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 covering blades carries, mounted thereon, an engagement wheel which is slidably inserted in an actuation bar which is movable on a plane orthogonal to the covering blades in order to actuate the simultaneous rotation of all the blades when they are in extended configuration.
  • the oscillating blades of the above-described known apparatuses are generally provided with a substantially tubular elongated body, at whose ends two lateral caps are mounted.
  • the rotation pins of the blade are generally fixed to the lateral caps.
  • the oscillating blades are assembled during production of the covering apparatus, by fixing the lateral caps to the corresponding ends of the elongated body of the blade, for example by means of fitting insertion and fixing screws.
  • the blades are generally mounted on the lateral longitudinal members, by hinging each end of the blades to a support profile of the corresponding lateral longitudinal member, and connected to the movement means adapted to actuate the movement of the blades.
  • the lateral longitudinal members are generally close on top with a corresponding coverage profile, aimed to conceal the mechanical components of the covering apparatus.
  • a first drawback of the aforesaid known covering apparatuses lies in the fact that, during installation, the mounting of the blades is long and complex, since, in particular, the hinging of each blade (with length of several meters) requires the intervention of multiple operators in order to rotatably connect the pins at the ends of each blade to the longitudinal members.
  • a further drawback of the covering apparatuses of known type is due to the fact that, if it is necessary to remove even only one blade (due to breakage, malfunctioning or other reasons), it is necessary to remove at least the upper profiles of the longitudinal members. Indeed, the pins of the blades are directly connected to the movement means, which are placed within the longitudinal members. Therefore it is not possible to disconnect the pin from the frame without opening the closure profile for accessing the movement means.
  • a further drawback of the known covering apparatuses lies in the fact that the inspection and the maintenance of the parts inside the longitudinal members, such as for example the movement means, is difficult. Indeed, the internal components of the covering apparatus can only be inspected between the openings between the blades when the latter are in open configuration, or by always removing the covering profile of the longitudinal members. In the first case, there is little available space and it is poorly lit, since it is at least partially shaded by the blades themselves. In the second case, the operations to be performed, the manpower and the times necessary even for simple maintenance operations are generally excessive with respect to the actual size of the problem.
  • each covering blade comprises, at the ends thereof, end caps which are each provided with corrugated grooves in which pins are inserted for coupling an articulated movement system.
  • the end cap of each blade is pivoted around a rotation pin connected, by means of a lever, to the pantograph movement system.
  • the coupling pins slide within the corresponding grooves in order to allow the rotation and translation movements of the blades.
  • the configuration of the latter solution of known type is only aimed to guide the movement of the already-mounted blades and, therefore, it is unable to resolve the aforesaid drawbacks tied to the operations of installation and maintenance of the covering apparatus.
  • the problem underlying the present invention is therefore that of eliminating the drawbacks of the abovementioned solutions of known type, by providing a covering apparatus whose blades are easy and quick to install.
  • a further object of the present invention is to provide a covering apparatus, which can be easily inspected.
  • a further object of the present invention is to provide a covering apparatus which allows a simpler and quicker maintenance.
  • a further object of the present invention is to provide a covering apparatus which is structurally simple and inexpensive to attain.
  • reference number 1 overall indicates the covering apparatus that is the object of the present invention.
  • the present covering apparatus 1 is indicated for making pergolas, verandas and more generally covering structures of outside environments, such as for example gardens of private homes and open spaces of public places such as restaurants, hotels, bathing establishments etc.

  • the support structure 2 comprises two further second columns 26 placed to support the bottom portions 21" of the corresponding lateral beams 21, in this manner attaining a self-supporting structure, in particular with substantially parallelepiped shape.
  • the support structure 2 of the covering apparatus 1 is backed against a vertical wall (such as for example the wall of a building), at which the head portions 21' or the bottom portions 21" of the lateral beams 21 are anchored.
  • the head portions 21' and the bottom portions 21" of the lateral beams 21 of the support structure 2 are respectively supported by a first and by a second vertical wall that face each other, such that the support structure 2 of the covering apparatus 1 is interposed between the two aforesaid vertical walls.
  • the covering apparatus 1 comprises a series of covering blades 3 placed one after the other according to the aforesaid first extension direction X of the lateral beams 21, preferably from the head portions 21' to the bottom portions 21" of the lateral beams 21, and advantageously actuatable for closing the aforesaid upper opening of the support structure 2, respectively so as to cover the underlying ground surface in order to protect the latter from sun and/or rain.
