Abstract
A flexible extension device that can be mounted between a fastener installation tool and a pulling head. The device can flex over a range up to about 45 degrees and can operate under tensile and compressive loads required for installing fasteners. It includes adapters that can mate with a desired type of installation tool and pulling head.
Claims20
A flexible extension device for use with a fastener installation tool having a pulling head, said device comprising:
- a flexible casing capable of withstanding compressive loads applied during fastener installation and having a proximal end and a distal end;
- a flexible housing disposed about said casing and having a proximal end and a distal end;
- a flexible pulling means within said casing and capable of withstanding tensile loads applied during fastener installation, wherein said pulling means is reciprocally slidable lengthwise within said casing and has proximal and distal ends;
- means for coupling said proximal end of said housing to the fastener installation tool;
- means for coupling said distal end of said housing to the pulling head;
- means for joining said proximal end of said pulling means to a pulling device within the installation tool;
- means for joining said distal end of said pulling means to a pulling device within said pulling head;
- means for positioning said pulling means within said casing;
- and
- means for positioning said casing within said housing.
A fastener installation system for installing pull-type fasteners in a workpiece, said system comprising:
- a fastener installation tool;
- a pulling head;
- and
- a flexible extension device positioned between and joined to said tool and said pulling head, wherein said extension device is operable under tensile and compressive forces up to about 5,000 pounds.
A fastener installation system for installing pull-type fasteners in a workpiece, said system comprising:
- a fastener installation tool;
- a pulling head;
- and
- a flexible extension device comprising a flexible pulling means, a flexible casing disposed about said pulling means and capable of withstanding compressive loads applied during fastener installation, and a flexible housing disposed about said casing.
