Description

  The present invention relates to a fixture for fixing members and a board case of a gaming machine using the fixture.

Conventionally, a pin or the like has been used as a fixing tool for fixing a member, and various shapes of the pin are provided. For example, in a board case of a gaming machine, a caulking pin is used to fix the main body and cover of the board case (for example, Patent Document 1). These caulking pins have an arrowhead shape whose tip functions as a retainer, and when they are pushed into the hole that is the fixing partner, they engage with the opening edge of the hole with the arrowhead open and cannot be removed. .
JP 2005-13545 A

However, the above-described conventional fixing device such as a caulking pin has only one shaft body that can be inserted by a single pressing operation. In addition, the insertion direction of the pin is limited to the pressed direction.
Accordingly, an object of the invention described in each claim is to provide a fixture capable of inserting a plurality of shaft bodies by a single pressing operation, and a board case of a gaming machine using the fixture. Also, in the insertion direction of the shaft body, there is provided a fixture that can insert the shaft body in a direction other than the pressed direction, and a board case for a gaming machine using the fixture. The task is to do.

The invention described in each claim is made to solve the above-described problems. Hereinafter, the features and operations of the invention described in each claim will be described using the embodiments of the invention shown in the drawings.
In addition, a code | symbol shows the code | symbol used in embodiment of this invention, and does not limit the technical scope of this invention.
(Claim 1)
The invention according to claim 1 is characterized by the following.
That is, the fixture 81 according to claim 1 is pushed in a direction orthogonal to a direction in which the first shaft main body 82 is pushed in, and a first shaft main body 82 that is pushed into the first fixing portion 61 and fixed. A second shaft main body 91 fixed to the two fixed portions 62, and when the first shaft main body 82 is pushed into the first fixed portion 61, the force to be pushed in a direction orthogonal to the force to be pushed in. A force direction conversion mechanism for converting the force into a force and transmitting it to the second shaft main body 91 is provided.

  Here, the “first shaft main body” is intended to be pushed into the first fixing portion and fixed. As this 1st axis | shaft main body, the pin etc. which are provided in order to latch a some member correspond, for example. For example, when there are a plurality of members that are locked by pins, the “first fixing portion” can be provided as a through-hole that is continuous with the plurality of members. That is, for example, when a through-hole is provided as the first fixing portion, a plurality of members are fixed by pressing and fixing the pin that is the first shaft body into the through-hole. The first shaft main body is not limited to fixing a plurality of members, but may be simply inserted into a hole to fix the first shaft main body itself. Further, the first fixing portion does not need to be a through hole, and may be provided as a recess or a slit.

  Similarly, the “second shaft main body” is intended to be pushed into and fixed to the second fixing portion. As this 2nd axis | shaft main body, the pin etc. which are provided in order to latch a some member correspond, for example. For example, when there are a plurality of members locked by pins, the “second fixing portion” can be provided as a through-hole or the like provided continuously to the plurality of members. That is, for example, when a through-hole is provided as the second fixing portion, a plurality of members are fixed by pressing and fixing the pin that is the second shaft body into the through-hole. The second shaft main body is not limited to fixing a plurality of members, but may be simply inserted into a hole to fix the second shaft main body itself. Further, the second fixing portion does not need to be a through hole, and may be provided as a recess or a slit.

  The second shaft main body is pushed and fixed in a direction orthogonal to the direction in which the first shaft main body is pushed. That is, the first shaft main body and the second shaft main body are pressed and fixed to the first fixing portion and the second fixing portion, respectively, in a state orthogonal to each other. The state in which the first shaft body and the second shaft body are orthogonal to each other (hereinafter referred to as “axis orthogonal state”) is not necessarily a state in which the first shaft body and the second shaft body are fixed. By setting the first shaft main body and the second shaft main body to be fixed, the first shaft main body and the second shaft main body can be more easily pushed and fixed. As a state in which the first shaft main body and the second shaft main body are fixed, for example, by inserting the second shaft main body into the first shaft main body, an axial orthogonal state may be taken. By inserting the first shaft main body into the second shaft main body, an axial orthogonal state may be obtained. Moreover, you may make it take an axial orthogonal state by providing the member which connects a 1st axis | shaft main body and a 2nd axis | shaft main body. Furthermore, by fixing the first shaft main body to a predetermined member other than the fixture, for example, a member having the first fixing portion, an axis orthogonal state can be taken when the second shaft main body is disposed at a predetermined position. You may do it. Further, by fixing the second shaft main body to a predetermined member other than the fixture, for example, a member having the second fixing portion, it is possible to take an axis orthogonal state when the first shaft main body is disposed at a predetermined position. Anyway.

  The “force direction converting mechanism” is for converting the pushed force into a force perpendicular to the pushed force when the first shaft body is pushed into the first fixed portion in the above-described axis orthogonal state. Is. Further, by transmitting the converted force to the second shaft main body, an urging force is applied to the second shaft main body, and the second shaft main body is pushed into and fixed to the second fixing portion. That is, by providing this force direction conversion mechanism, when the first shaft main body is pressed so as to be pushed into the first fixed portion, the pressing force is not only the pressed direction but also the pressed direction. Transmission is also possible in a direction perpendicular to this, and this makes it possible to apply a biasing force to the second shaft body. And as a result of urging | biasing force being given to the 2nd axis | shaft main body, the 2nd axis | shaft main body is formed so that it may be pushed in and fixed to the 2nd fixing | fixed part.

In addition, although the fixing tool described in this claim has the first shaft main body and the second shaft main body, it may have another shaft main body other than the first shaft main body and the second shaft main body. I do not care. That is, the number of shafts that are pushed into and fixed to the fixing partner is not limited to two, and may be three or more.
(Operation of the Invention of Claim 1)
In such a fixture, when the first shaft main body is pushed into the first fixing portion and fixed, the force direction changing mechanism applies a biasing force to the second shaft main body, so that the second shaft main body is simultaneously It is pushed into the second fixing part and fixed.

