Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fence-like panel suitable for a fence or the like, and more particularly relates to a fence-like panel formed from a single plate material and excellent in air permeability, light shielding property, strength, appearance, and the like.
[0002]
[Problems to be solved by the invention]
A fence-like body used for a veranda fence or the like is excellent in appearance, strength, air permeability, blindfold, and the like, and is preferably manufactured at an appropriate cost. Conventionally, various fence-like bodies having different shapes, materials and structures have been proposed and put into practical use. The fence-like body 100 shown in FIG. 19 is an example, but as shown in FIG. 20, the opening 102 is punched out from a single plate material, and the gap 104 between the openings serving as a horizontal rail is bent into a U shape. It is in the shape. Since the fence-like body 100 of this example is formed from a single plate material and can be formed only by pressing without requiring welding or the like, there is a feature that the work is easy and can be manufactured at low cost. However, there are the following problems that are expected to be improved.
[0003]
That is, since the fence-like body 100 has a shape similar to a corrugated plate, it is easily bent in the vertical direction in FIG. Also, in the left-right direction, it is relatively difficult to bend because the opening 104 between the horizontal bars is U-shaped, but higher rigidity is required depending on the application. It is rare. On the other hand, as for the exterior, the front side where the horizontal rails appear to protrude like a bowl is good, but there is a problem on the back side where the horizontal rails appear to be recessed in a groove shape, such as a garden fence where the appearance from both sides is evaluated. Is difficult to use. Further, the opening 102 in this example is formed by punching. For this reason, the punched plate material portion is discarded, which is not preferable because it is contrary to resource saving and requires a disposal cost. It is desirable to devise a method that effectively uses the waste amount as much as possible. Moreover, when constructing a long fence or the like, the fence-like body 100 must be connected. However, since the fence-like body 100 does not have a seat to be connected, it is inconvenient to newly provide a connection seat. At the same time, the cost is rising.
[0004]
Therefore, the present inventor is excellent in bending strength, appearance, material utilization rate, connection workability, etc., and as a result of earnestly examining the fence-like panel formed from a single plate material, the inventor has reached the present invention. .
[0005]
[Means for Solving the Problems]
The gist of the fence-like panel according to the present invention is a flat panel formed of a single plate material and regularly provided with a large number of openings, and at least one side of each opening is a panel. It is formed by a surface intersecting with the surface, and the space between the openings is bent in a bowl shape over the entire width of the panel .
[0008]
Furthermore, in such a fence-like panel, a tubular portion is formed by a surface portion intersecting with the panel surface and a portion sandwiched between the openings.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the fence-like panel and the fence-like body according to the present invention will be described in detail based on the drawings.
[0011]
A fence-like panel 10 shown in FIG. 1 is an example of a particularly useful embodiment of the present invention, and is suitably used for a fence or the like. The plate-like fence-like panel 10 is configured in a lattice shape with a cylindrical horizontal beam 12 and a flat plate-like vertical beam 14 that traverse the entire width, and a large number of strip-shaped openings 16 are regularly arranged in the vertical and horizontal directions. It has been. The upper and lower sides 17 and 19 of the opening 16 are formed by surfaces 27 and 29 orthogonal to the surface 25 of the fence-like panel 10, and the left and right sides 21 and 23 are formed by cut ends. In the present invention, the side formed by the surface intersecting the panel surface is not the side delimited by the cut end, but is located in the middle of a plane, curved surface, or folded surface that intersects the panel surface at a certain angle. This means the side that is formed. In the conventional fence-like body 100 shown in FIG. 19, the upper side 106 and the lower side 108 of the opening 102 are formed by being cut by punching as shown in FIG. Therefore, it is not a side formed by the surfaces 110 and 112 bent into a U shape, but a side formed by the lines of these cut ends, and is not included in the side defined by the present invention.
