上記ヒンジ保持部材３と上記ヒンジピン４は、上記ヒンジピン４が上記扉２の上記取付孔２０に差し込まれた状態で、上記ヒンジピン４の軸Ｌ回り方向に相互に位置決めされている。具体的に述べると、上記ヒンジピン４の先端部は、Dカット加工を施され、上記扉２の上記取付孔２０は、上記ヒンジピン４の先端部に対応する形状に形成されている。このように、簡単な構成で、上記ヒンジピン４と上記取付孔２０とを嵌合することができる。   The hinge holding member 3 and the hinge pin 4 are positioned relative to each other in the direction around the axis L of the hinge pin 4 in a state where the hinge pin 4 is inserted into the mounting hole 20 of the door 2. Specifically, the tip of the hinge pin 4 is subjected to D-cut processing, and the mounting hole 20 of the door 2 is formed in a shape corresponding to the tip of the hinge pin 4. Thus, the hinge pin 4 and the mounting hole 20 can be fitted with a simple configuration.

図３Ａ、図３Ｂおよび図３Ｃに示すように、上記ヒンジ保持部材３は、保持係止部３１を有し、上記ヒンジピン４は、ピン係止部４１を有する。なお、図３Ｂは、上記ヒンジピン４が、図３Ａの実線にて示す状態にある（第１位置）ときの正面図を示す。図３Ｃは、上記ヒンジピン４が、図３Ａの仮想線にて示す状態にある（第２位置）ときの側面図を示す。   As shown in FIGS. 3A, 3B, and 3C, the hinge holding member 3 has a holding locking portion 31, and the hinge pin 4 has a pin locking portion 41. FIG. 3B shows a front view when the hinge pin 4 is in the state shown by the solid line in FIG. 3A (first position). FIG. 3C shows a side view when the hinge pin 4 is in a state indicated by a virtual line in FIG. 3A (second position).

そして、図１および図３Ｂに示すように、上記扉２の上記冷蔵庫本体１に対する閉状態では、上記ピン係止部４１は、上記ヒンジピン４の軸Ｌ方向からみて、上記保持係止部３１に重ならない。一方、図３Ｃに示すように、上記扉２の上記冷蔵庫本体１に対する開状態では、上記ピン係止部４１は、上記ヒンジピン４の軸Ｌ方向からみて、上記保持係止部３１の下側に重なる。   1 and 3B, in the closed state of the door 2 with respect to the refrigerator body 1, the pin locking portion 41 is connected to the holding locking portion 31 when viewed from the axis L direction of the hinge pin 4. Do not overlap. On the other hand, as shown in FIG. 3C, in the opened state of the door 2 with respect to the refrigerator main body 1, the pin locking portion 41 is located below the holding locking portion 31 when viewed from the axis L direction of the hinge pin 4. Overlap.

具体的に述べると、上記ピン係止部４１は、上記ヒンジピン４の軸Ｌ方向からみて略Ｄ形の鍔状に形成されている。上記保持係止部３１は、上記ヒンジ保持部材３の本体から上方に延びて内側に折り曲げられて形成された部分である。   Specifically, the pin locking portion 41 is formed in a substantially D-shaped bowl shape when viewed from the axis L direction of the hinge pin 4. The holding locking portion 31 is a portion that extends upward from the main body of the hinge holding member 3 and is bent inward.

そして、上記扉２の閉状態では、図３Ａ中の実線と図３Ｂに示すように、上記ピン係止部４１は、上記保持係止部３１の下側に位置すると共に上記保持係止部３１に重ならない。したがって、上記ヒンジピン４を上記ヒンジ保持部材３から上記ヒンジピン４の軸Ｌ方向に沿って上側へ抜き取ることができる。   In the closed state of the door 2, as shown in the solid line in FIG. 3A and FIG. 3B, the pin locking portion 41 is positioned below the holding locking portion 31 and the holding locking portion 31. Does not overlap. Therefore, the hinge pin 4 can be extracted upward from the hinge holding member 3 along the axis L direction of the hinge pin 4.

