BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a side view of a toilet bowl connected to a ventilating system according to the invention, Figure 2 i9 an enlarged view of the encircled portion 2 of figure 1, Figure 3 is a cross-sectional view along line 3-3 of figure 2, Figure 4 is a cross-sectional view along line 4-4 of figure 2, Figure 5 is a cross-sectional view taken along line 5-5 of figure 4, and Figure 6 is an exploded view of the parapet housing and its cover to be connected to a hinge member holding the seat cover of the toilet bowl.
DETAILED DESCRIPTION OF THE DRAWINGS
Figure 1 illustrates a toilet bowl 10 on which is mounted a seat 12 and a seat cover 14 hingedly connected at the rear by a hinge member 16 over the back apron 18 of the toilet bowl 10. The present common practice for securing the hinge member 16 according to the present art consists of bolting the latter to the apron 18 through a pair of apertures 20 which extends through the apron 18. Such apertures 20 are usually fairly large, having a diameter of about 3/8 to 5/8 of an inch which is filled by a large plastic bolt extending through them.
These apertures are used exclusively for locating the bolts which have substantially the same diameter as the apertures 20.
I
One of the essential features of the present invention is to use the apertures 20 as an intermediate portion of the ventilating channel which allows the ventilating piping to be hidden under the apron 18 instead of extending over it. Such astute direction of the air pathway improves the appearance of the ventilated bowl having a ventilating system which are provided with a piping arrangement completely above the apron.
Considering that the present invention can be installed on a conventional toilet bowl and seat cover, the new components can be provided as a kit to be substituted for the present means for anchoring the seat cover and the toilet seat on the back apron.
The assemb]y according to the invention comprises a parapet-like housing 22 having a peripheral wall which is sufficiently elongated to cover both apertures 20. The lower edge of the housing is flat and abuts over the upper surface of the apron 18 and is provided with a forward hooking member 24 to allow the seat 12 and the seat cover 14 to pivot thereabout along a common axle. The housing 22 is provided at both ends with a slot 26 for holding the head of the anchoring bolts 28. The bolts 28 are located to extend down the apertures 20 and through a pair of T-shaped couplings 30 having a vertical and a lateral channel.
The couplings 30 are open at the upper end of their vertical channel to allow the air to pass from the apertures 20 down through the couplings 30 and is closed at their lower ends with perforated plates 32 which allow the bolts 28 to extend thereth-rough. A wing nut 34 serves to tighted the housing 22 to each coupling 30 in solid abutment with the apron 18. The couplings have an opened lateral channel projection 36 extending rearwardly and adapted to be fitted to a piping arrangement 38.
The piping arrangement 38 preferably extends to an adjacent wall of the toilet room in order to reach a ventilating fan 40 hidden from view and possibly sufficiently remote to minimize the sound of the fan.
A cover 42 is adapted to be fitted over the parapet-like housing 22 to define the pathway of the air passage from the toilet bowl 10 to the piping arrangement 38. The cover 42 has two sidewalls 44 and a rear wall 46 fittingly surrounding the corresponding peripheral walls of the housing 22 and a front wall 48 forwardly and spacedly located relative to the corresponding forward peripheral wall of the housing 22. The front wall 48 has a lower edge 50 which is spaced above the upper surface of the apron 18 at a level which allows the air from cavity 51 of the bowl 10 to flow under the seat 12 and extend under the edge 50 and below the upper surface of the cover 42 and down inside the parapet-like housing 22 along the arrow A shown in figure 5. The bolt 28 which has a cross-sectional dimension substantially reduced from the cross-sectional dimension of the aperture 20, allows the air to flow through the arrows B and down into the coupling 30 along the arrow C and into the piping arrangement 38 along the arrow D (see figure 5).
The upper surface of the cover 42 is maintained in spaced relationship with the parapet-like housing 22 so as to allow flowing through the arrow A to meet no hinderence from the cover. The cover 42 is dimensioned to be fittingly surrounding the housing 22 so as to prevent unintentional removing of the cover 42.
