[Industrial application fields]
The present invention relates to a component mounting structure in a gaming machine, for example, a mounting structure such as a winning device attached to a game board of a pachinko machine.
[0002]
[Prior art]
For example, on a game board of a pachinko machine, many components such as a winning device such as a variable winning device called an attacker and decorative parts are attached. As an attachment structure for attaching these component parts to the game board, an insertion hole into which the component part can be inserted is opened on the surface of the game board, and a screw hole is provided around the insertion hole. 2. Description of the Related Art A structure in which a through hole through which a screw or a screw is passed is provided at a position corresponding to a screw hole of a game board, and the component and the game board are fastened with a screw or a screw is widely known. In this mounting structure, it is necessary to accurately align the screw holes of the game board and the through holes of the component parts. Must be inserted. Also, when removing the components from the game board, the screws and screws must be removed one by one. Thus, in the mounting structure using screws and screws, there is a problem that it is not easy to attach and detach the component parts to the game board.
[0003]
Therefore, without using a screw, a claw-like locking piece is projected on the back side of the component, and the component can be attached to and detached from the game board by fitting this locking piece into the mounting hole established in the game board. A structure to be attached to is known (for example, Japanese Utility Model Publication No. 5-30453). According to this structure, the component can be easily attached to a predetermined position of the game board, and the component parts can be elastically deformed by applying force to the locking pieces of the component parts attached to the game board. It can be removed from the game board.
[0004]
[Problems to be solved by the invention]
However, in the mounting structure that enables attachment / detachment to the component parts by the locking piece provided on the back side of the component parts as described above, if the component parts are large, the structure is to ensure the mounting to the game board. Locking pieces must be provided at several locations on the part. For this reason, when removing the component parts, it is required that the locking pieces are elastically deformed and removed from the game board by putting fingers or using tools on the locking pieces at the plurality of locations. Therefore, there is a problem that the larger the component parts and the greater the number of locking pieces, the more complicated the removal work and the longer the time.
[0005]
An object of the present invention is to provide a mounting structure in which components attached to a game board by a plurality of locking pieces are more easily attached to and detached from the game board.
[0006]
[Means for Solving the Problems]
The present invention provides a structure for attaching a component to a gaming board of a gaming machine, wherein the component is provided with a plurality of elastic locking portions that are engaged with a peripheral edge portion of an insertion hole formed in the gaming board. At least one of the stop portions is formed as a specific locking portion in which a region that contacts the peripheral portion of the insertion hole decreases as the locking portion moves when the component is removed from the attached state. Features.
[0007]
In a specific aspect of the present invention, the region in contact with the peripheral portion of the insertion hole is a part of the end surface of the protruding portion that protrudes outward from the tip of the specific locking portion, and the end surface is a component. The flat portion that contacts the peripheral portion of the insertion hole when attached to the game board, and the peripheral portion of the insertion hole as the specific locking portion moves when the component is removed from the attached state. It is comprised with the curved surface part formed following the plane part.
[0008]
In the present invention, one insertion hole of the game board is provided for each component, and a plurality of engaging portions of the component are engaged with the insertion hole. A plurality of through holes or recessed holes can be provided as insertion holes of the game board corresponding to the stop portions. When the gaming machine is a pachinko machine, examples of the component include a winning device such as the attacker.
[0009]
[Action and effect]
According to the present invention, when a component is attached to the gaming board of the gaming machine, the component can be quickly and easily engaged by elastically engaging the locking portion of the component with the peripheral edge of the insertion hole of the gaming board. Mounted accurately.
[0010]
When removing the components mounted on the game board, elastically move any locking part other than the specific locking part formed so that the area contacting the peripheral part of the insertion hole of the game board decreases. When it is deformed and pulled in the direction of removal, the specific locking portion also moves. At this time, since the area where the specific locking portion contacts the peripheral portion of the insertion hole is reduced according to the movement, the resistance force due to the contact between both is gradually reduced. For this reason, the specific locking part can be removed from the insertion hole by simply pulling out the arbitrary locking part from the insertion hole of the game board, and even a component mounted on the game board by a plurality of locking parts is small. It can be easily and easily removed from the game board by force.
[0011]
Therefore, when replacing the components on the game board of the gaming machine, the game board and the old and new components are not damaged with a great force, and the time required for the replacement can be shortened as compared with the prior art.
[0012]
In a specific aspect of the present invention, when the component is attached to the game board, the flat portion of the end face of the projecting portion projecting outward from the tip of the specific locking portion is the peripheral portion of the insertion hole of the game board. When the component parts are in contact with each other and removed from the attached state, the region that contacts the peripheral portion of the insertion hole of the game board moves from the flat surface portion of the end surface to the curved surface portion as the specific locking portion moves. As a result, the contact area gradually decreases, and when the contact area becomes zero, the specific locking portion is disengaged from the insertion hole of the game board. That is, since the contact area decreases while gradually shifting from the flat surface portion to the curved surface portion, the component parts can be easily and smoothly removed.
