Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to vertical partition-type venetian blinds, and more particularly, the invention relates to venetian blinds of the vertical partition type, and in particular to louvers in which selective longitudinal contours create an optical illusion effect. ) relates to a new vertical partition board blind.

(Prior Art and Problems to be Solved by the Invention) The advent of vertical partition type blinds has brought new ideas to interior design in both commercial and residential facilities. Vertical partition-shaped blinds are particularly well-suited to modern architecture that uses relatively large expanses of glazing. In such cases, vertical partition blinds are
It is of considerable height and, when closed, extends over a considerable horizontal length of the corresponding wall and window area. The relatively uninterrupted extension of the vertical partition board makes it possible to realize a wide variety of design and functional effects. Traditional partitions used in vertical partition boards have substantially straight and parallel longitudinal edges;
between an open position of the slat in which the slats are drawn to one or both ends of the support track or channel and a closed position of the slat in which the vertical partitions are approximately equidistantly spaced along the track or channel; It is now possible to move. The partition is further adapted to be selectively rotated about its longitudinal axis in the slat closed position to adjust the amount of light admitted into the corresponding room.

In many installations, vertical partition slats have a significant advantage over horizontal slats in that the vertical partition contributes more easily to the overall design scheme of the corresponding room. For example, a vertical partition can be made from vinyl or other suitable material that is colored to add an accent color to the room or to match the main color of the room. Horizontal partitions can also be made of colored vinyl, but it does not provide the continuous appearance of vertical partitions. Vertical partitions can also be made from textile materials that are colored to provide accent colors or desired patterns that form part of the main plan of the room. Furthermore, vinyl vertical partitions adapted to support textile panels in combination with vinyl/textile partitions are also suitable for a wide variety of design schemes.

SUMMARY OF THE INVENTION The present invention adds features to the application of vertical partition blinds that enhance interior design possibilities. To be more specific,
The present invention provides at least one of the vertical partitions for controlling the light to create an optical illusion or image effect that in various embodiments takes the form of a substantially three-dimensional optical image or illusion. provide a longitudinal edge contour.

Accordingly, one of the main objects of the present invention is to provide a new vertical partition board in which selected ones of the vertical partitions have at least one non-straight longitudinal edge.

A particular object of the invention is to have a plurality of vertical partitions supported for rotation about a longitudinal axis, wherein selected ones of the partitions have a corresponding contoured edge that is an optical image or It is an object of the present invention to provide a novel vertical partition template having at least one non-linear longitudinal edge contoured to create an illusion effect.

Another object of the invention is that the partition is in an at least partially open position, such that light is incident on the inwardly facing side of the partition and the contoured edge is visually visible to the next adjacent rear partition. of the vertical partitions such that the contour edges cooperate to create one or more visible images of one or more geometric patterns and/or simulated inanimate symbols when viewed overlappingly. The purpose of the present invention is to provide vertical partition panels whose inner longitudinal edges of selected ones are contoured.

A feature of the vertical partition board blind of the present invention is that, in various embodiments, the partition is in an at least partially open position, and the iron board blind is extended from the inside of the corresponding room at an angle of inclination to the plane of the partition. The provision of a partition with a corresponding non-linear longitudinal profile edge produces an approximately: three-dimensional optical illusion effect when observed.

Another feature of at least one embodiment of the vertical partition screen of the present invention is that the contour edges may be colored in contrasting colors to intensify the visible image produced by the contour edges when light is incident on the inwardly facing side of the partition. It is to provide a contour edge partition.

Other objects and features of the invention will become apparent from the following detailed description when taken in conjunction with the male drawings. In the drawings, like reference numbers refer to like elements.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, and in particular to FIGS. 1-3, there is shown a portion 10 of a vertical partition template constructed in accordance with one embodiment of the present invention. The sash 10 has a plurality of vertical partitions 12 such that the partitions 12 are supported at their upper ends from generally horizontal support tracks or channels 14 passing through corresponding partition support devices (not shown). , the partition support device (not shown) supports the partition for movement along the support track between an open board stub position and a closed board stub position, and selects the partition about its vertical longitudinal axis. It is designed to allow rotation. Support tracks and partition support devices are available, for example, from Louver Drape Division (L.

