金具に関する。[Detailed Description of the Invention] This invention relates to a suspension type automatic opening/closing door used for railway vehicle entrances, etc., which is attached to the top surface of the door in order to prevent the suspension type door roller from coming off the rail. This invention relates to a mounting bracket for fixing a retaining piece to a door.

つてしまう。 As shown in Figures 1 and 2, the suspension type automatic opening/closing door used for the entrances and exits of railway vehicles is such that the door 1 is suspended from the rail 4 via two brackets 2 and two door wheels 3, and one By connecting the rod 6 of a pneumatic piston type door engine 5 to the bracket 2, the door 1 can be opened and closed automatically by remote control. In the suspension type automatic opening/closing door constructed in this way, the door roller 3 is connected to the rail 4.
In order to prevent the door from falling off, it is necessary to make the gap between the lower surface of the rail 4 and the upper end of the door 1 as small as possible. For this reason, conventionally, as shown in FIGS. 1 and 2, a roller 7 is provided on the bracket 2 below the rail 4, and the distance d 1 (FIG. 2) between the roller 7 and the lower surface of the rail 4 is By making the wall height h of the side edge portion shorter than the height h of the wall, the door roller 3
was prevented from falling off the rail 4. By the way, in a suspension type automatic opening/closing door, as a result of long-term use, the door roller 3 wears down and the outer diameter of the door roller 3 becomes smaller, causing the entire door 1 to move downward.
Distance d 2 between the lower end of the door 1 and the lower guide rail 8
(Fig. 1) becomes too narrow. For this reason,
If the door wheel 3 is worn out, the bracket 2 to which the door wheel 3 is attached must be moved slightly downward relative to the door 1 and reattached.
Even if the rollers 7 and the lower surface of the rail 4 are reattached, the distance d 1 between the roller 7 and the lower surface of the rail 4 remains widened.
The function of the roller 7 to prevent the door roller 3 from coming off is lost.

因ともなつてしまう。 Therefore, it has been considered to attach a retaining piece for preventing the door roller 3 from falling off, not on the bracket 2 but on the door 1 as a reference. That is, as shown in FIG. 3, a mounting bracket 11 having a block 10 fixed to one side of a vertical flat plate 9 is used. Block 1
A retaining piece 12 made of a slippery material such as synthetic resin or oil-impregnated metal is attached to the bracket 2 with bolts 18 to the bracket 2. The lower edge of the block 10 is brought into contact with the upper end surface of the door 1 to prevent the retaining piece 12 from shifting downward. Rail 4 when installing
To adjust the distance d 1 between the lower surface of the door 1 and the upper surface of the locking piece 12, the lower surface of the block 10 of the mounting bracket 11 is filed down with a file, etc., so that the lower surface of the block 10 is always in contact with the upper surface of the door 1. Do it like this. However, in this way, the block 10 of the mounting bracket 11
Scraping the entire bottom surface of the machine is troublesome and can lead to a decrease in work efficiency.
本発明は、以上のような不都合を解消した懸垂