(Claim 2)
The invention described in claim 2 is characterized by the following in addition to the features of the invention described in claim 1 described above.
That is, the force direction conversion mechanism is composed of at least a first inclined surface 88 provided on the first shaft main body 82 and a second sliding contact portion 95 provided on the second shaft main body 91, The first inclined surface 88 is inclined with respect to the direction in which the first shaft main body 82 is pushed, and the first inclined surface 88 of the second shaft main body 91 is moved when the first shaft main body 82 is pushed into the first fixing portion 61. When the force to be pushed by contact with the two sliding contact portions 95 is formed to be transmitted to the second shaft main body 91, and the first shaft main body 82 is pushed into the first fixing portion 61, By providing a movement restricting member 77 in the vicinity of the second fixed portion 62 that prevents the movement of the second shaft main body 91 in the pushing direction, the second shaft main body 91 in contact with the movement restricting member 77 is inclined in the first direction. The surface 88 is pressed and slid, and the urging force in the direction of the second fixing portion 62 is applied to the second shaft main body 91. And wherein the Erareru.

Here, the “first inclined surface” is a surface provided on the first shaft main body, and is inclined at a predetermined angle with respect to the direction in which the first shaft main body is pushed, that is, the axial direction of the first shaft main body. Is.
The “second sliding contact portion” is a portion that is provided on the second shaft main body and comes into contact with the first inclined surface when the first shaft main body is pushed into the first fixing portion.
The first inclined surface and the second sliding contact portion come into contact with each other so that when the first shaft body is pushed into the first fixed portion, the pushing force can be transmitted to the second shaft body. . That is, when the first shaft main body is pushed into the first fixing portion, the first inclined surface presses the second sliding contact portion, and thereby the second shaft main body is pushed in the pushing direction. Yes.

The “movement restricting member” is for restricting the second shaft body from moving more than a certain amount in the pushed direction when the first shaft body is pushed into the first fixing portion. For example, it is conceivable to provide a protrusion or the like on a fixing partner that fixes the first shaft body or the second shaft body.
And the said force direction conversion mechanism is comprised at least from the above-mentioned 1st inclined surface and 2nd sliding contact part. That is, when the first shaft main body is pushed into the first fixed portion, a movement restricting member that prevents the movement of the second shaft main body in the pushing direction is provided in the vicinity of the second fixed portion. Accordingly, the second shaft main body that is in contact with the movement restricting member is pressed and slid by the first inclined surface, and the second shaft main body is configured to be given a biasing force toward the second fixed portion. . More specifically, when the first shaft body is pushed into the first fixed portion, the first inclined surface presses the second sliding contact portion of the second shaft body, and the second shaft is pushed in the direction in which the first shaft body is pushed. Try to move the body. However, since the movement restricting member is provided, the second shaft main body in contact with the movement restricting member cannot move further in the direction in which the first shaft main body is pushed. And since the 1st inclined surface inclines, the 2nd sliding contact part of the 2nd axis | shaft main body slides along the 1st inclined surface, and tries to escape the force pushed in. Thereby, an urging force is applied to the second shaft main body. And the 2nd axis | shaft main body to which the urging | biasing force was given is pushed and fixed to the 2nd fixing | fixed part.

  In addition, as a specific example of the place where the first inclined surface is provided, for example, it is conceivable to provide a notch for inserting the second shaft main body into the first shaft main body. In other words, the inner surface of this notch and the surface on the side opposite to the end pushed into the first fixing portion can be the first inclined surface. In this case, as the second sliding contact portion, for example, an end portion on the side inserted into the notch of the first shaft main body can be used. More specifically, for example, the end surface of the second shaft main body on the side inserted into the notch is formed to be parallel to the first inclined surface, and this end surface can be used as the second sliding contact portion. Accordingly, when the first shaft main body is pushed into the first fixed portion and the first inclined surface presses the second sliding contact portion, the second sliding contact portion can slide on the first inclined surface. Thus, the pushed force is converted into a force in a direction orthogonal to the pushed force and can be transmitted to the second shaft main body.

The first inclined surface is not limited to the above. For example, a protrusion may be provided on the side surface of the first shaft body, and one surface of the protrusion may be the first inclined surface. That is, a surface facing the direction in which the first shaft main body is pushed into the protruding portion may be provided, and this surface may be the first inclined surface. In this case, the 1st inclined surface provided in this protrusion part will slidably contact with the 2nd sliding contact part of a 2nd axis | shaft main body.
Further, the second sliding contact portion is not limited to the above, and the end surface may be projected in a hemispherical shape, and the portion other than the end portion may be the second sliding contact portion. However, when the second sliding contact portion is formed as a flat surface as described above, the magnitude of the urging force in the direction of the second fixed portion applied to the second shaft body is grasped as compared with the case where the second sliding contact portion is formed as a curved surface. There is an advantage that it can be designed easily. In other words, when formed in a plane, the distance to which the second shaft main body is pushed is determined in direct proportion to the distance to which the first shaft main body is pushed. Therefore, the relationship of the movement distance between the first shaft main body and the second shaft main body is determined. Easy to calculate. Specifically, for example, the inclination of the first inclined surface is provided so as to be 30 degrees with respect to the direction in which the first shaft main body is pushed in and 60 degrees with respect to the direction in which the second shaft main body is pushed in. In other words, in other words, the inclination of the second sliding contact portion is provided to be 30 degrees with respect to the direction in which the first shaft main body is pushed in and 60 degrees with respect to the direction in which the second shaft main body is pushed in. When the first shaft main body is pushed in while the second shaft main body is in contact with the movement restricting member, if the distance by which the first shaft main body is pushed is 2, the second shaft main body is pushed by a distance of 1. It becomes.

The first inclined surface does not necessarily need to be a flat surface. For example, in order to make the first inclined surface and the second sliding contact portion slide more smoothly, a guide groove is provided on the first inclined surface, and the second sliding contact portion can slide along the guide groove. good.
(Operation of the Invention of Claim 2)
In such a fixture, when the first shaft main body is pushed into the first fixing portion in the axial orthogonal state, when the second shaft main body comes into contact with the movement restricting member, a biasing force is applied to the second shaft main body. Given. Thereby, when the first shaft main body is pushed into the first fixing portion and fixed, the second shaft main body is simultaneously pushed into the second fixing portion and fixed.

