Nestable pallet with runners

Abstract

A nestable pallet having three rows of feet extending downward from a support surface is provided. In one aspect, the outer rows of feet are attached by runners at a bottom portion of each foot and the middle row of feet does not include runners. The support surface includes openings to accommodate the outer rows of feet with runners, and the middle row of feet of a like pallet. The absence of runners in the middle row and a corresponding larger opening, allows for greater support area in that portion of the pallet. The pallet can also include reinforcements extending perpendicular to the runners.

FIELD OF THE INVENTION

The present invention is generally related to nestable pallets having runners connecting the feet of the pallet.

DESCRIPTION OF THE PRIOR ART

Typically pallets fall into two categories—nestable (which are usually plastic) and stackable. One benefit of nestable pallets is that—when nested—they efficiently condense to a small space. This ability to nest facilitates return shipping of empty pallets. The tradeoff for this is less strength and conveyability of the pallet. In contrast to nestable pallets, stringers incorporated into most stackable designs give the pallet significantly improved rigidity, particularly when supported by the tines of a forklift, and improved conveyability. Nestable pallets, however, must rely solely on the deck to hold shape, and support boards to allow for use on conveyors.

One solution to increase strength (at least in one direction) and conveyability of the nestable pallet is to provide runners connecting feet of the pallet (such as that shown in EP 2067708A1). However, such nestable pallets included at least three rows of feet and three corresponding runners connecting the feet in each respective row. To properly nest with other like pallets, each pallet required openings in the upper support surface to accommodate all the rows of runners. The large openings needed to accommodate the runners reduced the usable space on the upper support surface. They also compromised strength across the width of the pallet.

The present invention provides nestable pallets with improved strength and nestable pallets with more support surface area in the central portion of the support surface or deck.

SUMMARY OF THE INVENTION

The present invention provides nestable pallets with improved strength and deflection properties, and nestable pallets with increased surface area on the upper support surface and strength through the center of the pallet.

The pallets with increased surface area include three or more rows of feet extending downward from the support surface. Unlike prior nestable pallets, the nestable pallets having increased surface area only have runners connecting the outer rows of feet, and do not include runners connecting the inner or middle row (or rows) of feet. Accordingly, openings in the upper support surface to accommodate the runners of a like pallet are not required for the inner row (or rows), allowing that area to be used for supporting goods or other items on the nestable pallet.

In accordance with one aspect of the invention, a nestable pallet with increased support surface space is provided. The nestable pallet comprises a generally rectangular support surface having a first row of feet extending downward from proximate a first side of the support surface. The feet in the first row of feet are connected by runners at a lower portion of each of the first row of feet. An opening is provided proximate the first side of the support surface for allowing nesting of the first row of feet and runners of a like pallet. The pallet includes a second row of feet extending downward from proximate a second side of the support surface. Similar to the first row of feet, the feet in the second row of feet are connected by runners at a lower portion of each of the second row of feet. An opening proximate the second side of the support surface is provided for allowing nesting of the second row of feet and runners of the like pallet. The pallet further includes a third row of feet extending downward from proximate a middle portion of the support surface and a plurality of openings proximate the middle portion of the support surface corresponding with each of the feet in the third row of feet. The feet in the third row of feet are not connected to each other by runners. Accordingly, the support surface includes a first support area directly between a first foot of the third row of feet and a second foot of the third row of feet. This effectively prevents the pallet from nesting with a pallet having three runners (i.e., a runner connecting the middle feet in addition to the feet proximate the sides of the pallet). That is, this support area (between the openings) would have to be open if runners were connecting all of the rows of feet.

The pallet can further include a second support area directly between the second foot of the third row of feet and a third foot of the third row of feet. Similar areas can be provided if the pallet includes more than three feet in the middle row.

Additionally, each of the openings in the middle portion of the support surface can include internal support structure.

