Definitions

  • the present invention relates to a collapsible or extensible gate, including built-in anti-theft means, and also relates to a method for making this gate.
  • gates which are generally formed by metal section member uprights which are connected to one another by scissors crossing rods allowing the uprights to be displaced with respect to one another, the uprights being guided, in their displacements, by a top rail and a bottom rail.
  • the mentioned uprights are made starting from a pair of C-shape section members which are opposite to one another and connected by pivot pins, engaging in holes formed on a central portion of the section member and upset so as to provide a firm coupling.
  • the heads of the rivets project from the section member bodies, and these heads can be easily cut-off by using a chisel and a hammer, thereby providing a poor protection against possible thefts.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a collapsible or extensible gate, including antitheft means, for door or window frames in general, which does not include any pins or rivets to be applied by means of mechanical operations and which, as stated, can be easily removed by cutting.
  • a main object of the present invention is to provide such a collapsible gate for window and door frames which can be automatically made, so as to greatly reduce its making cost.
  • Yet another object of the present invention is to provide such a collapsible gate which, being devoid of any projecting rivet heads, has a very improved aesthetic configuration, while providing a very safe and reliable operation.
  • a collapsible gate including built-in antitheft means, for door and window frames in general, comprising a plurality of uprights engaged at respective end portions thereof with a top guide rail and a bottom guide rail, said uprights being movably connected to one another by crossing scissors rods, characterized in that each of said uprights comprises a pair of C-shape section members, opposite to one another and connected by fixing pin elements which are welded, at respective end portions thereof, to an inner surface of a central portion of the C-shape section members, at least a portion of said pin elements defining an articulation fulcrum for said rods.
  • the collapsible or extensible gate including built-in antitheft means, for window and door frames in general, according to the present invention, which has been generally indicated at the reference number 1, comprises, in a known manner, a plurality of uprights 2 which are connected to one another by means of a plurality of connecting rods 3, which are scissors-like pivoted to one another, so as to allow the several uprights to be displaced.
  • the uprights 2 are engaged, at their end portions, respectively with a top guide section member 5 and a bottom guide section member 6.
  • each upright is constituted by a pair of C-shape section members, indicated respectvely at 10 and 11, which are opposite to one another.
  • section members 10 and 11 are connected by means of pin elements 20, which are welded to the inner surface of the central portion 12 of each section member, so that these connecting elements do not present outwardly extending projections.
  • pivot elements 20 welded to the inside of the section members 10 and 11, are provided for forming the articulation fulcrum region for the middle portion of the rods 3, which, at their end portions, are connected by means of pin elements 21 which are slidably guided inside the C-shape section member.
  • the uprights 2 engage with a top guide rail.
  • the head portion of the pin element 20 is welded by means of an electric discharge and, to this end, the pin elements 20, as is shown in Figure 2, will be provided with lugs 20a adapted to facilitate the welding operation.
  • the other section member 11 After having applied the rods and pins, as well as the small trucks, the other section member 11 is applied, by performing, by means of a welding head 45, the welding of the ends of the pin elements 20 facing the section member 11 so as to properly assemble the uprights, without any projecting portions.
  • collapsible gate owing to its fully automatic making method, can be made with a very reduced making cost.
