Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rope mooring hook that is rotationally inserted below the ground surface and anchors the rope approximately on the ground surface.
[0002]
[Prior art]
Conventionally, iron pegs, wine bottle openers, enlarged wood screws, screw anchors, etc. have been used for mooring ropes, wire ropes, etc. on the surface. Is used to support a tent tension or a column, by driving a steel pile with a ring-shaped or bowl-shaped head with a sharpened lower end into the soil, mooring a rope or the like to the head, Wine bottle opener hooks are, for example, a rope or ring attached to the head of a round bar, such as Japanese Utility Model 465053. The expansion hook of the wood screw is made of resin molding having a wood screw shape and a hook on the top, and is used for mooring a pet rope. On the other hand, the screw anchor supports the utility pole branch line by providing a spiral plate on a special mandrel such as 1-79628, and attaching a lower end of the rod (round bar) to the mandrel, and using a special instrument. Inserting a branch line into a thimble attached to the head of the rod by rotating it downward. For fixing a culture raft, for example, only a spiral plate with several turns of Japanese Utility Model Sho 64-635 is used as a special device. The object was fixed by screwing it into the seabed using a cable and attaching a wire rope or the like to the upper part.
[0003]
[Problems to be solved by the invention]
However, the conventional installation of iron pegs in the soil is hammering in and is easy and easy to work, but requires labor, especially in the axial direction and is unstable. The bottle opener hook is difficult to use in a compacted ground, and the wood screw enlarged hook has an inverted conical shape and is particularly easy to come off in the axial direction. The screw anchor is large and has a huge tension. It is intended for resistance, and the installation part of the spiral plate is complicated, requiring resistance in the soil and increasing costs. Rotating insertion into the soil requires special equipment and large-scale equipment. It is not easy to use lightly and easily, and the mooring part of the rope such as a ring-like or hook-like rope of the head such as the iron pin or the screw anchor is one place for mooring the rope etc. from multiple directions. Was inconvenient. In addition, there has been no hook that increases the tensile resistance by grounding a part of the hook on the ground surface and suppressing horizontal movement or utilizing the overturning rotational stress in the soil. There was not. The present invention intends to solve the above problems.
[0004]
[Means for Solving the Problems]
The present invention is a relatively small rope mooring hook on land, such as outdoor tent tensioning, reinforcement of a shelf for gardening, etc., and mooring of a pet rope, and the following invention is proposed to solve the above problems. According to the first aspect of the present invention, the lower end of a shaft body (round bar or hexagonal bar) made of metal is sharpened, a spiral plate is fixed in proximity to the sharpened portion, and a rotating device ( (Electric impact drills, hand tools, etc.) A hexagonal column that is easy to mount is formed, and below this hook is attached a reverse Ω-shaped hook with hooks on both arms that extend upward, consisting of wire rods. A rope mooring hook provided with a grounding board capable of moving a shaft body provided with a through hole in the body and a compression spring for biasing the grounding board toward the ground surface.
[0005]
According to a second aspect of the present invention, in the rope mooring hook according to the first aspect, a hole for mounting the hook to the shaft body head is provided at the center of the plane made of a strip plate material, and the hook is located above and close to the hole. The rope mooring hook is characterized in that the hook is provided with hooks on both extending arms . By making this hook a wing-like hook made of a band plate material, it is easy to rotate by hand . The hooks may be provided on the outer periphery of the disk, and a plurality of one-armed wing-shaped members provided with ridges may be provided at equal intervals.
[0006]
According to a third aspect of the present invention, in a rope mooring hook that is rotationally inserted under the surface of the resin, a spiral plate is fixed to a sharp lower end portion of a shaft body, and a rotating device is attached to the center of the upper end surface of the shaft body that is a ground portion. And a hook provided with hooks on both arms extending upward to the shaft body adjacent to the hexagonal hole is fixed to the shaft body below the hook of the resin molded body having a fixed configuration. A rope mooring hook provided with a grounding board provided with a through-hole capable of moving the body and a compression spring for biasing the grounding board toward the ground surface . By adopting the above resin molding, it is lightweight, inexpensive and easy to carry and safe.
[0007]
Such a configuration makes it easy to rotate and rotate under the surface with small power or hand rotation of a rotating device, and makes it easy to moor the rope from multiple directions by widening the range of use of the soil and making it difficult to escape from the soil. . Here, the effect of the ground stress of the grounding board and the spiral plate on the oblique tensile load applied to the rope is provided based on FIG. 10 by attaching a grounding board that presses the ground surface with the shaft body movable under the hook. When the rope mooring hook is rotated and inserted into the soil, the grounding board 5 is sunk into the ground by the pressing load W at the lower end of the hook, and the helical plate 2 and the grounding board 5 are in tension due to this consolidation action. When a tensile load (diagonal tensile load) of Q is applied to the hook from the rope 7 with an elevation angle α degrees, the horizontal stress qh (Qcosα) is the overturning rotational stress qh ′ with the point A of the spiral plate 2 as a fulcrum. The grounding board 5 that works on the grounding board 5 but is buried in the ground is tumbled to the spiral plate 2 with the B point of the grounding board 5 serving as a fulcrum due to the blocking action by ground reaction force such as levitation force. qh "works, spiral plate 2, grounding board 5 and shaft Vertical force acting in the direction of the shaft body due to a synergistic effect of increasing resistance stress such as friction stress and support stress in the intermediate ground between the grounding plate and the spiral plate by the overturning rotational stress acting on the body 1 pushing the ground in the rotational direction The rope 7 is strongly supported against the stress qv (Qsin α).
[0008]
In addition, in a relatively soft ground such as embankment, when the shaft body 1 is lifted by soil consolidation by the spiral plate 2 with respect to the vertical stress qv, an intermediate shaft between the hook 3-1 and the grounding board 5 is used. By attaching to the body 1 a compression spring that exerts the grounding effect of the grounding board 5 ( biasing the grounding board 5 toward the ground surface G ), the tension of the spiral plate 2 and the grounding board 5 is maintained, The effect of increasing the tensile resistance due to ground stress is maintained. The grounding board 5 is frictionally fixed to the shaft body 1 at two diagonal points of the clear through hole 5a by the oblique tensile load Q. The grounding board 5 is adapted to the compaction of the ground surface part to prevent the hook and the shaft head from entering the soil, to prevent soiling of rotating parts such as rotating equipment, and to improve the visibility of the hook position. It has the function of ensuring speediness and ensuring the security of rotating equipment.
[0009]
A fourth aspect of the present invention is the rope mooring hook according to any one of the first to third aspects, wherein two hooks are attached to one arm of the hook . 2 and 8 with a spiral shape of about one and a half turns (same function as a spiral) as shown in FIG. 2 and FIG. 8, or two vertical shapes as shown in FIG. For example, when two ropes 4 are attached to one arm, when the rope is moored to the hook, it is possible to tie it quickly and unfasten it very easily.
When each of the hooks is made of an elastic body, the hook 7 is bent by the tensile load of the rope 7 as shown in the use examples of FIGS. loosening prevention is achieved by keeping the stretched state.
