Definitions
- the present invention relates to an alignment bracket for fixtures.
- the alignment bracket in question is principally classifiable within the sector of accessories for fixtures and frames and is used in particular for aligning two profiles of a frame for thermal break fixtures in the joining zone.
- the support frame of a fixture generally consists of several profiles which are fixed in pairs at their ends in the corners of the frame by means of suitable connecting means.
- the latter consist of L-shaped angle-pieces which are made of metal or plastic and are usually known by the name of "force-fitting brackets".
- these angle-pieces have two arms which are intended to be slidably inserted inside grooves provided in the profiles and in which one or more seats are formed for the insertion of ordinary fixing means such as screws or bolts. for example.
- Each angle-piece exerts by means of its arms a pulling force on the two profiles to be joined together so as to bring them into contact against each other.
- the angle-pieces therefore allow assembly of the various profiles in an adjacent and coplanar manner so as to form the frame.
- profiles for thermal break fixtures are formed, in fact, by a main portion, which forms the part supporting the profile and intended to be directed outwards, and by a secondary portion, which is connected to the main portion by means of a thickness of heat-insulating material and which forms the part of the fixture intended to be directed inwards.
- the connecting angle-pieces are mounted for structural reasons in the zone where the main portions of the two profiles are joined together and, therefore, in. a position which is offset from the centre axes of the profiles. Consequently the secondary portions of the profiles are free to splay, albeit only slightly, not being directly fastened together by the angle-pieces.
- alignment brackets consist of connecting parts which are substantially similar to the abovementioned connecting angle-pieces and are usually known by the name of "alignment brackets".
- connection between these alignment brackets and the profiles is achieved by means of normal fixing means, such as screws and bolts, or, as is envisaged in the more recent solutions, by means of rotating fixing elements incorporated in the arms of the brackets. These rotating fixing elements are able to be forced against the edges of the grooves inside which the bracket is inserted so as to lock it with pressure inside the profiles.
- each of these fixing elements is able to pass from a releasing position, where the element is retracted inside the contour of the arm, leaving the bracket free to move with respect to the profile, into a locking position, where this element projects from the contour and engages by means of interference with the profile, locking the bracket in the desired position.
- Each of the two arms of the bracket has a fixing element rotatably inserted inside a circular seat formed in the said arm.
- the fixing element consists of a cylindrical body which acts as a rotating pivot inside the abovementioned circular seat and is provided at one end with a tongue projecting perpendicularly from its axis.
- This tongue which is formed as one piece with the cylindrical body, is eccentric with respect to the axis of the latter and, consequently, following a rotation of the cylindrical body, is able to pass from a releasing position, where the said tongue is retracted inside the contour of the arm and does not interfere with the profile, into a locking position, where the tongue, projecting from the contour of the arm, is forced against the profile and is able to fix rigidly the bracket to the said profile.
- the flat tongue portion which is intended to come into contact with the profile is shaped in the manner of an arc of a circumference and is provided with a series of teeth able to increase gripping thereof on the said profile.
- the alignment bracket described in the patent EP 1048816 has the drawback that the thrust exerted by the tongues on the profiles is concentrated substantially in a single point. This adversely affects the stability of engagement of the bracket with the profile and may result, in certain mechanical stress conditions, to gradual loosening of the fixing means and therefore a deviation (or misalignment) of the profiles.
- an object of the present invention is to eliminate the drawbacks of the known art mentioned above by providing an alignment bracket for fixtures which ensures more stable engagement with the profiles.
- Another object of the present invention is to provide an alignment bracket for fixtures which is operationally entirely safe and reliable.
- a further object of the present invention is to provide an alignment bracket for fixtures which is simple and inexpensive to produce.
- bracket 1 denotes the alignment bracket for fixtures according to the invention.
- This bracket 1 is intended, in particular, for the assembly of frames for thermal break fixtures, but may also be used as a force-fitting bracket during the assembly of frames for cold profile fixtures, on its own or in addition to other brackets also of the conventional type.
- Each thermal break profile is composed of a main portion, intended to form the outer surround of the fixture, and a secondary portion, intended to form the inner surround.
- the two portions are connected together by a further heat-insulating portion.
