Description




FIELD OF THE INVENTION




The present invention relates generally to connectors for tubular skylights.




BACKGROUND




Tubular skylights have been provided for illuminating the interiors of buildings in an aesthetically pleasing and energy efficient way with natural sunlight. An example of a commercially successful skylight is disclosed in the present assignee's U.S. Pat. No. 5,099,622, and further examples of effective tubular skylights are disclosed in the present assignee's U.S. Pat. No. 5,896,713 and in allowed U.S. patent application Ser. No. 09/126,331, all of which are incorporated herein by reference.




In tubular skylights such as the those mentioned above, a transparent plastic dome is mounted on a roof of a building by means of a metal flashing that is attached to the roof. Extending down from the dome is a metal tube that has a highly reflective inner surface. The tube extends down to the ceiling of the interior room sought to be illuminated, where it terminates at a disk-shaped light diffuser mounted on the ceiling by means of one or more support rings that engage the lower end of the tube.




It will be appreciated that with the above general description of tubular skylights in mind, many components must be connected together. As but one example, the tube itself is ordinarily made from a flat sheet of metal that is bent into a cylindrical shape to form the tube, with the opposite ends of the sheet of metal slightly overlapping each other in the cylindrical configuration and being held in the cylindrical configuration by manually taping the length of the joint between the ends of the bent sheet. As understood by the present invention, while effective, the above-mentioned manual means for forming the tube can result in tubes having diameters that might exhibit deviations slightly from design. Moreover, it is sometimes desirable that the tube slightly taper, i.e., assume a slightly frusto-conical shape, and it is difficult to precisely configure a tube to have such a shape using the manual taping method described above. Fortunately, the present invention recognizes that it is possible to easily and with a high degree of repeatability effect a precisely-configured skylight tube.




As another example, consider the connection between the plastic dome and metal flashing. A metal screw is advanced through an ABS washer that is positioned in a hole in the dome, and the screw engages the metal flashing. As recognized herein, the washer can sometimes undesirably rotate in the hole of the dome, thereby rendering it less than optimally effective as a connection interface with the screw and, hence, the flashing to which the dome is mounted.




As yet other examples, connecting the diffuser and the various support rings to the lower end of the tube and to the ceiling must be accomplished in relatively confined areas, and accordingly can be a cumbersome and time-consuming task. The present invention understands that such connections can be effected quickly and securely by the novel connecting systems and methods disclosed herein.




SUMMARY OF THE INVENTION




A light transmitting member for a skylight includes a sheet defining opposed axial edges. The sheet can be bent into a light transmitting configuration, wherein the axial edges are juxtaposed with each other and a light transmitting channel is established by the sheet. First and second sets of axially spaced tab elements are formed along respective axial edges of the sheet. A first tab element in the first set includes a tab while a second tab element in the second set defines a tab opening. As disclosed in detail below, the tab is movable between an engage configuration, wherein the tab can be received through the tab opening, and a lock configuration, wherein the tab cannot be removed from the tab opening to thereby hold the sheet in the light transmitting configuration. Indeed, at least upper and lower tab elements include respective tabs and respective tab openings, and the tab of each tab element in a pair is receivable through the tab opening of the other tab element in the pair.




In a preferred embodiment, each set of tab elements includes at least two tab elements. The tab elements in the first set are juxtaposed with respective tab elements in the second set when the member is in the light transmitting configuration to establish plural tab element pairs. Each tab element is integral to the sheet, i.e., the sheet is cut to form the tabs, with the tabs being retained on the sheet by an uncut living hinge.




Furthermore, the sheet is formed with at least two upper tab elements in each set of tab elements. The upper tab elements of one set are axially and radially spaced from each other to facilitate selectively establishing one of: a frusto-conical shape, and a cylindrical shape, of the sheet in the light transmitting configuration.




In another aspect, a method for forming a skylight tube includes providing a sheet defining first and second opposed edges, and forming plural tabs along at least the first edge and forming plural tab openings along at least the second edge. The method further includes advancing the tabs through respective tab openings with the sheet in a light transmitting configuration. Then, the tabs are bent to hold the sheet in the light transmitting configuration.




In yet another aspect, a skylight tube includes a sheet having a reflective surface. Fasteners are formed integrally on the sheet. The fasteners can be moved to hold the sheet in a light transmitting configuration, wherein the reflective surface is an inside surface.




