Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a hinge.

[0002]

BACKGROUND OF THE INVENTION Hinges are used in a variety of applications. It is generally used for the base end of a door, etc.,
For example, it may be used in a game machine mounting island.

An example of a game machine mounting island will be described. A gaming machine (including both a pachinko gaming machine and a rotating body type gaming machine) is a gaming machine mounting island (in this specification, the "gaming machine mounting island" may be simply referred to as an "island"). Fixed to a structure called. This fixing is performed by, for example, attaching the pachinko gaming machine to a mounting frame configured by assembling a wooden member in a rectangular shape, and mounting the mounting frame to the island (note that in this conventional technique, the pachinko gaming machine is used. I will explain the island where is attached.

An opening along the lengthwise direction of the island is provided above the island, and a decorative plate for closing the opening is attached to the opening (herein, "decorative plate" is referred to as "decorative plate"). , A plate located above the gaming machine, which is equipped with at least a calling lamp when the island is used. The decorative plate is opened when a toy for supplying balls, which is provided above the island, is clogged, or when an abnormality occurs in the wiring made above the island. A person involved in the game hall looks into the open opening or puts his or her hand in to check the condition of the toys and wiring, or to take necessary measures. The decorative plate is attached to the gaming machine mounting island body through a hinge so as to allow such opening. Here, a hinge is used.

A hinge used for such an application includes a hinge base and a hinge arm whose base end is supported by the hinge base via a main shaft, and is rotatable with respect to the hinge base. Not only is the hinge arm capable of rotating from the closed position to an open position where the angle formed with the hinge base is larger than the closed position, but the hinge arm does not move temporarily with respect to the hinge base in the open position. (The fixing of the hinge arm to the hinge base in this specification means that the hinge arm described above cannot rotate in the direction toward the closed position.).

[0006] Such a hinge, for which "temporary fixing" is required as a function thereof, has a complicated structure, for example, a member such as a sticker bar for "temporary fixing" is required. It tends to become expensive, and the cost tends to be high. Further, when the hinge is applied to a game machine mounting island or other relatively narrow place, unless the operating range of the components forming the hinge is narrowed, interference with the surroundings may occur.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to make the hinge capable of realizing the above-mentioned "temporary fixing" simple and inexpensive, and in addition, It is an object of the present invention to narrow the operating range of the components that compose it and to provide a game machine mounting island to which such a hinge is applied.

[0008]

In order to solve the above problems, the present invention provides the following hinges. The hinge includes a hinge base and a hinge arm whose base end is supported by the hinge base via a main shaft, and the hinge arm forms an angle between the hinge arm and the hinge base from the closed position. The hinge base can be rotated to an open position larger than the position, and can be temporarily fixed to the hinge base in the open position. The hinge base is rotatably attached to an auxiliary shaft parallel to the main shaft, and includes a locking groove having a first locking portion and a second locking portion facing each other. A locking body is provided. In addition, inside the hinge arm, there is provided a first contact portion that can contact the first locking portion and a second contact portion that can contact the second locking portion. While the body and the hinge arm are approaching the open position from the closed position, the tip of the body comes into contact with the rotary locking body, so that the hinge arm rotates in the direction from the open position to the closed position. The rotary locking body is rotated to a lock position such that the first contacting portion and the second contacting portion of the moving contacting body enter into the locking groove, and the state is the same. When the hinge arm is rotated in the direction, the tip of the hinge arm comes into contact with the rotary locking body, so that the hinge arm rotates in the direction from the open position to the closed position. The first contact portion and the second contact portion of the body are brought to a free position where they contact the outside of the locking groove. A hammer which is a rolling engagement member so as to rotate, is provided. With this, when the hinge arm is rotated from the closed position to the open position, the hinge is rotated to the lock position by the hammer that rotates together with the hinge arm. The first abutment portion and the second abutment portion, the first abutment portion of the abutment body entering the engagement groove by being rotated with the rotation of the hinge arm,
The hinge base of the hinge arm is temporarily fixed by the contact of the second contact portion with the second contact portion, and the hinge arm is further rotated in the same direction from that state. Occasionally, the first contact portion of the contact body is rotated by the rotation of the hinge arm to the outside of the locking groove of the rotary body that has been rotated to the free position by a hammer that rotates together with it. By contacting the second contact portion, the hinge arm that is not fixed to the hinge base can be rotated to the closed position. This hinge realizes the above-mentioned "temporary fixing" with only three parts, that is, the contact body, the rotation locking body, and the hammer, and the structure is simple and inexpensive. The simplicity of the structure of the hinge is due to the fact that the hammer for rotating the rotary locking body is attached to the hinge arm, so that the hinge rotates as the hinge arm rotates. In this hinge, since the motion of the hinge arm and the motion of the hammer are of the same type, a mechanism for changing the rotary motion to the linear motion, which is necessary when the hammer is linearly moved, is unnecessary. Therefore, the structure is simple. In this specification, "inside the hinge base"
The term "indicates the side of the hinge base that faces the hinge arm, and the term" inside the hinge arm "refers to the side of the hinge arm that faces the hinge base.

