Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a resistance training device. Background Technology

[0002] With increasing public attention to health and physique, fitness has become a key way to improve physical fitness, relieve stress, and enhance appearance. At the same time, the popularization of fitness culture and its enhanced social function have prompted more people to engage in fitness activities.

[0003] Resistance training equipment is a type of fitness equipment or tool designed to enhance muscle strength, endurance, and improve physical function. These devices increase muscle load by applying resistance, thus achieving training effects; therefore, resistance training equipment is also suitable for rehabilitation training. Resistance balls combine the features of traditional yoga balls with resistance training, are made of highly elastic materials, and are available in various sizes to accommodate different heights and training needs. They utilize the instability of the ball itself and the resistance provided by external resistance bands or additional accessories to enhance core stability, improve muscle strength and endurance, while also promoting improved balance and coordination.

[0004] The application of resistance balls in pelvic floor muscle training has certain limitations. Because they tend to slip off the inside of the legs during use, this not only hinders the smooth progress of training but also affects the practicality and functionality of the resistance ball. Utility Model Content

[0005] This invention addresses the above-mentioned problems and overcomes at least one deficiency by proposing an resistance training device.

[0006] This application provides a resistance training device, including a resistance ball, a resistance band, and a connecting component;

[0007] The connecting assembly is fixed to the side wall of the resistance ball;

[0008] The resistance band is connected to the connecting component. The resistance band is arranged along the circumference of the resistance ball, and a wearing gap is formed between the resistance band and the resistance ball or between the resistance band and the connecting component. The wearing gap is for the user's limb to be inserted.

[0009] By attaching a resistance band to the outside of the resistance ball, creating a gap between the band and the ball for the user's limbs to slip through, the device prevents the ball from slipping off the inner sides of the legs or arms during training. This is particularly effective for pelvic floor muscle training, where the ball is first threaded through the resistance band onto the legs and then positioned between them, ensuring smooth training.

[0010] In one possible implementation, the connecting component includes at least one, and a single connecting component includes two first connecting portions;

[0011] The resistance band includes at least one set, and each set of resistance bands includes at least one elastic band unit. The elastic band unit includes a resistance band body and two second connecting parts respectively disposed at two ends of the resistance band body.

[0012] When including a connecting component and a set of resistance bands, the two second connecting parts of the elastic band unit are detachably connected to the two first connecting parts of the connecting component to form an annular ring sleeved on the outer periphery of the resistance ball, and the wearing gap is formed between the annular ring and the resistance ball, or an annular ring located outside the resistance ball and not sleeved on the outer periphery of the resistance ball is formed, and the wearing gap is formed inward from the annular ring.

[0013] When multiple connecting components and multiple sets of resistance bands are included, and the number of connecting components and the number of resistance band sets are equal, the multiple connecting components and multiple sets of resistance bands are arranged at intervals. The two second connecting parts of the elastic band individual of each set of resistance bands are detachably connected to the two first connecting parts of the adjacent connecting component. The wear gap is formed between each set of resistance bands and the resistance ball.

[0014] When multiple connecting components and multiple sets of resistance bands are included, and the number of connecting components is twice the number of resistance band sets, the two second connecting parts of the elastic band individual of each set of resistance bands are detachably connected to two connecting components respectively, and the wear gap is formed between each set of resistance bands and the resistance ball.

[0015] When equipped with multiple connecting components and multiple sets of resistance bands, in addition to basic hip adduction exercises via resistance balls, resistance training devices with resistance bands can also have outward expansion exercises: with hands or legs placed in the gaps formed by the resistance bands, hands or legs expand outwards to exert force, thereby achieving hip abduction or chest expansion exercises through the resistance bands.

[0016] In practical use, the number of resistance bands is preferably 2.

[0017] In one possible implementation, at least one first mounting slot is provided on the first connecting portion of the connecting component;

[0018] The second connecting part of the elastic band unit is provided with a first mounting post, which is detachably installed in the first mounting slot, so that the elastic band unit and the connecting assembly are detachably connected.

[0019] By adding a connecting component to the resistance band, the resistance band can be detachably mounted on the connecting component. When the resistance value of the resistance training device needs to be changed, it can be achieved by replacing individual elastic bands with different resistance values ​​or by increasing or decreasing the number of individual elastic bands. This allows the resistance training device to meet the needs of different training stages and individual differences, improving the versatility of the resistance training device while also helping to enhance training effectiveness.

