Description

DOOR HANDLE AND WINDOW FOR QUICK ASSEMBLY AND REMOVAL WITHOUT TOOL.

TECHNICAL AREA

The present invention relates to the field of handles for opening, for example for doors or window doors, windows or any other equivalent opening.

STATE OF THE ART

We have already proposed many handle structures for opening.

Generally the sets of opening handles, in particular of doors or French windows comprise two handles (sometimes called half handles or crutches) made integral with a square axis which cooperates with the nut of the nut of a closing mechanism. The two handles are placed respectively on one side, for example outside, of the opening, and on the other side, inside, of the opening, to allow the operation respectively from the outside and from the inside. Typically in known devices a first handle is made integral with the square axis in a non-removable manner, for example by force fitting, by gluing or by overmolding, while the second handle is removably fixed by a radial screw engaged in the body of the second handle and the end of which bears on the square axis. Certain sets of sash handles, in particular for windows, comprise a single handle, generally placed on the interior side. Their design remains broadly identical to the above description, namely that the handle is made integral by any appropriate means with a square axis which cooperates with the nut of the nut of the closing mechanism.

The installers and users have long expressed the wish to have means making it possible to facilitate the installation of a handle and / or the removal of handles, for example for maintenance purposes.

A strong demand is in particular to have structures allowing the installation and the removal of handle without requiring any particular tool.

Examples of known handles can be found in documents US 2006/0202491, EP 2 961 899, DE 10 2013 205 061, FR 3 047 759, US 3 891 253, CN 106988609, CN 206071267U, EP 0 770 745, EP 1 201 850, EP 2 241 704, EP 2 476 823, EP 2 562 330, EP 3 203 000, FR 1 191 818, FR 2 650 322, FR 2 766 858, JP 44187128, SE 532954, US 1,743,955, US 2,520,669, WO 2012/045702, WO 2017/068504 and US 2010/0225129.

Some of these known devices make it possible to improve the situation.

However, none of the known devices are completely satisfactory. In particular, the known devices require a tool to disassemble the handle. This constitutes a strong constraint. PROBLEMS POSED AND BASIS OF THE INVENTION

FIG. 1 shows a handle assembly comprising a first handle 10, a second handle 20 and a square axis 30.

FIG. 2 shows an assembly mechanism 100 according to the invention designed to provide the connection between the handle 10 and the axis 30.

This handle assembly is designed to be placed on an opening, such as a door, a French window, a window or any other equivalent opening.

The square axis 30 is adapted to cooperate with the nut follower of the opening mechanism of the opening.

The handles 10 and 20 can be the subject of numerous embodiments. They comprise a body 12, 22 adapted to be engaged on a respective end of the axis 30.

When the handle, for example 20, is designed to be fixed permanently to the square axis 30, the body 22 has a blind central bore of square cross section complementary to the axis 30.

When the handle, 10 for example, is designed to be fixed to the square axis 30 by means of an assembly mechanism 100 in accordance with the present invention, the body 12 has a central blind housing 16 adapted to receive this mechanism 100.

Without this embodiment being limiting, the housing 16 of the handle body 12 illustrated in FIG. 7 comprises three successive cylindrical sections of revolution 17, 18 and 19 having respective diameters increasing in the direction of the opening of the housing

16.

The handles 10, 20 can be of the button type or of the stand type. In the latter case, as can be seen in the appended figures, each handle comprises a lever 14, 24 secured to the body 12, 22 and oriented radially with respect to the axis of the body 12, 22.

At least one of the two handles 10 and 20 is assembled on the square axis 30 using an assembly mechanism 100 according to the present invention, illustrated in FIG. 3, allowing rapid installation without tools. of this handle on the axis 30 and allowing the same quick and tool-free removal of this handle.

Where appropriate, the two handles 10 and 20 can be assembled on the square axis 30 using a respective assembly mechanism 100.

However, preferably one of the handles, in this case the second handle 20, is made integral, without any planned disassembly, with the axis 30.

The handle 20 and the axis 30 are secured to this end by any suitable means.

