DETAILED DESCRIPTION

[0021] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0022] As noted above, there is a need in the art for a cable or wire installation tool that enables a user to more easily and precisely install wire or cable across an attic, drop ceiling, crawl space or another similar limited access area. Additionally, there is a long felt need in the art for a jet, lead or fishing line projectile mechanism that eliminates the need for the installer to enter a narrow space to pull line or cable from one end to the other, and that reduces the potential for injury to the installer. Moreover, there is a long felt need in the art for a line slinging or positioning tool that eliminates the need for the installer to buy expensive rods, drones or robots for jet, lead or fishing line distribution, and that reduces the time necessary to complete the installation process. Finally, there is a long felt need in the art for a jet, lead or fishing line distribution tool that is relatively inexpensive to manufacture and that is both safe and easy to use.

[0023] The present invention, in one exemplary embodiment, is a novel cable and wire installation tool that enables an installer to fire a jet or other lead line across a drop ceiling, attic, crawl space or other confined or constricted space. The installation tool is comprised of a slingshot having an elastic or tensionable element to be pulled and released by a user to project a dart like device that is attached to a length of jet line. The installation tool further comprises a laser sight to enable the user to select a target and establish a path that the jet line is to travel, and a handle for the user to hold, grasp and control the tool. In use, the user pulls back on the slingshot with the dart positioned therein and releases the slingshot from the pulled position towards the target, thereby releasing the energy of the elastic or tension element to propel the dart with the jet line attached thereto towards the target. The jet line can be of a fluorescent or neon color such that it can be seen easily in the dark or a dimly lit area.

[0024] Referring initially to the drawings, FIG. 1 illustrates a perspective view of one potential embodiment of the cable and wire installation tool 100 of the present invention in accordance with the disclosed architecture. As shown, the installation tool 100 is a portable and relatively lightweight tool for throwing jet, lead or fishing line 108 across a drop ceiling, attic, crawl space or other hard to reach area. The installation tool is comprised of a slingshot 104 attached to a top of a handle 110 of the tool 100. The handle 110 may also include finger grip areas 103 and a gripping surface 107 to aid in holding the tool 100. The frame of the tool 100 may further comprise a gauge 109 to show the resistance on the slingshot 104 as it is being pulled back for use by a user. The slingshot 104 is similar to a conventional slingshot and is comprised of a rubber, elastic or other tensionable element 1044 attached to the handle at end points 1040, 1042. If rubber tubing is used, the ends of the rubber tubing may be inserted on the end points 1040, 1042.

[0025] The installation tool 100 further comprises a canister mechanism 102 that is attached to the handle 110, wherein the canister 102 is generally cylindrical and has an opening therein for storing the jet line 108 until it is propelled forward from the installation tool 100. More specifically, the canister 102 has a recoil mechanism that has a length of jet or other line 108 rolled thereon. To shoot the jet line 108, a user holds the handle 110 of the installation tool 100 in his or her passive hand, and uses their dominant hand to pull backwards on the rubber or elastic element 1044 to provide sufficient force to propel the dart structure 120 and the jet line 108 attached thereto towards the target.

[0026] Additionally, a laser light emitter 106 is positioned along the bottom surface of the canister 102 to help the user locate an approximate target location and establish a flight path for the line 108 to travel. Once the path is established, the elastic or rubber element 1044 of the slingshot 104 is pulled backward to launch the jet or fishing line 108 from the canister 102 towards the target. The laser light 106 helps in improving the accuracy of the launch of the jet line 108. In addition, a level or angle alignment guide 105 aids in maintaining the desired target line and in holding the device along a fixed path.

[0027] The installation tool 100 of the present invention can be used to pass lightweight conductor and communication cables and wires through otherwise inaccessible spaces and without the manual labor and time-consuming nature of existing installation processes. In one embodiment, a canister cap (not shown) may be included to cover the opening 1020 of the canister 102 when the canister 102 is not in use. A jet or other line 108 spool is placed in the recoil mechanism of the canister 102 and is used to assist in the launch of the jet line 108. At one end of the jet line 108, a dart or lead structure 120 is present to give stability to the motion of the jet or lead line 108 during its flight path. The dart structure 120 should be used for flight stabilization for each flight before launching the jet line 108 using the slingshot 104.

[0028] The dart structure 120 may be removably attached to the jet or fishing line 108 and a hook is present at the end of the dart structure 120 to which the jet line or fishing line 108 is tied. It should be appreciated that the dart structure 120 may be of different dimensions and/or weights depending on the particular application. One criteria for the selection of the dart or other weighted element 120 can be the desired distance of the target from the user. The dart structure 120 can be comprised of a lightweight plastic, metal or other durable material depending on the needs and/or preferences of the user, but should be heavy enough to pull the jet line 108 when launched from the slingshot 104, and light enough so that it is capable of travelling the desired distance.

