Definitions

  • the present invention relates generally to vertical louver type venetian blinds, and more particularly to a novel vertical louver venetian blind wherein the louvers have selectively contoured longitudinal marginal edges operative to create optical illusion effects.
  • louver type venetian blinds have been particularly well received in contemporary architectural constructions where relatively large expanses of window glass are employed. In such situations, the vertical louver blinds may be of substantial vertical height and, when closed, may extend along a considerable horizontal length of the corresponding wall and window area.
  • the relatively uninterrupted expanse of the vertical louver venetian blind enables broad variations in design and functional effect.
  • Conventional louvers or vanes employed in vertical louver blinds have substantially straight parallel longitudinal marginal edges and are adapted for movement between open blind positions drawn to one or opposite ends of a support track or channel, and closed blind positions wherein the vertical louvers are disposed in generally equal spaced relation along the track or channel.
  • the louvers are further adapted for selective rotation about their longitudinal axes when in closed blind positions to control the amount of light emitted into the corresponding room.
  • vertical louver type venetian blinds have a significant advantage over horizontal type venetian blinds in that the vertical louvers may more readily contribute to the overall design scheme of the corresponding room.
  • the vertical louvers may be made from vinyl or other suitable material colored to add an accent color to the room, or colored to blend with the main color of the room.
  • horizontal louvers may also be made of colored vinyl, they do not present the uninterrupted appearance of vertical louvers.
  • Vertical louvers may also be made from fabric material colored to provide an accent color or desired pattern which forms part of the rooms color scheme.
  • vinyl vertical louvers adapted to support fabric panels in combination vinyl/fabric louvers also lend themselves to a wide range of design schemes.
  • the present invention adds a further feature to the use of vertical louver venetian blinds to enhance interior design possibilities. More particularly, the present invention provides at least one contoured longitudinal marginal edge on selected ones of the vertical louvers so as to cause light controlled by the louver blind to create optical illusion or image effects which, in various embodiments, may take the form of generally three-­dimensional optical images or illusions.
  • one of the primary objects of the present invention is to provide a novel vertical louver venetian blind wherein selected ones of the vertical louvers have at least one nonrectilinear contoured longitudinal marginal edge.
  • a more particular object of the present invention is to provide a novel vertical louver type venetian blind having a plurality of vertical louvers supported for rotation about their longitudinal axes, and wherein selected ones of the louvers have at least one nonrectilinear contoured longitudinal marginal edge such that corresponding contoured edges of the louvers are operative to create an optical image or illusion effect.
  • Another object of the invention is to provide a vertical louver venetian blind wherein the inner longitudinal marginal edges on selected ones of the vertical louvers are contoured such that the contoured edges cooperate to create one or more visual images of geometric patterns and/or simulated inanimate characters when the louvers are in at least partially open positions such that light impinges inwardly facing side surfaces of the louvers and the blind is viewed such that the contour edges visually overlie the next adjacent rearward louvers.
  • a feature of the vertical louver venetian blind in accordance with the invention lies in the provision of louvers having corresponding nonrectilinear contoured longitudinal marginal edges which, in various embodiments, create a generally three-dimensional optical illusion effect when the louvers are in at least partially open positions and the blind is viewed from interiorly of the corresponding room at an angle of inclination to the planes of the louvers.
  • Another feature of at least one embodiment of the vertical louver venetian blind in accordance with the present invention lies in providing contoured edge louvers of contrasting colors so as to enhance the visual image created by the contour edges when light impinges the inwardly facing side surfaces of the louvers.
  • the venetian blind 10 includes a plurality of vertical louvers 12 which are supported at their upper ends from a generally horizontal support track or channel 14 through corresponding louver carriers (not shown) adapted to support the louvers for traverse along the support track between open blind and closed blind positions, and also enable selective rotation of the louvers about their vertical longitudinal axes.
  • the support track and louver carriers may take the form of any conventional known construction such as, for example, tracks and louver carriers commercially available from the LouverDrape Division of Home Fashions, Inc., Santa Monica, CA.
  • a draw cord 16 extends downwardly from the left-hand end of the support track 14 and is operatively coupled to the louver carriers to facilitate selective traverse of the louvers 12 between open blind positions adjacent one or the opposite ends of the guide track 14, and closed blind positions wherein the louvers are spaced generally equally along the length of the support track.
  • a separate control in the form of a beaded chain may hang downwardly with the draw cord 18 and enables selective rotation of the louvers about their vertical longitudinal axes in a known manner when the louvers are in closed blind positions so as to control the amount of light emitted into the corresponding room from a window covered by the vertical louver venetian blind.
  • louver operating mechanism adapted to enable opening and closing of the blind through a draw cord, and facilitate selective rotation of the louvers about their longitudinal axes by a beaded chain or the like between open and closed louver positions is disclosed in U.S. Patent No. 4,834,162 which is incorporated herein by reference.
