Description

  The present invention relates to a gaming machine having a relatively heavy front door, and a game in which the front door is less likely to be caught by an operator during maintenance work of the gaming machine by braking the rotation when the front door is opened and closed. Related to the machine.

  A gaming machine called a pachislot usually has a plurality of reels each having a plurality of symbols arranged on the surface thereof, game medals and coins are inserted, a start lever is operated by the player, and rotation of the plurality of reels is performed. When a player detects that a start switch for requesting a start and a stop button provided for each of the reels have been pressed by the player, and an operation of the start lever is detected, a lottery is performed based on a random value. The reel rotation is stopped based on the result of the lottery and the timing at which the stop button is detected.

  A number of patent applications for this type of gaming machine have already been filed. For example, from Japanese Patent Application Laid-Open No. 2007-202698 and Japanese Patent Application Laid-Open No. 2010-29407, a housing having an opening on the front surface and a side surface of the housing are disclosed. It is known to include a front door that is movably connected to open and close this opening. In this type of gaming machine, a cylinder lock is installed in a housing, a key hole is provided on the front surface of the front door on the opening and closing side, and a key is inserted and rotated in the key hole to lock or unlock the front door.

JP 2007-202698 A JP 2010-29407 A Utility Model Registration No. 3184416

  For this type of gaming machine, opening and closing of the front door is necessary for daily maintenance, but there is no particular proposal regarding a hinge for opening and closing the front door. For example, Japanese Patent Application Laid-Open No. 2010-29407 includes a first lock mechanism and a second lock mechanism for locking and unlocking the front door, but there is no description regarding a hinge mechanism for opening and closing the front door. Therefore, even if the hinge used in this type of gaming machine is relatively large in order to support the weight of the front door, it can be estimated that the product is structurally similar to the conventional one.

  The front door is opened and closed in order to perform daily maintenance such as coin replenishment, and the front door itself is removed from the casing when the equipment is fully repaired or replaced. For this reason, the hinges used in this type of gaming machine usually consist of two sets of upper and lower insertion hinges composed of a vertical pin installed on the side wall of the housing and a horizontal plate installed on the front door side and having a pin hole perforated. (Refer to FIG. 1) It is also possible to install a vertical pin on the front door side, and a horizontal plate with a pin hole drilled on the side wall of the housing.

  In a gaming machine that can open and close the front door by attaching an existing insertion hinge, when the front door is opened and the employee is carrying out daily maintenance, the front door closes to a natural weight of nearly 20 kg. There are frequent accidents involving the fingers. The front door is not attached to the housing in a completely vertical direction, but the upper part of the front door is inclined back and forth by about 5 degrees, so that even if the door is opened, it closes naturally with its weight. Is a problem.

  The present inventor has already proposed Utility Model Registration No. 3184416 in order to remedy the above-mentioned problems related to a gaming machine having a heavy front door that is easy to close naturally. The rotary brake hinge used in the present invention is convenient for braking only in the opening direction of the front door, but becomes expensive to some extent because a one-way wheel, which is a precision instrument, is always used. In addition, since the inner diameter of the through hole provided in the barrel of the rotary brake hinge is substantially the same as the diameter of the pivot, when the pivot is inserted into the barrel through hole, the installation work of the heavy front door becomes somewhat longer.

  In order to improve the above-mentioned problems related to the opening and closing of the front door of the gaming machine, the present invention can brake the opening and closing of the front door by using at least one braking hinge having a relatively simple structure in the hinge mechanism. Even if it exists, it aims at providing the game machine whose cost increase is comparatively small. Another object of the present invention is to provide a gaming machine that is easily stopped when a pivot pivot of a braking hinge is inserted into a vertical hole of a leaf body.

  A gaming machine according to the present invention includes a housing having an opening on the front surface, a front door that is inclined to close the opening of the housing, and a hinge mechanism that detachably attaches the front door to the housing. Have. In this gaming machine, the hinge mechanism is composed of two insertion hinges in the vertical direction having vertical pins that can be inserted and removed, and at least one of the insertion hinges is a braking hinge, and the braking hinge is installed on the side wall of the housing. And a hinge body having a pivot pivot equivalent to a vertical pin, and a leaf body having a vertical hole into which the pivot can be inserted and installed on the front door side, and a protrusion on the pivot pivot side wall is a vertical hole of the leaf body When the front door is opened and closed, the pivot pivot is braked and rotated with respect to the hinge body.

