Abstract
An object of the present invention is to provide a speedometer capable of distinctly indicating traveling speeds in a range of traveling speeds at which a vehicle travels in most of the time. A speedometer has a scale plate provided with a main speed scale of a substantially semicircular shape. The overall scale range of the main speed scale is divided by division points into four equal sections, and scale marks 5, 10, 15 and 45 mph are marked on the main speed scale at the division points, respectively. A low-speed range, i.e., a working speed range, of 0 to 15 mph extends in 3/4 of the overall scale range and the working speed range is graduated in quinary divisions of 5 mph. Therefore, speed indications in the low-speed range can accurately be read with an increase number of digits.
Claims18
A speedometer for a vehicle comprising:
- a scale plate extending an overall predetermined distance from a low-speed scale range including a first traveling speed and a second traveling speed to a high-speed scale range including a third traveling speed;
- an indicator operatively mounted for moving relative to said scale plate for indicating a speed of a vehicle;
- said low-speed scale being graduated by scale markings in divisions being spaced apart a greater distance relative to scale markings for graduating the high-speed scale range;
- said first traveling speed of the low-speed scale range extending from zero to a distance equal to approximately one quarter of the overall predetermined distance of the scale range from the low-speed range to the high-speed range over which said indicator moves, said second traveling speed of the low-speed scale range extending a distance from approximately the one quarter of the overall predetermined distance of the scale range from the low speed range to approximately three quarters of the overall predetermined distance of the scale range over which said indicator moves for providing an enlarged low-speed scale range corresponding to low working speeds of a vehicle, and said third traveling speed of the scale range being positioned to extend a distance from approximately the three quarters position to a four quarters position of the scale range for indicating a high-speed range, said low-speed range enabling clear visibility to permit operation of the vehicle at a speed regulated in increments of 0.5 mph (0.8 kmph) while operating the vehicle in said low-speed scale range.
A speedometer for a vehicle comprising:
- a speed display extending an overall predetermined distance from a low-speed scale range including a first traveling speed and a second traveling speed to a high-speed scale range including a third traveling speed;
- an indicator operatively mounted for moving relative to said speed display for indicating a speed of a vehicle;
- low-speed scale markings on said low-speed scale range being graduated and being spaced apart a greater distance relative to high-speed scale markings for graduating the high-speed scale range;
- said first traveling speed of the low-speed scale range extending from zero to a distance equal to approximately one quarter of the overall predetermined distance of the scale range from the low-speed scale range to the high-speed scale range over which said indicator moves, said second traveling speed of the low-speed scale range extending a distance from approximately the one quarter of the overall Predetermined distance of the scale range from the low speed range to approximately three quarters of the overall predetermined distance of the scale range over which said indicator moves for providing an enlarged low-speed scale range corresponding to low working speeds of a vehicle, and said third traveling speed of the scale range being positioned to extend a distance from approximately the three quarters position to a four quarters position of the scale range for indicating a high-speed range, said low-speed range enabling clear visibility to permit operation of the vehicle at a speed regulated in increments of 0.5 mph (0.8 kmph) while operating the vehicle in said low-speed scale range.
