Abstract
A teaching device for teaching students different scales of
measure and aiding in the taking of accurate measurements by users
of the device includes a first face that is marked with standard
units of measure such as feet, inches, and fractions of inches.
Each scale represents a different unit of measure scale and is
arranged next to smaller scale in an order such that the feet
measurement is arranged next to the inch scale. The inch measure is
also arranged to the half-inch scale which is arranged next to the
quarter inch scale. This continues such that each succeeding scale
is arranged between a larger and smaller scale. A second face is
marked with scales representing metric units of measurement. Each
scale on the second face represents a unit of measurement on one
order of magnitude smaller than the preceding scale.

Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a device for teaching the
use of scales that represent various units of measure and for
easily measuring a distance between two points. The units of
measure may include either standard or metric units. The standard
units of measure may comprise feet, inches, and fractions of
inches. The metric units of measure may include meters measured in
hundredths, thousandths and ten thousandths of meters. More
specifically, the invention relates to a device having standard
units of measure represented on one side thereof and metric units
represented on an opposite side thereof.
[0002] Known types of rulers exist that include a face having an
upper edge marked with inches and fractions thereof. A lower edge
of the face is marked with millimeters and centimeters.
[0003] Another type of ruler comprises three sides for use in
aiding a draftsman. Various faces of the three sides are marked
with different units or scales. The draftsman rotates the ruler to
a desired unit of measurement to measure a distance of a line or
between two points.
[0004] Neither of the aforementioned rulers provides various scales
that are labeled and clearly show a relationship of the various
standard scales to one another along with the various metric scales
to one another.
BRIEF SUMMARY OF THE INVENTION
[0005] The instant invention is a ruler-type device that is
approximately twelve and one-half inches long. The device is
approximately one and one-half inches wide and one-eighth of an
inch thick. It may comprise wood, plastic, metal, fabric, paper,
rubber or any other material on which a scale can be permanently
marked.
[0006] The device includes a first side that comprises two vertical
lines. Each vertical line is spaced approximately one-quarter of an
inch from each edge of the ruler. Five horizontal lines are placed
on the ruler are spaced one-quarter of an inch apart. The first
line is arranged approximately one-quarter of an inch from the top
of the device.
[0007] In one embodiment, the device includes a side having a list
of measurements that are vertically represented in an ascending or
descending order. The standard measurement side of the device is
labeled with the following abbreviations: ft. corresponding to
feet; in. corresponding to inches; 1/2 in. corresponding to
half-inches; 1/4 in. corresponding to quarter-inches; 1/8 in.
corresponding to one-eighth inches; and, 1/16 in. corresponding to
one-sixteenth of inches. These markings are provided between the
vertical lines and the edges of the device. There are provided one
hundred and ninety-two marks on the 1/16 inch scale. There are
provided ninety-six marks on the 1/8 inch scale. Forty-eight marks
are provided on the 1/4 inch scale. Twenty-four marks are provided
on the one half inch scale. A one foot mark is provided on the ft.
scale. Each scale is a different color.
[0008] In one embodiment, the device includes a series of metric
scales arranged in an ascending or descending order. A vertical
line is provided approximately three-eighths of an inch from the
left side. A second vertical line is provided approximately
three-eights of an inch from the right side. Four horizontal lines
are placed one-quarter inch apart from one another and span the
distance between the vertical lines. A series of notations are
provided between the vertical line nearest the left side and the
left side and the vertical line nearest the right side and the
right side. The following marks are provided "mm", "1/2 cm", "cm",
and "dm". The "mm" represents millimeters. The "1/2 cm" mark
represents half-centimeters. The "cm" represents centimeters. The
"dm" represents decimeters. There are provided three hundred marks
on the millimeter scale. There are provided sixty 1/2 centimeters.
Thirty marks are provided across the centimeter scale. Ten marks
are provided across the decimeter scale. Each scale is a different
color.
[0009] It is an object of the invention to provide a teaching and
measuring device that increases the ability of an individual to
identify and precisely measure objects to at least a sixteenth of
an inch when using a standard scale provided on the device.
