Description of the Related Art Generally, in a door of a cooling storage, etc., as seen in Japanese Utility Model Publication No. 54-45250, a door stopper is provided near the pivot of the door on the side opposite to the handle, and this hinges when the door is opened. It is designed to be in contact with a member and open up to a certain angle.

FIG. 8 shows a door opening / closing device having the same meaning as in the above publication. Reference numeral 1 is a main body of the cooling storage 2, and has storage chambers 3 which are divided into upper and lower parts. Reference numeral 4 denotes a double-door type door that opens and closes the storage chamber 3 and is rotatably supported by a hinge shaft 6 (upper hinge shaft is not shown) projecting from the upper and lower sides of one side of hinge members 5 and 5. There is. The hinge member 5 is attached and fixed to the lateral frame portion 7 that partitions the storage chambers 3, 3 with bolts 8. At the lower edge 4b of the door 4, a door stopper 10 having an inverted L-shaped cross section is attached with a screw 11 at a position near the pivot portion. Figure 9,
Reference numeral 10 shows an appearance and a plan view of a door stopper 10 having mounting holes 12 and 12 for screws 11.

Here, when the door 4 is closed, it is located at the taper edge portion 5b of the hinge member 5, and when the door 4 is rotated in the direction of opening with the handle 12 as shown in the drawing, the hinge is opened. The side edge of the hanging piece 10b of the door stopper 10 comes into contact with the mountain-shaped locking portion 5a formed on the base end portion of the member 5 to prevent the door 4 from rotating further, and to open and close the door 4. The angle is regulated. As can be seen from the figure, the door stopper 10 has a mechanism in which the door opening / closing angle becomes narrower in the direction of arrow A and becomes wider in the direction of arrow B.

[0005]

However, conventionally, the door stopper 10 is fixed to the lower edge 4b of the door 4 by a two-point stop with screws or the like, and one door stopper 10 corresponds to one door opening / closing angle. .

However, in the case of a cold storage or the like, when it is necessary to change the opening / closing angle of the door due to the circumstances of use and installation of the product, the door stopper must be replaced with a special angle, and the door stopper must be replaced. Since there are few types of stoppers, they are custom-made and there is a problem that it takes time to respond.

Further, the door of the cooling storage, which has been used at a certain opening / closing angle, cannot be easily set by the user as needed, which is troublesome.

The present invention has been made in view of the above points,
(EN) Provided is a door opening / closing device configured such that the door opening / closing angle can be freely adjusted and changed with one door stopper.
