Description

[Detailed description of the invention] Purpose of the invention (industrial application field) The invention is designed to automatically remove snow that has fallen on roofs, eaves, and other places that slope with a normal slope or have a gentle slope. The present invention relates to an air mat for snow removal that eliminates the need for manual snow removal work.

(Conventional technology) In areas with heavy snowfall, especially in areas with heavy snowfall, houses may collapse because roofs cannot withstand the weight of snow that exceeds the allowable limit, and people may be injured due to the unexpected fall of accumulated snow. Accidents can occur, so snow removal from roofs, etc. is essential.

Conventionally, there is no special method for removing snow from roofs, but for example, roofs have been made to have steep slopes to improve the sliding of snow to prevent snow from accumulating as much as possible. In addition, attempts have been made to prevent snow from accumulating on roofs using sprinklers, a well-known means of removing snow from roads and railroad tracks, but most households climb onto roofs and use human-force tactics to remove snow.

(Problems with conventional technology) However, even if the roof is steeply sloped,
There is a limit to the angle of inclination, and snow accumulation cannot be completely prevented.

In addition, although sprinkler-type methods improve efficiency, they require a large amount of hot water, increase equipment and maintenance costs, and also require sufficient drainage, as snow melted by hot water freezes as the temperature drops. In some cases, it was not possible to function satisfactorily in ordinary houses without such facilities.

This invention was devised in view of the above circumstances.
A wave motion caused by the supply and exhaust of compressed air is induced by the pine, and this wave motion can be used to remove snow from the roof. Moreover, it is a simple and highly safe snow removal method that does not require complicated mechanisms or electrical equipment. The purpose is to provide air mats.

Structure of the invention (means for solving the problem) In order to solve the above problem, the present invention uses a plurality of independent pumps that repeatedly expand and contract by repeatedly supplying and discharging compressed air sent from a pump. Consisting of rectangular air sacs, air sacs that are adjacent to each other in the short direction of each air sac are partially overlapped along the lengthwise edge of each air sac to form a quadrilateral shape as a whole. The outer peripheral surface of the pine body is covered with a sheet body formed by joining a front sheet and a back sheet, and this front sheet is made of a material that has great flexibility and is easy to slip on snow. be.

(Function) The air mat for snow removal of the present invention is installed on a sloping roof, and supplies and discharges air at the required pressure to all air sacs, and by supplying and exhausting compressed air, each air sac is The cells are forced to expand and contract in order, creating a wave motion. First, when the air sac at the bottom of the slope is inflated, the snow accumulated on the pine body where the air sac is located is lifted, and the snow in that area becomes unstable and slides down. Subsequently, when air is expelled from the air sac, this air sac contracts, but the next air sac that overlaps with the air sac starts to expand, and the air sac starts to expand on the pine where this air sac is located. Accumulated snow is similarly lifted and slides down along the slope of the roof, etc. In this way,
By sequentially moving the expansion and contraction of each air sac upward and causing wave motion to the pine body, the snow accumulation on the pine will be
All snow is removed.

The above air sacs can be expanded and contracted frequently depending on snowfall conditions, or at predetermined intervals, for example, all the air sacs can be expanded and contracted once every hour to constantly remove snow. It is possible to maintain the roof in the same condition as when it was installed. Note that the expansion and contraction of the air sac does not necessarily have to start from the bottom.

(Example) An example of the present invention will be described below based on the drawings.

FIG. 1 is a partial rear view of an embodiment of the present invention with some parts omitted, and FIG.
FIG. 3 is a cross-sectional view taken along line A.

In the figure, 1 is the mat main body, 2A to 2L are each air sac making up the mat main body 1, and 3 is each air sac 2.
A socket part 4 for repeatedly supplying and discharging compressed air into the interior of A to 2L has a plug at its tip that can be detachably connected to the socket part 3, and is connected to a pressurizing pump (not shown) as a compressed air supply source. This is the supply/exhaust tube that is connected. Although omitted in both figures, in this embodiment, the mat main body 1 shown in both figures is
Similarly, the mat main body 1 installed on the opposite side of the roof is formed symmetrically across the connecting part 1a, and is configured so that the entire roof can be completely covered with the air mat. has been done.

Each of the air sacs 2A to 2L is made of a material that is non-breathable, waterproof, and has a smooth surface, and has a predetermined width W and a length corresponding to the width of the roof.
A quadrilateral mat main body 1 having a size large enough to cover one side of the sloping roof is constructed by overlapping and connecting parts S of separate air cells adjacent to each other in the direction (short side direction) in a chain. There is. Note that the ratio between the overlapping portion S and the width W of the air sac is unfavorable because if the overlapping portion S is larger than 1/2 of the width W, the waves of expansion and contraction of the air sac 2 will become too small. It is preferable to set the overlapping portion S to about 1/3 to 1/4 of the width W.

