Description

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

The present invention relates to a mounting structure for a front metal frame of a pachinko machine, which is composed of a glass door frame and an outer frame that supports the glass door frame.

[Prior Art] Conventionally, a glass door frame was pivoted to the outer frame so that it could be opened and closed by supporting pins P placed at the upper and lower ends of one side of the frame on one side of the outer frame. (See Figure 4). 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 only connected by upper and lower pins, and there is a gap in order to ensure rotation of the glass door frame. Then, as shown in Figure 5, by inserting the piano wire D, etc. between the security groove of the outer frame on the shaft attachment side and the glass door frame, or from the mounting end of the outer frame, the piano wire D, etc. can be easily inserted into the play area. There were cases of cheating in order to reach board E.

[Means to solve the problem]

Therefore, the present invention aims to prevent fraudulent acts by locking the pivoting side of the glass door frame to the outer frame to block the gap, and also to prevent fraudulent acts caused by deformation of the outer frame by reinforcing the outer frame. It is something to do. 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 wooden frame is formed by cutting out the front part of the inner periphery to form a stepped part, and a protruding part is made to protrude from the back part of the inner periphery, and an outward-facing shielding piece is fixed to the glass holding plate part on the shaft attachment side. A reinforcing piece having an engaging groove opened outward by bending is fixed to the back side of the security groove on the pivoting side of the glass door frame, and an outer frame of the glass door frame. It consists of a crosspiece with an escape part for rotating the shielding piece on the inner peripheral front part on the shaft attachment side, and a crime prevention groove is accommodated in the notched part of the wooden frame, and the protruding part is covered with a reinforcing piece. The outer frame is fixed to the wooden frame, and the relief part of the crosspiece fixed to the wooden frame is placed behind the reinforcing piece.
The structure is such that the shielding piece of the glass door frame is brought into contact with the back surface of the reinforcing piece to be closed and attached.

[Effect]

When the glass door frame is closed, the shielding piece protruding from the back of the pivoting side of the glass door frame rotates together and comes into contact with the back of the reinforcing piece fixed to the outer frame at the rear of the wooden frame. Since the gap is closed, further intrusion of piano wires etc. can be prevented. At this time, there is no hindrance to the rotation of the shielding piece since the crosspiece has no relief space.
Furthermore, since the wooden frame is reinforced because the shielding piece covers the protruding part of the wooden frame, the metal frame will not be deformed even if it is illegally 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, reinforcing pieces 1b are welded to the upper and lower parts of the back of the security groove 1a, and the outward engaging groove formed by bending the reinforcing piece 1b on the shaft mounting side engages with the protrusion Ka. At the same time, the outer frame 1 is fixed to the wooden frame K with screws. Incidentally, the protruding part Ka of the wooden frame K becomes a protruding state by providing a notched part Kb for arranging a security groove on the front surface of the inner periphery thereof. 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. Shielding pieces 3 are provided on the holding plate portion 2b of the glass plate in the glass door frame 2 so as to project outward from the upper and lower portions facing the reinforcing pieces 1b. In addition, at the rear of the reinforcing piece 1b, the front end of the inner circumference of the crosspiece 4 interposed between the play board 5 and the wooden frame K is slightly cut out to secure an escape space N for rotating the shielding piece. There is. Since this example is configured in this way, the glass door frame 2
When closed, the shielding piece 3 rotates forward in the relief space N and comes into contact with the back surface of the reinforcing piece 1b arranged at the upper and lower parts of the outer frame 1, as shown in FIGS. 1 and 2. Become. Therefore, even if the piano wire D is inserted between the glass door frame 2 and the outer frame 1 on the pivoting side, the shielding piece 3 is in contact with the reinforcing piece 1b, so the gap is closed, so the piano wire D cannot penetrate further inside. As described above, according to this example, since the shielding piece 3 fixed to the glass door frame 2 comes into contact with the reinforcing piece 1b on the fixed side, it is possible to prevent unauthorized access from the gap on the fixed side. Even if a gap occurs between the shielding piece 3 and the reinforcing piece 1b due to long-term use, the inserted piano wire D will remain in the escape space N and will be less likely to reach the distant play board 5. It is. In addition, since the crosspiece 4 lacks the escape space N, the space in front of the play board 5 can be reduced by arranging the crosspiece 4 closer to the inside, which effectively prevents fraudulent activities. Furthermore, since the reinforcing piece 1b covers the stepped portion Ka, the outer frame 1 itself and the wooden frame K are reinforced and made strong, thereby preventing deformation. Especially the missing part
The fact that the protruding portion Ka, which is thin due to the absence of Kb, is attached provides an excellent structure. Although this example is configured as described above, the present invention is not limited to this. For example, the shape, length, number of attachments, attachment location, and fixing means of the shielding pieces are not limited. Further, the shape of the reinforcing piece is not limited either, but it may be sufficient as long as it can cover the protruding part of the wooden frame.

[Effect of the idea]

Therefore, according to the present invention, when the glass door frame is closed, the shielding piece provided on the glass door frame comes into contact with the back of the reinforcing piece fixed to the outer frame at the back of the door, so that there is no communication with the inside. Since the space between the two sides is closed, it has a great effect in preventing fraudulent activities in this area, and since the escape part allows the crosspiece to be placed closer to the inside, unnecessary spaces can be reduced and crime prevention is good. Furthermore, since the reinforcing piece covers the protruding part of the wooden frame, there is an advantage that the outer frame and the wooden frame are strongly reinforced and will not be deformed.
