Abstract
A wire reel assembly comprises a reel, a reel support and a reel securing assembly. The reel includes a central body and removable sides. The central body is removably mounted to an arm of the reel support thereby allowing one of the removable sides to be disconnected from the central body without requiring disassembly of the reel support. The reel securing assembly is also used as an adjustable brake assembly since it includes a friction element contacting the body of the reel to generate a friction force.
Description
FIELD OF THE INVENTION
The present invention relates to reels. More specifically, the present invention is concerned with a wire reel that approximately indicates the amount of wire remaining on the reel. According to another aspect of the present invention, a wire reel assembly allowing easy replacement of the type of wire mounted to the reel is described.
BACKGROUND OF THE INVENTION
Wire reels assemblies are well known in the art. They usually consist of a reel mounted to a reel support allowing free rotation of the reel.
Two general types of wire reels assemblies exist. The first type of wire reel assemblies is mainly concerned with reels that are not reusable, for example, reels made of cardboard and plywood onto which wire is coiled by the wire manufacturer and that are designed to be discarded when they are empty.
The second type of wire reel assemblies are concerned with reusable reels onto which coils of wire may be mounted and removed. This type of wire reel assemblies are becoming increasingly popular since their use allow the wire manufacturers to supply their coils of wire unmounted to reels, thus reducing production costs. Furthermore, reusable reels are inherently environment friendly.
Known wire reel assemblies of the second type suffer from many drawbacks. For example, they require the reels to be removed from the support to allow the removal of the coil of wire from the reel; they do not provide ways to bind the coil of wire before it is removed from the reel; they do not provide a visual indication of the amount of wire remaining on the reel.
OBJECTS OF THE INVENTION
An object of the present invention is therefore to provide an improved wire reel assembly.
SUMMARY OF THE INVENTION
More specifically, in accordance with the present invention, there is provided a wire reel assembly comprising:
a reel having a central aperture;
a reel support including:
a base provided with first and second ground engaging portions interconnected by a generally inverted Y-shaped assembly having a proximate end and first and second distal ends; the first and second distal ends being mounted respectively to the first and second ground engaging portions;
an arm so mounted to the proximate end of the inverted Y-shaped assembly as to have a free distal end; the arm being configured and sized to rotatably receive the reel; and
a reel securing assembly removably interconnecting the reel and the reel support.
According to a second aspect of the present invention, there is provided an adjustable brake mechanism for a wire reel assembly including a reel having a central aperture and a reel support provided with an arm configured and sized to rotatably receive the reel; the the arm having a proximate end provided with a fixed abutment element having a friction surface, and a distal end; the adjustable brake mechanism comprising a pressure applying element configured and sized to be removably mounted to the distal end of the the arm to bias the reel towards the fixed abutment element to thereby generate a friction force between the friction surface and the reel; the pressure applying element being longitudinally movable with respect to the the arm to modify the friction force.
According to yet another aspect of the present invention, there is provided a wire reel comprising:
a generally cylindrical body having first and second opposite ends;
first and second generally circular sides; the first and second sides being configured and sized to be removably mounted to respective first and second opposite ends of the body; the first and second sides including radially provided marks indicating the amount of wire remaining onto the reel.
It is to be noted that the term “wire” used in the present disclosure and in the appended claims is to be construed as any type of wires that may be wound onto a reel such as, for example, electrical wires, electrical cables, fiber optic cables, telephone cables, cables, ropes and the like.
Other objects, advantages and features of the present invention will become more apparent upon reading of the following non restrictive description of preferred embodiments thereof, given by way of example only with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning now to
FIG. 1
of the appended drawings, a reel
10
according to an aspect of the present invention will be described.
The reel
10
includes a central body
12
formed by two identical semi-cylindrical half shells
14
and
16
, and two identical generally circular sides
18
and
20
. For concision purposes, only half-shell
14
and side
18
will be described in greater details hereinbelow.
The various elements of the reel
10
are advantageously made of plastic material such as, for example, high density polyethylene (HDPE), by means of injection molding. Of course, other materials and/or manufacturing techniques, such as blow molding or rotational molding could also be used.
The half-shell
14
is generally hollow and includes two reinforcing walls
22
and
24
provided with respective semi-circular cutouts
26
and
28
. Each longitudinal end of the half-shell
14
has a semi-cylindrical projection
30
,
32
provided with external threads
31
,
33
. As can be better seen from half-shell
16
, these external threads include longitudinal channels
34
. Semi-circular apertures
36
,
38
are also provided in the projections
30
and
32
. Of course, more than two reinforcing walls, such as walls
22
and
24
could be provided.
