Description

[Detailed Description of the Invention] (Industrial Application Field and Conventional Problems) The present invention relates to a structure for reinforcing the upper frame side of the middle frame for a glass door in the metal frame of a pachinko machine.

Conventionally, as shown in Figure 5, the outer frame of the metal frame of a pachinko machine and the inner frame for the glass door (hereinafter simply referred to as the inner frame) have been used.
There was a problem in which many people committed fraudulent acts by inserting a coin or screwdriver into the T between the upper frame sides and deforming the upper frame sides of the middle frame.

(Purpose of the invention) Therefore, the present invention provides a structure that can reinforce the upper frame side of the inner frame, and aims to prevent deformation due to fraudulent acts.

(Example) Hereinafter, details of the present invention will be explained with reference to illustrated embodiments.

In the middle frame s of this example shown in FIG. 1, 1 is a front frame sap material exposed at the front, 2 is a partition material disposed at the rear thereof and connected to the glass storage frame K, and the front frame sap material 1 and the partition material 2 form an upper frame side portion.

Note that the lower end of the front frame sap material 1 is folded back and the locking part 1 is
a is provided to protrude upward and the rear end side portion of the partition member 2 is folded back to the front side to form a pipe-shaped engaging portion 2a (see FIG. 3).

Reference numeral 3 denotes a reinforcing member having a projecting piece 3a projecting from one longitudinal end thereof and folding the other end inward to form a pipe-shaped attachment portion 3b. 3c is a finger hole for opening the reinforcing member 3 which has been rotated closed.

Next, the operation of this example will be explained. First, the reinforcing material 3 is provided on the partitioning material 2 by fitting the attachment portion 3b of the reinforcing material 3 onto the engaging portion 2a of the partitioning material 2, as shown in FIG. As a result, the reinforcing piece 3 uses the engaging portion 2a as a fulcrum.
can be rotated back and forth.

In addition, in order to ensure the fitted state, the fitted portion may be caulked or lightly pressed with a finger, thereby preventing the reinforcing piece 3 from coming off.

Next, after inserting the glass plate 4 from above between the front frame sap material 1 and the partition material 2, the reinforcing material 3 is rotated forward. As a result, the reinforcing material 3 becomes the partition material 2.
The projecting piece 3a is inserted in front of the locking part 1a of the front frame sap material 1 (the fourth
(see figure). Then, the second glass plate 5 may be inserted from above after the partition material 2.

According to this example, the reinforcing material 3 has a structure in which the front frame side material 1 and the partition material 2 are connected with the protruding piece 3a being locked to the locking portion 1a, so that the upper frame side portion is reinforced. Even if you try to pry the upper frame side of the middle frame from the front with a screwdriver or the like, it will not easily deform, which can prevent fraudulent activity. That is, in the past, the front frame sap material, which was a single structure, was easily deformed due to fraudulent acts, but in this example, the front frame sap material 1 is connected to the partition material 2 via the reinforcing material 3, so that the front frame sap material is easily deformed due to fraudulent acts. This is because the sap material 1 is difficult to deform. In addition, the attachment part 3 of the reinforcing material 3
b and the engaging portion 2a of the partition material 2 are formed into pipe shapes by folding back their respective materials, so that after engaging the two, simply by lightly pressing the engaging portion, the two can be reliably engaged and removed. There is also the operational effect that the reinforcing material 3 can be attached extremely easily.

In addition, the one equipped with a rotating reinforcing piece (utilized in 1983)
-21590), but since it does not have a wide partition like the one in this example, there is a risk that unauthorized pieces may infiltrate later if left for a short time.

(Structure of the invention) Although this example is structured as described above, the invention is not limited to this.

In short, the present invention forms the upper frame side part of the middle frame for a glass door by the front frame sap material exposed at the front and the partitioning members connected to the upper ends of both sides of the glass storage frame to partition two pieces of glass at the upper end. In this case, a reinforcing member is provided in which a protruding piece is protruded from one side in the longitudinal direction and a folded mounting portion is formed on the other edge, and the reinforcing material is provided at an engaging portion formed folded back on the rear end side of the partition member. The reinforcing member is rotatable in the front and back direction using the engaging part as a fulcrum by engaging the attachment part of the material, and by rotating the reinforcing member in the front direction, the projecting piece is moved to the above-mentioned surface. It is configured to be locked to a locking part formed on the back side of the frame sap material.

(Effects of the invention) Therefore, the invention has the following effects.

(b) The double structure of the partition material and the reinforcing material creates a strong upper frame side, and the reinforcing material connects the front frame sap material and the partition material to reinforce the upper frame sap material of the middle frame. Therefore, it will not be easily deformed even if it is pried open with a screwdriver, etc., and fraudulent acts can be prevented.

(b) Since the front glass plate is locked and housed by the partition material, even if there is a slight delay, unauthorized pieces that enter the system will not be able to move back from the partition material, thereby preventing fraudulent activities. In this regard, with conventional partitions using a horizontal axis, a gap is created between the glass plate and the front glass plate, allowing unauthorized pieces to penetrate further into the interior.

(c) Since the reinforcing material is engaged with the partitioning material, it does not protrude beyond the glass storage frame when in the locked state of use, so it does not interfere with other members or devices and space can be used effectively.

(d) Since the reinforcing material is engaged with the partition material, the number of parts is small and the structure is simple and easy to handle.

(e) Since the reinforcing material is connected to the partitioning material, the reinforcing material can be easily installed in pachinko parlors by using an inner frame in which the engaging portion is formed in advance on the partitioning material. The ability to attach reinforcing materials according to the situation is also very effective.
