  Furthermore, the assembly body of the said unclamp member 8 and the clamp member 3 is assembled | attached inside the base member 2 through the 1st pivot 11, so that rotation is possible. The first pivot 11 is attached to both side walls near the lower portion of the base locking portion 14 in the lower part of the base member 2 so as to span in the horizontal direction. On the back side of the base member 2, a back wall that is continuous with both side walls is formed.

  As shown in FIGS. 4 and 5, the clamp member 3 is formed in a shape in which a metal clamp side plate 4 is fixed on both sides of a synthetic resin clamp body 5 and the side surface is substantially U-shaped. As shown in FIG. 8, the first pivot 11 is pivotally supported by the first pivot 11 with respect to the base member 2. The clamp body 5 is formed in a shape having a substantially L-shaped side surface by a synthetic resin, and an elastic piece 6 having spring-like elasticity is provided on the upper portion thereof so as to protrude obliquely toward the unclamp member 8 side.

  The elastic piece 6 urges the clamping locking portion 16 of the unclamping member 8 to press the base locking portion 14 against the base locking portion 14 as shown in FIG. Along with the rotation about the second pivot 12, it acts to bias the clamp member 3 to the open side. Since the elastic piece 6 is integrally formed at the time of molding the clamp body 5 made of synthetic resin, the number of parts does not increase and the number of assembling steps does not increase at the time of assembly.

  In addition, as shown in FIG. 4, the clamp body 5 is provided with two through holes 5a and 5b, and a fixing pin 13 is inserted into the through hole 5b through the through holes of the clamp side plates 4 and 4 on both sides. The clamp body 5 is sandwiched between the two clamp side plates 4 and 4 by the fixing pin 13. Further, as shown in FIG. 4, the first pivot 11 is inserted through the other through hole 5a. The clamp side plates 4 and 4 fixed so as to sandwich both sides of the clamp body 5 are provided with through holes 4b and 4c at positions corresponding to the through holes 5a and 5b.

  Further, as shown in FIG. 4, a through hole 4 d is provided in the upper part of the clamp side plates 4 and 4 on both sides, and the second pivot shaft 12 that pivotally supports the unclamp member 8 is inserted into the through hole 4 d. Furthermore, an arcuate protrusion 4a is provided at one lower part of the clamp side plates 4 and 4 on both sides. The arcuate protrusion 4a is in contact with the edge of the game board when clamping, and the edge of the game board via the arcuate protrusion 4a when the clamp member 3 rotates when unclamping. Acts to extrude.

  Moreover, as shown in FIG. 1, the bulging curved surface part 5c is provided in the clamp body 5 made of synthetic resin on the open side of the clamping part 3b of the clamp member 3 in a form protruding from the clamp side plates 4 and 4. . The bulging curved surface portion 5c made of synthetic resin acts to smoothly guide the edge of the game board when the edge of the game board is fitted into the clamping portion 3b of the clamp member 3 and is clamped. The corners of 4 and 4 do not hit the game board and are not damaged, and it is possible to eliminate problems during clamping due to dimensional error of each member.

  The unclamping member 8 is formed in a lever shape with a substantially L shape in a side view, and a substantially circular operation portion 8a is provided at the tip thereof. The operation portion 8a is operated to be pulled obliquely upward from the front with a finger or the like. The In addition, a shaft hole 8 b is provided at a substantially central portion thereof, and the unclamp member 8 is pivotally supported with respect to the clamp member 3 through the shaft hole 8 b and the second pivot shaft 12. In other words, the unclamp member 8 is positioned in the clamp member 3 as shown in FIG. 4, and the second pivot 12 is inserted into the shaft hole 8b from the through holes 4d of the clamp side plates 4 and 4 on both sides, and the unclamp The member 8 can be rotated within a predetermined angle range about the second pivot 12. Further, the unclamp member 8 pivotally supported by the second pivot 12 with respect to the clamp member 3 in this way is urged in the clockwise direction in FIG. 4 by the elastic piece 6. In addition, although the unclamp member 8 is shape | molded with a metal, it can also shape | mold with a hard synthetic resin.

  Further, on the upper surface of the unclamping member 8, as described above, an opening locking portion 15 as a trough (concave portion) and a clamping locking portion 16 are formed on both sides of the peak portion 17. The locking portion 16 is locked to the base locking portion 14 to maintain the clamped state. When the unclamping member 8 is opened, the clamping locking portion 16 is locked to the base as the unclamping member 8 rotates. The clamp member 3 and the unclamp member 8 are pivoted to the open side, and the release locking portion 15 is locked to the base locking portion 14 so that the open state is maintained. .

