Definitions
- the present invention regards a covering apparatus according to the preamble of the independent claim.
- the present apparatus is intended to be employed for covering external surfaces, protecting them from atmospheric agents and in particular from the sun and rain.
- the present covering apparatus is indicated for making pergolas, verandas and more generally covering structures, both in gardens of private homes and in open spaces of public places, such as for example restaurants, hotels, bathing establishments or other structures.
- the covering apparatus object of the present invention, thus falls within the industrial field of production of blinds for covering outside environments.
- brise 140 in the jargon of the field, which comprise a support structure, e.g. with canopy, fixed to the ground and provided with two lateral longitudinal members which support a series of oscillating blades adapted to protect an underlying ground surface.
- Brise in covering apparatuses are for example known which comprise a series of oscillating blades, each of which provided at its ends with rotation pins hinged with the corresponding longitudinal members.
- Such apparatuses also comprise movement means connected to the oscillating blades in order to actuate the latter to rotate between a closed position, in which the blades are placed substantially horizontal and partially superimposed on each other in order to prevent the passage of light and/or rain, and an open position, in which the blades are placed tilted, between them delimiting openings for the passage of light.
- Covering apparatuses are also known whose blades can also be moved, by means of further movement means, between a packed configuration, in which the blades are side-by-side each other in proximity to a same side of the covering apparatus, and an extended configuration, in which they are placed spaced from each other.
- Such apparatuses for example comprise two guides made on the corresponding longitudinal members, and on each guide a series of carriages is mounted which rotatably carry, mounted thereon, the rotation pins of the corresponding covering blades.
- at least one of the ends of a first covering blade carries, mounted thereon, an actuation lever, tilted with respect to the blade, which terminates with an engagement wheel slidably associable with a fixed track positioned on the longitudinal member in order to actuate the rotation of the blade when it is in extended configuration.
- each blade is connected to the others in order to simultaneously rotate following the rotation of the first covering blade.
- a further drawback of the covering apparatuses of known type lies in the fact that the rotation of the blades by means of the transmission of the movement through a single blade is difficult and mechanically disadvantageous. This can cause frequent failures in the actuation means and therefore overall the covering apparatus is unreliable in use.
- a further drawback of the above-described solution lies in the fact that during packing the blades can be stuck on each other and be damaged. Indeed, during packing, the actuation lever is not connected to the fixed track and therefore the blades are not maintained fixed in a predetermined position. Hence, overly high oscillations in translation or particularly windy climate conditions can bring the blades to rotate in an uncontrolled manner and hit against each other or remain stuck.
- the patent US 9,175,511 describes a further covering apparatus of known type, in which the carriages are connected to each other by a pantograph mechanism having one end constrained to a fixed guide element and the other end connected to a head carriage.
- the covering apparatus comprises a motor which actuates a worm screw, which is engaged in a nut screw of the head carriage which, following the rotation of the worm screw, is actuated to slide along the lateral longitudinal members, causing the opening or the closing of the pantograph, which in turn determines the sliding of the other carriages, maintaining them equidistant.
- the carriages are provided with vertical slots in which several pantograph junction pins are inserted.
- the problem underlying the present invention is therefore that of eliminating the drawbacks of the solutions of known type mentioned above, by providing a covering apparatus which is functionally and designably flexible and versatile in use.
- a further object of the present invention is to provide a covering apparatus which allows executing, in an entirely efficient manner, the packing movement of the covering blades in a manner independent from the opening movement of the blades themselves.
- a further object of the present invention is to provide a covering apparatus that is reliable in use.
- a further object of the present invention is to provide a covering apparatus that is structurally simple and inexpensive to make.
- reference number 1 overall indicates the covering apparatus that is the object of the present invention.

- the aforesaid first maintenance section 65 stably maintains the covering blades 3 in open position during the translation between extended configuration and packed configuration, preventing the covering blades 3 themselves from being angularly shifted from the open position.
- the translation profile 62 is provided with a second maintenance section 66 which is substantially parallel to the translation direction S and which, when the covering blades 3 are in the extended configuration, engages the translation cam follower 50, at least when the rotation cam follower 40 is engaged with the movement section 63 of the rotation profile 61.

- the profiles 61, 62 can be provided with multiple displacement sections and multiple maintenance sections based on the movement requirements of the covering blades 3.
- the profiles 61, 62 can be configured in a manner such that the movement section and displacement section 63, 64 simultaneously engage, respectively, the rotation and translation cam followers 40, 50.

- the movements of the covering blades 3 between extended configuration and packed configuration and between open position and closed position are advantageously controlled independent of each other.
- one of the cam bodies 60, 60A, 60', 60" is placed at the head portion 21' of the lateral beams 21 while the other is placed in a position substantially intermediate between the head portion 21' and the bottom portion 21" of the lateral beams 21.

