11 Claim 1 e This invention relates to, Venetian blinds and it is primarily an object of ltheinvention,to. pro.- vide an article of this kind. withmeans, whereby a quick assembly or disassembly. may beefyfected whereby will be materially facilitated the cleansing andreplacement ofy the several parts. Astill further object of the invention is. to providev aVenetian blind. whereinA the. tapes and slats may be conveniently removed and applied', not only for the replacementof damaged' parts, but to permit substitution of parts ofselective colors for rel-decorative purposes.

Av still further object of' the invention is to. provide in Venetian blinds means whereby aliftcord may be effectively but detachably engaged" with. the. bottom cross bar and wherein the webs for the slats may be detachablysecured' to the top and bottom bars. With the above and other objects inview, the invention consists in thev details of construction and in the arrangement and combination ofparts' to behereinafter more particularlydescribed and claimed.

In order that the invention may be the better understood, reference will be had to the; accompanying drawings wherein like reference characters* denote corresponding parts in the 'severzrl'4 views; and wherein Figure 1 is a fragmentary View vpartly"invertical' sectionI and partly in elevation illustrating aa Venetian blind in accordance with an embodiment-oftiieimfenl'ion;E

As illustrated in the accompanying drawing denotes the upper bar of a- Venetian blind adapted-2 for mountingin-theusual way; and-iB denotes the conventional-lower bar:

- Each end` portionn of the top bar A in desired mem- .unapplied of 2 location is provided with a chamfered opening I, through which freely passes inv a well. known manner a usual pulling or operatingcord C. Disposed over this opening I, is an elongated plate P, of a length to extend over the opening. I and to permit the end barbs 2, struck therefrom, to penetrate the bar A, to` maintain the plate P in position. The plate P has an opening or. slot 3, disposed transversely thereacross andv in register vwith the opening I and. through whichI the cord C also freely passes.

' 'Eachof the opposite. ends of the slotS, is provided with the depending. projections struck from thev plate P, in the production of the slot 3.. Theprojections 4, penetrate the upper beveled face a of the. opening. I, to provide further means for holding the plate Pin place. f The side margins. oi. the plate P,A are defined" by the upwardly disposed iianges 5,,vwhich extend' lengthwise of the bar A, and the opposed faces of the flanges 5, in cross section are disposed on inbows to provide clamping jaws. for extremities. of. the usual slat webs. or straps W, 'which are held to the jaws -by the clamping element E. As' shown in the drawings, this element E', is substantially rectangular and comprises the elongated. side clamping bars 6 having their extremities... connected` by the interposed arcuate spring bars 1 which assure the bars 6 having desired coaction with the flanges 5 and the interposed" portions of the webs W.

The webs W coact in a well known manner with the kslats S and for which reason a detailed description and illustration in connection there'- with is believed unnecessary other than to state each of the slats Sv is separately and independentlymountedl The bar B, below an opening I of the upper bar' A, is provided with an opening li, whichv has' freely and substantially snugly inserted. therethrough 'an elongated'holding or s'ocketmernber H. This member I-I has one end 9v closed and such end is downwardly'disposed when the memberlis applied'. The opposite or open end of the member H is deiined by an inwardly dis'- posed lip Ill which provides an inwardly facing' shoulder' b for the purpose hereinafter more particularly set forth'.

Engaged with the lower extremity of the' cord Cisagripj element' G comprising two side plates ofthe plate opposite from the tooth oftheotherv plate. This is important as a greater number of thebers of the cordr will be engaged Without weakening the connection.

After the member Gr has' been engaged. with.

the cord., such'y member is forced into the mem.-

3 ber H through the open end until the outer or free end edges of the plates Il can engage the shoulder and thereby securely connect the cord C, with the member H.

The lower` or under portion of the opening 8, of the bar B is materially enlarged as at I6. to provide a chamber in which is applied from below an upstanding collar l1 of required dimension which defines an opening I8, in the central portion of a rectangular plate R, which underlies the bar B and extends lengthwise thereof. The opposite end portions of the plate R have struck therefrom the barbs E9 which penetrate the bar B from below to maintain the plate R in position. The upstanding collar I1 has on opposite sides thereof outwardly pressed ridges lla which engage the side of the opening 8 of the bar B to prevent the plate R from rotating. The opposite end portions of the collar l'i have struck therefrom the barbs lib which penetrate the side of the opening 3 and prevent the accidental removal of the plate R from the bar B.

