Description

本発明は、冷蔵庫に関する。 The present invention relates to a refrigerator.

冷蔵庫内の貯蔵スペースを有効活用するため、例えば、冷蔵室内を区画するための複数の棚板が上下方向に並設されている。また、同様の目的で、冷蔵室の前面開口を開閉する断熱扉の裏面に、複数の収納ラックが上下方向に並設される。 In order to effectively utilize the storage space in the refrigerator, for example, a plurality of shelves for partitioning the refrigerating room are arranged side by side in the vertical direction. Further, for the same purpose, a plurality of storage racks are arranged side by side in the vertical direction on the back surface of the heat insulating door that opens and closes the front opening of the refrigerator compartment.

ところで、一般の冷蔵庫において、前記棚板や収納ラックの位置は固定されている。これに対して、被貯蔵物は、種類や包装形態によって種々の高さを有する。そのため、棚板や収納ラックの高さ位置が固定されていると、被貯蔵物とその直上に配置された棚板や収納ラックとの間に空域が生じる。この空域は、被貯蔵物を置き得ないデッドスペースとなるため、冷蔵庫内の貯蔵スペースの有効活用が阻害される。このような冷蔵庫内のデッドスペースの解消を想定する技術が、例えば下記特許文献１，２に開示されている。 By the way, in a general refrigerator, the positions of the shelves and storage racks are fixed. On the other hand, the stored object has various heights depending on the type and packaging form. Therefore, if the height position of the shelf board or the storage rack is fixed, an air space is created between the stored object and the shelf board or the storage rack arranged immediately above the stored object. Since this airspace becomes a dead space in which the stored object cannot be placed, the effective utilization of the storage space in the refrigerator is hindered. Techniques for eliminating such a dead space in a refrigerator are disclosed in, for example, Patent Documents 1 and 2 below.

特開２０１０－７１５７７号公報Japanese Unexamined Patent Publication No. 2010-71577 特開２００５－４３０４８号公報Japanese Unexamined Patent Publication No. 2005-43048

しかしながら、前記特許文献に開示の技術は、いずれも冷蔵室内の棚板の高さ位置を調節するものであって、断熱扉の裏面に設けられる収納ラックの高さ位置を調節するものではない。収納ラックにも、種々の高さを有する被貯蔵物（例えば、飲料や液体調味料等を充填したボトル類など）が収納されるため、前記のデッドスペースの問題が同じく生じ得る。 However, all of the techniques disclosed in the above patent documents adjust the height position of the shelf board in the refrigerating room, and do not adjust the height position of the storage rack provided on the back surface of the heat insulating door. Since the storage rack also stores objects to be stored having various heights (for example, bottles filled with beverages, liquid seasonings, etc.), the above-mentioned dead space problem may occur as well.

前記課題に鑑み、本発明は、被貯蔵物の貯蔵（収納）スペースの更なる有効活用を図るため、断熱扉の裏面において、高さ位置を調節可能な収納ラックを備える冷蔵庫の提供を目的とする。 In view of the above problems, it is an object of the present invention to provide a refrigerator provided with a storage rack whose height position can be adjusted on the back surface of the heat insulating door in order to further effectively utilize the storage (storage) space for the stored object. do.

A plurality of second concave portions that can be engaged with the second convex portion are sequentially arranged side by side in the height direction of the second side wall in the rail groove.
The storage rack is moved up and down along the rail groove into which the rib is fitted so that the first convex portion reaches a height position of any of the first concave portions and the second convex portion is the second convex portion. By reaching the height position of any of the two concave portions, the first convex portion and the first concave portion are engaged with each other, and the second convex portion and the second concave portion are engaged with each other to accommodate the storage. It is characterized in that the rack is fixed at a predetermined height position.

本発明によれば、収納ラックの側壁から外方に突出するリブと、リブを嵌め込んでその上下方向への移動路としての役割を果たすレール溝を備えた収納ラック高さ位置調節部とを設けることで、収納ラックを上下方向に移動させることができる。これにより、収納ラックに収納される被貯蔵物の高さに応じて、収納ラックの高さ位置を適宜調節できるため、デッドスペースが生じる事態を抑制できる。すなわち、収納ラックの高さ位置が常時固定される従来の冷蔵庫に比べて、断熱扉の裏面側に設けられる被貯蔵物の貯蔵スペースを有効に活用できる。また、取付部において、収納ラック高さ位置調節部側に設けられる雄部が、断熱扉裏面の突出壁内部に設けられる雌部に着脱可能に取り付けられるため、収納ラック高さ位置調節部を断熱扉に後付けできる。これにより、既に提供されている冷蔵庫の断熱扉の構造を変更することなく、収納ラック高さ位置調節部を取り付けることができる。すなわち、専用の構造を備えた断熱扉を設けなくても、汎用の断熱扉に収納ラック高さ位置調節部を取り付けることができる。その結果、製品のコスト高騰を招かない。 According to the present invention, a rib that protrudes outward from the side wall of the storage rack and a storage rack height position adjusting portion having a rail groove that is fitted with the rib and serves as a vertical movement path thereof are provided. By providing it, the storage rack can be moved in the vertical direction. As a result, the height position of the storage rack can be appropriately adjusted according to the height of the stored object stored in the storage rack, so that a situation where a dead space is generated can be suppressed. That is, compared to the conventional refrigerator in which the height position of the storage rack is always fixed, the storage space for the stored object provided on the back side of the heat insulating door can be effectively utilized. Further, in the mounting portion, the male portion provided on the storage rack height position adjusting portion side is detachably attached to the female portion provided inside the protruding wall on the back surface of the heat insulating door, so that the storage rack height position adjusting portion is insulated. Can be retrofitted to the door. As a result, the storage rack height position adjusting unit can be attached without changing the structure of the heat insulating door of the refrigerator already provided. That is, the storage rack height position adjusting portion can be attached to the general-purpose heat insulating door without providing the heat insulating door having a dedicated structure. As a result, the cost of the product does not rise.

