Description

The The present invention relates to a hinge for pivotal mounting a flap on a body of a piece of furniture or other body to close and open an opening of the Body or body. Furthermore, the invention relates to a multi-joint hinge equipped furniture.

Multi-joint hinges are well known. They are especially for doors or Flaps of a piece of furniture used around this door or Flap to guide swiveling allow a user the door or flap from an open one can move to a closed position or vice versa. Opposite one simple hinge, which is common in room or front doors, for example used, a multi-joint hinge can be a more complex movement create. The door or Flap is thus not only hinged to a pivot on the piece of furniture, but rather can be found in all Move edges free from the opening. In addition, the Mehrgelenksscharnier can optionally with the help a corresponding additional mechanics task, the relevant Flap and / or door closed in a closed state and in an open state Condition - under consideration gravity - keep it open. Multi-hinge hinges are thus often used for flaps, which after open at the bottom and / or at the top or close, so essentially have a horizontal pivot axis. following The term "flap" also includes elements like doors.

adversely in known Mehrgelenksscharnieren is basically their complex structure. Besides the need to provide a variety of pivot points, the one trajectory for the To pretend flap to attach, is also the attachment of a Mechanism for holding open and / or closed the concerned Flap complicated and hangs often from the very specific conditions of the flap, in particular height and weight from the same. It should be added that both the up and the closed hold a Flap the hinge depending to choose from is whether a flap opens down or up. In a downward opening Flap supported Gravity stopping, whereas gravity at one opening up Flap counteracts stopping.

task The present invention was thus, if possible, one or more to remedy or defuse the above-mentioned disadvantages, in particular It was a task, a cost and / or construction cost-effective Hinge as possible should be universally applicable. At least it was the task of the present Invention to provide an alternative hinge.

According to the invention is a Hinge according to claim 1 proposed. Such has a base element for fastening on the piece of furniture or the like, and a fastener for attachment to the flap or like that.

Farther The hinge has a movement mechanism for guiding the fastening element and thus when used as intended to lead the flap on a trajectory. The trajectory is in Reference to the base element and thus when properly installed in relation to the piece of furniture specified. The movement mechanics can basically be different Be fashioned, but at least one arm is provided. This holding arm is thus part of the movement mechanics and rotatably with the fastener and thus intended with the Flap connected to a flap pivot. Preferably, the first holding arm so with the fastener and as part of the movement mechanics connected to the base element, that also this first holding arm relative to the base member only on a fixed path of movement can move. Preferably, the first support arm is guided so that when moving on its predetermined trajectory its alignment maintains. In his movement, he is thus basically in relation to his previous Position moved only parallel. So he takes in the installed state a horizontal position z. B. based on an upper edge, so This horizontal alignment is maintained during the movement. The first support arm thus has only one degree of freedom and the only possibility of movement this holding arm hangs from the movement of the fastener and thus intended by the Movement of the flap off.

Furthermore, a spring element for providing a bias for holding the flap in a closed and / or open state is provided. The spring element, in particular a spring, can thus in particular with respect to a piece of furniture pull a flap inwards and hold when it is in the closed state or close to the closed state. In addition, the spring should be arranged on the hinge so that, when used as intended, a flap can be kept in an open condition, especially in a horizontal position when the closed position is a vertical position. This may also mean for downwardly opening flaps that due to their force and arrangement, the spring does not close a downwardly open flap against the weight force can. In this case, the weight retained the flap without the spring prevents this. Of course, when dimensioning, it should also be taken into account in general how many hinges are used per flap. In many cases, two hinges are likely.

Farther is an auxiliary guide arm rotatably mounted on the base member provided, which is rotatably mounted about an auxiliary pivot point. Farther a connecting arm is provided which holds the auxiliary guide arm connects to the first holding arm. The connecting arm is for this both on an auxiliary guide arm, namely in the region of a first connection pivot point, as well as on the first holding arm, there at a second connection pivot, rotatable stored. The auxiliary guide arm can thus by means of the connecting arm, a force on the first arm exercise, provided a force in the auxiliary guide arm is initiated. Thus leads a Movement of the first holding arm on a predetermined trajectory over the Connecting arm to also a substantially predetermined movement of the auxiliary guide arm and also the connecting arm.

