Description

The invention relates to a device for a door, window or similar handle comprising a gripping member, in the form of a crutch, a button or the like, mounted in rotation on a fixing base for the control in rotation of a transmission member, in particular an operating square, said fixing base comprising means for receiving fixing members such as screws or rivets.

The present invention relates to the field of building hardware and relates, more particularly, to door handle devices, windows or any other building joinery.

Numerous door, window or similar handle devices are already known that meet the above description. Thus, in the usual way, such a handle device comprises a gripping member most frequently taking the form of a crutch or that of a button, comprising a barrel through which this crutch or this button is mounted in rotation on a fixing base intended to be attached to a joinery, in line with the control mechanism of a locking fitting intended to be controlled by this handle device.

For this purpose, the crutch or the button most often acts on an operating square to transmit a rotation command to this mechanism of the locking fitting. Usually, this maneuvering square cooperates with a follower that this mechanism comprises.

Moreover, if this mechanism is generally installed in a joinery rebate, which has a through opening to the right of the passage of the maneuvering square, the handle device acting on the latter is usually applied on the internal side, depending on the external case. , on the carpentry. For this reason, the fixing base has openings for the passage of fixing members, more particularly fixing screws.

Different concealment means are currently used to hide these fasteners, whether for aesthetic or safety reasons by avoiding, for example, the unscrewing of these fasteners.

As concealment means, it is already known to use plugs which close recesses provided in the fixing base for receiving the heads of the fixing screws. However, it is very easy to lose such plugs during the intervention of an operator on the handle device, not to mention that it is necessary to show dexterity and application during the assembly and installation of these. caps. In addition, the integration of such caps automatically imposes aesthetic choices, which are by nature questionable, since such caps must remain visible and easily accessible to the end user.

Another known solution consists of mounting in rotation on the fixing base, a cover plate. Thus, when the latter is pivoted transversely with respect to the fixing base, it makes the heads of the fixing screws accessible for their tightening or loosening, as the case may be. On the contrary, when returned to an alignment position on this fixing base, this cover plate completely conceals these fixing screws.

Moreover, in this concealed position, this cover plate is pushed elastically into a locking position preventing any unintentional rotation. Indeed, it is only under the action of a traction exerted on this cover plate, against the action of the elastic return means, that it is able to pass such a locking position and therefore to pivot in an arrangement facilitating access to the fixing screws.

First, the equipment of a handle device with such a cover plate is particularly restrictive. This equipment must intervene at the time of manufacture of the handle device, remembering that the gripping member is permanently mounted in rotation on the fixing base. Moreover, this irreversible pre-assembly of the rotating gripping member on the fixing base is the source of additional difficulties for fitting a door or window with such a handle device.

In fact, to allow access to the fixing screws, it is often necessary to pivot the gripping member, for example by bringing it from a locking position into an unlocked position. This manipulation is accompanied by a command on the locking fitting to which the handle device is associated. However, it may prove necessary to avoid such a control of the locking fitting causing, necessarily, the locking or unlocking of the door or window while the latter is in the assembly phase at the level of a construction.

In addition, such a cover plate as a means of concealing the fasteners, induces restrictive limits to the aesthetic character that a fastening base can take. Finally, such a cover plate may require, for its pivoting, a constraining size for the frame to be fitted, in particular in terms of width and shape of the profile.

A major drawback resulting from these solutions corresponding to the prior state of the art consists in that such handle devices immediately attached to a door or window fitted to a building under construction or renovation are exposed to the risk of soiling and degradation, due to the intervention of other trades, such as plasterers, painters or others. A second major drawback is that of imposing, well before the delivery of the joinery, the choice of shape and colors of the handles.

Also, to prevent such a handle device, the aesthetic character of which is particularly important, from being altered even before the end of the construction, the carpenter is tempted to suspend the equipment of the doors or windows of the handle device during this construction phase to proceed with this equipment only at the end of the work. However, this is hardly conceivable insofar as it is often necessary to manipulate these openings which constitute these doors or windows to facilitate or quite simply allow the intervention of other trades.

It is therefore within the framework of a first inventive step that it was imagined that the gripping member could be attached in rotation on the base. fixing in a retractable manner which makes it possible to pre-equip said doors or windows with fixing bases for such handle devices when installing joinery on a building under construction, without being subsequently exposed to damage to the gripping organ. Especially during the construction site, it is possible to equip a handle device with a work site gripper, thanks to the removable nature.

In this same inventive approach, it has also been imagined that the means for concealing the fixing members of this fixing base takes the form of a cover box that can be nested on this fixing base.

Thus, the two elements which contribute to the aesthetic character of the handle device, namely the definitive gripping member and this covering box, are likely to be placed on a joinery at the end of the work, that is to say when the risks of degradation are less and that the aesthetic choices of the end user are made. Moreover, this inventive approach also induces the possibility of being able to reconsider these choices during the life of the product, by a simple and rapid replacement of the gripping member and of the cover box, without requiring complete disassembly. of the handle.

In a second inventive step, it has also been imagined that this means of concealing the fixing members of the fixing base, more particularly the cover box in the preferred embodiment of the invention, contributes to securing the assembly. pivoting of the gripping member on this fixing base.

To this end, the invention relates to a handle device, in particular a door or window, comprising a gripping member in the form of a crutch, a button or the like, mounted to pivot on a fixing base for the rotation control. of a transmission member, in particular of an operating square, said base comprising means for receiving fixing members, such as screws or the like, characterized in that the gripping member is rotatably mounted on the fixing base by means of interlocking means in its axial direction of pivoting, with which are associated resiliently return locking means in the retaining position to axially immobilize this gripping member on this fixing base.

According to another feature of the invention, said handle device also comprises means for blocking said locking means with elastic return in the locked position.

More particularly, these locking means are defined by the means for concealing the fastening member passage openings that the fastening base comprises.

The advantages resulting from the present invention consist in that the gripping member of the handle device can be attached to the fixing base by simple interlocking, its retention being ensured by elastic return locking means.

In addition, blocking these resiliently return locking means in the locked position makes it possible to prevent involuntary disengagement of this gripping member.

According to the invention also, the concealment means ensuring this locking function is in the form of a cover box for the fixing base.

Advantageously, this covering box can be fitted to this fixing base at the same time as the gripping member, fulfilling a locking function as indicated above. The perceptible exterior aesthetics, after assembly, of this cover box, can be completely independent of this function.

Other characteristics particular to the invention and the advantages which result therefrom will become apparent during the description which follows relating to an exemplary embodiment given by way of indication and without limitation.

As illustrated in the figures of the accompanying drawings, the present invention relates to a handle device 1 intended, more particularly, for joinery such as doors, windows or the like.

Such a handle device 1 comprises a gripping member 2 which can take various embodiments, in particular those of a crutch 3 as illustrated in the figures 1 and 2 , a button or the like.

This gripping member 2 is rotatably mounted on a fixing base 4 intended to be applied on a joinery, for example on the opening of a door or window.

Very generally, the pivot axis 5 of the gripping member 2 on the fixing base 4 is perpendicular to the plane 6 of application of the latter on such joinery.

The purpose of the gripping member 2 is to ensure the rotation of a transmission member 7 intended to act on the mechanism of a locking fitting such as a lock, cremone, cremone-lock or other. Such a transmission member 7 often takes the form of an operating square 8 as illustrated, in particular, in the figure 2 .

Note that the present invention is in no way limited to a direct interaction of the gripping member 2 on such an operating square 8.

In particular, as visible in the figures 3 and 5 , the gripping member 2 can act, as a transmission member 7, on a gear reduction transmission mechanism 9, which interacts with said maneuvering square 8.

One can also imagine other solutions, the invention not being limited to such an interaction between the gripping member 2 and this transmission member 7.

In a particular way to the invention, the gripping member 2 is mounted in rotation on the fixing base 4 by means of interlocking means 10 in the axial direction 5 of pivoting of the gripping member 2.

Said interlocking means 10 are defined by an assembly formed by a coaxial interlocking end piece 11 and a mating sleeve 12, one fitted to the fixing base 4, the other the gripping member 2.

In the embodiment illustrated in the drawings, the gripping member 2 comprises the interlocking sleeve 12 which fits onto the interlocking end piece 11 fitted to the fixing base 4. However, it is completely imaginable an inversion of this construction.

