Abstract:
A blade scraping tool, said tool comprising:a hand gripping casing having a front end and a rear end, said casing being formed of a top covering and a bottom covering connected to each other, said top and bottom coverings together defining an opening at the front end of the casing, said casing further including a slot extending centrally and longitudinally on the top covering, said slot having front aid rear extremities; peripheral elastomer rim mounted along a portion of a periphery of the casing formed by the top and bottom coverings; a resilient plate mounted inside the hand gripping casing, said plate being slidably movable along said casing and comprising a push button extending outwardly from the casing through the slot and being slidably movable therealong; a blade; blade mounting means on which the blade is mounted, said blade mounting means being affixed to a front end of the resilient plate and being positioned and devised to slide through the opening of the casing; interlocking means cooperating with the resilient plate and the top covering for locking the plate and the blade into a retracted position where the blade is entirely encased within the casing, said interlocking means further cooperating with the resilient plate and the top covering for locking the plate and the blade into an operating position where the blade is exposed through the opening of the casing for operation of the tool; wherein the retracted position is attained by actuating the push button onto a first position along the slot corresponding to the retracted position; wherein the operating position is attained by actuating the push button onto a second position along the slot corresponding to the operating position, the second position being closer to the front end of the casing than the first position; and wherein a blade release position is attained by actuating the push button onto a third position along the slot, said third position being closer to the front end of the casing than the second position and allowing mounting and removal of the blade to and from the blade mounting means.
