The use of indoor exercise equipment is different from outdoor exercise, but at present, indoor exercise equipment in different areas can train the muscles of each part of the body, and users can do physical fitness training at home and indoors, The purpose of rehabilitation can be achieved, and therefore, the indoor exercise equipment is applied to a wide range of users. For example, treadmills, steppers, rowing machines, training bicycles, and the like are indoor exercise equipment often used by users. Recently, various new products for indoor exercise equipment have appeared. Among them, an elliptical motion machine that forms an elliptical motion trajectory is a preferable product especially for general users, and the current elliptical motion machine is the basis. Although the effect of training physical fitness can be obtained, when the conventional elliptical exercise machine exercises, the formed elliptical motion trajectory is a single form, so the major axis and minor axis of the elliptical trajectory cannot be changed. The inventor proposed an exercise machine capable of changing an elliptical trajectory, which is a patent of US Pat. No. 6,277,054. On the other hand, all of the conventional elliptical exercise machines are practically inconvenient because the adjustment is performed after the user stops operating when changing the motion trajectory. In order to eliminate the above inconvenience, the inventor of the present invention
We proposed an elliptical machine that is in operation and can be changed, which is the patent of 6,620,079.

Hereinafter, specific structures and operations of the present invention will be described in detail with reference to the drawings.

Referring to FIGS. 1 and 2, the elliptical exercise machine includes a kite frame (1) for mortgage against the floor surface, and the kite frame (1) has a front base (11) at the front end and a rear end. There is a rear base (12), there is a front vertical frame (13) extending upward from the front end of the heel frame (1), and an instrument panel (14) is provided on the front vertical frame (13). The other frame (121) of the rear base (12) is provided with a flywheel (30) that can rotate on the shaft support lever (34) and a crank (3) that drives the flywheel (30). The rear base (12) is further provided with a weight wheel (32) and an electromagnetic brake (33) for supplying resistance.

On the front base (11), the cradle (16) fixed on the base body (15) of the front vertical frame (13) is extended, and the pair of left and right swing arms (2) are The base body (17) and (18) are pivotally supported on the base (16) so that they can stand on both sides of the base body (15) and swing. The A pair of master connecting rods (6) is formed with a storage chamber (600) (as shown in FIG. 5), and the rod body of the swing arm (2) is formed by a shaft rod (62) in the middle stage. A long penetrating tank (61) is formed in advance on one side of the master connecting rod (6), and is supported by the lower end. The movable connecting rod (7) is pivotally supported by a shaft joint (71) at the lower end, and the shaft joint (70) at the upper end of the movable connecting rod (7) is It is pivotally mounted on the frame (13).

One end of the pair of step connecting rods (4) is supported on the shaft (31) of the crank (3), and the user stands on the top of the step connecting rod (4). A step panel (40) is provided, and an upper pulley device (42) and a lower pulley device (41) are provided on the side surface of the step connecting rod (4). One end of the pair of intermediate connecting rods (5) is directly supported on the shaft base (60) of the master connecting rod (6), and the other end is connected to the upper pulley device (42) and the lower slide. The intermediate connecting rod (5) can be displaced between the step pulley connecting rod (4) and the lower pulley devices (42), (41). Positioned. A pair of elevating connecting rods (8) is provided through the long straight tank (21) of the swing arm (2) so that the shaft joint (81) at one end can be displaced upward and downward, Since the technology relating to this part is the patent technology of the inventor US Pat. No. 6,620,079, detailed description is omitted here. The other end of the elevating connecting rod (8) is pivotally supported on the pivotal support shaft (31) of the crank (3).

5 and 6, the master connecting rod (6) has the actuator (9) mounted in the storage chamber (600), and the actuator (9) is connected to the adjustment link (91) by the adjustment link (91). Connected to the retarder (81) and the motor (82), a joint (92) is provided on the other end of the actuator (9), and is positioned on the joint (92) by the shaft rod (920). By passing through the long penetrating tank (61), it is fixed to the shaft joint (71) of the movable connecting rod (7), and when the actuator (9) is extended, the actuator (9) The connecting joint (71) of the movable connecting rod (7) is displaced by being biased, and this displacement causes the step length, which is the elliptical motion locus of the step panel (40) on the step connecting rod (4). You can change the size.

The elliptical exercise machine is a reciprocating motion that alternately swings the left and right swing arms (2) with both hands of the athlete, and the left and right step panels (40) with both feet of the athlete to step on the flywheel (30) The trajectory of the stepping panel (40) becomes an elliptical trajectory. In the present invention, when the movable connecting rod (7) is displaced in the master connecting rod (6), the major axis distance of the elliptical motion trajectory is changed, that is, the step length that the athlete's feet step on is changed.

2, 3 and 4, when the left swing arm (2) is swung in the forward direction away from the user's body in the state shown in FIG. 2, the state shown in FIG. The lower and lower ends of the swing arm (2) interlock the elevating connecting rod (8), the crank (3) moves counterclockwise, and the left swing arm (2) moves in the direction of the athlete. When pulled back, the state becomes as shown in FIG. 4, and the step connecting rod (4), the elevating connecting rod (8) and the crank (3) are all connected to the shaft support shaft (31). Thus, the step panel (40) on the step connecting rod (4) is caused to move circumferentially by the crank (3) to form an elliptical movement locus.

As described above, when changing the major axis of the elliptical trajectory, that is, when changing the size of the stride of the exerciser, if the position of the movable connecting rod (7) in the master connecting rod (6) is adjusted, To adjust the movement of the motor (82) on the swing arm (2) in order to be able to change the step size of the exerciser and to allow the user to perform adjustments while exercising during operation The switch (19) is provided and the position of the movable connecting rod (7) in the master connecting rod (6) can be adjusted with the actuator (9), so that the operation is simple and practical . In the present invention, another switch (10) for adjusting the height of the lifting connecting rod (8) in the swing arm (2) is provided on the other swing arm (2). In addition, it may have a function of changing the minor axis of the elliptical motion trajectory, and the present invention becomes more practical when combined with the above-described technology already disclosed in US Pat. No. 6,620,079. .
