[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hinge device that is disposed between a base member and an opening / closing member and connects the base member and the opening / closing member so as to be relatively swingable and openable.
[0002]
[Prior art]
The hinge device as described above is widely used in gaming machines, and an example thereof is a hinge device disposed between an outer frame and a front frame in a pachinko machine. A hinge device of a pachinko machine is composed of a pair of upper and lower hinge devices arranged on the front left and right sides of an outer frame having an outer opening and an opening / closing front frame adapted to the opening surface area. As shown in FIG. 10, each of the upper and lower hinge devices has a first hinge member 800 in which a shaft support hole 802 is formed in a first plate-like portion 801 arranged horizontally, and a second hinge arranged horizontally. The second hinge member 805 is fixedly provided with a support shaft 807 protruding upward from the plate-like portion 806. In the pair of upper and lower hinge devices having such a configuration, the support shaft 807 is fitted into the shaft support hole 802 to connect the first and second hinge members 800 and 805 horizontally and relatively rotatably, so that the outer frame On the other hand, the front frame is configured to support the swingable opening / closing and detachable.
[0003]
However, in the conventional hinge device as described above, when the front frame is to be attached to the outer frame, the shaft support hole 802 and the support shaft 807 of both the upper and lower hinge devices are aligned together (the shaft There was a problem that it was not easy to work because it had to be engaged (with the hearts aligned). In particular, when mounting in a game facility, the outer frame is fixed to the game island and cannot be moved, and the front frame is incorporated with a game board, a back mechanism board, a control device, etc. For example, since the hinge device is located on the side away from the center of gravity position, there is a problem that it is extremely difficult to perform mounting work for positioning the upper and lower two places.
[0004]
In view of such a problem, for example, as shown in FIG. 11, an introduction opening 803 connected to the shaft support hole 802 from the outer surface is formed in the plate-like portion 801 of the first hinge member 800 ′, and the second hinge member 805 is formed. The left and right sides of the support shaft 807 are cut into a flat shape to form flat portions 807a and 807a, and the width of the left and right flat portions 807a and 807a of the support shaft 807 is slightly narrower than the width of the introduction opening 803. It is known. In this configuration, the support shaft 807 can be inserted into the shaft support hole 802 from the side by passing the left and right plane portions 807a and 807a of the support shaft 807 through the introduction opening 803, and in this state, the first and second If the hinge members 800 ′ and 805 ′ are horizontally rotated relative to each other, the left and right plane portions 807 a and 807 a are rotatably held in the shaft support hole 802. According to this configuration, the support shaft 807 can be moved in the lateral direction and fitted into the shaft support hole 802 without aligning the shaft support hole 802 and the support shaft 807 in the vertical direction. The work of attaching the front frame becomes easy.
[0005]
[Problems to be solved by the invention]
However, in this configuration, when the front frame is rotated to a position where the introduction opening 803 of the shaft support hole 802 and the left and right plane portions 807a and 807a of the support shaft 807 face each other, the support shaft 807 is detached from the shaft support hole 802. There is a problem that the front frame comes off. Although it is conceivable to prevent the above-mentioned problem by providing the position of the introduction opening 803 outside the rotation range of the front frame, the arrangement position of the introduction opening is limited and the introduction opening is assembled when the front frame is assembled. Therefore, there is a problem that it is difficult to assemble the front frame because it is necessary to position the front frame at a position where the left and right plane portions of the support shaft face each other.
[0006]
The present invention has been made in view of the above problems and problems, and can easily attach and detach the front frame and the like to the outer frame and the like with a simple configuration, and once it is attached, the rotation thereof It is an object of the present invention to provide a hinge device for a gaming machine that can be firmly held without being removed from the front frame regardless of the position.
