Definitions

  • the present invention relates to a ventilation device with a removable rotary closure element, which device comprises a grid with two elongated elements between which an opening is formed and with two end pieces by which the elements are connected, and a closure element which is mounted so as to be able to rotate in the grid between a closed position where it closes the opening and a ventilation position and which also has two elongated elements between which an opening is formed and two end pieces by which the two elements are connected, these end pieces each comprising a shaft section which extends in the axis of rotation of the closure element and which is mounted in an end piece of the grid, this last end piece being provided with a guide for the shaft section, the end of the opening projecting from an outside side of the gr ille forming a passage through this grid for the closure element, not including the end pieces, in the ventilation position.
  • a ventilation device of this type is described in document EP-A-0257669.
  • the axis sections of the end pieces of the closure element are flattened in the same direction as the closing element and the guide tracks of the terminal parts of the grid are omitted on the same side as the mouth of the grid opening.
  • the closure element can be removed from the grid in two positions together with its end pieces without the end pieces of the grid having to be disassembled, but means are provided for locking the closure element in the ventilation position in the wire rack. If you want to remove the closing element, you must bring it to a special position different from the opening position, which is not possible with the control of the closing element which cannot normally move this element only from the ventilation position to the closed position and vice versa. The removal of the closure element is therefore not always easy.
  • the object of the present invention is to remedy these drawbacks and to provide a ventilation device provided with a removable rotary closing element, this closing element together with its shaft sections being firmly supported in the terminal parts of the grid, while the removal of the closure element can still be done so very easy.
  • the terminal parts of the grid each comprise at least two parts, namely a fixed part which is connected to the elongated elements of the grid, forms a part of the above-mentioned guide system over a maximum of 180 ° on the side of the section d 'concerned shaft opposite the aforementioned external side of the grid and is provided on the side of this shaft section opposite the aforementioned external side of the grid with a passage for this section of tree, and a removable part which forms on this last mentioned side of the shaft section a complementary part of the guide system and thus keeps the shaft section in place, while means are provided for locking this removable part with respect to the fixed part .
  • the means used to block the removable part with respect to the fixed part of the terminal part of the grid include elements which are themselves mounted on at least one Parties.
  • These means advantageously consist of snap-fastening members on one part and ribs on the other part.
  • the fixed part of an end piece of the grid projects on the side opposite to the axis section outside a part of the removable part and the means comprise, to block the parts of this end piece against each other, a locking piece which is removably attached, on the aforementioned side of the removable part, to the projecting part of the fixed part.
  • the removable part of at least one of the terminal parts of the grid is provided with an opening through which a control lever connected to the concerned axis section passes.
  • This control lever is mounted in the axis section preferably removably.
  • a strip of anti-insect gauze which is arranged with its two longitudinal edges inserted in grooves which the two elements of the grid are provided along the mouth of the opening.
  • the removable part of at least one of the end pieces of the grid is located with a part close to the ends of the grooves so that this part prevents the strip of insect-resistant gauze from being released along the these ends.
  • the ventilation device consists of a grid 1 to be incorporated into a window structure and provided with a ventilation opening 2 and a closing element 3 mounted so as to be able to rotate in the grid 1 to close the opening 2.
  • the closure element 3 consists of two elongated elements formed by flat metal sections 4, between which an opening 5 is formed, and two end pieces 6 of plastic material which are firmly connected to the two above-mentioned sections 4 via projections glued to the profiles 4.
  • Each of the end pieces 6 comprises a section of shaft facing outwards which is formed by a circular collar 7 which is concentric with the axis of symmetry of the closing element 3 which is also the axis of rotation of the element 3.
  • the collar 7 is provided with a recess 8 intended for a control lever 9, which recess 8 is circumscribed by a reinforcement 10 on the internal side of the collar.
  • the grid 1 is similarly made up of two longitudinal elements, namely an upper element 12 and a lower element 13, between which is formed the ventilation opening 2 and two end pieces 14. Each end piece 14 is connected to the two elements 12 and 13 using screws 15. Each of elements 12 and 13 is provided with a thermal discontinuity and consists in fact of two sections separated from one another, 16 and 17, respectively 18 and 19, which are connected to each other by an insulating plastic strip 20.
  • the end pieces 14 not only block the two elements 12 and 13 with respect to each other, but also form bearings for the shaft sections of the closing element 3 formed by the collars 7. They have for this purpose an annular guide 21 which is concentric with the axis of rotation of the closure element.
  • the elements 12 and 13 and the end pieces 14 have, on the outer periphery of the grid, a shape such that this grid can be easily mounted in a window structure naturally with the upper part 12 above and with the above-mentioned external side. from the practically vertical grid to the internal side of the window structure.
