Door opening control device

摘要

#CMT# #/CMT# The device has a rotatable attaching unit including a pin (28) interdependent in rotation of an element consisted by a lath (16) and a handle (10) that is adapted to be actuated by a user. A receiving part (40) is interdependent in rotation of another element and presenting a receiving cavity (40A). An activation unit i.e. electromagnet (56) is adapted to cause displacement of the pin in parallel with rotation axis (A) between a deactivated position. The pin is moved apart from the receiving cavity and an activated position in which the pin is engaged in the receiving cavity. #CMT#USE : #/CMT# Control device for opening a door. #CMT#ADVANTAGE : #/CMT# The arrangement of the attaching unit allows solidarisation of the device in a reliable manner, and simple insertion of the pin in the receiving cavity while the pin can be dimensioned by having low dimensions, and resisting shearing forces allowing the solidarisation in rotation, and avoiding the need to have high amplitude axial displacement. The pin can be placed in a part of an axial projecting handle on the door without requiring large radial dimensions for the handle and requiring a base plate or a fixing rosette for the handle to the door of larger size. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a vertical cross-sectional view of a control device.