In such a context, the fitting end piece 11 or the fitting sleeve 12 that the fixing base 4 comprises can equip the latter in a fixed manner in rotation or, on the contrary, in a pivoting manner and define, in this case , at least in part, the transmission member 7.

In short, the gripping member 2 equipped, as the case may be, with a fitting sleeve 12 as illustrated in the drawings or with a fitting end piece can pivot around the fitting end piece 11 or the sleeve. interlocking fixedly mounted on the fixing base 4 or pivoting jointly with this interlocking end piece 11 or this interlocking sleeve rotatably mounted on this fixing base 4.

In the embodiment shown, the gripping member 2 comprises a fitting sleeve 12 which fits onto a fitting end piece 11 to drive the latter in rotation, moreover mounted in rotation on the fixing base 4 Here, this interlocking end piece 11 ensures the training of the reduction transmission mechanism 9 acting on the maneuvering square 8, the assembly formed by the coupling end piece 11, this reduction transmission mechanism 9 and the maneuvering square 8 constituting, in this embodiment, the 'transmission member 7 controlled in rotation by the gripping member 2.

According to the invention also, the interlocking means 10 are associated with resilient return locking means 13 in the locking position 14 to axially immobilize the gripping member 2 on the fixing base 4.

Preferably, these resiliently return locking means 13 are defined to be able to be elastically pushed back into an unlocked position during engagement of the gripping member 2 on the fixing base 4 to be returned to the elastically locking position. at the end of engagement in order to prevent this axial displacement of the gripping member 2 relative to said fixing base 4.

In the illustrated embodiment, the elastic return locking means 13 are pushed back into an unlocked position at the time of engagement of the engagement sleeve 12 on the engagement end cap 11.

Substantially, the elastic return locking means 13 are defined by at least one elastic thread 15 fitted, as the case may be, to the gripping member 2 or the fixing base 4 which, during this interlocking is pushed back under elastic stress in an unlocked position, favoring this interlocking. In contrast, in the nested position, this elastic thread 15 is defined capable of elastically engaging under a retaining rim 16, in the manner of a keeper, to ensure this function of axial locking of the gripping member 2 on the mounting base 4.

More particularly still, according to an embodiment visible in the drawing, in particular in the figures 2 and 6 , the elastic thread 15 takes the form of a pin 17 fixedly mounted on the fixing base 4 in a plane substantially perpendicular to the interlocking axis 5. This pin 17 comprises two strands 18, 19 elastically separated one relative to the other at the time of engagement of the engagement sleeve 12 on the engagement end piece 11 for, at the end of engagement, as illustrated in figures 3 and 5 , engage under a retaining rim 16 defined by a groove or groove portions 21, 22 formed on the periphery of the interlocking sleeve 12.

It should be noted that in the case of an inverted assembly consisting in equipping the fixing base 4 with a fitting sleeve, the latter may include at its peripheral wall, through grooves, so as to allow the strands 18, 19 of the pin 17 to cooperate with the fitting end piece corresponding to the gripping member 2 and coming to be inserted in this fitting sleeve of the fixing base.

As seen illustrated in figures 1 and 6 , the fixing base 4 is crossed, perpendicularly to its application plane 6, by openings 22, 23 for passage of fixing members 24, in this case fixing screws as visible in the figure 6 . These therefore make it possible to fix this fixing base 4 and, consequently, the handle device 1, on a joinery.

Advantageously, said elastic return locking means 13 are fixedly attached to the fixing base 4 by means of these fixing members 24.

More particularly in the illustrated embodiment showing these resiliently return locking means 13 in the form of a pin 17, the latter is positioned in the housing grooves 25 which the fixing base 4 comprises, on the front face 26 opposite to the application plane 6. The pin 17 comprises the extensions 27, 28, coming to be housed in this adapted housing groove 25 extending around the openings 22, 23 for the passage of the fixing screws 24. Thus, the head of these fixing screws allows these extensions 27, 28 of the pin 17 to be fixed in this groove 25 around the openings 22, 23, while preserving the strands 18, 19 the elastic mobility necessary to ensure their mobility between a function of locking and a function allowing the engagement, or even the disengagement of the gripping member 2.

