DETAILED DESCRIPTION

(16) With reference now to the drawings, and in particular to FIGS. 1 through 14 thereof, a new debris chute embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

(17) As best illustrated in FIGS. 1 through 14, the debris chute assembly 10 generally comprises a scaffold 12 having a plurality of standards 14 and a plurality of ledgers 22. The standards 14 are spaced from each other and extend between a top end 16 and a bottom end 18. The standards 14 define a channel 20 between the standards 14. Each ledger 22 is coupled to and extends between a pair of associated standards 14 of the plurality of standards 14. The ledgers 22 are arranged in a plurality of levels 24 which are spaced from each other along the channel 20. In each level 24, the ledgers 22 form a closed loop around the channel 20.

(18) The scaffold 12 also includes a plurality of rosettes 26 and a plurality of wedge pins 28. Each rosette 26 is coupled to an associated standard 14 of the plurality of standards 14, and each wedge pin 28 extends through an associated ledger 22 of the plurality of ledgers 22 and an associated rosette 26 of the plurality of rosettes 26, thereby securing the associated ledger 22 to the associated rosette 26. It is contemplated that other embodiments may not have the scaffold 12 but may instead use vertical and horizontal members similar to the standards 14 and ledgers 22 of the scaffold 12. It is noted, however, that a particular advantage of including the scaffold 12 is that the scaffold 12 may be easily attached to further scaffolding 96 built for workers to navigate to perform various construction and repair activities and to access the debris chute assembly 10. The scaffold 12 of some embodiments may not have rosettes 26 and wedge pins 28, instead relying on alternative attachment means known to the art such as clamps.

(19) A plurality of wall members 30 is removably coupled to the scaffold 12. The wall members 30 are arranged in a plurality of tubular sections 32 which surround the channel 20. Each tubular section 32 is coupled to the ledgers 22 of an associated level 24 of the plurality of levels 24. Each wall member 30 of the plurality of wall members 30 comprises a wall panel 34, a hook 40, and a pair of wall flanges 42. As best seen in FIG. 13, Each wall panel 34 has an outer surface 34A, an inner surface 34B, an upper end 36, a lower end 37, and a pair of lateral edges 38 extending between the upper end 36 and lower end 37. The inner surfaces 34B of the wall panels 34 bound and define the channel 20 extending through debris chute assembly 10. The hook 40 is coupled to an upper end 36 of the wall panel 34 and a passageway 40A is defined between the hook 40 and outer surface 34A. Hook 40 is configured to receive an associated ledger 22 of the ledgers 22 and to enable the wall panel 34 to hang hangs onte from the associated ledger 22 of the ledgers 22 of the associated level 24. The hook 40 extends outwardly from the channel 20 and from the wall panel 34. The pair of wall flanges 42 is coupled to a pair of lateral edges 38 of the wall panel 34. The wall flanges 42 extend inwardly into the channel 20 from the wall panel 34, and each wall flange 42 of the pair of wall flanges 42 is oriented perpendicularly to the wall panel 34. The wall panel 34, hook 40, and wall flanges 42 are formed of a unitary sheet metal but may use other suitable materials. A lower end 44 of each tubular section 32 except a bottommost section 46 of the plurality of tubular sections 32 overlaps an upper end 36 of an associated adjacent tubular section 32 of the plurality of tubular sections 32, closing any gaps that would otherwise form between tubular sections 32.

(20) One of the wall members 30 of a topmost section 48 of the plurality of tubular sections 32 defines a hopper wall member 50, and other embodiments may include more hopper wall members 50. The wall panel 34 of the hopper wall member 50 defines an aperture 52 which extends through the wall panel 34. The hopper wall member 50 further comprises a door 54 to access the channel 20 through the aperture 52, a bar 62, and a prop 64. The door 54 is pivotally coupled to the wall panel 34 of the hopper wall member 50 and is movable between an open position 56 and a closed position 58 with respect to the aperture 52. The door 54 has a hooked upper edge 60 which extends around the bar 62, which is coupled to the wall panel 34. The bar 62 is oriented horizontally so that the door 54 is pivotable around the bar 62 and gravity biases the door 54 toward the closed position 58.

(21) The prop 64 is engageable with the door 54 to maintain the door 54 in the open position 56. The prop 64 is telescopically extendable and is mounted to the door 54 and the wall panel 34 of the hopper wall member 50. The prop 64 is lockable in an extended position to maintain the door 54 away from the wall panel 34 in the open position 56. A locking pin 66 or similar may be employed to lock the prop 64 in the extended position. It may be possible to secure the prop 64 in multiple positions such that the door 54 may be adjusted to various degrees of openness with respect to the aperture 52.

(22) A plurality of corner members 68 is removably coupled to the scaffold 12. Each corner member 68 is releasably mounted to an associated standard 14 of the plurality of standards 14 and is positioned between a pair of associated wall members 30 of the plurality of wall members 30. The corner members 68 act to close gaps made between wall members 30 of the same tubular section 32 and keep the wall members 30 from swinging inwardly into the channel 20 due to wind or other external forces.

(23) Each corner member 68 comprises a corner panel 70, an elongated member 78, and a plurality of couplers 84. The corner panel 70 engages the pair of associated wall members 30 to retain the panels of the pair of associated wall members 30 in a fixed position with respect to the scaffold 12. The corner panel 70 comprises a central portion 72 and a pair of flange portions 74. The pair of flange portions 74 is coupled to a pair of side edges 76 of the central portion 72, and each flange portion 74 engages the wall flange 42 of one of the pair of associated wall members 30. The flange portions 74 may form 45-degree angles with the central portion 72 to align with the wall flanges 42 of the associated wall members 30. The corner panel 70 comprises a unitary sheet metal but may use other suitable materials.

(24) The elongated member 78 is coupled to the corner panel 70 and is oriented parallel to the associated standard 14. The plurality of couplers 84 is coupled to the elongated member 78 and the associated standard 14, thereby securing the corner member 68 to the standard 14. A downward end 92 of each corner member 68 except a bottommost corner member (not shown) overlaps an upward end of an associated adjacent corner member 68 of the plurality of corner members 68, covering any gaps that would otherwise be formed between adjacent corner members 68.
