いることから製品の原価アツプとなる。 The conventional door opening prevention structure will be explained with reference to FIGS. 1 and 2. 1 is the refrigerator body, 2 is the freezer compartment door (or refrigerator compartment door), and a locking member 8, which will be explained later, is attached to the bottom surface of the refrigerator compartment door. There is. Reference numeral 3 denotes a refrigerator compartment door (or a freezer compartment door), and the freezer compartment door 2 and the refrigerator compartment door 3 are attached to the refrigerator main body 1 by an upper hinge 4, a middle hinge 5, and a lower hinge 6. In addition, the door 2 and door 3
rotates around the pins of the upper hinge 4, middle hinge 5, and lower hinge. Reference numeral 7 denotes a spring which is a locking piece made of an elastic body and has a convex portion 7a at its tip, and is attached at the same time as the middle hinge 5 by screws 9 that fix the middle hinge 5 to the refrigerator main body 1. Reference numeral 8 denotes a locking member attached to the lower surface of the freezer compartment door 2, and a convex portion 8 is provided downwardly.
It has a. With the freezer compartment door 2 closed, the protrusion 8a of the locking member 8 and the protrusion 7a of the leaf spring 7 on the refrigerator main body 1 side are engaged. Reference numeral 10 denotes a magnetic gasket attached to the front surface of the outer periphery of the door 2 and door 3, which is attracted to the front surface of the outer periphery of the refrigerator body 1. Normally, when the refrigerator compartment door 3 is closed with a certain amount of force, the pressure in the refrigerator compartment increases, and this pressure reaches the freezer compartment through the cold air passage inside the partition, and tries to open the freezer compartment door 2. Therefore, it is forcibly locked.
The details will be explained below with reference to FIG. 2. When the freezer compartment door 2 is closed, the convex part 7a of the leaf spring 7 and the convex part 8a of the locking member 8 are engaged with each other without a gap. In order to open it, it is necessary to climb over the convex portion 7a of the leaf spring 7. Therefore, a force is required to overcome the problem, which prevents the door from opening. In the above structure, if the door attachment (packet dimension B) varies in the smaller direction, the gap between the convex part 8a of the locking member 8 on the lower surface of the freezer compartment door 2 and the convex part 7a of the leaf spring 7 on the main body side. A gap occurs between the two. As a result, the door 2 that has stopped between the gaps remains open. Therefore, in practice, the tip convex portion 7a of the leaf spring 7 is lifted upward, thereby eliminating the gap and adjusting the spring 7 so that it is locked with the locking member 8. Therefore, the cost of the product increases as more personnel are required to make adjustments.
従つて本考案はかかる欠点を改良したもので、
即ち扉２が前後方向にバラツいて取付けられた場
合でも常に係止部材８とイタバネ７が係止される
ようにしたものである。 Therefore, the present invention improves these drawbacks.
That is, even if the door 2 is installed unevenly in the front-back direction, the locking member 8 and the leaf spring 7 are always locked.

とは若干のギヤツプが設けられている。 An embodiment of the present invention will be explained below with reference to FIGS. 3 and 4. 11 is a locking piece made of an elastic body and a spring is divided into two from the center, and one piece is 11a, which has a convex tip. part 11a', and the other part is 1
1b has a convex portion 11b' at its tip. The convex portion 11a' protrudes several millimeters in front of 11b' (on the contrary, 11b' may protrude several millimeters in front of 11a'). Reference numeral 12 denotes a locking member whose tip has a downward convex portion 12a, which is connected to the convex portion 11 of the leaf spring 11.
a', 11b'. With the above structure, the normal freezer compartment door 2
For installation, as shown in Figure 4, please use the Itabane 1
The convex portion 12a of the locking member 12 comes into contact with the vicinity of the apex of the tip 11b' of the piece 11b of the locking member 12. Further, the convex portion 11a' of the other piece 11a is the locking portion 12a.
There is a slight gap between the two.

る。 In the above structure, a closing force is always applied to the protrusion 12a (freezer compartment door 2) of the locking member 12 by the piece 11b of the leaf spring 11. Further, since the other piece 11a is locked with the locking member 12 when the freezer compartment door 2 is slightly opened, a closing force is applied to the door 2. Therefore, the holding force of the freezer compartment door 2 (the closing force of the refrigerator compartment door to open the freezer compartment door when the refrigerator compartment door is closed) is the magnetizing force of the magnetic packing 10 + the leaf spring 11.
It becomes the power of Next, a case where the freezer compartment door 2 is installed unevenly will be explained with reference to FIGS. 5 and 6. First, when the freezer compartment door 2 is installed close to the main body 1 (the seal dimension B is small), the convex portion 1 of the piece 11b of the leaf spring 11 is
1b' and the convex portion 12a of the locking member 12 are locked without a gap. Therefore, as described above, the holding force of the freezer compartment door 2 is the magnetizing force of the magnetic packing 10 + the force of the leaf spring 11. Further, there is a gap of several millimeters between the protrusion 11a' of the other 11a and the protrusion 12a of the locking member 12. Next, when the freezer compartment door 2 is installed apart from the main body 1 (the packing size B is large), the convex portion 11a' of the piece 11a of the leaf spring 11 and the convex portion 12 of the locking member 12 as shown in FIG.
The freezer compartment door 2 is locked in place without a gap.
The holding force is the magnetizing force of the magnetic packing 10 + the force of the leaf spring 11. In addition, the convex portion 1 of the other 11b
1b' contacts the apex of the convex portion 12a of the locking member 12a.

原価低減になるものである。 As described above, the present invention divides the spring that forms the locking piece attached to the main body side into left and right halves, and shifts the positions of the left and right convex parts in the front and back direction, so that when the door is closed, Since the convex part of the locking member and the convex part of one of the leaf springs forming the locking piece on the main body side are always locked, even if the installation of the freezer compartment door 2 is uneven in the front and back, the main body 1 Since the leaf spring on the side and the locking member on the door 2 side are locked without a gap, the holding force of the freezer compartment door can be ensured. Therefore, it is no longer necessary to adjust the leaf spring 11 on the main body 1 side, which was conventionally done to ensure the holding force of the freezer compartment door 2, resulting in a reduction in the number of personnel and a reduction in the cost of the product.
尚、本実施例によれば本体側の係止片はバネ鋼
材、もしくはプラスチツク材に於いても上記と同
様な効果が得られる。 According to this embodiment, the same effect as described above can be obtained even if the locking piece on the main body side is made of spring steel or plastic.
