A recreational structure, such as a trampoline frame, can be quickly and reliably assembled using a sleeve-joint coupling having a “T” configuration. A first arm member and an aperture that is formed in the sleeve-joint coupling are disposed in an opposite relationship. A second arm member and a third arm member are disposed in an opposite relationship with each other. The first arm member receives one end of a vertical frame member of the recreational structure, while the aperture receives one end of a vertical pole member of, for example, a safety enclosure. The second and third arm members each receive one end of a horizontal frame member of the recreational structure. A tension member applies a force between a vertical frame member and a corresponding vertical pole member that compresses the vertical frame member toward the corresponding vertical pole member.

The invention relates to a removable bolt assembly for fastening a toilet seat to a commode using a knob or bar handle. The knob or bar handle, pivotally mounted to the bolt, can be used to twist or clamp the bolt into engagement with a nut that is inserted through a hole in the toilet. The hole in the toilet can be circular or noncircular. Where the hole is noncircular, the nut has a corresponding noncircular geometric neck so as to prevent it from rotating in the hole. Where the hole is circular, a fastening hinge having a connecting insert can be used to prevent rotation of the nut when it is engaged with the connecting insert. In this way the bolt is directly interlocked with the nut without the use of any tool, thereby making it easy to lock and fasten the seat to the commode.

A cooling channel cover for a one-piece piston of an internal combustion engine, the piston having a closed cooling channel that runs around inside the piston crown, at the level of the piston ring band, and a ring-shaped recess provided between the piston ring band and the piston shaft. The piston shaft is connected with the piston hubs suspended on the piston crown. In such a piston, an easy to assemble cooling channel cover is achieved by a one-piece plastic / spring steel ring that is U-shaped in cross-section, having a ring bottom and an outer shank around the circumference, molded onto the ring bottom and angled off radially to the outside, and an inner shank around the circumference, angled off radially to the inside. The plastic ring has a first radial division having a mouth width and a second radial division, opposite the first division, which does not separate the radially angled outer shank that runs around the circumference, to form a film hinge for radial deflection of a ring shank formed by the film hinge.

A belt band conveyor has an endless conveyor belt band guided over deflection and / or drive friction rollers, for deflecting and / or driving the conveyor belt band. Each roller includes an axially-extending shaft. At least three roller segments are releasably mounted on the shaft, axially apart from one another, so as to rotate about a rotational axis extending axially in the longitudinal direction, Each roller segment has an inside circumference contour and a friction surface on its radial outside circumference engaging on the lower belt with friction fit. The inside circumference contour of each roller segment and the outside circumference contour of the shaft are structured so that each roller segment is connected with the shaft with shape fit to prevent twisting about the rotational axis. When the shaft turns about the rotational axis, in a rotational direction, the roller segments also turn about the rotational axis, in this rotational direction.