- the alignment bracket 1 according to the invention is mounted in the zone where the secondary portions of a first and a second profile I and II of a thermal break frame are joined together with the aim of aligning the two profiles and keeping them in a coplanar relationship.
- the actual structural connection between the two profiles I and II is performed along their two main portions by means of an ordinary force-fitting bracket (not shown).
- the alignment bracket 1 is associated with the two profiles at the same time as the force-fitting bracket during assembly of the frame.
- Each thermal break profile is provided with a special longitudinal groove S formed in the abovementioned inner portion. This groove extends longitudinally along the entire length of the profile I and II and is delimited by two opposite parallel edges, one of which, denoted by B2, is situated closer to the inner side of the profile than the other one denoted by B1.
- the alignment bracket according to the invention consists essentially of a joining angle-piece 2 formed by a flat plate - preferably made of aluminium alloy or possibly steel - and having two mutually perpendicular arms 3a and 3b forming an L-shaped profile.
- the two arms are intended to be inserted inside the grooves S of the first and the second profile I and II, respectively. This insertion is performed with the profiles separated by means of translatory sliding movement directed longitudinally with respect to the individual profile.
- each arm 3a and 3b is provided with suitable means 4 for ensuring fixing to the profile, which are able to lock the said arm inside the groove S and at the same time impart to the profile I and II an additional sliding movement towards the joining zone.
- the fixing means 4 comprise a pivot 5, which is rotatably inserted in each arm 3a, 3b, and a shaped body 6, which is eccentrically connected to the pivot 5 and is inserted inside a first guide seat 25, 26 formed in the arm 3a, 3b.
- the pivot 5 rotates, it causes a displacement of the shaped element 6 relative to the arm 3a or 3b.
- the shaped element 6 has an engaging portion 64 which, following the abovementioned displacement, projects more from the arm and pushes against the edge B2 of the groove S.
- the shaped body 6 is able to move between a releasing position 64, where the engaging portion 64 does not interfere with the longitudinal edge B2 so as to leave the arm 3a, 3b free to move inside the groove S, and at least one locking position, where the engaging portion 64 is instead forced against the edge B2 so as to lock the corresponding arm 3a, 3b inside the groove S and draw the profile I, II towards the joining zone with a sliding movement relative to the arm 3a, 3b itself.
- the pivot 5 and the connection between the shaped body 6 and the guide seat 25, 26 impart to the engaging portion 64 a rotary and translatory movement which is eccentric with respect to the axis of rotation Y of the pivot 5 and is substantially parallel to the edge B2 of the groove S.
- the engaging portion 64 causes the sliding movement of the profile I, II towards the joining zone in a direction substantially parallel to the edges B, B2 of the groove S. Owing to this movement the engaging portion 64 is brought so as to rest completely against the edge B2 of the groove S, thus ensuring extremely stable fixing of the bracket 1 to the profile.
- Each arm 3a and 3b of the angle-piece 2 has a first side surface 23 in contact with the edge B1 of the groove S and a second side surface 24 which faces the edge B2 and is slightly spaced from the latter owing to the presence of the engaging portion 64 of the shaped body 6.
- the two arms 3a and 3b may also not be mutually perpendicular so as to allow use of the bracket 1 according to the invention also in frames for fixtures forming angles other than right angles.
- constructionally speaking the guide seat 25, 26 mentioned above is formed by means of two inset zones formed in the two sides of the joining angle-piece 2.
- each inset zone extends from the from the second side surface 24 towards the inside of each arm 3a, 3b forming a rounded eyelet 27 substantially parallel to the centre axis X of the said arm.
- Each arm 3a, 3b has a circular through-hole 20 for receiving the pivot 5, which is formed inside the inset zone in a remote position from the eyelet 27.
- the pivot 5 consists of a main cylindrical body 50 which is inserted inside the through-hole 20 so as to rotate about the common axis of rotation Y and is provided at its two ends 5' and 5" with a first and a second cylindrical lug 51 and 52, respectively.

Abstract
Description
- The present invention relates to an alignment bracket for fixtures.
- The alignment bracket in question is principally classifiable within the sector of accessories for fixtures and frames and is used in particular for aligning two profiles of a frame for thermal break fixtures in the joining zone.
