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

U.S. application Ser. No. 10/643,177 filed Aug. 18, 2003 entitled “Support Device,” which is incorporated herein by reference, discloses a support device that is manufactured, in one embodiment, by adding support members to a shank or casting an entire device in the desired shape. Various embodiments of the present invention permit ordinary steel or alloyed rod stock to be used in creating the support device, thereby potentially reducing manufacturing costs while producing an effective support device.
The support members 2 and 6 described above may be formed, in one embodiment, by splitting the second end 18 of the shank 12 by any means suitable for splitting a metal or alloy. These may include, for example, punching a section 22 out of the end 18, as depicted in
After forming the support members 2 and 6, it may be necessary to apply metallurgical techniques to the support device 10 to achieve the desired strength and rigidity. In one example, the fully formed support device 10 may be stress-relief annealed to improve its metallurgical qualities.
Materials for the shank disclosed herein 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. It can be appreciated that the choice of materials for construction of the various structural elements disclosed herein 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 use of such an apparatus.
The driving device 100 may be constructed of any durable material such as, for example, metals such as steel, aluminum, titanium and/or stainless steel or any other metal or alloy capable of withstanding the stress and strain as described herein. The driving device 100 may be, in various embodiments, attached to the support device 10 using, for example, any type of adhesive or weld.
