Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a locking device for a storage cabinet having a plurality of doors, such as a commercial refrigerator.

(Prior Art) Conventionally, a locking device for a storage warehouse having a plurality of doors has a locking device of approximately U which is rotatably provided with bent portions at both ends as a fulcrum.
It consists of a shaped key hanger, a mounting bracket with a part that accepts the bent part, a key plate that holds one corner of multiple doors at the same time, and a lock that fixes the key plate to the lock hanger. A conventional locking device of this type is shown in FIGS. 7 and 8,
A portion 1a of the mounting bracket 1 that receives the bent portion 2a of the lock hook 2 has a U-shape.

(Problem to be solved by the invention) Therefore, in the conventional structure, even if the locking tool 2 is knocked down when the lock is not locked, the edge of the opening 1b between the parts 1a where the locking tool 2 receives the bent part Therefore, as shown by the imaginary line in FIG. 7, the mounting bracket 1 is not parallel to the surface of the column to which it is fixed, but is tilted at an angle θ. As a result, it has the disadvantage that it looks bad and also becomes a nuisance when all the doors are opened to take in and take out products. Also, if you dare to allow a margin in the part 1a of the mounting bracket to receive the bent part 2a, backlash will occur and the bent part will not fit in that part 1a.
There was a problem that it could easily come off.

The purpose of this invention is to solve the above-mentioned problems of the conventional technology, and therefore, when the lock hanger is folded down, it is parallel to the surface of the pillar, so that it looks good and does not get in the way. It is an object of the present invention to provide a locking device for a storage room.

(Means for Solving the Problems) The locking device according to the present invention is characterized by, as shown in FIGS. The shape of the mounting bracket 10 is made into an Ω-shape, so that a gap approximately equal to the plate thickness t of the mounting bracket 10 is created between the surface of the column 3 to which the mounting bracket 10 is fixed and the bent portion 2a.

(Operation of the means for solving the problem) As described above, in the locking device according to the present invention, since the receiving part 11 of the bent part of the mounting bracket is Ω-shaped, the locking tool 2 can be rotated. At all angular positions, there is a gap approximately equal to the plate thickness t of the mounting bracket between the bent part 2a and the surface of the pillar 3, and when the locking fixture 2 is folded down, it is shown as an imaginary line in Fig. 1. As shown,
It becomes parallel to the plane of column 3.

(Example) Next, an example of the present invention will be described with reference to the drawings.
Figures 5 and 6 show a refrigerator as an example of a storage unit equipped with a locking device to which the present invention relates, and this storage unit is provided with a column 3 vertically in the center of the front opening; A plurality of doors 4 covering the opening are each held down at one corner by a key plate 5 and fixed with a lock 6.

FIG. 1 shows the entirety of an example of the locking device of the present invention, and FIGS. 2 to 4 show the members included therein. As is clear from FIG. 1, this locking device is also conventional. Similarly, bent portions 2a at both ends of a substantially U-shaped locking tool 2 as shown in FIG. 3 are rotatably held down by portions 11 of a mounting bracket 10. The mounting bracket 10 is fixed to the front surface of the column 3 with screws 7. As shown in FIG. 4, in the center of the key plate 5 there is a long hole 5a for receiving the tip of the locking tool 2. Note that the same key hanger 2, key plate 5, and lock 6 as conventional ones can be used.

The locking device according to the present invention has a feature in the mounting bracket 10 that holds the locking tool 2, and has a first feature.
As shown in the figure and FIG. 2, the shape of each portion 11 of the mounting bracket 10 that receives the bent portions 2a at both ends of the locking tool is Ω-shaped. Like this Ω
By receiving the bent portion 2a of the locking device in the shaped portion 11, the bent portion 2a is aligned with the surface of the column 3 as shown in FIG. , and a gap approximately equal to the plate thickness t of the mounting bracket 10 is created therebetween.

(Effect of the invention) As described above, according to the invention, since the part of the mounting bracket that receives the bent part of the locking tool is Ω-shaped, the bent part of the locking tool is In addition to being able to properly hold the lock, when the lock hanger is knocked down when the lock is not locked, the mounting bracket can be made parallel to the surface of the pillar to which it is fixed. As a result, it looks good, and there is little protrusion of the lock hook from the surface of the pillar, so it does not get in the way when putting in and taking out products.
