Description




FIELD OF THE INVENTION




This invention relates to a game apparatus having a mechanism to drop an object one by one. In particular, this invention relates to a game apparatus having a mechanism to store spherical objects such as golf balls and drop them onto the ground one by one by mechanical means.




BACKGROUND OF THE INVENTION




Men and women of all ages are enjoying the game of golf. Golf is a game to hit the ball having a diameter of about 4.3 cm (centimeter) on the ground with a lesser number of strokes to put the ball in a hole or cup on the green.




The game of golf can be roughly classified in its procedure into a process of placing the ball onto a green where a hole exits by using clubs like iron and wood, and a process of putting wherein the ball on a green is hit into the hole by using a putter.




When a player practices putting or plays putting as recreation, the player has to place a ball on the ground (placement). Hence, in order to practice putting ten (10) times, the player has to place the ball ten times. The routine of placing the ball is frustrating. Moreover, bending down to place a ball may pose significant difficulty for an elderly player or a player with a back pain. When a player practices putting with many balls, the player has to carry a container storing many balls such as a bag.




Thus, a means is desired to place a ball automatically without a player's action to bend over the ground to place a ball. A possible apparatus to achieve this objective can be classified into an apparatus mounting a spherical object drop mechanism to a club, and into an apparatus having a spherical object drop mechanism separately provided thereto.




If the apparatus to mount the spherical object drop mechanism independently from a golf club is to be used, the apparatus having the spherical object drop mechanism needs to be brought over with a player in addition to golf clubs. Moreover, when the spherical object drop mechanism is large, it must be fixed to a specific location on the ground and thus, the ball must be placed only on the same position.




For the apparatus to mount spherical object drop mechanism to a golf club is to be used, it is conceivable to place a ball on the ground with an electric powered mechanism. However, such a structure becomes complex, expensive and inconvenient since an electric power supply such as a battery must be used.




Thus, it is desirable to have a mechanism that allows ball placement on the desired position on the ground by mechanical means with simple structure and low cost.




SUMMARY OF THE INVENTION




Therefore, it is an object of the present invention to provide a game apparatus that allows to drop spherical objects one by one to be placed on desired positions on the ground.




It is another object of the present invention to provide a game apparatus having a container to store spherical objects therein and a mechanism that allows one spherical object to be dropped while preventing other spherical objects from being dropped.




It is a further object of the present invention is to provide a golf ball game apparatus which integrally includes a mechanism for dropping a golf ball one by one on the ground and a storage container of golf balls.




The game apparatus of the present invention has a mechanism allowing to drop a spherical object one by one on the desired positions or spots on the ground. The spherical object drop mechanism includes:




a housing for storing a plurality of spherical objects to allow vertical movements of the spherical objects therein by their own weight;




a first stopper provided in the housing for stopping the vertical movement of the spherical objects;




a second stopper provided in the housing located at a lower location of the first stopper by the distance corresponding to the diameter of the spherical object for stopping the vertical movement or releasing the stop operation of the spherical objects;




a stopper drive means to operate the first stopper and the second stopper for stopping and releasing in the opposite way with each other; and




a knob to operate the stopper drive means from outside.




The game apparatus having the spherical object drop mechanism of the present invention enables to drop a ball one by one onto desired positions on the ground. Since the game apparatus of the present invention has a simple mechanical structure, it is strong and reliable requiring less maintenance, and can be produced economically with low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The spherical object drop mechanism of the present invention attached to a golf club is explained with reference to FIG.


1


. The spherical object drop mechanism


50


is fixed to a golf club


160


by, for example, screws (not shown). Namely, the spherical object drop mechanism


50


is connected to the golf club


160


in a manner to surround a club shaft


165


of the golf club at lower housings


52


and


54


and an upper support


114


.




Between the upper support


114


and the housings


52


and


54


, a ball guide


102


is provided to form an inner space. The inner space is to store spherical objects such as golf balls inserted from the insertion opening of the upper support. It is apparent that such an inner space for ball storage can be achieved by many other configurations, and the ball guide


102


in

FIG. 1

is merely an example.




