Wing arrangement useful as an insect repellent door, comprises a wing mounted on a shaft by two coaxial mutually offset hinges located on a floor, where the wing is pivoted from one position into an initial position by a resetting device

摘要

The wing arrangement comprises a wing (2) rotatably mounted on an associated shaft by two coaxial mutually offset hinges (4, 5) that are located on a floor (1), where the wing is pivoted from one position into an initial position by a resetting device, which comprises a torsion spring (6). The hinges are bridged and comprise coaxial end portions (7, 8), each of which forms a hinge pin of the associated hinges. One end portion rotatably cooperates with a stationary hinge part and an other end portion rotatably cooperates with a movable hinge part of the respectively assigned hinge. The wing arrangement comprises a wing (2) rotatably mounted on an associated shaft by two coaxial mutually offset hinges (4, 5) that are located on a floor (1), where the wing is pivoted from one position into an initial position by a resetting device, which comprises a torsion spring (6). The hinges are bridged and comprise coaxial end portions (7, 8), each of which forms a hinge pin of the associated hinges. One end portion rotatably cooperates with a stationary hinge part and an other end portion rotatably cooperates with a movable hinge part of the respectively assigned hinge. All hinge parts comprise a through recess with a cross-section deviating from a circular shape. Each end region of the torsion spring in the region of its rotation of a portion cooperating with the hinge part exhibits a cross-section corresponding to the cross-section of the passage recess and in the region of its rotation of a portion cooperating with the hinge part exhibits a circular cross-section with a diameter of the inscribed circle of the cross-section of the through recess. The hinges are constructed from four identical hinge parts. The torsion spring is: formed as a straight torsion rod, which shows outer portions with circular cross-section going through a cross-section corresponding to the cross-section of the through recess; and provided with a circular-sectioned spigot at their opposite ends. The cross-section of the through recess deviating from the circular shape has a shape of a regular hexagon. The torsion spring surpasses with an end portion of the respectively adjoining hinge part and is equipped with a security ring adjoining at the end portion. The wing is formed as an insect repellent door, which comprises: a framework having an insect repellent fabric, where the floor and the wing are made of profiled sections with corresponding cross sections, each of which has a same distance from the rotational axis; and an undercut groove for fixing the associated hinge portions. The wing is formed with a magnetic locking unit with a closed chamber.
