TECHNICAL FIELD
[0001] The present invention relates to an accessory for tilting and turning a door or window.
[0002] The present invention also relates to an opening and closing system for tilting and turning a door or window. BACKGROUND
[0003] Opening and closing systems for doors or windows that allow the sash to be opened alternately in a turning or tilting mode, and closed by being constrained to the fixed frame, are already known.
[0004] Typically, such opening and closing systems comprise a cylindrical hinge by means of which a column of the sash is connected in a rotatable manner to a corresponding column of the fixed frame about a first substantially vertical axis, allowing the turning opening of the sash.
[0005] Such a hinge is configured to also allow the tilting opening of the sash by rotating it about a second substantially horizontal axis defined at a transverse piece, typically the lower transverse piece, of the sash.
[0006] This second rotation axis is defined by a lower cylindrical hinge, the pin of which is integral with the sash, which has the possibility of tilting with respect to the fixed frame, and by a closing element of the sash, typically comprising a tip or the like and arranged at a column of the sash opposite the column hinged to the fixed frame, or at the lower transverse piece of the sash, which has the possibility of tilting with respect to the fixed frame.
[0007] In the case of tilting opening, the upper transverse piece of the sash moves away from the fixed frame. Therefore, the known systems comprise an accessory adapted to support the sash at its upper transverse piece in the tilted position, limiting the tilting angle thereof with respect to the fixed frame.
[0008] This accessory, known in the jargon of the sector as "arm" or "scissors", typically comprises:
[0009] - a guide body configured to be fixed to the upper transverse piece of the sash;
[0010] - a sliding element, typically comprising a rod, which can slide along the upper transverse piece of the sash with respect to (and typically below) the guide body, and is provided with a connecting element for connection with a manoeuvring device adapted to move the sliding element in a sliding manner along the upper transverse piece, and the manoeuvring device is mounted on the sash and can be operated by a control member, for example a handle or a knob;
[0011] - a connecting arm having a first end portion, which is coupled by a rotational translation movement to the guide body, and a second end portion configured to be connected to the movable portion of the upper tubular hinge, by which the sash is coupled to the fixed frame (the upper hinge is mounted on the fixed frame and the movable part of the upper hinge is coupled to the sash by the connecting arm);
[0012] - at least one catch, which is coupled to the connecting arm and which protrudes from a face of the catch facing the slider;
[0013] - a selector member, which is coupled to the slider in a sliding manner integral with the slider and which is configured to engage and disengage the catch according to a predefined sequence of engagement and disengagement positions corresponding to the closed position, the tilted position and the turned position of the sash, after the sliding of the slider.
[0014] The operating device is generally of the cam lever type and also comprises and operates a closing element (tip, catch, locking bolt, etc.) adapted to constrain the sash in the closed position on the fixed frame after being engaged in a respective striker fixed or obtained in the fixed frame itself.
[0015] The control member generally comprises a handle which can be rotated between three different positions, which can be reached by a continuous rotation of about 90° and which correspond respectively to the closed position, the turned position and the tilted position of the sash, with respect to an axis of rotation orthogonal to the plane of the sash.
[0016] The selector member comprises at least one striker configured to engage and disengage the catch after the sliding of the slider integral with the selector member.
[0017] When the catch is engaged in the striker, the connecting arm is completely constrained to the upper crosspiece of the sash, since any movement with respect to the upper crosspiece is prevented. Therefore, the sash can be operated in the closed position or in the turned position, while the tilted opening is prevented.
[0018] On the contrary, when the catch is disengaged from the striker, the connecting arm is constrained to the upper crosspiece of the sash only by means of its first end portion, which is coupled to the guide body and therefore to the upper crosspiece of the sash by a rotational translation movement. On the contrary, the second end portion of the connecting arm is fixed to the movable portion of the upper hinge mounted on the frame. Therefore, the sash can be operated in the tilted position according to the maximum opening angle.
[0019] According to the position of the control element (handle), two different sequences of operation of the sash are required on the market, i.e. the so-called "standard" sequence and the "logical" sequence.
[0020] The "standard" sequence provides three successive positions of the control element, which can be reached in succession by rotating by about 90°, in correspondence with the closed position, the swivel position and the tilt position of the sash, in the reverse order as well.
