Window Unit Having Decorative Strip Mounted Thereon
In the window unit composed of a window pane and frame, the frame has two profiled sections. The first profiled section serves for connecting to the window pane and generally extends along the entire window pane edge and bears against it at an edge region or at two or three edge regions. The second profiled section serves for connecting to a decorative strip and therefore generally extends over only a predefined longitudinal section of the frame. The second profiled section of the frame generally has a plurality of longitudinal sections with a bearing face for the decorative strip. In addition, the second profiled section generally has a plurality of longitudinal sections each with a continuous cutout, located in the region of the horizontal projection of the decorative strip, for a securing strip. On the underside of the decorative strip there is a longitudinally extending cutout with a cross-sectional constriction. Each securing strip has a cross-sectional widened portion which is matched to the cross-sectional constriction on the decorative strip in order to form a clipping effect. Each securing strip has, on the side facing away from the decorative strip, a securing plate whose horizontal projection extends at least in certain regions beyond the horizontal projection of the cutout in the second profiled section of the frame. The securing plates of all the securing strips which are present are expediently connected to one another so that the securing strips can together be plugged from below through the cutouts in the second profiled section of the frame in order to be able to clip the decorative strip onto it from above.

In automobile window units composed of a window pane and frame, a decorative strip is sometimes mounted along a predefined longitudinal section of the frame. For this purpose, securing elements for the decorative strip are arranged in said longitudinal section of the frame. In a known embodiment (DE 198 18 153 A1), base bodies made of a material with a relatively high strength are integrated along the respective longitudinal section of the frame for the securing elements. During the manufacture of the frame they are inserted into the injection molding mold and positioned therein by means of positioning elements. After the window unit has been removed from the mold, protruding parts of the positioning elements are removed. Securing clamps made of metal are fitted onto these base bodies later, said securing clamps engaging on the one hand in grooves in the base bodies and on the other hand have latching wings onto which the decorative strip is clipped.
This method of securing a decorative strip is used in window units in which the frame projects into the face region of the window pane and therefore the securing means for the decorative strip can be accommodated in this face region of the frame.
In the case of window units in which the horizontal projection face of the frame is located for the most part outside the window pane, a decorative strip cannot be anchored by means of an embedded base body.
The invention is based on the object of providing a means for securing decorative strips which is additionally also easy to mount even for such window units.
This object is achieved by means of a window unit having the features specified in claim 1.
A first part of a securing means for the decorative strip is provided by virtue of the fact that the window unit has, in addition to the first profiled section serving for connecting to the window pane, a second profiled section in whose horizontal projection region the frame is provided with at least one bearing face for the decorative strip and with at least one continuous cutout. A second part of the securing means is provided by virtue of the fact that on the underside of the decorative strip there is at least one longitudinal section which has a cutout with a cross-sectional constriction and by virtue of the fact that there is a securing strip with a cross-sectional widened portion.
A third part of the securing means is provided by virtue of the fact that on the securing strip there is a stop plate which partly projects beyond the cutout on the frame. All of the parts of the securing means together permit the securing strip which engages through the cutout to be clipped onto the decorative strip which is positioned on the bearing face of the frame and to be secured to the frame by means of the stop plate.
By virtue of an embodiment of the window unit as claimed in claim 2, the cross-sectional widened portion of the securing strip becomes more elastic, which facilitates the clipping onto the decorative strip.
By virtue of an embodiment of the window unit as claimed in claim 3, a plurality of securing means for the decorative strip are provided with which even relatively long decorative strips can be securely fixed.
In one refinement of the window unit as claimed in claim 4, when the cutout is open the securing strip can be fitted laterally onto the frame and pulled out, whereas when the cutout is closed the hold is better.
In one refinement of the window unit as claimed in claim 5, the securing strips form one structural unit so that they can be fitted together onto the frame and removed from it together.
With one refinement of the window unit as claimed in claim 6, the decorative strip and its securing means can be positioned even better and fixed better in the correct relative position.
In the text which follows, the invention will be explained in more detail with reference to an exemplary embodiment which is illustrated in the drawings, in which:
As is apparent from the individual illustration in
The first profiled section 21 serves for connecting the frame 12 to the window pane 11. Accordingly, the profiled section 21 extends along the entire edge of the window pane 11. The profiled section 21 is integrally formed onto three sides of the edge region of the window pane 11. Instead of the illustrated embodiment, the profiled section 21 can also bear against just two or even just one edge region of the window pane and be connected to it.
Depending on the conditions of the bodywork, the profiled section 21 can have, in other sections of the frame 11, an entirely different contour line from that illustrated.
In a predefined circumferential section of the window unit 10 and therefore in a predefined longitudinal section of the frame 12, there is, in addition to the first profiled section 21, a second profiled section 22 which serves for connecting to a decorative strip 23. This longitudinal section of the frame 12 is at least approximately in the shape of an elongated strip (
Depending on the length of the decorative strip 23, the frame 12 has, in the region of its second profiled section 22, two or more longitudinal sections 24 which have a bearing face 25 for the decorative strip 23 (
As is apparent in particular from
As is indicated in
This clipping effect is assisted by the fact that on the securing strip 28 one 36 of the profiled sections for the cross-sectional widened portion is arranged on a rib 37 which is oriented at least approximately at right angles to the rest of the securing strip 28.
