Description

[Detailed description of the invention] (Field of industrial application) This invention is a device installed on the roadside to converge wind diagonally on the road surface, blow away snow on the road surface, and thereby ensure traffic safety. Concerning snow-blown snow fences.

(Prior art) Conventionally, this type of blowing snow fence has pillars erected at intervals along the roadside, and four pillars are installed between the pillars.
It is constructed by installing up to eight snow protection boards in a diagonally parallel looper shape at intervals above and below.

(Problem to be solved by the invention) Such a snow blowing fence is necessary during snowfall in winter, but when it is not used outside of winter, it impairs the view and visibility, so the snow prevention board is removed from the support and stored. The problem is that the removal and reinstallation work is troublesome and requires a great deal of effort.

(Means for Solving the Problems) The present invention eliminates the drawbacks of the conventional snow blowing fence as described above, and will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes pillars that are erected along the roadside at regular intervals.
Reference numeral 2 denotes a short column, which is erected along the column 1, and is rotatable outward toward the roadside using its base 24 as a fulcrum. The above pillars 1 and short pillars 2 are shown with details omitted, but are H-shaped, L-shaped, etc.
Shaped steel is used to facilitate the attachment of bolts, pins, etc., and is devised so that the main part 25 of the short column 2 is integrated with the column 1. 5 is a set bolt that fixes the short column 2 to the column 1.

Reference numeral 3 denotes a telescopic member, which is formed by cross-connecting a connecting piece 31 and a plate mounting piece 32 with pins in an X-shaped pantograph shape, as shown in FIG.
The number of cross-connected sets of the connecting pieces 31 and the plate attachment pieces 32 is determined by taking into consideration the number of snow protection plates to be attached thereto. In the figure, the connecting piece 31 and the plate attachment piece 32 are cross-connected so that four snow protection plates can be attached.

The lower end intersection 33 of the telescopic member 3 is rotatably attached to the lower part 22 of the short pillar 2 by a pin bolt, and the upper part 11 of the pillar 1
The upper end crossing portion 33' of the telescopic member 3 is fixed in an extended state by a pin. 23 is short column 2
This is a fastening hole provided in the upper part 21 of the telescopic member 3, and is for fastening the upper end intersection portion 33' of the telescopic member 3 in a contracted state with a pin. Note that the upper part 21 and lower part 22 of the short column 2 expressed here indicate the vertical positional relationship, and the distance between the upper part 21 and the lower part 22 is the same as that when the telescopic member 3 is contracted. The distance approximately corresponds to the distance between the upper end intersection 33' and the lower end intersection 33. Therefore, as long as the above positional relationship is maintained, the upper part 21 and lower part 22 of the short column 2 may be set slightly below the short column 2.

Reference numeral 6 indicates a spacing member installed at the upper end intersection portion 33' of the opposing telescopic members 3, and 7 indicates a hook attached to both ends of the spacing member 6. Note that this spacer 6 may be attached to the upper end of the support column 1, and only the hook 7 may be attached to the upper end intersection 33' of the telescopic member 3.
Further, the spacer 6 may not be used.

The extensible member 3 is attached so as to face each of the columns 1 and short columns 2, and both ends of the snow protection plate 4 are attached to the opposing plate mounting pieces 32 of the extensible member.
It is attached using fittings such as shaped steel pieces or bolts and nuts. By attaching the snow protection plates 4 to the telescopic member 3 in this way, four snow protection plates 4 can be installed between the columns 1.
are installed vertically in a diagonally parallel louver shape at regular intervals to form the snow blowing fence of the present invention.

(Operations and Effects of the Invention) As described above, in the blowing snow fence of the present invention, the snow prevention plates 4 are installed between the pillars 1 via the telescopic members 3 in the form of diagonally parallel louvers at regular intervals vertically. As a result, the wind converges in the diagonal direction of the road surface and the snow on the road surface can be effectively blown away, similar to the conventional snow blowing fence.

When the telescopic member 3 is not in use, a suitable small-sized lift is used, and the upper end of the telescopic member 3 is suspended by hooking the wire of this lift onto the hook 7, for example. Remove the pin and lower it down. Then, as shown in FIG. 3, the extensible member 3 changes from an expanded state to a contracted state due to its own weight, and the snow protection plates 4 attached to it also become small and overlapped.

In this state, the upper end intersection 33' of the telescopic member is
It is pinned to the short pillar 2 at the position of the fastening hole 23 in the upper part 21 of the short pillar 2. After that, by removing the set bolt 5 fixing the support column 1 and the short column 2, and rotating the short column 2 outward toward the roadside, as shown in FIG. The board 4 moves outward to the roadside together with the short pillar 2.

Therefore, when not in use, the snow protection boards can be completely removed from between the pillars, improving views and visibility.
Furthermore, the snow protection boards can be moved from between the pillars to the outside of the roadside by combining each snow protection board into a set using the telescopic member as described above, and when necessary, the snow protection fence can be easily moved by reversing the above operation. It can be assembled and its work is easy.

In addition, as mentioned above, the snow protection boards are moved to the outside of the road when they are not in use, so they do not obstruct traffic and are safe as they will not be blown away or damaged by falling even in strong winds. .
