Abstract

PROBLEM TO BE SOLVED: To provide a serving cart with storage whose handle for operation doesn't protrude from a side of the cart main body. SOLUTION: A storage dent 81 is formed on a side surface of the cart main body 1, and bearings 82 whose height can be adjusted in two steps are attached to the front and rear sides of the storage dent 81. A handle 80 is upper-side-open rectangular, and both ends are rotatably supported by the bearings 82. A user can move the cart by rotating and taking out the handle 80 by hand from the storage dent 81, and pulling the handle. When the handle 80 is rotated upward, it hits against stoppers 90 on the upper parts of the storage dent 81, and by keeping pushing the handle 80, the cart can be moved. When the user releases his/her hold of the handle 80, the handle 80 rotates to the hanging position by its own weight and is stored right in the storage dent 81 again. The impact of the handle 80 when it rotates to the hanging position is absorbed as it bumps against a shock-absorbing material 89. Therefore, the handle 80 doesn't hit against a wall, etc., when it is not used, and a door 50B of the cart can be opened by putting it just to the side surface 1B.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment in which the present invention is applied to a hot and cold serving car will be described below with reference to FIGS. As shown in FIG. 1, the hot / cold serving car according to the present embodiment includes a storage room main body 1 (hereinafter, simply referred to as “main body”) configured as a rectangular box as a whole. The base 2 is installed on a base 2 having a large planar shape and also serving as a bumper, and casters 3 are provided at four corners on the bottom surface of the base 2. A machine room 5 is provided on the upper surface of the main body 1, and the bottom of the machine room 5 is slightly larger than the main body 1 and also serves as a bumper. Is an inclined surface. The main body 1 has a shape in which both front and rear surfaces are open, and is configured as a heat insulating box body in which a heat insulating material such as urethane foam is filled in a ceiling wall, a bottom wall, and left and right side walls.

The upper surface of the bottom wall 1A is formed as a flat surface with no steps. Explaining the front and rear end shapes of the bottom wall 1A, as shown in FIG. 2, the edge of the interior bottom plate 7 is bent at a right angle downward after a predetermined width portion is folded on the lower surface side. I have. On the other hand, the edge of the exterior bottom plate 8 is bent upward at right angles. The front plate 9 has a shape in which the upper end is bent twice at right angles. These are made of stainless steel plate.

The upper surface 9A of the front plate 9 is placed under the folded surface 7A of the interior bottom plate 7 with a spacer plate 10 made of a synthetic resin such as ABS resin or rubber interposed therebetween. A hanging surface 9 </ b> B is fixed on the surface of the hanging surface 7 </ b> B of the interior bottom plate 7 with screws 11. On the other hand, the lower end of the front plate 9 is superimposed on the surface of the rising surface 8A of the exterior bottom plate 8, and is fixed by rivets 12. The bottom wall 1A is formed by foam-filling the heat insulating material 13 between the two bottom plates 7, 8 and the front plate 9 assembled in this manner, and in particular, a step is formed at the end of the upper surface of the bottom wall 1A. The shape without the gap is realized. The meaning of sandwiching the spacer plate 10 is to prevent heat from being conducted from the interior bottom plate 7 to the front plate 9 and the exterior bottom plate 8 as much as possible. In addition, the end of the upper surface of the bottom wall 1A has a structure in which the interior bottom plate 7, the spacer plate 10, and the upper surface 9A of the front plate 9 are overlapped with each other, so that the structure has a high strength.

As shown in FIG. 3, vertical frames 14 are respectively set up at the center in the width direction of the front and rear openings of the main body 1. Also, an intermediate wall 15 is provided in the center of the main body 1 in the width direction, and the inside is divided into two right and left chambers. Further, in the two chambers on the left and right, a heat insulating partition wall 16 is provided at a position slightly closer to the intermediate wall 15 side than the center in the width direction. Thereby, the intermediate wall 1
The refrigerator compartment 18 is formed on both sides of the refrigerator 5, and the refrigerator compartment 19 having a slightly larger frontage than the refrigerator compartment 18 is formed outside the partition wall 16 of each refrigerator compartment 18.

