1. Technical Field
This invention relates to a device for transporting a spool of cable and, more particularly, a portable device that is removably connectable to a spool of cable.
2. Prior Art
Various tools have been devised for insertion internally of a hollow element, such as a spool of cable, to grasp and lift that element. Such objects are large and heavy, which makes them very awkward to handle. Wire used in manufacturing operations, such for example as making small coiled springs, is fabricated and shipped in large coils typically weighing 1,000 pounds each. The coils are typically wound with open cores, which may include a paperboard sleeve.
Handling such coils, which are known in the trade as “reel-less cores”, is difficult. Devices for handling coils are not entirely new but their impracticality is born out by the fact that none of them is in general usage in industry today. Of the most practical ones, it may be said that they are unduly complicated and necessitated considerable time and mechanism to effect the gripping or releasing of the coil. In addition to such shortcomings, previous devices often damage the coil, thereby necessitating a repairing operation or the scrapping of the coil in whole or in part. Other prior art spool carriers designed heretofore have handles that are too small and cause finger strain due to repetitive gripping.
Accordingly, a need remains for a portable device that is removably connectable for transporting a spool of cable and, which overcomes the above-noted shortcomings.
In view of the foregoing background, it is therefore an object of the present invention to provide a portable device for transporting a spool of cable. These and other objects, features, and advantages of the invention are provided by a device including a stationary handle having a central portion positionable within a hand of a user and a movable handle disposed below the stationary handle that is selectively movable along a substantially vertical path between raised and lowered positions. The movable handle cooperates with the stationary handle during operating conditions. The stationary handle may have a plurality of substantially vertical grooves formed therein for guiding the movable handle therealong.
The present invention further includes a housing positionable into a spool opening and is secured to the stationary handle. The housing includes a plurality of pistons slidably mounted therein and has a plurality of spaced apertures formed about the plurality of pistons. The housing further includes an elongated fastening member secured to the plurality of pistons and to the movable handle. The fastening member may be threadably engaged with the plurality of pistons and may be disposed substantially medially thereof. The housing may further include an upper section and a lower section integral therewith. The upper and lower sections may each have a predetermined diameter.
Advantageously, a plurality of latching members are pivotally connected to the plurality of pistons respectively and are movable between retracted and extended positions through the plurality of apertures as the movable handle is lowered and raised respectively. A first set of the plurality of latching members may be diametrically spaced approximately 120 degrees apart. Similarly, a second set of the plurality of latching members may be diametrically spaced approximately 120 degrees apart. The second set of latching members may be disposed below the first set of latching members for cooperating therewith to maintain the device securely engaged with a spool of cable. The plurality of pistons engage a select portion within a spool opening and thereby allow an operator to lift a spool and transport same while the movable handle is maintained at a raised position. The plurality of latching members are disengageable from a spool when the movable handle is released to a lowered position.
The novel features believed to be characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings in which:
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a preferred embodiment of the invention is shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein. Rather, this embodiment is provided so that this application will be thorough and complete, and will fully convey the true scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the figures.

Similarly, a second set of the plurality of latching members 51 are diametrically spaced approximately 120 degrees apart. The second set of latching members 51 are disposed below the first set of latching members 50 for cooperating therewith to maintain the device 10 securely engaged with a spool of cable. The plurality of pistons 41 engage a select portion within a spool opening and thereby allow an operator to lift a spool and transport same while the movable handle 30 is maintained at a raised position. The plurality of latching members 50, 51 are disengageable from a spool when the movable handle 30 is released to a lowered position.
Contractors and electricians might find using this invention to be an essential part of their workday. In addition to being easy to operate, the present invention may be designed to be compact. This feature allows it to be conveniently stored in a pouch or holster attached to a work belt. To have such a necessary tool within reach is ideal for the work site.
While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the present invention may include variations in size, materials, shape, form, function and manner of operation. The assembly and use of the present invention are deemed readily apparent and obvious to one skilled in the art.