- As is known, the support frame of a fixture, be it made of metal or PVC, generally consists of several profiles which are fixed in pairs at their ends in the corners of the frame by means of suitable connecting means. The latter consist of L-shaped angle-pieces which are made of metal or plastic and are usually known by the name of "force-fitting brackets".
- In more detail, these angle-pieces have two arms which are intended to be slidably inserted inside grooves provided in the profiles and in which one or more seats are formed for the insertion of ordinary fixing means such as screws or bolts. for example. Each angle-piece exerts by means of its arms a pulling force on the two profiles to be joined together so as to bring them into contact against each other. The angle-pieces therefore allow assembly of the various profiles in an adjacent and coplanar manner so as to form the frame.
- In fixtures of the so-called "cold profile" type, the abovementioned angle-pieces perform fully their function, allowing the profiles to be aligned in a near perfect manner along the whole length of the joining zone. In the case, however, of fixtures of the so-called "thermal break" type, these angle-pieces do not always manage to prevent the profiles from splaying slightly in the joining zone. This is due essentially to the fact that the profiles used to form thermal break frames have a cross-section greater than that of the profiles used for cold profile fixtures. These profiles for thermal break fixtures are formed, in fact, by a main portion, which forms the part supporting the profile and intended to be directed outwards, and by a secondary portion, which is connected to the main portion by means of a thickness of heat-insulating material and which forms the part of the fixture intended to be directed inwards. The connecting angle-pieces are mounted for structural reasons in the zone where the main portions of the two profiles are joined together and, therefore, in. a position which is offset from the centre axes of the profiles. Consequently the secondary portions of the profiles are free to splay, albeit only slightly, not being directly fastened together by the angle-pieces.
- Traditionally, this problem has been solved by inserting suitable alignment means in the joining zone of the two abovementioned secondary portions of the profiles. These alignment means consist of connecting parts which are substantially similar to the abovementioned connecting angle-pieces and are usually known by the name of "alignment brackets". In this case also, the connection between these alignment brackets and the profiles is achieved by means of normal fixing means, such as screws and bolts, or, as is envisaged in the more recent solutions, by means of rotating fixing elements incorporated in the arms of the brackets. These rotating fixing elements are able to be forced against the edges of the grooves inside which the bracket is inserted so as to lock it with pressure inside the profiles.
- In greater detail, each of these fixing elements is able to pass from a releasing position, where the element is retracted inside the contour of the arm, leaving the bracket free to move with respect to the profile, into a locking position, where this element projects from the contour and engages by means of interference with the profile, locking the bracket in the desired position.
- A constructional solution of the alignment bracket provided with the abovementioned rotating fixing elements is described, for example, in
European patent EP 1043816 . Each of the two arms of the bracket has a fixing element rotatably inserted inside a circular seat formed in the said arm. The fixing element consists of a cylindrical body which acts as a rotating pivot inside the abovementioned circular seat and is provided at one end with a tongue projecting perpendicularly from its axis. This tongue, which is formed as one piece with the cylindrical body, is eccentric with respect to the axis of the latter and, consequently, following a rotation of the cylindrical body, is able to pass from a releasing position, where the said tongue is retracted inside the contour of the arm and does not interfere with the profile, into a locking position, where the tongue, projecting from the contour of the arm, is forced against the profile and is able to fix rigidly the bracket to the said profile. During the rotating movement of the tongue it engages with the profile and imparts to it a longitudinal sliding movement which favours alignment with the other profile in the joining zone. The flat tongue portion which is intended to come into contact with the profile is shaped in the manner of an arc of a circumference and is provided with a series of teeth able to increase gripping thereof on the said profile. - The alignment bracket described in the
patent EP 1048816 has the drawback that the thrust exerted by the tongues on the profiles is concentrated substantially in a single point. This adversely affects the stability of engagement of the bracket with the profile and may result, in certain mechanical stress conditions, to gradual loosening of the fixing means and therefore a deviation (or misalignment) of the profiles. - In this situation, therefore, an object of the present invention is to eliminate the drawbacks of the known art mentioned above by providing an alignment bracket for fixtures which ensures more stable engagement with the profiles.
- Another object of the present invention is to provide an alignment bracket for fixtures which is operationally entirely safe and reliable.
- A further object of the present invention is to provide an alignment bracket for fixtures which is simple and inexpensive to produce.
