- the section bar 200 is also of a known type and it could also be different from the one shown in the accompanying figures.
- section bar 200 comprises a portion to which the fixed arm 101 has to be connected.
- This portion has a bottom 201 that connects to two side edges 202, 203, which extend in a respective flap 204, 205 substantially parallel to the bottom 201.

- the main body of the anchoring plate 11 has, advantageously, a length that is substantially equal to or greater than that of the portion of the fixed arm 101 that has to be anchored to the section bar 200.
- the anchoring plate 11 has L shape: an end of its main body extends in an appendage that forms together with the main body the two arms of an L.
- the anchoring plate 11 can be inserted in the channel of the two section bars 200, 200a that contribute to form an angle of the fixed frame of the window or door, where the section bar 200 forms the (upper or lower) crosspiece and the section bar 200a forms an upright.
- the anchoring plate 11 is attached in a substantially rigid manner in rotation and in translation to the fixed arm 101.
- the anchoring plate 11 is fixed with respect to the base body 101 (fixed arm).
- the anchoring plate 11 thus forms a substantially single body with the base body 101 (fixed arm).
- the anchoring plate 11 has no possibility to move, either in rotation or in translation, relative to the base body 101 (fixed arm), to which it is attached.
- the anchoring plate 11 is fastened to the fixed arm 101 through a pin 14, which is inserted in a corresponding through hole 15 drilled in the fixed arm 101 and riveted therein, and a shape or fit coupling 16 with a corresponding portion of the fixed arm 101.
- the anchoring plate 11 also has a first shaped longitudinal edge 17 and a second shaped longitudinal edge 18 opposite each other and extending along its longitudinal development.
- the first shaped longitudinal edge 17 comprises a resting surface 17a that rests against the free end of one of the two flaps 204, 205 or to one of the two side edges 202, 203.
- the first shaped longitudinal edge 17 comprises a resting surface 17a that rests against the free end of the flap 205 that forms the outer side of the section bar 200 considered in mounting configuration, i.e. the one against which the wing abuts.
- the first shaped longitudinal edge 17 then comprises a tapered portion 17b that projects beyond the resting surface 17a to be inserted below the flap 205.
- the resting surface 17a and the tapered portion 17b of the first shaped longitudinal edge 17 form a "step".
- the second shaped longitudinal edge 18 has one or more recesses 19 that receive a respective fitting body 13.
- the second shaped longitudinal edge 18 has, at said recesses 19, an abutment or fitting surface 18b for the respective fitting body 13.
- Said abutment or fitting surface 18b is, preferably, obtained in undercut.
- the anchoring plate 11 further comprises one or more threaded holes 20 in each of which is engaged a corresponding threaded member 12.
- the threaded holes 20 are drilled in the anchoring plate 11 in a through manner between its first shaped longitudinal edge 17 and its second shaped longitudinal edge 18.
- the threaded holes 20 are drilled at end portions 21 of the anchoring plate 11. Said end portions 21 are enlarged so that they extend with a segment thereof beyond the resting surface 17a of the first shaped longitudinal edge 17 at the opposite side with respect to the tapered portion 17b thereof.
- said end portions 21 emerge from the slit delimited by the flaps 204, 205, so that the threaded holes 20, or rather the operating end of the threaded members 12 inserted therein, is accessible from outside.
- the axis of the threaded holes 20 is inclined with respect to the bottom 201 by a non-zero angle, different from a right angle. As is readily apparent from the accompanying figures, the axis of the threaded holes 20 is not parallel or coaxial to any of the axes of rotation R of the fitting bodies 13. The threaded holes 20 have distinct axes, distanced from the axes of rotation R of the fitting bodies 13.
- the threaded members 12 consist of headless screws, i.e. "threaded grub screws", which have an operating axial end, whereat a seat 120 is obtained in which an operating tool 300 is engaged, and the opposite axial and free end generally conical.

- the anchoring plate 11 is then connected to the section bar 200 by "contrasting" action of the threaded members 12. Since the anchoring plate 11 is attached to the fixed arm 101 (base body), the latter is also connected to the section bar 200 by "contrasting" action of the threaded members 12.
