Description

[Detailed Description of the Invention] The present invention relates to a prefabricated refrigerator whose trolley can be easily put in and taken out.

Conventionally, the entrance/exit of a prefabricated refrigerator is as shown in FIGS. 8 and 9, in which a side wall panel 3' provided with an entrance 11' is connected to a floor panel 2 using a fastener 5. Since the fastener 5 is fixed to the end edge of the zipper 5 with a fairly deep depth, the entrance 11
It was unavoidable that there was a fairly high partition 16' at the bottom of the doorway 11', and a large step was created at the bottom of the entrance/exit 11'.

Therefore, it is difficult to put the trolley inside the refrigerator.
If the load is forced into the load, a steeply sloped base plate must be used, which is extremely dangerous as the load may collapse or slip and fall.

Furthermore, in order to avoid creating a step at the bottom of the entrance/exit 11', it is possible to use a floor panel with a structure dedicated to the entrance/exit at the edge of the floor panel 2, but in this case, the position of the entrance/exit would be limited. Otherwise, a large number of different types of floor panels would be required, making the prefabricated refrigerator expensive.

The object of the present invention is to eliminate the above-mentioned conventional drawbacks, and to provide an inexpensive prefabricated refrigerator in which there is no step at the lower part of the entrance and exit, making it easy to take in and take out the trolley.

Next, the prefabricated refrigerator of the present invention will be explained with reference to the drawings.

In the figure, 1 is a prefabricated refrigerator that can be assembled at the installation site, and a side wall panel 3 is erected and connected to the periphery of a floor panel 2, and a ceiling panel 4 is connected and placed on top of the side wall panel 3. It is composed of

Each panel is fitted with an adjacent panel in a concave-convex manner, and in the illustrated example, the panels are connected at least two places on each side using panel connecting fasteners 5.

The panel connecting fastener 5 is composed of a male connecting part 6 and a female connecting part 8, and has a latch 7 as shown in FIGS. 2 and 9.
A male connecting part 6 in which a latch 7 is rotatably housed is attached to the lower end of the side wall panel, a latch storage part 9 is provided, and a locking rod 10 for locking the tip of the latch 7 is provided in the storage part 9. The provided female connecting portion 8 is attached to the edge of the floor panel, the male connecting portion 6 and the female connecting portion 8 are brought into contact with each other, and the latch 7 is rotated to close the locking rod. The panels are connected to each other by being locked to the panel 10.

Reference numeral 11 denotes a doorway formed by cutting out the side wall panel 3 until it reaches the bottom edge. A door 12 is attached to one side end of the doorway 11 with hinges 13 and 13 so that the doorway 11 can be opened and closed. Above and on the sides of the doorway 11, vertical frames 14, 14 and an upper frame 15 are formed which contact and seal the periphery of the door 12, and a tread plate 16 serving as the lower frame is placed on the edge of the floor panel 2. It is attached to cover the edge.

As shown in FIGS. 1, 5, and 6, the footboard 16 is formed by bending a thin long plate such as a stainless steel plate at right angles to the longitudinal direction, and has mounting holes 17 drilled at appropriate intervals. It is set up.

The footboard 16 has an upper opening approximately in the shape of a U-shape with a notched lower corner, as shown in FIG. Shape tread mounting fixture 1
8 is inserted into the latch storage part 9 of the female connecting part 8 from the side so as to hold the locking rod 10 in the locking groove 20 and rotated to fit into the latch storage part 9, and then The tread plate 16 is inserted into the mounting screw hole 19.19 provided on the upper end surface of the tread plate fixture 18.
It is screwed by a male screw 21 passing through the mounting hole 17 of the holder.

As shown in FIG. 7, it is made of a long plate with a concave cross section that can fit into the groove 22 for fitting with the side wall panel 3 of the floor panel 2, and has tapped holes bored at appropriate locations. or using the connecting plate 23 to which the nut 24 is welded,
8 through the connecting plate 23, the position of the mounting hole 17 of the tread plate 16 is not limited to the position of the female connecting part 8, and the tread plate 16 is firmly secured to the end. Installed and preferred.

Alternatively, the connecting plate 23 may be fixedly connected to the panel frame or surface plate between the side wall panel 3 provided with the entrance/exit 11 and the lower end. In this case, the side wall panel 3 Since the shape is quadrilateral, the strength is improved compared to a case where the lower part of the entrance is left cut out, which is preferable because it prevents damage during carrying or transportation.

Further, as shown in FIGS. 5 and 7, a space 25 is provided between the footboard 16 and the fitting groove 22 of the floor panel 2 or between the connecting plate 23, and a heater 26 is provided within the space 25. If this is installed, freezing on the treadboard 16 is prevented, and there is no slipping, thereby improving safety.

As mentioned above, the prefabricated refrigerator of the present invention has a floor panel on the upper end surface that holds the locking rod of the upwardly opening approximately U-shaped tread plate fitting fitted into the latch storage part of the female type connecting part constituting the panel connecting fastener. Since a footboard is attached to cover the edge of the floor panel, the footboard can be attached to an appropriate position on the periphery of the floor panel and used as an entrance/exit, and there is no need for a special floor panel for the entrance/exit, making it inexpensive. This also makes it easier to take the cart in and out since there are no steps on the treadle.
