Mechanism for Multiple Retractabale Legs in an Enclosure

Enclosure 10 for a keyboard or other electronic device has two sets of different-length legs for adjusting a tilt angle with respect to a horizontal surface.

Solid leg 11 fits inside a hollow cavity in leg 12, which fits inside a cavity in leg 13. These nested legs fit into a recess 14 under enclosure 10. Knob 17 is inserted into opening 19 of cover 10.

Notches 18 of knob 17 align with corresponding splines 16 of leg 13 and pass through the holes of legs 11 and 12. The protrusions 23 on retainer 15 snap into openings 22 in notches 18 to secure knob 17 into cover 10. Notches 20 in legs 11-13 detent on protrusion 21.

The other end of enclosure 10 is similar.

Legs 11-13 are extended by twisting knobs 17 counterclockwise, so that notches 20' detent on ridge 21. The tilt angle of enclosure 21 may then be decreased by manually rotating the end of leg 13 clockwise, leaving legs 11, 12 extended. The angle may be further decreased by rotating the end of leg 12, leaving only leg 11 extended. The minimum angle is achieved by rotating leg 11 clockwise. Since legs 11, 12 do not contain teeth such as 16, they may be rotated independently of splined rod 15.
