<p>#CMT# #/CMT# The device has a locking and unlocking bush (7) co-operated with an adjusting nut (3) using a locking system that locks the bush on the adjusting nut when the bush is supported on a support washer (6). The locking system has two projections (73) that are engaged with a groove (31) formed at the periphery of the adjusting nut. A compression spring (8) is arranged in an enclosure (72) that encloses the adjusting nut, for being supported on an outer surface (30) of the adjusting nut and an end wall (71) of the bush. #CMT#USE : #/CMT# Device for rapid assembling and disassembling of a wheel axle (claimed) i.e. front wheel axle, of a cycle i.e. bicycle, during cycling. #CMT#ADVANTAGE : #/CMT# The adjusting nut permits rapid assembling and disassembling of the front wheel axle of the bicycle, in a simple, reliable and safe manner. The configuration of the device permits conservation of safety pins, while ensuring rapidity in changing of the front wheel by a rider and avoiding any tearing risk of the wheel, thus preventing dangerous or undesired fall of the rider from the bicycle, during cycling. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a safety nut. 3 : Adjusting nut 6 : Support washer 7 : Locking and unlocking bush 8 : Compression spring 30 : Outer surface 31 : Groove 71 : End wall 72 : Enclosure 73 : Projections.</p> |
