Definitions

  • the present invention relates to an elevator door coupling apparatus and more particularly to a coupling apparatus able to engage and release elevator car door and elevator shaft door.
  • a correctly timing of driving is commonly achieved by coupling apparatuses comprising at least a first engaging member on the elevator car door fitted to engage a second engaged member on each shaft door.
  • an unique driving motor is usually provided on the elevator car, said motor controlling the first member of the coupling apparatus engaging the second member thus permitting the aforementioned almost synchronous movement of elevator car door and elevator shaft door.
  • the driving motor can be shared with the car door operator through suited transmission system or, alternatively, can be a dedicated electric motor.
  • said first engaging member of the coupling apparatus is constituted by a hinged parallelogram in which a pair of opposed vertical arms-where vertical is the direction parallel to the elevator lifting movement - are pivotally joined by a couple of rotatable arms whilst the engaged member is constituted by a pair of rollers rotatably fixed at opposite ends of a lever, said lever being in turn operatively connected to locking system of the elevator shaft door.
  • said lever of the engaged member In locked position said lever of the engaged member is inclined at a given angle so as to misalign in respect of vertical direction said rollers and define a gap therebetween.
  • the member of the coupling apparatus is arranged in the current elevator plants so that the vertical arms of the hinged parallelogram pass the gap between rollers of each shaft door till the elevator car reaches the floor requested.
  • the obvious variable clearances existing between the engaging member and pair of rollers at each floor together with the unavoidable horizontal vibrations of the elevator car during its movement generate continuous impacts between said members that result in further vibrations and excessive stress of the apparatus.
  • the above drawbacks of the known coupling apparatuses need to be overcome.
  • Main object of the present invention is therefore to provide an elevator door coupling apparatus which is not affected by vibrations related to elevator car speed causing impacts between members of the same coupling apparatus.
  • Another object of the present invention is then to provide an elevator door coupling apparatus which solves issue regarding variable clearances during engagement of members of the same coupling apparatus.
  • an elevator door coupling apparatus 100 comprising a pair of vertical arms 10, a lower and an upper ring 20.
  • Each ring 20 has diametrically opposed protrusions 21 and 22 and also peripheral slots 23 and 24 formed between said protrusions 21 and 22.
  • Each vertical arm 10 is hinged to both lower and upper rings 20 at said one protrusion 21 or 22 such that a hinged parallelogram is formed.
  • a pair of annular members 30 are dimensioned in order to be concentrically fitted in the upper and lower rings 20, respectively, and adjustably fixed thereto by bolts 25 inserted in said slots 23 and 24: in particular, said members 30 are internally threaded according to a helical profile 31.
  • a pair of internally hollow cylinders 40 are threaded on a portion of their external surface so as to have a profile 41 mating said helical profile 31, the remaining portion of said external surface being a toothed surface 42.
  • Said hollow cylinders 40 are pivotally fixed, through a pair of pin 50 fitting the hollow of said cylinders 40 by a set of roller cages 51, to a supporting plate 60 at separate positions along a vertical direction.
  • Said supporting plate 60 is also configured to pivotally support, on its top right hand side, a transmission sprocket wheel 70 of a chain 75, connected at a first end 76 thereof to a spring (schematically shown in the figures) and at second end 77 to said sprocket wheel 70; the spring is also connected to the supporting plate 60 such that it assures a constant pulling action for the chain 75.
  • a second supporting plate 65 connected fixedly to the elevator car door operator (not shown) and slideably to the supporting plate 60, supports a snub pin 95 around which a chain 90 is partially wound.
  • Said chain 90 has a first end 96 fixed to said second supporting plate 65 by a pair of bolts and a second end connected to periphery of a second smaller wheel (not shown), said second smaller wheel being coaxially mounted to said sprocket wheel 70 and integrally movable therewith.
  • a toothed belt 80 is selected in order to mate with portion of toothed surface 42 of the cylinders 40 and wound around them in a closed configuration; suitable coupling means are provided for coupling said toothed belt 80 to said chain 75.
  • a profiled plate 61 having a L-shaped guide 63, is fixed to said supporting plate 60 under the lower cylinder 40; a pin 62 protruding from the lower annular member 30 is dimensioned in order to engage the guide 63 (see fig. 3b ).
  • the coupling apparatus 100 with reference to the door opening operation, from a first retracted position P1 ( fig. 1a ) and in a closed condition C1 axially moves towards a second advanced position P2 between rollers of the shaft door and then displaced in an opened condition C2 ( fig. 3 ) so as to engage said rollers: the supporting plate 65 is horizontally drawn by the door operator thus causing the chain 90 to be pulled and said second wheel to be accordingly rotated.
  • the sprocket wheel 70 actuated by said second wheel, clockwisely rotates and upwardly moves both the chain 75 and the toothed belt 80 fixed, as above said, to the chain 75.
  • the cylinders 40 are therefore driven by said toothed belt 80 mating toothed portion of their external surfaces 42 and synchronously rotate so as to allow the annular members 30 to advance by mating action of helical profiles 31 and 41. Advancing movement of the annular members 30 is controlled by said pin 62 which is engaged in the guide 63 of the profiled plate 61.
  • the pair of arms 10 is disengaged from rollers and the corresponding lever of the elevator shaft door locking system by a reverse rotation of said cylinders 40 resulting from reverse movement of the car door operator; the action of the return spring arranged between the end 76 of the chain 75 and a fixed point of the supporting plate 60 assures a reverse counterclockwise rotation of the sprocket wheel 75 which, in turn, rotates the smaller wheel and pulls the chain 95 connected thereto.
  • the toothed belt 80 can be therefore reversely actuated thus causing the cylinders 40, through the annular members 30, to rotate the pair of arms 10 in the closed condition C1 and, still withdrawn by the annular member 30 mating the cylinders 40, to move backwards to the retracted position P1.
  • the pair of cylinders 40, the pair of annular members 30 and the belt 80 can be so considered as constituting an unique assembly, said assembly serving for displacing the engaging members or arms 10 from the retracted position to the advanced position, said engaging members being actuated by said rings 20.
  • the assembly can be also driven by car door operator by interposing transmission means constituted by chains 75 and 95 and the coaxially arranged sprocket wheel 70 and smaller wheel. It is to be envisioned that ratio between diameters of the sprocket wheel 70 and the smaller wheel is selected for amplifying movement of the chain 75 in respect of the movement of the chain 95 thus adjusting the door operator stroke to advanced movement required for the coupling apparatus 100 generally being 20 mm.
  • the helical thread pitch must be also selected in order to comply with the desired advancing movement of the apparatus 100.
