Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a front window frame with a transparent portion that covers the front surface of a game board.

[Prior Art] As is well known, a pachinko machine has a frame-shaped door frame hinged to the front of the machine frame, and a game board installed inside can be seen through a window in the door frame. In order to prevent pachinko balls from flying out onto the game board, as well as to prevent illegal gaming activities, the window in the door frame is fitted with double glass on the front and back. The game board surface can be seen through the glass.

Usually, the above-mentioned glass is fitted into a metal glass frame (generally referred to as a metal frame), and the glass frame is hinged to the window so that it can be opened and closed freely.

As described above, the front surface of the game board has traditionally been covered with a double layer of glass fitted into a glass frame, and a number of proposals have been made regarding this glass frame in order to prevent fraudulent gaming activities. In particular, it has been a long-standing challenge to prevent fraudulent acts that occur between the glass frame and the glass periphery, to improve the production efficiency of glass frames with security mechanisms, and to obtain glass frames that are easy to handle. It becomes.

Conventional proposals related to this include, for example, Utility Model Application No. 51-67.
No. 090, No. 52-23284, No. 53-1
Inventions of Publication No. 2082, Publication No. 53-12083, etc.
There is.

However, these ideas were mainly aimed at improving the security function of the glass frame, and were not concerned with ease of manufacture or handling.

[Problems to be Solved by the Invention] In view of the current situation, the present invention provides more reliable crime prevention II.
It was developed with the aim of improving manufacturability as well as improving workability during maintenance and inspection. The part corresponding to one sheet of glass to be attached is integrally molded as a front window frame, completely eliminating the gap that conventionally occurred between the two, and solving the poor manufacturability of glass frames made of metal materials.

To provide an improved front window frame for a pachinko machine that improves accuracy and productivity and allows dirt to be easily removed during use.

[Means for Solving the Problems] The present invention has been made for the above-mentioned purpose, and its feature is that at least the center portion of one side edge of the window of the door frame formed in the shape of a picture frame is made transparent. A window frame plate is hinged to open and close freely to close the window, while a transparent plate is hinged to the back side of the window frame plate via a hinge, and this transparent plate is placed behind the transparent body at a distance. This is because we decided to set it up.

The most distinctive feature of this invention is that a transparent part is integrated into the window frame plate, which corresponds to a conventional metal glass frame, and the part corresponding to glass is integrated. The transparent body of the window frame plate and the transparent The purpose is to enable maintenance work such as cleaning the board to be performed easily and quickly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to illustrative embodiments.

[Embodiment] Fig. 1 is a front view showing an embodiment of the present invention, Fig. 2 is an enlarged longitudinal sectional side view taken along the line ■-■ in the above figure, and Fig. 3 is a partially FIG. 3 is a cutaway enlarged plan view.

The code 1 in the figure is the machine frame, and 2 is the hinge 3 on one side edge of this machine frame.
4 is a window frame plate which is housed in a window 5 of this door frame through a hinge 6 so that it can be opened and closed freely.

Reference numeral 7 designates a front plate which is also hinged below the window frame plate to close the lower part of the window 5.

The door frame 2 has a game board 8 housed in its front part, and a mechanism frame 1O formed into the original shape made of a metal plate that carries various mechanical parts behind it, is fixed to the back side of the door frame 2, and the back of the window 5 to be opened is blocked. , At the bottom of the front, there is a handle 11 for operating the ball launcher. The window frame plate 4 to which the prize ball tray 12 is attached is made entirely of a transparent material made of synthetic resin such as acrylic resin, and is sized to cover almost the entire game board 8. . This window frame board 4 is coated opaquely with the peripheral part 13 leaving the central part corresponding to the area surrounded by the game part provided in the center of the front surface of the game board, that is, the area that guides and partially surrounds the launching ball. However, a transparent body 14 is provided in the remaining central portion so that the game board can be seen through.

Reference numeral 15 denotes a transparent plate attached to the back side of the window frame plate 4 via a hinge 1B so as to be freely openable and closable.

The transparent plate 15 shown here has a circular shape corresponding to the circular shape of the transparent body 14, and has a flange 17 extending along its periphery so that the entire transparent plate 15 has a dish shape.

This transparent plate connects the locking piece 1B from the collar 17 on the free end side to the top and bottom.
A rotary hook 18 is hooked to the locking piece to fix the window frame board 4 in a state facing the back surface thereof, and the window frame board 4 is set opposite to the transparent body 14 to form a double transparent board. ing.

As described above, the window frame board 4 having the transparent plate 15 on the back side is integrally provided with security fitting grooves 20 on the upper edge and left and right side edges, and the window frame plate 4 of the door frame 2 is
When the windows 5 are closed together, a protrusion 21 provided along the inner periphery of the window 5 is inserted into the receiver to fill the gap between the two, while a protrusion 22 protruding rearward is provided on the lower edge to close the front plate 7. It is also fitted into the crime prevention fitting groove 23 provided on the upper side so as to fill the gap between the two.

The front plate 7 is equipped with a receiving tray 24 for receiving a prize ball and a ball supply device g1 (not shown) on the back side, and the front plate 7 is first closed against the window 5, as shown in FIG. As shown in the figure, the protrusions 25 provided on both side edges and the lower edge are inserted into the groove 2B provided along the inner circumference of the window 5 to close it, and then the window frame plate 4 is closed to close the entire window 5. Become.

[Effects of the Invention] The present invention is constructed as described in the above embodiment, and a game board is created by directly hinged window frame board 4 integrally having a transparent holiday on door frame 2 provided with window 5. Since the structure is designed to cover the front of the window frame, the structure is simpler compared to the conventional glass frame used to cover the game board, and assembly is easier. Since the transparent body 14 is not integrally formed inside the body 4, it becomes more complete and has the advantage of increasing the crime prevention effect.

In addition, the conventional method of installing glass in a glass frame was to fit the peripheral edge of the glass into a groove provided along the inner periphery of the glass frame from above. When removing dirt, at least one piece of the glass must be removed by sliding it upwards before cleaning such as wiping, which is extremely troublesome. However, in the present invention, the transparent plate 15 If it is opened via the hinge 1B, not only the front side of the transparent plate but also the back side of the transparent body 14 can be easily exposed, which has the advantage that the work can be done easily and quickly.

In addition, the present invention has excellent productivity and is suitable for mass production since the window frame plate 4 is made of synthetic resin and integrally molded in a circular part, and since uniform molding is possible, the metal plate can be bent. The pachinko machine can be manufactured with higher precision than the conventional glass frame manufacturing method, and therefore, when the door frame is closed, there is no gap in the mating part. can be provided.