[0021] In this case, the selector member must be provided with a striker which engages the catch throughout the sliding travel of the slider corresponding to the rotation of the handle between the closed position, in which the handle is aligned substantially parallel to the post of the sash and faces downwards, and the swivel position, by about 90°, disengaging from the striker only in the subsequent travel of the slider corresponding to the rotation of the handle between the swivel position, in which the handle is aligned substantially parallel to the crosspiece of the sash, and the tilt position, in which the handle is aligned substantially parallel to the post of the sash and faces upwards, by about 90°, and vice versa.
[0022] The "standard" sequence provides three successive positions of the control element, which can be reached in succession by rotating by about 90°, in correspondence with the closed position, the swivel position and the tilt position of the sash, in the reverse order as well.
[0023] In this case, the selector member must be provided with a striker which engages the catch throughout the sliding travel of the slider corresponding to the rotation of the handle between the closed position, in which the handle is aligned substantially parallel to the post of the sash and faces downwards, and the swivel position, by about 90°, disengaging from the striker only in the subsequent travel of the slider corresponding to the rotation of the handle between the swivel position, in which the handle is aligned substantially parallel to the crosspiece of the sash, and the tilt position, in which the handle is aligned substantially parallel to the post of the sash and faces upwards, by about 90°, and vice versa.
[0024] To implement these two different handling sequences, it is known that the accessory ("arm") has been differently configured at the production stage, provided with differently configured selector members or with different connecting arms having two catches fixed at different distances from each other.
[0025] This solution requires the production of a plurality of different components (selector members and / or connecting arms) and the arrangement of different kits according to the "standard" sequence or the "logical" sequence to set different accessories for tilt and swivel opening, with consequent complexity in production and warehousing, which leads to an increase in costs.
[0026] To overcome such problems, EP3274534B1 proposes to provide the connecting arm with two catches, wherein a first catch is coupled to the connecting arm in a fixed position and a second catch is removably coupled to the connecting arm in one of two possible positions having a different distance with respect to the first catch. The two possible positions of the second catch are defined by two through holes made in the connecting arm and a portion of the second catch can be inserted into each of the two through holes. The second catch is then made integral with the connecting arm by means of a screw which is screwed in a threaded hole made in the second catch and the head of which rests in a seat made on the face of the connecting arm opposite to the face from which the second catch protrudes. A pair of elastic wings keep the second catch anchored to the hole to which it is to be fixed, facilitating the operations of screwing and unscrewing the screw.
[0027] This solution allows to configure the same accessory according to the opening sequence desired by the final installer.
[0028] However, this solution must provide a pair of catches and obtain three holes in the connecting arm at a calibrated distance from each other, respectively for fixing the first catch in one of the two possible intended positions and for removably connecting the second catch in one of the two possible intended positions, thereby generating production and warehousing costs. Moreover, here the second catch is constrained to the connecting arm by the final installer by screwing and unscrewing the respective retaining screw therein. In addition to complicating the installation operations, this threaded connection can loosen in use, causing malfunction problems. SUMMARY

[0043] With reference to the attached drawings, reference number 10 generally indicates an accessory for tilting and turning a door or window.
[0044] The accessory 10 is part of an opening and closing system for tilting and turning a door or window, in which a sash 100 is coupled in a rotatable manner to a fixed frame (not shown) about an axis of articulation A-A by means of articulation joints 102 (only partially depicted), which are generally a pair of cylindrical articulation joints that join a column of the sash 100 to a corresponding column of the fixed frame, with one upper cylindrical articulation joint and one lower cylindrical articulation joint.
[0045] The system then comprises a manoeuvring device 103 which can be operated by means of a control element 104 and is adapted to move the movable part of the closing element which constrains the sash 100 to the fixed frame in the closed position of the door or window by means of the control element.
[0046] The closing element can comprise a tip and / or a pawl and / or a locking bolt which is fixed to a rod mounted axially slidingly along a peripheral portion of the sash 100 and is adapted to engage in a corresponding impact seat fixed or formed along a peripheral portion of the fixed frame.
[0047] The hinge 102 and the closing element are configured so as to allow the sash 100 to be opened both in a rotation mode, i.e. by rotating about the axis of articulation A-A, and in an inclination mode, i.e. rotating about an axis parallel to the transverse piece of the sash 100 and generally defined at the lower transverse piece of the sash 100.
[0048] The hinge 102 and the closing element, being of the type known to the person skilled in the art, are not described and depicted in detail.
