Definitions

  • the present invention relates to an access panel for a pole.
  • an opening is formed at a certain easily reachable height of the pole, which allows access to the inside where a terminal strip with associated accessories for connecting the electric components is accommodated;
  • said opening usually has a vertically elongated rectangular shape with semicircular short sides, and said opening is closed with an access panel which is fixed by acting on, two or more screws for coupling to the pole: coupling is achieved by screwing the screws into internal anchors which, through of the screwing action, clamp the edge of the opening.
  • the coupling of the access panel to the pole is of course hermetic to prevent water from entering the pole and reaching the terminal strip.
  • pole fixing screws can be actuated with conventional screwdrivers or with screwdrivers with a cross-shaped or star-shaped head or with hexagonal profiles which are easily available and can be replaced with makeshift tools which allow vandals, children or the like to open the access panel.
  • the technical aim of the present invention is to obviate the above-cited drawbacks of conventional devices, i.e., to provide an access panel for poles which has a profile with no external elements or edges, has simplified anchors which do not require add-on springs and nuts, has optimum watertightness and in which the fixing screws cannot be operated without a specific tool supplied with the access panel and not commercially available.
  • an object of the present invention is to achieve the intended aim with a structure which is simple, relatively easy to provide in practice, safe in use, effective in operation and relatively low in cost.
  • the reference numeral 1 generally designates an access panel for poles P according to the invention.
  • the access panel 1 is constituted by a vertically elongated shell 2 formed by pressing rustproof metal alloys: the shell 2 is shaped so as to have a substantially cylindrical profile which wraps around the pole, has a rectangular and vertically elongated shape in which the shorter side 3a and 3b are semicircular, is peripherally provided, toward the outside, with a smoothly rounded edge 4 and has absolutely no parts that protrude toward the outside of the profile.
  • the shell 2 is externally provided, proximate to its ends, with two recessed seats 5 and 6 which are crossed by respective through holes 7 for the snap insertion of rustproof retention bushings 8 made of a thermoplastic material;
  • the bushings 8 have a portion 9 which has a larger diameter, with a recess 10 for the head 11 of an effraction-resistant screw 12; said recess is provided, along its perimeter, with three spaced teeth 13 for retaining the head of the screw;
  • the bushings 8 have a portion 14 which has a reduced diameter, is crossed by a hole 15 for the stem of the screw 12, is externally provided, at its end, with an annular raised portion 16 for snap coupling in the through holes 7 of the recessed seats 5 and 6, and is longitudinally provided with three notches 17 which allow its deformation for coupling to the shell 2.
  • an axial symmetrical cavity 18 with three sides 19, each of which is cylindrical, has its concavity directed toward the axis of the screw and its radius of curvature arranged so as to coincide with the mutually opposite vertex: in this manner it is impossible to operate the screw with a screwdriver or with tools which are commercially available; if they are inserted, such tools merely turn idly by pivoting in succession on the various edges; any attempt at actuation with improper tools is further ineffective.
  • the screws screw into substantially central threaded holes 20 of two corresponding shaped brackets 21, respectively an upper one and a lower one, which are perpendicular to the screw and are designed for coupling to the pole:
  • the shaped brackets 21 are obtained by die-pressing high-strength materials, such as steel, and have a portion 21a which is directed toward the center of the shell, is folded toward the outside of the pole and is shaped like a fork 22 for nonrotational coupling to a corresponding pin 23 located inside the shell.
  • the bracket On the other portion 21b, the bracket has two complementary lateral folds 24 for adapting to the internal profile of the pole P in order to eliminate the possibility of unauthorized extraction and/or removal.
  • the shell 2 is internally provided with a pair of symmetrical pins 25 and 26 which are adapted to center the access panel in the slot 27 of the pole P and to prevent it from sliding downward during the operations for mounting on the pole.
  • the shell is peripherally provided, toward the pole, with a perimetric channel 28 for a gasket 29 made of a material such as rubber, which has a substantially elliptical cross-section; the channel 28 is provided with sets of staggered teeth 30a, 30b, 31 distributed on its two facing sides in order to retain the gasket in the access panel.
  • a threaded seat 32 for a screw for electrical connection to the ground is provided inside the access panel.
