Description

CROSS-REFERENCE TO RELATED PATENT APPLICATION

This application claims the benefit of priorities to Taiwan Patent Applications No. 112138651, filed on Oct. 11, 2023, and No. 112208080, filed on Aug. 1, 2023. The entire content of the above identified applications is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to a portable exercise apparatus, and more particularly to a multi-functional portable exercise apparatus that has a foldable function and that is easy to accommodate and transport after being folded.

BACKGROUND OF THE DISCLOSURE

A conventional training bench includes a plurality of dumbbells of various weights arranged thereon. The conventional training bench is bulky and heavy, so that the training bench is very difficult to be transported. An elastic rope is provided with the training bench and can be directly tied to four corners of the training bench. However, a force of the elastic rope cannot be controlled and cannot be freely combined for weight training exercises (e.g., with barbells), so that the elastic rope only has a single training function.

Furthermore, a rowing machine is another type of fitness equipment for full-body exercise. Users can perform arm stretching, body stretching, and leg flexion on the rowing machine. Due to a resistance source of the rowing machine being generally a water resistance or an air resistance, a size of the rowing machine is relatively large. The rowing machine having a foldable function that is currently available on the market is only provided in a few models for reducing the size thereof when being folded.

Therefore, if a user wants to use the above fitness equipment at home, it will inevitably take up a considerable amount of indoor space. Although the conventional rowing machine can be folded to be used as the training bench, the conventional rowing machine lacks accessories such as the dumbbell and the elastic rope. Accordingly, the conventional rowing machine is only used for simple body exercises and has limitations for targeted strength training.

SUMMARY OF THE DISCLOSURE

In response to the above-referenced technical inadequacies, the present disclosure provides a portable exercise apparatus that has a function of a rowing machine and that can be easily accommodated and transported after being folded.

In response to the above-referenced technical inadequacies, the present disclosure further provides a portable exercise apparatus that can be folded to perform the weight training exercise for all four limbs, thereby achieving a variety of strength training functions.

To address these challenges, the portable exercise apparatus includes a first main body, a second main body, a seat, a pedal, and at least one resistance unit. The first main body has at least one receiving space. The second main body is connected to the first main body. Both main bodies are foldable relative to each other so as to be in a folded mode or an expanded mode. The seat is slidably disposed on the first main body when expanded. The pedal is disposed between the first main body and the second main body. The pedal is in a slanted position when the first main body and the second main body are in the expanded mode. The at least one resistance unit has a resistance source and is disposed on at least one of the first main body, the second main body, and the pedal. When folded, the first main body and the second main body jointly have a box shape, so that at least one of the seat and the pedal is located between the first main body and the second main body. Additionally, the resistance source of the at least one resistance unit is arranged in the at least one receiving space and is connected to at least one pulling member.

Therefore, in the portable exercise apparatus provided by the present disclosure, the portable exercise apparatus allows a user to simulate rowing movements and has a foldable function. In addition, when the first main body and the second main body are folded to jointly have a box shape, at least one of the seat and the pedal is located between the first main body and the second main body, such that the first main body and the second main body have a flat and aesthetic appearance when folded, thereby allowing the user to easily store and transport the equipment.

Additionally, when both of the main bodies are folded, the user can utilize the resistance source and the pulling member placed within the receiving space for comprehensive weight training of all four limbs.

These and other aspects of the present disclosure will become apparent from the following description of the embodiment taken in conjunction with the following drawings and their captions, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.

Referring to FIG. 1 and FIG. 4, the present disclosure provides a portable exercise apparatus. The portable exercise apparatus includes a first main body 1, a second main body 2, a seat 3, a pedal 4, and at least two resistance units 5.

The first main body 1 and the second main body 2 are connected. Both of the main bodies are pivotally connected through a rotation shaft 6, and the first main body 1 and the second main body 2 are foldable relative to each other so as to be in a folded mode or an expanded mode. When the first main body 1 and second main body 2 are in the folded mode, the first main body 1 and the second main body 2 jointly have a box shape (as shown in FIG. 3 and FIG. 4) or a cube shape, so that the seat 3 and the pedal 4 are located and received between the first main body 1 and the second main body 2.

