(54) | Improvements relating to closure members |
(57) A drive transfer and locking mechanism for a closure member (15), said mechanism
comprising a first arm (12) to be moved arcuately by drive means (11) for effecting
pivotal opening and closing of an aperture by the closure member (15), and a second
arm (14) to support the closure member (15). Detent means (20) are provided to interengage
and interconnect the first and second arms (12,14), the detent means (20) being resiliently
operable in a generally vertical direction under the inherent resiliency of at least
the first arm (12). The mechanism additionally includes magnetic means (25) to provide
a magnetic attractive force between magnetically permeable regions of the two arms
(12,14) to aid the detent means (20) in holding said interengaged and interconnected
condition of the first and second arms (12,14). |
