Definitions

  • the present invention refers to a pergola with an improved upper slat support that allows standard parts to be used in the manufacture of different models. It is especially advantageous when combined with photovoltaic equipment.
  • Some example system involves a bar connected to all slats at the same distance from the slat axes. The movement of that bar produces its coordinated rotation.
  • This system requires a hydraulic or pneumatic cylinder and a lot of power to be able to carry out the movement with any angle of the slat and arm of the turning moment. This in turn implies noise and volume of the equipment.
  • the invention consists of a pergola with rotating slats according to the claims. In its different embodiments it solves the problems of the state of the art.
  • the pergola is made up of a frame support, in turn made up of two stringers and one or more crossbars that provide rigidity to the frame. Inside the frame there is a series of rotating and parallel slats, each with an axis, arranged between both stringers. One of the stringers is straight and contains a toothed wheel integral with each
  • REPLACEMENT SHEET (RULE 26) shaft, geared in one or more motorized racks.
  • all the slats of a frame or opening are operated with the same zipper, but partitions can be created.
  • a preferred way of making partitions is to place several racks in parallel, and ensure that the toothed wheels of the different slats engage in one rack or the other.
  • the most preferred solution places the racks, at each end of the slats, on the two straight stringers. Due to the simplicity of the structure, the easiest way to execute is with a single zipper on each stringer.
  • the axes of the slats are the same at each end, it can be decided during the design or construction phase which slats are associated with each rack and, in this way, they move together forming the partition. It will be enough to place the toothed wheels at one end or the other of the slat during assembly. Thus, it is possible to make the even and odd slats move independently, that several consecutive slats (for example all those at one end) move independently of the others, and other particular solutions.

  • Figure 2 Perspective detail of the transmission between sprockets and rack in two positions (A) and (B).
  • Figure 4 Top view of examples of positions of a pergola with four partitions: A) Open; B) An open extreme partition; C) Alternate partitions and D) Open extreme partitions.
  • Figure 1 shows an example of the pergola.
  • Part of a support (1) such as pillars, walls... and one or more frames or openings with two or more stringers (2) and at least one crossbar (3).
  • the frame defines a useful surface closed by parallel slats (4).
  • the frame is generally rectangular or square, but in reality for the invention it is enough for one of the stringers (2) to be straight. It will be enough for the slats (4) to be of variable length to adapt to a pergola with a non-straight beam (2). Frequently the frame will be significantly horizontal, but it depends on the specific use of the pergola.
  • the slats (4) have separate axes (5), parallel to each other and generally equidistant.
  • the axles (5) are supported by the beams (2) by means of bearings, rollers or other systems that allow freedom of rotation.
  • Each of the axles (5) is connected to a toothed wheel (6), in turn geared in a motorized rack (7) that can be common to all the slats (4).
  • the rack (7) moves by means of a hydraulic cylinder (8).
  • the toothed wheel (6) can be complete or have a partial cut to reduce its height, for example according to a chord of the circle formed by the wheel, as seen in Figure 2.
  • the rack (7) can have teeth along their entire length or only in the area of each toothed wheel (6).
  • the translational movement of the rack (7) translates into the rotation of the slats (4) in a coordinated manner.
  • the cutout of the toothed wheel (6) serves, among other functions, to facilitate position control during assembly.
  • This system is very effective, since the translation movement of the rack (7) is not affected by the position of the slats (4) consequently, the motor can be of lower weight and power. Furthermore, it is possible to hide all the light elements inside the corresponding beam (2), protecting them from water, dust and removing them from sight. To do this, the motor and the rack (7) are arranged inside the beam (2), on the other side of the corresponding bearing or bearing. In addition, this system requires less maintenance than other similar ones, such as those that use an endless screw, especially if hydraulic cylinders (8) are used to move the racks (7).
  • FIG 3 shows a detail of an example embodiment in which the slats (4) are grouped into partitions.
  • the slats (4) are grouped in even and odd numbers. All slats (4) of the same partition move in unison.
  • two racks (7) have been arranged, one on each beam (2), and the toothed wheels (6) are placed at one or the other end of the axis (5) of the slat (4).
  • the user can activate the hydraulic cylinder of each rack (7) independently, to act on the partitions, or act on all the racks (7) in parallel to move all the slats (7).
  • Figure 4 shows different positions of the slats (4) of a pergola with four partitions.
  • Two zippers (7) are arranged on each stringer, alternately (the first on one stringer, the second on the other, the third on the first stringer). In this embodiment it is possible to align the zippers (7) on each side given that the slats (4) they affect are separated and the zippers (7) can be sufficiently separated so as not to collide.
  • Figure A all partitions are in the open position. So the pergola does not cast shadows.
  • Figure B the partition
  • REPLACEMENT SHEET (RULE 26) The one on the right is open and the others are closed. In Figure C, the partitions are alternately open or closed. In Figure D, the extreme partitions are open and the middle ones are closed. Other combinations are possible.

Abstract

La présente invention concerne une pergola à lames tournantes qui comprend un support (1) d'un cadre formé par deux ou plus de deux longerons (2) et d'au moins une barre transversale (3), au moins un des deux longerons (2) étant droit, et une série de lames (4) tournantes à axes (5) parallèles entre eux, supportés par les longerons (2). Les axes (5) sont incorporés dans le longeron (2) directement dans les roues dentées (6) engrénées dans une ou plusieurs crémaillères (7) motorisées.
