Description

The present invention relates to an aerator comprising one or

  several element (s) of vitreous or plastic material and provided

  at least one ventilation duct which can be closed by a closure device

  tion which comprises a pivoting flap for closing the or at least one said duct and means for fixing the flap to a said aerator. It is known to use, in the construction industry,

  aerators comprising one or more elements of vitreous material

  se or plastic and preferably having the dimensions or a multiple of the dimensions of the building elements, such as bricks, blocks, etc., these aerators being intended to allow the flow of air from one place to another of the construction, the two places being separated by a wall or a wall. One of the known devices

  aerator consists of a set of stackable elements and preferably

  of a prismatic form such as by superposition of

  these elements are delimited one or more ventilation ducts.

  It is also known to provide a device for closing the ventilation ducts, which can be used in particular in cold weather or by

very hot weather.

  According to one of the known embodiments, a frame is mounted on the edges of the aerator and a shutter rests in a groove of the base of the frame and can play freely in the groove to be placed in the open or closed position. A lateral stop provided on each side of the frame prevents the lateral displacement of

  the shutter when it is in the open position. This form

  The main drawback of this embodiment is that the shutter can

  to come out or even fall out of the groove of the frame during

  opening and closing pulsions. In addition, this kind of shutter device does not allow to easily place the shutter in intermediate positions between the complete closed position and the

full open position.

  According to another known embodiment, the aerator is provided with one or more shutters, at least one of them being mounted so as to be pivotable with respect to one of the elements of vitreous or plastic material which constitute the aerator and it is provided

  one or more return springs for imparting an inclination

  in a predetermined position to the pivoting shutters or at least one of these shutters. This method of construction is more stable than the previous one and makes it possible to choose a partial closure position of the ventilation device, but the use of return springs

  gives rise to corrosive risks which may create an ines-

  and the elements put in place are difficult to replace.

  to place; moreover, construction and installation are complex.

  The present invention aims at remedying the disadvantages

  known devices and providing aerator shutters aesthetic

  stable, which can be placed in the closed position or in

  open and simple and rational construction, integrating perfectly

  in a large scale manufacturing unit. Other advantages

  These will appear in the following description.

  More specifically, the invention relates to an aerator comprising one or more elements of vitreous or plastic material and provided with at least one ventilation duct closable by a closure device which comprises a pivoting flap intended to seal the at least one said conduit and means for attaching the flap to said aerator, characterized in that said flap has a pivot axis located between a closure element of the flap and at least one lever element of the flap so that, when the closure device is mounted on said aerator, tilting forces may be applied to one of the components of the shutter to pivot the shutter to a position

  closed in which its closure member closed the (s) said (s)

  duit (s), or to the other component of the pane to rotate the shutter towards

an open position.

  The shutter for aerator thus produced is particularly

  advantageous because the two components of the component are inte-

  in a single unit with both shutter and aperture functions. This arrangement provides a stable unit that can be of simple construction. The flap can preferably pivot to an open position in which the or at least one lever element

  leans against a support surface so as to give a localization

  positively in the open position. Obviously we meet

  It should be understood that this advantage can be obtained by other means, for example by shaping the pivot and its support so as to form

stop surfaces.

  It is advantageous to provide one or more ribs

  arranged on the closure element shutter. The latter is

will be significantly strengthened.

  It is possible to make the lever element (s) in the form of tabs or appendages that extend to the other side

  of the pivot axis with respect to the shutter member.

  According to a preferred embodiment where each portion

  support or lever element (s) is constituted by an extension

  of the rib or each rib.

  To ensure the operation of the shutter between its open and closed positions, the plane of the lever element (s) and the plane of the closure element of the shutter are placed in an angular position relative to the 'other. That being so, following a form

  advantageous embodiment of the invention, the closure element and the element

  of the closing shutter are constituted by plates

  juxtaposed which constitute a dihedron. This embodiment is

  particularly aesthetic and easy to manufacture; moreover, it is particularly suitable for obtaining various possibilities of use

  according to the desired function, namely the closed position, in po-

  open position or in a partially closed position.

