Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit under 35 U.S.C. .sctn.
119(e) of U.S. Provisional Patent Application Ser. No. 60/520,961,
entitled MODULAR HOSE REEL, filed on Nov. 18, 2003.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to reels for storing hoses,
electrical cords, ropes, cables, or other items. In particular, the
present invention relates to a reel including a modular base
assembly and a modular spool assembly.
[0004] 2. Description of the Related Art
[0005] Reels are used to store elongate items such as hoses for
delivering fluids, including water, air, hydraulic fluid, or
grease, for example. Such hoses may be round or flat in shape, and
may also be used in vacuum applications for removing a fluid or a
solid substance from a given location. Alternatively, reels may be
used to store elongate items other than hoses, such as electrical
cords, ropes, cables, or other items.
[0006] Known reels typically include a base assembly and a spool
assembly. In one known hose reel, for example, the base assembly
includes a frame made from a number of different, individually
formed metal components attached to one another with screw
fasteners. The metal components are typically formed by stamping
and bending operations. The components of the frame include a pair
of side walls which include bearings for supporting the spool
assembly, and one or more cross members connecting the side walls
to one another. The spool assembly includes a pair of round,
opposed sides attached to opposite ends of a cylindrical hub, which
is rotatable on an axle carried in the bearings of the side walls
of the base assembly. The base assembly also includes an inlet
fitting for connection to a fluid source, and the spool assembly
includes an outlet fitting to which a hose is attached for
conveying the fluid from the inlet fitting into the hose. A hand
crank may be provided to rotate the spool assembly for manual
unwinding and/or winding of the hose.
[0007] A problem with the foregoing hose reel is that the base
assembly and the spool assembly are each made of different, formed
metal components having particular dimensions, such that the reel
may be assembled only to a single, predetermined overall size.
However, because hose reels are typically used in many different
types of applications, any single, predetermined size of the hose
reel may not be suitable for each application. For example, when
the hose reel is used in a large building such as a warehouse,
space constraints typically do not pose a problem and the hose reel
may be relatively large in size. However, when the hose reel is
used on a truck, for example, space may be at a premium and the
size of the hose reel is subjected to space constraints.
Additionally, a hose reel of a particular size may not be able to
accommodate different types of hoses with varying thicknesses and
diameters.
[0008] When a hose reel manufacturer manufactures a number of
different hose reels having different sizes, this requires the
manufacturer to produce and stock a very large inventory of
different, pre-sized, formed components, such as the formed metal
components of the frame of the base assembly and the formed metal
components of the spool assembly. In this manner, known hose reels
must be manufactured to a number of specific, predetermined
dimensions and sizes in order to suit different particular
applications, which requires production, inventory, and assembly of
a number of different components, and increases the cost of
manufacturing the hose reels.
[0009] What is needed is a reel for hoses, electrical cords, ropes,
cables, or other items which is an improvement upon the
foregoing.
SUMMARY OF THE INVENTION
[0010] The present invention provides a reel, such as a hose reel,
which includes a modular base assembly and a modular spool
assembly. The base assembly includes a frame which is formed by a
plurality of extruded frame components joined to one another by
connecting members. The lengths of the frame components may be
easily varied in order to in turn vary the overall width, depth,
and height dimensions of the frame of the base assembly. The spool
assembly includes a pair of side walls joined to one another by a
plurality of spacer members. The length of the spacer members may
be varied to in turn vary the width of the spool assembly. In one
embodiment, the base assembly frame components and the spacer
members are aluminum extrusions which are each cut to a selected
length. In this manner, the width, depth, and height of the frame
of the base assembly and the width of the spool assembly may be
selectively varied to easily custom manufacture different reels
having different overall sizes.
[0011] The modular design of the base assembly and the spool
assembly of the present reel allows a manufacturer to produce a
number of reels having varying sizes and dimensions using the same
type of frame components for the frame of the base assembly and the
same type of spacer components for the spool assembly in each reel.
The dimensions of the base assembly and the spool assembly may be
modified simply by modifying the lengths of the frame components of
the base assembly and the lengths of the spacer members of the
spool assembly. Thus, a manufacturer may custom produce reels of
any size in order to suit any particular application having
differing requirements such as size constraints and hose length or
diameter, for example. Additionally, the reel manufacturer need
produce and stock a large number of pre-formed frame components in
order to product reels of different sizes, as with known reel
constructions. The hose reel may also be shipped in disassembled
form to reduce shipping costs, and the hose reel is easily
assembled by a purchaser.
