Description

本発明は、パチンコ機、スロットマシン等のゲーム機の中枠（前面枠または前扉）を本体枠に対し開閉自在に取り付けるゲーム機用蝶番に関する。 The present invention relates to a hinge for a game machine in which an inner frame (front frame or front door) of a game machine such as a pachinko machine or a slot machine is attached to a main body frame so as to be freely opened and closed.

パチンコ機の中枠を本体枠に対し開閉自在に取り付ける蝶番として、従来、上部に取り付けられる上部蝶番と下部に取り付けられる下部蝶番からなる蝶番がある。この蝶番は、上部蝶番、下部蝶番共に固定部と可動部とに分かれて形成された分離型の蝶番であり、ピンと軸受部の嵌合により可動部側が固定部側に対し回動可能に支持される。つまり、上部蝶番の固定部は本体枠の上角部に固定され、上部蝶番の可動部は中枠の上角部に固定され、下部蝶番の固定部は本体枠の下角部に固定され、下部蝶番の可動部は中枠の下角部に固定される。そして、中枠を本体枠に対し取り付ける場合、中枠を持ってその下部蝶番の可動部を本体枠側の固定部にピンと軸受の嵌合により嵌め込み、同時に、その上部蝶番の可動部を本体枠側の固定部にピンと軸受の嵌合により嵌め込む。 Conventionally, there is a hinge comprising an upper hinge attached to the upper portion and a lower hinge attached to the lower portion as hinges for attaching the inner frame of the pachinko machine to the body frame so as to be freely opened and closed. This hinge is a separate hinge formed by dividing the upper and lower hinges into a fixed part and a movable part, and the movable part side is supported rotatably with respect to the fixed part side by fitting the pin and the bearing part. The That is, the fixed part of the upper hinge is fixed to the upper corner part of the main body frame, the movable part of the upper hinge is fixed to the upper corner part of the middle frame, and the fixed part of the lower hinge is fixed to the lower corner part of the main body frame. The movable part of the hinge is fixed to the lower corner of the middle frame. And when attaching the middle frame to the main body frame, hold the middle frame and fit the movable part of the lower hinge to the fixed part on the main body frame side by fitting the pin and bearing, and at the same time, move the movable part of the upper hinge to the main body frame Fit into the fixed part on the side by fitting the pin and bearing.

従って、上記のように、中枠を本体枠に対し装着する際には、上角部と下角部に設けた両蝶番のピンと軸受を上下同時に嵌め合わせて行なう必要があり、加えて、パチンコ機の中枠には、パチンコ球の打ち出し装置や玉出し装置等の制御駆動装置が数多く取り付けられているため、中枠の重量は非常に重い。また、これらの中枠は、パチンコホールにおいて、作業者の手作業により本体枠側に装着されるため、このような中枠の取り付け作業は、かなり難しく、労力を必要とし、ピンと軸受の嵌合が良好にできない場合には、蝶番や他の部材を傷つけてしまう問題があった。 Therefore, as described above, when the middle frame is attached to the main body frame, it is necessary to fit both the hinge pins provided on the upper corner portion and the lower corner portion and the bearing at the same time, and in addition, the pachinko machine Since many control drive devices such as a pachinko ball launching device and a balling device are attached to the inner frame, the weight of the inner frame is very heavy. In addition, since these inner frames are attached to the main body frame side in the pachinko hall by the operator's manual work, the installation work of such an inner frame is quite difficult and requires labor, and the pin and the bearing are fitted. In the case where this is not possible, there is a problem that the hinges and other members are damaged.

そこで、従来、下記特許文献１などにおいて、組付け作業を容易に行なうことができる分離型の蝶番が提案されている。
特開平８−２１５３９５号公報 Therefore, conventionally, a separate hinge that can be easily assembled has been proposed in Patent Document 1 below.
JP-A-8-215395

しかし、この従来の蝶番は、固定部の前部に突出した水平突出部上に、軸受孔を有する金属板を固定し、可動部上に上方に突設したピンを、その金属板を上方に弾性変形させながら、金属板の軸受孔に嵌入させる構造であるため、ゲーム機の使用中に、ドライバの先端などで金属板を押上げた場合、簡単に可動部のピンが固定部の軸受孔から外れ、中枠が不正に開放されてしまう虞があった。また、製造に際して、別部品として金属板が必要となり、固定部に金属板を取り付けるための作業工程を必要とするため、製造コストが高くなるという課題があった。 However, in this conventional hinge, a metal plate having a bearing hole is fixed on a horizontal projecting portion projecting from the front portion of the fixed portion, and a pin projecting upward on the movable portion is provided with the metal plate facing upward. Because it is a structure that fits into the bearing hole of the metal plate while elastically deforming, if the metal plate is pushed up with the tip of the driver etc. while using the game machine, the pin of the movable part can be easily There is a risk that the inner frame may be opened illegally.

