DEFINITION

Classification: 359/544

Including a snap, spring clip, or spring retainer:

(under subclass 543) Subject matter wherein either the curved refracting surface or the reflecting surface behind the refractor are individually mounted on a support by being pushed into a retainer which opens for entrance and closes around a portion of the element when it is in the settled position or a coil spring holds each element in place.

(1) Note. The snap or spring clip retainer could either clamp onto the refractor/reflector or could be used to clamp a retainer to a housing and the refractor/reflector force fitted into the retainer. The combination of a refractor/reflector and a retainer that is snapped into a third device belong in this subclass.

(2) Note. A rubber slot into which the refractor or reflector are pushed into for retention in the slot belong in subclass 543.

(3) Note. Although the reflector buttons of this subclass are often referred to as lenses, these have not been crossed into lenses since these simply reflect the light falling on them rather than create a single image of an object at a focal point. These buttons are often referred to as auto collimating.
