A water play structure (100) includes a frame base (102), a telescoping hollow frame column (112) supported in a vertical orientation and stabilized by the frame base, and a plurality of frame arms (110, 118). Each frame arm extends horizontally radially outward from, and mounted to, one of the frame base or the telescoping hollow frame column. An outward distal end of a first frame arm includes a first interface structure, and each water play station (108, 202), selected from a plurality of different water play stations, includes a second interface structure. The first interface structure and the second interface structure are standardized mutually compatible interface structures which allow different water play stations to be coupled to, and used with, each frame arm in a modular implementation.

A stair and slide assembly includes a stair portion including a plurality of stairs, a slide portion including a slide with an entrance and an exit, and an assist bar positioned proximate the exit of the slide to assist a user with pivoting from the exit of the slide to the stair portion. The slide has a first portion extending substantially linearly from the entrance of the slide at an angle and a second portion extending from the first portion to the exit of the slide. The second portion transitions the slide from the angle of the first portion to substantially horizontal. The exit of the slide is configured to be positioned at a target height above a ground surface. The target height is between about 18 inches and about 30 inches.

An amusement ride providing the sensation of riding scissor lift construction equipment to ride passengers is disclosed. The amusement ride has a scissor lift mechanism supported by a construction equipment frame with wheels thereon. A stationary support structure supports the equipment frame and suspends the wheels in midair to hold the equipment stationary. A cargo lift platform connected on top of the scissor lift mechanism has amusement ride seats mounted thereon. The ride seats have passenger restraints which provides amusement-ride-level safety. An electric motor drivingly connected to the scissor lift mechanism is operated by a ride operator to raise and lower the cargo lift platform. A passenger access platform situated adjacent the cargo lift platform allows ride passengers to easily and safely enter and exit the scissor lift.

A stair and slide assembly includes a stair portion including a plurality of stairs, a slide portion including a slide with an entrance and an exit, and an assist bar positioned proximate the exit of the slide to assist a user with pivoting from the exit of the slide to the stair portion. The slide has a first portion extending substantially linearly from the entrance of the slide at an angle and a second portion extending from the first portion to the exit of the slide. The second portion transitions the slide from the angle of the first portion to substantially horizontal. The exit of the slide is configured to be positioned at a target height above a ground surface. The target height is between about 18 inches and about 30 inches.

A modular observation assembly and method of use are presented herein. The assembly includes a portable base member that can roll along the ground. The base member defines an interior volume used for storage of various members and portions of the assembly. The assembly also includes an elevating platform in communication with the base member. The elevating platform operates between a lowered position and an elevated position. The assembly is stabilized by one or more jacks and a hitch attachment assembly configured to secure the base member to the neighboring vehicle.

A portable, folding dog agility teeter is disclosed. The teeter has two boards which are connected by a hinge. A pair of legs are also hinged. Each board can be reversibly fixed in relation to the hinge so the longitudinal axis of each board is parallel to the other. A fulcrum is formed where the legs attach to the hinge. One of the boards is heavier than the other so the heavier board is touching the ground when no additional load is on the other board. As a dog crosses from one board to the other, the teeter moves so the lighter board touches the ground. When the dog leaves the teeter the heavier board moves to touch the ground, thereby resetting the teeter for repeated use.

An amusement device attached to a flat bed surface of a flatbed truck. A subfloor is hingedly attached to one end of the flat bed. A mechanical assembly such as a telescoping hydraulic rod can be extended or retracted by an operator to change the angle of the subfloor. A plurality of flat panels unfold to form a circularly shaped main floor. The floor includes a central shaft that can be activated to cause the floor to rotate. People holding carriages are round in plan view and have castor support wheels cause the carriage to slide around on the circular shaped floor as the floor both rotates and is tilted at an angle. The centrifugal force of the rotation causes the carriages to be flung outwards where the are retained by a scalloped perimeter wall attached to the circular floor.

Mobile obstacle courses include an expandable structure that is supported by a wheeled chassis and contains a plurality of obstacles therein. The expandable structure is configured to move between a transport state and a deployed state and includes: a central obstacle area and an outer obstacle area that is connected to the central obstacle area in the transport state and in the deployed state. In the transport state, the expandable structure has a first footprint. In the deployed state, the expandable structure has a second footprint that is larger than the first footprint.