In the present embodiment, the first main body 1 has a first panel 11 and two sideboards 12 that are connected to and uprightly disposed on two opposite sides of the first panel 11, and an accommodating space 13 is formed among the first panel 11 and the two sideboards 12. When the first main body 1 and the second main body 2 are in the folded mode, the second main body 2 is accommodated in the accommodating space 13, so that the first main body 1 and the second main body 2 jointly have the box shape for reducing the size of the portable exercise apparatus, and the seat 3 and the pedal 4 are located between the first main body 1 and the second main body 2.

The first main body 1 has at least one receiving space 16 that is exposed from the first main body 1. The receiving space 16 is preferably arranged on an edge of the first main body 1. A quantity of the receiving space 16 can be one, two, three, or four, but is not limited thereto. In the present embodiment, the quantity of the receiving space 16 is four, each of two sides of the first main body 1 has the two receiving spaces 16 that are arranged on two opposite ends thereof. Specifically, the receiving spaces 16 are respectively arranged at four corners of the first main body 1, so that there is a larger distance between the two receiving spaces 16 on a same side of the first main body 1. In the present embodiment, the rotation shaft 6 is a hollow cylinder, and the receiving space 16 can be formed in the rotation shaft 6 (as shown in FIG. 5), so that the rotation shaft 6 further has an accommodating function that can accommodate a resistance source 51.

In the present embodiment, the first main body 1 has multiple recessed spaces 18 recessed in the two sides thereof, two outer surfaces of each of the receiving spaces 16 are respectively formed with two of the recessed spaces 18, and each of the receiving spaces 16 and the corresponding two recessed spaces 18 are in spatial communication with each other, so that fingers can easily reach into the recessed spaces 18 to remove or insert the resistance source 51.

In the present embodiment, the second main body 2 has a second panel 22 (as shown in FIG. 3), and when the first main body 1 and second main body 2 are in the folded mode, the second panel 22 covers the accommodating space 13, so that the first main body 1 and the second main body 2 jointly have a complete box structure. Specifically, one end of the second main body 2 is disposed on a first handle (i.e., a handle) 23, one end of the first main body 1 is fitted with two wheels 15, which are rotatably and pivotally connected to the first main body 1. When the first main body 1 and the second main body 2 of the embodiment are not in the expanded mode, an accommodating state of the first main body 1 and the second main body 2 is an upright cube that has the first handle 23 arranged on a top thereof and the wheels 15 are arranged at the bottom thereof for being easily accommodated and transported (as shown in FIG. 3). The first handle 23 can be disposed on the one end of the first main body 1, and the two wheels 15 can be disposed on the one end of the second main body 2.

Additionally, a locking mechanism 17 can be disposed between the first main body 1 and the second main body 2 (as shown in FIG. 1), and the locking mechanism 17 can be an insertion pin, a hook, or various locking structures. This allows the first main body 1 and second main body 2 to lock together using the locking mechanism 17 when they are folded. Furthermore, a cushion 10 (as shown in FIG. 4) is attached onto an outside of the first panel 11 or the second panel 22, so that a user can be more comfortable in lying or kneeling positions when playing tension training. The one end of the first main body 1 or the second main body 2 having the two wheels 15 further has a second handle (i.e., a handle) 19 (as shown in FIG. 1) that is used for expanding or folding the portable exercise apparatus.

When the portable exercise apparatus is in the folded mode, it can be laid flat on the floor, or it can also be uprightly placed by using a top end thereof to abut against a wall and using a bottom end thereof to be cooperated with a base 20 (as shown in FIG. 6 and FIG. 7). The first main body 1 and the second main body 2 are configured to be uprightly disposed on the base 20. The base 20 has a block structure 201. The block structure 201 and the second handle 19 are engaged with each other, and a length of the block structure 201 is less than or equal to a length of the second handle 19. The portable exercise apparatus can be stably and uprightly placed and abut against the wall through the engagement between the block structure 201 and the second handle 19.

Under ordinary circumstances, the seat 3 can be accommodated in the second main body 2, and a containment space 21 (as shown in FIG. 1) can be formed in the second main body 2 for accommodating the seat 3. When the portable exercise apparatus needs to be expanded, the first main body 1 and the second main body 2 can be expanded first, the seat 3 can then be placed onto the first main body 1 by being taken out from the second main body 2, so that the first main body 1 and the second main body 2 are in the expanded mode, and a bottom of the seat 3 has a plurality of rollers 31 that can roll independently or that can be provided in multiple pairs each assembled to left and right ends of one connecting rod, the rollers 31 being slidable on the two sideboards 12 of the first main body 1. Due to a sliding technology being a conventional technology, a sliding structure of the present disclosure does not have limitations, and the embodiment is not described for brevity's sake.

