Filed:

Apr 13, 2021

Appl. No.:

17/228963

Inventors:

- Oklahoma City OK, US
Robin D. Davidson - Wheatland OK, US

International Classification:

G07C 9/00

Abstract:

A lock comprising a housing, a plunger, a locking member, a locking plate, and a control assembly. The housing having an internal cavity, a recess, and a bore. The plunger is disposed in the bore and is slidable between a closed position wherein a second end of the plunger is positioned in the internal cavity and an intermediate portion of the plunger extends across the recess, and an open position wherein the plunger is withdrawn from the internal cavity and the recess. The locking member is movable between a locking position wherein the locking member is engaged with the plunger and an unlocking position wherein the locking member is disengaged therefrom. The control assembly operates the locking plate between a lock position to hold the locking member in the locking position and an unlock position to permit the plunger to move from the closed position to the open position.

International Classification:

F16D 3/30

Abstract:

A rotary joint constant velocity stabilizer for connecting a first rotatable body and a second rotatable body, the first and second rotatable bodies being rotatable about a generally common axis of rotation and rotatable at substantially similar angular velocities. The rotary joint constant velocity stabilizer has a first base, a second base, and a shaft. The shaft is connected to first base such that the shaft is pivotable relative to the first base about a first axis extending from a first side to a second side of the first base. The shaft is connected to the second base such that the shaft is pivotable about a second axis extending from a first side to a second side of the second base, the shaft being slidable relative to the second base along a third axis normal to the first axis and the second axis, and rotatable relative to the second base about the third axis while preventing relative rotational motion between the first base and the second base.
