Description

[Technical field]

[0001] The present invention relates to a fence system and a method for manufacturing a fence system. [Background technology]

[0002] Figures 8 and 9 show examples of locations where walls or fences (hereinafter collectively referred to as fences) can be installed. Figure 8 shows an example in which a fence 3 is installed in a straight line with an entrance / exit 4 between a site 1 on which a house or other structure is built and a road 2, while Figure 9 shows an example in which a fence 3 is installed around the perimeter of a site 1 located on a corner at an intersection or the like.

[0003] For example, if the fence 3 has a structure that makes it impossible to see the other side of the fence 3 (the side of road 2 as seen from site 1, and the side of site 1 as seen from road 2), in the example of FIG. 8, the (driver of) car C on site 1 and the (drivers of) cars A and B traveling on road 2 cannot see each other because they are shielded from each other by the fence 3. This may result in a collision accident or the like when car C attempts to exit onto road 2 through entrance / exit 4. Similarly, in the example of FIG. 9, the (driver of) car A and the (driver of) car B are shielded from each other by the fence 3 and cannot see each other, which may result in a collision accident or the like when they meet.

[0004] Regarding the structure of the fence, for example, Cited Document 1 describes a louver fence in which "slats, both ends of which are supported by the left and right vertical frames, are arranged side by side with a gap inside a fence frame formed by left and right vertical frames and upper and lower horizontal frames, the left and right vertical frames of the fence frame have longitudinal grooves formed on the corresponding inner faces, the slats have support plates attached to both ends and are supported by the vertical frames by fitting these support plates into the grooves formed in the vertical frames, and the support plates have receiving grooves into which the slats fit, formed at a portion corresponding to the opening of the groove at an inclination angle of 0° to 45° so that the groove ends are separated by a gap from the upper and lower edges of the support plates."

[0005] [Patent Document 1] JP 2013-227753 A Summary of the Invention [Problem to be solved by the invention]

[0006] The louver fence described in the cited document 1 can provide privacy (the inside cannot be seen from the outside of the fence) and ventilation. Conventionally, most fence structures have been designed to provide privacy, ventilation, and lighting, and no consideration has been given to improving visibility on the other side of the fence, for example to prevent vehicle collisions.

[0007] The present invention has been made in consideration of the above circumstances, and has an object to provide a fence system that improves visibility on the other side of the fence. [Means for solving the problem]

[0008] The present application includes a number of means for solving at least part of the above problems, examples of which are as follows.

[0009] In order to solve the above-mentioned problems, a fence system according to one embodiment of the present invention comprises a first fence and a second fence installed in a straight line on either side of an entrance / exit, the first fence and the second fence having a plurality of louvers arranged at horizontal intervals, the first fence being installed on the left side as viewed from a first moving body traveling along the first fence in a direction approaching the entrance / exit, and the plurality of louvers of the first fence being arranged at an angle α with respect to the traveling direction of the first moving body, and the second fence being installed on the right side as viewed from a second moving body traveling along the second fence in a direction approaching the entrance / exit, and the plurality of louvers of the second fence being arranged at an angle α with respect to the traveling direction of the second moving body.

[0010] The angle α may have a setting tolerance of 45°±20%, 45°±50%, or 45°-80%.

[0011] Of the multiple louvers arranged on the same fence, which is the first fence or the second fence, the angle α of a first louver can be made equal to or smaller than the angle α of a second louver arranged closer to the entrance / exit than the first louver.

[0012] A fence system according to another aspect of the present invention comprises a third fence and a fourth fence which form an angle β at a bend point, the third fence and the fourth fence having a plurality of louvers arranged at horizontal intervals, the third fence being installed on the left side as viewed from a first moving body traveling along the third fence in a direction approaching the bend point, and the plurality of louvers of the third fence being arranged at an angle α with respect to the traveling direction of the first moving body, and the fourth fence being installed on the right side as viewed from a second moving body traveling along the fourth fence in a direction approaching the bend point, and the plurality of louvers of the fourth fence being arranged at an angle α with respect to the traveling direction of the second moving body, the angle α being determined by the following formula and having a setting tolerance range of ±20%. α=45°+(90°-β) / 2

[0013] The angle α of the louvers in the third fence and the angle α of the louvers in the fourth fence can have a setting tolerance range of ±20% relative to the other, and the sum of the one and the other can be 180°-β.

