  • Patent number: 4523734
    Abstract: The holding device for a shower post is provided with a holding member, which can be fixed by a fixing element to a wall and which can be coupled to the shower post. At least the outer wall surface of the holding member is made from a transparent to clear material and is made matt to reflecting on the inside by an unglazed design. In conjunction with the transparent construction of the outer wall surface, this ensures that it is not possible to see into the interior of the holding member, the latter assuming the color of the wall to which the holding member is fixed.

  • Patent number: 4266730
    Abstract: A spray device having an attachment member for connecting the device to a stationary water supply and a spray head for discharging the water. The spray device includes at least two wedge-shaped connecting members, each having at least one wedge surface, the wedge-shaped connecting members being rotatably connected to one another along a plane, to the wedge surfaces of adjacent connecting members. One of the wedge-shaped members is rotatably connected to the attachment member. Another wedge-shaped member has the spray head mounted thereon. The attachment member and the wedge-shaped members provide communicating water passages between the stationary water supply and the spray head, whereby the spray head may be tiltably adjusted toward and away from the attachment.

  • Patent number: 4141502
    Abstract: A pulsating water jet massage shower head comprises a shower head housing which has an interior chamber which opens outwardly. A nozzle member comprising a flat plate nozzle portion in a cylindrical fitted portion is fitted into the chamber of the housing and it is provided with a plurality of nozzle bores which extend through hollow cylindrical pin portions which extend upwardly from the interior surface of the plate portion. A cover member is arranged in the housing chamber spaced inwardly from the nozzle member and it has a segmental closing disk portion which acts to deflect water which is delivered through connecting conduits in the housing so as to cause rotation of a valve rotor positioned between the cover member and the nozzle member. The deflection and the rotation of the valve rotor produce rotating water jets through the nozzle bores.
