Definitions
- the present invention refers to a lifting-lowering and sliding group for door or window wings.
- Sliding wings doors and windows which, in general terms, comprise a fixed frame which defines the opening of the door or window and to which at least one wing, able to slide horizontally between a closed position and an open position of the opening and vice versa, is associated.
- wings have long been known of the so called “lift and slide” type, that is, in which each wing is associated to the frame by means of a respective lifting-lowering and sliding group which is manoeuvred by a control handle.
- Such a group makes it possible to lift the wing from the respective sliding guide, with consequent detachment from the latter of the sealing gasket, before being able to slidingly pull it and, subsequently, lower it again re-establishing the contact between the sealing gaskets and the sliding guide.
- such a lifting-lowering and sliding group of the known type comprises at least two carriages which are associated to the lower crossbar of a wing and of which one, that is the main or front carriage, precedes the other, that is the secondary or rear carriage, in the sliding direction of the wing for closing the opening of the door or window, wherein the two carriages are joined to one another by a connecting rod.
- Each of the two carriages in turn comprises a support body provided with wheels which engage in the sliding guide of the wing and an attachment body to the lower crossbar of the wing.
- Such an attachment body is associated with the respective support body in a mobile manner on the vertical plane with a combined translation motion along the direction parallel to the sliding direction (horizontal direction) and along the direction orthogonal to it (vertical direction) so as to be able to be lifted and lowered with respect to it.
- the lifting or lowering motion of the attachment body and, therefore, of the wing to which it is fixed, with respect to the support body of the main carriage is controlled by means of a manoeuvring mechanism operated by the control handle and is transmitted to the attachment body of the secondary carriages by the rods that connect the carriages.
- the control handle After having brought the wing back in the closed position of the opening of the door or window, the control handle is made to rotate by 180° upwards so as to move the attachment bodies of the two carriages towards the corresponding support bodies and, therefore, bring the wing, which is fixed to them, back in the lowered position with the sealing gaskets in contact with the sliding guide.
- Some known devices are of the connecting rod and crank type and are applied to the control handle so as to prevent its return rotation to the closed position, others are of the friction type and are applied to the organs for transmitting the motion from the handle to the manoeuvring mechanism of the two carriages, again others are applied to the carriages themselves.
- devices comprising springs interposed between the attachment body and the support body of each carriage.
- a further drawback consists in the fact that such devices do not make it possible to modify the degree of the springs reaction in function of the weight of the wing or to recover possible coupling clearances which can generate also in use, unless springs or the various components are replaced with laborious interventions that require the disassembly and the re-assembly of the entire window or door frame.
- the main object of the present invention is that of avoiding the drawbacks of the prior art.
- one object of the present invention is that of making a lifting-lowering and sliding group for door or window wings which makes it possible to contrast the spontaneous rotation of the control handle from the open position to the closed position for the entire amplitude of its rotation angle, i.e. for the entire lifting-lowering stroke of the wing.
- a further object of the present invention is that of making a lifting-lowering and sliding group for door or window wings that allows to reduce the force that a user must apply to the control handle in order to bring the wing from the lowered position to the lifted position and vice versa.
- Yet another object of the present invention is that of making a lifting-lowering and sliding group for door or window wings which makes it possible to modify the degree of reaction of the springs in a simple and rapid manner even when the door or window frame is in the mounted configuration and without requiring disassembly and re-assembly operations.
- Yet another object of the present invention is that of making a lifting-lowering and sliding group for door or window wings having a low number of components, assembled with one another in a particularly simple and functional manner.

- a sealing gasket 103 is fixed to the lower crossbar 104 of the wing 102, so that, when the wing 102 is in the closing position of the door or window opening, an air and/or water tight seal is created between the wing 102 and the respective sliding guide.
- the main carriage 11a has an end associated to a manoeuvring mechanism 12 that is operated by a control handle 105 that is mounted on the wing 102.
- organs for locking the wing 102 in the closed position are not represented since they are of the known type and are operated by the same control handle 105.

Abstract
Description
- The present invention refers to a lifting-lowering and sliding group for door or window wings.
- Sliding wings doors and windows are known which, in general terms, comprise a fixed frame which defines the opening of the door or window and to which at least one wing, able to slide horizontally between a closed position and an open position of the opening and vice versa, is associated.
