Description

The present invention relates to a control handle for door, window or the like, especially in carpentry metallic, in particular of the type known as opening knock tilt-and-turn or French-style.

In the usual door closers or classic window of this type, one generally implements a cremone bolt actuated by a control mechanism housed at the inside of a profile of the opening of this door or window, this cremone bolt comprising rods or the like suitable for slide opposite the sash to protrude or retract out of or into the profile at its ends, generally high and low, if necessary lateral, when penetrating or clearing of reception housings provided in the fixed frame in relation to which the opening struggles.

The cremone bolt control mechanism is usually operated by a handle which projects outside of opening it in one of its faces, being mounted in the central part of the corresponding profile and which transmits the movement causing opening or closing by through the cremone bolt, following a rotation relative of this handle, of the type comprising in particular a spout cane or even of the kind said to espagnolette.

In practice, the handle has a body allowing its rotary operation, which is extended by a rod, usually square section, this rod entering the profile by a drilling thereof to come cooperate with a housing or a teeth of the same profile provided in the actuation mechanism of the cremone bolt, mounted inside the profile.

The arrangement of a conventional handle of this kind requires, in usual rule, the drilling of three holes, on the front of the outwardly profiled therefrom in the mounting region of the handle, respectively for the passage of the rod extending the body of the latter and for the establishment screws for immobilizing a support or base, inside which can rotate the rod, which drives by its square section the movement of the cremone bolt as mentioned above, the control mechanism being mounted in a housing inserted in a profile housing by the side thereof. The heads of screws can then be concealed by an appropriate cover, covering or extending from the support.

An improvement to such an assembly consists in designing and to use a handle that is snap-on, so that it can be easily installed or removed from the profile. Indeed, when the doors or windows are transported from their place of manufacture to the site of construction where they are to be used, the prominence of the handle is a disadvantage since it prevents to apply the frames against each other.

It is therefore desirable that the handle can be removable and that the operator who ensures the installation of these doors or windows, makes the adaptation itself on these from the handle, which requires that the latter has a simple and quick fixing system. A handful snap-in meets these goals, further eliminating the use of fixing screws.

We already know various realizations of handles snap-in for doors or windows in metal joinery.

In general, known systems are designed in such a way that the handle rod has a transverse bore for mounting a locking ball or the like, in particular of the kind of a pawn extending laterally with respect to the rod, subjected to the thrust of a spring so that it can be erased in its housing or to protrude outside of it, to allow or otherwise prevent the removal of the rod vis-à-vis the profile into which it enters in order to actuate the cremone bolt control mechanism.

In this case, however, unlocking the handle requires to provide in the side of the profile an opening through which a tool can have access to the locking ball or pin for allow its erasure in the housing of the rod provided for this effect, by releasing the handle which can be removed with the rod by a displacement in the direction thereof.

Other variants have already been envisaged, comprising a device fitted with a washer mounted on the handle and suitable for index the movement of the latter with a drive member integral with the cremone bolt, a return spring arranged coaxial to the rod between the handle body and the support or the base against which it is applied, allowing move the rod and access the locking ball above to escape the latter and release the rod and the handle. However, in this case, it is still necessary to provide means of access for a tool through the profile acting on the ball.

In another case, provision has also been made to produce the rod in two coaxial parts, one being in engagement with the actuation mechanism of the cremone bolt, the other with the body of the handle, before these parts are aligned and secured together by a snap-in system. However, besides the higher cost of such a device and its assembly more complex, we also encounter difficulties in quickly and easily separate the handle from the profile.

The present invention relates to a removable handle, in particular by snap-fitting, suitable for carrying it out by a very simple operation, which can be carried out by the user himself, the assembly being adaptable to any type cremone bolt and requiring no specific tool to ensure erasing the locking ball against its spring.

