A swing assembly is configured for shared enjoyment by a person and a dog. A swing seat may include a framework and a surface material that provides a desired combination of slip resistance and softness. The swing seat may be suspended from first and second support posts positioned to the sides of the swing seat, thereby reducing side-to-side rocking of the swing seat. One or more tether elements may limit the movement of the swing seat in the swinging direction and optionally help reduce side-to-side rocking of the swing seat, such that the swing seat has an appropriate level of stability for a dog during use.

The present invention comprises a restrainer of relative motion among chain links which generally consisting of fastening arrangement installed on multiple links. In order for the desired restraint to occur, the chain must be straight in order for the two elements to be aligned with each other. Then, the first link in the chain is rotated around its vertical axis so the protuberant part enters in the groove which causes the movement to be restrained.

A chain link for a link chain has two legs running parallel to one another, and connected to one another at the ends via curves. The legs and curves are circular in cross-sections. The legs have smaller cross-sectional areas compared to the cross-sectional areas of the curves. The chain link is manufactured by radial forging with: providing a profile bar, and the profile bar is made of a steel material, inserting the profile bar into a radial forging machine and radial forging with reduction of the diameter of the profile bar in longitudinal portions, so that the profile bar is axially stretched in the forged longitudinal portion, wherein the diameter is reduced at least in the region of the later legs, and removing the radially forged chain link semi-finished product and forming the profile bar into a chain link as well as welding the front ends of the formed chain link.

A chain marker comprising: a first body portion having an aperture, a first end and a second opposing end, wherein each of the first and second ends has a recess for receiving at least a portion of a first link of a chain; a second body portion having an aperture and first and second ends, wherein each of the first and second ends has a recess for receiving at least a portion of the first link, wherein the chain marker is adapted such that, in use, the first and second body portions may be brought together such that the apertures of the first and second body portions are aligned for receiving a fastener and the recesses of the first and second ends are aligned such that the first and second body portions encompass at least a portion of the circumference of a straight portion of the first link such that the chain marker is held in position within the aperture of the first link.
