Definitions

  • the present invention relates to a hinge according to the preamble of claim 1.
  • a so-called snap effect should be brought about regularly with such hinges for plastic closures .
  • a snap effect is understood to mean opening the hinge automatically after a certain forced initial deflection (dead center) of the hinge system and an analogous effect when closing, in that the hinge automatically returns to a closed position after a dead center has been exceeded. This effect is basically taken over by special spring elements.
  • the snap force and the angle of action are characteristic quantities.
  • the snap force is the resistance that the hinge system has to opening and closing.
  • the angle of action is defined by the area which the hinge parts independently overcome due to the spring action and is thus determined by the area between the rest positions of the hinge parts.
  • European patent EP 0 056 469 describes a hinge for a plastic closure, whose axis of rotation by a defined, the lid and main film hinge connecting the closure body is formed and clearly defined.
  • the A snap effect is achieved by interacting with the side this main hinge arranged spring arms reached.
  • the snap effect is based on one embodiment on the bend of U-shaped intermediate elements in other embodiments on one Bending wall areas of the closure parts, wherein usually the cap has a bend in the middle experiences.
  • the snap effect also comes here caused by bending effects around the narrow side.
  • U.S. Patent No. 5,148,912 describes one Hinge arrangement for a closure with a closure body and lid, with which the closure has the same circular cross section as the closure body itself. Lid and closure body are via two flexible, belt-like connecting arms that are trapezoidal, connected. These connecting arms are flexible and over Thin spots on the closure and on the closure body attached.
  • the hinge-side film hinges the thin spots are arranged at an angle to one another. If you look at the closure from behind, so these film hinges are inevitably random arranged in the form of a V open at the bottom.
  • the arrangement of the two lid-side film hinges is mirror-symmetrical. This hinge points not a good snap effect because there are no suitable ones Spring forces can be built up.
  • the known hinge arrangements have various disadvantages. With all known hinges with a major axis against which Tension straps or similar elements are staggered (joint axis offset), there is a need to this main axis for convex injection molding closures outside the closure outer contours to arrange. The above elements are however out technical and aesthetic reasons undesirable. Another disadvantage is that the snap effect because of the difficult mechanical influences is unpredictable and regular to one insufficient snap effect or too impermissible Material stresses leads. Another disadvantage is the fact that conventional hinge arrangements only unpredictable and insufficient angles of action enable that often only at about 100 ° lie. It is because of the well known principles unpredictable mode of action particularly disadvantageous, that for a design-wished, new locking geometry each complex prototype series must be made to a technically to achieve satisfactory closure kinematics.
  • the one with conventional closures Main hinge means that the locking parts in the Spray condition must be very close to each other.
  • the corresponding injection mold therefore has the Disadvantage that the wall thicknesses in this area, due to the inevitable connection between the Closure bodies must be made very thin.
  • the subsequent cooling and wear problems have a negative effect on the cycle time and the service life of the injection mold.
  • Hinge arrangements which are made in one piece from plastic can be injected is that only systems can be achieved with a maximum of one snap effect can.
  • a maximum of one snap effect can be achieved for the opening process of the closure beyond a maximum of one Dead center reached a maximum of two rest positions. These rest positions are essentially the open and the closed Condition of the closure. Because of the regular occurring plastic deformations falls the open rest position is not with the position in the injection molding state together.
  • the mechanical effects that work such closures are based on essential spiral spring effects.
  • the energy that needs is used to deform a bending element by means of bending, determines the snap force of the hinge. Becomes an element of a bend relevant to this effect the corresponding bending deformations are exposed these elements are large compared to it characteristic sizes (e.g. thickness of a bending plate) or the spiral springs have in the unloaded Condition a considerable spatial expansion.
  • the necessary functional elements of conventional hinge arrangements like main hinge and straps, not Realize more or lead to insufficient Snap effects or impermissible material stress.
  • Another limitation is that the closures in the area of the hinge are necessarily have a convex outer contour have to.
  • the hinge parts are advantageous, for example, when an obstacle area has to be overcome. But the movement path also has a meaning when the two hinge parts functionally interact Contain elements.
  • the two hinge parts functionally interact Contain elements.
  • plastic closures it is essential that the pouring spout with its sealing counterpart meet at a favorable angle to achieve an optimal seal.
  • the invention enables a hinge system which has two or more essentially tension-free rest positions and intermediate dead points during the opening and closing process.
  • the states beyond the dead centers are predetermined and controlled.
  • the functional, mechanical effects are no longer bending effects around the narrow side, but coordinated pulling and pushing effects with their possible secondary appearances. If functionally important elements of the present invention are subjected to bending, this is only secondary. Such bending deformations are prevented as far as possible by appropriate technical measures (e.g. rigid design of the pressure element concerned).
  • the hinge type according to the invention draws further characterized by the fact that z. B. with sprayed one-piece plastic closures none protrude disruptive parts from the closure contour.
  • the idea of the invention aims at the necessary design and concentrate functional elements that an essentially predictable Kinematics of the closure is achieved while ensuring that the end positions and the intermediate resting positions of the closure largely are tension-free.
