Abstract

The top plate of the tripod is fitted with a gripping face (4,5) and a spirit level (7). The gripping face is used to fix a measuring apparatus, e.g. a theodolite, telescope, camera etc. The tripod permits the measuring instruments are to be kept in place horizontally and vertically with an accuracy of one micron, and is capable of supporting appts. The gripping face (4,5) can be used to hold five to six metre long poles vertically, such as those used by surveyors. The graduated telescopic feet are clamped by an interior eccentric device. They are articulated around an axle, and their swivelling movement is limited by a stop.

Description

La présente invention concerne un trépied télescopique d'une stabilité et d'un réglage horizontal trés préçis au IOéme de micron convenant partiulièrement aux Géomdtres,aux Cinéastes etc.. .Ce trépied est étudié pour servir de base à des tubes ou poteaux devant être maintenus provisoirement et rigoureusement à la verticale. Le serrage de ces tubes s'effectue au moyen d'une mâchoire placée au sommet du trépied. Le blocage des tubes coulissantset réglés à la hauteur désirée est pratiqué au moyen d'un excentré intérieur commandé en tournant le tube supérieur, un manchon molleté intercalé dans le développé d'un ou des tubes, permet le réglage horizontal au micron prés. The present invention relates to a telescopic tripod with stability and horizontal adjustment very precise to the micron IOme particularly suitable for Geomdtres, Filmmakers etc. This tripod is designed to serve as the basis for tubes or posts to be maintained temporarily and rigorously vertically. The clamping of these tubes is carried out by means of a jaw placed at the top of the tripod. The locking of the sliding and adjusted tubes at the desired height is practiced by means of an internal offset controlled by turning the upper tube, a soft sleeve inserted in the press of one or more tubes, allows horizontal adjustment to the nearest micron.

Ce trépied convient aux travaux Publics, aux Géométres, aux
Cinéastes ou autres fonctions pour la fixation des appareils ZThEodolites , lunettes de visée, tachymêtre,etc...par exemple une perche de cinq à six mètres devant être maintenue provisoirement verticalement avec une grande précision.This tripod is suitable for public works, surveyors,
Filmmakers or other functions for fixing ZThEodolites cameras, riflescopes, tachometer, etc ... for example a pole of five to six meters which must be temporarily held vertically with great precision.

En (I4) intérieurement à son extrémité supérieure i6Xerieure,tandis que l'autre partie du tube (9) inférieure est vissée également à ce manchon (II) étant intercalé entre ces deux parties. En (I9) embout final reposant sur le sol. FIG. 5 - represents in section a tube (9) in two parts, the upper part of which is fixed in (IO). A sleeve (II) has been screwed. At (I4) internally at its upper end i6Xerieure, while the other part of the lower tube (9) is also screwed to this sleeve (II) being interposed between these two parts. In (I9) end piece resting on the ground.

I1 est bien entendu qu'en tournant le manchon molleté (II) on allonge ou on raccourci la longueur du tube (9) du trépied avec précision au micron prés. It is understood that by turning the knurled sleeve (II) the length of the tube (9) of the tripod is lengthened or shortened to the nearest micron.

La FIG- 6 - représente le manchon,partie molletée (II) et les filetages (14) se vissant à l'intérieur des deux parties du tube (9). FIG- 6 - shows the sleeve, knurled part (II) and the threads (14) screwed inside the two parts of the tube (9).
