LOCK FITTING

A fitting, including locking, comprising means for mounting on the surface a tubular profile of a sash door, window or the like.

The present invention will find application in the field of fittings, including locking, door, window or other.

Many fittings are provided for the fixing surface mountable on a joinery, such as a leaf or a door frame, window or the like.

In this connection, if this attachment occurs on the inside to a residence, it is customary to call, as fixing means, screws that are fitted within the same thickness of the joinery.

In some cases, this fitting surface mountable on the inside of a door or window may to coact with a fitting component mounted on the outer side to actuate locking members. It is, then, frequent to use screws to secure the fitting inner thereof, but also the external fitting, on the joinery.

By way of example, the internal fitting of the screw passes through the thickness of the joinery to engage a threaded sleeve nut that has, in correspondence, the external fitting, on its side for being applied on the external face of said joinery. These fastening means are, therefore, not accessible from the exterior of the dwelling.

In any case, the screwing is considered a long run operation. In order to respond to this difficulty and allow the carpenter to circumvent some of these operations of screwing, it has, for example, been devised, in the field of fittings for sliding wing, a solution for providing a snap-on fixing of a fitting on a joinery.

As seen described in the document FR's-2.761.719, such a lock fitting for sliding door, window or the like, comprises, at the rear, the two attachment members provided for placement above the housing ends.

These organs of entanglements have means adapted for engaging the edge of a slot made in the front pillar of the sliding leaf. They are thus designed to ensure perfect immobility transverse and longitudinal of the fixing plate on the surroundings of this light.

Particularly, said catching members act in opposite longitudinal directions and at least one of them is provided elastically retractable. In this connection, at its free end, opposite the return spring, the catch member is tapered to define a ramp facilitating its erasure during assembly of the fitting on the joinery. Furthermore, at the free end of this member even hooking, the first ramp joins a second ramp through which it engages behind the edge defining the opening in the joinery. Under the action of the return spring, this second ramp produces a pulling effect on the fixing plate. It is, therefore, against the woodwork.

The it should be noted, as regards the fixed attachment element, at the opposite end of the housing, it is associated with the stop function for the positioning of the lock fitting in the opening in the sliding sash.

It comprises although if such hooking members facilitate mounting of a fitting adapted to be fitted to an inner side of the joinery to the dwelling, they do not form suitable for mounting, outer side of the joinery.

Indeed, attachment members, as described in the document FR's-2.761.719, are provided to authorize the removal of the fitting by acting on the same side where the mount has intervened.

In particular, a simple movement of the fitting in the longitudinal direction results in compression of the resilient return means acting on the catch member elastically retractable. This entails, the clearance, relative to the edge of the opening in the joinery, the attachment member, the opposite end of the fitting. It is then possible to access the locking elements.

Further, a fitting, for being applied on the outer side of a joinery, is, usually, with a key member and/or other control element adapted to cooperate with catches of the fitting inner side of the joinery. Under these conditions, it is necessary to have this cooperation occurs before the attachment, itself, of the external fitting.

If, in the context of first the inventive procedure, which has been devised to a refrigeration fitting, coming into the outer side applies on a joinery, fastening means not requiring operation of screwing, in a second the inventive procedure, it is envisaged to make these fastening means active, irreversibly, from the outer side of said joinery, preventing any stress of the ferrule by act from outside a home.

Ultimately, it is envisaged the to a solution which enables the disassembly of said external fitting, by acting from within and through the tubular profile of the structure on which it is reported.

Thus, the invention relates to a fitting, including locking, comprising means for mounting on the surface a tubular profile of a sash door, window or the like, characterized in that said fixation means comprise at least one hooking means designed to movable, between an inactive position and an active position in which it is proposed to extend underneath a coupling rim that defines an opening in the joinery, said fitting comprising, in combination, a control member, such as a key member, provided for unblocking, irreversibly, locking means adapted to maintain said coupling device in its inactive position, against the action of elastic return means.

