Abstract

The system consists of a housing (2) containing a control mechanism (3) with an actuator (4) for one or more long bolts (5, 5A) and a key-actuated component (12) which governs a locking mechanism (13) holding the long bolts in their locked position. The locking mechanism comprises a catch (14) which is operated by the key-actuated component to cooperate in its locked position with a rack (15) associated directly or indirectly with the long bolts.

Description

The invention relates to a lock-bolt for door, French window or the like, comprising, housed in a housing, a control mechanism comprising, on the one hand, means manual and / or automatic actuation of at least one operating rod capable of acting on one or more organs of locking intended to cooperate with one or more keepers and, on the other hand, a key element for controlling a bolt frame and means for blocking the rod (s) operation in the locked position.

The present invention will find its application in the field of the building hardware and concerns, more especially locks and bolts.

Of course, we already know a number of locks and bolts corresponding to the above description, see by example EP 0 341 173 A on EP 0 581 338 A.

Thus, such a lock and bolt for door, window or similar, has a housing mounted on the sash and accommodating a control mechanism on which the user can intervene via a key element and, frequently, a handle or a control button.

Also, such a control mechanism includes means manual and / or automatic actuation of at least one operating rod extending above and / or below of said housing and capable of acting on one or more organs of locking intended to cooperate with keepers located in correspondence on the sleeping frame of said door or window. It should be noted, in this regard, that the rods of operation of such a lock-bolt can be mono or bidirectional, i.e. the operating rod extending above and that arranged below the housing may have to move in the same direction to to switch from the unlocking position to the lock, just like their movements can be reversed driven by the control mechanism.

As for the means of actuation of this or these rods of maneuver, they usually consist of a handle or control button acting on the operating square of a follower which cooperates, either by a toothing or by a control finger, directly or through a easel, on said maneuvering rod (s). We will observe that, in a known manner, such a handle or command button can still act, via a same double-decker nut, on a return latch bolt elastic in locking position. In this regard, it is also common to get the follower to cooperate with elastic return means making it possible to recall, systematically, the handle or the control button in its initial position after locking operation or unlocking of the operating rod (s) or of the turn around.

In order to increase the safety of such bolts and locks avoid, in particular, that we can push back the the operating rods from their locking position towards their unlocked position, this by a direct action on the locking members controlled by this or these operating rods, such a bolt-lock comprises, in in addition, means for blocking this or these in locked position, such blocking means being controlled by the key element.

In this regard, these blocking means are frequently consisting either of a deadbolt suitable for being controlled by this key element, either by an organ directly associated with this deadbolt.

Either way, in either case it is neither more and less, a locking finger which, under the impulse of the key element, is able to position itself in a light or a cutout in the easel or in a operating rod. In fact, this cooperation is not possible only when the operating rod or rods are brought into their fully locked position, which leads to position the cutout or light in the easel or said rod to the right of said locking finger.

In the end, we realize that it is imperative that the or the operating rods have been suitably previously locked otherwise the aforementioned locking means do not can be activated. However, it is not uncommon for this maneuver cannot be fully executed, for example due to a defective adjustment or wear of the keepers so that at in turn, said blocking means cannot be activated.

In this context, the user has no other solution for lock the door when at home when operating the key item.

On this it should also be noted that there exists, at the time current, locks and bolts often qualified as semi-automatic, with elastic means for automatically recall the operating rods in locked position as soon as the door or window is closed on the sleeping frame. Unlocking is obtained manually, by action, just as before, on a handle or a control button from which results, for elsewhere, the resetting of the elastic return means.

One of two things, these elastic return means have a high stiffness coefficient to systematically and fully the operating rods in their position of locking, which has the consequence of generating a noise of high functioning besides the maneuver of unlocking is made harder, or these means of elastic booster are determined to be barely sufficient for perform the function assigned to them as soon as the constraints encountered by the operating rod (s), especially at the time of the engagement of their lock in the corresponding strikes, are not too high. In fact, otherwise, such means of elastic recalls often lead to the operating rods in an intermediate position, between their position of lock and their unlock position. Note that the control handle through which unlocking can, under these conditions, be used to bring, manually, these operating rods at the end of the race locking. Finally, this manual operation, the user does not will carry it out that when he wishes to secure, perfectly, his door or window, especially during a departure extended from his home. In other situations, it may perfectly content with a lock resulting from a partial engagement in the keepers of the locking members controlled by the operating rod (s).

However, it is obvious that by equipping such locks and bolts semi-automatic locking means for the rod (s) maneuver corresponding to a design as described more high, the user will almost always have to activate, via the control handle, the operating rods to ensure that they are beautiful and well in their fully locked position before order the item with a key.

In fact, the present invention proposes to provide a solution to the aforementioned problem this through a lock-bolt allowing a lockout and therefore a blocking of the operating rods with regard to an action tending to return them to a locked position, which whatever the position occupied by these operating rods between, precisely, unlocking and locking. In ultimately, the present invention offers the possibility of perfect the locking resulting from the deadbolt, so increase safety, even with low commitment from locking members in their keeper.

To this end, the invention relates to a locking lever for door, French window or the like, comprising, housed in a housing, a control mechanism comprising, on the one hand, manual and / or automatic actuation means of at least one operating rod capable of acting on one or more organs of locking intended to cooperate with one or more keepers and, on the other hand, a key element for controlling a bolt frame and means for blocking the rod (s) operation in the locked position, characterized by the fact that the locking means of the rod (s) consist of a locking pawl which, under the impulse of the key element, is designed to cooperate, in the locked position, with a rack directly or indirectly associated with the or the operating rods to immobilize this or these only in the unlocking direction.

Preferably, this lock-bolt comprises, in addition, means capable of preventing the blocking means from cooperating with the maneuvering rod (s) on a race which, starting from the unlocking position of the latter, is at most equal to the persistent play between the organ (s) of locking associated with this or these operating rods and the keeper (s) with which they are intended to cooperate.

So, as an example in case the ends of this or these operating rods are intended to present themselves protruding at the top and / or bottom of opening it, so as to cooperate with keepers arranged in match on the sleeping frame, this stroke will be at most equal to the clearance existing between the rebates of said door or similar.

It will also be observed that it is common to equip such bolts and bolts of a latch bolt, the control of which is carried out by means of a maneuverable follower using a handle or a constituent control button, often the manual actuation means of the operating rods. In fact, according to the invention, this lock-bolt comprises, in combination with the means of locking of the operating rod (s) in position locking as described above, means of immobilization in rotation of the maneuverable follower by the handle or the control button, in the direction of unlocking the latch bolt, these immobilization means being activated via the key element at the same time time that said blocking means of the rod (s) operation in the locked position.

Finally, we realize that through this invention a user is able to secure his door or French window by means of a locking lever whose rod (s) have not been fully locked out beforehand.

As explained above, this helps to answer, advantageously, to the problem encountered in the context of locking bolts fitted with semi-automatic actuation means of the operating rod (s). This allows, in addition, this user to lock his door or window in if its cremone bolt has a malfunction.

The present invention will be better understood on reading the following description relating to the attached drawings, in which:

• Figure 1 is a schematic representation in elevation of a bolt lock according to the present invention;
• FIG. 2 is a schematic representation of the means for immobilizing the follower in rotation ensuring the control of the latch bolt, this when these immobilizing means are brought into the active position under the impulse of the key element ensuring, by moreover, the control of a deadbolt with which the locking means of the operating rod or rods are associated in the locked position, these locking means being in the form of a pawl.

• Figures 9 to 11 show in the same situations as those illustrated in Figures 3 to 6 or again in Figures 7 to 9, a locking member defined by the free end of an operating rod.

As shown in Figures 1 and 2 of the accompanying drawings, the present invention relates, more particularly, a lock-bolt 1 for door, French window or the like, comprising, housed in a housing 2 a control mechanism 3.

In fact, this essentially comprises means 4 manual and / or automatic actuation of at least one operating rod 5, 5A extending above and / or below of said housing 2.

Preferably, the transmission of the movement communicated by through the control mechanism 3 on the rods of operation 5, 5A, is obtained by means of an easel 6 housed in the case 2. In this regard, it will be observed that in the context of two operating rods 5, 5A extending, respectively, above and below said housing 2, such rods of maneuver 5, 5A can be caused to move in a same direction, between their locked position, and their unlocking position just as their movement can be to do in opposition. In the latter case, the easel 6 cooperates, as shown in Figure 1, with a motion reverser 7, known per se, allowing, specifically, to transmit to an operating rod 5 a movement in the opposite direction from that communicated to the other 5A operating rod through the mechanism command 3.

