Further, a belt side support / support means 29 is formed at the base of the belt side engagement means so as to face the belt member 21. In this case, the belt-side support / supported means 29 is a support means formed of a slit-shaped recess as shown in FIG. 2, and is used as described later.

The second fixing plate 30 is also referred to as an “engagement fixing plate”, and includes a fixing plate main body 31 provided with mounting means 31 a on the back surface, and a cover 32 fixed so as to cover the fixing plate main body 31. In the internal space formed by the solid plate main body 31 and the cover 32, the disengagement member 34 is accommodated in a deformable manner.
The disengagement member 34 is a component for realizing the engagement / release function of the belt side engagement means 27 with respect to the engagement receiving portion. The disengagement member 34 has an outward claw portion at the tip and is directed toward the belt member 21 side. Fixed engaging means 35, 35 formed of a pair of upper and lower leg pieces that are extended and flexible, and a tongue piece shape extending upward and downward so as to be in a direction away from the middle of each leg piece 35, 35. (Release) operation units 36 and 36 are provided. The base portions of the leg pieces 35 and 35 are integrally formed in a V shape to exert a spring action, and the operation portions 36 and 36 are biased in a direction away from each other.

The disengagement member 34 is accommodated in the internal space between the cover 32 and the fixed plate body 31 as shown in FIG. In this state, the fixed engagement means 35 are connected to the opening of the cover 32 (not shown) on the belt member 21 side, and this is received by the engagement receiving portion of the belt side engagement means 27 inserted from the opening. Is engaged. That is, by pressing the belt side engaging means 27 against the disengaging member 34, the leg pieces 35 and 35 described with reference to FIG. 3 which are the fixed engaging means 35 and 35 are deformed inwardly, and FIG. The belt side engaging means 27 described above is received between the claws 28 and 28 inward. And it engages by making the step part of a nail | claw part contact | abut mutually, and it sets as FIG.
When the operation portions 36 and 36 exposed from the upper and lower openings 38a and 38a of the cover 32 are picked from the upper and lower sides and bent inward, the claw portions of the leg pieces 35 and 35 and the belt-side engagement means 27 are connected to each other. The engagement with the direction claw portions 28, 28 is released.
In addition, the direction of each nail | claw part of the belt side engaging means 27 and the fixed side engaging means 35 may be formed reversely, and each engaging means 27 and 35 employs what is called a buckle. However, various other engaging means such as hooks, snap buttons, and hook-and-loop fasteners may be employed.

The fixed plate body 12, the cover member 14, the fixed side support / supported means 13, the belt side engaging means 27, the fixed plate main body 31, the cover member 32, and the disengagement member 34 are made of hard synthetic resin, for example, It is formed of a synthetic resin molded product made of ABS resin, AS resin, polypropylene, polystyrene, polymethyl methacrylate, or the like. Note that the belt member 21 formed of a soft member may be integrally formed by integral molding such as two-color molding with respect to the belt fixing plate 11 and the belt side engaging means 27 formed of a hard material.
Preferably, elastic portions 13a and 33 are formed on at least one of the surface of the fixed-side support / supported means 13 and the surface of the cover 32, respectively. This is because the elastomer or the like is integrally formed on the surface of the cover 32 or the like by two-color molding or the like, and these surfaces are covered by bonding, so that it is injured when an infant or the like collides with it or is uncomfortable such as pain. This is for preventing irritation and preventing breakage.

The present embodiment is configured as described above. For example, when the opening prevention device 10 of the present embodiment is used in a refrigerator, the fixing plate main body 12 is disposed on the side surface of the refrigerator, for example, while corresponding to the length of the belt member 21. Fixing is performed by the mounting means 12a, and the fixing plate body 31 is fixed to the front surface of the refrigerator door by the mounting means 31a. Thereby, since the belt member 21 fixed to the first fixing plate 11 is engaged with the second fixing plate 30, the door cannot be opened and the refrigerator can be prevented from opening.
At this time, since the engagement between the belt-side engaging means 27 fixed to the belt member 21 and the second fixing plate 30 is not released unless the operation portions 36 are picked up and deformed from above and below, the infant is engaged. The refrigerator cannot be opened.

  Next, when a guardian or the like frequently opens and closes, when the engagement between the belt-side engagement means 27 and the fixed-side engagement means 35 is released by the (release) operation portions 36, 36, The belt-side engaging means 27 at the other end is in a state of being detached from the second fixing plate 30. In this state, the flexible belt member 21 can be bent or curved and the fixed-side support / supported means 13 can be inserted into the belt-side support / supported means 29 and temporarily fixed.

