El BY Fi arb l r ssl'fk v ATTORNEYS MULTICIIANNELED MEMBER AND STRUCTURES FORMED THEREWITH The present invention relates to a multichanneled member and more particularly to a multichanneled member adapted to assemble with like multichanneled members to form structures, such as load bearing pallets.

Heretofore, pallets constructed of wood were nailed, or nailed and glued. Nails worked out and the nail holes enlarged during use and the exposed nail heads damaged merchandise stored thereon. Many pallets have runners which prevent entrance of tying material and truck forks from a pair of its sides thereby limiting the flexibility of stowage arrangements and restricting the aisle arrangements for manipulating the loads. Prior metal pallets were expensive and required a plurality of sections to form same and paper pallets are not durable and are not adapted to support heavy loads. Pallets combining wood decks and metal columns require expensive machinery to form the connection between the metal and wood.

The principal objects of the present invention are: to provide a multichanneled member adapted to assemble with like multichanneled members in normal relation and in longitudinal relation to form structures, such as load bearing pallets, containers, and the like; to provide such a multichanneled member wherein the channels therein are sized to receive an edge or an end of the like member; to provide a reuseable load bearing pallet formed of a plurality of the multichanneled members wherein the pallet is capable of supporting heavy loads during stowage and transportation thereof; to provide such a pallet adapted to be lifted using mechanical pallet handling equipment from any of its sides; to provide such a pallet adapted for easy passage of banding or other tying material through the pallet from any of its sides during securing the load to the pallet; to provide a strong, lightweight, inexpensive and durable pallet; to provide such a pallet having top and bottom decks spaced apart vertically by and interlocked with a plurality of like multichanneled members; to provide a pallet formed of a plurality of like multichanneled members which may be assembled economically, easily, simply, accurately and speedily; and to provide such a multichanneled member and pallet made therefrom which eliminates the aforementioned difficulties.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way of illustration and example certain embodiments of this invention.

Referring more in detail to the drawings:

The reference numeral 1 generally designates a multichanneled member adapted to assemble with like multichanneled members in normal relation and in longitudinal relation wherein channels therein are sized to receive an edge or an end of like multichanneled members to assemble together to form structures, such as load bearing pallets, containers, and the like. The like multichanneled members 1 each have wall portions arranged in laterally spaced rows 2 and 3 with the wall portions in one row being parallel with but longitudinally offset from the wall portions in the other row and with wall portions 4 extending laterally between the rows 2 and 3 and edge walls 5 and 6 extend laterally from ends of the wall portions in one of the rows, for example, row 2 to form a plurality of side-by-side channels opening in opposite directions including edge channels 7 and 8 respectively.

The multichanneled member 1 is illustrated as having intermediate channels 9 and 10 adjacent the edge channels 7 and 8 respectively and opening in an opposite direction thereto. Centered between the edge walls 5 and 6 is a double width channel 11 sized to receive a pair of the like multichanneled members therein with the free edges of the edge walls thereof in engagement or with the wall portions in row 2 in back-toback engagement.

Each of the edge channels 7 and 8 and the intermediate channels 9 and are sized to receive one of the edge walls 5 or 6 ofa like multichanneled member 1 therein whereby the multichanneled members are extending in the same longitudinal direction with the respective rows of wall portions 2 and 3 thereof in normal relation. Each of the edge channels 7 and 8 and the intermediate channels 9 and 10 are substantially identical in size and are sized to receive one end of a like multichanneled member 1 therein whereby the multichanneled members are in non-rial relation with the respective rows of wall portions 2 and 3 thereof also in normal relation.

In the illustrated multichanneled member l, the distance between the free edge of the edge walls 5 and 6 and the top side or surface of the row 2 of wall portions, as seen in FIG. 1, is substantially identical to the distance between facing surfaces of the edge channels 7 and 8 and the intermediate channels 9 and 10 and substantially identical to one-half the distance between facing surfaces of the double width channel 11.

It is desirable that the portions of the multichanneled member I be formed with precise dimensions particularly for thickness, width, spacing of the wall portions to permit assembly with like multichanneled members to form various structures, therefore, the multichanneled members are extruded sections, preferably aluminum for lightness in weight.

