Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a weight-lifting device, and in particular, by changing the gripping state of a support bar to which a weight is detachably attached, it is possible to evenly train the muscles of each part of the arm. The weight lifting device.

[Conventional technology]

A weight lifting device such as a dumbbell or a barbell known in the related art has one linear support bar 1 as shown in FIG.
Then, one or a plurality of disc-shaped weights 2 and 2 are fitted from both ends thereof, and the weights 2 are attached to the support bar 1 by using the fasteners 3.
It is fixed so that it does not escape from the end of the.

[Problems to be solved by the invention]

By the way, the support bar 1 of the weight lifting device described above is merely one metal rod, and therefore, the exercise of the muscles of the arm performed by grasping the support bar 1 with both hands or one hand and moving the weight 2 up and down. There was a drawback that the parts were limited.

That is, for example, the muscles of the arm from the shoulder to the wrist are roughly divided into the inner muscle and the outer muscle, and each of these muscles is also subdivided, so that the muscles of each of these parts can be strengthened individually. However, in the conventional weight lifting device shown in FIG. 7, the gripping mode of the support bar 1 is divided into two types depending on whether the grip of the support bar 1 is held with the wrist of the support bar 1 facing forward or conversely. There is only. Therefore, as described above, the muscles of each part of the arm from the shoulder to the wrist cannot be exercised uniformly, and there is a drawback that only the same muscle is easily biased and exercised.

The present inventor, as a result of research on the above-mentioned problems, in this kind of weight lifting device, by uniformly changing the gripping mode of the wrist without changing the lifting posture of the weight, it is possible to evenly exercise the muscles of each part of the arm. I found that I can do it. Therefore, an object of the present invention is to provide a weight-lifting device that can exercise such arm muscles on average.

[Means for solving problems]

In order to achieve the above object, the weight lifting device according to the present invention mounts a support bar in a symmetrical position of an annular member so that the left and right sides are on the same straight line, and a weight is detachably attached to the support bar. The gripping member is fitted inside the annular member, and the gripping member is composed of a gripping body and a movable adjusting member screwed to the forward and reverse threaded portions provided at both ends of the gripping body. By rotating the grip body,
It is characterized in that the movable adjusting member is configured to be press-fixable to the annular member.

Further, two weight lifting devices described above are provided, and one side support bar of each weight lifting device is fitted and fixed to both ends of the connecting pipe so that it can be used as a barbell.

[Action]

By rotating the gripping member at an arbitrary angle and fixing it to the annular member, the direction of the force applied to the wrist changes when gripping this gripping member and lifting the weight lifting device, and the inner muscles and outer muscles of the arm, etc. The muscles of each part can be evenly and well-trained.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

1 and 2 are front views showing two usage modes of the weight lifting device 4 configured as a dumbbell. In each drawing, 5 is an annular member, and support bars 6 are provided at symmetrical positions of the annular member 5 so that the left and right sides are on the same line. Disc-shaped weights 2 can be detachably fitted from the outer ends of the support bars 6 and 6. One or a plurality of the weights 2 and 2 can be fitted to the support bar 6 to be used as a dumbbell having an appropriate weight. The stopper 3 is provided with a support bar 6 at the tip of the rotary screw member 8.
It is provided so as to be fastened to the outer periphery of.

A gripping member 10 is arranged inside the annular member 5, and is provided so as to be fixed to the annular member 5 after being rotated at an arbitrary angle. In the case of the illustrated example, the gripping member 10 has a cylindrical gripping body 12 having forward and reverse threaded portions 11 and 11, and the forward and reverse threaded portions 11 and 11.
Screw members 13 and 13 screwed to
And a movable adjusting member 15 having arcuate receiving portions 14, 14 integrally provided at the tip of the.

Therefore, the arcuate receiving portions 14 and 14 are connected to the annular member 5.
When the grip body 12 is rotated in the tightening direction, the screw members 13 and 13 extend from both ends thereof, and the arcuate receiving portions 14 and 14 are pressed and fixed to the annular member 5. Further, the grip bodies 12 and 12 contract, the grip body 12 is rotated inside the annular member 5 at an arbitrary angle, and the grip body 12 is slightly rotated again in the tightening direction to be fixed at that position. can do. When the weight lifting device 4 shown in FIG. 1 is in use, the gripping member 10 and the support bars 6 and 6 are located on the same straight line. In this case, the conventional weight lifting device shown in FIG. 7 is used. It can be used like an instrument to train arm muscles. In the use state of FIG. 2, the gripping member 10 is positioned at right angles to the left and right support bars 6, 6, and in this state,
When the gripping member 10 is gripped and the device is lifted, the force exerted on the arm muscles via the wrist is naturally different from that in the case of FIG. 1, and therefore the arm muscles at different parts are trained. is there.

Although not shown, the gripping member 10 can be fixed at any angle and can be fixed at any position between the positions shown in FIG. 1 and FIG. , It is also possible to shift the parts of the arm muscles to be trained little by little.

Next, FIG. 5 and FIG. 6 show the weight lifting device 4 as a barbell using two weight lifting devices 4 as the dibel shown in FIGS. 1 and 2 and connecting them with a connecting pipe 17.
Here is an example of the configuration.

That is, after inserting the support bars 6 of one of the two weight lifting devices 4 and 4 into both ends of the connection pipe 17,
A fixing member 18 is screwed through the connecting bar 17 and the supporting bar 6.

Therefore, the gripping members 10, 10 located at both ends of the connecting pipe 17 can be gripped by both hands and used as a barbell. Also in this case, the gripping member 10,
The fixing angle of 10 can be fixed to any angle exactly as in the case of FIGS. 1 and 2, so that the muscles of each part of the arm can be subdivided and exercised individually and evenly. You can

The annular member 5 is not limited to the annular shape, and may have a polygonal shape. Further, the fixing means of the annular member 5 of the gripping member 10 at an arbitrary angle is not limited to the turnbuckle method as shown in the drawing but may be an engagement pin method (not shown).

[Effect of device]

As described above, according to the weight lifting device of the present invention, since the gripping member forming a part of the support bar is provided so as to be rotatable and fixed at an arbitrary angle, gripping of the wrist when lifting the weight lifting device. You can change the angle. By changing the gripping angle of the gripping member in this way,
The strength of the arm muscles is completely different, so you can subdivide the part you want to train and efficiently strengthen the muscle.
Further, the variable gripping member has an excellent effect such that it is possible to strengthen and train the shoulder portion without putting too much strain on the wrist. In particular, according to the present invention, the gripping member can be fixed to the annular member at an arbitrary angle by rotating the gripping body to press the movable adjusting member against the annular member or releasing the pressing, so that the structure is simplified. And strong.