A handling bar


110


is provided in parallel to the guide rail


102


. The upper end of the handling bar


110


has a knob


112


to pull the handling bar


110


upward. When a user (player) pulls the knob


112


, the handling bar


110


also moves upward, and activates the stopper mechanisms in the spherical object drop mechanism


50


. Thus, the structure of the drop mechanism


50


is so configured as to drop a ball one by one onto the ground by pulling the knob


112


.




It is desirable to use lightweight and inexpensive material such as plastic for the spherical object drop mechanism


50


of the present invention so that the game apparatus as a whole may not become very heavy. By the game apparatus of the present invention, a user can grip the grip area


163


of the golf club to hit a ball on the ground by the club head


167


to enjoy the game or practice putting.





FIGS. 2A-2C

are schematic cross sectional views showing the operation of the spherical object drop mechanism


50


of the present invention. In the example of

FIG. 2

, an upper stopper


10


A and a lower stopper


10


B are provided in the spherical object drop mechanism


50


. The relationship between these stoppers and balls


200


is shown in

FIGS. 2A-2C

. The stopper


10


A and stopper


10


B are made, for example, of straight wire. The configuration of the stopper is merely an example, and it is apparent that many other configurations can be utilized for the same purpose.




The distance between the upper stopper


10




a


and the lower stopper


10


B is established as the size corresponding to the spherical object to be used such as a golf ball. Hence, the distance is established so that only one spherical object can exist between the upper stopper


10


A and the lower stopper


10


B. As will be explained later, the upper stopper


10


A and the lower stopper


10


B operate in the opposite ways with each other (stopper active and stopper release).




The

FIG. 2A

shows the operation of the spherical object drop mechanism


50


of the present invention in a default condition. In this condition, the upper stopper


10


A is open (stopper release), and the lower stopper


10


B is closed (stopper active). Thus, the lower stopper


10


B prevents the ball from dropping onto the ground. The user can carry the game apparatus in this default condition to a desired location or wait for his or her turn to play.




The

FIG. 2B

shows the operation in the spherical object drop mechanism


50


wherein the user pulled the knob


112


(refer to

FIG. 1

) upward. By pulling the knob upward, the handling bar


110


moves upward as well, thereby driving a guide plate


32


(FIG.


3


and

FIG. 4

) to be explained later to activate the stoppers in the drop mechanism. Thus, the upper stopper


10


A closes for stopper activation, and the lower stopper


10


B opens for stopper release. Thus, only the lowermost ball


200


drops onto the ground while the other balls


200


that are positioned above the lowermost ball are prevented from moving by the upper stopper


10


A. and are not dropped to the ground. Thus, only the lowermost ball is dropped to the desired spot on the ground (FIG.


2


C).





FIG. 2C

shows the condition of the spherical object drop mechanism


50


wherein the knob


112


is returned to the original position. By using, for example, springs, the inside of the drop mechanism


50


returns to the original position when the user releases the knob


112


. As described in the foregoing, the lowermost ball


200


is already positioned by being dropped onto the ground. As the knob


12


returns to the original position, the stoppers in the drop mechanism also return to the original condition that is identical to the condition shown in

FIG. 2A

(default condition). Thus, in the situation of

FIG. 2A

, the upper stopper


10


A is opened (stopper release), and the lower stopper


10


B is closed (stopper activation). Thus the balls


200


lower their positions within the drop mechanism in the distance corresponding to the diameter of a ball. By repeating the operation described above, spherical objects can be dropped one by one onto the ground.




As shown above, the ball guide


102


forms a space to store balls and guides the ball to the stopper mechanism in the vertical direction. In this example, the ball guide


102


is configured with a plurality of rod shaped members. However, other shapes are also possible for the ball guide such as a cylindrical shape or a conical shape. By storing several balls in the ball guide


102


, the balls can be conveniently carried along with a golf club. Thus, the balls can be positioned on the ground without requiring the user to bend his or her back.




By the stopper mechanism provided in the spherical object drop mechanism


50


of the present invention, the ball can be dropped one by one as shown in

FIGS. 2A-2C

as described above. The structure and operation of the spherical object drop mechanism


50


of the present invention is explained in more detail with reference to

FIGS. 3-7

.




FIG.


3


A and

FIG. 3B

show the structure of the stoppers in situation corresponding to that shown in FIG.