The multichanneled members 1 may be assembled together to form a plurality of different structures, such as a load bearing pallet 12, as shown in FIGS. 2 and 3, having a top deck 13 and a bottom deck or support means M and a plurality of support members 15 extending between the multichanneled members or slats in the top and bottom decks l3 and 14 wherein the support members 15 are positioned to interengage within selected channels within the multichanneled members or slats in the top and bottom decks l3 and 14.

In the illustrated load bearing pallet 12, the top and bottom decks l3 and 14 respectively are formed of a plurality of elongate laterally spaced slats in the form of the multichanneled members 1 having the free edges of the respective edge walls in facing relation wherein the respective top surface of the row 2 of wall portions, as seen in FIG. 1, forms the upper surface of the top deck 13 and the lower surface of the bottom deck or support means 114. Opposite ends of the slats or multichanneled members 1 in the top and

bottom decks

13 and 14 are received in the edge channels 7 and 8 respectively of

side members

16 and 17.

The support members 15 are vertically extending and longitudinally spaced along vertically aligned multichanneled members or slats in the top and bottom decks l3 and 14 to define openings or spaces to permit arms (not shown) of a lifting apparatus (now shown), such as a fork lift truck, to enter the pallet 12 between the support members 15 at either end thereof. Banding or other tying material may also be extended through the pallet between the spaced support members 15 to secure a load of merchandise thereon.

It is desirable to permit the arms of the lifting apparatus to enter the pallet 12 through the

side members

16 and 17 to thereby provide flexibility in positioning the pallets relative to an aisle in a storage area, therefore, the

side members

16 and 17 each have a plurality of apertures 18 therein, each sized to permit arms of the lifting apparatus to enter the pallet 12 through the

respective side member

16 or 17.

In the illustrated structure, the apertures 18 are formed by cutting out and removing a center portion of the multichanneled members forming the

side members

16 and 17. The removed portions include the wall portions 4 forming the intermediate channels 9 and 10 and double width channel 11 therebetween. It is preferable to provide a surface rather than an edge of the wall portions in the row 3 to be engaged by the arms of the lifting apparatus, therefore, suitable stiffening members 19 formed of structural shapes, such as channels, angles, and the like are positioned in the intermediate channel 9 adjacent the upper edge of the

side members

16 and 17 and are suitably secured therein, as by spot welding. The stiffening members 19 strengthen the

side members

16 and 17 at the apertures 18 therein and provide a surface to be engaged by the arms of the respective lifting apparatus.

It is desirable to guide the arms of the lifting apparatus into the spaces between the support members in the ends of the pallet 12, therefore, the exterior edge wall of the multichanneled member at each end of the pallet 12 is bent inwardly to form a ramp surface to guide the arms or prongs of the fork lift into the load bearing pallet 12.

After the various multichanneled members are assembled together to form the load bearing pallet 12, the members are suitably secured together, preferably by spot welding at the respective edge walls, channels, and ends thereof. It is noted that opposite ends of the

side members

16 and 17 are received in one of the edge channels of the support members 15 positioned at the corners of the pallet 12 whereby the load bearing pallet 12 thus formed is extremely strong when compared to conventional paper, wooden or metal pallets especially in resistance to lateral forces due to the interlocking action of the multichanneled members in the respective channels therein.

It should be noted that the arrangement of the multichanneled members or slats in the top deck includes a pair of the multichanneled members 1 in side-by-side engagement at the center thereof, however, the multichanneled members I may be arranged to provide support for any specific load. The upper surface of the top deck 13 may be covered with a suitable material, such as plywood, to provide a smooth surface for the top deck 13.

It is preferable that the top deck 13 of the load bearing pallet 12 be treated to increase the frictional resistance between the top deck 13 and merchandise placed thereon, therefore, the top deck 13 is sprayed with urethane to form a thin coating on the top deck 13.

FIGS. 4 to 7 inclusive, illustrate a modified load bearing pallet 20 having a top deck 21 formed of a plurality of laterally spaced multichanneled members 1 and a bottom deck or support means 22, also formed of a plurality of laterally spaced multichanneled members I with support members 23 extending therebetween and in the illustrated structure, the support members 23 are vertically directed and have opposite ends received in the edge channels 7 and 8 of the top and bottom slats.

