A recreational slide system is provided. The recreational slide system includes a slide and a ride vehicle configured to support a rider down the slide. The slide includes a slide body with a non-wet lubricated slide surface that extends between a top entrance of the slide and a bottom exit of the slide. The ride vehicle includes a fabric layer that forms a top surface configured to contact the rider and a mesh layer that forms a bottom surface configured to contact the slide surface. The coefficient of friction between the mesh layer of the ride vehicle and the non-wet lubricated slide surface is within a range of between about 0.03 to about 0.2.

The present invention relates to a unit block having a coupling portion and an insertion portion provided in special structure and shape such that, instead of providing an assembly-type toy that makes a user build an assembly-type completed product according to the manual, the user is enabled to implement various articles by exercising creativity without feeling bored. The present invention provides a unit block, which has integrally provided coupling and insertion portions, and provides, as a means for using the same when a desired object is to be implemented.

A water slide includes a blind tube portion having a blind tube opening on a front end of the blind tube portion that is adjacent to the tubular slide portion of the water slide. The opening is closed by a transparent peripheral wall segment of the tubular slide portion, which extends in the sliding direction as well as in the peripheral direction of the tubular slide portion. The transparent peripheral wall segment may be curved in the peripheral direction and preferably fits into the shape of the tubular slide portion. Like the tubular slide portion, the blind tube portion may include a peripheral wall, for example, being closed on the periphery. The blind tube portion may include a dead end. The longitudinal extent of the blind tube portion is preferably much shorter than that of the tubular slide portion.

A convertible furniture and toy assembly for children, which has a symmetrical base unit and replaceable module elements that can be attached thereto. The base unit contains two side units arranged at an equal distance from its plane of symmetry and at least two connecting elements connecting the two side units. The convertible furniture and toy assembly for children is provided with a stabilizing system in which the side unit of the base unit contains a first side element, a second side element, and an intermediate side element connecting them. The first side element is arranged at a predetermined distance X and the second side element is arranged at a predetermined distance X+Y+V from the plane of symmetry. The stabilizing system preferably also contains at least one connecting member and module elements that can be installed symmetrically on the base unit.

In various representative aspects, a modular play structure is created using multi-piece connectors and rod members and their connecting elements. The multi-piece connector for facilitating the construction of a modular amusement play structure herein includes a first piece defining a tubular connection member having a first end, the first end adapted for abutting connection, a second piece defining a tubular connection member having a first end, the first end adapted for abutting connection with the first piece and an inner connection member sized and shaped to fit within the first and second pieces. The inner connection member being expandable and including releasable locking members interconnecting with the inner connection member adapted for expanding the inner connection member and reversing the same.

A material joint connecting an internal spar or baffle to panel walls of inflatable structures. The material joint is formed by a folded center strip and a pair of side strips. The side edges of the center strip are folded to form an initial T-shaped cross-section having a middle section, two side sections formed by a first bend, and two overlapping end sections formed by a second bend. The middle section is fused directly to the facing surface of the panel wall and the overlapping end sections are fused together to extend perpendicularly from the middle section. The end strips overlap the center strip with part of the end strips fused to the side sections of the center strip and part fused directly to the panel wall. The spar or baffle is connected to the fused overlapping end sections of the center strip. Under the internal air pressure of the inflated structure, the side sections bow and arc under tension from the connected spar or baffle and the middle section acts as a bridge to lift and flatten the exterior surface of the panel wall across its width.
