Abstract

Across the surface and around two opposite sides of a table top are looped two elastic hold down straps. A third elastic hold down strap is looped around these two straps and the other two sides of the table top. Lips grip an edge of the table top. The table top is slidably mounted on rails held parallel by two parallel supports each pivotally connected to ends of arms. The arms are pivotally connected at their other ends to a shaft. Upper ends of table legs are pivotally connected to the shaft. Interspaced between arms and legs on the shaft are spacers and a tube through which the shaft passes. When a cap nut is secured on one end of the shaft and a knob is screwed onto threads at the other end of the shaft, arms and legs are pressed together preventing them from pivoting around the shaft and locking the table top in a chosen position of height and inclination. Springs connecting arms and legs bias arms to rise to a vertical position when the knob is loosened.

first and second parallel slide rails;
a table top slidably connected to said first and second parallel slide rails by a plurality of brackets;
first and second parallel rail supports,
each of said rail supports having one end secured to said first slide rail and the other end pivotally connected to said second slide rail to form a frame;
parallel first and second single piece arms, each of said single piece arms having one end secured to said second slide rail and the other end pivotably and slidably connected to a shaft;
parallel first and second two piece jointed arms, each of said jointed arms having one end pivotally and slidably connected to opposite ends of said shaft, said first jointed arm having its other end pivotably connected to said first rail support, said second jointed arm having its other end pivotably connected to said second rail support;
a first and second leg, each leg being slidably and pivotally connected to opposite ends of said shaft;
parallel first and second leg mates, each of said leg mates being pivotally and slidably connected to opposite ends of said shaft;
a tube through which the shaft passes being secured to said first and second leg mates for holding them parallel to each other;
locking means on the shaft for locking said first and second single piece arms, said first and second jointed arms, said first and second legs and said first and second leg mate in a selected orientation relative to the shaft.
