Definitions

  • the invention relates to a locking fitting for a sliding leaf. This invention will find its application in the industry specialized in the field of building hardware.
  • a locking fitting is known for a sliding opening through document EP-A-0.341.174 belonging to the state of the art referred to in article 54 paragraph 3 of the European Patent Convention insofar as it benefits a priority date prior to that of this patent application when it has only been published at a later date.
  • This document can only be taken into account for the assessment of novelty and not of inventive step vis-à-vis the present invention.
  • this locking fitting for a sliding leaf is also provided with a device for locking the control handle in the unlocked position, this locking device consisting of means making it possible to offset the pivot axis of said control handle by during manipulation of the locking fitting to modify the direction of rotation of this handle under the action of elastic return means.
  • control handle is formed by a radial wing at the top of which there is a circumferential wing while at its lower end, this radial wing is provided with a semi-cylindrical bead fitted into a vertical groove arranged in the interior angle of the angle iron forming the base.
  • the vertical groove provided in said base is intended to allow a certain mobility of the semi-cylindrical bead in particular in a direction parallel to the plane of the opening.
  • a connecting rod comes to connect the control handle to the base.
  • said connecting rod comes to act on the handle so that its semi-cylindrical bead comes to move in the groove of the base in a direction parallel to the plane of the opening.
  • the present invention as defined in claim 1 is new compared to the state of the art corresponding to document EP-A-0.341.174 in that the control handle is pivotally mounted on the base around an axis fixed swivel.
  • the locking fitting comprises means for moving the point of application of the elastic means on the control handle to ensure the constant return of the latter in the locking position.
  • this locking fitting according to the invention is its versatility. Indeed, thanks to appropriate means, it can alternatively be either automatic or semi-automatic, thus adapting to any type of door, window or the like. This standardization has also made it possible to achieve a simplification of the component parts of the locking fitting, both in terms of their number and in terms of their design.
  • the locking fitting 1, object of the present invention, and shown in Figures 1, 2 and 4, is more particularly intended for doors, windows or the like whose opening is of the sliding type.
  • this locking fitting 1 is composed of a base 2, fixed to the wall on the internal face of the front upright of the sliding leaf and on which is mounted, pivotally, a control handle 3.
  • the latter is provided with a locking member 4 intended to cooperate with a keeper 5, disposed on the frame of the door, window or the like.
  • the base 2 is formed by an angle iron comprising a wing 6, attached to bear on the internal face of the opening leaf and a projecting wing 7 disposed perpendicularly to the plane of the latter.
  • a groove 9 in which is housed a semi-cylindrical bead 10 secured to the control handle 3 and constituting the axis of rotation of the latter.
  • said control handle 3 is formed by a radial wing 11 comprising, on one of its vertical edges 12, said semi-cylindrical bead 10.
  • the locking member 4 integral of the latter, it is formed by a blade 15 depending on the radial wing 11 and comprising, at its free end 16, a spout 17 capable of cooperating with a hook-shaped element 18 such as a keeper 5 disposed on the amount of the door frame, window or the like.
  • the locking fitting 1 further comprises elastic means 19 capable of pushing the control handle 3 alternately, either in its locking position 20, as shown in the figure 1, or in the unlocked position 21 corresponding to the configuration of said control handle 3 shown in FIG. 2.
  • these elastic means 19 consist of an elastic element 22 connected, at one of its ends 23, to the projecting wing 7 of the base 2, the other end 24 of this elastic element 22 being fixed to the radial wing 11 of the control handle 3.
  • the arrangement of the elastic element 22 is determined so that its connection points 25, 26 respectively on the base 2 and the control handle 3, are able to align with the axis of rotation of the latter, consisting essentially of the semi-cylindrical bead 10 during the pivoting of said control handle 3.
  • this elastic element 22 passes through an unstable equilibrium position in which the different forces present cancel each other out. On either side of this point of equilibrium, this elastic element 22 causes the control handle 3 to rotate in different directions.
  • connection point 25 of the elastic element 22 on the base 2 is immutable when the locking fitting 1 is ordered, only the connection point 26 is subjected to an angular displacement equivalent to that effected by the control handle 3. Therefore, when ordering it, this connection point 26 must, necessarily, cut, during its movement, the segment 27 connecting the connection point 25 to the pivot axis of the control handle 3, this segment 27 materializing the line of balance of forces.
  • connection point 26 when said connection point 26 is positioned on said segment 27, between the connection point 25 and the pivot axis of the control handle 3, the elastic element 22 is in an unstable equilibrium position.
  • the distance 28 separating the connection points 25, 26 tends towards a minimum, corresponding to maximum compression of the elastic element 22.
  • this distance 28 tends to increase when said connection point 26 moves in one or the other direction relative to the segment 27.
  • the elastic element is represented in the form of a leaf spring. However, it can be envisaged to replace this spring with any other elastic element capable of fulfilling identical functions, such as a helical spring or the like.
  • connections of the elastic element 22 with the projecting wing 7 of the base 2 and the radial wing 11 of the control handle 3 are formed by articulation means 29.
  • This characteristic has, essentially, for function of reducing the local stresses on the elastic element 22 during the manipulation of the locking fitting 1. It is observed, in fact, that in the case of a rigid connection, this elastic element 22 is highly stressed, in particular at its ends 23, 24.
  • the locking fitting 1 comprises means 30 making it possible to move the point of application of the elastic means 19 on the control handle 3.
  • the objective of such means 30 consists in proposing to the use a standard locking fitting, the operating characteristics of which can be modified without great difficulty and without requiring any change of parts.
  • these means 30 allow the automatic locking characteristic to be restored to the locking fitting by ensuring the systematic return of the control handle 3 to the locking position. This is done by a simple displacement of the connection point 26 of the elastic element 22 on said control handle 3. More specifically, these means 30 are constituted by a connection point 31 of the elastic element 22 on the wing radial 11 of the control handle 3, the position of which is determined so that, in no case, during the rotation of the latter, does it cross the segment 27 connecting the connection point 25 at the level of the base 2 and the axis of rotation formed by the semi-cylindrical bead 10.
  • this connection point 31 is located in the interior angle 32 formed by the radial wing 11 and the circumferential wing 13. However, it can be chosen a completely different arrangement for this connection point 31 while respecting the condition expressed above.
  • the end 24 of the elastic element 22 is connected to the control handle 3 at this connection point 31 by means of articulation means 33.
  • the present locking fitting 1 is of a particularly simplified design, which obviously has repercussions on its cost price.
