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.
Claims17
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;
- 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 pusher guide track which guides the pusher, the pusher guide track configured to reversibly guide the pusher along at least a portion of a nail track to achieve the retracted state in which the pusher is configured to occupy said recess at least in part;
- and
- a detent adapted to reversibly maintain the pusher assembly in the retracted state;
- wherein the pusher assembly knob is adapted to reversibly latch to the detent;
- wherein the pusher is configured to occupy at least a portion of a nail track when the pusher assembly is in the engaged state, and
- wherein the pusher has a portion 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 fastening device, comprising:
- a nosepiece adapted to receive a fastener from a magazine;
- a power source adapted to power a fastener driving mechanism to 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;
- a pusher guide track which guides the pusher along at least a portion of the nail track, the pusher guide track configured to reversibly guide the pusher to achieve the retracted state in which the pusher is configured to occupy said recess at least in part;
- 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;
- wherein the pusher is configured to occupy at least a portion of a nail track when the pusher assembly is in the engaged state;
- and
- wherein the pusher has a portion 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.
