DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the embodiments of the presently disclosed invention, examples of which are illustrated in the accompanying drawings.
One of the objects for embodiments may be a roller assembly or kit that includes a roll holder, such as a roller head, supported by a pin that allows for the easy exchange of roll holders without compromising the durability of the assembly. One end of the pin may be adapted to be mounted to a pin holder. The pin holder may be supported by a housing, or one end of the housing may comprise the pin holder. In certain embodiments, the opposite end of the pin may be adapted for a screw-on retainer. The roll holder may be retained on the pin in between the screw-on retainer at one end and the pin holder at the other end. Alternatively, some embodiments may comprise a pin having one enlarged or tapering end and a indentation, slot or groove near the other end adapted for a fastener. The indentation, slot or groove may form a ring along the outer circumference of the pin, and may be adapted for an U-shape washer or fastener. In such embodiments, the roll holder may be retained on the pin in between the enlarged end and the fastener near the other end. The end of the pin having the fastener may be adapted to be mounted to a pin holder.
The object for certain embodiments may concern such an application which enables the interchange of roll holders having varying lengths to support different sized rolls. Embodiments may not be limited, however, to any one application, purpose, example or object. The embodiments may be applicable in virtually any application in which debris may be collected by an adhesive tape wound around a roll mounted on a roll holder assembly. The embodiments of the present devices are well suited for implementation on a telescopic stick for cleaning ceilings and walls.
Existing roller-type solutions for picking up lint fail to provide durable roll holders which may be repeatedly exchanged over an extensive period of time. Prior approaches rely on clip-on roll holders, such as those disclosed in U.S. Pat. No. 6,055,695 which was filed on Jun. 24, 1998. This may work well while the clips continue to retain their structural integrity; however, when applied to repeated use and replacing of rolls, the durability of such roll holders is compromised. In contrast, an embodiment of the present invention may provide the integrity necessary for extended use. Further, an object of an embodiment of the present invention may include the interchangeability of roll holders having varying lengths. An advantage of an embodiment for the presently disclosed invention which does not require same-sized replacement rolls may be appreciated when cleaning locations of limited space and accessibility.
A prospective-view of an embodiment of a roller assembly is shown in FIG. 1.

A pin 6 may be adapted to be inserted into the bore of the roll holder 4. The roll holder 4 may be adapted to be rotate about the pin 6. The outer-surfaces of the adhesive sheets 12 that are wound around the cylindrical roll 11 may be adapted to collect debris such as lint, hair, cobwebs and dust. A pin holder 3 may have a cavity that is adapted to hold one end of the pin 6. A pin retainer 5 may be adapted to be mounted on the opposite end of the pin 6. The opposite end of the pin 6 and the pin retainer 5 may have corresponding threads that are operable for screwing the pin retainer 5 onto the opposite end of the pin 6. The pin holder 3 may be adapted to be supported by a housing 1′. The housing 1′ may comprise an upper housing member 1 and a lower housing member 2. A means for connecting the upper housing member 1 and the lower housing member 2 may include fasteners, clips, screws or adhesives. A connecting member 7 may be adapted to connect the housing 1′ to a handle 8. In certain embodiments, the housing 1′ may comprise a single member, a first end of the housing 1′ may comprise the pin holder 3 that is adapted to hold one end of the pin 6, and the second end of the housing 1′ may be adapted to be secured to the connecting member 7. In some embodiments, the upper housing member 1 may comprise a portion of the pin holder 3 and the lower housing member 2 may comprise the remaining portion of the pin holder 3, and the pin holder 3 may be adapted to hold one end of the pin 6 when the upper housing member 1 and the lower housing member 2 are connected to form the housing 1′.
In some embodiments, the roller assembly may be reusable with a replacement roll 11′ (not shown). The cylindrical roll 11 may be removed from the roll holder 4 and a replacement roll 11′ may be mounted on the roll holder 4. The outer-surface of the replacement roll 11′ may be wound by a plurality of adhesive sheets 12 adapted to collect debris.
In an embodiment of the disclosed roller assembly, the roll holder 4 may be replaceable with a replacement roll holder 4′. The pin retainer 5 may be unscrewed from the opposite end of the pin 6 and the roll holder 4 may be removed from the pin 6. The replacement roll holder 4′ may be mounted on the pin 6 and the pin retainer 5 may be screwed onto the opposite end of the pin 6.
In some embodiments, the roll holder 4 is interchangeable with a replacement roll holder 4′ having a different length than the original roll holder 4. The replacement roll holder 4′ may be adapted for a replacement roll 11′ having a length corresponding to the length of the replacement roll holder 4′. A replacement pin 6′ may have a length corresponding to the length of the replacement roll holder 4′. One end of the replacement pin 6′ may be adapted to be mounted in the cavity of the pin holder 3. The opposite end of the replacement pin 6′ may have threads that are operable for screwing the pin retainer 5 onto the opposite end of the replacement pin 6′. The outer-surface of the replacement roll 11′ may be wound by a plurality of adhesive sheets 12 that are adapted to collect debris.
In certain embodiments, the replacement roll holder 4′ may be ten inches long and the roll holder 4 may be six inches long, or vice versa. The roll holder 4 may be made of pure polystyrene or acrylonitrile butadiene styrene (ABS). The handle 8 may comprise a telescopic handle, in accordance with some embodiments.
