back to regular rulers for measurements and learning tool at
school. When brackets are erected up, they are tall enough to
support the books from both sides. The two rulers can be
combined together by making “ ” shaped equal-size
grooves on one side of the rulers. This way, the two rulers
can combine together inserting their grooves oppositely to
each other like a puzzle. Having many grooves can expand

Title Ruler Having a Clip Holder for Writing Tools
Authors SONG, SION
Institution Dae Myeong Middle School, Korea
Patent no. 10-0015835
Description
On the surface of a plastic 30cm-ruler, L-shaped clip holder
is installed where a pencil can be inserted on the clip
holder’s diagonal groove. When the pencil inserted to the
diagonal groove and rotated laterally, it mounts to the clip
holder in which the silicon bump prevents the pencil from
falling out or being broken. This is an idea applied to a ruler
which the clip holder attached on the surface serves as
pen/pencil holder.
The key feature is that because a ruler that is being used for
measurement, drafting, drawing, etc always require a pencil
or a pen. By installing a clip holder on the ruler surface, the
pencil/pen can be inserted into the holder in which the elastic
silicon bump of the clip holder grips the writing tool from
falling out.
Because the 30cm-ruler can have a pencil or a pen clipped on
top of the ruler surface, the user will never lose his writing
tool while working or studying, but contributing effectively