- Conventionally, the air or water-tight seal between the wing and the respective sliding guide formed in the frame is obtained by means of so called "brush" gaskets.
- "Brush" gaskets, however, do not make it possible to achieve levels of air or water seal comparable to those that can be reached, on the other hand, with gaskets made up of tubes, bands or similar, made from polymeric materials like, for example, Dutral®.
- The use of such last gaskets, however, is limited by the excessive friction which would be generated during the sliding of the wing and which would make the opening and closing manoeuvres of the opening of the door or window difficult.
- In order to avoid such a drawback, wings have long been known of the so called "lift and slide" type, that is, in which each wing is associated to the frame by means of a respective lifting-lowering and sliding group which is manoeuvred by a control handle.
- Such a group makes it possible to lift the wing from the respective sliding guide, with consequent detachment from the latter of the sealing gasket, before being able to slidingly pull it and, subsequently, lower it again re-establishing the contact between the sealing gaskets and the sliding guide.
- In general terms, such a lifting-lowering and sliding group of the known type comprises at least two carriages which are associated to the lower crossbar of a wing and of which one, that is the main or front carriage, precedes the other, that is the secondary or rear carriage, in the sliding direction of the wing for closing the opening of the door or window, wherein the two carriages are joined to one another by a connecting rod.
- Each of the two carriages in turn comprises a support body provided with wheels which engage in the sliding guide of the wing and an attachment body to the lower crossbar of the wing. Such an attachment body is associated with the respective support body in a mobile manner on the vertical plane with a combined translation motion along the direction parallel to the sliding direction (horizontal direction) and along the direction orthogonal to it (vertical direction) so as to be able to be lifted and lowered with respect to it. The lifting or lowering motion of the attachment body and, therefore, of the wing to which it is fixed, with respect to the support body of the main carriage is controlled by means of a manoeuvring mechanism operated by the control handle and is transmitted to the attachment body of the secondary carriages by the rods that connect the carriages.
- Starting from the closed configuration of the opening of the door or window - in which the wing is lowered with the sealing gaskets in contact with the respective sliding guide - in order to open the door or window it is necessary, in general, to rotate the handle by about 180° downwards. Such a rotation actuates, by means of transmission organs of the known type, the manoeuvring mechanism so as to move the attachment bodies of the carriages and, therefore, the wing fixed to them, away from and upwards with respect to the corresponding support bodies thus lifting the wing and detaching the sealing gaskets from the sliding guide.
- It is thus possible to make the wing slide in the opening/closing direction of the door or window by means of wheels of the support bodies of the two carriages.
- After having brought the wing back in the closed position of the opening of the door or window, the control handle is made to rotate by 180° upwards so as to move the attachment bodies of the two carriages towards the corresponding support bodies and, therefore, bring the wing, which is fixed to them, back in the lowered position with the sealing gaskets in contact with the sliding guide.
- When the wing is in the lifted position, it tends, by action of its weight, to be brought back in the lowered position, so that its sliding is obstructed, if not even prevented.
- In order to avoid such a drawback, solutions are already known which provide for the use of devices which, when the wing is in the lifted position, contrast its weight preventing its spontaneous return to the lowered position.
- Some known devices are of the connecting rod and crank type and are applied to the control handle so as to prevent its return rotation to the closed position, others are of the friction type and are applied to the organs for transmitting the motion from the handle to the manoeuvring mechanism of the two carriages, again others are applied to the carriages themselves.
- Amongst these latter, in particular, devices are known comprising springs interposed between the attachment body and the support body of each carriage.
- These last safety devices of the known type have, however, some drawbacks.
- Among these it should be reminded that such devices are active only for a fraction of the amplitude of the rotation angle of the control handle and, therefore, only for a fraction of the lifting/lowering stroke of the wing.
- A further drawback consists in the fact that such devices do not make it possible to modify the degree of the springs reaction in function of the weight of the wing or to recover possible coupling clearances which can generate also in use, unless springs or the various components are replaced with laborious interventions that require the disassembly and the re-assembly of the entire window or door frame.
- The main object of the present invention is that of avoiding the drawbacks of the prior art.
- Within this general object, one object of the present invention is that of making a lifting-lowering and sliding group for door or window wings which makes it possible to contrast the spontaneous rotation of the control handle from the open position to the closed position for the entire amplitude of its rotation angle, i.e. for the entire lifting-lowering stroke of the wing.
- A further object of the present invention is that of making a lifting-lowering and sliding group for door or window wings that allows to reduce the force that a user must apply to the control handle in order to bring the wing from the lowered position to the lifted position and vice versa.
- Yet another object of the present invention is that of making a lifting-lowering and sliding group for door or window wings which makes it possible to modify the degree of reaction of the springs in a simple and rapid manner even when the door or window frame is in the mounted configuration and without requiring disassembly and re-assembly operations.
- Yet another object of the present invention is that of making a lifting-lowering and sliding group for door or window wings having a low number of components, assembled with one another in a particularly simple and functional manner.
- These and yet other objects are achieved with a lifting-lowering and sliding group for door or window wings as defined in claim 1.
- Further characteristics are specified in the dependent claims.

sealing gasket 103 is fixed to thelower crossbar 104 of thewing 102, so that, when thewing 102 is in the closing position of the door or window opening, an air and/or water tight seal is created between thewing 102 and the respective sliding guide. - The
group 10 comprises at least one carriage and, in general, at least twocarriages main carriage 11a, precedes the other one, generally indicated as the rear orsecondary carriage 11b, with respect to the sliding direction A2 for closing thewing 102. - Between the
main carriage 11a and thesecondary carriage 11b there could be at least one further intermediate carriage. - The
main carriage 11a has an end associated to amanoeuvring mechanism 12 that is operated by acontrol handle 105 that is mounted on thewing 102. - Moreover, there are provided organs for locking the
wing 102 in the closed position, these organs are not represented since they are of the known type and are operated by thesame control handle 105. - For the sake of clarity and simplicity, in the rest of the description, the two carriages shall be indicated as "main carriage" and "secondary carriage", it being understood that one of them is directly connected to the manoeuvring mechanism that is operated by the control handle and the other one is at the opposite end of the series of carriages which can be arranged to support the
wing 102. - The end of the
main carriage 11a opposite to that associated to themanoeuvring mechanism 12 is fixed at the end of a connectingrod 13 extending parallel to the sliding direction A and the opposite end of which is fixed to an end of thesecondary carriage 11b. - The connecting
rod 13 acts as a transmission and manoeuvre mechanism between themain carriage 11a and thesecondary carriage 11b. - In the present description elements that are common to the two carriages shall be indicated with the same reference numerals followed by the letter "a", if they refer to the
main carriage 11a, and by the letter "b", if they refer to thesecondary carriage 11b. - Each of the two carriages, main 11a and secondary 11b, comprises in turn a
support body wheels respective pins wing 102 and which are housed in the sliding guide, schematically indicated by theline 106 in figures from 3a to 8, so as to allow the translation of thewing 102 along the sliding direction A. - Each of the two carriages, main 11a and secondary 11b, moreover, comprises an
attachment body wing 102, which, in particular, can be fixed, for example throughscrews lower crossbar 104 of thewing 102. - Each
attachment body respective support body wing 102 with a relative combined translation motion along the sliding direction A and along a direction B orthogonal to it for lifting and lowering thewing 102 with respect to thesupport body sliding guide 106. - Considering the
group 10 in the configuration assembled onto awing 102, the sliding direction A is horizontal and the direction B orthogonal to it is the vertical one. - One particular characteristic of the present invention consists in the fact that the
support body guide body elastic means support body respective counter element lower crossbar 104 of thewing 102. - Wherein the
counter element attachment body respective guide body guide bodies respective support body - That is, the
guide body 19a of themain carriage 11a is defined at the end of therespective support body 14a opposite to that associated to themanoeuvring mechanism 12. - The
guide body 19b of thesecondary carriage 11b is defined at the end of therespective support body 14b opposite to that fixed to the connectingrod 13. - Both
guide bodies wing 102; i.e. they extend horizontally so that the elastic force exerted by the respective elastic means 20a, 20b that are guided on them is directed parallel to the sliding direction A of thewing 102. Advantageously, eachguide body respective support body - As shall become clearer from the following detailed description, the guide rod that integrates the
guide body 19a of themain carriage 11a coincides with a length of the connectingrod 13. - As schematically represented in figures from 3a to 4b, the
main carriage 11a and thesecondary one 11b assume a first operative configuration and a second operative configuration respectively "with thewing 102 lowered" and "with thewing 102 lifted". - In the first configuration ("with the
