Abstract
A window well structure comprising at least two superposed u-shaped sections made of sheet metal. Engagement means are provided on adjacent edges of the superposed sections which securely interengage each other to unite the adjacent, superposed, u-shaped sections as a unitary, self supporting, integral structure.
Claims5
A window well structure which is to be disposed below the adjoining soil grade adjacent to a window opening in a building wall, said window well structure comprising
- at least two superposed u-shaped sections made of sheet metal;
- and
- engagement means on adjacent edges of said superposed, u-shaped sections which securely interengage each other to unite the adjacent, superposed, u-shaped sections as a unitary, self supporting, integral well structure, said engagement means on the adjacent edges of said superposed, u-shaped sections comprising male and female type engagement members which are formed integrally with and extend substantially along the entire length of the respective edges of said u-shaped sections, with said male type engagement members comprising flat, ribbon-like, elongate sections formed along the mutually respective entire lengths of respective one edges of said u-shaped sections, and with said female type engagement members comprising bent back sections formed along the mutually respective entire lengths of respective other edges of said u-shaped sections such that the respective bent back sections form open u-shaped channels, and further with said female type engagement members in addition comprising sharply bent lips formed along the mutually respective free edges of the bent back sections so that said lips extend downwardly and inwardly into the respective u-shaped channels,
- whereby interengagement between adjacent u-shaped sections is achieved by said male type engagement members being received within said female type engagement members of adjacent u-shaped members, such that said lips on said female engagement members make firm, interlocking, gripping engagement with said male type engagement members along the entire length of said male type engagement members.
Individual sections which when superposed and attached to each other at adjacent junctures form a unitary, integral, self-supporting window well structure which is to be disposed below the adjoining soil grade adjacent to a window opening in a building wall, said individual sections each comprising
- an elongate section of sheet metal which has an upper edge, a lower edge, and two opposite side edges, with said section of sheet metal being formed so that the upper and lower edges and any cross section through said section in a plane parallel to the upper and lower edges have a broad u-shape;
- a male engagement means formed along the entire length of one edge of the upper or lower edges of said section, said male engagement means comprising a flat, ribbon-like, elongate portion formed along the mutually respective entire length of the respective one edge of said section;
- a female engagement means formed along the entire length of the other edge of the upper and lower edges of said section, said female type engagement means comprising a bent back portion of the other edge formed along the entire length of the other edge, wherein the bent back portion forms an open u-shaped channel, and further with said female type engagement means in addition comprising a sharply bent lip formed along the otherwise free edge of the bent back portion, so that said lip extends downwardly and inwardly into the u-shaped channel;
- whereby when two of said sections are superposed in stacked relationship, the male engagement means of one section engages the female engagement means of the second section to unite the two adjacent sections into a unitary, self-supporting, integral structure,
- with engagement of the male engagement means within an adjacent female engagement means being accomplished such that said lip on said female engagement means makes firm, interlocking, gripping engagement with said male type engagement means along the entire length of said male type engagement means.
