BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable hinge (a type in which a pin is detachably inserted into a bearing hole of a bearing portion) for supporting a door with respect to a main body so that the door can be opened and closed.

[0002]

2. Description of the Related Art Conventionally, for example, as a hinge for opening and closing a door of a slot machine, the hinge comprises a fixed member and a movable member, and a bearing portion is provided at an edge of a mounting plate portion of the fixed member.
There is known a detachable hinge having a structure in which a pin is projected and fixed to a winding portion of a movable member, and the pin is inserted into a bearing hole on the fixed member side to be 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 mount the hinges of the two hinges mounted between the main body and the front door in such a manner that the axes of the rotary shafts are accurately aligned. Therefore, when attaching the two hinges between the main body and the front door as described above, the two fixing members are fixed to the main body side by aligning the shaft center positions of the bearings thereof, and at the corresponding positions on the front door side. It is necessary to fix the two movable members by accurately aligning the axial center positions of the pins, and it is difficult and complicated to attach the hinge, and there is a problem that a lot of time and man-hours are required.

[0004]

SUMMARY OF THE INVENTION Therefore, the inventors of the present invention have disclosed in Japanese Patent Laid-Open No. 10-201922 that a hinge is composed of a vertically long fixed member and a movable member, and that the fixed member has an upper portion in a mounting plate portion. Bearing portions each having a bearing hole are provided in the lower edge portion so that the axial center positions are aligned with one axis, and the winding portions are formed in the upper and lower edge portions of the mounting plate portion of the movable member. A hinge was proposed in which the pins are fixed so that their axial center positions coincide with one axis and project downward, and both pins are inserted into the bearings of the fixing member and assembled.

This hinge is constructed by providing bearing holes, which serve as bearings, on the upper and lower portions of a vertically long fixed member on the same axis, and by mounting pins on the upper and lower portions of the same vertically movable member on the same axis. Therefore, when the fixed member is fixed to the main body of the slot machine and the movable member is fixed to the front door, the front door is attached to the main body, that is, when assembling the hinge, lift the front door and separate it vertically. Work is performed so that another pair of pins are simultaneously fitted into the respective bearing holes.

Therefore, with the heavy front door, the upper and lower pins of the movable member are inserted into the upper and lower bearing holes of the fixed member on the main body side at the same time. The work of positioning and assembling with the bearing hole is
There was a problem that it was difficult and time-consuming. Also, since the pin of the movable member is inserted into the bearing hole of the bearing portion of the fixed member to complete the assembly of the hinge, that is, the front door, the movable member of the hinge can be easily removed from the fixed member by lifting the open front door. There was a problem of coming off.

The present invention has been made in view of the above points, and in a detachable hinge in which a pin and a bearing portion located on the upper and lower sides of a fixed side and a movable side are fitted and assembled, It is an object of the present invention to provide a hinge that can be easily fitted and that does not easily come off once assembled.

The hinge of the present invention for achieving the above object is a detachable hinge which is attached between an openable door and a main body and comprises a vertically elongated first member and a second member. A bearing member with a guide having a bearing portion is fixed to the upper and lower portions of the frame body with the axial center positions of the bearing holes aligned on one axis, and the upper and lower edge portions of the mounting plate portion of the second member. The shaft holding portions, each of which has a pin inserted into and fixed to the winding portion, are provided such that the axial center positions thereof coincide with one axis line, and the guide bearing member includes the winding portion of the shaft holding portion. A guide part for guiding the position is provided with an inclined guide surface, and the pin of the bearing member of the bearing member is fitted below or above the bearing member with the guide in the base frame body of the first member. Prevents movement of the pin or bearing member in the attachment / detachment direction by touching the end Prevention member, characterized in that provided that.

Here, the detachment preventing member is formed of a plate material having spring elasticity, and when the pin is inserted into the bearing portion, the detachment preventing member is elastically deformed and inserted, and after the insertion, the detachment preventing member is returned to the stop position. The pin can be configured to be prevented from moving in the attaching / detaching direction. Further, the disengagement prevention member can be configured by providing a fixing means that is pivotally supported between a stop position and a stop release position in the base frame body of the first member and is fixed at the stop position.

[0010]

In the hinge thus constructed, the first member is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, or vice versa. It is fixed as a member, and the first member is fixed to the main body as a fixed member for use. Further, for example, when the first member of the hinge is fixed to the door as the movable member and the second member is fixed to the main body as the fixed member, the pin provided on the winding portion of the second member is fixed upward. On the contrary, when the second member of the hinge is fixed to the door as the movable member and the first member is fixed to the main body as the 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 hole of the guide-side bearing member on the movable side is held by holding the door. When trying to align with the pin of the shaft holding part of, the inclined guide surface of the guide part provided on the bearing member with guide
The bearing member is guided so as to be aligned with the axial position of the winding portion of the shaft holding portion, and the axis line of the bearing hole and the axis line of the pin are aligned. In this state, if the position of the movable side bearing member is lowered a little, the pin of the fixed side shaft holding portion fits into the bearing hole of the movable side guided bearing member, and the hinge is assembled.

At this time, when the disengagement prevention member provided on the lower side of the bearing portion in the base frame body of the first member on the door side is formed of a plate material having spring elasticity, when the pin is inserted into the bearing portion, the disengagement prevention member is detached. The pin is inserted into the bearing hole by elastically deforming the prevention member,
After the insertion, the disengagement prevention member returns to the stop position, and the movement of the pin or the bearing portion in the attachment / detachment direction is prevented. For this reason,
Even if you try to remove the first member of the hinge from the second member by lifting the door with the door open, the disengagement prevention member prevents the bearing part or the pin from moving in the attachment / detachment direction. It is possible to prevent accidental detachment of the member.