[0020] As one possible implementation, the side wall of the first mounting slot is provided with an opening;

[0021] A connector is formed at the end of the main body of the anti-drag band, and the first mounting post is connected to the main body of the anti-drag band through the connector. When the first mounting post is installed in the first mounting slot, the connector is disposed on the opening.

[0022] In one possible implementation, the opening is located on one side of the mounting slot near the end of the resistance band body.

[0023] As one possible implementation, the first connecting part is provided with a plurality of first mounting slots, which are spaced apart along the width direction of the first connecting part.

[0024] In one possible implementation, the radial dimension of the connector is smaller than the radial dimension of the first mounting post.

[0025] In one possible implementation, at least one locking shaft is formed on the first connecting portion of the connecting assembly;

[0026] A first mounting hole is formed on the second connecting part of the elastic band unit;

[0027] The locking shaft engages with the first mounting hole, allowing the first connecting part of the connecting assembly to be detachably connected to the second connecting part of the elastic band.

[0028] In one possible implementation, the locking shaft is disposed in the first mounting slot of the connecting assembly, and the first mounting hole is disposed on the first mounting post of the resistive strip. When the first mounting post is installed in the first mounting slot, the first mounting post passes through the first mounting hole onto the locking shaft to prevent the first mounting post from coming out of the opening of the first mounting slot.

[0029] As one possible implementation, it also includes an installation sleeve, which is fitted inside the first installation hole of the first installation pin, and the first installation pin is fitted onto the locking shaft in the first installation slot through the installation sleeve;

[0030] The mounting sleeve is made of a rigid material that is not easily deformed.

[0031] The mounting sleeve can be either a PC mounting sleeve or a POM mounting sleeve. In actual use, the outer wall of the mounting sleeve mates with the inner wall of the first mounting hole, and the inner wall of the mounting sleeve mates with the outer wall of the locking shaft. 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 first elastic mounting pin and thus improving the service life of the elastic band unit.

[0032] As one possible implementation, the outer wall of the resistive ball has a first mounting lug.

[0033] The connecting assembly includes a connecting base plate and a connecting cover, the connecting cover being disposed on the connecting base plate, and two first connecting portions being formed on the connecting cover;

[0034] The connecting assembly is connected to the first mounting lug of the anti-drag ball via a connecting base plate.

[0035] In one possible implementation, the resistance ball is a PVC resistance ball, and the first mounting lug is integrally formed with the resistance ball.

[0036] As one possible implementation, the first mounting slot is located on the outside of the connecting cover.

[0037] As one possible implementation, the connection assembly further includes a connecting post;

[0038] The connecting base plate has a second mounting slot, a second mounting lug, and a through hole disposed on the side of the second mounting lug;

[0039] The connecting cover has a second mounting pin, which engages with the second mounting slot to cover the connecting base plate.

[0040] The first mounting lug has a first connecting hole, and the second mounting lug has a second connecting hole;

[0041] The first mounting lug passes through the through hole and is correspondingly disposed to the second mounting lug. The connecting post passes through the first connecting hole and the second connecting hole to fix the connecting base plate on the first mounting lug of the resistive ball.

[0042] As one possible implementation, the connecting post is interference-fitted with the first connecting hole and the second connecting hole respectively, or a fastener is provided at the end of the connecting post that protrudes from the first connecting hole and the second connecting hole, so that the connecting base plate is fixed on the first mounting lug of the resistive ball.

[0043] In one possible implementation, the second mounting lug has a wedge-shaped surface on the side away from the first mounting lug;

[0044] The inner side of the connecting cover has a limiting groove, which is adapted to the shape of the first mounting lug and the second mounting lug;

[0045] After the connecting cover is placed on the connecting base plate, the limiting slot is engaged with the first mounting lug and the second mounting lug to prevent slippage between the first mounting lug and the second mounting lug.

[0046] The inner side of the connecting cover is provided with a limiting slot to allow the connecting components to be more securely installed on the anti-drag ball.

[0047] As one possible implementation, the inner side of the connecting cover has reinforcing ribs, and the limiting groove is provided on the reinforcing ribs.

[0048] In one possible implementation, a cavity is formed inside the resistance ball, and an air vent is provided on the body wall of the resistance ball for filling the cavity with gas.

[0049] By filling the cavity with different volumes of gas, the resistance balls can have different resistance values, allowing users to adjust the training resistance value according to their actual needs and enhancing the practicality and versatility of the resistance training device.

[0050] The beneficial effects of this utility model are:

[0051] (1) A wearing gap is formed between the resistance band and the resistance ball to allow the user's limbs to pass through. When training with the resistance training device, the limbs (arms or legs) are passed through the wearing gap before the specified movement training is performed, which can prevent the resistance ball from slipping off the inside of the legs or arms.

