Pivoted Part Patents (Class 30/330)
  • Patent number: 11577420
    Abstract: A quick-change cutting assembly includes a base having a support surface for supporting a cutting blade, a clamping arm having a clamping surface, a spring interposed between the base and the clamping arm, and a pivot defining a pivot axis between the spring and the clamping surface that couples the clamping arm to the base. The spring biases the clamping surface toward the support surface and a cutting blade therebetween. The clamping arm is pivotable between a closed position where the clamping surface is parallel to the support surface and an open position removed from the closed position where the clamping surface is spaced further from the support surface. The cutting assembly further includes a locking pin transverse the direction of biasing action of the spring that connects the clamping arm to the base to prevent the clamping arm from pivoting relative to the base when in the closed position.

  • Patent number: 11426888
    Abstract: Presented embodiments of the handheld cutting tool are capable of cutting in one of two ways: with the cutting edge of the blade only so as to minimize damage to objects not intended to be cut or, alternately, with the point of the blade as with more typical knives. The tool is comprised predominantly of a handle body, a blade holder and a rotational control assembly for allowing the blade holder to rotate. The blade holder holds either a replaceable isosceles trapezoid utility blade or replaceable single edge razor blade and has, in some embodiments, a portion that isolates parts of the blade from objects not intended to be cut. The rotational control assembly enables the blade holder to rotate between retracted and a plurality of extended positions thus permitting the blade holder to deploy the blade at various angles to facilitate proper cutting of materials.

  • Patent number: 8978257
    Abstract: A utility knife employing a blade having multiple cutting portions, and a housing for quickly and simply swapping out one cutting portion for another. In a preferred embodiment, a six-cutting-portion featured blade is employed. Each point of the six-cutting-portion featured blade features two distinct cutting portions, for a total of six cutting portions located on a single blade. The blade can be rotated about a central axis to expose new cutting portions as old portions wear and dull. In another embodiment, a single-edged blade featuring two cutting faces is housed in a knife handle. The blade can be flipped when the first portion is dull or worn to expose a second cutting face. The handle may optionally include a storage space for storing additional blades.

  • Patent number: 6675485
    Abstract: An artistic knife with adjustable handle includes a straight handle which is combined with a pair of first and second halves, a head rotatably gripped by the straight handle and having a blade on front end and an annular ring on rear end sleeved on a tubular projection of the first half. The annular ring has an inner flange in which a plurality of pairs of mortises are symmetrically formed. A positioning member disposes into the tubular projection and biased by a spring and has a protrudent surface engaged within a circular through hole of the second half through the annular ring and a large tenon and a small tenon on opposing outer peripheries respectively engaged with the mortises. Thereby, press the positioning member inward to enable the head to rotate a certain degree of angle between the head and the straight handle. Then release the positioning member which controls the movement of the head.

  • Patent number: 6574872
    Abstract: A cutting device wherein an illustrated embodiment can have two handles that are pivotable about a pivot axis between an open and a closed position while being permanently fastened together. A hand-activated securing and releasing mechanism pivots around the pivot axis and moves between a securing position rigidly securing the handles together in the closed position and a releasing position permitting the handles to freely move between the open and closed position. In the open position, the primary knife blade and its spares can be accessed. A one-piece gripping member can be secured to the knife to overlap both handles.

  • Patent number: 6532670
    Abstract: A utility knife has a flat blade formed with at least one throughgoing hole, a housing member forming a seat adapted to receive the blade, and a retainer member engageable with the blade on the seat. A pair of respective pivot elements on the housing and retainer members allow pivoting of the retainer member between a closed position engaging the blade and holding it against the seat and an open position exposing the blade and permitting its removal from the seat. Respective threadedly interengageable holding elements including a threaded screw on one of the members extending through the hole of the blade and a nut on the other of the members secure the retainer member in the closed position. The threaded screw is fixed in the housing member and has a threaded shaft projecting up from the seat. The nut is rotatable on the retainer member. The retainer member is formed with a large-diameter recess receiving the nut with radial play.

  • Patent number: 6131292
    Abstract: A utility knife has two shells that are pivoted or hinged to each other at one end to permit opening the knife handle formed by the shells for insertion or replacement of a knife blade. The two shells are interlocked with each other by a latching mechanism, including a stationary section in one shell and a rotatable section in the other shell. The rotatable section has a spring elastic bail that engages the stationary section and an operating member for disengaging or engaging the rotatable member from the stationary stop bar. In the interlocking position the operating member is recessed in a recess in the surface of one of the shells. When the knife is used, the operator's hand provides additional safety by keeping the operating member in its recess and thus the two shells interlocked.

  • Patent number: 6026575
    Abstract: A utility knife handle including a first body, or first shell, adjustably mated to a second body, or second shell, to form a blade holding portion and a blade storing portion. The first and second bodies have mating beveled surfaces adapted to align the first body with the second body when they are joined. In the preferred embodiment the first body is connected to the second body by a control knob adapted to allow for linear and pivotal adjustment between the first and second bodies. The utility knife handle is adjustable between an open position in which the holding portion and the storing portion allow the removal of any blades therein, an intermediate position in which the holding portion prevents removal of any blades therein and allows for positional adjustment of blades therein and the storing portion prevents the removal of any blades therein, and a closed position in which the holding portion prevents movement of any blades therein and the storing portion prevents the removal of any blades therein.
