Description

DESCRIPTION

Handle device, in particular for a door or window

The invention relates to a door, window or similar handle device comprising a gripping member, in the form of a latch, button or similar, rotatably mounted on a fixing base for rotary control of a transmission member, in particular of a drive spindle, said fixing base comprising means for receiving fixing members such as screws or rivets.

The present invention relates to the field of construction hardware and relates, more particularly, to handle devices for doors, windows or any other carpentry work in construction.

Many handle devices for doors, windows or the like corresponding to the above description are already known. Thus, usually, such a handle device comprises a gripping member which most often takes the form of a latch or a button, comprising a shaft through which this latch or this button is securely mounted. rotatable on a fixing base intended to be placed in a carpentry work, consistent with the control mechanism of a closing fitting intended to be controlled by this handle device.

To this end, the latch or the button most often act on a drive spindle to transmit a rotation command to this locking hardware mechanism. Normally, this drive spindle cooperates with a follower comprising this mechanism.

In addition, if this mechanism is generally installed in the groove of the carpentry work, which includes a through opening to the right of the passage of the drive square, the handle device that acts on the latter is usually placed leaning against the inner side, depending on the outer case, in the carpentry work. For this reason, the fixing base comprises openings for the passage of fixing members, more particularly fixing screws.

Different concealment means are currently implemented to conceal these fixing members, either for aesthetic or safety reasons, preventing, for example, the unscrewing of these fixing members.

As concealment means, the use of covers that close the housings provided in the fixing base to receive the heads of the fixing screws is already known. However, it is very easy to misplace such caps during an operator's intervention on the handle device, not to mention that skill and dedication must be demonstrated in assembling and installing these caps. Furthermore, the integration of such covers automatically imposes aesthetic options, which are by nature debatable, since such covers must remain visible and easily accessible to the end user.

Another known solution consists in rotatingly mounting a cover plate on the fixing base. Thus, when the latter pivots transversely with respect to the fixing base, it makes the head of the fixing screws accessible for, depending on the case, their tightening or loosening. On the contrary, remembered in an alignment position on this fixing base, this cover plate completely hides these fixing screws.

Furthermore, in this hidden position, this cover plate is elastically pushed back to a locking position preventing any inadvertent rotation. In fact, only under the action of a traction exerted on this cover plate, against the action of the elastic return means, is it capable of crossing such a locking position and therefore pivoting in an arrangement that favors access to the screws. Fixing.

First of all, the equipment of such a cover plate handle device is particularly restrictive. This team must intervene at the time of manufacturing the handle device, remembering that the gripping member is permanently mounted in rotation on the fixing base. Furthermore, this irreversible pre-assembly of the rotatable gripping member on the fixing base is a source of additional difficulties in equipping 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 from a closed position to an open position. This manipulation is accompanied by a check on the closing hardware to which the handle device is associated. However, it may be necessary to prevent such control of the closing hardware from necessarily resulting in the closing or opening of the door or window while it is being assembled in a building.

Furthermore, said cover plate as a means to hide the fixing members, induces restrictive limits to the aesthetic character that a fixing base can assume. Finally, such a cover plate may require, for its pivoting, a limited space requirement for the frame to be equipped, in particular in terms of width and profile shape.

An important drawback deriving from these solutions corresponding to the prior art is that said handle devices placed immediately to a door or window installed in a building under construction or renovation are exposed to the risk of getting dirty and deteriorating, due to the intervention of other trades, such as drywall installers, painters or others. A second great inconvenience is that of imposing, long before the delivery of the carpentry works, the choice of the shape and colors of the handles.

Furthermore, in order to prevent such a handle device, whose aesthetic character is particularly important, from being modified even before the construction is finished, the carpenter is tempted to postpone equipping doors or windows with a handle device during this construction phase. to proceed with this equipment only at the end of the work. However, this is hardly conceivable to the extent that it is often necessary to manipulate these openings that constitute these doors or windows to facilitate or simply allow the intervention of other trades.

It should be taken into account that it is already known through the state of the prior art represented by documents US2007/170731, WO2004/090268, DE1703318 and DE29511544 handle devices, whose gripping member can be placed in rotation to the fixing base of retractable form, which makes it possible to previously equip said doors or windows with the fixing bases of such handle devices at the time of installation of the joinery in a building under construction, without subsequently exposing the gripping member to damage. Especially during the construction site, it is possible to equip a handle device with a site gripping member, thanks to the detachable character

The handle device described in document DE29511544 comprises a means for concealing the fixing members of this fixing base that take the form of a cover box that can be nested on this fixing base. It should be noted that this handle device according to document DE29511544 comprises closing means with elastic return in the retention position to axially immobilize the gripping member of this handle device on a fixing base. This further comprises means for locking the elastic return closing means in the closed position. These locking means are placed under the elastic return means and are unlocked by means of a tool after having removed the concealment rosette from the fixing means.

Thus, the two elements that contribute to the aesthetic character of the handle device, i.e. the end grip member and this cover box, are likely to be placed in a joinery at the end of the work, i.e. when the risk of damage is reduced and the aesthetic decisions of the end user are made. Furthermore, this approach also leads to the possibility of being able to reconsider these options during the lifetime of the product, by means of a simple and quick replacement of the grip member and the cover box, without however requiring a complete disassembly of the handle.

In a novel approach, it has also been conceived that this means of concealment of the fixing members of the fixing base, more particularly the cover box in the preferred embodiment of the invention, contributes to securing the pivoting assembly of the grip member in this mounting base.

To this end, the invention relates to a handle device, in particular for a door or window, comprising a grip member in the form of a latch, button or the like, pivotally mounted on a fixing base for control of rotation of a transmission member, in particular of a drive square, said fixing base comprising means for receiving fixing members, such as screws or the like, as well as means for concealing these means for receiving fixing members , the concealment means is presented in the form of a cover box covering at least the front face of the fixing base, the grip member is rotatably mounted on the fixing base by means of engagement along its direction axial pivot defined by an assembly formed by a socket connector and a coaxial socket sleeve, one of which equips the fixing base, the other, the grip member, and n said engagement means associated with the locking means with elastic return in retention position to axially immobilize this gripping member on this fixing base, the handle device further comprises means for locking the closing means with elastic return in position closed, characterized in that these blocking means are defined by means of concealment of the means for receiving the fixing members on the fixing base.

The advantages resulting from the present invention consist in the fact that the gripping member of the handle device can be placed on the fixing base by simple snapping, its retention being ensured by means of closing with elastic return.

In addition, the locking of these closing means with elastic return in the closed position makes it possible to prevent the involuntary displacement of this gripping member.

Advantageously, this cover box can come to be equipped with this fixing base at the same time that the gripping member performs a locking function as indicated above. The perceptible external aesthetics, after assembly, of this cover box can be totally independent of this function.

Other particular characteristics of the invention and the advantages derived from them will become apparent during the description that follows relative to an example of embodiment given by way of indication and not limitation.

Understanding this description will be facilitated by consulting the attached drawings, in which:

[Figure 1] is a partial schematic representation in perspective of a handle device according to the invention;

As illustrated in the figures of the attached drawings, the present invention refers to a handle device 1 intended, more particularly, for carpentry works such as doors, windows or the like.

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

This gripping member 2 is rotatably mounted on a fixing base 4 intended to be placed resting on a carpentry work, for example on a door or window leaf.

In a very general way, 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 said carpentry work.

The gripping member 2 has the purpose of ensuring the rotation of a transmission member 7 intended to act on the mechanism of a closing hardware such as a lock, espagnolette, espagnolette-lock or other. Such a transmission member 7 often takes the form of a drive square 8 as illustrated in particular in Figure 2.

