The securing device comprises a base plate 156, 171.

[0196] The first embodiment will now be described with reference to FIGS. 1 to 20.

[0197] According to the first embodiment, the handle assembly 100 can comprise a first single handle 110, in this case the handle assembly 100 is mounted blind on an opening leaf 200, or with a first handle 110 and a second handle 101 opposing the first handle 110, the first handle 110 and the second handle 101 being positioned on either side of the opening leaf 200.

[0198] FIGS. 1 to 20 illustrate the case in which the handle assembly 100 comprises a first handle 110 and a second handle 101.

[0199] FIG. 1 illustrates the different components of the handle assembly 100 according to the first embodiment. The handle assembly 100 comprises a square spindle 120, which in the case of a handle assembly 100 without a second handle 101 can already be fixed on the opening leaf. Moreover, the handle assembly 100 comprises an insert 130 and an adapter 140 comprising a main body 141 and a clamp 142. In the variant of the first embodiment illustrated in FIG. 6, the handle assembly 100 comprises the same components as the handle assembly 100 according to the first embodiment, and in addition comprises two roses 102 and two rose covers 103.

[0200] According to the first embodiment, the square spindle 120 has a relief 121 arranged directly on at least a part of its length, and configured to cooperate with a complementary relief 112. In the example illustrated in FIG. 1 according to the first embodiment, the relief 121 of the square spindle 120 is in the form of a rack extending longitudinally along the longitudinal axis X-X of the square spindle 120. The ridges of the relief each correspond to a given distance at which the first handle can be immobilized in translation, in its securing configuration. Depending on the thickness of the opening leaf 200 and on the locking mechanism of the opening leaf 200, the first handle 110 cooperates with the square spindle 120 over a given distance.

[0201] According to the first embodiment, the insert 130, illustrated in FIG. 2, is intended to be integrated in the inner volume of the recess 111 of the first handle 110, as will be seen in the remainder of the description. In the first embodiment, the insert 130 comprises at least one guide element 131 configured to cooperate with a complementary guide element 111b arranged in the inner wall of the recess 111 as illustrated in particular in the figures in cross section of the handle assembly according to the first embodiment. In this example, the guide element 131 is a pin and the complementary guide element 111b is a hollow shaped to receive said pin. Of course, the guide element 131 can take other forms such as a hollow or a rib or a groove and the complementary guide element 111b can complementarily have the shape of a pin or a groove, or a rib. Advantageously, the insert 130 is captive and immobilized in the inner volume of the recess 111. For example, the insert 130 can be embedded, riveted, inserted by force, etc. Moreover, it should be noted that the guide element 131 and the complementary guide element 111b are optional and may not be present.

[0202] In the first embodiment, the locking member 150 is arranged on the insert 130, on the inner wall of the insert 130. The locking member 150 is a notch intended to cooperate with a complementary locking member 151 of the spur type. The locking member 150 extends over a part of the circumference of the insert and forms with the complementary locking member 151 a bayonet fitting system. In addition, the inner wall of the insert 130 at least partially forms a progressive ramp 132 about an axis of revolution merged with the longitudinal axis Y-Y along which the insert 130 extends.

[0203] The adapter 140 illustrated in FIG. 3 comprises a main body 141 preferentially in the shape of a ring. The main body 141 comprises an inner cavity 143 adapted to the shape of the square spindle 120. The inner cavity 143 is preferentially a though cavity along a longitudinal axis Z-Z of the adapter 140. The complementary locking member 151 is positioned on the outer wall of the adapter and is in the shape of a projecting spur.

[0204] In the first embodiment, the complementary relief 112 of the recess 111 is arranged on the adapter 140. More particularly, the adapter 140 comprises a movable part 142 mounted in a removable manner on the main body 141 of the adapter 140, the complementary relief 112 being arranged on the movable part 142. The movable part 142 is configured to be mobile between a retracted position and an engaged position with respect to the main body 141. In the engaged position, the movable part 142 is under compression on the main body 141, the movable part 142 being connected to the main body 141 by at least one elastically deformable member 146, for example a spring.

[0205] The main body 141 of the adapter 140 comprises an opening 144 through which the complementary relief 112 is intended to project in an engaged position of the movable part 142. In addition, the movable part 142 comprises a bearing surface 142a opposite the complementary relief 112, the bearing surface 142a being shaped to cooperate with the ramp 132 of the insert 130.

