Description

この発明は、本発明は自販機等の筐体の扉に使用されるヒンジ装置に関するものである。   The present invention relates to a hinge device used for a door of a housing of a vending machine or the like.

一般の自販機等では、固定枠体に取り付けたベース板の先端部に扉の基端部を単一軸構成のピボット型ヒンジによって連結している。しかしながら、このように扉の回転中心が固定枠体に近接した位置関係にあるヒンジでは、隣に同様の自販機等が設置されている場合には、扉を大きく開放したときに隣接の自販機等に扉が衝突する干渉事故の問題が指摘されている。この干渉事故を避けようとすると、今度は十分に扉を開放することができないため、ディスプレイや金銭収納用引き出し等の引き出し操作に障害となってしまう。
そこで、扉の回転中心が固定枠体の開口部前面側に持ち出されるため、扉が隣接の自販機等に衝突する干渉事故が発生せず、また、開放された扉が引き出し等の出し入れ操作の障害となることもない自販機等の持出し回転型ヒンジが提案されている（例えば特許文献１参照）。
このヒンジは、ベース板の先端部に固定歯車を固着し、アーム板の基端部の第１軸ピンを固定歯車の垂直軸孔に嵌挿し、アーム板に支持させた中間歯車を固定歯車に噛み合わせ、第１リンク板の先端部を第２軸ピンで扉に連結し、第１リンク板の基端部に固着した第３軸ピンをアーム板の軸受孔に嵌挿し、第３軸ピンに固設した回転軸歯車を固定歯車の反対側において中間歯車に噛み合わせ、第２リンク板の基端部を第４軸ピンによってアーム板の先端部に連結し、第２リンク板の先端部を第５軸ピンによって扉に連結したものである。
しかしながら、このヒンジは、機構が複雑で、比較的高価なものとなるという問題点がある。 In a general vending machine or the like, a base end portion of a door is connected to a distal end portion of a base plate attached to a fixed frame body by a pivot hinge having a single axis configuration. However, in the case where a similar vending machine is installed next to the hinge in which the rotation center of the door is close to the fixed frame body in this way, when the door is opened wide, the adjacent vending machine etc. The problem of the interference accident that the door collides is pointed out. If this interference accident is to be avoided, the door cannot be fully opened this time, which obstructs a drawer operation such as a display or a money storage drawer.
Therefore, since the center of rotation of the door is taken out to the front side of the opening of the fixed frame, there is no interference accident where the door collides with an adjacent vending machine, etc. A take-out rotary hinge such as a vending machine has been proposed (see, for example, Patent Document 1).
This hinge has a fixed gear fixed to the tip of the base plate, the first shaft pin at the base end of the arm plate is inserted into the vertical shaft hole of the fixed gear, and the intermediate gear supported by the arm plate is used as the fixed gear. The tip end of the first link plate is connected to the door by the second shaft pin, the third shaft pin fixed to the base end portion of the first link plate is fitted into the bearing hole of the arm plate, and the third shaft pin The rotation shaft gear fixed to the intermediate gear meshes with the intermediate gear on the opposite side of the fixed gear, the base end portion of the second link plate is connected to the tip portion of the arm plate by the fourth shaft pin, and the tip portion of the second link plate Is connected to the door by a fifth shaft pin.
However, this hinge has a problem that its mechanism is complicated and relatively expensive.

特開平１０−２５２３３８号公報JP-A-10-252338

したがって、この発明の目的は、扉が閉鎖状態にあるときには扉の回転中心が扉の垂直投影面内にあって、軸受が横外側へ張り出していないが、扉の開放時には、回転中心が固定枠体の開口部前面側の横外側にせり出されるため、開放された扉が隣接の自販機等に干渉することがなく、また内部の物の出し入れ操作の障害となることがない自販機等の筐体のせり出し回転型ヒンジ装置で、構造が比較的簡単で安価に得られるもの提供することである。   Accordingly, an object of the present invention is to have the center of rotation of the door in the vertical projection plane of the door when the door is in a closed state and the bearing does not project laterally outward, but when the door is opened, the center of rotation is the fixed frame. Cases of vending machines and the like that are opened to the outside of the front side of the body opening so that the opened doors do not interfere with adjacent vending machines and do not obstruct the operation of putting in and out the items inside. It is an object of the present invention to provide a protruding rotary type hinge device that has a relatively simple structure and can be obtained at low cost.