(Claim 3)
The invention described in claim 3 has the following characteristics in addition to the features of the invention described in claim 1 described above.
That is, the force direction conversion mechanism is at least configured by at least a first sliding contact portion 88 provided on the first shaft main body 82 and a second inclined surface 95 provided on the second shaft main body 91. The first slidable contact portion 88 applies the force to be pushed by contacting the second inclined surface 95 of the second shaft main body 91 when the first shaft main body 82 is pushed into the first fixing portion 61. A second inclined surface 95 is formed so as to be able to transmit to the second shaft body 91, and the second inclined surface 95 is in a direction in which the first shaft body 82 is pushed when the first shaft body 82 is pushed into the first fixing portion 61. A movement restricting member 77 that is formed so as to be inclined and prevents the movement of the second shaft main body 91 in the pushing direction when the first shaft main body 82 is pushed into the first fixing portion 61. Is provided in the vicinity of the second fixing portion 62, so that the second abutting against the movement restricting member 77 is provided. The shaft main body 91 is slid by being pressed by the first sliding contact portion 88, and a biasing force in the direction of the second fixing portion 62 is given to the second shaft main body 91.

Here, the “second inclined surface” is a surface provided on the second shaft main body, and is inclined at a predetermined angle with respect to the direction in which the first shaft main body is pushed, that is, the axial direction of the first shaft main body. Is.
Further, the “first sliding contact portion” is a portion that is provided on the first shaft main body and comes into contact with the second inclined surface when the first shaft main body is pushed into the first fixing portion.
The second inclined surface and the first sliding contact portion come into contact with each other so that when the first shaft body is pushed into the first fixed portion, the pushing force can be transmitted to the second shaft body. . That is, when the first shaft main body is pushed into the first fixed portion, the first sliding contact portion presses the second inclined surface, so that the second shaft main body is pushed in the pushing direction. Yes.

The “movement restricting member” is for restricting the second shaft body from moving more than a certain amount in the pushed direction when the first shaft body is pushed into the first fixing portion. For example, it is conceivable to provide a protrusion or the like on a fixing partner that fixes the first shaft body or the second shaft body.
And the said force direction conversion mechanism is comprised at least from the above-mentioned 2nd inclined surface and 1st sliding contact part. That is, when the first shaft main body is pushed into the first fixed portion, a movement restricting member that prevents the movement of the second shaft main body in the pushing direction is provided in the vicinity of the second fixed portion. As a result, the second shaft main body in contact with the movement restricting member is pressed and slid by the first sliding contact portion, and the second shaft main body is formed so as to be given a biasing force toward the second fixed portion. Yes. More specifically, when the first shaft main body is pushed into the first fixed portion, the first sliding contact portion presses the second inclined surface of the second shaft main body, and the second shaft is pushed in the direction in which the first shaft main body is pushed. Try to move the body. However, since the movement restricting member is provided, the second shaft main body in contact with the movement restricting member cannot move further in the direction in which the first shaft main body is pushed. And since the 2nd inclined surface inclines, a 2nd inclined surface slides so that the pressing force of the 1st sliding contact part of a 1st axis | shaft main body may be released. Thereby, an urging force is applied to the second shaft main body. And the 2nd axis | shaft main body to which the urging | biasing force was given is pushed and fixed to the 2nd fixing | fixed part.

  In addition, as a specific example of the place where the first sliding contact portion is provided, for example, a notch for inserting the second shaft main body into the first shaft main body may be provided. That is, the inner surface of this notch and the surface on the side opposite to the end pushed into the first fixing portion can be the first sliding contact portion. For example, the first sliding contact portion can be provided as a surface parallel to the second inclined surface. In this case, as the second inclined surface, for example, an end portion on the side inserted into the notch of the first shaft main body can be used. More specifically, for example, the end surface of the second shaft main body on the side inserted into the notch can be used as the second sliding contact portion. Accordingly, when the first shaft main body is pushed into the first fixed portion and the first sliding contact portion presses the second inclined surface, the second inclined surface can slide on the first sliding contact portion. Thus, the pushed force is converted into a force in a direction orthogonal to the pushed force and can be transmitted to the second shaft main body.

The first sliding contact portion is not limited to the above. For example, the first sliding contact portion may be formed in a spherical shape instead of a flat surface, or a protruding portion is provided on the side surface of the first shaft main body, and one surface of the protruding portion is the first surface. It may be a sliding contact portion.
Moreover, it is not restricted to the above also as a 2nd inclined surface, You may provide a 2nd inclined surface other than an edge part.
Note that the second inclined surface does not necessarily need to be a flat surface. For example, in order to make the second inclined surface and the first sliding contact portion slide more smoothly, a guide groove is provided on the second inclined surface, and the first sliding contact portion can slide along the guide groove. good.

(Operation of the Invention of Claim 3)
In such a fixture, when the first shaft main body is pushed into the first fixing portion in the axial orthogonal state, when the second shaft main body comes into contact with the movement restricting member, a biasing force is applied to the second shaft main body. Given. Thereby, when the first shaft main body is pushed into the first fixing portion and fixed, the second shaft main body is simultaneously pushed into the second fixing portion and fixed.
(Claim 4)
The invention described in claim 4 has the following characteristics in addition to the features of the invention described in claim 1 described above.

  That is, the force direction conversion mechanism is composed of at least a sandwiching part 110 provided in the first shaft body 82 and a sandwiched part 113 provided in the second shaft body 91. A right split piece 111 provided on a side of the first shaft body 82 that is pushed into the first fixed portion 61 and extending in a direction of being pushed into the first fixed portion 61, and a predetermined interval from the right split piece 111. The left split piece 112 extending so as to be substantially parallel to the right split piece 111, and the sandwiched portion 113 is the end of the second shaft main body 91 that is pushed into the second fixed portion 62. Provided on the side surface in the vicinity of the opposite end and formed so as to be sandwiched between the right divided piece 111 and the left divided piece 112, and the right divided piece 111 and the left divided piece 112 are the second shaft body 91. When the first shaft main body 82 is pushed into the first fixed portion 61 in a state where the sandwiched portion 113 is sandwiched, the first shaft As the body 82 is pushed in, the first fixed portion 61 presses the right divided piece 111 and the left divided piece 112 in a direction approaching each other, so that the right divided piece 111 and the left divided piece 112 become the second shaft body. 91 is pushed out, and an urging force in the direction of the second fixed portion 62 is applied to the second shaft main body 91.

