Description

本発明は、冷蔵庫の扉の回転軸となるヒンジを含むヒンジアッセンブリ、及びこのヒンジアッセンブリが取り付けられた冷蔵庫に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge assembly including a hinge serving as a rotating shaft of a refrigerator door, and a refrigerator to which this hinge assembly is attached.

冷蔵庫の中には、扉の開閉を検知するドアスイッチが、冷蔵庫本体の上面の扉のヒンジの近傍に配置されているものがある。そのような冷蔵庫の中には、ヒンジを覆うヒンジカバーの内側にドアスイッチが取り付けられたものが提案されている（例えば、特許文献１参照）。特許文献１に記載の冷蔵庫では、ドアスイッチがヒンジカバーに覆われるので、美観に優れた冷蔵庫を提供できる。 2. Description of the Related Art Some refrigerators have a door switch for detecting the opening and closing of the door, which is arranged near the hinge of the door on the upper surface of the refrigerator body. Among such refrigerators, there has been proposed one in which a door switch is attached inside a hinge cover that covers the hinge (see, for example, Patent Document 1). In the refrigerator disclosed in Patent Literature 1, the door switch is covered with the hinge cover, so that the refrigerator can be provided with excellent appearance.

しかしながら、特許文献１に記載の冷蔵庫では、ヒンジの冷蔵庫本体への取付作業と、ヒンジカバー取り付けを伴うドアスイッチの冷蔵庫本体への取付作業の二度の作業を行う必要がある。また、ヒンジカバーの内側にドアスイッチに繋がる配線も存在するので、ヒンジカバーを冷蔵庫本体に取り付けるとき、配線が垂れ下がって干渉するため、多くの作業時間を要する虞がある。更に、ヒンジカバーを取り付けた後、ヒンジカバー内の配線等に押されて、ヒンジカバーが浮き上がる可能性があり、その場合には、ドアスイッチが正しく機能しない虞がある。 However, in the refrigerator described in Patent Document 1, it is necessary to perform two operations, one for attaching the hinge to the refrigerator main body and the other for attaching the door switch to the refrigerator main body along with the attachment of the hinge cover. In addition, since wiring connected to the door switch is also present inside the hinge cover, when the hinge cover is attached to the refrigerator body, the wiring hangs down and interferes, which may require a lot of work time. Furthermore, after the hinge cover is attached, there is a possibility that the hinge cover may be lifted up by being pushed by wiring or the like inside the hinge cover, in which case the door switch may not function properly.

従って、本発明の目的は、上記の課題を解決するものであり、ヒンジ及びドアスイッチ基板を含む電子機器を少ない作業時間で容易に冷蔵庫本体に取り付けることができるとともに、取り付けられたドアスイッチ基板を含む電子機器の位置を確実に保持することができるヒンジアッセンブリ及びこのヒンジアッセンブリが取り付けられた冷蔵庫を提供することにある。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems, and to enable an electronic device including a hinge and a door switch board to be easily attached to a refrigerator body in a short work time, and to remove the attached door switch board. To provide a hinge assembly capable of surely holding the position of an electronic device including the hinge assembly, and a refrigerator fitted with the hinge assembly.

図１は、冷蔵庫１００の上側の領域を斜め前側から示している。冷蔵庫１００は、冷蔵庫本体５０と、冷蔵庫本体５０に回転自在に取り付けられた２つの扉５２Ａ，５２Ｂとを備える。２つの扉５２Ａ，５２Ｂは、左右に開く観音開きの扉である。扉５２Ａ，５２Ｂの回転軸となるヒンジのうち、上側のヒンジが冷蔵庫本体５０の上面５０Ａに取り付けられている。上側のヒンジは、ヒンジカバー４，４’で覆われている。図２Ａでは、右側の扉５２Ａの上側のヒンジ周辺が拡大して示され、ヒンジカバー４が取り外されて、本発明の１つの実施形態に係るヒンジアセンブリ２が、冷蔵庫本体５０の上面５０Ａに取り付けられているのが示されている。更に、図２Ｂでは、ヒンジアセンブリ２を冷蔵庫本体５０に固定する締結部材４０が取り外されて、ヒンジアッセンブリ２が冷蔵庫本体５０から取り外されたところを示す。左側の扉５２Ｂの上側のヒンジ周辺についても、ヒンジカバー４’で覆われたヒンジアッセンブリ２’が、冷蔵庫本体５０に取り付けられている FIG. 1 shows the upper region of the refrigerator 100 from the oblique front side. The refrigerator 100 includes a refrigerator body 50 and two doors 52A and 52B rotatably attached to the refrigerator body 50. - 特許庁The two doors 52A and 52B are double doors that open to the left and right. Of the hinges serving as the rotation shafts of the doors 52A and 52B, the upper hinge is attached to the upper surface 50A of the refrigerator main body 50. As shown in FIG. The upper hinge is covered with hinge covers 4, 4'. In FIG. 2A, the upper hinge periphery of the right door 52A is shown enlarged, the hinge cover 4 is removed, and the hinge assembly 2 according to one embodiment of the present invention is attached to the top surface 50A of the refrigerator body 50. is shown. Further, FIG. 2B shows that the hinge assembly 2 has been removed from the refrigerator body 50 by removing the fastening member 40 that secures the hinge assembly 2 to the refrigerator body 50 . A hinge assembly 2' covered with a hinge cover 4' is attached to the refrigerator body 50 also around the upper hinge of the left door 52B.

