A spring enclosure trampoline includes a trampoline bed connected across a horizontal frame member. The trampoline bed is supported by a plurality of springs. Trampoline legs support the horizontal frame member above a ground surface. A trampoline enclosure supports a trampoline enclosure net from a spring enclosure netting support. The trampoline enclosure surrounds the trampoline bed and the trampoline enclosure is supported on a trampoline pole. The spring enclosure netting support is formed as a leaf spring. The leaf spring is flexible in a horizontal direction and in a vertical direction. A leaf spring vertical dimension is greater than the leaf spring horizontal dimension. A horizontal spring constant of the leaf spring, and a vertical spring constant of the leaf spring are different.

A variable stride exercise apparatus may provide a novel linkage assembly and corresponding exercise apparatus suitable for linking circular motion to relatively more complex, generally elliptical motion. Left and right cranks are rotatably mounted on a frame. A foot supporting linkage is movably connected between a rocker and the left and right cranks in such a manner that may provide a variable paths of motion controlled by a user of the apparatus.

Embodiments described herein include a substantially elongated and curvilinear polycarbonate mechanism with a chin and chest pad that may be releasably or permanently secured to the mechanism using at least a set screw or glue. The polycarbonate mechanism is flexible, durable and allows a user to customize chin elevation and exercise the chin, mouth, and throat to combat dysphagia and improve speech, voice, posture, and jaw alignment. Furthermore, the apparatus may be used with a variety of throat, jaw, and mouth exercises to isolate specific muscle groups and increase rehabilitation efficiency.

A trampoline having a frame and a jumping mat formed in a single piece from woven elasticated material. The trampoline has a flat base portion lower than the periphery of the jumping mat, and an integral side portion continuous with the base portion around the entire periphery thereof and extending to the periphery of the jumping mat. The jumping mat is connected to the frame by at least two biasing connectors to be supported under tension above ground or floor. The frame may include a first circumextending support coupled to the periphery of the jumping mat by at least one biasing connector to support the periphery of the jumping mat above the ground or floor. A circumextending safety enclosure net has first and second portions extending respectively above and below the level of the first circumextending support. the second portion extending to a second circumextending support forming part of the frame.

An exercise rod for supporting an exercise elastic rope includes a supporting member rotatably sleeved on the exercise rod. The periphery of the supporting member is provided with an annular positioning groove for cooperating with a hook. An end of the exercise rod is detachably provided with a blocking member configured to prevent the supporting member from separation, a retractable blocking button is arranged adjacent to the end of the exercise rod, and the supporting member is limited between the blocking button and the blocking member. The supporting member is rotatably sleeved on the exercise rod, and the supporting member is provided with a positioning groove matched with the hook. When the hook is subjected to force, the relative movement between the hook and the supporting member is transformed into the rotation of the supporting member, thereby eliminating the sound caused by friction and collision between parts.

A portable exercise apparatus in the shape of a square having a handle at either side, which handles are arranged rotatable on spindles such that the user can impart movement on said apparatus without changing his/her grip.

Provided herein is a hoop spring assembly for use in a mat connection system of a trampoline, in which the hoop spring assembly includes a pair of hoop portions hingedly connected by a pair of laterally positioned hinge members and a resilient member, such as an elastic band or coil spring, operably connected to each of the hinge members and extending therebetween. Mat connection systems and trampolines including such a hoop spring assembly are also provided.

The present invention discloses a stable basin-shaped trampoline, which includes a frame, multiple resiliently flexible rods with lower ends and top ends respectively, and a bouncing mat; the lower end of each rod is inserted into the frame, and the bouncing mat is bridged arranged above the top ends of the rods; the outer diameter of the bouncing mat is less than that of the frame, the frame, the resiliently flexible rods and the mat encloses into an inverted basin-shaped structure with a relatively larger lower part and a small upper part; or, the outer diameter of the bouncing mat is larger than that of the frame, the frame, the resiliently flexible rods and the bouncing mat encloses into a basin-shaped structure with a large upper part and a small lower part. The basin-shaped structure increases the stability of the trampoline and makes the trampoline not easy to flip.

A device allows user to train inner and outer thigh muscle group in standing position on a flat ground is provided. The device comprises two pivotal members that are connected through a mechanical system that governs the motion of the said pair of pivotal members. The device includes wheel systems which is mounted on each pivotal member and a mechanical system that governs the said wheel system during exercise. The device has a spring member that attached to said pivotal member for assisting the user doing the inner and outer thigh exercises. The device can have a string member that attached to the said pivotal member for adjusting the user's movement range during exercise.