The handle 20 and the axis 30 can for example be secured by means of a needle screw passing through the body 22 of the handle 20 and making it possible, once tightened, to exert a pressing force on one of the 4 faces of the axis 30. This pressure of the needle screw head on the square axis 30 provides a mechanical connection suitable for linking the handle 20 and the axis 30. The handle 20 and the axis 30 can be secured by any other means, for example by an assembly by fitting, gluing or by overmolding.

We will now describe the assembly mechanism 100 according to the present invention, illustrated in FIGS. 1 to 9.

The function of this mechanism 100 is to allow the handle 10 to be installed and secured in translation and in rotation, on the axis 30, without any tool.

This mechanism 100 is also adapted to allow rapid and tool-free disassembly of said handle 10, in order to extract the latter from the axis 30, which ultimately makes it possible to disassemble the subassembly.

The mechanism 100 comprises, as illustrated in FIG. 3:

A driver 110 intended to be mounted integral with the body 12 of the handle 10 and having a cylindrical bore 112 passing through with a diameter greater than the diagonal of the square axis 30,

A cam 130 which can slide along the square axis 30, A torsion spring 150 and

A washer 170 provided for example with 2 or 4 tongues or lamellae cooperating by contact with the square axis 30.

The aforementioned elements making up the assembly mechanism 100 according to the invention are stacked axially in the following order from the bottom of the housing 16: the washer 170, the spring 150, the cam 130, then the driver 110.

The driver 110 has the general shape of a ring centered in use on the axis 0-0 of the square axis 30. It is fixed integrally in the first section 17 of the housing 16 arranged on the end of the body 12 of the handle 10. The method of fixing the driver 110 in the housing 17 can be the subject of numerous embodiments. It may for example be a fixing using at least one connecting screw (not shown) housed both in a radial bore 11 formed in the body 12 of the handle and in an imprint 111 fitted on the exterior surface of the driver 110.

The driver 110 can also be fixed in the housing 17 for example by fitting, by gluing or any other method of assembly making it possible to secure the driver 110 to the main body 12 of the handle 10.

The driver 110 integrates on its axial face 113 directed towards the cam 130 and on which the cam 130 is supported, a biasing structure 114 adapted to bias the cam 130 in translation along the axis 0-0 during a relative rotation between the driver 110 and the cam 130. To this end, said axial face 113 of the driver 110 diverges at least partially with respect to a radial plane perpendicular to the axis OO. More precisely, said axial face 113 of the driver 110 has at least one structure 114 inclined with respect to a radial plane perpendicular to the axis O-O. This structure 114 can be a ramp or a pin or finger extending axially along the axis O-O. Preferably, several structures 114 are distributed equally around the axis 0-0 to center the resulting stressing force exerted on the cam 130, on the axis O-O.

According to the preferred embodiment illustrated in the appended figures, the driver 110 has, on its face 113, two diametrically opposite shapes 114 extending axially along the axis O-O. The end of each of the two shapes or protrusions 114 is of curved profile to limit the contact area between the driver 110 and the cam 130 and thus limit the frictional resistance forces during a relative rotation between the cam 130 and the 'coach 110 with sliding contact between them, as will be seen later.

More precisely still according to the particular embodiment illustrated in the appended figures, the driver 110 has the general shape of a ring composed of two cylindrical sections of revolution juxtaposed axially: a first section 117 whose outer diameter is complementary to the internal diameter section 17 of the housing formed in the body 12 of the handle 10 and a second section 118 of smaller outside diameter.

It will also be recalled that the driver 110 has a central cylindrical bore passing through 112 with a diameter greater than the diagonal of the square axis 30 so that the driver 110 does not interfere with the square axis 30.

The first section 117 has the function of ensuring a rigid mechanical connection, without possible displacement in translation or rotation between the driver 110 and the handle body 12 by any appropriate means (as indicated previously for example by screws, bonding, fitting or any other assembly method)

The second cylindrical section 118 which extends the driver 110 on its side opposite to the shapes 114 and is substantially coaxial with the direction 0-0 of the square axis 30 allows, by being housed in the bore of a fixed centering component on the opening and aligned in the direction 0-0 of the square axis 30, to limit the functional clearances thereby forming a rotary bearing function.

