Next, with reference to FIG. 3 thru | or FIG. 10, the mounting shelf 10 and the partition member 20 of the layout vehicle 1 are demonstrated in detail.
FIG. 3 is a perspective view showing the structure of the mounting shelf 10 and the partition member 20 of the distribution vehicle 1. As shown in FIG. 3, mounting shelves 10 for mounting trays 60 and 65 are attached to both side surfaces of the partition member 20. Specifically, the mounting shelf 10A is provided on the side surface on the side of the warm storage room 8 (see FIG. 2) partitioned by the partition member 20, and the mounting shelf is provided on the side surface on the side of the cold storage room 9 (see FIG. 2). 10B is detachably fixed by screws 19 respectively.

  The mounting shelf 10 includes a substantially rectangular support frame 11 formed by bending a bar, and a support bar 12 fixed to the support frame 11 by welding or the like. The support bar 12 extends in the direction in which the trays 60 and 65 are moved, and is fixed to opposite sides of the support frame 11 on the front side and the back side.

  The support frame 11 and the support bar 12 are support bars that form the skeleton of the mounting shelf 10, and are formed of, for example, a steel round bar. The upper surfaces of the support frame 11 and the support rod 12 constitute a support surface 13 (support line) on which the trays 60 and 65 are placed.

  A support 14 for fixing the support frame 11 to the partition member 20 is fixed to the side of the support frame 11 on the partition member 20 side by welding or the like. On the other hand, a support 16 for supporting the support frame 11 is fixed to the side of the support frame 11 on the wall side of the warm storage room 8 or the cold storage room 9 by welding or the like.

  The support tool 14 and the support tool 16 are metal fittings formed by bending a steel plate material or the like, for example. The support 14 has a substantially U-shaped cross section and extends in the vertical direction. Thereby, the mounting shelf 10 and the partition member 20 can be firmly fixed. On the other hand, the support 16 has a substantially L-shaped cross section and extends in the horizontal direction along the side of the support frame 11.

  And the mounting shelf 10 and the partition member 20 are mounted from the upper side on the support pin 38 (support part) provided in the wall surface side of the warm storage compartment 8 and the refrigerator storage compartment 9 in the state assembled integrally. The That is, the mounting shelf 10 and the partition member 20 are detachably attached to the inside of the storage chamber 7 (see FIG. 2).

  FIG. 4 is an exploded perspective view showing the structure of the mounting shelf 10 and the partition member 20. As shown in FIG. 4, the support pin 38 is provided on the support column 37. Two support columns 37 are fixed to the wall surfaces of the warm storage chamber 8 (see FIG. 2) and the cold storage chamber 9 (see FIG. 2) (the support columns 37 on the warm storage chamber 8 side are not shown). doing). That is, a total of four support columns 37 are provided for each storage chamber 7 (see FIG. 2) partitioned left and right by the partition member 6 (see FIG. 2).

  The support pins 38 are provided so as to be opposed to each other from the facing surfaces of the support columns 37 facing each other with the partition member 20 interposed therebetween. Further, the support pins 38 are provided in two stages with respect to the one-stage partition member 20 by changing the position in the height direction (dimension difference H). That is, in each column 37, the upper support pin 38 </ b> A and the lower support pin 38 </ b> B are provided at a position lower than the upper support pin 38 </ b> A by a predetermined dimensional difference H for each stage of the partition member 20. The predetermined dimensional difference H is the same as the depth H of the concave portion 67 of the duplex tray 65 shown in FIG.

  As described above, the mounting shelf 10 assembled integrally with the partition member 20 is placed on the support pin 38. Specifically, the support 16 fixed to the support frame 11 constituting the mounting shelf 10 is placed on the support pin 38. Here, in the vicinity of the lower ends of the support 16, a recess 17 is formed that opens downward for fitting the support pin 38. Thereby, attachment and detachment and positioning of the mounting shelf 10 are facilitated, and movement of the mounting shelf 10 during use can be prevented.

  Thus, since the two-stage support pins 38A and 38B are provided at different positions in the height direction, the height of the support surface 13 can be increased by changing the support pins 38A and 38B to which the mounting shelf 10 is attached. It can be easily changed.

