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 |
20120318695 | THEFT-RESISTANT PRODUCT PACKAGING AND RELATED METHOD - Theft-resistant product packaging includes a front shell having a matrix of cut-resistant strands disposed within or adjacent to a plastic substrate, and a back cover secured to and disposed relative to the front shell so as to form a cavity configured to contain a product therebetween. The cut-resistant strands may be formed of metal, fiber or fabric forming a matrix of cut-resistant strands which are overlayed, weaved or twisted with respect to one another. The cut-resistant strands may be disposed in a grid so as to form squares, rectangles, diamonds or parallelograms which are welded, glued or bound at the points of intersection | 12-20-2012 |
20120322638 | METHOD FOR FORMING THEFT-RESISTANT PRODUCT PACKAGING - A method for manufacturing theft-resistant product packaging includes the steps of (1) providing a matrix of cut-resistant strands, (2) adhering the matrix to a plastic substrate to form a theft-resistant material, (3) forming a front shell from the theft-resistant material including a cavity for holding a product therein, and (4) securing the front shell to a back cover so as to enclose the product therebetween. | 12-20-2012 |
20130118322 | QUICK CHANGE TOOL - A quick change tool and the method for using it are disclosed. The tool is configured to enable a user to select between multiple head types within the same tool without the need to physically remove the head from the hand tool. The tool may comprise a work member having more than one head configuration thereon, which is rotatably coupled to a shaft, and a sleeve that is axially movable relative to the shaft. As the sleeve is moved axially relative to the shaft, a biasing member on the sleeve engages the work member causing it to be rotated upon the shaft to alternatively position one or the other of at least two functional heads of the work member to be placed into a working position of the tool. | 05-16-2013 |
20130276312 | 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. | 10-24-2013 |
20140124401 | THEFT-RESISTANT PRODUCT PACKAGING AND RELATED MANUFACTURING PROCESS - Theft-resistant product package includes a front shell having a security pattern of thickened plastic areas or of cut-resistant strands on a plastic substrate and a back cover secured to and disposed relative to the front shell. An alternative theft-resistant product package includes an enclosed packaging structure having front and back surfaces spaced apart by at least one side wall around the perimeter of the front and back surfaces, and a plurality of indentations disposed in the at least one side wall. A process for manufacturing theft-resistant product packaging includes the steps of forming a theft-resistant security pattern of thickened plastic areas on a plastic substrate, shaping the plastic substrate to form a cavity, and securing the plastic substrate to a back cover. | 05-08-2014 |
20140298661 | TWO STAGE FORCE MULTIPLIER TIN SNIPS - Two-stage force multiplier tin snips are provided which have a pair of cutting blades and associated tangs, both being pivotable about a cutting axis. Each respective tang is coupled to a pair of handles by a pair of respective tang pins. The handles are pivotably attached to one another about an adjustable handle axis. The handle axis is adjustable between an upper position and a lower position to provide a mechanism for changing a force multiplier of the cutting blades. The handle axis may be a sliding axis disposed in longitudinal slots on the handles. The handle axis may also be upper and lower fixed pins that are slidable in lateral slots. | 10-09-2014 |
