Description

Title: Door hinge, especially shower door hinge

The invention relates to a door hinge, in particular a shower door hinge, with a fastened to a frame construction or masonry strap portion, having a door leaf fastened to a wing hinge part which is pivotable relative to the fixed hinge part about a hinge axis between a closed position and an open position for the door, and with a self-closing device for the door hinge or the door leaf.

A door hinge with self-closing device is known for example from DE 102 04 326 Al, said hinged hinge is intended for insect protection doors and two hinge parts, each provided with a return sleeve, each having a sloping ramp surface to the restoring torque upon deflection of the door leaf to produce from a closed position.

In the state of the art, it is also known to provide a hydraulic or spring-loaded arm as a self-closing device, wherein during the opening movement the restoring force is stored in the spring or in the hydraulic medium and then released again for the automatic closing of the door. Such a separate, the self-closing function acquiring component is unsightly especially in shower doors and doors in glass constructions and also maintenance-intensive and susceptible to wear. The object of the invention is to provide a door hinge with self-closing device, which allows a safe closing of the door, is wear-prone and at the same time leaves a designer a lot of leeway for the shaping of the door hinge.

This object is achieved in that the self-closing means comprises a fixed band part associated with the first magnet and a the Flügelbandteil associated second magnet whose magnetic attraction and / or repulsive force causes the closing movement of the door hinge or the door leaf. According to the invention is therefore provided that each of the two hinge parts of the door hinge is associated with a magnet, which, depending on the pivot position of the two hinge parts to each other, either attract or repel the magnets, each of these magnetic force preferably causes only the closing movement of the hinge parts of the door hinge. The magnets are not subject to wear and are completely maintenance-free.

Since according to the invention in each case one of the band parts is associated with a magnet, preferably the fixed band part and / or the leaf band part consist of a non-ferrous metal such as in particular zinc or brass. Alternatively, the fixed-band part and / or the wing hinge part could also be made of plastic. The main advantages of these materials are that the magnetic fields of the two magnets are not weakened by the material of the band parts and also no undesirable interactions between the material of the band parts and the magnets occur. Further preferably, both the first magnet and the second magnet consist of permanent magnets (permanent magnets). As a material for the permanent magnets is in particular a material from the group of rare earths in question. Due to their high magnetic force at comparatively low volume, the magnets consist in particular of neodymium magnets with a suitable alloy of neodymium, iron and boron. Both magnets may be formed in particular strip-shaped or cuboid.

It is particularly advantageous if the first magnet and the second magnet are positioned in their band parts such that the magnetic field of the first magnet and the magnetic field of the second magnet in the closed position lie substantially in a row, so that in the closed position due to the same orientation the polarities of the magnets the maximum attraction between the two magnets is effective. Conveniently, an air gap is formed in the closed position between the first magnet and the second magnet, on the one hand to facilitate the movement of the door from the closed position into the open position and also exert a closing pressure or contact pressure on the door in the closed position. By these measures, the door leaf can be biased against a door frame, which at the same time forms a stop for the door leaf, in order, e.g. to achieve a sealing effect between the door leaf and the door frame. In this case, it is particularly advantageous if the air gap is uneven and in particular increases with increasing distance from the hinge axis.

The magnets may have different dimensions, in which case the larger magnet is preferably associated with the fixed band part. The pivot angle of the band parts to each other is preferably limited to less than 180 °. A particularly compact design of the door hinge can be achieved if one of the magnets, in particular the first magnet associated with the fixed band part, is arranged on or in the region of the hinge axis. In this case, it is particularly advantageous if, then, the hinge axis is eccentric to the center or one of the telach.se this magnet is aligned. Due to the eccentric arrangement of the pivot axis can be achieved that the magnet is moved in the other band part with a small distance to the other magnet during the pivoting movement.

A particularly simple construction for a door hinge results when one of the hinge parts has a hinge web which is positioned in the assembled state between two bearing webs on the other hinge part, wherein the hinge web is provided with a receiving recess for one of the magnets. Further preferably, then, the wing hinge part having a releasably connectable to the door mounting part, on the front side of the bearing webs are arranged, wherein in the end face between the two bearing webs a receiving recess is formed for the second magnet. In this embodiment, the Schwenkaσhse the door hinge preferably consist of two pivot pins, which pass through the bearing webs and engage in recesses in the hinge web. The pivots may consist of screws with pivot pins at the ends. For a continuous use of the door hinge is also advantageous if slide bushes are arranged in the recesses of the hinge web, in which the pivot pin enclose sliding.

