Abstract
An extendible wire guide is slidably fitted at the front of a staple gun tool housing. An easily operated lever switch is linked to the wire guide to enable the wire guide to be deployed or retracted. The lever switch includes an up and a down position corresponding to a retracted and an extended position of the wire guide. The wire guide is resiliently biased, preferably toward the retracted position. The lever switch acts on the wire guide against the bias through a cam action on an upper edge of the wire guide. A bias spring is preloaded in a subassembly of the wire guide and bias spring for simplified final assembly.
Claims18
A fastening tool to attach objects to a work surface, comprising:
- a housing including a top, bottom, rear and front;
- a fastener guide track disposed at the bottom of the housing;
- a striker movable vertically on the housing at a front of the guide track;
- a wire guide disposed at a location of the striker, the wire guide including a stowed position within the tool and a deployed position extended out from the tool;
- a spring, wherein the spring biases the wire guide toward the stowed position;
- and
- a lever switch linked to the wire guide through a cam engagement, wherein a first position of the lever switch allows the wire guide to be in the stowed position under the bias of the spring, and a second position of the lever switch causes the lever switch to press the wire guide to the deployed position against the bias of the spring.
A fastening tool to attach objects to a work surface, comprising:
- a housing including a top, bottom, rear and front;
- a fastener guide track disposed at the bottom of the housing;
- a striker movable vertically on the housing at a front of the guide track;
- a wire guide disposed proximate a location of the striker, wherein the wire guide includes a stowed position within the tool and a deployed position extended out from the tool;
- a lever switch linked to the wire guide through a cam of the lever switch, the cam undergoing an arcuate motion about a lever pivot as the lever switch is moved from a first position to a second position;
- a cam path surface of the wire guide slidably engaging the cam of the lever switch, the cam path surface including a ramp between a first landing and a second landing, the wire guide being in a stowed position when the lever cam is at the first cam path landing, and the wire guide being in a deployed position when the lever cam is at the second cam path landing;
- and
- a spring, wherein the spring biases the wire guide against the lever cam, and moving the lever causes the wire guide to move between the stowed position and the deployed position against the bias of the spring.
