Abstract
A lever latching system comprising: a housing; a lever having a latch pin fixedly mounted to the lever, the lever being movably mounted to the housing so that the latch pin moves in an arc; and a latch plate movably mounted to the housing for linear movement with respect to the housing, the latch plate comprising a labyrinth for receiving the latch pin.
Claims21
(canceled)
A method for operating a mechanism having a first state and a second state, the method comprising:
- providing or obtaining a lever latching system comprising:
- a housing connected to the mechanism to be operated;
- a lever connected to the mechanism to be operated;
- a latch pin fixedly mounted to the lever;
- and
- a latch plate movably mounted to the housing for linear movement with respect to the housing, the latch plate including a labyrinth for receiving the latch pin;
- moving the lever so that the latch pin causes the latch plate to move with respect to the housing and the latch pin is disposed at a latched position within the labyrinth, thereby causing the mechanism to transition from the first state to the second state and maintaining the mechanism in the second state;
- and
- moving the lever so that the latch pin moves out of the latched position within the labyrinth, thereby causing the mechanism to transition from the second state to the first state.
The method of claim wherein the lever is movably mounted to the housing so that the latch pin moves in an arc.
A method for operating a mechanism having a first state and a second state, the method comprising:
- providing or obtaining a latching system comprising:
- a first unit connected to the mechanism to be operated;
- a second unit connected to the mechanism to be operated and including a latch pin, the second unit being movably mounted to the first unit so that the latch pin moves in a prescribed motion;
- a selector plate movably mounted to the first unit;
- and
- a latch plate including a labyrinth for selectively receiving the latch pin, the latch plate being movably mounted to the selector plate;
- moving the second unit so that the latch pin causes the latch plate to move with respect to the first unit so that the latch pin is disposed at a latched position within the labyrinth, thereby causing the mechanism to transition from the first state to the second state and maintaining the mechanism in the second state;
- and
- moving the second unit so that the latch pin moves out of the latched position within the labyrinth, thereby causing the mechanism to transition from the second state to the first state,
A method for operating a mechanism having a first state and a second state, the method comprising:
- providing or obtaining a latching system comprising:
- a first unit connected to the mechanism to be operated;
- a second unit connected to the mechanism to be operated, the first and second units being movably mounted relative to one another;
- a latch pin fixedly mounted to one of the first unit or the second unit;
- and
- a latch plate movably mounted to the other of the first unit or the second unit, the latch plate including a labyrinth for receiving the latch pin;
- moving one of the first unit or the second unit so that the latch pin causes the latch plate to move with respect to the other of the first unit or the second unit so that the latch pin is disposed at a latched position within the labyrinth, thereby causing the mechanism to transition from the first state to the second state and maintaining the mechanism in the second state;
- and
- moving one of the first unit or the second unit so that the latch pin moves out of the latched position within the labyrinth, thereby causing the mechanism to transition from the second state to the first state.
