Abstract

PROBLEM TO BE SOLVED: To prevent a projection to a floor panel, allow permanent installation without causing any obstruction, enable characters, marks or the like to be delineated on the upper surface of a part on a cross rail, and improve appearance even in terms of design by forming a part of a cover for closing a floor panel opening at a high position and extending a cross rail type rope suspension member to the opening. SOLUTION: In an ordinary case where an opening 2 is not used, the opening 2 is closed by placing a cover 6 and a rope suspension member 4 on the stepped part 3a of a cover receiving frame 3. In this state, the upper surface of the rope suspension member 4 becomes flush with the cover 6, and functions as the cover 6 for closing the opening 2. For access from a high level floor panel 1 to a lower facility or vice versa via the opening 2, the cover 6 is detached and the rope suspension member 4 is moved, for example, to such a place as not hindering a work. The rope suspension member 4 can be dislocated via a slide motion on the periphery of the opening 2 along the stepped part 3a. In this case, the rope suspension member 4 horizontally slides along the periphery of the opening 2, with a fall preventive board kept in contact with the vertical surface of the cover receiving frame 3, thereby ensuring freedom from a concern about a fall.

According to the present invention, in order to achieve the above-mentioned object, a horizontal rail-shaped rope hanging member spans the opening as a part of a lid for closing a high-floor floor plate opening. The horizontal rail-shaped rope hanging member is slidably locked to a locking step formed inside the opening, and a slide-prevention plate is provided at both ends to abut against a side wall in the opening. The gist is that the upper edge is chamfered.

According to the first aspect of the present invention, the hanging jig is formed as a part of the lid that closes the opening by forming the hanging jig with a horizontal bar-shaped rope hanging member, so that the hanging jig is projected on the floor plate. Without
Permanent installation does not get in the way. In addition, characters, marks, and the like can be freely drawn on the upper surface of the horizontal rail-shaped member, and an aesthetic appearance can be obtained in design.

According to the second aspect of the present invention, in addition to the above-mentioned operation, the horizontal rail-shaped rope hanging member can be moved to an arbitrary position within the opening so as not to be a hindrance when ascending or descending or unloading. it can. Such movement is performed along the locking step formed inside the opening, so that the sliding can be performed smoothly. Then, when moving by sliding or the like, since the slip-down prevention plate is in contact with the side wall in the opening, the drop of the rope hanging member can be prevented.

According to the third aspect of the present invention, in addition to the above operation, since the upper end edge in the length direction of the rope hanging member is chamfered, the rope can be smoothly hung therefrom.
