Definitions

  • the invention relates to a method and apparatus for the production of mouldings, more particularly parts of room modules with sanitary devices, of thermoplastics panelsby deep drawing in deep-drawing apparatus in which the thermoplastics panel is clamped along its edge, the moulding having integrally moulded parts, more particularly sanitary devices.
  • the invention also relates to a deep-drawn moulding, namely a room half for a room module with sanitary devices.
  • the invention relates principally to the construction and production of deep-drawn mouldings of large volume of the kind employed in sanitary engineering. More particularly, it relates to the production of parts such as halves for forming room modules with integrally moulded sanitary devices.
  • Complete bathrooms and shower rooms of plastics material are formed by a proven method from two room halves which are produced by deep-drawing.
  • the desired sanitary devices namely bath tubs, shower trays, wash basins, W.C. pans are integrally moulded when the aforementioned dishshaped room parts of large volume are deep-drawn.
  • the room halves formed in this manner are joined to each other along an approximately central vertical plane of the room module along a flanged edge of the moulding produced during the deep-drawing operation.
  • the flanged edge results from the perimetric clamping of the plastics panel.
  • the width or depth respectively of the sanitary devices which are integrally moulded during the deep-drawing operation is also subject to light limitations because the maximum dimension of the sanitary device in question cannot exceed the depth of the room half.
  • the invention proposes a method in which the plastics panel which is clamped in the deep-drawing mould and is in the mouldable state is initially preformed against the deep-drawing deformation in the zone of parts, more particularly sanitary devices, which project outwardly beyond the plane defined by the clamped edge of the plastics panel, and is then deep-drawn.Preforming of the projecting zones of the mouldings is preferably preformed by movable mould parts of the deep-drawing mould.
  • the plastics panel is formed in two directions in the deep-drawing mould after being plasticized namely initially out of the deepdrawing mould in the zone of the projecting parts and then in the usual manner by deep-drawing, namely inward drawing into the deep-drawing mould.
  • the moulding thus produced has zones which project beyond the plane defined by the clamped edge.
  • the deep-drawing mould according to the invention for performing this method is provided with mould parts which are movable and may be locked in the limiting positions in accordance with the number and shape of zones which are to be performed.
  • the invention may be employed with particular advantage for the production of bath tubs and shower trays which are to be integrally moulded into the room half. It is proposed that the jacketed side member of the bath tub or shower tray respectively, nearest to the adjacent room half, is moulded by deformation of the outer wall of the said side member beyond the zone of the median parting plane of the room module. A bath tub or shower tray respectively of the required dimension will then be produced on room modules which are relatively small or narrow respectively.
  • FIG. 1 is a vertical section through a room module with sanitary devices assembled from mouldings according to the invention
  • FIG. 2 is a horizontal section along the line IIII of FIG. 1,
  • FIG. 3 is another embodiment of a room module shown as a horizontal secton
  • FIG. 4 is a vertical section IVIV of FIG. 3,
  • FIG. 5 is a longitudinal section through a deepdrawing device according to the invention.
  • the invention relates principally to the production of room modules with integrally moulded sanitary devices.
  • Room units of this kind in which sanitary devices are provided at the works with the necessary fittings and connectionspare referred to as sanitary cells.
  • Such sanitary cells are delivered ready for use to the location at which they are to be employed and are merely connected at such location, namely in the building structure, to'the local services which are already available.
  • the room modules preferably comprise two room halves 10 and 11 each formed by deep-drawing of a thermoplastics panel 12 (FIG. 5).
  • the room halves l0 are joined to each other, for example by adhesive fixing, welding or the like. along a flanged edge 13 or 14 respectively.
  • the edge 13 of 14 respectively is formed by clamping the thermoplastics panel 12 into the deep drawing mould.
  • the room halves 10 and 11 are provided during production by deep-drawing with integrally moulded sanitary devices, for example with a bath tub 15, a wash basin 16, a W.C. pan l7, shower tray 18 and the like. Since such parts of the mouldings can be formed in only one of the room halves l0 and '11, the depth of such room halves 10 or 11 respectively is frequently insufficient to permit optimum dimensioning of the parts, more particularly of the bath tub 15 and of the shower tray 18.
  • the side member 19, associated with a bath tub l5 and being disposed nearest to the adjacent room half 10 is correspondingly shaped, more particularly the outermost wall 20.
  • the latter is provided with an indentation, namely outside the perimetric edge 14 or 13 respectively. This produces a recess on the bath tub 15 which is desirable for the freedom of movement within the sanitary cell because the bath tub or its outer wall respectively returns into the plane of the edge 14 in the floor zone.
  • the shower tray 18 in the embodiment illustrated in FIGS. 3 and 4 is similarly constructed. However, since it is difficult to install the service connections below the floor of the shower tray in the particular construction thereof the outer wall 21 of the side member 22, initially formed when the shower tray is moulded, is subsequently cut off as far as the upper edge of the side member in order to provide easier access from that side to the underside of the shower tray 18.
  • a vertical wall 23, formed in the zone of the adjacent room half 10, is disposed in the plane of the side member 22 and forms a buttjoint with the upper edge of side member 22.
  • the shower tray 18 is therefore accommodated in the sanitary cell with optimum dimensions and in a spacesaving manner.
  • the room halves l0 and 11, constructed in this way, are produced in a specially constructed deep-drawing mould, one embodiment of which is illustrated in FIG. 5.
  • the thermoplasies panel 12 initially plane, is clamped on the upper edge of a rigid mould box 24 along its edge 13 or 14 respectively. for example by means of a perimetrically extending clamping frame 25.
  • the mould box 24 contains mould parts which correspond to the shape of the moulding which is to be produced. Individual mould parts are movably supported.
  • a mould part 26, adapted to form the side member 19 of a bath tub. is movably disposed in the deep-drawing mould.
  • the mould part 26 may be moved beyond the plane defined by the clamped plastics panel 12 (dash-dot line) by actuating means.
  • the plasticized plastics panel 12 being correspondingly raised in this zone.
  • the plastics panel 12 is drawn completely into the deepedrawing mould, namely into the mould box 24 and thus surrounds at least partially the mould part 26 to produce the hollow, double-walled side member 19.
  • the mould part 26 is detachably supported on the piston rod 28 of the pressure medium cylinder 27.
  • the mould part 26 is initially removed from the deep-drawing mould with the moulding and is subsequently removed from the zone of the side member 19.
  • a moulding comprising a deep-drawn thermoplastics panel with integrally moulded sanitary devices such as a bath tub, shower tray, W.C. pan and the like for forming room modules or so-called sanitary cells by the assembly of two room halves along a longitudinal median plane defined by the outer edged of each half characterized in that at least one of the integrally moulded sanitary devices has an outer wall which projects outside the outer edge beyond the longitudinal median plane defined by the edges which are joined to each other.