The plate R is provided along the opposite longitudinal margins with the outstanding flanges 26 disposed lengthwise of the bar B and which also have opposed faces disposed in inbows which provide jaws whereby the lower extremities of the webs W may be detachably held to the plate by the clamping element E', similar to the element E hereinbefore referred.

The bottom or closed end portion of the member H, is provided with a filler 2| of lead or other desired material to give added weight to said bottom or closed end portion. It is important to note that this rlller 2l is provided with an opening 2lb which acts as a drain and ventilator to prevent rust and corrosion of the element H, especially in certain high humidity climates. The closed end portion of the member G, inwardly of but in' relatively close proximity to the closed end 9, is provided therearound with an annular groove 22 providing an inwardly or upwardly facing iiat shoulder 23.

The outer marginal portion of the flange or collar l1 is deiined by an inwardly disposed continuous ange 24 affording a central opening 25 of a diameter materially less than that of the opening I8 and with the opening 25 substantially central of the opening I8. When the plate R is applied, the ange 2-4 is innermost as illustrated in Figure 1, of the drawing.

Substantially snugly received from below within the chamber afforded by the collar I7 and flange 24 is a holding or retaining member R having a central opening 26 into which snugly engages from above the member H with the shoulder 23 thereof upwardly directed or in a direction toward the opening 8. A portion of the periphery of the member R is provided with a circumferentially-disposed groove 21 through the base portion of which are provided spaced openings aligning with the space openings 28 in the opposite portion of the member R. The openings are spaced apart a distance less than the major transverse diameter of the member 8 but in excess of the mean diameter of the groove 22 of the member 3. Insertable through these openings 26 are the substantially parallel pins 28' which are received within the groove 22 and provide means for effectively holding the member I-I to the member R.

As illustrated in Figure 9, of the drawing, the pins 28 are in continuation of the crossed barsl 29 which are directed through a chordal slot 30 divided in an end face of the member R and in4 communication with the groove 21. These crossed bars 29 are substantially perpendicularly related to the pins 28 and are in continuation of a split ring 3| in a plane substantially parallel to the pins 28' and positioned closely adjacent to the member R and disposed around the opening 26 thereof.

As illustrated in Figure 10 of the drawing, the holding or retaining member M is provided with the opposed pairs of openings 32, with the openings of each pair spaced apart as hereinbefore noted with respect to the openings 26 of the member R. Insertable through the openings 32 are the pins 33 which are received within the groove of the member H to hold such member H against separation with respect to the member R. These pins 33 are substantially parallel to the plane of the open loop 34 overlying a face of the member M with adjacent ends of the pins 33 connected to the extremities of thev loop 34 by the intermediate arms 35 substantially at right angles to the loop 34 and pins 33.

In the embodiment of the invention as illustrated in Figure l0, the member M is of one piece whereas in the form of the member R as particularly illustrated in Figure 9, such member comprises a number of overlying plates a held in desired assembly relationship by the rivets 36 or as otherwise preferred.

From the foregoing description it is thought to be obvious that a Venetian blind constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.

I claim:

In a Venetian blind, an upper bar, a lower` bar, said upper bar having a chamfered opening therethrough, a pull cord disposed through said opening and extending and secured to the lower a bar, a plate positioned upon the upper bar and disposed over the opening, said plate having an opening registering with the opening of the upper bar and through which the pull cord is extended, projections depending from the plate at its margins and impinging the top side of the upper bar I 3 at opposite sides of the opening therein, upstand- Number Name Date 1,910,335 Hopp May 23, 1933 2,086,461 Began July 6, 1937 2,100,648 Lawson et al Nov. 30, 1937 2,111,980 Lawson et al Mar. 22, 1938 2,166,301 Konen July 18, 1939 2,224,943 Wheeler Dec. 17, 1940 2,391,904 Junkunc Jan. 1, 1946 2,485,217 Sernilof Oct. 18, 1949 ing clamping jaws carried by the plate at opposite sides of the opening in the same and extending lengthwise of the upper bar, slats interposed between the upper and lower bars. elongated webs at opposite sides of the slats and operatively engaged therewith, the upper portions of the webs overlying the opposed faces of the jaws, a clamping element interposed between the jaws and holding the Webs at the jaws, and means for securing the opposite end portions of the webs to the lower bar.
