Detailed Description

In the following description of the drawings, terms such as top, bottom, left, right, front, rear, etc. relate only to illustrations and positions chosen by way of example in the respective drawings of an adapter, a retaining element, a door or window handle, a collet, a base body, a clamping element, etc. These terms should not be construed as limiting, i.e., these references may vary due to various operating positions or mirror symmetric designs, etc.

In fig. 1, reference numeral 1 denotes a part of a door or window frame, wherein a door or window handle 2 having a handle neck 21 is fixed by means of a holding element 5, which handle neck 21 has a gripping portion 22.

In this case, the holding element 5 is preferably designed as in DE 202015101329U 1 of the applicant, the functional description of which is expressly referred to here.

As can also be gathered from fig. 1, the door or window frame 1 comprises a receptacle opening 8 for receiving the adapter 3.

A first embodiment variant of such an adapter is shown in fig. 4. A second embodiment variant of such an adapter is shown in fig. 5a and 5 b. Both variants have the following features: the adapter 3 comprises a cylindrical jacket 31 and a base 36 extending from the inner surface of the jacket.

Other shapes of the jacket design are also conceivable, for example polygonal. In this case the base is provided with a polygonal receptacle 34 and at least two holes 33.

In this case, the holes 33 are intended to receive screws 9 for fixing the adapter 3 to the window or door frame 1. The polygonal receptacle 34 arranged centrally in this case serves to guide through a polygon 4 formed as a quadrangular bar, which extends from a cavity inside the handle neck 22 through the retaining element 5 into the gear arrangement or locking unit 11 in the window or door frame 1.

A cover disc 6 is provided to cover the holding element 5 from the visible side of the door or window frame 1. The door or window handle 2 is fastened to the holding element 5 by means of a fastening screw 7, which fastening screw 7 extends through a receptacle 23 in the side of the handle neck 2 into a receptacle 53 in a receptacle body 52 of the holding element 5, in which receptacle body 52 a polygon 4 is accommodated.

As shown in fig. 1, 4, 5a and 5b, the collet 31 comprises two holes 32 for accommodating clamping elements 54, the clamping elements 54 being radially movable out of the base body 51 of the holding element 5 and being in particular pivotably held on the base body 51.

It is also conceivable to provide only one such clamping element 54 on the holding element 5 and thus only one such hole 32 in the jacket 31 of the adapter 3.

The hole 32 is here formed as a through hole. It is also conceivable to keep the jacket outer surface of the jacket 31 closed and thus to form the aperture 32 as a pocket aperture.

In this case, the holes 32 are preferably formed on the opposite jacket surface inner sides of the jacket 31.

In order to rotationally fix the holding element 5 relative to the adapter 3, two recesses 35 are preferably introduced in the jacket inner surface of the jacket 31, said two recesses 35 being intended to receive projections projecting radially outwards from the base body 51 of the holding element 5.

As further shown in fig. 4, the base 36 of this embodiment variant of the adapter 3 is formed in a star shape. In this case, the arms in which the holes 33 are arranged extend radially from the polygonal receptacle 34 towards the jacket 31.

In addition to the four-armed star configuration of the base 36 shown here, it is also conceivable to provide, for example, only two, three or more than four such arms.

In the embodiment variant shown in fig. 5a and 5b, the base 36 is formed as a circular plate with a corresponding hole 33 and a centrally arranged polygonal receptacle 34. The pin 37 is preferably arranged (in particular formed) extending perpendicularly with respect to the plane of the base on the rear side of the base 36 facing away from the holding element 5.

The adapter 3 is preferably designed as an injection-molded part.

To mount the door handle or window sash 2 on the door or window sash 1, the adapter 3 is first inserted into the receptacle opening 8 of the door or window sash 1 and the adapter 3 is fixed by means of the screw 9.

With an additional twist-lock of the variant of embodiment of the adapter 3 shown in fig. 4, the receptacle opening 8 comprises, with respect to the door leaf or sash 1, a corrugated contact surface 82, which corrugated contact surface 82 is formed according to the star-shaped structure of the base 36 of the adapter, so that the bottom 36 is fixed in the receptacle opening 8 in a form-fitting manner in a direction perpendicular to the longitudinal extension of the polygon 4, wherein the polygon 4 pivots when the door handle 2 is actuated.

For an additional twist-lock of the embodiment variant of the adapter 3 shown in fig. 5a and 5b with respect to the door leaf or window sash 1, in which the polygon 4 pivots when the door handle 2 is actuated, a corresponding recess for receiving the pin 37 is provided in the receptacle opening 8, so that the base 36 is also fixed in the receptacle opening 8 in a form-fitting manner in a direction perpendicular to the longitudinal extension of the polygon 4.

Subsequently, as shown in fig. 2 and 3, the polygon 4 is inserted into the door or window frame 1 through the polygon receptacle 34 of the adapter and upward into the locking unit 10.

In order to prevent the polygon 4 from advancing and extending beyond the target position, according to the preferred embodiment variant shown in fig. 6 to 8, a protrusion 44 for limiting the insertion depth of the polygon is formed on the outer surface of the polygon.

In this case, the projections can be introduced, for example, by deformation of the outer edge of the body 41 of the polygon 4, in particular in the form of material displacement, the cross section of the body of the polygon preferably being formed as a square.

In this case, the projection 44 is pressed against the housing wall of the lock unit 11 toward the door handle or window handle 2 in the mounted state of the door handle or window handle 2, and the polygon 4 is inserted into the lock unit 11.

In this case, the polygon 4 is preferably provided as a hollow profile with a longitudinal bore 45 with an internal thread, into which longitudinal bore 45 the locking screw 43 can be inserted. A longitudinal groove 42 extending in the longitudinal extension direction of the polygon is preferably introduced on the end of the polygon 4 inserted into the locking unit 11.

The end of the polygon 4 provided with the longitudinal slot 42 is slightly flared by inserting the screw 43 into the cavity 45 of the polygon 4, so that the polygon 4 is held in the locking unit 11 in a clamping manner.

Subsequently, the holding member 5 is placed on the polygon 4.

The cover disk 6 is then pushed onto the handle neck 22 of the door or window handle 2, and finally the door or window handle 2 is placed by means of the handle neck 22 on the receptacle body 52 and the door or window handle 2 is fixed using the locking screw 7, the receptacle body 52 being mounted pivotably in the base body 51 of the holding element 5.
