Title: Curved fastening non-overturning ladder
Inventor: TAKAHASHI KOKICHI
IPC: E06C7/48
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent overturning by arranging a curved shaft above the uppermost stage footstep, and automatically moving the ladder center to the object side when leaned against a round object such as an electric pole. SOLUTION: A curved shaft 3 is rotatably installed in an upper position of the uppermost stage footstep 5 of follower metal 2 without fixing the left/ right both ends. Next, when a ladder is leaned against a round object 4 such as a garden tree and an electric pole, the ladder slidingly moves so that the lateral width directional center is always positioned in the center of the round object 4. When it becomes one leg since one of two legs of the ladder floats, the ladder does not slip out of the round object 4 since the curved shaft 3 always embraces the round object 4 inside. Therefore, safety and the working efficiency can be largely improved.

Abstract: PURPOSE:To secure a distance between cars by calculating the safe distance between cars while considering not only the speed of the own car but also the speed of a preceding car, and changing the interval of raising an alarm corresponding to the distance between cars. CONSTITUTION:A display unit 21 is equipped with a display part for the distance between cars, buzzer to raise the alarm and lamp to be turned on/off together with the generation of the alarm. In this case, a distance D between the own car 12 and a preceding car 22 is calculated by a laser rader unit 1. Velocity Vf of the own car is calculated by a car speed sensor 17. Velocity Va of the preceding car 22 is calculated by arithmetic corresponding to the change of the distance D between cars per a little time. Namely, the velocity Va of the preceding car is calculated according to relative velocity between the own car 12 and the preceding car 22. Therefore, the condition of alarm generation is when the sum of the braking distance of the preceding car and the distance D between cars is smaller than the sum of an automatic braking distance and the idle traveling distance of the own car.
