[0001] The present invention relates to a moving device for moving manoeuvring or closing members of a window or door. More in particular, the present invention relates to a moving device for moving manoeuvring or closing members of a window or door of the type controlled by rotation of the pin ("square pin" or "square") of a control handle.
[0002] In the sector of windows and doors, the use is known of handles applied to the profile that forms the side of the movable panels (leaves), opposite the one at which the articulation hinges of the movable panel itself are fixed and the rotation of which controls, through a relevant moving device, the sliding of one or more vertical rods, also housed in the profile itself.
[0004] The moving device which, in technical jargon, is called a "mechanism" ("macchinetta") supports and contains a rotating element, which is provided with a coupling seat for the coupling in rotation with the pin of the handle (pin which, in technical jargon, is indicated as "handle square" or "square pin" considering its straight quadrangular cross section), and a mechanism that allows the rotational motion of such rotating element to be transformed into the translational motion of one or more sliders that can in turn be coupled with a respective said vertical rod.
[0005] The movement devices ("mechanisms") of the known type are housed inside seats obtained in the profile that forms the side of the frame of the movable leaf of a window or door; this imposes limits on the total dimensions of such moving devices.
[0006] According to the prior art, handles that can be coupled with such moving devices comprise an attachment base or rosette on which the lever, knob or control handle is rotatably mounted, in which the square pin is engaged.
[0007] The attachment base or rosette is fixed to the profile through screws that are engaged in corresponding threaded holes obtained in the case of the moving device ("mechanism"). For that purpose the attachment base or rosette is crossed by a plurality of holes that are superimposed on corresponding holes obtained in the profile itself for the passage through them of fixing screws to the casing of the moving device.
[0008] The attachment base or rosette, further, contains reference members of the different angular positions that the handle assumes in use (open, closed and/or overturned).
[0009] Such attachment bases or rosettes are an additional component of control handles that increase the production costs thereof and that require long and laborious operations both for the assembly to the other components that form the respective handle and for mounting on the profile in coupling with the moving device.
[0011] Within this general aim, an aim of the present invention is to provide a moving device for moving manoeuvring or closing members of a window or door of the type controlled by the rotation of the pin of a control handle that allows handles to be used that have a simpler structure than that of the handles that are applied thereto according to the prior art, in particular handles without attachment bases or rosettes.
[0012] Another aim of the present invention is that of providing a moving device for moving manoeuvring or closing members of a window or door of the type controlled by the rotation of the pin of a control handle that allows the assembly and mounting operations of the related control handle to be simplified.
[0013] Another aim of the present invention is that of providing a moving device for moving manoeuvring or closing members of a window or door of the type controlled by the rotation of the pin of a control handle that allows stable and secure mounting of the handle coupled thereto and precise and secure positioning of the handle itself in its different positions of use.
[0014] Another aim of the present invention is that of providing a moving device for moving manoeuvring or closing members of a window or door of the type controlled by the rotation of the pin of a control handle that is structurally simple, has overall contained dimensions and can also be applied to profiles with a reduced section.
[0015] These aims according to the present invention are achieved by providing a moving device for moving manoeuvring or closing members of a window or door of the type controlled by the rotation of the pin of a control handle as disclosed in claim 1.
[0017] The characteristics and advantages of a moving device for moving manoeuvring or closing members of a window or door of the type controlled by the rotation of the pin of a control handle according to the present invention will be more apparent from the following exemplifying and non-limiting description, with reference to the attached schematic drawings in which:

[0018] With reference to the appended figures, the reference numeral 10 indicates a moving device for moving manoeuvring or closing members of a window or door, of the type controlled by the rotation of the pin of a handle 200.
[0019] The device 10 comprises a supporting and holding body 11 able to be fastened to a movable panel or leaf of a window or door. The supporting and holding body 11 is composed of a casing 12 and a cover 13 that are fastened to each other for example with a shape coupling, interlocking coupling or with screws.
