DETAILED DESCRIPTION OF THE INVENTION
(23) To promote an understanding of the principles of the present invention, descriptions of specific embodiments of the invention follow and specific language is used to describe the specific embodiments. It will nevertheless be understood that no limitation of the scope of the invention is intended by the use of specific language. Alterations, further modifications, and such further applications of the principles of the present invention discussed are contemplated as would normally occur to one ordinarily skilled in the art to which the invention pertains.
(24) FIGS. 1-13 illustrate various views of exemplary embodiments of the present invention. Illustrated are a pointed portion and tail portion and an additional pointed portion with one or more holes or slots wherein wire may be inserted, or attached, such that it may be pulled through a conduit.
(25) FIGS. 14 A-K illustrate various views of an exemplary embodiment of the present invention. In this embodiment, an overall length OL is a distance from tip to tip of leader 10 (1.538 inches in this embodiment). Overall length OL may be broken down into subparts front length FL, mid length ML, and end length EL (i.e., OL=FL+ML+EL). Overall length OL may vary from 0.5 inches to 3 inches (the maximum length is limited in some part by the inner diameter of the conduit being snaked). Front length FL may vary from 0.1 inches to 1.5 inches. Mid length ML may vary from 0.0 inches to one inch and in some embodiments from 0.2 inches to 0.4 inches. End length EL may vary form 0.1 inches to 1 inch and in some embodiments from 0.25 inches to 0.6 inches. Angle may vary from 10 to 50 and in some embodiments from 15 to 40, and in other embodiments from 18 to 30. Angle may vary from 10 to 50 and in some embodiments from 15 to 40. Angle may vary from 0 to 45 and in some embodiments from 15 to 35. Angle may vary from 0 to 90 and in some embodiments from 20 to 90, and in other embodiments from 50 to 70. The end of the tail portion (i.e., at the end where the fish tape is exposed and inserted into the leader, the leader may have a sharp edge, may be angled such as by angle (and/or ), may be rounded or filleted, or otherwise shaped so as to more freely travel through the conduit without getting caught up. Further, at the pointed end (i.e., a the end of the leader opposite the tail, the tip may be pointed as shown in various figures, may be rounded, blunted, clipped, or otherwise angled (i.e., in some embodiments, there may be no sharp edges on the pointed portion and/or the tail portion of the leader, whereas other embodiments may have one or more sharp edges). Angle is the angle of motion by which the fish tape may be pivoted with respect to the leader. In some embodiments, the fish tape has a generally rectangular cross-sectional shape. In some embodiments, the slot of the leader through which the tape is inserted is round. As one axis of the tape has a relatively thin profile, and if the slot in the leader is round, there will be a greater movement permitted for the thinner profile of the tape in a given direction, whereas the motion in the orthogonal plane is much restricted relatively. Further, in some embodiments, the slot in the leader is larger than the tape such that the leader is able to pivot about the tape such that as the leader travels through a conduit, it may pivot even if the tape is not.
(26) The cavity internal to the leader (cavity on FIG. 14 D) has at least one portion large enough to receive a folded over piece of the fish tape, larger/wider cavity portion 60 and the at least one smaller/narrower channel portion 62 (i.e., the channel between the cavity and the outside through which the tape is routed) is sufficiently narrow to not allow the folded over portion of the tape to be inadvertently pulled through, but still wide enough to permit the tape to pivot with respect to the leader and vice versa.
(27) In various embodiments, wider cavity portion 60 has straight walls. In the embodiment of FIG. 14 D, the cavity walls at the wider portion are not only straight, they are parallel such that the shape of the cavity is cylindrical in wider portion 60. In various embodiments, narrower cavity portion 62 has straight walls. In the embodiment of FIG. 14 D, the cavity walls at the narrower portion are not only straight, they are parallel such that the shape of the cavity is cylindrical in narrower portion 62.
(28) In this embodiment, there is a transition 64 between wider portion 60 and narrower portion 62. Thus, several embodiments, including the one illustrated in FIG. 14 D have a stepped recess allowing for the tape.
(29) FIGS. 15A-J illustrate various views of another exemplary embodiment of the present invention.
(30) The various components and members of the present invention may be comprised wholly or in part of any suitable materials including, but not limited to, steel, aluminum, ceramic, wood, alloys, plastic, rubber, carbon fiber, fiberglass, and stainless steel.
(31) While the specification has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these embodiments. Also note that the housing and other components may be of any suitable shape depending on the desired application for the device. Accordingly, the scope of the present invention should be assessed as that of the appended claims and any equivalents thereto.