Further advantages and embodiments of the invention will become apparent from the following description of an embodiment schematically shown in the drawing. In the drawing show:

Figure 1 is a perspective exploded view of the main components of the door hinge according to the invention.

FIG. 2 shows a plan view of a door hinge mounted on a door leaf in the closed position; FIG. Fig. 3 is a horizontal section through the door hinge of FIG. 3;

FIG. 4 shows the door hinge in a sectional view according to FIG. 3 in an intermediate pivoting division; FIG. and

5 shows the door hinge in a sectional view according to FIG. 3 in the open position.

In the figures, 50 denotes a door hinge according to the invention which can be used in particular as a shower door hinge and comprises a fixed to a masonry, a frame construction of a shower cubicle or a glass plate of a glass construction shower stall fixed hinge part 10 and attachable to a door leaf hinge part 20 , The door leaf, which may for example consist of a glass plate, is schematically indicated in FIGS. 2 to 5 and provided with reference numeral 1, while the masonry or a frame construction are not shown.

From Fig. 1 it is readily apparent that existing as a casting of non-ferrous metal such as zinc fixed belt member 10 is provided with a Festschraubleiste 11, in which two slots 12 are formed for the penetration of mounting screws. The elongated holes 12 facilitate the alignment of the fixed band portion 10 on possibly uneven masonry. The fixed band part 10 further comprises integrally a relatively solid locking web 13, the longitudinal extent between its two ends 14 is smaller than the length of the screwed screw 11 between the two transverse edges 15 between the Arretiersteg 13 and the Festschraubleiste 11 is one with a plant trough 16th provided intermediate strip 17 is formed, wherein the Festschraubleiste 11, the intermediate strip 17 and the Arresting bar 13 are formed strong enough to wear a door hinged and can support.

The leaf hinge part 20 comprises an approximately wedge-shaped in the embodiment shown fastening part 21, at the wider end face 22, two spaced-apart bearing webs 23 on the end face 22 protruding integrally formed during casting of the leaf hinge part. The free distance between the two bearing webs 23 is slightly larger than the length of the Arretiersteges 13 of the hard belt part 10, so that the Arretiersteg 13 can be accommodated between the two bearing webs 23 and there, with the formation of a hinge axis, as will be explained, with the leaf hinge part 20 can be connected. The rotational movement of the two band parts 10, 20 to each other allowing attachment of the hinge web 13 to the bearing webs 23 of the wing hinge part 20 by means of sliding bushes 2, the peg-like projections 3 and engage in accordance with provided in the end faces 14 of the Arretierstegs 13 recesses 18, and by means of fastening screws 4, which include an externally threaded head 5 and a pivot portion 6 which engages in the mounting state of the door hinge 50 in the pin projection 3 on the sliding bushes 2 such that the bearing pin 23 can move relative to the hinge web 13. The fastening screws 4 are in this case screwed into internally threaded mounting holes 24 in the bearing webs 23 of the wing hinge part 20. From Fig. 1 it is readily apparent that the holes 18 are arranged eccentrically in the Arretiersteg 13 and also the pin projections 3 are arranged on the sliding bushes 2 eccentrically to annular disks 2 A on the sliding bushes 2.

As door 1 for a shower door hinge is preferably a glass or the like. for use. Since with glass panes the fixing screws for holding the glass plate are not immediately bar can be screwed into the glass pane 1, in addition to the wing hinge part 20, a terminal block 26 is provided which by means of further not shown fastening screws under clamping the door leaf 1 forming glass between them and the fixing part 21 of the wing hinge part 20 can be screwed to this. To protect the glass pane each EPDM plates 27, 28 are arranged on the contact surfaces between the fastening part 21 and the terminal block 26 and the glass pane. When using the door hinge 50 as a shower door hinge with glass pane, the hinge-side vertical longitudinal edge 1 'of the door leaf 1 is further provided with a rubber seal 7, which in the closed position of the shower door hinge 50 partially on the masonry or the frame construction and partially on the trough 16 of the gutter 17 of the fixed band part 10 sealingly applies.