This state is shown in FIG.
As shown in the drawing, the belt shown in FIG. 3 is formed by folding a long structure excluding the second fixing plate 30 (see FIG. 3) from the opening preventer 10 so as to be reversed at the belt member 21 portion. The tip of an oval thin plate as the fixed side supported portion 13 is inserted into the concave portion as the side support portion 29 and temporarily fixed. At this time, the claw portions 28 and 28 are covered with a blindfold 28a.
As a result, the belt-side engaging means removed from the door or the like hangs down on the path of the door to be closed at the front end of the belt member that has become a free end, as in the prior art, thereby obstructing the opening and closing of the door. This makes it easier to open and close the door, improving usability.
The belt-side support portion 29 may be configured as a “supported portion” instead of a support portion, such as an inserted thin plate, protrusion, or convex portion. In this case, the fixed-side supported portion 13 is not supported. Of course, instead of the support portion, a “support portion” composed of a recess or the like for supporting the inserted object may be used.

Moreover, the following use is possible, without temporarily fixing as mentioned above.
That is, as explained in FIG. 3, the belt side fixing means 22 is rotatably fixed around the shaft portion 15 which is the fixing plate side fixing means. For this reason, when the engagement between the belt side engaging means 27 and the fixed side engaging means 35 is released, the belt member 21 hangs down with the belt side engaging means 27 attached to the tip, Does not obstruct the path of the door to be opened and closed. Thereby, when the belt side engaging means 27 which is a part of the door to be opened or the means for fixing to the drawer is removed, the opening / closing operation can be prevented.
In other words, when it is assumed that the door is opened and closed very frequently, for example during cooking, the user performs support by the support parts / supported parts 13 and 29 and suddenly wants to maintain the release state. Can be selected so that the belt member 21 can be rotated and repeatedly opened and closed easily.

Thereby, the distance provided between the belt fixing plate 11-1 and the engagement fixing plate 30-1 can be adjusted to an uninterrupted floor, and can be sandwiched and fixed between the fixing plate main body 12 and the cover member 14.

  Further, the configuration of the engagement fixing plate 30-1 is different. That is, as shown in FIG. 6, in the disengagement member 34-1, a long slit 39 is formed along the length direction of the belt member 21 between the pair of fixed side engagement means 35, 35. The boss 31b formed on the inner surface of the fixed plate main body 31-1 is inserted. That is, the engagement releasing member 34-1 is accommodated between the cover 32-1 and the fixed plate main body 31-1, and can move relatively in the arrow A direction.

Further, a long hole 38 is formed on the surface side of the cover 32, and an engagement operation projection 37 formed in an end portion on the opposite side of the fixed side engagement means 35 of the engagement release member 34-1. Is inserted and protrudes to the outside.
As a result, the disengagement member 34 is brought into contact with the belt side engagement means 27, and the user engages the engagement operation projection 37 exposed from the long hole 38 as shown in FIG. When moved in the A1 direction, which is a direction close to the means 27, the leg pieces 35, 35 of FIG. 6 as the fixed engagement means 35, 35 are deformed inward, and the belt side engagement means 27 faces inward. Are received between the nail portions 28, 28. And it engages by making the step part of a nail | claw part contact | abut mutually.
When releasing the engagement, if the operation portion 36 is deformed and moved in the A2 direction, which is a direction away from the belt-side engagement means 27, the fixed engagement means 35 becomes a claw of the belt-side engagement means 27. Received and engaged between the portions 28,28.
As described above, when engaging, not only the belt side engaging means 27 but also the engaging operation projection 37 should be operated. The disengaged state can also be maintained on the plate 30 side.

Further, as shown in FIG. 6, a boss 13-1 that is a convex portion protrudes from the cover member 14 as a fixed-side supported means.
On the other hand, the belt side fixing means 27 is formed with a hole 29-1, which is a recess, as a belt side support means. By inserting the boss 13-1 into the hole 19-1, FIG. It can be temporarily fixed to the point explained.
The second embodiment is configured as described above, and can exhibit the same functions and effects as those of the first embodiment.

  The present invention is not limited to the description of the above-described embodiment. For example, the belt fixing plate 11 side may have the same structure as the engagement fixing plate 12 side, and the engaging means 27 and 35 and the operation unit 36 may be provided on both sides. In this case, the supporting means 13 and 29 are provided. By providing one or both, temporary fixing by the support means functions effectively.
