Patent number: 7413533Abstract: An adjustable dumbbell includes a shaft provided with left- and right-handed threads, two tubes sleeved around and engaging threadedly and respectively the left- and right-handed threads, a hollow grip rod sleeved on the tubes, two support units each having upper and lower support seats disposed above and below one of the tubes, and a plurality of weights each having an engaging hole section engageable with a corresponding tube. Two adjustment knob units are respectively connected to two connecting ends of the shaft to turn the shaft and to thereby move the tubes in opposite directions towards or away from the connecting ends. Each tube is movable between the support seats to selectively engage one or more engaging hole sections of the weights.Type: GrantFiled: February 8, 2006Date of Patent: August 19, 2008Assignee: ASAI Regent LimitedInventor: William Lin

Patent number: 7410450Abstract: A portable elastic resistance exercise apparatus comprising two panels selectively affixed in a 90 degree angle. Both panels are padded for user interaction. Elastic resistance is positioned as chosen within cutouts in the back panel, at any height and with any resistance chosen. Grips on the resistance enable either grasping or hooking around limbs or body parts. The apparatus folds for portability and also includes non-skid and other anchoring devices for temporary affixation to foreign objects and surfaces. The apparatus therefore offers a truly portable, all-in-one exercise device.Type: GrantFiled: January 27, 2006Date of Patent: August 12, 2008Inventor: Kenneth F. Paulding

Patent number: 7393308Abstract: The present invention is fitness equipment with multiple functions. The fitness equipment includes a main frame, rotatable head rack, handrail rack, seat set, linkage bar, damping device and a rotatable treadle device. With the coupled configuration of rotatable head rack, seat set, linkage bar and damping device, trampling, hand-pulling and buttock lifting exercises can be achieved. The fitness equipment meets diversified requirements for both horse-riding and trampling, and also saves the space and cost.Type: GrantFiled: September 25, 2006Date of Patent: July 1, 2008Inventor: Ling-Yun Huang

Patent number: 7387598Abstract: The multifunctional portable pneumatic exercise device is a muscular exercise and training device that may be used for a multiplicity of exercises and with a wide variety of muscle groups. The exercise device includes a telescopic tube that is sealed at a distal end thereof and has a valve mounted on the proximal end thereof. In operation, the user compresses the telescopic tube and the increased air pressure within the telescopic tube causes fluid resistance, providing the user with muscular exercise. The user controls the fluid resistance through selective adjustment of the valve, which controls the volume of air escaping from the telescopic tube. Further, a pair of straps are releasably secured to either end of the telescopic tube, allowing the telescopic tube to be secured to a selected body part. The exercise device is portable, easy to operate and provides a wide range of muscular exercises for the user.Type: GrantFiled: November 24, 2006Date of Patent: June 17, 2008Inventor: Curtis J. Miller

Patent number: 7367926Abstract: A new and improved exercise treadmill may include a frame having a first end and a second end, wherein the second end is parallel to the first end. Two sidewalls interconnect the first and second end. The treadmill may further comprise a motor in order to drive a belt, which is trained over a front roller and a rear roller. A deck is positioned underneath the belt in order to support the user. The treadmill may also comprise a belt tensioning device, which provides a visual indicator so that the rear roller may be moved on each end in equal distance relative to the front roller. Another feature of the invention is a slot between the side rails and the frame so that an extended member can be inserted therein to lubricate the belt.Type: GrantFiled: January 26, 2006Date of Patent: May 6, 2008Assignee: Fitness Quest Inc.Inventor: Michael R. Clark

Patent number: 7364537Abstract: A wind resistance mechanism for an exercise apparatus is provided which includes a plurality of bendable blades for changing the form of the wind-facing side thereof or adjusting the wind-facing angle. A movable clamping device includes a hub supported on an output shaft of an exercise apparatus. A first and a second disc are mounted on the hub. At least one of both discs performs a reciprocating movement in axial direction. An external force is applied to the discs for changing the form of the wind-facing side of the blades or adjusting the wind-facing angle, thereby adjusting the wind resistance.Type: GrantFiled: June 7, 2004Date of Patent: April 29, 2008Inventors: Leao Wang, Peter Wu

Patent number: 7364535Abstract: Exercise apparatus has a biased tolerance-compensating engagement system between a seat-supporting carriage and a tubular support column to provide zero clearance between adjustment rollers and the support column, to minimize wobble during user adjustment.Type: GrantFiled: February 24, 2006Date of Patent: April 29, 2008Assignee: Brunswick CorporationInventors: Charles J. Rosenow, Lon L. Monsrud

Patent number: 7351187Abstract: An exercise device includes pedals, a belt and a hydro-kinetic brake. A user applies muscular force to the pedals and the pedal belt transfers the motion of the pedals to a flywheel shaft of the fluid brake. The pedals may be configured to accept force from a hand, foot, arm, leg and/or neck of the user. The amount of work performed by the user is derived by measuring the relative rotational speeds of two radial-blade impellers of the fluid brake. The wattage exhibited by the fluid brake during the exercise session may be recorded and associated with an identified user, whereby records of the exercise performance of an individual may be updated.Type: GrantFiled: October 20, 2006Date of Patent: April 1, 2008Inventor: Joseph Seliber

Patent number: 7341545Abstract: Steel cables on fitness equipment, through repeated use, will build up undesired torque, due to irregular and unpredictable turns and spins. Such accumulated and undesired torque has a tendency to cause the cable to derail from the grooves on the gears it is supposed to stay and slide. The grab bar or handle bar, where a user grabs to start workout routine, likewise, has a tendency to turn or spin in an uncontrollable way and could potentially injure a user. Present invention effectively releases the undesired torque and restores the cable to its neutral and relaxed state, so that the fitness equipment will experience less malfunctioning, and user safety is enhanced.Type: GrantFiled: May 28, 2004Date of Patent: March 11, 2008Inventor: Guofang Cao
