Description

The present invention refers to a handle, in particular of the cremone bolt type, applicable onto the frame of a moveable wing of a window or door.
In the field of closures for door or window moveable wings, the so-called cremone bolt-type handles are known.
Generally, a cremone bolt handle comprises a box-shaped body, inside which a rotor is mounted that rotates about a rotation axis orthogonal to the plane of the moveable wing and that can be manoeuvred from the outside through a gripping element or lever.
Inside the box-shaped body, a mechanism is housed for transforming the rotary motion of the rotor into sliding motion of one or two sliders along the opposite senses of a direction parallel to the longitudinal development of the box-shaped body. Each of the two sliders is provided with a respective tab, which in the jargon of the field, is known as "fin" or "strip", onto which the end of a respective rod for manoeuvring or closing the moveable wing can be fixed, rod which is slidably guided along the section that forms the frame and on which the handle is mounted.
The mounting of such cremone bolt handles of the known type occurs through self-threading screws or with the help of opposing counter-plates.
In both cases, in the section on which the handle is to be mounted, not only it is necessary to obtain the slot or slots required for the insertion and the sliding of the "fins" or "strips" and the fixing thereof to the manoeuvring of closing rods, but also the holes for the engagement of the fixing screws or counter-plates. The operations complicate the mounting of the cremone bolt handles of the known type and require particularly skilled operators.
In addition, the anchoring of the box-shaped body becomes unstable over time and due to traction and sheer stresses to which the fixing screws are subjected.
Alternatively to the screws or counter-plates, it is known to use clamping brackets as described in Italian patent n° 1334855 .
According to the teaching of the Italian patent n° 1334855 , the box-shaped body of the handle is fixed to the section which defines the upright of the frame of a moveable wing through a pair of clamping brackets, each of which comprises a plate at the opposite longitudinal ends of which a respective threaded hole is obtained where a respective screw is engaged.
In one of such two threaded holes, a "manoeuvring" screw is engaged, the stem of which is grasped by the operator to manipulate the plate in order to insert and position it into the section on which the handle is to be mounted. In particular, an operator, by grasping such "manoeuvring" screw, inserts the relative plate through the slot obtained in the wall of the section on which the box-shaped body rests and positions it below such wall.
The other of such two holes is obtained in a cylindrical bell that is adapted to be inserted, still by the operator, into corresponding through-holes that are obtained in the wall of the section and into the box-shaped body of the handle and that are superimposed and aligned with respect to each other.
A second screw is then inserted and screwed in the threaded hole obtained in the cylindrical bell so as to clamp the plate against the wall of the section and fix the box-shaped body of the handle to the section itself. During this clamping step, the operator has to hold the plate in position through the "manoeuvre" screw.
Once the clamping has been executed, the "manoeuvre" screw is screwed on the plate with the sole aim of reducing its length that projects from the box-shaped body and that has been used for the manipulating and mounting operations.
However, also this solution has some drawbacks.
Firstly, the clamping of the clamping brackets as described above requires making - on the section - not only the slot for inserting the "fins" or "strips", but also holes for the passage of the cylindrical bells and of the respective clamping screws.
Secondly, the mounting of the handle is particularly complex and laborious; in fact, the operator has to insert one plate at a time, to arrange it in position centring the cylindrical bell, to clamp the clamping screw and the "manoeuvre" screw.
Clamping systems are also known as described in FR2877979 and which comprise a pair of clamping brackets that are arranged at the opposite longitudinal ends of the handle box-shaped body; each clamping bracket is L-shaped and in each of them a unique clamping screw is engaged, the screwing of which allows the respective bracket to be clamped against the internal surface of the section wall that is thus clamped between the bracket and the handle box-shaped body.
In addition, in cremone bolt handles of the known type, the "fins" or "strips" comprise each a tab that is fixed to the respective slider and onto which an attachment plate is slidingly mounted that is provided with a hole wherein a fixing member (screw or pin) is engaged for fixing the end of a respective manoeuvre or closing rod. A fastening element for adapting the position of closing rods is described in EP 2 017 415 A2 .
The sliding of the attachment plate allows adjusting the height of the "fin" or "strip" as a function of the depth of the section on which the handle is to be mounted.
In the "fins" or "strips" of the known type, the attachment plate is however free to slide along the respective tab; thus the operator has to find its correct position during the mounting of the handle.
A general object of the present invention is to overcome the drawbacks of the prior art.
Within this general object, a particular object of the present invention is to obtain a handle, in particular of the cremone bolt type, applicable onto the frame of a moveable wing of a window or door, allowing determining the height of the "fins" or "strips" as a function of the depth of the section forming the frame in a simple and accurate manner.
A further object of the present invention is to make a handle, in particular of the cremone bolt type, applicable onto the frame of a moveable wing of a window or door, the mounting of which does not require particular operations on the frame or sections forming it and, in particular, does not require obtaining therein further slots or holes with respect to those required for the passage and sliding of the relative "fins" or "strips".
A further object of the present invention is to make a handle, in particular of the cremone bolt type applicable onto the frame of a moveable wing of a window or door, the mounting of which is particularly simple and quick, as well as particularly stable and safe over time.
Another object of the present invention is to make a handle, in particular of the cremone bolt type applicable onto the frame of a moveable wing of a window or door that is particularly simple, functional and cost saving.
These objects according to the present invention are attained by making a handle, in particular of the cremone bolt type applicable onto the frame of a moveable wing of a window or door, as outlined in claim 1.
Further characteristics are provided in the dependent claims.

A handle 10 according to the present invention is shown with reference to the figures.
The handle 10 is of the so-called "cremone" bolt type and is applicable onto the frame of a moveable wing of a window or door.
The attached figures solely schematically show a portion of a possible section 100 forming the side or upright of the frame and on which the handle 10 is to be mounted; the frame and the moveable wing are not further shown and described, being of the type known to a person skilled in the art.
The section 100 is, in particular, a metal section.
The section 100 may be shaped differently from the shape represented in the attached figures; in any case, it is provided with an axial channel 101 delimited by at least two walls orthogonal to each other, respectively a first wall 102 and a second wall 103. The first wall 102 defines the support surface whereon the handle 10 rests and it is provided with a first slot 104.
The second wall 103 is provided with a channel 105 for guiding manoeuvre or closing rods 106 and is crossed by one or two second slots 107 defined at the first slot 104.
The handle 10 comprises a box-shaped body 11 that has a substantially longitudinal development.
The box-shaped body 11 has a resting face 12 for resting on the frame and, in particular, onto the external surface of the first wall 102 and a face 13 opposite the resting face 12. The resting face 12 and the opposite face 13 are substantially flat and parallel to each other.
A handgrip 14 projects from the face 13 and is fixed to a rotor 15 that is housed in the box-shaped body 11 in a rotatable manner about a rotation axis R orthogonal to the resting face 12.
Thus, the handgrip 14 allows manoeuvring the rotor 15, serving as a handle or lever.
It is observed that the rotor 15 can rotate in both rotation senses and also for limited defined rotation angle generally less than or equal to 180° and generally equal to 90°.
Fixed or obtained in a unique piece on the rotor 15 is an element 17 of a mechanism 18 for transforming the rotary motion of the rotor 15 into a translation motion of at least one slider 19, which can be coupled to a respective rod 106.
In the embodiment represented in the attached figures, the handgrip 14 is fixed to the rotor 15 through a screw 45, a joint or any other equivalent fixing system.
Still with reference to the embodiment represented in the attached figures, the mechanism 18 is of the rack and pinion type and a pair of sliders 19 is provided slidable in opposite senses along a direction parallel to the longitudinal development of the box-shaped body 11. However, alternative embodiments of the mechanism 18 are not excluded.
More in detail, the element 17 is constituted by a sprocket which meshes with a pair of racks 20 parallel and facing each other and only one of which is partly visible in figure 4.
The two racks 20 are housed in a corresponding rectilinear guide that is defined between a guide body 21 inserted in the box-shaped body 11, the box-shaped body 11 itself and a cover 22 removably mounted on the box-shaped body 11 at the resting face 12 thereof. The guide body 21 is advantageously made of low friction plastic material and has a substantially T-shaped cross section interrupted in the central position by a housing 23 in which the element 17 (i.e. the sprocket) is positioned.
A respective slider 19 is fixed to each of the two racks 20.
It is observed that the mechanism 18 in its entirety is housed and contained in the box-shaped body 11.
In the embodiment represented in the attached figures, the rotor 15 and the element 17 are obtained in a single piece and they form a unique body; however, alternative embodiments in which the rotor 15 and the element 17 may, for example, be obtained as separate bodies and then assembled to form a unique body cannot be excluded.
