81	BARREL SPRING	US13700197	2011-05-23	US20130083633A1	2013-04-04	Pascal Winkler; Yvan Teres
A barrel spring (10) for a mechanism driven by a mainspring, in particular for a timepiece, includes a unitary ribbon of metallic glass. The object is to integrate at least one additional function to the spring function, implemented by a functional portion integrated in the spring.

A spring device having an inside-end wheel that moves in conjunction with the inside end of a mainspring; an outside-end wheel that moves in conjunction with the outside end of the mainspring; a torque return unit that transfers part of the output torque of the mainspring from one to the other of the inside-end wheel and outside-end wheel; a duration time indicating unit that operates in conjunction with both the inside-end wheel and outside-end wheel and indicates the number of winds in the mainspring; and a torque transfer clutch unit that disengages torque transfer between the inside-end wheel and outside-end wheel by means of the torque return unit when the mainspring unwinds and the duration time indicating unit indicates a predetermined reference number of winds.

A timepiece includes a flexible endless ribbon (10) bearing time indications (13, 14) and stretched between two parallel rollers (11, 12), and a mechanism for turning at least one of these rollers including a spring wound up inside a barrel, an escapement and a regulator member coupled to the escapement. The spring is wound up inside at least one of the rollers which thus forms the barrel of the drive mechanism.

A fourth wheel 8 disposed in a torque transmission path and to which a second hand is mounted includes a pinion 8a and a gear 8b. Therefore, when the gear 8b engages a fifth-wheel first intermediate wheel 9, the diametrical dimension from a center of rotation of the fourth wheel 8 to a portion where it engages the fifth-wheel first intermediate wheel 9 can be made large, so that, even when the fourth wheel 8 is decentered, the amount by which the second hand gets shifted can be made small by making the effects of the decentering at the center-of-rotation side small. In addition, since the fourth wheel 8 is disposed so as not to overlap a mainspring 1a, the width of the mainspring 1a can be made correspondingly small. Thus, the length of time a timepiece continues operating can be increased by increasing the torque of the mainspring 1a without increasing the thickness of the entire timepiece.

A spring device comprises at least one elastic band which, in released or wound-up position, is rolled against the inside of an outer path and, in wound-up or released position, respectively, is rolled on the outside of a drum which is positioned within the outer path and is rotatable relative thereto. The band is adapted, as it is unrolled from the drum or vice versa, by the action of two or more members which are spaced at least substantially evenly along the periphery of the drum, to maintain its rolled-up position on respectively the outside of the drum and the inside of the outer path to a point from which it directly passes to, and is rolled up on respectively the inside of the outer path and the outside of the drum.Spring devices of spiral as well as helical type, such as clock springs and roller blind springs, respectively, often have a disadvantage in that the spring force or, more exactly, the torsional moment usually varies substantially linearly from a maximum value when the spring is entirely wound up, to zero when the spring is entirely released. This disadvantage is overcome by the present invention acccording to which the moment either is kept constant throughout the working cycle or has a special variation, e.g. it increases towards the end of the working cycle, which is suitable for roll type belts.

The present invention relates to a timepiece escape mechanism sub-assembly (1) including at least one bar (3) and at least one balance spring (71). The outer end of the at least one balance spring is fixed to a balance spring stud (73). The at least one balance spring (71) and the balance spring stud (73) associated therewith form a single-piece assembly with the bar (3).
