Abstract

<P>PROBLEM TO BE SOLVED: To surely prevent the breakdown of a fence by expanding or contracting a panel while following to the change of the place of a support or turning the fence around the support even when the place of the support is changed by the variation of an earth crust by an earthquake. <P>SOLUTION: The fence has a pair of the supports 2 and 5, one panel 1 rotatably fitted to one support 2 by hinges 3 and the other panel 4 rotatably fitted to the other support 5 by the hinges 6 and partially superposed to one panel 1. The fence further has a supporting means slidably supporting horizontally the other panel 4 to one panel 1. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  This invention relates to a fence, in particular, a fence in which a panel is attached between columns, even if the position of the column changes due to a change in the crust due to an earthquake, the panel is expanded or contracted according to the change or centered on the column. The present invention relates to a fence that can reliably prevent the destruction of the fence by making it turnable.

  When the earth's crust fluctuates due to an earthquake, the position of fence posts built on the ground changes. That is, the distance between the columns changes, or the position does not change but the position changes. When the position of the column changes in this way, the fence panel fixed between the columns is damaged. If the panel breaks, the function as a fence is lost, so the fence must be repaired and rebuilt, which requires enormous time and money.

  As a means for solving such a problem, it can be considered that a bolt insertion hole for fixing the fence panel to the support column is formed in a long hole to absorb the change in the distance between the support columns.

  However, there is a limit to absorbing the change in the position of the column by forming the bolt insertion hole into a long hole, and it is impossible to follow the large fluctuations that occur during an earthquake.

  Therefore, in order to be able to follow even if the position of the pillar changes greatly due to an earthquake or the like, the fence panel between the pillars can be expanded or contracted or swiveled around the pillar, but the fence is still Not proposed.

  Therefore, even if the position of the column changes due to the change in the crust due to the earthquake, the object of the present invention is to prevent the destruction of the fence by making the panel extend or retract or pivot around the column following the change. It is to provide a fence that can be.

  The present invention has been made to achieve the above object, and is characterized by the following.

  The invention according to claim 1 is a pair of struts, one panel pivotally attached to one of the pair of struts, and the one panel pivotally attached to the other of the pair of struts; The present invention is characterized in that it is provided with another panel that is partially overlapped, and support means that slidably supports the other panel in the horizontal direction with respect to the one panel.

  The invention according to claim 2 is the invention according to claim 1, wherein the support means includes a guide rail attached to one panel and a guide pin attached to the other panel and moving along the guide rail. It has the feature in being.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein one of the panels and the other panel is a mesh panel which is attached to the trunk edge and is formed by assembling vertical bars and horizontal bars in a lattice shape. It has the feature in being.

  According to the present invention, even if the position of the column changes due to the change in the crust due to the earthquake, the panel follows the change, and the panel rotates or pivots around the column, so that it is possible to reliably prevent the destruction of the fence. The

  An embodiment of the fence of the present invention will be described with reference to the drawings.

  1 is a front view showing a fence according to the present invention, FIG. 2 is a plan view showing the fence according to the present invention, FIG. 3 is a cross-sectional view taken along the line BB of FIG. 1, and FIG. FIG. 5 is a plan view showing a state in which the fence panel is turned.

  1 to 5, 1 is one panel that is pivotally attached to one strut 2 of a pair of struts by a hinge 3, and 4 is pivotable by a hinge 6 to the other strut 5 of the pair of struts. The other panel is attached, and one panel 1 and the other panel 4 are partially overlapped. Reference numerals 7A and 7B denote upper and lower support means for slidably supporting the other panel 4 in the horizontal direction with respect to the one panel 1.

  One and the other panels 1 and 4 are mesh panels in which vertical bars 9 and horizontal bars 10 are assembled in a lattice shape and are attached to left and right vertical trunk edges 8A and upper and lower horizontal trunk edges 8B. Of course, the panels 1 and 4 may be other than the mesh panel. The upper ends of the vertical trunk edges 8A of the panels 1 and 4 extend upward, and a barbed wire 11 is stretched between the upper ends. The upper part of the support | pillars 2 and 5 is curving in the shape of a unilateral.

  The upper support means 7A includes two guide rails 12 horizontally attached to the upper part between the left and right vertical trunk edges 8A of one panel 1, and two pieces attached to the upper horizontal trunk edge 8B of the other panel 4. And a guide pin 14 attached to a bracket 13 that freely slides between the guide rails 12. The lower support means 7B has the same configuration as the upper support means 7A. That is, two guide rails 12 attached horizontally to the lower part between the left and right vertical trunk edges 8A of one panel 1 and two guide rails 12 attached to the lower horizontal trunk edge 8B of the other panel 4. And a guide pin 14 attached to the bracket 13 that slides freely along the gap.

  According to the fence of the present invention configured as described above, even if the distance between one strut 2 and the other strut 5 is widened due to an earthquake as shown by a one-dot chain line in FIG. One panel 1 and the other panel 4 are smoothly slid and extended in the horizontal direction by the supporting means 7A and 7B, so that the fence is not damaged. Similarly, when the distance between the columns 1 and 5 is narrowed, the panel slides smoothly and contracts, so that the fence is not damaged.

  Further, as shown by a one-dot chain line in FIG. 5, even if the position of the other support column 5 is changed with respect to one support column 2 due to an earthquake, the one panel 1 and the other panel 4 are hinged 3. , 6 are attached to the columns 2, 5 so that the panels 1, 4 pivot around the hinges 3, 6 so that the fence is not damaged.

  In addition, even if the expansion / contraction and turning of the panel described above occur at the same time, the fence can be followed, so that the fence is not damaged.

It is a front view which shows the fence of this invention. It is a top view which shows the fence of this invention. It is the BB sectional view taken on the line of FIG. It is the A section enlarged view enclosed with the dashed-dotted line of FIG. It is a top view which shows the state which the panel for fences turned.
