Definitions

  • This patent refers to a system for joining section bars used in facades (both to mullions and transoms, be they structural or semi-structural) band frames, movable walls and in general wherever mullions are to be joined to transoms with mitred joints, without additional work.
  • Such a system is known from document BE-A-1003563.
  • transoms are to be inserted - to the adjustment of the transoms themselves.
  • the latter after having been cut to the desired length, are milled or sheared in order to remove a portion of their outer wall, close to the ends.
  • the transoms are then frontally inserted into side supports which have been fastened to the mullions by means of screws and are tightly locked to them with additional screws.
  • transom ends are milled once again, so as to obtain two projections, one on each side, directing the water into the above mentioned channel.
  • mullion and transom preparation costs are very high, given the number of adjustments to be performed: double milling or shearing of transoms, milling of mullions, double perforation of mullions (in order to create the holes in which both the screws for the side supports and those needed for joining the transoms to the mullions will be fastened).
  • transoms are cut to the desired length. The ends are then closed with plastic plugs which act both as gaskets and dilatation compensators. Finally, transoms and mullions are joined together with metal bars which are placed horizontally between the two and fastened to them by means of screws. The metal bars are fitted into special transom channels or chambers, creating a typical cross-shaped joint where screws are essential to keep the structure tightly fastened. Apart from the transoms' low resistance to torsion stress, it is however necessary to pierce or shear both the mullions and the transoms, which makes preparation of the various parts expensive, although to a lesser extent.
  • the aim of this invention is to offer users a section bar linking system which does not require extra adjustments other than the cutting of mullions and transoms during the making of facades, band frames and movable walls. Consequently, this invention also aims at enabling frontal assembly and disassembly of section bars at extremely low costs, thus offering great economic advantages.
  • the section bars used for the making of transoms are provided with at least one channel (whose longitudinal axis is parallel to that of the section bars), developing vertically.
  • the section bars used for the making of mullions are provided with at least two grooves whose longitudinal axis is parallel to that of the section bars and symmetrical to the central beams.
  • each groove is provided with at least one coupling jaw, one holding jaw, and one inclined plane.
  • Each groove can be divided into two channels by a sufficiently flexible fin, whose longitudinal axis is parallel to that of the mullion, which has to be provided with at least one coupling and one holding jaw.
  • a projection creates the inclined plane, while at the end of the other channel a projection creates a housing.
  • the insert is provided with at least one connection beam perpendicular to its body.
  • the body of each insert is housed in at least one of the transom channels whereas the end supplied with the connection beam inevitably protrudes from the channel itself.
  • the connection beam may vary in shape but in all cases has to be provided with at least one coupling and one holding jaw.
  • the connection beam's end can be formed by a terminal, complementary or not to the above mentioned housing.
  • the insert may also be supplied with a guide beam placed perpendicularly to the insert's body and in the same direction as the connection beam. This guide beam may be provided with a terminal, preferably placed at its distal end and perpendicularly to the beam.
  • the insert body may be subdivided into two or more sections which are parallel to the transoms, joining at the mullion.
  • the insert is provided with two or more holes, threaded or not, at least one of which is to be located on the insert's body itself and another near the connection beam. These holes hold screws or dowels.
  • a metal profile spacer may be used, having a varied section structure.
  • the spacer which may host the vertical sealing gasket and act as a support for the shutters' retaining elements, is fixed to the mullion by means of joints, gaskets or any other simple fitting method. It may have diverse shapes and may or may not be provided with a coupling jaw to be inserted in at least one of the mullion's jaws. The spacer is inserted into a specific slot for fitting or in at least one of the channels.
  • Each transom end may be closed by a tight plug, formed by a body having the same profile as the transom, with a support protruding from it and facing oppositely to the transom end.
  • the support is provided with one or more slits whose clear span is the same size as that of the insert's body and may also be provided with horizontal holes.
  • Insert 1 is formed by a body 1.1 and a connection beam 1.2 which is perpendicular to the body itself.
  • Body 1.1 of insert 1 is divided into two parts which are parallel to transoms 3, joined together near beam 1.2.
  • Connection beam 1.2 is provided with a coupling jaw 1.3 and a holding jaw 1.4.
  • Insert 1 is provided with four holes, two threaded holes 1.5 along body 1.1 and two non-threaded holes 1.6 near connection beam 1.2.