The abutment body and the hammer in the hinge of the present invention are attached to the hinge arm, whether directly or indirectly through other parts, and are rotated as the hinge arm rotates. It is designed to do dynamic exercises.
When the abutment body and the hammer are directly fixed to the hinge arm, the angle and direction of rotation performed by the abutment body and the hammer are the same as the rotation performed by the hinge arm. However, the contact members and the hammer do not necessarily have to have such rotation angles and directions. For example, in the hinge of the present invention, the abutment body is adapted to rotate at the same direction and the same angle as the hinge arm, and the hammer is in the same direction as the hinge arm is rotated, It may be configured to rotate at a smaller angle. In order to rotate the hammer at a smaller angle in the same direction as the hinge arm rotates, for example, the hammer is attached to the abutment body and the hinge arm is rotated at a predetermined angle. It may be configured so that the hinge arm does not rotate when the hinge arm moves closer to the closed position. More specifically, the hammer is configured to be capable of being separated from the contact body by a predetermined limit angle, and is urged by an elastic body in a direction away from the contact body, and the hinge arm However, when the closed position is closer to the open position than the limit angle is,
After the elastic body is urged away from the abutting body to reach the limit angle, the hinge arm is rotated to rotate so that the hinge arm moves from the open position to the closed position. In such a case, a part of the hinge base abuts on a predetermined part of the hinge base so that the hinge arm can be prevented from being rotated by the rotation of the hinge arm against the bias of the elastic body.

The shape of the contact body is not limited as long as it has the first contact portion and the second contact portion as described above. For example, the abutment body can be configured such that the center angle is a fan shape with an angle of about 90 degrees, and one of two radii forming a part of the circumference of the fan shape is along the inner side surface of the hinge arm. . In this case, the first contact portion and the second contact portion can be provided in the vicinity of a portion where the other radius and the arc intersect. In this case, one of the first locking portion and the second locking portion is positioned on the other side of the radius and the other is positioned on the radius. Further, the hinge arm in this case may be configured to rotate approximately 90 degrees between the closed position and the open position.

As long as the rotary locking body has the first locking portion and the second locking portion, its shape does not matter. The number of locking grooves does not matter. The rotary locking body may have the locking grooves at two opposing positions sandwiching the counter shaft, for example.