[0020] The supporting and holding body 11 is provided with through holes 14 that are obtained in the casing 12 and in which screws 15 can be inserted, through which the supporting and holding body 11 is fastened to the movable panel of a window or door.
[0021] In particular, the supporting and holding body 11 is fastened to a profile 100 that defines a side of the movable panel.
[0022] The supporting and holding body 11 is fastened at a channel 101 of the profile 100 in which manoeuvring or closing members are housed of the type for example of manoeuvring or closing rods, which are not depicted as they are known to a person skilled in the art.
[0023] The supporting and holding body 11 can be at least partially inserted in the channel 101 in which the manoeuvring or closing members are housed. More generally, the supporting and holding body 11 can be at least partially inserted in a hollow seat obtained inside the profile 100 and accessible from the outer flank or outer rib thereof. As will appear more clearly below, the supporting and holding body 11 can be fastened to the profile 100 to the rear of the wall 102 thereof, which wall extends parallel to the plane of the window or door. The supporting and holding body 11 can be fastened to the profile 100 at the rear face of the wall 102, i.e. of the face of the wall 102 opposite the front one from which the handle projects.
[0024] A rotating element 16 is housed in the supporting and holding body 11 rotatably around an axis of rotation R which, when the device 10 is mounted on the movable panel of a window or door, is orthogonal to the plane defined by the panel itself.
[0026] The rotating element 16 is activated in rotation around the axis of rotation R by a pin 201 of a control handle 200.
[0027] The handle 200 can have any shape such as, for example, that of a lever or a knob. The pin 201 may be joined to the handle 200 rigidly, completely (i.e. fixed in rotation and translation) and removably in any way, also different from the one represented in the appended figures and that is not part of the present invention and, therefore, not described in detail.
[0028] The casing 12 and the cover 13 are crossed by the respective through holes 120 and 130 which are coaxial to the axis of rotation R for the passage of the pin 201 through them.
[0029] The pin 201 generally has a polygonal orthogonal, preferably straight quadrangular, section and, even more preferably, square; for this reason the pin 201 is known in technical jargon as "square pin".
[0030] The pin 201 generally has a constant orthogonal section along its entire axial extension, apart from any grooves or notches necessary for example for joining it to the handle 200 and/or end portions that may be tapered.
[0031] The pin 201 is joined in rotation to the rotating element 16 by means of a prismatic coupling.
[0032] For that purpose, the rotating element 16 is provided with a hollow seat 18 that is coaxial to the axis of rotation R and that comprises a first axial section 18a that is shaped so as to be coupled with a prismatic coupling to a corresponding first axial section of the pin 201.
[0033] The first axial section 18a of the hollow seat 18 therefore has a prismatic (hollow) orthogonal section that matches the prismatic (solid) orthogonal section of the corresponding first axial section of the pin 201, so as to provide a coupling such as to make the rotating element 16 integral/fixed in rotation with the pin 201.
[0034] In the event that the pin 201 has a straight quadrangular orthogonal section and, in particular, square, the first axial section 18a of the hollow seat 18 has a straight quadrangular orthogonal section and, in particular, square, imitating that of the pin 201.
[0035] The rotation imposed on the rotating element 16 through the handle 200 and related pin 201 is transformed into translational motion of at least one slider 19 along the two opposite directions of a same straight line D through a transformation mechanism of the type known per se.
[0036] Such transformation mechanism may, for example, comprise a toothing 20 that is obtained along at least one section of the outer side surface of the rotating element 16 and that is engaged with a corresponding toothing of a rack 21.
[0037] The rack 21 is arranged parallel to the straight line D and is guided in translation along the back of the supporting and holding body 11; when the device 10 is mounted on the profile 100, the straight line D extends parallel to the longitudinal extension of the channel 101.
[0038] The slider 19 is provided with an attachment element 22 for joining with a manoeuvring or closing member, such as a rod.
