Description

  The present invention relates to a roof snow removal device.

In heavy snowfall, the snow on the roof is climbed on the roof where people have accumulated snow and dropped under the eaves using scoops or snow dumpers. However, the snow-removing work by human power is a heavy labor and a work on a sloped roof, so there is a risk of falling. Especially in the heavy snowfall area, there are many elderly people, and it was difficult to carry out the snowfall by climbing the roof.

For this reason, various snow removal devices for roofs using machines have been proposed. For example, they are arranged at intervals in an inclination direction from a high position to a low position of the roof, and are perpendicular to the inclination direction and parallel to the roof. A sheet material comprising a pair of end rollers having a rotation axis and a sheet material wound endlessly around the pair of end rollers along the inclined direction, and the weight of snow on the sheet material covering the roof A snow unloading device (Patent Document 1) is proposed in which the sheet material is moved by a load received from snow and the snow on the sheet is dropped.

However, the mechanical snow unloading device with multiple belt conveyors on the roof is complicated in structure, expensive in equipment, heavy on the roof, cumbersome maintenance work, roof repair and painting work, etc. It is not assumed that there is a risk that the snow on the seat will fall unexpectedly.

For this reason, as a simple device, the sheet is hung from the top of the roof to near the ground under the eaves, the sheet is pulled down by hand to drop the snow on the sheet, and then the rope connected to the top of the sheet is pulled. A snow removal device (Patent Document 2) that returns a sheet onto a roof has also been proposed. However, although this snow removal device is inexpensive, there is a risk that the snow piled up on the seat will fall unexpectedly. In addition, the seat hangs near the ground and the window is blocked, so the room is dark and it is necessary to dismantle it in the spring.

Therefore, under the present circumstances, climbing the roof while still in danger, and snow removal work by manpower using scoops and snow dumpers is being carried out, and there is a demand for the development of a device that can easily and safely remove snow by elderly people and women. It was.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 denotes a roof snow lowering device. A plate member 2 formed of a flexible material having elasticity such as vinyl chloride is vertically and horizontally combined to form a plane rectangular frame 3, and a net 4 is formed thereon. The rising portion 5 is formed on the upper side (left side in FIG. 1) arranged on the roof ridge side of the frame body 3, and the wires 6 are connected to both sides thereof, and one is formed below the upper portion. A ring-shaped handle 7 is attached to the other end of the wire 6 on the eaves 12 side (the right side in FIG. 1) of the roof 10.

The stitch size of the net 4 is preferably 10 to 50 mm, for example, the width of the frame 3 is 1 to 2 m, and the length is the length from the ridge 11 to the eaves 12 of the inclined roof 10 as shown in FIG. To form. In this case, if the size of the stitch is less than 10 mm, the snow stop effect is small, and if it exceeds 50 mm, the snow passes through the stitch and the entrainment effect is small. The lower side of the roof snow lowering device 1 is fixed to the eaves 12 of the roof 10 with screws, and the upper side of the ridge 11 is left free. In addition, since the pipe 13 is attached along the lateral direction of the eaves 12, the wire 6 comes into contact with the pipe 13 and hangs over the net 4 and the gutter 17.

When the wire 6 is pulled as shown in FIG. 3, the roof snow lowering device having the above-described structure is constructed such that the frame 3 made of an elastic flexible material is curved by pulling up the free standing portion 5. Move away from 10. When the wire 6 is released, the wire 6 returns to a flat shape due to elasticity and is laid on the roof 10.

In this state, in the winter, as shown in FIG. 4, as shown in FIG. 4, snow 14 is piled up on the net 4 of the roof snow lowering device 1, but since the bottom of the snow 14 bites into the stitches of the net 4, there is a snow stop function. , It can be prevented from unexpectedly falling from the roof 10. When the snow is 30 to 50 cm, the lower hook 16 is hooked on the handle 7 at the tip of the wire 6 hanging from the eaves 12 and pulled downward.

When the wire 6 attached to the tip of the roof snow lowering device 1 is pulled, the free rising portion 5 is pulled up as shown in FIG. 5 and the upper side of the frame 3 is curved, so that the snow 14 is rolled up in a snowman shape. While rolling over the net 4, it moves to the eaves 12 side and falls as a lump onto the ground from here. Since the wire 6 can be pulled away from the eaves 12, it is safe against the lump of snow 14 falling from the eaves 12.

In this way, it is possible to easily carry out snow removal over a wide area by sequentially pulling the wires 6 of the plurality of roof snow removal devices 1 attached to the roof 10. With the roof 10 having an inclination of 10 degrees and an area of 20 square meters and three roof snow lowering devices 1 arranged side by side, when the snow cover reaches 50 cm, the roof snow lowering device 1 is operated in sequence, so that three wire pulling operations are performed. The snow removal of the roof 10 can be completed in about 15 minutes. Further, when the wire 6 is released, the frame 3 is made of a flexible material having elasticity, so that it returns to a flat shape due to its elasticity. Moreover, since the pipe 13 is attached along the eaves tip 12, the wire 6 can be pulled smoothly on this while preventing damage to the net 4 and the rain gutter 17.

