Description

Technical Field

[0001] The utility model relates to the technical field of elevator doors, in particular to a sill assembly for elevator doors. Background Art

[0002] The sill of the elevator door, also known as the floor threshold or footing, is a structure at the lower edge of the elevator door, usually made of metal material, which plays a supporting and guiding role. The sill assembly can protect the bottom of the elevator door from impact by hard objects and reduce damage caused by impact. The design and material of the sill will also take into account the consistency with the overall decoration style of the elevator, and has a certain decorative effect.

[0003] As an important part of modern buildings, the safety and comfort of elevators are of vital importance to users. As an important part of the elevator door system, the elevator door sill is used to ensure the seal between the elevator door and the hall door, and to prevent gas leakage in the elevator shaft and dust from entering the car. However, the existing elevator door sills have poor sealing performance and cannot effectively prevent dust, moisture and other debris from entering the elevator. Therefore, we propose a sill assembly for elevator doors to solve the above problems. Utility Model Content
