Description

  The present invention relates to a pachinko machine in which a handle for launching a game ball is provided so as to be rotatable.

  In general, a pachinko machine is provided with a launching device for launching a game ball and a handle for operating the launching device. The handle is provided so as to protrude forward from the pachinko machine, and when the player rotates the lever member of the handle, the launching device operates and a game ball is launched. Further, the launch strength of the game ball can be adjusted by adjusting the rotation amount of the lever member. Furthermore, a return means such as a return spring that biases the lever member in a direction to return the lever member to the initial rotation position is provided in the handle, and when the player releases the lever member, the lever member is initially rotated. It is designed to automatically return to the moving position.

  Here, when the player continues the game for a long time, it can be considered that the hand gets tired or the like and the hand is released from the lever member. However, in the above pachinko machine, the lever member automatically returns to the initial rotation position when the hand is released, so when resuming the game, the lever member is rotated again to find a suitable rotation position. As a result, a lot of useless balls are generated, which may give an unpleasant feeling to the player. For this reason, a pachinko machine has been devised in which the lever member can be maintained at a predetermined rotational position even if the hand is released.

  For example, in the pachinko machines described in Patent Documents 1 and 2, when a button is provided on the handle and the button is pushed in when the lever member is at a predetermined rotation position, the lever member is maintained at the rotation position. It is configured as follows. Further, in the pachinko machine described in Patent Document 3, a ring-shaped member is interposed between a lever member to be rotated and a cover member fixed to the front end of the handle, and the lever is caused by the frictional force of the ring-shaped member. The member is configured to be maintained at a predetermined rotation position.

Japanese Utility Model Publication No. 60-31753 No. 7-42459 JP 2004-337435 A

  However, in the configurations described in Patent Documents 1 and 2, a mechanism (for example, a switch locking portion) for preventing automatic return must be provided inside the handle, and there is a problem that the structure of the handle becomes complicated. is there. Further, the configuration described in Patent Document 3 has a problem that the contact surface between the lever member and the ring-shaped member is easily damaged because a frictional force always acts even when the lever member is rotated.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a pachinko machine in which the structure of the handle is not so complicated and the handle and the fixing member are not damaged.

In order to achieve the above object, the invention according to claim 1 of the present invention is provided with a handle provided with a pivotable lever member, and has a launch strength according to the pivot position of the lever member. A pachinko machine that launches a game ball and is provided with a fixing member for fixing the lever member at an arbitrary rotational position to the handle, and the fixing member is a release that does not normally fix the lever member The lever member is in a position, and in response to a predetermined operation, the lever member is pressed in a radial direction around the rotation shaft, and the lever member is fixed by a frictional force generated between itself and the lever member. Features.
The invention according to claim 2 is the invention according to claim 1, wherein the handle includes a cylindrical main body and the lever member attached so as to cover the outer peripheral surface of the front end portion of the main body in a non-contact manner. A portion of the lever member that covers the outer peripheral surface of the main body in a non-contact manner is formed into a wavy shape that is uneven in the radial direction, and a wide width is provided between the inner peripheral surface of the lever member and the outer peripheral surface of the main body. While the first gap and the narrow second gap are provided, the fixing member is a ring-shaped body made of a synthetic resin having elasticity, and is thinner on the front surface than the first gap and thinner than the second gap. A thick fixing protrusion is provided, and the fixing member is located at a position rearward of the lever member at the front end of the main body and the fixing protrusion is positioned in the first gap. And can be rotated to launch game balls. When the lever member is rotated to adjust the degree, the fixing member is also rotated in synchronism, and only the fixing member is rotated when the lever member reaches a desired rotation position. Then, the lever member can be fixed by inserting the fixing protrusion into the second gap.
The invention according to claim 3 is the invention according to claim 2, wherein the outer peripheral surface of the fixing member is formed in a wave shape with the same pitch as the lever member, and the fixing member is in the release position. The phase of the waveform of the fixing member is synchronized with the phase of the waveform of the lever member.

