BACKGROUND OF THE INVENTION

Field of the Invention

The current invention relates to a diffuser element for skylights. More specifically, the current invention relates to a skylight diffuser frame that itself conveys light.

Description of the Related Art

Skylights provide natural light to the interior of a building by capturing daylight at an exterior roof-mounted cover and conveying that light into a building interior through an interior diffuser element.

The diffuser element is typically mounted at the interior end of the light shaft, upon a building interior ceiling, and includes a lens and a decorative frame. The diffuser lens may be transparent, but more often is translucent. The diffuser lens achieves at least three purposes: (1) it scatters the light entering the room through the skylight into a more aesthetically pleasing array; (2) it conceals the internal structural details of the skylight from normal viewing angles within the building interior; and (3) it provides an attractive interior termination to the skylight. The diffuser frame may conceal irregularities in the ceiling opening that was created to allow passage of the skylight, and it may also provide an ornamental border around the diffuser lens.

Examples of skylight diffusers and diffuser frames are disclosed in the present assignee's U.S. Pat. Nos. 9,702,149 and D793,579, the disclosures of both of which are incorporated herein by reference.

Considering the diffuser frame's proximity to the light within the skylight and the diffuser frame's contribution toward providing an appealing visual element to the skylight system, it would be advantageous if a diffuser frame could further utilize that light to enhance the attractiveness and functionality of the skylight system.

BRIEF SUMMARY OF THE INVENTION

The present invention discovers an elegant additional utilization of the light within a skylight to further increase the attractiveness of the skylight system to occupants of the building interior, by conveying some of that light by the use of the diffuser frame. The present invention offers an improvement upon the known systems for skylight diffuser frames and provides distinct advantages over the conventional systems.

Each example is provided by way of explanation of the invention, and is not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment may be used with another embodiment to yield a still further embodiment. It is intended that the present application include such modifications and variations as come within the scope and spirit of the invention.

Repeat use of reference characters throughout the present specification and appended drawings is intended to represent same or analogous features, elements, or components of the invention.

FIG. 1 illustrates an embodiment of a skylight, generally designated 10, according to the present invention and installed in a building. Skylight 10 includes a cover 20, a light shaft 30, a diffuser lens 60, and a diffuser frame 40. The skylight 10 is illustrated as installed through a building roof 21 and through a building interior ceiling 22. Roof 21 is illustrated in FIG. 1 as inclined, but flat roofs 21 are encountered as well, and the skylight 10 performs equally well with either roof configuration. Between roof 21 and ceiling 22 may reside an attic 23 in some applications, and skylight 10 is illustrated to traverse attic 23 by light shaft 30. In other applications, no attic 23 may be encountered, and light shaft 30 may instead reside between cover 20 and ceiling 22 such as, for example, across the dimension of roof rafters or roof trusses (not shown). In general, light shaft 30 may be understood to be that portion of a skylight 10 that resides between a cover 20 and a diffuser lens 60. Light shaft 30 transports light from cover 20 to diffuser lens 60.

The cover 20 resides on skylight 10 on the exterior of roof 21. Cover 20 as illustrated in FIG. 1 is a dome, but flat covers 20 may be used with the present invention as well. Cover 20 receives exterior light, such as sunlight, and conveys that light into light shaft 30.

Light shaft 30 may be constructed of plaster board, other wallboard, or similar material. Alternatively, light shaft 30 may be made of metal, plastic, and/or other materials. Light shaft 30 may be tubular in some applications.

Light shaft 30 may be understood to have one end, denominated herein as third end 31, located proximate to cover 20 and another end, denominated herein as fourth end 32, located proximate to ceiling 22 and to diffuser lens 60.

Diffuser lens 60 resides at fourth end 32 of skylight 10. Diffuser lens 60 is illustrated in FIG. 1 as planar, and as parallel with the plane of ceiling 22, but other configurations may be used in particular applications without departing from the present invention. Diffuser lens 60 may be transparent or translucent, and diffuser lens 60 conveys light received from light shaft 30 into the interior of the building. Diffuser lens 60 scatters the light received from light shaft 30 into an interior room, conceals internal structural details of skylight 10 from normal viewing angles within the building interior, and provides an attractive interior termination to skylight 10.

Diffuser lens 60 may be carried by, or alternatively may carry, a frame 40. Frame 40 may conceal irregularities in the opening to ceiling 22 that was created to allow passage of the skylight 10, and may also provide an orderly and ornamental border at the diffuser lens 60.

