Description

TECHNICAL FIELD

This application relates generally to collection systems for tennis balls and, more specifically, to an article for collecting, storing and carrying tennis balls for use in practice sessions, as a replacement for a ball hopper or to complement ball collection devices.

BACKGROUND

During practice or training sessions for sports like tennis a large number of balls may be used to maximize the amount of time spent playing and minimize the time spent tracking down the balls being used in the training session. For example, tennis instructors often use a basket or even a shopping cart full of tennis balls to feed to a student during drills so that a specific technique being taught or practiced can be repeated quickly and for a significant duration to assist in the learning process. Without a large supply of balls, the lesson must be continually interrupted to pick up and collect the balls.

Individuals or small groups who are practicing also use similar devices to facilitate their practice sessions. Tube collectors, as shown in FIG. 1, are often used to speed up the collection of tennis balls during practice sessions or lessons. Tube collectors are long hollow plastic tubes with retention straps at each end that can be used to collect tennis balls on a court by pressing one end of the tube onto a tennis ball on the ground. The tennis ball is pressed through the retention straps into the tube. This device allows a user to avoid having to bend over to pick up a ball and to easily store the balls in the tube. A collection tube can typically hold between 12 and 18 tennis balls.

SUMMARY

The embodiments of the invention relate to an article for collecting sports equipment such as tennis balls and similar items. The embodiments include a bag formed from fabric or mesh that defines at least one opening. This opening may be attached to a collection device to augment the storage capacity and receive collected items from the collection device. The collection device may be a collection tube. The bag may define a funnel shaped region to group the items in one end of the bag. An interior and/or exterior pocket may be coupled to the bag. The bag may be formed from a mesh, a fabric, or a combination of mesh and fabric. The bag may hold over twenty tennis balls.

The bag may have an attachment mechanism to couple the bag to the collection tube. The attachment mechanism may be an interlocking structure, elastic band, drawstring or similar mechanism. The bag may include a strap that enables over the shoulder carriage of the bag or similar hands free carriage of the bag. A first end of the strap may be coupled to a first end of the bag and a second end of the strap may be coupled to a second end of the bag. A shoulder pad may be coupled to the strap. The strap may be adjustable. In another embodiment, the bag may have multiple straps to allow the carriage of the bag as a backpack.

The bag may include a zipper or similar mechanism that opens and closes a second opening of the bag to allow access to the balls stored within the bag. This second opening in combination with the shoulder strap facilitates the use of the bag as a replacement for a ball hopper or similar device. The zipper and second opening may run three fourths of the length of the bag. A third opening in the bag may similarly be controlled by a zipper or similar mechanism. The second opening may be along the top of the bag and the third opening may be along the bottom of the bag. The third opening may be used to easily dump collected balls into a ball hopper or similar device.

DETAILED DESCRIPTION

The invention is described below, with reference to detailed illustrative embodiments. It will be apparent that the invention may be embodied in a wide variety of forms, some of which may be quite different from those of the disclosed embodiments. Consequently, the specific structural and functional details disclosed herein are merely representative and do not limit the scope of the invention.

FIG. 2 is a diagram of a first example embodiment of a bag for collecting balls. In one embodiment, the bag 200 is formed from a mesh material 207. The mesh material 207 may be a nylon, acrylic, natural fiber or similarly constructed mesh. In one embodiment, the mesh material 207 may be a sports mesh capable of withstanding the conditions typical of sports activities including exposure to the elements, relatively high levels of wear and tear and similar conditions. In another embodiment, the material 207 may be a natural or synthetic fabric.

The mesh material 207 may be woven to define a bag with a roughly rectangular shape. The bag may have an opening 203 at one end. The bag 200 may have a range of sizes that expand to enclose from 10 to 45 or more tennis balls 201 or similar objects. The material 207 may be flexible and easily folds and compresses into a small space when empty to allow for convenient storage and transport of the bag 200. In another embodiment, the bag 200 may have any shape or size. In one embodiment, the bag 200 may have a roughly square, oblong, ovoid or similar shape.

In one embodiment, one end of the bag 200 may have a progressively smaller size as it approaches the opening 203, forming a funnel section 211 or similarly shaped section of the bag 200. The funnel 211 section may facilitate the insertion of balls or similar objects into the bag 200 by directing them toward the far end of the bag making space for additional balls to be inserted. The funnel section 211 directs inserted balls toward the far end of the bag 200 with a sloped surface that is slopes downward toward the far end of the bag 200. Gravity naturally pulls balls inserted into the bag 200 through its opening 203 toward the end of the bag 200 opposite the funnel section 211.

