Japanese Patent Laying-Open No. 2005-47575 (drawing)

  The conventional box pallet is not particularly functionally defective, but it is desired to improve the following problems.

  First, since the box pallet is transported by a forklift or a vehicle, it has not been completely devised to be lifted or hung by a crane at a construction site.

  Therefore, when lifting with a forklift, other special measures must be taken each time, and the wire tip hook of the forklift is hooked on the wire mesh forming the panel, and the panel may be damaged.

  Secondly, it is assembled into a box shape at the time of use, but in order to maintain this box shape, a firm locking mechanism is necessary, but the means is not necessarily sufficient, and the box state cannot be maintained, and in some cases May be deformed.

  Thirdly, the area of the mesh of the wire mesh forming the panel is large, and there is a possibility that the internal contents fall from this mesh.

  Therefore, the object of the present invention is to transport not only forklifts but also cranes, and can reliably hold the shape when assembled in a box shape, even with small parts by making the mesh of the metal mesh forming the panel as small as possible. It is to provide a foldable box pallet that can prevent falling.

In order to achieve the above object, the means of the present invention comprises a floor panel 1, a stacking leg 2 erected at the four corners of the floor panel 1, and a pair of left and right front and rear legs 2, 2. A two-fold left panel 3 that is freely pivoted, a two-fold right panel 4 that is also pivotably supported between a pair of right and left front and rear legs 2, and a pair of front left and right legs. The front panel 5 is rotatably supported between the bodies 2 and 2, and the rear panel 6 is also rotatably supported between the rear left and right pair of legs 2 and 2. In the box pallet in which the front panel 5 and the rear panel 6 are overlapped and folded on the left and right panels 3 and 4 in the box pallet, the left and right panels 3 and 4 or the front and rear panels 5 and 6 are folded. Attach a hanging bracket 7 to be hung on the crane wire at any of the top of the Further, when the left and right panels 3 and 4 and the front and rear panels 5 and 6 are erected into a box shape, the first and second locking mechanisms A and B that maintain the box state are connected to the left and right panels 3 and 4 and the front and rear panels 5 and 6. And a cap 8 that fits the first locking mechanism A on both end portions of the left and right panels 3 and 4 so as to be movable up and down, and is integrally coupled to the cap 8 to form the left and right panels 3 and 4. The second locking mechanism B is provided on the front and rear piles 5 and 6 so as to be detachably inserted into the upper end portions of the front and rear panels 5 and 6, and the hinge portion 10 at the center of the left and right panels 3 and 4 is provided. It is characterized by comprising a rotatable lock pin 12 facing the shaft 11 in FIG.

  In this case, the pivot point of the rear panel 6 is shifted upward from the pivot point of the front panel 5 with respect to the leg 2 by the same dimension as the thickness of the front panel 5.

  Similarly, a socket 13 is integrally provided at the lower end of the leg 2, and the front and rear panels 5, 6 are a pair of left and right frames 14, 14, a pair of upper and lower frames 15, 16, and each frame 14, 14, 15, It is preferable that the upper end portions 14 a and 14 a of the left and right frame bodies 14 and 14 are erected above the upper frame body 15.

  According to the present invention, the following effects can be obtained.

  1) Since the left and right panels and the front and rear panels can be folded, the whole can be folded compactly when not in use, and a large number of box pallets can be transported and stored at once.

  2) Since hanging brackets are attached to the upper part of the left and right panels or the front and rear panels, a wire can be hooked on the hanging brackets via hooks and the box pallet can be transferred to a predetermined place by a crane. At this time, since the hook is not hooked on the wire mesh panel, it is possible to prevent the panel from being damaged.

  3) When the left and right panels and the front and rear panels are erected and assembled into a box shape, the box pallet itself is in use because the box state is maintained by the first locking mechanism provided between the left and right panels and the front and rear panels. Can be prevented from being deformed or folded.

  4) Since the heights of the pivot points of the front panel and the rear panel are different, the front and rear panels can be sequentially stacked on the folded front panel.

  5) Since the first lock mechanism is composed of a cap and a lock pin, the lock pin can be prevented from being loosened, rotated and loosened by fitting the cap to the upper part of the front and rear panels.

