Abstract:
A bicycle stem clamp for carrying a bicycle handlebar and providing a releasable connection to a steerer tube, comprising:a first helically twisted clamping member having a first end opposite a second end and separated therefrom by a selected length, said first end being disposed parallel to a first member first plane and having a first substantially semi-cylindrical groove therein with an axis parallel to said first member first plane, said second end being disposed parallel to a first member second plane disposed substantially perpendicularly to said first member first plane and having a second substantially semi-cylindrical groove therein with an axis parallel to said first member second plane; a second helically twisted clamping member having a first end opposite a second end and separated therefrom by said selected length, said first end being disposed parallel to a second member first plane and having a first substantially semi-cylindrical groove therein with an axis parallel to said second member first plane, said second end being disposed parallel to a second member second plane disposed substantially perpendicularly to said second member first plane and having a second substantially semi-cylindrical groove therein with an axis parallel to said second member second plane; wherein said first and second helically twisted clamping members are juxtaposed with said first helically twisted clamping member first end abutting said second helically twisted clamping member first end and with said first helically twisted clamping member second end abutting said second helically twisted clamping member second end, to make said first member first plane and said second member first plane substantially coplanar while said first member second plane and said second member second plane are substantially coplanar; and said substantially semi-cylindrical grooves being aligned to define first and second cylindrical apertures therethrough, said first aperture being transverse to said second aperture and being sized to receive the handlebar and said second aperture being sized to receive the steerer tube.