According to another feature of the invention, said blocking means are further adapted to afford the latch device in its active position and, thus, ensure the irreversibility of the unlocking operation.

The advantages of the present invention are that it is possible to report, and on the outside surface mountable on a joinery, a fitting without requiring a screwing operation time consuming and tedious. In addition it bypasses a previously engaged control elements of the mechanism and/or the house of the fitting optionally with other fitting inserted against the inner side of the joinery.

The solution, according to the invention, has, further, the advantage of providing the fitting highly resistant to violence. In particular, none unscrewing is possible and there is danger that the fitting of the game that ascertained assumes the engagement of a tool, when tampered with.

The present invention will be better understood upon reading the description which will follow relating to an exemplary embodiment illustrated in the accompanying drawings thereto.

Figure 1 is a schematic and in longitudinal section, of a fitting, according to the invention, mounted on a tubular profile of joinery.

Figure 2 is a schematic and perspective of the fitting shown in fig. 1 illustrating the grips in their inactive position.

Figure 3 is a representation similar to Figure 2 representing the grips in their active position.

As visible in the Figures of the accompanying drawing, the present invention relates to the field of fittings more particularly provided to be mounted against a wall, externally on a joinery, such as a leaf or a door frame, window or the like.

The present invention will find particular interest in the field of fittings for sliding wing.

Thus, as seen in Figure 1, the fitting 1, object of the present invention, comes into applies, the outer side 2, on a tubular profile 3, corresponding, for example, front pillar at a sliding door of a door or window.

For this purpose, this brace 1 has, at its rear face 4, for, specifically, being applied on this profile 3, 5 means provided for fixing to the latter.

According to the invention, such fixing means 5 consist of at least one hooking device 6, 7 arranged movable, between an inactive position of I, as shown in Figure 2, and an active position has, corresponding to Figures 1 and 3. therein, the hooking device 6, 7 is provided to extend underneath a coupling rim 8, 9 that defines an opening 10 formed in the joinery, i.e. the profile 3.

More particularly, this opening 10 in the joinery is for permitting the fitting 1 to cooperate with the other of the fitting elements, in particular, to locking components, or even as part of a sliding door or window, with a fitting mounted on the inner side of the sliding leaf.

Particularly, locking means arranged to hold the 11 or the gripping devices 6, 7 I as their inactive position, against the action of elastic return means 12.

Further, these blocking means 11 are designed to be unclamped, irreversibly, by a control member 13 is shown in the Figures of the accompanying drawing, as being the key element. However, the actuator 13 can borrow another embodiment, knowing that he is necessarily accessible at one of the outer faces of the fitting 14 1.

As shown in the different drawings, a hooking device 6, 7 is in the form of a slide 15, 16 movably mounted at the rear side 4 of the fitting 1. this slide 15, 16 17 has one end shaped bolt 18 extending in a plane substantially offset, so as to be protruding from the back face 4 of the fitting 1, be able to engage in the coupling rim 8, 9 as mentioned above.

Advantageously, the fitting 1 has, as fastening means 5, two gripping devices 6, 7 acting in opposition and which, therefore, extend in opposite longitudinal directions at the back face 4 of this brace 1. and is, thus, capable of being inserted in the coupling edges 8, 9 that define the opposite ends 19, 20 of the opening 10 in the joinery, these lifters 6, 7 ensure a perfect attachment of the bracket 1.

It should be noted that if the bolt 18, corresponding to the slides 15, 16, is protruding from the back face 4 of the fitting 1, it does not extend so strictly parallel to the latter, but 21 defines an acute angle, which allows it to adapt to various thicknesses of walls 22 23 profiles 3.

As to the elastic return means 12, they come in the form of a helical spring 24 taking position in a housing 25 provided accordingly, at the back face 4 of the bracket 1.

