Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The foot-operated training device for the elderly as shown in fig. 1 and 2 comprises a mounting seat 1 and two groups of movable components; the mounting seat is fixed on the ground and is a closed shell with a cavity; two groups of movable components are respectively arranged at two sides of the mounting seat. The two groups of movable assemblies have the same structure, and each group of movable assemblies comprises a crank 8, a first rocker 2, a second rocker 3, a third rocker 4, a fourth rocker 5, a connecting rod 7, a pedal 6 and a motor (preferably, a speed reducing motor, not shown in the figure; an output shaft of the speed reducing motor drives a crank shaft through a gear pair); wherein, the pedals in the two groups of movable components are arranged in an up-down mode so as to adapt to the normal walking gait of the human body. The up-down and left-right directions in this embodiment are the up-down and left-right directions in fig. 2.
The motor is fixed in the cavity of the mounting seat so as to provide power for the movement of the movable assembly. The crank shaft of the crank is horizontally positioned on the mounting seat through a bearing, so that the crank is used as a driving part to drive each movable part to move.
The mounting seat, the first rocker, the connecting rod and the third rocker are sequentially hinged end to form a first parallelogram mechanism, and the connecting rod is further sequentially hinged end to end with the second rocker, the pedal and the fourth rocker to form a second parallelogram mechanism; one end of the connecting rod is hinged with the third rocker and the fourth rocker at the same time, and the other end of the connecting rod is hinged with the first rocker and the second rocker at the same time. The crankshaft is simultaneously used as a hinged shaft of the mounting seat and the third rocker; one end of the second rocker extends downwards for a certain distance, and then the bottom end of the second rocker is hinged with the swinging end of the crank; so that the second rocker becomes the drive member in each rocker.
The hinge axis of the hinge and the axis of the crank shaft are both parallel and horizontally arranged.
As can be seen, the second parallelogram mechanism is located at the upper side of the first parallelogram mechanism, i.e. the pedal is located at the top end of the whole device.
From the properties of the parallelogram mechanism it is known that: the first rocking bar and the third rocking bar are the same in length and are arranged in parallel; the second rocker and the fourth rocker are arranged in parallel; the pedals and the connecting rod are the same in length and are arranged in parallel.
As shown in fig. 3 and 4, two ends of the first rocker, the third rocker, the fourth rocker and the connecting rod are all U-shaped hinges formed by two hinge pieces, so as to improve the bearing capacity and stability of the movable assembly in the movement process. In the second rocking bar, one end of the second rocking bar is also arranged into a U-shaped hinged joint so as to be hinged with the pedal (one end of the pedal is embedded into the hinged joint of the second rocking bar and then is hinged by a hinged shaft which horizontally passes through); the middle part of the second rocker is provided with a U-shaped hinge joint so as to be hinged with the connecting rod (one end of the connecting rod is embedded into the hinge joint and then is hinged by a hinge shaft passing through horizontally); the hinge sheet positioned at the outer side in the middle U-shaped hinge joint also extends downwards and is used as the other end of the second rocker to be hinged with the swinging end of the crank. The U-shaped hinges at the two ends of the first rocker, the third rocker and the fourth rocker are also hinged as shown in FIG. 1, and are not described in detail.
The length parameters of all parts in the motion assembly are designed as follows: the length of the crank (i.e. the distance between the two hinge holes; the same applies hereinafter) is 80 cm; the lengths of the first rocker and the third rocker are 26 cm; the length of the second rocker is 53 cm; the length of the fourth rocker is 26 cm; the length of the pedal and the connecting rod is 28 cm; the design parameters can meet the normal use requirements of most of the old (the foot length of the normal old is generally 23cm-27 cm); all parameters of the embodiment can be amplified or reduced in a certain proportion according to actual conditions so as to adapt to the old people with different foot lengths.
The motors in the two groups of movable assemblies are respectively and electrically connected with a controller (preferably a single chip microcomputer, not shown in the figure) so that the controller can control the rotating speeds of the two groups of motors and further control the movement speed of the pedal, thereby meeting the requirements of the old on different pace speeds.
The utility model discloses a use as follows:
when the trainer of the utility model is used, an exerciser firstly puts two feet on the two pedals respectively, then the motor is turned on to drive the motor to drive the crank to rotate, the crank drives the pedals to do up-and-down motion and left-and-right small-amplitude motion along the normal gait track of the human body through the coordinated motion of the rockers and the connecting rods, and the lower limb training of the exerciser is realized; in addition, in the use, the exerciser can be according to self condition, through the rotational speed of two sets of motors of controller control, and then the movement speed of control footboard to the demand of adaptation different paces.