[0206] According to the first embodiment, the adapter 140 comprises an elastically deformable portion 145 configured so as, in a first state, to be compressed by a portion of the insert as can be seen in FIGS. 14, 16, 18, 20, pressing on said elastically deformable portion 145 of the adapter 140, and in a second state, to be released in the insert 130 as can be seen in FIG. 20. In the first embodiment, the elastically deformable portion 145 comprises a spur. In a variant, the elastically deformable portion 145 can be a spring blade integrated in a groove 147 arranged in the adapter 140 as illustrated in FIG. 4.

[0207] In the first embodiment, the second handle 101 is mounted on the square spindle 120 on a side of the opening leaf 200 as illustrated in FIG. 9. This assembly can be permanent (crimping, pin, etc.) or removable (screwing, removable clip, etc.).

[0208] As shown in FIGS. 9, 13 and 14, on the other side of the opening leaf, the first handle 110 is pre-mounted by inserting into the recess 111, the insert 130 and adapter 140 assembly. Of course, it is possible that the insert 130 is already mounted in the recess 111. In this pre-mounted configuration, the movable part 142 of the adapter 140 is in retracted position with respect to the main body 141 of the adapter 140, as can be seen in FIGS. 9 and 13, 14. In addition, in this configuration, the first handle 110 has a first orientation in which the grip portion 113 of the first handle 110 is vertical. The movable part 142 is positioned on an affine position of the ramp 132 as can be seen in FIG. 13 and in FIG. 14.

[0209] In FIGS. 10, 15 and 16, the initial configuration of the first handle 110 is shown in which the first handle 110 can slide freely along the longitudinal axis X-X of the square spindle 120 over a distance determined by the relief 121 of the square spindle 120 and the complementary relief 112 arranged on the movable part 142. In this embodiment, the first handle 110 is mounted on the square spindle 120 until it abuts the opening 200, as can be seen in FIGS. 10 and 15.

[0210] When the square spindle 120 enters the inner cavity 143 of the adapter 140, the relief 121 and the complementary relief 112 are positioned facing one another without interlocking.

[0211] In FIGS. 11, 17 and 18, the first handle 110 is rotated in a direction of rotation, in this case in the clockwise direction. The movable part 142 moves on the ramp 132 and because of the shape of the ramp 132, the movable part 142 tends towards the engagement position and is compressed little by little towards the main body 141 of the adapter 140 so that the relief 121 of the square spindle 120 and the complementary relief 112 of the movable part 142 mate, this pairing making it possible to immobilize the first handle 110 in translation with respect to the square spindle 120.

[0212] In FIGS. 12, 19 and 20, the first handle is in the securing configuration: the first handle 110 is immobilized in translation with respect to the square spindle 120 and is immobilized in rotation with respect to the square spindle 120. In this configuration, the relief 121 of the square spindle 120 mates with the complementary relief 112, the movable part 142 being in an engagement position and compressed against the main body 141 so that the complementary relief 112 projects with respect to the opening 144 arranged in the main body of the adapter 140. In addition, in this configuration, the locking member 150 cooperates with the complementary locking member 151 in order to immobilize the first handle in rotation with respect to the square spindle.

[0213] The set of steps detailed in FIGS. 9 to 20 are applicable to the variant of the first embodiment illustrated in FIGS. 6 to 8, an additional step of positioning the rose 102 and its cover 103 being carried out before the assembly of the first handle 110 on the square spindle 120, except in the case where the rose is secured with the handle 110 in particular by a resilient ring called a “circlip” upstream.

[0214] In a first variant of the first embodiment that is not shown, the movable part 142 can be in a single piece with the main body 141, the stroke of the movable part 142 and the return to position are obtained by the degree of freedom allowed by the resilient connection with the main body of the adapter 140.

[0215] In a second variant that is not shown, the insert 130 can be omitted and the shaped ramp 132 can be arranged directly in the recess 111 of the handle 110 and also the locking member 150.

[0216] In the first embodiment and all the variants described above, the movement in rotation of the first handle 110 can only be operated in a clockwise direction. In a third variant that is not shown, the movement of the first handle 110 in rotation can be performed in a clockwise direction or in an anticlockwise direction as a function of the opening on the right or the left of the opening leaf. To this end, in the third variant that is not shown, the ramp 132 is symmetrical and has a first end and a second end convergent towards a central portion, from the first end to the central portion the ramp descends and from the central portion to the second end the ramp 132 ascends. Moreover, the locking member 150, arranged on the insert 130, is enlarged radially so that the complementary locking member 151 abuts one side or the other of the locking member 150 allowing either locking in the clockwise direction or locking in the anticlockwise direction. Furthermore, the square spindle 120 must have at least two faces equipped with reliefs 121 in order to allow the catching of the complementary relief 112 of the clamp 142 on one side or the other of the square spindle 120 according to the assembly position.

