Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor screwed into a ground or other object to be fixed, and more particularly to an anchor suitable for fixing a temporary structure such as a tent or a sheet.

[0002]

2. Description of the Related Art Conventionally, as an anchor for fixing a roof beam, one disclosed in JP-A-4-343984 is known. This is one in which one base member is fixed to the ground by two screw anchors, and the lower end of the shed beam is fixed to an anchor bolt provided on this base member. Each of the screw anchors is one rod-shaped, has a screw threaded portion at the lower end and a ring-shaped insertion hole at the upper end, and inserts a separately prepared rotation operation rod into the insertion hole, By turning this by hand,
The screw anchor was screwed into the ground.

[0003]

However, the conventional anchor has the following drawbacks. First, when the anchor is screwed into the ground or pulled out from the ground, it is necessary to insert a rotary operation rod into the insertion hole at the upper end of the anchor and rotate the operation rod, which is difficult to operate. Further, when fixing a rope of a tent or the like to the anchor, the rope must be tied to the anchor in a pulled state, which causes a problem that it takes time to install the tent or the like.

An anchor of the present invention is to provide an anchor that can be easily rotated when screwed into the ground or another object to be fixed, and can easily fix a rope for tensioning a tent, a seat or the like.

[0005]

In order to solve such a problem, the anchor according to claim 1 has an embedded shaft portion formed with a spiral projection on the outer periphery and screwed into an object to be fixed, and the embedded shaft portion. An arm portion formed on the upper end of the arm so as to project laterally, and a rotation operation portion formed on the arm portion. It should be noted that, as the spiral protrusion, a screw (screw) form is preferably used, but the protrusion may be formed in a fragmentary manner along the spiral even if it is not so continuous.

According to a second aspect of the present invention, the arm portion has a structure capable of being folded at the base end portion or the intermediate portion thereof.

In this case, further, as in the invention of claim 3, between the arm portion bent at the base end portion or the intermediate portion and the upper end portion of the embedded shaft portion or the fixed base portion of the arm portion, It is also possible to provide a clamp mechanism that clamps a member to be fixed such as a rope, a wire, a sheet end portion, and a fixing device that fixes the bent arm portion at the clamp position.

Further, according to the invention of claim 4, the rotation operating portion provided at the tip of the arm portion can be bent between an upright position protruding upward and a bending position tilted to the arm side. A clamp portion is provided so as to be bendable integrally with the rotary operation portion, and the clamp portion clamps a rope or other fixed member between the embedded shaft portion or the arm portion. Further, a fixing device for fixing the clamp portion to the embedded shaft portion or the arm portion in the clamped state is provided.

[0009]

In order to screw the anchor of the present invention into an object to be fixed in the ground or on a wall, a ceiling or the like, the arm can be pivoted about the embedded shaft portion by the rotating operation part so that the embedded shaft portion can be easily fixed. It can be screwed in, and conversely, to remove the anchor, the arm portion can be rotated in the reverse direction.

Further, in the anchor in which the arm portion has a bending structure, when the embedded shaft portion is screwed into or out of the ground or the like, the arm portion is rotated and rotated.
When carrying, the entire arm becomes compact by bending the arm.

In the anchor in which the rotary operation portion and the clamp portion are bent, the rotary operation portion at the standing position is held by hand, the arm portion is rotated, and the embedded shaft portion is screwed into the ground, and then the rotary operation portion. The clamped state is maintained by bending the clamp part, clamping a fixed member such as a rope with the clamp part, and fixing the clamp part with a fixing device.