図３Ａには、取り外された右側のヒンジアッセンブリ２の構成部材を分解した状態が示されている。図３Ｂには、取り外された左側のヒンジアッセンブリ２’の構成部材を分解した状態が示されている。ヒンジアッセンブリ２，２’は、板状部１２及び板状部１２から立設した扉の回転軸となるヒンジ１４を有する金属製のヒンジ部材１０を備える。更に、板状部１２と係合する樹脂製のヒンジ係合部材２０と、ヒンジ係合部材２０の上面に取り付けられた配線３６を伴う電子機器３０，３２，３４を備える。左右のヒンジアッセンブリ２，２’の板状部１２、ヒンジ係合部材２０は、対称な形状を有している。 FIG. 3A shows a disassembled state of the components of the removed right hinge assembly 2 . FIG. 3B shows an exploded view of the components of the removed left hinge assembly 2'. The hinge assembly 2, 2' comprises a metal hinge member 10 having a plate-like portion 12 and a hinge 14 erected from the plate-like portion 12 and serving as a rotation axis of the door. Furthermore, the electronic devices 30 , 32 , 34 are provided with a hinge engaging member 20 made of resin that engages with the plate-like portion 12 and wiring 36 attached to the upper surface of the hinge engaging member 20 . The plate-like portions 12 of the left and right hinge assemblies 2, 2' and the hinge engaging members 20 have symmetrical shapes.

電子機器３０，３２，３４について、更に詳細に述べれば、ドアスイッチ基板３０、湿度センサ３２及びＷＩＦＩ通信ユニット３４がヒンジ係合部材２０の上面に取り付けられている。特に、ドアスイッチ基板３０は、左右両方のヒンジアッセンブリ２，２’に取り付けられている。湿度センサ３２は、右側のヒンジアッセンブリ２にだけ取り付けられている。ＷＩＦＩ通信ユニット３４は、左側のヒンジアッセンブリ２’にだけ取り付けられている。各電子機器３０，３２，３４には配線３６が接続され、幾つかの配線３６の端部には端子３６Ａが取り付けられている。ドアスイッチ基板３０には、コネクタ３０Ａにより配線３６が接続さている。 With respect to the electronics 30 , 32 , 34 in more detail, a door switch board 30 , a humidity sensor 32 and a WIFI communication unit 34 are mounted on the upper surface of the hinge engaging member 20 . In particular, the door switch board 30 is attached to both the left and right hinge assemblies 2, 2'. A humidity sensor 32 is attached only to the right hinge assembly 2 . A WIFI communication unit 34 is attached only to the left hinge assembly 2'. Wires 36 are connected to each of the electronic devices 30, 32, 34, and terminals 36A are attached to the ends of some of the wires 36. FIG. A wiring 36 is connected to the door switch substrate 30 by a connector 30A.

ドアスイッチ基板３０は、ヒンジアッセンブリ２，２’を冷蔵庫本体５０に取り付けたとき、冷蔵庫本体５０の前端に位置するように配置されている。ドアスイッチ基板３０としては、扉５２Ａとの物理的接触によりスイッチのオンオフを行うタクトスイッチまたはトグルスイッチや、電磁的に扉５２Ａと近接しているか否かを判断する近接スイッチを例示できる。ドアスイッチ基板３０が冷蔵庫本体５０の前端に位置することにより、扉５２Ａの開閉を正確に検出することができる。 The door switch board 30 is arranged so as to be positioned at the front end of the refrigerator body 50 when the hinge assemblies 2 and 2' are attached to the refrigerator body 50. - 特許庁Examples of the door switch board 30 include a tact switch or a toggle switch that turns on and off by physical contact with the door 52A, and a proximity switch that electromagnetically determines whether or not the door 52A is in proximity. By locating the door switch board 30 at the front end of the refrigerator main body 50, the opening/closing of the door 52A can be accurately detected.

ヒンジカバー４には開口が設けられており、冷蔵庫本体５０の周辺の大気は、この開口からヒンジカバー４内に入る。これにより、ヒンジカバー４に覆われたヒンジアッセンブリ２に取り付けられた湿度センサ３２により、冷蔵庫回りの大気の湿度を検出できる。 The hinge cover 4 is provided with an opening, and air around the refrigerator main body 50 enters the hinge cover 4 through this opening. Accordingly, the humidity sensor 32 attached to the hinge assembly 2 covered with the hinge cover 4 can detect the humidity of the atmosphere around the refrigerator.

近年、冷蔵庫とインタネーットを繋げたり、スマートフォンをはじめとする電子装置で冷蔵庫を操作したり、冷蔵庫の内部状態をチェックするといった要望が高まっている。このような要望に対応するため、本実施形態では、ヒンジアッセンブリ２’に、ＷＩＦＩ通信ユニット３４が取り付けられている。何れの配線３６を伴う電子機器３０，３２，３４も、ヒンジ係合部材２０の上面に取り付けられているので、配線を伴う電子機器がヒンジカバーに取り付けられている場合に比べて、配線３６が垂れ下がることがないので、取り付け作業を容易に行うことができる。 In recent years, there has been an increasing demand for connecting a refrigerator to the Internet, operating the refrigerator with an electronic device such as a smartphone, and checking the internal state of the refrigerator. In order to meet such a demand, a WIFI communication unit 34 is attached to the hinge assembly 2' in this embodiment. Since the electronic devices 30, 32, and 34 with any wiring 36 are attached to the upper surface of the hinge engaging member 20, the wiring 36 is less likely to be attached than the electronic devices with wiring attached to the hinge cover. Since it does not hang down, it can be easily installed.

以上のように、左側のヒンジアッセンブリ２’の基本的な構造は、右側のヒンジアッセンブリ２の構造と同様である。よって以下では、右側のヒンジアッセンブリ２を例に取って、ヒンジアッセンブリ２，２’に関する詳細な説明を行う。 As described above, the basic structure of the left hinge assembly 2' is similar to that of the right hinge assembly 2.

はじめに、ヒンジアッセンブリ２を組み立てる工程の詳細な説明を行う。図４Ａ、図４Ｂ及び図５の何れも、冷蔵庫本体５０の上面５０Ａに取り付けたとき、冷蔵庫本体５０の上面５０Ａと面する下面側が上向きになるように示されている。 First, a detailed description of the process of assembling the hinge assembly 2 will be given. 4A, 4B, and 5, when attached to the upper surface 50A of the refrigerator main body 50, the lower surface side facing the upper surface 50A of the refrigerator main body 50 is shown facing upward.

本実施形態に係るヒンジ係合部材２０は、ヒンジ部材１０と係合する係合部として、第１のフック部２２及び第２のフック部２４を備える。第１のフック部２２は、凸部２２Ａ及び凹部２２Ｂから構成された凹凸形状を有する。第２のフック部２４は、凸部２４Ａ及び凹部２４Ｂから構成された凹凸形状を有する。ここでは、予め、配線３６を伴う電子機器３０，３２，３４が取り付けられたヒンジ係合部材２０をヒンジ部材１０の板状部１２に係合させるところを説明する。 The hinge engaging member 20 according to this embodiment includes a first hook portion 22 and a second hook portion 24 as engaging portions that engage with the hinge member 10 . The first hook portion 22 has an uneven shape composed of a convex portion 22A and a concave portion 22B. The second hook portion 24 has an uneven shape composed of a convex portion 24A and a concave portion 24B. Here, the manner in which the hinge engaging member 20 to which the electronic devices 30, 32, 34 with the wiring 36 are attached in advance is engaged with the plate-like portion 12 of the hinge member 10 will be described.

［第１の工程］
はじめに、図４Ａの一点鎖線の矢印に示すように、ヒンジ部材１０のヒンジ１４が配置された端部と反対側の端部の両側に設けられた第１の挿入部１２Ａを、ヒンジ係合部材２０の第１のフック部２２の凸部２２Ａをかわして、凹部２２Ｂに斜めに差し込む。 [First step]
First, as shown by the dashed-dotted arrows in FIG. 4A, the first insertion portions 12A provided on both sides of the end of the hinge member 10 opposite to the end where the hinge 14 is arranged are inserted into the hinge engaging member. The projection 22A of the first hook portion 22 of 20 is dodged and is obliquely inserted into the recess 22B.

［第２の工程］
次に、図４Ａの二点鎖線の矢印に示すように、ヒンジ係合部材２０の第１のフック部２２と係合した第１の挿入部１２Ａを回転中心として、ヒンジ１４が配置された側の端部をヒンジ係合部材２０に近づく方向に回転させる。 [Second step]
Next, as shown by the two-dot chain line arrow in FIG. 4A , the side on which the hinge 14 is arranged is rotated around the first insertion portion 12A engaged with the first hook portion 22 of the hinge engagement member 20. is rotated toward the hinge engaging member 20 .