It It should be noted that the rotational movements described or rotatable Fasteners are related to a rotation axis. Ball joints, the one greater freedom of movement as a rotation axis allow are basically not provided. Furthermore can arms described according to the invention, such as the arm or the connecting arm, in principle also a physical embodiment accept, which deviates from that of an arm. For example, the connection arm could as a straight strut or as a surface element, angle or even voluminous body to Connecting the first and second connection pivot configured be, if this makes sense due to the space available and is feasible.

The Spring element exercises his power - directly or indirectly - up the auxiliary arm. This can be achieved according to the invention, that the Force effect, which ultimately affects the fastener and as intended on the Flap works, its power dependent from the position of the connecting arm and / or the position of Exercise auxiliary guide arm.

Preferably is the spring element with a first side on the base element attached and with its second side either on the auxiliary guide arm or on the connecting arm. Thus, depending on the arrangement of the Spring element, which will be simplified referred to as spring below may, a certain, from the position of the guide auxiliary arm and / or the Low connection dependent Power exercised become.

According to one another embodiment the hinge is characterized in that the spring element with a first side on the base element and with a second one Side on the guide arm or with the second side attached to the connecting arm. Preferably, the spring element, in particular the spring as a tension spring educated. According to the mentioned embodiment, the spring element thus a tensile stress between the base member and the auxiliary guide arm or the base member and the connecting arm.

Further Preferably, the auxiliary guide extends from the auxiliary pivot point in two substantially opposite directions. Namely too a first side, wherein the auxiliary guide arm in the area of this first side at the connection pivot point rotatable with the connecting arm connected to a second side, wherein the auxiliary guide arm in the area of the second page, the first page in essence turned away, is prepared to, with the second side of the spring element to be connected. It may be beneficial to have such a second Side of the auxiliary guide arm Provide this page without actually having the second page the spring element is connected. Preferably, the spring element but connected to this second side of the auxiliary guide arm and exercises one Force between the base member and this second side of the auxiliary guide arm out.

A preferred embodiment proposes that the hinge be prepared to be used depending on the position of the spring element for use with a designated 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. However, in order to provide an almost same hinge for both types of flaps, 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. Preferably, the hinge is dimensioned so that in both cases the same spring element can be used.

According to one another embodiment, especially for an upward opening Flap is provided, the hinge is characterized that the spring element is attached to the auxiliary guide arm and over the Auxiliary guide arm and the connecting arm exerts a force on the first holding arm, wherein the power in the open Condition of the flap directed in one direction to keep the flap open is and in the closed state in a direction to keep closed the flap is directed, the direction of force is preferably from the position of the connecting arm depends.

Therefore the spring element is attached to the auxiliary guide arm so that it exerts a force on it. This power will continue over transfer the connecting arm to the first support arm. Depending on the position the purpose-fixed flap supports said force thus either opening or closing the Flap or keeping the flap open or closed. This can in particular by the position of the connecting arm relative be reached to the arm. By the movement of the flap and so that the movement mechanics including the first holding arm changes the position of the connecting arm relative to the holding arm and thus the direction of force, the auxiliary guide arm on the connecting arm on the holding arm exercises. At the moment when the connecting arm or its direction of force is perpendicular to the given direction of movement is in the said direction of movement at most indirectly transmits a force. This may also depend on the type of movement mechanics, in particular depends on, as led the first holding arm becomes.

The Hinge is thus designed to be between completely open Position and complete closed position a state of reversal of the fastener and for the flap to take on acting force.

One Hinge of another embodiment is characterized in that the movement mechanics is the following comprises: the first holding arm, a second at a second flap pivot rotatably connected to the fastener holding arm, a first guide arm, the rotatably connected to the base member at a first Base pivot, with the first arm at a first pivot point and with the second support arm at a second support pivot, a second guide arm, the rotatably connected to the base member at a second Base fulcrum and with the first arm at a third holding fulcrum.

