Tennis ball holder

## Abstract

A tennis ball holder, including a frame having legs joined with at least one upper rail; a carriage having at least one support and a bin, the at least one support joined to the legs and being rotatably joined to the bin, the bin being rotatable within approximately a range of rotation, engaging the at least one upper rail at the extreme points of the range; and tennis balls disposed within the bin.

## Background
FIELD OF THE INVENTION
The present invention relates to devices to hold tennis balls and more particularly devices used to hold large volumes of tennis balls for practice sessions.
BACKGROUND OF THE INVENTION
Tennis is a game enjoyed by millions for exercise, sport and recreation. Many people choose to improve their game and will obtain the services of a tennis professional. Practice sessions with a professional, played on the court, typically involve the professional directing a ball toward the student for the student to hit. Hundreds of balls can be thrown in such a manner during the course of a session. As a result, professionals have found it necessary to have a large bin of tennis balls at their disposal for such session instead of one ball that is chased around after every swing.
Numerous products have been developed to aid the tennis professional in this regard. For instance, devices to pick up and hold tennis balls are described in U.S. Pat. Nos. 6,926,328; 6,494,340; 6,398,040; and 6,354,643 are a few examples. A drawback to all these devices is that they do not allow easy access to balls in the bottom of the bin. As the balls are depleted, the professional must reach deeper and deeper into the bin. A shallower bin is not an option as the bin should hold a sufficient amount of balls for a session.
What is needed is a tennis ball holder that alters its configuration such that the professional does not need to reach deeper and deeper as the balls are depleted. That is the tennis ball holder should be adjustable to lower an upper edge to an elevation commensurate with that of the bottom of the bin when the balls are nearly gone. The ball holder should have a mechanism that retains the balls in the altered configuration such that balls that are in the bin do not inadvertently fall out.
SUMMARY OF THE INVENTION
The present invention is a tennis ball holder that alters its configuration such that the professional does not need to reach deeper and deeper as the balls are depleted. That is the tennis ball holder is adjustable to lower an upper edge to an elevation commensurate with that of the bottom of the bin when the balls are nearly gone. The ball holder also has a mechanism that retains the balls in the altered configuration such that balls that are in the bin do not inadvertently fall out.
The present invention is a tennis ball holder which may include a frame joined to a carriage with tennis balls disposed in the carriage. The carriage may include a bin being rotatable within approximately a ninety-degree range between at least one upper rail of the frame. The bin preferably engaged the at least one upper rail at the extreme points of the rotational range. The bin is desirably fixable intermediate in the range via a selective lock to selectively preclude rotation.
The invention further includes a method of retaining and presenting tennis balls, having the steps of selectively locking a bin in an upright position intermediate a range of rotation; filling a bin with tennis balls; withdrawing tennis balls as desired; and unlocking the bin and rotating the bin to a tilted position as the balls are depleted.
Advantageously, the present tennis ball holder allows easy access to tennis balls within the bin such that the user does not have to reach down to the bottom of a deep bin.
As a further advantage, the bin is tiltable to better reach tennis balls in the bottom of the bin.
As still yet another advantage, the bin may have a stop that prevents balls from rolling out of the bin when in a tilted position.

DETAILED DESCRIPTION
The present invention is a tennis ball holder 10 provided with a frame 20, a carriage 40 and optionally tennis balls 14. The tennis ball holder 10, for use in tennis training on a tennis court 12, is structured to ease the effort required to remove tennis balls 14 positioned deep within the bin 60 as the number of balls 14 in the bin 40 is being depleted. Each of the major components are described below with reference to the best mode of making and using the invention.
The frame 20 has legs 22 joined with at least one upper rail 24 and at least one tray 28. The legs 22 may be joined to castors 26 for ease of transport across a tennis court 12. In the preferred mode, the legs 22 are an inverted U-shaped piece of metal or other solid support material. In such configuration, the upper part of the inverted U forms an upper rail 24. Two such inverted U-shaped parts, provide a total of four legs 22 and two upper rails 24. The upper rails 24 aid in conjunction with other components in preventing the legs 22 from spreading or otherwise dislocating relative to the other legs 22 under the weight of the carriage 40 and the balls 14. Likewise, the tray 28 fixedly joins a lower portion of the legs 22, preventing the legs 22 from spreading or dislocating relative to each other. The tray 28 further provides a convenient area to place other equipment.
The carriage 40 may at least one support, preferably a first support 42 and second support 44, and is joined to the bin 60. The first and second supports 42,44 may join to the legs 22 functionally providing the same resistence to spreading that the upper rail(s) 24 provide. The first and second supports 42,44 rotatably join to the bin 60 with a pivot 46 and may fixedly join to the bin 60 with at least one selective lock 48. The at least one selective lock 48 is positioned to selectively preclude rotation of the bin 60, e.g. holding the bin 60, in an upright orientation, which is normally used when the bin 60 is full of tennis balls 14. The selective lock 48 may be disengaged to rotate the bin 60 to rest on an upper rail 24, preferably either side, lowering an upper edge 74 of the bin 60 such that the balls 14 at the bottom of the bin 60 are more easily accessed. The first and second supports 42,44 may be joined integrally or with attachment mechanism to at least one C-shaped handle 50.
The bin 60 may have first and second sidewalls 62,64 and first and second spill walls 66,68. The first and second spill walls 66,68 preferably are joined to first and second ball stops 70,72 respectively. The ball stops 70,72 are sized and positioned, generally toward the edge 74 of the bin 60 further the bottom 76, to retain tennis balls 14 within the bin 60 when the bin 60 is positioned at an extreme end of the rotational range. The range of rotation is the area between the upper rails 24 in which the bin 60 can turn up to the point where the bin 60 is resting on an upper rail 24, which point is the extreme part of the rotational range. The bin 60, which may be trapezoidal shaped in cross section perpendicular to the axis of rotation may be rotatable within approximately a ninety-degree range engaging the at least one upper rail 24, either side, at the extreme points of the range. The degree of rotation is determinable in conjunction with the outward slant of the spill walls 66,68 of the bin 60 wherein the spill walls 66,68 are oriented horizontal to the ground or with a slight tip toward the bottom 76 of the bin 60 thereby retaining the tennis balls 14 within the bin 60. That is, as the spill walls 66,68 are more vertical when locked in the upright position, the range of rotation can exceed ninety degrees. When the spill walls 66,68 are more horizontal, the range of rotation may be less than ninety degrees. The bin 60 is desirably fixable intermediate in the range of rotation via the selective lock 48 to selectively preclude rotation. Tennis balls 14 may be disposed within the bin 60 for easy access to the tennis instructor.
In operation, the method of retaining and presenting tennis balls 14, may include the steps of selectively locking a bin 60 in an upright position intermediate a range of rotation; filling a bin 60 with tennis balls 14; withdrawing tennis balls 14 as desired; and unlocking the bin 60 and rotating the bin 60 to a tilted position as the balls 60 are depleted. The bin may be rested on an upper rail 24, precluding further rotation in the same direction of the tilt, when in the tilted position and the user may select the direction to rotate the bin 60.
The present invention has been described with reference to the preferred embodiment. This is not limiting as changes may be made in form and substance without departing from the spirit and scope of the legal rights this inventor is entitled to receive under the patent laws of the United States of America.