  The choice of the position of the axis with respect to the ducts

  when the shutter is attached to the aerator makes it possible to

  a shutter which in its closed position closes all the air ducts, or only a part of them. In the latter case, the tilting of the shutter between its two positions

  allows to go from a weak to a strong ventilation.

  The dihedral embodiment is very easily adapted to the use of the aforementioned ribs which may consist of

  in these cases, in two lateral reinforcing triangles.

  Whatever the form of execution used, it is

  that the axis providing mobility of the shutter is

  made by pivots. These are advantageously fixed on the

  or the ribs (s) formed by the two lateral triangles of

  necessarily, when these are implemented.

  According to a preferred embodiment, the means

  to secure the shutter shutter to the aerator comprise a frame.

2 4 6 5 1 6 7

  The frame may, for example, include claws that cooperate with recesses or grooves provided on the aerator to ensure the attachment. An advantageous embodiment consists in providing the frame with gripping claws acting in opposite directions on one or more element (s) of vitreous or plastic material which constitutes (s)

  the aerator. In this case, it is obviously necessary that the material

  frame, or in any case clawing hooks, has the necessary elasticity characteristics. This makes it possible to ensure that the shutter is fastened to the aerator without having to fear its

  fall when handling the shutter.

  According to an advantageous embodiment, the bearing surface on which the lever element of the shutter flap comes from

  support is an integral part of the framework.

  Can be applied to the flap of tilting forces by

  any appropriate means. For example, if the aerator is placed

  In an accessible manner, it is possible to apply finger pressure directly to the flap. Preferably, at least one cord is attached to said lever member and said closure member to exert said tilting forces. Thus there can be a single cord whose two ends are connected to the respective elements of the shutter where each of the elements can be provided

  a separate cord. A voltage can be applied to a

  cable to move the shutter to a position.

  open or closed. The cord (s) may or may be attached to a suitable anchor point to hold the shutter in any intermediate position. Another way to maintain the flap

  in an intermediate position is to provide some money

  on the pivot so that the flap is held in position

by friction.

  The said cord (s) preferably pass through

holes in the frame.

  Advantageously, the shutter device comprises snap-fastening shutter devices in at least one of

its open and closed positions.

  The invention will be described more explicitly with the aid of a preferred embodiment with reference to the attached figure which illustrates, in vertical section, an embodiment of a shutter

  for aerator according to the present invention.

  In the attached figure, there is shown an aerator comprising

  three superposed elements 1, 2, 3 made of glass or molded plastic product, possibly transparent, namely a crown element 1, an intermediate element 2 and a base element 3. The elements Z and 3 are of identical construction. In particular, each of the

  elements 2 and 3 has two lateral faces connected to the metal part.

  diane by a prismatic wall forming a salient towards the summit and

  returning to the base. The return of element 2 and the salient of the

  element 3 cooperate with the lateral faces of these two elements for

  to form a conduit through which air can circulate. The configuration

  tion of the prismatic wall is such that it prevents a direct vision

  through the air circulation duct. The lower extremities of

  the basic element 3 are closed by a plate 4 to prevent penetration

  mortar in the cavity of this element when the aerator is placed in a wall. The crown element 1, of smaller height, is closed at its upper part by a wall parallel to the plate

  4 of the base member 3. To facilitate the handling of

  before being placed in a wall, the elements thus assembled from the aerator can be secured to one another, for example by an adhesive tape or by any other appropriate means surrounding the

four sides of the aerator.