It is preferable to have a greater number of the multichanneled members 1 in the top deck 21 than in the bottom deck 22 to provide greater surface area for supporting a load thereon. However, the portions of members in the top and bottom decks receiving opposite ends of the support members 23 must be vertically aligned. In the illustrated structure, there are five slats in the top deck and three slats in the bottom deck, however, any arrangement having every other top slat vertically aligned with a bottom slat with support members 23 extending therebetween may be assembled depending on the size of pallet desired and the load to be supported.

Opposite ends of the top and bottom slats are received in

side members

24 and 25 and in the illustrated structure, the ends of the top and bottom slats are received in the edge channels 7 and 8 respectively of the

side members

24 and 25. Opposite ends of the

side members

24 and 25 are received in one of the edge channels of the support members 23 positioned at the corners of the pallet 20 whereby each of the multichanneled members in the modified pallet 20 are assembled with a like multichanneled member for interlocking engagement therewith and when the multichanneled members are suitably secured together, preferably by spot welding at the respective edge walls, a pallet is provided which is extremely strong in resistance to lateral forces.

FIGS. 8 to II inclusive, illustrate a further modified pallet 30 having a plurality of laterally spaced top slats 31 to form a top deck and a bottom deck or support means 32 vertically spaced therefrom by a plurality of vertically directed support members 33. The support members 33 are vertically extending and longitudinally spaced along the top slats 31 to permit arms of the lifting apparatus to pass therebetween whereby the pallet may be lifted.

Horizontally extending

side members

34 and 35 receive opposite ends of the top slats 31 in the edge channel adjacent the upper edge thereof. Portions of the

side members

34 and 35 are removed, as indicated at 36, to provide access for the arms of the lifting apparatus to pass through the

side members

34 and 35 and between the support members 33 whereby the pallet may be lifted from any side thereof. In the illustrated structure, the portion removed is a lower edge portion and leaves the double width channel 11 intact and extends from a lower edge of the

side members

34 and 35 to the wall portion 4 forming a lower edge surface of the double width channel 11 whereby the arms of the lifting apparatus engage the surface of the lower wall portion 4 forming the double width channel 11.

The support members 33 are vertically extending and Iongitudinally spaced along selected top deck members whereby suitable tying material or arms of a lifting apparatus may pass through or enter the pallet from any of its sides. The bottom deck or support means 32 is formed of a plurality of multichanneled members which are vertically aligned with and longitudinally spaced along the selected top slats 31 in the top deck. It may be desirable to increase the height ofthe top deck above the floor, therefore, the bottom slats are positioned below the lower edge of the

side members

34 and 35 and have their upper row of wall portions engaging and supporting the lower edge wall of the

side members

34 and 35.

In the illustrated structure, the support members 33 and the members forming the bottom deck or support means 32 cooperate to form a plurality of columnar members 37 and the columnar members 37 adjacent the

side members

34 and 35 each have horizontally extending interior side members 38 having their upper edge wall engaging a lower surface of the top slats 31 and the lower edge channel thereof receiving one end of the multichanneled members forming the bottom support means 32.

Opposite ends of the side members 38 of the columnar members 37 adjacent the

side members

34 and 35 are received in one edge channel of the support members 33 and the edge wall at the other edge of the support members 33 therein is in engagement with the interior side of the

side members

34 and 35.

Intermediate columnar members 37 and the columnar members 37 adjacent the

side members

34 and 35 have opposite ends of the support members 33 received in the edge channels 7 and 8 of the top slats 31 and the multichanneled members forming the bottom support means 32.

When the various multichanneled members are assembled and suitably secured together, preferably by spot welding at the respective edge walls 5 and 6 thereof, the pallet 30 thus formed is particularly adapted for storing and transporting material or merchandise. The vertical space between the top deck 31 and the bottom support means 32 provides easy access for a fork lift or insertion of banding or other tying material used to secure the load thereon.

The number and arrangement of columnar members 37 may vary from the nine illustrated to as few as four arranged in two rows of two each, depending on the load to be supported and size of pallet desired. The longitudinal and lateral spacing of the columnar members 37 and the removed portions of the

side members

34 and 35 cooperate to permit the entrance from any side of the arms or prongs of a conventional fork lift (not shown) or the placing of suitable banding or tying material through the pallet 30 to secure a load thereon.

It is to be understood that while certain forms of this invention have been illustrated and described, it is not to be limited to the specific forms or arrangement of parts herein described and shown.
