Abstract
A support arm for supporting a paper towel roll, having selected openings in one end, in a paper towel dispenser, and having a dispenser engaging arm portion, a cylindrical portion affixed to the arm portion, and an outer sleeve abutting a first side of the cylindrical portion. An inner sleeve slidably engages a second side of the cylindrical portion. An interconnecting structure interconnects the inner and outer sleeves and is insertable into the selected openings in the end of the paper towel.
Description




FIELD




The present invention relates to a paper towel holder for supporting a roll of paper in a paper towel dispenser.




BACKGROUND




Commercial paper towel dispensers must support a large roll of paper towel material so that the roll can rotate in response to pulling on the leading edge of the paper. Various marketing strategies have been employed in marketing paper towel dispensers and paper towel material. One such strategy has been for paper companies to sell the paper towel material directly to the customer and the paper towel dispenser manufacturers to sell their dispensers independently of the paper towel suppliers to the same customers. This strategy requires the customer to deal with two different suppliers rather than just one. Recently paper manufacturers have taken on the role of supplying not only paper but also the dispensers. Accordingly, a great deal of interest has developed in ways of ensuring only the paper of a particular manufacturer can be used with a particular dispenser.




Accordingly, it is an object of the invention to provide a paper towel roll holder that can be used with only paper towel rolls of a particular paper company.




SUMMARY OF THE INVENTION




According to the invention there is provided a support arm for supporting a paper towel roll, the roll having selected openings in one end, in a paper towel dispenser, and having a dispenser engaging arm portion, a cylindrical portion affixed to the arm portion, and an outer sleeve abutting a first side of the cylindrical portion. An inner sleeve slidably engages a second side of the cylindrical portion. An interconnecting structure interconnects the inner and outer sleeves and is insertable into the selected openings in the end of the paper towel.




The selected openings may include a cylindrical opening in a center of the roll and slots cut into the end of the roll from the cylindrical opening in a preselected orientation.




Preferably the inner sleeve is slidably insertable into the cylindrical opening in the end of the roll.




The interconnecting structure may be a plurality of radially directed webs extending outwardly of the inner sleeve.




Advantageously, the inner sleeve has a plurality of tabs with outwardly directed shoulders which can be press-fitted through an opening in a center of said cylindrical portion and snap out such that the shoulders lock onto a back surface of the cylindrical portion.











BRIEF DESCRIPTION OF THE DRAWINGS




Further features and advantages will be apparent from the following detailed description, given by way of example, of a preferred embodiment taken in conjunction with the accompanying drawings, wherein:





FIG. 1

is an exploded perspective view of a paper towel roll with a pair of roll support arms according to a preferred embodiment of the present invention;





FIG. 2

is front elevation view of the roll support arm which fits only paper towel rolls having three equi-spaced slots; and





FIG. 3

is an end view of the end of a paper towel roll that has three equi-spaced slots.











DETAILED DESCRIPTION WITH REFERENCE TO THE DRAWINGS




Referring to

FIG. 1

, a large roll of paper towel material


38


has notches


36


cut into one end from an inner sleeve


40


into the paper. An arm support


10


has a rotatable cylindrical inner sleeve portion


16


and outer sleeve portion


18


interconnected with radially directed webs


20


. A cylindrical portion


42


of arm support


10


forms the base around which inner sleeve portion


16


rotates. Inner sleeve portion


16


has three guides


44


each with a shoulder that loosely engages the back of cylindrical portion


42


. Outer sleeve portion


18


rotates against cylindrical portion


42


. Together outer sleeve portion


18


and guides


44


constrain the inner and outer sleeve portions


16


and


18


to rotational movement.




Arm region


12


has shoulder


46


and prongs with abutments


48


which cooperate and engage a back of a dispenser panel (not shown) to hold arm support


10


rigidly against the back of the dispenser panel and, hence, support the roll


38


. A similar arm support


50


is used on the opposite end of roll


38


except that it has no webs


20


to engage slots in roll


38


.




It will be appreciated that in order to be mounted on arm support


10


a roll must have slots


36


. Without such slots roll


38


could not pass over webs


20


. If a user were to attempt to remove webs


20


, inner sleeve would disengage from outer sleeve


18


causing inner sleeve


16


to fall through the hole in cylindrical portion


42


and the outer sleeve to fall away. Thus, the purchaser of the dispenser (not shown) having the arm supports


10


and


50


would have to purchase paper towel rolls having slots


36


or else cut his/her own slots


36


.




It will be further understood that any number of slots could be used in any desired orientation as long as the number and orientation of the webs


20


is the same. Although webs


20


are preferred, there are other elements that could be used such as pins and corresponding holes drilled into the end of the paper roll.




Accordingly, while this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications of the illustrative embodiments, as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to this description. It is therefore contemplated that the appended claims will cover any such modifications or embodiments as fall within the true scope of the invention.



Claims
  • 1. A support arm for supporting a paper towel roll, said roll having selected openings in one end, in a paper towel dispenser, comprising:(a) a dispenser engaging arm portion; (b) a cylindrical portion affixed to said arm portion; (c) an outer sleeve abutting a first side of said cylindrical portion; (d) an inner sleeve slidably engaging a second side of said cylindrical portion so as to rotate within said cylindrical portion with rotation of said paper towel roll; and (e) an interconnecting structure interconnecting said inner and outer sleeves and insertable into said selected openings in the end of said paper towel roll.
  • 2. A support arm according to claim 1, wherein said selected openings include a cylindrical opening in a center of said roll and slots cut into the end of said roll from said cylindrical opening in a preselected orientation.
  • 3. A support arm according to claim 2, wherein said inner sleeve is slidably insertable into the cylindrical opening in the end of said roll.
  • 4. A support arm according to claim 1, wherein said interconnecting structure is a plurality of radially directed webs extending outwardly of said inner sleeve.
  • 5. A support arm according to claim 1, wherein said inner sleeve has a plurality of tabs with outwardly directed shoulders which can be press fitted through an opening in a center of said cylindrical portion and snap out such that said shoulders lock onto a back surface of said cylindrical portion.
  • 6. A support arm according to claim 4, wherein breaking of said webs results in said inner and outer sleeves becoming disengaged from said cylindrical portion.
