The gap 30 is sized to receive a bundle of roofing shingles 6 therein and may have a width such as, by way of non-limiting example, in the range of 3 to 6.5 inches (75 mm to 165 mm). Proximate to the top edge 24 of each of the front and rear walls, 26 and 28 is included an entrance portion, 27 and 29, respectively, angled away from the gap 30 as illustrated to form a widened entry location to facilitate insertion of the bundle of roofing shingles 6. As illustrated in FIG. 3, the entrance portions 27 and 29 may comprise substantially planar members with an angle 25 to the front or rear walls 26 and 28. The angle 25 may be selected to be up to 30 degrees. Optionally, each of the entrance portions 27 and 29 may be formed of a radiused portion as illustrated in FIG. 4. The corners of the top edge 24 of each of the front and rear walls 26 and 28, may be radiused 23, so as to reduce the likelihood of catching on the shingles or other objects.

(13) The hook assembly 40 extends between top and bottom edges, 42 and 44, respectively, and between first and second side edges, 46 and 48, respectively. The hook assembly 40 includes a plate 50 having front and rear surfaces 52 and 54, respectively, with first and second hooks, 56 and 58, extending from the rear surface 54. The first hook 56 is positioned proximate to the top edge 42 and the second hook 58 is positioned proximate to the bottom edge 44. The first and second hooks, 56 and 58, include rung cavities 60 spaced apart to receive ladder rungs 4 therein. The hook assembly 40 is sized such that the first and second side edges 46 and 48 are positioned proximate to the side rails 2 of the ladder 8 when hung on the rungs 4. The first and second hooks 56 and 58 may be formed in a of a semi-spherical shape as illustrated, although it will be appreciated that other shapes may be useful, as well, such as segmented, semi-octagonal, square, rectangular or another arcuate shape having a cavity adapted to receive a ladder rung 4 therein. As illustrated in FIGS. 2 and 3, the first hook 56 is co-formed with the plate 50 and the second hook 58 is formed separated from the plate 50 and secured thereto. It will be appreciated that both hooks 56 and 58 may be co-formed with the plate 50 or secured thereto by means as are commonly known. As illustrated, the first and second hooks 56 and 58 extend between the first and second side edges 46 and 48. It will be appreciated that the hooks 56 and 58 may each be formed as a plurality of hooks with a plurality of hooks proximate to the top edge 42, such as, by way of non-limiting example, one hook proximate to the first side edge 46 and a second hook proximate to the second side edge 48, and a plurality of hooks proximate to the bottom edge 44, formed in the same manner, as illustrated in FIG. 5.

(14) The spacers 70 extend between first and second surfaces, 72 and 74, respectively and between top and bottom edges, 76 and 78, respectively and join the hook assembly 40 to the bracket 20. The first surface 72 of each spacer 70 is secured to the front surface 52 of the plate 50 and the second surface 74 of each spacer 70 is secured to the rear wall 28 of the bracket 20. The spacers 70 are positioned such that the top edge 76 is positioned below the top edge 42 of the hook assembly 40 and below the top edge 24 of the bracket 20, and the bottom edge 78 of each spacer 70 extends to proximate the bottom 22 of the bracket 20. The bracket 20 is positioned such that the top edge 24 extends above the top edge 42 of the hook assembly 20. There may be a plurality of spacers 70, such as, by way of non-limiting example, 4 spacers as illustrated in FIG. 2, although it will be appreciated that more or less spacers 70 may be useful, as well. Although the spacers 70 are illustrated as separate parts, it will be appreciated that the spacers 70 may be co-formed with the plate 50 or with the bracket 20. The distance between the first and second surfaces 72 and 74 is selected such that the second surface 74 extends beyond the side walls 2 of the ladder 8 when the hook assembly 40 is engaged on the rungs 4, such that the gap 30 of the bracket 20 does not intersect with the ladder 8, thereby allowing for items having a width greater than the width of the ladder to be received within the gap 30.