また、本発明によれば、被収容凸部の係合部が、凹部の拡幅部と係合するため、収納ラック高さ位置調節部をより強固に固定することができる。これにより、収納ラック高さ位置調節部が落下するなどの事態を確実に防ぐことができる。 Further, according to the present invention, since the engaging portion of the convex portion to be accommodated engages with the widening portion of the concave portion, the height position adjusting portion of the storage rack can be fixed more firmly. As a result, it is possible to reliably prevent a situation in which the height position adjusting portion of the storage rack falls.

更に、本発明によれば、収納ラック支持部の基部が、レール溝から断熱扉の幅方向内側に延在し、収納ラックの底壁側を支えるため、所定の高さ位置で収納ラックをより確実に支持することができる。 Further, according to the present invention, the base of the storage rack support portion extends inward in the width direction of the heat insulating door from the rail groove to support the bottom wall side of the storage rack, so that the storage rack can be held at a predetermined height position. Can be reliably supported.

更に、本発明によれば、収納ラックを所定の高さ位置まで移動させた際、リブの第１凸部とレール溝の第１凹部とが係合すると共に、リブの第２凸部とレール溝の第２凹部とが係合することで、収納ラックを固定できる。リブの第１凸部及び第２凸部、並びにレール溝の第１凹部及び第２凹部のようなシンプルな構造によって収納ラックの高さ位置を調節できるため、冷蔵庫の過度なコストアップを防止できる。 Further, according to the present invention, when the storage rack is moved to a predetermined height position, the first convex portion of the rib and the first concave portion of the rail groove are engaged with each other, and the second convex portion of the rib and the rail are engaged. The storage rack can be fixed by engaging with the second recess of the groove. Since the height position of the storage rack can be adjusted by a simple structure such as the first convex portion and the second convex portion of the rib, and the first concave portion and the second concave portion of the rail groove, it is possible to prevent an excessive cost increase of the refrigerator. ..

複数の爪部２２４は、環状部２２３の径方向外側に各々突出すると共に、環状部２２３の外周に沿って並設される。更に、個々の爪部２２４は、径方向外側に向かうに従い爪部２２４の幅を狭めるよう傾斜する傾斜面２２４Ｓ、環状部２２３の外周面から垂直に立ち上がる垂直面２２４Ｖを備える。 The plurality of claw portions 224 project outward in the radial direction of the annular portion 223, and are arranged side by side along the outer periphery of the annular portion 223. Further, each claw portion 224 includes an inclined surface 224S that is inclined so as to narrow the width of the claw portion 224 toward the outside in the radial direction, and a vertical surface 224V that rises vertically from the outer peripheral surface of the annular portion 223.

更に、図４及び図５に示されるように、収納ラック２０の両側壁に凹設される第２凹領域２０Ｓ５，２０Ｓ６の各々に、一対のロックレバー２３が設けられる。本実施形態における各ロックレバー２３は、同じ凹領域に取り付けられる回転体２２の上方に配設され、回転する回転体２２に作用する部材である。 Further, as shown in FIGS. 4 and 5, a pair of lock levers 23 are provided in each of the second concave regions 20S5 and 20S6 recessed in both side walls of the storage rack 20. Each lock lever 23 in the present embodiment is a member that is arranged above the rotating body 22 attached to the same concave region and acts on the rotating rotating body 22.

本実施形態において、前記の第２凹領域２０Ｓ５，２０Ｓ６の上面２０Ｓ５１，２０Ｓ６１は開口する（ただし、図４及び図５には、第２凹領域２０Ｓ６、開口上面２０Ｓ６１のみが図示される。以下、第２凹領域２０Ｓ６とそれに装着されるロックレバー２３の構造を例に説明するが、第２凹領域２０Ｓ５とそれに装着されるロックレバー２３も同様の構造を備える。）。 In the present embodiment, the upper surfaces 20S51 and 20S61 of the second concave regions 20S5 and 20S6 are open (however, in FIGS. 4 and 5, only the second concave regions 20S6 and the open upper surface 20S61 are shown below. The structure of the second concave region 20S6 and the lock lever 23 mounted on the second concave region 20S6 will be described as an example, but the second concave region 20S5 and the lock lever 23 mounted on the second concave region 20S5 also have the same structure).

ロックレバー２３は、その一端側２３１が開口上面２０Ｓ６１の前端部２０Ｓ６２に回転可能に軸支されると共に、他端側２３２が一端側２３１を軸に回動可能な状態で開口上面２０Ｓ６１に収められる（図５参照）。ただし、ロックレバー２３の位置は、これに限られない。 The lock lever 23 is housed in the opening upper surface 20S61 in a state where one end side 231 is rotatably supported by the front end portion 20S62 of the opening upper surface 20S61 and the other end side 232 is rotatable about the one end side 231. (See FIG. 5). However, the position of the lock lever 23 is not limited to this.

