Description

  In the assembly structure configured to include the first component member and the second component member assembled thereto, the assembled state of the first component member and the second component member is released. It is related with the assembly state cancellation | release prevention mechanism which blocks | prevents.

  In general, various consumer devices are not composed of only a single component, and in most cases, are constructed by assembling a plurality of components.

  Therefore, as described above, an apparatus constructed by assembling a plurality of components (hereinafter referred to as an assembly structure) has an assembly structure from the viewpoint of ensuring safety and preventing unauthorized modification, for example. A mechanism that prevents the assembled state of the first component member and the second component member assembled to the first component member among the plurality of component members constituting the object from being released (hereinafter referred to as an assembled state release prevention mechanism). There is something to prepare. Specifically, for example, in the field of gaming machines such as slot machines and pachinko machines, there is an unsealing prevention mechanism that prevents unsealing of the board case that houses the main control board that controls the overall operation of the gaming machine. is there.

  By the way, as the opening prevention mechanism as described above, for example, as described in Patent Document 1, a cylindrical member is provided in each of the case main body and the lid member to be assembled thereto, and solid pins are provided on these cylindrical members. 2. Description of the Related Art Conventionally, a lid opening prevention mechanism that prevents relative displacement between a case main body and a lid member by fitting is known.

  However, in the lid opening prevention mechanism as described in Patent Document 1, each component member constituting the substrate case is made of polycarbonate (so that the unauthorized action to the control board accommodated in the substrate case can be easily confirmed from the outside. It is generally formed of a transparent synthetic resin material such as PC). Then, the cylindrical member provided in each of the case main body and the lid member is also integrally formed with the case main body and the lid member with the same material as the case main body and the lid member in most cases from the relationship with the production efficiency and the like. It is like that. As a result, a dimensional error may occur in these cylindrical members during molding.

  In addition, depending on the ambient temperature of the substrate case, the cross-sectional shape and size of the central hole in the direction perpendicular to the axis of the cylindrical member provided in each of the case body and the lid member may change.

  Therefore, in the lid opening prevention mechanism described in Patent Document 1, it is difficult to fit the solid pins into both cylindrical members, or the solid pins can be fitted into both cylindrical members. Even if the solid pin is easily pulled out, or even if the solid pin is fitted and fixed to at least one of both cylindrical members, the solid pin may be removed due to a change in the ambient temperature of the board case. There is a possibility that it will be easy to come off, and it may be difficult to fully exhibit the function as a lid opening prevention mechanism.

  In addition, in the assembly structure, from the viewpoint of maintenance, inspection, etc., the assembly state release prevention function by the assembly state release prevention mechanism is not exhibited, and the first component member and the second component member are assembled. It may be necessary to cancel the attached state. Specifically, for example, in a board case that houses a main control board that controls the overall operation of the gaming machine, maintenance and inspection of the main control board housed therein is performed.

  Therefore, it is conceivable that a plurality of lid opening prevention mechanisms are provided for the substrate case, and the substrate case can be opened a plurality of times by using one of the plurality of lid opening prevention mechanisms.

  By the way, when a plurality of lid opening prevention mechanisms are provided in the substrate case and only one of these plurality of lid opening prevention mechanisms is used, once the substrate case is opened, the lid opening prevention mechanism used until then is used. Since it is common to be impossible, it becomes necessary to use the remaining unused lid opening prevention mechanism.

  Then, in order to fully exhibit the function in the lid-opening prevention mechanism to be used, solid pins are fitted to both cylindrical members as in the case of the lid-opening prevention mechanism used until the substrate case is opened. There is a need.

  Therefore, the first solid pin fitting work is performed at a manufacturing factory or the like, but the subsequent solid pin fitting work is most often performed in a game hall or the like where a gaming machine is installed. It is common. Therefore, since the person who performs the work of fitting the solid pin is not necessarily used to the work, there is a possibility that it is difficult to perform the work quickly, or the solid pin is attached to both cylindrical members. If the fitted state becomes insufficient, the function as an opening prevention mechanism may not be sufficiently exhibited.

JP 2005-342193 A

  Here, the present invention has been made against the background as described above, and the solution is to include the first component member and the second component member assembled thereto. To provide an assembly state release prevention mechanism having a novel structure that can advantageously prevent the assembly state of the first component member and the second component member from being released in the assembly structure. is there.

  In addition, the present invention provides a new structure assembly that can advantageously perform the work for exerting the intended assembly state release prevention function when the unused assembly state release prevention mechanism is used. It is another object of the present invention to provide an attached state release prevention mechanism.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  The present invention provides a set of a first component member and a second component member in an assembly structure including the first component member and a second component member assembled to the first component member. An assembly state release preventing mechanism for preventing the release of the attached state, the first cylindrical part integrally formed with one of the first component member and the second component member, and the first component member, The second cylindrical part integrally formed with the other of the second constituent members is in a releasing direction for releasing the assembled state under the assembled state of the first constituent member and the second constituent member. The first cylindrical portion and the second cylindrical portion are positioned so as to be connected to each other in a direction intersecting with the second cylindrical portion. Insert it through the opening on the opposite side and fit it into the first tube part. By inserting the spring pin until the leading end portion that precedes when entering is in the internal space of the second cylindrical portion, a fixed state in which the first component member and the second component member are fixed is realized. On the other hand, an insertion protrusion that protrudes in the thickness direction from the center portion of the plate-like piece is inserted and fixed at the end of the spring pin opposite to the preceding end, and the first component member and the second component In a state where the fixed state in which the constituent members are fixed is realized, the plate-like piece is locked to the opposite side to the insertion direction of the spring pin with respect to the first tube portion, and further, the first tube portion An operating projection provided so as to protrude from the center portion of the plate-shaped piece to the other side in the plate thickness direction in a state where the spring pin is fitted to the plate-shaped piece and accommodated in the internal space of the first cylindrical portion. Is located on the opposite side of the first tube portion from the second tube portion When the projection is protruded from the end face of the mouth and the operation projection is formed separately from the plate-shaped piece, and external force is exerted on the operation projection in the spring pin insertion direction, While the projection is assembled to the plate-shaped piece, when an external force is applied to the operation projection in the direction opposite to the spring pin insertion direction, the operation projection is removed from the plate-shaped piece. It is characterized by having done.

