INVENTOR Robert B. Duggon ATTORNEY United States Patent Ofiice Patented Nov. 22, 1966 3,286,280 CARRIER Robert B. Duggan, Louisville, Ky., assignor to American Radiator & Standard Sanitary Corporation, New York, N.Y., a corporation of Delaware .Filed Feb. 10, 1964, Ser. No. 343,573 16 Claims. (Cl. 4252) This invention relates to a mounting device and method of mounting wall hung plumbing fixtures.
The invention is particularly useful in the hanging of water closets and will be described in relation to such use, it beingunderstood however that the invention'is also useful in handling other plumbing fixtures.
Heretofore, installation of a wall hung plumbing fixture such as a water closet required accurate measuring procedure to locate the proper stud position at which mountings were to be affixed and accurate drilling or notching of the studs for attaching the mounting means. Special tools such as saws, power drills and wood chisels were also required.
According to the subject invention measuring procedure is simplified and special tools areeliminated, asisthe need for drilling or notching studs. v
In one aspect of my invention, mounting ofa plumbing fixture on vertically positioned spaced studs of a conventional building is accomplished throug'hflexible straps connected to acarrier and laid transversely of the studs, the lower straps having depending portions to rest on the sill plates to determine the vertical position of. the carrier. The straps may be maintained temporarily connected in selected position by forming projections on the side of the strap so that such projections may be driven into the stud. Thereafter fastening means may be applied to connect the strap to the stud in a manner to develop a clamping force on the stud when the carrier is connected to support the plumbing fixture, whereby the major weight of the fixture is supported by the clamping action on the stud.
In another aspect of my invention the need for any measurement for vertical position of the carrier is eliminated by predetermined proportionment of the carrier and resting of a lower portion of the carrier on the conventional sill plates of the housing frame.
In still another aspect of my invention, the lower portion of the carrier is provided with vertically adjustable legs to effect correct vertical position.
In a further aspect of my invention lateral positioning of the carrier between the studs is facilitated by the use of shim means, adjustable connections or diverging lower legs as will be described.
It is thus an object of the subject invention toprovide an improved mounting device for installing wall hung plumbing fixtures.
A further object is to provide an'improved method for installing wall hung plumbing fixtures.
Another object is to provide a simple, inexpensive and reliable means for installing wall hung plumbing fixtures.
A still further object is to provide a mounting device and method reducing the time and skill required to install .a wall hung plumbing fixture.
A further object is to provide a mounting device for a wall mounted plumbing fixture which requires no separate measuring means for correctly effecting the mounting.
Another object is to provide in such device means for adjustment to accommodate normal dimensional variations in stud spacing.
Other objects and features of the invention will appear as the description of the particular physical embodiments selected to illustrate the invention progresses, and from reading the accompanying drawings, wherein like numerals of reference indicate similar parts throughout the several views and wherein:

FIGURE 8 is a plan view of a mounting device having upper securing means again modified in accordance with another aspect of my invention and,
.-FIGURE 9 is an enlarged perspective view of a brace element shown in FIGURE 8.
Referring to the drawings, the numeral 2 indicates a carrier positioned vertically in a frame structure between adjacent horizontally spaced and vertically positioned studs 4 and 6 which are mounted on sill plates 8 and 10. The carrier 2 has formed integrally therewith a plumbing connection 12 having one conduit portion 14 for connection to a waste pipe (not shown), another conduit portion 16 for connection to a stack (not shown), and a third conduit portion 18 for connection to a water closet 20 as shown in FIGURE 3.
Extending generally radially and in the direction of the adjacent faces 22 and 24 of the studs 4 and 6 are arms 26, 28, 30 and 32 by which the carrier 2 is connected to the studs 4 and 6 and to the closet 20, as will be described.
The arms 26, 28, 30 and 32 are connected to the studs 4 and 6 by elongated flexible strap members 34. In the embodiment shown in FIGURES 1 to 3 each strap 34 is bent at right angles adjacent one end and formed with integral flanges 36 and 38 to provide rigid right angular braces between which the strap is apertured for bolting to the associated arms 26, 28, 30 and 32. Each of the carrier arms is slotted adjacent its free end as at 40 by which the strap is secured to the carrier arm. The purpose of the slot 40 is to allow lateral adjustment of the brace portion of the strap with respect to the carrier such that one face 37 of the brace rests against the carrierarm and the other face 39 at right angle thereto rests against the adjacent face of the associated stud. This adjustment is desirable to compensate for normal tolerance in spacing of the studs.
