Problems solved by technology

However, the raised portion 92 is roughly H-shaped, and additional processes and tools are required to form the through hole 93 in the middle during injection molding, which is not convenient enough to make.
In addition, the outer end of the metal stay wire is usually hooked at the through hole of the joint provided at the inner end of the coccyx, and the hooked part of the stay wire is exposed. cloth

Embodiment Construction

[0024] The ribs of the multi-fold umbrella of the present invention can be applied to multi-fold umbrellas that are opened automatically or by hand. The following uses a three-fold umbrella as an example to describe in detail with reference to the accompanying drawings.

[0025] Such as figure 2 As shown, the ribs of the multi-fold umbrella of the present invention include: the first rib 1, the second rib 2 and the third rib 3 connected sequentially from the inside to the outside, and the outer end is connected to the middle of the first rib 1 The fourth umbrella rib 7, backguy 4 and backguy 8. The inner end of the third rib is fixedly provided with a first joint 31, the inner and outer ends of the second rib 2 are respectively fixed with a fourth joint 25 and a second joint 21, and the outer end of the first rib 1 is fixed with a The third joint 11 and the fifth joint 71 are fixed on the outer end of the fourth rib 7, and the above joints are usually made of plastic materia...

Abstract

The invention relates to a multi-folding umbrella rib. The multi-folding umbrella rib comprises a first rib (1), a second rib (2), a third rib (3) and a pull wire (4) which are connected sequentially from the inside to the outside; the second rib (2) is provided with a lug boss (5) with a through hole (51) through which the pull wire (4) passes; the lug boss (5) comprises a basal part (52), a first extension part (53), a second extension part (54) and a connecting part (55), the first extension part (53) and the second extension part (54) upwardly extend from the basal part (52), and the connecting part (55) is connected with the first extension part (53) and the second extension part (54); the first extension part (53) and the second extension part (54) are staggered longitudinally and respectively arranged at the left side and right side of the basal part (52). The injection molding of the multi-folding umbrella rib disclosed by the invention is highly convenient and efficient, man hours are saved, moreover, the phenomenon that a fabric is injured by the end of the pull wire cannot take place, and in the process of using the rib, the rib joint cannot easily shift as well.

Description

technical field [0001] The invention relates to a part of an umbrella used in daily life, in particular to an improved rib structure of a multi-fold umbrella, which is suitable for automatic or hand-opened multi-fold umbrellas. Background technique [0002] Existing multi-fold umbrellas, such as the common three-fold umbrella made of glass fiber material, are connected by metal stay wires between the outer end of the main bone and the inner end of the coccyx. Bend the middle part of the pull wire into a U-shape and place it on the bottom of the sub-bone between the main bone and coccyx, but in this way, during the process of opening and closing the umbrella, the U-shaped part of the pull wire will scratch the fiberglass sub-bone, making the sub-bone The bone fades, stabs the hand, and it is easy to elongate and deform the U-shaped structure of the backguy, resulting in unsmooth opening and closing of the umbrella. For this, as figure 1 As shown, someone is provided with a ...
