Description

INTERLOCKER LOCK

FIELD OF THE INVENTION The present invention relates to the field of cracking systems of movably mounted panels on mounting frames, more precisely interlocking systems comprising a mechanism for locking the stay.

STATE OF THE ART There are many types of traps whose function is to maintain a movable panel, such as a door or window, in a half-open position, that is to say a partial opening position. The simplest cracking systems generally consist of a latch arm having an end hingedly mounted to a mounting bracket for attachment to the mounting frame of the movable panel, the latch arm including a slot so that it can cooperate by sliding with a lug or any projecting element of a second fixing support fixed on the movable panel. The simplicity of such interlocking systems makes their use and easy assembly but they are however not robust and suffer from a lack of locking system that can condemn any position other than the desired half-open position. Interlocking devices integrated with the locking devices used to lock the movable panel, whether security locks positioned on the panel or locks directly integrated in said panel, have therefore been developed. Such devices are, however, very complex to implement and therefore requires the development of specific locks or locks adapted to operate with the mechanism of cracking. An object of the present invention is to provide a system for cracking a movably mounted panel on a mounting frame to solve at least one of the aforementioned drawbacks. In particular, an object of the present invention is to provide a tamper system whose assembly is simple, independent of any locking system of the door, and which also allows to keep the panel in a locked interlocked position. Of the invention to this end there is provided a system for cracking a movably mounted panel on a mounting frame, characterized in that it comprises: - a device entrebâilleur comprising o a support for fixing to be fixed on the mounting frame, or reciprocally on the panel; a hinge member mounted in an articulated manner on the fixing support and a member having an orifice passing through the hinge member and the fixing member being slidably mounted relative to each other; one or the other between the articulation member and the fixing member being an elongated shape defining a stay arm; a device for locking the interstellator device comprising a housing intended to be fixed on the panel, or conversely on the mounting frame, said housing comprising a light in which the fixing member of the interstage device is intended to be inserted; an anchoring mechanism slidably mounted in the housing and comprising an anchor rod intended to be inserted through the through-orifice formed in the fixing member, said anchoring rod being mounted in the housing so as to be movable between an extended position in which the anchor rod passes through the light from one side to maintain the fastener inserted into the housing lumen, and a retracted position in which the anchor rod is retracted at least partially in the case to release the fastener; and an actuator integral with the anchor rod to slide it between the deployed and retracted positions, said actuating member protruding relative to the housing; a locking mechanism comprising a locking member and an actuating member of said locking member, the locking member being arranged in the casing so as to pivot about an axis of rotation orthogonal to a longitudinal axis of the stem; anchoring between a locked position and an unlocked position, said locking member comprising a locking pin projecting in a direction parallel to the axis of rotation of said locking member so that, in the locked position, said locking pin cooperates with a portion of the anchoring mechanism to prevent translation of said anchoring mechanism. Such a system is particularly advantageous since it can be mounted on any type of movable panel, in particular on a panel already comprising a safety mechanism for holding the panel in the closed position (lock or lock).

In addition, its simple construction makes it easy to mount such a cracking system. The integrated locking mechanism also makes it possible to also secure the cracking function offered by this device. Indeed, when the locking mechanism is engaged, that is to say when the anchor rod is deployed, the panel is necessarily maintained in the interlocked position, possibly closed if the dimensioning allows, and therefore can not in any case be opened completely.

Preferred but non-limiting aspects of this cracking system are the following: the actuating member is a profiled cylinder removably mounted in the housing, and comprising an elongated profiled body and a bit mounted in rotation with respect to the longitudinal axis of the profiled body. the locking member comprises an actuating portion having the shape of a cylinder of partial revolution inside which the profiled body of the profiled cylinder is intended to be inserted, so that a rotation of the bit causes a rotation of the locking member. - The locking member further comprises an intermediate portion for radially deporting the locking pin, said intermediate portion comprising teeth for cooperating with a ball mounted in the housing at the end of a stress spring so as to constrain the rotation of said locking member. the locking mechanism further comprises a stop member for limiting the rotation of the locking member, said stop member comprising a plate-shaped portion having an opening through which the locking pin is intended to to be inserted, the walls of said opening defining the amplitude of rotation of the locking member. - The anchoring mechanism comprises a stop lug protruding in a direction parallel to the axis of rotation of the locking member, said stop lug being intended to come against the locking pin when the organ in the locked position, to form a stop preventing the translation of the anchoring mechanism. - The anchoring mechanism comprises a recess in which the locking pin is intended to be inserted when the locking member is in the locked position, to form a stop preventing the translation of the anchoring mechanism. the articulation member is a latch arm having an end mounted in an articulated manner on the fixing support, and in which the fixing member having a through orifice is mounted on the latch arm to slide between the two ends of said arm; door guard. - The fixing member comprises a spring mechanism for constraining the translation of said fastener member on the stay arm. - In the cracking system: o the actuating member comprises a removable profiled cylinder which can be inserted into a profiled passage in the housing, said profiled cylinder having a bit rotatably mounted in a profiled body, said being intended for actuate the locking member; the locking device further comprises a fixing plate intended to be fixed on the panel, or reciprocally on the mounting frame, and comprising attachment means intended to cooperate with lights provided on a wall of the housing in order to mount the housing on the fixing plate, said fixing plate being further extended by an assembly plate extending perpendicularly to the fixing plate; and o the housing, the assembly plate, and the profiled cylinder each comprise an orifice, the three orifices being formed so as to be aligned once the housing mounted on the fixing plate and the profiled cylinder inserted in the housing, the locking device further comprising a single connecting rod for securing the housing, the assembly plate, and the cylinder profiled therebetween by insertion through the three orifices.

DESCRIPTION OF THE FIGURES Other features and advantages of the invention will become apparent from the description which follows, which is purely illustrative and nonlimiting and should be read with reference to the accompanying drawings, in which: FIG. perspective of a tamper system 35 with a door-mounted locking device in a half-open position of the door; Figure 2 is a perspective view of a tampering system with a door-mounted locking device in a closed position of the door; FIG. 3 is an exploded perspective view of a locking device for a cracking system; FIG. 4 is an exploded perspective view of a door opening device for a cracking system; FIGS. 5a and 5b are perspective views of one embodiment of a bolt of the locking device of FIG. 3; FIG. 6 is a schematic representation of the mounting steps of the locking device of FIG. 3.

DETAILED DESCRIPTION OF THE INVENTION FIGS. 1 and 2 show a system for holding a movable panel in position on a mounting frame. More specifically, Figures 1 and 2 illustrate a door ajar system of a door relative to the amount of said door on which it is mounted so as to pivot. In the remainder of the description reference is made to a crank system intended to be mounted on a door which is pivotally mounted relative to a mounting frame. However, all the lessons that will emerge from this description are not limited to this particular example, so that they could be applied to any type of panel, such as doors and windows, for example, and type of articulation relative to the mounting frame on which said panel is mounted, whether a pivotally mounted panel or a panel slidably mounted relative to the mounting frame. The cracking system presented comprises a locking device 1 associated with a door-opening device 2, intended to be mounted respectively on the door 3 and the door jamb 4, or vice versa. The door-to-door device 2, generally mounted on the door pillar 4, serves to bind the door 3 of the associated mounting frame 4, while allowing said door 3 to be kept in a half-open position, that is to say say a partial opening. Such a half-open position is illustrated in FIG. 1. Thus, the door-opening device 2 generally comprises a door-stay arm which serves as a connection element between a fixing support 21 intended to fix the door-opening device 2 on the door pillar 4, and the locking device 1 which is mounted on the door 3. FIG. 2 illustrates a closed position of the door in which the cracking system is deactivated, that is to say a position in which the stay-free arm no longer connects the latch device 2 and the locking device 1, so that the opening and / or closing of the door 3 is completely free. Note that in the closed position of the door 3 as shown in Figure 2, the cracking system could still be activated, that is to say that the left arm 1 could possibly remain connected between the device entrebâilleur 2 and the locking device 1 without this preventing the door 3 being totally closed. In such a case, it is thus possible to partially open the door while leaving the cracking system active, which makes it possible to secure the door. opening of the door 3, since its opening amplitude is indeed limited thanks to the cracking system.

