Abstract

Many cabinets containing electronic equipment are extremely heavy. Further, the inside spacing between a bottom wall support plate and electronic equipment installed in the cabinet may be limited. It is usual practice to install cabinet leveling studs after the cabinet has been completely assembled during installation. Some installations require the leveling pad to be rigidly attached to the bottom of the cabinet through blind holes. Accordingly, a leveling stud is needed which is easy to insert into a blind hole and distribute the tear out stresses evenly on the support plate in the event of side loads. This is achieved even with limited space inside the cabinet.

Leveling Supports

Many cabinets containing electronic equipment are extremely heavy. Further, the inside spacing between a bottom wall support plate and electronic equipment installed in the cabinet may be limited. It is usual practice to install cabinet leveling studs after the cabinet has been completely assembled during installation. Some installations require the leveling pad to be rigidly attached to the bottom of the cabinet through blind holes. Accordingly, a leveling stud is needed which is easy to insert into a blind hole and distribute the tear out stresses evenly on the support plate in the event of side loads. This is achieved even with limited space inside the cabinet.

The drawing shows the installation, and the installed position of a leveling stud. The head on the stud is sufficiently small to permit insertion through the aperture of a support plate with sufficient thickness and strength for cabinet loading. The free end of the stud has a screwdriver kerf. The lower surface of the leveling stud head is suitably roughened for increasing friction. The retainer ring has to be movable through the aperture but with a greater outside diameter than the diameter of the aperture, and is split to form a single-turn helix for facilitating entry into the cabinet. The edges of the ring are shaped to bind with the support plate and the lower surface of the head.

It is preferred that the material of the retainer ring be malleable for permitting deformations beyond the elastic limit without rupture. The fastening nut threadingly engaged onto the leveling stud has an upstanding pilot or shoulder adapted to fit into th...
