<First embodiment>
Embodiment 1 of the present invention will be described with reference to FIGS. In the present embodiment, a hot / cold serving car 10 is exemplified as a cold / hot storage device. As shown in FIGS. 1 and 2, the hot / cold serving car 10 includes an insulating box 11 having a storage room 16, a caster 12 attached to the bottom of the insulating box 11, and a machine room disposed above the insulating box 11. 13 is provided. The heat-insulating box 11 is constituted by a wall portion filled with a heat-insulating material such as urethane foam, and has a rectangular parallelepiped shape in which both sides in the front-rear direction are open as a whole.

  As shown in FIG. 2, in the inner space of the heat insulating box 11, a vertical frame 14 is provided at a central portion in the width direction (the left-right direction and the X-axis direction in FIG. It is erected. An intermediate wall 15 (see FIG. 3) is provided between the pair of vertical frames 14, 14. The inner space of the heat insulating box 11 is divided into right and left by an intermediate wall 15, and is configured as two storage rooms 16 capable of accommodating the tray 25. FIG. 2 shows only the storage room 16 on the left side. In each of the storage chambers 16, a partition wall 30 (described in detail later) extending in the front-rear direction is provided. Thereby, the storage room 16 is partitioned by the partition wall 30 into the refrigerator room 17 and the warm room 18.

  In the present embodiment, the two storage chambers 16, 16 are arranged symmetrically about the intermediate wall 15. That is, in the storage room 16 on the left side shown in FIG. 2, the storage room 18 is arranged on the left side, and the refrigerator room 17 is arranged on the right side. On the other hand, in the right storage room 16 not shown in FIG. 2, a refrigerating room 17 is arranged on the left side, and a warming room 18 is arranged on the right side. Further, the heat insulation box 11 is provided with a double door 19 in a form corresponding to the front-back direction of each storage room 16. Each of the refrigerator compartments 17 and 17 and each of the refrigerator compartments 18 and 18 can be opened and closed by a corresponding door 19.

  The intermediate wall 15 is composed of, for example, a pair of plate-shaped members, and air can flow through the inside. Thereby, the intermediate wall 15 has a function of a duct for cooling air distribution. In the machine room 13, at a position above the intermediate wall 15 and the refrigerator compartment 17, a refrigeration unit 13 </ b> B (broken line in FIG. 2) and a cooling fan 13 </ b> C (FIG. (Dashed line) is provided. The refrigerating device 13B includes a compressor, a condenser, a cooler, and the like.

  By driving the refrigerating device 13B and the cooling fan 13C, the cool air generated in the vicinity of the cooler is blown into the intermediate wall 15 (in the duct), and the left and right refrigeration chambers 17 are passed through the ventilation holes formed in the intermediate wall 15. (See arrow W1 in FIG. 3). The cold air sent to the refrigerator compartment 17 passes through the refrigerator compartment 17 and then returns to the cooler side from an opening formed in the ceiling of the refrigerator compartment 17. Thereby, cool air is circulated and supplied to the refrigerator compartment 17. Note that a part (for example, a cooler) of the refrigerating device 13B and a cooling fan 13C may be provided inside the intermediate wall 15, for example.

  On the other hand, a heating panel 20 (see FIG. 3) is provided on a side surface of the storage compartment 18 opposite to the partition wall 30. A duct is provided on the back side of the panel 20, and a cord heater (not shown) is wired along the duct. The code heater is drawn out of a warming unit 13A (broken line in FIG. 2) arranged in the machine room 13, and the warming unit 13A is provided with a heating fan. When the warming unit 13A is driven, the inside of the duct is warmed by Joule heat generated from the code heater. In addition, by driving the heating fan at the same time as the storage unit 13A, warm air is blown into the storage room 18 from the ventilation holes formed in the panel 20 (see the arrow W2 in FIG. 3). Thus, the inside of the storage room 18 is heated by the radiant heat from the panel 20 and the warm air blown out from the vent.

