GOLF-BALL HEATER BACKGROUND OF THE INVENTION Golf-balls manufactured with gutta-percha cores have a tendency to change their elasticity along with changes in the atmospheric temperature. Especially during cold seasons this elasticity drops down to such an extent as to result in possible errors of various kinds including shorter runs, directional miss-shots, etc. on the golfcourse. Since golf-plays, naturally, require very delicate control of shots, this elasticity factor of the ball plays a vital part in cold climate in particular. This invention, in this connection, provides here a highly handy means of a long-awaited counter-measure against the above.
SUMMARY OF THE INVENTION This invention relates to an entirely new device for heating golf-balls, being designed to provide a golfplayer in cold seasons with properly heated balls with the full elasticity, and is characterized by a handy container of compact size equipped with a heating device and ball-storage and ejection means so as to facilitate easy loading/heating of cold balls and obtaining appropriately heated balls.
BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings, showing by way of an example one form of the embodiment of this invention,
FIG. 1 shows the front view of the invention;
FIG. 2 shows the side view thereof;
FIG. 3 shows the cross-sectional side view along A-A line of FIG. 1;
FIG. 4 shows the cross-sectional view of the invention in the process of heating golf-balls;
FIG. 5 shows a cross-sectional perpendicular view of the invention whereby the ball, ready-heated, is about to be ejected therefrom through addition of a spare ball from the upper opening;
FIG. 6 likewise shows the said cross-section after the heated-ball has been ejected.
DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings, an embodiment of this invention for heating golf-balls, by way of an example, is'illustrated as comprising in combination,
a cylindrical main body 1 which is slightly larger in its inner diameter than golf-balls and equipped with a top-trap 2 and several protruding vertical streaks 10 on the inner wall of the cylinder 1;
a heating device 4 with its heater 3 open upwardly;
an opening 5 with an upper arc-shaped part thereof, cut out in the cylindrical wall 1 above the heater 3, preferably fitted with a hinged door 6 and a pan 7 designed to receive a heated ball when it is to be ejected;
a spring 8, curved upwardly and fitted at one end to the inner wall of the cylinder 1 at a position slightly higher than the pan 7, serving to sustain, several golfballs inserted from above in turn.
In accordance with the present invention, the heater 4, easily dismantled, is ignited with fuel, e.g. benzine, etc.. Of course, the heater can alternatively be operated electrically without any use of inflamable fuel therein. This device of the present invention, contains several balls therein in series, the lowermost ball being sustained by the curved spring 8. The device is easily portable with its book 11, mounted on the outer cylindrical wall 1, and can be hitched to a golf-bag or waist belt of the player either directly or by a strap.
Golf-balls 9contained in the cylinder 1 are heated in turn by the heater 3 from underneath, and as a necessary means of preventing the ball directly above the heater 3 from being heated directly and also excessively beyond a reasonable limit, the receiving pan 7, when preferably provided, serves its protective purpose against scorching of the balls by intercepting the direct heat from the heating source 4.
Now in taking out the heated ball from the device of the present invention, the trap 2 can be opened and a space golf-ball 9 inserted into the cylinder 1, whereby the golf-balls 9 already in the cylinder 1 will bear against the curved spring 8, the lowermost ball 9 pushing down the curved spring 8 (FIG. 5) and at the same time being pushed outwardly toward the direction of the lower opening 5.
With the receiving pan 7, the heated ball 9 is received onto the pan 7, whereby immediately the hooked state of the hinged door 6, so hooked by the upper arc thereof, is disengaged, and the resilient force of the spring 8 automatically opens the door 6, thereby ejecting the heated ball 9 out of the cylinder 1. The heated ball, in the presence of the pan 7, can be securely received by the pan 7, the perimeter of which is bent upwardly for this purpose, more conveniently than in the absence of such pan.
After the ejection, the curved spring 8 springs back to the original state (FIG. 4) and holds the balls in the cylinder 1.
The balls 9, while in the cylinder 1, are constantly pre-heated by the circulation of air inside, heated by the heater 4, and receive more heat as they are pressed down toward the bottom and, in the lowermost position, after long pre-heating, they have received ample heat so as to be maintained approximately about the designated temperature required when in use on the golf-course, thereby obtaining high heat efficiency as well.
In addition, element 12 are ventilation openings formed on the cylinder wall 1 for preventing overheating, and a hole 13 is formed in the hook 11. The cylinder may be covered with insulating materials, e.g. asbestos, etc., and the main body may be made of any materials, e.g. metal, plastics, etc.
From the foregoing, it will be clear that, according to the present invention, golf-balls are ready-heated in the cold seasons in order to maintain the desirable elasticity thereof for play on the golf course, thereby keeping experienced golfers, let alone beginners, from making miss-shots and constitutes a large contribution to golf.
Particularly the special characteristics of superior and novel performancewere not heretofore known, e.g., the device is compact, light-weight and portable; when spare balls are pushed into the cylinder 1, properly heated balls are readily obtainable in turn, and can be securely received by the pan 7 of the door 6; the balls, as they draw near the ejecting position, receive more heat, and consequently the balls, hot enough as well as appropriately hot, are always obtainable.
Furthermore, other advantages include easy removal of heated balls; no untimely dropping of balls nor uneven heat given to respective balls; simple structure and inexpensive cost thereby contributing remarkably to the golf. 7
