Definitions

  • the present invention relates to a hinge for pivotally attaching a flap to a body of a piece of furniture or other body for closing and opening an opening of the body.
  • the invention further relates to a piece of furniture equipped with a multi-joint hinge.
  • Multi-hinge jingles are well known. They are used in particular for doors or flaps of a piece of furniture in order to pivotably guide this door or flap so that a user can move the door or flap from an open to a closed position or vice versa.
  • a simple hinge which is commonly used in room or front doors, for example, a multi-link hinge can create a more complex movement.
  • the door or flap is thus not only hinged to a pivoting edge on the piece of furniture, but rather can move freely in all edges of the opening.
  • the Mehrgefenksscharnier can optionally with the help of a corresponding Additional mechanics have the task to close the relevant flap and / or door in a closed state and in an open state - taking into account the gravity - keep open.
  • Multi-joint hinges are thus often used for flaps that open and / or close at the top and / or at the top, that is to say essentially have a horizontal pivot axis.
  • the term "flap" also includes elements such as doors.
  • a disadvantage of known Mehrgelenksscharnieren is basically their complex structure.
  • attaching a mechanism to open and / or close the respective flap is complicated and often depends on the very specific conditions of the flap, in particular Size and weight of the same.
  • the hinge must be selected depending on whether a flap opens downwards or upwards. In a downwardly opening flap, gravity aids in stopping, whereas gravity on an upwardly opening flap counteracts stopping.
  • a hinge according to claim 1 is proposed. Such has a base member for fixing to the furniture or the like, and a fixing member for fixing to the flap or the like.
  • the hinge has a movement mechanism for guiding the fastener and thus when used properly for guiding the flap on a movement path.
  • the trajectory is fixed with respect to the base element and thus when installed as intended with respect to the piece of furniture.
  • the movement mechanism can basically be designed in different ways, but at least one holding arm is provided.
  • This support arm is thus part of the movement mechanism and rotatably connected to the fastener and thus intended with the flap at a flap pivot.
  • the first support arm is connected to the fastening element and as part of the movement mechanism with the base element, that this first support arm relative to the base member only on a fixed predetermined Bewebungsbahn can move.
  • the first support arm is guided so that it maintains its orientation when moving on its predetermined path of movement.
  • the first support arm thus has only one degree of freedom and the only possibility of movement of this support arm depends on the movement of the fastener and thus intended from the movement of the flap.
  • a spring element for providing a bias for holding the flap in a closed and / or open state.
  • the spring element in particular a spring
  • the spring should be arranged on the hinge so that when used as intended a flap can be kept in an open state, in particular in a horizontal position, when the closed position is a vertical position.
  • This can also mean, in the case of downwardly opening flaps, that the spring can not close a flap open against the force of gravity due to its force and arrangement. In this case, the weight retained the flap without the spring prevents this.
  • it should also be taken into account in general how many hinges are used per flap. In many cases, two hinges are likely.
  • an auxiliary guide arm rotatably mounted on the base member is provided, which is rotatably mounted about an auxiliary pivot point.
  • a connecting arm is provided, which connects the auxiliary guide arm with the first support arm.
  • the connecting arm is rotatably mounted both on an auxiliary guide arm, namely in the region of a first connecting pivot point, and on the first holding arm, there at a second connecting pivot point.
  • the auxiliary guide arm can thus exert a force on the first holding arm by means of the connecting arm, if a force is introduced into the auxiliary guide arm.
  • a movement of the first holding arm on a predetermined path of movement via the connecting arm also leads to a substantially predetermined movement of the auxiliary guide arm and also of the connecting arm.
  • the described rotational movements or rotatable attachments are related to a rotation axis.
  • Ball joints that allow greater freedom of movement than one Allow rotation axis are not provided in principle.
  • described arms such as the support arm or the connecting arm, in principle also assume a physical configuration that differs from that of an arm.
  • the connecting arm could be designed as a straight strut or as a surface element, angle or even voluminous body for connecting the first and second connection pivot, if this is reasonable and feasible due to the given space.
  • the spring element exerts its power - directly or indirectly - on the auxiliary arm. This can be achieved according to the invention that the force acting ultimately on the fastener and intended on the flap, exerting its force depending on the position of the connecting arm and / or the position of the auxiliary guide arm.
  • the spring element is fastened with a first side to the base element and with its second side either on the auxiliary guide arm or on the connecting arm.
  • the spring element in particular the spring is designed as a tension spring.
  • the spring element thus produces a tensile stress between the base element and the auxiliary guide arm or the base element and the connecting arm.
  • the auxiliary guide arm extends from the auxiliary fulcrum in two substantially opposite directions, namely, to a first side, wherein the auxiliary guide arm is rotatably connected to the connecting arm in the region of this first side at the connecting pivot point, and to a second side, wherein the auxiliary guide arm in FIG Area of the second side, which is the first side substantially facing away, is prepared to be connected to the second side of the spring element. It may be advantageous to provide such a second side of the auxiliary guide arm without this side actually being connected to the second side of the spring element.