  Next, the configuration of the partition wall 30 will be described in detail. In the following description, the partition wall 30 provided in the left storage room 16 will be described as an example. As shown in FIGS. 2 and 5, the partition wall 30 is configured by stacking a plurality of unit partition walls 31 each having a long shape in the front-rear direction. As shown in FIG. 4, the unit partition wall 31 has a substantially box shape, and is attached to the intermediate wall 15 and the panel 20 via connecting members 32 provided on the side surfaces of the unit partition wall 31, respectively. (See FIG. 3). The connecting member 32 is attached at one end to the unit partition wall 31 and at the other end to a support pin 34 provided on the panel 20 (or the intermediate wall 15). The connecting member 32 is attached to another member (the unit partition wall 31 or the support pin 34) by, for example, screwing, but the attaching structure is not limited to this.

  Two vertically adjacent unit partition walls 31, 31 (two vertically arranged wall portions) are arranged with a slight gap therebetween, and the tray 25 is moved between the refrigerator compartment 17 and the warming compartment 18 through the gap. It is distributed over both sides. In the present embodiment, as shown in FIG. 5, two trays 25 are arranged in the storage room 16 along the front-back direction (the direction in which the partition wall 30 extends and the horizontal direction). The tray 25 is supported by the unit partition wall 31.

  As shown in FIG. 5, a contact member 41 is provided on the lower surface of the unit partition wall 31. The contact member 41 is accommodated inside the unit partition wall 31, and the lower end of the contact member 41 projects downward through an opening formed on the lower surface of the unit partition wall 31. The contact member 41 has a long shape in the front-rear direction, and is attached to the unit partition wall 31 so as to be vertically movable. The contact members 41 are provided corresponding to the trays 25, respectively, as shown in FIG. The contact member 41 is urged downward by an elastic member (for example, a leaf spring or the like) built in the unit partition wall 31. Thereby, as shown in FIG. 5, the contact member 41 is in contact with the upper surface of the tray 25, so that the gap between the two unit partition walls 31, 31 can be closed. The contact member 41 may be configured to be urged downward by its own weight.

  A stopper member 50 is provided on the upper surface of the unit partition wall 31 at the center in the front-rear direction. As shown in FIG. 5, the stopper member 50 is provided with its upper end protruding upward from the unit partition wall 31, and the upper surface of the stopper member 50 has a stepped shape following the outer peripheral end of the tray 25. I have. As a result, the stopper member 50 is disposed between the two trays 25, 25, as shown in FIG. 5, to position the respective trays 25 in the front-rear direction and to form the two unit partition walls 31, 31. The gap S1 between them is closed. The stopper member 50 is attached to the unit partition wall 31 so as to be able to move up and down, and is urged upward by an elastic member built in the unit partition wall 31. Thus, when the tray 25 is slid in the front-rear direction, the stopper member 50 can be pushed down by the tray 25.

  Shutters 60 are provided at both ends in the front-rear direction on the upper surface of the unit partition wall 31, respectively. The shutter 60 is disposed outside the tray 25 in the front-rear direction, so that the tray 25 is prevented from falling out of the gap S1 and closes the gap S1 between the two unit partition walls 31, 31. The shutter 60 is rotatably attached to the unit partition wall 31 (the lower wall portion of the two wall portions), and puts the tray 25 in and out between the unit partition walls 31. At this time, the shutter 60 can be pushed down by the tray 25.

  Next, the mounting structure of the shutter 60 to the unit partition wall 31 will be specifically described. The unit partition wall 31 of the present embodiment has a hollow shape. FIG. 6 is a diagram illustrating an internal structure of the unit partition wall 31. As shown in FIG. 4, the unit partition wall 31 includes a main body 31 </ b> A that mainly configures the side surface, the upper surface, and the lower surface, and a cover portion 31 </ b> B that configures each longitudinal end surface (front or rear surface). Have. In FIG. 6, the upper unit partition wall 31 is not shown.

  As shown in FIG. 6, the shutter 60 is rotatably attached to a shaft 43 provided on the inner surface of the main body 31A. The shutter 60 is rotatably attached to the shaft 43, extends from the shaft 43 toward the cover 31 </ b> B (front), and has a first protrusion that protrudes downward from the tip of the extension 61. A portion 62 and a second protruding portion 63 that protrudes upward from the distal end of the extending portion 61 to close a part of the gap S1. Accordingly, the shutter 60 is configured such that the second protruding portion 63 closes a part of the gap S1 (the position shown in FIG. 6) and the second protruding portion 63 (at least a part of the shutter) is located inside the unit partition wall 31. And can be displaced between an open position (a position shown in FIG. 7) that opens a part of the gap S1. The extension 61 and the first protrusion 62 are accommodated inside the unit partition wall 31.

