  • the base end of the tensioning device tightly encloses the upper end of the outer tube in the form of a sleeve. Straps extend from the base part, in which the fixing clamp is guided, which clamps the inner tube at a point corresponding to the desired extension length.

  • the tensioning lever is closed, the pressure roller slides over the overhang lug, causing the inner tube to be pushed out of the outer tube by a measure, so that the plates are pressed more firmly and the vertical support between the floor and ceiling is consequently braced.
  • the clamping device occupies an area on the outside of the vertical support, which is therefore not available for attaching brackets. Furthermore, the conspicuous tensioning device is aesthetically disruptive in certain applications.
  • a vertical support for the purpose relevant here is known, which likewise consists of an outer tube and a telescopically extendable inner tube, as well as attachment plates attached to the outer tube ends (see FIG. 1B).

  • the outer tube has an external thread section with an enlarged diameter, the upper edge of which has a conical inward bevel into which the clamping ring can be inserted.
  • the inner tube on which the union nut sits protrudes through the clear width of the clamping ring.
  • the clamping ring When screwed together, the clamping ring is opened by the tightened union nut the seat is pressed into the outer tube and narrowed due to the conical contours so that it closes more tightly around the inner tube and holds it in the extended position.
  • the base plate is screwed into the lower end of the outer tube with a threaded pin, so that the outer tube can be unscrewed over a clamping area at a distance from the base plate.
  • the ceiling plate is spring loaded in the upper end of the outer tube, so that when the outer tube is unscrewed beyond the preset length of the vertical support, tension is created between the floor and the ceiling.
  • the vertical support described above does not require any complex, externally disruptive tensioning device, but the fixing of the selected extension length of the inner tube by means of the clamping ring and the union nut is not secure to the required degree. If the vertical support, i.e. the inner tube is heavily loaded, it can slip through the clamping ring, even if the union nut is tight. In addition, the comparatively large union nut on the vertical support could negatively influence the overall aesthetic impression for special requirements, since the union nut does not harmonize with the brackets to be attached to the vertical support. In addition, clamping the vertical support between the floor and ceiling by rotating the outer tube at a distance from the floor plate is relatively tedious.

  • Eccentric mechanism is arranged. When twisting the pipes against each other, the eccentric mechanism causes the pulled-out tube to jam in the selected setting.
  • This vertical support has a relatively simple structure, but the load capacity is not great and the locking in the selected setting is not particularly secure. In addition, bracing against the ceiling is cumbersome and locking and releasing the eccentric mechanism can require considerable effort.

  • Clamping device in particular for stretching carpets. Two tubes pushed into each other are locked in the set length by means of a mechanical coupling. The device is not braced against a ceiling. The device is therefore unsuitable for use here as a vertical support.
  • clamp-type clamps and pipe clamps have been developed for attachment to support rods in general or vertical supports of the type here, which function with spring force or a tensioning screw.
  • the tube holder of the clamp holder is designed to be complementary or prismatic to the tube to be encompassed.
  • An embodiment of the latter type is shown in the aforementioned brochure "THE AUTOPOLE COLLECTION”.
  • the clamp holder which is similar for scaffolding, is fastened to the support rod by means of clamping screws, and supporting elements, such as brackets or hooks, can be fixed to the clamp holder with another clamping screw. Due to its chunky shape, this clip holder is hardly considered, for example for the presentation of outerwear. It also prepares additional manufacturing and Assembly effort to attach the intended support elements by means of a clamp connection.

  • you have to cover a relatively long screw path with the connecting screw which is a problem.
  • the half-segments of the clamp holder must first be opened wide when they are attached to the vertical support and then braced in order to sit firmly on the vertical support.
  • the invention is based on the problem of creating a telescopically extendable vertical support with an inner and outer tube, the selected span - e.g. between floor and ceiling - can be locked securely with a few simple steps and without complex screwing, even when the vertical support is subjected to greater loads. It should also be possible to clamp the extended vertical support between the lower and the upper limit in a simple manner.
  • An additional premise for the invention is that a pipe can be continuously extended over a wide range and can be locked and tensioned in any extended length.
  • the mechanism for locking the extended length and for tensioning must not impair the external appearance of the vertical support; it is therefore desirable to arrange the mechanics at least for the most part inside the vertical support. Furthermore, the entire pipe length - apart from the areas near the floor and ceiling plates - should be available for the optional attachment of brackets.

  • the important thing here is to increase the screwing process previously required for attaching and removing the clamp holder from a support rod or the vertical support according to the invention. loan to shorten and thus enable its faster assembly and disassembly. Furthermore, it should be avoided that one has a separate screwing tool to carry out the remaining screwing process.

  • the clamp holder must be able to be steplessly moved on a support rod or the vertical support, be securely fixed in the selected position even with higher loads and harmonize aesthetically with support rods or vertical supports.
  • the vertical support according to the invention is characterized in that a mechanical coupling based on contraction and expansion is provided between the mutually displaceable inner and outer tubes, which coupling can be actuated by a transmission means, in particular a linkage, that leads axially out of the tubes.
  • This linkage is preferably guided to the bottom side of the vertical support and moved axially or rotating.
  • the coupling has two cones that are shifted against each other and surrounded by a bundle of coupling elements. When the coupling is relaxed, the cones are further apart, so that the bundle has more space available for its radial contraction.

Abstract

Le montant vertical de soutien conçu pour la présentation de marchandises, pour l'installation de supports d'information ou d'éléments de décoration, est constitué d'un tube interne (2) et d'un tube externe (3) à déplacement télescopique sur le tube interne. Une fois déterminé le point d'appui, un dispositif d'accouplement permet de bloquer les tubes, interne et externe (2, 3), l'un contre l'autre. Le dispositif d'accouplement mécanique se fait par contraction ou extension des deux tubes (2, 3) et est actionné à l'aide d'une tige émergeant axialement des tubes. Dans ce cas particulier, il a été créé pour ledit montant vertical de soutien un support de serrage (100) facile à ouvrir et à serrer. La clé à douille concue pour actionner la vis de serrage peut être maintenue dans le support de serrage (100).
