Abstract

A fastening device for assembly and quick release between objects includes a retaining device for an attachment element with a dockable portion. There is a plurality of separable parts held close together around the attachment element by at least one disengageable preloading mechanism. The preloading mechanism includes a link wound around the separable parts in order to hold them closed on the attachment element, which has the appearance of a ribbon wound in a spiral and has spring properties. The ribbon has a non-constant thickness, i.e. the thickness decreases from the inside towards the outside of the spiral. The thickness decreases with the angle of the spiral. It is manufactured as such, in its final form, by a manufacturing process employing either the removal of material by machining, or by aggregation of material.

IPC Classes  ?

• F16B 2/06 - Clamps, i.e. with gripping action effected by positive means other than the inherent resistance to deformation of the material of the fastening external, i.e. with contracting action
• F16F 1/10 - Spiral springs with turns lying substantially in plane surfaces
• F16F 1/12 - Attachments or mountings

Abstract

Fastening device for assembly and quick release between objects, formed of a retaining means (3) designed to retain, before releasing, an attachment element (R), and consisting of bringing together, around a dockable portion of said attachment element, a plurality of separable parts (30) held close together around said attachment element (R) by means of at least one disengagable preloading mechanism (2) that consists of a link wound around the separable parts (30) in order to hold them closed on the attachment element, which has the appearance of a ribbon wound in a spiral and has spring properties. The ribbon (2) has a non-constant thickness, i.e. the thickness decreases from the inside towards the outside of the spiral, said thickness decreasing with the angle of the spiral. It is manufactured as such, in its final form, by a manufacturing process employing either the removal of material by machining, or by aggregation of material.

IPC Classes  ?

• B64G 1/22 - Parts of, or equipment specially adapted for fitting in or to, cosmonautic vehicles
• F16F 1/10 - Spiral springs with turns lying substantially in plane surfaces
