This invention relates to improvements in mountings for installing a peripherally rimmed member, such as a fiat flange type sink, or the like, in an opening in a drainboard, cabinet top or like supporting structure.

It is a general object of the invention to provide an improved mounting means which is particularly adapted for rigidly securing a flat flange type sink or similar peripheral flanged member in an opening in a drainboard, cabinet top or similar supporting structure, and providing a tight seal between the adjacent edges of the flanged member and the supporting structure.

It is a more specific object of the invention to provide A a mounting for a sink or other member having a peripheral flange which comprises a sealing frame having a top portion which covers the space between the edge of the sink and the supporting structure by overlapping engagement with the adjoining top surfaces thereof and the web portioniwhich depends between the edge of the sink and the wall of the supporting structure which defines the opening therein, together with a plurality of cooperating clamp-like fastener elements or lugs having interlocking ,engagement with the web portion of the sealing frame adjacent the bottom edge thereof, which fastener elements have laterally projecting end portions with one of the end portions provided with an adjustable clamping means for clamping engagement with the sink flange and the other having a pointed edge for penetrating engagement with the adjacent wall of the supporting structure.

It is a further object of the invention to provide a mounting for a flanged sink or similar member which compr e Hea ng r me hav ng t p flange forming portions adapted to extend over the space between the edge o the. sink an t djoi u a o t supp r ing strueture and a web portion adapted to depend between the sink and the wall of the supporting structure which defines the opening therein, and a plurality of cooperatn lamp n el en h v n p a n a e e t w t the web portion of the sealing frame adjacent the lower d e he eo wh c c mp eme t hav l te y projecting portions with an adjustable clamping means in one i s id a a Po ons f r l mp n en a em n with the frame and with the other of said lateral portions having apointed edge formation extending towards the adjacent wall of the supporting structure for penetrating engag ment with t m p i s meht of he damning'means to pivot the clamp about the Web portion of the frame whereby the sink may be readily mounted in v a. supporting structure in which the wall. around the opening is relatively deep so that the lower surface of the supportingstructure around the opening is at a level too far belowthe sink rim to permit of its engagement by the clamping elements.

It is a still further object of the invention to provide a sink and drainboard mounting in which a T-shaped board'to rigidly secure the sealing member in such relaw 2,864,099 Patented Dec. 16, 1958 "ice tion and to provide a water tight seal between the sink and the drainboard, the clamping members each being detachably and pivotally connected intermediate the ends thereof to the sealing member and having a surface penetrating formation on the one end thereof which isswing able into engagement with the wall of the drainboard defining the opening therein by operation of a clamping element on the other end thereof which is engageable in clamping relation with the underside of the sink rim.

It is another object of the invention to provide a mounting means of the type described wherein clamping elements or lugs are provided with a clamping screw which has a pressure spreading formation on the end thereof which is adapted to be engaged beneath the flange of the member which is being mounted in the opening in the supporting structure.

These and other objects and advantages of the invention will be apparent from a consideration of the forms of the invention which are shown by Way of illustration in the accompanying drawings wherein:

Fig. l is a top plan of a sink installed in a drainboard which embodies therein the principal features of the invention;

Fig. 2 is a section to an enlarged scale taken on the lines 22 of Fig. 1, and showing the mounting as initially assembled with the sink and the drainboard prior to clamping the sink in position in the drainboard aperture;

Fig. 3 is a section as in Fig. 2 with the sink clamped in its final position and the pointed ends of the clamping element in penetrating engagement with the wall of the drainboard;

Fig. 4 is a perspective view to an, enlarged scale of one of the clamping elements;

Fig. 5 is a section similar to Fig. 3 showing the mounting means employed with a member having a peripheral flange of relatively thin material; and

Fig, 6 is a section similar to Fig. 5 showing a modified form of pressure distributing means employed with the clamping element.

In the preferred form of the invention, as illustrated in Figs. 1 to 4 of the drawings, mounting members or fixtures are provided for securing a sink 10 in position in an aperture or opening 11 which is provided in a drainboard 12. The illustrated sink 10 is a standard type having an outwardly directed top flange or rim 13 while the drainboard may be a conventional plyboard construction having a top of linoleum or other similar material 14. In the drainboard which is shown the opening 11 is defined by a vertical wall 15 which is of substantail depth due to more than the usual thickness of material in the drainboard or due to the presence of cleats or other reinforcing elements which may be positioned around the periphery of the opening, the mounting means of the invention being particularly adapted for use in the installation ,of a sink or like structure in an opening of this character, having a surrounding wall of greater depth than ordinarily encountered, but not being limited, however, to such installations.

The sink mounting means comprises an integral sealing ring or frame 16 and a plurality of cooperating fastener elements or clamping lugs 17. The sealing ring or frame 16 which may be formed from bent plate metal as shown or which may be a solid section, is substantially T-shaped in cross section as shown in Figs. 2 and 3 to provide a top portion 18 having laterally extending

flange formations

19 and 20 and a depending stem portion 21. The

top flange formations

19 and 20 are adapted to extend over the top surface of the drainboard 12 and the adjoining surface of the rim 13 of the sink 10 when the sealing ring 16 is positioned with the stem 21 depending between the opposed edges of the drainboard 12 and the along its lower edge with a continuous hook formation 22 which provides an upwardly and inwardly facing shoulder 23 for interlocking engagement with a cooperating portion of the clamping or fastening members or elements 17.

