Description

[Detailed description of the invention] This invention relates to a folding umbrella, particularly a trifold type folding umbrella.

Although bifold umbrellas have existed for a long time, trifold umbrellas, which are more convenient to carry, have recently been developed and are now on the market.

However, as shown in Fig. 3, this three-fold umbrella connects the lower wheel 1 and the middle rib 4 with one base rib 2, and connects the upper wheel 9 and the middle part of the base rib 2 with the base rib 10. Furthermore, the base rib 10 and the middle rib 4 are connected by a spring wire 11.

Therefore, the fabric 12 around the center area is concavely stretched downward as shown in the figure, resulting in a very poor appearance, and also has the disadvantage that rainwater collects in this concave area.

The main purpose of this invention is to eliminate the above-mentioned conventional drawbacks and provide a three-fold folding umbrella that does not spoil its appearance and does not impede drainage of rain.

However, in this device, the base bridge 2 attached to the descending cross 1 and the leading rib 5 connected to the middle rib 4, which is foldably connected to the leading rib 3, are connected in a bendable and extensible manner by a pin 6, and then the ascending cross 9
and the first bridge 5 on the side of the middle rib 4 are connected by a base rib 10, and the middle rib 4 connecting the base rib 10 and the first bridge 5 are connected to each other by a spring wire 11. The gist of this paper is the structure of a three-fold folding umbrella.

In the illustrated embodiment, the spring wire 7 attached to the first frame 5 is engaged with a pin 8 extending across the base frame 2, so that the bending/extension angle is limited to a constant value.

In the figure, 13 is the dew point provided at the tip of the proximal rib 3, 14 is the middle rod,
Reference numeral 15 indicates an upper flip, 16 indicates a stabilizing metal fitting attached to the connecting portion between the leading rib 15 and the middle rib 4, 17 indicates a connecting fitting between the leading rib 15 and the middle rib 4, and 18 indicates a pivot pin.

Since this device has a construction in which the umbrella is unfolded as shown in Fig. 2, it is divided into two parts and connected to each other with pins 6 so as to be bendable and extensible. The connecting part of the strut 5 comes into pressure contact with the base rib 10 on the upper wheel 9 side, lifts the spring wire 11 and the base rib 10, and stretches them in a straight state, so they do not bend downward as in the conventional case. Never.

Therefore, it is possible to eliminate the defect of depression around the center when the umbrella is unfolded, and the value of the umbrella as a trifold folding umbrella is increased.

Claims (1)

[Scope of utility model registration request] The base bridge 2 attached to the lower wheel 1 and the front bridge 5 connected to the middle rib 4, which is foldably connected to the front rib 3, are connected in a bendable and extensible manner with pins 6, and then connected to the upper wheel 9 and the middle rib. The three-fold structure is characterized in that the base ribs 10 are connected to the first frame on the four sides, and the base rib 10 and the middle rib 4 connecting the first frame 5 are connected to each other by a spring wire 11. A folding umbrella.
