Abstract
Device for swivel holding of leaf flap which can swivel especially around a horizontal axis comprises a straight four-bar mechanism (8.1, 8.2, 10.1, 11.1) and elastic means (18) to damp the swivel motion. The elastic means have spring element (18) which is guided with its extensible part to move around anchoring element (7). Anchoring element (7) is for example a plastic ring which is inserted in hinged frame (1) of device. Its diameter corresponds to a multiple of a diameter of spring element (18). The entire device is preferably structured symmetrically with respect to the plane defined by the movement of four-bar mechanism (8.1, 9.1, 10.1, 11.1).
Claims20
A device for swivel-holding of a leaf flap, comprising
- a generally planar-shaped frame having a pair of opposite front and back ends,
- a straight four-bar mechanism including at least two turning arms, each of said at least two turning arms having a first end portion and a second, swiveling end portion, said first end portions being rotably connected to the frame at a first side thereof, and at least two angle arms, one of said at least two angle arms being articulated to each of said second, swiveling end portions, the other angle arm being articulated to each of said at least two turning arms, said at least two turning arms and said at least two angle arms forming a hinged parallelogram,
- a swivel arm for swivel-holding of the flap, said swivel arm being connected with a front end of each of the angle arms to perform a rotation about an axis substantially perpendicular to the planar-shaped frame between an open position and a closed position,
- an elastic means for damping or balancing the swivel motion of the leaf flap, the elastic means having two ends, and
- an anchoring element disposed at the back end of the frame, wherein
- the elastic means is connected by said two ends to the four-bar mechanism and guided around the anchoring element.
A cabinet with a swiveling door, wherein the door is guided and held by two devices, each of said two devices comprising:
- a generally planar-shaped frame having a pair of opposite front and back ends,
- a straight four-bar mechanism including at least two turning arms, each of said at least two turning arms having a first end portion and a second, swiveling end portion, said first end portions being rotably connected to the frame at a first side thereof, and at least two angle arms, one of said at least two angle arms being articulated to each of said second, swiveling end portions, the other angle arm being articulated to each of said at least two turning arms, said at least two turning arms and said at least two angle arms forming a hinged parallelogram,
- a swivel arm for swivel-holding of the flap, said swivel arm being connected with a front end of each of the angle arms to perform a rotation about an axis substantially perpendicular to the planar-shaped frame between an open position and a closed position,
- an elastic means for damping or balancing the swivel motion of the leaf flap, the elastic means having two ends, and
- an anchoring element disposed at the back end of the frame, wherein
- the elastic means is connected by said two ends to the four-bar mechanism and guided around the anchoring element.