- the rotation cam follower 40 is mounted at least on one between the first arm 82 and the second arm 85, still more preferably at the pivoting axis.

- the second movement rod 56 comprises a first connection portion 56', rotatably connected to the first movement rod 55 of a preceding pair 54' in the series of pairs of rods 54, a second connection portion 56", rotatably connected to the first movement rod 55 of a subsequent pair 54" in the series of pairs of rods 54, and a central connection portion 57, rotatably connected to the first movement rod 55 of the aforesaid pair of rods 54.
- the carriages 52 are advantageously rotatably constrained to a corresponding connection portion between the first connection portion 56' and the second connection portion 56" (preferably the first connection portion 56') of the second movement rods 56 of alternate pairs of rods 54.
- the second movement device 5 advantageously comprises at least one second lateral guide (not illustrated in the enclosed figures), arranged on the corresponding said lateral beam 21 and extended advantageously along the first extension direction X of the lateral beam 21 itself.
- each first connection portion 56' carries, mounted thereon, a slide element 58, for example a wheel, slidably engaged with the second lateral guide.
- the translation cam follower 50 is fixed to the second connection portion 56" of the second rod 56 of at least one pair of rods 54.
- the movement of the translation profile 62 along the translation direction S brings the translation cam follower 50 to be moved vertically and consequently brings the first and the second movement rods 55, 56 connected to a pantograph to be extended or packed (based on the movement sense of the translation profile 62).
- the carriages 52 and the corresponding covering blades 3 are therefore consequently driven by the movement device 53 to slide along the first lateral guides 51.
- the first movement means 4 comprise two actuation elements 41 (in particular two movable bars), each placed in a corresponding lateral beam 21 and connected in the previously-described modes to a corresponding end 31 of the covering blade 3.
- the second movement means 5 also comprise two movement devices 53, each placed in a respective lateral beam 21 and connected to the carriages 52 on which the corresponding ends 31 of the covering blades 3 are mounted.
- the cam actuation means 6 are placed at both ends 31 of the covering blades 3, by means of arranging the profiles 61, 62 along each of the lateral beams 21, for example by arranging, at both lateral beams 21, the cam bodies 60, 60A, 60', 60" treated in the above-discussed embodiments.
- motor means 7 are provided at both lateral beams 21, e.g. by means of linear actuators 71, 71', 71" according to the above-discussed configurations.
- the motor means (and in particular the linear actuators 71, 71', 71") are synchronized by means of the logic control unit, so as to simultaneously move the cam movement means 6 at both ends 31 of the covering blades 3 in order to ensure the correct movement of the latter.
- the movement of the cam movement means 6 can be mechanically synchronized by means of a single rotary actuator placed within one of the front beams 22 and mechanically connected to the rotation profiles 61 and/or to the translation profiles 62 through motion transformation means.
- the motion transformation means can comprise two transmission shafts, each connected to a transmission belt in turn provided with one portion fixed to the respective rotation profile 61 and/or translation profile 62.
- the movement of the covering blades 3 from the packed configuration with the covering blades 3 in open position to the extended configuration with the covering blades 3 in closed position occurs by means of the initial movement of the rotation profile 61 and of the translation profile 62 along the movement direction S. From such movement, one obtains the simultaneous sliding of the rotation cam follower 40 along the first maintenance section 65, maintaining the covering blades 3 in open position, and of the translation cam follower 50 along the displacement section 64, in particular downward, moving the covering blades 3 from the packed configuration to the extended configuration.
- the continuation of the movement of the cam actuation means 6 along the movement direction S advantageously brings the rotation cam follower 40 to exit from the first maintenance section 65 in order to engage the movement section 63, and the translation cam follower 50 to exit from the displacement section 64 in order to preferably engage the second maintenance section 66.
- the rotation cam follower 40 slides along the movement section 63, in particular downward, actuating the covering blades 3 to rotate towards the closed position, and the translation cam follower 50 slides along the second maintenance section 66, maintaining the covering blades 3 in extended configuration.
- the rotation profile 61 and of the translation profile 62 along the movement direction S in a sense opposite the preceding, one advantageously obtains the opposite movement of the covering blades 3 from the extended configuration with the covering blades 3 in closed position to the packed configuration with the covering blades 3 in open position.
- the cam means 6 can also comprise more than one translation cam follower 50 engaged with a same or with separate translation profiles 62, and/or more than one rotation cam follower 40 engaged with a same or with separate rotation profiles 61.
- the rotation profile 61 of the cam means 6 (adapted to drive the rotation of the covering blades 3) is substituted by a different drive device, such as for example a pantograph kinematic mechanism placed as a connection between the covering blades 3 and the first movement means 4.
- the invention thus conceived therefore attains the pre-established objects.