[0039] In the embodiment shown in the appended figures, the device 10 activates only one rack 21 in translation. It is specified, however, that the rotating element 16 could activate in rotation, directly or indirectly, a second parallel rack, diametrically opposite and facing the rack 21.
[0040] Furthermore, alternative embodiments of the transformation mechanism of the rotational motion of the rotating element 16 into the translational motion of the slider 19 are not excluded.
[0041] According to a first aspect of the present invention, the pin 201 is locked in the rotating element 16 not only in rotation, but also axially so as to prevent relative axial sliding of one with respect to the other, in particular in the mutual disconnection or detachment direction. The axial locking of the pin 201 in the rotating element 16 allows the handle 200 to be fastened axially to the profile 100 even without the aid of further components such as, for example, an attachment base (in jargon "rosette") on which, according to the prior art, the handle 200 is mounted rotatably and that is fastened to the profile 100 by means of respective screws that are engaged in threaded holes obtained in the casing of the device 10.
[0042] The pin 201 is axially locked in the rotating element 16 removably, so as to allow the disassembly of the handle 200 if necessary.
[0043] The axial locking of the pin 201 is provided through locking means 22 that are arranged in the hollow seat 18 of the rotating element 16.
[0044] More in detail, the hollow seat 18 comprises a second axial section 18b which is distinct from the first axial section 18a and in which the locking means 22 are arranged for the removable locking of the axial sliding of the pin 201 along the axis of rotation R.
[0045] The locking means 22 are configured to allow, during the mounting step of the handle 200 on the movable panel, the axial sliding of the pin 201 into the hollow seat 18 in the direction of insertion of one into the other and to prevent the relative axial sliding of one relative to the other in the opposite direction, when the handle 200 is in the configuration mounted on the movable panel.
[0046] In the appended figures, the arrow A indicates the direction of insertion of the pin 201 into the rotating element 16.
[0047] The second axial section 18b of the hollow seat 18 follows, in the direction of insertion A, the first axial section 18a.
[0048] The locking means 22 comprise at least one plate 23 which is crossed by an opening 24 that has a central axis C and at least two perimeter portions mutually opposed to each other and substantially matching with corresponding portions mutually opposed to each other of the outer side surface of a corresponding second axial section of the pin 201.
[0050] The plate 23 is housed in the second axial section 18b of the hollow seat 18 in a movable way between an inclined position, in which its opening 24 is arranged with the respective central axis C oblique with respect to the axis of rotation R, and a straight position, wherein the opening 24 thereof is arranged with the respective central axis C thereof substantially coaxial with the axis of rotation R.
[0051] As can be noted from figure 8, the central axis C of the opening 24 of the plate 23 and the axis of rotation R are incident at a non null angle.
[0052] The plate 23 is housed in the second axial section 18b of the hollow seat 18 with the possibility to oscillate with respect to an oscillation axis orthogonal to the axis of rotation R and different from the central axis C.
[0053] When the plate 23 is in its straight position, the pin 201, i.e. the second axial section thereof, can slide axially in the opening 24.
[0054] When the plate 23 is in its inclined position, the pin 201, i.e. the second axial section thereof, is locked axially into the opening 24 following the interference and friction that are generated between the at least two opposite perimeter portions of the opening 24 and the corresponding portions of the outer side surface of the second axial section of the pin 201 matching them.
[0055] In practice, when the plate 23 is in the inclined position, considering the projection of its opening 24 on an orthogonal plane to the axis of rotation R, the distance between its two opposite perimeter portions matching with corresponding portions of the outer side surface of the second axial section of the pin 201 is less than the distance between the latter two, which are therefore locked by the first ones by interference and friction.
[0056] Advantageously, the plate 23 is made of elastically yielding material and can be comprised of a leaf spring or a strip spring.
