Abstract

A boom hose apparatus for a material collection vehicle includes a telescoping boom assembly and a hose assembly supported by the boom assembly. The boom assembly includes a plurality of telescoping conduits. A flexible hose is received through the telescoping conduits and can slidably extend from, or retract into, the conduits independently from the telescoping of the conduits.

First claim

What is claimed is:

1. A flexible hose for a boom hose apparatus, the boom hose apparatus including a telescoping boom assembly and a hose assembly supported by the telescoping boom assembly, the hose assembly including a first conduit and a second conduit telescopically movable relative to the first conduit, the flexible hose slidably moveable through the second conduit; the flexible hose comprising:
a rearward end being in fluid communication with a collection tank;
a forward end opposite to the rearward end and extending out from the second conduit; and
a hose end stopper secured to the rearward end and engageable with a front end of the second conduit to limit movement of the flexible hose relative to the second conduit.

2. The flexible hose of claim 1 , further comprising:
a coupling element arranged at the forward end of the flexible hose and configured to attach one or more accessories.

3. A flexible hose for a boom hose apparatus, the boom hose apparatus including a telescoping boom assembly and a hose assembly supported by the telescoping boom assembly, the hose assembly including a first conduit and a second conduit telescopically movable relative to the first conduit, the flexible hose slidably moveable through the second conduit; the flexible hose comprising:
a rearward end being in fluid communication with a collection tank;
a forward end opposite to the rearward end and extending out from the second conduit;
a hose end stopper secured to the rearward end and engageable with a front end of the second conduit to limit movement of the flexible hose relative to the second conduit;
the second conduit having a conduit inner diameter and a neck portion having a neck inner diameter, the neck inner diameter being smaller than the conduit inner diameter,
the hose end stopper including a head portion and a hose fit portion fitted at the rearward end of the flexible hose; and
the head portion having an external diameter larger than an outer diameter of the flexible hose, the external diameter of the head portion being smaller than the conduit inner diameter of the second conduit and greater than the neck inner diameter of the second conduit.