As will be easily understood by one skilled in the art, the semi-circular cutout portions
26
,
28
,
36
and
38
are aligned and form, with the complementary cutout portions (not shown) of the half-shell
16
, a circular aperture going through the body
12
when the half-shells are interconnected. Similarly, the external threads
31
and
33
of the half shells
14
and
16
are complementary and form, then the half-shells
14
and
16
are interconnected, a conventional helical thread.
As can be better seen from half-shell
16
, longitudinal channels
39
are provided on the external surface thereof. The purpose of these longitudinal channels will be described hereinbelow.
The half-shell
14
also includes a peripheral projection
40
and a complementary channel
42
. These complementary elements interconnect the two half-shells
14
and
16
. Of course, adhesives or other fastening means (not shown) may be used to secure the two half-shells
14
and
16
. Furthermore, the half-shells
14
and
16
could be welded using an electromagnetic welding process or the projection
40
and channel
42
could be designed to be press fitted or snapped.
When the half-shells
14
and
16
are interconnected to form the body
12
, they may receive the sides
18
and
20
.
The side
18
has a hub
44
, eight spokes
46
integrally formed with the hub
44
and a peripheral portion
48
integrally formed with the spokes
46
.
The hub
44
includes a central aperture
50
provided with internal threads
52
complementary to the external threads
31
,
33
of the body
12
. The aperture
50
allows the side
18
to be screwed to the body
12
. The hub
44
also includes a radial aperture (not shown) configured and sized to receive a Y-shaped rotation preventing element
53
.
The Y-shaped rotation preventing element
53
includes a distal end
54
configured and sized to enter the radial aperture of the hub
44
and contact the threaded external portions of the body
12
. The element
53
also includes two proximate ends
56
contacting a mounting element
58
provided between two adjacent spokes
46
to act as a spring that radially biases the distal end
54
towards the center of the side
18
. Therefore, when the distal end
54
faces a longitudinal channel
34
of the body
12
, the biasing action of the proximate ends
56
will force the distal end
54
therein, thereby preventing further rotation of the side
18
with respect to the body
12
. Of course, the user may manually overcome the biasing force to allow rotation of the side
18
.
The rotation preventing element
53
is advantageously provided to prevent unwanted separation of the side
18
from the body
12
during the operation of the reel
10
.
The peripheral portion
48
is provided with a handle
58
that may be mounted to an aperture
60
via a spring lock
62
allowing the handle
59
to be easily disconnected from the reel
10
.
Every other spoke
46
is provided with radial marks
64
,
66
,
68
and
70
respectively indicating that the approximate amount of wire remaining on the reel
10
is 25%, 50%, 75% and 100% of the capacity of the reel
10
. It is to be noted that these marks are also provided onto the internal surfaces of the spokes (see for example the spokes of the side
20
). This feature of the reel
10
is advantageous since it allows, for example, the user to more precisely determine the amount of wire used when a particular task is over. Similarly, the user may verify the approximate amount of wire remaining onto the reel
10
before beginning a particular task to determine if the reel
10
has enough wire thereon.
Turning now to
FIG. 2
of the appended drawings, a reel support
100
according to another aspect of the invention will be described. The reel support
100
includes a base
102
and a cantilever arm
104
.
The base
102
is provided with first and second generally parallel ground engaging portions
106
,
108
interconnected by a generally inverted Y-shaped assembly
113
having a proximate end
110
and first and second distal ends
112
,
114
; the first and second distal ends
112
,
114
being mounted respectively to the first and second ground engaging portions
106
,
108
. Of course, the ground engaging portions
106
and
108
could be other than straight. For example, they could be arcuate with ends provided in a common plane.
Both ends of each ground engaging portions
106
and
108
are optionally provided with anti-skid elements
115
.
The generally inverted Y-shaped assembly
113
is formed by a first tube
116
defining the proximate end
110
and the first distal end
112
and by a second tube
118
, shorter than the first tube
116
and pivotally connected thereto via a pivotal connection
120
. The second tube
118
defining the second distal end
114
. The pivotal connection
120
between the first and second tubes
116
and
118
allow the support
100
to be pivoted between a supporting position shown in
FIGS. 2
to
4
and a transport position shown in FIG.
5
.
The cantilever arm
104
is generally cylindrical and is so mounted to the proximate end
110
of the inverted Y-shaped assembly
113
as to be generally parallel to the first and second ground engaging portions
106
and
108
. Of course, the arm
104
is sized to rotatably receive the reel
10
via its longitudinal aperture.
