Definitions

the present invention concerns a solar covering apparatus, such as a pergola or other structure for outdoor spaces, with a covering and protection function, intended for civil use, mainly supplementary to residential areas, but also commercial, public or for exhibitions.
the pergola is provided with an upper structure with which covering elements cooperate, which generally determine a desired condition of direct or indirect irradiation, that is, of passage of air, light and water, in the area below the upper structure.
a pergola type covering apparatus typically comprises a lower support structure, formed by a plurality of structural support vertical elements, also called uprights, which are able to sustain, at a certain height from the floor or from the ground, an upper structure having the shape of a complete, or partial, quadrangular frame.
This upper structure normally consists of sustaining elements, typically horizontal or moderately inclined in the order of 5°-20° with respect to the plane of the floor, also called uprights.
a pair of lateral uprights which act as a support for the covering elements, and a pair of uprights, one at the head and one at the tail, perpendicular to the lateral uprights.
the lateral uprights define a longitudinal direction in which corresponding covering elements can move.
covering elements are operatively associated with the upper structure, which are advantageously mobile with respect to each other in order to define at least one closing operating condition that corresponds to a covering condition, in which they are all substantially coplanar with each other and reciprocally contact each other to define an actual "roof' of the structure, and a plurality of opening conditions, which correspond to respective uncovering conditions, in which they are disposed in such a way as to define corresponding compartments, more or less wide, for the passage of light and/or air or other atmospheric agents.
These solutions allow to modulate the intensity and power of the light and/or air to be allowed to enter into the pergola.
the slats of each group usually have predefined sizes and are disposed at a certain pitch from each other so that, as a function of the total number of slats provided, they determine the capacity to cover a certain width, understood as their size parallel to the longitudinal direction, when they are installed in the bearing structure.
the internal length of the support structure defined by the distance between the two head and tail uprights, has to always be a multiple of the width of the slats, or of the aforementioned pitch. Otherwise, the overall extension of the slats is smaller than the underlying area to be protected, leaving some parts uncovered, in particular when they are in the covering position.
Document JP 2017096090 A describes furnishings such as doors and dividers that separate two spaces, but are in any case able to allow or block the circulation of air through a system of mobile slats with guillotine-like movement.
One purpose of the present invention is to provide a covering apparatus provided with two groups of covering elements relatively mobile with respect to each other, in which any free space that were to be created between a terminal covering element and the corresponding upright of the support structure can be covered in a stable and safe manner, without needing to provide for specific designs and productions of the covering elements, and without interferences being generated, or other problems arising, with the movement of the covering elements.
Another purpose of the present invention is to provide a covering apparatus provided with mobile covering elements in which any free space between the terminal covering element and the corresponding upright can be compensated in a simple and effective manner.
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 covering apparatus is of the type comprising at least one upper structure having a length defined between two substantially horizontal head sustaining elements, or uprights, thereof.
the head sustaining elements are part of the upper structure.
the covering apparatus also comprises a plurality of first covering elements, or fixed slats, assembled with a certain pitch on the upper structure, and a correlated plurality of second covering elements, or mobile slats, which can be moved selectively with respect to the fixed slats.
this selective movement allows for different reciprocal positionings between the fixed slats and the mobile slats, so as to define at least one opening condition in which there are defined desired direct or indirect passages of light and/or air through the upper structure, and one covering condition in which each mobile slat is disposed offset with respect to each fixed slat and defines at least one overlap portion with at least one of the adjacent fixed slats.
this covering condition the reciprocal positioning of the fixed slats and the mobile slats, as described, substantially prevents the passage of light and/or air through the upper structure.
a summation calculated between the overlap portions is at least equal to a difference calculated between the length of the upper structure and a covering size defined between a first and a last fixed slat.
the covering size represents an imaginary surface delimited on at least two sides by the first and the last of the first covering elements or fixed slats.
the sum of all the overlap portions that are defined in the covering condition is at least equal to the size to be compensated, in order to define the complete closure of the upper structure.
the value of the summation of the overlaps can be larger than the difference between the length of the upper structure and the covering size of the fixed slats by a value of the order of centimeters.
This advantageous solution allows to keep a certain margin of overlap between the fixed slats and the mobile slats, guaranteeing in any case that the length of the upper structure is covered entirely.
each overlap portion is equal to the ratio between said difference and the number of the overlap portions to define the complete closure of the upper structure.
the upper structure also comprises two lateral sustaining elements to which the plurality of first covering elements is attached, and with which the plurality of second covering elements is associated sliding.
the first and the last of the first covering elements can be disposed in direct cooperation with respective ones of the head sustaining elements.
