The tether attachment assembly 22, as shown in
One illustrative method of assembling the tool 10 can be conducted as follows. The tool 10 is provided along with the tether attachment assembly 22. If the fitting 14 of the tool 10 is connected to the body 12, the fitting 14 is disconnected from the body 12 as is well known in the art. Then, the tether attachment assembly 22, including the tether coupling 22, link 24 and collar 30, either provided in pieces or interconnected to any degree, is positioned between the fitting and tool body 12. For example, the tether attachment assembly 22 is arranged such that the first threaded end 26 of the link 24 is inserted through the first aperture 44 of the tether coupling 22 and threaded into the threaded receiving aperture 48 of the tool 10 and the second threaded end 28 of the link 24 is threadably engaged with the first threaded aperture (proximate end 34) of the collar 30. The threaded end 16 of the fitting 14 is threadably engaged with the second threaded aperture 32 of the collar 30. If not already connected, the tether 52 can be secured to the second aperture 46 either via a fastener such as a hook or a carabiner, clipping, tying or the like. The tether 52 can further be secured to the anchor 54 in any known fashion either prior to or after the tether assembly 22 is secured to the tool 10. It will be understood that the order of the aforementioned steps can vary to accomplish the assembled configuration as depicted in
Referring now also to FIGS., 4-5, which illustrate an alternate embodiment of a tool 10′ having an alternate tether attachment assembly 22′. The tool 10′ is largely similar to tool 10 except as explicitly stated. In this embodiment, the collar 30 and link 24 of the previously disclosed tether attachment assembly 22 are omitted as part of the tether attachment assembly 22′. Therefore, the tool 10′ includes a tether attachment assembly 22′ having the tether coupling 42 positioned over the threaded end 16 of nipple fitting 14 proximate the threaded receiving aperture of the tool 10′. As indicated with like reference numbers, all components are identical to that of the previously disclosed embodiment unless explicitly stated.
One method of assembling the tool 10′ can be conducted as follows. The tool 10′ is provided in addition to the tether attachment assembly 22′. If the fitting 14 of the tool 10′ is connected to the body 12, the fitting 14 is removed from the body 12 as is well known in the art. Then, the tether attachment assembly 22′ (i.e. tether coupling 42) is positioned between the fitting 14 and tool body 12. For example, the threaded end 16 of the fitting 14 can be inserted through the first aperture 44 of the tether coupling 42. Then, the fitting 14 is interconnected to the tool body 12. In some embodiments, the threaded end 16 of the fitting 14 is threaded into the receiving aperture 48. If not already connected, the tether 52 can be secured to the second aperture 46 via a fastener such as a hook or a carabiner, clipping, tying or the like. The tether 52 can further be secured to the anchor 54 in any known fashion either prior to or after the tether assembly 22′ is secured to the tool 10′. It will be understood that the order of the aforementioned steps can vary to accomplish the assembled configuration of
