Definitions

  • the present invention refers to a spring-holder device for rolling gates or rolling doors and to a process for manufacturing such device.
  • This type of device is known in the art and is composed of different types of parts, namely two closing and supporting flanges, two guards that operate as seat for a ring that allows rotating on a rod and a plurality of elements for spacing and joining the two plates.
  • Object of the present invention is solving the above prior art problems, by providing a spring-holder device that can be made of four components only, that, among the other things, are perfecly identical, in pairs, one with the other, highly decreasing the manufacturing costs of the device itself.
  • a further object of the present invention is providing a process for manufacturing the above mentioned device that is completely automated and that allows obtaining the two main components in a single pass, through a consecutive series of progressive forming operations that transform a starting band of plate into the final, complete three-dimensional product.
  • the spring-holder device for rolling gates of the present invention is commonly composed of two protecting and supporting flanges 1 for the rolling gates or rolling doors (not shown) or other products of this type.
  • a suitable guard 3 is obtained, that operates as support and guard for a ring-shaped element 7, usually made in a single piece of plastic material (or operating as rolling bearing), inside which the supporting shaft of rolling gates or rolling doors is placed, that is adapted to rotate inside such ring-shaped element 7.
  • a plurality (usually four) spacers 5 are provided, that keep separated and at the same time join the two flanges 1 in order to obtain between them a space to wind therein the spring of the device that actuates the rolling gates or rolling doors.
  • flange 1, guard 3 and spacers 5 are made in a single piece, adaoted to be coupled with another piece, made in the same way, in order to form the complete device.
  • the step of inserting the ring 7 into the guard 3 can be performed through mechanical means (for example a mechanical arm laterally placed with respect to the line on which the band of material being worked is sliding) for gripping the ring 7 and placing it into the guard 3.
  • mechanical means for example a mechanical arm laterally placed with respect to the line on which the band of material being worked is sliding
  • the step of mutually coupling the flanges 1 is performed by riveting or fastening every respective spacing element 5 with which they are equipped.
