Abstract: A steering damper particularly for mountain bicycles of the type having a steer-tube including a cylinder having closures at the ends filled with oil of high viscosity. Within the cylinder there are a dam and vanes. The steering damper is integrated with the steer-tube and with the handlebars and steer-stem. The vanes of the steering damper are connected to the frame and are fixed. The housing and dam connected internally to the housing are disposed in, and connected to, the steer-tube so that when the handlebars are rotated, the housing and dam are rotated relative to the vanes. When the handlebars are being displaced from center, pressure is applied to the oil between the dam and a vane and the movement is damped. On the return stroke of the handlebars, the one-way valve in the vane involved is open, the oil between the dam and the vane is discharged, pressure is reduced and the damping is suppressed.

Abstract: A steering damper particularly for a bicycle which is integrated into the bicycle. The damper includes a housing closed at the top by a cap from which sidewalls extend and at the bottom. The housing contains a damping medium. Within the housing thee is a dam connected to the housing and a single vane connected to a shaft which passes through the housing. There is an opening in the shaft which communicates with the vane to circulate the medium during the damping when the bicycle departs from the path in which it is being directed and during the suppression of the damping when the bicycle returns to the path along which it is directed. The effective cross-section of the opening in the shaft is of sufficient magnitude to permit unrestricted flow of the medium. The housing and dam are supported within the steer-tube by the clamp from the steer-stem and are connected to the clamp by a tapered bearing rotatably with the steer-tube as the steer-tube is rotatable by the handlebars.

Abstract: A steering damper particularly for mountain bicycles of the type having a steer-tube including a cylinder having closures at the ends filled with oil of high viscosity. Within the cylinder there are a dam and vanes. The dam is rotatable on a shaft from a center position towards and away from the vanes. The shaft is connected to the handlebars and is rotatable with the handlebars which are connected to control the steering movement of a steerable wheel through the steer-tube. The steering damper is integrated with the steer-tube and with the handlebars and steer-stem. The vanes of the steering damper are connected to the frame and are fixed. The housing and dam connected internally to the housing are disposed in, and connected to, the steer-tube so that when the handlebars are rotated, the housing and dam are rotated relative to the vanes. When the handlebars are being displaced from center, pressure is applied to the oil between the dam and a vane and the movement is damped.

Abstract: A steering damper for mountain bicycles including a closed cylinder filled with oil of high viscosity including a dam and vanes rotatable from center towards and away from the dam. The vanes are connected rotatably with the handlebars in reciprocal steering relationship with a steerable wheel. When the steerable wheel encounters an obstruction displacing it from center, the vanes are driven in the oil one towards and one away from the dam respectively decreasing and compressing and increasing and relaxing the corresponding volumes of the oil and damping the movement of the handlebars. The damping against the return of the handlebars and steerable wheel to center is suppressed by one-way valves in the vanes which open when the compressing vane is retracted, recesses in the cylinder providing a non-resistant path for the oil moving through the valve in the retracting vane.