As illustrated in FIG. 9, the cam 130 is formed of a generally cylindrical body which extends along the axis 0-0. More precisely, preferably the cam 130 comprises, juxtaposed axially along the axis 0-0, a first cylindrical section 132 of large diameter adjacent to the driver 110 and a second section 140 of smaller diameter directed towards the washer 170.

The cam 130 has an internal housing 131 crossing a square cross section complementary to the external section of the axis 30 which cooperates with the square axis 30 so as to transmit an actuating torque in rotation to the nut of the nut of the mechanism d 'opening. The cam 130 can therefore slide axially along the square axis 30.

The cam 130 has on its section 132 adjacent to the trainer 110 structures defining on the one hand a radial stop function adapted to ensure, in a direction of rotation of the handle 10 and therefore of the trainer 110, a drive to rotation of the cam 130 around the axis 0-0 and on the other hand a translational biasing function of the cam 130 along the axis 0-0 during a controlled rotation movement of the handle 10 in the direction opposite.

The outside diameter of the section 132 is complementary to the inside diameter of the housing section 18, but with sufficient play to allow a relative movement in rotation between the cam

130 and the body 12 of the handle 10 while ensuring rotational guidance of the cam 130 in the housing 18.

More precisely still the section 132 of the cam 130 has on its axial face 133 directed towards the driver 110, structures 134 complementary to the stressing structures 114 provided on the driver 110 and adapted to stress the cam 130 in translation along the axis 0-0 during a relative rotation between the driver 110 and the cam 130. To this end, said axial face 133 of the cam 130 diverges at least partially with respect to a radial plane perpendicular to the axis OO. More precisely, said axial face 133 of the cam 130 has at least one structure 134 inclined relative to a radial plane perpendicular to the axis O-O. Preferably, several structures 134 are distributed equally around the axis 0-0 in number and according to an angular distribution identical to the structures 114 of the driver 110, to center the resulting stressing force exerted on the cam 130, on the 'OO axis. These structures 134 shown in the appended figures are formed by ramps which diverge progressively from the axial face 133 with respect to the radial plane perpendicular to the 0-0 axis of this axial face 133. By way of non-limiting example, the ramps 134 each have an angular opening of the order of 90 ° around the axis OO.

Each ramp 134 ends at its end furthest from the axial face 133 by a facet 135 oriented along a radial plane parallel to the axis 0-0 and which serves as a stop for the protuberances 114 of the coach for training when the cam 130 rotates when said protuberances 114 urge these facets 135.

The cam 130 thus preferably has two oblique bearing paths 134 cooperating by sliding contact respectively with the shapes 114 of the driver 110.

Thus, a relative movement in rotation between the handle 10 and the square axis 30 in a first direction of rotation carrying the protrusions 114 of the driver 110 bearing on the facets 135 of the cam 130 (in FIG. 5 this relative rotation of the handle 10 is referenced A) tends to drive the cam 130 and therefore the axis 30 to rotate in the same direction as the handle 10 to actuate the closing system of the opening.

Furthermore and conversely a relative movement in rotation between the handle 10 and the square axis 30 in a second direction of rotation opposite to the first (in FIG. 5 this relative rotation of the handle 10 is referenced B) results in a relative rotation between the driver 110 secured to the handle 10 and the cam 30. This relative rotational movement displaces the shapes 114 along the oblique support paths 134 which generates a relative translation of the cam 30 relative to the driver 110 along the axis 30. This translation tends to bring the cam 130 closer to the washer 170 so that the cam 130 urges the washer 170 as will be seen later.

The washer 170 is housed in the bottom of the cavity 16 arranged in the main body 12 of the handle 10.

It forms a blocking element suitable for engaging with the axis 30 by an elastic force and ensuring a mechanical connection between the handle 10 and the axis 30.

More specifically, the washer 170 is housed in the housing section 18 and bears by its outer periphery against the recess 15 formed between the two housing sections 18 and 19.

This washer 170 is preferably made of high elastic limit steel, of the spring steel type.

