DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show an embodiment in which the present invention is applied to a refrigerator. A refrigerator 10 of this embodiment has a box-shaped storage main body 11, an upper hinge 12 on a front surface of the storage main body 11, and a middle hinge. A pair of upper and lower doors 15, which are rotatably assembled via a lower hinge 13 and a lower hinge 14 to open and close a pair of upper and lower openings (a front opening of a refrigerated storage chamber, not shown) provided on the front surface of the storage main body 11; 16 and a refrigerating device 17 disposed on the upper portion of the storage main body 11, and each lock device 20 is attached to each of the doors 15 and 16.

Each lock device 20 includes a lock mounting plate 21 mounted on the storage body 11 and a lock mounting plate 21
, The doors 15 and 16 cannot be opened by the lock body 22. The lock mounting plate 21 is formed by integrally fixing a spacer 23 in advance, and has an L-shape along the front and side surfaces of the storage main body 11. Similarly, two rivets 24 are used to secure the mounting hole 11a of the storage main body 11 that has been drilled, and provided on the front left and right sides of the storage main body 11 with respect to the front of the storage main body 11. Using the hinge mounting hole 11b to which the hinges 12 and 13 cannot be attached, two screws 2
5 is fixed. When each lock device 20 is not assembled, each hinge mounting hole 11b is
Decorative screw 1 like the hinge mounting hole for the lower hinge shown in
8 to be hidden.

The lock body 22 is of a well-known type. The arm 22a is rotatable by a predetermined amount so that the doors 15 and 16 cannot be opened or can be opened, and a key cylinder 22b for restricting and allowing the rotation of the arm 22a. And is fixed to the spacer 23 using two screws 26.
A cap 27 is attached so that the head of No. 6 is hidden. The key cylinder 22b is locked / unlocked (rotation restriction / rotation permission) by turning the key 28 in and out, and is turned integrally with the arm 22a by inserting the key 28 and turning. It has become.

[0010] In the lock device 20 of the present embodiment configured as described above, the lock mounting plate 21 is connected to the storage main body 1.
6 is fixed to the lock main body 11 with screws 25 and rivets 24 on the front and side surfaces of the storage main body 11 as L-shaped shapes along the front and side surfaces of the storage main body 11, respectively. , The force in the direction of the arrow in FIG. 7) acts, the lock mounting plate 21 does not easily bend, and the lock body 22 performs its original locking function.

Further, in the lock device 20 of the present embodiment, as the mounting holes for fixing the lock mounting plate 21 to the front surface of the housing main body 11, the hinges 12 are provided on the right and left sides of the front surface of the housing main body 11. Since the hinge mounting hole 11b to which the door 13 is not attached is used, the hinge mounting hole 11b provided in advance in the storage main body 11 is effectively used so that a left-opening or right-opening door can be mounted. The mounting plate 21 can be attached. In particular, when a part (not shown) such as a front frame heater wire or a dry pipe for preventing dew condensation is disposed on a front part (in a front wall) of the storage body 11. Can quickly and accurately perform the mounting operation of the lock device 20 without worrying about the arrangement of the components.

In the above embodiment, the lock mounting plate 2
The hinge mounting holes 11b provided on the front left and right sides of the housing main body 11 and to which the hinges 12 and 13 cannot be attached are used as mounting holes for fixing the housing 1 to the front surface of the housing main body 11. When components such as a front frame heater wire or a dry pipe for preventing dew condensation are not provided at the front portion of the lock 11, the lock mounting plate 21 is fixed to the front surface of the storage body 11 without using the hinge mounting holes 11b. It is also possible to carry out in this manner. In order to further increase the assembling strength of the lock mounting plate 21 in the implementation of the present invention, for example, the lower lock mounting plate 21 shown in FIG. 1 is extended to the lower hinge opening holes 11b. The extended end portion may be fixed to the front surface of the storage main body 11 by using both hinge mounting holes 11b at the lower end.