[0057] With reference to the embodiment shown in the appended figures, the opening 24 of the plate 23 is shaped like a straight quadrangular prism, in particular with a square base, at least two opposite faces 24', 24'' of which substantially match with corresponding opposite faces of the second axial section of the pin 201, said second axial section of the pin 201 also being shaped like a straight quadrangular prism, in particular with a square base.
[0058] Advantageously, the opening 24 has a shape that imitates/matches that of the orthogonal section of the corresponding second axial section of the pin 201 with which it is engaged.
[0059] It is specified that in the present description the distinction between the first and second axial section of the pin 201 is made in order to distinguish different longitudinal portions of the pin 201 which, with particular reference to the embodiment shown in the appended figures, are in continuous succession all having the same cross section (i.e. square).
[0060] In that case, the plate 23 is movable between the inclined position and the straight position thereof for oscillation with respect to an axis of oscillation parallel to the two opposite faces 24', 24'' thereof and orthogonal to the axis of rotation R.
[0062] The second axial section 18b of the hollow seat 18 has a greater cross section than that of the first axial section 18a thereof.
[0063] The second axial section 18b of the hollow seat 18 is obtained downstream, with respect to the insertion direction A of the pin 201, with respect to the first axial section 18a of the hollow seat 18.
[0065] The second axial section 18b ends in one of the two axially opposite ends of the hollow seat 18.
[0066] The transition surface 25 or shoulder between the first axial section 18a and the second axial section 18b is comprised of a frame that lies on an inclined plane with respect to the central axis of the hollow seat 18, which axis coincides with the axis of rotation R.
[0067] Such transition surface 25 forms a support surface for the plate 23 in the inclined position.
[0068] The locking means 22 then comprise at least one first elastic thrust element 26 which is arranged in the hollow seat 18 to exert on the plate 23 a thrust in the retention direction thereof in the inclined locking position of the pin 201.
[0069] The at least one first elastic thrust element 26 is comprised of a distinct body from the plate 23; i.e. it does not form a single body with the plate 23.
[0070] The first elastic thrust element 26 exerts on the plate 23 a thrust in the retention direction thereof resting on the inclined plane defined by the transition surface 25.
[0071] Such first elastic thrust element 26 is arranged in the second axial section 18b of the hollow seat 18 and is interposed between the plate 23 and a fixed abutment element, also obtained or housed in the second axial section 18b of the hollow seat 18.
[0072] Such fixed abutment element is comprised of a first cover 27 that is removably fixed to the rotating element 16.
[0073] The first cover 27 is fixed, for example with a shape coupling or an interlocking coupling, to the second axial section 18b of the hollow seat 18, at the open end thereof opposite the one that is connected to the first axial section 18a of the hollow seat 18 itself. This end defines one of the two axially opposite ends of the hollow seat 18; it is open and leads directly to the outside.
[0074] The first cover 27 is crossed by a passage opening 28 for the passage of the pin 201 through it.
[0075] Advantageously, the first elastic thrust element 26 is housed in the second axial section 18b of the hollow seat 18 and is interposed between the plate 23 and the first cover 27.
[0076] In a preferred embodiment, the first elastic thrust element 26 is integrally formed with the first cover 27; in that case, the first elastic thrust element 26 is for example comprised of an elastically yielding tab that projects from the face of the first cover 27 turned towards the inside of the hollow seat 18.
[0077] The first cover 27 and the first elastic thrust element 26 are integrally formed (integral to each other) in a single body.
[0078] In a preferred embodiment, the first cover 27 and, with it, possibly also the first elastic thrust element 26 are made of a material such as to guarantee a thrust and friction effect on the plate 23 so as to retain it in its inclined position. The first cover 27 and with it the first elastic thrust element 26 allow any coupling clearances that can be generated in use to be compensated, keeping the plate 23 in the inclined position and guaranteeing stable axial locking of the pin 201 in the rotating element 16 and, therefore, of the handle 200 with respect to the device 10 fixed to the profile 100.
