A dial shift lever device for a vehicle may be provided that includes: a dial knob which is rotatable from a predetermined reference position by a user's operation for changing a shift stage; a button driving part which comprises a plurality of buttons disposed circumferentially in a receiving recess formed in a lower portion of the dial knob and generates a signal for selecting the shift stage as at least one of the plurality of buttons is pressed by rotation of the dial knob; and a guide assembly which is coupled to the lower portion of the dial knob and locks the rotation of the dial knob or releases the lock of the rotation of the dial knob.

An airbrake locking assembly for keeping parking brake engaged on a vehicle with airbrakes includes a vehicle that has airbrakes which include a parking brake plunger. The parking brake plunger is positionable in an actuated position and an un-actuated position. A collar is provided that has a first half being pivotally coupled to a second half. The collar is positionable around the parking brake plunger when the parking brake plunger is positioned in the actuated position. Moreover, the collar inhibits the parking brake plunger from being urged into the un-actuated position when the collar is positioned around the parking brake plunger. In this way the vehicle is retained in a parked position thereby enhancing safety for individuals entering and exiting the vehicle. A lock is coupled to first half of the collar and releasably engages the second half.

Embodiments of the present technology relate to safety knobs. An example automatic locking knob assembly includes a knob, a base, an adapter, and a locking sub-assembly. The locking sub-assembly is configured to automatically lock the knob into place when a valve stem of a stove is in an off position. The locking sub-assembly also allows for controlled rotation of the valve stem of the stove by actuation of buttons associated with the knob.

An apparatus for preventing mal-operation for an automatic transmission, which is formed as one body including a plurality of parts, is provided, whereby it is possible to simplify the structure and the manufacturing process thereof.

A control knob for controlling the operation of a component of a household appliance is disclosed. The control knob includes a body configured to be attached to a rotatable rod extending from the appliance. A locking element reversibly secures the body in at least one rotational position. The locking element is movable between a first position and a second position. The locking element is configured to engage with a notch to rotatably secure the body in the at least one rotational position when the locking element is in the first position, and to disengage from the notch to permit the body to be rotated when the locking element is in the second position.

A cruise control system for work machines. The system comprises one or more levers for controlling the velocity of the work machine and one or more magnet assemblies. The magnet assemblies comprise means of overcoming the neutral bias of a control lever so that the velocity of the work machine may be maintained without manual input from the operator. The magnets may act directly upon a control lever or a surface adjacent a control lever. Additional controls may be employed to set a maximum cruising speed for the work machine when cruise control is engaged.

A locking mechanism for releasably locking a lock bolt against axial movement includes a solenoid assembly arranged, in use, in proximity to an axially moveable lock bolt. The solenoid assembly includes: a solenoid, a solenoid bias spring and a solenoid plunger having a plunger tip. When the solenoid is energised, the bias spring causes the solenoid plunger to move to bring the plunger tip into locking engagement with the lock bolt to prevent axial movement thereof, and when the solenoid is not energised, the solenoid bias spring causes the solenoid plunger to move to bring the plunger tip out of locking engagement with the lock bolt thus permitting axial movement thereof.

A control system is for a high lift assembly of an aircraft. The assembly is controllable in two aerodynamic configurations each with different lift. The control system includes a manual control device operable by a pilot of the aircraft. The manual control device includes at least one member movable relative to a base body. The movable member can be moved relative to the base body between a rest position, a first position and a second distinct position. The manual control device includes a resilient return device for the movable member in the rest position. The manual control device issues a signal when the movable member reaches either the first or second position, to move the high lift assembly between two of the aerodynamic configurations.

A rotary operator includes a rotary member, an operation knob capped on the rotary member in a first direction, and a locking member including a first portion fitted in a side of the operation knob opposite from the rotary member in the first direction and a second portion extending in a second direction orthogonal to the first direction to be engaged with the rotary member.
