Abstract: The present invention relates to an improved structure of a treadmill, more particularly, to a frame structure of an electrical, collapsible treadmill. The frame structure includes a front frame assembly, a rear frame assembly and elevation mechanism disposed under the front frame assembly. The elevation mechanism includes a front leg assembly, a rear leg assembly and an elevation device, of which the front leg assembly and rear leg assembly are pivotally and slidably connected to each other, such that the elevation mechanism is able to support the front and rear frame assembly by means of scissors type supporting structures without the need of a base. When in use, the treadmill can be kept stable without the need of any extra fastening means; whereas when being stored, the treadmill can be folded by only flipping over the rear frame assembly upward. This design makes the convenience in storage and reduces the costs in assembling and manufacturing.

Abstract: The present invention relates to a self-lubricating structure, particularly for use in a treadmill. The structure is provided with reservoirs formed in the front and rear rollers which actuate a running endless belt, in which the reservoirs are filled with lubricant, such as silicon oil. A porous nozzle is formed in an opening on a top of each of the reservoirs, such that the silicon oil in the reservoirs is dripped from the nozzle, by means of the eccentric force generated by rotation of the rollers, to lubricate the running endless belt in order to facilitate the operation of the treadmill.

The frame includes an upright frame body and two fixed handles connected fixedly to an upper portion of the frame body. The movable handle assembly includes two pulling devices and a rotary shaft journalled on the frame. Each pulling device includes a housing with a receiving chamber, a pulley disposed rotatably in the chamber, a pull cord wound on the pulley, a handgrip fastened to an end of the cord and movable rearwardly to unwind the cord from the pulley, and a biasing unit for biasing the cord to wind around the pulley when the cord is pulled rearwardly and is subsequently released.

Abstract: An exercising device includes a hand operated member pivoted to a mounting frame and connected to a first coupler member which proceeds with a first reciprocating movement, and a lever member pivoted to the frame and connected to a second coupler member which proceeds with a second reciprocating movement. The second coupler member has a rear coupling end on which a motion guiding member, that is in slidable contact with the first coupler member, is mounted. A crank member is pivoted to a rear coupling end of the first coupler member. A synchronizing member is disposed to couple the hand operated member with the lever member such that the first and second reciprocating movements are synchronized, thereby rendering the second coupler member to run along an elliptical path.

Abstract: A hand support controlling device includes two hand support rod members and two controlling units. Each of the rod members has upper and lower rod sections, which are disposed rotatably on a base. Each controlling unit is rotatable between a first position, wherein the respective upper rod section is connected fixedly to the respective lower rod section so that the respective upper rod section can swing back and forth about a pivot axis, and a second position, wherein the respective upper rod section is fixed relative to the base and wherein the respective lower rod section is rotatable about the pivot axis.

Abstract: An exercising device includes a hand operated member pivoted to a frame and connected to a first coupler, a lever member pivoted to the frame and connected to the hand operated member by a linking bar, and a second coupler member with a front coupling end connected to the lever member and a rear coupling end in friction contact with a motion guiding member which is journalled on first and second crank members. As such, the second coupling member proceeds with a reciprocating movement in a substantially elliptical path which is restrained by the pivot connection between the handle operated member and the lever member.

Abstract: A treading exerciser has a grip member which is retained removably by a grip retainer on an upper portion of an upright post that is connected to a front end of a treading base. The grip member is adapted to be gripped by one hand of the user of the treading exerciser, and has a sensor unit mounted thereon and adapted to detect the heart beat of the user and to generate an electrical signal corresponding to the heart beat. An electrical cable unit connects the sensor unit to a control panel on the upright post, thereby enabling the control panel to monitor the heart beat of the user.

Abstract: A walking exerciser includes a treadmill body, and a threaded rod which can be driven by a driving unit to extend from or withdraw into a movable tube. When the treadmill body is disposed at a horizontal position, the threaded rod is in a withdrawn position. Extension of the threaded rod turns the treadmill body from the horizontal position to a first inclined position, where a front section of the treadmill body is disposed higher than a rear section of the treadmill body. Withdrawal of the threaded rod relative to the tube turns the treadmill body from the first inclined position to a second inclined position, where the rear section of the treadmill body is disposed higher than the front section of the treadmill body. Then, the treadmill body can be turned to a vertical position by extending and subsequently withdrawing the threaded rod relative to the tube.