[0217] The second embodiment will now be described with reference to FIGS. 44 to 55.

[0218] According to the second embodiment, the handle assembly 100 comprises a first single handle 110 mounted blind on an opening leaf 200.

[0219] FIG. 44 illustrates the different components of the handle assembly 100 according to the second embodiment. The handle assembly 100 comprises a handle 110, a square spindle 120, an insert 130, a pawl 152, a drive rod 153 of the pawl 152 and drive pin 154 of the drive rod 153.

[0220] According to the second embodiment, the square spindle 120 comprises a complementary locking member 151 directly arranged on its outer surface and intended to cooperate with a locking member 150 arranged on the insert 130.

[0221] The square spindle 120 according to the second embodiment has a transverse section that is globally circular except at least one end part 120a with a square or rectangular transverse section having a shape corresponding to the shape of the opening leaf mechanism 200 and more particularly to the follower of the opening leaf mechanism 200.

[0222] The square spindle 120 according to the second embodiment comprises a through orifice 122 extending longitudinally through the square spindle 120 and shaped to partially house a drive rod 153, as can be seen in FIG. 46 for example. The drive pin 154 is mounted to a first end of the drive rod 153 and is shaped to be housed in the first handle 110. The pawl 152 is mounted on the other end of the drive rod 153 and is shaped to pass through the follower 202 of an opening leaf mechanism 201. In this embodiment, the pawl 152 has a 45° angle in its locked position with respect to the square spindle of the follower 202, which allows the fastening of the first handle 110 to the opening leaf 200.

[0223] In addition, a spring 155 is arranged in the recess 111 of the first handle 110 and abuts against the drive pin 154, itself housed in the recess 111.

[0224] According to the second embodiment, the pawl 152 and the drive pin 154 are crimped on the drive rod 153. The drive pin 154 cooperates with a counter-shape provided in the first handle 110, but must remain free in translation to allow the engagement of the complementary locking member 151 in the locking member 150.

[0225] According to the second embodiment, the insert 130, illustrated in FIG. 45, is intended to be integrated in the inner volume of the recess 111 of the first handle 110, as will be seen in the remainder of the description. In the second embodiment, the insert 130 comprises at least one guide element 131 configured to cooperate with a complementary guide element (not shown) arranged in the inner wall of the recess 111. In this example, the guide element 131 is a pin and the complementary guide element is a recess shaped to receive the pin. Of course, the guide element 131 can take other forms such as a hollow or a rib or a groove and the complementary guide element 111b can respectively have the shape of a pin or a groove, or a rib. In addition, it should be noted that the guide element and the complementary guide element are optional and may not be present.

[0226] In the second embodiment, the locking member 150 is arranged on the insert 130, on the wall of the insert 130. The locking member 150 is a notch intended to cooperate with a complementary locking member 151 of the spur type arranged on the square spindle 120. The locking member 150 extends over a part of the circumference of the insert 130 and forms with the complementary locking member 151 a bayonet fitting system.

[0227] In FIGS. 47 and 48 the handle assembly according to the second embodiment is illustrated assembled.

[0228] The method for assembling the handle assembly 100 according to the second embodiment will now be described with reference to FIGS. 49 to 55.

[0229] In a first step illustrated in FIG. 49, a base plate 156 is mounted on the opening leaf 200, the base plate 156 comprising at least one receiving orifice 157 of the first handle 110 and an outer lock 158 of the first handle 110. Preferentially, the base plate 156 is fastened on the opening leaf 200, the receiving orifice 157 being arranged opposite the follower 202 of the mechanism 201 of the opening leaf 200 and the outer lock 158 of the base plate 156 is in the unlocked position.

[0230] In a variant that is not shown, a spring is placed between the base plate 156 and the first handle 110 so as to maintain the locked position of the locking members 150, 151.

[0231] In a second step illustrated in FIG. 50, the first handle 110 is brought towards the assembled base plate 156. The pawl 152, and optionally, a portion of the square spindle 120 pass through the follower 202 of the opening leaf 200. The pawl being in a passing position i.e. the square spindle 120 having faces coplanar with those of the pawl 152. In this second step, the grip portion 113 of the first handle 110 is oriented along an axis secant and non-perpendicular to an axis that is vertical and normal to the ground for example.

