The assembling of supports 14 can be completed through the embedding relationship between the convex portions 143 and the convex portions 144. The user can selectively set a pair or more of supports 14 according to the needs, so that the pedal body 12 and the ground are at a distance, and the user can perform aerobic pedal exercises like up and down stairs.
Please also refer to FIG. 4. The bench press set 16, comprising a bench press plate 162, a support plate 164 and a support shaft 165, is detachably assembled on the cover body 123. The bench press plate 162 defines a top surface 162 a and a bottom surface 162 b. The top surface 162 a is used for users to lie down, sit or stand. The bottom surface 162 b is recessed with a second receiving portion 166 corresponding to the first receiving portion 126 to store the support plate 164. The bench press plate 162 is an example of a rectangular parallelepiped.
The bench press plate 162 further comprises two second openings 167 located on one long side thereof corresponding to the first openings 125, an accommodating groove 168 adjacent to the second receiving portion 166 for accommodating the support shaft 165, and two connecting ribs 169 parallel to the long sides thereof and provided on the bottom surface 162 b at intervals. The support plate 164 has a plate body 164 a, which is generally rectangular parallelepiped, and its short side is provided with a perforation 164 b to set the support shaft 165, and then the support plate 164 is pivotally connected to the bench press plate 162.
In addition, the pedal body 12 can optionally be provided with a screen display 15 to display related data such as the resistance value of the at least one resistance device 20, the number of training times of the at least one pull rope set 40, etc. There is a control button set 17 on one side of the screen display 15 to facilitate the user to adjust the resistance value of the at least one resistance device 20.
Through the design of the bench press set 16 of the above embodiment, in addition to the traditional standing exercise and sitting exercise, when the user needs training, the bench press set 16 can be assembled on the pedal body 12 as shown in FIG. 5. Firstly, the connecting ribs 169 of the bench press plate 162 are inserted into the positioning grooves 128, so that the bench press plate 162 is vertically arranged on the cover body 123, and then the support shaft 165 is passed through the perforation 164 b, and then the support shaft 165 in the perforation 164 b and the support plate 164 are clamped to the accommodating groove 168 together. At this time, the support plate 164 is standing on the ground and firmly supports the bench press plate 162, so that the user can lie flat on the bench press plate 162 for exercise. When the user finishes the exercise, first take out the support plate 164 together with the support shaft 165, and place it in the first receiving portion 126, so that the support shaft 165 protruding from both ends of the perforation 164 b is clamped to the clamping groove 129. Then align the second receiving portion 166 of the bench press plate 162 with the first receiving portion 126, and then insert the connecting ribs 169 into the respective receiving grooves 127, and then store the bench press set 16 in the cover 122.
Please refer to FIGS. 6 to 8. The at least one resistance device 20, at least one winding unit 30 and at least one pull rope set 40 of the preferred embodiment each take two as an example, and they are placed on opposite sides of the accommodating space 13. Each resistance device 20 is adjacent to one respective winding unit 30. Each pull rope set 40 has one end thereof wound around one respective winding unit 30, and an opposite end thereof exposing the outside of the pedal body 12 and connected to a ring handle 50 for the user to hold. The user pulls the pull rope sets 40 to drive the rotation of the respective winding units 30, and provides a resistance to the respective winding units 30 through the respective resistance devices 20. The user needs to exert more strength to overcome the resistance to pull the pull rope sets 40 to achieve the exercise effect.
Each resistance device 20 of the preferred embodiment comprises a control unit 21 and a transmission unit 22. The control unit 21 is adjacent to the transmission unit 22. The control unit 21 uses one or more electromagnets as an example, and is electrically connected to a power supply through a terminal 26. The power supply in the preferred embodiment of the present invention is a commercial power supply as an example. The transmission unit 22 comprises a first mandrel 23 and a flywheel 24. The flywheel 24 is an aluminum flywheel, and the flywheel 24 comprises a first retaining slot 241. The first mandrel 23 comprises a second retaining slot 231 corresponding to the first retaining slot 241. Position it by inserting a pin 25 between the first retaining slot 241 and the second retaining slot 231. The flywheel 24 of this preferred embodiment is arranged adjacent to the electromagnet. When the power supply provides current to the electromagnet, the magnetic field around the electromagnet changes, causing the flywheel 24 to experience hysteresis, thereby providing resistance to the winding unit 30. The stronger the magnetic field, the greater the resistance applied to the winding unit 30.
On the other hand, the transmission unit 22 further comprises a pulley set 27. The pulley set 27 of the preferred embodiment comprises a first pulley 271, a second pulley 272 and a belt 29, and the belt 29 connects the first pulley 271 and the second pulley 272.
The winding unit 30 comprises a second mandrel 32, a first belt wheel 34, a second belt wheel 36, a first guide wheel set 37 and a second guide wheel set 38. The second mandrel 32 is adjacent to the transmission unit 22. The second mandrel 32 is the shaft of the first belt wheel 34 and the second belt wheel 36 at the same time, and is fixed in the accommodating space 13 by a cover plate 31.
In other words, the first belt wheel 34 and the second belt wheel 36 are coaxially and rotatably arranged on the second mandrel 32 at a distance from each other. Both the top surface of the first belt wheel 34 and the top surface of the second belt wheel 36 have a perforation 35. The winding unit 30 of the preferred embodiment is made of aluminum as an example, and it can also be any metal material.
