On the other hand, the tray 5 has a recess 23 which can accommodate the protrusion 21 corresponding to the protrusion 21 of the guide rail 17 on the lower surface of the portion introduced into the slit 15, and the upper surface of the circuit breaker 18. A raised portion 24 that can be accommodated in the cutout portion is provided corresponding to the cutout portion 22.
[0018]
As shown in FIG. 4 or FIG. 5, the tray 5 is formed by integrally placing mounting portions 5 </ b> B and 5 </ b> C having concave cross sections on both sides of the portion introduced into the slit 15 as a partition portion 5 </ b> A. As shown in FIG. 1, one of the mounting parts 5B has a double structure, and as shown in FIG. 1, a heated food such as boiled food or fried food is placed on it, The mounting portion 5C is used for cold storage stored in the cold storage chamber 10 so that salad or other non-heated food can be placed thereon.
[0019]
Here, the partition portion 5A has a cross-sectional shape suitable for the guide rail 17 and is raised on the upper side, and the above-described recess 23 is formed on the lower surface thereof, and the above-described raised portion 24 is formed on the upper surface thereof. Is formed. Further, projecting portions 25 and 26 are integrally formed on the lower surfaces of the placing portions 5B and 5C and the side edges of the tray 5, respectively. The protruding portions 25 formed on the lower surfaces of the mounting portions 5B and 5C are portions that are supported by contact with the shelf plate 16 shown in FIG. 1, and the protruding portions 26 formed on the side edges thereof are the trays 5. This is for forming a gap between them when they are overlapped with each other.
[0020]
On the other hand, as shown in FIG. 6, the recess 23 and the raised portion 24 are streamlined with a gentle spherical surface.
[0021]
Here, in order to perform the layout work using the layout car configured as described above, the door 7 of the storage 4 is first opened, and the trays 5 on which foods are placed from both sides are sequentially placed inside the storage 4. At this time, a heated food such as boiled food or fried food is placed on one placing portion 5B of the tray 5 and a non-heated food such as a salad is placed on the other placing portion 5C. 5C is faced to the cold storage room 9 and the cold storage room 10, respectively, and the partition part 5A is introduced into the slit 15 of the partition wall 8 from one end side in this state. Then, the tray 5 advances to the back side of the slit 15 while pushing up the circuit breaker 18. In particular, as shown in FIG. 7, the tray 5 advances while the lower surface of the partition portion 5 </ b> A is in point contact with the protrusion 21 of the guide rail 17, and the raised portion 24 provided on the upper surface of the partition portion 5 </ b> A is the lower surface of the circuit breaker 18. It will proceed while making point contact. Therefore, the tray 5 can be smoothly introduced with little friction of the partition portion 5A with respect to the guide rail 17 and the circuit breaker 18, and the partition portion 5A is not in contact with the packing R, so that the packing R is less worn. Moreover, since the protruding portions 25 on the lower surfaces of the placing portions 5B and 5C move while making point contact with the shelf plate 16, the introduction is smoother, and each portion of the tray 5 is less likely to be damaged.
[0022]
Thus, when the tray 5 advances to a predetermined position, as shown in FIG. 8, the projection 21 of the guide rail 17 is received in the recess 23 and the raised portion 24 is received in the notch 22 of the circuit breaker 18, respectively. In this state, the tray 5 is stored in the storage 4. At this time, the tray 5 is separated and stored in the cold storage chamber 9 and the cold storage chamber 10 in a state in which the partition portion 5A is supported by the guide rail 17 and the placement portions 5B and 5C are supported by the shelf board 16.
[0023]
Therefore, the door 7 is closed and the service car is operated to the destination, and when the destination arrives, the door 7 is opened and the tray 5 is taken out from the opening 6 in order. 4 can be arranged on both sides. Even when the tray 5 is taken out, the tray 5 moves while making point contact with the guide rail 17 and the circuit breaker 18 with the protrusions 21 and the raised portions 24, so that the removal operation is smooth and the tray 5 is taken out. After the circuit breaker 18 is lowered, the protrusion 21 of the guide rail 17 is accommodated in the notch 22, so that the slit 15 is sealed and convection does not occur between the warm chamber 9 and the cold chamber 10. Each can be kept at an appropriate temperature.
[0024]
Here, as shown in FIGS. 7 and 8, the protrusion 21 of the guide rail 17 is a streamline having a gentle spherical surface like the raised portion 24 of the tray 5, and the notch 22 of the circuit breaker 18 is also formed on the tray 5. Since it is streamlined with a gentle spherical surface like the recess 23, the projection 21 and the recess 23, the notch 22 and the raised portion 24 have a high buffering effect in fitting and detaching, and the tray 5 can be taken out reliably. . 7 and 8, reference numerals 27 and 28 denote receiving guides attached to one end of the guide rail 17 and the circuit breaker 18, respectively. The receiving guides 27 and 28 appropriately introduce the tray 5 into the slit 15. Can do. Since the receiving guides 27 and 28 have a width that protrudes from between the doors 7, the doors 7 do not prevent the opening 6 from being sealed.
[0025]
As described above, the application example of the present invention has been described. However, as a structure of the storage, the rooms adjacent to each other through the partition wall 8 may be a warm room and a room temperature room, or a cold room and a room temperature room. Moreover, although it is optimal to use the tray 5 as described above, a conventional tray in which the partition portion 5A does not have the recess 23 and the raised portion 24 can also be used.
[0026]
However, the optimal embodiment of the present invention is provided with a storage for storing a tray with a mounting portion connected via a partitioning portion at the top of a chassis having wheels, and the inside of the storage is divided by a partition wall. In the distribution vehicle, horizontal slits are provided in parallel from the end face of the partition wall at a predetermined interval, and the tray is stored in multiple stages by introducing the partition portion into the slit. In addition, a guide rail that supports the partition of the tray is laid on each of the sections, and a breakable circuit breaker that opens and closes the slit facing the guide rail is provided on the upper surface of the guide rail in the longitudinal direction. Protrusions are provided at a required interval, and a cutout portion is formed on the lower surface of the circuit breaker so as to face the projections, and the projections are received. To form a housing capable of recesses the projections by a catering vehicle provided with a housing capable of ridges notch portion corresponding to the cutout portion of the circuit breaker on the upper surface thereof.
[0027]
【The invention's effect】
As is apparent from the above description, according to the present invention, since the protrusions are provided on the upper surface of the guide rail at a required interval, when the tray is stored in the storage case or taken out of the storage case, the partition portion becomes the guide rail. It moves while being supported by the protrusions. Therefore, the tray can be stored and taken out smoothly, and the lower surface of the partition portion can be prevented from being damaged as much as possible.
[0028]
In addition, since the notch is formed on the lower surface of the circuit breaker so as to face the protrusion of the guide rail, the upper surface of the guide rail and the lower surface of the circuit breaker are in close contact with each other when the tray is not stored, so that the slit can be reliably sealed.
[0029]
Furthermore, in the partition portion of the tray introduced into the slit, a recess portion is provided on the lower surface corresponding to the protrusion of the guide rail, and a raised portion is provided on the upper surface corresponding to the notch portion of the circuit breaker. Since the raised portion of the upper portion moves while contacting the lower surface of the circuit breaker, the tray can be stored and taken out more smoothly, and the upper surface of the partition portion can be hardly damaged.