- the threaded members 12 are distinct and separate from the fitting bodies 13. As is readily apparent from the accompanying figures, the threaded members 12 do not engage with any of the fitting bodies 13. The threaded members 12 and the fitting bodies 13 can be operated independently of each other.
- Each fitting body 13 is mounted on the fixed arm 101 so as to be able to rotate around a respective axis of rotation R, without possibility of any translation with respect to the fixed arm 101, in particular without any possibility of any sliding along the axis of rotation R.

- each fitting body 13 comprises a tang 22 that defines the axis of rotation R and that is inserted rotatably in a corresponding through hole 230 drilled in the fixed arm 101.
- the tang 22 and the through hole 230 are not threaded.
- the through holes 230 are different and distanced from the threaded holes 20 in which the threaded members 12 are engaged; the through holes 230 are obtained in the base body 101 (fixed arm) and the threaded holes 20 are drilled in the anchoring plate 11 in such a position that, considering the system 10 in mounting condition on the accessory (concealed hinge 100), the ones are not superposed on the others.
- the tang 22 has a first axial end that emerges from the surface of the fixed arm 101 opposite to the one on which the anchoring plate 11 is mounted; in said first axial end of the tang 22 a seat 23 is obtained in which an operating tool 300 is engaged.
- the tang 22 has a second axial end opposite to the first axial end thereof and which is attached or integral to a shaped plate 24.
- the tang 22 then forms a single rigid body with the respective plate 24; the tang 22 and the respective plate 24 then always rotate together as a single rigid body.
- the plate 24 comprises a first fitting projection 24a and a second fitting projection 24b that are substantially opposite to each other with respect to the axis of rotation R.
- Each fitting body 13 is rotatable around the respective axis of rotation R between at least a first position and a second position.
- each fitting body 13 is positioned so that its first fitting projection 24a and its second fitting projection 24b are substantially aligned with the longitudinal axis of the channel 206 without interfering with the anchoring plate 11 and with the section bar 200.
- the maximum length of the plate 24, the position of the axis of rotation R with respect to the anchoring plate 11 and the width of the anchoring plate 11 are dimensioned in such a way that, when the fitting bodies 13 are in said first position, they can be inserted together with the anchoring plate 11 in the channel 206 through the slit delimited by the flaps 204, 205 without interfering with them (as shown in Figures 5 and 6 ).
- each fitting body 13 is positioned in such a way that its first fitting projection 24a is fitted against the second shaped longitudinal edge 18 of the anchoring plate 11 and its second fitting projection 24b is fitted against the side edge 202 of the section bar 200 facing the second shaped longitudinal edge 18 of the anchoring plate 11.
- each fitting body 13 - or rather the respective plate 24 - has a size in length (not necessarily equal to the maximum size in length) substantially equal to the distance between the portion of the second shaped longitudinal edge 18 of the anchoring plate 11 that is facing thereto and the inner wall of the side edge 202 of the section bar 200 facing the second shaped longitudinal edge 18, so as to fill, in length, the space existing between the anchoring plate 11 and the side edge of the section bar opposite the one towards which the anchoring plate 11 is pushed by the threaded members 12.

- the first fitting projection 24a comprises at least one stop tooth 26 adapted to engage with a corresponding portion of the second shaped longitudinal edge 18 of the anchoring plate 11 to stop the rotation of the respective fitting body 13.
- the stop tooth 26 is provided at the face of the plate 24 opposite the one from which the tang 22 extends and on a portion of the edge of the first projection 24a.

Abstract
Description
- The present invention relates to a connection system for the removable connection of an accessory for windows or doors to a window or door section bar.
- In particular, the present invention relates to a connection system for the removable connection of a "concealed hinge" for windows or doors to a window or door section bar.
- Still more in particular, the present invention relates to a connection system for the removable connection of the fixed arm a "concealed hinge" for windows or doors to a section bar of the fixed frame of a window or door.
- In the sector of windows and doors, systems are known for hinging the wings of doors or windows to the fixed frame that consist of so-called "concealed hinges", i.e. hinges that, when the wings are closed, are not visible from outside the window or door. An example of such hinges is described in patent
IT1406348 - In general terms, "concealed hinges" comprise:
- a fixed arm that is attached to the section bar that forms an upper or lower crosspiece of the fixed frame,
- a movable arm that is attached to the section bar that forms an upper or lower crosspiece of the perimetral frame of the wing,
- a group of levers articulating between them the fixed arm and the movable arm, where one of said levers supports an articulating pin on which the wing is hinged.
