VENETIAN BLIND Filed Nov. 12, 1935 Jsl l PM Mar. 19, 1940 UNITED STATES vm'rms sum) John D. Feeney, Downers Grove, Ill., assigns to Sears. Roebuck and 00., Chicago, 111., a corporation of New York Application November 12, 1938, Serial No. 110.448
O-Oilllnl.
This application is in part a continuation of my copending application Serial No. 64,809. flied February 1'1, 1936.
, My invention relates to Venetian .blinds. Such 5 devices are usually constructed of a plurality of slats formed of fiat strips of wood or the like, said slats being suspended in parallel relation. The blind may be controlled as to the angle of the slats by tilting and also as to the window 19 area covered by raising and lowering the slats from the bottom of the device. According to the standard construction of Venetian blinds, each slat is provided with apertures for the passage of suspension ropes. The slats are not removable from the ropes, and hence the cleaning and repair of-such devices are diificult and awkward, involving removal of the ropes from their. pulleys and dismantling the'entire blind, involving considerable time and annoyance.
An object of my invention is to provide an improved. Venetian blind having slats which are individually removable from the suspending ropes by a slight movement, without the necessity of disturbing other slats or any of the gear.
A further object is to provide a blind having slats of the type referred to which will be securely carried by the ropes, in spite of their quick removability therefrom, and not easily removed therefrom by accident, as by the wind,
etc.
Various other objects and advantages will become apparent as the description proceeds.
Referring now to the drawing illustrating a preferred embodiment of my invention, and forming a part of this specification;
Fig. l is a front elevation of a Venetian blind embodying my invention;
Fig. 2 is a top plan view thereof;
Fig. 3 is a sectional view taken substantially along the line 3-3 of Fig. 1;
Fig. 4 is a sectional view taken substantially along the line 44 of Fig. l; and
Fig. 5 is a sectional view taken substantially 5 along the line 55 of Fig. 1.
The numeral [0 represents a suspension board of a Venetian blind, said board being adapted to be secured adjacent a window or the like. Said board is provided with a longitudinal channel i2 50 in its upper surface and is notched adjacent one end as at i5. Secured to the board I0 is a brackat I 5 pivotally mounting a pulley it over which are trained ropes l8, l8,'these ropes being trained also over longitudinally spaced pulleys 25,
I which are Journalled on shafts 2|, ii. on opposite sides of the channel l2. A corrugated roller l1 carried in the bracket l5 rides against the ropes II, II and serves as a detent. Depending from the bracket I5 is a finger 22 separating the ropes l5, ll. 5
Also attached to the board I0 is a bracket 25 (Figs. 1 and 5) which carries a pulley 28, said pulley being disposed within a protective housing 21. Threaded around said pulleyffl is a rope 25. Arranged on the shaft 28 of said pulley 25 is a worm 80 meshing with a worm wheel 2i. Said worm wheel ii is rigidly carried on a rod 32 secured to a tilt bar 35, said rod being pivotally journalled in the bracket 25. Said tilt bar 35 is also provided with a pintleufl which is jouru nalled in a bayonet slot formed in a depending bracket 38 secured to the underside of the suspension board ill.
Secured to the tilt bar 55 in longitudinally spaced relation is a pair of tapes 40, 40 secured 90 to the tilt bar as by means of tacks M or the like, these tapes being formed of fabric of any suitable type and extending downwardly from the" tilt bar 25 and around a bottom bar 42, to which they are secured as by tacks 43. Con- 25 necting the opposite sides of the tapes 40 intermediate the bars 55 and 42 are webs 45, said webs supporting slats 41.
As shownin Fig. 3, the tilt bar 35 is provided with spaced elongated apertures 50 for passage of the ropes l8, l8, said apertures 50 being not only spaced from each other longitudinally of the bar, but also staggered with reference to the edges thereof.
Referring to Fig.4, it will be seen that the slats 41 are likewise provided with apertures 52, 52, said apertures being spaced to correspond with the apertures 50 of the tilt bar 35. Each of the apertures 52 of the slats is connected with the proximate edge of the slat 41 by means of a diagonal and preferably straight channel 53. It will be seen that the channels 53 are approximately tangential to the apertures 52 and join a corner of the aperture adjacent the proximate edge of the slat.
The ropes l8, ii are led over the pulleys 20, 20' through the apertures 50, of the tilt bar 35 and through the apertures 52, 52- of the slats and secured to the bottom bar 42 as by knots disposed in countersinks 55 (see Fig. 5).
The operation of the device will be obvious. By manipulation of the rope 25 acting on pulley 28, worm 20, and gear Ii, the tilt bar 35 is rotated about its axis, thus tilting the slats 41 through the medium of the tape 40 and webs 45. By 55 manipulation of the ropes II, I! the slats are raised or lowered.
It will be seen that the slats 41 are individually detachable from the ropes II, II through the slots 53. At the same time, by reason of the peculiar construction and arrangement 01' the slots and the notches the slats are quite secure and are not easily disengaged by accident. However, when it is desired to remove a slat for cleaning or repair, the ropes may readily be slipped out of the slots through the channels or notches 53.
Changes coming within the spirit 0! my invention may suggest themselves to those skilled in the art and hence I do not wish to be limited to the specific form shown or uses mentioned ex cept to the extent indicated in the appended claims, which are to be interpreted as broadly as the state of the art will permit.
I claim:
1. In a Venetian blind, a removable slat having a pair oi spaced rope receiving apertures staggered with reference to the longitudinal center line of the slat, each aperture communicating with the proximate longitudinal edge of said slat by means of a straight, oblique channel communicating with a corner of said aperture adjacent said proximate edge.
