Abstract

An apparatus is described having a wide piece of stretchy fabric or other material worn around a person's waist, hips, arm, or thigh, that is adapted to hold balls snuggly against the person while performing an activity, such as playing tennis. Balls may be placed in the front, side or back of the person. Tension from the belt's elasticity, and friction from the fabric contacting the surface of the ball, for example the nap of the tennis ball, prevents the ball from slipping or rolling down the body. Balls may be accessed easily by reaching under the band of fabric from either the top or bottom of the band and pulling the ball out, or applying pressure to the top of the ball through the band and pushing the ball out. The device may be worn independently or may be integrated as an outer layer to a garment.

Description

TENNIS BALL BELT TECHNICAL FIELD

[0001] The present invention generally relates to a device and method for assisting players of ball games, and more particularly to a device and method for holding one or more balls.

BACKGROUND ART

[0002] Holding an adequate supply of tennis balls during play or practice is an unaddressed problem in tennis. In match play, a player requires two balls, holding another ball in reserve during service, in case of a service fault. In practice, drills or casual play, a player, especially a new player, benefits from holding up to six or ten balls on their person, rather than picking balls out of a basket, or retrieving them from the tennis court.

[0003] Several types of tennis ball holders are known in the art. A first type is the cage-type ball holder. These provide a cage, or pocket, that usually attaches to, or is incorporated into, a belt, and which holds each tennis ball individually. A second type of ball holders is pouch-type. These ball holders are worn around the waist or over the shoulder and provide a pouch that holds a number of balls. A third type, underwear for women's tennis skirts, allows one to put the ball in the lower edge of the panty. Each of these devices is cumbersome to use, is limited in the number of balls that can be held, or fails to hold balls during play.

[0004] Thus there is a need in the art for an apparatus that permits a player to have easy access to one or more tennis balls. Such an apparatus should be easy to use and be robust enough to restrain the tennis balls as the player moves about the court.

DISCLOSURE OF INVENTION

[0005] Certain embodiments include an apparatus for holding tennis balls that overcomes the disadvantages of the prior art by providing a belt that can be worn, for example, and without limitation, about the torso, arm, or leg, and which restrains one or more balls between the belt and the wearer's body. The term "ball holder" is used herein, and without limitation, to describe an apparatus that permits a user to store balls, including but not limited to tennis balls. The ball holder is a belt that may be a continuous band or which may be a material with ends that can be secured to from a belt. In one embodiment, a ball holder includes a belt that includes a flexible, expandable fabric. In another embodiment, the belt is a continuous band. In yet another embodiment, the belt includes a fastener and a band to permit the attachment and removal of the ball holder. In yet another embodiment, the belt is a material having two ends that can be tied about the wearer. [0006] Other certain embodiments provide a ball holder that is easy to wear, can accept several tennis balls at a time that are easily reached and removable by the wearer, and restrain the tennis balls within the apparatus while the wearer moves about the court. In one embodiment, the ball holder is primarily a ball storage device, allowing one-handed access to the ball. In another embodiment, the ball holder is worn as an article of clothing, and includes a dri-fit fabric with moisture wicking capabilities.

[0007] Yet other certain embodiments restrain balls using tension and friction from a belt to hold the balls between the wearer's body and a flexible, expandable band made of fabric.

[0008] Certain embodiments provide a belt for holding tennis balls formed from a 140 mm (5.5 inch) wide circular band. In one embodiment the band is a stretch fabric that may include one or more of a nylon, a LYCRA®, a spandex, or a polyester material. The fabric is ergonomically designed to fit snuggly about the player, without binding or twisting, and offering easy access to and retrieval of tennis balls. When the ball holder is worn around the lower waist or hips, it provides a flat profile when empty, until balls are inserted, after which the band bulges about the inserted tennis balls. Balls so held not slip down or pop out of the top or bottom of the band due to the weave of the of the fabric, the fabric content, and snugness of the fit. The width of the band holds the balls firmly against the body without flopping or producing distracting momentum.

[0009] Certain embodiments of inventive ball holders have one or more of the following advantages over the prior art, including:

[0010] Comfort: Cage-type holders are usually made from stiff, hard materials and the balls pop in and out of the cages. The cages poke and scratch during activity. In addition, because the balls are held out from the body they bounce, and may pull on the garment if clipped to a waistband. Pouch-type holders also have bouncing issues, and when not full, the balls may move around during activity. This causes the belt to slide to one side, requiring adjustment. Some also require zippers to open and close the pouch. These can scratch during frequent ball access as well as be stiff and uncomfortable. Certain embodiments described herein reduce or eliminate bouncing, and have primarily fabric contacting the wearer to reduce or eliminate scratching or poking the wearer.

