Description

[0001]
[Industrial application fields]
The present invention relates to a launch rail that is a travel path of a game ball in a ball-type game machine such as a pachinko machine.
[0002]
[Prior art]
In pachinko machines, game balls are launched by being struck by a member called a spear. This launched game ball is guided to the play area by being guided by the guide rail, and the launch rail determines the trajectory of the game ball so that the game ball is inserted into the guide rail at an appropriate angle. . An example of a conventional firing rail is shown in FIG. FIG. 8A is a front view, and FIG. 8B is an EE cross-sectional view thereof.
[0003]
In the firing rail 81 shown in FIG. 8, the rail body 85, which is a portion where the game ball 83 travels, is attached to the support portion 87 while being inclined along the longitudinal direction. The game ball 83 is held at the end lowered by this inclination, and waits for it to be hit by a spear. Further, the rail body 85 is curved so as to be recessed downward in the longitudinal direction, and the game ball 83 that has been punched and runs on the rail body 85 and reaches the other end of the rail body 85 is guided by a guide rail (not shown). To fire at an optimal angle. Moreover, the rail body 85 is formed by bending a sheet metal so that the cross section is substantially M-shaped as shown in FIG. The game ball 83 travels in parallel with the longitudinal direction of the rail body 85 without meandering by traveling on the rail body 85 while being in contact with the two M-shaped slopes 89a and 89b.
[0004]
[Problems to be solved by the invention]
However, as described above, the rail body 85 of the launch rail 81 has a structure that is bent so that a cross section perpendicular to the traveling direction is substantially M-shaped, and is curved along the traveling direction. Therefore, manufacturing is extremely difficult. Therefore, the rail main body 85 may be damaged at the time of bending, and the yield of the rail main body 85 is deteriorated, and the cost of the firing rail 81 is increased. For the same reason, the rail main body 85 is distorted after manufacture, and the contact position between the basket and the game ball 83 is different, or the game ball 83 is thrown into the guide rail at an inappropriate angle. As a result, the ballistic trajectory of the game ball 83 released to the game area is disturbed, and there is a problem that the player's motivation is cut off.
[0005]
In addition, when the contact position of the spear and the game ball 83 becomes inappropriate, the spear is bent and adjusted with a special dedicated tool. However, in order to correct the contact position by this method, a high level of skill is required, and even after correction, the spear returns to the shape before correction as the game ball is ejected, and the contact position again. May change.
[0006]
Further, when the game ball 83 is inserted into the guide rail at an inappropriate angle, the guide rail is bent and the relative position with respect to the rail body 85 is adjusted. This is because the structure of the rail body 85 is difficult to bend as described above. However, this adjustment work also requires so-called craftsmanship, and for example, it is difficult for employees of pachinko halls to perform the same work.
[0007]
The present invention has been made in view of these problems, and an object thereof is to reduce the cost of the launch rail and to easily adjust the contact position between the kite and the game ball.
[0008]
[Means for Solving the Problems]
The invention according to claim 1, which has been made in order to achieve such an object, includes a holding portion that holds a game ball used in a ball-type game machine at an injection position thereof, and a traveling path of the injected game ball. In a launch rail for a ball-type game machine, comprising a rail body having a support portion supporting at least the rail body,
The rail body is
At one edge in the longitudinal direction, two long plates that are parallel to each other with a smaller interval than the game ball and in which the surfaces overlap each other at a portion including the edge opposite to the one edge there are a runner to the longitudinal travel path of the game ball directed upward direction to one edge of,
The該滑run portion have a fixing portion to be fixed to the support portion,
The sliding part is
It is a long plate-shaped member, with one edge in the longitudinal direction as a reference edge, bent in opposite directions along two fold lines parallel to the reference edge, and the edge opposite to the reference edge is A first rail piece formed in a curved shape with a concave center in the longitudinal direction;
A second rail piece formed in plane symmetry with the first rail piece;
The surfaces of the rail pieces including the reference edge are overlapped to fix the surfaces to each other .
[0014]
[Operation and effect of the invention]
In the launch rail for a ball-type game machine according to claim 1, the rail body has a sliding portion and a fixing portion for fixing the sliding portion. And the sliding part has two long board | plate materials erected in parallel with each other in one edge of the longitudinal direction . The interval between these two sheets is narrower than the diameter of the game ball. Accordingly, the game balls are run in contact with the upper edges of the two plates.
[0015]
As shown in FIG. 8 (b), the conventional rail body has a plate material bent into an M-shaped cross section, and further has a concave shape in the longitudinal center as shown in FIG. 8 (a). Was curved. In contrast, in the firing rails, not Runode is curved slide unit itself, two of the upper edge as the traveling position, can be formed in a curved shape recessed in the longitudinal direction of the center.
[0016]
Therefore, according to the first aspect of the present invention, since it is not necessary to perform a difficult process of bending the plate-like member into an M shape and further bending as in the past, the cost of the rail main body, and thus the launch rail, can be reduced. Can be lowered. Further, since the rail body is not distorted, it is possible to prevent the firing angle from becoming inappropriate and the contact position with the heel from changing.