Here, the “clamping portion” is provided on the side that is pushed into the first fixed portion of the first shaft main body, and extends in the direction pushed into the first fixed portion, and the right divided piece and a predetermined interval. And a left divided piece extending substantially parallel to the right divided piece. For example, a mode in which an axial slit-shaped notch is provided so as to open at the end on the side to be pushed into the first fixed portion, and is divided into a right divided piece and a left divided piece can be considered.
The “held portion” is provided on the side surface near the end opposite to the end that is pushed into the second fixed portion of the second shaft body. The sandwiched portion is formed so as to be sandwiched between the right divided piece and the left divided piece. For example, when the slit-shaped notch as described above is provided in the first shaft main body, the sandwiched portion of the second shaft main body is inserted into the notch and held by the right divided piece and the left divided piece. Such an embodiment is conceivable.

As described above, the right split piece and the left split piece constituting the sandwiching portion of the first shaft body are formed so as to be able to sandwich the sandwiched portion of the second shaft body. A direction changing mechanism is configured. That is, when the first shaft main body is pushed into the first fixing portion with the right divided piece and the left divided piece sandwiching the sandwiched portion of the second shaft main body, the first fixing is performed as the first shaft main body is pushed. When the part presses the right and left divided pieces in a direction approaching each other, the right divided piece and the left divided piece push out the second shaft body, and the second shaft body is attached to the second fixed portion direction. It is formed to give power.
Specifically, for example, when the slit-shaped notch as described above is provided in the first shaft body, the outer diameter near the end of the first shaft body that is pushed into the first fixing portion is An aspect in which it is formed slightly larger than the inner diameter of the fixed portion is conceivable. In this case, when the first shaft main body is pushed into the first fixing portion, the right divided piece and the left divided piece are pressed in the direction of closing the notch of the first shaft main body. Thereby, the force direction conversion mechanism functions. That is, when the right divided piece and the left divided piece are pressed in this way, the sandwiched portion of the second shaft body sandwiched between the right divided piece and the left divided piece is pushed out, and the second shaft main body is pushed. A biasing force is given. And the 2nd axis | shaft main body to which the urging | biasing force was given is pushed in and fixed to the 2nd fixing | fixed part.

  The shape of the right divided piece and the left divided piece is not particularly limited. For example, a plate shape may be sufficient and a column shape may be sufficient. Moreover, you may provide an inclination in the contact surface with the to-be-held part of a left division piece and a right division piece so that it may be easy to push out the to-be-held part of a 2nd axis | shaft main body. That is, assuming that the side into which the second shaft main body is pushed is the front side and the side opposite to the front side is the back side, the left divided piece and the right divided piece move toward each other from the front side to the back side. You may form so that it may approach, ie, the space | interval of a left division piece and a right division piece may become narrow as it goes to the back side from this side. In addition, the contact surface of the left divided piece and the right divided piece with the held portion may be formed into a curved surface.

In addition, although the left divided piece extends to be substantially parallel to the right divided piece, it does not have to be completely parallel, and in the same direction so that the sandwiched portion of the second shaft body can be sandwiched. Anything that extends can be used.
Further, as a specific shape of the sandwiched portion of the second shaft main body, for example, a portion that contacts the right split piece of the first shaft main body is a right side portion, and a portion that contacts the left split piece of the first shaft main body is When the rear end is the end opposite to being pushed into the second fixed portion of the second shaft body, the right side and the left side gradually approach each other toward the rear end. can do. That is, it can be formed so as to be gradually tapered toward the rear end in a conical shape or a truncated cone shape. Further, the right side portion and the left side portion are provided as planes, and these planes are inclined so as to approach each other toward the rear end, so that a wedge shape can be obtained. Furthermore, the rear end may be hemispherically rounded. Thus, when the rear end side is formed in a conical shape, a truncated cone shape, a wedge shape, a hemispherical shape, or the like, an urging force can be reliably applied to the second shaft main body. The shape on the rear end side of the second shaft main body is not limited to the shape as described above.

(Operation of the Invention of Claim 4)
In such a fixture, when the first shaft main body is pushed into the first fixed portion in the axis orthogonal state, the second shaft main body is pushed out and the second shaft main body is pushed out. A biasing force is applied to the main body. Thus, when the first shaft main body is pushed into the first fixing portion and fixed, the second shaft main body is simultaneously pushed into the second fixing portion and fixed.
(Claim 5)
The invention described in claim 5 is characterized by the following in addition to the features of the invention described in any one of claims 1-4.

  That is, the first shaft main body 82 is provided with a first locking claw portion 86 near the end to be pushed into the first fixing portion 61. When the shaft main body 82 is pushed into the first fixing portion 61 and fixed, the shaft main body 82 engages with the first fixing portion 61 to function as a retaining member, and the first shaft main body 82 Part 83, and by separating the first separating part 83 from the first shaft main body 82, the first shaft main body 82 fixed to the first fixing part 61 other than the first separating part 83 The second shaft main body 91 has a second locking claw portion 94 in the vicinity of the end to be pushed into the second fixing portion 62. The second locking claw portion 94 is engaged with the second fixing portion 62 when the second shaft main body 91 is pushed into the second fixing portion 62 and fixed. The second shaft main body 91 has a second separating portion 96, and the second fixing portion 62 is separated by separating the second separating portion 96 from the second shaft main body 91. The second shaft main body 91 fixed to the second fixing portion 62 is formed such that a portion other than the second separation portion 96 can be removed from the second fixing portion 62.

In other words, the fixture described in this claim can be provided with a locking claw portion that acts as a retaining member on the first shaft body and the second shaft body, and can be removed from the fixing portion. The main feature is that a separation portion is provided.
The “first locking claw portion” is provided in the vicinity of the end that is pushed into the first fixed portion of the first shaft main body. And when this 1st axis | shaft main body is pushed in and fixed to the 1st fixing | fixed part, this 1st latching claw part engages with a 1st fixing | fixed part, and functions as a retaining. That is, for example, by engaging with the peripheral edge of the first fixing part or the engaging part provided in the first fixing part, the first shaft body pushed and fixed into the first fixing part falls off from the first fixing part. This is intended to prevent this. For example, in the case where the first shaft main body is formed so as to penetrate the first fixing portion, the opening edge of the first fixing portion is the opening edge opposite to the side on which the first shaft main body is inserted. It is good also as meshing so that a 1st latching claw part may be hooked. Moreover, a hole, a groove, or the like may be provided as an engaging portion in the first fixed portion, and the first locking claw portion may be engaged with the hole, the groove, or the like. In any case, when the first shaft main body is pushed more than a certain amount into the first fixed portion, the first locking claw portion is arranged so that it does not come out in the direction opposite to the pushed direction. What is necessary is just to mesh with the engaging part provided in the periphery or the 1st fixing | fixed part.

