Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windbreak snow fence for preventing wind and snow damage on a motorway in a snowfall region, for example.

[0002]

2. Description of the Related Art Conventionally, in a snowfall region, particularly in a snowstorm area, a windbreak snow fence is continuously installed on the windward side of the road to prevent snow accumulation on the road and secure traffic during winter. Is being carried out. The basic structure of this windbreak snow fence is
The pillars are erected along the road at a certain interval, and a plurality of panels are horizontally installed between the pillars. Each panel is tilted at an appropriate angle to the ground,
As a result, during the wind and snow, the snow flow passes from the windward side between the panels along the panel surface to increase the wind speed, and the snow is blown over a long distance over the road or blown off on the road. Therefore, snow accumulation on the road can be avoided.

It is desired to remove such a windbreak snow fence from the reason other than the snowfall period in order to secure the scenery. Therefore, several windshield snow fences of the lower storage type are currently being developed. For example, JP-A-64-36808, JP-A-64-39404, and JP-A-64-58.
No. 705, Japanese Patent Laid-Open No. 64-58706, Japanese Utility Model Laid-Open No. 2-6713, and Japanese Utility Model Laid-Open No. 4-12519 disclose a pulley in which a wire rope fastened to a panel member is provided at the upper end of a column. There is described a windbreak snow fence in which the panel member is lifted up and down along a guide groove provided in a support by hanging the wire rope up and down by lowering the hanging lower end of the wire rope.

The development of the windbreak snow fence is performed by pulling the wire rope to raise the panel member stored below to a predetermined position, and then mooring the wire rope at the hanging end and the column. It is carried out by inserting a mooring bolt across the member. Further, in this unfolded state, the panel member is clamped and fixed to the column by the tightening bolt.

To store the windbreak snow fence, after removing the tightening bolts and the mooring bolts, the panel member is lowered below the columns while supporting the wire rope, and the wire rope is locked at a predetermined position. It will be done.

[0006]

However, in the structure of the conventional windbreak snow fence as described above, the wire rope, which is a means for raising and lowering the panel member and a means for holding the panel member in the expanded state, is a windbreak snowbreaker. A panel member is integrally formed between each of the columns of the fence. When deploying such a windbreak fence, it is not impossible at all to pull the wire rope to raise the panel member only by human power, but at the bottom of the pillars along the side of the road. The work of deploying the stored panel members one after another requires a considerable amount of work in view of the weight of the panel members, and normally, some kind of power means is used to pull the wire rope.

Further, the panel member is fixedly held at a predetermined position only after the wire rope is pulled to raise the panel member and then the hanging lower end of the wire rope is anchored to the mooring member. In this way, the wire rope is a half-finished device that cannot be used as a lifting means or a holding means by itself, and in view of the number of members of the windbreak snow fence, panel members are installed between the columns of the windbreak snow fence. It is disadvantageous in terms of cost to integrally configure with.

Further, in the conventional windbreak snow fence, the panel member cannot be lifted and held without the wire rope. However, this wire rope is not only when the windbreak snow fence is unfolded but also when it is stored. Since it is always exposed to the outside, there is a problem that it is easily deteriorated.

The developed state of the windbreak snow fence is maintained by the wire rope and the mooring member. However, if the wire rope breaks for some reason, the panel member will drop. Tightening bolts are attached to the panel member and fixed to the column. However, the attachment of the tightening bolt is a work performed manually after the panel member is lifted to a predetermined height by the wire rope.

The height position of the panel member fixedly held at the uppermost position is considerably higher than the height of a person. Therefore, if a tightening bolt is to be attached to the panel member, first of all, it is located near the column. Place a means such as a ladder or stepladder on it, and climb it. After completing the installation of the tightening bolts for one column, move a means such as a ladder or stepladder to the next column and perform the same bolt installation work. By repeating this work, the bolt mounting work for all the columns is completed. In this way, the installation work of the tightening bolts is considerably troublesome, and if the installation work of the bolts of all the columns is performed with a small number of people,
Not only is it troublesome, but it also takes a considerable amount of time.

Further, in the structure of the windbreak snow fence, when the windbreak snow fence is housed, the tightening bolts must first be removed to move the panel member downward. At this time, as in the case of unfolding, a means such as a ladder is required, which is very complicated.

