Abstract

A pallet cover includes a deck. A plurality of flanges extend upwardly from the deck and a plurality of legs extend downwardly from the deck. The pallet cover includes a plurality of adjustable corner members that allow the pallet cover to fit pallets of varying sizes. The adjustable corner members operate in an “accordion-like” fashion so that they can be reused on multiple pallets and still retain their original size.

Description

BACKGROUND OF THE INVENTION

This invention relates to a pallet cover. Pallet covers are useful with wooden pallets. Pallet covers protect a load from splinters, nails, and other elements that can be on a pallet. Pallet covers also protect the pallet from the load. Plastic pallet covers are reusable and more durable than cardboard pallet covers.
Some pallet covers can be challenging to fit on wooden pallets. Wooden pallets have relatively large variations in dimension. The large variations in dimension can be due to manufacturing, moisture absorption, and damage by forklifts.
Other pallet covers protect a perimeter of the pallet and not a deck portion. However, this type of pallet cover can obstruct openings along the side of the wooden pallet which are used by a forklift or a pallet jack to engage and move the pallet.

SUMMARY OF THE INVENTION

A pallet cover according to the present invention includes a deck and a plurality of flanges extending upwardly from the deck. The flanges can prevent a load from shifting on a pallet. The flanges can also protect the load from equipment that may be used to move the pallet.
The pallet cover includes a plurality of protrusions that extend from a face on a leg. The plurality of protrusions allow stretch wrap, which is commonly used to cover a pallet during shipping, to be easily gripped.
The pallet cover includes a plurality of legs that extend downwardly from the deck to engage corners of the pallet. The pallet cover includes adjustable corner members that allow the pallet cover to fit pallets of varying sizes. The adjustable corner members function in an “accordion-like” manner. The adjustable corners allow the legs to extend outward to snugly fit a first pallet. When the pallet cover is removed from the first pallet, the adjustable corner members contract, and the legs return to their original positions. The pallet cover is then ready to use on a second pallet which could vary in size from the first pallet. This makes the pallet cover especially useful with wooden pallets, since they are known to have varying dimensions due to construction and environmental conditions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A pallet cover 10 according to the present invention is shown in FIG. 1. The pallet cover 10 includes a deck 12. A plurality of flanges 18 extend upwardly from the deck 12 at deck edges 14. The plurality of flanges 18 extend along the deck edge 14 between adjustable corner members 32 and deck corner portions 20.
The deck 12 includes a textured top surface 26. The textured top surface 26 includes a plurality of small vertical protrusions, such as bosses 28 shown. The bosses 28 extend from the deck 12. The textured top surface can also be produced by applying an adhesive spray 52, a textured strip 50, or by including additives into the plastic material to increase its coefficient of friction. A plurality of drain holes 30 are located on the deck 12 and drain the pallet cover.
FIG. 2 is a bottom perspective view of the pallet cover 10. A plurality of legs 22 extend downwardly from the deck 12. Each leg 22 forms a pocket to receive a pallet corner.
FIG. 3 is a side view of the pallet cover 10. FIG. 4 is a front view of the pallet cover 10. The plurality of flanges 18 help in preventing a load from shifting on the deck 12. The plurality of flanges 18 protect the load from a fork lift or a pallet jack.
FIG. 5 is an enlarged perspective view of the pallet cover 10 showing a plurality of protrusions 24. The plurality of protrusions 24 extend from a face of the leg 22. The plurality of protrusions 24 engage a pallet wrapping material 48, such as plastic stretch wrap used to secure and cover the goods on the pallet. The plurality of protrusions 24 also prevent the pallet wrapping material 48 from separating from the pallet cover 10 and surrounding only the product.
FIG. 6 is an enlarged perspective view of the pallet cover 10 showing an adjustable corner member 32. The adjustable corner member 32 functions in an “accordion-like” manner to fit pallets 34 with varying dimensions. When a force is applied to the legs 22, the adjustable corner members 32 allow the legs 22 to extend. The legs 22 extend to mate with a corresponding pallet corner on a first pallet. The pallet cover can be removed from the first pallet and the legs 22 will return to their original positions. A force can then be reapplied to the legs 22 to extend them by means of the adjustable corner members 32 to fit a second pallet that varies in size from the first pallet. When the legs 22 are in an extended position, the adjustable corner members 32 exert a force on the legs 22 to return them toward their original position.
FIG. 7 is a perspective view of the pallet cover 10 on a pallet 34. The lower portion of the deck 12 engages the top of the pallet deck 16. The pallet cover 10 allows for easy access to openings 38 and 40 on the front and side of the pallet 34. Openings 38 and 40 provide a way for a fork lift or pallet jack to engage the pallet 34.
The pallet cover 10 on the pallet 34 can be nested with a similar pallet cover 10′ and similar pallet 34′. A base portion of the similar pallet 34′ is received by the upper portion of the deck 12 of the pallet cover 10. The flanges 18 guide the base portion of the similar pallet 34′ onto the deck 12.
The pallet cover 10 can also be nested with the similar pallet cover 10′. The lower portion of the deck 12′ is received by the upper portion of the deck 12. The flanges 18 guide the similar pallet cover 10′ onto upper portion of the deck 12. The flanges 18 and 18′ and the legs 22 and 22′ engage each other to maintain the pallet covers in a nested position.
