Embodiment Construction

[0022] Referring now to the drawings, the following is a description of several embodiments or examples of the present invention in conjunction with the accompanying drawings, wherein like reference numerals are used to refer to like elements throughout, and wherein different features are not drawn to scale. Presently disclosed embodiments provide a motorized drive system and protective door system wherein an inner door is provided to resist outward pressure of the aperture by facing or abutting one or more interior surfaces of the aperture of the housing, and having An optional exterior panel for covering the housing bore from the outside, here by means of an external removable handle to operate the closure mechanism to initially retract the inner door to separate from the housing front panel, and then The inner door is moved upwardly at an angle, effectively disengaging the two sides of the aperture to allow the inner door to pivot to an open position and extend at least part...

Abstract

Protective door systems are presented for equipment enclosures in which an inner door is provided to resist outward opening pressures by facing or abutting one or more interior surfaces of an enclosure opening, with an optional outer panel covering the enclosure opening from the outside, where a closure mechanism is operated by an externally rotatable handle to initially back the inner door away from the enclosure front side and then to move the inner door upward at an angle to effectively clear two edges of the opening to allow pivoting of the inner door to an open position extending partially outside the enclosure opening.

Description

[0001] This application claims priority to U.S. Provisional Patent Application No. 60 / 853,238, filed October 21, 2006, and entitled "Protective Door System for Enclosures Against Internal High Pressure," which is hereby incorporated by reference. The entire contents of are incorporated by reference. technical field [0002] The invention relates generally to protective door systems, and more particularly to an electrical enclosure with a protective door system that is resistant to internal high voltages. Background technique [0003] Motor controllers are used with generators and other applications where electrical energy is converted for use in driving electric motors or other loads. Motor controllers and other electrical systems are typically housed within the housing to protect system components from dust or other contaminants, as well as to prevent operator exposure to the high voltages and currents present inside the housing. Electrical equipment typically includes tra...
