Description

【０００１】
【発明の属する技術分野】
本発明は、自動販売機の本体前面に配した片開き式メイン扉の扉ヒンジ装置に関する。
【０００２】
【従来の技術】
まず、図３(a) 〜(c) に頭記した自動販売機の外観を示す。図において、１は庫内に商品収納ラックを搭載した断熱筐体になる自動販売機の本体、２は本体１の前面に配した片開き式のメイン扉であり、メイン扉２はその吊り側（左側）の上，下端部がヒンジ３およびヒンジ４を介して本体１に枢支連結されている。なお、５はメイン扉２に設けた商品ディスプレイ室、６は商品取出口、７，８は扉の裏面側に装備したコイン機構，ビルバリデータに通じるコイン投入口，紙幣挿入口、９は扉の吊り側と反対側（右端）に設けた扉ロックである。
【０００３】
次に、前記したメイン扉２の上端部を枢支する上部側のヒンジ３について、従来から実施されている組立構造を図４(a),(b) に示す。すなわち、上部側のヒンジ３は、本体１の天板上面に取付けた強じん鋼で作られたヒンジプレート１０と、ヒンジプレート１０の先端部１０ａに植設してメイン扉２の扉本体に嵌挿したヒンジ軸（強じん鋼で作られたボルトあるいはピン）１１からなる。ここで、ヒンジプレート１０はボルト１２およびナット１２ａを介して本体１の天板に強固に固着される。一方、ヒンジ軸１１は、ヒンジプレート１０の先端部１０ａに開口した軸穴に圧入してかしめ止めするか，もしくはヒンジ軸の頭部をヒンジプレート１０に溶接して抜けないように固着しており、さらにヒンジ軸１１には高周波焼入れ法などにより硬化処理を施し、電動鋸などを使って外部からヒンジ軸を切断し、メイン扉を外して機内から金銭を盗み出す盗難行為に対する防盗性を高めるようにしている（例えば、特許文献１，特許文献２参照。）。

【特許文献２】
特開平１０−１３１５９４号公報
【０００５】
【発明が解決しようとする課題】
ところで、前記した従来構造のヒンジ装置には、次記のような問題点がある。すなわち、
(1) ヒンジ軸１１をヒンジプレート１０にかしめ止めした構造では、その接合面を完全に塞ぐことができず、自動販売機を屋外に設置した場合には、ヒンジプレート１０の軸穴とヒンジ軸１１との間に生じた隙間に雨水が浸透し、錆が発生してヒンジ部が腐食され易くなるほか、隙間に浸透した雨水がヒンジ軸１１を伝わってメイン扉２の内部に浸入するおそれがあり、このためヒンジプレート１０にヒンジ軸１１をかしめ止めした後は、その接合部に防水シールを施して雨水の浸透を防ぐ必要がある。
【０００６】
(2) 一方、ヒンジ軸１１の頭部周縁をヒンジプレート１０に溶接（アーク溶接）した構造は高い接合強度が得られるほか、かしめ止め構造のように組立ラインのプレス設備などを必要とせず、例えば自動販売機のロケーション先でヒンジ装置の補修作業（部品交換）を行う場合でも溶接機を使った手溶接作業で容易に対応でき、しかもヒンジ軸とヒンジプレートとの間の接合面を隙間なく溶接材で塞ぐことができるので雨水の浸透を防止するシールも不要となるなどの利点がある反面、防盗機能の面で次のような問題点がある。
すなわち、あらかじめ軸部の表面を高周波焼入れして硬化処理しておいたヒンジ軸１１を使ってその頭部をヒンジプレート１０にアーク溶接すると、高温アーク熱が溶接箇所からヒンジ軸の軸部に伝熱して軸部の焼入れが戻ってしまい、そのためにヒンジ軸の表面硬度が低下して電動鋸などを使ってヒンジ軸を切断する破壊行為に対して期待した防盗性が確保できなくなる。
【０００７】
本発明は上記の点に鑑みなされたものであり、その目的は前記課題を解決し、ヒンジ軸をヒンジプレートにかしめ止めする構造と比べて接合強度，作業性，雨水浸透に対する防水性の面で優れた溶接構造を採用しつつ、しかも電動鋸などを使った破壊行為に対して高い防盗性が確保できるように改良した自動販売機の扉用ヒンジ装置を提供することにある。
【０００８】
【課題を解決するための手段】
上記目的を達成するために、本発明によれば、自動販売機の本体前面に配したメイン扉を開閉自在に支持する扉ヒンジ装置であり、本体側に取付けたヒンジプレートにヒンジ軸を植設し、該ヒンジ軸の先端をメイン扉の扉本体に嵌挿して枢支したものにおいて、
請求項１の発明では、前記のヒンジ軸を、ヒンジボルトと、該ヒンジボルトに螺合する雌ねじを内径側に形成した上で焼入硬化処理を施したヒンジ軸の補強カラーとの２部品で構成し、ヒンジボルトをヒンジプレートに穿孔した軸穴に通し、かつヒンジボルトの頭部周縁をヒンジプレートに溶接した上で、ヒンジボルトの軸部に前記補強カラーを螺合して固定するものとする。
【０００９】
また、請求項２の発明では、前記のヒンジ軸を、頭部付きヒンジピンと、焼入硬化処理を施して前記ヒンジピンの軸部に嵌挿するヒンジ軸の補強カラーとの２部品で構成し、かつ補強カラーはその一端側に凸状フランジ部を形成してその周面に雄ねじをねじ立てするとともに、ヒンジプレートには補強カラーの雄ねじと螺合する雌ねじを立てた座ぐり部を形成し、ヒンジピンをヒンジプレートに穿孔した軸穴に通してヒンジピンの頭部周縁をヒンジプレートに溶接した上で、ヒンジピンの軸部に通した補強カラーをヒンジプレートの座ぐり部に螺合して固定するものとする。
