  In the configuration of the conventional cargo handling pallet as described above, when the side panel comes into contact with the engaging member attached to the outer edge of the load support base (side panel support portion) so as to protrude outward, the side Even if the panel is configured not to protrude outward from the outer edge of the load support base (side panel support portion) in plan view, the engaging member itself is the outer edge of the load support base (side panel support portion). Since it protrudes outward from the pallet for cargo handling, a side guide provided for regulating the pallet transport path in the cargo handling pallet transport line and other engaging members and the engaging member may interfere with each other. There was a fear of coming.

  The object of the present invention is to provide a foldable cargo handling pallet capable of solving the conventional problems as described above, and the foldable cargo handling pallet according to claim 1 will be described later. When shown with reference numerals in the embodiment, the load support stand 1, a back panel 4 erected on the rear side of the load support stand 1 so as to be foldable on the load support stand 1, and the back panel 4 Side panels 2 and 3 that are foldably connected so as to overlap the back panel 4 on both the left and right sides of the side, and the load support base 1 includes a side that supports the lower side of the side panels 2 and 3. A collapsible cargo handling pallet provided with a panel support 20 and an engagement member 21 for preventing the side panels 2 and 3 supported by the side panel support 20 from moving outward. The joint member 21 is In a plan view, the inner side surface of the engaging member 21 is attached in a state of entering the inner side from the outer edge (outer side surface of the front-rear direction frame member 14) of the side panel support portion 20 of the load support base 1. .

  In carrying out the present invention having the above-described configuration, specifically, as described in claim 2, the side panels 2 and 3 have a mesh structure, and the lower side of the side panels 2 and 3 has a lower end of each vertical wire 19. The horizontal wire 18b is disposed only on the inner side, and the engaging member 21 is located between two adjacent vertical wires 19 of the side panels 2 and 3 in a side view, and the side panels 2 and 3 The outer side of the side panels 2 and 3 can be prevented from moving by the contact between the horizontal wire 18b on the lower side of the side panels 2 and 3 and the engaging member 21.

  The engaging member 21 may be configured by arranging a wire having an appropriate thickness in parallel with the length direction of the lower side of the side panels 2 and 3, but a bent wire or plate or the like may be used. When the engaging member 21 according to the second aspect is configured, the engaging member 21 is located above the horizontal wire 18b on the lower side of the side panels 2 and 3, as described in the third aspect. The engaging member 21 can be inclined so as to enter the inner side toward the upper end side. In addition, as described in claim 4, the load support base 1 has a configuration in which front and rear direction frame members 14 to which the engaging members 21 are attached are provided on both left and right sides, and the front and rear direction frame members 14 include: A recessed portion 23 whose outer surface is recessed inward at a position where the engaging member 21 is attached can be formed, and the leg portion 21 a of the engaging member 21 can be attached to the outer surface in the recessed portion 23. In this case, as described in claim 5, the engagement member 21 is formed by bending a wire rod into an inverted U shape, and both vertical shaft portions 22 a and 22 b are formed in a front-rear direction frame of the load support base 1. It can be attached to the outer surface in the recessed portion 23 formed in the material 14.

  Furthermore, as described in claim 6, the load support base 1 has side panels 2, 3 supported by the side panel support part 20 at positions inside the side panel support parts 20 on both left and right sides. It is possible to provide an inner side panel positioning portion 24 that prevents inward movement but can be moved inward by lifting the side panels 2 and 3. In this case, as described in claim 7, the load support base 1 includes a frame structure 1 </ b> A including a front-rear direction frame member 14 on both left and right sides, and a mesh structure overlaid on the frame structure 1 </ b> A. 1B, and the side panel support portion 20 is provided on the front / rear direction frame member 14 of the frame structure 1A that protrudes outward from the mesh structure 1B and is formed on the outer surface of the front / rear direction frame member 14. The engaging member 21 is attached to the outer side surface of the recessed portion 23, and the inner side panel positioning portion 24 can be constituted by the side of the mesh structure 1B.

