8 Claims. (C1. 4-252) This invention relates to a novel adjustable roughing-in adapter or collar suitable for positioning at the discharge outlet lip or pipe of the water closet and useful in the adjustable mounting of the water closet within the conventional bathroom, More particularly, this invention is concerned with an improved adjustment adapter in which the unusual configuration of said collar in cooperation with the outlet lip or discharge of the water closet enables it to be uniquely mounted and .adjustably positioned transversely within the limits of the closet base whereby to easily and conveniently enable a floor mounted Water closet to be installed in properly fitted relationship over the usually fixed plumbing discharge outlet lip leading to the sewage system or to the discharge pipe bend either at the time of the initial installation or, even more importantly, at the time of replacement of the original plumbing fixture and notwithstanding a plurality of roughing-in dimensions specified. As will hereinafter become more readily apparent, the ultimate benefit derived by the manufacturer is to substantially reduce the number of water closets heretofore required to be kept in stock to meet the varying roughing-in dimensions encountered in service.
In order to have a better understanding of the merits of this contribution to the art, it should be appreciated that adjusting adapters are used to adapt the water closet fixture to the varying dimensions encountered in its cooperation with the mouth of the discharge pipe or sewage outlet during the installation and final mounting of the water closet within the room. Heretofore, such prior flanges, collars or adapters have been provided with suit ably slotted portions, the said slots being frequently arcuately extending so that upon suitable rotation of the collar effect the desired cooperation of the adapter with the desired alignment of discharge opening in the base of the closet fixture. In practice, the water closet may be secured by threaded bolts extending through the adapter flange openings and the complementary flange openings of the closet bowl. These types are shown, for example, in US. Patents Nos. 2,899,690, 3,015,501 and 3,125,765, among others. However, these prior designs have not lent themselves conveniently to old installations or remodeling jobs due to the necessity for tearing up the tile or other flooring in an expensive operation in order to make the desired fluid tight connection between the sewage outlet and the water closet.
One of the principal objects, of ,the invention therefore is to provide for an adjusting adapter mountable on or close to the water closet discharge in which either new installations or old ones may be handled more conveniently and economically. In this consideration, it will of course be understood that variations in the dimensional or roughing-in positioning must be allowed frequently from the pre-planned location. Thus, the dimensions of the sewage discharge outlet relative to the base of the fixture must be carefully provided for to assure a sanitary and sturdily mounted installation.
In this connection, it should also be noted that water closet fixtures are designed and manufactured in such a manner that the roughing-in distances between the vertical end wall of the bathroom and the parallel central axis which defines the discharge opening from the water closet are of a certain magnitude. These dimensions are 3,360,805 Patented Jan. 2, 1968 of the order of ten inches, twelve inches, or fourteen inches, and such dimensions taking into account the water closet tank capacity required and the depth or length of the water closet in relation to the said bathroom wall. This depends upon the design employed and the distance, usually established by the builder or architect, of the adjoining wall of the room from the sewage discharge opening, normally located in the floor of the bathroom.
Therefore, it is another important object to provide for an adjusting insert or collar that is easily used in fluid sealing relation to wide dimensional variations in the roughing-in of water closets and which conveniently may be adjustably moved transversely in relation to the necessary alignment with the sewage discharge opening in the building. The latter opening normally has its upper terminus in relatively close proximity to the level of the floor supporting said water closet.
Therefore, it is a further important object to provide for an adjusting plate-like adapter which overcomes all of the previous disadvantages and yet it may be made economically and preferably integrally from a variety of materials, such as porcelain, ceramics, metals and synthetic compositions or the like.
With the adapter of this invention, a single water closet will take the place of three different roughing-in dimensions of water closets, which the manufacturer and his distributors previously have had to stock as will hereinafter be explained.
A still further object is to provide for a relatively sim ple adapter construction which lends itself to making said fluid tight seals easily and without requiring special tools for mounting. Yet it is sturdy and durable to withstand rough handling without breakage when being applied to the bottom or the foot area of the closet bowl.
The novel form of the adjusting adapter also permits of predetermined rotation to obtain the desired adjustment.
