Definitions

  • This patent application for an industrial invention concerns a mechanical device for the self-recording of the end of stroke slider, when motorised shutters are being raised, with the result that it is no longer necessary to set said slider, which stops the geared motor at the end of the upward stroke of the shutter; currently the slider is set by means of various trial and error attempts on the part of the installer which is a considerable waste of time.
  • These regulation registers are actually composed of two opposite limit microswitches, the position of which is adjustable and against which there beats a slider screwed along a threaded rod, made to rotate, first in one direction and then in the opposite direction, by the same geared motor which activates the shutter.
  • the limit microswitches are fixed and they are struck by two adjustable screws which protrude from opposite sides of the aforementioned slider.
  • the aim of the instant invention is to eliminate this setting phase by trial and error, having designed a mechanical device, thanks to which, it is possible to obtain self-recording of the end of stroke slider which stops the geared motor, when the shutter has reached its top dead centre.
  • the device is based on the use, for each of the two end of stroke sliders, of a coupling joint, composed of a gear-motor, which can turn idle around the threaded rod, to which each slider is helically coupled and of a drum integral to the aforementioned threaded rod, which is constantly subjected to the returning action of a prestressed spring, which tends to push the drum against said gear,and coupling between them results in the transmission of motion from the first to the second following the coupling of their respective teeth.
  • a diaphragm positioned between the gear and the drum can stop the latter, integral to the threaded rod, from translating under the thrust of the returning spring, towards the gear-motor carrying out the coupling through which the transmission of motion is effected, from the gear to the drum and from here to the threaded rod, on which consequently the slider starts to traslate.
  • Said diaphragm has a large central opening which can only be axially crossed by the drum, when the two radial lobes protruding from the latter on diametrically opposite sides, have taken up an angular position, so as to arrive at two through notches, provided for the purpose along the contour of the central opening of the diaphragm; when this is the case, the two aforementioned lobes cross the notches while the drum moves beyond the opening of the diaphragm.
  • the radial lobes protruding from the drum can assume two different positions, with respect to the diaphragm :
  • the operator only has to activate the geared motor, so as to raise the shutter; when the geared motor rotates it sets the two gears in rotation, which has the effect of making the slider on the first threaded rod, translate; the drum having been manually engaged by the operator by means of the gear-motor.
  • the second threaded rod is not set in rotation in as much as the drum, set in the programming position and working as a free-wheel cannot transmit motion in this direction of rotation.
  • the slider On the first threaded rod the slider also reverses its direction of movement and starts its return stroke which will end exactly when the shutter has reached its bottom dead centre, at the same time as said slider comes to a halt against the limit microswitch, which stops the geared motor.
  • the threaded rod integral to the drum also translates and consequently the slider mounted onto it, comes to a halt against the limit microswitch which stops the motor when the shutter has reached its top dead centre.
  • the slider starts to distance itself from the microswitch, because the threaded rod has started to rotate together with the drum, which has moved from its programming position to a position of total coupling with the gear motor, following the reverse of the geared motor.
  • the device according to the invention comprises two drums with their threaded rods, two diaphragms, two sliders, two limit microswitches, there being specular inverted profiles for the end sections of the teeth of the drums, for the sections of annular track provided on the edges of the diaphragm openings, for the sliders and for the thread of the threaded rods, of which as previously mentioned, one is on the right and the other on the left.
  • the device according to the invention consists of a base (1), on which two parallel threaded rods are mounted (2a and 2b), one on the right and the other on the left, inserted through holes made for the purpose on the sides at the end (1a) of the base (1), said threaded rods (2a and 2b) protruding from the end for a certain length, out of one of the two ends (1a) of the base (1).
  • a central housing (7) On one side of said gears (5a and 5b) is a central housing (7), on the circular surface of which there are a series of grooves (7a), diametrically opposite each other in pairs, within which two ribs (8) are precisely lodged, these ribs running along the external surface of two drums (9a and 9b), inserted on a median knurled section of the threaded rods (2a and 2b).
  • said drums have a circular flange (10), at one end, from which two lobes (11) in a position directly opposite each other protrude, their width being equal to the longitudinal ribs (8) on the same plane as the lobes, said ribs ending at the front in an oblique section.
  • the device according to the invention will be supplied by the manufacturer so that both the sliders are already set to beat against the limit microswitches.
  • the installer engages one of the two drums, say, the one indicated by number 9a, with its gear-motor (5a) and sets the other drum (9b) in its programming position, with its lobes (11) on the tracks (13a and 13b) of the diaphragm (11b).
  • the installer only has to extract the diaphragm (12a) for a short while, so that the drum can rotate until it gets freely inserted within the housing (7) of its gear motor, so that the diaphragm cannot obstruct this manual coupling operation.
  • the installer can activate the geared motor which starts to raise the shutter.
  • the slider (15b) stays at a standstill compared to its supporting rod (2b), while the slider (15a) translates along its threaded rod (2a).
