DETAILED DESCRIPTION

[0017] Referring first to FIGS. 1-4, a bucket backpack 10 is shown in exemplary form in order to teach how to make and use the claimed invention. Backpack 10 includes a rigid frame 20 having a vertical back-frame portion 22 and a horizontal bucket shelf 24 extending rearwardly from the back-frame, and a soft pack portion 30 removably attached to frame 20. Frame 20 in the illustrated example is made from welded tubular steel or aluminum members, although other materials including wood or suitably strong polymers or composites could be used, and other known joining techniques for the members making up the frame are possible, e.g. mechanical fasteners or molding in one-piece. Soft pack portion 30 is sewn from typical backpack materials such as nylon canvas.

[0018] Backpack 10 is used to secure and transport a common utility bucket B of known type, in particular a “five-gallon” type bucket with a lid L, although other types and sizes of buckets may be carried on the backpack.

[0019] Vertical back-frame 22 provides attachment points for soft pack portion 30, in the illustrated example with wraparound wings or sleeves of fabric such as 38 secured with snaps, rivets, pins, or Velcro® fastener into or around vertical back-frame members 22a and/or horizontal back-frame members 22b.

[0020] Horizontal bucket shelf 24 includes longitudinal brace members 24a extending rearwardly from vertical back-frame 22, and cross-members 24b as needed for strength. Shelf 24 further includes a circular retaining ring 24c comprising a substantially continuous raised circular wall or flange extending e.g. one or two inches upwardly from the horizontal shelf formed by brace members 22a and 22b. The diameter of ring 24c approximates and is sufficient to receive the diameter of the lower end of bucket B therein, with a close fit minimizing movement of the bucket in the ring. As best seen in FIGS. 1-3, ring 24c is spaced from the plane of back-frame 22 defined by members 22a, with an air gap 23 that ensures space is maintained between the bucket and a user's back. Ring 24c may include perforations or interruptions, slots, etc. for weight savings and drainage, or may even be a series of raised tabs in circumferential arrangement on the shelf corresponding to the outer circumference of the lower end of the bucket and sufficient to prevent the lower end of the bucket from shifting in any direction on the shelf.

[0021] Back-frame 22 further includes a telescoping handle assembly 26 extendable from the upper ends of tubular frame members 22a. Handle assembly 26 includes two spaced vertical members 26a nested telescopically in tubular back-frame members 22a, and a cross-handle 26b connecting the upper ends of vertical members 26a. Cross-handle 26b can be padded or rubberized for insulation, comfort, and grip. Handle assembly 26 can be locked into its stowed position and one or more raised positions using removable clevis pins 27 extending through aligned holes 126a formed through vertical tubular members 22a and 26a. Other locking means such as detent pins, expanding screw collars, and similar are also possible.

[0022] The close fit between bucket B and the interior of horizontal shelf ring 24c prevents any significant shifting of the bucket while walking. Bucket B can be further secured on the pack frame with one or more sets of straps 28 anchored to or wrapped around the frame and secured around the circumference of the bucket with buckles, Velcro® fastener, or similar known connectors 28b. Other possible securing means include rope, bungee cords, and the like.

[0023] Referring now to FIG. 5, soft pack portion 30 presents an essentially conventional backpack strap harness 34 and padded or ventilated fabric back panel 32 to the user, with the option of storage compartments or pockets if desired. A waistbelt 36 is desirable for additional carrying comfort and stability. Bucket B is supported rigidly and securely in rigid frame 20, without shifting, while the person is carrying the pack via the softer strap harness. Handle assembly 26 is positioned above the top of the bucket in the stowed position shown in FIG. 5, providing an attachment point for additional gear carried on top of the bucket, and keeping the handle clear for easy grasping if the bucket/pack combination is to be hand carried a short distance without donning the pack harness 34.

[0024] Also shown in FIG. 5 is the air gap 23 maintained between the non-breathable, rigid sidewall of the bucket B and the user's back. Air gap 23 keeps the user cool and prevents uncomfortable contact between the user's back and the bucket, eliminating the need for special cushioning so that soft pack back-panel portion 32 may be a lattice of straps or a simple panel of mesh or fabric for enhanced breathability.

[0025] Bucket B is easily removed from frame 20 for various purposes once a desired use location is reached, but can pick up dirt, water, snow, leaves, etc. when set on the ground. The open nature of bucket shelf 24 allows such debris to simply drain or fall off once the bucket is re-inserted in the frame and the frame is hefted onto the back for carrying, keeping the wearer and the soft pack portions clean and dry.

[0026] FIG. 5 also shows equipment holders or attachments 25 secured or attached to ring 24c, for example fabric pouches mounted on the ring or rigid holders such as b-rings or clips welded, molded, or mechanically secured to the material of the ring 24c. Holders 25 can be used to carry items such as fishing equipment or tools, for example, on the outside of the bucket shelf where they can be readily accessed.

[0027] Referring next to FIG. 6, the combination of bucket B and the rigid framework 20 of backpack 10 allows it to be used as a sturdy and comfortable chair, including a seatback created when handle assembly 26 is raised and locked in place. For additional comfort, a preferably removable backpad 29 may be secured to the inner face of the handle assembly 26, attached by Velcro® straps or similar. Backpad 29 may be stowed and carried somewhere on or in the soft pack portion 30, or on top of or inside bucket B if the backpad is not permanently attached to handle assembly 26. Lid L can also be provide with a cushion or pad (not shown, but known) for sitting, either removably or permanently attached to the lid. The rigid, L-shaped frame 20 with the brace members 24a and 24b in contact with the ground, and the large-diameter rigid ring 24c, ensures that the pack/bucket combination sits level on the ground for a stable seat.
