Definitions

  • the invention can be applied to most existing lavatories without the need to modify them in any way, since the spraying device and its supporting member in particular serve to restrain the bottle containing the liquid, while the actuating lever can adapt to widely differing lavatory pan shapes, including pans with acutely curved surfaces.
  • This invention relates to a spraying device comprising a bottle which contains a liquid under pressure possessing deodorizing, scenting or disinfecting properties, said bottle being equipped with a valve capable of spraying the liquid into the surrounding air when a person using the lavatory on which said spraying device is mounted pivots the lavatory seat and thereby actuates said valve.
  • the amplitude of the seat movement required to both trigger and arrest the spraying is large, it may be a nuisance for the user or may not be covered in full when the latter moves the seat; on the other hand, if the necessary amplitude of this motion is small, that is to say if the seat retains an approximately horizontal position ⁇ while describing the motion required to trigger and arrest the spraying, then such prior art actuating means become complicated and unreliable.
  • the subject spraying device of this invention is actuated by the pivoting motion of the lavatory seat, such motion being of small amplitude whereby the seat invariably remains in a substantially horizontal position during actuation of the spraying device, the latter being characterized by the fact that the spraying valve on the bottle containing the liquid under pressure to be sprayed is a proportioning valve and by the fact that this proportioning valve together with the drive transmitting means interconnecting it with the seat are so devised that spraying takes place when the user rises from the lavatory seat and the latter pivots upwards responsively to elastic restoring means.
  • the spraying device comprises, by way of a support, a bracketshaped member one of Whose walls rests on top of the edge of the pan, while its other wall rests against the lateral surface of the edge of the pan.
  • This bracket includes a horizontal surface for supporting the bottle, the drive transmitting means between the seat and the proportioning valve consisting of an actuating lever hingedly connected to said support and on which the lavatory seat bears, while the tip of this lever extending outwardly in relation to the pan is adapted to actuate the proportioning valve.
  • FIG. 1 shows in partial section with cutaway portions a lavatory equipped with a preferred embodiment of the subject spraying device of this invention, the seat being shown in a slightly raised position.
  • FIG. 2 shows the same lavatory in corresponding fashion to FIG. l, the seat being here shown in abutment against the edge of the pan.
  • FIGS. 3 and 4 depict, respectively in perspective and in section, a rst alternative embodiment of part of said spraying device.
  • FIGS. 5 and 6 are sectional portrayals of two different embodiments of an important component part of the subject spraying device of this invention.
  • FIG. 7 shows in partial section a lavatory equipped with yet another alternative embodiment of the spraying device according to this invention.
  • the lavatory proper which is not shown in its entirety, includes, as well known per se and as shown in FIGS. l, 2 and 7, a pan 1, a seat 6 hingedly connected thereto about Ia hinge line AA located behind pan l, a lid (not shown) being possibly pivotally connected about the same hinge line AA.
  • the pan 1 is formed with a rim 2 extending round its upper opening.
  • FIGS. 1, 2 and 7 depict this lavatory in partial section through a vertical plane parallel to hinge-line AA and located substantially halfway between the front and rear of pan 1.
  • the rim 2 of pan 1 includes a horizontal wall 3, an inside wall 4 and an outside wall 5, the seat 6 being capable of abutting against horizontal wall 3 of rim 2 through the agency of blocks 7 preferably made of rubber.
  • the spraying device includes a bottle 8 containing a liquid 9 under pressure.
  • This spraying device is operated Aby a pivotal motion of seat 6 of small amplitude, whereby seat 6 invariably remains in a position very close to the horizontal position While the spraying device is being actuated.
  • the spray-valve of the bottle 8 containing the pressurized liquid 9 to be sprayed is a proportioning valve which, together with the drive transmitting means interconnecting it with seat 6, is devised so that spraying takes place when the lavatory user rises from the seat 6 and the latter accordingly also rises responsively to elastic restoring means.
  • bottle 8 is fixed to the side of pan 1, approximately halfway between the front and rear thereof.
  • the position of bottle 8 in the vertical sense is prefer lably such that operating plunger 11 of proportioning valve 10 project slightly above the plane tangential to the horizontal wall 3 of rim 2, both in the final position (shown in FIG. 1) lbetween which said plunger 11 can be moved.