A hinge for a game machine having a movable part attached to the upper corner of the front door of the game machine, wherein a bearing recess is formed inside the horizontal protrusion of the fixed part, and opens downwardly and circles around the front part. A large-diameter shaft portion that is formed in an arc shape and surrounded by a curved wall portion, protrudes downward at the center of the bearing recess in the horizontal protrusion, and fits into the bearing recess of the fixed portion. A protrusion is provided on the horizontal mounting portion, and a groove is formed on the upper surface of the large-diameter shaft portion so that the protrusion can be inserted from the center of the upper surface to the outside. passing There are formed, a large-diameter portion of the movable portion is introduced into the shaft receiving recess of the horizontal protrusion from the insertion opening, the projecting portion to the groove portion The large diameter shaft portion center is positioned the projecting portion of, and characterized in that rotatably fitting the large-diameter portion in the shaft receiving recess in the curved wall portion Te.

ここで、上記請求項１または２の蝶番においては、請求項３のように、ゲーム機の中枠の前面に開閉可能に取り付けられる透明板扉用の蝶番の軸を嵌入させるための軸受孔を、可動部の水平取付部に穿設することができる。 Here, in the hinge of claim 1 or 2, as in claim 3, there is provided a bearing hole for inserting a shaft of a hinge for a transparent plate door attached to the front face of the inner frame of the game machine so as to be opened and closed. It can be drilled in the horizontal mounting part of the movable part.

上記請求項１のゲーム機用蝶番は、ゲーム機の本体枠の上角部に蝶番の固定部が取り付けられ、中枠の上角部に蝶番の可動部が取り付けられる。また、本体枠の下角部と中枠の下角部には、ピンとそのピンを軸支する軸受部を有する下部蝶番の固定部と可動部が取り付けられる。 In the hinge for a game machine according to the first aspect, a hinge fixing portion is attached to the upper corner of the main body frame of the game machine, and a hinge movable portion is attached to the upper corner of the middle frame. Further, a fixed portion and a movable portion of a lower hinge having a pin and a bearing portion that pivotally supports the pin are attached to the lower corner portion and the lower corner portion of the main frame.

中枠を本体枠に対し装着する場合、先ず、中枠を持って下部蝶番の可動部を本体枠側の固定部に、ピンと軸受部との嵌合により嵌め込む。ピンと軸受部は可動部または固定部の何れかとなる場合がある。 When attaching the middle frame to the main body frame, first, the middle frame is held, and the movable portion of the lower hinge is fitted into the fixed portion on the main body frame side by fitting the pin and the bearing portion. The pin and the bearing portion may be either a movable portion or a fixed portion.

次に、中枠を開いた状態で、その下部蝶番を支点にして中枠を少し傾けながら、上部蝶番の可動部の水平取付部に設けた大径軸部を、固定部側の水平突出部の側部に設けた隣接開口部から内側に導入するように、中枠の可動部を固定部側に傾動させて動かす。このとき、可動部の水平取付部上の大径軸部は挿入開口部から水平突出部の内側に進入し、さらに、大径軸部の上面の溝部に、水平突出部内側の突部を通すようにガイドして、大径軸部を前方に移動させ、水平突出部の前部の軸受凹部内に嵌入させる。これにより、可動部側の大径軸部が固定部側の軸受凹部内に回動可能に嵌合され、中枠が本体枠に対し開閉可能に装着される。中枠は本体枠に対し所定の角度範囲で開閉可能とされるが、その回動角度範囲においては、突部が大径軸部の溝部に進入できず、突部が大径軸部の軸受凹部からの離脱を阻止し、中枠は開閉可能に保持され蝶番の組み付けが完了する。 Next, with the middle frame open, while tilting the middle frame a little with the lower hinge as a fulcrum, the large-diameter shaft provided on the horizontal mounting part of the movable part of the upper hinge is The movable part of the middle frame is tilted and moved to the fixed part side so as to be introduced into the inner side from the adjacent opening provided on the side part. At this time, the large-diameter shaft portion on the horizontal mounting portion of the movable portion enters the horizontal projecting portion from the insertion opening, and further passes the projecting portion inside the horizontal projecting portion into the groove portion on the upper surface of the large-diameter shaft portion. In this way, the large-diameter shaft portion is moved forward and fitted into the bearing recess in the front portion of the horizontal protrusion. As a result, the large-diameter shaft portion on the movable portion side is rotatably fitted in the bearing concave portion on the fixed portion side, and the middle frame is mounted so as to be openable and closable with respect to the main body frame. The middle frame can be opened and closed within a predetermined angle range with respect to the main body frame. However, in the rotation angle range, the protrusion cannot enter the groove portion of the large diameter shaft portion, and the protrusion is a bearing of the large diameter shaft portion. Detachment from the recess is prevented, and the middle frame is held openably and closably.

