Description

  The present invention relates to a snow removal tool capable of rotating a snow removal board left and right by an operator's operation.

  Conventionally, various snow removal tools have been used. However, as shown in the present invention, no snow removal plate has a rotating function.

In snowfall areas, winter snow removal is essential.
At the time of snow removal, manual work using a snow removal tool is frequently used.
As a snow removal tool used in this case, a scoop has been used for a long time, and a snow removal tool having a snow removal portion shallower than the scoop, a hand-held snow removal tool having a large bucket portion (commonly known as a snow dumper), a snow russell that pushes snow, etc. It is often used.
Snow Russell is a relatively new product compared to other snow removal tools, and it has a curved plate as a snow removal part and a handle perpendicular to the curved plate. Press to use.
This snow raschel has the advantage that the snow on the road can be moved cleanly because the angle between the lower edge of the curved snow removal board and the road surface is close to a right angle compared to other snow removal tools. It is easy to stack in the direction of travel, and if it moves a little, it becomes difficult to move forward due to snow resistance, so throw this snow russell on the snow removal board and throw it away to the other side to empty it again. There was a problem that needed to repeat the forward work.
In view of the above, the present invention tilts the snow removal board in either the left or right direction in a plan view by a simple operation of the operator, and thus the snow stacked in the traveling direction of the snow removal board is moved in the inclined direction of the snow removal board. It was developed for the purpose of providing a new and useful snow removal tool that allows snow removal work far longer than conventional products.

The present invention has the following configuration as means for solving the problems.
That is, in a snow removing tool having a snow removing plate and a handle having a circular cross section attached to the snow removing plate, a handle having an upward angle at an obtuse bent portion of the handle is provided on the snow removing plate, and the handle end is provided at the lower portion of the snow removing plate. A handle is provided so as to be rotatable with respect to the snow removal plate by being rotatably inserted into a hole provided in the connecting portion. This invention is a snow removal board rotation type snow removal tool which consists of the above structure.

According to the present invention, since it is possible to swing the left and right in a plan view of the snow removal plate with respect to the handle, it is possible to escape snow that exceeds the snow removal plate capacity in a tilted direction, and to a conventional snow removal tool that was only parallel straight traveling In comparison, it is possible to obtain a useful tool that can increase the travel distance.
In addition, it is possible to use the same as the conventional product by releasing the swing by inserting it into the rotating part such as a pin and fixing the handle vertically to the snow removal board. By doing so, the snow removal tool can be separated from the snow removal plate and can be conveniently stored.

Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes a snow removal plate, which is a rectangular shape in plan view made of synthetic resin, and has a concave shape toward the center in a curved shape that is concave upward in front view. A connecting portion 2 is integrally formed in the middle of the bottom of the snow removing plate. Reference numeral 3 denotes a handle, which is a synthetic resin tube having an appropriate length, one end of which is inserted and held in the connecting portion via a connecting tube which will be described later, and the gripping portion 4 is fixed to the other end. Reference numeral 5 denotes a connecting pipe made of a metal pipe as a part of the handle, which is bent at an obtuse angle in a front view. One end of the connecting pipe is inserted and fixed to the handle, and the other end is inserted and held in a loosely fitted state in the connecting portion.

As shown in FIG. 5, the connecting portion 2 is formed of a synthetic resin tube body, and has a main reinforcing plate 6 and a horizontal reinforcing plate 7, and is integrally formed at the lower portion of the snow removal plate. As shown in FIG. 8, the tube portion of the connection portion is provided with a connection tube insertion portion 8 having a hole having an appropriate length, and has a step portion 9 having a slightly smaller diameter. As shown in FIG. 8, the connecting pipe has a step portion 10 having a slightly larger diameter, and the distance from the step portion to the end of the connecting tube is substantially the same as the length of the connecting tube insertion portion.
Reference numeral 11 denotes a fixed ring, which is a washer-shaped metal ring, the outer diameter of which coincides with the connecting portion, and the inner diameter thereof is close to the outer diameter of the connecting pipe. Further, the fixed ring is provided with holes equally spaced, and female screws are similarly engraved on the end face of the connecting portion. Therefore, as shown in FIG. 8, this fixed ring is screwed to the end face of the connecting portion with screws 12, and the large diameter portion of the connecting pipe is located between the step portion 9 and the fixed ring, and its axial direction The movement of is restricted while being able to rotate.
Reference numeral 13 denotes an insertion hole penetrating the connecting portion and the connecting pipe, and reference numeral 14 denotes a butterfly bolt housing hole which is drilled through the handle. 15 is a commercially available butterfly bolt, and 16 is a wing nut.

Next, the use of the present invention will be described. First, as shown in FIGS. 5 and 6, the wing bolt and wing nut inserted and fixed in the insertion hole are removed, and the wing bolt storage hole of the handle is inserted and held.
In this state, the handle is rotatable with respect to the snow removal plate.
When the handle part of the handle is twisted to the lower right, the handle rotates, and the connecting pipe is swung forward and tilted to the right, so that the snow removal board can be tilted as shown in FIG. If the snow removal work continues, that is, if you move forward while holding the handle, the snow piles up on the snow removal board.Since this part of the snow will eventually be pushed to the right due to this inclination, the snow removal board will continue straight while keeping a certain amount of snow. can do. When the gripping part is twisted to the lower left, the snow removal board tilts to the left contrary to the above, and the same operation can be performed. If you want to go straight in the conventional system, remove the wing bolt and wing nut from the handle and fasten them in the insertion hole of the connecting part as shown in Fig. 10. It is possible to remove snow in a straight line while keeping the handle and snow removal board vertical.

Although the present invention has been described above, the present invention has a feature in which the snow removal board can swing left and right, and can perform snow escape in the case of forward snow removal, which is impossible with the conventional product. Long distance snow removal is possible.
In the example, the connecting pipe bent into the straight tubular handle is inserted and fixed and integrated, but it may be fixed by screwing or the like. Also, instead of the wing bolt and wing nut as the fixing means, as shown by the phantom line in FIG. 8, the wing nut is combined with the ring and the male screw integrated, and inserted into the insertion hole from above and fixed. It is good. Further, the illustrated snow removal plate structure is an example of implementation, and may be another structure that satisfies the purpose, and the bending angle of the connection pipe can be appropriately selected and designed according to the use situation. In the example, the pivotable holding structure of the connecting pipe with respect to the connecting portion is an example, and an approximate other structure may be used. As described above, according to the present invention, a significant article that enables snow removal over a long distance can be obtained.
