Definitions

  • the present invention relates to a timer switch for programming the energization/de-energization time intervals of relays and the like, according to the preamble of claim 1.
  • timer or clock switches are known, it being possible to program said switches so as to send an energization signal to a relay controlling higher-capacity electrical equipment at predetermined time intervals and vice versa de-energize the relay itself during other time intervals.
  • rider clocks are widely used, these being basically electro-mechanical timing mechanisms in which the relay energization signal is maintained during the time period set by the user via mechanical arms which are referred to as "riders”.
  • raising/lowering the riders causes energization/de-energization of the relays commanding the equipment to be controlled.
  • Said rider clocks have several drawbacks including the large number of mechanical parts such as: riders, levers, drive mechanisms, toothed wheels and transmission spindles, which are particularly difficult to manufacture, assemble and test since they require specially designed equipment and moulds as well as specialized personnel.
  • said mechanical parts are made of plastic which is subject to wear with time, hence requiring the need for spare-parts warehouses with a consequent increase in the costs.
  • a further limitation of the aforementioned rider clocks consists in the fact that subdivision of the time period which can be programmed for energization/ deenergization is limited by their physical dimensions, thus making it necessary to manufacture many types of switches with different configurations and sizes according to the time period to be programmed, without, however, the possibility of switching from one programming period to another unless the type of switch is changed - something which is not always possible owing to the different dimensions of the said switches.
  • the technical problem which is posed, therefore, is that of providing a programmable timer switch, consisting of a small number of parts, with a low cost and small dimensions, which allows easy programming of the operating time and moreover allows one to have the possibility of programming both whole time periods and fractions thereof, without the need for further parts and/or mechanisms.
  • the timer switch is composed of a container 1 closed at the bottom by a base-piece 1a which has mounted on its internal surface a screen 2 providing protection against electro-magnetic interference; the base-piece 1a is provided moreover with extensions 2a for supporting a printed circuit 3b which has incorporated in its upper surface a liquid-crystal display 3 containing segments 3a arranged in two concentric rings, as illustrated in Figure 1 and for the purposes which will become clear in the description below.
  • the liquid-crystal display 3 comprises, configured in a so-called seven-code arrangement, segments for forming the digits 5a of a digital clock 5 (Fig. 1) which counts the minutes and a further clock 14 which counts the days.
  • the liquid crystals are protected at the top by a small pane of glass 4 or similar transparent material fixed to corresponding seats on the casing 1.
  • the upper surface 1c of the casing 1 moreover has formed in it openings 6 designed to accommodate buttons 7, 8 and 9 acting on suitable contact zones of a rigid printed circuit 10 electrically connected to the digital display 3 by means of a first flexible connecting printed circuit 11 which also has on it a microprocessor 13 which programs the time interval set for energization of the relay 15.
  • buttons 7 and 8 are used for programming the hourly period and/or for a fraction thereof, so as to obtain a programmable time interval which is as small as possible and increase the programming possibilties, as will be further described below.
  • buttons 9, on the other hand, are used to adjust and start the digital clock 5 using techniques and procedures which are known per se and therefore not further described and illustrated.
  • the hour counter comprises a further flexible printed circuit 12 which is connected to the relay schematically indicated by 15, for programmed energization/de-energization thereof.
  • the hour counter operates as follows: after starting and adjusting via the buttons 9 both the digital clock 5 and the day counter 14, programming of the periods for activation of the relay is performed by pressing the buttons 7 and 8, in particular:
