BACKGROUND OF THE INVENTION
The present invention is a fence having a fence panel body with an adjustable tilt angle suitable for construction on an inclined ground, and is particularly useful for use in a place requiring a height for the purpose of crime prevention or blocking the line of sight. The present invention relates to a fence with a so-called two-stage pillar specification in which a body is arranged up and down.
[0002]
[Prior art]
DESCRIPTION OF RELATED ART Conventionally, the fence for inclined lands which made the rectangular fence panel body deformable to arbitrary parallelograms according to the inclination angle of a construction place is known.
As shown in Japanese Patent Application No. 2000-272040, the present applicant has proposed a fence that can be constructed according to the inclination angle of the construction site. This fence connects the vertical and horizontal members of the fence panel body so that they can rotate freely, and the fence panel body can be deformed into any parallelogram shape, so that it is possible to construct a fence that matches the inclination angle of the construction site. Is.
[0003]
Since the fence panel body is formed in a predetermined size in advance for the purpose of reducing the manufacturing cost, the fence panel body is arranged up and down at the construction site requiring the height of the fence, and the height is set. A construction method that doubles at once is known. It is a so-called two-stage pillar specification fence, and a support column corresponding to the height of two fence panel bodies is erected, and the fence panel body is mounted on one side of the support column in the vertical direction.
[0004]
However, when the fence panel body is arranged up and down, if the fence panel body is deformed into an arbitrary parallelogram according to the inclination angle of the construction site, the interval between the upper and lower fence panel bodies is changed according to the inclination angle of the fence panel body. Will change. That is, as the inclination angle increases, the interval between the upper and lower fence panel bodies becomes narrower. Conversely, as the inclination angle decreases, the interval between the upper and lower fence panel bodies increases, and in the horizontal state, the interval becomes the maximum width.
[0005]
Therefore, since the interval between the upper and lower fence panel bodies becomes the narrowest at the maximum inclination angle, if the predetermined interval is provided so that the upper and lower fence panel bodies do not contact in the maximum inclination state, the inclination angle is less than that. The upper and lower fence panel bodies do not come into contact.
However, when the inclination angle is equal to or less than the maximum inclination angle, a gap is generated between the upper and lower fence panel bodies, and this gap becomes the maximum size when the fence panel body is horizontally disposed. And this clearance gap worsens the external appearance of a fence, and when using it as a blindfold fence, it was a thing which cannot interrupt | block a gaze completely.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a fence having a good appearance by eliminating a gap generated between the upper and lower fence panel bodies.
[0007]
[Means for Solving the Problems]
As a result of intensive studies in view of such circumstances, the present inventors have arranged a parallelogram-shaped fence panel body whose tilt angle is adjustable up and down, and at the lower end portion of the fence panel body located on the upper side. An upper blindfold member having a vertically projecting vertical wall is attached, a lower blindfold member having an upward projecting vertical wall is attached to an upper end portion of the fence panel body located on the lower side, and a vertically projecting vertical wall of the upper blindfold member and an upper portion of the lower blindfold member The protruding vertical walls are overlapped in the vertical direction, an engagement bent edge is formed at the lower end of the lower protruding vertical wall, an engaged bent edge is formed at the upper end of the upper protruding vertical wall, and the engagement bent edge and the covered edge are formed. The intended purpose is achieved by engaging the engagement bent edge .
[0008]
The engagement bent edge formed at the lower end of the lower side projecting vertical wall, the upper end of the upward-projecting vertical wall forming the engaged bent edge, engaged the Kakarigoori songs edges and the engaged bent edge This ensures that the downwardly projecting vertical wall and the upwardly projecting vertical wall overlap at any inclination angle.
[0009]
[Action]
According to this invention, in a so-called two-stage pillar specification fence in which fence panel bodies are arranged on the upper and lower sides, a gap generated between the upper fence panel body and the lower fence panel body is defined as a vertically projecting vertical wall and an upward projecting vertical wall. Since it can be completely prevented by the wall, the appearance of the fence can be improved, and when used as a blindfold fence, the line of sight from the outside can be completely blocked.

When the fence panel body 3 is deformed into a parallelogram according to the inclination angle of the construction site, the distance between the lower lateral trunk edge 33 of the upper fence panel body 3 and the upper lateral trunk edge 32 of the lower fence panel body 3 is narrowed. This interval decreases as the inclination angle increases.
Although the engaging bent edge 84 of the downward projecting vertical wall 83 and the engaged bent edge 133 of the upward projecting vertical wall 132 are engaged, the lower lateral trunk edge 33 and the lower fence panel of the upper fence panel body 3 are engaged. There is no obstacle to the direction in which the upper horizontal trunk edge 32 of the body 3 is close, and as the inclination angle increases, the overlap margin of the downward projecting vertical wall 83 and the upward projecting vertical wall 132 only increases (see FIG. 2).
[0021]
In the above embodiment, the fence panel body 3 provided with the horizontal trunk edges 32 and 33 has been described. However, without providing the horizontal trunk edges, the upper blind member 8 is directly attached to the horizontal rail members 35 located on the upper and lower sides. And the lower blindfold member 13 may be attached. Furthermore, although the horizontal crosspiece 35 was provided in the fence panel body 3, the vertical crosspiece provided in parallel may be sufficient.