It should be noted that the size and shape of general houses vary, and the size and shape of the roof usually vary accordingly, so it is not possible to specify the size of the mat main body 1. Therefore, in the normal case,
A plurality of mat bodies 1 are used for one side of the roof and are installed so as to cover the entire roof.

Further, in the figure, 5 is a waterproof top sheet that covers the air sacs 2A to 2L, and 6 is a waterproof back sheet that also covers the air sacs 2A to 2L.
The four sides of the mat body 1 are joined together to form a sheet body 8, and this sheet body 8 is covered with the outer peripheral surface of the mat body 1 to form an outer skin. In addition, front sheet 5
It is preferable that the material is highly flexible and makes snow slippery. In addition, it is desirable that the back sheet 6 has flexibility so as to fit the roof tiles.
It is best to use something that is not slippery. 7 is a mounting hole for installing the mat main body 1 on the roof.

In addition, instead of the air sacs 2A to 2L of this example in which the air sacs are partially overlapped in a chain manner, the air sacs may be arranged in a row without overlapping to form a quadrilateral configuration.

FIG. 3 is a partial side view schematically showing an embodiment in which the mat main body 1 is integrally laid and formed on the upper surface of a sloped roof member, and FIG.
Figure B shows the pattern when A is in an expanded state, and the figure b shows the air sac 2A above it when the lowest air sac 2A is retracted.
This shows the pattern of B expanded. In the figure, 8 is a roof member, and in this example, the above-mentioned air mat is laid all over the upper surface of the roof member 8 to cover the roof. It goes without saying that the top surface of the air mat is made of a material that makes snow slippery.

The air supply/exhaust tube 4 connected to each air bladder 2A to 2L is fixed to the roof member 8, and is connected to the socket portion 3 of each air bladder 2A to 2L via an air branch pipe (not shown). After each 2
It is configured to supply and discharge compressed air to A to 2L.

In addition, in Figure 3 a and b, 9 is the snow layer,
10 is a snowpack that has been released from the roof by the wave motion of the pine tree and is about to fall to the ground.

Further, the air mat may be laid and formed during roof construction, but it may also be configured to be installed just before the snowfall season.

Next, the effects of the above embodiment will be explained mainly in FIGS. 3a and 3b.
The explanation will be based on.

When compressed air is sequentially supplied and discharged to air bladders 2A to 2L that partially overlap in a chain in the short side direction, these air bladders 2A to 2L alternately expand and contract to perform wave motion. . Therefore, when the air mat of this embodiment is fixed to a sloping roof and this undulating motion is repeated, the snow on the roof that has fallen on the mat body 1 will be lifted up when the air sac 2A expands. The situation becomes unstable, and the snow in that area peels off from the snow layer 9, becomes a snow mass 10, and easily slides off the roof. After that, air is removed from the previously inflated air sac 2A, and the same air sac 2A is deflated, and another air sac 2B located next to it is inflated. The snow located at is similarly lifted and slides off the roof as a snow mass 10. In this way, each air cell 2
When the expansion and contraction of A to 2L are performed alternately, the snow that has fallen on the pine main body 1 is always kept in an unstable state, so that it becomes easy to slide down on the pine. This expansion and contraction movement of the air sacs 2A to 2L is performed at different intervals depending on the state of snowfall. When there is a lot of snowfall, the intervals are shortened and the air bladders 2L are expanded and contracted frequently, and when the amount of snowfall is low, for example, for one hour. By repeating this at regular intervals, the roof will always return to a cleared state.

Effects of the invention As is clear from the above explanation, according to the invention, the wave motion caused by the supply and exhaust of compressed air makes the snow accumulated on the roof unstable, making it easier to slide down, and making it appear as if it were on the surface. Since the snow can be slid down in a manner similar to generating an avalanche, snow can be removed reliably. In addition, since there is no need for complicated mechanisms or hot water spraying, it can be equipped with highly safe equipment at low cost, and has good durability against rain and snow. Furthermore, according to the present invention, the roof itself has a snow removal function, so manual snow removal is completely unnecessary.

In particular, since the air sacs that are adjacent to each other in the short side direction of each air sac are partially overlapped, when the adjacent air sacs expand one after another, the snowy part becomes slippery and easy to fall. In addition, since the outer circumferential surface of the mat body is coated with a sheet body consisting of a front sheet and a back sheet made of a material that has great flexibility and is easy for snow to slip on, it has the effect of being able to smoothly slide off accumulated snow.
