Description

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 or body. Furthermore, the invention relates to a furniture equipped with a hinge.

Hinges are well known. They are used in particular for the pivotable guiding of doors or flaps of a piece of furniture. Thus, a user can move the door or flap from an open to a closed position or vice versa. In the following, the term "flap" also includes elements such as doors.

Such a hinge is, for example, from the document EP 2 248 974 A2 known. The document relates to a hinge with a spring element provided on a movement mechanism which is intended to hold the flap of a piece of furniture in a closed and / or open state. The disadvantage here is that the spring element is provided on the respective arms in the movement mechanism and thereby is not exactly adjustable. Although the spring element can be hung in different position, but an exact adjustment of the bias is not possible. In addition, the movement mechanism of the hinge from the document EP 2 248 974 A2 an auxiliary guide arm, which is designed to be relatively large due to its function. Furthermore, the flap is held only by the spring force of a spring and is thus, for example, not protected during opening and closing in jerky movements and shocks and / or supported. Thus, it may come to an overuse of the spring through which their operation can be affected. This leads, for example, to the fact that the flap can not be held by the spring force and thus returns to a closed position without any action by the user. The user runs the risk of pinching his fingers.

The German Patent and Trademark Office has researched the following state of the art in the priority application: EP 0 952 290 A1 and EP 2 248 974 A2 ,

The invention is therefore based on the object to remedy or reduce at least one of the above-mentioned problems, in particular, the movement mechanism of a hinge should be improved, the hinge are made more compact and the safety of the user can be increased. At least an alternative solution should be proposed.

According to the invention 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 or body according to claim 1 is proposed. Such a hinge comprises a base member for securing the hinge to the body, a fastener for securing the hinge to the flap, a moving mechanism for guiding the fastener on a path of travel, the trajectory relative to the base member being dictated by the configuration of the moving mechanism is fixed. Furthermore, the hinge comprises a spring element for providing a bias voltage for holding the flap in a closed and / or open state and provided on the base member adjusting device for adjusting the bias of the spring element. In this case, the spring element is fastened with a first side to the movement mechanism and with a second side to the adjustment device.

The trajectory is fixed with respect to the base element and thus when properly installed in relation to the piece of furniture. Such a movement mechanism can basically be designed in different ways. The base element is, for example, provided as a simple plate which is fastened to the body or body of the piece of furniture. Alternatively, the base element is formed from a plurality of, for example, frame-like elements which are prepared for connection to one another and / or at least one of the frame-like elements is prepared for connection to the body or body of the furniture. In this case, the individual elements can be designed so that they are provided at predetermined areas at a predetermined distance from the body or the body of the furniture, namely at areas where the movement mechanism provided, in particular is attached. The distance is in particular designed so that the movement mechanism can move freely on the non-attached to the base member areas.

The fastening element for fastening the hinge to the flap in this case has at least one flap pivot on which, in particular, the movement mechanism of the hinge is movably attached to the fastening element. Such a flap pivot point can be arranged, for example, on a flange provided on the fastening element.

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 be based on a furniture or the like. pull and hold a flap in the direction of the furniture when it is closed 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 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 force holds the flap without the spring prevents it. Of course, when dimensioning, it should also be taken into account in general how many hinges are used per flap. Usually, two hinges are assumed.

Characterized in that the spring element is attached to a first side of the movement mechanism and with a second on the adjusting device, the bias of the spring element can be adjusted exactly. Preferably, the adjustment device is prepared for varying a length of the spring element. As a result, the force required to open the flap can be adjusted. The hinge is thus adaptable to different flaps. The first and / or second side of the spring element is, for example, hook-shaped. Then, the first and / or the second side are suspended in an opening provided on the movement mechanism and / or the adjusting device therefor. Alternatively, the first and / or second side of the spring element is formed like an eye. Then, the first and / or second side are suspended in a provided on the movement mechanism and / or the adjustment device therefor hooks or the like.

Preferably, the adjustment device is attached to the base member. As a result, the spring element on the side where it is provided or fixed in the adjusting device is adapted to the movement mechanism and correspondingly to an upwardly or downwardly opening flap.

In a further embodiment, the adjusting device has an adjusting screw and a spring tensioner for fastening the spring element. In this case, the spring tensioner may be formed as a kind of arm on which the spring element is provided, in particular the second side of the spring element, for example, is mounted. About the adjusting screw of the spring compressor according to the intended bias set the spring element. At a high intended bias the spring compressor is tightened accordingly, so that the spring element is pulled apart. After tightening the spring tensioner in a predetermined position, the spring element is firmly clamped on this side and can only be moved over the provided on the movement mechanism side, namely by pressing the corresponding flap.