[0049] Preferably, both the sash 100 and the fixed frame comprise a peripheral profile along which there is a passage which accommodates the components of the opening and closing system. The drawings show a section of a possible peripheral profile 110 of the sash 100 which has, at the arch extrados, a passage 111 in which a rod is axially slidingly accommodated for the transmission and resetting of the movement actuated by the manoeuvring device 103 after the control given by means of the control element 104. Such a rod is coupled both to the closing element (pawl, tip, locking bolt) and to the movable part of the accessory 10.
[0050] Generally, the manoeuvring device 103 is mounted on the column of the sash 100 opposite the column which is coupled to the fixed frame.
[0051] The control element 104 allows the operation of the manoeuvring device 103 to be controlled from the outside; for example, the control element 104 comprises a handle which can be rotatably mounted on the sash 100 about an axis of rotation B-B orthogonal to the plane of the sash 100.
[0052] The manoeuvring device 103, the control element 104 and the transmission and resetting rod are not described and depicted in detail, being of the type known to the person skilled in the art.
[0053] Preferably, the control element 104 can be rotated about the axis of rotation B-B through a total angle substantially equal to 180°, so as to be able to assume, after a continuous rotation of about 90° in either direction of rotation, three operating positions corresponding to three operating positions of the opening and closing system and, as will be seen, of the accessory 10, according to a predefinable sequence.
[0054] With reference to the exemplary embodiments, the control element 104 can assume:
[0055] - a first operating position (P1) Figure 4 and Figure 8 corresponding to a closed position of the leaf 100 on the fixed frame, i.e. a position in which the leaf is in the closed position of the door or window and is constrained to the fixed frame by the closing element being engaged in the corresponding impact seat; in the case in which the control element 104 comprises a handle, the handle is generally aligned with the corresponding post of the leaf 100 and faces downwards.
[0056] - a second operating position (P2) Figure 5 and Figure 9 which can be reached after a rotation of about 90° in the counterclockwise direction starting from the first operating position and corresponds to an open position of the leaf 100 with respect to the fixed frame, i.e. a position in which the closing element is disengaged from the corresponding impact seat and the leaf 100 can be moved away from the fixed frame to open the door or window; in the case in which the control element 104 comprises a handle, the handle is aligned substantially parallel to the crosspiece of the leaf 100.
[0057] - a third operating position (P3) Figure 6 and Figure 10 which can be reached after a rotation of about 90° in the counterclockwise direction starting from the second operating position and corresponds to an open position of the leaf 100 with respect to the fixed frame, i.e. a position in which the closing element is disengaged from the corresponding impact seat and the leaf 100 can be moved away from the fixed frame to open the door or window; in the case in which the control element 104 comprises a handle, the handle is generally aligned with the corresponding post of the leaf 100 and faces upwards.
[0058] Depending on how the attachment 10 is configured, the second operating position and the third operating position can correspond respectively to a swivel position and to a tilt position (standard order, Figure 5 and Figure 6 ) or vice versa (logical order, Figure 9 and Figure 10 ).
[0059] The attachment 10 comprises a guide body 11 configured to be fixed to one side of the leaf 100; preferably to the upper crosspiece of the leaf 100 and advantageously to the channel 111.
[0060] The guide body 11 can be fixed to the channel 111 by means of a threaded element of the granular type 12 or the like.
[0061] The accessory 10 comprises then a slide 13 which can slide with respect to the guide body 11 along a sliding direction D-D, the slide 13 extending, in use, parallel to the longitudinal development of the side of the sash 100 on which the guide body 11 is fixed, and comprising, in the example depicted, the upper crosspiece of the sash 100.
[0062] The slide 13 is provided with a connection member 14 which is connected with a command device 103 suitable to move the slide 13 in a sliding manner along the sliding direction D-D.
[0063] The slide 13 advantageously has the shape of a flat bar and is configured to be housed in a channel 111, generally located below the guide body 11.
[0064] The connection member 14 can comprise a projection and / or a hole through which the slide 13 can be connected to the command device 103 by means of a transmission and return lever (not depicted).
[0065] The accessory 10 comprises then a connection arm 15 configured to connect the guide body 11 to a joining hinge 102 through which the sash 100 can be coupled to the fixed frame; generally, through an upper joining hinge 102 to the fixed frame.
