A second engagement claw 35 used for locking the glass frame 5 is formed on the upper and lower ends of the back claw member 34 so as to protrude in the left direction in the figure. As shown in FIG. 4, the upper and lower second engaging claws 35 are formed so that their tip portions protrude from the upper and lower long holes 3 b of the front frame 3, and the second claw holder 8 of the glass frame 5. It is the structure which can be hung from below. The upper and lower second engaging claws 35 are configured so that the front claw member 32 and the back claw member 34 of the second engaging claw member 30 slide along the guide plate 18 to the upper limit position (locking position). The two-nail support 8 is held in engagement.
That is, the second engaging claw 35 corresponds to the engaging claw for locking the glass frame of the present invention.

  The tip end portion of the second engagement claw 35 is cut out in a substantially trapezoidal shape, and a first inclined surface 35u, a second inclined surface 35e, and a V-shaped groove 35v are formed in order from the top. The first inclined surface 35u is a portion that presses the second claw support 8 of the glass frame 5 in the opening direction of the glass frame 5 when the glass frame 5 is unlocked, and the front end side becomes higher in the downward state. Is provided with an inclination. The V-shaped groove 35v is a portion that is hung on the second claw holder 8 of the glass frame 5, and the depth dimension thereof is set according to the second claw holder 8 of the glass frame 5.

  The second engaging claw 35 is formed with a third inclined surface 35d at a position closer to the tip than the V-shaped groove 35v. The third inclined surface 35d is a portion where the second claw support 8 of the glass frame 5 comes into contact with and slides when the glass frame 5 is locked, and the closing force of the glass frame 5 is applied to the second engaging claw. It functions to convert to a pressing force of the member 30. The third inclined surface 35d is provided with an inclination so that the tip side is lowered in an upward state.

  Inclined elongated holes 34u and 34d are formed in the upper end portion and the lower end portion of the back claw member 34, respectively, and the connecting pin 18x fixed to the guide plate 18 of the fixed base frame 15 in the inclined elongated holes 32u and 32d. , 18y is passed. With this configuration, the back claw member 34 can slide relative to the guide plate 18 by the length of the inclined long holes 32u and 32d. Here, since the inclined long holes 34u and 34d have lower ends located slightly on the left side (outside) from the upper ends, the second engaging claws 35 are in a state where the back side claw member 34 has moved to the upper limit position (locking position). Is slightly pulled inside the front frame 3.

A wide portion 34w is formed near the center of the back side claw member 34, and a connecting member 38 is connected to the lower right end side of the wide portion 34w in a state in which it can be turned up and down by a turning pin 38p.
The connecting member 38 connects the front claw member 32 and the back claw member 34 and is engageable with a lock member 50 described later, and is formed in a substantially L-shaped side surface by a vertical portion 38k and a horizontal portion 38y. ing. The lower side of the connecting portion between the vertical portion 38k and the horizontal portion 38y of the connecting member 38 is connected to the wide portion 34w of the back side claw member 34 so as to be rotatable by the rotating pin 38p.
The connecting member 38 is formed with a flange 38t that engages with the lock member 50 at the left end of the vertical portion 38k, and a receiving portion 38e on which the operation handle 32r of the front claw member 32 is hung from the top at the tip of the horizontal portion 38y. Is formed. In addition, a spring receiver 38b on which the third spring 43 is hung is formed at the right end of the vertical portion 38k of the connecting member 38.

  The locking member 50 is a member that stops sliding in the unlocking direction (downward direction) of the back claw member 34 by engaging with the flange 38t of the connecting member 38, and is shown in FIGS. 2 (A) and 2 (B). As described above, the vertical lever 54 and the horizontal lever 52 are formed in a side L-shaped shape. The upper end of the vertical lever 54 of the lock member 50 is connected to the guide plate 18 of the fixed base frame 15 so as to be rotatable by a rotation pin 54p. The locking member 50 is provided with a stepped portion 52d at the base end portion of the lateral lever 52. When the locking member 50 rotates left about the rotating pin 54p and reaches the right limit position, the stepped portion is provided. 52d becomes engageable with the collar part 38t of the connection member 38 (refer FIG. 2 (B)).

