Definitions

the present invention concerns a covering apparatus and a guide element for a solar covering apparatus, such as a pergola or other outdoor structure, with a covering and protection function, possibly also lateral, intended for civil use mainly supplementary to residential areas, but also for commercial, exhibition or public use.
the pergola is generally provided with an upper structure with which the covering elements cooperate, which generally create a desired condition of direct or indirect radiation, i.e., of passage of air, light and water, in the area below the upper structure.
the guide element is applied to maintain the covering elements under desired operating conditions, both under static operating conditions and operating conditions of reciprocal movement.
Covering apparatuses of the pergola type typically provided with a lower support structure, formed by a plurality of vertical structural support elements, also called uprights, able to support, at a certain height, from the floor or from the ground, an upper structure having the shape of a quadrangular frame are known.
This upper structure is normally composed of support elements, typically horizontal or moderately inclined in the order of 5°-20°, with respect to the floor, also called carriers.
the aforementioned frame may lack a side, so that the upper support structure is substantially in the shape of a U.
the upper support structure may also be partly attached to fixed support elements, for example to one or more walls of a building.
the upper structure is operatively associated to upper covering elements, or slats, advantageously movable between them to define at least a closing operating condition which corresponds to a covering condition, in which they are substantially adjacent to each other and define a real "roof' of the structure, and a plurality of opening conditions, which correspond to respective uncovering conditions, in which they are spaced apart from each other to define relative spaces, more or less wide, of passage of light and/or air or other atmospheric agents.
This type of solutions advantageously provide cam guides on which correlated cam followers will slide and which are provided on the second group of slats, i.e., the one that will be higher than the floor, in a mounted condition.
these cam guides are advantageously open upwards, so that said second group can be rested with its cam followers on the relative cam guides, avoiding lateral slipping of the slats, screwing and/or other operations that, at height, may involve operational delays and risk for the operators.
this simplified solution may be deficient in the event that the second group of slats receives some stress from below, for example because of direct or indirect wind, i.e., due to an accidental impact or other unforeseen factors such as branches, leaves or other objects fallen by gravity on the cam guides.
one purpose of the present invention is to realize a guide element capable, on the one hand, of allowing the normal simplified mounting of the cam followers in the cam guides and, on the other hand, of substantially preventing the cam followers from accidentally exiting from the cam guides themselves.
Another purpose of the present invention is to develop a guide element that is simple and economical to realize, and that does not modify the aesthetic impact of the covering apparatus.
the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
a guide element according to the invention is applied to a covering apparatus of the type having at least an upper structure, provided with a plurality of covering elements, such as for example metal slats, which are reciprocally movable between them to define at least a covering operating condition, in which they substantially prevent the passage of light and/or air through the upper structure, and a plurality of opening conditions, in which they define desired direct or indirect passages of light and/or air.
a covering apparatus of the type having at least an upper structure, provided with a plurality of covering elements, such as for example metal slats, which are reciprocally movable between them to define at least a covering operating condition, in which they substantially prevent the passage of light and/or air through the upper structure, and a plurality of opening conditions, in which they define desired direct or indirect passages of light and/or air.
Reciprocal movement means that each covering element assumes different positions with respect to the others, both individually and in groups, as well as that this element can remain stationary and the others move reciprocally with respect to it, in order to define the aforementioned opening conditions or the covering condition.
This movement is normally guided by at least one cam guide, advantageously open upwards, and by at least one sliding element, the latter associated to at least a part of the covering elements and sliding along the cam guide.
the guide element comprises at least one containing wall, which is operatively counterposed to the cam guide, with respect to the sliding element.
the sliding element is in an intermediate housing condition and contained between the cam guide, below, and the containing wall, above.
This housing condition allows the sliding element to maintain a correct and effective travel along the cam guide and, at the same time, is contained above by the containing wall.
This advantage of the present invention allows to guarantee the effective cooperation between the sliding element and the cam guide, even in circumstances in which the covering element is bounced by the action of the wind, i.e., by an accidental impact or by other external factors.
the containing wall being counterposed to the cam guide, defines a protection for the guide itself, limiting to a minimum the possibility that leaves or other objects may settle by gravity on this guide, which may cause the sliding element to bounce, or even deviate.
the containing wall has a longitudinal shaping coordinated to the shaping of the cam guide.
This advantageous solution allows to guarantee a substantial uniformity of containment intervention in case of accidental lifting and, at the same time, to limit to a minimum possible vibrations and noise that may occur.
the containing wall has a longitudinal shaping coordinated both to the shaping of the first guide segment and to the shaping of the second guide segment.
the containing wall follows in a coordinated manner the course of the cam guide, so as to guarantee its effective containment action substantially in whatever position the sliding element is located and, therefore, substantially under any operating condition of reciprocal positioning of the covering elements.
the guide element is provided with a support wall, which is inclined with respect to the containing wall, and with means for coupling with the cam guide, of the selectively removable type.
