Lattice point coupling device, the coupling member and the telescopic lattice tetrahedron of using this

摘要

PROBLEM TO BE SOLVED: To prevent clattering of lattice sash bars by connecting a pair of fitting blades slidingly fitted in a rotatable state into slide grooves, integrally parallel so as to provide a connecting member having a connecting part that can pass through a narrow opening. ;SOLUTION: Fitting blades 5 are inserted in slide grooves 3 from the end parts of lattice sash bars 1 in such a way that connecting shafts to be connecting parts are respectively adjusted to narrow openings. A connecting member 4 is therefore slidingly fitted between a pair of lattice sash bars 1 so as to be rotatable while locking the fitting blades 5 to locking line members 2 so as not to slip off. When one lattice sash bar 1 is rotated in relation to the other lattice sash bar 1 at an intersection point, the connecting member 4 is rotated along with the lattice sash bar 1, and it can be rotated in such a way as to obtain a specified angle of the lattice sash bar in a lattice, and the fitting blades 5 are fitted and drawn into the slide groove of each lattice sash bar 1. As a result, a pair of lattice sash bars 1 are connected in an overlapped state. The lattice sash bars lean therefore be fixed to each other at the intersection point so as to be able to prevent clattering of the lattice sash bars.;COPYRIGHT: (C)1999,JPO