[0012] Additionally, the modular design of the base assembly and
the reel assembly of the present reel allows a reel manufacturer to
provide varying options for unwinding and/or winding a hose or
other item upon the reel. For example, the base assembly may be
fitted with a hand crank for manual cranking of the spool assembly
for unwinding and/or winding a hose or other item, or
alternatively, a motor may be attached to the base assembly for
driving the spool assembly to provide motor-driven unwinding and/or
winding of a hose or other item. The motor and spool assembly may
be drivingly coupled by a gear drive or by a chain and sprocket
drive, for example. The frame components of the base assembly are
configured to adjustably receive add-on items as necessary, such as
a hand crank mechanism.
[0013] In one form thereof, the present invention provides a line
of reels, including a first reel including a first base assembly
formed of a plurality of frame components joined to one another,
the first base assembly having a height, a width, and a depth; a
second reel including a second base assembly formed of a plurality
of frame components joined to one another, the second base assembly
having a height, a width, and a depth, at least some of the frame
components of the first and second base assemblies formed as
extrusions having an identical cross sectional shape, and at least
one of the height, width, and depth of the second base assembly
differing from the height, width, and depth of the first base
assembly; each of the first and second base assemblies of the first
and second reels including a spool assembly rotatably mounted
thereto.
[0014] In another form thereof, the present invention provides a
method of manufacturing reels, including the steps of forming a
plurality of individual frame members by extrusion, at least some
of the frame members having identical cross sectional shapes, and
at least some of the frame members having different lengths;
attaching individual frame members to one another to form a first
base assembly having a height, a width, and a depth; mounting a
rotatable spool assembly to the first base assembly; attaching
individual frame members to one another to form a second base
assembly having a height, a width, and a depth, wherein at least
one of the height, width, and depth of the second base assembly
differs from the height, width, and depth of the first base
assembly; and mounting a rotatable spool assembly to the second
base assembly.
[0015] In a further form thereof, the present invention provides a
reel, including a base assembly including a plurality of individual
frame components having slots extending therealong, the frame
components joined to one another by connectors received within the
slots; and a spool assembly rotatably mounted to the base
assembly.

DETAILED DESCRIPTION
[0037] Referring first to FIGS. 1 and 2, a exemplary reel 20 in
accordance with the present invention is shown in the form of a
hose reel. Although reel 20 is described below as a hose reel for
use in storing a hose 26, it should be understood that the reels 20
according to the present invention may also be used with electrical
cords, ropes, cables, or other elongate items in a variety of
different applications. Hose reel 20 generally includes base
assembly 22 and spool assembly 24 rotatably mounted to base
assembly 22, with spool assembly 24 holding a hose 26 or other
elongate item wound thereon.
[0038] Referring to FIG. 3, base assembly 22 generally includes
base frame 28 formed of a plurality of frame components 30
connected to one another as described below. Frame components 30
may be formed as extrusions, such as aluminum extrusions, for
example. Alternatively, frame components 30 may be formed from a
rigid plastic via an injection molded or an extrusion process. Base
frame 28 includes a pair of horizontally disposed frame components
30a which primarily define a width dimension "W" of frame 28 and
base assembly 22, two pair of vertically disposed frame components
30b at opposite sides of frame 28 which primarily define the height
dimension "H" of frame 28 and base assembly 22, and a pair of
horizontally disposed frame components 30c which primarily define
the depth dimension "D" of frame 28 and base assembly 22.
[0039] Referring to FIG. 4, frame components 30a-c are identical,
and have an identical cross-sectional shape with a square profile,
including internal portion 32 with central bore 34, and four
external portions 36 extending from internal portion 32 which
define four T-slots 38 therebetween, one in each of the side faces
of frame component 30. Each T-slot 38 includes an outwardly-facing
channel 40 and a pair of opposing flanges 42 having blind, internal
surfaces.