  In another gaming machine according to the present invention, the hinge mechanism is composed of two insertion hinges in the vertical direction having vertical pins that can be inserted and removed, and a braking hinge is installed between both insertion hinges. The hinge body has a pivot body that is installed on the side wall and has a pivot pivot equivalent to a vertical pin, and a leaf body that is installed on the front door side and has a vertical hole into which the pivot can be inserted. When it is inserted into the vertical hole of the leaf body, it is locked by the concave portion of the vertical hole, so that when the front door is opened and closed, the rotation pivot is braked and rotated with respect to the hinge body.

  In the gaming machine of the present invention, the leaf body installed on the front door side may be integrated with a vertical frame attached along the rear vertical edge on the front door side.

  In the gaming machine of the present invention, it is preferable that the hinge main body of the brake hinge has a plastic brake cylinder body into which the pivot pivot is closely fitted and a bracket provided with a through hole for stationary accommodation of the brake cylinder body. The rotary pivot is press-fitted into the brake cylinder to hold it vertically so that it can be braked, and the bracket is bolted to the side wall of the casing.

  The hinge body of the brake hinge includes a plastic brake member that is closely fitted to the pivoting pivot, a holding bracket that surrounds the outer periphery of the brake member, and a bolt that passes through the parallel extension of the brake member and the holding bracket and is screwed into the bracket. You may have. With this bolt, the brake member is tightened inward with the holding metal to hold the pivot pivot vertically so as to be able to brake, and the bracket is bolted to the side wall of the casing.

  The hinge body of the brake hinge includes an L-shaped bracket having a horizontal portion provided with a through-hole that fits in the pivoting pivot, a plastic brake disc disposed adjacent to both side surfaces of the horizontal portion of the L-shaped bracket, and each brake You may comprise with the washer which contacts a disc and rotates or stops with a pivot. By fitting at least one disc spring with the pivot and tightening the entire hinge body with a nut, when the front door is turned, the surface of the brake disc and the surface of the washer become friction surfaces, and the vertical of the L-shaped bracket The part is bolted to the housing side wall.

  The gaming machine according to the present invention has a braking hinge attached to at least a part of the hinge mechanism to effectively brake when the front door is opened and closed, so that even if the door is opened, it closes naturally with its weight. It is possible to prevent accidents in which employees get their fingers caught in the front door during daily maintenance. In the gaming machine of the present invention, the front door itself can be removed from the housing as in the conventional case, so that it is naturally possible to repair or replace the entire device.

  The gaming machine of the present invention does not use an expensive one-way wheel, which is a precision instrument, and uses at least one braking hinge having a relatively simple structure as a hinge mechanism, so that opening and closing of the front door can be braked. However, the cost increase is relatively small. Further, in this brake hinge, since the pivot is easily stopped just by inserting the pivot into the vertical hole of the leaf body, the heavy front door does not go around when the pivot is inserted into the vertical hole of the leaf body. The mounting work is completed in a short time as in the prior art.

  The present invention will be described with reference to the drawings. A hinge mechanism 2 illustrated in FIG. 1 is used for detachably attaching a front door 7 to a housing 5 in a pachislot machine 1 (FIG. 2) as a gaming machine. In the hinge mechanism 2, one or both of ordinary insertion hinges 8 (FIG. 10) arranged separately in the vertical direction are replaced with the braking hinge 10. The normal insertion hinge 8 has a fixed vertical pin 4 that can be inserted and removed (see FIG. 10), and when the front door 7 is large and heavy, three or more can be installed. In FIG. 1, both of the two insertion hinges are replaced with braking hinges 10. The brake hinge 10 may be replaced with only one of the two insertion hinges, or may be separately provided between the two insertion hinges as shown in FIG.

  As illustrated in FIGS. 2 and 3, the gaming machine in the present invention means a so-called pachislot machine 1, and can also be applied to a normal pachinko machine that is not a pachislot machine or other game machines. A pachislot machine 1 that is an example of a gaming machine includes a housing 5 having an opening 3 (FIG. 3) on the front surface and a front door 7 that is inclined so as to close the opening of the housing. The front door 7 generally has a mode in which the opening 3 of the housing 5 is closed by a single sheet, and may have a structure in which the front door 7 is closed by two or three or more divided vertically.

