A locking device for a guide rail is disclosed. The device includes a first edge including a plurality of teeth shaped projections. The first edge compresses and locks a first surface of a covering sheet placed on a base ring. The device also includes a second edge opposing the first edge. The second edge includes a V-shaped groove, wherein the second edge is disposed to hold at least one furrow of the guide rail for interlocking. The first edge and the second edge of the locking device locks air gap between the covering sheet, the guide rail connecting one or more surfaces of the base ring and a vertical pillar coupled to the guide rail.

A system and method used to translate a building structure (e.g., a single-family home) from a first position (e.g., above grade) to a second position (e.g., below grade) is provided. The system may thereby protect building structures from above grade threats such as wildfires, tornados, hurricanes, and other threats by lowering the building structure into a below grade cavity and sealing it therein. The system may include a base that supports the building structure and a translation system that lowers the base and the building structure below grade. The translation system may include scissor lifts, hydraulic lifts, jackscrew lifts and/or other types of lifts. The system also may include a quick release utilities system to disconnect the various utilities during the translation and a protective roof that may be extended over the top of the building structure to protect it from the threats above.

An elevator cabin seal for an elevator is described. The elevator cabin seal includes a plate having a plate interior surface, a seal member, and a plurality of adjustment members. The seal member has a seal member interior surface and a seal member top surface contiguous with the seal member interior surface. The seal member top surface is coupled to the plate interior surface. Each adjustment member of the plurality of adjustment members is coupled to the plate interior surface and contacts the seal member interior surface to exert an adjustable force against the seal member interior surface.

An illustrative example embodiment of an elevator system includes a platform and a plurality of supports configured to selectively engage a nearby structure. The plurality of supports include at least a first support and a second support. The first and second supports alternate between engaging the nearby structure to support the platform while the other one of the supports is disengaged from the nearby structure. At least one of the first and second supports is configured to move relative to the platform while engaging the nearby structure to cause vertical movement of the platform.

An overload valve assembly for a pneumatic vacuum elevator is disclosed. The overload valve assembly for a pneumatic vacuum elevator is characterised by a fastening means, a pad with a centre hole, an arresting plate with a centre hole, a disc plate with a centre hole, a bottom bush, a spring and a top bush bounded with a nut. Here, the pad, the arresting plate, the disc plate, the bottom bush, the spring and the top bush bounded with the nut is fitted over the fastening means. The overload valve unit is configured to function based on spring actuation mechanism and ensure the maximum permissible limit of pay load in the elevator cabin assembly.
