[0047] While various embodiments are amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the claimed inventions to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter as defined by the claims.

DETAILED DESCRIPTION OF THE DRAWINGS

[0048] The preferred embodiment for the improved ladder bucket is a main body constructed of a single piece of polypropylene injection molded to provide the intricate detailing and varying thickness of the bucket with nylon latch components and steel screws and springs. However, other embodiments may be made of any materials or formed by any methods known in the art. The bucket of the present invention is intended for use with multi-position ladders without a top cap.

[0049] A typical prior-art multi-position ladder in the closed or stored orientation incorporating the ladder bucket of the present invention is disclosed FIGS. 10-17. A multi-position ladder 700 will conventionally include four inner rails 730 connected in pairs by a hinge 760 that is adjustable via a hinge lock 770 that allows each pair of outer rails 730 to rotate and vary the angle between the inner rails 730. Adjustably slidable to each inner rail 730 is an outer rail 720 for which an extension lock 780 allows the outer rails 720 to slide along the inner rails 730 to adjust the overall height of the ladder 700. Between the pairs of outer rails 720 are outer rail rungs 740 preferably attached to the outer faces of the outer rails 720 and between the pairs of inner rails 730 are inner rail rungs 750 that preferably are within the profile of the inner rails 730. This arrangement allows each side of the ladder 700 to be independently adjustable in length for varied uses (such as on stairs). Other features that are commonly found on multi-position ladders include a foot 790 at the end of each outer rail 720 and inner rail to provide better traction and protect surfaces on which the ladder 700 is used.

[0050] A multi-position ladder bucket 100 in accordance with the present invention is illustrated in detail by FIGS. 1-9. The bucket 100 has a front wall 120, a rear wall 130, a right side wall 140, a left side wall 150 and a bottom 110 forming a bucket interior volume 105. The top of the front wall 120, rear wall 130, right side wall 140, and left side wall 150 define a bucket top surface 115 while the outer face of the bottom 110 defines a bucket bottom outer surface 170. The bucket 100 preferably includes four legs 180 at the corners of the bucket 100, each having a leg bottom surface 185. The legs provide lower clearance for the bucket latch 220 when resting on a planar surface. The bucket top surface 115 and leg bottom surface 185 define a bucket depth 190.

[0051] Along the upper edge of the top of the front wall 120, rear wall 130, right side wall 140, and left side wall 150 is formed a bucket lip 160 that provides an area to house the bucket latch mechanism 200 both strength and rigidity to the upper portion of the bucket 100 as well as a gripping area around the exterior of the bucket 100. Bucket lip ribs 165 span the interior of the bucket lip 160 for strength and stability of the lip 160. The bucket 100 may include right side wall inset 145 and left side wall inset 155 to allow clearance past the interior part of the hinge button 770 when in bucket 100 is in the use orientation (FIGS. 18-25), if necessary.

[0052] An embodiment of the present invention includes can ridges 107 that are sized for accommodating standard sized paint cans and aid in keeping paint cans from moving while using the multi-position ladder 700. The bucket top surface 115 may include tool orifices 102 that allow tools, hardware, or other materials to be stored in the bucket 100 when in use.

[0053] The bucket 100 includes two bucket latch mechanisms 220 that hold the bucket 100 on the ladder 700 while being used (use orientation) and while being stored (stored orientation). The preferred embodiment includes one latch mechanism 200 housed in the lip 160 of the front wall 120 and one latch mechanism 200 housed in the lip 160 of the rear wall 120. Preferably the latch mechanisms 200 identical and, along with the bucket 100 being symmetrical, allows for attachment of the bucket 100 to the ladder regardless of orientation.

[0054] Each latch mechanism 200 includes a latch button 210 that is pressed to disengage the bucket 100 from either the use or stored orientations. The latch button 210 is exposed through a front wall button orifice 125 in the front wall 120 or a rear wall button orifice 130 in the rear wall to allow the bucket latch 220 to be conveniently activated. Preferably, each latch button 210 is also exposed throw a bucket top surface button orifice 117. The latch button 210 may include button ridges 215 that provide grip for activating and tactile response for the buttons 210. The bucket latch mechanism 200 may be mounted to the bucket 100 by any means known in the art. The preferred embodiment uses steel screws (see, FIG. 9) to mount the latch mechanism 200.

[0055] The latch button 210 is operably connected to the bucket latch 220, which includes bucket latch storage clamp 230 and a bucket latch use clamp 240. As best seen in FIG. 5, each latch mechanism 200 includes a spring 250 that biases the latch mechanism 200 to a locked position. Pressing on the latch button 210 from the inside of the bucket 100 causes the latch 220 to slide (move horizontally) out from the locked position. When the latch button 210 is released, the latch spring 250 forces the latch 220 to move horizontally back to the locked position.

