20080250652 | SELF LOCKING KNIFE AND SHEATH - A knife and sheath that includes a spring element as part of the handle with a pin that engages a slot in the sheath so as to lock the knife and sheath together. The knife and sheath are unlocked by biasing the spring element towards the center line of the knife, thereby disengaging the pin from the slot. | 10-16-2008 |
20110308092 | Slider for a cutter - A slider has an upper sliding element, a lower sliding element and a resilient tab. The upper sliding element has two protrusions laterally formed on and protruding from the upper sliding element. Each protrusion has an inclined pushing surface. The lower sliding element is combined with the upper sliding element and has a chamber and two through hole. The through holes are defined in the lower sliding element at positions corresponding respectively to the inclined pushing surfaces of the protrusions and communicate with the chamber. The resilient tab is held in the chamber and has two legs protruding inward from two ends of the resilient tab. Each leg has an engaging end extending out from one of the through holes in the lower sliding element and abutting with the inclined pushing surface of a corresponding one of the protrusions on the upper sliding element. | 12-22-2011 |
20120011728 | UTILITY KNIFE AND FASTENER THEREOF - A utility knife includes a handle and a connector member. The handle includes a first handle portion and a second handle portion. The connector member is constructed and arranged to releasably connect the first handle portion with the second handle portion. The connector member includes a head portion and a shaft portion extending from the head portion. The head portion includes finger engaging portions extending outwardly for engagement by the fingers of a user, and a groove disposed on a surface of the head portion that is adapted to receive a tool. The connector member is constructed and arranged to be rotated either by engaging the tool in the groove or by manually moving the finger engaging portions. The connector member is constructed and arranged to remain attached to the first handle portion if the first handle portion is separated from the second handle portion. | 01-19-2012 |
20120317820 | Safety Locking Mechanism For A Utility Knife - A safety mechanism for a utility knife is provided to prevent more than one retraction of the blade shield for each trigger actuation. A separable linkage extends between an actuator and a strut, and has a seat member and a deflecting member that are linked together when the actuator is not depressed and the strut is in the safety position blocking the retraction of the shield. The separable linkage is configured to transmit the pressing action of the actuator to the strut to disengage it from the bracket. The separable linkage is configured to delink as the shield retracts. If the actuator continues to be pressed in after the shield returns from being retracted, the safety mechanism prevents relinking of the seat member and the deflecting member, due to the deflecting member being deflected away from the seat member in a substantially longitudinal direction. | 12-20-2012 |
20130205599 | SLIDER FOR A CUTTER - A slider has an upper sliding element, a lower sliding element and a resilient tab. The upper sliding element has two first engaging segments disposed on an inner side of the upper sliding element. The lower sliding element has two second engaging segments disposed on an outer side facing the inner side of the upper sliding element and engaging the first engaging segments. A tab holding base is formed on and protrudes from the outer side of the lower sliding element and has a chamber defined in the tab holding base. The resilient tab is held in the chamber in the lower sliding element and has two legs. Accordingly, a slider having a structure in a closed condition is provided to prevent objects from entering into the chamber to interfere the operation of the resilient tab and the operation of the slider is smooth. | 08-15-2013 |
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 |
20130283622 | HAND-HELD ELECTRIC CUTTING MACHINE - Provided is a hand-held electric cutting machine having excellent spark control capability, high stability, good usability and high versatility. A unit having: a first guard which covers a part of a disc-shaped cutting tool; a second guard which covers a part of the disc-shaped cutting tool and is rotatably attached to the first guard; a movable guard which is rotatable around outer peripheries of the first guard and the second guard, covers a part of the disc-shaped cutting tool, and is attached on the second guard; and a protector which covers an outside of the movable guard and is attached on the second guard, is attached to a hand-held electric tool serving as a driving source. | 10-31-2013 |
20140144027 | GRIP-TYPE CUTTER KNIFE - The present invention is directed to a cutter knife body having a grip portion, wherein the grip portion comprises a trigger lever, a cutting blade provided on an end of the cutter knife body, a pin rotatably supporting the cutting blade in the cutter knife body, a locking member placed in an opening formed in the cutter knife body, and a pair of cutting blade protector flanges, each protector flange being disposed on a side of the cutting blade, wherein each of said pair of cutting blade protector flanges has an outward protrusion from a surface of the flange, the grip type cutter knife characterized by further comprising: a pair of springs located between the pin and each of the outward protrusion. from the flange surface, wherein the pair of flanges is slidably supported in the cutter knife body by the pin and the pair of springs. | 05-29-2014 |
20150033562 | CARD HOLDER WITH BUILT IN CUTTER - A card holder with a built in seatbelt cutter is provided. The present invention may include a back plate with an outer perimeter formed by a top end, a bottom end, a first side, and a second side. The back plate may include a cutout portion formed through the outer perimeter and into the back plate. The present invention may further include a cutter blade attached to the back plate and disposed within the cutout portion. The present invention may further include a card receptacle attached to the back plate that is sized to receive and secure a card within. | 02-05-2015 |