wing 102 lowered",figures 3a and 3b ), theattachment bodies corresponding support bodies elastic means respective support body counter element - In such a first configuration, the
wing 102, which is fixed to theattachment bodies sliding guide 106 with thegasket 103 in seal contact with the latter. - In the second configuration ("with the
wing 102 lifted",figures 4a and 4b ), theattachment bodies corresponding support bodies elastic means respective support body counter element - In such a second configuration, the
wing 102, which is fixed to theattachment bodies guide 106. - As can be noted in the attached figures, the second compression state of the
elastic means wing 102") is less than that of the first compression state, so that theelastic means secondary carriages wing 102 lowered") to the second configuration ("with thewing 102 lifted") and contrast the weight of thewing 102 when the carriages are in the second configuration ("with thewing 102 lifted"), preventing its spontaneous return to the first configuration ("with thewing 102 lowered"). - According to a further particular characteristic of the present invention, at least one of the two carriages, main 11a and secondary 11b, in particular at least the
secondary carriage 11b, comprises adjusting means 22a, 22b of the first compression state of the respectiveelastic means - In greater detail and with reference to
figure 2 , thesupport body 14a of themain carriage 11a consists of twoside walls 140a facing one another and parallel to the lying plane of thewing 102 and between which are arranged thewheels 15a, thepins 16a of which are supported inholes 141a obtained in the twoside walls 140a. - Each of the two
side walls 140a comprises, at one end, ahole 142 in which themanoeuvring mechanism 12 articulates and, at the opposite end, holes 143, in which thepins 23 of aspacer 24 are fitted in. - The
attachment body 17a of themain carriage 11a is L-shaped with one branch extending parallel to the sliding direction A and which is intended to be fixed to thelower crossbar 104 of thewing 102 and the other branch extending orthogonal to the first and which is intended to be fixed to the rib of thewing 102. - The
attachment body 17a has anappendage 170a which extends towards thesupport body 14a and in which aslot 171a is defined, the slot being rectilinear, parallel to the lying plane of thewing 102 and inclined with respect to the forward movement direction A. - Along the
slot 171a apin 172a is mobile, thepin 172a being fixedly attached to thesupport body 14a. - In practice, the
slot 171a is a through slot formed in theappendage 170a and thepin 172a consists of a pin the opposite ends of which are fixed inholes 144a obtained in the twoside walls 140a. - At the angle portion of the
attachment body 17a afurther hole 173 is obtained for the articulation of themanoeuvring mechanism 12, as described later on in the description. - One end of the connecting
rod 13 is fixed inside thespacer 24, by means ofdowels 25. - The same connecting
rod 13, or better, a length thereof extending from the end of thesupport body 14a opposite to that associated to themanoeuvring mechanism 12, acts as aguide body 19a of theelastic means 20a. - The latter advantageously consist of at least one cylindrical or conical-spiral torsion spring coaxially mounted to the connecting
rod 13 with one end resting on an abutment surface defined by thespacer 24 of thesupport body 14a and with the opposite end resting on therespective counter element 21a. - The
counter element 21a is fixed to thelower crossbar 104 of thewing 102 by means ofdowels 210a and projects at the bottom in a plate that is orthogonal to the lying plane of thewing 102 and in which aslot 211a is obtained extending parallel to the direction B and in which the connectingrod 13 is inserted with a clearance, so that between thecounter element 21a and the connecting rod 13 (guide rod of theelastic means 20a) there can be a relative sliding motion along the sliding direction A (horizontal) of thewing 102 and along the direction B orthogonal to it (vertical). - The adjusting means 22a of the compression state, or better, of the first compression state, of the
elastic means 20a are defined at the end of thesupport body 14a opposite to the end of the latter associated to themanoeuvring mechanism 12 and are suitable for modifying the position of thecounter element 21a with respect to thesupport body 14a when the main carriage is in the first configuration (figures 3a and 3b ) before that thecounter element 21a is mounted on thewing 102. - In particular, the adjusting means 22a comprise an adjusting organ that consists of a
nut 220 which is screwed on at least one threaded length of theguide body 19a (connecting rod 13) and that, in the mounting phase of thegroup 10 and when themain carriage 11a is in the first configuration, rests against thecounter element 21a on the side opposite with respect to theelastic means 20a. - In such conditions and before fixing the
counter element 21a to thelower crossbar 104 of thewing 102, by acting on thenut 220 it is possible to modify the first compression state (pre-load) of theelastic means 20a. - After having adjusted the first compression state (pre-load) of the
elastic means 20a to the desired value, temporarily keeping thenut 220 in position, the assembly of thegroup 10 is completed by fixing thecounter element 21a to thelower crossbar 104 of thewing 102. - Once it has been mounted, the