[0066] The connection arm 15 has:
[0067] - a first end 15a which is joined to the guide body 11 by a rotational translation movement, said first end 15a can slide along a direction having a component substantially parallel to the sliding direction D-D and can rotate about an axis of rotation C-C substantially orthogonal to the sliding direction D-D;
[0068] - a second end 15b configured to be connected to the movable part of the (upper) joining hinge 102.
[0069] The first end 15a can rotate about a pin 16 defining the axis of rotation C-C and is housed in a slidable manner along a slot 17 formed in the guide body 11 and extending parallel to the sliding direction D-D.
[0070] The second end 15b has, for example, an angled portion which can be fixed, for example by means of a granular element 18 or the like, to the movable part of the joining hinge 102.
[0071] The accessory 10 comprises then at least one catch 19 coupled to the connection arm 15 in a defined position between the first end 15a and the second end 15b of the connection arm 15. The catch 19 projects from a face of the connection arm 15 facing the slide 13.
[0072] Preferably, the coupling position of the catch 19 along the axial development of the connecting arm 15 is fixed. Such position is for example uniquely defined by a single through hole 20. The catch 19 can be coupled to the connecting arm 15 by a rigid, integral and advantageously permanent connection, such as for example by riveting, or by a partial and adjustable connection configured to allow the rotation of the catch 19 about its longitudinal axis and / or the translation of the catch 19 along its longitudinal axis, for example in the case where the catch 19 is configured to allow a "pressure" adjustment.
[0073] The catch 19 can comprise a pin or peg with an enlarged and / or cammed (eccentric) head.
[0074] As will become clear in the following, the accessory 10 can also comprise only a single catch 19, the accessory 10 still being configured to carry out a "standard" opening sequence or a "logical" opening sequence without changing the position of the catch 19 along the axial development of the connecting arm 15.
[0075] Preferably, the accessory 10 can comprise a connecting rod 21 which, at opposite ends, is joined to the guide body 13 and to the connecting arm 15, respectively, by means of respective engagement pins 22, 23.
[0076] The accessory 10 then comprises a selector member 24 which is coupled to the slider 13 in a manner that slides integrally with the slider 13 and is configured to engage and disengage the catch 19 according to a predefinable sequence of engagement and disengagement positions corresponding to the closed, inclined and rotated positions of the sash 100 with respect to the fixed frame, after the sliding of the slider 13 itself.
[0077] According to the present application, the selector member 24 comprises:
[0078] at least one base body 25 which is coupled to the slider 13 in a manner that slides integrally with the slider 13, and
[0079] at least one insertion body 26 which is reversibly coupled to the base body 25 between a first position and a second position corresponding to a "logical" opening sequence and a "conventional" opening sequence, respectively.
[0080] The base body 25 has, near its first end, at least one first engagement seat 27 for engagement with the catch 19, so as to constrain the connecting arm 15 to the slider 13 in a first engagement position corresponding to the closed position of the sash 100 on the fixed frame.
[0081] The insertion body 26 has, arranged adjacent to each other:
[0082] - at least one second engagement seat 28 for engagement with the catch 19 so as to constrain the connecting arm 15 to the slider 13 in a second engagement position corresponding to a tilted position of the leaf 100 with respect to the fixed frame, and
[0083] - a recess 29 defining a free disengagement zone of the catch 19 so as to release the connecting arm 15 from the slider 13 in a disengagement position corresponding to a rotated position of the leaf 100 with respect to the fixed frame.
[0084] The insertion body 26 is reversibly coupled to the base body 25 between:
[0085] - a first position in which the recess 29 is adjacent to the first engagement seat 27; therefore, in this case, the first engagement seat 27, the recess 29 and the second engagement seat 28 are arranged in sequence with respect to each other;
[0086] - a second position in which the second engagement seat 28 is adjacent to the first engagement seat 27; therefore, in this case, the first engagement seat 27, the second engagement seat 28 and the recess 29 are arranged in sequence with respect to each other.
[0087] Therefore, in the first position of the insertion body 26, the recess 29 is interposed between the first engagement seat 27 and the second engagement seat 28.
[0088] In the first position of the insertion body 26, the first engagement position, the disengagement position and the second engagement position of the catch 19 follow each other following the sliding of the slider 13 operated by the handling device 103, in turn operated by means of the control element 104. In this case, according to a "logical" opening sequence, the three different consecutive positions of the control element 104 correspond to the closed position, the tilted position and the rotated position of the leaf 100, respectively.
