摘要： An adjustable knock-down type pool side trapeze fixture is made up of a base with spaced parallel side structures each having a telescoping main column extending obliquely upwardly and outwardly over the pool. A trapeze sling is suspended from the tops of the main columns. A stiff brace extends rearwardly from a forward end of each side of the base and is anchored to the respective main column, the columns also serving as mountings for adjustable rings and the braces being employed as a platform by the user for starting a trapeze swing. Guy lines from the main column to the base complete the bracing.
