DESCRIPTION

Locking device and procedure for a sliding sash

The present invention relates to the field of locking devices provided for sliding doors or windows, and sliding doors equipped with said device.

A known design of bays with a sliding sash in buildings consists in forming a fixed frame with respect to the masonry around the entire circumference of a bay and closing it by means of a movable sash that slides in the plane of this frame, forming a fixed frame. The frame may include guide rails that allow the sash to slide up to a frame stud against which the sash rests when the opening is fully closed. Alternatively, the sash post can be closed against another movable or fixed post of the opening. These types of design are found especially in large windows.

An upright of the sash that forms the closing upright, generally the front upright, that is to say the one that rests against another upright, for example a frame upright, in the closed position, is provided with locking means to lock the sash against said other post when it is in the closed position. Closing devices with hooks are known in which the hooks carried by the closing post of the sash cooperate with hollow latches in a post of the frame. The hooks are fixed to a locking rod that is mounted along the closing upright and that is movable along this upright by the action of an actuation member connected to a lock box embedded in the leaf and comprising the mechanical means necessary to transform the action exerted on the operating member, for example by means of a handle, into a translational movement of the rod, which causes the rod and the hooks to pass from a passive position to an active position of lock in which the hooks lock into the corresponding receiver latches.

Such a design poses a risk in terms of the possibility of trespassing by violating the locking device. Thus, an individual may attempt to force the locking device by lifting the sash to disengage the hooks from the latch, or by sliding the rod carrying the hooks along the sash's locking post.

To improve the security of this type of closure, manufacturers try to design sash and frame uprights that have hollow profiled shapes so that the hook and the corresponding latch are not directly accessible from the outside.

In the patent application EP0882861 A1, a device for locking a leaf is proposed in which a locking hook comprises a lateral step to consolidate it during locking and unlocking maneuvers and to prevent the hook from being pushed backwards, under the action of a pressure applied perpendicular to the longitudinal axis of the operating rod, towards the notch in the upright of the leaf that contains the lock case, it being possible to exert said pressure also during an attempted robbery.

Patent application GB2276190 A1 describes a closing device comprising a male member installed on an upright and comprising an actuation lever and fixed conical projections comprising shoulders of different diameters that cooperate with a female member installed in correspondence on another upright. Said female member comprises a movable blocking plate that includes a slot that allows the passage of the actuation lever and circular holes finished off by a notch and that correspond to the rear part of the holes of said other upright in which said outgoing during lockdown. The arrangement is such that when said projections are inserted into the holes of said other upright and said holes, the locking plate is pushed downwards by gravity until a position of locking the movable plate on the shoulders of said projections, then being firmly locked together the two uprights.

In these figures, only the part of the device associated with the sash closing upright (upright not shown) that forms the male part of the device has been represented, and the part of the device associated with the frame upright (upright not shown) that forms the male part of the device. female part of the device. These figures 1 to 4 will also be described with reference to figures 5 and 6 which illustrate in exploded view respectively the male part and the female part of the device, and also with reference to figure 8 which illustrates in cross section, in the plane LT, an example of implantation of the locking device on a closing upright M of the leaf and on a frame upright D partially represented, the locking hooks of the male part hooking into the latch that forms the female part.

Figure 1 represents, according to a three-quarter and lateral perspective, a locking device that comprises a part 1, called the male part of the device, capable of being fixed by means of the counterplate 3 and the fixing screws 31, 32 on the front face. of the closing upright M, that is to say, the front upright, of a sliding sash, and a part 2, called the female part of the device, capable of being joined to the upright of the frame D in which the installed sash is located, to deal with part 1, and to be able to block the sliding leaf by taking it in the longitudinal direction L, against said upright of the frame (figure 8).

The male part 1 associated with the sash conventionally comprises a locking rod 10 capable of sliding vertically (V direction) along said sash upright M. This locking rod is associated with a set of two locking hooks 110, 111, one of which is fixed and the other mobile integral with said rod. According to the example shown, the mechanism of the locking hooks 110, 111 is included in a casing 115 of a box 11, the head of said hooks protruding through said rod 10. The functional box 11 is arranged so that the the hooks are either fixed, or according to the example the lower hook 110, while the other hook, or the upper hook 111, is configured to be mobile and to be dragged in translation by the sliding of said rod 10.

