Collapsible adjustable height table

A range limiter configured to be used with a telescoping leg, wherein the telescoping leg has a sleeve and a leg extension extending into a first end of the sleeve and the telescoping leg is slideable on a table top undersurface at a second end of the sleeve, the range limiter comprising:

• a two-way spring-loaded plunger assembly comprising:
• a light spring;
• a heavy spring;
• a plunger;
• the plunger disposable in the sleeve and extendable out of the sleeve at the second end of the sleeve;
• the heavy spring and the light spring of different forces and disposed in line with one another, positioned to act on the plunger in opposing directions;
• a first end of the heavy spring positioned to be engageable with the leg extension and an opposing, second end of the heavy spring positioned to be engageable with a first end of the plunger;
• the light spring engageable at a first end with the plunger first end;
• a stop component affixable to the undersurface;
• a second end of the plunger configured to be engageable with the stop component when the plunger is extended;
• wherein engagement by the leg extension with the heavy spring forces the plunger to extend out of the sleeve for engagement with the stop, and release of the leg extension from engagement with the heavy spring enables the light spring to expand, thereby retracting the plunger into the sleeve so it no longer engages with the stop.