  Incidentally, the first locking claw portion is formed so as to have a portion protruding in the radial direction so as to be wider than at least the minimum inner diameter portion of the first fixing portion in order to function as a retaining stopper. And even if it is formed in this way, the first locking claw portion is formed so as not to interfere with the pressing when the first shaft main body is pressed into the first fixing portion. That is, for example, when the first locking claw portion has elasticity, when the first shaft main body is pushed into the first fixing portion, the first locking claw portion is opened on the inner surface or the opening of the first fixing portion. A mode is conceivable in which the edge is pressed radially inward to be deformed and formed so as to be able to be pushed into the first fixing portion. Further, since the slit-shaped gap is provided in the axial direction of the first shaft main body, the first shaft main body can be opened to the inner surface or the opening of the first fixed portion when the first shaft main body is pushed into the first fixing portion. A mode is also conceivable in which the edge is pressed radially inward to reduce the diameter and can be pushed into the first fixed portion.

As a more specific example of the shape of the first locking claw portion, for example, the outer diameter of the first shaft main body is once expanded near the end to be pushed into the first fixing portion, and then further fixed to the first fixing portion. A shape that gradually decreases in diameter as it goes in the direction of being pushed into the part is conceivable. Further, the shape is not limited to the shape in which the entire outer diameter is expanded and contracted, but only a part of the outer periphery protrudes in the vicinity of the end to be pushed into the first fixed portion, and then is further pushed into the first fixed portion. The shape may be such that the protrusions gradually become smaller toward the head. In other words, the first locking claw portion may be formed of a plurality of separated portions.
The “first separation portion” is provided on the first shaft main body and is separable from the first shaft main body. Then, by separating the first separation part from the first shaft main body, it is possible to remove the part other than the first separation part from the first fixing part among the first shaft main body fixed to the first fixing part. Is formed. That is, the first shaft body that is pushed into and fixed to the first fixing part does not fall off by the first locking claw part, but is pulled out from the first fixing part by separating the first separating part. Can be done. As a specific aspect of the first separating portion, for example, a head functioning as a stopper is provided at the end opposite to the end of the first shaft body that is pushed into the first fixing portion. The part can be a first separation part. In other words, it is conceivable that the first shaft body cannot be removed from the first fixed part without threading the head. Further, as another aspect, the first locking claw portion is formed so that the first locking claw portion is peeled off from the first shaft main body when the first shaft main body is pulled out from the first fixed portion. It is also conceivable that the first shaft main body cannot be pulled out from the first fixed part without destroying.

  The “second locking claw portion” is provided in the vicinity of the end that is pushed into the second fixed portion of the second shaft main body. And when this 2nd axis | shaft main body is pushed in and fixed to the 2nd fixing | fixed part, this 2nd latching claw part engages with the 2nd fixing | fixed part, and functions as a retaining. That is, for example, by engaging with the peripheral edge of the second fixing part or the engaging part provided in the second fixing part, the second shaft body pushed and fixed into the second fixing part falls off from the second fixing part. This is intended to prevent this. For example, in the case where the second shaft main body is formed so as to pass through the second fixing portion, the opening edge of the second fixing portion is the opening edge opposite to the side on which the second shaft main body is inserted. It is good also as meshing so that a 2nd latching claw part may be hooked on. Further, a hole, a groove, or the like may be provided as an engaging portion in the second fixing portion, and the second locking claw portion may be engaged with the hole, the groove, or the like. In any case, when the second shaft main body is pushed into the second fixed portion more than two times, the second locking claw portion is prevented from coming out in the direction opposite to the pushed direction. As long as it engages with the engaging portion provided in the peripheral edge or the second fixing portion.

  Incidentally, the second locking claw portion is formed so as to have a portion protruding in the radial direction so as to be wider than at least the minimum inner diameter portion of the second fixing portion in order to function as a retaining member. And even if it forms in this way, this 2nd latching claw part is formed so that when the 2nd axis | shaft main body is pushed in to a 2nd fixing | fixed part, it does not become the hindrance of the pushing. That is, for example, when the second locking claw portion has elasticity, when the second shaft main body is pushed into the second fixing portion, the second locking claw portion opens or opens on the inner surface of the second fixing portion. A mode is conceivable in which the edge is pressed radially inward to be deformed and formed so as to be able to be pushed into the second fixed portion. In addition, since the slit-shaped gap is provided in the axial direction of the second shaft main body, the second shaft main body is opened to the inner surface or the opening of the second fixed portion when the second shaft main body is pushed into the second fixing portion. A mode is also conceivable in which the edge is pressed radially inward to reduce the diameter and can be pushed into the second fixed portion.

As a more specific example of the shape of the second locking claw portion, for example, the outer diameter of the second shaft main body is once expanded in the vicinity of the end to be pushed into the second fixing portion, and then the second fixing is further performed. A shape that gradually decreases in diameter as it goes in the direction of being pushed into the part is conceivable. Further, the shape is not limited to the shape in which the entire outer diameter is expanded and contracted, but only a part of the outer periphery protrudes in the vicinity of the end to be pushed into the second fixing portion, and then further pushed into the second fixing portion. The shape may be such that the protrusions gradually become smaller toward the head. That is, a second locking claw portion may be formed of a plurality of separated portions.
The “second separating portion” is provided in the second shaft main body and is separable from the second shaft main body. Then, by separating the second separation portion from the second shaft main body, it is possible to remove the portion other than the second separation portion from the second fixed portion of the second shaft main body fixed to the second fixing portion. Is formed. That is, the second shaft main body pushed and fixed to the second fixing portion does not fall off by the second locking claw portion, but is pulled out from the second fixing portion by separating the second separation portion. Can be done. As a specific aspect of the second separation part, for example, a head functioning as a stopper is provided at the end opposite to the end of the second shaft body that is pushed into the second fixed part. The part can be a second separation part. That is, it is conceivable that the second shaft main body cannot be removed from the second fixed portion without threading the head. As another aspect, the second locking claw portion is formed so that the second locking claw portion is peeled off from the second shaft body when the second shaft main body is pulled out from the second fixed portion. It is also conceivable that the second shaft main body cannot be pulled out from the second fixed part without destroying.

