Sliding Blade Patents (Class 30/162)
  • Patent number: 12005594
    Abstract: A pocket knife includes a chassis, a surface defined by the chassis, and a blade having a retracted position in which the blade is locked inside of the chassis and a deployed position in which at least a portion of the blade is locked outside of the chassis. An actuator is slidingly engaged with the chassis to reposition the blade between the retracted and deployed positions. A stop pin is connected to the blade. An end of the stop pin extends a predetermined distance from the blade to engage with the surface defined by the chassis when the blade is in the deployed position to prevent movement of the blade with respect to the chassis.

  • Patent number: 11999070
    Abstract: A pocket knife includes a chassis that defines a cavity. A blade having a cutting edge has a retracted position and a deployed position. A slider inside the cavity has a first surface opposed to a second surface. A front operator is inside the cavity, and the slider engages with the front operator to move the blade to the deployed position. A rear operator is inside the cavity, and the slider engages with the rear operator to move the blade to the retracted position. A spring connects the front operator to the rear operator along the first surface of the slider. A longitudinal recess is defined in the chassis. A first boss extends radially from at least one of the front operator or the rear operator and slidingly engages with the longitudinal recess in the chassis.

  • Patent number: 11919186
    Abstract: A retractable cutter comprises a plunger that can be pressed to an on-position for pushing a thrust device of the cutter to guide a blade via a cam piston cartridge through a blade guide and partially outside a bottom retainer to expose the tip of the blade from a housing of the retractable cutter. In this on-position, a spring mechanism of the retractable cutter is engaged between the bottom retainer and the cam piston cartridge to provide a spring force for preventing the blade from extending any further. When the plunger is pressed to an off-position, the thrust device is positioned in such a way to enable the spring mechanism to rebound to its original position for retracting the blade back into the housing.

  • Patent number: 11679517
    Abstract: A utility knife includes a blade, a housing to store the blade, an actuator, and a pinion gear to deploy the blade. The pinion gear includes one or more sets of teeth that are engaged with a fixed rack of the housing and a sliding rack of the blade holder. The pinion gear is also coupled to the actuator, which is configured to linearly translate the pinion gear. As the pinion gear linearly translates between front and back ends of the housing, the pinion gear rotates due to its engagement with the fixed rack. The further engagement between the pinion gear and the sliding rack causes the sliding rack to advance in the same linear direction as the pinion gear by a distance that is greater than the linear distance traversed by the pinion gear, thereby advancing or retracting the blade connected to the blade holder.

  • Patent number: 11376753
    Abstract: A utility knife includes a hollow handle having a slot and an opening at each end. A razor is slidable between each end of the handle and may protrude at each opposing end for cutting use. The razor is mounted to a shuttle which includes a tab that is positioned within the slot. The user may use the tab to slide the shuttle and the blade within the handle between the two ends, as desired. A U-shaped blocking component is pivotally attached to the handle and is used to block sliding movement of the tab beyond a midpoint of the handle to prevent the razor protruding into the user's hand. The user must unlock the blocking element to safely allow the shuttle to be slid past.

  • Patent number: 11357535
    Abstract: A scalpel has a handle (1) and a blade carrier (2) movable within a longitudinally extending cavity therein between an operative position in which a blade (5) on the blade carrier is exposed for use and an inoperative retracted position. A manually operable slider (4) moves the blade carrier (2) that has a catch face (21) directed rearwards in the operative position. The catch face partially aligns with a stop face (22) provided on the handle (1) in the normal operative position of the blade carrier such that force exerted on a blade carried by the blade carrier in the direction of the length of the handle causes engagement of the catch face with the stop face to arrest movement of the blade carrier into the cavity. Transverse biasing of the blade carrier (2) is overcome by pressure exerted on the slider (4) to retract the blade carrier (2) into the handle with the catch face (21) passing the stop face (22).

  • Patent number: 11358292
    Abstract: A cutter apparatus includes a housing with a blade carrier configured for holding a blade, and a handle coupled to the housing via an engagement interface configured to allow a user of the cutter apparatus to selectively interfit together the housing and the handle in multiple different cutter apparatus configurations, wherein the engagement interface includes a coupler configured to permit the housing and the handle to be repositioned further apart in a housing/handle reconfiguring mode in which the coupler permits the handle to be rotatably repositioned in relation to the housing or vice versa while substantially limiting longitudinal movement of the housing relative to the handle.

  • Patent number: 11351683
    Abstract: A utility knife comprises a housing (1), a blade carrier (2), a blade (3), a position control component (4) and a safety control component (5); a positioning direction (B) is defined at an angle to the sliding direction (A) of the position control component (4), the first blocking position (141) is farther away from the positioning portion (42) of the position control component (4) than the rest areas of the slide rail (13) except the first blocking position (14). In this way, in addition to blocking position shift, the position control component can also be used for contact-fitting with the blade carrier to determine whether the blade carrier can slide forward independently. Therefore, the utility knife has fewer components, resulting in low material cost, fewer assembly steps, convenient and time-saving assembly process, and the components are not easy to lose.
