Patented Apr. 21, 1953 UNITED STATES PATENT OFFICE VENETIAN BLIND VVANE SPACER Robert S. King, Oak Park, lll.
Application December 10, 1951, Serial No. 260,865
7 Claims. Y.,(Cl. 160-172) 1 v. My invention relates to a Venetian blind of the vertical type and more particularly to a vane spacer for use therein. This type of blind has a? headf'rame with a headframe floor and vertically disposed vanes. In this type of blind it is generally contemplated that each vane Will be supported in a vertical position by an appropriate vane shaft extending through a longitudinal slot in the headframe iloor.
Each vane spacer is adapted to receive a vane' shaft so that the vane shaft and its Adepending vane may be rotated about their vertical axis.
Further, the vane spacer, which is positioned.-
above the longitudinal slot, is adapted to be moved horizontally along the headframe floor ofv proper and which may be moved in either direc tion across the face ofthe blind.
Another object of my invention'is to provide l avane spacer whereby the'vanes of a Venetian blind may be progressively spaced across the Another object is to provide a spacer that con- `:stitutes a unitarysupporting means for each vane which cooperates to move the individual vane transversely of the window and which-allows the provide Prior Venetian bIinds'haVe generally resorted to separate mechanisms to support-the vane and to effect equal spacing thereof. The'prio'r spacing means have generallybeen of -a pliable ma- Aterial such as tapes and strings which are subject "to wear and consequent periodic replacement.
Also, they tend to bind in use.
In the present structure each vaneis supported :and spaced by my unitary vane spacer. My .vane
spacer, being constructed of rigid material such the life of the blind.
understood, of cours'efthat in commercial appli- It `is to be.`
ias' metal, is not subject to wear, under ordinaryA use, and therefore need not be replaced duringy lcations of the invention various details might well vary from those here shown and described.
In the drawings:
Fig. 1 `is a perspective view, partly broken away, of the headframe iloor of a venetian blind of the vertical vane type, showing the assembly of my vane spacers;
Fig. 2 is a perspective view of a single vane spacer.
Referring to the drawings, and particularly to Fig. 1 thereof, my vane spacers are illustrated in assembled relation on headframe floor l of a vertical type Venetian blind. Floor l has a longitudinal slot 2 through which pass vane shafts I6. Slot 2 allows the vane shafts andiassociated depending vanes to move laterally of the headframe. l
A drive element l'6, located at the movable end of the assembly, is adapted to be moved backand forth along slot 2 by suitable traversing means I The illustrated embodiment-of my'vane spacer (Fig. 2) is formed from-a' single length of wire. One end of this wire is bent into a vertically-'disposed loop 2| which denes a rst horizontal aperture Il. The wire then follows a rearward course from the top of loop 2| toa point'where `it has a horizontal-U-bend 22 vwhich 'denes a `vertical opening 8 .at the rear top of the vane spacer. The wire-continues to the. front of .tlie vane spacer where it is provided with a vertical .U-bend .23, the lower leg of which. lies'in-:the :bottom plane of the vane spacer.V U-b'end 2'3 'defines a second horizontal aperture l0. The wire is then formed with a second horizontally disposed U-bend 24 which vprovides ver- .tical opening 9 at the rear ofgthe vane spacer below and in spaced relation from the first horlzontal U-bend 22. This Astructure forms a vane spacer body having two spaced sidewalls, one lcomprising vertical loop 2l and the otherl comprising vertical U-bend 23. The sidewalls have -alignedapertures i! and l0, respectively, and aperture l l is smaller than aperture ill, as shown in the drawing. The body also has a vertical opening |'8 therethrough comprising the indivi- .dual vertical opening 8 and 9 of horizontal U- .bends 22'and 24, respectively.
Drive element 6 has the same body structure as has lthus far beendescribed for the-vane spacer.