[0052] (2) When it has multiple connecting components and multiple sets of resistance bands, the resistance training device provided in this application can also have an outward expansion exercise mode in addition to the basic hip adduction exercise through the resistance ball. The hands or legs are respectively placed in the wearing gap formed by the resistance band, and the hands or legs respectively expand outward to exert force, thereby realizing hip abduction or chest expansion exercise through the resistance band.

[0053] (3) The resistance values ​​of the resistance ball and resistance band can be adjusted separately, which makes it convenient for users to adjust the training resistance value according to actual needs, thereby enhancing the practicality and multi-functionality of the resistance training device.

[0054] (4) By setting up components such as a resistance ball with a first mounting lug, a connecting base plate with a second mounting lug, and a connecting cover with a limiting slot, the connecting components form a firm and reliable connection structure with the resistance ball and the resistance band respectively, so as to ensure the reliability of the resistance training device for hip adduction or hip abduction training.

[0067] The present invention will now be described in detail with reference to the accompanying drawings.

[0068] like Figures 1-10 As shown, this application provides a resistance training device, including a resistance ball 10, a resistance band 20, and a connecting component 30;

[0069] The connecting component 30 is fixed to the side wall of the resistance ball 10;

[0070] The resistance band 20 is connected to the connecting component 30. The resistance band 20 is arranged along the circumference of the resistance ball 10, and a wearing gap 101 is formed between the resistance band 20 and the resistance ball 10, or the resistance band 20 and the connecting component 30 form a wearing gap 101. The wearing gap 101 is used for the user's limb to be inserted.

[0071] By attaching a resistance band 20 to the outside of the resistance ball 10, and creating a wearing gap 101 between the resistance band 20 and the resistance ball 10 for the user's limbs to pass through, the user can avoid slipping the resistance ball 10 off the inside of their legs or arms when training with the resistance exercise device. Especially during pelvic floor muscle training, the resistance ball 10 is first worn through the resistance band 20 on the legs, and then placed between the legs, ensuring smooth training.

[0072] In other embodiments, the connecting component 30 includes at least one, and a single connecting component 30 includes two first connecting portions 301;

[0073] The resistance band 20 includes at least one set, and each set of resistance band 20 includes at least one elastic band unit 210. The elastic band unit 210 includes a resistance band body 211 and two second connecting parts 201 respectively disposed at two ends of the resistance band body 211.

[0074] In other embodiments, a connecting component 30 and a set of resistance bands 20 are included. The two second connecting portions 201 of the elastic band unit 210 are detachably connected to the two first connecting portions 301 of the connecting component 30, forming an annular ring sleeved on the outer periphery of the resistance ball 10. A wearing gap 101 is formed between the annular ring and the resistance ball 10. Alternatively, an annular ring is formed outside the resistance ball 10 but not sleeved on the outer periphery of the resistance ball 10. The annular ring forms a wearing gap 101 inward. In this case, the resistance band 20 only has the function of preventing slippage. The two ends of the resistance band 20 are fixed or relatively fixedly connected to the connecting component 30, respectively. Specifically, they can be glued or a slippage cover can be provided above the first mounting slot 302 of the connecting component 30 to prevent the first mounting post 212 of the resistance band 20 from slipping out from above the first mounting slot 302.

[0075] In this embodiment, it includes multiple connecting components 30 and multiple sets of resistance bands 20, and the number of connecting components 30 and the number of sets of resistance bands 20 are equal. The multiple connecting components 30 and multiple sets of resistance bands 20 are arranged at intervals. The two second connecting parts 201 of the elastic band unit 210 of each set of resistance bands 20 are detachably connected to the two first connecting parts 301 of the adjacent connecting component 30. Each set of resistance bands 20 and the resistance ball 10 form a wearing gap 101.

[0076] When multiple connecting components 30 and multiple sets of resistance bands 20 are included, and the number of connecting components 30 is twice the number of resistance bands 20, the two second connecting parts 201 of the elastic band individual 210 of each set of resistance bands 20 are detachably connected to the two connecting components 30 respectively, and a wearing gap 101 is formed between each set of resistance bands 20 and the resistance ball 10.

[0077] At this time, in addition to the basic hip adduction exercise achieved by the resistance ball 10, the resistance exercise device with the resistance band 20 can also have an outward expansion exercise mode: the hands or legs are respectively placed in the wearing gap 101 formed by the resistance band 20, and the hands or legs expand outward to exert force, thereby achieving hip abduction or chest expansion exercise through the resistance band 20.

