Abstract

A cab for a refuse vehicle includes a cab body defining a first door opening and a second door opening, a first door positioned over the first door opening, and a second door positioned over the second door opening. Each of the first door and the second door includes a door panel and a peep window positioned proximate a lower end of the door panel. The peep window includes an interior windowpane and exterior windowpane. Portions of the interior windowpane and the exterior windowpane are vertically offset and horizontally offset.

First claim

The invention claimed is:

1 . A cab for a refuse vehicle, the cab comprising:
a cab body defining a first door opening and a second door opening; a first door positioned over the first door opening; and a second door positioned over the second door opening; wherein each of the first door and the second door includes:
a door panel; and
a peep window positioned proximate a lower end of the door panel, the peep window including an interior windowpane and exterior windowpane, wherein portions of the interior windowpane and the exterior windowpane are vertically offset and horizontally offset.

2 . The cab of claim 1 , wherein each of the first door and the second door includes:
an overhead window positioned proximate an upper end of the door panel; and a main window positioned beneath the overhead window.

3 . The cab of claim 1 , wherein the interior windowpane and the exterior windowpane have different shapes relative to one another.

4 . The cab of claim 1 , wherein at least a portion of a rear edge of the interior windowpane is positioned further rearward than at least a portion of the rear edge of the exterior windowpane.

5 . The cab of claim 1 , wherein at least a portion of an upper edge of the interior windowpane is positioned vertically above at least a portion of the upper edge of the exterior windowpane.

6 . The cab of claim 1 , wherein at least a portion of an upper edge of the exterior windowpane is positioned vertically above at least a portion of the upper edge of the interior windowpane.

7 . The cab of claim 1 , wherein at least a portion of a lower edge of the exterior windowpane is positioned vertically below at least a portion of the lower edge of the interior windowpane, at least a portion of a rear edge of the exterior windowpane is positioned further rearward than at least a portion of the rear edge of the interior windowpane, and at least a portion of a front edge of the exterior windowpane is positioned further forward than at least a portion of the front edge of the interior windowpane.

8 . The cab of claim 1 , wherein the cab body includes:
a front wall; a rear wall; a first sidewall extending between first ends of the front wall and the rear wall; and a second sidewall extending between opposing second ends of the front wall and the rear wall.

9 . The cab of claim 8 , wherein a first front corner is defined between the front wall and the first sidewall, wherein a second front corner is defined between the front wall and the second sidewall, and wherein at least the front wall, the first front corner, and the second front corner cooperatively define a windshield opening, further comprising a windshield received by the windshield opening, the windshield being configured as a single, continuous panel that extends across an entirety of the front wall and along at least the first front corner and the second front corner.

10 . The cab of claim 9 , wherein the windshield opening has a ledge extending along a peripheral edge thereof, wherein the ledge is recessed relative to the front wall, the first sidewall, and the second sidewall, wherein a periphery of the windshield interfaces with and extends along the ledge such that the windshield is substantially flush with the front wall, the first sidewall, and the second sidewall, and wherein the periphery of the windshield is bonded to the ledge without using a gasket.

11 . The cab of claim 8 , wherein a first rear corner is defined between the rear wall and the first sidewall, wherein the first sidewall defines a first rear opening proximate the first rear corner, wherein a second rear corner is defined between the rear wall and the second sidewall, and wherein the second sidewall defines a second rear opening proximate the second rear corner, further comprising a first rear window received by the first rear opening and a second rear window received by the second rear opening.

12 . The cab of claim 8 , wherein the front wall defines a lip and a recess positioned beneath and behind the lip, wherein the lip and the recess are positioned beneath a windshield of the cab, further comprising:
a bezel engaging the lip and covering the recess; and a windshield wiper assembly including:
a pair of actuators positioned within the recess and tucked behind the lip, each of the pair of actuators including a drive shaft extending through the front wall between the lip and the windshield; and
a pair of wipers, each of the pair of wipers coupled to the drive shaft of a respective one of the pair of actuators.

13 . The cab of claim 12 , wherein each of the pair of actuators includes a motor and a linkage assembly coupling the motor to the drive shaft, wherein the pair of actuators are configured to pivot the pair of wipers between a stowed position and an end of stroke position, and wherein, when in the stowed position, the pair of wipers overlap each other and are vertically aligned but offset from each other.

14 . The cab of claim 8 , further comprising a driver seat positioned within an interior of the cab, wherein:
a visibility assessment region defined about the cab has:
(a) a central zone (i) that extends 2 meters forward from the front wall and (ii) that extends laterally across a width of the cab;
(b) a first side zone (i) that extends 2 meters outward from the first sidewall, (ii) that extends 2 meters forward from the front wall, and (iii) that extends 1 meter rearward of the driver seat when the driver seat is in a position to accommodate an operator in a 5th percentile of height for women;
(c) a second side zone (i) that extends 4.5 meters outward from the second sidewall, (ii) that extends 2 meters forward from the front wall, and (iii) that extends 1 meter rearward of the driver seat when the driver seat is in the position to accommodate the operator in the 5th percentile of height for women; and
(d) a height of about 1.24 meters; and
a visibility profile for the visibility assessment region determined from the driver seat from an ocular point of the operator in the 5th percentile of height for women provides a visibility block of less than 27 cubic meters.

15 . A cab for a refuse vehicle, the cab comprising:
a front wall; a rear wall; a first sidewall extending between first ends of the front wall and the rear wall, wherein a first front corner is defined between the front wall and the first sidewall, wherein a first rear corner is defined between the rear wall and the first sidewall, and wherein the first sidewall defines a first door opening; a second sidewall extending between opposing second ends of the front wall and the rear wall, wherein a second front corner is defined between the front wall and the second sidewall, wherein a second rear corner is defined between the rear wall and the second sidewall, wherein the second sidewall defines a second door opening, wherein at least the front wall, the first front corner, and the second front corner cooperatively define a windshield opening; a windshield received by the windshield opening, the windshield being configured as a single, continuous panel that extends across an entirety of the front wall and along at least the first front corner and the second front corner; a first door positioned over the first door opening; and a second door positioned over the second door opening, wherein each of the first door and the second door includes:
a door panel; and
a peep window positioned beneath proximate a lower end of the door panel, the peep window including an interior windowpane and exterior windowpane, wherein one or more portions of the interi
