Abstract
A cutter guard device is adapted for use in a belt saw machine, and includes a stationary hinge leaf formed with a first knuckle unit, a movable hinge leaf formed with a second knuckle unit, and a hinge pin extending through the first and second knuckle units, thereby permitting rotation of the movable hinge leaf between cutter concealing and cutter exposing positions. The movable hinge leaf is further slidable along the hinge pin between retaining and pivoting positions. The movable hinge leaf is movable between the cutter concealing and cutter exposing positions when disposed in the pivoting position on the hinge pin. A retention unit retains releasably the movable hinge leaf in the cutter concealing position when the latter is further disposed in the retaining position on the hinge pin.
Claims7
A cutter guard device for a belt saw machine, said cutter guard device comprising:
- a stationary hinge leaf having a coupling edge formed with a first knuckle unit;
- a movable hinge leaf having a coupling edge formed with a second knuckle unit;
- a hinge pin extending through said first and second knuckle units, thereby permitting rotation of said movable hinge leaf relative to said stationary hinge pin about said hinge pin for movement between a cutter concealing position and a cutter exposing position;
- said movable hinge leaf being further slidable relative to said stationary hinge leaf along said hinge pin between a retaining position and a pivoting position;
- said movable hinge leaf being movable between the cutter concealing and cutter exposing positions when
- said movable hinge leaf is disposed in the pivoting position on said hinge pin;
- and
- a retention unit capable of retaining releasably said movable hinge leaf in the cutter concealing position when said movable hinge leaf is further disposed in the retaining position on said hinge pin.