このように、上面に溝部を有した可動部側の大径軸部と、水平突出部の内側に設けた固定部側の軸受凹部と、の嵌合により、上部蝶番を組付けるため、従来のように、金属板が不要となり、部品点数を削減し、その取付のための作業工数を削減することができる。また、可動部の大径軸部が固定部の軸受凹部に回動可能に嵌合して可動部が支持されるため、蝶番の耐荷重性が増大し、可動部に大荷重がかかる場合でも、可動部を円滑に回動させ、中枠の開閉を円滑に行なうことができる。 In this way, the upper hinge is assembled by fitting the large-diameter shaft part on the movable part side having the groove part on the upper surface and the bearing concave part on the fixed part side provided inside the horizontal protruding part. Thus, a metal plate becomes unnecessary, the number of parts can be reduced, and the work man-hour for the attachment can be reduced. In addition, since the large-diameter shaft portion of the movable portion is rotatably fitted in the bearing recess of the fixed portion and the movable portion is supported, the load resistance of the hinge is increased, and even when a large load is applied to the movable portion. The movable part can be smoothly rotated, and the middle frame can be opened and closed smoothly.

さらに、可動部の大径軸部が固定部の水平突出部の軸受凹部に嵌入した状態では、水平突出部内の軸受凹部の外に位置する突部が大径軸部の離脱を阻止するため、所定の角度範囲内の中枠の開閉においては、特に中枠が閉鎖された状態においては、大径軸部が軸受凹部から外れることはなく、不正工具を差し込んで可動部を不正に外すなどの不正行為を防止することができる。 Furthermore, in the state where the large-diameter shaft portion of the movable portion is fitted in the bearing recess of the horizontal protrusion of the fixed portion, the protrusion located outside the bearing recess in the horizontal protrusion prevents the large-diameter shaft portion from being separated. When opening and closing the inner frame within a predetermined angle range, especially when the inner frame is closed, the large-diameter shaft portion does not come out of the bearing recess, and an unauthorized tool is inserted to remove the movable part illegally. Cheating can be prevented.

以下、本発明の実施の形態を図面に基づいて説明する。図１はパチンコ機などに使用されるゲーム機用蝶番の上部蝶番の平面図を示し、図２はその分解斜視図を示している。この上部蝶番は、本体枠側に固定される固定部１と中枠（前面枠）側の固定される可動部１０とから構成され、両部材は着脱可能に組み付けられる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an upper hinge of a game machine hinge used in a pachinko machine or the like, and FIG. 2 is an exploded perspective view thereof. The upper hinge is composed of a fixed portion 1 fixed to the main body frame side and a movable portion 10 fixed to the middle frame (front frame) side, and both members are detachably assembled.

固定部１は、鋼板を正面視でＬ字形に曲折して形成した取付板部２の水平部の前部に、水平突出部３を突設し、その水平突出部３の内側（下側）に、略円柱空間状の軸受凹部６が形成される。軸受凹部６は、水平突出部３の先端部が平面視で半円形になるように、曲面壁部４で周囲を囲って形成されている。つまり、先端部の１８０度（半円周部分）の範囲が曲面壁部４で囲まれ、水平突出部３の元部側には、その曲面壁部４に続いて軸受凹部６の直径を幅間隔とする直線状の壁部がガイド壁として元部に向けて両側に形成される。この直線状の外側の壁部は、取付板部２側に向けて延設されている。このような直線状の壁部と曲面壁部４とにより、水平突出部３の下側に略円柱空間状の軸受凹部６が形成され、この軸受凹部６の内部には、後述の可動部１０の円柱状の大径軸部１３が挿入され、回動可能に保持される。 The fixed portion 1 has a horizontal protrusion 3 protruding from the front of the horizontal portion of the mounting plate 2 formed by bending a steel plate into an L shape when viewed from the front, and the inner side (lower side) of the horizontal protrusion 3. In addition, a substantially cylindrical space-like bearing recess 6 is formed. The bearing recess 6 is formed so as to surround the periphery of the curved wall 4 so that the tip of the horizontal protrusion 3 is semicircular in plan view. That is, the range of 180 degrees (semicircular portion) of the tip is surrounded by the curved wall 4, and the diameter of the bearing recess 6 is increased to the base side of the horizontal protruding portion 3 following the curved wall 4. A linear wall portion as an interval is formed on both sides as a guide wall toward the base portion. The linear outer wall portion extends toward the mounting plate portion 2 side. The linear wall portion and the curved wall portion 4 form a substantially cylindrical space-like bearing recess 6 below the horizontal protrusion 3, and a movable portion 10 described later is formed inside the bearing recess 6. The cylindrical large-diameter shaft portion 13 is inserted and held rotatably.

