Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to a protective device for an elevator door system. Background Technology

[0002] In elevator structural design, such as Figure 1 As shown, due to the vertical movement of the elevator car, a certain gap must be maintained between the car door sill and the landing door sill. The national standard specifies that the gap between the car door guard plate and the landing door guard plate should be less than 35mm. After leveling, a horizontal gap of less than 35mm will form between the car door sill and the landing door sill, and a lateral gap of less than 35mm will form on opposite sides of the car door sill and the landing door sill. When the elevator doors open to allow passengers to pass, small, thin items such as mobile phones and rings can easily fall through these gaps, causing property damage to passengers and posing a safety hazard to elevator operation. Summary of the Invention

[0003] To address the aforementioned technical problems, the purpose of this invention is to propose an elevator door system gap protection device that can reduce the horizontal and lateral gaps between the car door sill and the landing door sill, effectively preventing small items from falling, meeting the safety requirements of elevator use, and possessing strong practicality.

[0004] The technical solution of the present invention is implemented as follows: an elevator door system protection device, the elevator door system including an entrance / exit passage for entering and exiting an elevator car, a car door sill, and a landing door sill; a horizontal gap extending in the horizontal direction is formed between the car door sill and the landing door sill; and a lateral gap extending in the vertical direction is formed between the car door sill and the landing door sill on opposite sides of the entrance / exit passage; the protection device includes a first protection device and a second protection device; The first protective device is disposed between the car door sill and the landing door sill, and includes a first baffle and a first drive mechanism; the first baffle is movably arranged to have a first blocking position that partially or completely blocks the horizontal gap and a first open position away from the first blocking position; the first drive mechanism is used to drive the first baffle to move back and forth between the first blocking position and the first open position. The second protective device is arranged to correspond to the lateral gap; the second protective device is disposed between the car door sill and the landing door sill, and includes a second baffle and a second drive structure; the second baffle is movably arranged and has a second blocking position that at least partially or completely blocks the lateral gap and a second open position away from the second blocking position; the second drive mechanism is used to drive the second baffle to move back and forth between the second blocking position and the second open position.

[0005] Furthermore, both the first and second protection devices are installed on the elevator car.

[0006] Furthermore, the first baffle is disposed on the car door sill and rotates between a first blocked position and a first open position about a first central axis; the first central axis extends along the width direction of the car door sill.

[0007] Furthermore, the second baffle is disposed on the car door sill and rotates between a second blocked position and a second open position about a second central axis; the first central axis extends in the vertical direction.

[0008] Furthermore, when the elevator car door is closed, the first baffle moves to the first open position and the second baffle moves to the second open position; when the elevator car door is opened, the first baffle moves to the first blocking position and the second baffle moves to the second blocking position.

[0009] Furthermore, both the first drive mechanism and the second drive mechanism are cam-linkage mechanisms.

[0010] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: This invention utilizes the combined use of a first protective device and a second protective device. When the first baffle is in the first blocking position, it can block part or all of the horizontal gap, thereby reducing the horizontal gap. When the second baffle is in the second blocking position, it can block part or all of the lateral gap, thereby reducing the lateral gap. This combination of methods can reduce the horizontal and lateral gaps between the car door sill and the landing door sill, effectively preventing small items from falling and meeting the safety requirements of elevator use, demonstrating strong practicality.

[0012] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0013] like Figure 2-5 The diagram illustrates an elevator door system protection device according to this embodiment. This elevator door system is a conventional structure of the prior art, comprising an entrance / exit passage 5 for entering and exiting the elevator car, a car door sill 1, and a landing door sill 2. A horizontal gap extending in the horizontal direction is formed between the car door sill 1 and the landing door sill 2. Lateral gaps extending in the vertical direction are formed between the car door sill 1 and the landing door sill 2 on opposite sides of the entrance / exit passage 5.

[0014] The protective device in this embodiment includes a first protective device and a second protective device. Both the first and second protective devices are installed on the elevator car to move up and down with the car. The first protective device is installed on the car door sill 1 and includes a first baffle 3 and a first drive mechanism 31. The first baffle 3 is movably installed on the car door sill 1, having a first blocked position that partially or completely blocks the horizontal gap and a first open position away from the first blocked position. The first baffle 3 is mounted on the car door sill 1 via a hinge shaft, allowing it to rotate around a first central axis between the first blocked position and the first open position. The first central axis extends along the width direction of the car door sill 1. When in the first open position, the first baffle 3 extends vertically. The first drive mechanism 31 is drively connected to the first baffle 3 to drive the first baffle 3 back and forth between the first blocked position and the first open position. The first drive mechanism 31 is a prior art cam-linkage mechanism.

[0015] The aforementioned second protective device is arranged corresponding to each lateral clearance. This second protective device is arranged on the car door sill 1 and includes a second baffle 4 and a second drive mechanism. The second baffle 4 is movably arranged on the car door sill 1, having a second blocked position that at least partially or completely blocks the lateral clearance and a second open position away from the second blocked position. In a specific structural design, the second baffle 4 is mounted on the car door sill 1 via a hinge shaft, allowing it to rotate about a second central axis between the second blocked position and the second open position. The aforementioned first central axis extends vertically. The second drive mechanism 32 is drively connected to the second baffle 4 to drive the second baffle 4 back and forth between the second blocked position and the second open position. The second drive mechanism 32 is a prior art cam-linkage mechanism.

[0016] In practical use, after the elevator levels off, the first drive mechanism 31 and the second drive mechanism 32 activate to move the first baffle 3 to the first blocking position and the second baffle 4 to the second blocking position, then the elevator car door opens. After the elevator car door closes, the first drive mechanism 31 and the second drive mechanism 32 activate to move the first baffle 3 to the first open position and the second baffle 4 to the second open position, then the elevator starts running. In the above method, when the first baffle 3 is in the first blocking position, it can block part or all of the horizontal gap, thereby reducing the horizontal gap. When the second baffle 4 is in the second blocking position, it can block part or all of the lateral gap, thereby reducing the lateral gap. The combination of the above methods can reduce the horizontal and lateral gaps between the car door sill 1 and the landing door sill 2, effectively preventing small items from falling, meeting the safety requirements of elevator use, and demonstrating strong practicality.

Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
