Abstract: A manual slope-adjusting mechanism for an elliptical cross trainer having a front sleeve with side tubes at both sides of the bottom of the front end of the elliptical cross trainer. An upright tube is positioned at the center of the front sleeve. A toothed portion is formed at the top of the upright tube. Moreover, a control lever is attached to a coupling rod disposed within an upright support of the elliptical cross trainer. The other end of the coupling rod enables an up-and-down movement of a locking element such that the locking element can be engaged into or disengaged from the toothed portion of the upright tube. In this way, the supporting angle of the side tubes can be manually adjusted for adjusting the slope of the plank connecting rods.

Abstract: The invention relates to an engaging mechanism for a folding apparatus of a treadmill that is adapted to apply an appropriate locking force to a slidable pushing assembly of the folding apparatus such that an unexpected false pushing action caused by the driving behavior of a slope adjusting support by the lifting motor is prevented when the platform frame of the treadmill is moved in a horizontal operational position.

Abstract: A folding mechanism for a handrail frame assembly of a treadmill having a coupling cross shaft with a rotational disc at each side thereof for pivotally coupling to the hollow handrail frame assembly. A pull rod is received within the handrail frame assembly. In this way, two handles and a console support at the top end of the handrail frame assembly move by use of the corresponding action of the pull rod toward each other or away from each other in position when the handrail frame assembly is folded in a storage position or moved in an upright position.

Abstract: An integrated folding mechanism of a treadmill having a slide pusher supported by a pneumatic cylinder at the bottom of a platform frame thereof. In this way, the rear support may be pushed upward to bring the platform frame in a vertical stable folding position or in a flat ground-touching position when the platform frame is moved upward and downward. Meanwhile, the rear support is provided with a push rod opposing to the handrail assembly. The push rod is adapted to push a coupling cross shaft having a rotation disc at both sides thereof, respectively. In this way, the handrail assembly fixed coaxially to the rotation discs can be synchronically moved in a flat position or in an upright position.

Abstract: A folding mechanism of a treadmill having a slide pusher at the bottom of a platform frame thereof. By use of a pneumatic cylinder, the platform frame may push the rear support in an opposing direction to keep a ground-touching slide action when the platform frame is moved upward and downward. In this way, an effective, strong, and auxiliary support force is created until the platform frame is moved in a vertical storage position or in a horizontal operation position.

Abstract: The invention relates to a touch type panel switch for a swing arm of an exercise apparatus. At least one touch type panel switch for the touch of the human finger is disposed at a swing arm (or movable handrail) of an exercise apparatus. The touch type panel switch may be coupled to an electronic console of the exercise apparatus via a conducting line. Meanwhile, a preset function is achieved by a built-in microprocessor. In this way, a practical adjustment of the exercise apparatus to a proper exercise setting (such as of the speed, slope or resistance of the exercise) is ensured.

Abstract: A folding mechanism for a treadmill including a handrail assembly pivotally attached by a coupling shaft to both sides of the front end of a base frame of a treadmill. Meanwhile, a positioning unit with an engaging element is provided such that the handrail assembly can be downwardly moved toward the base frame in an initial storage position. Moreover, an n-shaped foot rest is swivelably disposed at the center of the coupling shaft by a connecting arm. In this way, the n-shaped foot rest can be extended from a front crossbar of the base frame by the synchronic swiveling action of the coupling shaft when the handrail assembly is moved in the initial storage position. In match with an n-shaped supporting frame, the base frame can be brought into an upright position to achieve a vertical and stable folding state.

Abstract: A finger-touch sensor for an exercise apparatus, comprising at least a detection recess formed at a handrail (or a swing arm) of the exercise apparatus for insertion of a human finger. At least one block-out short-wave sensor having an emitter and a corresponding receiver is fitted to the detection recess. The block-out short-wave sensor is coupled through a wire transmission line to an electronic console of the exercise apparatus such that an actual detection message obtained by the block-out short-wave sensor may conduct a pre-determined action by use of a built-in microprocessor. In this way, an easy control and adjustment of all factors (such as the exercise speed, slope or resistance, etc.) of the exercise apparatus is ensured by placing the human finger into the detection recess for blocking the emitting or reflecting signal.

Abstract: A mechanism for adjusting a saddle of a fitness apparatus that employs two telescopic adjusting elements for an easy adjustment of the inclination of the saddle tube of the fitness apparatus as well as the position of the saddle in all directions. Moreover, both of the telescopic adjusting elements each are provided with a positioning element and a plurality of the adjusting holes for an easy locking and a rapid releasing effect.

Abstract: An interactive exerciser including an upper and a lower servomotor both of which are vertically assembled to be an interacting mechanism. The upper servomotor is disposed on a support at the top of a turning shaft of the lower servomotor such that the upper servomotor can be actuated by the lower servomotor to produce a rotation in horizontal direction. Besides, the upper servomotor is perpendicular to the lower servomotor. A rocking bar is vertically disposed on a turning shaft. A target portion with sensors is mounted on the top of the rocking bar. A positioning socket is interposed between the support and the rocking bar for restricting the swinging range of the rocking bar. Accordingly, the sensors are employed to detect the position, movement direction and speed of the external objects (or the operators). Thereafter, a control unit is used to give out a command to control the rotating and swinging action of the upper and the lower servomotor.

Abstract: An electronic console with a system for indicating the motion power having one large indicating area with light color change and one setting/comparing area. Judging from the change of light color in the indicating area, the observer (operator himself and other related persons) can easily acquire the relevant information of the current dynamic status of this exercise apparatus or the current physical status of the operator. Meanwhile, in the setting mode, the user can define a specific light color of the LED in this setting/comparing area to make a simple visual comparison with the light color in the indicating area to judge whether the current exercise or physical status of the user corresponds to that of the “setting color”.
