RIFLE SCOPE HANDWHEEL KIT

摘要

A kit for fitting a handwheel to a focussing control of a rifle scope is used to enlarge a focussing ring of the control, without having to remove the focussing ring from the control. The handwheel is secured by a headed bolt to a projecting stub shaft. The handwheel has a side plate supporting an outer rim that has a plurality of peripheral indentations to assist turning of the handwheel. The side plate has a central hole and a hub that projects axially from the side plate and defines a bore for receiving the stub shaft. The outer diameter of the hub is received within an outer end portion of the focussing ring. The hub has at least one abutment that co-operates with the stub shaft to inhibit relative rotational movement. A cap bolt extends through the hole to engage the stub shaft and secure the handwheel to the control.

1. A focussing handwheel kit for enlarging a focussing ring of a rifle scope, said kit comprising a handwheel for fitting to a stub shaft of said focussing ring and a cap bolt for securing the handwheel to said stub shaft, in which the handwheel comprises:
an outer rim having an outer periphery for providing said enlarged focussing ring, the outer periphery of the outer rim comprising a plurality of peripheral indentations for assisting manual turning of the handwheel about a rotational axis of the handwheel when the handwheel is fitted to said focussing ring; a side plate, the side plate supporting the outer rim and extending radially inwards from the outer rim towards a central hole in the side plate, the side plate having opposite first and second sides; and a hub, the hub projecting axially away from the second side of the side plate to present a bore within the hub for receiving said stub shaft, said hole extending to said bore and the hub being concentric with said hole about said rotational axis; wherein the cap bolt has a head and a threaded portion, the threaded portion being configured to extend through said hole such that said threaded portion, in use, screws into a threaded bore of said stub shaft received in said hub, and the head being configured to bear on the first side of the side plate opposed to the hub when the threaded portion of the cap bolt is screwed into said threaded bore to secure the handwheel to said stub shaft, and the hub has at least one abutment in the bore within the hub for co-operation with said stub shaft to inhibit relative rotational movement between the handwheel and said stub shaft when the handwheel is secured to said stub shaft by the cap bolt.