  As shown in FIG. 4, the unclamping member 8 is inserted inside the upper portion of the clamping member 3, and the second pivot 12 is inserted into the through holes 4 d and the shaft holes 8 b of the clamp side plates 4, 4 on both sides. It is pivotally supported with respect to the base. In this state, as shown in FIG. 4b, the tip of the elastic piece 6 comes into contact with the lower surface of the unclamp member 8, and the unclamp member 8 is urged and assembled by the elastic piece 6 in the clockwise direction of FIG. It becomes.

  Such an assembly of the clamp member 3 and the unclamp member 8 is assembled by being inserted inside the base member 2 to which the leaf spring member 7 is attached, as shown in FIG. That is, the assembly of the clamp member 3 is inserted inside the base member 2, and the first pivot 11 is connected to the shaft hole 2 b in a state in which the through holes 4 b and the shaft holes 2 b provided at both lower portions of the base member 2 are combined. Are inserted into the through hole 4b and the shaft hole 5a and assembled.

  When the assembly of the clamp member 3 is assembled to the base member 2, as shown in FIG. 10, it can be assembled with almost no urging force by the elastic piece 6 if it is assembled in an open state rather than a clamped state. . In this case, while the shaft hole 2b, the through hole 4b, and the shaft hole 5a are combined, the first locking shaft 11 is placed in the holes while the release locking portion 15 of the unclamp member 8 is applied to the base locking portion 14. The clamping device can be easily assembled by inserting it.

  Next, the operation of the gaming board clamping device 1 having the above-described configuration will be described. As shown in FIG. 13, the clamp device 1 has an inner side surface of a corner portion of the game board fixing frame 21 attached in the front frame of the pachinko gaming machine (a surface entering one step from the surface of the game board 20 to the back side). The base member 2 is fixed using a fixing piece 2a and a fixing screw. As shown in FIG. 13, a rectangular notch is formed in the upper and lower portions of the right edge of the game board 20, and a pair of game board fixing frames 21 corresponding to the square notch is provided at the upper and lower positions. The clamping device 1 is fixed downward at the upper part (with the sandwiching part 3b facing downward) and upward at the lower part (with the sandwiching part 3b facing upward). The clamping portion 3b of each clamping device 1 is attached so as to protrude from the game board fixing frame 21 to the game board side so as to be clamped.

  The left end portion of the game board 20 is rotatably held by the side end holding portion 22 within a certain range. The side end holding portion 22 is formed, for example, by bending a leaf spring, and is formed so that the left end of the game board 20 can be fitted into the recess of the side end holding portion 22 while generating spring elasticity.

  When the game board 20 is attached to the game board fixing frame 21, first, the left end thereof is fitted into the recess of the side end holding part 22 while generating spring elasticity, and the right edge of the game board 20 is set to a certain extent. Hold it so that it can rotate.

  In this state, the right end of the game board 20 is lightly pushed into the holding opening 3a of the clamp device 1 in the open state as shown in FIG.

  At this time, as shown in FIG. 11, the right end of the back surface of the game board 20 first hits the arcuate protruding portion 4 a of the clamp member 3, and the clamp member 3 is pushed to the back side, with the first pivot 11 as the center. It rotates clockwise in FIG. Further, when the arcuate protrusion 4a of the clamp side plate 4 of the clamp member 3 receives a pressing force from the game board 20, the assembly of the clamp member 3 and the unclamp member 8 is the first pivot 11 as shown in FIG. Further, the contact position of the base locking portion 14 that contacts the opening locking portion 15 of the unclamp member 8 is the left inclined surface from the opening locking portion 15 at this time. It reaches mountain part 17 after that.

  At this time, as shown in FIG. 11, the front surface of the edge of the game board 20 hits the holding part 3 b and fits into the holding opening 3 a, and the arcuate tip 7 a of the leaf spring member 7 is inserted into the game board 20. It contacts the back of the edge. When the edge of the game board is fitted into the holding opening 3a of the clamp member 3, the bulging curved surface part 5c smoothly guides and clamps the edge of the game board. It won't hurt by hitting the board. In this way, the edge of the game board 20 enters between the arcuate tip 7a of the leaf spring member 7 and the clamping part 3b of the clamp member 3, and is almost clamped.

  Further, when the contact position between the base locking portion 14 and the unclamping member 8 exceeds the mountain portion 17, the edge of the game board 20 is further fitted into the holding opening 3a as shown on the left side of FIG. The edge of the game board 20 is firmly clamped between the arcuate tip 7a of the leaf spring member 7 on the back side and the clamping part 3b of the clamp member 3.