In view of the above problems, it is a primary object of the present invention to obtain a windbreak snow fence in which storage work and deployment work can be performed easily and efficiently. Another object of the present invention is to obtain a windbreak snow fence that can ensure safety during deployment and storage work. Still another object of the present invention is to obtain a windproof snow rack that can completely secure the landscape during storage.
Yet another object of the present invention is to provide a windbreak fence which can be protected from outside influences so that deterioration of the members during storage is reduced.

[0013]

In order to achieve the above object, in the windbreak snow fence according to the invention as set forth in claim 1, the panel member housed between the columns is provided in the movement guide portion provided on the columns. A windbreak snow fence formed by holding the panel member at a predetermined height position by moving it upward along a holding means for holding the panel member. In addition to being engaged, the movement guide portion is configured to be capable of passing upward in the panel member.

Further, in the windbreak snow fence according to claim 2, in the windbreak snow fence according to claim 1, the panel member is
It has a plurality of panels connected to each other, and the retaining means retains the panel member by engaging at least the uppermost panel of the plurality of panels.

Further, in the windbreak snow fence according to claim 3, in the windbreak snow according to claim 1 or 2, the holding means includes a support portion that engages with the panel member in the movement guide portion. A supporting member is provided, and the supporting member allows the support portion to rotate upward from a state of holding the panel member, and rotates upward from the state of holding the panel member by a predetermined angle. In this state, the support portion is configured to retract from the movement guide portion.

Further, in the windbreak snow fence according to claim 4, in the windbreak snow fence according to claim 3, the holding means moves upward from a state of holding the panel member with respect to the support member. It is characterized by having a detachable weight for applying a rotational force for movement.

Further, in the windbreak snow fence according to claim 5, the windbreak snow fence according to claim 1, 2 or 3, further comprising a storage portion formed of a side groove provided on a side of the road, The base portion is disposed in the storage portion and is configured to be tiltable in the longitudinal direction of the side groove in the storage portion, and the movement guide portion is continuously formed up to the base portion of the column, It is characterized in that the panel member is housed in the housing part while being moved to the base part along the movement guide part.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION The windbreak snow fence according to claim 1 of the present invention is formed by holding a panel member at a predetermined height position between columns. A movement guide portion is provided in the vertical direction of each column, and the panel member can be moved along the movement guide portion. The movement guide portion may be configured so as to move along the support when the panel member is moved up and down. For example, rails and grooves,
Guide ribs and the like are possible.

A holding means for holding the panel member is provided at a predetermined height position of the support column or the movement guide portion, and the holding means engages with the panel member at the movement guide portion to allow the panel member to be held. Can be held. Further, the holding means is a means that enables the movement guide portion to pass upward of the panel member.

That is, the holding means has a state in which the movement guide portion is engaged with the panel member (referred to as an engagement state) and a state in which the movement guide portion can pass upward in the panel member (passage state). There are at least two states. The holding means may be at least the panel member that moves upward in the movement guide portion to reach the height position where the holding means is provided, and is in a passing state when further rising beyond this position. .

Therefore, when the panel member continues to move from the lower side to the upper side along the moving guide portion extending in the up-down direction of the supporting column in the passing state of the holding means, the panel member is set at the height position where the holding means is provided. Can pass through and move further upward. If the holding means is brought into the engaged state after the panel member moves above the holding means, the panel member engages with the holding means even if the upward force applied to the panel member is released. Then, the support is fixedly held at a predetermined height position. That is, if at least an effort is required to raise the panel member above the holding means, the panel member can be engaged with the holding means and brought into a fixed holding state.

Therefore, in the windbreak snow fence of the present invention, the panel member housed between the columns is moved upward along the movement guide portion provided on the columns and passes through the holding means. A mechanism capable of engaging the panel member with the holding means can be configured, and a windbreak snow fence in which the panel member is easily held at a predetermined height position is formed.