[0040] Frame components 30a-c may be attached to one another using
connectors 44 shown in FIGS. 5 and 6. Connectors 44 may be
Power-Lock.TM. connectors, available from MiniTec, Inc., of Victor,
N.Y. Connectors 44 are similar to those disclosed in German Patent
DE 4 127 284 C1. Referring to FIG. 5, each connector 44 includes
base 46 having a pair of opposing ledges 48, and first and second
projections 50 and 52, with first projection 50 including a first
bore 54 therethrough and second projection 52 including a second
bore 56 (FIG. 6) therethrough which is disposed at an angle with
respect to first bore 54. As shown in FIG. 6, a set screw 58 is
threaded within second bore 56 and, as shown in FIG. 5, a bolt 60
having threaded shaft 62 and head 64 is inserted through first bore
54.
[0041] Referring to FIGS. 5 and 6, to connect any two frame
components 30a-c to one another, such as a frame component 30b to a
frame component 30c, for example, a connector 44 is pressed into
the end of frame component 30b, with first projection 50 of
connector 44 inserted within central bore 34 of frame component
30b, and second projection 52 of connector 44 inserted within a
T-slot 38 of frame component 30b. Thereafter, bolt 60 is rotated by
a suitable tool to tap threaded shaft 62 of bolt 60 into threading
engagement with central bore 34 of frame component 30b until head
64 of bolt 60 is disposed proximate base 46 of connector 44, as
shown in FIG. 6. As shown in FIG. 4, central bore 34 of frame
component 30b includes relief slots 35 which facilitate the
self-tapping of threaded shaft 62 of bolt 60 into central bore 34.
In this manner, connector 44 is securely fastened to frame
component 30b.
[0042] Thereafter, as shown in FIG. 6, base 46 of connector 44 is
inserted within T-slot 38 of frame component 30c along the
direction of arrow A.sub.1 such that ledges 48 of base 46 of
connector 44 engage behind the pair of opposing flanges 42 of
T-slot 38 of frame component 30c, with head 64 of bolt 60 disposed
within channel 40 of the T-slot 38. When frame component 30b is
slidably positioned at a desired location with respect to frame
component 30c, a tool 66 is inserted into T-slot 38 of frame
component 30b to rotate set screw 58 (see arrow A.sub.2 in FIG. 6)
such that set screw 58 engages head 64 of bolt to press ledges 48
of base 46 of connector 44 into firm engagement with flanges 42 of
T-slot 38 of frame component 30c to secure frame components 30b and
30c to one another. Each of the other frame components 30a-c of
frame 28 of base assembly 22 are assembled in this manner to form
frame 28. As may be seen in FIG. 3, for example, after connectors
44 are used to connect respective frame components 30a-c,
connectors are not visible but rather are hidden from view.
Optionally, caps (not shown) may be inserted into the open ends of
frame components 30a-c after connection to provide a finished
appearance.
[0043] Referring to FIG. 7, side brackets 68 of base assembly 22
are mounted between adjacent vertical frame components 30b by
inserting bolts 70 through apertures 72 in flanges 74 of side
brackets 68 and into threaded engagement with corresponding nuts 76
which are non-rotatably captured within channels 40 of T-slots 38
of frame components 30b. Bolts 70 are thereafter tightened to
capture flanges 74 of side brackets 68 between bolts 70 and frame
components 30b to secure side brackets 68 to frame components 30b.
Side brackets 68 may be used to support an electric motor 136 of a
power drive assembly, as described below, or other items, on base
assembly 22. Additionally, gussets 78, shown in FIGS. 2 and 3, may
be attached to frame components 30a and 30b of frame 28 using bolts
70 and nuts 76 in the same manner described above with regard to
side brackets 68, in order to support the 90.degree. connections
between frame components 30a and 30b.
[0044] Referring to FIG. 8, spool assembly 24 is shown, which
generally includes a pair of side walls 80 connected by a plurality
of spacer members 82. Side walls 80 are each shown as circular in
shape, and include concentric, recessed first and second step
portions 84 and 86, with first step portion 84 having a greater
diameter than second step portion 86. Side walls 80 further include
a set of first apertures 88 for attachment of spur gear 90, as
described below, and two sets of second apertures 92 (FIG. 10), one
in each of first and second step portions 84 and 86, for attachment
of spacer members 82, as described below. Referring to FIG. 11,
each of spacer members 82 is formed as an extrusion, such as an
aluminum extrusion, having a quarter-round profile, with each
spacer member 82 including a quarter-round face 94 and central bore
96.
