JP, 2014-54522, A

  It is known that the partition wall is provided with a tray stopper for positioning the tray. When such a tray stopper is pressed against the tray, the tray stopper is configured to retract inside the partition wall so as not to prevent the tray from being taken in and out. However, in order to retract the tray stopper, the operator needs to press the tray stopper via the tray. Therefore, in order to improve workability, a structure is required that can move the tray stopper with a smaller force.

  The present invention was completed in view of the above circumstances, and an object thereof is to provide a cold storage device capable of moving a tray stopper with a smaller force.

  In order to solve the above-mentioned problems, the refrigerating / heating apparatus of the present invention is provided with a heat-insulating box having a storage chamber capable of accommodating a tray, and a partition provided in the storage chamber for partitioning the storage chamber into a refrigerating chamber and a warming chamber. A wall, the partition wall is arranged in the vertical direction, and at least two wall portions extending along the extending direction of the partition wall are provided, and the tray is provided between the two wall portions. It is configured to be arranged across both the refrigerating chamber and the warming chamber through the formed gap, and the gap has a longitudinal shape extending along the extending direction of the two wall portions, One of the two wall portions is provided with a tray stopper that closes a part of the gap and positions the tray, and the tray stoppers are arranged along the longitudinal direction of the gap. It has a pair of shaft portions, and is rotated by the tray from one side in the longitudinal direction to rotate the first shaft portion arranged on one side in the longitudinal direction of the pair of shaft portions. As a result of the rotation about the center, it is configured to open the part of the gap and is arranged on the other side of the pair of shaft portions by being pressed by the tray from the other side in the longitudinal direction. As a result of the rotation about the second shaft portion as the rotation center, the part of the gap is opened.

  According to the above configuration, by rotating the tray stopper, a part of the gap can be opened, and the tray can be slid along the longitudinal direction of the gap. When the tray stopper is rotated, the force from the tray can be more efficiently applied to the tray stopper, as compared with the structure in which the tray stopper is moved in the vertical direction. As a result, the tray stopper can be moved with a smaller force. Further, the two shaft portions that are the rotation centers of the tray stoppers are arranged along the longitudinal direction of the gap, and when the tray stopper is pressed from one side, the first shaft portion is arranged on one side. Is the center of rotation, and when pressed from the other side, the second shaft portion arranged on the other side becomes the center of rotation. As a result, the tray stopper can be rotated regardless of which direction the tray stopper is pressed against the tray in the longitudinal direction of the gap.

  In addition, the one wall portion has a box shape having a first wall portion that forms the gap, and the tray stopper has a longitudinal shape that extends along a longitudinal direction of the gap, and the first wall portion has the first wall portion. By rotating the shaft portion or the second shaft portion as a rotation center, the shaft portion or the second shaft portion is housed inside the one wall portion through a through hole formed in the first wall portion. The portion is arranged on the back side of the first wall portion, and inside the pair of shaft portions, a pair of linear guide portions extending from the back surface of the first wall portion toward the back side is arranged. The pair of guide portions may be arranged so as to face each other with a gap in the longitudinal direction, and the facing gap may become smaller toward the back side.

  By providing the pair of guide portions, the positions of the first shaft portion and the second shaft portion can be regulated. Here, the pair of guide portions are configured such that the facing interval becomes smaller toward the back side. Therefore, the tray stopper can be rotated while being moved to the back side. When the longitudinal tray stopper extending in the longitudinal direction of the gap is rotated, the longer the tray stopper is, the closer the longitudinal direction of the tray stopper is to the vertical direction. As a result, in order to accommodate the tray stopper that is long in the vertical direction, it is necessary to increase the thickness of one wall portion. In the above configuration, since the tray stopper is moved to the back side, the amount of rotation of the tray stopper can be reduced and the gap can be opened, and the situation in which the longitudinal direction of the tray stopper approaches the vertical direction can be suppressed. The thickness of the wall portion of can be made smaller.