[0014] The angle β may be a right angle.

[0015] The angle β may be an acute angle.

[0016] The angle β may be an obtuse angle.

[0017] The multiple louvers are arranged at a horizontal interval X, and if the actual width of the louvers is Z and the apparent width of the louvers when viewed from the road side is Y, the interval X can be set to satisfy the following formula. Y <X Y = Z cosα

[0018] The multiple louvers are arranged at a horizontal interval X, and if the actual width of the louvers is Z and the apparent width of the louvers when viewed from the road side is Y, the interval X can be set to satisfy the following formula. 0.5Y <X<1.5Y Y = Z cosα

[0019] The multiple louvers are arranged at a horizontal interval X, and if the actual width of the louvers is Z and the apparent width of the louvers when viewed from the road side is Y, the interval X can be set to satisfy the following formula. Y≧X Y = Z cosα

[0020] A manufacturing method for a fence system according to yet another aspect of the present invention includes preparing a first fence and a second fence having a plurality of louvers arranged at intervals in the horizontal direction, installing the first fence and the second fence in a straight line on either side of an entrance / exit, installing the first fence on the left side as viewed from a first moving body traveling along the first fence in a direction approaching the entrance / exit, and installing the second fence on the right side as viewed from a second moving body traveling along the second fence in a direction approaching the entrance / exit, and adjusting an angle α at which the plurality of louvers of the first fence incline with respect to the traveling direction of the first moving body, or the angle α is fixed in advance, and adjusting the angle α at which the plurality of louvers of the second fence incline with respect to the traveling direction of the second moving body, or the angle α is fixed in advance.

[0021] A further aspect of the present invention relates to a method for manufacturing a fence system, which includes preparing a third fence and a fourth fence having a plurality of louvers arranged at intervals in the horizontal direction, installing the third fence and the fourth fence so that they form an angle β at a bend point, installing the third fence on the left side as viewed from a first moving body traveling along the third fence in a direction approaching the bend point, and installing the fourth fence on the right side as viewed from a second moving body traveling along the fourth fence in a direction approaching the bend point, and adjusting an angle α at which the plurality of louvers of the third fence are inclined with respect to the traveling direction of the first moving body, or the angle α is fixed in advance and the angle α is adjusted with the plurality of louvers of the fourth fence inclined with respect to the traveling direction of the second moving body, or the angle α is fixed in advance, and the angle α is determined by the following formula and has a setting tolerance range of ±20%. α=45°+(90°-β) / 2 Effect of the Invention

[0022] According to the present invention, visibility on the other side of a fence can be improved.

[0023] Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, a number of embodiments according to the present invention will be described with reference to the drawings. In all the drawings for describing each embodiment, the same components are generally given the same reference numerals, and the repeated description thereof will be omitted. In the following embodiments, the components (including element steps, etc.) are not necessarily essential, except when specifically stated otherwise or when it is clearly considered essential in principle. In addition, when it is said that "consists of A," "consists of A," "has A," or "includes A," it does not exclude other elements, except when it is specifically stated that it is only that element. Similarly, in the following embodiments, when referring to the shape, positional relationship, etc. of components, etc., it includes those that are substantially similar or similar to the shape, etc., except when it is specifically stated otherwise or when it is clearly considered not essential in principle.

[0026] <Regarding the fence system 10 according to the first embodiment of the present invention> 1 shows an example of installation of a fence system 10 according to a first embodiment of the present invention. The fence system 10 is installed in a straight line between a site 1 on which a house or the like is built and a road 2, and is divided into a fence 11L and a fence 11R by an entrance / exit 4 for entering and exiting the site 1 and the road 2.

[0027] Fence 11L is installed on the left side as viewed from a vehicle or the like traveling on road 2 in a direction approaching entrance / exit 4 along fence 11L. Fence 11L corresponds to the first fence of the present invention. Fence 11R is installed on the right side as viewed from a vehicle or the like traveling on road 2 in a direction approaching entrance / exit 4 along fence 11R. Fence 11R corresponds to the second fence of the present invention.

[0028] For example, in the case of FIG. 1, the fence 11L is installed on the left side as seen from a car A (corresponding to a first moving body of the present invention) traveling on the road 2 in a direction approaching the entrance / exit 4 from the left side of the drawing (to the right of the drawing), and the fence 11R is installed on the right side as seen from a car B (corresponding to a second moving body of the present invention) traveling on the road 2 in a direction approaching the entrance / exit 4 from the right side of the drawing (to the left of the drawing). Hereinafter, when it is not necessary to distinguish between the fences 11L and 11R, they will be referred to as fences 11. The fence 11L has louvers 15 arranged at an angle α with respect to the traveling direction of the car A. Similarly, the fence 11R has louvers 15 arranged at an angle α with respect to the traveling direction of the car B.

[0029] 2 shows an example of the configuration of fence 11L. Fence 11L has a base portion 12, a support portion 13, an upper side portion 14, and a plurality of louvers 15. Fence 11R is configured in a similar manner and is symmetrical to fence 11L, so is not shown in the figure.

[0030] The base 12 is made of, for example, concrete, blocks, wood, metal, etc., and is formed into a wall shape having a height of, for example, about 1 m from the ground and is fixed to the ground. The support 13 is made of, for example, the same material as the base 12 and is fixed perpendicularly to the base 12. The upper side 14 forms the upper side of the fence 11L, and is fixed to the base 12 via the support 13 with a gap between it and the base 12 for arranging the louvers 15.

[0031] The louvers 15 are formed in the shape of a vertically long plate, for example, from metals such as aluminum and stainless steel, wood, plastic, etc. The multiple louvers 15 are inclined at the same angle α, and are spaced apart horizontally by X, with their lower ends fixed to the base 12 and their upper ends fixed to the upper side 14.

[0032] The same angle α and interval X of the multiple louvers 15 may not be fixed to the base 12, but may be variable so that, for example, an installer of the fence system 10 can change them according to the situation. Rotation of the louvers 15 (changing the angle α) can be realized, for example, by a mechanical structure in which the louvers 15 are fixed to a vertical rotation axis supported between the base 12 and the upper side 14. The louvers 15 may be rotatably supported on a vertical fixed axis supported between the base 12 and the upper side 14. The horizontal position of the louvers 15 (changing the interval X) can be realized, for example, by a mechanical structure in which mounting portions at both ends of the louvers 15 are movably supported on guide grooves or guide rails horizontally provided on the base 12 and the upper side 14, respectively.

[0033] Also, instead of setting the fence 11L directly on the ground, the fence 11L may be additionally set on top of a wall of concrete or other fence that has already been laid. In this case, as one example, the base part 12 (lower side part) and the upper side part 14 are made of a relatively light material such as metal, resin, or wood, and are configured to hold a plurality of louvers 15 as a frame with a diameter of about 5 to 20 cm.

[0034] If the support portion 13 is arranged on the side farther from the entrance 4, the visibility near the entrance 4 is improved. In addition, the support portion 13 is not limited to one, and multiple support portions 13 may be provided. For example, the support portions 13 may be provided at both ends or at the middle of the fence 11L to improve the strength of the fence 11L. Furthermore, the support portions 13 may be provided at the middle of the fence 11L, not at the ends. Alternatively, the support portion 13 may be omitted, and the base portion 12 (lower side portion) and the upper side portion 14 may hold the multiple louvers 15. Depending on the installation environment, at least one of the base portion 12 (lower side portion) and the upper side portion 14 may be omitted. When the base portion 12 is omitted, the multiple louvers 15 are installed on a wall made of concrete or the like that has been laid in advance, or on another fence.

