Application April 9, 1954, Serial No. 422,080

9 Claims. (Cl. 4-187) The present invention relates in general to means for mounting items such as sinks in openings in counters or other supporting structures, the primary object of the invention being to provide an improved mounting means for such items. Since the invention may be used for mounting items other than sinks, such as lavatories, electric ranges, etc., it will be understood that the term sink is used broadly herein to cover such other items.

The usual practice in sink installations in residential buildings in particular is to provide a sink opening in a suitable supporting structure, which is customarily a cabinet structure topped by a drainboard, wood ordinarily being used for the drainboard and the cabinet structure. For water-proofing purposes, the drainboard is customarily provided with a suitable covering, such as linoleum, plastic, sheet metal, tile, or the like.

In recent years, it has become the practice to mount a sink in a sink opening in such a supporting structure by a suitable clamping means, the clamping means being engageable with the supporting structure adjacent the sink opening and either being carried by the sink itself, or being a separate device engageable with the sink. While such means of installing a sink works very well where the drainboard is covered with a material such as linoleum, plastic, or sheet metal, it has not been possible heretofore to mount a sink in this manner with a tile covering on the drainboard, one reason being that the clamping means, which is designed to clamp onto the covering material as well as the drainboard, tends to crack the tiling unless the cement used to secure the tiling is allowed to dry thoroughly for several days. A more important reason is that, in laying tile in the contional manner, it is impossible to provide a sink opening having dimensions sufliciently accurate to permit the use of such a clamping means, which requires an accurately dimensioned opening. In view of this, the use of such clamping means for mounting sinks has heretofore been restricted to installations having such drainboard coverings as linoleum, plastic, or sheet metal, and an important object of the present invention is to provide a sink mounting means which permits the utilization of such a clamping means with a tiled drainboard.

More particularly, an important object of the invention is to rim the sink opening with a rigid metallic frame of structural cross section which is secured to the sink supporting structure to provide an accurately dimensioned opening, the clamping means being engageable solely with such frame and not engaging the covering material on the drainboard.

Another object is to provide such a frame formed to fit a particular sink opening.

Still another object is to provide a member of structural cross section having a flange which is notched at intervals proportional to the lengths of the sink edges so that the member may readily be bent into the shape necessary to fit the sink opening.

The foregoing objects, advantages and features of the present invention, together with other objects, advantages 2,752,609 Patented July 3, 1956 and features thereof which will become apparent, may be attained with the exemplary embodiments of the inven: tion illustrated in the accompanying drawing and described in detail hereinafter.

Referring to the drawing:

Fig. 2 is a fragmentary sectional view on an enlarged scale taken along the arrowed line 22 of Fig. 1;

Fig. 3 is a fragmentary sectional view on a further enlarged scale taken along the arrowed line 3?? of i Fig. 4 is an isometric view of an alternative embodiment of the invention prior to forming; and

Fig. 5 is a fragmentary isometric view showing a portion of the embodiment of Fig. 4 after forming.

Referring to the drawing, the numeral 10 designates generally a supporting structure for a rectangular sink 11, the supporting structure 10 adjoining a wall 12 and including a cabinet structure 13 surmounted by a drainboard 14, Fig. 3, in the particular construction illustrated.

The supporting structure 10 provides an opening 16 for the sink 11, the sink opening 16 being rimmed by a rigid frame 18 of structural cross section, the frame 18 preferably being metallic and continuous. In the particular construction illustrated, the frame 18 is an angle section having a vertical flange 20 and a horizontal flange 22 extending outwardly relative to the sink opening 16. The frame 18 is secured to the supporting structure 10, in any suitable manner, as by nails 24 extending throughthe horizontal flange 22 and driven into various components of the supporting structure 18 as required. In the particular construction illustrated, the frame 18 is shown as having been installed before completion of the assembly of the supporting structure 10, various components of the supporting structure 10, such as the drainboard 14, Fig. 3, having been installed on top of the horizontal flange 22. As a matter of convenience, the frame 18 may be of aluminum, in which case the nails 24 may be driven through the horizontal flange 22 without any necessity for drilling holes therefor. However, if a metal such as steel is used, holes for the nails, or other fastening elements, may be drilled therethrough.