2


A and

FIG. 2C

, i.e., the default condition. In this situation, the upper stopper


10


A is opened (stopper release), and the lower stopper


10


B is closed (stopper activated). As shown in the exploded view of

FIG. 6

, in the spherical object drop mechanism


50


of the present invention, the guide plate


32


is placed in the housing


54


.

FIG. 3A

shows the guide plate


32


for setting the stoppers in the default condition, and

FIG. 3B

shows the housing


54


.




FIG.


4


A and

FIG. 4B

show the condition of the stoppers wherein the knob


112


is pulled upward by the user as shown in FIG.


2


B. In this condition, The upper stopper


10


A is closed (stopper activation), and the lower stopper


10


B is opened (stopper release).

FIG. 4A

shows the guide plate


32


setting the stoppers to drop the lowermost ball, and

FIG. 4B

shows the housing


54


.




As described above,

FIGS. 3A and 3B

show the condition wherein the knob


112


is not pulled upward (thus in the default condition) as shown in

FIGS. 2A and 2C

. The lowermost ball


200


to be dropped is prevented from being dropped by the closed lower stopper


10


B. Since the upper stopper


10


A is released and is open, the balls above the lowermost balls are on the lowermost ball.




In

FIG. 3A

, the guide plate


32


is comprised of a stopper guide gap


33


to control the operation of the upper stopper


10


A, a stopper guide gap


35


to control the operation of the lower stopper


10


B, a spring storage gap


37


to install therein a spring


40


such as a spring coil, and a top portion


36


linking to the handling bar


110


.




In

FIG. 3B

, the housing


54


is box-shaped to receive the guide plate


32


therein, and is provided with the spring


40


and stopper slits


12


. In

FIGS. 3A and 3B

, the ball guide


102


and the knob


112


are omitted. As shown in

FIGS. 3A and 3B

, the ends of the upper stopper


10


A and lower stopper


10


B are inserted in the stopper guide gaps


33


and


35


of the guide plate


32


, respectively. The other ends of the upper stopper


10


A and the lower stopper


10


B are fixed to the housing


52


shown in

FIG. 6

or FIG.


7


A through attachment holes (not shown).




Before proceeding the explanation with regard to

FIGS. 3 and 4

, an overall structure of the spherical object drop mechanism


50


of the present invention is explained with reference to the exploded view of FIG.


6


. As shown in

FIG. 6

, the spherical object drop mechanism


50


of the present invention is comprised of the housing


52


and


54


, an attachment plate


62


, the guide plate


32


, and a cover


42


. The attachment plate


62


covers the shaft


165


of the golf club with the housing


52


for attachment. In this example, the housing


52


and the housing


54


separately provided are attached with each other. However, they can also be integrally constructed as one unit. The cover


42


fixes the guide plate


32


in the housing


54


.




The stopper slits


12


running in horizontal direction described in the foregoing are provided to the housing


54


. As the guide plate


32


moves in the vertical direction, the upper stopper


10


A and the lower stopper


10


B move in horizontal direction through the stopper slits


12


. The other ends of the upper stopper


10


A and the lower stopper


10


B, i.e., the left ends of the stoppers in

FIG. 6

, are fixed to the housing by suitable means. The upper stopper


10


A and the lower stopper


10


B are made of, for example, metal with elastic property. Hence, the inner ends of the upper stopper


10


A and the lower stopper


10


B are stationary due to the fixation to the housing while the other ends inserted in the guide plate


32


and the stopper slits


12


move in the horizontal direction through the stopper slits


12


, thereby achieving the opening and closing movements of the stopper


10


A and the stopper


10


B.




As shown in FIG.


3


and

FIG. 6

, the upper stopper


10


A and lower stopper


10


B can move only in the horizontal direction while being prevented from the vertical direction movement since the stopper slits


12


extend in the horizontal direction. Thus, in the condition shown in

FIGS. 3A and 3B

, the upper stopper


10


A is located at the slanted portion of the stopper guide gap


33


in the guide plate


32


, and is located at the outer side of the stopper slit


12


. As consequence, the upper stopper


10


A is released. On the other hand, the lower stopper


10


B is located at the vertical portion of the stopper guide gap


33


in the guide plate


32


, and is located at the inner side of the stopper slit


12


. Accordingly, the upper stopper


10


A is closed. In other words, the vertical movement of the guide plate


32


is converted to the horizontal movement of the upper stopper


10


A and the lower stopper


10


B.




