Nelson E. Phero 43 Beebetown Road Hammontown, NJ 08037 SKID WRAP ROLLER
FIELD OF THE INVENTION
The present invention is relative to an invention which facilitates the process of wrapping skids in such a manner so as to secure their contents without causing potential injury or harm to the laborer.
BACKGROUND OF THE INVENTION
The packing industry is renowned for the back injuries and muscle strains that often afflict its laborers and packers. Improvements geared toward the ergonomics of motion are often overlooked where manual laborers are concerned. The current invention is related to the field of skid wrapping which is integral to t:he freight or packing and shipping industries.
None of the relevant art, consisting of plastic wrap devices for wrapping "skids", have resolved the need for the operator to wrap skids from au awkward, bent over position, that ~~cncrally puts strain on the spinal alignment and other muscles. furthermore, smaller loads, which arc too low to manipulate, also pose safety risks for the designated wrappers; although this type of load is generally placed on a forklift or electric lift to increase accessibility, the skid wrappers must often pass their arms and sometimes head beneath the skid in order to completely w°rap the goods.
U.S. Patent 4,102,513 issued to Twyman Guard on September 14, 1997 describes a hand-held apparatus which is used to wrap plastic stretch film around an object. Unlike the present invention, Guard's device has a short handle which still requires the laborer to enter into awkward and possibly dangerous situations in order to surround the object with this fillll material.
U.S. Patent 4,535,951 issued to Paul K. Riemenschneider, III on August 20, 1985 describes an object useful in wrapping objects with a stretch film as well. This device, however, involves a mechanism in which a film roll with a tubular rigid core is clamped in between a pair of opposed core holders. A tension control assembly between the core and the core holders is responsible for adjustment of tension in the wrap during the wrapping process. Unlike the present invention, Riemenschrleider's device does not provide an easier method to wrap the object which is beneficial to the health and safety of the laborer. Due to the design of the present invention, a user may wrap well above and below regular reach eliminating undue tension from bending aIld standing on toes to reach low and high objects respectively.

- 2 -Nelson E. Phero 43 Beebetown Road Hammontown, NJ 08037 SUMMARY OF THE INVENTION
The present invention is a device that is safer and more convenient for the operator to use than conventional wrapping methods. More specifically, the present invention is a skid wrap roller device which enables the operator to wrap skids from a safe position minimizing the risk of strain or other injury to life and limb. The present invention includes a pole, with a stop on one side, inserted into the hollow center of a spool of plastic wrap. The present invention provides the user greater control of the wrapping process while operating the device from a standing position.
The general structure of the present invention is a 60" wooden or hollow metal pole ('/2"
dia.) with a 6" diameter plastic base and rubber stopper at one end. A
standard-sized plastic wrap spool can be slid onto the pole from the other (unstoppered) end. The extended pole functions in like manner to a broom handle, enabling the operator to grasp the tool and manipulate the direction of the wrap from the top end (analogous to the broom handle), while the plastic wrap unrolls from the spool at the bottom end (where the broom head would be), ultimately reaching the desired goal of completely encasing the skid.
The wrap circumvents all elements which are placed upon the skid in an organized and uncompromising fashion to the laborer's well-being. The skid wrapper will be at less risk for potential back and neck pain as well as spinal misalignment.

DETAILED DESCRIP'CION OF THE PREFERRED EMBODIMENT
The present invention has a long wooden or metal pole (10), as shown Figure 1, which is approximately 60" long; a foam grip (70) is disposed at the end of the pole ( 10). The long length of the pole (10) allows the laborer to hold the device and extend a spool (80) of wrap over an area to be covered without the laborer bending down and twisting the laborer's body in an awkward position. The length of the: present invention eliminates squatting or climbing to properly wrap beds of items, and eliminates conventional ladder use in most wrapping due to height, because the spool (80) is disposed far along pole (10).
The pole ( 10) is inserted into spool (80) of wrapping material. Spool (80) is hollow. The diameter of 1 inch in the pole (10) provides for versatile use regarding different size spools (80) of wrapping material. Sleeve (68) is mounted atop pole (10) and has holes (50) along the

