CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. patent application Ser. No. 60/449,382, filed Feb. 24, 2003, which is hereby incorporated by reference in its entirety.[0001]

TECHNICAL FIELD

The present invention relates generally to pallet members, and more particularly to a pallet member that is constructed of individual interlocking members that can be easily stored.

BACKGROUND

There are a number of different pallet constructions that are commercially available for purchase. A pallet is basically designed as a load support member that is constructed to make it easier for transporting and/or storing bulk matter that is placed on a load bearing surface thereof. For example, industrial type pallets have features formed therein that permit a fork lift truck to carry a pallet that may contain a number of boxes or other types of containers (e.g., sacks) that are arranged in a predetermined pattern on the load bearing surface.

Pallets are often made of wood. The weight and bulk of wooden pallets results in high costs for transporting, storing and disposal of the pallets. Another problem is handling and storing pallets after use. Often they must be transported for reuse or refurbishment, further adding to their cost. Often, they are destroyed after use, further adding to already overloaded landfill facilities.

It is also known to construct a pallet of corrugated paperboard. Although use of corrugated paperboard is advantageous with respect to weight, bulk and recycling issues, new complications are introduced. The added complexity of corrugated pallets required to provide adequate stiffness and load support strength complicates use with lift apparatus such as fork lift trucks. Also, a large number of different pieces are often required to assemble the pallets, especially if used with different sized containers. Large numbers of parts adds to the cost of inventory and assembly costs of the pallets.

In addition to industrial type pallets, pallets can be designed for applicability more in a residence or small office. More specifically, many people store items in boxes that are placed in a cellar or garage. While, the consumer can simply box such items and place them on the ground surface, this may lead to damage or destruction of the boxes themselves since paperboard boxes attract moisture and as the reader will appreciate, basement floors and garage floors tend to be damp. In addition, in areas that are prone to flooding and/or rodent infestation, it is advantageous to elevate the boxes off of the ground surface. By placing the boxes or containers on the pallet, the items are elevated from the ground surface.

It is therefore desirable to provide a pallet that its formed of smaller individual parts that can easily be interlocked to form the pallet and disassembled for storage thereof.

SUMMARY

The present invention pertains to a pallet that its formed of smaller individual parts (pallet support members) that can easily be interlocked to form the pallet and disassembled for storage thereof.

According to one embodiment, a pallet kit formed of a number of individual support members that are engageable with one another to form a support pallet is provided. The kit includes a plurality of individual pallet support members that are arranged in an interlocking manner to form the support pallet, wherein each pallet support member has one or more interlocking features that permit each pallet support member to mate with one or more other pallet support member in an interlocking manner. The pallet support members are mated together by orientating the pallet support members in a grid-like pattern with the features aligned and then two pallet support members are interlocked with respect to one another by inserting one pallet support member into features of another pallet support member such that the two pallet support members are effectively interlocked with respect to one another.

In another embodiment, a pallet kit formed of a number of individual support members that are engageable with one another to form a support pallet is provided. The kit includes a plurality of individual pallet support members that are arranged in an interlocking manner to form the support pallet, wherein each pallet support member has one or more interlocking notches that permit each pallet support member to mate with one or more other pallet support members. Each notch is defined by a pair of vertical walls and a horizontal wall extending therebetween. The pallet support members are mated together by aligning the interlocking notches and then two pallet support members are interlocked with respect to one another by inserting one pallet support member into notches of another pallet support member such that the pallet support members are effectively interlocked with respect to one another. Each vertical wall is formed of first and second beveled surfaces that converge to a point that is spaced apart from the point defined by the beveled surfaces of the opposing vertical wall to permit the pallet support members to be angled with respect to one another at 90 degrees or at an angle other than 90 degrees.

