Definitions

  • the present invention relates to a minimum-force compensator according to the preamble of claim 1 for compensating for play due to wear and vertical give in the structure of doors and gates, anomalies which are encountered in particular when the leaves are large, heavy and of considerable width (US1 409 468 A).
  • the invention was designed to be stably fitted between the tree edge of the door or gate (P/C) and the roller unit R (roller and associated bracket with pin and plate) selected from the many on sale for fixing to the bottom edge of the leaf in order to reduce the operating load on the pivots in use ( Figure 1).
  • P/C tree edge of the door or gate
  • R roller unit R
  • the advantages of the invention, in comparison with the prior art, are clear with regard to ease of assembly, calibration and accuracy of the compensator, and thereby also in respect of cost and improved quality.
  • the compensator of the invention according to claim 1 has the advantage of compensating for vertical play in doors and gates in a gradual and repeatable manner which can be corrected at any time and with minimum effort, even in the case of very heavy doors. This is made possible by the fact that the vertical position of the wheel assembly relative to the door or gate is not unchangeable, thanks to the fitting of the intermediate compensator mechanism of the invention, whilst being defined and fixed once adjustment has been effected.
  • the micrometric compensator of the invention is therefore constituted by an upper metal portion 1, a lower metal portion 2, slidingly coupled to the portion 1 and being fixable at its lower region to the wheel assembly by means of screws or welding, by a female element or threaded nut 4 securely fixed to the metal portion 1 with its axis parallel to the sliding direction of the portion 2 relative to the portion 1, this direction will be vertical once the assembly is mounted for operation, and by a robust pressure screw 3 engaged in the female element 4 ( Figure 1).
  • the final operation consists in securely locking the screw 3 by means of a lock-nut 7 and in slidably coupling the portions 1 and 2 by means of specially provided play-compensation and locking screws 8.
  • the device of the invention is adapted to the requirements of the market, to different loads according to the frontal dimensions of doors or gates to which it is to be fitted, to the projection of the wheel unit with respect to the flat fixing plate (5) of the door or gate, and to the more or less advanced position of the female element 4 relative to the plate 5.
  • the said female element 4 may be integral to, or formed in the upper metal portion 1, or in the lower portion 2, with the screw 3 acting accordingly downwards on the portion 2 or upwards on the portion 1.
  • a metal counter plate (6) which, mounted in a mirror-image coupling configuration to the plate (5) on the other face of the door or gate (P/C) serves to largely ensure that, the plate stays fixed in place for longer, if through-bolts and nuts are used.