  According to the foldable cargo handling pallet according to the first aspect of the present invention, in the assembled cargo handling pallet, the side panel moves outward from a substantially right-angled forward orientation with respect to the back panel ( Opening) can be prevented by the engagement member on the load support base side, and the engagement member has a side panel support portion on the load support base side on the inner side surface of the engagement member in plan view. Therefore, the engaging member does not protrude at all from the outer surface of the load supporting base in a plan view, or the protruding amount can be reduced. Of course, when the side panel that moves to the outside is blocked by the engaging member, there is a member (for example, a wire rod for a mesh-structured side panel) that protrudes outside the contact portion of the side panel with the engaging member. In this case, the member is positioned outside the inner surface of the engaging member. At this time, the member on the side panel side does not protrude at all from the outer surface of the load support base or the protrusion thereof. The amount can be kept small. Therefore, other equipment-side members, such as side guides provided to regulate the pallet transport path in this cargo handling pallet transport line, are in contact with or caught by the engaging members and the side panels moved outward. The possibility of causing trouble can be eliminated or the influence can be reduced.

  When the side panel has a mesh structure, by adopting the configuration according to claim 2, when the side panel moves to the outside, each vertical wire constituting the side panel and the engagement member are in contact with each other. The engaging member enters relatively between two adjacent vertical wires, and the engaging member comes into contact with the horizontal wire arranged only inside the lower end of each vertical wire. become. Therefore, when the engagement member is wider than the interval between the two vertical wires and the side panel to be moved outward is received by the engagement member, the engagement member is located outside the vertical wire of the side panel. Compared with the configuration in contact, the width of the engaging member can be narrowed to reduce the size and weight, thereby reducing the cost. Further, if the difference between the width of the engaging member and the distance between two adjacent vertical wires on the side panel side is reduced, the engaging member fits between the two adjacent vertical wires on the side panel side. In this state, the position of the side panel in the front-rear direction is also restricted. Even if the connecting means between the back panel and the side panel has a structure with a very large play in the front-rear direction such as a coil hinge, the side panel The rattling can be kept small, and this kind of cargo handling pallet can be safely stacked. Furthermore, in the configuration of the present invention, when the engaging member abuts on a member located on the outermost side of the side panel (for example, the outer horizontal wire of the side panel described in Patent Document 1), the side of the side panel is placed on the load support base side. A dead space (a dead space having a width equal to the amount by which the engaging member enters the inner side from the outer edge of the side panel support part on the load support base side) is generated on the outside. According to the configuration of claim 2, Since such dead space does not occur or can be reduced, the lateral width of the load support base is minimized relative to the lateral width of the load storage space between the side panels, and the cargo handling pallet is reduced in size and weight. be able to.

  When carrying out the present invention described in claim 2, according to the structure described in claim 3, when the side panel to be moved outward is received by the engaging member, the engaging member is In addition to coming into contact with the horizontal wire on the lower side, the engaging member covers the horizontal wire on the lower side of the side panel so that it deeply enters between two adjacent vertical wires on the side panel. Therefore, even in a situation where an external force acts on the side panel, an effect of ensuring the positioning effect in the front-rear direction with respect to the side panel can be obtained.

  When carrying out the present invention according to any one of claims 1 to 3, the engaging member can be provided at a position closer to the outer side on the upper surface of the front-rear direction frame material on the left and right sides of the load support base. According to the configuration described in No. 4, the engagement member is mounted on the load support base side in the same manner as in the case of welding the both in the state where the legs of the engagement member are in contact with the outer side surface of the front-rear direction frame member. It is possible to simply and strongly weld and fix the frame member in the front-rear direction, and the engagement member can enter the inside from the outer side surface of the front-rear direction frame member on the load support base side to achieve the intended purpose.

  Moreover, although the said engaging member used in this invention can also be comprised from the board | plate material etc. which formed the rib for reinforcement as needed, according to the structure of Claim 5, the said engaging member is a wire. Thus, it can be easily and lightly configured by bending, and the cost can be reduced.