[0232] In a third step illustrated in FIG. 51, the first handle 110 is inserted into the opening leaf 200 through the base plate 156, so that: the pawl 152 passes through the follower 202 and beyond, the recess portion 114 of the handle 110 is placed flat against the opening leaf 200, in the receiving orifice 157, the spring 155 is compressed inside the recess portion 114 of the first handle 110.

[0233] In a fourth step illustrated in FIGS. 52 and 54, the first handle 110 is rotated about the axis of the square spindle 120 by an angle α, preferentially 45°, preferentially in an actuating direction of rotation of the handle, in this case in the clockwise direction. This rotation drives the rotation of the pawl 152 with respect to the follower 202, which remains fixed, so that the latter is in the catching position in which the pawl 152 can no longer leave the follower 202.

[0234] In a fifth step illustrated in FIG. 53, the first handle 110 is released so that the spring 155 is no longer compressed. By releasing the compression, the complementary locking member 151 of the square spindle 120 is housed in the locking member 150 of the insert 130. Following this release, the outer lock 158 of the base plate 156 is placed in the locked position. In this locked position, the outer lock 158 cooperates with a shoulder arranged on the insert 130 to immobilize the latter. In this locked position, the handle can no longer be placed flat against the opening leaf which has the effect of immobilizing the bayonet in its position and therefore of immobilizing the first handle 110 with respect to the opening leaf 200 as illustrated in FIG. 55.

[0235] Once these steps have been carried out, the first handle 110 is ready to be used to actuate the opening leaf 200 which can for example be a window. By rotating the first handle 110, the opening leaf mechanism 200 is driven and can allow the opening of the opening leaf 200 without coming away from the first handle 110. It can also allow other manipulations such as positioning in the tilt and turn position.

[0236] In a first embodiment of the securing device shown in FIGS. 56 to 76, the securing device includes the base plate 156, a lock 190, a contact surface 193. More particularly, the base plate 156 comprises a first portion 156a having a recess 156c shaped to house the lock 190 as illustrated in FIGS. 56, 57 and 58. The first portion 156a of the base plate 156 is intended to pass through the opening leaf 200 and project on a side of the opening leaf opposite the side of the opening leaf 200 where the first handle 110 is positioned, as can be seen in particular in FIG. 63. The base plate 156 comprises a second portion 156b in which the receiving orifice 157 of the first handle 110 is arranged.

[0237] In addition, the lock 190 is oblong in shape, comprising two diametrically opposed vanes 191, a clip 192 which is in the form of an elastically deformable bracket and arranged on one side of the lock between the vanes 191. The lock 190 comprises an inner lug 195 intended to cooperate with a portion of the contact surface 193 as can be seen in particular in FIGS. 67, 69, 71, 74 and 76.

[0238] In addition, the contact surface 193, shaped to be positioned in the lock 190 comprises a projecting stop spur 194 configured to cooperate in particular with the clip 192 in order to anchor the securing of the base plate 156 in the opening leaf 200. Advantageously, the contact surface 193 is secured to the square spindle 120.

[0239] The assembly of such a securing device will now be described with reference to FIGS. 59 to 76.

[0240] The base plate 156 can be inserted in two different ways illustrated in FIGS. 59 and 60. Either the base plate 156 is inserted directly in the opening leaf aperture 203 as illustrated in FIG. 59, or the base plate 156 is mounted on the first handle 110 and inserted in the opening leaf aperture 203 with said first handle 110 as illustrated in FIG. 60. Regardless of the way of inserting the base plate 156 in the opening leaf aperture 203, the first handle 110 must be oriented by an angle β with respect to a vertical line, the angle β being acute and preferentially approximately 45°, as illustrated in FIG. 61.

[0241] Once the base plate 156 is inserted and the first handle 110 positioned as illustrated in FIGS. 61, 62 and 63, the first handle 110 is rotated with respect to the square spindle 120, as illustrated in FIGS. 64 and 65, to secure the first handle 110 with the square spindle 120 and the square spindle 120 with the follower 201 (not shown), in the case of a window handle. The square spindle 120 as well as the contact surface 193 remain immobile as can be seen in FIG. 65. In this step, similar to the step shown in FIG. 52, the grip portion 113 of the first handle 110 is oriented vertically downwards, i.e. the free end of the first handle points towards the ground.

[0242] Then, the first handle 110 is again rotated by an angle, preferentially approximately 45°, upwards, the rotation of the first handle 110 driving the square spindle 120 and the contact surface 193 in rotation as illustrated in FIGS. 66 and 67. As can be seen in FIG. 67, by this new rotation, the stop spur 194 opens the clip 192 of the lock 190. Rotation in this direction continues, until the grip portion 113 of the first handle 110 is substantially horizontal as illustrated in FIG. 68. This continuing rotation allows the stop spur 194 to pass beyond the clip 192 of the lock 190 as illustrated in FIG. 69.