【００１０】
上記のようにヒンジ軸をボルトあるいは頭付きヒンジピンと、表面を焼入硬化処理したヒンジ軸の補強カラーとの２部品で構成し、自動販売機への組付けに際しては、補強カラーを外した状態で、ヒンジ軸をヒンジプレートの軸穴に通してその頭部周縁をヒンジプレートに溶接接合し、その後に補強カラーをヒンジボルトあるいはヒンジピンの軸部に通してねじ止め固定することにより、あらかじめ焼入硬化処理した補強カラーはヒンジ軸を溶接時に熱的な影響を受けて焼入れが戻ってしまう不具合を回避できる。しかも、ヒンジボルトないしヒンジピンの軸部に補強カラーを被せることで、ヒンジ軸は補強カラーの肉厚分が加わって実質的な軸の太さが増し、これにより電動鋸などを使ってヒンジ軸を切断する不正な破壊行為に対して高い防盗性を確保できる。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を図１，図２に示す実施例に基づいて説明する。なお、各実施例の図中で図３，図４に対応する部材には同じ符号を付してその説明は省略する。
〔実施例１〕
まず、図１(a),(b) に本発明の請求項１に対応するヒンジ装置の主要部構造を示し、図１(a) はヒンジプレート１０にヒンジ軸を植設した組立状態、また図１(b) はその組立工程の説明図である。
【００１２】
この実施例においては、ヒンジプレート１０に植設するヒンジ軸がヒンジボルト１３と、ヒンジボルト１３の軸部１３ａに螺合した補強カラー１４との２部品からなり、補強カラー１４はその内径側に雌ねじ１４ａを立てた上で、高周波焼入れ法などにより表面が硬化処理されている。
そして、ヒンジ装置の組立に際しては、先ずヒンジボルト１３をヒンジプレート１０に穿孔した軸穴１０ｂへ図示矢印のように上方から差込み（工程Ｉ）、続いてヒンジボルト１３の頭部１３ｂの外周縁全域に沿ってヒンジプレート１０との間を溶接接合する（工程II) 。なお、図中には溶接部（溶接継手）をＷで示す。次にヒンジボルト１３の軸部１３ａに補強カラー１４をねじ込んで固定する（工程III)。その後に、図４のようにヒンジプレート１０を自動販売機の本体１に固定してメイン扉２を枢支する。
【００１３】
この構造によれば、補強カラー１４を外した状態でヒンジボルト１３をヒンジプレート１０に溶接し、溶接後にヒンジボルト１３に補強カラー１４を螺合するようにしたので、補強カラー１４は溶接熱の影響を受けて焼入れが戻ることはない。しかも、図１(a) に示す組立状態では、ヒンジ軸の根元部分がヒンジボルト１４の外周に焼入硬化処理した補強カラー１４が重なった二重構造となるので、図３の自動販売機に対してメイン扉２の上面とヒンジプレート１０との間の残る隙間に電動鋸を差し入れてヒンジ軸を切断しようとしても、簡単にヒンジ軸を切断することができず、これにより防盗性が大幅に高まる。また、ヒンジプレート１０に対してヒンジボルト１３の頭部周縁が溶接されているので、この接合部に雨水の浸透を防ぐシールを施す必要もない。
【００１４】
〔実施例２〕
図２(a),(b) は本発明の請求項２に対応する実施例を示すものである。この実施例では、ヒンジ軸が頭部付きヒンジピン１５と、ヒンジピン１５の軸部１５ａに嵌合する補強カラー１６との２部品から構成されている。ここで、補強カラー１６はその上端側に凸状フランジ部１６ａを有し、その外周面に雄ねじ１６ａ-1を形成した上で、実施例１の補強カラー１４と同様に高周波焼入れにより硬化処理されている。また、ヒンジプレート１０の下面側には、前記補強カラー１６の凸状フランジ部１６ａに対応した座ぐり部１０ｂを形成し、この座ぐり部１０ｂの内周面には雌ねじ１０ｂ-1を立てておく。
【００１５】
そして、ヒンジ装置の組立時には、ヒンジピン１５をヒンジプレート１０に穿孔した軸穴へ図示矢印のように上方から差込み（工程Ｉ）、ヒンジピン１５の頭部１５ｂをヒンジプレート１０に溶接接合する（工程II) 。その後に、ヒンジピン１５の軸部１５ａに補強カラー１６を嵌挿し、その凸状フランジ部１６ａの雄ねじ１６ａ-1をヒンジプレート１０の座ぐり部１０ｂに形成した雌ねじ１０ｂ-1に螺合して補強カラー１５を図２(a) の組立位置に固定する。
これにより、先記実施例１と同様に電動鋸を使ってヒンジ軸を切断する破壊行為に対して高い防盗性を確保することができる。
【００１６】
【発明の効果】
以上述べたように、本発明の構成によれば、メイン扉を枢支するヒンジ軸を、ボルトあるいは頭付きヒンジピンと、表面を焼入硬化処理したヒンジ軸の補強カラーとの２部品で構成し、自動販売機への組付時には、先にヒンジ軸をヒンジプレートの軸穴に通してその頭部周縁をヒンジプレートに溶接接合し、その後に補強カラーをヒンジボルトあるいはヒンジピンの軸部に通してねじ止め固定して組立てたことにより、
