Definitions

  • the present invention relates to a tube for connection to the actuation handle and to the corresponding end of a swivel bolt for closing wings of doors of trucks, trailers or the like.
  • tubes having a circular cross-section for connection to the actuation handle and to corresponding ends of two swivel bolts, an upper one and a lower one, for closing wings of doors of trucks, trailers or the like: such tubes have some drawbacks in relation to their coupling to the swivel bolts and swiveling actuation handle, which usually occurs by welding to the two bolts and by means of diametrical pins or welding as regards coupling the manual grip handle to the tube; this entails a considerable waste of time and the need to use welding units or the like in order to assemble the components.
  • the aim of the present invention is to obviate the above-cited drawbacks and meet the mentioned needs, i.e., to provide a tube for connection to the actuation handle and to the corresponding end of a swivel bolt end for closing wings of doors of trucks, trailers or the like which can be assembled easily and rapidly without requiring particular accuracy or welding or the like.
  • an object of the present invention is to provide a tube which is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
  • the present tube for connection to the actuation handle and to the corresponding end of a swivel bolt for closing wings of doors of trucks, trailers or the like, characterized in that the tube and the end of the swivel bolt have complementary cross-sections shaped like polygons having convex sides.
  • the reference numeral 1 generally designates a tube for connection to the actuation handle M and to the corresponding end 2 of a swivel bolt 3 for closing wings of doors of trucks, trailers or the like according to the invention.
  • the tube 1 and the end 2 of the swivel bolt have complementary cross-sections which are shaped like a regular polygon, particularly like a triangle having three slightly convex sides 4; the end 2 substantially forms a coupling tang with preferably curved surfaces and a slightly rounded tip 2a.
  • Figures 1 and 4 illustrate two alternative and preferred embodiments of the rotary coupling of the bolt 3 to a corresponding support 5.
  • the support 5 is advantageously formed by two portions 6 and 7 (as illustrated in Figure 3) made of stamped metal plate (or aluminum section), respectively a lower portion and an upper portion, which are crossed by corresponding holes 8 for fixing to the wing.
  • a cylindrical seat 9 for the rotation of the stem 10 of the bolt is formed between the portions 6 and 7 in a central position.
  • an intermediate region 10a of the stem 10 comprised between two annular raised portions 11 and 12 of the stem (known in the field as "anti-rack ridges") is placed between the portions 6 and 7: in this embodiment, two bushes 13 and 14 are fitted between the inlets of the seat 9 and the region 10a of the stem, and each bush is constituted by two bush portions advantageously made of a material such as bronze coated with PTFE.
  • the stem 10 has a single raised portion 15 and in the portions 6 and 7 there are two complementary recesses 16 and 17 for centering the raised portion 15 and two complementary recesses 18 and 19 for centering a bush 20 which is advantageously made of synthetic materials of the type known by the tradename Nylon.
  • the bush 20 has an internal hole, whose cross-section is shaped like an equilateral triangle with slightly convex sides so as to mate with the outer surface of the tube 1, and is externally cylindrical so as to be arranged rotatably in the recesses 18 and 19.
  • a similar bush 21 provides the coupling to the box S of the handle M; the handle is crossed by a hole F which is substantially identical to the external cross-section of the tube and requires no welding or pins.
  • the tube 1 can have a different cross-section than the one shown and its external cross-section need not be the same as its internal one (for example, it might be triangular externally and square internally).
  • the operation of the invention is self-evident: in order to couple the tube 1 to the end 2 it is sufficient to fit it, after cutting it to size, on the tip of the end 2 and fit the upper portion 7 of the support 5; any small differences in the length of the tube 1 are compensated by possible small relative movements of the tube 1 and the end 2.
  • the tube 1 serves only to transmit the rotation to the pawls and has no other functions for vertical support of said pawls: assembly is simplified, since the fitter (differently from what occurs instead with conventional rods) is practically forced to leave no play between the anti-rack washers and the supports 5.
  • the invention achieves the intended aim and object, and in particular that it provides a tube for connection to the actuation handle and to the corresponding end of a swivel bolt for closing wings of doors of trucks, trailers or the like which can be assembled easily and rapidly without requiring particular accuracy or welding or the like.
  • the tube can have a hexagonal, square, oval or other cross-section and the outer cross-section can be different from the inner one.
