Abstract
The utility model discloses an automatic resupine abdomen exercising machine which comprises a base and a backrest. The utility model is characterized in that the base is hinged with the backrest. A motor, a speed reducer and a crank link mechanism are also arranged on the lower part of the base, wherein a crank of the crank link mechanism is fixedly connected with the output end of the speed reducer, and the tail end of the crank link mechanism is fixed in the middle of the back surface of the backrest. When the utility model is used, a bracket is supported. The crank link mechanism is driven by the speed reducer to move to drive the backrest to be collected and placed further. The utility model is used for people to carry out abdomen exercise and training in an enforced mode.
Description
This utility model relates to a kind of physics body-building apparatus, relates in particular to a kind of abdomen exercising machine of lying on the back automatically.
Raising along with people's living standard, people are more and more higher to the health requirements of health, for the fat partially people of person in middle and old age's abdominal part, it is very difficult to perform physical exercise, yet the various fitness equipment majorities of selling on the market are running, weight lifting etc., and majority are by pulling or the mobilizable arm-chair of hand push is finished do abdominal crunch on chair, the promptly bothersome abdominal exercise purpose that do not reach again of such exercise, therefore, be that the public expects for abdominal exercise provides a kind of body-building equipment.
The purpose of this utility model is to provide a kind of abdomen exercising machine of lying on the back automatically, and this abdomen exercising machine of lying on the back automatically can make the people carry out abdominal exercise automatically, forcibly, to reach the purpose of body-building and fat-reducing.
For achieving the above object, technical solution adopted in the utility model is: a kind of abdomen exercising machine of lying on the back automatically, comprise a pedestal and the backrest hinged with it, it is characterized in that: the bottom of described pedestal sets firmly a motor and a decelerator that is connected by shaft coupling, an end of an affixed crank on the output shaft of this decelerator, one end of the hinged connecting rod of the other end of crank, an end of the hinged fixed bar of the other end of connecting rod, the other end of fixed bar then is fixed in the middle part, the back side of backrest.
Fixed bar is the knee with angle, and its bent angle is 140-170 °.
The rotating speed of motor output after decelerator slows down is 10-100r/min.
Owing to adopt said structure, during use, motor is after decelerator slows down, the crank that is fixed on the decelerator rotates around reducer output shaft, drivening rod, fixed bar and backrest exhibition folding move thereby make the sporter carry out abdominal exercise forcibly simultaneously, thereby have realized the purpose of exercise and fat-reducing; Because backrest is made up of forward and backward two backrests, and is provided with corresponding slideway between two backrests, the feasible friction of avoiding human body back and backrest when moving.
Below in conjunction with the drawings and specific embodiments this utility model is described in detail.
Description of drawings:
Fig. 1 is lie on the back the automatically perspective view of abdomen exercising machine of this utility model;
Fig. 2 is lie on the back the automatically side view of abdomen exercising machine of this utility model;
Fig. 3 is that this utility model abdomen exercising machine of lying on the back automatically is in the side view of extended configuration.
Referring to Fig. 1, a kind of abdomen exercising machine of lying on the back automatically, comprise a pedestal 1 and the backrest 2 hinged with it, it is characterized in that: the bottom of described pedestal 1 sets firmly a motor 3 and a decelerator 4 that is connected by shaft coupling, an end of an affixed crank 5 on the output shaft of this decelerator 4, one end of the hinged connecting rod 6 of the other end of crank 5, an end of the hinged fixed bar 7 of the other end of connecting rod 6, the other end of fixed bar 7 then is fixed in the middle part, the back side of backrest 2.The knee of fixed bar 7 for having angle, its bent angle is 140-170 °.
The rotating speed of motor output after decelerator slows down is 10-100r/min.
Referring to Fig. 2,3, the place ahead of pedestal 1 can further be provided with the carriage 11 that can prop and regain.Carriage 11 is made up of supporting plate 12, pole 13 and stick 14, and supporting plate 12 is articulated in the front upper place of pedestal 1, pole 13 be can unidirectional-folding connecting rod constitute, the one end is articulated in the back side of supporting plate 12, the other end is articulated on the rotary crossbeam axle 15 of pedestal; Stick 14 joins with crossbeam axle 15.This carriage can be made of a supporting plate, and this supporting plate can pull out or push back from along continuous straight runs on the pedestal.
Motor 3 can adopt stepless speed-change motor, and its rotating speed can be regulated automatically, and the output speed of decelerator 4 is-100 rev/mins of 10 commentaries on classics.
During use, referring to Fig. 2, Fig. 3, after motor 3 slows down through decelerator 4, the output shaft of decelerator 4 drives crank 5 and rotates around output shaft, thereby drivening rod 6, fixed bar 7 motions further spur shaking of backrest 2, realize automatically, the abdominal exercise of abdominal crunch forcibly.During motion, owing between the back of health and the backrest 2 relative friction is arranged, when especially Yun Dong frequency is very high, it is particularly violent to rub, therefore backrest of the present utility model further is made up of forward and backward backrest 21,22, and be respectively equipped with slideway and rolling element (not drawing among the figure) between the forward and backward backrest, the friction that produces when overcoming motion.
What should give explanation is: this utility model puts down carriage 11 when not using, backrest is transferred to the appropriate location, can the double as sofa, seat and bed use.
