Title:
SAFE TRAMPOLINE
Document Type and Number:
WIPO Patent Application WO/2015/030510
Kind Code:
A1
Abstract:
The present invention relates to a safe trampoline using a connection member such as a wire and a rotatable member such as a bearing. The trampoline according to the present invention comprises an elastic mat and a support frame, the support frame consisting of an upper frame formed at least around the elastic mat and a lower frame for supporting the upper frame. The trampoline according to the present invention further comprises: a plurality of rollers mounted on the upper frame; connection members, except for a spring, one side of each of which is directly or indirectly coupled to the peripheral part of the elastic mat and the other side of each of which is at least partially wound around each of the plurality of rollers; and elastic bodies, one side of each of which is coupled to the other side of each of the connection members and the other side of each of which is fixedly coupled to a certain portion of a lower plane of the elastic mat so that the elastic body is configured to be elongated or restored to the original state thereof according to the load applied to the elastic mat. The trampoline according to the present invention can minimize the space between the elastic mat and the frame, thereby maximizing the usable space. Also, since there is no spring tension space which is a risk factor, the trampoline is effective in preventing the occurrence of safety accidents, which are a major problem of conventional trampolines.
