The present invention relates to a training device, in particular to a fitness device with an adjustable support pad.

Street fitness uses one's own weight and objects that can be touched in daily life for freehand training, such as the horizontal bar in the park, the floor, ladder racks, etc. Common fitness movements include human national flag, Russian push-up, front horizontal and violent push-up.

Since these bodyweight training movements require strong muscle strength to overcome one's own body weight and excellent physical fitness to complete, these movements are highly difficult for fitness enthusiasts and it is quite difficult to learn and complete fitness training.

Therefore, the object of the present invention is to provide a fitness device that can assist fitness and has an adjustable support pad.

Therefore, the fitness device with adjustable support pad of the present invention is suitable for being installed on a base. The fitness device with adjustable support pad comprises a frame unit, a power unit, a support pad unit, and at least one handle unit.

The rack unit is suitable for being installed on the base along a height direction. The power-assisting unit is arranged on the rack unit and is used to provide an upward supporting force in the height direction. The support pad unit is connected to the power-assisting unit and is driven by the power-assisting unit to move along the height direction. The support pad unit includes a connecting frame connected to the power-assisting unit, a slide seat that can slide relative to the connecting frame in an adjustable manner along a length direction substantially perpendicular to the height direction, and a support pad arranged on the slide seat and moving with the slide seat. The support pad has a predetermined length in the length direction and can be abutted by a user's trunk. The handle unit is arranged on the rack unit or the base and is used for the user to hold it with his hand.

The utility model has the following effects: the support pad is used for the user's trunk to lean against, and the upward support force provided by the power-assisting unit can drive the support pad to rise, so as to assist the user to complete the fitness movement. Moreover, the slide seat can slide relative to the connecting frame, so the position of the support pad can be adjusted according to the height of the user, and the applicability is good.

Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

1 to 3 , a first embodiment of the fitness device with an adjustable support pad of the present invention is suitable for installation on a base 1. The fitness device with an adjustable support pad comprises a frame unit 2, a power unit 3, a support pad unit 4, and two handle units 5 (due to the viewing angle, only one handle unit 5 is seen in the figure).

The rack unit 2 is suitable for being installed on the base 1 along a height direction Z. The base 1 can be an elastic pad, a ground or a plate. The rack unit 2 of this embodiment includes a plurality of connecting posts 21 installed on the base 1 and extending along a height direction Z, an upper seat 22 fixed to the top of the connecting posts 21, and a back plate 23 connected to the upper seat 22 and extending along the height direction Z.

Referring to FIGS. 2 to 4 , the boosting unit 3 is disposed on the frame unit 2 and is used to provide an upward supporting force in the height direction Z. The boosting unit 3 of the present embodiment includes a pulley 31 rotatably fixed to the upper seat 22 of the frame unit 2, a plurality of counterweights 32 located below the pulley 31, and a connecting rope 33 used to drive the counterweights 32 to move along the height direction Z. The connecting rope 33 has a first end 331 and a second end 332 opposite to each other. The first end 331 is fixedly connected to the support pad unit 4. The second end 332 is used to connect the counterweights 32. The user can change the magnitude of the upward supporting force by selecting the number of the counterweights 32 to be driven. The upward supporting force is equal to the weight of the weight blocks 32 being driven.

The support pad unit 4 is connected to the linking rope 33 of the assisting unit 3 and can be driven by the assisting unit 3 to move along the height direction Z. The support pad unit 4 includes a connecting frame 41 connected to the first end 331 of the linking rope 33, a slide seat 42 that can slide relative to the connecting frame 41 along a length direction L that is substantially perpendicular to the height direction Z, and a support pad 43 that is arranged on the slide seat 42 and moves with the slide seat 42. The support pad 43 of the present embodiment is spaced apart from the assisting unit 3 in a width direction W that is substantially perpendicular to the height direction Z and the length direction L. In some variations, the assisting unit 3 can also be turned 90 degrees and spaced apart from the support pad 43 in the length direction L. The support pad 43 has a predetermined length in the length direction L so as to be able to be supported by a user's trunk.

Specifically, the connecting frame 41 includes an L-shaped connecting rod 411 connected to the power-assisting unit 3, and a fixed rail 412 connected to the connecting rod 411 and extending along the length direction L. The fixed rail 412 has a plurality of limit holes 413 spaced apart in the length direction L, and two limit grooves 414 spaced apart in the width direction W. The slide 42 has a moving member 421 slidably disposed on the fixed rail 412, and a latch 422 passing through the moving member 421 and selectively positioned in one of the limit holes 413. The moving member 421 has two limit rails 423 slidably engaged with the limit grooves 414, respectively. The limit rails 423 of this embodiment are hooks. In other variations, the connecting frame 41 and the sliding seat 42 can be replaced by existing equivalent components as long as the two can slide relative to each other and be positioned.

The support pad 43 can be an elastic pad or a soft pad.

Since the slide seat 42 can slide relative to the connecting frame 41, the position of the supporting pad 43 in the length direction L can be adjusted according to the height of the user, and the applicability is good.

This embodiment utilizes the upward supporting force of the power-assisting unit 3 to drive the supporting pad unit 4 to move upward, so as to assist in lifting the user in the height direction Z.

Referring to FIG. 2 , FIG. 4 , and FIG. 5 ( 1 ) and ( 2 ), the grip units 5 are located below the support pad 43 in the height direction Z, and are spaced apart on the base 1 in the width direction W. The grip units 5 are used for the user to hold them. Each of the grip units 5 includes a fixed base 51 fixed on the base 1, a movable base 52 mounted on the fixed base 51 and capable of moving relative to the fixed base 51, and a grip assembly 53 disposed on the movable base 52 and moving with the movable base 52.