  In addition, the one wall portion has a box shape having a first wall portion that forms the gap, and the tray stopper rotates about the first shaft portion or the second shaft portion as a rotation center. By doing so, it is configured to be housed inside the one wall portion through a through hole formed in the first wall portion, and the first shaft portion is rotatable on the back surface of the first wall portion. A first holding portion for holding and a second holding portion for rotatably holding the second shaft portion are respectively provided, and the first holding portion has a concave shape opened to the one side in the longitudinal direction. The second holding portion has a concave shape opened to the other side in the longitudinal direction, and when the tray stopper rotates about the first shaft portion, the second shaft A part is separated from the second holding part, and the first shaft part is separated from the first holding part when the tray stopper rotates about the second shaft part. can do.

  With such a configuration, the first shaft portion and the second shaft portion can be reliably held, and the tray stopper can be rotated more reliably. Here, when the tray stopper rotates about one shaft portion (first shaft portion or second shaft portion), the holding of the other shaft portion is released. Therefore, the rotation of the tray stopper is not hindered.

  A curved second guide portion for the second shaft portion is arranged inside the pair of shaft portions and extends along a rotation locus of the second shaft portion around the first shaft portion. Can be something. With this configuration, when the second shaft portion rotates about the first shaft portion, the second shaft portion guide portion can guide the second shaft portion.

  Further, a curved second guide portion for the second shaft portion is arranged outside the pair of shaft portions and extends along a rotation trajectory of the second shaft portion around the first shaft portion. Can be something. With such a configuration, when the second shaft portion rotates around the first shaft portion, the second shaft portion can be guided by the second shaft portion guide portion.

  According to the present invention, there is provided a refrigerating / heating apparatus capable of moving the tray stopper with a smaller force.

<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 12. In the present embodiment, the cold / hot storage device 10 is exemplified as the cold / hot storage device. As shown in FIG. 1 and FIG. 2, the hot and cold serving vehicle 10 includes a heat insulating box 11 having a storage chamber 16, casters 12 attached to the bottom surface of the heat insulating box 11, and a machine room arranged above the heat insulating box 11. 13 and. The heat insulating box 11 is composed of a wall portion filled with a heat insulating material such as urethane foam, and has an overall rectangular parallelepiped shape in which both front and rear sides are open.

  As shown in FIG. 2, in the inner space of the heat insulating box 11, the vertical frames 14 are provided at both sides in the front-rear direction (Y-axis direction) at the center in the width direction (left-right direction in FIG. 2, X-axis direction). It is standing. An intermediate wall 15 (see FIG. 3) is provided between the pair of vertical frames 14, 14. The inner space of the heat insulation box 11 is divided into left and right by the intermediate wall 15 to form two storage chambers 16 capable of accommodating the tray 25. In FIG. 2, only the left storage chamber 16 is shown. A partition wall 30 (described later in detail) that extends in the front-rear direction is provided in each storage chamber 16. As a result, the storage chamber 16 is partitioned by the partition wall 30 into a refrigerating chamber 17 and a warming chamber 18.

  In the present embodiment, the two storage chambers 16, 16 are arranged symmetrically with respect to the intermediate wall 15. That is, in the left-side storage chamber 16 shown in FIG. 2, the heating chamber 18 is arranged on the left side and the refrigerating chamber 17 is arranged on the right side. On the other hand, in the storage room 16 on the right side not shown in FIG. 2, the refrigerating room 17 is arranged on the left side and the warming room 18 is arranged on the right side. Further, the heat insulating box 11 is provided with double doors 19 in a shape corresponding to the front-rear direction of each storage chamber 16. Each of the refrigerating chambers 17 and 17 and each of the warming chambers 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 thereof. Thereby, the intermediate wall 15 has a function of a duct for circulating cold air. Inside the machine room 13, a refrigeration apparatus 13B (broken line in FIG. 2) and a cooling fan 13C (FIG. 2) for blowing the cold air generated by the refrigeration apparatus 13B (see FIG. 2) are located above the intermediate wall 15 and the refrigeration room 17. (Dashed line) is installed. The refrigeration system 13B is composed of a compressor, a condenser, a cooler, and the like.

