Description

This invention relates to a selector, a relative selection mechanism, a relative stroke control mechanism and the relative methods of reconfiguration in an operating kit for a door or window. Moreover, this invention also relates to a method for producing and installing one or more components (striker elements, contact elements or selectors) of the operating kit.
The doors and windows are formed by a fixed frame, which is normally fixed to a wall of an operating space to which the door or window may allow or inhibit access. The fixed frame comprises a profile, having one or more grooves for fixing one or more striker elements (known, in the jargon of the trade, also with the term strikers). Moreover, the door or window comprises a sash, which is movably connected to the frame, in such a way as to allow a movement of the sash from a closed position to an open position. As is known, the open positions may have different configurations. For example, the side-hung opening is known, wherein the sash is rotated about a first side of the frame, and a tilted opening, where the sash is rotated about a second side, perpendicular to the first side. It should be noted that, normally, the tilted opening has a limited angle of opening. The side-hung opening, on the other hand, normally has a larger operating space, with angles which can reach up to 180 degrees.
The doors and windows of this type comprise an operating element, usually a handle, which when rotated appropriately allows the setting to the closed, side-hung and tilted opening positions. The position is determined by the angular rotation of the handle.
In order to obtain these positions, the door or window is equipped with a drive unit which transfers the rotation of the handle to one or more striker elements of the door or window. More in detail, one or more striker pins are connected to the drive unit, which is positioned on the sash. The reciprocal perimeter position between the striker pins and said one or more striker elements on the profile of the frame determines the position of the sash.
The needs for adapting the doors or windows to the various needs have generated a number of solutions for the striker elements which are very high and diversified, at the expense of the production efficiency of these components. For example, in order to adapt the opening of the handle with the left hand or with the right hand, different parts are necessary, with a reduced standardisation and rigidity also during the production and installation steps (for example, post-order alterations).
Another mechanism of the operating kit of a door or window is that which makes it possible to establish the maximum stroke which can be performed with the operating element, that is to say, in other words, the rotation which the handle may perform.
Also in this case, in order to obtain a variation in the stroke, different parts are necessary, mounted in a different manner and in any case to be provided well before the installation.
Systems illustrating selector solutions with the above disadvantages are described in the following documents: EP2754805A2 and FR2722527A1 .
The aim of this invention is to provide a selection mechanism and a method which overcome the above-mentioned problems of the prior art.
Said aim is fully achieved by the selection mechanism and by the method according to the invention as characterised in the appended claims.
According to an aspect of the invention, the invention provides a selector for an operating kit of a door or window, including a sash rotating relative to a respective fixed frame about a first axis of rotation, parallel to a first side of the frame, and/or a second axis of rotation, perpendicular to the first side of rotation.
The selector is configured to be associated with the sash. The selector extends along a longitudinal direction between a first and a second end.
The selector comprises a facing surface, facing, in use, towards the frame.
The selector comprises a tilting pin. The tilting pin rises from the facing surface along a normal direction, perpendicular to the facing surface. The tilting pin is positioned, along the longitudinal direction, at a first distance from the first end of the selector. The tilting pin is positioned, along the longitudinal direction, at a second distance from the second end of the selector.
Advantageously, the selector comprises a first connecting profile, positioned at the first end of the selector.
The selector comprises a second connecting profile, positioned at the second end of the selector.
Said first and second connecting profiles being configured to connect with a respective first and/or second interface of a drive unit which transmits a movement of an operating element of the door or window to the selector.
More specifically, the first and second connecting profiles are interchangeable, in such a way that both the first and the second connector can be connected to the first and/or the second interface of the drive unit.
This feature allows the position of the selector to be reversed by 180 degrees by varying, in effect, the position of the tilting pin relative to the striker unit. This variation in position determines the possibility of varying an actuating configuration of the door or window, between one with the right hand actuation and one with the left hand actuation (corresponding to the fact that a handle of an operating element is to be rotated downwards or upwards to determine the tilted position of the door or window). Obviously, this feature allows an increase in the assembly flexibility and (re)configuration of the door or window even post-design, as well as allowing a standardisation of the parts and, therefore, a general increase in the production efficiency.
Advantageously, the first and the second distances are different from each other. This asymmetry makes it possible to define a variation of the relative position between the striker unit and the tilting pin, without having to vary the position of the striker unit, and therefore in a quick, easy and controllable manner.
The ratio between the first and the second distance is between 0.4 and 0.8, preferably between 0.5 and 0.7.
These dimensional ratios allow the tilting pin to travel along the longitudinal direction due to the rotation of the selector which is suitable for applications on the doors or windows and which, above all, allows a contact suitable for the tilting position to be obtained.
According to an embodiment, the selector comprises a base surface, opposite the facing surface. The first connecting profile and the second connecting profile comprise a respective connecting hole and a respective groove, made on the base surface and open at the respective first and second end of the selector.
