Abstract
A rotary latch assembly is provided which can be configured as right-handed and left-handed using the same rotor and catch components, without reconfiguring the front and back plates. The axles for the rotor and catch are identical so that the rotor and catch can be interchanged on the axles. The latch biasing springs are mirror images so as to be used on either the rotor or the catch. The latch includes multiple connection points for single or dual actuators, and a lifting block to align the assembly with a striker.
Claims32
A rotary latch assembly comprising:
- a front plate;
- a back plate connected to the front plate;
- a pair of axles mounted between the front and back plates;
- a rotor rotatively mounted on one of the axles for movement between latched and unlatched functional positions;
- a catch rotatively mounted on the other one of the axles for movement between latched and unlatched functional positions;
- the rotor and catch each having opposite first and second faces, and each being mountable in a first mounting position on the axles with the first faces directed outwardly to form a right-handed latch and in a second mounting position on the opposite axles with the second faces directed outwardly to form a left-handed latch;
- and
- the front and back plates being oriented the same in both the right-handed and left-handed latches.
A rotary latch assembly, comprising:
- front and back plates connected together;
- a pair of axles extending between the front and back plates;
- a rotor and a catch interchangeably mounted on the axles;
- the plates each being symmetrical about a center lines so as to form left and right-handed latches when the rotor and catch are exchanged on the axles;
- and multiple attachment points on the plates for mounting an actuator or trip lever.
A rotary latch assembly, comprising:
- front and back plates connected together;
- a pair of axles extending between the front and back plates;
- a rotor and a catch interchangeably mounted on the axles;
- the plates each being symmetrical about a center line so as to form left and right-handed latches when the rotor and catch are exchanged on the axles;
- dual actuators or trip levers mounted on the assembly to actuate the catch;
- and
- wherein one of dual actuators or trip levers is mounted on the front plate and the other of the dual actuators or trip levers is mounted on the back plate.
A rotary latch assembly, comprising:
- front and back plates connected together;
- a pair of axles extending between the front and back plates;
- a rotor and a catch interchangeably mounted on the axles;
- the plates each being symmetrical about a center line so as to form left and right-handed latches when the rotor and catch are exchanged on the axles;
- dual actuators or trip levers mounted on the assembly to actuate the catch;
- and
- wherein the dual actuators or trip levers are both mounted on the front plate.
A rotary latch assembly, comprising:
- front and back plates connected together;
- a pair of axles extending between the front and back plates;
- a rotor and a catch interchangeably mounted on the axles;
- the plates each being symmetrical about a center line so as to form left and right-handed latches when the rotor and catch are exchanged on the axles;
- and
- a tab on the back plate to limit rotational movement of the trip levers.
