Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

The application discloses a pressure biofeedback system with improved safety, quality and precision.

An exercise machine that provides a generally consistent resistive force against a user who walks, steps, or runs away from the machine as part of a strength training exercise program. The machine is built upon a movable frame having transport wheel assemblies that allow the exercise machine to be placed on an indoor floor surface or on the ground outdoors. The frame of the device further supports three parallel spinning assemblies that together allow a length of linear strap attached to the user to run out from the machine and thereafter be retracted or rewound back into the machine. The spinning assemblies include a flywheel assembly, a spool assembly, and a spring assembly, each co-axially arranged on a spin axle extending across the frame. The spring assembly is fixed against the frame and incorporates a coil spring that tightens with the rotation of the spin axle in a first direction (allowing the linear run-out strap to extend out from the spool assembly). The coil spring in the spring assembly thereafter tends to direct the rewinding of the strap back onto the spool assembly. The coaxial flywheel assembly provides both an initial stationary inertia and a subsequent rotational inertia. The flywheel acts as a governor to balance the changing forces associated with the resistive force increasing in the spring assembly. Positioned on the spin axle between the flywheel assembly and the spring assembly is a spool assembly that allows the strap to unwind and subsequently to be wound back onto the spool. A guide strap may be provided around the spool to maintain the linear run-out strap within the spool assembly. A resistance adjustment assembly presses a brake pad against the perimeter surface of the flywheel to adjust the force required to direct rotation of the system. A weight horn bracket is provided to add additional disc weights if necessary.

A static and dynamic exercise apparatus has a spatially displaceable object coupled to a frame and a force applicator. A resistance system exerts a first level of resistance that prevents the movement of the object by the application of a user-applied force, thereby allowing a user to generate a static, or isometric, force on the force applicator and object. The resistance system may then be released, to allow movement of the object, thereby rapidly transmuting the static force into a dynamic movement. In various embodiments, the object is a plurality of weights, the force applicator is a weight lifting bar, and the resistance system is a pneumatically actuated piston that is capable of releasably holding the weights and weight bar to the frame.

A system and method of using an exercise system having a resistance structure of an exercise bar connected to cables, which cables are connected to at least one pneumatic cylinder that creates resistance, wherein the resistance is adjusted by the user via actuators in the exercise bar, so that the user does not need to release the exercise bar to adjust the resistance. The system may be supported by a frame, and the pneumatic cylinder may be connected to an equalizing tank that may be housed within or integrated into the frame. The system may include a monitor to visually display system parameters and other information to the user. The system may calculate resistance and work done by the user by measuring piston displacement and speed, as well as using accelerometers or other devices integrated into the exercise bar.

Disclosed herein are various embodiments of an exercise apparatus. In certain embodiments, an exercise apparatus comprises a frame and a seat assembly, the seat assembly comprising a seat, the seat configured to move between a first position and a second position, wherein the first position accommodates use of the exercise apparatus by a user sitting on the seat and wherein the second position accommodates use of the exercise apparatus by a user sitting in a wheelchair. The seat assembly may be pivotably coupled to the frame. The seat assembly may comprise a stop configured to inhibit movement of the seat, and may further comprise a biasing element that is biased to disengage the stop.

A jumping assistance system is disclosed herein. The jumping assistance system includes a base frame assembly, a support stand, an upper frame assembly, and a training harness that combine to provide a secure support structure from which a user may perform a training or exercise routine that involves repeated jumping movements or pull-ups. The jumping assistance system is useful for suspending a user beneath the upper frame assembly by a set of resistance bands or other secure means that may still allow the user's feet to come in contact with the ground. From this supported position, the user may engage in a series of jumping exercises or extended workout routines while minimizing the impact of repeated jumps to their joints, feet, and other body parts. The jumping assistance system also features a series of hinges that allow the support device to be conveniently folded for storage purposes.

The invention relates to a reflective composite material (V) having a carrier (1) consisting of aluminum, having an interlayer (2) which is present on a side (A) on the carrier (1) and is composed of a varnish, and having an optically active multilayer system (3) which has been applied atop the interlayer (2) and consists of at least three layers, wherein the upper layers (4, 5) are dielectric and/or oxidic layers, and the lowermost layer (6) is a metallic layer which consists of silver and forms a reflection layer (6). To increase the aging resistance, it is proposed that the interlayer (2) comprise an organic layer-forming varnish or be formed entirely from such a varnish that has been cured in an ionic photopolymerization and crosslinking or that has been cured after UV irradiation by free-radical photopolymerization and crosslinking.

A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.