  The pachi-slot machine 1 has, for example, a housing 5 that houses reels 11, 12, 13, a circuit board, and the like, and a front door 7 is attached to the housing 5 so that it can be opened and closed. The housing 5 may have a structure in which three reels 11, 12, and 13 are arranged in parallel in the lateral direction and these reels are installed on the front door. Each reel 11, 12, 13 affixes a belt-like sheet in which a large number of symbols are continuously arranged along the rotation direction on the peripheral surface of a cylindrical frame.

  A liquid crystal display body 14 is provided in the center of the front door 7, and the liquid crystal display body has a flat display screen including display windows 16, 18, and 20. When the front door 7 is closed, three liquid crystal display bodies 14 are viewed from the front. The reels 11, 12, and 13 are overlapped and arranged so as to be positioned on the front side. The display windows 16, 18, and 20 are arranged so as to correspond to the reels 11, 12, and 13, respectively, and have a structure that allows the reels 11, 12, and 13 located behind the reels to be seen through. The display windows 16, 18, and 20 function as symbol display windows, and the operations of rotating and stopping the reels 11, 12, and 13 behind are visible from the player side. The liquid crystal display 14 displays a video on the entire display screen including the display windows 16, 18, and 20 to produce a game.

  The display windows 16, 18, and 20 are the upper and middle stages in the frame from among a number of symbols arranged on the surface of each reel 11, 12, 13 when the rotation of the reels 11, 12, 13 behind is stopped. In the lower area, one symbol is displayed. Further, in each of the upper, middle, and lower areas of the display windows 16, 18, and 20, a pseudo line that combines any of the predetermined ones is defined as a winning determination line that is a target for determining whether or not to win. To do.

  On the other hand, the front door 7 is provided with each member that is a target of a game operation by the player. The medal slot 22 receives a medal dropped from the outside by the player. For example, medals inserted into the medal slot 22 are used in one game up to a predetermined number of three, and as a credit function, medals exceeding the predetermined number are stored in the pachislot machine 1. Can be deposited in The bet button 24 determines the number of coins to be inserted into one game from medals deposited inside the pachislot machine 1. The settlement button 26 pulls out medals deposited inside the pachislot machine 1 to the outside. The start lever 27 starts to rotate all the reels 11, 12, and 13. The stop buttons 28, 30, and 32 are associated with the reels 11, 12, and 13, respectively, and stop the rotation of the corresponding reels 11, 12, and 13.

  The hinge mechanism 2 shown in FIG. 1 generally includes a vertical frame 34 attached to the housing 5 side and a vertical frame 36 attached along the rear vertical edge on the front door 7 side. In the case of FIG. Are directly attached to the housing 5 and the front door 7. A hinge body 40 of the brake hinge 10 having a pivot pivot 38 is fixed to the vertical frame 34 on the housing 5 side at a predetermined interval in the vertical direction. On the other hand, a leaf body 42 integrated with the frame is formed on the vertical frame 36 on the front door 7 side so as to correspond to the hinge body 40. This hinge mechanism may be directly fixed to the housing 5 and the front door 7 without using the frames 34 and 36 as shown in FIG. Although not shown, a leaf body can be formed on the vertical frame 34 on the housing 5 side, and a hinge body of a brake hinge can be attached to the vertical frame 36 on the front door 7 side. It needs to be placed downward.

  Even if the vertical frames 34 and 36 are U-shaped in a cross section in FIG. 4 and a linear shape with a partial curve, both frames can be arbitrarily changed according to the shapes of the housing 5 and the front door 7. It is possible to arrange it closely to the housing 5 when closed. 4 shows a state in which the front door 7, that is, the vertical frame 36 is opened, and an alternate long and short dash line in FIG. 4 shows a state in which the front door 7, that is, the vertical frame 36 is closed. The illustrated vertical frame 36 is usually attached to the back side of the peripheral wall of the front door 7.