This allows the interface of the drive unit to be inserted adequately inside the groove with a respective connecting pin which inserts in the hole. This configuration guarantees a complete flatness of the coupling, which may therefore be inserted in the corresponding housings on the sash of the door or window.
According to an embodiment of the selector alternative to that with the first and second distances different, the first connecting profile and the second connecting profile comprise a respective plurality of connecting holes, spaced from each other along the longitudinal direction. Each of said connecting holes is configured to receive a pin for connecting the drive unit. It should be noted that the distance between the connecting holes of each of said first and second connecting profiles is the same, to always allow the connecting holes to be matched with the connecting pins of the drive unit.
In this way, the selector can be translated directly along the longitudinal direction, moving it according to the spacing determined by the distance along the longitudinal direction between the connecting holes of said plurality. This solution basically solves the same technical problem of improving the standardisation of the parts and their reconfigurability on the door or window.
According to an aspect of the invention, the invention provides a selection mechanism for setting up a position of a door or window. The door or window includes a sash rotating relative to a respective fixed frame about a first axis of rotation, parallel to a first side of the frame, and a second axis of rotation, perpendicular to the first side of rotation. Said door or window can be configured in the side-hung configuration, wherein the sash rotates relative to the frame about the first axis of rotation, and a tilted opening configuration, wherein the sash rotates relative to the frame about the second axis of rotation.
The selection mechanism comprises a selector, according to any of the features described in the invention.
The selection mechanism comprises a striker unit. The striker unit is configured to be associated with the frame. The striker unit comprises a tipping wall. The tipping wall is configured to make contact, in the tilting opening configuration, with the tilting pin along a transversal direction, perpendicular to the longitudinal direction.
According to an embodiment, the tipping wall comprises a normal portion, parallel to the normal direction, and a transversal portion, which, starting from the normal position, extends along the transversal direction.
In this way, the tilting pin, when rotating, makes contact with the transversal portion.
The normal portion comprises a contact surface, configured to come into contact with the tilting pin. Preferably, the contact surface is a curved surface.
This allows a sort of sliding rolling of the tilting pin to be accompanied on the tipping wall.
Preferably, the contact pin forms a tilting pin and is mushroom-shaped. The mushroom comprises a head, having a top surface, facing towards the outside. Said top surface is preferably curved in such a way as to allow a partial rolling of the tilting pin on the tipping wall or on the facing surface.
According to an aspect of the invention, the invention provides a stroke control mechanism for controlling a stroke of the operating element of the door or window. The stroke control mechanism comprises a selector according to any of the features described in the invention.
The stroke control mechanism comprises a slider. The slider includes an end of stroke surface SFC. The slider is movable along the longitudinal direction, in response to a movement of the operating element, between a first limit position, wherein the end of stroke surface is spaced from the contact pin of the selector along the longitudinal direction, and a second limit position, wherein the end of stroke surface is in contact with the contact pin of the selector.
According to an embodiment, the contact pin defines an end of stroke pin, comprising a first stop surface. The first stop surface faces towards the first connecting profile of the selector. The first stop surface is perpendicular to the longitudinal direction and configured to come into contact with the end of stroke surface of the slider in the second limit position of the slider with the first connecting profile connected to the operating kit.
The contact pin comprises a second stop surface. The second stop surface faces towards the second connecting profile of the selector. The second stop surface is perpendicular to the longitudinal direction and configured to come into contact with the end of stroke surface of the slider in the second limit position of the slider with the second connecting profile connected to the operating kit.

The kit comprises a drive unit, configured for transmitting an actuation of the operating element to the selection mechanism, for moving it in such a way as to vary the configuration of the door or window between the side-hung configuration and the tilted opening configuration.
According to an aspect of the invention, the method for reconfiguring a door or window, including a sash rotating relative to a respective fixed frame about a first axis of rotation, parallel to a first side of the frame, and a second axis of rotation, perpendicular to the first side of rotation, is configurable in a side-hung configuration, wherein the sash rotates relative to the frame about the first axis of rotation, and a tilted opening configuration, wherein the sash rotates relative to the frame about the second axis of rotation.
The method comprises the steps of preparing an operating element, configured for being actuated by a user to open or close the door or window in different configurations, a selection mechanism according to any one of the features described in this invention and a drive unit, configured for transmitting an actuation of the operating element to the selection mechanism, for moving it in such a way as to vary the configuration of the door or window between the side-hung configuration and the tilted opening configuration.
The method comprises a step of configuring the door or window in a first actuating configuration, characterised by a first type of movement of the operating element. Said configuration step comprising a step of connecting a first interface of the drive unit to the first connecting profile.
