Definitions
- the invention relates to a water outlet mouthpiece for sanitary fittings, with a thread arranged on the inlet side for screwing with an external thread for direct or indirect connection to a sanitary fitting.
- These water outlet pieces are usually sleeve-shaped components for receiving inserts, for example aerators, sieves, water-saving inserts, sealing rings, etc.
- the sleeve-shaped components also have a thread, by means of which the water outlet mouthpiece with the inserts mentioned with the sanitary fitting, e.g. is screwed to a tap.
- the water outlet mouthpiece is either manually or with the help of a tool e.g. a fork wrench, which can be attached to appropriately designed parts of the mouthpiece, screwed onto the tap.
- mouthpieces In order to counteract this theft and vandalism, mouthpieces have been developed which have designs on their end faces for receiving a specially designed tool. However, these mouthpieces are "thick” and “chunky”, so unsightly. As is well known, great importance is attached to the aesthetic appearance of water fittings. For this reason, these mouthpieces have not been accepted by the consumer.
- the aim of the invention is to create a water outlet mouthpiece by means of which the disadvantages mentioned are eliminated and which is theft-proof while maintaining an aesthetic appearance.
- the water outlet mouthpiece according to the invention is characterized by a sleeve-shaped inner piece containing the thread for receiving at least one specific insert to influence a continuous water flow, and by a flat-walled, radially elastically deformable driving sleeve surrounding the inner piece made of a material and with a wall thickness that is radial Compression by an immediately applied human force make it impossible, which flat-walled driving sleeve is freely rotatably arranged on the inner piece and locked against axial displacement, which driving sleeve can be brought into a frictional engagement with the inner piece in a radially elastically compressed state, so that when rotating the Driving sleeve the inner piece is carried by the same, in order to loosen the water outlet mouthpiece from a respective counter thread, or screw the water outlet mouthpiece onto e to be permitted in the respective counter thread exclusively by
- Fig. 1 shows a longitudinal section through a water outlet mouthpiece
- Fig. 2 shows a section through an annular
- FIG. 3 is a top view of the tool according to FIG. 2.
- the water outlet mouthpiece shown in section in FIG. 1 generally has a sleeve-shaped inner piece 1 made of an expedient, conventional material, for example brass.
- the inner piece 1 has, in a known manner, an internal thread 2 arranged on the inlet side, for connection, for example, to a sanitary fitting, for example to the free end of the water outlet pipe of a tap.
- a perolator of known design is used, which generally has a lateral slots 3 provided bushing 4, in which an outflow-side screen unit 5 and an upstream-side screen unit 6 are used.
- a sealing ring 7 is connected to the perolator, by means of which the water outlet mouthpiece screwed to a respective water outlet pipe is sealed against water leakage.
- the inner piece 1 is freely rotatable in a driver bush 8, and secured therein against axial displacement.
- a locking member is formed.
- this locking member is a projection extending in the circumferential direction of the inner piece 1.
- This protrusion has a run-out slope 9 that extends somewhat bulged outwards and ends at a blocking surface 10 that extends in the radial direction of the inner piece 1.
- a recess 11 is also formed.
- the driver bush 8 has an inwardly projecting locking member which contains a flat, ramp slope 12 and a locking surface 13. There is a recess 9 next to it.
- the driver sleeve 8 and the inner piece 1 can be made of a material that is customary for water outlet mouthpieces, for example brass, whereby the visible outer surfaces of the driver sleeve 8 can be chrome-plated.
- the driver bush 8 is inserted, the two bevels 9; 12 a small elastic dodging takes place at the relevant points, after which a snap takes place. Because of the locking surfaces 10; 13, the two components 1; 8 (without damage or destruction) no longer pull apart, so that the driver bushing 8 can rotate freely, but in axial direction. ler direction is mounted immovably on the inner piece.
- the driving sleeve 8 consists of an elastically deformable material.
- the material and the wall thickness of the driving sleeve 8 are now selected such that the driving sleeve 8 cannot be compressed by hand or by a fist, that is to say generally by applying a human force.
- different materials can be selected for the production of the driving bush, on which the individual dimensions of the bushing depend on the fulfillment of the condition mentioned.
- a driving sleeve 8 made of brass and with an outside diameter of 23.5 mm should be mentioned.
- the area of the thread 2 would be 0.25 mm and the area of the water-emitting end of the recess 19 (greatest wall thickness) would be 1.7 mm.
- the distance between the driving bushing 8 and the inner piece 1 would be 0.01 mm in the area of the thread 2 and 0.04 mm next to the upstream end of the recess 11.
- the driving sleeve 8 is smooth-walled on its outside, so it does not offer a contact surface for a tool.
- the driver sleeve 8 In order to be able to screw the inner piece away (and obviously also screw it onto a respective pipe piece), the driver sleeve 8 must be elastically pressed together using a tool specially designed for this purpose in order to achieve a frictional engagement, that is to say a frictional engagement between the driver sleeve 8 and the inner piece 1 to create.
- the tool shown in FIGS. 2 and 3 serves this purpose.
- This tool is ring shaped and has an outer Tragerringkorper 14 for example made of a metal.
- An inner ring body 15 is inserted in the support ring body 14.
- This inner body 15, which can be inserted loosely, consists of an elastic material, for example rubber.
- the Tragerringkorper 14 is separated at one point by a slot 16.
- This slot 16 is bridged by a screw bolt 17 inserted in the support ring body 14.
- the support ring body 14 has at one end an inwardly facing shoulder 18 on which the inner body 15 rests.
- the tool is pushed onto the driving bush 8 until the shoulder 18 abuts the front end of the driving bush 8. Then the elastomeric inner body 15 is in the correct position relative to the driving bushing 8. It should be noted that the elastomeric inner body 15 has a considerable length. If the tool has been put on, the
- Screw bolt 17 tightened, in the example shown by means of an Allen key, and thus the elastomeric interior body 15 lies tightly against the driving bushing 8.
- the driving bush 8 is now tightly wrapped around the driving bush 8 by the continued tightening of the screw bolt 17, so that the latter is compressed elastically in order to lie firmly against the inner piece 1 on the inside.
- the contacting surfaces of the inner piece 1 and the driving bushing 8 do not necessarily have to be smooth-walled. They could be slightly roughened to increase the prevailing frictional forces.
- the inner piece 1 is carried by the driving sleeve 8 when the tool rotates, and can be screwed onto a thread or unscrewed from a thread without further notice.
- the tool is clamped using an Allen key.
- a screwdriver should be used for other designs of the head of the screw bolt. Instead of the threaded bolt, a buckle-shaped tensioning device would also be conceivable.
