Description

Sliding Blades Locking Device of a door or window.

The present invention relates to a device of blocking the sliding leaves of a door or window, which includes a fixed frame frame surrounding a swing consisting of at least two vertically mounted sheets in this frame, parallel to each other and arranged in front of each other to move in parallel

The document FR-A-2 738 590 describes a Locking device for a sliding glass.

The invention applies particularly in the case of that the chassis of each leaf of the leaflet is constituted by means of maintenance profiles of a central panel, usually of glass, generally rectangular, this sheet being suitable to be mounted with sliding capacity on the fixed frame that  it comprises horizontal lower and upper sides, being preferably equipped with the bottom side with at least one rail on which one or more cars supported by the sheet for opening or closing the door or window, performing the layout of the chassis of each sheet in a special way, so that this chassis includes only a horizontal lower crossbar under which the carriages are mounted and a vertical upright that forms two adjacent sides of the crossbar chassis against which the two corresponding sides of the central panel, the other two sides of it being devoid of maintenance profiles.

A similar conception of the structure of chassis of each sliding blade is the object of the request for FR-A-2 801 337 patent in the name of the requesting company.

In particular, in such an embodiment, when the leaflet includes two close sheets of equals dimensions that move by sliding in parallel planes on two equally parallel rails carried by the frame, it is foreseen that the two vertical uprights of the two sheets are adjacent and are arranged one behind the other in the position of closing the door or window, placing these amounts therefore practically in the middle of the frame frame width that corresponds to twice the width of each sheet.

This structure of the sliding blades of the Swing has the essential advantage of reducing shape completely significant the necessary amount of profiles of framed chassis that supports a glass panel, in effect divided by two since each sheet only includes a crossbar horizontal and a vertical upright, which ensures growth notable of what should be called "clarity of glazing ", and the elements of the chassis more easily, with a manufacturing and assembly cost noticeably less elevated.

Indeed, in this case, the profiles that constitute the chassis of the panels no longer surround the four sides of these panels, but form only one L according to two sides consecutive of each of them, the others being deprived Two sides of such profiles.

On the other hand, it is known that it is usual to provide locking means to allow, in the closed position of the door or window, that is, when the sliding leaves are arranged in such a way that they completely seal the space internal delimited by the frame, the immobilization of these sheets, means of the type particularly of a lock carried by a vertical upright of the swing chassis, which includes usual, a suitable transverse latch control mechanism to penetrate a reception strike provided in the frame fixed frame. If necessary, this mechanism may be associated with appropriate transmission organs to ensure the vertical displacement of a rod or the like whose ends, that therefore protrude out of the swing chassis, are coupled in housings provided on the high and low crossbars of the frame.

In a classic sliding swing, this lock it is generally housed in the vertical upright of the chassis of the swing which, in the closed position, is in contact with one side side of the frame of the frame, on which the strike that houses the latch of this lock.

When the swing is formed of several sheets sliders, other means which, regardless of the lock that locks or releases one of the called service hinges, block the other swing, called semi-fixed, facing frame.

Now, with the solution perfected according to the aforementioned patent application is no longer possible the arrangement of the lock on the side upright of the chassis of the leaf that comes into contact with one side of the frame of the frame, because precisely, this side post no longer exists.

Therefore, it is necessary to arrange the lock on the vertical amount of the chassis that subsists and that, in closing position of this swing, is substantially in the middle of the frame (in the case of a door or window with two leaves) or it is located in another environment of this same frame (in the case in that the number of sliding sheets is greater than two), being This lock is arranged to guarantee the mutual blocking of the two sheets one relative to another perpendicular to their uprights adjacent verticals, in mutual coating.

The present invention therefore relates to a locking device carried by at least one of the two sheets sliders in the closed position of the door or window, and suitable to block them from one another perpendicular to their uprights vertical arranged in front, being able to perform only the blocking of the two sheets in this situation, leaving these free Blades slide facing each other in any position.

In addition, the device according to the invention can be planned so that it can be operated both in the direction Locking and unlocking of the two sheets, being controlled both through one of the vertical uprights, thus including each of them separate means of control of this device.