In another aspect, a skylight dome fastener adaptor includes a hollow body defining an outer surface. Plural ribs are formed on the outer surface and are configured for engaging a hole in a skylight dome in an interference fit to impede rotation of the body in the hole.




In still another aspect, a lower skylight assembly includes a skylight dress ring that has a vertical flange formed with at least one clip hole. A skylight support ring has a vertical flange closely spaced from the vertical flange of the dress ring and terminating in a horizontal flange defining a ratchet aperture. Per present principles, a zip clip has an elongated body defining opposed first and second elongated surfaces, and a clip protrudes from one of the surfaces and is received in the clip hole of the dress ring. Also, at least one of the surfaces of the zip clip is formed with ratchet structure that engages the ratchet aperture of the support ring to thereby hold the dress ring onto the support ring.




In yet another embodiment, a zip tie has an elongated body defining first and second ends. A ratchet structure is formed on the body. Moreover, a clip arm is attached to and extends perpendicularly away from the first end of the body. Still further, the clip arm defines a channel. The channel is configured to receive a threaded fastener in self-tapping threadable engagement.




The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring initially to

FIGS. 1 and 2

, a light transmitting member is shown, generally designated


10


, for transmitting light from a roof-mounted plastic transparent dome


12


to a ceiling-mounted diffuser plate


14


. As disclosed in detail below, the member


10


can be formed in a cylindrical configuration or in a slightly tapered, i.e., frusto-conical, configuration to establish a skylight tube.




As shown in

FIG. 1

, the member


10


includes a metal sheet


16


that defines opposed axial edges


18


,


20


. When the sheet


16


is bent in the light transmitting configuration shown in

FIG. 2

, the axial edges


18


,


20


are closely juxtaposed with each other and indeed overlap each other. In the light transmitting configuration, the sheet


16


defines a light transmitting channel


21


that is bounded by an inside surface on which is disposed a reflective coating


22


, to render the inside surface highly reflective.




In accordance with the present invention, to provide a means for holding the sheet


16


in the light transmitting configuration shown in

FIG. 2

, fasteners are formed on the sheet


16


. More specifically, first and second sets


24


,


26


of tab elements, generally designated


28


, are formed integrally in the sheet


16


along respective axial edges


18


,


20


, as best shown in FIG.


1


. The tab elements


28


in a set accordingly are axially spaced from each other. More specifically, each set


24


,


26


of tab elements includes two upper elements


28


as shown, two lower elements


28


, and a single middle element


28


, although other element patterns can be established in accordance with present principles. In any case, as can be appreciated in reference to

FIGS. 1 and 2

, the tab elements


28


in the first set


24


are juxtaposed with respective tab elements


28


in the second set


26


when the sheet


16


is in the light transmitting configuration, to establish plural tab element pairs for purposes to be shortly disclosed.




In the second set


26


of tab elements, the elements


28


are colinear with each other as shown in FIG.


1


. Also, in the second set


26


, the two upper and two lower tab elements


28


each include a respective tab


30


formed by a cut in the sheet


16


around three sides of the tab


30


, with a fourth side of the tab


30


being uncut and consequently establishing a living hinge


32


about which the tab


30


can be pivoted. The free end


34


of each tab


30


, i.e., the end opposite the respective living hinge


32


, can be rounded as shown for safety. When the tab


30


is pivoted away from the sheet


16


, a tab opening


36


is established as shown best in FIG.


1


. If desired, the tab of the middle tab element


28


M in the second set


26


can be removed, such that the middle element


28


M consists of a permanent aperture as shown in FIG.


1


.




The tab elements


28


in the first set


24


are essentially identical in construction and operation to the tab elements


28


in the second set


26


shown in FIG.


1


and described above, with the following exceptions. The top-most element


28


T, middle element


28


N, and bottom-most element


28


B are axially aligned with each other as shown. On the other hand, a second top element


28


TS that is closely spaced from the top-most element


28


T and second bottom element


28


BS that is closely spaced from the bottom-most element


28


B are axially aligned with other and are slightly axially and radially spaced from the top-most and bottom-most elements


28


T,


28


B, respectively. The middle element


28


N of the first set


24


of elements includes both a tab and a tab opening as shown.




