Angle adjustable pedals for elliptical exercisers
View Patent ↗An angle adjustable pedal assembly for elliptical exercisers includes a pedal frame and a pedal which is pivotably connected to two sides on an end of the pedal frame. Each side wall has a hole with three notches defined in an inside of the hole and the pedal has two connection plates each of which has a reset slot and a set slot which communicates with the reset slot. A pin extends through one of the reset slot and the set slot, and is engaged with one of the three notches in the side walls so that the pedal can be set at different angle relative to the pedal frame by engaging with one of the three notches in the side walls.
1. An elliptical exerciser comprises a frame having a wheel connected thereto and a crank is connected to the wheel, each one of two ends of the crank having an extension link and the extension links located on two sides of the wheel, a mediate portion of a connection bar pivotably connected to an end of each of the extension links and the other end of each of the extension links connected to an end of a handle, an end of each of the connection bars pivotably connected to a link which is pivotably connected to the frame, two rails having an end pivotably connected to the frame, the other end of each of the rails connected to a lifting device, a pedal assembly that includes:
