Abstract: A positionable mount is demonstrated as a headgear implement-mount (28) supporting an eyewear front (30) through a resilient appendage (68). The implement-mount includes a friction surface (50) cooperating with a headed stud (52) to establish a constraint-dimension (62). The appendage is formed with an edged-channel cross section and includes an elongated slot (76) for receiving the implement-mount headed stud. In engaging the implement-mount, the appendage cross section is torsionally, deformably constricted in a manner creating resiliently biased friction between the appendage edges (72) and the friction surface, thereby holding the eyewear implement in a selected position relative to the headgear. Because the appendage with implement-mount engagement is resiliently biased, the implement position may be hand adjusted. The appendage with implement-mount engagement may be influenced by a pair of hand operators (100).

Abstract: A tiltable turntable for supporting a display monitor, for example, has a support base, a monitor base, and a post of a substantially H-shaped cross section by which the support base and the monitor base are resiliently coupled to each other for relative tilting and rotational movement. The support base has two spaced stoppers. To assemble the tiltable turntable, the support base and the monitor base are sandwiched by the post, and the support base is turned with respect to the monitor base until a retaining member of the post rides over an inclined surface of one of the stoppers. When the retaining member of the post is positioned between the stoppers, the post is retained between the stoppers against dislodgment from the support base and limits the range of relative rotational movement between the support base and the monitor base. The support base and the monitor base are resiliently held together by the retaining member of the post.

Abstract: Disclosed is a tilt-swivel base for a CRT display terminal. The base allows the CRT terminal to be readily swiveled around a vertical axis and tilted forward or backward around a horizontal axis or positioned with a combination of both movements. The cradle of the base may be placed within a recess formed in a horizontal supporting surface and thereby confine the base within the recess.
