Title:
STRUCTURE FOR FIXING FLOOR PLATE TO FLOOR PLATE FRAME
Document Type and Number:
Japanese Patent JP3078904
Kind Code:
B2
Abstract:
PURPOSE: To make it possible to open a floor plate by more than 90° and to prevent quick closing of floor plate in the way of closing operation.
CONSTITUTION: A shaft holding hole 5 is made in the vicinity of one end in the longitudinal direction of a pair of opposing side frame parts 2 of a floor plate frame 1. The shaft holding hole 5 comprises a hole 3 inclining downward toward the front end and a lateral hole 4 horizontally continuous from the rear end of the inclined hole 3 toward the rear. Shafts 7 are planted in the vicinity of one end parts on the opposite sides of a floor plate 6. The shafts 7 are fit rotatably and movably in the shaft supporting holes 5 so that the floor plate 6 can rotate by 90° or more with respect to the floor plate frame 1. A spring member 9 exert pressing force resiliently to block rotation of the floor plate 6 under a state where the floor plate 6 has risen by about 90° with respect to the floor plate frame 1.