- In these hinging systems, particularly critical is the connection of the fixed arm of the "concealed hinge" to the section bar that forms the upper or lower crosspiece of the fixed frame.
- As is immediately understandable to the person skilled in the art, when the wing is open, its weight generates a bending stress that tends to deform the articulation levers, hindering the correct opening and closing of the wing, and to compromise the holding of the connection of the fixed arm to the respective section bar (crosspiece) of the fixed frame, with consequent risks of uncouplings and breakdowns.
- Typically, the section bars used to form the fixed frame and, in particular, the crosspieces thereof have a portion with C-shaped cross section and have a bottom whose two opposite sides connect to respective side edges, the free end of which is prolonged in a respective flap that extends substantially parallel to the bottom of the section bar. The flaps delimit an access slit to the channel defined by the bottom and by the side edges.
- According to the prior art, the fixed arm of the "concealed hinges" is shaped so as to be directly inserted in the channel of the section bar to which it is connected through so-called "contrasting grub screws", screws and/or engaging plates.
- In the first case, the fixed arm has one or more threaded through holes, in each of which is engaged a corresponding threaded grub screw (i.e. headless screw) that, following screwing, engages with its free end on the bottom or on the side edge of the section bar opposite the one towards which the fixed arm itself is thrust, "in contrast".
- In the second case, the fixed arm is connected to the section bar with known self-threading screws that engage in the section bar.
- In the third case, the fixed arm is connected to the section bar by means of a plurality of engagement plates that are mounted thereon rotatably around an axis of rotation orthogonal to the bottom of the section bar and that have a width and a length respectively smaller than and greater than the width of the access slit to the channel of the section bar. The engagement plates are rotated between two positions: a first position, in which they are positioned with their width parallel to the width of the slit so as to be able to be inserted in the channel of the section bar, and a second position, in which they are positioned with their width parallel to the longitudinal development of the section bar so as to extend in length below the flaps of the section bar blocking by obstacle the detachment of the fixed arm from the section bar.
- In known systems, the engagement plates generally have symmetrical conformation with respect to the axis of rotation or at least with respect to a plane passing through the axis of rotation.
- In some known solutions, the fixed arm is connected to the respective section bar both with screws and with engagement plates.
- However, these known solutions do not always assure a stable, secure connection able to withstand the bending stresses that are generated when the wing is open, extractions, uncouplings and/or breakdowns being possible.
- In these known solutions, moreover, the fixed arm of the "concealed hinge" is directly connected to the respective section bar; for this purpose, the fixed arm must be appropriately dimensioned and shaped according to the section bar and, when fastening takes place with "contrasting grub screws", it must be machined to create corresponding threaded holes therein. Hence, for every type of "concealed hinge" it is necessary to produce different types of the entire hinging system according to the type (in particular dimensions) of section bar forming the crosspiece of the fixed frame.
- Also known is a system for connecting "concealed hinges" as described in

Figures 6 ,8 and11 ) some components of the "concealed hinge" are shown only partially, being of a known type, not binding for the purposes of the present invention. - With reference to the figures, a
connection system 10 is shown for the removable connection of an accessory for windows or doors to a window or door section bar. - Although the
connection system 10 is applicable for connecting different types of accessories for windows or doors to a section bar forming the fixed frame or the outer frame of a movable panel of a window or door, in the present description reference will be made to the case in which the accessory consists of a so-called "concealed hinge". The connectingsystem 10 is in fact particularly suitable for connecting a "concealed hinge" or rather the fixed arm of a "concealed hinge", to a section bar forming a crosspiece of the fixed frame of a window or door. - The "concealed hinge" is known in itself and it will be described in general terms for the purposes of the present description and with reference to the accompanying figures, which are provided solely by way of non-limiting example.
- For simplicity, reference will be made to the connection of a lower "concealed hinge", i.e. applied to the lower end of a wing or movable panel, the connection of the upper "concealed hinge" being wholly similar.