[0017]
Invention of Claim 1 is implement | achieved by the simple structure that a sliding part superposes | stacks the following two plate-shaped members. That is, a first rail piece that is long and is bent at two locations along a fold line parallel to the longitudinal direction thereof, and a second rail piece that is formed symmetrically with the first rail piece. These are two plate-like members. Each rail side is divided into three surfaces perpendicular to the longitudinal direction by being bent at two points. Of these three surfaces, the sliding portion is formed by superimposing and fixing one surface at the end. Then, the central surfaces that are not used for fixing are bent so as to be separated from each other, and the remaining one surface is extended at a predetermined interval. That is, each remaining one surface becomes two long plate members, and each upper edge thereof becomes a place where a game ball is run.
[0018]
Therefore, according to the invention described in claim 1 , since the sliding portion has a simple configuration in which the two rail pieces are superposed and fixed, the production is extremely easy. That is, in order to form the two long plate members of the sliding portion, it is not necessary to cut the long material while securing the interval or to cast the entire sliding portion, and it is very easy to manufacture. .
[0019]
Moreover, since it is the structure which superposed | stacked two rail pieces with the bending line along a longitudinal direction, it is robust. Therefore, in the conventional firing rail 81 (see FIG. 8), the core 91 is used to reinforce the inside of the M-shaped cross section. However, the core 91 is not necessary in the present firing rail.
[0026]

The coupling plate 57 is provided with a long hole 59 for fixing the holding portion 17 to the support portion 19, and the sliding plate 53 is formed with a slit-like narrow groove 61.
[0034]
The procedure for assembling the above-described parts to form the firing rail will be described with reference to FIG. First, adjustment screws 63 and 63, each having a flange-like member (hereinafter simply referred to as a flange) provided around the side of the head, are tightened into the tap holes 44a and 44b of the support portion 19. In addition, the diameter of this collar part is made equal to the width | variety C (refer FIG. 3) of the fitting holes 37a and 37b of the fixing | fixed part 15. FIG. Then, the fixing portion 15 is mounted on the projecting pieces 41a to 41c while fitting the flange portions of the adjusting screws 63 and 63 into the fitting holes 37a and 37b, and the three screws 65 are screwed into the tap holes 45a to 45c to fix the fixing portion 15 to each other. Is fixed to the support portion 19. Unlike the adjustment screw 63, this screw 65 is a normal screw in which no collar portion is formed.
[0035]
Next, the adjusting screws 63 and 63 are tightened into the tap holes 33 a and 33 b of the fixing portion 15. The surface 31 of the fixing portion 15 and the reference surface 25 of the sliding portion 13 are overlapped while fitting the flanges of the adjusting screws 63, 63 into the slots 27a, 27b, and the three screws 65 are screwed into the tap holes 35a-35c. The sliding part 13 is fixed to the fixing part 15 together.
[0036]
The adjustment screw 63 tightened in the tap holes 33a and 33b corresponds to a screw for moving the sliding portion 13 relative to the fixed portion 15 of the present invention, and is adjusted in the tap holes 44a and 44b. The screw 63 corresponds to a screw for moving the fixed portion 15 relative to the support portion 19 of the present invention. That is, in the launch rail 1, the same thing is used for both the adjustment screws, and therefore, the flange portion of the adjustment screw 63 that is tightened into the tap holes 33a and 33b is used as the flange member of the present invention. Correspondingly, the flange portion of the adjusting screw 63 that is tightened into the tap holes 44a and 44b corresponds to the cam of the present invention.
[0037]
Then, when the holding portion 17 is fixed to the position of the guide portion 47 of the support portion 19 with the screw 65, the appearance as the firing rail 1 is adjusted, and the sliding portion 13 is installed to be inclined upward as shown in FIG. It becomes a state, and it becomes possible to hold | maintain the game ball 11 in the edge part made low by this inclination. In order to complete the launch rail 1, the mounting position of the holding portion 17 is adjusted so that the holding position of the game ball 11 is appropriate, and the game ball 11 is fired from the sliding portion 13 at an appropriate angle. In addition, it is necessary to adjust the angle of the sliding portion 13.
[0038]
First, a method for adjusting the mounting position of the holding portion 17 will be described with reference to FIG. FIG. 6A is a front view of a state in which the holding portion 17 is temporarily attached, FIG. 6B is a plan view thereof, and FIG. 6C is an explanatory view showing how the attachment position is changed.
The holding part 17 is fixed by screwing the screw 65 into the tap hole 46 (see FIG. 4) through the washer 66 and the long hole 59. In this fixing, the sliding plate 53 is in contact with the guide portion 47 and the coupling plate 57 is in contact with the plate surface of the support portion 19. Thus, the holding portion 17 is fixed so as to be movable only in the vertical direction in the drawing. Note that the narrow groove 61 is formed so that the narrow groove 61 formed in the sliding plate 53 and the notch 49 of the guide portion 47 substantially coincide with each other when the holding portion 17 is fixed at an appropriate position. .
