Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to a weight carrying aid. [Background technology]

[0002] For example, the task of workers carrying heavy objects such as automobile tires and wheels is not an easy one due to their weight. A typical heavy object transport device that makes this task easier is a cart (see Patent Document 1). While a cart has the advantage of being able to transport multiple heavy objects at once, the effort required to prepare a cart is cumbersome when transporting a single heavy object or a relatively short distance. Furthermore, a cart requires that the ground be level. Therefore, there is a demand for a transport device that is useful in such situations. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-195248 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to solve the above-mentioned problems, one object of the present disclosure is to provide a heavy body transport aid that allows a worker to easily transport a heavy body and that is easy for the worker to wear. [Means for solving the problem]

[0005] The weight carrying aid of the present disclosure is a main body portion formed by connecting a forward extension portion that extends forward in a manner to be placed on the shoulder of a worker and a downward extension portion that extends downward on the back side of the worker; a support portion provided on the forward extension portion, on which a worker can place a wrist portion of the hand supporting the weight body when the worker extends the arm forward along the forward extension portion; a movement preventing portion that wraps around the front side of the worker's body at the tip end side of the downward extension portion and prevents the tip end side of the downward extension portion from moving backward; Equipped with. [Effects of the Invention]

[0006] The weight-carrying aid according to the present disclosure is worn by placing the base end (downward extension) of the forward extension of the L-shaped main body on the worker's shoulder, with the forward extension projecting forward, while the downward extension is positioned so as to extend downward along the worker's back, and the movement-blocking portion at the distal (lower) end of the downward extension wraps around the front of the worker's body (e.g., abdomen). This makes the device easy to wear. When carrying a weight, the worker places their wrist on the support portion at the distal end of the forward extension and grasps the handle or hook of the weight with their hand. In this state, the worker moves their body so that the distal end of the forward extension moves upward by, for example, straightening their bent knees, and begins walking to carry the weight. By wearing this heavy object carrying aid, not only is the weight of the heavy object supported by the shoulders, but the force (rotational force) that acts on the tip of the forward extension (support part) is supported by the worker's body (for example, abdomen) as the movement-preventing part that wraps around in front of the worker's body (for example, abdomen), making it possible to carry the heavy object easily without using much arm strength. Also, because the worker carries it with their own feet, steps and the like are not a problem. [Brief explanation of the drawings]

[0007] [Figure 1] FIG. 1 is a perspective view showing a simplified example of a weight transport aid. [Figure 2] FIG. 2 is an explanatory diagram illustrating the state in which the weight transport aid of FIG. 1 is used. [Figure 3] 2. FIG. 4 is an explanatory diagram illustrating a usage state of the weight transport aid of FIG. 1 different from that of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] 1 and 2 show an embodiment of an aid for transporting a heavy body 1. The aid for transporting a heavy body 1 comprises a main body 2, a support part 3, and a movement-preventing part 4.

[0009] The main body 2 is L-shaped, with a forward extending portion 2A extending forward so as to rest on the shoulders of the worker W, and a downward extending portion 2B extending downward from the back side of the worker W. In this embodiment, the main body 2 is made of an L-shaped metal pipe material, and the portion that comes into contact with the shoulders and back of the worker W (the middle portion including the bent portion) is covered with an elastic material 2C. In this embodiment, this elastic material 2C is adhesively fixed to the forward extending portion 2A and the downward extending portion 2B, or is fixed by a binding member (not shown). In this embodiment, the forward extending portion 2A and the downward extending portion 2B each extend linearly. The main body 2 is not limited to the above as long as it is configured to be able to support the weight of the object to be transported (heavy body). The main body 2 can be modified in various ways, for example, the forward extension 2A and the downward extension 2B do not have to be linear, and the material can be made of resin.

[0010] The support part 3 is provided on the forward extension part 2A, which extends forward so as to rest on the shoulder of the worker W. When the worker W stretches his / her arm forward along the forward extension part 2A, the worker W can place the wrist of his / her arm on the forward extension part 2A. In this embodiment, the support part 3 extends horizontally from the tip of the forward extension part 2A in a direction different from the forward extension part 2A. Specifically, the support part 3 protrudes horizontally and perpendicularly from the tip of the forward extension part 2A. Furthermore, the support part 3 is inserted into a mounting hole in the forward extension part 2A, which is made of a metal pipe material, and is fastened and fixed with screws, bolts, or the like. In this embodiment, the support part 3 has a metal part 3A, which forms a core extending in the extension direction, covered with an elastic material 3B. The support portion 3 is not limited to the above, as long as it is configured so that the wrist of the worker W can be placed on it when the worker W extends his arm forward. For example, the tip (front end) of the forward extension portion 2A may be bent and the part at the end of the bend may be the support portion 3, or the part on the tip side of the linear forward extension portion 2A may be the support portion 3. The support portion 3 may also be made of resin, and various modifications are possible.

