BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention concerns a device for joining a sliding element, such as a glass, metal or wooden panel, with a guide device.
DISCUSSION OF BACKGROUND INFORMATION
To close room openings, sliding doors are often used that are suspended from a carriage that is guided on a track. For this purpose, a device is provided that is attached to the sliding door and connected to the carriage via a connecting bolt. From EP 0 733 766 A2, such a device is known that consists of a mounting piece that is screwed to a sliding wooden door and is intended for the accommodation of a connecting bolt that is screwed into the carriage. The head of the connecting bolt, which is mounted to rotate in the opened mounting piece, can be fixed in place by means of a safety cover, by which the mounting piece is closed. By opening the safety cover, the connecting bolt of the mounting piece (and the sliding door) can be loosened or tightened, so that the height of the sliding door can be adjusted.
For sliding glass elements which are suspended from a carriage guided on a track, generally, two mounting pieces are required that enclose a glass element and are screwed to one another in such a way that at least one bolt equipped with a thread is guided through an opening in the glass element, whereby said element is held by positive attachment to the bolt. By screwing together the two mounting pieces, which are drawn against the glass element located between them, a frictional attachment is generally also produced. Between the mounting pieces, for example, in a U-shaped cutout in the glass element, a screw that can be connected with a carriage is mounted to rotate, by means of which the height of the glass element can be adjusted. In order to lock the connecting bolt in position, a lock nut is planned which is provided above the mounting pieces and thus above the glass element. In the event that a lock nut is to be provided at the location shown, a relatively large distance must be selected between the track and the glass element and the mounting pieces. Moreover, the protrusion of fasteners is also undesirable for aesthetic reasons or for safety reasons.
In principle, a safety cover could be provided, by which means the connecting bolt may be locked, as in the device in EP 0 733 766 A2, which is not intended for glass elements. However, doing so would result in increased expense in the manufacture and installation of the device.
SUMMARY OF THE INVENTION
Therefore, the task that forms the basis of the present invention is to create a device that can be manufactured, installed, and adjusted at low cost, by means of which a sliding element, especially a glass element, can be joined via an adjustable and lockable connecting bolt to a carriage that is guided on a track.
This task is achieved through the present invention.
In accordance with the invention, the device--which includes two mounting pieces, preferably cast, a connecting bolt, several assembly screws, and, if necessary, two covers--can be manufactured at low cost. The connecting bolt is kept between the two mounting pieces and locked by preferably two screws that are provided between the mounting pieces and that need only be loosened a few turns for the adjustment of the connecting bolt. The space between the glass element or the mounting pieces and the guide track can thus amount to merely a few millimeters so that no trim piece is required. In addition, the required assembly screws and locking screws are preferably only accessible from one side of the device in accordance with the invention so that the other side of the device in accordance with the invention, advantageously facing outward, offers no access for (undesired) manipulations.