  Moreover, the screw hole 22 is formed in the both sides | surfaces of the partition member 20 as a fixing | fixed part which fixes the mounting shelf 10 so that attachment or detachment is possible. The screw holes 22 are formed in two stages on the upper and lower sides of the one-stage partition member 20 by changing the position in the height direction (dimension difference H). That is, the partition member 20 at each stage is provided with an upper screw hole 22A and a lower screw hole 22B at a position lower than the upper screw hole 22A by a predetermined dimensional difference H.

  And the mounting shelf 10 is detachably fixed to the both side surfaces of the partition member 20 using the screw hole 22. That is, the screw 19 is inserted into the mounting hole 15 formed in the support 14 of the support frame 11 constituting the mounting shelf 10 and the spacer 40 interposed between the support 14 and the partition member 20, and the screw The mounting shelf 10 is fixed to the partition member 20 by screwing 19 into the screw holes 22.

  Thus, since the partition member 20 is formed with two-stage screw holes 22A and 22B by changing the position in the height direction, by changing the screw holes 22A and 22B to which the mounting shelf 10 is attached, The relative height between the upper surface 21 of the partition member 20 and the support surface 13 can be easily changed.

  Here, when using the flat tray 60 (see FIG. 13), the mounting shelf 10 is fixed to the upper screw hole 22 </ b> A formed in the partition member 20, and the upper support provided in the support column 37. It is mounted on the pin 38A (hereinafter referred to as “first position”).

  On the other hand, when the double tray 65 (see FIG. 14) is used, the mounting shelf 10 is fixed to the lower screw hole 22B formed in the partition member 20, and the lower support provided in the support column 37 is used. It is placed on the pin 38B (hereinafter referred to as “second position”).

  When the first position and the second position are compared, the height of the support surface 13 of the mounting shelf 10 is different. That is, the height of the support surface 13 at the second position is lower than the height of the support surface 13 at the first position by an amount corresponding to the dimensional difference H. On the other hand, the height of the partition member 20 is the same in the first position and the second position.

  Thus, in the allocation vehicle 1 according to the present embodiment, the support surface 13 of the mounting shelf 10 has a first position that is the same height as the upper surface 21 of the partition member 20 and the upper surface 21 of the partition member 20. It can be freely changed to the second position where the predetermined height is low.

  In addition, on the upper part of the partition member 20, a cam body 24 that is biased upward is provided in the vicinity of both front and rear end portions in the tray 60 and 65 insertion / removal direction. A cam member 25 that is biased upward is provided at a substantially central portion of the upper portion of the partition member 20. Details will be described later with reference to FIG.

Next, with reference to FIG.5 and FIG.6, the state which set the mounting shelf 10 in the 1st position is demonstrated in detail.
FIG. 5 is a front view of the vicinity of the partition member 20 showing a state in which the support surface 13 of the mounting shelf 10 is set at the first position. As shown in FIG. 5, at the first position where the mounting shelf 10 is fixed using the upper screw holes 22 </ b> A formed on the side surface of the partition member 20, the support surface 13 of the mounting shelf 10 is separated from the partition member 20. It becomes the same height as the upper surface 21 of.

  The first position is set when the flat tray 60 is used, and the tray 60 is inserted between the upper surface 21 of the partition member 20 and the partition member 20 immediately above the partition member 20, and is kept warm. It is stored across both the storage room 8 and the refrigerated storage room 9. That is, the middle part of the tray 60 is sandwiched between the two upper and lower partition members 20.

  Specifically, a swing member 23 is provided at the lower part of the partition member 20 so as to be swingable and vertically movable. The tray 60 is formed by connecting the upper surface 21 of the partition member 20 and the swing member 23 immediately above the partition member 20. It is inserted between. Here, the support surface 13 of the mounting shelf 10 and the upper surface 21 of the partition member 20 aligned at the same height abut against the bottom surface 63 of the flat tray 60 to support the tray 60.

  FIG. 6 is an explanatory side view showing the internal structure of the partition member 20 and shows a state in which the support surface 13 of the mounting shelf 10 is set at the first position. As shown in FIG. 6, the cam body 24 having a shape corresponding to the shape of the lower surface in the vicinity of the flange portion 61 of the tray 60 is provided in the vicinity of both ends of the upper portion of the partition member 20.

  The cam body 24 is provided so as to be able to swing up and down with the support shaft 33 as a fulcrum. The cam body 24 is moved upward by each tension spring 32 stretched between the lower portion of each cam body 24 and the front end portion or the rear end portion of the partition member 20. It is biased to protrude. Each cam body 24 is normally in a state in which an intermediate portion thereof is in contact with the inner surface of the opening of the partition member 20 located above and a part of the cam body 24 projects upward from the upper surface 21 of the partition member 20.

  Further, a substantially mountain-shaped cam member 25 corresponding to the shape of the lower surface in the vicinity of the flange portion 61 of the tray 60 is provided at substantially the center of the upper portion of the partition member 20. The cam member 25 has a front end portion and a rear end portion attached to fixing portions provided on the partition member 20 via a tension spring 35, and is biased so as to protrude upward.

  The cam member 25 is normally in contact with the peripheral edge of the opening formed on the upper surface 21 of the partition member 20, and the vicinity of the substantially mountain-shaped top is located above the upper surface 21 of the partition member 20 through the opening. It protrudes. Instead of the cam member 25, two swing cams similar to the cam body 24 may be employed.

  The swing member 23 provided at the lower portion of the partition member 20 extends in the tray 60 insertion / removal direction, and a substantially central portion thereof is supported by the support pin 30 so as to be swingable. Moreover, the support hole of the holder which is not shown in figure which supports the both ends of a support pin is formed in the elongate hole shape extended in an up-down direction. Thereby, the rocking | swiveling member 23 is supported so that a vertical movement is possible.

  In addition, a spring holder 31 erected upward and a spring holder 31 wound around the spring holder 31 and sandwiched between the swing member 23 and a spring support piece (not shown) above the spring holder 31 are provided at the approximate center of the upper portion of the swing member 23. A compression spring 29 is provided. The swing member 23 is urged downward by the compression spring 29.

  When the tray 60 is inserted, the swinging member 23 moves up and down to allow the tray 60 to be inserted. When the tray 60 is stored, the swinging member 23 comes into contact with the upper surface of the tray 60 and presses the tray 60 downward. As a result, the tray 60 is elastically sandwiched between the swinging member 23 and the upper surface 21 of the lower partition member 20 with no gap or a slight gap.

  In addition, pressing bodies 26 are provided at both front and rear ends of the swing member 23 in the tray 60 insertion / removal direction. The pressing body 26, together with the cam body 24 and the cam member 25, has a shape matched to the vicinity of the flange portion 61 on the peripheral edge of the tray 60.

  Specifically, the pressing body 26 is provided at both end portions of the swing member 23 so that the mounting direction can be turned upside down, and includes an inclined surface 27 corresponding to the upper surface in the vicinity of the flange portion 61 and a substantially horizontal horizontal plane 28. Have. And in the 1st position, the press body 26 is attached so that the inclined surface 27 may face the downward direction.

  As a result, in the state where the tray 60 is housed, gaps are generated in the vicinity of the flange portion 61 between the engaging slope 27 of the pressing body 26 and the upper surface of the lower cam body 24 or the upper surface of the cam member 25. It is pinched elastically while restraining.

  Next, the operation when the flat tray 60 is stored will be described in detail. In addition, although the distribution vehicle 1 can take in and out the tray 60 from any direction of the front side and the back side, the case where it is inserted from the left side in FIG. 6 will be described as an example.

  When the tray 60 is inserted between the upper and lower partition members 20, the flange portion 61 positioned forward in the insertion direction of the tray 60 comes into contact with the swing member 23 of the upper partition member 20, and the front portion thereof is moved upward. Rotate clockwise while ascending. At the same time, the cam body 24 of the lower partition member 20 is pressed downward by the tray 60 and rotates counterclockwise against the urging force of the tension spring 32 with the support shaft 33 as a fulcrum.

  When the tray 60 is further pushed in, the flange portion 61 on the front side in the insertion direction of the tray 60 passes through the swing member 23 to be in the predetermined storage state described above. That is, the swing member 23 is returned downward by the biasing force of the compression spring 29, and the tray 60 is placed between the lower surface of the swing member 23 biased downward by the compression spring 29 and the upper surface 21 of the partition member 20. Is elastically sandwiched between the two. Thereby, it can suppress that a clearance gap generate | occur | produces in the upper and lower surfaces of tray 60. FIG.

