The support 6 is provided with a support member 7 for abdominal exercise exercise; the support member 7 can be a cushion, or can be replaced with other members used to support the human body exercise, for example, the use of an arc-shaped plate 13, an arc-shaped plate The method is as described in the second embodiment below.
具体说，所述支架包括转动端和翻折端；所述转动端与所述前支架的顶端通过第一转轴铰接，所述翻折端活动连接有作收腹运动锻炼时供用户倚靠的靠背。Specifically, the bracket includes a rotating end and a turning end; the turning end is hinged with the top end of the front bracket through a first rotating shaft, and the turning end is movably connected with a backrest for the user to lean on during abdominal exercises. .
如图1所示，所述的支架6转动端与前支架2顶端铰接，所述前支架2上还设置有第一限位装置，所述第一限位装置用以限制或固定所述支架6的旋转角度。例如，在折叠状态下，支架6在脚踏板上方，用户可以在支撑部件7上锻炼身体，在展开状态下，限位装置保持支架6的展开状态，避免支架6再次折叠影响脚踏板使用。第一限位装置包括限位板8和限位杆9，位于前支架2顶端中间位置固定有限位板8，限位板8上具有开口朝下的限位槽，所述的支架6上配合安装有支架6直立翻折时卡入所述限位槽内的限位杆9。如图4所示，使用时，只需将支架6直立起来，限位杆9便卡入限位槽内，保持支架6的直立状态，避免支架6绕着第一转轴随意转动，为踏步运动预留出空间。As shown in Figure 1, the rotating end of the bracket 6 is hinged with the top end of the front bracket 2. The front bracket 2 is also provided with a first limiting device, and the first limiting device is used to limit or fix the bracket 6 rotation angle. For example, in the folded state, the bracket 6 is above the pedal, and the user can exercise on the supporting member 7. In the unfolded state, the limit device keeps the bracket 6 in the unfolded state to prevent the bracket 6 from being folded again and affecting the use of the pedal. . The first limiting device includes a limiting plate 8 and a limiting rod 9. The limiting plate 8 is fixed in the middle of the top end of the front bracket 2. The limiting plate 8 has a limiting slot with an opening facing downward, and the bracket 6 is matched with When the bracket 6 is upright and folded, a limit rod 9 is installed that snaps into the limit slot. As shown in Figure 4, when using, only need to stand the support 6 upright, the limit rod 9 will be locked into the limit slot, keep the support 6 upright, prevent the support 6 from rotating randomly around the first axis of rotation, which is a stepping motion Set aside space.
第一种实施方式：位于支架6后端的翻折端通过第二转轴活动连接有作收腹运动锻炼时供用户倚靠的靠背10，所述靠背形成以第二转轴为支点的杠杆。所述的靠背10包括铰接杆10-1，所述铰接杆10-1顶端通过第三转轴铰接有撑杆10-2，铰接杆10-1和撑杆10-2之间设有第二限位装置，可使铰接杆10-1与撑杆10-2之间绕着第三转轴转动，或是两者之间保持一定角度的固定状态(例如，可以保持铰接杆10-1和撑杆10-2的折叠状态，避免触碰时改变其状态占据额外空间；在使用时保持保持铰接杆10-1和撑杆10-2的对接直立状态避免影响锻炼)。撑杆10-2顶端设有两组上下布置靠垫10-3，所述靠垫10-3由一根连杆和两个分设在连杆两端的软质柱形垫组成。软质柱形垫通过连接轴连接在连杆上，软质柱形垫与用户背部接触，在用 户背部向后仰时，软质柱形垫可以绕着连接轴滚动，达到按摩的效果。The first embodiment: the folded end at the rear end of the bracket 6 is movably connected with a backrest 10 for the user to lean on during abdomen exercise exercise through a second rotating shaft, and the backrest forms a lever with the second rotating shaft as a fulcrum. The backrest 10 includes a hinge rod 10-1, the top of the hinge rod 10-1 is hinged with a support rod 10-2 through a third rotating shaft, and a second limit is provided between the hinge rod 10-1 and the support rod 10-2. The positioning device can make the hinge rod 10-1 and the support rod 10-2 rotate around the third axis, or maintain a certain angle between the two in a fixed state (for example, the hinge rod 10-1 and the support rod can be maintained The folded state of 10-2 avoids changing its state when touching and occupying additional space; keep the hinged rod 10-1 and the support rod 10-2 upright when in use to avoid affecting the exercise). The top of the support rod 10-2 is provided with two sets of back cushions 10-3 arranged up and down. The back cushions 10-3 are composed of a connecting rod and two soft cylindrical cushions respectively arranged at both ends of the connecting rod. The soft cylindrical pad is connected to the connecting rod through the connecting shaft, and the soft cylindrical pad is in contact with the user's back. When the user's back is tilted back, the soft cylindrical pad can roll around the connecting shaft to achieve a massage effect.
