Abstract:
Various bicycle brake assemblies are described. In some embodiments, a bicycle brake assembly for applying a braking force to a wheel comprises a brake arm comprising a frame pivot joint and a brake pad pivot joint, the frame pivot joint configured to pivotally connect the brake arm to a bicycle frame to enable pivoting of the brake arm about a first axis of rotation; and a brake pad pivotally coupled to the brake arm at the brake pad pivot joint to enable pivoting of the brake pad about a second axis of rotation, the brake pad comprising a braking surface for engaging a wheel rim to apply a frictional force to the wheel rim, the frictional force having a frictional direction, wherein the first axis of rotation is not parallel to the frictional direction of the frictional force.
Abstract:
A bicycle comprising front and rear wheels, a bicycle frame and front fork supported on the front and rear wheel, a handlebar coupled to the front fork, and a component mounting assembly. The component mounting assembly includes a base coupled to the handlebar, a first component (e.g., an electronic display) supported by the base, and a second component (e.g., a gear shift lever) supported by the base. The base can comprise a clamp member of a brake lever assembly, and a position of the base can be rotationally adjustable relative to the handlebar. In one embodiment, the base includes a curved mounting surface (e.g., a cylindrical surface) that supports the second component and facilitates adjustment of a position of the second component relative to the base. The base can further include an elongated opening through which a fastener is positioned to secure the second component to the base.
Abstract:
A liquid-dispensing container includes a housing and a poppet mounted to the housing and movable along an axis between an open position and a closed position. The poppet includes a base portion comprising a relatively rigid material and an elastomeric portion comprising an elastomeric material having a tensile elastic modulus less than the elastic modulus of the rigid material. The elastomeric portion can include an outer section engaged with an outer surface of the base portion and an inner section integrally formed with the outer section and forming a self-closing valve. In one construction, the self-closing valve includes a cylindrical section having a tapered wall thickness. Preferably, the outer section includes a circumferential seal (e.g., a groove) and a circumferential clearance adjacent the circumferential seal. The outer section can further include a retention cleat having a retention surface at an acute angle relative to the axis.
Abstract:
A bicycle frame can have a main frame, a sub-frame and a shock. The sub-frame can move in relation to the main frame and the shock can be used to regulate that relationship. A linkage can also be used to regulate the relationships and control the rotation. The shock can further have a pair of extension arms to span a seat tube which is part of the main frame.
Abstract:
A bicycle including a frame that has a bottom bracket and a crankset attached to the bottom bracket. The crankset includes a sprocket assembly and a spider that has a flexible arm coupled to the sprocket assembly. The bicycle also includes a pedal coupled to the crankset and operable to propel the bicycle in response to a force acting on the pedal, and a sensor apparatus. The sensor apparatus has a sensor element positioned to sense a force transferred from the pedal to the sprocket assembly and indicative of the force acting on the pedal.
Abstract:
A bicycle assembly can include a bicycle frame that can have a main frame, a sub-frame and a shock absorber. The sub-frame can move in relation to the main frame and the shock can be used to regulate that relationship. A extension body can be used to establish a rear pivot point of the shock absorber. In some embodiments, the extension body can also be used to adjust the length of the combined shock absorber and extension body.
Abstract:
A bicycle shock absorber having a primary unit and a remote unit that can be substantially entirely outside of the primary unit. The primary unit includes a damper tube, a spring chamber, and a piston rod that supports a main piston for movement within the damper chamber of the primary unit. The main piston and the damper tube at least partially define a compression chamber. The remote unit comprises a remote fluid chamber and, in some arrangements, an inertial valve within the remote unit that preferably is responsive to terrain-induced forces and not responsive to rider-induced forces when the shock absorber is assembled to the bicycle. The inertia valve can include at least one protective coating or layer configured to contact the reservoir shaft. A fluid flow control arrangement can utilize compression fluid flow to delay closing of the inertia valve after acceleration forces acting on the inertia valve diminish.
Abstract:
A bicycle helmet adapted to be used with eyewear includes an impact-absorbing body, a resilient wiper, and an alignment feature. The impact-absorbing body has a convex exterior surface and a concave interior surface adapted to be positioned on a user's head. The impact-absorbing body further includes an aperture formed in the exterior surface and dimensioned to permit insertion of a portion of the eyewear into the aperture along an insertion axis. The resilient wiper is positioned at least partially in the aperture and arranged to engage the portion of the eyewear upon insertion into the aperture. The alignment feature defines at least a portion of the aperture and is oriented to guide the portion of the eyewear toward the resilient wiper.
Abstract:
A bicycle includes a frame, a seat, and at least one wheel rim. The rim includes a main body, and a first flange and a second flange extending from the main body for supporting a tire. A ratio of a first flange width to a flange spacing is at least 0.14. A ratio of an inner corner radius to the first flange width is preferably at most 0.5. A ratio of the first flange width to a first flange height is at least 0.75. The main body includes a cavity having a radial projection that is spaced from a radial projection of the first flange projection by a gap that is at least 10% of the first flange width. The main body further includes a nose section and a first sidewall connecting the nose section to the first flange, wherein the first sidewall includes a first concave outer surface.
Abstract:
A bicycle wheel comprises a rim and a valve assembly. The rim includes a radially inner wall having an inner opening and a radially outer wall having an outer opening. A first portion of the rim includes a first securing feature (e.g., inner threads). The valve assembly is positioned in the inner opening and outer opening and includes a second securing feature (e.g., outer threads) engaging the first securing feature. The rim can include a plate that defines the first engaging feature. The valve assembly preferably includes a valve stem and a resilient bumper coupled to the valve stem and aligned with a second portion of the rim. The valve assembly can further include a seal member compressed between the valve stem and the rim. Preferably, the seal member is positioned in an annular groove in an underside of an enlarged head of the valve stem.
