Definitions

  • the invention relates to a holding device for seats on a carrier according to the preamble of claim 1.
  • seat shells are attached in rows next to each other on a support tube.
  • holding devices are provided in which the holder is designed as a bracket which engages around the support tube from below and the ends of which are bent outwards at right angles to form the support for the counter-holder.
  • the seat counter holder rests on the support of the bracket and is screwed to it.
  • a game occurs between these parts.
  • the seat can twist slightly under the movements occurring during its use with respect to the support tube, so that the seat does not have a perfect hold and so-called wobble movements occur. Often, due to their play instinct, users try to increase this wobble or twisting game.
  • the holder is formed by two halves of the clamp, which surround the tubular support and are fastened to one another with screws.
  • the clamp half overlapping the carrier from above has a downwardly projecting locking pin which engages in a form-fitting manner in a bore in the carrier.
  • a flange plate is attached as a support, which is screwed to a flange plate designed as a counter-holder below the seat surface of the seat. Because of the locking pin and the hole, it can only be mounted in a predetermined position on the carrier.
  • two holding parts are provided which surround a supporting tube and which are connected to one another by means of screws which pass through the supporting tube.
  • the holding parts are formed in one piece with edge profile parts, each of which has receiving grooves for the seat surface and the backrest of the seat.
  • the invention has for its object to design the generic holding device so that the seat can be reliably mounted on the carrier despite tolerances.
  • both clamping jaws are each provided with a support for the seat counter holder.
  • the counterholder rests with the leg on the support.
  • the two clamping jaws can be steplessly brought into the required position along the support and braced against it.
  • a positive connection between the jaws and the carrier is not provided.
  • the clamping jaws can be easily adjusted along the carrier in the position required for mounting the seat.
  • the seat can still be moved relative to the clamping jaws or its support by means of the counter-holder, so that the optimal installation position of the seat can be easily adjusted.
  • the seat With the clamping jaws, the seat can be clamped or attached to the carrier without play, so that any tolerances in the manufacture of the carrier and / or the holder can be compensated for perfectly.
  • the seat can be attached to the carrier in such a way that wobbling movements of the seat are reliably prevented.
  • the 1 and 2 show a bowl-shaped seat 1, as used for example in parks, in pedestrian zones and the like. It is attached to a carrier 2.
  • the carrier is preferably provided with oval tubes in cross-section, the ends of which are anchored in walls or which can be fastened on legs.
  • a holding device 3, 4 and 5, 6 is provided for fastening the seat 1 to the support tube 2. It consists of a first holder 3 and a first counter-holder 4 and a second holder 5 and a second counter-holder 6, each of which forms a pair of holders 3, 4 and 5, 6, respectively.
  • the counterholders 4 and 6 are L-shaped angle pieces which are attached to the seat 1 with their one leg 7 and 8 (FIG. 2). Your other legs 9 and 10 are spaced below the seat 11 of the seat 1 and point towards each other. The legs 9 and 10 have openings 12 and 13, 14 through which screws 15 to 18 are inserted for fastening the seat to the support tube 2.
  • the holders 3 and 5 each consist of two clamping jaws 3a and 3b or 5a and 5b (see FIGS. 3 and 4), which are mirror-symmetrical and are arranged relative to one another.
  • the jaws are preferably made of cast material and are braced against each other on the support tube 2.
  • the clamping jaws 3a and 5a have through openings 20, 22; 24, 26 and the jaws 3b and 5b threaded holes 19, 21; 23, 25 for screws 27 to 30 on. They are inserted through the through openings 20, 22, 24, 26 and screwed into the threaded bores 19, 21, 23, 25, whereby the clamping jaws 3a, 3b, 5a, 5b are pulled firmly against the support tube 2 and clamped thereon.
  • the through openings 20, 22, 24, 26 of the clamping jaws 3a, 5a open on the outside facing away from the opposing clamping jaw 3b, 5b in each case in an enlarged diameter 31 to 34, in which the screw heads 35 to 38 are countersunk.
