Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barbell raising device for lifting a barbell with a small force for changing the weight of a barbell in a weight training field or the like.

[0002]

2. Description of the Related Art Conventionally, in a weight training field, a barbell is handled by a person in charge who manually handles it.
For example, two people exchange the weights attached to both ends of the barbell, one person lifts one of the barbells, and another person exchanges the weights for the shaft of the lifted barbell.

[0003]

However, handling the barbell requires a great deal of force. Especially, it was troublesome to exchange the weights attached to both ends of the barbell.
That is, in the normal state, the weight of the barbell is in contact with the floor, so the barbell must be lifted for replacement, but in general, the barbell is very heavy, and this replacement work is troublesome and also involves danger. Was a thing

The present invention has been made to solve the above problems, and an object of the present invention is to provide a barbell raising tool which can lift a barbell with a small force and easily exchange weights.

[0005]

In order to achieve the above object, the barbell raising device according to the invention of claim 1 has a stabilizing portion which can be stably placed on one plane, and a stabilizing device which is placed. A fulcrum provided in front of the portion, arm portions provided upward in the vicinity of the fulcrum in the placed stable portion, a receiving portion provided at the tip of each arm portion for receiving the barbell shaft,
And a handle provided at the rear of the stabilizing part, wherein the receiving part is located closer to the handle side than the fulcrum.

Further, in the barbell raising tool according to the invention of claim 2, the stabilizing portion further comprises a triangular or quadrangular frame placed on one plane and a bar member continuing to the rear of the frame, and the fulcrum is It is one side on the front side of the triangular or quadrangular frame, the arm portions are provided upward from both ends of the one side, and the handle is provided at the rear end of the bar member with a T-shape.
It is characterized by being provided in a letter shape.

[0007]

When the barbell is lifted, the barbell raising tool as a whole is rotated around the fulcrum by holding the handle, and the shaft of the barbell is received by the receiving portion at the tip of the arm. Then, again, the barbell raising tool is rotated around the fulcrum with the handle in the opposite direction. As a result, the barbell is lifted with a small force by the principle of leverage. The lifted barbell is kept apart from a flat surface such as the floor by the action of the arm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Barbell raising tool 1 according to this embodiment
Is a stabilizing portion 7 including a frame 3 having a triangular central portion and a bar member 5 integrally connected to the rear of the frame 3. This stabilizing portion 7 is formed on the same plane so that it can be stably placed on the floor forming one plane 9. The member of the stabilizing portion 7 may have a rectangular cross section, a circular cross section, or a ring-shaped cross section made of a pipe material. The triangle of the frame 3 is an isosceles triangle, and the base, which is one side in front, serves as a fulcrum 11 for rotating the barbell raising tool 1 as a whole. This fulcrum 1
From both ends of the side that becomes 1, the arm 13 is integrally connected to the upper side of the stable portion 7 in the placed state.
A receiving portion 19 for receiving the shaft 17 of the barbell 15 is provided at the tip of each arm 13. and again,
The rear end of the bar member 5 is integrally connected to the T-shaped handle 21 via a bent portion 6 which is connected to the bar member 5 and rises from the plane 9. Then, as shown in FIG. 3, the receiving portion 19 is positioned closer to the rear side, that is, the handle 21 side than the fulcrum 11 when placed on the floor surface 9. As a result, the arm portion 13 of the barbell raising tool 1 is substantially L-shaped with respect to the stabilizing portion 7, but the angle of the L-shape is an acute angle, and the center of gravity X of the barbell 15 placed on the receiving portion 19 is set. −
Since X is on the receiving portion 7 side as shown in FIG. 3, the barbell 15 is held in a stable state.

The receiving portion 19, as shown in FIG.
The outer holding piece 23 of the U-shaped receiving portion 19 is longer than the inner holding piece 25, and when the barbell 15 is lifted, the outer holding piece 23 facilitates scooping the shaft 17 of the barbell as described later. Has become.

The height A from the receiving portion 19 to the stabilizing portion 7 is
The weight 27 is set to a sufficient size so that the weight 27 does not touch the floor surface 9 with the barbell 15 placed thereon.

The operation of this embodiment will be described below. When lifting the barbell 15, the barbell without the barbell is raised and the tool 1 is first rotated in the counterclockwise direction around the fulcrum 11 from the state of FIG. By this rotation, the arm portion 13 approaches the floor, and the shaft 17 of the barbell 15 can be received in the U-shaped receiving portion 19. At this time, since the outer holding piece 23 of the receiving portion 19 is longer than the inner holding piece 25, the inner holding piece 25 does not get in the way and the shaft 17 can be easily scooped. When the shaft 17 is received deeply into the receiving portion 19, the barbell raising tool 1 as a whole is rotated around the fulcrum 11 with the handle 21, and the barbell 15 is lifted with a small force by the principle of leverage.

After lifting, the stabilizing part 7 may be placed on the floor as shown in FIG. This allows the barbell 15
Since the receiving portion 19 for receiving is closer to the handle 21 side than the fulcrum 11, the barbell 15 can be maintained in a stable state by the barbell raising tool 1. In this state, since the weight 27 is lifted off the floor, the worker does not need to lift the barbell 15 when exchanging the weight 27, and the weight can be easily exchanged in this state. You can

From the function of the triangular frame 3,
The barbell raising tool 1 maintains a stable state even when the weight is replaced. In addition, in the above embodiment, the stabilizing portion 7
Although the frame 3 forming the
Alternatively, it may be circular or the like. Also, the fulcrum 11 is
It may be one side in front of the rectangular frame.

Further, in the above embodiment, the handle 21 is the bar member 5.
Although it was provided in a T shape at the rear end, it may not be T shape in other embodiments. Whatever the shape, when operating the barbell raising tool 1, the stabilizer 7
Anything can be used as long as it can easily rotate.

Further, in the above embodiments, each arm 13
Can be formed of a simple rod or pipe, but as shown by a chain line in FIG. 3, a reinforcing rib 31 may be further provided on the arm 13 by welding. That is, arm 1
3, the receiving portion 19 provided at the tip of the arm portion 13 is the fulcrum 1
Although it is bent at an acute angle so as to be located closer to the handle 21 side than 1 is, a reinforcing rib 31 is welded to this acute angle portion so as to have sufficient strength against the weight of the barbell 15 applied from above. To do.

Further, in the above embodiment, two arm portions 13 and two receiving portions 19 are provided, but the arm portion 1
The number 3 may be three or more. In addition, the receiving portion 19 is 2
Instead of one, it may be made of a material having one long U-shaped cross section that continues to the left and right. Further, in the above-mentioned embodiments, the number of the bar members 5 continuing to the rear of the stabilizing portion 7 is one, but it is of course possible to use a plurality of them, and the present invention is not limited to the embodiments.

[0017]

As described above, according to the present invention, the barbell can be lifted with a small force according to the lever principle. Further, the lifted barbell is kept away from a flat surface such as the floor. Therefore, the work of exchanging the weight of the barbell can be performed easily and safely.