更に、図５に示されるように、ロックレバー２３は、他端側２３２の底部から下方に突出し、回転体２２の爪部２２４と衝突する衝突凸部２３３を備える。衝突凸部２３３は、爪部２２４の傾斜面２２４Ｓと衝突する一面２３３Ｓ、一面２３３Ｓの対向面であって、爪部２２４の垂直面２２４Ｖと衝突する他面２３３Ｖを備える。 Further, as shown in FIG. 5, the lock lever 23 includes a collision convex portion 233 that protrudes downward from the bottom portion of the other end side 232 and collides with the claw portion 224 of the rotating body 22. The collision convex portion 233 includes one surface 233S that collides with the inclined surface 224S of the claw portion 224 and one surface 233S facing the other surface 233V that collides with the vertical surface 224V of the claw portion 224.

衝突凸部２３３の一面２３３Ｓは、爪部２２４の傾斜面２２４Ｓに対応するよう傾斜する。また、衝突凸部２３３の他面２３３Ｖは、爪部２２４の垂直面２２４Ｖに対応するよう、ロックレバー２３の底部から下方に向けて垂直に延設（垂設）される。 One surface 233S of the collision convex portion 233 is inclined so as to correspond to the inclined surface 224S of the claw portion 224. Further, the other surface 233V of the collision convex portion 233 is vertically extended (vertically laid) downward from the bottom of the lock lever 23 so as to correspond to the vertical surface 224V of the claw portion 224.

なお、収納ラック２０は、その収納ラック２０の直下に配置される他の収納ラック２０に収納される被貯蔵物の転倒を防ぐ転倒防止リブ２４を備えることが好ましい。本実施形態における転倒防止リブ２４は、図６に示されるように、収納ラック２０の底壁２０Ｂから下方に延設される。転倒防止リブ２４は、被貯蔵物の少なくとも上端前方域や側方域を覆うように延在する。例えば、何らかの衝撃で被貯蔵物が転倒しかかると、その上端と転倒防止リブ２４とが衝突する。これにより、転倒防止リブ２４と被貯蔵物の例えば上端が干渉する結果、被貯蔵物の転倒が防止される。 It is preferable that the storage rack 20 is provided with a fall prevention rib 24 for preventing the stored object to be stored in another storage rack 20 arranged directly under the storage rack 20 from falling. As shown in FIG. 6, the fall prevention rib 24 in the present embodiment extends downward from the bottom wall 20B of the storage rack 20. The fall prevention rib 24 extends so as to cover at least the upper end front region and the lateral region of the stored object. For example, when the stored object is about to fall due to some kind of impact, the upper end thereof collides with the fall prevention rib 24. As a result, the fall prevention rib 24 and, for example, the upper end of the stored object interfere with each other, and as a result, the stored object is prevented from falling.

後述のように、収納ラック２０は、収納ラック高さ位置調節部３０によって上下移動可能に支持される。そのため、上下隣設される収納ラック２０のうち、少なくとも上方側に配置される収納ラック２０は、下方側の収納ラック２０に収納される被貯蔵物の上端近傍まで移動可能である。 As will be described later, the storage rack 20 is supported by the storage rack height position adjusting unit 30 so as to be vertically movable. Therefore, of the storage racks 20 arranged vertically and vertically, at least the storage rack 20 arranged on the upper side can move to the vicinity of the upper end of the stored object stored in the storage rack 20 on the lower side.

すなわち、常時、高さが一定な被貯蔵物が下方側の収納ラック２０に収納されない場合でも、上方側の収納ラック２０の上下移動によって、転倒防止リブ２４を適宜位置に配置できる。これにより、高さ位置が固定される従来の収納ラック２０に転倒防止リブ２４を設ける態様に比べて、被貯蔵物の転倒をより有効に防止できる。 That is, even when the stored object having a constant height is not always stored in the storage rack 20 on the lower side, the fall prevention rib 24 can be appropriately arranged at an appropriate position by moving the storage rack 20 on the upper side up and down. As a result, the fall of the stored object can be prevented more effectively than in the case where the fall prevention rib 24 is provided on the conventional storage rack 20 whose height position is fixed.

次に、図７及び図８を参照して、収納ラック高さ位置調節部３０の構造を詳述する。図７は、収納ラック高さ位置調節部３０の一部を示す部分斜視図である。また、図８は、収納ラック２０を装着した状態の収納ラック高さ位置調節部３０の一部を示す部分図である。 Next, with reference to FIGS. 7 and 8, the structure of the storage rack height position adjusting unit 30 will be described in detail. FIG. 7 is a partial perspective view showing a part of the storage rack height position adjusting unit 30. Further, FIG. 8 is a partial view showing a part of the storage rack height position adjusting unit 30 in a state where the storage rack 20 is mounted.

収納ラック高さ位置調節部３０は、収納ラック２０を上下移動可能に支持し、その高さ位置を調節する機能を有する。より詳しくは、収納ラック高さ位置調節部３０は、その高さ方向に沿って延在するレール溝３１、レール溝３１と略平行に延在するラックギア３２を備える（図７参照）。 The storage rack height position adjusting unit 30 has a function of supporting the storage rack 20 so as to be movable up and down and adjusting the height position thereof. More specifically, the storage rack height position adjusting unit 30 includes a rail groove 31 extending along the height direction thereof and a rack gear 32 extending substantially parallel to the rail groove 31 (see FIG. 7).

本実施形態において、レール溝の第１側壁３１Ｓ１に、各々、前方側へ窪む複数の第１凹部３１１が凹設される。図７に示されるように、複数の第１凹部３１１は、レール溝３１の高さ方向に沿って順次並設される。図示される複数の第１凹部３１１は、等間隔で並べられているが、これに限られない。 In the present embodiment, a plurality of first recesses 311 recessed forward are provided in the first side wall 31S1 of the rail groove, respectively. As shown in FIG. 7, the plurality of first recesses 311 are sequentially arranged side by side along the height direction of the rail groove 31. The plurality of first recesses 311 shown are arranged at equal intervals, but the present invention is not limited to this.