In addition, a hinge is proposed, which comprises a base element for fastening the hinge to the body, a fastening element for fastening the hinge to the flap and a movement mechanism for guiding the fastening element on a path of movement, wherein the movement path with respect to the fastener is fixed by the design of the movement mechanics. Furthermore, the hinge comprises a spring element for providing a bias for holding the flap in a closed and / or open state. The movement mechanism includes first and second support arms for holding the fastener, a first spring arm for securing the spring member in a first position, and a second spring arm for securing the spring member in a second position. Furthermore, the movement mechanism comprises a first guide arm which is rotatably connected to the base member at a first base fulcrum, to the first support arm at a first support fulcrum and to the second support arm at a second support fulcrum. In addition, the movement mechanism comprises a second guide arm rotatable with the base member at a second base fulcrum, with the first support arm at a third support fulcrum and with a link arm for connection to the first or second and / or a mediate arm with the second and first spring arm, respectively connected is.

If the flap is moved from a closed to an open state, the fastener moves forward as intended, ie away from the body or body of the furniture from a vertical to an approximately horizontal position. The two retaining arms are thereby pushed forward in a substantially constant first attitude by means of the two guide arms. The two guide arms are rotatably attached via a respective base pivot point to the fastener. The second guide arm moves at an angle of about 90 °. The movement mechanism is designed so that the connecting arm connected via a connection pivot point with the second spring arm is also moved forward. Thereby, preferably, the first spring arm is pivoted about a base pivot point, that the spring element attached thereto is stretched, what for a downwardly opening flap is provided. The spring element is thus pulled apart, that is moved against the spring force. In a downwardly opening flap, the spring element is attached to the second spring arm and is compressed in the described movement or may contract slightly. Thus, the spring element is slightly compressed, that is moved in the direction of the spring force, because the second spring arm on which the spring element is mounted, according to a further base pivot point pivots.

Preferably, a brake element for controlled braking during opening and closing of the flap is provided on the middle arm and / or the brake element is connected via the middle arm with the first and / or second spring arm. In this case, the brake element ensures in particular the controlled opening and closing of the door of the furniture. Thus, the flap itself is protected from overuse in the end positions, ie in the open or closed state. Moreover, the controlled opening and closing prevents pinching of the user's fingers. The brake element intercepts in particular jerky movements and / or shocks, so that they do not affect the movement mechanism in their functioning. The spring element can thus be supported by the brake element. The braking element can also be designed as a damping element.

In another embodiment, the flap in the first position of the spring element is prepared for use in opening upwards or the flap is prepared in a second position of the spring element for use in opening downwards. In this case, the spring element is, for example, in the first position with the first side attached to the first spring arm and with the second side attached to the adjustment device. In the second position, the adjusting spring is fixed in this case with the first side on the second spring arm and with the second side of the adjusting device. The first and second positions can also be defined vice versa.

In a preferred embodiment, the first and second spring arm is rotatably connected to the base member and / or provided on the base member additional arm. In this case, either the base element at this point an increase, so a distance to the body or body of the furniture, so that the movement mechanism can move freely. When using an additional arm of this particular is attached to the base member that he produces such an increase.

Preferably, the fastening element comprises at least one connecting portion, in particular a plate for connecting to the flap, a main body with at least one flange for fixing the movement mechanism and a latching element for connecting the main body to the connecting portion, in particular to the plate. Thus, for example, at first the at least one plate is connected to the flap, in particular screwed. The main body with the at least one flange is connected via the locking element by snapping with the plate. Thus, a quick assembly and disassembly is possible. For example, a flap can thus be provided with two slits, each with a plate, in the intended use of two hinges. This allows the flap to be used flexibly as an upwardly or downwardly opening flap. By such a pre-assembly and the simple snapping many furniture can be built in no time.

In a further embodiment, at least one in particular adjustable and / or elastic stop element for catching a closing movement of the flap is provided on the base element. In this case, the stop element is provided in particular as provided with a damping material screw. Due to the adjustability of the hinge is adaptable, for example, to different flap thicknesses.

In a further embodiment, the hinge is prepared, when used as intended, to hold the flap in an open and closed position. The same hinge can be used. Only the position of the spring element must be changed.

