2 Claims. 1

The present invention relates to new and useful improvements in Venetian blinds and more particularly to a novel tilting mechanism for a group of the slats wherein the same may be closed independently of the remaining slats.

Frequently it is desired to close some of the slats of the blind, such as the slats at the lower half of the blind, to afiord privacy, while the slats at the upper half of the blind remain open to provide ventilation and accordingly the primary object of the present invention is to provide a Venetian blind construction whereby this result is accomplished.

An important object of the invention is to provide an auxiliary slat tilting mechanism which may be operated independently of the usualmain tilting mechanism which remains unchanged.

Another object is to provide an auxiliary slat tilting mechanism for a predetermined number of the slats which may be installed on the blind without necessitating any changes or alterations in the construction thereof, and which is simple, practical, and efiicient in its construction and operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

e Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view;

Figure 2 is an enlarged vertical sectional View taken on a line 2-2 of Figure 1;

Figure 3 and 4 are enlarged fragmentary vertical sectional views taken respectively on the lines 33 and 4-4 of Figure 1;

Figure 5 is a top plan view;

Figure 6 is an enlarged horizontal sectional view taken on a line 66 of Figure 1 and;

Figure 7 is a perspective view of the main and auxiliary slat tilting mechanism.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a conventional type of Venetian blind generally and which includes the usual headboard 6, upper tilting board 1, lower tilting board 8, front and rear tapes 9 and I0 attached at its upper and lower ends to the upper and lower tilting boards and to which the slats I I are attached for tilting by the cord l2 and pulley I3 connected to the upper board "I. The slats are raised and lowered bodily by the usual cord I 4 trained over pulleys I5 and connected to lower board 8.

The present invention comprises a roller or drum I6 rotatably supported in brackets I! attached on top of headboard 6 and to which the upper ends of cords [8 are attached for winding thereon, the cords I8 passing downwardly through openings I9 in the respective front tapes 9 to position the cords behind the front tapes and the cords are then attached to the tapes by again passing the cords through the tapes and knotting the cords in front of the tapes at a desired location, as shown at 20.

Roller or drum I6 is rotated by a cord 2| and pulley 22 connected to one end of the roller or drum by a worm and worm gear (not shown) in a housing 23 supported on headboard 6.

By operating cord 2!, the roller or drum IE will be rotated to wind cords l8 thereon and thus raise the lower portion of front tapes 9 and to which a lower group 24 of the slats II are attached for tilting the same to a closed position, while the remaining slats forming an upper group 25 remain open.

Both the upper and lower groups of slats may be simultaneously closed by the operation of cord l2 of the main tilting mechanism.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed asnew is:

1. A Venetian blind including a fixed head board an upper slat tilting board supported a beneath the head board, front and rear groups of tapes attached to the tilting board, slots supported by the tapes for tilting movement, a main slat tilting mechanism supported by the head board and connected to the tilting board for simultaneously tilting all of the slats, roller brackets attached on top of the head board, a roller journaled in said brackets, and flexible members wound on the roller and connected to one group of tapes at a point between the uppermost and lowermost slats for opening and closing the group of slats positioned below the connected ends of said flexible members independently of the remaining slats.

2. A Venetian blind including an upper slat tilting board, front and rear tapes attached to the board, slats supported by the tapes for tilting movement, a main slat tilting mechanism connected to the board for simultaneously tilting all of the slats, and an auxiliary slat tilting mechanism connected to one of the tapes for opening and closing a group of the slats independently of the remaining slats said auxiliary slat tilting mechanism comprising a roller supported at the top of the blind, cords connected to the roller for winding thereon and also connected to one of the tapes to raise the lower portion thereof, and an operating cord for the roller.