In detail, the first pulley 271 is set in the first mandrel 23, and the second pulley 272 is set in the second mandrel 32. The rotation of the second pulley 272 is transmitted to the first pulley 271 through the belt 29, so that the first mandrel 23 will act together with the second mandrel 32. In addition, first mandrel 23 contains a one-way ratchet 232 and a bearing 233. The bearing 233 is adjacent to the one-way ratchet 232 to maintain the axis center position of the first mandrel 23. The one-way ratchet 232 and the bearing 233 are co-located between the first mandrel 23 and the first pulley 271, so that the power can only be transmitted from the second mandrel 32 to the first mandrel 23 in one direction, causing the flywheel 24 to rotate in a single direction.
The first guide wheel set 37 comprises a rotating shaft 371, a guide shaft 372 and two guide wheels 39 as an example. The rotating shaft 371 and the guide shaft 372 are adjacent to each other and are located in the second mandrel 32 near the first opening 125. One of the guide wheels 39 is located on the rotating shaft 371, and the other guide wheel 39 is located on the guide shaft 372. The second guide wheel set 38 comprises a first rotating shaft 381, a second rotating shaft 382, a third rotating shaft 383, a fourth rotating shaft 384, a fifth rotating shaft 385 and a plurality of guide wheels 39. The second to fifth rotating shafts 382-385 are arranged in order and spaced apart around the resistance device 20 and the winding unit 30. The first rotating shaft 381 is located between the second rotating shaft 382 and the fifth rotating shaft 385, which is closer to the second mandrel 32. The length of the fifth rotating shaft 385 is shorter than the length of the first to fourth rotating shafts 381-384. The first rotating shaft 381 is mounted with one guide wheel 39. The second and third rotating shafts 382,383 are each mounted with two guide wheels 39 as an example. The fourth and fifth rotating shafts 384,385 are each mounted with one guide wheel 39 as an example. There is a gap between the guide wheels 39 on the first and fourth rotating shafts 381,384 and the base 121.
The pull rope set 40 comprises a pull rope 42 and a bungee rope 44. The pull rope 42 has one section thereof fixed to the perforation 35 of the first belt wheel 34 in a knotted manner and then wound around the first belt wheel 34, and the other section thereof bypassed the guide wheel 39 on the rotating shaft 371 and the guide wheel 39 on the guide shaft 372 in sequence and then protruded out of the pedal body 12 through the first opening 125 of the pedal body 12. The bungee rope 44 has one section thereof fixed to the perforation 35 of the second belt wheel 36 and then wound around the second belt wheel 36, and the other section thereof pulled out from the second belt wheel 36 and guided by the guide wheel 39 on the first rotating shaft 381 and then sequentially bypassed the guide wheels 39 on the second to fifth rotating shaft 382-385 and then fixed to a hook 60. The hook 60 of the preferred embodiment is adjacent to the position of the fourth rotating shaft 384. It should be noted that the winding direction of the pull rope 42 on the first belt wheel 34 and the first guide wheel set 37 is opposite to the winding direction of the bungee rope 44 on the second belt wheel 36 and the second guide wheel set 38, and the elasticity of the bungee rope 44 is higher than that of the pull rope 42.
Through the above components, in actual application, the user steps or sits or lies on the pedal 10, holding the ring handles 50 of the pull ropes 42 with both hands, and adjusts the resistance of the resistance devices 20 by the control button set 17 to control the ease of rotation of the winding units 30. In detail, when the user pulls the pull rope 42 out of the pedal 10, the pull rope 42 drives the first guide wheel set 37 and the first belt wheel 34 to rotate in the first direction, and then rotates the second mandrel 32 synchronously. The rotation of the second mandrel 32 synchronously drives the coaxial second belt wheel 36 and second pulley 272 to rotate in the first direction. In this way, the bungee rope 44 with the opposite winding direction to the pull rope 42 is rolled back to the second belt wheel 36 and is in a stretched state. The first pulley 271 rotates synchronously through the belt 29 and the second pulley 272, so that the coaxial one-way ratchet 232 drives the first mandrel 23 to rotate in the first direction when the coaxial one-way ratchet 232 rotates synchronously, and then links the pin 25 to drive the flywheel 24 to rotate.
When the user removes the force applied to the pull rope 42, the elastic force of the bungee rope 44 will drive the bungee rope 44 in the stretched state to reset, and then provide a reverse pulling force, so that the second belt wheel 36 is pulled along the way and rotates in the second direction, and synchronously drives the second mandrel 32 to rotate in the second direction. The coaxial first belt wheel 34 is driven by the second mandrel 32 to rotate synchronously, taking the pull rope 42 back to the first belt wheel 34, and the first pulley 271 is driven by the belt 29 and the second pulley 272 to synchronously rotate in the second direction. At this time, the one-way movement mechanism of the one-way ratchet 232 prevents the reverse pulling force of the bungee rope 44 from being transmitted to the first mandrel 23 and flywheel 24, and the moment of inertia of the flywheel 24 cannot be transmitted to the second mandrel 32 through the first pulley 271, making the first mandrel 23 and the flywheel 24 idling.
It can be seen from the above that when the user's hands simultaneously or alternately apply a pulling force to the pull ropes 42, the rally fitness equipment 1 of the present invention induces a magnetic attraction force through the magnetic field of the electromagnet and the flywheels 24, which hinders the rotation of the first mandrels 23 and the flywheels 24. The user needs to apply more force to the pull ropes 42 to overcome the rotation resistance of the first mandrels 23 to pull the pull ropes 42 out of the pedal body 12, which can effectively enhance the training intensity of the chest muscles and arm muscles. The invention combines a stepped pedal and pull ropes, and the user can selectively exercise the upper body and lower body. In addition to exercising different parts, the adjustable resistance devices 20 such as electromagnets and aluminum flywheels can control and adjust the pulling difficulty of the pull ropes. Indeed, the invention provides users with a practical and interesting sports equipment.