  In the assembly state release prevention mechanism having such a structure according to the present invention, the first configuration member and the second configuration member constituting the assembly structure are assembled in the first configuration. Position the first cylindrical part and the second cylindrical part so that the internal spaces of the first cylindrical part and the second cylindrical part are connected in a direction that intersects the release direction for releasing the assembled state of the member and the second component member. The spring pin is inserted into the first tube portion from the opening opposite to the second tube portion in the first tube portion, and is fitted into the first tube portion. Since the spring pin is inserted until it reaches the interior space of the second cylindrical portion, a fixed state in which the first component member and the second component member are fixed is realized. The first component and the second component Displacement in the release direction is to be prevented by a spring pin.

  Therefore, in the present invention, since the spring pin is fitted to the first cylindrical portion, an external force in the direction perpendicular to the axis, that is, an external force in the direction of tightening the spring pin is exerted on the spring pin. The cross section of the spring pin in the direction perpendicular to the axis is deformed.

  As a result, it is possible to apply a force for the spring pin to return to its original shape, that is, a restoring force based on a spring action in the direction perpendicular to the axis of the spring pin itself to the first cylindrical portion. When the pin is displaced in the direction of coming out of the first cylindrical portion, it is generated between the outer peripheral surface of the spring pin and the inner peripheral surface of the first cylindrical portion, and acts in a direction that hinders the displacement of the spring pin. The frictional force can be advantageously ensured. As a result, it is possible to avoid problems caused by dimensional errors during the molding of the first cylindrical portion, and to maintain a good fixed state between the first component member and the second component member. Can be advantageously realized.

  In the present invention, the restoring force based on the spring action in the direction perpendicular to the axis of the spring pin itself can be exerted on the first tube portion on which the spring pin is fitted. From, for example, even when the cross-sectional shape or size in the direction perpendicular to the axis of the internal space in the first cylindrical portion changes with changes in the ambient temperature of the assembled structure, the spring pin itself A restoring force based on the spring action in the direction perpendicular to the axis can be exerted on the first cylindrical portion.

  As a result, when the spring pin is displaced in the direction of detaching from the first cylindrical portion, the frictional force acting in the direction that hinders the displacement of the spring pin, that is, the outer peripheral surface of the spring pin and the inner peripheral surface of the first cylindrical portion. It is possible to advantageously secure the frictional force generated between the two. As a result, it is possible to avoid the trouble caused by the change in the ambient temperature of the assembled structure, and to favorably maintain the first component member and the second component member in a good fixed state, and thus the assembled state. It can be realized.

  Furthermore, in the present invention, the plate-shaped piece is locked to the opposite side to the insertion direction of the spring pin with respect to the first cylindrical portion in the fixed state of the first component member and the second component member. As a result, the displacement of the spring pin in the direction opposite to the insertion direction is prevented. As a result, it is possible to more advantageously realize a good fixed state of the first component member and the second component member, and further maintenance of the assembled state.

  Therefore, in the assembly state release prevention mechanism of the present invention, it is possible to advantageously prevent the assembly state of the first component member and the second component member constituting the assembly structure from being released. Become.

  In the present invention, the spring pin is fitted into the first cylindrical portion, and the plate-like piece is accommodated in the internal space of the first cylindrical portion, and the plate is removed from the central portion of the plate-like piece. Since the operation protrusion provided to protrude in the other side in the thickness direction is protruded from the opening end surface located on the opposite side of the second cylinder part in the first cylinder part, the plate By appropriately setting the projection height of the operation projection from the other surface in the plate thickness direction of the plate-like piece, the plate-like piece is on the opposite side to the spring pin insertion direction with respect to the first cylindrical portion. The locked state, that is, the fixed state in which the first component and the second component are fixed, is achieved by simply pressing the operating protrusion in the spring pin insertion direction without using a special tool. It becomes possible to do.

  Therefore, in the assembly state release prevention mechanism of the present invention, when the unused assembly state release prevention mechanism is used, an operation for exerting the intended assembly state release prevention function, that is, assembly It is possible to advantageously perform an operation for setting the state release prevention mechanism to the use state.

  In particular, in the present invention, the operation protrusion is provided so as to protrude from the center portion of the plate-shaped piece to the other side in the plate thickness direction, and the insertion protrusion to be inserted and fixed to the spring pin is formed from the center portion of the plate-shaped piece. Since it is formed so as to protrude in one direction in the thickness direction, it is possible to exert a pressing operation force on the operation projection on the center axis of the spring pin, and as a result, the insertion work of the spring pin can be performed efficiently. Become.

  In the present invention, the assembly structure may be composed of only the first component member and the second component member, or in addition to the first component member and the second component member, A member may be provided. In addition, the material for forming the first component member and the second component member is not particularly limited, but from the viewpoint of (1) light weight and (2) excellent workability. A synthetic resin material is preferably employed. In particular, when a transparent synthetic resin material such as polycarbonate (PC) is employed, for example, the accommodation space formed by assembling the first component member and the second component member can be viewed from the outside. Easy to do.

  In the present invention, the assembled state refers to a state in which the first component member and the second component member can be handled integrally, and the fixed state refers to the first component member. The state in which the assembly state of the second component member is prevented from being released shall be said.

  Furthermore, in the present invention, each of the first tube portion and the second tube portion may be one or two or more. Furthermore, in the present invention, "the state in which the respective internal spaces of the first cylinder part and the second cylinder part are connected" means that the spring pin straddles the first cylinder part and the second cylinder part. A state that can be inserted. In that case, the 1st cylinder part and the 2nd cylinder part may overlap, and it may be made to be spaced apart with an appropriate space | interval.

