The vertical side wall u1a in which the lock portion u2 of the square tube portion u1 of the lock member U is formed exceeds the tip e6a of the abutting elastic tongue piece e6 of the abutting member E. When the contact elastic tongue e6 of the abutting member E is elastically restored, at least the free end portion of the contact elastic tongue e6 of the abutting member E is located in the arrangement space A. It will return to the original position which protruded outside beyond the outer surface 1a1 of the shape part 1a. Further, in this state, the distal end portion of the lock portion u2 of the lock member U is inserted into the end portion vertical rib 1f located in the arrangement space A and the lock portion insertion through hole 1k formed in the reinforcing block 1j. In addition, the tip of the lock portion u2 is configured not to protrude outward beyond the end vertical rib 1f. Furthermore, in this state, as shown in FIG. 22, the guide protrusion u5 formed on the opposing horizontal side wall u1b of the rectangular tube portion u1 of the lock member U is an upper portion constituting the arrangement space A. It is located behind the upper guide rail 1s formed on the lower surface 1h1 of the horizontal partition rib 1h and the lower guide rail 1t formed on the upper surface 1i1 of the lower horizontal partition rib 1i and overlaps with each other when viewed from the front. It is configured. In this way, the lock member U is attached in the arrangement space A formed in the preceding inclined side wall 1. When the lock member U is moved in the direction of the end vertical rib 1f, a notch portion formed in the vertical side wall u1a where the lock portion u2 of the rectangular tube portion u1 constituting the lock member U is not formed. Since the contact elastic tongue piece e6 of the abutting member E is inserted through u3, the abutting elastic tongue piece of the abutting member E is formed on the vertical side wall u1a where the lock portion u2 is not formed. e6 does not come into contact.

  As shown in FIG. 32, the inner surface u1a ′ positioned in the rectangular tube portion u1 of the vertical side wall u1a in which the lock portion u2 of the rectangular tube portion u1 constituting the lock member U is formed is an abutting member E. When the contact elastic tongue piece e6 is in contact with the tip end e6a of the contact elastic tongue piece e6 or close to the tip end e6a of the contact elastic tongue piece e6, the distal end portion of the lock portion u2 of the lock member U is in the arrangement space A.

It is configured. In this state, even if the lock member U is moved in the direction of the end-side vertical rib 1g, the inner surface u1a ′ located in the rectangular tube portion u1 of the vertical side wall u1a in which the lock portion u2 is formed is Therefore, the lock member U moves in the direction of the end-side vertical rib 1g, and the lock portion u2 of the lock member U is connected to the end of the reinforcing block 1j. It is possible to prevent the lock member U from coming out of the arrangement space A by coming out of the lock part insertion through hole 1k formed in the part vertical rib 1f. Such a state or position of the lock member U is referred to as a release state of the lock member U or a release position of the lock member U. Furthermore, in the release position of the lock member U, the locking elastic tongue piece u4 formed in the lock portion u2 is not inserted into the lock portion insertion through hole 1k.

  When the rectangular tube portion u1 of the lock member U is moved in the direction of the reinforcing block 1j from the unlocking position of the lock member U described above, the locking protrusion u4a of the locking elastic tongue piece u4 formed on the lock portion u2 is The locking projection insertion hole 1k is inserted into the locking portion insertion through-hole 1k, and the locking projection u4a of the locking elastic tongue piece u4 is brought into contact with the outer vertical inner surface 1k2 of the locking portion insertion through-hole 1k. It will be elastically deformed against the force in the direction of the inner vertical inner surface 1k1. Further, when the square tube portion u1 of the lock member U is moved in the direction of the reinforcing block 1j, the tip end portion of the lock portion u2 of the lock member U exceeds the end vertical rib 1f as shown in FIG. When the locking projection u4a of the locking elastic tongue piece u4 reaches the locking recess 1k5 formed in the outer vertical inner surface 1k2 of the locking portion insertion through hole 1k, the locking elastic tongue The piece u4 is rotated in the direction of the external vertical inner surface 1k2 by its elastic restoring force, and the locking projection u4a of the locking elastic tongue piece u4 is formed on the external vertical inner surface 1k2 of the lock portion insertion through hole 1k. It will be engaged with the locking recess 1k5. Such a state or position of the lock member U is referred to as a lock state of the lock member U or a lock position of the lock member U. At the locking position of the locking member U, the locking projection u4a of the locking elastic tongue u4 formed on the locking portion u2 of the locking member U is a locking portion formed in the reinforcing block 1j and the end vertical rib 1f. Since it is engaged with the locking recess 1k5 formed in the outer vertical inner surface 1k2 of the insertion through hole 1k, the lock member U is simply configured not to move in the direction of the end side vertical rib 1g. Yes.