The female part 2 associated with the upright of the frame according to the example, constitutes the latch of the locking device in which the hooks of the male part 1 will engage and lock, that is, they will remain locked. This female part 2 is configured in such a way that the movable hook 111 of the mechanism of the male part 1 can actuate said latch while the locking rod 10 slides until the fixed hook 110 is locked in said latch. During unlocking, that is to say, during the transition from the active locking position to the passive position, the mobile hook 111 is dragged in translation in the opposite direction by the sliding of said locking rod towards the passive position, and releases the grip of said locking rod. mobile latch that can thus move in translation along the upright to which it is associated to return to the passive position by releasing the fixed hook.

Figure 5 illustrates, in an exploded view, a non-limiting embodiment of the male part with hooks 1 of the closing device illustrated in figures 1 to 4, associated with the upright of the leaf.

According to this embodiment, said male part 1 comprises the locking rod 10 that is capable of sliding on itself along the closing post, under the action of a control member, not shown. It also includes the hooking mechanism that is inserted into a through casing 115 of the functional box 11, that is, open on its two opposite vertical transversal faces, to contain the assembly of said hooks 110, 111, and allow the heads of the hooks to pass towards the through guide groove 1000 comprising said locking rod 10, the opening 1150 of the transverse face of the casing 115 of said casing being in correspondence with said groove 1000 of the rod. In addition, said casing 115 of box 11 allows translational movement of mobile hook 111. The set of said hooks 110, 111 comprises two support blocks 112, 113, which hold said hooks: a lower support block 113 having a generally U-shaped and between whose branches the fixed hook 110 is fastened, and an upper support block 112 having a generally U-shaped shape facing downwards and between whose branches the movable hook 111 is fastened. respective side wall 1130, 1120 of these two blocks 113, 112 is removable to allow the insertion of the respective hook. These two support blocks 112, 113 are therefore arranged one above the other, and are furthermore fixed to a transverse bottom plate 114 divided into two separable lower 1440 and upper 1441 parts, movable in an oblong groove having said casing 115 of the box on the opposite wall to 1150 that includes the sheet through which the heads of the hooks pass. The lower plate part 1440 supports and the lower block 113 supports the fixed hook 110, and the upper plate part 1441 supports the upper block 112 supports the movable hook 111, so that said two hook support blocks are also separable. The upper block 112 supporting the movable hook 111 is fixed to said locking rod 10 by means of a fixing screw 1001 that is inserted into a fixing hole 1002 made in said rod to be screwed into a receiving hole 118 in the upper part of said upper block support 112, so that said upper hook 111 supported by said upper block is made fully mobile with said locking rod 10.

Said fixed hook 110 is mounted longitudinally so that its arm rests on said lower support block 113, its curved part forming its head 1100 which is oriented downwards outside said support block, and its arm ending, opposite its head, by an end 1101 oriented vertically, at plus or minus 90 degrees with respect to the generally horizontal longitudinal part of said arm, and directed downwards.

Said movable hook 111 is longitudinally mounted so that its arm rests on said upper support block 112, its curved part forming its head 1110 which is oriented upwards outside said support block, and the opposite end 1111 of its arm oriented vertically, approximately at 90 degrees from the generally horizontal longitudinal portion of the hook arm, and directed upwards.

Furthermore, said device comprises two lateral flat rods 116, 117. One of the flat rods 116 is arranged vertically on one of the sides of said support blocks, in an external lateral groove 1131 of the removable lateral part 1130 of the lower support block 113 that holds said fixed hook 110, and in a lateral groove 1121 of the upper support block 112, said outer slots 1131, 1121 being assembled. The other flat rod 117 is arranged vertically on the other side of said support blocks, in an external lateral slot 1123 of the detachable side part 1120 of the support block. upper support 112 and in an external slot, not visible in the figure, of the lower support block 113, assembling with said upper slot 1123. These flat rods 116, 117 on one side thus maintain the support blocks of the hooks when they are inserted into the casing 115 of the box 11, and on the other hand they guide the displacement of the upper block 112 supporting the mobile hook 111 in said box, when said upper block 1 12 is dragged by the locking rod 10 in sliding.

