Description

4-Way Pallet < RTI ID = 0.0 >

The present invention relates to a four-way pallet, and more particularly to a four-way pallet in which the top plate and the support of the pallet are reinforced by the reinforcing member made of corrugated cardboard and the support by the wooden.

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.

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 composed of a plurality of vertical supports 210 and a plurality of horizontal supports 240, which intersect with each other and are fitted 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 vertical support body 210 is composed of one or two central vertical supports 220 and two or four outer vertical supports 230. The outer vertical supporting bodies 230 are disposed on the left and right sides of the central vertical supporting body 220, respectively, and have the same shape. 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. This definition applies not only to the vertical support but also to the horizontal support.

As shown in FIG. 4, the central longitudinal support body 220 has a plurality of two-stage coupling grooves 222 and two fork-lift fork-through grooves 227 formed by removing a part of the frame 221.

It is preferable that the plurality of two-stage coupling grooves 222 are as many as the number of the horizontal supports at the central portion and the outer portion of the central vertical support body 220, but some of them may be formed as a single coupling groove. The two-stage coupling groove 222 is opened toward the upper surface 228 of the pallet 10 which engages with the upper plate 100. The two-stage coupling groove 222 has a stepped groove 223 formed by dipping deeper into the lower surface from the upper surface 228 and a stepped groove 224 formed by dipping shallower than the slotted portion 223. Therefore, the end of the short groove portion 224 is formed higher than the end of the long groove portion 223, and a step 225 is formed between them. The two-stage coupling groove 222 may be formed in a shape in which two short groove portions 224 are formed on both sides of the long groove portion 223 and a single short groove portion 224 is formed only on one side of the long groove portion 223 Or the like.

The two fork-lift fork-through grooves 227 are formed to be opened to the lower side between the two-stage coupling grooves in the center portion and the two-stage coupling grooves in the outer frame portion. It is preferable that the depth of the forklift fork penetrating groove 227 is equal to the depth of the long groove portion 223 of the two-

As shown in FIG. 4, the outer vertical support 230 has a plurality of single coupling grooves 236 formed by removing a part of the frame 231 from the central portion and the outer peripheral portion, and two fork- And has a groove 237. The single coupling grooves 236 are formed by the number of the transverse supports and open to the lower side. The depth of the single engaging groove 236 is greater than the depth of the elongated groove portion 223 of the two-stage engaging groove 222 same. The two fork-lift fork-through grooves 237 are formed to be opened to the lower side between the single engaging groove of the central portion and the single engaging groove of the outer frame portion. The depth of the forklift fork penetrating groove 237 is preferably equal to the depth of the engaging groove 236.

As shown in FIG. 4, the lateral support 240 is formed by removing one part of the frame 241 and one or two central horizontal supports and two or four outer lateral supports having the same shape. Or four outer two-stage coupling grooves 242 and one or two central single coupling grooves 246 and two fork-lift fork-through grooves 247. The outer two-stage coupling groove 242 is located at the outer frame portion and is opened toward the upper surface 248. [ The outer two-stage coupling groove 242 is formed by stepwise forming a long groove portion 243 formed by dipping deeply in the lower surface direction from the upper surface 248 and a stepped groove portion 244 formed by being shallower than the long groove portion 243. Therefore, the end of the short groove portion 244 is formed higher than the end of the long groove portion 243, and a step 245 is formed between them. And the central single engagement groove 246 is opened to the lower side. The center single coupling groove 246 is formed with only a single groove unlike the outer two coupling groove 242 and the depth of the central single coupling groove 236 is smaller than the depth of the long groove portion 243 ). ≪ / RTI > The two fork-lift fork grooves 247 are open to the lower side between the outer two-stage coupling groove 242 and the central single coupling groove 246 and between the outer two-stage coupling groove 242 and the central single coupling groove 246 . The depth of the forklift fork passage groove 247 is preferably equal to the depth of the central single engagement groove 246.

