Abstract

A fitting ( 1 ) for suspending a sliding door leaf (D) is provided. Said fitting ( 1 ) comprises a base plate ( 2 ) having means ( 8, 9 ) for attaching said base plate ( 2 ) to a door leaf (D), support means ( 3 ) attached to said base plate ( 2 ) for allowing said fitting ( 1 ) to be guided by a rail (R) along a sliding path (P), and a shank ( 5 ) having a part ( 5 b, 5 d ) extending from a lateral end of said base plate ( 2 ) at an angle (α, β) relative a plane of the base plate. Said fitting ( 1 ) further comprises an anti-lifting device ( 4 ) attached to said shank ( 5 ) and being moveable between an idle position and a locked position by a rotational movement of the anti-lifting device ( 4 ) about an axis (A) being substantially perpendicular to a plane of said shank part ( 5 b, 5 d ).

First claim

The invention claimed is:

1. A fitting for suspending a sliding door leaf, said fitting comprising:
a base plate having at least one element for attaching said base plate to the door leaf,
a support mechanism attached to said base plate for allowing said fitting to be guided by a rail along a sliding path,
a shank having a part extending from a lateral end of said base plate at an angle relative to a plane of the base plate, and
an anti-lifting device attached to said shank and being moveable between an idle position and a locked position by a rotational movement of the anti-lifting device about an axis being substantially perpendicular to a plane of said shank part, and wherein the anti-lifting device is provided with a catch member for engaging a hook of a self-closing mechanism,
wherein the shank is provided with a protrusion and the anti-lifting device is provided with a matching recess configured to define the idle position and the locked position, the recess extending semi-circularly around the rotational axis of the anti-lifting device and comprising a ridge configured to provide for snap-locking of the protrusion in said locked position, and
wherein when the anti-lifting device is in the locked position, a distal end of the anti-lifting device is positioned below the support mechanism forming a vertical gap between the distal end of the anti-lifting device and the support mechanism for accommodating the rail.

2. A fitting according to claim 1 , wherein said angle is between 45° and 135° relative to a transversal direction of the plane of the base plate, and between 45° and 135° relative to a longitudinal direction of the plane of the base plate.

3. A fitting according to claim 1 , wherein said anti-lifting device is arranged at a first longitudinal distance from said support mechanism when the anti-lifting device is in its idle position, and said anti-lifting device is arranged at a second longitudinal distance from said support mechanism when the anti-lifting device is in its locked position, wherein the second longitudinal distance is smaller than the first longitudinal distance.

4. A fitting according to claim 1 , wherein said support mechanism is a roller.

5. A fitting according to claim 1 , wherein said element for attaching said base plate to a door leaf comprises at least one through hole for receiving a fastener.

6. A fitting according to claim 5 , wherein said at least one through hole has a longitudinal extension being slightly larger than a lateral extension for allowing vertical adjustment of the fitting relative the door leaf.

7. A fitting according to claim 5 , further comprising at least one eccentric configured to engage a bore of a door leaf for allowing further vertical adjustment of the support mechanism relative the door leaf.

8. A fitting according to claim 1 , wherein said shank comprises a first part being attached to said base plate and extending substantially parallel to said base plate, and a second part extending from said first part at said angle relative the plane of the base plate.

9. A fitting according to claim 1 , wherein said shank comprises a first part being attached to said base plate and extending substantially parallel to said base plate, a second part extending from said first part at said angle relative the plane of the base plate, a third part extending from said second part and being substantially parallel to said first part, and a fourth part extending from said third part at said angle relative the plane of the base plate.

10. A door leaf in combination with a fitting for suspending the door leaf, said fitting comprising:
a base plate having at least one element for attaching said base plate to the door leaf,
a support mechanism attached to said base plate for allowing said fitting to be guided by a rail along a sliding path,
a shank having a part extending from a lateral end of said base plate at an angle relative to a plane of the base plate, and
an anti-lifting device attached to said shank and being moveable between an idle position and a locked position by a rotational movement of the anti-lifting device about an axis being substantially perpendicular to a plane of said shank part, and wherein the anti-lifting device is provided with a catch member for engaging a hook of a self-closing mechanism,
wherein the shank is provided with a protrusion and the anti-lifting device is provided with a matching recess configured to define the idle position and the locked position, the recess extending semi-circularly around the rotational axis of the anti-lifting device and comprising a ridge configured to provide for snap-locking of the protrusion in said locked position, and
wherein when the anti-lifting device is in the locked position, a distal end of the anti-lifting device is positioned below the support mechanism forming a vertical gap between the distal end of the anti-lifting device and the support mechanism for accommodating the rail.

11. A sliding door system in combination with a guiding rail, at least one door leaf, and a fitting for suspending the at least one door leaf, said fitting comprising:
a base plate having at least one element for attaching said base plate to the door leaf,
a support mechanism attached to said base plate for allowing said fitting to be guided by a rail along a sliding path,
a shank having a part extending from a lateral end of said base plate at an angle relative to a plane of the base plate, and
an anti-lifting device attached to said shank and being moveable between an idle position and a locked position by a rotational movement of the anti-lifting device about an axis being substantially perpendicular to a plane of said shank part, and wherein the anti-lifting device is provided with a catch member for engaging a hook of a self-closing mechanism,
wherein the shank is provided with a protrusion and the anti-lifting device is provided with a matching recess configured to define the idle position and the locked position, the recess extending semi-circularly around the rotational axis of the anti-lifting device and comprising a ridge configured to provide for snap-locking of the protrusion in said locked position, and
wherein when the anti-lifting device is in the locked position, a distal end of the anti-lifting device is positioned below the support mechanism forming a vertical gap between the distal end of the anti-lifting device and the support mechanism for accommodating the rail.

12. The fitting of claim 2 , wherein the angle is 90° relative to a transversal direction of the plane of the base plate.

13. The fitting of claim 2 , wherein the angle is 90° relative to a longitudinal direction of the plane of the base plate.