As shown in FIG. 5, the vertical frame 14 has a heat insulating material 13A made of polystyrene foam inserted into a front frame 21 having a U-shaped cross section, and a decorative frame 22 having a slightly larger U-shaped cross section is fitted on the back side thereof. It has a prismatic structure. Then, as shown in FIG. 2, a mounting plate 21 </ b> A bent inward is formed on the lower edge of the front frame 21.
Upper surface 9A of front plate 9 constituting the front edge of bottom wall 1A described above.
The vertical frame 14 is fixed on the bottom wall 1A by driving the rivets 23 between the bottom wall 1A and the rivet 23. Therefore, as shown in FIG. 3, there is no step around the lower end of the vertical frame 14. When the rivet 23 is driven between the upper surface 9A of the front plate 9 and the bottom wall 1A of the vertical frame 14, the spacer plate 10 is compressed and adheres to the folded surface 7A of the interior bottom plate 7, so that it is assumed that Even if dew condensation occurs on the surface of the vertical frame 14 and the dew water flows down, it is possible to prevent the dew water from entering the gap between the interior bottom plate 7 and the front plate 9.

The intermediate wall 15 is composed of two ducts 25 for cooling air distribution. This duct 2
As shown in FIG. 4, reference numeral 5 denotes a vertically long, deep-bottom groove-shaped main body portion 26 and a vertically long, shallow-bottom groove-shaped lid portion 27. Is formed in the shape of a hollow prism by covering an appropriate part of the side edge with a screw. These two ducts 25
As shown in FIG. 5, they are spaced apart from each other and are also arranged between the vertical frame 14 and the front and back with an interval therebetween. As shown in FIGS. Is fixed to the bottom wall 1A by rivets 28. Thereby, the duct 25
(See FIG. 3). On each of the left and right surfaces of each duct 25, a group of vents 29 is formed, each of which is vertically divided into seven stages in the drawing. A cool air guide 30 that guides cool air to the left and right refrigerating compartments 18 from the inside of the duct 25 through the vent groups 29 is mounted on the inner surface side of each of the vent groups 29.

Therefore, when the refrigeration cycle is operated and the in-compartment fan 34 is driven, the cool air generated in the vicinity of the cooler 32 is blown into each duct 25 by the in-compartment fan 34 and descends in the duct 25. Meanwhile, the cold air blown out to the left and right refrigerating compartments 18 through the cold air guide 30 and the vent group 29, and then blown out to the right refrigerating compartment 18 continuously rises in the right refrigerating compartment 18 and is further blown out to the left refrigerating compartment 18. The cool air flows through the gap between the two ducts 25 and the gap between the vertical frame 14 and the right refrigerator compartment 18 and then rises in the same manner, thereby generating a circulating flow such that the cool air is guided from the suction port 33 to the cooler compartment 31. Thus, the left and right refrigerating compartments 18 are cooled. As shown in FIGS. 2 and 4, a tank 35 for receiving defrost water is removably accommodated in the bottom of one duct 25.

As shown in FIGS. 1 and 3, the partition wall 16 is formed by stacking and connecting seven unit partition walls 38 as shown in FIG. Have been. The base 37 and the unit partition wall 38 are roughly formed by covering a metal core with a plastic shell having low thermal conductivity, for example, and have heat insulation. As shown in FIG. 6, the base 37 of the partition wall 16 applies the horizontal portion of the L-shaped bracket 40 fixed to the lower portion of the inner surface of the outer shell 37 </ b> A to the interior bottom plate 7 of the bottom wall 1 </ b> A, and attaches the mounting plate 41. It is fixed by screwing or riveting through. Therefore, there is no step around the lower end of the partition wall 16. In addition, as shown in FIG.

On the front and rear end surfaces of the unit partition wall 38, two left and right magnetic metal plates 44 are provided.

