ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a hinge.
A hinge is described in EP-OS 791 713. As an adjustment device of the hinge is provided an eccentric case that is rotatably supported in a hinge wing, which guides a hinge bolt forming the axis of rotation of the hinge. The eccentric case is arrestable in any desired rotational position with respect to the hinge wing. By rotating the eccentric case one hinge wing can be adjusted relative to the other hinge wing transversely to the axis of rotation of the hinge.
Such an adjustment device is constructionally relatively expensive since the eccentric case, on the one hand, is rotatably supported in the hinge wing free of play and since, on the other hand, it must serve as play-free support for the hinge bolt. Moreover, actuation of the eccentric case is not simple since it must be rotated in the direction of the axis of rotation of the hinge, which, after installation, is often cumbersome or even entirely impossible.
SUMMARY OF THE INVENTION
An object of the invention is to avoid these disadvantages while creating a hinge of the above cited type whose hinge wings can be adjusted readily and conveniently transversely to the axis of rotation of the hinge even after installation of the hinge. A further object of the invention is to provide a hinge which is simple to produce and cost-effective.
These objects are met through the features of the invention.
While a hinge with a pivot pin directed transversely to the axis of rotation of the hinge is disclosed in EP-OS 0 810 341, the pin is not eccentric and is also not rotatable relative to a hinge wing or to a hinge holder associated with the hinge wing. The pin is also not provided as an adjustment device, but rather as a structure for hindering break-ins while received within a receiving bore in the other hinge holder.
The adjusting pin of the present invention makes possible adjusting the hinge wings transversely to the axis of rotation of the hinge by rotating the adjusting pin about its axis, whereby a lateral displacement of the two hinge wings is brought about. Since the adjusting pin is disposed on the front face of the hinge wing it is also readily accessible after installation. The adjusting pin is producible without especially narrow fabrication and bearing tolerances.
The invention provides further that the adjusting pin is provided between its two pin ends with an annular flange, and that this flange in the installed state is nondisplaceably supported in a bearing depression within a receiving bore of the hinge wing. Consequently, the rotatable adjusting pin is also nondisplaceable in the installed state such that it cannot fall out of the hinge arrangement.
It is herein of advantage if the receiving bore for the adjusting pin is an elongated bore whose major axis is disposed parallel to the axis of the rotation of the hinge. The pin end supported therein can thus move freely in this elongated receiving bore when the adjusting pin is rotated.
A further embodiment of the invention provides that the pin end supported in the elongated receiving bore projects from this receiving bore and is provided with a hexagonal recess or the like for the placement of a turning tool. This allows extremely easy actuation of the adjusting pin.
The adjusting pin according to the invention can also be used as a device hindering break-ins if the pin end supported in the elongated receiving bore projects through a penetration bore of the other hinge wing when the hinge is folded together and, in the installed state, projects into a receiving bore of a hinge holder associated with the other hinge wing. It is herein useful if both the penetration bore and the receiving bore have a diameter approximately equal to the length of the elongated receiving bore along its major axis.
In order to facilitate the adjustment of the hinge wing by virtue of the adjusting pin, the invention provides that the adjusting pin is disposed centrally in the hinge wing when viewed in the direction of the axis of rotation of the hinge.
It is herein of advantage if the hinge wing is provided with elongated bores for receiving fastening screws, whose major axes are directed transversely to the axis of rotation of the hinge.
The adjusting pin according to the invention can also be used with hinges whose hinge wings are adjustable relative to one another in the direction of the axis of rotation of the hinge, wherein an adjustment element intended for this purpose usefully acts upon the hinge wing not provided with the adjusting pin.
