Description

Device that prevents erroneous maneuvers and type lock hardware failed or fail-lock for sliding leaf.

The invention relates to a device that prevents erroneous maneuvers for lock type hardware failure or fail-lock for sliding leaf. The invention it also refers to a lock type hardware that failed or fail-lock for sliding leaf that involves such a device that avoids erroneous maneuvers.

The present invention will find its application in the field of construction hardware.

A certain number of devices that prevent erroneous maneuvers that correspond to the above mentioned description and whose function is to prevent a locking hardware, of type failed or fail-lock, of which the sheet is provided Sliding door, window or similar, can be manipulated while the sheet has not been previously closed against its frame.

It is understood in effect that, although it is possible block such hardware before closing the door or window, the blocking organs that it controls are likely to be carried in a position in which they can no longer cooperate with corresponding strikes in the frame. Therefore, in the time to try to close the door or window, these organs of blockage collide with these strikes.

This may result in deterioration of the locking hardware organs. In particular, within the framework of a fail or fail-lock, the bars can warp to a point such that the locking hardware is no longer functional and prevent any further blocking of the door or window.

As prior art, different are known devices that prevent erroneous maneuvers more or less complex.

In particular, it is known to integrate such devices that prevent erroneous maneuvers in the main box of the Locking hardware control mechanism. It is obvious how about integration makes this control mechanism more complex and, therefore So much more expensive. It also generates an increased volume in this box of failure control mechanism or Failed-lock.

From document DE-29.18.274, also knows a device that avoids wrong maneuvers to it failed to be presented in the form of a planned box capable of position itself in a recessed groove in the renewal of carpentry. In particular, this box extends behind the guard of the fail or fail-lock with the which is attached and that also covers a planned maneuver bar capable of moving longitudinally between a position of lock and unlock, under the action of a control mechanism appropriate.

This box contains a blocking finger here. displacement perpendicular to the axis of said maneuver bar or also to the guard, this locking finger being pushed in active locking position under the impulse of a spring provided in The bottom of the box.

In particular, the blocking finger must cooperate with an accessory piece applied against the back of the maneuvering bar and defining, under the latter, two stops transverse between which said blocking finger is pushed to immobilize the movement of said bar once the sheet.

As for the means of unlocking, these are defined, on the one hand, by a tongue that extends above the Locking finger, substantially in the median plane of the bar maneuver that involves, on the other hand, a light that allows the passage of this tab. The latter also crosses an opening adequate in the guard to appear outgoing regarding this last. On this protruding end of the tongue a button is applied  of control on which a placed actuator is able to act in the frame renewal. More precisely, at the time of close the sheet against the frame, the actuator, which acts as a cam, push the tab towards the inside the box corresponding to the device that avoids wrong maneuvers. This action is passed on the finger of lock that is released between the transverse stops, to allow finally the movement of the corresponding maneuver bar I was missing her.

In view of the above description, it is convenient conclude that the solution proposed in this document DE-29 18 274 requires the addition of a piece additional behind the maneuver bar to allow locking of the latter in the leaf opening position. In addition, such solution leads to substantially increase the depth of the box that requires an additional cut in the carpentry.

Also, of the document EP-A-1,004,735 is known a device that prevents erroneous maneuvers for failure or fail-lock which also means designed lock capable of locking the bar or bars in translation maneuver of this fail or fail-lock when the door or window leaf is in a any of its opening positions, and unlocking means intended to deactivate said blocking means at the time of close the sheet against its frame. The blocking means consist on a locking finger that are positioned in a box so that it extend perpendicularly behind a maneuver bar and capable to cooperate with one or more openings in the latter under the impulse of elastic recoil means. As for the means of unlocking, these are defined with a control finger that extends said blocking finger and passing through a light adapted in the bar of maneuver so that outgoing appears in the renvalso of the sheet. In this control finger it is planned to act a actuator at the time of closing the sheet against the frame, of so that this locking finger is pushed into a position released from the maneuver bar

In a particular application for a sheet of Sliding type, also known, of the document FR-2,763,981, a locking hardware that involves a hook latch attached to a sliding assembly. This hardware behaves, as a device that avoids wrong maneuvers, a finger mobile probe substantially in the transverse direction to said sliding set. This probe is permanently requested by elastic means to push it into an outgoing locking position in which this probe has an element that forms a stop and which cooperates with complementary means of the sliding assembly to prevent this, and therefore the hook latch, from being pushed in its locked position. In the solution described in particular in this state of the art, the probe is defined able to cooperate with the strike in the frame with which it is designed capable of cooperating the hardware hook latch of blocking.

While these solutions state the technique generally give full satisfaction, the device that avoid erroneous maneuvers is usually designed so that Perform its single function, that is to avoid mishandling of the locking hardware with which it is associated.

Within the framework of a first inventive activity It has been imagined that this device prevents erroneous maneuvers can perform other functions, generally associated with others means that represent additional pieces with which it is convenient routinely provide a lock type hardware failure or fail-lock for implantation in a leaf slide.