  Further, in the vicinity of the flange portion 61 in the front in the insertion direction, there is no gap between the engaging slope 27 of the pressing body 26 pressed downward by the compression spring 29 and the upper surface of the cam member 25 biased upward by the tension spring 35. Or it is pinched elastically with a slight gap.

  Further, the cam body 24 returns to the original state by the urging force of the tension spring 32 at the rear in the insertion direction. Thereby, the flange 61 on the rear side in the insertion direction, that is, on the front edge side, is the engaging slope 27 of the pressing body 26 pressed downward by the compression spring 29 and the upper surface of the cam body 24 biased upward by the tension spring 32. It is clamped elastically with no gap or a slight gap between them.

  As described above, the tray 60 is elastically sandwiched and supported between the upper and lower partition members 20, thereby preventing a gap from being generated in the tray 60 insertion portion. As a result, mixing of warm air in the warm storage room 8 and cold air in the cold storage room 9 is suppressed.

  Furthermore, in the present embodiment, two trays 60 can be stored side by side (front and back in the loading / unloading direction). In this case, as described above, the first tray 60 may be inserted from either the front surface or the back surface, and then the second tray 60 may be inserted from the other surface.

  In addition, after inserting the first tray 60 from one side of the distribution vehicle 1, the tray 60 is further pushed in to the back in the insertion direction, and then the second tray is placed on the same side. It is also possible to insert from.

  That is, for example, when the tray 60 housed on the front side is further pushed in, the vicinity of the flange portion 61 in the front in the insertion direction opposes the urging force of the tension spring 35 and pushes over the cam member 25 from above. At the same time, the vicinity of the flange 61 in the front in the insertion direction is rotated clockwise while the swinging member 23 on the back side of the upper partition member 20 is raised upward against the urging force of the compression spring 29. . In addition, the vicinity of the flange portion 61 in the rear side in the insertion direction rotates the swing member 23 on the front side of the upper partition member 20 clockwise while raising the front portion against the biasing force of the compression spring 29. .

  When the tray 60 is further pushed in, the front and rear flange portions 61 pass through the front and rear swing members 23, respectively, and each swing member 23 is pushed downward by the urging force of the compression spring 29. Rotate to return to a predetermined position. The cam member 25 is pushed back upward by the urging force of the tension spring 35 and presses the vicinity of the flange portion 61 of the tray 60 from below. As a result, the tray 60 is stored in a predetermined position on the back side without any gap.

  In this way, after the tray 60 inserted from one surface is further pushed in and stored, the second tray 60 can be newly inserted from the same surface. Alternatively, the first tray 60 stored first is pushed in by the second tray 60 newly inserted from the same direction, and the first tray 60 is moved and the second tray 60 is inserted. May be performed simultaneously.

Next, with reference to FIG.7 and FIG.8, the state which set the mounting shelf 10 in the 2nd position is demonstrated in detail.
FIG. 7 is a front view of the vicinity of the partition member 20 showing a state in which the support surface 13 of the mounting shelf 10 is set at the second position. As shown in FIG. 7, in the second position, the mounting shelf 10 is fixed to the partition member 20 using lower screw holes 22 </ b> B formed on the side surface of the partition member 20. Thereby, the height of the support surface 13 of the mounting shelf 10 is lower than the height of the upper surface 21 of the partition member 20 by a predetermined dimension (dimension difference H).

  As described above, the second position is set when the duplex tray 65 is used. When the double tray 65 is used, the concave portion 67 serving as a boundary between the two regions 65A and 65B of the tray 65 is formed between the upper surface 21 of the partition member 20 and the swing member 23 immediately above it. It is inserted. That is, the upper and lower partition members 20 sandwich the recess 67 formed in the intermediate portion of the tray 65.

  The tray 65 is stored across both the warm storage room 8 and the cold storage room 9. That is, one area 65 </ b> A of the tray 65 is stored in the warm storage room 8, and the other area 65 </ b> B is stored in the cold storage room 9.

  Here, the support surface 13 of the mounting shelf 10 and the upper surface 21 of the partition member 20 are different in height by a predetermined dimensional difference H, and the support surface 13 is lower. The predetermined dimensional difference H is equal to the depth H of the concave portion of the tray 65.