Advantageously, the method comprises a step of reconfiguring the door or window, to bring it to a second actuating configuration, characterised by a second type of movement of the operating element. Said reconfiguration step comprising a step of connecting the first interface of the drive unit to the second connecting profile. In particular, said reconfiguration step comprises a step of rotating the selector by 180 degrees, in such a way as to connect the first interface of the drive unit to the second connecting profile.
Preferably, when there is also a rod of the drive unit, in the first actuating configuration, the second connecting profile is connected to a second interface of the drive unit, positioned on the rod of the drive unit, whilst, in the second actuating configuration, the first connecting profile is connected to the second interface of the drive unit.
According to an embodiment, wherein each of said first and second connecting profiles includes a respective plurality of connecting holes, spaced longitudinally from each other, the reconfiguration step comprises a step of longitudinal movement of the selector, for coupling the connecting pins of the drive unit to different connecting holes, moved longitudinally relative to those to which the drive unit was connected in the initial configuration step.

The selector 1 comprises a base surface 12, opposite the facing surface 10.
The selector 1 has a planar shape (perpendicular to the normal direction N) and preferably has a rectangular shape (in the form of a flat rod).
The selector 1 comprises a first connecting profile 13. The first connecting profile 13 is positioned at the first end 1A of the selector 1. The first connecting profile 13 comprises a respective connecting hole 131. The connecting hole 131 passes from the facing surface 10 to the base surface 12.
The first connecting profile 13 comprises a respective groove 132. The groove of the first connecting profile 13 is made on the base surface 12. The groove of the first connecting profile 13 is open longitudinally on the first end 1A of the selector 1 whilst it is closed along the transversal direction T by respective containing portions. The connecting hole 131 is open on the groove 132.
The connecting hole 131 and the respective groove are configured to receive a connecting pin PC rising from a respective plate PS, in such a way that the connecting pin PC inserts in the connecting hole 131 and the plate PS is housed in the respective groove 132.
The selector 1 comprises a second connecting profile 14. The second connecting profile 14 is positioned at the second end 1B of the selector 1.

The fixing element 21 is inserted inside the fixing hole 203. The fixing element 21 is movable, along the fixing direction DF between a fixing position wherein it protrudes from the bottom surface 201 to come into contact with the bottom of the groove, and a positioning position, wherein it is withdrawn, relative to the fixing position, in the direction of extraction.
It should be noted that if the striker body 10 comprises two fixing holes 203A, 203B, the striker unit 2 correspondingly includes two fixing elements 21, each inserted inside a respective fixing hole 203A, 203B.
According to an embodiment, the second shoulder tooth 3 comprises a first face 31.
The first face 31 is at least partly perpendicular to the normal direction N and facing the direction of extraction VE. The second face 31 rises starting from the second side wall 206 at a distance from the bottom surface 201, along the normal direction N, equal to a first operating distance.
According to an embodiment, the first face 31 comprises a plurality of connected elements (defining, in cross section, a broken line). This embodiment is explained in more detail below.
According to an embodiment, the second shoulder tooth 3 comprises a tip face 32. The tip face 32 is at least partly perpendicular to the transversal direction T. The tip face 32 is joined to the first face 31 in a connector R.
Said connector R is spaced from the bottom surface 201, along the normal direction N, by a second operating distance, less than the first operating distance D1.
According to an example embodiment illustrated in the drawings, the second shoulder tooth 3 (that is, the first face 31) comprises a transversal contact face 311. The transversal contact face 311 is, according to an embodiment, at least partly perpendicular to the transversal direction T and joined to the first face 31 or to the first side wall 206.
According to an embodiment, the second shoulder tooth 3 comprises a normal contact face 312. The normal contact face 312 is at least partly perpendicular to the normal direction N. The normal contact face 312 is joined to the tip face 32. The normal contact face 312 is connected to the transversal contact face 311.
According to an embodiment, the transversal contact face 311 receives in contact a portion of the second gripping tooth of the profile whilst the normal contact face 312 comes into contact with the second shoulder surface.
Preferably, the transversal contact face 311 is inclined relative to a plane perpendicular to the transversal direction T. In particular, it is inclined in such a way as to diverge in the normal direction N towards the bottom surface 201. This creates a wedge effect.
According to an embodiment, the normal contact face 312 is spaced from the bottom surface 201 by a third operating distance. The ratio between the third operating distance and the first operating distance is between 0.9 and 0.2.
According to an embodiment, the striker body 20 comprises an anti-slip tooth 207. The anti-slip tooth 207 rises from the bottom surface 201. The anti-slip tooth 207 is positioned, on the bottom surface 201, at a transversal end proximal to the first shoulder tooth 2051. Moreover, the anti-slip tooth 207 has a decreasing cross-section with the increase of the distance from the bottom surface 201.
According to an aspect of the invention, which can be combined in an indiscriminate manner with the others described above, the striker unit 2 comprises an elastic element.
