Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to an adjustable resistance buttock lift ring, elastic band unit and connector. Background Technology

[0002] A glute ring is a fitness aid specifically designed for training the glutes and leg muscles. By providing additional resistance, it helps users more efficiently activate and train their glutes and leg muscles, thereby enhancing training results. The glute ring also helps users accurately find the point of exertion, preventing compensation from other parts of the body and reducing the risk of injury. Furthermore, the resistance of the glute ring can more effectively strengthen the glutes and leg muscles, increasing training intensity. There are various ways to use a glute ring; common exercises include squats, glute bridges, lateral movements, clamshell exercises, and reverse hack squats. The glute ring has a simple, elastic, one-piece ring structure, and is typically made of high-density elastic fabric or natural latex.

[0003] Patent application number 2020231927664 discloses a non-slip buttock-lifting ring for gluteal muscle exercises, including a buttock-lifting ring body, a handle installed on the outer wall of the buttock-lifting ring body, and an adjustment device installed on the outer side of the buttock-lifting ring body. The adjustment device is used to adjust the size of the buttock-lifting ring according to the user, so that the buttock-lifting ring is more conducive to training the gluteal muscles.

[0004] However, the resistance level of a glute ring cannot be adjusted, which limits its ability to meet the needs of different training stages and individual differences. For beginners, too high a resistance level may make the movement difficult to complete; while for experienced fitness enthusiasts, a lower resistance level will not achieve the desired training effect. Therefore, the inability to adjust the resistance level of a glute ring limits its functionality and the improvement of training effectiveness. Utility Model Content

[0005] This utility model addresses the above-mentioned problems and overcomes at least one deficiency by proposing an adjustable resistance buttock-lifting ring, elastic band unit, and connector.

[0006] This application provides an adjustable resistance buttock lifter, including at least one connector and at least one set of elastic bands, wherein each set of elastic bands includes at least one elastic band unit;

[0007] The connector includes a connecting body and two first connecting portions respectively disposed on the connecting body;

[0008] The elastic band unit includes an elastic band body and two second connecting parts respectively disposed at two ends of the elastic band body;

[0009] When it includes a connector and a set of elastic bands, the two second connecting parts of the elastic band unit are detachably connected to the two first connecting parts of the connector to form a loop structure;

When the elastic band unit is made entirely of elastic material and is subjected to tension, most of the tension is borne by the rigid mounting sleeve and the rigid locking shaft, thereby mitigating or reducing the elastic deformation of the elastic mounting pin and thus improving the service life of the elastic band.

[0028] In one possible implementation, the connecting body of the connector has a leg support portion, which has an arc-shaped structure and is used to contact the leg;

[0029] The leg support has several anti-slip protrusions on the side wall that comes into contact with the leg.

[0040] The mounting hole engages with the locking shaft within the mounting slot to prevent the mounting pin from dislodging from the mounting slot.

[0041] In one possible implementation, a connector is formed at the end of the elastic band body, and the mounting pin is connected to the elastic band body through the connector.

[0042] This application also provides a connector for an adjustable resistance buttock-lifting ring, including a connecting body, a leg support, and two first connecting parts;

[0043] The two first connecting parts are respectively disposed on the outside of the connecting body;

[0044] The leg support is located on the inner side of the connecting body. The leg support has an arc-shaped structure and is used to contact the leg. The side wall of the leg support that contacts the leg has several anti-slip protrusions.

[0049] The beneficial effects of this utility model are:

[0050] (1) The buttock-lifting ring involved in this application achieves detachable installation of the elastic band by introducing a connecting component design. When it is necessary to replace the buttock-lifting ring with a different resistance value, the user can change the total resistance of the buttock-lifting ring by replacing the individual elastic bands with different resistance characteristics or by adjusting the number of individual elastic bands. This design allows the buttock-lifting ring to adapt to the needs of different training stages and individual differences, thereby enhancing its versatility and helping to improve training results.

[0051] (2) The buttock-lifting ring involved in this application has a mounting groove provided at the first connection part of the connector, and a locking shaft configured in the mounting groove. At the same time, a mounting post is provided at the end of the elastic band unit, and a mounting hole is configured on the mounting post.

The two second connecting parts 320 of the elastic band unit 30 are detachably connected to the two first connecting parts 120 of the adjacent connectors 10.

[0071] The buttock-lifting ring provided in this application features a connector 10, allowing the elastic band 20 to be detachably mounted on the connector 10. When it is necessary to replace the buttock-lifting ring with one of different resistance values, the resistance value can be changed by replacing the individual elastic bands 30 with those having different resistance values, or by increasing or decreasing the number of individual elastic bands 30. This allows the buttock-lifting ring to meet the needs of different training stages and individual differences, enhancing its versatility while also helping to improve training effectiveness.

[0072] In other embodiments, the buttock-lifting ring may include a connector 10 and a set of elastic bands 20. The two second connecting portions 320 of the elastic band unit 30 are detachably connected to the two first connecting portions 120 of the connector 10 to form a ring structure.

When only one mounting slot 121 is provided, a single elastic band 20 is provided with one elastic band unit 30. The training resistance of the buttock-lifting ring can be changed by replacing it with another elastic band body 310 with a different resistance value. When only four mounting slots 121 are provided, a single elastic band 20 is provided with four elastic band units 30. The training resistance of the buttock-lifting ring can be changed by increasing or decreasing the number of elastic band units 30.

[0077] In this embodiment, the side wall of the mounting slot 121 is provided with an opening 122;

[0078] The end of the elastic band body 310 has a connector 330. The mounting post 321 is connected to the elastic band body 310 through the connector 330. When the mounting post 321 is installed in the mounting slot 121, the connector 330 is set on the opening 122.

[0084] In this embodiment, the locking shaft 123 is disposed in the mounting slot 121 of the connecting body 110, and the mounting hole 322 is disposed on the mounting post 321 of the elastic band body 310. When the mounting post 321 is installed in the mounting slot 121, the mounting post 321 passes through the mounting hole 322 and is mounted on the locking shaft 123 to prevent the mounting post 321 from coming out of the opening 122 of the mounting slot 121.

[0085] In actual use, the locking shaft 123 can also be configured as a locking hook structure, the mounting hole 322 is configured as a locking hole that conforms to the shape of the locking hook, and the mounting pin 321 is inserted into the locking hook through the locking hole.

[0088] In actual use, the outer wall of the mounting sleeve 40 mates with the inner wall of the mounting hole 322, and the inner wall of the mounting sleeve 40 mates with the outer wall of the locking shaft 123.
