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.
