Description

  The present invention relates to a holder for a locking device used in a locking device for a game machine such as a slot machine or a pachinko machine, and in particular, the locking of the holder in a groove-like latch recess of a latch member pivotally supported. The present invention relates to a receiving device for a locking device that locks a portion so as to be fitted.

Conventionally, as a locking device for a game machine such as a pachinko machine or a slot machine, a substantially egg-shaped latch member provided with a groove-like latch recess is used instead of a claw-like hook member protruding from the inside of the front frame. The latch member is pivotally supported on the support plate of the frame body, and the latch member is rotated while the latch pin fixed to the body frame side is fitted into the latch recess of the latch member, and the latch member projects. A locking device that locks and locks the latch member by engaging the engaging portion of the latch member with the provided locking convex portion is known from Patent Document 1 below.
Japanese Patent No. 3087024

  In this locking device, when the front frame to which the locking device is attached is locked to the main body frame to which the receiving metal fitting is fixed, the front frame is closed with respect to the main body frame so that the latch member of the locking device is received on the main body frame side. At this time, the latch member is rotated while fitting the latch pin into the latch recess of the metal fitting, and when the opening of the latch recess rotates to the inner latch position, The locking recess is engaged with the engaging portion of the latch member to lock and lock.

  However, since this type of locking device is locked when the locking pin is fitted into the latch recess of the latch member, the engagement between the locking pin and the latch recess is smoothly performed and can be locked smoothly. However, when the locking device is fixed inside the front frame of the actual game machine and the bracket is fixed at the corresponding position inside the main body frame at the manufacturing and assembly stage of the game machine, the latch member and the bracket of the locking device If the vertical and vertical positions of the locking pins do not match exactly, proper locking cannot be performed, and the locking / unlocking operation cannot be performed smoothly.

  For this reason, at the time of manufacturing and assembly, the height position and front / rear position of the metal fitting are adjusted so that an appropriate locking state can be obtained and the locking / unlocking operation can be performed smoothly. In the case of a metal fitting fixed by caulking of a portion, adjusting the inclination of the locking pin causes a rattling of the locking pin, and it is difficult to largely adjust the angle of the locking pin.

  For this reason, the accuracy of the mounting position of the locking device and the bracket will be very high. However, since the member for fixing the locking device and the bracket is a plywood in a normal game machine, the accuracy of the mounting position is increased. There is a problem that it is difficult to increase greatly due to workability problems during assembly work. Further, a pair of latch members are normally pivotally supported on the upper and lower parts of the base frame body of the locking device, and locking pins project from the upper and lower parts of one receiving metal fitting. For this reason, the subject that the attachment position of each locking pin cannot be adjusted independently occurred.

  The present invention solves the above-described problem, and in a locking device pivotally supporting a latch member having a groove-like latch recess, the latch member is smoothly fitted into the latch recess and locked. An object of the present invention is to provide a receiving device for a locking device that can easily adjust the position of a locking portion.

  The receiving bracket of the locking device according to the present invention pivotally supports a latch member provided with a groove-shaped latch recess to the support plate of the base frame body, and is placed in a corresponding position in the latch recess of the latch member. In a receiving device of a locking device that locks and locks the latch member in the latch position by turning the latch member while fitting the locking portion of the fixed receiving device, a part of the mounting portion of the metal plate is bent. In this form, a plate-shaped locking core portion is formed, and the synthetic resin covering portion covers at least the edge of the locking core portion from the base side of the locking core portion. The synthetic resin covering portion is formed with a substantially cylindrical columnar portion at a portion covering the edge of the locking core portion.

  Here, the cylindrical portion is formed on both sides of the synthetic resin covering portion, and the synthetic resin covering portion sandwiches the edge of the locking core portion from both sides and covers one surface of the locking core portion. The synthetic resin coating is formed in a shape and is fitted by sliding from the base side of the locking core, and comes into contact with the bending tip or the large-diameter tip of the locking core and stops. It can be constituted as follows.

  According to the holder of the locking device having the above configuration, a part of the mounting portion made of metal plate is bent to form a plate-like locking core portion, and the synthetic resin coating portion is locked to the locking core portion. It is fitted in a form that covers at least the edge of the locking core from the base part side of the core, and the synthetic resin coating has a substantially cylindrical column at the location covering the edge of the locking core. Synthetic resin with good lubricity when the cylindrical portion of the synthetic resin covering portion is fitted into the latch recess of the latch member provided in the locking device, and the latch member is rotated to lock and lock. The cylindrical portion of the cover-made covering portion can be smoothly fitted into the latch recess of the latch member and can be locked smoothly.