Figure 6 illustrates, in exploded view, a non-limiting embodiment of the female part 2 of the device illustrated in figures 1 to 4, part associated with the frame upright, and capable of cooperating with the male part 1 illustrated in figure 5 which has just been described.

According to this embodiment, said female part 2 comprises a first element 20, called the front element, perforated with two entry through holes 200, 201 that allow the introduction respectively of said hooks 110, 111 of the male part 1 in the bolt. This front element 20 is fixed to a second element 21, called the lower element, which comprises spaces that receive the respective head of said hooks 110, 111. Between this front element 20 and this lower element 21 there is a third element 22, said guide element , arranged so that the block formed by the first and second elements 20, 21, called mobile block, can be mobile in vertical translation with respect to this third central transverse element 22. For this, according to the example, this guide element 22 comprises a vertical passage slot 222 for guiding said movable block by guiding the fixing bolts 26, 27, 28 that receive three fixing screws 260, 270, 280 inserted into the façade element 20 to assemble the elements 20, 21 of said block mobile. The retention housings 23, 24 (visible in the sectional figures 2 to 4) of the hooks 110, 111 are respectively formed by internal housings formed by the receiving spaces for the head of the hooks corresponding, according to the example, to the hollow spaces. 210, 211 between the bolts 26, 27, 28 of the lower element 21, in cooperation with the guide element 22, and through the entry holes 200, 201 of the front element 20 in which the hooks 110 are inserted, 111, these entry holes having an opening smaller than that of the internal housings of the hooks, in order to be able to hang there and retain the head of the hooks as shown in figures 2 to 4.

In addition, said female part 2 of the device represented in figure 6 comprises a stop 25 that limits the movement of the bolt. Said stop according to the example comprises a screw 251 inserted in an internally threaded bolt 250. The position of the stop of the latch is determined according to the position of the fixed hook of the hook mechanism of the male part of the device. This stop is adjusted during the installation of the leaf in its guide rail, having installed the sliding carriages under the leaf, in order to set the stroke height of the latch according to the configuration of the leaf in the fixed frame, in particular depending on the position height where the hooks are. In the particular case of the example of the hooking mechanism represented in figure 5, the stop 25 is placed in the lower part of the latch 2 to prevent the latch from descending when it is in an inactive position, that is to say not retained by the hooks, when the latch leaf lock is unlocked. Said stop 25 prevents the latch from descending beyond the initial position of the movable hook.

More advantageously according to the example, each hook has a chamfer 1102, 1112 in a part of the curved part that forms the head of the hook. These chamfers form adjustment means that facilitate the adjustment of the relative positions of the latch and the hooks, thus making it possible for the sliding carriages to be installed under the sash and height-adjustable in particular according to the height of the sash in the fixed frame.

In figure 2, the blocking device is in the initial blocking position. In this configuration, the respective heads 100, 1110 of the locking hooks 110, 111 of the male part 1 of the device associated with the upright of the leaf have simply been embedded in their respective receiving housings 23, 24 that includes the latch (the part female 2), after the introduction of said hooks through the entry holes 200, 201 of the front element 20 of said latch, under a thrust H applied to said leaf in the longitudinal direction L sliding towards the opposite frame upright, moving said sheet in longitudinal translation on the chassis of the frame in a manner known per se.

