Description

  The present invention is a folding pallet for carrying goods, that is, a pallet floor frame having a net-like or plate-like four-sided side plate portion that can be folded on the floor frame, and a plurality of pallets arranged vertically. The present invention relates to a folding pallet configured to be stacked in a direction.

  Conventionally, the floor plate portion of this kind of folding pallet is usually formed by assembling a vertical frame material and a horizontal frame material, which are straw materials, in a cross-beam shape. And the mutual intersection part was combined so that it might become the form which overlapped. (For example, refer to Patent Document 1.)

  Furthermore, the fork insertion part is formed in the floor part of the folding pallet by installing a so-called ski frame called a ski at the lower end of the front and rear columns of the pallet, and fork insertion between this and the floor board. A void was formed. (For example, see Patent Document 2.)

This type of folding pallet is kept in a folded state when not in use and stored in a state where a required number of the pallets are stacked, or in a relation of carrying out return transportation after use in such a stacked state. It would be desirable to occupy as little space as possible during storage or return shipping. Therefore, a configuration is required that is as thin as possible in the folded state.
In this case, a method of reducing the thickness of the four-sided side plate portion folded inward and a method of reducing the thickness of the pallet floor plate portion can be considered.

  In the case of the above-described method of reducing the thickness of the four-side plate part folded inward, the thinning inevitably leads to weakening of the four-side plate part, and the damage to the four-side plate part due to the swinging load of the package during transportation. In extreme cases, it is expected that there is a danger that the contents will jump out. Therefore, it is preferable to avoid such a system as much as possible.

  Although this is a method for reducing the thickness of the pallet floor plate part, if this is simply reduced, there is a risk based on strength deterioration as described above. In addition, the floor surface portion including the fork insertion portion of the pallet can be thinned without causing deterioration in strength.

  By the way, as mentioned above, when the floor surface portion is formed by overlapping the vertical beam and the horizontal beam, which are made of wood, and assembled in a cross beam shape, the crossing part of each other is a form in which the two beams overlap each other. This forces the overall thickness to increase. Then, in order to eliminate such a problem, it is possible to cut the vertical beam or the horizontal beam so as to be divided and to assemble them so as to be in the same plane and join them. However, in such a case, the complexity of manufacturing the floor surface portion, that is, the burden of work time required for cutting and joining, inevitably directly leads to an increase in cost. Furthermore, the presence of such a joint is also a factor that causes strength deterioration.

  In addition, the form of the insertion part of the fork formed on the floor plate part of the folding pallet is that a grounding frame rod called a so-called ski frame is installed at the lower end of the front and rear columns of the pallet, and the fork is placed between this and the floor plate. When forming the gap for insertion, the thickness of the grounding frame must be a certain thickness from the viewpoint of strength, and it has been impossible to simply reduce the thickness.

  The present invention aims to provide a new folding pallet configured so that the thickness of the floor plate portion of the folding pallet can be reduced without causing deterioration in strength by using a new member ridge. It is a thing.

The folding pallet according to the present invention is formed by attaching, on the upper surface of the pallet floor frame, four side plates B that can be folded on the floor frame, and a plurality of pallets can be stacked in the vertical direction. In the configured folding pallet,
The floor frame A has a form in which a reinforcing frame in which horizontal beams and vertical beams are assembled in a cross beam shape is installed in a rectangular outer frame, and the reinforcing frame is used as a forming material for the frame. A folded portion m is formed on the side surface by folding the both side portions into the required portion of the rectangular hollow tube having a predetermined length and lowering the upper surface side so as to match the lower surface side. Uses a brazing material formed with a thin portion M by compressing and flattening into a shape such as a flat surface,
The ribs are used as vertical and horizontal crosspieces, and their thin portions M are crossed in a state of being engaged with each other so that they are combined into the same plane cross beam.

In addition, the folding pallet according to the present invention has a four-sided side plate portion B that can be folded on the floor frame on the upper surface of the pallet floor frame, and can stack a plurality of pallets in the vertical direction. In the folding pallet configured as described above, as a configuration for inserting a fork provided on the lower surface side of the pallet floor frame, as a ski frame for symmetrically attaching to the required side surface,
A fold portion m is formed on the side surface by folding the both side portions into the required portion of the rectangular hollow tube having a predetermined length and lowering the upper surface side so as to match the lower surface side. Formed with a brazing material formed by forming the thin portion M by compression flattening into a shape such as a flat surface,
The thin portion M in the upward state described above is configured to be formed at two locations that coincide with the fork insertion portion.

