UNIVERSAL TAPE

METRE A RUBAN UNIVERSEL

English Abstract

A universal tape including a housing formed with a
downward extending cylindrical hole on a lateral side. A
lower end of the cylindrical hole is disposed with a pen
tip opening. An inner wall of the cylindrical hole is
disposed with intersecting cross lines which outward
extend to define a cut right angle. The tape is marked
with scales such as metric system scale, scale and other
scales. The tape is further formed with a circle center
hole. The universal tape has the functions of drafting a
circle, measuring whether an article is vertical and
measuring the horizontal distance between two points on
different levels.

French Abstract

Le mètre à ruban universel comprenant un boîtier formé d'un trou cylindrique s'étendant vers le bas sur un côté latéral. La partie inférieure du trou cylindrique est munie d'une ouverture en bout de porte-plume. Une paroi intérieure du trou cylindrique est munie de lignes croisées de réticule qui s'étendent à l'extérieur pour définir un angle droit. Le ruban possède des échelles comme le système métrique, le système impérial(?) et autres. Il est en outre muni d'un trou central circulaire. Le mètre à ruban universel permet de tracer des cercles, de déterminer si un objet est vertical et de mesurer la distance horizontale entre deux points placés à des niveaux différents.

A UNIVEKS~L TAPe

BACKGROUND OF THE INVE~TION
The present invention relates to a universal taPe has
the functions of drafting a circle, measuring whether an
article is vertical and measuring the horizontal distance
between two points on different levels.
An existing tape can only measure the horizontal
distance between two points on the same level. When it is
desired to measure the horizontal distance between two
Points on different leYels, conventional 1Y the tape is
Pulled out and then a plumb line tYing a Plumb is used to
locate a vertical point for measuring the horizontal
distance. Such Procedure is quite troublesome and
inaccurate. Moreover, with the conventional tape, a user
cannot draft a circle. This causes inconvenience in use.
SUMMARY ~F THE INYENTI~N
It is therefore a primarY obiect of the present
invention to Provide a universal tape ~hich can be
convenientlY used to accurately draft a circle. measure
whether an art;cle is vertical and measure the horizontal
distance between two Points on different levels.
According to the above obiect, the universal tape of
the present invention includes a housing having two
Parallel sYmmetrical walls. One lateral side of the

2189419


housing is formed with a downward extending cYlindrical
hole. A lower end of the cYlindrical hole is disPosed vith
a Pen tiP oPening. An inner wall of the cYlindrical hole
is disPosed with intersecting ~ross lines which outward
extend to define a cut right angle. The tape is marked
with scales such as metric sYstem scale. scale and other
scales. The tape is further for~ed with a circle center
hole for drafting a circle.
A level bubble is disposed beside the cylindrical
hole, wherebY the cut right angle and the le~el bubble are
used to measure whether an article is vertical. In
addition, the cYlindrical hole and the level bubble are
used to measure the horizontal distance between two Points
on different levels. The cross lines are disposed on the
inner wall of the cYlindrical hole in a dented or
projecting pattern.
The Present invention can be best understood through
the following description and accomPanYing drawings.
wherein:

DETAILED DESCRIPTION OF THE PR~FERRE~ E~B~DIMENT
Please refer to Figs. 1 and 2. The universal taPe of
the Present invention includes a housing 10 having two
Parallel symmetrical walls. ~ne lateral side of the
housing 10 is formed with a downward extending cylindrical
hole 11. The lower end of the cylindrical hole 11 is
disposed with a Pen tiP oPening 12. The inner wall of the
cylindrical hole 11 is disPosed with intersecting cross
lines 13 which o~tward extend to define a cut right angle
14.
Referring to Fig. 3, the taPe 20 is oarked with
scales 21 such as metric sYstem scale. scale and other
scales. The scale includes 1i200, 1/400 and 1/500 scale.
In addition, the taPe 20 is formed with a circle center
hole 22.
A level bubble 15 is disposed beside the cylindrical
hole 11. The cut right angle 14 and the level bubble 15
serve to measure whether an article is vertical. The
cYlindrical hole 11 and the level bubble 15 serve to
measure the horizontal distance between two points on
different levels. The cross lines 13 are disPosed on the
inner wall of the cylindrical hole 11 in a dented or
projecting pattern.
The Present invention improves the shortcoming of

- 2189~19


insufficiency of function of the conventional tape. In
addition, the Present invention is able to (1~ draft a
circle, (2) measure whether an article is vertical and (3~
neasure the horizontal distance between two Points on
different levels. The functions of the present invention
are described as follows:
~ 1) With the circle center hole 22 serving as the
circle center, the distance between the circle center and
the front hook 17 of the tape is equal to the distance
between the front end 16 of the tape and the pen tip
opening 12. Therefore. the radius of the circle is iust
the scale seen at the front end 16 of the taPe. A nail is
fixed in the circle hole 22 and a Pen is inserted into the
cylindrical hole 11 to draft a circle with desired radius.
t2~ The cut right angle 14 is attached to the article
to be ~easured and the level bubble 15 is observed to see
whether the level bubble 15 is in the horizontal position
so as to measure whether the article is vertical.
t3) When measuring the horizontal distance between
two Points on different levels. the taPe 20 is pulled out
with the front hook 17 fixed at the higher point. Then the
tape 20 is pulled to the uPPer side of the lower point.
Then the lower point is downward seen from the cross lines
13 in the cYlindrical hole 11 to observe whether the level
bubble 15 is in the horizontal Position. If so, the sum of

~ 218g4ig


the scale shown on the tape 20 and the distance from the
front end 16 of the tape to the pen tiP oPening 12 is iust
the horizontal distance between the two Points on
different levels.
It should be noted that the above descriPtion and
accompanying drawings are onlY used to illustrate one
embodiment of the Present inYention, not intended to limit
the scoPe thereof. Any modification of the embodiment
should fall within the scope of the present invention.