[0079] The first cover 27 and with it the first elastic thrust element 26 allow to compensate for any coupling clearances that can be generated in use following vibrations to which the pin 201 is subject, thus having a damping and absorbent effect on such vibrations.
[0080] To allow the dismounting of the pin 201 from the rotating element 16 and, therefore, the dismounting of the handle 200 from the device 10, a manoeuvring tool 300 can be used, e.g. a key, that can be inserted in the rotating element 16 for being able to act on the plate 23 and bring it into its straight position.
[0081] For that purpose, the rotating element 16 comprises a radial through hole 29 that is defined at the second axial section 18b of the hollow seat 18 and that is accessible from the outside of the device 10 for the insertion of the manoeuvring tool 300 through it.
[0082] The radial through hole 29 is obtained at the second axial section 18b of the hollow seat 18 in proximity to the transition surface 25 that separates it from the first axial stretch 18a of the hollow seat 18 itself. The transition surface 25 itself comprises a recess 30 that is obtained in proximity to the outlet of the radial through hole 29 for promoting the entry and manoeuvres of the manoeuvring tool 300 on the plate 23.
[0083] In practice, the manoeuvring tool 300 is interposed between the transition surface 25 and the plate 23. The manoeuvring tool 300 thus acts on the face of the plate 23 opposite the one turned towards the first cover 27. Through the manoeuvring tool 300 it is possible to move the plate 23, in contrast to the thrust action exerted thereon by a possible first thrust element 26, from the inclined position thereof, in which it locks the axial sliding of the pin 201, to the straight position thereof, in which it allows the axial sliding of the pin 201.
[0084] In order to be able to access the radial through hole 29 of the rotating element 16, the device 10 is provided with a corresponding access hole 31.
[0085] The access hole 31 is obtained in the body of the rack 21 which, when the device 10 is fixed to the profile 100, is accessible from the outside.
[0086] It is to be noted that in the body of the rack 21 further through holes 40 are also provided that allow access to the head of the screws 15 inserted in the holes 14 of the casing 12.
[0087] Furthermore, advantageously, the manoeuvring tool 300 is supported by a drawer element 301 mounted on the supporting and holding body 11.
[0088] The hollow seat 18 of the rotating element 16 is in practice comprised of an axial through hole that crosses the rotating element 16 itself and that has opposite open ends.
[0089] Along the axial extension of the hollow seat 18 there is the following succession: the second axial section 18b, the first axial section 18a and, preferably, a third axial section 18c thereof. It is specified that the distinction between the first, second and third axial section of the hollow seat is made for the sole purpose of greater descriptive clarity.
[0090] The first axial section 18a, the one that defines the prismatic coupling with the pin 201, is interposed between the second axial section 18b and the third axial section 18c, both of which have a greater cross section than the cross section of the first axial section 18a and each terminate in one of the two axially opposite ends of the hollow seat 18.
[0091] The rotating element 16 further comprises a second cover 32 that is removably fixed in the third axial section 18c of the hollow seat 18. The second cover 32 is fixed, for example with a shape coupling or an interlocking coupling, at the end of the third axial section 18c of the hollow seat 18 open and opposite the transition surface 33 between the third axial section 18c and the first axial section 18a of the hollow seat 18.
[0092] The second cover 32 has a structure and conformation that are completely analogous to those of the first cover 27.
[0093] The second cover 32 is crossed by a passage opening 34 for the passage of the pin 201 through it.
[0094] A second elastic thrust element 35 is interposed between the second cover 32 and an abutment surface 350 obtained in the third axial section 18c of the hollow seat 18. Such abutment surface 350 is defined by a hollow of the transition surface 33 between the third axial section 18c and the first axial section 18a of the hollow seat 18.
[0095] Advantageously, the second elastic thrust element 35 is integrally formed with the second cover 32. In particular, it is comprised of an elastic tab that extends from the face of the second cover 32 turned towards the inside of the hollow seat 18 and that is housed in the hollow of the transition surface 33.
