Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable hinge (pin insertion type in which a pin is inserted into a bearing hole) for supporting a door with respect to a main body so that the door can be opened and closed. In particular, the opening degree of the door is stopped at a predetermined position. The present invention relates to a hinge provided with a door stopper.

[0002]

2. Description of the Related Art Conventionally, for example, as a hinge for supporting a door of a slot machine so as to be openable and closable, it is a hinge composed of a vertically long fixed member and a movable member, which are provided at upper and lower edges of a mounting plate portion of the fixed member. , Bearing portions each having a bearing hole are provided with their axial center positions aligned on one axis, and on the winding portions formed on the upper and lower edges of the mounting plate portion of the movable member,
A detachable hinge is known in which each pin has its axial center aligned with one axial line and is fixed by projecting downward, and both pins are inserted and assembled in each bearing portion of the fixing member ( See, for example, JP-A-10-201922).

[0003]

In this hinge, a bearing hole serving as a bearing is provided on the upper and lower portions of a vertically long fixed member on the same axis, and a pin is provided on the upper and lower portions of a similar vertically movable member on the same axis. Since it is configured to be attached on the wire, for example, if the fixed member is fixed to the main body of the slot machine, the movable member is fixed to the front door, and the hinge is assembled so that the pin is inserted into the bearing hole, Even if the door is heavy, the door can be supported by the main body so that the door can be opened and closed smoothly and smoothly.

However, as in the case of the main body of a slot machine, when the front surface is inclined with respect to the vertical plane so that the lower portion of the front surface extends forward and the upper portion thereof pulls rearward, the door mounted on the front surface The rotation axis of the hinge is also inclined with respect to the vertical axis. For this reason, when the door is opened, a phenomenon occurs in which the door receives a force in the closing direction due to gravity and naturally closes when the opening is up to 90 degrees.

Therefore, when the slot machine is to be repaired or inspected, when it is desired to keep the door open, the work is performed with the door opened slightly beyond 90 degrees.
When some external force acts on the door and the opening degree of the door becomes 90 degrees or less, the door naturally closes, and there is a risk that the door may be closed carelessly during work.

The present invention has been made in view of the above points, and in a detachable hinge in which fixed side and movable side bearing portions and pins are fitted together and assembled, the door is opened at any preset opening. The purpose is to provide a hinge that can be kept stationary.

A hinge of the present invention for achieving the above object has a first member provided between a door that can be opened and closed and a main body and provided with a bearing member having a bearing hole, and a pin fitted in the bearing hole. In a detachable hinge comprising a second member provided with a shaft holding portion, a polygonal portion is provided on the outer circumference of a pin of the second member, and a clamping piece for clamping the polygonal portion of the pin with spring elasticity from both sides. And a door stopper having both sides is provided on the bearing member of the first member.

[0008]

According to the hinge constructed as described above, the first member is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, or vice versa. It is fixed as a member, and the first member is fixed to the main body as a fixed member for use. Further, for example, when the first member of the hinge is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, the pin provided on the winding part of the second member is fixed upward and the pin thereof is fixed. The bearing member of the first member is fitted in from above, the hinge is assembled, and the door is attached to the main body via the hinge so as to be openable and closable. On the other hand, when the first member of the hinge is fixed to the main body as the fixed member and the second member is fixed to the door as the movable member, the pin provided on the winding portion of the second member is arranged downward and The pin of the member is fitted into the bearing hole of the bearing member of the first member from above, and the hinge is assembled.

For example, when the door stopper is provided on the bearing member of the first member on the door side and the polygonal portion is provided on the outer periphery of the pin of the second member on the main body side, the pair of sandwiching pieces of the door stopper are Is arranged so as to sandwich the polygonal part of the elastic member from both sides with spring elasticity. When the door closed with respect to the main body is opened, the polygonal part of the pin on the fixed side is clamped by the pinching piece of the door stopper provided on the bearing member of the first member on the movable side with spring elasticity. Will rotate against the frictional resistance caused by the sandwiching of the pin and the polygonal portion of the pin.

