Description

2-Way Pallet < RTI ID = 0.0 >

The present invention relates to a two-way pallet, and more particularly to a two-way pallet in which the top plate and the support of the pallet are made of cardboard and the strength of the support is reinforced by wooden reinforcement.

The pallet is a pedestal for loading various cargoes and is widely used when transporting freight using forklifts and the like. In general, the pallet is formed into a rectangular plate shape. The pallet is conventionally made mainly of wood. The wooden pallet is vulnerable to impacts, the parts bonded by the nails are structurally fragile, various pests and germs can multiply easily, and must be thoroughly sterilized and disinfected during the import and export process. Plastic pallets molded from synthetic resin have the advantage of being able to mass-produce because they are excellent in formability and can not grow microorganisms, but they are heavier than wooden pallets, the cost of raw material synthetic resin is high, .

In this situation, paper pallets made of paper such as corrugated cardboard have gradually become widely used. The paper pallet is manufactured by attaching a paper tube made of paper or corrugated paper to a pallet top plate made of corrugated paper. Pallet legs are also made of pulp.

Korean Patent Laid-Open Publication No. 2009-0091563 (published on Aug. 28, 2009) discloses a pallet and a pallet leg made of a pulp molding. In this patent application, a pallet is composed of a pallet top plate and a plurality of pallet legs attached and fixed to the bottom of the top plate by an adhesive. The pallet leg is made of a pulp molding, and the upper leg plate and the lower leg plate having a plurality of quadrangular prism pillars are adhered to each other so that their quadrangular prisms are zigzagged to each other. However, when the pallet leg having such a structure is easy to manufacture, it is difficult to withstand a large load, and when an external impact from the side of the leg, for example, the pallet leg is touched due to insufficient driving operation of the forklift, It is liable to be damaged by the cracks.

Korean Patent Laid-Open Publication No. 2009-0112365 (published on October 28, 2009) discloses a pallet leg having a dual structure and being formed into pulp and a pallet including the same. In this patent application, the pallet consists of a pallet top plate and a plurality of pallet legs attached thereto by an adhesive. Although this pallet leg has the advantage of being able to withstand large loads, the weakness of the external impact from the side of the leg is still not improved.

Korean Utility Model Laid Open Publication No. 2012-0001143 (published Feb. 20, 2012) discloses a pallet leg capable of withstanding a large load as well as an external impact from the side of a leg and a pallet including the same. This utility model registration application was devised by the present inventor in order to overcome the disadvantages of the prior art described above.

The inventor of the present invention came to the present invention as a result of further efforts to devise a more robust and easy to manufacture pallet, especially a paper pallet.

Accordingly, the object of the present invention is to provide a more robust and easy to manufacture pallet, especially a two-way paper pallet. More particularly, the object of the present invention is to provide a two-way paper pallet in which the pallet top and support are made of corrugated cardboard and the strength of the support is reinforced by wooden reinforcements, thereby making it more robust and easy to manufacture.

In order to accomplish the above object, a two-directional pallet according to the present invention includes an upper plate on which a cargo is loaded, a support for supporting the upper plate, and a reinforcement body for reinforcing the strength of the support in combination with the support. The support is comprised of three to six transverse supports and three to six transverse supports crossing each other and joined together by grooves formed in them. The vertical support body has a two-step engagement groove, the number of which is equal to the number of the horizontal supports, opened to the upper surface of the upper support. The transverse support body has two or four outer single engagement grooves which are opened to the lower side and are formed on the outer peripheral portion and one or two central single engagement grooves formed on the central portion and are provided on the lower side between the outer single engagement groove and the central single engagement groove And has two open forklift fork through grooves. The two-stage coupling groove of the vertical support body is formed by stepwise forming a groove groove portion formed by being deeply punched in the lower surface direction from the upper surface and a groove groove formed by being shallower than the groove groove portion. The longitudinal support body and the lateral support body are engaged with each other by the fitting method so that the longitudinal support body is vertically spaced apart and then the engagement grooves of the transverse support body are fitted to the longitudinal groove portions of the two- And is formed by fitting. And the reinforcing member is fitted in each of the recesses of the two-stage coupling grooves of the vertical supports.

The upper plate and the support are preferably formed of corrugated cardboard.

The reinforcing member is preferably made of wood.

Between the upper plate and the support, between the upper plate and the reinforcement member, between the support members in the engagement grooves, and between the support and the reinforcement member, an adhesive is preferably formed.

Preferably, the lamination direction of the corrugated cardboards constituting the supports is a direction toward one of the opposite side surfaces which is formed perpendicular to the upper surface of the support bodies coupled to the upper plate.

The two-step coupling groove may have a shape in which the two short groove portions are formed on both sides of the long groove portion, or a shape in which the short groove portion is formed only on one side of the long groove portion.

Since the two-way pallet according to the present invention is manufactured by combining corrugated supports and reinforcing members in a fitting manner and then assembled with the upper plate, it is easy to manufacture, and a support for supporting the pallet is provided on the reinforcement It is possible to exert a stronger supporting force even between the joining portions between the supports, which is more robust.

Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in the drawing, the pallet 10 according to the present invention includes a top plate 100 on which cargo is loaded, a supporting body 200 for supporting the top plate 100, and a supporting body 200, And a reinforcement body 300 for reinforcement. At this time, it is preferable that the upper plate 100 and the support 200 are formed of corrugated board, and the reinforcement 300 is formed of wood.

The support 200 is constituted by a plurality of vertical supports 210 and a plurality of horizontal supports 220, which are mutually intersected and joined in a fitting manner by grooves formed in them. Here, the horizontal and vertical directions are arbitrarily defined in order to distinguish the direction in which they are disposed, and are relatively. The number of the vertical supports 210 is three to six, and the number of the horizontal supports 220 is three to six.

