Definitions
- the present invention relates to a pallet made of synthetic resin and, more particularly, to a three piece welded plastic pallet for supporting loads that is adapted for use with a lifting device.
- Plastic pallets are becoming more commonly used in today's industries. Plastic pallets have many advantages over those made of wood or even metal. Plastic pallets are stronger and more durable than wooden pallets and are impervious to most chemicals, do not rot and do not absorb moisture. Plastic pallets are also lighter than wood or metal pallets. Moreover, plastic pallets are not subject to corrosion or rusting.
- plastic pallets in use today are constructed of top and bottom horizontal decks connected together by a series of columns or posts and have entryways for the forks of a lifting device such as a fork lift.
- a lifting device such as a fork lift.
- many of the present plastic pallets have a large package height in order to be sufficiently strong.
- Such pallets are heavier and use relatively large amounts of plastic material.
- Other plastic pallets with a lower package height may not provide sufficient strength for heavier loads.
- a need still exists for a plastic pallet which is reasonably inexpensive, sturdy, lightweight and still possesses sufficient strength for heavier loads.
- the pallet also should have sufficient stiffness to receive the fork of a lifting device without reducing the strength of the pallet.
- a further object of the invention is to provide plastic pallet which possesses sufficient strength to support heavy loads but which is still relatively lightweight and durable.
- a still further object of the invention is to provide a plastic pallet made from a synthetic resin such as polyethylene or polypropylene which is impervious to most chemicals, does not rot, does not absorb moisture, does not rust and maintains a constant tare weight.
- the present invention achieves the above and other objects by providing a three piece plastic pallet constructed of a synthetic resin material and having a top deck with an upper surface and a lower surface.
- a middle deck is provided having an upper plate portion and lower portion spaced from each other and connected by plurality of columns extending between a lower surface of the upper plate portion and a top surface of the lower plate portion, with the upper plate portion having a top surface attached by welding to the lower surface of the top deck.
- a bottom deck is provided having an upper surface and a lower surface with the upper surface of the bottom deck being attached by welding to a bottom surface of the lower plate portion of the middle deck.
- Reinforcement members may be provided between the top deck and the middle deck and/or between the middle deck and the bottom deck to provide further strength to the pallet. Entryways for prongs of a lifting device such as a forklift may be formed on all four sides of the pallet.
- the lower surface of the top deck has a plurality of first rib members thereon which mate with and are attached to a plurality of second rib members on the top surface of the upper plate portion of the middle deck and the bottom surface of the lower plate portion of the middle deck has a plurality of third rib members thereon which mate with and are attached to a plurality of fourth rib members on the upper surface of the bottom deck.
- FIG. 1 is an isometric view of a three piece plastic pallet according to the present invention
- FIG. 2 is an exploded, right side, perspective view from the top of the plastic pallet illustrating the three separate pieces;
- FIG. 3 is an exploded, left side perspective view from the top showing the three pieces of the plastic pallet
- FIG. 4 is an exploded perspective view from the bottom of the pallet.
- FIG. 5 is an exploded top perspective view of another embodiment of the present invention showing reinforcement bars between the top and middle decks and between the middle and bottom decks.
- FIGS. 1-4 of the drawings Illustrated in FIGS. 1-4 of the drawings is a pallet 10 according to the present invention which includes a top deck 12 , a middle deck 14 and a bottom deck 16 .
- a plurality of entryways 18 are provided on the sides of the pallet with each side being constructed with two entryways to receive the prongs of a lifting device such as a forklift.
- the top, middle and bottom decks are all made of a synthetic resin or plastic material such as polypropylene or polyethylene.
- the three decks preferably are molded using an injection molding process.
- the top deck 12 has a smooth upper surface 22 as shown in FIGS. 1-3 and a lower surface 24 having a plurality of ribs 26 which cross each other to form a plurality of diamond shaped boxes as shown in FIG. 4 .