As described above, the holding means for the windbreak snow fence of the present invention, such as a bolt provided in the movement guide portion, has the holding means detached when the panel member is moved upward, and the holding means for holding the panel member. This is a configuration that does not require any labor or time-consuming work of attaching the holding means, such as attaching when engaging with. That is,
The windbreak snow fence of the present invention can be constructed by simply moving the panel member, so that workability is improved.

Incidentally, the movement of the panel member in the windbreak snow fence along the movement guide portion is carried out by the lifting means integrated with the windbreak snow fence of the present invention or a separately prepared lifting means (a crane or the like). It can be easily implemented by using. Since the panel member moved upward by the lifting or lifting force of the elevating means is fixedly held by engaging with the holding means in the movement guide section as described above, at this point, the panel member is no longer suspended by the elevating means. No lifting or lifting force is required. Therefore, in the windbreak snow fence of the present invention, the elevating means does not necessarily have to be permanently installed in each of the columns as a structure of the windbreak snow fence. Since it is only necessary to prepare another elevating means during the work such as installation, the structure of the fence is simplified as compared with the prior art.

Here, in a normal windbreak snow fence, a plurality of panels are held at different height positions between one pillar. When the plurality of panels arranged in the vertical direction are individual as described above, the holding means may be provided at each height position. Then, the wind-proof snow fence is formed by sequentially moving the panels stored above the columns between the columns from the top to the top and engaging the respective holding means.

According to the second aspect of the present invention, if the panel member has a plurality of panels connected to each other, when the panel members are moved upward, the entire plurality of connected panels are You can move it all at once.

Further, since the holding means is to hold the panel member by engaging with the uppermost panel of at least a plurality of panels, the entire panel member housed below the support columns can be completely covered. The uppermost panel is engaged with the holding means because the holding means is engaged after the uppermost panel has passed through the holding means and moved upward along the movement guide portion. However, at least the uppermost panel is held at a predetermined height position. In the present invention, since a plurality of panels are connected, if the uppermost panel is fixed, the other panels are also fixed in a connected state.

For example, if a plurality of panels are connected by a predetermined link mechanism, the plurality of panels are configured so that a predetermined interval is maintained along with the link mechanism, and the respective panels are linked together. It is also possible to change the angle.

Therefore, if the uppermost panel is fixedly held by the holding means as described above, the other panels are held at their respective height positions depending on the connection state, and the windbreak snow fence is It is formed. in this way,
If multiple panels are connected, a windbreak snow fence can be formed if there is only one holding means for the topmost panel, the fence structure is simplified, and the work to form the windbreak snow fence is also very simple. Will be things.

The holding means is not limited to one that engages with the uppermost panel of the plurality of connected panels, and may be provided at a height position that engages with other panels. For example, in addition to the holding means for the top panel,
A holding means for the lowest panel may be provided. In this case, compared to the case where the holding means is provided only for the uppermost panel, the weight of the whole holding means of the panel member and the link mechanism is dispersed, so that the load is reduced and the movement of the entire panel member is reduced. Retaining in the guide part is strengthened, and it becomes a more stable windbreak snow fence.

Further, in the invention described in claim 3, the holding means has a support member having a support portion which engages with the panel member in the movement guide portion. That is, the holding means holds the panel member by the support portion of the support member engaging with the panel member in the movement guide portion. When the support member is in a state of holding the panel member (called a panel holding state), the support portion of the support member stays in the movement guide portion. This panel holding state is the most stable state (equilibrium state) for the supporting member, and when the external force does not act on the holding means, the supporting member is in the panel holding state.

Further, since the support member of the present invention is allowed to rotate upward from the panel holding state in the support portion, when a predetermined external force is applied to the support member,
The support member changes from a stable panel holding state to a state in which the support portion rotates upward. Further, when the support member is rotated upward by a predetermined angle from the panel holding state (referred to as a panel passing state), the support portion is configured to retract from the movement guide portion. This retracted state means that the panel can pass through the movement guide portion. Therefore, when the support member is in the panel passing state and the support portion is retracted from the movement guide portion, the panel member passes vertically along the movement guide portion even at the height position where the holding means is provided. can do.

That is, the holding means of the present invention has a support member in which the equilibrium state is the panel holding state, and when a predetermined external force is applied, the holding means is rotated by a predetermined angle to be in the panel passing state. .

Therefore, when the panel member moves to the height position where the holding means is provided by moving from the lower side to the upper side along the movement guide portion, even if the support member is in the panel holding state, the panel member is held. The supporting portion of the support member is pressed upward by the force of the upward movement of the support member, and the support member rotates in that direction. Therefore, the panel member can continue to move upward as it is. As a result, when the support member is in the panel passing state, the panel member passes through the holding means and is moved above the predetermined height position.

At this time, since the supporting member is not receiving the force due to the upward movement of the panel member, it returns to the panel holding state again. Therefore, since the panel member can be engaged with the support portion of the support member, the panel member is fixedly held at the predetermined height position of the support column.

When the panel member fixed and held at a predetermined height position of the columns is to be stored below the columns,
As described above, the support portion of the support member cannot be pressed upward by the force of the upward movement of the panel member, but if a corresponding external force is applied to the support member by hand, the support portion is similarly moved. Can be evacuated from. Therefore, it is possible to pass the panel member downward, and the panel member is moved downward along the movement guide portion to pass the position where the supporting member is provided, and is moved to a position between the columns to be stored. be able to.

Further, in the invention described in claim 4, the holding means detachably has a weight for giving a rotational force to the support member for rotating the support member upward from the panel holding state. When this weight is attached to the holding means, the supporting member is given a rotational force to rotate upward from the panel holding state. The mass of the weight and the mounting position are determined in advance in consideration of the structure of the holding means so that the mounting of the weight causes the support member to rotate upward from the panel holding state by a predetermined angle (to enter the panel passing state). Good. That is, if the weight is attached to the holding means, the support portion is retracted from the movement guide portion when the panel is not held.

Therefore, when the panel member fixedly held by the holding means is to be stored below the columns, the panel member engaged with the support portion is temporarily moved upward with the weight attached to the holding means. By releasing the weight applied to the holding means by the panel member, the support portion can be retracted from the movement guide portion. Therefore, it is possible to pass the panel member downward, and the panel member is moved downward along the movement guide portion to pass the position where the supporting member is provided, and is moved to a position between the columns to be stored. be able to.

Here, the procedure for attaching the weight to the holding means is not limited to the above, but the panel member engaged with the supporting portion is once moved upward to release the weight applied to the holding means by the panel member. Later, even if the weight is attached to the holding means,
Similarly, the support portion can be retracted from the movement guide portion.

As described above, since the holding means of the present invention has the weight, the holding means should be removed when the panel member fixedly held by being engaged with the holding means is to be housed below the columns. Instead, the workability is improved because the weight can be attached to the support member and the panel member can be stored as it is by simply lowering it.

Further, in the process of moving the panel member from the lower side to the upper side and supporting it by the supporting member, the supporting portion of the supporting member is pushed upward by the force of the upward movement of the panel member and is rotated, so that the weight is Need not be attached to the holding means.

As the accommodating portion for accommodating the panel member below the columns, a guide portion extending vertically or obliquely downward from the lower end portion of the moving guide portion provided on the columns is used as in the conventional example. It can also be used.

In the invention according to the fifth aspect, the storage portion is formed of a side groove provided on the side of the road, the base of the pillar is disposed in the storage portion, and the storage portion can be tilted in the longitudinal direction of the side groove. Since it is configured as described above, it is possible to completely fit the column into the side groove without storing it by exposing the column by tilting the column during storage. Also, the support
You can unfold it from the storage just by standing up.

Further, since the movement guide portion is continuously formed up to the base of the column, at the time of storage, the panel member can be stored in the storage simply by moving the panel member along the movement guide to the base. . Further, at the time of unfolding, the stored panel member can be unfolded from the housing portion by moving it upward from the movement guide portion formed on the base portion of the column as it is.

According to this structure, since the support pillar and the panel member are both housed in the housing formed by the gutter, there can be left no obstacles to the scenery on the side of the road, and the scenery can be almost perfect. Can be secured.

If the storage portion is provided with a lid member, the upper opening of the storage portion can be covered with the support and the panel member stored, so that the storage state can be maintained while the windbreak snow fence is stored. Is covered and looks good, and you can get a better view.

