Description

Device for fixing and guiding the ends of a failing type hardware Failed-lock.

The invention relates to a device of fixing and guiding the ends of a failing type hardware or fail-lock able to enroll in a slot provided in the renvalso of a door, window or frame similar, said device being intended to be in solidarity with the back of a guard through appropriate means and which involves means of maintenance and guidance of a bar maneuver with respect to said guard and a guide button of at least a fixing screw that passes through an opening provided for  Such an end in this guard.

A device of this type is described by example, in document FR-A-2 747 723

The present invention will find its application in the field of construction hardware and refers in particular to the locking fittings, of type failed or Failed-lock.

In this regard, such fallebas or fallebas-locks usually involve a central control mechanism, housed in a box above and / or below which maneuver bars extend whose displacement, through said control mechanism, is impact on blocking organs, such as curlers, pallets or Similar. It also happens frequently that the free ends of these maneuver bars act, as well as organs of lock, to cooperate, in locked position, with locks appropriate.

In numerous cases, those mentioned above elements of a fail or fail-lock it positioned in a recessed groove in the renewal of a door frame, window or similar and are covered by a keep closing that slot.

In particular, such guard has holes for the passage of fixing screws that allow solidarity set with the carpentry. Therefore, facing these holes, a maneuvering bar implies, as for it, lights oblong that allow the passage of these fixing screws, without therefore preventing its displacement between, in particular, a lock position and an unlock position.

For this purpose, it should be noted that if the end of a maneuver bar is intended, with a view to define a blocking organ, to appear outgoing, for example, at the top or bottom end of a frame upright door, window or similar, which welcomes said failure or fail-lock, it is necessary to ensure its guidance with respect to the corresponding end of the guard, but also perfect the fixation of the latter in the carpentry.

In particular, it is used, to ensure this function, a bar output guide that is presented, usually, in the form of a square piece that covers the frame angle at the level of which it is able to appear outgoing said end of the maneuver bar. Therefore, one of the wings of this piece of square comes in apply, externally, against the guard. In addition, for a good mechanical resistance of the set, each of the wings of this piece of squad is provided with an opening for the passage of a fixing screw that cooperates with the carpentry. Under these conditions, one of these fixing screws pass through both the guard and the bar of maneuver, the latter being necessarily provided with a oblong hole in front of this screw, to confer the required mobility

Of the document FR-A-2,747,723 is also known a fork-shaped bar exit guide with a base adapted to be housed in the bottom of the recess groove planned at the level of carpentry. This bar exit guide it is also provided with a wing that extends parallel to said base, covering, on the external side, the extreme part of the bar, while a guiding band extends between the base and the wing and includes a through opening adapted for the passage of the end of this bar. The base also has a hole for the passage of a fixing screw located beyond the wing, with the In order to be accessible.

As for the bar, this also involves a hole that allows the passage of this screw and the fixing tool during the installation of the fault in the framework. In fact, as can be seen from the description of this document FR-A-2,747,723, this guide bar output is particularly adapted for a failure provided with a particular configuration bar and devoid of Therefore, of a guard.

It will also be noted that these fallebas or Fallebas-locks of the prior art are usually provided with guiatornillo that are fixed by riveted to the back of the guard and playing the following functions:

- guide a fixing screw that passes through of said guard in the direction of the carpentry;

- guarantee connection maneuver bar guard;

- ensure the guidance of this maneuver bar regarding said guard.

It will be noted that such a screw guide is embedded in a oblong light provided on the maneuver bar before being riveted to the guard, which allows, precisely, to secure the above mentioned guiding function.

After all, as can be seen from the description above, this guide only ensures a slight Guidance of the maneuver bar with respect to the guard. In addition, you can cause malfunction of the fault or fail-lock, particularly when it comes automatically placed in a carpentry.

More precisely, the guiding function of fixing screw is secured by a guide button adjusted to the transverse width of the oblong light on the bar maneuvers and involves an opening for the passage of said screw of fixation. In addition, this guide button often receives media that authorize its riveting at the level of the guard.

To the extent that the maneuver bar presents a limited width, the width of the oblong light provided in this last for the passage of a fixing screw is, in turn, obligatorily reduced, often just greater than the diameter of said fixing screw. Therefore, under such conditions, the hole provided in the guide button and whose section is necessarily adapted, it creates, at the level of the longitudinal sides of this button, openings, in the sense that there is an absence of surfaces for guiding the fixing screw.

It is the reason why, as it comes indicated above, a risk of incorrect placement remains of this fixing screw. If that occurs at one end of maneuvering bar, the latter's guidance is assured so imperfect, which can result in a dysfunction of the fail or fail-lock.

Anyway and as it turns out from the description above, the function, on the one hand, of maintenance and guiding the end of a maneuver bar with respect to the corresponding end of a guard and, on the other hand, the function of fixing, in particular of guiding of fixing screw are secured, so far, by two different parts whose assembly should be insured individually.

After all, the present invention aims to be able to solve the aforementioned problems through a fixing and guiding device that is not only capable of ensure perfect maintenance of the end of a bar maneuver intended to define a blocking organ, but also to contribute to the connection and guidance of a maneuver bar regarding the guard that covers it.

In summary, this device pretends to be able to perform the guiatornillo functions to the extent that can also receive at least one set screw provided to rigidly and securely fix the assembly in the groove provided for this purpose in the framework. In particular, through this guiatornillo function, the invention aims to be able to provide a solution for the different constraints linked to a mounting automated locking hardware in a carpentry.

To this end, the invention relates to a fixing and guiding device for the ends of a hardware of type failed or failed-lock capable of Enroll in a slot in the renvalso of a door frame, window or similar, said device being intended to be in solidarity with the back of a guard through the media adequate and that includes means of maintenance and guidance of a maneuver bar with respect to said guard and a guide button of at least one fixing screw that passes through an opening provided for this purpose in this guard and characterized by coming defined by a profile that forms:

- a first "U" shaped section channel that involves a background that comes in apply at face level rear of the guard, extending from this bottom, on the one hand, two parallel walls between which it is able to slide the maneuver bar and, on the other hand, the guide button of at least a fixing screw, so that it can pass through a oblong light on said maneuver bar;

- and a second section channel in the form of "U" that involves two parallel walls that extend from a bottom and whose upper edge is planned capable of relying on the rear face of the guard, while the maneuver bar comes slide in the space between these side walls, on the one hand, and between the guard and the bottom of this second channel, on the other side.

Preferred forms of the invention constitute the Subject of the dependent claims.

According to an advantageous embodiment, among the two bottoms of the U-shaped section channels that define the device profile, a distance is respected corresponding at least to the thickness of the maneuvering bar, that for mounting in said latter of said guiding device of maneuver bar and fixing screws, according to the invention.

The advantages that result from this invention consist in that the fixing screw intended for pass through the guided button necessarily passes in a appropriate section opening provided at the bottom of the first channel. Therefore, this opening, of rigorously circular section, is able to ensure a perfect guidance of this screw fixation.

In addition, through the side walls parallel to each of the channels that correspond to the profile that define the device, it is able to guarantee a perfect lateral maintenance and therefore the guidance of the bar maneuver.

It should also be noted that the upper edge of the parallel walls of the second channel can receive legs of fixing and / or positioning with respect to the guard on the face rear of which they rest.

The present invention is set forth more in detail in the description that follows and which refers to a way of embodiment given by way of example and illustrated in the figures of the attached design, in which:

- Figure 1 is a schematic elevation view and in longitudinal section of said device according to the invention, applied to a failing type locking hardware or fail-lock;

- Figure 2 is a schematic view and from above the device illustrated in figure 1;

- Figure 3 is a schematic representation and in section according to III-III of figure 1.

As can be seen from figure 1 of the design attached, the present invention relates to the field of hardware lock, fail or lock-type, that, under the influence of a control mechanism housed in a central box 1, allow to communicate a displacement to bars of maneuver 2 that extend above and / or below this box, such maneuvering bars 2 impacting their movement on blocking organs, such as rolls, pallets or the like.

Very often, it failed or fail-lock is positioned in a slot embedding planned for this purpose in the renewal of a framework of door, window or similar, slot in which it is covered through a guard 3 with which the box can be supported one.

The invention relates in particular to a fixing and guiding device 4 provided capable of being inserted at the back and at one end of guard 3 by a Suitable medium 5, in particular by riveting. This device 4 It aims to be able to contribute, on the one hand, to maintenance and guided by the operating bar 2 with respect to this guard 3 and, by on the other hand, when guided by a fixing screw that passes through of an opening 6 of the latter to stay at the bottom of the slot and thus solidarity the whole with the carpentry.

