Abstract

An installation tool and related methods are provided. The tool can pull a strip of collated fasteners along a collated fastener path to a guide, where individual fasteners are sequentially separated from the strip and advanced into a workpiece. The tool can include a tension feeder located downstream of the guide. The tension feeder is configured to apply tension to the strip between the guide and a leading end of the strip. The tool can include a driveshaft configured to attach to a conventional drive tool chuck or a drive tool having hexagonal type drive components. The guide can be one piece and replaceable, with a guide body and a guide head. A strip slot can be defined in the same to align a fastener head with a backstop and facilitate entry of a fastener shank in a feed slot. Related methods of use are provided.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A method of installing a fastener in a workpiece comprising:
pulling on a strip of collated fasteners at a location downstream of a guide defining a bore, the strip including a carrier and a plurality of fasteners;
advancing a first fastener from the plurality of fasteners through the bore and into a workpiece; and
attaching a tension feeder to only a leading end of the carrier so that the tension feeder can pull on the carrier at only the leading end of the carrier at the location downstream of the guide,
wherein a trailing end of the carrier remains upstream of the guide during the pulling step;
wherein a portion of the carrier between the trailing end and the guide is under no tension during the pulling step and during the advancing step,
wherein the tension feeder remains attached to the leading end of the carrier until the trailing end is adjacent the guide.

2. The method of claim 1 comprising:
aligning the first fastener with the bore by engaging a head of the first fastener against a backstop of the guide and pulling on a shank of the first fastener with the carrier so that a tip of the first fastener swings into alignment with the bore.

3. The method of claim 1 comprising:
applying no force, from any location upstream of the guide, to the strip such that the strip is only moved via the pulling on the strip at the location downstream of the guide.

4. The method of claim 1 comprising:
securing a tension feeder to the carrier at only a leading end of the strip so that the tension feeder moves with the leading end; and
passively guiding a trailing end of the carrier upstream of the guide.

5. The method of claim 4 ,
wherein the carrier includes a leading edge and a trailing edge, and a downstream portion located downstream of the bore, and an upstream portion located upstream of the bore,
wherein the tension feeder is joined with the carrier near the leading edge,
wherein the tension feeder performs the pulling step,
wherein the tension feeder is the only part of the tool that moves the carrier past the bore,
wherein the carrier includes right and left sides,
wherein the right and left sides are void of notches along a continuous majority of a length of the carrier.

6. A method of installing a fastener in a workpiece comprising:
pulling on a strip of collated fasteners at a location downstream of a guide defining a bore, the strip including a carrier and a plurality of fasteners;
advancing a first fastener from the plurality of fasteners through the bore and into a workpiece;
attaching a leading end of the carrier at a location downstream of the guide to an elongated member; and
rolling the elongated member onto itself to form an elongated member roll; wherein a trailing end of the carrier remains upstream of the guide during the pulling step; wherein a portion of the carrier between the trailing end and the guide is under no tension during the pulling step and during the advancing step.

7. The method of claim 6 ,
wherein the elongated member is joined with a tensioner spring,
wherein the tensioner spring retracts the elongated member toward the tensioner spring.