In Figure 3, the locking device is in the intermediate position between its passive position and its locked position, and in Figure 4 it is in the locked position in which the hooks are locked. Under the action of a control element not shown, said locking rod 10 is actuated in a translational movement in the vertical direction V and according to the example (arrow F) which jointly actuates the movable hook 111 as explained for the figure 2, and whose head 1110 abuts against the top of its housing 24 in the latch and against the wall portion 2020 of its entry hole 202 in the latch. According to the example, said locking rod 10 drives said upper support block 112 together with said movable hook 111 in motion, through the end of the arm of said movable hook. The continuation of the vertical translation movement of said locking rod continues to drive upwards the movable hook 111 (arrow F) and whose head 1110 drives said movable block of the latch, formed by the movable elements 20, 21, until blocking the movement of said locking rod. movable block 20, 21 of the female part 2 by the fixed hook 110, that is to say, to block the head of the fixed hook 110 in its housing 23 of the latch and against the internal face of the wall portion 2010 of its entry hole 201 in the latch, as shown in Figure 4.

Once the closure of the leaf has been blocked by the locking device according to the invention, if a malicious individual tries to lift the leaf to unlock it, the movable hook will try to pull the latch and will continue to lock both the fixed and movable hooks on the latch at the same time. so that it is impossible to break the lock. The two fixed and movable hooks thus locked in said latch are difficult to dislodge by a malicious maneuver, the two hooks continuing to be retained at the same time in the movable latch. For comparison and illustration, on average, the resistance force is less than 100 daN for a hook locked on a fixed latch of a conventional locking device, while for a hook of the locking device with a movable latch according to the invention, the resistance force can reach approximately 350 to 400 daN.

In figures 7A and 7B another embodiment of the male part 1' of the locking device is shown, in which the locking hooks 110', 111' can be mounted directly on the locking rod 10'. The locking rod 10' is formed by a slider installed in a front profile 100' of U-section in which said slider can slide. Such a section 100' can conventionally constitute a head of a type of system for closing a leaf. The fixed hook 110' is inserted into said front profile 100', from the outer face of said profile, by its end 1101' opposite its head 1100', through a hole 1103' made in the wall of said profile 100' , to be retained in another hole 1020' drilled in a retaining plate 102' which is located under the internal face of the wall of said profile 100'. Said front profile 100' further comprises a through guide slot 1001' through which the head 1110' of said movable hook 111' fixed to said sliding rod 10' passes. Said movable hook 111' is fixed to said sliding rod 10' by inserting its end 1111', opposite its head 1110', in a hole 1010' made in the wall of said rod. Said locking rod 10' comprises an oblong slot 106' in which the retaining plate 102' of the fixed hook 110' is located so that said rod 10' can slide on the front profile 100'. Furthermore, two fixing elements 104', 105' are inserted between the front section 100' and said sliding rod 10', by one 105', into the oblong slot 106' of said sliding rod and into a through hole 103' drilled in correspondence in the wall of the profile, and on the other 104' in a second oblong slot through 107' of said sliding rod and a hole 108' drilled in correspondence in the wall of the profile. Said locking rod 10' is thus able to slide in the U-shaped profile 100' and to make the movable hook 111' slide along the guide groove 1001' of the profile. This guide groove further determines the stroke length of the movable bolt when the locking hooks are engaged in it. The mobile latch can be the one represented in figure 6, or according to another embodiment.

In addition, in general, said blocking device according to the invention can comprise a blocking box, adapted to be mounted on the leaf, containing a force transmission mechanism suitable for transforming the movement of a maneuver of said blocking rod, into a translation of said rod along said leaf post.

In general, the sheet is made mobile by sliding on its own plane in a manner known per se, and conventionally thanks to roller carriages, or even ball carriages, installed under the sheet and rolling on a guide rail. In another possible configuration, the carriages and the guide rail can be installed in the upper part of the leaf.

The hooks of the locking mechanism are shown without limitation according to these two embodiments described in the examples with heads oriented in opposite directions and back to back, with possible embodiments where the two hook heads are oriented opposite each other.

Examples have been described for a bay window comprising a sash that slides vertically in its own plane and locks against a fixed frame, but does not limit the invention. In fact, the opening could be blocked against another stud, such as another stud of the bay window, such as a stud of another sash that would include the bay window, or a stud of a fixed panel that would include the bay window.