The lower surface of the parapet-like housing 22 is preferably designed to be in abutting contact with the upper surface of the apron 18 so as to prevent any water unintention-ally overflowing from the toilet bowl 10 to flow into the housing 22 towards the couplings 30 and the piping arrangement 38. The sl.ots 26 are provided into an inward upper ledge 51 at both ends of the housing 22. Considering that the conventional apertures 20 in toilet bowls are substantially l.ocated at the same distance from one make of bowls to the other, any small adjustment can be taken up by the length of the slots 26.
As it can be particularly seen in figure 3, the location of the bolts 28 relative to the aperture 20, is intentionally located along the periphery of the apertures 20 to prevent the seat 12 and the seat cover 14 to be laterally pushed over the bowl 10. The position of the bolts 28 may be appropriately located inside the apertures 20 along different parts of their periphery according to the shape of the apertures 20 and preferably in their most remote position relative to each other.
Although the present invention has been described with a pair of couplings 30, only one coupling having an elongated shape substantially corresponding to the periphery of the housing 22 can also be contemplated.
As illustrated in figure 1, the fan 40 is located adjacent a rear wall of the toilet bowl 10 to project air through the rear wall 52 along the arrow E. The arrow F in stippled line (figure 1) indicates that the fan could be located, as an alternative, in a forward direction of the toilet bowl 20 up to a nearby wall which may be suitably located for the installation of the fan 40.
As particularly shown in figure 6, the hinge member 16 has two components, that is, a member 54 adapted to be connected to the seat cover 14 and a member 56 adapted to be connected the seat 12. Depending on the hinge member 16 of a particular toilet bowl, the hooking member 24 of the hinge member 16 is connected to be fitted by a pair of coaxial pins 58 so that the seat 12 and the seat cover 14 are pivotally anchored to the housing 22 by the bolts 28. It should be understood that the cover 14 and its corresponding member 54 can be dispensed with or without changing the purport of the invention. Toilet bowls in pubic toilet rooms are generally not provided with seat covers.

BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a side view of a toilet bowl connected to a ventilating system according to the invention, Figure 2 i9 an enlarged view of the encircled portion 2 of figure 1, Figure 3 is a cross-sectional view along line 3-3 of figure 2, Figure 4 is a cross-sectional view along line 4-4 of figure 2, Figure 5 is a cross-sectional view taken along line 5-5 of figure 4, and Figure 6 is an exploded view of the parapet housing and its cover to be connected to a hinge member holding the seat cover of the toilet bowl.
DETAILED DESCRIPTION OF THE DRAWINGS
Figure 1 illustrates a toilet bowl 10 on which is mounted a seat 12 and a seat cover 14 hingedly connected at the rear by a hinge member 16 over the back apron 18 of the toilet bowl 10. The present common practice for securing the hinge member 16 according to the present art consists of bolting the latter to the apron 18 through a pair of apertures 20 which extends through the apron 18. Such apertures 20 are usually fairly large, having a diameter of about 3/8 to 5/8 of an inch which is filled by a large plastic bolt extending through them.
These apertures are used exclusively for locating the bolts which have substantially the same diameter as the apertures 20.
I
One of the essential features of the present invention is to use the apertures 20 as an intermediate portion of the ventilating channel which allows the ventilating piping to be hidden under the apron 18 instead of extending over it. Such astute direction of the air pathway improves the appearance of the ventilated bowl having a ventilating system which are provided with a piping arrangement completely above the apron.
Considering that the present invention can be installed on a conventional toilet bowl and seat cover, the new components can be provided as a kit to be substituted for the present means for anchoring the seat cover and the toilet seat on the back apron.
The assemb]y according to the invention comprises a parapet-like housing 22 having a peripheral wall which is sufficiently elongated to cover both apertures 20. The lower edge of the housing is flat and abuts over the upper surface of the apron 18 and is provided with a forward hooking member 24 to allow the seat 12 and the seat cover 14 to pivot thereabout along a common axle. The housing 22 is provided at both ends with a slot 26 for holding the head of the anchoring bolts 28. The bolts 28 are located to extend down the apertures 20 and through a pair of T-shaped couplings 30 having a vertical and a lateral channel.