- The technical features of the invention, in accordance with the abovementioned objects, may be clearly determined from the content of the claims indicated below and the advantages thereof will emerge more clearly from the detailed description which follows, provided with reference to the accompanying drawings, which show a purely exemplary and non-limiting example of embodiment and where:

Figure 8 shows a view of a detail of the alignment bracket according toFigure 1 , relating to the mechanical connection between the pivot ofFigure 4 and the forked element ofFigure 6 . - With reference to the accompanying drawings, 1 denotes the alignment bracket for fixtures according to the invention. This bracket 1 is intended, in particular, for the assembly of frames for thermal break fixtures, but may also be used as a force-fitting bracket during the assembly of frames for cold profile fixtures, on its own or in addition to other brackets also of the conventional type.
- Each thermal break profile is composed of a main portion, intended to form the outer surround of the fixture, and a secondary portion, intended to form the inner surround. The two portions are connected together by a further heat-insulating portion. The alignment bracket 1 according to the invention is mounted in the zone where the secondary portions of a first and a second profile I and II of a thermal break frame are joined together with the aim of aligning the two profiles and keeping them in a coplanar relationship. The actual structural connection between the two profiles I and II is performed along their two main portions by means of an ordinary force-fitting bracket (not shown).
- Operationally speaking, the alignment bracket 1 according to the invention is associated with the two profiles at the same time as the force-fitting bracket during assembly of the frame. Each thermal break profile is provided with a special longitudinal groove S formed in the abovementioned inner portion. This groove extends longitudinally along the entire length of the profile I and II and is delimited by two opposite parallel edges, one of which, denoted by B2, is situated closer to the inner side of the profile than the other one denoted by B1.
- The alignment bracket according to the invention consists essentially of a joining angle-
piece 2 formed by a flat plate - preferably made of aluminium alloy or possibly steel - and having two mutuallyperpendicular arms - Once mounted, the bracket 1 is therefore situated astride the joining zone of the two profiles I and II. Each
arm suitable means 4 for ensuring fixing to the profile, which are able to lock the said arm inside the groove S and at the same time impart to the profile I and II an additional sliding movement towards the joining zone. For this purpose, the fixing means 4 comprise apivot 5, which is rotatably inserted in eacharm shaped body 6, which is eccentrically connected to thepivot 5 and is inserted inside afirst guide seat arm pivot 5 rotates, it causes a displacement of theshaped element 6 relative to thearm shaped element 6 has anengaging portion 64 which, following the abovementioned displacement, projects more from the arm and pushes against the edge B2 of the groove S. - Functionally speaking, the
shaped body 6 is able to move between a releasingposition 64, where theengaging portion 64 does not interfere with the longitudinal edge B2 so as to leave thearm engaging portion 64 is instead forced against the edge B2 so as to lock thecorresponding arm arm - In
Figure 2 , the fixing means 4 of the arm denoted by 3a are shown arranged in the locking position, while the fixing means 4 of the arm denoted by 3b are shown arranged in the releasing position. - In greater detail, during the transition from said releasing position into said locking position, the
pivot 5 and the connection between theshaped body 6 and theguide seat pivot 5 and is substantially parallel to the edge B2 of the groove S. During the abovementioned rotary and translatory movement, theengaging portion 64 causes the sliding movement of the profile I, II towards the joining zone in a direction substantially parallel to the edges B, B2 of the groove S. Owing to this movement theengaging portion 64 is brought so as to rest completely against the edge B2 of the groove S, thus ensuring extremely stable fixing of the bracket 1 to the profile. - Each
arm piece 2 has afirst side surface 23 in contact with the edge B1 of the groove S and asecond side surface 24 which faces the edge B2 and is slightly spaced from the latter owing to the presence of the engagingportion 64 of the shapedbody 6. - In accordance with other embodiments not shown here, the two
arms - In accordance with the preferred embodiment of the invention, constructionally speaking the
guide seat piece 2. - In greater detail, each inset zone extends from the from the
second side surface 24 towards the inside of eacharm rounded eyelet 27 substantially parallel to the centre axis X of the said arm. - Each
