Description

  The present invention relates to an upper mounting apparatus for a pachinko machine, and more particularly to an upper mounting apparatus for a pachinko machine that is excellent in operability.

  The present applicant has proposed an upper mounting device that can adjust the inclination angle of the pachinko machine from the gap between the island frame and the frame. The configuration is shown in FIG. The upper mounting device 100 is a device that is fixed to the upper part of the island frame 9 and bites the frame 10. A pachinko machine (not shown) is coupled to the front surface of the frame 10 by a hinge so as to be opened and closed. By inserting the adjusting rod 14 from the gap 15 between the island frame 9 and the base frame 10 and driving the driving means composed of a plurality of gears, the slide bolt of the upper mounting device 100 is rotated, and the grip mechanism is moved back and forth to make a pachinko. Tilt the platform. The pachinko machine can be closed and can be adjusted from the front side, so workability is good. (See Patent Document 1)

  However, further improvement in operability is demanded. The first is the opening / closing operation of the shutter. The upper mounting device is provided with a shutter that can be opened and closed. The shutter is operated to open, then the adjustment rod is engaged with the slide bolt drive means to adjust the tilt angle. When the adjustment is completed, the shutter is closed. Thus, the adjustment rod cannot be engaged with the slide bolt driving means. Here, it is desirable to automatically close the shutter when the adjustment is completed and the adjustment rod is pulled out without performing the operation of closing the shutter again.

  Secondly, the inclination adjustment of the biting portion by rotation of the ratchet bolt can be mentioned. When the thickness of the underframe is thin, the ratchet bolt can be rotated to tilt the biting part upward, but there is the trouble of rotating the ratchet bolt many times. It is desirable to be able to adjust the opening degree.

  Thirdly, there is a lever lowering operation. When the biting portion is bitten into the frame, the lever is pushed up, but the lever is substantially horizontal and is locked close to the lower surface side of the grip base. Therefore, when pulling down the lever and trying to separate the biting portion from the frame, it is difficult for the finger to enter between the lever and the grip base, and it is difficult to pull down the lever. It is desirable to facilitate the operation of pulling down the lever.

  An object of the present invention is to further improve the operability of the upper mounting device of the pachinko machine.

An upper mounting device for a pachinko machine according to the present invention includes a slide base provided with vertical support members on the front and rear sides and fixed to an island frame, a slide bolt rotatably supported on the vertical support member, and rotation of the slide bolt. A slide tap that moves back and forth , a grip base that is moved back and forth by the slide tap and sandwiches the upper side of the frame, and a grip mechanism that is provided at the lower part of the grip base and that bites the lower side of the biting unit a driving means for rotating the first through the sliding bolt comprises a plurality of gears, are inserted into the gap islands frame and underframe and an adjustment rod for rotating said drive means, said drive means by said adjustment rod When the slide bolt is rotated by being rotated, the slide tap moves back and forth and the grip base and the grip machine In the pachinko machine of the upper attachment device sandwiched a base frame can be tilted by moving back and forth, the adjustment rod to said drive means in an open state is engageable, in the closed state to the drive means A shutter that prevents the engagement of the adjusting rod is provided, the shutter is rotatably attached to a pin, and a closing spring biases the shutter in the closing direction, and resists the biasing force of the closing spring. When the shutter is rotated, a hook provided on the shutter engages with the insertion path of the adjustment rod to hold the shutter open, and when the adjustment rod is inserted into the insertion path, the hook When the adjustment rod is removed after the adjustment is completed, the shutter is closed by the urging force of the closing spring.

  The grip mechanism has a ratchet plate and a push spring for urging the ratchet plate in the backward direction, and when the ratchet bolt is pushed forward, the opening degree of the biting portion is held in a narrowed state. When the ratchet plate is tilted forward from the state, the ratchet bolt returns to the initial position by the urging force of the push spring.

  The grip mechanism is composed of a tip side where a lever is pivotally coupled to the base side and the base side by a pin, and a jump spring provided on the pin biases the base side and the tip side in a straight line. When the tip side is pulled down against the urging force of the spring, the tip side is bent.

  The grip mechanism is characterized in that a return spring is provided on a pin that rotatably supports the biting portion so as to urge the pinching portion to open.

  According to the upper mounting device of the pachinko machine of the present invention, when the shutter is rotated against the urging force of the closing spring, the hook provided on the shutter is engaged with the insertion path of the adjusting rod to open the shutter. When the adjustment rod is inserted into the insertion path, the hook is released.When the adjustment rod is removed after the adjustment is completed, the shutter is closed by the biasing force of the closing spring. Even if the shutter is not closed, the shutter can be closed.

  Because the grip mechanism is provided with a ratchet plate and a push spring, when the ratchet bolt is pushed forward, the opening degree of the biting portion can be reduced by one operation (one push), and the ratchet plate can be moved from this state. When tilted forward, the ratchet bolt can be returned to the initial position by the urging force of the push spring. Since it is not necessary to rotate the ratchet bolt little by little to advance or retreat, the operation of adjusting the opening degree of the biting portion becomes easy.