nut 220 is unscrewed and removed from thecounter element 21a by a distance equal to at least the relative sliding between it and theguide body 19a (connectingrod 13;figures 5 and 6 ). - Again with reference to
figure 2 , thesupport body 14b of thesecondary carriage 11b consists of twoside walls 140b facing one another and parallel to the lying plane of thewing 102 and between which are arranged thewheels 15b, thepins 16b of which are supported inholes 141b obtained in the twoside walls 140b. - Each of the two
side walls 140b comprises, at each of the two opposite ends,respective holes pins respective spacer - The
attachment body 17b of thesecondary carriage 11b consists of a plate intended to be fixed to thelower crossbar 104 of thewing 102. - In a completely similar way to the
attachment body 17a of themain carriage 11a, also theattachment body 17b has anappendage 170b which extends towards thesupport body 14b and in which aslot 171b is defined, the slot being rectilinear, parallel to the lying plane of thewing 102 and inclined with respect to the forward movement direction A completely identical to theslot 171a. - Along the
slot 171b apin 172b is mobile, the pin being fixedly attached to thesupport body 14b. - In practice, the
slot 171b is a through slot formed in theappendage 170b and thepin 172b consists of a pin the opposite ends of which are fixed inholes 144b formed in the twoside walls 140b. - One end of the connecting
rod 13 is fixed, by means ofdowels 30, inside thespacer 28. - The
guide body 19b of theelastic means 20b consists of a guide rod that has one end fixed inside thespacer 29 by means ofdowels 31. - The elastic means 20b advantageously consist of at least one cylindrical or conical-spiral torsion spring coaxially mounted to the
guide body 19b with one end resting on an abutment surface defined by thespacer 29 of thesupport body 14b and with the opposite end resting on therespective counter element 21b. - The
counter element 21b is fixed to thelower crossbar 104 of thewing 102 by means ofdowels 210b and projects at the bottom in a plate that is orthogonal to the lying plane of thewing 102 and in which aslot 211b is formed extending parallel to the direction B and in which theguide body 19b is inserted with clearance, so that between thecounter element 21b and theguide body 19b (guide rod of theelastic means 20b) a relative sliding movement can occur along the sliding direction A (horizontal) of thewing 102 and along the direction B orthogonal to it (vertical). - The end of the
guide body 19b opposite to the one fixed to thespacer 29 has acollar 190 for stopping the relative sliding of thecounter element 21b. - The
counter element 21b is associated with anattachment block 32 that is fixed to thelower crossbar 104 of thewing 102 with the interposition of the adjusting means 22b of the compression state, or better of the first compression state, of theelastic means 20b. - In greater detail, the adjusting means 22b are configured in order to modify the position of the
counter element 21b with respect to theattachment block 32. - Such adjusting means 22b comprise an adjusting
screw 221 extending parallel to theguide body 19b (guide rod) and that passes a throughhole 212 obtained in thecounter element 21b. - Said adjusting
screw 221 has an end engaged in a threadedhole 33 which is obtained in theattachment block 32 and the opposite end provided with an abutment element consisting of thehead 222 whereon thecounter element 21b stops (figure 7 and 8 ). - In the head 222 a
seat 223 is formed for engaging with a manoeuvring tool. - As can be seen from the attached figures, considering the
group 10 in the assembled configuration on a door or window wing, the adjusting means 22b of the compression state of theelastic means 20b of thesecondary carriage 11b are accessible from the outside. It is not excluded that the adjusting means 22a of the compression state of theelastic means 20a of themain carriage 11a, can be configured in a completely identical manner to that of the adjusting means 22b of the compression state of theelastic means 20b of thesecondary carriage 11b, i.e. of the outermost carriage. Themanoeuvring mechanism 12 comprises a ternary element consisting of twoplates 120 facing one another and parallel to the lying plane of thewing 102 and each of which has three holes,first holes 121,second holes 122 andthird holes 123, respectively. - The
first holes 121 house the ends of afirst pin 124 around which the end of a connectingrod 125 is articulated, the opposite end of the connectingrod 125 is articulated to thesupport body 14a of themain carriage 11a by means of asecond pin 126 mounted in theholes 142 of theside walls 140a. - The
second holes 122 house the ends of athird pin 127 around which theattachment body 17a of themain carriage 11a is articulated by means of thehole 173. - The
third holes 123 house the ends of afourth pin 128 inserted in ahole 129 of acontrol rod 130 associable to the upright of thewing 102 in a sliding manner along the direction B orthogonal to the sliding direction A and controlled, by means of transmission organs which have not been represented since they are of the known type, by thehandle 105. - In light of the attached figures and of the description made above, a man skilled in the art will not have any difficulty in understanding how the present invention operates and its advantages.
