Description

[Technical Field]

[0001] The present invention relates to a snow removal tool that can be connected to two identical snow removal tools to perform snow removal work as needed. [Background technology]

[0002] Although a variety of snow removal tools have been used up until now, there have been no snow removal tools that can be used by interconnecting snow removal tools of the same type as shown in the present invention. Summary of the Invention [Problem to be solved by the invention]

[0003] Snow removal equipment is essential in snowy regions. Commonly used snow removal equipment includes shovels, snow plows, snow dumps, and snow pushers, and has the following features: (a) Shovel They have been used for a long time and can handle hard packed snow, but they cannot handle large amounts of snow at once. Most are made of metal. (b) Snow shoveling Many of them have longer handles than shovels, and are suitable for clearing relatively light, fresh snow. They are made of synthetic resin and are not as strong as shovels, so they are not suitable for clearing hard or packed snow. Also, they cannot clear large amounts of snow at once. (c) Snow dump Compared to other snow removal tools, the bucket size is large, allowing for a relatively large amount of snow to be removed at one time. However, due to the relationship between the bottom of the bucket and the snowy road surface, about 1 to 2 centimeters of snow remains when removing the snow, and the snow has a large resistance pressure, so it requires arm, leg, and back strength, and is not suitable for women or the elderly. (d) Snow pusher It pushes snow that has accumulated on a flat surface and creates relatively little resistance, but it is not suitable for clearing frozen snow, kicking up snow, or clearing snow from uneven surfaces. Users select and use each of the above snow removal tools as appropriate, but each has its own advantages and disadvantages. When clearing snow from large, flat areas such as parking lots, it is often necessary to remove the snow immediately after it has fallen. While there is a demand for easy-to-use snow removal equipment suitable for this purpose, no such equipment has yet been found. SUMMARY OF THE INVENTION In view of the above, the present invention provides a new snow removal means to replace conventional snow removal means, and provides a useful tool that can also be used to remove snow from large, flat areas. [Means for solving the problem]

[0004] As a means for solving the problems, the present invention has the following configuration. That is, one aspect of the present invention is This snow removal tool is comprised of a snow removal body with a generally rectangular bottom and lateral side walls rising continuously and a rear sloping side wall, and a handle attached to the snow removal body. An engaging connector is provided on one side wall of the snow removal body, and the engaging connector is an L-shaped plate of a predetermined length attached to the upper surface of the side wall of the snow removal body. On the upper surface of the opposing side wall, an engaging connector that can be detached and engaged with the engaging connector is provided, and the engaging connector is formed from an upwardly protruding L-shaped small plate and a small plate that stands upright a predetermined distance from the small plate. The engaging connectors are configured to prevent mutual separation in horizontal and vertical directions when engaged with each other, allowing adjacent snow removal tools to be attached, detached, and engaged with each other. Standing pieces are provided on the top and bottom surfaces of the snow removal body. Another aspect of the present invention is This detachable connecting snow removal tool is characterized by having a snow removal body with a generally rectangular bottom and lateral side walls rising continuously and a rear sloping side wall, and a handle attached to the snow removal body. An engaging connector is attached to one side wall of the snow removal body, and an engaging groove is provided at the front end of an L-shaped plate of a predetermined length attached to the upper surface of the side wall of the snow removal body. Another engaging connector is attached to the upper surface of the opposing side wall, and is detachably attached to the engaging connector. The engaging connector is formed as a slit on the upper surface of the side wall, and the engaging connectors are configured to prevent mutual separation in horizontal and vertical directions when engaged with each other, allowing adjacent snow removal tools to be attached, detached, and engaged with each other. Standing pieces are provided on the top and bottom surfaces of the snow removal body. Furthermore, another aspect of the present invention is This snow removal tool is comprised of a snow removal body with a generally rectangular base and lateral side walls rising continuously and a rear sloping side wall, and a handle attached to the snow removal body. An engaging connector is provided on one side wall of the snow removal body, and this engaging connector is a small, protruding plate with a slit. On the upper surface of the opposing side wall, another engaging connector that can be detached and engaged with the engaging connector is provided, and this engaging connector is an upwardly protruding small plate with a cutout. The engaging connectors are formed to prevent mutual separation in horizontal and vertical directions when engaged with each other, allowing adjacent snow removal tools to be attached, detached, and engaged with each other. Standing pieces are provided on the top and bottom surfaces of the snow removal body. [Effects of the Invention]

[0005] The present invention has the following effects. 1. Like a snow dump or snow pusher, it can push snow that has accumulated on a smooth snowy surface to remove it, and two identical snow removal tools can be connected together for use, allowing one person to efficiently remove snow from a wide area. 2. The snow removal tools can be attached and detached from each other, so they can be separated and used as general snow removal tools. 3. The attachment and detachment method is by mutual engagement of the engaging connecting bodies, so attachment and detachment can be easily performed. 4. Because the snow removal device is placed on the snowy road surface to remove snow, the angle of the bottom of the snow removal device to the snowy road surface is nearly parallel, making it easier to slide than other snow removal devices, and the part of the snow removal device that carries the snow is shallow, making it easy for women and the elderly to use. 5. By providing standing pieces on the top and bottom of the snow removal body, the stability of the snow removal body in the direction of travel when inserted into falling snow can be increased, and the strength of the snow removal body can be increased.

