Abstract

The fitness machine comprises a body, two pedals and two rotating members. The body is provided with an inclined slope surface. The front parts of the two pedals slide along the slope surface. The two pedals are connected to each other so that when the front part of one pedal is at the highest position, the front part of the other pedal is at the lowest position. The two rotating members are both rotatable relative to the body about a first rotating shaft and are hinged to the rear parts of the corresponding pedals. Since the rear parts of the two pedals are hinged to one rotating member, the front parts move along the slope surface. The movement track of the front parts of the two pedals is a straight line, and the movement track of the rear parts is a curve. When the user steps on the pedals alternately, the movement track of the user is closer to the movement of stepping up and down stairs than the prior art.

Description

Technical fields: This utility model relates to a fitness device. Background technology: There are various types of fitness equipment in the current technology to meet different needs. Taking the elliptical track exercise bike as an example, the existing structure is as follows: Figure 1 Figure 2 As shown, the exercise equipment includes a main body 1, a damping mechanism 2, and a transmission mechanism A. The main body 1 has two inclined, fixed-angle support rods 11. The damping mechanism 2 is mounted on the main body 1 between the two support rods 11. The transmission mechanism A includes two connecting rods A1, two cranks A2, and two rollers A3, each mounted on either side of the damping mechanism 2. The two rollers are mounted near the middle of the two connecting rods A1. Pedals A4 are mounted at the rear of the two connecting rods, and their front parts are hinged to the two cranks A2. The two cranks A2 are fixed to the flywheel 21 of the damping mechanism 2, ensuring that the two cranks are set at 180 degrees along the flywheel axis. The two rollers A3 rest on the two support rods 11. During exercise, the user alternately steps on the two pedals, causing the two connecting rods to rotate around the flywheel axis and rotate together with the flywheel, while the two rollers slide up and down along the two support rods. In this exercise bike structure, the movement trajectory of the user's feet is approximately elliptical. Utility Model Content: In view of the above-mentioned problems of the prior art, the purpose of this utility model is to provide a fitness device in which the movement trajectory of the feet is closer to the movement of going up and down stairs than that of the prior art.

[0001] To achieve the above objectives, the present invention adopts the following technical solution: Option 1: A fitness device includes a main body, two pedals and two rotating parts. The main body has an inclined slope. The front parts of the two pedals slide along the slope. The two pedals are linked to each other so that when the front part of one pedal is at its highest position, the front part of the other pedal is at its lowest position. The two rotating parts rotate relative to the main body around a first axis and are hinged to the rear part of the corresponding pedal.

[0002] In the above technical solution, since a rotating component is hinged to the rear of the two pedals and the front moves along the slope, the movement trajectory of the front of the two feet is a straight line and the movement trajectory of the rear is a curve, so that the movement trajectory of the exerciser when the two feet alternately step is closer to the movement of going up and down stairs than the existing technology.

[0003] Option 2: Based on Option 1, the two rotating components are two rocker arms, both of which rotate relative to the main body around the first axis and are hinged to the rear of the corresponding pedal.

[0004] In the above scheme, the two rotating components are two swing arms, which is a specific embodiment structure. The two swing arms swing around the first rotating axis to ensure that the rear movement trajectory of the two pedals is an arc curve around the first rotating axis.

[0005] Option 3: Based on Option 1 and Option 2, the front parts of the two pedals are respectively hinged to a sliding assembly, which moves along the slope.

[0006] The above technical solution is a specific structure in which the front part of the two pedals moves along the slope, ensuring that the slider assembly, pedals and two swing arms form a crank-slider mechanism, so that the movement trajectory of the front part of the two pedals is a straight line and the movement trajectory of the rear part is a curve.

[0007] Option 4: Based on Option 3, the sliding component includes a seat and a roller. The front parts of the two pedals are respectively hinged to the upper part of the seat, and the roller is installed on the lower part of the seat. The roller moves in a rolling manner along the slope.

[0008] The above technical solution is a specific embodiment of the sliding component. The front parts of the two pedals are respectively hinged to the upper part of the seat, and the rollers are installed in the lower part of the seat. The rollers roll along the slope to reduce friction.

