Hinge for a window, a door or the like.

The innovation concerns a hinge for a window, a door or the like, with a hinge bracket whose base plate to be screwed to the frame has two spaced-apart bearing eyes has, between which a hinge sleeve is rotatably mounted on an axle bolt and the base plate on the Bearing eyes extends out and the de »hinge bracket and the hinge sleeve connecting axle bolts at one end with a Securing element is provided against unwanted axial displacement of the axle bolt, which is against a base plate extension is determinable.

Such a hinge is known (DT-GM 73 16 796). To secure the axle bolt at its lower end there is a Riveted elbow that is screwed to the window frame with a screw. Also in the area between the bearing eyes arranged a snap ring which engages around the axle bolt. This makes it easier to insert when installing on the window of the axle bolt in the hinge difficult, because the snap ring expanded by the axle bolt is pressed due to it large spring force strongly against the üiafang of the axle bolt, whereby when inserting the axle bolt, an increased frictional resistance has to be overcome. Another disadvantage is that the axle bolt can only be secured by the angle piece with the aid of a screwdriver to tighten the screw can be set. This fuse leadthrough is complex and, in the screwed-on state, is also the angle piece visible, which spoils the appearance of the hinge.

Accordingly, the object of the innovation is the above-described Avoid disadvantages and a hinge of the type described above To create embodiment, the securing element is arranged in a concealed manner, simplifying the assembly of the Axle bolt and the operation of the securing element.

This object is achieved according to the invention in that the securing element is provided with a nose and the base plate extension with a groove for pivoting the nose and that on the Hinge bracket a cover cap that overlaps the securing element is clamped.

This has the advantage that the axle bolt without assistance tool can be quickly and easily secured by hand by the fitter against axial displacement. When inserting the nose is in a pivoting position facing away from the hinge bracket, which is due to the protrusion of the fitter Nose is easily adjustable. After inserting the axle bolt, the nose is pivoted axially by a simple rotation, see above that it engages in the groove of the base plate extension and held between the groove walls that overlap on both sides is. In this position the axle bolt is against axial displacement and secured sliding out downwards, whereby a snap ring clampingly encompassing the axle pin, as in the known hinge is used, is not required, so that the axle bolt can be easily inserted into the hinge. So that the nose does not automatically swing out of the groove a cover cap is pushed over the securing element and clipped onto the hinge bracket. The free legs lock the cover cap off the side openings of the groove and secure the nose in the groove against pivoting out, the securing element advantageously being shielded by the cover cap. Through

the clip fastening has the further advantage that the axle bolt is secured in the event of any subsequent work on the window can easily be removed by hand by pulling the cover cap off the hinge bracket in order to swivel out the groove to release the nose.

For securing the axle bolt, it is advantageous to use the securing element to be provided with a sleeve, the length of which corresponds to the distance between the bearing eye and groove, that the sleeve has a locking cam has, which is arranged in an annular groove of the axle bolt, and dal? the safety element rotatable on the axle bolt is stored. As a result of the engagement of the locking cam in the annular groove, the securing element is held captive on the axle bolt. When inserting the axle bolt, the end face of the sleeve hits the bearing eye. The nose is in this end position in a common plane with the groove, so that the nose can be safely swiveled in without time-consuming pushing back and forth of the axle bolt is required for precise position adjustment. Due to the rotatable mounting on the axle bolt the securing element can be swiveled into the groove quickly and without jamming without great effort.

It is advantageous that the outer contour of the nose is the same as the outer contour of the bearing eyes and the cap is the bearing eye

and. encompasses the nose in a form-fitting manner. This form-fitting grip around the bearing eye and securing element are completely covered Arranged under the cover cap, so that the hinge looks flawless without any annoying projections or the like. Given is. The lug that matches the outer contour of the bearing eye rests against the inner surface of the cap, whereby the Nose is held immovable in its locking position in the groove.

To enable the hinge to be used on the right or left, it is advantageous to that each base plate extension is provided with a groove. This makes it possible to use the axle bolts on the right and to insert and secure the hinges hinged on the left from only one side. This is necessary, for example, if the Hinge designed as a scissor bearing is posted on top of a tilt and turn window and the distance to the overlying The lintel is smaller than the length of the axle bolt. The axle bolt is inserted from below and on the lower one Base plate extension secured.

According to another preferred embodiment, it is advantageous that the securing element is provided on its side facing away from the nose with an annular flange and the radius of the annular flange is smaller than the distance between the end face of the outer groove end wall, but greater than the distance between the end face of the

7713654 08/11/77

other groove wall close to the bearing eye. It is possible to design the securing element as a flat washer that is rotatably riveted, for example, to the end of the axle bolt. Since the outer groove wall is shorter, the ring flange can be pushed past it when the axle bolt is inserted until it comes to rest against the other longer groove wall, whereby the insertion end position is reached in which the Nee can be swiveled into the groove .

Further advantages and details of the innovation can be found in the drawing, the preferred embodiments in a schematic Illustration shows as an example. They represent:
