None.
The present disclosure relates generally to the field of window construction. Some window designs include a frame that houses the glazing of the window and a glazing bead that couples to the frame to enclose the glazing and provide decorative features. When the window is installed in a building, the outer glazing bead faces the exterior of the building. Water or other fluids or debris may collect in interior spaces of the frame between the frame, glazing, and glazing bead. It would be advantageous to provide drainage for a window frame with inconspicuous outlets.
One embodiment of the invention relates to an apparatus for a window frame. The apparatus includes a window frame having a lower frame portion; a window glazing supported by the lower frame portion; a glazing bead; and at least two connectors operatively connecting the glazing bead to the lower frame. The connectors are spaced apart defining a fluid pathway allowing fluid to escape from the lower frame.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention as claimed.
These and other features, aspects, and advantages of the present invention will become apparent from the following description, appended claims, and the accompanying exemplary embodiments shown in the drawings, which are briefly described below.

Lower frame portion 12 and side frame portion 14 may be made of wood, a vinyl material, a composite material, a plastic material, an aluminum material, a steel material, an combination thereof, or any other material suitable for a window. As shown in
According to various exemplary embodiments, glazing 18 may include a single pane of glass, double panes of glass, triple panes of glass or any other number of panes. Any space between multiple panes of glass 18 may be filled with air, argon, krypton, a vacuum, or any other substance. Glazing 18 may be made of any type of glass material (e.g., soda lime glass, alkali silicate glass, etc.) of any thickness and may include any features of past, present, or future design (e.g., a low-E coating, lamination, tinting, impact resistance, shatter resistance, etc.) Glazing 18 may also be formed of any other type of window material such as plastic.
A glazing bead 20 is coupled to frame 11 around the periphery of glazing 18. Glazing bead 20 is configured to secure glazing 18 in frame 11 and may also be designed as a decorative trim element to provide a pleasing appearance. Glazing bead 20 may be formed from a material used to form frame 11 such as wood, a vinyl material, a composite material, a plastic material, an aluminum material, a steel material, a combination thereof, or any other suitable material.
According to an exemplary embodiment, glazing bead 20 may include a flexible lip 21 to create a better seal against the surface of glazing 18. Flexible lip 21 may be formed of the same material as the main body of glazing bead 20 and be flexible because of a reduced thickness or may be a different material that is coextruded, applied as a coating, or otherwise coupled to the main body of glazing bead 20.
Glazing bead 20 may comprise several individual elements or may be a single, continuous element that is shaped (e.g., by bending) to extend about the periphery of glazing 18. Referring to the exploded view in

Slots 15 and 25 are sized such that barbs 42 are compressed and otherwise deformed when connector 40 is inserted into slot 15 and/or slot 25. The distortion of barbs 42 when connector 40 is inserted into slots 15 and 25 is resisted by an outward biasing force. The outward force provided by barbs 42 retains connector 40 in slots 15 and 25 and therefore couples glazing bead 20 to frame 11 and to secure glazing 18 in frame 11. The retaining force of barbs 42 is sufficient to overcome opposing forces such as the weight of glazing bead 20, wind, rain, etc. However, the retain force provided by barbs 42 can be overcome by a sufficient outward force, allowing glazing bead 20 to be removed for maintenance or replacement.
While barbs 42 are shown as being generally planar members of a single size and relative orientation, many variations are possible while still providing sufficient force for coupling frame 11 and glazing bead 20. For example, instead of a continuous body extending the length of connector 40, barb 42 may comprise several discrete elements. Barbs 42 may be oriented at a different angle or may have a different cross-sectional shape (e.g., triangular, rounded, etc.). Barbs 42 may vary in size on either side of connector to mate with slots of different sizes in frame 11 and glazing bead 20. Further, barbs 42 may vary in size between the top and bottom faces of connector 40.
The main body of connector 40 and barbs 42 may be made of different materials and integrally formed with a suitable process such as coextrusion. According to various exemplary embodiments, barbs 42 may be made of flexible polyvinyl chloride (PVC), thermoplastic elastomer (TPE), flexible urethane, a rubber based material, or a similar flexible extruded material. According to various exemplary embodiments, connector 40 may be made of PVC, polypropylene, acrylonitrile butadiene styrene (ABS), or any other rigid extrudable material.

