Definitions
- the present invention relates to an arrangement for a hydraulic lifting table of the scissor type with two pairs of mutually 5J attached scissor arms, which at their ends are connected by means of pivots and rollers to a lower frame section and an upper table section, and are mutually and operatively connected to the pivotable connection, comprising a power transmission arrangement for raising and lowering the table section.
- the lifting capacity of the table is determined by the maximum pressure available from the power transmission arrangement.
- the power transmission arrangement is pivotally secured to the frame section and is so arranged, on the lifting table being raised, as to exert a separating effect on guide curves which, at the pivotal connection to the frame section, are operatively connected to it and to one of the scissor arms of each pair of 30." scissor arms.
- the scissor arm concerned Since a turning moment is generated at one end of the respective " - scissor arm in this design, the scissor arm concerned must be designed to withstand the resulting stress along its whole 35. ' length. This means that the lifting table, as a consequence of the dimensions of the scissor arm, is given a minimum height which is unacceptably large for many applications.
- the power transmission arrangement contains for each pair of scissor arms a hydraulic cylinder pivotally mounted at said connection; the pi-ston rod of the hydraulic cylinder is so arranged as to interact ,du ⁇ ' ng the whole of the raising and lowering movement of the lifting table via rollers with at least two guide curves arranged in conjunction with the common bearing shaft for the scissor arms and operatively connected to the respective scissor arm; and the mutually and operatively connected scissor arms, which are pivotally connected to the frame section, consist of a beam of 'U'—section open towards the top, in which the appropriate power transmission arrangement is arranged.
- Fig. 1 is a perspective view illustrating an embodiment of a lifting table in accordance with the present invention.
- Fig. 2 illustrates a plan view from the side showing details of the interaction of the power transmission arrangement with the guide curves.
- the designations 1a, 1b and 2a, 2b are used in Fig. 1 in respect of scissor arms connected together by means of shafts 1c, 2c for a hydraulic lifting table of the scissor type, which consists of a lower frame section 3 and an upper table section 4.
- the scissor arms 1a, 2a are mutually connected at their lower ends to a shaft 5 and are pivotally mounted about same relative to the frame section 3.
- the upper ends of the scissor arms 1b, 2b are pivotally mounted in the table section 4.
- rollers 6 of which those at the upper end of the scissor arm 2a and at the lower end of the scissor arm 2b are not shown in the drawing.
- the purpose of the rollers 6 is to facilitate the movement of the aforementioned ends of the scissor arms along the frame sections and table sections, 3 and 4.
- Each of the scissor arms 1a and 2a consists of a beam of 'U 1 —section open towards the top, in which there is arranged, pivotally mounted on the shaft 5, a hydraulic cylinder 7a and 7b for raising and lowering of the table section 4.
- Each of the scissor arms 1b and 2b is manufactured from two flat steel profiles connected together at their respective ends by means of cross— ieces.
- Three rollers 9a, 9b and 9c are arranged on a common shaft 10 at the outer end of the piston rod 8a of the hydraulic cylinder 7a.
- the roller 9b interacts with a guide curve 11b, which is operatively connected to the scissor arm 1b.
- the guide curves 11a and 11c constitute a linear gradient, and their primary function is to provide a moment arm, designated by 12 in Fig. 2, between the point of engagement of the roller 9b with the guide curve 11b and the common angle of pivoting 1c of the pair 1a, 1b of scissor arms.

Abstract
Un agencement, destiné à une table de levage hydraulique du type à ciseaux, comprend deux paires de bras de ciseaux (1a, 1b; 2a, 2b) fixées l'une à l'autre qui, à leurs extrémités, sont reliées au moyen de pivots et de cylindres à une section de structure inférieure (3) et à une section de table supérieure (4). Les bras des ciseaux (1a, 1b; 2a, 2b) sont reliés les uns aux autres et de façon fonctionnelle à une connexion pivotante (5) avec la section de structure (3). La table de levage comprend un agencement de transmission de force (7, 8, 9, 11) servant à soulever et à abaisser la section de table (4). La présente invention se caractérise par le fait que l'agencement de transmission de force (7, 8, 9, 11) comporte pour chaque paire de bras de ciseaux (1a, 1b; 2a, 2b) un vérin hydraulique (7a; 7b) monté de façon pivotante sur ladite connexion (5). La bielle (8a, 8b) du vérin est conçue de façon à agir en interaction par l'intermédiaire de cylindres (9a, 9b, 9c) avec des guides incurvés (11a, 11b, 11c) placés en conjonction avec l'arbre de portée commun (1c, 2c) des bras de ciseaux (1a, 1b; 2a, 2b) et reliés de façon fonctionnelle au bras de ciseaux respectif (1a, 1b; 2a, 2b).
