Tennis ball conditioner

Abstract

An apparatus for the conditioning, storage and transportation of tennis balls. The tennis ball conditioning, storage, and transportation apparatus is used to condition tennis balls, primarily by heating to a desired operating temperature. Conditioning modifies the internal pressure of the balls and warms the composition of the balls to the desired playing temperature. The tennis ball conditioning, storage, and transportation apparatus includes a housing which may have handles and which has an interior which contains heating and/or cooling elements and which functions as a conditioning and storage chamber. The chamber is divided by a screen upon which the balls rest. A thermostatically controlled heater, cooler and fan achieve the desired temperature then stabilizes the balls at the desired temperature.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to of sporting goods.

More particularly, the present invention relates to of tennis. In particular the present invention relates to an apparatus to improve the bounce performance of cold tennis balls.

It is known that the bounce performance of a tennis ball varies approximately forty percent as the temperature of the ball drops from a temperature of seventy degrees Fahrenheit to a temperature of thirty degrees Fahrenheit. Therefore when a ball is cold, the bounce performance of the ball is significantly diminished making it difficult to play tennis. This is a universal problem experienced by all players of the sport.

2. Background Art

U.S. Pat. No. 4,372,095 (issued to De Satnick on Feb. 8, 1983) discloses a device using a needle to pierce a tennis ball and inject a gas into the ball to adjust the pressure within the ball.

In contrast, the tennis ball conditioner of the instant application utilizes heat to increase the internal pressure of the ball and to heat the entire composition of the ball to improve the bounce performance of the ball.

There is no invasive puncturing of the ball and no possibility of subsequent leaking due to the piercing of the ball membrane.

Thus, the inventive tennis ball conditioner of the instant application solves the cold tennis ball bounce performance problem by rapidly heating tennis balls to the desired operating temperature.

BRIEF SUMMARY OF THE INVENTION

The tennis ball conditioner apparatus comprises an insulated housing with internal thermostatically controlled heating, cooling and variable speed fan to quickly warm tennis balls to the operating temperature. The balls are then stabilized or maintained at the desired operating temperature. The apparatus conditions the balls for use primarily by heating and also stores a varying number of balls ready for transportation.

Playing tennis with cold tennis balls that will not bounce properly is a universal problem experienced by all players of the sport when the ambient temperature is too cold.

The bounce performance of a tennis ball decreases by approximately 40% as temperature decreases from 70 degrees F. to 30 degrees F.

The tennis ball conditioner solves this problem by rapidly heating tennis balls to the desired operating temperature then stabilizing said balls at the desired temperature.

DETAILED DESCRIPTION OF THE INVENTION

The preferred embodiment of the tennis ball conditioner of the present invention is disclosed hereby and in FIGS. 1 through 4 of the instant application. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

FIG. 1 is a functional block diagram depicting one embodiment of the tennis ball conditioner. The tennis ball conditioner, according to the invention includes an Off/Hi/Lo switch 102 to energize the temperature control 112. Power source 114 may have a plurality of voltages. Off/Hi/Lo switch 102 selects the heat range and the blower speed. Off/Hi/Lo switch in either the Hi or Lo positions energizes the fan 106, the heater 108 and the cooler 110. Temperature sensor 118 senses the ball temperature. Thermostat 104 sets the desired ball temperature. The actual ball temperature is depicted on temperature display 116.

FIG. 2 depicts a side view of the tennis ball conditioner in on embodiment of the tennis ball conditioner. The tennis ball conditioner according to the invention includes a housing 100 to contain the balls and all of the components of the tennis ball conditioner. Temperature sensor 116 detects the temperature of the balls. Screen 122 divides the upper and lower chambers of the housing. Screen 122 provides a surface for the balls 120 to rest upon. Air flow freely passes through the screen 122, permeating all area inside the housing. Inlet vent 124 provides air flow to the fan 106, which then is forced through the heater 108 and the cooler 110. Electrical circuitry is managed by the temperature control 112. Air is exhausted through exhaust vent 126. Handle 140 provides for ease of transportation.

The tennis ball conditioner shown in FIGS. 2, 3, and 4 of the drawings has a housing 100 which includes a cover 128.

FIG. 3 is a front view of the tennis ball conditioner in one embodiment of the tennis ball conditioner. Cover 128 provides interior access to the storage and conditioning chamber within the housing. Off/Hi/Lo switch 102 energizes the circuitry of the tennis ball conditioner. Thermostat 106 provides the control to set the desired temperature within the housing and therefore the temperature of the ball's. Air intake 124 provides air flow into the heater and cooler. Air intake cover 134 provides protection from the fan blades. Insulation 138 lines the interior of the housing. Handle 140 provides for ease of transportation.

FIG. 4 is a rear view of one embodiment of the tennis ball conditioner. Exhaust vent 126 provides for controlled air circulation.

For clarity, within this document all reference to the top and bottom of the tennis ball conditioner will correspond to the tennis ball conditioner of the FIG. 2 when oriented such that the text is upright corresponding to top of the tennis ball conditioner, and the bottom of the figure when oriented such that the text is upright corresponding to the bottom of the tennis ball conditioner. Likewise, all reference to the front of the tennis ball conditioner will correspond to the leftmost part of the tennis ball conditioner as viewed in FIG. 2 when oriented with the text upright, and all reference to the rear of the tennis ball conditioner will correspond to the rightmost part of the tennis ball conditioner as viewed in FIG. 2 when oriented with the text upright.
