Description

  The present invention relates to a game board clamping device for detachably fixing a game board in a gaming machine such as a pachinko machine.

  A game board in a gaming machine such as a pachinko machine needs to be removed at the time of maintenance and inspection, or at the time of repair or minor change of the board surface, and is detachably fixed to the front frame of the gaming machine.

  Conventionally, as this type of fixture, a game board in which a rotation-type fixture having a locking portion rotatably provided is attached to a game board mounting frame provided so as to surround an edge of the game board. A fixing tool is proposed in Patent Document 1 below. This type of game board fixing tool first fits the game board inside the game board mounting frame, then turns the locking part about 90 degrees, and presses the edge of the game board by the locking part to fix it. Used to be.

Japanese Patent Laid-Open No. 11-179019 JP 2005-168679 A

  However, with this type of conventional game board fixing tool, when fixing the game board, first, while lifting the game board, it is inserted into the game board mounting frame inside the front frame, and the game board in that state is further inserted. While holding with one hand, rotate the locking part of the fixture with the other hand, press the edge of the game board with the locking part, and by the spring force of the spring member that urges the locking part The locking part is pressed against the edge of the game board and fixed.At this time, the locking part rotates while pressing the game board by a spring force, so the frictional resistance at the time of rotation is large. While holding the game board with one hand, it is necessary to turn the locking part of the fixing tool with the other hand, so that workability is poor, and depending on the locking condition of the locking part, fixing is likely to be incomplete. There was a problem.

  Also, when unlocking the game board and releasing it, while holding the game board with one hand, turn the locking part of the rotating fixture with the other hand to release the fixation. The game board is pulled out from the inside of the game board mounting frame with an edge, but the game board does not have a grip part like a handle, and depending on the operator, the game board can be used by holding the decorative part of the board as a substitute for the handle. In order to pull out, there exists a possibility that the decoration part may be soiled or damaged, and the workability of the work of removing the game board is poor.

  On the other hand, Patent Document 2 proposes a game board fixture having another structure. In this game board fixing tool, two fixed shafts are supported on the upper and lower portions of both side plates of the fixed member fixed to the front frame, and the operation member can be swung on the upper fixed shaft via a link plate. The coupling member having a clamp recess for fitting the edge of the game board is swingably supported on the lower fixed shaft, and the fitting member and the operation member are connected to the link plate. The fitting member is connected by a movable shaft different from the movable shaft, and is configured to bias the fitting member in the fitting direction and the opening direction by a torsion coil spring attached to the movable shaft and the fixed shaft.

  However, this game board fixing tool is configured such that the edge portion of the game board is fitted to the fitting member while swinging the operation member and the fitting member via the four shafts of the two fixed shafts and the two movable shafts. Because the structure is similar to a so-called multi-axis hinge that rotates so as to fit in the recess of the game board, when the edge of the game board is pushed into the clamp recess of the fitting member and clamped, the operation member and the fitting member smoothly When it is difficult to rotate, the rotation of the operation member and the fitting member stops halfway during clamping, and the edge of the game board is fitted in the recess of the fitting member with the clamping operation being insufficient However, there is a problem that an operator needs to push the fitting member by hand or to manually rotate the operation member to the open side.

  The present invention solves the above-described problems, and provides a game board clamping device capable of smoothly clamping a game board to a fixed part such as a game board fixing frame without looseness and unclamping with good workability. The purpose is to provide.

That is, as shown in FIG. 9, the lock member 4 inserts the edge portion of the game board 30 into the insertion space 17 of the holding member 3, presses the edge portion against the pushing portion 16, and rotates the holding member 3 to the clamp position. When moved, the locking hook portion 21 is locked to the locking pin 6 so that the clamping member 3 is locked at the clamp position.

  That is, as shown in FIG. 7, the lock member 4 is formed by bending a metal plate so as to have a substantially portal shape when viewed from the front, and has a grip portion 22 projecting on the front side at the upper portion. Locking hook portions 21 are formed on both sides of the lower portion so as to be able to be inserted into the holding plates 11 and 12 of the holding member 3 and to be locked to the locking pin 6. Further, the outer peripheral surface 23 of the locking hook portion 21 of the locking member 4 is pressed with a relatively small spring force against the locking pin 6 of the clamping member 3 as shown in FIG. 3 when in the unlocked (opened) state. Thus, it has a structure biased by the leaf spring 5.

  Thereby, when the clamping device is in the open state, the outer peripheral surface 23 of the locking hook portion 21 causes the locking pin 6 of the clamping member 3 to be connected to the leaf spring 5 with the clamping portion 10 of the clamping member 3 opened. Since it presses with a slight spring force and is made still at a fixed position, it can wait for an open state without generating rattling in the holding member 3 in an open state. That is, the upper part of the leaf spring 5 is in the open state of FIG. 3 and urges the lock member 4 upward by the spring force of FIG. 3, the outer peripheral surface 23 of the locking hook portion 21 of the locking member 4 is pressed to the left in FIG. 3 against the urging force of the leaf spring 5, whereby the clamping member 3 is rotated clockwise in FIG. 2. The locking pin 6 is inserted into the locking hook portion 21 of the locking member 4 and locked, and the clamping member 3 is locked in the clamping posture as shown in FIG.

