Folding device with locking means

摘要

The disclosure relates to a folding device with locking mechanism for connecting components which is intended for a bicycle and has, on one side, a swing-action articulation and, on the other side, a locking mechanism which contains a locking assembly, which is connected in a rotatable manner to a supporting element and is braced against a curved clamping surface of a clamping element arranged on the opposite side, the clamping surface running eccentrically in relation to the axis of rotation of the locking assembly. The extended axis of rotation of the locking assembly, in the locked state of the folding device, is located within the circle described by the radius of curvature of the clamping surface, and this allows a large clamping displacement. An adjusting nut adjusts the pressure to which the clamping surface is subjected in the locked state by the locking assembly.

主权项

1. A folding device for a bicycle for connecting a first component and a second component of a frame or of a steering rod, comprising:
a first hinge element disposed on a hinge side of the first component; a second hinge element disposed on a hinge side of the second component, the first hinge element and the second hinge element being rotatably connected about a common axis; and a locking mechanism disposed opposite the hinge side of the first component comprising
a supporting element connected with the first component,a locking assembly rotatably connected to the supporting element, anda clamping element connected to the second component, the clamping element having a clamping surface which is outwardly curved and cylindrical, wherein the locking assembly is coming into contact with the clamping surface when the locking assembly is rotated towards the clamping surface in a locked state and wherein in the locked state the locking assembly exerts a force onto the clamping surface, causing the first component and the second component to be firmly connected, and wherein the clamping surface is arranged eccentric relative to a rotational axis of the locking assembly and in the locked state the rotational axis of the locking assembly lies inside a circle that is defined by a radius of curvature of the clamping surface.
