Abstract:
An adjustable rear wheel hood system has a movable hood, so to be longitudinally adjusted to accommodate shrinking wheels (due to wear), or other requirements. A longitudinal slot is aligned between the rear wheel hood and the deck, and after adjusting the hood-to-rear wheel separation to a desired amount, the hood is secured to the deck. Either the deck or hood is configured with the slot, while the other piece has holes and/or alignment features that align the pieces together, provide a way to secure the pieces together, and also prevent lateral movement of the hood. A similarly configured adjustable non-braking rear hood is described.
Abstract:
An arrangement for controlling the activity of an actuator (AK) of a brake of a motor vehicle has a first path for a first signal (TRIG1) relating to the activity of the actuator (AK), a second path for a second signal (TRIG2) relating to the activity of the actuator (AK), and a circuit (MOSFET, TRANS, RES3, BAT2) enabling the actuator (AK) to be activated in such a manner that the actuator (AK) is activated if a determined modification of the first signal (TRIG1) and also a determined modification of the second signal (TRIG2) is present. The determined modification of the first signal (TRIG1) is in the opposite to the determined modification of the second signal (TRIG2).
Abstract:
A bicycle brake actuated by a control cable has a first main brake arm and a second main brake arm mounted for pivotable movement with respect to the first main brake arm. A first transfer brake arm is pivotally connected to the first main brake arm, and a second transfer brake arm is pivotally connected to the first transfer brake arm and pivotally connected to the second main brake arm. The first main brake arm has a cable guide for receiving the control cable. The first transfer brake arm has a cable anchor for receiving the control cable, the control cable extending between the cable guide and the cable anchor. The first main brake arm and second main brake arm each support a brake shoe and apply braking force to a wheel when actuated.
Abstract:
A bicycle brake device includes first and second brake arms. The first brake arm includes a first brake arm mounting portion for mounting the first brake arm to a bicycle frame member, a first brake pad mounting portion, and a first control interface portion. Similarly, the second brake arm includes a second brake arm mounting portion for mounting the second brake arm to the bicycle frame member, a second brake pad mounting portion, and a second control interface portion. A biasing member is operatively coupled to the first brake arm so that the first brake pad mounting portion is biased in a selected direction. A bias communicating member is operatively coupled between the first brake arm and the second brake arm to communicate biasing force from the biasing member to the second brake arm.
Abstract:
A brake assembly for braking a wheel of a bicycle includes left and right brake arms and left and right brake shoes. Each brake shoe includes a holder mounted to the respective brake arm, a pad unit mounted on the holder and having a friction surface that is brought to frictionally engage a rim side of a wheel rim of the wheel, and a magnetically attracting unit mounted on the holder for establishing a magnetic field such that, in the course of a braking action, the strength of the established magnetic field is gradually increased to be of a magnitude sufficient to generate a dragging force to decelerate the running speed of the wheel rim until the friction surface frictionally engages the rim side.
Abstract:
There is provided a caliper brake attachment tool which comprises: a supporting rod; a fixed part provided to one end side of the supporting rod capable of fixing an existing caliper brake; an applying part provided to the other end side of the supporting rod and applicable to a seat tube of the bicycle; and an engaging recess provided between the fixed part and the applying part in the supporting rod engageable with a bridge to connect a right-and-left pair of seat stays of the bicycle.
Abstract:
An apparatus for mounting a brake control element to a bicycle hub brake comprises a rotating member structured to be rotatably mounted relative to a fastening bracket so that rotation of the rotating member actuates a brake mechanism, wherein the rotating member includes a brake control element mount. The rotating member also has a cable winding surface to wind a brake actuating cable thereon. A brake control element attachment unit is structured to be attached to the brake control element mount, wherein the brake control element mount includes a locking structure such that rotation of the brake control element mount relative to the brake control element attachment unit locks the brake control element attachment unit to the brake control element mount.
Abstract:
Manual braking system with a variable braking force for a wheelchair. Caliper type brakes positioned to mount on and exert braking force on disks mounted to interior “disk” hubs rotatably mounted to the wheelchair frame wheel hubs are mated with the “disk” hubs with a push button release pin allowing the wheel to be quickly removed without disturbing disk braking system. Caliper brakes are actuated by a manual lever arm, cable and pulley combination mounted to the frame of the wheelchair. The lever is provided with and without a plunger mechanism. A plunger mechanism allows the user to maintain the manual braking force exerted on lever without hands. The plunger mechanism is fixably mounted and positioned to insert a plunger head into notches on the lever. The force exerted by the plunger head is sufficient to hold the plunger head within the notch and prevent movement of the lever without manual force.
Abstract:
A fiber reinforced plastic bicycle wheel rim having an aerodynamic section is formed of two mating halves, without additional structural reinforcing members, using laminations of layers of unidirectional fibers crossing one another and having semicircular layers of non-crossing fibers orientated parallel to a point of tangency, the non-crossing layers being proximate tire well apexes and the spoke bed, including, in a preferred embodiment, a lamination of machinable materials at the braking surfaces.
Abstract:
A dual cable force balancing mechanism for use with a pair of main brake cable segments and a pair of rear brake arms of a bicycle. The dual cable force balancing mechanism includes a brake arm actuation assembly defining a longitudinal axis positionable between the main brake cable segments. The brake arm actuation assembly is attachable to the rear brake arms. The dual cable force balancing mechanism further includes a pivot member including main attachment portions disposed about the longitudinal axis for respectively attaching the main cable segments. The pivot member is rotatably coupled to the brake arm actuation assembly for pivoting the pivot member with respect to the longitudinal axis.