  Thereby, the upper surface 21 of the partition member 20 contacts and supports the bottom surface 69 of the concave portion 67 of the duplex tray 65, and the support surface 13 of the mounting shelf 10 contacts and contacts the bottom surface 68 of the tray 65. Support both sides of 65.

  FIG. 8 is an explanatory side view showing the internal structure of the partition member 20 in a state where the support surface 13 of the mounting shelf 10 is set at the second position. The pressing body 26 has a horizontal surface corresponding to the edge shape of the inclined surface 27 corresponding to the edge shape of the flat tray 60 (see FIG. 13) or the recessed portion 67 of the tray 65 by changing the mounting direction. 28 can be switched.

  As shown in FIG. 8, in the second position, the pressing body 26 is attached to both ends of the swing member 23 so that the horizontal plane 28 is on the lower side. As a result, a substantially horizontal and flat surface that is continuous from the horizontal surface 28 that is the lower surface of the pressing body 26 to the lower surface of the swing member 23 is formed.

  In a state where the tray 65 is stored in a predetermined position, a substantially flat surface constituted by the horizontal surface 28 of the pressing body 26 and the lower surface of the swinging member 23 abuts on the upper surface of the recess 67 and is urged by the urging force of the compression spring 29. The tray 60 is pressed downward. The tray 60 is elastically sandwiched between the swing member 23 and the upper surface 21 of the partition member 20 at the lower stage thereof, thereby suppressing the generation of a gap.

  As described above, in the allocation vehicle 1, even if the type of the trays 60 and 65 is changed from the flat tray 60 to the double tray 65, the gap generated in the vicinity of the edge of the tray 65 can be suitably closed. As a result, heat loss between the warm storage room 8 (see FIG. 2) and the cold storage room 9 (see FIG. 2) can be reduced.

  Moreover, in the 2nd position, the cam body 24 provided in the vicinity of the both ends of the upper part of the partition member 20 will be in the lowered state. Specifically, the partition member 20 includes an adjustment screw 34 that presses the upper middle portion of the cam body 24, and the cam body 24 is pushed downward by screwing the adjustment screw 34 downward.

  That is, the adjustment screw 34 is screwed downward and the upper intermediate portion of the cam body 24 is pressed downward, so that the cam body 24 rotates against the urging force of the tension spring 32 with the support shaft 33 as a fulcrum. . Thereby, the protrusion of the cam body 24 upward becomes small. As a result, when the tray 65 is inserted, the cam body 24 does not hinder the entry of the recess 67, so that the tray 65 can be easily inserted.

  Further, in the second position, the cam member 25 provided at substantially the center of the upper portion of the partition member 20 is pressed by the pressing portion 26 and moves downward. That is, the cam member 25 is pushed downward by the urging force of the compression spring 29 and is pushed against the urging force of the tension spring 35.

  If the swing member 23 is not pushed upward by the cam member 25, a part of the cam member 25 may protrude above the upper surface 21 of the partition member 20. When the tray 65 is inserted, the cam member 25 is moved downward by being pressed by the tray 65, so that the passage of the tray 65 is allowed.

  As described above, the swing member 23 is supported so as to be swingable and vertically movable. The operation of the swing member 23 when inserting the tray 65 is the same as the operation when inserting the flat tray 60.

  However, in the duplex tray 65, since the concave portion 67 is inserted between the upper and lower partition members 20, the amount of movement of the swing member 23 is small compared to the case where the flat tray 60 is used. That is, the swing member 23 rotates and moves up and down so as to ensure a gap corresponding to the thickness of the recess 67.

Next, with reference to FIGS. 9 and 10, the lowermost mounting shelf 10 </ b> C will be described in detail.
FIG. 9 is a perspective view showing the lowermost loading shelf 10C. As shown in FIG. 9, the lowermost mounting shelf 10 </ b> C has a support frame 41 formed by bending a bar, a support bar 42 fixed to the support frame 41, and a support bar 42 that is freely rotatable. And a leg body 45 supported by the body.

  The support frame 41 is formed by bending from, for example, a steel round bar or the like, and has a substantially U-shape when viewed from above. Both end portions of the support frame 41 are inserted and supported in support holes 39 formed in the support column 37. Further, a leg portion 44 that is bent downward is formed on one side of the support frame 41 that extends in the tray 60 and 65 (see FIGS. 13 and 14).