For this, the device considered, for the locking or unlocking the two leaves of a swing of a door or window, mounted with sliding capacity in a fixed frame, each sheet comprising a chassis constituted only for a vertical side upright and a lower crossbar horizontal, this device comprising at least one mechanism of ported lock in mounting position by at least one of the vertical uprights of the sheets, it is characterized in that it includes a joint assembly controlled by the lock mechanism and a folding stop (26a, 26b) for locking the joint assembly (10), the joint assembly (10) being composed of two parts of which one can move vertically in a longitudinal groove open one of the uprights and has an external projection suitable for coupling in a reception housing provided in the second part of this set with the purpose of solidarity mutually, this second part being equally suitable for slide vertically in a homologous slot of the upright of the another sheet, controlling the displacement of at least one of the two parts of the joint assembly the movement of an appropriate latch to cooperate with a fixed strike, provided in the amount of the sheet that carries the other part, not being authorized the mechanism of lock to operate the joint assembly with sliding simultaneous and in the same direction of the two parts in their slots to ensure the penetration of the latch in the strike except when the external projection is attached to the reception housing, in addition to after the removal of the stop Folding lock of the joint assembly, being carried this butt for at least one of the uprights and being adapted to release this set under the effect of a solidarity control finger of the other upright and pushing this stop only when these two uprights are facing each other.

Thanks to these provisions, the two sheets of the Swing are free to slide each other over the entire width of the frame to occupy any relative position one with with respect to the other, the two parts of the joint assembly, covers respectively for each of the vertical uprights of these two sheets, being deolidarized from each other, immobilizing then the part of this set that cooperates with the mechanism of lock in its slot by the locking stop, making it impossible the drive of this mechanism.

Instead, when the two vertical uprights are faced, particularly in the case of a swing with two sliding blades when these uprights are arranged one facing another in the middle part of the frame, thus closing the door or window through these sheets, the external projection of one of the parts of the joint assembly fits into the housing of reception of the other party, making them mutually supportive in this position.

Simultaneously, the control finger carried by one of the two uprights pushes the retractable locking stop, releasing the joint assembly with its two parts joined to each other so that the lock mechanism can operate this set and particularly make it move in the sense that it leads the mobile latch, integral with one of the parts in the strike fixed provided in the amount, which supports the other part, blocking So two uprights with each other.

A simple reverse maneuver of the lock mechanism naturally causes the removal of the latch of your strike, releasing the two leaves, the displacement of one of them in front of the frame, which separates the two vertical uprights with each other that until now were faced, ending the action on the top retractable by the control finger, the return of this stop in starting position by blocking the corresponding part of the joint assembly, which can no longer scroll through the mechanism.

In a preferred embodiment of the device according to the invention, the vertical uprights of the two blades include one and the other a lock mechanism, the two being appropriate mechanisms to independently operate the part of the joint assembly carried by the corresponding amount.

Advantageously, one of the mechanisms, arranged on the outside of the door or window is operated by a key control, suitable for removal from the lock after a maneuver of the same, the other mechanism being maneuvered, disposed of inner side, by a push button or similar, devoid of key, allowing both of these mechanisms to perform the mutual blocking of the two sheets.

According to a particular feature, the outgoing external of one of the parts of the joint assembly is constituted by a skate or analog, which extends transversely in front of the vertical amount carrying this part, the reception housing of this projection provided in the other part forming a profile substantially U, open laterally so as not to prevent displacement of the projection with respect to this housing, during the displacement of one leaf in front of the other.

Preferably, each part of the joint assembly It consists of a narrow plate, equipped with a heel of guided coupled in the longitudinal groove of the upright where scroll vertically.

Advantageously and according to another characteristic, the device includes means of mutual alignment, consisting of two hooks carried respectively by one of the uprights, the hooks being inverted and fitting to fit one in another when the two uprights are facing each other, to improve  the vertical maintenance of these uprights during the maneuver of the joint assembly by the lock mechanism.

Preferably also, each part of the set of union includes a ratchet of spring of blockade of this part in front of the corresponding amount, at the end of the race displacement of this part in its longitudinal groove.

In a first embodiment, the stop retractable is formed by an articulated block on the upright vertical around a transverse axis, perpendicular to this upright, this taco presenting a spike in outer projection that cooperates with the control finger carried by the other amount of so that the contact of the finger with the cue, when the two uprights approach, causes the block pivot and the release of the part of the joint assembly immobilized by this stop, top, maximum as a noun, top as an adverb.

Preferably and in this embodiment, the outgoing pin slides in a circle arc groove arranged on a plate keeping the block applied against the vertical amount

In a variant embodiment, the stop Folding includes a block suitable for supporting a movement transversal in parallel to the plane of the amount under the effect of control finger acting on a protruding pin carried by the block and its movement in a horizontal guide groove.

In another embodiment of the device considered, one of the parts of the joint assembly is extended by an angled rod, which contacts a bolt pivot articulated at the time it supports this part, adapting this bolt like a latch to engage or remove of an accommodation that forms a locksmith provided in the other upright.