  In the present invention, the cross-sectional shape in the direction perpendicular to the axis of the internal space in the first cylindrical portion or the second cylindrical portion is not particularly limited, and for example, a circular shape, an elliptical shape, a polygonal shape, Various cross-sectional shapes such as those distorted shapes can be adopted, but it is desirable that the first cylindrical portion substantially corresponds to the outer shape of the cross section in the direction perpendicular to the axis of the spring pin. Thereby, it is possible to advantageously secure a contact area between the outer peripheral surface of the spring pin and the inner peripheral surface of the first cylindrical portion. As a result, it is possible to advantageously ensure the frictional force generated between the outer peripheral surface of the spring pin and the inner peripheral surface of the first cylindrical portion, and it is possible to advantageously prevent the axial displacement of the spring pin. It becomes possible.

  Furthermore, in the present invention, the size and shape of the cross section of the first cylindrical portion and the second cylindrical portion in the direction perpendicular to the axis do not need to be constant in the axial direction. The cross-sectional size and shape in the direction perpendicular to the axis may be different on the other end side.

  Further, the spring pin in the present invention is not particularly limited as long as it has a shape that generates a spring action in a direction perpendicular to the axis. For example, the spring pin extends over the entire length in the axial direction in a part of the circumferential direction of the spring pin. The shape in which the notch is formed, the peripheral wall is a cylindrical shape that is continuous in the circumferential direction, the cross-sectional shape in the direction perpendicular to the axis is a polygon that has a roundness at each apex, and A cross-sectional shape in the direction perpendicular to the axis is spiral, and a shape in which at least a part of the peripheral wall overlaps in the direction perpendicular to the axis is adopted. Therefore, when a cut is formed over the entire length in the axial direction in a part of the circumferential direction of the spring pin, the cut does not need to extend straight along the axial direction of the spring pin, For example, it may extend in a direction inclined with respect to the axial direction, or may extend so as to meander.

  Furthermore, in the present invention, the outer shape of the cross section in the direction perpendicular to the axis of the spring pin is not particularly limited as long as it has a shape that causes a spring action in the direction perpendicular to the axis of the spring pin. A substantially oval shape, a substantially polygonal shape, or a distorted shape thereof is employed.

  Furthermore, in the present invention, the thickness dimension of the peripheral wall of the spring pin may be constant in the circumferential direction or may be different. Therefore, in the case of a spring pin in which a cut is formed over the entire length in the axial direction in a part of the circumferential direction, the thickness dimension of the peripheral wall is the largest at the portion facing the cut in the direction perpendicular to the axis. On the other hand, it is desirable that the thickness dimension is gradually reduced from the portion to the cut along the circumferential direction. Thereby, the stress which generate | occur | produces in a 1st cylinder part in the state with which the spring pin was fitted by the 1st cylinder part is made equal to the circumferential direction. As a result, with the spring pin fitted in the first tube portion, the outer peripheral surface of the spring pin can be brought into close contact with the inner peripheral surface of the first tube portion over the entire circumference. It is possible to more advantageously prevent the displacement in the direction of slipping out.

  Furthermore, in the present invention, the spring pin has a shape in which a cut is formed over the entire length in the axial direction in a part of the circumferential direction, and the cross-sectional shape in the direction perpendicular to the axis of the circumferential wall is spiral. When the shape is such that at least a part of the peripheral wall overlaps in the direction perpendicular to the axis, for example, by a method of forming a notch over the entire length of the tube in the axial direction, a method of rounding a plate material, etc. A spring pin is advantageously formed. Further, in the present invention, when the spring pin is a shape in which the peripheral wall is continuous in the circumferential direction and the cross-sectional shape in the direction perpendicular to the axis is a polygon having roundness at each apex, for example, The desired spring pin is advantageously formed by drawing or extruding.

  In the present invention, the material for forming the spring pin is not particularly limited as long as it can advantageously obtain a spring action in a direction perpendicular to the axis. For example, steel, spring steel, and stainless steel for springs are used. Etc. can be adopted.

  Furthermore, in the present invention, the locking state of the plate-like piece with respect to the first cylindrical portion is realized by the plate-like piece being locked to the step formed on the inner peripheral surface of the first cylindrical portion. The plate-like piece may be fitted into the opening hole formed in the first cylinder portion in the direction perpendicular to the axis, and the plate-like piece may be locked to the inner peripheral surface of the opening hole. It may be realized by.

  In the present invention, the operation projection is formed separately from the plate-shaped piece, and when an external force is exerted on the operation projection in the insertion direction of the spring pin, the operation projection is against the plate-shaped piece. On the other hand, when an external force is applied to the operation protrusion in a direction opposite to the spring pin insertion direction, the operation protrusion is removed from the plate-like piece. Thereby, the pressing operation of the operation projection in the spring pin insertion direction is advantageously realized, while the plate-like piece is locked to the opposite side of the spring pin insertion direction with respect to the first cylindrical portion. When the fixed state of the first component member and the second component member is realized and the operation protrusion is no longer necessary, the operation protrusion can be advantageously removed from the plate-shaped piece. The Rukoto. Further, it is possible to advantageously avoid pulling out the spring pin with the operation projection as a clue.

  Therefore, the relationship between the operation protrusion and the plate-like piece as described above is, for example, that a fitting hole is formed in the plate-like piece, while a fitting protrusion is formed in the operation protrusion, and the fitting protrusion is formed. This is advantageously realized by fitting into the fitting hole or by directly fitting the operation projection into the fitting hole formed in the plate-like piece.

  When the plate-like piece and the operation protrusion are formed separately, the plate-like piece and the operation protrusion may be formed of the same material or different materials.

  Furthermore, in the present invention, the spring pin is fitted in the first tube portion, and the leading end portion and the insertion protrusion in the spring pin are in a state where the plate-like piece is accommodated in the internal space of the first tube portion. Assembling of the first component member and the second component member is positioned so that the protruding end of the second cylinder portion is positioned closer to the first cylindrical portion than the opening end surface of the first cylindrical portion in the second cylindrical portion. It is desirable to realize a ready state that allows the release of the state. In this way, in the assembly state release prevention mechanism in the unused state, the first cylindrical part to which the spring pin is fitted is used in order to realize the fixed state of the first component member and the second component member. It becomes possible to prepare a spring pin to be used in the future. As a result, it is possible to advantageously secure a space for arranging spring pins to be used in the future in the unused assembly state release prevention mechanism.

  Note that the above-described preparation state is advantageously realized, for example, by using a static friction force generated between the outer peripheral surface of the spring pin and the inner peripheral surface of the first cylindrical portion.

  Further, as described above, since the opening 22 of the case body 12 is covered with the lid member 14, the control board 16 screwed to the lid member 14 is put into the case body 12 through the opening 22.

  In the present embodiment, as described above, in the state where the opening 22 of the case body 12 is covered with the lid member 14, as shown in FIG. The formed protrusion 56 is adapted to be fitted into an insertion hole 58 formed in the other side wall portion in the width direction of the lid member 14.

  Further, as described above, by sliding and displacing the lid member 14 with respect to the case main body 12, as shown in FIG. 10, the lower accommodating portion 42 in the lid-side cylindrical portion 38 is formed on the main body-side cylindrical portion 28. The upper housing portion 40 of the lid side cylinder portion 38 is positioned in the upper housing portion 34 formed above the lower housing portion 32, while being positioned in the lower housing portion 32 provided above. Yes.

  Accordingly, the lid side cylinder portion 38 and the main body side cylinder portion 28 are positioned on the same central axis in a state where the lid member 14 is assembled to the case main body 12. That is, the lid side cylinder part 38 is provided at a position corresponding to the main body side cylinder part 28 in the lid member 14.

  Then, as described above, the lid side cylinder part 38 and the main body side cylinder part 28 are positioned on the same central axis, so that the internal space 39 of the lid side cylinder part 38 and the internal space 27 of the main body side cylinder part 28 are described later. It will be in the position which permits insertion of the spring pin 60 to perform. That is, in the present embodiment, the lid side cylinder portion 38 and the main body side cylinder portion 28 are positioned on the same central axis in a state where the lid member 14 is assembled to the case main body 12, whereby the lid side cylinder portion. The internal space 39 of 38 and the internal space 27 of the main body side cylinder part 28 are connected.

  In the present embodiment, as described above, with the lid side cylinder portion 38 and the main body side cylinder portion 28 positioned on the same central axis, the lower end surface of the lower accommodation portion 42 in the lid side cylinder portion 38 A gap is formed between the bottom housing portion 32 and the bottom surface 33.

  In the present embodiment, as described above, the lid member 14 is slid and displaced with respect to the case main body 12 so that the top plate 36 moves in parallel with respect to the bottom plate 18. Since the lid member 14 is assembled to the case main body 12, the direction in which the lid side cylinder portion 38 and the main body side cylinder portion 28 are arranged, that is, the lid side cylinder. The direction in which the central axis common to the portion 38 and the main body side cylinder portion 28 extends is the sliding direction of the lid member 14 with respect to the case main body 12, particularly the opening direction as the release direction (the direction from the lower side to the upper side in FIG. 1). Crossed.

  As described above, the spring pin 60 is fitted into the main body side cylinder portion 28 and the lid side cylinder portion 38 that are positioned on the same central axis. Therefore, the spring pin 60 of the present embodiment is formed of steel, spring steel, spring stainless steel, or the like, and as shown in FIG. 11 and FIG. It has a cylindrical shape in which a cut 62 extending while meandering is formed. Such a spring pin 60 is advantageously formed by, for example, rounding a plate material whose both end edges in the longitudinal direction have a sawtooth shape over the entire length in the width direction using an appropriate machine or tool. . Further, the spring pin 60 of the present embodiment is rounded over the entire circumference with respect to the outer corners at both ends in the axial direction. Thereby, the insertion of the spring pin 60 into the main body side cylinder portion 28 and the lid side cylinder portion 38 is advantageously performed from either side of both axial ends.

  In the present embodiment, the assembly pin 64 is attached to such a spring pin 60. The assembly pin 64 is made of a synthetic resin material such as ABS, and as shown in FIGS. 13 to 16, the thickness of the assembly pin 64 is from the central portion of the plate-like piece 66 that is a rectangular flat plate as a whole. An insertion shaft 68 is integrally formed as an insertion protrusion protruding on one side in the direction, and an operation protrusion 59 protruding on the other side in the thickness direction from the central portion of the plate-like piece 66 is provided. Yes.

  Therefore, the operation protrusion 59 of the present embodiment is a fitting protrusion that protrudes from the center portion of the pressing operation plate portion 57 that is slightly smaller than the plate-like piece 66 in plan view to one side in the plate thickness direction. The connecting projection 55 is integrally formed. In particular, in this embodiment, the connection protrusion 55 and the pressing operation plate portion 57 are positioned on the same central axis. The operation protrusion 59 is made of a synthetic resin material such as ABS or a rubber material such as natural rubber.

  The operation protrusion 59 having such a structure is fitted with the connection protrusion 55 in the connection hole 53 as an engagement hole formed in the central portion of the other surface in the plate thickness direction of the plate-like piece 66. As a result, it is provided on the plate-like piece 66 so as to protrude from the central portion of the plate-like piece 66 to the other side in the thickness direction. That is, in this embodiment, the operation protrusion 59 is formed separately from the plate-like piece 66.

  In particular, in the present embodiment, the operation protrusion 59, the plate-like piece 66, and the insertion shaft 68 are positioned on the same central axis line in a state where the operation protrusion 59 is provided on the plate-like piece 66 in this manner. It is like that.

  In the present embodiment, chamfering is applied to the lower corners at both ends in the longitudinal direction of the plate-like piece 66 over the entire length in the width direction of the plate-like piece 66. Thereby, it becomes possible to move advantageously from the upper side opening in the upper side accommodating part 40 of the plate-shaped piece 66 mentioned later to a bottom wall.

