Description

FIELD

The invention, in various embodiments, relates generally to devices and methods for their manufacture and use in working on, for example, utility poles.

BACKGROUND

In the telecommunications or electronics industry, it is common practice for a technician (also referred to as a “linesman”) to scale a utility pole. The technician scales the utility pole to install equipment, to repair broken or damaged communications equipment, to test equipment, and/or for other work-related reasons. To safely and effectively scale a pole and perform line work, the technician must maintain and properly utilize various types of scaling and safety equipment. To utilize the various types of scaling and safety equipment, the technician must also have the skills and the physical ability to sustain a great strain on their legs and back while the technician climbs and/or maintains a position about the pole.

Conventional climbing equipment employed by a technician typically includes a pair of gaffs, a body belt, and/or a safety strap. In general, the gaff is a sharp blade protruding from the inside of the foot about mid-foot level and having straps that secure about the leg and/or feet of a technician. To climb, the technician drives one of the gaffs into the pole, steps up onto the gaff, and then drives the other gaff into the pole at a higher position. The technician continues taking steps up or “gaffs up” the pole until reaching a desired height.

The body belt is secured around the waist of the technician. The body belt includes pockets for carrying tools and rings (e.g., “D-rings”) for attaching the safety strap. The safety strap typically includes a hook (e.g., snap buckle) at each end and a buckle for adjusting its length. During climbing, both hooks of the safety strap are attached to the same ring of the body belt on the left hip. Once in a position to perform line work, the technician releases one end of the safety strap from the body belt. The technician then wraps the safety strap around the pole and reattaches the end of the safety strap to the body belt, thus allowing the technician to use his hands at the desired working elevation. Thus, the technician uses the safety strap for climbing as well as supporting the technician in his working position about the pole.

During elevated line work, both gaffs are pressed into the pole and the technician leans back against the safety strap. This position allows the weight of the technician to be supported by the gaffs and the tension in the safety strap.

DETAILED DESCRIPTION

It can be appreciated that commercial entities and other organizations that employ workers in elevated environments are aware of the potential risks attendant upon work performed in such environments. In view of this awareness, commercial entities and other organizations devote time and resources to promoting the safety of workers performing work in elevated environments to make the performance of work as safe as possible. Promoting safety of workers in elevated environments may involve instituting training programs and/or providing workers with a variety of support devices, support systems, backup devices and systems, and/or other means that promote the stability and safety of workers in elevated environments. Despite the best efforts of an organization to enhance the safety of its workers and reduce the risk of falling from elevated structures, for example, it is nonetheless difficult to eliminate all risks to workers performing work on such elevated structures.

Redundant systems for promoting safety of workers on elevated utility structures may thus sometimes be used. Such redundant systems can sometimes be beneficial in addition to the myriad of existing support systems, methods, devices and/or other apparatus employed by workers on elevated structures to reduce or mitigate risks associated with falling from utility structures, for example.

FIG. 1A illustrates one embodiment of a support device 10. As shown, the support device 10 may include a body portion 11 and a ring portion 12 extending from one end of the body portion 11. In general, the ring portion 12 may be structured and arranged to support various items including, but not limited to, equipment, hardware, and/or safety equipment used by a technician when performing elevated line work, for example. The ring portion 12 also may be used, for example, to clip the support device 10 to the belt of a technician. In some implementations, rope or wire may be passed through the ring portion 12.

The support device 10 also may include a first hanger portion 13 extending outwardly from the body portion 11. In one implementation, the first hanger portion 13 has a circular slot 14 for engaging a rounded shaft of a hook member (e.g., J hook). In some implementations, the support device 10 may be hung from a strand when the technician is on a ladder working on a stranded plant, for example. The support device 10 also may have a second hanger portion 15 that extends outwardly from the body portion 11 and includes a flat slot 16 for engaging a planar shaft of a hook member.

In this embodiment, the support device 10 also may include a hole 17 through the body portion 11 between the first hanger portion 13 and the second hanger portion 15. The hole 17 may be used, for example, to clip the support device 10 to the belt of a technician. In some implementations, rope or wire may be passed through the hole 17.