さらに、水平突出部３の内側下面の軸受凹部６から外にシフトした位置に、突部５が下向きに突設されている。この突部５は、軸受凹部６に後述の可動部１０の円柱状の大径軸部１３が挿入されるとき、それをガイドし、挿入後は、大径軸部１３の外周部の外側に位置し、大径軸部１３の離脱を阻止するように作用する。また、この突部５は、水平突出部３の金属板を下側に切り起して形成することができるが、下側に絞り出して形成することもでき、或は水平突出部３に穿設した小孔に小ピンを突部５としてかしめ固定して形成することもできる。また、この突部５の外径と長さは、後述の大径軸部１３の上面に設けた溝部１３ａに進入可能な大きさとされる。なお、曲面壁部４の他方の直線状の壁部は、突部５の近傍位置で終了し、そこから水平突出部３の元部にかけての下側に、大径軸部１３を軸受凹部６に挿入するための挿入開口部７が壁部を除去した状態で開口して形成されている。 Further, a protrusion 5 is projected downward at a position shifted outward from the bearing recess 6 on the inner lower surface of the horizontal protrusion 3. The protrusion 5 guides the cylindrical concave portion 13 of the movable portion 10 to be described later into the bearing concave portion 6, and guides it when inserted into the outside of the outer peripheral portion of the large diameter shaft portion 13. It is located and acts to prevent the large-diameter shaft portion 13 from being detached. The protrusion 5 can be formed by cutting and raising the metal plate of the horizontal protrusion 3 downward, but can also be formed by squeezing downward or drilling in the horizontal protrusion 3. It is also possible to form a small pin by caulking and fixing it as a protrusion 5 in the small hole. Further, the outer diameter and the length of the protrusion 5 are set such that they can enter a groove portion 13a provided on the upper surface of a large-diameter shaft portion 13 which will be described later. Note that the other straight wall portion of the curved wall portion 4 ends at a position near the protrusion 5, and the large-diameter shaft portion 13 is placed on the lower side from the base portion of the horizontal protrusion 3 to the bearing recess 6. An insertion opening 7 is formed to be opened with the wall portion removed.

一方、可動部１０は、ゲーム機の中枠側に取り付けられる部材で、図２に示すように、本体部分として鋼板をＬ形に曲折して水平取付部１１と垂直取付部１２を形成し、その水平取付部１１上に上記固定部１の軸受凹部１３に嵌入される大径軸部１３が突設されている。大径軸部１３は、略円柱状に形成され、その底部には異形断面の取付軸１３ｃが下側に突設され、その取付軸１３ｃを、水平取付部１１に穿設した取付軸孔１１ａに嵌入して、大径軸部１３は水平取付部１１上にかしめ固定される。 On the other hand, the movable portion 10 is a member attached to the inner frame side of the game machine, and as shown in FIG. 2, the steel plate is bent into an L shape as a main body portion to form a horizontal attachment portion 11 and a vertical attachment portion 12. On the horizontal mounting portion 11, a large-diameter shaft portion 13 that is fitted into the bearing concave portion 13 of the fixed portion 1 is projected. The large-diameter shaft portion 13 is formed in a substantially columnar shape, and a mounting shaft 13c having an irregular cross section is provided on the bottom of the large-diameter shaft portion 13 so as to project downward, and the mounting shaft hole 11a is formed by drilling the mounting shaft 13c in the horizontal mounting portion 11. The large diameter shaft portion 13 is caulked and fixed on the horizontal mounting portion 11.

さらに、大径軸部１３の上面には、組み付け時に上記固定部側の突部５を導入するための、溝部１３ａが中心線上に、突部５を通すことが可能な幅と深さを持って形成されている。また、この溝部１３ａの一方の端部には、外側に向けて開く形状の開口部１３ｂが、突部５の挿入を容易とするように形成されている。また、この溝部１３ａの方向は、可動部１０を組み付ける際に移動させる方向に設定され、ここでは、垂直取付部１２の平面に沿った方向に設定される。 Further, the upper surface of the large-diameter shaft portion 13 has a width and depth that allows the groove portion 13a to pass the protrusion portion 5 on the center line for introducing the protrusion portion 5 on the fixed portion side during assembly. Is formed. In addition, an opening 13b having a shape that opens outward is formed at one end of the groove 13a so as to facilitate the insertion of the protrusion 5. In addition, the direction of the groove 13a is set to a direction to be moved when the movable unit 10 is assembled. Here, the direction is set to a direction along the plane of the vertical mounting portion 12.

