The upper end of the cable 57 passes beyond shaft 56 and extends through the slot 62 formed at least in the upper end of the support 55. It is attached to, for example, the bar 41 of web 29. It will be apparent that if, conveniently, three passes of cable 57 are disposed around the sheaves or pulleys mounted by shafts 56 and '8, block 59 will travel at only one-third the speed of web 29. This will be despite the fact that the end of the cable 57 attached to the free end of the awning material will move in unison with the latter. A greater or lesser number of passes may, of course, be employed.
However, with spring 60 involving a proper contractive force, it is apparent that it will constantly exert a pull on block 59, which, in turn, through cable 57, will be transmitted to web 29.
The latter will be retracted or permitted to project incident the operation of mechanism 22. As it projects, bar 41, under the pulling force exerted by cables 57, will move outwardly and downwardly. As it is retracted, a resistance will be imposed upon movement by the web 29. In the instance of the structure shown in Fig. 2, roller 25 will of course drive reels 45 through pulleys 50. Due to increasing effective diameter of the reels 45 as the cable 42 is wound there-around and the slippage capable of occurring at this point, complete compensation is achieved so that the material is maintained in taut condition. Under both conditions, that web will be maintained in rm sliding contact with the upper faces of the supporting members or channels. In all forms of construction, it will be apparent that the material of web 29 will be properly anchored against displacement `with respect to the channel members. However, it may, without diculty, slide longitudinally of those members as the operating mechanism is caused to function.
Thus, among others, the several objects of the invention as specifically aforenoted are achieved. Obviously, numerous changes in construction and rearrangements of the parts might be resorted to without departing from the spirit of the invention as deiined by the claims.
l. An awning structure including, in combination, a web of material, a channelled supporting member therefor, said web resting upon said member, means attached to said web and extending through the channel of said member to retain said web against withdrawal from said member, said web being movable longitudinally of said member, and manually adjustable means for tensioning said web in a transverse direction.
2. An awning structure including, in combination, a downwardly inclined channelled member formed with a slot in its upper surface, a web of material supportable in sliding contact with the upper surface of said member, Said web having an outer end, a cable within said member and extending through the yslot of the same, said cable being connected to the lower and outer end of said web, and means for moving said cable.
3. An awning structure including, in combination, a channeled member formed with a slot in its upper surface, a web of material supportable in sliding contact with the upper surface of said member, said web having an outer end, a cable within said member and extending through the slot of the same, said cable being connected to the end of said web, means for moving said cable, a flexible reinforcing strip disposed within said member,
6 means for connecting the material of said web to said strip and said connecting means extending through said slot to the exterior of said member.
4. In combination, a movably supported roll of awning material having an outer end, driving means for winding and unwinding said roll, a slotted guide and support extending away from said roll and in contact with the upper surface of which said material slides, means con nected to such material and extending through said slot to bear against another surface of said guide to movably retain said material against separation therefrom, and means connected to the outer end of such material to subject the latter to tension.
5. In combination, a movably supported roll of awning material having an outer end, driving means for Winding and unwinding said roll, a slotted'guide and support exten-ding away from said roll and in contact with the upper surface of which Said material slides, a. strip extending longitudinally of and within said guide, connecting means passing through said slot and attached to said strip whereby it is movably retained against separation from said guide, and means connected to the outer end of such material to subject the latter to tension.
6. In combination, a movably supported roll of awning material having an outer end, driving means for winding and unwinding said roll, a plurality of slotted guides and supports extending away from said roll and in contact with the upper surface of which said material slides, means connected to such material and extending through such slots to ride against another surface of said guide to movably retain said material against sep-aration therefrom, and means `for increasing and decreasing the width of the slot forming La part of at least one guide to subject the connecting means and said material to increasing and decreasing tension.
7. An awning structure including in combination a plurality of supports extending in a substantially horizontal plane and having channels with restricted entrance portions in their upper faces, a layer of material overlying said supports and carried thereby, means for shifting said material layer over said supports, retaining means riding within said supports, said material extending through the entrance portions thereof into the interior of said supports and means for connecting said material within said supports to said retaining means.
8. In an awning structure as specified in claim 7, and means associated with one of said supports for exerting a transverse strain on said material to tension the same.
9. In 'an awning structure as specified in claim 7, said material shifting means comprising elements extending within the channels of said supports and means connecting said elements to said material.
