Abstract
An attachment system for a locking system mounted to a closure is provided. A baseplate is fastenable to a mounting surface of the closure, the baseplate including at least one circumferential cutout having an engagement feature, and a locking feature on a surface of the baseplate. A housing has at least one protrusion insertable into the at least one circumferential cutout and is rotatably engageable with the engagement feature to selectively prevent the housing from being withdrawn from the baseplate in a direction normal to the mounting surface. A locking device is disposed inside the housing and is accessible from outside the housing through a cutout defined in at least one of the housing and the baseplate, the locking device operable to rotatably lock and unlock the housing to the baseplate.
Claims15
An attachment system for a locking system mounted to a closure, the attachment system comprising:
- a baseplate fastenable to a mounting surface of the closure, the baseplate including at least one circumferential cutout having an engagement feature, and a locking feature on a surface of the baseplate;
- a housing having at least one protrusion insertable into the at least one circumferential cutout and rotatably engageable with the engagement feature to selectively prevent the housing from being withdrawn from the baseplate in a direction normal to the mounting surface;
- and
- a locking device disposed inside the housing and accessible from outside the housing through a cutout defined in the housing, the locking device operable to rotatably lock and unlock the housing to the baseplate, wherein the baseplate is non-rotatably fastenable to the mounting surface of the closure via at least one fastener insertable through at least one lug disposed in at least one circumferential track in the baseplate and engaging with at least one lug-locking feature in the at least one circumferential track.
A method for assembling an attachment system for a locking system, comprising:
- providing a locking device inside a housing;
- engaging at least one protrusion projecting from the housing with at least one circumferential cutout of a baseplate to mount the housing to the baseplate;
- rotating the housing relative to the baseplate to rotatably engage the at least one protrusion with an engagement feature in the at least one circumferential cutout to selectively prevent the housing from being withdrawn from the baseplate in a direction normal to a mounting surface;
- selectively rotatably locking the housing to the baseplate via the locking device, the locking device accessible from outside the housing through a cutout defined in the housing and operable to selectively rotatably unlock the housing from the baseplate;
- and
- non-rotatably fastening the baseplate to the mounting surface by inserting at least one lug in at least one circumferential track in the baseplate, engaging the at least one lug with at least one lug-locking feature in the at least one circumferential track and fastening at least one fastener through the at least one lug to the mounting surface.
