Description

  The present invention relates to an umbrella skeleton structure that supports the outer periphery of the umbrella densely and maintains its beauty.

  In a known multi-stage folding umbrella frame, each pair of radial umbrella elements each has at least one main bone (one main bone for tri-fold, two main for four-fold umbrella), middle bone and The caudal bone is connected in order from the inside to the outside, and since the umbrella surface is generally circular, the frame that is radially outward from the center is less distributed as it is closer to the center rod, and the central part of the umbrella surface is excessively supported, The outer periphery of the umbrella surface becomes insufficiently supported, the outer umbrella surface collapses downward, and the aesthetic appearance of the umbrella surface is impaired.

The object of the present invention is to provide a structure for improving the frame structure of a multi-stage folding umbrella, by improving the defect that the outer circumference of the umbrella surface collapses due to insufficient support of the outer circumference of the frame surface of a known multi-stage folding umbrella. The element forms a Y-shaped structure on the outer stage by branch design, and on each outer stage of the frame, the umbrella bones are concentrated in multiples of two, and sufficient support is formed on the outer periphery of the umbrella surface to enhance the beauty of the umbrella. It is to maintain.

  The frame improvement structure of the multi-stage folding umbrella of the present invention is that the main bone of one node, the middle bone of one node, and the tail bone of one node are pivoted in order from the inside to the outside, and the outer end is made the middle stage of the main bone by the short bone. The umbrella element is constructed by pivoting and connecting both ends to the outer end of the main bone and the inner end of the coccyx by a drawn line.

  According to the present invention, the multistage folding umbrella can maintain sufficient aesthetics of the umbrella by forming sufficient support on the outer periphery of the umbrella surface.

  FIG. 1 and FIG. 2 are three-dimensional views of the development and convergence state of the present invention. In order from the inside to the outside, a main bone 10 of a node, a middle bone 30 of a node, and a tail bone 40 of a node are pivotally connected. The short bone 20 pivots the outer end to the middle stage of the main bone 10, and both ends thereof are connected to the outer end of the main bone 10 and the inner end of the tail bone 40 by a drawing line 70 to constitute an umbrella bone element.

  The middle bone 30 includes a first branch middle bone 31 and a second branch middle bone 32.

  The tailbone 40 includes a first branch tailbone 41 and a second branch tailbone 42.

  The drawn line 70 includes a first drawn line 71 and a second drawn line 72.

  In the combination of the above-described elements, the outer ends of the first branch middle bone 31 and the second branch middle bone 32 pivot with the first branch tail bone 41 and the second branch tail bone 42 inner end of the tail bone 40, respectively. The inner ends of the first branch middle bone 31 and the second branch middle bone 32 are connected to a connecting portion 60 that is connected to the outer end of the main bone 10, and both ends of the first drawn line 71 are respectively connected to the main bone 10. The outer end is connected to the inner end of the first branch tailbone 41, and both ends of the second drawn line 72 are connected to the outer end of the main bone 10 and the inner end of the second branch tailbone 42, respectively. The outer side of the main bone 10 is defined by a first branched middle bone 31, a second branched middle bone 32, a first branched tailbone 41, a second branched tailbone 42, and a first drawn line 71 and a second drawn line 72. This constitutes a U-shaped umbrella element. The inner ends of the main bone 10 and the short bone 20 are pivotally connected to an annular cistern in the periphery of the upper nest 51 and the lower nest 52 of the umbrella center rod 50, respectively. Configure. At the time of deployment of the skeleton, the first branch middle bone 31, the second branch middle bone 32, and the first branch bone pivoted by a multiple of two to the outer stage of each main bone 10 by each umbrella bone element having a Y-shaped structure The branch tailbone 41 and the second branch tailbone 42 form a uniform support function with respect to the umbrella surface.

  As shown in FIG. 3, the inner ends of the first branch middle bone 31 and the second branch middle bone 32 are made of a rigid material, and the connecting portion 60 where the outer end of the main bone 10 is pivoted has a large outer end. The outer end of the large opening is a flat sleeve body with an opening, and the inner ends of the first molecular middle bone 31 and the second branch middle bone 32 are inserted, and the shaft sheath 61 is drilled into the flat sleeve body and pivoted. The first branch middle bone 31 and the second branch middle bone 32 are flexibly opened at a certain angle by a large opening at the outer end of the connecting portion 60, and the structure cost is slightly high, but flexible deployment and accommodation are possible.

  As shown in FIG. 4, the first branch middle bone 31 and the second branch middle bone 32 employ a tough material, for example, a fiber or plastic material, and the inner end is integrally molded or other In this manner, the connection portion 60 is consolidated to the outer end. The inner end of the connecting portion 60 and the outer end of the main bone 10 (FIG. 3) are pivotally connected and open at a certain angle due to the toughness of the material of both branched middle bones 31 and 32 themselves. However, such a structure is relatively cheap.

  FIG. 5 is a cross-sectional view of a first type coupling example of the first drawing line, the second drawing line and the main bone outer end according to the present invention. The first drawn line 71 and the second drawn line 72 are difficult in terms of assembly work because one drawn line is curved at the middle stage and an intermediate curved stage 73 is drilled at the outer end of the main bone 10. The constructed structure is sturdy and difficult to fall off.
