Attorney file: 1098,2 October 2001 Gate fitting

The present invention relates to a gate fitting. The gate can be any outdoor gate or one that can at least be opened to the outside and can therefore be swung over an at least partially uneven surface or an ascending or descending surface.

There are various, usually very complex, constructions that can be used to raise or lower a gate when it is pivoting. The simplest way to adapt to rising or falling terrain is to move the hinge angle away from the vertical. However, gates suspended in this way will then always close by themselves and must be kept open for passage or driving through. There is also the method of suspending a gate on a rope that is offset sideways and upwards from the pivot axis. However, this requires a high suspension point and the view of this suspension is not attractive.

The task is therefore to provide a gate fitting that can be installed inconspicuously and, in particular, overcomes small uneven surfaces effortlessly and without the need for any effort. The solution to the problem generally consists of a gate fitting made up of at least two parts, with both the upper and lower hinges being connected to the hinge via a joint whose axis is arranged transversely to the hinge axis.

The gate fitting is suitable for straight or horizontally opening fence gates, gates and doors, as well as for rising or sloping terrain. Each one is a band, normally

Usually the upper hinge is a fixed hinge that can be rotated, and the lower hinge is also a hinge that can be moved along the axis of the hinge. On sloping ground, where the gate is to be lowered, the arrangement is reversed.

Further details, features and advantages emerge from the following description of an embodiment shown in the drawing and the claims.

Show it:

Figure 1 is a view from the inside of a door leaf with the fitting arranged on the right,

Figure 2 is a schematic perspective view of the upper fitting and

Figure 3 is a schematic perspective view of the lower fitting.

A door leaf 10 is attached to the post 12 with a fitting according to the invention. On the door leaf 10 there is a fitting band 14 at the top and a fitting band 16 at the bottom. Two brackets are screwed into the post 12, a bracket 16 at the top and a bracket 18 at the bottom. An adjustable tilting safety device 19 is provided against the post 12 in both brackets 16, 18. A sleeve 22 at the bottom and a sleeve 24 at the top can be attached to the pins 20. The upper sleeve 24 is firmly connected, for example welded, to a screw bolt 26 protruding from its circumference, which extends parallel to the band 14 when mounted and forms an upper joint with the sleeve 24 around a gate pivot axis A. The lower sleeve 22 is connected in a similar way to a sliding bolt ea.30 £a&t .

in the assembled state extends parallel to the lower band 16 and forms a lower joint around the pivot axis A with the sleeve 22. The upper screw bolt 26 is adjustably screwed into a joint piece 32 which is rotatably mounted in the band 14 transversely to the upper band 14 about an axis B in the direction of the arrows shown in Figure 2. The bolt 26 is secured in an aligned position by one or two nuts 34 and washers 36.

The lower sliding bolt 30 passes through an opening 40 in a lower joint piece 38, which is mounted transversely to the lower hinge 16 about an axis C in the direction of the arrows shown in Figure 3 in the lower hinge 16. The sliding bolt 30 has a sufficiently long sliding zone in its longitudinal extension, which can move back and forth in the opening 40 in the lower joint piece, and beyond the opening 40 the sliding movement is limited by lock nuts 42. This allows the axis A to pivot through an angle α (Figure 1) and the door leaf 10 can be raised when pivoting about the axis A, which can be achieved, for example, by a curved rail 44 embedded in an uneven floor, on which a roller 46 attached to the free end of the door leaf rolls.

In the case of small unevenness, i.e. small angle α, a small or sufficient play in the opening 40 is sufficient to allow the sliding bolt 30 to follow the movement. In the case of larger unevenness, inclines or sloping ground, a longer sliding bolt 30 can be allowed an additional movement around an axis D in its root.

Claims (5)

1. To make a gate fitting for gates that can be opened over uneven surfaces, rising or falling ground, which can be installed inconspicuously and in particular overcomes smaller uneven surfaces effortlessly without the use of force, characterized by a gate fitting consisting of at least two parts, wherein both the upper and the lower gate hinge ( 14 , 16 ) are each connected to the gate hinge ( 20 ) via a joint ( 32 , 38 ) whose axis (B, C) is arranged transversely to the axis (A) of the gate hinge ( 20 ). 2. Gate fitting according to claim 1, characterized in that between the gate hinge ( 20 , 22 , 24 ) and the joint ( 32 , 38 ) a bolt ( 26 , 30 ) extends adjustably or slidably through the joint ( 32 , 38 ) such that it intersects the joint axis (B, C) at a right angle. 3. Gate fitting according to claims 1 and 2, characterized in that when the ground is rising, the lower fitting, and when it is falling, the upper fitting, has a bolt ( 30 ) which has a longer sliding surface for sliding through an opening ( 40 ) in the joint ( 38 ) before the sliding path beyond the opening ( 40 ) is limited in a fixable manner ( 42 ). 4. Gate fitting according to claim 3, characterized in that the opening ( 40 ) has a larger tolerance in its radial diameter for the sliding through of the longer sliding surface. 5. Gate fitting according to claim 3, characterized in that for larger rises or falls of the ground, a flexible axis is arranged at the root of the bolt ( 30 ) in the hinge ( 22 ) transversely to the hinge axis (A).
