A segmented inflatable structure device includes a plurality of body segments positionable together to join into an assembled condition to form a structure when inflated. Each body segment has at least one opening. Each opening in each body segment is adjacent to and aligned with an associated opening on an adjacently positioned one of the body segments defining an interior space when the body segments are in the assembled condition to form the structure. Each of a plurality of segment fasteners releasably couples adjacently positioned body segments together in the assembled condition. A main air inlet is positioned in one of the body segments for connection to an air pump for injecting air into the interior space whereby the structure is inflated.

A protective rowing device for compression of the abdomen is provided that comprises a brace and U-shaped support member that may connect to a rowing machine seat and rail.

Trampoline systems containing multiple trampoline jumping surfaces are disclosed. Methods of making and using trampoline systems containing multiple trampoline jumping surfaces are also disclosed.

An exercise and therapeutic device includes a treadmill comprising a running belt coupled to a treadmill frame and an offloading system coupled to the treadmill. The offloading system includes an air chamber surrounding the running belt adapted to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber, adapted to receive a user so that, in an operating condition, at least a portion of a user is received in the user seal and positioned within the air chamber and to seal the air chamber around the user, a pump operable to inflate the air chamber, at least one strap coupled to the treadmill frame and adapted to restrict the expansion of the air chamber and adjust a spacing of the user seal relative to a running surface of the running belt when the air chamber is inflated.

An in-goal ball return device, the ball return device is a material implement having a front edge, side edges, and a rear edge. The device is configured for attachment within a goal, the goal having a supporting net mesh. The device has a plurality of closed loops disposed along the rear edge and side edges. The device includes a lacing cord for threading through any number of the closed loops and the net to secure the material implement to the net mesh. The device forms a continuous angled surface between the front and closed portion of the goal when attached.

There is no other self-inflatable football collar in the American football equipment market. Upon impact to the helmet, this collar is designed to catch in lower lip of the football helmet and transfer the force from the head and neck of the collar and shoulders.

An exercise device includes a strap. The strap includes a first surface and a second surface opposite the first surface. The strap is configured to be secured to a lower leg of a user such that the first surface of the strap interfaces with the lower leg of the user. The exercise device further includes a ball including an outer surface configured to be held by the user, a first connector extending from the ball, a second connector extending from the second surface of the strap, and a tension member. The tension member includes a first coupling mechanism and a second coupling mechanism at opposite ends thereof and configured to be releasably coupled to the first connector and the second connector via the first and second coupling mechanisms.

Systems, methods, and devices for protecting a user head are provided. In one example, a computer-implemented method can comprise receiving, by a processor operatively coupled to a helmet device, helmet data comprising at least one of statistical data, statistical models, or natural intelligence algorithms. The computer-implemented method can also comprise inflating, by a gas delivery system of the helmet device, a pressure chamber element of the helmet device based on the helmet data. Furthermore, the computer-implemented method can comprise scanning, by a sensor system of the helmet device, surrounding environments of the helmet device for object data.

The present invention proposes a float with a retractable foot rest, comprising a lying float body, a supporting element, a protecting assembly and a foot rest cushion. The supporting element and the protecting assembly are installed in a lying float splicing body; the foot rest cushion that can be retracted or expanded is installed at the lower end of the supporting element; and the foot rest cushion is connected with the supporting element. When the float is worn, the foot rest cushion can be expanded to replace an additional bath towel that needs to be placed on the ground to prevent dirt. After wearing, the foot rest cushion can be retracted below the supporting element, or as required, the floating body is spliced on the lying float body, and the foot rest cushion is connected with the floating body.

A method for exercising muscles in an ankle, foot, and/or leg of a user includes positioning a foot of a user onto a first body of an exercise device. The first body is spaced away from a second body of the device and pivotably connected to the second body of the device at a pivot axis. The pivot axis is adjacent to a central portion of the first body. The method includes rotating the first body about the pivot axis, with the foot, against a first resistive force. Rotating the first body includes subjecting the foot to a first motion. The method includes positioning the foot onto the second body. The method includes rotating the second body about the pivot axis, with the foot, against a second resistive force. Rotating the second body includes subjecting the foot to a second motion, the second motion being different than the first motion.
