Definitions

  • the present invention relates generally to roof construction and replacement and more particularly to specialized pallets for transporting and delivering roofing materials, including roofing shingles onto peaked roofs.
  • roofing shingles are generally packaged in bundles that are stored and shipped on wooden pallets. Prior to the construction of new roofs or the replacement or reroofing of existing roofs roofing shingles need to be delivered onto the roofs. Pallets loaded with bundles of roofing shingles are transported by trucks from warehouses to the worksites and the individual shingle bundles are hauled up to the roofs by a conveyor or the pallets loaded with the shingle bundles are lifted up by a crane or fork lift. In the case of lifting pallets up to a roof by a crane or fork lift the individual bundles of shingles are unloaded from the pallets manually by workers and stacked on opposite sides of the roof ridge. The process of delivering shingles onto roofs is time consuming, labor intensive and exposes workers to unnecessary hazards.
  • U.S. Patent No. 7,874,451 to Bel discloses a container for use on planar surfaces having various slopes.
  • U.S. Patent Application Publication No. 2009/0044732 to MacKenzie discloses a pallet with a collapsible frame.
  • U.S. Patent No. 4,326,467 to Schleicher et al. discloses a pallet formed from a folded profiled metal sheet.
  • the present invention provides pallets that are designed and configured to straddle and rest on the ridge or peak of a roof which pallets can be used to store, transport and deliver roofing materials, including shingles onto roofs during construction or reroofing.
  • the present invention provides a pallet having a length and a width that is configured to rest alternatively on the peak of a roof and on a flat surface, the pallet comprising:
  • top deck for receiving and supporting materials to be delivered to a rooftop
  • legs extending downward from the base, wherein the legs have: angled bottom portions for that are angled so as to rest on opposite sides of the peak of a roof; and flat bottom portions for resting the pallet on a flat surface.
  • the present invention further provides a method of delivering objects onto the roof of a building which method comprises:
  • top deck for receiving and supporting materials to be delivered to a rooftop
  • legs extending downward from the base, wherein the legs have: angled bottom portions for that are angled so as to rest on opposite sides of the peak of a roof; and flat bottom portions for resting the pallet on a flat surface;

  • Figure 8 is a perspective view of a molded pallet according to one embodiment of the present invention.
  • the present invention provides pallets that are configured to receive materials, including roofing shingles, and support the materials on a flat surface or over the peak or ridge of a roof without the need for a separate conventional pallet.
  • the pallets of the present invention are configured to be transported fully loaded on trucks to work sites and be lifted fully loaded and placed onto the peak of ridge of a roof using fork lifts, cranes, etc. without any necessary adjustments required to rest on the peak of a roof.
  • the pallets are designed and configured to straddle the ridge or peak of a roof.
  • the pallets of the present invention can be manufactured as one- piece, molded structures that can be discarded after use or reused. In some embodiments that pallets can be molded from recyclable materials such as plastic materials for purposes of recycling of the materials. In other embodiments the pallets can be molded from materials such as particle board so that they can be discarded and burnt for disposal after use.
  • the pallets of the present invention can be configured to be used in conjunction with roofs having different pitches. Further the pallets can be provided with structural elements to receive the forks of fork lifts, lifting straps, chains, etc. for purposes of lifting the pallets with a fork lift, a crane, a pulley system, etc.
  • the pallets of the present invention can be sized to support and deliver a typical amount of 42 bundles of shingles in which there are 3 bundles per square (100 square feet).
  • the pallets can otherwise be sized to support and deliver a larger or smaller amount of shingles.
  • Figure 1 a perspective view of a pallet according to the present invention positioned on the peak or a roof.
  • pallet 1 is shown as straddling the peak or ridge of a roof 2 with opposite sides of the present resting on opposite sides of the roof.
  • reference numerals 3 and 4 will be used to identify the sides of the pallet 1
  • reference numeral 5 and 6 will be used to identify the ends of the pallet 1.
  • the pallet 1 has a top surface or deck 7 that has a generally rectangular shape.
