Description

[0001] The invention broadly relates to window coverings, more specifically to a telescoping window covering, and even more particularly to a mountable telescoping 5 window covering having expandable louvers, a concealed tilt bar and an expansion limiter.

BACKGROUND [0002] Louvered window shutters have been used for many years to control room lighting, privacy, security, environmental protection and aesthetics. Conventional 10 window shutters suffer from a number of drawbacks. For example, windows are manufactured in a variety of sizes and shapes. As such, it is difficult to construct standard shutters that will fill the opening formed by each window. Thus, some customization must occur with each shutter in order for it to provide its desired characteristics, e.g., privacy and lighting level. Shutters are custom built to size, or may 15 be formed by assembling multiple portions that collectively fill a window opening.

Moreover, a variety of other window covering types are also available, e.g., curtains, shades, blinds, etc. All of the foregoing window coverings suffer from similar drawbacks as window shutters.

[0003] As can be derived from the variety of devices and methods directed at providing window coverings, many means have been contemplated to accomplish the desired end, i.e., convenient, cost effective and configurable arrangements. Heretofore, tradeoffs between flexibility in configuration and cost were required. Thus, there is a long-felt need for a window covering that can be modified to fit within and cover any window opening shape and/or size.

SUMMARY [0004] The presently disclosed apparatus broadly comprises a window covering having an interior face and an exterior face including an outer frame portion, an inner frame portion, at least two outer louvers, at least two inner louvers and a tilt bar. The outer frame portion includes an upper horizontal frame extrusion, a lower horizontal 30 frame extrusion, and a vertical frame extrusion connecting the upper and lower horizontal frame extrusions of the outer frame portion. The inner frame portion includes

01 19 an upper horizontal frame extrusion, a lower horizontal frame extrusion, and a vertical frame extrusion connecting the upper and lower horizontal frame extrusions of the inner frame portion. The upper and lower horizontal frame extrusions of the inner frame portion are nestedly and slidably arranged within the upper and lower horizontal frame 5 extrusions of the outer frame portion. The at least two outer louvers each form a cavity therein, while the at least two inner louvers are each nestedly and slidably arranged within the cavity of one of the at least two outer louvers. The tilt bar is pivotably connected to the at least two outer louvers or to the at least two inner louvers, and arranged adjacent the exterior face of the window covering.

[0005] It is a general object of the present apparatus to provide a window covering that is aesthetically pleasing while solving drawbacks of known coverings, e.g., flexibility of size/shape.

[0006] These and other objects and advantages of the present invention will be readily appreciable from the following description of preferred embodiments of the 15 invention and from the accompanying drawings and claims.

Figure 4 shows a front perspective view of an embodiment of a present window covering in an expanded arrangement 25 shown with louvers in a closed arrangement and louvers in an open arrangement. Figure shows an exploded view of an embodiment of a present window covering. The following is best understood in view of Figures 1-5.

[0013] Window covering 50 includes interior face 52 and exterior face 54. As described above, interior face 52 is the face of window covering 50 viewable from 30 inside a space within which window covering 50 is installed, e.g., inside of a living room, while exterior face 54 is the face of window covering 50 not viewable from inside that space, e.g., the face of window covering 50 adjacent window 56. Window

01 19 covering 50 comprises outer frame portion 58, inner frame portion 60, at least two outer louvers 62, at least two inner louvers 64 and tilt bar 66. Outer frame portion 58 comprises upper horizontal frame extrusion 68, lower horizontal frame extrusion 70, and vertical frame extrusion 72 connecting upper and lower horizontal frame extrusions 5 68 and 70, respectively, of outer frame portion 58. Inner frame portion 60 comprises upper horizontal frame extrusion 74, lower horizontal frame extrusion 76, and vertical frame extrusion 78 connecting upper and lower horizontal frame extrusions 74 and 76, respectively, of inner frame portion 60. Upper and lower horizontal frame extrusions 74 and 76, respectively, of inner frame portion 60 are nestedly and slidably arranged 10 within upper and lower horizontal frame extrusions 68 and 70, respectively, of outer frame portion 58. Each outer louver 62 forms cavity 80 therein. Each inner louver 64 is nestedly and slidably arranged within a complementary cavity 80 of one of outer louvers 62. It should be appreciated that a complementary cavity within an outer louver is a cavity that is generally aligned with an inner louver such that the combination of 15 the inner louver within the outer louver forms a substantially horizontal louver 82. Tilt bar 66 is pivotably connected to outer louvers 62 or to inner louvers 64, and is arranged adjacent exterior face 54 of window covering 50. It should be further appreciated that “adjacent”, as used in the present context, is intended to mean that tilt bar 66 is next to or near exterior face 54 and not next to or near interior face 52. It should be further appreciated that outer louvers 62 and inner louvers 64 may include features that permit the direct connection of tilt bar 66 thereto; however, a cap positioned at the distal ends of each outer and inner louver 62 and 64, respectively, may also be included thereby permitting connection between tilt bar 66 and outer and inner louver 62 and 64, respectively.

[0014] It should be appreciated that the foregoing arrangement of tilt bar 66 relative to outer and inner louvers 62 and 64, respectively, and further relative to interior and exterior faces 52 and 54, respectively, generally conceals tilt bar 66 from view when window covering 50 is positioned in front of window 56. Thus, window covering 50 produces a desirable, clean aesthetic appearance where louvers 82 are 30 unobstructed by tilt bar 68. Such an arrangement produces a clean appearance that is not possible with known window coverings, i.e., tilt bar 66 is not generally visible.

76, respectively, of inner frame portion 60 comprises inner frame louver block 86. At least a portion of inner frame louver block 86 is nestedly arranged within outer frame louver block 84. (See, Figure 7). Outer and inner frame louver blocks 84 and 86, respectively, provide a convenient means to limit rotation of louvers 82 and further provide a means to ensure proper orientation of components during assembly, e.g., alignment of lower horizontal frame extrusion 70 relative to vertical frame extrusion 72.

[0017] In some embodiments, first end 88 of each of outer louvers 62 is pivotably secured to vertical frame extrusion 72 of outer frame portion 58 and first end 90 of each 25 of inner louvers 64 is pivotably secured to vertical frame extrusion 78 of inner frame portion 60.

Moreover, the arrangement of the present window covering permits a single assembly to be used on either side of a window or other type of opening, e.g., a doorway, without modification of the window covering. Thus, regardless of the side of an opening that is desired to be covered, the same window covering can be used. This arrangement simplifies manufacturing processes, reduces overall costs and provides for 10 a convenient installation process. The present arrangement provides an expandable and contractible window covering that may be conformed to fit within a variety of opening sizes. The present window covering can be linearly expanded and contracted to fill an opening. However, it should be appreciated that the foregoing arrangement may also include arcuate members thereby permitting a curved expansion and contraction of the 15 covering.

[0027] Thus, it is seen that the objects of the present invention are efficiently obtained, although modifications and changes to the invention should be readily apparent to those having ordinary skill in the art, which modifications are intended to be within the spirit and scope of the invention as claimed. It also is understood that the foregoing description is illustrative of the present invention and should not be considered as limiting. Therefore, other embodiments of the present invention are possible without departing from the spirit and scope of the present invention.
