20080207406 | FOLDING STEP EXERCISER - A folding step exerciser includes a base including a front square socket projecting upwardly and including front and rear apertures, a horizontal support extending rearward from the support, and a transverse tube on the support adjacent rear of the socket; left and right handlebars; an upright having a top end adjustably secured to the handlebars; a pivot fixedly secured around a bottom end of the upright, the pivot having a U-shaped cross-section and including a front surface, a cavity on a bottom edge of the front surface, two triangular side surfaces, and a hole at a rear pointed end of either side surface; a bolt adapted to drive through one hole, the tube, and the other hole to pivotably secure the pivot and the socket together by cooperating with a nut, and a fastener adapted to threadably fasten the pivot and the socket together. | 08-28-2008 |
20080207415 | TWISTING EXERCISER - A twisting exerciser includes a base and a first pivot assembly and a second pivot assembly are respectively connected to the base. A first extension is rotatably connected to the first pivot assembly and a handlebar unit is connected to the first extension. A knee support unit is rotatably connected to the second extension which is rotatably connected to the second pivot assembly. Two support members are connected to the knee support unit. | 08-28-2008 |
20090042701 | PORTABLE EXERCISE DEVICE - A portable exercise device includes a body has two shafts respectively longitudinally extending therefrom and co-axially aligning with each other. Two rotors and two torsion springs are respectively pivotally sleeved on the two shafts of the body to make the two rotors reciprocally rotate relative to the two shafts. A wrench device and a stretch device respectively securely receive the two rotors for providing two exercise ways to the user. | 02-12-2009 |
20090054218 | Exerciser with Two Rotatable Disks - An exerciser includes a hollow base having two openings. Each opening includes at least one first circular groove. Two bearing members are received in the two openinigs, and each has a frame with which a plurality of balls are rotatably engaged. Two disks are rotatably mounted on the two bearing members respectively, and each disk includes at least one second circular groove and teeth defined in an underside thereof. The balls are rotatably engaged between the at least one first circular groove and the at least one second circular groove. A driving gear is located in the hollow base and engaged with the teeth of both of the two disks. | 02-26-2009 |
20100210424 | SWINGING GYMNASTIC MACHINE - A swinging gymnastic machine includes a front swinging assembly, a rear swinging assembly, a handle assembly pivotally secured to the front swinging assembly, and a pedal assembly pivotally secured to the rear swinging assembly. Each of the front and rear swinging assemblies has a spring unit. The front and rear swinging assemblies are durable and are unsusceptible of deflection. The swinging gymnastic machine also has the benefit of reducing the occupied space when it is not in use as both a front leg and the handle assembly are adapted to be folded rearwardly. A person has to exert a great force to overcome the resistance of both the front and rear swinging assemblies through the arms and calves in order to effectively exercise. | 08-19-2010 |
20100261588 | LEG STRETCHING EXERCISE APPARATUS - A leg stretching exercise apparatus includes a base seat, a telescopic handle erectly projecting from the front of the base seat, pulley sets and hinge members set on both sides of the base seat, first and second side frames hinged at each hinge member, pedal plates respectively slideably mounted on the first and second side frames by wheels under the pedal plates. An end of resistance members is hooked on to crooks under the pedal plates, and the other end is mounted around the pulley sets at the side of the base seat then hooked on to the crooks at fixed end of the first and second side frames. Thereby, a user can step both feet on the pedal plates and move the pedal plates outwardly in horizontal direction to obtain good exercising effect by the resistant force generated from the resistance members while exercising. | 10-14-2010 |
20110077137 | Swivel Exerciser - A swivel exerciser includes a base frame, left and right handlebars, a plate on the base frame, a curved rail around the plate and fixedly secured onto the base frame, left and right stop members at both ends of the rail, pivotal left and right arms, left and right pedals on ends of the left and right arms respectively and being slidable on the rail, left and right projecting plates each at one side of the left or right arm and having a through hole, and an inverted U-shaped member. In a first exercise mode, the inverted U-shaped member has both ends inserted into the through holes of the pedals for interconnection so that both the left and right pedals may swing clockwise or counterclockwise. In a second exercise mode, after removing the inverted U-shaped member either pedal may swing clockwise or counterclockwise independently. | 03-31-2011 |
20120108397 | Leg Stretching Device - A leg stretching device includes a frame having multiple lugs so as to be pivotably connected with first and second pedals. Two first protrusions extend from the first and second pedals respectively. Two side extensions respectively extend from two ends of the frame. A rod is connected to the mediate portion of the frame by an angle adjusting member. Two second protrusions extend from two sides of the rod respectively. Two resilient bands are respectively connected to the two first protrusions and the two second protrusions. The angle adjusting member adjusts the tensions of the two resilient bands. Two extension portions are respectively connected to the two side extensions and each extension portion has a support rod. The first and second pedals each have multiple positioning holes facing the support rod so as to adjust the angle of stretching. | 05-03-2012 |
20120225759 | Pull-up and Abdominal Exerciser - An exerciser includes a base having a first frame and a second frame which is pivotably connected to the first frame, and a slide device. The first and second frames are arranged to have an angle therebetween. The slide device has a damper and a roller is connected to the slide rod so as to move on the second frame. The users put the base on the floor to use the exerciser as a pull-up exerciser. The users can also overlap the first and second frames and put the first and second frames on the floor to use as an abdominal exerciser. The damper generates different resistance to obtain different exercising levels. | 09-06-2012 |