  • the through openings and the threaded bores 19 to 26 are provided in thickened end sections 39 to 42, 39a to 42a of the clamping jaws 3a, 3b and 5a, 5b. They have rounded end faces 43 to 46, 43a to 46a and flat inner surfaces 55 to 58, 55a to 58a which face one another and into which the threaded bores and through openings 19 to 26 open. Between their thickened end sections 39 to 42, 39a to 42a or their inner surfaces 55, 55a; 56, 56a; 57, 57a; 58, 58a, the clamping jaws 3a, 3b and 5a, 5b each have a clamping receptacle 51 to 54 for the support tube 2.
  • the bottom of the receptacles 51 to 54 is at least approximately adapted to the shape of the supporting tube 2, so that the pairs of clamping jaws 3 and 5 (FIG. 1) can be reliably clamped to the supporting tube.
  • the clamping jaws 3a, 3b and 5a, 5b with their thickened end sections 39 to 42, 39a to 42a and the receptacles 51 to 54 provided in between have the clamping jaws essentially C-shaped.
  • supports 47 to 50 for the counterholders 4 and 6 of the seat 1 extend perpendicular to them.
  • the supports 47 to 50 which are perpendicular to the jaws 3a, 3b; 5a, 5b extend, are plate-like and each have an elongated hole 63 to 66 extending in the longitudinal direction of the supports and the support tube 2, through which, with the interposition of washers 71 to 74, screws 15 to 18 (FIG. 2) for fastening the seat 1 on the support tube 2.
  • the counter supports 4, 6 are placed on the supports 47, 48 and 49, 50 with their legs 9, 10, which run approximately parallel to the seat surface 11, for fastening the seat.
  • the clamping jaws 3a, 3b, 5a, 5b are arranged on the support tube 2 (FIGS. 1 and 2) in such a way that the supports 47 to 50 are directed in opposite directions to one another.
  • the nuts 67 to 70 are largely covered to the outside by the legs 7, 8.
  • the counterholders 4, 6 with their webs 9, 10 lie flat on the tab-like, projecting supports 47 to 50.
  • About the screws 15 to 18 and nuts 67 to 70 can between the jaws 3a, 3b; 5a, 5b and the counterholders 4, 6 a perfect adhesion can be achieved, whereby the seat on the oval support tube can be properly secured. Even when the support tube 2 is bent, a secure hold of the seat 1 is ensured via the elongated holes 63 to 66 in the supports 47 to 50.
  • clamping jaws which are advantageously made of a cast aluminum alloy, even larger tolerances as well as surface coatings can be compensated for perfectly, that they are held in the assembled position without play on the support tube 2 by their bracing.
  • the holders 3, 5, in particular their clamping jaws 3a, 3b and 5a, 5b, are first attached to the support tube 2.
  • the pairs of jaws 3a, 3b and 5a, 5b are attached to the support tube 2 such that it lies in the receptacles 51 to 54 of the jaws.
  • the jaws are connected to each other using screws 27 to 30.
  • the clamping jaws are braced against one another against the support tube 2, so that they have a perfect, play-free fit on the support tube.
  • the screws 27 to 30 are only tightened in the manner described so far that the clamping jaws for mounting the seat 1 can still be moved on the support tube 2.
  • the seat 1 with the counter-holders 4 and 6 attached to its underside is placed on the holders 3, 5 in such a way that the legs 9 and 10 of the counter-holders 4, 6 lie flat on the supports 47 to 50 of the holders 3, 5.
  • the seat 1 can then be secured against tipping on the clamping jaws 3a, 3b, 5a, 5b. Finally, the screws 27 to 30 are tightened so that the jaws and thus the seat 1 are clamped on the support tube 2 without tilting. Since the clamping jaws 3a and 3b or 5a, 5b are at a distance from one another, they can be clamped perfectly on the support tube 2.