In addition, a rising portion 5 is formed at the tip of the roof snow lowering device 1, and a wire 6 is connected to the tip of the roof snow-removing device 1, and the inclination of the roof 10 is also used. In addition, the snow can be removed in a short time. Moreover, if the snow is removed frequently when the amount of snow reaches about 30 cm, a large amount of snow is not dropped at once, and it is easy to clean up the snow.

Further, since the roof snow removal device 1 is simple and light in weight, it can be installed throughout the year without placing a burden on the roof 10, and the roof snow removal device 1 can be lifted away from the roof 10 by pulling the wire 6. Therefore, the roof 10 can be easily repaired and painted. Moreover, when the coating of the roof 10 is brown, for example, if the frame 3 and the net 4 are also colored brown, the landscape of the roof 10 is not impaired.

In the above description, the case where the pulling hook 16 is held in hand and the wire 6 is pulled manually has been described. However, the wire 6 may be pulled manually or using an electric winch.

FIGS. 6 to 8 show another embodiment of the present invention, in which pulleys 18 are attached to the left and right of the rising portion 5, and the tips of the wires 6a and 6b are fixed to the left and right of the frame 3 on the eaves 12 side. The middle part is folded back through the pulley 18, and a ring-shaped handle 7 is attached to the eaves tip 12 side of the wire 6 with a single piece below the pulley 18.

Further, the wire 6 below the pulley 18 is provided with an anti-roll-in stopper 19, and when this reaches the pulley 18, the length between the tips of the wires 6 a and 6 b on the eaves 12 side and the pulley 18 is not further shortened. It has become. Further, the eaves tip 12 side of the vertical plate member 2 of the roof snow lowering device 1 penetrates the net 4 and is fixed by an inverted L-shaped presser fitting 20 as shown in FIG.

As shown in FIG. 9, the roof snow lowering device 1 having the above configuration pulls up the wire 6, the rising portion 5 to which the pulley 18 is attached is pulled up, the upper side of the frame 3 is curved, and the snow 14 is wound up in the shape of a snowman. While rolling over the net 4, it moves to the eaves 12 side and drops from here to the ground. When the upper side is curved, the left and right wires 6a and 6b are also lifted, and the snow 14 accumulated thereon is cut into left and right parts, so that the snow 14 in the meantime can more easily fall.

Further, since the left and right wires 6a and 6b are provided with an anti-roll-in stopper 19, as shown in FIG. 9, when the wire reaches the pulley 18, it is not sent any further, and between the pulley 18 and the fixed portion on the eaves 12 side. Since the eaves 12 side is pressed by the presser fitting 20, the roof snow lowering device 1 entrains and moves the snow 14 downward while maintaining the state where the upper side is curved in an arc shape. Can be dropped under the eaves. In other words, if there is no entanglement prevention stopper 19 and presser fitting 20, the roof snow lowering device 1 may curl up to wrap the snow 14 as indicated by the phantom line, and the snow 14 may remain and not fall. Further, the pulley 18 attached to the rising portion 5 acts as a moving pulley because a load is applied to the rising portion 5 side, and the length for pulling the wire 6 is doubled, but the force for pulling the wire 6 is half.

FIG. 10 shows another embodiment of the present invention, in which the eaves 12 side of the longitudinal plate member 2 constituting the frame body 3 is separated and is connected rotatably by a hinge 21. . This is because when the roof 10 is repaired or painted, the roof 10 is exposed by folding the upper part of the roof snow removal device 1 at the hinge 21 or by removing the hinge 21.

FIG. 11 shows another embodiment of the present invention, which is attached to the valley roof 10 where the snow 14 accumulates most. This is provided with two roof snow lowering devices 1, and plate members 2 on the side surfaces in the longitudinal direction of the opposing frame 3 are connected by a hinge 21 so as to be freely opened and closed. When the snow 14 accumulates on the roof snow lowering device 1, when both the wires 6 are pulled by holding the handle 7 with both hands, the upper side is curved as described above, and the snow 14 can be efficiently dropped.

The shape of the frame 3 may be a planar square shape. The roof snow removal device 1 of the present invention can be installed not only on a tin roof or a tile roof, but also on a roof of a car pox or a solar panel. In particular, it is effective for snow-stopping a solar panel in which a large amount of snow 14 falls at a distance. Further, instead of the pulley 18, a ring through which the wire 6 passes may be attached. Moreover, although the case where the wire 6 was used was shown in the above description, the present invention is not limited to this, and a rope may be used. Further, the rising portion 5 may be integrally formed by bending the vertical plate 2 constituting the frame 3 upward. When not in use, the handle 7 hanging from the eaves 12 is hung on the steady hook so as not to generate a collision sound by shaking with the wind.
