Description

[Detailed description of the invention] [Industrial application field] This invention protects, for example, green belts on roads, green belts in parks, etc. from pedestrians crossing or stepping on them, and also protects the bushes from pedestrians crossing or stepping on them during snowfall in winter. The present invention relates to a protective fence that protects vehicles from snow loads.

[Conventional technology] Road green belts, park green belts, etc. are formed by planting rhododendrons and other trees and plants, and during the snowy season, these road green belts, park green belts, etc. are covered with snow. The load has caused damage to planted trees and plants, such as broken branches. For this reason, in the past, in these green areas, wooden poles were built near trees and plants, and from the wooden poles rope-like objects woven from wood, bamboo, and rope were placed over the trees and plants as snow fences. trees,
It protected the plants from the snow load.

[Problems to be solved by the invention] Green belts in snowy areas are often used in winter as dumping grounds for snow removed and collected from adjacent roads by snowplows and the like.
Conventional snow enclosures using wooden poles as described above do not have enough durability to support the accumulated load of accumulated snow and snow that has been removed and collected. However, there was a problem in that it required replanting and maintenance, which increased the cost of maintaining the green belt.

Additionally, during periods other than winter, there is a problem in that the shrubbery must be protected from pedestrians crossing or stepping on it, while at the same time allowing the shrubbery to be admired without spoiling its aesthetic appearance.

This idea was made to solve this problem, and even if snow accumulated by removing snow from sidewalks and roadways accumulates in the winter, it will protect the trees and trees in the green areas of roads and parks. To provide a protective fence that allows the user to view the shrubbery without spoiling its beauty during periods other than the winter season.

[Means for solving the problem] The protective fence according to this invention includes a plurality of substantially U-shaped frames arranged at predetermined intervals with the opening side facing downward, and a beam between the frames. is a protective fence installed across the frame, the beam comprising upper and lower beams installed between the rising parts of the frame, and a connecting beam that connects the upper and lower beams to each other; The beam is rotatably attached to the rising portion of the frame, and the lower beam is configured to be attachable to and detachable from either the rising portion or the horizontal portion of the frame.

[Function] The protective fence according to this invention can be used during the winter period (snowy period).
In this case, the lower beam is attached to the horizontal part of the frame. As a result, the lower beam and connecting beam will cover the green area together with the frame, so if you cover the upper and side sides with a sheet or mat, you can remove the snow collected by removing snow from sidewalks and roads. Even when dumped on top, the snow is retained on the beam and frame and on top of the frame.

On the other hand, during periods other than winter, the lower beam is attached to the rising part of the frame. As a result, the beams that cover the top of the green area are removed, allowing visitors to appreciate the shrubbery without compromising its aesthetic appearance, and it functions as a protective fence to prevent pedestrians from stepping on it.

[Example] Fig. 1 is an explanatory diagram showing a protective fence that is the premise of this invention. approximately U-shaped frames, 2 is a side beam installed between the rising parts 3 of these frames, 4 is
is a horizontal part beam installed between the horizontal parts 5 of the frame 1.

In the protective fence configured as described above, the frame 1 and the side and horizontal beams 2 and 4 cover the green area. Therefore, if the top and sides of the protective fence are covered with sheets or mats 6 as shown in Figure 2, the snow collected by removing snow from sidewalks and driveways can be dumped onto the green belt. Even in this case, the snow 7 is accumulated and retained on the frame 1 and the side and horizontal beams 2 and 4, as shown in Fig. 3, and the trees and plants 8 in the green belt are protected. Become. In addition, it functions as a pedestrian protection fence or an access protection fence as a normal protection fence except during the winter season.

The protective fence shown in Figure 1 reliably protects the green zone from the load of snow, but since it is a fixed structure throughout the year, the beams can cover the top of the green zone even during periods other than winter. This is not desirable from an aesthetic point of view.

Therefore, the present invention has a structure that allows the beam arrangement to be changed depending on the season. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 4 to 16.

In these figures, 1 to 3 and 5 are the same as those in FIG.
The frame 1 is made up of an upper beam 9 provided on the upper part of the rising part 3 of the frame 1, a lower beam 10 provided below the rising part 3 of the frame 1, and a connecting beam 11 connecting the upper beam 9 and the lower beam 10. The end of the upper beam 9 is rotatably attached to the frame 1, and the lower beam 10 is connected to the connecting beam 11.
The end of the bracket is configured so as to be attachable to and detachable from the rising portion 3 of the frame 1 and so as to be attachable to and detachable from the horizontal portion 5 of the frame 1 .

Reference numeral 12 denotes an upper mounting bracket for rotatably attaching the end of the upper beam 9 to the upper part of the rising portion 3 of the frame 1, and this upper mounting bracket has a U-shape as shown in FIGS. 8 and 9. shaped bracket 13
, bolts 14 and nuts 15 for fixing the bracket 13 to the frame 1, and bolts 16 and nuts 17 for attaching the end of the upper beam 9 to the bracket 13.

Reference numeral 18 denotes a lower mounting bracket that removably attaches the end of the lower beam 10 to the lower part of the rising portion 3 of the frame 1, and this lower mounting bracket includes a plate 19, as shown in FIGS. 10 and 11. U-bolts 20 that cooperate with plates 19 to interconnect the ends of the lower beams 10 across the frame 1;
and a pair of nuts 21 screwed into the U-bolt 20,
It consists of 21.

The figures in Figures 5 to 11 show the appearance in spring, summer, and autumn when there is no snow.
Loosen the bolts 14 and nuts 15 of 2 to make the bracket 13 and frame 1 rotatable, and loosen and remove the U-bolts 20 and nuts 21 of the lower mounting bracket 18 to make the lower beam 10 rotatable. Place the upper mounting bracket 1 as shown in Figure 14.
2 as a fulcrum, the lower beam 10 is rotated upward as shown by the arrow, and fixed to the horizontal portion 5 of the frame 1 using the lower mounting bracket 18. 12 and 13 show a state in which the lower mounting bracket 18 is fixed to the horizontal portion 5 of the frame 1. At this time, the lower mounting bracket 18 is attached to the frame 1, as shown in FIGS. 15 and 16.

In the protective fence configured as described above, when the beams 9 and 10 are rotated upward, the beams 9 and 10 cover the upper part of the green zone. Therefore, if the upper and side sides of the protective fence are covered with sheets or mats 6 as shown in Fig. 17, snow can be collected by removing snow from sidewalks and driveways in the same way as in the previous embodiment. Even when snow is dumped in the green belt, the snow 7 is deposited and retained on the frame 1 and beams 9 and 10, as shown in Fig. 18, and the trees and plants 8 planted in the green belt are protected. It turns out. Also,
This protective fence will function as a normal pedestrian protective fence or an access protective fence except in winter. In this case, as shown in Figure 4, the upper part of the green zone is not covered with beams, so the aesthetic appearance is not spoiled during periods other than winter. Furthermore, since the upper part is not covered by the beam, the growth of trees and plants is less likely to be inhibited, and management such as pruning can be easily performed.

By the way, in the above explanation, the case where this invention is used for green belts of roads and green belts of parks has been described, but it goes without saying that it can also be used for other green belts.

[Effects of the invention] As explained above, with this invention, both the beam and the frame cover the green area, so if the top and sides of the protective fence are covered with sheets or mats, roads and driveways can be cleared of snow. Even if the snow collected is dumped on the green belt, the snow will be deposited on the beam and retained, protecting the trees and plants in the green belt.Moreover, even if the snow disappears in spring, the trees and plants will be protected. Since the plants and trees are not destroyed, there is no need to replant them, and there is no need for extensive maintenance. In addition, when the snow disappears in the spring, simply rotating the upper beam and replacing the lower beam with the rising part of the frame allows you to create a structure with the upper part of the green belt open. It does not spoil the aesthetic appearance.
