AI Technical Summary
Technical Problem
Conventional opening/closing devices for outdoor-indoor spaces lack guide members that enhance fire protection (flame shielding) performance while also considering design aspects.
Method used
The development of a guide member for opening/closing devices that incorporates a holder member made of steel, covering the sides of the guide member except for the sides facing the panel body, and optionally using an aluminum alloy for the guide member itself, along with a detection sensor integrated within a guide member cover.
Benefits of technology
This configuration improves the fire protection performance of the guide member while maintaining a design-focused approach, ensuring both safety and aesthetic considerations are met.

Abstract
To provide a guide member capable of improving fire prevention (flame shielding) performance of a guide member while considering the design.SOLUTION: An opening / closing mechanism 1 opens / closes an opening formed in a wall that separates the indoor and the outdoor. The opening / closing mechanism 1 includes: multiple panel members 11B arranged in the vertical direction to partially overlap each other; guide members 12 for guiding movement of in the vertical direction of each panel member 11B; guided members Wh attached to both ends of the panel member 11B in the longitudinal direction to move along the guide members 12; and holder members 131 formed of a steel material fully covering the sides along the longitudinal direction other than the side facing panel members 11B of the guide members 12.SELECTED DRAWING: Figure 23