The Movement mechanics thus essentially has a first and second Holding arm and a first and second guide arm. Preferably Both holding arms are arranged parallel to each other, at least in Area from the first guide arm to the fastener. The two guide arms are also preferred formed parallel to each other. This ensures that the both holding arms in sections, even during the movement in parallel stay educated with each other. This is achieved in particular by that the distance between the two flap pivots and the is equal to two holding fulcrums. In particular, the mark first and second pivot points and the first and second flap pivot a parallelogram. Likewise, preferably the first and second base pivot point and the first and third support fulcrum also a parallelogram. If this attached to the base element parallelogram due to its movement takes the form of a rectangle is located it turns into a reversal point.

Preferably the hinge is designed so that the described parallelogram from the first and second base pivots and the first and third Holding fulcrum the special shape of a rectangle in one position the hinge between intended fully open and fully closed as intended State assumes. Cheap it is when the connecting arm between - in particular centrally between - the first and third holding fulcrum attacks.

According to one yet another embodiment a hinge is suggested that is characterized that the first and second connection pivot point is a connecting path define, the first connection pivot point and the auxiliary pivot point define an auxiliary route and when used as intended the connection with the auxiliary section in the closed state of Flap make an acute angle, preferably in the range of 30 ° to 85 °, in particular in the range of 45 ° to 80 ° and in open Condition of the flap form an obtuse angle, preferably in Range from 120 ° to 175 °, in particular in the range of 135 ° to 170 °.

Thus, an acute angle is proposed as an angle <90 ° in the intended closed state of the flap, whereby force of the connecting arm on the first holding arm reaches or favors a closing direction of the flap to thereby hold the flap in a closed state. In the open state, an obtuse angle, ie an angle> 90 ° and> 180 ° is proposed. Especially with Win close to 180 ° occurs a so-called toggle effect, according to which the first connection pivot point 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.

As a general rule It should be noted that the movements referred to in this application in principle refer to movement in a plane. Usually, a Mehrgelenksscharnier z. B. arranged on the edge of a cabinet wall or cabinet partition wall be with or without fairing - and the movements, in particular the movements of the movement mechanics run in this case in said wall or partition or in a plane parallel to it. In other words, most are or all pivot axes of the hinge, each at a pivot point are provided, formed parallel to each other.

In addition, according to the invention proposed a piece of furniture, which has a body with at least one flap. The flap is with at least one, preferably two hinges according to the invention movably attached to the body. Preferably, such Flip up a movement path of about 90 °, namely of a normal vertical closed position to a normal horizontal opening position.

following The invention will be described by way of example with reference to embodiments with reference to the accompanying figures are described.

1 shows a hinge according to the prior art for a downwardly opening flap in a properly closed state.

2 shows a hinge according to a first embodiment of the invention schematically in an intended closed position.

3 shows a hinge according to 2 schematically in an intended open position.

4 shows a hinge of another embodiment for use with an upwardly opening flap schematically in a designated closed position.

5 shows the hinge according to 4 schematically in an intended open position.

1 shows a hinge 101 according to the prior art. The hinge 101 has a base element 102 to attach to the body of a cabinet, as well as a fastener 104 for securing a flap to move relative to the body. The hinge shown 101 is intended for a downwardly opening flap and the fastener 104 is to be fastened in a lower area of the flap.

The hinge 101 has a first and second support arm 106 and 108 on that on the fastener 104 rotatably in a first and second flap pivot 110 and 112 are attached, so over the fastener 104 to hold the flap on a predetermined path of movement.

The holding arms 106 and 108 are in turn by means of a first and second guide arm on the base member 102 rotatably mounted.