- 4 -Nelson E. Phero 43 Beebetown Road Hammontown, NJ 08037 diameter to act as attachments for a conventional cotter pin (not shown). The holes (50) are positioned along sleeve (68) for a 20~", 18", 15", or I 2" spool (80) of wrap, and corresponding holes (not shown) are similarly positioned along pole (10). It is contemplated that variously positioned holes (50) can be positioned along sleeve (68), and corresponding holes (not shown) can be similarly positioned along pole (10) depending on the length of a particular spool (80) chosen to be employed with the present invention. 'fhe hollow pole (10) serves as an axis about which the spool of wrap (80) can rotate. The smooth surface of the pole ( 10) allows for accelerated turning of the spool, and easier, expedited completion of the wrapping.
A stopper (40), preferably m;~de of rubber, is continuous with a first end of the pole (10).
The use of rubber for the stopper (4C1) allows easy turning access if the first end is placed on warehouse floors, loading docks or truck trailer beds while wrapping. The stopper (40) also protects low ceilings from marring as would happen with an unprotected end.
The stopper (40) also acts as a safety measure to word;ers around the user if the present invention is extended in a somewhat horizontal manner from the objects being wrapped (not shown). Risk for injury is minimized by use of the stopper (40) if collision with other laborers should occur.
Tension from a circular plate; (30) on the bottom side of the spool (80) and circular plug (20) on the top side of the spool (80) of wrap allow for secure and taut wrapping of the objects being wrapped (not shown). The circular plate (30) acts as a seat for an end of the spool (80) of wrap. The circular plug (20) also acia as a friction point to assist in the unraveling of the spool (80) of wrap. The plug (20) and plate (30) secure the spool (80) of wrap on the pole (10). The

- 5 -Nelson E. Phero 43 Beebetown Road Hammontown, NJ 08037 circular plug (20) is easily removed for spool (80) replenishment. 'The plate (30) and plug (20) are preferably fabricated of heavy plastic that is durable and easy to clean if necessary. In the preferred embodiment of the presenl: invention, there are no bolts or screws necessary for attachment of plug (20) or plate (30). Plug (20) and plate (30) are separated from spool (80) via plug ring (22) and plate ring (32), respectively, which function like conventional washers.
Between plate (30) and stopper (40) are threads (34) which are part of pole (10). Threads (34) serve as a mounting point for tensioner (33), which is threaded on threads (34). Depending on the amount of resistance desired ;as the laborer turns spool (80), the tensioner (33) can be turned on threads (34) to apply pressure to plate (30) and cause spool (80) to turn more slowly, or tensioner (33) can be turned on threads (34) to remove pressure fram plate (30) and cause spool (80) to turn more quickly.
Also included in the present invention is a brake assay (58) shown in Figure 2 as an exploded view. The brake assay (58) works much like a bicycle brake, in that it has an arm (60) that can be depressed to stop the flow of the spool (80) of wrap around an object (not shown) being wrapped. The laborer completes the final wrapping motion around the object being wrapped and depresses the arm (60) so that it frictionally engages spool (80) to prevent spool (80) from moving. 'the laborer can easily cut the spool (80) of wrap from the object being wrapped with a tearing motion. The assay (60) enables the laborer to be efficient in the quantity of the wrap on the spool (80). Arm (60) pivots within channel (65), the second part of the assay (58), so that arm (60) that can be depressed to stop the turning of the spool (80). The third part

- 6 -Nelson E. Phero 43 Beebetown Road Hammontown, NJ 08037 of the assay (60) is the sleeve (68) ~~hich fits around pole (10). The sleeve (68) provides a mounting surface for the channel (6_'i), and sleeve (68) rotates about pole (10).
The present invention can be utilized to assist in wraps above and below the laborers normal grasp of reach. The long lenl;th of the pole ( 10) allows for easy access to high beds of objects, while still having versatility in objects low to the ground or on the floor. The elimination of kneeling and squatting to wrap objects will greatly reduce discomfort and possible injury in the wrapping process.
Primarily, the present invention is intended to be used in the wrapping of items with a hand held non-motorized device, as in a warehouse for shipping or storing. It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
