- the belt transport system selectively engages balls that enter through an opening in the front panel.
- the balls are urged along the ball collecting surface and engage a ball scoop 300 which transitions the balls from a horizontal plane to a vertical plane. After the balls are transitioned in into the vertical plane, they are held by ball transport members 400 spaced along the outer edge of the belt 208 .
- the belt 208 includes an inner surface with a plurality of ridges 228 that engage a plurality of teeth 232 on the pulleys 236 which transmit rotational motion of the pulleys to lateral motion of the of the belt.
- the belt 208 is moved which moves the balls upwardly towards the upper pulley 200 . After the balls reach the apex of the upper pulley 200 , gravity will cause them to disassociate with the ball transport member 400 and fall into the basket.
- FIG. 11 is a detailed view showing how one or more balls 500 are initially engaged by the belt 208 .
- An upper surface 404 of the ball transport members engages an outer surface of the ball 50 .
- Further movement of the ball collecting apparatus rotates the lower pulley 204 , which will incrementally move the belt 208 by way of interaction of teeth 232 on the pulley and ridges 228 on the belt.
- the balls 500 will eventually come in contact with a ball scoop (not shown) which helps transition the balls 500 from the horizontal plane to the vertical plane.
- the ball transport members 400 can be spaced such that they closely match the diameter of the ball 500 being collected, which further helps keep the balls 500 onto the upper surface 404 of the ball transport members.
- FIGS. 12 and 13 show ball transport members of one embodiment of the present invention.
- the upper surface 404 of the ball left segment employs a curve upper profile which terminates at a curled end 408 .
- the curved profile helps scoop the balls from the ball collecting surface and to maintain them on the upper surface 404 as they are transitioned from horizontal plane to the vertical plane.
- the ball transport members may include a plurality of stiffening ribs 408 to provide additional rigidity while reducing weight.
- the ball transport members also include a longitudinal channel 412 or pocket, or series of pockets that extend at least partially the width thereof.
- the channel 412 is adapted to selectively receive a portion of a belt segment as described below.
- the ball transport members may also include upper and lower feet 416 that engage the outer surface of the belt, which helps increase stability of the ball transport members relative to the belt segment. Stated differently, the feet 416 help prevent relative motion of the ball transport members relative to the belt transport members and provides a rigid, generally 90° interconnection between the ball transport members and the belt.
- FIG. 14 shows a belt segment 240 of one embodiment of the present invention.
- the ball transport members are selectively interconnected to the belt 208 that generally spans the entire height of the ball collecting apparatus.
- the belt 208 of one embodiment of the present invention is made from a plurality of segments 240 interconnected to each other by the ball transport members.
- the belt segments 240 include a generally smooth outer surface and an inner surface with ridges 228 that selectively engage corresponding teeth on the lower and upper pulleys.
- the belt segment 240 may also include an upper and lower tab 244 that extend from the outer surface of the belt segment 240 .
- the tabs of belt segments 240 are selectively engaged and held together when placed within the channel ( 412 , See FIGS. 12 and 13 ) provided by the ball transport members.
- Fasteners can interconnect the ball transport members to the belt segments 240 wherein the fasteners are placed through the upper or lower surfaces of the transport members and maintained by a nut or other fastening device associated with the opposite side of the ball transport members. In this way, the upper and lower edges of the belt segments 240 are sandwiched together and maintain within the channel of the ball transport members.
- the tab 244 associated with the belt segments 244 need not extend the entire width thereof and smaller tabs may be employed. If belt segments 240 become worn or damaged, they can be easily replaced by removing the fasteners associated with the ball transport members.
- FIG. 15 shows the pulley of one embodiment of the present invention.
- the pulleys may comprise two pulley wheels (See FIG. 11 ) as shown in FIG. 15 .

- FIG. 16 shows a belt comprising a plurality of belt segments maintained by the ball transport members. Again, the tabs 244 associated with adjacent belt segments 240 are placed within the cavity provided by the ball transport members. The tabs 244 may be maintained within the channels 412 by any common method, such as gluing, welding, ultrasonic welding, fasteners, etc. However, fastening allows for a selective interconnection scheme wherein ball transport members can be selectively removed and replaced if needed. FIG. 16 also shows the interplay between the teeth 232 provided by the lower pulley 204 and the ridges 228 provided by the inner surface of each belt segment 240 .
