Description

  The present invention relates to a parasol that is installed in outdoor event venues, leisure facilities, parks, and the like and used as rain protection and sun protection for many people.

  Normally, openable parasols installed at outdoor event venues or the like use a publicly-known portable umbrella or parasol. In other words, the upper end of the umbrella bone is pivotally attached to the upper end of the shaft radially and downwardly, and the upper end of the cane is pivotally attached to the lower side of the umbrella bone. The lower end of the cane is pivoted, the seat stretched on the upper surface of the umbrella bone can be opened and closed by the vertical movement of the ring, and the locking piece protruding from the shaft peripheral surface is recessed on the inner peripheral surface of the ring Engage with the groove to maintain the unfolded state of the sheet, and install heavy objects such as concrete blocks at the lower end of the shaft, and install on the ground so that the shaft is kept substantially perpendicular to the ground by the weight of the heavy object Was.

  However, in the case of the above-mentioned parasol, the upper end of the umbrella bone is pivotally attached to the upper end of the shaft, and the seat is opened and closed with a ring that slides along the axis and a cane that is pivotally attached to both ends of the bone. If the seat is deployed by rotating the umbrella bone so that the outer edge of the umbrella bone is located above the upper pivot part, it will be easy for rain to fall under the deployed seat, and the wind will be entangled under the seat and become a strong wind. There is a case where the umbrella bone is broken by being blown by the wind, and the umbrella bone instantaneously hangs down together with the seat due to the momentum of the wind. When such a situation occurs, if a store is opened under the deployed seat, the store will be damaged by the bones and seats drooping due to the wind, and the people who are below will be harmed There was a problem that there was. In addition, when closing the umbrella, the umbrella bone must be rotated downward together with the seat about the pivot at the upper end of the shaft, and the lower end of the umbrella bone and the peripheral edge of the seat contact the opening store or event facility to close the umbrella. There was a problem that it was not possible. In addition, when the umbrella is opened, the seat and the umbrella bone are tilted downward with the axis as the center, so that in rainy weather, a large amount of rainwater falls from the overhead when passing through the position just below the periphery of the deployed seat. There was a problem of being uncomfortable.

  As a measure to improve this, the ring with the inner end of the roof bone pivotally attached is fixed so that it cannot move below the midway position in the longitudinal direction of the tapered column. Both ends are pivotally attached to each other, and a rope is wound around the pulley provided at the upper end and middle of the column and the winch provided at the lower end of the column. An umbrella-shaped roof in which the roof bone configured to move while changing the inclination angle and open and close the seat provided on the upper surface of the roof bone is inclined with respect to the column has been proposed (for example, see Patent Document 1). . However, this umbrella-shaped roof has the effect that the roof bone is kept closed at the same height as when the seat is deployed, and the roof bone and the seat do not contact the store or the like installed below the seat when the roof is closed. Yes, although the improvement in terms of danger can be seen, the roof bone and the seat are tilted with respect to the support column, so the problem of rain water falling from the outer edge of the roof bone and the outer periphery of the seat in the rain is Not improved.

  In view of the above-mentioned problems, a parasol having a shape in which the sheet is developed while being tilted upward with respect to the support column and rainwater is guided in the direction of the support column has been devised. For example, the inner ends of a plurality of bones projecting upward and projecting outward on the cylindrical column are pivoted, a sheet is provided between the upper surfaces of the bones, and the column is loosely inserted into the reverse cylinder, Each pulley is provided, and a rope is wound between these pulleys. The tilt angle of the support bone (cane) is reduced by indexing the rope, the parasol is opened, and the support bone is raised by loosening the rope. Enlarge the umbrella to close the umbrellas, so that the rain that falls on the upper surface of the seat is collected on the upper surface of the tent in the direction of the column, and flows down the hollow part of the column from the upper end opening of the column and drains into the ground. Some are configured (see, for example, Utility Model Document 1).

  The Parlanle described in the above-mentioned utility model document 1 has an effect that rainwater does not fall from the outer edge of the bone or the outer periphery of the seat, and a person entering and leaving the seat does not receive a large amount of rainwater from the overhead. However, the supporting bones and the return cylinders that support the bones and the seats are visually recognized through appearance, and are unsightly as parasols that require fashionability to be installed at event venues, and have aesthetic problems. In addition, the rope is moored to a clasp provided on the outer surface of the reverse barrel to fix the bone in place and hold the seat in a certain unfolded state. It could be used for firewood and had the problem of being extremely dangerous.

Therefore, the inventor of the present application connects the outer end of the chain that passes through the opening of the cylindrical body that opens at a position higher than the pivoting portion of the inner end of the bone to the upper surface side of the bone, and moves the seat by moving the chain located above the seat. In addition, the pivoting part is arranged inside the rain catch that is connected to the upper end of the hollow column so that even if a large amount of rainwater is present, the hollow column is completely and accurately not overflowed. Invented a parasol that can be drained into the outside through a hollow portion, and applied for a patent as Japanese Patent Application No. 2004-234922.
