Definitions

  • the present invention relates to a closure device particularly for closing doors in vans, containers freezer cars and the like, capable of giving to the doors maximum stability in closure, regardless of the type and the direction of the stresses to which said closure is subject during the movement of the vehicle.
  • hook-like couplers which provide a rib or protrusion, substantially in the shape of a truncated cone, at the end opposite to the one which bears the coupling forks and axially thereto.
  • the rib accommodates in a complementarily shaped seat provided in the coupler plate; this prevents the fork in closure from moving transversely with respect to the rotatable rod and therefore allows to oppose any stresses occurring transversely with respect to the shutters, ensuring a stable closure in this direction.
  • couplers are not capable of opposing all the other previously mentioned stresses to which the clamp is subject during movement and which jeopardize the stability of the clamp itself.
  • the aim of the present invention is to provide a closure device particularly for closing doors in vans, containers, freezer cars and the like, capable to eliminate the disadvantages and shortcomings of known devices, and most of all such as to be capable, once the coupling has occurred, of recovering any elastic deformation of the door-frame/shutter assembly and of opposing with maximum effectiveness the various stresses to which the closure is normally subject during the movement of a vehicle on the road, as, for example, of a ship during seafaring transportation.
  • a further object of the invention is to provide a structurally simple and highly reliable door closure device, easily operated in closing and in opening, as well as adapted to be provided even with two or more closure rods for two shutters according to the loads and to the stability and safety requirements.
  • figure 1 is a schematic front view of the component elements of an ordinary closure for doors of containers and the like;
  • figure 2 is a side view of a hook according to the invention, separated from the rotatable operating rod;
  • figure 3 is a front view of the hook of figure 2;
  • figure 4 is a top view of the hook of figure 2 according to the line A-A of figure 2;
  • figure 5 is a cross section view along the line B-B of figure 2;
  • figure 6 is a front view of the coupler element for the hook of figure 2;
  • figure 7 is a top view of the coupler element of figure 6;
  • FIGS 8 and 9 are two cross section views respectively taken along the lines VIII-VIII and IX-IX of Figure 6;
  • figure 10 is a view of the positions of the hook of figure 2 approaching the coupler element of figures 6 and 7;
  • figure 11 is a front view of the completed insertion of the fork of the hook in the related coupler.
  • figure 12 is a middle cross section view of the insertion of figure 11.
  • an ordinary clamp for doors or shutters of vans and the like is composed of at least one rod 1, usually tubular at least at its extremities, which is mounted vertically and rotatably on the outer face of a door and, in the case of a two-shutter door, at the region of overlapping and mating of one shutter with the other; the rod 1 is rotatably supported by end brackets 2 and by intermediate brackets 3.
  • a rod-like handle 5 is hinged perpendicular to the rod at a pivot 4 for rotating the shutter. The handle 5, when the shutter has been closed, is rotatable until it reaches the position 5a illustrated in phantom lines and is lockable in an adapted seat 6 by means of a lock 7 or the like.
  • the hook means intended to insert in couplers rigidly associated with the frame of the door opening of the van or of the container are rigidly associated with the two ends 1a of the rod 1, and substantially form the object of the present invention and will be described in detail hereinafter with reference to figures 2 to 12.
  • the closure device comprises a hook to be welded to the ends of the rod 1 and a coupler element to be connected, by welding or bolting, to the frame (above and below it) of the door opening of the vehicle, said door opening not being illustrated in the figures.
  • the hook is constituted by a substantially T-shaped element, generally indicated by 8 in figure 2, having a vertical portion 9 which inserts into the ends 1a of the rotatable tubular rod 1; an intermediate flange 9a provides an abutment against the end bracket 2.
  • the horizontal part 10 of the T-shaped element constitutes instead the hooking and insertion element.
  • this hooking element 10 is made in the shape of a fork 10c, the prongs 10a-10b whereof are provided at their ends with two teeth, or tips, 11-11a which are outwardly curved with respect to the door plane (figures 2-3), that is to say located at the end of a holder 12 (figure 4).
  • the horizontal part 10 of the T-shaped element is longitudinally splined for its entire length so as to form a continuous groove 13 having a substantially conical cross section; said groove is open at the end 14 opposite to the fork end; the end 14 being curved and connected to a lower inclined plane 15 for reasons which will become apparent hereinafter.
  • FIG. 5 illustrates a cross section of the horizontal part 10 along the line B-B of figure 2.
  • the coupler element adapted to cooperate with the above described hook, comprises a plate-like element 16 (figures 6 and 7) provided with means for being fixed to the door-frame of the vehicle, such as, for example, bolts inserted in the holes 17 or welding.
  • An enlarged portion, forming a continuous rib 18 having a substantially conical cross section, as clearly illustrated in figure 9, is rigidly associated with said plate 16 and its size is such as to mate with the continuous groove 13 provided longitudinally in the hook 8.
  • a double lug transverse element 19 is provided at one end of said rib 18, while a heel or protruding abutment 20 (figure 7), against which the planar end 15 of the hook rests once the coupling has occurred, is provided at the other end.
  • the double lug transverse element 19 is of a substantially cylindrical shape having ends which protrude above and below the rib 18.
  • the abutment 20 extends toward the end of the rib 18 having attached thereto the double lug 19 to thereby define an acute angle between the extension of the plate like element 16 and the extension of the abutment 20.
  • the closure device operates as follows (figure 10):
  • the door is turned on its hinges along the radius of rotation R so that the hooks 8 pass from position 8 to position 8a etc., until the teeth 11-11a of the fork of the hook make contact with the double lug element 19; at the moment of the first contact 19a between the teeth and the double lug element, by reversing the direction of rotation of the rod 1 the hook and the coupler begin to engage since the fork tips, by resting on the lugs, act as levers, forcing the longitudinal groove of the hook to gradually accommodate the rib of the plate 16 until, when the coupling has occurred, the end 15 of the hook rests against the heel 20.
  • the double lug is engaged at the maximum possible distance and thus the shutter is "pulled" into the door-frame, facilitating the insertion of perimetral gaskets made of rubber or the like.
