Definitions

  • At least one control lever is attached to said supporting member, and is operated by its abutment with the clock bearing plane because of said oscillation, the base shape and counterweight position being such as to cause the clock to move back to and be held at its balance position, when the disturbing action is stopped or removed.
  • This invention relates to table-clocks, more particularly alarm-clocks, taking advantage of a disturbance in balance thereof to operate one or more levers acting on the inner devices of the .clock.
  • the clock supporting base comprises two or more suitably interhinged elements, so that the relative movement thereof, as due to an external manual operation, may be taken advantage of for functional purposes.
  • An exemplary system of this kind is to be found in alarm-clocks, where a manual pressure on a determined location of the clock would serve for stopping the sound of the alarm device.
  • the clocks of the above-described type have the practical disadvantage of a poor stability, particularly because of the hinged support, whereby a slight error in operation might cause the clock to fall down.
  • the object of the present invention is to avoid such drawbacks and to provide a table-clock using the artificial center of gravity techniques for obtaining complex functional performances of the clock, such as alarm sound stopping, at the same time avoiding the drawback due to a casual falling of the clock by incorrect operation thereon.
  • the object of the present invention is to provide an alarm-clock comprising a supporting member or casing for the alarm device and a counterweight adjacent the base of said supporting member, the bearing base for said member having an end portion upward facing or connected to the upper portion for enabling said'member to oscillate as a result of a balance disturbing action between a balance position and an inclined position, characterized in that at least one control lever is attached to said supporting member, said lever being operated by its abutment with the clock bearing plane because of said oscillation, the bearing base shape and counterweight position being such that the clock is moved back to and maintained at its balance position, when the disturbing action is removed.
  • FIG. 1 is a longitudinal sectional view showing a first embodiment of the clock according to the present invention at its steady balance position;
  • FIG. 2 is a view similar to FIG. 1, showing the clock at the position for operating the control levers of the inner devices under the action of an external bias;
  • FIG. 3 shows a second embodiment of the clock according to the present invention.
  • the clock substantially comprises a supporting member 1 for the alarm device 2, said supporting member 1 being substantially L-shaped as shown in FIGS. 1 and 2, and at its upper portion bearing said alarm device 2, while incorporating at its lower portion a counterweight 3 acting to provide an artificial center of gravity for the assembly such as to be close to base 4. of member 1.
  • the base 4 for the supporting member I is suitably connected to the upper portion thereof by such a curved length 4f as to aid in clock moving away from balance position, in the direction of arrow 5 shown in FIG. 1, due to an external manual action intended to disturb the static clock balance.
  • lever 6 During the rearward movement of supporting member I, lever 6 will bump into the bearing plane 8; said plane 8 urging the lever against said member 1 and pressing pushbutton 7 for alarm stop.
  • FIG. 3 A further example is shown in FIG. 3, where counterweight 9 has been placed rearwardly of the alarm device 10, but still adjacent the base, so that the movement should be forwardly rather than rearwardly, as in the embodiment of FIGS. 1 and 2.
  • a leverll such as for stopping the alarm device, has been placed on the front portion 12 of the bearing base which, under balance conditions, is upward facing or not contacting the bearing surface 13, this bearing base being convex for enabling the clock to oscillate.
  • the operation is fully identical to that previously described in connection with FIGS. I and 2.
  • a single lever has been provided for stopping the alarm device, it being however understood that the lever can be committed with a task different from that described and that a plurality of levers may be provided for a same clock, each of which operating as previously described and to each of which different tasks are committed, such as the task of connecting or disconnecting a switch, causing a counting system and the like to trigger, and generally operating any additional device (not shown) incorporated in the clock.
  • a housing comprising a base portion and a clock supporting portion forming an angle with said base portion, and being rockable between a normal clock exhibiting position and an angularly offset signal shutoff position,
  • control means operative near said signal shutott position for setting said setting means into its signal inhibiting station
  • said counterweight is positioned on said base portion and spaced a distance sufficient from the vertical line intersecting the center of gravity of said housing in the shutoff position and has a weight sufficient to be operable to return the housing to the normal position.
  • setting means is disposed on the underside portion of said base portion and is operable to protrude outwardly therefrom towards said ground surface.
