【Example】

 Hereinafter, an embodiment of the present invention will be described based on the present invention.

FIG. 1 is a schematic view showing an embodiment according to the present invention. A handle 108 made of resin is fixed by a screw provided on the center rod 101. The movable bone receiving and engaging portion 109 also made of resin slides up and down around the center rod 101, and the bone receiving and engaging portion 103 is fixed by screws provided on the center rod 101, and the sheet 110 is attached. After it is further tightened by the feet 113, it does not loosen or come off due to the double nut effect. The rib 106 made of resin is integrated with the receiving bone 104 by a hinge structure. The rib extension 105 is made of a pipe or a thin rod-shaped metal having a C-shaped cross section, and is inserted and held in a fitting hole groove formed in the rib 106. The connection between the ribs 106 and the receiving bones 104 and the respective bone receiving engaging portions 103 and 109 is performed by engaging the anchor type engaging portion provided at the tip of the receiving ribs 104 with the anchor type engaging portions provided on the bone receiving engaging portions. It is held by fitting into the groove. The sheet made of EVA, metallocene, or the like is welded to the rib extension 105 with holes 114-a that are welded to the rib extensions 105 provided at the corners of the sides. It is attached. The rib 106 is engaged with the tubular band 110-a provided at the welded portion of the sheet 110 to eliminate the displacement between the sheet and the rib, and the mating hole 114-a between the rib extension 105 and the groove 114 is oval. The shape and shape of the umbrella prevent irregular rotation of the tip, eliminate the misalignment between the seat and the bone, and improve the appearance as an umbrella.

The materials of the above components need to be unified in consideration of pollution problems and recycling efficiency in addition to workability and durability, and the following materials are preferable. The handle 108, the bone receiving and engaging portion 103, the movable bone receiving and engaging portion 109, the rib 113, the rib 106 and the receiving bone 104 are made of PP (polypropylene) which is elastic and hard to wear, or a polyolefin resin as a base material. Reinforcing materials such as aggregate may be blended according to the characteristics required for each part. The inner rod 101 and the rib extension 105 are preferably made of the same kind of metal, and are preferably made of an aluminum alloy in view of weight reduction and regeneration efficiency.

FIG. 3 and FIG. 04 are embodiments of each component. In FIG. 3, the center rod 101 has a screw portion 101-a for fitting with the handle 108, a stopper 101-b for holding the movable bone receiving engaging portion 109, and a stopper 101 for preventing excessive movement of the movable bone receiving engaging portion 109. A screw portion 101-d for fitting and fixing the -c to the bone engaging portion 104 and the stone protrusion 113 is provided. Further, the handle 108 is provided with a screw portion for fitting into the inner rod 101-a inside thereof, and is fixed to the inner rod 101 by a detachable structure. The movable bone receiving / engaging portion 109 is inserted into the center rod 101, and slides between the handle 108 and the stopper 101-c for preventing excessive movement. The bone engaging portion 104 is also provided with a screw portion for fitting with the center rod 101-d inside, and similarly, the inside of the stone protrusion 113 is also provided with a screw portion for fitting with the center bar 101-d. By tightening the joint portion 103 and the lip 113, they are fixed without being loosened by the double nut effect.

In FIG. 4, the ribs 106 and the receiving bones 104 are integrated by a hinge structure 104-a, and each end has an anchor-type engaging portion 106-b / 104− for fitting with the bone receiving engaging portion. b is provided, and can be inserted into a groove provided in the bone receiving engaging portion, rotated, and fixed. Removal is possible by the reverse procedure. The rib 106 is provided with a hole 106-a that fits with the rib extension 105, and the length of the bone can be set by inserting the rib extension 105. According to this structure, when setting the dimensions of the umbrella, it is possible to cope with it by changing the length of the rib extension, and commonality of parts can be achieved. For the rib extension 105, not only a pipe but also a profile extrusion in consideration of strength such as 105-a / 105-b is suitable. Further, the seat cover 110 is provided with a recess 114 at a corner of each side, and the recess 114 is provided with an engagement hole 114-a for engaging with the rib extension 105 so as to engage and fix with the rib extension 105. You.