According to the invention a furniture is also proposed with a body with at least one flap, wherein the flap is secured by means of at least one, preferably two hinges according to one of the preceding embodiments of the body. Such furniture may be, for example, a shelf element or a cabinet element, which should be opened depending on the installation position up or down. Another example of a piece of furniture is a so-called "low-board" or "side-board".

The figures contain partially simplified, schematic representations. In part, identical reference numerals are used for the same but possibly not identical elements. Different views of the same elements can be scaled differently.

FIG. 1 shows a hinge 1 schematically in a properly closed position. The hinge 1 has a base element 30, which is formed from a first partial element 31 for connection to a body or body of the furniture, a second partial element 32 and a third partial element 33. The first sub-element has for attachment to the body or body of the furniture five holes 25 through which screws can be used, which are connectable to the body. On the first sub-element 31, a second sub-element 32 is arranged, which is partially connected to the first sub-element 31 and partially to the third sub-element 33, that is arranged between the first sub-element 31 and the third sub-element 33. Above this, the third subelement 33 is arranged. The third sub-element 33 is designed so that it partially at a distance from the first or second sub-element 31, 32 areas for connecting with, for example. The movement mechanism 26 has. At This base member 30, the movement mechanism 26 is rotatably mounted on the base pivot points 11, 12, 20 and 21. The fastening element 70 is attached to the movement mechanism 26 via a first and a second flap pivot point 13, 14 for connection to the flap. The fastener 70 is in a substantially vertical position. About the first and second flap pivot 13, 14, the fastener 70 is movably connected to the first and second support arm 3, 4. The first and second holding arms 3, 4 are connected via the first guide arm 5 via a first and a second holding pivot point 15, 16. The first holding arm 3 is additionally rotatably connected via a third holding pivot point 27 with the second guide arm.

A connecting arm 7 connects the movement mechanism 26 with a first spring arm 8 via a middle arm 10 and with a second spring arm 9. Between the middle arm 10 and the second spring arm 9, a braking element or damping element 24 is arranged to support the spring element 2.

For holding the flap closed, a spring 2 is attached to the setting device 40 and the first spring arm 8 as an exemplary embodiment of a spring element. The spring 2 is here under tension and pulls the first spring arm 8 in the direction of the spring force 50 to the adjustment device 40th

The base element 30, the first partial element 31 and the second partial element 32 can be adjusted or positioned relative to each other. For this purpose, the second sub-element 32 can be adjusted relative to the first sub-element 31 by means of a vertical adjusting means 34. For this purpose, the vertical adjusting means 34 has a vertical receptacle 35 fixedly connected to the first subelement 31, in which a vertical adjusting means 36 is accommodated, which is designed here as a vertical adjusting screw 36. By actuating the vertical adjusting means 36, that is to say by turning the vertical adjusting screw 36, the second subelement 32 can thus be moved relative to the first subelement 31. This moves the entire movement mechanics, which can thus be adjusted in their vertical position, ie in their height.

For an adjustment or adjustment of the movement mechanism 26 in their direction in the depth of the furniture to which the hinge 1 is to be attached, a Tiefenverstellmittel 37 is provided, which in the Fig. 1 is partially covered by the second spring arm 9 and therefore in the Fig. 2 is better to recognize. This depth adjustment means 37 provides a relative adjustability of the base member 30 relative to the second sub-element 32 and thereby an adjustability of the movement mechanism 26 in this direction. The depth adjustment means 37 has for this purpose a depth receptacle 38, which has a depth adjustment means 39, which is designed here as a depth adjustment screw 39. By actuating the Tiefenverstellmittels 39 and turning the depth adjustment screw 39, a relative movement between the base member 30 and the second sub-element 32 is achieved and thus allows adjustment in the depth direction.

Thus, arranged on the fastener 70 flap in height and in depth, based on the corresponding furniture, be adjusted. A third, namely lateral adjustment results from the design of the fastener 70, which later in connection with the FIGS. 7 and 8 will be explained.

FIG. 2 shows in contrast to FIG. 1 the hinge 1 in an open state, ie with an open fastener 70, which is in a substantially horizontal position. The spring 2 is compared to the closed position according to FIG. 1 stretched. In this case, the adjusting device 40 remains at the previously set position. The spring arm 8 has moved in the direction of the spring force 50. The spring force 50 is compared to FIG. 1 has risen due to the extension of the spring 2, wherein the movement mechanism is formed so that the spring force 50 is unable to close a flap in this fully open position against the weight. In this case, a closing movement against the force of gravity is supported by the spring force 50. The in FIG. 2 shown opened state shows the maximum opening movement, which is limited by the movement mechanism.