As shown in FIG. 4, the vertical support 210 has a plurality of two-stage coupling grooves 212 formed by removing a part of the frame 211. Since the pallet according to the present invention is a two-directional pallet, the vertical support body 210 is not provided with a forklift fork penetration groove, and only the horizontal support body 220 is provided with a forklift fork penetration groove, as described below.

The number of the plurality of two-stage coupling grooves 212 is preferably the same as the number of the horizontal supports in the vertical support body 210, but a part thereof may be formed as a single coupling groove. The two-stage coupling groove 212 is opened toward the upper surface 218 which engages with the upper plate 100 of the pallet 10. The two-stage coupling groove 212 is formed by stepwise forming a long groove portion 213 formed by dipping deeply in the lower surface direction from the upper surface 218 and a short groove portion 214 formed by being shallower than the long groove portion 213. Therefore, the end of the short groove portion 214 is formed to be higher than the end of the long groove portion 213, and the step 215 is formed between them. The two-stage coupling grooves 212 may be formed in a shape in which two short grooves 214 are formed on both sides of the long groove portion 213 and only one short groove portion 214 is formed only on one side of the long groove portion 213 Or the like.

It is preferable that the plurality of two-stage coupling grooves 212 in the vertical support 210 are formed at uniform intervals, but they may be formed at irregular intervals depending on the case.

As shown in FIG. 4, the horizontal support 210 includes two or four outer single coupling grooves 222 and one or two central single coupling grooves 223 formed by removing a part of the frame 221, And two fork-lift fork-through grooves 224.

In this specification, the center or central portion refers to an area between two forklift fork through grooves as described below, and the outline or outline refers to a forklift fork through groove outer area.

The outer single engaging groove 222 and the central single engaging groove 223 are formed so as to be open to the bottom side with only a single groove and the depths thereof are set to be equal to each other in the longitudinal grooves 212 of the two- (213). The two fork-lift fork-through grooves 224 are formed to be open to the lower side between the outer single coupling groove 222 and the central single coupling groove 223. The depth of the forked fork penetrating groove 224 is preferably equal to the depth of the central single engaging groove 223, but may be deeper or shallower.

In the support 200, it is preferable that the widths and lengths of the upper surfaces 218 and 228 of the supports 210 and 220 and the heights of the supports 210 and 220 coincide with each other.

The arrangement positions of the long groove portion 213 and the short groove portion 214 in the two-stage coupling groove 212 of the vertical support body 210 are irrelevant if they are formed adjacent to each other stepwise. That is, the arrangement in which the long groove portion 213 is formed on the right side and the short groove portion 214 is formed on the left side and the arrangement in which the long groove portion 213 is formed on the left side and the short groove portion 214 is formed on the right side can be used equally. In addition, the two-stage coupling grooves may have a groove formed only on one side of the elongated groove, but may have two grooves formed on both sides of the elongated groove.

Now, with reference to FIG. 4, a description will be given of a fitting engagement between the supports 200 and a fitting engagement of the reinforcing member to the support thus combined.

First, the plurality of vertical support bodies 210 and the plurality of horizontal support bodies 220 are fitted to each other by fitting the vertical support bodies 210 in such a manner that the vertical support bodies 210 are vertically spaced apart at appropriate intervals, The engaging grooves 222 and 223 are fitted into the elongated groove 213 of the two-stage engaging groove 212 of the vertical support body 210, respectively. At this time, since the depth of the elongated groove 213 of the two-stage coupling groove of the vertical support body 210 coincides with the depth of the coupling grooves 222 and 223 of the horizontal support body 220, The upper surfaces 218 of the vertical support 210 and the upper surface 228 of the horizontal support 220 are positioned at the same height after they are coupled.

In this state, when the support members 200 are directly coupled with the upper plate 100, the supporting force to withstand the load of the object placed on the upper plate 100 is sufficient at the portion where the coupling grooves are fitted, May result in somewhat warped, which means that the bearing capacity in this area is somewhat lacking. The present invention combines a reinforcement to reinforce the support of the support in this area.

Thus, after the coupling of the supports is completed, the reinforcing body 300 is coupled to the support. The reinforcing member 300 is a rectangular plate member, particularly a plate member made of wood. The reinforcement member 300 is fitted and joined to the notches 214 of the two-step engagement grooves 212 of the vertical supports 210. The width of the reinforcement member 300 is the same as the width of the short- Is equal to the depth of the short groove portion 214. [

The support 200 and the reinforcing member 300 thus combined are engaged with the upper plate 100 on the upper surface thereof. It is simple in construction that the coupling between the upper plate 100 and the supporting body 200 and the coupling between the upper plate 100 and the reinforcing body 300 are made by bonding with an adhesive. It is also preferable that the support bodies 200 are joined by an adhesive agent at portions where the support bodies 200 are in contact with each other in addition to the fitting engagement. This is also the same between the supports 200 and the reinforcement bodies 300.

The direction of lamination of the corrugated cardboards constituting the supports 200 is a direction perpendicular to the upper surfaces 218 and 228 of the supports 200 coupled to the upper plate 100, . According to the laminating direction of the corrugated cardboard, since the support body can exert a high supporting force against the load pressing perpendicularly to the top plate 100, it provides an excellent supporting force to the corrugated paper pallet.

On the other hand, FIGS. 5 and 6 show a perspective view of a partially disassembled two-directional pallet according to another embodiment of the present invention. It is apparent that the present invention can include not only the embodiments illustrated in Figs. 5 and 6 but also many other embodiments belonging to the utility model registration claims set forth below.
