Description

palette

  The present invention relates to a pallet, and more particularly to a multi-purpose pallet made of a disassembled member.

  Wooden pallets are generally used for easy storage and transportation. These pallets are generally square and include a top and bottom deck made of a series of long wooden planks and at least two sturdy wooden beams provided between them.

A pallet 1 is disclosed, typically made of sheet metal of galvanized steel or aluminum. The pallet 1 includes an upper deck 5, a lower deck 10, and at least two elongated supports 15 that fix the upper deck 5 and the lower deck 10. As shown in FIGS. 1, 5 a to 5 d and 8, each support 15 extends separately between the upper deck 5 and the lower deck 10, and is connected to the central web plate 30 by an inclined portion 35. A first portion 16 and a second portion 17 having an upper web plate 20 and a lower web plate 25 are provided. The web plates 20, 25, and 30 of the first portion 16 and the second portion 17 are typically detachably fixed by fixing means 4 such as screw type fasteners inserted into the holes 45, respectively. The lower web plate 25 is detachably fixed to the upper deck 5 and the lower deck 10, respectively. In a preferred form, the central web plate 30 is provided perpendicular to the upper deck 5 and the lower deck 10. The fixing means 40 can be welded or riveted. The pallet 1 can be easily repaired by processing a welded part or rivet with a drill and performing re-welding or re-riveting.

Typically, the parts 16 and 17 of the support 15 are placed adjacent to each other in line symmetry, and the parts of the two central web plates 30 are fixed to each other by fixing means 40 such as screw-type fasteners, spot welds, blind rivets or the like. The The pallet 1 can include a countersink hole or opening in the hole 45 to shield the securing means 40 below the adjacent surface. This prevents sharp portions such as bolt ends from protruding from the upper deck 5 and the lower deck 10. As clearly shown in FIG. 3, the elongated support 15 may also include a reinforcing strip 50 to provide additional support to the support 15 when the pallet 1 is used for heavy objects. it can. The reinforcing band 50 is attached along the central web plate 30 in the hole 45 for the fixing means 40. The pallet 1 can also include additional attachments to further include features. For example, the upper deck 5 and the lower deck 10 can be provided with corrugations as clearly shown in FIGS. 2, 7a and 7b. Cover plates, end caps 55, 65, etc. as shown in FIGS. 3 and 4 can be advantageously used.

The upper web plate 20 and the lower web plate 25 shown in FIG. 1, FIG. 5a and FIG. 8 are load supporting flanges, and an opening 47 is provided between the upper and lower web plates. I will provide a. Separation of portions 16 and 17 allows only one side edge of support 15 to be replaced as needed. In the preferred form, web plates 20 and 25 are utilized in an adjacent state. A round, non-sharp edge 39 is preferably provided between the web plates 20 and 25 and the ramp 35. The overall dimensions of all members can be varied depending on the pallet 1 of the required size.

  FIG. 2 shows a standard 1000 cm × 1200 cm pallet. The size of the pallet 1 can be changed according to demand, for example, 1165 cm × 1165 cm. The upper deck 5 and the lower deck 10 can be variously changed, such as a wave shape, a flat shape, and a curved surface. For example, in the case of a corrugated shape, the directionality, shape, and uniformity can be appropriately changed according to the type and weight of the load to be handled. In this embodiment, a rugged galvanized steel corrugated deck is shown. The corrugated surface provides maximum surface contact area while maintaining structural suitability. However, a 100% flat surface 79 can be used instead of the corrugation, or provided on the corrugation (see FIG. 4), or combined as appropriate.

The advantage of this pallet 1 is that all members can be easily disassembled and reconstructed, and damaged members can be easily replaced. A processing sleeve 60 (see FIG. 4), which can be provided with any material, can be added to cover the edges and increase strength. An end cap 55 can be added to improve the aesthetics of the pallet, increase the impact resistance, and cover the opening and edge at the end of the support 15. If a corrugated deck is used, an edge band 65 (see FIG. 3) can be provided to seal the corrugated openings from a hygienic point of view. 2 and 6a
6c, 7a and 7b show an opening 75 for a fork lift truck or a pallet truck wheel. The pallet 1 can have beam bodies (not shown) between the supports 15 or in the corrugations to provide additional support for very heavy loads.

FIG. 4 shows an additional member that includes a lip 77 formed on the corrugations to eliminate sharp edges and increase resistance to impact from a forklift. A separate sleeve 60 can also be used as described above. The lip body 77 is also useful for increasing the horizontal strength of the pallet 1. This embodiment has a further sheet material 79 on the upper surface of the corrugated deck, and further has a reinforcing band 50. The sheet material 79 may be galvanized steel, wood, plastic or other material.

  FIGS. 5 a to 5 d and 8 show different embodiments of the support 15. These embodiments are used for different fixture combinations and provide easy access to the support 15. Additional members 80 can be added to receive the upper deck 5 and the lower deck 100 as shown in FIGS. 5a and 5b.

  FIGS. 6a to 6c and FIGS. 7a and 7c are further embodiments of the present invention and show details of the opening 75 of the pallet 1 that provides four-way insertion for the lifting device.

  FIG. 8 shows another embodiment of the present invention having fixing means 40 in the form of screws and rivets. Web plates 20 and 25 are folded inward to eliminate sharp edges.

  The pallet 1 can be completely disassembled, and all members can be replaced quickly and quickly at low cost. The pallet 1 is very sturdy depending on the angle of the members constituting the parts 16 and 17 and has structural stability and load distribution against rotational movement. The size and angle of the pallet member can be changed according to various uses. Dangerous edges on the horizontal side edges of each support 15 are eliminated. A small cross section at the end is provided for the fork portion of the forklift in a form that maximizes the width of the opening 75, and is connected to the support 15 and bolted, screwed or welded to the upper and lower decks 5 and 10. Making it easy. The hole and the opening 45 are provided in a concave shape, and the protrusion is excluded. There are no joints on the outer surface, which provides resistance to dirt buildup. The interior space is designed to a minimum and the dirt area is minimized. The internal space is minimized to maximize the effectiveness of the cleaning pressure hose. The support 15 can be made of galvanized steel or aluminum.

The additional sheet material layer 79 can be provided by steel, wood, plastic, paper board, composite or fiber material. For example, the steel support 15 supports a wood deck and can be fixed with a screw-type nail tool, a bolt or the like. The shape of the support 15 makes it possible to use a medium-high horizontal reinforcement 50 for particularly heavy loads. The shape of the support can be designed to provide 4-way pallet availability. The upper deck 5 and the lower deck 10 can be covered so that they can be used 100% if necessary for the purpose of using the pallet 1, and decks can be added. Hygiene for the food industry can also be considered. The deck board can be a winding part 77 so as not to form a sharp part. The sleeve 60 adds rigidity to the forklift and pallet truck. The shape of the support 15 makes it possible to use a wooden deck if necessary. The shape of the support allows the steel strip to be attached to the cover recess. The top surface shape of the deck plate can have a rolled-up end of 45 ° to 60 °, eliminating sharp edges. The separate deck plate can have a horizontal angle cover attachment.
