Abstract
A timepiece has a counting mechanism for counting the oscillations of the oscillating regulating member. The counting mechanism includes a plastic block with a retaining pawl and a driving pawl embedded within it. The block has a notch whose two walls serve to limit the movement of a first portion of the driving pawl which is embedded by one extremity in the block and passes through the notch to an elbow formed in the driving pawl which cooperates with the oscillating member to drive a ratchet wheel by a second driving portion of the driving pawl. The retaining pawl has one extremity embedded in an elastic portion of the block and the other cooperates with the ratchet. The block has an eccentric member abutting the elastic portion to adjust the position of the retaining pawl.
Claims4
A timepiece having a frame and having an oscillating regulating member, the oscillations of which are counted by means of a click counting mechanism including a ratchet wheel submitted to the action of a driving pawl and a retaining pawl, said click counting mechanism comprising:
- two metallic blades constituting respectively said driving pawl and said retaining pawl,
- said driving blade being bent at substantially a right angle forming two portions with an elbow therebetween and being secured to said frame by an end of one of its portions and cooperating by the opposite end of said portion, substantially at said elbow, with said oscillating regulating member, which member imparts a back and forth movement to said driving blade, a free end of the second portion of said driving blade cooperating with said ratchet wheel.
A timepiece having a frame and having an oscillating regulating member, the oscillations of which are counted by a click counting mechanism including a ratchet wheel driven by a driving pawl and a retaining pawl, said click counting mechanism comprising:
- a block made of plastic material, mounted on the frame of the timepiece, said block having a notch provided therein having two walls, and said block having an elastic portion which cooperates with an adjustable eccentric abutting member carried by said block, and having two metallic blades embedded by a first extremity in said block;
- a first one of said blades acting as said driving pawl and having a first portion extending through said notch from said embedded extremity, having a substantially right angle bend forming an elbow outside said notch, a second portion extending from said elbow and having a free extremity, said blade cooperating substantially at said elbow with said oscillating regulating member which imparts a back and forth movement to said blade, with the movement limited by said walls of said notch, said free extremity of said second portion driving said ratchet wheel;
- and
- a second one of said blades acting as said retaining pawl, said first extremity embedded in said elastic portion of said block and a second extremity cooperating with said ratchet wheel, the position of said second blade being adjustable by adjusting said eccentric abutting member.