Further, since the contents themselves are protected by the lid member from external influences such as wind and rain and flying stones from the road, deterioration and damage of the windbreak snow fence member during the storage period can be reduced. Further, an accident that a person or a wheel gets stuck in the opening of the storage section is avoided, and safety is secured.

A series of operations such as tilting / standing of the column, movement of the panel member along the movement guide portion, and opening / closing of the lid member may be automatically controlled by using a predetermined power means. If so, efficient storage can be achieved in a shorter time. Of course, tilting / standing up of the pillars and opening / closing of the lid member may be performed manually.

The present invention will be described below with reference to more specific embodiments. FIG. 1 is a schematic view showing a windbreak snow fence according to an embodiment of the present invention installed on the side of a road on the windward side. FIG. 2 is a detailed view of the windbreak snow fence of the present embodiment in a deployed state as seen from the side. FIG. 5 (a)
The detailed view which looked at the side where the windbreak snow fence of this embodiment was stored, and (b) are front views.

The windbreak snow fence according to the present embodiment, as shown in FIG. 1, has a gutter-shaped storage portion 1 provided along the road beside the road and a predetermined lengthwise direction in the storage portion 1. Columns 2 standing upright with a certain distance, and adjacent columns 2
It is mainly composed of a plurality of panels 3 which are horizontally arranged between them.

The base 2 of the support column 2 is provided at the bottom of the storage unit 1, and the connecting portion 6 with the base 5 is located at a position lower than the upper opening of the storing unit 1. It is configured to be tiltable in the longitudinal direction of the storage unit 1 around the center of rotation. When installing a windbreak snow fence, install a panel 3 between the columns 2.
Although the column 2 does not tilt easily when it is laid horizontally, it is advisable to provide a tilting prevention mechanism for reinforcing or fixing the part at the connecting portion 6 with the base 5 so that wobbling does not occur. . Further, a guide rail 7 as a moving guide portion is provided on the side surface of the support column 2 in the vertical direction, and is continuously formed to the base portion 5.

Guide roller shafts 9 are provided at both ends in the longitudinal direction of each panel 3 so as to project from the vicinity of the middle in the width direction. As shown in FIG. 3, a guide roller 31 is engaged with the guide roller shaft 9 near the tip thereof, and a bander arm 8 described later is rotatably engaged with the guide roller shaft 9.

The guide roller 31 is inserted into the guide rail 7 of the column 2, and the guide rail 7 has a lip groove shape. Since the opening width of this guide rail 7 is smaller than that of the guide roller 31, the panel 3 is
It is configured to be movable in the vertical direction along with, and is prevented from coming off from the column 2. As described above, since the guide rail 7 is continuously formed up to the base portion 5 of the column 2, the plurality of panels 3 are moved to the base portion 5 along the guide rail 7 and stored in a stacked state. It can be stored in the unit 1 (see FIG. 5).

In the windbreak snow fence of the present embodiment, four panels 3 are laterally bridged between one pillar 2 at predetermined height positions. These four panels are connected at intervals in the vertical direction via a predetermined link mechanism, and these constitute the panel member of the present invention. For example, as shown in FIG. 2, a bander arm 8 as a link mechanism is rotatably engaged with the guide roller shaft 9 of the panel 3, and the tip ends 81 and 82 of the bander arm 8 are adjacent to each other. It is connected near one end in the width direction at the end of another panel.

That is, since the panel members of this embodiment are connected as described above and the guide rollers 31 of the respective panels 3 are inserted into the guide rails 7, the entire guide rails remain as a unit. It is possible to move up and down along 7. When the panel member is moved to the base portion 5, it can be folded and stored in the storage portion 1 in the state shown in FIG.

On the other hand, when deploying the windbreak fence as shown in FIG. 2, the uppermost panel 3 of the panel members is used.
Is held by engaging the guide roller shaft 9 with an upper stopper 10 provided at a predetermined height position of the guide rail 7. The lowest panel 3 among the panel members
The guide roller shaft 9 is held by the lower stopper 11 provided at a height position below the upper stopper 10 by a predetermined distance. That is, the panel member is fixedly held at the predetermined height position of the support column 2 by the upper stopper 10 and the lower stopper 11 which constitute the holding means of the present invention.

