Definitions

  • This invention refers to a bath tub made of composite material with an improved supporting frame.
  • the frame is made of metal tubes welded together and is secured to the tub by means of fibreglass-reinforced plastic during the step of reinforcing the tub with said material.
  • a further problem regarding the manufacture, handling and storage of the frames is that they are generally basket-shaped and practically complementary to the tub and, therefore, somewhat unwieldy.
  • the frame structure is made of several curved cut and welded metal tubes which must be subjected to anticorrosion treatment, such as galvanization, which is particularly lengthy and costly, due both to the size of the frame and, because of the use to be made of the frame, to the need to provide it with a very efficient corrosion-proof coating, which is very difficult especially on the welded areas due also to tortuous shape of the frame.
  • a further problem encountered with the aforesaid known technique arises whenever the tubs are to be made with one or more sides surrounded with removable panels, as is customary for example in swirl baths in order to offer access to the devices of the swirl-bath system for installation and maintenance.
  • the general scope of this invention is to obviate the aforementioned problems by providing a method for manufacturing a bath tub of the type made of composite materials, and a bath tub made according to said method which has a sectional supporting frame which is quick and easy to assemble.
  • a method for manufacturing a bath tub made of composite material of the type comprising a supporting metal frame disposed on the underside of the tub, characterized by the fact of comprising the steps of moulding the tub, applying a first substantially annular frame member around its edge, applying a second substantially flat frame member to the underside of the bottom of the tub, and interconnecting said first and second with third frame members.
  • Said method also advantageously comprises the further step of applying lateral wall elements around said tub by removably coupling said wall elements to at least said third frame members.
  • the method is advantageously also characterized by the fact that the first and second frame members are applied to the tub by partially incorporating them in fibreglass-reinforced plastic during the step of reinforcing the moulded tub with said fibreglass-reinforced plastic.
  • a bath tub made of composite material of the type comprising a supporting metal frame disposed underneath the tub, characterized by the fact of comprising, in combination, a first substantially annular frame member (12) disposed and connected around its outer edge, a second substantially flat frame member (15) disposed and connected to the underside of the tub, and third frame members (14) interconnecting said first (12) and second (15) members.
  • the embodiment according to the invention and generically indicated by reference 10 comprises a tub 11, moulded from composite material, inside the outer edge of which is secured a first frame member 12 made of bent metal tube.
  • Both the frame member 12 and the frame member 15 are advantageously incorporated into the structure of the tub during the reinforcing of the latter by means of fibreglass-reinforced plastic immediately after moulding.
  • the cross members 16 are advantageously generically shaped in the form of an upturned "G” while the longitudinal members 17 are generically shaped in the form of an upturned “U” and the portions of the members 16 and 17 in contact with the bottom of the tub are perforated so as to offer a better grip during their incorporation into the fibreglass-reinforced plastic.
  • the frame member 12 comprises four pins 13 which fit into a pair of shaped tubes 14.
  • the ends of the tubes 14 are clamped onto the pins 13. Moreover, as shown in figure 1 and in detail in figure 2, the tubes 14 are secured to the frame member 15, in correspondence with edges 18 of the cross members 16, by means of hooked fasteners 19 with a lock nut 20.
  • the tubes 14 are also fastened to one another by means of rivets or screws 21 and are provided with feet 22 by which the tub rests on the floor.
  • the tubes 14 can easily be fitted with elements for supporting the components of a swirl-bath system whenever the tub is designed to include a system of this kind.
  • figure 1 shows a pump support 32 advantageously secured by means of the screws of the feet 22.
  • the tubes 14 are shaped so as to define portions 23 and 24 substantially parallel to the lateral edges of the tub in correspondence with the four corners so as to enable the side panels 34 (for the sake of clarity only one of which is shown in the figure) to be fitted onto the tub by snapping into spring couplings 33.
  • Figure 4 and 5 show the fastening of a panel to the tub in greater detail. Unlike the previous drawings the tub is shown in the upright position.
  • the panel 34 has an indented upper edge to enable it to fit between the internal surface of the edge of the tub and a plurality of wire or flat springs 25 which can also be advantageously secured with fibreglass-reinforced plastic either to the surface of the edge of the tub or to the frame member 12.
  • each plate fixed onto each plate (for example by welding) is a traversable element 27 through which is inserted an L-shaped flexible element 28 which is locked in place by tightening a screw 29 exerting pressure against its surface.
  • a coupling unit 30 Fitted onto the free arm of the L-shaped element 28 is a coupling unit 30 which is frictionally locked in place by tightening a screw 31.
  • the unit 30 is provided from below with a complementary housing for part of a segment 23 or 24 of the tubes 14 so as to achieve the couplings 33.
  • the tub is reinforced with fibreglass-reinforced plastic in the usual way.
  • the frame members 12 and 15 are secured to the tub and then the moulded tub is subjected to the typical operations of trimming, finishing, drilling, etc.
  • the two frame members 12 and 15 do not prevent the tubs from being easily handled or piled one on top of the other since they are substantially adherent to the surface of the tub.
  • the side panels 34 are prepared and fitted with the plates 26.
  • overturned tubs can then go on to the normal assembly bays where the two tubes 14, joined together with rivets or screws 21, are applied by fitting their ends over the pins 13 and clamping them to lock them in place, and securing the intermediate portions to the frame member 15 by means of the hooks 19.
  • the supporting elements such as for example the pump support 32, are then secured to the frame. At the same time the feet 22 are fitted in place.
  • the tub can be placed upright to complete the assembling of the swirl-bath system, if included, and for the final tests and inspections.
  • the tub can also easily be used as a built-in bath simply by not fitting the tubes 14 and, if necessary, securing the feet 22 to the frame member 15.
  • the shape of the tub can differ from the one shown and the conformation of the frame can consequently also be different.
  • the method of securing the tubes 14 to the frame member 15 can be achieved for example by means of screws, clamps or coupling pins, as can be easily imagined by any technician.
  • the various frame members can be individually subjected beforehand to anticorrosion treatment, thereby reducing their cost considerably.
