The insertion piece and the connecting piece form preferably a unit, which is locked into a bore of the hollow profile.

Abstract: The device has a mounting frame with a nut housing, into which a threaded rod is inserted. The threaded rod has interrupted teeth and meshes with a nut, which likewise has interrupted teeth. An adjustable carrier, with which the threaded rod can be detachably fixed at each depth of insertion, is arranged behind the nut. A time-consuming screwing in and out of the threaded rod as well as fixing with a lock nut are avoided.

Abstract: A flushing device has a first pushbutton for triggering a flushing with essentially the total amount of water present in the flushing tank and a second pushbutton for triggering a flushing with part of this amount of water. Both pushbuttons are connected to a valve pipe, which is to be raised during flushing and is mounted in a float housing. A beaker-shaped hollow body, which is raised as an additional weight with the closing element in the case of a partial flushing, is arranged in the flushing tank. The hollow body is raised with the closing element during a complete flushing and during a partial flushing alike. In the case of a complete flushing, the hollow body is opened by an opening such that water contained in the said hollow body flows out at least partially when the closing element with the hollow body is raised.

Abstract: A water collection trough has an edge arranged in the plane of a roof and a bottom, arranged with spacing from the edge, with an opening. The opening leads to a drainage pipe mounted down at the bottom of the trough. Two parallel plates are arranged spaced apart, a lower plate being fixed in the water collection trough and an upper plate being fixed above the edge of the water collection trough. The edge of the upper plate projects beyond the edge of the water collection trough in such a way that, to form a closed flow in the drainage pipe. The water to be led away is accelerated ahead of the edge of the water collection trough and, after a two-fold deflection of about 90.degree. in each case, ahead of the opening in the bottom.

Abstract: An electronic control device for the contactless control of a unit, e.g., a plumbing unit, especially a urinal, with at least one transmitter for sending directed light signals, and with a receiving device. The receiving device receives signals reflected from a scanned object and sends them to a circuit acting on the unit. The transmitter and the receiving device form an optical triangulation arrangement, wherein reflections are received from the background and from a predetermined detection zone to mask the said background.

Abstract: The flushing means has a flushing tank, which is connected to a flushing channel of a toilet bowl via a flushing elbow and to a nozzle (jet) via a connection pipe. During flushing, part of the flushing water is released from the top into the toilet bowl via the flushing elbow and the flushing channel, and another part is released into the lower area of the toilet via the connection pipe and the nozzle. The flushing water entering the nozzle is taken up by an opening of the connection pipe, which extends into the flushing elbow and is always open. To prevent the connection pipe from being suctioned empty and consequently to prevent the suctioning of a suction siphon from being interrupted, the connection pipe has a hydraulic seal, which hydraulically seals this pipe against a vacuum at the outlet opening of the connection pipe during a suction process. Valves and the like, which are susceptible to the deposition of lime, are not employed.

Abstract: The flushing device has an actuating device for optionally triggering a complete or partial flushing. A valve body of drain fittings is raised for this purpose. In the case of a partial flushing, the valve body is raised with a weight body, which loads the valve body with the valve body raised and brings same prematurely into the closed position against the lifting force of a float after a flushing process has been triggered. A coupling device has a switching member mounted on the weight body in its lower area. This switching member automatically connects the weight body to the valve body during the raising of the weight body with a pulling element connected to the weight body.

Abstract: To guarantee a higher reliability of operation, the capacity of a battery to reliably open and close a water valve and to operate a microprocessor is continuously checked. To do so, a plurality of reference voltages are formed. The current voltage of the battery is compared with these reference voltages, and the state of the battery is indicated on the basis of this comparison with, e.g., an LED.

Abstract: In a housing to be fastened to the bottom of a flushing tank, a float, which is arranged approximately centrally on a closing member mounted displaceably in the housing, is arranged under a partition extending horizontally in the flush tank. A sealing body is arranged at a lower end of the closing member. The partition forms a unit with a chamber arranged on its underside, and the unit is detachably inserted from the top into the housing, which is open at the top. The present invention simplifies the automatic mounting as well as the inspection of the drain valve and the more universal and therefore less expensive use of the valve housing.

Abstract: The frame has at least two hollow bars extending at right angles to one another and at least one connector, which connects the two hollow bars to one another at a distance from one another. The connector has a locking body as well as an expanding means in which the locking body engages an undercut groove of one bar with a head part and a front-side hollow space of the other hollow bar with a foot end. The locking body has a clamp-shaped design. The expanding means has an eccentric bolt, which expands the two legs at right angles to their longitudinal direction between the two hollow bars, thereby detachably connecting a head end and a foot end of the locking body to the associated hollow bar by clamping.
