Definitions

  • the present invention concerns a mobile covering element for a covering apparatus, which can be preferably, but not limited to, an adjustable sunshade, even of a large size, in the range of several meters on each side.
  • the covering element has an oblong shape and is mobile between an operative, or covering, position, in which it is parallel to a covering plane, and an inactive, or open, position, in which it is inclined with respect to the covering plane, and vice versa.
  • the covering element together with other covering elements identical to and coplanar with it, produces an impermeable cover of a zone below, so that the latter is protected both from atmospheric agents, such as rain, snow, or hail, and also from other objects, such as branches, leaves, debris, or other, which might possibly fall from above.
  • the inactive position all the covering elements are reciprocally inclined and allow accessibility from above to the zone below, by any element or object whatsoever, including the sun’s rays.
  • adjustable sunshades which use oblong covering elements and have the function of protecting, selectively and even only temporarily, a zone below, both from the sun’s rays and also from atmospheric agents, such as rain, snow, or hail, and also from other objects that can fall from above.
  • covering elements for covering apparatuses which, although all are oblong, that is, with a length much larger than the width and height, or overall thickness, have the most diverse shapes, and are aesthetically similar to a blade, a fin, or a slat, therefore they are usually equally indicated with one or more of these terms.
  • One of the disadvantages of the known covering elements is that they are subject to a relative longitudinal flexion due to their own weight.
  • the amplitude of this flexion is directly proportional to the length of the covering element.
  • this flexion increases when there are atmospheric precipitations such as rain, snow, or hail, particularly when these are of considerable intensity, compromising the structural resistance of the covering elements or, at least, causing undesired stagnation of water, in the form of puddles, more or less large, which are not managed optimally by the normal water discharge systems.
  • This disadvantage entails both an increase in the power required of the movement members of the covering elements, and also the undesired discharge of water into the zone below.
  • Covering elements with a curved conformation are also known, which guarantee a greater resistance to flexion.
  • This latter type of covering elements have the disadvantage of having high production costs, since the elements themselves have to be subjected to calendering, or to other complex and expensive workings, in order to obtain the desired arched shape and, moreover, their final conformation is often unaesthetic and not appreciated by customers and end users, particularly when the covering elements are in their covering position, or in the intermediate positions between the open and covering positions. Furthermore, these do not guarantee an optimal passage of light and air through the covering apparatus, when this is desired.
  • a first known type of covering apparatus comprises a plurality of oblong covering elements, parallel to each other and pivoted at their ends on two support elements of a support structure, opposite and perpendicular to the covering elements.
  • the covering elements can rotate on their longitudinal axes of rotation in order to assume both a covering position, in which they are coplanar with a covering plane and protect the zone below, and also an inclined, or open, position, in which the covering elements are inclined by many degrees, for example up to 140° and more, with respect to the covering plane, thus allowing the sun’s rays and atmospheric agents to pass between the covering elements and reach the zone below.
  • An example of the first type of covering apparatus as above is described in the Italian patent IT-B-1.415.149, issued to the Applicant on 09.04.2015.
  • a second known type of covering apparatus comprises a plurality of oblong covering elements, parallel to each other and connected with their ends to an actuation mechanism, for example of the pantograph type, in turn slidably supported on two support elements of a support structure, opposite and perpendicular to the covering elements.
  • the covering elements commanded by the actuation mechanism, can assume both a covering position, in which they are coplanar with a covering plane and protect the zone below, and also an inactive position, in which they are inclined by many degrees, for example up to 90°, with respect to the covering plane and packed toward a transverse element of the support structure, so as to allow the sun’s rays and atmospheric agents to reach the part of the zone below left uncovered.
  • the upper support structure has the shape of a rectangular frame, and is configured to be positioned at a determinate height, for example a few meters, from the floor, or from the ground. In some cases, the frame can be missing one side, so that the upper support structure substantially has the shape of a U.
  • the upper support structure comprises at least three components, two of which are parallel to each other and perpendicular to the covering elements, and act as a support for the latter, while a third component, perpendicular to the first two, acts as a connection element between the first two, and is usually also used to house the motor members for moving the covering elements.
  • the upper support structure can be supported by supporting vertical uprights, so that the corresponding covering apparatus is aesthetically similar to a pergola, or it can be attached in any suitable way whatsoever to fixed support elements, for example to one or more lateral walls.
  • each individual oblong covering element usually comprises a central body, having a length in the range of a few meters, for example from 2 m to 6 m, a width in the range of a few decimeters, for example from 0.1 m to 0.3 m, and a height in the range of a few centimeters, for example from 0.01 m to 0.04 m, and provided with sealing means positioned along one or both of its longitudinal flanks, that is, along the longer sides, in order to guarantee impermeability when the same covering elements are in their covering position.
  • Covering elements are also known that can be oriented, each provided with an end compartment disposed in correspondence with one of the longitudinal flanks and conformed so as to collect the fluids that deposit freely on the upper surface of the covering elements themselves, after atmospheric precipitations and other events.
  • each oblong covering element is to allow water, both rain water and also of other types, for example voluntarily or accidentally poured from above onto the covering apparatus, to flow freely and without obstacles toward collection channels, or conduits, when the covering elements of the covering apparatus are in an operative, or covering, position, in order to then be conveyed to suitable discharge means.
  • covering apparatuses which, in correspondence with their upper support structure, are provided in the internal perimeter with a plurality of channels, sometimes called“eaves gutters” by those skilled in the art, which are disposed, usually on each side, below the lateral edges of the oblong covering elements, in order to collect the abundant water that flows onto the latter, as in the case of intense and copious precipitations, which are by the way increasingly abundant and with significant volumes per hour, per square meter, as in the case of heavy downpours, or thunderstorms.
  • channels sometimes called“eaves gutters gutters” by those skilled in the art
  • the disposal of the water has to take place without it falling, even in minimum quantities, into the zone below, even when the covering elements are moved in order to be taken from their covering position to their inactive, or open, position, for example at the end of the atmospheric precipitation.
  • One purpose of the present invention is to provide a mobile covering element for a covering apparatus, preferably an adjustable sunshade, which can easily be moved between a covering position, in which the mobile covering element itself is coplanar with, or parallel to, a determinate covering plane, preferably horizontal, and an open position, in which it is inclined by several degrees with respect to the covering plane as above and preferably packed toward a rear edge of the covering apparatus, and vice versa, and wherein, in the covering position as above, it guarantees, in association with other identical covering elements temporarily coupled with it, above all a perfect seal, or impermeability from above, even when it is subject to high loads located on top of it, which could deform it, for example bend it downward in its central part.
  • Another purpose of the present invention is to provide a mobile covering element for a covering apparatus, preferably an adjustable sunshade, which in the covering position as above only has one substantially flat surface, so that, in association with other covering elements identical to it and temporarily coupled with it, it defines a single flat, or differently shaped, surface substantially without irregularities of the entire covering apparatus, as if it were a flat, or shaped, ceiling of a room.
  • Another purpose of the present invention is to provide a mobile covering element for a covering apparatus, preferably an adjustable sunshade, which, while maintaining the required characteristics highlighted above, is relatively light in relation to its size, simple to produce and install, and has low production costs.
  • 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 mobile covering element for a covering apparatus preferably a an adjustable sunshade, comprises a main body with an oblong development, having a longitudinal axis, a first lateral edge, a second lateral edge opposite the first lateral edge, a first longitudinal flank, a second longitudinal flank opposite the first longitudinal flank, a lower wall having a lower surface disposed, in a covering position of the mobile covering element, on a covering plane, parallel to or passing through the longitudinal axis, and an upper wall disposed substantially horizontal in the covering position.
  • the mobile covering element as above also comprises conveying means configured to facilitate the outflow toward the lateral edges of what can possibly be deposited on the upper wall, in particular water, when the mobile covering element is in the covering position.
  • At least one first barrier is present on the mobile covering element, which prevents above all the water from going over the longitudinal flanks of the mobile covering element, when the same mobile covering element is in the covering position as above, spilling out into the zone below.
  • the mobile covering element also comprises a longitudinal containing compartment, disposed in correspondence with the first longitudinal flank and having an upper longitudinal aperture; in this case, advantageously, the conveying means as above comprise a first longitudinal wall disposed on the upper wall as above, in correspondence with the first longitudinal flank and before the upper longitudinal aperture of the longitudinal containing compartment as above.
  • the first longitudinal wall extends perpendicularly to the upper wall from the first lateral edge to the second lateral edge, and has the shape of a longitudinal ridge having the upper end at a determinate first height, preferably comprised between about 3 mm and about 6 mm from the upper wall.
  • the conveying means comprise a second longitudinal wall disposed on the upper wall in an intermediate position between the first longitudinal flank and the second longitudinal flank.
  • the second longitudinal wall extends perpendicularly to the upper wall from the first lateral edge to the second lateral edge and has its upper end at a determinate second height, preferably comprised between about 3 mm and about 6 mm from the upper wall.
  • the mobile covering element also comprises a longitudinal lateral appendix, disposed in correspondence with the second longitudinal flank, outside and in continuation of the main body, and the conveying means comprise an internal lateral wall of the longitudinal lateral appendix as above, which rises from the upper wall in correspondence with the second longitudinal flank, so that the upper wall, the first longitudinal wall, the second longitudinal wall and the internal lateral wall together form two upper longitudinal compartment, which facilitate the outflow toward the lateral edges and prevent the formation of a single pool of water at the center of the upper wall when the mobile covering element is in the covering position.
