Multiple horizontal bars may sway due to wind, etc., and there is a risk that the fence may rattle due to the shaking of the horizontal bars. Therefore, it is preferable that the frame member supporting the horizontal beam be firmly fixed.

One of the objects of the present disclosure is to provide a technique for suppressing rattling of a vertical frame that supports a small crosspiece.

In order to solve the above problems, a fence according to an aspect of the present invention includes a pair of vertical frames, a plurality of small bars that extend in the horizontal direction and have both ends supported by the pair of vertical frames, and a fence that extends in the horizontal direction. It includes a pair of upper and lower frames that extend and are arranged above and below the plurality of small bars, and a pair of vertical bars that cover the pair of vertical frames. At least one of the upper and lower frames is screwed to a pair of vertical frames.

It is a front view of the fence of an Example. It is a front view of the 1st subassembly which consists of a vertical frame and a small crosspiece. FIG. 3 is an enlarged top view of the first subassembly. FIG. 2 is a sectional view taken along line AA of the fence shown in FIG. 1. FIG. It is a top view of a vertical beam. FIG. 2 is a sectional view taken along line BB of the fence shown in FIG. 1. FIG. It is a figure for demonstrating the joining process of a vertical frame and an upper and lower frame.

FIG. 1 is a front view of a fence 10 according to an embodiment. The fence 10 includes a post 20, an upper bracket 22a, a lower bracket 22b (referred to as "bracket 22" if these are not distinguished), an upper rail 24a, a lower rail 24b (referred to as "upper and lower rails 24" if these are not distinguished), and a vertical rail. 26, small crosspieces 28, upper and lower frames (not shown), and vertical frames (not shown).

The fence 10 is of a so-called free pole type, and the main body 12 is made up of an upper crosspiece 24a, a lower crosspiece 24b, a vertical crosspiece 26, a small crosspiece 28, an upper and lower frame (not shown), and a vertical frame (not shown). 20 and a bracket 22.

The post 20 is erected on the ground or the like and supports the main body 12 of the fence 10. Brackets 22 connect body portion 12 of fence 10 to posts 20. The upper bracket 22a is fixed to the upper end of the main body 12, and the lower bracket 22b is fixed to the lower end of the main body 12.

The upper and lower crosspieces 24 are located at the upper and lower ends of the main body 12 and extend in the lateral direction (horizontal direction). The upper and lower crosspieces 24 are connected to upper and lower frames (not shown) and cover the upper and lower frames.

The vertical bars 26 are located at the left and right ends of the main body portion 12 and extend in the longitudinal direction (vertical direction). The vertical beam 26 is connected to a vertical frame (not shown) and covers the vertical frame. Note that the direction perpendicular to the horizontal direction and the vertical direction is referred to as the perpendicular direction. The perpendicular direction is perpendicular to the surface of the main body portion 12 .

A plurality of small bars 28 are provided in parallel and extend in the horizontal direction. The small bar 28 may have a cylindrical shape with a rectangular cross section. Both ends of the small crosspiece 28 are fixed to a pair of vertical frames. The small crosspiece 28 may be formed into a wall shape or a column shape.

FIG. 2 is a front view of the first subassembly 14 consisting of the vertical frame 32 and the small crosspiece 28. Both ends of the plurality of small bars 28 are supported by a pair of vertical frames 32. The connecting portion 34 that connects the end of the small crosspiece 28 and the vertical frame 32 may be configured by caulking, for example, or may be configured by screwing. By joining the small crosspiece 28 and the vertical frame 32 by caulking, screws for screwing can be eliminated, and the joining part 34 can be simplified. The method of caulking the joint portion 34 may be clinch caulking. A rectangular first subassembly 14 is formed by combining the plurality of small bars 28 and the pair of vertical frames 32.

FIG. 3 is an enlarged top view of the first subassembly 14. The small crosspiece 28 and the vertical frame 32 are connected by a connecting portion 34. The vertical frame 32 has a threaded portion 32a, an extension portion 32b, a flange portion 32c, a coupling plate portion 32d, and a cover portion 32e.

The threaded portion 32a is formed into a substantially semi-cylindrical shape, is open in the vertical direction, and functions as a screw hole into which a screw can be screwed. The threaded portion 32a can receive screws in the vertical direction. The threaded portion 32a is formed for screwing the vertical frame 32 to the upper and lower frames.