It is understood that an elongated slot 40 could be formed in the strap rather than in the associated carrier arm to obtain lateral adjustment. Bolts 42 passing through each strap and its associated carrier arm and securing nuts 43 are used to secure the strap to the carrier.
Referring again to FIGURE 2 it will be noted that the remainder of each strap is sufiiciently long to pass around two corners of the, associated stud and the free end of each strap is fastened to the outer face of the stud. In one form of the strap, the strap is pierced to form on one side one or more projecting portions or tabs 46 which serve when driven into the stud to secure the strap in place or, alternatively to provide an initial temporary securement of the straps during positioning of the same. In the latter case fastenings 44 may be passed through the holes formed by piercing the straps. Since the holding power of the strap on the stud develops mainly from a clamping of the strap on the studs and not from the fastenings, as will be described later, the straps may be secured, as previously mentioned, by the projecting tabs of this type shown in FIGURES 1b to 1 without using separate fastenings such as nails, screws, or the like. These tabs may be readily formed merely by piercing the strap as shown in FIGURES 1b to If. The tabs may be triangular such as shown at 46b in FIGURE 1b, rectangular with pointed or rounded ends as shown at 46c and 46d in FIGURES 1c and 1d respectively, bent over from an edge portion of the strap as shown at 46:2 in FIGURE 12, or bent as shown 'at 46 in FIGURE 1 such that a hammer blow to the bent tab portion will drive the free end into the stud. One or more of these tabs may be used in each strap as required.
The direction of passing the strap around the stud should preferably be in the direction opposite to the force applied to the strap from the carrier under weight of the water closet. Thus, the two upper straps are passed over the rear corners of'the stud and the two lower straps are passed over the front corners of the stud. It will be understood that the straps may be made relatively thin, in the nature of light sheet metal for example, and that the holding power of the straps on the stud develops mainly from a clamping action of the straps on the studs and not from the fastenings.
In the matter of vertically positioning the straps for connection to the studs, an advantageous feature of my invention is that the carrier 2 itself serves as a template by providing depending legs 48 and 50 of predetermined length to properly position thecarrier and itsassociated straps. Thus the straps may be connected to the carrier legs by the bolts 42 and nuts 43 and the carrier isyse't vertically between the studs resting with its depending legs 48, 50 on the adjacent sill plates. The straps may then be moved laterally such thateach brace face engages its associated stud and the straps wrapped around the stud and secured by sinking the strap projections 46 into the studs. Thereafter the fastenings 44, 'if used, may be inserted through the straps and the nuts on the bolts tightened to form a permanent installation. As indicated in'FIGURES 1, 2 and 3 intermediate sections of the arms 26, 28, 30 and 32 areformed with threaded apertures to receive closet bolts 52, 54, 56 and 58 by which the closet 20 is secured to the carrier 2. Suitable lock nuts 60 are provided to abut the carrier 2 and prevent rotation of the closet bolts and suitable stop nuts 62 are provided to cooperate with cap nuts 64 for holding .the closet flange 66 therebetween and against the wall surface. A conventional threaded adapter or coupling and suitable packing is used to provide a water tight seal and connection between the water, closet and the carrier conduit portion 18.
Under conditions of reasonably competent carpentry in the framing of a house, no adjustments of the carrier beyond those described above should be required. However, in the event of unusual circumstances where the framing is considerably out of line, as may be encountered in the replacement of plumbing in a settled house, there may be occasion for adjusting the height of one or the other side of the carrier 2. In such circumstances it may be necessary to insert spacers under one or the other of the depending legs 48, 50. Thereafter the procedure for installing the carrier remains the same with its attendant advantages. It is also contemplated that the depending legs may be formed to accept adapters to be threaded or otherwise adjustably attached to the legs for adjustment of the length thereof. One example of such adapter is shown in FIGURE 1a as an internally threaded member 51 adapted to be threaded on the threaded portion 49 of leg 50 and secured by a set screw 53. Such adapters could then be used on such special installations.
