  • Patent number: 8418281
    Abstract: An under counter mount sink sealing surface and method of making that provides a watertight interface between an under counter mount sink and a laminate counter as well as a simplified and more dimensionally accurate method of field installing the sink below the counter. The water impervious seal is tightly chemically bonded to the cutout lip of the laminate as well as to the entire area on the bottom face of the laminate countertop that contacts the entire profile of the top face of the under counter mount sink. The seal also aligns the sink into the correct location and contacts the entire surface of the as it is deck aligned or completely parallel to the sink top flange.

  • Patent number: 8245380
    Abstract: A method for undermounting a sink to a countertop includes preparing a countertop and a sink. Thereafter a primary channel is routed within the backside of the countertop, the primary channel including a base and being shaped and dimensioned for receipt of the sink flange, and a secondary channel is routed within the base of the primary channel along an interior circumference of the primary channel. Substrate material is then removed from the secondary channel to expose an underside of the decorative laminate and adhesive is applied within the secondary channel so that the underside of the decorative laminate is fully covered. A bead of adhesive is applied to the base of the primary channel and the sink flange is placed within the primary channel. A support plate is secured around the sink flange to provide support and a central portion of the countertop defined by the primary channel is cut out to expose the bowl of the sink.

  • Patent number: 7007317
    Abstract: This invention deals with a sink having a flange can be flush mounted in a countertop where the countertop is made of a laminate upper layer supported by a wood based body such as particle board. The countertop is readied for sink mounting by ploughing out a sink channel in the supporting body of the countertop. The sink channel is filled with a hardenable plastic such as an epoxy. The upper surface of the epoxy and the laminate is machined such as by a router to create a rabbet to accommodate the flange of the sink. The sink channel is arranged so that the hardened epoxy extends under the laminate so that any water which passes under the flange of the sink will contact the epoxy and not the wood based structure. A faucet having holes to accommodate hot water, cold water, spigot and faucet accessories can be mounted using the same channel and epoxy system.

  • Patent number: 6799336
    Abstract: A sink support shell apparatus and method of making a sink support shell are provided. The sink support shell apparatus is a shell shaped to be compatible with the sink that is to be placed in the sink support shell. The sink support shell includes a rim for mounting the shell either above or below the countertop level. The shell further includes an overflow/vent channel and stand-off in the base for attaching the shell to the necessary plumbing fixtures to allow for drainage of the water from the sink. The overflow/vent channel is formed in the material of the shell and allows water to flow down the channel to be drained by the attached plumbing fixtures as well as air to be vented to reduce suction noise. The sink support shell is made of high-impact material, such as a metal or hard plastic material.

  • Patent number: 6782593
    Abstract: A method of making a flush mountable ceramic sink characterized by having a mouth opening into a planar flange surrounded by an outer rim, the method comprising the steps of: (a) producing a green sink having a base with a mouth surrounded by a lip opposite the base, the lip being surrounded by an outer rim; (b) drying the green sink; (d) firing the green sink; (e) allowing to cool; (g) grinding the lip of the sink flat to form a ground planar flange; (h) grinding away the outer rim at an angle to the planar flange, so that the outer rim tapers from the flange inwards towards the bottom of the sink; (i) applying a post grinding glaze at least to the flange, and (j) firing the post-grinding glaze.

  • Patent number: 6691341
    Abstract: A sink form for use in installing a sink having laterally extending flanges in a countertop is preferably formed of a plastic material, such as nylon or polypropylene resin. It is preferably made to the exact shape of the cut-out opening for the sink, although for round or oval sinks, the form may consist of a flexible strip of the proper cross-section cut to length as required to match the opening. The sink form has a cross section consisting of a downwardly extending portion which is secured to the edges of the opening, a laterally extending flange portion, and, at the outer edge of the flange portion, an upstanding vertical portion terminating in an outwardly curved part. The downwardly extending portion is secured to the edge of the cut-out opening with the laterally extending flange portion spaced away from the countertop to allow for a layer of concrete float material between the flange portion and the countertop.

  • Patent number: 6311345
    Abstract: A method of integrating a basin into a receiving plane, in particular a plane for sanitary fittings or a worktop in a piece of bathroom or kitchen furniture. The method consists in disposing and fixing the basin (3) in an opening in the receiving plane (9) in such a way that the edge of the opening (11-14) is held in a rabbet between the peripheral mouth of the basin (6-8) and a lower shoulder of polymerized resin (19) connecting and caulking the basin and the receiving plane over the entire circumference at the bottom part.

  • Patent number: 6155021
    Abstract: Architectural units having radiused wall corners are constructed with solid surfacing material (SSM) such as Corian. Cove moldings are formed from SSM sheet strips comprising an elongated cove form flanked by elongated rabbet channels. In a table jig, an SSM wall sheet edge is adhesively secured into one of the cove molding rabbet channels. The cove mold and wall sheet unit is secured to the desired architectural wall with the other cove molding rabbet channel mated to an SSM wall sheet edge respective to an adjacent architectural wall. Clamping blocks secured to respective wall sheet and cove mold surfaces by hot melt adhesive are drawn together along the correct vector to adhesively bond each wall sheet edge into a respective rabbet channel.

  • Patent number: 6154893
    Abstract: The bracket is to be installed to the inner face of the peripheral rim of a bathtub, to attach the latter to the inner peripheral edge portion of a fixed casing. The bracket has a rigid head portion which is fixedly attached to the inner rim of the bathtub, and a downwardly depending arcuate resilient foot which carries at its lower end a foot. When installing the bathtub inside the casing and more particularly inside the casing peripheral edge portion, the tub is downwardly displaced until its rim comes into downward abutment against the casing peripheral edge portion, the bracket slidingly abutting against the casing peripheral edge portion with a corresponding resilient foot deformation, allowing the foot to slide under the casing peripheral edge portion and to snap itself thereunder for preventing vertical displacement of the bathtub relative to the casing peripheral edge portion. Indeed, the casing peripheral edge portion is then wedged between the bracket foot and the bathtub rim.

  • Patent number: 4600148
    Abstract: A drainless water cooler or fountain having a gooseneck water dispensing faucet and a waste water receptacle cup mounted on top of the multiply tiered top member. A cup is removably carried within a downwardly depending well which can be retrofitted for readily and economically converting the drainless-type water fountain or cooler into a more permanent drain connected installation. A dual action valve featuring reduced diameter valve seat and valve construction is capable of regulating and dispensing either hot or cold water through the common gooseneck faucet. Placement of the faucet and waste water receptacle cup on the top of the cabinet eliminates the need to bend or stoop when dispensing water or emptying the receptacle cup. The receptacle cup is disposed within the interior of the cabinet and is thus protected against accidental bumping or spilling.