[0013]
Further, according to the present invention, when one insertion hole of the game board is provided for the component part and the plurality of locking portions of the component part are engaged with the insertion hole, The attachment and detachment can be performed with one touch, and the type and the attachment position of the component parts can be recognized at a glance with the shape and size of the insertion hole.
[0014]
Furthermore, when a plurality of through holes or recessed holes are provided in the game board as insertion holes for the plurality of locking parts of the component parts, the positions of the locking parts are made common regardless of the type and shape of the component parts. If so, a desired one of the plurality of components can be attached to and detached from the insertion hole of the game board. In this case, it is not necessary to use all of the plurality of through holes or recessed holes of the game board, and appropriate ones can be used according to the size and shape of the component parts.
[0015]

As shown in FIG. 2, the locking portion 14 includes an inclined surface 16 inclined upward from the tip 12 of the locking piece 4, a protruding end surface 17 formed at the upper end portion thereof, and a locking piece from the protruding end surface 17. 4 is formed so that the distance from the surface of the substrate 10 forming the base of the locking piece to the end surface 18 substantially matches the thickness of the game board 20 described later. Has been.
[0017]
However, in this embodiment, only the left and right locking pieces 3 and 4 are formed to have locking portions (specific locking portions) having specific shapes as described below. Below, the locking piece 4 on the right side of FIG. 1 will be described.
[0018]
As shown in FIG. 2, the locking portion (specific locking portion) 14 of the locking piece 4 is formed in a shape whose width gradually narrows from the tip 12 along the inclined surface 16. For this reason, the protruding end surface 17 of the locking portion 14 is composed of a flat surface portion 17a located at the upper end of the inclined surface 16, and an inclined surface portion 17b inclined along the front side of the inclined surface 16 and continuing to the flat surface portion 17a. Corresponding to the flat surface portion 17a and the inclined surface portion 17b of the inclined surface 16, the end surface 18 also includes a flat surface portion 18a and a curved surface portion 18b. Due to these shapes, the contact area of the locking portion 14 that contacts the back surface portion surrounding the insertion hole 22 provided in the game board 20 as described later is used to move the locking portion 14 when the component 1 is removed. Along with this, as indicated by the hatched portion 19 of the end face 18, it rapidly decreases.
[0019]
FIG. 3 shows a portion of the gaming machine 20 such as a pachinko machine where an insertion hole 22 is formed in the gaming board 20 to which the component 1 is mounted. The insertion hole 22 includes a substantially rectangular opening having four corners formed as slopes.
[0020]
FIG. 4 is an enlarged view showing the relationship between the locking piece 4 and the insertion hole 22 of the game board 20. When the component 1 is attached to the game board 20, as shown by the arrows, the locking portion 14 of the locking piece 4 protruding from the component 1 is inserted from the front surface 20 A side of the game board 20 to the peripheral portion of the insertion hole 22 ( (Inner wall surface) 24 is inserted. At this time, since the locking portion 14 is pushed inside the insertion hole 22, the locking piece 4 is elastically deformed. Further, when the locking part 14 comes out from the insertion hole 22 of the game board 20 to the back surface 20B side by pressing the component 1, the locking piece 4 returns from the deformed state to the original state, and the locking part 14 Is locked to the peripheral edge 24 of the insertion hole 22.
[0021]
FIG. 5 is a longitudinal sectional view showing this locked state. At this time, the end surface 18 of the locking portion 14 protruding to the back surface 20B side of the game board 20 contacts the periphery of the insertion hole 22, and the flat portion 18a of the end surface 18 contacts the peripheral portion of the insertion hole 22 of the game board 20. It is an area.
[0022]
Next, the operation of the component mounting structure of the embodiment will be described.
[0023]
First, when the component 1 is attached to the game board 20, the locking portion 14 is inserted by pushing the inclined surface 16 at the tip of the locking piece 4 along the peripheral edge 24 of the insertion hole 22 in the direction of the arrow in FIG. 4. It is easily pulled into the hole 22. Then, as described above, when the locking portion 14 comes out from the insertion hole 22 of the game board 20 to the back surface 20B side, the flat portion 18a of the end surface 18 of the locking portion 14 is around the insertion hole 22 of the game board 20 ( The game board 20 is sandwiched between the contact area of the flat surface portion 18 a and the back surface of the substrate 10. The same applies to the other locking pieces. Thus, the component 1 is locked on the game board 20 with all the locking pieces in contact with the peripheral portion of the insertion hole 22.
[0024]
Next, the case where the component 1 mounted on the game board 20 is removed as described above will be described.
