Description

The invention relates to the manufacture of furniture, namely, to the construction of supports with upper guide rollers for the inner and outer doors of the sliding wardrobe system, in particular, to the running element for the inner sliding door leaf.

The design of supports with upper guide rollers for the internal and external doors of the sliding system of the sliding wardrobe includes various components and parts, the main function of which is to ensure free movement along the guides of the door leaf of various sliding wardrobes. The guides have tracks in the form of gutters that prevent the door leaf from shifting perpendicular to its plane. However, if excessive physical force is exerted during opening or closing the door leaf, the door leaf may exit the guide track. Especially in order to avoid such problems, a locking device is provided in the design of the running elements, which prevents the roller from escaping from the guide track.