As illustrated in FIG. 6, the washer 170 comprises an external ring 171 which has on its radially internal periphery a plurality of lamellae 172 distributed equally around the axis OO, directed towards this axis, preferably in a number identical to the number of facets of the axis 30. As a variant, the washer 170 can be provided with only two diametrically opposite blades 172 intended to cooperate with two opposite faces of the square axis 30.

The washer 170 thus preferably has four strips 172 extending radially inwards, that is towards the faces of the square axis 30. The internal contour of the four strips 172 of the washer 170 preferably defines a contour of square shape complementary to the section of the axis 30. Any other shape is allowed as long as it ensures at rest a mechanical connection between the washer 170 and the axis 30.

The outside diameter of the washer 170 is complementary but slightly less than the diameter of the cylindrical cavity 18 provided in the main body 12 of the handle 10 so that the housing 16 does not apply stress to the washer 170.

At rest the distance separating the free ends of two diametrically opposite blades 172 is less than the width of the axis 30, that is to say the distance separating two diametrically opposite faces of this axis 30. Thus when the washer 170 is engaged on the axis 30, the washer 170 engages and in mechanical connection with the axis 30. However, as will be seen later, when the blades 172 are biased in deformation, they can move apart and release the axis 30.

The strips 172 can be flat and located in a radial plane perpendicular to the axis O-O. However, preferably, they are curved and when the washer 170 is installed in the bottom of the cavity 16 arranged in the main body 12 of the handle 10, the curvature of said strips 172 is oriented towards the bottom of the cavity 16 arranged in the body 12. In other words, preferably the free ends of the strips 172 converge towards the bottom of the blind housing 16 formed in the body 12 of the handle 10.

The assembly mechanism 100 according to the present invention also preferably comprises an elastic member 150 which urges the cam 130 to rest against the driver 110 at rest.

This elastic member 150 can be the subject of numerous embodiments.

According to the preferred embodiment illustrated in the appended figures, in particular in Figure 8, the elastic member 150 is formed of a torsion spring.

This torsion spring 150 preferably comprises a main part composed of at least one active turn 152, and two ends 154 and 156 each ending in a strand of the spring steel wire constituting the torsion spring 150.

More precisely still according to the preferred embodiment illustrated in the appended figures, a first end 154 of the spring 150 extends in a radial direction towards the outside with respect to the axis OO, while the second end 156 extends axially with respect to the axis 0-0 towards the outside of the turns 152.

The torsion spring 150 is engaged on the section 140 of the cam 130 and is placed in the section 18 of the housing 16 of the handle.

At rest, the outside diameter of the spring 150 is less than the inside diameter of the housing 18, while its inside diameter is greater than the outside diameter of the section 140 of the cam 130.

When installing the torsion spring 150 in the housing 18 arranged in the main body 12 of the handle 10, the radial end 154 is housed in a groove 13 in the housing 18 arranged axially parallel to the axis 0-0 on the entire length of the housing 18, while the axial end 156 is housed in a blind groove 136 arranged in the cam 130, on the outer periphery of the section 132 and leading to the recess 137 formed between the two sections 132 and 140. The diameter of the spring wire, the number of turns and the average diameter of the turns are the main characteristics which determine the torsional stiffness of the spring 150 expressed in Nm / deg.

Thus, during a relative movement in rotation of the handle 10 relative to the axis 0-0 in a controlled direction of the movement of rotation, the shapes 114 slide along the oblique profiles 134 which results in a distancing, of the cam 130 relative to the driver 110. This “controlled” direction of rotation preferably corresponds to the opposite direction to that required for actuating the closing device of the opening.

At the same time, the torsion spring 150 is stressed and stores deformation energy. When the torque allowing the relative rotational movement is canceled out, the torsion spring 150 releases the stored energy, which has the consequence of creating a reverse relative rotational movement and of bringing the cam 130 towards the driver 110. This movement of relative reverse rotation is limited by the stops 135 of the cam 130 and the shapes 114 of the driver 110, when said shapes 114 come to bear against the stops 135.

According to the arbitrary representation given in the figures, the relative direction of rotation of the handle 10, relative to the axis OO, to ensure the actuation of the closing device of the opening (which carries the forms 114 in support and in stressing relationship with the stops 135) corresponds to the direction referenced A in FIG. 5. This direction corresponds to the trigonometric direction, that is to say the anticlockwise direction if the handle 10 is observed along the axis OO, from the trainer 110.

