Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Field of Application The present invention relates to a locking device for a showcase having a sliding door.

Conventional Technology A showcase is known in which an opening is formed on the front or rear surface, a sliding door is disposed in this opening via a rail, and goods are taken in and out from the opening by moving or removing the sliding door. The sliding doors of showcases are locked during non-business hours such as at night and on regular holidays.This method of locking involves applying a so-called night cover that covers and secures the entire door, and locking mechanisms. It was well known that the door was equipped with a lock to prevent the door from moving. Among them, Japanese Utility Model Publication No. 42-3676 is an example of the latter, in which a lock plate and a cylinder lock are used to prevent the sliding door from being opened or closed.

Problem to be Solved by the Invention When using a night cover as a locking method, although it is possible to reduce the external load, it is necessary to secure a storage place for the night cover when it is not in use. When the storage area is large, it is difficult to secure a storage space, and locking the storage area becomes extremely troublesome.

On the other hand, the locking device disclosed in Japanese Utility Model Publication No. 42-3676 is built into a showcase, and does not require storage or management when not in use. However, since it is stored in a showcase, the storage space for the locking device must be specially partitioned, and since it has no role in opening and closing the door when not in use, the storage space must be
% type was desired.

Therefore, an object of the present invention is to provide a showcase equipped with a locking device that requires less space for installing the locking device and facilitates locking operations.

[Structure of the invention]

Means for Solving the Problems The present invention is a showcase having a door that is slidably held on a rail and has a frame material arranged around its periphery, in which the outer door of the warehouse overlaps with the inner door when the door is closed. A fixed body that is provided to protrude outward from the frame material and has a hole formed therein, and is held by a shaft on a surface perpendicular to the sliding direction of the outside door of the refrigerator, and is rotatable and slidable relative to the shaft. A fitting body having a long hole and a lock hole formed on one end side facing the hole of the fixing body when locked, and a fitting body formed at a suitable location on the outer surface of the refrigerator inner door and having the other end side of the fitting body inward from the outer surface of the refrigerator when locked. A locking device comprising a fitting recess that faces the fitting recess, a lock hole that faces each other when the other end of the fitting body faces the fitting recess, and a lock that is inserted into the hole and restricts movement of the fitting body. It is something.

Action: By rotating and sliding the fitting body held on the surface perpendicular to the sliding direction of the outside door with respect to the shaft body through the elongated hole, its tip (-other end side) is fitted. The fitting body faces the recess and is fitted into the fitting recess to restrict sliding movement of both the inside and outside doors of the refrigerator. At this time, a lock is inserted into the lock hole of the fitting body and the hole of the fixing body to prevent the fitting body and the fitting recess from becoming disengaged, thereby simplifying the locking operation and simplifying the locking device. .

EXAMPLES Examples of the present invention will be described below with reference to FIGS. 1 to 6.

(1) is a refrigerated showcase that has a machine room (2) partitioned by a heat insulating wall at the bottom and a storage room (3) connected to the cooling room at the top, and the front of the storage room (3). And on the rear side, there are a front door (4) and a rear door (
5), and at least the front door (4) is made of a transparent material. In addition, the storage room (3) is partitioned into upper and lower levels by removable shelf members (6) such as net shelves, and the cooling room is equipped with a blower and an evaporator for air circulation. .

The front door (4) and the rear door (5) each have a resin frame member (7) on each of its four sides, and in this example, frame members with the same cross-sectional shape are used on all four sides. It is equipped with a groove (8) that allows the rail to face.

Next, the locking device (11) will be described in detail. Since the showcase (1) of this example has doors at the front and rear, the explanation will be given using the rear door (5>) as an example.

A fitting body (21), which will be described later, is installed at a suitable position on the horizontal frame member (7) of the inner side door (12) or the outer surface (13) of the refrigerator.
A fitting recess (14) in which the tip faces inward from the outer surface of the refrigerator.
has been established.

The fitting recess ( 14
) is located at the same height as the shaft body 16 which also serves as a fixing member.
) is fixed to protrude outward from the outer surface of the refrigerator and has a hole (18) formed in the protruding portion, and a long hole ( 19) and a keyhole (20) corresponding to the hole (18) is formed on one end side, the other end side faces the fitting recess (14) for locking, and its width is equal to or less than the depth width of the frame member (7B). A set fitting body (21) is provided. This fitting body (21) forms a handle part (22) by bending one end thereof, and is arranged on the outside of the fixed body (17), and when unlocked, moves in the same direction as the frame member (7B). It is held in such a way that it does not protrude inward or outward from the frame member (7B), and is held in a direction perpendicular to the frame member (7B) when the lock is locked. (23) is a lock such as a padlock having a locking arm that is inserted into the keyhole (20) and the hole (18).

The above fitting recess (14), fitting body (21), fixed body (1
7), the shaft (16) and the lock 23> constitute a locking device (11). (24) is a spacer that reliably forms a gap (1) for rotating the fitting body (21) when the shaft body (16) is fixed to the frame member (7B).

To explain the locking procedure using this locking device (11), with the rear opening closed with the rear door (5), the fitting body (21) is rotated through the elongated hole (19) with respect to the shaft 16〉. Move the fitting body (21) horizontally along the long hole (19) so that the elongated hole (19) is horizontal (see Figure 5), and move the fitting body (21) horizontally so that the other end is in the fitting recess (14). ), set the fitting body (21) so that it faces inside (see Fig. 6), and then fit the lock arm of the lock (23) into the keyhole (20> and hole (18)) to fix it. In this state is locked, and the inside door (12) and outside JR (15) are in the fitting recess (14).
Since the fitting body (21) faces the two, mutual movement is restricted and sliding movement from side to side along the rail is no longer possible.

In this example, the fixed body (17) is constructed as a separate member from the frame member (7B), but a part of this frame member is extended outward and a hole is formed in this extended part. Alternatively, it may not be held fixed, but may be held so as to be insertable into the plug member, for example. On the other hand, in the fitting body (21), the shape and formation position of the elongated hole (19) are devised so that when the lock is not locked, the fitting body (21) rotates with respect to the shaft body (16) due to its own weight. (See FIG. 4), the locking and unlocking operations become easier.

〔Effect of the invention〕

As described in detail above, according to the present invention, almost no space is required for storing the locking device itself. In addition, by holding the fitting body in the locking device on a surface perpendicular to the sliding direction of the outer door, it is possible to prevent it from protruding outward from the outer door when the door is unlocked, and the fixing body is attached to the frame material so that it does not protrude outward from the outer door. By protruding from the door, it can also be used as a door handle when the door is unlocked. On the other hand, when the tip (-other end side) of the fitting body faces the fitting recess, the lock hole faces the hole in the fixing body, so when locking, both the interior and exterior doors of the vehicle are closed. By setting the fitting body in this state and allowing the fitting body to face the fitting recess, the fixing position of the locking device is defined, making it easy to perform reliable locking. On the other hand, the locking device can be simplified and the locking operation can be simplified.
