Definitions

  • the present invention concerns in general the up-and-over doors and more particularly, although not exclusively, doors for closing private and common car garages and the like, also called motorized passages.
  • the invention concerns more precisely an up-and-over door assembly comprising a rigid (one-piece) door, restrained to a frame which in turn is secured to the structure to be closed, and movable around a horizontal axis from a vertical closed position to an open position in which the is lifted and lies in a substantially horizontal plane position.
  • the doors of this type provide for a driving motor and means for detecting the presence of an obstacle during the closing of the door, cooperating with a control unit to interrupt its movement in presence of an obstacle.
  • EP 1229200 discloses an up-and-over door assembly comprising a one-piece door restrained to a three-dimensional frame comprising a pair of vertical guides and a pair of horizontal guides arranged so that the door never projects outside of the plane defined by the vertical portion of the frame.
  • deformable edges are applied along the side edges of the door, each comprising a pair of elongated conductors that are short-circuited by the deformation casused by the presence of an obstacle.
  • a pair of aligned IR transmitter and receiver devices and the short-circuit of the deformable edges obscurates the IR beam and therefore stops the movement of the door.
  • pairs of lined up IR transmitter-detector forming so-called contactless barriers are provided along the door lower edge and at least partially along the door side edges.
  • an up-and-over door assembly includes a single-leaf panel 4 hereinbelow referred to as "door”, and a frame 10, fixed to the structure by to be closed and formed by two upright members 1, 2 connected at their upper ends by a horizontal crossbeam.
  • the door 4 is monolithic, that is formed by a single piece and relatively rigid (i.e. it is not formed by hinged elements as in the sectional doors).
  • elongated guides 5 (one shown in Fig. 1 ) within which pins, rolls or the like, fixed to the door 4 can slide in the opening-closing movements.
  • the door 4 vertically rotates around a movable horizontal axis so as to positioning itself in the open position near the crossbeam 3 with a substantially horizontal lying as shown in Fig. 1 .
  • the door protrudes from the vertical plane defined by the frame 10, or better by the uprights 1, 2 and the crossbeam 3.
  • the door 4 With a reverse movement the door 4 reaches a closed position (not shown) in which it is vertically disposed without projecting from the above mentioned vertical plane defined by the frame 10, i.e. the uprights 1, 2 and the crossbeam 3.
  • the safety device includes three pairs of IR transmitter-receiver indicated with TX and RX respectively, and a control unit 12 adapted to receive signals representative of the state of the beams and to control a motor (not shown) for carrying out the closing and the opening of the door.
  • the components TX and RX comprise casings of plastic material, hereinbelow shortly indicated as “turrets", that house said transmitters and/or receivers. A preferred embodiment of such turrets will be described later with more details.
  • a pair of turrets housing the transmitter TXb and the receiver RXb are fitted to the lower edge of the door 4, the one abutting against a ledge when the door is closed, and are preferably located at the lower corners of the up-and-over door, so that the infrared beam 15 emitted by the transmitter TXb and received by the receiver RXb extends in a space immediately adjacent to the lower edge of the door, at a distance of 2-5 cm from it.
  • a similar pair of transmitter-receivers is positioned on each side edge of the door 4, indicated by TXD, RXD and TXS, RXS, respectively, that produces two infrared beams, respectively 16 and 17, parallel and running at a distance of 2-5 cm from the door side edges.
  • the side beams 16, 17 extend only along the door edge portion susceptible of contacting obstacles and not along the whole side edge of the door.
  • the IR transmitters and receivers are advantageously housed inside casings or containers of a plastic material, that can be secured to the door by means of screws or the like.
  • Fig. 3 shows an embodiment of one of such turrets comprising a plastic container 30 formed by two members or parts that can be partially inserted one into the other.
  • the turret houses an infrared transmitter and an infrared receiver TX and RX, typically a transmitter (or emitter) of infrared radiation, such as an IR source and a receiver (sensor) of infrared radiation, such as a photocell.
  • the container 30 is equipped with means 34, 35 for focusing the infrared beam, typically in form of two lenses with their axes forming a 90° angle, for concentrating the transmitted or received beams.
  • the turret further provides for two seats 31, 32 also arranged at 90° to one another, for receiving the ends of elongated rubber members to minimize the effect of a possible impact against an obstacle.
  • the infrared sensor of the receiver RX generates a signal upon receiving the beam coming from the aligned transmitter, and doesn't generate any signal in case the beam is obscured or interrupted by an obstacle during the closing of the door.
  • Such means can be connected to the control unit 12, or be incorporated in the same.
  • such means can include logical devices that produce a signal when the receiver receives the beam and the corresponding transmitter is contemporarily operating (in order to avoid false command signals due to a faulty transmitter).
  • each turret when using a turret 30 such as the one illustrated in Fig. 3 , each turret advantageously houses a transmitter and a receiver operating (directed) along two orthogonal directions, thus making the construction of the assembly quite simpler.
  • the side turrets TXS and TXD that are not positioned at the door corners can have a simpler construction since each of them has to contain only one transmitter.
  • turrets as shown in Fig. 3 can be employed, but housing only a pair of receiver - transmitter, or leaving inactive (not connected) the second pair.
  • the side edges and the lower edge of the door are further provided with elongated rubber profiles, indicated in Fig. 4 by references 20, 22 and 21, respectively. They extend in a continuous or discontinuous way, to minimize the effect of a possible impact of the door against the body of a person that has interrupted the beam.
  • the control unit 12 is preferably mounted near one of the turrets of the door lower edge to simplify the assembling and the maintenance, but its position is by no means critical.
  • the signals representative of the continuity of the beams reach the unit 12, and the closing of the door is stopped when there is detected an interruption of any one of the three beams. Under these circumstances the unit 12 causes not only the stopping of the door but also an inversion of the door movement (i.e. an opening movement) practically without any impact with the obstacle.
  • the control unit is capable to arrest the driving motor and to reverse its rotation when the presence of an obstacle interrupting at least one of the three beams is detected.