なお、可動部１０の水平取付部１１上には、図示しない透明板扉のヒンジ軸を嵌め込むための軸受孔１１ｂが穿設されている。透明板扉は、中枠３１の前面に開閉可能に装着される扉であり、中枠３１に対しヒンジを介して装着される。そのヒンジ軸を受けるための軸受孔１１ｂが本蝶番の可動部１０の水平取付部１１に設けられることにより、可動部１０が透明板扉のヒンジ軸を支持することができ、透明板扉のヒンジ軸を支持する部材を別に設ける必要がなくなる。 Note that a bearing hole 11b for fitting a hinge shaft of a transparent plate door (not shown) is formed on the horizontal mounting portion 11 of the movable portion 10. The transparent plate door is a door that is attached to the front surface of the middle frame 31 so as to be openable and closable, and is attached to the middle frame 31 via a hinge. Since the bearing hole 11b for receiving the hinge shaft is provided in the horizontal mounting portion 11 of the movable portion 10 of the hinge, the movable portion 10 can support the hinge shaft of the transparent plate door, and the hinge of the transparent plate door. There is no need to provide a separate member for supporting the shaft.

上記構成の上部蝶番の固定部１は、図４〜図６に示すように、そのＬ字状に形成された取付板部２をゲーム機の本体枠３０の左上角部上に嵌め、その取付孔と取付ねじを使用して、ゲーム機の本体枠３０の正面から向かって左角部上に、その水平突出部３を前方に出した状態で固定される。 As shown in FIGS. 4 to 6, the fixing portion 1 of the upper hinge having the above configuration is fitted with the mounting plate portion 2 formed in an L shape on the upper left corner of the main body frame 30 of the game machine. Using the hole and the mounting screw, the horizontal protrusion 3 is fixed to the left corner portion from the front of the main body frame 30 of the game machine in a state where the horizontal protrusion 3 is projected forward.

一方、上部蝶番の可動部１０は、ゲーム機の中枠３１の正面に向かって左上角部に、その垂直取付部１２を中枠３１の背面側に固定して取り付けられる。中枠３１に固定された可動部１０は、図３のように、中枠３１を本体枠３０の対し略直角に位置させたとき、その大径軸部１３の溝部１３ａが中枠３１の平面に沿った方向を向くように装着される。 On the other hand, the movable part 10 of the upper hinge is attached to the upper left corner of the middle frame 31 of the game machine with the vertical attachment part 12 fixed to the back side of the middle frame 31. As shown in FIG. 3, the movable portion 10 fixed to the middle frame 31 has a groove 13 a of the large-diameter shaft portion 13 that is a flat surface of the middle frame 31 when the middle frame 31 is positioned substantially at right angles to the main body frame 30. It is mounted so as to face the direction along the.

一方、図示は省略されているが、ゲーム機の本体枠３０の下角部に、下部蝶番の固定部が取付られ、固定部はその水平取付板の突出端部にピンが上方に向けて垂直に固定され、更に、ゲーム機の中枠の下角部に、下部蝶番の可動部が取付られる。この可動部の水平取付板の突出端部に、軸受部となる軸受孔がピンを挿通可能に形成される。なお、下部蝶番においては、そのピンを可動部に設け、ピンが嵌る軸受部をその固定部に設けることもできる。 On the other hand, although not shown, a lower hinge fixing portion is attached to the lower corner portion of the main body frame 30 of the game machine, and the fixing portion is perpendicular to the protruding end portion of the horizontal mounting plate with the pin facing upward. In addition, a movable portion of a lower hinge is attached to the lower corner portion of the middle frame of the game machine. A bearing hole serving as a bearing portion is formed in the protruding end portion of the horizontal mounting plate of the movable portion so that the pin can be inserted. In addition, in a lower hinge, the pin can be provided in a movable part, and the bearing part in which a pin fits can also be provided in the fixed part.

中枠３１を本体枠３０に対し開閉可能に装着する場合、先ず、中枠３１を持って下部蝶番の可動部の軸受孔を、本体枠３０側の固定部のピンに嵌め込む。軸受孔は鋼板に穿設した孔であり、ピンと孔の嵌め合いには多少の間隙があるため、中枠３１は多少傾動可能である。 When the middle frame 31 is attached to the main body frame 30 so as to be openable and closable, first, the bearing hole of the movable part of the lower hinge is fitted into the pin of the fixed part on the main body frame 30 side. The bearing hole is a hole formed in the steel plate, and since there is a slight gap in the fitting between the pin and the hole, the inner frame 31 can be tilted somewhat.

次に、図３に示すように、その下部蝶番を支点にして中枠３１を本体枠３０に対し約９０度開いた状態で、少し右から左に傾けながら、上部蝶番の可動部１０の水平取付部１１を、固定部１の水平突出部３の右側の挿入開口部７から水平突出部３の内側に挿入する。 Next, as shown in FIG. 3, the horizontal frame of the movable unit 10 of the upper hinge is tilted slightly from right to left while the middle frame 31 is opened about 90 degrees with respect to the main body frame 30 with the lower hinge as a fulcrum. The mounting portion 11 is inserted into the horizontal protrusion 3 from the insertion opening 7 on the right side of the horizontal protrusion 3 of the fixed portion 1.

