Abstract:
A stair climber apparatus has a frame and a plurality of stairs that are pivotably connected together in series and travel in a loop with respect to the frame. The plurality of stairs comprises a first stair having a tread and a riser. The tread and riser are pivotably connected together at a first pivot axis. The tread has a tread surface that supports an operator's foot. A stopping member is on the tread. The stopping member has a stop surface that extends transversely to and upwardly from the tread surface and prevents the operator's foot from overshooting the first pivot axis and engaging the riser as the operator steps onto the tread surface when the riser is pivoted away from the tread.
Abstract:
An elliptical exercise machine, in one embodiment, includes a first assembly pivotally coupled with a second assembly and at least one assist mechanism. The first assembly includes a first frame member, a rotational resistance mechanism associated with the first frame member, a first foot support member pivotally coupled to a portion of the rotational mechanism and a second foot support member pivotally coupled to another portion of the rotational mechanism. The second assembly includes a second frame member, a first reciprocating arm pivotally coupled with the second frame member, a second reciprocating arm pivotally coupled with the second frame member. In one embodiment, the assist mechanism may include a folding assist mechanism to provide resistance between the assemblies during a folding transition. In another embodiment, the assist mechanism may include a rotational assist mechanism to assist a user in transitioning the elliptical machine to an upright storage position.
Abstract:
An exerciser, preferably in the form of a stepper with a fluid resistance system guides stepper treadles angularly downward and outward from the center of the stepper. According to an embodiment bellows that support treadles angle downward and outward. An embodiment of the invention involves an exercise resistance device with depresser plates angled to receive a user's appendages at targeted angles. A more specific embodiment involves a targeted air support or resistance stepper system with angled treadles that compress bellows connected by air passages.
Abstract:
The present disclosure relates to a fitness stepper, and more particularly, to a fitness stepper designed to enable exercise to be performed by continuously stepping on ladder rungs along an inclined surface, such as when actually climbing stairs or hiking up a mountain, through an unpowered means without the use of a motor. The fitness stepper of the present disclosure is configured using: four ladder rungs connected perpendicularly to a rotating shaft and parallel to the surface of the ground, wherein the rotating shaft is rotated by means of the weight of the user; and a device enabling the length of a rotor connecting the rotating shaft and the ladder rungs to be varied so as to enable the ladder rungs to slide obliquely downward at an angle toward the surface of the ground and to rotate as they rise, thus enabling a ladder-climbing exercise to be continuously performed by stepping and climbing alternately with each foot on the infinitely rotating ladder rungs. Also, the fitness stepper of the present disclosure may be manufactured at a low cost, does not consume electricity, and generates virtually no noise or vibrations, such that the fitness stepper can be conveniently set up in a home, thereby enabling aerobic exercise to be easily performed in tight interior spaces.
Abstract:
An impact absorbing exercise device includes a stepping platform having an upper surface and a lower surface. An impact absorbing panel is configured to be releasably coupled to the upper surface of the stepping platform. The impact absorbing panel includes a resilient wear surface and an impact absorbing material positioned between the resilient wear surface and the stepping platform.
Abstract:
A pulley assembly for removably fastening an arm cord to an exercise apparatus is disclosed. The pulley assembly includes a yoke having a central portion and a pair of parallel leg portions, the central portion having a bore therethrough, a pulley wheel rotatably supported between the yoke leg portions by an axle, and an elongated stem having an axially extending shaft portion protruding through the bore. The shaft portion has distal end portion having an L shaped slot formed therethrough. The L shaped slot forms a hook shaped end to the shaft portion. A tapered coil spring over the shaft portion of the stem, has a small end and a large diameter around the shaft portion of the stem. The spring biases the hooked end away from an eyebolt on the exercise apparatus to keep the pulley assembly engaged with the eye bolt and hence fastened to the exercise apparatus.
