Abstract

"MARTELO E CABEçA DE MARTELO QUE TEM UM EXTRATOR FRONTAL E MéTODO DE EXTRAçãO DE PREGO DE UMA SUPERFìCIE". Trata-se de um martelo (10) e uma cabeça de martelo (12) que compreende uma cabeça golpeadora (20) com uma superfície golpeadora (22) na mesma que define uma parte dianteira do martelo (10), e uma seção de interface que inclui pelo menos um extrator frontal (32). Em uma realização, é empregada uma pluralidade de extratores frontais (32, 34, 36), os quais são formados por um entalhe (33, 35, 37) e a seção de interface inclui um sulco que se estende através dos extratores frontais (32, 34, 36) . Em uma realização, o entalhe é dimensionado e/ou magnetizado para permitir que uma cabeça de um prego seja suportada no mesmo de modo que o prego fique suspenso substancialmente perpendicular em relação à superfície golpeadora. Um método de extração de um prego de uma superfície também é apresentado.