The present invention is configured to achieve the purpose of thinning the floor plate portion of the folding pallet based on the above-described configuration.

  In addition, although it is an above-mentioned brazing material, the ex vivo-shaped parts n and n by gradually thinning are formed in the both ends of the folding part m formed by folding the front and back side surfaces inside. It is preferable to configure from the viewpoint of improving strength.

In the present invention, the floor frame A is constructed in the outer frame C in which the reinforcing frame D in which the cross beam 5 and the vertical beam 6 are assembled in a cross beam shape is assembled in a rectangular shape. The reinforcing frame D has a form, and the reinforcing frame D is formed into a required portion of a rectangular hollow tube having a predetermined length, and both side surface portions are folded inward and the upper surface side is directed to the lower surface side. The saddle material is formed by forming a thin portion M by compressing and flattening into a shape in which the folded portion m is formed on the side surface by being lowered so as to be matched and the bottom surface side is a flat surface. Is used as a vertical and horizontal crosspiece and the thin portions M of each other are crossed in a state of being engaged with each other so that they are combined into a coplanar well girder. It is done.

This is because, when the floor board part is formed by stacking the vertical frame material and horizontal frame material that are vertical and horizontal, as in the conventional case, that is, the crossing portions of each other are overlapped. However, according to the present invention, the intersecting portion is configured to intersect with the thin portions M engaged with each other, so that the thinning is performed. The objective is achieved. At the same time, since the thin portion M is formed by overlapping two plate members having an appearance such as four overlapping plate portions, a total of eight layers of plate members are stacked. Not only does this not cause strength deterioration, but rather strength and toughness are achieved.

  With the above thinning, when the pallet is not in use or in return shipping after use, the side plate portion B is folded on the floor frame A and folded in the vertical direction. At this time, the smaller the thickness of each pallet in its folded state, the more the number of stacks can be increased, which is advantageous for transportation means in which the height of containers is limited. However, in the present invention, since the thickness is reduced in the folded state as described above, extremely advantageous loading is achieved.

The present invention has the structure as described in claim 2, i.e., as a structure for inserting a fork provided on the lower surface side of the pallet floor frame, as a ski frame 7 to be symmetrically attached to a required side surface thereof, with a predetermined length. Folded portion m is formed on the side surface by folding both side portions inward and lowering the upper surface side so as to match the lower surface side, and the bottom surface side is a flat surface. The thin portion M formed in the above-mentioned upward state is formed at two positions that coincide with the fork insertion portion. Since it forms so that it may form, the thickness of the floor board part of a pallet can be decreased.
This is because the fork insertion gap formed is indicated by the dimension P shown in FIG. 4, which also includes the downward compression dimension of the thin portion M, and therefore the pallet floor frame A and the ski frame. Since the distance dimension R with respect to 7 can be set as small as the compression dimension of the thin portion M, the thinning is achieved.
And since this invention was comprised so that such a rectangular hollow tube material might be used as a ski frame, when the problem on the intensity | strength which arose when the mere thin ski frame was formed like before is solved. At the same time, the problem of wall thickness that occurs when a simple straight rectangular hollow tube is used is avoided based on the presence of the thin portion M.

  The present invention has the structure described in claim 3, that is, the end portions n and n of the recessed portions m formed by folding the front and rear side surfaces inward are gradually thinned. Is formed on both side surfaces, and the presence of the exotic portions n and n makes it possible to strengthen the crossover thin portion M.

  1 to 4, A is a pallet floor frame, and a side plate portion B that is undulated and attached to the four circumferential surfaces of the pallet floor frame is configured to be folded in a superposed state on the upper surface of the floor frame A. It is. By the way, in the example of illustration, the said side-plate part B shall be a net-plate-like thing, the said side-plate part B is connected detachably with respect to the column S which stands upright at the four corners freely, Although the side plate part B is configured to be flattened in a state where it is stacked on the floor frame A by tilting the column S, in the present invention, such a constituent part is a main part. It is not a thing. Further, the configuration of the side plate portion B may be, for example, a plate-like side plate other than the net-like side plate as illustrated.

