Abstract

PURPOSE:To enhance the efficiency of operations as well as relieve the amount of labor by using a wide-angle handle formed by connecting a pipe with two bend portions provided in main handle trunks parallelized. CONSTITUTION:Upper and lower bend portions A and B are provided for the main trucks 2 of a snow damper, a wide-angle handle 3 is provided between both the bend portions A and B, and a connecting lever 4 is also provided between the bend portions A and B. The loading and damping operations of snow at high places can thus be made easier by grasping the bend portion A of the handle 3. The discharge of snow even to lower places can also be easily made without the needs to lower the attitude of man by bending his waist.

Description

[Detailed Description of the Invention] Snow dumpers, commonly known as snow dumpers, are widely used as snow removal transportation tools, but existing snow dumpers have a limited length and angle of the steering section of the handle, making it difficult to load items in high places or in low places. For example, when removing snow from a roof, most of the snow from the eaves falls off, but most people do not want to go out to the eaves for fear of falling off the roof. You will be pushing down the snow from a low level, and at the moment the snow is released from the snow dumper, you will be forced to bend your back. This is due to the friction of the released snow and the inertia of the snow dumper, and your hands will be on the handle. Because you are being pulled, you have to respond to this pulling force and hold back the handle.This special fat guy naturally bends his waist and maintains a low posture to hold the handle.However, if you bend your waist and maintain a low posture, The tip of the dump truck rises, and as it rises, it becomes difficult to release the snow. This is extremely dangerous, depending on the location. The snow in the X-rays is located at a high location, but if it accumulates more than 1 meter. In order to load this, it is necessary to raise the handlebars.If you raise the handlebars, you will not be able to apply as much force as you want, but the angular resistance of the back of the dump truck will add to the difficulty, making it even more difficult to load snow. In order to drop the dump truck onto the eaves, the inertia of the dump truck and the snow is increasing, so you have to use more force than mentioned above to hold the handlebars in place.In order to use a large force to hold the truck in place, the body's posture naturally becomes lower, and if it gets lower, the dump truck will drop. The tip rises and is difficult to release, resulting in a vicious cycle being repeated. Also, in order to efficiently remove snow from lightning, it is necessary to divide the snow into sections to fill the dump truck, just like with a shovel, but with limited handles, it is difficult to even lift the dump truck. Since there is, it is extremely difficult to pinpoint the boundaries and push through them, combined with the angular resistance on the back side. Also, when removing snow, it is not always necessary to dump it from a high place to a low place.In some cases, snow may be piled up high and thrown away, and in this case, it is troublesome to dump the snow from a dump truck that has been pushed up to a high place. . Therefore, in order to solve these problems, the angle of the handle can be made variable and the angle can be changed according to the conditions, which would theoretically solve the problem, but it does not work in practice because the conditions themselves change too drastically. Even if the angle can be changed with a single touch, the operation requires a minimum amount of time, and if the angle can be changed with a single touch, there will be structural problems.

Therefore, the purpose of this invention is to rationally solve these problems, reduce labor, and increase work efficiency.

Next, I will explain this configuration with reference to the drawings. Figure 1 shows an example of a snow dumper with a wide-angle handle. The handle main body 2 with 1 as the mounting part at both ends is connected to the 4
5 is the trunk that supports 2, and the dotted line 7 indicates the installation position of the trunk that supports 4.However, if the main trunk 2 is strong, 7 is unnecessary.In such a structure, between the curved part AB and It has wide-angle handles 3 on both sides.

Figure 2 shows two sides of the pipe, where the main stem 2 with 1 as the attachment point at both ends is connected at 4 through the bend C, and both ends of the pipe with A as the bend are fixed to B and 6. The structure consists of wide-angle handles 3 on both sides between AB and AB.

In each figure, the position B or 4 corresponds to the upper limit of the handle, and the position A corresponds to the lower limit. 3 connects the top and bottom of the handle. Therefore, the longer the length of 3, the wider the angle width, but do not make it too long. 6A3B (as long as the part corresponding to 3rd grade is configured, it can be transformed into any other shape).

Next, how to use this handle is to grasp the appropriate part at most depending on the position of the snow to be removed, that is, the height or lowness, but for example, loading or discharging snow from high places is 3 This is made easier by grasping the lower limit curved part A of the handle.This is because by holding the lower limit of the handle, the height at which the handle is lifted can be lowered by the length of 3, making it easier to apply force. It is incomparable at all to having an upper limit of Compared to the case where there is an upper limit, it is released easily.Therefore, even when removing snow from places where there is a danger of falling, such as roofs, cliffs, and rivers, there is no risk of being drawn into a snow dump. This makes it possible to perform very safe work, and even when pulling the snow dumper backwards by applying the inertia of a stationary snow dumper full of snow, if you pull it with the lower limit, you can be sure to pull it out cleanly. Also, when separating the snow with a snow dump, by making sure that both lower limits are vertical, and supporting the lower limit as a fulcrum and the upper lower limit as a point of effort, the important dump can be lifted stably and easily without difficulty. Therefore, it is possible to precisely divide the area to be divided, and when the snow divided in this way is fully piled up, the amount of snow is about 0 with a large snow dumper.
．． More than 25 cubic meters of snow can be loaded.In other words, 1 cubic meter of snow can be removed by loading it four times.For example, if you divide the snow on the roof like this, you can remove 1 meter of snow from an area of 100 square meters. In this case, the work time for one person is about 2 hours, which is more than twice the efficiency as in the case without partitions, and since you can work without bending your back, you can do snow removal work safely and comfortably without getting tired.It is also expensive. When pushing up a place or removing snow from a flat place, holding the wide-angle handle vertically at the appropriate point makes it much easier to maintain a stable working posture compared to holding the wide-angle handle horizontally. This wide-angle 71 handle has the same effect as that of a handle that automatically changes the angle and length of the handle by gripping the appropriate part of the handle (according to the working conditions). .
