Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a storage structure of a snow plate in a snow fence that is erected along a road in a snowy area.

[Problems to be Solved by Prior Art and Invention] Generally, this kind of snow fence is installed upright at the road edge in a snowy area in order to prevent snow damage on the road.
In the seasons other than winter, it is not preferable in terms of traffic safety and aesthetics. For this reason, conventionally, the snow-prevention plate of the snow-prevention fence was removed at the end of the winter season and stored in a storage place such as a warehouse, and it was reassembled before the winter season. It was extremely complicated, and it required a lot of manpower, and it was not easy to secure a storage space for the snow plate, which was a problem.

So, like the one in Japanese Utility Model Publication No. 62-15291,
There are some snow protection plates that can be lifted up and down between the left and right guide rails and can be folded and stored above the guide rails except in winter. However, with this one,
Since the snow plate protrudes toward the road side from the guide rail during storage and there is a risk of contact with tall vehicles, it is necessary to install a separate guard member or install the snow plate away from the road. There is a need for improvement.

[Means for Solving the Problems]

SUMMARY OF THE INVENTION The present invention was devised with the object of providing a structure for storing snow plates in a snow fence that can eliminate these drawbacks in view of the above-mentioned circumstances. In the snow protection fence constructed by the guides of the left and right guide rails that can be stored in the upper part of the guide rail in a superimposed manner, the snow protection fence is moved up and down by being guided by the guide rails at the front end portions of the left and right edges of the snow protection plate. A guide roller is provided, the front end of the link is pivotally supported by the support shaft of the guide roller, and the rear end of the link is pivotally supported by the middle portion of the left and right side edges of the snow protection plate adjacent to the lower side. The snow protection boards are connected in series, and the snow protection boards that are stored in an overlapping manner as the lowest snow protection board rises have a front end located at the guide rail portion and a rear end protruding rearward from the guide rail. Structure to be stored It is characterized in that the the.

According to the present invention, the present invention can prevent contact between the snow protection plate and the vehicle without separately providing a guard member or distant from the road.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a snow fence which is erected at a road end in a snowy area, and the snow fence 1 includes left and right columns 3 whose base ends are supported by a foundation 2, and the top of the columns 3 to the front (road). Beam 4 extending in a cantilever manner toward the side), a guide rail 5 fixed to the top end of the beam 4 in the vertical direction, and a plurality of snow protection plates 6 supported between the left and right guide rails 5. It is configured.

Further, 7 is a roller rotatably provided on a support shaft 7a projecting from the lower left and right ends of the snow protection plate 6,
The roller 7 is vertically fitted in the guide rail 5 so that the roller 7 can roll in the vertical direction, so that the snow protection plate 6 can be guided up and down along the guide rail 5. Further, 8 is a link, the lower end of the link 8 is pivotally supported on the left and right side surface intermediate portions of the snow protection plate 6 via bolts 9, while the upper end thereof is adjacent to the upper side of the snow protection plate 6. Is pivotally connected to the support shaft 7a of the above, and thereby the link 8 connects the plurality of snow protection plates 6 in a continuous manner and holds the snow protection plates 6 in the backward tilted posture. The link 8 of the uppermost snow-preventing plate 6 is pivotally connected to a support shaft 10a described later.

On the other hand, 11 is an operation wire, and the operation wire 11
Is suspended on a pulley 10 rotatably provided on the upper end of the guide rail 5 via a support shaft 7a.
One end thereof is locked to the support shaft 7a of the snow protection plate 6 located at the bottom. That is, by pulling down the other end of the operation wire 11 that hangs downward from the portion of the snow protection plate 6, the snow protection plate 6 is sequentially lifted from the lower side, and the guide rail 5
However, since the lower end of the snow-prevention plate 6 is guided by the guide rails 5 at this time, the snow-prevention plate 6 has a posture in which it does not substantially project to the road side from the guide rails 5. It is designed to be stored neatly.

In the embodiment of the present invention configured as described above, a plurality of snow protection plates 6 are located above and below the guide rails 5 in the winter when there is snowfall, but in the seasons other than winter, the guide rails 5 With almost no protrusion in front of
The guide rails 5 are accommodated in the upper portion in a superposed manner.

As described above, in the case where the present invention is implemented, the snow protection plate 6 can be stored on the upper part of the guide rail 5 so that it does not hinder traffic safety and aesthetics in seasons other than winter. However, the stored snow-preventing plate 6 is superposed and stored on the rear side of the guide rail 5 without projecting to the front road side of the guide rail 5 unlike the conventional one. Therefore, the guide rail 6 can be provided immediately beside the road to exert an excellent snow-prevention function without providing a separate guard member or provided separately from the road. It is possible to reliably prevent contact, and as a result, it is possible to provide a snow fence that has excellent safety and has a simplified structure.

Moreover, in the present embodiment, the snow-preventing plate 6 is cantilevered by the pillars 3 standing upright from the road end, so that the snow accumulated under the snow-preventing plate 6 can be easily removed. Perhaps that the snow protection plate 6 can also be used as a road shoulder indicator that displays the road shoulder position in winter. Furthermore, the snow plate 6
Since they are connected and fixed via bolts, the work for replacing the snow protection plate 6 due to damage due to an accident or the like is easy, and the maintainability can be improved.

[Advantages] In summary, since the present invention is constructed as described above, the snow plaque is constructed so as to be superposed and stored on the upper part of the guide rail by the guide of the guide rail. Although it was designed so as not to interfere with the above, the stored snow protection plate has its front end located at the guide rail portion and does not project to the road side at all,
The rear end is stored in a storage posture in which the rear end projects rearward from the guide rail.

As a result, the snow-prevention plate is prevented from projecting significantly forward from the guide rail during storage, so that the guide rail can be set just before the road without the need to purposely provide a guard member or separate it from the road. It is possible to reliably prevent the vehicle from coming into contact with the front end portion of the stored snow-preventing plate while improving the snow-preventing function by standing up the snow-preventing fence, and it is possible to reduce the cost of the snow-prevention fence and improve the maintainability.