[0025]
First, in the state of FIG. 5, of the plurality of locking pieces other than the left and right locking pieces 3 and 4 (for example, when removing the component 1 by pulling it upward on the back surface 20B side of the game board 20) , The lower locking pieces 7 and 8 are described below in this case), and the locking portions 7 and 8 are elastically deformed by pushing the locking portion 14 in the inner direction of the insertion hole 22. Next, as shown in FIG. 6, the lower part of the substrate 10 is pulled out, and the component 1 is rotated in the direction of the arrow with the upper locking pieces 5 and 6 as fulcrums. At this time, the lower locking pieces 7 and 8 move to the front surface 20 </ b> A side of the game board 20 while the locking portions 14 are in contact with the peripheral edge 24 of the insertion hole 22.
[0026]
On the other hand, as shown in FIG. 7, the left and right locking pieces 3, 4 rotate counterclockwise with the end surface 18 of the locking portion 14 as a fulcrum, so that they are in contact with the back surface 20 </ b> B of the game board 20. The area of the stop portion 14 gradually moves from the flat surface portion 18a of the end surface 18 to the curved surface portion 18b as shown by the hatched portion 19 in FIG. 2, and finally on the boundary line between the curved surface portion 18b and the inclined surface portion 17b. At the position 18 c, the width of the hatched portion 19 that is the contact area of the locking portion 14 becomes zero, and the end surface 18 of the locking portion 14 is detached from the back surface 20 </ b> B of the game board 20.
[0027]
Thus, when the component 1 is removed from the attached state, the area where the locking portions 14 of the left and right locking pieces 3 and 4 are in contact with the peripheral portion of the insertion hole 22 of the game board 20 Since it is formed so as to decrease suddenly as it rotates, it is possible to lock the left and right by simply pulling out the locking pieces other than the left and right locking pieces 3 and 4 from the insertion hole 22 of the game board 20 to the surface 20A side. The pieces 3 and 4 are also pulled out from the insertion hole 22.
[0028]
Therefore, even if the plurality of locking pieces 3 to 8 are provided on the component 1, the shape of the locking portions 14 of some of the locking pieces corresponds to the removal direction of the component 1 as described above. By forming the contact area so as to decrease rapidly, the component 1 can be easily removed.
[0029]
Next, FIG. 8 is a diagram showing the positional relationship between the locking piece 4 and the insertion hole 22 of the game board 20 when the thickness A of the tip 12 of the locking piece 4 is thinner than the thickness B of the plane portion. is there. In this case, since the wall surface of the peripheral edge 24 shown by the broken line is located above the tip 12 of the locking piece 4 in the drawing, the locking piece 4 is moved horizontally to the left in the drawing and the insertion hole 22 is formed. When being engaged with the peripheral edge 24, the tip 12 enters the insertion hole 22. Then, as the locking piece 4 moves, the corner 25 of the peripheral edge 24 relatively moves along the inclined surface 16 of the locking piece 4, so that the locking operation is performed smoothly.
[0030]
On the other hand, as shown in FIG. 9, when the thickness A ′ of the tip 12 of the locking piece 4 is the same as the thickness B of the plane portion, the wall surface of the peripheral edge 24 indicated by a broken line is the engagement piece 4. It coincides with the position of the upper corner of the tip 12 of. For this reason, when the locking piece 4 is moved horizontally to the left in the figure and locked to the peripheral edge 24 of the insertion hole 22, there is a case where locking cannot be performed due to a slight difference between A ′ and B. Therefore, in the actual locking piece, it is preferable to make the dimension of B larger than A as in the example of FIG.
[0031]
In addition, the shape of the latching | locking part 14 of each latching piece is not restricted to said thing, A suitable change is possible. For example, in the state of FIG. 5, it is also possible to rotate the upper end side with the lower end side of the substrate 10 as a fulcrum. In this case, the shape of the locking portion can be formed as shown in FIG. . In this locking piece 4 ′, the curved surface portion of the end surface 18 ′ that contacts the peripheral portion of the insertion hole 22 of the game board is together with the protruding end surface 17 ′ formed at the upper end portion of the inclined surface 16 ′, as in the example of FIG. It has a shape that draws a gentle arc toward the opposite side.
[0032]
Further, FIG. 11 shows a locking piece having a shape that can be easily removed by rotating the component 1 in either the upper or lower direction on the back side of the game board 20. In this locking piece 4 ″, an end surface 18 ″ that contacts the peripheral portion of the insertion hole 22 of the game board is a protruding end surface 17 ′ formed at the upper end portion of the inclined surface 16 ′ on both sides of the central plane portion. In addition, a curved surface portion having a gentle arc shape is provided.
[0033]
Further, when the component 1 mounted on the game board is rotated and removed from the left end or the right end thereof, the shape like the above-described locking portion is changed to the locking pieces 5 and 6 on the upper side of the board 10 and the locking pieces on the lower side. It may be provided on the pieces 7 and 8. When the number of the locking pieces is large, among the locking portions having various shapes as described above, a locking portion having an optimal shape may be provided according to the removal direction of the component parts.
