Abstract
Abstract A steering rod, in particular for a wheeled vehicle is connected to a steering column by a centrally located connecting arrangement. The connecting arrangement has an articulated arm that can be bent about at least one hinge pin and fixed in various locking positions by a fixing means. The locking positions are defined on two opposing locking surfaces that are inelastically formed in the articulated arm parts, by pins engaged in depressions. The clamping distance of the fixing means is smaller than the length of the pins. Additional means completely release the pins from the depressions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
251 words
A steering rod device for bicycles comprising a steering rod, and a centrally located connecting arrangement for connecting said steering rod to a steering column, said centrally located connecting arrangement comprising an articulated arm, said articulated arm comprising at least two arm parts, said two arm pads comprising a first arm part fixedly linked to said steering column and a second arm part having at least one tube clamp with a securing screw for connection to said steering rod, said two arm parts being swivellable about an axis normal to the longitudinal axis of said steering column and normal to the longitudinal axis of said two arm pads by means of a hinge joining said two arm parts, said hinge comprising opposed locking surfaces on said two arm parts, said opposed locking surfaces comprising a first locking surface having projections for engaging depressions arranged on a second locking surface opposed to said first locking surface. said centrally located connecting arrangement further comprising fixing means for fixing said two arm parts in different locking positions that are defined by engagement of said projections and said depressions, said fixing means having a clamping distance smaller in length than said projections, for loosening the connection of said two arm parts, but not releasing said projections from said depressions, said centrally located connecting arrangement further comprising release means for completely releasing said projections from said depressions, and said fixing means and said release means being operable when riding the bicycle without releasing said steering rod.
Claim 2
Dependent Claim
251 words
A steering rod device for bicycles comprising a steering rod, and a centrally located connecting arrangement for connecting said steering rod to a steering column, said centrally located connecting arrangement comprising an articulated arm, said articulated arm comprising at least two arm parts, said two arm pads comprising a first arm part fixedly linked to said steering column and a second arm part having at least one tube clamp with a securing screw for connection to said steering rod, said two arm parts being swivellable about an axis normal to the longitudinal axis of said steering column and normal to the longitudinal axis of said two arm pads by means of a hinge joining said two arm parts, said hinge comprising opposed locking surfaces on said two arm parts, said opposed locking surfaces comprising a first locking surface having projections for engaging depressions arranged on a second locking surface opposed to said first locking surface. said centrally located connecting arrangement further comprising fixing means for fixing said two arm parts in different locking positions that are defined by engagement of said projections and said depressions, said fixing means having a clamping distance smaller in length than said projections, for loosening the connection of said two arm parts, but not releasing said projections from said depressions, said centrally located connecting arrangement further comprising release means for completely releasing said projections from said depressions, and said fixing means and said release means being operable when riding the bicycle without releasing said steering rod.
