Hi tec swivel and slide

A swivel and slide assembly, comprising:

• a slide base that includes a first longitudinal sliding section;
• a first swivel base that includes a second longitudinal sliding section which is dimensioned to provide, in conjunction with said first longitudinal sliding section, guided longitudinal sliding between said first swivel base and slide base;
• and
• a second swivel base positioned radially inward of said first swivel base, and said assembly further comprising a lock plate which is supported on said slide base, said lock plate including a series of holes spaced along the longitudinal direction, and said second swivel base including a centrally positioned pivot post, and said assembly further comprising a handle in mechanical communication with said lock plate and positioned for conveying a motion in said lock plate upon handle repositioning such that said lock plate is able to assume a free slide position and a slide lock position, and said pivot post extends through one of said holes in said lock plate when said lock plate is in said slide lock position and said lock plate is clear of said pivot post when in the free slide position.

A swivel and slide assembly, comprising:

• a slide base that includes a first longitudinal sliding section;
• a first swivel base that includes a second longitudinal sliding section which is dimensioned to provide, in conjunction with said first longitudinal sliding section, guided longitudinal sliding between said first swivel base and slide base;
• and
• a second swivel base positioned radially inward of said first swivel base, wherein said second swivel base includes a generally cylindrical shell with a notch formed in one side thereof, and said shell including a flanged extension at one edge of said notch and said second swivel base further including a base member extending off said shell adjacent an opposite edge of said notch, and said assembly further comprising a tube lock screw having a first hooked end designed for engagement with said flanged extension and a threaded opposite end secured to an adjustment member which is pivotably supported on said base member at a first pivot location, and said assembly further comprising a tube handle pivotably secured to said base member at said first pivot location and also pivotably secured to said adjustment member at a second pivot location with the two pivot locations being in an off-center relationship to provide an over the center locking arrangement.

A swivel and side assembly, comprising:

• a slide base that includes a first longitudinal sliding component;
• a first swivel base that includes a second longitudinal sliding component which is dimensioned to provide, in conjunction with said first longitudinal sliding component, guided longitudinal sliding between said first swivel base and slide base;
• a second swivel base which supports said first swivel base such that said first swivel base is free to rotate with respect to said second swivel base,
• a first locking mechanism for locking said first and second swivel bases to preclude relative rotation therebetween;
• a second locking mechanism supported by said slide base for preventing relative sliding action between said slide base and second swivel base and said second swivel base including, at a central position thereof, a central pivot post which provides both a central pivot location with respect to said first swivel base and a catch for said second locking mechanism.
