Abstract
Improved frame assembly for doors, windows and the like is provided. The assembly includes a frame defining an opening for receiving and retaining a central panel. The frame is formed from two joined skins which may be molded in the same mold and which are provided with inwardly extending flanges having notched areas on opposite sides of the flanges such that the skins can be joined together to form a lap joint on the exterior edge and to seal a central panel in the opening. Foamable insulating material is provided as a core between the two skins with a separate sealant material provided to seal the central panel. Passage means are provided for introducing the sealant material and the insulating material.
Claims26
An improved frame assembly for doors, windows and the like comprising:
- a frame having an exterior periphery defining first, second, third and fourth edges, the first and third edges being opposite and the second and fourth edges being opposite and having interior edges defining an opening for receiving and retaining a central panel, a central panel positioned within said frame, said central panel defining an edge about its exterior periphery, and frame including a first skin and a second skin in opposed relationship, each of said skins having substantially identical configuration as molded and each of said skins having an exterior edge, a panel portion extending from said exterior edge to a lip terminating at said interior edge, the lips of the respective first and second skins cooperating to define a gap in which the edge of the central panel is positioned, the exterior edges of each skin having first, second, third and fourth exterior flanges depending therefrom and extending inwardly toward the opposing skin, said exterior flanges being joined together to form the first, second, third and fourth edges of said frame, the terminal portion of each of said exterior flanges having at least one notch, said notches being on the exterior faces of said exterior flanges around half of said exterior periphery and on the interior faces around the remainder of said exterior periphery, the dividing points between the notches being on the interior face and on the exterior face being at the mid-points of at least one set of opposing exterior flanges forming (1) the first and third edges and (2) the second and fourth edges, the respective exterior flanges of the upper and lower skins joined together at their respective notches to form a lap joint around said exterior periphery, said skins each having a second inwardly facing flange spaced exteriorally from said interior edges, said second flanges abutting each other and cooperating with the joined exterior flanges and opposed panel portions to form a cavity, and sealant means for sealing the central panel between the lips defining said gap and the abutting second flanges.
An improved frame assembly for doors, windows and the like comprising:
- (i) a rectangular frame having exterior edges defining four sides and interior edges spaced apart from said exterior edges, said interior edges defining an opening for receiving and retaining a central panel, said frame including a first skin and a second skin in opposed relationship, the first skin as molded having substantially identical configuration as the second, each of said skins including:
- (a) an exterior edge having a flange facing inwardly toward the opposing skin, the terminal portion of said flange having one or more notches on each of four sides of the rectangle defined by said flange, the first and third sides being parallel to each other and the second and fourth sides being parallel to each other, one of said notches being on the exterior face of the flange defining the first side of said rectangle from the center of such side to the end adjacent the second side and another notch on the interior face of the flange defining the first side from said center to the end adjacent the fourth side, the opposite and parallel flange forming the third side having a notch on its exterior face from the center of such side to the end adjacent the fourth side and a notch on its interior face from the center to the end adjacent the second side, the flanges forming the second and fourth sides of the rectangle having notches formed on their exterior and interior faces such that the flanges from the second skin and when joined together with the first skin form a lap joint,
- (b) a panel portion extending from said exterior edges to a lip terminating at said interior edges;
- (c) a second flange spaced between the exterior edge flange and the lip and extending inwardly toward the opposing skin, said second flanges abutting each other and cooperating with the joined exterior edge flanges and the panel portion of said skins to form a cavity,
- (d) a lateral wall extending between said exterior edge flange and the second flange at the center of the first of the sides defining said rectangle, said lateral wall abutting the lateral wall of the opposing skin when the skins are joined and having passageway means extending from the exterior edge to a point aligned with said lips for introducing sealing means,
- (ii) a central panel positioned within said opening with its edge extending into the space between said lips,
- (iii) means for sealing the central panel between said lips, and
- (iv) insulating material in said cavity.
An improved frame assembly for doors, windows and the like comprising:
- (i) a rectangular frame having exterior edges defining four sides and interior edges spaced apart from said exterior edges, said interior edges defining an opening for receiving and retaining a central panel, said frame including a first skin and a second skin in opposed relationship, the first skin as molded having substantially identical configuration as the second, each of said skins including:
- (a) an exterior edge having a flange facing inwardly toward the opposing skin, the exterior edge flanges of the second skin joined together with the exterior edge flanges of the first skin to form the exterior edges of said frames,
- (b) a panel portion extending from said exterior edges to a lip terminating at said interior edges;
- (c) a second flange spaced from the exterior edge flange and extending inwardly toward the opposing skin, said second flanges abutting each other and cooperating with the joined exterior edge flanges and the panel portion of said skins to form a cavity,
- (d) a lateral wall extending between said exterior edge flange and the second flange at the center of one of the sides defining said rectangle, said lateral wall abutting the lateral wall of the opposing skin when the skins are joined and having passageway means extending from the exterior edge to a point aligned with said lips,
- (ii) a central panel positioned within said opening with its edge extending into the space between said lips,
- (iii) means for sealing the central panel between said lips, and
- (iv) insulating material in said cavity.
For use in an improved assembly for doors, windows and the like, a skin member comprising a panel portion having first, second, third and fourth exterior edges, the first and third edges being opposite and the second and fourth edges being opposite, said panel portion extending to a lip having an interior edge and defining an opening, each of said exterior edges having flanges depending thereform, the terminal portion of each of said flanges having a notch on its exterior face around half its periphery and a notch on its interior face around the remainder of its periphery, the dividing points between the notches being on the interior face and on the exterior face being at the mid-point of at least one set of opposite flanges depending from (1) the first and third exterior edges or (2) the second and fourth exterior edges, a second flange depending from said panel portion exteriorly from said interior edges and cooperating with said exterior edge flanges to form a channel.