更に、レール溝の第２側壁３１Ｓ２に、各々、背方側へ窪む複数の第２凹部３１２が凹設される。図７に示されるように、複数の第２凹部３１２は、レール溝３１の高さ方向に沿って順次並設される。図示される複数の第２凹部３１２は、等間隔で並べられているが、これに限られない。 Further, a plurality of second recesses 312 recessed in the dorsal side are recessed in the second side wall 31S2 of the rail groove. As shown in FIG. 7, the plurality of second recesses 312 are sequentially arranged side by side along the height direction of the rail groove 31. The plurality of second recesses 312 shown are arranged at equal intervals, but the present invention is not limited to this.

図８に示されるように、レール溝３１は、収納ラック２０のリブ２１より幅広であり、レール溝３１内にリブ２１が嵌め込まれる。この状態で、リブ２１を上下移動させ、その第１凸部２１１が、レール溝３１の第１凹部３１１の位置に至る。これにより、第１凸部２１１と第１凹部３１１とが係合する。同様に、リブ２１の第２凸部２１２が、レール溝３１の第２凹部３１２の位置に至る。これにより、第２凸部２１２と第２凹部３１２とが係合する。その結果、収納ラック２０は、リブ２１を介して、レール溝３１の延在方向（上下方向）に移動可能な状態で、所定の高さ位置で収納ラック位置調節部３０に支持される。 As shown in FIG. 8, the rail groove 31 is wider than the rib 21 of the storage rack 20, and the rib 21 is fitted in the rail groove 31. In this state, the rib 21 is moved up and down, and the first convex portion 211 reaches the position of the first concave portion 311 of the rail groove 31. As a result, the first convex portion 211 and the first concave portion 311 are engaged with each other. Similarly, the second convex portion 212 of the rib 21 reaches the position of the second concave portion 312 of the rail groove 31. As a result, the second convex portion 212 and the second concave portion 312 are engaged with each other. As a result, the storage rack 20 is supported by the storage rack position adjusting portion 30 at a predetermined height position while being movable in the extending direction (vertical direction) of the rail groove 31 via the rib 21.

また、本実施形態における収納ラック高さ位置調節部３０のラックギア３２は、収納ラック２０の回転体２２に設けられるピニオンギア２２２と噛み合う要素である。そのため、ラックギア３２は、ピニオンギア２２２に対向する位置に設けられる。特に限定されるものではないが、本実施形態におけるラックギア３２は、図８に示されるように、収納ラック高さ位置調節部３０の前方側外壁３３の高さ方向に沿って形成される。 Further, the rack gear 32 of the storage rack height position adjusting unit 30 in the present embodiment is an element that meshes with the pinion gear 222 provided on the rotating body 22 of the storage rack 20. Therefore, the rack gear 32 is provided at a position facing the pinion gear 222. Although not particularly limited, the rack gear 32 in the present embodiment is formed along the height direction of the front outer wall 33 of the storage rack height position adjusting portion 30 as shown in FIG.

図示されるように（例えば図１）、本実施形態における一対の収納ラック高さ位置調節部３０ａ，３０ｂは、断熱扉１０の裏面側に略平行に設けられる。そのため、高さ位置の調節時に作用する第１凸部２１１、第２凸部２１２を含むリブ２１ａ，２１ｂを備えた収納ラック２０であって、リブ２１ａ，２１ｂ間の距離が略一定であれば、形状の異なる収納ラック２０であっても、収納ラック高さ位置調節部３０に適合させることができる。また、必要に応じて、収納ラック２０の数を増やす場合でも、収納ラック２０を収納ラック高さ位置調節部３０に装着させる作業を容易に行うことができる。 As shown (for example, FIG. 1), the pair of storage rack height position adjusting portions 30a and 30b in the present embodiment are provided substantially parallel to the back surface side of the heat insulating door 10. Therefore, if the storage rack 20 is provided with ribs 21a and 21b including the first convex portion 211 and the second convex portion 212 that act when adjusting the height position, and the distance between the ribs 21a and 21b is substantially constant. Even storage racks 20 having different shapes can be adapted to the storage rack height position adjusting unit 30. Further, even when the number of storage racks 20 is increased as needed, the work of mounting the storage racks 20 on the storage rack height position adjusting unit 30 can be easily performed.

次に、図９を参照して、収納ラック高さ位置調節部３０を断熱扉１０に取り付けるための取付部４０の構造を説明する。ここで、図９（ａ）は、断熱扉１０の内側から収納ラック高さ位置調節部３０を見た部分図である。また、図９（ｂ）は、図９（ａ）に示される断熱扉１０をＡ－Ａ’線で切断した断面を含む斜視図（取付部４０の構造を示す斜視図）である。なお、本実施形態において、突出壁１２１ａと１２１ｂは同一部材であるため、突出壁１２１ａと１２１ｂの双方を示すものとして、「突出壁１２１」と称する。 Next, with reference to FIG. 9, the structure of the mounting portion 40 for mounting the storage rack height position adjusting portion 30 to the heat insulating door 10 will be described. Here, FIG. 9A is a partial view of the storage rack height position adjusting portion 30 seen from the inside of the heat insulating door 10. Further, FIG. 9B is a perspective view (a perspective view showing the structure of the mounting portion 40) including a cross section of the heat insulating door 10 shown in FIG. 9A cut along the AA' line. In this embodiment, since the protruding walls 121a and 121b are the same member, they are referred to as "protruding walls 121" to indicate both the protruding walls 121a and 121b.

