Ellipse exerciser with inclination adjustment unit

摘要

An ellipse exerciser includes a base, a rail frame having two rails, an ellipse unit having two pedals and two roller units, and an adjustment unit having a bottom part and a support frame. The roller units are moved along the rails of the rail frame. The bottom part has two slots and each slot has teeth. Two guide boards are pivotably connected to the two respective outsides of the bottom part. Each guide board is connected with a spring. The support frame has a rod and two ends of the rod are respectively engaged with the slots. The guide boards each have a stop portion to guide the rods. When the support frame is rotated to different angular positions relative to the bottom part, the rods are engaged with different teeth so as to adjust the inclination of the rails.

1. An ellipse exerciser comprising:
a base; a rail frame having two rails; an ellipse unit having two pedals which move along two elliptical paths of motion, each pedal connected with a roller unit, the two roller units movable along the two rails of the rail frame; an adjustment unit having a bottom part and a support frame, the bottom part fixed to the base, wherein when the support frame is rotated to a first angle relative to the bottom part, the support frame supporting the rail frame rotates to a second angle relative to the base, wherein when the support frame is rotated to a third angle relative to the bottom part, the support frame supporting the rail frame rotates to a fourth angle relative to the base; wherein the bottom part having two slots and each slot having multiple teeth extending from an inner end thereof, two guide boards being pivotably connected to two respective outsides of the bottom part, there being two first springs, with each guide board having an individual said spring connecting one of the guide boards and the bottom part, each guide board having a stop portion bent therefrom, the guide boards each are pulled by the first spring to move the stop portion toward the inner end of the slot, the support frame has a rod on an underside thereof and two ends of the rod are respectively engaged with the slots, wherein when the support frame is rotated to the first angle relative to the bottom part, each of the stop portions is pulled by the first spring and presses the rod which is engaged with a valley between one pair of adjacent teeth, wherein when the support frame is rotated to the second angle relative to the bottom part, each of the stop portions is pulled by the first spring and presses the rod which is engaged with another valley between another pair of adjacent teeth, wherein when the rod is moved to a front end of the slot and the rod is moved to a top of the stop portion, the rod is moved on the top of the stop portion, wherein when the rod moves on the top of the stop portion and reaches a rear end of the slot, the rod is located below the stop portion.