The couplings 30 are open at the upper end of their vertical channel to allow the air to pass from the apertures 20 down through the couplings 30 and is closed at their lower ends with perforated plates 32 which allow the bolts 28 to extend thereth-rough. A wing nut 34 serves to tighted the housing 22 to each coupling 30 in solid abutment with the apron 18. The couplings have an opened lateral channel projection 36 extending rearwardly and adapted to be fitted to a piping arrangement 38.
The piping arrangement 38 preferably extends to an adjacent wall of the toilet room in order to reach a ventilating fan 40 hidden from view and possibly sufficiently remote to minimize the sound of the fan.
A cover 42 is adapted to be fitted over the parapet-like housing 22 to define the pathway of the air passage from the toilet bowl 10 to the piping arrangement 38. The cover 42 has two sidewalls 44 and a rear wall 46 fittingly surrounding the corresponding peripheral walls of the housing 22 and a front wall 48 forwardly and spacedly located relative to the corresponding forward peripheral wall of the housing 22. The front wall 48 has a lower edge 50 which is spaced above the upper surface of the apron 18 at a level which allows the air from cavity 51 of the bowl 10 to flow under the seat 12 and extend under the edge 50 and below the upper surface of the cover 42 and down inside the parapet-like housing 22 along the arrow A shown in figure 5. The bolt 28 which has a cross-sectional dimension substantially reduced from the cross-sectional dimension of the aperture 20, allows the air to flow through the arrows B and down into the coupling 30 along the arrow C and into the piping arrangement 38 along the arrow D (see figure 5).
The upper surface of the cover 42 is maintained in spaced relationship with the parapet-like housing 22 so as to allow flowing through the arrow A to meet no hinderence from the cover. The cover 42 is dimensioned to be fittingly surrounding the housing 22 so as to prevent unintentional removing of the cover 42.
The lower surface of the parapet-like housing 22 is preferably designed to be in abutting contact with the upper surface of the apron 18 so as to prevent any water unintention-ally overflowing from the toilet bowl 10 to flow into the housing 22 towards the couplings 30 and the piping arrangement 38. The sl.ots 26 are provided into an inward upper ledge 51 at both ends of the housing 22. Considering that the conventional apertures 20 in toilet bowls are substantially l.ocated at the same distance from one make of bowls to the other, any small adjustment can be taken up by the length of the slots 26.
As it can be particularly seen in figure 3, the location of the bolts 28 relative to the aperture 20, is intentionally located along the periphery of the apertures 20 to prevent the seat 12 and the seat cover 14 to be laterally pushed over the bowl 10. The position of the bolts 28 may be appropriately located inside the apertures 20 along different parts of their periphery according to the shape of the apertures 20 and preferably in their most remote position relative to each other.
Although the present invention has been described with a pair of couplings 30, only one coupling having an elongated shape substantially corresponding to the periphery of the housing 22 can also be contemplated.
As illustrated in figure 1, the fan 40 is located adjacent a rear wall of the toilet bowl 10 to project air through the rear wall 52 along the arrow E. The arrow F in stippled line (figure 1) indicates that the fan could be located, as an alternative, in a forward direction of the toilet bowl 20 up to a nearby wall which may be suitably located for the installation of the fan 40.
As particularly shown in figure 6, the hinge member 16 has two components, that is, a member 54 adapted to be connected to the seat cover 14 and a member 56 adapted to be connected the seat 12. Depending on the hinge member 16 of a particular toilet bowl, the hooking member 24 of the hinge member 16 is connected to be fitted by a pair of coaxial pins 58 so that the seat 12 and the seat cover 14 are pivotally anchored to the housing 22 by the bolts 28. It should be understood that the cover 14 and its corresponding member 54 can be dispensed with or without changing the purport of the invention. Toilet bowls in pubic toilet rooms are generally not provided with seat covers.
