Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a foldable device in which a plurality of windbreak snowboards are vertically deployed and installed in winter, and the windbreak snowboards can be lowered and stacked in the front-rear direction during periods other than winter. This is a type of vertical split-type windbreak snow fence.

[0002]

2. Description of the Related Art Conventionally, as the (A) vertical split type windbreak snow fence, a windbreak snow fence disclosed in Japanese Utility Model Publication No. 5-27111 is known.

The structure of this snow fence is a snow fence to be built along a road in a snowy area, and a plurality of windproof snow bodies which are long in the road running direction are arranged at predetermined intervals in the vertical direction. The lowermost one of these snow-preventing bodies is made higher than the road surface to provide a blow-through gap, and each of these snow-preventing bodies is formed by an inclined plate-like body inclined so that the road side becomes lower. As a snow body, the wind that blows from the windbreak snow fence toward the road is separated by the lower gap flow that blows on the road surface through the blow-through gap and the gap between each snow body and the upper end of the top main windbreak body. In addition to splitting into the upper separated shear flow, a snow fence is further provided with a sub-snow body.

In the case of this windbreak fence, the main snow bodies which incline downward toward the road side are arranged at intervals in the vertical direction at the lower level and at the upper level above the main snow body. It is a snow-preventing body having a structure in which a sub-snow-preventing body is arranged horizontally or so as to rise on the road side so that the direction is different from the main snow-preventing body.

In the case of the above-mentioned snow-preventing body, even if it has a snow-preventing effect, since it is provided with a horizontally-arranged snow-preventing body, there is a high possibility that snow will be deposited on this portion, and moreover the main snow-preventing body at the upper end level will be deposited. As described above, there is a high possibility that the snow-prevention effect will be lost due to the accumulation of snow, and this is not practical.

On the other hand, (B) As a known prior art, as disclosed in Japanese Patent Publication No. 5-5966, all windbreak snow plates are inclined downward in only one direction toward the road side. There is also known a windbreak snow fence in which the windbreak snowboards are sequentially arranged and folded downward.

In the known technique (B), a pulley is attached to the upper end of a column having an H-shaped cross section supported by a column support member, and a horizontal rod is provided at a widthwise intermediate portion of a windproof snow plate extending in the horizontal direction. Is fixed to form a windproof snow plate unit, and the ends of a plurality of windproof snow plate units arranged at intervals in the vertical direction are connected via a windproof snow plate expansion / polymerization link mechanism to the pulley. In a windbreak snow fence in which a horizontal rod in the uppermost windbreak snow plate unit is connected to a wound lifting strip, it is provided between a guide / holding member extending vertically in the rear part of the pillar and the pillar. A support member fixed to the end of the horizontal rod of each windbreak snow plate unit is disposed in the guide space provided, and the guide member / holding member is supported by a column so that the position can be adjusted in the front-rear direction. Double presser member A vertical guide member that extends vertically in the lower part of the guide space and a tilting support member for storing a bearing member that tilts rearward and downward from the lower end of the vertical guide member. ,
The windbreak snow fence is supported by the column support member, and a stopper is attached to the lower end of the inclined support member for storing the support member.

The windbreak snow fence thus constructed can be easily folded in a downward aligned state when it is not used in summer or the like, and is effective as a measure against snowdrifts on the road due to snowstorms and a visibility problem. , Currently, there are several types of snow fences.

[0009]

Since the structure type (A) is a fixed type, when the main snow cover and the sub-snow cover are removed in the summer or attached in the winter, the snow cover of each snow cover is removed. There is a problem that the removal or attachment work is complicated. Further, as described above, even if the above-mentioned snow preventer has a snow preventive effect, since it is provided with a horizontally arranged snow protector, there is a high possibility that snow will be deposited on this portion, and the main snow protector at the upper level is used. There is also a possibility that the snow will be accumulated beyond the above range, and thus, there is a high possibility that the snow-prevention effect will be lost due to the snow accumulation, which is not practical.

Further, in the case of the conventional windbreak snow fence of the above (B), a strong wind that blows through the lower gap of the fence blows away the road surface of the road and is also effective for mitigating visibility obstacles. Since this wind-swept snow fence converges and accelerates the wind toward the lower leeward side (sidewalk side), the sidewalk side will be a little strong wind, so for pedestrians, there are obstacles to walking. there were. Regarding the visibility at the line of sight when driving a passenger car, in the case of strong wind and snow with a wind speed of about 15 m / s, the conventional blow-off fence may not be able to secure a field of view that allows the vehicle to run with caution.