[0011] Modularity: All of the belt-type designs, cage, pouch, or the one proposed herein, offer a modular solution that affords the wearer freedom of choice in their tennis attire without regard for tennis ball storage. For women it eliminates the need to purchase tennis panties and skirts, which many women do not like to wear.

[0012] Access: Accessing the balls quickly with one hand is critical during play. While the cage-type holders offer this, putting the balls in the cage is not always as easy. Accessing the balls in a pouch type holder may require unzipping or unsnapping a closure (two hands), or fishing around for the ball. Certain embodiments described herein offer quick, one-handed access to any of the balls being held, as well as quick storage.

[0013] Storage: The most successful cage-type design stores only one or two balls. The panty type also store at most two balls per leg. Certain embodiments described herein can hold up to 6 balls, and is particularly useful when practicing drills, serves, and rallying in non-match situations.

[0014] Durability: The plastic cages are rigid, and frequently break. Certain embodiments described herein include a high performance textile that will last several years, and has no breakable parts.

[0015] Attractiveness: Certain embodiments described herein can become part of a tennis, or other sporting, outfit when balls are not being stored. Other certain embodiments described herein would, when not holding balls, appear as a wide waistband that lays flat about the wearer. Yet other certain embodiments include a variety of colors and designs to compliment the wearer's outfits.

[0016] These features together with the various ancillary provisions and features which will become apparent to those skilled in the art from the following detailed description, are attained by certain embodiments of a ball holder, preferred embodiments thereof being shown with reference to the accompanying drawings, by way of example only, wherein:

BEST MODE(S) FOR CARRYING OUT THE INVENTION

[0027] The inventive ball holder is described herein with reference to the following embodiments. Those skilled in the art will recognize that other and further modifications may be made thereto without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as fall within the scope of the invention. For example, different materials or dimensions, types of items held, uses of the apparatus, and appendages against to which the apparatus may hold a ball are merely representative and are not meant to limit the scope of the present invention.

[0028] Figure 1 is a perspective view of one embodiment of a ball holder worn around the upper hips, as a belt 2 on a wearer 1. It is preferred that belt 2 is sized to be worn about the wearer, and that it can expand to accommodate one or more items. Belt 2 is illustratively shown in Fig. 1 as restraining a plurality of tennis balls 3. In one embodiment, belt 2 can stretch to accommodate more than one ball, such as up to six tennis balls. The balls may have, for example and without limiation, a diameter of from approximately 64 mm (2.5 inches) to approximately 75 mm (3.0 inches).

[0029] Belt 2 includes at least some expandable material. In one embodiment, belt 2 is formed from materials commonly found in active-wear garments. In another embodiment, the material includes an "expandable" knit, which includes but is not limited to, a ribbed knit, a mesh knit, or a waffle knit, hi one embodiment, the expandable knit is formed of yarns which include, but are not limited to, one or more of a LYCRA®, nylon, spandex, and/or a polyester material.

[0030] Figure Ia is a cross section of the ball holder of Fig. 1, showing one tennis ball 3 between the body of the wearer 1 and belt 2. Belt 2 has an interior surface 2a, an exterior surface 2b, a top edge 2c, and a bottom edge 2d. Tennis ball 3 is held between interior surface 2a and the wearer. The surfaces 2a and 2b may be part of material of belt 2, or alternatively be a surface finish, coating, laminate or some other material or treatment of the belt. In one embodiment, interior surface 2a is woven in a diamond, mesh or basket-type design. When a tennis ball, for example, is accepted within belt 2, interior surface 2a presents a surface that increases the friction on the nap of the tennis ball. Thus, for example, belt 2 expands and forces the nap of an accepted tennis ball into the small pockets created in the weave of interior surface 2a, making it difficult for the accepted ball to roll or slide.

[0031] In one embodiment, belt 2 is worn around the upper hips of a person, which may be a man, woman, or child. In one embodiment, top edge 2c and bottom edge 2d contact the wearer, as shown in Fig. Ia. In one embodiment, exterior surface 2b has a weave that will lay flat, discourage pulls in the yarn, and provides additional tension to keep the balls snug to the body. In one embodiment, exterior surface 2b is ribbed or is flat knit.

[0032] Belt 2 may be constructed on a circular knitting machine, creating a band with no vertical seams. Seams or other bonding may be used at one or both of top edge 2c or bottom edge 2d, resulting in a two layered band (belt).

