Description

【０００１】
【発明の属する技術分野】
本発明は、パチンコ遊技機などの遊技機に使用される保護カバーなどの開閉部材（ウイング）を、機構板等の固定部に対し開閉可能に支持する開閉部材のヒンジ構造に関する。
【０００２】
【従来の技術】
パチンコ遊技機などの遊技機内には、液晶ディスプレイ、各種の電動機器、それらを制御する回路基板など多くの機器や電気部品が装着され、それらの電気部品や機器を保護するために、通常、遊技機の背面側には、保護カバーが取り付けられている。
【０００３】
【発明が解決しようとする課題】
従来の遊技機に装着されるこの種の保護カバーは、合成樹脂により形成され、例えばその周縁部に嵌合部を形成すると共に、固定部となる機構板などに対応する嵌合部を設け、それらの嵌合部を嵌合させて、保護カバーを取り付けていた。
【０００４】
このため、保守点検などの際に、保護カバーを開く場合には、保護カバーを取り外して作業することになり、保護カバーの置き場所に苦慮するという問題があった。
【０００５】
そこで、遊技機の保護カバーを、ヒンジを介して機構板などの被固定部に開閉可能に取り付けることが検討されたが、保護カバーは着脱を必要とするため、ヒンジとしては着脱式のヒンジを使用する必要があり、また、着脱式のヒンジを保護カバーとは別個に製作して固定する場合は、ヒンジの構造が複雑化し、部品点数の増大を伴うと共に、組付けの作業工数が増加するなどの問題があった。
【０００６】
本発明は、上述の課題を解決するものであり、開閉部材を固定部に対し着脱可能に且つ開閉可能に、簡単に取り付けることができる遊技機用開閉部材のヒンジ構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、本発明の遊技機用開閉部材のヒンジ構造は、遊技機用の開閉部材を固定部に対し着脱可能に且つ開閉可能に装着するためのヒンジ構造であって、固定部には軸保持部が開口部を有して形成され、開閉部材の縁部には軸保持部に開口部を通して回動可能に嵌合される軸部が形成され、開閉部材には軸部に隣接して軸部と同軸上に支持軸部が形成され、固定部には軸保持部に隣接してばね弾性保持部が支持軸部を回動可能に弾性支持するように設けられ、ばね弾性保持部は、自由端を有した先端部寄りが該固定部側に僅かに曲げられると共に、弾性変形可能な板状に形成され、且つ軸部が軸保持部の内側に押し付けられるように支持軸部を付勢して装着され、軸保持部は、先端に半円弧状の係止曲げ部を有すると共に、係止曲げ部の下側に開口部を設けて形成され、軸部と支持軸部は開閉部材と共に合成樹脂により一体成形され、軸保持部とばね弾性保持部は固定部と共に合成樹脂により一体成形され、支持軸部をばね弾性保持部の上面に当接させて滑らせながら、軸部を軸保持部に嵌め込んで開閉部材が固定部に組み付けられ、ばね弾性保持部を固定部側に押さえながら、軸部を内側に移動させて、軸保持部の係止曲げ部から軸部を外すことにより、開閉部材が該固定部から外されることを特徴とする。
【０００９】
【作用】
上記構成のヒンジ構造は、開閉部材を固定部に対し開閉可能に装着する場合、開閉部材を持って、その支持軸部をばね弾性保持部の上面に当接させて滑らせながら、軸部を軸保持部に嵌め込む。このとき、軸保持部の係止曲げ部は半円弧状で、下側に開口部が形成されているため、軸部を容易に軸保持部に嵌め込むことができる。
【００１０】
そして、軸部を軸保持部に嵌め込んだ状態では、ばね弾性保持部が支持軸部を、軸部を軸保持部の係止曲げ部に押し付ける側に付勢するから、軸部が軸保持部から容易に外れることは防止される。
【００１１】
このようなヒンジを介して装着された開閉部材は、開閉される際、軸部が軸保持部の係止曲げ部の内周面で円滑に摺動可能に保持されるから、固定部に対し円滑に開閉することができる。
【００１２】
一方、開閉部材を外す場合は、ばね弾性保持部を押さえて、軸保持部に軸部を押し付ける付勢力を解除し、軸部を開口部側に移動させれば、軸保持部から軸部を外して、ヒンジから開閉部材を取り外すことができる。