According to the present invention, there is no risk of snow accumulation, and there is no risk of the snow-preventing effect being lost, and the work of folding down and expanding upward is easy, and the wind-proof snow plate having different inclination directions is provided. The space occupied when the boards are lowered and stacked so that they overlap each other in the front-rear direction can be reduced, and compared to conventional windbreak snow fences in which all windbreak snowboards are tilted in one direction, it is immediately after the fence. The lower part of the can be a windbreak type snow fence that reduces the wind speed to reduce pedestrians' wind damage. In addition, the visibility at the line of sight when driving a passenger car is about 15 m / s. In the case of strong wind, there is a possibility that a conventional windshield fence may not be able to secure a field of view that allows the car to travel with caution, but in the case of the split-type windshield type snow protection fence of the present invention, the wind speed is about 15 m / s. Note even in strong winds To be secured visibility enough to allow running of the vehicle, and an object thereof is to provide a practical lower foldable upper and lower shunt type windshield Yukisaku which can improve the visibility disorder alleviating effect.

On the ring 85 at the end of the rope, the hook 34 at the end of the rope unreeled from the drum or the like of the hoisting and lowering drive device 74.
And the pressing bolts 44 are moved backward to release the engagement with the support member 5, the hoisting / lowering drive device 74 is slightly hoisted to operate the windbreak snow plate 4. In the state where the engagement between each of the supported stoppers 13 and each of the uppermost support members 5 is released, the stopper rotation through hole 13a of each stopper 13 has an engagement projection 85 as shown in FIG. The engagement protrusion 85 of the rotary operating rod 86 is fitted to rotate the stopper 13 toward the temporary stopper support protrusion 15 side. In the stopper 13 at this position, the rotation moment (the moment to tilt toward the front flange side of the support column 2) due to its own weight in the forward direction about the stopper pivot attachment spindle 14 is in the backward direction (the guide / holding member 28 side). Since it is larger than the moment due to its own weight that tries to tilt to (), it is biased toward the temporary stopper support projection 15 side and does not return to its original position.

Then, the hoisting / lowering driving device 74 is operated for hoisting. By doing so, each windbreak snow plate 4 descends, and each supporting member 5 descends in the guide space 6,
Since each supporting member 5 abuts the lower inclined guide plate 29b and is downwardly guided rearward, the upper link 53 and the lower link 54 connecting between the windbreak snow plate units 9 and 10 are changed from the vertical state to the inclined state. After the transition, the links 53 and 54 generate a downward turning moment due to their own weight. However, when the links 53 and 54 are in a tension state when descending and are larger than the downward turning moment due to the link own weight, the stopper 19 The bearing member 5 abuts, or the following bearing member 5 strikes the bearing member 5,
When the tension state of the links 53 and 54 comes to be released, the links 53 and 53 are lowered and rotated by their own weight. Then, the supporting members 5 attached to the lower windbreak snowflakes 4 adjacent to each other in the vertical direction hit the inclined support member 12 and slide on the inclined support member 12 toward the low level side to stop, and then the upper windbreak. As the snow plate 4 descends, the horizontal axis 8 of the upper link 53 attached to the upper windbreak snow plate 4 moves inside the elongated hole 65 of the lower link 54 attached to the lower windbreak snow plate 4 into the link end portion. From the center to the center of the bending point, while the links 53 and 54 push down the horizontal shaft 8 due to their own weight while moving from the center to the link middle side, It is lowered and rotated around the center, and is automatically housed in the inclined support member 12 in a state where all the windbreak snow plates 4 are stacked in the front-rear direction.

After each windproof snow plate 4 is stored, a connecting rod 89 and a bolt 848, which are fixed to the upper part of the support 2 by an L-shaped support fitting 87 fixed by a bolt 84 and connect the support 2, are removed. Then, the connection between the column 2 and the column support member 1 is released, the fixing bolt 82 at the lower part of the column is removed, and then each column 2 is rotated about the horizontal axis 17 by about 90 degrees as shown in FIG. Of the steady-state bolt 80 which is laid down so as to be placed on the upper connecting member 72 and which is attached to the web 27c of the support column 2 by a pair of nuts so as to be able to move back and forth on the side opposite to the upper connecting member 72 in the left-right direction. The head 81 is brought into contact with the lower surface of the upper end connecting member 71 of the column support member 1,