At least one compensation device attached to at least one of either the first or the last of the first covering elements.
the compensation device is disposed in cooperation with at least one of the sustaining elements, so as to compensate for the possible additional distance between the corresponding covering element and the corresponding sustaining element.
This advantageous solution allows to further simplify the compensation of the distance that can exist between the sustaining elements and the fixed slats.
the compensation device it is possible to reduce the conditions of modification of the pitch of the fixed slats, to the advantage of a simpler assembly of the pergola, in particular in conditions whereby the length of the support structure is different from an integer multiple of the pitch of the fixed slats.
the cooperation between the modification of the pitch and the compensation device allows to substantially standardize the sizes and positioning of the latter, as an additional advantage of the simplification and the reduction of the costs for setting up the pergola, essentially whatever the support structure's sizes in length.
the compensation device is positioned and conformed in order to at least partly overlap with the water outflow element.
the compensation device is disposed substantially coplanar with such covering plane, so as to not aesthetically impact the pergola's design.
the compensation device comprises at least one covering body that has at least one edge facing toward the closest sustaining element.
this edge is distant from the corresponding fixed slat by a measure smaller than the distance between the fixed slat itself and the corresponding sustaining element. Furthermore, the edge is disposed above the water outflow element, so as to further improve the conditions for managing the water and its outflow toward the gutter.
the compensation device comprises attachment means, which are disposed in cooperation with the first or the last of the fixed slats, in order to attach the latter to the covering body.
the attachment means can be of a substantially known type, whether of the removable or irremovable type, without in any case departing from the spirit of the inventive idea of the present invention.
a compensation device attached to the first fixed slat and a compensation device attached to the last fixed slat, so as to have a condition of compensation that is substantially symmetrical with respect to the support structure and thus define a condition in which the loads, inertias and design lines are balanced.
the compensation device is attached to the support structure.
the compensation device is attached to the water outflow element.
the compensation device is freely attached between the fixed slats, the support structure and/or the water outflow element.
Some embodiments of the present invention also concern a method for assembling a covering apparatus comprising the assembly of at least one upper structure having two head sustaining elements, the distance between them defining a length of the upper structure, the assembly of a plurality of first covering elements to the upper structure, and of a plurality of second covering elements which are mobile with respect to the first covering elements, between at least one opening condition and one covering condition, in which each of the second covering elements is disposed offset with respect to each of the first covering elements and defines at least one overlap portion with at least one first adjacent covering element.
the method comprises assembling the plurality of first covering elements and second covering elements in such a way that a summation calculated between the overlap portions is at least equal to a difference calculated between the length of the upper structure and a covering size defined between a first and a last of the first covering elements.
the attached drawings concern a covering apparatus, in this specific case a pergola 10 for outdoor spaces.
the pergola 10 typically comprises, and is defined by, four vertical uprights 11 conformed to keep an upper structure 12, also referred to hereafter as upper frame 12, in a desired raised condition.
the upper frame 12 is substantially formed by a pair of lateral sustaining elements, or lateral uprights, 13a and by a pair of head sustaining elements, or head uprights, 13b associated with each other so as to give the upper frame 12 a substantially square or rectangular conformation that delimits the zone to be covered at the upper part.
the pergola 10 further comprises a first group of slats 14, attached to the upper frame 12, and a second group of slats 15, mobile with respect to the slats 14 of the first group in a direction Z substantially longitudinal to the upper frame 12.
the slats 14 of the first group are fixed and, hereafter in the description, are also referred to as first fixed slats 14.
the slats 15 of the second group are mobile and, hereafter in the description, are also referred to as second mobile slats 15.
the lateral uprights 13a are substantially parallel to each other and to the direction Z, while the head uprights 13b are substantially parallel to each other and orthogonal to the longitudinal direction Z.
the distance between the head uprights 13b defines a longitudinal length L of the upper frame 12.
the fixed slats 14 are associated at their terminal ends with the lateral uprights 13a, in a condition substantially parallel to the head uprights 13b.
