Document Type and Number:
WIPO Patent Application WO/2022/139371
Kind Code:
A1
Abstract:
The present invention relates to a one-way fastener. To this end, the present invention relates to a one-way fastener provided to be inserted and coupled toward a through-hole provided in a fixed body from an open outer portion toward a closed inner portion. The fastener is provided such that a deformable sleeve and a pressing sleeve are fitted onto a fastener body, is provided such that a pressing ring is fitted onto the fastener body exposed through the pressing sleeve, and is characterized in that a pressing member is screw-coupled to the fastener body exposed through the pressing ring. Accordingly, when any one surface from among the respective side surfaces of a fixed body is located in a closed space and thus it becomes impossible to couple a bolt and a nut, the present invention can easily be fixed from an open surface of the fixed body toward a closed space surface.
