  • Patent number: 11965368
    Abstract: A sliding door roller fitting includes a tilting lever having a long and short arm angled thereto. The long arm has a freely rotatably mounted running roller which projects beyond the long arm to roll along a running rail. The short arm has an outwardly curved outer side facing away from the running roller. The tilting lever is held on a sliding door-side bearing body and is tiltable between two end positions about a tilting axis parallel to a running roller tangent. The bearing body has at least one planar bearing surface which extends horizontally in the setting-out direction in the mounting position of the bearing body. The short arm of the tilting lever bears by its curved outer side against the bearing surface and rolls thereon during tilting of the tilting lever. The bearing body has two driving stops between which the tilting lever is arranged.

  • Patent number: 11703073
    Abstract: A connection bolt for connecting two parts, in particular furniture panels, includes a cylindrical bolt shaft for anchoring in a bore of the one part and a bolt head for anchoring in a bore of the other part. The bolt head has a foot portion, which adjoins the bolt shaft, and a hook-shaped head portion with a radially outwardly projecting, blade-shaped projection. The foot portion is arranged with respect to the bolt shaft eccentrically offset in the radial direction in which the projection projects radially outwards.

  • Publication number: 20230096589
    Abstract: A fitting for connecting two parts includes a cup-shaped housing for insertion into an open-edge bore in the one part. Two double-armed levers are connected in an articulated manner about an axis running, in the housing, parallel to the cup axis and which each have an inner lever arm which is arranged in the housing and an outer lever arm which projects outwards beyond the circumference of the housing and is intended for engaging in a surface-area bore in the other part. A handle can be moved from a starting position into an end position and has an actuating element for rotating the inner lever arms in relation to one another such that the two outer lever arms are spread further apart in the end position of the handle than in the starting position.
