Abstract
According to the invention is realised a length regulating device for cords holding up spectacles, constituted by a pair of cases (3) of preferably prismatic shape, each of which comprises at least one external element (5) for application of the case to the crosspiece (4) of a pair of spectacles; an elastic reaction unit (10) disposed within the case (3) on which is wound up a portion of the length of a spectacles-supporting cord (2); a small square (22) for braking the cord (2). The lengthening of the cord (2) is effected by extension of the elastic reaction unit (10) when traction (30) is applied to the cord (2), while the shortening of the cord (2) is effected by return of said elastic reaction unit (10) when the application of the traction force (30) to the cord ceases. The entity for lengthening or shortening may be regulated by means of braking locking means (22).