  • Figure 1 depicts a load of material, which can represent bundles of shingles 8 on the pallet 1.
  • the deck 7 is supported by a base 9.
  • the base 9 includes a number of legs 10 that extend downward upon which legs 10 the pallet 1 can be supported on a roof 2 as shown in Fig. 1 or on any flat surface such as a truck bed or storage area.
  • the pallet 1 shown in Fig. 1 includes six legs 10, including four corner legs 11 and two middle legs 12 on each side. In other embodiments the pallets of the present invention can have only corner legs, or more than one middle leg on each side. In further embodiments the pallet can include a single leg on either side that extends along the entire length of or a substantial portion of the length of the pallet.
  • the pallet 1 can be provided with structural features that can be used to lift and move the pallet 1.
  • the pallet 1 can be provided with structural features that can be used to lift and move the pallet 1.
  • the pallet 1 can be provided with structural features that can be used to lift and move the pallet 1.
  • slots 13 provided in the base 9 beneath the deck 7 that can be configured to receive the forks of a fork lift.
  • different structures can be included for receiving lifting straps, hooks, chains, etc., including slots, eye bolts, hooks, pins, etc.
  • FIG. 2 is an end view that depicts alternative configurations of a pallet according to the present invention for different roof pitches. Roofs have different pitches based on factors that include geographical location, the type of roofing material used, walkability and aesthetics.
  • the pallets of the present invention are configured to be used in conjunction with roofs having different pitches.
  • the bottom of the palletsl are configured to be complementary to the peak or ridge of roofs to be received thereon.
  • the center of the bottom of the pallet 1 has an inverted V-shaped recess 14 formed in the base 9 as viewed from either end of the pallet which V-shaped recess 14 extends across the length of the pallet 1.
  • each of the legs 10 has an angled surface 15 at the bottom that extends upward toward the center of the bottom of the pallet 1.
  • the angle of the angled surfaces 15 of the legs 10 are linearly aligned with the sides of the V- shaped recess 14 for the different roof pitches that are drawn in broken lines in Fig. 2.
  • the bottom of the pallet 1 can have a recessed area 16 in which the inverted V-shaped recess 14 is formed.
  • the height of the legs 10 vary for roofs having different pitches with shorter legs being provided on pallets that are configured to be used with roofs having smaller pitches. Also as shown in Fig. 2 the width of the recessed area 16 measured between the inside surfaces of the legs 10 in the width direction of the pallets increases as the roof pitch decreases.
  • the bottoms of the legs 10 have flat surfaces 17 outward from the angled surfaces 15 which allow the pallets to rest on a flat surface for storage and transportation purposes.
  • Figure 3 is an end view of an end view of a pallet according to the present invention positioned on the peak of a roof.
  • the peak or ridge of the roof is received in the invented V-shaped recess 14 in the bottom of the pallets 1 and the angled surfaces 15 of the legs 10 rest flatly against the angled sloped surface of the roofs.
  • the weight of the pallets is distributed between the legs 10 and the bottom center of the pallets and the invented V- shaped recess 14 aligns/centers the position of the pallets and prevents the pallets from shifting sideways.
  • Figure 4 is a side view of the pallet of Fig. 3.
  • the pallet 1 shown in Fig. 4 includes corner legs 11 and one middle leg 12.
  • the legs 11 and 12 can be tapered as viewed from the sides of the pallet 1 to reduce the amount of material (and weight) used to make the pallets.
  • the legs 11 and 12 could have straight, parallel sides if desired.
  • the legs 11 and 12 can be similarly tapered as viewed from the ends (See Fig. 3) or have straight, parallel sides.
  • Figure 5 is a bottom view of the pallet of Fig. 3.
  • the V- shaped recess 14 is shown as extending across the length of the pallet 1.
  • the legs 10 are shown as having flat bottoms 17, angled sides 15 and tapered sides as discussed above.
  • the slots 13 that are provided to receive the forks of a fork life are drawn in broken lines in Fig. 5 since these slots are hidden within the pallet 1. As drawn in Fig. 5 the slots 13 extend through the width of the pallet 1.
