Abstract
A parasol includes a pole of a tension rod-type between a ceiling surface and a floor surface of a building, a lower hub penetrated by the pole and moves in the vertical direction along the pole, an upper hub fixed to a predetermined position of the pole, ribs joined to the upper hub, struts provided with respect to each rib and connecting the ribs and the lower hub, a handle operation unit for moving the lower hub along the pole, and a sheet between the ribs. The pole is divided into an outer pipe, a ceiling pipe attached to an upper side of the outer pipe, and a lower side pipe attached to a lower side of the outer pipe. The length of the pole in the vertical direction is adjustable while the position of the sheet is maintained at a height within a certain range from the floor surface.
Claims14
A parasol comprising:
- a single pole of a tension rod-type between a ceiling surface and a floor surface of a building;
- a lower hub penetrated by the pole and configured to move in the vertical direction along the pole;
- an upper hub fixed to a predetermined position of the pole;
- two or more ribs joined to the upper hub;
- struts provided with respect to each of the ribs and connecting the ribs and the lower hub;
- a handle operation unit for moving the lower hub along the pole;
- and
- a sheet provided between the ribs;
- wherein the pole is divided into at least an outer pipe, a ceiling pipe attached to an upper side of the outer pipe, and a lower side pipe attached to a lower side of the outer pipe,
- wherein the length of the pole in the vertical direction is adjustable while the position of the sheet is maintained at a height within a certain range from the floor surface,
- wherein a pad having a convex connection surface is provided on an upper end of the pole,
- wherein an upper end surface of the pole has a concave connection surface,
- wherein the rotation of the pole is restricted by connecting and engaging the convex connection surface and the concave connection surface.
A parasol comprising:
- a single pole of a tension-rod-type for exerting force between a ceiling surface and a floor surface of a building;
- a sheet that is foldable and has a top view shape of a polygon when in an open state;
- a handle operation unit coupled to the pole;
- an upper arm coupled to the pole and supporting the sheet from an upper side;
- a lower arm having one end attached to the handle operation unit and supporting the sheet from a lower side;
- a support cylinder provided at a center of the sheet on a lower side of the sheet;
- a plurality of ribs extending radially and oscillatably supported by an upper end part of the support cylinder;
- struts having an end in its length direction that oscillatably support an intermediate portion of the lower arm in the length direction and an intermediate portion of the ribs in the length direction;
- a ring member provided at a lower end of the support cylinder, and
- a string member that has one end part coupled to the ring member and another end part coupled to the handle operation unit via the inside of the support cylinder and the inside of the lower arm;
- wherein the sheet is configured to be opened and closed by moving the ring member coupled to the string member upward and downward by performing a winding operation of the string member with the handle operation unit,
- wherein the pole is divided into at least an outer pipe, a ceiling pipe attached to the upper side of the outer pipe, and a lower side pipe attached to the lower side of the outer pipe,
- wherein the length of the pole in the vertical direction is adjustable while the position of the sheet is maintained at a height within a certain range from the floor surface,
- wherein the handle operation unit has a first side surface, a second side surface on the opposite side of the first side surface, a lever portion provided on the first side surface, a lock portion provided on the second side surface for fixing the position of the handle operation unit, and a grip portion interposed between the first side surface and the second side surface,
- wherein the grip portion is configured to be gripped when performing the winding operation,
- wherein the grip portion is provided below the sheet on the side of the sheet.
