Description

  The present invention relates to a structure for fixing a parasol, a flag, and a pole for supporting a bag.

  Parasols used in beaches and cafe terraces are installed by piercing the bottom of the parasol on a base fixed with a weight. Generally, the lower end portion is simply fixed by gravity, or is fixed by providing a screw hole on the side surface of the sleeve where the lower end of the pole on the base side is stuck and pressing the side surface of the lower end of the pole with a bolt.

However, when a strong wind blows, the parasol may be pushed upward with a strong force, and this force may cause the lower end of the parasol to escape from the base, causing the parasol to rise by the wind. When the parasol soars like this, it is very dangerous if it hits people or objects because of its weight. Similarly, flags and traps fix the lower end of the pole to the base and may be pulled out by the wind.
This invention makes it a subject to suppress that the bottom end of the pole which fixes a parasol etc. pulls out of a base with a wind in view of such a problem.

In order to solve the above problems, the present invention has the following configuration.
The device according to claim 1 comprises a rod body provided on the lower end side of the pole, the end of which is fixed so as to rotate about a rotation axis perpendicular to the longitudinal direction of the pole, and the tip of the rod body is Fix the pole with one or more locking members whose rotation is restricted to a range from the first rotation position close to the pole to the second rotation position where the tip of the rod body is rotated away from the pole. A fixed base, wherein the pole tip and the locking member pass when the locking member is in the first rotational position, while the locking member is in the second rotational position when the locking member is in the second rotational position. A fixing base in which a hole of a size that the member cannot pass is provided on the upper surface, and a space in which all of the locking member can be accommodated and opened to the second rotation position is formed below the hole. And a part is connected to the rod that constitutes the locking member, An operation portion having a link mechanism formed so that the portion is interlocked with the rotation of the rod body, and the locking member is moved from the state in the second rotation position by operating the other portion. The pole can be operated so as to rotate to a first rotation position, and the other portion is located above the hole in a state where the locking member is in a second rotation position in the space of the fixing base. It is the fixed structure of the pole which has the operation part fixed to.

  According to a second aspect of the present invention, in the fixing structure of the pole, the locking member includes the protruding piece protruding to the lower end of the pole and provided to be movable upward, and the other portion of the operation portion. A closed state holding portion that is held in a state where the protruding piece is moved, and interlocks with the protruding piece, and releases the holding of the other part when the protruding piece moves upward, and the locking member by the elastic body Is further provided with an open state propulsion unit that urges the second rotational position to rotate.

With the configuration as described above, the present invention has the following effects.
The invention according to claim 1, when the lower end of the pole and the locking member are inserted into the hole of the fixing base and the locking member is opened to the second rotation position, the locking member cannot be removed from the hole of the fixing base. It is possible to prevent Paul from getting out due to strong winds. And by operating the other part of the operation part which exists above the hole of a fixed base, a pole can be taken out from a fixed base by making a locking member into a 1st rotation position.
According to the second aspect of the present invention, when the pole lower end and the locking member are inserted into the hole of the fixing base and the protruding piece is pressed against the bottom of the fixing base, the protruding piece moves upward, and the other part of the operation unit Is released, and the locking member is opened by the elastic body so as to be in the second rotational position. Therefore, the locking member can be more reliably moved from the first rotation position to the second rotation position than when the locking member is opened to the second rotation position by gravity or the like.