Glazing 18 is generally supported above top face 60 of lower frame portion 12 with support structures or spacers. Below the lower edge of glazing 18 is formed an open volume 50 (e.g., space, chamber, cavity, etc.), which is substantially enclosed by lower frame portion 12 and glazing bead 20. Volume 50 is generally defined by glazing 18, glazing bead 20 and top face 60 and wall 72 of lower frame portion 12.
While the seal formed around glazing 18 by glazing bead 20 prevents the majority of water from passing through, moisture may still enter volume 50. For example, moist air may enter volume 50, allowing water to condense in volume 50. A glazing compound 56 is placed between glazing bead 20 and glazing 18 to secure glazing bead 20 to glazing 18. Glazing compound may include other materials and/or tape known in the art including but not limited to silicon compound, one hundred percent silicon, or a hot melt material. Wall 72 prevents water from flowing out of volume 50 into the interior space of the building or enclosure including window 10. Glazing compound 56 is also located between wall 72 and glazing 18. Glazing compound 56 assists in keeping water from entering the interior of the structure as well as from entering the interior of frame regions 50 and 86.
To allow water, other fluids, or debris to exit volume 50, flow paths 54 are formed by the components of window 10. Flow paths 54 are formed by the arrangement of lower frame portion 12, glazing bead 20, and connectors 40 and does not require any additional openings (e.g., channels, holes, slots, etc.) to be formed in components. The weep or exit of flow paths 54 is provided inconspicuously between the lower edge 84 of glazing bead 20 and lower frame portion 12.
According to an exemplary embodiment, flow path 54 is formed between glazing bead 20 and lower frame portion 12. Connectors 40 couple glazing bead 20 to lower frame portion 12 such that glazing bead 20 creates a seal against glazing 18 while maintaining a separation 52 from first wall 62 of lower frame portion 12. Referring to
A second volume 80 is formed between lower frame portion 12 and glazing bead 20 below first volume 50. Volume 80 is generally defined by first wall 62 and first shelf 64 of lower frame portion 12 and glazing bead 20. After flowing out of volume 50, fluids and debris enter volume 80. Glazing bead 20 is coupled to lower frame portion 12 by connectors 40 such that a gap 82 is formed between the lower edge 84 of glazing bead 20 and first shelf 66 of lower frame portion 12. Gap 82 is the only portion of flow path 54 that is visible when window 10 is assembled and installed.
Flow path 54 directs fluids and debris out of the interior of window 10 without entering lower frame portion 12. Fluids and debris are allowed to escape volume 80 through gap 62, flow down second wall 66 of lower frame portion 12, over second shelf 68, down a third wall 70, and escape into the exterior environment. Top face 60, first shelf 64, and second shelf 68 of lower frame portion 12 may be pitched or angled to facilitate the flow of fluids and debris to the exterior space.
Volumes 50 and 80 and flow paths 54 direct any fluids or debris that may collect in the interior of window 10 to the exterior space, reducing the likelihood of damage to window 10 caused by the fluids or debris (e.g., by expansion of freezing water, etc.). The formation of flow paths 54 by the arrangement of components is advantageous because openings formed in components can be obstructed by debris, reducing the ability of fluids to escape volume 50. Further, openings formed in components of window 10 to create flow paths may require additional manufacturing steps (e.g., machining, stamping, etc.), increasing manufacturing time and cost of window 10.
A third volume 86 is located below first volume 50 and second volume 80 and is sealed such that no water is permitted to enter into volume 86. Third volume 86 is formed by top face 60, first wall 62, first shelf 64, a second wall 66, a second shelf 68, a third wall 70, a bottom wall 88 and a fourth wall 90.
For purposes of this disclosure, the term “coupled” means the joining of two components directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally defined as a single unitary body with one another or with the two components or the two components and any additional member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature.
While window 10 is described as rectangular body, in other exemplary embodiments, window 10 and glazing 18 may differently shaped and still include construction that provides an inconspicuous weep. For example, window 10 may be square, another polygonal shape (e.g., hexagonal, octagonal, etc) or rounded. Regardless of the overall shape of window 10, the lower portion of frame 11 and glazing bead 20 may be arranged such flow paths are formed to allow fluids and debris to flow out of the lower portion of window 10.
The arrangement and construction of the frame members and glazing bead for window 10 provides an inconspicuous weep that can be adapted to many other styles of windows. While window 10 is shown in the FIGURES as a picture window frame, in other embodiments, window 10 may be of another construction, such as a casement window, a double hung window, or a bay window.