[0011] The movement-preventing portion 4 is configured to wrap around the front side of the worker W's body at the tip of the downward extension portion 2B and prevent the tip of the downward extension portion from moving backward (rotating backward). In this embodiment, the movement-preventing portion 4 has a cloth belt 4A and a resin buckle 4B, and is circularized by engaging a resin engagement portion 4C provided on the belt 4A with the buckle 4B. Specifically, by inserting the tip 4C of one belt 4A into the buckle portion 4B provided on the tip side of the other belt 4A, the inserted belt 4A is fixed to the buckle portion 4B at any position so as not to slip out. This causes the belt 4A to be circularized. The circularization of the belt 4A includes not only the circularization of the belt 4A alone but also the circularization of the belt 4A and the downward extension portion 2B. Note that the movement-preventing portion 4 is not limited to the above, as long as it is configured to wrap around the front side of the body of the worker W at the tip side of the downward extending portion 2B and prevent the downward extending portion from moving backward. The movement-preventing portion 4 may be, for example, a portion in which the tip (lower end) of the downward extending portion 2B bends forward and extends in a curved manner to surround the body of the worker W, or the material may be changed, and various other modifications are possible.

[0012] A method of using the weight transport aid 1 according to this embodiment will be described.

[0013] As shown in FIG. 2, the base end (downward extension 2B side) of the forward extension 2A of the L-shaped main body 2 is placed on the shoulder of the worker W, causing the forward extension 2A to protrude in front of the worker W. Meanwhile, the downward extension 2B is positioned so as to extend downward along the back of the worker W, and the movement-preventing portion 4 at its tip wraps around the front side of the worker W's body (e.g., abdomen), preventing the tip of the downward extension 2B from moving backward by contacting it from the front side. Here, the belt 4A is wrapped around the abdomen of the worker W, and the tip 4C of one belt 4A is inserted into the buckle 4B of the other belt 4A and secured to prevent it from slipping off, forming a loop and wrapping around the front side of the worker W's body (e.g., abdomen). This allows the worker W to wear the weight transport aid 1.

[0014] When worker W carries weight body X1, he stretches his arm forward along the forward extension 2A. Then, with his wrist resting on the support portion 3 at the tip of the forward extension 2A, he grasps the handle portion x1 of weight body X1 with his hand (at the tip of the wrist), or with his hand grasping the handle portion x1 of weight body X1, he places his wrist (at the front of his hand) on the support portion 3 at the tip of the forward extension 2A. Then, worker W moves his body so that the tip of the forward extension is lifted by, for example, straightening his bent body or straightening his bent knees, and starts moving with his feet (for example, walking) to start carrying weight body X1. The worker W not only supports the weight of the weight body X1 on his shoulders, but also the force (rotational force) that causes the tip end (support part) of the forward extension part to move downward due to the weight of the weight body X1 is supported by the movement prevention part 4 that wraps around the front of the worker's body (for example, the abdomen), allowing the worker W to easily carry the weight body X1 with almost no arm strength. The weight body X1 in this embodiment is assumed to be a wheel of an automobile.

[0015] The handle x1 of the weight body X1 may be a hook. For example, as shown in FIG. 3, the weight body X2 is provided with a hook x2 instead of the handle x1, and the worker W wearing the weight body transport aid 1 hooks the hook x2 of the weight body X2 onto the support part 3 at the tip of the forward extension part 2A. The hook x2 may extend beyond the support part 3 and hook onto the tip of the forward extension part 2A. In this state, the worker W can move his / her body so that the tip of the forward extension part is lifted by, for example, straightening his / her bent body or straightening his / her bent knees, and then start transporting the weight body X2 by moving with his / her feet.

[0016] It should be noted that the weight bodies such as X1 and X2 may be other weight bodies transported by the weight body transporting aid 1. In this embodiment, the weight bodies such as X1 and X2 are provided with a handle portion x1 or a hook portion x2.

[0017] The present disclosure is not limited to the embodiments described above and in the drawings. For example, any combination of features of the above-described or following embodiments is possible within a range that does not contradict. Furthermore, any feature of the above-described or following embodiments may be omitted unless explicitly stated as essential. Furthermore, the above-described embodiments may be modified.

[0018] Furthermore, the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is not limited to the embodiments disclosed herein, but is intended to include all modifications within the scope indicated by the claims or the scope equivalent to the claims.
