This application claims priority of Taiwanese Patent Application No. 106202415, filed on Feb. 20, 2017.
The disclosure relates to a body exerciser, and more particularly to a body exerciser which is configured to perform different exercising modes selected by a user.
Conventional body exercisers can perform a wide variety of exercising modes. For example, a walking exerciser includes two swing rods pivotably mounted on a frame and having upper handgrip portions and lower pedal portions. A user grips the handgrip portions and treads on the pedal portions to swing the swing rods so as to simulate a walking on a flat ground. Also, a stair stepper machine includes two pedals movably supported on a base by a resistance. A user treads on the pedals and alternately exerts forces thereon to perform a stair-climbing exercising mode. Additionally, an elliptical machine includes a four-linkage structure to have two pedal rods movable along an elliptical route so as to perform a running exercising mode.
Each of the aforesaid exercisers, which can merely provide a certain exercising mode, is operable only for one purpose of exercise and is unable to build and strengthen various body muscle groups. Hence, all the above exercisers are needed to train different muscle groups, which results in space occupation and high cost.
Therefore, an object of the disclosure is to provide a body exerciser that is operable under a wide variety of exercising modes selected by a user.
According to the disclosure, the body exerciser includes a frame unit, a first resisting unit, two linking units and a second resisting unit. The first resisting unit includes two cranks rotatably mounted on the frame unit, a first resisting member pivotably disposed on the frame unit, and a first transmitting mechanism connected between a respective one of the cranks and the first resisting member to permit synchronous rotation of the cranks and the first resisting member so as to provide a resistance to the cranks. Each of the linking units includes a handle rod which is pivotably connected to the frame unit to be swingable forwardly and rearwardly, a pedal rod which has a front portion pivotably connected to a lower end of the handle rod and which extends rearwardly from the front portion to have a middle portion and a rear portion, a swing rod which is pivotably connected to the frame unit, a first linking rod which is pivotably connected to the swing rod and the respective one of the cranks, a second linking rod which is pivotably connected between the swing rod and the pedal rod, and a connecting member which is pivotably connected to the handle rod. The second resisting unit includes a second resisting member which is pivotably disposed on the frame unit, and a second transmitting mechanism which is connected between the connecting member and the second resisting member to provide a resistance to the handle rod through the connecting member.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment with reference to the accompanying drawings, of which:
Referring to
The frame unit 2 includes a base 21, an upper front support 22 disposed on a front side of the base 21, and two lateral supports 23. The upper front support 22 includes a front rod section 221 which extends upwardly from the base 21, a rear rod section 222 which extends upwardly from the base 21 and which is disposed rearwardly of the front rod section 221, and a crosspiece section 223 which is connected between the front and rear rod sections 221, 222. Each of the lateral supports 23 is connected between the base 21 and an upper side of the rear rod section 222 and extends laterally of the base 21.
The first resisting unit 3 includes two cranks 32 which are pivotably connected to the crosspiece section 223 about an axis in a left-and-right direction, a first resisting member 33 which is pivotably connected to the rear rod section 222, and a first transmitting mechanism 31 which is connected between a respective one of the cranks 32 and the first resisting member 33 to permit synchronous rotation of the cranks 32 and the first resisting member so as to provide a resistance to the cranks 32. Specifically, the first transmitting mechanism 31 has a first primary wheel 311 which is pivotably connected to the crosspiece section 223 about the axis coaxial with that of the cranks 32, a first secondary wheel 312 which is pivotably connected to the rear rod section 222, a first primary belt 313 which is trained on the first primary and secondary wheels 311, 312, and a first secondary belt 314 which is trained on the first secondary wheel 312 and the first resisting member 33.
The second resisting unit 4 includes a second resisting member 42 which is pivotably connected to the front rod section 221 about an axis in a front-and-rear direction, and a second transmitting mechanism 41. The second transmitting mechanism 41 includes a second primary wheel 411 which is pivotably connected to the front rod section 221, a second secondary wheel 412 which is pivotably connected to the front rod section 221, a second primary belt 413 which is trained on the second primary and secondary wheels 411, 412, and a second secondary belt 414 which is trained on the second secondary wheel 412 and the second resisting member 42.
Referring to
When the user stands on the foot pedals 57 with hands grasping the handgrip portions 512 of the handle rods 51, and exerts forces on the foot pedals 57 in an alternating manner, the cranks 32 are rotated through the pedal rods 52, the second linking rods 55, the swing rods 53 and the first linking rods 54, and the first resisting member 33 is rotated as well by virtue of the first transmitting mechanism 31 to provide a resistance to the cranks 32 and to the pedal rods 52 so as to train the user's leg muscles. Since there is no linking connection between the handle rod 51 and the crank 32 on either side and each handle rod 51 is hence not affected by the first resisting member 33, the pedal rods 52 can be operated relative to the handle rods 51 with a higher degree of freedom so as to perform a variety of exercise modes selected by the user. In addition, each handle rod 51 is coupled with the second primary wheel 411 of the second resisting unit 4 through the respective connecting member 56. When the handle rods 51 are swung alternately, the second primary wheel 411 is brought into making an alternately clockwise and counterclockwise turning, which causes synchronous turning of the second resisting member 42 so as to provide the resistance to the handle rods 51. By virtue of the resistances to the handle rods 51 and to the pedal rods 52, the user performs the body exercise with a satisfactory feeling of comfort and smoothness.

As illustrated, with the handle rods 51 not directly connected to the cranks 32 of the first resisting unit 3, the pedal rods 52 can generate a variety of moving routes by virtue of the user's feet and arms so as to perform different exercising modes. Moreover, with the first and second resisting units 3, 4 cooperating with the linking units 5, the pedal rods 52 and the handle rods 51 are respectively subjected to resistances by the first and second resisting units 3, 4 so as to train different muscle groups of the user and to enhance the feeling of comfort. Furthermore, the body exerciser according to the disclosure can perform a variety of operating modes that can be selected by the user without the need to change the structure of the body exerciser, which results in cost and space saving.
While the disclosure has been described in connection with what is considered the exemplary embodiment, it is understood that this disclosure is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
