Abstract
An adjustable timer teaches time in a simple manner to those having difficulty understanding the concept of time. The timer displays remaining and elapsed time. The timer may be set to rotate a shaft at different speeds. A colored disk is attached to the shaft. Boards having faces with different numerical indicia reside in a cavity and may be interchanged by a user. The exposed board face corresponds to the setting of the timer such that one full rotation of the shaft and disk corresponds to the numerical indicia of the exposed board face.
Claims20
An apparatus for displaying remaining and elapsed time comprising:
- a generally rectangular body comprising a generally rectangular front tray and a generally rectangular rear tray secured to the generally rectangular front tray, the generally rectangular front tray having a circular recess, the generally rectangular body having a battery compartment for storing at least one battery;
- a control module located between the generally rectangular front and rear trays of the generally rectangular body, the control module being powered by said at least one battery and including a shaft which rotates at different rates, one of the rates of rotation of the shaft being determined by a user setting a knob connected to the control module,
- a colored disk located in the recess of the generally rectangular front tray and secured to the shaft such that the colored disk rotates with the shaft;
- a stationary background disk located in the recess of the generally rectangular front tray in front of the colored disk, the stationary background disk having a slit through which a portion of the colored disk passes such that upon rotation of the shaft a portion of the colored disk rotates in front of the stationary background disk;
- a circular lens located in front of the stationary background disk and secured to the generally rectangular front tray;
- removable boards secured in a cavity in the generally rectangular front tray of the generally rectangular body, each of the boards having a circular opening through which the circular lens passes;
- and
- a positioner secured to the shaft in front of the circular lens for manually setting the position of the rotatable colored disk.

An apparatus for displaying remaining and elapsed time comprising:
- a body comprising a front tray and a rear tray secured to the front tray, the front tray having a circular recess;
- a control module and at least one battery located between the front and rear trays of the body, the control module being powered by said at least one battery and including a shaft which rotates at different rates, one of the rates of rotation of the shaft being set by a knob connected to the control module,
- a colored disk located in the recess of the front tray and secured to the shaft such that the colored disk rotates with the shaft;
- a stationary background disk located in front of the rotatable colored disk, the stationary background disk having a slit through which a portion of the rotatable colored disk passes upon rotation of the shaft and the rotatable colored disk;
- removable boards secured in a cavity in the front tray of the body, each of the boards having numerical indicia on at least one face of the board to indicate different time periods, each of the time periods corresponding to one of the rates of rotation of the shaft;
- and
- a positioner secured to the shaft to enable a person to manually position the rotatable colored disk.
4 more elements
An apparatus for displaying remaining and elapsed time comprising:
- a body comprising a front tray and a rear tray secured together,
- the body having a battery compartment for storing at least one battery, said at least one battery powering a control module located in the body, the control module determining one of multiple speeds at which a shaft rotates to rotate a colored disk secured to the shaft to indicate elapsed and remaining time;
- removable boards secured in a cavity in the front tray of the body with at least one biasing member, at least one of the boards having numerical indicia marks on at least one face of the board to indicate different time periods, each of the time periods corresponding to one of the speeds of rotation of the shaft;
- and
- a lens, each of the boards having an opening through which the lens passes.