  By driving the refrigerating device 13B and the cooling fan 13C, the cool air generated near the cooler is blown into the intermediate wall 15 (in the duct), and the left and right refrigerating chambers 17 are passed through the ventilation holes formed in the intermediate wall 15. (See arrow W1 in FIG. 3). The cool air sent to the refrigerating compartment 17 passes through the refrigerating compartment 17 and then returns to the cooler side from the opening formed in the ceiling of the refrigerating compartment 17. As a result, cold air is circulated and supplied to the refrigerating chamber 17. A part of the refrigerating apparatus 13B (for example, a cooler) or 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 stretched on the side surface of the heating chamber 18 opposite to the partition wall 30. A duct is provided on the back side of the panel 20, and a code heater (not shown) is wired along the duct. The cord heater is drawn out from a heating unit 13A (broken line in FIG. 2) arranged in the machine room 13, and the heating unit 13A is provided with a heating fan. When the heating unit 13A is driven, the inside of the duct is warmed by the Joule heat generated from the cord heater. Further, by driving the heating fan at the same time as the heating unit 13A, warm air is blown into the heating chamber 18 from the ventilation hole formed in the panel 20 (see arrow W2 in FIG. 3). In this way, the inside of the heating chamber 18 is heated by the radiant heat from the panel 20 and the warm air blown out from the ventilation port.

  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 chamber 16 will be described as an example. As shown in FIGS. 2 and 4, the partition wall 30 is formed by stacking a plurality of unit partition walls 31 each having a long shape that is long in the front-rear direction. As shown in FIGS. 4 and 5, the unit partition wall 31 has a box shape, and is connected to the intermediate wall 15 and the panel 20 via connecting members 32 and 32 provided on the side surfaces of the unit partition wall 31, respectively. Each is attached (see Figure 3). The connecting member 32 is attached to the unit partition wall 31 at one end and is attached to the support pin 34 provided on the panel 20 (or the intermediate wall 15) at the other end. The connecting member 32 is attached to another member (the unit partition wall 31 or the support pin 34) by, for example, a screw or a bolt, but the attaching structure is not limited to this.

  Further, as shown in FIGS. 4 and 5, a tray stopper 50 and two shutters 60, 60 are provided on the upper portion of the unit partition wall 31, and two contact members 41 are provided on the lower portion of the unit partition wall 31. , 41 are provided. The tray stopper 50 and the two shutters 60, 60 are not provided on the uppermost unit partition wall 31. A gap S1 is formed between each of the plurality of unit partition walls 31. The gap S1 referred to here is a space formed between two unit partition walls 31, 31 that are vertically adjacent to each other.

  The gap S1 extends along the longitudinal direction (front-back direction) of the unit partition wall 31, and the tray 25 is arranged over both the refrigerating chamber 17 and the warming chamber 18 through the gap S1. In the present embodiment, as shown in FIG. 3, two trays 25, 25 are arranged in the storage chamber 16 along the front-rear direction (the extending direction of the partition wall 30 and the horizontal direction). The gap S1 is closed by movable members such as the contact member 41, the tray stopper 50, and the shutter 60. This prevents the situation where air flows between the refrigerating chamber 17 and the warming chamber 18 through the gap S1. When the tray 25 is inserted into the gap S1, the shutter 60 and the contact member 41 move so that the tray 25 can be inserted. The tray 25 inserted into the gap S1 is supported by the upper surface of the unit partition wall 31. The contact member 41 contacts the tray 25 from above.

  Here, among the plurality of unit partition walls 31, the two unit partition walls 31, 31 that are vertically adjacent to each other are examples of the "two wall portions" described in the claims. The gap S1 is an example of the "gap formed between the two wall portions" described in the claims. It should be noted that the gap S1 is, specifically, of the two unit partition walls 31, 31 that are vertically adjacent to each other, the tray stopper 50 and the two shutters 60, 60 of the unit partition wall 31, which is arranged on the lower side, It is closed by the two contact members 41, 41 of the unit partition wall 31 arranged on the upper side (see FIG. 5).