  The lever of the grip mechanism is divided into a base side and a tip side, a jump spring is provided on the pin that connects the base side and the tip side, the base side and the tip side are urged to be in a straight line, and the tip side is bent downward I did it. For this reason, even if the lever is pushed up and there is no gap between the lever and the grip base, the tip end side of the lever can be bent downward and can be pulled down with a finger. That is, the operation of pulling the biting part away from the frame becomes extremely easy.

  Since the return spring is provided on the pin that rotatably supports the biting part, when the ratchet plate is tilted forward and the ratchet bolt is returned to the initial position, the biting part is automatically separated from the frame, It can be returned to the opening position.

The slide bolt 1 is supported by the elongated hole 28 of the first vertical support member 3a constituting the vertical support member 3 so as to be vertically movable and rotatable. The biting portion 6 is supported by a pin 6a, and a return spring 6b is attached to the pin 6a. The lever 7 hangs downward. At the right end, a shutter 20 is provided to close the approach path so that the adjustment rod 14 (see FIG. 12) cannot be inserted in the closed state. Base rails 4 are provided on the left and right. The frame is sandwiched between the grip base 5 and the biting portion 6. The grip mechanism 24 refers to a mechanism including the biting portion 6 and the lever 7.

  FIG. 2 is a plan view of the upper mounting apparatus 100 for a pachinko machine according to the present invention. The slide bolt 1 is supported by a first vertical support member 3 a and a second vertical support member 3 b that constitute the vertical support member 3. The support member 3 is erected at the front and rear ends of a slide base 19 having an opening at the center. The slide bolt 1 is lifted upward by a lifting spring 1a, and a slide tap 2 is screwed together. The bottom of the slide tap 2 is welded to the upper surface of the grip base 5 through the opening of the slide base 19. The slide base 19 is screwed to the base rail 4. Since the slide bolt 1 is supported so that both ends do not move back and forth even if it rotates, the slide tap 2 moves back and forth by the rotation of the slide bolt 1. The ratchet bolt 8 can adjust the opening degree of the biting part 6 by moving the biting part 6 shown in FIG.

  As shown in FIG. 2, a first gear 11, a second gear 12, and a third gear 13 are provided on the rear side of the upper mounting device 100. These gears form drive means 22 for rotating the slide bolt 1. The third gear 13 is connected to the shaft of the slide bolt 1. If the adjusting rod 14 (see FIG. 12) is rotated by engaging the shaft 11 a of the first gear 11, the second gear 12 that meshes with the first gear 11 rotates and further meshes with the second gear 12. The third gear 13 rotates. In this way, the slide bolt 1 can be rotated by the adjusting rod 14, but as a result, the slide tap 2 moves back and forth. When the slide tap 2 moves back and forth, the grip base 5 welded to the lower part of the slide tap 2 moves back and forth. The grip base 5 can be tilted by finally moving the upper portion of the frame 10 back and forth because the biting portion 6 bites the frame. The first gear 11 and the third gear 13 may be engaged with each other, and the second gear 12 may be omitted. Alternatively, the first gear 11 and the second gear 12 may be omitted, and the third gear 13 may be driven by the adjustment rod 14. Furthermore, teeth may be formed on the shaft of the slide bolt 1 and the third gear may be omitted. Although details are not shown, the first gear 11, the second gear 12, and the third gear 13 may be configured to rotate the slide tap 2 instead of the slide bolt 1.

  FIG. 3 is a rear view of the upper mounting apparatus 100 of the pachinko machine according to the present invention. The positions of the first gear 11, the second gear 12, and the third gear 13 are indicated by dotted lines. Below the grip base 5 is a grip mechanism 24 including a ratchet bolt 8. A ratchet plate 21 is provided on the ratchet bolt 8. The lever 7 includes a root portion and a tip portion, and the tip portion is connected to the root portion by a pin 7a, and a jump spring 7b is provided on the pin 7a. The spring 7b is biased so that the base side and the tip side of the lever 7 are in a straight line.

  FIG. 4 is a right side view of the upper mounting device 100 of the pachinko machine according to the present invention. FIG. 4 shows an initial state in which the ratchet bolt 8 is not pushed forward. The push spring 23 pushes the lower side of the ratchet plate 21 so that it always falls backward. An engagement hole 18 is provided in the shaft 11 a of the first gear 11. The engagement hole 18 is on the rear side of the insertion path 27 and engages with the tip of the adjustment rod (see FIG. 12). In the state shown in FIG. 4, the front of the insertion path 27 is blocked by the shutter 20. The shutter 20 is a metal fitting having a hook 20c. The biting portion 6 is in a state where the opening degree is widened toward the front downward direction. This is because the return spring 6b (see FIG. 1) provided on the pin 6a causes the urging force to act on the biting portion 6 counterclockwise. A portion including the ratchet bolt 8 and the biting portion 6 in the lower portion of FIG.