- FIG. 16 also shows the ball scoop 300 associated with one embodiment of the present invention, which is also shown in detail in FIG. 17 .
- the ball scoop 300 helps transition collected balls being urged rearwardly by ball transport systems from the horizontal plane to the vertical plane. The balls contact a leading edge 304 of the ball scoop 300 and ride on the ball scoop 300 and are eventually positioned on the upper surface of the ball transport systems. The ball transport systems will then raise the balls upwardly as described above. Because it is often important to maintain a close tolerance between the leading edge 304 and the collecting surface so balls do not jam between the ball scoop 300 and the collection surface, one embodiment of the present invention employs a leading-edge roller 308 that facilitates interaction between the balls so they easily move along the ball scoop. The leading-edge roller 308 also may contact the collecting surface to eliminate any gap between the leading-edge 304 and the ball collecting surface.

Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/310,008, filed Mar. 18, 2016, and U.S. Provisional Patent Application Ser. No. 62/425,542, filed Nov. 22, 2016, the entire disclosures of which are incorporated by reference herein.
- Embodiments of the present invention are generally related to an apparatus that gathers balls and moves them to an easy-to-access location, thereby eliminating the need to manually transfer balls from one basket to another.
- Tennis is a very popular game world-wide. Indeed, many tennis novices take lessons to increase their proficiency. Lessons comprise practicing skills necessary to perform at a higher level and often entail the student hitting many tennis balls against the wall or returning them to instructor or fellow students across the net. Two common pieces of equipment assist instructors and players.
- The first piece of equipment is an instructor teaching cart, which can hold approximately 350 tennis balls at waist level. During a lesson, an instructor or student repeatedly reaches into the teaching cart to access balls. Traditional teaching carts can move longitudinally and laterally on four wheels, which allows instructor or player to easily maneuver the cart to different areas of the tennis court.
- The second piece of equipment is a tennis ball mower that retrieves a plurality of balls from the court that are later moved to the teaching cart, ball machine, or smaller ball baskets. The alternative to using a mower is to hand-pick each ball from the tennis court. Tennis ball mowers are usually large and bulky, and take up valuable space on the tennis court. The traditional tennis ball mowers collect the balls in a basket at ground level, requiring someone to manually transfer the basket of balls into another storage area. This task is inefficient and awkward.
- The following describes a tennis ball collecting apparatus that does not rely on an outside power source, that is very maneuverable, and that efficiently collects the balls and sends them automatically upwards to a waist-level storage basket, thereby offering easy access to the balls without manual transferring the balls.
- It is one aspect of embodiments of the present invention to provide a ball collecting apparatus that has the functionality of the ball mower and a ball delivery device, commonly known as an instructor ball cart. The apparatus contemplated by some embodiments of the present invention collects tennis balls and moves them from the ground to a second position above the ground, which makes the balls easy to access without the user having to bend over. In addition, unlike ball mowers of the prior art, the ball collecting apparatus of one embodiment does not rely on motorized devices for propulsion or to transfer collected balls from the ground to a storage location. Although this disclosure concentrates primarily on tennis balls, one of ordinary skill the art will appreciate the ball collecting apparatus and components thereof described herein can be modified to collect any type of ball, such as golf balls, basketballs, baseballs, softballs, ping-pong balls, etc., without departing from the scope of the invention.
- It is another aspect of embodiments of the present invention to provide a ball collecting apparatus that can move longitudinally and laterally. More specifically, after the balls are moved to the elevated storage position, it is desirous to be able to move the apparatus longitudinally (i.e., forward and backward) and laterally (i.e., side to side). This mobility allows the instructor or tennis player to quickly move the apparatus to a desired location on the tennis court.