  As shown in FIG. 5, a contact member 41 is provided on the lower surface of the unit partition wall 31. Most of the contact member 41 is housed inside the unit partition wall 31, and the lower end of the contact member 41 projects downward through an opening formed in the lower surface of the unit partition wall 31. ing. 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 a leaf spring 42 (see FIG. 5) built in the unit partition wall 31. As a result, as shown in FIG. 5, the contact member 41 contacts the upper surface of the tray 25, and the gap S1 between the two unit partition walls 31 can be closed. The contact member 41 may be biased downward by its own weight.

  A tray stopper 50 (positioning member) 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 tray stopper 50 is provided such that the upper end portion thereof projects upward from the unit partition wall 31, and the surface shape of the tray stopper 50 has a step shape that follows the outer peripheral end portion of the tray 25. ing. As shown in FIG. 4, the tray stopper 50 has a function as a member (positioning member) for positioning each tray 25 in the front-rear direction by being arranged between the two trays 25, 25, and also has two functions. It has a function as a member (shutter) that closes a part of the gap S1 between the unit partition walls 31, 31. The tray stopper 50 is rotatably attached to the unit partition wall 31 (details will be described later).

  As shown in FIG. 4, on the upper surface of the unit partition wall 31, shutters 60 are provided at both ends in the front-rear direction. The shutter 60 is arranged outside the tray 25 in the front-rear direction to prevent the tray 25 from coming out of the gap S1 and close the gap S1 between the two unit partition walls 31, 31. The shutter 60 is rotatably attached to the unit partition wall 31 (the wall portion arranged on the lower side of the two wall portions), and the tray 25 is inserted and removed between the unit partition walls 31 and 31. At this time, the shutter 25 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 this embodiment has a hollow shape. 5 to 7 are views showing the internal structure of the unit partition wall 31. As shown in FIG. 5, the unit partition wall 31 includes a main body portion 31A that mainly forms side surfaces, an upper surface, and a lower surface, and a cover portion 31B that forms each end surface (front surface or rear surface) in the longitudinal direction. I have it. Note that the main body 31A is configured by combining a pair of half-split bodies, and in FIGS. 5 and 6, only one half-split half is shown.

  As shown in FIG. 7, the shutter 60 is rotatably attached to the shaft portion 43 provided on the inner surface of the main body portion 31A. The shutter 60 is rotatably attached to the shaft portion 43 and extends from the shaft portion 43 to the cover portion 31B side (front side in FIG. 7). The first protrusion 62 and the second protrusion 63 that protrudes upward from the tip of the extension 61 to close a part of the gap S1 are provided. As a result, the shutter 60 has a closed position (the position shown in FIG. 7) in which the second protrusion 63 closes a part of the gap S1 and the second protrusion 63 is accommodated inside the unit partition wall 31 to form a gap. It is displaceable between an open position where a part of S1 is opened.

  A leaf spring 45 is provided inside the unit partition wall 31. As shown in FIG. 6, the leaf spring 45 has an elongated shape extending from the shutter 60 to the tray stopper 50, and the leaf spring 45 has a plurality of columnar mountings provided in the main body 31A. It is fixed to the portion 35. The end portion of the leaf spring 45 on the shutter 60 side is in contact with the lower portion of the extending portion 61, and can be flexibly deformed with the mounting portion 35 arranged on the shutter 60 side as a fulcrum. On the other hand, the end portion of the leaf spring 45 on the tray stopper 50 side is in contact with the tray stopper 50 from below, and can be flexibly deformed with the mounting portion 35 arranged on the tray stopper 50 side as a fulcrum. There is.

  The second protruding portion 63 of the shutter 60 has a first inclined surface 63A that descends and slopes toward the outside of the storage chamber 16 (left side of FIG. 6) and a descending slope that slopes toward the inside of the storage chamber 16 (right side of FIG. 6). And a second inclined surface 63B. When the operator inserts the tray 25 into the gap S1, the end surface 25A of the tray 25 contacts the first inclined surface 63A, as shown in FIG. When the tray 25 is further pushed in from this state, the tray 25 presses the first inclined surface 63A, thereby bending the leaf spring 45 and rotating the shutter 60 counterclockwise about the shaft portion 43. .. As a result, the tray 25 can be inserted into the gap S1.