  • the spring element is connected to this second side of the auxiliary guide arm and applies a force between the base element and this second side of the auxiliary guide arm.
  • the invention proposes that the hinge be prepared to be used, depending on the position of the spring element, for use with an intended upwardly or downwardly opening flap. It is advantageous if the hinge is prepared to keep the flap in an open, in particular horizontal, and in a closed, in particular vertical position when used as intended. Due to the weight force acting strongly on the flap, especially in the open, horizontal state, the requirements for the hinge for holding the flap are very different, depending on whether the flap opens upwards or downwards.
  • a hinge of one embodiment is characterized in that its use as a hinge for an upwardly or downwardly opening flap is determined by the position of the spring element.
  • One and the same hinge can thus be changed by converting the spring element from a hinge for a downwardly opening flap to a hinge for an upwardly opening flap.
  • the hinge is dimensioned so that in both cases the same spring element can be used.
  • the hinge is characterized in that the spring element is attached to the auxiliary guide arm and exerts a force on the first holding arm via the auxiliary guide arm and the connecting arm, wherein the force in the open Condition of the flap is directed in a direction to keep open the flap and is directed in the closed state in a direction to keep the flap closed, wherein the direction of force preferably depends on the position of the connecting arm.
  • the spring member is attached to the auxiliary guide arm so as to exert a force thereon.
  • This force is further transmitted via the connecting arm on the first arm.
  • the said force thus either supports the opening or the closing of the flap or the holding open or keeping closed the flap.
  • This can be achieved in particular by the position of the connecting arm relative to the holding arm.
  • the position of the connecting arm relative to the holding arm By the movement of the flap and thus the movement mechanism including the first support arm, the position of the connecting arm relative to the support arm and thus the direction of force exerted by the auxiliary guide arm on the connecting arm on the support arm.
  • a force is possibly transmitted indirectly. This can also be done by the type of movement mechanics, in particular depend on how the first arm is guided.
  • the hinge is thus adapted to assume a state of reversal of the force acting on the fastener and thus the flap between fully open position and fully closed position.
  • a hinge of another embodiment is characterized in that the movement mechanism comprises: the first support arm, a second pivotally connected to a second flap pivot pivotally connected to the mounting arm support arm, a first guide arm which is rotatably connected to the base member at a first base pivot point with the first support arm at a first support pivot and the second support arm at a second support pivot, a second guide arm rotatably connected to the base member at a second base pivot and the first support arm at a third support pivot.
  • the movement mechanism thus essentially has a first and a second retaining arm and a first and a second guide arm.
  • both retaining arms are arranged parallel to one another, at least in the region from the first guide arm to the fastening element.
  • the two guide arms are also preferably formed parallel to each other. This ensures that the two retaining arms remain partially formed while moving parallel to each other. This is achieved in particular by the fact that the distance between the two flap pivot points and the two holding fulcrums is the same.
  • the first and second holding fulcrum and the first and second flap fulcrum mark a parallelogram.
  • the first and second base fulcrum and the first and third fulcrums also signify a parallelogram. When this parallelogram attached to the base member assumes the shape of a rectangle due to its movement, it is at a turning point.
  • the hinge is formed so that the described parallelogram of the first and second base fulcrum and the first and third holding fulcrum assumes the special shape of a rectangle in a position of the hinge between its intended fully opened and fully closed condition. It is favorable when the connecting arm engages between - in particular centrally between - the first and third holding fulcrum.
  • a hinge is proposed, characterized in that the first and second connection fulcrum define a connection path, the first connection fulcrum and the auxiliary fulcrum define an auxiliary path and, when used as intended, the connection path with the auxiliary section in the closed state of the flap an acute Form angles, preferably in the range of 30 ° to 85 °, in particular in the range of 45 ° to 80 ° and in the open state of the flap form an obtuse angle, preferably in the range of 120 ° to 175 °, in particular in the range of 135 ° 170 °.
  • an acute angle is proposed as an angle ⁇ 90 ° in the intended closed state of the door, whereby a force effect of the connecting arm on the first holding arm is achieved in a closing direction of the flap or favors, thereby holding the flap in a closed state.
  • an obtuse angle ie an angle> 90 ° and ⁇ 180 ° is proposed.
  • a so-called toggle effect occurs, according to which the first connection pivot point is for the knee joint and an angle of 180 ° would correspond to a complete extension.
  • Such a full extension can thus hold the flap without significant force by the spring, if the direction of force of the connector points in the opening direction. Since in the case of a 180 ° angle, the flap would not be closed by a user, a slightly smaller angle than 180 ° is proposed.
  • the movements referred to in this application basically refer to movement in a plane.
  • a Mehrgelenksscharnier z. B. be arranged on the edge of a cabinet wall or cabinet partition wall - with or without fairing - and the movements, in particular the movements of the movement mechanism in this case extend in said wall or partition or in a plane parallel thereto.