あらかじめ焼入硬化処理した補強カラーが、ヒンジ軸の溶接による熱的な影響を受けて焼入れが戻ってしまう不具合を回避できる。しかも、ヒンジボルトないしヒンジピンの軸部に補強カラーを被せることで、ヒンジ軸は補強カラーの肉厚分が加わって実質的な軸の太さが増し、これにより電動鋸などを使ってヒンジ軸を切断する不正な破壊行為に対して高い防盗性を確保できる。また、ヒンジ軸の頭部周縁をヒンジプレートに溶接したことで、雨水浸透を防ぐシール処理の必要もないなど、優れた効果を発揮する自動販売機の扉用ヒンジ装置を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a door hinge device for a single-open main door disposed on the front surface of a main body of a vending machine.
[0002]
[Prior art]
First, the appearance of the vending machine described in FIGS. 3 (a) to 3 (c) is shown. In the figure, 1 is a main body of a vending machine that becomes a heat-insulating housing with a product storage rack mounted in the cabinet, 2 is a single-opening main door disposed on the front surface of the main body 1, and the main door 2 is on its suspension side. The upper and lower ends of the (left side) are pivotally connected to the main body 1 via hinges 3 and 4. In addition, 5 is a commodity display room provided in the main door 2, 6 is a commodity outlet, 7, 8 is a coin mechanism equipped on the back side of the door, a coin insertion slot leading to a bill validator, a bill insertion slot, 9 is a door It is a door lock provided on the opposite side (right end) to the suspension side.
[0003]
Next, FIGS. 4A and 4B show a conventional assembly structure of the upper hinge 3 pivotally supporting the upper end portion of the main door 2 described above. That is, the upper hinge 3 is fitted to the door body of the main door 2 by being implanted in the hinge plate 10 made of strong steel attached to the top surface of the top plate of the main body 1 and the tip 10 a of the hinge plate 10. It consists of an inserted hinge shaft (bolt or pin made of strong steel) 11. Here, the hinge plate 10 is firmly fixed to the top plate of the main body 1 via bolts 12 and nuts 12a. On the other hand, the hinge shaft 11 is fixed by press-fitting into a shaft hole opened at the tip portion 10a of the hinge plate 10 or by fixing the head of the hinge shaft to the hinge plate 10 so as not to come off. In addition, the hinge shaft 11 is hardened by induction hardening, etc., and the hinge shaft is cut from the outside using an electric saw, etc., and the main door is removed to enhance the anti-theft performance against theft that steals money from inside the machine.

