| 20080250650 | UTILITY KNIFE - The utility knife includes a handle and a replaceable blade having a lock retention notch. A blade lock mechanism includes a blade lock associated with the handle which automatically engages the lock retention notch on insertion of the blade into the handle. The blade lock mechanism further includes a means for manually disengaging the blade lock from the lock retention notch in order to remove the blade from the handle. | 10-16-2008 |
| 20090014934 | RATCHETING C-CLAMP - A one-handed ratcheting C-clamp is provided. The C-clamp incorporates a spring loaded handle mechanically coupled to a ratcheting mechanism. The ratcheting mechanism has a plurality of gear teeth that engage the threads of a corresponding rod disposed through a hole formed in one section of the C-shaped C-clamp. The handle rotates the bidirectional ratchet such that the threaded rod is lowered or raised within the hole of the C-shaped C-clamp. A button located in the side of the handle may release the ratchet mechanism pawl to provide axial sliding engagement of the rod to a corresponding work piece. The handle and corresponding ratchet mechanism secure the rod against the work piece. Further tightening engagement of the work piece is accomplished via a lever located on a top portion of the rod. | 01-15-2009 |
| 20100175267 | UTILITY KNIFE INCLUDING A LOCKING MECHANISM AND/OR RATCHETING MECHANISM - A utility knife includes a handle and a pivotably connected blade retainer for retaining a blade. An external, symmetrically toothed gear is fixed relative to one of the handle or the blade retainer, and a locking mechanism is associated with the other. The locking mechanism cooperates with the gear to lock the blade retainer in one of a plurality of fixed positions and includes pawls located in channels having converging ends. A manually actuable release mechanism is associated with the locking mechanism for unlocking the blade retainer to permit pivotal movement. Furthermore, a manually actuable blade release mechanism is associated with a blade locking mechanism contained in the blade retainer, for locking and releasing the blade when exchanging a dull blade for a replacement blade. | 07-15-2010 |
| 20110001283 | QUICK RELEASE BENCH VISE SYSTEM - A quick release vise includes a first and second jaw moveable relative to the first jaw, and a threaded shaft rotatably fixed to the second jaw. A shaft receiver is fixed relative to the first jaw and includes a boss and a boss cover that is moveable relative to the boss. The boss and the boss cover have channels which cooperatively define an at least partially threaded shaft-receiving bore. The boss cover is moveable between a first position wherein the threads of the shaft engage threads within the shaft-receiving bore, and a second position wherein the threads of the shaft are disengaged from the threads within the shaft-receiving bore. | 01-06-2011 |
| 20110041344 | SELF LOADING UTILITY KNIFE - A self-loading utility knife including an elongate handle having an internal chamber defining an axis and at one end is flat aperture for the passage of an active blade. The flat aperture defines a cutting plane extending through said handle along the axis. A blade-holder is slidably mounted in the chamber for movements in directions along the axis and is adapted to secure a single active blade for movement through the aperture when the blade holder is in the extended position. A blade-holder release button is coupled to the blade holder and is slidingly movable relative to the handle to move blade holder between retracted and extended positions. The handle has a blade compartment which is open to the chamber and can receive a stack of spare blades when a cover to the compartment is opened and blades can be shifted transversely relative to the axis into the chamber. The blade holder is provided with a recess having a depth no greater than the thickness of one blade to allow at least a portion of a single blade to be received in a retaining relationship within the recess to cause an end-most blade in the stack to be received within said recess to follow the movements of the blade holder. A spring biases the blades in the blade compartment inwardly in the direction of the blade holder. A blade releasing disc on the blade holder selectively locks a blade to the blade holder when the blade holder is in the extended position. The blade holder only receives a single blade within the recess. A belt clip s provided on the compartment cover. | 02-24-2011 |
