Definitions

  • the present invention relates to a junction piece making it possible to assemble by approximation two tubular or almost tubular sections cut from tabs at a given angle, for the production of panel frames, doors, windows or shutters.
  • junction pieces are of the type comprising a double pin square, one symmetrical outside, truncated on the angle and generally comprising a thread capable of receiving a spacer screw, the other symmetrical inside, truncated on the 'angle for the support of said spacer screw, each branch of the double bracket being received in a tubular cavity of the corresponding profile whose external wall has a lumen into which the associated pin can penetrate for the bringing together and assembly of said profiles.
  • French Patent 2,332,447 describes a junction piece of this type, in which two conical springs are arranged between the outer and inner brackets, each spring being held in place by a groove in the inner bracket and the recess of a shoulder pin mounted on the outer bracket, the free end of said pin having a shoulder received in the corresponding lumen of the profile.
  • Such a junction piece has several drawbacks. First, it assumes a set of seven parts, whose bulk in thickness remains significant. Then, the maintenance of the profiles is not perfect, because the contact between the connecting piece and the external wall of the cavity of each profile is limited to the shoulder of the corresponding pin. Finally, the points of application of the support forces produced for the assembly (bosses of the inner bracket on the one hand, shoulders of the pins of the outer bracket on the other hand) are arranged substantially opposite, due to the fact of the presence of the springs, therefore in a direction substantially at 45 ° from that of the tightening, which induces an undesirable torque.
  • the object of the invention is to propose a junction piece making it possible to carry out, in a single operation, a perfect assembly of two tubular profiles whose internal cavities can be of particularly small dimensions, it being understood that said profiles can be closed or not , the term tubular to be understood in a broad sense.
  • Another object of the invention is also to produce a junction piece comprising the minimum of components, which are not likely to separate when the piece is not yet assembled.
  • the junction piece considered making it possible to assemble by approximation two tubular sections cut at a given angle, comprising a double square with pawns, one symmetrical outside, truncated on the angle and comprising a means of spacing defining a tightening direction, the other symmetrical interior, truncated on the angle for the support of said spacing means, each branch of the double bracket being received in a tubular cavity of the corresponding profile whose external wall has a lumen into which the associated pin can penetrate for bringing together and assembling said sections, the outer bracket having internal facets in the vicinity of the end of each of its branches, the plane of said facets being substantially parallel to the tightening direction l ' inner square being rigid and in contact by its free ends with said facets, each branch of the double square having a pin projecting from the facet e external of the external bracket, the contact of contact with the external wall of the associated tubular cavity being ensured by said external face of the external bracket (see p.
  • FR-A-2 429 350 is characterized in that the outer bracket is also rigid and the inner bracket has a protruding boss on its internal face, ensuring bearing contact with the internal wall of the tubular cavity, the clearance of the inner bracket in the outer bracket being limited above by a re-entrant flange provided at the end of each branch of the outer bracket.
  • the pin and the boss of each branch of the double bracket remain on an axis substantially parallel to the plane of the adjacent face of said branch, which prevents any appearance of an unfavorable induced torque during the final assembly.
  • the pin of each branch of the double bracket is provided substantially at half-distance from said branch.
  • the re-entrant flange substantially trapezoidal, terminates a 90 ° return from the corresponding end of the branch of the outer bracket.
  • the clearance of the inner bracket in the outer bracket is limited lower by the contact of their opposite faces, the bosses of the inner bracket then projecting slightly from the inner edge of the corresponding end of the branch of the 'outside bracket, or by the contact of two stops formed on said opposite faces, for each branch of the double bracket; this makes it possible to assemble profiles with particularly narrow tubes, without compromising the security of the assembly.
  • the rigid external and internal brackets each form a right angle; similarly, the spacing means will for example consist of a screw received in a thread on the outer bracket.
  • the junction piece illustrated in Figure 1 is essentially constituted by a double square 1, the symmetrical outer bracket 2 being truncated on the angle and here comprising a thread 3 capable of receiving a spacer screw 4, the inner bracket symmetrical 5 also being truncated on the angle for the support of said spacer screw.
  • spacer means could be used, for example a pivoting cam.
  • the outer bracket 2 is rigid, and has internal facets 6 in the vicinity of the end of each of its branches 7, the plane of said facets being substantially parallel to the axis of the spacer screw 4 (clamping axis 8), the inner bracket 5, also rigid, being in contact by the free ends of its branches 9 with the facets 6; each branch of the double square 1 has a pin 10 projecting from the external face 12 of the external bracket 2, and a boss 11 projecting from the internal face 13 of the internal bracket 5.