At this time, each panel 3 is held with its panel surface at an appropriate angle with respect to the ground. This angle is set to an optimum condition such that snowfall entering between the panels from the windward side is blown off over the road at a longer distance, or blown off on the road. In the case of the present embodiment, the angle of the panel surface with respect to the ground is determined by the length of the bander arm 8 connecting the panels and the distance between the upper stopper 10 and the lower stopper 11.

Here, both the upper stopper 10 and the lower stopper 11 have the same structure. The structure of the stopper according to the present embodiment will be described with reference to the top view (a) and the side view (b) of FIG. 4 regarding the stopper attached to the right column. The stopper is configured to engage with the guide roller shaft 9 of the panel at the supporting portion 42 of the fixing member 41 that constitutes the supporting member.

The fixing member 41 is made up of the columns 2 (guide rails 7
By the pedestal member 44 and the locking member 45 fixed at a predetermined position (on the side of), the state in which the guide roller shaft 9 of the panel can be engaged, that is, the locking portion 42 is the slit opening portion (guide roller) of the guide rail 7. It is held in a state of staying in the axis passage locus) (called a panel holding state).

That is, the fixing member 41 sandwiches the center of gravity of the combined mass including the mass of the fixing member 41 and the mass of the connecting rod 46, which will be described later, and the pedestal member 44 on the shaft portion 43 opposite to the supporting portion 42. Is supported by. For this reason, the fixing member 41 internally has a rotational force for rotating the supporting member 42 side of the fixing member 41 downward, but since the reaction force against this rotational force is imparted by the locking member 45, the panel holding Held in a state.

The panel holding state is the equilibrium state of the fixing member 41, and if a rotational force such that the supporting portion 42 side of the fixing member 41 is rotated upward is applied from the outside, the shaft portion 43 is used as the rotating shaft. The support portion 42 rotates in the upward direction.

When the fixing member 41 is rotated upward from the panel holding state by a predetermined angle, the supporting portion 42 is substantially retracted from the slit opening portion of the guide rail 7 (referred to as a panel passing state). 41A of the fixing member). At this time, the guide roller shaft 9 can move up and down along the guide rail 7 even at a predetermined height position where the fixing member 41 is provided.

Here, the rotation of the fixing member 41 to the panel passing state is a state in which the panel 3 is allowed to move, that is, in the present embodiment, as long as the guide roller shaft 9 is retracted to such an extent that it can move. Good.

Then, the supporting portion 4 of the fixing member 41 described above.
When the rotational force that causes the second side to rotate upward is released, the fixing member 41 returns to the panel holding state again.

Here, consider the case where the panel moves from below to above the height position of the fixing member 41.
When the guide roller shaft 9 of the panel that has moved upward reaches the height position where the fixing member 41 is provided, the fixing member 41 is in the panel holding state, but the force based on the upward movement of the guide roller shaft 9 is generated. Since the support portion 42 side of the fixing member 41 is pressed upward by, the fixing member 41 rotates in that direction.

When the guide roller shaft 9 continues to move upward as it is, the fixing member 41 continues to rotate further, and the supporting portion 42 gradually retracts from the slit opening portion of the guide rail 7. When the fixing member 41 is in the panel passing state (see the fixing member 41A in FIG. 2), the guide roller shaft 9 passes through the height position where the fixing member 41 is provided and moves upward.

If the guide roller shaft 9 moves upward from the height position where the fixing member 41 is provided, no external force is applied to the fixing member 41, and the panel holding state is restored again. After that, if the panel is lowered, the guide roller shaft 9 can be engaged with the support portion 42 of the fixing member 41. That is, the stopper of the present embodiment is configured to be released by utilizing the force based on the upward movement of the panel (guide roller shaft), and to hold the panel in the equilibrium state in which the external force is not applied. .

On the other hand, when the panel (guide roller shaft 9) is moved downward from above the height position of the fixing member 41, the guide roller shaft 9 reaches the height position where the fixing member 41 is provided. Before this, the fixing member 41 may be changed from the panel holding state to the panel passing state.

In the present embodiment, two stoppers (upper stopper 10 and lower stopper 11) are provided for each column,
The fixing members of the respective stoppers are provided at predetermined height positions, and the connecting members 46 (12 in FIG. 2) are connected to each other on the side 47 opposite to the supporting portion 42 with the shaft portion 43 interposed therebetween.
Are connected via

When a predetermined weight is attached to the connecting rod 12, the fixing members of the stoppers 10 and 11 are rotated upward by a predetermined angle from the panel holding state to the panel passing state. Therefore, when lowering the panel, if a weight is attached to the connecting rod 12 as needed, the two upper stoppers 10 and the lower stoppers 11 can be brought into the panel passing state at the same time.

The windbreak snow fence of the present embodiment having the above configuration can be easily deployed and stored by the following operations. As shown in FIG. 5, the column 2 and the panel 3 are stored in the storage unit 1. 6 and 7 for the process of deploying the windbreak fence from this stored state
This will be described with reference to FIG.

First, as shown in FIG. 6 (a), the left supporting column 2a is rotated at the connecting portion 6a to stand up by using a predetermined power means 60 such as a crane, and the A portion of FIG. 6 (a) is used. As shown in the enlarged view of FIG. 6B, a tilt prevention mechanism, such as fastening a hexagonal bolt 50, is provided and fixed at the connecting portion 6a with the base 5a. Similarly, the right column 2b
Also, it is erected, and is fixed to the connecting portion 6b with a tilting prevention mechanism (FIGS. 6C and 6D). Here, in the present embodiment, both of the columns 2a and 2b are configured to be capable of inclining inwardly, and therefore, if the panel is laid horizontally between the columns as will be described later, it is difficult to incline. It is not necessary to provide a prevention mechanism, but the upright of the column is strengthened and stabilized.

After the columns 2a and 2b are fixed upright, the panel member folded and stored in the storage portion is unfolded by the operation shown in FIG. 7 as shown in FIG. 6 (c). Here, in order to move the panel member in the vertical direction along the guide rail 7, a predetermined panel elevating means 70 such as a crane is used. It is preferable that the panel elevating means 70 directly supports the lowest panel among the panel members, suspends the entire panel member, and vertically moves along the guide rail 7.

First, as shown in FIG. 7 (a), the entire panel member is guided by the guide rails 7 by the panel elevating means 70.
When it is moved upward along the direction, the fixing member of the lower stopper 11 is first rotated by the guide roller shaft 9 of the uppermost panel to be in the panel passing state, and the uppermost panel passes through the lower stopper 11. Similarly, the following three panels sequentially pass through the lower stopper 11.

Further, the entire panel member moves upward, and as shown in FIG. 7 (b), the fixing member of the upper stopper 10 is rotated by the guide roller shaft 9 of the uppermost panel 3, and the uppermost panel 10 is rotated. Pass only the top panel. At this time, since the fixing member of the upper stopper 10 has returned to the panel holding state, by moving the entire panel downward by the panel elevating means, as shown in FIG. 7C, the guide of the uppermost panel is obtained. The roller shaft is engaged with the support portion of the fixed member of the upper stopper 10.

If the panel elevating means is moved downward as it is, the other three panels move downward by their own weight while the uppermost panel is fixedly held by the upper stopper 10, so that the panel member is expanded. Will be done (Fig. 7
(C)). Here, since the fixing member of the lower stopper 11 has already returned to the panel holding state, when the lowest panel engages with the supporting portion of the fixing member of the lower stopper 11, the expansion of the panel is completed.

The windproof snow rack thus installed (FIG. 2)
Has a function of preventing snow from being accumulated on the road during the snowfall period, but is stored in the storage unit 1 after the snowfall period. The storage operation is as follows. First, as shown in FIG.
Connecting rod 1 between the upper stopper 10 and the lower stopper 11
Attach the weight 71 to the 2. Then, as in the case of unfolding, the panel elevating means 70 directly supports the lowest panel 3 and moves the lowest panel upward. At this time, the panel member is gradually folded.

When it is moved further upward, as shown in FIG. 8B, the fixing member of the upper stopper 10 is rotated by the guide roller shaft 9 of the second panel from the top.
That is, the load of the guide roller shaft of the uppermost panel on the upper stopper 10 is eliminated. Since the weight 71 having a predetermined mass is attached to the connecting rod 12, not only the upper stopper 10 but also the lower stopper 11 are automatically brought into the panel passing state, and thereafter this state is maintained.