[0007]
[Means for Solving the Problems]
  To achieve the objectives by solving the above problems and issues,BookThe hinge device according to the present invention is disposed above and below the side portion of the gaming machine, and can swing and open an opening / closing member (for example, the front frame 2 in the embodiment) with respect to a base member (for example, the outer frame 1 in the embodiment). A first hinge member (for example, the upper fixing bracket 10 in the embodiment) fixed to either one of the base member and the opening / closing member. The otherParts ofAnd a second hinge member (for example, the upper swing metal fitting 30 in the embodiment) fixed to the head. The first hinge member is fixed to the one member.A first hinge-side plate-like portion that extends horizontally forward, and a spindle that is attached to the first hinge-side plate-like portion so as to protrude upward or downward.The second hinge member is fixed to the other member and protrudes horizontally.And a second hinge side plate-like portion formed with a first shaft support hole having a first introduction portion opened laterally, and a second hinge coaxially and vertically connected to the first shaft support hole and opened laterally. A second shaft support hole having an introduction portion is formed and is configured to include a holding member that is rotatably attached to the second hinge side plate-like portion, and the second position is adjusted by adjusting the rotation position of the holding member. With the introduction portion overlapping the first introduction portion and opened in the same direction, the support shaft passes through the first and second introduction portions and enters the first and second shaft support holes. 2 Rotating the holding member to a position where the introduction portion is disengaged from the first introduction portion holds the support shaft in a state of entering the first and second shaft support holes, and hinges the first and second hinge members. Configured to connect.
[0008]
  According to the hinge device according to the present invention configured as described above, when the opening / closing member (front frame) is connected to the base member (outer frame), the shaft support holes and the support shafts at the two upper and lower positions are connected. There is no need for a delicate adjustment operation such as aligning (centering) and engaging at the same time. For at least one hinge device, the second hinge member is moved closer to the first hinge member from the side and the first hinge member ofSpindleAfter being introduced into the shaft support hole through the introduction portion of the second hinge member,SpindleThe first and second hinge members can be easily hinged by simply holding the shaft in the shaft support hole. In this hinged state,SpindleIs held by the holding member so as not to come out of the shaft support hole, the hinge coupling is firmly maintained regardless of the open / close position of the open / close member. For this reason, the arrangement | positioning position of the introduction opening to a plate-shaped part is not restrict | limited, An introduction opening can be formed in the position which is easy to assemble a front frame, and the assembly operation of a front frame can be made easy.
[0009]
In addition, since the introduction part is open to the side of the shaft support hole, the force acting on the hinge connecting part horizontally forward by the weight of the opening / closing member causes the inner surface of the shaft support hole and the shaft-like body to be separated from the introduction part. It is received by contact. That is, the force acting on the hinge connecting portion in the horizontal front direction due to the weight of the opening / closing member can be received by the plate-like portion, and sufficient strength can be secured. On the other hand, since the holding member does not need to receive the force acting in the horizontal front, high strength is not required, and the holding member can be made of resin or the like to reduce the cost.
[0010]
  According to the present inventionIn the hinge deviceFurtherThe support shaft is composed of a cylindrical portion whose base end portion is fixed to the first hinge side plate-like portion and protrudes upward or downward, and is opposed to the cylindrical portion.ParallelA pair of left and right plane parts consisting of vertical surfaces are formed.On the left and right sidesThe 1st introduction part in the shape which the outer peripheral side was cut off and formed in the 2nd hinge side plate-like part

This hinge device H₁As shown in FIG. 3, the perspective view is shown in FIG. 3. The upper fixing bracket 10 (first hinge member) fixed to the upper left portion of the outer frame 1 and the upper swing bracket fixed to the upper left portion of the front frame 2. 30 (second hinge member), and the upper fixing bracket 10 and the upper swing bracket 30 are hinge-coupled as will be described later. 3 is a perspective view showing a state before the upper fixing metal fitting 10 and the upper swing metal fitting 30 are hinge-coupled. Hereinafter, FIGS. 4 to 9 show the metal fittings and the outer frame 1 using the metal fittings. The hinge coupling operation of the front frame 2 is shown. These figures are shown with the glass door 5 removed in order to clearly show the hinge device.
