Housing mounting system
First Claim
1. A housing mounted on a top surface of a slotted metal frame, the housing comprising:
- a rigid base plate in contact with the top surface of said frame;
a first rigid mounting arm fixed with respect to said base plate, and extending from said base plate, such first mounting arm having;
a proximate portion extending in a direction substantially perpendicular to said base plate for insertion through a first slot in the frame with a pivotal insertion of the first mounting arm through the first slot;
an intermediate portion extending in a direction substantially parallel to said base plate and disposed adjacent a bottom surface of the frame opposite said top surface when the first mounting arm is pivoted to bring said base plate into contact with said top surface; and
a distal portion projecting from the intermediate portion into a second slot in the frame; and
a second rigid mounting arm fixed with respect to said first mounting arm and said base plate, said second mounting arm extending from said base plate opposite said first mounting arm, in contact with the top surface of said frame and adapted to be bolted to said frame.

Abstract
A mounting system for a housing and method of mounting a housing is provided where the housing is to be mounted to a slotted member in a secure and rigid fashion without loosening over time, particularly when exposed to high vibration environments. The mounting system includes a mounting arm of the housing which is to be inserted through a first slot and then pivoted so that a finger projection on the arm pivots up into a second slot formed in the frame member. The spacing of the first and second slots and the length of the arm and position of the finger projection thereon are such that when the finger is pivoted into the second slot, a cam surface on the finger will engage and slide against at least one of the walls of the slot so as to bias the arm against the frame member in the slots. In this manner, the arm is preloaded against subsequent movement even when subject to intense vibrations or other loosening forces. Other bolt fastener(s) are contemplated for use in mounting the housing by way of mounting flange(s) provided on the housing spaced from the arm or arms at predetermined positions therearound.

8. A low insertion force method for mounting a housing for a control device to a slotted frame, the method the step of comprising:
-
providing a first mounting arm on the housing extending outwardly therefrom and having first and second frame engaging portions; inserting the first mounting arm through a first slot in the frame; positioning the second frame engaging portion to be inserted in a second slot in the frame spaced from the first slot with the first frame engaging portion in the first slot; pivoting the housing towards the frame until the housing is flush against the frame and the second portion is inserted in the second slot; providing a second mounting arm on the housing extending outwardly therefrom opposite said first mounting arm; and fastening said second mounting arm to said frame.
