Abstract
Measurement devices for measuring and marking purposes and including an integral angle finder for enabling two modes of use: placing either major body surface on a flat surface or setting a base on an inclined surface for indicating its inclination. Spirit levels for setting a spaced apart pair of adjacent upright studs of more than one standard stud width at a standard stud separation between the midpoints of spaced apart pair or upright studs. Caster device pair for use with a ladder having a stabilizer for enabling wheeling the ladder while being held generally horizontal by a user for assisting moving the ladder without having to lift its entire weight.
Claims12
A measurement device comprising:
- (a) a base with a base setting surface for placing on a generally horizontal flat surface and a base top surface opposite said base setting surface, said base top surface having a central longitudinal centerline;
- (b) a generally planar body mounted on said central longitudinal centerline such that said body stands upright on said base placed on a generally horizontal flat surface,
- said body having a first major body surface and a second major body surface, at least one of said first major body surface and said second major body surface having measurement markings,
- said body having an angle finder aperture between said first major body surface and said second major body surface;
- and
- (c) an angle finder mounted in said angle finder aperture,
- said angle finder including an angle finder housing and a bubble vial rotatably mounted in said angle finder housing,
- said angle finder housing having a first major angle finder housing surface parallel with said first major body surface and a second major angle finder housing surface parallel with said second major body surface,
- at least one of said first major angle finder housing surface and said second major angle finder housing surface have angular markings for indicating an angle of an inclined surface on setting said base setting surface thereon,
- wherein said base has a thickness T1, said body has a thickness T2 and said angle finder has a thickness T3 in a side elevation view of the measurement device facing said thicknesses,
- wherein T1>T3>T2 and said angle finder being slidingly mounted in said angle finder aperture in a transverse direction with respect to said central longitudinal centerline such that, in use, placing said first major body surface on a flat surface causes said second major angle finder surface to protrude from said second major body surface and placing said second major body surface on a flat surface causes said first major angle finder surface to protrude from said first major body surface.
