Definitions

  • the present invention relates to a height adjustment mechanism for a handlebar of a cycle. So that a bicycle may be matched to the rider it is beneficial that a number of parts of the bicycle are adjustable in their position oii the bicycle frame. In particular the seat and the handlebars are moved to suit the size of the rider and their reach from seat, pedals and handlebar. The adjustments are commonly carried out for a rider when static; however this is a compromise given that when a bicycle is in use the needs of the rider may be variable during the ride. This is most evident with the application of Mountain Bikes when the terrain, attitude and velocity of the bicycle mean that the rider chooses to move about relative to the frame and thus the handlebar is fixed and therefore physically limiting.
  • a hinging stem moves through an arc, thus when the handlebar is at full height the centreline of the handlebar may pass very close to the axis of the steer tube, the converse being true for when the handle bar is down and the stem is horizontal and thus the handlebar is moved forwards of the pivot point of the front wheel by the radius of the arc traversed by the hinging stem.
  • a drawback of this variation of handlebar centreline to steerer tube centreline is that it imposes a variance in the torque requirement to turn the bicycle front wheel and hence a variable sensation of feel and response.
  • a further drawback of the hinging stem is that the hinging and the parallelogram system impose bulky features additional to a conventional stem to steerer tube fitment in the zone of the stem directly in front of the rider.

Close down of Locking Valve 5 prevents the Hydraulic Fluid 16 above the Rod Head 18 from physical communication with the hydraulic fluid beneath it, this closure of passage stops any fluid flow and so hydraulically locks in place the Rod Head 18.