Following Ugbend 24 the wire is bent in agenerally vertical right angle bend I9 substantially midway between the frontand the rear of the Next, 4the wire is bent in alaterally extending right angle b endZ. The laterallyextendingwire length is bent in an arcuate shape to form spacing portion or spacing element 5, the free end of which is bent at a right angle to form a stop I2.
It is apparent that by means of right angle bends I9 and 20 there is formed an arcuate spacing element which extends laterally from the vertical midpoint of the smaller apertured side of the vane spacer body in a direction generally perpendicular thereto. Thus, any longitudinal force exerted on said spacing element will generally be applied to the central portion of the body.
Referring to Fig. l, it will be seen that the left hand vane spacer of the assembled series of vane spacers is engaged by an anchor 4 attached to a post 3 by means of an anchoring loop I3. Anchor 4 is comparable in size and shape to spacing element '5 of each vane spacer.
In use, each vane spacer is associated with .one end of a vane I'I. The vane end is provided with a shaft I6 (Fig. l) that extends through the vertical opening I8 in the vane spacer. A collar 25 lat the end of shaft I6 rests on the .top of the vane spacer. as shown at the right in Fig. 1, and the vane spacer rests on the headframe floor I with shaft I5 extending through slot 2. Vane rotation element 1 is integral with collar 25 and controls the degree of rotation of vane shaft i6 and its associated vane. Vertical opening i8 is large enough to allow free rotation of the vane shaft i6.
Anchor 4, the vane spacers and the drive element 6 are assembled above slot 2 of -headframe oor I. Anchor 4-is coupled to the adjacent vane spacer by slidingly passing the free end thereof through horizontal apertures I-I I of said vane spacer. Stop I2 of anchor 4 engages the peripheral edge of horizontal aperture I I formed by loop 42l of one of the sidewalls of said vane spacers when the vane spacers are moved away from each other during traverse movementas the blind is moved to its open position. In a similar manner spacing element 5 of each vane spacer is slidingly I coupled to the next adjacent vane spacer through the interaction of stop I2 and the peripheral edge of horizontal aperture I I formed by loop 2I of the sidewalls of each of said vane spacers.. The last vane spacer is similarly slidingly coupled to drive element 6, as shown.
In Fig. 1, the coupled `vane spacers are illustrated in the positions they occupy when the traversing arrangement-has been used to bring the blind to its nearly fully opened position. The traversing force has been appliedto move drive element 6 to the left. As shown, this element has fully telescoped the spacing element 5 of the adjacent vane spacer, and the latter has been .moved to the left so as to fully telescope the spacf The same is ing element 5 cf the next spacer. true of .the next three. spacers.
Additional traversing force applied to drive element 6 will bring the two separated' vane spacers together in the same mannenand finally will cause the last vane spacer to be moved to the lend of slot 2.
In this condition the blind is fully open.
As the spacing element 5 of each vane spacer telescopes the adjacent vane spacer, the. spacing element 5. swings forward, lookingat Fig. i. -This swinging motion is accommodated withoutv -bind- :ingpbecause one of the horizontal apertures in vane spacer by the amount permitted by spacing element 5. the periphery of horizontal aperture II formed by loop 2| of drive element 6 is engaged by stop I2 of the adjacent vane spacer. Continued movement of element 6 thus results also in moving the adjacent vane spacer until it in turn is engaged by stop I2 of the next vane spacer as described. This process is progressively repeated until drive element 6 has been moved to its extreme right hand position in the headframe. At this time the blind is fully closed and the individual vanes are properly spaced in the blind, anchor 4 serving to space the last vane at the extreme left (Fig. 1) as described. The spacing of each vane, as previously mentioned, is measured by the length of the spacing element 5 of each vane spacer.
From the abovedescription it is thought that the construction and advantages of my invention will be readily apparent to those skilled in the art. Various .changes in detail may be made without departing Vfrom the spirit or losing the advantages of the invention.
Having thus described my invention, whatl I claim as new and desire to secure by Letters Patent is:
