Abstract

The lock, made with a fastener (7) that projects to engage with a lever connected to the fixed frame and retracts to hold it in place, has an inner bracket (24) which operates the door or window long bolts and the fastener. The bracket has a first drive lug (27) engaging with a drive pin linked to the lock nut (16) and a second lug interacting with a cam surface on the fastener's shank.

Description

The invention relates to a door and window interlock lock or the like, comprising, housed in a housing, a mechanism for control provided capable of pushing back, from an erased position in this case in a projecting position relative to the edge before the latter and vice versa, a fastening member to even to cooperate with a crank lever, this mechanism order comprising, on the one hand, at least one follower and, on the other hand, an easel provided capable of being made integral an operating rod corresponding to a lever or lever lock for controlling the erasure of said attachment member under the impulse of said operating rod during a displacement of the latter in a determined direction, including unlocking.

The present invention relates to the field of hardware building and relates, in particular, to crackers of doors, windows or the like.

It is known, in particular from document FR-A-2.734.015, a door, window or the like in the form of a lever, one end of which is articulated, by means of a support, in the rebate of the front upright of the frame sleeping. Thus, this lever can pivot around a parallel axis in the plane of said door or the like, either perpendicular to the front pillar of the sleeping frame. By the way, the end opposite of this lever is able to cooperate with an organ maneuverable hooking by means of a button control and mounted in a box at the front upright opening correspondent.

More specifically, the command button acts, by via a maneuvering square, on a locator in said housing provided capable of being embedded in the edge before opening it. So, under the influence of the rotation of the control button, the follower attacks the latching member, more particularly in the form of a bolt, which then comes move in the plane of the opening so as to present itself, as the case may be, in the projecting position or in the retracted position by report to the front song of this opening.

It is specified in this document that in case of equipment of opening a cremone bolt or bolt lock, comprising a headrest extending over the entire height of this edge before the opening, the housing of the ajar lock can be returned in solidarity with this headrest, the latter also comprising a opening allowing the passage of the bolt corresponding to the organ hooking.

This is of rectangular section and has a narrowing in its part likely to appear protruding from the edge before the opening. So, when this attachment member cooperates with the end of the lever, more precisely when its protruding part is engaged in the oblong opening made for this purpose in this end of the lever, it performs the function of a button in a buttonhole. Under these conditions, when activating the ajar, the fastening member and the oblong opening are in the same vertical alignment. Then, half-opening opening it, the lever swings around its pivot axis, while its free end with the oblong light pivots around the constriction corresponding to the attachment member. This one no longer in the extension of this oblong opening said lever, it can only be removed voluntarily, either by direct action on this lever or on the organ hooking.

It will be noted that if such a cracker is, ultimately, very discreet, in the sense that all of their elements is likely to take a position in a notching of the sash and in the rebate of the frame and if they can be made active very easily, they are not no less restrictive to the command to open an opening, in particular when the latter is otherwise provided with a multi-point locking hardware, such as a lever or lock-bolt.

It is understood, in fact, that when the opening of a door or window has been closed on its sleeping frame and that through the cremone bolt control mechanism or cremone bolt has been brought into the locking position, this spacer is no longer of any use and there is no point in it being kept active. In this regard, if, when locking the door or window the user, having previously activated the opener, omits to deactivate it, it is very likely that he will also forget it when he seeks to open, to new, that door or window. Also, he will never go probably account that through an attempt to open of the opening which will ultimately be prevented beyond a race corresponding to the range of motion allowed the door guard. Being necessarily taken by surprise, it strong risk of giving a brutal shock to the sash when entering in action the opener, which not only has the consequence of soliciting, strongly, the parts of this but also carpentry. By the way, this represents a risk of accident for this user who, himself, may abut the sash, normally expecting a opening without resistance.

In this regard, it is also known from document DE-198 15 671 a locking fitting, of the lever type, comprising a main mechanism for action, in particular by via a handle, on an operating rod extending to the back of a headrest. Through this mechanism main command it is possible to work on a bolt turn around and on a hook bolt. At the back of the headrest is still reported the housing of a crank lock.

