Description

The present invention relates to a hinge, in particular for furniture, with a hinged to a door or flap hinge part, which is mounted on at least one lever pivotally mounted on a side part, wherein the side part is held on a mountable to a furniture body mounting plate, and at least one suit spring to bias the hinge part in a tightening area to a closed position.

The EP 1 711 674 discloses a hinge having a fixable on the furniture body side part and a pivotally mounted hinge part. On the lever mechanism for pivoting the hinge part, a spring is mounted, which pushes the hinge part in an opening area sliding in the opening direction. On the one hand, it can not be ruled out that the hinge hits the uncontrolled up to a maximum open position due to the pushing pressure of the spring. On the other hand, doors with greater weight can be moved only insufficiently or only slowly in the opening direction, which makes it difficult to cooperate with a latching mechanism for locking the door element in a closed position.

It is therefore an object of the present invention to provide a hinge that ensures easy handling when opening and closing and can be adapted to different applications.

This object is achieved by a hinge with the features of claim 1.

According to the invention, the hinge has both at least one tightening spring (closing spring) in order to bias the hinge part into a closed position in a tightening area and at least one opening spring which pretensions the hinge part in an opening area in the opening direction. As a result, the springs can be matched to one another in such a way that optimum support of the user when opening and closing a door or a flap is made possible. The spring characteristics and the angle range for the attraction area and the opening area can be optimized for the respective application.

Preferably, the attracting region and the opening region at least partially overlap. Thereby, the high voltage of the opening spring from the closed door or flap position is mitigated by the tightening spring, so that an opening operation can be relatively uniform up to a desired opening angle. This angular range, which is for an opening support, is adjustable on the opening spring. Of course, it is also possible to set the opening spring so neutral that the hinge closes with its tightening spring and only the effect of the tightening spring is realized. The combination of tightening and opening spring can also act in different areas, for example, to realize a self-tightening, which allows opening support on reaching a certain opening position of the hinge part to which the opening spring can be adjusted via a pressure point mechanism that a door or flap in a predetermined opening position is pressed, for example, in an opening angle of 90 °.

According to a further embodiment, the spring force of the opening spring is adjustable. As a result, an adjustment of the respective spring force, with superposition of the two springs and the resulting spring force, are made possible. In addition, the range of action of each spring can also be adjusted.

Preferably, in a closed position, the opening spring biases the hinge part in the opening direction, wherein the spring force of the opening spring is greater than the spring force of the tightening spring. In this case, for example, a latching mechanism is provided to fix the hinge part or an associated component in a closed position. Such latching mechanisms are used in particular in handle-less doors, which are unlocked by pressing the door, so that then the opening spring pushes the door by a certain angular range.

The opening spring is preferably designed as a compression spring, for example as a helical spring, which may be accommodated protected within the hinge part. Furthermore, the opening spring can be arranged around a linearly movable guide element. The guide element may comprise a pin which is displaceably mounted in a sleeve, so that a good linear guide is ensured by the guide element. Instead of an inner guide, a tubular outer guide can also be arranged around the spring.

For a compact construction of the hinge, the guide element can be supported on one side on the side part and on the opposite side on a deflecting element, wherein the deflecting element is rotated during a pivoting movement of the hinge part. As a result, the change in length of the guide element can be optimally adjusted by turning the deflecting element, wherein the guide element can also be fixed at different positions of the deflecting element in order to effect a corresponding change in the spring characteristic.

According to a preferred embodiment, the opening spring and the tightening spring are adjusted so that the hinge part over an opening range from any angle to max. 110 °, is pressed in the opening direction. Ideal are 25 °, because then door does not disturbing swinging into the room purely and on the other hand, the angle is large enough to open the door, for example, with the back of the hand, for example, when plates are being worn. As a result, after unlocking a latching mechanism, the hinge part can be pivoted together with the door over a large opening area.

Furthermore, by the combination of the two oppositely acting springs an equilibrium position can be specified, the door size and door mass is independent. The door is always leveled in the same opening angle, the opening angle is adjustable by the opening spring.

In order to optimally adjust the spring force of the opening spring and / or the tightening spring, at least one adjusting element is preferably provided in order to adjust the length of the spring or the angle of rotation. In this case, the opening spring can also be removed from the hinge when required, so that the hinge can be easily converted to a hinge with only one closing spring. In addition, the hinge can be equipped with a damper instead of an opening spring, so that a high degree of flexibility is available.

A hinge 1 includes a hinge part 2 at a door 3 a piece of furniture or another component. The cup-shaped hinge part 2 is pivotable on a side part 4 held that over a mounting plate 5 on a furniture body 6 or another component is fixed. The side part 4 can have a first adjustment mechanism 35 and a second adjustment mechanism 36 relative to the mounting plate 5 be movable to the position of the door 3 relative to the furniture body 6 to be able to adjust. About the adjustment mechanisms 35 and 36 can be an orientation of the side panel 4 done in two or three different directions.

The hinge part 2 is over a support lever 7 and a guide lever 8th on the side panel 4 pivotally mounted, wherein the support lever 7 over an axis 9 on the hinge part 2 and an axis 10 on the side panel 4 is rotatably mounted. The guide lever 8th is about an axis 11 on the hinge part 2 and an axis 12 on the side panel 4 rotatably mounted. The guide lever 8th includes adjacent to the axis 12 a boom 13 at which a rotation axis 14 for a lever 15 is trained. The lever 15 is at the opposite end on an axis 16 on a deflecting element 17 rotatably mounted. The deflecting element 17 is on the side panel 4 around an axis 18 stored.

