The following describes in detail a preferred embodiment of the present invention.

The force application assist device 10 will be described with reference to Figures 1 and 2. The force application assist device 10 is intended to assist a user in applying force to a solid object 60. The force application assist device 10 includes a fixing part 40 for fixing the solid object 60, a connecting body 30 connected to the fixing part 40, and a handle 20 rotatably connected to the connecting body 30. The force application assist device 10 assists a user in applying a force applied to the handle 20 to the solid object 60 by the user holding the handle 20. The force application assist device 10 can assist in moving the solid object 60.

By attaching the shoulder strap member 50 to the handle 20, the solid object 60 can be fixed to the fixing part 40, the shoulder strap member 50 can be hung on the shoulder, and the handle 20 can be held in the hand, allowing the force of the hand and shoulder to be applied to the solid object 60. The handle 20 can be provided with a shoulder strap member anchoring part 22 for attaching the shoulder strap member 50 that can be hung on the shoulder. By attaching the shoulder strap member 50 to the shoulder strap member anchoring part 22, it is possible to prevent the shoulder strap member anchoring part 22 from moving in the direction in which the handle 20 extends. The shoulder strap member 50 can be configured, for example, as a shoulder belt.

The connecting body 30 and the handle 20 can be rotatable in multiple directions. When the handle 20, the connecting body 30, and the fixing part 40 are aligned in a straight line, the handle 20 can be moved in a 360-degree direction relative to the fixing part 40, centered on the axis of the alignment direction. The connecting body 30 includes a fixing part connecting part 36 that is connected to the fixing part 40 via a pivot shaft 36a, and the fixing part 40 and the connecting body 30 can be provided to be rotatable around the pivot shaft 36a.

The connecting body 30 can have a universal joint, and the handle 20 can be connected to the universal joint directly or via a fixed joint. The connecting body 30 has two universal joints, at least two of which are connected in series, and the universal joints are connected to each other via fixed joints to form a multiple joint structure (e.g., a double joint), which makes it easier to control the angle of the handle 20 depending on the state in which the solid object 60 is placed, and makes it easier to move the solid object 60 in a specified direction.

The universal joint can be, for example, a cross-type universal joint or a ball joint.

The connecting body 30 may include a rotary shaft coupling 34. The rotary shaft coupling 34 is provided between the universal joint and the fixed part 40, and the fixed part 40 may be rotatable around the rotary shaft coupling 34. In the example of the force application support tool 10 shown in Figures 1 and 2, the connecting body 30 is configured in the order of the fixed part connecting part 36, the rotary shaft coupling 34, the first universal joint 32a, and the second universal joint 32b from the side of the fixed part 4040, but is not limited to this embodiment.

The handle 20 is appropriately selected taking into consideration the weight of the solid object 60, and although not limited thereto, a golf shaft can be used.

The fixing part 40 is not particularly limited as long as it can fix the solid object 60, but for example, a ratchet buckle or a known fastening device can be applied. The ratchet buckle includes a buckle and a belt 42 fixed to one end of the buckle, and the other end of the belt 42 can be fixed to the buckle, and the belt 42 is tightened by rotating the buckle. The fixing part 40 may function as the fixing part 40 by wrapping a robe or the like around the solid object 60.

This embodiment makes it easy to move solid objects such as trees and bamboo while avoiding ground conditions and obstacles in the movement area. It also makes it easy to apply pressure to the tree or bamboo being cut in a specific direction when cutting the tree or bamboo.

The inventor of the present application explains the background that led to the invention. The inventor of the present application has been practicing environmental conservation for many years, and had an idea that he would like to contribute to alleviating various problems (aging, lack of successors, expansion of abandoned bamboo forests, degradation of farmland, damage by vermin, etc.) caused by the increase in abandoned bamboo forests (groves) seen nationwide in recent years. When he looked at actual bamboo forests (maintenance), he realized that many of them are small and privately owned, located on sloping land close to mountain forests where work is dangerous, and that transportation after felling is dangerous and involves hard work.

Therefore, we thought that we needed a tool that would reduce risk and labor, aiming to allow many people (including women and the elderly) to safely, easily, and casually participate in bamboo forest maintenance. When felling, we found a need for a tool that can keep the base of the falling bamboo at a safe distance, and pull the bamboo that gets caught on the way to the ground to safely fall to the ground, and can be moved to any location safely and with little labor, and is also light and easy to carry, and the fixing part is easy to operate. In other words, we came up with the problem that there was no tool to easily transport felled trees and bamboo by hand, and have completed the force application support tool 10 according to the embodiment. The areas where trees and bamboo are felled are often obstacles such as slopes and other trees, making it very difficult to carry the trees and bamboo. Trees and bamboo are heavy and move along with the ground. For this reason, even if the wood or bamboo fixed to the fixed part 40 moves along the ground, if the handle 20 can rotate relative to the fixed part 40 and be moved without changing the position of the handle, it was discovered that the wood or bamboo can be easily transported, and this embodiment was completed.

The inventors of the present application also discovered that by attaching the shoulder strap member 50 to the handle 20, it is possible to utilize the strength of the shoulders in addition to the strength of the hands, making it easier to apply force to the solid object 60 using the entire body rather than just the strength of the hands.

The force application support tool 10 can be used in the following ways, for example. (1) As a first mode, as shown in FIG. 3, it is used to pull objects to be cut down, such as trees or bamboo. (2) As a second mode, it is used to pull a solid object 60 that is used to pull cut trees or bamboo. As shown in FIG. 5, multiple people may each hold a force application support tool 10 and use it to move a solid object 60 at the same time.

The force application support device 10 is suitable for use with long objects, such as elongated objects that are easily affected by the conditions of the area in which they are moved, and is particularly useful when transporting wood or bamboo (e.g. felled trees).

This embodiment can be modified in various ways within the scope of the present invention.
