Description

A BURNER OR TOP OF BURNER THAT INCLUDES A FLAT PANEL LOCKED TO AN EXTERIOR FRAME BY A ENCAPSULATED, MOLDED BY INJECTION, WHICH HAS INTEGRAL FASTENERS BACKGROUND OF THE INVENTION The present invention is directed to a cooker or a burner top that includes a cooker panel or burner top securely secured to an outer frame by a polymeric / copolymeric injection-molded encapsulation. The lining of the frame preferably subtracting at the top a supporting surface, and the encapsulation includes a plurality of integral fasteners each received in an aperture or orifice of a tab of a range, against high or the like. Cookers and burner tops are well known in the state of the art, as evidenced by patents such as U.S. Patent Nos. 4,243,016; 4,453,533; 5,036,831; 5,183,996; 5,185,047; 5,429,114; 5,584,957 and the various patents cited herein, including the patent document of the Federal Republic of Germany (DE 31 10 087). For the most part, these patents disclose a counter-hearth or hearth which includes a polygonal aperture di-insioned slightly larger than that of a glazed ceramic or equivalent panel of a cook top or top burner that is to be mounted on it. A periphery of the counter-hearth or opening generally includes a flange bent downwards with screw holes located at appropriate intervals, representatives of which are illustrated in Figure 1 of U.S. Patent No. 4,453,533. A silicon seal is attached to the peripheral edge of the cooker panel and this silicon seal is adhered to an annular ring of a cross-sectional configuration at right angles as reflected in US Pat. Nos. 5,185,047 and 5,036,831. A series of screws joined with a leg bent down from the annular ring to a flange of the counter, rank or the like through a series of aligned openings having axes arranged horizontally. The disadvantages of such cookers / burner top assembly assemblies have been set forth in the patents immediately noted above and include poor cleaning, lack of a sing aesthetic appearance, additional expense to provide a separate external counter portion, a frame of com assembly to support the glazed ceramic panel, the requirement that the sealant material, sealant or paste material applied between the glazed ceramic panel and the cooker after the glazed ceramic panel is installed in the kitchenette the added material and manufacturing expense associated with these aspects of the kitchen; the preapplication of the sealant followed by curing in the mold, etc. BRIEF DESCRIPTION OF THE INVENTION In regard to the present invention, a cooker panel or a burner top panel is inserted into a mold in internal relation to a counter frame ring, or frame counter frame. The mold is surrounded to form a peripheral cavity that accommodates an innermost peripheral edge of the counter frame ring and an outer peripheral edge of the panel. The polymeric / copolymeric material is injected into the cavity and subsequently cooled to join the counter-frame ring to the kitchen panel. The peripheral edge of the copier panel can be first primed to achieve maximum adhesion between the cooker panel and the solidified or encapsulated injection molded material, but this is not a requirement of the invention. The frame of the counter frame may also include a series of openings with which the encapsulation is locked when the solidification is carried out. Finally, the encapsulation includes integral injection-molded "Christmas tree pin" fasteners, which are fastened in openings of a counter-flange or a flange flange to attach it to the cooker / panel panel of the cabinet. Burner Top The encapsulation process immediately above mentioned essentially integrates the lining ring and the cooker panel or burner top panel through the encapsulation with portions of the encapsulation defining integral fasteners to join the cooker panel / top of burner to a counter, stove or the like. A stove or burner top manufactured in this way can be installed without the need for tools, can be easily removed without the need for tools, and 1 appearance, especially when associated with a counter-hearth or stove, is extremely aesthetic, easily cleanable, and is essentially free of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a partial perspective view of a new cooker, burner top or the like of the present invention, and illustrates an intertrawed flat polygonal kitchenette panel attached to a peripheral frame or frame ring by a molded encapsulation by injection which is in turn attached to a horizon eyebrow defining an opening of a fire or counter-attack. Figure 2 is an enlarged cross-sectional view taken along the line 2-2 of Figure 1, and illustrates details of the encapsulation including one of a plurality of dependent "Christmas tree" junctions, intertwined in an aperture of a horizontal eyebrow of the stove, counter or similar support. Figure 3 is a perspective view similar to Figure 1, but illustrates an encapsulation that includes a leg projecting upward in sandwich between the opposite peripheral edges of the cooker panel and the frame ring. Figure 4 is a cross-sectional view taken along line 4-4 of Figure 3, and illustrates specific details of the encapsulation and a seal ring carried by the frame ring.

The kitchenette 50 includes a chambered ring or garrison or chambered frame or lining 60 of a generally polygonal configuration having a substantially T-shaped cross-sectional configuration defined by an outermost arm portion 61, a peripherally innermost short arm portion 62 and a dependent leg portion. substantially vertical 63 having a plurality of holes or openings 64 formed therein. A lower surface 65 of the arm portion 61 subtracts from the support 13 'arranged substantially horizontally while the lowermost surface 65 of the arm portion 62 rests on an upper (unnumbered) surface of an encapsulation 70. arm portion 62 of the chambered ring or gasket 60 is spaced from the edge 54 of the kitchen panel 51 to define a peripheral gap 80. The encapsulation or encapsulation means 70 is substantially one piece, homogeneous, injection molded, of material polymer / copolymer which secures the peripheral edge portion of the kitchenette panel 55 of the cooker 50 to the chambered or garrison ring or frame or gasket 60 through an injection molding process similar to those disclosed in the above patents cited. Essentially, the panel or plate 51 and the chambered or garrison ring or frame or garrison 60 are located in a mold in the relative position illustrated in FIG. 4 with the mold bodies include a cavity (not shown) surrounded to form the encapsulation injection molding 70 including integral injection molded means in the form of "Christmas trees" projecting downward or resembling joints 72. During the injection molding process, as is evident from the aforementioned patents, the polymeric / copolymeric material also flows into the numerous openings 64 of the dependent leg portion 63 of the chambered ring or lining 60, solidifies and defines means generally identified by the reference numeral 85 to interlockably secure the chambered ring or lining 60 to the panel of kitchenette 51 in the solidification of encapsulation 70. During the process of molding by i njection, the polymeric / copolymeric material flows into the interstice 80 and also solidifies therein. The encapsulation portion 70 in the interstice 80 de-finishes a more superior (unnumbered) surface by forming a substantially smooth coplanar transition in and between higher (unnumbered) surfaces of the 51 panel of the kitchenette and the short arm portion 62 of the chambered or garnished ring 60. Preferably, but not necessarily, the surfaces 52, 53, and 54 of the outermost peripheral edge portion 55 of the kitchenette panel 51 can have a first application of this, as disclosed in the patents above. mentioned, such as first Che lok EP6962-50A / B, each manufactured by Lord Corporation, 2000 West Grand View Boulevard, PO Box 10038, Erie, PA 16514-10038. The latter increase the adhesion between the peripheral edge portions 55 of the Ceran® 51 panel and the encapsulate 70 which preferably is Santoprene® manufactured by Advanced Elastomer Syst / ems L.P. The arm portion 61 of the chambered ring or liner 60 includes a channel (unnumbered) which opens through the surface 65 and receives a 0-ring seal or seal means 90 for sealing against an upper surface (unnumbered) of the 13 'support. After the encapsulation 70 has solidified, the mold is opened, the kitchenette 50 is removed from there and shipped to the end user, such as a stove manufacturer. The assembly of the cooker 50 and the associated cooker 10 'is simple and direct, that is to say, the cooker 50 is aligned with the opening O' of a cooker 10 ', counter-head or the like and the projected integral joints 72 are forced downwards. each within the openings 16 'while the components are completely assembled in the manner illustrated in Figure 4.