At the upper right end of the vertical lever 54 of the lock member 50, a spring receiver 54b on which the third spring 43 is hooked is formed. The third spring 43 is biased in a direction to draw the spring receiver 54b of the lock member 50 and the spring receiver 38b of the connecting member 38 together. For this reason, the connecting member 38 and the back claw member 34 are pulled up to the upper limit position (locking position) by the third spring 43, and the lock member 50 is rotated clockwise by the spring force, and the step 52d of the lock member 50 is moved to the guide plate. 18 is held at a position (left limit position) that contacts the 18 ridges 18c (see FIG. 2A).
As shown in FIG. 4, the lateral lever 52 of the lock member 50 protrudes from the opening 3 e of the front frame 3, so that the stepped portion 52 d of the lock member 50 is opened with the glass frame 5 opened. The step 52d of the lock member 50 and the flange 38t of the connecting member 38 are held in a non-engaged state as shown in FIG. 3A.

Further, when the glass frame 5 is closed, the step 52d of the lock member 50 moves to the right limit position against the spring force of the third spring 43 by pressing the tip of the lateral lever 52. The step 52d engages with the flange 38t of the connecting member 38 as shown in FIG. For this reason, even if the back-side claw member 34 is illegally slid in the unlocking direction (downward), the locking member 50 and the connecting member 38 prevent the back-side claw member 34 from sliding downward.
However, in this state, when the front claw member 32 is pushed down by the second unlocking piece 23b of the cylinder lock 22, the operation handle 32r of the front claw member 32 pushes down the receiving portion 38e of the connecting member 38, and the connecting member 38 Rotates right about the rotation pin 38p. As a result, the flange portion 38t of the connecting member 38 is disengaged from the stepped portion 52d of the lock member 50, and the connecting member 38 and the back side claw member 34 together with the front side claw member 32 resist the spring force of the third spring 43, and the unlocking direction. Slide down (downward). Thereby, the engagement between the second engagement claw 35 and the second claw support 8 of the glass frame 5 is released, and the glass frame 5 is unlocked.

Next, the operation of the locking device 10 of the pachinko machine 1 will be briefly described.
The glass frame 5 is locked automatically by closing the glass frame 5. That is, by closing the glass frame 5, the second receiving metal fitting 8 of the glass frame 5 comes into contact with the third inclined surface 35 d of the second engagement claw 35 (see FIG. 2A), and the third inclined surface. 35d and the 2nd receiving metal fitting 8 slide. Due to this sliding action, the second engagement claw 35 receives a pressing force from the second metal fitting 8, and the back side claw member 34 including the second engagement claw 35 moves downward against the force of the third spring 43. Slide. Then, the second engagement claw member 30 of the third spring 43 is in a state in which the second receiving metal member 8 of the glass frame 5 is detached from the third inclined surface 35 d of the second engagement claw 35 and reaches the V-shaped groove 35 v. The second engagement claw 35 is hung on the second metal fitting 8 by sliding upward with force. Thereby, the glass frame 5 is locked.
Further, in the state where the glass frame 5 is locked (the state where the glass frame 5 is closed), the stepped portion 52d of the lock member 50 and the collar portion 38t of the connecting member 38 are engaged with each other. Even if the member 34 is illegally slid in the unlocking direction (downward), the downward sliding of the back claw member 34 is prohibited. For this reason, it is difficult to establish an illegal act.

The glass frame 5 is unlocked by the key operation of the cylinder lock 22. That is, when the cylinder lock 22 is operated by key operation and the unlocking lever 23 is turned to the left in FIG. 1A, the second unlocking piece 23b of the unlocking lever 23 is moved to the second engaging claw member 30 (front side). The engaging protrusion 36 of the claw member 32) is pushed down.
As a result, the front claw member 32 slides downward, and the operation handle 32r of the front claw member 32 pushes down the receiving portion 38e of the connecting member 38. As a result, the connecting member 38 rotates to the right about the rotating pin 38p, and the flange portion 38t of the connecting member 38 is disengaged from the step portion 52d of the lock member 50. It slides in the unlocking direction (downward) against the spring force of the third spring 43 together with the member 32. Thereby, the engagement between the second engagement claw 35 and the second claw support 8 of the glass frame 5 is released, and the glass frame 5 is unlocked.
Furthermore, when the back side claw member 34 slides downward, the first inclined surface 35u of the second engagement claw 35 slides with respect to the second metal fitting 8 of the glass frame 5, and the second metal fitting 8 is moved. Press in the opening direction of the glass frame 5. As a result, the glass frame 5 is opened to some extent simultaneously with the unlocking of the glass frame 5, and when the second engagement claw member 30 returns to the locking position by the force of the third spring 43 at the end of the unlocking, the second engagement The trouble that the nail | claw 35 gets on the nail | claw holder 8 of the glass frame 5 again does not arise.
In the state in which the front frame 3 is opened, it is also possible to unlock the glass frame 5 by directly pushing down the operation handle 32r of the front claw member 32 by hand.