This includes a locking member whose tail extends into this case, while the head in the form of mushroom is provided capable of emerging from the aforementioned headrest, this through an appropriate opening.

• une première rétractée par rapport à la face avant de la têtière ;
• une deuxième où il coopère avec un loquet d'entrebâilleur ;
• et une troisième dans laquelle il vient finalement s'insérer dans l'ouverture d'une gâche sur le dormant.

Thus, this locking member can occupy three distinct positions:

• a first retracted with respect to the front face of the headrest;
• a second where it cooperates with a crank latch;
• and a third in which it finally fits into the opening of a strike on the frame.

In particular, the mechanism of this crank lock includes a follower on which a spring acts allowing keep the handle, as appropriate, in an upright position lock or in a horizontal unlocked position. This follower also has a cooperating control finger with a notch in the tail of the organ of locking, knowing that in the locked position the end of this control finger is located in the extension of a plane stop preventing said locking member from being able to be pushed back, by direct action on the latter, in a position retracted. Said mechanism also includes a mounted lever articulated in its housing and comprising a first arm of which the end cooperates, just like the tail of the organ of locking, with the follower control finger. It is still provided with a second arm, the end of which is suitable, when the air lock is activated, be located on the trajectory of a coach associated with the operating rod.

More precisely, through this coach and starting from a locking position of said operating rod while the ajar is active, it can be brought into a inactive position, by action on said lever, when it is commanded the unlocking of the lever or lever-bolt. In this case the trainer acts on the second arm of this lever whose end of the first arm controls the rotation of the follower and, thereby, the removal of the organ from locking.

Conversely, when the ajar is made active while the cremone bolt or locking bolt is unlocked, it can be obtained the lock of the latter without there being an interaction on this ajar, the coach of which is equipped with the operating rod being liable to fade, elastically, in front of the end of the corresponding second arm to the lever.

Description of the prior art document which above, it appears that the coupling means which are provided able to cooperate with the operating rod control erasure of the locking member or latching member by action, exclusively, on the lock follower door guard. We understand that to order this rotation and, through it, the recoil of the organ attachment, apply a torque not negligible if we take into account, in particular, the weak arm lever provided by the drive finger relative to the axis of rotation of the follower.

We also know, from document EP-0 823 521, a lock of the bracing device associated with a locking fitting, of the type cremone bolt or bolt lock. This one has a mounted easel integral in translation with an operating rod and which, starting from a locking position of the latter, is able to control the removal of the fastening member from this crank lock, when unlocking command said cremone bolt or bolt lock. More specifically, this easel is provided with a control finger moving in a light in the shape of an inverted bottle, internally to the crankcase lock housing, the tail a fastening member.

This lock also includes declutching means which prevent any action on the attachment member by the bridge in the event of movement of the operating rod from a position unlocked towards a locked position. Sure the tail of the latching member is also able to act a follower. More particularly, in the lower part of said tail has a toothing on which comes to mesh teeth corresponding to the follower.

Finally, the design of this crank lock allows again to make active, i.e. to command the advance of the fastening member directly by action on the mechanism control of the lever or lever-bolt. So, starting from a lock position and assuming the lock is still inactive, a first order of unlocking generates the advancement of the fastening member. he then agree to lock and unlock the door by action on the lever or lever-lock for cause it to recede.

In fact, the invention relates to a crane lock, door, window or the like, comprising, housed in a housing, a control mechanism provided capable of repelling, from a position erased in this housing in a projecting position relative to the edge before the latter and vice versa, a fastening member capable of cooperating with a lever for the stay, said control mechanism comprising, on the one hand, at least one follower and, on the other hand, a bridge provided adapted to be made integral with an operating rod corresponding to a cremone bolt or locking bolt to control the erasure of said fastening member under the impulse of said operating rod during movement of the latter in a determined direction, in particular unlocking, characterized in that:

• said bridge comprises a first drive pin capable of acting on a drive finger associated with the follower and a second drive pin provided capable of cooperating, beyond a stroke, with a track of a cam corresponding to a driver associated with the tail of the latching member under the impulse of the operating rod when the latter moves in said determined direction, in particular for unlocking;
• said drive pins are provided of retractable type, respectively, relative to said drive finger of the follower and to the coach's cam, in the context of a relative movement of these elements relative to each other, during movement in the opposite direction of said operating rod, in particular for locking.

