AI Technical Summary

Technical Problem

Conventional runner units require complex and unstable installation processes for door panels, especially when dealing with heavy sliding doors, making it difficult for a single worker to securely hang the door panels due to the need to support the door with one hand while manipulating the connecting mechanism.

Method used

A runner unit with a connecting shaft and runner that allows for easy attachment by aligning the door panel with an insertion recess, using a retainer that switches between restricted and released positions to securely hold the connecting shaft, and a guide surface to facilitate smooth attachment without needing to manually stabilize the door panel.

Benefits of technology

Enables quick and stable hanging of door panels with reduced effort, ensuring safety and simplicity in installation, even with heavy doors, and allows for easy detachment without additional complex structures.

Abstract

To provide a runner unit capable of simply and quickly hanging a door panel by connecting a connection shaft and a runner only by operation on the door panel side in hanging work of the door panel, and an interlocking opening / closing unit provided with the runner unit.SOLUTION: A runner unit 6 includes a runner 8 having an insertion recessed part 24 and a receiving part 25 and guided along a guide rail 2, and a connection shaft 7 having an enlarged shaft part 12 received by the receiving part 25 and formed on a door panel 1 to project therefrom. Inserting the connection shaft 7 into the insertion recessed part 24 causes a holding body 20 to change into a release attitude, the enlarged shaft part 12 is displaced from the insertion recessed part 24 to the receiving part 25, the displaced enlarged shaft part 12 is received by the receiving part 25, the holding body 20 is changed into a regulation attitude, the connection shaft 7 is held in position by the holding body 20 in the regulation attitude in a state where the enlarged shaft part 12 is received by the receiving part 25, and the connection shaft 7 and the runner 8 are connected.SELECTED DRAWING: Figure 1