図９（ｂ）に示されるように、取付部４０は、突出壁１２１と対向する収納ラック高さ位置調節部３０の端面３４から突出する雄部４１と、雄部４１を着脱可能に取り付ける雌部４２とを備える。本実施形態における雄部４１は、皿ビスである。ここで、皿ビスは、収納ラック高さ位置調節部３０のレール溝３１から端面３４に掛けて貫通する貫通孔３５に挿入される。ただし、雄部４１の態様はこれに限られない。雄部４１の他の例として、貫通孔３５を通過せず、端面３４を起点に突出するリブ状の要素等が挙げられる。 As shown in FIG. 9B, the mounting portion 40 has a male portion 41 protruding from the end surface 34 of the storage rack height position adjusting portion 30 facing the protruding wall 121 and a female for detachably mounting the male portion 41. A unit 42 is provided. The male portion 41 in this embodiment is a countersunk screw. Here, the countersunk screw is inserted into the through hole 35 penetrating from the rail groove 31 of the storage rack height position adjusting portion 30 to the end surface 34. However, the aspect of the male part 41 is not limited to this. Another example of the male portion 41 is a rib-shaped element that does not pass through the through hole 35 and protrudes from the end surface 34 as a starting point.

また、雌部４２は、突出壁１２１の内部１２２側に装着される。本実施形態における雌部４２は、雄部４１が差し込まれる差込孔４２１を含む留具である。雄部４１と雌部４２とは、突出壁１２１を挟んで向き合うよう配置される。これにより、雌部４２は、雄部４１を着脱可能に取り付ける。ただし、雌部４２の態様もこれに限られない。なお、特に限定されるものではないが、突出壁１２１の内部１２２に雌部４２を装着した後、内部１２２に断熱材を充填することが好ましい。 Further, the female portion 42 is mounted on the inner 122 side of the protruding wall 121. The female portion 42 in the present embodiment is a fastener including an insertion hole 421 into which the male portion 41 is inserted. The male portion 41 and the female portion 42 are arranged so as to face each other with the protruding wall 121 interposed therebetween. As a result, the female portion 42 attaches the male portion 41 detachably. However, the aspect of the female portion 42 is not limited to this. Although not particularly limited, it is preferable to attach the female portion 42 to the inner 122 of the protruding wall 121 and then fill the inner 122 with a heat insulating material.

このように、収納ラック高さ位置調節部３０側に設けられる雄部４１が、突出壁１２１側に設けられる雌部４２に着脱可能に取り付けられる。そのため、収納ラック高さ位置調節部３０を断熱扉１０に後付けできる。これにより、既に提供されている冷蔵庫１の断熱扉１０の構造を変更することなく、収納ラック高さ位置調節部３０を取り付けることができる。すなわち、専用の断熱扉を設けなくても、汎用の断熱扉に収納ラック高さ位置調節部３０を取り付けることができる。その結果、製品のコスト高騰を招かない。 In this way, the male portion 41 provided on the storage rack height position adjusting portion 30 side is detachably attached to the female portion 42 provided on the protruding wall 121 side. Therefore, the storage rack height position adjusting portion 30 can be retrofitted to the heat insulating door 10. As a result, the storage rack height position adjusting portion 30 can be attached without changing the structure of the heat insulating door 10 of the refrigerator 1 already provided. That is, the storage rack height position adjusting unit 30 can be attached to the general-purpose heat insulating door without providing a dedicated heat insulating door. As a result, the cost of the product does not rise.

次に、図１０を参照して、断熱扉１０の突出壁１２１に設けられ、収納ラック高さ位置調節部３０を支持する支持部５０の構造を説明する。ここで、図１０（ａ）は、断熱扉１０を裏面側から見た部分斜視図である。また、図１０（ｂ）は、図１０（ａ）に示される断熱扉１０をＢ－Ｂ’線で切断した断面を含む斜視図（支持部５０の構造を示す斜視図）である。更に、図１０（ｃ）は、収納ラック高さ位置調節部３０が支持部５０に支持された状態の斜視図である。 Next, with reference to FIG. 10, the structure of the support portion 50 provided on the protruding wall 121 of the heat insulating door 10 and supporting the storage rack height position adjusting portion 30 will be described. Here, FIG. 10A is a partial perspective view of the heat insulating door 10 as viewed from the back surface side. Further, FIG. 10B is a perspective view (a perspective view showing the structure of the support portion 50) including a cross section of the heat insulating door 10 shown in FIG. 10A cut along the BB'line. Further, FIG. 10C is a perspective view showing a state in which the storage rack height position adjusting portion 30 is supported by the supporting portion 50.

図１０（ｂ）に示されるように、支持部５０は、断熱扉１０の突出壁１２１の内部１２２側に窪む凹部５１を備える。また、凹部５１の先端側に、支持部５０の幅方向外側に張り出し、基端５２に対して幅が拡張される拡幅部５３が形成される。ただし、拡幅部５３の位置は、凹部５１の先端に限られない。 As shown in FIG. 10B, the support portion 50 includes a recess 51 recessed on the inner 122 side of the protruding wall 121 of the heat insulating door 10. Further, on the tip end side of the recess 51, a widening portion 53 is formed which projects outward in the width direction of the support portion 50 and whose width is expanded with respect to the base end 52. However, the position of the widening portion 53 is not limited to the tip of the recess 51.