[0012]
The fence-like panel 10 is formed from a single plate material. That is, as shown in FIG. 2, a large number of openings 20 are set in the plate material 18, and H-shaped punching is performed at each position. Next, as illustrated in FIG. 3A, the horizontal rail portion 26 is bent between the male mold 28 and the female mold 30 and pressed into a bowl shape, but at the same time, the flat mold 32 adjacent to the male mold 28 is used. And the flat die 34 adjacent to the female die 30, the intersection of the horizontal beam portion 26 and the vertical beam portion 24 is bent at a right angle along the A line. As a result, the U-shaped cut-out portion 22 protrudes to the back side of the panel, and as shown in FIG. 12 will be formed.
[0013]
As shown in FIG. 4, the fence-like panel 10 at this time is such that the horizontal rail 12 remains open in a U shape, and further, the horizontal rail 12 is formed into a cylindrical shape by narrowing and closing the notch 22. 1 can be used as the fence-like panel 10 shown in FIG.
[0014]
In this example, an H-shaped punched product 31 is generated by punching at the opening 20, but depending on the material and thickness of the plate 18, as shown in FIG. , 34 are punched only by cutting, and the punched product 31 has a strip shape. Further, as shown in FIG. 5 (b), it is possible to prevent the punched material from being generated by cutting all the H-shapes.
[0015]
FIG. 6 shows an example in which the fence-like panel 10 is used by being incorporated in a block cage. The fence-like panel 10 is supported by the pole 36 and is incorporated in a part of the block rod 38. As shown in FIG. 7, the fence-like panel 10 is erected by being fixed to a pole 36 by a connecting member 40, and a pipe-like handrail 42 is provided on the top.
[0016]
FIG. 8 is an example of a fence in which a fence-like body 44 is erected on the block 46. The fence-like body 44 is configured by horizontally connecting the fence-like panels 10, and each fence-like panel 10 is erected on a block 46 by a pole 36. The fence-like panels 10 are connected to each other by inserting a common connecting rod into the pipe-shaped handrail 42 or the tubular horizontal rail 12 of the fence-like panels 10 adjacent to each other.
[0017]
Since the fence-like panel 10 of this example is manufactured by H-type punching, the material loss to be discarded is greatly reduced as compared with the conventional strip-type punching. Further, since the cross rail 12 is a cylinder having an elliptical cross section over the entire width of the panel, the bending strength in the vertical and horizontal directions is remarkably improved. Moreover, since the crosspiece 26 is bent into a U-shaped bowl shape and the cut portion 22 is squeezed and rounded, it has an excellent appearance from both the front and back sides. In addition, since the horizontal rail 12 is elongated to the left and right, it is excellent in light shielding and blinding despite high air permeability.
[0018]
The horizontal beam 12 of the fence-like panel 10 illustrated in FIG. 1 has a substantially elliptical cross section with different lengths on the left and right with respect to the vertical beam 14. It is not limited to an example, A suitable shape is selected based on a use. For example, FIG. 9 shows an example of a substantially elliptical cross section that is symmetric about the vertical beam portion 24. In FIG. 9A, the upper and lower cut portions 22 have the same length, and the tips of the cut portions 22 are connected to each other. The abutting portion 48 to be abutted is located directly beside, and FIG. 5B is an example in which the upper notch portion 50 is longer than the lower notch portion 52 and the abutting portion 48 is shifted to the lower right.
[0019]
FIG. 10 shows other cross-sectional shape examples. (A) is a circle, FIG. (B) is a square, FIG. (C) is a home plate-shaped pentagon, FIG. (D) is a front side with a circular arc on the back side, and FIG. FIG. (F) shows an example of an octagon, and FIG. (G) shows an example of a quadrangle provided only on the front surface.
[0020]
In the fence-like panel 10 illustrated in FIG. 1, two U-shaped cut portions 22 are formed in the opening portion 20 by H-shaped punching, and the upper and lower sides of the opening portion 16 intersect with the panel surface. 27, 29. An example in which the lengths of the upper and lower cut portions 22 are different is shown in FIG. However, in the present invention, it is only necessary that at least one side of the opening 16 intersects the panel surface. For example, as shown in FIG. By punching with a mold, bending the horizontal beam portion 26 (not shown in the figure) into a bowl shape and squeezing and cutting the cut portion 22, the cylindrical horizontal beam 12 having a substantially elliptical cross section as shown in FIG. Can be formed. In this example, only the lower side of the opening 16 is formed by a surface 29 that intersects the panel surface. Also in the fence-like panel of this example, as with the fence-like panel 10 illustrated in FIG. 1, effects such as improvement in strength, appearance, light-shielding property and blinding, and reduction in material loss are useful.