In one embodiment, the bag 200 is approximately two and a half feet to three and a half feet in length. The height of the bag may be approximately one to two feet in height. The depth of the bag may be six inches to one and a half feet. FIG. 2B is a diagram showing an end view of the bag 200. The opening 203 is positioned roughly on a centerline of the bag 200 from an end view. The opening 203 is near the upper end of the bag 200. If the bag 200 is held horizontally, the balls inside will not easily fall out because of the positioning of the opening 203 in an upper end of the bag 200.

In one embodiment, the size of the opening may be adjusted using a drawstring 205. The drawstring 205 may loop around the opening 203 to contract the mesh and make the opening 203 smaller. Physical force may be applied to reverse the affects of the drawstring 205 by pulling on the internal edge of the opening 203. Other similar mechanisms may be used in place of a drawstring. For example, a zipper, loop and hook cover and similar mechanisms may be used.

In one embodiment, the opening 203 be specifically adapted to be expanded to fit over the end of a tube collector or similar ball collection device. The maximum size of the opening 203 may be large enough to fit over the end of a tube collector or similar collection device. Once fitted over the end of the tube device or a similar part of a ball collection device the drawstring 205 or similar opening adjustment mechanism may be pulled to tighten the opening 203 around the end of the collection device thereby securing the bag 200 to the collection device. The tightened or secured position of the adjustment mechanism may secure the bag 200 to the collection device by interlocking structures, form fit, friction fit, or similar securing mechanism. In another embodiment, the attachment mechanism may further include a hook and loop mechanism, clasping mechanism or similar securing mechanism. In one example, the mesh 213 may include openings or gaps near the opening 203 that allow protruding sections of the collection device to fit through thereby interlocking the bag 200 with the collection device.

Once secured, the collection device may be tipped or similarly oriented to allow the balls collected to enter the bag 200 through the opening 203. Once the balls have been inserted into the bag, the opening 203 may be widened again and the collection device decoupled. The opening 203 may then be adjusted to a closed position again to secure the balls in the interior of the bag 200. The opening 203 may be enlarged when unattached to a collection device to allow a user access to the balls 201 stored inside or to allow the user to dump the balls 201. For example, the balls may be dumped into a cart, ball machine or similar device.

FIG. 3 is a diagram of a second embodiment of the bag. The bag 300 has a more square shape than the bag 200 of the first embodiment. The bag 300 includes an opening 303 for connecting with a collection device and allowing access to the balls stored in the bag 300. The size of the opening may be controlled by a drawstring 305 or similar mechanism. In addition, other attachment mechanisms or structures may be present to assist the coupling of the bag 300 to a collection device.

In the second embodiment, a strap 317 may be attached to the bag 300. The strap 317 may be used to conveniently carry the bag 300 over the shoulder, across the chest, in hand or in a similar position. In another embodiment, multiple straps may be attached to allow the carriage of the bag 300 as a backpack. For example, the bag may have two lengthwise adjustable straps with padding that a wearer can fit over each shoulder to wear the bag as a backpack.

The strap 317 may be attached through stitching, inter-joined loops, clips or similar mechanisms to the bag 300 at each end of the strap 317. The attachment points of the strap 317 may be at opposite ends of the bag 300 to provide balance in carrying a partial or full bag 300. In one embodiment, the strap 317 may include a shoulder pad 313. The shoulder pad 313 may be an enlarged section of the strap 317 with padding to prevent the strap from focusing the weight of the bag 300 on a narrow strip on the wearer's shoulder causing discomfort to the wearer. The shoulder pad 313 may be repositioned and slide up or down the strap 317 to be best positioned for the comfort of the wearer. Similarly, the length of the strap 317 may be adjusted. The strap 317 may include an adjustment mechanism 315. Any type of adjustment mechanism may be used. In one example, the adjustment mechanism 315 may be plastic or a similar material. The adjustment mechanism 315 may use its shape to create a friction fit with the strap 317 that allows the strap 317 to be looped into the adjustment mechanism 315 and held in place to vary the size of the strap 317 based on the size of the loop in the strap 317.

In one embodiment, the bag 300 may include an outside or exterior pocket 311. The outside pocket 311 may be positioned anywhere on the bag 300. Any number of outside pockets 311 may be placed on the bag 300. The outside pockets may be closeable through a snap flap, zipper, loop and hook mechanism or similar mechanism. The pockets may be used to carry additional items like water bottles, grip tape, sweatbands and similar related paraphernalia. In another embodiment, pockets may be placed in the interior of the bag 300 or may span the interior and exterior of the bag 300.