Consequently, the reverse “controlled” direction of rotation of the handle 10, adapted to allow the handle 10 to be disassembled corresponds to the direction referenced B in FIG. 5. This direction corresponds to the clockwise direction, if the the handle 10 is observed along the axis OO, from the trainer 110.

The active turns of the spring 150 can be wound in a clockwise or anti-clockwise direction according to the methods adopted to limit the amplitude of the rotation authorized to ensure the disassembly of the handle, that is to say according to whether the 'It is desired to limit this amplitude by pressing the external diameter of the spring 150 on the internal surface of the housing 18 or by pressing the internal diameter of the spring 150 on the external surface of the section 140 of the cam 130, as will be seen below.

The cam 130 has on its end opposite to the driver 110, that is to say on its end adjacent to the washer, a stressing structure 142 of reduced diameter, adapted to stress the strips 172 during a drive to translation of the cam 130.

More precisely, the outside diameter of this stressing structure 142 is less than that of the ring 171 of the washer 170 and preferably preferably equal to half of the radial extension of the strips 172 so that the stressing structure 142 is supported. on the slats 172, substantially mid-length thereof.

More precisely still, preferably the biasing structure 142 comprises a plurality of spouts 144 equally distributed around the axis OO, in a number identical to the number of lamellae 172, and positioned opposite the lamellae 172 of the elastic washer 170. Each spout 144 is surrounded by two axial extensions 146, the spacing of which is complementary to the width of the strips 172. The extensions 146 allow the strips 172 and the cam 130 to be indexed in angular position, so that the spouts 144 are positioned opposite slats 172.

When the nozzles 144 urge the blades 172 in deformation, by translation of the cam 130, the curvature of the blades 172 is accentuated and the free end of the blades 172 is distant from the square axis 30. The washer 170 is thus separated from the square axis 30 and is no longer axially linked to this square axis 30. The handle 10 can then be removed axially relative to the square axis 30.

When the components of the mechanism 100 of the handle 10 are assembled, the spring 150 plates, by virtue of its elasticity of compression, the washer 170 on the bearing face 15.

We will now describe the rapid assembly process of the handle 10, without tools, on the square axis 30, according to the present invention.

When mounting the handle 10 on the square axis 30, as seen on examining Figures 4 and 5, the assembly mechanism 100 according to the invention, comprising the washer 170, the elastic member 150 , the cam 130 and the driver 110, is positioned in the housing 16 of the handle, and the driver 110 is immobilized in this housing 16, as indicated previously, for example using a needle screw or any other equivalent means. The axial position of the driver 110 is controlled so that the washer 170 is sandwiched between the bearing face 15 formed in the housing 16 and the elastic member 150, with only the minimum clearance required to allow the deformations of the slats 172 between a working position in which the slats 172 are in resilient engagement with the faces of the square axis 30 and a release position in which the slats 172 are spaced from the axis 30 to release the latter. It is thus understood that the washer 170 is immobilized axially between the bearing face 15 and the elastic member 150.

To mount the handle 10 on the square axis 30, we then proceed as follows:

the square axis 30 firstly crosses the bore 112 of the driver 110,

then the square axis 30 is introduced into the square bore 131 of the cam 130 on which the elastic member 150 is prepositioned,

- Then the square axis 30 crosses the washer 170, the slats 172 being dimensioned so that they slightly resist crossing the square axis 30, which has the consequence of slightly elastically deforming in the direction of their curvature the slats 172.

During this insertion, the slats 172 have a curvature such that they are inclined in the direction of an inclination relative to a radial plane perpendicular to the axis 0-0 so that their free ends move away from the cam 130 in approach of the axis OO.

As soon as the assembly movement on the square axis 30 stops, the slats 172 of the elastic washer 170 in contact with the square faces of the square axis 30 oppose any movement of reverse translation of the axis square 30 vis-à-vis the elastic washer 170, the strips 172 behaving like claws engaged with the faces of the axis 30. The washer 170 can also not move back and move away substantially from its face d 'support 15 because the dimensions of the elastic member 150 and of the other components are such that the blades 172 are limited in their axial movement.

