Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for attaching a strut to be stretched between fence posts.

[0002]

[Prior art]

 For example, to prevent falling into a river, a low fence is not enough, and a fence with a height that is difficult for people to climb over is required. Similar fences and fences will be installed where there is a particular need to prevent crossings on the road. Conventional fences are installed by stretching members on fence posts planted at regular intervals. However, conventionally, fittings and many bolts and nuts were required to attach the spanning members to the fence post. For this reason, special fittings are required on the bends and slopes, and it is difficult to correct the direction, etc., and bolts are tightened under such conditions, resulting in poor workability. It was also pointed out that the only goal was to prevent falls, and the design was left behind, so it was not in harmony with the landscape.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of the above points, and its problem is to greatly facilitate the work of installing a fence and to make it easy to cope with a bent or inclined surface on the installation line. Another object of the present invention is to provide a connecting device for a fencing material that is easily harmonized with the landscape.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention includes a pair of connecting pieces or one of the right and left connecting pieces arranged on the left and right of the fence post, and the connecting pieces are substantially orthogonal to the direction of the stretching material. The joint piece is rotatably connected to the fence post by the mounting shaft in the direction, and the connecting piece is rotatable to the connecting piece using a shaft body in a direction substantially perpendicular to the mounting shaft in order to attach the bridging material to the connection piece. The structure is such that the connecting member is connected to the shaft and the angle is adjustable around two axes that are substantially orthogonal to each other via the joint piece and the connection piece.

[0005]

[Embodiment of the invention]

 The connecting device of the present invention is used to connect the fencing material to the fence post. The fence is, for example, a fall prevention fence, and is composed of fence poles installed at predetermined intervals, a strut spanning material spanned therebetween, and the connecting device.

[0006] The fence post is a means for supporting the laying member, and preferably has a mating portion for attaching the lining member. This counterpart has an outer shape that is structurally and design-wise compatible with the upholstery material and that is in harmony with the landscape of the installation site. As a standard, a stick-shaped material that is hard to bend freely is used. This is because the concept of a fence must satisfy the structure that neither the pillar nor the pierce bends, and in order to prevent the fall, the fence must have the strength to support the load of the fallen person. .

[0007] The connecting device includes a pair of connecting pieces disposed on the left and right of a certain fence post, or one of the right and left connecting pieces. Where a fence is continuous, a pair of connecting pieces is necessary, but at the end or the beginning of the fence, only one connecting piece is sufficient.

The connecting piece is rotatably connected to the fence post by a mounting shaft. The mounting shaft is a means for attaching the connecting pieces to the fence post, and also serves as a means for connecting them when there are two connecting pieces. When only one connecting piece is used, the end processing piece at the end or the beginning of the fence can also serve as the mounting means. Such a mounting shaft will be attached to the fence post from a direction substantially perpendicular to the direction of the pier member.

[0009] The rotatable connection of the connecting piece to the fence post with the mounting axis allows the fence to bend coplanarly at this connecting piece portion. See FIG. Therefore, it is easy to connect the vertical fence post on the slope and the spanning material in the slope direction.

Further, in order to provide another degree of freedom in attaching the bridging member to the connecting piece, the joint piece is rotatably axially connected to the connecting piece using a shaft in a direction substantially perpendicular to the mounting axis. The direction of the joint piece is therefore substantially orthogonal to the direction of the mounting axis, the direction of the laying material, or the direction in which the fence extends, so that the axes of these three directions are related to the orthogonal coordinate axes X, Y, and Z. I can take it.

It is desirable that the joint piece and the bridging member are connected by a fitting configuration including a concave portion and a convex portion that can be male and female fitted. Because of this fitting, the work of joining the joint piece and the bridging member by means such as screwing can be easily performed.

[0012]

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 relates to the first embodiment, and shows the relationship between the fence post 11, the straddling members 12, 12 spanned on the left and right sides thereof, and the respective parts of the coupling device that connects them.

