Abstract:
An apparatus for extracting a paver stone, and the like from a preset position, including a pair of lifting plates having a body containing one or more lifting aid insertion openings at one end, and at an opposing end, a blade portion having substantially concave tabs with tab edges formed along a pair of slots terminating in one or more of stress relief openings between the body and the blade, wedging a first blade between the paver and a first adjacent paver and wedging a second blade at an opposing end of a paver and a second adjacent paver, substantially compressing the tabs storing spring energy in the blades, pushing the tab edges below the bottom plane of the paver, releasing the stored spring energy thereby substantially decompressing and re-forming the tabs such that the tab edges contact and engage the underside of the paver to be extracted.

Claim (Index 14):
A method for extracting a paver from a preset position, including the steps of:\n (a) wedging a first lifting plate between the paver and a first adjacent paver said first lifting plate having (i) a body portion containing at least one lifting aid insertion opening at one end of the body, and (ii) at an opposing end of the plate, a blade portion having substantially concave tabs with tab edges formed along a pair of slots terminating in one or more stress relief openings between the body and the blade, (b) compressing the tabs and the tab edges thereby storing spring energy in the blade, (c) pushing the tab edges past the bottom plane of the paver, thereby releasing the stored spring energy thereby substantially decompressing and re-forming the tabs, (d) contacting and engaging the tab edges of the first lifting plate with the underside of the paver, (e) wedging at an opposing end of the paver, a second lifting plate between the paver and a second adjacent paver said second lifting plate having (i) a body portion containing at least one lifting aid insertion opening at one end of the body, and (ii) at an opposing end of the plate, a blade portion having substantially concave tabs with tab edges formed along a pair of slots terminating in one or more stress relief openings between the body and the blade, (f) compressing the tabs and tab edges of the second lifting plate thereby storing spring energy in the blade, (g) pushing the tab edges of the second lifting plate past the bottom plane of the paver releasing the stored spring energy thereby substantially decompressing and re-forming the tabs, (h) contacting and engaging the tab edges of the second lifting plate with the underside of the paver, (i) inserting a lifting aid through insertion openings of each of the lifting plates, (j) aligning said insertion openings with a pair of notches joining the lifting plates using the lifting aid, (k) applying an upward force to the lifting aid and transferring such upward force to the lifting plates, (l) extracting the paver.
