Abstract
The present invention concerns a timepiece having an alarm activating mechanism that serves for effecting the closure of an electrical contact (5a, 9) at a time which is adjustable in advance. The mechanism is arranged in the form of a module (100) which comprises a mechanically unitary assembly formed of two coaxial wheels (6, 8), one of which carries a contact element (9). This unitary assembly is mounted on the framework of the movement so that its angular position is manually adjustable about an axis, and it carries a wheel (5) which is in mesh with the hour wheel (3) and has an embossment (5a) which can enter into contact with the contact element (9). The invention is applicable more particularly to alarm watches.
Claims13
A timepiece comprising:
- a framework;
- means, rotatably mounted on said framework, for displaying the present time;
- movement means mounted on said framework for actuating said means for displaying;
- modular alarm activating means, rotatably mounted on but removable as a module from said framework, for closing an electric contact at a time which can be set in advance, said modular activating means comprising a first support member mounted on said framework for rotation about a first axis, a first electrical contact member mounted on said first support member for rotation therewith about said first axis, a second support member mounted on and about said first support member for rotation about said first axis relative to said first support member, said second support member being operatively connected to said movement means, a second electrical contact member mounted on said second support member for rotation therewith about said first axis, said second contact member being in position to be rotated into contact with said first contact member to activate an alarm and means for inseparably holding said second support member on said first support member to permit removal of said alarm activating means as a module from said framework;
- and
- means mounted on said framework for rotating said first support member of said modular activating means to position said first contact member at a location corresponding to a desired alarm time,
- whereby said first and second contact members are brought into contact when said support member has been rotated by said movement means until said second contact member reaches said location corresponding to said desired alarm time.
A timepiece comprising:
- a framework having a circular opening;
- means, rotatably mounted on said framework, for displaying the present time;
- movement means mounted on said framework for actuating said means for displaying;
- modular alarm activating means, rotatably mounted on but removable as a unit from said framework, for closing an electric contact at a time which can be set in advance, said modular activating means comprising a first toothed wheel having a cylindrical portion extending from one side thereof into said circular opening to rotatably support said modular alarm activating means in said framework for rotation about a first axis, a first electrical contact member mounted for rotation with said first toothed wheel, a second toothed wheel connected to said first toothed wheel, said second toothed wheel having a pipe engaged with the other side of said first toothed wheel so that said first and second toothed wheels rotate together about said first axis, a support member mounted unseparably on said pipe for rotation about said first axis, said support member being operatively connected to said movement means, and a second electrical contact member mounted for rotation with said support member in position to be rotated into contact with said first contact member to activate an alarm;
- and
- means mounted on said framework for rotating said first toothed wheel of said modular activating means to position said first contact member at a location corresponding to a desired alarm time,
- whereby said first and second contact members are brought into contact when said support member has been rotated by said movement means until said second contact member reaches said location corresponding to said desired alarm time.