  And finally, the base latching | locking part 14 fits into the trough part of the clamping latching | locking part 16 of the unclamp member 8, and a clamp is completed. In this state, the clamp member 3 that holds the edge portion of the game board 20 and is pivotally supported around the first pivot 11 has the unclamp member 8 abutting the clamping locking portion 16 against the base locking portion 14. Therefore, the rotation about the first pivot 11 is completely locked, and the clamped state is firmly held.

  Thus, the edge of the game board 20 is inserted into the clamping opening 3a of the clamp member 3 of the clamp device 1 in the open state, and the game board 20 can be rotated by a simple operation by simply turning it. The game board 20 can be fixed to the game board fixing frame 21 which is a fixed part by clamping the edge. In the case of the game board fixing frame 21 shown in FIG. 13, the clamping device 1 is fixed to the upper part and the lower part of the right end part thereof, and it is very simple that only the right end part of the game board 20 is pushed into the upper and lower clamping apparatuses 1. The upper and lower portions of the right end of the game board 20 can be clamped with only one action.

  Further, even when the edge of the game board 20 accidentally hits the tip of the unclamp member 8 of the clamp device 1 during the clamping operation of the game board 20 as shown in FIG. Since the opening locking portion 15 is in contact with the base locking portion 14 and is locked, the unclamping member 8 and the clamping member 3 do not rotate clockwise in FIG. Therefore, even when the edge of the game board 20 accidentally hits the tip of the unclamping member 8, the clamping device 1 is prevented from malfunctioning.

  Further, when the edge portion of the game board 20 is inserted into the holding opening 3a of the clamp member 3 of the clamp device 1 in the open state and rotated so as to push the clamp member 3, the game board 20 has a certain reason. When it is desired to return the clamping operation, if it is in the state shown on the right side of FIG. 11, that is, if the peak portion 17 of the unclamping member 8 is within the range that does not exceed the base locking portion 14, the clamping operation is easily released. The clamping operation is very easy.

  On the other hand, when opening the clamp apparatus 1, the operation part 8a of the front side edge part of the unclamp member 8 is pulled forward as shown in FIG. At this time, the unclamp member 8 is slightly rotated counterclockwise in FIG. 12 about the second pivot 12, and the clamping locking portion 16 of the unclamping member 8 is separated from the base locking portion 14. The contact portion of the locking portion 14 passes over the mountain portion 17 via the inclined surface.

  At this time, since the user holds the operation portion 8a and rotates it counterclockwise in FIG. 12, when the contact portion of the base locking portion 14 passes the slope portion 17 via the inclined surface, the clamp member 3 The assembly of the unclamp member 8 is rotated counterclockwise in FIG. 12 about the first pivot 11 by the urging force of the elastic piece 6, and finally the clamp member 3 is the uppermost stage in FIG. Thus, the game board 20 is released from the clamp. At this time, since the edge of the game board 20 is pressed to the open side by the spring force of the leaf spring member 7, the edge of the game board 20 is automatically pushed forward and released. It becomes.

  Thus, when the game board 20 is removed, the unclamping member 8 of the clamping device 1 is operated to the open side to disengage the clamping locking portion 16 from the base locking portion 14. 3 and the unclamping member 8 are urged so that the operating force and the spring force of the elastic piece 6 rotate to the open side and the edge of the game board 20 is pushed out by the leaf spring member 7. The game board 20 can be detached from the game board fixing frame 21 by a simple operation of simply pulling 8 forward.

  Further, when the unclamping member 8 of the clamping device 1 is operated to the open side to disengage the clamping locking portion 16 from the base locking portion 14, the operation of the unclamping member 8 is performed as shown in FIG. If the rotation range of the portion 8 a is within a certain range, that is, if the base locking portion 14 is within the range until it exceeds the peak portion 17 of the unclamp member 8, the unclamp member 8 is attached to the elastic piece 6. Since it returns to the clamped state due to the force, it is possible to prevent a problem that the clamp is accidentally opened.

  In the above embodiment, as shown in FIG. 13, the clamp device 1 is fixed downward on the upper part of the game board fixing frame 21, and another clamp device 1 is fixed upward on the lower part. As described above, the clamp device 1 can be fixed laterally (horizontally toward the edge of the game board 20) to the upper and lower parts of the game board fixing frame 21 and used. Further, as described above, the position of the game board fixing frame 21 for fixing the clamp device 1 is fixed to the clamp device 1 downward as the upper side portion of the frame, or clamped as the lower side portion of the frame, as described above. It is also possible to use the apparatus 1 while being fixed upward.