[0243] Then, the first handle 110 is rotated in the direction opposite to that previously used, so that the stop spur 194 drives the base plate lock 190 by means of the clip 192 until the vanes 191 abut respectively each against a portion of the base plate recess 156c as illustrated in FIGS. 73 to 75. The lock 190 then remains in place and secures the base plate 156 with the opening leaf 200. Finally, in normal use of the first handle 110 of the handle assembly 100, the lock 190 remains in place while opening and closing the opening leaf 200 as illustrated in FIGS. 74 and 76.

[0244] The securing device can cover two other embodiments illustrated in FIGS. 29 to 43. These two embodiments are described integrated in a return system 170 of the first handle but could be omitted from the return system.

[0245] In this case, the securing device according to these two embodiments would comprise and expansive base plate 171 and an expansion cam 172 as described with reference to FIGS. 29 to 43.

[0246] The third embodiment will now be described with reference to FIGS. 77 to 81.

[0247] The third embodiment differs from the first embodiment only in that the handle assembly 100 comprises a first handle 110 and a second handle 101 antagonist to the first handle 110, the first handle 110 and the second handle 101 being positioned on either side of the opening leaf 200. Thus, the catching of the first handle 110 by means of the pawl 152 no longer takes place behind the follower 202 as in the second embodiment but behind the square recess arranged in the opposite handle as illustrated in FIG. 81.

[0248] The remainder of the characteristics and in particular the components of the handle assembly 100 and their functions are identical to those of the second embodiment.

[0249] In FIG. 79, according to a first assembly step, the first handle 110 is placed against the opening leaf 200, the pawl 152 being aligned with the square spindle 120 and projecting with respect to the opening leaf and the opening leaf mechanism 201. The second handle 101 is placed opposite the pawl 152, on the other side of the opening leaf 200 with respect to the first handle 110. In this step, the first handle is raised by an angle preferentially equal to 45°.

[0250] In FIG. 80, according to a second assembly step, the second handle 101 is introduced so as to be fitted on the square spindle 120 projecting with respect to the opening leaf 200. The first handle 110 and the second handle 101 are brought to abut against the opening leaf 200 on either side of said opening leaf 200, the first handle still being raised, unlike the second handle 101, which has its grip portion horizontal, as illustrated in FIG. 80.

[0251] Following this second step, the first handle 110 is rotated in order to be realigned with the second handle 101, by an angle preferentially equal to −45°, so that the grip portion 113 of the first handle is horizontal as illustrated in FIG. 81. This rotation drives the rotation of the pawl 152 in the second handle 101 so that the latter has an abutment configuration in which it can no longer leave the second handle 101.

[0252] The fourth embodiment will now be described with reference to FIGS. 82 to 99.

[0253] The fourth embodiment differs from the first embodiment in that it comprises a catch system. The catch system of the handle assembly 100 according to the fourth embodiment is similar to that of the second embodiment.

[0254] The fourth embodiment differs from the second embodiment in that it comprises a system for adjusting the depth of the first handle by cooperation of the relief. The system for adjusting the handle assembly according to the fourth embodiment is similar to that of the first embodiment.

[0255] In the fourth embodiment, the handle assembly 100 comprises a first single handle 110 mounted blind on an opening leaf 200. Of course and according to a variant that is not shown, the handle assembly 100 according to the fourth embodiment can comprise a second handle 101, reference will be made to the assembly of the variant of the second embodiment applicable in this case.

[0256] In the fourth embodiment and as can be seen in FIG. 82, the handle assembly 100 comprises a first handle 110, an insert 130, a square spindle 120, a drive pin 154, a drive rod 153, a pawl 152 and a spring 155.

[0257] In the fourth embodiment, the square spindle 120 comprises a through orifice 122 as illustrated in FIG. 82, in which the drive rod 153 is housed. The drive pin 154 is arranged on one end of the drive rod 153 and the pawl 152 is arranged on the other end. The spring 155 is mounted on a portion of the square spindle 120 behind the pawl 152. In addition, the square spindle 120 according to the third embodiment comprises a relief 121 intended to cooperate with a complementary relief 112 positioned on the insert 130.

[0258] The square spindle 120 comprises a notch 161 arranged on an end receiving the drive pin 154.

[0259] The drive pin 154 comprises a spur 160 intended to be housed in the notch 161 in order to lock the square spindle mounted on the opening leaf 200.