Therefore, this device 4 behaves, at less, maintenance means 7 and guiding a bar maneuver 2 and a guide button 8 of at least one screw fixing, extending this guide button 8 in front of the opening 6, at the rear of the guard 3.

It will be noted that, in front of this guide button 8, the maneuvering bar 2, in turn, has an oblong light 9 sized to allow the passage of this guide button 8, authorizing at the same time an axial displacement of the bar maneuver 2 to allow the latter to pass from its position locked to its unlocked position and vice versa.

In particular, it can be seen in figures 2 and 3 which, due to the necessarily reduced dimensions in width of maneuvering bar 2, the oblong light 9 provided in the latter It also has a section reduced in width. Therefore the guide button 8 can only have a thickness 10 which is barely adjusted to section 11 of the fixing screw. In these conditions, drilling 12 present in this guide button 8 for the passage of this fixing screw generates, on the sides longitudinal 13, 14 of said button 8, interruptions 15 of the screw guide surface.

According to the invention, device 4 is presented in the form of a profile 16 defining a first section channel 17 in "U" that involves a fund 18 planned to come in apply at the level of the rear face 19 of the guard 3 and from which extend, perpendicularly, two parallel walls 20, 21 between which is able to slide the maneuver bar 2.

In the extension of this first channel 17, this profile 16 defines a second channel 22 of "U" section that it also has two parallel walls 23, 24 that correspond substantially to the extension of the walls 20, 21 and between which is positioned, here too, the operating bar 2. In fact, these parallel walls 23, 24 are supported, in this case, at the height of its upper edge 25, on the rear face 19 of guard 3, while the bottom 26, from which they extend, encloses, with guard 3, maneuver bar 2.

After all, through these walls parallel 20, 21 and 23, 24 corresponding to the first and second channel 17, 22, maneuver bar 2 is perfectly guided axially It is also well maintained with respect to guard 3 a through the bottom 26 corresponding to the second channel 22.

It should be noted that the profile term used to designate the shape of the device does not have to be interpreted in a restrictive sense, this device could already also result from a molding process.

It will be noted, in particular, that the opening 6 in the Save 3 communicates with the guide button 8 through a hole 27 of section adapted to that 11 of the fixing screw.

It is advantageously maintained between fund 18 of the first channel 17 and the bottom 26 of the second channel 22, in the longitudinal direction of the operating bar 2, a distance 34 corresponding at least to the thickness of the latter, with a view to allow the device to be mounted on such a maneuver bar 2.

Hence a perfect result. guided by the latter.

Figures 1 and 2 also show a rivet button 28 that crowns this bottom 18 of the first channel 17, on its side 29 planned to come in apply against guard 3, this riveting button 28 being provided for positioning in a drilling adapted in the latter.

In addition, the hole 27 for the screw fixing on this bottom 18 of the first channel 17 can lead to through a positioning button 30, at the level of this side 29 of said bottom 18. This positioning button 30 involves a thickness substantially equal to that of guard 3, which entails, then, an opening 6 adjusted to the section of this button 30.

Such peculiarity allows to perform on this button positioning 30 a countersink 31 to receive the head of fixing screw. In fact, such a design facilitates, widely, the inlay realization of the guard 3. In fact, the latter should usually suffer significant deformations when it is it is necessary to print a hole in it conical trunk

As can also be seen in figures 1 and 2, but also in Figure 3, the parallel side walls 23, 24 of the second channel 22 can be crowned, at the height of its upper edge 25, with at least one fixing leg and / or riveting 32 planned to stay in openings or also in notches 33 provided on the longitudinal edges of the guard 3.

Finally, to the extent that such a device, according to the invention, it allows to improve, not only, the guidance of a fixing screw, but also the guidance and maintenance of a maneuver bar with respect to its guard, it can, advantageously, constituting a bar exit guide at one end free of said guard 3.

It follows from the preceding description that the device according to the invention is particularly adapted for firmly hold the end of a maneuver bar intended for Define a blocking organ.

It should be noted that, if this device fixing and guiding according to the invention can be carried out in a single piece, in particular by a material molding process plastic or metallic, you can also contemplate doing it in two pieces, one of which defines the guide button 8 of the screw of fixation, being crowned by the positioning button 30 as well as by the riveting button 28. Under these conditions, the bottom 18 of the first channel 17 defined by profile 16 which corresponds to the second piece, it involves openings for the passage of this positioning button 30 and riveting button 28. In particular, profile 16 may result from a process of cut-inlay of a sheet metal.
