A bicycle handlebar stem is provided with a throat which is in open communication with the loop thereof in which the central, knurled portion of a handlebar is received. The width of the throat is sufficiently wide to accommodate the passage of the transverse strut or brace bar disposed in spanning relationship with, and between, the risers of a handlebar while the loop of the stem is advanced along the handlebar riser toward the central, knurled portion thereof.
A bicycle map holder (14) in combination secondary retention device (14) for the stem (20) and handlebar (19) assembly. Such combination resulting in a virtually vibration and windproof, easily viewable, lightweight map holder (14); also providing user with secondary retention (14) means of stem (20) and handlebar (19) assembly in the event of stem (20) failure at binder bolt (17) area. Use of the map holder (14), mandates use of secondary retention feature, thus negating any rider reluctance to use safety equipment and significantly enhancing enjoyment and safety of the sport.
Disclosed is a quickly-adjustable while-in-motion bicycle handlebar securing device which enables a bicyclist to quickly and easily change the bicycle handlebar position while-in-motion to one resulting in less strain upon his neck.
A stem assembly for securing the handlebars of a bicycle to the frame of the bicycle, which stem comprises a barrel and a head, the head being formed from a sheet metal stamping comprising a neck section and a handlebar clamping section. The neck section of the head is of generally annular cross-sectional configuration and is characterized by a longitudinal seam extending for the length of the neck. The seam of the neck section of the head is welded along the seam so as to impart to the stem resistance to torsional failure of the neck.
A handlebar mounting apparatus and method for mounting a handlebar onto a vehicle. The handlebar is mounted to the vehicle such that the handlebar is selectively rotatable about a first axis to allow for adjustment of the axial orientation of the handlebar relative to the vehicle. Additionally, the mounts are connected to the vehicle for selective, eccentric rotation of the mounts about a second axis to allow for selective height and position adjustment of the handlebar in relation to the vehicle. One embodiment provides an apparatus for mounting a handlebar to a vehicle including two or more mounts. The use of multiple mounts or mounting assemblies in such embodiments allows the mounts to be separated or spaced from one another, and allows for universal fit of the handlebar mounting apparatus on a broad variety of vehicles and applications.
A knuckle joint assembly to fix a handle bar to a steering shaft of a velocipede, the knuckle joint includes two knuckle parts between which the handle bar is clamped with a securing sleeve being fixed to the handle bar and engaging the knuckle parts to prevent rotation of the handle bar about its longitudinal axis relative to the knuckle parts.