Although not described in detail, heating chambers are formed on the left and right side walls of the main body 1, and warm air generated by a heating body accommodated therein is circulated and supplied to the respective heating chambers 19 by a fan or the like. It is supposed to be. On both left and right sides of both ducts 25 constituting the intermediate wall 15, a tray receiver 45 formed by bending a metal pipe is attached in a horizontal posture protruding to the left and right refrigerator compartments 18 over seven steps. The mounting position is a position slightly below each insertion groove 39 in the partition wall 16. On the other hand, the same number of tray receivers 45 are attached to the side walls of both storage compartments 19 at the same height.

As shown in FIG. 1, the tray 46 is formed of a plastic material or the like into a horizontally long rectangular shape, and a boundary portion 46A is provided at a position slightly closer to one side than the center of the width.
The food provided in a cold state is placed on the narrower side of the boundary 46A, and the food provided in a warmer state is placed on the wider side. In the tray 46, the boundary portion 46A has a partition wall 1A.
6 is inserted into the insertion groove 39, and the lower surfaces at both ends are pushed in while being received by the tray receiver 45, and the storage is completed when the stopper 43 is hit. As a result, the cold food placed on one tray 46 is stored in the cold storage room 18 and the hot food is stored in the hot storage room 19, respectively, so that the cold food is stored or refrigerated.

Next, the door device will be described. The front and rear openings of the main body 1 have four doors 50A and 50, respectively.
B is equipped. The two doors 50A in the center are the refrigerator compartment 1
8, and are opened and closed with the vertical frame 14 as a swing center, as will be described in detail later. On the other hand, the two outer doors 50B are for the warming room 19, are respectively supported on the left and right side edges of the opening of the main body 1, can be opened outward, and can be opened around the side surface 1B of the main body 1. Have been. When the doors 50A and 50B are described in common, they are referred to as a door 50.

The door 50 is, as shown in FIG.
, A handle frame 51A, two horizontal frames 52, and two window plates 53 made of a transparent resin plate or glass plate. The one vertical frame 51 and the two horizontal frames 52 excluding the handle frame 51A are formed into a cross-sectional shape as shown in FIG. 8 by extruding an aluminum material. Two fitting grooves 54 for fitting the window plate 53 are formed on the inner surface, and a packing 55 is formed on the back surface on the outer edge side.
Mounting groove 56 is formed. The vertical frame 51 has 45 at each end.
It has been cut every time. The horizontal frame 52 is cut at an end on the side connected to the vertical frame 51 at 45 degrees, while the opposite end is cut at a right angle and only the inner corner is cut at 45 degrees. The handle frame 51A is similarly formed into a cross-sectional shape as shown in FIG. 9 by extruding an aluminum material. The handle frame 51A has the three frames 5 described above.
1 and 52, two fitting grooves 54 for fitting the window plate 53 are formed on the inner surface, and a mounting groove 56 for the packing 55 is formed on the back surface on the outer edge side. In addition, a handle portion 57 is recessed at the center in the width direction on the front side. Both ends of the handle frame 51A are cut at right angles, and only the inner corner is cut at 45 degrees.

The door 50 is assembled in the following manner. First, one vertical frame 51 and two horizontal frames 52 are assembled. In this case, as shown in FIG.
The oblique connection ends of the horizontal frame 52 and the horizontal frame 52 are abutted while inserting a corner 58 formed at a right angle into the inside, and the corner 5
8 are connected to each other by screwing, and assembled in a U-shape. Next, the window plate 53 is fitted over the fitting grooves 54 of the frames 51 and 52. Subsequently, the handle frame 51A is assembled.
A corner 60 is prepared in which an insertion piece 62A to be inserted into the horizontal frame 52 and an insertion piece 62B to be inserted into the handle frame 51A are formed so as to be perpendicular to each other. Then, both insertion pieces 62A and 62B of the corner 60 are inserted into the ends of the horizontal frame 52 and the handle frame 51A, respectively, and the ends of the both frames 52 and 51A abut the respective oblique corners. The handle frame 51A is brought into contact with two surfaces forming a right angle, and is screwed to the corner 60.
And the ends of the upper and lower horizontal frames 52 are connected to each other. Then, the packing 55 is fitted over the entire circumference of the mounting groove 56 on the back surface side, and the door 50 is completed.