  A leaf spring 45 is provided inside the unit partition wall 31. The leaf spring 45 is fixed to the unit partition wall 31 at one end in the longitudinal direction, and is in contact with the lower part of the extension 61 at the other end. The second projecting portion 63 has a first inclined surface 63A inclined downward toward the outside of the storage room 16 (left side in FIG. 6) and a second inclined surface inclined downward toward the inside of the storage room 16 (right side in FIG. 6). Surface 63B.

  When the operator inserts the tray 25 into the gap S1, as shown in FIG. 6, the end surface 25A of the tray 25 contacts the first inclined surface 63A. When the tray 25 is further pushed in from this state, the tray 25 presses the first inclined surface 63 </ b> A, thereby bending the leaf spring 45 and rotating the shutter 60 counterclockwise about the shaft 43. . As a result, as shown in FIG. 7, the second protruding portion 63 is displaced below the upper surface of the unit partition wall 31 to be in an open position for opening the gap S1, so that the tray 25 is inserted into the gap S1. Becomes possible. A notch 31D that opens upward is formed in the cover 31B, and a part of the second protrusion 63 is exposed to the outside of the unit partition wall 31 through the notch 31D at the open position. ing.

  Then, as shown by the two-dot chain line in FIG. 6, when the tray 25 completely passes over the second protrusion 63, the pressing of the second protrusion 63 by the tray 25 is released, and the leaf spring 45 elastically returns. As a result, the extended portion 61 is pressed from below by the leaf spring 45, and the shutter 60 returns to the closed position. When the tray 25 is taken out of the gap S1, the shutter 60 can be rotated counterclockwise by pressing the second inclined surface 63B of the second protruding portion 63 with the end surface of the tray 25.

  Further, on the inner surface of the unit partition wall 31, a rib 46 having an elongated shape in the front-rear direction (the left-right direction in FIG. 7) is formed. In the open position, the rib 46 (rotation restricting portion) is arranged below the protruding end of the first protruding portion 62 (the lower end of the shutter 60) with a slight gap. Thus, when the shutter 60 rotates counterclockwise beyond the open position, the further rotation is restricted by the first protrusion 62 abutting on the rib 46. When the first protrusion 62 is in contact with the rib 46, the lower surface of the second protrusion 63 and the bottom surface of the notch 31D are arranged at an interval. That is, the first projecting portion 62 and the rib 46 have a function of preventing the second projecting portion 63 from contacting the cover portion 31B. In the open position, the first protrusion 62 may be in contact with the rib 46.

  Further, as shown in FIGS. 4 and 7, a plurality of protrusions 26 are formed on the peripheral end of the tray 25. The protrusions 26 are arranged over the entire circumference of the tray 25. As a result, when the two trays 25 are overlapped with each other, the projection 26 of the upper tray 25 comes into contact with the peripheral end of the lower tray 25 from above. Can be suppressed from adhering over the entire surface. Therefore, the stacked trays 25 can be easily separated from each other. Further, of the plurality of protrusions 26, two protrusions (labeled 26A) provided on the peripheral end portion 25B of the tray 25 on the shutter 60 side move the shutter 60 in the left-right direction (X-axis direction in FIG. 3). It is arranged so as to sandwich it from both sides. The distance X1 between the shutter 60 (more specifically, the second protrusion 63) and the protrusion 26A in the X-axis direction is, for example, the distance between the tray 25 and the panel 20 (or the intermediate wall 15) in the X-axis direction. It is set to a value smaller than X2.

  Next, effects of the present embodiment will be described. In the present embodiment, when the tray 25 is displaced in the arrangement direction (left-right direction) of the pair of protrusions 26A, 26A, one of the protrusions 26A comes into contact with the shutter 60, and further displacement is restricted. You. Thereby, the positioning of the tray 25 in the left-right direction can be performed. Further, since the shutter 60 can be used as a positioning member for the tray 25, there is no need to provide a dedicated positioning member, and a simpler configuration can be achieved.

