Description

  The present invention relates to a snow removal tool of variable angle type in which the angle of a snow removal plate with respect to a handle is variable.

  Conventionally, various snow removal tools have been frequently used. However, as shown in the present invention, there is no one that can change the angle of the snow removal plate with respect to the handle.

Snow removal tools are a necessity in snowfall areas. In general, scoops and similar products, load-type hand-held snow removal tools (commonly known as snow dumpers), push-in type snow removal tools (commonly known as snow rassels), and the like are often used. Of these, the push-in type has a pattern formed at a substantially right angle on the center of the convex surface of the curved plate as the push-in plate, and is used for extruding snow on the road surface.
Snow accumulates not only on the road surface but also on the roof of a house. If a certain amount of snow is deposited on a steep roof, it falls automatically due to its own weight, but if the slope is relatively gentle, this snow must be drained manually. I must. In this case, a person goes up on the roof to remove snow. Also, as snow accumulates, it hangs down from the lower edge of the roof. On the back of the snow, a little melted at daytime temperature freezes at night and increases in weight, and this fall is dangerous. Sometimes the danger increases if it melts in warm air and becomes icicles.
In such a case, there is no appropriate tool for artificially dropping the snow that has been caught, and it is hit with a general snow removal tool, but it is not sufficient, and the development of a more appropriate tool is desired. Yes.
The present invention was invented in order to solve the problems related to the conventional snow removal tool as described above, and by changing the angle of the handle with respect to the snow removal plate, both pressing and pulling operations were made possible. It was developed for the purpose of providing more useful snow removal tools.

The present invention has the following configuration as means for solving the problems.
That is, a snow removing plate having an appropriately shaped curved plate body is provided, a connecting tube made of a T-shaped tube body in which a female screw is engraved is provided in the center of the convex surface of the snow removing plate, and a handle in which an external screw is engraved is provided on one end thereof. A handle is screwed onto the connecting pipe. The present invention is a variable angle snow remover having the above-described configuration.
In addition, it may replace with fixation by the screwing system of a connecting pipe and a handle | steering-wheel, and you may comprise using the rotation mechanism part system by a pin and a cutting part.

  According to the present invention, since the angle of the handle with respect to the snow removal board is variable, it is possible to remove snow as well as pushing snow removal, and to obtain a useful snow removal tool capable of removing snow on the roof in addition to removing snow on the road surface. Can do. In addition to snow removal, it can also be used for applications such as earth and sand and puddles.

Hereinafter, embodiments of the present invention will be described.
In the figure, 1 is a snow removing plate made of synthetic resin, which is a generally arcuate plate body in a front view with its left and right ends gently bent, and a T-shaped connecting tube 2 is fixed to the center of the convex surface as shown in FIG. Yes. The connecting pipe is opened at the end and is internally threaded. Reference numeral 3 denotes an expandable handle. A joint 5 is provided on an appropriately long outer tube 4 having an external thread engraved at one end thereof, and an inner tube 6 having an outer diameter that can be inserted into the outer tube is connected. When turned in one direction, the inner tube is fixed with respect to the outer tube, and when turned in the opposite direction, the fixation is released. The mechanism has the same configuration as that used for a commercially available snow removal brush. A handle 7 is fixed to the other end of the inner tube. The above is one embodiment of the present invention.
When using the present invention as a general snow raschel, as shown in FIG. 2, a male screw engraved at the outer tube end of the telescopic handle is screwed onto one female screw of the connecting tube, and the handle to the snow removal plate is almost The snow is removed by pushing the snow surface with this snow removal board.
Next, when the pattern is changed as shown in FIG. 3, the angle of the snow removal board changes, and it is possible to remove snow by pulling the snow removal board toward the front, and it can be used when dropping snow, snow canopies, etc. on the roof.

4 to 9 show other examples of the present invention.
In the figure, 10 is a snow removal plate similar to the previous example, and 11 is a connecting pipe formed by a T-shaped short pipe having a plurality of through holes formed at appropriate positions. Reference numeral 12 denotes a stretchable pattern similar to the previous example (excluding some), and a handle is attached to one end thereof. A part of this stretchable pattern has a larger diameter, and is provided with a turning mechanism portion 13 in which a pair of opposed cut portions are formed to be bifurcated. The inner diameter of the bifurcated portion is equal to the outer diameter of the connecting pipe 11 and a through hole is formed at an appropriate position on the side surface of the bifurcated portion.
This through hole coincides with the through hole of the connecting pipe 11, and a bolt-shaped main pin 14 is inserted therethrough and two nuts 15 are screwed. Reference numeral 16 denotes a secondary pin made of a round bar having a large head, and is inserted into the through hole. A hole is formed in a portion protruding from the through hole, and the split pin 17 is inserted and locked therein. When the split pin is removed from the secondary pin provided on the rotation mechanism of the telescopic handle, the secondary pin can be removed, and when the handle is rotated 90 degrees around the main pin, the other hole of the connecting tube is inserted into the secondary pin. By aligning with the hole that has been made, and inserting and locking the secondary pin again, the snow removal plate can be turned 90 degrees from the above state, and the same effect as the previous example can be exhibited. Can do.

In this example, a rotating mechanism method is used instead of the screwing method of the previous example. As described above, the rotating mechanism part cuts away a part of the extendable handle, and the inner diameter thereof coincides with the outer diameter of the connecting pipe.
The rotating mechanism can be rotated around the main pin, and its position can be fixed and changed by the auxiliary pin. When the sub-pin is removed and rotated, the bifurcated portion moves along the inner diameter of the connecting pipe, so that the interval between the two temporarily extends. However, the head and nut of the main pin are bifurcated as shown in FIG. Since it is located at some distance from the external surface, this rotation is not hindered. Further, because of the double nut system, the nut position with respect to the main pin is stably fixed. In this example, the split pin method is used to prevent the secondary pin from falling off, but other methods, for example, a screwing method like the main pin may be used.

Although the present invention has been described above, the present invention is characterized in that the angular position of the snow removal plate can be changed with respect to the handle. The conventional product does not have this function, and it is made to push and remove snow. Therefore, if snow removal is used by pulling, the snow escapes to the concave side along the convex surface of the snow removal plate, and the purpose cannot be achieved. However, since the position of the snow removal board can be changed by 90 degrees in the present invention, it is possible to remove snow by pulling using the convex surface of the snow removal board. In the above-described example, the stretchable pattern is attached to the center of the convex surface of the snow removal board at a right angle at the initial position, but the present invention is not limited to this and may be configured as another angle setting.
The above-described example is an example of implementation, and another configuration with approximation may be used.
As described above, a useful snow removal tool that is more convenient to use can be obtained by the present invention.
