FIELD OF THE INVENTION
The present invention relates in general to the field of water pumps, and more specifically, to an attachment for a water pump configured to connect to the rear wheel of a motorcycle or motorscooter to provide power to the water pump and a method of pumping water using the attachment. The purpose of the invention is to provide an attachment and method that may utilize existing motorized vehicles prevalent in developing countries (e.g., motorcycles, motorscooters) to provide energy to the water pump for conveying water. Thus, water may be delivered in developing countries that often lack the basic resources necessary to power a water pump, such as electricity or a petrol generator. An additional purpose of the invention is to provide a rugged device that is cost-efficient to manufacture, inexpensive to purchase, easy to operate and convenient to store.
BACKGROUND OF THE INVENTION
Clean, accessible water is vital to human health. Unfortunately, over 40% of the global population does not have access to clean water. According to the United Nations, about 4 billion people, representing nearly two-thirds of the world population, experience severe water scarcity during at least one month of the year. Water Scarcity, UN-Water (July, 2019), available at https://www.unwater.org/water-facts/scarcity/. Developing countries are most affected by water shortages and poor water quality. Indeed, the Global Water Institute has determined that in developing countries the lack of clean water and sanitation are the source of health problems for almost half of the population and can be linked to 80% of disease. Elizabeth Hameeteman, Future Water (IN)Security: Facts, Figures, and Predictions, Global Water Institute (2013).
In many of these developing countries, particularly in rural areas, households don't have accessibility to electricity or the resources needed to purchase and maintain petrol generators for operating a water pump. Despite this fact, the number of private vehicles—namely motorcycles and motorscooters—is increasing in almost all developing countries. For example close to 80% of households in Delhi, India have motor vehicles, most of them two-wheelers. The reason for this astonishing figure is that motorcycles and motorscooters may cost as little as $200 in developing countries. At such low costs families no longer have to accumulate considerable savings to own a vehicle. Indeed, motorcycles and motorscooters are the lifeblood of millions of individuals and small businesses in developing countries, transporting families, farm products and locally manufactured goods on a daily basis.
Thus, a desire remains to provide access to water in developing countries where electricity and petrol generators are scarce or cost-prohibitive. A desire also remains to use existing motorized devices common in such developing countries, such as motorcycles or motorscooters, as a power source for delivering water in a convenient and cost-efficient manner.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 illustrates an isometric front-top-right side view of one aspect of the aquacycle pump (10) of the present disclosure. In particular, the aquacycle pump (10) comprises a base plate (12) configured to be placed on the ground and other hard, flat surfaces. The base plate (12) may include a first side wall (14) and an opposite, second side wall (16). The first side wall (14) may have a series of openings (18) along a top portion of the first side wall (14). The second side wall (16) may also have a series of openings (20) along a top portion of the second side wall (16). The series of openings (18) of the first side wall (14) are configured to correspond to the series of openings (20) of the second side wall (16). The base plate (12) and first and second side walls (14, 16) may be integrally formed together during the manufacturing process, or alternatively, the base plate (12) and first and second side walls (14, 16) may be formed separately during the manufacturing process and then permanently or removably fixed together using welds, glues, screws, bolts, rivets, or other common means of attachment. It is contemplated that base plate (12) and first and second side walls (14, 16) of the aquacycle pump (10) may be comprised of steel, stainless steel, plastics, aluminum or combinations thereof.
Shown in FIG. 1, the first and second side walls (14, 16) of the base plate (12) may include a support bracket (22). The support bracket (22) may be formed integrally with the first and second side walls (14, 16) of the base plate (12). Thus, the support bracket (22) may also be comprised of steel, stainless steel, plastics, aluminum or combinations thereof.
FIG. 2 illustrates the aquacycle pump (10) connected to a motorcycle or motorscooter (24). In particular, FIGS. 1-2 show that the support bracket (22) of the aquacycle pump (10) is configured to support a roller (26). The roller (26) is configured to be in contact a rear wheel of the motorcycle or motorscooter (24). In particular, the roller (26) may comprise an inner shaft (28) and an outer coating (30). The inner shaft (28) may be comprised of steel, stainless steel, plastics, aluminum or combinations thereof. The outer coating (30) may be a rubberized coating around the shaft (28), wherein the outer coating (30) is configured to be in contact with, abut against, and improve traction with a tire of the rear wheel of the motorcycle or motorscooter (24). The inner shaft (28) and the outer coating (30) may be permanently or removably adhered or affixed together, wherein the inner shaft (28) is configured to not move, slide, or rotate inside the outer coating (30). Therefore the inner shaft (28) and the outer coating (30) are configured to act and rotate together as a single unit.