If necessary, a retaining ring of the Circlips type (not shown) or the equivalent can be installed so as to block in translation along the axis OO, the washer 170 once installed bearing on the face 15. Such a ring stop can be accommodated and positioned in a groove arranged in the cavity 16 of the main body 12 of the handle 10.

Thanks to the aforementioned device in accordance with the present invention, it is possible to install the handle 10 without any tool in any position relative to the square axis 30.

As previously indicated once installed on the square axis 30, the handle 10 is axially blocked by fixing the washer 170 on the axis 30, the washer 170 being moreover trapped axially between the face of support 15 and spring 150 and the entire assembly mechanism being immobilized axially in the housing 16.

To actuate the closing device of the opening, it suffices then to drive the handle 10 to pivot in the direction A such that the elements 114 of the driver 110 bear on the stops 135 and urge them.

We will now describe the process of rapid disassembly of the handle 10, without tools, relative to the square axis 30, according to the present invention.

We have just seen that the washer 170 opposes any reverse movement in translation of the square axis 30, after installation of the handle 10 on said axis 30.

If a torque is exerted on the handle 10 causing a relative rotational movement between the axis 30 and said handle 10, in a controlled direction of rotation B opposite for example the rotational movement A of actuation of the handle 10 for actuating the opening mechanism, the cam 130 is urged away from the driver 110 and therefore closer to the washer 170. This rotational movement B of the handle 10 generates a translational movement of the cam 130 .

The cam 130 thus moves in the direction of the washer 170 and the torsion spring 150 is biased and stores energy. The spouts 144 of the cam 130 push the inner end of the strips 172 of the washer 170 which has the effect of deforming them elastically. This elastic deformation spreads the inner edges of the slats 172 relative to the faces of the square axis 30 which frees the grip of said slats 172 which prevented any movement of reverse translation of the axis 30 in order to extract the square axis 30 of the handle 10. By maintaining the relative rotation of the handle 10 relative to the axis 30, the spacing of the inner edges of the strips 172 is maintained with respect to the faces of the square axis 30, which makes it possible to extract the square axis 30 from the handle 10 by pulling on the handle 10.

Once disassembled, the handle 10 can again be installed along the square axis 30 because the strips 172 of the washer 170 have returned to their initial free shape and the energy stored by the torsion spring 150 during the rotational movement relative allowing to release the grip of the slats 172 on the square axis 30 and to extract the handle 10 brings the cam 130 back to its initial position relative to the driver 110 by a relative rotational movement opposite to that exerted to extract the handle 10 of the square axis 30. This reverse relative rotation movement brings the stops 135 of the cam 130 towards the shapes 114 of the driver 110.

In the context of the invention, the assembly mechanism 100 preferably comprises means limiting the angle of movement of the handle 10, in particular in the direction of rotation of the handle 10 intended to ensure disassembly without tools.

According to a preferred embodiment, these means for limiting the angular movement of the handle 10 are formed by the spring 150.

It has previously been established that the active turns of the spring 150 can be wound clockwise or anti-clockwise and are preferably positioned on the section 140 of the cam 130.

Depending on the direction chosen, the relative rotational movement of the handle 10 and therefore of the spring 150 making it possible to release the strips 172 for disassembly of the handle 10, will have the effect of urging the torsion spring 150 by increasing or decreasing its mean diameter.

Depending on the diameter of the housing 18 in which the spring 150 is placed, if it is assumed that the stress on the spring 150 is in the direction of an increase in its diameter, the relative rotational movement is limited to a maximum angular value when the external diameter of the turns of the spring 150 thus deformed have the same value as the internal diameter of the bore 18 of the housing 16. It is thus advantageous to limit the relative angle of rotation to avoid too great a displacement movement of the cam 130 and therefore excessive deformation of the strips 172 which is not necessary, from the moment when the strips 172 are sufficiently deformed by the spouts 144 of the cam 130 to release the grip of the elastic washer 170 on the faces of the square axis 30.