ヒンジ部材１０を回転させていくと、ヒンジ部材１０の板状部１２の第２の挿入部１２Ｂが、ヒンジ係合部材２０の第２のフック部２４の凸部２４Ａに当接する。更に、ヒンジ部材１０を同じ回転方向に押し込むと、ヒンジ係合部材２０が弾性変形し、板状部１２の第２の挿入部１２Ｂが第２のフック部２４の凸部２４Ａを乗り越えて、第２のフック部２４の凹部２４Ｂに入る。これにより、板状部１２の第２の挿入部１２Ｂが、ヒンジ係合部材２０の第２のフック部２４に係合した状態となる。このように、ヒンジ係合部材２０に設けられた係合部である第１及び第２のフック部２２，２４により、スナップ機構が形成されている。 As the hinge member 10 is rotated, the second insertion portion 12B of the plate-like portion 12 of the hinge member 10 comes into contact with the convex portion 24A of the second hook portion 24 of the hinge engagement member 20 . Further, when the hinge member 10 is pushed in the same rotational direction, the hinge engagement member 20 is elastically deformed, and the second insertion portion 12B of the plate-like portion 12 climbs over the projection 24A of the second hook portion 24, 2 enters the concave portion 24B of the hook portion 24 of FIG. As a result, the second insertion portion 12B of the plate-like portion 12 is engaged with the second hook portion 24 of the hinge engagement member 20 . Thus, a snap mechanism is formed by the first and second hook portions 22 and 24, which are the engaging portions provided on the hinge engaging member 20. As shown in FIG.

このようなスナップ機構により、簡易に板状部１２とヒンジ係合部材２０とを係合させることができるので、少ない作業時間で容易にヒンジアッセンブリ２を組み立てることができる。それととともに、凹凸形状との嵌合により、ヒンジ部材１０及びヒンジ係合部材２０の係合状態を確実に維持することができる。 With such a snap mechanism, the plate-like portion 12 and the hinge engaging member 20 can be easily engaged, so that the hinge assembly 2 can be easily assembled in a short working time. At the same time, the engaging state of the hinge member 10 and the hinge engaging member 20 can be reliably maintained by fitting with the concave-convex shape.

このようにして組み立てられたヒンジアッセンブリ２の外形を、図５に示す。矢印Ｓで示すヒンジ部材１０の板状部１２の下面が、冷蔵庫本体５０の上面５０Ａと接する接触固定面となる。板状部１２の下面に設けられた３つの貫通孔１２Ｃにネジ等の締結部材４０を通して、冷蔵庫本体５０に固定する。板状部１２に設けられた第１、第２の挿入部１２Ａ，１２Ｂは、冷蔵庫本体５０に取り付けられた状態において、矢印Ｓで示す接触固定面よりも所定の距離だけ上側に位置している。これにより、ヒンジアッセンブリ２が冷蔵庫本体５０に取り付けられた状態において、第１、第２の挿入部１２Ａ，１２Ｂの下側に位置する第１、第２のフック部２２，２４の凸部２２Ａ，２４Ａの配置スペースを確保している。 FIG. 5 shows the outline of the hinge assembly 2 assembled in this manner. A lower surface of plate-like portion 12 of hinge member 10 indicated by arrow S serves as a contact fixing surface that contacts upper surface 50A of refrigerator body 50 . Fastening members 40 such as screws are passed through three through holes 12</b>C provided on the lower surface of the plate-like portion 12 , and fixed to the refrigerator main body 50 . The first and second insertion portions 12A and 12B provided in the plate-like portion 12 are located above the contact fixing surface indicated by the arrow S by a predetermined distance when attached to the refrigerator body 50. . As a result, when the hinge assembly 2 is attached to the refrigerator main body 50, the projections 22A, 22A, 22A of the first and second hook portions 22, 24 located below the first and second insertion portions 12A, 12B are arranged. 24A placement space is secured.

上記の説明では、配線３６を伴う電子機器３０，３２，３４が取り付けられたヒンジ係合部材２０を、ヒンジ部材１０の板状部１２に係合させるところを説明したが、これに限られるものではない。はじめに、ヒンジ係合部材２０を板状部１２に係合させた後、配線３６を伴う電子機器３０，３２，３４をヒンジ係合部材２０に取り付けることもできる。 In the above description, the hinge engaging member 20, to which the electronic devices 30, 32, 34 with the wiring 36 are attached, is engaged with the plate-like portion 12 of the hinge member 10, but the present invention is limited to this. is not. It is also possible to attach the electronic devices 30 , 32 , 34 with the wiring 36 to the hinge engagement member 20 after first engaging the hinge engagement member 20 with the plate-like portion 12 .