  In the X-axis direction, the distance X1 between the shutter 60 (more specifically, the second protrusion 63) and the protrusion 26A is greater than the distance X2 between the tray 25 and the panel 20 (or the intermediate wall 15) in the X-axis direction. Is also set at a small value. Thus, when the tray 25 is displaced in the X-axis direction, one of the protrusions 26 </ b> A abuts on the shutter 60, thereby suppressing the situation where the tray 25 abuts on the panel 20 (or the intermediate wall 15). be able to. When the tray 25 and the inner wall (the panel 20 or the intermediate wall 15) of the storage room 16 come into contact with each other, air cannot pass between the tray 25 and the inner wall of the storage room 16, and the air inside the storage room 16 cannot be passed. There is a concern that the flow of data may worsen, but in the present embodiment, such a situation can be suppressed. Further, when the tray 25 contacts the panel 20, the heat of the panel 20 is conducted to the tray 25, and there is a concern that the tray 25 may be deteriorated by the heat, but such a situation can be suppressed.

  Further, in the present embodiment, the lower end (first protruding portion 62) of the shutter 60 abuts on the rib 46, whereby the rotation thereof can be restricted. Since the rib 46 is provided inside the unit partition wall 31, it is not visible from the outside, and the design can be further enhanced. Further, since the rotation of the shutter 60 is regulated by the rib 46, it is possible to prevent the second protrusion 63 of the shutter 60 from abutting on the cover 31B. If the shutter 60 and the cover portion 31B are configured to be in contact with each other, there is a concern that the cover portion 31B, which is a design component, may be damaged due to friction and the design quality may deteriorate. In the present embodiment, such a situation can be suppressed.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. In the hot / cold serving car of the present embodiment, the configuration of the shutter is different from that of the above-described embodiment. The same parts as those in the above-described embodiment are denoted by the same reference numerals, and redundant description will be omitted. As shown in FIG. 8, the shutter 160 of the present embodiment is rotatably attached to a shaft 143 provided inside the unit partition 31, and the end of the unit partition 31 from the shaft 143. An extension 161 extending to the side where the tray 25 is inserted (left side in FIG. 8), and a projection 163 projecting upward from the tip of the extension 161 to close a part of the gap S1 are provided. I have.

  In addition, a support portion 147 that supports the extension portion 161 is provided below the extension portion 161 inside the unit partition wall 31. Inside the unit partition wall 31, a coil spring 145 is provided at a position inside the unit partition wall 31 with respect to the support portion 147 so as to extend vertically. When the operator inserts the tray 25 into the gap S1, as shown in FIG. 8, the end surface 25A of the tray 25 comes into contact with the protrusion 163 from the left side in FIG. When the tray 25 is further pushed in from this state, the tray 25 presses the protruding portion 163, so that the shutter 160 rotates clockwise about the shaft portion 143.

  As a result, as shown in FIG. 9, the protruding portion 163 is displaced below the upper surface of the unit partition wall 31 to be in an open position for opening the gap S1, so that the tray 25 can be inserted into the gap S1. Becomes In the process where the shutter 160 rotates clockwise around the shaft 143, the protrusion 163 contacts the upper part of the coil spring 145, and thereafter, the coil spring 145 is compressed. In the open position shown in FIG. 9, the lower surface of the tray 25 is in contact with the extension 161. Then, as shown by the two-dot chain line in FIG. 8, when the tray 25 completely passes over the projecting portion 163, the pressing of the extension portion 161 by the tray 25 is released, and the coil spring 145 elastically returns. As a result, the shutter 160 rotates counterclockwise about the shaft 143. The shutter 160 rotates until the extension 161 contacts the support 147, and as a result, returns to the closed position shown in FIG.

  As described above, in the present embodiment, in the process of inserting the tray 25 into the gap S1 between the unit partition walls 31, 31 arranged vertically, the shutter 160 is pressed by the tray 25 and rotated clockwise, whereby the shutter is rotated. 160 can be displaced to the open position. By doing so, the rotation direction of the shutter 160 can be made the same as the insertion direction of the tray 25, and the rotation of the shutter 160 can be performed more easily. In the initial stage of the rotation of the shutter 160, the shutter 160 does not come into contact with the coil spring 145. Therefore, it is possible to suppress a situation in which the insertion of the tray 25 is hindered due to the repulsive force of the coil spring 145.

<Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIGS. In the hot / cold serving car of the present embodiment, the configuration of the shutter is different from that of the above embodiment. The same parts as those in the above-described embodiment are denoted by the same reference numerals, and redundant description will be omitted. As shown in FIG. 10, the shutter 260 of this embodiment is provided inside the unit partition wall 31 and is attached to the unit partition wall 31 so as to be vertically movable. The shutter 260 includes an extending portion 261 extending in the vertical direction, and a projecting portion 263 projecting upward from an upper end of the extending portion 261 to close a part of the gap S1. A coil spring 245 is arranged below the extension 261 so as to extend vertically. The protruding portion 263 has a first inclined surface 263A inclined downward toward the outside of the storage room 16 (left side in FIG. 10) and a second inclined surface inclined downward toward the inside of the storage room 16 (right side in FIG. 10). 263B.

  When the operator inserts the tray 25 into the gap S1, the end surface 25A of the tray 25 comes into contact with the first inclined surface 263A of the protrusion 263 as shown in FIG. When the tray 25 is further pushed in from this state, the tray 260 presses the first inclined surface 263A, thereby compressing the coil spring 245 and lowering the shutter 260. As a result, as shown by the two-dot chain line in FIG. 10, the protruding portion 263 is displaced below the upper surface of the unit partition wall 31 to be in an open position for opening the gap S1, and the tray 25 is inserted into the gap S1. It becomes possible. When the tray 25 completely passes over the protruding portion 263, the coil spring 245 elastically returns, and the shutter 260 returns to the closed position. When taking out the tray 25 from the gap S1, the shutter 260 can be lowered by pressing the second inclined surface 263B of the protruding portion 263 with the end surface of the tray 25.

  Next, effects of the present embodiment will be described with reference to comparative examples in FIGS. 11 and 12 show a configuration in which the shutter 60 is rotated counterclockwise when the tray 25 is inserted. In this configuration, the first spring 62 of the shutter 60 presses and compresses the coil spring 250. Thereby, the shutter 60 can be returned to the closed position by the repulsive force of the coil spring 250. With such a configuration, when the tray 25 is inserted into the gap S1, the repulsive force of the coil spring 250 acts in a direction opposite to the insertion direction of the tray 25, and the force required for inserting the tray 25 increases. When the shutter 260 is configured to move up and down as in the present embodiment, the situation in which the repulsive force of the coil spring 245 acts in the horizontal direction can be reduced as compared with the configuration in which the shutter 260 is rotated. Thus, the force required for inserting the tray 25 can be further reduced, and workability can be improved. Note that the technical scope of the present invention includes the configurations in FIGS. 11 and 12.

<Embodiment 4>
Next, a fourth embodiment of the present invention will be described with reference to FIGS. In the hot / cold serving car of the present embodiment, the configuration related to the rotation of the shutter is different from the above embodiment. The same parts as those in the above-described embodiment are denoted by the same reference numerals, and redundant description will be omitted. As shown in FIG. 13, the shutter 360 of the present embodiment includes an extending portion 61, a first projecting portion 62, and a second projecting portion 63, similarly to the first embodiment, and At the time of insertion, the shutter 360 is turned counterclockwise. The shutter 360 according to the present embodiment includes an extending portion 361 that extends obliquely downward from an end of the extending portion 61 on the shaft portion 43 side, and a weight portion 365 provided at a tip of the extending portion 361. .

  By providing such a weight portion 365, a clockwise rotational moment about the shaft portion 43 acts on the shutter 360. Due to this, the shutter 360 is biased to rotate clockwise as a whole. Further, the shutter 360 urged clockwise has a configuration in which clockwise rotation is regulated, for example, by the extended portion 61 abutting against the upper wall 31E of the unit partition wall 31 from below. Has become. The clockwise rotational moment acting on the shutter 360 can be adjusted by appropriately setting the length of the extending portion 361 and the weight of the weight portion 365.

  In the present embodiment, by providing the weight portion 365, the shutter 360 is urged to rotate clockwise (toward the closing position) as a whole. For this reason, the shutter 360 at the open position (see FIG. 14) can be returned to the closed position without providing an urging means such as a leaf spring or a coil spring, and the number of components can be reduced. In the shutter 360, when the extending portion 61, the first projecting portion 62, the second projecting portion 63, and the like are made of, for example, a synthetic resin, the weight portion 365 is made of, for example, a material having a larger specific gravity than the synthetic resin. (A metal or the like). In such a case, the shutter 360 can be formed as one component by integrally molding the weight portion 365 and other components by insert molding or the like.