With the particular construction illustrated after the frame 18 has been assembled with the various elements of the supporting structure 10 in the manner discussed, the drainboard 14 is covered with tiles 26 in the usual manner, the tiles 26 adjacent the ends of the sink opening 16 being shown as abutting the vertical flange 20 of the frame 18. If desired, cement, not shown, may be introduced between the tiles 26 and the vertical flange 20. Trim tiles 28 are cemented in place along the front edge of the sink opening 16 in the usual manner, any space between the trim tiles 28 and the vertical flange 20 of the frame 18 being filled in with cement to the level of the top of the flange, as indicated at 30. The wall 12 is provided with a tile splash 32, again any space between the tile splash 32 and the vertical flange 28 of the frame 18 being filled with cement to the level of the upper edge of the vertical flange 20, as indicated at 34. The net re,- sult is that the vertical flange 20 of the frame 18 is rimmed with tile and/or cement to, or substantially to, the level of the upper edge of the vertical flange 2!).

While a particular sequence ,of steps has been discussed heretofore for installing the frame 18 and the tiling, it will be understood that the invention is not limited there to, it being possible to install the frame 18 in various other ways and at various other times in the assembly sequence. The net result desired is an accurately dimensioned sink opening rimmed by the frame 18, and it will be apparent that this may be accomplished in ways other than hereinbefore discussed.

Considering now the manner in which the sink 11 is mounted on the frame 18, an illustrative clamping means 36 is provided for securing the sink 11 to the frame 18 preferably without placing any load on the tiling around the sink opening 16, the clamping means 36 preferably engaging only the frame 18 and the sink 11, especially where it is desired to install the sink immediately after tiling. The clamping means 36, which, per se, forms no part of the present invention since it is conventional, is shown as including a T-shaped ring 38 having

flanges

40 and 42 which respecdvely overlie and engage the upper end of the frame 18, i. e., the upper edge of the frame flange 20, and the upper surface of a peripheral flange 44 on the sink 11. The T-shaped ring 38 is provided with a flange 46 which extends downwardly between the sink flange 44 and the frame flange 20 and which is provided with a hook 48 at its lower end. The clamping means 36 includes clamping elements 50 having hooks 52 complementary to and engaging the hook 48 at spaced intervals, the clamping elements 50 having arms 54 which fit under and engage the lower end of the frame 18, i. e., the lower side of the horizontal frame flange 22. The clamping elements 50 also have arms 56 through which are threaded screws 58 engaging the lower side of the sink flange 44. As will be apparent, when the screws 58 are tightened, the sink 11 is clamped to the vertical flange 20 of the frame 18.

In order to provide a seal along the ends of the sink 11, cement may be placed between the tiles 26 and the flange 40 of the ring 38, as indicated at 60 in Fig. 3. If the sink 11 is mounted by means of the clamping means 36 before the cement at 30, 34 and 60 is completely set, a water-tight seal relative to the flange 40 of the ring 38 is provided all the way around the sink. Also, any excess cement is displaced upon tightening of the clamping means 36 when this procedure is followed, thereby insuring that all of the load represented by the weight of the sink 11 is carried exclusively by the frame 18.

It will be understood that the particular clamping means 36 shown is illustrative only and that the invention may be utilized with other clamping means, e. g., one carried directly by the sink. In such a case, the sink flange may rest directly on the frame 18, being secured by clamps carried by the sink flange and engaging the lower side of the frame 18.

While the frame 18 may be preformed to accommodate a particular sink and sink opening, the frame may also be provided in strip form, such a frame being shown in Figs. 4 and of the drawing and being designated by the numeral 64. The frame 64 is also shown as an angle section, although other cross sections may be utilized, the frame 64 having a vertical flange 66 and a horizontal flange 68. The latter is provided with notches 70 therein at intervals proportional to the lengths of the sides of the sink 11 so that the frame 64 may be bent readily at the notches 70 to provide the necessary corners, as shown in Fig. 5 of the drawing. By making the frame 64 of a readily bendable material, such as aluminum, the necessary forming can be done readily on the job without any special tools or equipment, which is an important feature.
