Definitions

  • This invention relates to alarm clocks and, more particularly, to an illuminating indicating mechanism for visually indicating whether the clock alarm mechanism has been set.
  • Another object of my invention is to provide such an indicating arrangement which is easily operated, stable in its alignment, and long lasting.
  • an alarm clock having a dial with a small portion adapted to permit the passage of light therethrough is provided with an improved alarm-set indicating arrangement.
  • a shutter-lever having an elongated body portion including an elongated passage, is inserted over one of the clock mounting studs with a close sliding fit.
  • the body portion also includes a cam surface to be engaged by the clock alarm shut-off lever and an arm extending from the body opposite the cam surface.
  • a shutter is mounted on the arm for movement between the small dial portion and the light source to block the passage of light.
  • a spring is provided which biases the body portion of the shutterlever against one of the clock mounting plates so that the shutter is always in proper alignment with the small dial portion and biases the shutter-lever to its light-passing position.
  • the alarm shut-cit lever engages the cam surface as the shut-off lever is moved to the alarm-oif position to pivot the shutter-lever and move the shutter to a light-blocking position.
  • the shutoif lever is moved to the alarm-set position, it is disengaged from the cam surface and the spring pivots the shutter-lever in the opposite direction to move the shutter to a light-passing position.
  • FIG. 1 is a front elevational view, partly broken away, of an alarm clock incorporating the alarm-set indicating arrangement of my invention, showing the shutter and shutter-lever mechanism in its two positions;
  • FIG. 2 is a plan view of a portion of the internal structure of the alarm clock of FIG. 1, showing the alarm-set indicating arrangement in the alarm-set position;
  • FIG. 3 is a plan view similar to FIG. 2, showing the alarm-set indicating arrangement in the alarm-off position;
  • FIG. 4 is a partial side elevational view of a portion of the internal structure of the alarm clock of FIG. 1, showing the alarm-set indicating arrangement in the alarm-set position;
  • FIG. 5 is an enlarged perspective view of the shutter and shutter-lever mechanism of my invention.
  • the clock includes a casing which encloses the other members of the clock.
  • a translucent dial 11 mounted in the front of the casing is a translucent dial 11 backed by an opaque mask 12 and a lens 13, which is spaced back of the mask.
  • the lens is lighted by a source of illumination 14 positioned adjacent one edge of the lens.
  • the source of illumination includes a lamp holder 15 containing and supporting a lamp 115. The holder 15 directs the light emitted by lamp .16 toward the lens 13.
  • the clock also includes a first mounting plate 17 and a second mounting plate 18, which support various operative elements of the clock.
  • the plates 17 and 18 are maintained in spaced relationship by a number of studs including that indicated at 19.
  • Another stud 20 is mounted on and extends beyond plate 18 to support a shutter and shutter-lever mechanism.
  • the clock is provided with a slidably mounted, manually operated alarm shut-eff lever 21, which is disposed in a horizontal position for movement toward and from the dial 11.
  • the shut-off lever includes a cam surface 22 which is positioned to control the movement of an alarm vibrator 23, which may be of the resilient, magneticallyoperated type. When not restrained by the cam surface 22, the vibrator 23 vibrates to produce an audible alarm.
  • the alarm shut-off lever 21 includes a pair of forwardly extending arms 24 and 25, with arm 25 being bent out of the plane of the lever 21 so as to provide a surface 26 for pivoting the shutter and shutter-lever mechanism generally indicated at 27.
  • Suitable indicia may be located on the central or face portion of the translucent dial 11 so as to be readily seen by an observer.
  • the border portion of the dial, surrounding the clock face, is completely backed by the mask 12 except for a small hole 23.
  • the lens 13 is formed from any suitable material such as glass or plastic normally employed for edge lighted applications, and is provided with suitable reflective surfaces which direct light forwardly from the source of illumination. With this dial arrangement the entire dial face is easily observed during the daytime; however, at night only a portion of the dial is illuminated because of the shielding eifect of the opaque mask 12. This arrangement provides a dial of sutlicient size for daytime use and nighttime use while keeping the lighted area to a minimum during the nighttime.
  • an alarm-set indicating arrangement is provided to visually indicate whether the clock alarm is in the of. position or the set position.
  • 12 is formed with a small provided with an additional reflective surface, such as beveled edge 29, which is aligned with the hole 28 so that light traveling edgewise through the lens and striking the beveled edge 29 will be reflected forwardly through the hole 28 and appear as hole 28 and the lens 13 is a light spot on the dial 11. This spot will be clearly visible when the clock is in a darkened surrounding.
  • the mechanism includes a uniquely shaped shutter-lever 36 having an elongated, tubular body portion 31.
  • the body portion 31 includes an elongated passage 32 for insertion over the stud with a close sliding lit.
  • the close sliding fit of the stud within the passage ensures that the axis of the body portion remains perpendicular to mounting plate 17.
  • the body portion is provided with a cam surface 33'which is disposed for engagement by surface 25 of arm 25 as the shut-ofl lever 21 is moved toward dial ii.
  • an arm 34 extends outwardly from body portion 31 oppositely of cam surface 33 and is provided with an ear 35 which is generally parallel to the axis of body portion 31.
  • a thin shutter 36 is mounted on the ear 35.
  • the shutter is generally L-shaped, having a mounting portion 37 for'connection to ear 3S and a light-blocking portion 38 which is generally parallel to arm 34.
  • the body portion 31 of shutter-lever 3% is provided with a hole 39 and one end of a spring 44 is received through the hole 39.
  • the other end of the spring 4t) is bent around mounting plate 18.
  • the entire structure could be made of metal; however, this would result in a relatively heavy and costly construction.
  • the entire structure could be made of molded plastic, including mounting the shutter on the shutter-lever by molding the two as a single element.
  • the light-blocking portion of the shutter should be thin to give the best results and a thin plastic element would be easily deformed or broken. I have found that the most satisfactory structure is a molded plastic shutterlever 39 and a thin metal shutter 36, mounted on the shutter-lever.