To this end, the handle considered, of the type comprising a operating body, provided axially with a rod capable of penetrating through a passage opening of practically the same cross-section as the rod, provided in a profile of the opening of a door or window, the end of this rod being arranged to come in grip, when the handle is applied against the profile, with a mechanism mounted in a housing housed inside the profile for actuating a cremone bolt, opening or closing of the movable opening relative to a fixed frame, the rod comprising a transverse locking pin subjected to the action of a thrust spring so as to project towards outside the rod or to fade into it against of this spring in order to allow the opening of the orifice passing through this pin when the handle is put in place, before this pin, inside the profile, comes back in protrusion from the rod to prevent its withdrawal in the direction reverse, and a positioning base, of general shape cylindrical, arranged opposite the passage opening on the side outside of the opening and crossed in its center by the rod, this base fitting at the end of the body of the handle which can nevertheless turn in it to activate the cremone bolt, is characterized in that the base includes means suitable for locking it in rotation relative to the profile and in that the handle comprises, on the one hand an intermediate washer, having a bore of the same section as the rod which cross member, housed in the base and subjected to the effect of a spring compression which applies it against the bottom of the base, itself resting against the profile, the washer and the base comprising in their facing faces, a dog clutch system suitable for limiting the rotation of the operating body and the rod carrying the washer, transmitted to the lever, and on the other hand a removable locking stop, carried by the base, suitable for modify the possible travel of the operating body in translation along the axis of the rod against the compression spring, the end of the rod being, as the case may be, engaged with the mechanism for actuating the lever or released from it, the rod and the body then being free to rotate.

In a preferred embodiment of the invention, the rod integral with the operating body has a common part of circular cross section and has a key at its end training or similar, able to come and cooperate with a homologous form provided in the actuation mechanism of the cremone bolt, the running part and the end of the rod being separated by a smaller cross-section area.

Preferably also and in the same embodiment, the case containing the cremone actuation mechanism is adapted so that, depending on the axial position of the rod, this mechanism either engages with the drive key or released from it when the connection zone is brought to the right: of this mechanism.

According to another characteristic, the transverse pawn of rod lock is mounted in a blind housing, formed perpendicular to it and against the bottom of which is applied the thrust spring which rests opposite on a shoulder supported by the pawn, exerting an effort to make protrude it out of the outline of the rod.

Advantageously, the transverse pin is associated with a ring holding, cylindrical, crossed by the rod and disposed at right of the pawn, which engages at its projecting end in an opening provided in the ring, which holds the pin trapped in the rod housing by its shoulder.

According to another characteristic also, the base of positioning has a circular counterbore in its face opposite the intermediate washer, this counterbore being adapted to receive the cylindrical retaining ring which can freely turn with the rod relative to the base.

Preferably, the removable locking stop carried by the operating body is constituted by a transverse screw, in particular of the grub screw type controlled by a key called "Allen", which cooperates with a tapped hole provided laterally in the positioning base so as to bring its end a sufficient distance inside this to constitute a scope on which is based the end of the operating body.

Also preferably, the rod is secured in permanence of the operating body by means of another screw transverse fixing carried by the body and which comes to block the end of the rod which enters a suitable cavity of the body.

• Figures 10 to 12 are similar views explaining how the handle can be disassembled after its installation, without requiring the intervention of any particular tool.

Referring to Figures 1 to 4, we see that the handle considered, designated as a whole under the reference 1, comprises an operating body 2, here substantially in shape cylindrical, extended by a transverse extension 3 forming cane spout, to control the rotation of this handle.

The body 2 has at its end opposite the spout 3 a cylindrical shell 4 delimiting an internal housing 5 in which is mounted a compression spring 6, spiral, supported against a transverse bearing 7 of the body 2 in the bottom of the housing 5. The latter has, along the axis of the handle, a shoulder part 8 in the center of which an axial hole 9 is provided intended to receive the end 10 of a rod 11, extending thus the body 2.

The end 10 of the rod 11 engages inside the hole axial 9, the rod and the body 2 then being secured one to the other by a lateral screw 12, which opens into the hole 9 and forcibly immobilizes the rod previously pressed into it.

The operating body 2 is also associated with a positioning base 13, which has an external flange 14 suitable for coming around the cylindrical shell from the outside 4 of the body when the parts are mutually assembled, as shown in Figure 4.

