Description
FIELD OF THE INVENTION
This invention relates to a device for the distribution of irrigation drip line for use below ground or above ground for plant irrigation systems.
BACKGROUND OF THE INVENTION
Drip systems today are becoming more and more popular due to increased costs of residential water and because drip irrigation systems deliver water directly to the individual plants and not just to zones or areas where plants are growing. By direct delivery to individual plants water costs can be reduced.
The coils of drip tubing for commercial installation come in 500 to 1000 foot lengths. Like any other coiled product, if not placed on a reel, the drip line product is subject to kinking and entanglement. Plus, the weight of such large (500/1000 foot) reels, or even 100 foot reels for home use is more than the average person cares to relocate a plurality of times. Therefore there has developed a need for an easy to use low-cost drip tubing dispenser, especially for commercial users, that is members of the installment industry.
Accordingly, it is a first object to provide a dispenser, preferably with interchangeable reels for various lengths of tubing.
It is a second object to provide a drip line dispenser that is easy to carry.
It is a third object to provide a drip line dispenser that permits controllable metering of drip line tubing.
It is a fourth object to provide a drip line dispenser that is low in cost.
A fifth object is to provide a drip tubing dispensing device that can be operated by one worker.
Thus, there is to be described herein a drip tubing dispenser having a lower base upon which is disposed a bearing housing that supports a rotatable upper base. The upper base has a fixed or removably interchangeable reel thereon for receiving the drip line coil. The reel includes a handle mounted on the top thereof for easy one person metering. A counter can also be employed.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
The invention accordingly comprises the device possessing the features, properties and the relation of components which are exemplified in the following detailed disclosure and the scope of the application of which will be indicated in the appended claims.
For a fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description, taken in conjunction with the accompanying drawings.

SUMMARY OF THE INVENTION
A horizontal oriented dispenser for drip line tubing which has a fixed lower base with an upstanding bearing housing mounted thereon, and an upper base capable of rotation with respect to the lower base, is also mounted to the bearing housing. A reel for holding a coil of drip line tubing is disposed on the upper base.
Optional accessories include a handle mounted on the top of the reel to aide in rotation and a pair of fixed grab bars disposed on the lower or fixed base for carrying the device. A metering means may also be included.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In
FIG. 1
the device
10
of this invention is seen sitting in a typical working environment grass
67
. More often than not, the device will be employed while sitting only in raw dirt such as
66
.
Device
10
, comprises five (5) main sections, which are the lower base
11
, upper base
12
, reel
13
, handle portion
14
, and the rotation means
15
all of which will be discussed.
In
FIG. 2
there is seen the first portion of the first embodiment; namely, the lower base
11
. Base
11
in this embodiment is generally octagonal and has eight outer base pieces of square tubing sections
21
A-
21
H inclusive connected end to end. Disposed inwardly from the center point of each base section-denoted CP but only at two locations for ease of understanding, are a series of eight elongated square tubing sections, usually ½″ in cross section. These radii
23
A-
23
H are all equal in length and extend from the various
21
outer base pieces to a center plate
25
. The radii are each welded or braised to their respective base sections and to the center plate
25
. All of the base pieces are connected in like manner, i.e., by welding or braising, all in the same horizontal plane, to the underside of the center plate
25
, designated
25
B as being the bottom of the center plate
25
. Thus the center plate
25
is disposed above the radii when in an in use position, with all the radii and the outer base pieces being disposed at the ground level in a horizontal disposition.
In
FIG. 3
, the top plan view of the lower base, the center plate's top surface,
25
T is seen overlying the upper face of the square tubing radii
23
A-
23
H. Disposed on the center plate's face
25
T, is bearing housing
27
which is one of the components of the rotation means
15
shown in FIG.
1
. See also FIG.
8
.
FIG. 4
is a diagrammatic view showing part of the lower base; namely, base sections
24
A,
24
B,
24
C,
24
D,
24
G and
24
H, with radius
24
A extending inwardly from base section
23
A. Disposed upon center platform
25
T is bearing housing
27
, more about which will be recited infra. A part of upper base
12
—shown in its entirety in FIG.
5
and fully discussed infra—is seen welded or otherwise attached to the bearing cylinder
27
. For ease and simplicity only radii
23
B,
23
C,
23
G and
23
H are depicted. For additional parts relationship understanding, see FIG.
8
.
Just as with the lower base, here too for the upper base, the radii
26
A-
26
H are welded, bolted or otherwise attached at equiangular separations between two upper center plates
26
T and
26
B. Two plates,
26
T and
26
B are used for both strength and appearance, since there is no issue of the base needing to maintain a level disposition, since it is spaced up from the ground.
In
FIG. 5
we see the upper base
12
similarly configured to lower base
11
, though it need not be. Upper base
12
is also constructed of preferably square ½″ tubing and may be of the same or different diameter as the lower base. In
FIG. 1
, the upper base is of greater cross section than the lower base. Four optional grab bars
40
for manually rotating the upper base are shown attached to the upper base at different locations around the periphery. These grab bars
40
can also be used to stop the rotation of the upper base should the user snatch onto one of them during a period of rotation.
Whereas in
FIG. 8
, the top plate
26
T and bottom plate
26
B are disposed over and beneath the radii respectively. Here in
FIG. 5
, center plates
26
T and B are not separately employed. In this variant, the welding of all of the proximal ends of the radii together negates the need for the plates. The distal ends of the radii are welded or otherwise attached to the respective center points of each base section
22
A-H. Contrast this to the spaced inner termini as per FIG.
8
.
In
FIG. 6
the reel upon which the tubing is placed is seen in perspective, while in
FIG. 7
parts of the reel
29
upon which, the 100, 500 or 1,000 foot coil of drip line tubing is placed are seen in top plan. Each leg of the reel
31
is formed in the shape of an inverted L and has a vertical portion positioned at an angle slightly greater than 90 degrees relative to the horizontal portion
31
B to which
31
A is attached at a preferably slightly rounded interface.
Each of these inverted Ls
31
is evenly spaced apart from the adjacent ones. Eight are shown here, though as few as four at 90 degrees or three at 120 degrees apart may be employed, while six or eight reel sections
31
provides a more stable reel.
All of the reel sections as shown in
FIG. 6
are connected at their distal ends greater than 90 degrees to the upper base as shown here and in FIG.
1
. The proximal ends of all of the inverted L sections are welded to each other and to the optional hub
33
upon which is a handle means mounted as by welding.
Reference is also made to
FIG. 9
which depicts a portion of the structure shown in FIG.
6
. The handle means includes a pair of spaced flanges
35
, each of which has a central throughbore
36
. Both bores
36
are aligned to receive a pin
38
shown in
FIG. 9
to pivotally mount handle
37
thereon. An optional rubber cover
39
similar to a bicycle handle bar grip may be disposed upon handle
37
. Handle
37
is used to quickly turn the reel
29
.
In
FIG. 7
, which is a top plan view of the reel portion of this invention, only the spaced flanges for the handle and not the actual handle are seen for clarity. Each of the segment radii has been designated one of
24
A-
24
H. While 8 segments are shown, due to the fact that an octagon is an easy configuration to assemble,
6
or
10
segments are also envisioned to be within the scope of the invention.
The discussion now turns to
FIG. 8
wherein bearing housing
27
is shown in cutaway, with the balance of the view as an elevational view, to permit viewing of the bearing
28
therein. Note that only two of the radii of both the upper radii,
24
A and
24
E and the
23
A and
23
E of the lower base are shown in FIG.
8
. Both center plates
26
, namely
26
B and
26
T as shown in
FIG. 1
are shown here as well.
In
FIG. 8
, lower base radii are seen spaced slightly apart, but in a welded position to the lower base plate
25
. Disposed on the upper surface thereof,
25
T is a cylindrical tube
30
of an elevation that can vary as may be desired, but with an elevation of four [4] inches providing good results. This tube
30
is welded or otherwise attached to the bearing housing
27
at its upper end and the top surface
25
T of the lower base plate on its lower end. The housing is a cup-like segment having an acute side wall, and a flat bottom and is open at the top.