[0096] The second cover 32 and with it the possible second thrust element 35 allow to compensate for any clearances that could be generated in use, guaranteeing stable fastening of the pin 201 in the rotating element 16.
[0097] The second cover 32 and with it the second elastic thrust element 35 allow to compensate for any coupling clearances that can be generated in use following vibrations to which the pin 201 is subject thus having a damping and absorbent effect on such vibrations.
[0098] The second cover 32 and with it the second elastic thrust element 35 cooperates with the first cover 27 and the related first elastic thrust element 26 for keeping the plate 23 in the inclined position and thus guaranteeing stable axial locking of the pin 201 in the rotating element 16 and, therefore, of the handle 200 with respect to the device 10 fixed to the profile 100. It is noted that the first elastic thrust element 26 and the second elastic thrust element 35 are arranged opposed to each other and staggered so that the thrust actions exerted thereby cooperate to retain the plate 23 in the inclined position. Thus for example, the first elastic thrust element 26 is arranged to exert its thrust action on the edge of the plate 23 that defines the edge 24'', while the second elastic thrust element 35 is arranged to exert its thrust action on the edge of the plate 23 that defines the opposite edge 24'.
[0099] As can be noted from the appended figures, each of the two tabs forming the first elastic thrust element 26 and the second elastic thrust element 35, respectively, has an end constrained to the face of the first cover 27 and of the second cover 32, respectively, which, in the mounting configuration, is turned towards the inside of the hollow seat 18 and the opposite end free.
[0100] Each of such two tabs, in the rest configuration, extends along an inclined direction with respect to the face of the first cover 27 and of the second cover 32, respectively, to which it is constrained.
[0101] In the mounting configuration, each of the two tabs is crushed and bent towards the face of the first cover 27 and of the second cover 32 to which it is constrained, respectively.
[0102] According to a further aspect of the present invention, the device 10 further comprises stopping means 36 for removably stopping the rotating element 16 in at least two different angular positions corresponding to at least two different angular positions of the handle 200.
[0103] Such stopping means 36 act as a reference or positioning of the handle 200 in at least two different angular positions thereof, typically at 90° from each other and corresponding to the closed position and to the open position, or in three different angular positions thereof, typically at 90° from each other and corresponding to the closed position, to the open position and to the overturned position.
[0104] Such stopping means 36 comprise a plurality of depressions 360 that are obtained in the rotating element 16 and that cooperate with at least one pair of projections 361 that are housed in the supporting and holding body 11 in an elastically yielding manner between an engaged position and a disengaged position with the depressions 360, even if the opposite configuration is not excluded.
[0105] The depressions 360 are obtained in the outer side surface of the rotating element 16; in particular, they are obtained along an angular groove 37 or along a cylindrical surface of the outer side surface of the rotating element 16.
[0106] In the embodiment shown in the appended figures, in which the rotating element 16 is in practice comprised of a pinion, the annular groove 37 interrupts the width of the toothing 20 of the pinion itself in a substantially central position. The annular groove 37 extends in a concave surface 370 that interrupts the toothing 20 to allow the sliding of the projections 361 along it.
[0107] One of the depressions 360 is coaxial to the radial through hole 29; another three depressions 360 are arranged at 90° from each other along the annular groove 37.
[0108] The projections 361 are conformed so as to engage in the depressions 360 and to roll or slide along the annular groove 37.
[0109] The projections 361 have a surface that imitates or matches that of the depressions 360 and such as to slide or roll along the annular groove 37.
[0111] The projections 361 are retained in engagement with the depressions 360 by the elastic action exerted thereon by elastic thrust members 38, which are elastically yielding at least along a radial direction with respect to the axis of rotation R and that are constrained to the supporting and holding body 11.
