Mechanical devices and structures

Abstract

A very stiff mounting structure comprises at least three pyramidally disposed rod-like members rigidly coupled together at one end and with their other ends rigidly coupled to a base either to stiffen the base and/or to mount a device such as a tool or instrument with respect to it. Three pyramidally disposed members (1a, 1b, 1c, FIG. 10) may be mounted on a tetrahedral base 22 or another three-dimensional base 22' (FIG. 11), or four such members on respective corners of a square pyramid, to form therewith a framework in which to mount, for example, a machine tool or measuring instrument, the base preferably being formed of similar rod-like members; or the base may be a plate or other structure of a separately existing machine or other entity.