  Then, as shown by the chain double-dashed line in FIG. 7, when the tray 25 completely passes over the second protruding portion 63, the pressing of the second protruding portion 63 by the tray 25 is released, and the leaf spring 45 elastically returns. As a result, the leaf spring 45 presses the extending portion 61 from below, so that the shutter 60 returns to the closed position. The cover portion 31B is formed with a cutout portion 31D that opens upward, and the second protrusion 63 and the cover portion 31B rotate without interference. As shown in FIGS. 3 and 7, the first projecting portion 62 is arranged so as to overlap the cutout portion 31D in a front view. As a result, it is possible to suppress the situation where the inside of the unit partition wall 31 is visually observed in the front view. Further, when the tray 25 is taken out from the gap S1, the shutter 60 can be rotated counterclockwise by pressing the second inclined surface 63B of the second protrusion 63 by the end surface of the tray 25.

  Next, the configuration related to the rotation of the tray stopper 50 will be described. The tray stopper 50 is provided below the stopper main body 53 and a stopper main body 53 protruding upward through a through hole 36 </ b> A formed in the upper wall 36 (first wall forming the gap) of the unit partition wall 31. And a pair of shaft portions 51 and 52 that are provided. As shown in FIGS. 6 and 8, the stopper main body portion 53 has a step shape in which both side surfaces in the Y-axis direction follow the shape of the peripheral end portion of the tray 25. The stopper main body 53 has an inclined surface 53A that inclines so as to approach the tray 25 side as it goes downward, and the tray stopper 50 rotates when the inclined surface 53A is pressed by the tray 25. (See below for details). Further, the stopper main body portion 53 has, for example, a long shape extending along the longitudinal direction of the gap S1. In other words, the stopper main body 53 has a longitudinal shape whose length in the front-rear direction (Y-axis direction) is larger than the length in the vertical direction (Z-axis direction).

  The shaft portion 51 and the shaft portion 52 have, for example, a cylindrical shape that is long in the X-axis direction, and are arranged on the back side of the upper wall portion 36 (inside the unit partition wall 31). The shaft portion 51 (first shaft portion) is provided at one end portion of the stopper body portion 53 in the Y-axis direction, and the shaft portion 52 (second shaft portion) is the other end of the stopper body portion 53 in the Y-axis direction. Is provided in the section. In addition, a pair of guide portions 56 and 57 are provided inside the unit partition wall 31. The guide portions 56 and 57 are formed on the inner surface of the main body portion 31A and each have a linear shape (rib shape) extending from the back surface of the upper wall portion 36 toward the back side (lower side).

  The pair of guide portions 56 and 57 are arranged inside the pair of shaft portions 51 and 52 (between the pair of shaft portions 51 and 52 in the Y-axis direction), and are inclined so as to be directed inward as they go downward. To be done. In other words, the pair of guide portions 56 and 57 are arranged so as to face each other with a space in the Y-axis direction, and the facing distance Y1 becomes smaller toward the back side. Further, on the inner surface of the main body portion 31A, a restriction rib 58 extending in the Y-axis direction is provided below the shaft portion 51, and a restriction rib 58 extending in the Y-axis direction is provided below the shaft portion 52. 59 is provided. The regulating ribs 58 and 59 are arranged at the same height as the lower ends of the guide portions 56 and 57, respectively.

  Next, the operation of the tray stopper 50 will be described with reference to FIGS. 8 to 11, the unit partition wall 31 arranged on the upper side of the two unit partition walls 31, 31 that are vertically adjacent to each other is not shown. Here, an operation of the tray stopper 50 when the tray 25 arranged on the front side of the tray stopper 50 is slid to the rear side of the tray stopper 50 will be exemplified. When the operator slides the tray 25 to the rear side (right side in FIG. 8), the inclined surface 53A of the tray stopper 50 is pressed by the tray stopper 50 from the front side. As a result, the tray stopper 50 is displaced rearward, and when the shaft portion 51 comes into contact with the guide portion 56, thereafter, the tray stopper 50 rotates clockwise around the shaft portion 51. As a result, the stopper body 53 enters the inside of the unit partition wall 31 through the through hole 36A. When the tray stopper 50 rotates to bring the shaft portion 52 into contact with the regulation rib 59 from above (see FIG. 9), the tray stopper 50 is rotated counterclockwise with the shaft portion 52 as the rotation center. Rotate.