- It is yet another aspect of embodiments of the present invention to provide a ball collecting apparatus that relies solely on human power to operate. The absence of batteries, motors, and other complex machinery, allows the ball collecting device to be light, which enhances maneuverability. Additionally, the absence of an outside power source is more efficient as there is no need to charge any batteries or connect to a power source. The ball collecting apparatus can operate indoors and outdoors without requiring a power source or an electrical cord, which may present a dangerous obstacle on the tennis court. The ball collecting device of one embodiment employs a plurality of wheels that allow to be easily moved along a given area. Forward movement activates a ball transport system that engages at least one ball, moves the ball into the apparatus, and lifts the ball into the storage location. For example, the storage location may be a basket positioned above the ground that is more accessible to the user. An integrated ball storage location also avoids having to manually transfer/empty the collected balls into a second instructor cart. Conversely, current methods include collecting balls at ground level with tennis ball mowers, hand-held baskets, collection tubes, etc. and thereafter manually transferring the collected balls to other equipment, such as tennis ball instructor carts, where they are used for instruction and practice.
- It is a related aspect of some embodiments of the present invention to provide a removable basket that receives collected tennis balls. The removable basket may be used interconnected to the ball collecting apparatus, wherein the balls are collected and deposited in the basket at an elevated level. In this mode of use, the ball collecting apparatus doubles as an instructional cart. In a second mode of use, the basket is removed and moved to a different location on the court.
- The basket of one embodiment of the present invention includes handles. The handles may be rotated relative to each other such that the upper portions normally used for carrying the basket are transformed into feet that are placed on the playing surface. The length of the handles will dictate the elevation of the basket when the handles are rotated into their second position of use. Ideally, handles are elongated such that the basket is positioned at or near waist level. The handles may telescope such that when used in the first mode of use (i.e., ball collecting), they are shorter than when they are in the second mode of use (i.e., practice configuration). Some ball collecting devices employ multiple locations for storing more than one basket; once a first basket is full, it is replaced with an empty basket. In this example, both baskets can be interconnected to the ball collecting device.
- Some embodiments of the present invention comprise a housing having a left panel, right panel, a front panel, and a rear panel that envelope the ball transport system. The front panel has a bottom opening configured to receive at least one ball, and an upper opening associated with the ball storage location, e.g., the basket. In operation, the ball transport system moves balls received in the lower opening to the upper opening. Some embodiments of the present invention include arms adjacent to lateral edges of the lower opening that help corral the balls into the lower opening. The arms may be fixed to the left and right panels or selectively interconnected thereto to facilitate storage. In some other versions, the arms are selectively deployable and capable of moving so they do not adversely affect mobility during instruction.
- The ball transport system of one embodiment of the present invention employs upper and lower pulleys that operatively interconnect to a belt. The lower pulley is also operatively interconnected to primary wheels that support the ball collecting apparatus. The lower pulley rotates as the wheels rotate forward. That is, movement of the ball collecting apparatus in the forward direction moves a portion of the belt from a location near the bottom opening of the front panel to a location near the upper opening of the front panel. Movement of the wheels in the opposite direction, however, will not rotate the lower pulley so the belt can only move one way. The rear panel may be removable to address ball jam issues if necessary. The belt also accommodates a plurality of ball transport members that engage balls and help transport them to the upper opening of the front panel. In one embodiment of the present invention, the belt is made from a plurality of segments, which will be further discussed below.
- It is another aspect of some embodiments of the present invention to provide a ball collecting apparatus that is durable, weatherproof, and which includes built-in ergonomic features. For example, some embodiments employ a recess in an upper portion thereof adapted to receive a water bottle or cell phone. In addition, the upper portion may be configured to receive a tablet computer or a chalkboard. In addition, a dry erase board may be included on the upper portion to be used for instruction along with magnets or dry erase markers, for example.

