Description

The invention relates to a door hinge with the features of the preamble of claim 1.

Furthermore, a door with a door hinge and a shower partition with a door should be specified.

Such door hinges are already part of the prior art and are used for example in the EP 1 574 649 A2 , of the US 4875252 A and the US 2,437,192 A shown. These hinges have several legs and are thus able to absorb high forces despite their compact design. Furthermore, by means of such hinges larger opening angles can be realized, which is advantageous, for example, in shower cubicles. It can thus be achieved by a compact hinge, a large opening angle with a large load capacity. However, the compactness and complicated structure make it difficult to directly install a return device for automatically swinging the hinge back into a preferred position. Hinges of this type often do not have a simple, long-term, internally-mounted reset unit to automatically return the hinge to a preferred position. Furthermore, the restoring units are often too weak to be able to move the heavy weight of a door, in particular glass door.

The object of the invention is to avoid the disadvantages described above and to provide a comparison with the prior art improved door hinge, a door with a door hinge and a shower partition with a door.

This is achieved in the door hinge according to the invention, in the door according to the invention and the shower partition according to the invention by the features of the characterizing part of claims 1, 14 and 15.

Due to the fact that the first guide element is connected to the first fitting part by at least one first energy store and the second guide element is connected to the second fitting part by at least one second energy store, a provision of the fitting parts relative to one another is achieved in a preferred position. For example, the door hinge pivots automatically after opening the door attached thereto in a closed position.

If the first guide on the first fitting part and the second guide are arranged or formed on the second fitting part, the result is a compact design of the door hinge. In the guides, the guide elements are mounted, said guide elements are longitudinally movable in the guide in a direction transverse to the axis of rotation. Through these guides a larger swing angle is achieved on the door hinge, more articulated levers or legs can be saved. The guide also serves as a force and distributes the forces of the articulated levers on the fitting parts.

It has proved to be particularly advantageous that the energy accumulators are designed as tension springs. These can be arranged by simple means between the fitting parts and the guide elements. When pivoting between an open and a closed position of the hinge, the tension springs are tensioned accordingly and ensure a return to a preselected position.

If the tension springs at the ends receptacles for engaging in the guide elements and at the opposite ends receptacle for fixing a locking member, so the installation of the springs is easy. Optionally, a spring can be replaced after damage. It can also be provided that z. B. at very heavy doors that are attached to the door hinge, stronger springs can be installed or can be retrofitted.

If the force accumulator pull or push the guide elements along the guide, preferably pull, so the way for the energy storage and thus also for the guide elements is limited by the guide and predetermined. By the guide can thus be precisely defined, in which area is the open position and also the closed position of the hinge. In addition, the energy storage acts almost parallel to the direction of the guide, is thus aligned almost parallel to the guide and thus edged or arranged to save space in the door hinge. By this parallel arrangement for guiding and the force acting parallel to the guide force of the energy storage and lateral forces are prevented, which may arise for example by the action of the energy storage when pivoting the door hinge.

When the first articulated lever is pivotally connected to the second fitting part via a first fixing element and the second articulated lever is pivotally connected to the first fitting part via a second fixing element, a hinge with two fitting parts, which are connected to one another via two articulated levers, is produced. The two articulated levers result in a larger opening angle of the hinge in a more compact design. When the hinge levers are rotatably connected to each other by a main pivot pin about the axis of rotation, so the pivoting of the door hinge on the axis of rotation takes place, but the fitting parts are also supported on the fixing elements and a larger opening angle is made possible by the guides. The axis of rotation ensures sufficient stability on the hinge. The axis of rotation defines the actual pivot point of the door when it is moved between an open and a closed position. Since the pivot point when opening the hinge from the fitting elements, thus the door is removed from the frame. By removing the door from the frame, an enlarged gap between the door and the frame generated as soon as the door is opened. By this enlargement of the gap thus z. B. seals, which are located between door and frame, spared. If, for example, a seal is fastened to the door frame, it only comes into effect when the door is closed and is no longer contacted by the door when the door is opened. If the gap did not increase, the door between open and closed position would rub permanently on the seal and damage it over a longer period of time. Further, by enlarging the gap, the door and the frame in the area of the gap can be more easily cleaned since it becomes accessible.

If the articulated levers are arc-shaped, wherein at one end of the arcuate articulated lever, the guide element is arranged, preferably fastened and the fixing element is arranged at the opposite end of the arcuate articulated lever, then an even more compact hinge can be formed over the arcuate design. If the articulated levers were formed in a straight line, the size of the hinge would increase. The arcuate design prevents the guide elements collide with the articulated levers early on, which would prevent further opening of the door hinge. Thus, not only the size is a significant advantage, but also the opening angle, which is achieved by arc-shaped hinge lever.