As with the case of the glass frame 5 described above, the table frame 3 is locked automatically with respect to the machine frame 2 by closing the table frame 3.
In a state where the front frame 3 is locked, for example, when the lower first engaging claw 20 receives a force in the unlocking direction (upward rotation direction) by a special tool, the first engaging claw 20 is unlocked. While rotating in the direction, the lower plate 29 of the first engagement claw member 25 slides upward. However, even if the lower plate 29 of the first engaging claw member 25 slides upward, the lower pin 29p of the lower plate 29 only moves upward in the lower longitudinal elongated hole 28d of the central plate 28, and both 29p, 28d does not engage. For this reason, the rotational force of the first engagement claw 20 is not transmitted to the central plate 28 of the first engagement claw member 25. Therefore, the center plate 28 of the first engagement claw member 25 is held at the lower limit position, and the upper first engagement claw 20 is also held at the lower limit position by the force of the first spring 41. That is, even if the lower first engaging claw 20 is unlocked illegally, the upper first engaging claw 20 is held in the locked position, and thus the front frame 3 cannot be opened.

  Similarly, even if the upper first engagement claw 20 is unlocked illegally, the rotational force of the first engagement claw 20 is not transmitted to the central plate 28 of the first engagement claw member 25, so The first engaging claw 20 is held in the locked position. Therefore, the table frame 3 cannot be opened. That is, in order to open the front frame 3 illegally, the upper and lower first engaging claws 20 must be unlocked simultaneously with a special tool, so that an illegal act is difficult to be established.

  The table frame 3 is unlocked by operating the key of the cylinder lock 22. That is, the cylinder lock 22 is operated by key operation and the unlocking lever 23 is rotated to the right in FIG. 1A, so that the first unlocking piece 23 a of the unlocking lever 23 is centered on the first engaging claw member 25. The engaging protrusion 26 of the plate 28 is pushed up. As a result, the lower pin 29p of the lower plate 29 and the upper pin 27p of the upper plate 27 are pushed up by the lower end surfaces of the upper vertical hole 28u and the lower vertical hole 28d of the central plate 28. It slides upward against the force of the first spring 41 and the second spring 42. As a result, the upper and lower first engaging claws 20 pivot upward (rotate leftward in FIGS. 1 and 3) around the first lock pin 20p. The first frame 7 is removed and the front frame 3 is unlocked.

  As described above, according to the locking device 10 of the pachinko machine according to the present embodiment, the first engagement claw member 25 and the second engagement claw member 30 (front side claw member 32) are substantially heavy. Since they are arranged on the front side of the guide plate 18 so as not to be aligned, the plate surfaces of the first engagement claw member 25 and the front side claw member 32 are unlocked when the glass frame 5 or the front frame 3 is unlocked. There is no rubbing. That is, since there is almost no sliding resistance between the first engaging claw member 25 and the front claw member 32, the sliding resistance does not increase with time, and the malfunction of the locking device 10 is prevented. can do.

Moreover, since the back side claw member 34 provided with the engagement claw 35 for locking the glass frame is disposed on the back side of the guide plate 18, between the contour vertical line R of the front frame 3 and the guide plate 18 as in the prior art. It is not necessary to arrange the engaging claw 20 for locking the front frame and the engaging claw 35 for locking the glass frame within a narrow range, and the degree of freedom when arranging the engaging claws 20 and 35 is improved.
Further, when the front claw member 32 is operated in response to the operation of the cylinder lock 22, the operation of the front claw member 32 is transmitted to the back claw member 34 by the connecting member 38, and the back claw member 34 is moved in the unlocking direction. Slide. However, when the front claw member 32 does not operate, the back claw member 34 can be stopped from moving in the unlocking direction by the action of the lock member 50. Therefore, for example, the back side claw member 34 is not moved in the unlocking direction by an unauthorized operation, and the crime prevention performance is improved.

It is the front view (A figure) and side view (B figure) of the locking device of the pachinko machine concerning Embodiment 1 of the present invention. It is a disassembled side view of a locking device. It is a disassembled side view of a locking device. It is a front perspective view of the pachinko machine provided with the locking device concerning Embodiment 1 of the present invention.
