Debris Chute

Abstract

A gravity type debris chute formed by hanging a plurality of corner panels on corners of a structure having horizontal elements, a plurality of side panels and a door panel on the structure with horizontal structural elements so as to form a passage for debris to pass through, wherein each of the said corner panels is folded in the middle so as to form two symmetrical sides, the top of each of said corner panels folded to form a lip or a u fold so as to hang from a structural member, each of said side panels folded at the top to form a u fold or a lip capable of hanging from a horizontal structural member.

Claims

1. A gravity type debris chute formed by hanging a plurality of corner panels on corners of a structure having horizontal elements, a plurality of side panels and a door panel on the structure with horizontal structural elements so as to form a passage for debris to pass through, wherein each of the said corner panels is folded in the middle so as to form two symmetrical sides, the top of each of said corner panels folded to form a lip or a u fold so as to hang from a structural member, each of said side panels folded at the top to form a u fold or a lip capable of hanging from a horizontal structural member, the said door panel folded at the top end to form a u fold or a lip for hanging from a horizontal structural element, the said door panel further comprising a striker and a stiffener to prevent the door panel falling into the said passage through which debris passes through.

2. A debris chute as defined in claim 1 in which the corner plate is made of a single piece of metal plate.

3. A debris chute as defined in claim 2 where in the set of structural elements comprises an existing set of scaffolding members.

4. A debris chute as defined in claim 3 wherein the existing scaffolding members are placed horizontally to form an octagon for hanging four corner plates, three side plate and one door plate to form a debris chute passage with an octagonal cross section to form an enclosed passage or shaft for debris to pass through.

5. A debris chute as defined in claim 4, where a series of eight individuals panels make up an octagonal conveyor chute section such that the eight panels are connected to each other to form an enclosed shaft or passage in which individual panels are supported onto a structure such as existing scaffolding or a frame.

6. A debris chute as defined in claim 5, wherein a plurality of corner plates, side plates and door plates are hung from the horizontal members of an existing scaffolding structure and nested above each other to form a passage or shaft for debris to pass through.

7. A debris chute as defined in claim 6, wherein the angle between the two sides of the corner plate is anything from 90 degrees to 120 degrees.

8. A debris chute as defined in claim 7 wherein the middle fold of the corner plate in the corner plate is created in such a way as to prevent any interference with any vertical structural members of an existing scaffolding.

9. A debris chute as defined claim 8 wherein the four corner plates are attached to four corners of a horizontal structure.

10. A debris chute as defined in claim 9, wherein door panels are hung at different heights of a structure, corresponding to different floor levels of a building.

11. A debris chute as defined in claim 10 where the door panels are rotatable or hinged to a horizontal structural member.

12. A debris chute as defined in claim 10 where the door panel is hinged to a bottom horizontal structural member.

13. A debris panel of claim 10 where the door panel is hinged to a top horizontal structural member.

14. A debris chute of claim 10 where the door panel is supported by chains linked to a top horizontal structural member.

15. A debris chute as defined in claim 10 where a dust cover is positioned to prevent escape of any dust.

16. A debris chute as defined in claim 10 where it includes a warning system to indicate if any of the door panels are open.

17. A debris chute as defined in claim 10, where panels are made of any rigid material such as steel, plastic, aluminum or plywood.

Description

DETAIL DESCRIPTION OF THE INVENTION

[0013] The FIG. 1 as shown represents a corner panel of the present invention.

[0014] The FIG. 2 as shown represents a side panel of the present invention.

[0015] FIG. 3 as shown represents a door panel showing additional supporting channels on either side.

[0016] FIG. 4 represents a schematic chute of the present invention in fully assembled.

[0017] The invention is described below in detail with reference to the drawings.

[0018] The corner panel as shown in FIG. 1. As shown in FIG. 1, the corner panel is made by folding one piece in the middle as to form two symmetrical sides. The angle between the sides can be anything from about 90 degrees to 120 degrees.

[0019] The top of each side of the corner panel is folded at the top to form a lip or a u-fold (3,7) which can be used to hang the corner panel on an existing structural frame. The middle fold (5) is created to prevent any interference with an vertical support of an existing structural frame such as scaffolding.

[0020] FIG. 2 of the present invention illustrates a side panel of the present invention. It is folded at the top to form a U-fold or lip (3,7) which can be used for hanging on a horizontal element of an existing structural frame such as scaffolding.

[0021] FIG. 3 is an illustration of the door panel of the present invention. Similar to side panels of the present invention, the door panel is folded at the top end to form a u-fold or a lip (3,7) which can be used for hanging from a horizontal member of an existing structural frame such as a scaffolding. In addition, it has a striker (12), stiffener (11) with a bar and striker support, hinge (13) and a stop (10) to prevent the door panel from falling in. Item 19 is a spring-loaded catch.

[0022] FIG. 4 shows the present invention is use with side panels and door panels hung on horizontal members of an existing support structure such as a scaffolding. The corner panels (1) are attached at the four corners around the vertical frame (23) as shown. The side panels (8) are hung from the horizontal elements (21) on three sides as shown. On the third side, the door panel (9) is hinged at the bottom and chains (15) from the horizontal member immediately above. Flexible bellows (13) prevents any material falling through sides when the doors are open. A dust cover (16) can be positioned at any point of the vertical structure to prevent escape of any dust.