[0035] Returning to FIG. 1, the angle α of each louver 15 of the fence 11 can be set to, for example, 45°. In this case, a car A traveling to the right in the drawing can see into the site 1 on the left front side through the gaps in the louvers 15 of the fence 11L, and can, for example, see a car C about to exit onto the road 2 from the entrance / exit 4. Similarly, a car B traveling to the left in the drawing can see into the site 1 on the right front side through the gaps in the louvers 15 of the fence 11R, and can, for example, see a car C about to exit onto the road 2 from the entrance / exit 4. The angle α may be set to a set tolerance range of, for example, 45°±20%, 45°±50%, or 45°-80% depending on the environment.

[0036] FIG. 3 is a diagram for explaining the interval X between adjacent louvers 15, and shows a horizontal cross section of louvers 15. As shown in FIG.

[0037] The louvers 15 of fence 11L installed on the left side of vehicle A traveling to the right in the drawing are inclined at angle α with respect to the traveling direction of vehicle A, and adjacent louvers 15 are installed with a distance X between them. Similarly, the louvers 15 of fence 11R installed on the right side of vehicle B traveling to the left in the drawing are inclined at angle α with respect to the traveling direction of vehicle B, and adjacent louvers 15 are installed with a distance X between them (not shown).

[0038] Here, when the lateral width of the louver 15 as viewed from the two sides of the road 2 in a direction orthogonal to the traveling direction of the vehicle is Y, and the actual lateral width of the louver 15 is Z, Y = Z·cosα.

[0039] And, as shown in the upper part of FIG. 3, if the louver 15 is installed such that Y < X, for example, when a pedestrian or the like looks straight in the direction of the fence 11 (the upward direction in the drawing) from the two sides of the road 2, the inside of the site 1 can be seen. Also, as shown in the lower part of FIG. 3, if the louver 15 is installed such that Y ≥ X, for example, when a pedestrian or the like looks straight in the direction of the fence 11 (the upward direction in the drawing) from the two sides of the road 2, the inside of the site 1 cannot be seen.

[0040] Therefore, when it is not necessary to consider hiding the site 1 when a pedestrian or the like looks straight in the direction of the fence 11 (the upward direction in the drawing) from the two sides of the road 2, the louver 15 may be installed such that Y < X. Specifically, for example, if 0.5Y < X < 1.5Y, the interval X between adjacent louvers 15 will not be too wide.

[0041] Conversely, when it is necessary to consider hiding the site 1 when a pedestrian or the like looks straight in the direction of the fence 11 (the upward direction in the drawing) from the two sides of the road 2, the louver 15 may be installed such that Y ≥ X.

[0042] As described above, according to the present embodiment, from vehicles A, B, etc. traveling on the road 2 in the direction approaching the entrance / exit 4, vehicles C, etc. within the site 1 trying to exit from the entrance / exit 4 to the road 2 can be visually recognized, so it is possible to expect prevention of head-on collision accidents and the like near the entrance / exit 4. Also, if the louver 15 is installed such that Y ≥ X, the line of sight when a pedestrian or the like looks straight in the direction of the fence 11 (the upward direction in the drawing) from the two sides of the road 2 can be blocked.

[0043] Note that the interval X and the apparent width Y of the louver 15 may be set to be different for each fence 11, or may be set to be partially different within the same fence 11 (for example, different between the half closer to the entrance / exit 4 and the half farther away).

[0044] <Modification of the first embodiment> FIG. 4 shows a modified example of the first embodiment. In the first embodiment (FIG. 1), the angles α of the multiple louvers 15 constituting the fence 11 are the same. In this modified example, the angles α of the multiple louvers 15 constituting the fence 11 are not the same, but are set so that the angle α of the louvers 15 closer to the entrance 4 is 45° and the angle of the louvers 15 farther from the entrance 4 is smaller than 45°, for example, in the range of 0°<α≦45°. Specifically, the angle α may be gradually decreased, for example, 45°, 40°, 35°, . . . , 5°, etc., as it becomes farther from the entrance 4. In addition, for example, the angle α of the louvers 15 may be divided into multiple stages (for example, two stages of 45° and 30°), and the angle α of the multiple louvers 15 closer to the entrance 4 may be set at 45°, and the angle α of the multiple louvers 15 farther from the entrance 4 may be set at 30°.