Referring to FIGURE 4 there is shown therein a modification of the invention in which the two lower straps 35 are formed with depending portions 37 of predetermined length to provide proper vertical spacing for the carrier 2. In this embodiment the lower and upper straps are connected to the carrier. The carrier is set in vertical position between the studs 4 and 6 with the strap portions 37 resting on the sill plates 8 and 9 thereby determining the verical position of all four straps. The straps are secured by taping the projections 46 thereof into the studs and, if used, thereafter passing fastenings 44 through the straps and into the studs.
Referring to FIGURE 5 there is shown therein a modification of the subject invention in which lower straps are eliminated and the carrier is provided with lower arms 68, 70 formed with downwardly extending flanges 71 and 72 to engage the front face of the sills 8 and 10. The flanges 71 and 72, which may be fastened to the carrier (by means not shown) or formed integrally with the carrier, as shown, are fixed to the sill plates 8 and 10 by fasteners 74 and 76. In this modification the lower arms 68, 70 are made of predetermined length such that the carrier acts as a template for securing the upper straps and the installation procedure is as described for the embodiment of FIGURE 1.
Referring to FIGURE 6 there is shown therein a carrier secured by a modified form of strap 78 having an aperture adjacent one end for passing a screw 80 or other suitable fastening by which the strap is secured to the carrier.. The strap is passed about two edges of its associated stud and secured thereto as described for the straps of FIGURES 1 and 2.. The carrier in FIGURE 6 is maintained in a desired location between the adjacent studs by'trim members 82 and 84 positioned between the strap and its adjacent stud as indicated. A preferred form of trim member is shown in FIGURE 7 and comprises a plurality of steps with each succeeding step in the direction of the end 86 of the trim member providing a greater width while maintaining surfaces b, c, d and e parallel to the surface indicated at a. With this form of trim member the surface a is placed adjacent the stud and the trim member lowered until a selected surface b, c, d, or e is in engagement with the adjacent surface of the. strap. An advantage of this form of trim member is the maintenance of planar contact on both sides of the trim member and the utility of the steps in preventing the member from passing downwardly between the strap and stud should compression on the member be relieved.
Referring to FIGURE 8 there is shown a plan view of the carrier mounted to the supporting studs in accordance with a further modification of the invention in which separate right angle brace members 88 and 90 are employed. Each brace member such as 88 is formed with an elongated slot 92 adjacent the end of one leg of the brace. The slot may be open at the end as shown in FIGURE 9 or alternatively, the end of the slot 92 may be closed. In this arrangement straps 94 and 96 are each formed with an aperture adjacent one end and the remainder of the strap is passed around the edges of the stud and fixed thereto in the previously described manner. A bolt 98 is passed through the apertured carrier and strap and through the slot 92. The brace is urged outwardly to sandwich portions of the strap between the brace and carrier and between the brace and stud as indicated and a nut 100 is tightened on the bolt. This arrangement produces an adjustable rugged connection of the carrier to the stud and is adapted to low cost manufacturing methods.
It is to be understood that any of the methods described for connecting the upper straps to the carrier may be used with any of the methods described for supporting the lower portion of the carrier. Thus, any of several combinations may be used in accordance with the invention.
It is also to be understood that the connecting conduit shown and described herein as a conventional T may assume other forms and may be separately connectable to the carrier by bolts, set screws or other suitable means to provide flexibility in the form of connecting conduit while effecting standardization of the carrier and securingmeans.
It will be evident. from the foregoing that several advantageous improvements are effected by the subject invention. No special tools are required to install the mounting device. No separate templates are required to effect proper location of the carrier. Means are provided for facilitating lateral adjustment in compensation for normal tolerance in erecting frame members. No drilling, notching or other carpentry is required. The strap connecting means being flexible and relatively thin offer no interference to the installation of sheet rock or wall board, are easily bent into position on the stud, and yet through clamping action on the stud, afford a secure and reliable support means. The device is adapted to low cost manufacturing methods and requires less time and skill to install than conventional mounting devices.