In this embodiment, the fixed seat 51 is substantially in the shape of a cuboid and has a track 511 extending along the width direction W and a plurality of positioning holes 512 spaced apart on the bottom surface of the track 511. The movable seat 52 is substantially in the shape of a disk and has a plurality of adjustment holes 521 spaced apart and arranged in a fan shape.

The grip assembly 53 comprises a grip seat 531 rotatably mounted on the mobile seat 52, a grip 532 fixed to the grip seat 531, a positioning pin 533 passing through the grip seat 531 and selectively positioned in one of the adjustment holes 521, and a spring pin 534 passing through the grip seat 531 and the mobile seat 52 and selectively positioned in one of the positioning holes 512. The grip seat 531 can rotate relative to the mobile seat 52 with the spring pin 534 as the rotation center, and cooperate with the positioning pin 533 to position the grip seat 531 in one of the adjustment holes 521, thereby changing the angle of the grip 532.

As shown in FIG. 4 and FIG. 5 (1), the handles 532 are perpendicular to the track 511, and the handles 532 can be used by the user to adopt a standard shoulder-width grip. As shown in FIG. 5 (2), the handles 532 are rotated 90 degrees, and the handles 532 can be used by the user to adopt a reverse grip with a 1.5-times shoulder-width grip. As shown in FIG. 6 (1), the handles 532 are rotated 36 degrees and moved outward for a distance, and the handles 532 can be used by the user to adopt an outward eight grip with a 2-times shoulder-width grip. As shown in FIG6(2), the handles 532 rotate 18 degrees and move to the outermost positioning hole 512 of the track 511. At this time, the handles 532 allow the user to adopt an outward-facing eight-grip posture (airplane style) with a grip distance of 3 times the shoulder width.

This embodiment can change the distance between the handles 532 or the distance between the handles 532 and the support pad 43 in the length direction L by moving the handle sets 53 on the rails 511 of the fixing bases 51, so as to accommodate users of different heights and different arm lengths, and thus has a wide range of applications. In addition, the angles of the handles 532, the arm opening angle and the hand gripping posture can be changed by rotating the handle sets 53, so as to train different muscle groups of the arm. In some variations, the handle unit 5 may not have the function of adjusting the position or angle of the handles 532.

Referring to FIG. 1 and FIG. 2 , when operating the present embodiment to assist in the Russian push-up exercise, the user's starting position is as shown in FIG. 1 , and the user lies down on the support pad 43, uses his own weight to press down the support pad 43, and holds the handles 532 with both hands and bends his arms, with his toes touching the base 1. At this time, the counterweights 32 (whose total weight is usually less than the user's body weight) connected to the linkage rope 33 are driven up because the support pad 43 descends. Next, as shown in FIG. 2 , the user exerts force with both hands, straightens the arms and props up the body horizontally, with both feet off the ground at the same time. At this time, the counterweight blocks 32 connected to the linkage rope 33 provide the upward supporting force, so that the support pad unit 4 rises to assist the user in lifting the body in the height direction Z. Therefore, the user can complete the Russian push-up with a force less than his own body weight (i.e., the user's body weight minus the weight of the counterweight blocks 32), which is not only more labor-saving, but also the user's trunk is supported by the support pad 43, and the center of gravity is more stable, so the user can continue to maintain the Russian push-up action, and the fitness effect is better.

It should be noted that since the upward supporting force is equal to the weight of the weight blocks 32 being driven, that is, when the user selects a larger number of weight blocks 32, the greater the upward supporting force, the easier it is to complete the Russian push-up. If the fitness effect is to be enhanced, the number of weight blocks 32 can be reduced.

Referring to FIG. 7 , in a variation, the support pad 43 has a pad body 431 and a pillow 432 that can be flipped and arranged at one end of the pad body 431. The pad body 431 has a predetermined length for the user's trunk to lean against. The pillow 432 is for the user's chest to press against so as to perform the training of straightening up and arching the back. The pillow 432 is connected to the pad body 431 by sewing a piece of cloth, so that when not in use, the pillow 432 can be flipped to the front side of the pad body 431.

Referring to FIG. 8 , a second embodiment of the present invention is similar to the first embodiment, except that:

The fitness device with an adjustable support pad includes a handle unit 5'. The handle unit 5' is fixed to the back plate 23 of the frame unit 2 and is higher than the support pad unit 4 in the height direction Z. The handle unit 5' has a handle 532' connected to the back plate 23 of the frame unit 2 and extending along the width direction W. Specifically, the handle 532' is a metal long rod.

When operating this embodiment to assist in front horizontal fitness movements, the user lies on the support pad 43 in a supine position, holds the handles 532' with both hands and straightens the arms. The counterweight blocks 32 connected to the linkage rope 33 provide the upward supporting force, so that the support pad unit 4 can assist in lifting the user's body in the height direction Z. Therefore, the user can complete the front horizontal movement with a force less than his own body weight, which is more labor-saving. In addition, the user's trunk is supported by the support pad 43, and the center of gravity is more stable, so the user can continue to maintain the front horizontal movement, and the fitness effect is better.

In summary, the fitness device of the present invention has an adjustable support pad, and the support pad 43 is used for the user's trunk to lean against, and the upward support force provided by the power-assisting unit 3 can drive the support pad 43 to rise, so as to assist the user to complete fitness movements. In addition, the slide seat 42 of the present invention can slide relative to the connecting frame 41, so the position of the support pad 43 in the length direction L can be adjusted according to the height of the user, and the applicability is good, so the purpose of the present invention can be achieved.

However, the above is only an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
