A slide system has a base inflatable structure capable of sustaining an air pressure, and a slide surface supported by the base inflatable structure. A lower slide flap forms a bottom end of the slide surface, and a lower slide support of the base inflatable structure supports the lower slide flap. A bumper body receives air pressure from the base inflatable structure to inflate to form a protrusion that extends upwardly from the lower slide support when inflated. A restraint structure restrains the bumper body to a flattened configuration, but when the restraint structure is released, the bumper body inflates to form the protrusion that forms a bumper at the bottom of the slide.

An obstacle apparatus is disclosed for an individual to traverse. The obstacle apparatus comprises a chassis and a frame. A hinge pivotably couples the chassis and the frame for positioning the frame in an inclined orientation relative to the chassis. A first drum is rotatably coupled to the frame. A second drum is rotatably coupled to the frame. A belt encircles the first drum and the second drum for defining a continuous loop belt system. A drive engages the continuous loop belt system for creating a displacement in the belt. The belt defines an upper belt surface for the individual to traverse.

A locking carabiner includes a body having a first end and a second end. A gate rotatably coupled to the second end about a gate axis, and a locking mechanism rotatably coupled to the gate about a locking mechanism axis. The locking member is configured to engage with the first end, and the gate axis is substantially parallel to, and offset from, the locking mechanism axis. Additionally, the rotation of the locking mechanism is in a substantially similar plane as the rotation of the gate.

The multifunctional device has slide and ladder portions easily connectable for use together as a self-supporting unit, and easily detachable for use separately on other equipment or for compact storage or transport. When set-up for use as a self-supporting unit, the ladder and slide portions are hooked together by a double-hook/double-axle connection system that does not allow the angle between the ladder and slide to change any significant amount during normal use of the set-up device. Yet, quick disconnection may be done when the weight of the user is removed, by purposely lifting and pivoting the portions, and then unhooking their top ends from each other. When disconnected from each other, the ladder and/or the slide portion (and preferably both) may be connected/hooked to another object(s), for example, a trampoline or a play equipment platform or other specially-adapted elevated structure, for climbing up to, and sliding down from, said trampoline/platform.

A jungle gym joint has a joint main body including joint shafts to which pipes are connected and rotary members. The pipe is connected to one end and a folding portion is formed at the other end of the rotary member, the folding member being formed by a flat plate portion being held in a bifurcate portion together with the joint main body. A cover member including engaging projections on an inner circumferential surface is provided on an outer circumference of the folding portion. The cover member is guided to move back and forth in an axial direction by the engaging projections being brought into engagement with guide grooves. The folding portion is restricted from being folded with the cover member staying in an advanced end position while the restriction of folding thereof can be released with the cover member staying in a withdrawal end position.

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 unit block coupling means comprising: a unit block coupling portion, which has an insertion portion sized to be fitted into the coupling portion and narrowed by a degree corresponding to the outer wall of the coupling portion at the upper end of the coupling portion, thereby being integrated therewith, wherein circular penetration/coupling holes are formed on fourth side surfaces of the insertion portion, and partial tube extension portions are formed on the upper/lower/left/right sides of the penetration/coupling holes; the unit block is structured to have a -shaped inner extension concave groove at the center of the surface of the coupling portion; when vertically coupled to a different unit block, a -shaped support piece is fitted and coupled to the -shaped inner extension concave groove formed on the surface of the coupling portion; when horizontally coupled to a different unit block, partial protrusion portions, which are formed on the surface of a support shaft, are fitted to the partial tube extension portions formed in the penetration/coupling holes of the coupling portion; and the unit block coupling means is applied to secure a high degree of coupling force.