[0112] Such elastic thrust members 38 can be formed integrally with the projections 361 themselves or be constituted of bodies distinct from the projections 361 and arranged to act thereon.
[0113] The elastic thrust members 38 are housed in corresponding housing seats 39 that are obtained in the casing 12 in radial positions with respect to the axis of rotation R. The housing seats 39 have an opening obtained at the crib 17 and through which the corresponding projection 361 protrudes.
[0114] In particular, two projections 361 are provided with respective elastic thrust members 38 arranged at corresponding housing seats 39 diametrically opposing each other with respect to the axis of rotation R.
[0115] The elastic thrust members 38, for example, can be comprised of a variously shaped leaf spring.
[0116] Figures 15 to 17 and 15A to 17A show different possible embodiments of the projections 361 and of the respective elastic thrust elements 38 (in such figures for simplicity purposes only one projection 361 is shown with the respective elastic thrust members 38).
[0117] The operation of the device 10 according to the present invention is immediately comprehensible to a person skilled in the art in light of the appended figures and the description provided above.
[0118] In short, the device 10 is fixed to a profile 100 that defines, alone or coupled with other profiles, a side of the movable panel of a window or door.
[0119] The profile 100 comprises a channel 101 in which members for manoeuvring or closing the window or door are housed, which are activated by the device 10. The profile 100 further comprises a wall 102 that is substantially parallel to the plane of the movable panel and on which the control handle 200 of the device 10 is fixed.
[0120] The wall 102 is crossed by at least one through hole at which the handle 200 is mounted; the pin 201 of the handle crosses such through hole for engaging in the rotating element 16 of the device 10.
[0121] The wall 102 has a front face at which the handle is mounted and from which the handle 200 projects and a rear face opposite the front face. The supporting and holding body 11 is at least partially housed or built into the channel 101 to the rear of the wall 102. More generally, the supporting and holding body 11 is at least partially housed or built in a hollow seat formed inside the profile and accessible from the outer flank or outer rib of the profile, the outer flank or outer rib of the profile meaning the one defined by the side wall 103 of the profile that extends in a substantially orthogonal direction to the wall 102.
[0122] Therefore, the device 10 is mounted on the flank of the profile 100 at the channel 101 so that the axis of rotation R (i.e. the central axis of the rotating element 16) is coaxial with the through hole obtained in the wall 102 of the profile and, therefore, orthogonal to the plane of the movable panel.
[0124] It is to be noted that, considering the device 10 mounted on the profile 100, starting from the wall 102 of the profile, there is the following succession: the third axial section 18c, the first axial section 18a and the second axial section 18b of the hollow seat 18 of the rotating element 16.
[0125] After the device 10 has been fastened to the profile 100, the pin 201 is inserted by axial sliding into the hollow seat 18 of the rotating element 16.
[0126] During such sliding, the thrust action exerted by the pin 201 is sufficient to move the plate 23 in the straight position in contrast to the action of the first elastic element 26, so as to allow the insertion of the corresponding axial section of the pin 201 (i.e. the second axial section of the pin 201) through the opening 24 of the plate 23 itself.
[0127] After insertion, the plate 23, also thanks to the thrust action exerted thereon by the first elastic thrust element 26, is brought back into its inclined position in which, following the interference and friction that are generated between its opposite faces 24' and 24'' with the corresponding opposite faces of the pin 201, it locks the axial sliding of the pin 201 in the disconnection and detachment direction from the device 10 and from the profile 100.
[0128] The pin 201 is thus constrained completely to the rotating element 16: the axial sliding of the pin 201 with respect to the rotating element 16 is locked by the locking means 22, while the relative rotation of the pin 201 with respect to the rotating element 201 is prevented by the prismatic coupling between the first axial section 18a of the hollow seat 18 and the corresponding axial section (first axial section) of the pin 201.
