Alarm arrangement for a timepiece
First Claim
1. An alarm timepiece comprising:
- support means;
a dial borne by said support means;
a shaft rotatably mounted on said support means;
a going train operatively mounted on said support means and comprising a plurality of wheels including an hour wheel and a minute wheel, said hour wheel and said minute wheel being rotatably mounted around said shaft;
an hours hand and a minutes hand coupled to said hour wheel and said minute wheel, respectively, so as to cooperate with said dial to display time;
a first contact point rigid with one of said wheels of said going train;
a member fixed to said shaft for rotation therewith;
a second contact point coupled to said member;
manual control means operatively coupled to said member for setting the position of said member and said second contact point, said position being representative of the alarm time at which an alarm must be triggered;
an index coupled to said manual control means for displaying said alarm time; and
,alarm-producing means for producing an alarm when the positions of said first and second contact points coincide with one another by virtue of rotational movement of said one of said wheels with respect to said member.

Abstract
The alarm arrangement is among those in which an alarm is released by the coincidence of a first contact point coupled to the going train of the timepiece with a second contact point coupled to an index the position of which may be regulated by a manual control element. In this arrangement the second contact point (68) is coupled to a member (60) fixed to a rotating shaft (58) on which are pivoted wheel sets (76, 92) of the going train which bear time indicating hands (82, 100). In a very simple case the member fixed to the rotating shaft is adjacent the timepiece hour wheel (80) and the contact points (68, 90) are borne by these two elements on their faces and facing one another. On the other hand the manual control element may be advantageously formed by the glass (16) of the timepiece which is then coupled to one of the ends of the rotating shaft and a rotatable bezel (22) to which the glass is fastened.

14. An alarm timepiece comprising:
-
a support means; a shaft rotatably supported on said support means; a going train operatively mounted on said support means and comprising a plurality of wheels including an hour wheel and a minute wheel rotatably mounted around said shaft; a first contact point on one of said wheels of said going train; a member fixed to said shaft for rotation therewith; a second contact point on said member; alarm-producing means for producing an alarm when said first and second contacts touch; and
,a manual control means for setting an alarm time, said manual control means comprising rotatable bezel mounted on said support means and a glass fixed to said bezel and coupled to one end of said shaft whereby rotation of said bezel sets the position of said second contact, said position representing the time at which the alarm-producing means produces the alarm. - View Dependent Claims (15, 16, 17, 18)

19. An alarm timepiece comprising:
-
a support means; a shaft rotatably supported on said support means; a going train operatively mounted on said support means and comprising a plurality of wheels including an hour cannon wheel and a minute cannon wheel; said hour cannon wheel being rotatably mounted about said shaft and having a pipe, said minute cannon wheel being rotatably mounted about said pipe; a first contact point on one of said wheels of said going train; a member fixed to said shaft for rotation therewith; manual control means for setting said member to a position representative of an alarm time; a second contact point on said member; and
,alarm-producing means for producing an alarm when said first and second contacts touch. - View Dependent Claims (20, 21)