- In particular, with reference to
figures 3a-3b and4a-4b in these, thegroup 10 according to the present invention is illustrated respectively in the first configuration ("with thewing 102 lowered") and in the second configuration ("with thewing 102 lifted"). - In the first configuration (
figures 3a and 3b ), the first and thefourth pin manoeuvring mechanism 12 are substantially aligned with thesupport bodies main carriage 11a and of thesecondary carriage 11b. - The
attachment bodies main carriage 11a and of the secondary one 11b are in a lowered position with respect to thecorresponding support body pins respective slot - In said first configuration, the
elastic means - From such a first configuration, by rotating the
handle 105 by around 180° downwards, as indicated by the arrow F1 infigure 3a , the rotation of the ternary element is generated, as indicated by the arrow F2 infigure 3b . Since thewing 102, which, in such a first configuration is positioned to close the opening of the door or window, is constrained by the fixedframe 101, such a rotation generates the sliding of thesupport bodies main carriage 11a and of the secondary one 11b in the closing direction of thewing 102 and, thanks to the coupling betweenslots pins attachment bodies wing 102 to which they are fixed, with respect to thesupport body main carriage 11a and secondary one 11b. - The
group 10 and, therefore, thewing 102 to which it is applied thus assume the second configuration ("with liftedwing 102";figures 4a and 4b ) in which the first and thefourth pin manoeuvring mechanism 12 are substantially aligned along the direction B. - The
attachment bodies main carriage 11a and of the secondary one 11b are in a lifted position with respect to thecorresponding support body pins respective slot - In said second configuration, the
elastic means - The passage from the first to the second configuration is assisted by the thrust exerted by the
elastic means - Once the second configuration ("with lifted
wing 102") has been reached, theelastic means wing 102 preventing its return to the lowered position. - The elastic reaction of the
elastic means wing 102 thanks to the adjusting means 22a, 22b, of which, those applied to thesecondary carriage 11b are accessible from the outside also when thegroup 10 is in the assembled configuration on the window frame. - In practice it has been seen how the subject-matter of the present invention makes it possible to achieve the predetermined objects.
- The lifting-lowering and sliding group according to the present invention, indeed, thanks to the particular location and arrangement of the elastic means, makes it possible to facilitate the opening manoeuvre of the wing, reducing the force that a user must exert on the control handle in order to bring the wing from the lowered position to the lifted one and, consequently, to reduce the dimensions of the arm of the control handle itself.
- Thanks to the particular location and arrangement of the elastic means, the lifting-lowering and sliding group according to the present invention makes it possible to effectively contrast the spontaneous return of the wing from the lifted position to the lowered position for the entire lifting/lowering stroke thereof, i.e. the entire amplitude of the corresponding rotation angle of the control handle.
- Thanks to the provision of the adjusting means of the compression state of the elastic means it is, moreover, possible to adjust the elastic reaction as a function of the weight of the wing.
- The particular configuration and arrangement of the adjusting means of the compression state of the elastic means mounted on the secondary carriage - that is of the carriage at the end of the wing opposite to that whereon the control handle is mounted - allow to adjust the elastic reaction even when the group is in the assembled configuration, in a simple and rapid manner, without it being necessary any disassembly and reassembly operation.
- Such adjusting means, indeed, are easily accessible below the wing and it is sufficient to use a manoeuvring tool to carry out the adjustment intervention.
- The lifting-lowering and sliding group for door or window wings thus conceived is subject to numerous modifications and variants, all covered by the invention; moreover, all the details can be replaced by technically equivalent elements. In practice the materials used, as well as the dimensions, can be any according to the technical requirements.
