Abstract:
1. An adjustable telescoping arm comprising: an arm adapted to be raised, lowered or fixed; a release and adjustment mechanism; a scissors linkage formed of a first rectangular member having upper and lower ends, and a second rectangular member having upper and lower ends, said first and second rectangular members being pivotally connected to one another in a cross-like pattern; said upper end of said first rectangular member is pivotally connected to an arm assembly, and said lower end of said first rectangular member is slidably and pivotally connected to a linear actuator proximate a lower section of the housing, whereby horizontal movement of said linear actuator imparts vertical movement of said arm assembly, wherein said upper end of said second rectangular member is slidably and pivotally affixed to said arm assembly and said second end of said second rectangular member is pivotally affixed to a lower section of the housing, wherein said lower end of the first rectangular member is attached to a spring mechanism, said spring mechanism being biased in manner wherein extension of the spring urges said lower end of said first rectangular member towards said lower end of said second rectangular member, thereby imparting vertical movement of said arm assembly, wherein said lower end of said second rectangular member is slidably and pivotally attached to a second linear actuator and operatively connected to a second spring such that said second linear actuator and said second spring coact with said first linear actuator and first spring to horizontally move said lower end of said second rectangular member.