The latch device 2 used in the proposed cracking system firstly comprises a fixing support 21 which will allow said latch device 2 to be fixed to the mounting frame 4 of the door 3. The latch device 2 further comprises two other elements that ensure both the articulated coupling on the support 21, the attachment to the locking device 1 mounted on the door, and the desired cracking function. First of all, the intersteller device 2 comprises a hinge member 22 articulately mounted on the fastening support 21. The hinge connection between the fixing support 21 and the hinge member 22 may for example consist of in a ball joint which gives maximum freedom of movement to the articulation member 22. Alternatively, it may be provided to combine two pivot links, the first of the pivot links having an orthogonal axis to the support attachment plane 21 on the mounting frame 4, and the second of the pivot links having an axis parallel to the attachment plane, such a joint having the degrees of freedom required for proper operation of the device entrebâilleur 2. Moreover, the device entrebâilleur 2 comprises a fastener 23 which is provided to allow coupling of said interstetter 2 device to the locking device 1 mounted on the door 3. For this purpose, the fastening member 23 comprises anchoring means intended to cooperate with complementary anchoring means provided in the locking device 1 to ensure a connection between the interstice device 2 and the locking device 1. In the embodiment shown in FIGS. FIGS. 1 to 4, the anchoring means provided in the fastening member 23 of the opening device 2 consist of a through hole 230 formed through the fastening member 23, this through orifice 230 being intended to cooperate with a rod of anchoring provided in the locking device 1, as will be seen later.

In addition, the hinge member 22 and the fastener 23 are slidably mounted relative to each other, which adjusts the desired gap amplitude. Preferably, a mechanism for adjusting this gap amplitude is provided for the articulation member 22 and the fixing member 23.

The half-opening function of the latch device 2 is ensured by a latch arm, that is to say an elongate element which makes it possible to maintain a determined distance between the fixing support 21 of the latch device 2 and the locking device 1, so as to maintain a partial opening of the door 3. In the embodiment illustrated in FIGS. 1 to 4, this stay arm is formed by the articulation member 22 mounted in an articulated manner on the fixing support 21. In this case, the fixing member 23 may consist of a small, simple element slidably mounted on the hinge arm 22. It should be noted that a different arrangement could be envisaged, namely that the stop arm consists of the fixing member 23, the stay arm being hingedly mounted on a small hinge member 22 hingedly mounted on the mounting bracket 21. In particular, such an inverted arrangement with respect to the arrangement shown in the embodiment of Figs. 1 to 4 will be preferred when the mounting of the cracking system is reversed, i.e., when the locking device 1 is mounted. on the mounting frame 4 of the door while the latch device 2 is mounted on the door 3 itself. In the specific embodiment shown in Figures 1 to 4, the hinge member 22 which constitutes the interjoyer arm is a flat rod having the ends bent with respect to the longitudinal axis of the arm. The fact that the first end is bent facilitates the articulation movement of the stay arm 22 relative to the support 21, while the bent portion at the other end serves as a stop for the fastener 23 slidably mounted on the rod 22. According to this embodiment, the fastener 23 is constituted by two complementary parts 231 and 232 each provided with a groove 233 having a shape complementary to the shape of the latch arm 22 to allow translation the fixing member 23 on the stay arm 22. In addition, a spring system 234 constrains the translational movement of the fastening member 23 on the hinge member 22, which allows control of the desired gap amplitude. Any other system for controlling the relative translational movement of the fastener 23 relative to the hinge member 22 may however be envisaged, such as for example a rack system.

In the cracking system presented, the locking device 1 comprises an anchoring mechanism 10 which, as will be seen below, is intended to cooperate with the anchoring orifice 230 provided in the fastening member. 23 of the latch device 2. The locking device 1 further comprises a locking mechanism 11 for locking the latch device 2, specifically to lock the anchoring mechanism 10 when coupled to the fastener 23 2. These anchoring and locking mechanisms 11 are integrated in a housing 13 thus forming the locking device 1.

