DETAILED DESCRIPTION
[0016] The present invention provides a novel device for the inner and outer thigh exercise where FIG. 1 shows the device in close configuration and FIG. 2 shows the device in split open configuration. The user performs inner and outer thigh exercise movement in between these two configurations.
[0017] Preferred embodiments of an exercise device according to the invention are described below with reference to the attached drawings.
[0018] FIG. 1 illustrates one embodiment of the invention. In this embodiment the device 10 comprises two major member 11 and 12; member 11 connects to member 12 through the a bridge member 17 and a set of gear system under member 17 as shown in FIG. 3; where shaft 21 is locked on to member 11 and rotates freely on 17, gear 25 is locked on to shaft 21, gear 26 is locked on to shaft 22, gear 27 is locked on to shaft 23, gear 28 is locked on to shaft 24 and shaft 24 that rotates freely on 17 is locked on to member 12. Gear 25 meshes with gear 26, gear 26 meshes with gear 27 and gear 27 meshes with gear 28; therefore, rotation of gear 25 can be transferred to gear 28 in a ratio of 1:1 but opposite rotational direction. As a result, the internal angle formed by member 11 and member 17 is always equal to the internal angle formed by member 12 and member 17 during movement; the motion of member 11 referencing to member 17 is forced to mirror the motion of member 12 referencing to member 17.
[0019] FIG. 4 is an exploded view of the two-wheel system, and it illustrates one of embodiment of two-wheel system which is installed on member 11. The two-wheel system consists of two wheels of 13 which is locked on to each end of shaft 32; gear 34 is locked on to shaft 32 where enclosed by housing 33; and shaft 32 is support by two bearings of 31 which is mounted on member 11. Gear 35 is locked on to shaft 36 and gear 35 meshes to gear 34; both gear 34 and 35 are enclosed by housing 33. Rotational motion of shaft 32 can be transferred to shaft 36 by gear 34 and 35.
[0020] FIG. 5 is an exploded view of the two-wheel system, and it illustrates one of embodiment of two-wheel system which is installed on member 12. The two-wheel system consists of two wheels of 14 which is locked on to each end of shaft 42; gear 44 is locked on to shaft 42 where enclosed by housing 43; and shaft 42 is support by two bearings of 41 which is mounted on member 12. Gear 45 is locked on to shaft 46 and gear 45 meshes to gear 44; both gear 44 and 45 are enclosed by housing 43. Rotational motion of shaft 42 can be transferred to shaft 46 by gear 44 and 45.
[0021] FIG. 6 is a cross section of the device 10 and it illustrates how the two-wheel system installed on member 11 connects to the other two-wheel system that is installed on member 12. The shaft 36 is connected to flexible shaft 51 and shaft 51 is connected to shaft 46; hence, the two two-wheel systems are locked on to each other through shaft 51. The rotational motion speed of the wheel 13 on the side of member 11 can be transferred to wheel 14 on the other side of member 12 at a ratio of 1:1 in the reference to the ground while the directional of rotation of wheel 13 is opposite of the direction of rotation of wheel 14 reference to the ground. The result of this arrangement of wheel systems allows device 10 be stationary reference to the ground while the user performing inner and outer thigh exercise; this means members of device 10 is in motion during exercise but device 10's relative location to the ground will be still.
[0022] In FIG. 1, one end of member 18 that has spring like property is fixed on to member 11 and the other end of member 18 is fixed on to member 12. During the outer thigh exercise shown in FIG. 2, member 18 is stretched; the elongation of member 18 absorbs potential energy released by the user's exercise movement which in term provides the resistance force for the outer thigh exercise. On the other hand, during the inner thigh exercise, member 18 that was elongated at the end of the outer thigh exercise will provide a tension to help the user to pull up its center of mass reference to the ground. The combine effect of this arrangement allows the user to have an assisted force during the inner and outer thigh exercise. By fitting device 10 with different spring rate of member 18, the assisted forces can compensate different user's requirement.
[0023] In FIG. 1, one end of member 19 which as a fixed length is fixed on to member 11 and the other end of member 19 is fixed on to member 12. During the outer thigh exercise shown in FIG. 2, member 19 is pulled to its fixed length; therefore, member 19 limits the split angle formed by member 11 and 12. By fitting device 10 with different length of member 19, user can adjust the maximum split angle during the inner and outer thigh exercise.
