ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to a running mechanism assembly for a sliding door, including a profile element with a hollow space on the upper edge of the sliding door and an upwardly opening guide groove for accommodating a running mechanism, which is constructed and adapted for engaging in a guide rail lying above it on a cabinet or on a ceiling and for guiding the sliding door suspended on running rollers.
The running mechanisms which carry a sliding door and are guided in a rail arranged above the sliding door are usually screwed firmly on the upper edge of the sliding door and, in case the latter is closed off above with a profile, the running mechanism is inserted into the profile at the end and then held fast by a locking device. With sliding doors which are surrounded by an enclosing frame, the running mechanism cannot, for aesthetic reasons, be screwed on above or be inserted through an opening laterally penetrating the frame in the profile closing off the upper edge.
SUMMARY OF THE INVENTION
An object of the present invention is to create a running mechanism assembly in which insertion of the running carriage is possible without a lateral end penetration of the frame profile surrounding the sliding door.
This objective is accomplished by a running mechanism assembly wherein a recess is provided in the profile element so as to partially expose the guide groove and the hollow space, which recess allows the insertion and fastening of the running mechanism horizontally from behind or from above into the guide groove.
Owing to the recess exposing the guide groove on the back side of the sliding door or on its upper edge, the running mechanism can be introduced, without the use of tools, perpendicular to the longitudinal extension of the guide groove into the latter and locked therein by longitudinal displacement. No further parts are necessary for locking the running mechanism. The recess is not visible from the outside of the cabinet, and therefore requires no subsequent covering. The running mechanism can be removed from the profile frame of the sliding door at any time for working on the sliding door or when changing it. The running mechanism as well as the recess in the profile element on the sliding door can be economically manufactured.
