Abstract
Disclosed herein are latch assemblies configured to releasably attach to a locking pin. The latch assemblies disclosed herein may, for example, be used to secure an adjustable window either in a deployed position or an undeployed position. Generally, the latch assemblies disclosed herein include a primary locking plate configured to secure the locking pin in the latch assembly. The latch assemblies disclosed herein also include a secondary locking plate configured to guide the locking pin into the primary locking plate. The latch assemblies disclosed herein also include a release lever allowing a user to simultaneously disengage both the primary and the secondary locking pin to detach the latch assembly from the locking pin.
Claims20
A latch assembly for securing a window frame to a fixed housing comprising:
- a mounting plate configured to fixedly secure the latch assembly to the window frame;
- a primary locking plate mounted to the mounting plate, including a notch for receiving a locking pin, wherein the primary locking plate is rotatable around a first hinge pin, and movable between an open position and a closed position by rotating about the first hinge pin;
- a secondary locking plate mounted to the mounting plate, rotatable around a second hinge pin, and movable between an undeflected position and a deflected position;
- a release lever connected to the mounting plate and rotatable around a third hinge pin from an unlocked position to a locked position to prevent rotational movement of the primary locking plate;
- wherein the secondary locking plate is configured to engage a locking pin mounted on the fixed housing,
- wherein the primary locking plate is configured to rotate from the open position to the closed position when the locking pin is received in the notch, and
- wherein the primary locking plate is configured to secure the locking pin against the mounting plate, when the primary locking plate is in the closed position.
A work vehicle comprising:
- an operator cab having a fixed housing and a locking pin mounted to the fixed housing;
- a window;
- and
- a latch assembly mounted to the window and configured to releasably secure the window to the housing of the operator cab, the latch assembly comprising:
- a mounting plate having configured to fixedly secure the latch assembly to the window;
- a cover plate vertically spaced apart from the mounting plate and partially defining an enclosure between the cover plate and the mounting plate;
- a first locking plate mounted to the mounting plate and rotatable around a first hinge pin between an open position and a closed position and including a notch configured to receive the locking pin;
- a second locking plate mounted to the mounting plate and rotatable around a second hinge pin between a deflected position and an undeflected position;
- and
- a release lever mounted to the mounting plate and rotatable around a third hinge pin between a locked position and an unlocked position;
- wherein when the notch of the first locking plate receives the locking pin, the first locking plate is urged by the locking pin from the open position to the closed position and the release lever engages the first locking plate to prevent the first locking plate from returning to the open position, and
- wherein when the locking pin is contained within the enclosure, and the second locking plate is in the undeflected position, the second locking plate prevents the locking pin from exiting the enclosure.
