An exercise machine that enables users to perform both leg press and knee extension exercises efficiently. The exercise machine includes a base platform and an adjustable backrest that supports the user's back to facilitate the leg press exercise. The backrest slides along guide bars, allowing for customizable reclining positions, and its angle can be adjusted for user comfort. A footrest, hinged at the base platform, engages leg muscles during the leg press exercise and is connected to a weight stack for adjustable resistance. The footrest's range of movement can be controlled to prevent excessive rotation. Additionally, a lever pad is positioned to support the user's knees during knee extension exercises, with adjustable resistance through a second weight stack. The lever pad's range of motion can also be regulated for safety. The exercise machine integrates both exercises, promoting full-body muscle engagement and enhancing strength and cardiovascular health.

An extension-assisted hinged knee replacement comprises a femoral component, a tibial component, and a torque actuator operably interfacing the two components. The torque actuator is configured to apply extension torque based on the flexion angle of the knee, with the torque peaking between 0° and 90° of flexion. The implant may include a passive biasing element, which can be compressed or tensioned to enhance torque application, particularly during critical phases of knee extension.

An apparatus for knee extension and flexion worn about a leg of a user. The apparatus includes a frame having a generally parallel first and second frame sides, a handle end and a foot support end. The first frame side includes a first upper leg portion, a first lower leg portion, and a first knee hinge. The second frame side includes a second upper leg portion, a second lower leg portion, and a second knee hinge. The apparatus includes a handle having a handle pivot end and a handle distal end and the handle configured to rotate the first lower leg portion relative to the first upper leg portion. The apparatus includes a knee angle sensor to measure an angle at the first knee hinge.

An apparatus for enhancing knee flexion and extension exercises by integrating dynamic movement and coordination across the upper body, core, and lower body. The apparatus includes a base platform with an adjustable backrest that supports the user's back. The apparatus includes multiple adjustable lever pads for knee extension and flexion exercises, each with customizable resistance via weight stacks and range controllers to ensure safety and comfort. A third lever pad allows for lateral hip flexion exercises, promoting engagement of core and hip muscles. These components are designed to accommodate users of varying sizes and fitness levels, while the apparatus facilitates multi-planar movement, improving neuromuscular coordination, balance, and reducing the risk of injury through natural, functional exercise patterns.

This application discloses a knee extension exercise assistive device, comprising: a base unit and a pressure unit; the base unit includes a flat base body, with a thigh support pad formed on the upper side of its first end and a calf support pad formed on the upper side of its second end; a through-hole extending in the vertical direction is formed at the middle position of the front part of the base unit; a threaded hole extending in the front-rear direction is formed on the front side of the front part of the base unit; the threaded hole communicates with the through-hole; a bolt is installed in the threaded hole; the pressure unit includes: a knee pressure plate and a connecting rod; a recessed portion corresponding to the knee is formed on the lower side of the knee pressure plate, and the knee pressure plate is used to press on the knee of the subject from above; the upper part of the connecting rod is curved, and the lower part is vertical; the upper part of the connecting rod is fixed together with the upper part of the knee pressure plate; the lower part of the connecting rod is inserted into the through-hole of the base body; the end of the bolt in the threaded hole of the base body abuts against the outer surface of the lower part of the connecting rod.

The application discloses a limb auxiliary exoskeleton device based on self-adaptive adjustment and energy recovery, which comprises a waistband assembly, two groups of main and passive power assisting mechanisms arranged on both sides of the waistband assembly, limb auxiliary support assemblies arranged on opposite sides of the two groups of main and passive power assisting mechanisms respectively, and energy storage mechanisms arranged on each limb auxiliary support assembly, wherein when the limb auxiliary support assemblies are bent and stretched, the energy storage mechanisms store the potential energy of the movement to further provide power assistance for the active knee extension action of the corresponding limb auxiliary support assembly. Through the on-off control of the electric push rod and the action of the extracorporeal sensing module, the main and passive power assisting mode of the lower limbs is selectively provided, the passive bending and stretching of the lower limbs are adjusted in real time according to the action trend, different activity requirements are met, in addition, the energy storage mechanism is arranged, the energy can be stored in the main and passive activities, and the stored energy is used in the power assisting action, so that an energy collection and release process is realized.

The invention relates to a fitness machine for performing a knee extension exercise of a user with at least a torso, a hip, an upper leg and a lower leg, which fitness machine comprises : a main frame; an upper leg support connected to the main frame and extending between a distal and a proximal outer end, such as for instance an upper leg pad, which upper leg support is configured to support at least one upper leg of the user in a first plane during use; a torso support, such as for instance a back pad, connected to the main frame, which torso support is configured to support the torso of the user in a second plane during use; a pivot arm connected to the main frame and configured to be operated with the lower leg during use, which pivot arm is rotatable about a pivot axis lying close to the distal outer end of the upper leg support, wherein the first and the second plane are oriented relative to each other for supporting the at least one upper leg and the torso of the user in an exercise position, between o maximum hip extension on one hand and a maximum of 30° hip flexion on the other, while the exercise is being performed.

The invention discloses a knee joint energy storage assisting exoskeleton which comprises a first protection plate, a second protection plate and a connecting assembly, and the first protection plate is used for being connected with the thigh of the human body; the second protection plate is used for being connected with the shank of the human body, and the first protection plate and the second protection plate are matched to support the exoskeleton. The connecting assembly is used for connecting the first protection plate and the second protection plate and comprises a supporting rod and a damping base, one end of the supporting rod is connected with the first protection plate, and the other end of the supporting rod is rotationally connected with the damping base which is connected with the second protection plate. A damping energy storage device is arranged on the damping seat and abuts against the supporting rod. By means of the matching relation that the damping energy storage device arranged on the damping seat abuts against the supporting rod, mechanical energy is converted into elastic potential energy to be stored in the rotating process of the supporting rod, the impact load is dynamically buffered, and the damping and pressure reducing effect is improved; the shock absorption and energy storage device absorbs energy in the knee bending stage and releases energy in the knee stretching stage, and physical output of a user is remarkably reduced.
