Description

Flushing cistern activation rod

The subject of the invention is the trigger rod of the flush toilet flush cistern, which makes it easy to adjust the stroke of the trigger rod.

The problem with wall mounted flush toilets is that the depth of installation can be different. The actuating rod is the connection between the flushing actuator mechanism and the actuating button on a wall-mounted bracket. At different installation depths, the actuating rod must be of different lengths, ie adjusted to the distance between the actuating mechanism and the actuating button.

The best known solution so far is from a competing manufacturer, which allows the length of the actuator to be adjusted to the depth of installation so that it is of a fixed length and adapted to the deepest possible flush mount. The active length of the rod is determined by the backing of the actuator to the actuator key holder. The connection ends with the screw connection between the nut and the actuating rod. The disadvantage of this solution is that it allows rotation even before the pole approaches the setting surface. Adjustment with depth or depth measurement is required. in some solutions, screw the screw to the reference surface.

The object and object of the invention is to construct the actuating rod and the associated assembly of the flush cistern in such a way that it will be possible to easily and always adjust its active length without measuring and further adjusting.

According to the invention, the problem is solved by the flush cistern activation rod according to an independent claim.

The invention will be described in the embodiment and in the drawings showing:

-2 The packer according to Figure 1 consists of a lever plate 10, a carrier 11 of the decorative plate and a decorative plate 12. The plate 10 is attached to the kettle under plaster and is mechanically and functionally connected to the mechanism for triggering the discharge of water. The carrier 11 is attached to the surface of the plaster. The distance between the plate 10 and the carrier 11 is usually between 20 and 80 mm, depending on the depth of installation of the kettle. This variation in the depth of installation must be adjusted by the actuating pole 1. The trim plate 12 is fixed via the bracket 11 and has at least one actuator key 13, 14. The head 3 of the pole 1 must be secured to the rear of the keys 20, 21. The nut 2 is pivotally mounted on the horizontal axis. to the crank lever 5, which is pivotally mounted to the back wall of the plate 10 on the horizontal axis. The rod 1 has three parts: the head 3, the part with guide ribs 4 and the stem 8 with thread and the guide shape 9. The length of the ribs 3 of the bar 1 is determined by the distance from the reference surface 7 to the keys 20, 21. The holes 15 on the plate 10, the shaped holes 16 on the carrier 11 and the threaded hole 17 of the nut 2 are in the same axis. The holes 15 are made of leaf-shaped safety springs 13. Along the edge of the shaped holes 16 on the carrier 11, safety nozzles 14 are made as triangular projections in the direction of the plate 12.

The rod 1 of FIGS. 2a and 2b has a head 3 that acts as a support for keys 20, 21. The portion of the rod 1 is the leading ribs 4. The rib profile 4 is aligned with the profile of the hole 16. The hole 16 restricts the movement of the rod 1 in the direction of the flusher when the rod 1 is in position for its insertion and positioning; the rod 1 hole 16 stops at the beginning of the ribs 4. When the pole 1 in its axis turns to the right angle, the ribs 4 and the hole 16 are caught so that the rod slides through the hole 16. The rib profile 4 is in the shape of a cross, with four rectangular blades made in such a way that the two lamellae are in the same plane and are perpendicular to each other. Two slats in the same plane with the plane of the leading shape 9 of the stem 8 of the rod 1 have a common length d2. The two blades perpendicular to the plane of the leading shape 9 of the stem 8 of the rod 1 have a common length d1. The stem 8 of the rod 1 has a thread 6 with an outer radius R. The shape hole 16 consists of a circular hole of diameter R1 and two additional vertical rectangular cutouts with an outer radius R3. The ratios are as follows: R1> R, R3> d2, d2> d1, d1 <R.

The thread 6 of the stem 8 of the rod 1 is of such a dimension that it cooperates with the thread 18 of the threaded hole 17 of the nut 2. The guide shape 9 of the stem 8 of the rod 1 is two parallel to the surface obtained by cutting the stem 8. The stem 8 therefore has a thread 6 on two opposite sides. and the leading 9 on the opposite two sides.

The plate 10 is fixed to the flushing cistern, the carrier 11 rests on the surface of the plaster wall and in a known manner connects to the plate 10. The rod 1 is inserted in the position of the vertical shapes 9 through holes 16 and 15 into the nut 2 to a depth when the ribs 4 are seated on surface 7 of hole 15. Thus determined

-3 the depth of the bar 1, which corresponds to the depth of installation of the kettle with respect to the keys 20, 21. After this phase of insertion of the bar 1, the bar 1 turns to the right angle; this locks the threaded rod 1 into the thread 18 of the nut 2. The ribs 4 are caught in a rectangular turn with the molded hole so that the rod 1 with its ribs 4 can move freely through the hole 16. When inserting the rod 1, the ribs 4 lean on the reference surface 7 and when the pole 1 is turned, the pole 1 with its ribs 4 rests on the retaining nozzles 14 and the springs 13 press the pole against the reference surface 7 so that the pole cannot be turned back uncontrollably. When the pole 1 is finally mounted, a plate 12 with the keys 20, 21 is fastened through the carrier 11. The construction of the invention ensures that the pole 1 is positioned so that its head 3 fits exactly to the back of the keys 20, 21.
