Description
Title of the invention: Housing for multipoint lock technical field
[0001] The present invention relates to the field of building construction, both residential and commercial. In particular, the invention relates to an auxiliary housing for a lock and a lock comprising such an auxiliary housing. Previous technique
[0002] Multipoint locks generally include a central housing, of the kind which includes for example an operating lever, and at least one auxiliary housing, actuated by the central housing, to provide several fixing points at different locations.
[0003] Thus, locking the middle housing causes the locking of the auxiliary housing(s), and vice versa for unlocking.
[0004] In some cases, due to friction of a bolt of an auxiliary housing in its strike plate, the locking and unlocking of the lock may be complicated, or even fail. Description of the invention
[0005] There is a need to have an auxiliary multipoint lock housing which improves and facilitates the locking of the lock, while maintaining the security of the locking of the entire lock. Summary of the invention
[0006] The present invention meets this need by means of, according to one of its aspects, an auxiliary housing for a multipoint lock, comprising: - a box; - a movable drive between a first position and a second position relative to the chest, the drive comprising at least one locking actuator and at least one blocking actuator; - a movable main bolt between an unlocked position and at least one locked position, said main bolt comprising at least one main bolt actuation portion, - a movable blocker between a main bolt unlocking position and at least one main bolt locking position, said blocker comprising at least one blocker actuation portion, wherein said at least one locking actuator is configured to cooperate with said at least one main bolt actuation portion to position the main bolt in said unlocking position when the driver is in the first position and in said at least one locking position when the trainer is in the second position; said at least one locking actuator being configured to cooperate with said at least one blocking actuation portion to position the blocking in said at least one locking position of the main bolt to block the main bolt in said at least one locking position, said at least one locking actuator also being configured to cooperate with said at least one blocking actuation portion to position the blocking in the unlocking position of the main bolt.
[0007] By using a main bolt and a locking mechanism actuated by a drive comprising at least one locking actuator and at least one locking actuator, the locking and unlocking of the auxiliary housing is simplified. Main bolt
[0008] Said main bolt actuation portion may include a locking follower surface, said locking actuator including a locking cam, said locking cam being configured to come into contact with said locking follower surface, at least for certain positions of the driver and / or the main bolt, for the movement of the main bolt between the locking and unlocking positions.
[0009] The use of a following surface allows both good synchronization of the movements of the driver and the main bolt and without increasing the closing effort that the user has to apply.
[0010] Said locking follower surface may include a locking segment and an unlocking segment, said locking cam being configured to come into contact with the locking segment for the movement of the main bolt into said at least one locking position, said locking cam being configured to come into contact with the unlocking segment for the movement of the main bolt into the unlocking position.
[0011] The locking segment can be configured to allow a break in contact with the locking cam when the drive moves from the first position to the second position, particularly when the main bolt's movement from the unlocked position to at least one locking position is completed before the drive reaches the second position. This can occur, for example, when the main bolt rubs against the strike plate, preventing its full deployment. This allows the auxiliary housing to be correctly locked by positioning the drive in the second position, even when the main bolt rubs against the strike plate.
[0012] The auxiliary housing may include a main bolt return element configured to maintain contact between the main bolt follower surface and the locking cam, at least for certain positions of the driver and / or the main bolt.
[0013] The return mechanism ensures good synchronization of the movements of the trainer and the main bolt.
[0014] The locking cam may include a sliding surface intended to be in contact with the main bolt at least for certain positions of the main bolt.
[0015] The use of a sliding surface makes it possible to reduce the effort required to move the main bolt between the unlocking position and said at least one locking position.
[0016] The sliding surface can be a rotating element, for example a ring.
[0017] The material of the sliding surface can be chosen from the group consisting of steel, brass and Teflon, and a combination thereof.
[0018] The material of the main bolt is preferably steel so as to obtain a contact interface with the sliding surface among one of the following pairs: steel / steel, steel / brass, steel / bronze and steel / teflon.
[0019] The sliding surface may be in contact with the locking follower surface and / or a side wall of the main bolt.
[0020] The main bolt can be movable between an unlock position and at least two locking positions, wherein said at least one locking actuator is configured to cooperate with said at least one main bolt actuation portion to position the main bolt in at least one of the unlock positions when the driver is in the first position, said at least one locking actuator being configured to cooperate with said at least one blocker actuation portion to position the blocker in said at least one locking position of the main bolt to lock the main bolt in at least one of the locking positions.
[0021] In one embodiment, the main bolt has three locking positions.
[0022] Preferably, the main bolt has at least one first relief and the blocker has at least one second relief, the first relief and the second relief being configured to engage with each other when the main bolt is in at least one locking position and the driver is in the second position to maintain the position of the main bolt.
[0023] The main bolt may have at least two initial ridges. In particular, the main bolt may have one initial ridge per locking position.
[0024] The first relief may include an anti-return side, which prevents the disengagement of the first relief in the second relief when the main bolt is in said at least one locking position and the driver is in the second position.
[0025] This anti-return flange ensures good locking of the main bolt and secures the closure of the lock at least at the level of the auxiliary housing.
[0026] Having a plurality of locking positions makes it possible to ensure locking of the main bolt, and therefore of the lock, even in the event that the main bolt could not be fully deployed, for example when the strike plate is not deep enough and / or there is friction between the strike plate and the main bolt.
[0027] The main bolt may be a hook bolt. A "hook" bolt is defined as a bolt that includes a portion forming a hook configured to cooperate with a strike plate. The use of a hook bolt provides good resistance to forced entry when engaged in the strike plate and enhances the bolt's hold in the strike plate.
[0028] The main bolt may include a head and a leg, the head being configured to engage in a strike plate when the main bolt is in said at least one locking position.
[0029] The main bolt can pass between the locking position and said at least one unlocking position by rotation, in particular by rotation in a vertical plane, in particular around an axis passing through the leg of the main bolt. Blocker
[0030] Said blocker actuation portion may include a blocking follower surface, said blocking actuator including a blocking cam, said blocking cam being configured to come into contact with said blocking follower surface, at least for certain positions of the driver and / or the blocker.
[0031] The use of a following surface allows both good synchronization of the movements of the trainer and the blocker and without increasing the closing effort that the user has to apply.
[0032] Said blocking follower surface may include a blocking segment and a unlocking segment, said blocking cam being configured to come into contact with the blocking segment for the movement of the blocker into said at least one blocking position, said blocking cam being configured to come into contact with the unlocking segment for the movement of the blocker into the unlocking position.
[0033] The locking segment can be configured to temporarily break contact with the locking cam when the drive moves from the first position to the second position and the main bolt moves from the unlocked position to at least one locked position. This allows the blocker to move freely from one main bolt relief to another.
[0034] The housing may include a return element for the blocker configured to maintain contact between the blocking follower surface and the blocking cam, at least for certain positions of the driver and / or the blocker. Secondary bolt
[0035] The housing may include a secondary bolt, movable between a second unlocking position and a second locking position.
[0036] The secondary bolt may have a circular cross-section, parallelepiped, for example rectangular or square, ovoid, and a combination of these, preferably circular.
[0037] Alternatively, the secondary bolt may have a plurality of branches.
[0038] The main bolt may include a secondary bolt actuator, said secondary bolt actuator being configured to position the secondary bolt in said second unlocking position when the main bolt is in the unlocking position and in said second locking position when the main bolt is in said at least locking position.
[0039] The secondary bolt can move between the secondary locking position and the unlocking position by a translation, in particular in a vertical plane, preferably in the same vertical plane as that of the rotation of the main bolt. Chest
[0040] The trunk may include an upper unlocking part and a lower locking part, the drive being configured to move from the upper part to the lower part when moving the drive from the first position to the second position, the drive also being configured to move from the lower part to the upper part when moving the drive from the second position to the first position.
[0041] The blocker and said at least one blocking actuator can be positioned in the upper part, the main bolt and said at least one locking actuator being positioned in the lower part. Coach
[0042] The driver can be moved between the first position and the second position by an actuator of the lock, in particular an actuator connected to a median housing.
[0043] The trainer can be moved between the first position and the second position by translation.
[0044] The driver may include a plate on which at least the locking actuator and the blocking actuator are arranged. Multipoint lock
[0045] The invention also relates, according to another of its aspects, in combination with the above, to a multipoint lock, comprising at least one auxiliary housing as defined above and a median housing.
[0046] The lock provides optimal security against burglary by offering several locking points along the overall height of a door block, French window or window, without complicating use.
[0047] The lock may include a plurality of locking points formed by said at least one auxiliary housing and the middle housing, in particular between 2 and 10, for example 4 locking points on the top of the lock, 4 locking points on the bottom of the lock and 1 locking point at the middle housing.

[0058] In the following description, identical elements or elements with identical functions bear the same reference numeral. For the sake of brevity, they are not described opposite each figure; only the differences between the embodiments are described.
[0059] In the figures, the actual proportions have not always been respected, for the sake of clarity.
[0060] Figures 1 to 8 illustrate an example of an auxiliary housing 1 according to the invention.
[0061] The auxiliary housing 1 includes a box 2, substantially rectangular.
[0062] The chest 2 includes, for example, an upper part H and a lower part B, each part representing approximately 50% of the height of the chest 2.
[0063] The auxiliary housing 1 includes a drive 5, movable between a first position ([Fig. 1]) and a second position (Figures 4 and 5). In this example, the drive 5 moves between the first and second positions by a translation within the housing 2 along a vertical axis V extending from the upper part to the lower part.
[0064] The trainer 5 is presented for example in the form of a plate whose height, along the vertical axis V, is greater than 50% of the height of the box 2.
[0065] The driver 5 includes, in a lower part, a locking actuator 6 and, in an upper part, a locking actuator 7, which includes for example a cam, the functions of which will be described later.
[0066] The auxiliary housing 1 also includes a main bolt 10, in this example a hook bolt, movable between an unlocking position ([Fig.1]) and at least one locking position (Figures 4 and 5), in this example in three locking positions.
[0067] On [Fig.4], the main bolt 10 is in the maximum locking position, that is, the position where the hook 10 protrudes the most from the case 2.
[0068] On [Fig.5] a), the main bolt 10 is in the minimum locking position, that is, the position where the hook 10 protrudes the least from the case 2.
[0069] On [Fig.5] b), the main bolt 10 is in the median locking position, that is, the position where the hook 10 comes out of the case 2 in an intermediate position.
[0070] The choice of the locking position can be made automatically, for example according to any friction in the strike plate and the depth of the strike plate.
[0071] Alternatively, or in combination, the locking position can be selected by mechanical adjustment. Such a mechanical adjustment can also allow the selection of a preferred locking position.
[0072] For all locking positions of the main bolt 10, the drive 5 is in the same second position. In other words, regardless of the locking position of the main bolt 10, the movement possibilities of the drive 5 are identical and transparent to the user.
[0073] The main bolt 10 further comprises a main bolt actuation portion 11.
[0074] The auxiliary housing 1 also includes a movable blocker 15 between a main bolt unlocking position ([Fig.1]) and at least one main bolt locking position (Figures 4 and 5),
[0075] The main bolt 10 has a head 26 with a hook and a leg 27, which extends in particular towards the lower part.
[0076] The main bolt 10 can move between the unlocked position and one of the locking positions by rotation, in particular around an axis at the level of the leg 27 of the main bolt 10.
[0077] The rotation of the main bolt 10 takes place in a vertical plane.
[0078] The blocker 15 includes a main bolt actuation portion 16.
[0079] As illustrated in the enlargement of [Fig.2], the actuation portion of the blocker 16 includes a blocking follower surface 17 which includes a blocking segment 18 and an unlocking segment 19.
[0080] For example, the unlocking segment 19 is substantially straight and extends substantially along the vertical axis V when the blocker 15 is in the unlocking position.
[0081] For example, the blocking segment 18 is curved, in particular in the shape of a C.
[0082] The auxiliary housing 1 also includes a return element 20 which maintains contact between the locking follower surface 17 and the locking actuator cam 7.
[0083] The return member 20 can be of the elastic deformation type to achieve the return of the part.
[0084] The return member 20 includes in particular a torsion spring 21, one end of which is fixed to the housing 1.
[0085] The locking actuator 6 includes a sliding ring having a surface 8 in contact with a side wall of the main bolt 10. The sliding ring has a cam 9 in its center.
[0086] The actuation portion of the main bolt 11 comprises, as illustrated in [Fig.3], a locking follower surface 12 comprising a locking segment 13 and an unlocking segment 14.
[0087] The locking segment 13 has a substantially straight portion extending along the vertical axis V when the main bolt 10 is in the unlocked position.
[0088] The unlocking segment 14 has a straight portion extending along the vertical axis V when the main bolt 10 is in the unlocking position and a C-shaped curved portion at the base of the straight portion.
[0089] The auxiliary housing 1 also includes a main bolt return element 10, not shown, which maintains contact between the locking follower surface 12 and the cam 9.
[0090] The auxiliary housing 1 may also include a secondary bolt 25, for example cylindrical, movable between a second unlocked position ([Fig. 1]) and a second locked position (Figures 4 and 5). For example, the secondary bolt 25 moves by translation between the locked position and the unlocked position, in particular perpendicular to the vertical axis V.
[0091] The translation of the secondary bolt 25 is preferably done in the same vertical plane as the rotation of the main bolt 10.
[0092] The main bolt 10 includes a secondary bolt actuator 30, for example formed by a connecting rod. Said secondary bolt actuator 30 is configured to position the secondary bolt 25 in said second unlocking position when the main bolt 10 is in the unlocking position and in said second locking position when the main bolt 10 is in said at least locking position.
[0093] As illustrated in Figures 4 and 5, when the main bolt 10 is in a locked position and the blocker 15 is in the locked position, the blocker 15 blocks the main bolt 10 in the locked position.
[0094] The blocker 15 has, for this purpose, a protruding relief 35 at its base which cooperates with a hollow 36 of the main bolt 10 by engaging in it.
[0095] In this example, the main bolt 10 has three recesses 36, i.e. one recess 36 per locking position of the main bolt 10.
[0096] Each recess 36 has a first flank 37 and a second flank 38, the slope of the first flank 37 being greater than that of the second flank 38, according to the direction of movement of the head 26 of the main bolt 10. These flanks 37 and 38 allow an operation close to that of a rack which facilitates the engagement of the relief 35 in the recesses 36, but complicates its withdrawal by the sole movement of the main bolt 10, in particular when the driver 5 is in the second position.
[0097] This rack-and-pinion shape thus ensures a guarantee of security when the main bolt 10 is in one of the locking positions.
[0098] When the main bolt 10 is in the unlocked position, the relief 35 is not engaged in one of the hollows 36.
[0099] Figures 6 to 8 illustrate the movement of trainer 5 from the first position to the second position, and its consequences.
[0100] When the driver 5 begins its movement from the first position to the second position, the cam 9 of the sliding ring slides on the following surface 12 of the main bolt 10 at the unlocking segment 14.
[0101] This downward sliding, combined with the force of the return mechanism, rotates the main bolt 10 around its leg 27 and thus allows the head 26 to come out of the case 2 to engage in the strike plate.
[0102] The sliding continues until the cam 9 is in contact with the locking segment 13.
[0103] With regard to the blocker 15, at the beginning of the movement of the driver 5, between [Fig.2] and [Fig.6], the cam of the blocking actuator 7 slides on the unlocking segment 19 of the blocking follower surface 17.
[0104] This downward sliding, combined with the force of the return mechanism, rotates the blocker 15 so as to gradually bring the relief 35 towards the main bolt 10.
[0105] The cam of the locking actuator 7 then slides on the locking segment 18 of the locking follower surface 17.
[0106] At this moment, the relief 35 is in position to engage with one of the hollows 36 of the main bolt 10.
[0107] In the event that nothing opposes the complete rotation of the main bolt 10 and that it is going to position itself in the maximum locking position, the relief 35 will engage temporarily in the first hollows 36, corresponding to the minimum and median locking positions, to engage permanently in the last hollow 36.
[0108] Conversely, when the main bolt 10 cannot fully deploy, and is about to position itself in the minimum or median locking position, the relief 35 engages in one of the first two hollows 36.
[0109] Similarly, in this eventuality, the contact between the cam 9 of the sliding ring and the following surface 12 is broken. Indeed, the main bolt 10 is held in the minimum or middle locking position, and the sliding ring continues to move with the driver 5. Of course, when the driver moves from the second position to the first position, the contact between the cam 9 of the sliding ring and the following surface 12 will be re-established, starting from a certain position of the driver 5.
[0110] The transition from second position to first is done in the opposite way to what has just been described.
[0111] An example of a 50-point multipoint lock according to the invention is illustrated in [Fig.9].
[0112] The multipoint lock 50 comprises a central housing 51, including in particular a lever 52, and two auxiliary boxes 1.
[0113] Of course, the invention is not limited to the example just described.
[0114] The secondary bolt 25 could be different, for example of rectangular, triangular, ovoidal cross-section, or a combination thereof.
[0115] The main bolt 10 may have a different number of locking positions, in particular between 2 and 10.
[0116] The auxiliary housing may include a plurality of second bolts 25, for example between 2 and 5.
