Description

JALOUSIE TYPE WINDOW.

The present invention relates to a window of the jealousy type comprising a metal frame defining an opening in which are arranged shutters, mounted in fixing on horizontal bars, each movable in rotation about their longitudinal axis and in engagement each with an actuating mechanism by the operation of which the bars are simultaneously rotated synchronously and the flaps driven to a closed position or to an open position.

A window of this type is notably known by the commercial name of "Duro".

One of the drawbacks of the windows of the prior art lies in the fact that the actuation mechanism is placed in the opening defined by the frame and this laterally to the shutters and bars, which turns out to be unattractive and bulky. Furthermore, the arrangement of the mechanism inside the opening reduces the useful width of the latter. Finally, it should be noted that due to its arrangement, the action mechanism is not protected from dust and abrasive particles which can be transported by the wind.

The aim of the present invention is to solve the above-mentioned problems by proposing a window of the jealousy type in which the actuation mechanism is hidden and protected and situated outside the opening defined by the frame.

For this purpose, the window of the jealousy type according to the present invention comprising a frame 1 consisting of one assembly of two vertical uprights 2 with two horizontal crosspieces, defining an opening in which are arranged shutters 4 mounted in fixing on horizontal bars extending from a vertical upright 2 to the other in the plane of the opening, said bars being each mounted in rotation about their longitudinal axis and each being engaged with an actuating mechanism by the operation of which the bars 3 are rotated and the shutters maneuver towards a closed position or towards an open position is essentially characterized in that: - the vertical uprights 2 are each constituted by a profile having a U-shaped cross section in order to determine a vertical housing, lateral to the opening of the window, open opposite the opening and separated from said opening by the core 13 of the profile which is a vertical wall, ortho gonal at the plane of the opening, - each bar 3 along its axis of rotation is equipped with two end pivot pieces 9 each engaged in a rotation guide bearing 13A in the form of a cylindrical bore passing through the wall 13 constituting the core of the upright, - the actuating mechanism is mounted in the vertical housing of one of the uprights 2 and comprises an irreversible motor assembly provided with a rotary output shaft 19, of socket force, to which is fixed a lever 20 at the end of which is articulated the end of a link 21 articulated by its other end to one of the mobile elements of a movement transmission constituted by an operating rod 6, extending vertically in the housing of the upright to which several rods 8 of equal lengths articulated, parallel between them, developing perpendicular to the plane of the opening and each fixed to a pivot piece 9 and to one.

According to another characteristic of the invention, each pivot part 9 passes right through the wall 13 of the corresponding upright by passing through the corresponding bearing 13A and comprises a pin 11 engaged in a housing 12 formed in the corresponding end of the bar, a cylindrical seat 9A extending said pin axially cooperating in guiding in rotation with the bearing 13A and an end portion 9B axially extending the cylindrical seat 9A in the vertical housing formed by the corresponding upright and separated from the latter by a shoulder, said part 9B terminal receiving in fixing the corresponding rod 8. According to yet another characteristic of the invention, each pivot part 9 in its tenon 11 has a diametrical slot 23 dividing said tenon into two parts. In addition, each pivot piece 9 is traversed right through along its central axis of symmetry by a longitudinal bore 24 in which is introduced a locking member 25 which performs on the one hand a radial expansion of the stud 11 in order to ensure the blocking by adhesion of said stud 11 in the housing 12 of the corresponding end of the upright 2 and which, on the other hand, fixes the rod 8 corresponding to the terminal part 9B, said rod 8 being provided with a hole in which engages the locking member 25.

In FIG. 1, a window of the jealousy type is shown comprising a metal frame 1 constituted by the assembly of two vertical uprights 2 of U-shaped cross section with a horizontal upper cross member and a horizontal lower cross member. These two crosspieces also have a U-shaped cross section. Relative to the quadrangular opening determined by the frame, the wings of the profiles constituting the uprights 2 and the crosspieces are parallel to the plane of the opening and oriented opposite the latter. while the web of these sections is perpendicular to the plane of said opening. More precisely, the opening is delimited on the left and on the right by the upper surface of the core of the left and right uprights and above and below by the upper surface of the core of the upper and lower crosspieces.