  • the snap force is exclusive through the concentrated, between the hinge parts lying, functional elements.
  • cover and closure body of a plastic closure can with freely definable stiffness and largely any geometry.
  • the invention has no fixed main motion axis. At any point in the movement process, only a momentary, non-fixed pivot axis can be determined, which can also be skewed at times.
  • This virtual axis which moves during the movement process, is not physically present and does not coincide with a structural part of the hinge. Nevertheless, the cover parts move on the intended path and reliably reach the end position intended for them. The position and movement of this virtual axis and thus the relative movement of the hinge parts are significantly influenced and controlled via the geometric structure of the hinge mechanism.
  • the hinge according to the invention which articulates at least two hinge parts, consists of one or more tilting steps, each of which is bordered by rigid intermediate members or the hinge parts themselves.
  • a single tilting step has the purpose of giving the hinge a certain partial snap force and partial angle (in relation to the total opening / closing movement) and is responsible for a snap effect. If several tilt levels are connected in series, the hinge receives the same number of snap effects as tilt levels. When opening or closing, the hinge passes as many dead centers as there are tilting stages connected in series. Each flip-flop thus carries a certain proportion of the total angle of effect.
  • the corresponding partial angle can assume a certain desired size through a corresponding geometric arrangement of the functionally important elements of a tilting step. A relationship between the partial angle of a tilting step and the geometric arrangement exists and is used in a targeted manner.
  • FIG. 1 shows a schematic representation the functional elements of a flip-flop 1 in the closed Status.
  • the flip-flop contains two pressure elements 2.1, 2.2, which are articulated, e.g. via film hinges, connected with two intermediate links 20, 21 are.
  • Two tension elements 3.1 and 3.2 are parallel to arranged these pressure elements.
  • Between Pressure elements 2.1, 2.2 and the two tension elements 3.1, 3.2 two thrust elements 4.1 and 4.2 are arranged.
  • the flip-flop thus has two functional groups, namely two connecting elements 5.1, 5.2, which in turn one push element 2, one pull element 3 and contain a thrust element 4.
  • the functionally important ones Elements are articulated with the stiff pontics 20 and 21 connected. This flexibility can with plastic injection molded lids with the help of thin points or analogous arrangements can be achieved.
  • the intermediate links 20 and 21 limit the here Tilt level 1 or the tilt level is directly with here Hinge parts not shown directly connected.
  • the pressure and tension elements act as compression springs or as elastic Spring elements and cause the spring effect per connecting element. If the critical dead center is reached, the flip-flop jumps into the open one without further action Position.
  • the proportion and arrangement of the pressure 2.1, 2.2 and tension elements 3.1, 3.2 are determined in such a way that optimized angles of action and snap forces occur. It is essential that the required in the pressure element Pressure forces initiated and without buckling can be included. This is the thickness of the Pressure elements in relation to the thickness of the tension elements to consider. Insufficient thickness of the printing elements leads to unfavorable snap behavior.
  • the end points of the pressure and tension element of a connecting element 5.1, 5.2 make an angle ⁇ one, which will be explained further below, according to the invention to achieve the desired partial angle Flip-flop is used.
  • closures of different shapes or designs even if they are based on the same principle, have very different snap effects and different snap forces.
  • Certain versions of these closures even completely miss a snap effect, although this is an explicit target of corresponding patent specifications.
  • the reason for this lies in the complex mechanical processes on which such hinges are based, or in the fact that the hinge parts themselves make a significant contribution to the functioning of the closure and thus, even with slight changes in geometry, effects which are not easy or unforeseeable occur.
  • These disadvantages are remedied by the present invention in that the functionally essential elements are reduced to a minimum and are concentrated locally and in their spatial extent, but at the same time allowing more flexible movement sequences compared to conventional hinge principles. This is especially true in contrast to snap locks with fixed main axes of movement, which always describe a rotational movement with a spatially fixed axis of rotation relative to one another.
  • the operating principle of flip-flop 1 is based on the presence of one or more pressurized Pressure elements 2.1, 2.2 which in active combination to suitably arranged tensile loads Tension elements 3.1, 3.2 stand.
  • Pressure elements 2.1, 2.2 which in active combination to suitably arranged tensile loads
  • Tension elements 3.1, 3.2 stand.
  • pressure and tensile forces are specifically introduced. With unwanted movements, it is unavoidable that secondary pressure loads on the Tensile element act. These are undesirable forces but much smaller than those that occur in normal operation Tensile loads and are in terms of intended function of the hinge negligible.
  • pro Tilt level 1 at least one thrust element 4.1, 4.2 is provided.
  • This thrust element 4.1, 4.2 is essential for the invention, by preventing unwanted movements and the locking parts around their virtual movement axis coordinated.
  • the thrust element can be as in Figure 1 each a pull with a pressure element directly connect, or provided elsewhere become.
  • the resilience and the total angle of action, hence the snap effect of a flip-flop according to the invention essentially only with the help of compression and tension elements and not by bending springs reached.
