Looking at the internal configuration of the coupling portion 410 of the parasol according to the second embodiment of the present invention. The rotating body 460 has both side surfaces, and a part of the outer peripheral portion of one side of both sides has a tooth portion 470 each having a plurality of teeth, and there is a space for accommodating the release plate 450 inside both sides. Each tooth formed in the tooth portion 470 is engaged by the fastener 440, so that the rotor 460 is fixed at an angle set by the tooth. In addition, the groove formed by the tooth is formed of a vertical portion and an oblique portion, when the tooth is engaged with the fastener 440, referring to Figure 4b, the rotating body 460 is rotated counterclockwise and the clock It does not rotate in the direction. The other side of the rotating body 460 is connected to either one of the extended or upper slaughter. The fastener 440 is forced by the elastic means 430 so that the portion protruding from the fastener 440 may rotate downward. The elastic means 430 serves to give a rotational force by using the elastic force to the clamp 440, for example, a torsion spring.

The release plate 450 is mounted to the rotating body 460 so as to be rotatable, and the rotation is restricted by the upper protrusion 455 and the lower protrusion 457 formed at both ends, and the fixing plate is adjacent to the upper protrusion 455. A fixing groove 453 in which the 440 is engaged is formed. In addition, there is a semi-circular unlocking portion 451 having a radius longer than the length of the teeth formed in the rotating body 460 adjacent to the fixing groove 453 so that the clamp 440 unlocks the release plate 450. When lifted by 451, the tooth 470 is no longer fixed by the clamp 440, and the rotor 460 is free to rotate clockwise or counterclockwise. The lower protrusion 457 described above is formed in the unlocking portion 451.

The cover 420 is fixed. The second bolt 490 penetrates the center hole formed in the fastener 440 and the hole formed at one side of the elastic means 430 and the coupling part cover 420 to cover the coupling part 440 and the elastic means 430. Fix to 420.

Next, look at the operating principle of the coupling portion 410 of the parasol according to the second embodiment of the present invention. Referring to FIG. 4B, when the first extension line 150 is in line with the upper portion 130, the fixing rod 440 is inserted into the fixing groove 453 of the release plate 450. In 460, the upper portion of the tooth 470 is pressed. In this case the sunscreen extends in a straight line. Next, when the rotating body 460 rotates in the counterclockwise direction, the fastener 440 is engaged with the teeth 470 in a state of being fitted in the fixing groove 453 of the release plate 450 and rotates in the clockwise direction. This doesn't work. In this case, the sunshade is also inclined inwardly as the extended slaughter 150 is inclined with respect to the upper slaughter 130. Next, when the rotating body 460 rotates more than 90 degrees in the counterclockwise direction, and the portion where the rotating body 460 extends with the extension slab 150 pushes up the lower protrusion 457 of the release plate 450, the release is performed. The unlocking portion 451 of the plate 450 lifts the detent 440 so that the tooth 470 is no longer engaged by the detent 440. Therefore, the rotating body 460 can be freely rotated in a clockwise or counterclockwise direction, and if it continues to rotate in the clockwise direction, the protruding portion of the upper part of the rotating body 460 may move the upper protrusion 455 of the release plate 450. Push to rotate the release plate 450 clockwise to allow the upper groove 453 to be engaged with the clamp 440 again. Therefore, in this case, it is restored to the initial state, so that the elongated carcass 150 is in line with the upper carcass 130.
