The present invention is broadly directed to adjustable louvered roof structures and more particularly to a novel improved adjustable louvered roof system with an improved bearing system, the roof system being easier to maintain.
Conventional louvered roof assemblies include parallel louvers which are rotated between an open and closed position, as desired. However, many of these systems have a large amount of friction which increases the wear and tear upon the rotatable surfaces but also upon the power equipment as they cause additional drag to the power equipment and require additional power for rotation of the louvers. Therefore, there exists a need to reduce the friction upon the rotatable surfaces.
Some louvered roof assemblies are installed in an outdoor environment where they provide shade and shelter from the underlying area. These roof assemblies also provide shade from the sun. Additionally, these roof assemblies are used at night where lighting is needed to help see in the dark area below the louvers. In addition to task lighting, ambience lighting may be desired to help illuminate the area. However, installing electrical cords and hanging light fixtures around or from the louvers may create an electrical hazard, impact the rotation of the louvers or cause them to fail under the weight of the hanging light fixtures. Therefore, there exists a need to provide an improved illumination system for use with the louvered roof assembly.
Some louvered roof assemblies are installed in an outdoor environment where surrounding trees, bushes and plants may deposit organic debris upon the louvered roof assembly. Some of this debris may become lodged into the rotational surfaces of the louvers which can restrict flow of water or cause water to buildup, increasing the load of the roof assembly and potentially causing the roof to fall or cave-in. Cleaning or removal of any lodged debris may require someone with sufficient expertise and again, based on their availability may still allow a roof to fall or cave-in. In some environments, built-up water may become frozen and expand, causing various mechanical or structural components to break or fail. Therefore, there exists a need to provide for an improved louvered roof assembly system with a way to prevent debris from clogging various components and allowing water to properly drain-off.
Some louvered roof assemblies have louvers which have limited structural support and are unable to satisfactorily span the roof structure. Not every roof assembly is the same size. Some areas are smaller, some are larger. However, louvers with insufficient structural support may not be used in these larger areas or if used, may fail or break. The lack of structural support may also allow the louvers to fail or break over time based upon the ambient condition. Some conditions which can increase the risk of failure include windy, snowy or rainy environments. Therefore, there exists a need to provide improved structural support for the louvers for use with an improved louvered roof assembly which is safer and stronger.
Many louvered roof assemblies allow for adjustment of the louvers between an opened or closed position with a motor operated by a battery or a person. Some include interconnecting or interlocking structure which allows the louvers to rotate between the open and closed position simultaneously. However, many of these louvers are not properly adjusted for full open or full closed positions. In addition, many do not sufficiently close to seal out harsh environmental elements like the snow, rain or wind or prevent the louvers from freezing or slamming shut and potentially damaging the louvers or roof assembly. Therefore, there exists a need to provide for an improved louvered roof assembly with a better sealing structure to protect the assembly from the harsh environmental elements.
Accordingly, there is a need for an improved louvered assembly which reduces friction, strengthen the louver while providing improved lighting, reducing debris and improving drainage, addressing at least a portion of the aforementioned shortcomings.
The present invention is a mounted roof system with a plurality of louvers which includes interconnecting structure to allow the louvers to open and close in a synchronized manner as desired. The mounted roof system can be mounted to a wall, an eave or may be free standing over an area. The interlocking louvers having an improved interlocking structure and improved structural design can span a larger frame structure, the frame structure further utilizing illumination mounting devices and drainage enabling structures like protective screens which provides water resistance, wind resistance and debris resistance over existing roof systems.

As illustrated in
The improved louvered panel assembly 20 includes a plurality of louvers 22 in rotatable communication, mounted within the frame 4. Each louver 22 includes the substantially planar surface 46 and a convex surface 45 joined together at leading edge 51 and a trailing edge 61. In the illustrated embodiment, both the leading and trailing edge 51, 61 have a curved shape. In general, the leading edge 51 and trailing edge 61 present a pair of channels. The first channel 23 is associated with the leading edge 51 and a second channel 24 is associated with the trailing edge 61. A plurality of interiorly spaced uprights 44 extend between the lower planar surface 46 and upper convex surface 45, each spaced upright 44 presenting a longitudinally extending plane. The rotational axis 26 extends longitudinally and centrally through an aperture in the receiver 34 of the louver 22 that receives a first bearing surface 37 and a second bearing surface (not shown).
In the illustrated embodiment, the first bearing surface 37 and second bearing surface (not shown) are functionally equivalent with both having an outer rolling surface operably connected at a central region to a cylindrical projection configured for receipt within a central receiver 34 associated with each louver 22
In operation, each louver 22 rotates about a rotational axis 26 extending longitudinally through the central receiver 34 from a first end 25a to a second end 25b. The open parabolic channel 56 presents an arcuate opening 57 which presents the pivot for pivoted operation of the louver 22 as it moves from the closed to open positions. A pivot axis generally extends along the open parabolic channel 56 during rotation of the louver 22 about the rotational axis 26 through the arcuate opening 57. In the depicted embodiments of

According to the embodiment of the louvered panel assembly 20 illustrated in
A roller 37 is operably connected to the cylindrical bearing 35 for maintaining the position of the louver 22 during rotation from the open to the closed position. The roller 37 is generally received within the track 48, the roller 37 extending outwardly through the track 48 at one of the plural slots 49. Generally, each slot 49 corresponds to each louver 22, the slots 49 being spaced apart a distance corresponding to the width of each louver 22 and generally aligned along the rotational axis 26 extending centrally from the roller 37 through the central receiver 34. Generally, the slots 49 are spaced along the track 48 as desired for longitudinal spacing of the louvers and have a dimension less the diameter of the roller 37 to help contain the roller 37 within the track 48. The slots 49 allow for controlled rotation of the roller 37 within the slot 49 thereby maintaining the roller 37 in alignment at the desired position along the track 48.
The cylindrical bearing 35 centrally receives a spacer 33 associated with the roller 37 and extending from the roller 37 for receipt by the cylindrical bearing 35. Generally, a spacer 33 allows for proper lateral positioning of the louver within the installed frame for alignment during operation of the panel assembly 20 while maintaining each louver 22 in rotational alignment with the rotational axis 26. Generally, the tracks 48 are secured to the frame 4 in pairs and are secured in a direction normal to the louvers 22 at the first and second ends 25a, 25b. In the illustrated embodiment of the panel assembly 20, one or both tracks 48 are associated with opposite frame 4 members, each track 48 receiving a plurality of the rollers 37.