FIG. 3 illustrates an isometric top view of the aquacycle pump (10). In particular, FIGS. 1-3 show that the support bracket (22) may include holes configured such that the inner shaft (28) of the roller (26) traverses therethrough and rotates freely therein. The support bracket (22) may further comprise bearings to assist the inner shaft (28) in rotating freely in the holes of the support bracket (22), The roller (26) is configured such that as the rear Wheel of the motorcycle or motorscooter (24) rotates and is in contact with the adjacent outer coating (30) of the roller (26), the traction between the rear wheel and the outer coating (30) also causes the outer coating (30) to rotate. The rotation of the outer coating (30), in turn, further causes the inner shaft (28) to rotate freely in the support bracket (22) The outer coating (30) and the inner shaft (28) therefore are configured to act and rotate together as a single unit.
FIG. 4 illustrates an isometric rear view of the aquacycle pump (10). In particular, FIGS. 1-4 show that the aquacycle pump (10) may comprise a water pump support plate (32) and a water pump (34). The water pump support plate (32) may be configured to support the water pump (34) in a fixed position. In particular, the water pump support plate (32) may be integrally formed with the base plate (12) and/or the first or second side walls (14, 16) as one piece, or alternatively, the water pump support plate (32) may be permanently or removably attached to the base plate (12) and/or either the first or second side walls (14, 16) using welds, glues, screws, bolts, rivets, or other common means of attachment. It is contemplated that the water pump support plate (32) of the aquacycle pump (10) may be comprised of steel, stainless steel, plastics, aluminum or combinations thereof.
Further shown in FIGS. 1-4, the water pump (34) may comprise a centrifugal water pump or a positive displacement water pump (e.g., diaphragm, gear, lobe, peristaltic, or piston pinup). The water pump (34) may be removably attached to the water pump support plate (32) using screws, bolts, rivets, or other common means of removable attachment for an event Where the water pump (34) may need to be removed from the water pump support plate (32), repaired and/or replaced. The water pump (34) may include an inlet opening (36) for attaching an inlet hose and an outlet opening (38) for attaching an outlet hose for pumping and transferring water through the water pump (34), The water pump (34) may further comprise a water pump shaft (40) for operating the water pump (34).
Still farther shown in FIGS. 1-4, the water pump shaft (34) may be removably coupled to the inner shaft (42) of the roller (26) via a shaft coupler (42). For exemplary purposes only, the shaft coupler (42) may be a circular, hollow tube comprised of steel, stainless steel, plastics, aluminum or combinations thereof. It is contemplated that hollow tubes comprised of other tubular shapes (e.g., square, pentagon, hexagon, octagon, etc.) and materials may also be utilized. The shaft coupler (42) may further comprise at least two threaded holes traversing through a side wall of the hollow tube, and a corresponding screw or bolt configured to be inserted into and screwed through each threaded hole. The shaft coupler (42) may removably couple the water pump shaft (34) to the inner shaft (28) of the roller (26) by inserting a free end of the water pump shaft (34) into, an open end of the hollow tube and screwing a screw or bolt inside the threaded hole to press against the free end of the water pump shaft (34) in the hollow tube to effectively lock the free end of the water pump shaft (34) in the shaft coupler (42). Similarly, a free end of the inner shaft (42) of the roller (26) may be inserted into the remaining open end of the hollow tube, wherein a screw or bolt is screwed inside the threaded hole to press against the free end of the of the inner shaft (42) in the hollow tube to effectively lock the free end of the of the inner shaft (42) in the shaft coupler (42). It is to be understood that shaft coupler (42) described above is merely illustrative and are not intended to confine the scope of the present disclosure, as it is intended that other means of removably coupling the water pump shaft (34) to the inner shaft (42) of the roller (26) may also be utilized, such as via screws, bobs, interlocking joints, threaded pieces, or other means of removable coupling. As the wheel of the motorcycle or motorscooter (24) in contact with the roller (26) rotates, this in turn causes the roller (26) to rotate the inner shaft (28) and the water pump shaft (40) coupled together via the shaft coupler (42). The rotating water pump shaft (40) operates the water pump (34) of the aquacycle pump (10) to convey the water to the location where water is needed.
FIGS. 5 and 6 illustrate isometric right and left side views, respectively, of the aquacycle pump (10). In particular, FIG. 5 shows the series of openings (18) along the top portion of the first side wall (14). FIG. 5 further shows the water pump (34) in a fixed position on top of the water pump support plate (32). FIG. 6 shows the series of openings (20) along the top portion of the second side wall (16). FIG. 6 further shows the support bracket (22) supporting the inner shaft (28) of the roller (26), wherein the support bracket (22) includes bearings to assist the inner shaft (28) in rotating freely in the hole of the support bracket (22).