[0010] It is another object of the invention to provide a teaching
and measuring device that increases the ability of an individual to
identify and precisely measure objects to at least a millimeter
when using the metric scale provided on the device.
[0011] It is an object of the invention to provide a teaching
device that includes a face having standard markings to denote a
foot, inches, and fractions thereof. The fractions of inches may
include half-inches, quarter-inches, eighth-inches,
sixteenth-inches and thirty-seconds of an inch. Each scale is
arranged next to a larger scale on one side and a smaller scale on
the other side. Thus, the scales proceed from a foot measurement to
an inch measurement and fractions of inches. In this manner the
scales are measured in an ascending or descending order.
[0012] It is another object of the invention is to provide a
teaching device having a face that includes metric scales including
decimeters, centimeters, one-half centimeters and millimeters.
Similarly, the scales that represent the metric measurements are
arranged in either an ascending or descending order.
[0013] It is still another object of the invention to provide a
teaching device that includes both standard and metric measurement
scales on a single face of a ruler type device.
[0014] It is a further object of the invention to provide a clear,
see-through device that comprises a ruler-type teaching device that
includes a face having standard markings to denote a foot, inches,
and fractions thereof. The fractions of inches may include
half-inches, quarter-inches, eighth-inches, sixteenth-inches and
thirty-seconds of an inch. Each scale is arranged next to a larger
scale on one side and a smaller scale on the other side. Thus, the
scales proceed from a foot measurement to an inch measurement and
fractions of inches. In this manner the scales are measured in an
ascending or descending order.
[0015] It is another object of the invention to provide a clear,
see-through device that comprises a ruler-type teaching device that
includes a face having metric scales including decimeters,
centimeters, one-half centimeters and millimeters. Similarly, the
scales that represent the metric measurements are arranged in
either an ascending or descending order.
[0016] It is another object of the invention to provide a measuring
device that includes different scales having different colors for
easily discerning between the scales.
[0017] It is another object of the invention to provide a measuring
and teaching device that visually represents equivalents of
different denominations of scales.
[0018] Further objects, features and advantages of the invention
will become apparent from a consideration of the following
description and the included claims when taken in connection with
the previous discussion and the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0019] FIG. 1 is a view representing one side of the teaching
device.
[0020] FIG. 2 is a view representing another side of the teaching
device.
[0021] FIG. 3A is a prior art ruler.
DETAILED DESCRIPTION OF THE INVENTION
[0022] FIG. 1 shows a first side 10 of the device 1. The device
comprises a top 2 and a bottom 4. The first side 10 includes
several scales. Nearest bottom 4 is a millimeter scale 9. Provided
above mm scale 9 is 1/2 cm scale 7. A cm scale 5 is arranged above
1/2 cm and below decimeter scale 3. As can be clearly seen, a user
of the device 1 can easily recognize the relationship of the scales
to one another. A vertical line 40 is provided at either side of
the device.
[0023] FIG. 2 is a second side 20 of the device 1. The second side
of the device represents standard measurement scales. A 1/16 inch
scale 21 is located nearest the bottom 4. A 1/8 inch scale 19 is
arranged above the 1/16 inch scale 21 and below the 1/4 inch scale
17. A 1/2 inch scale 15 is arranged below inch scale 13, which is
in turn arranged above the foot scale 20. As can be realized, the
scales are arranged such that there are twice as many lines as the
scale arranged above it. This allows a user to quickly recognize
the relationship between the various scales.
[0024] FIG. 3 is a prior art type of ruler that comprises both
metric and standard scales provided on one side thereof. The metric
and standard scales are provided on separate scales. However, the
standard scales show only inches and fractions thereof mixed
together in a single scale. This is very confusing for one who is
learning to read a ruler. Moreover, it is very difficult to
recognize the relationship of one standard scale to another.
[0025] It is to be understood that the invention is not limited to
the exact construction illustrated and described above. Various
changes and modifications may be made without departing from the
spirit and the scope of the invention as defined in the following
claims.
