Description

  The present invention relates to a hinge of a detachable type (a type in which a pin is detachably inserted into a bearing hole) that supports a door so that the door can be opened and closed.

  Conventionally, for example, as a hinge that supports the door of a slot machine so that it can be opened and closed, it is composed of a fixed member and a movable member. There is known a detachable hinge having a structure that protrudes downward and is fixed, and the pin is inserted into a bearing hole on the fixing member side and assembled. This hinge is usually attached to two places, an upper part and a lower part between the main body and the front door, because the shape of the game machine is large.

In order to smoothly open and close the door of the slot machine, it is necessary to attach the rotary shafts of the two hinges mounted between the main body and the front door so that the axial center positions thereof are accurately aligned. Therefore, when two hinges are attached between the main body and the front door as described above, the two fixing members are fixed to the main body side with the axial center position of the bearing portion aligned, and the corresponding positions on the front door side are fixed. The two movable members have to be fixed with their pin centers accurately aligned, making it difficult and cumbersome to attach the hinges, and requiring a lot of time and man-hours.
Japanese Patent Laid-Open No. 2003-13689

  In view of the above, the present inventors disclosed in Patent Document 1 or the like a hinge comprising a vertically long fixed member and a movable member, each bearing having a bearing hole in the vicinity of the upper end and the lower end of the base frame of the movable member. Are provided with the axial center position aligned on one axis, and each pin has an axial center position on one axis on the winding part formed in the vicinity of the upper and lower ends of the mounting plate portion of the fixing member. A hinge has been proposed that is matched and protrudes upward and is fixed, and a pair of upper and lower bearing portions of the movable member are fitted to each pin of the fixed member and assembled.

  This hinge is provided with pins on the same axis as the vertical axis in the vicinity of the upper and lower ends of the vertically long fixed member, and a bearing portion having a bearing hole in the vicinity of the upper and lower ends of a similar vertically long movable member on the same axis. Since the fixed member is fixed to the main body of the slot machine and the movable member is fixed to the front door, the hinged movable member is positioned with respect to the fixed member so that the front door is attached to the main body. Thus, it can be easily assembled.

  However, the length of the vertical side of the front door of a game machine such as a slot machine is as long as about 80 cm, and the lengths of the fixed member and the movable member of this kind of hinge attached to the vertical side of the front door are similarly formed. For this reason, in the state of use with the hinge assembled, the pin and the bearing portion are rotatably fitted and assembled near the upper and lower ends of the fixed member and the movable member, that is, near the upper and lower ends between the cabinet and the front door. Although the pin shaft support portion between the member and the movable member is firmly connected, in the case of the above game machine, the distance between the upper and lower pins and the pin and the upper and lower bearing portions and the bearing portion is about 70 cm long. The long part including the vicinity of the part is not connected.

  In other words, in a game machine that uses this type of hinge to attach the front door so that it can be opened and closed, the upper and lower ends of the hinge are firmly connected by the fitting of the pin and the bearing portion, but about 70 cm including the upper and lower central portions. In the middle part of the vertical side, the front door is simply superimposed on the cabinet.

  For this reason, if an unauthorized tool such as a screwdriver is inserted into the gap between the fixed member and the movable member formed near the top and bottom of the hinge and is forced to open for the purpose of unauthorized unlocking of the game machine, There is a possibility that a gap between the fixed member and the movable member is pushed open.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a hinge that can prevent an illegal act that pushes and opens the vicinity of the center.

  To achieve the above object, a hinge of the present invention is a detachable hinge that is attached between an openable / closable door and a main body and includes a vertically long first member and a second member. A bearing member having a bearing hole in the bearing portion is fixed to the upper and lower portions of the body so that the axial center position of the bearing hole coincides with one axis, and the upper and lower edges of the mounting plate portion of the second member In addition, in the hinge in which the shaft holding portions each having a pin inserted / fixed in the winding portion are provided with the axial center position aligned on one axis, the middle point in the vertical and vertical directions of the base frame of the first member In the vicinity, a bearing member having a bearing hole in the bearing portion is fixed so that the axial center position of the bearing hole coincides with the one axis line, and the edge near the middle point in the vertical direction of the mounting plate portion of the second member A shaft holding portion in which a pin is inserted and fixed to the winding portion is provided in the portion so that the axial center position coincides with the one axis line, Some member and the second member, one upper arranged on the axis of the three pins of the lower and middle point near the corresponding fitted to the bearings, characterized in that it is assembled. Here, the vicinity of the midpoint is a concept including the midpoint of the longitudinally long first member and the longitudinal direction (vertical direction) of the second member and the vicinity thereof.