これに対して、図１０（ｃ）に示されるように、収納ラック高さ位置調節部３０は、突出壁１２１に対向する端面３４から突出し、凹部５１に収容される被収容凸部３６を備える。また、被収容凸部３６の先端側に、支持部５０の幅方向外側に張り出し、拡幅部５３に係合する係合部３７が形成される。ただし、係合部３７の位置は、被収容凸部３６の先端に限られない。 On the other hand, as shown in FIG. 10 (c), the storage rack height position adjusting portion 30 includes a stored convex portion 36 that protrudes from the end surface 34 facing the protruding wall 121 and is accommodated in the concave portion 51. .. Further, an engaging portion 37 is formed on the tip end side of the accommodated convex portion 36 so as to project outward in the width direction of the support portion 50 and engage with the widening portion 53. However, the position of the engaging portion 37 is not limited to the tip of the accommodated convex portion 36.

係合部３７が拡幅部５３に係合することで、収納ラック高さ位置調節部３０は、突出壁１２１により強固に固定される。これにより、収納ラック高さ位置調節部３０が落下するなどの事態を確実に防ぐことができる。更に、凹部５１における基端５２の幅を、収納ラック２０のリブ２１の幅に対応させれば、収納ラック高さ位置調節部３０が脱離した凹部５１に収納ラック２０のリブ２１を嵌め込むことができる。すなわち、収納ラック高さ位置調節部３０を固定する凹部５１によって、収納ラック２０を固定することができる。 By engaging the engaging portion 37 with the widening portion 53, the storage rack height position adjusting portion 30 is firmly fixed by the protruding wall 121. As a result, it is possible to reliably prevent a situation in which the height position adjusting portion 30 of the storage rack falls. Further, if the width of the base end 52 in the recess 51 corresponds to the width of the rib 21 of the storage rack 20, the rib 21 of the storage rack 20 is fitted into the recess 51 from which the height position adjusting portion 30 of the storage rack is detached. be able to. That is, the storage rack 20 can be fixed by the recess 51 that fixes the storage rack height position adjusting portion 30.

次に、図１１を参照して、収納ラック高さ位置調節部３０のレール溝３１に着脱可能に設けられる収納ラック支持部６０を説明する。ここで、図１１は、収納ラック支持部６０を含む拡大斜視図である。 Next, with reference to FIG. 11, a storage rack support portion 60 that is detachably provided in the rail groove 31 of the storage rack height position adjusting portion 30 will be described. Here, FIG. 11 is an enlarged perspective view including the storage rack support portion 60.

図１１に示されるように、収納ラック支持部６０は、収納ラック高さ位置調節部３０のレール溝３１内に着脱可能に嵌め込まれる差込片６１と、収納ラック２０を底壁側から支持する基部６２を備える。本実施形態における基部６２は、レール溝３１から断熱扉１０の幅方向内側に延在し、収納ラック２０の底壁２０Ｂと接触するプレート状の部材である。ただし、収納ラック支持部６０の態様は、これに限られない。 As shown in FIG. 11, the storage rack support portion 60 supports the insertion piece 61 detachably fitted in the rail groove 31 of the storage rack height position adjusting portion 30 and the storage rack 20 from the bottom wall side. It comprises a base 62. The base portion 62 in the present embodiment is a plate-shaped member extending inward in the width direction of the heat insulating door 10 from the rail groove 31 and in contact with the bottom wall 20B of the storage rack 20. However, the mode of the storage rack support portion 60 is not limited to this.

本実施形態によれば、このような構造の収納ラック支持部６０が収納ラック２０を支持するため、所定の高さ位置で収納ラック２０をより確実に支持することができる。また、差込片６１をレール溝３１に差し込む操作のみによって、収納ラック支持部６０を装着できる。そのため、収納ラック支持部６０をレール溝３１に簡便に取り付けることができる。 According to the present embodiment, since the storage rack support portion 60 having such a structure supports the storage rack 20, the storage rack 20 can be supported more reliably at a predetermined height position. Further, the storage rack support portion 60 can be mounted only by inserting the insertion piece 61 into the rail groove 31. Therefore, the storage rack support portion 60 can be easily attached to the rail groove 31.

［動作］
次に、図１２を参照して、収納ラック２０の高さ位置の固定とその解除動作を説明する。ここで、図１２（ａ）は、前記図８と同図であって、所定の高さ位置に固定された収納ラック２０を示す。また、図１２（ｂ）は、所定の高さ位置における固定が解除された収納ラック２０を示す。 [motion]
Next, with reference to FIG. 12, the fixing of the height position of the storage rack 20 and the release operation thereof will be described. Here, FIG. 12A is the same as FIG. 8 and shows the storage rack 20 fixed at a predetermined height position. Further, FIG. 12B shows a storage rack 20 that has been released from being fixed at a predetermined height position.

まず、収納ラック２０が所定の高さ位置まで移動すると、図１２（ａ）の左図に示されるように、リブ２１の第１凸部２１１とレール溝の第１凹部３１１とが係合すると共に、リブ２１の第２凸部２１２とレール溝３１の第２凹部３１２とが係合する。これにより、収納ラック２０は、収納ラック高さ位置調節部３０のレール溝３１に支持され、所定の高さ位置で固定される。 First, when the storage rack 20 moves to a predetermined height position, the first convex portion 211 of the rib 21 and the first concave portion 311 of the rail groove engage with each other as shown in the left figure of FIG. 12 (a). At the same time, the second convex portion 212 of the rib 21 and the second concave portion 312 of the rail groove 31 engage with each other. As a result, the storage rack 20 is supported by the rail groove 31 of the storage rack height position adjusting portion 30, and is fixed at a predetermined height position.