支架6上设有调节靠背10后仰力度的拉力弹簧11，拉力弹簧11的一端与靠背10的远离支点的位置连接，另一端与转动端连接。拉力弹簧11与所述靠背10产生力矩，可以让拉力弹簧11拉紧靠背10通过支点向转动端方向转动。用户在利用靠背10锻炼腹部时，需要用背部紧贴靠背10向后倾斜，靠背克服拉力弹簧11的弹力才能改变靠背10的角度达到锻炼腹部肌肉的目的。在返回时，用户撤销背部向后倚靠的力，靠背在弹簧的拉力作用下沿所述第二转轴转动恢复靠背原有的状态，如此反复锻炼。拉力弹簧11设置在所述支架6内，也可以设置在支架6外。The bracket 6 is provided with a tension spring 11 for adjusting the backward force of the backrest 10. One end of the tension spring 11 is connected with a position away from the fulcrum of the backrest 10, and the other end is connected with the rotating end. The tension spring 11 generates a moment with the backrest 10, so that the tension spring 11 can tighten the backrest 10 to rotate in the direction of the rotation end through the fulcrum. When using the backrest 10 to exercise the abdomen, the user needs to lean back against the backrest 10 with his back, and the backrest overcomes the elastic force of the tension spring 11 to change the angle of the backrest 10 to exercise the abdominal muscles. When returning, the user withdraws the force of the back leaning back, the backrest rotates along the second rotation axis under the action of the spring to restore the original state of the backrest, and repeats exercises in this way. The tension spring 11 is arranged inside the bracket 6 and can also be arranged outside the bracket 6.
通过调节螺栓12以调整拉力弹簧11的弹力。符合不同强度的用户对力量的需求。设置的调节螺栓12，所述调节螺栓12设置在所述转动端，拉力弹簧12第二端与调节螺栓连接。The elastic force of the tension spring 11 is adjusted by adjusting the bolt 12. Meet the power needs of users of different intensities. The adjusting bolt 12 is arranged, the adjusting bolt 12 is arranged at the rotating end, and the second end of the tension spring 12 is connected with the adjusting bolt.
第二种实施方式：所述的支撑部件7包括弧形板13，弧形板13上铺设有软垫。The second embodiment: the supporting member 7 includes an arc-shaped plate 13 on which a soft pad is laid.
不使用时，如图3所示将收腹踏步机折叠后收拢存放。When not in use, as shown in Figure 3, fold the abdomen stepper and fold it for storage.
作踏步运动时，如图4所示，将支架6翻折成直立状，靠背10也直立翻折贴合在支架6上，用户保持踏步状态，双脚分站在左右两个脚踏板3上，用力蹬踏即可进行踏步锻炼。在坐垫足够长的状况下，支架竖起之后用户可以手扶座垫顶部，脚部蹬踏脚踏板3锻炼。进行收腹锻炼时，如图5所示，将支架6翻折成水平状贴合在两个脚踏板3上，用户坐在支撑部件7上，背靠在靠背10，连续作后仰起身动作，即可进行收腹训练。When performing a stepping exercise, as shown in Figure 4, the bracket 6 is folded into an upright shape, and the backrest 10 is also upright folded and attached to the bracket 6. The user keeps the stepping state, standing on the left and right foot pedals 3 separately. Stepping exercise can be done by pedaling hard. When the seat cushion is long enough, the user can hold the top of the seat cushion with his hands after the support is erected, and pedal the pedal 3 with his feet for exercise. When performing abdomen exercise, as shown in Figure 5, the bracket 6 is folded into a horizontal shape and attached to the two footrests 3, the user sits on the support member 7, backs against the backrest 10, and continuously leans back Action, you can carry out abdomen training.
本实用新型有机地将踏步运动与收腹运动集成于一体，起到了一机两用的锻炼效果，设备占地面积小，适合家庭及公共场所用户使用。The utility model organically integrates the stepping movement and the abdomen movement, which has a dual-purpose exercise effect of one machine. The equipment has a small area and is suitable for users in households and public places.
