Definitions

  • the pivot axis of the locking member is designed as a lock part which can only be inserted into the bearing point in a specific pivoting position of the locking member. As soon as the locking member is pivoted out of this pivoting position, the pivoting axis and thus the locking member is blocked against being lifted out of the bearing point.
  • the disadvantage here is the special shape for the pivot axis and the fact that the closing member can only be lifted out in a certain pivot position.
  • the closing member is a backflow flap in a cleaning pipe in wastewater technology
  • this design of the pivot axis as a lock part leads to the fact that in the region of the bearing point, which is at least partially cylindrical for the pivoting mobility of the pivot axis, there are free spaces which grow with deposits which gradually allow the free pivoting of the backflow flap affect.
  • the backflow flap can only be lifted out in a special swivel position, usually in the full open position. This has to be done when the cleaning shaft and the subsequent pipes have to be cleaned, and because there may be other parts in the cleaning pipe, e.g.
  • each backflow flap can only be removed with complete removal of all insert parts, which is laborious and labor-intensive since these parts then have to be reinstalled cleanly.
  • the blocking is necessary because it must be ensured that no backflow flap is automatically lifted out of its swivel bearing.
  • the invention is based on the technical problem To create swivel bearing of the type mentioned, which allows the closing member to be used and lifted practically in any swivel position.
  • the object is achieved according to the invention by the features specified in the characterizing part of the main claim.
  • the locking part which only needs to prevent the pivot axis from sliding out of the bearing point, can be made so small that it can be easily removed without removing further components of the cleaning tube after removing the cover. Then the closing member can be pulled out straight up without colliding with other parts in the cleaning tube which may be closely adjacent. Then there is also undisturbed access to the areas behind the backflow flap for cleaning. Reinstalling the locking element is just as easy. Since the pivot axis no longer has to be designed as a lock part in this embodiment, its manufacture is simpler and, moreover, the advantage is achieved that it sits in the bearing position without clearance, so that no deposits can deposit. The functional reliability of the closing element is also improved.
  • FIG. 3 Another expedient embodiment of the invention, in which the closing member is fastened to a swivel lever, in whose head part is arranged the transverse pivot axis, and wherein the pivot bearing has a pocket for pivotally receiving the head part, can be seen from claim 3.
  • This embodiment is also characterized by a low overall height for accommodating the locking part, which, however, does not hinder the pivoting movement of the head part.
  • the locking part is practically fully integrated into the swivel bearing.
  • a further, advantageous embodiment variant of the invention in which coaxial pivot axis stubs are formed on both sides of the head part of the pivoting lever, each of which lies in a bearing point, is evident from claim 4. Since both stub axles are prevented from being lifted out by the locking part, the closing member cannot be inclined.
  • the cylindrical design of the stub axles also ensures reliable avoidance of deposits that are dangerous for deposits and provides easy pivoting mobility.
  • the locking part is easily detachably fixed in its blocking position by a latching or also by a locking screw. It also holds the locking member when the cover is removed from the cleaning shaft for some reason.
  • a further advantageous embodiment of the invention in a cleaning shaft of a cleaning tube containing at least one closing member and closable with a releasable lid explains claim 8.
  • the lid which is anyway required for closing the cleaning shaft, is entrusted with the additional task of either fixing the locking part in its blocking position or to form the locking part at all, with which the lifting of the pivot axis of the closing member is prevented.
  • the locking member is secured very securely as long as the cleaning tube is in operation and the cover is closed.
  • the closing member can be easily lifted out immediately after removing the cover closing the cleaning shaft and is automatically blocked against being lifted out again when the cover is put on.
  • the feature of claim 10 is also important, since it is precisely with modern plastic deformation techniques that the locking part can be shaped in such a way that it acts very precisely and therefore precisely, without the manufacturing costs for the lid being appreciably increased.
  • a cleaning tube 1 is shown in a longitudinal section, which consists of a discharge pipe section 2, an inlet pipe section 3 and a cleaning shaft 4 lying between them and open at the top.
