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

What is claimed is:

1. A method of installing a fastener comprising:
pulling on a strip at a first location downstream of a guide defining a bore, the strip including a plurality of fasteners, each fastener defining a hexalobular drive hole, the strip engaged at a leading end thereof with a pin extending through the strip; and
sequentially advancing the plurality of fasteners through the bore and into a work piece with a drive element that extends through the strip while rotating,
wherein a tension feeder automatically pulls the strip during the pulling step through the guide, the tension feeder including a feeder element,
wherein the feeder element engages the strip at the first location,
wherein the feeder element moves with the strip at the first location, farther and farther away from the guide with each succeeding fastener advanced from the plurality of fasteners,
wherein the feeder element is joined with the pin,
wherein the strip is pulled with the pin as the pin moves along and adjacent a rear surface of a frame.

2. The method of claim 1 , comprising:
guiding the strip with a guide channel distal from and upstream of the bore; and
sequentially guiding the plurality of fasteners into a feed slot that is upstream of the bore and downstream of the guide channel.

3. The method of claim 1 ,
wherein the drive element includes a hexalobular drive head that enters the hexalobular drive hole before a first instance of said advancing step.

4. The method of claim 1 , comprising:
moving the hexalobular drive head downward through the strip and into the bore;
moving the hexalobular drive head beyond the bore while engaging the hexalobular drive hole.

5. The method of claim 4 , comprising:
retracting the hexalobular drive head from the bore upward out of a hole in the strip.

6. The method of claim 1 , comprising:
maintaining tension on the strip while the drive element is projecting through the strip so that the drive element through the strip prevents the strip from advancing to place a second fastener adjacent the drive element.

7. The method of claim 6 ,
wherein the second fastener remains in a feed slot adjacent and leading into the bore until the drive element exits the strip,
wherein the second fastener moves over the bore after the drive element exits the strip.

8. The method of claim 1 ,
wherein the strip is pulled with a spring disposed inside the frame.

9. The method of claim 1 ,
wherein the strip is pulled automatically with the tension feeder including the pin and the feeder element, along a slot downstream of the guide.