  Furthermore, according to the structure of claim 6, in the cargo handling pallet in a use state in which the side panel is in a substantially perpendicular front-facing posture with respect to the back panel, the side panel moves (opens) to the outside. Since the inner side panel positioning part can also prevent the inner side panel from moving (closed), for example, the side panel is an inner folding type cargo handling pallet or the side panel is an outer folding type cargo handling pallet. In an external folding type cargo handling pallet in which the side panel can rotate inward from a posture that is substantially perpendicular to the back panel, when the load is empty or when the load is loaded, Even in situations where inward movement (closing movement) cannot be completely prevented, the side panel can be securely held in its intended position. Stacking of cargo pallet of utilizing side panel can also be performed easily and safely. In this case, according to the structure of Claim 7, compared with the case where the said inner side panel positioning part is comprised by a separate member, a number of parts can be reduced and cost reduction can be aimed at.

  A specific embodiment in which the load support base according to the present invention is used as a load support base for a foldable box-type pallet will be described with reference to the accompanying drawings. In FIGS. Tables 2 and 3 are side panels that stand up from the left and right sides of the load support table 1, 4 is a back panel that stands up from the rear side of the load support table 1, and 5 is openable and closable that stands up from the front side of the load support table 1.

The side panels 2 and 3 are connected to the left and right sides of the back panel 4 via coil hinges 7 so as to be foldable so as to overlap the inside of the back panel 4. The back panel 4 is L-shaped in a side view and includes a bent bottom side portion 8 that is continuously bent from the lower end to the inside at a right angle, and a load support base 1 by a hinge 9 at the tip of the bent bottom side portion 8. It is connected up and down freely.

  The gate panel 5 includes a lower gate portion 5a and an upper gate portion 5b connected to the upper side of the lower gate portion 5a by a hinge 10 so as to be freely opened and closed in the front-rear direction. The lower side of the lower gate portion 5a is a load support base. 1 is connected to the front side of 1 by a coil hinge 11 so as to be raised and lowered. Then, four engagements for engaging the upper ends of the left and right sides of the lower panel portion 5a of the gate panel 5 and the upper ends of the left and right sides of the upper panel portion 5b, which are vertically erected, with the front sides of the side panels 2 and 3, respectively. Stop means 12 is provided.

  As shown in FIG. 3, the load support base 1 includes a frame structure 1 </ b> A as a strength member and a mesh structure 1 </ b> B as a load support surface material (load spill prevention material) mounted and fixed thereon. Has been. The frame structure 1A includes a front-rear frame member 14 disposed on both left and right sides of the load support base 1 and a plurality of left-right frame members 15 that connect and integrate the front-rear frame members 14 to each other. The legs 6 are fixed to the lower side of the frame structure 1A. The front-rear frame member 14 and the left-right frame member 15 are composed of square pipe members having appropriate thicknesses. However, it is also possible to use a groove member with a lower opening or a groove member with an upper opening. It is. The mesh structure 1B is configured by a front-rear direction wire 16 and a left-right direction wire 17, and in the illustrated embodiment, the left-right direction wire 17 is disposed on the front-rear direction wire 16 arranged in parallel at substantially equal intervals in the left-right direction. Are arranged at appropriate intervals in the front-rear direction, and a mesh having substantially the same size is formed on the entire surface of the mesh structure 1B together with the left-right frame member 15 of the frame structure 1A.

  The side panels 2 and 3, the back panel 4, and the gate panel 5 all have a mesh structure composed of a vertical wire and a horizontal wire, and are located horizontally at the tip of the bent bottom portion 8 of the back panel 4. The left-right direction wire 8a is pivotally attached by the hinge 9 fixed to the left-right direction frame material 15 in the frame structure 1A of the load support base 1 positioned directly below the horizontal left-right direction wire 8a. The lower panel portion 5a of the gate panel 5 has a horizontal horizontal wire rod at the lowermost end thereof undulated by a coil hinge 11 on a horizontal wire rod 17a at the front end of the mesh structure 1B of the load support base 1 located immediately below the gate panel 5a. It is pivotally attached freely.