  • the drive transmitting means between seat 6 and plunger 11 of proportioning valve 10 may consist of an actuating lever 12 one of whose ends bears upon plunger l1 and whose other end is pivoted about a pin 13 fixedly carried in a suitable support on the horizontal wall 3 of rim 2 of pan 1, and this actuating lever 12 is Iarranged so that it extends between said horizontal wall 3 and the seat 6 when the latter occupies a horizontal position (resting on pan 1) or a substantially horizontal position (when it is raised slightly by the elastic restoring means).
  • the elastic restoring means may be a spring or else the pressure of the gas used to atomize the liquid to be sprayed, which spring or pressure is designed to act on plunger 11 and to be tr-ansmitted to seat 6 through drive transmitting means consisting of actuating lever 12.
  • the hinge pin 13 of lever 12 is fixed to the rim 2 of pan 1 through the medium of a preferably bracket-shaped supporting member 14 which bears against the horizontal and outside walls 3 and 5 of the rim 2 of pan 1, and the lavatory seat 6 bears on lever 12 in an area located between hinge pin 13 land plunger 11.
  • the hinge pin 13 for lever 12 is fixed to the rim 2 of pan 1 through the medium of a supporting member 14, and the seat 6 bears on lever 12 in an area located on the side of hinge pin 13 remote from plunger 11.
  • a spring 90 urges lever 12 in the direction tending to raise seat 6 and exerts a force greater than that of the spring of proportioning valve 10 or of the pressure of the pressurizing gas.
  • Supporting member 14 is preferably made of plastic and is held in position by securing means to be described hereinbelow.
  • the horizontal wall 15 of supporting member 14 is formed with an indentation 16 in the bottom of which is positioned hinge pin 13, a more or less large portion of lever 12 lodging itself inside indentation 16 in the course of its pivotal motion (FIG. l2).
  • supporting member 14 is restrained upon the rim 2 of pan 1 -by an adhesive coating 17 whose two sides possess a powerful adhering capacity and which is interposed between horizont-al wall 3 of rim 2 and wall 15 of supporting member 14, and also by abutments 18 made of a non-slipping substance such as an elastomer foam.
  • Bottle 8 can be fixed with advantage to pian 1 by means of a horizontal wall 20 which is rigid with the vertical wall 19 of supporting member 14 and which projects from pan 1 and is formed with an indentation 21 into which the upper part of bottle 8 can be inserted.
  • the plunger 11 of bottle 8 may conveniently be formed with a spherical cap 25 comprising a collar 26, while the end of lever 12 yadjacent plunger 11 may be formed with a hole 27 through which cap 25 extends, with the lever 12 bearing against collar 26 which lodges in a recess 28 formed in said lever.
  • Bottle 8 is preferably made of a transparent material such as glass or an appropriate plas- 4 tic so that the level 29 of the pressurized liquid it contains may be visible.
  • the liquid is sprayed through a horizontal hole 30 drilled through plunger 11.
  • the proportioning valve 10 proper may be devised as shown in FIG. S and may be equipped with the spraying device shown in FIG. 7 (in which spraying occurs when plunger 11 of proportioning valve 10 is depressed).
  • Proportioning valve 10 comprises:
  • a plunger 11 urged upwardly by a spring 50 and carried in a hollow tube 51 formed with a port 52 which, when plunger 11 is in its uppermost position, is masked by a seal 53, the lower end of hollow tube 51 being equipped with ⁇ a ⁇ valve 54 which, when plunger 11 is in its bottom position, is adapted to mask an orifice 55 in a pipe 56 dipping into the liquid to be sprayed;
  • pipe 26 supplies the second chamber 60 through transfer passage 59, and in the lowermost position of plunger 11 valve 54 masks the orifice 55 in pipe 56 while port 52 places second chamber 60 in communication with the spray-hole 30 via transfer passage 59, thereby causing spraying to take place.
  • proportioning valve 10 may be devised as shown in FIG. 6 and may equip the spraying device shown in FIGS. l and 2 (in which spraying takes place when plunger 11 of proportioning valve 10 is in its uppermost position).