In this housing 25 comes still engage a tab 27 extending perpendicular to the back of a slider 15, 16. Thus, the coil spring 24 is interposed between one end 26 of the housing 25 and said tab 27 this way capable of repelling the slide 15, 16 in a position corresponding to the operative position of the hooking device 6, 7.

Return from 11 to the locking means, the elements are formed, at the end 28 of a slide 15, 16, 17 opposite that of the bolt 18, by a catch 29, 30 defined adapted to cooperate with a cam 31 associated with the control member 13.

Particularly, this cam 31 is in the form of a hub rotatably mounted on the axis 32 key member defining the control member 13.

Thus, this cam 31 is defined for that, in a first angular position of P1, it lies on the longitudinal path of the attachment finger 29, 30 and in a second angular position p2 recedes relative to said path.

Thus, the P1 in said first angular position, the cam 31 is able to subscribe to the rear of a boss 33 that comprises, at its end, the catch finger 29, 30 to maintain the gripping device 6, 7 in its inactive position I more particularly, registers with while coming to the back of the boss 33, the cam 31 retains, through the hooking member 29, 30, the slide 15, 16 in a retracted position, against the action of elastic return means 12.

In contrast, by imparting rotation to the key member to cause the cam 31 in the second angular position P3, this cam 31 comes, on the contrary, aside to in front of the boss 33 this hooking member 29, 30. The slider 15, 16 being, then, unrestrained by the intermediary of the latter, it can be pressed by the spring 24. Thus the elastic return of the hooking device 6, 7 in its active state has.

In this working position has, said hooking member 29, 30 of a slide 15, 16 becomes unable to cooperate with the cam 31 and the container cannot be returning this slide 15, 16 in its initial position, against the action of the spring 24. Therefore the control release is to be considered irreversible.

In fact, as dictated by their qualifier, the blocking means function to blocking and non-drive.

As shown in the Figures of the accompanying drawing, the slides 15, 16, corresponding to the hooking devices 6, 7 and acting in opposite directions, adopt a symmetrical arrangement relative to the pivot axis of the cam 31. More particularly, the attachment fingers 29, 30 of these slides 15, 16 act diametrically opposite on the cam 31.

It should be noted that the installation of the fitting 1 occurs after arming of the system. More particularly, it is causing the gripping devices 6, 7 in their inactive position I therefor, it pushes back the slides 15, 16 in the direction of the central cam 31, against the action of the springs 24. The cam 31 initially in the second angular position p2 is turned in its first angular position in which it is inscribed p1 behind the boss 33 at the end of attachment fingers 28, 29 of the slides 15, 16.

It should be noted that the presence of lateral guide flanges 34, 35 at the back face 4 of the fitting 1, flanges 34, 35 between which are inscribed the slides 15, 16, ensures that the cooperation of attachment fingers 29, 30 with the cam 31. In fact, these guide flanges 34, 35 prevent these attachment fingers 29, 30 diverge radially with respect to the cam 31.

It will be appreciated, in effect, that the stiffness of the springs 24 is chosen relatively large for a secure attachment and prevent removal of the fitting from the outside of a dwelling.

Similarly, the first angular position in which the cam p1 31 falls on the trajectory of the attachment fingers 29, 30, more particularly of the boss 33 they comprise at their end, may correspond to the resting position of the key member defining the control member 13. In this connection, they are called rest position, that in which the key 36 can be removed from the barrel. Also, after release of the locking means 11, resulting in the return of the fastening devices 6, 7 in their active state has, the cam 31, by being returned in this angular position of P1, either on the trajectory of the bosses 33, can prevent the gripping devices 6, 7 from returning to their inactive position the I, even by acting directly on the slides 15, 16, through the channel 3 of the joinery.

In sum, the blocking means 11 occur, moreover, as a means for maintaining the at least one docking devices 6, 7 in their active state has.

Thus and as for the fitting of the fitting 1 on said profile 3, disassembly is made possible that by acting on the control member 13, here on the key member.

As apparent from the above description, the present invention advantageously responds to the problem posed.