Each of the two sliders 19 is provided with a tab 24 that extends in the direction substantially parallel to the rotation axis R on a plane parallel to the longitudinal plane of the box-shaped body 11 and which projects from the resting face 12 of the box-shaped body 11 to insert into the first slot 104.
According to the present invention, an attachment plate 25 is guided on each tab 24, slidably along a direction parallel to the rotation axis R, onto which attachment plate the end of a respective rod 106 can be fixed.
The tab 24 alone or the assembly of each tab 24 and the respective attachment plate 25 in its entirety is referred to as "fin" or "strip" in the field.
In addition, the handle 10 is provided with a covering plate 26 for covering the face 13 of the box-shaped body 11 opposite the resting face 12.
The covering plate 26, in cooperation with the box-shaped body 11, defines the external shape of the handle 10.
The covering plate 26 is mounted on the box-shaped body 11 in a rotatable manner around the rotation axis R through a snap or spring mechanism of the known type.
The covering plate 26 is moveable between a first position, in which it is superimposed and aligned to the box-shaped body 11 to entirely cover the face 13 thereof, and a second position, in which it is rotated by about 90° to partially uncover the face 13 so as to allow access to the connection and fixing members of the handle 10 to the section 100 and as described hereinafter, by an operator.
In fact, according to a distinctive characteristic of the present invention, the handle 10 comprises a pair of clamping brackets 27 for clamping the box-shaped body 11 to the section 100.
The clamping brackets 27 are mounted close to the opposite longitudinal ends of the box-shaped body 11 and each of them comprises a first portion 28 and a second portion 29 connected to each other substantially at 90°.
The first portion 28 of each of the two clamping brackets 27 is mounted inside the box-shaped body 11 to which it is coupled with a coupling adapted to prevent the rotation of the respective clamping bracket 27 about axes parallel to the rotation axis R and to allow both the sliding of the respective clamping bracket 27 for a defined stroke along a direction parallel to the rotation axis R and the oscillation of the respective clamping bracket 27 on a longitudinal plane of the box-shaped body 11 and orthogonal to the resting face 12 for a defined oscillation angle.
As clearer from the description that follows, the sliding stroke of the clamping brackets 27 along a direction parallel to the rotation axis R allows fastening clamping brackets 27 themselves against the first wall 102 of the section 100 which delimits the first slot 104 so as to anchor the box-shaped body 11 thereto.
Instead, the oscillation of the clamping brackets 27 allows inclining while approaching them towards the centre of the box-shaped body 11 so as to allow the insertion into the first slot 104 without interference with the section 100.
The second portion 29 of each clamping bracket 27 projects from the resting face 12 of the box-shaped body 11 to insert into the first slot 104 obtained in the section 100 and to rest onto the internal surface of the first wall 102 of the section 100 that delimits the first slot 104.
The second portion 29 of each clamping bracket 27 comprises a plate-like element which, when the handle 10 is in the mounting configuration on the section 100, extends substantially parallel to the plane defined by the moveable wing and below the first wall 102 of the section 100 that delimits the first slot 104.
Such second portion 29 is provided with a unique threaded hole 30, where the threaded stem of a unique manoeuvring and clamping screw 31 is engaged.
The stem of each screw 31 is inserted with clearance into a through-hole 32 obtained in the box-shaped body 11.
The stem of each screw 31 ends in a head 33 housed in a seat 34 obtained in the box-shaped body 11 and connected to the corresponding through-hole 32.
Hence, each of the two through-holes 32 widens in a respective seat 34.
The through-holes 32 and the respective seats 34 are obtained in proximity of the opposite longitudinal ends of the box-shaped body 11 and are defined in an outer position with respect to the centre of the box-shaped body 11, than that of the elements defining the coupling between the first portion 28 of the respective clamping bracket 27 and the box-shaped body 11.
Each seat 34 is accessible from the outside of the box-shaped body 11 and, in particular, from the face 13 thereof when the covering plate 26 is in its second position.
More in detail, each of the two clamping brackets 27 comprises a substantially L-shaped body, the arms of which respectively define the first portion 28 and the second portion 29.
When the handle 10 is in the mounting configuration onto the frame (i.e. on the section 100), the two arms of each L-shaped bodies defining the first portion 28 and the second portion 29 of each of the two clamping brackets 27 respectively extend parallel to the rotation axis R and parallel to the resting face 12.
