6 Claims. (Cl. 160-118) My invention relates to adjustable window blinds of the type commonly known as Venetian blinds.
My invention relates more particularly to Venetian blinds of the type that are adapted to be suspended vertically rather than the usual horizontal position.
The principal object of the present invention is to provide universally adjustable Venetian blinds of the type which may be vertically suspended in a window, may be opened or closed, partially opened or closed, draped from the top towards both sides of the bottom of the window, or as a body slid to the side of the window so that there is no apparent blind of any kind in front of the window.
Heretotore applicant has provided various constructions of vertical Venetian blinds, blinds which have included adjustments whereby they may be turned about a vertical axis to control the amount and direction of light and air, or may be gathered or draped at the lower end.
The present invention goes one step further in that it now provides mechanism for moving a plurality of normally vertically disposed slats or shutters sideways to permit disclosing practically the entire window and presenting the effect of having no blinds whatsoever hanging in front of the same.
A further object of the invention is to provide multipally adjustable vertical Venetian blinds which include two sets of equally spaced vertically disposed blinds mounted in a unitary frame adapted to be hung in the window frame.
A further object of the invention is to provide an improved multipally adjustable vertical Venetian blind which includes a pair of sets of vertically `disposed slats or shutters and identical mechanism associated with each for controlling both the location and position of its particular set of slats, both sets being mounted in a unitary frame capable of being suspended in a window frame.
Other objects and advantages will be more apparent from the following description wherein reference is had to the accompanying sheets of drawings, upon which Fig. l is a front elevational view showing one of the multipally adjustable vertical Venetian blind units mounted in position in a window frame;
Fig. 2 is a vertical sectional view thereof taken on the line 2-2 of Fig. 1;
Fig. 3 is a side elevational view of the parts shown in Fig. 2 with portions broken away to more clearly show other parts;
Fig. 4 is a plan sectional view taken on the line 4-4 of Fig. 2;
Fig. 5 is a fragmentary side elevational view of the parts shown in Fig. 4;
Fig. 6 to Fig. 13 inclusive are generally diagrammatic views showing the various combinations or window eiects which may be accomplished by employing the construction which I provide, and are described as follows:
In Fig. 6 both sets of shutters are in their vertical open position;
In Fig. 7 both sets of shutters are closed to exclude air and light;
ICC
Fig. 8 shows both sets of shutters as draped toward the bottom;
In Fig. 9 both sets of shutters are pushed to the side as tar as possible, generally exposing most of the window surface to direct air and light;
In Fig. 10 the left shutter is swung to the left as far as possible to permit air and light to enter, and the right shutter is hung in the normal vertical position;
In Fig. 11 the left shutter is shown with the vertical slats turned about their -axis to completely shut out air and light, and the right shutter is moved entirely to the right side, exposing the entire right half of the window to air and light;
In Fig. 12 the left shutter is completely collapsed against the left side of the frame, and the right shutter is shown in a draped position; and
In Fig. 13 the left shutter is draped toward the bottom and the right shutter is hung vertically suspended permitting air and light to enter.
In the embodiment of the invention which I have chosen to illustrate and describe the same, in Fig. l I have shown a Venetian blind unit which employs two sets of adjustable vertically disposed slat members, the unit comprising -a U-shaped frame including the two side frame members 16 and 18 connected to the top cross-frame member 20. The top cross-frame member may have a rod 22 extending through the end walls 24 and 26 of the same, the rod acting as a support for the entire unit and being supported at its ends upon suitable bracket members 28 fastened to the side walls of the window frame 36, each of the brackets 2S having an open-ended slot 32 whereby the rod 22 can be inserted from the top and permitted to settle in the slots 32.
The lower ends of the side frame members 16 and 18 may be suitably fastened to the vertical Walls of the window sill 30 by means of 'screw members 34 which extend through slots 36 in the frame and into the side of the window frames. As previously mentioned, a pair of groups of vertically disposed slats may be hung in each of the window blind umts, each set of slats S including top and bottom control members 40, best shown as units in Figs. 4 and 5.
Each of the control members or assemblies may include a pair of spaced parallel arm members 42 and 44 connected at one end by a pivoted lever 46 and at their extended ends by a slat yoke 48.
Each of the pivoted levers 46 is adapted to be mounted on a side bracket 50, the brackets having a vertical Wall 52 aligned with the inside of the side frame members 16 and 18, being fastened thereto by a screw member 53 that extends through the vertical slot 36 previously mentioned. Each of the brackets S0 also has a forwardly extending handle portion 54 capable of manual manipulation to raise and lower the assemblies 40, as will be hereinafter described.
