Definitions

  • the present invention relates to a window stay for maintaining the window sash in a determined opening position.
  • Known window stays generally comprise a stop arm mounted on a ball joint fixed to the fixed frame and an element fixed to the leaf, the stop arm being able to cooperate with said element to immobilize the leaf.
  • the stop arm is simply engaged on the element fixed to the leaf and it is easy to open the window from the outside by passing your hand through the half-open to raise the arm.
  • the object of the invention is to provide a window stay which can be placed both on the horizontal crosspieces and on the vertical uprights of the window, and which in addition cannot be opened from the outside.
  • the subject of the invention is a window ajar comprising a stop arm connected at one end to the fixed frame and an element fixed to the leaf, the stop arm being able to cooperate with said element to immobilize the leaf in an open position.
  • the stop arm is pivotally mounted relative to the fixed frame along an oblique axis relative to the perpendicular to the joint plane defined between the leaf and the fixed frame in the area of the stay-open device, the arm being at rest substantially parallel to the joint plane, and the free end of the stop arm and said element are arranged so that, the stop arm having been previously moved from its rest position, the opening of the leaf causes the engagement with blocking of said element on the free end of the stop arm and the immobilization of the latter.
  • stop arm is, in the rest position, di-rigged parallel to the joint plane makes it possible to mount it as well on a vertical upright as on a horizontal crosspiece.
  • the oblique arrangement of its pivot axis has the effect that its free end, placed outside the path of the leaf in its rest position, intercepts this trajectory when the arm has been sufficiently spaced from its rest position.
  • stop arm Since the stop arm has only one degree of freedom, it is easy to place it in an appropriate manner so that the opening of the leaf causes the element to engage on the free end of the arm and therefore the complete immobilization of the latter.
  • the pivot axis of the stop arm and said perpendicular to the joint plane define a plane substantially parallel to the leaf and to the standing frame.
  • pivot axis of the stop arm and said perpendicular to the joint plane define a plane substantially orthogonal to the leaf and the frame.
  • the window opener shown in Figure 1a consists of a part 1 fixed on the lower cross member T of the window frame and a keeper 2 fixed on the opening frame or leaf C of the window.
  • Leaf C opens from right to left in Figures 1a and 1b, the hinges, not shown here, being on the left.
  • Part 1 comprises an elongated base 3 fixed to the cross-member T for example by screws 4 and a stop arm 5 pivotally mounted at one end on the base 3. In the rest position, the arm 5 is placed on the base 3 and is substantially parallel to the joint plane P defined between the cross member T and the leaf C.
  • the invention is not limited to the value indicated above for the angle A.
  • the value of A must be determined at the same time as the length of the stop arm 5 so as to obtain the effect explained above. In practice, however, the angle A will be between 10 and 20 °.
  • the arm 5 is bent and comprises two portions 7 and 8.
  • the portion 7 directed perpendicular to the pivot axis aa, is received in a housing 9 formed in the base 3.
  • the pivoting assembly is produced by providing the portion 7 with two pins, not visible in the drawings, which are engaged in suitable holes.
  • the portion 8 which extends the portion 7 forms with it an angle equal to the angle A, that is 15 °.
  • the end 6 which ends the portion 8 is projecting and carries ribs 10, 10 'on its two faces, which ribs form an angle A with the pivot axis of the arm 5.
  • the ribs 10, 10' are extended by elements 11, 11 'bent outward.
  • the arm 5 has, over its entire length, reinforcing ribs 12, the ribs 10, 10 'of which constitute the extension.
  • the role of the ribs 10, 10 'and the elbow elements 11, 11' is to allow a locking connection of the arm 5 with the keeper 2, as will be explained below.
  • the keeper 2 fixed on the leaf C is provided with an opening 15 placed so as to be opposite the end 6 of the stop arm when the latter has been put in the stop position.
  • the edge 16 of the opening 15 located on the side of the rest position of the arm 5 is inclined relative to the perpendicular to the joint plane by an angle substantially equal to the above-mentioned angle A, ie 15 °.
  • A ie 15 °.
  • the corresponding wall on the left in the drawings
  • this groove is surmounted by a recess 18 which, unlike the groove 17, does not extend until opening on the face of the keeper 2 but is closed by a wall 19.