The first portion 28 of each clamping bracket 27 is coupled to the box-shaped body 11 with a coupling of the generally prismatic type configured so as to guide the sliding of the relative clamping bracket 27 along a direction parallel to the rotation axis R and hinder the rotation thereof about axes parallel to the rotation axis R.
In addition, such coupling is loose on a longitudinal plane of the box-shaped body 11 so as to allow the oscillation of the respective clamping bracket 27 for a defined oscillation angle on a longitudinal plane of the box-shaped body 11 and orthogonal to the resting face 12 of the latter.
The maximum sliding stroke that each of the two clamping brackets 27 may perform along a direction parallel to the rotation axis R is delimited by a pair of stop elements 35 and 36 that are spaced from each other along the longitudinal development of the respective first portion 28 and each of which is adapted to abut against a corresponding abutment surface 37 and 38 obtained in the box-shaped body 11.
With particular reference to the embodiment represented in the attached figures, the coupling of the generally prismatic type between the first portion 28 of each of the two clamping brackets 27 and the box-shaped body 11 is constituted by a respective groove or recess 39 that is obtained in the box-shaped body 11 in proximity of one of the two opposite longitudinal ends of the box-shaped body 11.
Each groove or recess 39 has a rectangular transverse section, extends in the direction parallel to the rotation axis R and has the face facing the centre of the box-shaped body 11 open for the insertion of a corresponding segment of the first portion 28 of the respective clamping bracket 27 through it.
In fact, the first portion 28 of each clamping bracket 27 has a segment with rectangular transverse section that is slidably axially housed in the respective groove or recess 39.
At the opposite longitudinal ends of such segment, transverse widenings are obtained defining the stop elements 35 and 36 that are adapted to rest against respective abutment surfaces 37 and 38 obtained at the opposite longitudinal ends of the respective groove or recess 39.
In particular, the resting between the stop elements 35 at the end of the first portion 28 farthest from the second portion 29 and the respective abutment surface 37 hinders the slipping off of the respective clamping bracket 27 from the box-shaped body 11 along a direction parallel to the rotation axis R.
The resting of the stop elements 36 on the end of the first portion 28 closest to the second portion 29 against the respective abutment surface 38 limits the sliding stroke of the respective clamping bracket 27 in the approaching sense to the box-shaped body 11 for clamping the same on the section 100.
Still with reference to the embodiment represented in the attached figures, each clamping bracket 27 is constituted by a substantially L-shaped body, the arm of which defining the first portion 28 is H or double T-shaped.
Each clamping bracket 27 - or rather the first portion 28 thereof - is held inside the respective groove or recess 39 by a member for at least partly closing the respective open face of the latter.
In the embodiment represented in the attached figures, such closing member is constituted by the guide body 21, which cooperates with the grooves or recesses 39 to obtain the generally prismatic coupling between the first portion 28 of each of the two clamping brackets 27 and the box-shaped body 11 serving as an element for holding the latter against the slipping off in the direction parallel to the longitudinal development of the box-shaped body.
However, alternative embodiments of the closing member or member for holding the clamping brackets 27 against the slipping off of the same in the direction parallel to the longitudinal development of the box-shaped body 11, cannot be excluded.
Gripping teeth 40 are obtained on the face of the second portion 29 of each clamping bracket 27. According to the present invention, each attachment plate 25 is mounted slidably onto the respective tab 24 with a toothed coupling.
The toothed coupling extends along the relative sliding direction between each attachment plate 25 and the respective tab 24 and the mutually meshing teeth develop in the direction transverse to the sliding direction (i.e. to the rotation axis R).
Generally, each tab 24 is provided with two opposite sides which extend in the direction orthogonal to the resting face 12 and along which a plurality of transverse teeth 41 is obtained, with which a corresponding plurality of teeth 42 meshes that are obtained in facing sides of the respective attachment plate 25.
Such toothed coupling allows a "stepped" and millimetric adjustment of the position of the attachment plate 25 with respect to the tab 24 and, thus, the overall height of the respective "fin" or "strip". In addition, it allows holding the attachment plate 25 in the attained desired adjustment position.
More in detail and with reference to the embodiments represented in the attached figures, each tab 24 has, for at least one longitudinal portion, a substantially Q (omega)-shaped symmetric cross section that has a central portion 240 from the sides 241 of which flat edges 242 extend.
