Definitions

  • the invention relates to an assembly frame according to the preamble of claim 1.
  • the stator hollow profile has a longitudinal slot on one side wall or on two opposite side walls, the longitudinal edges of which are bent inwards and each have an inward toothing.
  • Each horizontal support has a vertical fastening flange which bears against the stator side wall and has at least one opening which is penetrated by a threaded bolt of the clamping device.
  • a holder On the inner end of the threaded bolt, which protrudes through the longitudinal slot of the stator into the hollow profile, a holder is fastened in a rotationally fixed manner, - which has a greater width in the transverse direction than the longitudinal slot and has molded locking profiles on its outward-facing side, which engage in the gaps in the teeth can.
  • On the threaded bolt there is a freely movable pressure piece in the form of a spring plate or spring bushing, the outward-facing side of which is subject to the action of a pressure spring which surrounds the threaded bolt and is arranged between a fastening nut screwed onto its outer end and the pressure piece.
  • the holder consists of a flat, rather thin metal plate, the four edges of which are bent outwards at a right angle; the longitudinal side edges, which must be oriented horizontally in the correct mounting position, form the locking profiles engaging in the tooth gaps, while the bent narrow side edges of the holder overlap the longitudinal edges of the stand on both sides. Since the holder has no middle part engaging in the longitudinal slot and its lateral overlap with the bent longitudinal edges of the stand is only slight, it is guided poorly on the stand. Correct adjustment or adjustment of a carrier with the clamping device, the holder of which is not clearly visible inside the stator hollow profile and is partially covered by the carrier itself, therefore requires laborious manipulation in order to bring the holder into its exact position.
  • the carrier can unintentionally detach itself from the tooth gaps by the latching profiles of the holder sliding out.
  • Another disadvantage is that essentially only the locking projections of the holder itself, that is to say the narrow edges of its bent longitudinal side edges, form the pressure surfaces which act directly on the toothed profiles; this can damage or deform the toothings, and the contact pressure initially exerted by tightening the fastening nut in the area of the toothings as a result of material fatigue can decrease.
  • the invention is based on the object of designing a mounting frame of the type described at the outset such that the clamping device can be adjusted effortlessly and without the risk of the carrier being released unintentionally when the carrier is being attached or adjusted, and that the toothing of the stand are relieved of the contact pressure of the holder.
  • the holder has two parallel grooves, in which the toothed longitudinal edges of the slot 3 are guided, and in that at least one catch is arranged in each of the grooves, which engages in the toothing 4 .
  • the two surface areas of the holder lying laterally outside of the grooves are expediently designed as flat pressure surfaces which transmit the contact pressure to the stator side wall while relieving pressure on the catches and the toothings.
  • the holder is designed as a block-shaped part, the two parallel grooves on its surface facing the carrier are provided, the distance and width are dimensioned so that the toothed longitudinal edges engage with play.
  • the central area of the block located between the grooves can protrude into the longitudinal slot.
  • the catches can be locking pins that pass through the grooves transversely.
  • the holder with its central part located between the grooves, engages relatively far into the longitudinal slot, which is delimited by the longitudinal longitudinal edges of the upright, which have the serrations.
  • the holder is guided in its correct orientation and secured against rotation, since it can practically never inadvertently slide inwards, even with a loose fastening nut, by adjusting the spring play accordingly, so that both locking pins Vietnamese disengage from the tooth gaps at the same time. Therefore, the clamping device. can be attached or adjusted practically effortlessly to the desired height with the carrier, and unintentional loosening of the carrier is practically impossible with all manipulations.
  • the teeth of the stand are designed in the manner of saw or wolf teeth, the long tooth flanks of which are inclined obliquely upwards from the tooth base and the short tooth flanks of which are essentially horizontal or slightly downward inclined and a concave curve at the transition to the tooth base for securely engaging the teeth
  • the known teeth which have rectangular, symmetrical teeth; forms the tooth profile shape in the mounting frame according to the invention, a safety toothing, which allows a problem-free, safe engagement, adjustment and fixing of the carrier at any height.
  • the carrier can be adjusted upwards by simple displacement, the fastening nut only having to be loosened to such an extent that the holder with the threaded bolt can slide inwards in the axial direction of the threaded bolt against the action of the compression spring when the locking pins slide on a long tooth flank, until the locking pins have passed the tooth tip in question, whereupon the holder automatically in the following tooth gaps snap into place.