With the above disclosure in mind, it may now be appreciated that the tab


30


of the top-most element


28


T in the first set


24


can be moved about its respective living hinge


32


to an engage configuration, wherein the tab


30


extends radially outwardly from the sheet


16


and the tab


30


can be received through the tab opening


36


of the corresponding tab element


28


in the opposite set


26


. Also, the tab


30


can be moved to a lock configuration, wherein the tab


30


is folded back away from the opening


36


in which it is received to overlap the sheet


16


, such that the tab


30


cannot be easily removed from the tab opening


36


(without bending the tab) to thereby hold the sheet


16


in the light transmitting configuration. Likewise, the tab


30


of the middle element


28


N in the first set


24


can be engaged with the middle element


28


M of the second set


26


, and the bottom-most element


28


B of the first set


24


can engage the corresponding element in the second set


26


of tab elements. It is to be understood that the tabs


30


in the second set


26


can be likewise interlocked with tab openings


36


in the first set


24


of tab elements. In the example above, the second top element


28


TS and second bottom element


28


BS are not used, and a skylight tube is provided that has a cylindrical configuration and a maximum diameter.




It is to be further appreciated that instead of using the top-most and bottom-most elements


28


T,


28


B, the second top element


28


TS and second bottom element


28


BS can be used in conjunction with the middle element


28


N of the first set


24


, thus providing a skylight tube with a cylindrical configuration and a minimum diameter. Still further, a skylight tube can be provided that has a slightly frusto-conical shape by using the top-most element


28


T, middle element


28


N, and second bottom element


28


BS of the first set


24


. Or, a skylight tube can be provided that has a slightly frusto-conical shape by using the second top element


28


TS, middle element


28


N, and bottom-most element


28


B of the first set


24


.





FIG. 3

shows a skylight dome fastener adaptor


40


that can be disposed in a hole

) to hold the dome


44


against the flashing


46


.




As shown in

FIG. 3

, the adaptor


40


includes a hollow hard plastic rigid body


54


that defines an outer surface


56


, and plural, preferably three, ribs


58


are formed on the outer surface


56


. The ribs


58


engage the hole


42


in the skylight dome


44


in an interference fit to impede rotation of the body


54


in the hole


42


when torque is applied to the fastener


52


.




In the preferred embodiment shown, each rib


58


includes an axially aligned outer edge


60


and opposed ramped sides


62


,


64


that extend from the edge


60


to the outer surface


56


of the body


54


. Thus, the ribs


58


have triangular cross-sections. As intended by the present invention, the ribs


58


are formed integrally with the body


54


.




In one preferred embodiment, the body


54


is formed with opposed chamfered ends


66


,


68


as shown. If desired, each rib


54

102


is formed with zip tie-like ratchet structure


110


that is configured to engage the ratchet tooth


97


of the support ring


90


and thereby hold the dress ring


82


onto the support ring


90


. Both the clip


108


and ratchet structure


110


are made integrally with the body of the zip clip


102


.




In a particularly preferred embodiment, the dress ring


82

, the lower end of the zip clip


102


is sandwiched between the abutment


112


and the vertical flange


86


of the dress ring


82


, to support the zip clip


102


. If desired, a small piece of felt


114


can be glued into the ratchet aperture


96


, with the zip clip


102


being biased against the felt


114


as indicated by the arrow


116

as shown. Furthermore, a rigid clip arm


126


is formed integrally with and extends perpendicularly away from the end


124


of the tie. In accordance with present principles, the clip arm


126


defines a channel


128


generally parallel to the body of the zip tie


120


and thus perpendicular to the clip arm


126


. It is to be appreciated in reference to

FIG. 5

that the channel


128


receives a threaded fastener


130


, such as a dry wall screw, with the fastener


130


self-tapping in the channel


128

With this structure, the zip tie


120


can be used to interconnect skylight assembly components such as a ceiling ring


132


and dress ring


134


holding a diffuser plate


136


with a portion of dry wall. More specifically, the zip tie


120


ratchetably engages the ceiling ring


132


and dress ring


134


in respective ratchet slots


138


,


140


, and then a structure such as a beam or ceiling or wall can be clamped between the arm


126


and ceiling ring


132


. Moreover, the fastener


130


can be manipulated to engage further wall or ceiling structure above the zip tie


120


. Completing the description of

FIG. 5

, the ceiling ring


132
