Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a fence used for blindfolding or security.

[0002]

2. Description of the Related Art A fence of this type is constructed by mounting a shielding body having a blinder or the like between a pair of vertical or horizontal rails on a support between standing supports at predetermined positions via mounting brackets. Is generally known.

[0003]

According to such prior art, since the shield is only supported by the columns at both left and right positions, the rigidity of the fence after being attached to the columns is limited by the shield itself. In particular, in the case of a shield having a large width, twisting and warping appear remarkably in the shield, and the aesthetic appearance and rigidity of the fence are poor. Furthermore, when attaching a shield to a support | pillar, it was necessary to perform position alignment, such as a horizontal and a height, in the state which supported the large shield by hand, and the construction work was very complicated.

[0004]

The present inventors have made intensive studies to solve such a problem, and as a result, a fence frame which is erected at a predetermined position where a vertical beam and a horizontal beam are framed in a rectangular shape. And a shield attached to an opening of the fence frame and having a thickness smaller than that of the fence frame. An upper engaging edge is formed at an upper edge of the crosspiece, a downwardly engaged groove formed at a lower end of the shield is engaged with the engaging edge, and an upper end of the shield is engaged with the engaging edge. The intended problem has been solved by fixing at least the upper edge of the shield to the fence frame via a bracket having an L-shaped cross section at a position opposite to the edge.

[0005]

According to this invention, since the shield is attached to the fence frame framed in a rectangular shape by the vertical rail and the horizontal rail via the bracket having an L-shaped cross section, the shield is formed by the fence frame and the fence frame. The shape is reinforced by the bracket having an L-shaped cross section, and the strength of the fence itself after construction is increased. In a state in which the downwardly engaged groove of the lower end of the shield is engaged with the engaging edge of the lower horizontal rail and the upper end is locked to the locking edge of the upper horizontal rail, the shield is positioned from the position opposite to the locking edge. Since the edge is attached to the fence frame via an L-shaped bracket, there is no need to hold the shield by hand when attaching the shield to the fence frame, greatly improving workability. I do.

[0006]

1 to 3 show an example in which the fence of the present invention is used as a blind fence in a two-stage garage. In the figure, reference numeral 1 denotes a fence frame which is framed by an upper horizontal rail 2, a lower horizontal rail 3, and left and right vertical rails 4 formed of an aluminum material or the like, and has a shield mounting opening 5 formed therein. It is erected at the installation location.

A lower edge of the upper horizontal rail 2 is integrally formed with a locking edge 21 extending downward into the opening 5 and an upper edge of the lower horizontal rail 3 is similarly engaged with the upper edge. 31 are formed integrally. On the other hand, the shield 6 attached to the opening 5
Is formed in substantially the same shape as the opening 5, and the thickness thereof is smaller than the thickness of the fence frame 1. On the lower end surface of the shield 6, a pair of downwardly engaged grooves 7, 7 having a substantially inverted V-shaped cross section are formed in parallel over the entire width of the shield 6 in the width direction.

When the shield 6 having the above structure is attached to the fence frame 1, first, the engaging edge 31 formed on the lower horizontal rail 3 and the engaged groove 7 of the shield 6 are engaged. With the mating edge 31 and the engaged groove 7 engaged, the shield 6 is rotated around the lower end of the shield 6 to position the shield 6 in the opening 5. At this time, as shown in FIG. 2, a gap 10 is formed between the upper end of the shield 6 and the lower edge of the upper horizontal rail 2 to such an extent that the shield 6 can be rotated. Further, the upper end of the shield 6 is locked by the locking edge 21 at the right position in the drawing, and the engaged groove 7 on the left is engaged with the engaging edge 31, so that the shield 6 is just Thus, the shield 6 is easily self-supported by being sandwiched from the left and right by the engagement edge 31 and the engagement edge 31.

Next, the cross section L
The fence frame 1 and the shield 6 are connected and fixed at the upper and left and right positions by screws 9 via the letter-shaped bracket 8.
At this time, the bracket 8 having an L-shaped cross section does not need to be provided above and at the left and right positions of the shield 6 as in the embodiment, but may be provided at least at the upper position. Although the present embodiment has been described with respect to an example in which the present invention is applied to a blindfold of a two-stage garage, it is needless to say that the present invention can be applied to a fence erected on an adjacent boundary line. Further, in the present embodiment, two downwardly engaged grooves 7 of the shield 6 are arranged side by side so as to be attachable to the fence frame 1 on any surface without paying attention to the front and back of the shield 6. It may be one. Further, the shield 6 may be formed by forming an aluminum mold into a rectangular shape as in the present embodiment, or may be formed by casting an aluminum material.

[0010]

[Effects of the Invention] As described above, in the present invention, since the shield is reinforced by the fence frame, the strength of the fence itself is dramatically improved, and a highly durable fence is provided. Can be. In addition, the work of attaching the shield can be performed in a state where the shield is supported by the fence frame, so that the workability can be improved. Further, the shield can be easily replaced by attaching and detaching a bracket having an L-shaped cross section.