(15) The apparatus 10 may be formed using sheet metal, as is commonly known, with connections formed using methods that are commonly known, such as welding or adhesives. It will be appreciated that the apparatus 10 may also be formed with injection molded plastic material. Although only one of each of the first and second hook 56 and 58 are illustrated in FIGS. 1-3 it will be appreciated that more than one of each of the first and second hooks may be provided as illustrated in FIG. 5.

(16) Turning now to FIG. 6, a further embodiment of the apparatus 10 is illustrated with a step 80 extending from the rear surface 52 of the plate 50 opposite from the second hook 58. The step 80 provides the user with a means to climb the ladder 8 past the apparatus 10.

(17) Turning now to FIG. 7, a further embodiment of the apparatus 10 is illustrated with the first and second hooks 56 and 58 spaced apart such that the apparatus 10 extends over a plurality of ladder rungs 4, such as, by way of non-limiting example, three ladder rungs 4. A support 82 extends at an angle between the bottom 22 of the bracket 20 and the plate 50 proximate to the bottom edge 44. This configuration allows for heavier items, such as, by way of non-limiting example, sheets of plywood, to be retained within the bracket 20, providing support to the load which is distributed over a greater length of the ladder 8.

(18) Turning now to FIG. 8, a further embodiment of the apparatus 10 for use with a manual hoist system, as is commonly known, is illustrated. The apparatus 10 includes a hoist ring 84, as is commonly known, extending from the rear wall 28 of the bracket 20. Although the hoist ring 84 is illustrated as being co-formed with the rear wall 28, it will be appreciated that other lift attachment means may be used, such as, by way of non-limiting example, a standard hoist ring attached with a fastener. A hoist rope (not shown) is secured to the hoist ring 84 by means as are commonly known.

(19) A spacer 86 is secured to the rear wall 28 of the bracket 20 proximate to the top edge 24 and extends between distal ends 88. The distal ends 88 extend beyond the side edges of the bracket 20, with the length of the spacer 86 between distal ends 86 selected to be received between the ladder side rails 2 so as to maintain the apparatus 10 centered therebetween. The length of the spacer 86 may be such as, by way of non-limiting example, 16 inches (406 mm).

(20) A hook assembly 90 includes a plate 92 having front and rear surfaces 94 and 96, respectively, with a hook support 110 extending from the rear surface 96. The plate 92 extends from the bottom 22 of the rear wall 28 of the bracket 20 to a bottom edge 98 and between first and second side edges, 100 and 102, respectively. The plate 92 is selected such that the distance between the first and second side edges, 100 and 102, is less than the width of the bracket 20.

(21) The hook support 110 is extends from the rear surface 96 of the plate 92 proximate to the bottom edge 98. The hook support 110 extends between distal ends 112. The distal ends 112 extend beyond the first and second side edges 100 and 102 of the plate 92, with the length of the hook support 110 between distal ends 112 selected to be received between the ladder side rails 2. The length of the hook support 110 may be such as, by way of non-limiting example, 12 inches (305 mm). A retractable hook 114 is pivotably secured to each distal end 112 of the hook support 110. The retractable hooks 114 may be such as, by way of non-limiting example, rung locks, as are commonly known in the art.

(22) To utilize the apparatus 10 as illustrated in FIG. 8, a hoist rope 116 is attached to the hoist ring 84 by means as are commonly known. The hoist rope is extended over the top of the ladder 8 or a pulley 118 and back down to the user. When the user applies a downward force on the distal end of the hoist rope, the apparatus 10 is raised up the ladder 8 with the spacer 86 maintaining the apparatus centered between the rails 8. As the apparatus 10 is lifted, the retractable hooks 114 slide past the rungs 4, as is commonly known. When the upward force on the apparatus 10 is released, the retractable hooks engage upon a rung 4, as is commonly known in the art, and the apparatus 10 is retained in position.
