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.