以下、添付図面の符号を参照して説明するが、本発明はこれに限定されるものではない。
上記課題を解決するためのこの出願に係る発明のヒンジ装置１は、固定枠体５２の開口前面５２ａ側を開閉する扉５３を固定枠体５２に開閉自在に枢支するためのヒンジであって、固定枠体５２に固着される水平のベース板２と、これに枢支される第１及び第２のリンク板３，４と、これらのリンク板３，４に枢支され、先端側に扉５３を枢支する支持板５とを具備する。第１のリンク板３は、ベース板２に、横外側方の第１の枢ピン６により一端側が枢支され、元位置とせり出し位置との間を水平面上回転可能である。第２のリンク板４は、ベース板２に、第１の枢ピン６より横内側方に位置する第２の枢ピン７で一端側が枢支され、元位置とせり出し位置との間を第１のリンク板３と平行に水平面上回転可能である。支持板５は、横内側方に位置する基端と横外側方に位置する先端とを有する。支持板５の基端側は、第１及び第２のリンク板３，４の他端側に、第３、第４の枢ピン８，９により枢支され、それにより、リンク板３，４に連動して元位置とせり出し位置との間を固定枠体５２の前面５２ａに対して平行を保ちながら水平面上揺動自在である。支持板５の先端側には、扉５３が枢軸５４で枢支される。支持板５は、それが元位置にある状態で、扉５３の垂直投影面内に配置され、せり出し位置にある状態では、当該投影面から前方及び横外側方へ張り出すように配置される。それにより、扉５３の開放時に、枢軸５４が開口前面５２ａの前方横外側方へせり出して配置される。 Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
The hinge device 1 of the invention according to this application for solving the above problems is a hinge for pivotally supporting a door 53 that opens and closes the opening front surface 52a side of the fixed frame 52 so as to be openable and closable on the fixed frame 52. The horizontal base plate 2 fixed to the fixed frame 52, the first and second link plates 3 and 4 pivotally supported by the horizontal base plate 2, and pivotally supported by the link plates 3 and 4 at the front end side. And a support plate 5 that pivotally supports the door 53. One end side of the first link plate 3 is pivotally supported on the base plate 2 by a first pivot pin 6 on the laterally outer side, and is rotatable on a horizontal plane between the original position and the protruding position. The second link plate 4 is pivotally supported on the base plate 2 by a second pivot pin 7 located laterally inward from the first pivot pin 6, and the first link between the original position and the protruding position is first. It can be rotated on a horizontal plane in parallel with the link plate 3. The support plate 5 has a proximal end located laterally inward and a distal end located laterally outward. The base end side of the support plate 5 is pivotally supported by the third and fourth pivot pins 8 and 9 on the other end side of the first and second link plates 3 and 4, thereby the link plates 3 and 4. In conjunction with this, it can be swung on a horizontal plane while keeping parallel between the original position and the protruding position with respect to the front surface 52a of the fixed frame 52. A door 53 is pivotally supported by a pivot 54 on the front end side of the support plate 5. The support plate 5 is arranged in the vertical projection plane of the door 53 in a state where it is in the original position, and is arranged so as to protrude forward and laterally outward from the projection plane in a state where it is in the protruding position. Thereby, when the door 53 is opened, the pivot shaft 54 is arranged to protrude to the front laterally outward side of the opening front surface 52a.

この出願に係る発明のヒンジ装置によれば、扉が閉鎖状態にあるときには、扉の回転中心が扉の垂直投影面内にあって、軸受が横外側へ張り出していないので、じゃまにならない。扉の開放時には、支持板の先端部が扉５３と共に前方から横外側方向へ移動することにより、扉の回転中心が固定枠体５２の開口部前方の横外側方向に持ち出されるため、開放された扉５３が隣接の自販機等に干渉することがなく、また内部の物の出し入れ操作の障害となることがない。また、構造が比較的簡単で安価に得られるという効果を有する。   According to the hinge device of the invention of this application, when the door is in the closed state, the center of rotation of the door is in the vertical projection plane of the door and the bearing does not protrude laterally outside, so that it does not get in the way. When the door is opened, the front end of the support plate moves from the front side to the laterally outer side together with the door 53, so that the rotation center of the door is taken out in the laterally outward direction in front of the opening of the fixed frame 52. The door 53 does not interfere with an adjacent vending machine or the like, and does not obstruct the operation of taking in and out the internal items. In addition, the structure is relatively simple and can be obtained at low cost.

