The Portable Stick-on Bubble Level
This web page contains information related to US Provisional Patent Application(PPA) #61493222, filed 060311, titled Portable Stick-On Bubble Level.
Detailed Description (Diagrams Below)
A miniature (approx. one to two inches) hemispherical, plastic, portable bubble level
having encircling latitudinal angle markings, and further having a sticky back hook and
loop connection with whatever tool or other device, e.g. a vehicle dashboard, or other
construct requiring a determination of angular positioning, upon which it is placed.
The circular base of the level would have two downwardly extended mounting portions
with permanently mounted hook (or loop) material for reaching around curves or other
obstructions, for example, on the curved back portion of an electric drill or on top of a
reciprocating saw. In use, the opposing hook or loop sticky back material would be
positioned at an appropriate place on the tool where the portable bubble level is to be
mounted. The purpose of the portable bubble level is to allow the tool user to easily
determine when the tool is level or otherwise positioned at a desired angle.
For ease of bubble sighting, the internal liquid medium would be color dyed rather
than clear. A plurality of opposing hook (or loop) mounting strips would be provided
with the portable level so that it might be easily mounted and utilized with a variety
of tools as needed. A user would then mount two of the strips for each desired position
on a particular tool to accommodate the two mounting protrusions on the bubble level.
To my knowledge there are currently no inexpensive, miniature portable level attachments
for a drill, saw, or other power tool on the market. The device is innovative because it can
be quickly and easily exchanged between numerous tools, and because it allows for a
rapid determination of angles other than just vertical or horizontal. Additionally, as noted
above, since the device is portable, it can used wherever a determination of current
angular positioning is required. Although some power hand tools are manufactured
with electronic or bubble levels, the majority of them are not so made. Power hand tools
would all be far more accurately used tools if they respectively had small hemispherical
bubble levelers with circular angle markings on all sides so that a tool user could
determine at a glance if the tool was level or at the required angle for drilling, sawing, etc.
The proposed device offers a quick, easy and inexpensive solution to this problem and to
the issues of leveling in general.
