BACKGROUND OF THE INVENTION
The present invention relates to a front frame that can be opened and closed in front of an outer frame, and a front frame that can be opened and closed on an outer frame member such as a glass frame that can be opened and closed in front of the front frame. The present invention relates to a locking device that restricts opening of a member.
[0002]
[Prior art]
Conventionally, in a gaming machine such as a pachinko machine, a front frame is attached to an outer frame so that the front frame can be opened and closed, and the opening of the front frame is restricted by a locking device. Moreover, the glass frame is attached to the front frame so that opening and closing is possible, and the opening of the glass frame is regulated by a locking device. FIG. 15 shows a conventional typical locking device that locks the front frame M to the outer frame S. The conventional locking device is an upper portion of the vertically long base plate 1 provided along the vertical frame on the open side of the front frame M. And an engaging hook 2 that can be tilted at the bottom. In addition, the base plate 1 is provided with a slide member 3 that can be moved up and down along this, and the upper and lower ends thereof are respectively connected to the engagement hooks 2. Can be operated in a locking position in a substantially horizontal position and an unlocking position tilting downward. The slide member 3 is urged downward by a spring member 33, and normally holds both engaging hooks 2 in the locked position. The slide member 3 is slid upward by a key operation of a cylinder lock 10 provided in the middle of the base plate 1 so as to switch both the engagement hooks 2 to the unlocked position. When the front frame M is closed, the locking device locks the front frame by engaging each engagement hook 2 with each engagement metal fitting 4 provided on the vertical frame on the open side of the outer frame S at the above-mentioned locking position ( For example, see Patent Document 1.) Although the illustrated example shows that the engaging hook 2 is unlocked by tilting downward, in the conventional locking device, the engaging hook is tilted upward by lowering the slide member and unlocked. Some will do.
[0003]
In addition, conventionally, when locking the glass frame to the front frame, the locking device is provided in the vertical frame on the open side of the front frame, the engagement metal fitting is provided in the vertical frame on the open side of the glass frame, and when the glass frame is closed, Locking is performed by engaging an engagement hook of a locking device provided on the front frame side with the engagement fitting of the glass frame.