  As shown in FIG. 17, the assembly pin 64 having such a structure is inserted into and fixed to the spring pin 60 from the axial end 61 side of the spring pin 60. It is assembled. As is clear from this, in the present embodiment, one end 61 in the axial direction of the spring pin 60 is the end opposite to the preceding end.

  Therefore, in the present embodiment, the insertion pin 68 of the assembly pin 64 is positioned in the spring pin 60 with the assembly pin 64 assembled to the spring pin 60. It is said that. In other words, the protruding end 65 of the insertion shaft 68 inserted into the spring pin 60 from the opening of the axial one end 61 does not protrude outward in the axial direction from the opening of the axial other end 63 of the spring pin 60. It has become.

  Further, in the present embodiment, as described above, the assembly pin 64 (the connecting projection 55 and the pressing projection 55 on the insertion shaft 68, the plate-like piece 66, and the operation projection 59 is pressed in a state where the assembly pin 64 is assembled to the spring pin 60. The plate part 57) is positioned on the central axis of the spring pin 60. That is, in this embodiment, the spring pin 60, the insertion shaft 68, the plate-like piece 66, the connecting projection 55, and the pressing operation plate portion 57 are positioned on the same central axis. As a result, when an external force is applied to the operation protrusion 59 in the insertion direction of the spring pin 60, the connection protrusion 55 of the operation protrusion 59 is fitted into the connection hole 53 formed in the plate-like piece 66, that is, While the state in which the operation protrusion 59 is assembled to the plate-like piece 66 is maintained, an external force is applied to the operation protrusion 59 in the pulling direction, that is, the direction opposite to the insertion direction of the spring pin 60. When extended, the operation protrusion 59 is removed from the plate-like piece 66 by pulling out the connection protrusion 55 in the operation protrusion 59 from the connection hole 53 formed in the plate-like piece 66.

  As described above, the spring pin 60 to which the assembly pin 64 is assembled is, as shown in FIG. 18, from the other axial end 63 side to which the assembly pin 64 is not attached to the lid side cylinder portion 38. To be inserted. That is, in the present embodiment, the other axial end 63 of the spring pin 60 is the leading end. 18 to 20, the spring pin 60 and the assembly pin 64 assembled thereto are not shown in cross-sectional views.

  In this state, in the state where the spring pin 60 is fitted in the lid side cylinder portion 38, one end 61 in the axial direction of the spring pin 60, that is, the end where the assembly pin 64 is assembled in the spring pin 60 is the lid side. It is positioned in the upper housing part 40 in the cylinder part 38. Further, the plate-like piece 66 in the assembly pin 64 assembled to the axial one end 61 side of the spring pin 60 is accommodated in the upper accommodation part 40 in the lid side cylinder part 38.

  In particular, in the present embodiment, the upper surface 67 of the plate-like piece 66, that is, the surface on which the operation protrusion 59 is provided on the plate-like piece 66 in a state where the plate-like piece 66 is accommodated in the upper accommodation portion 40. However, the upper end surface 69 of the upper housing part 40 in the lid side cylinder part 38, that is, the opening end face on the opposite side to the insertion direction of the spring pin 60 in the lid side cylinder part 38 is positioned at substantially the same height. As a result, the operation protrusion 59 is projected from the upper end surface 69 of the upper housing portion 40 in the lid side cylinder portion 38, that is, from the opening end surface located on the side opposite to the main body side cylinder portion 28 in the lid side cylinder portion 38. It is.

  In the present embodiment, as described above, the other end 63 in the axial direction of the spring pin 60 is connected to the lower housing portion 42 in the lid-side cylinder portion 38 in a state where the spring pin 60 is fitted in the lid-side cylinder portion 38. It is located inside. That is, the other end 63 in the axial direction of the spring pin 60 and the protruding end 65 of the insertion shaft 68 inserted and fixed to the spring pin 60 are the lower housing portion serving as the opening end surface of the main body side tubular portion 28 on the lid side tubular portion 38 side. It is positioned closer to the lid side cylinder portion 38 than the bottom surface 33 of 32.

  In the present embodiment, as described above, the spring pin 60 is fitted into the lid-side cylinder portion 38, so that the spring pin 60 is inserted into the lower accommodation portion 42 of the spring pin 60. The force of tightening will act. As a result, a force (restoring force) for the spring pin 60 to return to the original shape acts on the lower accommodating portion 42. As a result, the outer peripheral surface of the portion of the spring pin 60 that is fitted into the lower housing portion 42 is pressed against the inner peripheral surface of the lower housing portion 42, and the spring pin 60 is fitted into the lower housing portion 42. A frictional force is generated between the outer peripheral surface of the inserted portion and the inner peripheral surface of the lower accommodating portion 42 in a direction that prevents the axial displacement of the spring pin 60.

  Accordingly, in the present embodiment, the spring pin 60 is based on the static frictional force generated between the outer peripheral surface of the portion of the spring pin 60 fitted in the lower storage portion 42 and the inner peripheral surface of the lower storage portion 42. The pin 60 is fitted and fixed to the lower housing part 42 in the lid side cylinder part 38, and as a result, the accommodation state of the spring pin 60 in the lid side cylinder part 38 as described above is realized. ing.

  That is, in the present embodiment, as described above, the static frictional force generated between the outer peripheral surface of the portion of the spring pin 60 fitted in the lower housing portion 42 and the inner peripheral surface of the lower housing portion 42 is used as described above. The spring pin 60 is fitted into the lid side cylinder portion 38, the plate-like piece 66 is accommodated in the internal space 39 of the lid side cylinder portion 38, and the other axial end 63 of the spring pin 60 is the lid side cylinder. The state positioned in the internal space 39 of the part 38 is a preparation state.

