  • the obstacle detector of the invention is based on electrically monitoring the relative position of a freely rotating latch that travels loosely between a head of the input shaft and a contact bushing attached to the output shaft.

  • a centering shaft (7) In the center of the input shaft (2) there is a centering shaft (7), which allows you to perfectly align an output shaft (8), supported by bearings (9) in an outer housing (10) integral with the tube (1) . See figure 1.
  • the latch (11) is located, with rotating clearance, between an input shaft head (19) and a contact bushing (21) attached to the output shaft (8) with interposition of a bushing insulator (22), arranged in a housing of the contact bush (21) a second contact (23) loaded by a second spring (24) in such a way that it rests on the outer race (6).
  • the output shaft (8) also has, in correspondence with the input shaft head (19), an output shaft head (25).
  • the operation of the device is as follows. During the closing maneuver, the output shaft (8) tends to move spontaneously due to the weight of the closing device itself, so that the head of the output shaft (25) will be retained by the head of the input shaft (19) moving both with a speed determined by the latter.

(twenty-one). See figure 12. If during a closing maneuver, the device encounters an obstacle in its path, the head of the output shaft head (25) will be stopped. However, the head of the input shaft (19) will continue to move and drag the latch (11) until it rests on the contact bushing (21), closing the detection switch of the external electrical circuit (4). The relative movement that occurs between the latch (11) and the contact bushing (21) is possible thanks to the sliding of the magnets (14) on the retention stop (15). See figure 13.

  • the head of the input shaft (19) drags the head of the output shaft (25) and the latch (11) that remains supported on the contact bushing (21). Note the differences in the position of the latch (11) between a normal opening maneuver (figure 12) and an opening maneuver subsequent to the detection of an obstacle (figure 14). In this way, the closing of the detection switch is assured until the end of the opening maneuver, in which a limit switch releases the auxiliary relay.
  • the overall effect is that opening and closing maneuvers can be performed in the usual way, but if an obstacle is encountered during a closing maneuver, the automatic reversal of the direction of movement will occur.
  • the detection device of the invention is based on monitoring the relative position of a latch (11) retained by frictional forces.
  • the set constitutes a virtual detection switch. It is evident that if the different elements are metallic, we must insulate both the latch (11) and the contact bushing (21), which is achieved by means of a latch insulator (20) and a bushing insulator (22).
  • the input count (3) and its contact tracks (5) (6) are only intended to transmit the electrical situation of the mobile elements to the external, fixed electrical circuit.
  • the contacts (12) (23) are magnetized, in order to ensure electrical continuity with the tracks (5) (6), which greatly improves the reliability of the device by suppressing possible mechanical bounces induced by the springs (13) (24).