arm hole 20 for receiving thepivot 5, which is formed inside the inset zone in a remote position from theeyelet 27. - In accordance with the preferred embodiment, which can be seen in particular in
Figures 4 and 5 , thepivot 5 consists of a maincylindrical body 50 which is inserted inside the through-hole 20 so as to rotate about the common axis of rotation Y and is provided at its twoends 5' and 5" with a first and a secondcylindrical lug lugs main body 50. When thepivot 5 is inserted inside the through-hole 2, the- twolugs hole 20 in the two inset zones formed on the sides of each arm. - Preferably, the rotation of the
pivot 5 occurs over an arc of a circumference and is limited by the interference of anib 53, provided on the outer surface of the maincylindrical body 50, with two end-of-travel shoulders provided in agroove 28 for receiving the saidnib 53, formed adjacent to thehole 20. Thenib 23, moving along thisgroove 28, is able to pass between two end-of-travel positions corresponding to the releasing position and the locking position, respectively, of the engagingportion 64. - Advantageously, the
pivot 5 is provided on at least one of its end surfaces with acoaxial seat 500 envisaged for engagement of a suitable operating tool, such as a screwdriver or a hexagonal-head spanner for example, so as to allow an operator to forcibly rotate the saidpivot 5 during assembly of the frame. - As can be seen from
Figures 6, 7 and 8 , the shapedbody 6 consists preferably of a forked element defined by twoparallel flanges 60' and 60" which are connected together by a joiningsection 70. The latter defines, together with a projecting part, the engagingportion 64 of the shapedbody 6. This projecting part of the shapedbody 6 has a longitudinal extension in a direction substantially parallel to the edge B2 of the groove and, in particular, to the centre axis X of the corresponding arm, on which the said shapedbody 6 is mounted. - Advantageously, the engaging
portion 64 may also be provided with a series of teeth (not shown) able to increase the friction with the edge B2 of the groove S. - As already mentioned above, the shaped
body 6 is mechanically connected to thearm pivot 5. For this purpose, each of the twoflanges 60' and 60" is provided with acircular opening 68 able to allow form-fitting engagement with the twocylindrical lugs pivot 5. - In this situation, the two
parallel flanges 60' and 60" are inserted inside the twoguide seats arm portion 64 projecting from the arm along thesecond side surface 24 of the latter. - In greater detail, as can be seen in particular from
Figures 2 and6 , each of the twoparallel flanges 60' and 60" has an elongatedportion 62 which is housed in a guided manner inside theeyelet 27 of therespective guide seat - Operationally speaking, when the
pivot 5 is rotated, the eccentriccylindrical portions body 6 is pivotably mounted impart to the latter a movement guided by the engagement of theelongated parts 62 inside theeyelets 27 of the guide seats 25,26. - The eccentricity of the
cylindrical portions body 6 are suitably designed to impart to the engaging portion 64 a rotary and translatory movement having a pressure component perpendicular to the edge B2 and a pulling component parallel to the said edge B2. During this movement the abovementioned engagingportion 64 bears against the edge B2 along the whole of its longitudinal extension. - Obviously, the
guide seat body 6 without thereby departing from the scope of protection of the present patent. - During the transition from the releasing position to the locking position, the engaging
portion 64 protrudes towards the edge B2 while remaining substantially parallel to the latter and to the centre axis X of the corresponding arm of the bracket 1. The engagingportion 64 may therefore come into contact with the edge B2 of the groove S, causing the sliding of the associated profile I, II towards the joining zone in a direction substantially parallel to the centre axis X of thecorresponding arm - Owing to the rotary and translatory movement imparted to the engaging
portion 64 as well as the particular form of the saidportion 64, it is possible to obtain a more stable engagement with the profiles than in the cited solutions of the known art and, in particular, the thrusting force may be distributed over a wider area of the edge B2 of the groove S. - In accordance with a particular solution of the invention not shown in the Figures, the shaped
body 6 consists of asingle flange 6 which is associated with a single side of the arm of the bracket 1, connected to thepivot 5 via a single eccentric lug of thepivot 5 and housed inside a single guide seat of the arm. - The invention thus conceived therefore achieves the predefined objects.
- Obviously, it may also assume in its practical embodiment forms and configurations different from that illustrated above without thereby departing from the present scope of the invention, as defined by the appended claims.