It is a disassembled front view of the parasol which concerns on embodiment. It is an expanded vertical sectional view which shows the pole lower end of the parasol in the closed state of the locking member which concerns on embodiment. It is an expanded longitudinal cross-sectional view which shows the pole lower end of the parasol in the state which the latching member which concerns on embodiment opened. (A) is a top view of the base part of the parasol which concerns on embodiment, (b) is a longitudinal cross-sectional view of the base part of the parasol which concerns on embodiment. (A) is an expanded longitudinal cross-sectional view which shows the state which inserted the pole lower end of the parasol which concerns on embodiment into a base, (b) is an expanded longitudinal cross-sectional view which shows the state which fixed the pole lower end of the parasol which concerns on embodiment to a base It is.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an exploded view of the parasol X according to the embodiment. The parasol X includes a parasol body P and a base B. In the parasol X, an umbrella S is formed on the upper end side of the pole 10, and an engagement fixing portion R is formed on the lower end of the pole 10. The parasol X can be set in a stable state by the engagement fixing portion R being fitted and fixed to the base B. Since the umbrella S has the same structure as a general parasol, description thereof is omitted.
FIG. 2 shows an enlarged longitudinal sectional view showing a closed state of the engagement fixing portion R, and FIG. 3 shows an enlarged longitudinal sectional view showing an opened state of the engagement fixing portion R. The engagement fixing portion R includes a lower end portion of the pole 10 formed of a pipe body, a locking member 20, an operation portion 30, a closed state holding portion 40, and an open state propulsion portion 50.
The locking member 20 is a rod having a rectangular cross section, and has an end fixed to the lower end of the pole 10 so as to rotate about a rotation axis orthogonal to the longitudinal direction of the pole 10. As shown in FIG. 2, the locking member 20 is rotated from a rotation position A close to the pole 10 and substantially parallel to the pole 10 to a rotation position B perpendicular to the pole 10 as shown in FIG. Is. Note that the rotation of the locking member 20 is restricted so as not to further rotate from the rotation position B. Four locking members 20 are provided symmetrically with respect to the central axis of the pole 10.

The operation unit 30 includes a ring 31, an operation pipe 32, a first link bar 33, and a second link bar 34. The ring 31 and the operation pipe 32 are cylindrical bodies that slide on the outer periphery of the lower end of the pole 10, and the operation pipe 32 is positioned on the ring 31. The operation pipe 32 is set to such a length that it will be exposed from the top of the base B when the lower end of the pole 10 is within the base B, as will be described later. One end of the first link bar 33 is rotatably fixed near the upper center of the locking member 20, and the other end is rotatably fixed to the ring 31. One end of the second link bar 34 is fixed to be rotatable toward the center of the first link bar slightly toward the pole 10, and the other end is fixed to the lower end of the operation pipe 32 to be rotatable. When the operation pipe 32 is pulled upward by such a link mechanism, the locking member 20 is rotated upward to move to the rotational position A as shown in FIG. 2, and is locked when the operation pipe 32 is lowered downward. As shown in FIG. 3, the member 20 rotates downward and moves to the rotational position B.
The open state propulsion unit 50 is configured by a compression spring provided between the ring 31 of the operation unit 30 and the operation pipe 32. As can be seen from a comparison between FIGS. 2 and 3, in the link mechanism of the operation unit 30, when the locking member 20 is closed and in the rotational position A, compared to when the locking member 20 is open and in the rotational position B. Thus, the distance between the ring 31 and the operation pipe 32 is reduced. Therefore, by providing a compression spring between the ring 31 and the operation pipe 32, the interval between the ring 31 and the operation pipe 32 is urged toward the widening direction, so that the locking member 20 is directed toward the rotational position B as a result. It will be energized.

  The closed state holding portion 40 includes a locking hole 32a formed of a vertically long slit-like hole formed on the side surface of the operation pipe 32, and the locking hole 32a of the pole 10 when the locking member 20 is at the rotation position A. The exposed hole 11 formed of a slit-like hole formed so as to overlap with the inner surface, and the inner side exposed from the exposed hole 11 is formed vertically, and is inclined so as to descend inward from the exposed hole 11 to the bottom surface. An engagement plate 42 made of a trapezoidal plate body provided with a notch 42a, a thin plate spring 43 for fixing the engagement plate 42 to the inside of the pole 10 and urging it to be exposed from the exposed hole 11, and an engagement plate 42 A rod body 44 having a slope parallel to the slope of the notch 42a formed at the upper end, a sleeve 45 fixed to the inner wall of the pole 10 for holding the rod body 44 so as to slide in the center of the pole 10, and a rod body 44 A cylinder fixed to the lower end Ranaru protruding piece 46, and a compression spring 47 provided between the projecting piece 46 and the sleeve 45. The rod body 44 is provided with a protrusion 44 a for preventing the rod 44 from being moved upward, and the downward movement by the compression spring 47 is restricted. The position of the protrusion 44a is determined such that when the compression spring 47 pushes the protruding piece 46 downward, the protruding piece 46 slightly protrudes from the lower end of the pole 10 as shown in FIG. Furthermore, the length of the rod body 44 is set to such a length that the upper slope is slightly applied to the notch 42a of the engagement plate 42 when the rod body 44 is in the lower position as shown in FIG. . In this state, the engagement plate 42 projects outward from the exposed hole 11. With this structure, when the operation pipe 32 of the operation unit 30 is raised upward as shown in FIG. 2, the engagement plate 42 protrudes from the locking hole 32a of the operation pipe 32, whereby the operation pipe 32 moves downward. Is regulated. When the protruding piece 46 is moved upward in this state, the rod body 44 moves and the slope of the rod body 44 moves upward in the notch 42a of the engagement plate 42, so that the notch 42a is moved along the inclination. Will be moved to. As a result, the engagement plate 42 is immersed inside, the engagement between the engagement plate 42 and the engagement hole 32a of the operation pipe 32 is disengaged, and the operation pipe 32 is moved downward by the open state propulsion unit 50, and the locking member 20 is moved. As shown in FIG.

