Method and a device for hooking a balloon envelope to a fastener means
First Claim
1. A method for hooking an envelope comprising a flexible sheath (1) to a fastener device, comprisingprovided a fastener (2) made of rigid material having an outer peripheral side provided with an annular groove (3),tightening the sheath at the fastener (2) and locking the sheath in place in such a manner that it follows the shape of the groove (3) of said fastener by means of a tightening collar (4) made of a substantially inextensible material having high tensile strength and a cross-section designed to fill the annular groove to a specific depth,placing an annular seal extending over the entire periphery of the tightening collar (4) and in contact with the outer peripheral side (4a) of said collar,maintaining said annular seal (5) in place over substantially all of its outer peripheral side (5a) by a retaining strap (6) of a substantially inextensible material having high tensile strength and adapted to guide the deformation of said annular seal in a preferred direction for compressing the sidewalls (3a) of said annular groove (3),whereby said seal may undergo compressive radial deformations for imparting to said tightening collar a degree of freedom with respect to the sidewalls (3a) of the groove (3) averting compressive force on said collar.

Abstract
A method for hooking a flexible envelope to a fastener device, comprising employing an annular and rigid fastener (2), provided with an annular groove (3) on its outer peripheral side, tightening the sheath at the fastener (2) and locking it in place in such a manner that it assumes the shape of the groove (3) by means of a tightening collar (4) comprising a cable made of a substantially inextensible material of high tensile strength and wound inside said groove to a specific height within it, and placing an annular seal (5) in contact with the outer peripheral side (4a) of the tightening collar (4), whereby this seal (5) when compressed may deform radially in order to provide the tightening collar with a degree of freedom with respect to the groove sidewalls (3a); and a hooking device for use with the method.

- 11. A fastener for attaching to an envelope (1) made of a flexible sheath comprising an annular fixation part (2) made of a rigid material and with an outer peripheral side having an annular groove (3) for acting as a housing for locking the sheath, a tightening collar (4) to tighten the sheath and located in the annular groove (3) formed by a cable made of a substantially inextensible material of high tensile strength wound inside and to a specific depth of the said groove, an annular seal (5) located in said groove around said outer peripheral side (4a) of said tightening collar (4), and a retaining strap (6) made of a substantially inextensible material of high tensile strength and wound around said annular seal (5).