[0029] FIG. 2 illustrates a perspective view of one potential embodiment of the cable and wire installation tool 100 of the present invention in accordance with the disclosed architecture, wherein the tool 100 is being utilized by a user to launch a projectile 120 attached to a distal end of a length of jet line 108 towards a target. More specifically, to use the installation tool 100, a user 200 holds the handle 110 of the tool 100 with a first hand 202 and pulls back on the rubber or elastic member 1044 of the slingshot 104 with a second hand 203, wherein the dart 120 with a distal end of the jet line 108 attached thereto is positioned in the slingshot 104. The user 200 then aims the installation tool 100 is the general direction of the intended target, and uses the laser light 106 to better hone in on the target, wherein the laser light both provides better visibility of the target and helps in maintaining the path of the projectile towards the target. When the user 200 releases the slingshot rubber 1044, the jet line 108 from the canister 102 is released towards the target at a relatively high speed but in a stabilized manner. As best shown in FIG. 2, the jet line 108 from the canister 102 can be shot across an attic 210, a drop ceiling, through a crawl space, etc.

[0030] In a preferred embodiment of the present invention, the resistance of the slingshot band is about 5 pounds (2.3 kg) at the point of elongation. If the band is then further stretched up to 200% elongation, the resistance would be about 8 pounds. There is approximately a 20-30% increase in the amount of resistance, and the resistance preferably ranges from about 1 pound to about 18 pounds with about 5 to 14 pounds of resistance being preferred. Pulling back on the rubber or elastic bands causes the draw force “F” to increase as the draw distance “d” increases, similarly to when a spring is stretched. The maximum draw force (F.) of the person operating the slingshot portion of the installation tool 100 should be at the point at which his/her draw length is a maximum (d.sub.max). This results in the maximum amount of energy stored in the rubber or elastic bands (provided by the slingshot operator), and therefore results in the most powerful shot. To achieve this ideal situation, a rubber band made of appropriately selected material would have to be used which matches the strength limits of the slingshot operator.

[0031] The energy stored in the rubber bands and delivered to the projectile (assuming zero energy loss), is given by the area under the curve, which is given by E=(½)d.sub.maxF.sub.max, where E is the stored energy. Assuming zero energy loss, this energy is equal to the kinetic energy of the projectile upon release, which is given by E=(½)MV.sup.2, where M is the mass of the projectile and V is the speed of the projectile upon release. Equating stored energy with kinetic energy we have the equation d.sub.maxF.sub.max=MV.sup.2.

[0032] The elastic or rubber bands 1044 may be tubing or flat bands depending on the preference of the user, or the particular application. However, tubing is preferred as it tends to last longer, and provides for relatively easy replacement when needed. The frame of the installation tool 100 is preferably manufactured from a fiberglass, plastic, metal, metal alloy, glass filled nylon or a combination thereof, and the elastic or rubber bands 1044 are preferably made from a vulcanized rubber.

[0033] FIG. 3 illustrates a perspective view of one potential embodiment of the cable and wire installation tool 100 of the present invention in accordance with the disclosed architecture, wherein the tool 100 has been used by the user 200 to launch the projectile 120 attached to a distal end of a length of jet line 108 towards a target. More specifically, when the sling shot 104 is released from the pulled back position by the user 200 while holding the tool 100 in the first hand 202, the jet line 108 along with the dart or lead structure 120 is released from the canister 102 and the recoil mechanism and projected towards the target selected by the user 200 using the laser light 106 and/or the level or angle alignment indicator 105. In the present embodiment, the jet line 108 is sent across a drop ceiling 300. In the canister 102, a spool of line of up to 1200 feet in length can be placed which can be thrown towards the target using the sling shot 104. It should be appreciated that no electronic component is required for the installation tool 100 of the present invention to function. Additionally, the 110 handle may also include a handle rest 112 for supporting the arm of the user 200 (as best shown in FIG. 2) and a recoil shield or guard 115 to prevent the elastic bands from hitting the operator 200 of the tool 100.

[0034] The laser sight 106 may use a battery 111, such as 3-LR44 type batteries, for providing the laser functionality. In one embodiment, there can be a control button 113 (see e.g., FIG. 2) to increase or decrease the velocity of the launch of the jet line 108 (e.g., by controlling the amount of drag on the line 108 via the recoil mechanism) to fit various requirements of a user. For example, for smaller distances, the velocity of the launch of the jet line 108 can be reduced, and for longer distances, the velocity of the launch can be increased using the control button. Based on the velocity, the distance of the projectile will be decreased or increased. Additionally, it should be noted that any mechanism other than the recoil mechanism which allows the jet or fishing line 108 to be launched upon releasing of the pulled back slingshot 104 can be used within the canister 102 of the installation tool 100 as long as the objective of accurately sending the jet or fishing line 108 to the target is achieved.