Other features of a device locking of a swing formed of sliding panels, established according to the invention, they will appear through the following description of exemplary embodiments, given as indicative and not limiting, with reference to the accompanying drawings in which:

- Figure 11 illustrates a variant of realization of the folding top.

- Figure 12 is a partial sectional view, analogous to that in figure 6, but illustrating a variant of realization.

In figures 1 and 2, the chassis shown indicated as a whole with reference 1, includes a frame 2 fixed, generally rectangular, consisting of an assembly of metal profiles according to the four sides of the frame, and of sliding blades, respectively 3 and 4, suitable for lodging in parallel and one in front of the other in a groove 5 of the frame being slightly displaced to slide each other against each other, being able to cover both sheets completely or, conversely, be arranged to guarantee the closing of the frame, each sheet preferably presenting a dimension in width equal to half that of the frame.

Therefore, this provision does not have in itself no imperative character, the invention can also be applied described below to a door or window that includes a number of sliding blades greater than two, not being width dimensions of these necessarily identical sheets, but that, when they are arranged in a displaced way, other, completely seal the surface of the frame.

In the following, the examples described are limited for simplicity to a door or window in the that the frame is intended to include two sliding blades identical.

According to the invention, each sheet 3 and 4 is made of compliance with the provisions described and claimed in the patent application FR-A-2 801 337 on behalf of the applicant, already cited, including each sheet a wall 6, preferably glass, particularly formed of two parallel crystals as seen in figure 3, being housed this wall in a support formed of two elements metallic, respectively a vertical upright 7 and a crossbar 8 horizontal bottom to form an L arranged on two sides consecutive leaf surrounding the corresponding edges of the wall 6, however the other two edges of amount and crossbar similar to the previous ones.

As represented on a larger scale in the Figure 3, the two sliding sheets 3 and 4, in the closed position of the frame, they have their vertical uprights, differentiated to from now on with references 7a and 7b, located so facing each other, the opposite edges of the walls being coupled 6 glass, devoid of uprights, on the corresponding sides of the frame 2.

With this arrangement, it is conceived that the assembly of a lock, indicated as a whole with reference 9 in the Figure 3, suitable for immobilizing the two sliding blades in this position must necessarily be done at the level of these uprights 7a and 7b, blocking each other mutually.

As schematically illustrated in this Figure 3, the lock 9 mainly includes a set of union indicated with reference 10 and which in fact includes two parts, respectively 10a and 10b, whose details of embodiment are explain later.

In the example shown, each of the uprights 7a and 7b of the two sheets 3 and 4, includes a mechanism different lock, carried by both of these uprights, these mechanisms being indicated necessarily by the references 11 and 12, the first including a control key and the second a push button, not really having so much the structure as the nature of these mechanisms impact on the invention by allowing, jointly or separately, to act over joint assembly 10 and more particularly over parts 10a and 10b thereof in the precise manner mentioned to continuation.

In a variant, the device could perfectly include only a lock mechanism, sufficient in itself to drive the joint assembly 10, this mechanism being normally arranged so that it can be  controlled from outside the door or window to block the same.

With more particular reference to figures 4 and 5, it is noted that each part 10a, 10b of the joint assembly 10 includes a support 13a, 13b, fixed to the post 7a or 7b respectively and where it can move longitudinally, against the corresponding amount, a plate 14a or 14b that it comprises a mounted side heel with the capacity to sliding in a groove 15a or 15b of the support.

One of the parts 10a includes on the other hand, in the face of the plate 14a in front of the stud 7b, a gap 16 with substantially U-shaped profile, open laterally to form a housing in which an external projection 17 can be arranged provided on the plate 14b of the other part 10b of the assembly 10 of Union.

Figures 4 and 5 show respectively the relative positions of the projection 17 with respect to the recess 16 of over and over the two parts of set 10, as the uprights 7a and 7b move laterally relative to each other (figure 4) or exactly one in front of the other, when the door or window is sealed as shown above (figure 5), the projection 17 being therefore arranged in the hole 16 allowing the two parts 10a to be in solidarity and 10b, particularly when moving vertically sliding in its grooves 15a and 15b.

Figure 6 illustrates in cross section the relative position of the gap 16 and the projection 17, including each one of the lock mechanisms 11 an appropriate mechanism of kite or other type that is not necessary to describe here, which allows to control this simultaneous displacement of the two parts of the joint assembly, guaranteed as the case may be by one or the other of these mechanisms, or even by only one of them when the device only includes one.

