Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to an elliptical machine with an extended stride. Background Technology

[0002] Elliptical trainers, also known as space walkers, are popular among users and professionals alike as they are highly effective for cardiovascular exercise. Their incline design, adjustable resistance, choreographed exercise patterns, and ability to specifically target lower limb muscles make them a common piece of exercise equipment in professional gyms and home living rooms.

[0003] Existing elliptical trainers all use a swing arm to drive the foot pedals to swing in an elliptical trajectory. The foot pedals, which are fixed to the foot pedals, allow the user's feet to move along this trajectory. However, since the foot pedal positions are fixed, the stride length is also fixed during use. This means that the stride length is limited by the movement trajectory of the foot pedals. Therefore, existing elliptical trainers are basically fixed in stride length after leaving the factory, resulting in a single product use and a lack of flexibility. Utility Model Content

[0004] The purpose of this invention is to provide an elliptical trainer with an extended stride length. The foot pedal slide not only moves elliptically with the foot pedal but can also slide relative to the foot pedal, thereby adding a back-and-forth sliding function within the inherent movement trajectory, thus increasing the stride length and making the product more flexible to use.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] An elliptical trainer with an extended stride length includes an elliptical trainer body, a flywheel assembly, a left swing assembly, and a right swing assembly;

[0007] The flywheel assembly is mounted on the elliptical machine body, and the left swing assembly and the right swing assembly are respectively hinged to both sides of the elliptical machine body and can swing relative to the elliptical machine body.

[0008] The left swing assembly and the right swing assembly include at least a rocker arm, a foot pedal, and a foot slide. The foot slide is slidably mounted on the foot pedal. One end of the foot pedal is hinged to the rocker arm, and the other end is connected to the flywheel assembly. The rocker arm swings to drive the foot pedal relative to the main body of the elliptical machine, and the foot slide can slide back and forth on the foot pedal.

[0009] As described above, the elliptical machine with an extended stride stroke further includes a linkage rod for the left and right swing components. One end of the linkage rod is hinged to the rocker arm, and the other end is hinged to the foot pedal slide. When the rocker arm swings, the linkage rod can drive the foot pedal slide to slide back and forth on the foot pedal arm.

[0010] As described above, an elliptical trainer with an extended stride travel includes a foot pedal rod comprising a connecting rod and a guide rail seat. One end of the connecting rod is hinged to the rocker arm. The front end of the guide rail seat is connected to the connecting rod, and a connecting part is provided near the end of the guide rail seat. The connecting part is connected to the flywheel assembly, and the foot pedal slide is slidably disposed on the guide rail seat.

[0011] As described above, an elliptical machine with an extended stride stroke includes a flywheel assembly comprising a rear wheel, on both sides of which are rotating frames that rotate with the rear wheel. The rotating frames are provided with multiple docking positions, and the connecting part of the guide rail seat is connected to the docking positions.

[0012] As described above, in an elliptical trainer with an extended stride travel, the foot pedal slide has a connecting frame extending to the underside of the guide rail, and one end of the linkage rod is hinged to the connecting frame.

[0013] As described above, an elliptical trainer with an extended stride travel includes a foot pedal slide body and a foot pedal. The slide body is slidably mounted on the guide rail seat, the foot pedal is connected to the upper side of the slide body, and the connecting frame is connected to both sides of the slide body and extends to the lower side of the guide rail seat.

[0014] As described above, an elliptical machine with an extended stride stroke has grooves on both sides of the guide rail base, and the slide body has side plates extending downward to the side grooves on both sides. The inner side of the side plates is provided with a sliding body that extends into the groove.

[0015] As described above, an elliptical machine with an extended stride stroke includes a base and slide rails connected to both sides of the base, with the slide grooves provided on the slide rails.

[0016] As described above, an elliptical machine with an extended stride travel has a rocker arm that is hinged to the main body of the elliptical machine. The rocker arm is located above the hinge and below the hinge. One end of the linkage rod is hinged to the lower side of the upright. The upright also has a hinge member that is hinged to the foot pedal.

[0017] As described above, in an elliptical machine with an extended stride stroke, the upright is an adjustable length upright.

[0018] In summary, the advantages of this utility model over the prior art are:

[0019] This invention provides an elliptical trainer with an extended stride travel. It uses a rocker arm and flywheel assembly to drive the foot pedals in an elliptical trajectory when the rocker arm swings. The foot pedal slides on the foot pedals also move in an elliptical trajectory. At the same time, the foot pedal slides can slide relative to the foot pedals, thereby adding a back-and-forth sliding function for the user within the original movement trajectory, increasing the stride travel and making the product more flexible and comfortable to use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 8As shown, this utility model provides an elliptical machine with an extended stride stroke, including an elliptical machine body 1, a flywheel assembly 2, a left swing assembly 3, and a right swing assembly 4; the flywheel assembly 2 is disposed on the elliptical machine body 1, and the left swing assembly 3 and the right swing assembly 4 are respectively hinged to both sides of the elliptical machine body 1 and can swing relative to the elliptical machine body 1; the left swing assembly 3 and the right swing assembly 4 include at least a rocker arm 31, a foot pedal 32, and a foot slide 34, the foot slide 34 is slidably disposed on the foot pedal 32, one end of the foot pedal 32 is hinged to the rocker arm 31, and the other end is connected to the flywheel assembly 2, the rocker arm 31 swings to drive the foot pedal 32 to move relative to the elliptical machine body 1, and the foot slide 34 can slide back and forth on the foot pedal 32. It works in conjunction with the flywheel assembly 2 via the rocker arm 31. When the rocker arm 31 swings, it drives the foot pedal 32 to move in an elliptical trajectory. The foot pedal slide 34 set on the foot pedal 32 also moves in an elliptical trajectory. At the same time, the foot pedal slide 34 can slide relative to the foot pedal 32, thereby adding a function for the user to slide back and forth within the inherent movement trajectory, increasing the stride length when using it, and making the product more flexible and comfortable to use.

