Definitions

  • the present invention relates to a device for anchoring the free end of a chain of a chain-type actuator to a shutter.
  • Chain-type actuators are currently known and widespread which allow the automatic opening and closing of shutters, especially of shutters located in positions that are difficult to reach, such as for example skylights of a gymnasium or of an industrial building.
  • These actuators comprise, within a box-like container that is fixed to the frame of the casing related to the shutter, a chain that is guided so as to slide by guiding elements within a preset path that leads outside through an opening in such box-like container.
  • the chain is of the type that can flex only in one direction and is prevented from flexing in the opposite direction.
  • the chain has a free end that is associated with a device for anchoring to the corresponding shutter, which is composed of an engagement terminal, jointly fixed to the free end of the flexible element, and a complementary engagement block, associable with the engagement terminal, jointly fixed to the shutter.
  • the engagement terminal has, transversely to the direction of action of the chain, mutually opposite protrusions for mating with complementary holes formed in two mutually opposite elastically deformable wings that belong to the engagement block that is fixed to the shutter.
  • the engagement block also comprises an outer shell, which covers the C-shaped lamina and interlocks reversibly with such wings.
  • Such outer shell is also C-shaped, so as to form a central recess for accommodating the engagement terminal.
  • the shell has access openings for the protrusions for mating the engagement terminal to such holes.
  • Insertion of the engagement terminal occurs by lateral elastic deformation of the wings and insertion of the protrusions of the terminal in the respective holes in the wings.
  • the elastically deformable wings return to the original position.
  • the ends of the wings have an outward fold and can be accessed from outside the shell through such openings, so that even with a simple punching tool or screwdriver it is possible to act on the fold, flex the wing and disengage the terminal.
  • the locking of the terminal with respect to the block occurs easily by inserting a punching tool or the head of a screwdriver in one of the openings in order to press outward the corresponding fold at the end of the corresponding wing.
  • the main aspect that can be improved is the relative complexity of the engagement block, which as mentioned comprises a C-shaped metallic lamina that must be provided by means of a sequence of operations for pressing and bending a metal plate, which require a certain time and a certain labour, in addition to the cost of the raw material.
  • a covering shell made of plastics is associated with the C-shaped metallic lamina and must be fitted on the lamina after it has been fixed to the casing. Further, the disengagement of the terminal from the block requires intervention on the part of an operator with a pointed tool, in order to flex a wing of the C-shaped lamina so as to free a protrusion of the terminal, as described above, Disclosure of the Invention
