Latest Patents

Furuzawa's latest patents include a damper for elevators and a method and apparatus for inspecting resin shock absorbers. The damper for elevators is designed to reduce the maximum deceleration of a lifting or lowering body by suppressing deformation of a foamed body that absorbs impact. This invention features urethane foam with a collision surface that interacts with the lifting or lowering body, along with an outer peripheral member that buffers impact through deformation.

The inspection method for resin shock absorbers allows for easy determination of the necessity for replacement at elevator inspection locations without requiring a car of rated weight. This method involves pressing an indenter into the resin shock absorber and measuring the repulsive force that causes the indenter to bounce back. The necessity for replacement is determined by comparing the measured value with a pre-established reference value.
