  • Patent number: 8104111
    Abstract: A shower device is proposed that features a fixed-installation housing. This housing can, for example, stand up from the floor and may extend beyond normal human body size. The housing is fitted with a shower arm that can be moved out of an inactive position. In the inactive position, the surface of the shower arm lies flush with the surface of the housing. The jet discharge area of a shower head arranged in the shower arm faces inwards, so that it is only possible to see a flat surface on the exterior of the housing. Through pressure on this surface, a catch mechanism is released and this causes the shower arm to move out of the housing. This is accomplished via a drive mechanism, which may feature a spring, for example. Extension is performed at a relatively slow speed, which can be achieved using a damper device. The shower arm moves to a position in which the now-visible jet discharge disc of the shower head can be used as an overhead shower.

  • Patent number: 7343930
    Abstract: A fluid delivery system including a faucet and a hand-held sprayer is disclosed. The temperature of the water provided by the faucet is controlled independent of the temperature of the water provided by the hand-held sprayer. The temperature of the water provided by the hand-held sprayer may be controlled by a valve supported by the hand-held sprayer. The temperature of the water provided by the hand-held sprayer may be controlled through a control member supported by the hand-held sprayer.

  • Patent number: 7077150
    Abstract: A valve assembly includes an escutcheon that is secured to a valve housing by a threaded adapter. Thus, no screws need extend through the escutcheon, resulting in a more visually pleasing outer appearance. Further, a trim sleeve may be inserted into the escutcheon adapter to turn the escutcheon adapter relative to the valve housing and adjust the position of the escutcheon tightly against the wall. The present invention thus provides an escutcheon which need not have any screws to secure it to the fixed structure, but which is securely held to the valve housing.

  • Patent number: 7040542
    Abstract: A temperature measuring device and a flowrate measuring device are both connected to a regulating unit, thus enabling the mixing temperature of the mixing water flowing through a supply line and the flowrate to be determined. The regulating unit serves for controlling a mixing valve and a shut-off valve. At the end of the filling operation, the overall volume introduced into a container and input via a control apparatus has the likewise input desired temperature, the regulating unit continuously determines, based on the flowrate and the measured mixing temperature, since a starting time point, the actual heat quantity contained in a part volume which has already flowed out.

  • Patent number: 6892952
    Abstract: A water control module is provided that monitors water temperature in plumbing, such as shower plumbing, and receives certain input commands from a user. The water control module may, in one example, control shower water flow temperature to preferential temperature values. Control of shower water flow temperature is accomplished by receiving user input of desired water temperature on a user interface, sensing current water temperature in the plumbing, and processing the user inputs and sensed water temperature values to control water delivery temperature. In another example, the water control module may provide a display screen with numerical and/or graphical features to inform the user of desired and/or measured temperature values.

  • Patent number: 6874527
    Abstract: A flanged bushing top portion is applied to a sink or counter surface over a mounting hole with a skirt portion descending from the top portion of the flanged bushing in to the mounting hole. A tapered expansion sleeve is threaded into the skirt portion of the flanged bushing. As the tapered expansion sleeve is threaded upwards into the tapered skirt portion, the skirt expands and pressed against the inside diameter of the sink mounting hole thereby securing the flanged bushing to the sink surface. A faucet valve assembly, soap/lotion dispenser, or water dispenser is lowered into the bores of the flanged bushing and the expansion sleeve, and the valve's escutcheon collar is secured to the top of the flanged bushing by means of a lock down collar which is threaded onto the exterior threads of the flange of the flanged bushing. This secures the valve assembly, soap/lotion dispenser, or water dispenser to the flanged bushing and consequently to the sink.

  • Patent number: 6845526
    Abstract: A faucet has a spout and a pullout spray head connected to a flexible water supply tube and releasably connectable to the spout. The spout has a docking collar mounted thereon for receiving a connecting shaft of the spray head. The docking collar has an annular wall with a plurality of U-shaped slots which define a plurality of cantilevered snap fingers. Each snap finger includes a projection that fits into a groove in the connecting shaft when the spray head is docked. An elastomeric O-ring surrounds the annular wall at a point where the O-ring engages the snap fingers to bias them toward the groove. Ridges on the exterior surface of the wall retain the O-ring in place. The spout and docked spray head have parallel shoulders that define a mating plane. The projections and groove define a retaining plane. The mating plane is not parallel to the retaining plane such that rotation of the spray head about an axis normal to the mating plane will cause the projections to release from the groove.

  • Publication number: 20040199995
    Abstract: A device enables a user to selectively change the flow of water produced by a waterspout between aerated flow and non-aerated flow. The device is preferably implemented as an adapter that is threaded to or otherwise coupled to the end of a waterspout such as a kitchen or bathroom faucet waterspout or a bathtub waterspout. The device includes a closure mechanism that is operable by a user to permit or prevent aeration of water flowing through the adapter. The adapter may include a control ring that may be rotated by a user to selectively open and close bores for introducing air into the interior of the adapter. When the control ring is turned to an open position, air is introduced and an aerated water flow is produced. When the ring is turned to a closed position, air is not introduced and non-aerated or laminar flow is produced. A user is thereby enabled to select the desired type of flow.