  In addition, when assembling the game machine, the locking device is attached to the inside of the front frame of the game machine and the support is fixed to the corresponding position in the main body frame, but the mounting accuracy of these fixed positions is relatively rough. Even so, the locking core part of the locking part of the receiver is formed by bending the metal plate with respect to the mounting part. The position of the cylindrical portion of the synthetic resin coating to be worn can be easily adjusted back and forth or up and down to ensure an appropriate locking state, and can be adjusted so that locking and unlocking operations can be performed smoothly.

  Furthermore, the synthetic resin covering portion is fitted from the base side of the locking core portion so as to cover the edge portion of the locking core portion, and is configured to stop at the bending tip portion or large diameter tip portion of the locking core portion. Then, in a state where the mounting portion of the receiving device is fixed to the cabinet side, it is impossible to remove the synthetic resin coating portion to the base portion side, and the synthetic resin coating portion that is easily fitted to the locking core portion can be removed. The fitted state can be maintained permanently.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a front view, a side view, and a plan view of a receiver 1 used in a locking device of a game machine, and shows a perspective view of the receiver 1 of FIGS. The receiver 1 is basically formed by providing locking portions 3 and 4 on the upper and lower portions of a vertically long strip-shaped metal plate, and a portion of the strip-shaped metal plate is formed as a mounting portion 2. A plurality of fixing holes 9 are formed, and the right side surface of the mounting portion 2 is fixed to the inside of the cabinet of the game machine.

  The upper and lower locking portions 3 and 4 are formed by cutting a part of the belt-shaped metal plate into a rectangular shape and bending it at a substantially right angle on the front side to form locking core portions 5 and 6. As shown in FIG. 4, the synthetic resin coating 10 covers the edges of the locking cores 5 and 6 from the base side of the locking cores 5 and 6 on the upper and lower locking cores 5 and 6. It is configured by fitting in the form. The distal ends of the locking core portions 5 and 6 formed in a rectangular plate shape by a metal plate are bent at a substantially right angle on the back side to form bent distal end portions 5a and 6a. Further, as shown in FIG. 4 and the like, recessed portions 5b and 6b for insertion are formed at the base portions of the upper and lower edge portions which are bent portions of the locking core portions 5 and 6, and the synthetic resin covering portion 10 is formed at the original portion.

  Although the cylindrical part 11 of the synthetic resin covering part 10 is formed on both the upper part and the lower part, a latch concave part of a latch member, which will be described later, is located on the lower side and is locked to the lower cylindrical part 11 when locked. Since the latch concave portion of the member is fitted and locked, the cylindrical portion 11 of the synthetic resin covering portion 10 may be only the lower portion. On the other hand, in the case of the synthetic resin covering portion 10 having the cylindrical portions 11 on both the upper and lower sides, the receiving member can be used in common for the locking device in which the latch member is inserted from above the engaging portion of the receiving member. . Further, when the synthetic resin covering portion 10 is inserted from the base side of the locking core portions 5 and 6, the insertion tip abuts against the bending tip portions 5a and 6a of the locking core portions 5 and 6, and stops. Although it was set as the structure which carries out, the bending front-end | tip part of the front-end | tip of the latching core parts 5 and 6 can also be stopped as a large diameter front-end | tip part.

  As shown in FIG. 4, the synthetic resin covering portion 10 is fitted to the locking core portions 5 and 6 so that the edge portion is inserted into the groove portion 12 from the right side surface side of the mounting portion 2 of the receiving device 1. Since the right side of the mounting portion 2 is fixed to the mounting portion inside the cabinet of the game machine, the receiving device 1 is fixed with the synthetic resin coating 10 after the receiving device 1 is fixed to the cabinet. The base portions of the inserted locking core portions 5 and 6 are closed, and the synthetic resin coating portion 10 is not removed.

  A stepped portion 7 with a step is formed on the front side along the longitudinal direction on the mounting portion 2 of the receiver 1 to improve the bending strength of the mounting portion 2. In addition, a sliding support plate 8 is provided at a position directly above the upper locking portion 3 of the mounting portion 2, and the support roller of the locking device rolls on the sliding support plate 8 when closing the front door of the game machine. And support the front frame.

  In addition, although the said receiver 1 formed the latching | locking part 3 in the upper part and the lower part of the one long attachment part 2, it isolate | separates an attachment part up and down and forms a latching part in each attachment part You can also Moreover, although the said synthetic resin coating | coated part 10 formed the cylindrical part 11 in the up-and-down both sides, a cylindrical part can also be provided only in one side of the side corresponding to the latch member of a locking device.