According to the invention, both the locking web 13 and the leaf hinge part 20 are now provided in the end face 22 between the two bearing webs 23 each with a receiving recess 19 or 25 (FIG. 3) for receiving two neodymium rectangular magnets 30, 40. From Fig. 3 it can be clearly seen that both receiving recesses 19, 25, the two permanent magnets 30, 40 approximately match exactly record and limit it on three sides. The two permanent magnets 30, 40 are preferably glued into the receiving recesses 19, 25 and the arranged in the hinge web 13 magnet 30 has a larger volume and thus a higher magnetic force than the permanent magnet 40th

In the illustrated embodiment, the opening of the receiving recess 19 is in the Arretiersteg 13 perpendicular to Festschraubleiste 11 of the Festbandteils 10 and the door hinge 50 has a closed position for the door 1, wherein the door 1 perpendicular to Festschraubleiste 11 and thus perpendicular to the masonry or a boundary wall of a shower cabin is aligned. For other applications, the opening of the receiving recess in the Arretiersteg could also be aligned parallel to Festschraubleiste 11, whereby the door hinge would then have a closed position in which the door is parallel to Festschraubleiste Festbandteils.

With the first permanent magnet 30 arranged in the arresting bar 13 of the fixed band part 10 and the second permanent magnet 40 fixedly arranged in the leaf band part 20, a self-closing function of the door hinge 50 in the assembled state is achieved. For explanation, reference is made in particular to Figs. 3 to 5 reference. Fig. 3 shows the closed position of the door hinge 50, Fig. 4 is an open position in which the door 1 is pivoted by 45 ° compared to the closed position, and Fig. 5 shows an open position in which the door 1 90 ° moved out of the closed position is. The self-closing function of the door hinge 50 is effected in all pivot positions of the two hinge parts 10, 20 relative to one another exclusively via the magnetic fields of the two permanent magnets 30, 40. The two permanent magnets 30, 40 are arranged in the mounting state of the door hinge 50 in the receiving recess 19 in the hinge web 13 and in the receiving recess 25 in the leaf hinge part 20 such that they are aligned in the closed position shown in FIG. 3 with their magnetic fields substantially the same and in Row lie, causing the two permanent magnets 30, 40 magnetically attract and pivot the two band parts 10, 20 in the closed position. In contrast, the two permanent magnets 30, 40 in the position shown in Fig. 5 of the door hinge part 20 to the fixed band part 10 magnetically repel, since in this 90 ° -Schwenkstellung one of the poles, for example, the north pole of the permanent magnet 40 transverse to the magnetic field of Permanent magnet 30 is located and thus opposite to the north pole of the permanent magnet 30 transversely. In the pivoting position shown in FIG. 5, therefore, the repulsive force between the permanent magnets 30, 40th to bear, from which a permanent turning or restoring moment here in a clockwise direction on the wing hinge part 20 results. In the intermediate position shown in Fig. 4, the change of the driving force for the closing movement of the magnetic repulsion force of the two permanent magnets 30, 40 takes place on the magnetic attraction of the two permanent magnets 30, 40.

FIGS. 3 to 5 further illustrate the advantage of the eccentric arrangement of the hinge axis S (FIG. 2) on the fixed-band part 10. Although the magnet 30 in the fixed-band part 10 lies in the region of the hinge axis, it is aligned eccentrically to the center of the magnet 30 , Due to the eccentricity, it is achieved that the two permanent magnets 30, 40 can be pivoted relative to one another with a comparatively small distance between the poles of the magnets. Finally, Fig. 4 also shows that in the closed position of one of the permanent magnets, here the magnet 40 is arranged at a small angle α of, for example. 3 ° obliquely relative to the other permanent magnet 30, whereby even in the closed position, a tightening force between the two permanent magnets 30, 40 remains effective, which presses the door 1 permanently in the closed position. At the same time this has the advantage that in the closed position, a small, uneven air gap between the two permanent magnets 30, 40 is present, which facilitates the opening of the door hinge 50, since no additional contact adhesion forces when opening the door hinge 50 must be overcome.

Those skilled in the art will recognize from the foregoing description numerous modifications which are intended to be within the scope of the appended claims. In the illustrated embodiment, the permanent magnets 30, 40 have different dimensions, wherein the larger permanent magnet 30 is arranged in the hinge web 13 of the fixed-band part 10. This embodiment could already meet vice versa without further ado when the hinge web on the wing hinge part and the bearing webs are formed on the hard-belt part. The hard-belt part could also be attached to glass panes of an entrance area or a shower cubicle, which lie parallel to the door leaf in the closed position of the door hinge. Such entrance areas or shower cubicles can also be designed as a "frameless" all-glass construction or glass-glass construction and comprise glass plates which are connected to each other via fittings and form the frame construction with their glass plates. It is understood that in this embodiment, then the hard-belt part has a modified Festschraubleiste with a retaining strip or the like. interacts, which pinch another glass plate between them. Instead of two parallelepiped neodymium permanent magnets, magnets made of other materials, magnets of other geometries, or several pairs of magnets could also be used. The door leaves can be made of any materials.
