Further, casters 9 are attached below the four corners of the floor surface 14 of the main body portion 7. Then, in the storage space 10 formed in the main body portion 7, on the floor surface 11, is placed a pack 15 in which heat-retaining objects such as food are stored, for example, a pack 15 in which curry, stew, etc. are stored. A large number of cases 16 are arranged in front, back, left and right, and are stacked in a multi-tiered manner. The floor surface 11 of the storage space 10 can be raised and lowered under such a condition.

That is, the heat insulating case is provided with a lifting device 19 for lifting and lowering the floor surface 11 of the storage space 10 through the link mechanism 18 in the jack 17, and the jack 17 attached below the main body 7. It comprises a drivable operating means 20 and a temperature source 21 built in the main body 7 for sending hot air or cold air to the storage space 10.

To describe these in detail, first, as shown in FIG. 1, FIG. 2 (2), FIG. 4 (1), etc., the operating means 20 is forward from below the floor surface 14 of the main body 7. The pedal 22 that is projected to the side, and the parallel link 23 that holds the pedal 22 and that is interposed between the pedal 22 and the jack 17 operation portion of the elevating device 19, and between one of the parallel links 23 and the main body portion 7. And a spring 24 interposed. When the pedal 22 is pushed down by the foot against the pulling force of the spring 24, the jack 17 is smoothly and stepwisely driven forward through the parallel link 23, and the floor surface 11 of the storage space 10 is raised stepwise. I am going to go. In this way, the jack 17 is driven by the operating means 20, but when the foot is removed from the pedal 22, the pedal 22 is raised, returned, and held to the original height level by the tensile force of the spring 24. It has become. For the lowering of the floor surface 11, a release mechanism (not shown) attached separately is used to drive the jack 17 to remove water pressure or hydraulic pressure and drive it backward. However, a pedal 22 is provided side by side to raise one side. It is also conceivable to drive the jack 17 forward and backward with the other one for lowering.

The jack 17 of the lifting device 19 is composed of, for example, a foot-operated hydraulic or hydraulic jack cylinder as described above, and is vertically installed in the lower portion of the main body 7 below the floor surface 11. Then, as described above, the hydraulic pressure is supplied every time the pedal 22 is pushed down, and the rod 25 is stepwise forwardly driven, that is, lifted at every predetermined stroke, and the lifted stroke is expanded through the link mechanism 18. , The floor surface 11 is raised, and the rod 25 is driven backward by the releasing mechanism in accordance with these, so that the floor surface 11 is lowered via the link mechanism 18.

The link mechanism 18 thus interposed between the jack 17 and the floor surface 11 is as follows. That is, the link mechanism 18 is provided on each of the left and right side surfaces of the main body portion 7, and as shown in FIG. 1, the link mechanism 18 is fixed to the rod 25 of the jack 17 and extends to the left and right. , The left and right horizontal pin-shaped joints 27 fixedly connected to the ends of the arms 26 and the other joints 28, which are vertically arranged with respect to the joint 27, as shown in FIG. It is provided with a total of four links 30 which are pivotally attached and are pivotally attached by three pins at each end by a total of six pins 29 and which are vertically crossed in two stages in an X-shape.

Further, as shown in FIGS. 1 and 2 (1) and FIG. 4 (1), etc., vertical rails 31 are vertically fixed to the center of the inner surface on both side surfaces of the main body 7. The above-mentioned joints 27 and 28 are vertically guided by the vertical rail 31 via rollers 32 as shown in FIG. 3 (2) and the like. Further, as shown in FIG. 1, FIG. 2 (1), FIG. 3 (4), etc., a horizontal rail 33 is laterally fixed to the side surface of the main body portion 7 at the lower part of the inner surface. Horizontal rails 34 are also laterally fixed to the lower part of the upper floor 11, and the two parallel horizontal rails 33 and 34 guide the pin 29 of the link 30 to the left and right via rollers 32. Is becoming. That is, the upper two of the pins 29 of the link 30 are guided by the horizontal rails 34 under the floor 11 via the rollers 32, and the lower two of the pins 29 of the link 30 are connected to the main body 7 side. The horizontal rail 33 is guided by rollers 32. In FIG. 3 (2), (3), (4), etc., 35 is a bearing, and this bearing 35 is interposed between each link 30 and the joint 27 or the pin 29.

Reference numeral 43 in FIG. 1 denotes an exhaust port, and this exhaust port 43 is attached to the top of the main body 7 or the upper lid 8 above the storage space 10 so that the warm air blown into the storage space 10 as described above can be discharged. , After the fact, it is designed to be released outside. The exhaust port 43 can be appropriately narrowed in its ventilation range. Further, although the electric heater 39 is used as the temperature source 21 in the illustrated example, the present invention is not limited to this, and various temperature sources 21 can be adopted, such as dry ice, It is conceivable to store this in the freezer and circulate the cool air to the storage space 10.

The heat insulation case according to the present invention is as described above. Therefore, it becomes as follows. In this heat insulating case, a storage space 10 is formed in a box-shaped main body portion 7, and the storage space 10 is formed by opening and closing the upper lid 8 of the opening 6 on the upper surface and the front lid 13 of the opening 12 on the front surface. 10 and the floor surface 11 stores and takes out heat-retaining objects such as food. Further, in this heat insulation case, warm air is sent from the temperature source 21 such as the heater 39 built in the main body 7 to the storage space 10, so that the heat insulation target object stored in the storage space 10 is kept warm. Also, it can be freely run, moved, and transported by the casters 9 attached below the main body 7. Further, the floor surface 11 of the storage space 10 of the heat insulating case is moved up and down by the operation of the pedal 22 of the operation means 20 as needed, through the jack 17 of the elevating device 19 and the link mechanism 18, and its height is freely adjustable. It is variable. Therefore, in this heat insulation case, the following 1st, 2nd, and 3rd are obtained.
