Definitions

  • the invention relates to a safety device for a drainage channel according to the preamble of claim 1.
  • a drainage channel is known, in which a traverse is cast into the channel body crossing the channel.
  • the cross member has a central threaded hole so that a cover placed on the channel body can be fastened by means of a screw bolt.
  • a safety device for a drainage channel according to the preamble of claim 1 is known from EP 82 111 076 A1. This is shown in FIGS. 11 and 12.
  • a channel body 1 is provided, the side walls 2 of which are connected via a base 5 and are provided with reinforcing ribs 4.
  • support surfaces 6, 6' are provided, on which a cover 30 can be placed.
  • a hole is provided in the cover 30, into which a fastening screw 16 can be inserted, the lower end of which is seated in a thread 15 of a swivel crossmember 80 '.
  • recesses 7, 7' are provided which are partially opposite one another, that is to say offset from one another, as shown in FIG. 11.
  • the recesses 7, 7 ' have a front wall 8, 8' and a rear wall 9, 9 '.
  • the cover 30 has been placed on the supports 6, 6 'with the screws 16 and the swiveling traverses 80' attached thereto and the screws 16 are rotated clockwise, the ends of the swiveling traverse 80 'swivel into the recesses 7, 7'. until the front edges of the swivel crosshead ends strike the front walls 8, 8 '.
  • the screw 16 is turned further, it is screwed further into the thread 15 in the swivel crossmember 80 ', so that the swivel crossmember 80' comes into contact with its ends on the upper walls of the recesses 7, 7 'and the cover 30 is firmly seated on the supports 6, 6 'of the gutter 1 is pulled.
  • the invention has for its object to further develop a securing device of the type mentioned in such a way that a freely configurable, but nevertheless durable securing of the cover on the channel body can be ensured.
  • traverse can be used subsequently, for example via a pivoting movement, so that one does not have to change the shape of the channel body with its recesses, but on the other hand this insertion process takes place with the cover removed. This makes it possible to insert the traverse properly, that is, completely into the recesses, the clamping devices ensuring a permanent hold in this position.
  • the clamping devices are preferably essentially symmetrical at both ends of the crossmember. This improves the traverse's hold in the gutter. It is possible to use manually operated spring bolts or the like as clamping devices. However, the clamping devices are preferably designed to be elastically deformable in such a way that they are deformed by the insertion movement of the cross member when they are inserted into the recess in the channel. This eliminates the need to operate the clamping devices separately.
  • the clamping devices are preferably captively attached to the crossbar. This simplifies the insertion work.
  • the insertion process is particularly simple when the clamping devices can be inserted in a plane parallel to the surface of the cover by a pivoting movement.
  • the securing device is particularly economical and simple to manufacture if the crossmember and the clamping devices are formed as sheet metal parts.
  • the clamping device (or two clamping devices) is preferably formed in one piece with the crossmember.
  • Such a one-piece design as a molded sheet metal part is preferably achieved by giving the cross member an essentially U-shaped cross section with a base and two legs. The clamping devices are then formed by band-shaped sheet metal sections which are bent out of the legs and separated from the base area.
  • the clamping devices comprise claws, which are used when the traverse is inserted be in firm engagement with the channel body. A loosening is only possible with great effort (and tools).
  • the clamping devices are designed at their ends so that removal is still possible. In this case, the force (torque) for removal is preferably greater than the force required for insertion.
  • the securing device described is used as part of a retrofit kit for replacing a swivel traverse according to EP 0081 741 A1, the fastening devices instead of the screwing device provided in the known object comprising a screwless locking device, as in the known object due to the missing rotational movement when it is inserted cannot be used.
  • the screwless detent preferably includes a clamp spring attached to the crossbar and a pin attached to the cover with a thickened leading end upon insertion, which are configured such that the pin is substantially perpendicular to the plane in which the cover extends Direction in a receiving opening of the clamping spring under its elastic deformation can be used and is held after insertion. The user is therefore only required to press the recess onto the channel body.
  • the thickened section is preferably conical at the front end and frustoconical at its end facing the cover. As a result, the push-in force is less than the force required to lift the cover off.
  • the receiving opening is preferably elongated in such a way that the pin can be inserted at any point along the longitudinal axis of the receiving opening. This means that even with larger tolerances there can be no difficulties when inserting.
  • the clamping spring is furthermore preferably attached with play such that the pin can move it into the receiving opening of the clamping spring when it is inserted. This ensures a further equalization of the game.
  • the receiving opening is also elongated, so that the pin can be inserted anywhere along the longitudinal axis of the receiving opening.
  • the clamping spring is further secured with play in a direction perpendicular to the longitudinal axis of the receiving opening such that the pin can move the clamping spring in the direction perpendicular to the longitudinal axis when inserted into the receiving opening.
  • the clamping spring is essentially band-shaped. It has a lower, essentially U-shaped or V-shaped spring section and two adjoining U-shaped holding sections, each of which merges with one leg end into a leg of the resilient section and whose open sides protrude outwards.
  • the clamping spring is inserted into a (rectangular) opening of the cross member such that it overlaps two opposite edges of the opening in the cross member with the legs of the holding sections.
