Locking adjustment turret
First Claim
1. A locking adjustment turret comprising:
- a rotating adjustment portion mounted in a stationary portion and carrying a locking mechanism, the rotating adjustment portion including an engagement portion that is moved axially when the rotating adjustment portion is rotated, the locking mechanism substantially preventing rotation of the rotating adjustment body when engaged;
wherein the locking mechanism includes a detent pin projecting from a detent body carried in the rotating adjustment portion, a lock body on which a lock knob is mounted and from which a lock pin projects toward the detent body, the lock body being carried in the rotating adjustment portion such that rotation of the lock knob moves the lock pin axially toward and away from the detent body, rotation of the lock knob in one direction moving the lock pin into engagement with the detent body and preventing motion of the detent body, thereby retaining the rotating adjustment portion in a position;
wherein the rotating adjustment portion includes a shaft and a main body, the main body carrying the locking mechanism and the shaft carrying the engagement portion;
wherein the main body includes an axial bore in an upper portion thereof and in which the lock body is mounted and retained; and
wherein the lock body includes a lock knob mount projecting from a main lock body portion, the main lock body portion also supporting the lock pin and having a diameter larger than the lock knob mount, the locking mechanism further comprising a lock body retaining device mounted in the upper portion of the rotating adjustment portion main body so that the main lock body is prevented from exiting the bore in which it is mounted.

Abstract
A locking adjustment turret for rifle scopes includes a stationary portion mounted on an outer tube of the scope, a rotating adjustment portion supported in the stationary portion and including an adjustment knob such that rotation of the knob results in axial motion of a shaft toward and away from an inner tube of the scope, and a locking mechanism on the rotating adjustment portion that locks the shaft in a desired position. The locking mechanism includes a pin that engages a detent mechanism in the rotating adjustment portion, preventing rotation of the rotating adjustment portion. The locking mechanism is operated with a lock knob that sits atop the adjustment knob and is accommodated by a recess in the top of the adjustment knob.

5. A locking adjustment turret comprising a stationary portion, a rotating adjustment portion, and a locking mechanism in which the stationary portion includes:
-
an outer barrel; and an inner body; and
the rotating adjustment portion includes;a main body; a shaft projecting from a lower end of the main body, an engagement end of the shaft being arranged to engage an object to be adjusted; an upper portion of the main body; an adjustment knob mounted on the upper portion of the main body for rotation therewith; a detent mechanism in the main body configured to interact with the inner body of the stationary portion; and the main body being retained in the stationary portion such that when the adjustment knob is turned, the main body moves axially relative to the stationary portion to move the engagement end of the shaft away from and toward the stationary portion depending on a direction in which the adjustment knob is turned; and the locking mechanism includes; a lock knob; a lock body; a lock knob mount on an upper end of the lock body; a main lock body portion from which the lock knob mount projects and of larger diameter than the lock knob mount; a lock pin projecting from a lower end of the main lock body toward the detent mechanism; and the lock body being retained in the upper portion of the rotating adjustment portion such that when the lock knob is turned, the lock body and lock pin move axially relative to the rotating adjustment portion moving the lock pin toward and away from engaging the detent mechanism depending on the direction in which the lock knob is turned. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A locking adjustment turret comprising a stationary portion, a rotating adjustment portion, and a locking mechanism in which the stationary portion includes:
-
an outer barrel comprising a plurality of equally spaced longitudinal grooves on an inner surface of an upper portion of the outer barrel; and an inner body comprising a central axial bore extending therethrough and including threads; and the rotating adjustment portion includes; a main body including a partially diametral bore; a shaft projecting from a lower end of the main body and carrying threads that engage and cooperate with the threads of the inner body central axial bore, an engagement end of the shaft being arranged to engage an object to be adjusted; an upper portion of the main body including a longitudinal bore with an opening at a top of the main body upper portion and intersecting the partially diametral bore, the main body longitudinal bore including an inner surface carrying threads; an adjustment knob mounted on the upper portion of the main body for rotation therewith; a detent mechanism in the main body partially diametral bore and configured to interact with the inner body of the stationary portion, the detent mechanism including a detent pin projecting from a detent body mounted in the partially diametral bore, the detent pin extending toward and engaging the longitudinal grooves of the outer body inner surface, the detent mechanism further including a biasing device that urges the detent pin toward engagement with the longitudinal grooves; and the main body being retained in the stationary portion by the cooperation of the threads on the main body and the threads in the axial bore such that when the adjustment knob is turned, the main body moves axially relative to the stationary portion to move the engagement end of the shaft away from and toward the stationary portion depending on a direction in which the adjustment knob is turned; and the locking mechanism includes; a lock knob; a lock body; a lock knob mount on an upper end of the lock body; a main lock body portion from which the lock knob mount projects and of larger diameter than the lock knob mount, the main lock body portion including threads on an outer surface thereof that cooperate with the threads of the main body upper portion longitudinal bore; a lock pin projecting from a lower end of the main lock body toward detent body; and the lock body being retained in the upper portion of the rotating adjustment portion by cooperation of the threads on the main lock body portion and the upper portion longitudinal bore such that when the lock knob is turned, the lock body and lock pin move axially relative to the rotating adjustment portion moving the lock pin toward and away from engaging the detent mechanism depending on the direction in which the lock knob is turned, the locking adjustment turret further comprising a lock position in which the lock pin engages and restrains the detent body from axial motion.