  The side panels 2 and 3 have a mesh structure composed of an inner horizontal wire 18 and an outer vertical wire 19, and a reinforcing horizontal wire 18 a is disposed on the outer side of each vertical wire 19 only at the uppermost end. 2B, when the cargo handling pallet is stacked with the upper pallet legs 6 placed on the left and right side panels 2 and 3 of the lower pallet, the upper pallet legs. The reinforcing vertical wire 19 a is also added to the inside of the horizontal wire 18 in the two regions in the vicinity of the front and rear ends of the side panels 2, 3. Accordingly, the horizontal wire 18b is disposed only on the inner side of each vertical wire 19 on the lower side of the side panels 2 and 3, and the lower ends of the horizontal wire 18b and each vertical wire 19 and 19a are below the side panels 2 and 3. It constitutes the side.

  On the other hand, the front and rear frame members 14 on the left and right sides of the frame structure 1A of the load support base 1 support the front and rear wires 16a on the left and right sides of the mesh structure 1B near the inner side. The front and rear belt-shaped upper surfaces projecting outward from the left and right sides of the body 1B constitute the side panel support 20. The side panels 2 and 3 facing forward at right angles to the back panel 4 are supported by the side panel support 20 at the lower side, that is, the lower ends of the horizontal wire 18b and the vertical wires 19 and 19a. At this time, the movement of the side panels 2 and 3 (close movement) means that the side of the mesh structure 1B that is higher than the side panel support portion 20 (the upper surface of the front-rear direction frame member 14), that is, the front-rear direction. Each reinforcing vertical wire positioned on the lower side of the side panels 2 and 3, specifically, on the inner side of the horizontal wire 18 b, on the side of the mesh structure 1 </ b> B formed by the end surfaces of the wire 16 a and the left and right wires 17. When the inner side of the lower end of 19a and the side panels 2 and 3 are bent inward, the horizontal wire 18b is prevented from contacting. That is, the left and right sides of the mesh structure 1B constitute the inner side panel positioning portion 24.

  In order to prevent the side panels 2 and 3 facing forward at right angles to the back panel 4 from moving (opening) outward from the side panel support portion 20 on the load support base 1 side, both left and right sides of the load support base 1 An engagement member 21 is attached to the. That is, as shown in FIG. 3, on the outer surface of the front-rear frame member 14 on the left and right sides of the frame structure 1A of the load support base 1, in other words, on the outer edge of the side panel support portion 20, there are two front and rear portions. An engagement member 21 that protrudes upward from the support surface of the side panel support portion 20 (the upper surface of the front-rear direction frame member 14) is attached. The detailed structure will be described with reference to FIGS. 4 to 6. The engaging member 21 is formed by bending a wire rod into an inverted U shape, and the lower half portions of both vertical shaft portions 22a and 22b are mounting leg portions. 21a.

  On the other hand, the portion of the front-rear frame member 14 to which the engaging member 21 is attached is formed by pressing a recess 23 having a width that can just fit the mounting leg 21a of the engaging member 21. The mounting leg portion 21a of the engaging member 21, that is, the lower half portions of the vertical shaft portions 22a and 22b are fixed to the outer surface of the insertion portion 23 by welding. Thus, the depth of the recessed portion 23 can be made equal to the diameter of the wire constituting the engaging member 21, but in the illustrated example, it is slightly shallower than the diameter of the wire constituting the engaging member 21. It is substantially the same as the protruding height of the horizontal wires 18, 18b from the vertical wires 19 of the panels 2, 3. The engaging member 21 is formed to have a width narrower than the interval between the two adjacent vertical wires 19 of the side panels 2 and 3, and the mounting position thereof is 2 adjacent to the side panels 2 and 3 in a side view. The engaging member 21 is set so as to be positioned in the middle of the two vertical wire rods 19. Further, the engagement member 21 is configured to have a height that overlaps only with the horizontal wire 18b on the lower side of the side panels 2 and 3 and does not overlap with the second horizontal wire 18 from the bottom in a side view. The recessed portion 23 may be formed over the entire height from the upper surface to the lower surface of the front / rear direction frame member 14, but as shown in FIG. 6B, the recessed portion is slightly above the lower surface of the front / rear direction frame member 14. If the lower end 23a of the engaging member 21 is formed, the lower end of the mounting leg portion 21a of the engaging member 21 can be positioned by the lower end 23a of the recessed portion 23, so that the engaging member 21 can be easily attached by welding. .

