The microstructure of the steel core is drawn lamellar pearlite. The metallic coating layer contains at least 84% by mass of zinc.

The present invention relates to a furniture hinge that is suited for changing damping course of the furniture door in the closing direction. The inventive furniture hinge comprises; a housing; a hinge arm that is connected to the furniture door from the one end and connected to said housing in an axially rotatable manner from the other end by means of a first rotating pin; a power unit having at least one spring that creates force on said hinge arm, and that is connected between a lever arm that is capable of accommodating a power adjustment thereon and a third rotating pin in an axially rotatable manner; a movement arm that is connected to said hinge arm from one end in an axially rotatable manner, that is connected to said lever arm from the other end in an axially rotatable manner, and that enables the power transmission between said power unit and hinge arm; a damping element located on said lever arm for damping the furniture door that is being closed over the furniture body; and a damping adjustment on said lever arm for the purpose of changing the position of a cylinder belonging to the damping element with respect to the lever arm.

The present invention determines the final opening position of the furniture door in the upward direction by means of the furniture hinge comprising an opening angle adjustment thereon. Said furniture hinge comprises a housing; a hinge arm connected axially to the furniture door from its one end and to said housing from the other end by means of a first rotating pin; a power unit that is connected axially between a lever arm and a third rotating pin and that comprises at least one spring forming a force on the hinge arm; a movement arm that is connected axially to said hinge arm from its one end and connected axially to said lever arm from the other end and that ensures the force transmission between said force unit and hinge arm; and an opening angle adjustment that allows for determining the final opening position of the furniture door in the upward direction, has an adjustment element in an axially rotatable and a damper thereon and comprises a body that may move linearly by means of the axial rotation of said adjustment element.

An actuating drive includes an actuating arm pivotally supported about a pivoting axis, and movably supported between a closed position and an open position. A force storage member applies a force to the actuating arm, and a coupling device can brake or prevent a pivotal movement of the actuating arm. The coupling device includes a movably-supported first coupling element having a tooth arrangement, and the first coupling element can engage a second coupling element when a predetermined pivotal speed of the actuating arm is exceeded to brake or prevent the pivotal movement of the actuating arm. The second coupling element includes an engagement section for engaging the two coupling elements together, and includes a freewheel section separate from the engagement section. In the closed position, the first coupling element is within the freewheel section of the second coupling element, whereby the two coupling elements are decoupled from one another.

A supporting element, in particular a spring strut, for adjusting a flap or door of a motor vehicle, including a base part, an extendable part that is adjustable relative to the base part, and a spring that is arranged between the two parts, is provided with a noise-reducing coating on the base part and/or extendable part on a surface facing the spring.

A drive device for a movable furniture part including a support to be fastened to a furniture carcass, an actuation arm device mounted movably on the support and to be connected to the movable furniture part, an energy store for applying force to the actuation arm device, a damping device for damping a closing and opening movement of the actuation arm device, and an adjusting device for adjusting a force of the damping device, a damping start position in relation to an angle position of the actuation arm device, and/or in terms of a damping travel. The adjusting device includes an adjusting element coupled to the damping device such that an adjustment of the damping force, damping start position, and/or damping travel takes effect when the actuation arm device is damped during the closing movement, and when the actuation arm device is damped during the opening movement.

A drive device comprises a housing, a drive portion, a spindle member to rotate by driving of the drive portion, a nut member screwed with the spindle member); a moving member coupled to the nut member, and a rotation regulating portion which suppresses rotation of the nut member to move the nut member) in an axis X direction of the spindle member, wherein the moving member has a fragile portion to be broken by a predetermined force being weaker than a force required to break the nut member, and the fragile portion is configured that a fracture portion with which the nut member is pressable by the moving member toward the drive portion is formable when the fragile portion is broken.

A multi-link hinge is proposed. The multi-link hinge is configured to facilitate closing and opening of a door, is capable of sufficiently securing a maximum opening angle of the door while decreasing a gap between the door and a main body, and is also capable of providing convenience to a user when the user opens and closes the door.

A door opening and closing device includes a slider and a main link mechanism. The slider moves along a roof of the vehicle body in a front-rear direction, while supporting a proximal end portion of a back door in such a way as to be rotatable around an axis extending in a width direction. The main link mechanism includes one end and an opposite end rotatably coupled to the vehicle body and the back door, respectively. The main link mechanism adjusts a posture of the back door, depending on a door opening degree by changing a distance between a coupling point to the vehicle body and a coupling point to the back door. The main link mechanism decreases the distance as the door opening degree becomes larger.
