Abstract

A ball warming apparatus adapted to completely and effectively heat a cold ball, particularly a bowling ball, to a desirable room temperature. The apparatus may be adapted for selective stationary positioning within a bowling alley for coin-operation, or for selective portable use as a bowling ball bag. The inner wall of the appratus is adapted to closely encompass a bowling ball and to substantially heat the entire peripheral surface of the ball.

Claims

1. A bowling ball warming apparatus comprising:

a first ball receiving member provided with an opening for receiving a conventional bowling ball to be warmed;

said first ball receiving member being spherical and having an inner spherical surface which is dimensioned so as to closely receive and entirely closely cover the spherical peripheral surface of said conventional bowling ball to be warmed;

closure means cooperating with said opening to substantially seal said first member from the ambient;

said first member being provided with inner heating means substantially co-extensive with the entire inner spherical surface of said first member for uniformly heating the entire spherical perhipheral surface of said conventional bowling ball to be warmed;

an electrical power source connected to said inner heating means;

said first member including a base portion pivotably connected to a lid portion, said base portion and said lid portion being each hemispherically shaped;

said closure means comprising mating peripheral edge portions of said base portion and said lid portion;

said base portion being secured to platform means for permitting said first member to be selectively stationarily positioned at a predetermined distance above a suitable horizontal surface;

said base portion and said lid portion being each defined by a substantially continuous outer wall and a spaced apart substantially perforated hemispherical inner wall, said inner perforated wall of each said base portion and said lid portion being provided with a continuous series of spaced apart apertures disposed substantially throughout the entire hemispherical surface of each of said inner walls; and

said inner heating means comprising a blower fan adapted to cooperate with heating coils so as to direct heated air into the space between said outer wall and said inner wall of both said base portion and said lid portion and through said apertures of said perforated inner walls so as to heat the entire peripheral surface of said conventional bowling ball to be warmed.

2. A ball warming apparatus in accordance with claim 1, wherein:

said apparatus is further provided with means for actuating said apparatus by coin operation.

3. A ball warming apparatus in accordance with claim 1, wherein:

said lid portion is provided with a handle disposed on the continuous outer wall thereof;

said blower fan and heating coils are disposed adjacent an opening provided in said continuous outer wall of said base portion so as to direct heated air therethrough;

said mating peripheral edge portions of said base portion and said lid portion include mating air passage means for permitting said heated air to pass from the space between said outer and inner wall of said base portion to the space between said outer and inner wall of said lid portion; and

said mating peripheral edge portions being further provided with at least one air vent.

4. A ball warming apparatus in accordance with claim 3, wherein:

said apparatus is further provided with means for actuating said apparatus by coin operation.
