Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a post mounting bracket. Specifically, the present invention relates to a support mounting bracket for attaching to a support used in the agricultural and fishing fields, for example.

Supports are used in a variety of fields. For example, in the agricultural field, supports are used to support vegetables that produce large fruits or vines, and supports are used to support electric fences to protect crops from pests. is sometimes used.

Furthermore, for example, in the livestock industry, posts are used in pasture fences for managing livestock grazing.
Furthermore, for example in the fishing industry, props are used in the cultivation of seaweed.

For example, there are two types of seaweed farming: ``pole-type seaweed farming,'' which involves setting up poles on the ocean floor and stretching seaweed nets near the sea surface, and ``floating seaweed farming,'' which involves floating seaweed nets on the sea surface by connecting them to buoys.

The tidal difference in Japan's Ariake Sea is up to 6 meters, and the Ariake Sea also has vast tidal flats, so stilt-type seaweed cultivation is popular along the coast of the Ariake Sea.
This is because tidal flats have shallow water depths, making it easy to build pillars, and taking advantage of the tidal difference of up to 6m, soaking seaweed in seawater at high tide allows the seaweed to absorb nutrients from the seawater, and raising the seaweed from the sea surface at low tide. This is because by exposing the seaweed to sunlight, it can store flavor in the seaweed and make it less susceptible to diseases.

In addition, in prop-type seaweed cultivation, as described in Patent Document 1, for example, a rope is tied to the prop and a seaweed cultivation net is attached to the prop.

That is, as shown in FIG. 6, in the conventional prop-type seaweed cultivation, one end of a hanging rope 103 for hanging a seaweed net 102 is attached to a column 100.
Further, the other end of the hanging rope 103 is attached to a rope 102A that constitutes the seaweed net 102.
Moreover, FIG. 6 shows a state in which the seaweed net 102 rises from the sea surface at low tide, and the seaweed 104 attached to the rope 102A is exposed to the air.

Japanese Patent Application Publication No. 2001-28958

However, as described in Patent Document 1, the method of attaching the nori cultivation net to the support by tying a rope to the support requires removing the nori cultivation net from the support or adjusting the height of the installation position of the nori cultivation net. In such cases, the rope must be untied, the height of the installation position adjusted, and the rope tied to the post by hand again.

Also, when tying a rope to a post, it must be tied firmly so that the rope does not easily come off or shift from the post due to the force of the waves.

In addition, not only in the fishing industry such as seaweed farming, but also in the agricultural field, for example, equipment is attached to the posts of electric fences and conductive wires are attached to the equipment, but if such equipment comes off the posts, it can be dangerous. The conductor wires also came off, causing problems with the electric fence's functionality.

Therefore, it is easy to install and remove from the support, and ropes can be easily connected, and once it is attached to the support, the support can easily shift in the direction in which it extends or come off from the support due to external forces such as ropes. There was a need for a device that would be difficult to attach to a post.

The present invention was devised in view of the above points, and provides a support for mounting a support that, when attached to a support, is difficult to move in the direction in which the support extends, is difficult to come off from the support, and is easy to adjust the mounting position. The purpose is to provide metal fittings.

In order to achieve the above object, the support post mounting bracket of the present invention includes a main body portion having a through hole formed therein and a peripheral region located around the through hole, and a main body portion having a peripheral area located around the through hole. It protrudes by a predetermined length from the surrounding area of the main body portion with its center directed toward an imaginary central axis passing in a direction substantially perpendicular to the radial direction of the through hole, and approximately relative to the radial direction of the through hole. and a protruding piece that can be elastically deformed in orthogonal directions.

Here, with the main body portion having a through hole formed therein and a peripheral area located around the through hole, the strut mounting bracket of the present invention can be attached to the strut simply by arranging the strut in the through hole. The mounting position relative to the pillar can be determined freely.
Further, when the support post is placed in the through hole, since the main body surrounds the support support, movement of the support support fitting of the present invention in a direction substantially perpendicular to the direction in which the support support extends can be suppressed.

Further, the main body part has a through hole formed therein and has a peripheral area located around the through hole, and a virtual central axis passing through the center of the through hole of the main body part in a direction substantially perpendicular to the radial direction of the through hole. The protruding piece protrudes from the peripheral area of the main body by a predetermined length toward the main body, so that the tip of the protruding piece comes into contact with a support placed in the through hole of the main body, allowing the main body to be attached to the support. Furthermore, the support mounting bracket of the present invention can function as a flange protruding from the surface of the support to increase its strength by the peripheral area surrounding the through hole of the main body and the protruding piece.