【００１３】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。図１はパチンコ遊技機の前面枠の内側に取り付けられる固定部としての機構板１の斜視図を示し、機構板１の略中央の開口部には、向かって左側に開放される保護カバー２の縁部がヒンジ３を介して開閉可能に装着されている。このヒンジ３は、保護カバー２を着脱可能に且つ開閉可能に支持する分離可能なヒンジとして形成され、同じ構造のヒンジ３が上部と下部に設けられる。
【００１４】
ヒンジ３は、図２の部分正面図に示すように、機構板１に設けた軸保持部１０と、保護カバー２の縁部に設けられ、軸保持部１０に回動可能に嵌合保持される軸部１５と、機構板１に設けたばね弾性保持部１１と、保護カバー２の縁部に設けられ、ばね弾性保持部１１によりばね弾性を持って保持される支持軸部１６とから構成される。
【００１５】
図３の断面図に示すように、機構板１の軸保持部１０は、その機構板１における保護カバー２が取り付けられる取付面上に、先端に係止曲げ部１２を設けて突設される。その係止曲げ部１２は、装着される保護カバー２の内側に向けて半円弧状に曲げられ、その係止曲げ部１２の下側半分に、つまり取付面側に開口部１３が設けられている。係止曲げ部１２の内側は滑らかな半円筒状の内周面が形成され、軸部１５が円滑に回動するようにしている。
【００１６】
この軸保持部１０を平面または底面から見た場合、係止曲げ部１２は半円弧形のフック状にその先端を曲げた形状に形成されている。また、軸保持部１０の元部には、補強用の三角形リブ１４が軸保持部１０の平面と直角方向に機構板１の取付面から立設され、充分な補強を行なって、保護カバーの荷重を軸保持部１０で保持する構造としている。
【００１７】
さらに、機構板１には、上記軸保持部１０の下側に、ばね弾性保持部１１が舌状に設けられる。図４に示すように、この舌状のばね弾性保持部１１は、自由端を有した板状に形成され、機構板１上の元部から保護カバーの内側に向けて自由端を突き出し、ばね弾性をもって自由端側を変形可能に形成される。このばね弾性保持部１１は、保護カバー２側に設けた後述の支持軸部１６を背面側から保持して、上記軸保持部１０の係止曲げ部１２側に、つまり機構板１の前面側にばね弾性力を持って押すように形成される。また、ばね弾性保持部１１の先端部寄りは、内側に少し曲がって形成され、保護カバー２の支持軸部１６を係合し易くしている。
【００１８】
保護カバー２側には、軸部１５の下側に且つ軸部１５と同軸位置に、支持軸部１６が突設される。この支持軸部１６は、機構板１側のばね弾性保持部１１から付勢力を機構板１の上面側に受けて保護カバー２の脱落を防止するために設けられる。また、図４に示すように、この支持軸部１６と保護カバー２との間には、板部１７が空間を埋めるように形成され、支持軸部１６を強固に保持している。
【００１９】
保護カバー２を着脱可能に且つ開閉可能に保持するためには、少なくとも一方の側（ここでは内側）からばね弾性力で軸部１５を付勢する必要があるが、軸保持部１０の内側から軸部１５をばね弾性力で保持する部材を設けることは、機構板１の成形上、型抜きなどの問題から大きな困難性が伴う。
【００２０】
このために、上記のように、軸部１５を保持する軸保持部１０の反対側（内側から外側）に付勢力を生じさせるばね弾性保持部１１を機構板１の軸保持部１０の下側位置に設け、保護カバー２側には、軸部１５の下側に軸部１５と同軸上に支持軸部１６を設け、軸部１５を内側から外側に保持する付勢力は、その下側に設けたばね弾性保持部１１から保護カバー２側の支持軸部１６に付与する構造としている。これにより、機構板１と軸保持部１０及びばね弾性保持部１１を合成樹脂の射出成形により容易に一体成形することができる。また、保護カバー２と軸部１５及び支持軸部１６も合成樹脂の射出成形により容易に一体成形することができる。
【００２１】
このように、軸保持部１０及びばね弾性保持部１１は機構板１を合成樹脂により成形する際、一体成形され、また、軸部１５及び支持軸部１６は保護カバー２を合成樹脂により成形する際、一体成形される。そして、機構板１に対し保護カバー２を装着する場合は、図６、図７に示すように、保護カバー２を持って、その上部と下部の支持軸部１６をばね弾性保持部１１の上面に当接させて滑らせながら、上部と下部の軸部１５を機構板１の軸保持部１０に嵌め込む。このとき、軸保持部１０の係止曲げ部１２は半円弧状で、下側に開口部１３が形成されているため、軸部１５を容易に軸保持部１０に嵌め込むことができる。
