Description

[Detailed explanation of the idea] The present invention relates to a snow fence.

Traditionally, snow fences have been removed every year after the snowfall has ended, but recently, as the demand for snow fences has increased, the number of snow fences installed has also increased, and removal has therefore become costly. For this reason, in recent years there has been a shift towards fixed types, which are installed throughout the year.

However, this stationary type also has the following problems.

In other words, snow fences installed along the roadside remain in place even after the winter season, which obstructs the landscape and also creates a sense of pressure on motorists, impeding safe driving. Furthermore, the farmland is in the shade of the snow fence, which has a negative effect on the crops. In order to deal with these shortcomings, recently, after the winter period, each snow protection board that makes up the snow protection fence is lowered until it becomes horizontal, and the spacing between the snow protection boards is widened, so that the front view can be seen clearly through the snow protection boards. By making it visible, it prevents the landscape from being obstructed, eliminates the feeling of pressure on drivers of cars, etc., and minimizes shade by allowing sunlight to pass through the spread snow protection boards. Various ideas have been made.

However, depending on the angle of sunlight,
It is still not possible to prevent the occurrence of shading, and no matter how horizontal the snow protection boards are, for drivers of cars, etc., the smaller the angle of view of the main pillars in front of them, the more they overlap. It can't be avoided that it starts to look like a wall and creates a feeling of oppression. Furthermore, on roads in national parks, etc., it is prohibited to install anything that obstructs the scenery during the summer.

The present invention eliminates the above-mentioned drawbacks, removes all components of the snow fence other than the main pillars and stores them in a lower part, and also removes the parts of the main pillars that exceed the guardrail standard height, thereby improving the landscape. The purpose is to eliminate obstacles, relieve the driver's feeling of pressure, eliminate shaded areas, and obtain a snow barrier that can be applied to national park roads.To achieve this purpose, each main pillar is It consists of an upper and a lower main pillar that are configured to be bendable by a connector, and the main pillar has an upright fixing device that fixes the upper and lower main pillars in this state when both the upper and lower main pillars are in a straight line. Each snow protection board is provided with ear shafts having parallel surfaces parallel to the axis at both ends on which it is attached to each of the above main pillars, and each of the above upper main pillars is provided with a snow protection plate fixing fitting into which the ear shaft is fitted, and has a groove portion that is provided with a retainer and is formed to hold the snow protection plate at a predetermined inclination angle, is formed so that when the adjacent main pillar bends, a fixing metal fitting that receives the tip of the adjacent upper main pillar and fixes it in that position fits with the ear shaft of the snow protection board so that the snow protection board stands upright. The present invention is characterized in that the receiver is provided with a plurality of ear bearing portions for the receiver having groove portions.

Hereinafter, the present invention will be explained based on the accompanying drawings showing one embodiment thereof.

In FIGS. 1A and B, reference numeral 1 indicates a plurality of main pillars erected, and reference numeral 2 indicates a plurality of main pillars arranged vertically in parallel between each main pillar 1. For example, in the present invention, four main pillars are provided. This is a snow protection board, and the snow protection board 2 is supported on the main pillar by a snow protection board fixing fitting 3.

As shown in FIGS. 2 and 3, this snow protection board 2 has snow protection board mounting brackets 4 attached to both ends thereof.
An ear shaft 5 is fixed to the snow protection board mounting bracket 4. Note that the ear axis 5 is the ear axis 5 as shown in FIG. 3B.
A parallel surface 5a parallel to the axis is formed.

Next, as shown in FIG. 4, the main pillar 1 is composed of an upper main pillar 6 and a lower main pillar 7 which are bent in the middle, for example, at the height of the guardrail, and between the upper and lower main pillars 6 and 7, As shown in FIGS. 5A, B and 6A, B, a connector provided at the end of the flanges 6a, 7a fixed at each end, for example,
They are bendably connected by a hinge joint 8, and both flanges 6a and 7a are in contact with each other when they are erected.

Furthermore, fixing fittings 6c and 7c having through holes 6b and 7b are fixed to the upper and lower main columns 6 and 7, respectively, and the upper and lower main columns 6 and 7 are fixed to the flange 6.
The upper and lower main pillars 6 and 7 are fixed by inserting the positioning pins 9 into the through holes 6b and 7b formed so that they are coaxial when they are in a straight line due to abutment of a and 7a. together with both flanges 6a,
7a is fastened and fixed with bolts 10. The upright fixing device 11 is constituted by the fixing fittings 6c, 7c and the positioning pin 9, but the upright fixing device 11 is not limited to the above configuration, and may have any other configuration, for example, shaped steel attached to the upper and lower main pillars. It may also be done by placing it like a tree and clamping it to the upper and lower main pillars.

Further, on the opposite side of the hinge joint 8 of the flange 7a of the lower main column 7, a fixing metal fitting 12 is fixed to support the tip of the adjacent upper main column 6 which has been bent and brought down. For example, a coaxial bolt hole is formed at the tip of the main column 6, and a bolt/nut 13 is passed through this bolt hole and tightened to fix both.

Next, as shown in FIG. 7, the snow-proof plate fixing fitting 3 that supports the snow-proof plate 2 on the main column 1 in a snow-protected state, when the ear shaft 5 of the snow-proof plate 2 is inserted through its parallel surface 5a, A bracket 3a fixing an ear bearing part 3b having a groove part 3c, which is a parallel surface formed so that the snow protection board 2 is held at a predetermined inclination angle for snow protection, is attached to the main column 1 by bolts 14. The groove portion 3c is preferably formed so as to be slightly upward in the horizontal direction or toward the opening side. Further, the groove portion 3 of the ear shaft 5 when the ear shaft 5 of the snow protection board 2 is fitted into the groove portion 3c.
A retaining pin 15, for example, is provided on the opening side of c to prevent the ear shaft 5 from moving toward the opening side, perpendicular to the groove 3c. Note that to prevent the ear shaft 5 from moving, it is not limited to the stop pin 15, but any other means may be used. Furthermore, the snow protection board 2 is formed so that it can be easily fitted into and removed from the snow protection board fixing fittings 3 by fitting the ear shafts 5 and the grooves 3c. As shown in FIG.
snow protection plate fixing fittings 3 are attached.

Next, in the non-snow protection state, the upper main pillar 6 is bent as described above to form the structure shown in FIG. At that time, in order to support the snow protection board 2, the support 1 that supports the ear shaft 5 is
6 is provided on the lower main pillar 7. This money received 16
is fixed or fixed to the surface of the lower main column 7 that faces the adjacent main column, and the ear bearing part 3b that constitutes the snow protection plate fixing fitting 3 is attached to the opposite surface of the support 16.
Receiver ear bearing parts 17 having substantially the same configuration as the above are attached at predetermined intervals. However, the inclination of the groove 17a is such that when the parallel surface 5a of the ear shaft 5 of the snow protection board 2 is fitted into the groove 17a, the snow protection board 2 is installed at an angle so that it stands upright. Note that the provision of the stop pin 18 is similar to that in the snow protection plate fixing fitting 3.

Since the present invention is configured as described above, the fourth
In order to change from the non-snow-protected state shown in the figure to the snow-protected state shown in FIG. After passing the positioning pin 9 through the through holes 6b, 7b, both the flanges 6a, 7a are tightened with bolts 10, and the main column 1 is formed by combining the upper and lower main columns 6, 7 into one. Next, release the retaining pin 18 of the receiver 16 and take out the snow protection plate 2.
When the ear shaft 5 is fitted into the groove 3c of the ear bearing portion 3b of the snow protection board fixing fitting 3 and the stop pin 15 is attached,
The snow protection plate 2 is held at a predetermined inclination angle for snow protection, and becomes in a snow protection state.

In addition, in order to change from the snow-protected state to the non-snow-protected state, the operation is almost the reverse of the above, that is, first, remove the snow protection plate 2 from the main pillar 1 and attach the support plate 1 as described above.
6 to be stored upright, and then the upper main pillar 6 is sequentially brought down from the end via the connector 8, and fixed to the fixing bracket 12 installed on the adjacent lower main pillar 7, thereby making it in a non-snow-proof state. It can be done.

Since the present invention is constructed and operates in this way,
It is extremely easy to install and remove, and can be operated by a small number of workers in a short time, and the snow protection board can be stored at a low height, for example, at the same height as the guardrail.
Furthermore, after the snow protection board is stored between the lower main pillars, the upper main pillars are sequentially bent as described above, so that the snow protection fence when all the work for non-snow protection conditions is completed is, for example, , it is almost similar to a guardrail and can be used as a substitute for a guardrail, and compared to the conventional snow prevention condition where there are many main pillars left standing on the road shoulder, it is more like a guardrail. This is extremely desirable from the viewpoint of traffic safety and aesthetics, and can produce the effect of providing a snow fence that hardly creates any shade.