In this figure 6, the arrows f schematize the direction and breadth of movement of plates 14a and 14b in the slots 15a and 15b of their supports 13a and 13b.

In addition and in this same figure, it is observed that the device includes, on the one hand, a strike 18 carried on the example described by the amount 7a and under these conditions in fixed position with respect to it, on the other hand, a latch 19, which this time is projected overhang at the end of one of the two parts of the joint assembly 10, in this case on the plate 14b of part 10b.

It is easily understood in this case that, according to the vertical position adopted by the joint assembly 10, when the two parts 10a and 10b thereof are united together by the projection 16 of that coupled in the recess 17 of the other, the latch 19 engages, or conversely decouples, from strike 18 and block or not mutually the two uprights 7a and 7b and a then the two leaves of the door or window.

Advantageously, the uprights 7a and 7b include one and the other of the inverted hooks, respectively 20 and 21, which allow, when these amounts are facing, cooperate one with another to improve the vertical maintenance of these uprights and perfect its parallelism inside the frame.

The uprights 7a and 7b are provided spring ratchets 22 and 23 to allow immobilization of two plates 14a and 14b of parts 10a and 10b of the joint assembly in the positions that correspond respectively to the coupling, or on the contrary, to the decoupling of latch 19 in the strike 18, cooperating these ratchets respectively with notches 24 and 25 provided on the corresponding surfaces of the plates 14a and 14b

However, according to the invention the maneuver of the two parts 10a and 10b of the joint assembly 10, should only be authorized by one or the other of the lock mechanisms 11 when the two vertical uprights 7a and 7b are closely facing each other, necessarily decoupling the latch 19 of your strike 18 in any other position with respect to two sheets.

For this, the device includes, cooperating with each of the plates 14a and 14b of the joint assembly 10, two folding stops, respectively indicated with references 26a and 26b in Figure 6, these stops being arranged to be able to freeze the plates when the two uprights 7a and 7b are not in front of each other, or withdraw releasing these plates and authorizing its movement in its slots for the control of latch as explained above.

Figures 7 to 9 illustrate a first mode of realization of one of the folding stops, in this case the stop 26a associated with the plate 14a of one of the parts of the assembly 10 of union, specifying that the other stop 26b, which may be provided simultaneously to cooperate with plate 14b, it presents the same structure.

In these figures, the Sliding part 14a in the groove 15a in the associated support 13a with the amount 7a.

The retractable top 26a includes a block 27 which in The illustrated example is pivotally mounted around an axis 28 fixed, this block 27 being extended beyond axis 28 by a pin 29 projection suitable for moving in a groove 30 in circle arc provided on a plate 31 fixed against the support 13a.

Thanks to these provisions, it is understood that when the block swings around its pivot axis 28, releases plate 14a which, under the effect of one of the mechanisms of lock, you can then experience a shift towards the lower part of an amplitude measured by arrow t (figure 6), bringing latch 19 to its strike 18. Conversely, as soon as the stop 26a has its stud 27 in an upright position, it immobilizes the plate 14a and prevents the coupling of the latch and the blocking of The two sheets.

The control of the removal of the block 27 is performed by means of a control finger 32, carried by the other upright 7b, as schematically illustrated in Figure 10, coming into contact with this finger of spike 29 when the two uprights 7a and 7b are facing, describing in this spike the slot 30 and thereby swinging the block.

However, when these two uprights are not one in front of the other, the block remains in position and blocks the union set.

Figure 11 illustrates a variant embodiment in which, in this case, the pin 33 provided in projection in the end of the retractable butt plug is susceptible to experience, no longer a pivoting movement around a axis as in the previous variant, but a transverse displacement in a groove 34 of straight guidance, moving the block this time Like a drawer

Figure 12 schematically represents another embodiment for the two-leaf locking means, in replacement of the latch and the lock of the variant previously described.

In this case, plate 14b of part 10b of the joint assembly for example, includes in extension a rod 35 layered suitable for cooperating with an articulated latch 36 around an axis 37 carried by the stud 7b, retracting this latch in a housing 38 of this amount when inactive, or being arranged in a lock 39 of the other amount 7a when the maneuver of the lock mechanisms 11 or 12 allow rod 35 to withdraw and latch 36 to adopt the position illustrated in this figure.

Thus, a two locking device is realized very simple conception sheets and that adapts particularly well to the structure of a sliding blade of the type exposed in the patent application FR-A-2 738 590 of the applicant. However, of course the invention is not limited to this particular case, on the contrary, covers all variants as claimed.