uberDrape l1livision of
llome l1ashios, Inc.)
It can take the form of common known constructions, such as track and partition support devices commercially available from . A pull line 16 extends downwardly from the left end of the support track 14 and is coupled to the partition support device to connect the partition to an open board sill location adjacent one or the other end of the guide track 14 and substantially along the entire length of the support track. Selective movement of the partition 12 between the closing plate blind positions which are located at equal intervals is facilitated. Further control means in the form of a beaded chain (1 not shown) may be suspended with the draw line 18, which causes the partition to move around its vertical longitudinal axis in a known manner when the partition is in the closing plate position. The aspect can be selectively rotated to control the amount of light that enters the corresponding room through the window covered by the vertical slat. Example of a partition operating mechanism that allows the opening and closing of a board blind through a bow rope and facilitates selective rotation of the partition about a longitudinal axis between an open partition position and a closed partition position by a beaded chain. is disclosed in U.S. Pat. No. 4,834,162, which is incorporated herein by reference.

The vertical partition 12 preferably has a guide track 14
It is preferably made of a suitably rigid material, such as hard vinyl, so that it maintains a generally fixed cross-sectional shape when suspended from a wall. The partition 12 can also be made of a suitable textile material or a combination of vinyl and textile. In all cases it is desirable for the partitions to hang vertically and parallel to each other. In order to maintain the stability and parallelism of the vertical partition without interfering with its rotation about its longitudinal axis, the lower ends of the partition can be tied together by spacer chains or the like, if desired. In various embodiments described below, the vertical partitions are generally flat, but the partitions may also be formed as uneven partitions having an S-shape, a C-shape, or other non-flat cross-sectional shapes.

The width of each partition 12 is substantially greater than the thickness;
Each partition has longitudinal edges designated 18a and 18b in FIG. According to an important feature of the invention, longitudinal edges + of selected ones of the partitions 12
At least one of 8a and 18b has a non-linear profile shape. In the embodiment shown in FIGS. 1-3, both longitudinal edges 18a and 18b of each partition 12 have a symmetrical non-linear (in other words curved) contour, approximately sinusoidal. It is in the shape of a wave. If desired, only one of the longitudinal edges of the partition 12 (preferably the inwardly facing edge 18a) has a sinusoidal contour, while the opposite, outwardly facing edge of the partition The vertical edge 18b is a straight edge or a corresponding inner edge 1
Adjacent vertical partitions 12 of the board blinds 10, which may be formed as curved contour edges different from the contour of 8a, in the longitudinal direction
That is, they are mutually offset in the vertical direction and, with the exception of the end partitions, the convex curves 18c of each partition contour edge are at a horizontal level corresponding to the curves 18d of the adjacent partitions on either side of the partition. The longitudinal edges of the partition 12 have such a contour, so that when the partition is in a fully or partially open partition position and light is incident on the inwardly facing side of the partition, the wooden blinds can be used as partitions. viewed from inside the corresponding room at an angle of inclination of, for example, between approximately 45° and 90° to the plane of When in front of and visually overlapping a side surface, the light passing through the closed sash creates an almost three-dimensional optical illusion effect. Depending on the width of the partitions, the partitions 12 may be rotated relative to their fully open position perpendicular to the support tracks so that light is incident on the inwardly facing sides of the partitions and the inner longitudinal edges of each partition are adjacent to each other. This angle of inclination can be created by overlapping the sides of the rear partition, or by observing a partially open partition with an angle of inclination that achieves the same result. Rotating the partition about its longitudinal axis changes the optical illusion effect created by the contoured vertical partition 12 by varying the amount of light emitted between the vertical partitions and incident on the common plane side of the partition. Understand that it is possible.

In accordance with one feature of the invention, which is particularly applicable to the embodiment shown in FIG. can be given. For example, counting from the left end of the board blind 10, each odd-numbered partition can be of five relatively bright colors, such as white or other bright colors. Each of the even numbered partitions may be a relatively dark color, such as brown or other contrasting color. In this way, the visual image created by the contoured partition and the light incident on the inwardly facing sides of the partition can be significantly enhanced. By providing partitions of alternating contrasting colors,
Particularly when the partition is in the closed or substantially closed position, the visual image created by natural light passing through the partition, which is generally partially open, is incident on the inwardly facing sides of the partition from within the corresponding room. It can also be obtained by artificial light. This feature of arranging partitions of alternating contrasting colors can also be applied to the embodiments of the invention described below.

