BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment in which the present invention is applied to a hot and cold serving car will be described with reference to FIGS. 1 to 5.
As shown in FIG. 1, the hot / cold serving car of this embodiment includes a serving car main body 1 (hereinafter, simply referred to as a main body) formed of a rectangular insulated box having front and rear openings. The interior of the main body 1 is divided into two rooms in the left and right direction by a heat insulating wall (not shown), and each room is further divided into two right and left by a heat insulating partition wall 2. However, a refrigerating room 4 is formed on the inner side, and the adjacent refrigerating room 3 and the refrigerating room 4 form a pair, and each of them is equipped with a double door 5.
A machine room 7 is provided on the upper surface of the main body 1, and two refrigerating rooms 4 are cooled by a common refrigeration unit (not shown) provided in the machine room 7. To be heated.
[0006]
A shelf 9 is formed in a plurality of stages in the storage room 3 and the storage room 4 forming a pair. The tray 10 is configured such that food provided in a warm state and food provided in a cold state are separately placed on both sides of the boundary 10A, and the tray 10 is placed on the boundary 10A. By being placed on the shelf 9 while penetrating the partition wall 2 at the location of 10A, the hot food placed on one tray 10 is stored in the refrigerator compartment 3 and the cold food is stored in the refrigerator compartment 4 respectively. Storage or refrigeration is performed.
[0007]
Around the upper and lower ends of the main body 1, bumpers 12, 13 made of synthetic resin are provided so as to protrude, respectively. In addition, a moving wheel is provided on the bottom surface of the main body 1. These wheels are free wheels whose directions can be freely changed, for example, at both ends in the depth direction on one side in the length direction (left side in the figure) and almost in the center in the depth direction on the other side in the length direction. 15 are provided, and fixed wheels 16 are provided at both ends in the depth direction at the center in the length direction.
These wheels 15 and 16 are antistatic wheels and are formed by mixing a conductive material into urethane resin, for example.
[0008]
Then, by being pulled or pushed by a handle 19 provided in the accommodating recess 18 on both the left and right sides of the main body 1, the main body 1 can be moved substantially along the length direction. As shown in FIG. 2, the lower bumper 13 is cut off at the central portion in the length direction of the side edge where the pair of free wheels 15 is provided. A pedal lock 22 for locking in a stopped state is provided. The pedal lock 22 is of a known pedaling type.
[0009]
In this embodiment, an antistatic mechanism for static electricity is provided, which will be described below.
As shown in FIG. 3, the pedal lock 22 is provided on the lower surface of a box-shaped bracket 25 having an open upper surface, and flanges 26 provided on both left and right edges of the bracket 25 are provided on the bottom surface of the main body 1. Of the lower bumper 13 described above, and is fixed by tightening a bolt 28 (see FIG. 2) through four convenient insertion holes 27 formed in the flange 26. I have.
[0010]
The antistatic member 30 includes a stainless steel wire 31 and a mounting member 32 made of a conductive metal plate.
The mounting member 32 is formed in an angled vertically long shape, and includes an upper surface plate 35 in which an insertion hole 34 for the bolt 28 is opened. The mounting member 32 has an insertion hole 34 on the upper surface aligned with an insertion hole 27 on the far right side of the bracket 25 while one surface thereof is in contact with the right side surface of the bracket 25 of the pedal lock 22, and is fastened together with the bolt 28. As a result, it is fixed in a hanging manner from the flange 26 of the bracket 25. At this time, as shown in FIG. 2, the lower end of the attachment member 32 is located a predetermined dimension above the travel location R of the catering car.
[0011]
The wire 31 is attached to the front surface 36 of the attachment member 32 described above. The mounting structure of the wire 31 is as shown in FIGS. Two upper and lower insertion holes 37 are formed in a mounting surface 36 of the mounting member 32, and a mounting bolt 38 is provided to be inserted into the insertion holes 37. A radial through hole 39 is formed in the mounting bolt 38, and after the wire 31 is inserted through the through hole 39 of the mounting bolt 38 with a washer 40 interposed under the head 38A, the mounting bolt 38 is inserted. When the nut 31 is screwed into the hole 37 and screwed to the tip, the wire 31 is sandwiched and fixed between the washer 40 and the mounting surface 36 as shown in FIG.
The wire 31 is fixed with its upper and lower portions fastened by mounting bolts 38 with its lower end protruding below the mounting member 32. The length of the lower end of the wire 31 is such that the mounting member 32 is attached to the bracket 25. It is a length that can be brought into contact with the traveling place R when it is performed.
[0012]
The present embodiment has the above-described structure, and the serving car is moved while rolling the wheels 15 and 16 by pulling or pushing via the handle 19 as described above. At this time, static electricity is generated due to friction between the wheels 15 and 16 and the travel location R, and a part of the static electricity flows from the wheels 15 and 16 to the travel location R or is discharged into the air, but the main body 1 is charged. Tend to be. However, since the wire 31 is provided on the bottom surface of the main body 1 via the attachment member 32 in a grounded state, static electricity flows from the attachment member 32 to the traveling place R through the wire 31 and is charged on the main body 1. That is alleviated.
In particular, the use of the stainless steel wire 31 reduces noise during movement, and also provides excellent durability.
[0013]
In addition, since the installation position of the wire 31 is set in the cutout portion 21 of the lower bumper 13 opened for operating the pedal lock 22, the wire 31 can be easily put in and taken off easily. In addition, since the mounting member 32 is fixed by joint fastening along the bracket 25 of the pedal lock 22, the mounting space can be reduced.
Further, since the wire 31 is grounded by protruding only a small dimension from the lower end of the mounting member 32, the swing width is restrained by the mounting member 32 even when the catering car is moving, and the swing width is suppressed, and the wire 31 may be entangled with the wheel 15. There is no.