The control members 40 associated with each set of vertical slats, may be fastened together by a vertical rod member 56 securely fastened to the upper side bracket 50 and extend through a slot 5S in the lower side bracket 50, the lower end of the rod having a pivoted wing portion 60 connected thereto so that when the wing is turned at right angles it may be passed through the elongated slot 62 in the lower bracket 50 to disconnect the same. This is necessary for certain adjustments which will be later described.
The control members 40 may have a plurality of yoke members 4S connected between the side arms 42 and 44 of the same by means of bolt members 66 which pass through openings in the sides of the arm members 42 and 44 and receive a cotter pin 68 which is dropped through a pair of arm members 70 on the sides of the yokes 48. Each of the yokes is provided with an arcuately shaped n individual axes, and-means yslot 72 through which a verticallyldisposed slat S may end slat S. Y Y n With the construction I have thus provided a number of possibilities` are readily apparent. In the iirst place,-it is obvious that the entire frame member or unit isV capable ofV being lifted otlf of the support bracketsl'fo'rwashing, repairror replacement. f
Vmember are always fixedly connected at this point to the a side frame member, turning the same about their longitudinal axes, orv draping the same adjacentV their lower ends, saidY means including a control member having arms on two sides of said slats, yoke members pivotally connected between said arms, said slats'extended through said yokes, a lever connected Yto a sideV frame member, said arms pivotally connected toV saidV lever and said lever vertically slidably mounted 1n said side frame member. Y f
2. A window blind for mounting in a rectangular window frame including a U-shaped frame having a horizontal top cross frame memberand vertical side frame Y members, a rod in said top cross-frame memberthaving its -By referring'toV Figs. 6 to I3, it' can be seen that av number of interesting and desirable adjustments. can be made. i Fonexample, in Fig, 16,' theV Venetian blind asy Vsembly is shownV with all of the 'slats S vertically disposed Yfrom the rod 22 to permit the'imaximum'of' daylight to beL introduced'through 'therwindow frame.Y By moving each of the control members sideways, the slats S are rotated about their verticalaxis suiiciently to effect a completeclosure of the space inthe window frame. This Y may be done by reasono'f the fact that each of the slats is provided with the elongated slot 91 so that it can hang from Ythe, cross-rod 22, be angularly moved thereon, Vor rotated throughl a large radiuson the same. yIn Fig: 8 I have shown both of` the lower control merm-V bers 4G loosened from the vertical rod 56 and moved downwardlyA so that a drape effect is provided by each set of vertical slats. In Fig. 9 I have shown'the slats gathered adjacent the sides of theV window.' This1 is done by moving downwardly the outer sides of the controly members 40 asa unit connected together by the vertical rod S6. In this manner the maxirnum amount of light can be secured through the window opening 30.
In Fig. 10 Iv have shown another adjustment which is possible with the construction I have provided. In this t adjustment the side assembly 93 is closed against the left window frame wall and the right assembly 95 is 'shown with theislats in the vertical position to permit light and air to pass between the same.
ends extending beyond both ends of said. top cross-frame member and `adapted to support said window bhnd onV brackets in said Ywindownframe, a plurality of vertically positioned slats, each having means for supporting saidV slat on saidrod for sliding movement longitudinally of said rod and for pivotal movementV or"V said slats on their individual axes', and means for imparting sliding movement to said slats to gather the'same together adjacent a side frame member, turning the same about their longif tudinal axes, or draping the sameV adjacentV their lower ends, said means including a control member having armsY on two sides ofvs'aid slats, yoke'menibers pivotally .con
Vnected between said arms, said slats, extended through y said yokes, a lever connected to a side yframe member, Y
said arms 'pivotally connected to said lever and said lever In Figs. 11,7712I andv 13 I have shown the other adjust# I ments in'which the unit may be placed, Fig. 11 showing t generally half of the window closed and half openQFig.
152 showing half of theV window open and the other side draped; and Fig; 13 showingV one unit with the slats hanging in a vertical position and the other unit withthe slats draped. Y
It can thusy be seen from the variety of adjustments providedV that the unit is capable of practically universal adjustment and the amount of air and light which it is desiredto secure can be controlled in a variety of ways. The window closure is thus capable. of a variety of effects which yare'not possible with any other type of Venetian blinds, drapes or window shades.Y
WhileI have* illustrated and described a specific embodiment of the invention, it will be apparent to those `sk1lled inthe art that changes and modications may be made inthe exact details shown and I do not wish to be limited in any particular; rather what I desire to secure and protect by Letters Patent of theV United States is:
