[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention has a base portion formed in a substantially rectangular flat shape for mounting a long object, and a column body for preventing the long object from falling is provided in a constant planar positional relationship on the left and right sides of the base portion. The present invention relates to a long object carrier having a structure in which at least four of them are erected upright and the upper end of the lower pillar is fitted to the lower end of the upper pillar when vertically stacked in use.

[0002]

[Prior art]

 For example, a conventional long cargo bed that conveys a long object such as an aluminum mold material or a vinyl chloride round pipe has the structure as described above, and may be used or not used. Instead, they can be stacked on top of each other due to the fitting structure of the columns. Therefore, even when collecting an empty long carrier from a customer or each factory, the volume occupied by the same carrier is the same as when there is a load, and the number of long carriers that can be loaded on one truck is also large. It is immutable.

[0003] Therefore, an attempt has been made to combine the upper empty carrier with the lower one by turning it upside down, and hold the two lower carriers to a height of about one unit to increase the number of items to be loaded. However, in order to do so, it is necessary to turn each upper long cargo bed upside down and turn it upside down. In order to stack long objects, it is necessary to restore the normal posture. There is a drawback that This type of long cargo bed has a long cargo bed of, for example, 4500 to 6000 mm, and therefore the freight required for recovery by a truck is enormous, and in addition, a large storage yard is required for the empty cargo bed. .

[0004]

[Problems to be solved by the device]

 The present invention has been made by paying attention to the above points, and the problem is that it does not require special work such as turning upside down or upside down, and it can load a large number of empty loading platforms densely. The goal is to significantly reduce the recovery costs for empty pallets and to make efficient use of the empty yard storage yard.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is designed to displace the column bodies 21 of the lower loading platform and the column bodies 21 of the upper loading platform in the front and rear directions when the columns are stacked in the unused state. A procedure of installing on the outer surface of the part 10 while maintaining the above-mentioned positional relationship, connecting the column bodies 21 on the left and right sides, and attaching a frame body 22 connecting both ends to the base part 10 to the outer surface of each column body 21. Was taken.

Each of the long object carrier A has at least four pillars 21 standing upright in a fixed planar positional relationship, and the upper and lower ends of each pillar 21 are mutually connected. Since the structure for fitting is provided, the lower end of the column body 21 of the upper loading platform is fitted to the upper end of the column body 21 of the lower loading platform in the use state (see FIGS. 7 and 8). Therefore, it is possible to place a long object on each cargo bed A, use it as a cargo bed, and stack it vertically as it is.

Each columnar body 21 is installed on the outer surface of the pedestal 10 while maintaining a constant planar positional relationship, and the frame body 22 connecting each columnar body 21 also includes the frame body 22 of each columnar body 21. Since it is attached to the outer side surface, when stacking the upper cargo bed A while avoiding the pillars 21 of the lower cargo bed A during vertical stacking (shifting forward and backward in the longitudinal direction of the cargo bed), the lower end of the upper cargo bed A (24 ) Can come into contact with the upper surface of the base 10 of the lower bed (see FIGS. 9 and 10). Therefore, the upper and lower pedestals 10 and the pedestal 10 are very close to each other when not in use when there is no load (long object) on each pedestal A, so many empty pedestals A should be stacked closely. You can

[Embodiment of device]

 The long object carrier A according to the present invention has a base portion 10 formed in a substantially rectangular plane shape for placing and stacking long objects, and the long objects placed on the base portion 10 do not fall. Thus, at least four pillars 21 are provided upright on the left and right of the base 10. The column body 21 is erected in a fixed planar positional relationship in order to vertically stack the loading platform A of the present invention. A fitting structure 30 is provided at the upper end of the upper column so that the lower end of the upper column fits therein.

The table portion 10 in the present invention is intended to mount a long object as described above. Therefore, the necessary conditions are that the long object to be loaded does not protrude too much and is not deformed or damaged. Since it is supported without being raised, the form may be plate-like or ladder-like. The base 10 according to the illustrated embodiment has a trapezoidal structure in which vertical parallels 12 and 13 are provided between two parallel horizontal parallels 11 and 11 and at both ends. Each of the vertical shafts 12 and 13 intersects the horizontal shaft 11 at a right angle.

Further, the pillar body 21 in the present invention is intended to prevent the long objects placed on the platform 10 from falling and to stack the loading platforms A vertically, and the necessary conditions therefor are predetermined. It has a high height and can withstand the load applied during stacking. Therefore, at least two pillars 21 are required on each of the left and right sides of the base 10, and a total of four pillars 21 are required. The pillar body 21 according to the illustrated embodiment has a leg portion 23 whose lower end projects downward from the base portion 10 and separates the base portion 10 from the surface of a storage yard or the like.

The column bodies 21, 21 on the left and right sides are connected to each other by the frame bodies 22 on the left and right sides in the loading platform longitudinal direction, and both ends of each frame body 22 are coupled to the end portions of the platform 10. The column body 21 and the frame body 22 are integrally combined to form a handrail-shaped side frame 20 (FIG. 2). The side frame 20 in the illustrated embodiment is provided with stays 26 and 27 that connect the frame body 22 and the base 10 and transmit the load to the base 10. Some stays 26 are provided at the upper end so as to transmit the load applied to the hanging hand 25 for suspending the whole, and the other stays 27 reinforce the frame body 22 to which the receiving plate 28 for the forklift is attached. There is.

What is particularly important here is that each column 21 is erected on the outer surface 19 of the base 10 (FIG. 4), and also the frame 22 is attached to the outer surface 18 of the column 21. is there . As a result, there is no obstruction on the upper surface of the pedestal portion 10, and it is possible to stack the pedestal portions 10 on top of each other by bringing the pedestal portions 10 into contact with each other by moving the columns 21 forward and backward. In the illustrated embodiment, the small legs 24 are provided on the lower side of the base 10, so that the upper base 10 is separated from the lower base 10 by the amount of the protrusion.

In the illustrated embodiment, the column body 21 is welded to the outer surface 19 of the base portion 10, and the frame body 22 is welded to the outer surface 18 of the column body 21. Inclined portions 22a are provided on both ends of the frame body 22, and L-shaped tip portions 22b thereof are connected to the base portion 10.

The fitting structure 30 according to the present invention is provided to prevent the upper and lower pillars 21 from slipping when vertically stacked, and includes a protrusion 31 and a recess 32 that can be fitted to each other. In the illustrated embodiment, the protrusion 31 projects upward from the upper end of the column 21 (see FIG. 6B), and the recess 32 is a portion opened to the lower end of the column 21. In the illustrated concave portion 32, the opening at the lower end cut end of the square pipe-shaped columnar body 21 is used almost as it is. In the figure, numeral 35 is a protective member made of hard rubber or the like, which is attached to the inner side surface of the column body 21 and the upper surfaces of the vertical bars 12, 13 to protect the contact surface of the long object. Similar protection members are also provided on the stays 26 and 27.

FIGS. 7 and 8 show the long object loading platform A of the present invention having the above-described structure and are vertically stacked in a used state. The upper and lower cargo beds A are supported by the pillars 21 and 21, and are stably stacked by the upper and lower fitting structures 30. Therefore, a predetermined amount of long objects can be loaded on each of the stacked loading platforms A. Alternatively, on the contrary, the loading platform A on which the long objects are loaded can be vertically stacked as shown in FIG. At this time, the backing plate 28 is used for carrying the loading platform A by a forklift.

The stack in the unused state is shown in FIGS. 9 and 10. The second-stage loading platform A is stacked on the bottom-stage long loading platform A with the frame body 21 of the lower-level loading platform A shifted longitudinally in the longitudinal direction from the column body 21 of the lower loading platform A. Stack up to the 3rd and 4th steps. On the upper surface of each base portion 10, small legs 24 projecting from the inner lower surface of the upper cargo bed A are placed. After stacking about 4 steps, the columns 21 of the 5th stage are returned to the positions of the columns 21 of the lowermost loading platform A, and are similarly shifted in the longitudinal direction by the thickness of the columns 21. In the case of this example, the 4-tier stack requires only the height of the conventional 2-tier, and therefore the stack weight is increased at least twice as much as the conventional one.
