Embodiment 1

[0022] see Figure 2a and Figure 2b , which is Embodiment 1 of the safety device at the bottom of the elevator car of the present application, which includes:

[0023] - The toe guard 11 is a whole piece of metal plate, which is rotatably fixed on the bottom of the elevator car 10 near the car door (ie the bottom of the sill) by the first hinge 91 . The toe guard 11 can rotate away from the direction of the elevator landing 40 . When the toe guard 11 is deployed, the whole body is vertical, its main body is vertically downward, and only the end is inclined away from the direction of the elevator landing 40 . When the toe guard 11 is folded, the whole is nearly horizontal, depending on the connection line between the first hinge 91 and the fixed position of the toe guard hook 8 .

[0024] ——The buffer bumper 12 is a rigid component, and is rotatably fixed on the bottom of the elevator car 10 through the second hinge 92 , usually fixed on the bottom center of the elevator ca...

Embodiment 2

[0035] see Figure 3a and Figure 3b , which is the second embodiment of the safety device at the bottom of the elevator car of the present application, which includes:

[0036] - The toe guard 11 is a whole piece of metal plate, which is rotatably fixed on the bottom of the elevator car 10 near the car door (ie the bottom of the sill) by the first hinge 91 . The toe guard 11 can rotate away from the direction of the elevator landing 40 . When the toe guard 11 is deployed, the whole body is vertical, its main body is vertically downward, and only the end is inclined away from the direction of the elevator landing 40 . When the toe guard 11 is folded, the whole is nearly horizontal, depending on the connection line between the first hinge 91 and the fixed position of the toe guard hook 8 .

[0037] ——The buffer bumper 12 is a rigid component, and is rotatably fixed on the bottom of the elevator car 10 through the second hinge 92 , usually fixed on the bottom center of the el...

Abstract

The present application discloses a safety device for the bottom of an elevator car, comprising: - a toe guard, rotatably fixed on the bottom of the elevator car through a first hinge; it has an unfolded state and a folded state. - The bumper bumper is rotatably fixed at the bottom of the elevator car through the second hinge; the bumper bumper has an unfolded state and a folded state. ——The linkage mechanism is a rigid component, one end is connected to the toe guard through the third hinge, and the other end is connected to the buffer bumper or the bottom of the elevator car through the fourth hinge; the linkage mechanism makes the toe guard and the bumper bumper in the unfolded state or folded state. ——The toe guard hook is fixed at the bottom of the elevator car near the car door; when the toe guard is in a folded state, the toe guard hook hooks the toe guard to keep the folded state unchanged. The present application provides a toe guard and a bumper bumper that can be unfolded and folded synchronously, which can be applied in the environment of shallow pits.

Description

technical field [0001] The application relates to a safety device at the bottom of an elevator car, in particular to a toe guard and a bumper bumper. Background technique [0002] see figure 1 , the elevator car 10 moves up and down in the elevator shaft 30 along the car guide rail 20, and stops at each elevator landing 40 as required. At the bottom of the elevator car 10 there is a vertically downwardly extending toe guard 11 close to the side of the car door, which is a thin metal plate with a slope towards the elevator shaft 30 direction at the end, and the total height is not less than 750mm. When the elevator car 10 stays at a non-floor location (such as above a certain floor) due to a fault and needs to rescue passengers from the elevator car 10, the elevator toe guard 11 is used to prevent passengers from falling into the elevator shaft 30. At the center of the bottom of the elevator car 10, there is also a buffer bumper 12, which is a downwardly extending rigid com...