In a complementary manner, the fixing base may further comprise retaining flanges 39 on the periphery of its front face 26, retaining flanges 39 ensuring better retention of the resilient return locking means 13, in particular near the sleeve of interlocking 12, so as to offer additional attachment security vis-à-vis forces that would be applied substantially in the direction of axis 5.

The handle device 1 according to the invention also comprises a means 29 for concealing the fixing members 24. Such means 29 not only contributes to the aesthetics of the fixing base 4, but, in addition, prevents access. direct to the latter, in particular by an uninformed operator.

Advantageously, this concealment means 29 is in the form of a cover box 30 which covers at least the front face 26 of the fixing base 4.

Preferably, this cover box 30 further extends externally to this fixing base 4 along the peripheral wall 31 of the latter. Thus, the cover box 30 itself comprises a front face 32 at the periphery of which extends a lining wall 33.

Advantageously, said cover box 30 comprises clipping means 34 able to cooperate with complementary clipping means 35 that the fixing base 4 comprises to ensure the nested retention of the cover box 30 on the latter. Substantially, the clipping means 34 are in the form of a hooking rim 36 fitted internally and at the end edge of the lining wall 33, so as to cooperate with a recess 37 forming the complementary clipping means provided at the base of the peripheral wall 31 of the fixing base 4.

According to the invention, the concealment means 29 further defines locking means 38 of the elastic return locking means 13 in the locked position.

Preferably, this concealment means 29 performs this role of blocking means when it is in the concealed position on the fixing base 4. In short, this blocking function is performed by the cover box 30 once fitted. on this mounting base 4.

Thus, the covering box 30, more particularly its lining wall 33 is defined capable, once the covering box 30 has been fitted onto the fixing base 4, to cooperate with the strands 18, 19 of the pin 17 defining said resiliently return locking means 13, to maintain these strands 18, 19 in their locking position 14, that is to say engaged in the groove portions 20, 21 which the interlocking sleeve 12 comprises. Under these conditions , these strands 18, 19 have insufficient play to extract themselves from these groove portions 20, 21 and prevent any disengagement of the interlocking sleeve 12 by contribution to the interlocking end piece 11, therefore of the member grip 2.

On the contrary, and as the figure 4 , when the cover box 30 is not in its snapped position on the fixing base 4, its lining wall 33 offers sufficient play to these strands 18, 19 of the pin 17 to allow them to move away one from the other and extract themselves from these groove portions 20, 21. In this case, these resiliently return locking means 13 are capable of leaving the locking position 14 which results, not only, in the possibility of the aforementioned disengagement, but also the mounting by axial interlocking of the gripping member 2 on the fixing base 4. Note that this additional play provided by the locking wall 33 with respect to the arms 18, 19 of the pin 17 may result from the cooperation of the hooking rim 36 of this lining wall 33 with the peripheral wall 31 of the fixing base 4, before its engagement under the recess 37 located at the base of this peripheral wall 31 of the 'fixing base 4. Indeed, this hooking rim 36 extending inside urement the cover casing 30 externally pushes this lining wall 33 by providing the clearance necessary for the desired function.

This hooking rim 36 can be chamfered on its side corresponding to the direction of engagement of the cover box 30 on the fixing base 4, this to promote this engagement, or even on the opposite side to allow the release, preferably. with a certain resistance, resulting in the possibility of removing the gripping member 2 if necessary.

The advantages resulting from the present invention consist in that the fixing base of the handle device can be attached to a carpentry independently of the gripping member that this handle device comprises.

Likewise, the cover box 30 which obscures the fixing base by preventing access to the latter while contributing to the aesthetic character of the handle device is also capable of being mounted in a second step on this fixing base. so that, together, the gripping member, in this case the crutch or the control button, and the cover box 30 can be preserved from any soiling, being capable of being attached in a second step, with great ease and without the use of tools, on the mounting base 4.

Conversely, the cover casing 30 and the gripping member 2 can be removed or even replaced subsequently for maintenance or aesthetic reasons, without however requiring the complete dismantling of the fixing base.