  Then, as described above, the spring pin 60 is further fitted against the frictional force by pressing the pressing operation plate portion 57 in the operation projection 59 from the state where the spring pin 60 is fitted in the lower housing portion 42. Put in. At that time, the operation projection 59 is maintained in a state where the connection projection 55 is fitted into the connection hole 53 formed in the plate-like piece 66, and the operation projection 59 and the plate-like piece 66 are integrated to form the spring pin 60. It moves in the insertion direction. Accordingly, as shown in FIG. 19, the other axial end 63 of the spring pin 60 reaches the inner space 27 of the main body side cylinder portion 28, and the spring pin 60 is connected to the lid side cylinder portion 38 and the main body side. In this state, the one end 61 in the axial direction of the spring pin 60 is positioned in the lid side cylinder portion 38. As a result, sliding displacement of the lid member 14 relative to the case body 12 in the opening direction is prevented by the spring pin 60 inserted across the lid side cylinder part 38 and the body side cylinder part 28, A fixed state in which the lid member 14 is fixed is realized.

  Therefore, in the present embodiment, as described above, the spring pin 60 is inserted into the lower accommodating portion 42 of the spring pin 60 in a state where the spring pin 60 is inserted across the lid side cylindrical portion 38 and the main body side cylindrical portion 28. A force for tightening the spring pin 60 in a direction perpendicular to the axis acts only on the portion that is present. That is, in the present embodiment, the frictional force that prevents the axial displacement of the spring pin 60 is exerted only on the portion of the spring pin 60 that is fitted in the lower housing portion 42, and as a result, The spring pin 60 is fitted and fixed only to the lid side cylinder part 38 (lower accommodation part 42).

  Further, in this embodiment, when the spring pin 60 is further fitted by pressing the operation protrusion 59 (pressing operation plate portion 57) from the state shown in FIG. 18, the spring pin 60 is fixed to the spring pin 60. Both ends of the plate-like piece 66 in the assembly pin 64 in the longitudinal direction slide with respect to a pair of opposing wall portions 70 and 70 that are opposed to each other in the longitudinal direction of the upper housing portion 40 (the left-right direction in FIGS. 7 and 18). It is supposed to be squeezed.

  Therefore, in the present embodiment, the distance between the opposed surfaces of the pair of opposed wall portions 70 is gradually shortened from the upper opening of the upper accommodating portion 40 toward the bottom wall. As a result, the longitudinal ends of the plate-like piece 66 of the assembly pin 64 fixed to the spring pin 60 gradually warp toward the upper opening side of the upper accommodating portion 40 as it goes to the bottom wall side of the upper accommodating portion 40. It is supposed to be.

  In the present embodiment, when the plate-like piece 66 reaches the bottom wall of the upper accommodating portion 40, each of the both longitudinal ends of the plate-like piece 66 is warped from the upper opening side of the upper accommodating portion 40. In addition to returning to this state, it enters the opening hole 72 formed in the vicinity of the bottom wall of each opposing wall portion 70. As a result, both end portions in the longitudinal direction of the plate-like piece 66 are surfaces located on the opposite side of the inner peripheral surface 74 of the opening hole 72 formed in each opposing wall portion 70 from the insertion direction of the spring pin 60. By being locked, the displacement of the assembling pin 64 toward the upper opening side of the upper housing portion 40, and further, the displacement of the spring pin 60 in the axial direction upward (opposite to the insertion direction which is the removal direction). (Displacement in the direction of) is prevented.

  In this way, the plate-like piece 66 abuts against the bottom wall of the upper accommodating portion 40 in a state where both ends in the longitudinal direction of the plate-like piece 66 are locked to the inner peripheral surface 74 of the opening hole 72. It is touched. Thereby, the displacement to the lower side accommodating part 42 side of the assembly | attachment pin 64 is controlled.

  Therefore, in the present embodiment, as described above, the both ends of the plate-like piece 66 in the longitudinal direction are engaged with the inner peripheral surface 74 of the opening hole 72, so that the pressing operation plate portion 57 of the operation protrusion 59 is The upper surface is positioned at substantially the same height as the upper end surface 69 of the lid-side cylinder portion 38.

  Then, from this state, using the pressing operation plate portion 57 as a clue, the connection protrusion 55 in the operation protrusion 59 is pulled out from the connection hole 53 formed in the plate-shaped piece 66, and the operation protrusion 59 is removed from the plate-shaped piece 66. As shown in FIG. 20, only the plate-like piece 66 and the insertion shaft 68 in the assembly pin 64, that is, only the portion formed integrally with the assembly pin 64 is accommodated in the lid-side cylinder portion 38. Will be.

  In the present embodiment, the spring pin 60 is fitted and fixed to the lid side cylinder portion 38, and the upper surface 67 of the plate-like piece 66 is positioned at the same height as the upper end surface 69 of the lid side cylinder portion 38. Below, as shown in FIG. 21, a gap is formed between the widthwise ends of the plate-like piece 66 and the upper accommodating portion 40.

  In particular, in the present embodiment, although not necessarily clear on the drawing, the upper surface 67 of the plate-like piece 66 is positioned at the same height as the upper end surface 69 of the lid-side cylinder portion 38 (upper accommodation portion 40). A gap is formed between the both ends in the width direction of the plate-like piece 66 and the upper accommodating portion 40 until both ends in the longitudinal direction of the plate-like piece 66 enter the opening holes 72, 72. . Thus, only the both longitudinal ends of the plate-like piece 66 are open on the upper side of the upper accommodating portion 40 until the spring pin 60 is inserted across the lid side cylindrical portion 38 and the main body side cylindrical portion 28. It is designed to warp to the side. As a result, the resistance from the state where the spring pin 60 is fitted only to the lid side cylinder part 38 to the state where the spring pin 60 is inserted across the lid side cylinder part 38 and the main body side cylinder part 28 is reduced. It becomes possible to do.

  As is clear from the above description, in this embodiment, in this embodiment, the main body side cylinder portion 28 formed integrally with the case main body 12 and the lid side cylinder portion formed integrally with the lid member 14. The lock mechanism 11 is configured to include the spring pin 60, the plate-like piece 66, and the insertion shaft 68 inserted across the main body side cylinder portion 28 and the lid side cylinder portion 38.