This hinge is the "temporary fixing" mentioned above.
May be used where appropriate. However, since the "temporary fixing" in this hinge means that the hinge arm cannot rotate in the direction toward the closed position, this hinge is such that the rotation direction of the hinge arm is in the vertical plane. Moreover, it is most effective when used in a situation where the tip of the hinge arm in the closed position faces the direction directly below. This hinge can be applied to a game machine mounting island. For example, an island main body provided with a game machine mounting portion to which a game machine is mounted on at least one surface thereof, a decorative plate mounted above the gaming machine mounting portion, and the decorative plate being the gaming machine main body. The above-mentioned is used as the hinge of the game machine mounting island, which is provided with a hinge that can be freely opened and closed. In this case, the game machine mounting island is provided with, for example, two upper pillars that regulate the width of the island and a lower pillar that supports these upper pillars from below, and the straight line connecting the upper pillars is the longitudinal direction of the island. A plurality of struts arranged in the longitudinal direction of the island at a predetermined interval in a direction orthogonal to the direction, two vertical members of a length substantially corresponding to the length of the upper stanchions, and adjacent struts Attached to a gaming machine, which is formed into a rectangular shape by two horizontal members having a length corresponding to the distance between them, and which is provided with an auxiliary horizontal member that connects the two vertical members and is parallel to the horizontal member. You may include the island aggregate. In this case, the hinge base of the hinge is attached to each of the lateral members located on the upper side and the auxiliary lateral members (it is also possible to mount only one of them). Other hinges other than this hinge may be appropriately used.) And, the decorative plate is attached to the hinge attached to one of the cross members located on the upper side, and when it is in the closed state. One of the vertical members and the one of the horizontal members which is located on the upper side, an upper decorative plate surrounded by the auxiliary horizontal members so as to close the upper opening, and one which is attached to the auxiliary horizontal members and is closed. Which is located on the lower side of both vertical members and the horizontal member when in the state,
And a lower decorative plate that closes the lower opening surrounded by the auxiliary horizontal member. The merits of dividing the opening into two upper and lower parts and dividing the decorative plate that closes the opening into two upper and lower parts are as follows. Since the decorative board is usually a single piece without upper and lower divisions, when opening it, the decorative board of the single piece is removed from the opening to open the entire opening. By the way, a calling lamp is usually attached below the decorative plate (immediately above the pachinko gaming machine), and when the opening is opened, it is necessary to move a large amount of wiring extending from the calling lamp. In this case, this wiring is an obstacle, and it is actually difficult to move the decorative plate to open the opening. As described above, if the opening and the decorative plate are divided into upper and lower parts, it is not necessary to worry about the wiring of the calling lamp fixed to the decorative plate when the opening is opened, so that workability can be improved. This is the merit of the structure described above.

A paging lamp is usually attached to the decorative plate. The calling lamp may be attached to any part of the decorative plate, more specifically, to either the upper decorative plate or the lower decorative plate. However, in the gaming machine mounting island of the present invention, the lower decorative plate is attached to the decorative lamp. It can be attached. To get the above benefits,
It is preferable to adopt this structure.

The mounting of 42 is performed as shown in FIG. In order to perform such attachment, first, the length of the screw 941C protruding downward from the hinge arm main body 941 is changed to the screw 941C.
And the length of the screw 941E protruding forward from the hinge arm main body 941 is adjusted by rotating the screw 941E. Then, the two locking metal fittings 943 provided on the position adjusting body 942 to which the decorative plates 731 and 732 are attached are put into the two holes 941A provided on the hinge arm main body 941, and then the position adjusting body The 942 is shifted downward in FIG. Thus, the hinge arm main body 94 and the position adjusting body 942 are substantially fixed. However, in this embodiment, the tip of the screw 942E which penetrates the hole 941F provided in the hinge arm main body 94 is further fixed to the position adjusting body. Hole 9 provided in 942
42C is screwed to increase the certainty of fixing. The length of the hole 942F is long enough to correspond to the hole 942C even if the position adjusting body 942 moves in the vertical direction, and the width of the hole 940F is narrower than the head width of the screw 942E. The hinge arm main body 941 and the position adjusting body 942 are securely fixed by screwing the screw 942E. As described above, the fixing work of the hinge arm main body 941 and the position adjusting body 942 is completed.
As described above, since the hinge arm main body 941 and the position adjusting body 942 are basically fixed by one touch, the work load required for the person using the hinge on site is small. As described above, the screw 941C has a head portion having a diameter larger than the width of the positioning groove 944A provided in the positioning metal fitting 944. Therefore, the positioning metal fitting 944 exceeds the head portion of the screw 941. Cannot move downward. As a result, when the hinge arm 940 is in the closed position, the position adjusting body 942 (and thus the fixing portion 942A) is positioned in the downward direction. Since the position adjusting body 942 cannot rise upward against gravity, this results in the positioning of the position adjusting body in the vertical direction. Further, by the above-mentioned work, the position adjusting body 942
The front-back positioning is also performed at the same time. Position adjuster 9
42 is in a state of being floated from the hinge arm body 941 by the length of the screw 941E protruding forward from the hinge arm body 941. In addition, in order to make the alignment in the front-back direction accurate, the above-mentioned leaf spring 943 is used.
B works. The leaf spring 943B applies a force to the hinge arm body 941 and the position adjusting body 942 in a direction in which they are in close contact with each other, so that the floating amount of the position adjusting body 942 from the hinge arm body 941 becomes constant. . As described above, in the hinge of this embodiment, the adjustment of the position adjusting body 942 with respect to the hinge arm main body 941 in the up-down direction and the front-back direction is performed steplessly using the screws. The adjustment of the length of the screw 941C protruding downward from the hinge arm main body 941 and the adjustment of the length of the screw 941E protruding forward from the hinge arm main body 941 can be performed ex post facto. These adjustments may be performed at appropriate points in consideration of the efficiency of work procedures. If the face plates 731, 732 are not sufficiently aligned, posterior adjustment should be made.