- Likewise, the section bars forming the fixed frame of a window or door and the window or door in its entirety are not shown and described in a detailed manner, being of a known type.
- The "concealed hinge" 100 comprises:
- a) a
fixed arm 101 to be connected to asection bar 200 that forms a crosspiece of the fixed frame of a window or door; - b) a
movable arm 102 to be connected to the corresponding crosspiece of the outer frame of a wing of a window or door; - c) a group of
levers 103 that articulate thefixed arm 101 to themovable arm 102. - One of the
levers 103 supports ahinge pin 104 around which is articulated abushing 105 fixed to themovable arm 102. - The
fixed arm 101 constitutes the base body of the accessory ("concealed hinge" 100), where said base body (in the present case, the fixed arm 101) has to be connected in a fixed, complete (i.e. without possibility of any relative translation and rotation motion) and removable manner to thesection bar 200. In the description and in the claims, then, the reference numeral "101" is used to indicate, in general, the base body of an accessory and, in particular, the fixed arm of a concealed hinge forming the accessory. Equally, the reference numeral "100" is used to indicate, in general, an accessory that can be connected to a section bar of a window or door and, in particular, a "concealed hinge". - The
section bar 200 is also of a known type and it could also be different from the one shown in the accompanying figures. - For the purposes of the present invention, in any case the
section bar 200 comprises a portion to which thefixed arm 101 has to be connected. - This portion has a
bottom 201 that connects to twoside edges respective flap bottom 201. - The free ends of the two
flaps channel 206 defined between thebottom 201 and the twoside edges - In general, then, the
section bar 200 has C-shaped or double C-shaped cross section, although different conformations are possible in which, in any case, the elements (bottom, side edges and flaps) described above can be noted. - The
connection systems 10 comprises: - an anchoring
plate 11 that is adapted to be attached to the fixed arm 101 (i.e. to the base body of the accessory consisting of the "concealed hinge") and which can be inserted in thechannel 206 through the slit delimited by theflaps plate 11 is also adapted to be attached to thesection bar 200 through threadedmembers 12 acting "in contrast"; - one or more
fitting bodies 13 that are adapted to be mounted on the fixed arm 101 (i.e. on the base body of the accessory consisting of the "concealed hinge") rotating around a respective axis of rotation R substantially orthogonal to the bottom 201 and that are shaped and arranged so as to assume at least two positions:- a) a first position, in which they do not interfere with the anchoring
plate 11 and they can be inserted, together with it, in thechannel 206 through the slit delimited by theflaps - b) a second position, in which they fit between the anchoring
plate 11 and thesection bar 200.
- a) a first position, in which they do not interfere with the anchoring
- In greater detail, the anchoring
plate 11 consists of a main body with mainly longitudinal development. The main body of the anchoringplate 11 has, advantageously, a length that is substantially equal to or greater than that of the portion of the fixedarm 101 that has to be anchored to thesection bar 200. - With reference to the accompanying figures, the anchoring
plate 11 has L shape: an end of its main body extends in an appendage that forms together with the main body the two arms of an L. - In this case, the anchoring
plate 11 can be inserted in the channel of the two section bars 200, 200a that contribute to form an angle of the fixed frame of the window or door, where thesection bar 200 forms the (upper or lower) crosspiece and thesection bar 200a forms an upright. - The anchoring
plate 11 is attached in a substantially rigid manner in rotation and in translation to the fixedarm 101. For the person skilled in the art it is immediately evident from the accompanying figures and from the present description that the anchoringplate 11 is fixed with respect to the base body 101 (fixed arm). The anchoringplate 11 thus forms a substantially single body with the base body 101 (fixed arm). The anchoringplate 11 has no possibility to move, either in rotation or in translation, relative to the base body 101 (fixed arm), to which it is attached. - In the case represented in the accompanying figures, the anchoring
plate 11 is fastened to the fixedarm 101 through apin 14, which is inserted in a corresponding throughhole 15 drilled in the fixedarm 101 and riveted therein, and a shape orfit coupling 16 with a corresponding portion of the fixedarm 101. - The anchoring