  Further, although not clearly shown in the drawing, in the present embodiment, only one of the lock mechanisms 11 of the lock mechanism group 76 configured by gathering the four lock mechanisms 11 is shown in FIG. As shown, the spring pin 60 is inserted across the main body side cylinder portion 28 and the lid side cylinder portion 38, that is, the state where the assembled state release preventing function is exhibited, In all of the lock mechanisms 11, as shown in FIG. 18, a state in which the spring pin 60 is fitted only in the lid-side cylinder portion 38, that is, a ready state in which the assembled state release prevention function is not exhibited. Has been.

  Of course, in the lock mechanism 11 in a state where the assembled state release preventing function is exhibited, as shown in FIG. 19, it is possible to keep the operation projection 59 attached.

  In the lock mechanism 11 having such a structure, in a state where the lid member 14 is assembled to the case body 12, the lock mechanism 11 is on a central axis extending in a direction orthogonal to the sliding displacement direction of the lid member 14 with respect to the case body 12. A spring pin 60 that is inserted across the positioned lid-side cylinder part 38 (lower accommodation part 42) and the main body-side cylinder part 28 is fitted and fixed to the lower accommodation part 42 in the lid-side cylinder part 38. Therefore, the sliding displacement of the lid member 14 with respect to the case body 12 in the opening direction is prevented by the spring pin 60. As a result, the fixed state of the case body 12 and the lid member 14, Maintenance of the assembled state is realized.

  In this case, the spring pin 60 inserted across the lid side cylinder portion 38 and the main body side cylinder portion 28 has a cylindrical shape divided at a part in the circumferential direction, and generates a spring action in a direction perpendicular to the axis. Therefore, the spring exerted by the lower housing part 42 (lid side cylinder part 38) in a state where the spring pin 60 is inserted across the lid side cylinder part 38 and the main body side cylinder part 28. A reaction force of the force for fastening the pin 60 is applied to the lower accommodating portion 42 (the lid-side cylinder portion 38).

  Thereby, between the outer peripheral surface of the part inserted in the lower side accommodating part 42 (lid side cylinder part 38) in the spring pin 60, and the inner peripheral surface of the lower side accommodating part 42 (lid side cylinder part 38). A frictional force acting in a direction that prevents the axial displacement of the spring pin 60 is generated.

  Therefore, in the lock mechanism 11 having the above-described structure, the main body side cylinder portion 28 and the lid side cylinder portion 38 have dimensional errors during molding, or are caused by changes in the ambient temperature of the board case 10 for gaming machines. Even if the main body side cylinder portion 28 and the lid side cylinder portion 38 are deformed, it is possible to advantageously realize the stable fixing state of the case main body 12 and the lid member 14 and the maintenance of the assembled state. As a result, sliding displacement of the lid member 14 with respect to the case body 12 in the opening direction, that is, release of the assembled state of the case body 12 and the lid member 14 can be advantageously prevented.

  Further, in the state where the spring pin 60 is inserted across the lower housing part 42 (lid side cylinder part 38) and the main body side cylinder part 28, both ends in the longitudinal direction of the plate-like piece 66 are opened holes 72, 72, when the spring pin 60 is about to be displaced in the axial direction, that is, in the withdrawal direction which is the direction opposite to the insertion direction, both ends in the longitudinal direction of the plate-like piece 66 Each of these is locked to the surface on the opposite side to the insertion direction of the spring pin 60 with respect to the inner peripheral surface 74 of the opening hole 72. Thus, for example, even if an attempt is made to push back the spring pin 60 in the direction opposite to the insertion direction by making a hole in the bottom wall of the main body side cylinder portion 28, each end portion in the longitudinal direction of the plate-like piece 66 Is locked to the inner peripheral surface 74 of the opening hole 72, so that displacement in the direction opposite to the insertion direction of the spring pin 60 can be prevented. As a result, it is possible to more advantageously realize the stable fixing state of the case main body 12 and the lid member 14, and thus the maintenance of the assembled state, and release the assembled state of the case main body 12 and the lid member 14. It becomes possible to prevent more advantageously.

  Further, since the insertion shaft 68 is formed to project from the central portion of the plate-like piece 66, the plate-like shape in the process until the spring pin 60 is inserted across the lid-side cylinder portion 38 and the main body-side cylinder portion 28. Warpage of both ends in the longitudinal direction of the piece 66 can be advantageously realized.

  Furthermore, since the operation projection 59 is projected from the plate-like piece 66 of the assembly pin 64 fixed to the spring pin 60, the operation projection 59 is pressed by the operation of inserting the spring pin 60. This can be advantageously performed.

  Therefore, in the present embodiment, the pressing operation plate portion 57 that is touched by the operator's finger or the like when pressing the operation protrusion 59 is more than the connection protrusion 55 that connects the operation protrusion 59 and the plate-like piece 66 in plan view. Therefore, it is possible to facilitate the pressing operation of the operation protrusion 59.

  In the present embodiment, the spring pin 60, the insertion shaft 68, the plate-like piece 66, the connecting projection 55, and the pressing operation plate portion 57 are positioned on the same central axis. The force to be transmitted is efficiently transmitted in the direction of the central axis of the spring pin 60, and the insertion operation of the spring pin 60 can be realized more advantageously.

  Furthermore, in the present embodiment, since the operation protrusion 59 protrudes from the center portion of the plate-like piece 66 to the other side in the plate thickness direction, the spring pin 60 is attached to the lid side cylinder portion 38 and the main body side cylinder portion 28. Warpage of both ends in the longitudinal direction of the plate-like piece 66 in the process until it is inserted across the board can be advantageously realized.

  In the present embodiment, since the operation protrusion 59 can be detached from the plate-like piece 66, when the operation protrusion 59 is used, that is, each of the both ends in the longitudinal direction of the plate-like piece 66 is opened. When fitted in the holes 72, 72, the operation projection 59 is removed from the plate-like piece 66, so that only the integrally formed portion (the insertion shaft 68 and the plate-like piece 66) of the assembly pin 64 is inside the lid-side cylinder portion 38. It is possible to place it in the storage position. As a result, it is possible to advantageously avoid the spring pin 60 being pulled out with the operation projection 59 as a clue.

