Title (EN) SUPPORT LEG CONSTRUCTION
(FR) CONSTRUCTION D"UNE JAMBE SUPPORT
Abstract: front page image
(EN)In known support leg constructions of the type where the displacement of the support leg is carried out by means of a threaded rod, it is necessary that the pitch of the thread be not too steep as otherwise a rotation of one revolution of the rod requires too great a force. It is the object of the present invention to provide a support leg construction where the support leg is driven at a substantially greater rate when not loaded. The support leg construction of the invention is characterized in that the externally threaded rod (4; 4") has two portions (4a, 4b; 4a", 4b") with opposed pitch directions, one portion (4a;4a") being received in an internally threaded bore (12; 12") which is detachably non-rotatably connected with a holding means adapted to the supported means (2; 2") while the other portion (4b; 4b") carries an internally threaded element (6; 6"), to which one end of the support leg (7; 7") is pivotably adapted, and that a brace (10; 10") is pivotably attached with its ends to the support leg (7; 7") and to a means of attachment fixed relative to the supported means (11; 11").
(FR)Dans des constructions de jambe support connues du type dans lesquelles le deplacement de la jambe support est effectue au moyen d"une tige filetee, il est necessaire que le pas du filetage ne soit pas grand, pour eviter que la rotation d"un tour de la tige necessite un effort trop grand. La presente invention a pour objet une construction de jambe support dans laquelle la jambe support est actionnee a un taux substantiellement plus grand lorsqu"elle n"est pas chargee. La construction de la jambe support selon l"invention est caracterisee en ce que la tige filetee exterieurement (4; 4") possede deux parties (4a, 4b; 4a", 4b") avec des pas opposes, une partie (4a; 4a") etant recue dans un alesage filete interieurement (12; 12") lequel est relie de maniere detachable, non-rotative, a des moyens de retenue adaptes a la masse supportee (2; 2") tandis que l"autre partie (4b; 4b") porte un element filete interieurement (6; 6") auquel une extremite de la jambe support (7; 7") est adaptee de maniere pivotante, et une entretoise (10; 10") est reliee de maniere prive, tante par ses extremites a la jambe support (7; 7") et a un moyen de rattachement fixe au moyen supportes (11; 11").
