Third Embodiment

As another example of the fastening member described above, the angle of the light blocking portion relative to the vertical support may be adjusted while the vertical support and the light blocking portion are fastened.

In the drawings, Figure 14 is a front view showing the connecting portion and the vertical support portion of the coupling member for coupling the upper rib and the lower rib of the parasol, Figure 15 is a perspective view showing a first coupling portion to which the upper rib is coupled, Figure 16 is a lower rib Is a perspective view showing a second coupling part to be coupled. 17 is a cross-sectional view showing a coupling portion of the coupling member and the vertical support, Figure 18 is a perspective view showing the inner surface of the holder, Figure 19 is a perspective view showing the inner surface of another holder facing. 20 is a cross-sectional view showing the operation of the coupling member according to the angle of the light shielding portion, Figure 21 is a front view of the connection portion showing the process when the light shield is expanded or folded.

In the description of the parasol according to the third embodiment, since the description and the drawings of the elastic rib 123 and the light shielding cloth 110 have been described in detail in the first and second embodiments, detailed description thereof will be omitted. .

As shown in FIG. 2 and FIG. 14, the vertical support 105 for supporting the light shielding portion 103 has a holder 170 inserted at an upper end thereof and fixed to an end of the upper rib 121 at the holder 170. The first coupling part 161 is mounted and the second coupling part 162 fixed to the end of the lower rib 122 is inserted into the holder 170 in a state in which the first coupling part 161 is aligned with the first coupling part 161. The coupling part 162 is separated from the first coupling part 161 after exiting from the holder 170.

Here, in the state where the light shielding unit 103 is unfolded or folded, the second coupling unit 162 is inserted into the holder 170 while being mounted with the first coupling unit 161, and the light blocking unit 103 is unfolded or folded. During the losing process, the second coupling part 162 is separated from the first coupling part 161 in a state where the second coupling part 162 comes out of the holder 170.

This configuration will be described in detail.

The holder 170 inserted into the upper end of the vertical support 105 is fixed upward with the two lugs 171 facing each other.

In addition, the first coupling part 161 illustrated in FIG. 15 is rotatably mounted in a state located between the two lugs 171 facing each other. The first coupling portion 161 has a slot 161S formed at one side thereof, and the upper rib 121 is inserted into the slot 161S, and a recess 161H is formed at the bottom of the first coupling portion 161. The recessed portion 161H is formed in the same direction as the longitudinal direction of the slot 161S. In addition, a through hole 161R is formed in the middle of the first coupling part 161 in the same direction as the slot 161S and the concave part 161H, and the second rotating shaft 175 penetrating the two lugs 171 passes through the through hole 161R. It penetrates the ball 161R. Accordingly, the first coupling part 161 is rotatable about the second rotation shaft 175, and as the first coupling part 161 rotates, the upper rod 121, that is, the light shield 103, is rotated about the second rotation shaft 175. It will pivot up and down with the center.

When the first coupling portion 161 pivots upward with respect to the second rotation shaft 175, the recess 161H formed in the first coupling portion 161 is positioned outside the lug 171. That is, when the light blocking portion 103 is raised upward, the recessed portion 161H is positioned outside the lug 171. When the light blocking portion 103 is positioned substantially perpendicular to the vertical support 105, the recess 161H is positioned inside the lug 171, that is, in the holder 170.

Meanwhile, as shown in FIGS. 16 to 21, the second coupling part 162 is positioned under the first coupling part 161. The second coupling part 162 has a slot 162S formed at one side thereof, and the lower rib 122 is fitted into the slot 162S to be fixed. The convex portion 162P is formed on the upper surface of the second coupling portion 162 to match the concave portion 161H. In addition, the groove 163 is formed along an arc around the second rotating shaft 175 on one side facing the lug 171. Protrusions 173 corresponding to the grooves 163 are formed on the inner surface of the lug 171. When the groove 163 and the protrusion 173 are matched, the second coupling part 162 does not rotate about the second rotation shaft 175.

Coupling force of the groove 163 and the protrusion 173 is such that the light shielding portion 103 does not turn around by the external force around the second rotary shaft 175, the user to the holder 170 from the support 105 Forcibly turning up and down while fixing the light shield 103, and the holder 170 is disengaged by disengaging the coupling between the groove 163 and the protrusion 173 by the elasticity of the lug 171 fixed to the second rotation shaft. Will rotate. Therefore, when the user adjusts the vertical angle of the light shielding part 103 and then inserts the holder 170 on the top of the support 105, the light shielding part 103 does not turn by the coupling force of the groove 163 and the protrusion 173. It will be fixed at the adjusted angle.

In order to unfold the light shield 103 in such a structure, as shown in FIG. 21, the user pushes up the folded light shield 103. Then, the light blocking part 103 pivots upward with respect to the second rotation shaft 175 of the holder 170 while the concave part 161H and the second coupling part 162 of the first coupling part 161 are held by the holder 170. Come out. At this time, the groove 163 of the second coupling portion 162 and the protrusion 173 of the lug 171 are dismantled. As such, when the second coupling part 162 comes out of the holder 170, the light blocking part 103 may pivot about the first rotational axis 141 and thus be unfolded. That is, when the lower rib 122 rotates about the first rotation shaft 141 and the light shield 103 is unfolded, the second coupling part 162 is again positioned under the first coupling part 161 and the first coupling is performed. The concave portion 161H of the portion 161 and the convex portion 162P of the second coupling portion 162 are matched.