そして、水平取付部１１上の大径軸部１３の溝部１３ａ内に、その端部の開口部１３ｂから、固定部側の水平突出部３内の突部５を導入するように位置させる。そして、図３のように、中枠３１を手前に僅かに傾動させるように動かすと、固定部１の水平突出部３の突部５が大径軸部１３の溝部１３ａにガイドされてそこを通過する。これにより、可動部１０の水平取付部１１上の大径軸部１３は、固定部側の水平突出部３内の軸受凹部６内に正確に嵌入して回動可能に保持される状態となる。 And it positions so that the protrusion 5 in the horizontal protrusion part 3 by the side of a fixing | fixed part may be introduced in the groove part 13a of the large diameter shaft part 13 on the horizontal attachment part 11 from the opening part 13b of the edge part. Then, as shown in FIG. 3, when the middle frame 31 is moved so as to be slightly tilted forward, the protrusion 5 of the horizontal protrusion 3 of the fixed portion 1 is guided by the groove 13 a of the large-diameter shaft portion 13, thereby pass. As a result, the large-diameter shaft portion 13 on the horizontal mounting portion 11 of the movable portion 10 is accurately fitted into the bearing concave portion 6 in the horizontal protruding portion 3 on the fixed portion side and is held rotatably. .

このとき、突部５は、大径軸部１３の外周部の外側に位置し、所定の範囲（中枠の閉鎖位置から略９０度開放位置まで）内の回動時に、大径軸部１３の軸受凹部６からの離脱を阻止するように作用する。これにより、可動部１０はこの大径軸部１３と軸受凹部６を介して固定部１に回動可能に保持され、図７に示すように、中枠３１は、本体枠３０に対し、閉鎖位置から約９０度の開放位置まで回動可能に軸支される。 At this time, the protrusion 5 is located outside the outer peripheral portion of the large-diameter shaft portion 13, and when rotating within a predetermined range (from the closed position of the middle frame to the approximately 90-degree open position), the large-diameter shaft portion 13 Acts to prevent detachment from the bearing recess 6. As a result, the movable portion 10 is rotatably held by the fixed portion 1 via the large-diameter shaft portion 13 and the bearing recess 6, and the middle frame 31 is closed with respect to the main body frame 30 as shown in FIG. 7. It is pivotally supported from the position to an open position of about 90 degrees.

このように、本蝶番では、上面に溝部１３ａを有した可動部１０の大径軸部１３と、水平突出部３の内側に設けた固定部１の軸受凹部６との嵌合により、上部蝶番を組付けるため、従来のように、金属板が不要となり、部品点数を削減し、その取付のための作業工数を削減することができる。また、可動部１０の大径軸部１３が固定部１の軸受凹部６に回動可能に嵌合して可動部１０が支持されるため、つまり中枠３１の荷重を支持する軸が大径の軸部となるため、蝶番の耐荷重性が増大し、可動部１０に大荷重がかかる場合でも、可動部１０を円滑に回動させ、中枠３１の開閉を円滑に行なうことができる。 Thus, in this hinge, the upper hinge is fitted by fitting the large-diameter shaft portion 13 of the movable portion 10 having the groove portion 13 a on the upper surface and the bearing recess 6 of the fixed portion 1 provided inside the horizontal protrusion 3. Therefore, unlike the conventional case, a metal plate is not required, the number of parts can be reduced, and the number of work steps for the attachment can be reduced. Further, since the large-diameter shaft portion 13 of the movable portion 10 is rotatably fitted in the bearing recess 6 of the fixed portion 1 so that the movable portion 10 is supported, that is, the shaft that supports the load of the middle frame 31 has a large diameter. Therefore, even when a large load is applied to the movable part 10, the movable part 10 can be smoothly rotated and the middle frame 31 can be opened and closed smoothly.

さらに、可動部１０の大径軸部１３が固定部１の水平突出部３の軸受凹部６に嵌入した状態で、水平突出部３内側の突部５が大径軸部１３の離脱を阻止するため、所定の角度範囲内の中枠３１の開閉において、特に中枠３１が閉鎖された状態においては、大径軸部１３が軸受凹部６から外れることはなく、不正工具を差し込んで可動部を不正に外すなどの不正行為を防止することができる。 Further, in a state where the large-diameter shaft portion 13 of the movable portion 10 is fitted into the bearing recess 6 of the horizontal protrusion portion 3 of the fixed portion 1, the protrusion portion 5 inside the horizontal protrusion portion 3 prevents the large-diameter shaft portion 13 from being detached. Therefore, when the middle frame 31 is opened and closed within a predetermined angle range, particularly when the middle frame 31 is closed, the large-diameter shaft portion 13 does not come off from the bearing recess 6, and an improper tool is inserted to move the movable portion. Unauthorized actions such as unauthorized removal can be prevented.

