Abstract
The top of a table such as a drafting table which may be adjustable in its elevation, is counterbalanced by counterbalancing elements exerting an approximately constant balancing force. The counterbalancing elements comprise at least one leaf spring forming a bow inserted between the table top and a counter abutment below the table top so that the leaf spring or springs is biassed to form said bow, whereby the load on the bow has a tendency to cause a lateral flexure of the bow. The arrangement is such, that the downwardly directed force component caused by the weight of the table top and the pressure exerted by the bent leaf spring or springs, are directed opposite to each other.
Claims9
An apparatus for counterbalancing the top of a table, which table top is adjustable in its elevational position, comprising leaf spring means, first abutment means secured to said table top at its downwardly facing surface, second abutment means secured to said table below said table top, holding means loosely holding said leaf spring means relative to said abutment means, said first and second abutment means being spaced from each other so as to bend said leaf spring means to form a bow loaded for lateral flexure sufficiently to provide a support pressure effective in a direction substantially opposite to the downward force component exerted by the weight of said table top, whereby the table top is supported by a substantially constant force over a wide adjustment range.
