Description

FALL ARRESTING SYSTEM
FIELD OF THE INVENTION
[001] The present invention relates generally to safety cables for preventing falls, and more particularly, relating to a fall arresting system having a retractable-cable reel and a safety line that has an integrated accessory line.
BACKGROUND OF THE INVENTION
[002] Safety cables of various types for preventing a worker working at elevations from falling to the ground have been developed in the past. More specifically, safety cables heretofore devised and utilized consist of a myriad of designs that have been developed for the fulfillment of numerous objectives and requirements.
While the devices heretofore fulfill their respective, particular objectives and requirements, they do not provide a fall arresting system that includes a retractable-cable reel (e.g., descent control device) and a safety cable having integrated therewith an accessory line as such there exists and need for a fall arresting system, which substantially departs from the prior art, and in doing so provides an apparatus primarily developed for the purpose of controlling descent and having an integrated safety cable and accessory line.
SUMMARY OF THE INVENTION
[003] In view of the foregoing disadvantages inherent in the known types of safety cables now present in the prior art, the present invention provides a new fall arresting system wherein the same can be used for controlling descent and includes an integrated safety line and accessory line.
[004] In accordance with the present invention, an apparatus for fall arresting is provided, that increases safety on a work site by always keeping the safety line tight and away from a worker's feet.
[005] In accordance with the present invention, an apparatus for fall arresting is provided, that integrates a safety line and an accessory line, such as, an electrical power cable or a pneumatic hose, thereby reducing tripping hazards.
[006] In accordance with the present invention, an apparatus for fall arresting is provided, that reduces the risk of tools falling from elevations by integrating a safety line and a tool accessory line together such that the accessory line safely tethers the tool against falling.
[007] In general, in one aspect, a fall arresting system is provided. The fall arresting system includes a fall arresting cable that has a safety line with opposed first and second ends, an accessory line that extends substantially along the safety line between the opposed first and second ends of the safety line, and a sheath that envelops the safety line and the accessory line. The fall arresting system further includes a reel upon which the fall arrest cable is wound.
[008] For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION
[015] FIG.1 representatively illustrates the fall arresting system 10 in use. The user 22 attaches the first end 30 of the fall arrest cable 14 to themself. The fall arrest cable
14 extends away from the user 22 and attaches at the second end 32 to a retractable-cable reel 12. The fall arrest cable 14 includes an integrated accessory line 18 that allows the user 22 to use a pneumatic or electrical tool while attached to the fall arresting system 10 without implementing a trip hazard to the work environment.
[016] FIG. 2 representatively illustrates a cross-sectional view of the exemplary retractable-cable reel 12. The retractable-cable reel 12 includes an exterior housing/casing 36 that envelopes a centrally mounted rotating spool 18 on which the fall arrest cable 14 wraps around. The accessory line 18 exits through a hole in the side of the retractable-cable reel 12 housing/casing 36.
[017] FIG. 3 representatively illustrates one embodiment of the first end 30 of the fall arrest cable 14. The fall arrest cable 14 terminates and attaches to a ring 34 that has the ability to attach to the user. This embodiment demonstrates the fall arrest cable 14 incorporated with an electrical device connection 24 that exits the exterior sheath of the fall arrest cable 14 at some point before the ring 34.

[018] FIG. 4 representatively illustrates one embodiment of the first end 30 of the fall arrest cable 14. The fall arrest cable 14 terminates and attaches to a ring 34 that has the ability to attach to the user. This embodiment demonstrates the fall arrest cable 14 incorporated with pneumatic air powered device connection 26 that exits the exterior sheath of the fall arrest cable 14 at some point before the ring 34.
[019] FIG. 5 representatively illustrates a cross-sectional view of the interior of the fall arrest cable 14 having two parts enveloped by an exterior sheath 28. The accessory line 18 is positioned along-side the flexible cable 20 and both are wrapped together to make up one continuous cable for the substantial portion of the fall arrest cable 14.
[020] Generally, the fall arresting system 10 includes a retractable-cable reel 12, and a fall arrest cable 14 that is wound onto the retractable-cable reel 12. The retractable-cable reel 12 can be any retractable-cable reel suitable for use with a fall arresting cable, safety line, etc. For example, U.S. Published Application No.
2010/022448, which is incorporated herein in its entirety by reference, describes a retractable-cord reel that could be employed with embodiments of the present invention. The invention, however, is not limited to use with this specific retractable reel design, because one of ordinary skill in the art would readily appreciate that other retractable-cable reels could be employed without departing from the scope of the invention.

[021] The retractable-cable reel 12 includes a spool 16 mounted rotatably mounted on an axle 40 and a casing/housing 36 that encloses the spool 16. The fall arrest cable 14 wound on the spool 16 and extends through the cable outlet 42 away from the retractable-cable reel 12. The cable outlet 42 is located along the same axis as the spool's 16 motion, allowing the fall arrest cable 14 to proceed fluidly from the spool 16 to the attached individual located at the first end 30 of fall arrest cable 14.
[022] The fall arresting cable 14 is generally an elongated cable like structure that has opposing first and second ends 30 and 32. The fall arresting cable 14 includes a length of flexible cable 22 that has a tensile strength capable of arresting an individual's fall, such as, a steel cable, for example. A cable coupling, such as carabineer or ring 34 is attached to the first end 30 of cable 22 and removably attaches or secures the first end 30 of cable 22 to a user 22.
[023] The second end 32 of the fall arrest cable 14 attaches to the retractable-cable reel 12 at a point on the outside diameter portion 38 of the spool 16. The fall arrest cable 14 is wound on the spool 16, as shown in FIG 2, allowing the fall arrest cable 14 to continuously retract and extend from the retractable-cable reel 12 as the user 22 moves with the fall arresting system 10 attached. The accessory line 18 extends through the housing/casing 36 at the accessory line exit 48, located alongside the housing/casing 36, allowing the user 22 to connect the accessory line 18 to an electrical outlet or an air compressor.

[024] The fall arrest cable 14 further includes an accessory line 18 that extends substantially along the length of cable 22 between the first and second ends and 32. An exterior sheath 28 tightly envelopes both the flexible cable 20 and the accessory line 18 from the first end 30 to the second end 32. The accessory line 18 exits the sheath 28 before the ring 34 attached to the first end 30.
Depending on the model of fall arrest system 10, the accessory line 18 provides the user attached to the fall arrest system 10, with either the ability to power an electrical tool using the electrical device connection 24 or the ability to power a pneumatic air tool using the pneumatic air powered device connection 26, FIG. 3 and FIG.
4.
[025] Extending from the exterior of the housing/casing 36 is a casing attachment point 46. The casing attachment point 46 is the point where the reel hook 44 attaches to the retractable-cable reel 12. The reel hook 44 passes through the attachment hole 50 providing the user 22 with the ability to attach the retractable-cable reel 12 to a plurality of stationary points of safety. The stationary points of safety, preferably a building or like structure, is used to keep the retractable-cable reel 12 in a stationary position when the individual, attached to the first end 30 of the fall arrest cable 14, falls away from the retractable-cable reel 12.