一方、ゲーム機の修理や保守点検などの際、中枠３１を本体枠３０から外す際、蝶番の可動部１０を固定部１より外す場合、図３のように、中枠３１を本体枠３０の前方に約９０度開いた状態とし、この状態で、中枠３１つまり可動部１０を僅かに後方に傾ければ、大径軸部１３が軸受凹部６内から後方に外れ、その状態で、可動部１０を右側に動かせば、挿入開口部７から可動部１０の水平取付部１１を退出させ、固定部１から可動部１０を外すことができる。中枠３１を所定角度以上開かない閉鎖状態では、上記のように、突部５が障害となって大径軸部１３は軸受凹部６から外れるように移動できず、可動部１０つまり中枠３１を外すことはできない。
図８〜図１０は他の実施形態を示し、この例では、固定部１の水平突出部３の内側に設けた突部５の位置が、軸受凹部６の中央（軸心位置）に配置され、可動部１０の大径軸部３３の上面に設けた溝部３３ａは、その中央（軸心位置）部から外側に向けて形成されている。その他の部分は上記蝶番の実施形態と同様であるため、図面に同じ符号を付してその部分の説明を省略する。 On the other hand, when the middle frame 31 is removed from the main body frame 30 during repair or maintenance inspection of the game machine, the middle frame 31 is removed from the main body frame 30 as shown in FIG. In this state, if the middle frame 31, that is, the movable part 10 is tilted slightly rearward, the large-diameter shaft part 13 is detached rearward from the bearing recess 6, and in this state, If the movable part 10 is moved to the right side, the horizontal attachment part 11 of the movable part 10 can be withdrawn from the insertion opening 7 and the movable part 10 can be removed from the fixed part 1. In the closed state in which the middle frame 31 is not opened more than a predetermined angle, as described above, the projecting portion 5 becomes an obstacle, and the large-diameter shaft portion 13 cannot move so as to be disengaged from the bearing recess 6. Can not be removed.
8 to 10 show other embodiments. In this example, the position of the protrusion 5 provided inside the horizontal protrusion 3 of the fixed portion 1 is arranged at the center (axial center position) of the bearing recess 6. The groove portion 33a provided on the upper surface of the large-diameter shaft portion 33 of the movable portion 10 is formed outward from the center (axial center position) portion thereof. Since other parts are the same as those of the above-described hinge embodiment, the same reference numerals are given to the drawings, and description of those parts is omitted.

固定部１の水平突出部３には略円柱空間状の軸受凹部６が、下側に開口し且つ前部周囲を円弧状に曲面壁部４で囲って形成される。また、この水平突出部３の内側の軸受凹部６の中央（軸心位置）に、突部５５が下向きに突設される。この突部５５は円柱形に軸として形成されている。さらに、可動部１０の水平取付部１２上には、固定部１の軸受凹部６に嵌入可能な円柱状の大径軸部３３が突設される。この大径軸部３３の上面には、溝部３３ａが上面の中央（軸心位置）から外側に向けて、突部５５を挿通可能に形成されている。また、上記と同様に、水平突出部３の元部寄りには挿入開口部７が形成されている。 A bearing recess 6 having a substantially cylindrical space shape is formed in the horizontal projecting portion 3 of the fixed portion 1 so as to open on the lower side and surround the front portion with a curved wall portion 4 in an arc shape. In addition, a protrusion 55 is provided so as to protrude downward in the center (axial center position) of the bearing recess 6 inside the horizontal protrusion 3. The protrusion 55 is formed in a cylindrical shape as an axis. Further, a cylindrical large-diameter shaft portion 33 that can be fitted into the bearing recess 6 of the fixed portion 1 protrudes from the horizontal mounting portion 12 of the movable portion 10. On the upper surface of the large-diameter shaft portion 33, a groove portion 33a is formed so that the protrusion 55 can be inserted from the center (axial center position) of the upper surface toward the outside. Similarly to the above, an insertion opening 7 is formed near the base of the horizontal protrusion 3.

可動部１０を固定部１に組み付ける場合には、上記と同様に、図９に示すごとく、下部蝶番を支点にして中枠つまり可動部１０を本体枠つまり固定部１に対し約９０度開いた状態で、少し右から左に傾けながら、上部蝶番の可動部１０の水平取付部１１を、固定部１の水平突出部３の右側の挿入開口部７から水平突出部３の内側に挿入する。 When assembling the movable part 10 to the fixed part 1, as shown in FIG. 9, the middle frame, that is, the movable part 10 is opened about 90 degrees with respect to the main body frame, that is, the fixed part 1 with the lower hinge as a fulcrum. In this state, the horizontal mounting part 11 of the movable part 10 of the upper hinge is inserted into the horizontal protrusion part 3 from the right side of the horizontal opening part 7 of the horizontal protrusion part 3 of the fixed part 1 while being slightly tilted from right to left.