According to the present invention, the lever member is normally in a release position where the lever member is not fixed, and in response to a predetermined operation, the lever member is pressed in the radial direction around its rotation axis, and between the lever member and itself Since the fixing member that fixes the lever member by the generated frictional force is provided, even if the hand gets tired or the seat is removed by fixing the lever member with the fixing member, the same launch strength when restarting the game Thus, it is possible to launch game balls, to reduce the number of useless balls when the game is resumed, and to prevent the player from feeling uncomfortable. Further, the lever member is not rotated while the frictional force is applied, and wear and damage of the lever member and the fixing member can be prevented. Furthermore, since the structure in which the lever member is directly pressed and fixed by the fixing member is adopted, the structure can be configured without providing a complicated fixing mechanism inside the handle, and the structure related to fixing / releasing of the lever member can be simplified. It can be realized with a simple structure.
According to the second aspect of the present invention, the lever member can be fixed only by rotating the fixing member, and the direction in which the fixing member is rotated with respect to the lever member in a fixed state. By simply applying a load in the same direction, the fixing protrusion is automatically pushed out into the first gap by its own elasticity, and the lever member can be released from being fixed. Therefore, the operation relating to the fixing / releasing of the lever member is simple, and the structure relating to the fixing / releasing of the lever member can be simplified.
Furthermore, according to the invention of claim 3, when the outer peripheral surface of the fixing member is formed in a wave shape having the same pitch as the lever member, and the fixing member is in the release position, the phase of the waveform of the fixing member and the lever Since the phase of the waveform of the member is synchronized, the player can naturally hold the fixed member when holding the lever member. Therefore, when the lever member is rotated to adjust the launch strength of the game ball, the fixing member can also be easily rotated. Therefore, only the lever member is rotated, and it is difficult to cause a situation in which the fixing protrusion enters the second gap and the lever member is inadvertently fixed although it is not intended, and the operability is good. .

  Hereinafter, a pachinko machine according to an embodiment of the present invention will be described in detail with reference to the drawings.

The volume member 35 is connected to the launching device 10 by a cable or the like (not shown), and the launching device 10 adjusts the launch strength of the game ball according to the rotation amount of the lever member 32 detected by the volume member 35. It has become. Reference numeral 16 denotes a stop button for stopping the launch of the game ball.

  The opening at the front end of the main body 31 is covered with a disc-shaped inner cover member 38 having irregularities (the inner cover member is also a constituent element of the main body in the claims). A shaft hole 39 is formed substantially at the center of the inner cover member 38, and a shaft portion 45 of the lever member 32, which will be described later, can be inserted therethrough. In addition, an accommodation recess 40 that can accommodate the return spring 17 for biasing the lever member 32 to the initial rotation position is formed around the shaft hole 39. Furthermore, a peripheral wall portion 42 extending rearward is provided on the outer peripheral portion of the inner cover member 38, and the inner cover member 38 has a rear surface of the peripheral wall portion 42 slightly outward from the outer peripheral surface of the main body 31. It is attached to the main body 31 so as to protrude. A fixing hole (not shown) through which a bolt for fixing the outer cover member 33 can be inserted is formed in the front surface of the inner cover member 38.

  Further, a fixing member 34 is externally provided at the distal end portion of the main body 31. The fixing member 34 is a ring-shaped body made of a synthetic resin having elasticity, and is fixed to the support step portion 41 formed on the outer peripheral surface of the main body 31 and the rear end portion of the peripheral wall portion 42 of the inner cover member 38. It is attached to the main body 31 so as to be rotatable in a sandwiched state. Further, the outer peripheral surface of the fixing member 34 is formed in a wave shape so that the player can easily perform the turning operation. Further, a plurality of fixing protrusions 60, 60... Project forward from the front surface of the fixing member 34. Each fixing protrusion 60 is provided at each position where the outer peripheral surface protrudes outward (hereinafter referred to as a crest position), and is positioned on the outer peripheral surface of the inner cover member 38 in the mounted state of the fixing member 34. . Further, both ends in the circumferential direction of each fixing protrusion 60 are chamfered and rounded. The position where the outer peripheral surface of the fixing member 34 is recessed inward is referred to as a valley position.