  • the water is evenly deposited and distributed in both the upper longitudinal compartments as above, reducing the load applied and, in any case, distributing the latter in the longitudinal direction of the mobile covering element itself. Therefore, on the one hand, the impact of the weight of the water on the flexion effect is reduced and, on the other hand, the autonomous discharge of the water toward the lateral edges, and hence into the discharge systems normally provided in the covering apparatus is facilitated, reducing to a minimum the risk of spilling water into the zone below, particularly during the first steps of opening the mobile covering element, which can occur, for example, by tilting the latter with respect to the longitudinal axis.
  • the longitudinal lateral appendix is positioned at least partly, preferably wholly, above the bulk of the main body.
  • the longitudinal containing compartment is substantially defined by the first longitudinal flank, by a terminal part of the first lower wall which extends outward beyond the first longitudinal flank, and by a lateral wall, which together with the latter defines the upper longitudinal aperture.
  • the lateral wall of the longitudinal containing compartment has in its upper part a first longitudinal protuberance, facing the longitudinal containing compartment and provided, in its upper part, with a first longitudinal seating, in which a first packing is disposed, which preferably extends for the entire length of the main body.
  • the mobile covering element also comprises a second longitudinal protuberance integral with the first longitudinal flank, facing the longitudinal containing compartment and provided, in its upper part, with a second longitudinal seating, in which a second packing is disposed, which also preferably extends for the entire length of the main body.
  • the second longitudinal seating and the first longitudinal wall define a longitudinal cavity between them; moreover, the longitudinal lateral appendix comprises a first lower protuberance and a second lower protuberance which define a longitudinal recess; additionally, the first lower protuberance and the second lower protuberance are configured to act as drip-guard elements, cooperating with the longitudinal cavity and, respectively, with the upper longitudinal aperture of another mobile covering element identical and adjacent thereto, of the covering apparatus, when the mobile covering elements are in the covering position.

  • the transmission belts 65 are connected to the mobile covering element 10 furthest away from the rear longitudinal beam 54 itself.
  • connection lever 61 apart from the end ones, which are reduced by half, is connected at the lower part to the first pin 32 of a mobile covering element 10, in an intermediate zone to the second pin 37 of a mobile covering element 10 adjacent to the first, and at the upper part to the third pin 48 of another mobile covering element 10 adjacent to the second.
  • Rotatable casters 66 slidable on guides of the lateral crosspieces 51 and 52, are associated on both sides with the first pins 32 of the mobile covering elements 10, in order to reduce to the minimum the friction during the movements of the latter between their inactive and covering positions.
  • the functioning of the covering apparatus 11 which uses the mobile covering elements 10 according to the present invention is very simple and substantially of the known type. In fact, by commanding the electric motor 63 all the mobile covering elements 10 are displaced between their inactive and covering positions.
  • each mobile covering element 10 in the inactive position the set of packed mobile covering elements 10 (figs from 1 to 4 and from 11 to 13), thanks also to the partial overlap of each longitudinal lateral appendix 38 with the main body 12 of an adjacent mobile covering element 10, occupies a very small space, in the range of about 20 mm for each element, that is, substantially half of the bulk with respect to the solutions of the state of the art, to the benefit of the extension of the area open to the sky in the inactive position, with the same covering surface.
  • each mobile covering element 10 covers, completely and in a perfectly hermetic manner, both the upper longitudinal aperture 26 of the longitudinal containing compartment 20, and also the first lateral flank 17 of an adjacent mobile covering element 10.
  • the water that falls from above is naturally conveyed toward the lateral edges 13 and 14 (fig. 4) and from there it falls into the channels 56 and 57 below.
  • the same water encounters two vertical barriers, consisting of the second reinforcement rib 35 (fig. 10), for the water that falls between the latter and the longitudinal lateral appendix 38, and the longitudinal ridge 29, for the water that falls between the latter and the second reinforcement rib 35.
  • the same water thanks also to the presence of the two packings 24 and 28 and to the lower protuberances 43 and 44, therefore cannot fall into the zone underneath the covering apparatus 11.
  • any water left on the upper wall 16 of each mobile covering element 10 would not fall below, but would be conveyed toward its lateral edges 13 and 14 (fig. 4) and the longitudinal containing compartment 20 (figs. 14, 15 and 16).
  • another advantage of the present invention is that, in the covering position, the set of the mobile covering elements 10 coplanar with each other (figs. 3, 4, 13, 14 and 15) guarantee a perfect, or almost perfect, flatness and a lower surface that is flat, or shaped differently, and substantially without a break in continuity, apart from the thin grooves between one mobile covering element 10 and the adjacent ones.
  • the set of mobile covering elements 10 has a much lower weight than those of the state of the art, with the same flexural inertia and covering surface, so that there are reduced production costs and the possibility of using less powerful drive motors, with all the advantages that follow.