  • a carrier To move a carrier downwards, it is suitably first be lifted slightly and at the same time as far down the threaded bolt against the action of the compression spring inside, that the R get astchane out of engagement with the sets of teeth, whereupon the carrier may be moved down to; when the threaded bolt is then released, the holder automatically engages again under the action of the compression spring and secures the carrier in the desired position.
  • the fastening nut can have an integrally formed ring flange on its inside with an annular groove receiving the outer end of the compression spring in the manner of a spring sleeve, whereby it is reliably avoided that the spring end is pressed into the screw thread.
  • the mounting frame according to the invention is preferably, as mentioned at the outset, equipped with so-called hanging supports as stands and is therefore intended for attachment to a ceiling or a ceiling structure for the laying of lines, pipes or the like, but it can also be easily anchored to the floor to have.
  • the mounting frame can be used as a shelf, the horizontal supports carrying the shelves or plates.
  • the stands can also each have a longitudinal slot on opposite sides with corresponding, inwardly oriented serrations, so that supports can be attached either on one or the other side or on both sides.
  • the mounting frame has a vertical stand 1 in the form of a hanging pole with an upper horizontal fastening flange 2 (FIG. 1), which is fastened to a ceiling structure.
  • the stator 1 so suspended from the ceiling without réelle Shen on the ground, consists (ig F. 2) of a substantially rectangular hollow profile with a provided on its one long side wall central longitudinal slot 3, the longitudinal edges at right angles to the inside bent and are provided with an inwardly directed 'teeth 4 (Fig. 1).
  • a horizontal support 5 can be detachably and vertically adjusted in height with a vertical fastening flange 6 having at least one opening 7.
  • a clamping device with a threaded bolt 8, a holder 9, which is rigidly attached to one end of the threaded bolt 8, a pressure piece 12, which sits loosely on the threaded bolt, one on the other End screwed fastening nut 13 and arranged one between the latter and the pressure piece 12, the threaded bolt 8 surrounding compression spring 14.
  • the Klemmvorrich- t u n g is so arranged that the threaded bolt 8 provided in the mounting flange 6 of the carrier 5 opening 7 and the stator longitudinal slot 3 interspersed and at its inner end the befind- l i chen within the stator hollow profile holder 9 supports, while the thrust member 12 and the Be fastening nut 13 sitting on the outer area of the threaded bolt. 8
  • the holder 9 is a block-shaped part (Fig. 3), the transverse dimension of which is greater than the width of the longitudinal slot 3, and has on its outward-facing surface two parallel grooves 10 which are oriented vertically in the correct mounting position and are thus arranged and dimensioned that the longitudinal edges with their sets of teeth 4 can engage with play in these grooves 10 (FIG. 2).
  • Each of the two grooves 10 is traversed in the transverse direction by two parallel locking pins 11, the spacing of which in the example considered is twice the distance between the teeth of the toothings 4, so that both locking pins 10 can engage in tooth gaps at the same time.
  • the holder 9 since the central region of the holder 9 between the grooves 10 engages relatively far from the inside into the longitudinal slot 3 delimited by the toothings 4, the holder 9 is guided well, and by appropriate adjustment of the play of the compression spring 14 can be practically prevented with certainty that the holder 9 is inadvertently moved inwards even when the connection is loose, that both locking pins 11 could slide out of the teeth 4 at the same time, causing the support 5 to slide off and the holder 9 to be rotated out of its correct fastening position.
  • the serrations 4 olfszähnenwashmaschineaji GmbHungen as in the form of sawdust or W is formed, the long-tooth flanks 4a obliquely upwardly directed are, while the short tooth flanks substantially horizontally or slightly downwards inclined run and at the Merge tooth base into concavely rounded tooth gaps 4b, into which the locking pins 11 can securely engage in their fastening position.
  • This tooth profile also allows a problem-free height adjustment of the carrier 5, in that it only needs to be moved upwards after the fastening nut 13 has been loosened slightly, the locking pins 11 compressing the compression spring 14 and correspondingly displacing the holder 9 inwards along the tooth flanks slide, as shown in Fig.
  • the pressure piece 12 In order to secure the position of the compression spring 14, the pressure piece 12, as shown in FIG. 1, is designed as a spring sleeve receiving the inner spring end, while an annular flange 13a is formed on the inside of the fastening nut 13, which annular groove receives the outer spring end , also in the manner of a spring sleeve, limited.
  • the invention is not limited to the exemplary embodiment described, but rather allows multiple variants with regard to the design of the individual components.
  • the stand 1 can also be a stand to be anchored to the floor.
  • the stand can be designed such that it has longitudinal slots with corresponding serrations on two opposite sides, so that supports 5 can be fastened on both sides of the stand.