  • the vertical louvers 12 are preferably made of a relatively rigid material, such as rigid vinyl or other suitable material, so that the louvers maintain a generally fixed transverse cross-sectional configuration when suspended from the guide track 14.
  • the louvers 12 may be made of a suitable fabric material or a combination vinyl and fabric. In all cases, it is desirable that the louvers hang vertically and in parallel relation to each other.
  • the lower ends of the louvers may be interconnected by spacer chains or the like to maintain stability and parallelism of the vertical louvers without inhibiting rotation about their longitudinal axes.
  • the vertical louvers are generally planar.
  • the louvers may be formed as non-planar louvers having generally S-shaped, C-shaped or other non-planar transverse cross-sectional configurations.
  • each louvers 12 has substantially greater transverse width than thickness, and each louver has longitudinal marginal edges as indicated at 18a and 18b in FIG. 2.
  • at least one of the longitudinal marginal edges 18a and 18b of selected ones of the louvers 12 has a nonrectilinear contour configuration.
  • each louver 12 has both of its longitudinal marginal edges 18a and 18b contoured in symmetrical nonrectilinear configurations, alternatively termed curvilinear contour configurations, taking generally the form of sine waves.
  • only one of the longitudinal marginal edges, preferably the inwardly facing edges 18a, of the vanes 12 may be formed with a sine wave contour configuration, while the opposite outwardly facing longitudinal marginal edges 18b of the vanes may be formed as straight edges or as curvilinear contour edges different than the contour of the corresponding inner edges 18a.
  • the adjacent vertical louvers 12 of the venetian blind 10 are longitudinally or vertically offset relative to each other so that, except for the end louvers, a convex curvature portion 18c of each louver contour edge is at a horizontal level corresponding to a concave curvature portion 18d of the next adjacent louver on either side of the louver under consideration.
  • a generally three-­dimensional optical illusion effect is created by light emitted through the closed venetian blind when the louvers are in fully open or partially open louver positions so that light impinges the inwardly facing side surfaces of the louvers and the venetian blind is viewed from internally of the corresponding room at an angle of inclination, such as between about 45°-90°, to the planes of the louvers so that the inwardly facing contoured longitudinal edge of each louver is in the foreground of and visually overlies the side surface of the adjacent rearward louver.
  • such an angle of inclination may be established by rotating the louvers 12 relative to their fully open positions normal to the support track so that light impinges the inwardly facing sides of the louvers and the inward longitudinal edge of each louver overlies the next adjacent rearward louver side surface, or by viewing the partially open louvers at an angle of inclination which achieves the same result.
  • the optical illusion effect created by the contour edge vertical louvers 12 may be altered by rotating the louvers about their longitudinal axes to vary the amount of light emitted between the vertical louvers and impinging common planar sides of the louvers.
  • the louvers 12 may be given contrasting colors so that each louver is of a different color than the next adjacent louvers on either side of the louver under consideration.
  • each odd numbered louver counting from the left-hand edge of blind 10
  • may be of a relatively light color such as white or other light color.
  • Each even numbered louver may be of a relatively dark color such as brown or other contrasting color. In this manner, the visual image created by the contoured edge louvers and light impinging the inwardly facing side surfaces of the louvers is significantly enhanced.
  • the visual image generally created by natural light passing through the partially open louvers can also be achieved by artificial light impinging inwardly facing side surfaces of the louvers from internally of the corresponding room, particularly when the louvers are in closed or substantially closed positions.
  • This feature of alternate contrasting color louvers can also be applied to the following described embodiments of the invention.
  • FIG. 4 is a fragmentary perspective view of a vertical louver venetian blind, indicated generally at 20, which includes a plurality of generally planar vertical louvers 22 constructed in accordance with another embodiment of the present invention.
  • the louvers 72 are supported from their upper ends through a support track and associated louver carriers (not shown) in similar fashion to the louvers 12 so as to enable traverse of the louvers between open and closed blind positions, and rotation of the louvers about their longitudinal axes between closed louver and open louver positions to control the amount of light emitted through the venetian blind.
  • Each of the louvers 22 has longitudinal marginal edges 22a and 22b at least one of which, preferably the inwardly facing longitudinal edge 22a, is formed with a nonrectilinear contour configuration, alternatively termed a curvilinear contour configuration.
  • the inwardly facing longitudinal marginal edges 22a of the vertical louvers have irregular longitudinal contour curvatures such that the inner contoured edges 22a of each pair of adjacent vertical louvers are different.
  • the outer longitudinal edge 22b of each louver 22 may be formed as a straight edge parallel to the longitudinal axis of the louver, or may be formed as an irregular contour curvature similar to the corresponding inwardly facing longitudinal edge.
  • a generally three-dimensional optical illusion effect of random abstract images is created across the horizontal width of the venetian blind when the louvers are in fully open or partially open positions so that light emitted through the blind impinges the inwardly facing side surfaces of the louvers and the blind is viewed from internally of the corresponding room at an angle of inclination, such as between about 45°-90°, relative to the planes of the louvers with the inner edge of each louver visually overlying the side surface of the next adjacent rearward louver.