The sides 241 extend along a plane orthogonal to the resting face 12 and orthogonal to the longitudinal development of the box-shaped body 11.
The flat edges 242 extend on a plane orthogonal to the resting face 12 and parallel to the longitudinal development of the box-shaped body 11.
A respective attachment plate 25 is fitted and guided on each tab 24.
Each attachment plate 25 has, for at least one longitudinal portion, a substantially C-shaped cross section, the edges 250 of the sides 251 of which are folded to form corresponding tabs which wrap around and at least partly overlap to the flat edges 242 of the tab 24.
Advantageously, the toothed coupling is defined between the folded edges 250 (i.e. tabs) of the longitudinal portion of the attachment plate 25 having a C-shaped cross section and the sides 241 of the longitudinal portion of the tab 24 having an Q (omega)-shaped cross section.
In particular, along the sides 241, a plurality of transverse teeth 41 is obtained with which a corresponding plurality of teeth 42 is engaged that are obtained in the facing folded edges 250 of the respective attachment plate 25.
Such toothed coupling allows the millimetric adjustment and accurate fixing of the position of the attachment plate 25 along the respective tab 24 and, thus, adjusting the height of the respective "fin" or "strip" as a function of the depth of the section 100.
Advantageously, on each tab 24, a graduated reference scale is provided that facilitates the aforementioned adjustment.
In addition, in a preferred embodiment, each tab 24 has at least one longitudinal groove 243 or slot in which a corresponding longitudinal projection or tongue 252 of the attachment plate 25 is guided.
In the embodiment represented in the attached figures, the groove 243 is defined by the central portion 240 of the longitudinal portion of the tab 24 with an omega-shaped cross section, while the tongue 252 is constituted by an enlarged portion that projects centrally from the attachment plate 25.
The groove 243 and the corresponding tongue 252 have a rectangular transverse section.
Such coupling allows stiffening and reinforcing the tab 24.
In addition, the attachment plates 25 may advantageously have a different longitudinal development so as to allow obtaining different overall lengths of the respective "fins" or "strips" (figures 1B and 1C).
In particular, each attachment plate 25 may have a height that is less or greater than the height of the respective tab.
With reference to the figure 1B it is observed that the attachment plate 25 is constituted by a unique longitudinal portion having a substantially C-shaped cross section and a lesser height with respect to that of the corresponding tab 24.
With reference to figure 1C it is observed that the attachment plate 25 has a first longitudinal portion having a substantially C-shaped cross section at the centre of which the tongue 252 projects and extending in a second longitudinal portion having a substantially T-shaped cross section, the shank of which connects to the tongue 252 without interruption.
The attachment plate 25 of figure 1C has a height greater than that of the respective tab 24.
Each attachment plate 25 is crossed by at least one hole 43 in which a corresponding clamping member 44 engages, of the screw or pin type, for clamping a rod 106.
As easily understandable to a man skilled in the art, the toothed coupling between the clamping plates and the respective tabs, which, in their entirety, form the "fins" or "strips", and their particular configuration may also be independently adopted from the adoption of the clamping brackets 27 subject of the present invention.
With reference to figures 1 to 4 it is now shown the assembly of the clamping brackets 27 with a handle 10 according to the present invention. Such assembly occurs during the production of the handle 10 which is thus supplied to the users in the assembled configuration and, in particular, with the clamping brackets 27 already mounted and positioned in the respective coupling seat provided in the box-shaped body 11.
As illustrated in figure 1, the clamping brackets 27 are mounted in the box-shaped body 11 by inserting the respective first portion 28 into the corresponding groove or recess 39 with the respective second portions 29 opposite to each other and facing the respective longitudinal end of the box-shaped body.
Subsequently, the guide body 21, the rotor 15 and the element 17 (i.e. sprocket) integral with are arranged into the box-shaped body 11 and the handgrip 14 is fixed to the rotor 15 through the screw 45. The guide body 21, in particular, hinders the slipping off of the clamping brackets 27 from the respective grooves or recesses 39 in the direction parallel to the longitudinal development of the box-shaped body 11.
The coupling between the stop element 35 and the respective abutment surface 37 instead prevents the slipping off of the respective clamping bracket 27 in the direction orthogonal to the resting face 12.
