Patent number: 7384190Abstract: The present invention concerns a crown for a timepiece comprising a disconnecting gear device for preventing damage to the components of the movement of the timepiece in which it is implemented. For this purpose, the crown is provided with a housing which houses a pipe, to which one end of a winding stem is connected, carrying at least one spring and a rigid ring secured to the crown and comprising notches adapted to cooperate with the spring. In common use, a rotation of the crown causes a rotation of the pipe and thus of the winding stem, via the rigid ring and the spring. Owing to the device according to the present invention, when the mechanical resistance to the rotation opposed by the winding stem, via the pipe, exceeds a predefined threshold, the spring is deformed and is no longer driven in rotation by the rigid ring. Consequently, the winding stem is no longer driven in rotation in such conditions.Type: GrantFiled: April 5, 2005Date of Patent: June 10, 2008Assignee: Meco SAInventor: Georges Zimmermann

Patent number: 6872899Abstract: There is provided a button capable of entry and exit with respect to a base. The button has a button member, ring member, lock member, and fixed member. The button member has a shaft portion mounted in a manner that allows entry and exit with respect to the base, and an expanded-diameter portion with a shaft diameter that is larger than the diameter of the shaft portion. The ring member accommodates the shaft portion and can rotate about the axial center of the shaft portion. The lock member moves along the axial center between the ring member and the shaft portion due to the rotation of the ring member, and restricts the entry and exit action of the button member by coming into contact with the expanded-diameter portion of the button member. The fixed member is fixed to the base and stops the ring member to restrict the movement of the ring member along the axial center.Type: GrantFiled: March 31, 2004Date of Patent: March 29, 2005Assignee: Seiko Epson CorporationInventors: Takumi Oshio, Kowk Fai Lam

Patent number: 6830371Abstract: An accuracy adjustment apparatus for a timepiece has an accuracy adjustment data input control section including a case-mounted switch such as a crown of the timepiece. A crown state detection signal is used to determine the state of the crown. When an accuracy adjustment data input mode is indicated based on the position of the crown, an indicator of the timepiece is driven to provide a visual indication of accuracy adjustment data selectable by operation of the crown. When the proper accuracy adjustment data has been selected, the data is stored to a memory.Type: GrantFiled: August 31, 2002Date of Patent: December 14, 2004Assignee: Seiko Instruments Inc.Inventor: Hiroyuki Masaki

Patent number: 6639874Abstract: A pointer electronic timepiece (1) has a plurality of step motors, a plurality of pointers (11 to 18), and a plurality of external operation members of a winding crown (5) and buttons (6, 7). The pointer to be adjusted is selected from the plurality of pointers (15 to 18) by operating one of the buttons (6) while drawing out the winding crown (5) to a second stage and the other button (7) is operated to adjust the position of the selected pointer. Since the position of the pointers (15 to 18) driven by three step motors can be adjusted by the two buttons (6, 7), the number of the external operation member is not necessary to be increased even when the pointers (15 to 18), i.e. the step motors, are increased, so that the size and thickness of a movement-holder and cost thereof can be reduced and operability during adjustment can be improved.Type: GrantFiled: July 3, 2001Date of Patent: October 28, 2003Assignee: Seiko Epson CorporationInventors: Eisaku Shimizu, Akihiko Maruyama
