Abstract: A hole opener includes a body with cone arms. The body includes pockets formed in the body in which each of the pockets includes a forwardly-positioned shoulder pocket section, a rearwardly-positioned tapered pocket section and a base opening axially extending through a wall of the corresponding pocket that receives a fastener therethrough. The cone arms each include a cone head attached to an arm. The arm includes a forwardly-positioned shoulder arm section, a rearwardly-positioned tapered arm section, and a rearwardly-facing opening axially extending through the rearwardly-positioned tapered arm section that receives the fastener.

Abstract: A resettable, combination dial lock assembly has a housing, a shackle, and a dial with indicia thereon. A subset of the indicia defines an unlocking combination. The dial is rotatable relative to the housing to positions corresponding to each of the indica subset. A selector is coupled to the dial. Combination members rotate upon rotation of the dial and are each associated with a respective one of the subset of indicia comprising the combination. Rotary members are coupled to the combination members, wherein rotation of the combination members causes rotation of the rotary members. The rotary members and combination members allow entry of the combination by rotating the dial in any direction and independent of a number of rotations made by the dial for activation of the selector to select each of the indicia comprising the combination to unlock the lock assembly.

Abstract: An hydraulically extensible frame is coupled to the hitch portion of a trailer by a pivoting mount. The pivoting mount permits the frame to pivot between a generally vertical operative position and a generally horizontal stowed position. A foot member is secured to an end of the frame opposite the pivoting mount. The foot member engages the ground. An actuator is carried by the frame in a location adapted to be engaged by a foot of a human user when the frame is in the operative or deployed position. The actuator pivots relative to the frame for storage and use as a handle. The actuator selectively extends the frame to raise the hitch portion in response to actuation by the foot of the user.

Abstract: A hitch assembly that includes an anti-rotation mechanism. The hitch assembly generally includes a hitch ball, a ball mount, and a fastener. The invention is directed to a mechanism for preventing rotation of either the hitch ball or the fastener relative to the ball mount. The anti-rotation mechanism of the present invention provides an engagement means for interlocking sections of the hitch ball or fastener with the ball mount, thereby blocking rotation of the hitch ball or fastener relative to the ball mount.

Abstract: In one exemplary embodiment, a combination lock includes a mechanical locking mechanism, a dial, and an electronic interface. The mechanical locking mechanism includes a locking member movable between a locked condition and an unlocked condition. The dial is assembled with the locking mechanism such that successive rotation of the dial to a series of one or more predetermined rotational positions causes the locking mechanism to move the locking member from the locked condition to the unlocked condition. The electronic interface is configured to translate incremental rotational positions of the dial to corresponding electrical signals and to process the electrical signals and display corresponding incremental positional indicators.

Abstract: A lock assembly for securing a trailer including a ball hitch, a lock housing, a lock washer and a nut. The lock housing is placed over the lock washer and nut to prevent the nut from turning. A threaded portion of the ball hitch is placed through a hole in the lock housing and through the lock washer and nut to secure the ball hitch. When a trailer coupler is locked to the ball portion of the ball hitch, the trailer and ball hitch are secure from theft.
