Definitions

  • the present invention relates to a contactless security device, particularly for motorized vertical sliding closing systems.
  • the doors of the aforementioned type are usually driven along guidance rails and, for their vertical movements between the open and closed positions, they can be controlled by an electric gear motor which can be activated by means of a remote control or by other means, such as a proximity sensor, key devices, push buttons or the like.
  • each of said doors is usually provided, along its lower horizontal edge, with a system capable of detecting the presence of bodies or obstacles on the trajectory of movement and then cause an automatic stop of the door itself.
  • Such a system can comprise means such as a so-called sensitive edge, infrared optical barriers or the like which, however, are activated and intervene to stop the door only when it physically encounters an obstacle, a condition that can still be dangerous and harmful if the obstacle is represented by a child, an animal or a fragile and delicate thing, due to the pressure exerted by the door before it stops.
  • the sensitive edge or presence sensors as set up so far, can be ineffective when the lower edge of the door is not in the vertical sliding plane and is therefore not exactly perpendicular to the obstacle, as can happen, e.g., with a vehicle that, being high, can interfere with the lower edge of the moving door when it starts to move from the open to the closed position.
  • a contactless security device is known from patent EP2273051B1 provided with two security units, which are applied to the inner face of the door, at its lower side adjacent to the lateral edges.
  • the security units are provided with transmitter and receiver photocells, defined on sliders which slide horizontally and vertically so as to bring the optical barrier below the lower side of the door.
  • This latter type of contactless security device is also subject to further upgrading.
  • this latter type of contactless security device ensures the automatic stop only when obstacles are detected in the area wherein the optical barrier is defined.
  • the main aim of the present invention is to devise a contactless security device, particularly for motorized vertical sliding closing systems which is able to guarantee automatic stop in the event of obstacle detection, for the entire width of the door.
  • Another object of the present invention is to devise a contactless security device, particularly for motorized vertical sliding closing systems which is particularly simple, efficient and reliable, and capable of positioning itself in a work configuration by its own gravity and of withdrawing to a home configuration through a composite, substantially vertical movement when the door reaches the closed position.
  • Another object of the present invention is to devise a security device for the type of door mentioned above and capable of perfectly positioning itself in the sliding plane of the door, at the base of the latter, and of detecting obstacles at any level within the range of the door closing stroke and cause it to stop automatically if obstacles are detected.
  • Another object of the present invention is to devise a contactless security device, particularly for motorized vertical sliding closing systems, which allows overcoming the aforementioned drawbacks of the prior art in the ambit of a simple, rational, easy, effective to use and low-cost solution.
  • reference numeral 1 globally indicates a contactless security device, particularly for motorized vertical sliding closing systems.
  • the device 1 is intended to be fitted to a movable motorized door 2 along lateral guides 3 for sliding between at least one closed position, wherein a lower side 4 of the motorized door 2 is adjacent to an underlying floor, and at least one open position, wherein the lower side 4 is moved away from the floor.

  • the optical barrier means 10 comprise one emitter 12, associated with one of the sliders 8, and at least one receiver 13, associated with the other of the sliders 8 and substantially in line with the emitter 12.
  • the optical barrier 11 has the function of blocking the movement of the motorized door 2 in the presence of an obstacle B.
  • the sliders 8, each supporting the emitter 12 and the receiver 13, respectively, are adapted to move the aforementioned optical barrier 11 with respect to the lower side 4 of the motorized door 2, and each slider 8 is susceptible of combined horizontal and vertical translation movements, with respect to the supporting element 6.
  • each supporting element 6 comprises two parallel vertical walls 14, each provided with at least two guiding slots 7 arranged on two different levels.
  • Each guiding slot 7 has a lower portion 15 inclined away from the internal face of the motorized door 2 in the direction from bottom to top, followed by an upper vertical portion 16.
  • each slider 8 has at least two pairs of sliding pins 9, each individually driven in each guiding slot 7.
  • each slider 8 is substantially rectangular in shape and has two long sides opposite each other.
  • the pairs of sliding pins 9 are defined on the aforementioned long sides, in an upper part of the slider 8, while the optical barrier means 10 are associated with a lower part of the slider 8 itself.

  • the sliders 8 are moved closer with respect to the sliding plane of the motorized door 2, while in the home configuration they are moved away from it.
  • each slider 8 also comprises at least one roller 17 resting on the floor which is rotatable around a horizontal axis substantially parallel to the lower side 4 of the motorized door 2 itself.
  • the latter is adapted to facilitate the movement of the slider 8 when the motorized door 2 is moved towards the closed position, in the proximity of the floor.
  • the optical barrier means 10, defined on an internal surface of the slider 8, facing the motorized door 2 are positioned below the lower side 4, in the sliding plane of the motorized door 2, during its entire opening and closing stroke.
  • the receiver 13 and the emitter 12 are associated with the sliders 8 by interposition of corresponding supporting units 18 rotatable around corresponding axes of rotation A.
  • the axes of rotation A are substantially orthogonal to the sliding plane of the motorized door 2.
  • the device 1 comprises at least two security elements 19 which are respectively associated with the supporting units 18 and which extend to the second areas Z2 of the sliding plane of the motorized door 2, comprised between the security units 5 and the lateral guides 3.
  • the security elements 19 are adapted to set the supporting units 18 in rotation and, consequently, the emitter and the receiver 13 around the axes of rotation A and thus to interrupt the optical barrier 11.
  • the security elements 19 conveniently comprise at least one bar 20 provided with a first end 21 associated with the supporting unit 18 and a free second end 22 arranged in the proximity of a respective lateral guide 3.
  • each security element 19 extends along at least a first longitudinal direction and is movable between at least a first position, wherein the aforementioned first direction is horizontal and the receiver 13 and the emitter 12 are aligned with each other to define the optical barrier 11, and at least a second position, wherein the aforementioned first direction is inclined and the receiver 13 and the emitter 12 are misaligned with each other to interrupt the optical barrier 11.
  • the security elements 19 have such a conformation that they are made to rotate, together with their respective supporting units 18, upwards, once an obstacle B, present inside the second areas Z2, has been found.
  • the security elements 19 are made of a metallic material, characterized by such a weight that it facilitates the aforementioned rotation downwards.
  • each security element 19 and the respective supporting unit 18 are made of separate bodies assembled to each other.
  • each security element 19 and the respective supporting unit 18 can be made in a single monolithic body.
  • each slider 8 comprises at least one abutment element 23 adapted to come into contact with at least one of either the supporting units 18 or the security elements 19, with the latter in the first position, and to block the rotation thereof around the axes of rotation A.
  • the operation of the present device 1 is as follows.
  • the device 1 performs its main function during the sliding of the motorized door 2, onto which it is applied, from the open position to the closed position.
  • the sliders 8 of the security units 5 are in the lowered position, in their work configuration, wherein they tend to place the optical barrier means 10 below the lower side 4 of the motorized door 2 and along its sliding plane, and the security elements 19 are in the first position.
  • the optical barrier 11 is defined in the first area Z1, comprised between the two security units 5.
  • the security elements 19 are arranged horizontally, in extension in the second areas Z2, between the security units 5 and in the proximity of the respective lateral guides 3.