The first fixing portion 61 includes a first base shaft hole 65 that is a through hole provided in the base portion 51 and a first cover shaft hole 72 that is a through hole provided in the cover portion 52. The first base shaft hole 65 and the first cover shaft hole 72 are formed so that the first shaft body 82 can pass therethrough.

The second fixing portion 62 includes a second base shaft hole 66 that is a through hole provided in the base portion 51 and a second cover shaft hole 73 that is a through hole provided in the cover portion 52. The second base shaft hole 66 and the second cover shaft hole 73 are formed so that the second shaft main body 91 can pass therethrough.
In the present embodiment, the first base shaft hole 65 of the base portion 51 and the first cover shaft hole 72 of the cover portion 52 form the first fixing portion 61 according to the claims, and the base portion The second base shaft hole 66 of 51 and the second cover shaft hole 73 of the cover portion 52 form the second fixing portion 62 according to the claims.
Next, how the fixing device 81 is pushed into one of the caulking portions 53 will be briefly described with reference to FIG.

  FIG. 7 is an explanatory diagram showing a direction in which the fixing tool 81 is pushed. As shown in this figure, the caulking portion 53 according to the present embodiment pushes and fixes the fixing member 81 after the base portion 51 and the cover portion 52 are overlapped, thereby connecting the base portion 51 and the cover portion 52 together. It can be fixed and sealed. More specifically, the cover portion 52 is integrally formed with a fixture cover 75 protruding outward on a wall surface in close contact with the side plate of the base portion 51 that forms the control board housing portion 26. The fixture cover 75 has a substantially quadrangular prism shape formed so as to cover the first base shaft hole 65 of the base portion 51. Then, the surface on the side into which the fixing tool 81 is pushed is recessed to form a fixing tool insertion port 76. Also, a first cover shaft hole 72 is formed in the bottom of the fixing tool insertion port 76 that is depressed in a concave shape, so that the first shaft main body 82 of the fixing device 81 can be pushed in. When the fixture 81 is pushed in from the fixture insertion port 76, the fixture 81 pushed and fixed is covered with the fixture cover 75.

Although not shown, since the first base shaft hole 65 of the base portion 51 is provided in the direction communicating with the first cover shaft hole 72, the first shaft body 82 is pushed into the first cover shaft hole 72. Thereafter, the first shaft main body 82 is pushed into the first base shaft hole 65. That is, when the fixture 81 is pushed in with the base portion 51 and the cover portion 52 being overlapped, the first shaft main body 82 is moved to the first base shaft hole 65 of the base portion 51 and the first cover shaft hole of the cover portion 52. 72 can be pushed through.
Further, the fixing shaft insertion slot 76 has a second shaft insertion slit 74 so that the second shaft body 91 can pass when the first shaft body 82 is passed through the first cover shaft hole 72.

That is, since the second shaft insertion slit 74 is formed, when the first shaft main body 82 is passed through the first cover shaft hole 72, the second shaft main body 91 is brought into the fixture cover 75. It is possible to insert. In addition, although not shown in the figure, the second base shaft hole 66 of the base portion 51 and the second cover shaft hole 73 of the cover portion 52 communicate with each other in the direction in which the second shaft main body 91 is pushed. It is formed to do. For this reason, when the second shaft main body 91 is pushed in this state, the second shaft main body 91 is pushed through the second base shaft hole 66 of the base portion 51 and the second cover shaft hole 73 of the cover portion 52. It is possible to be

(How to use the fixture 81)
Next, a method of using the fixture 81 according to the present embodiment will be described in more detail by dividing it into the following procedures.
(1) Procedure 1: Insert the second shaft main body 91 into the first shaft main body 82 (2) Procedure 2: superimpose the base 51 and the cover 52 (3) Procedure 3: set the fixture 81 (4) ) Procedure 4: Pushing in the fixture 81 In the following description, "down" means the direction in which the first shaft body 82 is pushed, and "up" means the first shaft body 82 is pushed in. Direction means the direction in which the second shaft main body 91 is pushed in. When saying “back”, the direction opposite to the direction in which the second shaft main body 91 is pushed in. Means.

(Procedure 1: Insert the second shaft body 91 into the first shaft body 82)
FIG. 8 is an explanatory diagram showing a movement in which the second shaft main body 91 is inserted into the first shaft main body 82. As shown in this figure, before the fixing member 81 is pushed in, the second shaft body 91 is first inserted into the notch 87 of the first shaft body 82.
(Procedure 2: Overlay the base 51 and the cover 52)
Next, the base portion 51 and the cover portion 52 are overlapped.
With reference to FIG. 9, the relationship between the base portion 51, the cover portion 52, and the fixture 81 will be described, and how the base portion 51 and the cover portion 52 are overlapped will be described.

FIG. 9 is a partially enlarged sectional view of the caulking portion 53. As shown in FIG. 9, the base portion 51 has a first base shaft hole 65 formed in the bottom plate. A second base shaft hole 66 is formed in the side plate standing on the bottom plate.
The cover portion 52 is formed with a wall surface parallel to the side plate of the base portion 51. A second cover shaft hole 73 is formed in the wall surface. When the base portion 51 and the cover portion 52 are overlapped, the wall surface and the side plate of the base portion 51 are disposed so as to contact each other. With this arrangement, the second cover shaft hole 73 can be positioned so as to communicate with the second base shaft hole 66. Further, a movement restricting member 77 protruding rearward is formed at the lower edge of the second base shaft hole 66.

Furthermore, a fixing member cover 75 is formed on the cover portion 52 so as to cover the second cover shaft hole 73 described above. The fixture cover 75 is formed in a substantially quadrangular prism shape protruding rearward. The upper surface of the fixture cover 75 is recessed to form a fixture insertion port 76. A first cover shaft hole 72 penetrating in the vertical direction is formed in the bottom portion of the fixture insertion port 76 that is depressed in a concave shape. The first cover shaft hole 72 can be positioned so as to communicate with the first base shaft hole 65 when the base portion 51 and the cover portion 52 are overlaid as described above.
(Procedure 3: Set fixture 81)
After the base 51 and the cover 52 are overlapped as described above, the fixture 81 is inserted from the fixture insertion port 76 of the cover 52, and the fixture 81 is set.

