ABSTRACT:
To provide for vibration-resistant, self-centering, and universal attachment of an accessory such as a luggage carrier (3) or a kickstand (4) to essentially parallel or slightly divergent support struts (8, 12) of a cycle, such as a bicycle, moped, and the like, an attachment element is formed with a central portion (18) and two lateral flange or wing portions (19, 21), the central portion having a bore (24) extending therethrough. The flange portions (19, 21) are similar wedge-shaped elements with upper and lower surfaces diverging from outer end portions (33, 34) towards the central portion (18) to define, in cross section in a plane parallel to the axis of the aperture and transverse to the struts, triangular elements having bases (22, 23) adjacent the central portion, which bases may be extended into ribs if the wing or flange portions and the central portion are formed with hollows. The flange portions are elastically deformable in a direction parallel to the axis of the bore, which deformability is assisted by forming the flange or wing portions as hollow triangle-prismatic structures. Preferably, a groove is cut in the central portion, dimensioned to receive a hexagonal nut so that a bolt can be threaded into the element without requiring a holding wrench. The element can be made by being cut from a long aluminum profile rail, or by pressure casting.
