Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front frame support structure for a gaming machine in which a front frame can be easily pivoted with respect to an outer frame of a gaming machine such as a pachinko machine or a slot machine. .

[0002]

2. Description of the Related Art In a gaming machine such as a pachinko machine and a slot machine, a front frame is rotatably supported by an outer frame so as to be opened and closed with respect to an outer frame for inspection and repair of various gaming machines. The front frame is detachably supported by the outer frame as needed.

In such a gaming machine, various pivotal supports have been used so far so that the front frame can be easily assembled to the outer frame at the time of assembling and manufacturing in a factory or when being installed on the mount of a game hall. A structure has been proposed.

As an example, for example, Japanese Patent Laid-Open No. 9-4755.
As disclosed in Japanese Patent Publication No. 5, a spindle is erected on the upper surface of the hinged portion above the front frame, and a bearing portion is provided in the hinged portion above the outer frame to open a shaft engaging port in the left and right directions. It is known that the front frame is pivotally supported so as to be openable and closable by inserting the support shaft into the bearing portion through the shaft engaging port while horizontally moving.

[0005]

The above-mentioned conventional front frame support structure is a general support structure in which upper and lower support shafts are simultaneously fitted to the bearing portion while supporting the weight of the front frame. Compared with the ones, it is possible to avoid the assembling work while supporting the weight of the front frame, which is advantageous in terms of physical strength and safety, but it is necessary to insert the support shaft into the bearing and the bearing. Since the shaft engaging port is fixedly provided on the outer frame side, the attachment and removal directions of the front frame with respect to the outer frame are inevitably constrained, and during assembly at the factory or installation at the amusement park. There was a problem that the workability of was poor.

The present invention has been made in view of the above problems, and an object of the present invention is to solve the problems of a general shaft support structure, and to dispose the front frame with respect to the outer frame. An object of the present invention is to provide a front frame support structure for a gaming machine, which can be easily and safely attached or removed from any direction to enhance workability.

[0007]

In order to achieve the above-mentioned object, the present invention has a fixing metal fitting fixed to the upper and lower sides of one side of an outer frame, and a horizontal horizontal movable metal fitting fixed to one side of the front frame. In a gaming machine in which a front frame is rotatably supported by opening and closing a front frame by connecting plate portions through a protruding shaft of a fixing bracket, one end is opened in a horizontal plate portion of the movable bracket, and A bearing hole serving as an insertion portion is formed, a lock plate for opening and closing the bearing hole is slidably provided, and the protruding shaft is rotatably supported in the bearing hole by sliding of the lock plate. Is.

In order to firmly maintain the axially supported state of the protruding shaft, it is preferable that the lock plate is provided with a notch groove for axially supporting the protruding shaft so as to be engageable and disengageable.

Further, it is preferable that the lock plate is always biased by a biasing member to a position that closes the bearing hole so that the protruding shaft can be pivotally supported in the bearing hole with one touch.

Further, in order to allow the lock plate to slide smoothly, it is preferable that a flange portion projecting upward is provided at a side edge of the horizontal plate portion of the movable fitting to form a storage space for the lock plate. A wide cutout opening may be provided in the portion so that the protruding shaft of the fixed fitting easily enters the bearing hole of the movable fitting.

Further, in order to facilitate the engagement between the bearing hole and the protruding shaft, it is preferable that the portion of the lock plate where the protruding shaft abuts is formed as a guide portion which is inclined toward the bearing hole.

With this structure, the protruding shaft of the fixing member of the outer frame is inserted into the bearing hole of the movable member of the front frame, and the protruding shaft abuts on the lock plate to slide the lock plate. However, by engaging the protruding shaft and the bearing hole, the front frame can be easily attached to the outer frame.