  Next, the base B will be described. FIG. 4A shows a plan view of the base B, and FIG. 4B shows a longitudinal sectional view of the base B. The base B is a hollow tank shaped like a hemisphere placed on a flat rectangular parallelepiped, and exhibits a function as a weight when water is put inside. The hemispherical portion is provided with a hole 61 above, and a cross-shaped space 62 is formed below the hole. The cross-shaped space 62 is set to a size and a shape that allow the locking member 20 to move when the locking member 20 moves from the rotation position A to the rotation position B. In addition, the part except the said cross-shaped space of the hemispherical part is connected with the lower flat rectangular parallelepiped, and the water supply port 63 in which the cap for supplying water from the outside is fitted in part is provided. The hole 61 is provided with a sleeve 61a in which a circular hole into which the cylindrical pole 10 is fitted is formed, and a cross is formed so that the locking member 20 at the rotational position A as shown in FIG. 2 can pass therethrough. A notch is formed.

  Next, a method of using the parasol X having the above configuration will be described. First, the case where the parasol body P is installed on the base B will be described. It is assumed that a sufficient amount of water is put into the base B from the water supply port 63. First, as shown in FIGS. 1 and 2, the operation pipe 32 of the operation unit 30 is on the upper side, the engagement plate 42 protrudes from the locking hole 32a of the operation pipe 32, and the operation pipe 32 is restricted from moving downward. And In this state, as shown in FIG. 5A, the cross-shaped space 62 of the base B is formed so that the locking member 20 passes from the hole 61 of the base B through the hole 61 of the base B through the lower end side of the pole 10. Insert into. When inserted, the projecting piece 46 of the closed state holding portion 40 hits the bottom of the space 62, so that the projecting piece 46 moves upward by being pushed in as it is. As a result, the rod 44 moves upward, and the engaging plate 42 interlocking with the rod 44 is inserted into the inside, so that the engagement between the engaging plate 42 and the locking hole 32a of the operating pipe 32 is disengaged. It becomes possible to move downward, and the gap between the operation pipe 32 and the ring 31 is widened by the open state propulsion unit 50, so that the locking member 20 of the base B is provided by the link mechanism of the operation unit 30 as shown in FIG. It automatically opens in the space 62 and reaches the rotational position B. In this state, the locking member 20 cannot be removed from the hole 61 of the base B.

Next, the operation for removing the parasol body P from the base B will be described. First, the operation pipe 32 is pulled upward by holding the upper end of the operation pipe 32 exposed from the upper part of the base B. As a result, the compression spring constituting the open state propulsion unit 50 contracts, and the locking member 20 is closed by the link mechanism of the operation unit 30 to the rotational position A. When the pole 10 is slightly lifted in this state, the protruding piece 46 of the closed state holding portion 40 and the rod body 44 joined thereto are moved downward by the compression spring 47, so that the engagement plate 42 of the closed state holding portion 40 is a thin plate spring. 43 will protrude to the outside. Since the operation pipe 32 is pulled up, the protruding engagement plate 42 and the locking hole 32a of the operation pipe 32 are engaged, and the operation pipe 32 is restricted from moving downward, as shown in FIG. Become. After that, if the pole 10 is pulled out from the hole 61 of the base B, the parasol body P
Can be separated from the base B.

  In addition, although the parasol was illustrated in the said embodiment, the structure demonstrated above is applicable also as a fixing structure of the pole which fixes a flag and a fence.