図面を参照してこの発明の実施の形態を説明する。
図１において、５１は自動販売機等の筐体、５２は筐体１の前方開口を囲む固定枠体、５３は固定枠体５２の開口前面５２ａ側を開閉する扉である。図１において、筐体５１の一方の側壁５１ａ側（左側）を横外側方といい、その反対側（右側）、すなわち開口の中央側を横内側方という（この出願において同じ）。 Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, 51 is a housing such as a vending machine, 52 is a fixed frame surrounding the front opening of the housing 1, and 53 is a door that opens and closes the opening front surface 52 a side of the fixed frame 52. In FIG. 1, one side wall 51a side (left side) of the casing 51 is referred to as a laterally outer side, and the opposite side (right side), that is, the center side of the opening is referred to as a laterally inner side (the same applies in this application).

ヒンジ装置１は、固定枠体５２の横外側方の上下に設けられ、扉５３を枢軸５４で枢支する。ヒンジ装置１は、固定枠体５２に固着される水平のベース板２と、これに枢支される第１及び第２のリンク板３，４と、これらのリンク板に枢支され、先端側に扉５３を枢支する支持板５とを具備する。   The hinge device 1 is provided above and below the laterally outer side of the fixed frame body 52 and pivotally supports the door 53 with a pivot 54. The hinge device 1 includes a horizontal base plate 2 fixed to a fixed frame body 52, first and second link plates 3 and 4 pivotally supported by the base plate 2, and pivotally supported by these link plates. And the support plate 5 that pivotally supports the door 53.

第１のリンク板３は、直交する第１片３ａと第２片３ｂとからなり、第１片３ａの先端側において横外側方の第１の枢ピン６により、ベース板２に枢支され、図２に示す元位置と、図６に示すせり出し位置との間を水平面上回転可能である。第１のリンク板３は、元位置において、第１片３ａが固定枠体５２の開口前面５２ａに対して平行で、第２片３ｂが固定枠体５２の開口前面５２ａに対して直角に前方へ延びるように配置される。   The first link plate 3 is composed of a first piece 3a and a second piece 3b which are orthogonal to each other, and is pivotally supported on the base plate 2 by a first pivot pin 6 on the laterally outer side on the distal end side of the first piece 3a. 2 is rotatable on a horizontal plane between the original position shown in FIG. 2 and the protruding position shown in FIG. In the first link plate 3, the first piece 3 a is parallel to the opening front surface 52 a of the fixed frame body 52 and the second piece 3 b is frontward at a right angle to the opening front surface 52 a of the fixed frame body 52 at the original position. It is arranged to extend to.

第２のリンク板４は、同様に、直交する第１片４ａと第２片４ｂとからなり、第１片４ａの先端側において、第２の枢ピン７でベース板２に枢支され、図２に示す元位置と、図６に示すせり出し位置との間を水平面上回転可能である。第２の枢ピン７は、第１の枢ピン６の横内側方に位置して、開口前面５２ａに対して平行に並んで配置される。第２のリンク板４は、元位置において、第１片４ａが固定枠体５２の開口前面５２ａに対して平行で、第２片４ｂが固定枠体５２の開口前面５２ａに対して直角に前方へ延びるように配置される。   Similarly, the second link plate 4 is composed of a first piece 4a and a second piece 4b which are orthogonal to each other, and is pivotally supported by the base plate 2 with a second pivot pin 7 on the distal end side of the first piece 4a. It can rotate on a horizontal plane between the original position shown in FIG. 2 and the protruding position shown in FIG. The second pivot pin 7 is located laterally inward of the first pivot pin 6 and is arranged in parallel to the opening front surface 52a. As for the 2nd link board 4, the 1st piece 4a is parallel with respect to the opening front surface 52a of the fixed frame 52 in the original position, and the 2nd piece 4b is right front with respect to the opening front surface 52a of the fixed frame 52. It is arranged to extend to.

支持板５は、横内側方の基端と横外側の先端とを有し、図２に示す元位置において固定枠体５２の開口前面５２ａに対して平行に延びる。支持板５の基端側は、第１及び第２のリンク板３，４の他端側に、第３、第４の枢ピン８，９で枢支され、それにより、リンク板３，４に連動して図２に示す元位置と、図６に示すせり出し位置との間を固定枠体５２の前面５２ａに対して平行を保ちながら水平面上揺動自在である。扉５３の枢軸５４は、第１の枢ピン６よりも横外側方に配置される。支持板５は、それが図２に示す元位置にある状態で、扉５３の垂直投影面内に配置され、図６に示すせり出し位置にある状態では、扉５３の投影面から前方及び横外側方へ張り出すように配置される。それにより、扉５３の開放時に、枢軸５４が開口前面５２ａの前方横外側方へせり出して配置される。   The support plate 5 has a laterally inner base end and a laterally outer distal end, and extends parallel to the opening front surface 52a of the fixed frame 52 at the original position shown in FIG. The base end side of the support plate 5 is pivotally supported by the third and fourth pivot pins 8 and 9 on the other end side of the first and second link plates 3 and 4, whereby the link plates 3 and 4 are supported. 2 is swingable on a horizontal plane while maintaining parallel to the front surface 52a of the fixed frame 52 between the original position shown in FIG. 2 and the protruding position shown in FIG. The pivot 54 of the door 53 is disposed laterally outward from the first pivot pin 6. The support plate 5 is disposed in the vertical projection plane of the door 53 in a state where the support plate 5 is at the original position shown in FIG. It is arranged so as to protrude toward the direction. Thereby, when the door 53 is opened, the pivot shaft 54 is arranged to protrude to the front laterally outward side of the opening front surface 52a.

