Title:
LINKING TOOL FOR ARTICLES AND LINKING STRUCTURE USING SAID TOOL
Document Type and Number:
WIPO Patent Application WO/2021/149755
Kind Code:
A1
Abstract:
A linking tool (4) that can be inserted into a hollow part of a designated article (2) is provided with a plurality of segments (11) including fastening parts (11, 21) constituting a body part (41), sealing parts (12, 22) constituting an insertion part (42), and connecting parts (13, 23) constituting a neck part (43). The fastening parts (11, 21) can be displaced between a basic state in which a gap is opened with respect to an inner surface of the hollow part and an active state of adhering firmly to the inner surface of the hollow part. When the fastening parts (11, 12) are in the basic state, the sealing parts (12, 22) can pass through a through-part (3a) of a counterpart article (3), and when the fastening parts (11, 21) are in the active state, the the sealing parts (12, 22) can undergo integrated displacement with the fastening parts (11, 21) so as to be unable to pass through the through-part (3a). The fastening parts (11, 21) are displaced from the basic state to the active state by the operation of an externally operated member (5), so as to link the articles (2, 3) together.
