The launch handle 35 is attached to the attachment boss portion 36 from the front side of the front frame 3 through the above-described through hole after the attachment plate 39 on which other components are mounted is attached to the front frame 3.
[0015]
In addition, although the launching apparatus 13 of this embodiment shall drive the rocking | fluctuating striker 31 with the drive motor 34, the structure of the launching apparatus 13 is not restricted to this. For example, it is also possible to use a launching device configured to launch a game ball by providing a striking rod that can reciprocate in the axial direction and driving the striking rod in the axial direction with a solenoid or the like.
[0016]
Further, as shown in FIGS. 3 and 5, riding means 60 is formed in the lower portion of the mounting plate 39. The ride-on means 60 has a substantially flat support piece portion 40 fixed to the back side of the front frame 3 with a wood screw or the like, and a cross section “「 ”from the lower edge portion of the support piece portion 40 toward the back side of the front frame 3. A running piece 41 extending in a letter shape, a lower piece 42 extending from the riding piece 41 along the lower surface 3a of the front frame 3 toward the front side, and a front frame from the lower piece 42 3 is provided with a latching piece portion 43 extending upward at the front edge portion of the lower surface 3a, and a positioning piece portion 44 in which a part of the lower piece portion 42 is bent upward.
[0017]
The support piece 40 is integrally formed with the main body portion of the mounting plate 39 (a flat plate portion to which the drive motor 34, the striking rod 31 and the like are mounted), and the mounting plate 39 (including the ride-up means 60) is formed in the front An insertion hole 40a for inserting a wood screw to be fixed to 3 is formed. Further, the riding piece 41 is formed by an upper slope piece 41a and a lower slope piece 41b (an example of a guide part) that form a cross-sectional shape of a “<” shape protruding toward the back side of the front frame 3. The lower slope 41ba of the lower slope piece 41b forms a gentle slope (for example, about 30 degrees) upward with respect to the lower face 3a of the front frame 3 (see FIG. 8). The ride-up piece 41 does not necessarily have a cross-section “<” shape. As long as the lower surface 41ba of the lower inclined surface piece 41b forms a gently curved surface (for example, an inclined surface) upward with respect to the lower surface 3a of the front frame 3, for example, the upper inclined surface piece 41a may have any cross-sectional shape. .
[0018]
In addition, the positioning piece 44 bends a part of the lower piece 42 upward in the vicinity of the boundary line with the riding piece 41 so as to form the same plane as the support piece 40 (see FIG. 8). It is formed by. The mounting plate 39 and the support piece 40, the ride piece 41, the lower piece 42, the latch piece 43, and the positioning piece 44 that constitute the ride means 60 are made of, for example, a sheet metal sheet metal. It is integrally formed by processing.
[0019]
In contrast to the configuration on the front frame 3 side as described above, the guide member 50 is positioned on the upper surface 2a of the lower frame member 2 at a position corresponding to the ride-on means 60 when the front frame 3 is closed, as shown in FIG. Is detachably attached. This guide member 50 is an example of a guide means. As shown in FIG. 6, the guide member 50 has a flat plate-like upper piece 51 along the upper surface 2 a of the lower frame member 2, and obliquely downwards from the upper piece 51 to the front edge portion of the upper surface 2 a of the lower frame member 2. An extended guide piece portion 52 (an example of a guide portion) is provided, and is integrally formed by, for example, sheet metal processing of a single metal plate. The upper piece 51 is provided with an insertion hole 51a through which a wood screw for fixing the guide member 50 to the upper surface 2a of the lower frame member 2 is inserted. Further, the upper surface 52a of the guide piece 52 forms a slope whose angle with respect to the upper surface 2a of the lower frame member 2 is, for example, about 60 degrees (see FIG. 6). The guide member 50 is formed so that the lateral width (the length along the longitudinal direction of the lower frame member 2) is, for example, the same as or slightly longer than the lateral width of the mounting plate 39 of the launching device 13. Yes.
[0020]
Then, the procedure at the time of attaching the launching device 13 and the guide member 50 having the above-described riding means 60 to the front frame 3 and the lower frame material 2 will be briefly described. First, when attaching the launching device 13 to the front frame 3, the mounting plate 39 is first attached to a predetermined position below the front frame 3 with other components except the firing handle 35 attached to the mounting plate 39. . For example, the hooking piece 43 is hooked from the rear side of the front frame 3 to the lower edge of the front side at a predetermined mounting position of the lower end of the opening / closing end opposite to the hinge part 4 of the front frame 3 (solid line in FIG. 7). ). Then, as indicated by an arrow Y in FIG. 7, the mounting plate 39 is rotated until the support piece 40 comes into contact with the back side of the front frame 3.
[0021]
As a result, as shown in FIG. 7 by a two-dot chain line, the mounting plate 39 includes the latching piece portion 43, the lower piece portion 42, the positioning piece portion 44, and the support piece portion 40 that constitute the riding means 60. 3 is in contact with the corresponding surface. At this time, the lower slope piece 41b is located on the back side of the front frame 3 and forms a rearward obliquely upward slope. Note that the firing spring 32 and the mounting boss portion 36 (see FIG. 4) attached to the front surface (attachment surface to the front frame 3) side of the attachment plate 39 are in a through hole (not shown) formed in the front frame 3. Stored in In this state, if the wood screw is inserted into the insertion hole 40 a of the support piece 40 and screwed into the back surface of the front frame 3, the mounting plate 39 is fixed to the front frame 3. Further, the firing handle 35 is attached to the attachment boss portion 36 from the front side of the front frame 3 through the through hole. This completes the mounting of the launcher 13 having the ride-on means 60 to the front frame 3.
[0022]
Further, when the guide member 50 is attached to the lower frame member 2, a predetermined position (front frame 3) on the upper surface 2 a of the lower frame member 2 is set so that the guide piece 52 is inclined downward on the front side of the lower frame member 2. The upper piece 51 of the guide member 50 is brought into contact with the mounting plate 39 at a position corresponding to the position of the mounting plate 39 when the is closed. At this time, the bent portion between the upper piece 51 and the guide piece 52 may be positioned so as to be aligned with the front edge of the lower frame member 2. In this state, if the wood screw is inserted into the insertion hole 51 a of the upper piece 51 and screwed into the upper surface 2 a of the lower frame member 2, the guide member 50 is fixed to the upper surface of the lower frame member 2. This completes the attachment of the guide member 50 to the lower frame member 2.
[0023]
Next, an operation state at the time of opening and closing the front frame 3 in a state where the ride-on means 60 and the guide member 50 are attached will be described. When the front frame 3 is closed from the open state as shown in FIG. 2, the front frame 3 swings around the hinge portions 4 and 4 and finally reaches a position adjacent to the upper side of the lower frame material 2. . At this time, the lower surface 3a of the front frame 3 and the upper surface 2a of the lower frame member 2 are in an opposed state.
[0024]
Here, as described above, a large number of various parts are attached to the front frame 3, so that the weight thereof is extremely large. Therefore, an excessive load is applied to the hinge portion 4 when the front frame 3 is opened and closed. As a result, as the routine opening and closing of the front frame is repeated over a long period of time, the mounting backlash and the like of the hinge portion 4 gradually increase, and the opening and closing end side of the front frame 3 is in a state where it is hung relative to the hinge end side. There are many.
[0025]
When the front frame 3 is closed in such a state, as shown in FIG. 8, immediately before the front frame 3 is completely closed, the lower slope piece 41b of the riding piece 41 of the riding means 60 is guided. It abuts on the guide piece 52 of the member 50. When the front frame 3 is further closed from this state, the lower surface 41ba of the lower slope piece 41b slides on the guide piece portion 52, and the riding means 60 and the front frame 3 are inclined in the direction of the slope of the lower surface 41ba of the lower slope piece 41b. Is gradually lifted. After the ride-up means 60 has completely climbed on the guide member 50, the lower piece 42 of the ride-up means 60 slides on the upper piece 51 of the guide member 50, and accordingly the front frame 3 reaches the closed position. Moving.
[0026]
In this way, when the front frame 3 is closed, the lower slope piece 41b of the ride-up means 60 gradually rides on the guide member 50, so that the open / close end side of the front frame 3 hangs relatively from the hinge end side. Even in such a case, the impact due to the interference between the lower surface 3a of the front frame 3 and the upper surface of the lower frame member 2 becomes extremely small, and the closing operation of the front frame 3 can always be performed smoothly.
[0027]
On the other hand, when the front frame 3 in the closed state is opened, the movement is completely opposite to that in the above-described closing operation. That is, when the front frame 3 is opened from the closed state, after the lower piece 42 of the riding means 60 slides on the upper piece 51 of the guide member 50, the lower surface 41ba of the lower slope piece 41b is guided to the guide piece 52. While sliding upward, the mounting plate 39 and the front frame 3 gradually descend in the direction of the slope of the lower surface 41ba of the lower slope piece 41b.
[0028]
As a result, even when the opening / closing end side of the front frame 3 is in a state of hanging relative to the hinge end side, the lower slope piece 41b of the ride-up means 60 is guided by the guide member when the front frame 3 is opened. 50, it is possible to prevent the opening / closing end side of the front frame 3 from instantaneously dropping from the lower frame material 2, and to always perform the opening operation of the front frame 3 smoothly. Become.
[0029]
In addition, as described above, the opening and closing of the front frame 3 can always be smoothly performed without causing a large impact, so that each component attached to the front frame 3 is damaged by the impact when the front frame 3 is opened and closed. The problem is solved.