（ヒンジアッセンブリの冷蔵庫本体への取り付け）
図６Ａは、組み立てられたヒンジアッセンブリ２を冷蔵庫本体５０に取り付けるところを示す斜視図である。図６Ｂは、冷蔵庫本体５０に載置されたヒンジアッセンブリ２を締結部材４０で固定するところを示す斜視図である。次に、上記のような第１及び第２の工程で組み立てられたヒンジアッセンブリ２を、冷蔵庫本体５０の上面５０Ａに取り付けるところを説明する。 (Attaching the hinge assembly to the refrigerator body)
FIG. 6A is a perspective view showing how the assembled hinge assembly 2 is attached to the refrigerator body 50. FIG. FIG. 6B is a perspective view showing that the hinge assembly 2 placed on the refrigerator body 50 is fixed with the fastening member 40. FIG. Next, the attachment of the hinge assembly 2 assembled in the first and second steps as described above to the upper surface 50A of the refrigerator main body 50 will be described.

組み立てられたヒンジアッセンブリ２を、冷蔵庫本体５０の上面５０Ａの右前側に載置し、冷蔵庫本体５０側に設けられたネジ孔５４と、ヒンジアッセンブリ２を構成するヒンジ部材１０の板状部１２に設けられた貫通孔１２Ｃ（図５参照）との位置を合わせる。そして、３本の締結部材４０を、板状部１２に設けられたネジ孔１２Ｃに通して、冷蔵庫本体５０に設けられたネジ孔５４と締結する。これにより、ヒンジ部材１０を冷蔵庫本体５０に固定することができ、延いては、ヒンジアッセンブリ２全体を冷蔵庫本体５０に固定できる。 The assembled hinge assembly 2 is placed on the right front side of the upper surface 50A of the refrigerator body 50, and screw holes 54 provided on the refrigerator body 50 side and the plate-like portion 12 of the hinge member 10 constituting the hinge assembly 2 are mounted. It is aligned with the provided through hole 12C (see FIG. 5). Then, the three fastening members 40 are passed through the screw holes 12</b>C provided in the plate-like portion 12 and fastened to the screw holes 54 provided in the refrigerator main body 50 . Thereby, the hinge member 10 can be fixed to the refrigerator main body 50 , and by extension, the entire hinge assembly 2 can be fixed to the refrigerator main body 50 .

金属製のヒンジ部材１０が冷蔵庫本体５０に接して固定されているので、ヒンジ部材１０を高い強度、高い位置精度で冷蔵庫本体５０に固定することができる。ただし、これに限られるものではなく、ヒンジ部材１０及び冷蔵庫本体５０の間に金属等の剛性の高い板状部材を挿入して、ヒンジ部材１０及び冷蔵庫本体５０を固定することもあり得る。 Since the metal hinge member 10 is fixed in contact with the refrigerator main body 50, the hinge member 10 can be fixed to the refrigerator main body 50 with high strength and high positional accuracy. However, the hinge member 10 and the refrigerator main body 50 may be fixed by inserting a highly rigid plate-like member such as metal between the hinge member 10 and the refrigerator main body 50 .

ヒンジアッセンブリ２を冷蔵庫本体５０に取り付けるとき、予め、配線３６を伴う電子機器３０，３２，３４が取り付けられたヒンジ係合部材２０とヒンジ部材１０とを係合した一体的なヒンジアッセンブリ２を取り扱うので、容易に位置決めをして取り付けることができる。特に、配線３６を伴う電子機器３０，３２，３４は、ヒンジ係合部材２０の上面に取り付けられているので、ヒンジカバー４の内側に取り付けられた場合と異なり、配線３６が垂れ下がって干渉することがない。よって、少ない作業時間で、ヒンジ部材１０及び配線３６を伴う電子機器３０，３２，３４を同時に冷蔵庫本体５０の上面に取り付けことができる。 When attaching the hinge assembly 2 to the refrigerator main body 50, the integrated hinge assembly 2 is handled in which the hinge member 10 and the hinge engaging member 20 to which the electronic devices 30, 32, 34 with the wiring 36 are attached in advance are engaged. Therefore, it can be easily positioned and installed. In particular, since the electronic devices 30, 32, 34 with the wires 36 are attached to the upper surface of the hinge engaging member 20, unlike the case where they are attached inside the hinge cover 4, the wires 36 do not hang down and interfere. There is no Therefore, the electronic devices 30, 32, 34 together with the hinge member 10 and the wiring 36 can be attached to the upper surface of the refrigerator main body 50 at the same time in a short work time.