ストッパロッド１０は、固定枠体５２に固定された支持部材１１に、上下動自在に設けられる。ストッパロッド１０は、支持部材１１のガイド溝１１ａに挿通されたハンドル１０ａを摘んで手動により上下操作可能であり、下降して下端部が第１のリンク板３の回転経路上に進出したロック位置において、リンク板３を元位置に保持し、上昇して回転経路上から退去した解放位置においてリンク板３の回動を許容する。ストッパロッド１０は、扉５３の閉鎖状態においてロック位置に配置する。   The stopper rod 10 is provided on the support member 11 fixed to the fixed frame 52 so as to be movable up and down. The stopper rod 10 can be manually operated up and down by picking the handle 10a inserted into the guide groove 11a of the support member 11, and the lower end of the stopper rod 10 is advanced to the rotation path of the first link plate 3 , The link plate 3 is held at the original position, and the link plate 3 is allowed to rotate at the release position where the link plate 3 is lifted and withdrawn from the rotation path. The stopper rod 10 is disposed at the lock position when the door 53 is closed.

図２に示す閉鎖状態において、リンク板３，４はストッパロッド１０で元位置に拘束されている。扉５３を開放操作すると、扉５３は枢軸５４を中心に、図３の経過を経て図４の位置まで時計方向へ回動し、ここで図示しないストッパ機構により扉５３と支持板５との相対回動が止まる。この状態で、ストッパロッド１０を解放位置へ引き上げ、リンク板３，４を解放し、さらに扉５４を時計方向へ回動操作すると、リンク板３，４が枢ピン６，７を中心に時計方向へ回動し、支持板５が固定枠体５２の前面５２ａに対して平行を保ちながら図５の経過を経て図６の位置まで前方横外側方へせり出す。このため、開放された扉５３が隣接の自販機等に干渉することがなく、また内部の物の出し入れ操作の障害となることがない。
扉５３を閉じる場合には、まずリンク板３，４を元位置へ復帰させるように、反時計方向へ回動させるべく扉５３を操作する。図３に示すように、リンク板３，４が元位置へ復帰した状態で、ストッパロッド１０をロック位置へ降ろした上、さらに扉５３を枢軸５４を中心に反時計方向へ回動させ、図２に示す閉鎖位置へ戻し、筐体５１の開口を閉じる。
なお、ストッパロッド１０がなくても、扉５３の開閉操作を行うことができる。 In the closed state shown in FIG. 2, the link plates 3 and 4 are restrained to the original positions by the stopper rod 10. When the door 53 is opened, the door 53 rotates about the pivot 54 in the clockwise direction up to the position of FIG. 4 through the passage of FIG. 3, and the door 53 and the support plate 5 are relative to each other by a stopper mechanism (not shown). The rotation stops. In this state, when the stopper rod 10 is pulled up to the release position, the link plates 3 and 4 are released, and the door 54 is further rotated clockwise, the link plates 3 and 4 are rotated clockwise around the pivot pins 6 and 7. , And the support plate 5 protrudes forward and laterally outward to the position of FIG. 6 through the passage of FIG. 5 while keeping parallel to the front surface 52a of the fixed frame 52. For this reason, the opened door 53 does not interfere with an adjacent vending machine or the like, and does not become an obstacle to the operation of taking in and out the internal items.
When closing the door 53, first, the door 53 is operated to rotate counterclockwise so that the link plates 3 and 4 are returned to their original positions. As shown in FIG. 3, with the link plates 3 and 4 returned to their original positions, the stopper rod 10 is lowered to the lock position, and the door 53 is further rotated counterclockwise around the pivot 54. 2 is returned to the closed position, and the opening of the casing 51 is closed.
Even if the stopper rod 10 is not provided, the door 53 can be opened and closed.