Thereafter, as shown in FIG. 8C, the panel member is moved downward along the guide rail 7 by the panel elevating means to pass the upper stopper 10 and then the lower stopper 11. Finally, when the base member is reached, the panel member is stored in the storage unit (state of FIG. 6C).

When the panel member is stored, the weight 71 is removed from the connecting rod 12, and both columns are stored in the reverse process of FIG.
That is, if the tilt prevention mechanism is provided, first, remove it, and then tilt the right support 2b around the connecting portion 6b with the base 5b as the center of rotation so that the support 2b extends along the longitudinal direction in the storage unit 1. Store. Next, the left column 2a is similarly stored (state of FIG. 5). As can be seen from FIG. 5B, if the height of the support column and the width of the panel are set to be approximately the same or less, the panel and the support column can be spatially efficiently arranged along the longitudinal direction of the storage unit 1. Is stored.

After the above-mentioned storage work is completed, almost all the members constituting the windbreak snow fence are stored in the storage section, and there is nothing left on the side of the road that damages the scenery. In the present embodiment, since the storage part is provided with the lid member, by covering the upper part of the storage part with the lid member after the panel member and the support are stored in the storage part, during the storage period, that is, the next snowfall. For a long period of time, it will be protected from external influences such as wind and rain and flying stones from the road, so that deterioration of the members can be prevented and there is no danger of people or wheels getting stuck in the gutter.

As described above, in the windbreak snow fence of the present embodiment, the panel member is not moved from the support pillar but is moved vertically along the support pillar to be unfolded and stored in the storage portion collectively. Therefore, the workability is improved.

Furthermore, in the windbreak snow fence of the present embodiment, assembly and storage can be performed only at the installation site, there is no need to secure another space for storage, and the labor required to carry the storage space to another storage site. Is not necessary either.

Further, in the conventional windbreak fence, since the panel member is fixedly held in the form of being suspended by the wire rope,
Further, it is necessary to fix the panel member to the support column with the tightening bolt. However, in the windbreak snow fence of the present embodiment, the stopper as the holding means is provided on the guide rail, and the panel is fixedly held by directly engaging with the guide roller shaft of the panel, so that it is not necessary to attach the tightening bolt. .
Therefore, it is possible to omit the complicated work of removing and installing the bolts each time when deploying and storing, and improving the workability of deploying and storing the windbreak snow fence.

Further, in the conventional windbreak fence, the panel member is moved upward by pulling the wire rope directly connected to the panel member, and when the panel member reaches the predetermined height position, the wire rope It was necessary to construct a wire rope as a holding means that also serves as a panel elevating means such that the tip end is fixed and the panel member is held for each of the columns. However, in the windbreak snow fence of the present embodiment, the stopper as the holding means is provided on the guide rail, and the panel is unfolded because the panel is fixed and held by directly engaging the guide roller shaft of the panel. Then, the panel raising / lowering means is not necessary, and the structure of the fence is simplified.

In the present embodiment, the left and right columns are tiltable inward, but both columns may be tilted in the same direction. Further, in the present embodiment, the left and right columns are independently configured, but for example, the right column of a certain panel horizontal section and the left column of the panel horizontal section to the right of the panel are integrally configured to have an integrated configuration. It is also possible to adopt a configuration in which guide rails are provided on the front and back of each of the formed columns.

[0087]

As described above, according to the present invention, the wind-proof snow fence can be formed only by moving the panel member, which is stored below the columns between the columns, upward along the movement guide portion while the holding means is attached. When storing the windbreak snow fence, simply attach a weight to the holding means and move the panel member downward along the movement guide part while the holding means is attached. Since it is stored below, it can be deployed and stored by a very simple operation.

Further, when deploying and housing the windbreak snow fence, it is not necessary to have a person nearby to work, so that safety in work can be secured.

Since the pillar and the panel member are both housed in the housing formed by the gutter, there is an effect that the scenery around the road can be almost completely secured during the housing period.