  Further, a lever member 32 for adjusting the launch strength of the game ball is attached in front of the inner cover member 38. The lever member 32 is hung from the outer peripheral edge of the flange portion 46 to the rear side, a shaft portion 45 provided substantially at the center, a flange portion 46 extending outwardly around the shaft portion 45, and the flange portion 46. The holding part 47 is formed integrally. The shaft portion 45 is provided so as to protrude forward and backward along the central axis, and the side protruding backward is inserted into the shaft hole 39 and connected to the volume member 35 via the connecting member 44. On the other hand, the side protruding forward of the shaft portion 45 is fitted into a bearing portion 52 of an outer cover member 33 described later, and a resin ring member 48 for smoothly rotating the lever member 32 is provided on the exterior. Is done. The flange portion 46 is formed with a slit 49 in an arc shape. A fixing protrusion for fixing the outer cover member 33 to the inner cover member 38 is inserted into the slit 49, and the fixing protrusion relatively moves in the slit 49 when the lever member 32 is rotated. Thus, the rotation of the lever member 32 is not hindered.

  In addition, the grip portion 47 is a portion that the player grips, and covers the outside of the inner cover member 38 when the lever member 32 is attached. The gripping portion 47 is formed in a wave shape that is uneven in the radial direction at the same pitch as the fixing member 34, and the gap (first gap) S <b> 1 between the peak position and the inner cover member 38 is wider than the fixing protrusion 60, A gap (second gap) S <b> 2 between the position and the inner cover member 38 is narrower than the fixed protrusion 60. The lever member 32 is attached to the main body 31 such that the fixed protrusion 60 is positioned in the gap S1. Therefore, as shown in FIG. 7, the crest position of the lever member 32 and the crest position of the fixing member 34 coincide with the trough position of the lever member 32 and the trough position of the fixing member 34 (that is, the phase of the waveform of both members). When the player grips the handle 9, the grip portion 47 and the fixing member 34 can be easily gripped together with one hand.

  In addition, an outer cover member 33 including a plate-like base portion 50 and a dome-like decorative portion 51 fixed to the base portion 50 is attached in front of the lever member 32. Near the center of the base 50, there is provided a bearing portion 52 into which a shaft portion 45 on which a resin ring member 48 is sheathed can be fitted.

It is fixed.

Here, the operation of the handle 9 configured as described above will be described.
When a player plays a game with the pachinko machine 1, the player holds the lever member 32 and the fixing member 34 together, and simultaneously turns both of them to start launching a game ball. In addition, after launching is started, the turning strength of the game ball is adjusted by adjusting the rotation amount of the lever member 32 so that the launch position of the game ball into the game area 2a becomes a desired position (at this time, The fixing member 34 is also rotated in synchronization with the lever member 32). When the game ball is launched to a desired position, as shown in FIG. 8, only the fixing member 34 is rotated to move the fixing protrusions 60, 60,... To the narrow gaps S2, S2,. Forcibly enter. Then, the fixed protrusion 60 presses the lever member 32 in the radial direction around the rotation axis, and friction generated between the outer peripheral surface of the fixed protrusion 60 and the inner peripheral surface of the lever member 32 causes the return spring 17 to move. The lever member 32 is fixed at the rotational position against the urging force. Therefore, even if the hand is released from the lever member 32, the game is not automatically returned to the initial rotation position, and the game can be resumed while the launch strength of the game ball is maintained only by gripping the lever member 32 again. Can do.

  Further, when it is desired to finely adjust the rotation position of the lever member 32 again, or when it is desired to return the lever member 32 to the initial rotation position when the game ends, the fixing member is fixed to the lever member 32 in the fixed state. What is necessary is just to apply a load in the same direction as the rotation operation direction related to fixing 34. Then, the fixing protrusions 60, 60,... Are pushed out of the gaps S2, S2,... Into the gaps S1, S1,. Therefore, the lever member 32 can be freely rotated, and the rotation position of the lever member 32 can be readjusted. When the lever member 32 is released, the lever member 32 is initially rotated by the biasing force of the return spring 17. It can be automatically returned to the position.