Depending upon user preference, the perimeter of frame 40 may be round, rectangular, or of other shape. For example, if the perimeter of diffuser lens 60 is round, the perimeter of frame 40 may also, but need not necessarily, have a matching round outside perimeter 41. In other applications, depending on user preference or upon other considerations, though the perimeter of diffuser lens 60 be round, the perimeter 41 of frame 40 may be rectangular. Alternatively, in still other applications, depending on user preference or other considerations, though the perimeter of diffuser lens 60 be polygonal, the perimeter 41 of frame 40 may be curvilinear, or vice versa. Similarly, in some applications frame 40 may surround diffuser lens 60; in other applications, frame 40 may only be adjacent to diffuser lens 60 at less than the entirety of the perimeter of diffuser lens 60.

FIG. 2 illustrates a diffuser lens 60 and frame 40, together with a mount 70, according to an embodiment of the present invention. The diffuser lens 60 of the embodiment illustrated in FIG. 2 is shown to reside in a first plane 61. Frame 40 has a perimeter 41 and, in the embodiment illustrated in FIG. 2, is connected to a mount 70. In some embodiments of skylight 10, frame 40 and diffuser lens 60 may be connected to light shaft 30 with a mount 70, mount 70 itself connecting with light shaft 30.

FIG. 3 is a sectional view of certain components of an embodiment of skylight 10. More specifically, FIG. 3 includes illustrations of embodiments of light shaft 30, frame 40, diffuser lens 60, and mount 70.

Further illustrated in the embodiment of FIG. 3 is first plane 61 of diffuser lens 60 and second plane 42 of frame 40; first plane 61 is parallel to second plane 42 in the illustrated embodiment.

In the embodiment illustrated in FIG. 3, light shaft 30 is connected to mount 70 at fourth end 32 of light shaft 30. In turn, mount 70 is connected to frame 40. Frame 40 includes two exemplary light paths 50 within frame 40, specifically light path 50a and light path 50b. Both light paths 50a, 50b may be included in a frame 40, or either may be included singly. Light path 50a includes a first end 51a disposed at light shaft 30 and a second end 52a disposed distal to light shaft 30, at perimeter 41 of frame 40. Light path 50b includes a first end 51b disposed at light shaft 30 and a second end 52b disposed distal to light shaft 30, along second plane 42 of frame 40. Light paths 50a, 50b are conductive of light, from light shaft 30 to second end 52a, 52b respectively. Light paths 50a, 50b may be voids or open pathways within frame 40. Alternatively, light paths 50a, 50b may comprise light conductive material, such as transparent or translucent glass, plastic, polymer, and the like, and blends thereof. Thus, light from light shaft 30 is transported by light path 50a, 50b to second end 52a, 52b respectively, as light path 50a, 50b extend from light shaft 30 toward perimeter 41, and would be visible to an occupant of the interior of a building in which frame 40 is disposed.

FIG. 4 is a sectional view of certain components of another embodiment of skylight 10, including illustrations of embodiments of light shaft 30, frame 40, diffuser lens 60, and mount 70. In the embodiment of FIG. 4, frame 40 itself is light conductive, and can be fabricated from glass, polymer, plastic, or combinations thereof. Thus, frame 40 is light transmissive from light shaft 30 to perimeter 41 and defines a light path 50 from light shaft 30 to perimeter 41. Accordingly, light from light shaft 30 is conveyed by light path 50 from light shaft 30 to perimeter 41, and would be visible to an occupant of the interior of a building in which frame 40 is disposed. With reference to FIG. 4, light within skylight 10 at fourth end 32 would impinge upon first end 51; because frame 40 itself is light conductive, that light is conveyed from first end 51 to, and exits at perimeter 41 from, second end 52, and thereby is visible to an occupant of the interior of a building in which frame 40 is located.

In some embodiments of the present invention, for example that illustrated by FIG. 4, the perimeter 41, which has received light from frame 40 acting as a light path 50, is exposed free of opacity about the entirety of the perimeter 41. Thus, light from the light shaft 30 may be observed at all points about the perimeter 41. In other embodiments, however, light may be blocked or occluded at select locations about perimeter 41, for decorative or other aesthetic purposes.

In the embodiments illustrated in FIGS. 3 and 4, first plane 61 of diffuser lens 60 resides below second plane 42 of frame 40. Alternative embodiments are illustrated in FIGS. 5 and 6. In the embodiment of FIG. 5, first plane 61 resides above second plane 42. In the embodiment of FIG. 6, first plane 61 and second plane 42 reside in the same plane. In the embodiments of FIGS. 5 and 6, frame 40 is light transmissive from light shaft 30 to perimeter 41 and may define a light path 50 from light shaft 30 to perimeter 41. Accordingly, light from light shaft 30 is transported by light path 50 from light shaft 30 to perimeter 41. It will be observed that the embodiments illustrated in FIGS. 5 and 6 provide a frame 40 that is integral with a diffuser lens 60.