Therefore, when the operating force for opening the door is stopped, the first member having the bearing member and the door stopper stops at the position where the holding piece of the door stopper abuts on the flat portion of the polygonal portion of the pin. The door then stops at that position. For example, when the polygonal portion is a regular octagon, the first member of the movable member of the hinge, that is, the door has an opening angle of 45 °, 90 °, 135 °, and 180 °, and the flat portion on the outer periphery of the pin is the holding piece of the door stopper. It will be clamped by and will be in a stable holding state, and the door will stop.

Therefore, even if the door is naturally closed due to gravity or the like, the door is stopped by the door stopper and held at a predetermined opening angle. When opening or closing the door from that state, when the door is held and rotated, the holding piece of the door stopper of the first member is elastically deformed, and the engagement position with the polygonal portion of the pin is relatively. The door moves as it moves, overcoming the polygonal portion of the pin.

Therefore, as in the slot machine, the door is attached to the front surface of the inclined main body, and even if the opened door tries to close due to gravity, the polygonal portion on the outer periphery of the pin and the door stopper on the bearing member side. By the holding operation of the holding piece, the door is held at the opening angle, and the door is prevented from being closed carelessly.

The upper and lower pins 13b and 14b are attached to positions corresponding to the bearing holes 3b and 4b of the bearing members 3 and 4 of the movable member 1, that is, predetermined positions in which the axial center positions are aligned.

The hinge constructed in this manner is shown in FIGS.
As shown in FIG. 1, the fixing member 11 has a main body (cabinet) 1 of a game machine such as a slot machine whose front surface is inclined.
It is fixed by inserting a mounting screw into the mounting hole of the mounting plate portion 12 on the 8 side and tightening. In addition, the movable member 1
Is attached to the position corresponding to the fixing member 11 on the front door 19 side of the game machine by tightening the base frame body 2 with the attaching screw. As shown in FIG. 8, the fixing member 11 includes a main body 18
Is formed to have a length substantially equal to the length of the vertical side of the opening of the main body 1
It is attached over substantially the entire inner vertical side of 8. Also,
The movable member 1 is formed to have substantially the same length as the inner vertical side of the front door 19, and is attached to the edge of the inner vertical side of the front door 19.

Then, as shown in FIG. 7, with the front door 19 opened, the upper and lower bearing portions 3a and 4a of the hinge movable member 1 are fitted to the upper and lower pins 13b and 14b of the fixed member 11,
The front door 19 is attached to the main body 18. At this time, the front door 19
First, the upper and lower bearing members 3 and 4 are aligned with the shaft holding portions 13 and 14 on the fixed member 11 side, and the guide portions 5 and 6 in the bearing members 3 and 4 are fixed to the shaft holding portions 13 and 14 on the fixed member side. The box-shaped bearing member 3, so as to hit the winding parts 13a, 14a of the
The front door 19 is moved so as to cover the shaft holding portions 13 and 14.

At this time, when the upper and lower guide portions 5 and 6 hit the upper and lower winding portions 13a and 14a, and the front door 19 is further pushed in, the inclined guide surfaces of the guide portions 5 and 6 cause the winding portion. 13a, 14a, that is, pins 13b, 14b
Are guided and reach the axial positions of the bearing holes 3b and 4b. Therefore, in this state, as shown in FIG. 6, if the position of the front door 19 is slightly lowered, the pins 13b and 14b automatically enter into the bearing holes 3b and 4b and are fitted therein. As a result, the pins 13b and 14b of the upper and lower shaft holding portions 13 and 14 are fitted into the bearing holes 3b and 4b of the bearing members 3 and 4, and the hinge movable member 1 is inserted.
Assembling of the fixing member 11 can be completed easily.