[0056] FIGS. 10-17 illustrate ladder bucket 100 of the present invention in the stored orientation on a multi-position ladder 700 in its folded orientation. These figures show storage of the bucket 100 between an uppermost ladder inner rail rung 751 and an inner rail adjacent rung 752. However, because multi-position ladders are manufactured with identical rung spacing, the bucket 100 may be stored between any pair of adjacent inner rail rungs 750. With this configuration, each bucket latch storage clamp 230 attaches around a part of two adjacent inner rail rungs 750 to hold the bucket 100 in place (see, FIG. 17). The preferred embodiment has the bucket 100 dimensioned to that the bucket top surface 115 is pressed against the inner rail opposite rung 755 and inner rail opposite adjacent rung 757 to further lock the bucket 100 in the stored orientation.

[0057] Placing the bucket 100 into the stored orientation can be accomplished by pressing the latch buttons 210 to slide the bucket latches 220 outward, placing the bucket 100 in position abutting the uppermost ladder inner rail rung 751 and the ladder inner rail adjacent rung 752 and then releasing the latch buttons 210. Alternatively, the bucket latch storage clamp outer face 235 and latch inner surface 225 are angled to allow the bucket 200 to be pressed against the uppermost ladder inner rail rung 751 and the ladder inner rail adjacent rung 752, which will force the bucket latch 220 to move horizontally outward without having to press the latch buttons 210. Note that releasing the bucket 100 cannot be done in the same way and requires pressing of the bucket latch buttons 210.

[0058] As best seen in FIG. 17, the combined rail depth 705 of the multi-position ladder 700 in this orientation is larger than the bucket depth 190 and is positioned so that neither the bucket top surface 115 nor the bucket leg bottom surface 185 extends beyond the rails 720, 730 (see, FIG.

[0059] 15). This not only prevents the bucket 100 from being inadvertently dislodged from the ladder 700 when stored, but also allows the outer rail rungs 740 to be used while the bucket 100 is in the stored position. Preferably, the bucket 100 is stored between the uppermost two or three inner rail rungs 750 to allow use of the ladder 700 with the inner rails 730 in longest extension.

[0060] FIGS. 18-25 illustrate ladder bucket 100 of the present invention in the use orientation on a multi-position ladder 700 in its A-frame orientation. In the use orientation, the bucket 100 is locked via the bucket latch use clamps 240 to the two uppermost ladder inner rail rungs 751 (top inner rung on each pair of inner rails 730 on each side of hinges 760). As best seen in FIG. 25, bucket latch clamps 240 hook the outer portion of their respective uppermost inner rail rungs 751 to secure the bucket 100 in place. Preferably the top of each uppermost inner rail rungs 751 when the ladder 700 is in the A-frame orientation is parallel to the bucket bottom outer surface 170 to provide optimum support for the bucket 100.

[0061] A preferred embodiment also includes the bucket latch use clamp outer face 245 having the same angle and being coplanar with the bucket leg inside lower chamfer 187. This arrangement will allow the bucket 100 to be pressed down onto the two uppermost inner rail rungs 751 without having to press the bucket latch button 210 to cause the bucket latches 220 to slide out horizontally and allow the bucket 100 to drop into place with the bucket bottom outer surface 170 abutting the top of each rail rung 751. Once the bucket is 100 in its proper use orientation, the latch springs 250 will bias the bucket latches 220 back to its locked position. Note that releasing the bucket 100 cannot be done in the same way and requires pressing of the bucket latch buttons 210.

[0062] Another preferred embodiment includes sizing the lips 160 of the front wall 120 and rear wall 130 such that they extend to either abutting or nearly abutting the top of their respective uppermost ladder outer rail rungs 745 to provide additional support against movement. Likewise, it is preferable that the bucket leg inside upper chamfers 188 (see, FIG. 5) are sized and configured to abut the innermost part of the top of their respective uppermost ladder inner rail rungs 751 to hold the bucket 100 in place in conjunction with the bucket latch use clamps 240.

[0063] FIGS. 19-33 illustrate ladder bucket 100 of the present invention in its stored orientation on a multi-position ladder 700 in its A-frame orientation. As best seen in FIG. 33, the furthest extending portion toward the outside of the ladder 700 is the bucket leg bottom surface 185. The disclosed arrangement keeps the bucket 100 stored within the outside profile of the outer rail 720, allowing full access to all ladder outer rail rungs 740, 745. This configuration also allows the multi-position ladder 700 to be used in its extension orientation (not illustrated) with the ladder bucket 100 in its stored orientation.
