Abstract
A pre-assembled front-loading lock having a first cam fixedly mounted on its shaft, a second cam parallel to the first cam and rotatably mounted on the shaft, and a locking member fixedly mounted on the shaft to secure the second cam against rotation with respect to the first cam when the second cam has been rotated about the shaft a predetermined amount. As a result, the lock with the cams can be pressed through a panel opening and the cams thereafter be readily moved into operating position. A stop is provided on the locking member to prevent the second cam from being rotated in the wrong direction.
Claims14
A pre-assembled lock adapted for front-mounting through an opening in a panel, said lock including
- a face plate, a barrel extending transversely therefrom, and a shaft extending from said barrel,
- a first cam fixedly mounted on said shaft,
- a second cam pivotally mounted on said shaft, said second cam being substantially parallel to said first cam,
- and locking means for locking said second cam against pivoting relative to said first cam after said second cam has been pivoted a predetermined distance about said shaft to its operating position.
- whereby said lock with said cams can be pressed through a panel opening and said cams thereafter be readily placed in operating positions fixed relative to each other.
In a dual-cam lock made for front installation through an opening in a panel, the lock including a face plate, a barrel extending from the face plate, and a shaft extending from the barrel, that improvement including
- a first cam fixedly mounted on said shaft for rotation therewith,
- a second cam mounted on said shaft and rotatable therewith, said second cam being substantially parallel to said first cam, and
- locking means which lock said second cam against further rotation relative to said shaft and said first cam, after said second cam has been rotated a predetermined angle from said first cam to its operating position,
- whereby said lock can be passed through said opening in a panel and said second cam thereafter moved to, and locked into, operating position.
A pre-assembled lock adapted for front-mounting through an opening in a panel, said lock including
- a face plate, a barrel extending transversely therefrom, and a shaft extending from said barrel,
- a first cam fixedly mounted on said shaft,
- a second cam rotatably mounted on said shaft, said second cam being substantially parallel to said first cam,
- and locking member for locking said second cam against rotation relative to said first cam after said second cam has been rotated a predetermined amount about said shaft, said locking member being non-rotatably mounted on said shaft and abutting said second cam,
- interengagement means operable between said locking member and said second cam, said interengagement means including a projecting spring on said locking member and a complementary spring-engaging slot on said second cam,
- whereby said lock with said cams can be pressed through a panel opening and said cams thereafter be readily placed in operating positions.

- a first cam fixedly mounted on said shaft,
- a second cam pivotally mounted on said shaft, said second cam being substantially parallel to said first cam,
- locking means for locking said second cam against pivoting relative to said first cam after said second cam has been pivoted a predetermined distance about said shaft, said locking means being a locking member non-rotatably mounted on said shaft and abutting said second cam
- interengagement means operable between said locking member and said second cam, said interengagement means including a projecting spring on said locking member and a complementary spring-engaging slot on said second cam,
- whereby said lock with said cams can be pressed through a panel opening and said cams thereafter be readily placed in operating positions.

- a face plate, a barrel extending transversely therefrom, and a shaft extending from said barrel,
- a first cam fixedly mounted on said shaft,
- a second cam pivotally mounted on said shaft, said second cam being substantially parallel to said first cam,
- locking means for locking said second cam against pivoting relative to said first cam after said second cam has been pivoted a predetermined distance about said shaft, said locking means being a locking member non-rotatably mounted on said shaft and abutting said second cam, and
- a stop on said locking member positioned to prevent inadvertent pivoting of said second cam in an undesired direction.
- whereby said lock with said cams can be pressed through a panel opening and said cams thereafter be readily placed in operating positions.
In a dual-cam lock made for front installation through an opening in a panel, the lock including a face plate, a barrel extending from the face plate, and a shaft extending from the barrel, that improvement including
- a first cam fixedly mounted on said shaft for rotation therewith,
- a second cam mounted on said shaft and rotatable therewith, said second cam being substantially parallel to said first cam, and
- locking means which lock said second cam against further rotation relative to said shaft after said second cam has been rotated about said shaft to a predetermined angle from said first cam,
- said locking means being a locking member non-rotatably mounted on said shaft and abutting said second cam, and interengagement means operable between said locking member and said second cam, said interengagement means including a projecting spring on said locking member and a complementary spring-engaging slot on said second cam,
- whereby said lock can be passed through said opening in a panel and said second cam thereafter moved to operating position.
In a dual-cam lock made for front installation through an opening in a panel, the lock including a face plate, a barrel extending from the face plate, and a shaft extending from the barrel, that improvement including
- a first cam fixedly mounted on said shaft for rotation therewith,
- a second cam mounted on said shaft and rotatable therewith, said second cam being substantially parallel to said first cam, and
- locking means which lock and second cam against further rotation relative to said shaft after said second cam has been rotated about said shaft to a predetermined angle from said first cam,
- said locking means being a locking member non-rotatably mounted on said shaft and abutting said second cam, and a stop on said locking member positioned to prevent inadvertent rotation of said second cam in an undesired direction,
- whereby said lock can be passed through said opening in a panel and said second cam thereafter moved to operating position.