[0021]
If the two opposite sides of the opening 16 are formed by a plane intersecting the panel surface, the notch 22 is shortened, so that the drawing process is facilitated and the strength of the horizontal rail 12 is further improved.
[0022]
In the example of the fence-like panel 10 described above, the cross rails 12 are all cylindrical. Since it is cylindrical, the improvement in strength is particularly remarkable, the appearance from both the front and back surfaces is excellent, and functions such as the ability to insert a connecting rod to connect the fence-like panels 10 are also obtained. However, the present invention is not limited to the horizontal rail 12 being cylindrical. For example, in the horizontal beam 12 shown in FIG. 12A, the horizontal beam portion 26 is bent in a bowl shape, but the notch 22 is projected only in a shelf shape on the back side and is not closed. According to the fence-like panel of this example, compared to the conventional fence-like body 100 illustrated in FIG. 19, the material loss is reduced, and the effect of improving the light shielding property, the blinding property, and the like can be obtained. In FIG. 5B, the cut portion 22 protruding like a shelf on the back side is rounded with the upper portion recessed so that the strength is improved and the connecting member and the like can be easily taken in and out of the horizontal rail 12. There is. Moreover, in the same figure (c), since the cut | notch part 22 which protrudes in shelf shape on the back side is made into two top and bottom, it is convenient to insert and fit a connection member from the back side in the meantime.
[0023]
If the horizontal beam portion 26 is bent in a bowl shape, the strength of the horizontal beam 12 is increased and the appearance is improved. The shape of the ridge is not limited to the U shape, and may be an arc, a triangle, or a square as shown in FIG. The saddle shape refers to a state in which protrusions having substantially the same cross section are provided long and continuously. FIG. 13A shows an example in which the horizontal beam portion 26 is bent into a low bowl shape, but the present invention is not limited to the horizontal beam portion 26 being bent into a bowl shape. FIG. 13B shows an example of the horizontal rail 12 in which the horizontal rail portion 26 is kept flat. The cylindrical horizontal crosspiece 12 of this example is formed by bending the U-shaped cut portion 22 shown in FIG. 2 along the bottom line A and narrowing the cut portion 22 to make it round. Even in the fence-like panel provided with the horizontal rail 12 of this example, it is clear that strength and appearance are improved and material loss is reduced.
[0024]
Usually, the bowl-shaped bending process described with reference to FIG. 3 is performed for each row of the horizontal beam portion 26 and the vertical beam portion 24. Since it is necessary to feed the portion that is pulled convexly into the U shape from both sides, it is often difficult to bend two or more rows simultaneously. However, when the plate material is excellent in malleability or the height of the ridge is low, two or more rows can be bent simultaneously. The fence-like panel 10 shown in FIG. 14 is an example in which thick horizontal bars 58 and thin horizontal bars 60 are alternately bent and formed at the same time.
[0025]
Similarly, the fence-like panel 10 shown in FIG. 15 is also an example of being manufactured by simultaneously forming the horizontal bars 62 and 64. In the fence-like panel 10 shown in FIG. 6A, the openings 16 are alternately arranged in a so-called staggered pattern. In the fence-like panel 10 shown in FIG. The rows are arranged alternately. If the horizontal bars 62 and 64 remain flat as shown in FIG. 13B, only the bending process of the cut portion 22 is performed, so that simultaneous processing of two or more rows is easy.
[0026]
In the fence-like panel 10 shown in FIG. 16A, both the horizontal beam 12 and the vertical beam 14 are cylindrical. As illustrated in FIG. 5B, the punched object 66 is punched out while leaving the trapezoidal cut portions 22 on the four sides of the square opening, and the four cut portions 22 are bent back along the folding line 54. Narrow down. As a result, the fence-like panel 10 is obtained in which both the horizontal beam 12 and the vertical beam 14 have a cylindrical shape as shown in FIG. In the fence-like panel 10 of this example, all four sides of the opening 16 are formed by surfaces that intersect the panel surface.
