Description

Assembled pallet with expandable loading area {ASSEMBLED PALLET WITH CAPABLE OF INCREASING LOAD AREA}

The present invention relates to an assembled pallet, and in detail, four rectangular expansion members on the outside of a square main body are rotated 90° and fastened to each other in a male-female fastening method, and slits are formed on the upper and lower surfaces of the main body and the expansion member, respectively. By fastening the slit channel to the slit in a sliding manner in a "#" shape, the fastening force is increased, thereby expanding the loading area to provide a high-strength structure that can minimize compressive load and breakage that is not affected by the loading load. This is about a possible assembled pallet.

A pallet is a stand on which loads are loaded and moved using equipment such as a forklift, and is generally manufactured as an integrated piece using wood, plastic, metal, etc.

Wooden pallets have high price competitiveness, but are vulnerable to the environment, so they are used one-time and cause quarantine problems.

Plastic pallets, the most widely used, can be used more frequently than wood, but they are vulnerable to breakage and cannot be repaired when damaged, so the burden of waste disposal is high.

Metal pallets, developed as a replacement for wood and plastic pallets, have a high price per weight and depend on exports for raw materials, so they are subject to price fluctuations and require an excessive number of processing and assembly workers, which reduces price competitiveness.

In addition, existing integrated pallets require multiple molds to produce pallets of various sizes, so an increase in mold production costs is essential. Partial repair or replacement is not possible, and there is no specific plan on how to recover and dispose of damaged pallets. It is not provided.

Therefore, it is necessary to develop a pallet that can be expanded and assembled without using multiple molds, can be partially repaired and replaced, and can recycle damaged pallets, so the loading area can be expanded, which is Domestic Patent Publication No. 10-2192166. Variable Pallet, No. 10-0656290, a variable loading area pallet, is posted.

As shown in FIGS. 1 and 2, the variable pallet with an expanded loading area includes a main body 10 on which cargo is loaded on the upper surface 101, and a first stopper seating portion ( 130), a first stopper 110, which is formed by recessing the first guide groove 113 on the side and is provided on the first stopper seating portion 130 to be raised to the upper surface 101 of the main body 10. A protrusion 135 is formed to protrude on the inside of the seating portion 130 and is inserted into the first guide groove 113, and is provided on the first stopper seating portion 130, so that the first stopper 110 is connected to the main body 10. When raised to the upper surface 101, the first support member 140, which supports one end 117 of the first stopper 110, is coupled to the first stopper 110 to support the upper surface 101 of the main body 10. It consists of an expanding expansion panel 20 and a first long bolt 70 connecting the first stopper 110 and the expansion panel 20, and the expansion panel 20 is coupled to the first stopper seating portion 130. The expansion panel connecting portion 210 is formed, and the expansion panel connecting portion 270 is formed.

In addition, as shown in FIGS. 3 and 4, the variable loading area pallet has separation legs ( 12) is installed, a square lower plate 13 is installed on the lower part of each separation leg 12, and coupling grooves 14 are formed on all sides to allow the auxiliary supports 20 and 30 to be coupled. Main stand (10); Separation legs 22 are installed at the front, rear, and center of the lower part of the upper plate 21, and at the same time, a lower plate 23 is installed below each separation leg 22, and has a vertical length V1 of the main support 10. It has a vertical length (V2) and a horizontal length (H2) that is smaller than the vertical length (V2), and a coupling protrusion (25) for coupling to the main support (10) is formed on the left or right side, and the front and rear sides. A pair of both side auxiliary supports (20) in which a coupling groove (24) is formed to allow the front and rear auxiliary supports (30) to be coupled to each other; Separation legs 32 are installed on both sides and in the center of the upper plate 31, and at the same time, a lower plate 33 is installed on the lower part of each separation leg 32, and the horizontal length H1 of the main support 10 is It has a horizontal length (H3) that is the sum of the horizontal lengths (H2) of each auxiliary support (20) on both sides coupled to both sides of the main support (10) and a vertical length (V3) that is smaller than the horizontal length (H3), at the rear or front. It is provided with a pair of front and rear auxiliary supports (30) on which coupling protrusions (35) are protruding so as to be coupled to the main support (10) and the auxiliary supports (20) on both sides.

However, since this type of conventional pallet is a type in which the expanded portion is joined by protrusions and grooves, there is a problem in that when a load is applied to the connecting portion, the corresponding portion spreads and is damaged.
