An inflatable device designed as a martial arts training and/or educational device. The inflatable device includes an inflatable structure and at least one interactive device connected to the inflatable structure. The inflatable structure includes a floor that is at least partially inflatable, a plurality of inflatable columns extending upwardly from the floor and a plurality of inflatable beams connected to a top or top portion of the columns. The at least one interactive device includes a target, an inflatable target, punching or kicking target, inflatable punching or kicking target, an object in the form of a person or ninja, an inflatable in the form of person or ninja, an object in the form of a person or ninja with a target, and/or an inflatable in the form of a person or ninja with a target.

A safety airbag device for cushioning the free fall of a person or object from an elevated height. The airbag device includes an inflatable base bag capable of sustaining an air pressure and an inflatable structure coupled to the base bag, where the inflatable structure is in air communication with the base bag. A net is coupled to a top portion of the inflatable structure for decelerating and supporting the individual from free fall. A top cover is coupled to the base bag that substantially encloses the inflatable structure.

Systems, methods, and devices for protecting a user head are provided. In one example, a computer-implemented method can comprise receiving, by a system operatively coupled to a processor, a set of data detected by one or more sensor embedded within the helmet device. The computer-implemented method can also comprise adjusting, by the system, a pressure condition within a first set of inflatable cells of the helmet device based on the set of data.

An exercise device and an inflatable alternative are provided. The exercise device is composed of a planar base attached to block(s). The block(s) may serve as cushioning or weighted items to enable a variety of exercises. The planar base is securable against a structure such as a door frame. The planar base is also convertible to a bench with shaft(s) that connect block(s) to form legs for the bench. The inflatable alternative includes a top end that is securable to the structure. A bottom end of the inflatable alternative is securable to a user through an ankle cuff. The ankle cuff provides the user a measure of control over a mobility of the inflatable alternative during an exercise.

A dance training device, including: a training unit; a measuring unit; and a connection rod. The training unit is connected to the measuring unit via the connection rod. The training unit includes a base, an elastic balancing plate, and a self-balancing airbag disposed between the elastic balancing plate and the base. The base includes an upper surface and a balancing trough disposed on the upper surface. The self-balancing airbag is located in the balancing trough. The measuring unit includes a first support frame, a second support frame, a third support frame, self-balancing universal wheel assemblies, and an angle measurement instrument. The second support frame and the third support frame are vertically disposed relative to the ground, and each includes a first end and a second end. Two ends of the first support frame are joined to the first ends of the second support frame and the third support frame, respectively.

An open field game arrangement includes glowing targets and provides responses, such as lights and sounds, when the targets are hit.

A trampoline comprising a trampoline frame having legs. The trampoline frame has a trampoline frame horizontal portion. A trampoline bed is suspended across the trampoline frame horizontal portion. Springs extend between the trampoline frame and trampoline bed. An enclosure is connected to the trampoline frame. The enclosure has an enclosure upper support. The enclosure supports an enclosure net. A pad system covers the springs. The pad system includes a wall pad extending upwardly from the springs and terminating at a pad system apex. The pad system further includes a buttress pad connected to the pad system apex at an apex angle from the wall pad, which is defined as an angle between a wall pad outside surface and the buttress pad. The buttress pad extends downwardly to cover at least partially the trampoline frame horizontal portion.

A bouncy castle grounding assembly for discharging static electricity from a bounce house includes a bounce house which has an inflation tube for inflating the bounce house. A fan is fluidly attachable to the inflation tube to blow air into the bounce house for inflating the bounce house. A grounding band is positionable around the inflation tube and the grounding band is comprised of an electrically conductive material. In this way the grounding band to be in electrical communication with the bounce house. A ground wire is attachable to the grounding band such that the ground wire is in electrical communication with the inflation tube when the grounding band is positioned around the inflation tube. The ground wire is attachable to a ground to discharge static electricity from the bounce house.

An exercise system is provided for enabling a user to perform therewith a modified plank exercise, the exercise system includes: a top element having an interface for the user to hold or rest thereon; and a bottom element having an interface with a ground surface, the top and bottom elements interconnected and separated from each other with a middle element. At least one of the top and bottom elements is interchangeably coupled to the middle element, and the exercise system includes at least one element of instability that is overcome by involving core muscles of the user.

The present disclosure provides a human-powered entertainment device. The entertainment device includes an inflatable base and a paddling component which is connected with the inflatable base, wherein the paddling component is adapted to swing when a force is imposed thereon, so as to perform paddling in water to make the human-powered entertainment device move on water. Accordingly, the entertainment device of the present disclosure can be driven to move and low in cost.
