2 Claims. or. 311-407 This invention relates to counters and to component parts useful in the construction thereof. This application is a division of co-pending application S.N. 571,689 filed March 15, 1956 for Counter Construction.

The demand for counters having surfaces which are durable, attractive, and easily maintained, has resulted in using more elaborate equipment. Presently, factoryfab ricated and site-fabricated units alike most often utilize externally applied polished metal moulding strips of the snap-on type to finish the raw edges. Although economical, external moulding strips represent a source of leakage which can loosen the adhesive bond securing the surfacing sheet and can rot the wooden substructure of a counter. Also, they tend to collect dirt at the line of junction with the surfacing sheet and, in many applications, form an undesirably conspicuous margin around the entire counter assembly. It has, of course, been recognized that metal edge moulding can be eliminated by utilizing some of the surfacing sheet material to cover the raw edge in what is commonly called a self edge. -A liquid-tight, durable self edge has not, however, been attainable heretofore except by the most costly techniques, and in site-fabricated units they are all but unattainable as a practical matter.

Accordingly, it is one object of the present invention to provide improved counter constructions having self edges of pleasingly rounded contour which are both liquidtight and'durable while at the same time capable of simplified fabrication.

Another object of the invention is to provide an improved counter construction, the sub-structure of which can comprise conventional, easily worked, wood panels, and the surfacing of which comprises durable, water-impervious sheet material uniquely integrated with the substructure to form a completed assembly in which unbroken extensions of the surfacing material define the edges.

Another object of the invention is to provide novel substructure form pieces for contouring a counter framework to receive surface sheeting.

In accordance with the present invention,=a series of form pieces for defining respectively the front or leading edge of the counter, the cove between the fiat working surface of the counter, and the upright back splash, and the top edge of the back splash, are provided for attachment to flat panels to become, together with the panels, part of a counter sub-structure defining a smooth, continuous surface to which a single piece of surfacing sheet ates atent material is adhesively attached to integrate the assembly and to provide, if desired, a water-impervious, attractive wear surface altogther free of breaks, cracks, or externally applied marginal mouldings.

The form piece which defines the front edge of the counter can be arranged for application to the horizontal panel in a simple snap fit, with the design being such that once in position and with the surfacing sheet applied, it defines an enlarged, gently rounded edge which is not susceptible of displacement either angularly or in translation. The cove forming piece is designed in accordance with the invention to form a junction between the horizontal and vertical panels and includes surfaces complementary to both panels. In one embodiment, the cove forming piece comprises not only a sub-structure for backing up the surfacing sheet but a bridging link by means of Representative embodiments of the invention are described below having reference to the accompanying drawings in which:

After the adhesive has been aplied the sheet is brought into registry with the substructure and pressed into position, using, for example, the matrix or tool of said copending application to bring the sheet and sub-structure into intimate relationship throughout, the single sheet thereby being bonded to the exposed surfaces of the several panel and form pieces alike.

Another example of a material which can be utilized in conjunction with the present invention, is the so-called C-stage plastic materials of the type comprising laminated sheets, such as, for example, paper woven fabric and matter or Wovens glass fibers impregnated with any suitable thermosetting resin such as phenol urea melamine formaldehyde resins and their derivates including the group of unsaturated polyester resins, e.g., ethylene glycolmaleate acid, polymer modified with monomeric styrene. Such plastics are commercially available as Formica which is the trade mark of a product of the Formica Company of Cincinnati, Ohio, Micarta which is the trade mark of a product of the Westinghouse Electric and Manufacturing Company of Pittsuburgh, Pennsylvania, or Farlite which is the trade mark of a product of Farley and Loetscher of Dubuque, Iowa.

In general, the C-stage plastic laminates cannot be bent to conform with a counter surface such as presently disclosed without the application of heat. Accordingly, where such plastics are utilized it is desirable to pre-form the sheet into the shape of the exterior surface of the counter. After the C-stage plastic sheet has been preformed, suitable adhesives of the type mentioned above are then applied in the same manner as previously indicated. The sheet is then engaged to the counter surface and the matrix applied and clamped in the manner indicated before.

Referring now to Figures 6 and 7, an alternative fabricating technique and a modified cove forming piece are illustrated. A back splash panel 88 can, as preliminary step in the fabrication of the counter, first be disposed in the plane of the horizontal planel 90 and spaced edgewise therefrom for a predetermined distance to receive a flat, unbent sheet 92 of surfacing material, adhesive being applied between the opposed surfaces. After the adhesive has set, the back splash panel 88 is swung into a plane normal to that of the panel 90 by flexing the bridging strip of the sheet material into a generally rounded curvature to define the cove. Next, a reinforced form piece 94 is inserted behind the sheet material at the cove and is secured to both the horizontal and vertical panels. The form piece 94 includes a concavely rounded center wall 96 terminating at its respective ends in reinforced mutually perpendicular shoulders 98 and 101) which abut the edges of the panels 88 and 90, respectively. Marginal flanges 102 and 104 can be formed at the ends of the shoulders 98 and 100 respectively to overlie the panels 88 and 90 and to set the position of the form piece 94 so its curved surface 96 precisely backs up the sheet material 92 at the cove. A barbed flange 106 can be formed on the shoulder 100 to be driven into a suitable channel or groove 108 formed in the horizontal panel 90, after which suitable securing means 110 such as nails, screws, or the like, can be driven into the edge or side, as the case may be, of the back panel 88. It will be seen, therefore, that the form piece 94 serves as both a cove defining member and as a structural link between the two panels.

It can thus be seen that there has been provided a counter which may be easily constructed without the need of expensive tools or machines. Of particular significance is the fact that the counter presents a smooth, continuous, water impervious surface, thereby eliminating the need for exposed moulding strips. As noted above, the use of such exposed moulding strips presents the disadvantage of dirt collection and leakage so that with the counter of the present invention, these disadvantages are efiectively overcome. It should also be noted that the rearwardly extending horizontal flange 54 of the back splash form piece provides an effective means whereby the counter may be installed against a wall so as to insure aleak-proof fit. It is well known that most walls are not precisely flat and include undulations, dips and the like. Heretofore, it has been found necessary to either shape the back splash panel of the counter to the wall or provide caulking between the space between the wall and the back splash panel, which procedures have obvious disadvantages. With the present invention, the counter is initially placed against the wall so that the end of the flange 54 engages the same. The wall is then scored or grooved along the flanged and this scoring is repeated until a horizontal groove is formed in the wall which is suitable to receive the flange with the rear surface of the back splash panel abutting the wall. In this manner, there is provided a horizontal surface which intersects the wall, the horizontal surface being impervious to water and shaped to direct the water downwardly away from the wall. 7

It will be appreciated that various modifications can be made in the invention as described above without in any way deviating from the scope thereof as defined in the appended claims.