[0039]
Since the moving amount of the holding unit 17 greatly affects the holding position of the game ball 11, it is necessary to carefully carry out each minute, but this can be done as follows. That is, when the holding portion 17 is moved, first, a thin flat plate-like object (for example, the tip 67 of a negative screwdriver) is inserted into the slit portion in which the notch 49 and the narrow groove 61 are communicated with each other. Next, the screw 65 is loosened and the screwdriver tip 67 is slowly rotated (for example) counterclockwise. Then, as shown in FIG. 6C, the tip 67 pushes down the narrow groove 61 downward. If the amount of movement is insufficient, a flat plate thinner than the tip 67 may be used to rotate it further, and if it is desired to move the holding portion 17 in the opposite direction, the tip 67 may be operated clockwise. In this way, the holding part 17 is moved to a desired position, and the screw 69 is fastened and re-fixed. Thereby, adjustment of the attachment position with respect to the support part 19 of the holding | maintenance part 17 is completed.
[0040]
On the other hand, the adjustment position of the sliding portion 13 with respect to the fixing portion 15 is adjusted using the adjusting screw 63. This method will be described with reference to FIG. Fig.7 (a) is the figure which expanded the periphery of the slot 27a in Fig.1 (a), FIG.7 (b) is the DD sectional drawing. As described above, the adjustment screw 63 is provided with the flange portion 71, and the diameter thereof is substantially equal to the width B of the slot 27a. In the adjustment screw 63, the flange 71 is provided eccentrically.
[0041]
In order to adjust the tip position of the sliding portion 13 up and down, first, the screw 65 is loosened appropriately to allow the sliding portion 13 to move up and down, and then the adjustment screw 63 is rotated. Then, the collar part 71 is rotated in the slot 27a, and the outer peripheral surface of the collar part 71 pushes the inner circumference of the slot 27a upward or downward. For example, the slot shown by a solid line in FIG. 27a is moved to a slot 27a 'indicated by a two-dot chain line. That the slot 27a moves up and down means that the sliding portion 13 moves relative to the fixed portion 15 as indicated by 13 'indicated by a two-dot chain line. After the tip of the sliding portion 13 is thus set to a desired height, the screw 65 is tightened to fix the sliding portion 13 to the fixed portion 15.
[0042]
As described above, the tip of the sliding portion 13 can be easily moved up and down with respect to the fixed portion 15 by screwing. In addition, when moving the rear part position of the sliding part 13 up and down, it can carry out by rotating the adjustment screw 63 fastened by the tap hole 33b.
[0043]
Further, when it is desired to move the sliding portion 13 in the front-rear direction of FIG. 1A, the adjustment is similarly performed using the adjustment screw 63 tightened in the tap holes 44a and 44b. That is, the screws 65 (those tightened in the tap holes 45a to 45c) are loosened appropriately to make the fixing portion 15 movable in the front-rear direction, and then the adjustment screws 63 (tightened in the tap holes 44a and 44b). ). Then, the collar part 71 is rotated in the fitting holes 37a and 37b, and the outer peripheral surface of the collar part 71 pushes the inner circumference of the fitting holes 37a and 37b forward or backward, whereby the fixing part 15 is moved to the support part 19. Move against. After moving the fixing portion 15 to a desired position in this way, the screws 65 (those tightened in the tap holes 45 a to 45 c) are tightened to fix the fixing portion 15 to the support portion 19. When the adjustment is completed in this way, the firing rail 1 is completed.
[0044]
The game ball 11 struck by the kite at the holding position of the launch rail 1 travels along the edge 23 of the sliding portion 13. This is because, as described above, the width of the sliding portion 13 is shorter than the diameter of the game ball 11, and the game ball 11 travels while being supported by the two edges 23 and is fired from the tip of the sliding portion 13. Is done. Since the traveling path of the conventional launch rail has curved the entire rail body, a difficult processing step is required. However, according to the launch rail 1, for example, two rail pieces 13a and 13b are superposed. Since the edge 23 may be cut into a curved shape as shown in FIG. 2 etc., the processing is easy.
[0045]
Moreover, since the sliding part 13 has the structure which superposed | polymerized the rail pieces 13a and 13b which have a fold line along a longitudinal direction, it is robust. In the conventional launch rail 81 (see FIG. 8), the core 91 is used to reinforce the inside of the M-shaped cross section. However, the core 91 is unnecessary in the sliding portion 13.
[0046]
Further, the launch rail 1 can adjust the holding position of the game ball 11 by changing the mounting position of the holding portion 17, and move the sliding portion 13 up and down and forward and backward with respect to the support portion 19. In addition, both can be performed very easily by using a screwdriver or the like. Therefore, it does not require special skills such as bending a ridge or a special tool.
[0047]
The launch rail 1 according to an embodiment of the present invention has been described above, but the present invention is not limited to the above-described configuration, and can be implemented in various modes.
For example, the rail pieces 13a and 13b are made of stainless steel, but may be made of other metals or ceramics.
