Mode for Carrying Out the Invention

[0012] The mode for carrying out this invention will be described. It is a plan view showing a parasol, and FIG. 2 is the corresponding front view. [[ID=3�]]

[0013] The parasol 1 includes a center pole

[0014] In the umbrella cloth piece 3, a first rib 6 is provided along the first side 4, and a second rib 7 is provided along the second side 5. And a first receiving rib 8 for supporting this is provided at the middle part of the first rib, and a second receiving rib 9 for supporting this is provided at the middle part of the second rib.

[0015] Near the upper end of the middle rod 2, an upper pulley 10 is provided. FIG. 3 is a front view showing the upper pulley. The upper pulley 10 has a first upper pulley connection portion 11 that rotatably supports one end of the first rib 6 and a second upper pulley connection portion 12 that rotatably supports one end of the second rib 7. When there are 8 umbrella cloth pieces 3, since there are 8 first ribs 6 and 8 second ribs 7 respectively, 8 first upper pulley connection portions 11 and 8 second upper pulley connection portions 12 are also provided respectively.

[0016] The first upper pulley connection portion 11 and the second upper pulley connection portion 12 are provided at close positions, but the second upper pulley connection portion 12 is at a position slightly lower than the first upper pulley connection portion 11. Also, at positions along the outer periphery, the first upper pulley connection portion 11 and the second upper pulley connection portion 12 are provided at positions slightly shifted from each other, and when viewed from above, the second upper pulley connection portion 12 is at a position slightly advanced in the clockwise direction. By shifting the first upper pulley connection portion 11 and the second upper pulley connection portion 12 in this way, interference between the first rib 6 and the second rib 7 and interference between the first receiving rib 8 and the second receiving rib 9 can be prevented or reduced.

[0017] Below the upper pulley 10, a first lower pulley 13 that rotatably supports one end of the first receiving rib 8 and a second lower pulley 14 that rotatably supports one end of the second receiving rib 9 are provided. FIG. 4 is a front view showing the first lower pulley, FIG. 5 is a front view showing the second lower pulley, and FIG. 6 is a front view showing a state in which the first lower pulley and the second lower pulley are combined.

[0018] The second lower pulley 14 is a cylindrical hollow member, and the middle rod 2 passes through a hole inside. On the outer peripheral portion, a second receiving rib connection portion 16 that rotatably supports one end of the second receiving rib 8 is provided. On the upper part of the middle rod 2, an upper stopper 17 that can move in and out freely outside the middle rod 2 is provided as a stopper, and holes through which this upper stopper 17 enters and exits are provided at two upper and lower positions of the second lower pulley 14. The upper hole is the first stopper hole 18, and the lower hole is the second stopper hole. A flange portion 20 with a large diameter is formed at the lower end portion of the second lower pulley 14.

[0019] The first lower wheel 15 is also a cylindrical hollow member, with a hole inside through which the second lower wheel 14 passes. The outer circumference is provided with a first support bone connection part 15 that rotatably supports one end of the first support bone 7. In addition, there is a single release hole 21 through which the upper release bone 17 enters and exits. A protruding second lower wheel contact part 22 is formed at the lower end of the first lower wheel 13.

[0020] A lower spring 23 is provided on the handle side of the central rod. Furthermore, a grip portion 24 is provided on the handle side of the central rod 2. The grip portion 24 is a hollow member, and the central rod 2 passes through the hole inside. The central rod 2 is provided with a stopper that restricts the movement of the grip portion 24 in the longitudinal direction. On the other hand, the rotation of the grip portion 24 relative to the central rod 2 is not restricted and it is rotatably attached.

[0021] The function of the following parasol 1 will be explained. Figure 7 is a conceptual diagram illustrating the function of the parasol, showing one piece of umbrella fabric 3. Both are in the open state, but Figure 7(a) shows the parasol state and Figure 7(b) shows the fan state.

[0022] In Figure 7(a), the first lower wheel 13 has moved upward, and the upper flick 17 is in the flick hole 21. The second upper wheel 14 has also moved upward, and the lower second flick hole 19 is in a position to overlap with the flick hole 21 of the first lower wheel 13, with the upper flick 17 in place.

[0023] In this state, the heights of the first rib connection point 15 and the second rib connection point 16 (along the length of the central shaft 2) are closest. The outer ends of the first rib 8 and the second rib 9 are also at approximately the same height. Therefore, when viewed from the side, the outer edges of the umbrella fabric piece 3 appear almost horizontal.

[0024] The first rib 8 and the second rib 9 attached to all the umbrella fabric pieces 3 are synchronized, so that all the umbrella fabric pieces 3 are in the same state. At this time, the parasol 1 will be in the state shown in Figure 2, and the umbrella fabric pieces 3 will give it a polygonal pyramidal shape like a normal parasol. The gaps between the umbrella fabric pieces 3 will be minimized, effectively blocking sunlight and making it suitable for use as a parasol.

