Problems solved by technology

[0007] The connecting structure of the root of such an umbrella shaft (hub) and umbrella ribs (ribs) is the same for the upper umbrella shaft (crownhub) and the middle umbrella shaft (upper sliding hub). When disposing of damaged umbrellas, it is also difficult to separate metal parts and non-metal parts for separate disposal. Therefore, it is difficult to realize the recycling of valuable resources.

Abstract

The present invention can easily separate and discard metallic parts and nonmetallic parts from each other in the case of disassembling an automatically-opened umbrella to discard. A flange-like stretcher pivotally supporting part having a plurarity of stretcher housing grooves formed radially at its periphery is provided at a lower runner made of resin. Metallic pivotally supporting rings facing all of the plurarity of stretcher housing grooves of the stretcher pivotally supporting part are fitted coaxially and detachably from the lower surface side of the stretcher pivotally supporting part to pivotally support the U-shaped root parts of metallic rib in the rib housing grooves in a removable state.

Description

technical field [0001] The present invention relates to umbrellas, and more particularly to an umbrella that is not only easy to assemble during manufacture, but also can easily sort and discard non-metallic materials such as metal members and synthetic resins when discarding damaged umbrellas. Automatically open the umbrella (button operated umbrella) of the nonmetal member. Background technique [0002] In recent years, button operated umbrellas are being sold in large quantities due to their convenience in use. The structure of a typical automatic open umbrella has the same structure as the manual open umbrella: it is used to pivot the root of the main ribs (pivoting), and is fixed on the upper umbrella shaft (crown hub) at the front end of the pillar (shaft). ); and a lower sliding hub (lower sliding hub) which is slidably embedded on the pillar and opens and closes the umbrella based on its sliding action, between the upper umbrella shaft and the lower umbrella shaft i...