The pedal 4 is disposed between the first main body 1 and the second main body 2. When the first main body 1 and the second main body 2 are in the expanded mode, the pedal 4 can be rotated to a slanting position in a use state (as shown in FIG. 1 and FIG. 2), so that the user's feet can be placed on and supported by the pedal 4 during training.

The two resistance units 5 are disposed on at least one of the first main body 1, the second main body 2, and the pedal 4. Each of the two resistance units 5 has a resistance source 51, at least one pull rope 511, and other components. The resistance source 51 can be a tension motor or other components for providing a resistance force. When the first main body 1 and second main body 2 are in the folded mode, the resistance sources 51 of the two resistance units 5 are respectively accommodated in the two receiving spaces 16. When the portable exercise apparatus needs to utilize the function of rowing machine, one of the resistance sources 51 can be taken out from the corresponding receiving space 16 for transforming into the rowing machine structure. The resistance sources 51 can be combined with at least one pulling member 52 that includes a pull-up bar, an exercise bar, and fitness rings, etc., but the present disclosure is not limited thereto.

One end of the pedal 4 is pivotally connected to the second main body 2, and the pedal 4 is rotatable relative to the second main body 2. Another end of the pedal 4 is pivotally connected to a pulley plate 7. A pulley 71 is rotatably disposed on the pulley plate 7, and the pulley plate 7 is rotatable relative to the pedal 4, so that the pedal 4 and the pulley plate 7 can be stacked on an inside of the second main body 2 or can be rotated and expanded according to the requirements. The second main body 2 is pivotally connected to a supporting frame 8. The pedal 4, the pulley plate 7, and the supporting frame 8 can be rotated and expanded for enabling the supporting frame 8 to support the pulley plate 7 and the pedal 4 and enabling the resistance source 51 to be disposed on the supporting frame 8 (as shown in FIG. 2). Furthermore, the pulley plate 7 can also press the resistance source 51, and the supporting frame 8 and the pulley plate 7 are fixed through at least one insertion pin 9 inserted therein, so that the pedal 4, the pulley plate 7, and the supporting frame 8 can be fixed. The pull rope 511 of the resistance source 51 can be smoothly pulled through the pulley 71, such that after the pull rope 511 is pulled out and crosses the pulley 71, a moving direction of the pull rope 511 is changed, thereby completing the assembly of the rowing machine (as shown in FIG. 1 and FIG. 2) for enabling an operation of the rowing machine to begin.

As shown in FIG. 8 and FIG. 9, when the first main body 1 and the second main body 2 are in the folded mode (i.e., an accommodating mode), the user can utilize the resistance source 51 and the pulling member 52 placed in the receiving space 16 to play tension and weight training for all four limbs.

When the two resistance units 5 are in use, the two resistance units 5 can be operated synchronously and can perform resistance compensation. Under many circumstances, the user may simultaneously use the resistance units 5. For example, when the resistance units 5 are operated in a simulated barbell mode, they need to provide the resistance force at the left and right sides of the user. If the two resistance units 5 are not synchronized, the user may feel that force from the left and right sides is unbalanced. In the present embodiment, a synchronous network including the resistance source 51 of the resistance units 51 and the pulling member 52 can be established so as to enable the resistance units 5 to be operated synchronously. When the pulling member 52 (e.g., the exercise bar, the pull-up bar, and the fitness rings) detects the imbalance of the resistance units 51, the pulling member 52 can actively compensate for the output of the resistance units 51, thereby reducing the sensation of force unbalance.

As shown in FIG. 10 the fixing frame 40 can be pivotally connected to the pulley plate 7 or the supporting frame 8 of the present disclosure. The fixing frame 40 is rotatable relative to the pulley plate 7 or the supporting frame 8, and a telescopic frame 50 is disposed on the fixing frame 40. When the fixing frame 40 is rotated upward to a predetermined position, the fixing frame 40 is configured to hold an electronic device 100 such as a smartphone or a tablet. When the fixing frame 40 is rotated upward to a predetermined position, the telescopic frame 50 can be used to clamp and fix the electronic device 100 such as a smartphone or a tablet. The electronic device 100 can display information or a course of the user exercise in a wireless communication manner or other manners.
