(13) Pallets are well known in the art, as a cost-effective means of stacking materials for storage, and moving the stacked materials from one place to another by transporting the pallets with a dedicated pallet transporter, for example forklifts or boom trucks. In the context of rooftop construction, pallets are used to store and transport shingles. Roofing shingles are generally packaged in bundles that are stored and shipped on pallets. The pallets may be initially stored at a warehouse, and then transported to the location where rooftop construction is occurring. 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 forklift. It must be noted that the pallets may also be used for accommodating terracotta tiles, slate tiles, rolls of membrane, etc.

(14) In the case of lifting pallets up to a roof by a crane or forklift the individual bundles of shingles are unloaded from the pallets manually by workers and resting the pallet on the rooftop. Traditionally, in cases where the rooftop has an inverted V shape, a pallet cannot be delivered to rest on the rooftop, since a pallet can only be resting on a substantially planar surface. Thus, the upper surface of the rooftop is typically not flat and it is not possible to rest the pallet on the rooftop in a secure manner.

(15) The roofing shingle delivery system 10 is designed to provide is a bracket system to sit directly on the peak of a peaked roof 12. In general terms, a pair of brackets 14 is disposed on the peaked roof of a house where roofing work is being done. It is within the terms of the embodiment that the pair of brackets 14 be interconnected, such as with a supporting brace connected at either end to the brackets. However, as illustrated, the pair of brackets 14 are independent from each other. The brackets 14, comprising the roofing shingle delivery system 10, are designed to support a traditional pallet 16 containing the roofing shingles 18, as shown in FIG. 3. As seen in FIG. 1, each of the brackets 14 are disposed by straddling the peak or ridge 20 of a roof 12 with opposite sides of the present resting on opposite sides 12a and 12b of the roof.

Alternatively, the brackets 104 may be made of a biodegradable material, such as for example a wood species easily biodegradable, a biodegradable plastic or a biodegradable cardboard.

(25) As illustrated in FIG. 4, each of the brackets 104 is comprised of an elongated upper member 112 designed to be disposed in a perpendicular relationship with respect to the ridgeline 110 of the roof 103. The brackets 104 include a first lower support brace 114 and a second lower support brace 116 which are disposed so as to rest directly against the surface of the opposite sides 103a and 103b, respectively, of the roof 103. The pallet 106 containing the roofing shingles 108 is temporarily disposed atop the elongated upper members 112 of each of the pair of brackets 104. The horizontal upper members 112 may have any appropriate dimensions to accommodate the pallet 106.

(26) Each upper member 112, as shown in FIGS. 5 and 6, is comprised of a C shaped channel constructed of an upper, flat platform surface 118 with walls 120 and 122 extending downward and generally perpendicular to the upper platform surface 118. A pair of struts 124 and 125 are permanently mounted at one end, 124a and 125a, such as by welding, to the inner bottom surface 128 of the upper member 112, and possibly to the inner surfaces of the walls 120 and 122, as can be understood with FIG. 6. The opposite end 124b and 125b of the first pair of struts 124 and 125 has a hollow cylindrical tube 126 and 127, respectively, secured thereto. The hollow cylindrical tubes 126 and 127 receive a bolt therethrough as discussed in more detail herein after.

(27) Each of the elongated upper members 112 has a pair of support members 130 and 132 which are secured at a first end 130a and 132a, respectively, to a first end 112a and the second end 112b, respectively, of the elongated upper members 112. Each of the pair support members 130 and 132 is constructed of an elongated strip 134 and 135, respectively, with a plurality of spaced holes 136 and 137 therethrough. A hollow cylindrical tube 138 and 140 are secured to the first end 130a and 132a, respectively, thereof. The hollow cylindrical tubes 138 and 140 receive a bolt 142 and 143, respectively, therethrough, and are secured in place with a nut 144 and 145, respectively, so that the support members 130 and 132 can pivot in the holes 146 and 147 through the walls 120 and 122, with respect to the first end 112a and the second end 112b, respectively, of the elongated upper members 112, as discussed in more detail herein after.
