US12510745 - Toolless knob assembly for optical device

Various embodiments described herein may include a rotatable assembly including a rotatable knob, the rotatable assembly further including: a collet or other body having capturing member(s) to at least partially surround or flank a spindle; and a grippable device usable to move the collet relative to the spindle to disengage the capturing member(s) from the spindle; wherein the knob and the spindle rotate together as a unit when the capturing member(s) are engaged to the spindle, and wherein the knob rotates relative to the spindle when the capturing member(s) are disengaged from the spindle. Other embodiments may be disclosed and/or claimed.

The patent describes a toolless knob assembly for an optical device that allows for the rotation of a knob relative to a spindle through a collet mechanism. This design enables the knob and spindle to rotate together when engaged, while allowing for independent rotation when disengaged.

Claim 1

1 . An apparatus, comprising: a rotatable assembly including a rotatable knob or another first rotatable part, the rotatable assembly further including: a collet or another body having one or more capturing members to at least partially surround or flank a spindle or another second rotatable part; and a retaining cap or another grippable part usable to move the collet or the other body relative to the spindle or the other second rotatable part to disengage the one or more capturing members from the spindle or the other second rotatable part; the rotatable assembly configured to bias the collet or the other body in a direction away from the spindle or the other second rotatable part; wherein the knob or the other first rotatable part and the spindle or the other second rotatable part rotate together as a unit when the one or more capturing members are engaged to the spindle or the other second rotatable part, and wherein the knob or the other first rotatable part rotates relative to the spindle or the other second rotatable part when the one or more capturing members are disengaged from the spindle or the other second rotatable part. a rotatable assembly including a rotatable knob or another first rotatable part, the rotatable assembly further including: a collet or another body having one or more capturing members to at least partially surround or flank a spindle or another second rotatable part; and a collet or another body having one or more capturing members to at least partially surround or flank a spindle or another second rotatable part; and a retaining cap or another grippable part usable to move the collet or the other body relative to the spindle or the other second rotatable part to disengage the one or more capturing members from the spindle or the other second rotatable part; the rotatable assembly configured to bias the collet or the other body in a direction away from the spindle or the other second rotatable part; wherein the knob or the other first rotatable part and the spindle or the other second rotatable part rotate together as a unit when the one or more capturing members are engaged to the spindle or the other second rotatable part, and wherein the knob or the other first rotatable part rotates relative to the spindle or the other second rotatable part when the one or more capturing members are disengaged from the spindle or the other second rotatable part.