そして、水平取付部１１上の大径軸部３３の溝部３３ａ内に、固定部側の水平突出部３内の突部５５を導入するように位置させる。そして、図９のように、中枠つまり可動部１０を手前に僅かに傾動させるように動かすと、固定部１の水平突出部３の突部５５が大径軸部３３の溝部３３ａ内に進入し、可動部１０の動きがガイドされ、これにより、可動部１０の水平取付部１１上の大径軸部３３は、固定部側の水平突出部３内の軸受凹部６内に正確に嵌入して回動可能に保持された状態となる。 And it positions so that the protrusion 55 in the horizontal protrusion part 3 by the side of a fixing | fixed part may be introduce | transduced in the groove part 33a of the large diameter shaft part 33 on the horizontal attachment part 11. FIG. Then, as shown in FIG. 9, when the middle frame, that is, the movable portion 10 is moved so as to tilt slightly toward the front, the protrusion 55 of the horizontal protrusion 3 of the fixed portion 1 enters the groove 33 a of the large-diameter shaft portion 33. Then, the movement of the movable part 10 is guided, whereby the large-diameter shaft part 33 on the horizontal mounting part 11 of the movable part 10 is accurately fitted into the bearing recess 6 in the horizontal protruding part 3 on the fixed part side. To be held in a rotatable manner.

このとき、突部５５は、大径軸部３３の軸心位置の溝部３３ａに嵌り込み、所定の範囲（中枠の閉鎖位置から略９０度開放位置まで）内の回動時に、大径軸部３３の軸受凹部６からの離脱を阻止するように作用する。これにより、可動部１０はこの大径軸部３３と軸受凹部６を介して固定部１に回動可能に保持され、図１０に示すように、可動部１０つまり中枠は、固定部１つまり本体枠に対し、閉鎖位置から約９０度の開放位置まで回動可能に軸支される。 At this time, the protrusion 55 is fitted into the groove 33a at the axial center position of the large-diameter shaft portion 33, and when rotating within a predetermined range (from the closed position of the middle frame to the approximately 90-degree open position), the large-diameter shaft It acts to prevent the part 33 from being detached from the bearing recess 6. Thereby, the movable part 10 is rotatably held by the fixed part 1 via the large-diameter shaft part 33 and the bearing concave part 6, and as shown in FIG. The main body frame is pivotally supported so as to be rotatable from a closed position to an open position of about 90 degrees.

このように、本蝶番においても、上面に溝部３３ａを有した可動部１０の大径軸部３３と、水平突出部３の内側に設けた固定部１の軸受凹部６との嵌合により、上部蝶番を組付けるため、従来のように、金属板が不要となり、部品点数を削減し、その取付のための作業工数を削減することができる。また、可動部１０の大径軸部３３が固定部１の軸受凹部６に回動可能に嵌合して可動部１０が支持されるため、つまり中枠の荷重を支持する軸が大径の軸部となるため、蝶番の耐荷重性が増大し、可動部１０に大荷重がかかる場合でも、可動部１０を円滑に回動させ、中枠の開閉を円滑に行なうことができる。 As described above, in this hinge, the upper diameter shaft portion 33 of the movable portion 10 having the groove portion 33a on the upper surface and the bearing concave portion 6 of the fixed portion 1 provided inside the horizontal protruding portion 3 are fitted to each other. Since the hinge is assembled, a metal plate is not required as in the conventional case, the number of parts can be reduced, and the number of work steps for the attachment can be reduced. Further, since the large-diameter shaft portion 33 of the movable portion 10 is rotatably fitted in the bearing recess 6 of the fixed portion 1 so that the movable portion 10 is supported, that is, the shaft that supports the load of the middle frame has a large diameter. Since it becomes the shaft portion, the load resistance of the hinge is increased, and even when a large load is applied to the movable portion 10, the movable portion 10 can be smoothly rotated and the middle frame can be opened and closed smoothly.

さらに、可動部１０の大径軸部３３が固定部１の水平突出部３の軸受凹部６に嵌入した状態で、水平突出部３内側の突部５５が大径軸部３３の離脱を阻止するため、所定の角度範囲内の中枠の開閉において、特に中枠が閉鎖された状態においては、大径軸部３３が軸受凹部６から外れることはなく、不正工具を差し込んで可動部を不正に外すなどの不正行為を防止することができる。 Further, in a state where the large diameter shaft portion 33 of the movable portion 10 is fitted in the bearing recess 6 of the horizontal protrusion portion 3 of the fixed portion 1, the protrusion 55 inside the horizontal protrusion portion 3 prevents the large diameter shaft portion 33 from being detached. Therefore, when opening and closing the inner frame within a predetermined angle range, particularly when the middle frame is closed, the large-diameter shaft portion 33 does not come off from the bearing recess 6, and an unauthorized tool is inserted to improperly move the movable portion. Unauthorized acts such as removal can be prevented.
