Abstract

PURPOSE: To open/close a cover which covers a square hole through which the pole of an uncooled rack is inserted with a one touch operation and to preserve by housing an opened cover in the inside of a table board as it is without dismounting from a case main body in a flat open showcase in which the square hole is formed on the upper face of the table board in the case main body. CONSTITUTION: The cover 16 which covers the square hole 9a for uncooled rack mounting opened on the upper face of the table board 9 is formed in a cross-sectional U-shaped channel plate equipped with a lug 16a connected to the edge of the square hole at its tip, and a tiltable cover connected freely openably/closably by inserting supporting shaft pins 17 on a table board 9 side to guide grooves 16b in the longitudinal direction piercing through right and left side walls is formed. In an ordinary operation, the square hole is blocked by drawing out the cover to the upper face side of the table board 9, and when the uncooled rack is mounted, the cover 16 is transferred to an erecting posture setting the shaft supporting pin 17 as a fulcrum, then, it is housed in the inside of the table board 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat open showcase for refrigeration and refrigeration, which is constructed such that an uncooled shelf (optional item) is attached to a table base of a case body.

[0002]

2. Description of the Related Art As a flat open showcase for freezing and refrigerating, there is known a structure in which a non-cooling shelf separately prepared as an option is attached to the upper part of the case body according to the user's request. FIG. 2 is a configuration diagram of such a flat open showcase (double-sided type). In the figure, 1 is an outer box of an open top type case body, 2 is an inner box, 3 is an air curtain blown upright in the center of the cabinet. A center duct, 4 a cold air circulation duct defined between the outer box 1 and the inner box 2, 5 a cooler, 6 a fan, 7 a windshield, 8 a deck pan at the bottom of the inside, 9 a case A table base installed on the top of the center duct 3 along the longitudinal direction of the main body. With such a configuration, the cold airflow that has exchanged heat with the cooler 5 flows through the cool air circulation duct 4 as shown by an arrow in the cool-keeping operation, and is divided into two hands from the air curtain outlet port 3a of the center duct 3 to cool the upper surface of the case body. It is well known that the air curtain is blown out to keep the inside of the refrigerator cool.

In addition, an uncooled shelf 10 represented by a chain line is prepared as an optional item in this type of flat open showcase, and is attached to the upper part of the case body according to the user's request. As shown in FIG. 3, the non-cooling shelf 10 is composed of a pair of left and right shelf columns 11 and a shelf plate 13 that is hung between the shelf columns via a bracket 12.
The shelf support 11 is inserted into the square hole 9a opened on the upper surface of the table base 9 from above, and the tip of the support is fixed to a support frame (not shown) provided inside the center duct 3.

By the way, when the non-cooling shelf 10 is not adopted, the table base 9 is used as a table.
It is necessary to close the square hole 9a opened on the upper surface.
Therefore, conventionally, as shown in FIG. 3, a flat plate-shaped cover 14 that closes the square hole 9a is used as an accessory, and the cover 14 is normally fastened to the upper surface of the table base 9 with a screw 15 to fix the square hole 9a.
It is trying to block.

[0005]

By the way, in the conventional structure in which the cover 14 is screwed and closed in the insertion square hole 9a of the non-cooling shelf which is opened in the table base 9 as described above, the non-cooling structure is used. When the shelves 10 are attached or detached, the fastening screws 15 are operated one by one to remove or attach the cover 14, which is troublesome. Further, the cover 14 removed from the table base 9 needs to be stored separately and may be inadvertently lost.

The present invention has been made in view of the above points, and is intended for a flat open showcase in which a square hole for inserting a column of an uncooled shelf is provided on the upper surface of a table of a case body. You can open and close the cover to close with one-touch operation, and the open cover can be stored and stored directly inside the table base without removing it from the case body, convenient installation of the flat open showcase, especially the square hole cover It is intended to provide a structure.

[0007]

In order to achieve the above object, according to the structure of the present invention, the cover is connected to the support shaft pin provided in the square hole of the table base, and the upper surface of the table base is always provided. It should be configured as a retractable cover that is pulled out to close the square hole and moves to the open position when the uncooled shelf is attached and is stored inside the table base.

The foldable cover is a channel plate having a U-shaped cross section with a handle portion for locking the edge of a square hole at its tip, and longitudinal guide grooves drilled in the left and right side walls of the channel plate. It can be implemented by a concrete structure in which the table support side pivot pin is connected so as to be openable and closable.

[0009]

In the above structure, when the non-cooling shelf is not used, the cover is pulled out to the upper surface of the table to keep the square hole into which the shelf support is inserted, and the shaft is used when setting the non-cooling shelf. Move the cover to the open position while keeping it connected to the support pin and store it inside the table base. Moreover, a set screw is not required, and the cover can be easily opened and closed by one-touch operation. In the open state, the cover is stored inside the table base without being removed from the case body, so there is no risk of loss.

[0010]

Embodiments of the present invention will now be described with reference to FIGS. 1 (a) to 1 (d).
It will be described based on. Square holes 9a for inserting columns of uncooled shelves (see FIGS. 2 and 3) opened on the upper surface of the table base 9
The cover 16 attached so as to close the channel is a channel plate having a U-shaped cross section and having a size corresponding to the opening area of the square hole 9a as shown in the figure. A tongue-shaped handle 16a that engages with the edge of the hole 9a is provided, and slit-shaped guide grooves 16b are formed in the left and right side wall surfaces along the longitudinal direction. On the other hand, at the end of the square hole 9a, a spindle pin 17 as a through pin is installed so as to cross the square hole inside the table base 9, and the spindle pin 17 is passed through the guide groove 16b of the cover 16. Are interconnected.

With such a structure, when the uncooled shelves described above with reference to FIGS. 2 and 3 are not adopted, the cover 16 is placed above the table base 9 as shown in FIGS. 1 (a) and 1 (b). The rectangular hole 9a is pulled out to close the rectangular hole 9a, and the handle 16a is locked and held at the edge of the rectangular hole 9a. On the other hand, when attaching the uncooled shelf to the case main body, first, as shown in FIG. 1B, the cover 16 is rotated upward from the closed position with the support shaft pin 17 as a fulcrum to an upright posture, and then the guide groove. While sliding the spindle pin 17 along 16b, the entire cover is pushed inward of the table base 9 and stored in a vertical posture as shown in FIG. 1 (c). This opens the square hole 9a, and by inserting and fixing the shelf column of the non-cooling shelf into the square hole 9a, the non-cooling shelf is attached to the flat open showcase as shown by the chain line in FIG. You can exhibit and sell.

Although the illustrated embodiment shows a double-sided flat open showcase, it is needless to say that the present invention can be similarly applied to a wall flat open showcase.

[0013]

As described above, according to the structure of the present invention, the cover of the square hole opened on the upper surface of the table base of the case body for connecting the uncooled shelf is connected to the pivot pin as the retractable cover. This makes it easy to open and close the cover with one-touch operation without the need for a set screw, and when the cover is open, the cover is stored inside the table base without being removed from the case body, so there is no risk of loss. It can be improved in terms of handleability.