  The leaf body 42 shown in FIG. 1 forms a vertical hole 45 (FIG. 4) into which the pivot 38 can be inserted by the cylindrical portion 44 by bending a portion extending in the horizontal direction in the vertical frame 36 into a cylindrical shape. Further, the gap 46 corresponding to the pivot locking recess is present by not bending to a complete circle. The inner diameter of the vertical hole 45 is slightly larger than the diameter of the rotation pivot 38. Further, the leaf body is made of a member separate from the vertical frame 36, and the member can be bolted to the vertical frame 34. This leaf body may be constituted by a horizontal plate 48 (FIG. 10) or the like having a perforated vertical hole, and the vertical hole may be provided with a notch corresponding to a recess for pivot locking.

  5 to FIG. 8 show a press-fitting type, FIG. 11 and FIG. 12 are a clamping type, and FIG. 13 to FIG. 15 are a braking disc type, and any type can be applied to the present invention. 5 to 8, the hinge body 40 of the press-fit brake hinge 10 has, for example, a rectangular flat bracket 50 that holds the pivot pivot 38 vertically so as to be brakeable, and the planar shape of the bracket is arbitrary. . The bracket 50 is provided with a through-hole 52 (FIG. 8) in the vertical direction, and a brake cylinder 88 (FIG. 9) is fitted in the through-hole so as not to rotate, and the pivot 38 is press-fitted (see FIG. 8). As a result, the pivoting pivot 38 can be braked and rotated around the brake cylinder 88. On the other hand, as shown in FIGS. 6 and 7, a screw hole 54 is formed in the side wall of the bracket 50, and a bolt is screwed into the screw hole to fix the bracket 50 to the vertical frame 34 on the housing 5 side.

  The pivot 38 is preferably an elongated cylindrical shape, and its tip 57 is preferably processed into a conical shape so that it can be easily inserted into the vertical hole 45 of the leaf body 42. The rotating pivot 38 may be made of a single metal or may be integrated by inserting a metal shaft 58 into a hard resin plug 59 as shown in FIG. The rotary pivot 38 has a linear protrusion 60 formed on the peripheral wall thereof in parallel with the axis. The protrusion protrudes outward from the peripheral wall of the pivot 38, and the tip is tapered so as to be easily fitted into the recess of the vertical hole 45. Shape. Further, when the front door 7 is attached to the opening 3 of the housing 5, the hinge body 40 and the leaf body 42 are arranged so that the axis of the rotation pivot 38 easily coincides with that of the vertical hole 45 (FIG. 4). If necessary, even if an auxiliary plate having an appropriate thickness is stacked on the vertical frames 34 and 36, the side walls of the housing 5 and predetermined portions of the front door 7 are deformed into a convex shape without using such frames. May be.

  When inserting the pivot pivot 38, it is preferable that the protrusion 60 fits in the recess of the vertical hole 45, that is, the gap 46 of the cylindrical portion 44. Therefore, if the concave portion of the vertical hole 45 is the gap 46 of the cylindrical portion 44, the horizontal cross section of the protrusion 60 extends tangentially from the peripheral surface of the pivot 38 as shown in FIG. If the concave portion of the vertical hole 45 is a simple rectangular shape, the horizontal cross section of the protrusion 60 may be rectangular, and if the leaf body is the horizontal plate 48 (see FIG. 10), the protrusion 60 is also shortened accordingly. You can do it. When the pivot pivot 38 is inserted into the vertical hole 45 of the leaf body 42, the projection 60 is fitted and locked in the gap 46 of the cylindrical portion 44, so that the pivot pivot can be braked and rotated together with the leaf body 42.

  In the hinge mechanism 2, in FIG. 10, the brake hinge 70 is disposed between the normal insertion hinges 8 and 8. The normal insertion hinge 8 includes, for example, a vertically fixed vertical pin 4 installed on the side wall side of the housing 5 via a bracket 71 and a horizontal plate 48 installed on the front door 7 side and having a pin hole 64 drilled. Usually, the vertical portion 66 of the horizontal plate is bolted to the front door 7.

  When the brake hinge 10 is installed in the pachislot machine 1, the pivot pivot 38 rotates with the leaf body 42 when the front door 7 is opened and closed in the brake hinge, and the rotation of the pivot is braked by the hinge body 40. For this reason, the front door 7 is braked and rotated in any of the opening and closing directions, so that the pachislot machine 1 does not naturally close by its weight even when the front door 7 is opened, and daily maintenance is performed. Accidents in which employees get their fingers caught in the front door when performing When opening and closing the front door 7, it is necessary to apply some force in the opening and closing direction of the front door 7 so that the pivoting pivot 38 can be braked and rotated within the hinge body 40.

