Description
W. KAM PAS SHADE ROLLER May 26, 1931.
Filed April 4. 1930 'A Homey Patented May 26, 1931 UNITED STATES WILLIAM XAMPAS, OF D ES MOINES, IOWA SHADE ROLLER Application. fuea April 4,
This invention relates to a new and irnproved window shade roller of a longitudinally extensible all metal spring wound type.
In carrying the invention into practice, I
have involved and produced a roller construction which is characterized by novel details arranged in a practical manner to fulfill the requirements of a device of this class in a satisfactory manner, the structure being regarded as a distinct contribution to the art and susceptible of fulfilling the requirements of a device of this class in a more satisfactory manner.
The specific details and their relative arrangement and association will become more readily apparent from the following description and drawings. y
In the drawings l f Figure 1 is a view in section and elevation of the complete structure as developed in accordance with the present invention.
Figure 2 is an enlarged transverse cross section on the line 2-2 of Figure 1.
Figure 3 is an end View of the structure ob- 95 serving it in a direction from right to left in Figure 1.
Figure 4 is a fragmentary perspective view of a special shade clamp.
Figure 5 is a fragmentary perspective view of a portion of the retainer strip.
Figure 6 is. a sectional view of the especially constructed lianged cap.
The roller 7 is made up of two companion parts, namely a male tube 8 fitting telescopically into a female tube,"on the left hand end of the tube 8 there being a centralized pintle 10 fitting into a bearing hole in the complemental bracket 11. On the end of the female tube 9 is a concavo-convex cap 12 having a centralized shank 13 removably iitting into the notch in the other wall bracket 14 as seen in Figure 3. This cap has a flange 15.
VPivotally mounted on the bracket 14 is aV retaining pawl 16 whose bent free end eX- tends over and embraces the ange 15. This pawl is held down in frictionalengagement with the flange and cap through the medium of a coiled retention spring 17, one end being anchored on the pawl, and the other end fas- 13o. serial No. 441,621.
tened to the bracket 14 as seen clearlyin i Figure 3;
The letter A designates the internal coiled tensioning and return spring. This is of any suitable construction. Both of the tubular sections of the roller are formed with interfitting, inwardly pressed channelshaped keepers 18 as seen in Figure 2. This eXtensible keeper arrangement serves to accommodate the especially designed clamping device 19 for the shade 20. The clamp comprises a hooked retaining flange 21 which is pressed against the free end of the shade in the manner represented in Figure 2. In
addition there is a guard and fastening lip 22 which takes the position also represented in Figure 2. The numeral 28 designates a finger piece.
The numeral 24 represents ay longitudinally bowed compressing strip which is interposed between the keeper 18 and the back of the clamping device 19 as also seen in Figure 2. This serves to press the clamp outwardly against the converging walls of the channel-shaped keeper 18 to hold the clamp` frictionally in adjusted position.
The features to be noted in connection with this new arrangement are these. First, I call attention to the longitudinally extensible and adjustable construction of the roller 7 made up of the telescopically connected tubes 8 and 9 having the interfitting channel-shaped portions 18 defining an adjustable channel for accommodation of the especially designed shade clamp 19. The shade clamp itself is of a practical type for holding the shade in place.
It is bodily pressed outwardly into frictional binding contact with the upper and lower walls of the channel 18 through the medium of the spring strip 24. Then too,
, the all metal arrangement of the device is an evident feature, as well as the spring pressed retaining latch 16 cooperating with the especially designed concavo-conveX cap 12 on the right hand end of the roller construction.
It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invennfl tion after considering the description 1n coni nection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.
B/Iinor changes in shape, size, and rear- 5 rangement of details coming within the ield of invention claimed may be resorted to in actual practice if desired.
I claim: In a shade roller construction of the class described, a tubular roller provided with a longitudinal inwardly bent channel-shaped keeper the upper and lower walls of which are disposed in outwardly converging relationship, a shade, a clamping device for the upper end portion of said shade including a hooked retaining flange and a complemental securing lip, and a. flexible retention strip interposed between the web portion of the keeper and the back of said clamping device, said retention strip serving to force said clamping device outwardly into binding and retaining relationship with the upper and lower walls of the keeper in the manner dcscribed.
In testimony whereof I af'rix my signature.
VILLIAM KAMPAS.