  As a result, as shown in FIG. 10, the entire stopper main body 53 is housed inside the unit partition wall 31, and a part of the gap S1 (the portion closed by the stopper main body 53) is opened. Then, the tray 25 can be slid to the rear side. Further, when the shaft portions 51 and 52 are displaced downward during the process of rotating the tray stopper 50, one end portions of the leaf springs 45 and 45 are pressed by the shaft portions 51 and 52, respectively, and Deflection and deformation. As a result, when the tray 25 completely passes over the tray stopper 50, the pressing of the tray stopper 50 by the tray 25 is released, and the leaf springs 45, 45 elastically return. As a result, the plate springs 45, 45 press the tray stopper 50 from below, so that the tray stopper 50 returns to its original position. The leaf springs 45, 45 are not shown in FIGS. 10 and 11. Further, as shown in FIG. 8, a projecting portion 45A that projects upward is provided at the end of the leaf spring 45 on the tray stopper 50 side. When the tray stopper 50 rotates, the protrusion 45A is locked to the shaft portion (the shaft portion 51 or the shaft portion 52), so that the leaf spring 45 can be prevented from coming off the shaft portion. ..

  Further, when the tray 25 arranged on the rear side of the tray stopper 50 is slid forward, as shown in FIG. 11, the tray 25 presses the tray stopper 50 from the rear side (right side of FIG. 11). . As a result, when the shaft portion 52 comes into contact with the guide portion 57, the tray stopper 50 rotates counterclockwise around the shaft portion 52. After that, after the shaft portion 51 comes into contact with the regulation rib 58, the tray stopper 50 rotates clockwise around the shaft portion 51. As a result, the entire stopper main body 53 is housed inside the unit partition wall 31, and a part of the gap S1 (the portion closed by the stopper main body 53) is opened. As a result, the tray 25 slides to the front side. It is possible to move it. In this embodiment, the shaft portions 51 and 52 can be displaced in the Y-axis direction and the Z-axis direction within the range regulated by the guide portions 56 and 57 and the regulation ribs 58 and 59. Therefore, when the tray stopper 50 rotates about the shaft portion 51 (or the shaft portion 52) as the rotation center, the shaft portion 51 (or the shaft portion 52) itself, which is the rotation center, moves in the Y-axis direction and the Z direction. It can be displaced in the axial direction. In other words, in the present embodiment, the tray stopper 50 is housed inside the unit partition wall 31 by rotating in the Y-axis direction and the Z-axis direction while rotating around the shaft portion 51 (or the shaft portion 52). Can be operated as.

  Next, a configuration relating to the removal of the contact member 41 will be described. In the present embodiment, it is conceivable to remove the contact member 41 in order to clean the contact member 41. As described above, the two contact members 41 are arranged along the Y-axis direction, as shown in FIG. A plurality of ribs 46, 46 are provided on the inner surface of the main body portion 31A between the two contact members 41, 41. The rib 46 as described above positions the contact member 41 in the Y-axis direction. Further, on the inner surface of the main body 31A, a rib 47 extending along the Y-axis direction is provided above the rib 46. A gap S2 is provided between the rib 46 and the rib 47. A flange portion 41A is provided on the upper end of the contact member 41. This flange portion 41A prevents the contact member 41 from coming off the unit partition wall 31 downward.

  In this embodiment, by removing one of the cover portions 31B provided on the front and rear sides of the main body portion 31A, both of the two contact members 41, 41 can be removed. For example, when the front cover part 31B is removed, the contact member 41 can be removed from the front side by sliding the front contact member 41 forward. On the other hand, the rear contact member 41 can be pushed up as shown in FIG. 12 to raise the flange portion 41A to a position corresponding to the gap S2. With this configuration, the contact member 41 arranged on the rear side can be slid forward without the rib 46 and the flange portion 41A interfering with each other. As a result, the contact member 41 arranged on the rear side can also be removed from the front side. That is, in the present embodiment, the two contact members 41, 41 can be removed by removing only one of the pair of cover portions 31B, 31B. In addition, in FIG. 12, the contact member 41 in the assembled state is shown by a two-dot chain line.

