Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator footboard device. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building; the car runs in a shaft that connects all floors. When the elevator reaches the lobby of the target floor, the bottom of the elevator car may be higher than the bottom of the lobby due to positioning errors caused by a malfunction. At this time, the elevator door opens according to the established procedure. If the passengers do not leave a gap between the height difference between the bottom of the car and the lobby and put their feet into the gap, the abnormal operation of the elevator may cause injuries to the feet caused by the car and the lobby floor.

[0003] In order to avoid the above-mentioned injury accidents, it is very necessary to install a car toe guard as a safety protection device on the side of the car door at the bottom of the car. The national standard stipulates that a toe guard device should be installed under the car door sill. The height of the vertical part should not be less than 750mm. The vertical part should extend downward with an inclined surface. The angle between the inclined surface and the horizontal plane should not be less than 60°. The projection of the inclined surface on the horizontal plane should not be less than 20mm. It should be able to withstand any position of the lower edge of the vertical part of the toe guard from the floor station to the toe guard, and evenly distributed within 5cm. 2 The static force of 300N on the circular (or square) area should meet the requirements of permanent deformation no more than 1mm and elastic deformation no more than 35mm. Therefore, it is necessary to reinforce the car footboard to improve the overall structural strength of the footboard. Utility Model Content