  According to the pachinko machine 1 having the handle 9 as described above, the handle 9 is provided with the fixing member 34 that presses and fixes the lever member 32 in the radial direction around the rotation axis thereof. After adjusting the rotation amount of the lever member 32 so that the ball is launched to a desired position, the lever member 32 can be maintained at the rotation position by operating the fixing member 34. Therefore, even if the hand gets tired or removes the seat, the lever member 32 does not automatically return to the initial rotation position, and the game ball can be launched with the same launch strength when the game is resumed. Therefore, the useless balls can be reduced when the game is resumed, and the player does not feel uncomfortable.

Further, according to the pachinko machine 1 having the handle 9, the lever member 32 can be fixed only by rotating the fixing member 34, while the fixing member 34 is fixed to the lever member 32. By simply applying a load in the same direction as the moving operation direction, the fixing protrusions 60, 60,... Are automatically pushed out into the gaps S1, S1,. Therefore, the operation relating to the fixing / releasing of the lever member 32 is simple, it is not necessary to provide a complicated mechanism or the like inside the handle 9, and the structure relating to the fixing / releasing of the lever member 32 can be a simple structure. it can.
Furthermore, since both ends in the circumferential direction of each fixing protrusion 60 are chamfered, when the fixing member 34 is rotated to fix the lever member 32, the fixing protrusion 60 easily enters the gap S2, and the fixing member 34 Therefore, it is possible to prevent a situation in which a considerable force is required for the pivoting operation of the rotating member, and it is possible to prevent the fixing protrusion 60 and the lever member 32 from being worn and damaged.

Furthermore, the outer peripheral surface of the gripping portion 47 of the lever member 32 and the outer peripheral surface of the fixing member 34 are formed into a waveform having the same pitch so that the phases of the waveforms of the lever member 32 and the fixing member 34 are synchronized. Since it is attached, the player can naturally hold the fixing member 34 when holding the lever member 32. Therefore, when the lever member 32 is rotated to adjust the launch strength of the game ball, the fixing member 34 can also be easily rotated. Accordingly, only the lever member 32 is rotated, and it is difficult to cause a situation in which the fixing protrusion 60 enters the gap S2 even though it is not intended, and the lever member 32 is inadvertently fixed. Is good.
In addition, in the handle 9 of the present embodiment, the fixing member 34 is normally in a release position where the lever member 32 is not fixed, and the lever member 32 is not rotated while the frictional force is applied. 32 and the fixing member 34 can be prevented from being worn or damaged.

  In addition, the structure which concerns on the handle | steering-wheel and pachinko machine of this invention is not limited to the aspect as described in the said embodiment at all, The shape and structure of a handle main body, a lever member, an outer cover member, a fixing member, the pachinko machine About a structure, it can change suitably as needed in the range which does not deviate from the meaning of this invention.

For example, the position and number of fixing protrusions provided on the fixing member can be changed as appropriate, and the lever member can be fixed as long as at least one fixing protrusion is provided over the entire circumference.
Further, the shape of the fixing protrusion is not limited to the above-described embodiment. The shape of the fixing protrusion is formed in a wedge shape in front view so as to gradually increase in thickness from one end to the other end in the circumferential direction, and the thin side leads to the gap S2. By being configured to enter and fix the lever member, it is possible to further facilitate the rotation operation of the fixing member when the lever member is fixed.
Furthermore, it is also possible to employ a configuration in which a protruding portion that protrudes further outward is provided on the outer peripheral surface of the fixing member without forming the outer peripheral surface of the fixing member into a wave shape. By adopting this configuration, the player can rotate the fixing member together with the lever member while pressing a finger or the like against the protrusion, and move the finger at a desired position to rotate only the fixing member. The lever member can be fixed. Therefore, the lever member can be fixed only with a hand holding the lever member, and the operability related to the fixing of the lever member can be further improved.