  • the section bars used to create transoms 3 have a box-like body 3.1 and two channels 3.2 whose longitudinal axis is parallel to that of transoms 3, developing vertically.
  • the two parts of body 1.1 of insert 1 are fitted into channels 3.2, whereas the extremity provided with connection beam 1.2 protrudes from channels 3.2.
  • connection beam 1.2 protrudes from the transom 3 since there is a predetermined stop point given by the end of the channel that is created in the middle of the two parts that make up the body of the insert 1.
  • the section bars used to create mullions 2 have a box-like body 2.1 and a double seat 2.2, whose longitudinal axis is parallel to that of the section bars and rigid edges.
  • the central beams 2.3 holding the section bar which blocks the glass or panel, are placed between the two seats 2.2.
  • each seat 2.2 is closed by fin 2.4, whose longitudinal axis is parallel to that of mullion 2.
  • Fin 2.4 is provided with a coupling jaw 2.5.
  • a holding jaw 2.6 is placed opposite to jaw 2.5 on the edge of seat 2.2 facing the external side of mullion 2.
  • At the bottom of each seat 2.2 a projection creates inclined plane 2.7.
  • the edge facing central beams 2.3 of seat 2.2 is also inclined, thus forming another inclined plane, 2.8.
  • a third section bar is used both as an internal glass-holder and as a spacer, 4. It is formed by body 4.1 which is provided with two beams 4.2. Each beam is provided with a coupling jaw, 4.3.
  • a tight plug 5 closes the ends of each transom 3.
  • Each plug 5 is formed by a body 5.1 having the same profile as the tubular portion of transom 3 and a support 5.2 protruding from body 5.1 itself.
  • Plug 5 is crossed by two vertical slits 5.3 having a clear span of the same size as the two parts of body 1.1 of insert 1 and by two horizontal holes 5.4, if required.
  • transom 3 already equipped with plugs 5 and inserts 1 at its extremities, is brought close to mullion 2, frontally.
  • the inserts 1 are fastened to the transom 3 by means of the dowels 7 which are inserted into the threaded holes 1.5 of the body 1.1 of the insert itself.
  • the dowels 7 engrave the walls of the transom 3 itself, preventing the insert 1 from moving in the channels 3.2.
  • the transom 3 is then brought close to the mullion 2, frontally.
  • Connection beam 1.2 of each insert 1 is fitted into each of seats 2.2 until coupling jaw 1.3 clasps to coupling jaw 2.5.
  • the coupling of jaws 1.3 and 2.5 avoids that the group formed by transom 3 and insert 1 should detach from mullion 2.
  • connection beam 1.2 In order to lock insert 1 and prevent the group formed by insert 1 and transom 3 from sliding vertically along mullion 2, screws 6 are inserted in holes 1.6 placed close to connection beam 1.2. These screws, which may also pass through holes 5.4 of plug 5, engrave jaw 2.6, creating horizontal grooves which prevent the above mentioned vertical sliding.
  • connection beam 1.2 of each insert 1 By inserting screws 6 into seat 2.2, connection beam 1.2 of each insert 1 is pushed against its corresponding inclined plane 2.8.
  • the tips of screws 6 use the second inclined plane 2.7 as a fulcrum to lever on plug 5, forcing it to press against mullion 2, thus preventing water leakage and therefore ensuring a tight system.
  • Two dowels 7 prevent insert 1 from moving within channels 3.2 of transom 3.
  • Dowels 7 are inserted in threaded holes 1.5 of body 1.1 of insert 1 engraving the walls of transom 3.
  • Spacer 4 formed by a glass-holding section bar, prevents insert 1 from moving vertically when transom 3 has to support heavy or sudden loads.
  • Both beams 4.2 are inserted in the same seat 2.2 of mullion 2 in which beam 1.2 of insert 1 is housed.
  • Jaws 4.3 couple with coupling jaw 2.5 and holding jaw 2.6 of seat 2.2 thus tightly fastening spacer 4 to mullion 2.
  • Spacer 4 is placed between one insert 1 and the insert above it. Its function is not only that of holding the glass, it also creates a vertical distance between one transom 3 and the other and supports them. Assembly time is therefore reduced since scribing on mullions 2 is no longer necessary.
  • Assembly is sequential and upward oriented. After locking mullions 2 in the desired position, a first transom 3 is fastened to two contiguous mullions 2; then, spacers 4 are fitted into the two mullions 2 placed above the first two inserts 1, then another transom 3 is fastened and the sequence continues until the facade is completed.