FIGS. 7 and 8 illustrate isometric front-top-left side views of the aquacycle pump (10) in a retracted position and an expanded position, respectively. In particular, FIGS. 1-3, 7-8 show that the aquacycle pump (10) may further comprise a kick-stand support bracket (44). The kick-stand support bracket (44) is configured to secure the aquacycle pump (10) in position, to constrict movement of the aquacycle pump (10) during operation, and to help maintain the roller (26) in contact with the rear wheel of the motorcycle or motorscooter (24).
Shown in FIGS. 7 and 8, the kick-stand support bracket (44) may include a base bracket (46), a first side bracket (48), an opposite second side bracket (50), and a kick-stand holder (52). The first side bracket (48) may have a series of openings (54) along a top portion of the first side bracket (48). The second side bracket (50) may also have a series of openings (56) along a top portion of the second side bracket (50). The series of openings (54) of the first side bracket (48) are configured to correspond to the series of openings (56) of the second side bracket (50). The kick-stand holder (52) may comprise a hole through the base bracket (46), wherein the hole may be surrounded by a physical barrier (e.g., wall, fence, barricade, block, lip, bump-out, ridge, partition, etc.) configured to constrict movement of the aquacycle pump (10) during operation and to help maintain the roller (26) in contact with the rear wheel of the motorcycle or motorscooter (24). In particular, the roller (26) may be pressed against the rear wheel of the motorcycle or motorscooter (24), wherein the outer coating (30) is in contact with the tire. In this position, the kickstand of the motorcycle or motorscooter (24) abuts a front barrier of the kick-stand holder (52), wherein the kickstand is solidly engaged with the ground under the weight of the motorcycle or motorscooter (24). The kickstand when engaged with the ground is configured to not move forward (i.e., towards the front wheel of the motorcycle or motorscooter), only backwards, because of the configuration of the kickstand. The kickstand when engaged with the ground therefore serves as a solid fixture for which the kick-stand holder (52) of the aquacycle pump (10) may abut against to help constrict movement of the aquacycle pump (10) during operation and to help maintain contact between the roller (26) and the rear wheel of the motorcycle or motorscooter (24). The kick-stand holder (52) may also be configured to maintain the motorcycle or motorscooter (24) in a set position after the engine is started, shifted into gear, and throttled to provide power to rotate the rear wheel. The base bracket (46), first and second side brackets (48, 50), and kick-stand holder (52) may be integrally formed together during the manufacturing process, or alternatively, the base bracket (46), first and second side brackets (48, 50), and kick-stand holder (52) may be formed separately during the manufacturing process and then permanently or removably fixed together using welds, glues, screws, bolts, rivets, or other common means of attachment. It is contemplated that base bracket (46), first and second side brackets (48, 50), and kick-stand holder (52) of the aquacycle pump (10) may be comprised of steel, stainless steel, plastics, aluminum or combinations thereof.
Shown in FIGS. 1-3, 7-8, the kick-stand support bracket (44) may be configured to slide on top of the base plate (12) to adjust the aquacycle pump (10) into a retracted position (58) or an expanded position (60), or anywhere in between. In particular, the aquacycle pump (10) may be extended in overall length from approximately 18 centimeters in the retracted position (58) to approximately 45 centimeters in the expanded position (60). The retracted position (58) of the aquacycle pump (10) may be utilized for smaller motorcycles or motorscooters of a shorter overall length. The expanded position (60) of the aquacycle pump (10) may be utilized for larger motorcycles or motorscooters of a longer overall length. The aquacycle pump (10) may be locked (or unlocked) in either the retracted position (58) or the expanded position (60), or anywhere in between, using at least one locking mechanism (62) and the series of openings (18, 20) of the first and second side walls (14, 16) and the series of openings (54, 56) of the first and second side brackets (48, 50). In particular, the series of openings (54) of the first side bracket (48) may be configured to align with the series of openings (18) of the first side wall (14). The series of openings (56) of the second side bracket (50) may also be configured to align with the series of openings (20) of the second side wall (16). The locking mechanism (62) may be utilized to fit into the aligned openings (54, 18) of the first side bracket (48) and first side wall (14). Another locking mechanism (62) may be utilized to fit into the aligned openings (56, 20) of the second side bracket (50) and the second side wall (16). The locking mechanism (62), such as a bolt, screw, clamp, or pin, is configured to effectively lock (and unlock) the kick-stand support bracket (44) in the retracted position (58) or the expanded position (60) for the aquacycle pump (10). Thus, a user may adjust the length of the first and side brackets (48, 50) to engage the roller (26) with the rear wheel of the motorcycle or motorscooter (24) and then lock the first and second side brackets (48, 50) into position using the locking mechanism (62). The kickstand of the motorcycle or motorscooter (24) when engaged with the ground therefore prevents the kick-stand support bracket (44) from moving forward away from the rear wheel of the motorcycle or motorscooter (24) to constrict movement of the aquacycle pump (10) during operation, and to also help maintain contact between the roller (26) and the rear wheel.