  • the cleaning shaft 4 is delimited at the top by a peripheral edge 5, on which a cover 6 is placed at the top and fixed with fastening elements 7.
  • R1 and R2 In the cleaning shaft 4 there are two backflow closures R1 and R2, one behind the other, each of which consists of a backflow flap 9 which is fastened to a pivot lever 8 which is pivotable about a pivot axis 11.
  • Each backflow flap 9 is assigned a sealing seat 10, the left sealing seat in FIG. 1 being structurally integrated in the cleaning tube, while the right sealing seat 10 in FIG. 1 is arranged in an insert part 16 which can be inserted into the cleaning tube from above and fixed therein or can be secured in position by the cover 6.
  • Each swivel axis 11 consists of two stub axles 11a, 11b arranged coaxially on the swivel lever head part 8a, which are semi-cylindrical in shape in a bearing point 12.
  • the bearing point 12 is delimited by a raised wall 20.
  • an upwardly open pocket 13, 17 for the pivot lever head part 8a is formed, which is guided up to a front edge 19.
  • the pocket 13, 17 divides the bearing point 12 into two halves, to which the sliding slot 18 leads.
  • the bearing point 12 is again limited at the front by a raised wall 20.
  • In the sliding slot 18 of the bearing point 12 engage again from above two pins 22 forming a locking part, which are formed on the underside of the cover 6 and block the pivot axis 11 from being lifted upwards.
  • the insert part 16 has a raised edge 23, which is adjoined on both sides of the pocket 17 by a projection 25 which leads to the sliding slot 18.
  • the bearing point 12 is delimited by the raised wall 20.
  • the wall 20 is transferred directly over the edge 19 into the sealing seat 10.
  • the cover 6 drawn off in FIG. 2 has a transverse groove 29, which is adjoined by a shoulder 26, of which the two are spaced apart by the thickness of the pivoting lever head part 8a and hang the pins 22 forming the locking part.
  • the free ends of the pins 22 can be provided with concave surfaces which are curved in line with the curvature of the stub axles 11a, 11b.
  • the swivel lever head part 8a with the stub axles 11a, 11b forming the swivel axis 11 is hung in the direction of the dashed arrow 27 in the bearing points 12 before the cover 6 is placed from above in the direction of an arrow 28. Then the edge 23 dips into the groove 29 and the surface 26 lies e.g. on surface 25. As a result, the insert part 26 is first secured in position. At the same time, the pins 22 enter the sliding slots 18 until they finally secure the pivot axis 11 against lifting out.
  • FIG. 3 shows a further embodiment of a pivot bearing for an insert part 16 ′ which, similar to the insert part 16 from FIG. 1, can be accommodated in the cleaning shaft 4 of the cleaning tube 1.
  • the insert part 16 'with its sealing seat 10 has a pocket 32 at the top, which has a shoulder 41 near its upper end and ends in an edge 33 at the bottom. This can be seen particularly well from FIG. 4, where the pivot bearing is shown in the disassembled state and rotated by 90 ° with respect to FIG. 3.
  • Fig. 3 also shows a section in the plane III-III in Fig. 4.
  • the bearing point 12, to which the sliding slot 18 leads, is formed on both sides of the pocket 32, the sliding slot 18 being delimited on the outside by vertical walls 38.
  • Each bearing point 12 is delimited at the front by a raised wall 20 which prevents the stub axles 11a, 11b forming the pivot axis 11 from sliding out towards the front.
  • An inverted U-shaped locking part 34 is provided from above downward-pointing pins 36 inserted into the sliding slot 18 (in the direction of an arrow 39) such that it overlaps the pivot lever head part 8a previously used in the direction of an arrow 37 on both sides and does not hinder its pivoting mobility.
  • the pins 36 are fastened to a transverse yoke 35 which lies at a distance above the upper side of the swivel lever head part 8a.
  • the top of the locking part 34 is expediently aligned with the top of the insert part 16 '.
  • the cover 6 (not shown) can therefore come to rest directly there with a flat underside, as a result of which not only the insert part 16 'is secured in position, but also the locking part 34, which prevents the pivot axis 11 from being lifted out.
