Abstract
A bicycle stand includes a base, a front positioning rack and a rear positioning rack. The front positioning rack includes two uprights pivotally mounted on the base, a tensile spring biased on one of the two uprights, and an abutting member pivotally mounted between the two uprights to define a first placement zone between the abutting member and the two uprights. The rear positioning rack defines a second placement zone. Thus, the first placement zone, the second placement zone and the abutting member form a three-point support to hold a bicycle wheel. In addition, the angle between the first placement zone and the second placement zone can be adjusted in a determined range, so that the front positioning rack and the rear positioning rack are used to support bicycle wheels of different sizes.
Claims5
An adjustable bicycle stand comprising:
- a base;
- a front positioning rack mounted on the base;
- and a rear positioning rack mounted on the base;
- wherein:
- the base is provided with two transverse support sections and two brackets;
- each of the two brackets is provided with an arcuate slot;
- the arcuate slot of each of the two brackets has a first side provided with a first guide hole and a second side provided with a second guide hole having a dimension smaller than that of the first guide hole;
- the front positioning rack includes two uprights pivotally mounted on the two brackets respectively, a tensile spring mounted between the two brackets and biased on one of the two uprights, and an abutting member rotatably mounted between upper ends of the two uprights to define a first placement zone between the abutting member and the two uprights for supporting a front portion of a bicycle wheel, wherein the abutting member comprises two cones facing opposite one another and joined together so that the abutting member is suitable for supporting various wheel widths and sizes;
- each of the two uprights of the front positioning rack has a lower end provided with a through hole pivotally connected with the arcuate slot of each of the two brackets by a movable pulling module and a positioning bolt;
- the movable pulling module and the positioning bolt are slidable in the arcuate slot of each of the two brackets;
- and
- the rear positioning rack includes two upright pieces mounted on the base and a substantially L-shaped rotary frame pivotally mounted between the two pieces and defining a second placement zone for supporting a rear portion of the bicycle wheel;
- wherein, when in use, a bicycle wheel is rolled over the rotary frame of the rear positioning rack and a first end of the rotary frame is pivoted downward in a first direction that is clockwise or counter-clockwise so that the first end of the rotary frame moves closer to the base to receives a lower portion of the bicycle wheel and a second end of the rotary frame is pivoted upward in the first direction so that the second end of the rotary frame moves further away from the base to receive an upper portion of the bicycle wheel;
- and the bicycle wheel applies a force on the abutting member of the front positioning rack and the two uprights of the front positioning rack are pivoted forward so that the front positioning rack is moved in a determined angular range;
- wherein the first placement zone of the front positioning rack, the second placement zone of the rear positioning rack and the abutting member of the front positioning rack form a three-point support to hold and restrict the bicycle wheel solidly and stably, thereby preventing the bicycle wheel from being vibrated leftward and rightward;
- when the bicycle wheel is rolled off the rear positioning rack, the first end and second end of the rotary frame are pivoted in a second direction opposite the first direction to their respective original orientations, the force applied on the front positioning rack by the bicycle wheel disappears, and the uprights of the front positioning rack are pivoted backward by the biasing of the tensile spring so that the front positioning rack is moved to an original rest position.