The clamping lugsor fastening elements 17 (Figs. 2

to 4) are of inverted T-shaped cross section and each comprises a plate-like base 24 as shown in Fig. 4 having a relatively short upstanding stem 25 provided on its upper edge with a hooked end formation 26. The base member 24 comprises end portions 27 and 28 extending laterally with respect to the upstanding stem member 25. The hooked end 26 of stem 25 is adapted to be engaged with the hook formation 22 on the downwardly extending stem portion or leg 21 of the sealing ring 16 as shown in Figs. 2 and 3. The base member 24 of fastener element 17 is adapted to be positioned so that the laterally extending end 27 projects beneath the sink flange 13 and is provided with a threaded aperture 29 and a clamping means which is in the form of a flat head machine screw 30 adapted to be positioned with its end engaged against the under surface of the flange 13 of the sink 10. The other laterally extending end 28 of the base member 24 is formed with its bottom surface tapered at 31 to provide a relatively thin terminal or end edge which is cut away in the center at 32 and provides two relatively sharp spaced projecting point formations 33 and 33'. The pointed end 28 of the base member 24 is adapted to be positioned initially in opposed relation to the vertical wall of the drainboard 12 as shown in Fig. 2

and so that when the clamping screw 30 is taken up sufiiciently to pivot the fastener element 17 about the hook formation 22 on the depending web 21 of the sealing frame 16, the pointed portions 33, 33' of the fastener element 17 will penetrate the wall 15 of the drainboard 12 and firmly anchor the fastener relative to the drainboard 12 and the sink 10. The fastener element 17 may, of course, be stamped from a metal plate, or cut from an extruded metal section as shown, or formed in any other manner from any other suitable material.

In installing a flanged sink or similar member in an opening in a drainboard with the mounting illustrated in Figs. 1 to 4, the sink 10 is positioned in the opening in the drainboard and temporarily supported in any suitable manner, such as by adjustable corner supports indicated at 37 in Fig. 1, while the sealing frame 16 is positioned around the same. A plurality of fastening elements 17 are then positioned in spaced relation on the frame 16 with their hooks 26 in engagement with the hook formation 22 thereof, as illustrated in Fig. 2, and with the end 27 of the base portion extending beneath the rim 13 of the sink 10. The clamping screws 30 are than taken up until they pivot the fastening elements 17 sufficiently to engage the pointed ends 33, 33 thereof solidly in the surface 15 of the drainboard 12 and clamp the ring 16 in tight engagement with the top surfaces of the drainboard 12 and the rim 13, thereby clampingthe sealing ring 16 and the sink 10 securely to the drainboard 12 as shown in Fig. 3.

The sealing ring 16 and the clamping or fastening elements 17, as illustrated in Figs. 1 to 4, are provided with the interengageable hook members 22 and 26 to obtain the separable pivotal connection between the same, but it will be understood that this construction is merely illustrative and that other pivotal constructions may be used to provide for the pivotal movement between these members. Also, the wall engaging end 28 of fastener element 17 is shown with two laterally spaced surface penetrating points 33, 33' but a smaller or greater number of point formations may be provided thereon with the point or points being relatively sharp so that they will readily dig into or penetrate the wall surface.

Referring to Figs. 5 and 6, the mounting means is illustrated as employed in securing in an opening 11 in a drainboard or other support 12, a member having a top peripheral flange of relatively thin material, such as a range unit 40, which has a relatively thin metal top rim or flange 41. In this assembly the sealing frame and clamping elements are identical with the corresponding members shown in Figs. 1 to 4. The range unit 40 is temporarily supported in the opening 11 and the frame 16 and fastener elements 17 are initially positioned in spaced relation around the same with the depending stem 21 thereof in the space between the wall 15 of the opening 11 and the oppositely disposed vertical wall 42 of the range unit 40, and with the

top flanges

19, 20 of the frame 16 engaging the top surfaces of the flange 41 and the support 12 in the same manner as in Fig. 2.

The fastener elements 17 are provided with a modified clamping screw 43 which is arranged in the threaded aperture 29 of the fastener element 17 with its head 44 in engagement with the under surface of the thin metal flange or rim 41 of the range unit 40. The threaded end of the screw 43 is provided with a kerf or slot 45 for accommodating the blade of a screw driver or other turning tool. As the screw 43 is taken up to pivot the fastener 17 about the stem 21 of the frame 16 and cause the pointed end 28 thereof to dig into solid penetrating engagement in the supporting wall 15 the head 44 spreads or distributes the pressure on the flange 41 over a substantial area and prevents damage to the flange 41, while insuring a tight clamping action.

In the assembly illustrated in Fig. 6 the clamping screw 50 which is employed with the fastener element 17 is provided with a modified pressure distributing means. In this form of the assembly the sealing frame 16 and the fastener elements 17 are identical with those shown in Fig. 7 and the positioning thereof with the range unit 40 and the 'apertured support 12 is the same. The screw 50 is provided with a conventional slotted head 51 at one end and at the other end which abuts the undersurface of the flange 41 with a pressure distributing member 52. The member 52 is in the form of a strip of metal which is bent into a U-shape with an aperture 53 provided in the one leg thereof for receiving the threaded stem of the screw 50 so that the end of the latter engages the lower surface of the opposite leg which is positioned in engagement with the under surface of the flange 41. The pressure spreading member 52 is formed of hardened material so that it spreads the pressure applied by the end of the screw 50 over a relatively wide area of the flange 41. This arrangement insures a tight clamping action and prevents the flange 41 from being dented or showing the outline of the pressure area of the screw end when the installation is completed.

While particular materials and specific details of construction have been referred to in describing the forms of the invention which are illustrated in the drawings, it will be understood that other materials and other details of construction may be resorted to within the spirit of the invention.
