Abstract
A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.
Claims20
A magazine for a fastening device, comprising:
- a pusher assembly adapted to have an engaged state and a retracted state;
- the pusher assembly having a pusher assembly knob and a pusher;
- the pusher adapted to contact a fastener and to impart a force upon the fastener in a direction toward a nose end of the magazine when the pusher assembly is in the engaged state;
- a recess into which the pusher is reversibly retracted at least in part when the pusher assembly knob is moved to reversibly retract the pusher to achieve the retracted state;
- a detent adapted to reversibly maintain the pusher assembly in the retracted state;
- and
- the pusher assembly knob adapted to reversibly latch to the detent.
A fastening device, comprising:
- a nosepiece adapted to receive a fastener from a magazine;
- a power source adapted to power a fastener driving mechanism which can drive the fastener into a workpiece when triggered;
- a pusher assembly adapted to have an engaged state and a retracted state;
- the pusher assembly having a pusher assembly knob and a pusher;
- the pusher adapted to contact a fastener and to impart a force upon the fastener in a direction toward the nosepiece when the pusher assembly is in the engaged state;
- a recess into which the pusher is reversibly retracted at least in part when the pusher assembly knob is moved to reversibly retract the pusher to achieve the retracted state;
- and
- a detent adapted to reversibly maintain the pusher assembly in the retracted state.
A method for loading fasteners into a magazine of a fastening device, comprising the steps of:
- providing a magazine having a pusher assembly adapted to have an engaged state and a retracted state, the pusher assembly having a pusher assembly knob connected to a pusher, the pusher adapted to contact a fastener and to impart a force upon the fastener in a direction toward a nose end of the magazine when the pusher assembly is in the engaged state;
- providing a recess of the magazine into which the pusher is reversibly retracted at least in part when the pusher assembly knob is moved to reversibly retract the pusher to achieve the retracted state;
- providing a detent of the magazine adapted to reversibly maintain the pusher assembly in the retracted state, and the pusher assembly knob is adapted to reversibly latch to the detent;
- reversibly retracting the pusher assembly into the retracted state;
- maintaining the pusher assembly in the retracted state;
- feeding one or more fasteners to the track;
- and
- engaging the pusher assembly from the retracted state into the engaged state.