  In the assembled state shown in FIG. 1, the cargo handling pallet having the above configuration is used for transporting and storing by storing the load in the load storage space on the load support base 1 surrounded by the panels 2 to 5. However, when taking out the load, the locking means 12 can be released, and the entire gate panel 5 or only the upper gate panel portion 5b can be turned forward to open the front side of the load storage space. The cargo handling pallet in this assembled state is formed by fitting the left and right side legs 6 of the upper pallet to the upper sides of the left and right side panels 2 and 3 of the lower pallet, as indicated by phantom lines in FIG. Can be stacked. In this assembled cargo handling pallet, the lower sides of the left and right side panels 2 and 3 are stably supported by the side panel support portion 20 (upper surface of the front and rear direction frame member 14) on the load support base 1 side. In this state, the side panels 2 and 3 are prevented from moving (opening) outward by the two front and rear engaging members 21 and the side panels 2 and 3 are moved inward (closed). Since both the left and right sides of the mesh structure 1B in the load support base 1, that is, the inner side panel positioning portions 24, are blocked, the side panels 2 and 3 are surely placed in a right-angled front posture with respect to the back panel 4. Retained.

  As described above, when the side panels 2 and 3 are moved (opened) from the posture perpendicular to the back panel 4 to the outside, the side panels 2 and 3 are placed on the side panel support portion 20 on the load support base 1 side. The two front and rear engaging members 21 prevent the two front and rear engaging members 21 from falling off from the outside, but at this time, as shown in FIGS. 7 and 8, between the two adjacent vertical wires 19 of the side panels 2 and 3. Since the engaging member 21 comes into contact with the horizontal wire 18b on the lower side of the side panel, the vertical wires 19 located on the outermost sides of the side panels 2 and 3 are arranged on the left and right outer sides of the load support base 1, that is, the frame. It can be configured such that it does not project outward beyond the virtual vertical plane including the outer surface of the front-rear frame member 14 located on the left and right sides of the structure 1A, or the projecting amount is minimal.

  The unused cargo handling pallet is folded so that the locking means 12 is released and the gate panel 5 is stacked on the load support base 1, and the left and right side panels 2, 3 are folded inside the back panel 4. By folding the back panel 4 so as to overlap the load support base 1, the folding bottom side part 8 whose height on the load support base 1 is in the vertical posture of the folded back panel 4 positioned at the uppermost position. Can be reduced to a height equivalent to

  When the side panels 2 and 3 are folded so as to overlap the inside of the back panel 4, the back panel 4 is tilted backward together with the side panels 2 and 3, and the lower sides of both side panels 2 and 3 are placed on the load support base 1 side. Even if the gate panel 5 is first folded on the load support base 1 by separating it upward and rearward from the side panel support portion 20, the mesh structure 1B of the gate panel 5 and the load support base 1 (the side Both side panels 2 and 3 can be folded so as to overlap the inner side of the back panel 4 without being affected by the inner side panel positioning portion 24). Of course, the side panels 2 and 3 can be folded so as to overlap the inside of the back panel 4 with the gate panel 5 tilted outward. In this case, the side panels 2 and 3 are lifted up a little by using the vertical play at the coil hinge 7 connecting the back panel 4 and the side panels 2 or 3, or the back panel together with the side panels 2 and 3 is used. 4 is slightly tilted rearward, and the lower side of the side panels 2 and 3 may be lifted slightly from the inner side panel positioning portion 24 (side of the mesh structure 1B) on the load support base 1 side.