This aspect of the present invention allows, on the one hand, to selectively couple the guide element to the covering apparatus and, on the other hand, defines a structural impediment to the accidental exit of the sliding element from the cam guide, along a direction inclined with respect to the one managed by the containing wall.
these features allow the guide element to be selectively removed and applied, for example during the steps of mounting the covering elements, in order to reduce the times and costs of intervention for mounting or replacing the covering elements, as well as to facilitate the same mounting operations for the benefit of the use and safety of operators.
the containing wall may comprise at least a through aperture, which allows the insertion of the sliding element.
a rest wall is provided, which is placed operatively side by side with the cam guide and substantially counterposed to the containing wall.
a sliding seating is defined between the containing wall, the support wall and the rest wall, i.e., according to variants only between two of the three walls, within which the sliding element at least partially slides.
the coupling means comprise at least a coupling wall, selectively associable with the guide profile, and at least a coupling member provided at least partly on the coupling wall and at least partly on the guide profile.
the coupling member comprises at least a male interlocking element, provided on the coupling wall and at least a female interlocking element, provided on the guide profile.
this type of male-female coupling can be provided with a coupling system with screw and threaded hole, i.e., with bolt, or with dowel and slot, i.e., with elastic clips, as well as by shaped coupling between the coupling wall and the guide profile, i.e., other removable coupling solutions of substantially known type.
the attached figures refer to a covering apparatus and a guide element 10 applied to a covering apparatus, in this case, an outdoor pergola 100.
the pergola 100 typically comprises four vertical uprights 111 conformed to maintain an upper frame 112 under a desired lifting condition, the latter substantially formed by four horizontal carriers 113, possibly provided with relative gutters, not illustrated in the drawings.
Said frame 112 is conformed to support a plurality of covering slats 114 and 115, arranged substantially parallel to each other, so as to occupy the internal space thereof.
the slats indicated with reference numeral 114 are fixed with respect to the upper frame 112, while the slats indicated with reference numeral 115 are movable with respect to the slats 114.
each slat 114 is attached longitudinally to the opposite carriers 113 of the frame 112, while each slat 115 is attached longitudinally to opposite movement profiles 116 (only schematized in the figures), and which are associated sliding and substantially parallel with respect to the aforementioned carriers 113.
the movement profiles 116 are connected to an actuator (not illustrated) that causes their selective movement in one direction or the other, with respect to the carriers 113 to which they are associated.
a guide profile 124 attached substantially parallel to the corresponding carrier 113, is provided.
At least one cam guide 125 which comprises, in this case, a substantially V-shaped path defined by two first segments 128 with substantially linear course, and two second segments 129, inclined downwards with respect to the first segments 128, in continuity with each other, is obtained on one edge of said guide profile 124.
the movement profile 116 is also associated with relative cam follower elements 126 which cooperate with the cam guides 125 to cause the reciprocal positioning between the slats 114 and 115 in the envisaged operating conditions.
each cam follower element 126 comprises a support and a wheel, which translates along the first 128 and second 129 segments of the corresponding cam guide 125.
a guide element 10 generally comprises a containing wall 11, a support wall 12, a rest wall 13 and a coupling wall 14.
the guide element 10 is made by moulding plastic material, but it is not excluded that it can be made of metallic material, both by plastic deformation and by chip removal, i.e., to provide that its walls 11, 12, 13 and 14 can be made individually and coupled together in an integral manner, for example by welding, i.e., removable, for example by screwing, interlocking or otherwise.
the containing wall 11 has a course correlated to the shaping of the cam guide 125, as defined by the V-shaped combination of the first segments 128 and of the second segments 129.
the containing wall 11 is substantially counterposed to the cam guide 125, with respect to the position of the cam follower element 126, so as to contain, with a desired tolerance, any detachments of the latter from the cam guide 125 itself, particularly upwards.
the support wall 12 is obtained substantially orthogonal to the containing wall 11 and defines a substantial structural impediment to the accidental exit of the sliding element 126 from the cam guide 125, along a lateral direction. Furthermore, the support wall 12 defines a connection between the containing wall 11 and the rest wall 13.
the latter is obtained counterposed to the containing wall 11, so as to be placed operatively side by side with the cam guide 125.
This conformation connected between the containing wall 11, the support wall 12 and the rest wall 13, defines a sliding seating 15, inside which at least an end element of the wheel of the cam follower element 126 slides.
this configuration allows to keep the cam follower element 126 contained at least between the containing wall 11 and the support wall 12, during the steps of travel of the cam guide 125 and, therefore, to guarantee a correct movement of the slats 115, with respect to the slats 114, regardless of external accidental actions such as wind, impacts or other.
the coupling wall 14 extends, in this case, below the rest wall 13 so as to offer its widest surface to the guide profile 124. In fact, the coupling wall 14 is operatively in contact with the guide profile 124.
Two coupling screws 16 are provided on the coupling wall 14, which are screwed into two corresponding coupling holes 17, the latter obtained in coordination on the guide profile 124.
the coupling wall 14 is coupled to the guide profile 124 and then the guide element 10 to the pergola 100, see for example Fig. 10 .
the entire guide element 10 is elongated with respect to the solution described so far and illustrated so as to cover the entire operating travel "S" of the cam follower element 126.
the covering wall 11, the support wall 12, and the rest wall 13 cover the entire distance that can be travelled by the cam follower element 126, guaranteeing its containment and the correct cooperation with the cam guide 125, substantially under all possible operating conditions.
an aperture 18 can be provided, by means of which an insertion from above of the cam follower element 126, with relative movement profile 116 and covering slats 115, is allowed or favoured.
the covering wall 11 is conformed with a shaping similar to the cam guide 125 defined by the three guide segments 128, 129 and 133.
the covering wall 11 is conformed in coordination with the cam guide 125, even under conditions in which the three guide segments 128, 129 and 133, individually or in free combination with each other, have a curvilinear conformation (regular or irregular).