With the foregoing and other objects in mind, many of which will further appear as the description proceeds, this invention essentially consists of a novel configuration of water closet adapter in which in the accompanying drawings a preferred embodiment is shown. When considered with such presentation, the invention, its mode of construction, its assembly and operation and many of its advantages not hereinabove specifically referred to should be readily understood and appreciated.
Referring now to the drawings in which the same drawing numerals are used to indicate corresponding or similar parts throughout the several figures of the drawings,
FIG. 1 is a plan view of the novel adapter of this invention;
FIG. 2 is a sectional view taken on the line 2-2 of FIG. 1;
FIG. 3 is a plan view in the structure referred to in FIG. 1 when viewed from the underside thereof;
FIGS. 4, 5, and 6 show the adapter of this invention when mounted in the several positions determined by the central axis of the water closet discharge opening required in meeting variable installations in the field;
FIG. 7 is a view showing the underside of a conventional water closet capable of receiving the novel adapter in the manner shown in FIGS. 4 to 6 inclusive; and
FIG. 8 is a fragmentary sectional View taken on the line $8 of FIG. 7.
Referring now to FIG. 1, the novel collar or adapter of this invention is generally designated 1 and is shown with the upper surface thereof preferably having the recessed portion 2. The latter is defined on its periphery by the upwardly extending flange portion 3, the dotted lines indicating the discharge outlet E of a preferably floor mounted water closet designated WC. Preferably at oppositely disposed side portions thereof, the adjusting adapter 1 is provided with the reduced outer extensions or cars 4 and 5. The latter function as the means for attaching the novel collar to the water closet and to the sewer outlet SO, as hereinafter made clear. The said ribbed areas or outer portions 4 and 5 are formed with the respective relieved or slotted portions 6 and 7 for receiving the attaching bolts 10, shown in dotted lines in FIGS. 4 to 6.
Arcuately extending as shown, the oppositely disposed guide lugsS and 9 are provided for guiding and positioning sealing gasket G as hereinafter described thus to substantially complete the upper surface configuration as shown more clearly in FIGS. 1 and 2.
As shown more clearly in FIGS. 2 and 3, the undersurface of the adapter 1 is provided with the through opening 11 communicating with the water closet discharge E and the depending flange or spud 12 for effecting the fluid sealing connection with the sewage outlet S of the building, as shown more clearly in FIGS. 4 to 6 inclusive and which will be further described in connection therewith. For purposes of supporting the adapter 1 upon the floor FL, the arcuately extending ribs 13, 14, and 15 are provided. Said ribs may of course be of different configurations depending upon the nature of the installation encountered. Thus, the preferred configuration of the novel form of the adapter 1 per se is shown and described in FIGS. 1 to 3 inclusive.
In order to get a better appreciation of the benefits arising in the use of this invention, attention is now directed to FIGS. 4, 5, and 6, in which a water closet WC with adapter 1 applied is shown with the varying required installation centers hereinabove referred to in the description, such as ten inches, or twelve inches, or fourteen inches as designated A, B, and C respectively, the sewage outlet SO fixedly shown with the varying centers above referred to. These installation centers obviously are not readily disturbed once the new building construction has been completed and this of course applies also to old buildings.
The water closet is provided with the usual receptor R and the customary discharge D therefrom communicating with the elongated water closet discharge opening E as shown. Said opening will at all times be within or coincide with the recess 2 of the adapter 1 regardless of the water closet roughing-in dimension required. The limits of the opening E are defined "by the lip P, which is preferably of the same elongated configuration when viewed in plan shown more clearly in FIG. 7.
In the twelve-inch roughing-in water closet position designated in FIG. 4, the usual soft and easily movable gasket G thus is guided and positioned for fluid sealing by means of the arcuate protruding portion 9 at one end thereof and by a portion of the rim defined by the flange 3 at the opposite end thereof. In this arrangement, the water closet is mounted so as to cooperate with the sewage outlet SO. Here, the A dimension is the shortest of the roughing-in dimensions previously referred to, namely, of the order of ten inches. In this relative position, the lowermost flange 12 cooperates with the bell-like flanged opening of the sewage outlet S0. The lower limit of said outlet 12 is mounted in gasketed relation to sewage outlet SO as indicated at L. To complete the assembly, the usual bolts 10 are applied, engaging the slotted portions 6 and 7 of the adapter as shown with the complementarily slotted openings 20 of the closet bowl WC as shown more clearly in FIG. 7. The heads of the bolts 10 at 50 engage the flanged bell portion of the sewage outlet SO, as illustrated, whereby to draw up the fluid tight joint between the gaskets G and L and the water closet WC with the adapter 1 interposed therebetween.