As for the actuation means 4, they have been shown, in this figure 1, in a manual embodiment and consist of a follower 8 provided with a housing 9 for the reception of a maneuvering square corresponding to a handle or a control button not shown. Specifically, this follower 8 cooperates through an organ 10, here in the form of a fork, with the easel 6 so that under the impulse exerted by the user on said follower 8 by means of the handle or the control button, this results in the displacement of said easel 6 therefore operating rods 5, 5A, in view, either locking or unlocking.

Note, in this regard, that such operating rods 5, 5A, are, as the case may be, able to act on one or more locking members intended to cooperate with strikes arranged in correspondence on the sleeping frame, and / or their free end can be brought into the locking position, to appear protruding from the upper end or lower of the amount before opening it so that cooperate with strikes there again, correspondence at the level of the sleeper frame cross member or threshold.

Anyway, if in the illustrated embodiment in FIG. 1, these operating rods 5, 5A are present, appreciably, in the extension of the front edge 11 of the housing 2 so that they are brought to come move to the back of a faceplate usually recessed at level of the edge before the opening, these operating rods 5, 5A can still be located at any location in the thickness of the opening. In these conditions, the easel 6 acts at the ends, on pieces of appropriate configuration transmission capable of transmitting the movement communicated to this easel 6 to said rods of operation 5, 5A.

In fact, according to the invention, this bolt lock 1 receives, in in addition, a key element 12, of the barrel type, for controlling blocking means 13 of the operating rod or rods 5, 5A, in the locked position. According to a peculiarity of this invention, these blocking means 13 consist of a locking pawl 14 which, under the impulse of the key element 12, is designed capable of cooperating, in the locked position, with a rack 15 associated directly or indirectly with the operating rod (s) 5, 5A to immobilize this or the latter in the unlocking direction only.

As shown in Figure 1, the locking pawl 14 is associated with a support 16 slidingly mounted in the housing 2, transversely so perpendicular to the direction of displacement of the operating rod (s) 5, 5A or else of the bridge 6, the movement control of this support 16 carried out by means of a training finger 17 controlled by the key element 12.

According to the preferred embodiment shown in this Figure 1, the support 16 of the locking pawl 14 is defined by the body 18 of a deadbolt 19 which, in the position of locking is able to appear protruding from the edge before opening it so that it can cooperate with a keeper arranged in correspondence on the frame, while that in the unlocked position this deadbolt 19 is erased inside the housing 2.

• en communiquant par l'intermédiaire des moyens d'actionnement 4, aux tringles de manoeuvre 5, 5A, donc au chevalet 6, un déplacement en direction du verrouillage repéré par la flèche V, ces dentures 20, 21 agissent telles des cames les unes sur les autres conduisant au retrait de la denture 20 dudit cliquet 14 contre l'action de moyens de rappel élastiques 22 ;
• lors d'une tentative de déplacement de cette ou ces tringles de manoeuvre 5, 5A donc du chevalet 6, en direction du déverrouillage (flèche D) en amenant ces dentures 20, 21, de part leur profil, à se comporter telles des butées on empêche le chevalet 6 de se mouvoir dans une telle direction de déverrouillage.

In fact, in its locking position, this dead bolt 19 brings the locking pawl 14 in cooperation with the rack 15 which is, here, associated with the bridge 6. This locking pawl 14 has a toothing 20 thus coming to cooperate with the teeth 21 of this rack 15, these teeth 20, 21 being of asymmetrical shape defined so that:

• by communicating via the actuating means 4, to the operating rods 5, 5A, therefore to the easel 6, a movement in the direction of the locking indicated by the arrow V, these teeth 20, 21 act like cams on each other the others leading to the withdrawal of the toothing 20 of said pawl 14 against the action of elastic return means 22;
• during an attempt to move this or these operating rods 5, 5A therefore of the easel 6, in the direction of unlocking (arrow D) by causing these teeth 20, 21, by their profile, to behave as stops on prevents the bridge 6 from moving in such an unlocking direction.

It will be observed that the length 23 of the rack 15 can be so determined that the locking pawl 14 is able to cooperate with this rack 15 under the impulse of the key element 12, whatever the position adopted by the easel 6 and, consequently, by the operating rods 5, 5A.

