A screw hole 5 is provided, and a synthetic resin set screw 6 is provided so that the screw hole 5 can be screwed into the female screw hole 5 and the tip of the screw hole 5 can be pressed against the outer surface of the pole 10. 2, a corrugated disk 3 and an inclined upright piece 4 integrally provided around an outer peripheral portion of the corrugated disk 3, and the inclined upright piece 4 is inclined toward the outside. The corrugated disk 3 is formed in an inclined state such that it expands upward, and the corrugated disk 3 protrudes upward. And parts, and a peripheral 設凹 unit to exit bay downward is adopted a means for forming to be disposed alternately at radially.

  Further, in the second aspect of the present invention, means for configuring the outer diameter of the fixed base 1 to be approximately four times or more the outer diameter of the pole 10 is employed.

Therefore, according to the beach umbrella fixing device A of the first aspect of the present invention, the entire fixing device A (particularly, the fixing base 1) has sufficient strength and rigidity, and a strong wind blows. Even at this time, the fixed base 1 is hardly deformed, and the beach umbrella B is hardly inclined. Further, a gap space is hardly generated between the fixed base 1 and the upper sand, and the pressure of the sand sufficiently acts on the fixed base 1 to reliably and stably maintain the immovable state of the beach umbrella B. Become.
Moreover, the fixture A has a simple configuration, is easy to manufacture, is suitable for mass production, can reduce the manufacturing cost, and is economically excellent. In addition, it is excellent in corrosion resistance, easy to handle, and excellent in usability.

  Further, according to the beach umbrella fixing device A of the present invention, the immobilized state of the beach umbrella B can be more reliably and stably maintained.

Hereinafter, the present invention will be described with reference to the illustrated examples.
The present invention is a fixing device A for a beach umbrella, which is mainly attached to a lower portion of a pole 10 of a beach umbrella B and is buried in sand with the lower portion of the pole 10.
The fixing device A according to the present invention includes a substantially cylindrical synthetic resin mounting tube 2 that is externally mounted on the pole 10 and a substantially disk-shaped synthetic resin fixing tube that is integrally connected to the mounting tube 2. And a base 1.
Further, a female screw hole 5 is provided in the mounting cylinder portion 2, and a synthetic resin set screw 6 is provided so that the female screw hole 5 can be screwed into the female screw hole 5 and the tip end thereof can be pressed against the outer surface of the pole 10. It is.
In addition, the fixed base 1 includes a corrugated disk 3 provided around the mounting cylinder 2 and an inclined standing piece 4 integrally provided around the outer peripheral portion of the corrugated disk 3.
In addition, the inclined standing piece 4 is formed in an inclined state such that it expands obliquely upward as it goes outward, and the corrugated disk 3 has a peripherally projecting part that protrudes upward and a downwardly projecting part. Are formed so as to be alternately arranged in the radial direction.

The fixed base 1 is, for example, integrally provided around a lower end edge portion of the mounting tubular portion 2 and is formed in a relatively large substantially flange-like shape. Of the fixture A itself (and the pole 10 of the beach umbrella B) against the force of the wind received by the beach umbrella B and the like.
Note that the fixed base 1 may be provided around the upper end portion or the intermediate portion of the mounting cylinder portion 2.

The outer diameter of the fixed base 1 is preferably about four times or more the outer dimension of the pole 10. That is, the weight of the sand above the fixing base 1 can be increased, and the stationary state of the fixing tool A itself (and the pole 10 of the beach umbrella B) is further maintained against the wind force received by the beach umbrella B. It is easy to handle and easy to handle.
Incidentally, the outer diameter of the fixed base 1 is, specifically, 130 to 150 mm when the outer diameter of the pole 10 is about 23 to 33 mm.

For example, the mounting cylinder 2 is formed in a substantially short cylindrical shape so as to be slidably mounted on the pole 10 of the beach umbrella B, and the fixture A is securely and stably provided at an arbitrary position of the pole 10. It is constituted so that it can be attached to.
The inner diameter of the mounting cylinder 2 is set slightly larger than the outer diameter of the pole 10 so that the mounting cylinder 2 can slide on the pole 10 smoothly.

The corrugated disk 3 is formed so that, for example, a vertical cross section along the radial direction protrudes upward, and is formed in a substantially annular shape on the plane centering on the cylindrical core of the mounting cylindrical part 2. And a circumferential section formed in such a manner that a vertical section along the radial direction protrudes downward, and is formed in a substantially annular shape on a plane centering on the tube core of the mounting tube portion 2. The recesses are formed so as to be alternately arranged in the radial direction, and are formed in a ripple shape having a relatively large undulating waveform in the radial direction.
That is, the fixing base 1 is formed such that the strength and rigidity of the whole fixing base 1 are considerably higher than those of a flat disk-shaped one as in the conventional example. Moreover, it is formed so as to be easily adapted to sand and to maintain a more stable buried state (immobile state).

  The inclined standing piece 4 is formed, for example, to expand obliquely upward from the outer peripheral edge of the corrugated disk 3, and is formed in a substantially annular shape in a plane about the center of the mounting cylinder 2. It is formed so that the sand above the corrugated disk 3 can be reliably caught and the weight of the sand above the corrugated disk 3 can be reliably received. Moreover, when the beach umbrella B is set on the sandy beach, the fixing tool A is formed so as to be easily inserted into the hole dug in the sandy beach.

  The female screw hole 5 is provided, for example, in an appropriate number at an appropriate position on the peripheral wall portion of the mounting cylinder portion 2 and may be any as long as the set screw 6 can be securely and easily screwed. That is, a plurality of female screw holes 5 may be provided so that the state of attachment to the pole 10 may be further strengthened.

  The set screw 6 is desirably one that can be easily tightened with fingers without a tool such as a screwdriver or a spanner, and is a suitable synthetic resin material having sufficient strength and excellent corrosion resistance. It is desirable to be composed of