In

FIGS. 3A and 3B

, the upper stopper


10


A and the lower stopper


10


B fitted in the guide gaps of the guide plate


32


in

FIG. 3A

are in the same vertical positions as that of the upper stopper


10


A and the lower stopper


10


B fitted in the stopper slits


12


in FIG.


3


B. As shown above, the upper stopper


10


A is located at the slanted portion of the guide gap


33


. Due to the horizontal movement through the slit


12


, the upper stopper


10


A opens. Conversely, the lower stopper


10


B located at the vertical portion of the stopper guide gap


35


will close. Since the balls are prevented from free passage, they will not drop from the drop mechanism


53


.





FIG. 5A

shows the stoppers in the condition of

FIGS. 3A and 3B

seen from the top of the housings


52


and


54


. For the ease of explanation and simplicity, the ball


200


are not shown in Figure SA. As shown in

FIG. 5A

, the lower stopper


10


B is closed, and the ball is prevented from being dropped onto the ground. The upper stopper


10


A is opened that allows enough opening for the passage of the balls. Thus, the balls above the lowermost ball can freely go therethrough.




Referring to

FIG. 4

, the operation of the spherical object drop mechanism


53


when dropping the ball is described in more detail.

FIGS. 4A and 4B

show the condition of the stoppers wherein the upper stopper


10


A is closed and the lower stopper


10


B is opened to drop the lowermost ball when the knob


112


is pulled upward as shown in FIG.


2


B.

FIG. 4A

shows the relationship between the stoppers and the guide plate


32


, and

FIG. 4B

shows the relationship between the stoppers and the stopper slits


12


.




As shown in

FIG. 4A

, the guide plate


32


is pulled upward in the housing


54


. The upper stopper


10


A and the lower stopper


10


B are so positioned as to open the upper stopper


10


A and the lower stopper


10


B. Thus, the upper stopper


10


A is positioned in the inner vertical portion of the stopper guide gap


33


. This movement is converted to the horizontal movement by the stopper slits


12


shown in

FIG. 4B

, thereby closing the upper stopper


10


A. Since the passage of the ball is prohibited, the balls above the lowermost ball will not drop from the drop mechanism.




The lower stopper


10


B is located at the slanted outer portion of the stopper guide gap


35


. When this movement is converted to horizontal movement by the stopper slit


12


shown in

FIG. 4B

, the lower stopper


10


B opens. Thus, the lowermost ball


200


drops to the ground by the gravity. As described above, the upper stopper


10


A is closed to prevent other balls from dropping, and only the lowermost ball is dropped to the ground.





FIG. 5B

is a top view showing the operation of dropping the ball as viewed from the top of the housings


52


and


54


. For the ease of explanation and simplicity, the ball


200


is not shown in FIG.


5


B. As shown in

FIG. 5B

, the upper stopper


10


A is closed, thereby preventing the balls above the lowermost ball from dropping on the ground. The lower stopper


10


B is opened to allow enough space for the passage of the lowermost ball. Thus, only the lowermost ball drops to the ground by the gravity.




After the lowermost ball is dropped, the guide plate


32


moves downward to return to the original position (default position).

FIG. 2C

shows this condition wherein one ball is positioned on the ground and the remaining balls go down one step within the drop mechanism


53


. The upper stopper


10


A is positioned in the slanted outer portion of the stopper


33


. When this movement is converted to the horizontal movement, the upper stopper


10


A opens. Hence the balls above the lowermost ball can freely go through. The lower stopper


10


B is located to the inner vertical portion of the stopper guide gap


35


. When converted to the horizontal movement, the lower stopper


10


B closes. Thus, the balls


200


go one step down within the drop mechanism


50


. This condition is identical to the one shown in FIG.


3


. The top view of the housings


52


and


54


is identical to the one in FIG.


5


A.




By repeating the operation described in the foregoing, the spherical object drop mechanism


50


can drop the balls one by one onto the ground. Since the game apparatus of the present invention has a simple mechanical structure, it is strong and reliable requiring less maintenance, and can be produced economically with low cost.




Although only a preferred embodiment is specifically illustrated and described herein, it will be appreciated that many modifications and variations of the present invention are possible in light of the above teachings and within the purview of the appended claims without departing the spirit and intended scope of the invention.
