Abstract
A utility knife system for cutting objects The utility knife system has an external handle, a retractable sheath, a retracting mechanism, and an internal housing. The external handle has a sheath sliding track running longitudinally therein and a hinge. The retractable sheath has at least one protrusion that corresponds to the shape of the sheath sliding track, slides within the external handle. The retracting mechanism moves the retractable sheath and locks it in a desired position. The internal housing is received within the retractable sheath and the external handle, and has a hinge attachable to the hinge of the external handle, and a blade retention end opposite of the hinge. The blade retention end receives a cutting blade.
Claims20
A utility knife system for cutting objects safely and effectively, said utility knife system comprising:
- an external handle having a substantially U-shaped configuration, and a sliding track;
- a hinge located at one end of said external handle;
- a retractable sheath having a substantially U-shaped configuration, said retractable sheath being adapted to slide within said external handle along said sliding track;
- a retracting mechanism adapted to move said retractable sheath;
- an internal housing having a pair of support ridges extending out from the bottom thereof to produce a substantially T-shaped configuration, a pivot point attachable to said hinge, and a blade retention end opposite of said pivot point, said blade retention end being adapted to receive a cutting blade, said support ridges being adapted to support said U-shaped external handle when in a closed position thereby allowing said internal housing to be received within said retractable sheath and said external handle;
- and
- an arm having a rotatable attachment point adapted to rotatably connect said arm to said internal housing, and a wedge adapted to secure a cutting blade in said blade retention end when said arm is rotated down.
A utility knife system comprising:
- an external handle having a substantially U-shaped configuration, at least one sliding track running longitudinally therein, and a hinge located at one end of said external handle;
- a retractable sheath having a substantially U-shaped configuration, and at least one protrusion corresponding to the shape of said sliding track, said retractable sheath being adapted to slide within said external handle;
- a retracting mechanism adapted to move said retractable sheath and lock said retractable sheath in position;
- an internal housing having a pair of support ridges extending out from the bottom thereof to produce a substantially T-shaped configuration, a pivot pin attachable to said hinge of said external handle, a blade retention end opposite of said pivot pin, and a cutting blade storage area positioned between said blade retention area and said pivot pin, said blade retention end having a blade seat adapted to receive a cutting blade, said support ridges being adapted to support said U-shaped external handle when in a closed position thereby allowing said internal housing to be received within said retractable sheath and said external handle;
- and
- an arm having a rotatable attachment point adapted to rotatably connect said arm to said internal housing, a wedge adapted to secure a cutting blade in said blade retention end when said arm is rotated down, and an extension positioned to correspond to said cutting blade storage area when said arm is in a down position, said extension being adapted to retain a cutting blade in said cutting blade storage area when said arm is rotated in the down position.
