(b) Description of the Prior Art
- SUMMARY OF THE INVENTION
Many game machines, such as basketball machine, baseball machine, dartboard game machine, etc., are known for playing a throwing action. When using a throwing game machine, the player must throw the ball or dart by hand. There is also known a throwing game machine in which the player must throw a ball, coin or token to a predetermined location by spring means or the like for a striking action. However, this kind of throwing game machine simply allows throwing of a ball, coin or token in one particular direction or one of a limited number of directions. Because this kind of throwing game machine does not allow adjustment of the throwing angle and direction, it cannot increase the level of difficulty of the game task or enhance the entertainment effect.
The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a thrower for coin-throwing game machine, which allows quick and accurate adjustment of the throwing angle in any direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 10 corresponds to FIG. 9, showing the housing opened from the thrower.
As shown in FIGS. 1-3, a thrower for game machine in accordance with the present invention comprises a joystick 1, a thrower holder 2, a tilting bar 3, a swinging bar 4 and a connection frame 5.
The joystick 1, as shown in FIG. 4, comprises a stick 11 and a base, which is formed of a fixed plate 12, a movable plate 13, a displacement block 14 and an actuating plate 15. The stick 11 is inserted in proper order through the fixed plate 12, the movable plate 13 and the displacement block 14. The joystick 1 further comprises a locating frame 16 affixed to the fixed plate 12, a switch holder 17 affixed to the bottom wall of the locating frame 16 and an induction switch 18 mounted in the switch holder 17. The fixed plate 12, the movable plate 13 and the displacement block 14 each have a through hole 121, 131 and 141, respectively, for the passing of the stick 11. The stick 11 has a neck 111 coupled to the through hole 141 of the displacement block 14, an axially movable tip 112 disposed at the bottom side, and a control button 113 disposed at the top side and operable to move the tip 112. The fixed plate 12 has a pivot hole 122 located on each of the front and rear sides thereof in Y-axis direction. The displacement block 14 has a pivot hole 142 located on each of the left and right sides thereof in X-axis direction. The movable plate 13 has a pivot hole 132 located on each of the front and rear sides thereof in Y-axis direction and pivotally coupled to the pivot hole 122 of the fixed plate 12, a pivot hole 133 located on each of the left and right sides thereof in X-axis direction and respectively pivotally coupled to the pivot holes 142 on the displacement block 14. The actuating plate 15 is mounted in the switch holder 17, having an extension strip 151 disposed at one side for touching the triggering button 181 of the induction switch 18 and a concave bearing portion 152 disposed at the other side and vertically stopped against the tip 112 of the stick 11. The player can operate the control button 113 to control the extension and retraction of the tip 112. When the player presses the control button 113, the tip 112 is forced outwards against the concave bearing portion 152 of the actuating plate 15 to trigger the triggering button 181 of the induction switch 18, thereby turning on an electromagnetic valve 22 (this will be described further).
The thrower holder 2, as shown in FIG. 3, is pivotally coupled to the casing 20, having a through hole 23 cut through the top and bottom sides thereof, a guide block 21 fixedly mounted on the top side and an electromagnetic valve 22 mounted on the bottom side. The guide block 21 defines therein a retaining groove 211 in communication with the through hole 23 for holding an object to be thrown (for example, coin or token 6), having a stop member 212 disposed in the retaining groove 211 (see FIG. 5) and a substrate 213 mounted on the back side. The substrate 213 carries a sensor switch 214 adapted to detect the presence of a token 6 in the stand-by position. The electromagnetic valve 22 has a valve rod 221 insertable through the through hole 23 and the retaining groove 211 (see FIG. 5). Further, a ball socket 24 is provided at the front side of the thrower holder 2 to hold the tilting bar 3.