According to a second embodiment of the torsion spring 150, the relative rotational movement making it possible to release the blades 172 with a view to dismantling the handle 10 has the effect of urging the torsion spring 150 by reducing its mean diameter. Depending on the diameter of the part 140 of the cam 130 surrounded by the turns of the torsion spring 150, the relative rotational movement is limited to a maximum angular value when the internal diameter of the turns of the spring 150 thus deformed has the same value as the diameter of the part 140.

When assembling the components forming the mechanism 100 of the handle 10, it is preferable that the components are angularly oriented so that the handle 10 can be installed on the square axis 30 in coherence with the alignment of the handle 10. This preferred angular orientation is obtained by angularly positioning the driver 110 relative to the body 12 of the handle

10. Thus, the cam 130 is correctly oriented, and more particularly its inner bore 131 of square section, because the torsion spring 150, the two ends of which are engaged with the cam 130 and the groove 13 arranged in the main body 12 of the handle 10 forces a relative angular position between the cam 130 and the driver 110, by means of the stops 135 and the shapes 114.

The components of the assembly mechanism 100, namely the driver 110, the cam 130, the elastic member 150 and the washer 170, can be made of any suitable material.

We will indicate below possible and preferential materials, but in no way limiting.

As examples:

. the trainer 110 can be made of steel, aluminum alloy, copper alloy, or plastic, which allows component 110 to be produced by injection using a mold.

. the cam 130 can be made of steel, aluminum alloy, copper alloy, or plastic, which also allows it to be produced by molding.

. the torsion spring 150 can be made of steel with high elastic limit, such as for example piano wire. The torsion spring 150 can also be produced with high elastic limit steel wire with rectangular section.

. the elastic washer 170 can be made of steel with high elastic limit.

. the body of the handle 10 can be made of molded aluminum alloy, molded copper alloy, steel or even plastic.

The handle body 12 10 is generally a part with style requirements. It can be polished, sanded, or coated with a layer of paint, or coated with a protective layer against oxidation.

According to another advantageous characteristic of the invention, to facilitate the installation of the mechanism 100 in the housing 16 of the main body 12 of the handle 10, it is advantageous to group and mount the components forming the mechanism, namely the washer 170, l the elastic member 150, the cam 130 and the driver 110, in an envelope 182 forming an installation cartridge 180 as seen in FIGS. 10 and 11.

The cartridge casing 182 illustrated in FIGS. 10 and 11 comprises a cylindrical body of revolution whose external diameter is complementary to the internal diameter of a corresponding housing 16 formed in the body 12 of the handle 10 to enable this cartridge to be engaged 180 in said body 12.

The envelope 182 comprises means adapted to receive the end 154 of the spring 150 and to prevent the rotation of this end 154 of the spring 150. To this end the envelope 182 preferably comprises at least one opening 184 in the form of light parallel to the axis OO, in which the end strand 154 of the torsion spring 150 is housed. This opening 184 serves as a radial stop to block any rotational movement of the end strand 154.

The casing 182 preferably comprises on each of its two ends radial means or narrowing serving as an axial stop respectively for the washer 170 and for the driver 110.

More precisely still preferably as illustrated in the appended figures, on its end adjacent to the washer 170, the casing 182 comprises a flange 186 directed radially towards the axis 0-0 which forms the bearing surface 15 for the washer 170 .

The envelope 182 further comprises on its opposite end, means 190 making it possible to fix the driver 110 in an axial and radial position in the envelope 182.

These means 190 can be the subject of numerous variant embodiments. They are preferably formed from predefined legs by stamping in the body of the casing 182 and folded into the appropriate working position, after installation of the components, washer 170, elastic member 150, cam 130 and driver 110, in the casing 182, to serve as a lock for the driver 110.

To this end, the casing 182 preferably comprises two series of tabs or tabs 192, 194 stepped axially on the body of the casing, equally distributed around the axis 0-0 on the body of the casing 182 and intended to be placed on either side, axially of the driver 110.

