Abstract

As shown in Fig. 1, a flat position and two angles of tilt are provided for on keypad 10 assembly by two bar-like folding legs, a short leg 12 and a long leg 14. These two legs nest together to provide a clean single leg support appearance. The legs are folded up or down manually and are held in proper position by plastic molded-in detents. The detenting is achieved by molded spring leaves in the keypad rear cover with matching recesses molded in the legs. As shown in Fig. 2, the tilt mechanism consists of three molded plastic snap-together parts. Short leg 12 is journaled to long leg 14. Legs 12 and 14 are then journaled to a carrier 16.

Dual Tilt Support Legs for Keypad

As shown in Fig. 1, a flat position and two angles of tilt are provided for on keypad 10 assembly by two bar-like folding legs, a short leg 12 and a long leg
14. These two legs nest together to provide a clean single leg support appearance. The legs are folded up or down manually and are held in proper position by plastic molded-in detents. The detenting is achieved by molded spring leaves in the keypad rear cover with matching recesses molded in the legs. As shown in Fig. 2, the tilt mechanism consists of three molded plastic snap-together parts. Short leg 12 is journaled to long leg 14. Legs 12 and 14 are then journaled to a carrier 16. To obtain the maximum tilt position, 12 and 14 are pivoted together to the down position, causing detent members 18 and 20 to flex torsion spring member 22 until detents 18 and 20 seat into recesses 24 and 26, respectively. To obtain the second tilt position, long leg 14 is pivoted to its up position with 18 engaged in recess 28, leaving short leg 12 in the down position with 20 engaged in 26. To obtain a flat down or no tilt position, short leg 12 is pivoted to its up position, with 20 engaged in recess 30.