[0030]
Further, the ride-on means 60 is provided on the launching device 13 attached in the vicinity of the opening / closing end on the opposite side of the hinge part 4 on the front frame 3, and each of the attachment positions of the hinge part 4 and the ride-on means 60 is provided. Since there is a sufficient distance between them, the force acting on the ride-up means 60 and the guide member 50 that slides with the front frame 3 when the front frame 3 is opened and closed is minimized, and the ride-up means 60 and the guide member 50 are long. There is also an advantage that the life can be extended. However, the hinge 4 is not necessarily provided at the end of the front frame 3 opposite to the mounting position of the launching device 13, but the hinge 4 and the launching device 13 are both provided at one end of the front frame 3. You may provide in the vicinity of a part.
[0031]
Further, since the climbing means 60 is integrally formed with the mounting plate 39 of the launching device 13, the number of parts can be reduced and the assembly process can be simplified as compared with the case where the climbing means is provided separately from the launching device 13.
[0032]
FIG. 9 exemplifies the second embodiment of the present invention, and mounts the climbing means 61 (support piece 40, ride piece 41, lower piece 42, latch piece 43, and positioning piece 44). An example is shown in which the plate 39 'is formed as a separate member and fixed to the mounting plate 39' by screwing or welding. Thus, by using the climbing means 61 and the mounting plate 39 ′ as separate members, there is an advantage that, for example, the mounting plate 39 ′ can be shared by a model to which the riding means 61 is attached and a model to which the riding means 61 is not attached.
[0033]
10 and 11 illustrate a third embodiment of the present invention. For example, a wheel support 53 formed integrally with the mounting plate 39 ″ of the launching device 13 ″ and a horizontal axis with respect to the wheel support 53. An example is shown in which the ride-up means 62 is composed of wheels 54 that are rotatable around 54a. The wheel support 53 may be formed as a separate member from the mounting plate 39 ″ and fixed to the mounting plate 39 ″ by screwing or welding. Further, as shown in FIG. 11, for example, the wheel 54 is attached such that the position of the lowermost portion (bottom surface) thereof is substantially the same as or slightly lower than the lower surface 3 a of the front frame 3.
[0034]
When the front frame 3 is closed with the riding means 62 attached, as shown in FIG. 11, immediately before the front frame 3 is completely closed, the wheel 54 is placed on the guide piece 52 of the guide member 50. Abut. When the front frame 3 is further closed from this state, the wheel 54 rolls so as to ride on the slope of the guide piece 52, and the ride-on means 62 and the front frame 3 are gradually lifted obliquely upward. Then, after the riding-up means 62 has completely climbed on the guide member 50, the wheel 54 rolls horizontally on the upper piece 51 of the guide member 50, and eventually the rear end side of the upper piece 51 of the guide member 50. The wheel 54 is disengaged from the guide member 50. Thereafter, the lower surface 3a of the front frame 3 moves to the closed position while sliding horizontally on the upper piece 51 of the guide member 50. Further, when the front frame 3 in the closed state is opened, the movement is completely opposite to that in the above closing operation.
[0035]
As described above, even when the ride-up means 62 having the wheels 54 is used, as in the case of the first and second embodiments described above, the open / close end side of the front frame 3 hangs relatively from the hinge end side. Even when the front frame 3 is open / close, it is possible to perform the opening / closing operation of the front frame 3 smoothly without any significant impact, and each component attached to the front frame 3 Problems such as damage caused by impact can also be resolved.
[0036]
As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to this embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, when the mounting plate 39 is cast from a material such as an aluminum alloy, the ride-on means 60 can be cast integrally with the mounting plate 39. It is also possible to form the ride-on means 60 from another material such as iron by sheet metal and to integrate it by molding when casting the mounting plate 39 or to fix it to the cast mounting plate 39 by screws or the like. .
[0037]
Further, in the first and second embodiments, the example in which the riding means 60 and 61 are formed over the entire lower edge of the mounting plate 39 is not limited to this, but the lower edge of the mounting plate 39 is not limited thereto. The ride-on means 60, 61 may be formed only in a part thereof.
[0038]
Further, in the first and second embodiments, the example in which the ride-on means 60, 61 includes the latching piece portion 43 and the positioning piece portion 44 is shown, but either or both of them can be omitted. is there. Moreover, the lower piece part 42 does not necessarily need to be in contact with the lower surface 3a of the front frame 3, and a slight distance may be provided therebetween.
[0039]
Further, in the first and second embodiments, an example in which bent guide portions (the lower slope piece 41b and the guide piece 52 of the ride piece 41) are formed on both the ride means 60, 61 and the guide member 50. Although shown, these guide portions may be provided only on one of the ride-on means 60 and 61 and the guide member 50.
[0040]
In addition, the present invention can be similarly implemented not only in pachinko machines but also in ball game machines such as arrange ball machines and sparrow ball game machines.
[0041]