[0045] Referring to FIG. 9, spur gear 90, which is annular in shape
and includes teeth around its periphery, is attached to an outer
side of one of side walls 80 of spool assembly 24 by bolts 98
inserted through apertures in spur gear and apertures 88 in side
wall 80. Spacers 100 and nuts 102 cooperate with bolts 98, with
spacers 100 spacing spur gear 90 outwardly a distance from the
outer side of side wall 80. Additionally, referring to FIG. 10,
side walls 80 of spool assembly 24 are attached to the ends of
spacer members 82 with suitable screws 104, which are inserted
through second apertures 92 in side walls 80 and which tap into
central bore 96 of spacer members 82. Screws 104 may additionally
include concave rubber washers which are captured between the heads
of screws 104 and the outer sides of side walls 80 to absorb
vibration. Further, referring to FIG. 8, spacer members 82 are
disposed such that quarter round surfaces 94 thereof face radially
outwardly for receipt of hose 26 wound onto spacer members 82 of
spool assembly 24. In this manner, spacer members 82 together
define a cylindrically-profiled spool upon which a hose or other
elongate item may be wound. Side walls 80 each further include
openings 105 for mounting input connector assembly 114 and bearing
108 to spool assembly 24, as discussed below, for rotatably
supporting spool assembly upon axle 106.
[0046] Generally, the overall width of spool assembly "W.sub.s"
(FIG. 8) is determined by the length of spacer members 82.
Advantageously, by varying only the length of spacer members 82,
the width "W.sub.s" of spool assembly 24 may be varied as desired
to in turn vary the hose storage capacity of spool assembly 24.
Also, the diameter of side walls 80 may also be varied to vary the
hose storage capacity of spool assembly 24. Further, spacer members
82 may be attached to first step portion 84 of side walls 80, as
shown in FIG. 10, such that the spacer members 82 together provide
a relatively larger spool diameter for hoses having a relatively
larger diameter or larger bend radius. Alternatively, spacer
members 82 may be attached to second step portion 86 of side walls
80 to provide a relatively smaller spool diameter for hoses 26
having a relatively smaller diameter or smaller bend radius. Thus,
the length of spacer members 82, the diameter of side walls 80, and
the attachment of spacer members 82 to either the first or second
step portions 84 or 86 of side walls 80 are each design variables
of spool assembly 24 which may be selectively controlled to vary
the hose storage capacity of spool assembly 24 based upon the
length and diameter of the hose 26 which is to be used with reel
20.
[0047] Spool assembly 24 is mounted to base assembly 22 as shown in
FIGS. 12-14. Referring to FIG. 12, after installation of input
connector assembly 114 and axle 106 on spool assembly 24, spool
assembly 24 is lowered onto base assembly 22 such that side walls
80 of spool assembly 24 are disposed between the opposite sides of
base assembly 22, to thereby position spool assembly 24 within base
assembly 22. Thereafter, referring to FIG. 13, bearing 108, which
rotatably supports one end of axle 106 of spool assembly 24, is
mounted to the top face of one of frame components 30c using a pair
of bolts 110 and associated nuts 112, with bolts 110 inserted
through pre-drilled holes (not shown) in frame components 30c.
[0048] Concurrently, as shown in FIG. 14, at the opposite side of
reel 20, input connector assembly 114 is mounted to the top face of
one of frame components 30c using a pair of bolts 10 and associated
nuts 112, with bolts 110 inserted through pre-drilled holes (not
shown) in frame components 30c. Input connector assembly 114
includes a ball bearing therein (not shown) for supporting one end
of axle 106 of spool assembly 24, and additionally includes an
inlet hose fitting 116 to which an inlet source of fluid may be
attached, such as a water hose, for example, using suitable clamps
or other fasteners.
[0049] Referring to FIG. 15, outlet connector assembly 118 is
disposed within the interior of spool assembly 24, and is fluidly
connected to input connector assembly 114. Output connector
assembly 118 includes neck portion 120 with an outlet hose fitting
to which an end of hose 26 may be connected using suitable clamps
or other fasteners. A portion of hose 26 is visible in FIG. 15. In
operation, fluid from a fluid source is conveyed to input connector
assembly 114, such as through a hose, for example, and is thence
conveyed through output connector assembly 118 to hose 26.