FIGS. 1-17 show a ball collecting apparatus 2 of one embodiment of the present invention and components thereof. More specifically,FIGS. 1-5 show a ball collecting apparatus comprising a right panel 6, leftpanel 10, afront panel 14 and arear panel 18. The right panel 6 and leftpanel 10 include extensions 22 (also referred to as “arms”) that direct balls into alower opening 26 of thefront panel 14 as the ball collecting apparatus 2 is moved forward. The ball collecting apparatus 2 also includes aleft wheel 30 and aright wheel 34 that maintain a space between an underside portion of the ball collecting apparatus 2 and a collection surface, e.g., a tennis court. The ball collecting apparatus 2 employs aball transport system 38 that is operably interconnected to the left or right wheel assembly such that when the left or right wheel is are rotated, thetransport system 38 moves in such a way to transport balls from the ball collection surface through anupper opening 42 provided in thefront panel 14. - In operation, the user grasps a
handle 46 associated with anupper tray 50 of the ball collecting apparatus 2 and pushes forward. Propulsion is provided by human energy, facilitated by the left or right wheels provided on each side of the ball collecting apparatus. Theextensions 22 are supported bycaster rollers 54 at their distal ends. Accordingly, the ball collecting apparatus 2 is supported by wheels adapted to move in gently one direction (forward and backward), and to rollers adapted to move in multiple directions that allow the apparatus to be stable and maneuverable. - In operation, the user moves the ball collecting apparatus 2 forward towards one or more balls on a surface. Moving the ball collecting apparatus 2 forward causes the
left wheel 30 andright wheel 34 to rotate, which imparts a rotation on internal componentry that moves theball transport system 38. Balls gathered by theextensions 22 are channeled towards thelower opening 26 of thefront panel 14, selectively captured by the transport system, moved to theupper opening 42 of the front panel, and are deposit in a ball storage location, e.g., a basket. - The ball collecting apparatus of one embodiment of the present invention is approximately 40 inches tall, by 22.5 inches wide. The distance between the
handle 46, approximately the extreme rear of the ball collecting apparatus, and the tips of theextensions 22 in one embodiment of the present invention is about 37.5 inches. Further, the ball collecting apparatus of one embodiment of the present invention weighs about 130 pounds and, thus, is easy to maneuver. The decreased weight savings is achieved by omitting the use of heavy motors or other drive devices. Furthermore, components of one embodiment of the present invention are made of lightweight materials such as linear low-density polyethylene (LLDPE). - One of ordinary skill the art will appreciate that the dimensions of the ball collecting apparatus disclosed herein may be selectively altered to fit the collection needs. For example, the wheels of a baseball collecting apparatus may need to be altered to accommodate grass or AstroTurf which are rougher than a tennis court. Furthermore, for some collection scenarios a motor may be needed to help the use to propel the apparatus across a bumpy or inconsistent terrain.

FIGS. 6-8 show one embodiment of the present invention having a selectivelyinterconnected basket 58 that receives collected balls. The ball collecting apparatus includes abasket support rod 62 that extends from theleft panel 10 to the right panel 6. Thebasket support rod 62 generally corresponds with a lower edge 66 of theupper opening 42 of the front panel and is contoured to selectively receive thebasket 58. One of ordinary skill in the art will appreciate thebasket 58 may be configured such that it engages the lower edge 66 without departing from the scope of the invention. Other embodiments provide small protrusions extending from inner surfaces of the left and right panels that receive corresponding hook members of the basket. As shown, thebasket 58 includes at least oneupper edge 70 defined by the basket's four sides. At least a portion of theupper edge 70 includes a hookedlip 74. In practice, the hookedlip 74 is selectively engaged onto thebasket support rod 62 to maintain the position of thebasket 58 on the ball collecting apparatus 2. In operation, as the ball collecting operation apparatus 2 is moved, balls are transported from the collecting surface through theupper opening 42 in thefront panel 14. Thebasket 58 captures balls as they are ejected from the apparatus. -
FIG. 8 provides a cross-sectional view of the ball collecting apparatus 2 of one embodiment of the present invention that shows how thebasket 58 is interconnected to thebasket support rod 62. This figure also shows thelower opening 26 of thefront panel 14 and how theextensions 22 are configured to channel one or more balls into thelower opening 26. After the balls enter thelower opening 26, the moving ball transport system, which is moved by the rotating wheels, grabs the balls, and moves them incrementally upwardly towards theupper opening 42. As will be further explained below, balls are maintained in ball transport members and therear panel 18. After balls reach the apex of the ball collecting apparatus, they are moved around an upper pulley and ejected out of theupper opening 42 into thebasket 58. - After the balls are collected, the
