Description

[Detailed Description of the Invention] The present invention relates to a tip mechanism for a pachinko machine that can ensure the operation of the blades and increase the fun of the game as a pachinko machine.

Conventionally, pachinko machines have a so-called tulip mechanism, or simply called a tulip, and when the ball hits this mechanism, a pair of blades that are set up facing each other at a certain interval open and collapse in the left and right directions, like the opening of petals of a flower. However, there is a known mechanism in which when the ball then falls onto the blades in the open state, the left and right blades stand up like the petals of a flower closing and return to their original state.

In this way, in the conventional tulip mechanism, each time a ball hits the open blade and falls, the blade stands up and returns to its original state, and it does not matter how many hit balls fall onto the blade. However, there was no known mechanism for keeping the blades open for a certain period of time.

With conventional tulip mechanisms, if a ball bounces off a nail on the board of a pachinko machine and hits the blade in the open state, the blade stands up and cannot be opened again, or if multiple balls hit at once. If it fell onto an open blade, it could become jammed or remain closed, impairing the original function of the chute lip mechanism and causing customer displeasure.

This invention was made with attention to the above points,
By operating a pair of tulip blades by a ball guide lever plate via a pair of L-shaped lever members, the open state of the tulip blades is maintained for a certain period of time regardless of the falling of the hit ball onto the tulip blades. It is an object of the present invention to provide a tulip mechanism which can have a structure that allows the tulip blade to operate reliably, and which does not close due to vibration or the like.

An embodiment of the present invention will be described below based on the accompanying drawings.

In the figure, H is the tube mechanism according to the present invention,
It has a substrate 1 and is attached to a pachinko board surface via this substrate 1. 2 is a front plate provided in front of the substrate 1 at a predetermined interval. The lower end of the front plate 2 is connected to the lower end of the substrate 1 via the bottom plate 2a. Reference numerals 3a and 3b denote tulip blades, which are rotatably provided between the base plate 1 and the front plate 2 via pins _P1 and _P2 .

On the other hand, a hollow part 1a is formed in the center of the substrate 1, and a narrow opening part is formed in the lower part of the substrate 1, which is continuous with the hollow part 1a. This is the exit _O2 . Reference numeral 4 designates a downwardly opened U-shaped frame body spaced apart from the substrate 1 at a predetermined distance and corresponding to the hollow portion 1a. Reference numeral 5 denotes a ball guide lever plate, which is an opening gap 4a between the hollow part 1a of the base plate 1 and the frame body 4.
The front half of the shaft is loosely inserted into the shaft, and slightly rearward from the center thereof, it is supported by a shaft _P3 so as to be able to move up and down. This axis P ₃ is horizontally suspended between the side walls W ₁ and W ₂ . A ball guiding path R is formed by the side walls W ₁ , W ₂ and the base end wall W ₃ . The ball guiding path R surrounds the ball guiding lever plate 5 on its sides, thereby guiding the ball. O ₁ is side wall W ₂
and a bulb outlet formed by cutting out the proximal wall _W3 .

The ball guide lever plate 5 has a tip portion 5a and a tip portion 5.
Tapered portion 5b and base end portion 5 formed adjacent to a
It has c. The base end portion 5c is slightly bent upward and has a slope inclined in the side wall _W2 direction, so that the ball rolling on the ball guide lever plate 5 can be smoothly passed from the ball discharge port _O1 . It is beginning to be excreted. As is clear from the illustration, the ball guide lever plate 5 is heavy at its tip, so unless an external force is applied, the tip will descend to a horizontal state.

_S1 is a stopper portion that limits the movement of the base end 5c of the ball guide lever plate 5, and _S2 is a stopper bar that limits the movement of the center portion of the ball guide lever plate ₅ . The frame body 4 is provided horizontally so as to be located in the opening gap 4a of the frame body 4.

The pins P ₁ and P ₂ extend from the substrate 1 to the front plate 2 and the frame 4 to the rear. L ₁ and L ₂ are L-shaped lever members,
It is rotatably attached to pins P ₁ and P ₂ located between the substrate 1 and the frame 4. 6 is a weight portion provided at the base end of the L-shaped lever members L ₁ and L ₂ ;
When there is no load, the lever members L ₁ and L ₂
It functions so that it is located in a horizontal state as shown in FIG. 7 is the lever member L ₁ ,
This is a stopper member for stopping _L2 in a horizontal position. The lever members L ₁ , L ₂ are configured so that they can come into contact with the inner lower part Y of the tube lip blades 3 a, 3 b, and the ball guiding lever plate 5 can come into contact with the upper surface side of the lever members L ₁ , L ₂ . is attached to. Then, when the ball guide lever plate 5 is raised as shown in FIG. 5, the proximal corner portions l of the lever members L ₁ and L ₂ and the tapered portion 5 b are configured to come into contact with each other in a biting state. As a result, accidents such as the ball guiding lever plate 5 falling due to vibration etc. are eliminated.
In other words, runaway is prevented.

The inner upper part X of the tube lip blades 3a and 3b is tapered toward the substrate 1, so that the hit ball B is
When the ball falls between the tulip blades 3a and 3b in the upright state, the ball is pushed out in the direction of the board 1 by the taper and guided onto the ball guide lever plate 5.
The operation will be explained below based on the above configuration.

