て解錠を達成するのに支障はない。 Since the unlocking device according to this invention is as described above, first, as shown in Fig. 4 a, b, and c,
When the handle 8d of the operating lever 8 is rotated clockwise and the arcuate portion 8a is engaged with the stepped portion 13a of the receiving bracket 13 and the convex portion 8b is engaged with the groove 13c, the arcuate portion 8
A reaction force F 1 ′ acts on the support shaft 10 as a reaction force of the force F 1 that a presses against the stepped portion 13a, and this reaction force F 1 ′ causes the door 3 and the latch 5 to move in the direction of the hinge 4 (arrow B
direction) by the amount of clearance created between the hinge 4 and door 3, further rotate the handle 8d clockwise, and make the operating lever 8 horizontal.
As shown in b and c, in addition to the pressing reaction force F 1 ', the convex part 8b moves downward along the groove 13c, and the convex part 8b
A reaction force F 2 ′ acts on the support shaft 10 and the like in the direction outside the refrigerator as a reaction force of the force F 2 that presses the groove 13c toward the inside of the refrigerator.
The pressing force of this reaction force F 2 ' applies a pressing force (in the direction of arrow C) to the shaft 6c of the roller rotating body 6b of the latch receiver 6.
Due to the pressing force, the shaft 6 of the latch receiver 6
Taking into account that the latch receiver 6 is attached to the synthetic resin storage door frame 2a, the part c moves in the direction of disengaging the latch lock 5 (in the direction of arrow D), and the latch locking part 5a moves in the direction of disengaging the latch lock 5. When the tip of the latch receiver 6 is moved outward from the axis of the shaft 6c, the roller rotating body 6b rotates and the door 3 opens in the opening direction (arrow C direction). In practice, when the door 3 is closed, the amount that the tip of the latch locking portion 5a enters inward from the axis of the shaft 6c, that is, the amount of engagement is generally about 7 mm at most. There is no problem in achieving unlocking by rotational operation.
以上に述べたように、この考案による解錠装置
によれば、扉３等の厚さに関係なく、一種類の該
装置で、いかなる厚みの扉３にも取付けが可能で
あるため、生産が容易で、かつ安価となり、また
生産管理がより容易となる。
As described above, according to the unlocking device according to this invention, regardless of the thickness of the door 3, etc., one type of the device can be attached to the door 3 of any thickness, which reduces production. It is easy and inexpensive, and production management is easier.
また、ラツチ錠５、ラツチ受け６及び押棒７と
機械的に全く関係がなく、ラツチ錠５の解錠がで
きるため、該装置の取付けが容易で取付け位置の
制限も小さい。 Furthermore, since there is no mechanical relationship with the latch 5, latch receiver 6, and push rod 7, and the latch 5 can be unlocked, the device can be easily installed and there are few restrictions on the installation position.
また、操作レバー８の把手８ｄを回転するのみ
で作動し、多少の氷結があつても容易かつ確実に
作動し、機構も簡単なため、故障、不作動がな
く、安全性が確保され、原状復帰も容易で、部品

る。 In addition, it operates simply by rotating the handle 8d of the operating lever 8, and it operates easily and reliably even in the presence of some ice.Since the mechanism is simple, there is no failure or malfunction, and safety is ensured. This has advantages such as easy restoration and no need to replace parts.
