' VENETIAN BLIND SLAT mad Aug. 21, 1945 I gnfimint MORE/5140885 YfLL/OTZ Patented Oct. 14, 1947 UNITED STATES PATENT mm VENETIAN BLIND SLAT Morris Aubrey Elliott, Baltimore, Md. Application August 21, 1945, Serial No. 611,849 2 Claims. (01.160-173) This invention refers to Venetian blinds and more particularly to a manner of removing and replacing the laths or'so-called slats for cleaning without disturbing the operating cords and straps and other mechanism connected with the Venetian blinds.
Theconventional manner of tieing the slats of a Venetian blind together is done by threading ropes through rectangular slots in the slats. The disadvantage of this arrangement is that it requires considerable care, labor and time, and in case of repair or the removal ofslats for cleaning incurs appreciable expense. The general object of this invention is to provide a new and improved Venetian blind slat that will avoid one or more of the disadvantages and limitations of the prior art. I
Another object of the present invention is to provide a new and improved Venetian slat that can be connected to other slats of the same type in an expeditious and facile manner.
A particular form of the invention. is indicated 'in the attached drawings and described in the specification, in which further objects will become apparent while the scope of the invention is covered in the appended claims.
In the drawings:
Figure 1 is a plan view of avenetian blind slat embodying this invention, and
Figure 2 is an end view in perspective showing the main slot and lateral slot in an end of the Venetian blind slat.
Similar reference characters refer to similar parts throughout the drawings.
In the drawings i0 is a conventional Venetian blind slat, having a main slot II for the usual operating cords I 2 used for raising and lowering the blind. The slots II are provided with angular edges ii to give the slat a wider angle of adjustment without interfering with the proper operation of the operating cords. A lateral slot It runs at approximately right angles from the main slot ii to the end of the slat IO. where it opens up to allow the operating cords to be inserted through or removed readily. The faces Y I! and i6 respectively of the slot and the faces ll and i8 01 the same slot I I are formed at plural come within the scope of \the appended claims. t
Having thus described the invention what is.
angles as indicated to produce two planes. These tend to bend the operating cords when moved through the slots and obstruct their removal by ordinary movements of the slats in use, which would tend to occur if the slot surfaces were straight. The edges of the slat are preferably relatively straight as they are more effective in that form.
While but one general form of the invention is shown in the drawings and described in the specification it is not desired to limit this application to this particular form or in any other way otherwise than limited by the scope thereof, as it is appreciated that other forms could be made that would use the same principles and claimed is:
1. A slat for a Venetian blind having an end portion provided with a main slot therein for an operating cord to pass therethrough in a direction transversely to the section thereof, and an entering lateral slot at right angles to the main slot having its plural surfaces angularly arranged to its entering direction.
2. A slat of the class described including a main transverse slot with angular edges for an operating cord to pass therethrough, a lateral longitudinal slot for threading the cord from an endtherethrough, said lateral slot having its opposing surfaces positioned parallel with each other for part of the distance through the thickness of the slat and the direction of the parallel Y faces for the remaining part of said. distance positioned angularly to the first mentioned portion of said lateral slot to restrict the withdrawal of the cord therethrough from the main slot.