Thus, during the assembly of this failed or he died-lock in the carpentry, his positioning, before fixing, along the upright front of the sliding leaf is essential, since it depends on it its subsequent operation and correspondence with the locksmiths in the rack.

To this end, it happens very often to provide this failing or failing-organ lock prepositioning designed capable of cooperating with means of complementary prepositioning planned at the level of carpentry.

Thus, very often the front stile of the Sliding sheet includes a groove groove of the fault or Failed-lock. At the bottom of this slot you can a designed opening capable of receiving a pin from prepositioning, for example associated with a bar guide in the guard. It is clearly understood that this bar guide with the which is planned the fail or fail-lock It must be of particular design to include such a large prepositioning

Also, as usual, a sheet is mounted sliding on guide rails that involves the frame. For the therefore, the latter can be disengaged from its frame usually through an action that involves raising the sheet.

Precisely, to avoid such disengagement from the sliding leaf, for example in the framework of an attempt to effraction, it is also usual to provide this type of carpentry with a adapted device that prevents lifting. Such devices they can be directly associated with the locking hardware or present in the form of components and dependents of which the sheet must be provided, including the frame.

It is understood here that the fact of making sure a sliding sheet by means of such a device that avoids survey consists of providing it with additional components of which should manage both manufacturing and mounting.

In a complementary inventive activity, it has been imagined that such a device that avoids erroneous maneuvers, that also plays the role of means of prepositioning the locking hardware on the sliding blade, can ensure a function which prevents the lifting of the sliding blade.

To this end, the invention relates to a device that prevents erroneous maneuvers for locking hardware type fail or fail-lock for leaf slide, which includes a designed locking finger capable of move behind a maneuver bar according to one direction perpendicular to the latter and subjected to recoil means elastic in locked position of said maneuver bar, being This extended locking finger with a stylus designed capable of extending in front of said maneuvering bar so that it can push said locking finger in the unlocked position during the sliding leaf closure, characterized by the fact that the finger of lock is prolonged, behind the maneuver bar, by a prepositioning designed designed to cooperate with a opening in the sliding leaf, to ensure the positioning of the fail or fail-lock in the latter.

According to another feature of the invention, the probe has a designed centering head capable of cooperating with an opening that forms a strike in the frame against the which sliding sheet is designed capable of closing to define a device that prevents the lifting of the sliding blade with respect to said frame.

The invention also relates to a hardware of fail or lock-lock type lock for sliding blade that includes such a device that avoids maneuvering wrong.

The present invention will be better understood by the reading the description that follows and which refers to an example of realization.

The understanding of this description will be provided with reference to the attached drawing, in which:

- Figure 1 is a schematic representation of a sliding blade that includes, as blocking hardware, a fail or fail-lock provided with a device that prevents erroneous maneuvers according to the invention;

- Figure 2 is a schematic representation and in elevation of the device that avoids erroneous maneuvers according to the invention;

- figure 5 is a view similar to figure 3, which illustrates the device that prevents erroneous maneuvers mounted in this failed or died-lock.

The present invention concerns the scope of locking hardware for sliding leaf.

In particular, the invention relates to a device that prevents erroneous maneuvers 1 for locking hardware of type fail or fail-lock 2 for leaf slide 3. In particular, such sliding sheet 3 involves a front upright 4 which during slide closure is pushed against the corresponding post 5 of the frame 6. Precisely, at the height of this front stile 4 of the blade slide 3 is implanted the fault or fail-lock 2. Thus, by way of example, at level of this front upright 4 a slot can be provided of recess 7 which is illustrated in Figure 3, in which it is planned capable of positioning said failure or fail-lock 2.

The latter usually involves a mechanism of control housed in a main box 8, represented so schematic in figure 1. About this control mechanism is the user can act by means of a handle and / or a key element 9 for locking and unlocking control. TO this purpose, above and / or below said main box 8 is extends a maneuver bar 10 whose displacement control is impact on blocking organs, such as hook latch 11 or similar.

In this recessed slot 7, this or these maneuver bars 10 are usually behind a save 12.

Returning to the device that avoids maneuvering wrong 1, this one involves a locking finger 13 that extends behind a maneuver bar 10 and is designed capable of move according to a direction 14 perpendicular to this bar maneuver 10.

Precisely, this locking finger 13 is subjected to elastic recoil means 15 that push it into its lock position in which lock finger 13 is inserted into an opening 16 in said maneuvering bar 10 to secure the maintenance in the unlocked position of the latter. In sum, in this locked position, failed or fail-lock 2 cannot be manipulated to be blocked up.

On the other hand, the lock finger 13 is prolonged with a stylus 17 designed capable of extending in front of maneuver bar 10, beyond guard 12, so that this probe 17 can push said locking finger 13 into position for unlocking during the closing of the sliding leaf 3 against the frame 6.

Thus, the probe 17 can, at the time of close the sliding leaf 3, cooperate with the stud 5 of this frame 6, which has the consequence of pushing this probe 17 and therefore lock finger 13 behind the bar of maneuver 10, releasing, with respect to the opening 16 in the latter, said blocking finger 13 against the action of the means of elastic recoil 15.

