Abstract: A device for holding a laser measuring device for the vertical measurement of features of a subterranean structure. The device attaches to the opening of the structure by the use of extendable legs and magnets and holds a laser measuring tool with a mounting plate. The plate can slide along the device for the best line of site to the feature being measured.

Abstract: To permit adjustment of back parts of the chair, spring means, preferably in form of two U-bent spring rods, couple a lower back part (19) to an upper back part (21) and the effective spring length of the springs (23) is adjustable or changeable by moving a slider (27, 29), connected to one (21) of said back parts, for example via an attachment arrangement (23) of the spring elements themselves, longitudinally of the spring elements. Preferably, a positive stop arrangement to maintain an adjusted position is provided; or the adjusted position may be infinitely variable, for example by clamping the spring element in position by means of an eccentric. The ultimate deflection of the respective back parts can be limited by a stop (36) engaging a stop rod (47') which, simultaneously, can function as a slider guide, the stop rod (47), when springy itself, providing for a stiff terminal spring constant while permitting more easily yielding deflection before its engagement.
