Abstract

A composite chute for a commercial vehicle includes a metal frame, and a pair of plastic sheets. The metal frame assembly defines a longitudinal axis. The pair of plastic sheets extend along the longitudinal axis and positioned on either side of the metal frame assembly. The metal frame assembly is sandwiched between the pair of plastic sheets.

First claim

What is claimed is:

1 . A composite chute for a commercial vehicle, the composite chute comprising:
a metal frame assembly defining a longitudinal axis; and a pair of plastic sheets extending along the longitudinal axis and positioned on either side of the metal frame assembly, wherein the metal frame assembly is sandwiched between the pair of plastic sheets.

2 . The composite chute of claim 1 , wherein the pair of plastic sheets are bonded with each other with the metal frame assembly positioned between the pair of plastic sheets.

3 . The composite chute of claim 1 , wherein the metal frame assembly comprises:
a first structural member having an arcuate shape and positioned at a first end of the composite chute; a second structural member having an arcuate shape and positioned at a second end of the composite chute; and a plurality of elongated members extending between the first structural member and the second structural member along the longitudinal axis and fixedly coupled with the first structural member and the second structural member.

4 . The composite chute of claim 3 , wherein the pair of plastic sheets comprise a first plastic sheet and a second plastic sheet, wherein the first plastic sheet defines a concave surface of the composite chute, the concave surface configured to guide a slurry material along the composite chute.

5 . The composite chute of claim 4 , wherein the first plastic sheet is positioned on a first side of the metal frame assembly and the second plastic sheet is positioned on a second side of the metal frame assembly.

6 . The composite chute of claim 5 , wherein the second plastic sheet comprises a plurality of ribs extending in a longitudinal direction along the second plastic sheet, wherein each of the plurality of ribs define a channel configured to receive a corresponding one of the plurality of elongated members of the metal frame assembly.

7 . The composite chute of claim 1 , wherein the pair of plastic sheets are manufactured from a thermoplastic material.

8 . A concrete mixer vehicle comprising:
a chassis; a plurality of tractive elements coupled with the chassis; a mixer drum coupled with the chassis; and a composite chute configured to facilitate discharge of a slurry material from the mixer drum, the composite chute comprising:
a metal frame assembly defining a longitudinal axis; and
a pair of plastic sheets extending along the longitudinal axis and positioned on either side of the metal frame assembly, wherein the metal frame assembly is sandwiched between the pair of plastic sheets.

9 . The concrete mixer vehicle of claim 8 , wherein the pair of plastic sheets are bonded with each other with the metal frame assembly positioned between the pair of plastic sheets.

10 . The concrete mixer vehicle of claim 8 , wherein the metal frame assembly comprises:
a first structural member having an arcuate shape and positioned at a first end of the composite chute; a second structural member having an arcuate shape and positioned at a second end of the composite chute; and a plurality of elongated members extending between the first structural member and the second structural member along the longitudinal axis and fixedly coupled with the first structural member and the second structural member.

11 . The concrete mixer vehicle of claim 10 , wherein the pair of plastic sheets comprise a first plastic sheet and a second plastic sheet, wherein the first plastic sheet defines a concave surface of the composite chute, the concave surface configured to guide a slurry material along the composite chute.

12 . The concrete mixer vehicle of claim 11 , wherein the first plastic sheet is positioned on a first side of the metal frame assembly and the second plastic sheet is positioned on a second side of the metal frame assembly.

13 . The concrete mixer vehicle of claim 12 , wherein the second plastic sheet comprises a plurality of ribs extending in a longitudinal direction along the second plastic sheet, wherein each of the plurality of ribs define a channel configured to receive a corresponding one of the plurality of elongated members of the metal frame assembly.

14 . The concrete mixer vehicle of claim 8 , wherein the pair of plastic sheets are manufactured from a thermoplastic material.

15 . A composite chute for a concrete mixer assembly, the composite chute comprising:
a metal frame assembly; and a single plastic sheet positioned on a top side of the metal frame assembly.

16 . The composite chute of claim 15 , wherein the plastic sheets is bonded with the metal frame assembly.

17 . The composite chute of claim 15 , wherein the metal frame assembly comprises:
a first structural member having an arcuate shape and positioned at a first end of the composite chute; a second structural member having an arcuate shape and positioned at a second end of the composite chute; a plurality of elongated members extending between the first structural member and the second structural member in a longitudinal direction and fixedly coupled with the first structural member and the second structural member; and an intermediate structural member having an arcuate shape and positioned between the first end and the second end of the composite chute, the intermediate structural member fixedly coupled with each of the plurality of elongated members.

18 . The composite chute of claim 15 , wherein the plastic sheet defines a concave surface, the concave surface configured to guide a slurry material along the composite chute.

19 . The composite chute of claim 15 , wherein the metal frame assembly further comprises a pair of hooks positioned on the metal frame assembly proximate a first end of the composite chute.

20 . The composite chute of claim 19 , wherein the metal frame assembly further comprises a pair of coupling members positioned proximate a second end of the composite chute, the coupling members configured to interlock with a pair of hooks of an adjacent composite chute.