このとき、図１２（ａ）の右下図に示されるように、リブ２１の背壁２１Ｂにおいて、第１凸部２１１に対向する領域２１Ｂ１と、レール溝３１の第２側壁３１Ｓ２との間に間隙Ｓ１が形成されている。また、図１２（ａ）の右上図に示されるように、リブ２１の前壁２１Ｆにおいて、第２凸部２１２に対向する領域２１Ｆ１と、レール溝３１の第１側壁３１Ｓ１との間に間隙Ｓ２が形成されている。 At this time, as shown in the lower right figure of FIG. 12A, in the back wall 21B of the rib 21, there is a gap between the region 21B1 facing the first convex portion 211 and the second side wall 31S2 of the rail groove 31. S1 is formed. Further, as shown in the upper right view of FIG. 12A, in the front wall 21F of the rib 21, there is a gap S2 between the region 21F1 facing the second convex portion 212 and the first side wall 31S1 of the rail groove 31. Is formed.

この状態で、図１２（ｂ）の左図に示されるように収納ラック２０を傾ける（例えば、背方側を前方側より上昇させる）と、リブ２１とレール溝３１との間に間隙Ｓ１及びＳ２が形成されているため、図１２（ｂ）の右上図に示されるように、リブ２１の上方側が前方（図の右側）に向けて動くと共に、図１２（ｂ）の右下図に示されるように、リブ２１の下方側が背方（図の左側）に向けて動く。これにより、第１凸部２１１と第１凹部３１１との係合が解除されると同時に第２凸部２１２と第２凹部３１２との係合が解除される。その結果、収納ラック２０の固定が解除される。 In this state, when the storage rack 20 is tilted (for example, the back side is raised from the front side) as shown in the left figure of FIG. 12B, the gap S1 and the gap S1 between the rib 21 and the rail groove 31 are formed. Since S2 is formed, the upper side of the rib 21 moves forward (on the right side of the figure) as shown in the upper right figure of FIG. 12 (b), and is shown in the lower right figure of FIG. 12 (b). As shown above, the lower side of the rib 21 moves toward the back (left side in the figure). As a result, the engagement between the first convex portion 211 and the first concave portion 311 is released, and at the same time, the engagement between the second convex portion 212 and the second concave portion 312 is released. As a result, the storage rack 20 is released from being fixed.

固定が解除された収納ラック２０は、再び、上下移動可能な状態に戻る。続いて、収納ラック２０を上下移動させ、第１凸部２１１がレール溝３１の別の第１凹部３１１に係合し、第２凸部２１１がレール溝３１の別の第２凹部３１２に係合することで、収納ラック２０を異なる高さ位置に固定することができる。 The storage rack 20 that has been released from being fixed returns to a state in which it can move up and down again. Subsequently, the storage rack 20 is moved up and down, the first convex portion 211 engages with another first concave portion 311 of the rail groove 31, and the second convex portion 211 engages with another second concave portion 312 of the rail groove 31. By fitting, the storage rack 20 can be fixed at different height positions.

本実施形態によれば、リブ２１とレール溝３１との非常にシンプルな構造によって、収納ラック２０の高さ位置を調節できるため、製品の過度なコストアップを避けることができる。また、収納ラック２０を傾けるだけの作業で、収納ラック２０の固定を解除できるため、収納ラック２０の高さ調節を簡便に行うことができる。 According to the present embodiment, the height position of the storage rack 20 can be adjusted by the very simple structure of the rib 21 and the rail groove 31, so that it is possible to avoid an excessive cost increase of the product. Further, since the storage rack 20 can be released from being fixed only by tilting the storage rack 20, the height of the storage rack 20 can be easily adjusted.

ただし、収納ラック２０の固定を解除する態様は、図１２に示される態様に限られない。例えば、第１凸部２１１がリブ２１の上方側に設けられ、第２凸部２１２がリブ２１の下方側に設けられれば、収納ラック２０の背方側を前方側より降下させて（図１２（ｂ）とは逆方向に収納ラック２０を傾斜させて）、収納ラック２０の固定を解除することができる。また、それ以外の態様であってもよい。 However, the mode of releasing the fixing of the storage rack 20 is not limited to the mode shown in FIG. For example, if the first convex portion 211 is provided on the upper side of the rib 21 and the second convex portion 212 is provided on the lower side of the rib 21, the back side of the storage rack 20 is lowered from the front side (FIG. 12). The storage rack 20 can be released from the fixing by tilting the storage rack 20 in the direction opposite to (b). In addition, other aspects may be used.

次に、図１３を参照して、収納ラック２０に備わる回転体２２とロックレバー２３との作用を説明する。ここで、図１３（ａ）は、収納ラック２０上昇時の回転体２２とロックレバー２３との作用を説明する図である。また、図１３（ｂ）は、収納ラック２０降下時の回転体２２とロックレバー２３との作用を説明する図である。 Next, with reference to FIG. 13, the operation of the rotating body 22 provided in the storage rack 20 and the lock lever 23 will be described. Here, FIG. 13A is a diagram illustrating the action of the rotating body 22 and the lock lever 23 when the storage rack 20 is raised. Further, FIG. 13B is a diagram illustrating the action of the rotating body 22 and the lock lever 23 when the storage rack 20 is lowered.

まず、収納ラック２０が上昇すると、収納ラック高さ調節部３０のラックギアに噛み合うピニオンギア２２２が回転する。それに連動して、基板２２１を介してピニオンギア２２２と連結する爪部２２４が、図１３（ａ）に示される矢印方向に回転する。このとき、爪部２２４の傾斜面２２４Ｓと、ロックレバー２３の衝突凸部２３３を構成する一面２３３Ｓとが衝突する。 First, when the storage rack 20 rises, the pinion gear 222 that meshes with the rack gear of the storage rack height adjusting unit 30 rotates. In conjunction with this, the claw portion 224 connected to the pinion gear 222 via the substrate 221 rotates in the direction of the arrow shown in FIG. 13 (a). At this time, the inclined surface 224S of the claw portion 224 and the one surface 233S constituting the collision convex portion 233 of the lock lever 23 collide with each other.