The arm
104
includes a circular abutting element
122
fixedly mounted to a proximate end thereof and a circular friction element
123
removably mounted to the abutting element
122
. The circular friction element
123
therefore defining a friction surface of the abutting element
122
. Both the abutting element
122
and the friction element
123
are slightly smaller than the circular surface (formed by the semi-cylindrical projections
30
,
32
) of the body
10
. Of course, the circular shape of the element
122
is not critical and abutting element having other shapes could be used.
The free distal end
124
of the arm
104
is provided with an internally threaded opening
126
and with a longitudinal slot
128
, the purpose of which will be described hereinafter.
The various elements forming the reel support assembly
100
are advantageously secured to one another by welding. Alternatively, these elements could be interconnected by fasteners (not shown) or could even be made of folded tubular material.
A reel securing assembly
130
is also provided to removably secure the reel
10
to the reel support
100
. The reel securing assembly
130
also constitutes an adjustable brake assembly as will be readily apparent by the following description.
The reel securing assembly includes a pressure applying element
132
and a fastener
134
.
The pressure applying element
132
includes a pressure applying surface
136
slightly smaller than the circular surface
35
(formed by the semi-cylindrical projections
30
,
32
) of the body
10
. Therefore, the presence of the pressure applying element
132
will not prevent the user from removing the side
18
from the body
12
.
The pressure applying element
132
includes an aperture (not shown) allowing its installation onto the free distal end
124
of the arm
104
. A longitudinal rotation preventing projection
138
projects into this aperture of the pressure applying element
132
and into the slot
128
of the arm
104
. As will be easily understood by the following description, the pressure applying element
132
is advantageously prevented from rotating with the rotation of the reel
10
.
A central aperture
140
of the element
132
allows a threaded portion
142
of the fastener
134
to pass through and to be screwed in the aperture
126
of the arm
104
.
As will be easily understood by one skilled in the art, clockwise rotation of the fastener
134
will increase the biasing force applied by the pressure applying surface
136
to the circular surface
35
, thereby increasing the friction force between the friction element
123
of the support
100
and the body
12
, that, in turn, increases the reel braking action of the adjustable brake assembly
130
. Indeed, rotation of the fastener
134
causes the longitudinal movement of the pressure applying element
132
with respect to the arm
104
.
The pressure applying element
132
is advantageously made of HDPE to prevent premature wear of both the pressure applying element
132
and of the reel body
12
. Of course, the element
132
could be made of other materials that are advantageously less resistant to wear than HDPE so as to prevent premature wear of the body
12
. Similarly, the friction element
123
of the support
100
is advantageously made of a material that is less resistant to wear than the HDPE material forming the body
12
so as to prevent premature wear of the body
12
. Indeed, it is found advantageous to replace the pressure applying element
132
and/or the friction element
123
instead of replacing the entire body
12
.
As will easily be understood by one skilled in the art, the reel securing assembly
130
could be made of only one element (not shown). However, it would be more complicated to prevent such an element from rotating.
It is to be noted that the brake assembly
130
is advantageous since it prevents wire overrun that may lead to wire entanglement and waste of wire. Furthermore, since the brake assembly is adjustable, each user may modify the tension required to unwind the wire according to personal work habits.
FIG. 3
of the appended drawings illustrates the reel
10
mounted to the support
100
and secured thereto via the reel securing assembly
130
.
Turning now to
FIG. 4
of the appended drawings, the removal of a partially used coil of wire (not shown) from the reel
10
or the insertion of a coil of wire onto the reel
10
will be described.
The first step is to place the support
100
so that the ends
107
,
109
and
111
are on the ground
200
. Then, the user may remove the side
18
by a counterclockwise rotation of the side
18
while manually overcoming the biasing force of the rotation preventing element
53
and preventing the rotation of the body
12
.
The result of the steps described hereinabove is illustrated in FIG.
4
. When the reel
10
is as indicated in this figure, to safely remove the coil of wire from the reel, the user merely has to use a securing element such as twine, string, Ty Rap® fasteners, or the like, to temporarily bind the remaining wire together via at least one of the longitudinal channels
39
. This will allow the user to remove the remaining coiled wire from the reel
10
without causing the coil to be sufficiently deformed as to prevent its reinsertion in the reel
10
.
It is to be noted that the pressure applying element
132
does not prevent the side
18
to be removed from the reel
10
. Similarly, since the arm
104
is a cantilever arm, no disassembly of the support
100
is required to remove the side
18
from the body
12
.
To move the wire reel assembly from one place to another, the reel
10
may be used as a wheel. Indeed, by placing the peripheral portions
48
of both sides
18
and
20
onto the ground, and by pivoting the tube
118
so that it lies parallel to the tube
116
, the ground engaging portion
108
may be used as a handle to pull or push the reel
10
. This configuration of the support
100
and of the reel
10
is illustrated in FIG.