The extending portion 32b extends from the threaded portion 32a in a direction perpendicular to the surface in order to suppress movement of the vertical frame 32 in the direction perpendicular to the surface during assembly. The flange portion 32c is formed by bending the end of the extending portion 32b. The flange portion 32c engages with the vertical bar 26 to restrict movement of the vertical bar 26 in the lateral direction.

The coupling plate portion 32d extends laterally from the outer circumferential surface of the threaded portion 32a, and makes surface contact with the end portion of the small crosspiece 28. With the connecting plate portion 32d and the small crosspiece 28 in surface contact, the connecting plate portion 32d and the end of the small crosspiece 28 are combined by caulking.

The cover portion 32e is bent from the end of the coupling plate portion 32d in a direction away from the small crosspiece 28. The cover portion 32e is formed to cover the connecting portion 34 between the connecting plate portion 32d and the small crosspiece 28.

FIG. 4 is a cross-sectional view of the fence 10 taken along line AA shown in FIG. Note that although a screw is shown inserted into the threaded portion 32a, the upper and lower frames fastened with the screw are not shown in FIG. Moreover, FIG. 5 is a top view of the vertical beam 26. The vertical frame 32 is slidably fitted to the vertical frame 26. A second subassembly is formed by assembling the small bars 28, the vertical frames 32, and the vertical bars 26.

As shown in FIG. 5, the vertical beam 26 has a facing plate portion 26a, a connecting plate portion 26b, a regulating protrusion 26c, a receiving portion 26d, and a protruding portion 26e. The pair of opposing plate portions 26a are provided in parallel and face each other in a direction perpendicular to the plane. The connecting plate portion 26b connects the pair of opposing plate portions 26a. The connecting plate portion 26b has a recess that can be engaged with the threaded portion 32a of the vertical frame 32.

The pair of regulating protrusions 26c respectively protrude from the pair of opposing plate parts 26a and are positioned laterally offset from the connecting plate part 26b. The receiving portion 26d is formed in a bifurcated shape at the end of one of the pair of opposing plate portions 26a. The protruding portion 26e is formed to protrude from the end of the other opposing plate portion 26a. The receiving portion 26d and the protruding portion 26e extend in the vertical direction, and the protruding portion 26e can be engaged by entering the receiving portion 26d.

As shown in FIG. 4, the flange portion 32c of the vertical frame 32 fits between the connecting plate portion 26b and the regulating protrusion 26c, thereby restricting the movement of the vertical frame 32 in the lateral direction. The extending portion 32b of the vertical frame 32 comes into contact with the opposing plate portion 26a of the vertical frame 26, thereby restricting the movement of the vertical frame 32 in the direction perpendicular to the surface. When assembling the vertical beam 26 and the vertical frame 32, the vertical beam 26 is assembled by fitting the flange portion 32c between the connecting plate portion 26b and the regulating protrusion 26c and sliding it in the vertical direction. The connecting plate portion 26b and the regulating protrusion 26c function as a slide guide for sliding the vertical frame 32. Since the pair of vertical bars 26 and the pair of vertical frames 32 can be connected by sliding in the vertical direction, the work is easy.

The cover portion 32e covers the joint portion 34 between the small crosspiece 28 and the joint plate portion 32d of the vertical frame 32 together with the opposing plate portion 26a of the vertical frame 26. This can prevent the joint portion 34 from being exposed and coming into contact with people.

FIG. 4 shows a state in which the vertical bars 26 are connected to each other. The receiving part 26d of one vertical bar 26 engages with the protruding part 26e of the other vertical bar 26, and the protruding part 26e of one vertical bar 26 engages with the receiving part 26d of the other vertical bar 26. Thereby, the lateral length can be freely set by connecting the plurality of second subassemblies.

The slit portion of the threaded portion 32a of the vertical frame 32 fits into the recess of the connecting plate portion 26b. Thereby, it is possible to suppress rotation of the vertical frame 32 with respect to the vertical frame 26 when tightening the screws.

FIG. 6 is a cross-sectional view of the fence 10 taken along line BB shown in FIG. A second subassembly consisting of the vertical bars 26, vertical frames 32, and small bars 28 is screwed to the upper and lower frames 30 to constitute a third subassembly. The pair of upper and lower frames 30 is formed into a flat plate shape, extends in the horizontal direction, and is arranged above and below the plurality of small bars 28, respectively. The pair of upper and lower frames 30 are connected to the pair of vertical frames 32 by being screwed in the vertical direction. Here, the combination of the vertical frame 32 and the upper and lower frames 30 will be explained with reference to FIG.