In accordance with an aspect of the invention, a pallet having additional support surface is provided. The pallet includes a generally rectangular support surface and a first row of feet extending downward from proximate a first side of the support surface. Each of the feet in the first row of feet are connected by a first set of runners at a lower portion of each of the feet. An opening is formed proximate the first side of the support surface. The opening is configured for allowing nesting of a first row of feet and runners of a like pallet. The pallet includes a second row of feet extending downward from proximate a second side of the support surface. Similar to the first row of feet, each of the feet in the second row of feet are connected by a second set of runners at a lower portion of each of the feet. An opening proximate the second side of the support surface is provided for allowing nesting of a second row of feet and runners of the like pallet. The pallet also includes a third row of feet extending downward from proximate a middle portion of the support surface and a plurality of openings proximate the middle portion of the support surface, each of the plurality of openings corresponding with one of the feet in the third row of feet. The support surface includes a first support area directly between a first opening of the plurality of openings for a first foot of the third row of feet and a second opening of the plurality of openings for a second foot of the third row of feet. In view of the support area between the first two openings in the third row, the pallet cannot be configured to stack with any pallets having runners in the middle row. However, it has this additional area for use in supporting goods or other items placed on the pallet.

Additionally, the pallet includes a second support area directly between the second opening of the plurality of openings for the second foot of the third row of feet and a third opening of the plurality of openings for a third foot of the third row of feet. Again, this prohibits stacking with a pallet having runners connecting feet in the middle row.

Each foot in the pallet can include an internal support structure extending upward in the interior of the respective opening. The internal support structure of the first foot can include a first rib extending from a central portion of the support structure to a periphery of the first opening. Similarly, the internal support structure of the first foot can include a second rib extending from the central portion of the support structure to the periphery of the first opening.

The nestable pallet can further include a plurality of reinforcements. The reinforcements can extend perpendicular to the first and second sets of runners. Alternatively, reinforcements can run parallel to the runners. The reinforcements can be steel tubes or bars. The steel tubes can have a square cross-sectional shape, or other suitable shape.

In accordance with an aspect of the invention, another nestable pallet is provided. The pallet includes a rectangular support surface, a first foot and a second foot extending downward from the support surface in a first row and a first runner connecting a bottom portion of each of the foot and the second foot. A first opening is provided in the support surface over the first foot, second foot and first runner. The pallet also includes a third foot and a fourth foot extending downward from the support surface in a second row and a second runner connecting a bottom portion of each of the third foot and the fourth foot. A second opening is provided over the third foot, fourth foot and second runner. The pallet further includes a fifth foot and a sixth foot extending downward from the support surface in a third row, a third opening over the fifth foot and a fourth opening over the sixth foot. The support surface includes a portion directly between the fifth foot and the sixth foot.

The pallet can also include internal supports, ribs or reinforcements as described herein.

In accordance with another aspect of the invention, a pallet with three rows of feet connected by runners is provided. The pallet includes a generally rectangular support surface and a first row of feet extending downward from proximate a first side of the support surface. The feet in the first row of feet are connected by a first set of runners at a lower portion of each of the first row of feet. The pallet also includes an opening proximate the first side of the support surface for allowing nesting of a first row of feet and runners of a like pallet. The pallet further includes a second row of feet extending downward from proximate a middle portion of the support surface. The feet of the second row of feet are also connected by a second set of runners at a lower portion of each of the second row of feet. The pallet also includes an opening proximate the middle portion of the support surface for allowing nesting of a second row of feet and runners of the like pallet. The pallet further includes a third row of feet extending downward from proximate a second side of the support surface. The feet of the third row of feet are also connected by a third set of runners at a lower portion of each of the third row of feet. The pallet also includes an opening proximate the second side of the support surface for allowing nesting of a third row of feet and runners of the like pallet. The pallet further includes a reinforcement extending from the first side to the second side. The reinforcement is perpendicular to the first, second and third sets of runners.

Preferably, any of the pallets described are formed from plastic or other suitable material.

Further aspects of the invention are shown in the Figures and described herein.

DETAILED DESCRIPTION

While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

Referring to FIGS. 1-8, a nestable pallet 10 in accord with one aspect of the present invention is shown. The nestable pallet 10 includes a generally rectangular support surface 12 having a first side, a second side, a first end and a second end. A plurality of feet 14 extend downward from the support surface 12. In this embodiment, the feet 14 are positioned in three rows, a first outer row 16, a middle row 18 and a second outer row 20. Each row 16, 18 and 20 includes three feet 14. The feet 14 in the outer two rows 16 and 20 of the pallet 10 are shown connected by runners 22. As shown in FIGS. 5 and 6, the runners 22, feet 14 and support surface 12 collectively define openings 23 in the side of the pallet 10.