  Next, the effect of this embodiment will be described. According to the present embodiment, by rotating the tray stopper 50, a part of the gap S1 can be opened, and the tray 25 can be slid along the longitudinal direction of the gap S1. When the tray stopper 50 is configured to be rotated, the force from the tray 25 can be more efficiently applied to the tray stopper 50 as compared with the configuration in which the tray stopper 50 is moved in the vertical direction. As a result, the tray stopper 50 can be moved with a smaller force. Further, two shaft portions 51 and 52, which are the center of rotation of the tray stopper 50, are arranged along the longitudinal direction of the gap S1, and when the tray stopper 50 is pressed from the front side (one side), The shaft portion 51 arranged on the front side serves as the center of rotation, and when pressed from the rear side (the other side), the shaft portion 52 arranged on the rear side serves as the center of rotation. This makes it possible to rotate the tray stopper 50 with less force regardless of which side of the longitudinal direction of the gap S1 the tray stopper 50 is pressed against the tray 25. Specifically, the force acting on the tray stopper 50 (the pressing force by the tray 25) is applied to a straight line (for example, the line L1 in FIG. 8) that connects the point of action of the force on the tray stopper 50 and the rotation center (shaft portion). For example, the direction of arrow F1 in FIG. 8 can be made closer to the vertical direction, and the rotational moment acting on the tray stopper 50 can be further increased.

  Further, in the present embodiment, the tray stopper 50 can be moved with a smaller force as compared with the configuration in which the tray stopper is moved in the vertical direction. If the tray stopper is configured to move in the vertical direction, it may be necessary to divide the tray stopper into upper and lower parts so that the tray stopper can be moved more easily. In the present embodiment, since the tray stopper can be easily moved, the tray stopper can be formed as an integral part.

  In addition, in the present embodiment, the position of the shaft portion 51 and the shaft portion 52 can be regulated by providing the pair of guide portions 56 and 57. Here, the pair of guide portions 56 and 57 are configured such that the facing distance between them becomes smaller toward the back side. Therefore, the tray stopper 50 can be rotated while being moved to the back side. When the tray stopper 50 having a long shape extending in the longitudinal direction of the gap S1 is rotated, the longer the tray stopper 50 is, the closer the longitudinal direction of the tray stopper 50 is to the vertical direction. As a result, it becomes necessary to increase the thickness of the unit partition wall 31 in order to accommodate the tray stopper 50 that is long in the vertical direction. In this embodiment, since the tray stopper 50 is moved to the back side (while being rotated), the amount of rotation of the tray stopper 50 can be reduced and the gap S1 can be opened. Since it is possible to suppress the situation of approaching to, it is possible to further reduce the thickness of the unit partition wall 31.

Next, a second embodiment of the present invention will be described with reference to FIG. The configuration related to the rotation of the tray stopper in the hot and cold serving vehicle of this embodiment is different from that of the above embodiment. The same parts as those in the above-described embodiment are designated by the same reference numerals, and duplicate description will be omitted. In the present embodiment, as shown in FIG. 13, the facing interval between the shaft portions 51 and 52 in the Y-axis direction is set to a value larger than the length of the stopper body portion 153 of the tray stopper 150. On the back side of the upper wall portion 36 of the unit partition wall 31, a holding concave portion 156 (first holding portion) that rotatably holds the shaft portion 51 and a holding concave portion 157 (first holding portion 157 that rotatably holds the shaft portion 52). 2 holding portions) are provided respectively.