Maintaining the covering plate 26 in its second position, allows the stem of each screw 31 to be inserted into the respective through-hole 32 and to be screwed into the threaded hole 30 of the second portion 29 of the corresponding clamping bracket 27. The head 33 of each screw 31 is housed in the respective seat 34.
As easily evincible by a man skilled in the art, the through-holes 32 and the seats 34 are dimensioned so as to allow the desired oscillation of the respective clamping bracket 27 on a longitudinal plane of the box-shaped body 11 and orthogonal to the resting face 12.
Along the guide tracks defined by the guide body 21, the two racks 20 are arranged, each fixed to a respective slider 19 in turn provided with a respective tab 24 on which a respective selected attachment plate 25 is mounted, chosen of the height suitable for obtaining a "fin" or "strip" with the desired length as a function of the depth of the channel 101.
In addition, the cover 22 is mounted on the box-shaped body 11.
The handle 10 thus assembled is supplied to the users and, in particular, to the designated assembly operators.
It is observed that the clamping brackets 27 are already mounted onto the handle 10 and they can be easily manoeuvred from the outside through the respective screw 31 which, alone, serves both as a "manoeuvre" element and a clamping element.
The clamping brackets 27 are coupled to the box-shaped body 11 so as to be able to perform a defined sliding stroke along a direction parallel to the rotation axis R and a defined oscillation on a longitudinal plane of the box-shaped body 11 and orthogonal to the resting face 12.
The rotation of the clamping brackets 27 about axes parallel to the rotation axis R is instead hindered as well as their slipping off or detachment from box-shaped body 11.
Figures 5 to 9 instead show the mounting steps of a handle 10 according to the present invention on the section 100 forming the frame of a moveable wing of a window or door.
The handle 10 is applied onto the section 100 by inserting the respective "fins" or "strips" and the clamping brackets 27 into the first slot 104.
For such purpose, with the aim of preventing any interference with the first wall 102 delimiting the first slot 104, acting on the screws 31 allows the clamping brackets 27 to be singularly rotated approaching the resting face 12 and towards the centre of the box-shaped body 11 (figures 6 and 7).
It is observed that the heads 33 of the screws 31 are easily accessible from the outside of the box-shaped body 11 maintaining the covering plate 26 in its second position.
Once the clamping brackets 27 have been inserted into the first slot 104, they are returned to the straight or orthogonal position so that their first portion 28 and the respective screw 31 extend parallel to the rotation axis R and the second portion 29 extends below the first wall 102 and parallel thereto.
Screwing the screws 31, the two clamping brackets 27 are made to translate along the direction parallel to the rotation axis R approaching the first wall 102 that is thus clamped between its second portion 29 and the box-shaped body 11. The latter is thus fixed to the section 100.
Thus, the clamping brackets 27 serve as clamps.
The face 13 of the box-shaped body 11 is then covered by the covering plate 26.
Once the handle 10 has been mounted on the section 100, the "strips" or "fins" are housed in the channel 101 with the attachments plates 25 arranged at the second slots 107 and already adjusted at the desired height.
Lastly, the rods 106 are positioned in the channel 105 and fixed to the attachment plates 25 through respective clamping members 44 (figure 10).
The operation of the handle 10 is known to a person skilled in the art: the rotation of the handgrip 14 is transmitted to the racks 20 that slide in opposite senses along a direction parallel to the longitudinal development of the box-shaped body 11 and, thus, of the channel 101 dragging the "fins" or "strips" and with them the rods 106 constituting or being part of manoeuvre or closing rods of the window or door.
The handle subject of the present invention has the advantage of simplifying and quickening the mounting operations on a section defining the frame of a moveable wing of a window or door.
In fact, the handle according to the present invention is supplied to the assembly operators with the clamping brackets already positioned in it, mounted and assembled. Thus, the operators only have to act on the unique "manoeuvre" (i.e. manipulation) and fastening screw of each clamping bracket to insert the latter into the slot obtained on the section and fasten it against the wall delimiting such slot.
The handle subject of the present invention has the advantage of allowing a simple and safe millimetric and accurate adjustment of the overall height of the "fins" or "strips" as a function of the depth of the section before their insertion into the section.
The handle, in particular of the cremone bolt type applicable onto the frame of a moveable wing of a window or door, thus conceived can be subjected to numerous modifications and variants, all falling within the invention as defined by the appended claims; in addition all details can be replaced by technically equivalent elements. In practice, the material used, as well as the dimensions, may vary according to the technical requirements.