  In addition, although the side panel support part 20 provided in the left-right both sides of the load support stand 1 was comprised by the upper surface of the front-back direction frame material 14 in 1 A of frame structures, it is not limited to this. For example, when the left and right sides of the mesh structure 1B of the load support base 1 are overlapped on the front and rear frame 14 on the left and right sides of the frame structure 1A, the sides are placed on the left and right sides of the mesh structure 1B. The panel support part 20 can also be formed. In this case, the inner side panel positioning portion 24 can be configured by a separate member attached on the mesh structure 1B. Of course, the inner side panel positioning portion 24 is not essential to the present invention, and may be omitted in some cases. When the side panel support portion 20 is provided on the front-rear direction frame member 14 in the frame structure 1A and the front-rear direction frame member 14 has no surface for supporting the side panels 2 and 3, for example, the front-rear direction frame member 14 is on the upper side. In the case of an open channel shape member, another member constituting the side panel support portion 20 may be attached to the front-rear frame member 14.

  Further, when the inner side panel positioning portion 24 is also provided, in the illustrated embodiment, the effective width of the side panel support portion 20, that is, the interval between the engaging member 21 and the inner side panel positioning portion 24 is the side panel. The horizontal wire 18b with respect to the thickness at the portion adjacent to the engaging member 21 on the lower side of the two or three (the distance in the left-right direction between the outer surface of the horizontal wire 18b and the inner surface of the reinforcing vertical wire 19a). However, the gap between the engaging member 21 and the inner side panel positioning portion 24 is narrowed, and the lower sides of the side panels 2 and 3 supported by the side panel support portion 20 are configured. The sides can be sandwiched between the engaging member 21 and the inner side panel positioning portion 24 so that there is almost no play in the left and right lateral directions of the side panels 2 and 3. In this case, the side panels 2 and 3 and the back panel 4 are made wider by increasing the width of the engaging member 21 to just fit between the two adjacent vertical wires 19 on the side panels 2 and 3 side. Even if the play in the horizontal direction at the coil hinge 7 to be connected is large, the play in the front-rear direction of the side panels 2 and 3 supported by the side panel support part 20 on the load support base 1 side can be eliminated or reduced.

  Furthermore, although the engaging member 21 has a relatively narrow width, if it is configured to have a sufficiently large buckling strength against a vertical load, it can also serve as a stacking support member for a folded cargo handling pallet. Is also possible. Further, the side panels 2 and 3 are lifted upward and rearward together with the back panel 4, so that the side panels 2 and 3 are rotated outward without being obstructed by the engaging member 21, and folded so as to overlap the outside of the back panel 4. You can also

  In the above embodiment, as shown in FIG. 5, the engagement member 21 that fits between the two vertical wires 19 is compared with the interval between the two adjacent vertical wires 19 of the side panels 2 and 3. As shown in FIG. 9, the width of the engaging member 21 is set between the two vertical wires 19 on the side panels 2 and 3 into which the engaging member 21 is fitted. As shown in FIG. 10, the side panels 2 and 3 to be moved outward are brought into contact with the engaging member 21 and the horizontal wire 18b on the lower side, as shown in FIG. When received, the side panels 2 and 3 move in the front-rear direction (the length direction of the lower side of the side panels 2 and 3) between the engaging member 21 and the vertical wire 19 positioned in the front-rear direction. Suppressed by contact, position the side panels 2 and 3 in a substantially fixed position in the front-rear direction It can be.

  Further, as shown in the above embodiment, the side panels 2 and 3 to be moved outward are engaged with the engaging members 21 and the side members that are fitted between the two adjacent vertical wires 19 of the side panels 2 and 3. When receiving by contact with the horizontal wire 18b on the lower side of the panel, as shown in FIG. 11, the rising portion of the engaging member 21 protruding above the horizontal wire 18b on the lower side of the side panel, that is, the side panel By inclining the engaging action portion 21b protruding upward from the support portion 20 so as to enter the inside, the engaging depth in the inside and outside directions of the engaging member 21 and the side panels 2 and 3 is increased. The positioning effect in the front-rear direction with respect to the side panels 2 and 3 that are prevented from moving outward by the member 21 can be further enhanced.

  As shown in FIG. 12, the engaging member 21 bends the mounting legs 22a and 22b horizontally inward, and mounts the mounting legs 22a and 22b on the front-rear direction frame member 14 of the frame structure 1A.
