The present disclosure relates to a fish rod hooks, and more particularly to specialized hooks for pulling and retrieving wires.
In the construction field, when remodeling of existing structures, electricians typically are required to install new wires or to retrofit existing wires through and behind the previously built walls, floors, and ceilings of buildings. The use of fiberglass poles, commonly called fish rods or fish sticks, to pull wires and cables through such inaccessible areas of a structure is widely known. A typical fish rod consists of long thin material, usually fiberglass, rigid enough to push through and past obstructions, let flexible enough to bend around some of these same obstacles. Fish rods are typically terminated with either a permanently installed engagement member, such as a hook or eyelet, or with a threaded member to which an engagement member or an additional length of fish rod may be affixed. Commonly engagement members in the prior art consist of standard J-shaped hooks, bullet noses, and wire cages, among others.
The common J-shaped hook is also convenient for hooking onto and retrieving objects which may be inaccessible behind the walls of a structure, but generally has the weakness that it are likely to snag upon retrieval because the open portion of the hook protrudes outward from the axis of the fish rod. Because the J-hook is open on one side, it is also highly likely that a pulled wire will slip out of the grasp of the J-hook if it encounters an obstacle. It would therefore be advantageous to retain the wire-retrieving benefits of the J-hook while eliminating the tendency of the J-hook to snag on corners and other surfaces and to drop wires.
Another common engagement member for fish rods is commonly referred to as a “bullet nose.” A bullet nose engagement member is a rounded, low-profile termination of a fish rod, usually not much larger in diameter than the fish rod itself, with a hole in the nose to allow for wires and cables to be tied to the bullet nose, either directly or through the use of wire mesh grips common in the prior art. The bullet nose tends to be easy to feed into a work area and retrieve from, but lacks the ability to grab or retrieve any objects that may have been dropped in the work area. It would therefore be advantageous to retain the rounded low profile of the bullet nose for ease of insertion and recovery and still allow for objects to be retrieved.
A third common engagement member for a fish tape is a “wire cage.” A wire cage engagement member is a high profile ball-shaped cage of rigid metal attached to the end of a fish rod. As with the bullet nose engagement member, wires and cables may be tied to a wire cage and pulled through the work area. The large, rounded profile of the wire cage is helpful for pushing aside any existing wires or other obstacles, clearing the way for the pulled wires, but the wire cage is not able to pick up or retrieve any wires in the work area and is too bulky to use in many crowded areas. It would therefore be advantageous to retain the area-clearing benefits of the wire cage while and still allow for the retrieval and maneuvering of items at the end of the fish tape.
The present invention solves all of these problems and allows a user to perform all of the tasks normally performed by the bullet nose, the J-hook, and the wire cage with one simple device.
In an example embodiment of the present invention, an improved wire pulling hook is disclosed. The improved wire hook for use with fish rods overcomes the above-mentioned limitations of the fish rod hooks now present in the prior art. The purpose of the present invention is to provide all of the advantages of the prior art hooks, including retrieval of dropped or inaccessible wires, low-profile pulling of wires, and clearance of obstacles, while reducing the tendency of such systems to drop wires or snag on protruding surfaces.
To accomplish this purpose, this example embodiment of the present invention consists of a pair of S-shaped hooks in lieu of the single J-hook, wire cage, or bullet nose, the S-shaped hooks attached to a post in an opposite and nearly parallel configuration. The lower portion of each of the hooks presents a profile similar to that of a J-hook attachment member to a wire to be retrieved and the upper portion of the hooks presents a profile similar to that of a wire cage to clear obstacles.
Retrieval of wires is accomplished by positioning each of the two S-shaped hooks on either side of a wire to be retrieved, such that the wire is located between the two hooks. By twisting the rod in a particular direction, the S-shaped hooks are rotated to entrap the wire within both of the two hooks. When in this locked configuration, the wire cannot fall out of the hooks because each opposed hook member effectively closes the gap of the opposing hook. The hook is unlikely to snag because the upper portions of the hooks shield the open lower portions of the hooks and clear obstacles away from a potential snag.
This summary is expository only and is not intended to be in any way limiting of the invention. In addition to the illustrative aspects, features, and properties of the embodiment above, additional aspects, features, and properties will become apparent by reference to the drawings and the following detailed description.
In this description, references are made to the drawings which are part of the description. In the drawings, similar symbols identify similar parts, unless noted otherwise. The embodiment described in the detailed description, drawings, and claims is not intended to be limiting. Other embodiments may be used, and other changes may be made within the scope of the subject matter of this description. It will be apparent that the aspects of this disclosure can be arranged, substituted, combined, separated, and designed in multiple configurations, all of which are contemplated in this description.
In structures which have multiple stories, wires and cables are commonly installed vertically across multiple floors. The method commonly used is “fishing,” employing a long thin “fish rod” of fiberglass or other material to enter the wall at a desired location, pushing it through an opening in the floor or ceiling, and retrieving the rod on the other side. The present application is directed to a method and system for terminating such a fish rod to allow it to be used to pull, retrieve, and route wires in an installation or other similar application.
