Manual propulsion engine i.e. oar, for small floating boats, has tubular shank including threaded end screwed in cavity, where left right linear movement is stimulated at shank by user for actuating blade in order to propel floating boat

摘要

#CMT# #/CMT# The engine has a flexible blade (1) made of molded flexible material and extended through a rigid cylinder (2) terminated by a tapped cavity (3). A tubular shank (5) closed at two ends and includes a threaded end (4) screwed in the cavity. A left right linear movement is stimulated at the shank by a user for actuating the blade in order to propel a floating boat. The blade adopts a shape of a fish tail. #CMT#USE : #/CMT# Engine i.e. oar, for manual propulsion of small floating boats. #CMT#ADVANTAGE : #/CMT# The engine permits manual rear propulsion of the small floating boats by the user without any previous knowledge. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded view of a manual propulsion engine. 1 : Flexible blade 2 : Rigid cylinder 3 : Tapped cavity 4 : Threaded end 5 : Tubular shank.