To open would have to a corresponding to the fastener 104 to be fastened flap according to 1 pulled to the left, causing the movement mechanism consisting of the fastener 104 , the first and second arm 106 and 108 and the first and second guide arms 114 and 116 would also move to the left, in addition to the fastener 104 along with the flap attached to it, tilts to the left. This corresponds to the opening movement of the flap down.

During this opening movement, the spring 118 between the first support arm 106 and the base element 102 is attached with a bias, stretched and counteract said opening movement.

By the spring 118 Thus, a flap can be held in a closed position and the spring 118 also facilitates the closing movement. When dimensioning the spring 118 make sure that it is not too strong to prevent accidental closing of the flap from the open state. This hinge is for use with an upwardly opening flap which is intended to be stopped by the hinge when open 101 not suitable. It would either have to choose a different hinge, or an additional mechanism to achieve the retention of an upwardly opening flap.

The 2 to 5 basically show schematically a hinge that is basically only between through the representations of these four figures the respective position closed according to 2 and 4 and opened according to 3 and 5 on the one hand and the position of a spring 18 for use with a flap opening in accordance with 2 and 3 and for use with an upwardly opening flap in accordance with 4 and 5 different. For this reason, to explain the 2 to 5 essentially the same reference numerals are used. In particular, the hinge of all 2 to 5 as a hinge 1 designated.

First, the hinge 1 with reference to the 2 explained in more detail. The hinge 1 has a base plate as a base element 20 and a base strut attached thereto 22 on. The base plate 20 is attached to the body of a piece of furniture, which is in the 2 - and also the 3 to 5 - but not detailed. Furthermore, the hinge has 1 a fastener 4 on, that at a flap 24 is attached in the 2 to 5 only hinted at.

The flap 24 is about the fastener 4 with the first and second support arm 6 . 8th connected. The connection is in each case rotatably movable at the first and second flap pivot point 10 . 12 performed. The first and second arm 6 . 8th are about the first guide arm 14 on the base plate 20 movably attached. The rotatable attachment via a first pivot point 26 between the first holding arm 6 and first guide arm 14 , over a second holding fulcrum 28 between second support arm 28 and first guide arm 14 and over a first base pivot 32 between the first guide arm 14 and base plate 20 ,

To describe a fixed path of movement, the first arm is 6 still over a second guide arm 16 with the base plate 20 rotatably connected. The connection is made via a third holding fulcrum 30 between the first holding arm 6 and second guide arm 16 and a second base pivot point 34 between the second guide arm 16 and base plate 20 , These as described interconnected elements comprising the first and second support arm 6 . 8th , the first and second guide arm 14 . 16 and the fastener 4 can as a motor mechanics 36 considered, at least as far as a firm attachment to the first and second base point 32 . 34 he follows. Through this movement mechanics 36 becomes a fixed path of movement when opening and closing the flap 24 or the fastener 4 reached.

To keep closed and keeping open is now in addition to said movement mechanics 36 an auxiliary guide arm 38 with a connecting arm 40 intended. The auxiliary guide arm 38 is at an auxiliary pivot 42 rotatable on the base strut 22 and thus on the base plate 20 attached.

The connecting arm 40 connects the auxiliary guide arm 38 with the first holding arm 6 , The connections are made rotatable via a first connection pivot point 44 between auxiliary guide arm 38 and connecting arm 40 and second connection pivot point 46 between connecting arm 40 and first holding arm 6 ,

To keep the flap closed is a spring 18 at the base strut 22 and the connecting arm 40 attached. The feather 18 is under tension and pulls the connecting arm 40 in the direction of the spring force 48 to the basic strut 22 , The connecting arm, which is basically on the auxiliary guide arm 38 at the first connection pivot 44 supports, thus leading to a force 50 in the area of the second connection pivot 46 basically in the closing direction on the first arm 6 acts. The flap 24 is thereby kept in the closed state.

