Fiiad Oct. 6, 1958 4 Sheets-Sheet 4 a/gy'z/imnm r M Afiysz Patented Jan. 16, 1940 This invention relates to alarm v vamrmn amm Michael L. Keener, Chicago. Ill. Application a, 1m. Serial No. 233.514
'3 claims. (cl. 150-11) venetian blind constructions of the type illustrated in the patent of Michael L. Kesner, 1934, which has the louver guide No. 1,951,659 of March 20,
characteristic of V-shaped channelsin side frames. These guide members receive mitered ends of the blind louvers, keeping the louvers in alignment against swaying in any direction or rattling while oscillate on their own horizoning the louvers to tal axes to open, shut allowor intermediate positions.
Improvements on the patented construction are herein disclosed, and
relate mainly to an alteration of the mounting of the V-channel guide elements, whereinthese fixed but constitute the elements are no longer side members of a piv oted louver frame; enabling the entire blind construction to be swun inwardly away from the window frame so as not to interfere with washing and adjustment or repairs to the window.
Other objects of'the Venetian blind construction with invention are to provide a an independent expansible and contractible frame whereby the blind unit may be c orrectly fitted to window frames having a slight variation from standard for the specified size of the window;
to provide detail improvements such as the construction for supporting the louver unit and associated with operating means providing for an exactuniform angular adjustment of the louvers around their longitudinal axes; and the provision of friction grip elements of V-section or conical fitting the V-channels and allowing. the blind to be freely drawn to any position or to travel up more-orless under the action be retained in the position where it is released.
The objects of the invention construction as illustrated wherein Figure 1 is a face view of of a spring roller, and to are attained by a in the drawings the construction installed in a window frame; the latter being shown broken away.

Fig. 10 is a fragmentary front view indicating the relationship between the spring roller, top rail of blind unit and support brackets.
Fig. 11 is .an'end view of a casing for the friction holder.
As indicated by the above-mentioned objects of the invention, the general features of the construction illustrated include, a Venetian blind frame which is adjustable to an angle with the window frame which the blind fits; means for insuring absence of rattle; retention of the blind louvers in any partially collapsed position in their guides; provision for all necessary adjustments. for an exact fit to a window; and provision for general ease of manipulation of the blind.
The drawings show the blind construction mounted within a window frame I. An outer fixed frame 2 of the blind construction is attached to the inner surface of the window frame, inside the window. This outer blind frame 2 includes 1 dimensions. The side elements have welded thereto the brackets I and 9, Figs. 8 and 9. Bracket 8 is slotted at II for the reception of the squareended trunnion ll of a spring roller l2. At its opposite end, the spring roller has the customary round trunnion ii for fitting the round apertur or leader slat ,I'igs. 11 and is also supp rted by the brackets 8 and 9'. At its left-handv end, Fig. 10, the leader slat carries atrunnion liflttlngopeningrliinbracket U and'at its right-hand end carries a tongue I! flttingaslot ll,Fig.9,inanarm lflofabent The gear is pivoted on a pin 2| carried'bybracket 9 and the teeth of thisgearmeshwithawormilcarriedbyarod A heavy'top rail its motion as below the slats bracket 41 welded to frame structure 2.
I is known as a curtain or blind 23. This rod has a knurled operating head and bearings in earsv of bracket 3.
By turning the knurled head, theleader slat I 4 is adjusted angularly on its longitudinal axis and through the tapes 26, Figs. 1 and 3, transmits is customary to the louvers 21.
members connect the tapes on of the slats and pass above and so as to positively transmit motion from the leader slats to the others.
The. spring roller t2 is permitted to operate to draw .the slats upwardly by squeezing the grips .23 of a friction-holdingdevice shown in Figs. 1, 2'and 4. This holding device carries friction cones 28 of Fig. 3, or the elongated beveled friction elements 3| of Figs. 1', 2 and 4, for engagement with guide channels 32 for the louvers. The friction elements are preferably made of rubber and are pressed outwardly by springs 33.
The guide channels32 are formed in louver frame elements 34 and 35 which are hung from the side members 3 of fixed frame 2, by pivot pins 36 and 37.
The channel members 34 and 35 are connected at their lower ends by a multi-part transverse frame member 33 constructed for lengthwise expansion or contraction, as illustrated in Figs. 5, 6 and 7. Screws 39 are accessible through openings 40 in the members 4| of transverse frame 33 through slot". The interfitting elements of this lower frame may he slid slightly length- Transverse tie opposite sides .wise or each -other and then clamped together by screws 39. This allows for the inner louvercarrying frame to be adjusted according to the adjustment of the outer bracket carrying frame 2.
The hinged blind unit is normally retained in the vertical position by spring bullet latches 43, Fig. 3, which engage recesses 44 in the blind frame.
The blind may, however, be swung outwardly as indicated in Fig. 3 and retained in that position by arms 45 which are pivotedat 46 to a These arms are normally suspended in vertical position out of view but may be positioned to engage notches 48 in the louveQr guide elements 34 and 35.
The friction holding device 30, shown in Fig. 4, fixture and the common construction includes a pair of spring- Dressed elements for engagement with the window frame. In the dsclosure now made that construction is modified so that the friction elements 3| are of suitable cross section to travel in and engage the 'V-channels 32. Elements 3| carry guide pins 43 in a wood casing 50 for fixture 33. This fixture also provides an anchoring means for metallic tapes 5| which lead from the fixture upwardly through slots in the louvers to 'thespring roller Themetal tapesSl are preferably located to-be covered by the ladder tapes 28.
The operation of the construction is similar to spring roller-shades in that it is drawn down by grasping the grips 29. When these are released slidable in apertures formed the leader slat is communicated through the ladder tapes 26 to the louvers 21.
The blind and its frame structure may be swung on its pivots 36 and 31 clear of the window in an inward direction and retained in the moved position by arms 45. Access to' the window may thus be had without interference from the blind.
The V-channelled frame structure which swings from the fixed frame constitutes a. support for each and all of the louvers holdings them against sag when the blind is swung inwardly from the fixed frame, and serve as guides forthe louvers when they are slid upwardly or downwardly and also serve as end bearing supports for the louvers when the louvers are turned angularly on their longitudinal axes.
The ladder tapes 26 are secured to what is known in the art as upper and lower rails. The lower rail, generally constructed about the same as a louver, but heavier and the upper rail, herein referred to as the leader slat, are turnable as a unit with the louvers on their longitudinal axes. I
I claim:
1. A blind construction of the class described including a set of louvers with flexible suspension connections between the louvers, a frame structure for the louvers including channel elements of V-section for guiding the louvers, and resiliently mounted conical grip elements connected with the louvers and engageable with the V-channels for retaining the louvers in'any desired set position in the blind frame. I
2. A Venetian blind construction including a set of louvers with flexible suspension conections between the louver a frame structure for the louvers including channelled guide elements of bers providing for adjustment of the lateral spacing of said side members, a U-shaped blind guiding frame having side members pivoted at their upper ends to the fixed frame and a bottom connecting member formed of relatively slidable elements whereby the spacing between the side .members of the blind guiding frame may be varied.
