1. Field of the Invention
The present invention relates generally to tool pouches and retractable tool lanyards. Particularly, the present invention relates to a tool pouch with a retractable tool lanyard.
2. Description of the Prior Art
The use of hand tools (i.e. hammers, screw drivers, pliers, ratchets, levels, flashlights, tape measures, etc.) when working in overhead situations have the potential to be articles that can cause damage or injury. In these working conditions the hand tools if dropped could cause a hazard to personnel and/or equipment located beneath where the work is being performed.
There are large numbers of conventional tool belts that are used to carry hand tools. These types of tool belts when used in overhead situations will normally include a fastening feature that will lock the specific tool into the tool pouch when it is not being used. When the tool is needed to perform a specific task, the tool pouch is unfastened and the tool is removed from the tool pouch. While in use, if the tool is mishandled, bumped, or jarred, it can become dislodged from the user's hand and free to fall to whatever is beneath the worker. This normally does not pose a hazard except when there are personnel working or even passing by the area located beneath the worker's platform (i.e. when erecting scaffolding, working in elevated situations, etc.).
Another hazardous circumstance can arise when working above vital plant equipment. If a tool is dropped into an area where there is vital equipment, the dropped tool could cause severe damage to the equipment below. There have been many attempts to overcome these hazards with dropped tools. Makeshift lanyards using rope and/or string with duct tape as a fastening means have been used to create wrist lanyards and tethers to keep a specific tool attached to the users arm or wrist.
More elaborate lanyards have also been manufactured for the prevention of dropped tools. One of the simpler models uses webbing with a hook and loop fastener so that it can be adjusted and tightened around the users wrist. With a D-ring sewn into the webbing, one end of a tether can be attached to the wrist lanyard and the other end attached to the tool using one of many available fasteners.
Although there are more elaborate tooling lanyards available on the market than disclosed above, there is still a high percentage of dropped tools that occur. The disadvantage of the prior art tooling lanyards is due to the inconvenience and cumbersome methods of detaching and reattaching different tools to the lanyards.
It is an object of the present invention to provide a retractable coil lanyard device. It is another object of the present invention to provide a retractable coil lanyard device mountable in a tool pocket of a tool pouch.
The present invention achieves these and other objectives by providing in one embodiment a retractable coil lanyard device that includes a tubular housing having a first housing end and a second housing end and a resiliently extensible and retractable coil disposed within the tubular housing. The tubular housing has a predefined length where, when placed within a tool pocket of a tool pouch, the first housing end is adjacent a bottom of the tool pocket and the second housing end is adjacent a top of the tool pocket. The coil has a coil body, a first coil end and a second coil end. The coil body is formed from a cord having a predefined diameter where the cord is formed into a helix. The first coil end is retained at the first housing end and the second coil end extends a predefined distance beyond the second housing end and is configured for attaching to a hand tool.
In another embodiment of the present invention, the retractable coil lanyard device includes a tool pocket retaining member. The tool pocket retaining member is securely attached adjacent to and extending away from the first housing end of the tubular housing.
In a further embodiment of the present invention, the first coil end of the retractable coil lanyard device has an enlarged end portion. The first housing end of the tubular housing is a closed end having an aperture with a diameter larger than the diameter of the cord diameter of the coil but smaller than the enlarged end portion of the first coil end where the aperture receives the first coil end therethrough.
In another embodiment of the present invention, the first coil end of the retractable coil is rotatably disposed in the aperture of the first housing end.
In still another embodiment of the present invention, the retractable coil lanyard device includes a band fastener disposed around the tubular housing adjacent the first housing end and securely fixing the tool pocket retaining member to the coil housing.
In yet another embodiment of the present invention, the first housing end of the tubular housing has a cap forming the closed end.
In another embodiment of the present invention, the retractable coil lanyard device includes a spacer disposed around the coil at the first coil end between the first housing end and the enlarged end portion of the first coil end.
In another embodiment of the present invention, there is disclosed a tool pouch and retractable lanyard system. The system includes a tool pouch having a plurality of tool pockets and a retractor coil lanyard device. The retractor coil lanyard device has a tubular housing and a helical, resiliently extensible and retractable coil disposed within the tubular housing. A first coil end of the retractable coil is attached to a first housing end and a second coil end extends from a second housing end. The second coil end is configured for attachment to a hand tool. The tubular housing is configured for insertion and retention into one of the plurality of tool pockets.
In a further embodiment of the present invention, there is disclosed a method of making a retractable coil lanyard. The method includes providing a tubular housing having a first housing end and a second housing end, forming a helical, resiliently extensible and retractable coil having a coil body, a first coil end and a second coil end, and disposing the helical coil within the tubular housing and attaching the first coil end to the first housing end. The tubular housing has a predefined length that, when placed within a tool pocket of a tool pouch, the first housing end is adjacent a bottom of the tool pocket and the second housing end is adjacent a top of the tool pocket. The coil body is formed into a helix from a cord having a predefined diameter while the first coil end is configured for attachment to the first housing end and the second coil end configured to extend out of the second housing end and to attach to a hand tool.

In the preferred embodiment, a cap 30 coupled to first housing end 22 forms the closed end. Cap 30 may either be inserted into or over and around first housing end 22. As illustrated, cap 30 has a cap body 31 and a cap end 35. Cap end 35 has a lateral flange 36 that extends away from cap body 31. Cap body 31 has an outside body surface 31a and is sized to have a sliding fit against the inside surface 27 of tubular housing 20 at first housing end 22. Cap body 31 may be secured or removably secured to first housing end 22 such as by threads, adhesives or a friction fit with first housing end 22. A friction fit of cap 30 is preferred because it provides for easier and quicker assembly of cap 30 to tubular housing 20. Cap end 35 has an aperture 38 with a cross-sectional area greater than the cross-sectional area of the cord material used to form retractable coil 20 so that first coil end 44 passes therethrough. It is contemplated that cap 30 may be a solid component with a single longitudinal conduit in cap 30 equal to the size of aperture 38. Alternatively, cap body 31 may have an inside surface 31b defining a tubular space with a cross-sectional area that is larger than the cross-sectional area of aperture 38. When circular components are used, this means that the inside diameter of cap body 31 is larger than the diameter of aperture 38. It is preferred to have the latter design so that a friction fit may be more easily attained since a thinner wall 37 in cap body 31 provides some limited flexibility against the inside surface of first housing end 22. This alleviates the need to have very exacting friction fit dimensions for joining cap 30 to first housing end 22. It is also preferred to have a tapered surface 34 between the inside surface 31b and aperture 38.

Making the retractor coil lanyard device 10 will not be described. A tubular housing 20 is provided that has a predefined length. The length is selected so that, when placed within a tool pocket 112 of a tool pouch 110, a first housing end 22 is adjacent the pocket bottom 113 and a second housing end 24 is adjacent a pocket top 114 of tool pocket 112. A resiliently extensible and retractable coil 40 is formed to have a coil body 42, a first coil end 44 and a second coil end 46. Coil body 42 is formed into a helix from a cord having a predefined diameter. The material and diameter of the cord is selected based on a predefined tensile strength and predefined elasticity of the cord material as well as the weight of the predefined hand tool to which retractable coil 40 is to be attached.
When cap 30 is used to form first housing end 22 into a closed end, first coil end 44 is inserted into cap body 31 and out through aperture 38 of cap end 35. After inserting first coil end 44 through aperture 38, the enlarged end portion 45 is formed so that coil end 44 cannot be pulled back through aperture 38 under normal use. If an optional spacer 48 is used, then spacer 48 is disposed onto first coil end 44 after first coil end 44 is passed through aperture 38 and before enlarged end portion 45 is formed. Second coil end 46 of coil body 42 is inserted into tubular housing 40 at first housing end 22 until cap 35 is adjacent first housing end 22. Cap 35 is then either fixedly attached to or force fitted into first housing end 22. At this point, second coil end 46 and a portion of coil body 42 is extending out of second housing end 24. Second coil end 46 is then formed into a loop 47 and secured to itself using loop fastener 49.
Optional tool pocket retaining member 60 is formed having a retaining member body 62 and a retaining member end 64. When retaining member 60 is made of a web material, retaining member end 64 is most easily made by doubling a portion of retaining member end 64 onto itself and then fastening the doubled portion by stitching or using adhesives or both. Retaining member 60 is placed against housing outer surface 25 at first housing end 22 and band fastener 80 is slipped onto first housing end 22 so that a portion of retaining member 60 adjacent retaining member end 64 is between housing outer surface 25 and band fastener 80. When shrink tubing is used as the material for band fastener 80, the tubing is then heat-shrunk around tubular housing 10 capturing retaining member 60 against tubular housing 10.
When tubular housing 10 is formed to have a closed end with aperture 38 as a unitary structure, then first coil end 44 is inserted into second housing end 24 until first coil end 44 exits aperture 38 at first housing end 22. The remaining steps described above are then performed.
Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
