Abstract: Disclosed are front entry cabs, and power machines with front entry cabs, having a door that is moveable between opened and closed positions. In the opened position, the door is positioned within an operator compartment of the cab above the operator seat and below a top of the cab. A linkage system defines the travel path of the door between closed and opened positions. The linkage system is configured to minimize interference with operator visibility.

Abstract: A thermal shutter system comprises a plurality of elongate shutters (1). The shutters are mounted for rotation about the elongate direction thereof and are mounted for movement in a direction substantially perpendicular to the elongate direction. Each shutter is movable independently of the other shutter or shutters.

Abstract: An automated door system comprising a plurality of overlapping horizontal slats; wherein the plurality of overlapping slats are individually selectably removable. The plurality of overlapping horizontal slats further comprise an inward stair-step configuration. In addition, the system further comprises a control module, wherein the control module includes a touch screen interface. Furthermore, the system still further comprises a lifting system coupled to the plurality of slats and in communication with the control module; wherein the lifting system is configured to raise and lower the plurality of slats. The lifting system further comprises a rotor coupled to a stepped wheel and a pulley system configured to raise and lower the plurality of slats. The lifting system further comprises a plurality of tracks configured to guide the plurality of slats when raised and lowered.

Abstract: A window assembly for an operator's cab of a vehicle includes an upper window section which is movable from a closed position to an open, stored position in the roof of the cab. The window assembly includes first and second upper locking mechanism and first and second lower locking mechanism, and first and second release levers for simultaneously releasing the upper and lower locking mechanism. Current designs of removable windows require difficult and awkward operations to lock and unlock the latching mechanisms and for moving the window between closed and open positions. The subject window assembly incorporates simple and easily operated locking and unlocking mechanisms, as well as a convenient apparatus for moving and storing the opened window sections.

Abstract: A system for the opening and closing of a two-part front window for the cab of a vehicle, particularly an excavator, has an upper pane and a lower pane. The lower pane can be moved via rollers between guide rails into a raised opened position and into a lowered closed position, and both panes can be swivelled jointly into a lockable clear-view position arranged below the cab roof. The bottom pane, extending flush with respect to the top pane in the closed position, is held on the lower and upper guide rails in a supported manner.

Abstract: A window structure for closing an opening in an upright wall of a cab structure composed of upper and lower glass panels having adjoining horizontal edges. A horizontal hinge connects the upper edge of the upper panel to the cab structure so that the upper panel can swing inwardly to an upper horizontal position just under the roof of the cab. The lower panel may be mounted in the lower portion of the opening or on the rear face of the upper panel and when in the latter position, upper and lower panels may be swung upwardly against the roof of the cab and latched in this position. A gas-pressurized cylinder is used between the cab structure and the upper panel to aid in both raising the panels and to restrain the panels as they are lowered.

Abstract: Vertical and non-vertical collapsing panel closures for various applications are disclosed. The closure has reduced stacking height when collapsed and possesses a more energy efficient panel section guide roller system operating with a more economical and versatile upper and lower guide roller track arrangement. An insulated closure having an interior flush surface and an exterior rail and stile facade is achieved. A more simplified variable dynamic closure counterweighting system is provided.

Abstract: A vertically collapsing closure system comprising a door consisting of a plurality of rectangular panels in a side-by-side arrangement with each said panel being hingedly connected to each adjacent panel, and a means for operating the door to the full open position by causing the panels to rise vertically until at the height of the opening and then to fold or collapse into a compact terminal stack configuration and then to operate in reverse completing descent vertically once again fully closing the involved opening.
