Abstract
A treadmill includes a base with two side rails and two posts with two handles are connected to the two side rails. Two guide members are connected to the two side rails and each guide member has two curve grooves which are located symmetrically about a diameter of the guide member corresponding thereto and share a common center. A frame with an endless belt is pivotably connected between the two side rails and two pin sets are respectively connected to each of two sides of a first end of the frame and movably engaged with the two curve grooves of respective one of the two guide members. Each pin set includes a bearing movably received in the curve groove so that the frame is easily pivoted by moving the pin sets in the curve grooves.
Description
- The present invention relates to a folding device for easily folding the frame with the endless belt relative to the base.
- A conventional treadmill generally includes a base with a rectangle frame pivotably connected between two sides of the base. A driving device is connected to the frame so as to drive an endless belt on the frame. Two posts extend from the two sides of the base and two handlebars are connected to the two posts and a control panel is connected between the two handlebars. In order to be conveniently stored when not in use, some treadmills are equipped with a folding device so that the frame can be pivoted upright to reduce the area that the treadmill occupies. Most of the folding devices include too many parts and involve a complicated mechanism which is costly and difficult to be maintained. Besides, when pivoting the frame, the user has to overcome certain level of resistance and this could be a problem for some users.
- The present invention intends to provide a folding device that includes two guide members with curve grooves and bearings received in the grooves so as to assist the user to easily pivot the frame upward.
- The present invention relates to a treadmill that includes a base with two side rails and two posts extend from the two side rails. Two handles are connected to the two posts. Two guide members are connected to the two side rails and each guide member has two curve grooves defined therein. The two curve grooves are located symmetrically about a diameter of the guide member corresponding thereto and share a common center. A frame has an endless belt reeving two ends thereof. Two pin sets are respectively connected to each of two sides of a first end of the frame and movably engaged with the two curve grooves of respective one of the two guide members.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
