Description

The present invention relates to a hinge device that rotatably connects a second object such as a door to a first object such as a housing.

For example, in a game machine such as a pachislot machine, a door is rotatably attached to a side edge of an opening of a housing via a hinge device. The door is closed and tilted slightly upwards. Therefore, torque acts on the opened door in the direction of naturally closing due to its own weight.
When maintaining the machinery inside the housing, it is necessary to keep the door open. If the door is opened 90 degrees or more, the torque in the closing direction does not work on the door, but if it does so, it will interfere with the user of the next game machine.

In the hinge device for a game machine of Patent Document 1, a friction mechanism is provided between two constituent members that are relatively displaced when the door is opened and closed. When the door is opened by less than 90 degrees and tries to be closed by its own weight, the frictional resistance of the friction mechanism regulates the relative displacement between the constituent members, thereby maintaining the door at a desired opening angle.

In the hinge device of Patent Document 2, a washer and a leaf spring are attached to a shaft member that rotatably connects the connecting plate portions of the two constituent members. By urging the connecting plate portion of one constituent member toward the connecting plate portion of the other constituent member by a leaf spring, frictional resistance is generated between the connecting plate portions of the constituent members via a washer, which causes the constituent member. The relative rotation between them is regulated, and thus the rotation of the door is regulated.

The mounting cylinder 44 has a locking portion 44a having a diameter larger than that of the cylinder portion at one end, and by crimping the other end portion in the above-mentioned mounting state to form a locking portion 44b having a diameter larger than that of the cylinder portion. The mounting work of the friction mechanism 40 is completed.
The leaf spring 43 is compressed by the caulking of the other end of the mounting cylinder 44, and the outer friction plate 41A is locked to the locking portion 44b by the elastic force of the leaf spring 43 and toward the side plate portion 31b. It is urged, and the inner friction plate 41B is urged in a direction away from the side plate portion 31b and is locked to the locking portion 44a.
As a result, frictional resistance is generated between the outer friction plate 41A and the side plate portion 31b of the first link 31 via the friction washer 42A, and a friction washer is generated between the inner friction plate 41B and the side plate portion 31b. Friction resistance is generated via the 42B and the leaf spring 43.

The friction plates 41A and 42A are made of stainless steel, and the friction washers 42A and 42B are made of a material having excellent wear resistance such as phosphor bronze.

As shown in FIGS. 7 (C) and 9, the outer friction washer 42A is formed by fitting the engaging hole 42y into the engaging convex portion 31y formed on the outer surface of the side plate portion 31b of the first link 31. Rotation is prohibited with respect to the first link 31.
As shown in FIG. 7B, the inner friction washer 42B is prohibited from rotating with respect to the first link 31 by fitting the notch 42z into the end edge of the main plate portion 31a of the first link 31. There is.

As shown in FIGS. 10 to 13, the shaft member 36 is passed through the bearing holes 23x and 24x formed in the extending portions 23 and 24 of the second hinge main body 20, and is formed in the side plate portion 31c of the first link. The first link 31 of the link assembly LA is rotatably connected to the second hinge body 20 by passing it through the bearing hole 31x'and through the mounting cylinder 44 of the friction mechanism 40.

The shaft member 38 (regulating portion) for rotatably connecting the second link 32 to the extending portions 23 and 24 of the second hinge main body 20 penetrates the bearing holes 23y and 24y of the extending portions 23 and 24. , Not only penetrates the bearing hole of the second link 32, but also penetrates the sub-insertion holes 41y of the friction plates 41A and 41B of the friction mechanism 40. As a result, the friction plates 41A and 41B are prohibited from rotating with respect to the second hinge main body 20 (displacement in the axial direction is possible).