  In order to remove the front door 7 from the housing 5, the leaf body 42 is pulled out from the pivot pivot 38, and if necessary, the horizontal plate 48 is pulled out from the vertical pin 4 at the insertion hinge 8. The door 7 can be removed, and the pachislot machine can be completely repaired or replaced. On the other hand, in order to attach the front door 7 to the housing 5, the pivot pivot 38 is inserted into the vertical hole 45 of the leaf body 42 in the braking hinge 10, and the horizontal plate 48 is fitted to the vertical pin 4 in the insertion hinge 8 if necessary. When combined, the front door 7 can be easily attached to the opening 3 of the housing 5.

  Next, although this invention is demonstrated based on an Example, this invention is not limited to an Example. A pachislot machine 1 which is an example of a gaming machine according to the present invention has a hinge mechanism 2 shown in FIG. 1, which includes a vertical frame 34 attached to the housing 5 side and a rear vertical edge on the front door 7 side. And both the frames are made of metal. The hinge bodies 40 of the two brake hinges 10 are fixed to the vertical frame 34 on the housing 5 side at a predetermined interval in the vertical direction. On the other hand, a leaf body 42 integrated with the frame is formed on the vertical frame 36 on the front door 7 side so as to correspond to the hinge body 40.

  The leaf body 42 shown in FIG. 1 has a vertical hole 45 (FIG. 4) formed by a cylindrical portion 44 by bending a portion extending in the lateral direction in the vertical frame 36 into a cylindrical shape, and further bent to a complete circular shape. The absence of a pivot locking gap 46 is present. The part extending in the horizontal direction is spaced apart by a predetermined distance in the vertical direction corresponding to the position of the hinge body 40, and is actually positioned in the vicinity of the upper and lower ends of the vertical frame 36.

  The hinge body 40 of the press-fit brake hinge 10 shown in FIGS. 5 to 8 has a rectangular flat bracket 50 that vertically holds the pivot pivot 38 so as to be brakeable, and the bracket is made of glass fiber reinforced nylon. The bracket 50 is provided with a through-hole 52 (FIG. 8) in the vertical direction, and a brake cylinder 88 (FIG. 9) is fitted in the through-hole so as not to rotate, and the pivot 38 is press-fitted (see FIG. 8). As a result, the pivoting pivot 38 can be braked and rotated around the brake cylinder 88. 6 and 7, a screw hole 54 and two positioning projections 56, 56 are formed on the side wall of the bracket 50, and a bolt is screwed into the screw hole to attach the bracket 50 to the housing 5 side. It can be fixed to the vertical frame 34.

  The pivot 38 has an elongated cylindrical shape, and its tip 57 is processed into a conical shape so that it can be easily inserted into the vertical hole 45 of the leaf body 42. As shown in FIG. 8, the pivot 38 is integrated by inserting a metal shaft 58 into a plug 59 made of glass fiber reinforced nylon. The rotary pivot 38 has a linear protrusion 60 formed on its peripheral wall parallel to the axis, and the protrusion protrudes outward from the peripheral wall of the pivot 38 so that it can be easily fitted into the cylindrical portion 44 of the leaf body 42. Is tapered.

  The braking cylinder 88 shown in FIG. 9 includes a flange portion 90 and a cylindrical portion 92, and an axial key protrusion 93 is formed on the outer peripheral wall of the cylindrical portion. The outer diameter of the cylindrical portion 92 is substantially equal to the diameter of the through hole 52, and the inner diameter of the cylindrical portion is slightly smaller than the diameter of the rotating pivot 38 in a non-pressed state. Since the brake cylinder 88 is made of, for example, wear-resistant polyacetal, it can be used for a long time. When the brake cylinder 88 is housed in the through hole 52 from above, the key protrusion 93 provided in the axial direction engages with the key groove of the through hole 52 and is stationary, and the lower corner portion 94 of the flange portion 90 is stationary. Is closely in contact with the chamfered peripheral edge (not shown) of the through-hole 52, so that the brake cylinder 88 is completely fitted into the through-hole 52 except for the flange portion 90 and stops.