plate 11 also has a first shapedlongitudinal edge 17 and a second shapedlongitudinal edge 18 opposite each other and extending along its longitudinal development. - The first shaped
longitudinal edge 17 comprises a restingsurface 17a that rests against the free end of one of the twoflaps side edges longitudinal edge 17 comprises a restingsurface 17a that rests against the free end of theflap 205 that forms the outer side of thesection bar 200 considered in mounting configuration, i.e. the one against which the wing abuts. - The first shaped
longitudinal edge 17 then comprises a taperedportion 17b that projects beyond the restingsurface 17a to be inserted below theflap 205. - The resting
surface 17a and the taperedportion 17b of the first shapedlongitudinal edge 17 form a "step". - The second shaped
longitudinal edge 18 has one ormore recesses 19 that receive a respectivefitting body 13. - As will be clearer hereinafter, the second shaped
longitudinal edge 18 has, at saidrecesses 19, an abutment orfitting surface 18b for the respectivefitting body 13. - Said abutment or
fitting surface 18b is, preferably, obtained in undercut. - The anchoring
plate 11 further comprises one or more threadedholes 20 in each of which is engaged a corresponding threadedmember 12. - The threaded holes 20 are drilled in the anchoring
plate 11 in a through manner between its first shapedlongitudinal edge 17 and its second shapedlongitudinal edge 18. - In particular, the threaded
holes 20 are drilled atend portions 21 of the anchoringplate 11. Saidend portions 21 are enlarged so that they extend with a segment thereof beyond the restingsurface 17a of the first shapedlongitudinal edge 17 at the opposite side with respect to the taperedportion 17b thereof. When the anchoringplate 11 is inserted in thechannel 206, saidend portions 21 emerge from the slit delimited by theflaps holes 20, or rather the operating end of the threadedmembers 12 inserted therein, is accessible from outside. - The axis of the threaded
holes 20 is inclined with respect to the bottom 201 by a non-zero angle, different from a right angle. As is readily apparent from the accompanying figures, the axis of the threadedholes 20 is not parallel or coaxial to any of the axes of rotation R of thefitting bodies 13. The threaded holes 20 have distinct axes, distanced from the axes of rotation R of thefitting bodies 13. - The threaded
members 12 consist of headless screws, i.e. "threaded grub screws", which have an operating axial end, whereat aseat 120 is obtained in which anoperating tool 300 is engaged, and the opposite axial and free end generally conical. - Following screwing in the respective threaded
holes 20, the free end of the threadedmembers 12 projects beyond the second shapedlongitudinal edge 18 of the anchoringplate 11 and engages against theflap 204 and/or theside edge 202 opposite to theflap 205 or to theside edge 203 against which the first shapedlongitudinal edge 17 of the anchoringplate 11 itself rests. - The anchoring
plate 11 is then connected to thesection bar 200 by "contrasting" action of the threadedmembers 12. Since the anchoringplate 11 is attached to the fixed arm 101 (base body), the latter is also connected to thesection bar 200 by "contrasting" action of the threadedmembers 12. - The threaded
members 12 are distinct and separate from thefitting bodies 13. As is readily apparent from the accompanying figures, the threadedmembers 12 do not engage with any of thefitting bodies 13. The threadedmembers 12 and thefitting bodies 13 can be operated independently of each other. - Each
fitting body 13 is mounted on the fixedarm 101 so as to be able to rotate around a respective axis of rotation R, without possibility of any translation with respect to the fixedarm 101, in particular without any possibility of any sliding along the axis of rotation R. As is readily apparent from the accompanying figures, eachfitting body 13 is mounted on the base body 101 (fixed arm) with possibility of relative motion with respect to thebase body 101 only in rotation around the respective axis of rotation R. - With reference to the accompanying figures, each
fitting body 13 comprises atang 22 that defines the axis of rotation R and that is inserted rotatably in a corresponding throughhole 230 drilled in the fixedarm 101. As is readily apparent from the accompanying figures, thetang 22 and the throughhole 230 are not threaded. The throughholes 230 are different and distanced from the threadedholes 20 in which the threadedmembers 12 are engaged; the throughholes 230 are obtained in the base body 101 (fixed arm) and the threadedholes 20 are drilled in the anchoringplate 11 in such a position that, considering thesystem 10 in mounting condition on the accessory (concealed hinge 100), the ones are not superposed on the others. - The
