Claims (1)

[Scope of utility model registration request] A pair of left and right support frames 2, 2 arranged in parallel, a footboard 3 horizontally suspended between them at a predetermined interval along the longitudinal direction and at a predetermined inclination angle, and the left and right support frames 2, 2. A pair of left and right lid plates 91 are provided that can be opened and closed via a hinge 8, and a bracket 13 is provided that projects from the upper surface of the support frames 2, 2 and has a stopper 15 projecting from its inner surface. 1
3, a stopper pin 20 provided facing an opening 9b formed at a position facing the stopper 15 of the lids 9, 9, and one of the pair of lids 9 facing each other. Equipped with a locking mechanism 22 provided on the lid side, □
The stopper 15 has an arcuate portion 15a formed from its tip to the upper surface, and an inclined surface 1 that gradually becomes lower from the top of the arcuate portion 15a toward the bracket 13 side.
5b, the stopper pin 20 has a warhead-shaped tip and is pressed by a spring 21 in the direction of engagement with the stopper 15, and the locking mechanism 22 has a top plate of one lid 9. It has a lock lever 23 slidably supported in a direction across the lid 9 by a guide plate 24 projecting from the lower surface of the lock lever 9a, and a pin 25 projecting perpendicularly to the lock lever 23. And this pin 25
is fitted into a linear guide groove 9C corresponding to the lock lever 23 formed on the top plate 9a and faces above the top plate 9a, and both ends of the guide groove 9C are perpendicular thereto and They are connected to the circular holes 9e through grooves 9d that are continuously formed in the direction away from the longitudinal edge of the lid 9, and rise up while crossing the continuous part of the circular holes 9e and 9d. A substantially L-shaped stopper 28°28 is provided, the upper end of which is fixed to the lower surface of the top plate 9a, and the tip of the horizontal part is fixed to the reinforcing member 29 side, and the protruding length of the pin 25 is one lot. This protrusion length is 9 greater than the distance between the flavor 23 and the stopper 28, and has a protrusion length such that the upper end does not protrude from the upper surface plate 9a when it is rotated and accommodated in the circular hole 9e. A guide plate 24 having a through hole into which its tip fits is fixed on the same axis as the lock lever 23 on the side of the lid body 9 opposite to the side where the lock mechanism 22 is provided, and the guide plate 24 has a guide plate 24 having a through hole into which the tip thereof fits. The pin 2 is attached to the inner end of 9C.
5, the tip of the lock lever 23 is in a position slightly retracted from the edge of the lid body 9 on the side where the lock lever 23 is provided, and the pin 25 and the guide groove 9C are in the outer end culm. A ship gangway characterized in that, when the lock lever 23 is positioned, the tip of the lock lever 23 is fitted into the through hole of the guide plate 24 of the opposing lid 9.