  • the optical illusion effect created by the contoured louvers 22 may be varied by rotating the louvers about their longitudinal axes so as to selectively control the amount of light emitted through the venetian blind 20 and impinging corresponding inwardly facing planar sides of the louvers.
  • FIG. 5 illustrates another embodiment of a vertical louver type venetian blind, indicated generally at 30, employing contoured edge vertical louvers in accordance with the present invention.
  • the venetian blind 30 includes a plurality of vertical louvers 32 which are supported at their upper ends from a support track and associated louver carriers (not shown) in similar fashion to the louvers 12. Selected ones of the vertical louvers 32, and preferably all of them, have at least their inwardly facing longitudinal marginal edges 32a formed in nonrectilinear contour configurations.
  • the inner longitudinal marginal edges 32a are formed as generally irregular curvilinear curvatures giving the appearance of somewhat jagged longitudinal edges.
  • the opposite outwardly facing longitudinal marginal edges of the louvers 32 may be formed as straight edges or as nonrectilinear contour configurations similar to the inner edges 32a.
  • the contour edge vertical louvers 32 are operative to create a generally three-dimensional abstract-like optical illusion effect as light is selectively emitted through the contoured vertical louvers and impinges upon common planar inwardly facing side surfaces of the louvers, and when the blind is viewed from internally of the corresponding room at an inclined angle of between approximately 45° and 90° to the planes of the louvers so that the inner edge of each louver visually overlies the side surface of the next adjacent rearward louver.
  • FIG. 6 is a fragmentary perspective view of another embodiment of a vertical louver type venetian blind, indicated generally at 40, which employs contour edge vertical louvers 42 supported at their upper ends from a support track by corresponding louver carriers (not shown) enabling traverse of the louvers between open and closed blind conditions, and enabling selective rotation of the louvers about their longitudinal axes when in closed blind positions so as to control the amount of light emitted through the venetian blind.
  • the vertical louvers 42 have at least one longitudinal marginal edge, preferably their inwardly facing longitudinal edges 42a, formed in a contour configuration taking the form of a generally scalloped contour.
  • the contoured longitudinal edges 42a of selected ones of the louvers 42 may take the form of negative or concave scallops, such as formed on the louvers indicated at 42′, or may take the form of positive or convex scallops such as formed on the louvers indicated at 42 ⁇ .
  • the negative and positive scalloped edge louvers may be selectively combined and oriented to obtain different optical illusion effects across the width of the venetian blind.
  • the left-most and third-from-left vertical louvers 42′ have negative or concave scalloped contour inwardly facing longitudinal edges, while the intermediate vertical louver 42 ⁇ has a positive or convex scalloped contour inwardly facing longitudinal edge which is oriented such that its convex scallops are horizontally aligned with concave scallops on the next adjacent louvers.
  • the louvers to the right of the second louver 42′ may comprise a series of positive or convex scalloped edge contour louvers 42 ⁇ which are vertically or longitudinally offset relative to each other by a distance equal to approximately one-half the length of a chord connecting the ends of an arcuate scallop.
  • the vertical louvers 42′ and 42 ⁇ may have their outwardly facing longitudinal marginal edges formed as curvilinear or scalloped contour configurations similar to their corresponding inwardly facing longitudinal edges, or may be formed as straight edges parallel to the longitudinal axes of the associated louvers.
  • By alternating the vertical louvers 42′ and 42 ⁇ generally three-dimensional spherical-like optical illusions or images are created as the louvers are viewed from internally of the corresponding room and light is emitted through the venetian blind so as to impinge corresponding inwardly facing planar sides of the louvers.
  • FIG. 7 illustrates a fragmentary portion of a vertical louver venetian blind, indicated generally at 50, employing contour edge vertical louvers 52 in accordance with another embodiment of the present invention.
  • the louvers 52 are supported at their upper ends from a support track by associated louver carriers (not shown) so as to enable selective traverse of the louvers between open and closed blind positions, and also enable rotation of the louvers about their longitudinal axes between open louver and closed louver positions to control light emitted through the venetian blind.
  • each of the louvers 52 has an inwardly facing longitudinal marginal edge 52a which is defined as having a nonrectilinear contour configuration even though the longitudinal edge is a combination of straight edge portions interrupted by patterns of inwardly directed recesses.

  • the recesses 52c in the various vertical louvers 52 may be formed in different patterns and at various angles of inclination to the corresponding inwardly facing longitudinal edges of the louvers so that the longitudinal edges of adjacent louvers 52 have different contour configurations.
  • the thus contoured inner longitudinal edges of the louvers 52 create an abstract-­like optical illusion effect when the louvers are viewed from internally of the corresponding room, preferably at an inclined angle to the planes of the louvers, so that the inner edge of each louver visually overlies the side surface of the next adjacent rearward louver and when the louvers are selectively rotated about their longitudinal axes so that light emitted through the venetian blind 50 impinges inwardly facing planar side surfaces of the louvers.
