Modern Umbrella

Abstract

This invention proposes a modern umbrella, which consists of ribs, nests, shaft and canopy. The ribs have long ribs and supporting ribs, and the nests are composed of upper nest and lower nest, with the lower nest composed of several disks from up to down. Between two neighboring disks is a connecting tube, and the disks mentioned above have several mounting notches, which are not arranged in order. One end of supporting rib is articulated to mounting notch, and the other end to long rib. With regard to two neighboring disks, the distance from the joint between supporting rib connected with upper disk and long rib to upper nest is no greater than the distance from the joint between supporting rib connected with lower disk and long rib to upper nest. The canopy clings to long ribs to shape various concave-convex surfaces. Through layers of disks at the lower nest, the canopy clinging to ribs shows the staggered arrangement of concave-convex surfaces to improve water diversion effects, air flow dispersion ability and the ability to withstand wind. Meanwhile, such design can achieve the aim of folding the umbrella safely.

1 . The umbrella consists of ribs, nests, shaft and canopy. The ribs have long ribs and supporting ribs, and the nests are composed of upper nest and lower nest. The upper nest is fixed at the upper part of the shaft and the lower nest has slide cooperation with shaft. The lower nest has various disks from up to down, which are equipped with several mounting notches that are not arranged in order, and two neighboring disks are furnished with a connecting tube. One end of the supporting rib is articulated to the mounting notch and the other end to the long rib. The canopy is connected with long ribs to shape various concave-convex surfaces. 
     
     
         2 . As described by  claim 1 , the shaft of the modern umbrella has a sleeve which is connected with the lower part of upper nest. The outer wall of the sleeve is armed with a limiting stopper which limits the initial angle between long ribs and shaft when the long ribs are stretched. 
     
     
         3 . As described by  claim 1 , the disks of upper and lower nests are designed with wire grooves which have a wire. The section between ribs and nests is furnished with articulated holes. The wire will go through articulated holes and its two ends will be bound with each other. The wire groove is furnished with protection notch, inside which there is a joint between wire's two ends, and besides, there is a cap at the top of the protection notch. 
     
     
         4 . As described by  claim 1 , disk's side walls are equipped with several closing notches characterized by axial arrangement. In terms of location, the closing notches are parallel to mounting notches at all disks under the corresponding disks. 
     
     
         5 . As described by  claim 1 , for two neighboring disks, the length of supporting rib connected with upper disk and the distance from the joint between supporting rib connected with upper disk and long rib to upper nest are equal to the length of the supporting rib connected with lower disk, the distance from the joint between supporting rib connected with lower disk and long rib to upper nest, the length of connecting tube, etc. 
     
     
         6 . As described by  claim 5 , for two neighboring disks, the distance from the joint between supporting rib connected with upper disk and long rib to upper nest is no greater than the distance from the joint between supporting rib connected with lower disk and long rib to upper nest. 
     
     
         7 . As described by  claim 1 , the long ribs connected with supporting ribs of the same disk share the same length, which however will be different when they are linked with supporting ribs of different disks. 
     
     
         8 . As described by  claim 1 , the edge of the canopy's part located between two long ribs and far away from upper nest has an arc-shaped structure. 
     
     
         9 . As described by  claim 1 , there is a tip between the canopy and one side of the long rib far away from upper nest, and the tip consists of inner core and outer bead. One end of inner core is fixed at the long rib and the other end is connected with outer bead, which is fixed at one edge of the upper nest far away from the canopy. The outer bead is matched up with the inner core. 
     
     
         10 . As described by  claim 9 , there is a slot at one side of the outer bead facing inner core, and the slot has several holes at its side wall. The inner core is equipped with a block at the side facing outer bead, and its outer wall is furnished with a buckle. The block will be inserted into the slot and the buckle into the hole. 
     
     
         11 . As described by  claim 1 , the shaft is equipped with an extended rod connected to the lower nest at its lower part. The shaft is installed with a latch, and the length of the extended rod is equal to the distance from the latch to the lower side of the sleeve. 
     
     
         12 . As described by  claim 1 , there is a ferrule at the top of shaft, which is connected with the upper nest at its top, and there is a non-slip pad at the top of the ferrule. 
     
     
         13 . As described by  claim 12 , the shaft is equipped with an elastic plastic loop at its top, which is located between the ferrule and the upper nest and above the joint between the canopy and the shaft.