  • the clamping spring can thus be moved within the opening, so that the edges of the opening are pushed more or less far into the U-shaped sections of the clamping spring.
  • the pin is screwed firmly onto the cover (e.g. instead of the known screw 16).
  • An arrangement which is characterized in that the pin is rotatably attached to the cover about its longitudinal axis, the increased thesecurity against inadvertent lifting off of the cover, the thickened end of the pin having two mutually opposite spreading surfaces, so that the pin at one Parallel position of the spreading surfaces to the longitudinal axis of the clamping spring receiving opening, the clamping spring opens and can be inserted into the receiving opening and removed from the receiving opening.
  • a drainage channel 1 is partially shown, the parallel side walls 2, 2 'are provided just under the upper edge 3, 3' or under supports 6, 6 'for a cover 30 with recesses 7, 7'.
  • These recesses 7, 7 ' correspond to the recesses which were explained at the beginning with reference to FIGS. 11 and 12.
  • a crossbar 80 with its ends 81, 81 ' is inserted into the recesses 7, 7'.
  • the crossmember 80 has a U-shaped cross section (see FIGS. 3 to 6), a base area 83, which runs essentially parallel to the cover 30, and two legs 84, 84 'being provided.
  • the legs 84, 84 ' are each separated from the base area 83 at one end 81 and 81' of the cross member 80 by a dividing line 85 and 85 '. This results in band-shaped sections which are each bent inwards in the direction of the other leg 84 or 84 '. This creates clamping devices 82 and 82 '. These can either be smooth at their ends (FIGS.
  • This swiveling-in process continues until the ends of the traverse 80, in particular the end sections of the base 83, strike the front walls 8, 8 'of the recesses 7, 7'.
  • the installation of such a traverse is just as easy as the construction.
  • the traverses thus formed can be equipped with threads 15, as are provided in the known arrangements (FIGS. 11 and 12), in order to fasten the cover 30 in the traverse 80 by means of a screw 16.
  • the crossmember according to the invention is the possibility of converting gutters manufactured in a known manner (according to FIGS. 11 and 12), possibly also gutters already installed, including their covers, in those in which the covers are held on the gutter with screwless detents .
  • the screwless locking comprises a fastening piece on the one hand 40, which can be fastened to the cover 30, on the other hand a fastening counterpart 20, which is fastened to the cross member 80 and can engage in a snap engagement with the fastening piece 40.
  • the fastening piece 40 comprises a pin (FIGS. 1 and 8) which has a front cone surface 42 (which leads to the latching movement) which merges into a tip 41 and an oppositely inclined holding surface 43 behind it, so that a thickened front end is formed is.
  • the holding surface 43 merges into a shaft 44, which in turn merges into a head 45.
  • the head 45 has a threaded bore so that it can be fastened to a cover 30 by means of a screw (as shown in FIG. 1).
  • the fastening piece 40 thus replaces the screw 16 previously provided.
  • the fastening counterpart 20 is designed as a spring and has a lower spring section 22 with a U-shaped or V-shaped cross section (see FIG. 7) and two upper U-shaped holding sections 23, 23 ′, each with a leg in the lower spring section 22 pass over and are arranged with their openings from one another to the outside.
  • a receiving opening 24 is thus formed between the holding sections 23, 23 '.
  • This receiving opening 24 is elongated when the fastening piece 20 is designed as a leaf spring (see FIG. 2), so that when the cover 30 is placed on the groove 1, the positioning of the fastening piece 40 or the tip 41 of the pin in the longitudinal direction of the groove relative to the receiving opening 24 is not critical. This enables tolerances to be compensated.
  • the crossmember 80 has an essentially rectangular opening 25 in the center (FIGS. 4 and 6).
  • a fastening counterpart 20 according to FIG. 7 can now be inserted into this opening 25 such that the legs of the holding sections 23 and 23 'overlap the edges of the opening 25 and come to rest on or below the base 83 of the crossmember 80.
  • the width of the opening 25 (in the longitudinal direction of the trough 1) is designed to correspond to the width of the holding sections 23, 23 ', so that the fastening piece 20 is fastened in the crossmember 80 essentially without play, as seen in the longitudinal direction of the trough.
  • the length of the opening 25 (seen transversely to the longitudinal axis of the channel) and the opening width of the holding sections 23, 23 'are dimensioned such that the fastening counterpart 20 can be displaced transversely to the longitudinal axis of the channel when the fastening piece 40 is inserted. This achieves a further tolerance compensation that is perpendicular to the longitudinal direction of the receiving opening 24.
  • the fastening counterpart 20 designed as a clamping spring can be made either of metal (FIG. 1, right) or of plastic (FIG. 1, left).
  • the material, but in particular the material pairings, are chosen so that corrosion can essentially be ruled out. This can also be achieved by passivating the surfaces.
  • the holding piece 47 shown there has a threaded hole, so that instead of the threaded hole provided in the head 45 there is a threaded pin on the fastening piece 40 (FIG. 8) which can be screwed into the holding piece 47.
  • the securing device shown here for a drainage channel can be used in a variety of ways in already existing systems and can be combined with already existing fastening devices, in particular for screwless locking.