The illustrated embodiment of the illumination strip 74 may be an incandescent filament style or LED style, particularly an LED array arranged in a strip 74. However, other types of illumination may be utilized including ropes, strips and tapes, some may have the same color, some may include a variety of colors, some may be low power, other may be higher power, some may be dimmable, some may be wireless, some may be battery powered. In one embodiment, the illumination is provided by a water-proof LED strip, based on the standards of IP65 or IP67 and of a particular color, like blue. Alternatively, the track 48 with various elongated channels may also be used to secure additional illumination strips 74 along a lower portion of the track 48.
A control arm 30 is used for moving a plurality of louvers 22, also referred to as a louver assembly 20 or panel, between the open and closed positions. One embodiment of the control arm 30, illustrated in

An alternative louver assembly 140 is illustrated in
The alternative louver assembly 140 presents a roof structure with a seal provided between adjacent alternative louvers 122 which presents a partially sealed barrier to ambient conditions for use as the top of an enclosure or a three (3) season room. The louvers 22 and alternative louvers 122 present a substantially planar bottom surface when in the closed position.
The alternative control arm 130 illustrated in
As further illustrated in
A chord is presented by the louver 22 which corresponds to the distance from the curved leading edge 51 to the curved trailing edge 61. The chord is generally configured to conform to the desired aerodynamic effect of the ambient air extending along the louver surface 22. In one embodiment, the curved trailing edge 61 is designed to maintain a desired chord distribution to minimize elliptic loading. Generally, the chord describes the curvature effect of the louver 22 from the leading edge 51 to the trailing edge 61. The louver 22 has a convex upper surface 45 and a substantially planer lower surface 46, a plurality of supporting members illustrated as vertical uprights 44 extending between the upper surface 45 and lower surface 46. In the depicted embodiment, the vertical uprights 44 are generally spaced equally throughout the louver, generally located at the 25 and 75 percent chord positions and presenting a plane of support.
A central receiver 34 is generally located near the middle chord position and includes an upper section 54 and a lower section 64. The upper section 54 generally corresponds to the convex area above the chord and the rotational axis 26 and the lower section 64 generally corresponds to the more planar area below the chord and the rotational axis 26. The upper and lower sections 54, 64 come together at the central receiver 34.
The central receiver 34 is generally adapted for receipt of a cylindrical bearing 35 and upon receipt, the friction between the central receiver 34 and the spacer 33 rotates with less friction during rotation of the louver 22. Generally, the cylindrical bearing 35 assists in reducing rotational friction as the louver 22 rotates from the open to the closed position.
An embodiment of the overlying structure 50 is depicted in
The depicted embodiment of the trailing projection 62 illustrates a substantially vertical projection 63 with a forwardly extending trailing arm 65 which presents an upper channel 66. The upper channel 66 is adapted for removable receipt of the resilient member 36 presenting a weather resistant seal. Generally, the leading projection 52 and trailing projection 62 are adapted for interconnection in an overlying orientation with the leading projection 52 overlying the trailing projection 62 and with the assistance of a resilient membrane 36 received within the upper channel 66, presenting a weather resistant barrier while the louvers 22 are in the closed position. In the depicted embodiment, the resilient membrane 36 may be selectively removed from the upper channel 66 as desired.
As further illustrated in
In one embodiment while the louvered roof assembly 20 is in the closed position a visually appealing surface is provided from the underlying area 2 from which the closed louvers 22 may depict a tongue and groove surface, which along with the gutter 70, may be fashioned to appear like various types of trim molding, like crown, thereby enhancing the visual appeal and aesthetics of the area 2 surrounded by the improved louvered roof assembly 20.
Generally, the flap structure 250 will rotate up when the louvers 22, 122 are closed and will rotate down when the louvers 22, 122 are open, providing protection against bugs in the summer months and to at least partially seal when the weather is cold. The rotatable joint is generally comprised of a socket 148a and a ball 250a. In operation, the flap structure 250 is positioned in the winter position by turning off power to the operator 80 and rotating the alternative louvers 122 closed and then rotating the flap structure 250 with the alternative membrane 236 under the alternative louvers 122.
The alternative track 148 generally includes an upper section presenting the socket 148a and a depending leg 148b having a confirming shape for receipt by the triangular channel 180. The depending leg 148b is generally configured for supporting the flap structure 250 as it rotates between an upper, generally vertical position and a lower, generally horizontal position. The flap structure 250 generally presents an arcuate surface on one side and a planar surface on the opposite side joined by an alternative upper channel 166 and a rotatable support 250a extending rearwardly for receipt by the socket 148a during rotation of the flap structure 250. The alternative upper channel 166 is generally adapted for receipt of the second alternative membrane 236. In general, the sealing membrane 36, alternative sealing membrane 160 and second alternative membrane 236 at least partially seal the louvers 22, 122 to selectively limit ambient conditions (like wind or rain), debris (like leaves, limbs or pollen) or animals (like bugs) from the underlying area.
It is to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of the parts described and shown.
