Abstract

Abstract A mechanism for adjusting the tilt angle of slats of a slat blind positioned between the panes of glass of a sealed window unit is described. The mechanism is sealed about an aperture through one of the panes and includes a flexible cable within a flexible tube extending from the mechanism to the control mechanism for the blind. The flexible tube maintains the window seal and the cable enables torque to be transmitted from the mechanism to the tilt control mechanism of the blind, thereby allowing direct external mechanical control of the tilt angle of the slats without breaking the hermetic seal for the window.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 228 words
A sealed double glazed window, comprising: two spaced panes of glass sealed in a frame; a slat blind positioned in the space between the panes, the blind having slat tilt angle control means associated therewith; an aperture defined through one pane of glass providing access to the slat tilt angle control means of the blind; an adjusting device sealingly mounted about the aperture so that the tilt angle of the slats may be adjusted while maintaining thw window seal, the device comprising a plug including a threaded outer cylindrical surface extending outwardly through the aperture and having an annular flange portion engaging a surface of the pane of glass, the flange being sealed about the aperture, the plug defining a tubular portion being open at both ends thereof and extending inwardly from a planar front surface of said pulg, a flexible tube sealed about the tubular portion and extending therefrom into a sealing engagement with the slat tilt angle control means of the blind, a flexible cable being attached at one end to the tilt angle control means, said cable extending through the flexible tube and tubular portion so that the other end thereof may be manipulated to adjust the tilt angle of the slats, and a nut coacting with the threaded outer surface of the plug to provide a sealing engagement of the plug about the aperture.
Claim 2
Dependent Claim 228 words
A sealed double glazed window, comprising: two spaced panes of glass sealed in a frame; a slat blind positioned in the space between the panes, the blind having slat tilt angle control means associated therewith; an aperture defined through one pane of glass providing access to the slat tilt angle control means of the blind; an adjusting device sealingly mounted about the aperture so that the tilt angle of the slats may be adjusted while maintaining thw window seal, the device comprising a plug including a threaded outer cylindrical surface extending outwardly through the aperture and having an annular flange portion engaging a surface of the pane of glass, the flange being sealed about the aperture, the plug defining a tubular portion being open at both ends thereof and extending inwardly from a planar front surface of said pulg, a flexible tube sealed about the tubular portion and extending therefrom into a sealing engagement with the slat tilt angle control means of the blind, a flexible cable being attached at one end to the tilt angle control means, said cable extending through the flexible tube and tubular portion so that the other end thereof may be manipulated to adjust the tilt angle of the slats, and a nut coacting with the threaded outer surface of the plug to provide a sealing engagement of the plug about the aperture.
Claim 3
Dependent Claim 24 words
A window as claimed in claim 1, further comprising a sealant material provided between the flange portion of the plug and the glass surface.
Claim 4
Dependent Claim 20 words
A window as claimed in claim 2, further comprising a sealant material provided between the nut and the glass surface.
Claim 5
Dependent Claim 13 words
A window as claimed in claim 1, wherein the flexible cable is metal.
Claim 6
Dependent Claim 31 words
A window as claimed in claim 1, further comprising means associated with the end of the flexible cable extending through the tubular portion of the plug for manipulation of the cable.
Claim 7
Dependent Claim 21 words
A window as claimed in claim 5, wherein the means associated with said cable end comprises a worm and gear mechanism.
Claim 8
Dependent Claim 34 words
A window as claimed in claim 6, wherein the flexible cable is provided with squared end portions adapted to be attachable to the slat tilt angle control means and the worm and gear mechanism.
Claim 9
Dependent Claim 61 words
A window as claimed in claim 7, wherein the worm and gear mechanism comprises a housing within which are positioned a worm gear and a worm coacting with the gear so that rotation of the worm causes rotation of the worm gear, and the worm gear defining an aperture extending centrally therethrough for receiving a squared end of the flexible cable.
Claim 10
Dependent Claim 46 words
A window as claimed in claim 3, further comprising a worm and gear mechanism coacting with an end of the flexible cable to provide manipulation thereof, said mechanism being attached to the plug by means of fasteners extending from the mechanism to engagement with said nut.
Claim 11
Dependent Claim 64 words
A window as claimed in claim 8, wherein the plug has a threaded outer surface, a first nut coacting with the plug to provide a sealing engagement of the plug about the aperture, a second nut coacting with the plug and having means therein for receiving fasteners extending from the worm and gear mechanism thereby providing means for attaching the mechanism to the plug.
Claim 12
Dependent Claim 31 words
A window as claimed in claim 4, wherein the flexible metal cable is capable of transmitting torque from one end to the other when bent at an angle of about 90°.
