Description

Stick tripod The main patent .155 196 relates to a stick tripod, at the tripod legs with a semicircular cross-section in the cavity as I t; 'l t ivf, J initv-, r,% 7, -eiidbaren StocZ it are arranged to be extendable. According to the additional patent 466) 552 are the extensions that can be pulled out of the semicircular tripod legs provided with eccentrically arranged stiffening ribs such that the two Ribs lie next to each other after folding the tripod leg extensions come. The invention relates to a further training of such tripod legs, to make them particularly stable. For this purpose, according to the invention semicircular outer tubes that form part of the tripod legs that can be extended from your stick form, provided with stiffening strips on their inwardly curved edges. These Stiffening strips are on the two semicircular outer tubes that belong together so offset to one another that they interlock when the tubes are folded together, d. H. in pairs next to each other - ;: come lying down.

An exemplary embodiment of the invention is shown in the drawing. Fig. I shows the upper part of a stick stand according to patent 455 196; the two The tripod handle can be pulled out of the hollow of the stick; c ind. in partially swiveled out Location shown. Fig. 2 shows a cross section along the line C-D of Fig. I on a double scale.

As in the additional patent .lt>(> 552, the embodiment uses two tripod legs that are articulated to the tripod head i Furthermore, an extension part 4. is articulated, which together finitely forms the third tripod leg as in the main patent: 155 196. The extension part .1 consists of a semicircular tube, in the cavity of which the two tripod legs 2, .2 'according to your Fold into place.

To ensure the stability of the stand, especially the outer tubes 2, z ', parts 2, 2 ', 3. 3' designed in cross section according to Fig. 2. The edges (", 6 'are with stiffening strips; ,; ' provided, which are arranged offset to one another are that they interlock when folded (Fig. 2), d. H. in pairs lying next to each other; n.

Both the tubes 2, 2 'and the profile rods that can be pulled out from them 3, 3 'can all be provided with low longitudinal ribs 8 be. All Tripod parts must be worked very precisely to prevent the tripod from wobbling. So far, a considerable amount of force has been required to pull the parts apart. In the new embodiment, this force is on the one hand when pulling out the pipes 2, 2 'from the cavity of the stick 5 and on the other hand when pulling out the profile rods 3, 3 'from the tubes 2, 2' are significantly reduced, because 8 are due to the elevations the surfaces rubbing against each other are reduced in size, but without fitting into one another of the parts to be picked up.

The previously known longitudinal ribs on stand tubes (Austrian patent 45 527) were used to locate pull-out parts that are mutually around their common Were to be twisted in the longitudinal axis.

Claims (3)

PATENT CLAIMS. ' i. Stick tripod, -consisting of a hollow, as Tripod foot with usable stick, in its cavity extendable tripod legs with semicircular cross-section can be accommodated according to patent 455 196 and in the the tripod legs have profiled parts, characterized in that the semicircular Outer tubes (2, 2 ') at their inwardly curved edges (6, 6') at an angle to these running stiffening strips Fig.?) are provided. 2. Stick tripod according to claim i, characterized in that these stiffening strips (7, 7 ') are offset in this way are arranged to each other that they intermesh when the tubes (a, 2 ') are folded together or in pairs next to each other. 3. Stick stand according to claim i or a, characterized characterized -that the outer surfaces of the pull-out parts (2, 2 ', 3, 3') are outside are provided with one or more longitudinal ribs (8).