一方、上記扉２の開状態では、上記扉２の回転に追従（連動）して、上記ヒンジピン４が、上記ヒンジピン４の軸Ｌ回りに回転して、図３Ａ中の仮想線と図３Ｃに示すように、上記ピン係止部４１は、上記保持係止部３１の下側に重なる。したがって、上記ヒンジピン４を上記ヒンジピン４の軸Ｌ方向に沿って上側へ移動させると、上記ピン係止部４１が上記保持係止部３１に接触して、上記ヒンジピン４は上記ヒンジ保持部材３から抜け止めされる。このように、上記扉２の開状態では、上記ヒンジピン４は、上記ヒンジ保持部材３から抜き取ることができない。   On the other hand, in the opened state of the door 2, the hinge pin 4 rotates around the axis L of the hinge pin 4 following (interlocking) with the rotation of the door 2, and the phantom line in FIG. 3A and FIG. As shown, the pin locking part 41 overlaps the lower side of the holding locking part 31. Accordingly, when the hinge pin 4 is moved upward along the direction of the axis L of the hinge pin 4, the pin locking portion 41 comes into contact with the holding locking portion 31, and the hinge pin 4 is moved from the hinge holding member 3. It is prevented from coming off. Thus, when the door 2 is in the open state, the hinge pin 4 cannot be removed from the hinge holding member 3.

図１に示すように、上記カバー部材５は、左右の上記ヒンジ保持部材３，３を同時に覆うように、左右方向に長尺に形成されている。上記カバー部材５は、弾性変形して、上記冷蔵庫本体１の上部の前縁部に着脱される。   As shown in FIG. 1, the cover member 5 is formed long in the left-right direction so as to simultaneously cover the left and right hinge holding members 3, 3. The cover member 5 is elastically deformed and is attached to and detached from the front edge of the upper portion of the refrigerator body 1.

上記ヒンジピン４が上記取付孔２０に差し込まれて上記ピン係止部４１が上記保持係止部３１の下側に位置すると共に上記カバー部材５が上記冷蔵庫本体１に取り付けられた状態で、上記カバー部材５は、内側に、上記ヒンジピン４の上方の近傍に位置する抑止部５１を有する。   The hinge pin 4 is inserted into the mounting hole 20, the pin locking portion 41 is positioned below the holding locking portion 31, and the cover member 5 is mounted to the refrigerator body 1, The member 5 has a restraining portion 51 located in the vicinity above the hinge pin 4 on the inner side.

そして、上記ヒンジピン４が上記取付孔２０に確実に差し込まれた状態では、上記抑止部５１にて上記ヒンジピン４の上記取付孔２０からの抜けを防止することができる。一方、上記ヒンジピン４が上記取付孔２０に確実に差し込まれていない状態では、上記抑止部５１が、上記ヒンジピン４の上方に当接して、上記カバー部材５を上記冷蔵庫本体１に取り付けることができず、上記ヒンジピン４が上記取付孔２０に確実に差し込まれているか否かを、容易に判断することができる。   In a state where the hinge pin 4 is securely inserted into the mounting hole 20, the restraining portion 51 can prevent the hinge pin 4 from coming off from the mounting hole 20. On the other hand, in a state where the hinge pin 4 is not securely inserted into the mounting hole 20, the restraining portion 51 can contact the hinge pin 4 and attach the cover member 5 to the refrigerator body 1. Therefore, it can be easily determined whether or not the hinge pin 4 is securely inserted into the mounting hole 20.

次に、上記扉２を右開きから左開きに変更する場合を説明する。   Next, a case where the door 2 is changed from a right opening to a left opening will be described.

まず、上記カバー部材５を弾性変形させて上記冷蔵庫本体１から取り外す。そして、上記扉２を閉じた状態（すなわち、上記ヒンジピン４の上記ピン係止部４１が、図３Ａの実線に示す位置にあるとき）で、上記扉２の右側の上記取付孔２０、および、右側の上記ヒンジ保持部材３の上記貫通孔３０に差し込まれている上記ヒンジピン４を抜き取る。   First, the cover member 5 is elastically deformed and removed from the refrigerator body 1. And in the state where the door 2 is closed (that is, when the pin locking portion 41 of the hinge pin 4 is at the position shown by the solid line in FIG. 3A), the mounting hole 20 on the right side of the door 2 and The hinge pin 4 inserted into the through hole 30 of the right hinge holding member 3 is removed.