[0129] In conditions of use, the axial locking of the pin 201 is guaranteed by the presence of the first elastic element 26 that exerts on the plate 23 a thrust in the retaining direction of the plate 23 in its inclined position resting on the inclined plane defined by the transition surface 25.
[0130] The rotation imposed on the pin 201 by the handle 200 is transmitted to the rotating element 16 which, in turn, moves the rack 21 and the manoeuvring or closing members connected to the slider 19.
[0131] It is specified that the "rotational motion" of the rotating element 16 takes place in both rotation directions and is limited to an angle less than 360° and, in general, less than 90°.
[0132] The position of the pin 201 and, therefore, of the handle 200 is indicated and identified by the stopping or positioning means 36.
[0133] Should it be necessary to dismount the handle 200 from the profile 100 it is sufficient to insert the manoeuvring tool 300 through the through hole 31 obtained in the body of the rack 21 and the radial through hole 29 obtained in the rotating element 16 for pushing the plate 23 into its straight position in contrast to the action exerted thereon by the first elastic thrust element 26 and disconnect the pin 201 from the hollow seat 18.
[0134] In the appended figures, the movable panel of the window or door, the manoeuvring or closing members and the respective connection rods with the sliders 19 are not shown as they are of the type known to a person skilled in the art. Likewise, the profile 100 is not part of the present invention and the embodiments thereof represented in the appended figures are only provided by way of non-limiting example. Thus, also the fastening of the pin 201 to the handle 200 is not part of the present invention and can be realised in any way, also different from the one depicted.
[0135] The arrangement of the locking means 22 for the axial locking of the pin 201 in the device 10 and, in particular, in the rotating element 16 thereof allows to avoid the use of specific attachment bases or rosettes of the handles which, according to the prior art, are usually used for fastening the handle to the profile and/or to the casing of the device 10 with the use of relevant screws.
[0136] The arrangement of the stopping means 36 for the removable stopping of the pin 201 in its possible angular positions corresponding to the positions of use of the handle 200 (open, closed and/or overturned) in the device 10 and, in particular, in the rotating element 16 thereof allows to avoid the use of specific attachment bases or rosettes of the handle in which, according to the prior art, corresponding stopping or reference means of the positions of use of the handle are usually housed.
[0137] The object of the present invention therefore has the advantage of allowing the direct mounting of the handle 200 on the profile 100 without the aid of attachment bases or attachment rosettes and, consequently, without the need to make any holes on the profile 100 for the set screws of the attachment bases or rosettes. The only hole that must be made on the profile 100, or better on the wall 102 thereof, is the one for the passage of the pin 201.
[0138] Obviously, this does not exclude the possibility of using the device 10 also with handles provided with attachment bases or rosettes.
[0139] The moving device according to the present invention guarantees, in any case, stable and secure mounting of the pin 201 - and of the handle 200 fastened thereto - on the profile 100 preventing axial disconnection in the detachment direction of the profile itself.
[0140] The moving device according to the present invention further guarantees the positioning of the handle in its possible opening, closing and/or overturning positions of use.
[0141] The moving device according to the present invention also has reduced dimensions and can also be used on profiles with reduced sections.
[0142] It is specified that the arrangement of the stopping means 36 for the removable stopping of the pin 201 in its possible angular positions corresponding to the positions of use of the handle 200 (open, closed and/or overturned) in the device 10 and, in particular, in the rotating element 16 thereof can also be adopted in moving devices in which the locking of the axial sliding of the pin, i.e. of the handle fastened thereto, is realised with different means from the locking means 22 as described above and not necessarily arranged inside the moving device itself. The arrangement of the stopping means 36 for the removable stopping of the pin 201 in its possible angular positions corresponding to the positions of use of the handle 200 (open, closed and/or overturned) in the device 10 and, in particular, in the rotating element 16 thereof can be adopted separately and independently from the locking means 22 for the axial locking of the pin 201 as described above.

In practice, the materials used, as well as their dimensions, can be of any type according to the technical requirements.