[0021]
The upper fixing bracket 10 includes a fixed-side base 11 fixed to the upper left corner of the outer frame 1, a fixed-side plate-like part 15 protruding horizontally from the fixed-side base 11 toward the front, and a fixed-side plate-like part 15. And a support shaft 20 protruding upward from the upper surface. The fixed side base 11 has an upper side 12 fixed to an upper mounting surface formed on the upper left portion of the outer frame 1, and a side mounting surface formed on the left outer side of the outer frame 1 orthogonal to the upper side 12. The fixed side plate-shaped portion is composed of a side portion 13 to be fixed and a front side portion 14 that is orthogonal to the upper side portion 12 and the side portion 13 and abuts against the front end surface of the outer frame 1, and is connected to the lower end of the front side portion 14. 15 extends horizontally forward. That is, in the upper fixing bracket 10, after the fixed side base 11 and the fixed side plate-like portion 15 are integrally formed in a shape shown in the drawing by stamping and press forming a steel plate having a predetermined plate thickness, the three sides 12, 13 orthogonal to each other are formed. , 14 is positioned at the upper left corner of the outer frame 1 and fixed to the outer frame 1 with screws 12a, 13a and the like.
[0022]
The fixed-side plate-like portion 15 has the fixed-side base 11 fixed to the outer frame 1 as described above, and the lower hinge device H shown in FIG.₂The support shaft 20 is attached so as to extend coaxially with the axis Ax of the support shaft 115 of the lower fixing bracket 110 and protrude upward. As can be seen from FIG. 8, the support shaft 20 is configured to have a cylindrical portion 22 provided with a flange portion 21 on the lower end side, and the cylindrical portion 22 is inserted into the through hole 16 formed in the fixed-side plate-like portion 15. It is press-fitted from the bottom side. During this press-fitting, the flange portion 21 abuts against the lower surface of the fixed-side plate-like portion 15 for press-fitting positioning, and in this state, the cylindrical portion 22 protrudes upward and downward from the upper surface of the fixed-side plate-like portion 15. Planar portions 23, 23 made of a pair of vertical surfaces are formed. The support shaft 20 is attached to the fixed-side plate-like portion 15 so that the flat portions 23 and 23 are positioned so as to extend in parallel with the vertical front surface of the outer frame 1. Note that a conical chamfer 22 a is provided at the upper end of the cylindrical portion 22.
[0023]
On the other hand, the upper swing metal fitting 30 that is hinged to the upper fixing metal fitting 10 is fixed to the back side of the front frame 2 and the swing side base 31 is bent at a right angle from the swing side base 31 and horizontally forward. And a holding member 40 that is rotatably attached to the swing side plate-like portion 32. The swing side base 31 and the swing side plate-like portion 32 are formed by punching and bending a steel plate having a predetermined thickness into the shape shown in the figure, and then using fastening means such as a screw 38 on the left upper surface of the front frame 2. Fixed. The swing base 31 is provided with a pair of attachment positioning protrusions 31a. When the front frame 2 is closed to the outer frame 1, an attachment positioning recess (not shown) formed in the outer frame 1 is provided. The protrusion 31a is inserted into the inside and is positioned and held.
[0024]
In this upper swing metal fitting 30, the state in which the holding member 40 is removed from the swing side plate-like portion 32 is shown in FIG. 4 and FIG. A first shaft support hole 33 having a first introduction portion 34 that is open in the direction is formed. The distance B between the pair of opening wall surfaces 35 and 35 forming the first introduction part 34 is substantially equal to the width A of the pair of flat surfaces 23 and 23 on the support shaft 20 of the upper fixing bracket 10 (the distance B is slightly smaller than the distance A). The support shaft 20 can enter the first shaft support hole 33 so that the flat surfaces 23 and 23 pass through the first introduction portion 34 between the opening wall surfaces 35 and 35. It has become. At this time, in order to assist the introduction of the support shaft 20, a tapered introduction guide surface 35 a is formed on the outer peripheral side of the opening wall surface 35 so as to spread outward. The diameter of the first shaft support hole 33 is set to be slightly larger than the diameter of the cylindrical portion 22 of the support shaft 20 and sufficiently larger than the interval B of the first introduction portion 34. A pair of screw holes 36 are formed in the swinging plate-like portion 32 with the first shaft support hole 33 interposed therebetween.