[0045] According to this modified example, compared to the first embodiment, cars A, B, etc. traveling at a position farther away from the entrance / exit 4 can see cars C, etc. within the site 1 that are about to exit onto the road 2 from the entrance / exit 4.

[0046] <Regarding the fence system 20 according to the second embodiment of the present invention> 5 shows an example of installation of a fence system 20 according to a second embodiment of the present invention. The fence system 20 includes a fence 21L and a fence 21R, and is arranged, for example, along a corner lot 1 such that the fences 21L and 21R form an angle β of 90° at a bending point 22. The fence 21L corresponds to the third fence of the present invention, and the fence 21R corresponds to the fourth fence of the present invention.

[0047] Fence 21L is installed on the left side as viewed from a vehicle or the like traveling on road 2 in a direction approaching bend point 22 along fence 21L. Fence 21R is installed on the right side as viewed from a vehicle or the like traveling on road 2 in a direction approaching bend point 22 along fence 21R.

[0048] For example, in the case of FIG. 5, the fence 21L is installed on the left side as viewed from a car A traveling on the road 2 in a direction approaching the bending point 22 from the left side of the drawing (to the right of the drawing), and the fence 21R is installed on the right side as viewed from a car B traveling on the road 2 in a direction approaching the bending point 22 from the top of the drawing (to the bottom of the drawing). Hereinafter, when it is not necessary to distinguish between the fences 21L and 21R, they will be referred to as fences 21. The fence 21L has a louver 15 inclined at an angle α with respect to the traveling direction of the car A. Similarly, the fence 21R has a louver 15 inclined at an angle α with respect to the traveling direction of the car B. The angle α can be, for example, 45°. Note that the angle α may have a setting tolerance range of 45°±10% or 45°±20% depending on the environment. The angle α of the fence 21L and the angle α of the fence 21R may not be the same but may be different. In this case, it is preferable that one of the angles has a setting tolerance of ±20% with respect to the other, and that the sum of the one angle and the other angle is set to 90°.

[0049] The structure, apparent width Y, and spacing X of fence 21 are similar to those of fence 11 (FIG. 2), and therefore will not be described here.

[0050] According to this embodiment, cars A and B traveling on road 2 in a direction approaching bending point 22 can see each other, which is expected to prevent accidents such as collisions when meeting near bending point 22. In addition, by installing louvers 15 so that Y≧X, it is possible to block the line of sight of pedestrians, etc., looking straight toward fence 21 from the road 2 side.

[0051] <Fence system 30 according to the third embodiment of the present invention> 6 shows an example of installation of a fence system 30 according to a third embodiment of the present invention. The fence system 30 includes a fence 31L and a fence 31R, and for example, the fences 31L and 31R are arranged along a corner lot 1 so that they form an acute angle β at a bending point 32. The fence 31L corresponds to the third fence of the present invention, and the fence 31R corresponds to the fourth fence of the present invention.

[0052] Fence 31L is installed on the left side as viewed from a vehicle or the like traveling on road 2 in a direction approaching bend point 32 along fence 31L. Fence 31R is installed on the right side as viewed from a vehicle or the like traveling on road 2 in a direction approaching bend point 32 along fence 31R.

[0053] For example, in the case of Fig. 6, the fence 31L is installed on the left side as seen by car A traveling on road 2 in a direction approaching refraction point 32 from the left side of the drawing (to the right in the drawing), and the fence 31R is installed on the right side as seen by car B traveling on road 2 in a direction approaching refraction point 32 from the top of the drawing (to the lower right in the drawing). Hereinafter, when there is no need to distinguish between fences 31L and 31R, they will be referred to as fence 31. Fence 31L has louvers 15 inclined at an angle α with respect to the traveling direction of car A. Similarly, fence 31R has louvers 15 inclined at an angle α with respect to the traveling direction of car B.