The door 50B on the side of the storage room 19 is formed wider because the frontage of the storage room 19 is wider than that of the refrigerator room 18. Each frame 5 constituting these doors 50
The surfaces of 1, 51A and 52 are coated with a resin. This is because aluminum has a high thermal conductivity, so that a heat insulating effect is ensured so that the cold heat of the cold storage room 18 or the warm heat of the hot storage room 19 does not easily escape to the outside.

Further, the support structure of each door 50 will be described.
Hereinafter, only the front side will be described, but the same applies to the rear side. The two doors 50A on the refrigerating room 18 side are swingably supported on the vertical frame 14 side in a posture in which the handle frame 51A is disposed outside. Therefore, as shown in FIG. 10, hinge plates 64 are fixed to the bottom surface of the bumper portion 5A of the machine room 5 and the position immediately before the vertical frame 14 on the upper surface of the base 2, respectively. The upper hinge pin 65 projects downward, and two lower hinge pins 65 project upward from the lower hinge plate 64. On the other hand, the inner end of the upper and lower edges of the door 50A is slightly
A bearing bracket 66 protruding from the front surface side is fixed in a slightly floating state via a spacer 67, and a bearing hole 68 is opened in each protruding portion of the bearing bracket 66.

Therefore, the door 50A is provided with the upper and lower bearing holes 68.
Are swingably supported by inserting the corresponding hinge pins 65. The door 50A is a vertical frame 1
4. The upper and lower edges of the main body 1 and the metal plate 44 of the partition wall 16
, The packing 55 attached to the peripheral edge on the back side is brought into contact, and the opening is closed so that the surface 70 (the surface of the frame) is parallel to the opening surface. Here, in particular, as shown in FIG. 11, the axes of the upper and lower hinge pins 65 are aligned with the closed door 5.
It is set so as to be located on the same plane as the surface 70A (the surface of the frame) of 0A.

Thus, for example, the left door 50 in FIG.
When A is swung counterclockwise in FIG. 12 around the hinge pin 65, as shown in FIG.
The left door 50A can be opened 180 degrees so that the surface 70 of the left door 50A overlaps the surface 70 of the right door 50A. Here, for example, if the hinge pin 65 is at a position retracted to the opening side from the surface 70 of the closed door 50A, it hits the surface 70 of the other door 50A before opening one door 50A 180 degrees. Conversely, the hinge pin 65
Can be opened by 180 degrees, but the amount of protrusion of the hinge pin 65 increases. That is, the door 50A can be opened 180 degrees so that the one door 50A overlaps the other door 50A while minimizing the protrusion of the hinge pin 65 to the near side.

As shown in FIG. 10, around the lower hinge pin 65, a hinge collar 71 having a cam surface with projections arranged at 90-degree intervals is mounted in a non-rotating manner, while the lower hinge pin 65 is mounted. A hinge collar 72 having a cam surface that engages with the above-described cam surface is mounted on the hole edge of the bearing hole 68 so as to be opposed to each other and not to rotate. And both hinge collars 7
The cam surfaces 1, 72 are in a state in which the door 50A is closed,
OA is set so as to engage with each other in a state where it is fully opened 90 degrees and a state where it is fully opened 180 degrees. That is, when the door 50A is swung about the hinge pin 65, the hinge collars 71 and 72 rotate relative to each other, get on and off the cam surface, and are opened and closed while ascending and descending. Doors 50 mesh with each other
A is in a lowered state, and functions to lightly position at those positions. The spacer 67 is engaged with the bearing bracket 66 as described above because of the door 50A.
Is moved up and down, the hinge pin 65 is inserted into the bearing hole 68 while the hinge pin 65 is
This is to avoid interference.