FIG. 3 shows a hinge 1 for an upward to the opening of the flap 60. Basically, the hinge 1 according to FIG. 3 according to the representation of FIG. 1 , only rotated by 180 °. In contrast to FIG. 1 the spring 2 is not suspended in the first spring arm 8, but in the second spring arm 9. In addition, the spring 2 in contrast to the spring in FIG. 1 already stretched to its maximum voltage.

It should be noted that the hinge according to FIG. 1 can be used for the use of an upwardly opening flap. Only the spring 2 must be changed in position for this purpose, namely instead of being fixed to the first spring arm 8 on the second spring arm 9. Thus, the hinge is not limited to an application form, but can be used in various furniture.

FIG. 4 shows the hinge 1 according to the FIG. 3 in an open state of the flap 60. The flap 60 is arranged approximately horizontally. The second spring arm 9 has moved around the third base pivot 20 in the direction of the flap 60. Thus has the spring 2 contracted a little. As a result, the spring 2 exerts a force on the movement mechanism 26, which holds the flap 60 in this open position against gravity. To damp a movement of the movement mechanism 26, the braking element or damping element 24 is arranged between the second spring arm 9 and the middle arm 10.

FIG. 5 shows a shelf member 100 having two side walls 101, a bottom 102, a top wall 103 and a flap 160. At the four corners of the control element 100, a foot 104 is attached in each case. The flap 160 has a handle 161 through which the flap can be opened when pulled on it. On the side walls 101, a hinge 1 is attached in each case. The respective fastening element 70 of the hinge 1 is fastened to the flap 160. By the hinge 1, the flap 160 is held in the open position against the weight.

Furthermore, in FIG. 5 three hole pattern 105 on the inside 106 of the side wall 101 to recognize. These bore patterns are prepared so that the hinge 1 can be attached to the sidewall 101 at different positions as needed. As a result, the shelf element 100 can be used flexibly.

FIG. 6 shows a shelf element 100, in which the two flap hinges 1 in a second position, ie in a position in which the flap 160 is opened downward, are mounted. To accomplish this, the two flap hinges 1 have been attached to one of the lower bore patterns 105. In addition, the spring 2 of the hinge 1 has been fastened on its one side to the first spring arm 8.

FIG. 7 shows a fastener 70 having a main body 73 and as connecting portions a first plate 71 and second plate 72. The first and second plates 71, 72 are connected to each other via the screws 76. The main body 73 is connected to the first and second plates 71, 72 via a detent member 80. On the main body 73, a flange 74 is provided with holes 75 for connection to a movement mechanism of a hinge or the flange 74 is formed as part of the main body 73.

FIG. 8 shows a sectional view AA of the fastener 70 from FIG. 7 , Here are in addition to FIG. 7 To recognize holes 77 through which the first plate 71 can be attached to a flap.

The screws 76, which are in the FIGS. 7 and 8 are shown, each received in an approximately oval or elongated opening 78. As a result, an adjustability or adjustability of the first plate 71 relative to the second plate 72 and thereby to the main body 73 is made possible. For this purpose, the screws 76 can be loosened a little and then moved, namely according to Fig. 8 into or out of the drawing plane. As a result, the position of a flap in the lateral direction can be adjusted when it is attached to the first plate 71.

The proposed hinge thus enables an adjustability or adjustability of a flap received therein in basically three directions, namely in basically three Cartesian directions. The vertical adjustment means 34 allows height adjustability, the depth adjustment means 37 provides depth adjustability, and the screws 76, which may also be formed as other lateral adjustment means, provide lateral adjustability.

FIG. 9 shows the section B of FIG. 8 in an enlarged view. Here, in particular, the locking element 80 can be seen. The locking element 80 is inserted between the flange 74 and the main body 73 and the second plate 72. In this case, the latching element 80 has a closing element 81, an elastic element 82 and a pin 83. The elastic member 82 is bent around the pin 83 and clamped with two protruding flanks between the closing member 81 and the main body 73 and flange 84. In addition, the locking element 80 is hooked to the second plate 72. The pin 83 is as in FIG. 7 can be seen, provided in the main body 73. By this connection, thus, the main body 73 can be easily attached by hooking or snapping on the second plate 72. By the elastic member 82, the connection can be solved by pressing against the closing element 81 without tools.
