Description

The present invention relates to a fully foldaway awning. More particularly, the present invention relates to a fully foldaway awning according to the preamble of claim 1.
Many types of awnings are known with different supporting, winding and extension means, hand- or motor driven.
The main drawback of all the types known of awning is that the valance, i.e. the strip of fabric which is the finishing terminal along the most external edge of the awning is not windable, remains always outside the headrail and is continuously subject to atmospheric agents. In such conditions, it is obvious that not much after the installation and the start of the use, evident differences appear between the awnings, which can be wound and protected in the inside of the headrails, and the corresponding valances, always exposed, which differences are due to colour decay, smog, powder, wear due to beating, and so on.
Such phenomena become obviously more and more marked as seasons pass and change.
To try to eliminate the above drawbacks, some producers supply awnings without valance. However, such solution is little agreeable and unsatisfactory for users.
Other drawbacks of the awnings of the known art are also to be found in hand or motor control systems, for the unwinding and the rewinding. In fact, many solutions are rather complicated and expensive and show special problems in the combinations with awnings oriented with marked inclinations.
Further drawbacks are caused by the internal configuration of headrails, where the sequence of windings and extensions of the awnings cause the latter to wear rather quickly especially in correspondence of the possible longitudinal sewings, and anyhow along the surface corresponding to the last winding turn on the drum.
Object of this invention is to eliminate said drawbacks.
According to the present invention, these and other objects - which will be more apparent thanks to the following description - are obtained according to the features of the characterising part of claim 1.
The fully foldaway awning of the present invention allows to achieve the following results:
The awning if fully foldable in the headrail and the valance is fully windable in the front transversal terminal; once the winding of the awning has ended, the transversal terminal wherein the windable valance is comprised, touches and closes the headrail containing the awning; the winding of the valance in the transversal terminal is realisable by hand by means of at least a side knob, or it is realisable automatically by means of gears coupled to the conventional extension and/or closing movements of articulated arms which control the opening or the winding of the awning, independently on such control being hand or motor-driven, with help manoeuvres by winches; the headrail comprises supporting end plates adjustable according to the inclination which one wants to impart to the extended awning; a holed support may be coupled to at least one of said plates, through which an end passes of the awning winding drum, for its direct connection with a rotation activation group, motor controlled with help manoeuvres, or hand controlled, which results to be correctly oriented vertically, independently on the inclined setting of the awning; inside the headrail a peripheral smooth, anti-abrasion shell is applicable, while along the transversal terminal elastic, half-annular pliers are located, co-axially coupled around the winding roller, having the function of regulating and guiding the valance during the winding/unwinding stages.
The advantages achieved by means of the present invention lay essentially in that, in closing conditions, both the awning, the related articulated arms and the valance are fully covered and protected from any external agent: the valance winding system may be independent and manual or automatic coupled with the opening and closing movement of the articulated arms of the awning, independently on the hand- or motor control of the awning; the protection systems of said parts, of movement and orientation are constituted of simple means, rational as concerns the structure and of easy and economic realisation. The fully foldaway awning of the present invention will be described with more details hereunder, with reference to the attached drawings which represent an embodiment expounded by way of non limiting example, wherein:

Figures 8 and 9 show perspective schematic sequential views of the system of automatic winding/unwinding of the awning
With reference to the figures, the fully foldaway awning of the present invention comprises an awning (1), a headrail (2) provided with a winding drum (3) and articulated arms (4) and a valance (5). Valance (5) is comprised in a front transversal terminal (6) equipped with a winding roller (7) for the awning and drive elastic clips (8) Terminal (6) engages with the front edge of awning (1) through a roping/raceway coupling (9). With like roping/raceway couplings (10) (11), awning (1) engages the back edge to its winding drum (3) and valance (5) engages the upper edge to its winding roller (7).
The inside of headrail (2) is covered by a continuous protecting shell (12) from plastic material or metal, such as, by way of non limiting example, PVC, chrome-plated steel and the like, which causes the inside winding housing of the awning to be smooth and uniform, preventing in this way the awning from getting dirty or wearing following the manoeuvres. The front terminal (6) comprises a longitudinal recess (13) closed at the top and open at the bottom, wherein the winding roller (7) of the valance is enclosed.
In said front terminal (6) semiannular elastic pliers (8) are located which, fixed along a groove (14), extend with their arms around the winding roller (7), forming an open circle whose internal diameter corresponds, at rest, to the diameter of roller (7) plus a fabric turn of the valance (5).
When awning (5) winds on roller (7), the arms of clips (8) open elastically due to the increased size of the wound fabric, and the internal walls of said arms exert on the fabric a pressure sufficient to obtain a correct winding adhering around said roller (7).