  According to this invention, the first member and the second member of the hinge can be assembled by fitting the three pins near the upper, lower and middle points to the bearing portion, so that the front door of the game machine to which the hinge is attached, etc. For the purpose of unauthorized unlocking, inserting an unauthorized tool such as a screwdriver into the gap between the first member and the second member of the middle part including the vicinity of the middle point in the vertical and vertical directions of the hinge, and forcibly pushing it open, The vicinity of the midpoint of the hinge is firmly connected by the fitting of the pin and the bearing portion, and the push-opening of the gap can be prevented, thereby preventing illegal acts.

  Here, the base frame body of the first member is formed in a channel material shape having a substantially U-shaped cross section, and an opening is formed at a fixed position of the upper and lower portions of the base frame body and the bottom wall near the midpoint. And the bearing member which has a bearing hole in a bearing part can be fixed so that it may fit in this opening part.

  According to this invention, the bearing member can be efficiently and accurately fitted to the fixed position of the base frame body by using press caulking or the like.

  According to the present invention, for example, when the bearing hole of the movable-side bearing member is to be aligned with the pin of the fixed-side shaft holding portion, the one side wall of the base frame body is used as the guide portion and the shaft holding portion is wound. For example, the bearing hole of the movable-side bearing portion can be easily fitted into the fixed-side pin and the hinge can be assembled so as to match the axial line position of the pin and the bearing hole while the portion is applied to the side wall. Further, there is no need to provide a special guide portion, and the structure of the bearing member and the like can be simplified.

  Further, a disengagement prevention piece is extended to a part of the bearing member, a screw hole for screwing the disengagement prevention bolt is provided in the disengagement prevention piece, and the bearing hole and the pin of the bearing portion of the bearing member are fitted to each other. With the member and the second member assembled, the detachment prevention bolt can be screwed into the screw hole.

  According to this invention, in the assembled state of the hinge in which the bearing hole of the bearing member of the first member and the pin of the second member are fitted, the detachment prevention bolt is screwed into the screw hole of the detachment prevention piece to prevent the detachment. The tip of the bolt comes into contact with the end of the pin, making it impossible for the pin or the bearing member to move away from each other, and preventing the first and second members of the hinge from being illegally disconnected. .

  The hinge configured in this manner fixes the first member to the door as a movable member and the second member to the main body as a fixed member, or conversely, fixes the second member to the door as a movable member. The first member is fixed to the main body as a fixing member. Further, for example, when the first member of the hinge is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, the pin provided on the winding portion of the second member is fixed upward. Conversely, when the second member of the hinge is fixed to the door as a movable member and the first member is fixed to the main body as a fixed member, the pin provided on the winding portion of the second member is fixed downward.

  For example, when the first member of the hinge is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, the bearing holes of the bearing members near the upper, lower and middle points on the movable side are held with the door. The axis of the three bearing holes and the axis of the three pins are made to coincide with the upper and lower portions of each shaft holding portion on the fixed side and the pins near the midpoint. In this state, the pin of the fixed-side shaft holding portion can be easily fitted into the bearing hole of the movable-side bearing member and the hinge can be assembled by simply lowering the position of the movable-side bearing member.

  According to the hinge of the present invention, the first and second members of the hinge can be assembled by fitting the three pins near the upper, lower and middle points to the corresponding bearings. Even if an unauthorized tool is inserted into the gap between the first member and the second member in the middle part including the middle point of the direction and forced to open it, the middle part of the hinge is firmly connected by the fitting of the pin and the bearing part. It is possible to prevent the cheating by preventing the gaps from being pushed open.
