Description

[Detailed description of the invention] This invention relates to a tamper prevention device for the glass frame of a pachinko machine.The purpose of this invention is to cover the upper edge of the glass inserted into the glass frame of the pachinko machine and the front surface of this upper edge. To provide a fraud prevention device for a glass frame which can prevent fraud such as intentionally widening the gap between the glass frame and the upper part of the glass frame to insert a wire or the like.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a window frame formed in the shape of a picture frame, which is attached to the front surface of the front frame of a pachinko machine (not shown).

A glass frame 2 is hinged to the window frame 1 so that it can be opened and closed forward, and is formed of a thin metal plate into a rectangular frame shape with left and right vertical frames and upper and lower horizontal bars. On the back side of the lower horizontal frame, a glass support frame part 3 with a corrugated cross section and two grooves 3a to 3a is protruded from the front in a shape. While reinforced by the support frame part 3,
The upper horizontal frame 2a has a glass insertion hole 4 for inserting glass.
is open and the glass support frame is missing.

Reference numeral 5 is a double-glazed glass mounted on the glass frame 2, which is fitted into the groove 3a of the glass support frame 3 through the glass insertion opening 4 and supported by the frame 3.

Reference numeral 6 denotes a locking piece attached to the inner surface near the center of the upper horizontal frame 2a facing near the upper end of the glass 5. The flat surface is formed into a substantially n-shape, and the locking piece 6 and the upper horizontal A pair of engagement holes 7 are formed between the inner surface of the frame 2a and the inner surface of the frame 2a.

Reference numeral 8 denotes a clamping piece that spans between the locking piece 6 and the inner surface 5a near the upper end of the glass 5 in order to restrict forward deformation of the upper horizontal frame 2a. piece 6 and glass 5
The front leg piece 8a is fitted into the engagement hole 7, while the front leg piece 8a is fitted into the engagement hole 7.
The rear leg piece 8b is brought into contact with the inner side surface 5a near the upper end of the glass 5, and the upper horizontal frame 2a of the glass frame 2 is hooked to the upper edge of the glass 5 via the clamping piece 8.

Reference numeral 9 denotes a clamping fitting that is straddled between the upper ends of both the glass support frame parts 3 of the left and right vertical frames, and is a gap between the left and right leg pieces 9a that are hung on the glass support frame part 3 and the upper end of the glass 5. The horizontal piece 9b is fitted into the gap 10, and the horizontal piece 9b is formed into a substantially rectangular shape. Compressive deformation of the upper ends of both glasses 5 is restricted.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, a locking piece 6 is installed on the inner surface of the upper horizontal frame 2a of the glass frame 2 in order to form a set of engagement holes 7 facing near the upper end of the glass 5 fitted into the glass frame 2. At the same time, a clamping piece 8 is straddled between the engagement hole 7 and the inner surface 5a near the upper end of the glass 5 in order to restrict forward deformation of the upper horizontal frame 2a. Upper horizontal frame 2a and glass 5
Even if you intentionally try to widen the gap with the upper end, the clamping piece 6
As a result, the forward bending of the upper horizontal frame 2a, which is fixed to the upper end of the glass 5 via the upper horizontal frame 2a, is reliably suppressed, and as a result, the deformation of the upper horizontal frame 2a is effectively restricted by effectively utilizing the rigidity of the glass 5. This has the effect of preventing fraudulent acts carried out by inserting a wire, screwdriver, key, cannula, etc. into the gap.

In particular, in this example, since the clamping fitting 9 is press-fitted into the gap 10 at the upper end of the glass 5, the force that widens the gap between the upper horizontal frame 2a and the upper end of the glass 5 is exerted by the two glasses 5. accepted,
This has the effect of reliably suppressing deformation of the upper horizontal frame 2a by the deformation resistance of the two glasses 5.

That is, in the present invention, a locking piece is attached to the inner surface of the upper horizontal frame of the glass frame of a pachinko machine to form a set of engaging holes facing the vicinity of the upper end of the glass fitted into the glass frame. In addition, a clamping piece is straddled between the engagement hole and the inner surface near the upper end of the glass in order to restrict forward deformation of the upper horizontal frame, so that the upper horizontal frame and This invention is extremely practical as a device for preventing fraud on the glass frame of a pachinko machine, since it is possible to prevent unauthorized acts against the glass frame by restricting the expansion of the gap between the glass frame and the upper end of the glass.

In the above embodiment, a plurality of clamping pieces 6 may be applied to the glass frame 2.

Moreover, the clamping piece 6 may be formed of a wire material or a strip material instead of a plate material.