[0260] The drive pin 154 is mounted mobile in rotation with respect to the square spindle 120.

[0261] In the fourth embodiment, the insert 130 comprises a receiving orifice 133 delimited by an inner wall 134. The receiving orifice 133 is intended to partially accommodate the square spindle 120 and the drive pin 154. The inner wall 134 of the insert 130 comprises two complementary reliefs 112a, 112b shaped to cooperate with the relief 121 arranged on the square spindle 120. In the example illustrated in FIG. 84, the two complementary reliefs 112a, 112b extend over a part of the circumference of the inner wall 134 of the insert 130 and over a part of the length of the insert 130. The first complementary relief 112a and the second complementary relief 112b are spaced apart from one another by a space without a relief 112c.

[0262] The insert 130 according to the fourth embodiment can comprise a guide element 131 cooperating with a complementary guide element 111b positioned in the recess 111 of the first handle 110, when the insert 130 is housed in the first handle 110.

[0263] The rotation of the handle on the square spindle 120 is limited by the stops 112d arranged on either side of the complementary relief or reliefs 112, 112a, 112b.

[0264] In a variant that is not shown, the inner wall 134 of the insert 130 comprises a single complementary relief 112 shaped to cooperate with the relief 121 arranged on the square spindle 120.

[0265] The method for assembling the handle assembly 100 according to the fourth embodiment will now be described with reference to FIGS. 86 to 99.

[0266] In a first step illustrated in FIG. 86, the base plate 156 is mounted on the opening leaf 200. This base plate 156 can be fastened by screwing or other means.

[0267] In a second step illustrated in FIG. 87, the mounted square spindle 120 is inserted in the opening leaf mechanism 201, through the base plate 156. In the present description, by “mounted square spindle” is meant the assembly of the square spindle 120, the drive rod 153, the drive pin 154 and the pawl 152 and the spring 155.

[0268] In a third step and as can be seen in FIG. 89, the spring 155 is compressed in order to cause the pawl 152 to project beyond the follower 202. Advantageously, the positioning of the mounted square spindle is carried out without tools. In this step, the pawl 152 is in the passing position and is thus aligned with the square spindle 120. A rotation of 45° of the drive pin 154 makes it possible to position the pawl 152 at 45° to the follower 202 and to allow the locking of the square spindle 120 mounted on the opening leaf 200. The spur 161 is housed in the notch 160 in order to maintain the locked position on the opening leaf 200.

[0269] FIGS. 90 and 91 illustrate the mounted square spindle 120, inserted in the opening leaf mechanism 201. The mounted square spindle 120 is configured to be adapted to any thickness of follower 202.

[0270] In a fourth step, the first handle 110 is presented at a given angle (here 45°) with respect to the square spindle 120. Then the first handle 110 is inserted on the mounted square spindle as illustrated in FIG. 89. In this position, the first handle 110 slides freely on the square spindle 120 and can be brought to abut on the base plate 156.

[0271] In a fifth step shown in FIGS. 92, 93, the first handle 110 is rotated which makes it possible to mate the relief 112a or 112b of the insert 130 to with the relief 121 of the square spindle 120. This step corresponds to the securing configuration of the first handle 110.

[0272] According to a characteristic of the invention, a latch system (not shown) makes it possible to lock the rotation of the first handle, so that it can be manipulated to control the opening leaf 200 and thus without ever leaving its engaged position. Moreover, it is possible to use a handle assembly 100 intended to be used on an opening leaf of the window type or an opening leaf of the door type. To this end, it is necessary to offset the orientation of the first handle 110 by an angle of 90° at the moment of its insertion on the door.

[0273] As illustrated in FIG. 84, the two complementary reliefs 112a, 112b of the insert make it possible to assemble the same first handle in two opposite directions as required, and as a function of the direction of rotation of the first handle during the fifth step illustrated in FIGS. 92, 93. According to the invention, in the absence of one of the reliefs 112a or 112b, the locking phase of the first handle 110 only operates in one direction, but this does not thereby limit it in use.

[0274] FIGS. 94 to 99 illustrate the principle of two reliefs 112a, 112b of the insert 130. In FIGS. 94 and 95, the relief 121 of the square spindle 120 is engaged with the first complementary relief 112a. In FIGS. 96 and 97, the relief 121 of the square spindle 120 is positioned between the two reliefs 112a, 112b in a space without a relief 112c. In FIGS. 98 and 99, the relief 121 of the square spindle 120 is engaged with the second complementary relief 112b.