When adjusting the vertical position of the position adjusting body 942 with respect to the hinge arm main body 941, particularly when performing a posterior adjustment, an adjusting jig 970 as shown in FIGS. 13 and 14 may be used. it can. In addition, FIG.
It is a FF arrow line view of the adjustment jig 970 shown in FIG.
As shown in the figure, the adjusting jig 970 is formed by bending a plate-like body into a substantially U-shaped cross section, and includes a rear plate 971 and a front plate 972. Back plate 97
1, the length is slightly longer than the front plate 972. Further, both the rear plate 971 and the front plate 972 are provided with a notch that extends upward from the lower side (lower side in FIG. 14) of the center thereof. This adjusting jig 970 is used in the state as shown in FIG. This is because when the vertical position of the position adjusting body 942 relative to the hinge arm main body 941 is adjusted afterwards, the inside of the rear plate 971 is made to follow the surface of the positioning metal fitting 944 on the proximal end side of the hinge arm 940, and The front plate 972 is arranged along the head of the screw 941C (so that this is possible, the rear plate 9 of the adjustment jig 970 is disposed.
The distance from the inside of 71 to the inside of the front plate 972 is made to correspond to the thickness of the positioning fitting 944 + the thickness of the head of the screw 941C. ). At this time, the notch provided in the rear plate 971 straddles the screw rod portion of the screw 941C. In this state, when a screwdriver or the like is inserted through the notch of the front plate 972 and the screw 941C is rotated, the positioning fitting 94
4 is integrated with the head of the screw 941C,
It moves with the up and down movement of C. (To enable this,
The width of the notch provided on the front plate 972 of the adjustment jig 970 is
The diameter is smaller than the head diameter of the screw 941C. ).
As a result, accurate positioning of the position adjusting body 942 is realized. This adjusting jig 970 is used for the position adjusting body 9
It is particularly useful when moving 42 downward relative to hinge arm body 941. Position adjuster 942
Is moved relative to the hinge arm main body 941 by rotating the screw 941C and moving the screw 941C upward, the screw 94 moving upward accordingly.
Since the head of 1C pushes up the positioning fitting 944, the position adjusting body 942 always moves upward. On the other hand, the position adjusting body 942 is attached to the hinge arm main body 94.
Screw 941 when moving upward relative to
Even if you rotate C in the opposite direction and move it downwards,
Only the head of the screw 941C moves downward to move the position adjusting body 9
It is considered that the downward movement of 42 is not performed. Therefore, using the adjustment jig 970,
If the head of the screw 941C is kept in a close contact state, the positioning metal fitting 944 always moves downward together with the head of the screw 941C moving downward by moving the screw 941C downward. In this way, the adjustment jig 9
By using 70, the downward movement of the position adjusting body 942 is surely performed.

The hammer 950 has a shape as shown in FIGS. FIG. 17 shows E of FIG.
FIG. The hammer 950 has a hinge arm 9
It rotates with the rotation of 40, and the above-described rotation locking body 913.
Abutting against and rotating it.