In the bottom 15 of the base, a passage 16 is provided, substantially the same section as the main part 17 of the rod 11, so that it can freely cross the base. This also includes in the face of the bottom 15 opposite to body 2 a circular counterbore 18, of slightly straight cross section greater than that of the current part 17 of the rod and of which the role will be explained later.

Opposite the counterbore 18, the bottom 15 of the base 13 comprises a ring 19, which is provided with a dog clutch system the notches 20 and the intermediate recesses 21 are distributed over the periphery of this ring at 90 °, as shown schematically the sectional view of Figure 3.

The dog clutch system of the ring 19 is designed to cooperate with an intermediate washer 22, itself having notches 23, this washer being disposed in the housing 5 of the body 2 and having, on the one hand an internal bore 24 for the passage of the rod 11, having for this purpose substantially the same section than this, and on the other hand a bearing surface 25 for the compression spring 6.

The main part 17 of the rod also includes a transverse locking pin 26, which is mounted in a blind housing 27 provided in the rod perpendicular to its axial direction, at a suitable location depending on the length of this one so that once the various elements of the handle 1 assembled together as shown in the Figure 4, the pin 26 is disposed slightly behind the bottom 15 of the base 13, projecting towards the outside of the rod.

The locking pin 26 is hollow and has a cavity 28 in which a small return spring 29 engages, in opposite support against the bottom of the housing 27 so as to permanently exert an effort on this pawn, tending to push back towards the outside of the rod 11.

To prevent the pawn from escaping, however, and ensure its retention in its housing, the rod 11 is associated with a cylindrical ring 30, the diameter of which is determined for it allow to come to style the stem by disposing to the right of the pin, which advantageously comprises a lateral flange 31 coming to cooperate with the corresponding surface 32 of the ring 30, while the pawn's head can freely pass through a hole 33, thus coming to be exposed outside of the latter, as shown in Figure 2.

The outside diameter of the ring 30 is moreover determined so that in the position of use of the handle, it is applied in the circular counterbore 18 at the bottom 15 of the base, thus ensuring the guidance of the rod.

The handle is completed with a screw 34, mounted in a threaded hole 35 of the external flange 14 of the base 13, this screw, preferably of the headless screw type and command by Allen key, being provided to overflow at the inside of the collar, opposite the end of the ferrule 4 of the body 2, constituting a stop for the latter transverse, limiting the maximum displacement of this body in direction of the base, the role of this stop being specified in the rest of the description.

Opposite the operating body 2, the rod 11 has a profiled end 36, playing the role of a key, here in the form of square and whose maximum transverse dimension is however at most equal to that of the current part 17 of the rod, of so that this end can safely cross the passage 16 of the base 13 when the rod is put in place through it.

The key 36 and the main part 17 of the rod 11, which preferably has a square section, are joined by a connecting zone 37, also of circular section.

The handle 1 comprising, as described above, the body of operation 2, the rod 11, the base 13 and the intermediate washer 22, is provided, once established, to act on a mechanism 38 for actuating a cremone bolt, in itself good known in the art, and of which Figure 5 illustrates by way of very schematic example of the structure.

This mechanism 38 includes a housing 39 in which is housed a pinion 40 having an axially through bore 41, having the profile of a nut and whose shape and counterpart of that of the key 36 provided at the end of the rod 11, here in profile square, this pinion 40 being arranged to cooperate with teeth, 42 and 43 respectively, provided opposite on bars 44 and 45, adapted accordingly to slide one by compared to the other vis-à-vis the case 39, but in opposite directions, so that these bars can emerge or disappear in a profile of the door leaf or window, allowing their engagement or withdrawal vis-à-vis keepers provided in the corresponding frame, to opening or closing the opening.

Figures 6 to 8 on the one hand, 10 to 12 on the other hand, allow to explain how the handle thus produced is respectively placed in the section 46 of the opening the door or window, with automatic locking of this handle thanks to the locking pin 26, then possibly removed by erasing this pawn and allowing the extraction of the rod, without the intervention of any additional tool.

