Definitions

  • the invention relates to a locking fitting for sliding doors comprising: - A base formed by an angle iron, one wing of which is attached to the internal surface of the opening leaf and the other wing of which is protruding from the latter; - A control handle pivotally mounted on said base and comprising a locking member intended to cooperate with a keeper or equivalent disposed on the frame.
  • the present invention relates to the industry specialized in the field of building hardware.
  • this locking fitting comprises a base that comes to bear on the internal face of the front upright of a sliding leaf.
  • This base supports a control handle to which is fixed a locking member cooperating with a keeper, disposed on the frame of the door, window or the like, when the latter is closed.
  • the base is constituted by an obtuse angle angle, one wing of which is attached, by means of fixing elements such as screws, rivets or the like, to said internal face of the front upright of the opening, l other wing projecting from the plane thereof.
  • a vertical groove for accommodating a semi-cylindrical bead, integral with the control handle, and constituting the means of rotation of the latter.
  • said handle control it is formed by a radial wing comprising on one of its vertical edges the aforementioned semi-cylindrical bead.
  • a curvilinear wing called circumferential, due to its arrangement and its displacement relative to the pivot axis formed, substantially, by said semicylindrical bead.
  • the locking member cooperating with the keeper disposed on the frame, is in the form of a blade fixed on the radial wing of the control handle and having an end in the form of a spout capable of coming into contact with a design element identical to a hook constituted by the keeper.
  • This known locking fitting is also provided with elastic return means of the control handle in the locked position, which gives said fitting an automatic nature by systematically locking the door, window or the like in the event of closing. of the opening.
  • These elastic return means consist of a pre-stressed helical spring disposed between the projecting wing of the angle iron forming the base and the radial wing of the control handle.
  • the user causes the compression of this helical spring and the release of the locking member from its corresponding keeper.
  • the release of the control handle releases these elastic return means bringing the locking fitting back into its locked position.
  • an untimely operation of the opening executed, for example, by a child, can cause the locking of the door, window or the like, and order the user who has just crossed the open leaf to stay outside the house.
  • This locking device consists, on the one hand, of a groove, of oval section, in which is engaged the semi-cylindrical bead of the control handle so as to allow a perpendicular movement of the latter relative to its pivot axis .
  • a cavity capable of receiving a boss present on the underside of the circumferential wing forming the gripping element. the control handle.
  • This locking device is completed by the elastic return means of the control handle in the locked position, these means also exerting a radial action on said control handle to ensure the transverse movement of the latter relative to its axis. of rotation.
  • the advantage of this radial action of the elastic return means consists in bringing the aforementioned boss of the circumferential wing into the corresponding cavity and, finally, maintaining the control handle in the unlocked position.
  • Such a locking device requires, after unlocking the door or other, the intervention of the user to release, again, the control handle, the latter then resuming, its locked position under the action of the return means elastic.
  • the elastic return means with radial action, have a specific, non-standard configuration, due to their action on the control handle, on the one hand, to bring it back into the locked position and, on the other hand, to give it a movement transverse to its pivot axis.
  • this blocking device proves to be unreliable and totally ineffective in the event of fatigue of the elastic return means. Indeed, it is found that only their radial action ensures the locking of the control handle in the unlocked position. However, these same elastic return means exert, simultaneously, a pressure on said control handle tending to dissolve the connection, boss-cavity, this action being, therefore, completely antagonistic to the previous one.
  • a device for blocking the control handle in the unlocked position is only useful in the context of sliding doors allowing the user to leave the dwelling. This is not the case, in particular, for upstairs windows giving access to no terrace. Consequently, for such openings, it is preferable to keep the automatic appearance of the locking fitting and to proceed with the removal of the device for locking the control handle in the unlocked position.
  • the object of the present invention is to remedy the aforementioned drawbacks by proposing a locking fitting comprising a device for locking the control handle in the unlocked position which is particularly reliable and which necessarily requires: the intervention of a user to return said control handle to the locked position.
  • the object of this invention is to standardize the equipment involved in one or other of the conditions of use of these locking fittings for sliding doors, namely: - automation with systematic return of the control handle to the locked position; - or semi-automatic system offering the possibility of also maintaining said control handle in the unlocked position.
  • the invention solves the problem of creating a locking fitting for sliding doors comprising: - A base formed by an angle iron, one wing of which is attached to the internal surface of the opening leaf and the other wing of which is protruding from the latter; - A control handle pivotally mounted on said base and comprising a locking member intended to cooperate with a keeper or equivalent disposed on the frame.
  • This locking fitting further comprising unique elastic means capable of pushing back the control handle, either in its unlocked position, either in the locked position, according to the angular offset conferred on said control handle.
  • 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 be, alternatively, either automatic or semi-automatic, thus adapting to any type of door, window or the like. This standardization has also made it possible to simplify the constituent 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 with 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.
  • This transition from the elastic return of the control handle 3 to the unlocked 21 and locked 20 position can be ensured either at the start or at the end of rotation of the control handle 3 or even when the latter has reached a median angular position. It depends on the objectives sought by the manufacturer and, in particular, market requirements. Thus, when this transition takes place at the start of manipulation of the control handle 3, preference is given to the safety side of the locking fitting 1 by ensuring, almost systematically, the maintenance of the control handle in the position of opening when the door is unlocked. Otherwise, priority will be given to the automation of the locking fitting 1 while offering the possibility of maintaining the control handle 3 in the unlocked position by giving the latter a maximum rotation.
  • the elastic element is represented in the form of a leaf spring.
  • this spring can be envisaged to replace this spring with any other elastic element capable of fulfilling identical functions, such as a helical spring with the analog.
  • 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.
  • this elastic element 22 is highly stressed, in particular at the level from 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 whose operating characteristics can be modified without great difficulty and without requiring a change of parts.
  • these means 30 make it possible to restore its locking characteristic to its automatic characteristic 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 26 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 has a particularly simplified design, which obviously has repercussions on its cost price.