  The support bar 42 is formed of, for example, a steel round bar or the like, and extends substantially linearly in the direction in which the trays 60 and 65 are moved. Both end portions of the support bar 42 are fixed to opposite sides of the support frame 41 on the front side and the back side by welding or the like.

  The leg body 45 has, for example, a substantially U-shape formed by bending a steel round bar or the like, and support portions 46 that are rotatably attached to the support rod 42 at both ends thereof. Have. The support part 46 is comprised from the substantially cylindrical member, for example, and the support bar 42 is rotatably inserted by the internal diameter side. The upper surface of the support portion 46 constitutes a support surface 43 (support line) for placing the trays 60 and 65.

  A support hole 39 is formed in the column 37 as a fixing portion for inserting both ends of the support frame 41. The support hole 39 is formed in two stages vertically by changing the position in the height direction (dimension difference H). In other words, each support column 37 is formed with an upper support hole 39A and a lower support hole 39B at a position lower than the upper support hole 39A by a predetermined dimensional difference H.

  Thus, since the two-stage support holes 39A and 39B are formed by changing the position in the height direction, the height of the support surface 43 is changed by changing the support holes 39A and 39B to which the mounting shelf 10C is attached. Can be easily changed.

  10 (A) and 10 (B) are front views of the lowermost mounting shelf 10C (viewed in the direction of arrow A shown in FIG. 9), and FIG. 10 (A) shows the support surface 43 of the mounting shelf 10C. FIG. 10B shows a state where the support surface 43 of the mounting shelf 10C is set at the second position.

And the lower part of the leg body 45 is placed on the floor 49 with the lower part of the leg 45 facing the partition member 20.

  A part of the leg body 45 abuts on the lower end part of the leg part 44 of the support frame 41 bent downward, and the leg body 45 is restricted from further rotation. In other words, the leg body 45 is supported from above by the support portions 46 at both ends rotatably supported by the support rod 12 and the intermediate portion abutting against the leg portions 44. And the lower end part vicinity of the leg body 45 contact | abuts to the floor surface 49 of the storage chamber 7, and is supported there. That is, a part of the load by the tray 60 placed on the placing shelf 10 </ b> C is received by the floor 49.

  By mounting the mounting shelf 10C in such a state, the height of the support surface 43 of the mounting shelf 10C becomes the same height as the upper surface 21B of the lowermost partition member 20B at the first position. Accordingly, the tray 60 can be supported by bringing the bottom surface 63 (see FIG. 13) of the flat tray 60 into contact with the support surface 43 of the mounting shelf 10C and the upper surface 21B of the lowermost partition member 20B. .

  Note that both end portions of the support frame 41 are slightly bent upward. This facilitates the operation of inserting the support frame 41 into the support hole 39 and prevents the support frame 41 from moving from the support hole 39 by moving in the horizontal direction in the state of use. .

  As shown in FIG. 10B, in the second position where the double tray 65 (see FIG. 14) is used, both ends of the mounting shelf 10C are inserted into the lower support holes 39B formed in the support column 37. It is inserted and placed on the floor 49 with the lower part of the leg body 45 facing the column 37.

  Thereby, the lower end part of the leg part 44 of the support frame 41 bent downward is contact | abutted to the floor surface 49, and is supported there. Note that the leg body 45 rotated in the direction of the support column 37 does not function as a leg that supports the load of the mounting shelf 10C in the second position.

  By mounting the mounting shelf 10C in such a state, at the second position, the height of the support surface 43 of the mounting shelf 10C is a predetermined dimension (dimension) than the upper surface 21B of the lowermost partition member 20B. Difference H) decreases.

  Thus, the bottom surface 69 (see FIG. 14) of the recess 67 (see FIG. 14) of the duplex tray 65 is brought into contact with and supported by the top surface 21B of the lowermost partition member 20B, and the bottom surface 68 of the tray 65 (see FIG. 14). 14) can be supported by contacting the support surface 43 of the mounting shelf 10C.

  As described above, in the allocation vehicle 1, the lowermost loading shelf 10 </ b> C is pulled out from the support hole 39 of the support column 37, the leg body 45 is rotated to change its orientation, and the support frame 41 is supported at another height. By reinserting the holes 39, the height of the support surface 43 can be easily changed.