Let it now be assumed that the water closet elongated discharge opening E as shown more clearly in FIG. is to be moved to the roughing-in dimension of say twelve inches as indicated by the letter B. In this construction, showing another position of the novel adapter, it will be noted that the gasket G is now guided in its place as shown by an inner surface on the arcuate projecting portion 8 and at an opposite end thereof on an inner surface of the flange 3. In effecting such transverse movement and positioning of the insert 1 over the sewage outlet SO and relative to the elongated discharge opening E and the lip F of the water closet, the bolts 10 will thus engage the middle set of apertures as at 30 of the said water closet, through slots 6. The bolt-head at 50 engages the flange member SO as shown and described previously. As shown more clearly in the underside view of the water closet base in FIG. 7, it will be noted that the said middle set of oppositely disposed bolt holes 30 are positioned to the right of the first described bolt holes 20. The latter were used for the ten-inch roughing-in positioning of the water closet described in connection with FIG. 4.
Similarly, and as shown now in FIG. 6, let it be assumed that the closet bowl WC is in an adjusted position relative to the wall WL having a roughing-in dimension of say fourteen inches. This is represented graphically by the letter C as dimensionally indicated for said roughing-in figure. Here, also, as previously described in connection with the engagement of the water closet, for the positioning relative to the sewage outlet SO, the bolts 10 engage the next set of elongated openings 40 of the water closet WC as shown. In this particular arrangement, it should be understood that the relative position of the adapter to the water closet is obtained, however, by simply rotating the adapter member 1 around through an arc of degrees in order that the lip F of the closet in this use of the adapter will enable the slots 6 and 7 to be moved transversely to the fourteen-inch roughingin dimension above referred to.
It will, of course, also be appreciated that by merely moving the adapter member 1 in FIGS. 4 and 5 transversely relative to the fixed discharge outlet SO along the floor line FL, a simple and convenient means for effecting desired roughing-in is accurately obtained. Further, as shown in FIG. 6, by rotating the insert member through 180 degrees about its vertical axis from the position shown in FIG. 4, the arcuate projections 8 and 9 will be reversed from their positions illustrated in FIG. 4 to that shown in FIG. 6. Thus, the largest roughing-in dimensions, say fourteen inches, is conveniently accomplished. The bolts 10 as shown in dotted lines in FIG. 6 will engage the apertures 40 of the adapter-abutting water closet WC substantially adjacent the lip F in the manner similar to that described in connection with the previous figures.
It will also be understood that the manner of making the connections at gaskets G and L is easily accomplished by simply placing said suitable soft gaskets around the elongated discharge outlet lip or spud F of the bowl as shown more clearly in FIG. 8. Later in the compressed condition, and when each assembly is respectively made as shown in FIGS. 4 to 6 inclusive, the adapter has provided for the respective ten-inch, twelve-inch, and fourteen-inch roughing-in dimension, as needed. The bolts 10 are tightened as shown.
Regardless of the differences stated in the roughing-in dimension encountered, it will now be apparent that the dimensions A, B, and 0' remain the same, since the adapter of my invention permits such desirable adjustable movement to be easily made relative to the fixed outlet SO as described.
It will also be understood that while the gasket positioning projecting portions at 8 and 9 are preferably employed depending upon the joint or the type and shape of gasket required, the said arcuate projecting portions may in some cases be omitted. In these instances, the recess 2 will of course be made plain and uninterrupted except for flow passage or opening 11.
While only a single adapter embodiment has been shown and described, it will be understood that this is for purpose of illustration, and not of limitation, because to one skilled in the art it will be apparent that various changes and modifications may be made in the disclosure without departing from the spirit of the invention as defined by the appended claims.