The hinge device 3 of the present embodiment further includes a pair of spacers 51 and 52. These spacers 51 and 52 are made of a resin such as polyacetal having low frictional resistance.
One spacer 51 is arranged between the side plate portion 31b of the first link and the extending portion 23 of the second hinge main body 20. The spacer 51 is formed with a hole 51x for accommodating the locking portion 44b of the mounting cylinder 44 and for inserting the shaft member 36, and a recess 51a for accommodating the friction plate 41A. Further, the spacer 51 is formed with an insertion hole 51y for inserting the shaft member 38.
The other spacer 52 is arranged between the side plate portion 31c of the first link and the extending portion 24 of the second hinge main body 20, and makes direct frictional contact between these side plate portions 31c and the connecting plate portion 24. Forbidden. Insertion holes 52x, 52y through which the shaft members 36, 38 are inserted are formed in the spacer 52.

In the hinge device 3 having the above configuration, the frictional resistance torque with respect to the door 2 is generated by the friction mechanism 40. That is, as the door 2 rotates, the first link 31 and the second link 32 rotate with respect to the first hinge body 10, and the second hinge body 20 rotates with respect to the first link 31 and the second link 32. To do. When the first link 31 and the second hinge main body 20 rotate relative to each other, the friction plates 41A and 41B held in a state where the rotation is prohibited by the second hinge main body 20 and the side plate portion 31b of the first link 31. Relative rotation occurs between the two, and frictional resistance between the friction plates 41A and 41B and the side plate portion 31b of the first link 31 causes a resistance torque between the first link 31 and the second hinge body 20. As a result, a resistance torque is generated in the door 2.

When the opening angle of the door 2 is small, for example, less than 18 °, the natural rotation torque due to the weight of the door 2 is larger than the resistance torque due to the friction mechanism 40, so that the door 2 naturally rotates in the closing direction. , Can be closed tightly.
Within the rotatable range of the door 2, for example, in the range of 18 ° or more and less than 90 °, the rotational torque due to the weight of the door 2 becomes smaller than the resistance torque due to the friction. As a result, the door 2 can be prevented from closing naturally, and the inside of the game machine M can be maintained, for example, in an open state of about 60 °.

In the present embodiment, since the first link 31, which is the main component of the hinge device 3, is used to generate the frictional resistance, the configuration of the friction mechanism 40 can be simplified and the cost can be suppressed.
Further, the friction plates 41A and 41B, the friction washers 42A and 42B, and the leaf spring 43 of the friction mechanism 40 are attached to the side plate portion 31b of the first link 31 in advance via the mounting cylinder 44 to form the link assembly LA. This can be done, and since the link assembly LA is assembled to the second hinge main body 20 by the shaft member 36, the assembly workability can be improved.

The leaf spring 43 generates frictional resistance torque by urging the friction plates 41A and 41B in the axial direction, and it is not necessary to urge the constituent members of the hinge device 3, so that the load on the leaf spring 43 is reduced. It is possible to obtain frictional resistance efficiently.

Since the friction washers 42A and 42B made of an abrasion-resistant material are interposed between the side plate portions 31b of the first link 31 and the friction plates 41A and 41B, the durability can be improved. Further, since the friction washers 42A and 42B are prohibited from rotating with respect to the first link 31, frictional resistance can be reliably generated.
The friction washers 42A and 42B may be rotatable with respect to the first link 31. Further, the friction washers 42A and 42B may be omitted.

In the present embodiment, since the friction plates 41A and 41B are arranged on both sides of the side plate portion 31b of the first link 31, frictional resistance can be generated more efficiently. One of the friction plates 41A and 41B may be omitted.

In the present embodiment, the regulation that prohibits the rotation of the friction plates 41A and 41B by using the shaft member 38 that rotatably connects the second link 32 to the second hinge main body 20 with the sub portion 41a of the friction plates 41A and 41B. Since it is a part, the configuration can be simplified.
The restricting portion is composed of an engaging convex portion protruding from the extending portion of the second hinge main body, and the engaging convex portion is inserted into the insertion hole 41y formed in the sub portion 41a of the friction plates 41A and 41B.