It should be noted that the present invention is in no way limited to a direct interaction of the gripping member 2 on said drive square 8.

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

Other solutions can also be conceived, without the invention being limited in any way to such an interaction between the gripping member 2 and this transmission member 7.

Particularly to the invention, the gripping member 2 is rotatably mounted on the fixing base 4 by means of engagement means 10 in the axial pivoting direction 5 of the gripping member 2.

Said coupling means 10 are defined by an assembly formed by a coupling connector 11 and a coaxial coupling sleeve 12, one of which equips the fixing base 4, the other the grip member 2.

In the embodiment illustrated in the drawings, the gripping member 2 comprises the socket sleeve 12 which engages in the socket connector 11 which equips the fixing base 4. However, a reversal of this construction is quite conceivable.

In such a context, the socket connector 11 or the socket sleeve 12 comprising the fixing base 4 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 partly transmission member 7.

In short, the gripping member 2 equipped, as the case may be, with a socket sleeve 12 as illustrated in the drawings or with a socket connector can pivot around the socket connector 11 or the socket sleeve fixedly mounted on it. the fixing base 4 or pivot together with this socket connector 11 or this socket sleeve rotatably mounted on this fixing base 4.

In the embodiment shown, the gripping member 2 comprises a socket sleeve 12 which fits over a socket connector 11 to drive the rotation of the latter, which is also rotatably mounted on the fixing base 4. Here, this socket connector 11 drives the transmission mechanism by gears 9 acting on the drive spindle 8, the assembly formed by the socket connector 11, this transmission mechanism by gears 9 and the drive spindle 8 constitute in this embodiment the member of transmission 7 controlled in rotation by gripping member 2.

Also according to the invention, the engagement means 10 are associated with the closing means with elastic return 13 in the locking position 14 to axially immobilize the gripping member 2 on the fixing base 4.

Preferably, these elastic return closure means 13 are defined capable of being elastically pushed back to an open position during mounting of the gripping member 2 on the fixing base 4 to return to the elastic closure position at the end of the engagement for prevent this axial displacement of the gripping member 2 with respect to said fixing base 4.

In the illustrated embodiment, the spring-back closure means 13 is pushed back to an open position upon engagement of the socket sleeve 12 in the socket connector 11.

Substantially, the elastic return closure means 13 are defined by at least one elastic thread 15 that equips, depending on the case, the gripping member 2 or the fixing base 4 which, during this engagement, is pushed back under elastic tension in an open position, favoring this fit. On the contrary, in the engaged position, this elastic thread 15 is defined as being able to elastically engage under a retaining rim 16, such as a striker plate, to ensure this axial locking function of the gripping member 2 on the fixing base 4. Even more particularly, according to an embodiment visible in the drawing, in particular in 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 lace axis 5. This pin 17 comprises two threads 18, 19 elastically separated from each other at the moment of engagement of the lace sleeve 12 in the lace connector 11 for, at the end of the lace, as illustrated in figures 3 and 5 , engage under a retaining lip 16 defined by a slot or slot portions 21, 22 formed in the periphery of the engagement sleeve 12.

It should be noted that in the case of an inverted assembly consisting of equipping the fixing base 4 with an engagement sleeve, the latter may comprise, on its peripheral wall, through slots, so as to allow the threads 18, 19 of the pin 17 to cooperate. with the fitting connector corresponding to the gripping member 2 and which is inserted into this fitting sleeve of the fixing base.

As can be seen illustrated in figures 1 and 6, the fixing base 4 is traversed, perpendicularly to its application plane 6, by openings 22, 23 for the passage of the fixing members 24, in this case a fixing screw as is shown in figure 6. These therefore allow to attach this fixing base 4 and therefore the handle device 1 to a carpentry work.

Advantageously, said closure means with elastic return 13 are placed on the fixing base 4 by means of these fixing members 24.