[Patent Document 1]
Japanese Patent Laid-Open No. 10-169290 [Patent Document 2]
Japanese Patent Laid-Open No. 10-131594
[Problems to be solved by the invention]
Incidentally, the conventional hinge device has the following problems. That is,
(1) In the structure in which the hinge shaft 11 is caulked to the hinge plate 10, the joint surface cannot be completely blocked. When the vending machine is installed outdoors, the shaft hole of the hinge plate 10 and the hinge shaft In addition to rainwater penetrating into the gap formed between the door 11 and the rust, the hinge portion is easily corroded, and the rainwater penetrating into the gap may pass through the hinge shaft 11 and enter the main door 2. For this reason, after the hinge shaft 11 is caulked and secured to the hinge plate 10, it is necessary to provide a waterproof seal at the joint to prevent rainwater from penetrating.
[0006]
(2) On the other hand, the structure in which the periphery of the head of the hinge shaft 11 is welded (arc welding) to the hinge plate 10 provides high joint strength, and does not require press equipment on the assembly line as in the case of the caulking prevention structure. For example, even when repairing a hinge device (part replacement) at the location of a vending machine, it can be easily handled by a manual welding operation using a welding machine, and the joint surface between the hinge shaft and the hinge plate is free of gaps. Since it can be sealed with a welding material, there is an advantage that a seal for preventing the penetration of rainwater is unnecessary, but there is the following problem in terms of the anti-theft function.
That is, when the head of the shaft is arc-welded to the hinge plate 10 using the hinge shaft 11 whose surface has been hardened by induction hardening, high-temperature arc heat is transferred from the welded portion to the shaft of the hinge shaft. Heating causes the shaft portion to return to quenching, so that the surface hardness of the hinge shaft decreases, and the anti-theft property expected for the destructive action of cutting the hinge shaft using an electric saw or the like cannot be ensured.
[0007]
The present invention has been made in view of the above points, and the object thereof is to solve the above-mentioned problems, in terms of joint strength, workability, and waterproofness against rainwater penetration compared to a structure in which the hinge shaft is caulked to the hinge plate. An object of the present invention is to provide an improved door hinge device for a vending machine that employs an excellent welded structure and is improved so as to ensure high anti-theft performance against vandalism using an electric saw or the like.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, there is a door hinge device that supports a main door disposed on the front surface of a main body of a vending machine so that it can be opened and closed, and a hinge shaft is implanted in a hinge plate attached to the main body side. In the case where the tip of the hinge shaft is inserted into the door body of the main door and pivotally supported,
According to the first aspect of the present invention, the hinge shaft is composed of two parts: a hinge bolt and a reinforcing collar of the hinge shaft that has been hardened and hardened after forming a female screw that is screwed into the hinge bolt on the inner diameter side. The hinge bolt is passed through a shaft hole drilled in the hinge plate, and the periphery of the head of the hinge bolt is welded to the hinge plate, and the reinforcing collar is screwed and fixed to the shaft portion of the hinge bolt; To do.
[0009]
Moreover, in invention of Claim 2, the said hinge axis | shaft is comprised by two parts of the hinge pin with a head, and the reinforcement collar of the hinge axis | shaft which performs a hardening hardening process and inserts in the axial part of the said hinge pin, The reinforcing collar is formed with a convex flange portion at one end thereof, and a male screw is tapped on the peripheral surface thereof, and a counterbore portion is formed on the hinge plate with a female screw screwed with the male screw of the reinforcing collar, The hinge pin is passed through the shaft hole drilled in the hinge plate and the head periphery of the hinge pin is welded to the hinge plate. And
[0010]
As shown above, the hinge shaft is composed of two parts: the bolt or head hinge pin and the hinge shaft reinforcement collar whose surface has been hardened and hardened, and the reinforcement collar is removed when assembling to the vending machine. Then, the hinge shaft is passed through the shaft hole of the hinge plate and the periphery of the head is welded to the hinge plate, and then the reinforcement collar is passed through the shaft of the hinge bolt or hinge pin and fixed by screwing. The reinforcing collar that has been subjected to the curing treatment can avoid a problem that the hinge shaft is thermally affected during welding to return to quenching. In addition, by covering the hinge bolt or hinge pin shaft with the reinforcement collar, the hinge shaft is added with the thickness of the reinforcement collar, increasing the substantial shaft thickness. A high anti-theft property can be secured against an illegal destruction act of cutting.
