Title:
SPIRAL STRUCTURE
Document Type and Number:
Japanese Patent JP3484295
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To eliminate also a bond state simply by strongly bonding mutual bodies together using spiral bodies, to enable a prescribed twist on the basis of an environmental change, to keep the size of meshes constant, and to facilitate repair.
SOLUTION: Spiral bodies 1, 3 are formed by winding a wire rod with a prescribed diameter, in a spiral diameter twice as large as the diameter, in a shape in which a thread part faces a bottom part, each bottom part agrees with the centers of the bodies 1, 3, at a prescribed lead, pitch, in a prescribed direction. To a fixed block 11 fixed to one body 7 to be bonded, being supported movably, a restriction member 13 is moved backward, to a space between mutual bodies of each spiral body 1 of the open block 11, each spiral body 3 attached to the other body 9 to be bonded is engaged so that the thread parts of and the bottom parts of the spiral body 1 are put together with the thread parts and the bottom parts of the spiral body 3, respectively. In this state, when the member 13 is slide-operated to cover the upper surface of the block 11, the contact part of the member 13 contacts and restricts the upper parts of the bodies 1, 3 engaging with each other.