Each first slat 14 is distant from the adjacent first slat 14 by a certain pitch P1.
the set of first slats 14 spaced apart by the pitch P1 defines both a covering plane CP and also a covering size CD.
the mobile slats 15 are disposed above and substantially parallel to the first fixed slats 14, and are mounted with their terminal ends to corresponding movement guides (of a substantially known type and not shown in detail).
the movement guides can be attached to the lateral uprights 13a.
the second slats 15 are also spaced apart from each other by a certain pitch P2.
the pitch P1 and the pitch P2 can be freely the same or different from each other.
the second slats 15, in a condition of coverage of the pergola 10, are offset with respect to the first slats 14, in a position such that each second slat 15 defines two overlap portions OP with two corresponding adjacent first slats 14.
the second slats 15 can in any case be at a lower level than the first slats 14, that is, be taken, in some operating conditions, into a condition of substantial coplanarity with the first slats 14. It is not excluded, moreover, that the second slats 15 can be kept in a fixed position, and that it is the first slats 14 that move; it is also not excluded that both first slats 14 can be moved, for example in opposite directions, or with different speeds, or in different and combined movement conditions, always in order to define the desired covering and opening conditions to prevent or define desired direct or indirect passages of light and/or air.
the starting overlap portions OP have a size whereby their summation is at least equal to the difference ⁇ between the length L of the support frame 12 and the covering size CD defined by the first slats 14.
each overlap portion OP has to be at least equal to the ratio between the difference ⁇ and the number of such overlap portions which, in this specific case, based on the number of first and second slats 14 and 15, their pitch P1 and P2 and their reciprocal disposition, are in number of 6 (six).
each overlap portion OP has to be at least equal to 5/6, that is, at least approximately 0.8cm each.
This minimum size allows to compensate for the difference ⁇ , by varying the pitch P1 and P2 of the first slats 14 and of the second slats 15, until the first end slats 14 are taken into contact with the lateral uprights 13a, as shown in the comparison with fig. 3 .
the second slats 15 still define an overlap portion OP which, in this case, is functional for the management and effective drainage of rainwater or wastewater on the slats 15 themselves.
This overlap between the second and first slats 15 and 14 is advantageously taken into account as an additional value for the calculation of the minimum overlap portion OP.
one or more hydraulic seal gaskets are provided (not shown in the drawings), to prevent unwanted dripping and infiltrations between the upright 13b and the first terminal slat 14 itself.
the summation of the overlap portions OP which are defined between the second slats 15 and the first slats 14 has to be at least equal to the difference between the length L and the covering size CD.
a hydraulic drainage management gutter 16 is provided, it is particularly effective to provide a partial overlap also between the first terminal slats 14 and the corresponding gutters 16, in order to prevent both unwanted splashes and dripping, as well as the use of complex gasket systems.
This overlap between the first slats 14 and the gutters 16 is advantageously taken into account as an additional value for the calculation of the minimum overlap portion OP between the second slats 15 and the first slats 14.
a corresponding compensation profile or device 17 is associated with each of the first terminal slats 14.
the compensation device 17 substantially has the function of increasing, by a predetermined proportion, the covering size CD, in a manner substantially independent of the conformation, number and pitch P1 of the first slats 14.
the compensation profile 17 can have an "L" shape.
the compensation profile 17 comprises at least one covering body 18, the latter being provided with an edge 19 facing, during use, toward the corresponding head upright 13b.
the size of the covering body 18 is such that the edge 19 is distanced away from the corresponding first slat 14 by a measure M smaller than the distance D between the first slat 14 itself and the corresponding head upright 13b.
the edge 19 is advantageously disposed above the gutter 16, to the obvious advantage of managing the outflow of rainwater and wastewater.
the covering body 18 can have a section tapered toward the edge 19, so as to facilitate the conditions of outflow of the water toward the gutter 16.
the tapered conformation of the section of the covering body 18 can have a lower surface with a flat development, so that it can be disposed in continuity with a corresponding lower surface of the corresponding first slat 14 and, therefore, define a single covering plane CP.
the compensation profile 17 also comprises attachment devices 20 (of a substantially known type and not shown in detail in the drawings), by means of which the covering body 18 is disposed in stable and effective cooperation with the corresponding first slat 14, for example in substantial continuity with a lower surface of the latter in order to define, as stated, a single covering plane CP.
the attachment devices 20 can provide coupling, snap-in or same-shape attachment systems, or systems for attachment by means of screw elements or other, without thereby departing from the scope of the present invention.