[0054] In this embodiment, the angle α is defined as in the following equation (1). α = 45° + (90° - β) / 2 (1)

[0055] For example, when the acute angle β is 60°, the angle α=45°+(90°-60°) / 2=60°. The angle α calculated by formula (1) may have a setting tolerance of ±10% or ±20% depending on the environment. The angle α of the fence 31L and the angle α of the fence 31R may not be the same but may be different. In that case, it is preferable to set one of them so that it has a setting tolerance of ±20% with respect to the other, and to set the sum of the one and the other to be 180°-β.

[0056] It should be noted that formula (1) can also be applied to the angle α in the second embodiment described above. In that case, since the fences 21L and 21R in the second embodiment are perpendicular to each other, the angle β can be substituted into formula (1) as 90°. The angle α of the louver 15 in the second embodiment is calculated as 45° (=45°+(90°-90°) / 2).

[0057] The structure, apparent width Y, and spacing X of the fence 31 are similar to those of the fence 11 (FIG. 2), and therefore will not be described here.

[0058] According to this embodiment, cars A and B traveling on road 2 in a direction approaching bending point 32 can see each other, which is expected to prevent accidents such as collisions when meeting near bending point 32. Furthermore, by installing louvers 15 so that Y≧X, it is possible to block the line of sight of pedestrians, etc., looking straight toward fence 31 from the road 2 side.

[0059] <Fence system 40 according to the fourth embodiment of the present invention> 7 shows an example of installation of a fence system 40 according to a fourth embodiment of the present invention. The fence system 40 includes a fence 41L and a fence 41R, and for example, the fences 41L and 41R are arranged along a corner lot 1 so that they form an obtuse angle β at a bending point 42. The fence 41L corresponds to the third fence of the present invention, and the fence 41R corresponds to the fourth fence of the present invention.

[0060] Fence 41L is installed on the left side as viewed from a vehicle or the like traveling on road 2 in a direction approaching bend point 42 along fence 41L. Fence 41R is installed on the right side as viewed from a vehicle or the like traveling on road 2 in a direction approaching bend point 42 along fence 41R.

[0061] For example, in the case of FIG. 7, the fence 41L is installed on the left side as seen by a car A traveling on the road 2 in a direction approaching the bending point 42 from the left side of the drawing (to the right in the drawing), and the fence 41R is installed on the right side as seen by a car B traveling on the road 2 in a direction approaching the bending point 42 from the top of the drawing (to the lower left in the drawing). Hereinafter, when it is not necessary to distinguish between the fences 41L and 41R, they will be referred to as fence 41. The fence 41L has louvers 15 inclined at an angle α with respect to the traveling direction of the car A. Similarly, the fence 41R has louvers 15 inclined at an angle α with respect to the traveling direction of the car B.

[0062] In this embodiment, the angle α can be calculated using formula (1). For example, when the obtuse angle β is 120°, the angle α is calculated as 45°+(90°-120°) / 2=30°. The angle α calculated by formula (1) may have a setting tolerance of ±10% or ±20% depending on the environment. The angle α of the fence 41L and the angle α of the fence 41R may not be the same but may be different. In that case, it is preferable to set one of them so that the other has a setting tolerance of ±20% and the sum of the one and the other is 180°-β.

[0063] The structure, apparent width Y, and spacing X of the fence 41 are similar to those of the fence 11 (FIG. 2), and therefore will not be described here.

[0064] According to this embodiment, cars A and B traveling on road 2 in a direction approaching bending point 42 can see each other, which is expected to prevent accidents such as collisions when meeting near bending point 42. Furthermore, by installing louvers 15 so that Y≧X, it is possible to block the line of sight of pedestrians, etc., looking straight toward fence 41 from the road 2 side.

[0065] The present invention is not limited to the above-described embodiment and modifications, and various modifications are possible. For example, the above-described embodiment and modifications have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those having all of the configurations described. In addition, it is possible to replace a part of a modification with another modification, or to combine the modifications.

[0066] The fence system according to each embodiment can be installed not only between the site 1 and the road 2, but also between two areas (spaces) separated by a fence.
