Sliding Staircase

       This article describes an economical tilt mechanism that
is operational from the front of a personal computer.

      Referring to the figure, within the cover structure 1 are
molded grooves 2 and step offs 3 on one side to act as teeth or
stops for a secondary leg 4.  The secondary leg has tenons 5 on the
top which slide within the provided grooves of the structure.
Secondary tenon 6 on the same side as the grooves serves as the male
counterpart to the stops.  When the weight of the PC is allowed on
the leg 4, the tenon 6 locates in one of the available grooves 3.
When the weight of the PC is off the leg 4, the leg falls to
the bottom of the provided grooves 2, disengaging the tenon 6 from
the stop 3.  Also, with the weight off, the leg 4, through gravity,
will slide toward the front "A" ofthe PC until weight is applied or
the leg contacts the table top 7.

      The movement of the leg towards the rear of the PC is manual.
The weight of the PC is relieved off the leg.  The leg moves to the
bottom of the grooves 2 and is not engaged.  A tenon 8, provided on
the leg 4, is used as a handle for moving the leg back.  As the
handle 8 is pulled in an up direction, the tenon on that side 5a goes
to the top of the groove 2a with the opposite side remaining at the
bottom of the groove, thus allowing the leg 4 to be manually slided
towards the rear of the PC. Movement of the leg forward is by tilting
the PC forward, thus allowing the leg t...