[0007] Hereinafter, an embodiment of the present invention will be described. In the figure, reference numeral 1 denotes a snow removal unit. This snow removal unit has a roughly rectangular base with a rising side wall 2, which is triangular in shape when viewed from the side and is formed on both sides of the base, excluding the front and rear. The side opposite the front is formed as an inclined side wall 3, and a round rod-shaped handle 4 is fixed perpendicular to the side wall surface. The snow removal unit is made of synthetic resin, and the handle is made of wood. Reference numeral 5 denotes an engaging connector A. This engaging connector A is a plate-like portion of a predetermined length that is L-shaped when viewed from the front, and is formed integrally with the upper surface of the middle of one of the side walls of the snow removal body. Reference numeral 6 denotes an engaging connector B. This engaging connecting body B is a small plate-like portion that is integrally formed with the side wall on the upper surface of the side wall opposite the engaging connecting body A, and is a tongue-like portion that first protrudes obliquely backward from the upper surface of the side wall, and then protrudes parallel to the upper surface of the side wall. Reference numeral 7 denotes an engaging connector C, which is a part formed integrally with the engaging connector B at a predetermined distance on the upper surface of the side wall. This engaging connection body C is a small plate-like body that stands upright, and the distance between it and engaging connection body B is set slightly longer than the length of the engaging connection body A. In addition, a rib 8 for reinforcement is formed integrally.

[0008] The present invention uses two identical products in combination. The assembly method is as follows: First, place two snow removal units of the present invention close to each other in the same direction, then lift one of the snow removal units and engage connecting member A with connecting members B and C. That is, tilt the snow removal unit and slide the leading edge of connecting body A diagonally into connecting body B, aligning the two snow removal units so that the top and bottom of the two snow removal units are parallel. Then, the rear end of connecting body A is positioned very close to connecting body C, and both snow removal units are aligned in the same direction when engaged. In this state, both snow removal units are side by side in parallel, and because unit A is positioned between units B and C and cannot slide back and forth, and the tip of unit A is positioned in the gap between unit B and the upper surface of the side wall directly below it, the snow removal units are prevented from moving apart vertically. Therefore, because both snow removal units are roughly integrated, they can perform their snow removal function together, allowing a wider area to be cleared at once.

[0009] 4 to 19 show other and modified examples of the present invention. In the figures, 10 denotes an engaging connector D, which has a similar structure to the engaging connector A of the first example, but has an engaging groove 11 at its front end. A slit 12 is formed on the top surface of the other side wall, and the engaging connector D is inserted into this slit and engaged, with the engaging groove fitting into the slit to stabilize and fix its position. This is the second example of the present invention. 7 to 9 show a third embodiment of the present invention. Reference numeral 20 denotes a small, flat engaging connector E that is provided on the upper surface of the snow removal unit side wall midway, and has a slit 21. Reference numeral 22 denotes an engaging connector F, which is a protruding part that is roughly rectangular parallelepiped, and has a cutout 23 formed in the lower front part. These two connecting bodies fit together as shown in FIG. 9, and the cut-out portions come into contact with the slits, preventing them from accidentally falling off. 10 and 11 show a fourth embodiment of the present invention. 30 denotes an engaging connecting body G, which is a small, flat plate-like part that protrudes from the side wall of the snow removal body, with a portion of its rear end cut away to form a small tongue-like part 31. 32 denotes a slit provided in the other side wall of the snow removal body. The engaging connecting body G is inserted into the slit 32 and locked, so that both snow removal bodies are in an engaged relationship. Furthermore, the small tongue-shaped portions fit into the inside of the slits, preventing them from falling off each other. 12 and 13 show a fifth embodiment of the present invention. 40 is an engaging connector H similar to the previous embodiment, but the tongue portion 41 formed by the cutout is located in the front. 42 is a stepped recess formed on the upper surface of the side wall, with a base area slightly larger than that of engaging connector H. A cutout gap 43 is located in front of this recess, and when engaged, the tongue portion 41 fits within this cutout gap 43, preventing it from falling off.

[0010] 16 to 18 show another embodiment of the present invention. In the figure, the reference numeral 50 denotes the upper main upright, a piece that extends from the top of the flat part of the snow removal body near the tip to part of the rear end, and a pair of these are installed in the center of the snow removal body. The height of these uprights is small at the tip and gradually increases toward the rear, as is the case with the secondary uprights described below. The secondary pieces 51 are slightly smaller than the upper main piece and are provided in pairs, spaced apart from the upper main piece. These secondary pieces are hard plates, one part of which protrudes vertically upward from the top surface of the snow removal body, and the other part protrudes downward from the bottom surface of the snow removal body, penetrating the snow removal body. The downward protruding portion has a greater protruding distance toward the rear of the snow removal body. The snow removal body has a rigid plate structure that protrudes upward and downward, providing sufficient strength. The secondary stand is integrated with the snow removal body when it is molded.

[0011] In this example, the snow removal body has upright sections on the top and bottom of the flat part, so that the bottom of the snow scooped up by the snow removal body is cut up by these upright sections, making it easier to determine the direction of the snow removal body when scooping up snow and also easier to throw the scooped up snow. The lower part of the secondary stand also helps stabilize the movement of the snowplow, and when snow falls on a packed snow surface, the lower end of the secondary stand comes into contact with the packed snow, reducing resistance to the movement. Furthermore, these stand members increase the strength of the snowplow. As mentioned above, each stand member is designed so that its tip is small and gradually increases in height toward the rear, reducing resistance when the snowplow is inserted into the falling snow.

[0012] As described above, the present invention is characterized by the fact that two identical snow removal tools can be attached and detached, and that these snow removal tools can be connected in parallel as needed to perform snow removal work, making it possible to remove snow from a wide area at once. In the past, there was no such tool, so snow removal was inconvenient, but this invention has eliminated this inconvenience. In the described example, the engaging connector is described as being integrally formed with the snow removal unit, but as shown in Figure 14, it may be a separate item that is screwed onto the snow removal unit. As a variation of the previously described alternative, the secondary stand may simply be formed integrally with the snow removal unit in a stand-like shape. The previously described example is merely an example, and other similar configurations may be used. As described above, the present invention provides a new and useful means for removing snow.