Further aspects and features of the exemplary apparatus disclosed herein can be appreciated from the appended Figures and accompanying written description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring first to FIGS. 1-6, a [0036] pallet 10 according to one exemplary embodiment is illustrated. The pallet 10 has a support body 12 that includes an upper support surface 14 which acts as a load support surface and an opposing lower surface 16. In accordance with this embodiment, the pallet 10 is formed of a number of smaller, individual pallet support members 20 that are arranged in an interlocking manner to form the pallet 10. More specifically, each pallet support member 20 has one or more interlocking features that permit each pallet support member 20 to mate with one or more other pallet support member 20 in an interlocking manner. For example, each pallet support member 20 has one or more and preferably a plurality of notches 30 (e.g., a rectangular or square shaped notch). The notches 30 are placed at predetermined locations along the length of the pallet support member 20. In FIG. 1, each pallet support member 20 has three notches 30 formed therein. Each notch 30 is defined by two opposing vertical walls 32 and a horizontal wall 34 that extends therebetween.
The [0037] pallet support members 20 are mated together by orientating the pallet support members 20 in a grid like pattern with the notches 30 aligned and then two pallet support members 20 are interlocked with respect to one another by inserting one pallet support member 20 into another pallet support member 20 such that the two horizontal walls 34 seat against one another. In this position, the two pallet support members 20 are effectively interlocked with respect to one another. The pallet 10 itself is constructed by interlocking the various pallet support members 20 in the aforementioned manner. This size of the pallet 10 is variable as shown in the figures. It will be appreciated that this type of interlocking pallet 10 can easily and quickly be constructed and then taken apart by disengaging the pallet support members 20 from one another. FIG. 4 shows the pallet 10 in use and FIG. 5 shows the pallet 10 in a packaged state where the pallet support members 20 are stacked on top of another in several columns and a band 40 fits around the stacked members 20 to securely hold them in place. The band 40 can be formed of a paper product, such as cardboard, or it can be a plastic piece with such elasticity to accommodate insertion of the stacked members 20.
FIGS. 7-11 illustrate a second embodiment in which a [0038] pallet 100 is illustrated. The pallet 100 is formed of one or more flexible pallet support members 110 that are each extendable between a closed position and an open position. Each pallet support member 110 is an elongated structure, when completely opened, that is formed of a series of support base units 112 that are connected to one another by a flexible support hinge 114 that permits easy bending between the support base units 112 so that one unit 112 can be placed in one orientation compared to another base unit 112. The support hinge 114 has a thickness less then the units 112 to readily permit bending between the units 112. FIG. 9 shows two units 112 adjacent one another as a result of bending of the hinge 114 and FIG. 10 illustrates a support member 110 formed of three base units 112 in an open position, although not a linear orientation. FIGS. 8 and 11 show the support member 110 in a stored position. As illustrated, the pallet support member 110 can be arranged in a number of different orientations (e.g., zig-zag of varying degrees of openness between the units 112). Furthermore, more than one support member 110 can be used to construct the pallet 100. For example, two or more support members 110 can be arranged in spaced relation to form the pallet 100 and because the support members 110 are readily adjustable, the precise pattern of the pallet 100 and the support surface defined thereby is easily reconfigurable. In one embodiment, the base units 112 are formed as extruded urethane members and the hinge 114 is a hot pressed flat spot in the extruded urethane foam.
FIGS. 12-16 illustrate yet another embodiment of the present invention in which a [0039] pallet 200 is illustrated. In this embodiment, the pallet 200 is formed of a plurality of support members 210. Each of the support members 210 is in the form of an elongated support beam that includes interlocking features formed therein that permit each pallet support member 210 to mate with one or more other pallet support member 210 in an interlocking manner. For example, each pallet support member 210 has one or more and preferably a plurality of notches 220. The notches 220 are placed at predetermined locations along the length of the pallet support member 210. In FIG. 14, each pallet support member 210 has three notches 220 formed therein. Each notch 220 is defined by two opposing vertical walls 222 and a horizontal wall 224 that extends therebetween. Each vertical wall 222 is not a smooth surface but rather is formed of a pair of beveled surfaces 223, 225 that converge to a point 227 that is spaced apart from the point 227 of the opposing vertical wall 222. The distance between one point 227 to the opposing point 227 is about equal to or slightly less than a width of the pallet support member 210. The distance between one beveled surface 223 on one vertical wall 222 and the beveled surface 225 of the other vertical wall 222 is about equal to or slightly less than a width of the pallet support member 210. Similarly, the distance between one beveled surface 225 on one vertical wall 222 and the beveled surface 223 of the other vertical wall 222 is about equal to or slightly less than a width of the pallet support member 210. These dimensions permit one support member 210 to be interlocked with another support member 210 such that the two are not necessarily perpendicular to one another but rather they are angled with respect to one another by mating the two support members 210 such that one support member 210 is disposed between one beveled surface 225 and one beveled surface 223 or between one beveled surface 223 and one beveled surface 225.
The [0040] pallet support members 210 are mated together by orientating the pallet support members 210 with the notches 220 aligned and then two pallet support members 210 are interlocked with respect to one another by inserting one pallet support member 210 into another pallet support member 210 such that the two horizontal walls 224 seat against one another and the beveled surfaces 223, 225 engage one another. In this position, the two pallet support members 210 are effectively interlocked with respect to one another. The pallet 200 itself is constructed by interlocking the various pallet support members 210 in the aforementioned manner. This size of the pallet 10 is variable as shown in the figures. It will be appreciated that this type of interlocking pallet 200 can easily and quickly be constructed and then taken apart by disengaging the pallet support members 210 from one another.