  • the junction piece of the invention uses the general principle of pin brackets, according to which each branch of the double bracket is received in a tubular cavity of the corresponding profile, the external wall of which has a lumen into which the associated pin can penetrate, for bringing together and assembling the tubular profiles.
  • the bearing contact with the external and internal walls of the associated tubular cavity is here respectively provided by the external face 12 of the external bracket 2 and the boss 11 of the internal bracket 5, this support contact ensuring perfect maintenance of the assembled profiles.
  • the internal dimension of the tubing that is to say the spacing between the external wall 16, 16 'and the internal wall 17, 17' of the sections 14, 14 'respectively, can therefore be particularly reduced thanks to the ultra character - flat of the double bracket of the invention, the maximum height of which (determined by the spacing between pin 10 and adjacent boss 11) can be particularly small, the thickness of the outer 2 and inner 5 brackets however having to be sufficient for is preserved their rigidity in bending.
  • the maximum height of the double bracket before tightening will be slightly less than the internal dimension of the tubing so as to be accommodated therein easily, the space between pin 10 and external wall 16 being exaggerated in FIG. 2A for to facilitate clarity.
  • Each profile 14, 14 ' has, at its outer wall 16, 16', an oblong opening 18, 18 'whose length must be greater than the diameter of the pins 10 engaging it, and an end notch 19, 19 'allowing the passage of the spacer screw 4 and the associated tightening tool.
  • the slots 18, 18 ′ are made so that the distance between their inner edge and the apex of the angle is substantially equal to the distance between the pin and the apex of the angle of the outer square, so that during tightening, the pins can come close on the canvas of the profiles.
  • the “free expansion of the double bracket of the invention during tightening is possible thanks to the play existing between the diameter of the pin and the associated oblong lumen.
  • the pins 10 undergo a translational movement in an oblique direction to arrive at the final position of Figure 2B where the assembly is completed.
  • the pin 10 and the boss 11 of each branch of the double bracket remain located on an axis substantially parallel to the plane of the adjacent facet 6 of said branch, which is let us recall it parallel to the tightening axis 8.
  • This oblique correspondence is illustrated by the delta interval in FIG. 2B, the result of such an arrangement being that any occurrence of an unfavorable induced torque is avoided during of the final assembly.
  • the pin 10 of this branch 7 of the outer bracket 2 is then provided substantially at mid-distance from said branch, which ensures, in combination with the bosses 11 of the inner bracket 5, an excellent distribution of forces.
  • the movement of the inner bracket 5 in the outer bracket 2 is limited above by a re-entrant flange 20 provided at the end of each branch 7 of the outer bracket 2, said flange, substantially trapezoidal, ending a return to 90 ° of the corresponding end of said branch. This makes it possible in particular to avoid any risk of loss of the internal bracket before the assembly of the junction piece on the tubular section to be assembled.
  • the clearance of the inner bracket 5 in the outer bracket 2 is itself lowered either by the contact of their opposite face, as illustrated in FIG. 2A, or by the contact of stops 21 and 22 formed on their opposite face for each branch 7, 9 of the double bracket, the bosses 11 of the inner bracket then projecting slightly from the inner edge of the corresponding end of the branch 7 of the outer bracket 2.
  • junction piece of the invention makes it possible to assemble by bringing together two tubular or almost tubular sections cut at an angle different from 90 °: however, in this case, the principle of the internal facets parallel to the axis tightening remains, as well as the other essential characteristic of the invention according to which the bearing contact with the external and internal walls of the associated tubular cavity is respectively ensured by the external faces of the external bracket and the bosses of the inner square.
  • Figure 3 gives an illustration of the position of the junction piece which has just been described and of the two tubular sections of which said piece assembles by bringing their cut closer together.
  • the junction piece comprising only three components, thus makes it possible to carry out, in a single operation, a perfect assembly of tubular profiles whose internal cavities can be of particularly reduced dimensions.
  • the extra-flat nature of the double square and the perfect assembly that it allows to achieve represents an important advance in the assembly technique, in particular compared to the devices illustrated in the French patents cited above.
  • the outer and inner brackets forming the junction piece have a simple structure allowing their easy realization from profiles, preferably aluminum, with a minimum of machining.