The quadrangular opening as defined receives shutters 4 of generally rectangular shutter each mounted in attachment to a rotary bar 3. horizontal, cooperating with an actuating mechanism which is mounted in the vertical housing formed by one of the uprights.

As can be seen, the shutters can be fixed by rivets or screws on their respective bars (Figure 4) or else, if they each consist of a glass slide, be positioned by one of their longitudinal edges in a gutter made on any the length of their respective bars (Figure 9). According to another embodiment, (FIGS. 9 and

10), the shutters and their bars are in one piece.

As can be seen in Figures 3, 9 and 10, each flap is offset from its bar so that its center of gravity is also offset from the axis of rotation of its bar. Behind the bar, the flap forms a heel. In the closed position, the flaps overlap each other and extend downward from their bar. Still in this closed position, the heel of each flap develops above the corresponding bar and is covered by the lower part of the flap positioned immediately above. Such a closed position is shown in Figure 9. In the open position the flaps develop perpendicular to the opening.

Each bar 3 extends horizontally from one upright to the other and receives at each of its ends a pivot piece 9. The two pivot pieces 9 that each bar has are engaged respectively in a bearing 13A in the core of the left upright of the frame and in a bearing 13A in the core 13 of the right upright of the frame. The bearings 13A are in the form of a cylindrical bore passing right through the core 13 of the corresponding amount.

Each pivot piece 9 passes right through the wall 13 of the corresponding upright by passing through the bearing 13A and comprises a stud 11 engaged and locked in a housing 12 formed in the corresponding end of the bar, said housing being of complementary shape to that of the tenon, a cylindrical bearing 9A axially extending said tenon cooperating in guiding in rotation with the bearing 13A and an end portion 9B axially extending the cylindrical bearing 9A in the vertical housing formed by the corresponding upright and separated from the latter by a shoulder constituting stop and opposing the passage of the terminal part 9B through the bearing 13A. The housing 12 presented by the bar at each end follows the shape of the tenon which ensures perfect coaxiality between the bar and the pivot pieces 9. The housing 12 which each bar has at each end can be produced by machining, for example, in the bar or, according to another arrangement of the invention, in an insert 18 engaged and locked in the corresponding end of the bar. According to this embodiment, the bar is hollow, the insert pieces 18 can be engaged in force in their bar which will ensure their attachment to them.

The end portion 9B of each pivot piece 9 is integral with an actuating mechanism mounted in the vertical housing of the upright. This actuation mechanism comprises an irreversible motor assembly provided with a rotary PTO output shaft 19 to which is fixed a lever 20 at the end of which is articulated the end of a link 21 articulated by its other end at the one of the movable elements of a movement transmission constituted by an operating rod 6 extending vertically in the housing of the upright to which several rods 8 are articulated fixed respectively to the pivot parts 9 each to the end part 9B of the part corresponding pivot. The rods 8 of equal length, parallel to each other, define in combination with the rod 6 and the pivot pieces 9 deformable parallelograms, the deformation of the parallelograms and therefore the pivoting of the pivot pieces 9 and consequently the rotation of the bars 3 and flaps 4 being obtained by displacement of the rod 6 vertically in one direction or the other.

According to the preferred embodiment, the link 21 is articulated to the rod 6. The rod 6 is in the form of a rigid strip of rectangular cross section arranged parallel to the wall 13 at a distance from the latter.

The rod 6 receives a hinge pin 31 of the connecting rod 21. This hinge pin has a head forming a shoulder and is engaged in an orifice provided for this purpose in the rod 6 and crossing it right through. The stepped head of one axis, the diameter of which is greater than that of the orifice of the rod, is engaged between the wall 13 and the said rod. Furthermore, the axis has a sufficient length to form a projection relative to the rod on which the link 21 is articulated which develops perpendicular to said axis. The clearance between the head of the axis and the wall 13 is low, which prevents the unexpected extraction of the axis. To help maneuver the rod in a direction corresponding to that of the opening of the flaps and to compensate for the resistant moment generated by the weight of the latter due to the offset of their center of gravity relative to the axis of rotation of the corresponding bar, a compensating spring 22 is provided, fixed on the one hand to one of the movable elements of the motion transmission and on the other hand to a fixed point on the upright, said spring 22 urging the motion transmission in the direction of the opening of the flaps 4. Preferably, the compensation spring, which can be a coil spring, is fixed to the operating rod. Preferably, in order to balance the forces on the two pivot parts 9 fitted to each bar 3, two movement transmissions with spring are provided, housed respectively in one upright and in the other. However, only one of these two transmissions will cooperate directly with the engine assembly.