その後、ヒンジアッセンブリ２を覆うようにヒンジカバー４を取り付ける。ヒンジカバー４には、電子機器等は取り付けられていなので、容易に取り付けことができる。また、仮にヒンジカバー４が浮き上がることがあったとしても、ドアスイッチ基板３０をはじめとする電子機器の設置位置は保持される。 After that, the hinge cover 4 is attached so as to cover the hinge assembly 2. - 特許庁Since no electronic device or the like is attached to the hinge cover 4, it can be easily attached. Further, even if the hinge cover 4 were to be lifted, the installation positions of the electronic devices including the door switch board 30 are maintained.

（ヒンジアッセンブリの固定構造）
図７は、ヒンジアッセンブリ２が冷蔵庫本体５０に取り付けられた状態において、ヒンジ係合部材２０の設置位置が保持される機能を説明する図である。次に、図７を参照しながら、ヒンジアッセンブリ２の固定構造を説明する。 (Fixation structure of hinge assembly)
7A and 7B are diagrams illustrating the function of holding the installation position of the hinge engaging member 20 when the hinge assembly 2 is attached to the refrigerator main body 50. FIG. Next, the fixing structure of the hinge assembly 2 will be described with reference to FIG.

ヒンジ係合部材２０の一部であるヒンジ係合部材２０の第１、第２のフック部２２，２４の凸部２２Ａ，２４Ａが、板状部１２の挿入部１２Ａ，１２Ｂと冷蔵庫本体５０との間に配置されている。更に、このようなヒンジ係合部材２０の一部が板状部１２と冷蔵庫本体５０との間に配置されている領域と異なる領域（矢印Ｓ参照）で、間にヒンジ係合部材２０を介さずに、板状部１２が冷蔵庫本体５０に接した状態で固定されている。 The projections 22A and 24A of the first and second hook portions 22 and 24 of the hinge engagement member 20, which is a part of the hinge engagement member 20, are connected to the insertion portions 12A and 12B of the plate-like portion 12 and the refrigerator main body 50. is placed between. Furthermore, in a region (see arrow S) different from the region where a part of the hinge engaging member 20 is arranged between the plate-like portion 12 and the refrigerator main body 50, the hinge engaging member 20 is interposed therebetween. However, the plate-like portion 12 is fixed in contact with the refrigerator body 50 .

金属に比べて強度が低い樹脂部材を介することなく、金属製の板状部１２が冷蔵庫本体５０に接して固定されているので、高い剛性及び高い位置精度を有するヒンジ１４が得られる。これとともに、その他の領域でヒンジ係合部材２０の一部（例えば、凸部２２Ａ，２４Ａ）が板状部１２と冷蔵庫本体５０との間に配置されているので、ヒンジ係合部材２０も確実に保持することができる。 Since the plate-like portion 12 made of metal is fixed in contact with the refrigerator main body 50 without using a resin member having a lower strength than metal, the hinge 14 having high rigidity and high positional accuracy can be obtained. Along with this, part of the hinge engagement member 20 (for example, the convex portions 22A and 24A) is arranged between the plate-like portion 12 and the refrigerator main body 50 in other regions, so that the hinge engagement member 20 is also secured. can be held.

特に、上記の実施形態では、ヒンジアッセンブリ２が、係合部として凹凸形状を有するフック部２２，２４を備え、板状部１２が冷蔵庫本体５０に固定されたとき、板状部１２がフック部２２，２４の凹部２２Ｂ，２４Ｂに配置され、フック部２２，２４の凸部２２Ａ，２４Ａが凹部２２Ｂ，２４Ｂに配置された板状部１２と冷蔵庫本体５０との間に配置されている。 In particular, in the above-described embodiment, the hinge assembly 2 includes hook portions 22 and 24 having uneven shapes as engaging portions, and when the plate-like portion 12 is fixed to the refrigerator main body 50, the plate-like portion 12 engages with the hook portions. The protrusions 22A and 24A of the hook portions 22 and 24 are arranged between the plate-like portion 12 and the refrigerator body 50 arranged in the recesses 22B and 24B.