[0089] This is clearly shown in Figure 8 , Figure 9 and Figure 10 , Figure 8 , Figure 9 and Figure 10 show the insertion body 26 coupled to the base body 25 in the first position:
[0090] - Figure 8The accessory 10 is shown in the closed position of the leaf 100. The catch 19 is engaged in the first engagement seat 27, thereby constraining the connecting arm 15 to the slider 13. The connecting arm 15 is thus constrained in a rigid, integral and temporary manner to the assembly comprising the guide body 11 and the slider 13. That is, any movement of the connecting arm 15 with respect to the guide body 11 is prevented. The control element 104 is in its first position. The closing element - not shown and which, as will be seen, can also comprise a further auxiliary catch 30 coupled to the connecting arm 15 - is engaged in the corresponding impact seat and / or engagement seat on the fixed frame. The leaf 100 is thus constrained to the fixed frame in the closed position.
[0091] - Figure 9 The accessory 10 is shown in the tilted position of the leaf 100. After the control element 104 has been rotated in the counterclockwise direction by about 90°, the control element 104 reaches its second position. The slider 13 has thus moved in a sliding motion along the channel 111, through a corresponding stroke (from left to right in the figure), thereby bringing the recess 29 to the catch 19. The catch 19 is thus disengaged from the slider 13, and therefore the connecting arm 15 is released from the slider 13. The second end 15b of the connecting arm 15 can thus rotate about the hinging axis A-A, while its first end 15a can perform a rotational translation motion with respect to the guide body 11; this allows the upper crosspiece of the leaf 100 to move away from the fixed frame after the leaf 100 itself has been rotated / tipped about a rotation axis defined at the lower crosspiece of the leaf 100, parallel to the lower crosspiece, and generally identified by the components of the lower hinging joint and the closing element (e.g. the tip), identification being made in a manner known per se and therefore not described or shown. The closing element - including the possible further auxiliary catch 30 - is disengaged from the corresponding impact seat and / or engagement seat. The leaf 100 is thus in the tilted position, held at its upper crosspiece by the connecting arm 15, which limits the opening angle thereof.
[0092] - Figure 10 The accessory 10 is shown in the rotated position of the leaf 100. After the control element 104 has been further rotated in the counterclockwise direction by about 90°, the control element 104 reaches its third position. This manoeuvre is performed with the leaf 100 resting in a position corresponding to the closed position, close to the fixed frame. The slider 13 has thus moved in a sliding manner along the channel 111, through a corresponding further stroke (from left to right in the figure), thereby bringing the second engagement seat 28 to the catch 19. The catch 19 is thus constrained to the slider 13, and therefore the connecting arm 15 is constrained to the slider 13. As will be seen, the connecting arm 15 is thus in a position corresponding to the open position of the leaf 100. Figure 8As shown in the case in Figure 9 , the connecting arm 15 is thus constrained in a rigid, integral and temporary manner to the assembly comprising the guide body 11 and the slider 13. That is, any movement of the connecting arm 15 with respect to the guide body 11 is prevented. Conversely, as in ,
[0093] As known and apparent, the manoeuvring for moving the control element 104 and therefore the manoeuvring device 103 and the movable components operated thereby (transmission and return levers, closing element and slider 13) is performed with the sash 100 resting in the closed position close to the fixed frame.
[0094] Conversely, in the second position of the insertion body 26, the second engagement seat 28 is interposed between the first engagement seat 27 and the recess 29.
[0095] Therefore, in the second position of the insertion body 26, the first engagement position, the second engagement position and the disengagement position of the catch 19 follow one another following the sliding of the slider 13 operated by the manoeuvring device 103, in turn operated by means of the control element 104. In this case, according to the "conventional" opening sequence, the three different consecutive positions of the control element 104 correspond respectively to the closed position, the rotated position and the tilted position of the sash 100.
[0096] This is clearly shown in Figure 4 , Figure 5 and Figure 6 , Figure 4 , Figure 5 and Figure 6 show the insertion body 26 coupled to the base body 25 in the second position:
[0097] - Figure 4 show the accessory 10 in the closed position of the sash 100, as in the case shown in Figure 8 , the catch 19 is engaged in the first engagement seat 27.
[0098] - Figure 5 show the accessory 10 in the rotated position of the sash 100, as in the case shown in Figure 10 , the catch 19 is engaged in the second engagement seat 28.
