Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide support device for movably guiding and supporting a movable body such as a door plate, a closing plate (gate plate) and the like, and an opening / closing device using the guide support device.

[0002]

When it is desired to temporarily block the passage of a person at a ticket gate or a passage at a station, a closing plate which can be freely accessed is used. This closing plate is usually used when the passage is not closed. Is retracted and housed in the housing, and is taken out of the housing when the passage is closed.

By the way, in order to smoothly move the closing plate into and out of the housing, rollers are simply attached to the upper edge and the lower edge of the closing plate or the housing, and the upper edge and the lower edge of the housing or the closing plate. Even if the guide groove is formed, if the width of the roller and the guide groove do not match,
The closing plate may rattle in the direction perpendicular to the plate surface to generate unpleasant noise, or the roller may bite into the guide groove, so that even if the roller is attached, it may not be possible to secure smooth access. Further, when a roller is attached to the floor to smoothly move the closing plate in and out, there is a possibility that dust or sand may cause the roller to malfunction.

On the other hand, when a sliding guide rail is mounted in a housing without using a roller, a closing plate is slidably mounted on the sliding guide rail, and the closing plate is moved in and out by sliding. Since the support of the closing plate is cantilevered by the sliding guide rail in the housing, especially when the closing plate is located outside the housing, a large moment load is applied to the sliding guide rail, thereby closing the plate. There is a possibility that smooth entry and exit of the plate cannot be ensured.

[0005] The present invention has been made in view of the above-mentioned points, and an object of the present invention is to prevent a movable body such as a door plate or a closing plate (gate plate) from causing backlash or biting. SUMMARY OF THE INVENTION It is an object of the present invention to provide a guide support device that can smoothly guide and support the same and does not generate abnormal noise, and an opening / closing device that cantileverly supports a closing plate using the guide support device.
