Abstract:
1. An enclosure for a gage, said enclosure comprising: a housing including a peripheral side wall having a first end and a second end and a central longitudinal axis, and a rim attached to said first end of said side wall by one or more mounting mechanisms, said rim including a opening, an inner surface and an outer surface, each said mounting mechanism including a first post and a second post extending between said first end of said side wall and said rim, an elongate radial slot extending between said first post and said second post defining a bottom surface, and a longitudinal slot extending between said first post and said second post, said longitudinal slot being in communication with said radial slot, said longitudinal slot defining an opening in said outer surface of said rim, said first post including an inclined ramp extending from said bottom surface of said mounting mechanism toward said outer surface of said rim, said second post including an overhang extending over and spaced apart from said bottom surface, each said mounting mechanism including a longitudinal passageway extending from said bottom surface of said mounting mechanism through said longitudinal slot, said passageway extending generally linearly and generally parallel to said central axis of said housing; and a cover including a mounting member adapted to be removably received within said opening of said housing, said mounting member including one or more outwardly extending mounting lugs, each said lug adapted to be received in a respective radial slot of a mounting mechanism; whereby said cover is adapted to be removed from said housing by rotating said cover in a rotational direction with respect to said housing about said central axis such that said mounting lugs are respectively located in said passageways whereupon each said mounting lug is adapted to pass through a respective passageway as said cover is moved away from said housing along said central axis or by rotating said cover in a rotational direction with respect to said housing about said central axis until said mounting lugs engage said ramps whereupon further rotational movement of said cover slides said lugs along said ramps such that said cover moves outwardly away from said housing along said central axis as said lugs slide along said ramps.