If a receptacle for attaching the main rotary pin is provided between the guide element and the fixing element along the arcuate articulated lever, the articulated levers are connected to each other and rotatably connected to each other.

If the guide elements and the fixing elements are pin-shaped and engage the ends of the pins in the guides, a simple construction of the door hinge. Pins are easy to insert into elements and connect to elements - only one hole is needed to insert the pins into the hinge levers. Furthermore, the leadership can be simply as Longitudinal groove are formed, there are no complicated shapes necessary, which is also reflected in a compact design.

If at least two first toggle levers are arranged on the first fitting part and thus two second toggle levers are arranged on the second fitting part and the toggle levers are alternately offset from each other along the axis of rotation, the fitting parts are not only connected to one another via a hinge lever assigned to the fitting part, but via several , As a result, a better distribution of force is achieved, the door hinge can thus be used for heavier doors. A leaching or knocking out of the articulated connections is also prevented because larger receiving areas for the pins are achieved with it.

Fig. 1 shows a door fitting 100 without a cover. The cover was up in all drawings Fig. 12 omitted for simplicity in order to better illustrate the function of the hinge 100. The hinge 100 has a first fitting part 1 and a second fitting part 2. At the first and second fitting part 1, 2 are fastening sections B for fixing a cover, which in the Fig. 1 is not apparent. This can by means of suitable measures, such as. B. clips or other fastening means on the first and second fitting part 1, 2 are attached. About the fixing member 11, 12, the fitting parts 1, 2 on the in Fig. 1 not apparent articulated lever 17, 18 connected to each other. The pivoting of the hinge 100 takes place via the axis of rotation D. The first cover element 14 is located on the first fitting part 1 and is connected via fastening means 16 with this. So also the second cover member 15, which is connected to the second fitting part 2. The cover elements 14, 15 conceal and store the articulated levers 17, 18, furthermore they guide and protect a portion of the energy accumulators 80, 81.

Fig. 2 shows the door hinge 100 for simplicity without covers 14, 15. The in the assembled state in the covers 14, 15 engaging fixing 11, 12 are now free - these are rotatably mounted in the covers 14, 15 normally. Furthermore, the guide elements 21, 22 longitudinally movably mounted in a guide located in the cover 14, 15, which in the 3 and 4 is explained in more detail. The at least one first energy accumulator 80 is connected to the first fitting element 1 via a locking element 13. The other end of the energy accumulator 80 is connected to the guide member 21. So also on the second fitting element 2, which also has at least one locking element 13 to connect the energy storage 81 with the fitting element. The other end of the energy accumulator 81 engages in the guide element 22 a. Thus, when the first fitting part 1 is pivoted relative to the second fitting part 2 about the axis of rotation D, clamping of the force accumulators 80, 81 is achieved. Subsequently, the door hinge 100 due to the tensioned energy storage 80, 81 the desire to return to this original shape, as it is in Fig. 2 is pictured. The Fig. 2 shows the door hinge 100 in a closed position S. The rotation axis D is formed by a main pivot pin 3, which connects the articulated levers 17, 18 with each other.

Fig. 3 shows the first cover 14 and the second cover 15 in a bottom view. Therein, the articulated levers 17, 18 are arranged offset to one another and mounted on the fixing elements 11, 12. The detail "A" is in Fig. 4 explained in more detail.

Fig. 4 shows the detail "A" from the Fig. 3 , The guide element 21, 22 thereby moves in a guide F1, F2. When the articulated levers 17, 18 are pivoted relative to one another, the guide element 21, 22 moves along the guide F1, F2. Arranged on the guide element 21, 22 is the receptacle AF for engaging the force accumulator 80, 81 on the guide element 21, 22. In the course of the movement of the guide element 21, 22 in the guide F1, F2 via the immediate contact to the force accumulator 80, 81 via the recording AF of the energy storage 80, 81 relieved or stressed.

