  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.

  As shown in FIGS. 1 to 3, the folding umbrella according to the present invention includes a middle rod 10 that is an elongated rod body, an upper rocker 20 provided near the upper end of the middle rod 10, and a lower portion of the upper rocker 20. The lower rocker 30 slidably provided along the middle rod 10 so as to be positioned, a plurality of main bones 40 pivoted on the upper rocker 20 at an equal angle with each other, and the lower rocker 30 at an equal angle with each other A plurality of receiving bones 50 are provided, and an umbrella fabric 60 is provided on the upper part of the parent bone 40 so as to cover the plurality of parent bones 40. The main bone 40 includes a rear stage 41 pivoted on the upper rocker 20, a middle stage 42 extended to the rear stage 41, a link member that joins the rear stage 41 and the middle stage 42 and has a tab 431 projecting downward. 43 and a front stage 45 having one end pivoted to the middle stage 42.

  Further, the folding umbrella according to the present invention includes a pivotal bone 44 that pivots with each of the parent bone 40 and the receiving bone 50. The link member structure of the folding umbrella according to the present invention mainly includes a parent bone 40, a receiving bone 50, and a pivotal bone 44. The pivotal bone 44 has an elongated shape and is formed by bending a metal thin plate, and a first clip portion 441 is formed at one end and a second clip portion 442 is formed at the other end. .

  The first clip portion 441 is provided so as to be located on both sides of the tab 431 of the link member 43, and the link member 43 and the pivotal bone 44 are pin 46 via the first clip portion 441 and the tab 43. It is pivoted by. The second clip portion 442 is provided so as to sandwich the outer end of the receiving bone 50, and is pivotally provided by the pin 46 via the receiving bone 50, the pivotal bone 44, and the second clip portion 442. As described above, the link member 43 and the receiving bone 50 of the parent bone 40 are pivoted at both ends of the pivotal bone 44 via the first clip 441 and the second clip 442, respectively. The outer end of the receiving bone 50 is preferably pivoted from the outer end of the second clip portion 442 of the pivoting bone 44 to a location that is approximately 1/4 of the length of the pivoting bone 44.