Here, "predetermined length" means a length shorter than the radius of the through hole.

In addition, the protruding piece can be elastically deformed in a direction substantially perpendicular to the radial direction of the through-hole, so that when the post mounting bracket of the present invention is attached to the post, the tip of the protruding piece can be attached to the surface of the post. Even if the main body tries to move in the direction in which the struts are in contact with each other, the elastic force of the protruding piece is generated, making it difficult for the main body to move.

Further, in the strut mounting bracket of the present invention, the main body has at least two curved members, and the curved members are rotatably and detachably connected to each other to form a through hole. It can be configured as follows.

In this case, since the diameter of the through hole can be changed, it is possible to adapt to supports having various outer diameters.

Furthermore, in the strut mounting bracket of the present invention, the protruding piece has a longer length than the first protruding piece in the same direction as the radial direction of the through hole, and the length of the protruding piece is longer than the first protruding piece. The second protruding piece may have a length shorter in the same direction as the circumferential direction of the through hole than the length of the protruding piece in the same direction as the circumferential direction of the through hole.

In this case, the second protruding piece easily exerts elastic force, while the first protruding piece easily exerts a force for holding the support column.
Furthermore, by bending the first projecting piece in a direction substantially perpendicular to the radial direction of the through hole, it is possible to adapt to supports having various outer diameters.
Further, the second protruding piece is bent in a direction substantially perpendicular to the radial direction of the through hole to adjust the inclination angle of the second protruding piece with respect to the radial direction of the through hole. The elastic force exerted by the part can be adjusted.

Further, in the strut mounting bracket of the present invention, the length of the second protruding piece in the same direction as the circumferential direction of the through hole is gradually shortened toward the tip of the second protruding piece. can do.

In this case, the spring action of the second projecting piece becomes effective and efficient.

Further, in the strut mounting bracket of the present invention, the tip of the first projecting piece may be curved concavely toward the virtual central axis passing through the through hole.

In this case, it becomes easier for the tip of the first protruding piece to come into stable contact with the curved surface of the support.

Furthermore, in the strut mounting bracket of the present invention, the tip of the second projecting piece may be curved in a convex manner toward the virtual central axis passing through the through hole.

In this case, the length of the tip of the second protruding piece in the same direction as the circumferential direction of the through hole is longer than when the tip of the second protruding piece is curved concavely toward the virtual central axis passing through the through hole. Since the length can be shortened, the second projecting piece can be easily elastically deformed.

Further, in the support post mounting bracket of the present invention, a plurality of peripheral through holes may be formed in the peripheral region of the main body portion in a manner that is arranged in the circumferential direction of the through hole.

In this case, for example, ropes or other elements can be attached to the peripheral through-holes.

When the strut mounting metal fitting according to the present invention is attached to a strut, it is difficult to move in the direction in which the strut extends, and it is difficult to come off from the strut, making it easy to adjust the mounting position.

Further, the virtual central axis 11 passes through the center of the through hole 21 in a direction substantially perpendicular to the radial direction of the through hole 21 .
Further, the virtual central axis 11 is a straight line without substance.

Further, the main body portion 20 has a peripheral region 22 , and the peripheral region 22 is a region located around the through hole 21 .

Moreover, the main body part 20 has a curved first curved member 20A and a curved second curved member 20B.

Further, a connecting hook 23 protruding from the surface of the first curved member 20A is provided on the other end side opposite to the one end side of the first curved member 20A.
Here, the connecting hook 23 has a portion extending in a direction substantially perpendicular to the surface of the first curved member 20A, and a portion extending from this portion in a direction substantially parallel to the surface of the first curved member 20A. The first curved member 20A is configured with a portion extending toward one end side of the first curved member 20A.
That is, the connecting hook 23 has an inverted L shape, as shown in FIG. 1(b).

Further, a connecting hole 24 is formed to penetrate through the other end side of the second curved member 20B, which is the opposite side to the one end side.
Here, the size of the connection hole 24 is such that the connection hook 23 can be inserted therethrough.

Therefore, the other end side of the first curved member 20A and the other end side of the second curved member 20B are overlapped and the connecting hook 23 is inserted into the connecting hole 24 to connect them as shown in FIG. 1(b). By fitting the hook 23 into the edge of the connection hole 24, the other end side of the first curved member 20A and the other end side of the second curved member 20B can be removably connected.

Then, as shown in FIG. 1(a), the other end side of the first curved member 20A and the other end side of the second curved member 20B are removably connected, so that a through hole 21 can be formed. .
Therefore, the bending direction of the first bending member 20A and the bending direction of the second bending member 20B correspond to the circumferential direction of the through hole 21.