  FIG. 10 is a cross-sectional view showing a state in which the fixture 81 is inserted and set from the fixture insertion port 76 of the cover portion 52. As shown in this figure, since the second shaft insertion slit 74 is provided in the cover portion 52, the second shaft main body 91 can be inserted into the fixture cover 75. The second shaft main body 91 inserted in this way can be inserted until the lower part abuts against the movement restricting member 77, and beyond that, the second shaft main body 91 cannot be moved downward. In other words, by inserting the second shaft main body 91 along the second shaft insertion slit 74 of the cover portion 52, the lower portion of the second shaft main body 91 abuts on the movement restricting member 77, and the fixture 81 is set. Is possible.

(Procedure 4: Push in the fixture 81)
In the present embodiment, the fixing device 81 is set as described above, and then the first shaft rear end 85 side of the first shaft body 82 is pressed downward to complete the fixing. . That is, in this state, even if the first shaft main body 82 is further pushed down, the second shaft main body 91 is in contact with the movement restricting member 77 and cannot move downward. Since the second inclined surface 95 is slidable along the first inclined surface 88, when the first shaft main body 82 is further pushed down, the second inclined surface 95 is moved along the first inclined surface 88. It will slide. As a result, the force for moving the second shaft main body 91 downward is converted into the force for moving the second shaft main body 91 forward. Specifically, the first inclined surface 88 is inclined by 30 degrees with respect to the axis of the first shaft body 82, and the second inclined surface 95 is inclined by 60 degrees with respect to the axis of the second shaft body 91. Therefore, when the first shaft main body 82 is pushed down, the second shaft main body 91 is pushed forward by a distance half of the pushed-in distance.

FIG. 11 is a cross-sectional view showing a state in which the first shaft main body 82 is further pushed down from the state of FIG. 10 described above. As shown in this figure, the second shaft body 91 is pushed forward by pushing the first shaft body 82 downward.
Since the first locking claw portion 86 of the first shaft body 82 penetrates the first base shaft hole 65 of the base portion 51 and penetrates downward, the lower peripheral edge of the first base shaft hole 65 It is supposed to be caught in. Further, the first separation part 83 is hooked on the upper peripheral edge of the first cover shaft hole 72 in the upper part. Thereby, the first shaft main body 82 is fixed to the base portion 51 and the cover portion 52.

Further, the second locking claw portion 94 of the second shaft main body 91 passes through the second base shaft hole 66 of the base portion 51 and further passes through the second cover shaft hole 73 of the cover portion 52, and moves forward. The second shaft main body 91 is fixed to the base portion 51 and the cover portion 52 by being caught by the front edge of the second cover shaft hole 73 because it has penetrated.
Hereinafter, the manner in which the first locking claw portion 86 and the second locking claw portion 94 function as a retaining member will be described in more detail.
FIG. 12 shows that the first locking claw portion 86 of the first shaft body 82 passes through the first base shaft hole 65 of the base portion 51 and is hooked on the lower peripheral edge of the first base shaft hole 65 to prevent the first shaft main body 82 from coming off. It is sectional drawing showing a mode that it functions. What is shown as (a) shows before penetration of the first locking claw portion 86, and what is shown as (b) shows after penetration of the first locking claw portion 86, respectively. As shown in this figure, the first locking claw portion 86 is opened outwardly larger than the inner diameter of the first base shaft hole 65 of the base portion 51, and is formed so that it cannot pass as it is. However, when the first shaft main body 82 is pushed into the first base shaft hole 65, the first shaft main body 82 is pressed against the inner surface of the first base shaft hole 65 so that the diameter of the first shaft main body 82 is reduced. The diameter of the first shaft main body 82 can be reduced by providing a slit in the axial direction of the first shaft main body 82. The first shaft main body 82 can pass through the first base shaft hole 65 by reducing the diameter. After the penetration, the first locking claw portion 86 returns to the opened state again, so that the first locking claw portion 86 functions as a retaining stopper.

  FIG. 13 shows that the second locking claw portion 94 of the second shaft main body 91 passes through the second cover shaft hole 73 of the cover portion 52 and further passes through the second base shaft hole 66 of the base portion 51. FIG. 6 is a cross-sectional view showing a state where the hook is caught on the front side edge of the second base shaft hole 66 of the base portion 51 and functions as a retainer. What is shown as (a) is before penetration of the second locking claw portion 94, and what is shown as (b) is after penetration of the second locking claw portion 94. As shown in this figure, the second locking claw portion 94 is opened to the outside larger than the inner diameter of the second cover shaft hole 73 of the cover portion 52 and the second base shaft hole 66 of the base portion 51. It is formed so that it cannot pass. However, when the second shaft main body 91 is pushed into the second cover shaft hole 73 and the second base shaft hole 66, it is pressed against the inner surfaces of the second cover shaft hole 73 and the second base shaft hole 66, thereby The claw portion 94 bends inward. Then, the second shaft main body 91 can penetrate the second cover shaft hole 73 and the second base shaft hole 66 by bending. Then, after the penetration, the second locking claw portion 94 returns to the opened state again, so that the second locking claw portion 94 functions as a retaining stopper.

The inner diameter of the second cover shaft hole 73 is slightly larger than the inner diameter of the second base shaft hole 66. This is because when the second shaft main body 91 is pushed, This is for smoothly bending the portion 94 to the inside. However, as a matter of course, the inner diameter of the second cover shaft hole 73 does not have to be larger than the inner diameter of the second base shaft hole 66.
(How to check fraud)
Next, a method for confirming fraud on the substrate case 25 sealed as described above will be described. That is, a method for confirming whether or not the sealed substrate case 25 has been opened illegally will be described.

The fixing tool 81 in the present embodiment is formed so that the fixed state cannot be released unless the first separating portion 83 and the second separating portion 96 are destroyed as described above. Therefore, in other words, if it can be confirmed whether either the first separation part 83 or the second separation part 96 is broken, it can be confirmed whether the sealed substrate case 25 has been opened illegally. .
FIG. 14 is an external view of the base case as viewed from the rear and the top. And (a) shows the state by which the fixing tool 81 was fixed. As shown in this figure, it can be confirmed whether either the first separation part 83 or the second separation part 96 is broken, when viewed from either the rear direction or the upward direction. It has become. That is, depending on the location where the base case is fixed, it is considered that the state of the fixture 81 cannot be confirmed or difficult from a specific direction. However, if the fixture 81 according to the present embodiment is used, such inconvenience is caused. Does not occur.

