The present invention discloses a power adjustment device. The power adjustment device includes a steel cylinder and a piston arranged inside the steel cylinder in a sliding mode, wherein the piston is fixedly provided with a guide rod, the guide rod being connected to a dustproof cover in a sliding mode, and a steel cable being fixed to an upper end of the guide rod; the piston is provided with a one-way air guide structure, the one-way air guide structure including an air guiding channel, the air guiding channel including a circular upper channel and a circular lower channel, and an adjustment ball being arranged inside the upper channel; and purposes of eliminating vibration, lowering noise, eliminating potential safety hazards, being more convenient in assembly and lowering cost are achieved.

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.

A sports exercise area comprising a landing area comprising an impact attenuating system for attenuating impact when landing on the landing area is provided. An impact attenuating system (1; 2) is provided for attenuating impact onto a landing area, for example when exercising freestyle sports, gymnastics or athletics. The impact attenuating system (1) comprises a first inflatable structure (14). The first inflatable structure (14) comprises a first sheet (101) and a sheet (102). A first side (111) of the first sheet is in contact with and connected to a first side (112) of the second sheet along a first plurality of parallel first connection lines (103-1, 103-2, 103-2) to form a first plurality (104) of parallel first air chambers (104-1, 104-2, 104-3). The first plurality of parallel first air chambers is inflatable to form a first plurality of parallel first tubular airbags arranged side-by-side in a first plane substantially parallel to the top surface of the landing area. A top layer (110) may be provided. A second inflatable structure (24) may be provided on top of the first inflatable structure (14).

A person support apparatus includes a support surface having a patient facing surface and includes a head section, a seat section, and a foot section, the head section and the foot section being rotatable with respect to the seat section. One or more actuators are provided to rotate the head section and the foot section with respect to the seat section. At least one strain gauge is provided proximate the patient facing surface of the support surface to detect a change in pressure against at least one of the head section and the foot section. A controller is configured to transmit a signal to one or more of the actuators to rotate a corresponding one of the head section or the foot section in response to receiving data from the at least one strain gauge indicating a change in pressure that exceeds a predetermined reduction in pressure.

Aspects provide a punching bag formed by a body panel with a first edge joined at one edge to form a first closed end, and a second edge distal to the first that defines a second opened end of an interior enclosure of the punching bag that is bounded within interior surface sidewalls of the body panel between the first closed end and the second opened end. The first closed end traps air within the interior enclosure that is configured to interact via the second opened end with ambient air within an outer area surrounding the body panel, to thereby slow motion of the punching bag as it is conveyed through the ambient air in response to forces imparted to the bag body panel by a user.

A ball game apparatus including a centerpiece apparatus member having an outer frame member, an inner frame member, and a raised platform surface disposed within the inner frame member, a plurality of shaped members coupled between the outer and inner frame members, and a ball member configured to bounce off the raised platform surface and the plurality of shaped members.

A pitch board game includes a board made of drop stitch inflatable material. The board, prior to inflation, is light weight, compact and easily carried from location to location. When inflated, the board is comparable in strength and hardness to solid wooden board. The game itself is played like the game “cornhole,” as bean bags are tossed by players onto the upper surface of the board, which is propped up at an acute angle. Bags landing on the surface count one point, and bags landing in a hole in the board count three points.

An inflatable structure with a bottom portion capable of allowing the device to float in a body of water. A vertical tower structure extends upwards away from the bottom portion. Several arms extend away from the top of the vertical tower structure, each ending in an anchor point for receiving a string. At the end of each string is a tossable object. A goal is affixed to the side of the vertical tower structure corresponding with each tossable object. The purpose of the game is to toss the tossable object towards the goal and to hook the ring onto the hook or place the ball within the basket. The entire bottom portion, vertical tower, and arms are made of a single inflatable structure which can be deflated and stored or transported, and inflated to float in the body of water. Drink holders could be contained within the bottom portion.

Embodiments of the invention are directed to devices and methods for providing extension and flexion assistance. A device manipulates a foot of a user, thereby providing extension or flexion assistance to an ankle of the user, and includes a footplate positioned at a pre-determined distance from the user and adapted to pivot about an axis defined by the ankle as the foot extends or flexes about the ankle; and a force application system comprising a force applicator connected to the footplate, and a force application mechanism, wherein the force application mechanism is configured to apply a force to the force applicator, thereby providing the extension or flexion assistance to the foot about the ankle.

An instep weighting training accessory to be releasably fastened around the instep of a shoe having studs or cleats on its sole is provided. The accessory includes a strip, a weight and a layer of padding material. The strip includes an inner layer intended to be in contact the shoe and a sheath to be arranged on the instep of the shoe. The weight is enclosed inside the sheath and the padding material is located between the weight and the inner layer of the strip. In an alternative, an instep weighting training set having a plurality of training accessories is provided.