In the support 200, the long groove portion 223 of the two-stage coupling groove 222 of the central vertical support body 220, the single coupling groove 236 of the outer vertical support body 230, The depth of the long groove portion 243 of the engaging groove 242 and the depth of the central single engaging groove 246 are equal to each other and it is also preferable that the depth is the same as the depth of the forklift fork through grooves 227, 237 and 247. The depths of the short groove portions 224 and 244 are smaller than the depths of the long groove portions 223 and 243. It is also preferred that the widths and lengths of the top surfaces 228, 238 and 248 of the respective supports 220, 230 and 240 and the heights of the supports 220, 230 and 240 coincide with each other.

The arrangement positions of the long groove portion 223 and the short groove portion 224 in the two-stage coupling groove 222 of the central longitudinal support body 220 are irrelevant if they are formed adjacent to each other stepwise. That is, the arrangements in which the long groove portion 223 is formed on the right side and the short groove portion 224 is formed on the left side and the arrangement in which the long groove portion 223 is formed on the left side and the short groove portion 224 is formed on the right side can be used equally. This arrangement can be applied to the arrangements of the long groove portion 243 and the short groove portion 244 in the outer two-stage coupling groove 242 of the horizontal support body 240 as it is. 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.

The plurality of vertical supports 210 and the plurality of horizontal supports 240 are fitted to each other by fitting the central vertical support 220 to the center of the plurality of horizontal supports 240, And engaging the engaging grooves 246 with the elongated grooves 223 of the two-stage engaging grooves 222 of the central longitudinal support body 220. [ Since the depth of the long-hinged portion 223 of the two-stage coupling groove of the central vertical supporting body 220 coincides with the depth of the central coupling recess 246 of the horizontal supporting body 240 and the height of the central vertical supporting body 220 The height of the horizontal support body 240 is equal to each other so that the upper surface 228 of the central vertical support body 220 and the upper surface 248 of the horizontal support body 240 are located at the same height after they are combined.

Next, the plurality of outer vertical supporting bodies 230 are combined with the plurality of horizontal supporting bodies 240, respectively. Concretely, the single engagement groove 236 of the outer vertical support body 230 is engaged with the long groove portion 243 of the outer two-step engagement groove 242 of the horizontal support body 240, respectively. At this time, the depth of the coupling groove 236 of the outer vertical support body 230 coincides with the depth of the long groove portion 243 of the outer two-stage coupling groove 242 of the horizontal support body 240, The upper surface 238 of the outer vertical support 230 and the upper surface 248 of the horizontal support 240 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 reinforcing member 300 is fitted into the short groove portion 244 of the outer two-stage coupling groove 242 of the horizontal support body 240 and the short groove portion 224 of the two-stage coupling groove 222 of the central vertical support body 220 And the width and height thereof are equal to the width and depth of the short groove portions 224 and 244. [ 4, the reinforcing member 300 includes a relatively long reinforcing member 310 passing through the short groove portion 244 of the outer two-stage coupling groove 242 of the plurality of lateral supports 240, Groove 224 of the two-stage coupling groove 222 of the support body 220, that is, a relatively short reinforcement member 320 passing through one short-groove portion 224. It is preferable that the length of the long reinforcing member 310 coincides with the length of the vertical support member 210. The length of the short reinforcing member 320 is equal to the distance from the inner side of one outer vertical supporting member 230 to the inner side of the other outer vertical supporting member 230 so that one end of the reinforcing member is connected to one outer vertical supporting member 230 It is preferable that the other end of the reinforcing member comes in contact with the inner side of the other outer vertical support body 230. 4, when the long reinforcing member 310 is disposed in contact with the inner side surface of the outer vertical supporting member 230, one end of the short reinforcing member 320 is long reinforced in contact with the outer vertical supporting member 230 And the other end of the short reinforcing member comes in contact with another long reinforcing member 310 which is in contact with the inner side surface of the other outer vertical supporting member 230. [

In addition, a slice reinforcing member 330 may be provided on the side of the central transverse support body 240. The intergranular reinforcements 330 engage one side of the central longitudinal support 220. And their distal ends engage the side of the transverse support 220 or the short reinforcement 320 abutting the transverse support 220, respectively.

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 laminating direction of the corrugated cardboard constituting the supports 200 is a direction perpendicular to the upper surfaces 228, 238 and 248 of the supports 200 coupled to the upper plate 100, Direction. 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.