  • insert 1 is provided with a terminal 1.7.
  • Insert 1 is also provided with a guiding beam 1.8 placed perpendicularly to body 1.1 and facing the same direction as connection beam 1.2.
  • This second beam 1.8 is also provided with a terminal 1.9, placed at its distal extremity and perpendicular to beam 1.8 itself.
  • the section bars used to create mullions 2 have each double seat 2.2 divided into two channels 2.9 and 2.10, and by fin 2.4, which in this case is thin and flexible. Coupling jaw 2.5 and holding jaw 2.6 are placed on fin 2.4 itself; coupling jaw 2.5 facing channel 2.9 and holding jaw 2.6 facing channel 2.10. At the bottom of channel 2.10, placed towards the middle of mullion 2, a projection creates inclined plane 2.7. At the bottom of channel 2.9, placed towards the external side of mullion 2, a projection 2.11, together with the walls of channel 2.9, creates housing 2.12.
  • the section bar used as spacer 4 is formed by a body 4.1 and two beams 4.2 One of the two beams is provided with a coupling jaw 4.3 while the other beam ends with a fin 4.4 placed perpendicularly to the beam 4.2 itself. Housing 4.5 of body 4.1 holds a vertical gasket 8.
  • transom 3 already equipped with plugs 5 and inserts 1 at its extremities, is frontally brought close to mullion 2.
  • Connection beam 1.2 of each insert 1 is fitted into the most external channel 2.9 and guiding beam 1.8 into the second channel 2.10 until coupling jaw 1.3 clasps to coupling jaw 2.5.
  • the encumbrance of beam 1.2 determines its correct coupling with mullion 2. In fact, it has to be greater than the distance between the lateral extremity of jaw 2.5 and the edge of channel 2.9 (net measure) thus forcing the fin to bend when connection beam 1.2 is inserted into channel 2.9.
  • Screws 6, which also pass through holes 5.4 of plug 5, are inserted into holes 1.6 close to connection beam and engrave holding jaw 2.6.
  • Beam 1.8 guides screws 6 into channel 2.10. The locking with screws 6 is therefore performed by using the more central channel 2.10 and not channel 2.9 where beam 1.2 is housed.
  • fin 2.4 does not bend and its jaw 2.5 does not detach from jaw 1.3 of connection beam 1.2.
  • Both beams 4.2 are inserted in the same channel 2.9 of mullion 2 in which beam 1.2 of insert 1 is housed.
  • Jaw 4.3 couples with coupling jaw 2.5 of fin 2.4.
  • Fin 4.4 of the other beam 4.2 places itself in housing 2.12 thus tightly fastening spacer 4 to mullion 2.
  • Spacer 9 is provided with two beams, 9.1 and 9.2.
  • Beam 9.2 is provided with a coupling jaw 9.3.
  • Beam 9.2 is fitted into the most peripheral channel 2.9 of mullion 2 and its coupling jaw 9.3 Joins with coupling jaw 2.5 of channel 2.10.
  • the other beam 9.1 fits into the other channel 2.10.
  • a second spacer may be used, spacer 10, which has the double function of creating a distance between transoms 3 and supporting the elements which fasten the doors. It is provided with two beams, 10.1 and 10.2 which are fitted into yet another channel 2.14 of mullion 2 having a different position, lateral, and a different function compared to that of channels 2.9 and 2.10 which serve to lock both insert 1 and spacer 9. Spacer 10 is fastened to mullion 2 by means of gasket 11 which is provided with a relief 11.1 intended to occupy groove 2.15 within channel 2.14.
  • a fourth example of realisation of the joining system here described, particularly suitable for interior movable walls, uses an insert 1, a section bar suitable to create mullion 2, of a second section bar creating transom 3 and of a spacer 12. Also in this case the details differ in shape but they have the same characteristics as the ones previously described. Fin 2.4 of mullion 2 is not provided with the inclined plane 2.7, the transom is only provided with one channel 3.2 and spacer 12 has two beams, 12.1 and 12.2, one of which is provided with a coupling jaw 9.3. Beam 12.2 of spacer 12 externally embraces mullion 2. Coupling jaw 12.3 of beam 12.1 of spacer 12 joins with holding jaw 2.6 of channel 2.10.