ヒンジアッセンブリ２は冷蔵庫本体５０に取り付けられた状態で、板状部１２の挿入部１２Ａ，１２Ｂが、矢印Ｓで示す板状部１２の冷蔵庫本体５０と接する面よりも、ヒンジ係合部材２０の凸部２２Ａ，２４Ａの厚み（高さ寸法）に応じた距離だけ上方に形成されている。これにより、板状部１２の挿入部１２Ａ，１２Ｂの下側に位置する凸部２２Ａ，２４Ａの下面が、冷蔵庫本体５０の上面５０Ａとほぼ接するように配置されている。ただし、これに限られるものではなく、締結部材４０を締め込んで、板状部１２を冷蔵庫本体５０に固定したとき、上に位置する挿入部１２Ａ，１２Ｂ及び下に位置する冷蔵庫本体５０に押されて、ヒンジ係合部材２０の凸部２２Ａ，２４Ａが少し圧縮変形するようにすることもできる。この場合には、ヒンジ係合部材２０の位置を更に強固に維持できる。 When the hinge assembly 2 is attached to the refrigerator main body 50, the insertion portions 12A and 12B of the plate-like portion 12 are positioned closer to the hinge engaging member 20 than the surface of the plate-like portion 12 in contact with the refrigerator main body 50 indicated by the arrow S. It is formed upward by a distance corresponding to the thickness (height dimension) of the projections 22A and 24A. As a result, the lower surfaces of the convex portions 22A and 24A located below the insertion portions 12A and 12B of the plate-like portion 12 are arranged so as to be substantially in contact with the upper surface 50A of the refrigerator main body 50 . However, it is not limited to this, and when the fastening member 40 is tightened to fix the plate-like portion 12 to the refrigerator main body 50, the insertion portions 12A and 12B positioned above and the refrigerator main body 50 positioned below are pressed. As a result, the protrusions 22A and 24A of the hinge engagement member 20 can be slightly compressed and deformed. In this case, the position of the hinge engagement member 20 can be maintained more firmly.

上記の実施形態では、スナップ機構でヒンジ部材１０とヒンジ係合部材２０とが係合するので、ヒンジアッセンブリ２が冷蔵庫本体５０に取り付けられた後、組み立て時と逆の手順で両者の係合が解除されて、ヒンジ係合部材２０が冷蔵庫本体５０から外れることを考慮する必要がある。 In the above-described embodiment, the hinge member 10 and the hinge engaging member 20 are engaged with each other by the snap mechanism. Therefore, after the hinge assembly 2 is attached to the refrigerator body 50, the engagement between the two is performed in the reverse order of the assembly procedure. It is necessary to consider that the hinge engaging member 20 is released from the refrigerator main body 50 when it is released.

しかし、図７の矢印Ｆ、Ｆ’に示すように、挿入部１２Ａまたは挿入部１２Ｂが、第１のフック部２２の凸部２２Ａまたは第２のフック部２４の凸部２４Ａを乗り越えるように、ヒンジ係合部材２０に力を加えた場合、冷蔵庫本体５０から矢印Ｒ，Ｒ’に示すような反力を受けるので、ヒンジ係合部材２０を外れる方向には回転が規制されている。 However, as shown by arrows F and F' in FIG. When a force is applied to the hinge engagement member 20, it receives reaction forces indicated by arrows R and R' from the refrigerator main body 50, so the rotation in the direction away from the hinge engagement member 20 is restricted.

以上のように、凹凸形状を有するフック部２２，２４により、ヒンジアッセンブリ２を冷蔵庫本体５０に取り付けたとき、ヒンジ係合部材２０を確実に冷蔵庫本体５０上に保持することができる。 As described above, when the hinge assembly 2 is attached to the refrigerator main body 50 , the hinge engaging member 20 can be reliably held on the refrigerator main body 50 by the hook portions 22 and 24 having the uneven shapes.

上記の実施形態では、ヒンジアッセンブリ２が係合部として凹凸形状を有するフック部２２，２４を備えているが、係合部はこれに限られるものではない。ヒンジアッセンブリ２が冷蔵庫本体５０に取り付けられたとき、板状部１２が冷蔵庫本体５０に固定され、ヒンジ係合部材２０の一部が板状部１２と冷蔵庫本体５０との間に配置されている構造であれば、その他の任意の構造を有する係合部を採用することができる。例えば、着脱可能な部材や締結部材を用いて、板状部１２とヒンジ係合部材２０とを係合させる係合部もあり得る。 In the above-described embodiment, the hinge assembly 2 has hook portions 22 and 24 having uneven shapes as engaging portions, but the engaging portions are not limited to this. When the hinge assembly 2 is attached to the refrigerator main body 50 , the plate-like portion 12 is fixed to the refrigerator main body 50 and part of the hinge engaging member 20 is arranged between the plate-like portion 12 and the refrigerator main body 50 . As long as it has a structure, an engaging portion having any other structure can be adopted. For example, there may be an engaging portion that engages the plate-like portion 12 and the hinge engaging member 20 using a detachable member or a fastening member.