[0033] Figure 2 is a perspective view with a cut-out, and Figure 3 is a cross sectional view, respectively, of one embodiment of a belt 20, which may be generally similar to belt 2, except as further detailed below. Where possible, similar elements are identified with identical reference numerals in the depiction of the embodiments of Figs. 1, Ia, 2 and 3.

[0034] Belt 20 has a first material 9, forming interior surface 2a, and a second material 10, forming an exterior surface 2b, that are joined at a seam 9a along top edge 2c and at a seam 9b along bottom edge 2d. The seams 9a and 9b may be a sewn, bonded or other type of connection of materials 9 and 10. The materials of interior surface 2a and exterior surface 2b, and thus first material 9 and second material 10, respectively, are described above. Thus, for example, in one embodiment, material 9 is woven in a diamond, mesh or basket-type design. In another embodiment, material 10 is ribbed or is flat knit.

[0035] Fig. 2 shows dimensions of belt 2O₃ which may also apply to various other embodiments of belt 2. The circumference C of belt 20, has a length of top edge 2c or bottom edge 2d that ranges from approximately 0.66 m (26 inches) to approximately 1.17 m (46 inches). The width W of belt 2 (that is, the distance between top edge 2c and bottom edge 2d) is no less than about 75 mm (3 inches), and is, for example, between approximately 100 mm (4 inches) and approximately 150 mm (6 inches). In one embodiment, W is approximately 140 mm (5.5 inches). In another embodiment, the width W is in proportion to the circumference C to create a more flattering visual design.

[0036] Figure 4 is a cross section view of an embodiment of belt 40, may be generally similar to belt 2 or 20, except as further detailed below. Where possible, similar elements are identified with identical reference numerals in the depiction of the embodiments of Figs. 1, Ia, 2, 3, and 4.

[0037] In one embodiment, belt 40 is a one layer construction, where the material is as described with reference to belt 2. In another embodiment, an inside layer 11 and/or an outside layer 12 of belt 40 has the same or different materials applied thereto to change the properties or appearance of the belt. Thus, for example, in one embodiment the material of belt 40 is woven in a diamond, mesh or basket-type design and layer 11 includes a flocking or gummy strips, or dots, to increase the friction of a ball placed between belt 40 and wearer 1.

[0038] Figure 7 is a cross-sectional view and Figures 5 and 6 are perspective views showing the construction of an alternative embodiment of a two layer belt 70. Belt 70 may be generally similar to belt 2, 20, or 40, except as further detailed below. Where possible, similar elements are identified with identical reference numerals in the depiction of the embodiments of Figs. 1,

Ia, 2, 3, 4, 5, 6, and 7.

[0039] Fig. 5 illustrates a first step in forming a belt 70 using two different weaves without a seam. This can be accomplished, for example, using a circular knitting machine to knit a band 50. Band 50 has having an upper section 15 with an upper edge 13, and a lower section 16 having a lower edge 14. Upper section 15 is generally similar to material 10, and lower section 16 is generally similar to material 9. [0040] Fig. 6 shows the band 50 of Fig. 5 being folded over, with upper edge 13 folded to meet lower edge 14. As shown in Fig. 7, edges 13 and 14 are joined at seam 19, which can be a sewn, bonded or knit seam, to create two layers, using only one horizontal seam.

[0041] In an alternative embodiment, belt 2 includes a closure mechanism or can be tied. Thus, for example, belt 2 is not a loop, but has two ends that can be knotted together. As another example, which is not meant to limit the scope of the present invention, Figures 8 and 9 are perspective views of an embodiment of a belt 80 having two ends, each with matching parts of a hook and loop type fastener, such as a VELCRO® fastener, which may be used to secure the belt. Belt 80 may be generally similar to belts 2, 20, 40, or 70, except as further detailed below. Where possible, similar elements are identified with identical reference numerals in the depiction of the embodiments of Figs. 1, Ia, 2, 3, 4, 5, 6, 7, 8 and 9.

[0042] Belt 80 includes has an end 84, matching VELCRO® parts, such as hooks 81 and loops 82 near end 84, and a loop 83 to thread and fold VELCRO® loops 82 over loop 83 and onto VELCRO® hooks 81 to fasten the belt for an adjustable fit. While belts 20, 40, and 70 are bands that must be stepped into or slid over the body to be worn, belt 80 is more easily removable and is adjustable.

[0043] Throughout this specification, the term "comprising" shall be synonymous with "including," "containing," or "characterized by," is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. "Comprising" is a term of art which means that the named elements are essential, but other elements may be added and still form a construct within the scope of the statement.
