Panel-mounted control station housing
First Claim
1. In a control station housing adapted for having electrical control apparatus mounted thereto comprising:
- a substantially vertically oriented panel having an opening therein;
said housing having upper and lower transverse grooves open outwardly of said housing for receiving respective upper and lower edges of said panel opening, a vertical dimension between an outer edge of said upper groove and a corresponding edge of said lower groove being greater than a vertical dimension of said opening and a vertical dimension between bottoms of said respective grooves being less than said vertical dimension of said opening, said housing being insertable into said opening to engage said lower groove over said lower edge permitting rotation of an upper surface of said housing through said opening to align said upper groove with said upper edge;
resilient means in said lower groove biasing said housing upwardly to effect engagement of said upper groove with said upper edge; and
means carried by said housing extendable into said lower groove within said panel opening preventing downward movement of said housing within said opening sufficient to permit disengagement between said upper groove and said upper edge.

Abstract
A molded cover control station having transverse upper and lower grooves spaced apart by a distance less than the vertical dimension of a panel opening has a resilient gasket positioned against a rear flange, the gasket having a resilient protrusion which is received within the lower groove. Insertion of the control station housing from the rear of the panel such that the lower edge of the panel opening engages the resilient protrusion within the lower groove enables the resilient protrusion to be compressed an amount sufficient to enable the upper end of the housing to be swung forwardly through the opening to align the upper groove with an upper edge of the panel opening. The resiliency of the protrusion within the lower groove biases the housing upwardly to effect engagement between the upper groove and upper edge of the panel opening, and a screw carried by the housing is turned inwardly to project into the lower groove just above the lower edge of the panel opening to bear the weight of the control station and prevent the protrusion from being compressed.

14. In a control station housing adapted for having electrical control apparatus mounted thereto comprising:
-
a substantially vertically oriented panel having an opening therein; said housing comprising a forwardly projecting body and a peripheral flange projecting outwardly from said body, upper and lower transverse grooves at a juncture of said body and said flange, said grooves being wider than the thickness of said panel and open upwardly and downwardly, respectively, a vertical dimension between an outer forward edge of said upper groove and a corresponding edge of said lower groove being greater than a vertical dimension of said panel opening, a vertical dimension between bottoms of said respective grooves being less than said vertical dimension of said panel opening, and said flange being larger than said panel opening for overlapping said panel around a periphery of said opening; a flat gasket of resilient material disposed against said flange, said gasket comprising a protrusion along a lower transverse leg, said protrusion extending into said lower groove; a screw carried by said housing advancable to extend into said lower groove; said housing being mounted to said panel by; (i) inserting a lower portion of said housing body through said panel opening; (ii) engaging said lower groove over a lower edge of said panel opening; (iii) pressing said housing downwardly for compressing said protrusion; (iv) pivoting an upper end of said housing body through said panel opening until said flange engages a rear surface of said panel with said gasket interposed said panel and said flange; (v) releasing downward pressure on said housing, thereby permitting said protrusion to restore to a non-compressed condition biasing said housing upwardly in said opening for effecting engagement of said upper groove with an upper edge of said panel opening; and (vi) advancing said screw into said lower groove, said screw extending transversely across said lower edge of said panel opening in interference therewith, preventing said housing from moving downwardly in said panel opening sufficiently to effect disengagement between said upper groove and said upper edge.
