Definitions

  • the present invention relates to a photocell.
  • Photocells which substantially comprise a box-like body constituted by a first half-shell and by a second half-shell which can be mutually coupled.
  • Suitable electric devices which comprise a light source are associated at the first half-shell.
  • the second half-shell has instead a transparent region which allows the light beam to pass.
  • Photocells are known which are used for example to protect a work area, for example road barriers or gate wings or other moving mechanical elements, allowing or preventing the opening of the mechanical element in case of presence of people or objects, in practice monitoring the work area.
  • a photocell which comprises an infrared light source which, in order to protect the work area, can be subjected for example to an adjustment of the light beam on a vertical plane; it is known to arrange inside the photocell, for this purpose, a mirror which by rotating can alter the orientation of the beam.
  • the aim of the present invention is to solve the above-noted drawbacks, eliminating the drawbacks of the cited prior art, by providing a photocell which allows the user to vary the regions to be protected by modifying the orientation of the light beam even after the photocell has been installed, all this being achieved in optimum operating conditions and therefore with constant positioning of the beam even in case of accidental impacts and/or vibrations applied accidentally to the photocell.
  • an object of the present invention is to provide a photocell which has a reduced volume and is therefore structurally compact.
  • Another object of the present invention is to provide a photocell in which the angle that can be given to the light beam can be modified quickly and easily.
  • Another object of the present invention is to provide a photocell which combines with the preceding characteristics that of being reliable and safe in use and of having low manufacturing costs.
  • a photocell which comprises a box-like body constituted by a first half-shell for containing electronic devices and by a second half-shell which has a region which allows the passage of a light beam, characterized in that inside said first half-shell there is a support which is mounted on a first vertical axis and is meant to support a projector or receiver element which is in turn selectively mounted on a second axis which is perpendicular to said first axis.
  • the reference numeral 1 designates the photocell according to the present invention, which comprises a box-like body 2 constituted by a first half-shell 3 and by a second half-shell 4 which can be mutually coupled by means of adapted screws 5 which can be associated, for example, frontally to the second half-shell 4; the stem of the screws can be associated at adapted first seats formed in a first half-shell 3.
  • connection between the first half-shell and the second half-shell can furthermore be facilitated by the presence of adapted tabs 7 which protrude therefrom along its perimeter and are substantially L-shaped, with a free end which can be inserted at complementarily shaped second seats 8 formed inside the second half-shell 4.
  • Suitable electronic devices 9, such as for example electronic circuits, can be arranged within the first half-shell 3; a supporting wing 10 further protrudes toward the second half-shell 4 proximate to the upper end of the first half-shell 3 and supports a light source such as a projector element or a receiver element, designated by the reference numeral 11; the projector element can be constituted by an infrared light source, while the receiver element can be constituted by a receiver for an optical signal.
  • a substantially C-shaped fork 13 is pivoted at right angles to the wing 10 and therefore at a first axis 12; its second wings 14a and 14b are directed away from the wing 10.
  • the light source 11 is rotatably associated between the second wings 14a and 14b and rotates at a second axis 15 which is perpendicular to the first axis 12.
  • Such rotation can be set selectively by the user, since means are provided which are suitable to discriminate the angular arrangement of the photocell; said means are constituted by suitable sets of teeth 16 and complementary sets of teeth 17 which protrude respectively from the lateral surfaces of the light source 11 and from the internal lateral surfaces of the second wings 14a and 14b of the fork 13.
  • a semitransparent region 18 is formed at the light source 11 at the second half-shell 4 and is adapted to allow the passage of the light beam.
  • the invention has achieved the intended aim and objects, a photocell having been provided which can be installed and therefore positioned without special care, since the light beam can be positioned rapidly and in an optimum manner by the operator by turning the fork 13 in order to orientate it on a horizontal plane and by turning the light source 11 in order to orientate it on a vertical plane.
  • the presence of the complementary set of teeth 17 and of the set of teeth 16 further allows to stably select the arrangement of the light source 11 on the vertical plane, thus making the photocell free from malfunctions caused by vibrations and/or accidental impacts.
  • the resulting photocell is furthermore merely very compact as well as reliable and safe in use and has low associated costs.