  6) Since the second lock mechanism is provided to face the hinge portions of the left and right panels, the left and right panels can be prevented from being bent and the box state can be maintained.

  7) Since the legs are provided with sockets and the upper ends of the left and right frames are raised upward, the upper box pallet socket is fitted to the upper end of the frame of the lower box pallet so that the vertical direction Multi-tiered box pallets can be stacked without slacking along

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 9, the box pallet of the present invention includes a rectangular floor panel 1, a stacking leg 2 erected at the four corners of the floor panel 1, and the left and right legs 2, 2. A two-fold left panel 3 pivotally supported via a lower shaft 26, and two folds pivotally supported via a shaft 26 between a pair of right and left legs 2 and 2 in the same manner. A right panel 4 of the type, a front panel 5 rotatably supported between a pair of front left and right legs 2, 2 via a lower shaft 27, and a pair of rear left and right legs 2, 2 And a rear panel 6 that is rotatably supported via a lower shaft 28.

  Then, the left and right panels 3 and 4 are folded inward via the central hinge 10 and further folded over the floor panel 1 while being rotated via the shafts 26 and 26. The panel 5 and the rear panel 6 are rotated through shafts 27 and 28 and folded while being overlapped.

  Further, the box pallet of the present invention is provided with a hook fitting 7 for hook hooking that is hung on a wire of a crane on any or all of the upper part of the left and right panels or the front and rear panels 5 and 6.

  The left and right panels 3 and 4 and the front and rear panels 5 and 6 are formed in a box shape whose upper part is opened when standing up. At this time, the first lock mechanism A and the first lock mechanism A are arranged so as to maintain the box state and prevent deformation. Two locking mechanisms B (see FIG. 7) are provided between the left and right panels 3 and 4 and the front and rear panels 5 and 6.

  Each leg 2 is formed of an angle member having an L-shaped cross section, and a trumpet type socket 13 is integrally provided at the lower part of each leg 2.

  As shown in FIGS. 1 and 9, the floor panel 1 includes a rectangular frame body 19 and a floor made of a wire mesh 20 laid vertically and horizontally between the frame bodies 19, and a corner of each frame body 19 is a leg 2. It is fixed inside the angle material.

  Similarly, as shown in FIGS. 3 and 9, the front and rear panels 5 and 6 are fixed inside the pair of left and right frames 14 and 14, the pair of upper and lower frames 15 and 16, and the frames 14, 15 and 16. The upper end portions 14a and 14a of the left and right frame bodies 14 and 14 are erected above the upper frame body 15.

  This upper end portion 14a stands upward when a plurality of box pallets are stacked upward and the socket 13 in the leg 2 of the upper box panel is fitted into the frame upper end portion 14a of the lower box pallet. The upper and lower box panels can be prevented from loosening.

  The wire mesh of the floor panel 1, the left and right panels 3 and 4, and the front and rear panels 5 and 6 are assembled so that the length and width are 20 millimeters. Prevents falling. Therefore, it is preferable that this mesh is as fine as possible.

  The front and rear panels 5 and 6 are rotatably supported by lower shafts 27 and 28, but the position of one shaft 28 is set to a position higher than the position of the other shaft 27.

  That is, as will be described later, the left and right panels 3 and 4 are folded on the floor panel 1 and then the front panel 5 is folded on the left and right panels 3 and 4. The height of the shaft 27 is set at a position larger than the total thickness of the left and right panels 3 and 4, and the height of the shaft 28 of the rear panel 6 is set at a position larger than the total thickness of the left and right panels 3 and 4 and the front panel 5. Is set.

  In other words, the position of the shaft 28 is positioned above the thickness of the front panel 5, so that the leg 28 is located below the frame 16 below the front and rear panels 5, 6 as shown in FIGS. 3 and 9. A fixed panel 29 fixed between the bodies 2 and 2 is provided to prevent a space from being formed below the shafts 27 and 28.

  As shown in FIGS. 2, 5 and 9, the left and right panels 3 and 4 are formed by connecting two panels each having a rectangular frame and a wire mesh installed in the frame at a central hinge 10. It is made up of.

