Description

  It is an instrument that can efficiently and safely remove roof snow, etc., using the abbreviated name "snow sink" using the slope. A “snow sink” made up of two 1.8-meter corrugated plates made of thin, long, somewhat elastic metal, 4 meters of clothes-bars and 2 light and hard-to-break polycarbonate resin In particular, the fact that polycarbonate corrugated plates are particularly effective in snow flow is added.

  A pair of snow sinks is 4 meters in length, so even if the A and B locations are separated, the snow sink can also act as a bridge, allowing snow to flow from the A location to the B location. It is.

  It is possible to run in a straight direction, a zigzag direction, or a reverse direction in places where there is a step, by applying several snow sinks.

  When loading roof snow, etc. onto a truck, it is more efficient to concentrate the roof snow in one place, but it is easy to use the method (0003).

  In the case where the surrounding vacant land is wide when snowing the roof and it is not necessary to move the snow that has fallen to other places, it is possible to remove the snow evenly except for the necessary place of the house by the method of (0003).

For the so-called zigzag direction that changes direction from side to side, the tip of the snow flow of the clothes-drying bar attached to both sides of the snow sink (the tip of the 1.8-meter corrugated sheet overlap indicates which is the tip) is the same length If you make four sets, you can arrange the two sets so that the left is short, and the other two sets are short so that the snow flows efficiently.
Remark 1 (0006) seems to be difficult to understand by just explaining the words, so it will be explained later with a diagram.

Japanese Patent Laid-Open No. 2002-242399A (P2002-2423A) In order to draw snow into the runway with a snow removal device on the roof, the snow is drawn by the operating arm and guided to the slide guide using the slope of the roof and dropped to the ground. There is, however, a method of snow removal that can only be applied to fresh snow or the free-flowing snow quality of regions with extremely low temperatures. Even in the heavy snowfall area in Aomori Prefecture, the snow is usually removed once or twice a winter, and the house is built according to the amount of snow in the region. Unloading is unusual. I touched the snow unloading about twice a winter here, not only the snow falling of fresh snow, but the snow that had accumulated over and over several times became a little harder because the lower part of the snow was stuck. It seems to be a consultation that can not be attracted. In addition, even if the amount of snow thrown away in a cylindrical shape is somehow small, when a large amount of snow is thrown away, a phenomenon occurs in which the snow in the cylindrical shape is connected to the snow accumulated on the ground and the flow stops. The height of the roof of a normal house and the first floor is less than 2 meters, so the use of a cylindrical shape is unsuitable considering the fact that the height of snow on the ground is getting higher. Should be noticed.

Utility model No. 3043956 gazette It is an instrument that is reminiscent of a snow slide at first glance with an instrument combining a trapezoidal snow-falling tool body and a snow-sliding belt-like sheet. Since the trapezoidal snow-plow body is laid, it seems to be an instrument that has the disadvantage that it cannot be used more than one unit even when it is desired to work with two or more roofs that are long and have a long slope. The other is when using a cylindrical sheet from a trapezoidal shape, where the snow can be placed only on the trapezoidal shape, resulting in a narrow working range and when the cylindrical sheet is hung under the roof. However, it seems to be unsuitable for use in heavy snow areas because it involves the disadvantages of the patent example. In addition, what is common to the two documents is that a sheet is used as a component for snow sliding, but whether or not a member with better snow sliding was not selected. Although it is clear that a sheet that can be folded during summer is more convenient, it may be more important to consider the snow slide as the life of this tool.

As described in the above-mentioned “Patent Document 1” and “Utility Model 1”, the snow on the roof is not as close to the building as it is near the snow throwing shed in the scoop. Throwing away is a long work, and it is a hard work. In addition to this heavy labor, there are some that have been shunned due to the danger involved in high-altitude work.
At present, the snow dumper is raised on the roof to improve the efficiency of the work, but there is a problem whether there is any better way.
These can be summarized as the following issues.
1. Development of tools that can use slopes because ordinary roofs have a slope.
2. In modern times, many roofs with no slope are seen as snow-free roofs. However, in heavy snow areas, if the snowfall is 1 meter away, there is an earthquake, so it can be applied to snowfall on roofs with no slope. development of.
3. Development of tools that can be applied to roofs such as higher towers.
For the above 1, 2, and 3, use the same basic tools, and then develop a wide range of tools by adding accessories tailored to each roof.

Although it is the development of a device that flows snow using the height difference and the slope, two metal 4-meter clothes bar as described in the "Technical Field" and "Background Technology" sections. A pair of “snow sinks” made up of two 1.8-meter corrugated plates made of glass and polycarbonate resin has a snow sink of 3.5 meters and a width of 0.7 meters. It will be used as an instrument. If you prepare four sets of these "snow sinks", you can safely and well drop snow on the roof of a house that seems to be quite large. There are various structures even if it is a general house, and I would like to say that because it is possible to improve the work efficiency or the person who worked according to the characteristics of the structure.
1. The slope of the roof of the house after the war has become quite low due to architectural reasons. Even in such a low-slope roof snow, the polycarbonate resin corrugated plate can be sufficiently swept away by the slipperiness of the snow.
2. If the area of the roof is wide and long, such as a single-flow roof, it is possible to snow efficiently by using several sets of `` snow sinks '' arranged in a linear direction or zigzag direction depending on the position of snow throwing away etc. .
3. In buildings with roofs on the first and second floors, there are two methods: snowing directly from the roof on the second floor to the ground and snowing via the roof on the first floor. There is also a method of lowering to the ground directly from the second floor roof via the first floor roof using a “snow sink”, which is related to the relationship between the roof structure and the snow removal location and the work efficiency. It will be decided by thinking.
4). In the case of a snow-free roof, there is no slope, so it can be guessed that there are many people who think that, but if you make a slope to the "snow sink" using an auxiliary tool, it will snow It becomes possible to flow snow and to make snowfall efficiently.
5. I think that it will usually ask professional workers to snowfall with a high roof like a tower, but these professional people will also be able to work more safely and efficiently if using "snow sinks" I think.

