Claims

[Scope of utility model registration request]

The upper and lower lattice bodies arranged between the left and right frames movable along the upper and lower rails are made up of a front telescoping rod and a rear telescoping rod that is in an inconsistency with the front telescoping rod, which are pivoted at the intersection. Both ends of the rear telescoping rod and both ends of the front telescoping rod in the lower lattice body are pivotally connected to fixing pieces provided at the upper and lower inner ends of the left and right frames, and both ends of the front telescoping rod in the upper lattice body Sliding pieces to which both ends of the front telescoping rod of the lower lattice body are pivoted face the inner middle parts of the left and right frames, and furthermore, the interlocking shafts fixed to the sliding pieces on one side of the upper lattice body and the outside of the one side frame face. Compression springs are interposed between the lower fixed shafts, and between the interlocking shaft fixed to the sliding piece on one side of the lower grid body and the fixed shaft on the outside upper part of the one side frame body, and are operated from the room. An automatic opening type surface grating characterized by interlocking elastic stoppers facing the inner ends of the left and right frames.