  The holding recess 156 has a recessed shape that is open to the front side (one side in the Y axis direction). Specifically, the holding recess 156 includes a rear surface of the upper wall portion 36 (a lower surface of the upper wall portion 36, a rear surface of the first wall portion), a first protruding portion 156A protruding downward from the rear surface, and a first protruding portion. The second protrusion 156B is configured to protrude from the lower end of the portion 156A to the front side (shaft portion 51 side). On the other hand, the holding recess 157 has a recessed shape that is open on the rear side (the other side in the Y-axis direction). Specifically, the holding recess 157 projects from the back surface of the upper wall portion 36, the first projecting portion 157A projecting downward from the back surface, and the rear side (shaft portion 52 side) from the lower end of the first projecting portion 157A. The second projecting portion 157B is formed.

  In the Y-axis direction, the length of the through hole 36A is set larger than the length of the stopper body 153. Further, in the Y-axis direction, gaps are set between the shaft portion 51 and the first protruding portion 156A and between the shaft portion 52 and the first protruding portion 157A. As a result, the tray stopper 150 can be displaced in the Y-axis direction by the amount of the gap.

  Further, in the state where the shaft portion 51 is in contact with the first protruding portion 156A, the shaft portion 52 (denoted by reference numeral 52A, two-dot chain line in FIG. 13) is arranged rearward of the protruding end of the second protruding portion 157B. It is configured to be. That is, the shaft portion 52 is configured to be detached from the holding recess 157 when the shaft portion 51 is in contact with the first protruding portion 156A. Further, in the state where the shaft portion 52 is in contact with the first protruding portion 157A, the shaft portion 51 (denoted by reference numeral 51A, the two-dot chain line in FIG. 13) is arranged in front of the protruding end of the second protruding portion 156B. It is configured to. That is, the shaft portion 51 is configured to be detached from the holding recess 156 when the shaft portion 52 is in contact with the first protruding portion 157A. Further, an upper portion of a coil spring 145 provided in the main body portion 31A of the unit partition wall 31 is attached to a lower portion of the stopper main body portion 153.

  Next, the operation of the tray stopper 150 will be described. Here, the operation of the tray stopper 150 when sliding the tray 25 arranged on the front side of the tray stopper 150 to the rear side is illustrated. When the operator slides the tray 25 to the rear side (right side in FIG. 13), the inclined surface 153A of the tray stopper 150 is pressed by the tray stopper 150 from the front side. As a result, the tray stopper 150 is displaced rearward, so that the shaft portion 51 abuts on the first protruding portion 156A and the shaft portion 52 separates from the holding recess 157. After that, the tray stopper 150 rotates clockwise around the shaft portion 51. As a result, the stopper body 153 is housed inside the unit partition wall 31 through the through hole 36A.

  As a result, as shown by the chain double-dashed line in FIG. 13, the entire stopper main body 153 is housed inside the unit partition wall 31, and a part of the gap S1 (the portion closed by the stopper main body 153) is formed. As a result of the opening, the tray 25 can be slid to the rear side. In the process of rotating the tray stopper 150, the coil spring 145 is contracted by being pressed by the tray stopper 150. As a result, when the tray 25 completely passes over the tray stopper 150, the pressing of the tray stopper 150 by the tray 25 is released, and the coil spring 145 elastically returns. As a result, the tray stopper 150 returns to the original position (the position that closes the gap S1). Further, in the process of sliding the tray 25 arranged on the rear side of the tray stopper 150 to the front side, the shaft portion 52 abuts on the first projecting portion 157A and the shaft portion 51 separates from the holding recess 156, and thereafter. The tray stopper 150 rotates counterclockwise about the shaft 52.

  Next, the effect of this embodiment will be described. In the present embodiment, when the tray stopper 150 rotates about the shaft portion 51, the shaft portion 51 is arranged in the holding recess 156. As a result, the shaft portion 51 is restricted from moving downward and rearward. As a result, the shaft portion 51 can be reliably held, and the tray stopper 150 can be more reliably rotated. Further, when the tray stopper 150 rotates about the shaft 52, the shaft 52 can be held by the holding recess 157. Further, when the tray stopper 150 rotates about one shaft portion (the shaft portion 51 or the shaft portion 52), the holding of the other shaft portion is released. Therefore, the rotation of the tray stopper 150 is not hindered.
