602596 Disclosed is a telescoping assembly which includes a first member attached to a spring button device and a second hollow member with an internal diameter which is larger than the external diameter of the first hollow member. The spring button device has a button end and a biasing component outwardly biasing the button end. The second hollow member includes at least two rows of longitudinally spaced apart apertures extending along the length of the member. The apertures in each row are offset with respect to apertures in a different row so that every aperture is located a different distance from a distal end of the second member. The button end is dimensioned to fit through any of the apertures in the second member when aligned therewith as a consequence of the force imparted by the biasing component to fix the relative position of the two members. |