Next, the support structure of the door 50B on the storage room 19 side will be described. First, as shown in FIG. 1, column-shaped door guards 73 are provided on both front and rear left and right edges of the main body 1 over substantially the entire height between the bumper portion 5 </ b> A of the machine room 5 and the base 2. Between this door guard 73 and the above-mentioned door 50A on the refrigerator compartment 18 side, the door 50B on the warming compartment 19 side is arranged with the handle frame 51A brought inside. The door guard 73 has its outer two orthogonal surfaces flush with the surface 70 of the closed door 50B and the side surface 1B of the main body 1 as described later, and the corners are rounded. . The purpose of providing the door guard 73 is to prevent an impact from acting on the door 50B when a corner portion of the main body 1 is hit. It is detachable so that only the guard 73 can be replaced.

The support structure of the door 50B on the right side of the storage compartment 19 on the front side will be described below. As shown in FIG. 13, hinge plates 74 are fixed to the corners of the lower surface of the bumper portion 5A of the machine room 5 and the upper surface of the base 2, respectively. From the lower hinge plate 74 to the lower hinge pin 75
Are projected upward. On the other hand, the outer ends of the upper and lower edges of the door 50B extend to the position of the hinge plate 74, and the extended end is slightly extended to the door 50B.
Bearing bracket 76 projecting toward the surface 70
Are fixed in a slightly floating state via a spacer 77. The protruding portions of the bearing bracket 76 are each provided with a bearing hole 78.

Therefore, the door 50B is provided with the upper and lower bearing holes 78.
Are swingably supported by inserting the corresponding hinge pins 75 therethrough. The door 50B abuts the packing 55 attached to the peripheral edge on the back side thereof over the side edge, the upper and lower edges of the main body 1 and the metal plate 44 of the partition wall 16, and closes the door 70B. It is flush with the surface 70 of the door 50A on the refrigerator compartment 18 side. Here, in particular, FIG.
As shown in the figure, the axes of the upper and lower hinge pins 75 are positioned on a vertical line where the extension of the surface 70 (the surface of the frame) of the closed door 50B and the extension of the right side 1B of the main body 1 intersect. Is set to

When the door 50B is pivoted counterclockwise in FIG. 15 around the hinge pin 75, the surface 70 of the door 50B is moved to the main body 1 as shown in FIG.
The door 50B can be opened 270 degrees so as to overlap the right side surface 1B of the door. Here, the hinge pin 7
If the position of 5 is other than the above, even if the door 50B cannot be opened by 270 degrees, or conversely, even if it can be opened by 270 degrees, the amount by which the hinge pin 75 protrudes to the near side or the side of the main body 1 becomes large. That is, it is possible to open the door 50B by 270 degrees so that the door 50B overlaps the side surface 1B of the main body 1 while minimizing the protrusion of the hinge pin 75.

Also, around the lower hinge pin 75,
Similarly to the refrigerator compartment 18 side, a hinge collar 71 having a cam surface with convex portions arranged at 90-degree intervals is mounted in a non-rotating state, while the above-mentioned cam surface is provided at the edge of the lower bearing hole 78. A hinge collar 72 having a cam surface that engages is mounted in a counter-rotating state in an opposing manner. The cam surfaces of the hinge collars 71 and 72 engage each other when the door 50B is closed, when the door 50B is opened 90 degrees, when it is opened 180 degrees, and when it is fully opened 270 degrees. Is set. That is, the door 50B is connected to the hinge pin 7
When swinging about center 5, both hinge collars 71, 72
Are rotated relative to each other, and are opened and closed while climbing on and off the cam surface, and the cam surfaces engage with each other at the above-described closed position, 90-degree open position, 180-degree open position, and fully open position, and the door 50B is engaged.
Are in a lowered state, and function so that they can be lightly positioned at those positions. The spacer 77 is engaged with the bearing bracket 76 because of the door 50A on the refrigerator compartment 18 side.
Is the same as