The pressure exercised by the arms of pliers (8) is especially useful during the contrary operation, i.e. when the valance (5) is unwound and goes down towards the outside. In fact, such pressure prevents the fabric from unwinding inside recess (13) and facilitates the regular and progressive unfolding of the fabric, without any hindrance.
In case of valances (5) having longitudinal sewings (46), the elastic clips (8) are positioned in correspondence of said sewings, except for those of side edges. If valances have no intermediate sewings, clips (8) are positioned at a uniform distance along the extension, edges being always excluded.
Winding and unwinding of valance (5) may be realised by a manual system comprising, at least on one of the ends of the transversal terminal (6) a knob (15) provided with a hub (16) which fits into an end of the winding roller (7). The rotation of roller (7) may also be automatic, according to the opening and winding movements of the awning (1). The automatic rotation of roller (7) takes place as follows: when awning (1) is closed and the opening movement starts, the profiles (19) and (20) of the two articulated arms (4), to which said awning is engaged along the external edge, shift from their parallel closing position and start articulating unthreading awning (1) from headrail (2).
To each lower profile (20) of the articulated arms (4) a supplementary lever (21) is engaged. At the end of said supplementary lever (21), a sliding block is hinged with or without wheels or rolls (22 DX and 22 SX) which can slide along grooves (23) obtained on the front transversal terminal (6). The end supports (35) of the same lower profiles (20) are tied to the same terminal (6).
During the opening, the sliding blocks (22 DX and 22 SX) slide along grooves (6), exercising a traction on ropes (24 DX, 24 SX) fixed to the same.
With specific reference to Figures 8 and 9, one of the ropes (24 DX) making part of the sliding block (22 DX) slides around a support with a central pulley (25), enters the through-holes of said sliding block (22 DX) and of stop (26 DX) of the transversal terminal (6), slides on a pulley of a support (27 DX) and fixes to the upper part of a pulley (28 DX) engaged at the right end of roller (7) for the winding of valance (5).
On the other side, the other rope (24 SX) making part of the rolling block (22 SX) enters the through-hole of stop (26 SX) of the transversal terminal (6), slides on a pulley of support (27 SX) and fixes to the lower part pulley (28 SX) engaged in the left end of the same winding roller (7).
During the opening of the awning, lever (21 DX) creates a traction on rope (24 DX) wound on pulley (28 DX); this one causes roller (7) to rotate and the valance unwinds. At the same time, to the left side rope (24 SX) winds on pulley (28 SX) so that, when awning (5) is enclosed, lever (21 SX) exercises a traction on its rope (24 SX), which causes pulley (28 SX) to rotate in the contrary direction with regard to the preceding one, with ensuing winding of the valance. In the same way, to the left side rope (24 SX) re-winds on pulley (28 SX) and the system is already ready for a subsequent opening of the valance at the same time as the opening of the awning.
It should be noted that the system of winding/unwinding of the valance takes place at the same time as the corresponding operation exercised on the awning, independently on the hand-or motor system adopted for the same awning.
Figures 5 and 6 show the side supports (29) which, associated to counter-plates (30) may be adapted for both horizontal wall-applications and vertical ceiling-applications. In any case, plates (3) tied to the end of headrail (2) are coupled to and engaged with supports (29). The coupling between supports (29) and plates (31) allows the installation of the awning with any inclined orientation.
At least one of plates (31) comprises a central through-hole (32), aligneable to a corresponding hole (33) of at least one of said supports (29) through which an end of said winding drum (3) of awning (1) inserts, to facilitate its connection with any hand- or motor movement means, with conventional help manoeuvre, comprised in a casing (34) aligneable always by means of vertical manoeuvres, independently on the more or less inclined orientation of plates (3), and therefore of awning (1)
In conditions of full closing or total winding of awning (1) in headrail (2) and of valance (5) in the front transversal terminal (6) the upper-back part (36) of the latter engages with and superpose on the upper-front end (37) of said headrail (2), forming a full, single and sequential protection covering of the whole.
In an application suggested by way of non limiting example, the inclined coupling between plates (31) and supports (29) is realised by means of side sectors (38) that engage their toothed ends (39) in as many complementary housings (40) obtained along the peripheral edges of supports (29).
Sectors (38) are kept engaged with housings (40) by means of back friction couplings between the ray-like surfaces (42) of as many buffers, locked by pressure screws (43). After the setting of the maximum desired inclined position, and before fully locking screws (43) by means of screw regulators (44), it is possible to carry out an exact micrometric positioning by causing said ray-like surfaces (41, 42) to slide relatively to one another.
Having established the desired position, said surfaces engage with one another, tightly locking screws (43), and screw-regulators (44) are locked by means of dowels (45).
Even though the present invention has been described hereabove with reference to a possible embodiment of the same, various changes and modifications may be made by those skilled in the art, in view of the above description.
Therefore, the present invention intends to comprise all of the changes and modifications falling within the scope of the appended claims.