  In other words, the foldable configuration as described above belongs to the publicly known technology, and the feature of the present invention is that the configuration of the floor frame A portion has the following form to reduce the strength. It is that it was comprised so that remarkable flattening of the thickness in a folded state could be achieved without accompanying. In other words, the present invention is configured by attaching a side plate portion B of four circumferences that can be brought down on the floor frame to the upper surface of the pallet floor frame, and configured to stack a plurality of pallets in the vertical direction. The folded pallet is characterized in that the form of the floor frame A portion is configured as follows.

  Therefore, in this invention, the structure of the side-plate part B and the structure for the folding are based on the existing technique, and are not limited to the thing of illustration.

  Hereinafter, the configuration of the above-described floor frame A portion will be described in detail.

  As shown in FIG. 3, the floor frame A forms a rectangular frame-shaped outer frame C by assembling the left and right side rods 1, 2 and the front and rear side rods 3, 4 into a rectangular shape. The reinforcing frame D in which the horizontal beam 5 and the vertical beam 6 are assembled in the form of a cross beam is constructed.

  And it is a saddle material for forming the horizontal crosspiece 5 and the vertical crosspiece 6 of the above-mentioned reinforcement frame C, This has a structure as shown in FIGS. That is, as shown in the figure, the forming saddle material is lowered so that both side portions are folded inward and the upper surface side is matched with the lower surface side at a required portion of a rectangular hollow tube having a predetermined length. Thus, the thin portion M is formed by compressing and flattening into a shape in which the folded portion m is formed on the side surface and the bottom surface side is a flat surface.

  It should be noted that, as described above, a flat shape in which the extrudate portions n and n are formed at both end portions of the folded portion m formed by folding the front and rear side surfaces inward and the thickness thereof is gradually reduced. By adopting the above, the toughening of the thin portion M is achieved based on the existence of the exotic portions n and n.

  1 and 4 show fork insertion components formed on the pallet floor.

  In the figure, reference numeral 7 denotes a grounding ski frame, which is constructed in such a manner that leg rods 8 projecting from the bottom corners of the pallet floor frame A are connected to the front and rear portions of the pallet floor frame A. The ski frame 7 plays a role of ensuring stability when the pallet is placed on a roller conveyor.

The ski frame 7 has the above-described configuration, that is, a required part of a rectangular hollow tube having a predetermined length, and both side portions are folded inward and the upper surface side is set to the lower surface side. The thin portion M is formed by compressing and flattening into a shape in which the folded portion m is formed on the side surface by being lowered so as to be matched and the bottom surface side is a flat surface.

That is, since the conventional ski frame has a simple plate shape, when a large number of pallets in the folded state are moved in a stacked state, the ski frame has a simple plate shape. However, in the present invention, since the rectangular hollow tube material having the above-described structure is used as the ski frame in the present invention, remarkable toughness is exhibited. At the same time, the fork insertion portion is formed as a thin portion M portion as described below, so that the problem of thickening due to the use of the ski frame 7 as a thick saddle is avoided. It is.

  As described above, as shown in FIGS. 1 and 4, the ski frame 7 is configured to form the thin portion M portion in the upward state at two positions that match the fork insertion portion. It is comprised so that it may form with a brazing material.

  A fork insertion gap E is formed by interposing a spacer 9 between the pallet floor frame A and the ski frame 7.

  In the state shown in FIGS. 1 to 3, the forklift is moved by inserting the fork into the fork insertion gap E. When the pallet is not used or is returned after use, the side plate B is folded on the floor frame A, and a plurality of the pallets are stacked in the vertical direction in such a folded state. That is, such a folding method is performed in exactly the same manner as an existing folding pallet.

By the way, in this case, the smaller the thickness of each pallet is, the larger the number of stacks can be, and this is advantageous in transportation means where the height of containers and the like is limited. In the present invention, as described above, “the formation of the pallet floor frame in the pallet floor portion is combined with the same planar well beam by crossing each other with the thin portions M engaged with each other. Thinning is achieved by “comprising the horizontal beam 5 and the vertical beam 6”.

Furthermore, the fork insertion portion in the pallet floor portion is thinned by forming the thin portion M portion in the upward state at two intervals that coincide with the fork insertion portion. It has been.

  In the present invention, on the floor surface of the floor portion in the folding pallet and the fork insertion gap of the floor portion, the thinning is achieved based on the presence of the thin portion M provided on the brazing material constituting the floor. .