The anchoring mechanism 10 is therefore intended to allow to secure the fastener 23 of the interlocker device 2 to the locking device, so as to provide a connection between the door 3 and the corresponding door frame 4. According to the embodiment shown in FIGS. 1 to 4, in which the fastening member 23 of the interlocking device 2 comprises an anchoring orifice 230, the anchoring mechanism 10 of the locking device 1 comprises an anchor rod 101 which is intended to be inserted through the through hole 230 formed in the fastener 23. To ensure good cooperation between the anchor hole 230 and the anchor rod 101, the housing 13 of the locking device 1 comprises a light in which the fastener 23 of the interstage 2 device is intended to be inserted when one wants to fix the door arm to the door 3. The anchor rod 101 of the anchoring mechanism 10 is mounted in the housing 13 so as to be movable between an extended position in which the anchor rod 101 passes through the light 133 from one side to maintain the fastener 23 inserted into this slot 133 of the housing 13. According to this configuration, the anchor rod 101 can also be placed in a retracted position in which the anchor rod 101 is at least partially retracted into the housing 13 in order to no longer completely traverse the light 133 so as to release the fixing member 23, or to position it in the light 133 if necessary. Furthermore, the anchoring mechanism 10 comprises an actuating member 102 integral with the anchoring rod 101, and which allows to slide it between the deployed and retracted positions when the actuating member 102 is actuated. Preferably, the actuating member 102 projects relative to the housing 13, so that it can be operated manually by a user. In the embodiment shown in FIGS. 1 to 4, the anchoring mechanism 10 furthermore comprises an intermediate piece 103 which makes it possible to secure the anchoring rod 101 of the actuating member 102, this intermediate element being in the form of form of a plate arranged in the housing so as to slide. The translation inside the housing 13 of the locking device 1 may be guided by guide elements formed on the inner walls of the housing 13. Once the anchoring mechanism 10 is in the deployed position, with the fixing 23 of the interlock device 2 positioned in the slot 133 of the housing 13 so as to ensure cooperation between the anchor rod 101 and the anchor port 230, then the stay arm is firmly attached to the locking device 1 and therefore of door 3, thus allowing a crack in the door 3. However, this crack is not secure since it is possible at any time to retract the anchor rod 101 by actuating the actuating member 102 releasing Thus, the latch arm 22 of the locking device 1. Thus, to avoid any undesired retraction, it is preferable that the locking device 1 comprises a locking mechanism 11. intended to block the anchoring mechanism 10, in particular by preventing any translation of the assembly formed by the anchoring rod 101, the intermediate element 103 and the operating member 102.

The proposed locking mechanism 11 comprises a locking member 111 and an actuating member 112 of said locking member 111. The locking member 111 is arranged in the casing 13 so as to be pivotable about an axis of rotation orthogonal to the longitudinal axis of the anchor rod 101, between a locked position and an unlocked position. The locking member 111 comprises a locking pin 1111 projecting in a direction parallel to the axis of rotation of said locking member 111, this locking pin 1111 to prevent the translation of the anchoring mechanism 10 when the locking member 111 is placed in the locked position. The locking pin 1111 of the locking member 111 is intended to cooperate with an element of the anchoring mechanism to form a stop preventing the translation of said anchoring mechanism 10. For this purpose, it can be provided a pin of stop 104 in the anchoring mechanism 10, this locking pin 104 protruding in a direction parallel to the axis of rotation of the locking member 111, said locking pin 104 being intended to come against the locking pin 1111 when the locking pin 1111 is in the locked position. Another solution is to provide a recess in one of the elements forming the anchoring mechanism 10, so that the locking pin 1111 comes to be housed within this recess when the locking member 111 is in position. locked position, to form a stop preventing any translation of the anchoring mechanism 10.

The actuating member 112 allows the user to actuate the locking member 111 in order to lock the position of the anchoring mechanism 10, in particular when the user wishes to secure the coupling of the interlocking arm 22 to the locking device. 1. Preferably, the actuating member 112 is a profiled cylinder, of European cylinder type, which has the advantage of being removably mounted in the locking device 1. Such a profiled cylinder has the characteristic to present a profiled body 1121 having the advantage of having a standardized form. This profiled body 1121 encloses a rotor mounted in rotation which must be actuated by a key and on which is fixed a bit 1122 having an actuating pin projecting from the profiled body 1121 of the profiled cylinder 112, this bit being pivotable by actuation of the key inserted in the profiled cylinder 112. The fact of using a profiled cylinder 112 as an actuating member is particularly advantageous since its standardized form makes it possible to very easily replace the cylinder according to the needs of the user. In particular, it may be possible to provide a cylinder which can be actuated by the same key as that for locking the door on which is mounted the locking device 1 of the cracking system. In addition, as will be seen below, the particular structure of the locking device 1 presented here makes it possible to assemble and dismount the profiled cylinder 112 in the locking device 1 without dismantling the entire locking device 1.

When the actuating member 112 is a profiled cylinder as just described, then the locking member 111 may have a particular shape, adapted to cooperate with the bit 1122 of said profiled cylinder 112. Thus, as shown 3 and 5a and 5b, the locking member 111 comprises an actuating portion 1112 having a shape adapted to be positioned on the profiled body 1121 of the cylinder 112. In particular, the actuating portion 1112 has the form of a cylinder of partial revolution whose inner diameter is provided to correspond substantially to the diameter of the cylindrical portion of the profiled body 1121 of the profiled cylinder 112, so as to be positioned on this cylindrical portion. More specifically, the actuating portion 1112 of the locking member 111 is intended to be positioned facing the bit 1122 so that the lug of the bit 1122 can abut against the edges of the actuating portion 1112 in order to rotate the locking member 111 around the cylindrical portion of the profiled body 1121 of the profiled cylinder 112. The locking member 111 may further comprise an intermediate portion 1113 for radially deporting the locking pin 1111 said intermediate portion 1113 extending from the surface of the partial revolution cylinder constituting the actuating portion 1112 of the locking member 111.

Furthermore, this intermediate portion 1113 comprises teeth positioned radially relative to the cylinder of partial revolution constituting the actuating portion 1112, these teeth being intended to cooperate with a mechanism 114 intended to constrain the rotational movement of the actuator member. locking 111. Such a constraining mechanism 114 may for example consist of a ball intended to rest in the recesses defined by the teeth formed on the intermediate portion 1113 of the locking member 111, this ball 114 being constrained by a spring mechanism. Furthermore, the locking mechanism 11 may comprise a stop member 113 intended to limit the rotation of the locking member 111. This stop member 113 may in particular comprise a plate-shaped portion having an opening through which the locking pin 1111 is intended to be inserted, the walls of said opening defining the amplitude of rotation of the locking member 111.

To facilitate the establishment of the various elements constituting the anchoring mechanisms 10 and locking 11 of the locking device 1, the housing 13 comprises a chest 131 having a sufficient volume to receive all the constituent bodies of these mechanisms, and further comprising the passages necessary for the insertion of the profiled cylinder 112 on the one hand, and the displacement of the anchor rod 101 on the other hand. In addition, as indicated above, a light is provided in this box 131 so as to be able to insert the fastener 23 of the device entrebâilleur 2. This box 131 includes an opening large enough to be placed inside the trunk different elements forming the anchoring mechanisms 10 and locking 11 of the locking device 1. Furthermore, there is provided an element 132 for closing this opening to form a completely closed housing 13. This closure element 132 preferably has the form of a plate forming the base of the housing 13, that is to say the portion of the housing 13 intended to be pressed against the door 3, or the corresponding mounting frame 4.

When fixing holes are provided on the housing 13, it is possible to fix the locking device 1 directly on the panel, or vice versa on the corresponding mounting frame. However, this way of fixing the locking device 1 on the panel 3, or conversely on the corresponding mounting frame 4, has disadvantages, both in terms of aesthetics, since many fastening screws are visible, but also in regarding potential damage to the panel or mounting frame if disassembly of the locking device 1 was to be performed.

Thus, according to a preferred embodiment of the invention, there is provided a fixing plate 14 which is intended to be fixed on the panel, or reciprocally on the corresponding mounting frame, and comprising attachment means 141 for coupling the housing 13 to the fixing plate 14.