[0099] - Figure 6 show the accessory 10 in the tilted position of the sash 100, as in the case shown in Figure 9 , the catch 19 is arranged in the free zone defined by the recess 29.
[0100] It can be noted that, in this case, by reversing the position of the insertion body 26, the order in which the second engagement portion 28 and the recess 29 follow the first engagement portion 27 is reversed compared to the previous case. Therefore, in the operating sequence operated by the operating device 103, after control (rotation) is given to the control element 104, the tilt position and the rotation position follow each other in reverse order. In this case ( Figure 4 , Figure 5 and Figure 6 In fact, from the closed position ( Figure 4 Starting from the beginning, rotate to the desired position. Figure 5 ) and then tilt position ( Figure 6 They followed each other.
[0101] Note that the change in the order of the closed position, tilt position, and rotation position following each other to form a "standard" or "logical" sequence is achieved only by modifying (reversing) the position of the insertion body 26. The latch 19 remains the same and is held in a fixed position along the axial extension of the connecting arm 15.
[0102] Advantageously, this operation is made easier and faster by connecting the insertion body 26 to the base body 25 with a connector, which is preferably a removable connector of the type of convex / concave connector, interlocking connector, snap-fit connector, shape connector or similar connector.
[0103] Even more advantageously, such a connector is formed by at least one convex protrusion 31, which is formed in one of the insertion body 26 and the base body 25, and can be inserted into at least one corresponding concave housing 32 formed in the other of the insertion body 26 and the base body 25.
[0104] In the illustrated embodiment, the base body 25 includes a pair of protrusions 31 that are removably inserted into a corresponding concave housing 32 (opening) obtained in the insertion body 26.
[0105] Advantageously, the base body 25 includes a connecting portion 250 along its longitudinal extension that connects to the insertion body 26. This connecting portion 250 is adjacent to the first engagement seat portion 27. In the illustrated embodiment, this connecting portion 250 has a strip shape and forms a pair of protrusions 31 thereon.
[0106] In a preferred embodiment, the base body 25 includes a third engagement portion 33 for assisting the locking 30 near a second end axially opposite to its first end. Advantageously, if present, the connecting portion 250 extends longitudinally between the first engagement portion 27 and the third engagement portion 33.
[0107] The auxiliary lock catch 30 is coupled to the connecting arm 15 at a defined position between the lock catch 19 and the second end portion 15b of the connecting arm 15. The second lock catch 30 projects from the face of the connecting arm 15 facing the slider 13. The auxiliary lock catch 30 can comprise a peg or a pin and can have an enlarged and / or shaped head, for example a cam-shaped head. If present, the auxiliary lock catch 30 is preferably coupled to the connecting arm 15 by means of an adjustable connection configured to allow rotation of the auxiliary lock catch 30 about its longitudinal axis and / or translation of the auxiliary lock catch 30 along its longitudinal axis, for example allowing a "pressure" adjustment. However, even in this case, the position of the auxiliary lock catch 30 along the axial development of the connecting arm 15 is fixed and not modified as the configuration of the accessory 10 is changed to carry out a "standard" manoeuvre sequence or a "logical" manoeuvre sequence.
[0108] If present, the auxiliary lock catch 30 is advantageously coupled to the connecting arm 15 in an adjustable manner, while the lock catch 19 is not. The auxiliary lock catch 30 forms an auxiliary closing point and can be omitted.
[0109] As is clear from the figures, the auxiliary lock catch 30 engages in the respective third engagement seat 33 only when the accessory 10 is moved to the closed position of the sash 100 ( Figure 4 and Figure 8 ) and is disengaged from the third engagement seat 33 both in the tilted position and in the rotated position, regardless of the order in which they follow one another ( Figure 5 and Figure 6 and Figure 9 and Figure 10 ).
[0110] That is, the third engagement seat 33 is arranged to engage with the auxiliary lock catch 30 when the lock catch 19 is engaged in the first engagement seat 27 and to disengage from the auxiliary lock catch 30 when the lock catch 19 is engaged in the second engagement seat 28 and / or is disengaged at the free zone defined by the recess 29.
[0111] The base body 25 then comprises a connection member 34 with the slider 13, which can for example comprise a hole in which a protrusion formed in the slider 13 and / or vice versa can be inserted and / or a recess and / or a threaded element, etc. which accommodates the corresponding portion of the slider 13.
