Abstract

(57) [Summary] [PROBLEMS] To provide a barbell disc for weightlifting, which is most suitable for teaching and mastering an uplifting technique. SOLUTION: The appearance conditions such as the diameter and the thickness approved by the International Weight Lifting Federation are made as they are, and only the weight is increased, and the weight is reduced so that the technique can be repeatedly taught and the technique can be practiced repeatedly. At the same time, it improves damage resistance when dropped.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a weightlifting barbell disc, and more particularly to a practice barbell disc that is assembled to a bar to form a barbell for learning how to give a hand.

[0002]

[Technical background]

 Weightlifting is one of the sports popular among sports enthusiasts for health management as well as athletes aiming for competitions. This weightlifting is a sports competition in which a barbell of several tens to several hundreds of kilometers is offered all at once, and it requires advanced technics as well as overcoming weight. It is possible to instantly give the barbell of the desired weight for the first time by learning how to put on the waist and the timing of giving, and by interacting it with one's own physical strength. In order to learn this kind of technique, the teaching of specialized instructors such as coaches and trainers is indispensable, and learning at our own is ineffective, and above all extremely dangerous.

[0003]

[Problems to be solved by the device]

 By the way, there is no method other than repetitive teaching and repetitive practice to teach and learn such a detailed insertion technique from the insertion of the waist to the delivery timing. It is also necessary to teach them. However, in reality, since the method of teaching using a real barbell is adopted, it is difficult to perform delicate teaching and repeated practice due to weighting, which is unsuitable for teaching and learning of giving techniques. there were.

The present invention has been made in view of the above conventional circumstances, and an object of the present invention is to provide a weightlifting barbell disc which is most suitable for teaching and mastering a feeding technique.

[0005]

[Means for Solving the Problems]

 The technical means taken to achieve the above-mentioned object is to make the resin foam body whose appearance conditions such as the diameter and the thickness are the same as the genuine products. The weight lifting barbell disc of the present invention may be solid or hollow.

[0006] According to the above technical means, the appearance conditions such as diameter, thickness, etc., which are certified by the International Weight Lifting Federation, are kept as they are, and only the weight is given. Repeatable teaching and repetitive practice are possible. The weight is reduced and the damage resistance when dropped is also improved.

[0007]

[Embodiment of device]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the first embodiment, and FIG. 2 shows the second embodiment. Reference numeral A is a weightlifting barbell disc.

The weightlifting barbell disc A is made of a resin foam, more specifically, an elastic foam such as EVA, and is integral with the central boss portion a1 through which the bar 100 is inserted and both end portions of the boss portion a1. Only the disc-shaped support plates a2, a2 that are made of metal are made of metal, and are integrated with the boss part a1, the support plates a2, a2 in a state where the space between the support plates a2, a2 is filled with one half. It is molded into a solid shape with the appearance conditions, such as diameter and thickness, being as they are. That is, if the product is a barbell disc for 5 kg, the appearance conditions such as diameter and thickness are the same, and if the product is 10 kg, the appearance conditions are the same. Of course, it is also possible to color coat it to simulate a real barbell disc in terms of color.

With such a configuration, if the receiving flange 101 and the fastener 102 are sandwiched and assembled to the bar 100, other conditions except the weight, that is, the height of the bar 100 from the floor, The gripping position of the bar 100 and even the appearance are the same as those of a real barbell, and the barbell B for weightlifting constitutes a barbell B having excellent durability that is not damaged by an elastic absorbing action even when dropped.

[0010] Therefore, even if the instructor teaches how to put the waist and the timing of giving up, etc., even if the athlete or the like learns, not only repeated teaching and repeated practice are possible, but also during the giving up. It is also possible to stop and teach the posture and how to use the muscles without any difficulty, and it is possible to configure a practical practice barbell for acquiring the technique.

In the second embodiment, the weightlifting barbell disc A is hollow. With this structure, the weight can be further reduced.

[Effect of device]

 Since the present invention is made of resin foam whose appearance conditions such as diameter and thickness are genuine as described above and the weight is lighter, the other conditions are set in accordance with the standards of the International Weightlifting Federation. However, even if the instructor teaches intricately how to use the body from how to put on the waist to the timing of giving it up, even if the athlete learns, it will be possible to repeatedly teach and practice repeatedly. Not only that, you can easily pause the movement during the feeding, or you can easily delay it to teach the posture and how to use the muscles, etc., and you can configure a practical practice barbell to teach and acquire the feeding technique. . Moreover, because it has an exterior shape that conforms to the standards of the International Weightlifting Federation, but is lightweight, it is possible to limit the practice area only to a dedicated facility that has a sturdy floor structure with a shock absorbing mat laid. In addition, it is possible to practice safely and easily regardless of age or gender, not only in a general residence but also in any place where there is no special floor structure such as the garden or the outside such as the ground. Moreover, since it is made of resin foam, it has excellent impact resistance and weather resistance, and can be durable enough to be handled roughly and not damaged or damaged even when exposed to wind and rain.
