Description
Pièce d'horlogerie. L'objet de la présente invention est une pièce d'horlogerie du type puisant sa force motrice dans une source d'énergie lumineuse en faisant intervenir au moins une cellule photoélectrique.
Par pièce d'horlogerie, au sens de la pré sente invention, il faut entendre tout instru ment propre à marquer les heures.
Dans une pièce d'horlogerie dont la mar che dépend de la présence d'énergie lumi neuse, il est nécessaire de prévoir une réserve d'énergie, destinée à suppléer à l'absence de lumière, par exemple la nuit.
On a déjà proposé à cet effet d'armer un ressort de barillet, de soulever une masse, en un mot, d'accumuler de l'énergie mécanique sus ceptible d'être rendue au mouvement lorsque la lumière manque ou devient insuffisante.
Selon la présente invention, l'énergie élec trique est acciunLdée au moins à un moment donné sous forme électrique.
Pour ce faire, les cellules photoélectriques seront reliées soit à demeure, soit temporaire ment<B>à</B> un accumulateur électrique.
Dans le premier cas, elles n'auront pour fonction que de charger l'accumulateur, d'où l'énergie sera prise pour actionner le mouve ment soit en armant un ressort de barillet ou en soulevant une masse par l'intermédiaire d'un moteur par exemple, soit en actionnant un pendule, un dispositif oscillant, etc.
Dans le second cas, l'énergie provenant des cellules photoélectriques aurait pour mission première d'agir sur des moyens d'entraîne ment mécaniques, et chargerait accessoirement un accumulateur, afin de constituer une ré serve pour leurs périodes d'inaction.
Il pourrait, par exemple, être prévu un moteur armant un ressort de barillet et un commutateur- disjoncteur automatique, con duisant l'énergie à l'accumulateur dès le mo ment où. le ressort serait complètement armé. La même disposition pourrait être adoptée en remplaçant le ressort par un poids, dont la position haute correspondrait alors au ressort armé.
Timepiece. The object of the present invention is a timepiece of the type drawing its driving force from a source of light energy by bringing in at least one photoelectric cell.
By timepiece, within the meaning of the present invention, is meant any instrument suitable for marking the hours.
In a timepiece whose rate depends on the presence of light energy, it is necessary to provide an energy reserve, intended to make up for the absence of light, for example at night.
It has already been proposed for this purpose to arm a barrel spring, to lift a mass, in short, to accumulate mechanical energy capable of being returned to the movement when the light is lacking or becomes insufficient.
According to the present invention, electrical energy is stored at least at one time in electrical form.
To do this, the photoelectric cells will be connected either permanently or temporarily <B> to </B> an electric accumulator.
In the first case, their function will only be to charge the accumulator, from where the energy will be taken to activate the movement either by charging a barrel spring or by lifting a mass by means of a motor for example, or by activating a pendulum, an oscillating device, etc.
In the second case, the energy coming from the photoelectric cells would have the primary mission of acting on mechanical drive means, and would incidentally charge an accumulator, in order to constitute a reserve for their periods of inaction.
For example, a motor could be provided to charge a barrel spring and an automatic circuit breaker switch, conveying energy to the accumulator as soon as possible. the spring would be fully loaded. The same arrangement could be adopted by replacing the spring with a weight, the high position of which would then correspond to the armed spring.
