Title: Outdoor hollow post and its installation
Inventor: NOMURA MASAHARU
IPC: E04H17/22
Filed: 1992-12-08
Abstract: PURPOSE:To keep the beautiful sense of an external structure installed outdoors. CONSTITUTION:After a metallic hollow post body 1 is fixed at a specified position, a non-metallic setting fluid material is poured from the upper opening 11 as a charging material 2 to fill the hollow space. After the material is hardened, the opening is fitted to another member to assemble the hollow post having an independent beautiful appearance. A hardening and foaming polyurethane is particularly preferable as a filter. Since the filler is charged in the hollow inside without any spaces, even if rainwater or melt-water forcibly enters into the inside from the fitting part to the other member, it is impossible to permeate. And hence, it is not feared that the good appearance is spoiled because of red rust or corrosion.

IPC: B66B5/00
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To provide an elevator controller capable of providing good operability to a user by a simplified system and properly securing the security of a building. SOLUTION: When a visitor from the outside of a building and the resident of the building communicated with each other via communication devices 1a to 1n, each of the communication devices 1a to 1n outputs the residing floor signal of the resident.
