Definitions

  • the invention relates to small containers, in particular cases, with a pivotally mounted lid on a lower part, pivotable between a closed position and an opening position locked in the closing direction, and on the side of the bearing on the lower part as well as on the lid, elastic projections attached to one another during the opening and closing movements glide along and create a snap effect.
  • a reusable bottle stopper according to US Pat. No. 4,158,902 can consist of a more elastic material.
  • This known closure provides hinges formed between a hinged lid and a lower part which can be fastened to the bottle neck, and between them a projection with an outer thickening formed on the lower edge of the lid, which protrudes radially inward from it Arranged, integrally formed with the lower part spring tongue cooperates to produce a snap effect during the opening and closing movement and to keep the lid open. Since the spring tongue is formed on the outer wall of the lower part and the thickening on the outer wall of the cover, they disturb the external appearance. The known snap mechanism is therefore unsuitable for use in cases for valuable objects.
  • the snap effect is weak and affected by relatively strong friction, because the spring tongue has only an outer, essentially flat pressure surface and therefore the direction of the pressure force changes only slightly during the opening movement.
  • the cover keeps the spring tongue formed on the outer wall of the lower part permanently in an inwardly deformed state, so that its spring force decreases considerably over the course of the storage period.
  • the invention has for its object to develop a small container with a snap effect and locking mechanism that produces a pronounced snap effect with simple, externally invisible means with a relatively steeply increasing resistance and after overcoming a climax, a powerful, automatic folding movement of the lid.
  • the elastic projections projecting from the inner walls of the lower part and of the cover are pins with thickened heads arranged in such a way that the heads of cooperating pins butt against one another during the opening movement of the cover, but with elastic deformation of at least one of the pins are movable past each other.
  • the effect of the proposed mechanism is based on the one hand on a deformation process essentially in the area of the pin or pins, on the other hand on the reversal of the direction of the pressure force component acting in the direction of movement of the cover. This is initially opposed to the movement when opening and closing the cover and then acts in the direction of movement, because the cooperating, rounded heads first hit each other with their front surfaces in the direction of movement and after lateral elastic deflection in the direction of the hinge axis in the second Repel phase with their rear surfaces. Due to point contact, the friction is low.
  • the strength of the snap effect and the desired holding force can be adjusted by dimensioning the diameter of the heads, the degree of lateral deflection and the cross section of the pins. It is enough very small lateral deflections when the heads slide past each other in the order of magnitude of about 0.3-1.0 mm in order to use pins, which themselves are only about 2 mm in diameter, and made of a solid plastic, such as. B. Acrylbutadienstyrol (ABS) exist to generate the desired holding force.
  • ABS Acrylbutadienstyrol
  • pegs are formed on the inside on the rear walls of the lower part and the cover between or next to the hinge parts attached there so that the lower part and the cover can be identical injection molded parts.
  • this is e.g. B. achieved in that both by the same amount of z. B. 1.75 mm from the center of the rear wall. If, in the example, heads with a diameter of 3 mm protrude about 1 mm above the pins on the opposite side, there is an elastic lateral deflection of the pins when the heads are pushed past each other by about 0.5 mm.
  • Film hinges are preferably used as the hinge or joint connection. These are provided with an embossed groove as a predetermined bending plastic strips, for. B. made of polyethylene or polypropylene. They can be glued to the rear walls of the lid and the lower part or inserted into matching, molded pockets. A particularly inexpensive version is obtained if the film hinge is formed in one piece with the lower part and / or the cover, the entire case including the snap and locking mechanism and possibly also the locking members securing the closed position can be produced in a single injection process.
  • film hinges have the further advantage that they firmly connect the two suite parts in the longitudinal direction of the rear wall and are rigid in this direction, so that the lateral forces occurring on the pins do not result in a relative displacement of the suite parts.
  • the joint function and the internal friction in the joint are not influenced by the lateral forces exerted by the pins.
  • two pins with heads on one etuiteil can interact with a pin arranged between them and head on the other part.
  • the central pin is only slightly deflected. The elastic deformation takes place primarily in the two lateral pins.
  • a spring force effective in the closed position which tends to cause the case to open automatically after the lid lock is released, can be produced in a practical embodiment with the same elastically deflectable pins with heads, by pressing them against the spring force before the closing movement ends the deformation can slide onto a second rounded or sloping surface, in which it can, for. B. can be a surface on a pin on the other etuiteil.
  • additional pins possibly without a head, could also be provided for this function.
  • the arched ones or inclined surfaces and / or the intrinsic elasticity of the hinge up to approximately the abutment of the second head interacting with it, so that the lid does not resist a certain resistance when using a hinge or other means which oppose an opening movement beyond the locked opening position can only have two, but three defined positions: the closed position secured by locking the cover, the locked open position of e.g. B. 90 °, in which the pin heads abut one another on the upper side, and a less open intermediate position in which the forces acting in the opening direction have led the pin heads to the mutual inner or lower contact.
  • the proposed mechanism can also be easily molded onto particularly thin-walled suite parts, even if they have a wall thickness of less than 1.2 mm.
  • material come e.g. B. ABS or styrene acrylonitrile (SAN) in question, but also other plastics of sufficient strength, such as. B. polystyrene or polyethylene, where appropriate depending on the material with a slightly larger wall thickness of z. B. 1.8 mm or more will work.
  • the case shown in Fig. 1 consists of a lower part 10 and a hinged lid 12 on its rear wall.
  • these two parts are identical injection molded parts.
  • the hinge between the two suite parts 10, 12 can also be of a conventional type.
  • a film hinge consisting of one or more plastic strips with an embossed predetermined bending point is preferred, which is attached to the rear walls of the etuiteile 10, 12 or molded in one piece.
