Description

[Detailed description of the invention] This invention relates to a locking device suitable for an under-counter refrigerator equipped with two double doors, and its purpose is to lock both doors at the same time to open the door and remove component parts. The purpose of the present invention is to prevent theft by using a locking lever, and to easily insert/remove and store a locking lever.

Below, an embodiment of the present invention will be explained with reference to the drawings. Reference numeral 1 shown in Figs. Two double-sided insulated doors 3A, 3B that are rotatably supported by a pair of hinges 4A, 4B and close the front opening.
and a removably installed machine room cover 5 are arranged side by side. Reference numeral 6 denotes a stainless steel top table that covers the top surface of the main body and serves as a cooking table.The rear edge is fixed to the back of the main body, and the front edge is lower than the front of both doors as shown in Figures 4 and 5. It is engaged and fixed to an L-shaped metal support plate 7 which also serves as a reinforcing plate and is fixed to the upper front surface of the main body so as to protrude forward. In addition to door switches 8A and 8B that turn on the interior lights when the door is opened, a locking lever to be described later is fixed to this mounting plate. 9 is a torsion coil spring 9
A hinge-type rotating device with A in the center, allowing both doors 3
Gap L formed between doors A and 3B when both doors are closed
The fixing piece 9 is attached to the bottom surface of the support plate 7 so that it is located directly above the
It is attached via B. Reference numeral 10 denotes a locking lever made of an L-shaped thin metal plate with a hole 11 formed at one end that becomes the protrusion 10A, and a rotating device 9 at the other end.
When the door 3A is not locked, it is stored in the gap M between the upper surface of the door 3A and the support plate 7 as shown by the chain line by the repulsive force of the spring 9A of the rotating device 9, and when it is locked, the gap M is fixed. Draw out to L and both doors 3A,
The hole 11 is positioned further forward than the front surface of 3B. In addition, when pulling out this locking lever into the gap L, open the door 3A, rotate the lever downward as shown by arrow A, and then close the door 3A, and when storing it into the gap M, open the door 3A. The door 3A can be closed by rotating the lever upward as shown by the opening arrow B.
12 is a metal lock plate with an elongated hole 13 formed in the center, and the locking lever 1 is inserted through the hole 13.
0 is inserted into the protrusion 10A of both doors 3 than the hole 11.
It is located close to the A and 3B sides and partially covers both doors. Numeral 14 is a lock for inserting and removing a locking arm 14A into the hole 11, and when locked, the locking lever 10 is opened.
The detachment of the lock plate 12 from the lock plate 12 and the opening of both doors 3A and 3B from the lock plate 12 are respectively prevented.

According to such a locking device, a locking lever 10;
Both doors 3 are secured by lock plate 12 and lock 14.
A and 3B can be prevented from being opened at the same time to prevent the food inside the refrigerator from being stolen, and the lock plate 12 can prevent damage to both doors. The locking lever 10 cannot be removed from the rotating device and the rotating device, and not only can opening of both doors 3A and 3B be prevented, but also theft due to removal of the component parts can be prevented. Furthermore, by releasing the lock, the locking lever 10 can be automatically stored in the gap M between the support plate 7 and the door 3A due to the return force of the spring 9A, so when the lock lever 10 is not locked, the gap between the doors 3A and 3B is closed. The locking lever 10 does not protrude from L, which not only improves the design effect of the main body, but also avoids danger to the cook's legs and makes it easier to take food in and out of the refrigerator. Further, when the locking lever 10 is pulled out into the gap L, the side surface of the door 3A on the gap side becomes a stopper for the locking lever 10 which moves upward due to the restoring force, so that the lock plate 12 can be easily attached.

As described above, the present invention allows both double doors to be locked at the same time, making it impossible to remove component parts in the locked state, completely preventing theft of food inside the refrigerator, and using a spring-loaded locking lever. Since it is attached to the support plate via a rotating device, it is not only easy to pull out and store in both gaps, but when the door is locked, one door acts as a stopper for the locking lever, making it easy to install the lock plate. When the door is unlocked, it does not become a protruding object between the two doors, which is desirable in terms of design and avoids danger to the cook's legs.