Another aspect of the present disclosure is a method of pumping water using the aquacycle pump of FIGS. 1-8. In particular, the method may comprise providing a source of water (e.g., well, reservoir, storage tank, river, lake, etc.) that needs to be conveyed to another location. The method may include providing a motorcycle or motorscooter (24), wherein the motorcycle or motorscooter's (24) ignition is turned off. The motorcycle or motorscooter (24) may include a kick-stand and a rear wheel, wherein the motorcycle or motorscooter (24) is rear-wheel drive. The method may further comprise providing the aquacycle pump (10) of FIGS. 1-8. Depending on the size of the motorcycle or motorscooter (24), the kick-stand support bracket (44) of the aquacycle pump (10) may be adjusted in length and locked into the retracted position (58) or the expanded position (60), or anywhere in between, using the aligned series of openings (18, 20, 54, 56) and the at least one locking mechanism (62) so that the aquacycle pump (10) is compatible in length with the motorcycle or motorscooter. The kick-stand may be set in the kick stand holder (52) to secure the aquacycle pump (10) in position, to constrict movement of the aquacycle pump (10) during operation, and to help maintain contact between the roller (26) and the rear wheel of the motorcycle or motorscooter (24).
The method may comprise placing a rear wheel of the motorcycle or motorscooter (24) in contact with the roller (26) of the aquacycle pump (10). In particular, the tire of the rear wheel of the motorcycle or motorscooter (24) is placed adjacent to and abutting against the outer coating (30) of the roller (26), wherein the tire is effectively resting on top of the roller (26). The method may also include placing one end of the inlet hose into the water source and connecting the other end of the inlet hose to the inlet opening (36) of the water pump (34). One end of the outlet hose may then be connected to the outlet opening (38) of the water pump (34) and the other end of the outlet hose placed at a location where the water is needed, such as to a crop field for irrigation, to a household or business for personal water use, or to a livestock water trough in a pen or pasture. It is contemplated that other locations that need water may also be benefited by the aquacycle pump (10) and method of use of the present disclosure, in addition to the illustrative examples set forth above.
The method may further comprise starting the engine of the motorcycle or motorscooter (24), shifting it into gear, and throttling the engine to provide power to rotate the rear wheel of the motorcycle or motorscooter (24). As the rear wheel rotates, traction between the rear wheel and the outer coating (30) also causes the roller (26) of the aquacycle pump (10) to rotate in unison. The rotating roller (26), in turn, rotates the inner shaft (28) and the water pump shaft (40) coupled together via the shaft coupler (42). The rotating water pump shaft (40) operates the water pump (34) of the aquacycle pump (10) to convey the water to the location where water is needed through the inlet and outlet hoses. For example, with a throttle of the motorcycle or motorscooter (24) set at 1,200 revolutions per minute (“RPM”), the aquacycle pump (10) may transfer approximately 83 liters per minute or 4,980 liters per hour. The method may next include making a determination that enough water has been conveyed by the aquacycle pump (10) to the location where water was needed. After such a determination is made, the method may comprise shifting the motorcycle or motorscooter (24) out of gear and/or turning off the ignition to stop the rear tire from rotating. Once the rear tire stops rotating, consequently, the roller (26) of the aquacycle pump (10) also stops rotating which halts the operation of the water pump (34) and the conveyance of water. The motorcycle or motorscooter (24) may then be removed from the aquacycle pump (10) and used separately for transportation purposes, wherein the aquacycle pump (10) may be conveniently stored until a future conveyance of water is needed.
The aquacycle pump (10) of the present disclosure and method of pumping water using the aquacycle pump (10) are universally applicable to motorcycles and motorscooters (24) of all shapes and sizes, makes, models, and manufacturers. Furthermore, while intended for conveying water, the aquacycle pump (10) and method of pumping water using the aquacycle pump (10) may be used for all types of liquids or fluids commonly conveyed by centrifugal or positive displacement pumps. Although the disclosure has been described and illustrated with respect to preferred aspects thereof, it is not to be so limited since changes and modifications may be made therein which are within the full intended scope of the disclosure.