In substance, the blocking finger 13 consists of a substantially cylindrical end of tight section, so that can be inserted into it, to the circular opening 16 in the bar of maneuver 10 and thus lock the latter in position unlocked

A connection bar 18, of more section reduced than locking finger 13, connects the latter to the probe 17, passing through the maneuver bar 10 and guard 12. More precisely, in said maneuvering bar 10 a oblong light 19 communicating with the opening 16 and width 20 adjusted to the section of the connection bar 18, so that allow free movement with respect to the latter of the bar of maneuver 10 from its locked position to its position of unlocking, and vice versa, when the device that avoids maneuvering wrong 1 is taken to its inactive position, that is, when the Sliding sheet 3 is closed against frame 6.

This width 20 of the light 19 in the bar maneuver 10 is however defined lower than the finger section lock 13.

While, at one end 21, the light 19 splices with the opening 16 in which it is designed capable of inserting the finger lock 13 to keep maneuver bar 10 in position unlocked, this light 19 advantageously communicates, at its end opposite 22, with another opening 23 which, in turn, is defined superior to the section of the blocking finger 13.

In fact, this opening 23 is provided in the maneuver bar 10 so that it is positioned, when it failed or fail-lock 2 is locked, in front of a opening 24 in guard 12 that serves as a passage for the bar connection 18 connecting the locking finger 13 with the probe 17, the which extends in front of the maneuvering bar 10, just as explained above.

Preferably this opening 24 in guard 12 it is, in turn, of section more important than that of the finger of lock 13, thus allowing assembly, from the front of guard 12 of the fail or fail-lock 2, of the device that prevents erroneous maneuvers 1.

More precisely, for this assembly the fail or fail-lock 2 is pushed into its locked position so that the openings 23 and 24 coincide. At this time, the lock finger 13 can be inserted through the latter until it is extend behind the maneuver bar 10. The fault or fail-lock 2 can then be unlocked, resulting in the insertion of the light 19 on the connecting bar 18 until the blocking finger 13 coincides with the opening 16 At this time, the door or window leaf may open, which causes the insertion of the locking finger 13 into this opening.
16.

According to a preferred mode of execution, the finger of lock 13 involves a head that forms a section stop 25 substantially more important capable of forming a stop that limits the insertion of the blocking finger 13 in the opening 16 of said bar of maneuver 10.

It will be noted for this purpose that openings 23, 24 respectively in maneuver bar 10 and guard 12 are adjusted to this section of head 25, to allow its passage and the mounting from the front of the device that prevents wrong maneuvers 1.

According to a particular feature of the invention, the device that prevents erroneous maneuvers 1 also constitutes means of the locking hardware in the carpentry.

In particular, the blocking finger 13 is prolonged, behind maneuver bar 10, so that it defines a prepositioning strip 25 designed capable of cooperating with an opening 26 suitably provided at the bottom of the groove recessed 7 at the level of the sliding blade 3.

In substance, the prepositioning count 25 can be defined by the head that ends the blocking finger 13 and that serves as a stop. So, this head or count of prepositioning 25 can be defined of sufficient length to precisely be able to insert into the opening 26 in the recessed slot 7, even when the device that avoids Wrong maneuvers 1 is active.

It will be noted that, apart from this function of prepositioning, this cooperation of the blocking finger 13 with the carpentry leads to better guided travel of the device that avoids erroneous maneuvers 1. Indeed, the whole defined by the probe 17, the connecting bar 18 and the finger of lock 13 is guided, a first time, through light 19 in the operating bar 10 and opening 24 in guard 12. The cooperation with opening 26 at the bottom of the groove Recessed 7 complete this guide.

According to another feature of the invention, the device that prevents erroneous maneuvers 1 is defined capable of constitute a device that prevents the lifting of the blade slide 3 when it is closed against its frame 6.

To this end, the probe 17 is also defined capable of being inserted into an opening that forms a lock 27 provided adapted to the frame 6 when this sliding sheet 3 is closed. On the other hand, this probe 17 has a head 28 defined in a frustoconical way to facilitate its insertion in this opening that forms a lock 27 in the frame 6.

Let us also specify, as regards the means of elastic recoil 15, which these are substantially defined, according to an embodiment example, by an inserted coil spring on the connecting bar 17 so that it interposes between the saves 12 and the probe 17, after the assembly of said device which Avoid wrong maneuvers.

Also according to another feature, below the probe 17 said connecting bar 18 may involve a piece 29 of section greater than the width 20 of the light 19 in the bar 10, to improve spring retention and limit the stroke of the probe 17 and, consequently, that of the blocking finger 13 in Unlocking address

The advantages derived from this invention consist of using a simple device that avoid erroneous maneuvers 1 of easy design and very easy placement of a fail or fail-lock for leaf Sliding can be made safe, not only from the point of view of its manipulation, but its prepositioning in carpentry It is facilitated.

In addition, this device that avoid erroneous maneuvers, when defining a device that avoids lifting, you can make the sliding sheet safe by avoiding a attempt of effraction by lifting and unhooking this sheet sliding with respect to its frame.
