BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to a suspension system for sliding doors with a height and inclination adjusting mechanism.


BACKGROUND OF THE INVENTION

Suspension systems for sliding doors with an adjusting mechanism are indeed known. However, they are complicated, particularly in the case of uneven floors.
In these known systems, the adjustment of the height of the door was regulated by means of a guide, which was fastened either on the door frame or on the upper edge of the door.
Thus one had to unhook the door for each adjustment, adjust the door appropriately, and again suspend the door in order to see whether the desired result had been achieved. This operation did not enable simultaneous adjustment of the inclination of the door relative to the floor.


SUMMARY OF THE INVENTION

The described invention has the goal to eliminate all of these disadvantages since the invention makes it possible to regulate the elevational adjustment of the door without unhooking same. In addition this mechanism has the possibility to simultaneously regulate the inclination of the door with respect to the floor in such a manner that an exact parallelism between door and floor is guaranteed independent of the degree of unevenness of the floor.
The system consists of a mechanism support, two screws with two corresponding cylinders and a spring to limit the movement of the screws.
This suspension system for sliding doors is fastened between the door frame and the upper edge of the door, and enables the adjustment of the height and and inclination of the door relative to the floor.


BRIEF DESCRIPTION OF THE DRAWINGS

The type of use of this invention will be explained in the following listed drawings, in which:
FIG. 1 is a longitudinal cross-sectional view of the front part of the suspension mechanism, in the lowermost operating position.
FIG. 2 is a longitudinal cross-sectional view of the front part of the suspension mechanism, in its uppermost operating position.
FIG. 3 is a longitudinal cross-sectional view of the rear part of the suspension mechanism, in its lowermost operating position.
FIG. 4 is a longitudinal cross-sectional view of the rear part of the suspension mechanism, in its uppermost operating position.
FIG. 5 is a cross-sectional view of the suspension mechanism, in its lowermost operating position.
FIG. 6 is a cross-sectional view of the suspension mechanism, in its uppermost operating position.


DETAILED DESCRIPTION

The drawings illustrate a suspension mechanism for sliding doors with a height and inclination adjusting mechanism basically consisting of a mechanism support (1), a short screw (2), a long screw (2a), two cylinders (3, 3a), which have each a taphole perpendicular with respect to its longitudinal axis, a spring steel plate (4), which limits the movement of the screws (2, 2a), a clamping metal plate (5) of the mechanism support (1) in the section or track (6) of the door, a pin (7), which centers the mechanism support (1) in the section (6) of the door, a centering pin screw (8) which fixes the pin (7), a screw (9) which connects the mechanism support (1) to the wheel support (10).
Based on this invention the mechanism support (1) fits into the section (6) of the door, which is U-shaped.
The two open ends (11, 11a) of the section (6) form at the end two corners (12, 12a), into which extends the mechanism support (1).
The section (6) of the door can either be an independent part, which is fastened on the upper edge of the door, or the upper part of the door is manufactured such that the door already houses this section.
Blocking pins (14) are mounted on the door, namely where the two ends of the mechanism support (1) end, which blocking pins prevent the mechanism support (1) from running out of the track (6) of the door.
In order to permit the door to move parallel with respect to the door frame, wheels (16, 16a) are mounted, which roll on the section (15) of the door frame.
These wheels (16, 16a) are connected to one another by the wheel support (10).
Each wheel (16, 16a) is