As shown in FIGS. 16 and 17, the left and right side surfaces 1B of the main body 1 are provided with handles 80 for moving the serving truck. The handle 80 is formed by bending a metal bar into a U shape. On the other hand, in the substantially central position of the left and right side surfaces 1B of the main body 1, a rectangular accommodation recess 81 is provided.
Are recessed. A pair of bearings 82 are provided on the front and rear side surfaces of the housing recess 81. This bearing body 8
Reference numeral 2 denotes a structure in which a bearing portion 84 is provided in the center of a vertically long leg 83, and through holes 86 for screws 85 are formed at both ends of the leg 83. On the front and rear side surfaces of the housing recess 81, three screw holes 87 are formed vertically at the same interval as the insertion hole 86 of the screw 85 described above. The bearing body 82
By screwing using the screw holes 87 at the center and the lower side, or the upper and the center, the mounting can be performed in two stages up and down. It is preferable that a dummy screw be attached to the unused screw hole 87.

Both ends of the handle 80 are rotatably supported by bearing portions 84 of the front and rear bearing members 82. Handle 8
Numeral 0 always takes a drooping posture due to its own weight, and at this time, the handle 80 fits completely in the accommodation recess 81 without protruding from the side surface 1B of the main body 1. In addition, a cushioning material 89 made of rubber or the like is provided on the bottom surface of the accommodation recess 81 so as to abut on both arm portions of the handle 80. Further, stoppers 90 are provided at both ends of the upper surface of the accommodation recess 81 so that both arms of the handle 80 can be abutted. The stopper 90 is mounted flush with the side surface 1B of the main body 1. Then, when the handle 80 is turned upward, as shown by the solid line in FIG. 17, both arms come into contact with the stopper 90 to take a predetermined tilting posture.
In addition, as shown in FIG. 1, a storage portion 93 that can store a power cord 92 and the like is provided on one inclined side surface of the machine room 5.
Are recessed.

The present embodiment is configured as described above.
Subsequently, an example of its use will be described. When serving meals in the serving car, the door 50A on the side of the cold room 18 and the warm room 19
The door 50B on the side is opened. The doors 50A and 50B are opened by holding the handle portion 57 and swinging about the hinge pins 65 and 75, and the degree of opening is arbitrary. For example, the door 50A on the side of the refrigerator compartment 18 is connected to the adjacent refrigerator compartment. The door is opened 180 degrees toward the 18 side, and is opened 270 degrees so that the door 50B on the side of the storage room 19 is turned around the side surface 1B of the main body 1.
In this case, the door 50A on the refrigerator compartment 18 side exactly overlaps with the surface 70 of the door 50A on the adjacent refrigerator compartment 18 side,
Since the handle 80 is housed in the housing recess 81, the door 50B on the ninth side also exactly overlaps the side surface 1B of the main body 1 and is positioned by the functions of the hinge collars 71 and 72, respectively. In this state, although the doors 50A and 50B are open, they do not protrude outward, so that work in the surrounding area is extremely easy.

Then, the tray 46 on which the cold food and the hot food are loaded is inserted into the insertion groove 39 of the partition wall 16 and pushed in while being slid on the tray receiver 45 to be accommodated. In this case, since the tray receiver 45 is formed of a metal pipe, the slip is good, and the work of housing the tray 46 can be performed smoothly. In addition, since the tray receiver 45 is formed by bending a metal pipe, the obstruction of the air circulation is minimized. Therefore, before the tray 46 is stored, the refrigerating room 18 is pre-cooled and the refrigerating room 19 is stored. If you want to preheat
Cool air or warm air can be circulated well, and the entire area of the cold room 18 or the warm room 19 can be efficiently pre-cooled or pre-heated. If the adjacent doors 50A on the refrigerator compartment 18 side are opened at 90 degrees each so as to project at right angles from the main body 1, the trays 46 can be accommodated in the left and right rooms at the same time. When the storage of the tray 46 is completed, the door 50 is closed.
When A and 50B are closed, the cold food placed on each tray 46 is stored in the cold storage room 18 and the hot food is stored in the hot storage room 19, respectively, so that the cold food or the hot food is stored.