[0275] Regardless of the embodiment of the handle assembly 100 according to the invention, said assembly can integrate a handle return system 170 as illustrated in FIGS. 29 to 43. Advantageously, the return system 170 is applied on the first handle 110 of the handle assembly 100.

[0276] In the first embodiment and in the second embodiment of the return system 170, the latter comprises an expansive base plate 171, an expansion cam 172 and a return spring 173.

[0277] The parts common to the two first embodiments will now be described.

[0278] The expansive base plate 171 is in the shape of a disk comprising a front portion turned towards the first handle 110 and a back portion turned towards the second handle 101 and/or the opening leaf 200 in the case of a handle assembly 100 having a single handle. The back face of the base plate comprises a plurality of elastically deformable blades 174 arranged around a central orifice 175. Preferably, the expansive base plate 171 comprises three blades 174 arranged regularly around the orifice 175. The blades 174 each have a curved shape, for example in the shape of a wave one end of which is curved forming a hook like a spear 176. The blades 174 extend over their thickness i.e. over the segment tangential to the central orifice 175. The blades are configured to extend radially from the central orifice 175 when the latter are stressed.

[0279] The expansion cam 172 is in the shape of a ring or a cylinder. The expansion cam 172 comprises a front portion on which a drive spur 177 is positioned, the drive spur 177 being intended to cooperate with the insert 130. More particularly, during the rotation of the first handle 110, the stop spur 139 of the insert 130 abuts against the drive spur 177 so as to allow the driving of the cam. The expansion cam 172 is shaped to interlock in the expansive base plate 171 and more particularly to cooperate with the expansive base plate 171. In addition, the expansion cam 172 comprises a back portion on which a plurality of projections 178 are arranged. Preferentially, the back portion of the cam comprises three projections 178. The projections 178 are regularly distributed and arranged around a central through orifice 179. The projections 178 are in the shape of progressive ramps in one and the same direction of rotation about a longitudinal median axis A-A of the expansion cam 172. The projections 178 are provided at one end with a stop 178a, preferentially rounded, which is shaped to cooperate with the blades 174. During the assembly of the return system 170, the centering orifice 175 of the expansive base plate 171 is substantially concentric with the central orifice 179 of the expansion cam 172. Furthermore, at least the back portion of the expansion cam 172 is integrated between the blades 174 without stressing them.

[0280] The spring 173 of the return system 170 is preferably in the shape of a spiral with at least one coil. The spring 173 comprises a first end 173a shaped to cooperate with the expansive base plate 171. The expansive base plate 171 comprises a recess for receiving said first end 173a of the spring 173 intended to ensure the secure support of the end 173a of the spring with the expansive base plate 171.

[0281] Of course, the spring can have any known shape making it possible to fulfil the same function, such as a tension or compression spring.

[0282] The spring 173 comprises a second end 173b shaped to cooperate with the first handle 110. In the embodiment shown in FIG. 29, the adapter 140 comprises a recess 141 for receiving said end 173b. Other embodiments are possible by arranging the recess for receiving the end 173b of the spring 173 in elements of the handle assembly 100 that are mobile with respect to the expansive base plate, such as for example the insert 130 or the body of the handle 110.

[0283] In order to mount the handle assembly 100 according to the invention equipped with a return system 170 according to any one from the first embodiment and the second embodiment, on an opening leaf 200, the following steps illustrated by FIGS. 21 to 28 are followed.

[0284] In FIGS. 21 and 22 the positioning of the second handle 101 of the handle assembly 100 on the opening leaf 200 is illustrated. As can be seen, the square spindle 120 is already installed on the second handle 101. The second handle 101 is mounted on the opening leaf 200 so that its grip portion is substantially horizontal. Several fastening systems can be used to fix the second handle 101 to the opening leaf, in the example illustrated in FIG. 22, an adhesive arranged on a face of the rose equipping the second handle 101 is used.

[0285] In FIG. 23, the first handle 110 of the handle assembly 100 is presented opposite the orifice of the opening leaf 200 and opposite the square spindle 120 projecting from the opening leaf 200. The grip portion 113 of the first handle 110 is oriented along a substantially vertical axis.

[0286] In FIGS. 24, 32, 33 and 34, the first handle 110 is positioned against the opening leaf 200 by being fitted on the projecting square spindle 120. Preferably, the rose 102 of the first handle 110 comprises an adhesive on one face allowing the positioning of the first handle 110 on the opening leaf 200. As can be seen in FIG. 34, the projections 178 are abutted against the spear-shaped ends 176, said ends being radially withdrawn with respect to the opening leaf aperture 203.