  Next, with reference to FIG. 8 to FIG. 15, a locking device main body corresponding to the receiver 1 will be described. FIG. 8 shows a left side view (a), a right side view (b), a rear view (c), and a plan view (d) of the locking device main body for the slot machine. The locking device main body pivotally supports latch members 40, 40, which are locked to the locking portions 3, 4 of the receiver 1, so as to be rotatable on upper and lower portions of the support plate 33 via pivots 35, 35. Then, the cylindrical portions 11 of the locking portions 3 and 4 are fitted into the latch recesses 45 and 45 of the latch members 40 and 40, and are locked by being locked.

  The locking device main body has a vertically long base frame body 31, which is formed in a channel material shape having a substantially U-shaped cross section, whose bottom plate is a mounting plate 32, and is perpendicular to the mounting plate 32. A wide support plate 33 is bent, and a plurality of mounting holes are formed in the mounting plate 32. A widened portion 32a is formed wide at the upper end portion of the mounting plate 32, an insertion hole for attaching the cylinder lock 37 is formed in the widened portion 32a, and the cylinder lock 37 is inserted into the insertion hole from the inside, The flange 37a is fixed to the inside of the widened portion 32a. The support plate on the side of the widened portion 32a is divided and formed as a divided support plate 33a, and a support roller 52 is rotatably supported on the lower portion of the divided support plate 33a.

  Opening recesses 33b and 33c are formed on the back side of the upper and lower portions of the support plate 33 so as to cut out a part of the support plate 33, and latched at positions just below the upper and lower opening recesses 33b and 33c, respectively. The members 40, 40 are pivotally supported around a pivot 35, 35 in a predetermined angle range. When the latch members 40 and 40 are locked, the locking portions 3 and 4 of the receiving device 1 enter the opening recesses 33b and 33c, and the latch member 40 pivotally supported just below the opening recesses 33b and 33c is locked. The cylindrical portions 11 of the portions 3 and 4 are received and rotated and locked. Further, as shown in FIG. 9, guide locking holes 38 and 38 for guiding and locking the locking pin 44 on the latch member 40 side are respectively provided slightly below the upper and lower opening recesses 33b and 33c. 33 is formed.

  The guide locking holes 38 and 38 are formed in an approximately L shape as shown in FIG. 9, and the portions parallel to the support plate 33 are formed as lock portions 38a and 38a, and the locking pins 44 of the latch members 40 and 40 are provided. When the guide holes 42a and 42a of the cover plate 42 are moved and simultaneously entered into the lock portions 38a and 38a from the guide locking holes 38 and 38, the latch member 40 is latched and locked.

  Further, support convex portions 39, 39 are provided on the support plate 33 slightly above the upper and lower guide locking holes 38, 38 so as to protrude inward, that is, on the latch members 40, 40 side. As shown in FIG. 11 b, the support protrusions 39, 39 enter an arcuate engagement recess 42 b formed on the inner surface of the latch member 40 and abut against the spring member 43. As a result, the latch member 40 rotates against the urging force of the spring member 43 at the time of locking, as shown in FIG. 15, and the locking pin 44 comes off from the lock portion 38a of the guide locking hole 38 at the time of unlocking. Then, the latch member 40 is rotated in the unlocking direction by the urging force of the spring member 43.

  As shown in FIG. 11, the latch member 40 is formed with a groove-like latch recess 45 that receives and restrains the locking portions 3, 4 of the receiver 1, and the latch member 40 has a latch member 40. A latch pin 44 and a spring member 43 for energizing are latched. Further, as shown in FIG. 11, the latch member 40 is formed having a latch main body 41 and a cover plate 42 covering the latch main body 41, a space is formed in the latch main body 41, and a spring member 43 is formed in the internal space. The locking pin 44 is stored.

  The latch body 41 is formed using a hard synthetic resin having high wear resistance such as polyacetal resin or polyamide resin, and the cover plate 42 is formed using a metal plate for reinforcement. A lubricant such as molybdenum disulfide is added to the molding material for molding the latch body 41, and thereby, the latch body 41 that forms the outer surface of the latch member 40 has an appropriate slipperiness, so The cylindrical portions 11 of the locking portions 3 and 4 are smoothly inserted. In addition, the strength of the latch member 40 is reinforced by fixing a metal plate cover plate 42 to the inner surface of the latch body 41.

  When the latch member 40 is rotated to the latch position, the latch pin 44 built in the latch member 40 is locked to the lock portion 38a of the guide latch hole of the support plate 33 at that position. The guide plate 42 is formed so as to protrude from the guide hole 42 a formed in the cover plate 42 toward the support plate 33, and is always urged outward by the spring member 43.

  As shown in FIG. 11, the spring member 43 is a torsion spring having a torsion shape. The spring member 43 urges the locking pin 44 at one end and a support convex portion 39 protruding from the inside of the support plate 33 at the other end. The annular portion at the center is externally fitted to the pivot 35 of the latch member 40, and the small annular portion is externally fitted to a convex portion provided at a biased position in the latch body 41. A support convex portion 39 on the support plate 33 side enters and engages with an arcuate engagement concave portion 42b formed in the cover plate 42 of the latch member 40, and the other end of the spring member 43 in the latch member 40 is engaged. The support protrusion 39 is engaged. That is, when the other end of the spring member 43 is engaged with the support convex portion 39, the latch member 40 is biased by receiving a spring force relative to the unlocking side (clockwise in FIG. 15).

  As shown in FIG. 11, the latch member 40 is unitized by incorporating a spring member 43 and a locking pin 44 therein, and the locking pin 44 and the spring member 43 are incorporated into the latch body 41 to fix the cover plate 42. It can be fixed with screws and manufactured in advance before the assembly process of the locking device. Thereby, in the production line of the locking device, it is only necessary to pivotally support the latch member 40 with the pivot 35, and the assembling work is simplified.

  A vertically long and belt-like operating rod 34 is slidably disposed along the outside of the support plate 33 and the inside of the divided support plate 33a of the base frame 31. As shown in FIG. 9, the operation engagement portion 34 a and 34 b are provided on the operation rod 34 at the upper and lower portions thereof so as to protrude toward the support plate 33 and toward the latch member 40, and the latch members 40 and 40. The locking pins 44, 44 are inserted into the locking portions 38a, 38a of the guide locking holes 38, 38, and when unlocked, the locking pins 44, The latch is released by pushing 44. The operating engagement portions 34a and 34b are arranged inside the operating rod 34 and the outside thereof is covered with a metal plate, and slightly protrude outside the support plate 33 through the guide locking holes 38 and 38. This is a structure that acts on the tips of the locking pins 44, 44.

  In addition, the operating rod 34 is formed with engaging holes 34c and 34d for engaging a cam member 51 described later at the upper part corresponding to the holes. Further, guide holes 34g and 34g are formed immediately below the operation engagement portions 34a and 34b of the operating rod 34, and the guide pins 36 and 36 are inserted into the guide holes 34g and 34g and fixed to the support plate 33. Thus, the vertical sliding of the operating rod 34 is guided by the guide pins 36 and 36.

  The operating rod 34 is disposed along the outside of the support plate 33 and along the inside of the divided support plate 33a, and the operating rod 34 is supported in a floating state by a single spring member (coil spring) 46, and is predetermined. It is possible to move up and down with a width of.

  Specifically, as shown in FIG. 9, guide pins 46 c and 46 d are inserted from the inside of the support plate 33 through guide holes 33 d and 33 e provided in the support plate 33. Further, the distal ends of the guide pins 46c and 46d are inserted into the guide holes 34f and 34e of the operating rod 34 positioned outside the support plate 33, and spring latching members 46a and 46b are respectively protruded from the distal ends of the operating rod 34 protruding outside. The spring member 46 is hung between the spring latching members 46a and 46b on both sides. As a result, the operating rod 34 can move upward and downward from the neutral position in FIG. 8 against the urging force of the spring member 46, and the operating rod 34 is moved upward by the rotation of the cam member 51 by the cylinder lock 37. Alternatively, after moving downward, the structure returns to the neutral position when the moving force disappears.

  Further, the operating rod 34 is used both for unlocking operation and for switching operation, and a switch operating portion 34e is projected near the lower portion of the operating rod 34. On the other hand, a function switch (photoelectric non-contact switch) 47 is attached to the support plate 33 corresponding to the switch actuating portion 34e. When the actuating rod 34 is lowered, the switch actuating portion 34e becomes the function switch 47. Acts to turn the function switch 47 on and off. This function switch 47 is used to reset the game machine.

  In this way, by using the unlocking operating rod 34 for both unlocking operation and switch operation, the conventionally required operating rod for the operation switch and the coil spring for biasing it are unnecessary, The number of parts can be reduced and the structure of the locking device can be simplified.

  As shown in FIG. 10, a large-diameter hole is formed in the widened portion 32a on the upper portion of the mounting plate 32 of the base frame 31, and the cylinder lock 37 is mounted in such a manner that the large-diameter hole is inserted from the inside. The cylinder lock 37 has a flange 37 a and is fixed by screwing the flange 37 a to the widened portion 32 a of the mounting plate 32. The lock shaft of the cylinder lock 37 protrudes to the inside of the base frame 31, and the cam member 51 is fixed to the tip thereof. The cam member 51 is formed with a first engagement convex portion 51 a and a second engagement convex portion 51 b, and the first engagement convex portion 51 a is actuated according to the clockwise rotation of the key of the cylinder lock 37. The second engaging convex portion 51b can be engaged with the engaging hole 34c according to the left rotation.

  Therefore, when the key of the cylinder lock 37 is turned to the right, the cam member 51 is rotated, the engagement convex portion 51a of the cam member 51 is engaged with the engagement hole 34d of the operating rod 34, and the spring member 46 is attached. The operating rod 34 is lifted against the force, and the latch pins 40 and 40 are unlocked by pushing up the locking pins 44 of the latch members 40 and 40 by the operating engagement portions 34a and 34b. On the other hand, when the key of the cylinder lock 37 is turned counterclockwise, the cam member 51 rotates and the engagement convex portion 51b of the cam member 51 engages with the engagement hole 34c to resist the biasing force of the spring member 46. Then, the operating rod 34 is lowered, and the switch operating portion 34e enters the function switch 47 to turn the switch on and off.

  Further, a second cylinder lock 49 is mounted on the back side of the mounting plate 32 in the upper part of the base frame body 31. A lock member 48 is fixed to the lock shaft of the second cylinder lock 49, and the distal end portion of the lock member 48 enters the inside of the base frame body 1 from the slit provided in the widened portion 32 a of the mounting plate 32, and the cam member 51 is inserted between the operating rod 34 and the movement of the operating rod 34 in the unlocking direction due to the rotation of the cam member 51 is prevented.

  The lock member 48 of the second cylinder lock 49 prevents only the movement of the operating rod 34 to the unlocking side, and the operating rod 34 can move in the switch operating direction (downward). When the cam member 51 is rotated in the switch operating direction, a long hole into which the engaging protrusion 51b can enter is formed, and the cam member 51 can be rotated in the same direction.

  In this way, when the unlocking operation of the cylinder lock 37 is locked and unlocked, the unlocking operation is performed with the second key of the second cylinder lock 49, and then the unlocking operation of the cylinder lock 37 is further performed. The security is further improved by unlocking. The second cylinder lock 49 is fixed to an attachment seat portion 32b protruding from the upper back side of the attachment plate 32, and the keyhole of the second cylinder lock 49 is arranged facing the left side surface of the locking device body.

  As shown in FIG. 12, the locking device main body having the above-described configuration is fixed vertically inside the front door 21 of the game machine via a mounting plate 32, and the receptacle 1 is attached to a facing position in the cabinet 20. The keyhole of the cylinder lock 37 of the locking device body is exposed on the front surface of the front door 21, and the keyhole of the second cylinder lock 49 is exposed on the upper right side of the front door 21.

  When the front door 21 is closed with respect to the cabinet 20, as shown in FIGS. 12 and 13, the upper and lower engaging portions 3 and 4 of the receiving device 1 are latched from the upper and lower opening recesses 33b and 33c of the locking device main body. The members 40 and 40 enter the latch recesses 45 and 45. At this time, as shown in FIG. 14, the cylindrical portion 11 of the synthetic resin covering portion 10 of the locking portions 3 and 4 pushes the latch members 40 and 40, so that the latch members 40 and 40 are counterclockwise as shown in FIG. When the latch members 40 and 40 are rotated to the rotation end, the locking pin 44 in the latch member 40 is moved in the guide locking hole 38 by the urging force of the spring member 43, thereby The locking pin 44 enters the lock portion 38 a of the guide locking hole 38.

  At this time, the rotation of the latch members 40 and 40 is locked, and the latching portions 3 and 4 of the receiver 1 are restrained in the latch recesses 45 and 45 of the latch members 40 and 40 as shown at the left end of FIG. The latch members 40, 40 are held in the latch position, and are locked (FIG. 13). At the time of such locking, as described above, the cylindrical recess portion 45 of the latch member 40 and the cylindrical portion 11 of the synthetic resin covering portion 10 of the receiving device 1 fitted therein are made of a synthetic resin having appropriate lubricity. Since it is molded, it can be locked very smoothly and the unlocking operation can be performed smoothly. In addition, the use of the synthetic resin latch member 40 having good wear resistance and the receiver 1 reduces the wear of the contact / contact portion and allows the latch member and receiver to operate stably over a long period of time. Can do.

  When unlocking the front door 21, first, a key is inserted into the second cylinder lock 49 and turned, and the lock member 48 of the lock shaft is turned counterclockwise in FIGS. 12 and 13, and the cam member 51 is rotated by the lock member 48.
