Description

[Detailed description of the invention] This invention relates to a front frame for assembling a game board in a pachinko machine.The purpose of this invention is to make the front frame of a pachinko machine easier to attach and detach the game board, and to increase rigidity and durability. The goal is to provide the following.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, 1 is a front frame body, which is molded from a synthetic resin material into an almost picture frame shape with an opening 2, and its lower part On the front side, a mounting part 1a for attaching a prize ball tray, a batting ball handle, etc. is formed, while on the back side there are ribs 3 to 3 for reinforcing each frame piece, and ribs 3 to 3 for weight reduction. Cavity parts 4 to 4 are respectively formed.

Note that a heat-resistant decorative layer such as melamine resin or metal foil is attached to the surface side of the front frame main body 1 as necessary, and is attached, for example, in grooves formed in a slightly concave shape with respect to the surface of the front frame main body. .

Reference numeral 5 denotes a locking member formed into a rectangular frame shape made of a metal material and coupled to the back side of the front frame body 1 along the four peripheries of the opening 2 of the front frame body 1 in order to fit the game board U therein. The frame is formed into a substantially Z-shaped cross section, and the front edge 5a of this locking frame 5 is bent outward over the entire circumference, and the vicinity of this front edge 5a is exposed when the front frame body 1 is molded. While being buried integrally within the frame body 1,
The rear end edge 5b of the locking frame 5 is bent inward to prevent the game board U fitted into the locking frame 5 from coming off from behind. A retaining edge 5b is formed over the entire circumference. A through hole 6 is provided near the center of the left and right vertical frame portions 5A, 5A of the locking frame 5.
6 are opened, and a front plate 5C is attached to the lower frame portion 5B of the locking frame 5, and this front plate 5C
A pair of left and right protrusions 7, 7 are provided on the upper edge to protrude upward in order to lock the lower edge of the game board U.

Reference numerals 8 and 8 denote a pair of left and right lock plates respectively attached to the inner surfaces of both vertical frame portions 5A of the locking frame 5;
Vertical guide holes 8a, 8 opened at the top and bottom of the
It is vertically movably attached to the vertical frame part 5A through guide pins 9 to 9 which are fixed to the vertical frame part 5A through the a, and a knob 8b is located in the center of the vertical frame part 5A.
The engagement portions 8c, 8c are recessed in a substantially hook shape at the front end near the upper and lower ends thereof, respectively. , is always urged downward by a spring 11 suspended between the knob 8b and the fixing pin 10.

Reference numerals 12 and 12 denote swinging pieces that are swingably attached to pins 13 on the outer surfaces of both vertical frame portions 8A of the locking frame 5, facing the knobs 8b of the locking plate 8, and are normally attached to the springs 14. A locking portion 12a is formed at the lower end of the lock plate 8 to hold the knob 8b in the upward movement position to hold the lock plate 8 in the upward movement position. .

Reference numeral 15 denotes locking protrusions that protrude from the top and bottom of both sides of the game board U, facing the engaging portions 8c of the lock plate 8, and are designed to lock the game board U from the front side of the front frame body 1 through the opening. 2 into the locking frame 5 and pushed backward, the locking plate 8 is moved upward by contacting the front edge of the engaging portion 8c of the locking plate 8, and each locking protrusion 1
5 is engaged in each engaging portion 8c of both lock plates 8 (see FIGS. 4 and 5), and the lock plate 8 is urged downward by a spring 11 to maintain the above-mentioned engaged state. The game board U is locked in the locking frame 5 via both lock plates 8 and each locking protrusion 15, while when both lock plates 8 are moved upward, the lock plate 8 is locked.
The engagement between the engaging portions 8c and the locking protrusions 15 of the game board U is disengaged, and the game board U is unlocked so that it can be drawn forward from within the locking frame 5.

Note that 16 is a glass frame hinged to the front frame main body 1 in order to open and close the opening 2.

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

In this example, the front frame main body 1 is made of synthetic resin and is molded into a frame shape, and a front edge 5a is formed into a rectangular frame with a metal plate material in order to removably fit the game board U into the front frame body 1. Front edge 5a of locking frame 5 bent outward
In addition to integrally burying the surrounding area, a locking edge 5b bent inward is formed around the entire circumference at the rear end of the locking frame 5 to prevent the game board U from slipping out from behind. Further, the locking frame 5 is provided with a locking means for removably locking the game board U fitted into the locking frame 5.

Therefore, it is possible to simplify the operation of attaching and detaching the game board U to the front frame, and also to simplify the production of the front frame, significantly reducing the number of man-hours and production costs for the front frame compared to the conventional front frame made of plywood. can do.

In addition, since the front frame is formed by integrally embedding the front edge 5a of the locking frame 5 made of a metal material in the front frame body 1 molded from a synthetic resin material, the front frame body 1 is molded from a synthetic resin material. It is possible to strengthen the bonding state with the locking frame, combine the physical properties of the synthetic resin material and the physical properties of the metal plate material, reduce the weight of the entire front frame, and strengthen the front frame body and the locking frame 5 mutually. As a result, the strength characteristics such as rigidity and deformation resistance of the front frame metal body can be ensured despite the weight reduction.

In other words, since the present invention is constructed as described above, it is possible to strengthen the bond between the front frame main body and the locking frame, combine the physical properties of the synthetic resin material and the physical properties of the metal material, and improve the front frame. The overall weight can be reduced, and since the front frame main body and the locking frame mutually reinforce each other, it has the effect of ensuring strength characteristics such as rigidity and deformation resistance of the front frame despite being lightweight. .