Further, what is shown as (b) in FIG. 14 shows a state before the fixing tool 81 is fixed, but it is also easy to grasp that the fixing tool 81 is not fixed as described above. It has become. That is, it is possible to confirm whether or not the fixture 81 is fixed when viewed from either the rear direction or the upward direction. Thereby, even when the seal is incomplete due to carelessness, for example, it is possible to easily grasp that the seal is incomplete.
(Summary)
In the present embodiment, because it is configured as described above, when the first shaft body 82 is pushed into the first base shaft hole 65 of the base portion 51 and the first cover shaft hole 72 of the cover portion 52, The second shaft main body 91 is pushed into the second base shaft hole 66 of the base portion 51 and the second cover shaft hole 73 of the cover portion 52. The first locking claw portion 86 of the first shaft main body 82 functions as a retainer, so that the first shaft main body 82 can be removed without threading the first separating portion 83 of the first shaft main body 82. There is no such thing. Further, since the second locking claw portion 94 of the second shaft main body 91 functions as a retaining stopper, the second locking claw portion 94 (that is, the second separation portion 96) of the second shaft main body 91 is not separated. The second shaft main body 91 is prevented from coming off. For this reason, when the substrate case 25 is illegally opened, it is possible to grasp an illegal act by observing the damage state of the first shaft main body 82 and the second shaft main body 91. Further, since the first shaft main body 82 and the second shaft main body 91 are double-sealed, it is formed so that it is more difficult to perform an illegal act without leaving a trace. Furthermore, since the shaft of the first shaft body 82 and the shaft of the second shaft body 91 are fixed so as to be orthogonal to each other, at least the first shaft body 82 and the second shaft body 91 have a Any one of the uniaxial main body 82 and the second axial main body 91 is formed so as to make it easy to see the fact that it has been destroyed from any direction.

  In the present embodiment, the first shaft body 82 and the second shaft body 91 are formed so as to be orthogonal to each other by inserting the second shaft body 91 into the first shaft body 82.

Further, by fixing the first shaft main body 82 and the second shaft main body 91 by the connecting member 100, the first shaft main body 82 and the second shaft are fixed in the state before being fixed to the first fixing portion and the second fixing portion. You may form so that the main body 91 may always orthogonally cross. In this case, the connecting member 100 needs to be formed so as to be breakable. That is, when the first shaft main body 82 is pushed into the first fixing portion 61 and the second shaft main body 91 is pressed against the first inclined surface 88 and slides, the connecting member 100 is broken and the first shaft main body is broken. It is necessary to form so that the fixed state of 82 and the second shaft main body 91 is released. As another example, the second shaft main body 91 may be fixed to the movement restricting member 77 so that the second shaft main body 91 can take the state shown in FIG. In this case, the first shaft main body 82 and the second shaft main body 91 are not connected by the connecting member 100. When the first shaft main body 82 is inserted from the fixture insertion port 76 in this state, the first inclined surface 88 of the first shaft main body 82 and the first inclined surface 88 of the second shaft main body 91 are slidably contacted. By doing so, the first shaft body 82 and the second shaft body 91 may be in a state of being orthogonal to each other.

  In the present embodiment, both the first inclined surface 88 and the second inclined surface 95 are included, and the first inclined surface 88 functions as the first sliding contact portion, and the second inclined surface 95 However, the present invention is not limited to this. That is, the first sliding contact portion may be provided instead of having the first inclined surface 88, or the second sliding contact portion may be provided instead of having the second inclined surface 95. Specifically, in the case where the first sliding contact portion is provided instead of having the first inclined surface 88, the surface forming the first inclined surface 88 in the present embodiment is, for example, a hemispherical surface protruding downward can do. Similarly, in the case where the second sliding contact portion is provided instead of having the second inclined surface 95, the surface forming the second inclined surface 95 in the present embodiment is, for example, a hemispherical surface protruding rearward. Can do.

In the present embodiment, the first inclined surface 88 and the second inclined surface 95 are flat surfaces, but are not necessarily limited thereto. For example, in order to slide the first inclined surface 88 and the second inclined surface 95 more smoothly, a guide groove that engages the first inclined surface 88 and the second inclined surface 95 is provided, and the second inclined surface is provided. 95 may be formed to slide along the guide groove.
Further, although the first shaft main body 82 and the second shaft main body 91 according to the present embodiment are structured such that the moving direction is limited to one, the present invention is not limited to this. That is, it may be a nail that is simply pushed and fixed.

Specifically, when the second shaft rear end 93 side of the second shaft main body 91 is inserted into a notch 87 provided in the first shaft main body 82, the sandwiched portion 113 becomes the right divided piece 111 and the left divided piece 112. It is formed to be held by.
(Actual usage example)
Next, an actual usage example of the fixture 81 according to the present embodiment will be described. That is, when the first shaft main body 82 is pushed into the first fixed portion 61, the force to be pushed is converted into a force in a direction orthogonal to the pushed force and transmitted to the second shaft main body 91. explain in detail.

First, the end of the second shaft main body 91 on the side to be held is inserted into a notch 87 provided in the first shaft main body 82. Accordingly, the right divided piece 111 and the left divided piece 112 of the first shaft main body 82 are held in a state where the held portion of the second shaft main body 91 is sandwiched and held.
Then, in a state where the second shaft main body 91 is inserted into the notch 87 of the first shaft main body 82, the fixing tool 81 is set on the fixing partner (for example, the base portion 51 and the cover portion 52). This state is shown as (a-1) and (a-2) in FIG.
When the first shaft main body 82 is pushed into the first fixing portion 61 from this state, the second shaft main body 91 is moved to the second fixing portion 62 as shown in FIGS. 16 (b-1) and (b-2). It is formed so as to be pushed and fixed.

That is, a protrusion (first locking claw portion 86) is provided in the vicinity of the first shaft tip 84, and the width of this protrusion portion is formed to be slightly larger than the width of the inner diameter of the first fixing portion 61. Yes. As a result, when the first shaft main body 82 is pushed into the first fixed portion 61, the first fixed portion 61 presses the right divided piece 111 and the left divided piece 112 in a direction approaching each other. Then, when the right divided piece 111 and the left divided piece 112 are pressed in this way, the held portion of the second shaft main body 91 sandwiched between the right divided piece 111 and the left divided piece 112 is pushed out, A biasing force is applied to the second shaft body 91.