Furthermore, a plurality of peripheral through holes 25 are formed in the peripheral region 22 of the main body portion 20, that is, in the first curved member 20A and the second curved member 20B, arranged in the curved direction.
Furthermore, when the post mounting fitting 10 of the present invention is attached to a post, for example, a rope can be passed through the peripheral through hole 25 to connect the post mounting fitting 10 of the present invention to the post or other member.

Further, the main body portion 20 can have more curved members, for example, four to six curved members, and each curved member can be rotatably and detachably connected to each other to form a through hole.

Further, a plurality of notches 26 are formed in the peripheral region 22 of the main body portion 20 and extend in the same direction as the radial direction of the through hole 21 .

Further, the support post mounting bracket 10 of the present invention includes a protruding piece portion 30.
Here, the protruding piece 30 extends a predetermined length from the peripheral region 22 of the main body 20 toward the virtual central axis 11 passing through the center of the through hole 21 of the main body 20, that is, shorter than the radius of the through hole 21. It sticks out in length.
Further, the protruding piece portion 30 can be elastically deformed in a direction substantially perpendicular to the radial direction of the through hole 21 .

Furthermore, the protruding piece 30 includes a first protruding piece 31 and a second protruding piece 32.
Further, the second protruding piece 32 has a longer length in the same direction as the radial direction of the through hole 21 than the first protruding piece 31 .
Moreover, the length of the second projecting piece 32 in the same direction as the circumferential direction of the through hole 21 is shorter than the length of the first projecting piece 31 in the same direction as the circumferential direction of the through hole 21 .

Further, the length of the second projecting piece 32 in the same direction as the circumferential direction of the through hole 21 gradually becomes shorter toward the tip of the second projecting piece 32.

Further, as shown in FIG. 1A, the tip of the first protruding piece 31 is curved in a concave shape toward the virtual central axis 11 passing through the through hole 21. As shown in FIG.
Further, as shown in FIG. 1A, the tip of the second projecting piece 32 is curved in a convex manner toward the virtual central axis 11 passing through the through hole 21. As shown in FIG.

Furthermore, a plurality of first protruding pieces 31 and second protruding pieces 32 each protrude from the peripheral region 22 of the main body 20 .
Further, the first protruding piece 31 and the second protruding piece 32 are located between the notch 26 and the notch 26, respectively.

Next, the roles of the first protruding piece 31 and the second protruding piece 32 when the post mounting bracket 10 of the present invention is attached to a post will be explained.

When the strut mounting bracket 10 of the present invention is attached to a strut, the first protruding piece portion 31 comes into contact with the surface of the strut, and the strut mounting bracket 10 of the present invention moves in the radial direction mainly due to external force. is regulated in a rigid body (rigidity).
Moreover, as shown in FIG. 1(a), the diameter of the first virtual circle 12, which has no substance and is formed by connecting the tips of the first projecting pieces 31, is either the same as the diameter of the support or the diameter of the support. slightly larger than

Furthermore, when the support post attachment fitting 10 of the present invention is attached to the support support, the second projecting piece 32 comes into contact with the surface of the support support while generating an elastic force due to a predetermined deflection. The second protruding piece 32 elastically restricts the movement of the column mounting bracket 10 of the present invention in the direction in which the column extends (axial direction) mainly due to external force.
In addition, as shown in FIG. 1(a), the diameter of the insubstantial second virtual circle 13 formed by connecting the tips of the second protruding pieces 32 is adjusted by an amount corresponding to a predetermined deflection of the support. smaller than the diameter of

In the strut mounting bracket 10 of the present invention, the main body 20 does not necessarily have the first curved member 20A and the second curved member 20B. The member 20A and the second curved member 20B do not necessarily have to be rotatably and detachably connected to each other.
For example, the main body can have an integral configuration that cannot be opened or closed. That is, for example, a through hole may be formed in the central region of a circular metal plate.

However, if the main body part 20 has a plurality of curved members in this way, the diameter of the through hole 21 can be changed, so that it can be adapted to supports having various outer diameters, which is preferable.

Furthermore, the method of connecting the plurality of curved members to each other does not necessarily have to be through the rivets 40.
For example, by connecting one end of the curved members to each other by burring caulking instead of a rivet, and connecting the other ends to each other by a combination of a connecting hook and a connecting hole, the curved members can rotate freely with respect to each other, and Detachably connected.

Furthermore, in the support post attachment fitting 10 of the present invention, the protruding piece 30 does not necessarily need to be composed of the first protruding piece 31 and the second protruding piece 32.

However, if the protruding piece 30 is composed of the first protruding piece 31 and the second protruding piece 32, it is preferable from the following points.
That is, the second protruding piece 32 can easily exert elastic force, while the first protruding piece 31 can easily exert a force for holding the column, which is preferable.
Further, it is preferable that the first projecting piece 31 is bent in a direction substantially perpendicular to the radial direction of the through hole 21, so that it can be adapted to supports having various outer diameters.
Further, the second projecting piece 32 is bent in a direction substantially perpendicular to the radial direction of the through hole 21 to adjust the inclination angle of the second projecting piece 32 with respect to the radial direction of the through hole 21. This is preferable because the elastic force exerted by the second protruding piece portion 32 can be adjusted.

In addition, in the strut mounting bracket 10 of the present invention, the length of the second protruding piece 32 in the same direction as the circumferential direction of the through hole 21 does not necessarily have to be gradually increased toward the tip of the second protruding piece 32. It doesn't have to be shorter.

However, if the length of the second protruding piece 32 in the same direction as the circumferential direction of the through hole 21 gradually becomes shorter toward the tip of the second protruding piece 32, the second protruding piece This is preferred because the spring action of the portion 32 is effective and efficient.

Furthermore, in the support post attachment fitting 10 of the present invention, the tip of the first projecting piece 31 does not necessarily have to be concavely curved toward the virtual central axis 11 passing through the through hole 21.

However, if the tip of the first protruding piece 31 is curved concavely toward the virtual central axis 11 passing through the through hole 21, the tip of the first protruding piece 31 will be stable on the curved surface of the support. This is preferable because it makes it easier to come into contact with the object.

Furthermore, in the support post attachment fitting 10 of the present invention, the tip of the second projecting piece 32 does not necessarily have to be curved convexly toward the virtual central axis 11 passing through the through hole 21.

However, if the tip of the second protruding piece 32 is curved convexly toward the virtual central axis 11 passing through the through hole 21, The length of the tip of the second protruding piece 32 in the same direction as the circumferential direction of the through hole 21 can be made shorter than when the second protruding piece 32 is curved concavely toward the central axis 11. It is preferable because it is easy to elastically deform.

Furthermore, in the support post attachment fitting 10 of the present invention, the peripheral through hole 25 does not necessarily have to be formed in the peripheral region 22 of the main body portion 20.

However, if a peripheral through-hole 25 is formed in the peripheral region 22 of the main body 20, a rope or the like can be passed through the peripheral through-hole 25 to connect the pole mounting bracket 10 of the present invention to the pole or other member. This is preferable because it is possible to easily bridge a rope between the columns using the column mounting bracket 10 of the present invention.

Further, although the shape of the outer peripheral edge of the main body portion 20 illustrated is a curved shape, it does not necessarily have to be such a shape, and may be, for example, a polygonal shape composed of corners and straight lines.

FIG. 2 is a partial schematic diagram illustrating an example of an open state of the strut mounting bracket to which the present invention of FIG. 1 is applied.
For example, the first curved member 20A or the second curved member 20B is moved in the direction of increasing the area of the overlapped portion of the other end side of the first curved member 20A and the other end side of the second curved member 20B. When at least one of them is moved, the connection hook 23 and the edge of the connection hole 24 are disengaged from each other.

Then, in the state where the fitting is released, the connecting hook 23 is pulled out from the connecting hole 24, and one end side of the first curved member 20A and one end side of the second curved member 20B connected by the rivet 40 are connected. When the first curved member 20A and the second curved member 20B are rotated about the center, the support post attachment fitting 10 of the present invention will be in an open state, as shown in FIG.
When attaching the support post attachment fitting 10 of the present invention to a support post, the support support fitting 10 of the present invention is installed in an even wider open state.

FIG. 3 is a schematic perspective view showing an example of a strut mounting bracket to which the present invention is applied.

As shown in FIG. 3, the plurality of second protruding pieces 32 of the post mounting bracket 10 of the present invention are bent in a direction substantially perpendicular to the radial direction of the through hole 21, and 21 in a diagonal direction and in opposite directions.

That is, one second protruding piece 32 is bent and protrudes diagonally upward with respect to the radial direction of the through hole 21, and the second protruding piece 32 In the bending direction of the curved member 20B, the other second protruding piece 32 located next to the one second protruding piece 32 across the first protruding piece 31 is bent, and the through hole 21 is bent. It is in a state of protruding diagonally downward with respect to the radial direction.

