The present invention relates generally to tools for installing cables and other such devices within buildings, and more particularly to an illuminated cable pulling device.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
A task often encountered by electrical contractors, telephone workers and cable television installers, is to run physical cables from one location to another within a building structure. Whether it is an office building with suspended ceilings, or a home with fixed ceilings, the process typically requires two workers, wherein the first worker would cut an opening in the ceiling, and thread the cable through the opening and upwards into the attic space. Once positioned within the attic, the second worker must then attempt to locate the end of the cable through verbal guidance from the first worker. However, it is not uncommon for the cable to become buried in attic insulation and other such items, making the process of locating and retrieving it a difficult and time consuming endeavor.
Moreover, even when the cable is able to be positioned through the ceiling and insulation, it is extremely common for one of the workers to temporarily lose their grip on the cable itself, resulting in the cable falling back out of the ceiling and onto the floor, wherein the entire process must be started again.
Accordingly, there remains a need for a device capable of allowing a single user to quickly and easily position a cable or other such device within an attic space and to identify and retrieve the same in a manner that does not suffer from the drawbacks of the above noted process.
The present invention is directed to a cable pulling and retrieval device. One embodiment of the present invention can include an elongated generally hollow and transparent wand that is interposed between a handle and a hole saw. The handle can include a generally hollow portion for receiving and storing one or more batteries, and can further include a light producing device that can generate a focused beam of light and to direct the same into the wand.
In another embodiment, the hole saw can include a plurality of saw tooth ridges that can cut through a material such as drywall, and the handle can include a cable attachment unit which can be removably secured to a cable. Additionally, the device can further include one or more generally resilient arms which can transition between an extended and retracted state.

As described herein, the term “removably secured,” and derivatives thereof shall be used to describe a situation wherein two or more objects are joined together in a non-permanent manner so as to allow the same objects to be repeatedly joined and separated.
As described herein, the light producing device 25 can include any number of different components which alone, or in combination function to generate light in any number of different colors, spectrums and intensities. For example, the light producing device can include one or more LED or incandescent light bulbs and a reflector, for example, which can function to generate a focused beam of light. Light producing devices and their associated components are well known in the art and include U.S. Pat. No. 4,819,141, the contents of which are incorporated herein by reference.
Although illustrated above as being fully contained within the handle portion 20, other embodiments of light producing devices are contemplated, wherein a portion of the same are positionable within the transparent wand. For example, in another embodiment (not illustrated) the light producing device can further include an elongated strand of LED lights that are disposed along the length of the wand 30.
In one embodiment, the handle 20 can further include a cable attachment unit 29 that extends from the base end 22 of the handle 20. In one embodiment, the cable attachment unit 29 can be constructed from an elongated, generally malleable wire having a hook, loop or other such connector 29a at a distal end. In operation, the connector 29a can be removably secured to a wire/cable that is being installed by the device.
Although described above as including a particular construction material and attachment location onto the handle, this is for illustrative purposes only, as the cable attachment unit 29 can include any number of different shapes, sizes, construction materials and connectors which can function to mate with a cable or wire in a nonpermanent manner.
In one embodiment, a plurality of apertures 32 can be disposed along the main body 31 at a location that is adjacent to the saw attachment end 31c. Each of these apertures can function to deflect a portion of the supplied light away from the device, in order to increase the visibility of the device when the same is used within an attic or other dark location.
In another embodiment, the wand can also include a plurality of generally resilient arms which can extend diagonally from the main body 31. As shown, each of the arms can include a first end 35a that is in communication with the middle portion 31b of the main body, and a second end 35b which can bend or otherwise flex inward (see arrows a) when a force is applied thereon. In this regard, when the arms are in a diagonal position they are in an extended state, and when the arms are flush with the side of the main body 31, they are in a retracted state.
As described herein, each of the arms can be constructed from any number of resilient materials such as plastic and/or lightweight resilient metal wires such as steel and aluminum, for example, and can be secured onto the main body in accordance with known manufacturing techniques. In another embodiment, (See
In one preferred embodiment, the hole saw 40 can be constructed from hardened steel, however, any number of other sturdy materials such as aluminum, plastic and PVC, for example, that are capable of cutting through drywall, insulation, and other such building materials, are also contemplated.
As described herein, the wand 30 can be secured to one or both of the handle 20 and the saw 30 in a removable manner, so as to allow a user to utilize any number of different sized hole saws 40 with the same wand 30 and handle 40; or to utilize any number of different handles 20 with the same wand 30 and hole saw 40. In the preferred embodiment, a plurality of embedded elements 11a can be located along the wand attachment end 21c of the handle 20, and a plurality of complementary threads 11b can be secured along the handle attachment end 31a of the wand 30 Likewise, a plurality of embedded elements 12a can be located along the saw attachment end 31c of the wand 30, and a plurality of complementary threads 12b can be secured along the wand attachment end 41a of the saw 40. Threaded elements having lands and grooves for securing complementary objects together via a twisting motion are extremely well known. Accordingly, no further description will be provided.
Although described above as utilizing threaded elements 30a-30b, and 31a-31b, capable of creating a secure attachment point between two objects when a rotational force is applied thereto, this is for illustrative purposes only, as any number of known connectors and components capable of creating a removable seal between two items can also be utilized. Moreover, alternate embodiments of the device are also contemplated wherein the wand 30 can be secured to each of the handle 20 and the saw 40 in a permanent manner, and in accordance with known construction methodologies which may utilize materials such as glue, resin, and/or hardware such as screws and bolts, for example.

As such, those of skill in the art will recognize that the device can include any number of different dimensions suitable for cutting openings of any desirable amount (e.g., 1″, 1.5″, 1.75″, 2″, 5″, 10″, etc.,).
Once the opening has been created, the saw 40 and wand 30 can be inserted through the opening 6 (see arrow c), and the flexible arms 35 can bend/retract inward towards the main body (see arrow a) until the bottom end of the arms have passed through the opening. Once the arms have passed through the opening 6, the arms can extend outward, wherein the bottom ends 35b can make contact with the upper surface of the material 5 in order to prevent the device from passing back through the opening.
Next, the user can attach a cable 1 or other such device onto the attachment unit 29, and can activate the light producing device 25. Once activated, the light producing device 25 can illuminate the wand 30 in order to allow the user to quickly and easily identify the location of the device from the attic. At that time, a user can retrieve the device 10 and the cable 1 to which the device is attached.
Although illustrated as protruding from the bottom of the handle, other embodiments are also contemplated wherein the bottom of the handle itself forms the drill protrusion.
As described herein, one or more elements of the illuminated cable pulling and retrieval device 10 can be secured together utilizing any number of known attachment means such as, for example, screws, glue, compression fittings and welds, among others. Moreover, although the above embodiments have been described as including separate individual elements, the inventive concepts disclosed herein are not so limiting. To this end, one of skill in the art will recognize that one or more individual elements may be formed together as one continuous element, either through manufacturing processes, such as welding, casting, or molding, or through the use of a singular piece of material milled or machined with the aforementioned components forming identifiable sections thereof.