[0025]
The holding member 40 is made, for example, by molding a hard resin material, and has a disk-like flange portion 41 and a columnar portion whose outer shape protrudes upward from the flange portion 41 is a polygon (in this example, an octagon). The second shaft support hole 46 is formed in the center and penetrates the flange portion 41 and the columnar portion 45 in the vertical direction. The flange portion 41 and the columnar portion are partly cut out in a fan shape that extends to the outer peripheral side to form a second introduction portion 42. The distance C between the inner peripheral ends 43a, 43a of the pair of left and right opening wall surfaces 43, 43 forming the second introduction portion 42 is slightly narrower than the width A of the pair of flat surfaces 23, 23 on the spindle 20 of the upper fixing bracket 10. The holding member 40 is elastically deformed so as to spread the second introduction portion 42 when the planes 23 and 23 pass through the second introduction portion 42 and the support shaft 20 enters the second shaft support hole 46. It is supposed to let you. For this reason, a force for pushing the support shaft 20 into the second shaft support hole 46 is required. However, when the support shaft 20 enters the second shaft support hole 46, the elastic deformation of the holding member 40 returns to the original state. The support shaft 20 can be temporarily supported in the second shaft support hole 46.
[0026]
A pair of circumferentially extending elongated holes 44, 44 are formed in the flange portion 41 so as to penetrate vertically, with the columnar portion 45 interposed therebetween. The holding member 40 is attached to the swinging plate-like portion 32 as shown in FIG. 3 by screwing an attachment screw 49 through the long hole 44 into the screw hole 36. In addition, when attached in this way, the fastening force of the attachment screw 49 is set to a predetermined value, and the holding member 40 can be rotated in this state. The amount of rotation of the holding member 40 at this time is determined by the circumferential length of the long hole 44 through which the attachment screw 49 passes. Since the outer peripheral surface of the columnar portion 45 of the holding member 40 is formed in an octagon shape, the holding member 40 can be easily rotated using a tool such as a spanner.
[0027]
In addition, the upper and lower hinge device H configured in this way₁, H₂The distance between the upper surface of the fixed side plate-like portion 112 in the lower fixing bracket 110 and the upper surface of the fixed side plate-like portion 15 in the upper fixing bracket 10 (the interval between the upper and lower support surfaces), The distance between the lower surface of 132 and the lower surface of the swing side plate-like portion 32 in the upper swing metal fitting 30 (the distance between the upper and lower supported surfaces) is set to be substantially the same.
[0028]
Hinge device H configured as described above₁, H₂The operation when the two are hinge-coupled will be described below. As shown in FIGS. 3, 4, 6 (a) and the like, the upper and lower hinge devices H are separated from the outer frame 1 and the front frame 2.₁, H₂First, the operator first connects the lower hinge device H₂Paying attention to the above, the lower fixing fitting 110 on the outer frame side and the lower swing fitting 130 on the front frame side are connected. That is, the shaft hole 135 is positioned on the support shaft 115 of the lower fixing bracket, the front frame 2 is moved downward from above, the support shaft 115 and the shaft hole 135 are fitted and connected, and the supported surface portion 132 is fixed by the support surface portion 112. Support. As a result, the weight of the front frame 2 is supported by the lower fixture 10, and the front frame 2 can be easily tilted within a conical angle range centered on the fitting connection point.