At this time, the front door 19 is in an open state of about 90 degrees, and the door stoppers 7 and 8 mounted on the bearing members 3 and 4 of the hinge fixed member 11 side are movable as shown in FIG. The pins 13b and 14b of the shaft holding portions 13 and 14 on the member 1 side are in a state of sandwiching the polygonal portions 13c and 14c, and the sandwiching pieces 7a and 8a on both sides of the polygonal portions 13c and 14c spring the flat portions of the polygonal portions 13c and 14c. It is in the state of being sandwiched by and it causes a large friction resistance. Therefore, the pin 13 on the fixed member 1 side is locked by the door stoppers 7, 8 on the movable member 1 side.
b and 14b are clamped, the front door 19 holds the open state,
Natural closure is prevented.

In this state, when the front door 19 is held and rotated in a closing direction, the front door 19 is hinged to the pins 13b and 14 of the hinge.
Although it rotates about b as an axis, at this time, since the pinching pieces 7a and 8a of the door stoppers 7 and 8 pinch the pin with spring elasticity, the door is held by the polygonal portions 13c and 14c of the pin and the pinching piece. It will rotate against the frictional resistance generated by sandwiching 7a and 8a.

Therefore, when the operation force for opening the front door 19 is stopped, the holding pieces 7a, 8a of the door stoppers 7, 8 come into contact with the flat portions of the polygonal portions 13c, 14c of the pins 13b, 14b. At the position, the movable member 1 having the bearing members 3 and 4 and the door stoppers 7 and 8 stops due to the increase of the frictional resistance, and the front door 19 stops at that position. Here, since the polygonal portions 13c, 14c are regular octagons, the hinge movable member 1, that is, the front door 19 is 45 °, 90 °, 135 °, 18.
At the opening angle of 0 °, the flat portions of the outer circumferences of the pins 13b and 14b are clamped by the clamping pieces 7a and 8a of the door stoppers 7 and 8,
The stable holding state is established and the front door 19 is stopped.

Therefore, even when the door is naturally closed by gravity or the like, the front door 19 is stopped by the door stoppers 7 and 8 and is held at a predetermined opening angle. From that state, when opening or closing the front door 19,
When the movable member 1 is rotated, the holding pieces 7a, 8a of the door stopper of the movable member 1 are elastically deformed, and the polygonal portion 13c of the pin,
The engagement position with 14c relatively moves, the polygonal parts 13c and 14c of the pin are passed over, and the front door 19 rotates.

In this way, as in the slot machine, the front surface is inclined with respect to the vertical plane, and the hinge axis of the front door 19 is inclined with respect to the vertical axis. When the front door 19 is opened, Even if the door naturally closes due to gravity, the front door 19 can be stopped at a predetermined opening, and game machines can be repaired or inspected safely with the front door open. It can be carried out.

In the above embodiment, the polygonal portion is formed on the pin. However, as shown in FIG. 11, a plurality of engaging concave portions 33a are formed on the outer periphery of the pin 33 near the tip end at regular angular intervals (for example, 45 °). Spacing), and the engaging recess 33a of the pin 33 is formed.
It is also possible to provide on the bearing member side a door stopper 37 having engagement projections 37a on both sides for engaging the two with spring elasticity from both sides. In this case, the door stopper 37
The pair of engaging protrusions 37a having the spring elasticity is attached to the pin 3
3 engages with the engaging concave portion 33a and sandwiches it from both sides, whereby the frictional resistance at the time of relative rotation between the pin 33 and the bearing member increases, and when the front door is not opened or closed, The movable member, that is, the front door can be stopped at an angle of.

Furthermore, the hinge of the present invention is not limited to the above embodiment, but can be implemented in the following manners. For example, in the above, the movable member 1 side has the bearing holes 3b, 4b. The bearing members 3 and 4 are provided, and the fixing member 1
Shaft holding portions 13 and 14 having pins 13b and 14b on one side
However, conversely, the bearing member having the bearing hole may be fixed to the fixed member side and the shaft holding portion having the pin may be fixed to the movable member side. In that case, the pin on the movable member side faces downward. It is attached.
