Description
LOUVERED ROOF ASSEMBLY
FIELD OF THE INVENTION
This invention relates to a louvered roof assembly and in particular to a specific design of louver to be used in a louvered roof assembly.
BACKGROUND OF THE INVENTION
There are numerous applications where it is desirable to have a roof, such as a canopy or awning, which can be removed to expose the area beneath to sunshine and be put back in place to protect the area from rain. However, given the rapid weather transitions in many locales, traditional canopies and awnings, which require some time to set up, are not always the best available option.
One alternative is to have a permanent or semi-permanent roof structure that can be opened and closed as desired. While retractable canvas awnings and the like are often used, another method is to assemble the roof using a series of louvers that pivot between an open and a closed position.
A problem with using a louvered roof is ensuring that the roof does not allow water to leak through when closed while retaining the louver action for opening and closing.
One attempt to address this problem is disclosed in U.S.
Patent No. 5,732,507 issued to Edwards. The louvers in Edwards have an up-turned lip along one edge and a down-turned lip on the other edge. When the louvers are closed, the up-turned lip on one louver overlaps the down-turned lip of an adjacent louver to produce a theoretically watertight seal. However, Edwards uses a rubber coating to create the seal between the lips, and the rubber can be subject to deterioration from sun and cold, reducing the effectiveness of the seal over time.
Also, while Edwards attempts to address one problem with louvered roof assemblies, that of making the louvers watertight when closed, a second problem remains. During heavy rains, water can accumulate on the roof and leak through the closed louvers, as the louvers do not provide any guttering effect to channel the water flow, either on the main structure or using the louvers themselves. Even worse, if the roof is flat, water can pool on the closed louvers, spilling into the roof-covered area when the louvers are opened.

DETAILED DESCRIPTION OF THE INVENTION
As shown in Figures 1 and 4, the invention consists of a roof assembly 10, comprised of a number of louvers 12 that can be moved between an open and a closed position (see Figure 3) and various intermediate positions by rotation about rods 24. At one end of the roof assembly 10 is a gutter 14 that runs along the length of roof assembly 10 below the louvers 12. The louvers 12 are connected to a mechanism 18 that allows the louvers to synchronously pivot between open and closed positions. The mechanism 18 can be controlled by any means suitable to the application of the roof assembly, ranging from a basic hand crank to a remote electronic switch used to operate an electromechanical actuator.
Each louver 12, as shown in Figure 2, has flanges 20 and 22 along respective opposite longitudinal edges and a channel 16 to allow water to flow along the length of the louver 12.
The louver 12 and channel 16 are preferably shaped so that the edge 28 of flange 22 defines a top edge of channel 16 when in the closed position. As a result, when water accumulates on the roof assembly 10, it flows along the louver channels 16 into the gutter 14 (see Figs. 1, 4 and 5), preventing water from leaking between the louvers 12.
Near an edge of each louver 12 opposite the channel-& 16 and on the underside is a notch 26 which prevents water from flowing around edge 28 and up the underside of louver 12.
Profile 29 on the underside of the louver 12 matches the curvature of rounded edge 28 forming a water-resistant seal when the two surfaces abut.
The opening 11 between the edge of the roof assembly 10 and the louvers 12 that allows water to flow into the gutter 14 is more clearly shown in Figure 4. The water flow into the gutter 14 through the opening 11 also helps prevent water from interfering with the opening/closing mechanism 18. Figure 5 shows the vertical positioning of gutter 14 relative to mechanism 18. A standard downspout (not shown) carries water in the gutter 14 to a drain (not shown).

DETAILED DESCRIPTION OF THE INVENTION
As shown in Figures 1 and 4, the invention consists of a roof assembly 10, comprised of a number of louvers 12 that can be moved between an open and a closed position (see Figure 3) and various intermediate positions by rotation about rods 24. At one end of the roof assembly 10 is a gutter 14 that runs along the length of roof assembly 10 below the louvers 12. The louvers 12 are connected to a mechanism 18 that allows the louvers to synchronously pivot between open and closed positions. The mechanism 18 can be controlled by any means suitable to the application of the roof assembly, ranging from a basic hand crank to a remote electronic switch used to operate an electromechanical actuator.
Each louver 12, as shown in Figure 2, has flanges 20 and 22 along respective opposite longitudinal edges and a channel 16 to allow water to flow along the length of the louver 12.
The louver 12 and channel 16 are preferably shaped so that the edge 28 of flange 22 defines a top edge of channel 16 when in the closed position. As a result, when water accumulates on the roof assembly 10, it flows along the louver channels 16 into the gutter 14 (see Figs. 1, 4 and 5), preventing water from leaking between the louvers 12.
Near an edge of each louver 12 opposite the channel-& 16 and on the underside is a notch 26 which prevents water from flowing around edge 28 and up the underside of louver 12.
Profile 29 on the underside of the louver 12 matches the curvature of rounded edge 28 forming a water-resistant seal when the two surfaces abut.
The opening 11 between the edge of the roof assembly 10 and the louvers 12 that allows water to flow into the gutter 14 is more clearly shown in Figure 4. The water flow into the gutter 14 through the opening 11 also helps prevent water from interfering with the opening/closing mechanism 18. Figure 5 shows the vertical positioning of gutter 14 relative to mechanism 18. A standard downspout (not shown) carries water in the gutter 14 to a drain (not shown).
Figure 6 shows a roof assembly 10 installed over a patio deck attached to a house. The roof assembly 10 is inclined so the water can flow along the louvers 12 via the channels 16 and into the gutter 14 (not shown). A hand crank 30 located on one of the roof assembly supports 32 controls the opening and closing of the louvers 12.
While the roof assembly 10 shown in Figure 6 is inclined such that water can flow freely along the louver channels 16, this inclined roof may not always be possible or desirable.
Therefore, the louvers 12 can alternatively have the channels 16 shaped as shown in Figure 7 so as to be inclined along the longitudinal axis to allow water to flow freely into the gutter 14 even if the louvers 12 of the roof assembly 10 are horizontally oriented (i.e. both ends of the louver are positioned at the same height). In the embodiment of Fig. 7 the surface of the channel 16 of each of the louvers 12 is sloped from a high point 17 at one end of the louver to a low point 19 at the other end. When the louver 12 is horizontal, water will run from the high point 17 to the low point 19.
An alternative embodiment of the louver 12 can be formed from two identical halves 38 as shown in Figures 8 and 9.
Each half 38 has a channel 16 with flange 22 defining the outer edge. Flange 22 allows water to flow off the top surface of the louver 12, and when in contact with a corresponding flange 22 of an adjacent louver, prevents water from flowing along the underside of the louver 12. The edge of each half 38 opposite the flange 22 has joint pieces 40 and 42 for attachment to like joint pieces 40 and 42 of a second louver half 38. The joined halves 38 are shown forming a complete louver 12 in Figure 9.
While the roof assembly 10 shown in Figure 6 is inclined such that water can flow freely along the louver channels 16, this inclined roof may not always be possible or desirable.
Therefore, the louvers 12 can alternatively have the channels 16 shaped as shown in Figure 7 so as to be inclined along the longitudinal axis to allow water to flow freely into the gutter 14 even if the louvers 12 of the roof assembly 10 are horizontally oriented (i.e. both ends of the louver are positioned at the same height). In the embodiment of Fig. 7 the surface of the channel 16 of each of the louvers 12 is sloped from a high point 17 at one end of the louver to a low point 19 at the other end. When the louver 12 is horizontal, water will run from the high point 17 to the low point 19.
An alternative embodiment of the louver 12 can be formed from two identical halves 38 as shown in Figures 8 and 9.
Each half 38 has a channel 16 with flange 22 defining the outer edge. Flange 22 allows water to flow off the top surface of the louver 12, and when in contact with a corresponding flange 22 of an adjacent louver, prevents water from flowing along the underside of the louver 12. The edge of each half 38 opposite the flange 22 has joint pieces 40 and 42 for attachment to like joint pieces 40 and 42 of a second louver half 38. The joined halves 38 are shown forming a complete louver 12 in Figure 9.
Accordingly, while this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications of the illustrative embodiments, as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to this description.
It is therefore contemplated that the appended claims will cover any such modifications or embodiments as fall within the scope of the invention.
