Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a structure that prevents deformation of the front metal frame of a pachinko machine when a glass door frame holding a glass plate is attached.

[Conventional technology]

Conventionally, a glass door frame has been pivoted to the outer frame so that it can be opened and closed by supporting pins P arranged at the upper and lower ends of one side of the frame on one side of the outer frame (see FIG. 5). This outer frame was then fixed to the wooden frame K with screws to form the front plate of the pachinko machine.

[Problem that the idea aims to solve]

However, the pivoting side between the glass door frame and the outer frame is weak because only the top and bottom pins are connected, so it is easy to insert a screwdriver D etc. through the gap on the pivoting side and pull the glass door frame toward you, as shown in Figure 5. There have been instances where I have been harassed and engaged in misconduct.

[Means to solve the problem]

Therefore, the present invention attempts to secure the immobility of the glass door frame by locking it to the outer frame, thereby preventing unauthorized acts, and reinforcing the outer frame. For this reason, the present invention provides a front metal frame that includes an outer frame and a glass door frame in which security grooves are connected, and in which the glass door frame is rotatably pivoted on one side of the outer frame that is attached and fixed to the wooden frame. A glass door frame with an outward-facing locking piece fixed to the glass holding plate on the pivoting side, and an outer frame with a rearwardly protruding stopper piece fixed to the back of the security groove on the pivoting side of the glass door frame. The structure is such that the locking piece of the glass door frame is brought into contact with the back surface of the stopper piece for closing and mounting.

[Effect]

When the glass door frame is closed, the locking pieces protruding from the back of the pivoting side of the glass door frame rotate together and come into contact with the back of the stopper piece joined to the wooden frame, making it impossible for unauthorized persons to do so. The glass door frame will not be pulled toward you even if it is pulled from the front.

【Example】

Hereinafter, details of the present invention will be explained with reference to illustrated embodiments. In this example shown in FIGS. 1 to 3, reference numeral 1 denotes an outer frame, on the inside of which a security groove 1a is continuously provided. In addition, stopper pieces 1b are welded to the upper and lower parts of the back of the security groove 1a, and the engagement groove formed by bending the stopper piece 1b on the shaft mounting side is connected to the protruding step Ka.
At the same time, the outer frame 1 is fixed to the wooden frame K with screws. Note that the stepped portion Ka of the wooden frame K is brought into a protruding state by cutting out the front surface of its inner periphery to form a notched portion Kb. 2 is a glass door frame, and a pair of vertical pins P wound around the pivoting side of the door frame are inserted into the support holes of a washer 1c pivoted to the outer frame 1, and pivoted to the outer frame 1. are doing. A locking piece 3 is provided to protrude outward from a holding plate portion 2b of a glass plate in the glass door frame 2. In other words, the holding plate portion 2b has two glass plates G on the front and back.
A connecting plate part 2e is interposed between the two front and rear holding groove forming plate parts 2c and 2d to hold them at a distance, and a locking piece is provided on the connecting plate part 2e and the rear holding groove forming plate part 2d. 3 are caulked and welded at the top and bottom. Note that 4 is a crosspiece and 5 is a play board. Since this example is configured in this way, the glass door frame 2
When closed, the locking piece 3 rotates forward and comes into contact with the back surface of the stopper piece 1b arranged at the upper and lower parts of the outer frame 1, as shown in FIGS. 1 and 2. Therefore, even if an attempt is made to move the pivoting side of the glass door frame 2 toward you with a screwdriver or the like, the locking piece 3 is locked to the stopper piece 1b, so it will not move, and fraudulent acts can be prevented. In this manner, according to this example, the locking piece 3 fixed to the glass door frame 2 locks on the stopper piece 1b on the fixed side, so that incorrect deformation on the fixed side can be prevented. Furthermore, since the stopper piece 1b is covered with the protruding part Ka, the wooden frame K and the outer frame 1 are reinforced. Although this example is configured as described above, the present invention is not limited to this. For example, the shape, length, number of attachment pieces, attachment location, and fixing means of the locking pieces are not limited. In addition, the part that the locking piece comes into contact with when the glass door frame is closed may be a stopper piece that is fixed to the outer frame, and as shown in FIG. It is also possible to have a configuration in which

[Effect of the idea]

Therefore, according to the present invention, when the glass door frame is closed, the locking piece provided on the glass door frame is locked to the back of the stopper piece fixed to the outer frame, so that the pivoting side of the glass door frame is locked. Since it becomes immobile and solid, it is highly effective in preventing fraudulent activities in this area, and it also has the advantage that the outer frame itself is reinforced by the continuous installation of stopper pieces.