また、上記の実施形態では、ヒンジアッセンブリ２が冷蔵庫本体５０の上面５０Ａに取り付けられる場合を示すが、これに限られるものではない。例えば、ヒンジアッセンブリ２が冷蔵庫本体５０の下面や側面に取り付けられる場合もあり得る。何れの場合でも、ヒンジアッセンブリ２を冷蔵庫本体５０に取り付けるとき、配線３６が垂れ下がることがないように、配線３６を伴う電子機器３０，３２，３４は、ヒンジアッセンブリ２が冷蔵庫本体５０に取り付けられる状態での上面に配置される。 Also, in the above embodiment, the case where the hinge assembly 2 is attached to the upper surface 50A of the refrigerator main body 50 is shown, but the present invention is not limited to this. For example, the hinge assembly 2 may be attached to the bottom surface or side surface of the refrigerator body 50 . In any case, when the hinge assembly 2 is attached to the refrigerator body 50 , the electronic devices 30 , 32 , 34 with the wiring 36 are positioned so that the wiring 36 does not hang down when the hinge assembly 2 is attached to the refrigerator body 50 . placed on top of the

以上を考慮したヒンジアッセンブリ２は、冷蔵庫本体５０に取り付けられるアッセンブリであって、板状部１２及び板状部１２から立設したヒンジ１４を有する金属製のヒンジ部材１０と、板状部１２と係合する係合部を有する樹脂製のヒンジ係合部材２０と、ヒンジ係合部材２０の上面に取り付けられた、ドアスイッチ基板３０を少なくとも含む、配線３６を伴う電子機器３０，３２，３４と、を備え、冷蔵庫本体５０に取り付けられたとき、板状部１４が冷蔵庫本体５０に固定され、ヒンジ係合部材２０の一部が板状部１４と冷蔵庫本体５０との間に配置されている。 The hinge assembly 2 in consideration of the above is an assembly to be attached to the refrigerator body 50, and includes the metal hinge member 10 having the plate-like portion 12 and the hinge 14 erected from the plate-like portion 12, and the plate-like portion 12. A hinge engaging member 20 made of resin having an engaging portion to be engaged, and electronic devices 30, 32, 34 attached to the upper surface of the hinge engaging member 20 and including at least a door switch board 30 and accompanied by wiring 36. , and when attached to the refrigerator body 50, the plate-like portion 14 is fixed to the refrigerator body 50, and a part of the hinge engaging member 20 is arranged between the plate-like portion 14 and the refrigerator body 50. .

このようなヒンジアッセンブリ２では、上面に配線３６を伴う電子機器３０，３２，３４が取り付けられたヒンジ係合部材２０とヒンジ部材１０とが一体となったアッセンブリ２を、冷蔵庫本体５０に取り付けるので、一度の取り付け作業で、ヒンジ１４も電子機器３０，３２，３４も同時に冷蔵庫本体５０に取り付けることができる。また、取り付け時に配線３６が垂れ下がることもないので、少ない作業時間で容易にヒンジアッセンブリ２を冷蔵庫本体５０に取り付けることができる。 In such a hinge assembly 2, the assembly 2 in which the hinge member 10 and the hinge engaging member 20, to which the electronic devices 30, 32, 34 with the wiring 36 are attached on the upper surface, and the hinge member 10 are integrated, is attached to the refrigerator main body 50. , the hinge 14 and the electronic devices 30, 32, 34 can be attached to the refrigerator main body 50 at the same time by one attachment operation. In addition, since the wiring 36 does not hang down during attachment, the hinge assembly 2 can be easily attached to the refrigerator main body 50 in a short working time.

更に、ヒンジアッセンブリ２が冷蔵庫本体５０に取り付けられたとき、強度を有する板状部１２が冷蔵庫本体５０に固定され、ヒンジ係合部材２０の一部が板状部１２と冷蔵庫本体５０との間に配置されているので、ヒンジ係合部材２０も板状部１２に保持されて浮き上がることがない。これにより、ヒンジ係合部材２０に取り付けられた電子機器３０，３２，３４の位置も確実に保持できる。 Furthermore, when the hinge assembly 2 is attached to the refrigerator main body 50 , the plate-like portion 12 having strength is fixed to the refrigerator main body 50 , and a portion of the hinge engaging member 20 is positioned between the plate-like portion 12 and the refrigerator main body 50 . Therefore, the hinge engaging member 20 is also held by the plate-like portion 12 and does not float. Thereby, the positions of the electronic devices 30, 32, 34 attached to the hinge engaging member 20 can also be reliably held.

以上により、ヒンジ１４及びヒンジの周囲に配置される電子機器３０，３２，３４を少ない作業時間で容易に冷蔵庫本体５０に取り付けることができるとともに、取り付けられたドアスイッチ基板３０を含む電子機器３０，３２，３４の位置を確実に保持することができるヒンジアッセンブリ２を提供することができる。 As described above, the hinge 14 and the electronic devices 30, 32, 34 arranged around the hinge can be easily attached to the refrigerator main body 50 in a short work time, and the electronic device 30 including the attached door switch board 30 can be installed. It is possible to provide a hinge assembly 2 that can reliably hold the positions of 32,34.
