Definitions

  • the present invention refers to a suspension mechanism for fitting, sliding doors, as for example those used in railroad carriages and the like, doors, which in locked position, remain fitted inside the carriage carbody, establishing external surface smoothness with the same, in order to improve the aerodynamic penetration conditions, and which must be initially disengaged in order to open them from said carbody, for the subsequent conduction of the longitudinal sliding, which is necessary for their aperture.
  • the object of the invention is to improve the fitting conditions of the door inside the carbody, for an improved closure.
  • folding doors pose a wide and varied range of problems which make them, at the present moment to be found totally in disuse, having been replaced by sliding or runner doors.
  • one of the solutions which has been used as being the most appropriate for this type of doors, consists in using a horizontal and upper, telescopic guide, from which the door is suspended, said guide, besides being capable of telescopically extending and shortening, is capable of displacement of the totality of its assembly, when it is unfolded, towards the front, with the purpose of establishing the fitting and unfitting operations of the same, from the corresponding housing of the carriage carbody.
  • the housing of the carriage carbody must be conceived, designed and dimensioned to permit this slanting movement of the doors, which signifies a structural complexity of the closure which is appreciably greater than if said doors conducted the fitting and disengaging operation with a perfectly perpendicular trajectory to the general plane of its mouth in the carriage carbody.
  • Document GB-2 191 528 is known, which discloses a door support having two extensible bars upon which the support profile and doors rolling are fastened. These extensible bars allow the door take out or get in to facilitate its opening.
  • Documento FR-1 461 213 is also know relating to a device coupled to lorries, wagons, etc..., having a profile which is constituted in the welding and support of sliding doors, which is supported by extensible elements of approach or retreat of these doors with respect to the vehicle.
  • Document DE-A-2 219 176 is known relating to a mechanism for sliding doors that uses a runner mechanism for the door displacement, the said door being suspended through both arms that allow the door to effect a revolving displacement movement both on its fitting and unfitting from the opening of the vehicle door.
  • the invention provides a sliding door having the features according to claim 1.
  • the sliding door which the invention proposes, solves in a completely satisfactory manner, the previously indicated problem, permitting, in compliance with the main objective of said invention, that the sliding door conducts its fitting and disengaging operations with a perfectly perpendicular movement as regards the general fitting plane of the same.
  • the pair of doors which generally establish as a whole, the closure of a specific gap, are assembled on respective telescopic guides, each one of these guides forming integral part of a support to which in turn, a, pair of rods form integral part, which emerge perpendicular to the end zones of said support and which are capable of sliding in relation to the carbody of the carriage or element involved, in the direction of its own rods, that is to say, in a perfectly perpendicular direction to the locking plane.
  • each one of these rods shall be guided by a pair of sheaves, said rods being also preferably equipped with a run limiting stop, which, obviously, limits the displacement of the door in disengaging direction of the same.
  • each one of these rods include a rack in correspondence with the abutment generatrix of one of the sheaves, whilst the corresponding sheave includes a complementary toothing, the respective sheaves of the different rods remaining related to each other by means of a common rod which forces them to a synchronized movement, which is the equivalent to an also synchronized movement of the corresponding rods through the respective racks.
  • this solution may be replaced by a torsion bar, suitably forming integral part of the rear and free end of the rods, said bar forcing them, in a like manner, to a parallel and synchronized movement.
  • the mechanism of the invention centres its characteristics in the fact, that the telescopic guide module (3) placed in counterposition to that for the attachment of the door (1), forms integral part of a support (5), elongated in correspondence with the actual guide (3), to which, in turn, various rods (6) form integral part in the proximity of its end which, attached perpendicular to the support (5), extend horizontally towards the inside of the carriage (4), finished off at its free end by various stops (7), which shall be herewith described.
  • rods (6) intended for supporting the telescopic guide (3), and through the same, the sliding door (1), is related to the carriage (4) or element involved, each one of them, through a pair of sheaves (8) and (9), and each, peripherically grooved in correspondence with the rods (6) curvature, one placed below, which is referenced with (8), in the proximities of the support (5), whilst the other, the one referenced with (9), is placed above, and in a considerably more removed location, with the object of absorbing the stresses tending towards the tilting of the rods (6), generated by the actual weight of the door (1).
  • the upper-interior sheave (9) in addition to acting as guiding means for the rods (6), acts as limiting stop for the axial run of said rods (6), when the stop (7) incides on the same, which forms integral part with the free end of said rods (6), said stop however, may incide, in order to limit said movement, on any other fixed element of the carriage structure (4).
  • the door (1) is capable of outwards displacement, in a perfectly perpendicular movement as regards the general closing plane, due to the displacement of its pair of rods (6), on the corresponding pair of sheaves (8) and (9), up to a limit situation defined by the stop (7) in which the telescopic guide (3) is placed totally outside the carbody (4) of the carriage, remaining in a condition which permits the transversal displacement of the door (1), for the corresponding opening operation, an opposing operation being obviously established for the closing operation.
  • the door (1) or in its case, the pair of complementary doors (1), shall be activated by any suitable pushing means, such as for example, a pneumatic circuit which acts, for example, on the support (5), pushing or pulling the same.
  • a pneumatic circuit which acts, for example, on the support (5), pushing or pulling the same.
  • each rod (6) may be equipped with a rack (10), for example on the upper support generatrix of the sheave (9), said sheave (9) being provided with a complementary toothing (11), and the sheaves (9) corresponding to the different rods (6) of the door or doors (1), forming integral part to each other through a common axis (12), which forces them to a synchronized movement, in such a manner that it is impossible that any of said rods (6) may become misadjusted in their advancing or retreating longitudinal movement as regards the rest of the group.
  • a rack (10) for example on the upper support generatrix of the sheave (9), said sheave (9) being provided with a complementary toothing (11), and the sheaves (9) corresponding to the different rods (6) of the door or doors (1), forming integral part to each other through a common axis (12), which forces them to a synchronized movement, in such a manner that it is impossible that any of said rods (6) may become misadjusted in their
  • this synchronization in the movement of the different rods (6) may be also conducted by means of a torsion bar, conveniently forming integral part with the rear and free end of the same.
