Detailed Description

Technical Field

The present invention is related to a flexible cable canal that describes an integrated structure with an awning and which is used for transferring the energy necessary for lighting in the awning with illumination and being not required an additional cable carrying canal thanks to its novel physical structure.

Prior Art

In awnings having an illumination feature of the prior art and in some other applications requiring ligting and electrical energy; the cables carrying that energy are installed by using cable carrying canals over awnings. But cable canals are weaker to the outer space conditions after installation because they do not have a flexible structure or being difficult to install. During installation, the assembler should fix the cable canal onto the awning, then fix the necessary cables into the canal and finish the job with a cover that is designed specially for the canal itself. After the installation, the canal could be harmed by harsh environmental conditions or during usage of the awning and this can cause formation of unwanted views.

Furthermore the NYM or other type of insulated cables of the prior art, mostly could be wrapped easily thanks to their cylindrical shape but they cannot be installed onto an awning only by this state.

Objects and Short Description of the invention

An object of the invention is to put forward a flexible cable canal or guide structure which is integrated onto an awning as it is not required further cable canal or additional installation apparatus.

Another object of the invention is to produce a cable canal or guide especially in awnings with illumination that is resistant to outer space environmental conditions while during carrying the necessary electrical energy for lighting as putting an integrated structure but at the same time flexible in an extent of allowing to pass a cable within.

Short Description Of The Figures

In Figure 1 , as a close perspective view of the present invention is given that the canal is fixed onto the awning for cable in awnings of the present invention which have been passed a cable within, in Figure 2 a distant view of its integrated structure with the awning is seen. In Figure 3 another close perspective view of the canal of the present invention is given and in Figure 4 a perspective view from the bottom of the canal which a cable is passed therein and that is fixed onto the awning, is seen..

Deteailed Description of the invention

The present invention is related to a novel cable structure developed for illuminated awnings needed for outer space environments, which has both decorative and protection properties against outer environmental conditions. The canal (10), which its perspective view is given in figure 1 , thanks to its physical structure, has all positive properties of a prior art cable carrying canal and eliminates all its negative effects. The insulated cables or NYMs which are used in electrical installations in the prior art; generally have a structure including three electricity carrying wires as phase, neutral and the ground therein and at the outside a cylindrical outer cover which holds these three wires and their claddings together. Said insulated cables can only be used in awnings with illumination of the present invention generally with PVC cable carrying canals of the present time. But because of disadvantages described above, using said structre; on one hand increases the installation and maintenance costs, on the other hand decreases the reliability.

Cable carrying canals protect the cables, which are being installed therein and having already an insulation, from outer space conditions. But during this operation, they can be easily deformed when they confront outer space conditions or misusage circumstances.

As can be seen from figure 1 and 2, a canal structure (10) as a monolithic guide is put forward both that can be applicable onto an awning and which is not effected from outer space conditions. When base (10.4) of the canal (10) of the present invention is mounted, a little gap or cavity (10.6) is defined among the awning (12). Furthermore to adapt it onto the awning (12) easily and to settle thereon, there are some flanks (10.3) having some heights beginning from the base (10.4) to the side surfaces (10.2). Upper and side surfaces (10.1 , 10.2) are to establish the outer view of the awning and they can be of elliptical form or a shape having more corners or some other different geometrical structure.

As can be seen from figure 3 for upper and figure 4 for lower perspective views, the canal (10) carries the energy which is to be transferred by electrical cables (11 ), which are passed therethrough. The electricity cable (11) has a conductor wire (1 .1) inside and a dielectric cladding (1 .2) outside as being of prior art technique.

Outside of the electricity cable (11), which is passing through the canal (10) of the present invention, is made of a material being dielectric and resistant to external environmental conditions. As being in a NY cables having circular cross-section, it can both hold the energy carrying wires (11.1 ) together and can collect the properties of outer cladding and cable canal as a whole. Therefore an awning cable canal (10) having a guiding structure is put forward by the present invention so as to prevent from using a cable canal and its requirements such as labour costs and vulnerability to external environmental conditions.

Because of the canal (10) has a structure of both resistant and flexible, in case of the conductor wire (11.1) is damaged or should be changed, the old wire (11) could easily be extracted out and replaced with a new one by guiding the wire cavity. As can be seen from figure 3 and 4, the electricity wire (11) going through the canal (10) of the present invention, can be moved easily within the canal cavity (10.5). Said moving flexibility allows adding an electricity cable (11) or naked conductor wire (11.1) easily into the canal cavity (10.5) that is formed during production within the cable (10). Furthermore the canal cable (10) of the present invention having an enlarged fiat bottom surface (10.4) thanks to flanks (10.3) that it belongs to, therefore becomes easy to install and to serve for maintenance after installation.

Installing or sticking the canal (10) of the present invention onto the awning becomes very easy due to its flanks (10.3). While said flanks ( 0.3) are fixed onto the awning so as not to ieave a gap, a cavity (10.6) is formed between the canal base (10) and the awning to provide flexibility troughout the canal (10). Thanks to said cavity (10.6), some stresses, that could be applied from outside, are absorbed and some flexibility in accordance with the structure of a moving awning ( 2) is gained. Namely the canal (10) itself will not be effected negatively by some stresses and tensions that can be happened over the awning (12) and it does not obstruct the movements necessary for the awning (12). Furthermore owing to this flexibility gained during guiding the cable (11) into the canal (10), it becomes easy to install cables (11) more than one or to change the cables (11) after installation. Moreover the canal (10) provides insulation from the environment once more to the electricity cables ( 1) having outer insuiation cladding layer (11.2). The cable or cables (11) can move easily within the volume formed by the canal (10). Therefore, for instance, in an installation having three cables, thanks to the flexibilty defined by the present invention, extracting out a cable (11), which is damaged or necessary to be changed, from the canal (10) and installing a new one by guiding in place of it becomes very easy.