[0112] Advantageously, the insertion body 26 comprises a flat portion 260 along the longitudinal development of which, parallel to the sliding direction D-D, the first section forming the second engagement seat 28 and the second free section defining the recess 29 follow one another.
[0113] The insertion body 26 advantageously comprises a coupling portion 261 complementary to the coupling portion 250 defined in the base body 25.
[0114] In the illustrated embodiment, the coupling portion 261 comprises an inverted U-shaped channel in which the strip-shaped coupling portion 250 is housed, and the "bottom" of which comprises the flat portion 260. Advantageously, the hole 32 is formed at the flat portion 260.
[0115] Each of the first and second engagement seats 27, 28 comprises a pair of facing and substantially parallel side portions 270, 280 extending parallel to the sliding direction D-D, which delimit a longitudinal recess in which the catch 19 can be inserted by sliding.
[0116] Preferably, the side portions 270, 280 have respective fins 271, 281 at the top, which delimit a slit narrower than the recess delimited thereby. In this case, advantageously, the catch 19 has an enlarged head arranged below such fins 271, 281.
[0117] At the recess 29, the flat portion 260 is devoid of side portions or lateral walls or the like, so as to leave the catch 19 free to slide in a plane containing the connecting arm 15, along a direction transverse to the sliding direction D-D.
[0118] The possible third engagement seat 33 comprises a pair of facing and substantially parallel side portions 330 extending parallel to the sliding direction D-D, which delimit a longitudinal recess in which the auxiliary catch 30 can be inserted by sliding.
[0119] Advantageously, the side portions 330 comprise flat walls (i.e. without fins).
[0120] The base body 25 and / or the insertion body 26 can advantageously have, along their longitudinal edges, respective longitudinal fins 251 and 262 projecting outwardly and advantageously configured to engage in the channel 111.
[0121] From the foregoing it is evident that the use of adjectives such as "first", "second", "third" and the like does not have a limiting purpose.
[0122] The subject of the present application is also an opening and closing system for tilting and rotating a door or window 100, comprising:
[0123] at least one joining hinge 102 by which the sash 100 can be coupled in a rotatable manner to the fixed frame of the door or window about a hinge axis A-A;
[0124] - an appendix 10, as described above and adapted to be mounted on a side of the sash 100;
[0125] - a manoeuvring device 103, which can be coupled to the slider 13 and move it in a sliding manner along the sliding direction D-D, and which can be operated by means of a control element 104, wherein such manoeuvring device 103 is configured to be mounted on a side of the sash 100.
[0126] Preferably, the appendix 10 is configured to be mounted on the upper crosspiece of the sash 100, and the manoeuvring device 103 is configured to be mounted on the column of the sash 100 opposite to the column hinged to the fixed frame by means of the combined hinge 102.
[0127] The subject of the present application is also a door or window having a sash 100 coupled to a fixed frame by means of an opening and closing system as described above, wherein:
[0128] - a side (typically a column) of the sash 100 can be coupled in a rotatable manner to the fixed frame about a hinging axis A-A by means of a combined hinge 102 configured to allow both tilting opening and turning opening of the sash 100 itself,
[0129] - on the side of the sash 100 opposite to the hinged side, a manoeuvring device 103 is mounted, as well as a control element 104;
[0130] - on a side of the sash 100 (typically a crosspiece, and advantageously an upper crosspiece), an appendix 10 is mounted, wherein the guide body 11 is fixed to the sash, the second end 15b of the connecting arm 15 is fixed to the movable part of the combined hinge 102, and the slider 13 is connected to a transmission and / or return rod operated by the manoeuvring device 103.
[0131] The mounting and operation of the appendix 10 according to the present application are immediately clear from the above description and from the attached drawings.
[0132] The advantage of the present application is to allow modifying the manoeuvring sequence of the sash with a single appendix, without the need to use different selector members (strikes) and / or different connecting arms, and without necessarily having to provide at least two catches, at least one of which in a fixed position on the connecting arm would require to be modified by laborious operations.
[0133] In order to modify the manoeuvring sequence of the sash (to convert it from "standard" to "logical", or vice versa), it is sufficient to invert the position of the insertion body. This advantageously occurs without the need to unscrew and re-screw any components, thus eliminating the risk of loosening of the threaded couplings and the resulting problem of malfunction.
[0134] The accessory thus conceived for tilting and rotating a door or window lends itself to numerous modifications and variants, all falling within the scope of the present application; 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.
