Abstract

A trampoline assembly (10) comprises a trampoline bed (12); a trampoline frame (14) that supports the trampoline bed (12); and a plurality of spaced apart, resilient members (16) that are attached to and extend substantially between the trampoline bed (12) and the trampoline frame (14) to maintain the trampoline bed (12) in tension. At least one of the resilient members (16) is an adjustable resilient member (216) that can be selectively adjusted while simultaneously connected to both the trampoline frame (14) and the trampoline bed (12) to selectively adjust the tension of the trampoline bed (12). The adjustable resilient member (216) includes a resilient assembly (218); a first connector (220) that is movably connected to the resilient assembly (218); and a second connector (222) that is movably connected to the resilient assembly (218). The resilient assembly (218) is rotatable in a first rotational direction to increase the tension of the trampoline bed (12), and in a second rotational direction to decrease the tension of the trampoline bed (12).

Dependent claims

A trampoline assembly comprising:

a trampoline bed;
a trampoline frame that supports the trampoline bed;
and
a plurality of spaced apart, resilient members that are attached to and extend substantially between the trampoline bed and the trampoline frame to maintain the trampoline bed in tension, wherein at least one of the plurality of spaced apart, resilient members is an adjustable resilient member that can be selectively adjusted while simultaneously connected to both the trampoline frame and the trampoline bed to selectively adjust the tension of the trampoline bed;
and wherein the adjustable resilient member includes a resilient assembly, wherein the resilient assembly includes a single spring, a first plug that is fixedly secured to the single spring, and a second plug that is fixedly secured to the single spring, the second plug being spaced apart from the first plug, a first connector that connects the resilient assembly to the trampoline bed, the first connector including a first externally threaded surface that is threaded into the first plug, and a second connector that connects the resilient assembly to the trampoline frame, the second connector including a second externally threaded surface that is threaded into the second plug, wherein threads of the first externally threaded surface are opposite from threads of the second externally threaded surface such that one of the first externally threaded surface and the second externally threaded surface includes right-hand threads and the other of the first externally threaded surface and the second externally threaded surface includes left-hand threads;
wherein the resilient assembly is rotatable (i) in a first rotational direction relative to the first connector and the second connector while the adjustable resilient member is simultaneously connected to both the trampoline frame and the trampoline bed to increase the tension of the trampoline bed, and (ii) in a second rotational direction relative to the first connector and the second connector while the adjustable resilient member is simultaneously connected to both the trampoline frame and the trampoline bed to decrease the tension of the trampoline bed;
wherein threads of the first externally threaded surface have a differently spaced pitch than threads of the second externally threaded surface.
