In addition, the snow-proof panel is a pantograph type, and this pantograph-type snow panel is folded small and removed from the pillar and stored in the lower storage part.
No. 928 (conventional example). Also, a pantograph type snow protection panel is lifted by a winch or the like to be folded small, then lowered and stored in the lower storage portion, and the pillar is also stored in the same direction by extending in the road extension direction (JP-A-9-105114 ( Conventional example)). further,
A structure in which the upper and lower snow protection panels do not interfere with each other when the support pillar is tilted in the road extension direction, and the support pillar is tilted in the longitudinal direction of the fence with the snow protection panel attached to store the entire structure (Japanese Patent Laid-Open No. 10-102427).

収納作業に多大の労力を必要とする。Among the above-mentioned conventional snow fences, in the conventional method of manually removing the snow-proof panel of the net, the work of removing or attaching the snow-proof panel of the net is extremely complicated. Further, in the conventional example and the system adopting the pantograph type snow protection panel, the mechanism itself becomes complicated by adopting the pantograph type. Further, the conventional system requires a lifting device for lifting a folded pantograph system, and the conventional system also requires a winch. Therefore, both storage work and preparation work are extremely complicated. Further, in each of these methods, various tools are required, and since there is work at a high place, a ladder or the like is also required, and work cannot be performed if these are forgotten. Also,
In the conventional method of storing the entire snow fence by tilting the props in the longitudinal direction of the fence, not only the structure becomes more complicated, but also
A great deal of labor is required for storage work.

When the snow fence is stored when it is not in use, the storage work can be performed easily and lightly without using a power or a winch, and efficiently. The purpose of the present invention is to provide a snow fence that can be implemented in a specific manner.

に入る姿勢となる。During the seasons other than the winter season when no measures against visibility problems are required, the snow protection panel 8 and the upper support column 3 are housed as shown in FIGS. This storing operation will be described.
The pulley 3 is attached to the shaft 28 at the upper end of the upper split panel 6.
When the wire 35 passed through 6 is loosened, the snow-prevention panel 8 is folded into a dogleg shape as shown in FIGS. At this time, the link 31 includes the upper and lower split panels 6,
7 acts so as to perform a synchronous V-shape.
Immediately before the snow-prevention panel 8 is folded substantially horizontally as shown in FIGS. 6 and 7 and placed on the pedestal 24, as shown in FIG. 9, the snow-prevention panel 8 is rotatable about the shaft 28 at the upper end of the vertical frame 27 of the upper split panel 6. The attached guide member 34 enters the groove of the lower strut rear portion 18 which is the H-shaped steel of the lower strut 2 and is immovably locked. In this case, the weight / stopper 34 a of the guide member 34 functions as a stopper that abuts the vertical frame 27, and the guide member 34 is placed in the groove of the lower strut rear portion 18.

ち上げることができる。When the snow-proof panel 8 is folded, the spring cylinder 25 elastically supports and reduces the snow-proof panel 8 (lower split-panel 7) as the lower split-panel 7 tilts to balance the weight of the snow-proof panel 8. I take the. By the action of the spring cylinder 25, the force acting on the wire 35 that suspends the snow protection panel 8 is small, and the snow protection panel 8 can be easily folded with a small force. Similarly, when the snow protection panel 8 is started up, the force of pulling the wire 35 by the urging force of the spring cylinder 25 is small, and the snow protection panel 8 can be started up with a light force.

働がなく、この点でも作業性がよい。Next, the upper support column 3 is tilted inwardly of the span about the rotary shaft 22 as shown in FIGS. 6, 7, and 9 to make it substantially horizontal. As a result, both the snow-prevention panel 8 and the upper support column 3 are folded and stored, and the overall height of the snow-prevention fence 1 is significantly lowered. Since the height of the snow fence 1 in this folded state is lower than the top of the road fence 12 as shown in FIG. 6, the driver of the vehicle traveling on the road does not obstruct the view at all. This is possible because the snow fence 1 is installed on the slope 13 on the side of the road. Further, when the upper support column 3 is tilted, the counterweight 37 is provided below the upper support column 3, so that the upper support column 3 can be prevented from being tilted by impact, and the upper support column 3 can be tilted with a small force. You can As described above, the snow fence 1 can be put in the stored state by a simple operation of loosening the wire 35 to fold the snow prevention panel 8 and then tilting the upper support column 3 in the road extension direction. The storage work of can be performed very easily and efficiently. Further, the operation of the wire 35 can be performed at a low position close to the ground, and
The tilting operation of the upper column 3 can be performed only at a low place, and work at a high place is unnecessary. Therefore, workability is good without the need for a ladder. Further, since no tools or the like are required, workability is good, and problems such as forgetting tools and being unable to work do not occur. Further, a winch, a lifting device, etc. are not required, and in this respect as well, the storage work is simple and the workability is good. Further, there is no heavy labor such as transporting the winch, and workability is also good in this respect.

After releasing the restraint means (not shown) that restrains the tilted state, the upper support column 3 is rotated about the rotation shaft 22 until the lower portion hits the stopper 20, stands vertically, and then is vertically held (not shown). By means of restraint in a vertical state. Next, the wire 35 is pulled to lift the upper end of the folded snow-proof panel 8 (the upper end of the upper split panel 6), and the snow-proof panel 8 stands up. At that time, the link 31 acts so that the upper and lower split panels 6 and 7 perform a synchronized start-up operation. Subsequently, the H-flange pressing plate 39 (FIG.
When (a) is applied to the upper support column 3, the snow-proof panel 8 rises vertically and becomes a plane. Next, snow protection panel 8
The vertical frame 27 is fixed to the upper column 3 by fixing means (not shown). As a result, the snow fence 1 can effectively perform the snow prevention function. At that time, immediately before the snow protection panel 8 becomes vertical, the guide member 34 at the upper end of the upper split panel 6 is provided.
Is guided by the guide portion 32b of the holding groove member 32 to hold the holding groove 3
It fits in 2a. In that case, the weight / stopper 34a of the guide member 34 acts as a weight to bring the guide member 34 into a vertical posture to enter the holding groove 32a.