The elastic element 4 is positioned at the second side wall 206. The elastic element 4 faces outside the striker body 20.
The elastic element 4 is movable between an expanded position and a compressed position, in which it is configured to apply a gripping force along the transversal direction T, in a direction coming out from the striker body 20 to keep the striker unit 2 gripping on the groove of the profile.
In more detail, the elastic element 4 protrudes, along the transversal direction T, from the second side wall 206.
It should be noted that, due to how the second shoulder tooth 3 is shaped, the side wall forms a transversal contact face 32, which is at least partly perpendicular to the transversal direction T. Said transversal contact face 32' is positioned, along the normal direction N, between the tip face 31 and the contact surface 202.
Said transversal contact face 32 is configured to come into contact (or in any case face) towards the second gripping tooth of the profile.
The elastic element 4 protrudes, along the transversal direction T, at the transversal contact face. Preferably, the elastic element 4 extends, along the normal direction N, from the bottom surface 201 to a position above the second shoulder tooth 3.
This allows the elastic element 4 to deform due to the thrust which the second gripping tooth exerts on it.
Preferably, the elastic element 4 comprises a bending spring, configured to generate the gripping force in response to a bending of the bending spring. The elastic element 4 may also comprise a leaf spring.
Described in this way, it should be noted that with the selection mechanism 100 according to the invention it is possible to implement a method for reconfiguring the door or window, varying it between a first and a second actuating configuration, CA1, CA2.
The above-mentioned embodiments differ in terms of the type of movement which the operating element, that is to say, the handle, must perform in order to move the door or window to the tilted opening configuration.
More in detail, these actuation configurations can correspond to a positioning suitable for actuation with the right hand or with the left hand, as well as a movement of the handle upwards or downwards.
According to the first configuration CA1, the first connecting profile 13 is connected to the connecting pin PC of the plate PS of the drive unit GR and the second connecting profile 14 is connected, if necessary to a rod.
According to the second configuration CA2, the second connecting profile 14 is connected to the connecting pin PC of the plate PS of the drive unit GR and the first connecting profile 13 is connected, if necessary to the rod.
For this reason, the reconfiguration method comprises a step of rotating the selector 1, about an axis parallel to the normal direction N, for connecting the first connecting profile 13 or the second connecting profile 14 to the connecting pin PC of the plate PS, in this way switching the operating kit between the first and the second actuating configurations CA1, CA2.
It should be noted that if the selector 1 is of the type with a plurality of connecting holes 133, 143, the method comprises a step of translation along the longitudinal direction L, for removing the connecting pin PC from a connecting hole 133 of said plurality 133 and inserting it in another connecting hole 133 of said plurality spaced from the previous hole along the longitudinal direction.
According to an aspect of the invention, the invention provides a stroke control mechanism for controlling the end of stroke of a CRS slider of the operating kit.
The slider CRS is connected to the operating element in such a way that a relative movement, that is, rotation, results in a corresponding movement of the slider CRS along the longitudinal direction L.
The slider CRS comprises an end of stroke surface SFC, which is perpendicular to the longitudinal direction L and which is configured to enter into contact with a contact object which defines the end of the stroke of the slider CRS. Said contact object is defined by the tilting (or contact) pin 11 of the selector 1.
The stroke control mechanism comprises a selector 1 according to any one of the features described in the invention. More specifically, the selector 1 which is suitable (also or at least) for the stroke control mechanism comprises a first stop surface 113A and a second stop surface 113B, perpendicular to the longitudinal direction L. The first and second stop surfaces 113A, 113B are surfaces oriented towards the longitudinal direction L defined by the tilting pin 11 (or, more generally, contact pin 11). The first and second stop surfaces 113A, 113B are configured to make contact with the end of stroke surface SFC.
Also in this case, the selector 1 can be connected to the operating kit by means of the first connecting profile 13 or the second connecting profile 14, in an interchangeable fashion. Thus, depending on how the selector 1 is connected to the operating kit, the tilting pin 11 varies its distance from the slider CSR between a first distance, corresponding to a first actuating configuration, and a second distance, corresponding to a second actuating configuration. This varies, in effect, the maximum stroke which the operating element can perform. Since the first distance is greater than the second distance, in the second embodiment the operating element has a smaller stroke.
In this way, by varying the position of the selector 1 along the longitudinal direction L (by inversion by 180 degrees about the normal direction or the longitudinal translation) it is possible to allow the reconfiguration of the door or window with a same part.
Not only that, since the tilting pin 11 has both the top surface 111A and the first and the second stop walls 113A, 133B with a standardised piece, it is possible to make the selector for the selection mechanism and the end of stroke for the stroke control mechanism, with full advantage of the standardisation of the pieces relative to their function and their actuation configuration.
