Abstract
A locking rotary latch assembly has a shank bearing about the shank on the exterior side of a latch housing, and an interior load bearing bushing about the shank on the interior side of the latch housing which also intersects and guides a sliding locking arm. A latching arm is mounted on the end of the shank against the load bearing bushing which includes a portion that is in contact with the housing adjacent the exterior shank bearing so that forces applied to the shank are resisted by the combination of the load bearing bushing, and the exterior shank bearing against the portion of the load bearing bushing in contact with the housing. The exterior shank bearing prevents passage of the shank from the exterior to the interior side of the housing.
Claims15
A latch assembly comprising, in combination,
- a latch housing having an exterior side and an interior side,
- a rotatable shank intersecting the housing,
- a handle attached to the shank on the exterior side of the housing,
- a latch attached to the shank on the interior side of the housing,
- a load bearing bushing about the shank between the latch and the interior side of the housing,
- a locking slide on the interior side of the housing having an opening through which the shank passes, the locking slide opening adapted to receive a first portion of the bushing, to slide adjacent the first portion of the bushing, and to slide between a second portion of the bushing and the interior side of the housing.
A latch comprising,
- a latch housing adapted to be mounted and having an exterior side and an interior side,
- a rotatable shank which intersects the latch housing,
- a latching arm attached to an end of the shank on the interior side of the latch housing,
- a load bearing bushing about the shank between the latching arm and the interior side of the housing, the load bearing bushing having a generally cylindrical section with a substantially flat top surface disposed generally flush against a surface of the latching arm, and slide guides which extend axially from the cylindrical section of the load bearing bushing for contact with the interior side of the housing, and
- the shank further having an integrally formed flange which extends from the shank on the exterior side of the housing, a shank bearing about the shank between the shank flange and the exterior side of the housing, the shank flange overlapping a portion of the shank bearing, whereby contact of the shank flange with the shank bearing prevents passage of the shank from the exterior side of the housing to the interior side of the housing, and
- a handle attached to an end of the shank on the exterior side of the latch housing.
A latch assembly comprising,
- a latch housing having an interior side and exterior side;
- a latch shank intersecting the housing;
- a latching arm attached to the latch shank on the interior side of the housing;
- a load bearing bushing about the shank between the latching arm and the interior side of the housing, the load bearing bushing having a generally cylindrical section with a substantially flat top surface disposed generally flush against a surface of the latching arm, and slide guides which extend axially from the cylindrical section of the load bearing bushing for contact with the interior side of the housing;
- a shank bearing disposed about the shank between the exterior side of the housing and a flange which extends from the shank;
- and
- a handle attached to the shank on the exterior side of the housing.