basket 58 may be removed from the ball collecting apparatus 2 and moved to a second location. As it may be desirable to position the balls closer to the tennis player's waist, one embodiment of the present invention provides abasket 58 with selectively alterable handles.FIG. 7 shows thebasket 58 in a second configuration wherein afirst handle 86 in the second handle 40 have been rotated abouthubs 94 on the sides of thebasket 58. After the first and second handles are rotated into a second position, they are locked in place bylower locks 98, thereby forming afirst leg 102 and asecond leg 106 that support thebasket 58. Thebasket 58 may also includeupper locks 110 that maintain the first and second handles in the configuration shown inFIG. 6 . Thebasket 58 may incorporate integrated legs that may be of fixed length or have a length that is selectively alterable such that the distance between the lower portion of the basket and the end of the legs may be selectively altered to fit the player's needs. For example, telescoping legs may be provided that are concealed within the basket when not in use. One of ordinary skill of the art should appreciate that the handles/legs provided inFIGS. 6 and 7 are not limiting, and many ways of supporting the basket at a height above the collecting service may be provided. Those of skill in the art should also appreciate that a removable basket may not be employed. For example, one embodiment of the present invention includes a fixed basket, wherein the ball collecting apparatus must be moved to the location in which the individual is practicing. -
FIGS. 9-11 show theball transport system 38 of one embodiment of the present invention. The ball transport system comprises anupper pulley 200 and alower pulley 204. As described in further detail below, each pulley may comprise left and right pulley members that selectively engage abelt 208. This pulley configuration comprising separate elements that engage lateral edges of the belt is lighter than a pulley in the form of a drum that engages the entire width of the belt. Theupper pulley 200 may be selectively adjustable such that the tension of thebelt 208 can be selectively maintained. More specifically, over time, thebelt 208 may become slacker, which can reduce its effectiveness when the pulleys are rotated. Temperature variations can also cause the belt to slacken. Thus, some embodiments of the present invention employ aplate 212 operatively interconnected to anaxle 216 associated with theupper pulley 200. Movement of theplate 212 will selectively move theaxle 216 upward or downward to alter belt tension. Thelower pulley 204 includes anaxle 220 selectively interconnected to the left or right wheel via a geared interface such that when the left or right wheel rotates, thelower pulley 204 will rotate and move thebelt 208. Theupper pulley 200 can “freewheel” and is not driven by an external force, other than interaction with the belt. Regarding freewheeling, embodiments of present invention employ a gearing system associated with thelower pulley 204 such that it can only rotate in one direction, the direction that facilitates moving balls from the lower opening of the front panel to the upper opening. More specifically, the wheel that rotates the lower pulley is interconnected to the lower pulley by way of a freewheel needle bearing, wherein rotation of the wheels in the opposite direction, i.e., to reverse the ball collecting apparatus, will not rotate thelower pulley 204. -
FIGS. 9-11 also show a plurality of ball guides 250 interconnect to abar 254 that is interconnected to the lower edge of thefront panel 14. The ball guides 250 help direct balls from the lower opening to the ball transport system. The ball guides 250 also help prevent clogging. Although three ball guides are shown, one of ordinary skill in the art will appreciate that any number of ball guides can be employed without departing from the scope of the invention. - Referring additionally to
FIGS. 12 and 13 , the belt transport system selectively engages balls that enter through an opening in the front panel. The balls are urged along the ball collecting surface and engage aball scoop 300 which transitions the balls from a horizontal plane to a vertical plane. After the balls are transitioned in into the vertical plane, they are held byball transport members 400 spaced along the outer edge of thebelt 208. Thebelt 208 includes an inner surface with a plurality ofridges 228 that engage a plurality ofteeth 232 on the pulleys 236 which transmit rotational motion of the pulleys to lateral motion of the of the belt. As thelower pulley 204 is rotated, thebelt 208 is moved which moves the balls upwardly towards theupper pulley 200. After the balls reach the apex of theupper pulley 200, gravity will cause them to disassociate with theball transport member 400 and fall into the basket. -
FIG. 11 is a detailed view showing how one or more balls 500 are initially engaged by thebelt 208. Anupper surface 404 of the ball transport members engages an outer surface of theball 50. Further movement of the ball collecting apparatus rotates thelower pulley 204, which will incrementally move thebelt 208 by way of interaction ofteeth 232 on the pulley andridges 228 on the belt. The balls 500 will eventually come in contact with a ball scoop (not shown) which helps transition the balls 500 from the horizontal plane to the vertical plane. Theball transport members 400 can be spaced such that they closely match the diameter of the ball 500 being collected, which further helps keep the balls 500 onto theupper surface 404 of the ball transport members. -
