[0007]

In the case of FIG. 1, when the shutter s runs on the guide rail, the support of the shutter presses the shielding plates 6 and 6 'of the guide groove 3 in the direction of the arrow. The shutters cause the shielding plates 6, 6 'to slide in the direction of the arrow against the spring pressure of the lower hinges 11, 11', thereby opening the guide grooves. When the shutter s is opened and the guide groove 3 is opened, as shown in FIG.
6 ′ is a spring 13, 1 attached to the lower hinge 11, 11 ′.
The shielding plates 6, 6 'are pushed back in the direction of the arrow by the elastic repulsion action of 3' to close the guide groove, and the shielding plates 6, 6 'are joined at the center of the guide groove, and are not opened by the spring action. FIGS. 3 and 4 show that when the shielding plate 17 is slidably attached to the upper hinge 15 and the lower hinge 16 on the lower surface of one side frame of the guide groove, the shielding plate is opened rightward in the drawing by the entrance of the shutter s. When the guide groove is opened, the upper hinge 15
The shield plate slides to the left by the action of the spring 20 of the lower hinge 16 connected to the guide groove to shield the guide groove. The shielding plate with the guide groove 3 closed is supported by the lower U-shaped plate 4, so that the safety of traffic by the shielding is maintained.

[0008]

According to the present invention, a guide groove is formed by a U-shaped plate through a spring action of a swinging plate connected to an upper and lower hinge mechanism provided in a guide rail frame provided with the above-mentioned sliding shielding plate on the floor surface. This is a hinge mechanism that slides open and close the shield plate to the left and right, and shows the shielding action of the guide groove of the guide rail by the running action of the shutter and the spring action of the hinge mechanism. It is valid.