[0031] In addition, in this embodiment of the invention, the left swing assembly 3 and the right swing assembly 4 further include a linkage rod 33. One end of the linkage rod 33 is hinged to the rocker arm 31, and the other end is hinged to the foot pedal slide 34. When the rocker arm 31 swings, the linkage rod 33 drives the foot pedal slide 34 to slide back and forth on the foot pedal 32. The foot pedal slide 34 is not slidably mounted on the foot pedal 32 independently. It is connected to the linkage rod 33 to form a linkage movement driven by the rocker arm 31. That is, the foot pedal slide 34 makes a regular reciprocating motion on the foot pedal 32 as the rocker arm 31 swings, thus making the product more reasonable to use.

[0032] Furthermore, in this embodiment of the present invention, the specific structure of the foot pedal 32 is as follows: the foot pedal 32 includes a connecting rod 321 and a guide rail seat 322. One end of the connecting rod 321 is hinged to the rocker arm 31. The front end of the guide rail seat 322 is connected to the connecting rod 321, and a connecting part 3221 is provided near the end of the guide rail seat 322. The connecting part 3221 is connected to the flywheel assembly 2. The foot pedal slide 34 is slidably disposed on the guide rail seat 322. This changes the traditional rod frame structure by adding a guide rail seat 322 part that cooperates with the foot pedal slide 34. This allows the foot pedal slide 34 to not only move elliptically but also slide back and forth against it, thereby changing the relatively fixed movement mode of the traditional foot pedal. This increases the user's stride and changes the range of motion. Moreover, this structure does not require adjustment before use, making it more flexible and convenient to use.

[0033] In this design, the flywheel assembly 2 includes a rear rotor 21, with rotating frames 22 on both sides of the rear rotor 21 that rotate with it. Each rotating frame 22 has multiple mating positions, and the connecting portion 3221 of the guide rail seat 322 is connected to these mating positions. Specifically, the multiple mating positions are arranged axially, facilitating staggered installation of the guide rail seats 322 on both sides.

[0034] Specifically, the guide rail base 322 includes a base body 3223 and slide rail components 3224 connected to both sides of the base body 3223, with a slide groove 3220 provided on the slide rail component 3224. Furthermore, the base body 3223 and the connecting rod 321 are integrally formed. Its structure is simple; the base body 3223 and the connecting rod 321 can be integrally formed from profiles. In this design, the connecting rod 321 adopts an arc shape, serving to connect the vertical swing arm to the horizontal base body 3223, and is more in line with the product's appearance. The slide rail components 3224 can then be directly installed on both sides of the base body 3223 later.

[0035] The connection between the linkage rod 33 and the foot slide 34 in this scheme is as follows: the foot slide 34 has a connecting frame 340 extending to the lower side of the guide rail seat 322, and one end of the linkage rod 33 is hinged to the connecting frame 340.

[0036] Specifically, the foot pedal slide 34 includes a slide body 341 and a foot pedal 342. The slide body 341 is slidably mounted on the guide rail 322, and the foot pedal 342 is connected to the upper side of the slide body 341. The connecting bracket 340 is connected to both sides of the slide body 341 and extends to the lower side of the guide rail 322. Generally, for comfort, the foot pedal 342 is made of soft materials, such as plastic or rubber. This design separates the foot pedal 342 and the slide body 341 into two components, making it easier to replace the foot pedal 342 after damage.

[0037] Furthermore, this design employs a two-sided slotting method, meaning that sliding grooves 3220 are provided on both sides of the guide rail base 322. The slide body 341 has side plates 3411 extending downwards to opposite the two sliding grooves 3220. The inner side of the side plates 3411 is provided with sliding bodies 3412 that extend into the sliding grooves 3220. Thus, after installation, the slide body 341 is positioned on the guide rail base 322 in a three-sided (top, left, and right) manner. The sliding bodies 3412 on both sides engage with the sliding grooves 3220 for guidance and sliding, resulting in a more stable structure after installation. Preferably, in this design, the sliding bodies 3412 are rollers, and multiple rollers are arranged along the length of the sliding grooves 3220, making the sliding more stable and smooth during movement and reducing any feeling of jamming.

[0038] In this embodiment of the invention, the rocker arm 31 has a hinge portion 310 that is hinged to the elliptical machine body 1. The rocker arm 311 is located above the hinge portion 310, and the upright 312 is located below the hinge portion 310. One end of the linkage rod 33 is hinged to the lower side of the upright 312. The upright 312 also has a hinge member that is hinged to the foot pedal 32. Furthermore, the upright 312 and the linkage rod 33 together restrict the foot pedal slide 34. Of course, this solution can adjust the reciprocating stroke of the foot pedal slide 34 by adjusting the connection position between the upright 312 and the linkage rod 33, for example, by making the upright 312 an adjustable length upright. That is, the distance between the connection position of the upright 312 and the linkage rod 33 and the hinge portion 310 changes after adjustment, thereby adjusting the position. For example, the upright 312 can be a telescopic rod structure, or the upright can be a multi-section structure, with the number of sections reduced by adding components to achieve adjustment.

[0039] This invention provides an elliptical trainer with an extended stride travel. It uses a rocker arm and flywheel assembly to drive the foot pedals in an elliptical trajectory when the rocker arm swings. The foot pedal slides on the foot pedals also move in an elliptical trajectory. At the same time, the foot pedal slides can slide relative to the foot pedals, thereby adding a back-and-forth sliding function for the user within the original movement trajectory, increasing the stride travel and making the product more flexible and comfortable to use.