[0029]
The operator then moves the upper hinge device H₁Focusing on the above, the connecting operation between the upper fixing bracket 10 on the outer frame side and the upper swing bracket 30 on the front frame side is performed. Connecting operation is the lower hinge device H₂The front frame 2 supported by is tilted and the upper swing metal fitting 30 is moved closer to the right side of the upper fixing metal 10 (see arrow P in FIG. 6A). However, at this time, in the upper swing metal fitting 30, the rotation position of the holding member 40 is set so that the first introduction portion 34 of the swing side plate-like portion 32 and the second introduction portion 42 of the holding member 40 communicate vertically. (The state shown in FIGS. 6A and 8A). Then, the front frame 2 is tilted so that the support shaft 20 passes through the first and second introduction portions 34 and 42 and enters the first and second shaft support holes 33 and 46 connected vertically.
[0030]
As a result, the flat surfaces 23 and 23 of the support shaft 20 pass between the first and second introduction portions 34 and 42, and the support shaft 20 enters the first and second shaft support holes 33 and 46. At this time, as described above, the support shaft 20 can penetrate the first introduction portion 34 without any resistance, but when the support shaft 20 enters the second shaft support hole 46 through the second introduction portion 42. Since the holding member 40 is elastically deformed so as to spread the second introduction part 42, it is necessary to push the support shaft 20 into the second shaft support hole 46 by applying a predetermined pushing force. In this way, when the support shaft 20 enters the first and second shaft support holes 33 and 46, the elastic deformation of the holding member 40 returns to the original and the support shaft 20 supports the first and second shafts. Temporarily supported in the holes 33 and 46. For this reason, the wobbling (free tilting) of the front frame 2 is suppressed in this state, and the front frame 2 is coupled and held to the outer frame 1 in a stable state. This state is shown in FIG. 7 and FIG. However, in this state, when the upper part of the front frame 2 is pushed leftward, the support shaft 20 spreads the second introduction part 42 of the holding member 40 and comes out of the first and second shaft support holes 33 and 46.
[0031]
Therefore, the operator rotates the holding member 40 to the position shown in FIGS. 6B and 8B by engaging a spanner or the like with the outer surface of the columnar portion 45 of the holding member 40. By rotating the holding member 40 in this manner, the position of the second introduction portion 42 is shifted with respect to the first introduction portion 34, and as a result, the support shaft 20 is moved to the first and second shafts by the second introduction portion 42. This prevents the support holes 33 and 46 from coming out. This allows the front frame 2 to move up and down the hinge device H.₁, H₂As a result, the hinge coupling operation can be performed very easily.
[0032]
On the other hand, the removal of the front frame 2 is achieved by a simple operation of pulling it up as it is with the front frame 2 opened at a predetermined angle with respect to the outer frame 1. That is, by lifting the front frame 2 upward, the upper hinge device H₁The swing-side plate-like portion 32 (first and second shaft support holes 33, 46) is moved upward to disengage from the upper side of the support shaft 20, and at the same time the lower hinge device H₂The shaft hole portion 135 is moved upward so that the engagement between the shaft rear portion 135 and the support shaft 115 is released.₁, H₂Since both the hinge connections are released, the front frame 2 can be removed as it is.
[0033]
Thus, the hinge device H₁, H₂According to the above, when attaching the front frame 2 to the outer frame 1, it is not necessary to position the support shaft and the shaft support hole (engagement hole) in the upper and lower hinge devices at the same time. Therefore, the front frame 2, which is a heavy object, can be easily hinged to the outer frame 1. On the other hand, at the time of removal work, the hinge connection to the outer frame 1 can be released by a simple operation of simply pulling the front frame 2 upward.
[0034]
When the front frame 2 is opened and supported with respect to the outer frame 1, the open end side (the anti-connection side, that is, the locking device 4 side) of the front frame 2 is placed on the upper hinge device by the weight of the front frame 2. A moment that pushes down acts, and this moment acts as a force that pulls the upper fixing bracket 10 in the opening direction of the front frame 2, that is, in the front. Hinge device H of the present invention₁In this case, such a force is received by the support shaft 20 coming into contact with the rear inner surface of the first shaft support hole 33 (the portion to which hatching D in FIG. 4 is applied), and the high-strength swing-side plate-like portion 32. It supports both the high long-term reliability and operability. In addition, since it receives the said force by the rocking | swiveling side plate-shaped part 32 in this way, it is not necessary to receive the said force by the holding member 40, and it can aim at the cost reduction by making the holding member 40 with resin etc. .
[0035]
With the front frame 2 hingedly attached to the outer frame 1 as described above, the state in which the front frame 3 is released approximately 90 degrees and the state in which the front frame 3 is completely closed are shown in FIGS. This is shown in b). In this figure, the upper hinge device H on the upper side of the arrow Q is based on the moment generated by the weight of the front frame 2.₁It shows the force acting on. As can be seen from these drawings, any of the forces Q is received on the hatched portion D side of the shaft support hole 33 of the swing side plate-like portion 32.
[0036]
In the above embodiment, the hinge device H is provided at the upper left part of the pachinko machine.₁With hinge device H in the lower left₂However, these hinge devices may be configured upside down. In addition, the hinge device H₁There may be a configuration in which Further, the mounting position of the fixing bracket and the swing bracket may be an arrangement in which the outer frame and the front frame are reversed.
[0037]
In the above embodiment, a pachinko machine has been taken as an example of a gaming machine and described as being applied between the outer frame 1 and the front frame 2, but the present invention is not limited to such a gaming machine or an arrangement site. Absent. For example, in a pachinko machine, it can be similarly applied to a glass door and a back mechanism panel (back set panel) that can be swingably opened and closed with respect to the front frame. The present invention can be similarly applied to a front mask or a medal tray that can be freely opened / closed and attached / detached.

In addition, since the introduction portion is opened to the side of the shaft support hole, the force acting horizontally on the hinge connection portion due to the weight of the opening / closing member is applied to the shaft support hole inner surface and the shaft-like body that are outside the introduction portion. A force acting on the contact portion and acting on the hinge connection portion in the horizontal front direction can be received by a high-strength plate-shaped portion made of a steel plate or the like, and sufficient strength can be secured. On the other hand, since the holding member does not need to receive the force acting in the horizontal front, high strength is not required, and the holding member can be made of resin or the like to reduce the cost.
[0040]
The hinge device according to the second aspect of the present invention also includes a first hinge member having a shaft-like body that is fixed to one of the base member and the opening / closing member and protrudes in the vertical direction, and is fixed to the other and protrudes horizontally. A first shaft support hole having a first introduction portion that opens to the side, and is coaxially connected to the first shaft support hole and vertically communicated therewith. Since the holding member in which the hole and the second introduction portion that opens to the side are formed is rotatably attached to the plate-like portion, the opening / closing member (front frame) with respect to the base member (outer frame) When connecting the first and second shafts, the second hinge member is brought close to the first hinge member from the side, and the shaft is passed through the first and second introduction parts in a state where they communicate with each other vertically. Then, the holding member is rotated to move the position of the second introduction portion. A simple operation referred, the first and second hinge members can be hinged. For this reason, it is not necessary to perform a delicate adjustment operation such that the shaft support holes and the support shafts at the upper and lower two positions are simultaneously aligned (centered) and engaged as in the conventional case, and the hinge connection is performed in this way. In this state, the shaft-like body is held by the holding member so as not to be detached from the shaft support hole. it can.
[0041]
Also in this case, since the first introduction portion formed in the plate-like portion opens to the side of the first shaft support hole, the force acting on the hinge connection portion in the horizontal front direction due to the weight of the opening / closing member is introduced. It acts on the contact part between the shaft support hole inner surface and the shaft-like body, and the force acting on the hinge connection part in the horizontal front can be received by a high-strength plate-like part made of steel plate, etc. High strength can be secured. Further, as in the first invention, since the holding member does not need to receive the force acting in the horizontal front, the holding member can be made of resin or the like to reduce the cost.