[0025] Next, let's explain the fan state. Move the second upper wheel 14 lower than in the parasol state, aligning the upper first flick hole 18 with the flick hole 21 of the first lower wheel 13, so that the upper flick 17 is inserted.

[0026] In this state, the second support rib connection part 16 is lower than the first support rib connection part 15. The outer peripheral end of the second rib 9 is lower than the outer peripheral end of the first rib 8. This causes twisting in the umbrella fabric piece 3, forming the shape of a propeller blade. Figure 8 is a front view showing the parasol in the fan state.

[0027] In the fan-like state, a large gap is created between the connected umbrella fabric pieces 3, allowing air to enter and exit. This improves ventilation and prevents heat from accumulating inside the polygonal pyramid formed by the umbrella fabric pieces 3.

[0028] By rotating the central pole 2, the umbrella fabric pieces 3 can be made to act as propellers, generating wind. Hold the handle at the base of the central pole 2 with your dominant hand and the grip section 24 with your other hand. By turning the handle, the central pole 2 rotates, causing the propeller-shaped umbrella fabric pieces 3 to rotate and generate wind. By rotating it in a direction that generates downward wind, the wind can be directed at the user's body to cool them down. It can easily generate wind even when there is no wind, and is also useful for preventing heatstroke.

[0029] Furthermore, the propeller-shaped design of the parasol gives it a novel feel. The way it transforms from a regular parasol into a propeller shape and generates wind like a fan is playful and satisfying.

[0030] Figure 9 is a front view showing an example of a handle. In this example, it is divided into a handle-side portion 25a provided at the handle-side end of the central rod 2, and an end-side portion 25b provided following the handle-side portion 25a.

[0031] Figure 10 is a left side view showing the handle portion. A projection 25c with a rectangular cross-section protrudes from the tip of the handle portion 25a. On the other hand, a recess 25d with approximately the same rectangular cross-section is provided at the tip of the end portion 25b. The projection 25c of the handle portion 25a can be inserted into the recess 25d of the end portion 25b. Alternatively, the projection 25c may be provided on the end portion 25b and the recess 25d on the handle portion 25a.

[0032] The handle side portion 25a and the end side portion 25b each have a circular arc shape (arc portion) that is approximately one-quarter of the circumference. Furthermore, a connecting portion is formed by a projection portion 25c and a recess portion 25d that detachably connects the handle side portion 25a and the recess portion 25d.

[0033] Figure 11 is a front view showing the handle in the parasol state. The handle side 25a and the end side 25b are connected so that both arcs are convex downwards, forming a semicircle. In this state, the connected handle has a hook shape similar to that of a normal umbrella, making it suitable for holding as a parasol or when the umbrella is closed.

[0034] Figure 12 is a front view showing the handle in the fan position. The end side portion 25b is connected in an inverted state. The arc portion of the end side portion 25b is convex upwards, and the handle side portion 25a and the end side portion 25b form an S-shaped crank. When the parasol is in the fan position, the central shaft 2 can be easily rotated by gripping the handle portion 24 with one hand and the end side portion 25b with the other hand.

[0035] Switching between the parasol and fan modes of the handle 25 can be easily done by swapping the protrusion 25c and recess 25d and changing the orientation of the connection.

[0036] To close the parasol 1, simply lower the first lower runner 13 and the second lower runner 14 towards the handle. By releasing the release hole 21 of the first lower runner 13 and the release holes 18 and 19 of the second lower runner 14 from the upper release 17, the first lower runner 13 and the second lower runner 14 can be lowered.

[0037] By placing your finger on the ferrule contact portion 22 of the first lower ferrule 13 and lowering it, and bringing the ferrule contact portion 22 against the flange portion 20 of the second lower ferrule 14, the second flick hole 19 of the second lower ferrule 14 is set to overlap with the flick hole 21 of the first lower ferrule 13. The heights of the first support rib connection portion 15 and the second support rib connection portion 16 are at their closest. As you lower the ferrule contact portion 22 of the first lower ferrule 13 further, the second lower ferrule 14 also lowers, pushed by the tip of the ferrule contact portion 22. Once the first lower ferrule 13 and the second lower ferrule 14 have lowered towards the handle, the second flick hole 19 of the second lower ferrule 14 inserts the lower flick 23 into the flick hole 21 of the first lower ferrule 13. In this way, the parasol can be closed.

[0038] To open the parasol 1, raise the second lower ferrule 14. The flange portion 20 of the lower ferrule 14 contacts the ferrule contact portion 22 of the first lower ferrule 13, pushing up the first lower ferrule 13 as well. Raise it until the upper flick 17 enters the flick hole 21 of the first lower ferrule 13 and the first flick hole 18 of the second lower ferrule 14, and the parasol will be in the state shown in Figure 2.
