Abstract
An attachment device for tightening an adjustable resistant strap, comprising a buckle composed of a pair of superposed rings of different dimensions. The buckle is associated with a positioning shim housed around a closed first turn arranged opposite the blocking slot of the strap. The positioning shim is configured to separate the top strand and the bottom strand of said turn from one another. This results in a reduction of the friction effect when relative movement takes place between the two rings. The shim is equipped for this purpose with two guide apertures through which the bottom strand and the top strand of the closed turn attached to the buckle respectively pass.
Claims9
An attachment device with a buckle for adjusting and clamping a strap, said buckle being composed of a pair of superposed rings presenting rectangular frames of different dimensions, the larger first ring comprising a first rectangular opening located under a second rectangular opening arranged in the second ring of smaller size so as to define a transverse slot for passage of the strap, said slot being arranged between one of the outer edges of the second ring, and the adjacent side of the first opening of the first ring, the buckle being located either in a blocking position of the strap in the slot when tensioning is performed, or in a releasing position after a relative movement between the two rings resulting in an increase of the passage area in the slot,
- wherein the buckle is associated with a positioning shim housed opposite the slot, surrounding a first closed turn of the strap, said positioning shim separating the top strand and the bottom strand of said turn from one another to reduce the friction effect when relative movement takes place between the two rings.
