Description

[Detailed explanation of the idea] [Industrial application field] This idea concerns a snow fence.

[Prior Art] Conventionally, the plurality of snow protection plates of this type of snow protection fence have been designed such that the rotation axis of the plate body mounting bracket to which the snow protection plate body of the snow prevention plate is attached and both ends of the vertically adjacent plate body mounting brackets are connected to each other. It constituted a four-bar chain mechanism of the pantograph mechanism, which consisted of two connecting members that connected each. When installing the snow protection board, the slope of the snow protection board body is set by setting the distance between the rotational axes of each board mounting bracket using, for example, a rope.

[Problems to be solved by the invention] Since the conventional device is configured as described above, when raising and lowering the snow protection board, all of the multiple snow protection boards and connecting members are lifted, and the conventional device is constructed as described above. the force required to lift all that weight must be applied to the rope,
There was a problem that hanging work became difficult.

This invention was made in order to solve the above-mentioned problems, and the purpose is to obtain a snow prevention fence that requires less force to lift.

[Means for solving the problem] The snow protection fence according to this invention is configured such that the snow protection boards can be raised and lowered along the main pillar, and one end between the snow protection boards is rotatably connected to the support shaft of the snow protection board. connected, and
An interlocking member whose other end is rotatably fixed to a portion other than the axis of the support shaft of the adjacent snow prevention plate, and is provided with an angle stopper that engages when the angle with the adjacent snow prevention plate reaches a predetermined angle. They are connected by a rope, and lifting and hanging is done by pulling up and down a rope that is fixed only to the top snow protection board.

[Function] Since the snow prevention fence of this invention is constructed as described above, when installing the snow prevention fence, when the rope is lifted, the topmost snow prevention board is pulled up, and by this lifting, the connecting member is pulled up. It rotates and the snow protection board stands up. In this way, when the snow protection plate is erected at a predetermined angle, that is, the optimum angle for snow prevention, the angle stopper comes into contact and prevents further displacement of the snow protection plate and the connecting member.

Until this state is reached, the second snow protection plate remains stored below, and the load lifted by the rope is the top snow protection plate itself, one connecting member, and the top snow protection plate itself. It is only the weight of the rope above the board.

Subsequently, when the rope is lifted, only the second snow protection board is lifted, as in the case of the uppermost snow protection board, and the third and subsequent snow protection boards remain in the stored state.

Repeat this and lift it up.

[Example] This invention will be explained below based on the drawings showing one example of the invention.

In FIGS. 1 and 2, reference numeral 1 denotes a snow prevention plate, and 1a denotes a snow prevention plate that receives the ground snow blowing from the direction of arrow A and blows it away along the slope of the snow prevention plate 1 to blow away accumulated snow on the ground surface. The main body 1b is a plate body mounting fitting to which the snow protection plate body is fixed and has a support shaft 3 for holding the snow protection plate 1 on the support column 2.

The main pillar 2 consists of an upper main pillar 2a and a lower main pillar 2b, and at the connection part, via a hinge 4a,
The upper main pillar 1a is configured so that it can be folded down to the side of the adjacent main pillar, and when installed, can be made to stand upright by fastening the connecting portion. Further, the main pillar 2 is provided with a groove 2c along the main pillar 2, and in this groove 2c,
The support shaft 3 of the snow protection board 1 is formed so that it can be fitted, for example, as shown in FIGS. 3 and 4, through a roller 3a.

Next, reference numeral 4 denotes a connecting member, one end of which is rotatably connected to the support shaft 3, and the other end of which is attached to a portion of the adjacent snow protection plate 1 that is not axially centered on the support shaft 3, for example, the rotation of the snow protection plate 1. The shaft is rotatably fixed at the end in the dynamic radial direction, and as shown in FIGS. 5 and 6, an angle stopper 5 is provided at the end so that the snow protection plate 1 can be rotated at a predetermined angle, that is, at a predetermined angle. When the optimum angle is reached, the slope of the snow protection plate 1 is determined by abutting against the plate body mounting bracket 1b. Of course, the connecting member 4 also has no displacement value.

Further, 6 is a rope, such as a wire rope, whose one end is attached to the uppermost snow protection plate 1, for example, its support shaft 3, and after being hung around a pulley 7 installed at the top of the main column 2, it is lowered. It is routed around and attached to the hoisting machine 8.

Furthermore, 9 is a sub-post provided diagonally along the lower part of the main post 2, and like the main post 1, a groove 9a is provided, and a groove 9a is provided at the end of the bottom snow protection plate 1. The snow protection board 1 is guided so that it can be stored by fitting the rollers 10 therein.

The operation of this embodiment will be explained next.

When installing the snow fence, the upper main pillar 2a is raised from the stored state shown in FIGS. 7 and 8 so that it stands upright in a straight line with the lower end main pillar 1b, and the connecting portions are fastened and fixed.

Next, when the wire rope 6 is hoisted up via the pulley 7 by the hoisting machine 8, the snow protection board 1 to which the end of the wire rope 6 is attached is lifted up, and its support shaft 3 is passed through the groove by the roller 3c. 2c
rise within.

As the snow protection plate 1 rises, both the connecting member 4 and the snow protection plate 1 are rotated and displaced.

Due to this displacement, when the snow protection board 1 assumes a predetermined angle, the angle stopper 5 comes into contact with the board body mounting bracket 1b, making further displacement of the snow protection board 1 and the connecting member 4 impossible. Furthermore, until this state is reached,
The second snow protection plate 1 remains in the stored state.

Subsequently, when the wire rope 6 is pulled up,
Because of the connection member 4 which cannot be displaced, the second snow protection plate 1 is pulled up, and the snow protection plate 1 is tilted at a predetermined angle in the same manner as described above, and the operation is repeated in the same manner.

In this way, the snow protection board 1 at the lowest level is also pulled up, but when it reaches a predetermined angle, the roller 10 at the tip rises within the groove 9a, reaches the top, and stops, completing the installation.

Moreover, when storing, the operation at the time of installation described above can be followed in reverse.

Note that the hoisting machine, etc. in the above embodiments may be any means for hoisting the rope, and the attachment of the connecting member to the tip of the snow protection plate is not limited to the tip, but may be attached anywhere other than the axis of the support shaft. ,
It may be on the opposite side to the support shaft. However, the support shaft to which one end is attached becomes the support shaft of the upper snow protection board.

[Effects of the invention] As described above, according to this invention, only one connecting member is provided between the support shaft and the portion other than the axis of the support shaft of the adjacent snow protection board, and the end on the snow protection board side An angle stopper is provided in the section, which reduces the number of connecting parts and makes it easier to lift and store during installation and storage.
This has the effect of providing a snow protection fence that requires less hanging load and is therefore easier to install and store.