The casing 182 may for example comprise a first series of at least two tabs 192 diametrically opposite on the body of the casing 182, which cooperate by contact with the face of the driver 110 directed towards the cam 130, these tabs 192 serving as an axial stop to this face of the driver 110. The lugs 192, which extend initially in the thickness of the material of the envelope, but are individualized by precut, with the exception of a zone preserved from articulation, are put in place by folding in a radial plane perpendicular to the axis OO, after having inserted the washer 170, the torsion spring 150 and the cam 130 in the casing 182 of the cartridge 180.

These tabs 192 may be tongues folded back by bending using a suitable tool as illustrated in FIG. 11, or else any other shape obtained by deformation and allowing axial stops to be obtained for the driver 110.

Advantageously, the lugs 192 can be folded down in corresponding complementary housings 120 arranged in the driver 110. More precisely still the housings 120 are oriented radially so that they serve as indexing and angular locking of the driver 110 on the body of the envelope 182.

The envelope 182 may also comprise a second series of at least two tabs 194 folded down by folding in a radial plane perpendicular to the axis 0-0 on the end of the envelope 182 after installation of the driver 110 in the cartridge 180. These tabs 194 once folded immobilize in relative translation the driver 110 in the cartridge 180. Advantageously, these tabs 194 can be housed in complementary corresponding cavities 122 arranged in the coach 110. More precisely still the cavities 122 are preferably oriented radially so that they also serve as indexing and angular locking of the driver 110 on the body of the casing 182 so as to block any movement of relative rotation of the driver 110 relative to the cartridge 180.

These tabs 194 can be produced by bending using a suitable tool. These tongues 194 can also take any other form making it possible to immobilize in translation and / or in relative rotation the trainer 110 installed in the cartridge 180.

Preferably, the two series of legs 192 and tongues 194 are angularly offset relative to each other, by half the angle separating the legs and tongues between them.

The envelope 182 of the cartridge 180 can be made of steel, or made of a metallic material allowing the production of the lugs 192 and tabs 194 serving as axial and radial stops by deformation or bending, or in any other suitable material, for example in material plastic by providing on the body of the envelope elastic projections designed to elastically disappear when the components are engaged, washer 170, elastic member 150, cam 130 and driver 110, in the envelope 182, while taking up thereafter their rest position adapted to immobilize the driver 110 axially and radially.

The sub-assembly 180 consisting of the cartridge and the components, washer 170, elastic member 150, cam 130 and driver 110, installed in the cartridge (31) can advantageously be installed as a single unit in the housing 16 of the body 12 d 'a handle 10. This housing 16 may advantageously be cylindrical, like the external shape of the cartridge 180. Its cylindrical dimensions complementary to the casing 182 of the cartridge 180 allow either an assembly by tight fitting, or an assembly by gluing or any other appropriate equivalent means.

The square section housing 131 arranged in the cam 130 through which the square axis 30 can translate when the handle 10 is mounted can be used to index the cartridge sub-assembly 180 in angular position relative to the body of the handle 10.

Of course the present invention is not limited to the particular embodiments which have just been described but extends to any variant in accordance with its spirit.

There is illustrated in the appended figures an embodiment comprising two handles 10 and 20. The invention however also applies to implementations comprising a single handle 10 equipped with the assembly mechanism 100, associated with a square axis 30 , for example for controlling a window.

The torsion spring 150 can be replaced by a compression spring interposed between the recess 137 formed on the cam 130 and the washer 170. Such a compression spring can return the cam 130 to the rest position close to the driver 110, y understood by exerting on the cam a return torque in rotation if the slope of the ramps 134 is sufficient.

Furthermore, the arrangement of the protruding shapes 114 on the driver 110 and of the ramps 134 on the cam 130 can be reversed. In other words, it is possible to provide ramps similar to the ramps 134, on the coach and conversely projecting pins or fingers similar to the shapes 114, facing the cam 130.

Furthermore, the protruding shapes 114 can be replaced by ramps placed opposite the ramps 134 by adapting the materials and surface condition of the respective areas in contact, on the driver 110 and on the cam 130 to limit the forces resistant by friction.

As indicated previously, the present invention can also be applied to a single handle for window as soon as the square axis on which the handle is fixed using the assembly mechanism 100 is made integral with the nut of the nut of the mechanism. closing.