  Next, as shown in FIG. 2, the order of assembling the box pallet Bp in a folded state into a box shape as shown in FIG. 1 will be mainly described with reference to FIGS. 35 and 36. explain.

  First, the rearward inclined side wall 2 in the substantially horizontal state is set up substantially vertically, and then the preceding inclined side wall 1 in the substantially horizontal state is rotated in the vertical direction. In this way, in a state where the preceding inclined side wall 1 is set to be substantially vertical after the trailing inclined side wall 2, as shown in FIG. 36, the abutting frame 2e of the trailing inclined side wall 2 is preliminarily inclined. The vertical elongated strip 1e of the side wall 1 abuts or approaches the vertical strip 1e1 of the preceding tilted side wall 1 and the fitting ridge 1e1 projecting from the vertical tilted side wall 1e of the preceding tilted side wall 1 contacts the abutting frame 2e of the trailing tilted side wall 2. It will be inserted into the drilled fitting hole 2e1. In this way, the assembling operation into the box shape in which the rearwardly inclined side wall 2 in the substantially horizontal state is set up substantially vertically and then the preceding inclined side wall 1 in the substantially horizontal state is set up substantially vertically, is formed on the preceding inclined side wall 1. The lock member U attached in the arrangement space A is in the release position. That is, the tip u2a of the lock portion u2 of the lock member U does not protrude outward beyond the end vertical rib 1f.

  Next, when the lock member U is moved in the direction of the reinforcing block 1j and the end vertical rib 1f, the tip u2a of the lock portion u2 of the lock member U protrudes beyond the end vertical rib 1f, and the lock member U The lock portion u2 is inserted into the lock portion insertion recess 2e3 formed in the abutting frame 2e of the trailing inclined side wall 2, and the locking protrusion u4a of the elastic tongue piece u4 constituting the lock member U is provided as a reinforcing block. 1j and the engaging vertical recess 1k5 formed in the outer vertical inner surface 1k2 of the lock insertion hole 1k formed in the end vertical rib 1f. In this way, the locking projection u4a of the elastic tongue u4 constituting the lock member U is formed on the outer side vertical inner surface 1k2 of the lock portion insertion through hole 1k formed on the reinforcing block 1j and the end vertical rib 1f. Since the locking recess U is configured to be engaged with the locking recess 1k5, the locking member U is provided with the locking portion u2 of the locking member U formed on the abutting frame 2e of the trailing tilt side wall 2. Even if an external force that is discharged from the recess 2e3 is applied, the lock portion u2 of the lock member U is easily discharged from the lock portion insertion recess 2e3 formed in the contact frame 2e of the trailing tilt side wall 2. This can be prevented. Further, in this state, even if a load is applied to the preceding inclined side wall 1 from the outside, the lock portion u2 of the lock member U attached in the arrangement space A formed in the preceding inclined side wall 1 is 2 is inserted in the lock portion insertion recess 2e3 formed in the second contact frame 2e, the pre-tilt side wall 1 is not rotated in the upper surface direction of the upper deck p1 of the pallet portion P.

