  • Patent number: 5405089
    Abstract: A shower head has a rigid body forming a pressurizable compartment having a downstream wall of composite synthetic-resin material having an inner face and formed with an array of throughgoing holes so that pressurized water in the compartment will exit therefrom through the holes. A unitary liner sheet of a soft elastomer has an outer face bonded to the inner face of the downstream wall and is formed with respective tubular nipples fitting in and projecting through the holes. Each nipple forms a throughgoing passage having an inner end opening in the compartment and an outer end opening outside the body. The liner sheet and integral nipples are molded in situ against the inner face of the plate forming the downstream wall of the shower body. The composite synthetic-resin material is a polybutyleneterephthalate and the elastomer is silicone or the composite synthetic-resin material can be polypropylene and the elastomer a thermoplastic.

  • Patent number: 5402977
    Abstract: An assembly for mounting a bath fixture to a wall having a surface formed with a plurality of holes opening at the surface has respective anchors seated in the holes, a bracket adapted to hold the fixture and having a face turned toward the wall at the holes, a disk of elastomeric material between the bracket face and the wall surface and formed with throughgoing apertures aligned with the wall holes, and respective screws extending through the bracket and through the disk apertures and securing the bracket to the wall with the disk compressed between the bracket and the wall. The elastomeric disk, which has a Shore A hardness of about 65 and a thickness of about 1 mm and may be made of closed-cell sponge rubber, prevents water from getting into the space behind the bracket, in particular into the region around the hole in the wall.

  • Patent number: 5377367
    Abstract: A hand-shower wall rod has vertically spaced and horizontally extending upper and lower brackets secured to a wall and a vertical tube with upper and lower ends respectively seated in the brackets. A soap-dish fixture has a body having a lower end formed as a soap dish and an upper end formed as an eye engaged around the lower bracket. The body is swivelable about a horizontal central axis of the lower bracket. A spring unit releasably holds the body in a normal position with the lower end below the lower bracket.

  • Patent number: 5368065
    Abstract: A shield is used in combination with a wall having an outer surface and formed with a throughgoing hole having an edge and with a plumbing fixture almost entirely recessed behind the wall surface and having a control part projecting forward through the hole past the surface. The shield is elastically deformable waterproof and is formed unitarily with a cup-shaped body generally surrounding the plumbing fixture and with an annular bellows-type cuff surrounding the control part and having a rear edge unitarily joined to the body and a front edge fixed to the wall surface at the hole edge. The plumbing fixture also has a laterally projecting connection nipple behind the wall adapted to be mated with a pipe behind the wall and the body is formed with a laterally throughgoing orifice fitted tightly around the nipple. Furthermore the shield is unitarily formed with an annular flange projecting laterally from the front edge of the cuff and fixed to the wall surface at the hole edge.

  • Patent number: 5356078
    Abstract: An adjustable shower assembly has a housing provided with a water-supply tube defining a seat, a core element fixed in the seat and having a stem extending from the seat along an axis and having an outer end formed with a noncircular boss generally centered on the axis, and a diverter formed with a central bore fitted over the stem and provided with at least two throughgoing passages. The diverter is at least limitedly rotatable on the stem. An end plate is formed with at least two sets of nozzles associated with the respective passages in respective angular positions of the diverter on the core element and formations on the end plate and diverter axially and rotationally fix the end plate on the diverter. A washer having a central hole complementary to and interfitting with the boss of the stem bears axially backward on the diverter and a screw threaded axially into the stem and bearing axially backward on the washer retains the diverter and end plate axially on the core element.

  • Patent number: 5348042
    Abstract: A flow-control valve has a housing having a chamber into which opens a port, a ceramic valve plate fixed in the chamber over the port, formed with a throughgoing aperture aligned with the port, and having a substantially planar face, and a ceramic control plate having a substantially planar face lying flatly on the valve-plate face and formed with a throughgoing aperture. The control plate can be pivoted relative to the valve plate about an axis substantially perpendicular to and traversing the surfaces between an open position with the control-plate aperture overlapping the valve-plate aperture and a closed position with the control-plate aperture aligned axially with a portion of the valve-plate face and offset angularly from the valve-plate aperture and with the valve-plate aperture aligned axially with a portion of the control-plate face and offset angularly from the control-plate aperture.

  • Patent number: 5340064
    Abstract: A bracket for supporting a hand shower adjacent a wall has a base part adapted to be fixed to the wall, formed with a throughgoing passage extending along a horizontal axis generally parallel to the wall, and having axially oppositely directed sides. A holder part pivotal on the base part about the axis on one of the axial sides of the base part is formed on the axis with an upwardly open seat adapted to receive the hand shower. A bolt extending axially through the passage has to the other axial side of the base part a threaded end and to the one axial side of the base part a radially projecting flange bearing axially toward the base part on the holder part. Interengaging formations on the bolt and base part rotationally fix the bolt in the base part while permitting it to move axially therein. A nut threaded on the threaded end of the bolt and bears axially on the other axial side of the base part.

  • Patent number: 5329967
    Abstract: A single-control mixing valve has an upwardly directed stem extending along a stem axis and movable relative to a normally stationary valve axis for regulation of flow through the valve. A lever assembly has a flange element having a socket fitted complimentarily over the stem and a plate having a periphery and extending transversely of the valve axis, a first screw secures the flange element to the stem with the socket fitted over same, and a lever having a cup-shaped base part formed with a downwardly open seat complimentarily fittable with the plate and an arm projecting laterally from the base part. The seat has a laterally open recess, and a second screw secures the plate in the seat with a portion of the seat periphery projecting laterally into the recess.

  • Patent number: 5318263
    Abstract: A rod assembly for mounting a hand shower on a wall has an elongated rod formed at each end with a transversely throughgoing and laterally closed hole and respective holder bodies each formed with a seat in which the respective end of the rod is complementarily engageable. Each body is formed with a passage alignable with the hole of the respective rod end when same is fitted thereto. Respective screws engageable through the aligned holes and passages of the rod and bodies with the wall secure the rod to the bodies and the bodies to the wall.

  • Patent number: 5297735
    Abstract: A hand shower has a shower housing having an inner end formed centered on an axis with an axially open central recess and an outer end carrying a shower head. A male coupling part adapted to be fixed to the end of a supply hose has a tubular outlet end engageable axially in the housing inner end. A latch element can be displaced radially of the axis in the inner end between a holding position engaging and axially retaining the coupling part in the recess and a freeing position allowing the coupling part to move axially freely into and out of the recess. The housing has a central feed tube forming the inner and outer ends and at least one rigid outer housing part surrounding and completely enclosing the central feed tube. Furthermore the shower includes a pair of such latch elements radially oppositely displaceable between the positions. These elements can be fitted without soldering or fusing into the housing for a very inexpensive and simple assembly of the device.