When moving the serving truck, the power cord 92 is first disconnected. If the power cords 92 are bundled and stored in the storage portion 93 on the side surface of the machine room 5, the power cords 92 are preferably disposed. Then, as shown in FIG. 18, the serving truck can be moved by pulling the handle 80 out of the housing recess 81 while rotating the handle 80 disposed on the side surface 1B of the main body 1 and holding the handle 80 as it is. Further, when the handle 80 is turned upward, as shown in FIG. 19, it hits the stopper 90 and takes a predetermined tilting posture, so that the serving car can be moved by continuously pushing the handle 80. When the serving truck is moved to a desired position and the hand is released from the handle 80, the handle 80 turns to a hanging posture by its own weight, and
It fits perfectly within 1. The impact force at the time of turning to the hanging posture is absorbed by hitting the cushioning material 89. In the case where the refrigerated car is still heated and refrigerated at the destination, the power cord 92 can be connected to an appropriate outlet at the destination to cope with the refrigeration. When serving food, the door 50 should be used as described above.
A, 50B may be opened and the tray 46 may be pulled out.

The serving truck has a tray 46 on which food is directly placed.
Is housed, so the inside is apt to get dirty and it is necessary to clean it frequently. This cleaning,
It is efficient to wipe with a sponge or cloth while sprinkling water with a hose or the like. In this case, in the conventional serving truck, since the cooler is provided in the duct 25 constituting the intermediate wall 15, if the water is applied by the hose, the water may also be applied to the cooler through the vent hole. Could not be watered. In this regard, according to the present embodiment, the cooler 32
Is provided in the machine room 5, and the duct 25 has a structure in which only cool air flows. Therefore, even if water enters the duct 25, the duct 25 is not hung on the cooler 32. It became possible.

When cleaning with water is completed, the wall surface is wiped off with a dry cloth or the like, but water, residue, and the like are particularly likely to remain on the bottom wall 1A. In this case, it is efficient if the bottom wall 1A is wiped with a cloth and swept out from the front or rear opening. However, in the conventional one, the front or rear end structure of the bottom wall 1A has a structure in which a front frame having a U-shaped cross section is fitted outside the edges of the interior bottom plate and the exterior bottom plate. When the water is swept out as described above, water and residues are likely to be trapped and accumulated on the steps, and it has been necessary to carefully wipe off the water and residues. In this regard, according to this embodiment, since the end of the bottom wall 1A has a structure without steps, water, residues, and the like can be cleanly and easily swept from the bottom wall 1A. Also, the bottom wall 1A
The vertical frame 14, the duct 25 and the partition wall 16, which are arranged on the upper surface, are also mounted around the lower end without a step, so that water and residues can be similarly removed neatly. Also, as described above, the tray receiver 4
Since the metal pipe 5 is formed by bending a metal pipe, dust and the like hardly accumulate, and the tray receiver 45 itself and the wall surface to which the tray receiver 45 is attached are easily wiped and cleaned.

As described above, according to the present embodiment,
When not in use, the handle 80 for moving the serving car is accommodated in the housing recess 81 and does not protrude from the side surface 1B of the main body 1, so there is no possibility of hitting a wall or the like. When the door 50B is opened by turning the door 50B toward the side surface 1B,
The tray 46 can be opened in a state in which the tray 46 is in close contact with the tray 46, and the appearance is good. In addition, the handle 80 can be pulled by holding it with a hand, and can be pushed by rotating upward and hitting the stopper 90. Further, since the bearing body 82 supporting the handle 80 can be changed in two stages, the mounting position of the handle 80 can be changed according to the height of the worker and the like, so that the usability is excellent.

<Other Embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition, various changes can be made without departing from the scope of the invention. (1) The position of the handle may be changed in three or more steps, and the height may be adjusted steplessly by using a long hole or the like. (2) The present invention can be similarly applied to a serving car that performs only one of hot storage and cold storage. (3) Further, the present invention is not limited to the serving truck, and can be widely applied to all article storage trolleys provided with wheels on the bottom surface and having an opening with a door on the front surface.