[0078] In this embodiment, the single set of resistance bands 20 includes at least three elastic band units 210.

[0079] In this embodiment, two connecting components 30 and two sets of resistance bands 20 are included. The two connecting components 30 are connecting component A and connecting component B, and the two sets of resistance bands 20 are resistance band A and resistance band B. The two first mounting pins 212 of the elastic band unit 210 of resistance band A are respectively connected to a first mounting slot 302 of connecting component A and a first mounting slot 302 of connecting component B. The two first mounting pins 212 of the elastic band unit 210 of resistance band B are respectively connected to another first mounting slot 302 of connecting component A and another first mounting slot 302 of connecting component B. The circumference of resistance band A and resistance band B passes through the center of the resistance ball 10.

[0080] In this embodiment, the resistance ball 10 is a sphere.

[0081] In other embodiments, the resistive sphere 10 may also be an ellipsoid.

[0082] In this embodiment, at least one first mounting slot 302 is provided on the first connecting portion 301 of the connecting component 30;

[0083] The second connecting part 201 of the elastic band unit 210 is provided with a first mounting post 212. The first mounting post 212 is detachably installed in the first mounting slot 302, so that the elastic band unit 210 and the connecting assembly 30 are detachably connected.

[0084] By adding a connecting component 30 to the resistance band 20, the resistance band 20 can be detachably mounted on the connecting component 30. When the resistance value of the resistance training device needs to be changed, it can be achieved by replacing the individual elastic bands 210 with different resistance values, or by increasing or decreasing the number of individual elastic bands 210. This allows the resistance training device to meet the needs of different training stages and individual differences, improving the versatility of the resistance training device while also helping to enhance training effectiveness.

[0085] In this embodiment, the first connecting portion 301 of the connecting component 30 is provided with three first mounting slots 302.

[0086] In this embodiment, the side wall of the first mounting slot 302 is provided with an opening 303;

[0088] In this embodiment, the opening 303 is located on one side of the mounting slot near the end of the anti-resistance strip body 211.

[0089] In this embodiment, a plurality of first mounting slots 302 are provided on the first connecting portion 301, and the first mounting slots 302 are spaced apart along the width direction of the first connecting portion 301.

[0090] In this embodiment, the radial dimension of the connector 213 is smaller than the radial dimension of the first mounting post 212.

[0091] In this embodiment, at least one locking shaft 304 is formed on the first connecting portion 301 of the connecting component;

[0092] A first mounting hole 2121 is formed on the second connecting portion 201 of the elastic band unit 210;

[0093] The locking shaft 304 engages with the first mounting hole 2121, allowing the first connecting part 301 of the connecting assembly to be detachably connected to the second connecting part 201 of the elastic band.

[0094] In this embodiment, the locking shaft 304 is disposed in the first mounting slot 302 of the connecting assembly 30, and the first mounting hole 2121 is disposed on the first mounting post 212 of the resistive band 20. When the first mounting post 212 is installed in the first mounting slot 302, the first mounting post 212 passes through the first mounting hole 2121 and is mounted on the locking shaft 304 to prevent the first mounting post 212 from coming out of the opening 303 of the first mounting slot 302.

[0095] In this embodiment, an installation sleeve 220 is also included. The installation sleeve 220 is fitted inside the first installation hole 2121 of the first installation pin 212. The first installation pin 212 is fitted outside the locking shaft 304 in the first installation slot 302 through the installation sleeve 220.

[0096] Mounting sleeve 220 is a mounting sleeve made of a rigid material that is not easily deformed.

[0097] The mounting sleeve 220 can be a PC mounting sleeve, a POM mounting sleeve, or a metal mounting sleeve. In actual use, the outer wall of the mounting sleeve 220 mates with the inner wall of the first mounting hole 2121, and the inner wall of the mounting sleeve 220 mates with the outer wall of the locking shaft 304. When the elastic band unit 210 is made entirely of elastic material and is subjected to tension, most of the tension is borne by the rigid mounting sleeve 220 and the rigid locking shaft 304, thereby mitigating or reducing the elastic deformation of the elastic first mounting pin 212 and thus improving the service life of the elastic band unit 210.

[0098] In this embodiment, the outer side wall of the resistive ball 10 has a first mounting lug 110.

[0105] The connecting cover 320 has a second mounting pin 321, which engages with the second mounting slot 311 to make the connecting cover 320 cover the connecting base plate 310.