  • Proportioning valve 10 in this case comprises:
  • a plunger 11 urged upwardly by a spring 70 and carried by a hollow tube 71 formed with a spray-hole 30 which, when plunger 11 is in its uppermost position, is positioned above a seal 72 and which, when plunger 11 is in its lowermost position, is located below seal 72, the lower end of hollow tube 71 being obturated;
  • a second chamber 76 which may be formed with advantage inside plunger 11 in communication with hollow tube 71, the interior volume of hollow tube 71 and of second chamber 76 being at least approximately equal to the volume of liquid sprayed each time plunger 11 moves from its lowermost position to its uppermost position.
  • the seat 6 When the lavatory is not in use, the seat 6 is raised slightly by lever 12 in relation to its utilization position wherein the blocks 7 bear, responsively to the weight of the person seated on seat 6, against the rim 2 of pan 1.
  • the lever 12 itself then occupies its uppermost position corresponding to the initial position of plunger 11 (FIG. 1).
  • the lavatory When the lavatory is to be used, the user sits on seat 6 without bothering about the fact that the latter is slightly raised, as a result of which the seat is applied against the rim 2 of pan l through the medium of rubber blocks 7 (FIG. 2).
  • spring 50 urges plunger 11 back into its initial position (FIG. 1) and, by reason of the type of proportioning valve adopted, a deodorizing or scenting liquid is sprayed into the surrounding air through hole 30.
  • Actuating lever 12 may be made hollow whereby to embody a passageway for the liquid to be sprayed, in which case the spray would be directed into the pan 1.
  • the present invention provides for an alternative ernbodiment of the support for the spraying device.
  • lever 12 is obtained integrally with the support 14 proper by a single injection moulding operation.
  • Lever 12 is then connected to support 14 by a plastic hinge consisting of a thin zone a the constituent molecules of which are appropriately oriented and which interconnects the bevelled edges of support 14 and lever 12, whereby the latter is capable 0f pivoting in relation to support 14 about an aXis forming the hinge-line 13.
  • the lever 12 is operated several times in order to form the hinge, after which lever 12 is snapped into the indentation 16 on the support with the aid of moulded-on cleats 32, whereby the lever then adopts the position in relation to the support shown by dot-dash lines in FIG. 3.
  • lever 12 is devoid of an opening for passage therethrough of cap 25 but instead its end is hollow and covers cap 25.
  • a lavatory equipped with the subject spraying device of this invention offers many advantages, the main ones being the following:
  • the invention can be applied to most existing lavatories without the need to modify them in any way, since the spraying device and its supporting member in particular serve to restrain the bottle containing the liquid, while the actuating lever can adapt to Widely differing lavatory pan shapes, including pans with acutely curved surfaces.
  • a spraying device comprising a bottle containing a pressurized liquid to be sprayed; proportioning valve means for spraying upon actuation a predetermined amount of the liquid, said valve means being actuated by a small amplitude pivotal movement of said seat whereby the latter remains in a near horizontal position in the course of actuation of said valve means; and actuating means comprising elastic restoring means cooperating with said seat for permitting slight pivotal movement of the latter from a rest position when the user sits down on said seat and for moving said seat back to said rest position when the user rises from said seat, and drive transmitting means between the seat and said valve means and cooperating with the latter so that the spraying takes place during movement of said seat from said tilted back to said rest position.
  • a spraying device as defined in lclaim 2 wherein said seat bears upon a portion of said actuating lever between said hinge line and said valve means.
  • a spraying device as dened in claim 2, wherein said proportioning valve means comprises wall means forming in said bottle a rst chamber in communication with said pressurized liquid therein, a hollow plunger arranged for reciprocation relative to said first chamber between an upper and a lower end position in which the interior of said hollow plunger communicates with said irst chamber and elastic means forming a second chamber communicating with the interior of said plunger and that of said first chamber at least when said plunger is moved to said lower end position thereof, said plunger being moved from said upper lto said lower end position by said actuating lever and said elastic restoring means acting on said plunger for moving the latter back to said upper end positions.