In these Figures, the essential elements of the handle described above and also illustrated the profile 46 of the opening on which it must be mounted, this profile comprising an internal structure 47 suitable for enabling support and immobilization of the housing 39 containing the mechanism the cremone bolt, as briefly described more high.

Also in these Figures, it can be seen that the base of positioning 13 has a lateral extension 48, which is arranged to cooperate with a surface 49 similarly contour of profile 46 so that when the handle is in place, the base is locked relative to this profile and in particular cannot rotate with the handle.

The section 46 comprises a fabric 50 with an orifice passage 51, the diameter of which corresponds to that of the ring cylindrical holding 30, so that it can cross this orifice, from the inside to the outside of the profiled, when the pin 26 is completely erased in the ring, the projection of this pawn on the other side of the canvas preventing normally removal of the rod.

Firstly and as illustrated in Figure 6, the handle with its various parts assembled according to Figure 4, is approached from the section 46, the key 36 then the current part of the rod 11 passing freely through the orifice 51 provided in the canvas 50.

The movement continues until the key 36 begins to engage the nut 41 of the actuation mechanism 38 of the cremone bolt, housed in case 39. At this instant, the pawn of lock 26 is present in front of orifice 51 and is gradually brought to fade in the housing 27 of the rod 11, to facilitate it to continue its movement. Advantageously, the head of the pin 26 is rounded for him allow this gradual erasure.

In Figure 8, the rod movement continued until the end of the ferrule 4 of the operating body 2 inside the flange 14 of the base 13 comes to the contact of the stop formed by the locking screw 34 carried by the latter. At this instant, the key 36 protrudes very slightly of the housing 39, while remaining in engagement with the nut 41 of the actuation mechanism 38. Simultaneously, the lock 26 which has passed the opening 51 of the fabric 50, is relaxes under the pressure of the spring 29 and protrudes again the outside of the ring 30.

In the final phase of putting the handle in place, the thrust force on it is interrupted, the spring of compression 6 slightly pushing back the body 2, while the wrench 36 remains engaged with nut 41. The locking pin 26, who relaxed in the previous phase, comes up against behind the fabric 50 and consequently blocks the handle in position.

To operate the handle 1 and control by the rod 11 the actuation mechanism 38 of the cremone bolt, the cane beak 3 so that it drives both the rod 11 which controls the nut 41 and the intermediate washer 22 of which the notch 23 cooperates with the dog clutch system 20, 21 of the ring 19, causing a slight recoil of this washer, absorbed by the compression spring 6.

When the handle has rotated 90 °, the notch of the washer is next to the following recesses of the ring, by performing a conventional indexing of the handle according to the aforementioned angle. During this rotation, the base of positioning 13 is immobilized by its extension 48 which does not can rotate relative to the facing surface 49 of the profile 46. On the other hand, the intermediate washer 22 is permanently applied to the ring 19 thanks to the spring 6.

When you finally want to remove the handle, it suffices to the user to remove by a simple Allen key the screw of blocking 34 to extract it from its bore 35.

Under these conditions, the ferrule 4 of the handle 22 can be pushed deeper into base 13, the stroke thus offered being sufficient for the key 36 at the end of the rod 11 escapes the nut 41, leading to inside of it the lower link area 37 diameter. The rod 11 can then rotate freely, independently of the actuating mechanism 38, so that that the ring 30 and the locking pin 36 pivot again 90 °, or 180 ° vis-à-vis the position illustrated on the Figure 10, arranging as shown in the Figures 11 and 12.

In this position, the locking pin 26 is at again retracted inside the ring 30 by pressing on a facing 52, provided inside the section 46, the ring integral with the rod 11 which can then be extracted in passing through the opening 51 of the fabric 50.

This produces a very snap-on handle device simple and which in particular has a reduced bulk, this which allows it to be easily mounted on a low profile section. The only machining required in the latter corresponds to the realization of the orifice 51 which is constituted by a simple hole, usually circular, corresponding to the diameter of the rod 11.

The handle can be assembled in one operation and requires no fixing. Finally, the handle can be removed with a simple release screw, forming limit stop, mounted on the base and dismantling is both simple and can be done too quickly as needed.