  Furthermore, in the present embodiment, since the main body side cylindrical portion 28 has a bottomed cylindrical shape, the spring pin 60 is provided with the main body side cylindrical portion 28 unless a hole is made in the bottom wall of the main body side cylindrical portion 28. In addition, a frictional force acts between the spring pin 60 and the lower housing portion 42 of the lid side cylinder portion 38 in a direction opposite to the pulling direction of the spring pin 60. As a result, it is possible to advantageously prevent the spring pin 60 from being pulled out. As a result, the case body 12 and the lid member 14 are fixed, and further maintained in the assembled state. Therefore, it is possible to more advantageously prevent release of the assembled state of the case main body 12 and the lid member 14.

  Further, in the present embodiment, maintaining the state where the spring pin 60 is fitted only in the lid-side cylinder portion 38 means that the outer peripheral surface and the lower portion of the portion of the spring pin 60 fitted in the lower housing portion 42 are maintained. Since it is realized based on the static friction force generated between the inner peripheral surface of the side housing portion 42, the function of preventing the assembly state release of the case body 12 and the lid member 14 is not exhibited. A spring pin 60 to be used in the lock mechanism 11 in which the function of preventing the assembled state of the case main body 12 and the lid member 14 is not exhibited by skillfully using the lid side cylinder portion 38 constituting the lock mechanism 11. That is, the spring pin 60 to be inserted between the main body side cylinder portion 28 and the lid side cylinder portion 38 can be advantageously disposed. As a result, it is possible to advantageously secure an arrangement space for the spring pin 60 to be used in the future in the lock mechanism 11 in which the function of preventing the assembly state release of the case body 12 and the lid member 14 is not exhibited.

  Further, in the present embodiment, since the spring pin 60 is fitted and fixed only to the lower housing part 42 (lid side cylinder part 38), the lid side cylinder part 3 is attached to the peripheral wall of the lid member 14. The spring pins 60 can be easily extracted from the main body side cylinder portion 28 simply by separating the lid side cylinder portion 38 from the lid member 14 by cutting the attachment pieces 44, 44 connected to 37 with a nipper or the like. It becomes possible. As a result, it is possible to quickly perform the opening operation of the gaming machine substrate case 10 while leaving a trace of the lock mechanism 11 being destroyed.

  As mentioned above, although one Embodiment of this invention was explained in full detail, this is an illustration to the last, Comprising: This invention is not limited at all by the specific description in this Embodiment.

  For example, it is not always necessary to chamfer the corner of the spring pin 60 on the outer side in the axial direction in the embodiment. Further, the lower housing part 32 and the upper housing part 34 in the embodiment are not necessarily required.

  Further, the portion of the spring pin that is divided in the circumferential direction does not need to meander as in the above-described embodiment, and may extend straight. Furthermore, the spring pin may have a structure in which a plate material is wound more than once.

  Furthermore, an insertion member made of a material having a hardness lower than that of the spring pin forming material may be inserted into and fixed to the cylindrical spring pin divided in the circumferential direction. As a result, it is possible to advantageously ensure the separation distance of the portion divided in the circumferential direction in the spring pin, and as a result, it is possible to advantageously obtain the spring action in the direction perpendicular to the axis of the spring pin. For example, hard rubber, silicone, ceramics, urethane, or the like is employed as a material for forming the insertion member.

  Further, the spring pin 60 may be fitted and fixed to both the lid side cylinder part 38 and the main body side cylinder part 28.

  Moreover, in the said embodiment, the internal diameter dimension of the lower side accommodating part 42 may be made small gradually as it goes from an axial upper end to an axial lower end. Thereby, it becomes possible to implement | achieve the insertion operation | work of the spring pin 60 advantageously.

  Further, as the shape viewed from the direction orthogonal to the plate surface of the plate-like piece, any of a circle, an ellipse, a polygon and the like can be adopted.

  Furthermore, the operation protrusion may be formed integrally with the plate-shaped piece. In this case, when the operation protrusion is integrally formed with the plate-like piece, it is desirable to separate the operation protrusion from the plate-like piece when the operation protrusion is used up. Accordingly, it is possible to advantageously avoid pulling out the spring pin with the operation projection as a clue. Specifically, for example, when the operation protrusion is pressed, a weak portion having a strength that does not cause deformation such as crushing is provided in a connection portion with the plate-like piece in the operation protrusion, and the weak portion is provided. It is conceivable to separate the operation projection from the plate-shaped piece by twisting it off.

  Further, in the above-described embodiment, the upper surface of the pressing operation plate portion 57 of the operation projection 59 is in the state of the lid-side cylinder portion 38 in a state where both longitudinal ends of the plate-like piece 66 are fitted into the opening holes 72, 72. It may be positioned above the upper end surface 69. As a result, it is possible to more advantageously realize the operation of removing the operation protrusion 59 using the pressing operation plate portion 57 as a clue.

  Furthermore, the preparation state may be realized by using a static frictional force generated between the outer peripheral surface of the plate-like piece and the inner peripheral surface of the first cylindrical portion in which the plate-like piece is accommodated. good.

  Furthermore, the control board 16 does not need to be screwed to the lid member 14, and by inserting a protrusion provided on the lid member 14 into a hole formed at an appropriate position of the control board 16, It may only be positioned with respect to the lid member 14.

  Furthermore, in the above-described embodiment, the lock mechanism employed in the gaming machine substrate case from the viewpoint of preventing fraud has been described, but the present invention is merely a second configuration relative to the first component. Of course, it is also possible to employ as a means for assembling and fixing the members.

  In addition, although not enumerated one by one, the present invention can be implemented in a mode with various changes, modifications, improvements, and the like based on the knowledge of those skilled in the art. It goes without saying that all are included in the scope of the present invention without departing from the spirit of the present invention.