Consequently, such blocking means 13 can be activated, while locking by means of these rods operation 5; 5A is only partially insured. All in particular, it will be observed that in this figurative case, the deadbolt 19 can be freely moved to its position locking so as to secure, at least partially, the door or window fitted with a lock-bolt 1.

In fact, as visible in Figure 1, the lock-bolt 1 may be provided with means 24 provided capable of preventing this cooperation between the locking pawl 14 and the rack 15 bridge 6 until at least one attempt has been made to locking of the operating rods 5, 5A, otherwise it could happen that the user unintentionally omits secure your door or window through the organs locking dependent on this or these operating rods 5, 5A.

In fact, according to the invention, these means 24 are provided capable of prevent cooperation of the locking pawl 14 with said rack 15 on a stroke 25 corresponding, at most, to the clearance existing between the place where normally cooperate with the strike (s) the locking member (s) and this or the latter when the operating rod or rods 5, 5A are in the unlocked position.

In Figures 3 to 5, 6 to 8 and 9 to 11, are shown locking devices marked 0 in different forms of realization, either, respectively, in the form of a bit, a roller or roller, or in the form of an end of operating rod. These locking members have each times have been illustrated in their unlocked position, locking and in that where this locking member 0 comes into cooperation with the strike G on the frame. In each of these cases we also identified the game or race 25.

For example, when the locking member 0 is able to to be activated by an operating rod is defined by the free end of the latter which is capable of represent salient in relation to the upper song or lower of the opening to cooperate with a keeper G arranged, in correspondence, at the level of the frame or the threshold of the door or the like, the stroke 25 will be substantially equal to the clearance persistent between the rebate of the sash and the frame or the door threshold.

Substantially, the aforementioned means 24 consist of a stop 26 secured to the easel 6 and coming to be positioned in front of the locking pawl 14 when the rod (s) operating 5, 5A are in the unlocked position preventing, thus, their immobilization via this ratchet of blocking 14, the height of this stop 26 being a function of the race 25 above.

Finally, such a lock-bolt 1 can still be provided of a spring return bolt 27 in elastic position locking, on this latch bolt 27 being able to act a control finger 28 associated with a follower 8 which, in a mode of preferential realization, is the same as that by through which the user can act on the easel 6 therefore the operating rods 5, 5A. In fact, such a follower 8 is provided, under these conditions, with several crowns which allow him to intervene, selectively and / or simultaneously on this latch bolt 27 or these operating rods 5, 5A when ordered in rotation under the impulse exerted by the user on a handle or a control button provided suitable for act on said follower 8.

As shown in Figure 1, this follower 8 can still be subjected to elastic return means 29 having for function of systematically bringing back the handle or the button in a well defined rest position.

Advantageously, this cremone bolt or cremone bolt 1, in accordance with the invention comprises means 30 for immobilizing rotation of the follower 8 at least in the direction 31 corresponding to an unlocking command, as the case may be, for said U-bolt 27 and / or the operating rod (s) 5, 5A; these means 30 being activated by the key element 12 simultaneously to the locking means 13.

Substantially, such means of immobilization in rotation 30 consist of a locking foot 32 which, in the active position, is able to cooperate with a tooth forming a stop 33 associated with the follower 8 to immobilize it rotating in the direction 31 cited above. This locking foot 32 is subjected to a movement of translation between an active position and a non-position active under the impulse of a training finger 34 capable of be controlled by the key element 12.

In this regard, this locking foot 32 is provided with a 35 defined transmission capable of transforming a movement of rotation communicated to the training right 34 by through the key element 12, in one movement linear between an active position and a non-active position of the locking foot 32.

It will be observed that, if FIG. 1 of the attached drawing illustrates an exemplary embodiment of this transmission member 35 la present invention is not limited thereto and other modes are of course conceivable.

Finally, as appears from the above description, a bolt lock according to the present invention, not only makes it possible to lock a door or window even if the operating rod (s) 5, 5A are not fully brought into their locked position, but, in also offers a level of safety which even under these conditions remains particularly high.

It should be noted that the subject of the present invention will be of particular interest in the context of locks and bolts said semi-automatic with means of elastic return of the operating rod (s) 5, 5A in locking position.
