Definitions

  • Closure for an upwardly open drainage channel which has a frame, on the a cover for a firm and releasable connection with the frame rests, wherein the Lock a fastener and below the frame one with the frame firmly arranged pocket for receiving the fastener, wherein the Fastener a bolt or a socket pin for the fixed and detachable Connection is.
  • the teaching of this invention is based on the object, a closure of to develop DE 19545131 A1 known type, the without change to the Frame of the sewage gutter optionally different attachment possibilities for the Cover allowed, a quick release by locking means allows, and the one high security against unauthorized loosening of the connection guaranteed.
  • the cassette consists of a base body, a lid, and a threaded plate and a spreading spring arranged under the threaded plate, between the legs of which a wedge-shaped slide is inserted.
  • the cassette is inserted in a pocket below the frame of the drainage channel such that an opening arranged at intervals in the frame overlies one another with an insertion opening in the cover. Axial to this opening are also the threaded plate and the spreading spring.
  • the cover can now be fastened with a screw bolt by screwing it into the threaded plate or with a locking pin which is pressed into the spreading spring underneath. In the threaded plate there are two opposing recesses, so that the locking pin can pass through the threaded plate unhindered.
  • the inserted in the cover plate locking pin is secured against rotation and has for dipping into the cassette down towards a flattening of the shaft, the narrow sides are also conically shaped downwards.
  • the spreading spring With the conical surfaces on the shank of the locking bolt, the spreading spring is pushed apart in the cassette.
  • the conically shaped end of the shaft ends with a taper, which forms a two-sided paragraph on which hang up the two legs of the spreading spring and so fix the clamping bolt and hold.
  • the invention is therefore based on the object, a closure for a after Open at the top drainage channel, which has a frame on which a cover is up to developing, without altering the frame of the sewage guts optional different mounting options for the cover allowed and a small technological manufacturing and assembly costs required.
  • a threaded nut for alternative mounting with a bolt for a screw is fixed to the pocket of the frame or even solvable fixed in position.
  • FIG. 1 The wear of a frame 1 a sewage channel with a cover 2 is in Figures 1 and 2 clearly shown in section.
  • a threaded plate 4 fixed but detachable and a Form part 5 is arranged with a spreading spring 6, so that the frame 1 both a Screw connection and a snap connection allows.
  • Fig. 1 is a to Screw 7 inserted into the cover 2, in the threaded plate 4 in the usual way is screwed.
  • a locking pin 8 in the cover 2 is fixed and secure against rotation used in the assembly of the cover 2 on the gutter through the opening of the Threaded plate 4 is pressed into the spreading spring 6 and a Snap connection with the spreading spring 6 produces.
  • the threaded plate 4 has two on opposite recesses 4.1, so that the flattened locking pin. 8 unhindered through the threaded plate 4 can be inserted through.
  • the spreading spring 6 is displaceable in a molded part 5 with an angled wall 5.1 used. In case of wear or contamination can threaded plate 4th and / or molded part 5 are exchanged with spreading spring 6.
  • Fig. 3a to 3d the individual positions of the slidably inserted in the mold part 5 spreading spring 6 are more apparent.
  • the spreading spring 6 is located in a slot of an angled wall 5.1 of the molded part 5.
  • An unlocking of the snap connection between the expansion spring 6 and pin 8 can only be done with an externally accessible auxiliary tool, such as a screwdriver. This auxiliary tool is guided for this purpose between the wall 5.1 and the foot 6.2 of the spreading spring 6 and the spreading spring 6 is moved against the molded part 5.
  • a locking pin 8 is stirred and locked by the parallel legs 6.1 of the spreading spring 6.
  • the spreading spring 6 itself is locked by the s-shaped bends 6.3, whose inner surfaces 6.4 engage around the lugs 5.2 angled on the molded part 5. If the socket pin 8 is to be unlocked, then the spreading spring 6 is retracted by means of an auxiliary tool - as shown in Fig. 3b. The bevels 6.5 of the s-shaped bends 6.3 of the spreading spring 6 slide over the edges of the molded tabs 5.2 of the molded part 5 and the legs 6.1 are pressed apart and give the. Locking pin 8 free. The spring ends of the spreading spring 6 are also based on the tabs from 5.2. When removing the plug pin 8 from the pocket 3 - Fig.
  • Fig. 4 the spreading spring 6 is shown enlarged.
  • the profile edges on the further bevels 6.6 are for better effectiveness in engagement with the Locking pin 8 folded when removing it from the frame 1, which is e.g. by an embossing tool can be done.
  • the spreading spring 6 is in the unlocked position and is supported with its ends on the tab 5.2.
  • When pulling out the Bolt 8 from the frame pushes the edge 8.1 of the plug pin 8 against the oblique bkantung 6.6 of the spreading spring 6 and thus moves it in the direction of her Starting position.
