Spirit level

A spirit level for setting a vertical surface, the spirit level having a longitudinal level axis and comprising:

• (a) a main body having a leveling surface to be set on the vertical surface and defining an imaginary longitudinal plane traversing the longitudinal level axis and perpendicular to said leveling surface;
• (b) a bubble vial having a longitudinal bubble vial axis disposed in said imaginary longitudinal plane for providing a visual indication of an inclination of the vertical surface with respect to the vertical;
• and
• (c) a reflective surface inclined with respect to said longitudinal bubble vial axis for enabling a user standing directly opposite the spirit level to view a reflected image of said bubble vial along a direct opposite line of sight bound within a direct opposite angular viewing range with respect to said imaginary longitudinal plane;
• characterized in
• said reflective surface having a pivot axis disposed in said imaginary longitudinal plane and subtending an acute included angle with said longitudinal bubble vial axis whereby said reflective surface is pivotal with respect to a non-pivoted direct opposite viewing position enabling a user standing directly opposite the spirit level to view a reflected image of said bubble vial along said direct opposite line of sight bound within said direct opposite angular viewing range,
• said reflective surface being pivotal between an extreme clockwise viewing position and an extreme counterclockwise viewing position with respect to said non-pivoted direct opposite viewing position thereby enabling a user standing offset either to the left and the right of the spirit level to pivot said reflective surface toward himself to view a reflected image of said bubble vial such that the spirit level affords an overall angular viewing range greater than said direct opposite angular viewing range.