[0287] In FIGS. 25 and 35, the first handle 110 is rotated by a first angle of rotation (approximately 45°). This first rotation makes it possible to bring the stop spur 139 arranged on the insert 130 into contact with the drive spur 177 of the expansion cam 172.

[0288] In FIGS. 26, 36 and 37, the rotation of the first handle 110 is continued by a second angle of rotation (approximately 45°) in the same direction of rotation as in FIG. 25, so that the grip portion 113 is substantially horizontal. In this position, the clamp 142 is locked and the expansion cam 172 is driven so that the latter and in particular the projections 178 press against the spear-shaped ends 176 of the blades 174 which are partially deployed in the aperture 203 of the opening leaf 200, penetrating the opening leaf 200, as illustrated in FIG. 37. Once the spears 176 are partially deployed, the first handle 110 is partially secured to the opening leaf 200 and the return system 170 is ready to be used.

[0289] During the first use of the handle 110, the grip portion 113 is substantially inclined at 45° to the horizontal as illustrated in FIG. 27. In this position, the expansion cam 172 is driven so that the latter and in particular the projections 178 press against the spear-shaped ends 176 of the blades 174 which are fully deployed in the aperture 203 of the opening leaf 200, as illustrated in FIG. 39. Once the spears 176 are fully deployed, the first handle 110 is fully secured to the opening leaf 200.

[0290] During the return of the grip portion 113 to the horizontal position, the cam 178 is not driven and remains fixed in position, maintaining the spears 176 in anchoring position in the aperture 203.

[0291] The first handle 110 is actuated downwards as illustrated in FIGS. 27, 38, 39 i.e. in the same direction of rotation as for the assembly and the deployment of the spears 176. The return system 170 returns the first handle 110 to horizontal position as illustrated in FIG. 28 as illustrated in FIGS. 28, 40 and 41.

[0292] In the first embodiment, the expansive base plate 171 is made in a single piece. In addition, the latter 171 comprises an immobilizing pin 171a positioned on a face opposite the face having blades 174. The immobilizing pin 171a is configured to abut against the drive spur 177 of the expansion cam during the rotation of the first handle 110 as can be seen in FIGS. 38 and 40.

[0293] In the first embodiment, the spring 173 only comprises one coil.

[0294] In the first embodiment, the blades 174 of the expansive base plate 171 are oriented towards the second handle 101.

[0295] In the first embodiment, the solutions implemented aim to make it possible to compensate any possible defects of concentricity between the aperture 203 arranged in the door and the latch mechanism 201 in which the square spindle 120 will be mounted. To this end, the diameter of the cavity 179 is substantially greater than the diameter in which the square spindle 120 lies so as to offer an assembly tolerance. In this first embodiment, the expansive base plate 171 is intended to receive the return spring 173 on an area situated outside the aperture 203. The geometry of the drive pin 177 is provided to allow its actuation by the stop spur 139 in the whole of the permitted tolerance range, which is for example +/−1.6 mm.

[0296] In the second embodiment, the return spring function and a catch mechanically reinforcing the hold of the first handle 110 on the opening leaf 200 is directly integrated in the opening leaf aperture 203.

[0297] In the second embodiment, the expansive base plate 171 is formed of two separate parts free in rotation one with respect to the other, and connected to one another by the spring 173. Thus the expansive base plate 171 comprises an expanding ring 180 and an attachment hub of the spring 181. The expanding ring 180 is positioned around the attachment hub of the spring 181 in assembled configuration.

[0298] In the second embodiment, the blades 174 of the expansive base plate 171 are oriented towards the first handle 110.

[0299] In the second embodiment, the end 173a of the spring 173 cooperates with a portion of the attachment hub of the spring 181 and the end 173b cooperates with the expanding ring 180.

[0300] Of course, the invention is not limited to the embodiments described and shown in the attached figures. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of equivalent techniques, without however exceeding the scope of protection of the invention.

[0301] In particular, other modes of securing the base plate with the opening leaf can be envisaged, in particular by making use of principles of the expansion bolt type (Molly bolt for example). In this case the movement of the handle in rotation about the square spindle would drive expansion by screwing compression.

[0302] Another mode would consist of carrying out direct screwing of the base plate by means of a suitable thread arranged on the outer body of the tubular portion of the base plate entering the aperture 203 in order to secure the base plate with the opening leaf during the movement in rotation for securing the handle to the square spindle.

[0303] Of course, the different characteristics, forms, variants and embodiments of the invention can be combined with one another in various combinations, provided that they are not incompatible or mutually exclusive.
