Receiver (lock)

from Wikipedia, the free encyclopedia

The action frame (also: Baskül, Baskule, bascule, Basquille) (. Bascule French: flip-flop, rocker ) in the closed technique in designated window - and doors as well as in Cabinets the central gear a push rod closure , which is also Baskülenverschluss or espagnolette lock is called. A modern designation for the basket gear is blow bar gear .

The push rods are moved simultaneously and in opposite directions with a rotary handle, the olive , via a simple rack or coupling gear (usually up and down for doors and windows).

The receiver lock is also used to secure safe doors . Here, a number of the push rods distributed over the entire door are often connected to a central, rotatable disc so that they can all be operated from the outside at the same time by a lever or a handwheel.

Just like the espagnolette clasp , the receiver was developed in the late Baroque era and was only replaced by more modern locking systems in the 20th century. In historicism , connecting rods and gears were usually embedded in the internal cuff strips and covered by them.

In a similarly functioning lever lock , only one push rod is moved vertically. As with the basque lock, its lower end slides into a bracket attached to the frame, while the upper end is provided with an eyelet that latches into a hook. The handle stands straight up and is pulled forward to open the sash.