In one embodiment, the bag 300 may include a second opening 321 controlled by a zipper 319 or similar mechanism. The second opening may be positioned along the bottom of the bag 300. The second opening may be used to dump or remove the contents of the bag 300 easily. In one embodiment, the opening may run for three fourths or more of the length of the bag 300.

FIG. 4 is a third example embodiment of the bag. The bag 400 may be formed from a fabric. The fabric may be tightly or loosely woven. A loosely woven fabric may allow the wearer or others to see the balls 401 inside the bag 400. In one embodiment, a mesh window 423, a clear plastic window or similar structure may be provided to allow a user to see the presence of balls 401 in the bag 400. The fabric bag 400 may have any number of interior or exterior pockets 411, a strap 417, top zipper 421 (or bottom zipper) and similar structures.

In one embodiment, the top opening 425 allows a wearer to easily reach into the bag 400 to retrieve a ball 401. This allows the wearer to use the bag 400 in place of a hopper or cart. Balls 401 may be continuously retrieved for practice sessions or lessons from the bag 400. The bag 400 is carried over the shoulder leaving the arms free to carry a racket and hold a ball 401. Each of the embodiments that include a top opening 425 may be utilized in this fashion to replace the need for a ball hopper.

In one example embodiment, the opening 403 may have an elastic adjustment mechanism 427. The elastic adjustment mechanism 427 may bias the opening 403 to a closed position. The elastic adjustment mechanism 427 may be pulled to an expanded position to allow a collection device to be fit into the opening 403. The elastic adjustment mechanism 427 may be an elastic band that is interwoven into the fabric or mesh to pull the fabric or mesh together.

FIG. 5 is a diagram of one embodiment of a complementary collection device and collection bag. In one embodiment, a bag 500 may include a first opening 503 and a second opening 521, a strap 517, a drawstring 505 and similar structures. A collection tube 535 or similar device may be coupled to the collection bag 500. The collection tube 535 may have a complementary attachment mechanism 537, such as a set of protruding knobs 537 or hooks, clasps or similar structures. For example, a set of knobs 537 may be used to catch the mesh 213 of the bag 500 to hold the bag 500 in place in relation to the tube 535. The bag 500 may be removed from the collection tube 535 by disengaging the mesh 511 or similarly disengaging the complementary attachment mechanisms of the bag 500 and collection device 535.

FIG. 6 is a diagram of a fourth embodiment of the bag. The example bag 600 includes both a top opening 625 and a bottom opening 621. The top opening 625 may be open and closed using a zipper mechanism 633, snap fit mechanism, loop and hook mechanism or similar mechanism. The bottom opening 621 may similarly be opened and closed with a zipper mechanism 619 or similar mechanism. The top opening 625 may be used by a wearer to easily retrieve balls from the bag. For example, the wearer may carry the bag using the strap 617 with the shoulder pad 613 over one shoulder or across the chest while retrieving balls 601 in the bag 600 and holding a racquet. This is convenient for use in practices or teaching sessions and may be used in place of a ball hopper.

The bag 600 may be used in conjunction with a collection device. The bag may be removably connected to the collection device using an end opening 603 and attachment mechanism. For example, the attachment mechanism may include a drawstring 605 to tighten the opening 603 around a portion or port of the collection device.

The bag 600 may include a storage area or multiple storage areas. The bag 600 may include a set of pockets. The bag may include any number of exterior pockets 611 for carrying related paraphernalia, water bottles, personal items and similar article. The bag 600 may include a set of interior pockets 629 for carrying similar articles. For example, the interior pockets may be used to store personal items like keys and wallets in a discrete manner. Pockets or storage compartments may be located on other structures of the bag 600 such as on the strap 617 or shoulder pad 613. For example, the shoulder pad 613 may include a small pocket to store small items for quick and easy access such as sunglasses, sunscreen, wristbands or similar items.

In a further embodiment, the bag may include a belt. The belt may allow a wearer to secure the bag near or around the waist. The belt may allow the wearer to secure the bag to minimize interference with the arms and legs of the wearer for use in practice sessions and lessons. The belt may be a fabric, mesh or similar material. The belt may be attached to one side of the bag and have sufficient length to wrap around the waist of a wearer. In one embodiment, the belt may be detachable from the bag. The belt may be stored in the bag when detached. The belt may be adjustable to fit any waist size of a wearer. The bag may have an external set of loops or similar structure to allow the bag to be removeably attached to the belt.
