Abstract

[Problem] To provide a parasol that can easily switch between a normal parasol state and a state that generates wind like a fan. [Solution] The parasol has a central shaft, a plurality of umbrella fabric pieces in the shape of a roughly isosceles triangle having a first side and a second side of equal length, a first rib provided along the first side, a second rib provided along the second side, a first support rib supporting the first rib, a second support rib supporting the second rib, an upper ferrule having a first upper ferrule connection part that rotatably supports one end of the first rib, and a second upper ferrule connection part that rotatably supports one end of the second rib, a first lower ferrule that rotatably supports one end of the first support rib, and a second lower ferrule that rotatably supports one end of the second support rib, the first lower ferrule and the second lower ferrule being movable along the length direction of the central shaft, and the second lower ferrule being able to switch positions relative to the first lower ferrule.

Description

This invention relates to a parasol that has a function of blowing air like a fan. Parasols are effective in blocking sunlight and preventing sunburn and overheating. Due to recent global warming, parasols are recommended as a measure against heatstroke in the summer, and parasols for men are also available. Patent Document 1 describes a parasol and beach umbrella with an added ventilation mechanism. By incorporating a fan into the umbrella's structure, it is possible to lower the user's body temperature and prevent heat buildup inside the umbrella. Japanese Patent Publication No. 2009-39492 This is a plan view of a parasol.This is a front view of the same object.This is a front view showing the top potter's wheel.This is a front view showing the first lower potter's wheel.This is a front view showing the second lower potter's wheel.This is a front view showing the first and second lower potter's wheels combined.This is a conceptual diagram illustrating the function of a parasol.This is a front view showing a parasol in a fan-like state.This is a front view showing an example of a handle.This is a left side view showing the handlebar area.This is a front view showing the handle in the parasol position.This is a front view showing the handle in the fan mode. This invention will now be described in terms of embodiments. Figure 1 is a plan view of a parasol, and Figure 2 is a front view thereof. The parasol 1 comprises a central shaft 2 and a canopy. The canopy is divided into several pieces 3. The number of divisions is arbitrary, but in this example, it is divided into eight pieces 3. Each piece 3 is approximately isosceles triangular in shape, with a first side 4 and a second side 5 of equal length. The side closer to the central shaft 2 does not necessarily have to be a perfect corner; it may have a rounded corner. In the umbrella fabric 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. Furthermore, a first support rib 8 is provided in the middle of the first rib to support it, and a second support rib 9 is provided in the middle of the second rib to support it. An upper ferrule 10 is provided near the upper end of the central shaft 2. Figure 3 is a front view showing the upper ferrule. The upper ferrule 10 has a first upper ferrule connection part 11 that rotatably supports one end of the first rib 6, and a second upper ferrule connection part 12 that rotatably supports one end of the second rib 7. If there are eight umbrella fabric pieces 3, there are eight first ribs 6 and eight second ribs 7, so eight first upper ferrule connection parts 11 and eight second upper ferrule connection parts 12 are provided. The first upper wheel connection part 11 and the second upper wheel connection part 12 are located in close proximity, but the second upper wheel connection part 12 is slightly lower than the first upper wheel connection part 11. Furthermore, even along the outer circumference, the first upper wheel connection part 11 and the second upper wheel connection part 12 are positioned slightly offset from each other, so that when viewed from above, the second upper wheel connection part 12 is slightly further forward in the clockwise direction. By offsetting the first upper wheel connection part 11 and the second upper wheel connection part 12 in this way, interference between the first bone 6 and the second bone 7, and between the first support bone 8 and the second support bone 9 can be prevented or reduced. Below the upper potter's wheel 10, there is a first lower potter's wheel 13 that rotatably supports one end of the first support bone 8, and a second lower potter's wheel 14 that rotatably supports one end of the second support bone 9. Figure 4 is a front view showing the first lower potter's wheel, Figure 5 is a front view showing the second lower potter's wheel, and Figure 6 is a front view showing the first and second lower potter's wheels combined. The second lower potter's wheel 14 is a cylindrical hollow member through which the central rod 2 passes. A second support bone connection portion 16 is provided on the outer circumference, which rotatably supports one end of the second support bone 8. An upper stopper, an upper flick 17, is provided on the upper part of the central rod 2, allowing it to move freely outside the rod. Holes for the upper flick 17 to enter and exit are provided at two locations on the upper and lower parts of the second lower potter's wheel 14. The upper hole is designated as the first flick hole 18, and the lower hole as the second flick hole. A wide flange portion 20 is formed at the lower end of the second lower potter's wheel 14. The first lower wheel 15 is also a cylindrical hollow member, with a hole inside through which the second lower wheel 14 passes. A first support bone connection part 15 is provided on the outer circumference, which rotatably supports one end of the first support bone 7. A single re