- the top deck also is provided with a plurality of holes constituting hand holds 28 adjacent the sides thereof.
- middle deck 14 is constructed having an upper plate portion 30 and a lower plate portion 32 connected by a plurality of columns or posts 34 .
- the columns 34 extend between the upper plate portion 30 and the lower plate portion 32 whereby the two plate portions are spaced from each other a sufficient amount to permit the entryways 18 to be constructed along each side of the middle deck.
- the columns 34 are aligned in rows of three both lengthwise and widthwise of the middle deck.
- Each of the columns has a hollow interior 35 provided with reinforcing dividers 37 .
- the upper plate portion 30 of the middle deck has a top surface 36 and a lower surface 38 .
- the top surface 36 of the upper plate portion is provided with a plurality of ribs 40 which cross each other to form diamond shaped boxes of the same configuration as the ribs 26 on the lower surface 24 of the top deck whereby the ribs 40 and 26 mate when the top deck is welded to the upper plate portion of the middle deck.
- the lower plate portion 32 of the middle deck has a top surface 42 and a bottom surface 44 having a plurality of ribs 46 thereon which cross each other to form rectangular boxes.
- the lower plate portion 32 is provided with a plurality of rectangular cutout portions 48 , which reduce the amount of material required and also reduce the weight of the pallet.
- the bottom deck 16 has an upper surface 50 and a smooth lower surface 52 .
- the upper surface 50 of the bottom deck is provided with a plurality of ribs 54 which cross each other to form a plurality of rectangular boxes having the same configuration and which mate with the ribs 46 on the bottom surface of the lower plate portion of the middle deck when the bottom deck is attached by welding to the middle deck.
- the bottom deck 16 is provided with a plurality of rectangular holes 56 which match with the rectangular holes 48 of the middle deck.
- the holes 56 in the bottom deck reduce the amount of material required to form the deck and also lessen the overall weight of the pallet.
- the top deck 22 is formed by injection molding as one integral piece
- the middle deck 14 is formed by injection molding as a second single integral piece
- the bottom deck 16 is formed by injection molding as a third integral piece.
- the top deck is attached by a suitable welding process such as flat plate welding to the upper plate portion of the middle deck and the bottom deck is attached by a suitable welding process such as flat plate welding to the lower plate portion of the middle deck.
- Other suitable forms of plastic welding may be used such as sonic welding or infrared radiation welding.
- This construction results in a pallet of superior strength.
- the entire middle deck is formed as an integral piece and then the top and bottom decks are welded to the middle deck to form a solid structure. This construction results in an I-beam type effect since the columns extend between the top deck and the bottom deck.
- the I-beam type construction results in a pallet with superior strength.
- the pallet maintains a deck thickness close of that of wood while still providing superior strength.
- the upper surface of the top deck and the lower surface of the bottom deck are smooth which makes them easy to clean. This feature is especially important in connection with food and beverage products.
- the entire pallet is made from a synthetic resin such as polyethylene or polypropylene, it is impervious to most chemicals, does not rot, does not absorb moisture, has a constant tare weight and does not rust or otherwise deteriorate.
- reinforcement bars 60 may be added between the top deck and the upper plate portion of the middle deck and additional reinforcement bars 62 may be added between the lower deck and lower surface of the bottom deck.
- Channels 64 may be formed in one or both of the lower surface of the top deck and the top surface of the upper plate portion of the middle deck and in one or both of the bottom surface of the lower plate portion of the middle deck and the upper surface of the bottom deck.
- the reinforcement bars may be pultruded bars constructed of steel or fiberglass.

Description
- 1. Field of the Invention
- The present invention relates to a pallet made of synthetic resin and, more particularly, to a three piece welded plastic pallet for supporting loads that is adapted for use with a lifting device.
- 2. Description of the Related Art
- Plastic pallets are becoming more commonly used in today's industries. Plastic pallets have many advantages over those made of wood or even metal. Plastic pallets are stronger and more durable than wooden pallets and are impervious to most chemicals, do not rot and do not absorb moisture. Plastic pallets are also lighter than wood or metal pallets. Moreover, plastic pallets are not subject to corrosion or rusting.
- Many of the plastic pallets in use today are constructed of top and bottom horizontal decks connected together by a series of columns or posts and have entryways for the forks of a lifting device such as a fork lift. In order to be strong enough to support heavier loads, however, many of the present plastic pallets have a large package height in order to be sufficiently strong. Such pallets are heavier and use relatively large amounts of plastic material. Other plastic pallets with a lower package height may not provide sufficient strength for heavier loads.
- Accordingly, a need still exists for a plastic pallet which is reasonably inexpensive, sturdy, lightweight and still possesses sufficient strength for heavier loads. The pallet also should have sufficient stiffness to receive the fork of a lifting device without reducing the strength of the pallet.
- It is an object of the present invention to provide a plastic pallet made of a synthetic resin which is formed from three separate pieces which are welded together.
- A further object of the invention is to provide plastic pallet which possesses sufficient strength to support heavy loads but which is still relatively lightweight and durable.
- It is another object of the invention to provide a plastic pallet which has a smooth outside surface which is easy to clean and is particularly useful in connection with handling foods and beverages.
- A still further object of the invention is to provide a plastic pallet made from a synthetic resin such as polyethylene or polypropylene which is impervious to most chemicals, does not rot, does not absorb moisture, does not rust and maintains a constant tare weight.
- The present invention achieves the above and other objects by providing a three piece plastic pallet constructed of a synthetic resin material and having a top deck with an upper surface and a lower surface. A middle deck is provided having an upper plate portion and lower portion spaced from each other and connected by plurality of columns extending between a lower surface of the upper plate portion and a top surface of the lower plate portion, with the upper plate portion having a top surface attached by welding to the lower surface of the top deck. A bottom deck is provided having an upper surface and a lower surface with the upper surface of the bottom deck being attached by welding to a bottom surface of the lower plate portion of the middle deck. Reinforcement members may be provided between the top deck and the middle deck and/or between the middle deck and the bottom deck to provide further strength to the pallet. Entryways for prongs of a lifting device such as a forklift may be formed on all four sides of the pallet.
- The lower surface of the top deck has a plurality of first rib members thereon which mate with and are attached to a plurality of second rib members on the top surface of the upper plate portion of the middle deck and the bottom surface of the lower plate portion of the middle deck has a plurality of third rib members thereon which mate with and are attached to a plurality of fourth rib members on the upper surface of the bottom deck.
- These and other features and advantages of the present invention will become more apparent with reference to the following detailed description and drawings.
-
FIG. 1 is an isometric view of a three piece plastic pallet according to the present invention; -
FIG. 2 is an exploded, right side, perspective view from the top of the plastic pallet illustrating the three separate pieces; -
FIG. 3 is an exploded, left side perspective view from the top showing the three pieces of the plastic pallet; -
FIG. 4 is an exploded perspective view from the bottom of the pallet; and -
FIG. 5 is an exploded top perspective view of another embodiment of the present invention showing reinforcement bars between the top and middle decks and between the middle and bottom decks. - Illustrated in
FIGS. 1-4 of the drawings is apallet 10 according to the present invention which includes atop deck 12, amiddle deck 14 and abottom deck 16. A plurality ofentryways 18 are provided on the sides of the pallet with each side being constructed with two entryways to receive the prongs of a lifting device such as a forklift. The top, middle and bottom decks are all made of a synthetic resin or plastic material such as polypropylene or polyethylene. The three decks preferably are molded using an injection molding process. - The