Fig. 5 shows an arrangement of articulated levers 17, 18, which are interconnected via a rotation axis D. The articulated levers 17, 18 are offset from each other and arranged alternately along the axis of rotation D. For example, the arch of the articulated lever 17 protrudes on the left side and the arch of the articulated lever 18 on the right side. At one end of the articulated lever 17 is the fixing element 12, which is in communication with the second fitting part 2. At the opposite end is the guide element 21, which is in communication with the first guide F1 on the first fitting element 1. The second articulated lever 18 also has the guide element 22 at one end, which is connected to the second guide F2 on the second fitting part 2. The force accumulators 80, 81 exert a pulling force on the guide elements 21, 22 and pull them into an extended position. The guide element 21 is guided at both ends by the first guide F1, F1 '. So also the second guide member 22, this is also guided with both ends in the second guide F2, F2 '.

Fig. 6 shows the arrangement of the articulated levers 17, 18. In this perspective, the main pivot pin 3 is visible, which connects the articulated levers 17, 18 with each other. The first articulated lever 17 is, as in the Fig. 5 already recognizable, layered. So also the second articulated lever 18. By this layered structure, a stable body can be achieved, the production of this body is easier to implement than, for example, a casting or a milled part. Each individual layer can be punched out, for example, in a sheet-metal punch, and subsequently a dimensionally stable, layer-strong body can be built up by superimposing the layers on top of each other. The articulated levers 17, 18 are identical in shape, are arranged along the axis of rotation D only differently aligned with each other, so that a hinge lever 17 extends in a different direction than another articulated lever 18th

Fig. 7 shows a schematic representation of the door hinge 100. In this case, the guide F1 and F2 directly in the fitting 1, 2 arranged, as well as the fixing elements 11, 12. This thus shows a simplified illustration and also another embodiment of the door hinge 100th In Fig. 3 4 shows how the guides F1 and F2 are located in the cover element 14, 15. So also the fixing elements 11, 12. In a simpler variant, it would be possible to arrange the guides F1, F2 directly in the main body of the fitting element. The attachment points through the fixing elements 11, 12 could be located directly in the main body of the fitting part 1, 2. The Fig. 7 shows the closed position of the hinge 100. By the force storage 80, 81, the guide elements 21, 22 are pulled along the guide F1, F2 in the end position. By this tensile force, the articulated levers 17, 18 are stretched.

The Fig. 8 shows how the door hinge 100 is opened. Shortly after the opening of the force accumulator 80, 81 begins to tension. By contact with the guide elements 21, 22, this tensile force is transmitted to the articulated levers 17, 18. The guide elements 21, 22 move linearly along the Guides F1, F2. The pivoting of the hinge 100 takes place about the axis of rotation D. It is also apparent how the fitting parts 1, 2 spaced from each other. The gap between the fitting elements 1, 2 increases with increasing opening angle in the direction of the open position O. From a certain opening angle, the first hinge lever 17 collides with the first fixing element 11 and the second hinge lever 18 with the second fixing element 12. If this case occurs, could be no further opening of the hinge 100. However, the guides F1, F2 prevent this and further movement of the fitting elements 1, 2 relative to one another in a larger opening angle is made possible. The articulated levers 17, 18 no longer move relative to each other. These remain in position, since the articulated levers 17, 18 abut on the fixing elements 11, 12. Thus, it can be said of a two-stage movement, in a first opening area, the hinge 100 opens on the axis of rotation D to the fixing elements 11, 12 to the articulated levers 17, 18 are pending. From this area, the hinge parts 1, 2 continue to move along the guides F1, F2, the gap between the first and the second fitting element 1, 2 no longer increases, but remains constant, since the fixing elements 11, 12 no longer can move on.

The Fig. 9 shows a further intermediate region between the closed position S and open position O of the hinge 100. The energy storage 80, 81 are increasingly tense, the guide elements 21, 22 proceed along their guides F1, F2.

The Fig. 10 shows how the fixing elements 11, 12 are already in contact with the articulated levers 17, 18 and a further opening in the open position of the fitting parts 1, 2 has been realized via the guides F1, F2. Fig. 10 shows the hinge 100 in the open position O. It would be possible to exceed the door hinge 100 even further, as there is still enough way along the guides F1, F2 available. By the length and execution of the guide F1, F2, the maximum travel and thus the maximum opening angle of the door hinge 100 could be defined.

The Fig. 11 shows an embodiment of the energy storage 80, 81 designed as a tension spring. At one end of the force accumulator 80, 81 is the receptacle AF for engaging in the guide elements 21, 22. At the other end is the receptacle for engagement or attachment of the force accumulator 80, 81 on the locking element 13. The energy storage 80, 81 points an extension V on which - as in the Fig. 1 visible - in guides along the cover 14, 15 is guided. These guides are used to safely accommodate the energy storage 80, 81 and also intended to prevent unwanted unhooking of the energy storage 80, 81.
