Problems solved by technology

In addition, this structure is difficult to apply between two door panels, because in this case it directly reduces the size of the door opening and its edges or flanges may catch elevator passengers or objects they carry.

Embodiment Construction

[0031] This finger guard sensor has 4 parts, including an infrared sensor, which includes a pair of transmitter 1 and receiver 3 . The infrared sensor is accommodated in the rubber tube 2 . A rubber tube 2 of a specific length is inserted into an aluminum open tube 4 for maintaining straightness and for fixing the whole assembly in the door frame.

[0032] The sensor works as an electronic non-contact switch. At one end, an infrared transmitter inside the rubber tube continuously emits an infrared-coded signal, and a receiver at the other end receives the signal and measures the time difference between signal transmissions to check the continuity of the connection.

[0033] The rubber tube serves as the channel for the transmission, and if the channel is blocked or obstructed to a certain degree by foreign objects, the transmission will not be successful. If the receiver cannot receive a complete segment within a specified period of time, the transmission is considered incom...

Abstract

The invention relates to a safety device in a door, which device comprises at least one door leaf, a door frame and a gap between the door leaf and the door frame or a gap between door leaves. An elastic device is located close by the gap.

Description

technical field [0001] The invention relates to a safety device for an elevator door, which comprises at least one door leaf, a door frame and a gap between the door leaf and the door frame or a gap between the door leaves. Background technique [0002] Especially with smaller children, who may be inattentive and have small fingers, there is a risk of accidentally inserting their fingers into a gap in the elevator door, i.e. between two door panels sliding against each other or between the door panel and the door frame in the gap between. The width of such gaps or gaps is typically 5-6 mm, and smaller gaps are difficult to achieve because of the tolerances required during manufacture and operation. [0003] Often children show excitement about moving objects and when waiting for an elevator to arrive, they tend to place their little hands on the glass door panels of elevators that are commonly installed in shopping malls. When the elevator car reaches the floor, the elevat...