1. The principle is the use of snow sliding using the height difference.
2. This is the slipperiness of corrugated sheet refined with polycarbonate resin.
3. The effect of the parallel waves on the corrugated plates allows the snow bunks to flow accurately without changing the direction of the sink, so the direction change and zigzag flow accurately, improving work efficiency.
4). Even if the roof is flat (no-fall snow roof), it is possible to make the slope and shed snow by using a device such as an auxiliary tool.
5. If it is the length of one snow sink, it is possible to create a snow flow in the opposite direction by using a device such as an auxiliary tool.
If the above five things are combined and a snow sink is used, the range of application will be widened and the effect of the device will be demonstrated.

Perspective view of snow sink Perspective view of auxiliary tool for snow sink Flow prevention stick for snow sink

In the snow removal of the roof, you can not think of the idea that scoop or snow dumping is mainstream and use the slope of the roof to drop snow, or you can think about how it can be realized even if you notice it Maybe not. It's been a long time since I made and used this snow sliding device, and at one time I installed a snow sliding device temporarily on the road (of course, it is on the road so that passenger cars and trucks can pass under this There was a time when the roof snow was flushed to the vacant land (which was set at such a height), but it seems that everyone thought it was “great”, but no one imitated. It was something unrelated to us because it was the uncle of the invention.
After obtaining a patent for the snow leopard, we asked for a prior investigation at the Invention Church as to whether anyone in the country applied for the registration of this snow slide device with the Patent Office. There were two snow sink devices on the sheet. However, because the scale of the snow on the roof is small and impractical at the snow throwing part and the snow slides on the sheet were difficult, we decided to apply for registration as a utility model.
Once registered with the JPO, it will be introduced in the official gazette, so if you have many opportunities to touch the eyes and become on the market, you will notice and be interested in safe and efficient roof snow removal methods. I think that it will be useful for society if it can be used by the people who show it, and it can also be used by professional roof snow removal workers and people of snow removal volunteers in each municipality these days.

The house that is in contact with my house on the back side is the one who is now 100 years old, but has been living in an elderly home in the city with the care of her daughters and her husband since about seven years ago. From the time this person lived in his own house, he talked with him and his daughter and his wife, and in the case of snow removal in the winter and snowstorms, earthquakes, etc., I made a promise by contacting my daughter I was doing.
Since the conditions are wide, it is only necessary to drop the snow on the roof of the person around the house, and the snow on the roof of my house can also be dropped on this land (because it will melt in the spring) .
For this reason, roof snow at my home used to be shed on a public road by passing a “snow sink” on the public road. is.
Since the direction of the ridged roof ridge on the second floor of the next house is parallel to the public road that passes below, it is easier to use the slope snow on the public road side to the public road. Although it becomes work, the snow that falls on public roads must be carried that day, which leads to heavy labor.
In such a case, these four sets of “snow sinks” are very powerful. Only a little snow from the eaves on the public road side is dropped to the public road side, and most of the remaining snow flows backward using these four sets of `` snow sinks '' using auxiliary tools (the lower side of the slope is slightly less than the purlin) The higher the scoop, the higher the scoop will be, but there will be no subsequent work, so the work time will be shortened and physical strength will be consumed less. At this time, two “snow sinks” are used on the roof of the first floor, this is used almost in a fixed state, one on the second floor is a little fixed, and the other one is in full operation. It has been.
Because it is a work by one person, when working in the usual way, it takes a few days to complete a place that takes several days.

My house is about 8 meters x 12 meters with a single-flow roof. In order to let the snow on this roof flow to the house on the adjacent land, four sets of "snow sinks" are connected in a combination of a straight direction and a right turn direction. It's snowing down with snow.
Although it is a fairly long roof, it is not possible to arrange four pieces at a time, but gradually increase the number of sheets by working from a low position, eventually use all four sheets, and remove one by one from a higher position and finally It ends with one piece. At this lowest position, there is no difference in height, so you can use the auxiliary tool to make the slope.
Putting snow into the snow sink is right next to the equipment, so there is little exhaustion of physical strength, and work is done in the roof except for the first eaves part, so there is less danger and safe work can be continued .
However, if it is normal, don't forget to wear a “lifeline” because of earthquakes.

1. Snow drift equipment can be quite expensive and may be a storage location, so private ownership may be somewhat impossible, but once prepared, it can be used for several years, so prepare it at the local assembly etc. and share it If you do, will you help each other?
2. For professionals, it would be helpful for companies to save time, reduce labor, and ensure safety, and to improve work efficiency.
3. In modern times, the number of late elderly people living alone has increased, and it is expected that the number of households will continue to increase in the future, and many municipalities are recruiting volunteers for volunteers and other government officials to remove snow. It is supposed to be.
In consideration of the fact that snow works continue every year in each municipality, in addition to shovels, snow spats, snow dumpers, etc., snow drifting equipment is purchased on a budget, and people who are more in trouble will be able to improve safety and work efficiency. It seems to be possible to save.
