Description

  The present invention relates to a snow removal tool that can efficiently and safely remove snow from a roof.

  In areas where there is a lot of snow, there is a case where snow exceeding the endurance amount accumulates on the roof of the building. Under such circumstances, an operator climbs on the roof and performs snow removal using a snowplow such as a scoop. In addition to heavy labor, this snow-removing operation is slippery and dangerous. In particular, work near the tip of the roof is difficult to understand because the position of the tip of the roof is covered with snow, and it is easy to step off and the risk of slipping increases.

Here, a snow removal tool that can safely remove snow without climbing the roof has been proposed (see, for example, Patent Document 1).
This snow removal tool is formed by providing a long handle on a snow shovel portion composed of a base plate to which a sheet is attached and a side cutter. According to this snow removal tool, the snow cut off by the base plate and the side cutter can be slid down on the sheet, so that the snow on the roof can be removed while on the ground.

DESCRIPTION OF EMBODIMENTS Embodiments embodying a snow removal tool according to the present invention will be described below with reference to the drawings.
[Embodiment 1]
As shown in FIG. 1, the snow removal tool 1 includes a long handle 40 and a snow shovel 30 fixed to the tip of the long handle 40.

The snow shovel 30 is composed of a snow cutting member 10 and a plate-like member 20.
The snow cutting member 10 is a member that is inserted into snow and cuts snow, and includes a horizontal plate 11 and a pair of vertical plates 15 and 15 erected on both ends of the horizontal plate 11. The material of the horizontal plate and the vertical plate is not particularly limited, but is preferably made of metal in order to maintain strength. Moreover, although the thickness does not have limitation in particular, it is preferable that it is 2.5-3.5 mm, and it is still more preferable that it is 2.8-3.2 mm. If it is less than 2.5 mm, it is easy to deform when inserted into snow, and if it exceeds 3.5 mm, resistance to snow becomes large and it becomes difficult to insert.
On the upper surface of the horizontal plate 11, a pair of standing pieces 50 and 50 for fixing the tip of the handle 40 is provided. In the standing pieces 50, 50, two through holes 50a, 50a are formed in the horizontal direction, and one through hole 50b is formed in the upper part in the distal direction. As shown in FIG. 5A, the handle 40 is fixed to the snow cutting member 10 by fixing the through hole 40 h drilled in the handle 40 and the through hole 50 a with the fixing tool 70.

As for the horizontal plate 11 and / or the vertical plate 15, as shown to FIG. 2 (a), (b), it is preferable that the front end side is gradually formed thinly toward the direction which cut | disconnects snow. By having the inclined surfaces 11a and 15a, resistance to snow is reduced and insertion becomes easy.
The ratio of the thickness S of the tip portion to the plate thickness T is not particularly limited, but is preferably T: S = 3: 2.5 to 1.5. For example, T = 3 mm and S = 2 mm.

  A pair of slide members 60 are provided on the bottom of the snow cutting member 10 so as to face the vertical plate 15. By doing so, since the slide member 60 slides with respect to the roof, the horizontal plate 11 and the fixing member for the horizontal plate are not in direct contact with the roof, and can be easily inserted into snow and have excellent workability. .

  The tip of the lower part of the slide member 60 and the upper part of the standing piece 50 are formed in a round shape. By doing so, resistance to snow can be further reduced when the snow cutting member 10 is inserted into the snow.

The plate-like member 20 is a member that has one end fixed to the horizontal plate 11 and slides down the snow cut by the snow cutting member 10, and has a bellows shape that can be folded in a direction perpendicular to the direction of cutting the snow. Is formed. As shown in FIG. 1, the plate-like member 20 is composed of small plate-like bodies 21, 22, 23, and 24, and is formed to be foldable in a bellows shape by mountain fold portions 20 a and 20 c and valley fold portions 20 b. Yes.
The material of the plate member is not particularly limited, but is preferably a light and hard member. For example, plastic cardboard can be suitably used.
By making the plate-like member into a hard bellows shape, the effect of sliding off snow is much higher than that of the soft sheet material. That is, since it is bellows-like, when inserting into snow on the roof, the bellows mountain fold part and valley fold part come into contact with protrusions such as the roof tip part and snow on the roof, so that the plate-like member Sways up and down, and the vibration increases the force to slide snow. Furthermore, unlike a soft sheet material, it does not shift, overlap or wrap around in the lateral direction.

The handle 40 is connected by sequentially inserting cylindrical members 41, 42, and 43, and is fixed by a fixing tool.
The handle is not limited to this configuration, and may be a single cylindrical member or a solid rod-like member. Moreover, as shown in FIG. 3, the structure which can be slidably inserted and fixed to the inside of the cylindrical member 40b by the cylindrical member 40a by the lever 45 may be sufficient.

(Production)
The snow removal tool 1 can be produced as follows, for example. As shown in FIG.
The vertical plate material 15A, the standing piece material 50A, the horizontal plate / slide member material 11A, the plate member 20, and the plate member fixing plate 11B are fixed by a fixing tool (for example, a bolt nut, a wing nut, etc., the same shall apply hereinafter). . As the fixing tool, a wing nut is particularly preferable because it can be attached and detached with only fingers without using a tool. In this way, the snow shovel 30 is formed.
Next, if the handle 40 is fixed to the standing piece material 50A with a fixing tool, the snow removal tool 1 is completed.
However, this manufacturing method is an example, and the manufacturing method can be changed as appropriate.
