| 摘要 | PURPOSE: To make an umbrella to be stably and easily handled, by equipping a tilting means between the top part of the shaft and a location member. CONSTITUTION: A shaft placed between a runner 2 and a notch 3 is equipped with a joint 1. When proper force is applied on the joint 1 to bend the shafts 4, 5, a protrusion 12 is easily drawn out from a dent part 14 to retain the joint 1 in a prescribed angle by the elasticity of the material of a cup 11. When the joint 1 is bent into the maximum angle, the protrusion 12 goes into a ring- like protrusion 15 which makes the bent shaft not to be shaken. Further, the neck 13 presses the edge part of the cup to make the joint extremely stable. COPYRIGHT: (C)1990,JPO |