More particularly, in the illustrated embodiment that shows these closure means with elastic return 13 in the form of a pin 17, the latter is positioned in the housing slots 25 that comprise the fixing base 4, on the front face 26 opposite the application plane. 6. The pin 17 comprises the extensions 27, 28, which are housed in this adapted housing slot 25 which extends around the openings 22, 23 for the passage of the fixing screws 24. Thus, the head of these fixing screws fixing allows these extensions 27, 28 of the pin 17 to be fixed in this slot 25 around the openings 22, 23, preserving the elastic mobility of the strands 18, 19 necessary to ensure their mobility between a closing function and a function that allows engagement , or even the disengagement of the gripping member 2.

In addition, the fixing base can also include retaining rims 39 on the periphery of its front face 26, retaining rims 39 that ensure better retention of the elastic return closure means 13, in particular near the socket sleeve 12, to provide additional latching security against forces that would be applied substantially in the 5-axis direction.

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

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

Preferably, this cover box 30 extends even towards the outside of this fixing base 4 along the peripheral wall 31 of the latter. Thus, the cover box 30 itself comprises a front face 32 on the periphery of which a lining wall 33 extends.

Advantageously, said cover box 30 comprises clamping means 34 capable of cooperating with complementary clamping means 35 that comprise the fixing base 4 to ensure that the cover box 30 remains engaged on it. Substantially, the clamping means 34 have the form of a hooking rim 36 that is fitted internally and on the final edge of the cladding wall 33, to cooperate with a projection 37 that forms the complementary clamping means provided at the base of the wall. peripheral 31 of the fixing base 4.

According to the invention, the concealment means 29 further define locking means 38 of the elastic return closing means 13 in the open position.

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

Thus, the cover box 30, more particularly its lining wall 33, is defined as capable, once the cover box 30 is fitted on the fixing base 4, of cooperating with the threads 18, 19 of the pin 17 that define said closing means with elastic return 13, to keep these threads 18, 19 in their locking position 14, that is to say coupled in the slot portions 20, 21 that the engagement sleeve 12 comprises. Under these conditions, these threads 18, 19 have insufficient space to be removed from these slot portions 20, 21 and prevent any disengagement of the socket sleeve 12 with respect to the socket connector 11, hence the grip member 2.

On the contrary, and as shown in figure 4, when the cover box 30 is not in its locked position on the fixing base 4, its facing wall 33 provides sufficient space for these strands 18, 19 of the pin 17 to allow them to move away from each other and to be extracted from these slot portions 20, 21. In this case, these closing means with elastic return 13 are capable of leaving the locking position 14, giving rise not only to the possibility of the aforementioned disengagement , but also to the assembly by axial fit of the gripping member 2 on the fixing base 4. It should be noted that this additional space provided by the blocking wall 33 with respect to the arms 18, 19 of the pin 17 may result from the cooperation of the engagement rim 36 of this lining wall 33 with the peripheral wall 31 of the fixing base 4, before its coupling under the projection 37 located at the base of this peripheral wall 31 of the fixing base 4. In In effect, this latching rim 36 extending towards the inside of the cover box 30 pushes this lining wall 33 towards the outside providing the necessary space 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 favor this engagement, or even on the opposite side to allow disengagement, preferably with some resistance, resulting in the possibility of withdrawing the gripping member 2 if necessary.

The advantages deriving from the present invention consist in that the fixing base of the handle device can be placed in a carpentry work independently of the grip member comprising said handle device.

Likewise, the cover box 30 that hides the fixing base, preventing access to it and contributing to the aesthetic character of the handle device, is also capable of being mounted later on this fixing base, so that, together, the grip member, in this case the latch or the control button, and the cover box 30 can be preserved from any dirt, being able to be placed later, with great ease and without the use of tools, on the fixing base 4.

On the contrary, the cover box 30 and the gripping member 2 can be removed or even replaced later for maintenance or aesthetic reasons, without, however, the complete disassembly of the fixing base being necessary.
