with
The delivery winding device 40 is rotatable by a rotating device 60 .

According to this, the sliding plate 21 constituting the sliding body 20 is in the shape of a long thin plate, and the cross section in the width direction is formed in an arc shape with a concave top, so that the sliding plate 21 can be stacked on the roof 101. It has uprightness that allows it to be drawn out in a straight line into the snow S, and flexibility that allows it to be rolled up when returning to a straight line after the snow S is slid down.

Therefore, the sliding body 20 provided with the sliding plate 21 can enter the snow S piled on the roof 101 in the delivery direction and slide the snow S on the sliding body 20 to the outside of the roof.

Further, the feeding winding device 40 is made rotatable by the rotating device 60, so that the sliding body 20 is fed out from the feeding winding device 40 to lower the snow S to the outside of the roof 101. Then, the rotating device 60 is rotated in parallel with the roof surface 102 with the direction orthogonal to the roof surface 102 as the rotation axis, and the sliding body 20 is let out to lower the snow S to the outside of the roof 101 and wind it up. The snow S piled up on the entire roof can be gradually lowered to the outside of the roof 101 by repeatedly letting it return to the delivery winding device 40 .

Therefore, by constructing only the sliding body 20, the delivery winding device 40, and the rotating device 60, the amount of members used can be reduced, so that the snow removal device can be lightened and compact.

In addition, snow can be removed only by the delivery winding device 40 without other support members such as guide rails, which leads to a compact snow removal device.

Also, the slide body 20 is formed of one slide plate 21 .

Since the sliding body 20 is formed in this manner, the snow S can be slid off the roof.

A cutting portion 22 is provided on the upper surface side of the tip portion 21a of the slide plate 21 so as to extend above the slide plate 21 and cut the snow S accumulated on the roof 101 at least in the thickness direction.

According to this, when the sliding plate 21 enters the snow S accumulated on the roof 101, the snow S accumulated on the roof 101 is cut by the cutting part 22, so that the snow S can be slid off the roof 101. - 特許庁contribute.

More specifically, the snow S continues to be cut downward while being cut into a substantially rectangular cross section by the sliding plate 21 and the U-shaped cutting portion 22 . In other words, the snow S that has no lower side surface, so to speak, has a block-like shape and extends downward, but until the tip of the sliding body 20 reaches the eaves 109, it is below the tip of the sliding body 20. is not cut and remains connected to the surrounding snow S, so the snow S does not slide down. 101 slides out.

Similarly, when the sliding bodies 20A, 20B, 20C, and 20D are extended from the upper end of the roof 101 to the lower end, the snow S slides off the roof 101 at once in a row like a tokoroten. .

Equipped with a snow sensor SS as a detection means for detecting the amount of snow on the roof 101,
When the snow sensor SS detects a predetermined amount of snow, the controller unit CU
After the sliding body 20 is paid out from the pay-out and take-up device 40, it is taken up, and after the rotation device 60 performs a predetermined operation corresponding to the action of the pay-out and take-up device 40, it is stopped.

According to this, it is possible to automatically remove the snow without human intervention.

Further, the feeding and winding device 40, which is disposed on the side of the peripheral edge portion 105 of the roof 101, is rotatable by a rotating device 60,
The rotating device 60 can rotate the feeding and winding device 40 about a rotation axis in a direction orthogonal to the roof surface 102,
The sliding body 20 can be drawn out and wound up parallel to the roof surface 102.例文帳に追加

When the snow removal device 10 is arranged on the side of the peripheral edge portion 105 of the roof 101 such as the eaves 109 and the verge 121, even with such a configuration, the snow S accumulated on the roof 101 is gradually removed. Furthermore, it is possible to set the side on which the snow S is not desired to slide down, depending on the arrangement position of the delivery winding device 40 .

Further, the feeding and winding device 40, which is disposed on the ridge 103 side, is rotatable by a rotating device 60,
The rotating device 60 can rotate the feeding and winding device 40 with a rotation axis in a direction orthogonal to the roof surface 102,
The sliding body 20 can be pulled out and wound up parallel to the roof surface 102.例文帳に追加

When the snow removal device 10 is arranged on the ridge 103 side, even with such a configuration, the snow S accumulated on the roof 101 is removed little by little.

In addition, at the position where the sliding body 20 is extended from the roof 101, there is a contact bending portion 113 that contacts the sliding body 20 and bends the sliding body 20, so that when the sliding body 20 is extended, the roof 101 is formed. Correspondingly, a conversion member 110 is provided for converting the direction of unrolling of the sliding body 20 and changing the winding direction to the direction opposite to the direction of unrolling the sliding body 20 when winding the sliding body 20. - 特許庁.

According to this, since it becomes possible to correspond to the shape of the roof 101 by the converting member 110, it is possible to correspond to various kinds of roofs 101.

Further, the rotating device 60 rotates the feeding and winding device 40 about the direction orthogonal to the roof surface 102 as the rotation axis,
A first state in which the sliding body 20 can be reeled out and wound up above one roof surface 102a sandwiching the ridge 103, and a sliding take-up device 40 above the other roof surface 102b sandwiching the ridge 103. It has a state changing mechanism 85 capable of changing between a second state in which the body 20 can be drawn out and wound up.

With such a configuration, the two roof surfaces 102 sandwiching the ridge 103 can be cleared by one snow removing device 10. - 特許庁

Further, the sliding body 20 is extended upward with a space from the roof surface 102, and does not drop all the snow S accumulated on the roof 101.例文帳に追加Then, the sliding body 20 removes the snow S remaining on the roof 101 after a while.

Even if the snow S remaining on the roof 101 is reduced in height and becomes snow, when the snow S newly piled up on the snow S is taken down after the passage of time, the sliding body 20 will be replaced with new snow. Since it advances through the snow S, there is no problem in extending and winding up the sliding body 20. - 特許庁In other words, it can be said that the snow removing device 10 utilizes the fact that all the snow S accumulated on the roof 101 is not removed.

The sliding plate 21 shown in FIG. 44(f) can be formed upside down or right and left reversed.

As shown in FIG. 44(g), the slide plate 21 has a wavy central portion and linear ends at both ends in the lateral direction of the slide plate 21. is bent so that the left end extends obliquely downward and the right end extends obliquely upward. The sliding plate 21 of FIG. 44(e) can also be formed in a shape inverted upside down.

As shown in FIG. 44(h), the slide plate 21 has a wavy central portion and linear ends at both ends in the lateral direction of the slide plate 21. are bent, and both ends are formed to extend obliquely upward. The sliding plate 21 of FIG. 44(h) can also be formed in a shape inverted upside down.

The sliding plate 21 has uprightness that allows it to be drawn out in a straight line into the snow piled up on the roof, and flexibility that allows it to be rolled up when returning to a straight line after sliding down the snow S. For example, it is not limited to the above modification.

The same applies to the slide plates 21A, 21B, 21C, 21D, 21E, 21F, 21G, and 21H.

Also, the boundary portion between the central portion and the both end portions of the sliding plate can be applied either curved or bent.

Even if the sliding plate is formed in this way, it is possible to reduce the weight and make the snow removing device compact.