As shown in FIG. 1, each of the outer rows 16, 20 of feet 14 that are connected by runners 22, have corresponding openings 24, 26 on the upper support surface 12. As is evident in the Figures, the openings 24, 26 for these outer rows 16, 20 extend almost the entire length of the pallet 10 to accommodate the runners 22. The openings are used to accommodate feet/runners from a like nestable pallet that is placed on the pallet 10 (i.e., to nest with and reduce the volume of such pallets when shipped empty).

In contrast to the outer rows 16, 20, the feet in the middle row are not connected by runners. Accordingly, the support surface 12 in the middle portion of the pallet 10 only requires openings 28 sufficiently sized to accommodate the feet 14. This allows for the support surface 12 to include areas 30 directly between the feet 14 openings 28 in the middle row 18 for supporting goods or other items placed on the pallet 10. This effectively increases the support surface area over similar dimensioned pallets having three rows of feet all of which are connected by runners. The area directly between the feet 14 openings 28 in the middle row 18 does not have to be completely solid. That is, the area can be or include a lattice like structure, or other similar structure having other openings, so long as some portion of the area is generally level with the remaining support surface of the pallet and useable as a support surface. Having a support surface between the openings would not allow such a pallet to nest with a pallet having three rows of feet where each row is connected by runners.

The openings 24, 26 and 28 allow for the pallet 10 to nest with a like pallet. The “like” pallet can be identical to the instant pallet 10, or one that is sufficiently similar so that it fits in the openings of the pallet 10 in a nesting relationship.

The openings 28 (or parts of outer row 16, 20 openings 24, 26) for the feet 14, can be completely hollow, or the feet 14 can include internal support structure 32 for providing additional strength extending upward in the opening. In this latter instance (as shown in the Figures), the openings can be formed to include multiple sections.

Unlike prior nestable pallets having runners 22, the pallet 10 shown in FIGS. 1-8 does not include runners connecting the middle row 18 of feet 14. Because the pallets are designed to nest with similar like pallets, the pallets must have openings in the support surface to accommodate the runners. Removing runners from the middle row 18 allows the pallet 10 to have more surface area on the support surface 12.

As shown in FIG. 7, the bottom 34 of the support surface 12 can include a plurality of downwardly extending ribs 36 for increased strength of the pallet 10.

In the pallet of FIGS. 1-9, the internal support structure 32 includes ribs 35 that extend side-to-side (of the opening) in a width direction (i.e., perpendicular to the runners 22). That is, the ribs 35 extend from a portion of the internal support structure located in a central portion of the opening to a periphery of the opening. These ribs 35 provide additional strength to inhibit or stop deck deflection of the pallet 10.

FIGS. 10 and 11 provide a pallet 40 where the internal structure 32 does not include ribs 35. Rather, the pallet 40 includes reinforcements 38 inserted into the pallet to provide strength against deck deflections.

FIG. 10 shows the reinforcements 38 being inserted into openings on a side of a pallet 40. FIG. 11 shows the pallet 10 with the reinforcements 38 fully in place. The reinforcements 38 shown are steel tubes (or possibly solid bars) having a square cross-sectional shape. However, other shapes and materials can be used. The reinforcements 38 are shown going across the width of the pallet 40 (i.e., perpendicular to the runners 22). The pallet can be configured to also receive reinforcements across the length of the pallet (i.e., parallel to the runners 22).

FIGS. 12-15 show another aspect of the present invention. A pallet 42 is shown having three rows of feet 44 where each row includes runners 46 connecting the feet 44 in the row. Similar to the pallet 10 of FIGS. 1-9, the pallet 42 of FIGS. 12-15 includes feet 44 having internal structures 48 with side-to-side extending ribs 50. As discussed, the ribs 50 provide additional strength in this direction to inhibit deck deflection. Alternatively, the pallet can be configured to receive reinforcements 38 perpendicular to the runners as described with respect to FIGS. 10 and 11.

The pallets shown are preferably formed from a molded plastic, or other similar material.

Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
