1. Tilt control apparatus comprising:
- a base;
a tiltable member; and
means for coupling together said tiltable member and said base, said coupling means including a hollow tubular member connected to said tiltable member, a torsion spring disposed within said hollow tubular member, a frictional sleeve enclosing said hollow tubular member, and a split tubular bracket enclosing said sleeve and said hollow tubular member, said split tubular bracket being connected to said base.

Abstract
A tilt control apparatus comprises a tiltable display assembly pivotally coupled to a base support member through a hinge structure including a torsion spring and friction producing means which operate to permit the display assembly to be tilted to and held securely at any desired angle.

11. Tilt control apparatus comprising:
-
a U-shaped base member having two legs, a tiltable member coupled to said base member, said tiltable member including a frame carrying a display panel, said frame having left and right parallel edges, the lower ends of said edges having laterally projecting hollow tubular members, a torsion spring disposed within each of said tubular members, a frictional sleeve enclosing each tubular member, and a split, tubular bracket enclosing each sleeve and its tubular member, the closure of each split bracket being adjusted to set the desired frictional engagement between each split bracket and the associated frictional sleeve, each tubular bracket being secured to one leg of said base member, one end of each spring engaging its tubular member and the opposite end engaging the associated tubular bracket so that, as said tiltable member is pivoted with respect to said base member by rotation of each tubular member within its tubular bracket, each spring winds up and generates a torque which opposes the pivoting of said tiltable member and permits the tiltable member to hold any desired angular position with respect to said base member.