Disposed within the bearing housing
27
are a pair of hubs
33
disposed over a smaller hub
33
′, each having a plurality of ball bearings
34
therein. Such multi bearing hubs are well known in the art and are found in moving casters. The balls of the larger upper rotate against the surface of an optional galvanized cover plate
42
, while the lower set of bearings rotate on the interior bottom wall of the housing
27
.
A bolt or rivet holds the two hubs together for rotation relative to each other.
Cover plate
42
is welded or otherwise attached on one face to the bearing housing to close it off, and is attached in like manner on its other face to the upper base's bottom plate
26
B.
It can be seen that the bottom plate
26
B may also be employed directly to seal off the bearing housing, if so desired.
As can be seen here in
FIG. 8
, a sandwich is formed between the two top plates
25
T and
25
B with the series of radii welded between them. The slight space shown between radii
24
A and
24
E, allows for adequate heat expansion.
FIG. 10
is a perspective view showing a conventional coil
60
of drip tubing disposed upon the reel
13
and resting upon the upper base
11
. Only lower base
11
is partially visible.
In
FIG. 11
an alternate configuration for the device is seen and designated
100
. In this alternate version, there is a lower base
111
that is round instead of octagonal and an upper base
112
that is also round. Optional carry handles
43
spaced 180 degrees apart are seen. All other elements are the same as in FIG.
1
and need not be discussed further.
In
FIG. 12
an optional counter mechanism of a conventional construction is shown, and is designated
50
. The counter
50
includes a housing
51
which can be attached as by welding to device
10
. The counter mechanism includes a pair of spaced rollers
52
at least on which is mechanically connected to a gear system not seen, which gear system is also connected to digital read out
53
. As the tubing
60
is pulled through the two spaced rollers, the tubing frictionally engages the rollers such that they rotate to thereby move the gear connected counter readout to tell how much tubing has moved through the rollers. Such counter mechanisms are well known for the measurement of wire.
It is seen that I have devised a horizontally oriented dispenser for drip line tubing. This horizontal dispenser has a reel that holds a coil of drip tubing and which coil is easily placed on and off such a reel. By providing grab bars on the upper base, the unit can be easily loaded and unloaded from a vehicle, as needed, even by one person.
While the reels contemplated for this device are intended to be sized for a specific length of tubing such as 500 or 1,000 feet linearly, for commercial purposes, it is also within the scope of the invention to employ interchangeable replaceable reels each sized to accommodate a specific length of coil of tubing.
Reference is thus made to
FIG. 13
which depicts such a construction diagrammaticaly Here reel member
31
A,—the only one partially shown since all reel member
31
A-H would be mounted in like manner,—is instead of being welded in place is merely bolted into its location. Here, a pair of spaced L flanges
45
that are positioned in an opposed spaced position, with the spacing just equal to the size of the square tubing employed in the reel are disposed upon the top surface of each upper base radius such as
24
A. Each flange member has a bolt hole
46
for receiving bolt
47
when such bolt is placed through bolt hole
46
in the flange
45
and through bolt hole
49
in the respective reel arm. Bolt
47
is retained by the tightening of nut
48
.
Rotation of the handle
37
allows a large amount of tubing to be dispensed quickly, and if necessary to be wound back should excess have been unwound over the amount needed.
The end of the tubing coil
60
can also be tied on to a grab bar to ensure maintenance of the coil during periods of transportation both in the field and in a vehicle.
Thus the upper base rotates relative to the lower base due to the presence of the bearing in the bearing housing. A person pulls on the end of the coil
60
of drip line to dispense the needed, amount. The larger lower base stays in place as the drip line uncoils.
To rewind, just counter-rotate the handle.
While the device of this invention is made of steel and/or other metals, and is assembled by welding or brazing, no reason is seen why this device cannot be made of a strong plastic just as easily, or even a combination of plastic and metal.
The grab bars may have a rubber coating or a rubber overlay thereon, as may the handle for more convenient use in cold weather.
It is also to be seen that while the intent of this invention is to serve as an device to dispense drip irrigation line, there may be instances where extremely long lengths of garden hose need be dispensed as well. No reason is seen why this device would not serve that purpose as well.
Since certain charges may be made in the above apparatus without departing from the scope of the invention herein involved, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