  • the groove 17 and the recess 18 are in accordance to receive respectively the rib 10 and the bent element 11 of the arm stop 5.
  • the keeper 2 comprises a part 20 comprising a tongue 21 which largely closes the opening 15 and whose edge is parallel to the abovementioned edge 16.
  • the part 20, which can be fixed to the main part of the keeper by a screw 22 also used for fixing the keeper to the leaf C, is sufficiently flexible so that the tongue 21 deviates elastically from its natural position when it is re pushed by the end 6 of the stop arm.
  • the part 20 also includes an outer portion 23, perpendicular to the tongue 21, on which one can act to trigger the unlocking, as we will see.
  • the stop arm is first of all pivoted by an appropriate angle to the position shown in FIGS. 1b and 2b, the leaf C then being closed.
  • the leaf When the leaf is opened, the keeper 2 comes into contact with the free end 6 of the arm and more particularly, the tongue 21 comes into contact with the rib 10 and flexes. The end 6 can thus penetrate further into the opening 15 of the keeper. This allows the rib 10 'located on the other side to be housed in the groove 17, and the elbow 11' to be housed in the recess 18.
  • FIG. 4 A second embodiment of the invention is shown in Figures 4 to 6.
  • the pivot axis a'-a 'of the stop arm 105 shown in phantom in Figure 4 is always inclined d 'an angle A with respect to the perpendicular to the joint plane, but the plane defined by the pivot axis a'-a' and said perpendicular is this time perpendicular to the general plane of the window.
  • the inclination of the pivot axis simply results from the inclination of the base 13 on which the arm 105 is pivotally mounted.
  • the base 103 has a substantially triangular section or trapezoidal with an angle A between its upper face and its base A being here 15 °.
  • the rib 110 is parallel to the pivot axis of the lever 105, contrary to the arrangement of the first embodiment.
  • the pivot axis a'-a ' having its projection in the plane of the window merged with the perpendicular to the joint plane, it becomes possible to produce the keeper 102 symmetrically so that it can be placed indifferently on a right leaf or left leaf.
  • FIG. 5 It can be seen in FIG. 5 that the keeper 102 has a plane of symmetry S.
  • the tongue 121 of the part 120 has its edge perpendicular to the plane S, and the edge 116 of the opening 115 comprises two sections which make the same small angle with the perpendicular to the plane S and which connect to the plane S. It is the same for the bottom of the groove 117 and the recess 118 which is closed at its two ends by walls .
  • This embodiment therefore allows an advantageous reduction in the number of parts to be manufactured and stored.
  • the embodiment shown in FIG. 7 is particularly suitable when it is desired to use metals as constituents of the various elements.
  • the stop arm 205 has at its free end a lumen 210 and the keeper 202 has on one at least of its sides a stud 215 which engages in the lumen 210 when coming into contact. from the end of the stop arm with the keeper.
  • the keeper has two pins 215 and thus has a plane of symmetry as was the case for keeper 102 in FIG. 5.
  • the keeper shown in Figure 8 is of the same type as that of Figure 7 but it is provided with a locking device and has no plane of symmetry.
  • FIG. 8 the substantially trapezoidal shape of the stud 215.
  • the part 220 carrying the tongue 221 is pivotally mounted on an axis 224 and recalled by a spring 225 mounted around the axis 224 and bearing on the upper wall of the keeper by a part 226 opposite to that in contact with the tongue.
  • This axis is carried by a U-shaped piece 227 resting on the bottom 228 of the keeper.
  • This part 227 is movable in the direction of the arrow, before tightening the screws 222, for adjusting the operating clearance.
  • a locking device comprising a bolt 230, actuated by a bolt 231, which can advance under the tongue 221 can prevent its bending. It is thus possible, once the engagement of the strike on the stop arm has been made, to close the lock. The window is then locked in its ajar position. Such an arrangement would be useful, for example in schools where children should not be able to close or open the windows themselves.
  • the device is installed either on horizontal crosspieces or on vertical uprights. In addition, it occupies a very small width and can be placed on very narrow profiles. The relatively large clearance which may exist between the base and the keeper also facilitates the positioning of the fixing screws.
