from the locking plate 8, opening the safety passage cover 3 on one side. Alternatively, the triangular lock mechanism 13 can be rotated counterclockwise, which will drive the pull rod 9, which will drive the locking tongue 11. Then the locking tongue 11 will disengage from the locking plate 8, opening the safety passage cover 3 on the other side.

[0048] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications are all within the protection scope of the claims of the present invention.