[0050] Referring to FIG. 2, a first, manual drive assembly for reel
20 includes hand crank mechanism 124, with bearing support 126
attached to frame 28 of base assembly 22. Axle 128 is supported by
bearing support 126, and handle 130 and bevel gear 132 are mounted
at opposite ends of axle 128, with bevel gear 132 meshing with an
annular bevel gear 134 attached to one side wall 80 of spool
assembly 24. Manual rotation of handle 130 by an operator rotates
axle 128 and bevel gear 132, which engages bevel gear 134 of spool
assembly 24 to rotate spool assembly 24 upon axle 106 to wind
and/or unwind hose 26 on spool assembly 24.
[0051] Alternatively, a second, power drive assembly for reel 20
includes electric motor 136 mounted to a side bracket 68 of frame
28 of base assembly 22. Referring to FIG. 16, motor 136 includes
output shaft 138 to which a pinion gear 140 is mounted, and pinion
gear 140 is in meshing engagement with spur gear 90 mounted to a
side wall 80 of spool assembly 24, as discussed above. In
operation, motor 136 drives pinion gear 140 to in turn drive spur
gear 90 to rotate spool assembly 24 upon axle 106 to wind and/or
unwind hose 26 on spool assembly 24. A suitable control mechanism
142 (FIG. 1) may be associated with motor 136 to control the
operation thereof. Alternatively, motor 136 may drive spool
assembly through a chain drive, for example, as discussed below
with respect to the embodiment of FIG. 19.
[0052] In the reels shown in FIGS. 1, 2 and 12-18, bearings 108 are
attached to the top face or upper side of frame component 30c such
that spool assembly 24 is disposed substantially externally of base
assembly 22. Referring to FIG. 19, a reel 20 is shown according to
an alternate embodiment, which includes bearings 108 mounted to the
lower face or lower side of frame component 30c by a pair of bolts
110 and associated nuts 112, with bolts 110 inserted through
pre-drilled holes (not shown) in frame components 30c. In this
manner, spool assembly 24 is disposed substantially internally of
base assembly 22. In this embodiment, when reel 20 is hung in an
upside-down position or used with a movable vehicle, for example,
in the very unlikely event that bolts 110 should break or otherwise
fail, spool assembly 24 will not separate from base assembly 22,
but rather will remain trapped within base assembly 22. Reel 20 of
FIG. 19 also includes an alternate drive mechanism for spool
assembly 24, including sprocket 144 attached to drive shaft 138 of
motor 136, which drives a toothed gear 146 of spool assembly 24 via
chain 148.
[0053] Advantageously, the overall dimensions and sizes of reel 20
may be easily varied by varying the length of frame components
30a-c of base assembly 24 and/or the length of spacer members 82 of
spool assembly 24. Thus, the modular design of base assembly and
spool assembly allows a manufacturer to produce hose reels 20 of
varying dimensions in order to suit particular applications having
differing requirements, such as size constraints and hose length,
and the manufacturer need not produce and stock a large number of
pre-formed frame components in order to product reels of different
sizes, as with known reel constructions. Further, the easy assembly
of base assembly and spool assembly allows the manufacturer to ship
reel 200 disassembled to reduce shipping costs.
[0054] One exemplary reel 20, which is shown in FIGS. 1 and 2 and
discussed above, includes base assembly 22 and spool assembly 24 of
an intermediate width "W" (FIG. 2). Referring to FIG. 17, another
exemplary reel 20 is shown, in which the lengths of frame
components 30a of base assembly 22 and the length of spacer members
82 of spool assembly 24 have been reduced to provide a reel 20
which is relatively narrow in width "W" as compared to reel 20 of
FIGS. 1 and 2. Referring to FIG. 18, a further exemplary reel 20 is
shown, in which the lengths of frame components 30a of base
assembly 22 and the length of spacer members 82 of spool assembly
24 have been increased to provide a reel 20 which is relatively
wide in width "W" as compared to reels 24 of FIGS. 1, 2, and 17.
Similarly, the lengths of frame components 30b may be varied to in
turn vary the height of reel 20, and the lengths of frame
components 30c may be varied to in turn vary the depth of reel 20.
In this manner, a manufacturer of reels 20 may vary the overall
dimensional sizes of the reels 20 simply by varying the length of
frame components 30a-c of frame 28 of base assembly 22 and the
length of spacer members 82 of spool assembly 24.
