Definitions

  • An alarm clock has an alarm device which can be set 52 U5. (:1. 58/21.15 in an operative or an imperative condition by tilting 1] Int. Cl. the clock from one Stable rest position to another [58] Field of Search 58/19, 21.15, 53
  • An object of the invention is to provide an alarm clock in which switching of the alarm device between an operative and an inoperative condition can be achieved simply by tilting the clock between two positions in both of which positions the dial face of the clock is oriented so as to conveniently display the time.
  • An alarm clock comprises a case having a generally planar dial face including time indicating means.
  • the case has discrete first and second rest surfaces defined by first and second planes intersecting at an obtuse angle along a line parallel to the general plane of the dial face, and the dial face includes a major axis lying in a plane perpendicular to the general plane of the dial face and perpendicular to said first and second planes.
  • the first and second rest surfaces respectively form means for supporting the clock on an underlying generally horizontal support surface in stable first and second positions, in both of which first and second positions said plane of the major axis is disposed perpendicular to the underlying support surface.
  • the clock also includes an alarm device and means for switching the alarm device between an operative and an inoperative condition when the clock is moved from one of said first and second positions to the other.
  • FIG. 1 is a schematic cross-section through an alarm clock
  • FIGS. 2 and 3 are schematic side elevational views of the alarm clock in two positions.
  • the alarm clock shown includes a case 1 having discrete first and second planar rest surfaces 2 and 3 respectively, surfaces 2 and 3 intersecting at an obtuse angle along a line parallel to the general plane of a dial face 9.
  • Dial face 9 is covered with a glass 10 and has time indicating means including conventional hands 11 cooperating with marks on the dial face 9.
  • Hands 11 are driven by a schematically shown electric clockwork mechanism 12.
  • the cross-section of FIG. 1 is taken through the major 12 oclock 6 oclock axis of dial face 9, which axis lies in a plane perpendicular to the planes of rest surfaces 2 and 3.
  • the center of gravity (not shown) of the clock is disposed perpendicular to both rest surfaces 2 and 3 whereby the rest surfaces 2 and 3 form means for supa position in which the indicated time can be read conveniently.
  • the clock also includes a schematically shown electric alarm device 4 which is in an operative condition, i.e., able to give a sonorous alarm signal at a preset time, when a contact 6 is closed, and is in an inoperative condition when contact 6 is open.
  • operative condition i.e., able to give a sonorous alarm signal at a preset time, when a contact 6 is closed, and is in an inoperative condition when contact 6 is open.
  • Contact 6 is operated by a push button 5 passing through an aperture 5 in surface 3, button 5 being urged by a compression spring 7 and by a resilient blade 8 of contact 6 from a retracted position (FIGS. 1 and 2 in which the button 5 is flush with the surface 3, to a withdrawn position (FIG. 3) in which it protrudes from surface 3.
  • button 5 When the clock is placed with its rest surface 2 on a horizontal underlying support face 13, button 5 is free to move out to its withdrawn position, as shown in FIG. 3. The contact 6 is thus closed and the alarm device is in the operative condition, in which an alarm signal is given at a preset time.
  • the clock When the user desires to place the alarm device 4 into inoperative condition, either during production of an alarm signal or to avoid production of an alarm signal, the clock is simply tilted towards the position shown in FIGS. 1 and 2. During tilting, button 5 applies against surface 13 and the weight of the clock causes button 5 to retract against the action of spring 7 and blade 8. When the clock comes to rest an surface 3, blade 8 is raised and contact 6 is open so that the alarm device is in the operative condition.
  • the described alarm clock is extremely practical since the tilting movement required for placing the alarm device in the operative or inoperative condition can be achieved very easily. Moreover, a simple observation of the position of the clock is sufficient to indicate whether or not the alarm device is set to operate.
  • the button 5 could bereplaced by a gravity operated contactor disposed inside case 1, for example a miniature contactor having a drop of mercury which is displaced when the clock is tilted between the described positions.
  • case 1 could be pivotally mounted on a support plate about an axis along the line of intersection of surfaces 2 and 3. Magnetic or other means could then be provided for firmly holding the clock in one or both of the previewed positions, instead of relying upon a particular location of the center of gravity of the clock. 7
  • an alarm clock means when enabled for generating an alarm signal at a preselected time; and means for enabling and disenabling the alarm signal generating means and for simultaneously indicating the enabled and disenabled status thereof comprising a clock housing having two discrete planar surfaces at oblique angles with one another and each surface defining a stable rest position for the clock and said clock housing positionable on one of said planar surfaces to thereby enable said alarm signal generating means and indicate the enabled status by one orientation of said clock housing and positionable on the other of said planar
  • said means for enabling and disenabling includes a switch having a pushbutton projecting from said other planar surface when said clock housing is positioned on said one planar surface and movable to a position wherein the pushbutton is flush with said other planar surface when said clock housing is positioned on said other planar surface.
  • said means for enabling and disenabling includes a gravity actuated switch.