The coupling device 10 includes a pair of left and right connection pieces 21, 21, a mounting shaft 22 for axially connecting the connection pieces 21, 21, and a joint piece 2 connected to the other end of each connection piece 21, 21 using a shaft 23. 4 and 24. The exemplary mounting shaft 22 is mounted on a mounting port 13 provided as a mating part on a side surface of the fence post 11 which faces vertically. Therefore, the shaft 23 is oriented substantially horizontally, and the shaft 23 is orthogonal to the direction of the mounting shaft 22.

The illustrated connecting device 10 has a cap 25 for tightening the pair of connecting pieces 21, 21. When the mounting shaft 22 shown as a bolt is screwed into the mounting port 13, the cap 25 and the mounting base are 14 are connected to the connection pieces 21, 21. The components of the connecting device 10 are made of metal and are made of a material having good weather resistance such as stainless steel, for example.

The illustrated connection pieces 21, 21, cap 25, and the like not only eliminate the sense of incongruity, but are also smartly shaped so as to be in harmony with the fence post 11 to be attached and its pedestal 14. In addition, the shape is maintained such that water and dust hardly collect by shaping. Each of the illustrated connection pieces 21 and 21 has a tapered short arm 26, and the cross shaft portion at the tip of the connection piece 21 and 21 is inserted into a yoke portion 27 for a bearing provided on the joint piece 24. It is designed to achieve both robustness and a large adjustment range.

The joint portion 24 and the bridging member 12 are connected by a male and female fitting 30 in which the tubular portion at the end of the bridging member 12 is a concave portion 28 and the joint piece 24 itself is a convex portion 29. The illustrated joint portion 24 has a cylindrical shape that fits into the annular concave portion 28 and has the above-described yoke portion 27 at the tip, so that a sufficient fitting amount can be obtained. See FIG. This fitting amount may also need to be adjusted at the inclined portion or the bent portion.

The joint piece 24 and the bridging member 12 under the above-mentioned fitting are connected by connecting means 31 indicated by screws. See FIG. The illustrated screw is screwed into a threaded portion 32 provided on the bridging member 12, and is suitably connected to a screw receiving portion 33 provided on the joint piece 24.

FIGS. 5 and 6 show the connecting device 10 according to the second embodiment with respect to the end or the beginning of the fence, having only one connecting piece 21 connected to the fence post 11 by a mounting shaft 22. A portion corresponding to the other connecting piece has a large end cap 35 having no short arm and integrated with the cap. Other configurations may be the same as those in FIGS. 1 to 4, and the detailed description is omitted by using the reference numerals.

Therefore, the connecting device 10 of the present invention is attached to each of the fence posts 11 erected at a predetermined location, and is temporarily fixed by the shaft 22, and the concave portion 28 at the end of the bridging member 12 and the connecting device 10 of the present invention are connected. By fitting the protrusions 27 and screwing them together, it is possible to construct a fence in which the fence post 11 and the bridging member 12 are connected, for example, a fall prevention fence, as shown in FIG. In the case of the example shown in the figure, a bridging member 12 is also attached to the upper end of the fence post 11 in the same direction as above using the connecting device 10 of the present invention. In this case, the mounting opening 13 may be provided vertically toward the lower side of the fence post, and the inclination is adjusted by the shaft 23 instead of the mounting shaft 22 of the first embodiment, and the inclination is adjusted against bending. The adjustment can be made at the mounting shaft 22 instead of the shaft body 23 of the first embodiment.

FIG. 8 shows how the connecting device 10 of the present invention is adjusted in the inclined portion. In the configuration of the first embodiment, the inclination of the connecting pieces 21, 21 is adjusted at the mounting shaft 22. FIG. 9 shows the state of adjustment of the connecting device 10 of the present invention at the bent portion. In the configuration of the first embodiment, the bending of the joint pieces 24, 24 is adjusted at the shaft 23.