The tilting bar 3, as shown in FIG. 3, has a ball 31 disposed at its one end and pivotally coupled to the ball socket 24 at the front side of the thrower holder 2 and a ball socket 32 disposed at its other end and pivotally coupled to the displacement block 14 of the joystick 1. According to the present preferred embodiment, the tilting bar 3 is an L-shaped bar. When the stick 11 of the joystick 1 is tilted back and forth (see FIG. 6), the displacement block 14 is driven to tilt the tilting bar 3, thereby lifting or lowering the thrower holder 2 to change the sloping angle of the guide block 21 as desired.
The swinging bar 4 is a long straight bar having its one end pivotally coupled to a lug 134 at the movable plate 13 of the joystick 1 and its other end pivotally coupled to the connection frame 5. When the stick 11 of the joystick 1 is tilted leftwards or rightwards (see FIG. 7), the movable plate 13 is driven to bias the swinging bar 4, causing the connection frame 5 to bias the thrower holder 2 leftwards or rightwards.
The connection frame 5, as shown in FIG. 3, is a U-shaped frame bar pivotally coupled to the thrower holder 2, having a lug 51 disposed at its one side remote from the thrower holder 2 and pivotally coupled to the swinging bar 4. Therefore, when the player swings the swinging bar 4, the thrower holder 2 is synchronously biased.
After the joystick 1, the thrower holder 2, the tilting bar 3, the swinging bar 4 and the connection frame 5 have been assembled to create a thrower, a coin or token 6 can be inserted into the retaining groove 211 of the thrower holder 2. After one coin or token 6 is inserted into the retaining groove 211 of the thrower holder 2, the player can tilt the stick 11 of the joystick 1 back and forth and/or left and right, causing the tilting bar 3 or the swinging bar 4 to tilt the thrower holder 2, thereby changing the sloping angle of the thrower holder 2 in the X-axis or Y-axis direction. After adjustment of the sloping angle of the thrower holder 2, the player can operate the joystick 1 to switch on the induction switch 18, causing the valve rod 221 of the electromagnetic valve 22 to strike the coin or token 6 away from the retaining groove 211 of the guide block 21 toward the desired direction (see FIG. 8). Thus, one throwing task is done.
Further, the thrower is accommodated in a housing 7 that has internal frame boards for the mounting of the component parts of the thrower. After installation, the stick 11 of the joystick 1 extends out of the housing 7. Further, a shading plate 114 is fixedly mounted on the periphery of the stick 11 and kept in proximity to the bottom surface of the top panel of the housing 7 to keep the inside of the housing 7 from sight. Further, the housing 7 has at least one coin slot 71 and a coin-return device 72. Further, the housing 7 has a track 73 located on the inside for guiding an inserted coin or token 6 from the coin slot 71 to the retaining groove 211 of the guide block 21 at the thrower holder 2 for throwing.
The structure of the joystick 1 is substantially similar to similar conventional designs, comprised of the aforesaid stick 11, fixed plate 12, movable plate 13, displacement block 14, actuating plate 15, locating frame 16, switch holder 17 and induction switch 18. Further, the arrangement of the tip 112 and control button 113 of the stick 11 is also of the known design. Therefore, no further detailed description of the joystick 1 is necessary. Further, other modifications and changes may be made to the joystick 1 without departing from the spirit and scope of the invention.
Referring to FIG. 9, the thrower is mounted with the housing 7 and used in a coin-throwing game machine 8, and operable to throw coins or tokens 6 onto carrier plates 81 in the coin-throwing game machine 8. When the weight of coins or tokens 6 accumulated on one carrier plate 81 surpasses a predetermined value, the carrier plate 81 will be turned over, causing the accumulated coins or tokens 6 to fall. Thus, the player can earn all the fallen coins or tokens 6 or an equivalent coupon as a prize. Therefore, the invention increases the level of difficulty of the game task and enhances the entertainment effect.
Referring to FIG. 10, the housing 7 can be turned outwards relative to the thrower to facilitate maintenance. Sound and light generating circuit means may be installed in the coin-throwing game machine 8 to crease sound and light effects.
Further, the thrower of the present invention is not limited to the application for throwing coins or tokens 6. Alternatively, the thrower can be modified to change the design of the track 73 and the thrower holder 2 for throwing balls or any other objects.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