Each link 8 is rigidly fixed to the corresponding pivot part 9 by a locking member 25 elongated such as a rivet or a screw engaged in a bore of the connecting rod on the one hand and in a longitudinal bore 24 of the insert part 9 on the other hand, this latter bore passing right through the insert part and being practiced along the central axis of symmetry of said part, said drilling opening into a diametral slot 23 dividing the tenon 11 into two parts, the introduction of the locking member in the longitudinal bore then between the two parts of the tenon a radial expansion of the latter in order to ensure its blocking by adhesion in the housing 12. Furthermore, this blocking member fixes the connecting rod 8 to the terminal part 9B of the insert part 8. In order to avoid any sliding of the rod relative to the corresponding insert part during the transmission of forces, the terminal part 9B of each pivot part 9 has a diametral slot 10 hollowed out in its planar front face in a manner re-secant to the longitudinal bore 24 in which is engaged and fixed the corresponding rod 8. According to another embodiment, the terminal part 9B of each link is extended axially by a boss of polygonal cross section and that the link has an orifice of polygonal section of shape complementary to that of the straight section of the boss, said link by its polygonal orifice being engaged on the boss.

According to the preferred embodiment, the motor assembly of the actuation mechanism is housed in a housing 26 inserted in the vertical housing of the upright 2 corresponding by passage through a front opening 27 formed in one of the wings of said upright. Furthermore, the assembly is removably attached to said upright. Furthermore, the link 21 is not fixed to the hinge pin 31 but only engaged on the latter. Thus, by lateral movement of the housing, taking the dimensions of the opening 27 into account, it is possible to disengage the link 21 from the axis 31 and to proceed with the removal of the engine assembly with a view to its replacement or replacement. repair.

The housing 26 is preferably provided with a base 28 for fixing to the upright 2, this base coming to bear against the peripheral edge of the opening 27. A motor assembly with a housing st shown in particular in FIGS. 2 and 5 to 8.

According to a first embodiment, the motor assembly is constituted by a toothed wheel 16 mounted in rotation in the housing and by an endless screw 15 mounted in rotation in the housing and cooperating in gear with the toothed wheel 16. This toothed wheel is wedged on the shaft 19 which externally to the housing receives in fixing the lever 20. The worm 15 is wedged on a shaft 29 engaged in a bore of the base 28 of the housing 26 to receive externally to the housing 26 a member maneuver which may be a handle 14 or an electric motor. The worm and gear wheel system and designed so as to be irreversible, that is to say that the rotational movement of the screw and the wheel can only be obtained by application of a driving torque on the screw only. So the external stresses exerted on the shutters 4 by the wind for example can not cause the modification of their angular position in the opening of the window. In the case where the operating member is a handle, it is necessary that the latter is moved away from a possible wall which would develop perpendicular to the window adjacent to the latter. For this reason, the central geometric axis of symmetry of the worm 15 and its shaft 29 extends in an oblique direction relative to the plane of the opening defined by the frame, the handle 14 carried by the shaft. 29 being offset towards said opening. Such an arrangement is shown in FIGS. 11 and 12.

As a variant, the motor assembly may be constituted by an electric motor housed in a box or not and associated with controls external to the window.

Finally, it should be noted that the window as described has sealing elements such as seals arranged in particular in grooves made in the heels of the flaps 4, these seals in the closed position of the flaps being compressed in their grooves by the lower part of the shutter immediately above. The window will comprise along the vertical edges of the opening defined by the frame of the sealing joints being in the form of vertical cords.
