SHADE-OPERATING DEVICE.
Application led October 15, 1921. Serial No. 507,951.
To all whom t may concern:
Be it known that I, CHARLES LENARDIC, a
citizen of Jugo-Slavia, residing at Cleve-` land, inthe county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Shade-Operating Devices, of which the following is a specification.
This invention relates to certain new and useful improvements in shade operating devices and has particular reference to the arrangement of pull cords associated with a shade roller for raising and lowering the shade in the absence of springs contained in the usual tensioned roller.
-A further object of the invention has particular reference to the formation of the bearing ends of the shade roller, the same being polygonal in cross section and engaged by a spring arm for holding the shade roller in adjusted positions when the saine 1s operated by pull cords.
With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described shown in the accompanying drawing and claimed.
In the drawing, wherein like reference characters designate corresponding parts throughout the several views,
Figure l is a fragmentary front elevational view of a window frame equipped with the present type of shade operating device, l
Figure 2 is a detail cross sectional view of a portion of the roller showing one of the mounting brackets and spring arm carried thereby for engaging the polygonal end of the roller,
Figure 3 is a detail fragmentary longitudinal sectional view of one end of the shade roller showing the manner of mounting the same and the pull cord associated therewith,
Figure 4 is an end elevational view of the roller showing the polygonal mounting, and
Figure 5 is a perspective view of one of the mounting brackets.
Referring more in detail to the accompanying drawing there is illustrated a window shade operating device supported within a window frame 1, brackets for supporting the shade roller including base plates 2 having right angularly extending and outwardly directed side plates 3 provided with openings 4 for the reception ofsuitable fastening-devices for securing the brackets to the adjacent sides of the window frame as shown in Fig. 1. The side plate 3 of one of the brackets is provided with a bearing opening 5 for rotatably supporting one end of the shade roller while the side plate of the other bracket has an edge opening angle slot 6 for removably receiving the other bearing end of the shade roller.
The shade roller embodies a stick 7 shown more clearly in Fig. 3 having each end'thereof reduced in cross section to provide an annular channel guide 8 and an outwardly directed shoulder 9 while the terminal ends of the stick outwardly of the channel portions are further reduced as shown in Figs. 3 and 4 and formed with a polygonal configura tion 10, the same being triangular as illustrated. An axial pin 11 inserted in the opposite ends of the roller stick slightly projects therefrom for reception in the bearings of the bracket plates 3.
A spring arm 12 secured at its lower end as at 13 to the base plate 2 of the bracket has the upper free end thereof bent outwardly and spaced from the base wall, the same being normally positioned beneath the bearing points 5 and 6 for the ends of the roller stick. When the roller is positioned in the brackets the springs 12 engage the flat faces upon the polygonal ends thereof to hold the shade roller against movement. A shade 14 suitably secured vto the roller stick 7 and an operating cord 15 is secured to each reduced portion 8 of the roller stick, the same being wound thereon in opposite directions so that by pulling upon the desired cord, the shade 14 may be raised and lowered. v The springs 12 engaging the polygonal ends of the roller stick will hold the shade in adjusted position, the cords raising and lowering the shade to the desired height and rotating the roller stick against the tension of the springs 12. It is to be understood that the terminal ends 10 of the stick may be of any desired configuration, the same being triangular as illustrated, but the ends, in cross section may be rectangular or of any polygonal formation. It will, therefore be seen that a shade roller capable of various adjustments in the absence of the usual roller' spring is provided, the shade roller being positively held in its adjusted positions against accidental movement by the springs 12 engaging the thereof.
What is claimed as new is z- 1. iA window shade I operating device `com- 1 prising a roller stick, awshadeweund "thereon, pull cords Woundupon the ends-ofthe stick 1n opposite directlons, pol g'onal'bearrotatably supporting 5the stick, andwmeans carried by each bracket engaging the polygonal ends for holding the stick Ainadjnsted positions.