  The shutter is formed by a frame 5 and a shutter of ob-

  turation 6 which is fixed on it. Lower and upper bosses, or equivalent means, are provided on the base elements 3 and top 1 of the aerator for snapping the frame of the shutter. Thus, in the example of the appended figure, the frame comprises two attachment lugs 7 arranged over the width of the frame and which snap into a groove provided for this purpose in the aerator for the upper part. Alternatively, the legs 7 can

  simply apply against the inner face of the wall of the

  1. In this case no special groove is provided. With regard to the lower part, the frame has two lugs 8 which

  are supported by clipping on two recesses 9 provided in the aerator.

  tor. For the assembly of the frame thus conceived, we first introduce the

  the upper part, and that at its maximum, in the groove, then

  quest down on the bosses of the lower part. It is obvious

  other means exercising the same function may be used.

  The hooking lugs 7 and the lugs 8 constitute claws of ac-

  stalking that act in opposite directions.

  If desired, the frame may include an inner frame for receiving a mosquito net. In addition, a housing on

  three sides may be provided to allow the installation of a cord of

  the cellular matter between the face of the aerator and the frame of the shutter. Two claws such as 10 are provided on the frame for

  allow the shutter pivots to snap into place 6.

  The shutter 6 comprises a shutter element -l 1 and an element

  lever 12 arranged on either side of the pivot axis so that, when the shutter is attached to the aerator, for example by means of the frame described above, the flap can pivot between a position making the closure of the ventilation duct and a

opening position.

  In the example illustrated in the attached figure, the

  carries a shutter member 11 and a lever member 12 formed by flat plates; these elements are respectively placed in planes forming between them an obtuse angle. All of these two elements form a dihedral which is reinforced by strengthening ribs materialized by lateral triangles 13 disposed at the ends of the flat plates. These ribs carry pivots such

  that 14 coming snap into the claws 10 of the frame 5.

  The shutter also has two holes 15, 16, respectively

  in the shutter element and in the lever element, intended to

  switch to a remote control cord from the opening and closing of the shutter cover; this cord must, of course, be fixed to the shutter. Different holes 17 are also

  provided in the frame to allow the passage of the cord.

  The attached figure shows in solid lines the shutter placed in the fully open position. The total closing position of the two air ducts is shown in broken lines. In the

  fully open position, the lever element 12 is based on the

  bearing surface of the frame 5 and is held there by a lip 18 which becomes

  with the edge of the lever element.

  The shutter element It is, therefore, due to the angle formed by the planes of the two elements, sufficiently far from the frame to allow passage to the air. In the fully closed position, the shutter element It completely closes the air ducts and is held in this position by means of a lip 19 which snaps into engagement with the edge of the shutter element. The element of

  lever 12 is then moved away from its bearing surface on the frame.

  The respective dimensions of the shutter and lever elements of the shutter can be chosen according to the requirements, for example as a function of the number of ventilation ducts of the aerator or according to the respective dimensions of these ducts if those -is not, as in the attached figure, dimensions

  identical. It can even be imagined that the lever element is

  in the case of a ventilation duct, for example, smaller

  mensions as the ducts closable by the shutter element. In this case, the shutter is never complete, but it is possible to

  regulate the flow of the incoming air according to the needs.

  It goes without saying that in all cases, the shutter shutter

  can easily be placed in an intermediate position between 1 'or -

  complete opening and closing of the shutter.

  It is obvious that the invention is in no way limited to the embodiment which is illustrated by the accompanying drawing. Many modifications can be made in the form, layout and constitution of the elements used without departing from the framework set by

  the inventive idea and which is specified in the claims below.

  As has been said previously, the embodiment can be simplified by replacing the lever element constituted here by a plate, by tongues or other appendages having the same function. We can possibly remove the frame of the shutter

  and directly apply the active elements of the shutter to the

  by means of axle holders secured to the latter. It can further be conceived that the components of the shutter shutter are not flat surfaces but concave, convex or irregular surfaces depending on the shape of the elements of the shutter or, for example, an aesthetic effect that the we want to get. Finally, it is left full freedom as to the nature of the building materials components shutter and possibly the frame, provided that it adapts to the functions that these elements are called to exercise.