その後、上記扉２を上記冷蔵庫本体１から取り外して、上記ピン部６２を右側の上記支持部材６１から抜き取り、このピン部６２を左側の上記支持部材６１に差し込み、上記扉２の左側の下部の孔部を、上記ピン部６２に差し込ませる。   Thereafter, the door 2 is removed from the refrigerator body 1, the pin portion 62 is extracted from the right support member 61, the pin portion 62 is inserted into the left support member 61, and the lower left portion of the door 2 is The hole portion is inserted into the pin portion 62.

そして、抜き取った上記ヒンジピン４を、左側の上記ヒンジ保持部材３の上記貫通孔３０、および、上記扉２の左側の上記取付孔２０に差し込むことで、上記扉２を左開きに変更することができる。そして、上記カバー部材５を弾性変形させて上記冷蔵庫本体１に再度取り付ける。このように、専用工具を使用せず、容易に上記扉２の左右開きを変更することができる。   Then, by inserting the extracted hinge pin 4 into the through hole 30 of the left hinge holding member 3 and the mounting hole 20 on the left side of the door 2, the door 2 can be changed to open left. it can. Then, the cover member 5 is elastically deformed and attached to the refrigerator body 1 again. In this way, the left and right opening of the door 2 can be easily changed without using a dedicated tool.

そして、上記扉２を左開きにしたとき、左側の上記ヒンジ保持部材３と、上記ヒンジピン４との位置関係は、図３Ａに示す位置関係と対称な位置関係にある。すなわち、上記扉２を開けていくとき、上記扉２が右開きの場合、図３Ａに示すように、上記ピン係止部４１は、上記軸Ｌを中心として反時計回り方向に回転する一方、上記扉２が左開きの場合、上記ピン係止部４１は、上記軸Ｌを中心として時計回り方向に回転する。要するに、上記扉２を左開きにした場合でも、同様に、上記扉２の閉状態では、上記ピン係止部４１は、上記保持係止部３１に重ならない一方、上記扉２の開状態では、上記ピン係止部４１は、上記保持係止部３１の下側に重なる。   When the door 2 is left-opened, the positional relationship between the left hinge holding member 3 and the hinge pin 4 is symmetrical to the positional relationship shown in FIG. 3A. That is, when the door 2 is opened, when the door 2 is opened to the right, the pin locking portion 41 rotates counterclockwise about the axis L as shown in FIG. When the door 2 is opened to the left, the pin locking portion 41 rotates clockwise about the axis L. In short, even when the door 2 is opened to the left, similarly, in the closed state of the door 2, the pin locking portion 41 does not overlap the holding locking portion 31, while in the open state of the door 2. The pin locking part 41 overlaps the lower side of the holding locking part 31.

このように、上記扉２が右開きであれ左開きであれ、上記扉２の開状態では、上記ヒンジピン４は、上記ヒンジ保持部材３から抜き取ることができないので、上記扉２の開状態で上記扉２が落下する危険性がなく、安全性に優れたものになる。   In this way, the hinge pin 4 cannot be removed from the hinge holding member 3 when the door 2 is open, whether the door 2 is opened to the right or left, so that the door 2 is open when the door 2 is open. There is no risk of the door 2 falling, and the door 2 is excellent in safety.

また、上記カバー部材５を備えるので、上記扉２の閉状態で、上記ヒンジピン４を誤って抜き取るおそれがなく、安全性に一層優れたものになる。また、上記カバー部材５は、弾性変形して、上記冷蔵庫本体１から離脱されるので、工具を使わずに、上記カバー部材５を上記冷蔵庫本体１から容易に着脱することができる。   In addition, since the cover member 5 is provided, there is no risk of the hinge pin 4 being accidentally pulled out when the door 2 is closed, and the safety is further improved. Further, since the cover member 5 is elastically deformed and is detached from the refrigerator main body 1, the cover member 5 can be easily detached from the refrigerator main body 1 without using a tool.

また、上記ヒンジピン４のピン係止部４１は、鍔状に形成されているので、上記ピン係止部４１は、指で摘みやすい形状をしており、上記ヒンジピン４を上記取付孔２０へ容易に抜き差しできる。   Further, since the pin locking portion 41 of the hinge pin 4 is formed in a hook shape, the pin locking portion 41 has a shape that can be easily picked by a finger, and the hinge pin 4 can be easily inserted into the mounting hole 20.
