  • Patent number: 4797959
    Abstract: The invention relates to a sanitary unit having an automatic cleansing cycle. The unit comprises a lockable enclosure in which a partition defines a usage zone and a maintenance zone. A bowl is mounted for rotation between a utilization position in which it projects horizontally from the partition in said usage zone and a cleaning position in which it is tipped up into an opening in the partition so as to empty it into the maintenance zone. The upwards opening of the bowl is separated into two sections by a partition wall which extends upwardly to cooperate with the front walls of the bowl to form a rim surrounding the utilization section of the bowl. The bottom of the partition wall stops short of the base of the bowl to define an orifice and the rear section of the bowl forms an evacuation passage from the evacuation orifice rearwards to the maintenance zone when the bowl is tipped up.

  • Patent number: 4091477
    Abstract: A known type of base for a shower comprises a carrier having a shower tray. The carrier can be moved between a first position and a second position. In the first position the shower tray is substantially horizontal and can thus be used in taking a shower. In the second position the shower tray is substantially vertical and the carrier thus occupies less floor space. The improvement characteristic of the invention is the provision of a wash basin as part of the carrier; the basin opens upwards for use in washing when the carrier is in its second position.