[0027]
Alternatively, the fence-like panel 10 in which the annular cylindrical portion is disposed can be manufactured. As illustrated in FIG. 17B, the cutouts 74 and 76 are punched out so that the cutouts 70 and 72 remain on both sides of the ring portion 68, and the cutouts 70 and 72 are backside along the folding line 54. By narrowing down to a round shape, the fence-like panel 10 in which the annular cylindrical portions 78 are arranged vertically and horizontally as shown in FIG. In the fence-like panel 10 of this example, the entire periphery of the opening 80 and the four sides of the opening 82 are formed by surfaces intersecting with the panel surface.
[0028]
The fence-like panel of the present invention is manufactured using a metal plate such as a steel plate or an aluminum plate, or a plastic plate such as polypropylene or polycarbonate. A metal plate is preferably used because it has excellent malleability, is easy to process, and has high strength. Further, the plastic plate is lightweight and can be processed into a complicated shape by heating and softening, so that it is preferably used depending on the application.
[0029]
The fence-like panel of the present invention is used for a veranda or a garden fence, as well as an air conditioner wind direction adjusting plate, a decorative building material panel, a shutter, a heat exchanger, a wiring duct, a conveyor, a building interior / exterior material, a light shielding material, a groove Widely used for lids, various reinforcing materials, etc. In addition to being used in the form of a flat plate, for example, as shown in FIG. 18, it can be wound around a pipe 84 or a column and used as a reinforcing material or a decorative material. The top and bottom of the fence-like panel 10 can be easily connected by inserting a connecting rod into the adjacent cylindrical portion 86.
[0030]
In addition, the fence-like panel of the present invention is used alone, connected and used as a long fence, etc., partly cut out and combined with other members, or separated from a cylindrical part and used as a pipe Or bent into a cylindrical or arc shape and used as a structural material such as a column, or used as a reinforcing member or a decorative member.
[0031]
The present invention is not limited to the above description, and within the scope not departing from the spirit thereof, knowledge of persons skilled in the art regarding the material and shape of the fence-like panel, the manufacturing method, the method of connecting and fixing the fence-like panel, etc. Based on the above, the present invention can be implemented in a mode with various improvements, corrections, and modifications.
[0032]
【The invention's effect】
According to the fence-like panel according to the present invention, it is formed from a single plate material and can be formed only by pressing without requiring welding or the like. Therefore, the work is easy and can be manufactured at low cost. Further, since at least one side of the opening is formed by a surface intersecting with the panel surface, the bending strength of the panel is improved due to the structure in which the opening is bent in an arc or a corner. Shading and blinding are improved. In addition, not all of the openings are punched out, but a part or all of them are left, so that material loss to be discarded is greatly reduced.
[0033]
In particular, if the two opposite sides of the opening are formed by a plane intersecting the panel surface, the cut portion is shortened, so that the drawing process is facilitated and the strength of the cross rail is further improved.
[0034]
Furthermore, if the space between the openings is bent like a bowl over the entire width of the panel to form a horizontal beam or a vertical beam, the strength of the panel is improved and a three-dimensional appearance is obtained.
[0035]
Furthermore, if a cylindrical horizontal beam or vertical beam is formed by the surface part forming at least one side of the opening and the part sandwiched between the openings, the strength is further improved because the tube is cylindrical, and the front and back sides are further improved. The appearance from both sides is improved, and there is an effect that the connecting bars can be connected to each other by inserting a connecting rod into the horizontal beam or the vertical beam.
[0036]
Further, according to the fence-like body according to the present invention, the fence-like panels are connected horizontally and can be used for a long fence or the like, and connected vertically or vertically and horizontally for various building materials. Moreover, it is set as the fence-shaped body which partly cut off the fence-shaped panel, and it can combine with another member and can comprise a product. Alternatively, it is a fence-like body bent into a cylindrical shape or an arc shape, and can be used as a pillar or a constituent member such as a bench.
