Definitions

  • the present invention relates to a pair of lids for containers of urban residues especially specifically for large containers therein, which are independently used by the user.
  • the object of the invention is to achieve considerable simplification of the damping means, which facilitates the container assembly, as well as greater stability for the lids when closed.
  • one or more gas cylinders are used, variable in number depending on the characteristics of the cylinders and on the container dimensions, which are established between both lids.
  • one of the ends of the gas spring is articulately joined to one of the lids, whilst the other end does so to the second lid, so that it is necessary to establish two forks, one on each lid, and implant and fix transversal pins in said forks as trunnion axes for the ends of the gas spring, which considerably complicate the assembly thereof.
  • a solution in this line is that shown by document DE-U-70 12 526 , corresponding to the preamble of claim 1, where the container lid has one lug and the opening of its body another, establishing between them a gas cylinder which acts as buffer in the gravitational lowering of the lid towards its closed position.
  • a gas cylinder is also used in document DE-A-3033 298 , in this case established between the side walls of the container body and a rod also articulated to said body, so that said rod acts as an arm counteracting the gas cylinder, on a U-shaped piece solidly joined to the lid, so that said buffer tends to keep the lid open or to keep it closed, by its position on one or another side of an intermediate dead point.
  • This document only partially resolves the problem posed, since the lid tends to stay open, in a partial open position, and it is necessary to have the participation of a person to carry out the definitive closing thereof, and in said definitive closure manoeuvre occurs the impact of the lid on the body, which although less than that which occurs with free fall of said lid, it is considerably noisy.
  • said cylinders are articulately joined to just one of the lids, whilst, on the other, a flattened v-shaped slot, with rounded vertex, is established, on whose vertex, the head or end corresponding to the gas cylinder, also rounded, is intended to rest, so that the assembly will be considerably simplified, since it is sufficient to insert the end corresponding to the gas cylinder inside said slot, in the absence of hinge pins.
  • the articulated joint of the other end of the gas cylinder to the second lid is not made directly thereon, as is conventional, but with the collaboration of an intermediate cam, which is whereon said hinge pin is established, with the special characteristic that said cam tilts between two extreme points, which generates a dead point in the tilting movement of either of the lids, proximate to the closed position, so that either of said lids tends, due to the effect of the gas cylinder, towards the open position above said dead point, meaning that the gas cylinder acts as a brake in the lid lowering manoeuvre, whilst below said dead point, and due to the cam tilting effect, said gas cylinder acts in the opposite direction, i.e. tending towards the closed position of the lid and, in consequence, maintaining this properly stabilized in the closed position.
  • Said cam has an orifice to be articulately fastened with the aid of the corresponding pin, to one of the container lids, and with an appropriate configuration to have its limit in two extreme points on the trunnion axis associated to said lid, as well as having a forked area whereby the end corresponding to the gas cylinder is articulately joined.
  • the cylinder or each gas cylinder (4) is finished at one of its ends in a rounded head (5) which is housed in a flattened v-shaped slot (6), operatively established on one of the lids (1) and of a depth so that it largely houses therein the body of the cylinder body (4), the rod thereof (4') emerging to the exterior therefrom.
  • the gas cylinder (4) is immobilized transversally and permanently tends to rest on the rounded vertex of said slot (6) due to the effect of its own tension, whatever position is adopted by the corresponding lid (1).
  • the gas spring (4) incorporates, on the free end of its rod (4'), a perforated head (7) wherein a pivot pin (8) is loosely established, which is articulated to the gas cylinder (4) with a cam (9), of a triangular-like contour, with rounded vertices, provided for said purpose, and beside one of said vertices, with a groove (10) which gives it a forked structure, with orifices (11) on its side portions to couple the pivot pin (8) and with its side (12) opposite said curved-concave fork (10), further incorporating a second orifice (13) whereby the cam (9) is hinged to the extension (3) of the other lid (1'), an orifice (13) wherein the corresponding through pin (14) articulately joined to said extension (3) is housed.
  • the special arrangement of the hole (13) determines, as is observed in figures 1 and 2 , that said curved-concave edge (12) of the cam, is considerably distanced from the axis (2), determining two stable extreme points for the cam (9), one of opening, wherein the vertex (15) rests on the axis (2), as shown in figure 1 , and another of closed position, wherein the other vertex (16) is that which rests on said axis (2), corresponding to the closed situation as, in turn, is shown in figure 2 .
  • an intermediate dead point is established, proximate to the closed position of the lid, so that, from the limit position shown in figure 1 , when the lid lowers, the gas cylinder (4) progressively contracts until reaching said intermediate dead point, the moment when the cam (9) tilts on its through axis (14) passing to the position shown in figure 2 , wherein an abrupt, upwards movement of the head (7) which finishes the rod (4') of the gas cylinder, the trunnion pivot pin (8) of this end of the cylinder being positioned above the imaginary joint line between its other end (5) and the through pin (14), meaning that said gas cylinder tends, from said dead point, to displace the lid (1) towards the closed position and, in consequence, to maintain said closed position stable both for said lid (1) and for the complementary lid (1').
