- German utility model application
DE202004003289 (U1 ) discloses a vertical adjustment system for sliding door in building provided with a horizontal screw forcing nut with sloping bottom surface against sloping ramp. A carriage at the top of a sliding door has a fastening flange fixed to the door at two sides of a main housing placed in the socket shaped in the door, and has an adjustment system. A screw engages a square nut which have fits inside an adjustment block. A sloping bottom edge of the nut rides up a sloping ramp in the adjustment block to give the vertical adjustment. The screw extends through a bore in a housing and has a hexagonal socket to accommodate an Allen (hexagonal) key. In none of the above mentioned mechanisms a problem of easy adjustment of the door wings hanged on the sliding devices or trolleys is solved acceptably. In particular a solution proposed inDE202004003289 cannot be used for heavy plates because of necessity to use very big force to overcome friction between oblique adjacent surfaces of a nut pressing on a "ramp" of an "adjustment block". Also possible range of vertical movement is very limited, because a slope of oblique surfaces cannot be too high for the same reason. - Another German patent application
DE2546384 (A1 ) discloses a suspension system for sliding doors or partition walls which has a cylindrical self adjusting mounting on door panel. The mounting element is connected by an adjustable block to a connecting strap between the door and roller element and is readily adjusted without using an additional clamp. The mounting fitting has within its cylindrical shape a sliding block between two parallel guides. This block is connected to the suspension assembly overhead. The guides can be formed by a rectangular opening within the cylindrical mounting fitting. The block is guided in this opening without play and is moved vertically by an adjusting screw. German utility model applicationDE8334024 (U1 ) describes the invention which relates to a sliding door with a device for suspending the support of height-adjustable suspension elements arranged on the upper door edge. It is connected to a chassis running on profile rails, each suspension element projecting into a recess arranged in the side face of the sliding door and being connected there in a force-locking manner to the sliding door and being fixable in its height adjustment. -
FR1548070 A - According to the invention, an adjustment device for a sliding door trolley comprises the features of
claim 1. The screw is movable along vertical axis of the slider and works with the nut immovably mounted in the slider. - The term "vertical axis" is understood here as a straight line made by an intersection of a plane of symmetry of the housing, and a plane parallel to the front and/or rear plane of the housing but passing through its middle. It shall be obvious to a person skilled in the art that invented device can be mounted in any position, so that "vertical axis" has a conventional meaning, and shall not be necessarily understood as vertical if referred to the gravity field. In particular, vertical axis of claimed device can be positioned horizontally if the device is turned by a right angle. However, in most applications of the adjustment device for top hung and bottom rolling systems, its vertical axis is positioned vertically.

- In one embodiment the nut is hexagonal and is immobilized in a nut socket shaped in the slider, preferably in its top convex (cylindrical) wall. In the latter case the top wall of the slider has the same curvature as the cylindrical wall of the housing.
- Alternatively, the nut is rectangular and is immobilized between the nut socket protrusions shaped in the slider. One of the nut rectangle sides is leaning against the bottom of the socket shaped in the base plate, e.g. the door wing, and then its rotation is blocked.
- The slider has protruding side elements guided in vertical guides shaped inside the housing. Alternatively, the nut socket protrusions of the slider are guided in a rectangular hole shaped in the front wall of the housing.
- The head of the screw abuts a thickening and/or a washer, e.g. a spring washer at the bottom of the slider.

figs. 16 to 19 . The main plate of the trolley is immobilized on the base plate (6) with the screws inserted into oblong holes (fig. 17 , left) in the trolley main plate, allowing for vertical regulation of the trolley coupled to the adjustable device. With loosened screws of the trolley the regulating screw (3) is adjusted with use of a flat wrench, and finally the screws of the trolley are tightened. The screw (3) has a hexagonal head (9) fitting a flat wrench (10), as shown infig. 15 . The trolley main plate blocks the adjustable device inside the cylindrical recess (5), cf.figs. 16 to 19 . The slider (2) has also the openings (8) to receive the protrusions shaped in the trolley main plate. - The nut (4) is hexagonal and is immobilized in a nut socket (11) shaped in the slider (2), cf.
fig. 5 . However, in the embodiment made of the steel sheet the nut (4) is rectangular and is immobilized between the nut socket protrusions (12) drawn in the slider (2). The nut (4) can be spot-welded to the nut socket protrusions (12). - The slider (2) has protruding side elements (13) guided in vertical guides (14) shaped inside the housing (1). But again, in the embodiment made of the steel sheet the nut socket protrusions (12) of the slider (2) are guided in a rectangular hole (15) shaped in the front wall (16) of the housing (1).
- The top wall (17) of the slider (2) has the same curvature as the cylindrical wall (18) of the housing (1). The head (9) of the regulating screw (3) abuts a thickening and/or a washer (19), preferably a spring washer.
- The housing (1) has the protruding bottom parts (20) immobilizing the housing (1) in the cylindrical recess (5) machined in the base plate (6). The cylindrical wall (18) of the housing (1) has the ribs (21) or knurling immobilizing the housing (1) in the cylindrical recess (5) in the base plate (6).