FIG. 7 is a diagram for explaining a process of joining the vertical frame 32 and the upper and lower frames 30. FIG. 7(a) shows a state in which the upper frame 30a is placed on the vertical frame 32 before the screws are tightened, and FIG. 7(b) shows a state after the screws 36 are tightened. Note that the lower end of the vertical frame 32 and the lower frame 30b are first screwed together.

Since the vertical length of the vertical frame 26 is shorter than that of the vertical frame 32, it does not contact the upper frame 30a before the screws 36 are tightened. In addition, in FIG. 7A, the length in the vertical direction of the vertical frame 26 and the length in the vertical direction of the vertical frame 32 are shown to be much different from each other than they actually are.

The screw 36 is inserted into the insertion hole 38 of the upper frame 30a and tightened to the threaded portion 32a. When the screws 36 are tightened, the vertical frame 32 is moved toward the upper frame 30a, and the upper end of the vertical frame 26 is pressed against the upper frame 30a, as shown in FIG. 7(b). Since the vertical frame 26 is shorter than the vertical frame 32, it does not interfere with the initial stage of screw tightening between the vertical frame 32 and the upper frame 30a, and comes into contact with the upper frame 30a when the screws are tightened deeply. As a result, the vertical frame 32 and the upper frame 30a are firmly tightened, and the vertical frame 26 finally comes into contact with the upper frame 30a, thereby suppressing vertical wobbling of the vertical frame 26.

By directly screwing the vertical frame 32 to the upper and lower frames 30, rattling between the vertical frame 32 and the upper and lower frames 30 can be suppressed. Since the vertical frame 32 is directly fixed to the small crosspiece 28, it is integrated with the small crosspiece 28, and is very effective in suppressing the rattling of the vertical frame 32 when the small crosspiece 28 shakes due to the wind. It is true.

Return to FIG. 6. The upper crosspiece 24a and the lower crosspiece 24b have a substantially U-shaped cross section. A pair of rail grooves 40 are formed on the inner surfaces of the upper rail 24a and the lower rail 24b, respectively. The rail groove 40 is formed by a pair of ribs formed on the inner surface of the upper and lower crosspieces 24, and extends laterally. The pair of rail grooves 40 face each other, receive the side edges of the upper and lower frames 30, and grip the upper and lower frames 30 in a slidable manner. By sliding the pair of rail grooves 40 and the side edges of the upper and lower frames 30, the upper and lower crosspieces 24 and the upper and lower frames 30 are connected, and the main body 12 is assembled. As a result, a plurality of third assemblies are assembled into one main body portion 12. In addition, in the main body part 12, caps may be provided to cover both ends of the upper and lower bars 24, and a cover member may be provided to cover the outer surface of the vertical bars 26.

By screwing the upper and lower frames 30 and the vertical bars 26 in the vertical direction, it becomes possible to slide the side edges of the upper and lower frames 30 into the rail grooves 40, making assembly easy.

The main body portion 12 is connected to the support column 20 by a bracket 22. The upper bracket 22a is hooked on the lower surface of the upper crosspiece 24a, and restricts the downward movement of the upper crosspiece 24a and the movement of the upper crosspiece 24a away from the support 20. The lower bracket 22b comes into contact with the lower surface of the lower crosspiece 24b, and restricts the downward movement of the lower crosspiece 24b. The lower bracket 22b is screwed to the support column 20. In this way, the fence 10 is assembled with the main body 12 supported by the pillars 20. A worker can easily install the fence 10 by assembling the main body 12 in advance, transporting it to the work site, and connecting it to the posts 20.

The assembly process of the main body portion 12 will be explained.
(1) First step The small crosspiece 28 and the vertical frame 32 are joined by the joining part 34.
(2) Second step The vertical frame 32 is slidably fitted onto the vertical beam 26. In this state, the sliding of the vertical frame 32 and the vertical beam 26 is not restricted. Further, depending on the horizontal length of the fence 10, a step of connecting the vertical bars 26 may be added.
(3) Third step The vertical frame 32 is screwed to the upper and lower frames 30 in the vertical direction. The vertical bars 26 are pressed against the upper and lower frames 30 when screwed.
(4) Fourth step The upper and lower frames 30 are slidably fitted to the upper and lower crosspieces 24.
In this way, the main body portion 12 is assembled and attached to the pillars 20 to form the fence 10.