The deflecting element 17 includes a bolt 19 that with a guide element 20 is coupled. The bolt 19 and the axis 16 are on opposite sides to the axis of rotation 18 arranged.

The guide element 20 includes a pin part 21 that with the bolt 19 is connected and a pen 23 which is in a sleeve 24 is included. The pen part 21 also has a radially protruding ring 22 on, on which an opening spring 27 supported as a coil spring between the pin part 21 and the sleeve 24 is held. On the sleeve 24 is an annular projection 25 formed, at which one end of the opening spring 27 is supported.

The sleeve 24 is at the from the pen part 21 opposite end with a bolt 26 coupled, the hinge part 4 is stored.

The opening spring 27 pushes the hinge part 2 via the interposition of the deflecting element 17 , the lever 15 and the guide lever 8th in Opening direction. In contrast, acts a suit spring 30 in the closing direction. The suit spring 30 includes a middle wound portion and a first leg 31 holding a pen 32 is supported. Further, a second leg 33 the suit spring 30 on the axis 18 or another component supported to the hinge part 2 to pretension in the closing direction.

The side part 4 is also over a hook 38 and a spring-loaded mounting hook 37 on the mounting plate 5 fixed.

In 2 is the door 3 shown in a slightly open position. By pivoting the door 3 is the pen 23 from the sleeve 24 partially pulled out, leaving the opening spring 27 was relieved by a certain share. The suit spring 30 was pivoted, however, with the thighs 31 and 33 were rotated by an angle relative to each other.

By a further opening movement of the door 3 can the in 3 shown position in which the door 3 is opened at about 90 °. The opening spring 27 was extended even further, with the pin part still further from the sleeve 24 was moved out, so that the opening spring was further relaxed. Will the door 3 now moved in the closing direction, the opening spring must 27 be compressed while starting from a certain opening angle of the door 3 the suit spring 30 takes effect and pushes the door into a closed position. The force of the opening spring 27 but is greater than the force of the suit spring 30 , so that in a predetermined angular range, for example between 0 ° (closed position) and 50 °, the opening spring 27 the door 3 in the opening direction presses. In the closed position, the door 3 held by a locking mechanism, not shown. The locking mechanism can be made by pushing the door 3 be unlocked.

In 3 is on the sleeve 24 an annular end portion 25 ' formed on which a run-on slope 28 is trained. This allows the guide element 20 easier on the bolt 26 to be assembled.

In 4 is a diagram of the spring forces relative to the opening angle of one with the hinge part 2 shown coupled door. The spring force of the opening spring 27 decreases with larger opening angle and is negligible at an opening angle of 55 °. The suit spring 30 provides torque to the hinge part 2 in the closing direction, wherein the largest torque is generated in a range between 15 ° and 30 °, while the torque from about 55 ° is also negligible. This results in the hinge part 2 a resultant torque that causes it to hinge up to an angle D that is in a range between 15 ° and 25 ° 2 is pressed in the opening direction while the hinge part 2 is pressed in a range between D and about 55 ° in the closing direction. When the door is closed, this is assisted to the point D by the resultant of the springs and only in a closing range between 0 ° and the point D, the user must overcome the resulting opening force. The point D can by the arrangement of an opening spring 27 and a suit spring 30 be freely set in many areas for different applications.

In 5 is the guide element 20 shown in which the spring force of the opening spring 27 was increased. The opening spring 27 is at the pen part 21 on the protruding ring 22 supported and on the opposite side is between the annular projection 25 and the end of the opening spring 27 a ring 40 arranged, for example a spring ring, so that the opening spring 27 more compressed and shortened in length. As a result, a greater spring force acts on the pin part 21 and via further mechanical transmission elements on the hinge part 2 a larger torque in the opening direction.

In the 6A and 6B is another adjustment for the guide element 20 shown, wherein on the annular projection 25 the sleeve 24 a first channel 41 for receiving the bolt 26 and a second channel 42 for receiving the bolt 26 are provided. The channels 41 and 42 are arranged at an angle to each other, in particular at right angles, wherein the channel 41 has a greater depth X than the channel 42 , The sleeve 24 can be offset by 90 ° on the bolt 26 be mounted so that optionally the deeper channel 41 or the channel 42 engaged with the bolt 26 arrives. Accordingly, the distance between the annular projection 25 and the lead 22 at the pen part 21 shortened or lengthened by the amount "X", so that the length L1 of the opening spring 27 and thus the spring force also changes accordingly.

In 7 is shown a further embodiment for changing the spring force, wherein on the sleeve 24 in an area adjacent to the disc-shaped projection 25 a thread 44 is trained. At the thread 44 is a wheel 45 arranged with an internal thread, which can be adjusted by turning in the axial direction. On the wheel 45 is an end of the opening spring 27 supported, while the opposite end back to the annular projection 22 of the pen part 21 is supported.

In 8th is another way to adjust the length of the opening spring 27 shown, this time on the pen part 21 a threaded section 46 is formed, on which a thumbwheel 22 ' is arranged with an internal thread. By turning the adjusting wheel 22 ' An axial adjustment can be made so that the opening spring 27 accordingly by the thumbwheel 22 ' compressed or relaxed. The length between the bolt 19 and the bolt 26 remains constant.

The in the 5 to 8th Of course, adjustment mechanisms shown can also be combined with each other, and it is possible, other adjustment mechanisms for changing the bias of the opening spring 27 provided.

In addition, the force of the suit spring can also 30 be adjusted by appropriate adjustment mechanisms.