[0009] Option 5: Based on Option 4, a damping mechanism is installed on the main body, and a connecting rod is fixedly connected to each of the two bases. A crank is hinged to the movable end of each of the two connecting rods. The two cranks are fixedly connected to the flywheel of the damping mechanism installed on the main body, and the two cranks are set at 180 degrees along the flywheel axis.

[0010] The above technical solution involves the connection structure between the damping mechanism on the exercise bike body and the two pedals. This is achieved by connecting two links fixed to the seat and hinged to a crank, which in turn drives the flywheel of the damping mechanism to rotate. Compared to existing technologies, the addition of a swing arm at the rear of each pedal, with its front hinged to the seat and connecting links, creates an additional point of rotation. Furthermore, the installation of rollers on the seat allows the user's footwork trajectory to more closely resemble the movement of going up and down stairs when alternating between pedals, a feature more closely resembling that of climbing stairs.

[0011] Schemes 6 and 7, based on Schemes 5 and 6, feature a U-shaped base with two connecting rods fixed to its base plate. The slope is formed on the upper surfaces of two inclined support rods on the main body, and the rollers are mounted on the two inclined support rods and move up and down along their upper surfaces in a rolling motion.

[0012] The above technical solution defines the specific structure of the seat and the slope. The U-shaped seat structure allows the two connecting rods to be integrally formed with it and hinged to the two pedals respectively, resulting in a compact structure. The slope is formed by the upper surfaces of the two support rods on the main body, allowing two rollers to be mounted on the two inclined support rods and move up and down along their upper surfaces in a rolling motion. This ensures structural stability and reduces frictional resistance.

[0017] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0018] Figure 3-6 The figure shows an embodiment of this utility model: A fitness device includes a body 1, a damping mechanism 2, and a transmission mechanism 3. The body has two inclined, fixed-angle support rods 11. The damping mechanism 2 is mounted on the body 1 between the two support rods 11. The transmission mechanism 3 cooperates with the damping mechanism 2. The transmission mechanism 3 includes: two pedals 31, two swing arms 32, two seats 33, two rollers 34, two connecting rods 35, and two cranks 36. The rear parts 311 of the two pedals 31 are respectively hinged to the two swing arms 32, and the two swing arms 32 are respectively hinged to a first rotating shaft 12 on the body 1. The front parts 312 of the two pedals 31 are respectively hinged to the two seats 33. The two seats 33 are U-shaped seats. Two rollers 34 are installed in the two U-shaped seats below the hinge points of the two pedals 31. The two rollers 34 are mounted on two inclined support rods 11. The side plates of the two U-shaped seats can extend downward and limit wheels 37 are installed at the lower part of the two support rods 11 to ensure that the rollers do not jump off the support rods 11. Two connecting rods 35 are integrally formed on the bottom plates of the two U-shaped seats. The other ends of the two connecting rods 35 are respectively hinged to two cranks 36. The two cranks 36 are fixed to the flywheel 21 of the damping mechanism 2 and drive the flywheel 21 to rotate as a whole. The two cranks 36 are set at 180 degrees along the axis of the flywheel 21.

[0019] When the above structure is in motion, the exerciser alternately steps on the two pedals with both feet. The overall movement of the transmission mechanism 3 makes the movement trajectory of the front part of the two pedals 31 a straight line and the movement trajectory of the rear part a curve, so that the movement trajectory of the exerciser when alternating steps is closer to the movement of going up and down stairs than the existing technology.

[0020] The purpose of this invention is to improve the existing technology so that the movement trajectory of the two pedals is closer to the movement of going up and down stairs. The improvement is to hinge a swing arm to the rear of the two pedals and add a movable rotation point (hinge point) to the front. This improved structure makes the movement trajectories of the front and rear of the two pedals 31 different. The movement trajectory of the front is a straight line and the movement trajectory of the rear is a curve, ensuring that the movement trajectory of the user when alternating between the two feet is closer to the movement of going up and down stairs than the existing technology. The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