As shown in FIGS. 16 and 17, the hammer 950 includes a hammer guide 951 and a hammer body 9.
And 52. Hammer guide 951
It is formed in a fan shape having a central angle of about 90 degrees. And
A hole 951A for supporting the main shaft 947 is provided near the intersection of the two exposed radii. The hammer guide 951 can rotate while being supported by the main shaft 947. The hammer guide 951 is provided with a guide groove 951B that receives the above-described guide pin 945A provided on the contact body 945. The guide groove 951B is an arc-shaped groove extending along the arc of the hammer guide 951 and penetrates the hammer guide 951. The hammer body 952 is projected from the hammer guide 951. The tip of the hammer body 952 is such that when the hammer body 952 rotates, the tip of the hammer body 952 is the above-mentioned sub shaft 911C.
It is arranged in a position that draws a trajectory that goes to.
The hammer body 952 also constantly receives a force in a direction away from the hinge arm 940 from an elastic body (not shown) (for example, a spring).

The hinge base 94 is attached to the hinge arm 94.
18 to 24 are side views schematically showing a state in which the 0 and the hammer 950 are assembled. The operation of the hinge 900 will be described below with reference to these drawings.

FIG. 18 shows the hinge arm 940 facing downward, that is, in the closed state.

From this state, in the direction of the arrow in FIG.
When the hinge arm 940 is rotated, the situation changes as shown in FIG. That is, the contact body 945 integrated with the hinge arm 940 rotates together with the hinge arm 940. However, at this time, the hammer 9
50 does not start turning. This is because the hammer 950 is always applied with a force in a direction away from the hinge arm 940 by the elastic body. Even if the hinge arm 940 starts to rotate, the hammer 950 that tries to move away from it does not rotate.

When the hinge arm 940 is further rotated in the direction of the arrow in FIG. 18, the situation changes as shown in FIG. In other words, not only the contact body 945 but also the hammer 950 is rotated in accordance with the rotation of the hinge arm 940. This is because the guide pin 945A provided on the contact body 945 of the hinge arm 940 advances while being guided by the guide groove 951B of the hammer 950 and is locked at the end of the guide groove 951B. In this state, even if the hammer 950 is constantly urged in the direction away from the hinge arm 940, the distance (angle) between the hammer 950 and the hinge arm 940 does not further increase. While keeping this state, the contact body 945 and the hammer 950 are rotated.

When the hinge arm 940 is further rotated in the same direction, the situation changes as shown in FIG.
That is, the tip of the hammer 950 (the tip of the hammer body 952) comes into contact with the rotation locking body 913, and the rotation locking body 913 rotates around the sub shaft 911C. The orbit along which the tip of the hammer 950 moves passes through the outside of the sub shaft 911C when viewed from the main shaft 947.
The tip of the hammer 950 hits the lower side of the rotary locking body 913 in the figure. At this time, the rotation locking body 913 is
The first contact portion of the contact body 945 that rotates in the same direction as the hinge arm 940 that rotates in the direction from the open position to the closed position (that is, the direction opposite to the above case) moves, and Two
The contact portion is rotated to the lock position where it enters the locking groove 913B.

From this state, when the hinge arm 940 is rotated in the direction from the open position to the closed position, the first contact portion and the second contact portion at the end of the contact body 945 of the hinge arm 940. 2 in order to enter the locking groove 913B in order.
As shown in FIG. 2, the first locking portion and the second locking portion in the locking groove 913B come into contact with each other in order. As a result, the hinge arm 940 cannot rotate toward the closed position, and is temporarily fixed to the hinge base 910. In this state where the decorative plates 731 and 732 are opened,
Persons involved in the amusement arcade can freely work inside the island S.

From this state, when the hinge arm 940 is rotated in the direction from the closed position to the open position, the contact body 945 and the hammer 950 are rotated accordingly, as shown in FIG. .

The hinge arm 94 is moved in the above-mentioned direction as it is.
When 0 is turned, the situation changes this time, as shown in FIG. That is, the tip of the hammer 950 (the tip of the hammer body 952) comes into contact with the rotation locking body 913, and the rotation locking body 913 rotates around the sub shaft 911C. At this time, the rotation locking body 913 is not attached to the hinge arm 9
The first contact portion and the second contact portion of the contact body 945 that rotates as 40 rotates in the direction from the open position to the closed position contact the outside of the locking groove 913B. It can be rotated to the free position.