Referring to FIG. 1B, the support device 10 may be constructed so as to have a relatively thin and flat design. In general, this facilitates transport and use by a technician when performing elevated line work. In one embodiment, the first hanger portion 13 and the second hanger portion 15 extend outwardly from opposed sides of the support device 10 to achieve the relatively thin and flat design.

It can be appreciated that the choice of materials for construction of the support device 10 may be driven, at least in part, by the motivation to create an apparatus that is relatively lightweight, relatively compact and structurally sound and suitable for supporting items as intended during the use of such an apparatus. Materials for the support device 10 may include, where appropriate and suitable for the reasonably safe and functional practice of the various embodiments described herein, one or more of the following materials: metals such as steel, aluminum, for example, titanium and/or stainless steel or any other metal or alloy capable of withstanding stress and strain.

FIG. 2A illustrates another embodiment of the support device 10. As shown, the support device 10 again includes a ring portion 12 extending from one end of the body portion 11. The support device 10 also includes a first hanger portion 13 having a rounded slot 14 and a second hanger portion 15 having a flat slot 16. The first hanger portion 13 and the second hanger portion 15 extend outwardly from opposed sides of the support device 10 and are separated by a hole 17.

In this embodiment, the ring portion 12 includes an upper ring portion 12a and a lower ring portion 12b. The lower ring portion 12b may have a broad, gently curved inside surface to accommodate ropes and/or wires. In general, this makes the support device 10 useful in situations where a technician passes rope and/or wires through the ring portion 12 by reducing the likelihood of a snag. As shown in FIG. 2B, the lower ring portion 12b, in this embodiment, may be thicker than other portions of the support device 10.

FIG. 3A illustrates another embodiment of a support device. The support device 10 again includes a body portion 11 having a ring portion 12 extending therefrom. A first hanger portion 13 having a rounded slot 14 and a second hanger portion 15 having a flat slot 16 also extend from the body portion 11. The body portion 11 further includes a hole 17 positioned between the first hanger portion 13 and the second hanger portion 15.

As shown, the support device 10 may be provided with additional features for extending the usefulness of the device. For example, the support device 10 may include a flat-blade screwdriver head 18 on the body portion 11. In one embodiment, the flat-blade screwdriver head 18 may be positioned on the end of the body portion 11 opposite the ring portion 12.

The support device 10 also may include a plurality of dimples 19 and/or a plurality of bumps 20. In one implementation, the dimples 19 may be structured and arranged to short wire-wrap binding posts in central offices, and the bumps 20 may be structured and arranged to short screw-headed pairs. In one embodiment, the dimples 19 are provided on the first hanger portion 13 and the bumps 20 are provided on the second hanger portion 15. The positioning of the dimples 19 and bumps 20 may vary in alternate embodiments.

The support device 10 also may include a hex key tip 21 on the body portion 11. In one implementation, the hex key tip 21 may be used as a door key to open outside terminal boxes and/or SLC cabinets.

The support device 10 further may include a notch 22 and/or a flat edge 23 (e.g. 0.030 in flat). In one implementation, the notch 22 and/or the flat edge 23 may be structured and arranged to adjust spark plugs. In one embodiment, the notch 22 is provided on the first hanger portion 13 and the flat edge 23 is provided on the second hanger portion 15. The positioning of the notch 22 and/or the flat edge 23 may vary in alternate embodiments.

The support device 10 also may include a belt loop 24 so that the support device 10 may be used as a hand-line carrier. In one implementation, the belt loop 24 may be configured to fail if exposed to a predetermined tension (e.g. 20 lbs.). For the support device 10 to function as a hand-line carrier, wires may be fished through the ring portion 12, the hole 17, or draped over the hangers 13, 15 (which would be upside down). The support device 10 would be clipped to the belt of a technician using the belt loop 24. The belt loop 24 may be designed to fail (i.e. release) if tension exceeding a predetermined amount is experienced, for example, if the wire is caught during ascent.

Referring to FIG. 3B, the belt loop 24 may be constructed so as to have a relatively thin design. In general, the shape, width, and/or thickness of the belt loop 24 may be configured so that failure occurs at the desired tension.

As described above, in some implementations, the support device 10 may be hung from a strand when the technician is on a ladder working on a stranded plant, for example. In other implementations, the support device 10 may be hung from a hook member.