FIGS. 17-19 illustrate individual pallet support members according to various other embodiments. FIG. 17 shows an individual [0041] pallet support member 300 that has a pair of side walls 302 with an inner reinforcing feature 304 which in the present embodiment assumes a wave like pattern. The member 300 includes a notch 306 formed in one face thereof to permit mating with another member 300 to form the pallet. FIG. 18 illustrates an individual pallet support member 310 where the reinforcing feature 304 is in the form of a series of X-shaped support beams extending between and being integral to the side walls 302. FIG. 19 illustrates another pallet support member 320 that is formed of a pair of side walls 322 that come together and are joined at select locations 324. In other words, each of the side walls 322 has a wave-like pattern that and at points where the side walls 322 converge and contact one another, a strengthened location 324 is formed. Preferably, a predetermined number of notches 326 are formed at select number of locations 324. Thus, the notches 326 should be formed at the locations 324 as opposed to where the side walls 322 are apart from one another. Each of the pallet support members of FIGS. 17-19 can be manufactured using an injection molding process or any other type of conventional manufacturing process.
FIG. 20 illustrates an individual [0042] pallet support member 330 according to another embodiment and is in the form of a corrugated plastic member. The member 330 is an elongated beam-like structure that has a plurality of notches 332 formed along one edge thereof that runs the length of the member 330 (e.g., an upper or lower edge of the member 330). In addition, one or more ends 334 of the member 330 include a notch 332 for facilitating mating between one pallet and another pallet. As shown in FIG. 21, when one pallet is assembled, each corner of the pallet is defined by distal end sections that protrude beyond an intersection of the two mated members 330. In other words, an end section of each pallet member 330 is free for mating and therefore, the notch 332 formed at the end of the member 330 is free to receive a connector 340 that serves to couple one pallet to another pallet. The connector 340 is in the form of a rectangular or square shaped member that has a pair of notches 342 formed at ends 344 thereof. The notch 344 is sized to mate with the notch 332 to permit the connector 340 to be received within the notch 332. A plane containing the connector 340 is preferably perpendicular to a plane containing and extending from one end to the other end of the member 330. While the connector 340 is removable, the coupling between the connector 340 is preferably of a snug or frictional fit so that the individual components remain in place. One notch 344 at one end receives one support member 330, while the other notch 344 at the other end receives another support member 330. Use of the connectors 340 also help keep the pallet units square with respect to one another. The individual members 330 can be packaged so that multiple colors are provided for in one package to permit the consumer to make a vibrant colorful pallet. The lengths of the members 330 can also be customized by the consumer since the members 330 can be tailored to a specific length by simply cutting the member 330 to this length. The use of corrugated fluted plastic to form the members 330 and the connector 340 is also very cost effective.
FIGS. 22[0043] a-h illustrate various shapes and constructions of pallet support members according to various embodiments. Each of these constructions can be made using an injection molding process. A number of the pallet support members include a reinforcing structure that is formed between and are integrally joined in select regions to the side walls of the members 330. In FIG. 22(h), the reinforcing structure can be made so that it represents a trade name of the product or the company that makes and/or sells the product or a logo or some other type of indicia. FIG. 22(a) shows a honeycomb structure.
FIG. 23 illustrates yet another feature of the present pallet assemblies. More specifically, a [0044] pallet locking member 400 is provided for mating with an assembled pallet which is generally indicated at 410. As with the other embodiments, the pallet 410 is formed of a plurality of individual pallet support members that have contoured ends 412 that are constructed to mate with complementary features of the pallet locking member 400. In the illustrated embodiment, each end 412 is constructed so that it contains a locking tab 413. There are a series of spaced, parallel tabs 413 that are formed along each side of the pallet 400.
The locking [0045] member 400 is a flexible locking member that assumes a square or rectangular shape when it is assumes a locked position. The locking member 400 is formed of a number of wall segments 415 that are arranged to that they pivot or flex about a hinge section 417 formed between and connecting adjacent wall segments 415. In other words, the locking member 400 can be opened into a long, elongated member that can be folded about hinge sections 417 to form the closed locking member 400. One end of the member 400 includes a locking feature 420, such as a tab, that is constructed to mate with a complementary receiving feature 422 formed at the other end of the member 400. When the locking feature 420 mates with the receiving feature 422 and the member 400 is folded about the hinge sections 417 and the locking member 400 mates with the pallet 410, the locking member 400 serves and provides a border that extends around the outer walls of the pallet 410. In the illustrated embodiment, the receiving feature 422 is merely a slot and the locking feature 420 is in the form of a protruding locking tab that is received within the slot 422 so as to maintain the form and shape of the locking member 400.
In order to mate the locking [0046] member 400 with the pallet 410, a number of slots or slits 423 are formed between the two ends of the member 400. The slits 423 are complementary to the locking tabs 413 formed at the ends 412 such that the locking tabs 413 can be received therethrough so as to couple each side of the pallet 410 to a respective side of the locking member 400 as is shown in FIG. 24. By frictionally fitting the locking tabs 413 into the slits 423, the two facing sides are mated together such that at least one side of the locking member 400 is coupled to the adjacent, parallel side of the pallet 410. The slits 423 are carefully formed at spaced locations that align with the locations of the locking tabs 413 so as to permit reception of the tabs 413 into respective slits 423 as shown in FIG. 24. However, it will be understood that there can be additional unused slits 423 so long as there is a corresponding slit 423 for each tab 413. The tabs 413/slits 423 thus serve also to locate the two members with respect to one another. To complete the coupling between the members 400 and the pallet 410, the locking tab 420 mates with the receiving feature 422.
The locking [0047] member 400 thus serves to lock the pallet 410 in place to produce a very strong and durable pallet or riser which can easily be assembled and disassembled by the consumer by merely unlocking and decoupling the individual components.
While this invention has been particularly shown and described with references to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims.