3 illustrated as opposed to 2 the hinge 1 in an open position. The flap 24 is here in a substantially horizontal position. The feather 18 is compared to the closed position according to 2 stretched something. Between the connecting arm 40 and the auxiliary guide arm 38 turns an angle 52 a, which is significantly greater than 90 °, about 140 °. The spring force 48 ' is compared to 2 due to the extension of the spring 18 Although increased, due to the large angle 52 but only worse the force over the second connection pivot point 46 on the first holding arm 6 exercise and also the very flat position of the first and second guide arm 14 . 16 causes the spring force 48 ' the flap 24 can not close against the weight.

It should be noted that according to 3 and basically according to 2 the spring force 48 ' respectively. 48 also a force on the auxiliary guide arm 38 exerts by putting the force on the connecting arm 40 acts on the auxiliary guide arm 38 in the area of the first connection pivot point 44 basically supported.

4 concerns a hinge for an upwardly opening flap 24 , It's basically the hinge 1 according to 4 according to the representation of 2 rotated by 180 °. Only the spring 18 is attached to another position, namely on the base strut 22 and the auxiliary guide arm 38 , The feather 18 exerts a spring force 54 on the auxiliary guide arm 38 out. This tensile force 54 is about the auxiliary pivot point 42 basically a thrust 56 converted at the first connection pivot point 44 on the connecting arm 40 acts. This thrust 56 is via the second connection pivot point 46 on the first holding arm 6 guided and leads to a force 58 in the closing direction on the holding arm 6 , The direction of this force 58 in the closing direction is determined both by the angle of attack 62 of the connecting arm 40 on the first holding arm 6 as well as the position of the two guide arms 14 and 16 certainly.

Illustrative is a parallelogram 60 by dashed lines in 4 located. This parallelogram 60 is defined by the first and second base fulcrum 32 . 34 and the first and third support fulcrums 26 . 30 , The parallelogram 60 is in the illustrated closed position of the flap 24 something about a state of motion mechanics 36 moved out in the this parallelogram 60 takes the special form of a rectangle. The invention makes this position of the parallelogram 60 use, so that the thrust 56 to the force 58 leads in the closing direction. This is favored by having one as an attack angle 62 Plotted angle between the connecting arm 40 and the first support arm 6 greater than 90 °. Thus, the spring force 54 ultimately be implemented in a closing force. The hinges are in accordance with 2 and 4 identical in their construction or are identical, except for the arrangement of the spring 18 ,

It should be noted that the flap 24 according to 4 opens up, basically alone by the weight in the closed position would remain. Nevertheless, the explained mechanism leads to a state in which the flap 24 harder than being pulled by the force of gravity alone in its closed position. As a result, for example, rattling can be prevented.

In 5 is the flap 24 now shown in its upwardly open position. The flap 24 This is approximately horizontal and the weight acting on them pushes the door 24 to close.

The feather 18 now applies a spring force 54 ' on the auxiliary guide arm 38 off, again over the first connection fulcrum 44 in a thrust 56 ' is redirected at the second connection pivot point 46 to a force 64 on the first holding arm 6 leads in the opening direction. The direction of force depends both on the angle of attack 62 ' between connecting arm 40 and first holding arm 6 , as well as the position of the parallelogram 60 ' from. The parallelogram 60 ' , is like the parallelogram 60 according to 4 defined and shown in dashed lines. The parallelogram 60 ' is here designed comparatively flat, compared to the configuration of the parallelogram 60 according to 4 , For the weight that hits the flap 24 For closing, the position of the hinge is unfavorable dar. The flap 24 can thus ultimately initiated by the spring force 54 ' be kept open. In particular, the position of the movement mechanics 36 and the wide open angle 52 ' are important for this. Through the wide open angle 52 ' stands up for the auxiliary management arm 38 with the connecting arm 40 a toggle effect. Would be the angle 52 ' At 180 °, the weight force on the flap could be 24 it works, shut up 24 even with a spring force 54 ' close to virtually 0 Newton. The angle 52 ' according to 5 has a value less than 180 °, so that closing is possible. However, the angle is 52 ' so big that the spring 18 still leads to a fairly large force, especially to such a large force 56 ' that closing the flap 24 counteracts.