【００２２】
そして、図１、図３、図４のように、軸部１５を軸保持部１０に嵌め込んだ状態では、ばね弾性保持部１１が支持軸部１６を、軸部１５を軸保持部１０の係止曲げ部１２に押し付ける側に付勢するから、軸部１５が軸保持部１０から容易に外れることは防止される。このようなヒンジ３を介して装着された保護カバー２は、開閉される際、軸部１５が軸保持部１０の係止曲げ部１２の内周面で円滑に摺動可能に保持されるから、機構板１に対し円滑に開閉することができる。
【００２３】
一方、保護カバー２を機構板１から外す場合は、保護カバー２を約９０度程度開いた状態で、ばね弾性保持部１１の先端を内側に押さえながら、軸部１５を内側に移動させて、軸保持部１０の係止曲げ部１２から軸部１５を外し、そのまま保護カバー２を右側にずらすように動かせば、軸部１５が軸保持部１０から外れ、比較的容易に保護カバー２をヒンジ３から外すことができる。
【００２４】
このように、機構板１の中央の開口部を覆う保護カバー２が、ヒンジ３を介して開閉に装着されるため、従来の保護カバーのように、パチンコ遊技機の保守点検の際に外さずに、開放するだけで点検作業を行なうことができる。また、ヒンジ３は、上記のように、ばね弾性保持部１１を押さえながら軸部１５を左側に引けば、固定部に対し可動部を容易に取り外すことができ、また同様に、取り外した保護カバー２の軸部１５を軸保持部１０に嵌め込み、保護カバー２を容易に装着することができる。また、このヒンジ３は、合成樹脂製の機構板１と合成樹脂製の保護カバー２を各々成形する際に、一体成形されるから、別部品のヒンジを取り付ける場合より、部品点数を低減でき、別部品のヒンジを機構板や保護カバーに固定する工数を削減することができる。
【００２５】
なお、上記実施形態では、機構板１に保護カバー２を開閉可能に装着するヒンジについて説明したが、その他の開閉部材を固定部に対し開閉可能に装着する際に、上記構成のヒンジを適用することもできる。
【００２６】
【発明の効果】
以上説明したように、本発明の遊技機用開閉部材のヒンジ構造によれば、固定部には軸保持部が開口部を有して形成され、開閉部材の縁部には軸保持部に開口部を通して回動可能に嵌合される軸部が形成され、開閉部材には軸部に隣接して軸部と同軸上に支持軸部が形成され、固定部には軸保持部に隣接してばね弾性保持部が支持軸部を回動可能に弾性支持するように設けられたから、支持軸部によりばね弾性保持部を押さえながら、軸部を開口部から軸保持部に嵌め込むようにすれば、簡単に開閉部材を固定部に対し開閉可能に且つ着脱可能に装着することができる。また、軸部と支持軸部を開閉部材と共に合成樹脂により一体成形し、軸保持部とばね弾性保持部を固定部と共に合成樹脂により一体成形すれば、部品点数が少なくなり、別部品のヒンジを開閉部材や固定部に取り付けるための作業工数を削減することができる。

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a mechanism plate 1 as a fixing portion attached to the inside of a front frame of a pachinko gaming machine. A protective cover 2 opened to the left side toward the substantially central opening of the mechanism plate 1 is shown. An edge portion is mounted via a hinge 3 so as to be openable and closable. The hinge 3 is formed as a separable hinge that supports the protective cover 2 so as to be detachable and openable and closable, and the hinge 3 having the same structure is provided at the upper part and the lower part.