前記の通り、一面２３３Ｓは、傾斜面２２４Ｓに対応して傾斜する。また、ロックレバー２３の衝突凸部２３３を含む他端側２３２は、一端側２３１を軸に回動可能な状態とされている。そのため、傾斜面２２４Ｓが一面２３３Ｓに衝突した後、傾斜面２２４Ｓが一面２３３Ｓ上を摺動すると共に、傾斜面２２４Ｓの衝突圧力によって、ロックレバー２３の他端側２３２は、上方に向けて押動される。 As described above, the one surface 233S is inclined corresponding to the inclined surface 224S. Further, the other end side 232 including the collision convex portion 233 of the lock lever 23 is in a state of being rotatable about the one end side 231. Therefore, after the inclined surface 224S collides with the one surface 233S, the inclined surface 224S slides on the one surface 233S, and the collision pressure of the inclined surface 224S pushes the other end side 232 of the lock lever 23 upward. Will be done.

すなわち、図１３（ａ）に示される爪部２２４の回転動作は、ロックレバー２３によっては停止されない。このように、爪部２２４は、そのまま回転を継続できる結果、収納ラック２０の動作も阻害されない。なお、収納ラック高さ調節部３０のラックギア３２と噛み合う回転体２２のピニオンギア２２２の回転によって、収納ラック２０の上昇操作がアシストされる。 That is, the rotational operation of the claw portion 224 shown in FIG. 13A is not stopped by the lock lever 23. As described above, the claw portion 224 can continue to rotate as it is, and as a result, the operation of the storage rack 20 is not hindered. The ascending operation of the storage rack 20 is assisted by the rotation of the pinion gear 222 of the rotating body 22 that meshes with the rack gear 32 of the storage rack height adjusting unit 30.

これに対して、収納ラック２０が降下すると、ピニオンラック２２２及び爪部２２４は、図１３（ｂ）に示される矢印方向に回転する。このとき、爪部２２４の垂直面２２４Ｖと、前記一面２３３Ｓと共にロックレバー２３の衝突凸部２３３を構成する他面２３３Ｖとが衝突する。 On the other hand, when the storage rack 20 is lowered, the pinion rack 222 and the claw portion 224 rotate in the direction of the arrow shown in FIG. 13 (b). At this time, the vertical surface 224V of the claw portion 224 and the other surface 233V constituting the collision convex portion 233 of the lock lever 23 collide with the one surface 233S.

前記の通り、爪部２２４の垂直面２２４Ｖは、環状部２２３の外周面から垂直に立ち上がる。また、ロックレバー２３の他面２３３Ｖは、ロックレバー２３の底部から下方に向けて垂設される。そのため、他面２３３Ｖに衝突する垂直面２２４Ｖの移動方向は、他面２３３Ｖに略直交する。このことから、垂直面２２４Ｖと他面２３３Ｖとが物理的に干渉する。その結果、垂直面２２４Ｖのそれ以上の回転は、他面２３３Ｖによって阻害される。それに応じて、ピニオンギア２２２の回転も止まるため、収納ラック２０の更なる降下が停止される。 As described above, the vertical surface 224V of the claw portion 224 rises vertically from the outer peripheral surface of the annular portion 223. Further, the other surface 233V of the lock lever 23 is vertically installed downward from the bottom of the lock lever 23. Therefore, the moving direction of the vertical surface 224V that collides with the other surface 233V is substantially orthogonal to the other surface 233V. From this, the vertical surface 224V and the other surface 233V physically interfere with each other. As a result, further rotation of the vertical surface 224V is hindered by the other surface 233V. Accordingly, the rotation of the pinion gear 222 is also stopped, so that further descent of the storage rack 20 is stopped.

このように、ロックレバー２３の作用によって、収納ラック２０の降下が停止される。そのため、収納ラック２０のリブ２１と収納ラック高さ調節部３０のレール溝３１との係合が仮に不十分な場合であっても、爪部２２４とロックレバー２３との作用によって、収納ラック２０の落下やレール溝３１からの脱落などの事態を防ぐことができる。 In this way, the action of the lock lever 23 stops the descent of the storage rack 20. Therefore, even if the rib 21 of the storage rack 20 and the rail groove 31 of the storage rack height adjusting portion 30 are not sufficiently engaged, the storage rack 20 is affected by the action of the claw portion 224 and the lock lever 23. It is possible to prevent a situation such as a drop of the rail or a fall from the rail groove 31.

なお、収納ラック２０の高さ位置を意図的に下げたい場合、ロックレバー２３の他端側２３２を持ち上げる操作を行う。これにより、爪部２２４と衝突凸部２３３との衝突が回避され、図１３（ｂ）に示される爪部２２４の回転が阻害されない。その結果、ピニオンギア２２２がラックギア３２に噛み合いながら回転でき、収納ラック２０の降下が許容される。 If it is desired to intentionally lower the height position of the storage rack 20, the operation of lifting the other end side 232 of the lock lever 23 is performed. As a result, the collision between the claw portion 224 and the collision convex portion 233 is avoided, and the rotation of the claw portion 224 shown in FIG. 13 (b) is not hindered. As a result, the pinion gear 222 can rotate while meshing with the rack gear 32, and the storage rack 20 is allowed to descend.