  Further, as described above, the clamping member 3 is fixed by sandwiching both sides of the resin base 13 made of synthetic resin with the metal holding plates 11, 12, and a part of the resin base 13 protrudes forward as the grip 14. Therefore, it is easy to grip the clamping member 3 during unclamping, and the clamping member 3 of various thicknesses can be manufactured at a low cost according to the user's request.

  Next, the operation of the game board clamping device 1 having the above-described configuration will be described. As shown in FIG. 11, the clamp device 1 is fixed to a predetermined position of a game board fixing frame 31 attached in the front frame of the pachinko gaming machine using a fixing portion 2a of the base member 2 and a fixing screw. . As shown in FIG. 11, a rectangular notch is formed in the upper and lower portions of the right edge of the game board 30, and a pair of game board fixing frames 31 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 clamping part 10 of the clamping member 3 facing downward) and upward at the lower part (the clamping part 10 of the clamping member 3 facing upward). The clamping part 10 and the pushing part 16 of each clamping device 1 are attached so as to protrude from the game board fixing frame 31 toward the game board 30 and can be clamped.

  The left end portion of the game board 30 is rotatably held by the side end holding portion 32 within a certain range. The side end holding portion 32 is formed by bending a leaf spring, for example, and is formed so that the left end of the game board 30 can be fitted into the recess of the side end holding portion 32 while generating spring elasticity.

  When the game board 30 is attached to the game board fixing frame 31, first, the left end thereof is fitted into the recess of the side end holding part 32 while generating spring elasticity, and the right edge of the game board 30 is set to a certain extent. Hold it so that it can rotate.

  In this state, the right end of the game board 30 is lightly pushed into the insertion space 17 of the clamping member 3 of the clamping device 1 in the open state.

  At this time, as shown in FIG. 9A, the right end of the back surface or the front surface of the game board 30 first hits the pushing portion 16 of the sandwiching member 3, and when the sandwiching member 3 is pushed upward in FIG. The member 3 rotates about the pivot 7 in the clockwise direction of FIG. At this time, as shown in FIG. 9B, the locking pin 6 in the clamping member 3 pushes the outer peripheral surface 23 of the locking hook portion 21 of the locking member 4, so that the locking member 4 is slightly rotated clockwise. Move. 9 (c) to 9 (d), when the locking pin 6 exceeds the tip of the locking hook portion 21, the lock member 4 is rotated counterclockwise by the spring force of the leaf spring 5. It rotates to return to its original position, and the locking pin 6 is inserted into the locking hook portion 21 and locked. In this state, the edge of the game board 30 is connected to the clamping portion 10 of the clamping member 3 and the leaf spring. The pinching member 3 is completely pinched between the five spring pinching portions 5 a and the pinching state of the pinching member 3 is locked by the lock member 4.

  In this way, the edge portion of the game board 30 is simply inserted into the fitting space 17 of the clamping member 3 of the clamping device 1 in the open state, and the clamping member 3 is simply rotated so as to push in the pushing portion 16. By operation, the edge part of the game board 30 can be clamped and the game board 30 can be fixed with respect to the game board fixed frame 31 which is a to-be-fixed part. In the case of the game board fixing frame 31 shown in FIG. 11, the clamping device 1 is fixed to the upper and lower parts of the right end portion thereof, and it is extremely easy to push the right end portion of the game board 30 into the upper and lower clamping devices 1. The upper and lower portions of the right end of the game board 30 can be clamped with only one action. Further, the edge portion of the game board 30 is firmly held between the spring holding portion 5a of the leaf spring 5 and the holding portion 10 of the holding member 3, and the holding hook portion 21 of the lock member 4 is engaged in the holding state. Since the retaining pin 6 is locked and firmly held, even if a load is applied to the game board 30 in the removing direction, it will not come off.

  On the other hand, when the clamping device 1 is opened, as shown in FIG. 10A, the gripping portion 14 of the clamping member 3 and the gripping portion 22 of the lock member 4 are sandwiched between the thumb and the index finger, and the like in FIG. Thus, the clamping member 3 is slightly rotated counterclockwise, and the lock member 4 is slightly rotated clockwise. At this time, as shown in FIG. 10C, when the locking pin 6 moves from the inner side to the outer side of the locking hook portion 21 and exceeds the tip of the locking hook portion 21, as shown in FIG. In addition, the end of the locking hook portion 21 of the locking member 4 is in a state of pressing the locking pin 6 downward in the drawing, and the clamping member 3 is rotated to the fully opened position as shown in FIG. A part of the convex portion inside the both side walls 2c of the base member 2 comes into contact with and stops. At this time, the edge portion of the game board 30 is pushed forward by the pushing portion 16 of the holding member 3 and released.

  In this state, the clamping member 3 of the clamping device 1 that is in the open state has its locking pin 6 pressed against the outer peripheral surface 23 of the locking hook portion 21 of the locking member 4 and is stationary without rattling. The state of FIG. 10D is held by the urging force of the leaf spring 5, and each member is held without rattling. Therefore, when the edge of the game board 30 is clamped to the clamp device 1 again, the insertion space 17 of the clamping member 3 of the clamp device 1 in the open state is used as described above. The edge portion of the game board 30 can be clamped by a simple operation of inserting the inside and smoothly rotating the holding member 3 so as to push in the pushing portion 16.

  In the above embodiment, as shown in FIG. 11, the clamp device 1 is fixed downward on the upper part of the game board fixing frame 31, 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 30) to the upper and lower parts of the game board fixing frame 31 for use. In addition, as described above, the position of the game board fixing frame 31 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.