top deck 12 has a smoothupper surface 22 as shown inFIGS. 1-3 and alower surface 24 having a plurality ofribs 26 which cross each other to form a plurality of diamond shaped boxes as shown inFIG. 4 . The top deck also is provided with a plurality of holes constituting hand holds 28 adjacent the sides thereof. - As shown in
FIGS. 2 , 3 and 4,middle deck 14 is constructed having anupper plate portion 30 and alower plate portion 32 connected by a plurality of columns orposts 34. As best shown inFIG. 4 , thecolumns 34 extend between theupper plate portion 30 and thelower plate portion 32 whereby the two plate portions are spaced from each other a sufficient amount to permit theentryways 18 to be constructed along each side of the middle deck. Preferably, thecolumns 34 are aligned in rows of three both lengthwise and widthwise of the middle deck. Each of the columns has ahollow interior 35 provided with reinforcingdividers 37. - The
upper plate portion 30 of the middle deck has atop surface 36 and alower surface 38. Thetop surface 36 of the upper plate portion is provided with a plurality ofribs 40 which cross each other to form diamond shaped boxes of the same configuration as theribs 26 on thelower surface 24 of the top deck whereby theribs - The
lower plate portion 32 of the middle deck has atop surface 42 and abottom surface 44 having a plurality ofribs 46 thereon which cross each other to form rectangular boxes. Thelower plate portion 32 is provided with a plurality ofrectangular cutout portions 48, which reduce the amount of material required and also reduce the weight of the pallet. - The
bottom deck 16 has anupper surface 50 and a smoothlower surface 52. Theupper surface 50 of the bottom deck is provided with a plurality ofribs 54 which cross each other to form a plurality of rectangular boxes having the same configuration and which mate with theribs 46 on the bottom surface of the lower plate portion of the middle deck when the bottom deck is attached by welding to the middle deck. - The
bottom deck 16 is provided with a plurality ofrectangular holes 56 which match with therectangular holes 48 of the middle deck. Theholes 56 in the bottom deck reduce the amount of material required to form the deck and also lessen the overall weight of the pallet. - In manufacturing the
pallet 10, thetop deck 22 is formed by injection molding as one integral piece, themiddle deck 14 is formed by injection molding as a second single integral piece and thebottom deck 16 is formed by injection molding as a third integral piece. To assemble the three pieces into the pallet of the present invention, the top deck is attached by a suitable welding process such as flat plate welding to the upper plate portion of the middle deck and the bottom deck is attached by a suitable welding process such as flat plate welding to the lower plate portion of the middle deck. Other suitable forms of plastic welding may be used such as sonic welding or infrared radiation welding. This construction results in a pallet of superior strength. The entire middle deck is formed as an integral piece and then the top and bottom decks are welded to the middle deck to form a solid structure. This construction results in an I-beam type effect since the columns extend between the top deck and the bottom deck. The I-beam type construction results in a pallet with superior strength. - Moreover, the pallet maintains a deck thickness close of that of wood while still providing superior strength. In addition, the upper surface of the top deck and the lower surface of the bottom deck are smooth which makes them easy to clean. This feature is especially important in connection with food and beverage products.
- Since the entire pallet is made from a synthetic resin such as polyethylene or polypropylene, it is impervious to most chemicals, does not rot, does not absorb moisture, has a constant tare weight and does not rust or otherwise deteriorate.
- In a second embodiment of the invention shown in
FIG. 5 , additional strength may be added to the pallet by the use of reinforcement bars. As shown inFIG. 5 , reinforcement bars 60 may be added between the top deck and the upper plate portion of the middle deck and additional reinforcement bars 62 may be added between the lower deck and lower surface of the bottom deck. Channels 64 may be formed in one or both of the lower surface of the top deck and the top surface of the upper plate portion of the middle deck and in one or both of the bottom surface of the lower plate portion of the middle deck and the upper surface of the bottom deck. The reinforcement bars may be pultruded bars constructed of steel or fiberglass. - Numerous other modifications and adaptations of the present invention will be apparent to those skilled in the art and thus, it is intended by the following claims to cover all such modifications and adaptations which fall within the true spirit and scope of the invention.