5
.
It is to be noted that the coil of wire may either be installed onto the reel
10
so that it unwinds when the reel rotates clockwise or when the reel rotates counterclockwise. Indeed, the adjustable brake assembly
130
is not affected by the rotation direction.
It is also to be noted that while the support
100
is illustrated as being made of tubular material, advantageously metallic material, the various elements forming the support
100
could also be made of plastic material. Of course, if the support
100
is made of plastic material, various design changes would be required to take into account the characteristics of the material used. Similarly, the support
100
could be made of tubular material having a rectangular or any other suitable cross-section.
If the support
100
is made of metallic tubular material as illustrated in the appended drawings, this metallic material is advantageously a material provided with inherent anti-corrosion properties, such as, for example, galvanized steel, or provided with an anti-corrosion coating. Furthermore, the ends of the various elements are advantageously provided with caps or plugs (not shown) to seal the tubular elements from dirt.
Of course, as will be easily understood by one skilled in the art, by forming the central body
12
with two identical semi-cylindrical half-shells
14
and
16
, and by providing identical generally circular sides
18
and
20
, it is possible to reduce the manufacturing costs of the reel
10
.
Turning now to
FIGS. 6
to
8
, other embodiments of the reel support will be described.
More specifically,
FIG. 6
illustrates a reel support
200
according to the present invention. Since the reel support
200
is very similar to the reel support
100
described hereinabove, only the differences between these supports will be described hereinafter.
A major difference between the reel
200
and the reel
100
is the position and orientation of the arm
104
a which is so mounted to the end
110
of the first tube
116
as to be generally vertical when the ground engaging portions
106
and
108
are supported by a generally horizontal surface. It is to be noted that the end
124
of the arm
104
a
is still a free distal end and that the reel
10
may be mounted and dismounted from the support
200
as described hereinabove with respect to the reel support
100
.
It is to be noted that the reel support
200
may be used to transport a reel
100
that is rotatably mounted thereto. However, the transport position of the reel support
200
is not different from its supporting position since, as will be easily understood by one skilled in the art, the support
200
may be pulled or pushed via the ground engaging portion
108
which defines an angle with the rotation axis of the reel
10
when the support
200
is as illustrated in FIG.
6
. Of course, to allow the use of the reel
10
as a wheel, the reel
10
must be brought in contact with the ground.
Turning now briefly to
FIG. 7
, a reel support
300
according to the present invention will be described.
Again, since the reel support
300
is very similar to the reel support
100
described hereinabove, only the differences between these supports will be described hereinafter.
A major difference between the reel
300
and the reel
100
concerns the position and the orientation of the arm
104
b
which is so mounted to the the first tube
116
as to be an extension thereof. The tube
116
and the arm
104
b
may therefore be a single tube to which the circular abutting element
122
is mounted.
It is to be noted that the end
124
of the arm
104
b
is still a free end and that the reel
10
may be mounted and dismounted from the support
300
as described hereinabove with respect to the reel support
100
.
It is to be noted that the reel support
300
may be used to transport a reel
100
that is rotatably mounted thereto. However, the transport position of the reel support
300
is not different from its supporting position since, as will be easily understood by one skilled in the art, the support
300
may be pulled or pushed via the tube
108
which defines an angle with the rotation axis of the reel
10
when the support
300
is as illustrated in FIG.
7
. Of course, to allow the use of the reel
10
as a wheel, the reel
10
must be brought in contact with the ground.
Finally,
FIG. 8
of the appended drawings illustrates a reel support
400
according to the present invention.
Once again, since the reel support
400
is very similar to the reel support
100
described hereinabove, only the differences between these supports will be described hereinafter.
A major difference between the reel
400
and the reel
100
concerns the position and the orientation of the cantilever arm
104
c
which is so mounted to the end
110
of the tube
116
as to be generally perpendicular to the tube
116
while being in the plane defined by the inverted Y-shaped assembly
113
.
Another difference between the support
400
and the support
100
is that the first and second distal ends
112
and
114
are respectively centrally mounted to the ground engaging portions
106
and
108
. As will be easily understood by one skilled in the art, this position is advantageous since it increases the stability of the support
400
when it is in its supporting position.
It is to be noted that the reel support
400
may be used to transport a reel
100
that is rotatably mounted thereto.
Therefore, as will be easily understood by one skilled in the art, the arm
104
may be positioned in various orientations while allowing the reel support of the present invention to operate as described hereinabove.
Although the present invention has been described hereinabove by way of preferred embodiments thereof, it can be modified, without departing from the spirit and nature of the subject invention as defined in the appended claims.
