Abstract
An adjustable support apparatus adapted primarily for antennas wherein most of the load is carried by pivotal rigid structural members and the drive members are subjected to a much smaller force. An embodiment is also described illustrating selferection principles.
Claims8
Support adjustment apparatus comprising, in combination:
- base means having a generally horizontal reference;
- load means to be supported and movable with respect to said base means and having a range of normal operating positions between 0.degree. and 90.degree. with respect to said base means;
- first and second rigid members pivotally connected to both said base means and the portion of said load means closest to said base means when said load means is in its range of normal operating positions;
- third rigid member means pivotally connected to said base means adjacent said first member means and pivotally connected to said load means adjacent said second member means to form, in combination with said load and base means, two substantially triangular and constant shape supporting configurations;
- fourth and fifth rigid member means pivotally connected to said base means and to said load means, in an area removed from said first and second members, to form, in combination with one of said load means and said base means, a substantially triangular and constant shape supporting configuration while said load means is in its range of normal operating positions;
- sixth and seventh member means pivotally connected to said base means and pivotally connected adjacent respectively said first and second members to form alterable triangular configurations between the associated members and one of said load means and said base means;
- and
- means for adjusting said sixth and seventh members to change the alterable triangular configurations and simultaneously change the operating position of said load means with respect to said base means.
