Abstract

A window protection apparatus on a working machine features a reel rotatably supported at an exterior of the operator cabin in a position proximate a top end of the window for rotation about a horizontal axis and a flexible window covering wound on the reel such that rotation of the reel in a first direction deploys a free end of the window covering from the reel, and rotation of the reel in an opposite second direction retracts the free end of the window covering back toward said reel. A retaining member is mounted at the exterior of the operator cabin in a position proximate a bottom end of the window, and a retaining element is attached to the window covering proximate the free end thereof for engagement with the retaining member to secure the window covering in a closed position spanning downwardly from the reel over the window.

Claims19

Dependent claims

In combination, a working machine and a window protection apparatus for an operator cabin of said working machine, the operator cabin of the working machine comprising a headlamp mounting arrangement that is defined above a window of said operator cabin at an exterior thereof and includes a predefined first pair of fastening features spaced apart from one another by a first distance and normally used for mounting of headlamps to the working machine above said window, wherein the window protection apparatus comprises:

a mount having a second pair of fastening features defined thereon that are spaced apart from one another by a second distance that matches the first distance for alignment of the second pair of fastening features on the mount with the first pair of fastening features on the working machine to enable fastening of the mount to the working machine via said aligned first and second pairs of fastening features to support the mount at the exterior of the operator cabin in a position above the window of said operator cabin;
a flexible window covering carried on the mount at position thereon that is arranged to reside at a spaced distance outwardly from the window of said operator cabin when said mount is supported at the exterior thereof, the flexible window covering being supported in a deployable and retractable manner for selective deployment of the window covering away from the mount and retraction of the window covering back toward the mount;
and
a retaining member arranged for mounting at the exterior of the operator cabin in a position proximate a bottom end of the window of said operator cabin;
a retaining element on the window covering proximate a free end thereof and engagable with the retaining member at a point thereon that is arranged to be spaced outwardly from the window of said operator cabin when said retaining member is mounted at the exterior of said operator cabin such that the window covering is secured in a closed position spanning over the window at a location spaced outwardly therefrom;
and
a tensioning mechanism operable to place the window covering in a tensioned state within the closed position at the location spaced outwardly from the window of the operator cabin, whereby the tensioned state of the covering member in the closed position is operable to prevent both an impact of the window of the operator cabin by a projectile and a deflection of said window covering against said window by said projectile.
