Definitions

  • the invention relates to an opening mechanism for actuating a spring, which is supported by a compression spring, and is pivotably hinged to a wall or a housing between an open position and a closed position, according to the preamble of claim 1.
  • an opening mechanism of this type is common for car trailers with a box body.
  • a gas pressure spring is arranged there to support the open position of the cover between the housing of the structure and the cover.
  • Systems of this type are also known for trunk lids or hatchbacks of station wagons or hatchbacks.
  • an opening mechanism for front flaps of extractor hoods in which a right-angled rigid lever is arranged as the first lever on a folding door, which lever is connected via a second, movable lever to a third lever rotatably mounted on the housing is.
  • the levers are U-shaped in cross section.
  • a tension spring which is mounted on the housing and suspended at the connection point between the third and the second lever, serves as a weight compensation element.
  • the design and arrangement of the three levers and a tension spring is intended to ensure that the flap door can be fixed in any open position without an additional braking device, by compensating for the restoring torque, which increases when the flap door is opened, by the levers.
  • the opening mechanism which extends over the entire depth of the housing, can only be used to a limited extent in the case of car trailers with a box body, in trunk lids or flaps of combi or hatchback cars due to the space requirement.
  • the invention has for its object to provide an opening mechanism that enables a good seal between a wing, in particular a lid, and a wall or a housing with a particularly low technical effort.
  • the object is achieved in an opening mechanism for actuating a spring with pressure-assisted actuation of a wing which is pivotably articulated on a wall or on a housing between an open position and a closed position, in particular a cover, with a pressure spring which is mounted between a first bearing point on the cover or housing and a connection point of a first and second lever arm, the free end of the first lever arm being articulated in a second bearing point on the cover or housing, in that in the closed position the connection point and thus also the compression spring is arranged substantially axially between the first and second bearing points with the force of the compression spring substantially between the two bearing points.
  • the free end of the second lever arm is mounted in a third bearing point which is arranged on the housing when the first and second bearing points are mounted on the cover. However, if the first and second bearing points are arranged on the housing, the second lever arm is mounted in a third bearing point arranged on the cover.
  • the compression spring is thus attached via the first lever arm to two bearing points on the cover or on the housing.
  • the first lever arm and the compression spring lie essentially uniaxially between these bearing points, as a result of which the spring force of the compression spring only acts on these two bearing points.
  • the compression spring is deflected by the second lever arm located between the connection point between the first lever arm and the compression spring and the housing or cover.
  • the first lever arm and the compression spring are no longer uniaxially between the two bearing points, but with increasing deflection of the compression spring, the spring acts increasingly in a direction perpendicular to the connecting line between the first two bearing points.
  • This vertically acting component can e.g. be used on the housing to support the opening movement and / or the opening position of the cover.
  • the hinges for attaching the cover or the effort for sealing the connection between the housing and the cover can be kept small, because in the closed position of the cover, no force is introduced between the cover and the housing by the compression spring.
  • opening mechanisms can be arranged on both sides of the cover, as is known in automobile construction for opening heavy, large hatchbacks.
  • a gas pressure spring of the common type can be used as the compression spring, the size and spring force of which must be adapted to the requirements.
  • the opening mechanism according to the invention can be used particularly advantageously for actuating the lid of car trailers, in automobile construction for opening lids, flaps and doors and also for actuating the lid of larger containers.
  • the bearing pin for the articulation of the lever mechanism on the housing can be held on a bearing arm which projects vertically from the housing wall.
  • the opening mechanism is also suitable for use with skylights, windows and doors in houses and halls.
  • FIG. 1 and 2 show a container 10 as an attachment for a car trailer.
  • the container 10 has a box-shaped housing 12, the upper end surface of which can be closed by a cover 14 which is hinged to the housing with hinges 15.
  • the edges of the cover 14 are bent towards the housing 12 and thus form lateral end walls 16 which rest in the closed position of the cover 14 on the side walls of the housing 12.
  • the end wall facing the viewer 16 of the cover 14 carries on its inside facing the housing interior a metal base plate 18, which has a bearing pin 20, 24 on each of its two longitudinal ends.
  • On the front bearing pin 20, one end of a gas pressure spring 22 and the pin axis is pivoted.
  • the rear bearing pin 24 serves to receive a first lever arm 26 which is pivotally connected to the other end of the gas pressure spring 22.
  • the distance between the two bearing pins 20, 24 corresponds to at least the length of the first lever arm 26 and the length of the gas pressure spring 22 in the compressed position (FIG. 2).
  • a second lever arm 30 engages, which is pivotably mounted on a lower bearing pin 32 arranged on the housing 12.
  • the lower bearing pin 32 is mounted on a mounting plate 34 which is connected to the housing 12, for example by screws or rivets.
  • the gas pressure spring 22 adjusted by the first and second lever arms 26 and 30 such that the longitudinal axis of the gas pressure spring 22 corresponds approximately to the direction of the second lever arm 30.
  • the force of the gas pressure spring 22 thus acts primarily between the front bearing pin 20 arranged on the cover 14 and the lower bearing pin 32 arranged on the housing, the cover 14 being held in its open position by the spring force.
  • Such opening mechanisms can be arranged on both sides of the cover if it is very large or very heavy, for example.
  • the mechanics can also be used for lifting roofs in cars or for skylights or lifting windows in roof structures of houses or halls.
  • the walls of the carriage or the hall would then lie in the area of the end walls of the cover parallel to its plane in the closed position.
  • the lower bearing pin would be arranged on a bearing arm projecting essentially vertically downwards from the wall.
  • the end walls of the lid In the closed position, the end walls of the lid would rest directly on the wall surface or on sealing edges or strips arranged on the wall surface.