[0014]
As shown in the partial front view of FIG. 2, the hinge 3 is provided on the shaft holding portion 10 provided on the mechanism plate 1 and the edge of the protective cover 2, and is rotatably fitted and held on the shaft holding portion 10. And a support elastic part 11 provided at the edge of the protective cover 2 and held by the spring elastic holding part 11 with spring elasticity. The
[0015]
As shown in the cross-sectional view of FIG. 3, the shaft holding portion 10 of the mechanism plate 1 is provided on the attachment surface to which the protective cover 2 of the mechanism plate 1 is attached, with a locking bent portion 12 provided at the tip. . The locking bent portion 12 is bent in a semicircular arc shape toward the inner side of the protective cover 2 to be mounted, and an opening 13 is provided in the lower half of the locking bent portion 12, that is, on the mounting surface side. Yes. A smooth semi-cylindrical inner peripheral surface is formed on the inner side of the locking bent portion 12 so that the shaft portion 15 can smoothly rotate.
[0016]
When the shaft holding part 10 is viewed from the plane or the bottom, the locking bent part 12 is formed in a semicircular hook shape with its tip bent. Further, a reinforcing triangular rib 14 is erected from the mounting surface of the mechanism plate 1 in a direction perpendicular to the plane of the shaft holding portion 10 at the base portion of the shaft holding portion 10 so as to sufficiently reinforce the protective cover. The load is held by the shaft holder 10.
[0017]
Further, the mechanism plate 1 is provided with a spring elastic holding portion 11 in a tongue shape below the shaft holding portion 10. As shown in FIG. 4, the tongue-shaped spring elastic holding portion 11 is formed in a plate shape having a free end, protrudes from the base portion on the mechanism plate 1 toward the inside of the protective cover, and The free end side is deformable with elasticity. The spring elastic holding portion 11 holds a support shaft portion 16, which will be described later, provided on the protective cover 2 side from the back side, and on the side of the locking bending portion 12 of the shaft holding portion 10, that is, the front side of the mechanism plate 1. It is formed so as to be pushed with a spring elastic force. Further, the end of the spring elastic holding portion 11 is bent slightly inward so that the support shaft portion 16 of the protective cover 2 can be easily engaged.
[0018]
On the side of the protective cover 2, a support shaft portion 16 protrudes below the shaft portion 15 and at a position coaxial with the shaft portion 15. The support shaft portion 16 is provided to receive a biasing force from the spring elastic holding portion 11 on the mechanism plate 1 side to the upper surface side of the mechanism plate 1 to prevent the protective cover 2 from falling off. Further, as shown in FIG. 4, a plate portion 17 is formed between the support shaft portion 16 and the protective cover 2 so as to fill the space, and the support shaft portion 16 is firmly held.
[0019]
In order to hold the protective cover 2 so as to be detachable and openable / closable, it is necessary to urge the shaft portion 15 with spring elastic force from at least one side (inner side here). Providing a member that holds the shaft portion 15 with a spring elastic force is accompanied by great difficulty in terms of molding the mechanism plate 1 due to problems such as die cutting.
[0020]
For this reason, as described above, the spring elastic holding portion 11 that generates a biasing force on the opposite side (from the inside to the outside) of the shaft holding portion 10 that holds the shaft portion 15 is provided below the shaft holding portion 10 of the mechanism plate 1. The supporting shaft 16 is provided coaxially with the shaft 15 on the lower side of the shaft 15 on the protective cover 2 side, and the urging force for holding the shaft 15 from the inside to the outside is on the lower side. The spring elastic holding portion 11 is provided to the support shaft portion 16 on the protective cover 2 side. Thereby, the mechanism board 1, the shaft holding part 10, and the spring elastic holding part 11 can be easily integrally formed by injection molding of synthetic resin. Further, the protective cover 2, the shaft portion 15, and the support shaft portion 16 can be easily integrally formed by injection molding of synthetic resin.