  Therefore, the entire left and right panels 3 and 4 are composed of the upper frame body 30, the left and right frame bodies 31, the shaft 26 provided on the lower frame body, and the wire mesh extended between these frame bodies 30 and 31. Thus, the whole is rotated about the lower shaft 26 as a fulcrum, and can be folded on the floor panel 1 by being bent inward by the hinge 10 at the center.

  Next, as shown in FIG. 6, the first lock mechanism A includes a cap 8 having a U-shaped cross section, a U-shaped lock pin 9 which is inserted and fixed in the center of the cap 8, and a lock pin 9. It comprises a stopper 9c made of a nut provided at the base end of the main body 9a, and the main body 9a is inserted into holes formed in the upper frame body 30 of the left and right panels 3 and 4 so as to be movable in the vertical and rotational directions. 9 is inserted into a hole in the upper frame 15 of the front and rear panels 5 and 6. For this reason, when the left and right panels 3 and 4 and the front and rear panels 5 and 6 are assembled in a box shape, the lock pin 9 is installed between the left and right panels 3 and 4 and the front and rear panels 5 and 6 and maintained in a box shape. is there.

  At this time, the cap 8 is fitted into the frame body 30 to prevent the lock pin 9 from rotating or loosening.

  When the left and right panels 3 and 4 are folded from the box state, the lock pin 9 and the cap 8 are pulled up, the tip 9b is pulled out from the hole, the stopper 9c is hooked on the lower surface of the frame 30, and the tip 9b of the lock pin 9 is Rotate and insert into another hole 15a.

  Thereby, the connection between the left and right panels 3 and 4 and the front and rear panels 5 and 6 is canceled, and each panel can be rotated and folded.

  The lock pin 9 may be attached to the front and rear panels 5 and 6 so as to be movable up and down, contrary to the above.

  Next, the second lock mechanism B will be described with reference to FIG.

  The lock mechanism B is composed of L-shaped lock pins 12 which are provided on the left and right panels 14 of the front and rear panels 5 and 6 so as to be opposed to the hinge portion 10 and to be rotatable.

  The lock pin 12 has a base end rotatably supported by a shaft 12a and rotates downward by its own weight so that the pin main body faces the shaft 11 of the hinge portion 10 and restricts the hinge portion 10 from being bent.

  On the other hand, when the left and right panels 3 and 4 are bent at the hinge portion 10, the lock pin 12 is rotated upward with a finger, then brought into contact with the inner wall of the frame body 14 by its own weight and brought into contact with the inner wall of the frame body 14 by its own weight. So that it does not move downward.

  Next, a box pallet folding method will be described with reference to FIG.

  First, as shown in FIG. 6, the lock pin 9 in the first lock mechanism A is pulled up, and the tip 9 b is removed from the holes of the front and rear panels 5, 6, and between the left and right panels 3, 4 and the front and rear panels 5, 6. Release the bond.

  At the same time, as shown in FIG. 7B, the lock pin 12 in the second lock mechanism B is pushed upward while rotating through the shaft 12a from the solid line position to the dotted line position, and the lock pin for the shaft 11 in the hinge portion 10 12 is eliminated, and the left and right panels 3 and 4 can be bent inward via the hinge 10.

In this state, as shown in FIGS. 10A and 10B, the left and right panels 3 and 4 are sequentially bent and rotated inward via the shaft 26, and then, as shown in FIG. , 4 are folded over the floor panel 1 to meet each other.
Next, as shown in FIG. 11 (D), the front panel 5 is rotated through the shaft 27 so as to be superimposed on the left and right panels 3 and 4, and further, as shown in FIG. Then, the rear panel 6 is rotated and overlapped on the front panel 5, and the whole is folded or compactly stored and transported as it is.

  By the way, the box pallet of this invention can be conveyed to a predetermined place, inserting the fork of a forklift into the lower part of the floor pallet 1 and raising it.

  On the other hand, as shown in FIG. 8 (A), the wire W hung on the crane is hooked on the hanging bracket 7 of a single box pallet and is transferred to a predetermined position while being lifted.

  Also, as shown in FIGS. 8B and 8C, when the box pallets stacked in two stages are transported at once by a crane, the leg 2 and the upper end portion 14a of the frame 14 are fitted together. Then, the wire W is hooked on the hanging bracket 7 of the lower box pallet.