  • the axis of rotation of the hinge is located between the rear walls of the etuiteile 10, 12 or somewhat outside of it, as can be seen from FIG. 2, where the joint is formed by a weak point 14 between the etuiteile 10, 12 which are integrally connected to one another.
  • the snap effect and locking mechanism described below is provided.
  • it consists of a pin 16 formed on the rear wall of the lower part 10 and the cover 12, with the semicircular shape shown in FIGS. 4 and 6 or an elongated, rounded cross-section and with a substantially round head 18 on the free end of the pin protruding beyond the edge of the rear wall.
  • the pin 16 formed on the rear wall of the lower part 10 with vertical extension protrudes very little, approximately 1 mm or less, depending on the design of the hinge 14, beyond the upper edge of the rear wall, in order to reach the head there 18 to pass. Because of the identity of the parts 10 and 12, the same applies accordingly to the peg 16 with head 18 formed on the cover 12.
  • the heads 18 do not protrude rearward over the inner upper edge of the rear wall, since they would otherwise prevent the case from closing completely. But even in the longitudinal direction of the rear wall, the heads 18 do not sit symmetrically on the pin 16. From FIGS. 3 and 5 it can be seen that they are each offset to the side on which the other pin is located.
  • the molded on the rear wall pin 16 is so far from the center of the rear wall that, according to FIGS. 3 and 5, the extensions of the two pins 16 lie essentially next to the other pin, but the heads 18 projecting laterally beyond the pin 16 against butt the other head 18 and, if desired, slide along the substantially semi-cylindrical circumferential surface of the pin 16 in the longitudinal and circumferential directions when the case is completely closed.
  • the interacting pins 16 with heads 18 initially ensure that the cover 12 remains under the action of the restoring force of the film hinge or other forces acting in the closing direction in the 90 ° open position shown in FIGS. 1 and 2, that is to say it is locked on one side.
  • a considerable amount of force must be exerted in order for the cover 12 to be locked out by the heads 18 that abut against one another
  • the heads 18 must be moved past each other in a mutually abutting manner while elastically deforming the adjacent regions of the pins 16. This is only possible by deflecting the heads 18 in the longitudinal direction of the rear wall against the spring force of the elastic deformation of the pins 16.
  • each head 18 now abuts against the rounded circumferential surface of the peg 16 formed on the other etuiteil and is thereby increasingly deflected further in the longitudinal direction of the rear wall while sliding along the circumferential surface of the peg towards the closed position shown in FIGS. 5 and 6 , in which the head 18 comes to rest against the rear wall.
  • the deformation of the region of the pegs adjacent to the head by the other peg is substantially less with this deflection than with the mutual deflection of the heads 18 sliding past one another.
  • the heads and pins can also be dimensioned such that the heads do not slide onto the pins.
  • a pin 16 with head 18 formed on the cover 12 acts together with two with a small spacing apart molded on the rear wall of the lower part 10 pin 20 with heads 22.
  • the pin 16 with head 18 is neither when the heads 18 and 22 slide past each other when overcoming the locking or when pivoting the cover 12 in the closed position in the longitudinal direction of the rear wall deflected, because the forces exerted by the two heads 22 and by the two pins 20 on the head 18 in this direction cancel each other out.
  • the region of the pin 16 adjacent to the head 18 can, however, be elastically deflected in the direction described away from the rear wall. Such a deflection away from the rear wall also takes place in the embodiment according to FIGS. 1-6 in addition to the deflection in the direction of the rear wall. Since the forces acting in the longitudinal direction of the rear wall are compensated for in a case according to FIGS. 1 and 7-10, any hinges can be used
  • the heads 18 and 22 do not necessarily have a spherical shape and the pins do not necessarily have an approximately semicircular cross section.
  • the heads could e.g. B. can also be designed in a drop or egg shape.
  • Flattened heads on the side opposite the respective pin result in a particularly reliable fixing of the cover in the open position and a particularly impressive snap effect when closing.
  • the pins 16, 20 could, for. B. be shaped with a rectangular, triangular or trapezoidal cross-section, possibly in such a way that the heads 18, 22 run up before closing the cover 12 on an inclined surface through which they are increasingly deflected in the longitudinal direction of the rear wall until reaching the closed position .
  • An additional possibility to influence the spring and locking properties of the mechanism described consists in exposing the pins 16, 20 on a more or less large part of their length, starting from the head 18 or 22, from the rear wall of the lower part 10 or the cover 12 or only via a relatively narrow web with the rear wall connect.
  • the pins can then be bent elastically more easily in the longitudinal direction of the rear wall.
  • a gap or a groove between part of the pin 16, 20 and the rear wall does not interfere with the function described above in connection with FIGS. 4 and 6 or 8 and 10, as long as the point of contact of the head 18, 22 on which it increases as it closes laterally deflecting rounded or inclined peripheral surface of the pin 16 or 20 remains and does not get beyond the lateral edge of the gap or the groove. Only in the latter case could the head get caught behind the peg, as a result of which the lid would be kept closed instead of snapped open when the lock was released.
  • two or three further cooperating pins 24 with heads 26 can be attached to the rear wall of the lower part 10 and the cover 12, preferably, but not necessarily with the difference, that the heads 26 are hook-shaped or with stop surfaces and are arranged by the position and length of the pin 24 so that they open at a certain opening angle of z. B. 90 ° or a slightly larger angle against each other or hooking engagement. They therefore represent a stop that limits the opening area of the cover. This is particularly advantageous if a film hinge formed in one piece with the lower part 10 and the cover 12, due to its inherent elasticity, tends to extend the cover 12 far beyond the 90 ° position open out.
  • pins 16 with heads 18 for producing the snap effect combined with pins 24 and heads 26 forming stops are obtained one locks the cover in its 90 ° position in both swivel directions.
