DETAILED DESCRIPTION

(18) Referring to FIG. 18, an assembly 400 for creating an opening in the exterior envelope 402 of a building is depicted. Assembly 400 generally includes frame 108 defining opening 403 and moveable element 404 to selectively close opening 403. Exterior envelope 402 can be a wall or roof of a building. In FIG. 18, the assembly 400 is a window, and movable element 404 is a sash 158, but in other embodiments, assembly 400 can be a door or skylight.

(19) Referring to FIGS. 1 and 2, a self-sealing hinge 100 according to a disclosed embodiment is depicted. Self-sealing hinge 100 generally includes a frame interface assembly 102, a sash leaf 104, and a pin assembly 106. Self-sealing hinge 100 can be adapted to attach to a frame 108 of a window or door.

(20) In one embodiment, frame interface assembly 102 attaches to frame 108 at one or more attachment points 110, and includes a first or frame leaf 112 and sealing member 114. Frame leaf 112 defines a mounting face 116 adapted to attach to the exterior of the frame 118. Frame leaf 112 also defines a plurality of spaced apart knuckles 120. Sealing member 114 defines attachment point liquid barrier sealing face 122 adapted to attach to the interior of frame 124, opposite mounting face 116. In one embodiment, a second or sash leaf 104 defines one or more knuckles 126. Pin assembly 106 includes hinge pin 128 extending through the plurality of spaced apart knuckles 120 and the one or more knuckles 126 to pivotably couple the frame leaf 112 to the sash leaf 104.

(21) A function of self-sealing hinge 100 is to reduce or prevent liquid, such as water, from entering the interior of frame 108 through attachment points 110, when self-sealing hinge 100 is attached to frame 108. Self-sealing hinge 100 is self-sealing and eliminates the need to apply additional silicone during installation, thereby increasing the reliability of weather proofing and improving the efficiency of installation of self-sealing hinge 100 to existing frame 108 or the manufacture of windows and doors employing self-sealing hinges 100.

(22) In addition to the aforementioned benefits, sealing member 114 can also be employed to reduce the thickness (t) of frame 108 at hinge attachment points 110. In hinges of the prior art, the portion of hinge 100 that attaches to frame 108, attaches only to frame 100. By contrast, in an embodiment of the present disclosure, frame 108 is sandwiched between frame leaf 112 and sealing member 114. Accordingly, the profile thickness (t) of frame 108 can be thinner than the prior art, as the frame 108 need not be the sole structure for retaining fasteners 111 at attachment points 110. A reduction in the thickness (t) of frame 108 can reduce the weight, required materials for construction of frame 108, and cost of windows and doors employing self-sealing hinge 100.

(23) Referring to FIG. 3a, sealing member 114 according to a disclosed embodiment is depicted. In one embodiment, sealing member 114 can be constructed out of a lightweight metal, for example aluminum. In another embodiment, sealing member 114 can be constructed out of plastic or rubber. Sealing member 114 can be any shape or size, provided that the attachment point liquid barrier sealing face 122 is positioned proximate attachment points 110, when sealing hinge 110 is attached to frame 108. The surface area of attachment point liquid barrier sealing face 122 can be smaller, larger, or approximately the same size as mounting face 116 of frame leaf 112. In one embodiment, sealing member 114 can include a plurality of indentations 130. In one embodiment, there can be a total of five indentations 130. Indentations 130 can be through-bore holes, blind-bore holes, tapped holes, or untapped indentations.

(24) In one embodiment, sealing member 114 can include gasket 132. Gasket 132 is constructed of a rubber or silicone material. Gasket 132 is configured to surround the plurality of indentations 130. In one embodiment, gasket 132 (FIG. 3b) is configured as a layer on the attachment point liquid barrier sealing face 122. In another embodiment, gasket 132 (FIG. 3c) is integral to and formed as part of sealing member 114. The function of gasket 132 is to reduce or prevent liquid, such as water, from entering the interior of frame 108 through the attachment points 110, when self-sealing hinge 100 is attached to frame 108.

(25) In one embodiment, sealing member 114 includes installation tab 134. Tab 134 may be used when attaching sealing member 114 to frame 108. The function of tab 134 is to assist in the location and positioning of sealing member 114 during installation. Once sealing member 114 is attached to frame 108, tab 134 can be removed. For example, tab 134 can be coupled to the main body 136 of sealing member 114 by a perforated or weakened joint or connection point that can readily break or tear upon a twisting, bending, shear or tensile force, thereby separating tab 134 from main body 136. In one embodiment, tab 134 includes an aperture 138 to assist in the location, positioning, installation, or removal of tab 134.