From this state, when the hinge arm 940 is rotated in the direction from the open position to the closed position, the contact body 945 of the hinge arm 940 comes into contact with the rotation locking body 913, but the contact body 945. As shown in FIG. 25, the first contact portion and the second contact portion at the end of the
13 does not enter the locking groove 913B. Also, the contact body 9
By being pushed away by 45, the rotation locking body 913 is rotated to a position where it does not interfere with the contact body 945.
Therefore, the hinge arm 940 rotates as it is toward the closed position.

Hinge arm 940 as it is in the above direction
When is rotated, the situation changes as shown in FIG. That is, the hammer 950 stops rotating. This is because the end of the hammer 950 on the side where the hammer body 952 is attached interferes with a predetermined portion inside the base body 911. Accordingly, the rotation of the hinge arm 940 causes the contact body 94 to rotate.
That's only 5.

Then, when the hinge arm 940 is rotated as it is, the hinge arm 940 reaches the closed position similar to that shown in FIG. 18 (FIG. 27).

As described above, the abutment body 945 in this embodiment is designed to rotate at the same angle as the hinge arm 940, but the hammer 950 is, so to speak, folded with respect to the hinge arm 940. By making it possible, the hinge arm 940 can be rotated only within a range of an angle smaller than the rotation of the hinge arm 940. As a result, the hinge according to this embodiment does not require the base body 911 to be upsized.

Returning to the story of the entire gaming machine island. The frame 600 is fixed to the support column 500 as follows. First, a plurality of struts 500 are arranged in the longitudinal direction of the island S at predetermined intervals in such a direction that the straight line connecting the upper struts 510 is orthogonal to the longitudinal direction of the island. The space between the columns 500 is a frame 600.
The length of the horizontal member 620 is assumed to correspond. Then
The frame 600 is fitted between the upper columns 510 of the columns 500 adjacent to each other.

At this time, what kind of gaming machine (which is a pachinko gaming machine in this embodiment) attached to this frame 600 later is like (mainly what is its thickness). Alternatively, the frame 60 may be arranged according to circumstances such as the width of a toy (not shown) for supplying balls of the pachinko gaming machine arranged between the frames 600 facing each other later.
The mounting position of the island S with respect to the column 500 of 0 in the width direction is appropriately adjusted. This adjustment is performed as follows.
First, among the frame holes 611 provided in the vertical member 610 of the frame 600, the one above the vertical member 610 faces any one of the frame holes 611 above the upper support column 510, and the vertical member of the frame holes 611. The frame 600 is fitted between the upper columns 510 of the adjacent columns 500 while the lower part of the column 610 faces the frame hole 611 in the lower part of the upper column 510. Frame hole 6
The mounting position of the frame 600 with respect to the column 500 is provisionally determined depending on which column hole 511 the 11 is exposed to. Then, in this state, the frame hole 611 and the support hole 5
The bolts 680 are inserted through the exposed openings of the frame holes 611 while being positioned inside both of the holes 11. The bolt 680 corresponds to the fixed body in the present invention, and includes a head portion 681 and a screw portion 682,
Of the outer periphery of the screw portion 682, at least the column hole 51
A male screw groove 683 that meshes with the female screw groove 512 on the inner peripheral surface of the support hole 511 is provided in the portion to be inserted into the column 1. While making the bolt 680 engage with the male screw groove 683 on the outer peripheral surface of the screw portion 682 and the female screw groove 512,
The frame hole 611 is penetrated and screwed into the support hole 511. In this way, the frame 600 is attached to the support column 500. The other vertical member 610 of the frame 600 is similarly fixed to the support column 500. Continue the above work,
0, frame 600, support 500, frame 600, ... Support 50
The frame 600 is sequentially attached between the columns 500, such as 0, the frame 600, and the column 500. Frame 6 on the pillar 500
28 is a perspective plan view showing a state where 00 is fixed. As shown in FIG. 28, both of the two frames 600 attached to the same column 500 may be attached to the same column hole 511 provided in the column 500 (FIG. 2).
See 8 (A). ), And may be attached to different column holes 511 (see FIG. 28B). The former mounting method is possible with the bolt 680 in this embodiment.
This is because the length of the threaded portion 682 is longer than the length of the frame hole 611 and shorter than the length of the frame hole 611 plus the length of the support hole 511. The post-change of the mounting position of the frame 600 with respect to the support column 500 can be easily performed only by removing the bolt 680 and then performing the above-described processing.