FIG. 4 is a partial perspective view of a vertical partition board slat 20 that includes a plurality of generally flat vertical partitions 22 constructed in accordance with another embodiment of the present invention. Like partition 12, partition 22 is supported from its upper end through a support track and an associated partition support arrangement (not shown).
The partition can be moved between an open board stub position and a closed board stub position, and the partition can be rotated about its longitudinal axis between a closed partition position and an open partition position to pass through the line board stub. You can adjust the amount of light. The partition 22 has longitudinal edges 22a and 22b, at least one of which (preferably the inward longitudinal edge 22a) has a non-linear, in other words a curved, contour.

In the embodiment of FIG. 4, the inward longitudinal edge 2 of the vertical partition
2a has an irregular longitudinal profile curvature, and the inner profile edges 22a of each pair of adjacent vertical partitions are different. The outer longitudinal edge 22b of each partition 22 may be formed as a straight edge parallel to the longitudinal axis of the partition, or as an irregularly contoured curved shape similar to the corresponding inward longitudinal edge. It is something that can be done. In this way, when the partition is in a fully or partially open partition position, the light emitted through the wire screen blind is incident on the inwardly facing side of the partition and the iron sheet blind is relative to the plane of the partition. is observed from inside the corresponding room at an angle of inclination of, for example, between about 45° and 90°, so that when the inner edges of each partition visually overlap the sides of the adjacent rear partition, a chaotic abstraction occurs. A nearly three-dimensional optical illusion effect of the target image occurs across the horizontal width of the iron plate blind.

By rotating the partition around its vertical axis, the board blinds 20
It will be appreciated that the optical illusion effect created by the contoured partition 22 can be varied to selectively adjust the amount of light radiated through and incident on the corresponding inwardly facing planar side of the partition. , shows another embodiment of a vertical partition template sash 30 using contoured vertical partitions in accordance with the present invention.

Selected vertical partitions 32 (preferably all partitions 32) are configured such that at least their inwardly directed longitudinal edges 32a have a non-linear profile. In the embodiment of FIG. 5, the inner longitudinal edge 32a is formed as a generally irregular curve giving the appearance of a somewhat jagged longitudinal edge. Partition 3
The outward longitudinal edges opposite 2 (one of which is designated 3, 2 b) can be used as straight edges or as inner edges 3
Similar to 2a, it can be formed into a non-linear contour shape. when light is selectively emitted through a contoured vertical partition and impinges on a common flat inward facing side of the partition from within the corresponding room at an angle of inclination of approximately 45° to 90° relative to the plane of the partition. The contoured vertical partitions 32 create an almost three-dimensional abstract optical illusion effect when the shingle blinds are observed so that the internal edges of the partition visually overlap the sides of the adjacent rear partition.

FIG. 6 is a partial perspective view of another embodiment 40 of a vertical partition-type blind, which allows movement of the partition between an open-board blind condition and a closed-board blind condition. and from the support track by a corresponding partition support device (not shown) that allows rotation about the longitudinal axis of the partition in the closing board position to control the amount of light emitted through the vertical board. A contoured vertical partition 42 with ten end supports is used. At least one longitudinal edge of the vertical partition 42 (preferably its inward longitudinal edge 42a) is contoured in the form of a generally scalloped profile. In the embodiment of FIG. 6, the contoured longitudinal edges 42a of selected ones of the partitions 42 are in the form of negative or concave scallops, such as those formed in the partition designated 42'. , or can take the form of positive or convex scallops, such as those formed on partitions marked 42". Selectively combining partitions with positive and negative scalloped edges The orientation can be set to obtain different optical illusion effects across the width of the iron plate blind.For example, the inward vertical edges of the leftmost vertical partition and the third vertical partition from the left at 0 42° have a negative or a concave scallop profile, and the inwardly facing longitudinal edge of the intermediate vertical partition 42'' has a positive or convex seven-force wrap profile, the convex scallops being horizontally aligned with the concave scallops of the adjacent partitions. They are lined up. The partition to the right of the second partition 42'' consists of a series of positive or convex scallops offset vertically or longitudinally from each other by a distance approximately equal to half the length of the cord joining the ends of the arcuate scallops. Edge contour partition 42''. The outward longitudinal edges of the vertical partitions 42' and 42'' are formed as having a curved or scalloped profile, like their corresponding inward longitudinal edges, or parallel to the longitudinal axis of the associated partition. It is formed as a straight edge.If the vertical partitions 42'' and 42''' are arranged alternately, the partition can be observed from inside the corresponding room and light will enter the corresponding inward plane side of the partition through the blinds. An almost three-dimensional spherical optical illusion or image will then occur.
