Abstract
A device for the driven winding and unwinding of a cloth (10) comprising: a roller (11) for winding up the cloth (10); a hollow rigid member (21) secured to the free edge of the cloth; a return cable; two spools for winding the return cable (19); two return rollers (16, 18) for the return cable (19) and two guides (14, 15) for the rigid member (21) supporting the cable return rollers and receiving the rising and lowering lengths of the return cable, wherein the whole system is also maintained in tension by a spring (20) interposed in the return cable and placed within the hollow member (21).
Description
- This invention refers to a device intended to be used for the controlled winding and unwinding of a cloth comprising: a roller for winding up the cloth; a hollow rigid member secured to the free edge of the cloth; a return cable; two spools for winding the return cable; two return rollers for the return cable and two guides for the rigid member supporting the cable return rollers and receiving the rising and lowering lengths of the return cable, wherein the whole system is also maintained in tension by a spring interposed in the return cable and placed within the hollow member.
- In the field of awnings, window shades, mosquito-nets and the like it is important that the cloth forming the awning, the window shade or the mosquito-net moves smoothly and without blocking.
- While a smooth movement can be easily obtained in case of cloths of reduced size or of cloths that are rarely operated, the same is not true in case of cloths of medium or big size or of cloths that are rarely unwound and subsequently rewound.
- Various proposals have been made to solve this problem using return springs and complicated driving systems, but they are often complex and costly and their operation is not always satisfying.
- This invention is intended to provide a simple and effective device which can be easily used without blocking also with cloths of big size such as awnings for terraces, gardens and the like.
- The invention will be now described as an example in an embodiment thereof referring to a window shade.
- In the drawings:
- Figure 1 is a rather diagrammatic perspective view of the device which parts omited or partially removed, showing the cloth in the lowered position; and,
- Figure 2 is a similar view showing the cloth in the rising position.
- The device of the invention substantially comprises: a moving
cloth 10; a roller 11 for winding upcloth 10; twospools side guides return rollers return cable 19 having aspring 20 placed at the half of its length; and, ahollow member 21 secured to thefree edge 22 of cloth 11 having theother edge 23 normally secured to roller 11. -
Guide 14 has alongitudinal slot 24 formed on itsface 25 and furthermore supportsreturn roller 16 at its base andspool 12 at its top by means of asupport 26. -
Guide 15 has aslot 27 formed on itsface 28 and supportsreturn roller 18 andspool 13 by means of asupport 26A. - The ends of
cable 19 are secured tospools side guide 14,hollow member 21 andside guide 15. -
Hollow member 21 is provided with twoend tabs 29 and 39 which are received withinslots cloth 10.Tabs cable 19. -
Spring 20 is interposed in the length ofcable 19 received withinhollow member 21 maintaining the continuity thereof and keeping the cable in tension in any position ofcloth 10. - In
use cable 10,which is wound onspools cloth 10 on roller 11, will automatically wind on the spools when the cloth is lowered, while unwinding of the cable will allow the cloth to rise and consequently wind on roller 11. - In an
alternative embodiment spring 20 can be omitted andcable 19 can be made of a suitable elastic material to be maintained in tension. - Furthermore, the cable can be replaced by equivalent members, such as strips, bands, belts and the like.
