VENETIAN BLIND Filed Aug. 4, 1941 y 0 7a 1 :E E "L E 9 1 E 1 A. v v Md 0 a ATTORNEYS PatentedDee. 19, 1944 V ,OFFIcE 'VENETIAN BLIND August F. Christiani, Red Lodge, Mont. J Application August/i, 1941, Serial No. 405,399
' 2 Claims; (Cl. 205 2) This invention relates to Venetian blinds, and its general object is top-rovide a blind that is primarily designed for use with hinged window sash, and to be carried thereby, as well as detachably-securedthereto, in a manner whereby the blind canbe readily applied and removed, 'so as to facilitate washing the sash, but casual removal or displacement is practically impossible. "A further object is to provide a Venetian blind that includes a frame and a ladder tape'for supporting the slats of the blindat their ends and intermediate their ends for adjustment of. the slats to open and closed positions, and the slats canbe readily removed for-repairs or replacement.
Another object is to provide a Venetian blind that is simple in construction, inexpensive to manufacture, easy to install, and extremely efficient in operation, use and service.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is a front view of the blind which forms the subject matter of the present invention, with the slats in fully open position.
Figure 2 is an end view of the blind attached fora portion of their width, from their outer longitudinal edges, as best shown in Figure. 1.
The slots are. adapted to. receive the shanks of.
right angle screw hooks 4 that are threaded in the sash, and by that construction, it will be obvious that the blind is not only carried by the sash, but can be readily appliedand removed with respect thereto, the blind being held in place against casual removal or displacement when-the heads 5 of the hooks aredirected toward each other, or in other words in-latched position, and bearing against the front face of the bars I,
and when it is desired to-remove the blind, the
to a sash, and illustrates parts broken away and in section. t
Figure 3 is a top plan view. V
Figure 4 is a perspective view of one of the slats. 1
Figure 5 is a fragmentary detail perspective view illustrating the arrangement of the cross strips of the ladder tape and their relation with the slats.
Referring to the drawing in detail, it will be noted that my blind includes a frame which may be of any size and shape to fit sashes of various sizes and shapes, but in any event is made up of upper and lower bars I and side bars 2 joined together so that the rear faces of all of the bars are flush with each other to provide a fiat rear surface to bear against the inner face of awindow sash A of the hinged or swinging type, as indicated in Figure 2.
The blind is shown as being detachably secured to the sash, and for that purpose, the upper and lower bars I are each provided with a pair of slots 3 extending transversely thereof hooks'are turned fordisposal of the heads away from each other or in a released position to allow passage of the heads through the slots.
The side bars which preferably have their upper and lower ends rounded, as best shown in Figure 2, are of a width to extend a considerable dfstance forwardly of the upper and lower bars, and the side bars are each provided with a rowof equi-distantly arranged circular open ings 6 along the length thereof to provide bear.- ings for the trunnions I of slats 8. The slats are of course flat and relatively thin andare made from any flexible material suitable for the purpose. The trunnions which are also fiat are provided merely by cutting away the corner portions of the slats in right angle formation, in a manner so that the trunnions extend centrally from the ends of the slats, as best shown in Figure 4. While the trunnions are rotatably mounted in the bearing openings 6, they are of a width to set up a slight frictional engagement with the walls of the openings, so'that the slats will remain in any position in which they are adjusted.
The slats are connected together for adjustment in unison, when any one of the slats is i moved, and for that purpose I provide a ladder tape or web that includes a relatively wide continuous single strip 9 of any suitable material,
that is looped about the upper and lower slats for the other slats for engagement with the fiat faces thereof, and the strips l l are alternately arranged relative to each other, that is every other strip H is flush with one side edge of the parallel portions I0 and the remaining strips H are flush with the opposite side edges thereof, as best shown in Figure 1. The fastened end portions of companion cross strips are preferably arranged in opposite directions, as best shown in Figure 2, that is the end portions of one companion cross strip are directed downwardly while the end portions of the otherrcompanionstrip are directed upwardly, so as to allow free insertion ofthe' slats between the companion strips, as will be apparent, when it is desired to replace broken or otherwise dam-- aged slats. The fastened end portions of the strips l l for the upper and lower slats are likewise arranged to facilitate easy insertion of.slats be tween those strips and the transverse portions of the strip 9.
It is thought from the foregoing description .that the advantages and novel features of'the invention.- will be readilwapparentr .t
It isito be understood that changemmam be ,madeaini the construction andinzthez combination and: arrangement of? thee several: parts; provided that snch changesifall'swithin' the scopeaof the appended claims;