  Next, in order to fold the box pallet Bp assembled in a box shape as shown in FIG. 1 as shown in FIG. 2, the lock member U is moved to the end side vertical rib. The lock portion u2 of the lock member U is moved in the 1g direction to be discharged from the lock portion insertion recess 2e3 formed in the contact frame 2e of the trailing tilt side wall 2, and then the leading tilt side wall 1 is moved to the upper deck. Rotate in the upper surface direction of p1 to fall to a substantially horizontal state, and then turn the trailing tilt side wall 2 to the upper surface direction of the upper deck p1 to the preceding tilted side wall 1 that has been tilted to a substantially horizontal state. By tilting so as to overlap, the box pallet Bp is folded into a compact state with a low height. When a predetermined force is applied to the lock member U and the lock member U is moved in the direction of the end-side vertical rib 1g, the locking protrusion u4a of the elastic tongue u4 constituting the lock member U is brought into contact with the elastic tongue u4. Against the elastic force, it is discharged from the locking recess 1k5 formed in the outer vertical inner surface 1k2 of the lock insertion hole 1k formed in the reinforcing block 1j and the end vertical rib 1f, and as described above The lock member U can be moved in the direction of the end-side vertical rib 1g.

  As described above, the plate-like portion 1a located in the arrangement space A of the pre-tilt side wall 1 has an upper fitting hole 1n and a lower fitting hole formed in the back plate 1m1 constituting the fitting recess 1m. Except for 1p, no through hole is drilled, and when the abutting member E is installed in the arrangement space A, the upper blind block e2 of the abutting member E is fitted. The lower blind block e3 of the abutting member E is fitted into the lower plate 1m1 of the fitting recess 1m and is fitted into the upper fitting hole 1n drilled in the rear plate 1m1 of the fitting recess 1m. The upper fitting hole 1n and the lower fitting hole 1p inserted into the hole 1p and formed in the back plate 1m1 of the fitting recess 1m are closed by the upper blind block e2 and the lower blind block e3 of the abutting member E. It will be stored in the box part B of the box pallet Bp assembled in a box shape. It can be partially or fine articles of the article, to prevent such enters the disposing space A. Therefore, it is possible to prevent the smooth movement of the lock member U arranged in the arrangement space A from being blocked by the article that has entered the arrangement space A.

  In addition, as described above, by forming the substantially U-shaped slit s2 in the plate-like body e1 of the abutting member E, the arrangement of the leading inclined side wall 1 is provided instead of forming the contact elastic tongue piece e6. The present applicant's earlier application is to form an abutting elastic tongue piece by directly forming a substantially U-shaped slit in the plate-like portion 1a located in the installation space A. Proposed in Japanese Patent Application No. 2005-122126, when such a substantially U-shaped slit is directly formed in the plate-like part, it is accommodated in the box part of the box pallet assembled in a box shape. Some of the articles and fine articles that have been placed enter the arrangement space from the substantially U-shaped slit, and the smooth movement of the lock member arranged in the arrangement space is prevented. However, according to the present embodiment, the above-described configuration causes a disposition space. The intruding article in A, it is possible to prevent such smooth movement of the locking member U being disposed within disposing space A is prevented.

  Furthermore, when the contact elastic tongue piece is formed by forming a substantially U-shaped slit directly in the plate-like portion located in the space where the preceding inclined side wall is disposed, the contact elastic tongue There is a case where an article accommodated in a box part of a box pallet assembled in a box shape comes into contact with the piece and the contact elastic tongue piece is damaged. Thus, if the abutting elastic tongue is broken, the pre-tilt side wall must be replaced or the entire box pallet must be discarded. However, in this embodiment, it is only necessary to replace the abutting member E on which the contact elastic tongue e6 is formed, which is separate from the lock member U. Cost reduction can be realized compared to the case where the entire pallet has to be discarded.

  When the box pallet Bp is assembled into a box shape, the virtual vertical outer wall surface F2 of the trailing inclined side wall 2 formed by the tip of the upper horizontal rib 2b, the tip of the lower horizontal rib 2c, etc. The virtual vertical outer wall surface F1 of the vertical wall member 8 formed by the front end and the front end of the vertical rib 8d is substantially flush with the virtual vertical outer wall surface F2 of the trailing inclined side wall 2 and the virtual wall surface of the vertical wall member 8. The vertical outer wall surface F1 is formed by retracting a predetermined amount (denoted by D1 in FIG. 9) from the outer vertical wall 3b1 forming the other facing bank portion 3b ″ of the frame-shaped bank member 3b. Therefore, even if the trailing inclined side wall 2 bulges outward due to the weight of the article stored in the box pallet Bp, the trailing inclined side wall 2 is not attached to the other side of the frame-shaped bank member 3b. Bank part 3b Beyond the outer vertical walls 3b1 which form a, it is not such as to protrude outward. Therefore, the backward inclined side wall 2 weak in strength compared to the frame-shaped bank member 3b of the pallet portion P abuts on the box pallet Bp or other object assembled in another box shape, and the subsequent inclined side wall 2 Can be prevented from being damaged.

  Further, even if the trailing tilt side wall 2 bulges outward, the trailing tilt side wall 2 exceeds the outer vertical wall 3b1 that forms the other facing bank portion 3b '' of the frame-shaped bank member 3b, Since the box pallets Bp assembled in a box shape are arranged side by side so that the trailing inclined side walls 2 face each other, the pallet portions P of the adjacent box pallets Bp are in contact with each other. Boxes that are in contact with each other and do not come into contact with each other on the outside of the rearwardly inclined side wall 2, so that no gap is formed between adjacent box pallets Bp, and the box is assembled in a box shape. The accommodation efficiency of the pallet Bp is improved.

  Similarly, as shown in FIG. 10, when the box pallet Bp is assembled into a box shape, the leading inclined side wall 1 formed by the tip of the upper horizontal rib 1b, the tip of the lower horizontal rib 1c, etc. The virtual vertical outer wall surface F3 is formed by being retracted by a predetermined amount D2 from the outer vertical wall 3b1 forming the leading inclined side wall bank portion 3b ′ of the frame-shaped bank member 3b constituting the upper deck 3. Therefore, even if the pre-tilt side wall 1 bulges outward due to the weight of the article stored in the box pallet Bp, the pre-tilt side wall 1 can be used as the pre-tilt side wall bank portion 3b ′ of the frame-shaped bank member 3b. Since it does not protrude outward beyond the outer vertical wall 3b1 to be formed, the leading inclined side wall 1 that is weaker in strength than the frame-like bank member 3b of the pallet part P is assembled into another box shape. It is possible to prevent the pre-tilt side wall 1 from being damaged by coming into contact with the box pallet Bp and other objects.

  Even if the pre-tilt side wall 1 bulges outward, the pre-tilt side wall 1 protrudes beyond the outer vertical wall 3b1 that forms the bank portion 3b 'for the pre-tilt side wall of the frame-shaped bank member 3b. Therefore, when the box pallets Bp assembled in a box shape are arranged side by side so that the preceding inclined side walls 1 face each other, the pallet portions P of the adjacent box pallets Bp come into contact with each other, and the leading inclination Since the parts bulging to the outside of the side wall 1 do not come into contact with each other, therefore, no gap is formed between adjacent box pallets Bp, and the housing efficiency of the box pallet Bp assembled in a box shape is reduced. Will improve.

  Furthermore, as shown in FIG. 10, the inclined surface 3b2 ′ formed at the outer corner formed by the outer vertical wall 3b1 and the horizontal top plate 3b2 of the other opposite bank portion 3b ″ is shown in FIG. As described above, it is preferable to form the inclined surface 3b2 ″ at the outer corner formed by the outer vertical wall 3b1 and the horizontal top plate 3b2 of the bank portion 3b ′ for the previously inclined side wall. By forming such an inclined surface 3b2 ″, dust and the like accumulated on the horizontal top 3b2 can be reduced as compared with the case where the entire horizontal top 3b2 is formed as a horizontal plane.

  When the fork is inserted into the fork insertion port 7 formed on the side of the pallet part P located on the side of the bank part 3b ′ for the pre-tilt side wall of the frame-shaped bank member 3b, the tip of the fork is moved to the pallet part P. Of the female hinge recess H1 formed in the leading tilt side wall bank portion 3b 'constituting the hinge connecting portion between the leading tilt side wall bank portion 3b' of the frame-shaped bank member 3b and the leading tilt side wall 1 The slit h4 and the short axis h1b ′ of the male hinge member H1 ′ disposed on the preceding inclined side wall 1 may abut against the vicinity of the outer vertical wall 3b1 of the leading inclined side wall bank portion 3b ′. The hinge connecting portion between the inclined side wall bank portion 3b ′ and the preceding inclined side wall 1 is not disposed directly on the outer vertical wall 3b1, but is disposed at a position separated from the outer vertical wall 3b1. The tip of the fork Even if it comes into contact with the outer vertical wall 3b1 of the bank portion 3b 'for the pre-tilt side wall located near the connecting portion, the impact caused by the contact of the tip of the fork with the outer vertical wall 3b1 is directly applied to the pre-tilt side wall. There is no transmission to the hinge connecting portion between the bank portion 3b 'and the pre-tilt side wall 1. Accordingly, the vertical slit h4 of the female hinge recess H1 formed in the bank wall portion 3b ′ for the pre-tilt side wall of the frame-shaped bank member 3b constituting the pallet portion P, and the pre-tilt side wall 1 inserted in the vertical slit h4. It is possible to prevent the hinge connecting portion constituted by the short axis h1b ′ of the male hinge member H1 ′ disposed on the damaging member from being damaged.

  38 and 39 show a lid member G that is covered by a box pallet Bp assembled in a box shape or a folded box pallet Bp. The lid member G has a top plate portion g1 and a peripheral wall portion g2 extending downward from the periphery of the top plate portion g1. A circumferential bank portion g1a is formed on the outer peripheral portion of the top plate portion g1, and a central portion of one opposing bank portion g1a ′ forming the circumferential bank portion g1a is connected by a bridging bank portion g3. ing.

A fitting base g4 having a shape is formed. Further, a fitting block g4c that is substantially orthogonal to the longitudinal direction of one opposing bank portion g1a 'is suspended from the lower surface of the top plate g4a of the fitting base g4.

  As shown in FIG. 2, when the lid member G is covered with the folded box pallet Bp, the upper horizontal rib 8b of the vertical wall member 8 as shown in FIG. The substantially trapezoidal fitting block 9 formed on the upper surface of the central portion of the lid member G is fitted to the substantially trapezoidal fitting base g4 that is open on the lower side, and the fitting base g4. The fitting block g4c suspended from the lower surface of the top plate g4a is inserted into the fitting groove 9c formed in the horizontal upper surface 9b of the fitting block 9. By comprising in this way, the horizontal movement of the cover member G covered by the box pallet Bp of the folded state can be suppressed.

  Since the fitting block g4c is suspended from the lower surface of the top plate g4a of the fitting base g4 formed on the lid member G, the fitting base g4 of the lid member G placed on the floor or the like. In addition, even when a load is applied from above, the fitting base g4 can be prevented from being damaged.

  In addition, the fitting protrusion 2i can be suspended from the back surface of the lower end horizontal rib 2c of the trailing inclined side wall 2 as necessary. Thus, the fitting protrusion 2i suspended from the back surface of the lower end horizontal rib 2c of the trailing inclined side wall 2 is the other side of the frame-shaped bank member 3b when the box pallet Bp is assembled into a box shape. It is configured to be fitted into a fitting recess 8b1 formed in the upper end horizontal rib 8b of the vertical wall member 8 erected on the horizontal top plate 3b2 of the opposite bank portion 3b ″.
