Description

[Brief explanation of the drawing]

Figure 1 is an elevation view showing an example of the proposed telescoping door, Figure 2
Figures 6 to 6 are enlarged cut-away end views showing the pin joints of the telescoping door of the present invention, Fig. 7 is an elevational view showing another example of the telescoping door of the invention, and Fig. 8 is an elevational view of a conventional telescoping door. In the figure, 1 represents a diagonal member, 3 a lattice frame, 4 a pin shaft, and 5 a slide groove.

Claims (1)

[Scope of utility model registration request] The intersection points of the diagonal members tilted in opposite directions at the front and rear positions are pivotally connected, a lattice frame is provided at the intersection of the front and rear diagonal members, and one pin shaft that pivotally supports the diagonal members is connected to the front and rear. In an extendable door that protrudes outward and is fixed to the lattice frame, and has other pin shafts located in the vertical direction that protrude back and forth and fit into the sliding groove of the lattice frame so as to be vertically movable, the lower end of the diagonal member A telescoping door characterized in that pin shafts located at the lattice frames on both sides are fixed to the lattice frames on both sides, and pin shafts located at the upper end of the diagonal member or at the upper and lower middle parts are fixed to the lattice frames other than on both sides.
