Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for facilitating replacement of a roll of material, such as a toilet paper roll, where the roll is held on a mandrel assembly including a telescoping tube assembly in which a first tube is received in a second tube and a spring is located between them to bias the tubes away from each other. The roll replacement facilitating device of the present invention facilitates compression of the spring and movement of the second tube toward the first tube so that the tube assembly can be removed from a holder to insert a new roll of material on the mandrel assembly.
2. Description of the Prior Art
Heretofore various mandrel or telescoping tube assemblies have been proposed for holding a roll of material, such as a toilet paper roll. Also some of these mandrel or tube assemblies have included a radially projecting flange or tab extending radially outwardly from one of the tubes to facilitate movement of one tube against another tube of the mandrel or tube assembly. These prior structures require a special construction of one or both of the telescoping tubes and do not include a structure which can be mounted on or used with a conventional tube or mandrel assembly for a toilet paper roll. Also, there have been proposed, a mandrel or tube assemblies which permit the mounting of fragrance dispensing materials in the mandrel or tube assembly.
Some examples of previously proposed mandrel or tube assemblies for mounting a toilet paper roll and assemblies for dispensing a fragrance from the tube or mandrel assembly are disclosed in the following analogous and non-analogous U.S. Patents:

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings in greater detail there is illustrated in
FIG. 1
a mandrel or tube assembly
10
comprising a first larger tube
12
and a second smaller tube
14
. Hidden from view within the tubes
12
and
14
is a spring such that the first and second tubes
12
and
14
are urged away from each other by the compressive force of the spring. This structure is conventional and forms no part of the present invention.
As shown in phantom, a roll
16
of toilet paper is positioned on the tube assembly
10
.
According to the teachings of the present invention, at least one plate
18
, which, in the illustrated embodiment is a laminated disc
18
, is positioned on a stepped shoulder
20
at the end of the larger tube
12
. While the disc
18
is shown mounted on a stepped shoulder of the larger tube
12
, it alternatively can be mounted on a stepped shoulder
22
of the smaller tube
14
. The plate or disc
18
is constructed with a hole
24
, which is sized to fit over and on the shoulder
20
and/or
22
.
With reference to
FIG. 5
, it will be appreciated that a user can engage the plate or disc
18
with a forefinger to move the first larger tube
12
telescopingly over the smaller tube
14
to compress the tube assembly
10
to facilitate removal of the tube assembly
10
from a U-shaped holder
30
for removal of the used roll
16
and insertion of a new roll
16
of toilet paper on the tube assembly
10
and into the holder
30
.
The holder
30
includes a base
32
for mounting on a wall and spaced apart, outwardly extending legs
34
and
36
. The legs
34
,
36
each have a width which is less than the diameter of the disc shaped plate
18
so that the plate
18
extends beyond the adjacent leg
34
or
36
to expose part of an outer surface
38
of the plate
18
which also has an inner surface
40
.
While the plate or disc
18
can be made of several different materials including wood, cardboard, rubber, plastic, and metal, a stiff plastic material is preferred for the inner ply
42
. The embodiment illustrated in the drawings includes the stiff inner ply
42
and a softer outer ply
44
, such as a fabric ply, which easily can be impregnated with a fragrance, a deodorizing substance or an air freshener for neutralizing odors.
Also, it will be understood that the plate
18
can be made of one material only, with or without impregnation with a fragrance or deodorizer.
The outer disc or ply
44
of fabric material can be made of any fiber which will hold a fragrance such as an animal fiber or hair, a vegetable fiber (e.g. cotton) or a plastic fiber.
As shown in
FIG. 6
, two discs or plates
18
can be employed, one at each end of the tube assembly
10
. This will facilitate compression of the tube assembly since a user can engage one plate
18
with a forefinger and the other plate
18
with a thumb and squeeze to remove the tube assembly
10
from the holder
30
. However, this modified construction will require removal of one of the discs
18
for insertion of a roll
16
of toilet paper.
The construction shown in
FIGS. 1
,
2
and
5
, is preferred since it enables easy removal of the used paper roll
16
and replacement with a new paper roll
16
simply by engaging the plate
18
with the forefinger and one leg
34
or
36
of the holder
30
with the thumb and squeezing to compress the tube assembly
10
for facilitating its removal.
Also it will be understood that while a circular plate or disc
18
is illustrated in the drawings, the plate
18
can have a shape selected from one of: circular, square, rectangular, a geometric design or the two dimensional shape of a creature or character.
In
FIGS. 7 and 8
is illustrated a modified plate structure
50
which includes at least one stiff plate
52
and a sleeve
54
fixed to and extending from an inner surface
56
of the plate
52
. The sleeve
54
has an inner diameter which will fit over at least part of the tube assembly
10
and with the cardboard roll of a toilet paper roll
16
. In this constuction, the sleeve
54
and not a hole
24
in the plate or disc
18
, forms a means for mounting the plate structure
50
on a tube assembly
10
.
From the foregoing description it will be appreciated that the combination tube assembly
10
and plate
18
or plate structure
50
of the present invention, provides a number of advantages some of which have been described above and others of which are inherent in the invention. For example, the disc shaped plate
18
facilitates easy compression of the tube assembly
10
and removal of the tube assembly
10
from the holder
30
for replacing a roll
16
of material on the tube assembly
10
. The disc shaped plate
18
can be used with any conventional tube assembly or mandrel assembly
10
for holding a roll
16
of toilet paper as long as the disc
18
has an outer diameter which extends beyond the width of the adjacent leg
34
or
36
of a holder
30
, as shown in
FIG. 6
, and has an inner diameter hole
24
which is sized to be receive over a step or shoulder
20
or
22
at one end of one tube
12
or
14
of a tube assembly
10
for holding a toilet paper roll
16
. This facilitates use of the plate or disc
18
with existing mandrel or tube assemblies
10
for holding a toilet paper roll
16
.
Still further, the disc
18
can be stiff, of one piece construction and impregnated with an air freshener or fragrance for neutralizing odors in the bathroom. In one preferred embodiment, the disc
18
is a laminated assembly
18
comprising a stiff inner disc
42
and a fragrance impregnated outer fabric disc
44
.
It will be understood that when a fragrance impregnated plate or plate assembly
18
is utilized, different fragrances can be provided and after a period of use can be replaced with a new disc
18
with the same or new fragrance.
Furthermore, as shown in
FIG. 6
two disc or disc assemblies can be utilized to facilitate compression of the tube assembly.
Also, it should be understood that modifications can be made to the combination tube assembly
10
and plate
18
or plate structure
50
of the present invention without departing from the teaching of the present invention. For example, while a circular plate or plate structure is illustrated in the figures of the drawings, the shape of the disc can be altered as desired to a square shape or to the shape of a selected geometrical design or to the two dimensional shape of a creature or character.
Also, the plate
18
can have a larger than required hole
24
and an annular rubber disc can be added having an outer diameter substantially the same as or larger than the hole
24
and having an inner diameter sized to frictionally fit over a shoulder
20
or
22
at the end of one of the tubes
12
or
14
. In this way, the plate
18
can be fixed frictionally to the shoulder
20
or
22
. Stated otherwise, this construction facilitates a friction fit of the plate
18
on a shoulder
20
or
22
.
Accordingly, the scope of the invention is only to be limited as necessitated by the accompanying claims.
