Description

Portable Stretchers for Physical Exercise

technical field

The utility model relates to the field of sports equipment used for body building, in particular to a portable tensioner used for physical exercise.

Background technique

The tensioner is a device suitable for mass fitness exercises. The advantage of using a tensioner to exercise is that the biceps is a muscle with two muscle heads, and its main function is to bend the arms. When bending the arm, another muscle is also used, the brachialis. The brachialis muscles can only be fully exercised when doing some forearm lifting exercises, such as high-position tension machine curls or reverse high-position tension machine toys. In addition, the main muscle on the upper part of the forearm, the flexor brachii, also plays a role in the flexion of the arms, and the flexor brachii can be strengthened by bending the side of the tensioner.

The tensioner generally includes a high-quality handle and a high-strength tension spring. The length of the handle is 150 cm, the length of the handle at both ends is 30 cm, the length of the tension spring is 120 cm, and the maximum expansion is 120 cm, which can meet the fitness needs of people of different heights. .

With the development of the times, tensioners have also begun to follow the fashion path. The clumsy tensioner can only be used at home. Because it is large and heavy, it is not easy to carry or has very poor portability, so it cannot meet the requirements of people for exercising anytime and anywhere.

The portable tensioner includes a strip-shaped elastic body and two pull ring assemblies respectively arranged at both ends of the strip-shaped elastic body. Each of the pull ring assemblies Each includes a pull ring body, a cylindrical handle, and a connecting piece, the connecting piece and the cylindrical handle are respectively arranged on the inner and outer sides of the pull ring body, and the connecting piece is used to connect the pull ring body and the Long elastic body.

Further, the elongated elastic body is made of elastic material, and the elastic material is latex or rubber or silicone.

Further, the elongated elastic body is a strong elastic band or an elastic flexible hose.

Further, the elongated elastic body is a spring set, and the spring set includes a first spring, a second spring, a third spring, and a fourth spring, the first spring and the third spring have the same rotation direction, and the The second spring and the fourth spring are opposite to the first spring.

Further, the first spring and the third spring are left-handed springs, and the second spring and the fourth spring are right-handed springs; or, the second spring and the fourth spring are left-handed springs, and the first spring And the third spring is a right-handed spring.

Further, the pull ring body is a rectangular ring structure, the connecting piece and the cylinder handle are respectively sleeved on the inner and outer sides of the rectangular ring structure, and the upper and lower sides of the rectangular ring structure Protruding extensions are respectively provided at both ends.

Further, the cylindrical handle is made of waterproof material or non-slip material or both waterproof and non-slip material.

Further, the cylindrical handle is provided with anti-slip grooves or anti-slip embossments.

The portable tensioner used for physical exercise of the utility model has simple structure, low cost, can keep fit, and is small in size, easy to be rolled up and carried around, and can be stretched and exercised after work or study, so it can satisfy people at any time. Anywhere exercise requirements.

detailed description

In order to facilitate the understanding of the present invention, the utility model will be described more comprehensively and in detail below in conjunction with the accompanying drawings and preferred embodiments, but the protection scope of the utility model is not limited to the following specific embodiments.

For ease of description, it is stipulated here that the inner side of the tab body 2 refers to the side of the tab body 2 close to the elongated elastic body 1, and correspondingly, the outer side of the tab body 2 refers to the side of the tab body 2 away from the elongated elastic body 1. On one side of the elastic body 1, when the portable tensioner provided by the utility model is placed as shown in Figure 1, the directions of "up" and "down" appearing in the following text are the same as the directions of "up" and "down" of accompanying drawing 1 respectively. One-to-one correspondence or corresponding agreement.

As shown in Figure 1 , a portable tensioner for physical exercise, the portable tensioner for physical exercise includes a strip-shaped elastic body 1, and two pull ring assemblies respectively arranged at both ends of the strip-shaped elastic body 1, Each pull ring assembly includes a pull ring body 2, a cylindrical handle 3, and a connecting piece 4. The connecting piece 4 and the cylindrical handle 3 are respectively arranged on the inner and outer sides of the pull ring body 2, wherein the connecting piece 4 is used to connect The pull ring body 2 and the elongated elastic body 1.

The portable tensioner with the above structure is simple in structure, low in cost, capable of keeping fit, small in size, easy to roll up and carry around, can stretch and exercise the body after work or study, and thus can meet people's requirements for exercising anytime and anywhere.

Specifically, the elongated elastic body 1 is made of elastic body material, which can be latex, rubber, or silica gel. Thus, the elasticity of the elongated elastic body 1 can be used to exercise the arms.

Specifically, the elongated elastic body 1 can be a strong elastic band, or an elastic flexible hose. In a specific embodiment, the elongated elastic body 1 is a spring set, and the spring set includes a first spring, a second spring, a third spring, and a fourth spring arranged in sequence, wherein the first spring and the third spring rotate The direction of rotation of the second spring and the fourth spring is opposite to that of the first spring. More specifically, the first spring and the third spring are left-handed springs, and the second spring and the fourth spring are right-handed springs. Of course, it is also possible that the second spring and the fourth spring are left-handed springs, and the first spring and the third spring are right-handed springs. In this example, the four springs are just symmetrically arranged, and because the directions of rotation between adjacent springs are different, the springs will not be entangled with each other when the tensioner is folded.

Preferably, the pull ring body 2 is a rectangular ring structure, the connector 4 and the cylindrical handle 3 are respectively sleeved on the inner and outer sides of the rectangular ring structure, and the two ends of the upper and lower sides of the rectangular ring structure are respectively set There is a protruding extension 5 . With this arrangement, it is convenient to wrap the elongated elastic body 1 on the ring assembly, and at the same time, due to the limiting effect of the protruding extension part 5, the elongated elastic body 1 will not slip out from the upper and lower sides of the pull ring assembly , it is convenient to carry the tensioner better.

Preferably, the cylindrical handle 3 can be made of waterproof material or anti-slip material or a material that is both waterproof and anti-slip. Meanwhile, the cylindrical handle 3 is provided with anti-slip grooves or anti-slip embossed lines to prevent hands from leaving the handle.

The above-mentioned embodiments only express several implementation modes of the utility model, and the description thereof is relatively specific and detailed, but it should not be interpreted as a limitation on the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