  • the mouth of the opening 2 on the other side of the grid 1 is disposed below, since, on this other side, the upper part 12 of the grid forms a cap which goes up to the lower edge of grid 1.
  • the end 23 of the opening 2 which is located between the mouth of the latter on the external side named first of the grid 1 and the element of closure 3, has dimensions such that it forms a passage for the closure element 3 without the end pieces 6 and for the ventilation position, which is the position presented in the figures, in which the profiles 4 are arranged horizontally , but in other positions, it prohibits the passage of the closure element.
  • the two profiles 4 close the ventilation opening 2 completely.
  • the profiles 4 are moreover provided with a groove in which is mounted a sealing brush 24.
  • the two profiles 4 come, by means of these brushes 24, into contact with edges 25 and 26, respectively 27 and 28 so that the difference between edges 25 and 26 on the edge of the aforementioned external side of the grid determines the size of the aforementioned passage.
  • the fixed part 29 consists, as can be seen above all in FIG. 6, of an end plate flat, of ribs which are on this plate on the outside side for mounting in the window structure, of a peripheral flange which is on the inside side of the end plate and which connects to parts 12 and 13 of the grid 1, but is interrupted on the above-mentioned outer side, therefore close to the mouth of the opening 2, and of ribs which are located on the inner side of the end plate to reinforce and to block the elements 12 and 13.
  • a of these ribs forms a part 31, that is to say in fact half of the aforementioned guide 21 for a collar 27 of the closing element 3.
  • This part 31 describes a semicircle and is situated completely on the edge of the collar 7 opposite the mouth of the opening 2 or the aforementioned external side of the grid 1.
  • the part 29 is free of ribs so that this part 29 forms a passage to this external side for the e collar 7.
  • the shaft section of the closing element 3 formed by the collar 7 can be removed from the part 31 of the guide 21 and therefore from the end piece 14.
  • each end piece 14 forms a closure for the aforementioned passage as well as the rest of the guide 21.
  • the removable part 30 comprises a part of semi-circular shape 32 which constitutes therefore the other half of the guide 21.
  • This part 32 is provided, at the halfway point of the arc which it describes, with an elongated opening 33 for the control lever 9.
  • a round part 35 of the same diameter as the collar 7 is connected to the first edge and to the hollow side of the part 32 of the guide 21.
  • this round part 35 is inserted between the collar 7 and the flat end portion of the fixed portion 29 up to the portion 32 of the guide 21.
  • an edge 36 which, when the removable portion 30 is installed in place , extends to the aforementioned outer side of the grid 1.
  • the part 30 is provided on both sides, near the round part 35 and the abutment parts 34 which are connected to it, with a elastic member 37 thickened at its end.
  • the two members 37 form latching members which, when the part 30 is in place, hook by their thickened end behind the ribs 38 which are on the inside of the flat end part of the fixed part 30.
  • a locking piece which consists of an elongated plate 39 provided with two pins 40.
  • One side of the wafer 39 has an arcuate cutout and fits on a rim of the curved part 32 of the guide 21 located near the opening 33.
  • the two pins 40 fit into openings 41 formed in part of the flat end plate of the fixed part 29 which projects outside this curved part 32.
  • the mouth of the opening 2 on the above-mentioned outer side of the grid 1 is still closed by a strip 42 of insect-proof gauze.
  • This strip is slid by its two longitudinal edges into grooves 43 which are formed on either side of the mouth in the elements 12 and 13 of the grid 1.
  • the edges 36 of the removable parts 30 extend to the vicinity ends of these grooves 43.
  • the edge 36 of the first end piece 14 is closed and closes one end of the grooves 43 so that the strip 42 cannot slip out of the grooves.
  • the rim 36 of the other end piece 14 is on the other hand provided with a groove 44 which is situated opposite the other ends of the grooves 43 and by which the strip 42 can be slid.
  • the release through this groove 44 of the strip 42 is however, when the ventilation device is completely disassembled, prohibited by the lever 9 which engages through the opening 33 in the removable part 30 of this end piece 14.
  • This control lever 9 just like also the other control lever, has at one end two elastic members provided with thickenings so that these levers 9, as can be clearly seen in FIG. 5, can be snapped into this end piece 14 through the opening 33 of the corresponding end piece 14, the recess 8 and between the reinforcements 10 of the collar 7.
  • the control lever 9 which is contained between an edge 36 of the removable part 30 and the plate 39 of the locking piece 39, 40, prohibits any movement in the axial direction and therefore the loosening of the locking piece 39, 40.
  • a small slat 45 which extends obliquely over the mouth of the opening 2.
  • This slat 45 is located with its ends slid in the grooves 46 which extend along the grooves 43 in the elements 12 and 13.
  • the grooves 43 and 46 face one another.