tang 22 has a first axial end that emerges from the surface of the fixedarm 101 opposite to the one on which theanchoring plate 11 is mounted; in said first axial end of the tang 22 aseat 23 is obtained in which anoperating tool 300 is engaged. - The
tang 22 has a second axial end opposite to the first axial end thereof and which is attached or integral to a shapedplate 24. Thetang 22 then forms a single rigid body with therespective plate 24; thetang 22 and therespective plate 24 then always rotate together as a single rigid body. - The
plate 24 comprises a firstfitting projection 24a and a secondfitting projection 24b that are substantially opposite to each other with respect to the axis of rotation R. - Each
fitting body 13 is rotatable around the respective axis of rotation R between at least a first position and a second position. - In the first position (
Figures 2, 3 ,5, 6 and8 ), eachfitting body 13 is positioned so that its firstfitting projection 24a and its secondfitting projection 24b are substantially aligned with the longitudinal axis of thechannel 206 without interfering with the anchoringplate 11 and with thesection bar 200. - As is immediately understandable for the person skilled in the art, the maximum length of the
plate 24, the position of the axis of rotation R with respect to the anchoringplate 11 and the width of the anchoringplate 11 are dimensioned in such a way that, when thefitting bodies 13 are in said first position, they can be inserted together with the anchoringplate 11 in thechannel 206 through the slit delimited by theflaps Figures 5 and 6 ). - In the second position (
Figures 10, 10A and11 ), eachfitting body 13 is positioned in such a way that its firstfitting projection 24a is fitted against the second shapedlongitudinal edge 18 of the anchoringplate 11 and its secondfitting projection 24b is fitted against theside edge 202 of thesection bar 200 facing the second shapedlongitudinal edge 18 of the anchoringplate 11. - Advantageously, each fitting body 13 - or rather the respective plate 24 - has a size in length (not necessarily equal to the maximum size in length) substantially equal to the distance between the portion of the second shaped
longitudinal edge 18 of the anchoringplate 11 that is facing thereto and the inner wall of theside edge 202 of thesection bar 200 facing the second shapedlongitudinal edge 18, so as to fill, in length, the space existing between the anchoringplate 11 and the side edge of the section bar opposite the one towards which theanchoring plate 11 is pushed by the threadedmembers 12. - The
plate 24 is shaped as an eccentric or cam, the firstfitting projection 24a and the secondfitting projection 24b having asymmetric configuration with respect to at least one plane passing through the axis of rotation R and, considering thefitting body 13 in its second position, parallel to the longitudinal axis of thesection bar 200. - Each
fitting body 13 passes from the first position to the second position carrying out a rotation of no more than 90°. - The second
fitting projection 24b can have abevel 25 that allows fitting in channels of section bars of smaller width. - The first
fitting projection 24a comprises at least onestop tooth 26 adapted to engage with a corresponding portion of the second shapedlongitudinal edge 18 of the anchoringplate 11 to stop the rotation of the respectivefitting body 13. Thestop tooth 26 is provided at the face of theplate 24 opposite the one from which thetang 22 extends and on a portion of the edge of thefirst projection 24a. Thestop tooth 26 is provided in substantially opposite position to thesecond projection 24b with respect to the axis of rotation R. - The second
fitting projection 24b comprises one or more substantially wedge-shapedreliefs 27 and, when thefitting body 13 is in its second position, they jut under therespective flap 204 or on the bottom 201. - Preferably, the
reliefs 27 are provided at the face of theplate 24 from which thetang 22 extends so as to jut below therespective flap 204 possibly causing a plastic deformation thereof. - The assembly and mounting operations of the
connection system 10 according to the present invention are immediately understandable for the person skilled in the art in light of the above description and of the accompanying figures. - Briefly, the
connection system 10 is first of all assembled on the base body of the accessory that has to be connected to thesection bar 200, in the present case theconnection system 10 is assembled on the fixedarm 101 of the "concealed hinge" 100. - For this purpose, the anchoring
plate 11 is attached to the fixedarm 101 along the longitudinal development thereof and at the surface thereof intended to lean on theflaps plate 11 is mounted on the base body (fixed arm 101) in a fixed manner in translation and rotation with respect thereto. - Likewise, the