According to the embodiment shown in FIG. 3, the hooking means 141 of the fixing plate 14 are hooks intended to cooperate with slots 134 formed in the housing 13, more precisely in the plate 132 forming the bottom of the housing. 13. This particular arrangement thus makes it possible to couple the housing 13 to the fixing plate 14, this fixing plate 14 being intended to be fixed by fixing screws on the panel, or vice versa on the corresponding mounting frame. The fixing plate 14 not only comprises attachment means 141 for coupling the housing 13 to the fixing plate 14, but it also comprises means for securing this fixing plate with the elements forming the remainder of the locking device In particular, the attachment plate 14 includes an assembly plate 142 extending from said attachment plate 14 orthogonally. This assembly plate 142 comprises an orifice; just as the housing 13 and the profiled cylinder 112, these three connecting holes being formed so as to be aligned when the housing 13 is mounted on the fixing plate 14 and the profiled cylinder 112 is inserted into the housing 13. From in this way, a single connecting rod 15 can be used to secure the housing 13, the fixing plate 14 and the profiled cylinder 112 between them. Such an assembly rod 15 may for example have a threaded portion intended to cooperate with a reverse thread provided in the orifice formed in the profiled body 1121 of the profiled cylinder 112, so as to ensure good fixing of the assembly. In addition to the fact that this particular structure of the locking device 1 allows a very easy mounting on the panel 3, or vice versa on the corresponding mounting frame 4, this fastening method also improves the general aesthetics of the locking device 1 , since only one connecting rod 15 is used, and that it is surplus positioned laterally with respect to the face of the door and therefore very little visible. It should be noted that the fastening mechanism presented with reference to the locking device 1 for a cracking system can be used for fixing any type of locking device, not necessarily adapted to cooperate with a latch device. In particular, the locking device used may simply consist of a housing incorporating an actuating member in the form of a profiled cylinder or a rotary knob for actuating a locking member such as a bolt, bolt being intended to be inserted inside a strike. In this case, it is also possible to provide a fixing plate having an assembly plate extending perpendicularly to this fixing plate and comprising an orifice which is intended to be aligned with orifices provided both in the housing and in the housing. profiled cylinder of the locking device so as to secure these elements together.

Figure 6 illustrates the different mounting steps of the locking device 1 for a cracking system as presented in this document. Note however that this mounting method can be applied to any type of locking device having a fastening structure similar to that described. The first mounting step E1 consists in positioning the fixing plate 14 on the door, fixing it for example with fixing screws. The second step E2 consists of coupling the housing 13 to said fixing plate 14, placing the lights 134 provided in the bottom of the housing 13 on the hooks 141 of the fixing plate 14. The third step E3 then involves inserting the cylinder profile 112 inside the profiled passage provided in the casing 13, positioning it so that the lateral orifice provided in the profiled body of the profiled cylinder 112 is aligned with the orifice of the assembly plate 142 and the orifice of the case 13.

Finally, the last step E4 consists in inserting and fixing the connecting rod 15 through the three aligned orifices, so as to secure all the constituent elements of the locking device 1 between them. Besides the fact that this method of mounting and fixing on the panel, or vice versa on the corresponding mounting frame, is particularly simple, the major advantage comes from the fact that the disassembly is also very simple and avoids any damage to the mounting bracket , ie the panel, or the corresponding mounting frame. In particular, if it is necessary to change the profiled cylinder 112 or having to repair it, simply remove the assembly screw 15 and then remove said profiled cylinder 112, the other elements of the locking device 1 remaining maintained on the door 3. In the case where a greater repair is necessary, requiring opening of the housing 13 enclosing the various locking and anchoring mechanisms, it is then sufficient to remove the assembly screw 15, the profiled cylinder 112, and unhooking the housing 13 of the fixing plate 14, this avoiding removing the fastening screws inserted into the door which could damage it.

The reader will understand that many changes can be made without materially escaping the new lessons and benefits described here. Therefore, all modifications of this type are intended to be incorporated within the scope of the cracking system according to the invention.