  FIG. 5 is a left side view of the upper mounting apparatus 100 for a pachinko machine according to the present invention. FIG. 5 shows an initial state in which the ratchet bolt 8 is not pushed forward. The biting portion 6 faces the front downward direction. This is because the return spring 6b (see FIG. 4) exerts a biasing force on the biting portion 6 in the clockwise direction in FIG. When the return spring 6b is not provided, the position of the biting portion 6 is determined by friction with the pin, and in order to open the biting portion 6 with a large opening degree, there is a trouble of manually returning the stop position.

  FIG. 6 is a bottom view of the upper mounting apparatus 100 of the pachinko machine according to the present invention. The shutter 20 is rotatably attached to the pin 20a. The pin 20a is provided with a closing spring 20b and urges the shutter 20 to close.

  FIG. 7 is an explanatory diagram of the operation of the shutter 20. FIG. 7A shows the normal state (closed state) of the shutter 20. The shutter 20 is rotatably attached to the pin 20a, and a closing spring 20b urges the shutter 20 in the clockwise direction to close the entrance of the insertion path 27 into which the adjustment rod 14 is inserted. FIG. 7B shows a state where the hook 20c is pushed up by manual operation. FIG. 7C shows that when the hook 20c is pushed up and locked to the bottom hole of the insertion path 27, the inlet of the insertion path 27 is in an open state so that the adjustment rod 14 can be inserted. FIG. 7D shows a state in which insertion of the insertion rod 14 has started. FIG. 7E shows that the hook 20c is released when the insertion rod 14 is inserted deeply. FIG. 7F shows a state in which the adjustment of the inclination angle of the pachinko machine by the insertion rod 14 is completed and the adjustment rod 14 is pulled out from the insertion path 27. In this state, the shutter 20 closes the entrance of the insertion path 27 by the urging force of the closing spring 20b.

  FIG. 8 is a flowchart of the operation related to the shutter 20. (1) First, open the key of the pachinko machine. (2) Next, since the pachinko machine is hinged to the frame 10 (see FIG. 12), the pachinko machine can be opened. (3) Next, the shutter 20 is pushed up by a manual operation to open the shutter 20. (4) Next, close the pachinko machine and then lock the pachinko machine. (5) Next, when the adjusting rod 14 is inserted into the insertion path 27, the hook 20c is released. (6) Turn the adjusting rod 14 to rotate the slide bolt 1 to adjust the inclination angle of the pachinko machine. (7) Finally, when the adjustment rod 14 is pulled out, the shutter 20 closes the entrance of the insertion path 27 by the additional biasing force of the closing spring 20b. Thus, the operation of closing the shutter 20 can be realized by the operation of pulling out the adjusting rod 14. Since the pachinko machine is not opened and closed again, the tilt angle does not shift due to the impact of opening and closing.

  FIG. 9 is an explanatory diagram (Example 1) of the operation of pushing up the lever 7. As shown in FIG. 9A, it is assumed that the ratchet bolt 8 is not pushed. In this state, the biting portion 6 faces downward in the forward direction by the urging force of the return spring 6b. As shown in FIG. 9B, when the lever 7 is pushed up, the lever 7 becomes substantially horizontal and the biting portion 6 bites the frame 10. The upper surface of the frame 10 contacts the grip base 5.

  FIG. 10 is an explanatory diagram (example 2) of the operation of pushing up the lever 7. As shown in FIG. 10A, when the ratchet bolt 8 is pushed in (one operation), the opening degree of the biting portion 6 is narrowed, for example, the biting portion 6 becomes substantially horizontal. When the lever 7 is pushed up in this state, as shown in FIG. 10B, the lever 7 becomes substantially horizontal and the biting portion 6 bites the frame 10. By operating the ratchet bolt 8 in this manner, the thin frame 10 can be bitten. When the ratchet plate 21 is tilted forward in the state of FIG. 10A, the ratchet bolt 8 is pushed back by the push spring 23, and the state shown in FIG. 9A is obtained. Such an operation can also be performed by rotating the ratchet bolt 8 several times.

  FIG. 11 is an explanatory diagram of the operation of pulling down the lever 7. When the lever 7 is pulled down from the state in which the lever 7 is substantially horizontal and the biting portion 6 is biting the frame 10, the tip end portion of the lever 7 is rotated downward and the lever 7 is subsequently pulled down. The tip of the lever 7 is merely urged by a spring 7b and can be pulled down lightly. A finger can be easily placed on the tip of the lever 7 and can be easily operated.

  The upper mounting apparatus for a pachinko machine according to the present invention is excellent in operability, and is suitable as an apparatus for adjusting an inclination angle by inserting an adjusting rod through a gap between the island frame and the frame.