In short, this solution according to the invention makes it possible to act directly on the hooking member of a crank lock through a cremone bolt or locking bolt. In fact, this action on the fastening member occurs beyond of a first race, which allows, as will appear further on, to keep the safety function through which the fastening member, abutting against the finger control of the follower, cannot be pushed back by action direct inside the lock case.

Finally, it follows from the present invention a particular ease of control of the lever or lever-bolt likely to act on this crank lock.

As shown in Figure 1 of the accompanying drawings, the present invention relates to the field of doors, windows or the like and, more particularly, at a crank lock 1 capable of fitting in particular opening it from such a door, window or other 2.

Thus, such a stay lock 1 comprises, housed in a case 3 taking position, for example, in a notch provided for this purpose in rebate 4 of the opening 5, a mechanism for control 6 provided capable of repelling a fastening member 7 in an erased position inside the housing 3 or, at otherwise, in a position, as visible in Figure 1, projecting at this rebate 4 of the opening 5.

In this projecting position, this hooking member 7 is designed to cooperate with a lever for the stay 8 arranged in correspondence on the sleeping frame 9 of this door, window or other 2.

In this regard, particular reference is made to the document FR-A-2.734.015 for more details on the operation of a like a cracker.

To return to the subject of the present invention, the lock advantageously, means 1 coupling 10 of its control mechanism 6 with a operating rod 11 (more particularly visible in the Figures 2 to 4) corresponding to a bolt or bolt lock 12 that is fitted to the opening 5 of the door, window or the like 2.

In fact, these coupling means 10 are intended to ensure the erasure of the attachment member 7 of this lock spacer 1 under the impulse of said operating rod 11 when moving the latter in one direction determined, more particularly, but not exclusively, to unlocking 13.

Furthermore, they cooperate with declutching means. 14 designed capable of disengaging said means coupling 10 relative to the control mechanism 6 of the lock 1, under the effect of the displacement of this rod maneuver 11 in a reverse direction 15, in particular of locking.

Going back to the lock control mechanism 6 spacer 1, this comprises, housed in the housing 3, a follower 16 on which a button can rotate 17, visible in Figure 1, through a square operating 18.

This follower 16 has a first drive finger 19 provided able to cooperate with the tail 20 extending in the housing 3 of the fastening member 7 so as to push it back in a projecting position relative to the rebate 4 of the opening 5 and therefore capable of cooperating with the lever to ensure its erasure in said housing 3.

Note and as visible in Figures 2 and 3, in this protruding position of the hooking member 7 the finger drive 19 comes to cooperate, through its end free, with a stop plane 21 formed at the level of said tail 20 of this fastening member 7, so as to oppose a action which would be exercised directly on the latter with the aim to push it into the housing 3, that is to say in a inactive position.

Before continuing the description, it should be noted that the housing 3, as visible in Figures 2 to 4, can be secured to a headrest 22 capable of extending over the whole rebate height 4 of the opening 5, such that represented in FIG. 1. As for the operating rod 11, it is provided able to circulate at the rear of this headrest 22, in particular between the latter and the housing 3 of the lock of the brace 1. Such an operating rod 11 comprises, for this purpose, oblong openings for passage fixing means 23 of the housing 3 on said headrest 22 and the passage of the fastening member 7.

As for the coupling means 10, they consist, substantially in a transmission organ more particularly an easel 24, mounted movably in the housing 3 parallel to the operating rod 11 and provided capable of being made in solidarity with the latter through one of its ends 25. At its other end 26, this easel 24 comes cooperate with the follower 16 for, under the impetus of said operating rod 11 in the unlocking direction 13, ensure the rotational drive of this follower 16 and the recoil of the fastening member 7.

