Abstract

The utility model relates to a bar, comprising a circular bar body, the bar body comprising an installation hole formed in the center, and a plurality of hollow holes formed on the periphery of the installation hole. Through the design of the hollow holes, the light-weight bar can be relatively increased in diameter, and the height of the installation hole from the ground can be increased, which can reduce the sports injury caused by bending and exerting force when lifting weights. Good practicality.

Description

bar piece

The new model relates to a weight-lifting training equipment, in particular to a bar piece suitable for being installed on a barbell.

A general barbell consists of a grip bar and two bar pieces installed on opposite ends of the grip bar. The weight of the bar pieces is usually 1kg, 1.5kg, 2kg, 2.5kg, 5kg, 10kg, 15kg, 20kg, 25kg , during heavy training, users can choose a bar that is suitable for their muscular endurance for training. For example, a beginner or a user with insufficient muscular endurance can choose a bar with a lighter weight such as 2.5 kg or less, but due to the above The weight of the bar is proportional to the diameter. The lighter the weight, the smaller the diameter. For example, the diameter of a 2.5 kg bar is usually 160mm. When the barbell is placed on a ground, the bars stand on the ground, and the grip The axis of the bar is only 80mm away from the ground, which is quite close to the ground. Therefore, the user cannot learn the correct weight-lifting technique when the barbell is clean and snatched, and the body must bend down and sag at a large angle to grasp the barbell. Holding the bar and lifting it with force is difficult to execute, and it is easy to cause waist injury due to improper force. Therefore, how to increase the diameter of the bar to meet the competition standard bar diameter of 450mm, increase the distance between the grip and the ground, let the user learn the correct weight-lifting posture, and improve the safety of use, is one of the goals of the industry at present. one.

Therefore, the purpose of the present invention is to provide a lever sheet that can at least overcome the shortcomings of the prior art.

Therefore, the new lever blade includes a circular lever blade body, and the lever blade body includes an installation hole formed in the center and a plurality of hollow holes formed on the periphery of the installation hole.

The effect of the new type is that the bar sheet can be relatively formed with a large enough diameter under the requirement of light weight through the weight reduction design of the hollow holes, which is convenient for weightlifting and can reduce sports injuries.

Referring to FIGS. 1, 2, and 3, an embodiment of the new type of bar 3 is suitable for being installed on a barbell 1. The barbell 1 includes a left and right long grip bar 2, and two are respectively sleeved and installed on the barbell 1. The lever pieces 3 at the two opposite ends of the handle bar 2 .

The bar 3 includes a circular bar body 31 . The bar body 31 sequentially includes a hollow inner ring area 32 and a hollow area formed on the periphery of the inner ring area 32 from the inside to the outside. 33 , and an outer ring area 34 formed on the periphery of the hollow area 33 . The inner ring area 32 defines a centrally formed mounting hole 35 through which the handle bar 2 passes. The hollow area 33 has a plurality of hollow holes 36 formed on the periphery of the mounting hole 35 and communicating with two opposite sides. The hollow holes 36 are spaced apart from each other and are densely distributed in the hollow area 33. In this embodiment The distance between every two adjacent hollow holes 36 is smaller than the diameter of each hollow hole 36, and each hollow hole 36 is a honeycomb-shaped hexagonal hole, but its shape and size are not limited to this. For example, circular holes, square holes, or diamond-shaped holes may also be used. In addition, the hollow holes 36 in this embodiment are connected to two opposite sides, of course, they can also be recessed on one of the sides in design, or correspondingly or non-correspondingly recessed on these sides without being connected. , will not be described here.

The diameter D of the bar body 31 in this embodiment is 450mm, which conforms to the standard specifications of the Olympic or competitive bar, and can provide a large enough diameter, so that the distance h between the axis of the grip 2 and a ground 4 is 225mm . The inner diameter d1 of the hollow area 33 is 150 mm, and the outer diameter d2 is 410 mm. The bar body 31 is integrally formed with high-strength rubber or plastic material, which can reduce the noise generated when it collides with the ground 4 and can absorb the impact force during the collision. The weight of the bar body 31 in this embodiment is 2.5kg, of course its weight is not limited to this, it can also be other lightweight specifications, such as 2kg, 1.5kg, or 1kg, etc., and its material and structure can also be changed not limited to this, for example, its interior can also be At least one metal sheet or metal block is embedded, which can be used to increase the strength and supporting force, and can relatively reduce the thickness or change the width of the hollow area 33 .

To sum up, through the weight reduction design of the hollow holes 36, the new lever piece 3 can achieve a relatively increased diameter size under the condition of lightweight specifications, and can increase the height of the installation hole 35 relative to the ground 4 , so that the user does not need to bend down too much when the barbell 1 is clean and snatch, can maintain a safe bending angle, reduce the chance of sports injuries, and has good practicability, so it can indeed achieve the purpose of the new model.

However, the above are only examples of the present invention, which should not limit the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application for this new model and the contents of the patent specification are still within the scope of the present invention. within the scope of this new patent.