Further, as shown in FIG. 3, the first protruding piece 31 of the post mounting bracket 10 of the present invention also extends approximately perpendicular to the radial direction of the through hole 21 when the outer diameter of the post is large. The support is bent in the direction and protrudes in a direction diagonal to the radial direction of the through hole 21, thereby making it easier to arrange the support in the through hole 21.

Further, the plurality of second protruding pieces 32 can also be in a state of protruding in a direction substantially perpendicular to the radial direction of the through hole 21.

Next, the manner of use of the strut mounting bracket of the present invention will be explained.
FIG. 4 is a schematic diagram illustrating an example of a usage state of the strut mounting bracket to which the present invention is applied.
Further, FIG. 5 is a schematic partial enlarged cross-sectional view showing an example of how the first protruding piece and the second protruding piece of the post mounting metal fitting to which the present invention is applied come into contact with the post.

FIG. 4 shows a state in which the support post attachment fitting 10 of the present invention is attached to a support post 60 made of glass fiber.
Here, the support 60 is one used in support-type seaweed cultivation.

As shown in FIG. 4, the post mounting bracket 10 of the present invention is attached near the upper end of the post 60.

Further, one end of a hanging rope 63 for hanging the seaweed net 62 is passed through the peripheral through-hole 25 of the main body 20 provided in the post mounting bracket 10 of the present invention.
Further, a ball knot is provided at one end of the hanging rope 63 to prevent the one end from falling out from the peripheral through hole 25.
Further, the other end of the hanging rope 63 is attached to a rope 62A that constitutes the seaweed net 62.

In addition, as shown in FIG. 3, in the post mounting bracket 10 of the present invention attached to the post 60, the first protruding piece 31 and the second protruding piece 32 are bent to form a diameter of the through hole 21. It is made to protrude in a direction diagonal to the direction.

Here, since the seaweed net 62 is suspended by a hanging rope 63, the position of the seaweed net 62 can be moved up and down by the length of the hanging rope 63.

FIG. 4 shows a state in which the seaweed net 62 rises from the sea surface at low tide and the seaweed 64 attached to the rope 62A is exposed to the air. However, as the tide shifts from low tide to high tide, the sea level rises and the seaweed After the net 62 contacts the sea surface, the seaweed net 62 also rises as the sea level rises.
Further, the attachment position of the support post attachment fitting 10 of the present invention, to which one end of the hanging rope 63 is attached, to the support support 60 is adjusted as appropriate so that the seaweed net 62 is in contact with the sea surface at high tide.

In addition, as shown in FIG. 5, in the post mounting bracket 10 of the present invention attached to the post 60, the plurality of second protruding pieces 32 are arranged in a direction substantially orthogonal to the radial direction of the through hole 21; That is, the struts 60 are bent in the direction in which they extend, so that they protrude in directions diagonal to the direction in which the struts 60 extend, and in directions opposite to each other.
Therefore, even if the tip of the second projecting piece 32 comes into contact with the surface of the column 60 and the main body 20 tries to move in the direction in which the column 60 extends, the elastic force of the second projecting piece 32 is generated. The main body part 20 is difficult to move.

As described above, the post mounting bracket 10 of the present invention includes the main body 20, the through hole 21 is formed in the main body 20, and the main body 20 has a peripheral area 22 located around the through hole 21. Therefore, the post mounting bracket 10 of the present invention can be attached to the post 60 by simply arranging the post 60 in the through hole 21, and the mounting position with respect to the post 60 can be freely determined.
Further, when the support 60 is placed in the through hole 21, since the main body 20 surrounds the support 60, the support 60 of the present invention can be attached to the support 60 in a direction substantially perpendicular to the direction in which the support 60 extends. Movement can be suppressed.

Furthermore, since the post mounting bracket 10 of the present invention includes the second protruding piece 32, when the post mounting bracket 10 of the present invention is attached to the post 60, the second protruding piece is attached to the surface of the post 60. Even if the tips of the sections 32 come into contact and the main body 20 tries to move in the direction in which the struts 60 extend, the elastic force of the second projecting piece 32 is generated, making it difficult for the main body 20 to move.

Therefore, when the strut mounting bracket 10 of the present invention is attached to the strut 60, it is difficult to move in the direction in which the strut 60 extends, and it is difficult to come off the strut 60, making it easy to adjust the mounting position.

Furthermore, although the explanation has been given with reference to an example in which the prop mounting bracket of the present invention is attached to a prop in seaweed cultivation, the field in which the prop mounting bracket of the present invention can be used is not limited to the fishery field such as seaweed cultivation. Of course.
For example, in the agricultural field, the post mounting bracket of the present invention can be attached to a post used for a fence surrounding farmland.