[0021]
As described above, the shaft holding portion 10 and the spring elastic holding portion 11 are integrally formed when the mechanism plate 1 is formed of synthetic resin, and the shaft portion 15 and the support shaft portion 16 are formed of the protective cover 2 using synthetic resin. In this case, it is integrally formed. When the protective cover 2 is attached to the mechanism plate 1, as shown in FIGS. 6 and 7, the protective cover 2 is held and the upper and lower support shaft portions 16 are connected to the upper surface of the spring elastic holding portion 11. The upper and lower shaft portions 15 are fitted into the shaft holding portion 10 of the mechanism plate 1 while sliding in contact with each other. At this time, the locking bent portion 12 of the shaft holding portion 10 has a semicircular arc shape, and the opening portion 13 is formed on the lower side. Therefore, the shaft portion 15 can be easily fitted into the shaft holding portion 10.
[0022]
1, 3, and 4, when the shaft portion 15 is fitted into the shaft holding portion 10, the spring elastic holding portion 11 serves as the support shaft portion 16, and the shaft portion 15 serves as the shaft holding portion 10. The shaft 15 is prevented from being easily detached from the shaft holding portion 10 because it is biased toward the side pressed against the locking bent portion 12. When the protective cover 2 mounted via the hinge 3 is opened and closed, the shaft portion 15 is held so as to be smoothly slidable on the inner peripheral surface of the locking bent portion 12 of the shaft holding portion 10. The mechanism plate 1 can be opened and closed smoothly.
[0023]
On the other hand, when removing the protective cover 2 from the mechanism plate 1, with the protective cover 2 opened about 90 degrees, the shaft portion 15 is moved inward while pressing the tip of the spring elastic holding portion 11 inward. If the shaft portion 15 is removed from the locking bent portion 12 of the shaft holding portion 10 and the protective cover 2 is moved to the right as it is, the shaft portion 15 is detached from the shaft holding portion 10 and the protective cover 2 is hinged relatively easily. 3 can be removed.
[0024]
Thus, since the protective cover 2 covering the central opening of the mechanism plate 1 is attached to be opened and closed via the hinge 3, it is not removed during maintenance and inspection of the pachinko gaming machine like the conventional protective cover. In addition, inspection work can be performed simply by opening. Further, as described above, the hinge 3 can easily remove the movable part from the fixed part by pulling the shaft part 15 to the left while holding the spring elastic holding part 11, and similarly, the removed protective cover. The protective cover 2 can be easily mounted by fitting the two shaft portions 15 into the shaft holding portion 10. In addition, since the hinge 3 is integrally formed when the synthetic resin mechanism plate 1 and the synthetic resin protective cover 2 are respectively molded, the number of parts can be reduced as compared with the case of attaching another hinge. It is possible to reduce the man-hours for fixing the hinges of separate parts to the mechanism plate and the protective cover.
[0025]
In the above embodiment, the hinge for attaching the protective cover 2 to the mechanism plate 1 so as to be opened and closed has been described. However, when other opening and closing members are attached to the fixed portion so as to be opened and closed, the hinge having the above configuration is applied. You can also.
[0026]
【The invention's effect】
As described above, according to the hinge structure of the opening / closing member for gaming machines of the present invention, the fixed portion is formed with the shaft holding portion having the opening, and the edge of the opening / closing member is opened to the shaft holding portion. A shaft portion that is rotatably fitted through the portion is formed, a support shaft portion is formed coaxially with the shaft portion adjacent to the shaft portion on the opening / closing member, and a shaft holding portion is adjacent to the fixed portion Since the spring elastic holding portion is provided so as to elastically support the support shaft portion so as to be rotatable, the shaft portion is fitted into the shaft holding portion from the opening while holding the spring elastic holding portion by the support shaft portion. The opening / closing member can be easily attached / detached to / from the fixed portion. Also, if the shaft part and the support shaft part are integrally formed with synthetic resin together with the opening and closing member, and the shaft holding part and the spring elastic holding part are integrally formed with synthetic resin together with the fixing part, the number of parts can be reduced, and the hinge of another part can be reduced. The number of work steps for attaching to the opening / closing member and the fixed portion can be reduced.
