United States Patent VERTICAL JALOUSIE VANE ASSEMBLY Lee Miller, Gardena, Calif.

Application May 21, 1956, Serial No. 586,044

1 Claim. (Cl. 20-62) I This invention relates to a vertical jalousie vane, assembly and more particularly to improved pivot means for pivotally mounting a vertical jalousie vane.

It is one object of this invention to provide a vertically extending jalousie in which friction is reduced to a minimum. 7

It is another object of this invention to provide means in association with such a vertical jalousie which prevents lifting or blowing of the vanes out of the assembly.

It is a further object of this invention to provide pivot means for a vertically extending jalousie vane which is self-draining and thus prevents fillingof the pivot means with water and freezing in wintertime.

These and other objects, features and advantages will be apparent from the annexed specification, in which:

Figure 1 is a front view of a jalousie vane made in accordance with the present invention.

Figure 2 is an end View thereof.

Figure 3 is an enlarged section taken along the line 3-3 of Figure 1.

Figure 4'is an enlarged section taken along the line 4-4 of Figure 1.

Figure 5 is an enlarged section taken along the line 5-5 of Figure 1..

Referring now more particularly to the drawings, the vane is mounted between a lower channel 11 and an upper channel 12. Each vane 10 has secured thereto at the top and bottom a tilt arm 13 aflixed to the vane as by nuts 14 and bolts 15. The upper tilt arm 13 is pivoted upon a pivot pin 16 mounted in channel 12 by a bushing 17 mounted in a suitable hole in the tilt arm. An operating arm 18 is pivotally connected to tilt arm 13 by a shoulder bolt 20 threaded into a tapped hole in the oparea, friction is obviously reduced.

2 2,830,335 Patented Apr. 15, 1958 ICC crating arm, a bushing 21 being mounted in a suitable hole in the tilt arm 13. Except for a reversal of direction, the assembly at the bottom is identical with respect to the shoulder bolt connection to the operating arm and hence Figure 5 illustrates this assembly in both cases.

The lower end of the vane is pivoted upon the channel 11 as illustrated in Figure 4. A pivot 22 is aflixed in a hole in the channel, which pivot is provided with a conical bearing surface 23. A shoulder bolt 24 is threaded into a tapped opening in the pivot 22 and a bushing 25 secured in a hole in the tilt arm 13 has a line engagement with a conical surface 23 of pivot 22 as clearly illustrated in Figure 4. As this presents a minumum bearing It is also obvious that any moisture collecting upon the surface 23 of the pivot 22 will flow to the side and hence the pivot will not become filled with water which might freeze in'the wintertime.

While there has been described what is at present considered the preferred embodiment of the invention, it will be understood that various changes and alterations may be made therein without departing from the essence of the invention, and it is intended to cover herein all such changes and alterations as come within the true scope and spirit of the annexed claim.

I claim:

A jalousie comprising a vertically extending vane; a tilt arm secured to said vane means pivotally mounting said tilt arm adjacent one end thereof to an operating arm; means pivotally mounting said vane to an upper support; means pivotally mounting said tilt arm to a lower support, said last mentioned means including a conical bearing carried by said lower support and a sleeve carried by said tilt arm and engaging said conical bearing with a line contact, said conical bearing being threaded and having a shoulder bolt threaded therein to secure said sleeve on said bearing, said sleeve being mounted upon said bolt.