  The cylindrical portion 92 of the brake cylinder 88 has a length equal to or less than the depth of the vertical through hole 52. When the brake cylinder 88 is housed in the through hole 52, the flange portion 90 comes into contact with the lower surface of the collar portion 95 of the rotation pivot 38. When the pivoting pivot 38 is press-fitted through the braking cylinder 88, the pivot can be supported so as to be able to perform braking rotation. A disc-shaped washer 96 is fitted into the pivot 38, and the center hole of the washer is fitted to the deformed end of the pivot 38 to be caulked. The diameter of the washer 96 is larger than the inner diameter of the through-hole 52. Instead of the washer, a snap ring such as an E ring and a groove are formed, and the pivot 38 is prevented from coming out by screwing the ring.

  In FIG. 1, an upper portion of a rectangular leaf spring 68 is attached to the vertical frame 34 above the braking hinge 10, and the lower portion of the leaf spring is slightly inclined inward. At the time of attaching the front door 7, the cylindrical portion 44 of the leaf body 42 is fitted to the rotation pivot 38 of the hinge body 40, and the cylindrical portion descends while the peripheral wall presses the lower portion of the leaf spring 68. When the lower end wall comes into contact with the flange portion 95 of the pivoting pivot 38, the peripheral wall of the cylindrical portion 44 releases the pressure of the leaf spring 68, so that the lower portion of the leaf spring returns to its original position. As a result, even if the front door 7 is to be removed without permission, the leaf spring 68 prevents the cylindrical portion 44 of the leaf body 42 from moving up and down, so that it is possible to prevent fraud by preventing the front door 7 from being removed. In order to remove the front door 7, it is necessary to push the leaf spring 68 inward in advance.

  When the front door 7 is attached, when the cylindrical portion 44 of the leaf body 42 is fitted to the pivot pivot 38 of the hinge bodies 40, 40, the projection 60 fits closely into the gap 46 of the cylindrical portion 44, thereby the projection 60. Is inserted into and locked in the gap 46 of the cylindrical portion 44, and the pivoting pivot can be braked and rotated together with the leaf body 42. In the pachi-slot machine 1, the front door 7 can be detached from the housing 5, and when the front door 7 is opened and closed, the front door 7 is braked and rotated in any direction of opening and closing.

  FIG. 10 shows a modification of the hinge mechanism used in the present invention. This hinge mechanism is provided between the normal insertion hinges 8 and 8 having the vertical pins 4 that can be inserted and removed, and between the insertion hinges 8 and 8. The press-fit brake hinge 70 is installed. The insertion hinge 8 is composed of an upwardly fixed vertical pin 4 installed on the side wall side of the housing 5 via a bracket 62 and a horizontal plate 48 installed on the front door 7 side. Bolt the door 7. A circular pin hole 64 into which the vertical pin 4 can be inserted and removed is formed in the horizontal plate 48.

  The braking hinge 70 shown in FIG. 10 is similar to the braking hinge 10 shown in FIGS. In the brake hinge 70, the hinge body has a rectangular flat bracket 71 that vertically holds the pivot pivot 72 so that the pivot pivot 72 can be braked, and the pivot pivot can be braked and rotated around a brake cylinder in the bracket 71. Although not shown, a screw hole and two positioning protrusions are formed on the side wall of the bracket 71, and a bolt can be screwed into the screw hole to fix the bracket 71 to the housing 5 side.

  On the other hand, the leaf body 74, which is an independent member, includes a base portion 75 and a cylindrical portion 76. The cylindrical portion 76 is provided with a pivot locking gap (not shown) by bending the belt-like piece into a cylindrical shape so as to form a vertical hole 78 and not bending it into a complete circle. A plurality of bolt holes (not shown) are drilled in the base portion 75, and a predetermined bolt is screwed into the bolt hole to fix the leaf body 74 to the front door 7 side.

  The pivot pivot 72 has an elongated cylindrical shape, and its tip is processed into a conical shape so that it can be easily inserted into the cylindrical portion 76 of the leaf body 74. As in the first embodiment, the pivot pivot 72 is integrated by inserting a metal shaft into a glass fiber reinforced nylon plug. The rotary pivot 72 forms a straight protrusion 84 parallel to the axial line on the plug peripheral wall, the protrusion protrudes outward from the plug peripheral wall, and the tip is tapered so that the cylindrical portion 76 of the leaf body 74 can be easily fitted.