Tulip blade 3 illustrated in Figures 1 to 4
When a and 3b are in an upright state, the ball guide lever plate 5 is in a lowered state, that is, in a substantially horizontal state, and presses the L-shaped lever members L ₁ and L ₂ left and right, and this L-shaped lever member L ₁ , L ₂ is tube tip blade 3
The lower inner surfaces Y of a and 3b are further pressed and separated from each other to form a vertical state. In this state, when the hitting ball B falls between the tube blades 3a and 3b, as described above, the upper part of the inner surface
The taper causes the substrate to be pushed out in one direction. As shown in FIGS. 3 and 4, the tip of the ball guiding lever plate 5 extends from the base plate 1 to the tube tip blade 3.
Since the ball B protrudes between the tubes a and 3b, the ball B that falls between the tulip blades 3a and 3b is
As shown in FIGS. 2 to 4, the ball guide lever plate 5 is moved toward the base end, and the base end 5c of the ball guide lever plate 5 is moved downward, that is, as shown in FIG. The lever plate 5 is in a raised state, and the ball is discharged from the ball discharge port _O1 and processed as a hit ball.
When the tip end of the ball guide lever plate 5 rises and the base end descends in this way, at the same time, the L-shaped lever members L ₁ and L ₂ are released from being pressed by the ball guide lever plate 5, and the weight part 6, Due to the load of 6, the tulip blades 3a and 3b become horizontal as shown in Fig. 7, and the pins P ₁ and P ₂
It rotates around , and assumes a laid-down state, that is, an open state, as shown by the imaginary line in FIG. 1 and in FIGS. 5 and 6.

In the state shown in FIGS. 5 and 6, when the ball B falls onto the open tube blades 3a and 3b, the ball B hits the tip of the ball guiding lever plate 5 which is in the raised state, and the ball guiding lever Push down the plate 5 to bring it to a lowered horizontal state, and release the L-shaped lever member.
Push L ₁ and L ₂ to the left and right to make them vertical, and raise the tube blades 3a and 3b as shown in Figure 1.
Return to the state shown in Figure 4. Hit ball B at this time
As shown in FIG. 5, the balls fall without being guided to the upper surface of the ball guide lever plate 5, reach the bottom plate 2a, are ejected from the lower ball outlet _O2 formed at the bottom of the base plate 1, and hit the ball. Treated as a sphere.

In this way, the tulip blade 3a in the open state,
Since 3b is only lying to the left and right due to its own weight, even if it is hit by a bouncing ball from the outside or the pachinko machine vibrates, it will only temporarily rotate and return to its original open position. It returns to Unless the tip of the ball guide lever plate 5 is lowered to a horizontal position and the L-shaped lever members L ₁ and L ₂ are pushed down, the tube lip blades 3a and 3b will not stand up and be closed. Moreover, as described above, the tapered portion 5b of the ball guiding lever plate 5 and the proximal corner portions l of the L-shaped lever members L ₁ and L ₂ are designed to bite into each other, so that the ball guiding lever plate 5 It is reliably prevented from descending and returning to the horizontal position.

Furthermore, in the state shown in FIG. 5, if the base end 5c of the ball guiding lever plate 5 is kept pressed for a certain period of time by a pressing means equipped with a timer (not shown), how many balls will hit the tip blades 3a and 3b? Even if the ball falls, the ball guide lever plate 5 will not descend to a horizontal state, so all the hitting balls will fall as they are to the bottom plate 2a and exit from the lower ball outlet _O2 . Therefore, the rate of winning balls during this period increases, and the content of the pachinko game becomes even more interesting.

Furthermore, as shown in FIG. 8, if hook pieces F, F are provided on the upper surfaces of the L-shaped lever members L ₁ , L ₂ , and the ball guide lever plate 5 can be engaged with the hook pieces F, F, then, Ball guide lever plate 5 and L-shaped lever member L ₁ ,
The engagement operation with _L2 becomes more reliable, and such a configuration can also be adopted when only the same action as the conventional one is performed.

If these hook pieces F, F are constructed so that they can be cut with nippers or the like, there is the freedom to remove them or leave them as they are depending on the purpose of use.

In the embodiment shown in FIGS. 1 to 6, the weight portion 6 and bearing portion of the L-shaped lever members L ₁ and L ₂ are connected to the substrate 1.
An example is shown in which the lever members L 1 and L 2 are positioned between the lever members L 1 and the frame 4, but the lever members L ₁ and L ₂ are located between the tube blades 3 a and
The attachment position is not limited to the illustrated example, as long as it has the effect of pressing the lower portion Y of the inner surface of 3b. For example, the weight portion 6 and bearing portion of the lever members L ₁ , L ₂ may be positioned between the substrate 1 and the tube blades 3 a, 3 b, and the orientation of the lever members L ₁ , L ₂ may be With the front plate 2 and the tulip blades 3a, 3 in the opposite direction,
The weight portions 6 and bearing portions of the lever members L ₁ and L ₂ may be positioned between the lever members L 1 and L 2 . In these examples, the tulip blades 3a,
Cut out the corresponding parts of 3b and attach lever members L ₁ and L ₂
The bearings, etc. will be installed.

As described above, the present invention is a tulip mechanism in which a pair of tulip blades are operated by a ball guide lever plate through a pair of L-shaped lever members, so that the tulip blades can operate reliably and vibrate. The game is designed so that malfunctions do not occur due to causes such as the above, and in addition, the game adopts a configuration that can maintain the open state of the tulip blade for a predetermined period of time regardless of whether a hit ball falls onto the tulip blade. This has the effect of increasing interest in the game.
