The present invention relates to an exercise device, comprising a frame, a first upper leg link and a second upper leg link, each pivotally coupled to the frame, a first lower leg link directly pivotally coupled to the first upper leg link and a second lower leg link directly pivotally coupled to the second upper leg link, each lower leg link including a foot support, a first transfer system movably coupled to the frame and including a first transfer member coupled to the first upper leg link and a second transfer member coupled to the second upper leg link, and a second transfer system movably coupled to the frame and including a right-side transfer member pivotally coupled to the first lower leg link and a left-side transfer member pivotally coupled to the second lower leg link, wherein the second transfer system is (i) physically separate and operably independent from the upper leg links and the first transfer system, (ii) operable for transferring compressive forces and tensile forces between the lower leg links, and (iii) operable for effecting correlated movement of the lower leg links irrespective of movement of the upper leg links.

The present invention relates to an exercise device, comprising a frame, a first upper leg link and a second upper leg link, each pivotally coupled to the frame, a first lower leg link pivotally coupled to the first upper leg link and a second lower leg link pivotally coupled to the second upper leg link, each lower leg link including a foot support, a first transfer system movably coupled to the frame and including a first transfer member coupled to the first upper leg link, a second transfer member coupled to the second upper leg link, and a pivot bar pivotally mounted to the frame between a first end and a second end thereof with the first end coupled to the first transfer member and the second end coupled to the second transfer member, and a second transfer system movably coupled to the frame and including a laterally extending rotatable interconnection member having a left end and a right end, a right-side linkage, including at least a right-side third transfer member pivotally coupled at a primary alpha pivot point to the interconnection member proximate the right end of the interconnection member, a right-side fourth transfer member pivotally coupled at a primary beta pivot point to the first lower leg link, and a right-side transfer coupling pivotally coupled to the right-side third transfer member at a primary gamma pivot point spaced along the length of the right-side third transfer member from the primary alpha pivot point, pivotally coupled to the right-side fourth transfer member at a primary delta pivot point spaced along the length of the right-side fourth transfer member from the primary beta pivot point, and pivotally mounted to the frame at a primary epsilon pivot point intermediate the primary gamma and primary delta pivot points on the right-side transfer coupling, and a left-side linkage, including at least a left-side third transfer member pivotally coupled at a secondary alpha pivot point to the interconnection member proximate the left end of the interconnection member, a left-side fourth transfer member pivotally coupled at a secondary beta pivot point to the second lower leg link, and a left-side transfer coupling pivotally coupled to the left-side third transfer member at a secondary gamma pivot point spaced along the length of the third transfer member from the secondary alpha pivot point, pivotally coupled to the left-side fourth transfer member at a secondary delta pivot point spaced along the length of the left-side fourth transfer member from the secondary beta pivot point, and pivotally mounted to the frame at a secondary epsilon pivot point intermediate the secondary gamma and secondary delta pivot points on the left-side transfer coupling, whereby movement of the first lower leg link causes movement of the second lower leg link irrespective of movement of the upper leg links.

The SKY WALKER machine depicted in the two accompanying Figures, namely TABLE 1 - TABLE 2, is a machine for rehabilitation, relaxation and stretching of the joints, for corrective exercises and various forms of paramorphisms. It is also designed for those with spinal problems, such as scoliosis. This machine allows the user making gymnastic exercise to strengthen the upper body muscles. All exercises practiced are carried out in suspension (without contact with the ground) and are similar to the traditional "Swedish wall bars". The uniqueness and novelty of this machine is the automatic suspension of the user through electrically controlled lifting systems, controlled by a micro-computer and some safety devices.

The SKY WALKER machine can automatically recognize the height of a person with his/her arms raised using a safety bar connected to an encoder and automatically recognizes when this person begins to use it, or when it ends to use it, through a load cell system. This machine has two functions: "lift up and down", that is only lifting, and "lift and go" allowing the user to hang to the rungs by his/her hands, moving his/her hands to take the rungs that approach the user in succession.

The present disclosure is directed to recumbent exercise machines and associated systems and methods. In one embodiment, for example, a recumbent exercise apparatus can include a seat, two linear guide tracks forward of the seat, and two pedal assemblies movably coupled to corresponding linear guide tracks positioned forward of the seat. The pedal assemblies can be configured to move back and forth along the linear guide tracks. The recumbent exercise apparatus can further include linear actuators operably coupled to each of the linear guide tracks and configured to move the linear guide tracks up and down in a vertical direction. The pedal assemblies can be configured to move in elliptical patterns when the pedal assemblies move back and forth along the linear guide tracks and the linear actuators move the linear guide tracks up and down.

A device for simulating rock climbing, comprising a sliding chain structure (4) to which handhold and foothold means (42) are mounted, enabling a user to climb the structure (4); the chain structure (4) being at least means for interlocking (52, 53) such that the first partly formed from a plurality of assemblable modules (5), each provided with first and second means for interlocking (52) of each assemblable module (5) engages with the second means for interlocking (53) of at least an adjacent assemblable module (5), thus forming a joint defining at least an articulating axis (A) perpendicular to the sliding direction of the chain structure (4).