FIGS. 12 and 13 show ball transport members of one embodiment of the present invention. Theupper surface 404 of the ball left segment employs a curve upper profile which terminates at a curledend 408. The curved profile helps scoop the balls from the ball collecting surface and to maintain them on theupper surface 404 as they are transitioned from horizontal plane to the vertical plane. The ball transport members may include a plurality of stiffeningribs 408 to provide additional rigidity while reducing weight. The ball transport members also include alongitudinal channel 412 or pocket, or series of pockets that extend at least partially the width thereof. Thechannel 412 is adapted to selectively receive a portion of a belt segment as described below. The ball transport members may also include upper andlower feet 416 that engage the outer surface of the belt, which helps increase stability of the ball transport members relative to the belt segment. Stated differently, thefeet 416 help prevent relative motion of the ball transport members relative to the belt transport members and provides a rigid, generally 90° interconnection between the ball transport members and the belt. -
FIG. 14 shows abelt segment 240 of one embodiment of the present invention. As described above, the ball transport members are selectively interconnected to thebelt 208 that generally spans the entire height of the ball collecting apparatus. Thebelt 208 of one embodiment of the present invention is made from a plurality ofsegments 240 interconnected to each other by the ball transport members. Thebelt segments 240 include a generally smooth outer surface and an inner surface withridges 228 that selectively engage corresponding teeth on the lower and upper pulleys. Thebelt segment 240 may also include an upper andlower tab 244 that extend from the outer surface of thebelt segment 240. The tabs ofbelt segments 240 are selectively engaged and held together when placed within the channel (412, SeeFIGS. 12 and 13 ) provided by the ball transport members. Fasteners can interconnect the ball transport members to thebelt segments 240 wherein the fasteners are placed through the upper or lower surfaces of the transport members and maintained by a nut or other fastening device associated with the opposite side of the ball transport members. In this way, the upper and lower edges of thebelt segments 240 are sandwiched together and maintain within the channel of the ball transport members. Those of ordinary skill in the art will appreciate thetab 244 associated with thebelt segments 244 need not extend the entire width thereof and smaller tabs may be employed. Ifbelt segments 240 become worn or damaged, they can be easily replaced by removing the fasteners associated with the ball transport members. -
FIG. 15 shows the pulley of one embodiment of the present invention. As discussed above, the pulleys may comprise two pulley wheels (SeeFIG. 11 ) as shown inFIG. 15 . The pulley includes an outer surface withteeth 232 that selectively engage ridges on the inner surface of the belt segments to help propel the same. -
FIG. 16 shows a belt comprising a plurality of belt segments maintained by the ball transport members. Again, thetabs 244 associated withadjacent belt segments 240 are placed within the cavity provided by the ball transport members. Thetabs 244 may be maintained within thechannels 412 by any common method, such as gluing, welding, ultrasonic welding, fasteners, etc. However, fastening allows for a selective interconnection scheme wherein ball transport members can be selectively removed and replaced if needed.FIG. 16 also shows the interplay between theteeth 232 provided by thelower pulley 204 and theridges 228 provided by the inner surface of eachbelt segment 240. -
FIG. 16 also shows theball scoop 300 associated with one embodiment of the present invention, which is also shown in detail inFIG. 17 . Theball scoop 300 helps transition collected balls being urged rearwardly by ball transport systems from the horizontal plane to the vertical plane. The balls contact aleading edge 304 of theball scoop 300 and ride on theball scoop 300 and are eventually positioned on the upper surface of the ball transport systems. The ball transport systems will then raise the balls upwardly as described above. Because it is often important to maintain a close tolerance between theleading edge 304 and the collecting surface so balls do not jam between theball scoop 300 and the collection surface, one embodiment of the present invention employs a leading-edge roller 308 that facilitates interaction between the balls so they easily move along the ball scoop. The leading-edge roller 308 also may contact the collecting surface to eliminate any gap between the leading-edge 304 and the ball collecting surface. - While various embodiments of the present invention have been described in detail, it is apparent that modifications and alterations of those embodiments will occur to those skilled in the art. It is to be expressly understood that such modifications and alterations are within the scope and spirit of the present invention, as set forth in the following claims.