fitting bodies 13 are mounted on the fixedarm 101 so that theirplates 24 flank the anchoringplate 11 and, in particular, they flank second shapedlongitudinal edge 18 thereof at therecesses 19. Thefitting bodies 13 are movably mounted on the fixed arm 101 (base body) with only the ability to rotate around the respective axis of rotation R. - The assembly thus obtained, with the
fitting bodies 13 in their first position, is then mounted on the section bar 200: the anchoringplate 11 and thefitting bodies 13 are inserted laterally in thechannel 206 as shown schematically inFigure 5 . -
Figure 6 shows a section view of theconnection system 10 mounted on the fixedarm 101 and inserted in thesection bar 200, before the execution of the connecting/fixing operations. - The fixed
arm 101 bears on theflaps plate 11 is inserted in thechannel 206 with its first shapedlongitudinal edge 17 approached to theflap 205 on the inner side of the frame; thefitting bodies 13 are housed in thechannel 206 and are placed in their first position. - Subsequently, before rotating the
fitting bodies 13 so as to bring them to their second position, the anchoringplate 11 is attached "in contrast" by means of the threadedmembers 12. - As shown in
Figures 7 and 8 , with the aid of anoperating tool 300, the threadedmembers 12 are screwed in the respective threadedholes 20 until their free end engages/fits below theflap 204 and/or against theside edge 202 pushing "in contrast" the anchoringplate 11 against theflap 205 and/or theopposite side edge 203. - The anchoring
plate 11 is pushed by the threadedmembers 12 towards theside edge 203 so that thesupport surface 17a of its first shapedlongitudinal edge 17 leans against the free end of theflap 205. - The tapered
portion 17b of the first shapedlongitudinal edge 17 extends below theflap 205. - After thus fixing the anchoring
plate 11 to thesection bar 200, thefitting bodies 13 are rotated, with the aid of anoperating tool 300, so as to be brought from their first position to their second position (Figures 9 ,10 and11 ). - In this way the first
fitting portions 24a fit with corresponding surfaces of the second shapedlongitudinal edge 18 of the anchoringplate 11, while the secondfitting portions 24b fit against the inner wall of theopposite side edge 202. - Any additional rotations of the
fitting bodies 13 are prevented by the engagement of therespective stop tooth 26 on the bottom 201 and/or below/against the anchoringplate 11. - The
possible reliefs 27 jut below theflap 204, deforming it. - The fixed
arm 101 is thus connected completely and stably to thesection bar 200. - In particular, thanks to the conformation and the dimensioning of the anchoring plate and of the fitting bodies cooperating therewith, it is possible to fill in a substantially complete manner the
channel 206 or rather the distance between the free end of a flap and the opposite side edge. - In the connection position, the anchoring plate and the fitting bodies form a set that extends with substantial continuity between a flap and the opposite side edge of the channel of the section bar, behaving as a single rigid body together with the fixed
arm 101. - The connection system according to the present invention has the advantage of assuring a connection of an accessory for windows or doors to the channel of a section bar that is complete, stable and secure.
- In particular, the connection system according to the present invention has the advantage of assuring a connection of the fixed arm of a "concealed hinge" to the channel of a section bar that is complete, stable, secure and able to withstand bending stresses that are generated in use, reducing the risks of deformations, extractions and breakdowns.
- The connection system according to the present invention has the advantage of being able to be applied to accessories for windows or doors, including existing ones, without requiring particular modifications to them.
- It also allows to standardise these accessories, in particular independently of the dimensions of the section bars on which they can be mounted, adopting for their connection variously shaped and dimensioned anchoring plates and fitting bodies.
- Thus, for example, in the case of "concealed hinges", the fixed arm thereof can be standardised and, as the dimensions of the section bar vary, it is sufficient to mount thereon an appropriately shaped and dimensioned connection system according to the present invention.
- The connection system for the removable connection of an accessory for windows or doors to a window or door section bar thus conceived is susceptible to many modifications and variations, all falling within the invention; furthermore, all the details are replaceable by technically equivalent elements. In practice, the materials used, as well as the dimensions, can be of any type according to the technical requirements.