More particularly, through this end 26 of the bridge 24 it is ensured, during this displacement of the rod of work 11, a preliminary rotation of the follower 16 on an angular stroke allowing the release of the finger drive 19 relative to the abutment plane 21 of the tail 20 of this fastening member 7. Also, at this end 26 the easel 24 has a drive pin 27 provided adapted to act on a second drive finger 28 associated with said audit follower 16.

Under these conditions and starting from the active position, therefore protruding from the fastening member 7, the displacement of the easel 24 under the impulse of the operating rod 11, this in the unlocking direction 13, leads to a rotation preliminary of follower 16 through said lug 27. In fact, this easel 24 still has a second drive pin 29 provided capable of cooperating, beyond a race 30, with a track 31 of a cam 32 corresponding to a trainer 33 associated with the tail 20 of the attachment member 7.

More particularly, starting from the position illustrated in the Figure 3, if the drive pin 27 is provided capable of attacking directly the second drive finger 28 of the follower 16, the second drive pin 29 is unable to exercise its action on track 31 of cam 32 only beyond a stroke 34 defined. Consequently and as already indicated above, the drive finger 19 of the follower 16 has previously been clear of the abutment plane 21 otherwise preventing the recoil of the attachment member 7 by direct action on the latter.

It has already been specified that these coupling means 10, constituted, substantially, by the easel 24, cooperated, moreover, with declutching means 14 designed capable of disengage these coupling means 10 under the effect of the displacement of the operating rod 11 in a opposite direction, i.e. in the direction of lock 15.

Substantially, these declutching means 14 consist of drive pins, respectively 27 and 29, associated with easel 24 and retractable type with respect to, respectively, the second drive finger 28 of the follower 16 and the cam 32 of the coach 33, this within the framework of a relative displacement of these elements relative to each other in this locking direction 15, ie starting from the position of the easel 24 as shown in Figure 2 to reach the position corresponding to figure 3.

According to an advantageous embodiment, in particular visible Figures 6 and 7, these drive pins 27, 29 are rendered secured to elastic means 35, 36 of positional reminders active, i.e. able to cooperate, as appropriate, with the second drive finger 28 of the follower 16 or the cam 32. These drive pins 27, 29 are still beveled, at least on one side 37, 38, so as to allow them to be repelled in an inactive position, i.e. deleted, under the pulse, respectively of the second drive finger 28 and of cam 32, in the context of a relative displacement of the easel 24, secured to the operating rod 11, in a direction 15, more particularly for locking the cremone bolt or bolt lock 12.

Conversely, these drive pins 27, 29 also include a stop plane 39, 40 for repelling the second finger 28 of the follower 16 or the coach 33 to across track 31 of cam 32, when these elements are find on their way when ordering on the move easel 24 driven by the operating rod 11 in unlocking direction 13.

In short, it is the passage from the visible situation in the Figure 3 to that shown in Figure 2, knowing that in a configuration as shown in Figure 4, it is say gap lock 1 disabled and lever or lever bolt unlocked, the coupling means 10, defined by the bridge 24, are somehow disengaged, therefore disconnected of the control mechanism 6 of the crane lock 1. In sum, in this position the displacement command of the operating rod 11, therefore of the easel 24, has no consequence on this control mechanism 6, whatever the unlocking 13 or locking 15 direction taken by this operating rod 11.

According to the invention also, this crank lock 1 can be provided with indexing means 41 of the angular positions 42, 43 of the follower 16 corresponding to the active and inactive position of this crane lock 1. Such indexing means 41 are defined according to a preferred embodiment, on the one hand, by a housing 44 in the housing 3 provided, at its peripheral wall, of recesses 45 in which is able to engage, elastically and in angular positions mentioned above, at least one indexing boss 46 which, on its periphery, said follower 16. In this regard, this follower 16 can be made of synthetic material, while said indexing boss 46 is advantageously positioned on a elastic blade 47 drawn on this periphery of said follower 16.
